JP5221433B2 - Shock absorbing pad and knee / elbow supporter using this shock absorbing pad - Google Patents

Description

  The present invention relates to an impact absorbing pad that absorbs an impact on a knee or elbow suitable as a knee supporter or an elbow supporter, and a knee / elbow supporter using the impact absorbing pad.

  In sports, treatment, etc., a supporter attached to the elbow or knee joint is used. For example, Patent Document 1 discloses a knee joint supporter excellent in stretchability and sweating property. In this supporter, a knee pad piece in which an impact relaxation material for reducing an impact applied to a knee is attached to a main body made of a member excellent in stretchability and sweating property by stitching. Patent Document 2 discloses a knee supporter that keeps the knee warm and softens the impact from the outside. This supporter has a pile-woven fabric on the front side and a towel fabric that easily absorbs sweat or the like on the back side, and the main body is integrally formed by overlapping.

In the above knee joint and elbow joint, it is desirable that the shock absorbing pad can follow the movement. That is, it is desired that the shock absorbing pad can follow the movement of the knee or elbow when the knee or elbow is bent to project. Thereby, an elbow or a knee can be smoothly bent without a feeling of pressure from a shock absorption pad to the above-mentioned knee joint or an elbow joint.
However, with conventional supporters, supporters with a hole in the center or a donut-shaped pad are used as a device for the movement of the kneecap or elbow head (bone protrusion behind the elbow joint) protruding. Only a device for forming slits on the outer periphery has been devised. Note that Patent Document 3 discloses an impact absorbing pad having a trident cut in the center. However, Patent Document 3 is an impact absorbing pad that protects the collar portion.

By the way, in order to protect the knee head and elbow head of the elbow, it is necessary to be a pad that completely covers them. However, if the knee or elbow head or elbow head is completely covered, the knee or elbow head or elbow head is a body part that is bent 90 degrees or more, and the movement of the knee and elbow becomes cramped. . In addition, it is difficult for the knee / elbow pads to continue to cover the knee and elbow heads according to the movement of the knees and elbows.
The above Patent Document 3 is an impact absorbing pad that protects the buttocks and is not intended for knees and elbows. However, if applied to knees and elbows, the kneecap protrudes by bending the knees and elbows. When the knee protrudes beyond that, the knee will pop out, and in this state, there will be no member protecting the kneecap and the like. In addition, it is desirable to protect the knees and the like when returning, but in Patent Document 3 described above, the three-pronged incision that is fully opened protects the knees and the like so as to follow the movement of the kneecaps and the like. It is hard to think of something that moves.

  On the other hand, supporters for knees and elbows in which shock absorbing pads are stored include those in which thin plate-shaped shock absorbing pads are stored and knee / elbow supporters in which arc-shaped or donut-shaped shock absorbing pads are stitched. . However, in the case of an arc shape or a donut shape, although there is a cloth on the surface, it is not perfect as protection for knees and elbows. There is a problem that the movement of knees and elbows becomes cramped. That is, the shape of the pad does not change according to the movement of the knee or elbow, and there are problems such as loosening and excessive tightening. Note that many conventional knee / elbow supporters are manufactured and sold as separate knee supporters and elbow supporters. There seems to be a reason why it is difficult to use both joints even if they have the same joint movement, because there are differences in how they are moved, the range and thickness of movement.

  Therefore, an object of the present invention is to provide an impact absorbing pad that can always follow the movement of the knee or elbow protruding or returning while always covering the knee or elbow, and a knee / elbow using the impact absorbing pad. Is to provide supporters.

The impact absorbing pad according to claim 1 of the present invention is a notch penetrating in the thickness direction of the pad, and has a first notch portion formed in a predetermined shape so as to surround the knee and elbow of the knee and elbow. The first notch is provided with a non-notch portion in which one end and the other end of the first notch are provided without being cut at a predetermined interval, and the knee head and elbow head of the knee or elbow protrude and come into contact with each other. The inside of the cut portion is configured as a first movable portion that can move with the position of the non-cut portion as a fulcrum.
According to the present invention, for example, with respect to a movement in which the kneecap or elbow is protruded by bending the knee or elbow, the first movable portion inside the first notch has the position of the non-notch as a fulcrum. For the movement of opening and returning the kneecap to the original position, the movement of returning the first movable part protruding from the non-cut portion as a fulcrum is performed.

In the shock absorbing pad according to claim 2 of the present invention, the second cut portion is formed on the outer periphery of the first cut portion, and one end portion and the other end portion of the second cut portion are predetermined. A second movable portion having a non-cut portion provided at intervals, and the inner side of the second cut portion being movable with the position of the non-cut portion as a fulcrum when the knee and elbow heads of the knee and elbow protrude and contact It is comprised as follows.
According to the present invention, for example, when there is little movement of the kneecap when the knee is bent, only the inner arc-shaped cut opens, but for the movement of the larger kneecap, the outer arc It works to open the notch. On the other hand, similarly, when the movement of the kneecap returns to the original position, when the movement is small, only the inner arc-shaped cut is closed, and for the movement of the large kneecap protruding, the outer circle Closes arc-shaped cuts. And since the notches are arc-shaped, they match the shape of the kneecap and elbow head, and also match the movements of the kneecaps more than the triangular or quadrilateral notches for the movements of the multiple steps. Perform smooth operation.

The impact absorbing pad according to claim 3 of the present invention is characterized in that the first cut portion has an arc shape, and a concentric arc-shaped second cut portion is formed on the outer circumference of the arc shape. To do.
According to the present invention, since the cut has an arc shape, the movable portion is operated in accordance with the movement of the knee or elbow in accordance with the shape of the knee or elbow.

The impact absorbing pad according to claim 4 of the present invention is characterized in that a slit directed to the first or second cut portion is formed on the outer periphery of the pad.
According to this invention, the knee is bent by narrowing the slit gap toward the first or second cut portion or by attaching the slit gap to the knee / elbow supporter. For the movement of the kneecap protruding, the shock absorbing pad is bent and the bending of the first or second notch is facilitated by this bending.

The knee / elbow supporter according to claim 5 of the present invention is provided with a front pocket into which the shock absorbing pad according to any one of claims 1 to 4 is placed, and the movable part of the shock absorbing pad is connected to the supporter. It is characterized by covering the material cloth.
According to the present invention, when the shock absorbing pad is used by being inserted into the kneecap portion or the elbowcap portion of the knee / elbow supporter, the cloth on the surface side of the supporter is protruded according to the movement of the movable portion. The cloth on the surface side suppresses the movement of the movable part. That is, the movement of the movable part is made gentle, and the cloth on the surface side assists the return operation of the movable part to quickly return to the original state.

The knee / elbow supporter according to claim 6 of the present invention is provided with a front pocket into which the impact absorbing pad according to any one of claims 1 to 4 is placed, and the impact absorbing pad is substantially rectangular. The front pocket has a substantially rectangular shape that is slightly smaller than the shock absorbing pad, and the shock absorbing pad is placed in the slightly smaller front pocket.
According to the present invention, a curved / knee / elbow-shaped shape that fits the shape of the knee or elbow is obtained simply by placing the shock-absorbing pad in a substantially rectangular front pocket that is slightly smaller than the substantially square-shaped shock absorbing pad. Become a supporter. And, it is easier to form the curved shape of the shock absorbing pad and the shape of the front pocket than when it is put in other front side pockets such as round shape with other shock absorbing pads such as round shape. It becomes easy.

  According to the shock absorbing pad of the present invention, it follows the movement of protruding and returning according to the movement of the knee and elbow while protecting the kneecap and elbow head, so that it is like a conventional supporter or pad with holes provided. In addition, a situation in which a projection smaller than the hole hits the kneecap does not occur, and the kneecap and elbow head are always protected while ensuring the movement. In addition, by providing the cut portions of the shock absorbing pad in multiple stages, there is a possibility that the cut will be damaged if the movement of the movable part is too large with one cut. Since the range of each movement is set, excessive movement of the movable part is suppressed, and there is no possibility that the notch is damaged.

  Further, according to the knee / elbow supporter of the present invention, when the shock absorbing pad is used by being inserted into the knee head part or the elbow head part of the knee / elbow supporter, the cloth on the surface side of the supporter is cut. Protruding operation is performed according to the movement, but it is suppressed by the cloth on the surface side of the movement supporter, that is, the movement is gentle, and the cloth on the surface side of the supporter assists the returning movement for the returning movement. And quickly return to the original state. In addition, the shock absorbing pad is provided with multi-stage cuts, so that it can be used for knee and elbow movements. It becomes possible to make it.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

(First embodiment)
(Composition of shock absorbing pad)
The shock absorbing pad 1 of the present embodiment is used for an elbow, and the overall shape is formed in a substantially square shape, and a notch 2 is formed in an arc shape 2a at substantially the center thereof. The notch 2a is provided with a non-notch portion 2c in which one end 2b and the other end 2b of the notch 2a are provided without being cut at a predetermined interval, and the inside of the notch 2 is configured as a movable portion 4. Moreover, the slit 6 is formed in the substantially rectangular outer periphery. As the impact absorbing pad 1, a flexible low resilience urethane foam, rubber, sponge, synthetic resin, or the like can be used. The size of the shock absorbing pad 1 here is about 15 to 20 cm in length, about 10 to 15 cm in width, and about 10 mm in thickness.

  The notch 2 is a notch penetrating in the thickness direction, and is formed in the substantially center of the substantially square shock absorbing pad 1 without being connected to the outer periphery of the pad. The cut portion 2 of the present embodiment has an arc shape. The notch 2 is formed so as to surround the kneecap Et and the elbow head Kt, and the inside of the notch 2 is the movable part 4. The one end portion 2b and the other end portion 2b of the cut portion 2 are arranged so as to face each other, and the position thereof is on the same circumference as the circular cut portion 2a, and the non-cut portion 2c serving as a connecting portion is also provided. Located on concentric circles. Further, the cross-sectional wall 2k1 of the cut portion 2 is configured as a cut that is in contact with the opposing wall 2k2 in the thickness direction. When the movable portion 4 inside the cut portion 2 moves, the cross-sectional wall 2k1 contacts the opposing wall 2k2. While moving.

The non-cut portion 2c is a connecting portion provided at a predetermined interval between the one end portion 2b and the other end portion 2b of the cut portion 2, and serves as a fulcrum when the movable portion 4 moves. The one end 2 b and the other end 2 b of the cut portion 2 are through holes having a predetermined size, that is, a hole larger than the cut portion 2. Therefore, the movable part 4 is configured to be easily movable. Further, it also has a role of preventing cracks from progressing from the end 2b of the cut portion 2 when a force is applied to the shock absorbing pad 1. In the present embodiment, the non-cut portions 2 c are both positioned so as to be substantially parallel to the outer peripheral portion 1 a of the shock absorbing pad 1.
A second notch 3 is formed outside the notch 2. Thus, in the present embodiment, the two cut portions 2 and 3 are formed, but the number of the cut portions 2 and 3 is not limited to the number, and two or more cut portions may be formed. The one end 3b and the other end 3b of the second notch 3 are arranged so as to face each other, and the position thereof is at the same circumferential position as the circular notch 3a, but the notch that becomes the connecting part The non-notched part 3c without a mark is also located on a concentric circle. Therefore, the second cut portion 3 is movable so that the inside of the second cut portion 3 is linked as the second movable portion 5.
In addition, the position from the one end 3b to the other end 3b of the second notch 3 is the same as the position of the one end 2b and the other end 2b of the first notch 2. It is in a different position. That is, as shown in FIG. 2, the position from the position of the center O of the circular cut 2 to the one end 3b of the second cut 3 to the other end 3b is also the one end of the first cut 2 The positions of the part 2b and the other end 2b are also arranged at the same angle θ so that they do not become the same position. If this is the same position, the first and second movable parts 4 and 5 can move about the same point as a fulcrum, and the part is easily bent, but by shifting the position as in the present embodiment It is difficult to bend. In addition, the angle θ between the positions of the one end portions 2b and 3b and the other end portions 2b and 3b of the cut portions 2 and 3 from the position of the center O of the circular cuts 2 and 3 of the present embodiment is 180 degrees or more. Is provided.

  The slit 6 is a cut formed on the outer periphery of the shock absorbing pad 1. In addition to the role of making the shock absorbing pad 1 bend easily, the slit 6 is used here to narrow the gap of the slit 6 (to eliminate the slit width) so that the movable parts 4 and 5 slightly protrude and move easily. It is formed toward the notches 2 and 3. In the present embodiment, a total of four slits 6 are formed at approximately equal intervals on each of the two opposite sides 1b of the shock absorbing pad 1, and two slits 6 are provided on each of the other two opposite sides 1a. Is formed. The size of the upper and lower slits is different, the size of the bend can be changed back and forth, and the front and back positions of the shock absorbing pad 1 can be confirmed.

Accordingly, in the shock absorbing pad 1, the movable portions 4 and 5 are movable as shown in FIG. 3B in response to the movement of bending the elbow K and projecting the elbow head Kt. At this time, the movable parts 4 and 5 project and move with the non-cut parts 2c and 3c as fulcrums (following movement). From this, when the elbow K is bent and the elbow head Kt only slightly protrudes, only the first movable part 4 protrudes, and when the elbow K is largely bent and the elbow head KT largely protrudes , Not only the first movable part 4 but also the second movable part 5 protrudes. Here, symbol E in FIG. 3 (b) indicates a knee, and the knee head Et of the knee E is larger than the first movable portion 4, and when the knee E is bent, it comes into contact with the knee head Et. The second movable part 5 is brought into contact with the size of Et. From such a configuration, in this embodiment, the elbow supporter and the knee supporter can be combined.
On the other hand, corresponding to the movement of the elbow head Kt to return to the original position, the movable parts 4 and 5 return to the original position with the non-cut portions 2c and 3c as fulcrums, respectively. That is, the shock absorbing pad 1 has a flat plate shape (FIG. 3A).

  Here, the cut portion 2 is formed in an arc shape, but the cut portion 2 can be formed in various shapes. For example, a trapezoidal shape as shown in FIG. 4 or a rectangular shape as shown in FIG. 5 can be used. Further, as shown in FIG. 6, a square or trapezoidal first cut portion 2 is formed inside the arcuate cut portion 3, or the circle is formed outside the square or trapezoid cut portion 2. It is also possible to form an arcuate second cutout 3. The notches 2 and 3 may be triangular.

(Knee / Elbow Supporter)
The knee / elbow supporter of the present embodiment is a supporter that is used with the above-described shock absorbing pad 1 inserted (FIG. 7). Although described as an elbow supporter, it may be a knee supporter or a supporter for both elbows and knees. The knee / elbow supporter 10 includes a cylindrical supporter body 10b and a front pocket 10a. The supporter body 10b is attached to the knee K through the foot and is made of a stretchable cloth. The front pocket 10a is provided on the front side (elbow head Kt side) of the supporter main body 10b, and is configured integrally with a stretchable cloth.
The front pocket 10a of the present embodiment has the same substantially rectangular shape as the shock absorbing pad 1, but the length in the vertical direction and the width direction is slightly larger than the length in the vertical direction and the width direction of the shock absorbing pad 1, respectively. It is structured short. After the shock absorbing pad 1 is placed in the front pocket 10a, the opening of the front pocket 10a is stitched. During the suturing, the slit 6 is sewn in a state where the gap is eliminated (shrinked). It is also possible to reduce the interval between the slits 6 by attaching an adhesive to the gaps between the slits 6. Therefore, when the shock absorbing pad 1 is housed in the front pocket 10a, the gap of the slit 6 formed on the outer periphery of the shock absorbing pad 1 disappears, and the shock absorbing pad 1 is, as shown in FIG. It becomes a bowl shape and fits to the kneecap Et, and the movable parts 4 and 5 slightly protrude (FIG. 8B), making it easy to move in the protruding direction. The shock absorbing pad 1 and the front side pocket 10a do not have a joint and are merely stored (the shock absorbing pad 1 is disposed without being fixed in the front side pocket 10a of the supporter 10). ). And it inserts in the front side pocket 10a of the supporter 10 so that the notch | notch parts 2c and 3c may be located above the elbow head Kt.
Here, when the shock absorbing pad 1 is stored in the front pocket 10 smaller than this, the gaps between the slits 6 are eliminated. At this time, the shock-absorbing pad 1 has a bowl-like shape with its center portion protruding. That is, the cuts 2 and 3 at the center are curved. Therefore, by adjusting the gap between the slits 6, the shock absorbing pad 1 is easily bent, and the operation of projecting the cut portions 2 and 3 is easily performed.

The operation of the knee / elbow supporter 10 of the present embodiment will be described. As shown in FIG. 8B, when the knee E is bent and the kneecap Et protrudes, The two movable parts 5 also move continuously. On the other hand, when the knee E is returned to the original state (the unbent state), the supporter 10 follows the movement of the knee E and returns to the original state. Return to state. As shown in FIG. 8B, when the supporter 10 is worn and the knee E is bent to project the kneecap Et, the shock absorbing pad 1 is bent, but the first movable portion 4 and the second movable portion are bent. The part 5 jumps out according to the protruding state. Here, as shown in FIG. 3B, in the state in which the first movable part 4 and the second movable part 5 protrude from the shock absorbing pad 1 (jump out to the outside), the entry and exit of air can be ensured.
Here, when the elbow K is returned to the original state (the unbent state), the supporter 10 follows the movement of the elbow K and returns to the original state. Is restored to its original state, but the cloth 10c on the front side of the front pocket 10a assists this returning operation. In the present embodiment, the front pocket of the supporter 10 (corresponding to the kneecap portion and the elbowcap portion) 10a so that the non-cut portions 2c, 3c of the shock absorbing pad 1 are positioned above the kneecap Et and the elbowcap Kt. Although it was put in, it may be located under the kneecap Et or the elbowcap Kt.

(Second Embodiment)
The outer periphery of the shock absorbing pad 11 of the present embodiment is formed in a substantially circular shape. Moreover, although the 1st notch part 2 and the 2nd notch part 3 are provided, the 1st notch part 2 and the 2nd notch part 3 are provided via the space | gap 2d and 3d. Accordingly, the air inlet / outlet is provided through the gaps 2d and 3d, and the perspiration of the shock absorbing pad 11 is improved.
