Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used to correct the holding manner of a grasped rod typified by chopsticks and writing utensils, and to use the grasped rod by attaching it to the grasped rod. It does not adversely affect the body at the time of use, can be used on a daily basis, and relates to a tool for correcting how to hold a grasped rod that can be easily used, and is particularly preferably used for chopsticks, The present invention relates to a tool for correcting how to hold a grasped rod that can be applied to a writing instrument.

[0002]

2. Description of the Related Art Generally, in the correct way of holding a grasped rod such as chopsticks or a writing instrument, a position for grasping the grasped rod,
Key points include the shape of the hand and the force applied when the gripped rod is gripped, and the gripping angle of the gripped rod.

[0003] Here, when the gripped rod is held in an incorrect manner, there are many problems in the position of gripping the gripped rod, that is, the above points. If there is a problem with this point, not only is there a problem with the gripping position, but there is also a problem with the point "the shape of the hand and the amount of force applied". As a result, the gripped rod cannot be used properly, and
The body is also adversely affected. In addition, the above points
If there is a problem with the
It is clear that this will also be adversely affected.

Therefore, conventionally, the present inventor has proposed a holding-corrected gripping stick and a gripping-correction assisting tool for the gripping stick in consideration of the above problems (JP-A-11-0.
No. 07236 (Japanese Patent Application No. 9-324829).

[0005] The holding-corrected gripping rod and the holding-correction assisting tool (abbreviated as the correcting gripping rod and correction assisting tool, respectively)
Has at least one protrusion, and a contact surface for contacting a thumb is provided on the rear end side of the gripped rod in the protrusion, while the upper surface of the protrusion and The upper side surface of the gripped rod that is continuous with the upper side surface of the protruding portion serves as the contact surface of the index finger.

In the straightening grasped rod and the straightening aid having the above-mentioned configuration, when the grasped rod is grasped, the positional relationship between the three fingers of the thumb, the index finger and the middle finger and the holding grasped rod is physically defined. Will be. Moreover, the contact state of the index finger, which is the main body for moving the gripped rod, is more stable than before, and moreover, the thumb only slightly contacts the contact surface, which is more than necessary for the thumb having an auxiliary role. Force is avoided. As a result, it is possible to easily correct the holding manner of the gripped rod, so that the conventional correction gripped rod and the correction assisting tool described above are excellent in that they can grip the gripped rod very appropriately with a simple configuration. It has become a thing.

[0007]

By the way, since gripped rods such as chopsticks and writing instruments are used on a daily basis, the way of holding the gripped rod is corrected from the viewpoint of education for children. It is preferable that the correction target gripping rod and the correction assisting tool be cheaper and easier to obtain. In fact, the above-mentioned conventional orthodontic gripping rods and orthodontic aids have a simple structure and can use general plastics as raw materials, so they are very inexpensive and easy to obtain as finished products. Has become.

However, even though the above-mentioned conventional correction target gripping rod and correction assisting tool have a simple structure, they have a shape that is not common in the plastic molding process, and therefore a special mold is used. Without it, it cannot be molded. therefore,
Considering the mold allowance, even the conventional correction target gripping rod and correction assisting tool may have a relatively high manufacturing cost.

Also, the use of chopsticks and writing instruments is everyday,
Moreover, if you continue to hold it incorrectly, you may not only be able to use chopsticks and writing instruments skillfully, but you may also have problems such as applying stress to your fingers and arms and causing stiffness in your shoulders.
Correcting how to hold is very important. However, under normal circumstances, there is a tendency for few users to try to correct the way of holding chopsticks and writing instruments unless they are pointed out by others. Therefore, for example, if a correction aid or the like is distributed free of charge for sales promotion of some product or service, it becomes possible to make the user recognize again how to correct the way to hold the gripped rod.

[0010] However, although the above-mentioned conventional orthodontic gripping rods and orthodontic aids are inexpensive as finished products, they are not so inexpensive that they can be used for free delivery as described above. Also, although the structure as a molded product is simple, the mold itself becomes expensive because the mold itself has an uncommon shape as described above, and as a result, the corrective gripping rod and the correction aid also have a mold allowance. It is expensive because it is added. Therefore, if it is used for free distribution, it is preferable that the structure is simpler and the price is lower.

The present invention has been made in view of the above problems, and its object is to have a very simple structure and a low cost, and to be similar to the conventional gripping rod for gripping or a gripping aid for gripping. An object of the present invention is to provide an assisting device for correcting a method of holding a grasped rod that can be easily corrected.

[0012]

In order to solve the above-mentioned problems, an assisting tool for holding a gripped rod according to the present invention has the following object.
An annular member, and a shape having a shape capable of combining the annular members, including a spacing member that holds a constant spacing between a pair of rod-shaped members, at least one of which is a gripped rod, In the state in which the annular members are combined with the spacing member, the annular members protrude from positions facing each other, and the protruding annular members enable the rod-shaped members to be mounted respectively. It is characterized in that a pair of small circular rings are formed, and only one of the circular ring member and the spacing member has elasticity and is capable of expanding and contracting.

According to the above structure, when the grasped rod to which the correction assisting tool is attached is grasped, the thumb, which is apt to receive excessive force, out of the three fingers that support the grasped rod, which must be freely movable, is natural. And the index finger and the middle finger make sufficient contact so that the index finger and the middle finger act as the main body for moving the gripped rod. Therefore, the gripped rod can be easily moved. Moreover, due to the elasticity of the annular member or the spacing member, even if the force of the index finger / middle finger is changed, the position of the gripped rod easily returns to its original position, and the gripped state does not shift. As a result, by using the correction assisting tool according to the present invention, it is possible to easily, surely and efficiently acquire the correct way to hold the chopsticks.

In addition, the above-mentioned structure has a very simple structure in which the annular member and the spacing member are essential members and can be formed only by combining them. For each of these members, rubber bands and tubes that are generally commercially available can be used, so that the cost can be further reduced as compared with the conventional correction assisting tool. As a result, the correction aid according to the present invention can be used for free distribution, for example.

In the correction assisting device for holding a grasped rod, the annular member is preferably an elastic annular member which has elasticity and is capable of expanding and contracting, and the elastic annular member is constant. More preferably, it is a strip-shaped rubber band having a width of.

According to the above construction, even if the force of the index finger / middle finger that moves the gripped rod is changed by the spring action due to the elasticity of the elastic annular member, the position of the gripped rod easily returns to the original position. Therefore, if the above-mentioned correction aid is used, even if the force applied to each finger is changed by using the grasped rod, the grasped state does not shift. As a result, it is possible to easily, surely, and efficiently learn how to hold the gripped rod correctly.

Moreover, if a rubber band is used as the elastic annular member, the rubber band having such a shape is sufficiently contained in a commercially available rubber band. Therefore, in producing the correction aid according to the present invention, it is not necessary to newly form a rubber band having a special inner diameter, and therefore, a mold used for extrusion molding of the rubber band is not special and is commonly used. Anything can be used. As a result, the cost of the correction aid can be further reduced.

In the correction assisting device for holding a gripped rod, the spacing member is a tubular member, and the annular member is inserted into the hollow portion of the tubular member and formed at both ends in a combined state. It is preferable that the pair of small circular rings be formed by the circular ring members protruding from the respective openings.

According to the above construction, in the case of a tubular member, it is possible to easily realize a combined state in which a small annular ring is formed simply by inserting the elastic annular member into the hollow portion, and the tubular member is Since generally commercially available tubes can be preferably used, the cost can be further reduced as compared with the conventional correction aid. As a result, the correction aid according to the present invention can be made inexpensive so that it can be used for free delivery.

In the assisting tool for holding a grasped rod, the tubular member has a linear notch formed so as to be connected to the hollow portion along the longitudinal direction of the outer peripheral surface thereof. Good.

According to the above construction, it is possible to easily insert the elastic annular member into the hollow portion through the cutout portion so as to be assembled. Further, since the elastic annular member does not face the cutout portion only by rotating the assembled elastic annular member by, for example, about 90 °, it is possible to sufficiently stabilize the combined state. it can.
Further, when removing the elastic annular member, since it is sufficient to rotate the elastic annular member so as to face the cutout portion, the removal can be facilitated.

Further, in the above-mentioned tool for correcting the holding manner of the gripped rod, the spacing member is a scissor-like member capable of sandwiching the annular members so as to form the pair of small annular rings. May be.

According to the above construction, if the scissors-like member sandwiches the elastic annular member between the pair of flat plates, for example, the sandwiching force of each flat plate and the elasticity of the elastic annular member are By the antagonistic action, the combined state of the scissors-like member and the elastic annular member is stabilized, and the correction assisting tool similar to the above tubular members can be obtained. Moreover,
Since the combined state can be realized simply by sandwiching the elastic annular member between the sandwiching portions such as a pair of flat plates, the correction assisting device can be more easily assembled.

Further, in the above-described holding-correction assisting device for holding a gripped rod, the spacing member is a lump member fixed inside the annular member so as to form the pair of small annular rings. May be.

According to the above construction, the block-shaped member serving as the spacing member is arranged and fixed inside the elastic annular member. Therefore, although the elastic annular member and the spacing member are not separable from each other, they are completely fixed, so that the stability of the correction assisting tool can be further improved.

In the correction assisting device for holding the gripped rod, or alternatively, the spacing member is a coil-shaped member, and the annular member is inserted into the hollow portion of the coil-shaped member and assembled. The pair of small circular rings may be formed by circular ring members protruding from the openings formed at both ends.

According to the above structure, when the correction assisting tool in which the coiled member and the elastic annular member are combined is used, the elasticity of the elastic annular member and the coil in the state where the grasped rod is attached to the small annular member. Due to the shape stability of the coiled member in a state where the wound portion is in close contact, the gripped rod is sandwiched between the coil-shaped member and the elastic annular member to be stabilized, and a fixed distance is maintained between the gripped rods. Can be secured. Therefore, it is possible to obtain a correction aid similar to that of the tubular member.

Moreover, for example, when holding a chopstick to which a correction aid using the coil-shaped member is attached, the coil-shaped member serves as a stable spacing member due to the contracting action of the elastic annular member. Since the winding parts are not adhered to each other, it is possible to shift the winding parts according to the position of the thumb when gripped. As a result, the coil-shaped member can be placed in a state along the placement of the thumb, and the position of the thumb can be more reliably defined.

In the above-mentioned correction assisting device for holding the gripped rod, the inner diameter of the small circular ring which changes according to the outer diameter of the gripped rod to be mounted is fixed while being fitted in the small circular ring. It may include a small ring inner diameter holding member for holding.

According to the above construction, by fitting the small ring inner diameter holding member into the small ring, the shape of the small ring can be held in a substantially complete ring shape (substantially perfect circle shape). for that reason,
The gripped rod can be easily attached to the small ring. As the small circular inner diameter holding member, a short pipe having a cutout portion can be preferably used, so that the structure can be prevented from becoming complicated.

In the correction assisting device for holding the gripped rod, the spacing member is a bellows member having a plurality of continuous pleats, which is elastic and expandable. Even if the pair of small circular rings are formed by the circular ring members protruding from the openings formed at both ends in a state where the circular ring members are inserted and combined in the hollow portion of the member. Good.

According to the above construction, the annular member hardly expands or contracts, but the bellows-like member serving as the spacing member has elasticity and elasticity. Therefore, the bellows-like member separates the gripped rods from each other to maintain a certain distance, and the separation force of the bellows-shaped member and the annular member having shape stability hold the attached state of the gripped rods. Can be stabilized. As a result, it is possible to obtain a correction assisting tool that exhibits the same function as that of the correction assisting tool using the tubular member.

In the correction assisting device for holding the gripped rod, the vicinity of the small ring formed in the spacing member is the contact surface of the gripped rods which are substantially parallel to each other. It is preferable that the surface is formed as an inclined surface that is inclined with respect to a direction substantially orthogonal to the separating direction of the gripped rod.

According to the above construction, when a correction assisting tool which is a combination of the spacing member having the inclined surface and the annular member is attached to, for example, chopsticks, the correction assisting tool (spacing member).
Is tilted between the chopsticks. For example, when the chopsticks attached with such a correction assisting tool are grasped, the inclination direction of the spacing member and the arrangement direction of the thumb are substantially parallel to each other, so that the position of the thumb can be more accurately defined by the correction assisting tool. it can. Therefore, more correct chopsticks (holding stick)
Can be realized.

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] The following will describe a first embodiment of the present invention with reference to FIGS. The present invention is not limited to this.

The holding aid for holding a grasped rod according to the present invention mainly uses chopsticks as a grasped rod. That is, the present invention mainly relates to a correction assisting tool for correcting how to hold the chopsticks. However, as will be described later, it can be used not only for chopsticks but also for correcting how to hold a writing instrument (see Embodiment 9).

The method for holding the gripped rod according to the present invention (hereinafter, simply referred to as "correction assisting tool") comprises at least a combination of an elastic annular member and a spacing member. The spacing member is a shape that allows the elastic annular members to be combined, for example, a pipe-shaped tubular member, and the elastic annular member is inserted into the hollow portion of the tubular member and combined, A pair of small circular rings are formed by the elastic circular ring members protruding from the respective openings formed at both ends. Each of the small circular rings can be attached with a gripped rod.

In the above structure, since the gap holding member (tubular member) is arranged between the pair of bar-shaped chopsticks, a constant gap is held between the chopsticks. Moreover, due to the elasticity of the elastic ring member, the small ring stably attaches the chopsticks,
The position of the chopsticks can also be specified stably. for that reason,
You can learn how to hold chopsticks correctly, easily, reliably and efficiently. Further, the cost can be further reduced as compared with the conventional correction assisting tool.

Specifically, as shown in FIGS. 2 (a) and 2 (b), the correction assisting tool 10 according to the present embodiment has a rubber band 11 as an elastic annular member and a tubular member as a tubular member. As shown in FIG. 2 (c), including the spacer 12, the rubber band 11 penetrates the hollow portion of the tubular spacer 12 and is assembled. Rubber band 11
Protrude from both ends of the tubular spacer 12, and each of them forms a small circular ring 11a. To attach the correction assisting tool 10 to chopsticks, as shown in FIG. 1, only a pair of chopsticks 5 consisting of chopsticks 5a and 5b is inserted into each of the small rings 11a.

As the rubber band 11, a wide rubber band available on the market can be used. The rubber band is very inexpensive, and when the chopsticks 5a and 5b are attached to the small circular ring 11a, the chopsticks 5a and 5b attached by the elasticity and the friction of the surface of the chopsticks 5a and 5b are attached. Each can be effectively and reliably retained. further,
As shown in FIG. 1, when the pair of chopsticks 5 is attached to the correction aid 10, not only is the gap between the chopsticks 5a and 5b kept constant, but the elasticity of the chopsticks 5 holds the chopsticks 5 as well. The chopsticks 5 can be freely moved by the applied external force.

In particular, when the chopsticks 5 are properly held, one of the pair of chopsticks 5 is fixed so that it is almost immovable, while the other is required to be freely movable. . Therefore, by using the rubber band 11 as the elastic annular member, the other can be freely moved, and the repulsive force / restoring force easily keeps the pair of chopsticks 5 at a constant distance. Can be recovered.

That is, in the present invention, by using the rubber band 11 as the elastic annular member, the pair of attached chopsticks 5 can be firmly bound together while maintaining a constant interval, while the chopsticks 5 can be flexibly bent. It is possible to realize the contradictory function of being able to move. As a result, it is possible to easily grasp the chopsticks 5 in a correct way by simply attaching the chopsticks 5 to the correction assisting tool 10 of the present invention.

The shape of the rubber band 11 is not particularly limited, but it is preferable to use one having a constant band width W as shown in FIG. 2 (a). The specific value of the band width W is not particularly limited as long as the chopsticks 5a and 5b can be sufficiently fixed and supported when the chopsticks 5a and 5b are attached to the small circular rings 11a. However, it is usually preferable that the range is more than 5 mm and less than 15 mm (5 mm <W <15 mm), and 8 mm or more and 12
It is more preferably within the range of 8 mm or less (8 mm ≦ W ≦ 12 mm), and particularly preferably about 10 mm (W≈10 mm).

If the band width W is 5 mm or less, the chopsticks 5 may not be sufficiently fixed and supported by the small ring 11a. On the other hand, when the length is 15 mm or more, the rubber band 11
Spacing member (tubular spacer 1
It may be necessary to upsize 2). However,
Depending on the shape of the spacing member or the shape of the chopsticks 5, the band width W may be preferably 5 mm or less or 15 mm or more, and is not particularly limited.

The rubber band suitably used as the rubber band 11 is usually formed into a tube shape, and can be obtained by cutting the tube into a predetermined width. Therefore, the band width W of the rubber band 11 may be appropriately set during the cutting process.

In the correction assisting tool 10 according to the present invention, the small annular rings 11a and 11a protruding from both ends of the tubular spacer 12 in the state where the rubber band 11 is combined with the tubular spacer 12 are sufficient for the chopsticks 5a. It suffices to have a width such that 5b can be fixedly supported. In other words, the rubber band 11 does not necessarily have to have the constant band width W as a whole, but has a certain width only at the portion protruding from the tubular spacer 12, and the hollow portion of the tubular spacer 12 has a certain width. The width of the part to be stored in may be smaller than that.

The thickness of the rubber band 11 is not particularly limited either, and when the rubber band 11 is combined with the tubular spacer 12 to form the correction assisting tool 10, the pair of chopsticks 5 can be sufficiently held by the small circular ring 11a. Any thickness may be used as long as it can secure the strength. For example, the commercially available rubber band mentioned in the present embodiment has a thickness of about 1 mm, which is practically sufficient.

The inner diameter of the rubber band 11 is particularly limited as long as the length for holding the pair of chopsticks 5 at a constant interval can be secured when the correction aid 10 is combined with the tubular spacer 12. Not a thing. The distance between the pair of chopsticks 5 slightly varies depending on the size of the palm (palm) of the user who uses the correction assisting tool 10, but the distance itself is determined by the length of the tubular spacer 12.

Therefore, the elastic rubber band 11 only needs to have an inner diameter capable of ensuring the above-mentioned interval in a stretched state to some extent, and it is not necessary to finely limit the size of the inner diameter. However, in normal use, a preferable range can be set, and thus a preferable range of the inner diameter will be described later.

Further, the elastic annular member is not limited to the rubber band 11 (wide rubber band),
When the orthodontic aid 10 is combined with the tubular spacer 12, the chopstick 5 may be sufficiently worn. The material is not limited to a narrowly defined rubber material such as natural rubber, various synthetic rubbers, and reclaimed rubber, and may be an elastomer material having rubber-like elasticity at room temperature. The above-mentioned elastomer material can be preferably used as the material of the elastic annular member, but it does not necessarily have to be a material having rubber-like elasticity and may be another material as long as it has elasticity and stretchability to some extent. May be.

The tubular spacer 12 shown in FIG.
As shown in (b), it is sufficient if it has a pipe shape having openings 12a and 12a formed at both ends and a hollow portion inside, and the shape is not particularly limited.
That is, in the tubular spacer 12, the elastic annular member, which is the rubber band 11 in the present embodiment, can be inserted and combined with the hollow portion. Openings 12a and 12a
The rubber bands 11 stick out from the
It suffices that the a · 11a is formed.

The shape and the like of the openings 12a formed at both ends of the tubular spacer 12 are not particularly limited, and the small annular ring 11a can be formed after inserting the rubber band 11. It is sufficient if it can be made to protrude. Here, the both ends are portions (contact surfaces) of the tubular spacer 12 arranged between the chopsticks 5a and 5b, which substantially directly contact the chopsticks 5a and 5b. Therefore, it is preferable that the both end portions are contact surfaces that are substantially parallel to each other. therefore,
The opening 12a can be regarded as a hole formed in the contact surface.

As a concrete shape of the tubular spacer 12, as shown in FIGS. 3 (a), (b), and (c), its cross section is a circle, a rectangle, an ellipse, or the like, and has a predetermined shape. There is no particular limitation as long as it has a pipe shape having a length.

Further, the material of the tubular spacer 12 is not particularly limited, and the rubber band 1 is provided in the hollow portion.
Any material can be used as long as it can be held in the state of the correction assisting tool 10 in which 1 is inserted and combined. For example, various rubber materials and elastomer materials similar to the rubber band 11,
Various plastic materials that are more rigid than elastomeric materials, silicone resins, paper materials that have a certain degree of rigidity such as cardboard, wood / bamboo materials, metal materials, etc. Materials are preferably used.

As the inner diameter D of the tubular spacer 12,
A rubber band 11 as an elastic ring member can be easily passed through the hollow portion, and is not particularly limited as long as it does not become larger than the outer diameter of each chopstick 5a / b to the extent that the grip of the chopstick 5 is affected. is not. The tubular spacer 12
If the inner diameter D is too small, the rubber band 1
1 is difficult to insert, which is not preferable.

In the present embodiment, for example, in the case of the tubular spacer 12 having a substantially circular cross section as shown in FIGS. 2B and 3A, the inner diameter D is the band width of the rubber band 11. Slightly smaller than the thickness of W or equivalent (W ≒
D) is preferable, but not limited thereto. Further, in the case of the tubular spacer 12 having a substantially rectangular or substantially elliptical cross section as shown in FIGS. 3B and 3C, the longitudinal direction of each cross section is the inner diameter D, and the inner diameter D is the band width W. It should be about the same as That is, in this embodiment,
The maximum diameter of the cross section of the tubular spacer 12 is defined as the inner diameter D, and the inner diameter D only needs to be large enough to insert the rubber band 11, and the specific numerical value is not particularly limited.

The length L of the tubular spacer 12 is the distance between the chopsticks 5 when the pair of chopsticks 5 is attached to the correction aid 10. Therefore, the length L of the tubular spacer 12 is appropriately set according to the size of the palm of the user who uses the chopsticks 5, and is not particularly limited.

The interval between the pair of chopsticks 5 will be described based on the correct way of holding the chopsticks 5 shown in FIG.

When the chopsticks 5 are gripped, as shown in FIG. 4, the lower chopsticks 5b (hereinafter referred to as the lower chopsticks 5b) come into contact with the vicinity of the base of the thumb and are almost immobile.
The upper chopstick 5a (hereinafter referred to as the upper chopstick 5a) is supported by the tips of the thumb, the index finger, and the middle finger. At this time, the thumb is only lightly applied to the upper chopsticks 5a, while the index finger and the middle finger are guaranteed a high degree of freedom. Therefore, the index finger and the middle finger are mainly used to move the upper chopsticks 5a. In other words, if the chopsticks 5 are properly held, the upper chopsticks 5a can be freely moved,
The lower chopsticks 5b are fixed so as to be almost immobile.

Here, as is apparent from FIG. 4, in the correct way of holding the chopsticks 5, the lower chopsticks 5b that are almost fixed at the bottom.
A constant distance H is secured between the upper chopsticks 5a and the upper chopsticks 5a supported so as to be able to move freely. The distance H is from the vicinity of the base of the thumb for fixing and supporting the lower chopsticks 5b to the upper chopsticks 5a when the chopsticks 5 are held.
Since it is movably supported, it can be considered that it corresponds substantially to the length up to the vicinity of the tip of the thumb. Therefore, when the chopsticks 5 are correctly grasped, the distance H between the upper chopsticks 5a and the lower chopsticks 5b is
It will depend on the size of the palm of the user.

In this way, the above-mentioned upper chopsticks 5a-lower chopsticks 5b
The interval H is not necessarily limited to a clear numerical range because there are individual differences in the size of the palm, but in general, it is within a range of 10 mm to 25 mm for children, and for adults, It is in the range of 20 mm or more and 35 mm or less. Therefore, in the case of children, the length L of the tubular spacer 12 is within the range of 10 mm or more and 25 mm or less (1
0 mm ≦ L ≦ 25 mm), and in the case of an adult, it is generally within a range of 20 mm or more and 35 mm or less (20 mm ≦ L ≦ 35 mm).

Of course, the actual length L of the tubular spacer 12 may deviate from the above range depending on the size of the palm of the user. Therefore, as the tubular spacer 12, a long one is prepared in advance so that the user can appropriately cut the tubular spacer 12 into a predetermined length according to the size of his / her palm. Is more preferable. Therefore, as a more preferable material for the tubular spacer 12,
Among the above-mentioned various materials, rubber materials, elastomer materials, plastic materials, paper materials and the like can be mentioned. These materials are preferable because they are inexpensive and can be easily cut with scissors or a cutter knife. Therefore, as the tubular spacer 12, it is possible to preferably use commercially available tubes made of the above-mentioned materials.

Here, the length L of the tubular spacer 12 is
When the preferable range of (that is, the above-mentioned constant interval H) is determined, the preferable range of the inner diameter R of the rubber band 11 as the elastic annular member is also automatically determined. As described above, the rubber band 11 is projected to the extent that the small annular ring 11a is formed from the openings 12a at both ends when the rubber band 11 is attached to the tubular spacer 12. Therefore, the length of the annular rubber band 11 “crushed” into a substantially flat plate shape is
It may be longer than the length L of the tubular spacer 12 to some extent.

Specifically, as shown in FIG. 5A, when the inner diameter (diameter) of the rubber band 11 is R, FIG.
As shown in, the length C of the rubber band 11 in the “crushed” state in a substantially flat plate shape is about πR / 2 (about half of the circumference) (C≈πR / 2). And the length of the tubular spacer 12 is L
Then, it is sufficient that C≈πR / 2 is larger than L (πR / 2> L). In addition, in fact,
The rubber band 11 is completely “crushed” due to its elasticity.
Since the state does not occur, the length C is slightly smaller than πR / 2.

Here, the rubber band 11 protruding from the tubular spacer 12, that is, the pair of small circular rings 11a-1.
1a must be able to be fixedly supported with the above chopsticks 5a or chopsticks 5b (herein collectively referred to as chopsticks 5) attached. Therefore, the inner diameter of the small ring 11a is equal to that of the chopsticks 5. It must be slightly smaller than the outer diameter.
If the inner diameter of the small circular ring 11a is equal to or larger than the outer diameter of the chopsticks 5, the chopsticks 5 are simply inserted into the small circular ring 11a and cannot be sufficiently fixed and supported.

On the other hand, the inner diameter of the small circular ring 11a is 5
If the diameter is smaller than the outer diameter of
When you put on the small ring 11 because the outside diameter of the chopsticks 5 is larger
The rubber band 11 forming a is stretched. Therefore, the chopsticks 5 are sufficiently fixed and supported by the contraction effect of the rubber band 11 which tends to return from the stretched state to the original state.

The outer diameter of the chopsticks 5 referred to here means the maximum width in the cross section of the chopsticks 5. Therefore, it goes without saying that the chopsticks 5 used in the present invention are not limited to those having a circular cross section, and may have, for example, a substantially equilateral triangle or a substantially square cross section.

Here, since the stretching action of the rubber band 11 forming the small circular ring 11a is limited, if the inner diameter of the small circular ring 11a is too small, it becomes difficult to put on the chopsticks 5 this time. It is not preferable. Therefore, the small ring 11a allows the user, such as a child, who does not have power to easily use the chopsticks 5.
It is preferable that the inner diameter is such that the can be mounted. For example, in the commercially available rubber band used in the present embodiment, in consideration of its stretching action, the length when the small circular ring 11a is “crushed” into a substantially flat plate shape is substantially equal to the outer diameter of the chopsticks 5. A degree is preferable. Therefore, from this point, the preferable range of the inner diameter of the small circular ring 11a in the present embodiment can be determined.

Specifically, as shown in FIG. 5 (c), assuming that the inner diameter (diameter) of the small circular ring 11a is r, although not shown, the small circular ring 11a is in a substantially flat plate shape in a "crushed" state. The length of the chopsticks is about πr / 2 (approximately half of the circumference),
Then, it is preferable that S≈πr / 2, and therefore it is preferable that the diameter r≈2S / π of the small ring 11a (about 0.64 times the diameter S of the chopsticks 5). .
The diameter S of the general chopsticks 5 is in the range of 5 mm or more and 9 mm or less at the position where the correction aid 10 is attached (5 mm ≦
Since it is often (S ≦ 9 mm), it can be calculated from the above relational expression that the inner diameter r of the small circular ring 11a is preferably within the range of 3 mm or more and 6 mm or less (3 mm ≦ r ≦ 6 mm).

Of course, the cross-sectional shape of the chopsticks 5 and the rubber band 11
Depending on the subtle difference in material and the shape of the tubular spacer 12, the inner diameter r of the small ring 11a may deviate from the above range in actual use. Therefore, it is needless to say that the limitation of the inner diameter r of the small circular ring 11a described above is a range that can be generally regarded as preferable, and the correction assisting tool 10 according to the present invention is not limited to this.

In practice, the small circular ring 11a does not have a perfect ring shape as shown in FIG. 5 (c).
That is, as shown in FIG. 2C, the actual small ring 11
a has a shape that is narrowed down on the tubular spacer 12 side and draws an arc on the side opposite to the tubular spacer 12, that is, a "drop-like" shape. Therefore, the inner diameter r of the small ring 11a is a concept for convenience in explaining the size of the small ring 11a.

Considering the preferable range of the inner diameter r of the small ring 11a, the preferable range of the inner diameter R of the rubber band 11 (elastic ring member) can be obtained from the length L of the tubular spacer 12. it can. That is, the length C of the rubber band 11 in the “crushed” state shown in FIG.
Is the length L of the tubular spacer 12 and the two small circular rings 11a.
It is only necessary to equal the sum of the length of the “crushed” state in π and the length πr / 2 (approximately half of the circumference), so that C≈L + (πr
/ 2) × 2≈πR / 2 is established.

Therefore, the length L of the tubular spacer 12 is
From the preferable range of and the preferable range of the inner diameter r of the small circle sum, the inner diameter R of the rubber band 11 is generally in the range of 13 mm or more and 27 mm or less (13 mm ≦ R ≦ 27 mm) for children, In the case of adults, it is generally within the range of 19 mm or more and 34 mm or less (19 mm ≦ R ≦
34 mm) is preferable.

Rubber band 1 having an inner diameter R within the above range
Since 1 will be sufficiently contained in commercially available rubber bands,
In producing the correction assisting tool 10 according to the present invention, it is not necessary to newly form the rubber band 11 having a special inner diameter, and therefore, the mold used for the extrusion molding of the rubber band 11 is not special and is generally used. Anything can be used. Therefore, the price increase of the correction assisting tool 10 can be further avoided.

Further, in the present invention, the rubber band 11 may have a surface on the inner peripheral side which is processed with silicone. If the surface on the inner peripheral side is treated with silicone, it is possible to impart non-slip properties.
With the chopsticks 5 attached to a, the chopsticks 5 can be held in a stable attached state. The silicone processing method is not particularly limited, and a general rubber band 11 is used.
The technology of processing silicone during manufacture of is known. Alternatively, the rubber band 11 may be inverted to expose the surface on the inner peripheral side to the outer peripheral side, and a known silicone agent may be sprayed.

Next, a method of using the pair of chopsticks 5 to which the above-mentioned correction aid 10 is attached will be described.

As shown in FIG. 1, the correction assisting tool 10 according to the present embodiment has a position of about 70 to 80% when viewed from the tip of the chopstick 5, that is, 20 to 30% when viewed from the rear end of the chopstick 5. The pair of chopsticks 5 is fixedly supported in a state of being held at a constant interval H (the length L of the tubular spacer 12) at a position corresponding to the length.

As described above, in the correct way of holding the chopsticks 5, the lower chopsticks 5b are mainly supported by the "crotch" part near the base of the thumb, while the lower chopsticks 5b are slightly supported by the vicinity of the hairline of the nail of the ring finger. While the upper chopsticks 5a
Is the tip of the thumb and the tip of the index finger, and the first of the middle finger
Side of index finger near joint (near fingernails)
(See FIG. 4).

In the present invention, the correct holding of the chopsticks 5 can be realized as shown in FIG. 6 only by attaching the orthodontic aid 10 to the pair of chopsticks 5 and gripping them. Specifically, when the chopsticks 5 are properly held (see FIG. 4), the lower chopsticks 5b abutted near the base of the thumb are the lower chopsticks 5b.
The position is about 70 to 80% when viewed from the tip of. Therefore, by attaching the correction assisting tool 10 to this position (see FIG. 1), as shown in FIG. 6, about 70 to 80% when viewed from the tip of the lower chopstick 5 b near the base of the thumb. The lower chopsticks 5b can be supported at the position.

Further, when the upper chopsticks 5a, which are held at a certain distance H (the length L of the tubular spacer 12) from the lower chopsticks 5b, are held as they are, as shown in FIG.
60 to 70 when viewed from the tip of the upper chopsticks 5a with the above three fingers
It will support the position of about%.

That is, the small circular ring 1 on the lower chopstick 5b.
When the position of 1a is brought into contact with the vicinity of the base of the thumb, the distance between the lower chopsticks 5b and the upper chopsticks 5a becomes the length L of the tubular spacer 12.
The orthodontic aid 10 is defined by the upper chopsticks 5.
Both a and the lower chopsticks 5b are fixed and supported substantially in parallel. Therefore, the upper chopsticks 5a are automatically arranged above the lower chopsticks 5b simply by gripping the pair of chopsticks 5 to which the correction aid 10 is attached.
60 fingers viewed from the tip of the upper chopsticks 5a
About 70% of the positions are naturally supported.

Further, the correction aid 10 is provided with a pair of chopsticks 5.
When the rubber band 11 is attached to the pair of chopsticks 5, the rubber band 11 exerts a contracting force in a direction in which the pair of chopsticks 5 are in close contact with each other, as shown by an arrow P in FIG. The formed tubular spacer 12 is arranged to face the contraction force of the rubber band 11 and to secure a constant space H between the pair of chopsticks 5. Therefore, each chopstick 5a or 5b
Is fixed so as to be sandwiched between the end of the tubular spacer 12 and the small circular ring 11a (a part of the rubber band 11).

In the above structure, since the pair of chopsticks 5 are held at a constant distance by the correction aid 10, the upper chopsticks 5a and the lower chopsticks 5b are held in a very stable positional relationship. Even though the pair of chopsticks 5 are fixedly supported by the correction aid 10, the main body that actually fixes and supports the chopsticks 5 is the small ring 11a formed by the rubber band 11. is there. Therefore, especially the upper chopsticks 5
The elastic force of the rubber band 11 allows a to be freely moved by the three fingers, and the chopsticks 5a shown in FIG. The chopsticks 5a and 5b can be separated from each other to bring them into a substantially parallel state from the state where the tips of the 5b are brought into contact with each other, as shown in FIG.

In the process of picking something with the pair of chopsticks 5 (the state shown in FIG. 6) and then releasing it (the state shown in FIG. 7), the direction of the force applied to the three fingers for moving the upper chopsticks 5a is particularly changed. I have to change. At this time, if the way of holding the chopsticks 5 is unstable, the position of the upper chopsticks 5a immediately shifts, and it becomes impossible to hold the chopsticks 5 correctly.

However, the correction aid 1 according to the present invention
At 0, the entire rubber band 11 acts as an elastic body, and excellent repulsive force / restoring force can be exhibited. Therefore, even if the force applied to the three fingers is changed, the upper chopsticks 5a can be surely returned to the original position (see FIG. 7), and the lower chopsticks 5b can be sufficiently fixed. Particularly, in the present invention, since the elastic action of the rubber band 11 exerts a very excellent restoring force, it is possible to stabilize the position of the upper chopsticks 5a above the conventional correction aid 10 for molded articles. Become.

Here, the constant interval H secured between the pair of chopsticks 5 substantially corresponds to the length of the thumb as described above. Therefore, when the chopsticks 5 are gripped in the state where the space H is secured, the thumb among the three fingers supporting the upper chopsticks 5a is lightly abutted merely to support the position of the upper chopsticks 5a. Only the index and middle fingers are actually used to move the upper chopsticks 5a. As a result, the upper chopsticks 5a easily move with respect to the substantially fixed lower chopsticks 5b side, but it becomes difficult to move in other directions.

For example, as shown in FIG. 8, when a pair of chopsticks 5 is held, a plane A formed by the chopsticks 5a and 5b is formed.
Can be assumed. As long as the tip of the upper chopsticks 5a is in the direction in which the tip portion approaches or separates from the tip portion of the lower chopsticks 5b (X direction in the drawing), that is, in the plane A that spreads in the XY direction in the drawing, It can be easily moved with three fingers. This is because, of the three fingers that come into contact with the upper chopsticks 5a, the thumb only comes into contact with lightly to support the position.

In other words, for example, in FIG. 8, when the X-Y-Z coordinate system is set assuming the X axis and the Y axis in the spreading direction of the plane A and the Z axis in the normal direction of the plane A. The tip of the upper chopstick 5a is movable within the plane A, that is, within the range (Z = 0) where the Z coordinate is always 0 in the coordinates (X, Y, Z). However, it is difficult to move in the direction deviating from the plane A, that is, in the direction of (X, Y, Z) where the Z coordinate component is not 0 (Z ≠ 0).

That is, the chopsticks 5 to which the correction aid 10 is attached
When the chopsticks are gripped, the chopsticks 5a and 5b can be easily moved by moving the tip portions of the chopsticks 5a and 5b close to or apart from each other, but it is difficult to move the chopsticks 5a and 5b in the other directions.

A typical way of holding the chopsticks 5 by mistake is cross chopsticks. In the cross chopsticks, the upper chopsticks 5a move away from the plane A formed by the pair of chopsticks 5 (Z coordinate). (The component of is not 0)). As described above, the biggest cause of the upper chopsticks 5a coming off the plane A is that the thumb is excessively pressed. On the other hand, in the correction assisting tool 10 according to the present invention, since the position of the thumb is naturally defined by the spacing member, the chopsticks 5 to which the correction assisting tool 10 is simply attached are attached.
By simply gripping, it is possible to reliably avoid a state in which excessive force is applied to the thumb.

In addition, since the pair of chopsticks 5 are fixedly supported by the small ring 11a formed of the rubber band 11, the force of each finger is applied after the upper chopsticks 5a are moved by three fingers. When changed, as shown in FIG. 8, the elastic recovery force of the rubber band 11 automatically moves the position of the upper chopsticks 5a to a position before the movement, that is, a position substantially parallel to the lower chopsticks 5b with a constant distance. Will return to.

As described above, when the correction aid according to the present invention is used, of the three fingers that support the upper chopsticks, the thumb, to which excessive force is likely to be applied, only naturally and lightly contacts the upper chopsticks. At the same time, the index finger and the middle finger are sufficiently abutted so as to be the main body for moving the upper chopsticks. Therefore, the upper chopsticks
It can be easily moved only in the plane formed by a pair of chopsticks, and it is relatively difficult to move it out of the plane. Also, due to the spring action of the rubber band that constitutes the correction aid, even if the force of the index and middle fingers is changed, the position of the upper chopsticks will easily return to the original position, and the use of chopsticks will keep the upper chopsticks and lower chopsticks gripped. It will not shift.

Therefore, it is possible to easily grasp the chopsticks in a correct holding manner only by attaching the correction assisting tool according to the present invention to the pair of chopsticks and grasping the chopsticks. Moreover, by making this a habit, you can learn how to hold chopsticks correctly, easily, reliably and efficiently.

Moreover, in the correction assisting tool according to the present invention, as described above, the elastic annular member such as the rubber band and the spacing holding member such as the tubular spacer are essential members and can be formed only by combining them. It has a very simple structure. Furthermore, as described above, since rubber bands and tubes that are generally commercially available can be used for each member, the cost can be further reduced as compared with the conventional correction aid. As a result, the correction aid according to the present invention can be made inexpensive so that it can be used for free delivery.

Further, since the orthodontic aid can be obtained only by combining the tubular spacer and the rubber band, for example, the tubular spacer and the rubber band are separately provided, and the kit is assembled appropriately by the user. You can also Therefore, the correction assisting tool according to the present invention can exhibit the same functions as the conventional ones, and can also be preferably used as a free distribution application such as a sales promotion product or a product as an appendix.

[Second Embodiment] The second embodiment of the present invention will be described below with reference to FIGS. 9 and 10. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment has basically the same configuration as the correction assisting tool according to the first embodiment, except that a cutout portion is formed in the longitudinal direction of the tubular spacer. Is different.

Specifically, as shown in FIG. 9A, the correction assisting tool 20 according to the present embodiment has almost the same configuration as that of the first embodiment, and the same as that of the first embodiment. In addition, it is composed of a combination of a tubular spacer (tubular member) 13 having openings 13b at both ends (contact surfaces) and a rubber band 11. However, as shown in FIG. 9C, a linear notch 13a is formed on a part of the side surface of the tubular spacer 13 along the longitudinal direction of the outer peripheral surface thereof. The portion 13a is in a state of being connected to the hollow portion.

Therefore, as shown in FIG. 9B, the cross section of the tubular spacer 13 has a shape obtained by cutting a part of a circle,
For example, it will be shaped like the letter "C" of the alphabet (Fig. 9).
In (b) and (c), "C" is shown in an inverted state).

In the correction assisting tool 20 according to the present embodiment, as shown in FIG. 9 (b), when the tubular spacer 13 is assumed to have a diameter line E which extends the diameter passing through the cutout portion 13a, it is inserted. Rubber band 1
It is preferable that the band line F extending in the band width direction of 1 is substantially orthogonal to the diameter line E. With such a configuration, the rubber band 11 has the cutout portion 13
It is possible to further stabilize the combined state by avoiding the situation of falling out of a.

The direction in which the rubber band 11 is combined with the tubular spacer 13 in the present embodiment will be described. First, as shown in FIG. 10A, the cutout portion 13a is "crushed" into a substantially flat plate shape. Push the rubber band 11 of. As a result, as shown in FIG.
The rubber band 11 can be easily inserted and incorporated in the hollow portion of the tubular spacer 13.

Here, if the rubber band 11 is simply inserted, the arrangement of the rubber band 11 is such that the diameter line E and the band line F substantially coincide with each other, as shown in FIG. 10 (b). In this state, the end of the rubber band 11 substantially faces the notch 13a, so that the small ring 1 is left as it is.
There is a possibility that the rubber band 11 may come off from the tubular spacer 13 via the notch 13a due to an external force applied when the chopsticks 5 are attached to the la 1a.

Then, when the rubber band 11 is rotated by about 90 ° while being assembled in the tubular spacer 13, as shown in FIG.
As shown in (c), the band line F is substantially perpendicular to the diameter line E, and the end of the rubber band 11 is cut out.
As in the first embodiment, the inner surface of the tubular spacer 13 comes into contact with the inner surface of the tubular spacer 13 without facing 3a. Therefore, the state in which the rubber band 11 is inserted into the hollow portion of the tubular spacer 13 and combined can be sufficiently stabilized. Further, when removing the rubber band 11, the tubular spacer 13 may be rotated about 90 ° so that the end of the rubber band 11 faces the notch 13a, so that the rubber band 11 can be easily removed. Becomes

As the tubular spacer 13 in this embodiment, the same one as in the first embodiment can be used except for the notch portion 13a, but the material thereof is relatively more rigid than the rubber band 11. It is preferable that the material is high.

As shown in FIG. 9B, the tubular spacer 13
In the state in which the rubber band 11 is inserted and combined with the rubber band 11, the elasticity of the rubber band 11 exerts a force from the inside to the outside of the tubular spacer 13 along the direction of the band line F, while the tubular spacer 13 does not. Due to the rigidity, it tries to maintain the tube shape. Here, in the present embodiment, the tubular spacer 13 is formed with the cutout portion 13a for breaking the outer wall. Therefore, the gap between the cutout portions 13a is widened or narrowed to form a tubular shape. The inner diameter of the spacer 13 is likely to change.

In this embodiment, the cutout portion 13a is formed.
Although the rubber band 11 can be easily inserted into the tubular spacer 13 due to the presence of the tubular spacer 13, the tubular spacer 13 can be easily assembled after being assembled as compared with the elasticity of the rubber band 11.
If the rigidity is low, the elasticity of the rubber band 11 may cause the gap between the cutout portions 13a to be too wide, and the rubber band 11 may easily come off from the tubular spacer 13.

Therefore, a tubular spacer 13 made of a material having a relatively high rigidity is used. Accordingly, even if an external force is applied to the tubular spacer 13 due to the elasticity of the rubber band 11, the cutout portion 13a does not expand more than necessary. Therefore, it is possible to prevent the inner diameter of the tubular spacer 13 from increasing more than necessary. As a result, the combined state of the rubber band 11 and the tubular spacer 13 can be stabilized similarly to the correction assisting tool 10 in the first embodiment.

The material having a relatively higher rigidity than the rubber band 11 is not particularly limited as long as the width of the cutout 13a is not too wide when the rubber band 11 is combined. Generally, general plastic materials can be preferably used.

In this embodiment, as shown in FIGS. 9 (b) and 10 (c), the rubber band 11 has a notch in the width direction of the rubber band 11 (the band line F). Approximately 9 with respect to the diametrical direction passing through the portion 13a (diameter line E above)
An example in which the tubular spacer 13 is combined so as to have an angle of about 0 ° has been described, but it goes without saying that the present invention is not limited to this.

That is, in the correction assisting tool 20 according to the present embodiment, the end of the rubber band 11 is cut out in the state where the tubular spacer 13 is combined with the rubber band 11.
If the rubber band 11 cannot be easily removed from the tubular spacer 13 without facing a, the diameter line E
The angle of the band line F with respect to is not limited to about 90 ° (substantially vertical).

[Third Embodiment] The third embodiment of the present invention will be described with reference to FIGS. 11 to 14.
It is as follows. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in the first or second embodiment are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment has basically the same configuration as the correction assisting tool of the first embodiment, but both ends of the tubular spacer are substantially parallel to each other, and the tubular spacer is 2 is different in that it is formed as an inclined surface that is inclined with respect to a direction substantially orthogonal to the longitudinal direction.

That is, in the correction assisting tool of the first embodiment, the shape of the tubular spacer viewed from the side has a rectangular shape when viewed as a projection (see FIGS. 3A to 3C). In the correction assisting tool according to the embodiment, the shape of the tubular spacer as seen from the side surface is a parallelogram when viewed as a projection view.

Specifically, as shown in FIG. 11 (a),
The correction assisting tool 30 according to the present embodiment also has almost the same configuration as that of the first embodiment, and similarly to the first embodiment, the inclined tubular spacer having the openings 14a at both ends (contact surfaces). (Tubular member) 14 and rubber band 11 are combined. However, as shown in FIG. 11B, the inclined tubular spacer 1 according to the present embodiment
No. 4 is in a state in which both ends (contact surfaces) are parallel to each other and inclined (inclined surface), and therefore the shape seen from the side is a parallelogram shape.

Therefore, when the correction assisting tool 30 according to the present embodiment is attached to the chopsticks 5, as shown in FIG. 12, there is a constant space between the chopsticks 5a and 5b fixed by the small ring 11a. Although the distance H is secured, the correction assisting tool 30 itself is in a state of being inclined between the chopsticks 5a and 5b.

When the chopstick 5 to which the correction assisting tool 30 is attached is grasped, as shown in FIG. 13, the inclined tubular spacer 14 is attached.
The direction of inclination of and the direction of placement of the thumb are substantially parallel. Here, as described in the first embodiment, the spacing member is
This is for defining the position of the thumb that abuts on the upper chopsticks 5a when gripping the chopsticks 5 to which the correction aid 30 is attached so as to avoid a state where excessive force is applied to the thumbs. Therefore, when the inclined tubular spacer 14 as in this embodiment is used, the inclined tubular spacer 14 and the arrangement direction of the thumb are substantially parallel to each other, and the position of the thumb can be more accurately defined by the correction assisting tool 30. You can

The tilt angle α in the tilted tubular spacer 14 shown in FIG. 11B depends on the size of the palm of the user and the chopsticks 5.
And the shape of the rubber band 11 as the elastic annular member, and the like, and are not particularly limited. However, in general, the inclination angle α is within the range of 5 ° or more and 20 ° or less (5 ° ≦ α
≦ 20 °) is preferably used. Within this angle range, the inclination direction of the correction assisting tool 30 substantially corresponds to the arrangement direction of the thumb for most users.

Regarding the manufacturing method of the inclined tubular spacer 14, the tubular spacer 12 described in the first embodiment is described.
The tubes as the source of the above may be cut obliquely so that both ends thereof are parallel to each other. Alternatively, the tubular spacer 12 itself may be prepared to be a little longer (longer than the specified length L), and the both ends may be cut obliquely so as to be parallel.

Further, in the present embodiment, an elastic annular member may be used in combination with the inclined tubular spacer 14 shown in FIG.
As shown in (a), the inclined rubber band 21 may be a parallelogram when the shape from the side surface is viewed as a projection. When the inclined rubber band 21 and the inclined tubular spacer 14 are combined, as shown in FIG. 14 (b), a small circular ring 21 a formed by the inclined rubber band 21.
Since the inclination direction of is substantially aligned with the inclination direction at both ends of the inclined tubular spacer 14, it is possible to further stabilize the inclined state of the inclined tubular spacer 14.
When the correction assisting tool 30 is gripped, the correction assisting tool 30 can be brought into a state along the placement of the thumb.

The inclination angle β of the inclined rubber band 21 is not particularly limited as long as it is substantially the same as the inclination angle α of the inclined tubular spacer 14 (α≈β). However, in the case of the inclined rubber band 21, since it can be largely deformed due to its flexibility and elasticity, it is not necessary to strictly adjust the inclination angle β to the inclination angle α, and as described above, the non-inclined rubber band 11 is also sufficiently suitable. Can be used.

The inclination of both ends described in the present embodiment is not limited to the tubular spacer (tubular member), but is also applied to other spacers (spacer holding member) having other shapes described later. It is possible to In that case, the vicinity of the small ring formed in the spacer is the contact surface of the gripped rods that are parallel to each other, and this contact surface is, as described above, the longitudinal direction of the spacer (in other words, It may be formed as an inclined surface that is inclined with respect to a direction substantially orthogonal to the direction in which the gripped bar is separated.

Alternatively, in order to define the position of the thumb, the contact surface is not made to be an inclined surface, but the shape of the spacer is changed to form an inclined surface for defining the position of the thumb on the side surface portion of the spacer. May be provided. Therefore, the spacer used in the present invention does not need to have a cross-section of almost the same shape as the tubular spacer.

[Fourth Embodiment] The fourth embodiment of the present invention will be described below with reference to FIG. The present invention is not limited to this.
Further, for convenience of explanation, the first, second, or third embodiment
The members having the same functions as the members used in 1) are designated by the same reference numerals and the description thereof is omitted.

The correction assisting tool according to the present embodiment has basically the same configuration as the correction assisting tool of the above-described first, second, or third embodiment, except that it is not a tubular spacer as a space holding member. The difference is that scissors-shaped spacers (scissors-shaped members) are used.

Specifically, as shown in FIG.
The correction assisting tool 40 according to the present embodiment basically has the same configuration as that of the first to third embodiments, and the scissors-like spacers 15 and the rubber band 1 serving as the spacing members.
It consists of 1 combination.

The scissors-shaped spacer 15 is shown in FIG.
As shown in (b), a pair of flat plates 15 is formed from the base surface 15b.
The a and 15a are erected at a predetermined interval, and a rubber band 11 as an elastic ring member is sandwiched between the flat plates 15a and 15a. Further, when the rubber band 11 is sandwiched, small circular rings 11a, 11a are formed at both ends (contact surfaces).

That is, in the first to third embodiments, the rubber band 11 is inserted into the hollow portion of the tubular spacer so as to be combined. However, in the present embodiment, the scissor-like spacer 15 is provided between the flat plates 15a and 15a. The rubber band 11 is sandwiched and combined.

In the scissor-shaped spacer 15 having the above structure, the rubber band 11 is sandwiched between the pair of flat plates 15a, 15a as shown in FIG. 15 (a). Flat plates 15a, 15 of the spacer 15
The scissor-like spacer 15 and the rubber band 1 are antagonized by the pinching force at a and the elasticity of the rubber band 11.
The combined state with 1 is stabilized. Moreover, unlike the tubular spacer according to the first embodiment, the rubber band 11 is not inserted into the hollow portion, but unlike the tubular spacer according to the second embodiment, the rubber band is inserted through the gap between the flat plates 15a and 15a. Since 11 is inserted, the correction aid 40 can be obtained by easily combining the rubber bands 11.

As the scissors-like spacer 15 in the present embodiment, the rubber band 11 is sandwiched so as to form a pair of small circular rings 11a, 11a, and the chopsticks 5a, 5b are inserted.
The spacer is not particularly limited as long as it has a shape as a spacer that can maintain a constant interval H between them. In the scissors-shaped spacer 15 described above, the flat plate 15a.
Although there is a certain distance between the 5a, for example, various clip-shaped members in which the plate-shaped portions corresponding to the pair of flat plates 15a and 15a are completely closed at their tips are used. May be.

[Fifth Embodiment] The fifth embodiment of the present invention will be described below with reference to FIG. The present invention is not limited to this.
Further, for convenience of description, members having the same functions as those used in any of the first to fourth embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment has basically the same configuration as the correction assisting tools according to the first to fourth embodiments, but an elastic circle such as a rubber band is used as the spacing member. Instead of using tubular spacers or scissors-shaped spacers that are independent of the ring member, block-shaped fixed spacers (lump members) that are almost completely integrated with the rubber band are used.

Specifically, as shown in FIG. 16, in the correction assisting tool 50 according to the present embodiment, the fixing spacer 16 is arranged between the rubber bands 11, and the inner peripheral surface of the rubber band 11 is arranged. In contrast, it is completely fixed. At this time, the fixing position of the fixing spacer 16 is in the vicinity of the central portion in the longitudinal direction of the rubber band 11 so that the small circular rings 11a are formed at both ends. A contact surface 16a is formed at both ends of the fixed spacer 16 (portions where the small circular rings 11a and 11a are formed).

In this structure, the spacing member (the tubular spacer 12 or the like) is not arranged outside the elastic annular member (rubber band 11), but the spacing member is maintained inside the elastic annular member (rubber band 11). A member (fixed spacer 16) is arranged. Therefore, although the elastic annular member and the spacing member are not separable from each other as in each of the above-described embodiments, they are completely fixed, and thus the correction assisting tool 50 is provided.
The stability as can be improved.

The fixed spacer 16 is not particularly limited, and is fixed inside the rubber band 11 to form a small circular ring 11a, and a pair of chopsticks 5 are attached to the small circular ring 11a. It is only necessary that the pair of chopsticks 5 have strength enough to secure a constant distance H between them. The method for fixing the fixed spacer 16 is not particularly limited, but normally, the fixed spacer 16 is fixed with various adhesives.
The method of sticking the rubber on the inner peripheral surface of the rubber band 11 is preferably used.

The preferable range of the length of the fixed spacer 16 in this embodiment is the same as the length L of the tubular spacer 12 described in the first embodiment, and the description thereof will be omitted. In addition, the fixed spacer 16
The thickness of the chopsticks is not particularly limited as long as it can be formed by the small circular ring 11a described in the first embodiment. In other words, it can be appropriately set according to the outer diameter of the chopsticks 5. Not something. Further, the width of the fixed spacer 16 is not particularly limited as long as it can secure the above-mentioned interval H and does not affect the grip of the chopsticks 5 attached to the chopsticks 5. It is preferable to set the width according to W because the configuration of the correction assisting tool 50 as a whole is stabilized.

Therefore, as a concrete example of the fixed spacer 16, it is sufficient that the fixed spacer 16 has such a strength that the fixed interval H can be secured in the state of being attached to the chopsticks 5. It is preferable that the member is one lump (block-shaped) member (lump-shaped member). For example, commercially available erasers and the like are inexpensive and have a block shape having sufficient strength, so that the orthodontic aid according to the present embodiment can be obtained only by adhering this to the rubber band 11 with a known adhesive. You can

[Sixth Embodiment] The sixth embodiment of the present invention will be described with reference to FIGS. 17 to 20.
It is as follows. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in any of the first to fifth embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment basically uses a substantially pipe-shaped spacing member, similarly to the correction assisting tools according to the first to fourth embodiments. The form is different in that a coil-shaped member, that is, a coil-shaped spacer is used as the spacing member.

Specifically, as shown in FIG. 17, the correction assisting tool 60 according to the present embodiment has a coil-shaped spacer 1
7 is combined with a rubber band 11. This coil-shaped spacer 17 has openings 17b at both ends similarly to the tubular spacer 12 described in the first embodiment and the like.
The tubular spacer 12 has a length and an inner diameter.
Similar to, but not in the form of a series of side walls like the tubular spacer 12, but in the form of a coil formed by winding a linear member.

The coil-shaped spacer 17 has a shape in which a linear member is wound to form a large number of wound portions 17a. Therefore, when used as a spacing member, each of the winding portions 17a, 17a
Although it is possible to completely bond the gaps with an adhesive or the like to have a shape substantially similar to that of the tubular spacer 12, as shown in FIG. Winding part 17a by pulling in the K direction)
The space between 17a may be widened and stretched.

It is assumed that the orthodontic assisting tool 60 including the combination of the coil-shaped spacer 17 and the rubber band 11 is attached to the chopsticks 5. At this time, as shown in FIG. 19, as in the first embodiment, the rubber band 11 has the chopsticks 5a.
The coiled spacers 17 arranged between the chopsticks 5a and 5b oppose the contraction force of the rubber band 11, while the contraction force of sticking the 5b to each other is shown (arrow P in the figure). Then, a certain space H is secured between the chopsticks 5. Therefore, the chopsticks 5a and 5b are fixed so as to be sandwiched between the end of the coil-shaped spacer 17 and the small circular ring 11a (a part of the rubber band 11).

Therefore, even with the coil-shaped spacer 17 which is not adhered in the wound state, the wound portions 17a are brought into close contact with each other due to the contraction of the rubber band 11. As a result, it becomes a stable spacing member substantially like the tubular spacer.

Moreover, as shown in FIG. 20, when the chopstick 5 to which the correction assisting tool 60 according to the present embodiment is attached is grasped, the coil-shaped spacer 17 has the rubber band 1
Although it is a stable spacing member due to the contraction action of 1,
Since the winding portions 17a are not adhered to each other, it is possible to shift the winding portions 17a ... According to the arrangement of the thumb when gripped. As a result, like the inclined tubular spacer described in the third embodiment, the coiled spacer 17 can be placed in a state along the placement of the thumb, and the position of the thumb can be more reliably defined. . In particular, when the inclined rubber band 11 is used, it is possible to stabilize the state in which the wound portions 17a of the coil spacer 17 are displaced along the inclination direction.

The linear member serving as the coil-shaped spacer 17 is not particularly limited, and a coil-shaped member made of plastic or the like can be preferably used. Also, the material of the coil-shaped spacer 17 is not particularly limited, and it is crushed by the force applied inward in the longitudinal direction by the contraction action of the rubber band 11 (in the direction of arrow P in FIG. 19) with the chopsticks 5 attached. As a space holding member, a fixed space H is provided between the chopsticks 5.
Any material that can secure

[Embodiment 7] The following description will discuss Embodiment 7 of the present invention with reference to FIG. The present invention is not limited to this.
Further, for convenience of description, members having the same functions as those used in any of the first to sixth embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment has a small circular ring 1 in addition to the correction assisting tools according to the first to sixth embodiments.
The structure further includes a small ring inner diameter holding member for holding the inner diameter of 1a at a predetermined value.

Specifically, for example, as shown in FIG. 21 (a), a correction assisting tool 10 comprising a combination of the tubular spacer 12 and the rubber band 11 in the first embodiment.
In addition, by combining these, the small ring 11a
21B, a short pipe 22 having a cutout 22a as shown in FIG. 21B is fitted into the rubber band 11 forming two small circular rings 11a. . That is, the short pipe 22 corresponds to the small circular inner diameter holding member.

The short pipe 22 is provided in the second embodiment.
21 (b), the cylindrical spacer 13 has a notch 22a formed in a part of its cylindrical portion.
As shown in, the cross section has a shape like an alphabet "C".

In the correction assisting tool 10 according to the present embodiment, the small pipes 11a are fitted into the respective small circular rings 11a so that the small circular rings 11a have a substantially perfect circular shape (substantially a perfect circular shape). Be held). Therefore, the chopsticks 5a and 5b can be easily attached to the small ring 11a. Furthermore, since the short pipe 22 is formed with the cutout portion 22a, it is possible to change the inner diameter of the short pipe 22 by enlarging or reducing the interval between the cutout portions 22a. Therefore, the outer diameter of the chopsticks 5 that can be worn extends over a wide range, like the small ring 11a of the correction assisting tool 10 in the first embodiment, and as a result, the chopsticks 5 can be worn more easily. At the same time, the versatility of the correction assisting tool 10 according to the present embodiment can be expanded.

The length of the short pipe 22 is not particularly limited as long as it can hold the small circular ring 11a in a substantially perfect circular shape. Normally, as shown in FIG. 21 (c), the rubber band 11 is slightly longer than the band width W (for example, about 1 m from each end of the small ring 11a).
If it is set to a length such that it protrudes about m), a small ring 11
This is preferable because the ability to hold a in a substantially perfect circle can be sufficiently exerted, and the small ring 11a can be easily fitted and removed.

The material of the short pipe 22 is not particularly limited, but it is preferable that the short pipe 22 has a rigidity that can endure the contraction action of the rubber band 11. As a result, the ability to hold the small circular ring 11a in a substantially perfect circle can be further improved.

In the present embodiment, the short pipe 22 is used as the small circular ring diameter holding member, but the present invention is not limited to this, and the small circular ring 11a can be fitted into the small circular ring 11a.
As long as it can be held in a substantially annular shape. For example, the coil-shaped member described in the sixth embodiment can be used. Further, the small ring diameter holding member does not necessarily have to hold the small ring 11a in an annular shape, but may be a member that holds the small ring 11a in an elliptical or quadrangular shape.

As described above, the correction assisting tool according to the present invention is
In addition to the elastic circular ring member and the spacing member, a small circular ring inner diameter holding member may be further provided. In the present invention, the correction assisting tool can be easily assembled by combining the above-mentioned three types of members that can be obtained as a commercially available product at low cost. Moreover, since each member can be easily combined, it becomes possible for the user to sell each member as a kit, and the orthodontic assisting device that can exhibit a more appropriate holding manner is preferred by the user. Can be created according to.

21 (a) and 21 (c), the short pipe 22 (see FIG. 21 (b)) as the small annular diameter holding member in the present embodiment is provided with the correction assist according to the first embodiment. Although the example applied to the tool 10 is shown, of course, the present invention is not limited to this, and the correction assisting tools 20, 30, 4 according to any one of the second to sixth embodiments.
It goes without saying that it can be applied to 0, 50, or 60, and can be applied to all orthodontic appliances within the scope of the present invention.

Further, in the present invention, all of the tubular spacer 12, the rubber band 11 and the short pipe 22 may be covered by a commercially available rubber tube. That is, a rubber tube having a large diameter is used as the rubber band 11, a rubber tube having a small diameter is used as the tubular spacer 12 and the short pipe 22, and the cutout portion 22a is appropriately formed in the short pipe 22 to achieve the present embodiment. The correction aid 10 can be obtained. In this case, the small-diameter rubber tube has a large rigidity due to its small diameter, and does not expand or contract as much as a large-diameter rubber tube. Can be considered to have.

[Eighth Embodiment] An eighth embodiment of the present invention will be described with reference to FIGS. 22 and 23.
It is as follows. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in any of the first to seventh embodiments are designated by the same reference numerals, and the description thereof will be omitted.

The correction assisting tool according to the present embodiment is different from the correction assisting tools of the first to seventh embodiments in that it is not an elastic annular member such as the rubber band 11 but an annular member having no elasticity. On the other hand, as the spacing member, a stretchable member is used. That is, as compared with the first to seventh embodiments, the roles of the annular member and the spacing member are reversed.

Specifically, as shown in FIGS. 22 (a) and 22 (b), a vinyl band 31 is used as an annular member, and a plurality of continuous pleats are provided as an interval holding member to provide elasticity. It is possible to use a bellows-shaped spacer (bellows-shaped member) 18 that is expandable and contractible. When these are combined in the same manner as in the first embodiment to form the correction assisting tool 70 according to the present embodiment, the vinyl bands 31 protrude from the openings 18a, 18a at both ends (contact surfaces) of the bellows-shaped spacer 18, respectively. To form a small circular ring 31a, and has almost the same configuration as the correction assisting tool 10 to 60 of each of the above-described embodiments.

However, as shown in FIG. 23, when the correction aid 70 is attached to the chopsticks 5, unlike the first embodiment and the like, the vinyl band 31 hardly shrinks or stretches (having shape stability). In contrast, in the bellows-shaped spacer 18 into which the vinyl band 31 is inserted in the hollow portion, both chopsticks 5a.
It exerts a force to separate the 5b from each other. As a result, each of the chopsticks 5a and 5b has a small ring 31a formed by the vinyl band 31.
And the end portion of the bellows-shaped spacer 18 that acts to press against the small circular ring 31a.

In this state, the pair of chopsticks 5 are fixedly supported by the small circular ring 31a formed of the vinyl band 31. The small circular ring 31a connects the vinyl band 31 to the bellows-shaped spacer 18. Since the end piece is closed, the end piece moves due to the elasticity of the bellows-shaped spacer 18, so that the chopsticks 5 can be easily moved like the small circular ring 11a of the rubber band 11 in the first embodiment. Will be fixed as.

That is, in the present embodiment, the vinyl band 31 secures a constant space H between the chopsticks 5a and 5b, while the bellows-shaped spacer 18 expands in the longitudinal direction (in the direction of arrow J). The small circular ring 31a holds the chopstick 5a or the chopstick 5b in a movable state. As a result, it is possible to exhibit the same action as that of the correction assisting tools 10 to 60 according to each of the above-described embodiments, and it is possible to easily, surely and efficiently learn how to properly hold the chopsticks 5. .

The material of the bellows-shaped spacer 18 is not particularly limited as long as it exhibits elasticity and has strength enough to secure a constant distance H between the chopsticks 5a and 5b. Instead, commercially available tubes having a bellows shape can be preferably used. In addition, since the inner diameter of the bellows-shaped spacer 18 is substantially the same as that of the tubular spacer 12 described in the first embodiment, the description thereof will be omitted.

However, regarding the length of the bellows-shaped spacer 18, since the bellows-shaped spacer 18 has elasticity, the length corresponding to the above-mentioned constant interval H in a state where the bellows-shaped spacer 18 exhibits elasticity and is stretched to some extent. It must be L.

As described above, in the correction assisting tool according to the present invention, one of the annular member and the spacing member can be expanded and contracted, and the other can secure a constant spacing. Good. As a result, when the chopsticks are held so as to be sandwiched between the ends of the spacing member and the small circular ring formed by the circular ring member, one of them has elasticity and can be expanded and contracted. The chopsticks can be easily moved by securely fixing them and applying external force with fingers.

Therefore, as the spacing member,
For example, the coil-shaped spacer described in the sixth embodiment can be used. That is, in the sixth embodiment,
Although the coil-shaped spacer is stretchable, it does not have elasticity, but by giving elasticity, it is possible to exhibit the same function as that of the bellows-shaped spacer.

However, in this case, also in the coil-shaped spacer, the length L is not secured in the state where all the wound portions are in close contact with each other, but like the bellows-shaped spacer,
It is necessary that the length L be ensured in a state of being stretched to some extent due to elasticity (a state in which the wound portions are separated from each other to some extent).

[Ninth Embodiment] A ninth embodiment of the present invention will be described with reference to FIGS. 24 to 27.
It is as follows. The present invention is not limited to this. Further, for convenience of explanation, members having the same functions as those used in any of the first to eighth embodiments are designated by the same reference numerals, and the description thereof will be omitted.

In the first to seventh embodiments, an example in which chopsticks are used as the held bar is given, but in the present embodiment, an example in which a writing instrument is used as the held bar will be described.

As a general theory, in the correction of how to hold a grasped rod, it is said that if the chopsticks can be properly grasped, a writing instrument such as a pencil can be properly grasped. However, investigations by the present inventor have revealed that this general theory is false.

That is, although the chopsticks and the writing implement have the same basic finger arrangement and the same force, the chopsticks consist of two rods, whereas the writing implement consists of one rod. ,
If the user cannot grasp the chopsticks accurately,
As a result, the chopsticks and the writing instrument are recognized as different holding methods, and even if the chopsticks can be accurately grasped, the writing instrument is fixed by being grasped with the wrong holding method.
In fact, under the present circumstances, even an adult who can hold chopsticks properly can often not hold the writing instrument properly.

Therefore, it is practically impossible to use the conventional general orthodontic holding aids for chopsticks or the orienting orthodontic chopsticks for correction of how to hold the writing implement (however, according to the present inventor. The orthodontic assisting device of the above-mentioned Japanese Patent Laid-Open No. 11-007236, which was invented, can be applied to both chopsticks and writing instruments).

On the other hand, in the present invention, as shown in FIG. 24, for example, the correction assisting tool 1 in the first embodiment is used.
For 0, a writing tool, for example, a pencil 6 is attached to one small circular ring 11a, and some rod-shaped member 7 is attached to the other small circular ring 11a. .

The rod-shaped member 7 to be mounted on the other small circular ring 11a is not particularly limited, and may be an unused pencil which has not been used yet and whose core is not exposed, or a work tool. Various plastic sticks used for, or disposable chopsticks are used. However, this rod-shaped member 7
It is preferable that the length is approximately the same as the length of the writing instrument (pencil 6) or the length according to the size of the palm of the user.

When the pencil 6 with the correction assisting tool 10 attached is gripped, as shown in FIG. 25, the tubular spacer 12 secures a constant distance H between the pencil 6 and the rod-shaped member 7 to form a rod-shaped member. The base of the thumb is pressed by the member 7, and the tip of the thumb comes into light contact with the pencil 6.

The correct way of holding the writing instrument is basically the same as the correct way of holding the chopsticks, and the main elements that move the writing instrument are the index finger and the middle finger, and the thumb is light enough to regulate the position of the writing instrument. It only has to abut. Therefore, the correction assisting tool according to the present invention is used not only for the chopsticks but also for correcting the holding manner of the writing tool by mounting the writing tool on one of the small circles and mounting a rod-shaped member on the other small circle. It becomes possible.

Here, in the present embodiment, as shown in FIG. 26, at least the small circular ring 11a on the side on which the writing tool (here, the pencil 6) is mounted has the small circular ring diameter described in the seventh embodiment. It is more preferable to fit a short pipe 22 (see FIG. 21B) as a holding member. When the outer diameters of the chopsticks and the writing instrument are compared with each other, the outer diameter of the writing instrument generally tends to be larger. Therefore, the writing instrument is more difficult to attach to the small circular ring 11a than the chopsticks. Therefore, if the short pipe 22 is fitted in advance to the small circular ring 11a in accordance with the outer diameter of the writing instrument, the writing instrument can be more easily attached.

Needless to say, the short pipe 22 may be fitted into the small circular ring 11a on the side where the rod-shaped member 7 is mounted. However, as the rod-shaped member 7, as described above, for example, disposable chopsticks or the like may be cut to an appropriate length. Since it may be used, the short pipe 22 does not necessarily have to be fitted.

Further, in the present embodiment, as shown in FIG. 27, the writing tool (pencil 6) is attached to the small circular ring 11a in which the short pipe 22 is fitted in order to further stabilize the attachment state. And a small ring 11a in a writing instrument
The stoppers 26 may be attached at the front and rear positions. In the small circular ring 11a into which the short pipe 22 is fitted, a shape such as a substantially perfect circle is secured so that the writing instrument can be easily attached, but the fact that it is easily attached also makes it easy to remove it. Therefore, by using the stopper 26,
The wearing state of the writing instrument can be further stabilized.

The stopper 26 is not particularly limited, but for example, a commercially available tubular non-slip member (molded with a sponge-like material or a rubber material) is cut into an appropriate length and used. be able to.

The above-described correction assisting tool according to the present invention can exhibit the same functions as those of the conventional holding-correction-holding-rods and holding-correction-assisting-tools (molded products by mold) described above, and in particular, a rubber band or the like Due to the elasticity of the above, it is possible to simultaneously exhibit the contradictory functions that cannot be obtained with the above-mentioned molded product, in particular, the flexibility of freely moving a pair of grasped rods and the fixing property of firmly connecting the grasped rods. It is possible. However, in order to more surely position each finger in the correct holding manner of the grasped rod, it is more preferable to use the above-mentioned conventional grasping graspable rod for grasping or a grasping correction assisting tool by the present inventor.

[0181]

Industrial Applicability As described above, the gripping rod correction assisting tool according to the present invention has an annular member and a shape in which the annular member can be combined, and at least one of them has a shape. And a spacing member that holds a constant spacing between a pair of rod-shaped members that are gripped rods, the spacing member,
In a state where the above annular members are combined, the annular members protrude from positions facing each other, and the protruding annular members form a pair of small annular rings to which the rod-shaped members can be attached respectively. In addition, only one of the annular member and the spacing member has elasticity and can expand and contract.

In the above structure, when the grasped rod to which the correction aid is attached is grasped, the thumb, which is apt to receive excessive force, only comes into light contact with it naturally, and the index finger and the middle finger act as the main body for moving the grasped rod. So that it makes sufficient contact. Therefore, the gripped rod can be easily moved. Moreover, the elasticity of the annular member or the spacing member allows the position of the gripped rod to easily return to its original position, and the gripped state does not shift. As a result, by using the correction assisting tool according to the present invention, it is possible to easily, surely and efficiently acquire the correct way to hold the chopsticks.

In addition, the above-mentioned structure has a very simple structure in that it can be formed only by combining generally available rubber bands and tubes. Therefore, there is an effect that the cost is further lower than that of the conventional correction assisting tool and, for example, the correction assisting tool according to the present invention can be used for free distribution.

In the correction assisting device for holding the gripped rod, the annular member is preferably an elastic annular member which has elasticity and is capable of expanding and contracting, and the elastic annular member is constant. More preferably, it is a strip-shaped rubber band having a width of.

In the above structure, the position of the grasped rod is easily returned to the original position by the spring action due to the elasticity of the elastic annular member. Therefore, if the corrective assisting tool according to the present invention is grasped in the correct way, the grasped rod is held. Even if the force applied to each finger is changed by using, the gripped state does not shift. As a result, there is an effect that it is possible to easily, surely, and efficiently learn how to hold the gripped rod correctly.

Moreover, if a rubber band is used as the elastic annular member, the rubber band having such a shape is sufficiently contained in a commercially available rubber band. Therefore, in producing the correction aid according to the present invention, it is not necessary to newly form a rubber band having a special inner diameter, and therefore, a mold used for extrusion molding of the rubber band is not special and is commonly used. Anything can be used. As a result, there is an effect that the cost of the correction aid can be further reduced.

In the correction assisting device for holding a grasped rod, the spacing member is a tubular member, and the annular member is inserted into the hollow portion of the tubular member and formed at both ends in a combined state. It is preferable that the pair of small circular rings be formed by the circular ring members protruding from the respective openings.

In the case of the above-mentioned structure, in the case of a tubular member, it is possible to easily realize a combined state in which a small circular ring is formed simply by inserting the elastic circular ring member in the hollow portion.
As the tubular member, since generally commercially available tubes can be preferably used, the cost can be further reduced as compared with the conventional correction assisting tool. As a result, there is an effect that the correction aid according to the present invention can be made inexpensive to the extent that it can be used for free delivery.

In the correction assisting device for holding the gripped rod, the tubular member has a linear notch formed so as to be connected to the hollow portion along the longitudinal direction of the outer peripheral surface thereof. Good.

With the above structure, the elastic annular member can be easily inserted into the hollow portion through the cutout portion and incorporated therein. Furthermore, the assembled state can be sufficiently stabilized simply by rotating the assembled elastic annular member, and if the elastic annular member is rotated so as to face the notch, the elastic annular member will be rotated. It has the effect of being easily removable.

Further, in the above-mentioned grasping rod holding correction assisting tool, the spacing member is a scissors-like member capable of sandwiching the annular members so as to form the pair of small annular rings. May be.

In the above structure, for example, if the scissors-like member sandwiches the elastic annular member between the pair of flat plates, the sandwiching force of each flat plate and the elasticity of the elastic annular member antagonize each other. Thus, the combined state of the scissors-like member and the elastic annular member is stabilized, and an effect of being able to obtain a correction assisting tool similar to the above tubular members can be obtained. In addition, since the combined state can be realized only by sandwiching the elastic annular member between the sandwiching parts such as a pair of flat plates, the effect of being able to combine the correction aids more easily is also obtained.

Further, in the above-described holding-correction aid for holding a gripped rod, the spacing member is a lump member fixed inside the annular member so as to form the pair of small annular rings. May be.

In the above construction, the block-shaped member serving as the spacing member is arranged and fixed inside the elastic annular member. Therefore, although the elastic annular member and the spacing member are not separable from each other, since they are completely fixed, the stability of the correction assisting tool can be further improved.

In the correction assisting device for holding the gripped rod, or in the state where the spacing member is a coil-shaped member and the annular member is inserted in the hollow portion of the coil-shaped member and combined. The pair of small circular rings may be formed by circular ring members protruding from the openings formed at both ends.

In the above structure, if the correction assisting tool in which the coil-shaped member and the elastic annular member are combined is used, the elasticity of the elastic annular member and the coil-shaped member can be obtained with the grasped rod attached to the small annular ring. With the shape stability of the wound portion of the coil in close contact with each other, the gripped rod is sandwiched between the coil-shaped member and the elastic annular member to be stabilized, and a certain distance is secured between the gripped rods. be able to. Therefore, it is possible to obtain the same correction assisting tool as the tubular member.

Moreover, for example, when holding a chopstick to which a correction aid using the coiled member is attached, the coiled member becomes a stable spacing member due to the contracting action of the elastic annular member, while Since the winding parts are not adhered to each other, it is possible to shift the winding parts according to the position of the thumb when gripped. As a result, there is an effect that the coil-shaped member can be brought into a state along the placement of the thumb, and the position of the thumb can be more reliably defined.

[0198] In the correction assisting device for holding the gripped rod, the inner diameter of the small circular ring that changes according to the outer diameter of the gripped rod to be mounted is fixed while being fitted in the small circular ring. It may include a small ring inner diameter holding member for holding.

In the above structure, if the small ring inner diameter holding member is fitted into the small ring, the shape of the small ring can be held in a substantially complete ring shape (substantially perfect circular shape). Therefore, there is an effect that the gripped rod can be easily attached to the small ring.

In the correction assisting device for holding the gripped rod, the spacing member is a bellows member having a plurality of continuous pleats, which is elastic and expandable. Even if the pair of small circular rings are formed by the circular ring members protruding from the openings formed at both ends in a state where the circular ring members are inserted and combined in the hollow portion of the member. Good.

In the above structure, the annular member hardly expands or contracts, but the bellows-like member, which is the spacing member, has elasticity and elasticity. Therefore, the bellows-like member separates the gripped rods from each other to maintain a certain distance, and the separation force of the bellows-shaped member and the annular member having shape stability hold the attached state of the gripped rods. Can be stabilized. As a result, there is an effect that it is possible to obtain a correction assisting tool having the same function as that of the correction assisting tool using the tubular member.

In the correction assisting device for holding the gripped rod, the contact surfaces of the gripped rods which are substantially parallel to each other are formed in the vicinity of the spacing member where the small ring is formed. It is preferable that the surface is formed as an inclined surface that is inclined with respect to a direction substantially orthogonal to the separating direction of the gripped rod.

In the above structure, when the correction assisting tool which is a combination of the spacing member having the inclined surface and the annular member is attached to the gripped rod, the correction assisting tool (spacing holding member) moves between the gripped rods ( Alternatively, it is inclined between the gripped rod and the rod-shaped member). Therefore, when the gripping rod to which such a correction aid is attached is gripped, the inclination direction of the spacing member and the arrangement direction of the thumb are substantially parallel to each other, so that the position of the thumb can be more accurately defined by the correction aid. can do. Therefore, there is an effect that a more correct holding method can be realized.

In the present invention, chopsticks are preferably used as the grasped stick. That is, since a pair of two chopsticks is used, it is suitable as a grasped rod that can be attached to a pair of small circular rings. However, in the pair of small rings,
It suffices that the gripping rod is attached to either one, and therefore one gripping rod to be used, for example, a writing implement is attached to one of the rods, and some rod shape having a length that does not hinder the grasping of the writing implement on the other By simply attaching the member, it can be used for correcting how to hold the writing instrument. Therefore, the correction aid according to the present invention is extremely versatile.
