Next, with reference to FIGS. 4 and 5, the relationship between the movement and the force of each part when walking while wearing the joint supporter 1 according to the embodiment of the present invention will be described. 4 and 5 show a case of walking from the right side to the left side of the drawing.

First, as shown in FIG. 3, the wearer wears the joint supporter 1 at the regular wearing position of the leg K by using the wearing position indicating mark 21 as a mark. In this state, the joint supporter 1 of the present embodiment is formed by forming the elastic material in a tubular shape, and the tightening force knitted fabric portion 10 (belt-shaped knitted fabric) is formed in the region of the weak tightening force knitted fabric portion 20. Since the structure is such that the band-shaped knitted fabric is arranged, the strip-shaped knitted fabric can be arranged at a desired position simply by wearing the joint supporter 1 at a regular position.
With reference to FIGS. 4 (a) and 5 (a), when the wearer of the joint supporter 1 starts walking, it is indicated by a white arrow on the upper side of the back of the knee via the knee flexor muscle (not shown). A force F1 is generated from right to left on the drawing. At this time, as shown in FIG. 5A, the knee joint H to be arranged at the substantially center of the first strip-shaped knitted fabric 10a has a fulcrum C and a substantially U-shape of the first strip-shaped knitted fabric 10a. Of the shaped strip-shaped knitted fabric, the curved portion on the inner surface side (back side of the knee) is the force point R, and the substantially U-shaped strip-shaped knitted fabric of the first strip-shaped knitted fabric 10a is on the outer surface side (front side of the knee). The curved portion becomes the point of action S, the principle of leverage works, and a force F2 acting in a direction opposite to the force F1 is generated.
At the same time, as shown in FIG. 5A, the knee joint H to be arranged at the substantially center of the second strip-shaped knitted fabric 10b is the fulcrum C, and the substantially U of the second strip-shaped knitted fabric 10b. Of the shaped strip-shaped knitted fabric, the curved portion on the outer surface side (front side of the knee) is the force point R, and of the substantially U-shaped strip-shaped knitted fabric of the first strip-shaped knitted fabric 10a, the inner surface side (back side of the knee). The curved portion of the above becomes the point of action S, the principle of the lever works, and the force F2 acting in the direction opposite to the force F1 is generated.
As a result, as shown in FIGS. 4 (b) and 5 (b), the forces F1 and the forces F2 (forces from left to right indicated by the white arrows) acting in opposite directions across the knee joint H are combined. It is loaded on the leg K and the knee can be easily bent.

On the other hand, when the knee is extended, the restoring force of the elastic material is generated in the joint supporter 1 in the flexed state. At this time, as shown in FIG. 5C, the knee joint H is the fulcrum C, and the curved portion on the outer surface side (front side of the knee) of the substantially U-shaped strip-shaped knitted fabric of the first strip-shaped knitted fabric 10a is The point R, the curved portion on the inner surface side (back side of the knee) of the substantially U-shaped strip-shaped knitted fabric of the first strip-shaped knitted fabric 10a becomes the point of action S, and the principle of leverage works.
At the same time, as shown in FIG. 5C, the knee joint H is the fulcrum C, and the curved portion on the inner surface side (back side of the knee) of the substantially U-shaped strip-shaped knitted fabric of the second strip-shaped knitted fabric 10b. Is the point of effort R, and the curved portion on the outer surface side (front side of the knee) of the substantially U-shaped strip-shaped knitted fabric of the second strip-shaped knitted fabric 10b is the point of action S, and the principle of leverage works.
As a result, as shown in FIGS. 4 (c) and 5 (c), the forces F1 and F2 acting in opposite directions across the knee joint H are applied to the leg K, and the knee can be easily extended. it can.

Further, by bending the knee, a pair of annular loop shapes formed by the first strip-shaped knitted fabric 10a and the second strip-shaped knitted fabric 10b, and a pair of substantially corrugated loop shapes are formed. A so-called spring-like elastic force works effectively on each of them. Therefore, a so-called spring-like elastic force acts in the left-right direction and the up-down direction of the knee joint H, and this elastic force acts as an auxiliary force when bending and stretching the knee and when raising and lowering the foot, which makes the knee easier. Can be bent and the legs can be easily raised and lowered.

The joint supporter 1 having the above configuration has the following effects.

The stretchable material is formed into a tubular shape, and is provided with a strong tightening force knitted fabric portion 10 and a weak tightening force knitted fabric portion 20 having different elastic forces (strength and weakness in the elastic force). When the joint supporter 1 is worn, the structure passes so as to surround the knee joint H on the outer surface side of the body surface, further passes diagonally through the side surface of the knee joint H, and becomes the back surface side of the one surface side. By forming a continuous band-shaped knitted fabric that closes so as to surround the knee joint H on the inner surface side of the knee joint H, a strong tightening force knitted fabric is used when bending and stretching the knee joint H around the knee joint H. The so-called lever principle can be applied through the portion 10 (belt-shaped knitted fabric). Therefore, the force acting on the wearer's leg K when the knee joint H is bent and stretched can be effectively used. Therefore, it is possible to provide a joint supporter capable of smoothly and easily bending and stretching the knee joint H even with a small amount of force. In addition, since the knee joint H can be smoothly bent and stretched, it is possible to provide a joint supporter capable of easily pushing the foot forward and raising it upward. Such an effect is particularly effective for elderly people who are reluctant to bend and stretch their knees when walking or ascending and descending stairs, and for those who have a disease in their knees.

Further, as a structure of the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric) having a stronger tightening force (weak elastic force) than the weak tightening force knitted fabric portion 20, the knee extends from the outer surface side to the inner surface side of the body surface. By arranging the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric) so as to surround the joint H, when the knee joint H is bent and stretched, the knee is formed by the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric). The joint H can be effectively supported. That is, since the strong tightening force knitted fabric portion 10 (strip-shaped knitted fabric) can be used as so-called taping, the strong tightening force knitted fabric portion 10 (strip-shaped knitted fabric) is used when bending and stretching the knee joint H. This can prevent the joint from wobbling and fix the knee joint H in the correct position. Therefore, damage to the knee joint H can be effectively prevented.
Further, by forming the end portion of the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) in a substantially U shape, the knee joint H can be surrounded without loss as shown in FIGS. 1 and 2. Therefore, the knee joint H can be held more firmly by the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body).

Further, when the band-shaped knitted fabric is worn, when the joint supporters 1 are viewed from the side of the knee joint H, a pair of band-shaped knitted fabrics are provided so as to intersect in a substantially X shape, specifically, the first band-shaped knitting The so-called lever principle can be made to work even more strongly by forming the base body 10a and the second strip-shaped knitted base body 10b so as to intersect each other in a substantially X shape. Therefore, the bending and stretching of the knee joint H can be performed more smoothly and easily. Further, when the knee joint H is bent and stretched, the knee joint H can be supported more effectively by the pair of band-shaped knitted fabrics.

Further, the first strip-shaped knitted fabric 10a and the second strip-shaped knitted fabric 10b are integrated at the intersection position to form a pair of loop shapes in which the pair of strip-shaped knitted fabrics are connected at the intersection position. With such a configuration, a pair of strip-shaped knitted fabrics can be efficiently coordinated and moved, and the so-called lever principle can be operated more efficiently. Therefore, the bending and stretching of the knee joint H can be performed more smoothly and easily. Further, when the knee joint H is bent and stretched, the knee joint H can be more effectively supported by the first strip-shaped knitted fabric 10a and the second strip-shaped knitted fabric 10b.

Further, the pair of annular loop shapes integrated at the crossing positions are arranged in parallel in the laterally symmetrical direction in the lateral direction of the joint supporter 1, and the pair of corrugated loops integrated at the crossing positions. By arranging the loop shapes in parallel in the longitudinal direction of the joint supporter 1 in a vertically symmetrical direction, it is possible to generate a so-called spring-like elastic force in each loop shape when the knee is bent. .. Therefore, when the knee is bent, a so-called spring-like elastic force acts in the left-right direction and the up-down direction of the knee joint H, and this elastic force acts as an auxiliary force when bending and stretching the knee and when raising and lowering the foot. It can be a joint supporter 1 that can easily bend the knees and raise and lower the legs.

Further, by knitting the first strip-shaped knitted fabric 10a and the second strip-shaped knitted fabric 10b with the same knitting structure at the intersecting positions and integrating them, it is possible to prevent the thickness of the joint supporter 1 from increasing. , It is possible to prevent a complicated stitch structure. Therefore, it is possible to obtain the joint supporter 1 having good manufacturing efficiency and cost saving.

Further, in the first strip-shaped knitted fabric 10a, the knee joint H is surrounded from below in a substantially U-shape on the outer surface side of the body surface, and a substantially U-shaped end (belt shape) arranged on the back surface side of the knee. The upper top of the knitted fabric is connected to the slip-prevention strip 30 (upper slip-preventing strip 31) having a wide length in the vertical direction, and the second strip-shaped knitted fabric 10b is formed. Has a substantially U-shaped end (top of the upper side of the strip-shaped knitted fabric) arranged on the surface side of the body surface, and a slip-prevention strip-shaped piece 30 (upper slip) having a wide length in the vertical direction. By connecting with the fall prevention band-shaped piece 31) and surrounding the knee joint H from below in a substantially U-shape on the inner surface side of the body surface, the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric) can be used. It is possible to exert the effect of lifting the knee joint H while firmly holding the knee joint H. Therefore, the joint supporter 1 can be used to raise the knee more easily.

Further, by providing both the strong tightening force knitted fabric portion 10 having poor elasticity and the weak tightening force knitted fabric portion 20 having good elasticity, the strong tightening force knitting portion is used when bending and stretching the knee joint H. In addition to the effects of the ground portion 10, the joint supporter 1 can be used as a joint supporter 1 that does not impair motility even when the joints are moved or exercised.

Further, by providing the upper end and the lower end with the strip-shaped piece 30 for preventing slipping, it is possible to effectively prevent the supporter from slipping during use.
Further, by making the length (width) of the upper slip-off prevention strip 31 in the vertical direction longer than the vertical length (width) of the lower slip-prevention strip 32, it is possible to use the strip-shaped piece 32 at the time of use. It is possible to prevent the supporter from slipping down more effectively.

Further, by providing the wearing position indicating mark 21 indicating the wearing position of the joint supporter 1, the joint supporter 1 can be easily grasped by the user at the normal wearing position.

For example, the shape of the end portion of the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) may be formed to be substantially V-shaped instead of substantially U-shaped. That is, when the supporter is worn, the strong tightening force knitted fabric passes so as to surround the joint on one surface side (outer surface side) of the body surface, and further passes diagonally through the side surface of the joint to the back surface side of the one surface side. As long as it is formed of a continuous band-shaped knitted fabric that closes so as to surround the knee joint H on the other surface side (inner surface side) of the body surface, the shape and orientation thereof can be appropriately changed.
Further, in addition to the configuration of the embodiment of the present invention described above, a new strong tightening force knitted fabric portion 10 (strip-shaped knitted fabric) may be provided. For example, a strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric) extending in the lateral direction of the joint supporter 1 may be provided at a position where the knee joint H can be supported from below. With such a configuration, it is possible to provide a joint supporter capable of holding the knee joint H more firmly.
