Therefore, in the present embodiment, the shape of the band-like knitted fabric is formed in a substantially elliptical closed ring shape.

Further, in the present embodiment, as shown in FIGS. 1 and 2, when the joint supporter 1 is worn and viewed from the side of the knee joint H, the band-shaped knitted fabric body is crossed in a substantially X shape. A pair of Specifically, as the first band-shaped knitted fabric body 10a, as shown in FIG. ), and further straight through the side surface of the knee joint H in an oblique direction as shown in FIG. A continuous band-shaped knitted fabric body is provided so as to surround the knee joint H in a substantially U shape from above (so as to enclose the knee joint H). Moreover, as the second band-shaped knitted fabric body 10b, as shown in FIG. ), further straight through the side surface of the knee joint H in an oblique direction as shown in FIG. 1(b), and as shown in FIGS. A continuous band-shaped knitted fabric body is provided so as to surround the knee joint H from below in a substantially U-shape (so as to enclose the knee joint H). Furthermore, when the joint supporter 1 is viewed from the side of the knee joint H when worn, the first strip-shaped knitted fabric body 10a and the second strip-shaped knitted fabric body 10b are crossed in an X shape. It is provided.
Here, "the outer side of the body surface and the inner side of the body surface" means "the front side of the knee is the outer side and the back side of the knee is the inner side".

In addition, the first strip-shaped knitted fabric body 10a and the second strip-shaped knitted fabric body 10b are integrated by knitting them with the same knitting structure at the intersection position, thereby forming a pair of strip-shaped fabrics. The knitted fabric body is configured to form a pair of loop shapes, like portions of a so-called coiled spring, connected at intersections.

More specifically, as shown in FIGS. 1 and 2, the first band-shaped knitted fabric body 10a arranged on the surface side of the knee joint H when worn is substantially U-shaped (substantially U-shaped on the lower side). and the substantially U-shape of the second band-shaped knitted fabric body 10b (substantially U-shape on the upper side) form one annular loop shape. Further, the substantially U-shaped first belt-shaped knitted fabric body 10a (substantially U-shaped upper side) disposed on the back side of the knee joint H when worn, and the substantially U-shaped second belt-shaped knitted fabric body 10b.

The second course is knitted with 20 denier polyurethane and 70 denier nylon single covered yarn, and the third course is 360 denier polyurethane with 70 denier nylon double covered yarn inserted by inlay knitting. .
Of course, the knitting structure of the weak tightening force knitted fabric portion 20 and the wearing position indication mark 21 is not limited to such a configuration, and can be changed as appropriate.

The slip-preventing strip 30 is a slip-preventing strip that prevents the joint supporter 1 from moving when the joint supporter 1 is worn. Further, it constitutes a so-called taping anchor portion that tightens the leg with a certain strength when the joint supporter 1 is worn.
In this embodiment, as shown in FIGS. 1 to 3, a pair of slip-preventing strips 30 having a slip-preventing function are provided at the upper end and the lower end of the joint supporter 1. FIG.
Specifically, it is configured to include an upper slip-preventing strip 31 arranged at the upper end of the joint supporter 1 and a lower slip-preventing strip 32 arranged at the lower end of the joint supporter 1 . . The vertical length (width) of the upper slip-preventing strip 31 is longer than the vertical length (width) of the lower slip-preventing strip 32 .
The slip-off prevention strip 30 is composed of a knitted fabric portion having a weaker tightening force than the strong tightening force knitted fabric portion 10 .

In the present embodiment, the strip 30 for preventing slipping down is composed of two layers of knitted structures, the inner knitted structure arranged on the inner side and in contact with the leg, and the outer knitted structure covering the outer side of the inner knitted structure. There is a configuration using

As described above, in this embodiment, the non-slip yarn is used for the inner knitting structure, so that the slip-preventing strip 30 can exhibit the anti-slip function.
Of course, the configuration (the number, the configuration of the anti-slip function, etc.) of the anti-slip strips 30 is not limited to the above configuration, and can be changed as appropriate.
In addition, the configuration of the knitting structure of the slip-off prevention strip 30 is not limited to the above configuration, and it is possible to make the knitted fabric portion with a weaker tightening force than the strong tightening force knitted fabric portion 10 and prevent slipping. Any configuration may be used as long as it can have the function.
Furthermore, in the present embodiment, the two slip-preventing strips, that is, the upper slip-preventing strip 31 and the lower slip-preventing strip 32 are provided. Instead, one of the upper and lower ends may be provided with a strip for preventing slipping down. However, when it is provided at one of the ends, it is desirable to provide it at the upper end.

The joint supporter 1 having such a configuration can be manufactured by creating a program for knitting the knitted fabric of each part and transferring the program to a circular knitting machine.

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

First, as shown in FIG. 3, the wearer puts the joint supporter 1 on the leg K at the correct wearing position, using the wearing position indication mark 21 as a mark. In this state, the joint supporter 1 of the present embodiment is formed by forming the elastic material into a tubular shape, and the tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) is formed in the area of the low tightening force knitted fabric portion 20. Since the arrangement is such that the band-shaped knitted fabric body is arranged at a desired position, simply by wearing the joint supporter 1 at a proper position.
4(a) and 5(a), when the wearer of the joint supporter 1 starts walking, the upper side of the back of the knee via the knee flexor (not shown) is indicated by a white arrow. A force F1 is generated from right to left on the drawing. At this time, as shown in FIG. 5(a), the knee joint H to be arranged substantially at the center of the first belt-shaped knitted fabric body 10a is the fulcrum C, and the first belt-shaped knitted fabric body 10a is substantially U-shaped. Of the belt-shaped knitted fabric body, the curved portion on the inner side (back side of the knee) is the point of effort R, and of the substantially U-shaped belt-shaped knitted fabric body of the first belt-shaped knitted fabric body 10a, the outer 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. 5(a), the knee joint H to be arranged substantially at the center of the second belt-shaped knitted fabric body 10b is the fulcrum C, and the second belt-shaped knitted fabric body 10b is substantially U. The bending portion on the outer surface side (knee front side) of the letter-shaped knitted fabric strip is the point of effort R, and the inner surface side (knee back side) of the substantially U-shaped strip-shaped knitted fabric body of the first strip-shaped knitted fabric body 10a. 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.
As a result, as shown in FIGS. 4(b) and 5(b), force F1 and force F2 acting in opposite directions across the knee joint H (force directed from left to right indicated by white arrows) are generated. A load is applied to 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 bent state. At this time, as shown in FIG. 5(c), the knee joint H is the fulcrum C, and the curved portion on the outer surface side (knee front side) of the substantially U-shaped belt-shaped knitted fabric body of the first belt-shaped knitted fabric body 10a is The point of effort R and the curved portion on the inner surface side (the back side of the knee) of the substantially U-shaped knitted fabric belt of the first knitted fabric belt 10a serve as points of action S, and the principle of leverage works.
At the same time, as shown in FIG. 5(c), the knee joint H is the fulcrum C, and the curved portion on the inner surface side (the back side of the knee) of the substantially U-shaped knitted fabric belt of the second knitted fabric belt 10b. is the point of effort R, and the curved portion on the outer surface side (knee front side) of the substantially U-shaped knitted fabric strip of the second knitted strip fabric 10b becomes the point of action S, and the principle of leverage works.
As a result, as shown in FIGS. 4(c) and 5(c), force F1 and force F2 acting in opposite directions across the knee joint H are applied to the leg K, and the knee can be easily extended. can.

In addition, by bending the knee, a pair of annular loop shapes formed by the first strip-shaped knitted fabric body 10a and the second strip-shaped knitted fabric body 10b and a pair of substantially wave-shaped loop shapes are formed. An elastic force like a so-called spring effectively acts on each of them. Therefore, a so-called spring-like elastic force acts in the horizontal direction and the vertical direction of the knee joint H, and this elastic force acts as an auxiliary force when bending and stretching the knee and raising and lowering the leg, making it easier to bend the knee. can be bent and the legs can be easily raised and lowered.

The joint supporter 1 configured as described above has the following effects.

A strong tightening force knitted fabric portion 10 and a weak tightening force knitted fabric portion 20 formed by forming a stretchable material in a tubular shape and having different stretchability (strong and weak stretchability), and the strong tightening force knitted fabric portion 10 When the joint supporter 1 is worn, the outer side of the body surface surrounds the knee joint H, and the side surface of the knee joint H is diagonally passed through to form the back side of the one side. By forming a continuous band-shaped knitted fabric body that closes so as to surround the knee joint H on the inner surface side of the, when bending and stretching the knee joint H around the knee joint H, the strong tightening force knitted fabric A so-called lever principle can be applied via the portion 10 (strip-like knitted fabric). Therefore, the force acting on the leg K of the wearer when the knee joint H is bent and stretched can be effectively utilized. Therefore, the joint supporter can realize smooth and easy bending and stretching of the knee joint H 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 that allows the leg to be easily extended forward and lifted upward. Such an effect is particularly effective for the elderly and those with knee diseases who find it difficult to bend, stretch, and raise and lower their knees when walking or climbing stairs.

In addition, as a configuration of the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) having a stronger tightening force (weak stretching force) than the weak tightening force knitted fabric portion 20, the knee is stretched from the outer surface side to the inner surface side of the body surface. By arranging the strong tightening force knitted fabric part 10 (belt-shaped knitted fabric body) so as to surround the joint H, when the knee joint H is bent and stretched, the strong tightening force knitted fabric part 10 (belt-shaped knitted fabric body) The joint H can be effectively supported. That is, since the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) can be used as a so-called taping, when bending and stretching the knee joint H, the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) can be The joint can be prevented from wobbling, and the knee joint H can be fixed in the correct position. Therefore, damage to the knee joint H can be effectively prevented.
Further, by forming the ends of the strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) into a substantially U-shape, the knee joint H can be surrounded without loss as shown in FIGS. 1 and 2 . Therefore, the high tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) can hold the knee joint H even more firmly.

Furthermore, when the joint supporter 1 is viewed from the side of the knee joint H when worn, a pair of band-shaped knitted fabric bodies are provided so as to cross each other in a substantially X shape, specifically, the first band-shaped knitted fabric. By forming the base body 10a and the second band-like knitted fabric body 10b so as to cross each other in a substantially X shape, the so-called principle of leverage can be made to work even more strongly. Therefore, 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 pair of band-like knitted fabric bodies.

Further, the first belt-shaped knitted fabric body 10a and the second belt-shaped knitted fabric body 10b are integrated at their intersection positions to form a pair of loop shapes in which the pair of belt-shaped knitted fabric bodies are connected at their intersection positions. By adopting such a configuration, the pair of strip-like knitted fabric bodies can be efficiently cooperated to move, and the so-called principle of leverage can be made to work even more efficiently. Therefore, 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 body 10a and the second strip-shaped knitted fabric body 10b.

Further, the pair of annular loop shapes integrated at the intersection position are arranged in parallel in a laterally symmetrical direction in the lateral direction of the joint supporter 1, and the pair of wavy shapes integrated at the intersection position. By arranging the loop shapes in parallel in a vertically symmetrical direction in the longitudinal direction of the joint supporter 1, each loop shape can generate a so-called spring-like elastic force when the knee is bent. . Therefore, when the knee is bent, a so-called spring-like elastic force acts in the horizontal direction and the vertical direction of the knee joint H, and this elastic force assists when the knee is bent and stretched or when the leg is raised and lowered. The joint supporter 1 can work as a joint supporter 1, which can bend the knee more easily and raise and lower the leg easily.

Further, by knitting the first strip-shaped knitted fabric body 10a and the second strip-shaped knitted fabric body 10b at the crossing positions with the same knitting structure and integrating them, it is possible to prevent the thickness of the joint supporter 1 from increasing. , a complicated stitch structure can be prevented. Therefore, the joint supporter 1 can be produced with high manufacturing efficiency and at low cost.

In addition, in the first band-shaped knitted fabric body 10a, the knee joint H is surrounded in a substantially U-shape from below on the outer surface side of the body surface, and a substantially U-shaped end (a band-shaped The top part of the upper side of the knitted fabric body) is connected to a slip-off prevention strip 30 (upper slip-off prevention strip 31) having a wide length in the vertical direction, and in the second strip-shaped knitted fabric body 10b , the substantially U-shaped end (top of the upper side of the belt-shaped knitted fabric) located on the surface side of the body surface is attached to the slip-off prevention belt-shaped piece 30 (upper slip prevention belt-shaped piece 30) having a wide length in the vertical direction. By connecting it to the falling prevention band piece 31) and surrounding the knee joint H in a substantially U shape from below on the inner surface side of the body surface, the strong tightening force knitted fabric portion 10 (band-shaped knitted fabric body) The effect of lifting the knee joint H while firmly holding the knee joint H can be obtained. Therefore, the joint supporter 1 can raise the knee more easily.

In addition, by providing both the strong tightening force knitted fabric portion 10 having poor stretchability and the weak tightening force knitted fabric portion 20 having good stretchability, when bending and stretching the knee joint H, the strong tightening force knitted fabric portion In addition to the effects provided by the base portion 10, the joint supporter 1 can be provided that does not impede mobility when the joint is moved or exercised.

In addition, the supporter can be effectively prevented from slipping down during use by providing the slip-preventing strips 30 at the upper end and the lower end.
In addition, the vertical length (width) of the upper slip-preventing strip 31 is longer than the vertical length (width) of the lower slip-preventing strip 32, thereby making it easier to use. It is possible to more effectively prevent the supporter from slipping down.

Further, by providing the wearing position indication mark 21 indicating the wearing position of the joint supporter 1, it is possible to make the joint supporter 1 easy for the user to easily grasp the normal wearing position.

The shape, orientation, width, etc. of the high tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) are not limited to those of the present embodiment, and can be changed as appropriate. For example, the end portion of the high tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) may be configured to have an approximately V shape instead of an approximately U shape. That is, when the supporter is worn, the strong tightening force knitted fabric portion passes so as to surround the joint on one side (outer surface side) of the body surface, passes through the side surface of the joint in an oblique direction, and extends to the back side of the one surface side. As long as it is formed of a continuous band-shaped knitted fabric body that closes so as to surround the knee joint H on the other side (inner side) of the body surface, the shape and direction can be changed as appropriate.
Further, in addition to the configuration of the embodiment of the present invention described above, a configuration may be adopted in which a new strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) is provided. For example, a configuration may be adopted in which a strong tightening force knitted fabric portion 10 (belt-shaped knitted fabric body) extending in the lateral direction of the joint supporter 1 is provided at a position where the knee joint H can be supported from below. With such a configuration, the joint supporter can hold the knee joint H more firmly.

Further, the intersection position of the first strip-shaped knitted fabric body 10a and the second strip-shaped knitted fabric body 10b is not limited to that of the present embodiment, and can be changed as appropriate.
