Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporter for preventing ankle inversion sprain.

[0002]

2. Description of the Related Art Ankle inversion sprain occurs when the ankle Fn is twisted as shown in FIG. That is, this occurs when the bottom of the foot is forcibly twisted strongly inward with the ankle Fn stretched. A protector when the ankle Fn is damaged by such a varus sprain is disclosed in Japanese Utility Model Publication No. 7-24088.

On the other hand, the ankle inversion sprain prevention tool is attached at the time of playing to prevent the inversion sprain in advance, and for example, those shown in FIGS. 8 and 9 are commercially available. As shown in FIG. 8, in this conventional preventive tool, a substantially cylindrical tubular member 100 having elasticity for tightening an ankle, a plate-shaped member 101 made of a resin plate, and an upper portion of the plate-shaped member 101 are tubular. Tape-shaped band (fixing member) fixed to the belt-shaped member 100
It is equipped with 102. The preventive device prevents the varus sprain (rotation in the direction of arrow A) by the taping effect of the tightening force of the tubular member 100 and the plate-shaped member 101 acting like a protruding rod. Further, a band-shaped non-stretchable tape member 103 shown in FIG. 9 is sewn to the tubular member 100 on the outer side of the foot of the tubular member 100, and the material on the outer side of the tubular member 100 extends vertically. By preventing this, the joint action with the plate-like member 101 is intended to further prevent the inversion sprain.

[0004]

However, in the prior art, although the tape member 103 can prevent the outer material itself of the tubular member 100 from vertically extending, the tape member 103 is arranged along the outer ankle. And therefore,
Since the tape member 103 bends up and down, that is, since there is play in the tape member 103, even if the tape member 103 rotates in the direction of arrow A, the tape member 103 that has meandered only changes to a linear shape. Cannot be sufficiently suppressed from being twisted in the direction of arrow A. Therefore, an object of the present invention is to provide an ankle varus anti-twisting device having a high effect of preventing varus spraining.

[0005]

In order to achieve the above object, the present invention provides a tape which is connected to a lower portion of a plate member or a sole of a tubular member and which can be bonded to the surface of the tubular member. A member is provided, and the tape member is set to rotate from the sole to the outside of the foot of the tubular member.

In the present invention, while pulling the tape member, the tape member is rotated to the outside of the foot of the tubular member to bond the tape member to the surface of the tubular member. When mounting this tape member, the tape member tightens the tubular member from the outside, so that if the ankle is twisted inward, the sole of the foot does not rotate inward, as shown by arrow B in FIG. , Drag that pulls the outside of the foot upwards works.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show the first embodiment, and FIGS. 1 and 2 show a wearing state of the present preventive tool. The present preventive tool includes a tubular member 1 shown in FIG. 3, a plate member 2 shown in FIG. 4, a fixing band (member) 3 and a tape member 4.

The tubular member 1 shown in FIG. 3 (a) is formed in a substantially tubular shape, and has a front hole 10 for projecting the stepped portion Fa and a rear hole 11 for projecting the heel Fb. And an upper hole 12 for inserting a foot,
And, with a part of the heel Fb protruding, it covers the heel Fc and part of the sole of the foot. As shown in the enlarged cross-sectional view of FIG. 3B, the tubular member 1 includes an intermediate sponge rubber layer 13, an elastic cloth layer 14 inside the sponge rubber layer 13, and a female outside the sponge rubber layer 13. The hook-and-loop fastener layer 15 and the hook-and-loop fastener layer 15 are laminated, and have elasticity for tightening the ankle Fn in the state of FIG. The tubular member 1 is provided with an opening / closing portion 16 for widening the upper hole 12 so that the tubular member 1 can be attached to a foot, and the opening / closing portion 16 is provided with a male fastener on the inner surface. The joint portion 17 of FIG. 3 is sewn, the joint portion 17 is superposed on the female fastener layer 15 (FIG. 3B) which is the surface of the tubular member 1, and the opening / closing portion 16 is closed.

The plate-like member 2 shown in FIG. 1 covers the inside ankle Fc and is formed to be long in the up-down direction, and when the ankle Fn tries to rotate in the direction of arrow A, it functions like a stick. The plate-shaped member 2 is made of, for example, a hard resin so that the plate-shaped member 2 functions as a protruding rod. In addition, the plate-shaped member 2 has its upper portion curved along the outer circumference of the foot, and has a maximum width W of 50 mm in the circumferential direction so as not to prevent the ankle Fn from bending in the front-back direction.
It is set to about 100 mm. The plate-shaped member 2 is
The part of the ankle Fc bulges slightly outward.

A pair of first slit-shaped holes 21 are provided in the upper part of the plate-shaped member 2, and a fixing band 3 which is long in the lateral direction is connected to each of the first slit-shaped holes 21. Has been done. As shown in FIGS. 4 and 5, the fixing band 3 has male fasteners over substantially the entire inner surface thereof. As shown in FIG. 1, the upper portion of the plate member 2 is attached to the ankle F.
Removably fixed above n.

A second slit-shaped hole 22, for example, is provided at the lower end of the plate member 2 to connect the base end 40 of the tape member 4. As shown in FIG. 4, the tape member 4 has a male surface fastener over substantially the entire inner surface thereof, and is formed in a substantially Y shape so that the front end portion 4 is formed.
1, 41 are bifurcated. That is, the tape member 4 extends from the base end portion 40 and extends along the sole of the foot as shown in FIGS. 1 and 2, and the first and second bifurcated parts of the sole 42. And the tightening tape portions 43 and 44. The tape member 4 is set to have such a length that it can be rotated from the sole of the foot to the inside of the tubular member 1 via the outside of the tubular member 1, as shown in FIG. for that reason,
The length L1 of the tip portion 41 of the tape member 4 in FIG. 4 is 6 cm to 11
The length L2 of the first and second fastening tape portions 43 and 44 is preferably about 15 cm to 25 cm, and the total length (L1 + L2) of the tape member 4 is preferably about cm.
Is preferably about 20 cm to 35 cm.

Next, a method for mounting the present preventive tool will be described. First, as shown in FIG. 3, after wearing the tubular member 1, the tubular member 1 is pulled while pulling the joint portion 17 in the circumferential direction.
The ankle Fn is fastened by the tubular member 1 by being joined to the surface of the and closing the opening / closing portion 16. Next, the sole 42 of the tape member 4 of FIG. 4 is joined to the sole of the tubular member 1 of FIG. 2, and then the first tightening tape 43 is attached to the outside of the step of the foot. 5 through the front of the outer ankle Fc, and further through the bending portion of the upper part of the instep Fd of the foot,
The upper surface of the first tightening tape portion 43 is joined to the surface of the tubular member 1 by rotating the upper surface of the first tightening tape portion 43. On the other hand, the second of FIG.
The tightening tape portion 44 of the
through the rear of c, and further through the Achilles tendon,
The upper surface of the second tightening tape portion 44 is joined to the surface of the tubular member 1 by rotating the upper part of the inner ankle Fc in FIG. When joining the first and second fastening tape portions 43 and 44, the fastening tape portions 43 and 44 are joined while being pulled, and tension is applied to the joined fastening tape portions 43 and 44. To do. After that, the plate member 2 is joined to the surface of the tubular member 1 as shown in FIG. 1 while pulling the plate member 2 upward slightly and pulling the fixing band 3 in the circumferential direction. After wearing this protective gear, wear shoes.

In the present preventive tool thus mounted, first, the tubular member 1 tightens the entire ankle, thereby preventing rotation of the sole of the foot. Further, the plate-like member 2 functions like a protruding rod, and prevents the sole of the foot from rotating inward.
Further, by pulling the tape member 4 of FIG. 2 which is separate from the tubular member 1 and joining it to the surface of the tubular member 1,
Since the tubular member 1 is tightened so as to be pulled upward from below, the sole of the foot is prevented from rotating inward. That is, when the sole of the foot tries to rotate inward, the inside of the foot contracts up and down and the outside of the foot extends up and down, but the plate-like member 2 of FIG. 1 prevents the inside of the foot from contracting up and down. At the same time, the tape member 4 prevents the outside of the foot from extending vertically. As described above, in the present preventive tool, the contraction preventing effect of the plate-shaped member 2 and the elongation preventing effect of the tape member 4 cooperate with each other to exert an extremely excellent anti-rotation force. improves.

In particular, in this embodiment, as shown in FIG. 2, the tape member 4 is bifurcated and the soles are pulled up from the bottom by the fastening tape portions 43 and 44 which are divided into front and rear. Since the ankle is tightened, the anti-stretch resistance is stable. Therefore, not only the effect of preventing the inversion sprain is further enhanced, but also the reliability of the prevention is improved.

Further, in this embodiment, since the length of the tape member 4 is set so as to reach the inside of the foot, the fixation force of the ankle and the drag force for preventing the elongation are increased, so that the effect of preventing the inversion sprain is further enhanced. .

However, in the present invention, it is not always necessary to form the tape member 4 into a forked shape, and it is not necessary to rotate the tape member 4 to the inside of the foot.

Further, the present preventive tool only needs to be able to apply a vertical pulling force to the tubular member 1 by the tape member 4.
Therefore, a part of the sole 42 of the tape member 4 of FIG. 4 may be sewn to the sole of the tubular member 1. Also,
The tape member 4 may be divided at the sole portion 42, and the divided sole portion 42 may be sewn to the sole portion of the tubular member 1.
That is, the tape member 4 may be connected not to the lower portion of the plate-shaped member 2 but to the sole portion of the tubular member 1.

By the way, since the plate-shaped member 101 of FIG. 8 has a long maximum width W at the upper part, the plate-shaped member 101 comes into contact with the front and rear upper parts of the ankle, which hinders play (exercise). On the other hand, in this embodiment, as shown in FIG.
Since the maximum width W is short, the plate member 2 does not interfere with play. Moreover, since the plate-shaped member 2 has a small curvature, the shape of the plate-shaped member 2 approaches a flat plate, so that the cost of the mold is also low.

While the plate-shaped member 2 needs to have a function of a protruding rod, the maximum width W is reduced, so that the plate-shaped member 2 tends to buckle up and down. The buckling of the plate member 2 can be prevented by increasing the Young's modulus of the plate member 2.

6 and 7 show a second embodiment. In the second embodiment, the slit-shaped hole 2 of the plate member 2 of FIG.
One fixing band 3 is inserted through the reference numerals 1 and 21, and a female fastener member 39 is sewn (or planted) to a portion of the fixing band 3 exposed on the surface side of the plate-like member 2. . As shown in FIG. 6, the first and second tightening tape portions 4
3, 44 are female fastener members 3 on the fixed band 3.
It is joined to 9. Other configurations are the same as those in the first embodiment, and the same portions or corresponding portions will be denoted by the same reference numerals and the description thereof will be omitted.

Further, in the connecting structure of the plate member 2 and the tape member 4, the tape member 4 may be directly sewn or adhered to the plate member 2. Further, instead of the fixing band 3, a male fastener may be provided on the back surface of the plate member 2 to fix the upper and lower parts of the plate member 2 to the tubular member 1. Also, the tape member 4
Does not necessarily need to have a male fastener on the entire surface thereof, and may have a structure that can be joined to the tubular member 1 by at least having a joining portion such as a male portion fastener 41 or the like. .

[0022]

As described above, according to the present invention,
In addition to the function of the plate-shaped member as a bar, the tape member that can be bonded to the surface of the tubular member is provided, so that the inside of the foot shrinks when the foot sole tries to rotate inward. In addition to the rigidity, the outside of the foot is prevented from stretching by the tensile force of the tape member. That is, the present preventer prevents the inward rotation of the foot by the cooperation of the plate-like member preventing the inner contraction of the foot and the tape member preventing the outer expansion of the foot. Therefore, the effect of preventing the inversion sprain is improved.

Further, if the tape member is set so as to rotate to the inner side via the outer side of the foot, the tensile (stretching prevention) resistance of the tape member is increased, so that the effect of preventing the inversion sprain is further improved.

If the tip of the tape member is bifurcated, the tape member can be wound around the ankle, and the balance of tensile (stretching) resistance is improved.
The effect of preventing inversion sprains is further enhanced.
