DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a knee, an elbow, an ankle,
The present invention relates to a supporter applied to a joint of a human body such as a wrist, a shoulder, and a waist, and an elastic body added to this type of supporter to hold the joint with its own elasticity.

[0002]

2. Description of the Related Art As a supporter of this type, a cylindrical supporter (Japanese Utility Model Application Laid-Open No. 1-178525, Japanese Patent Publication No. 62-401) is known.
No. 3) and a winding type supporter (Japanese Patent Laid-Open No. 10-1).
No. 27677). In any of the supporters, an elastic body for holding the joint may be used in some cases. As the elastic body, a band formed by crushing a closely wound coil spring is often used. In addition, several monofilaments arranged in parallel are used as core materials, and the periphery thereof is covered with a braided outer material to form a linear band, which is commercially available.

[0003]

As described above, the elastic body formed in the shape of a straight band can be easily elastically deformed in the thickness direction, but hardly elastically deformed in the width direction. For this reason, in a supporter using this kind of elastic body, the movement of the joint may be suppressed by the elastic body, and it is unavoidable that the supporter may fall down in an emergency. In a state in which the joint is bent, the elastic body is lifted and deformed, so that it is difficult to fit the human body, and the elastic body that is forcibly bent generates a tension force, which easily gives the user a sense of discomfort. The supporter may move to the side receiving the tension force.

Since the elastic body is formed in a linear band shape, the range that can be held or captured by the elastic body is limited to the width range of the elastic body, and there is a disadvantage that the holding range of the joint is only linear. . Although it is easy to maintain a wider range by using a plurality of elastic bodies, the overall cost of the supporter is high and the practicality is lacking in that it promotes the above-mentioned adverse effects.

SUMMARY OF THE INVENTION It is an object of the present invention to ensure that the supporter can be fitted to the human body without causing any discomfort such as a feeling of pressure or cramp when worn, and to prevent the supporter body from shifting when the joint is bent or stretched. An object of the present invention is to provide a joint supporter that can surely prevent the joint. Another object of the present invention is to provide a reinforcing member suitable for a supporter for a joint, which can follow and deform in all directions in accordance with the movement of the joint without resistance, and can securely hold the joint over a wide range. It is in.

[0006]

A supporter according to the present invention comprises:
The vehicle includes a supporter main body 1 and an elastic body 2 attached to the supporter main body 1 and holding a joint part with its own elasticity. The elastic body 2 is formed by fixing an elastically deformable linear body 20 to the supporter body 1 in an annular shape. Thus, the elastic body 2 is characterized in that it can elastically deform in all directions following the bending and stretching operation of the joint.

The supporter body 1 is provided with a holding portion 21 for defining a mounting pattern of the elastic body 2. The linear body 20 is attached to the holding portion 21 such that the ends 23, 23 are adjacent to each other and overlap with each other, so that the ends 23, 23 are opposite to each other following the bending and stretching operation of the joint. Allow them to move.

The elastic body 2 is formed by fixing an endless annular ring body 2a formed by connecting the ends of the linear body 20 to the supporter body 1.

The linear body 20 is formed of an elastically deformable plastic monofilament. The elastic body 2 is formed in a track pattern from one end to the other end of the supporter body 1 with the bending center portion of the supporter body 1 interposed therebetween. The bending patterns of the first holding part 6 and the second holding part 7 divided at the bending center are set to different shapes. The supporter body 1 is formed in a tubular shape from a knitted fabric. Linear body 20
Each of the ends 23, 23 is rounded into a sphere.

The elastic body for a supporter of the present invention is mounted on a supporter body 1 mainly made of fabric, and holds the joint with its own elasticity. The elastic body 2 is formed of a linear body 20 that can be elastically deformed in all directions, and can be fixed to the supporter body 1 in a predetermined mounting pattern.

The above-mentioned elastic body has an end portion 23 of the linear body 20,
23 are superimposed on each other, and are fixedly formed in an annular mounting pattern so that both ends 23, 23 can move in opposite directions.

An endless annular ring body 2a is formed by connecting the ends of the linear bodies 20, and the ring body 2a is fastened to the supporter body 1 to form the elastic body 2. Linear body 20
Is formed of an elastically deformable plastic monofilament.

[0013]

Function and Effect of the Invention Elastically deformable linear body 20
Is elastically fixed to the supporter 1 to form an elastic body 2, so that the joint can be held by the elastic body 2 and the elastic body 2 can be elastically deformed in all directions without resistance following the bending and stretching operation of the joint. Can be done. As described above, according to the elastic body 2 having no restriction on the direction in which the support body 1 can be deformed, the supporter main body 1 can be fitted to a human body regardless of the bending state of the joint, and a constant holding force can be always obtained. Demonstrate,
It is possible to eliminate a feeling of discomfort such as a feeling of oppression or crampedness when worn.

According to the elastic body 2 in which the end portions 23 and 23 are overlapped in the holding portion 21 so as to be able to freely move in opposite directions, when the supporter main body 1 expands and contracts in accordance with the bending and stretching operation of the joint portion. Since the end portions 23 and 23 can move freely in accordance with this movement, the elastic body 2 can be more naturally fitted to the human body, and can be deformed when the elastic body 2 is largely bent and deformed. Resistance increases,
It can also eliminate the feeling of tension. Even when the fastening pattern of the elastic body 2 and the size of the supporter are different, it can be dealt with without any trouble only by changing the cutting length of the linear body 20.

An endless annular ring 2a is formed by connecting the ends of the linear members 20, and the ring 2a is fixed to the supporter body 1 in an annular shape to form the elastic member 2. The deformation stress can be made uniform in the circumferential direction of the ring body 2a.

The elastic body 2 is mounted, for example, in a track pattern, so that both sides of the joint can be held over a wide range, and at the same time, the displacement of the supporter body 1 can be restricted. Therefore, as compared with the conventional elastic body 2, a supporter having an improved joint holding force can be manufactured at lower cost, and despite the increased number of holding points, the movement of the joint by the elastic body 2 can be improved. And the supporter body 1 receives the tension force by the elastic body 2, thereby eliminating the adverse effects such as improving the support function for the joint part and improving the usability at the same time.

The ring body 2a can be formed of an elastically deformable plastic molded product.
0, for example, if a stranded wire or a plastic monofilament is used as a material and the ends thereof are connected to each other to form, the ring body 2a can be formed at a lower cost than in other cases. Supporters can be provided at low cost.

For example, in the knee supporter shown in the embodiment, the mounting pattern of the elastic body 2 is set to be different between the first holding portion 6 on the upper leg and the second holding portion 7 on the lower leg. . As described above, by changing the mounting pattern of the holding portions 6 and 7, the holding force and the holding range of the holding portions 6 and 7 are changed to be large and small, and the holding force and the like are changed according to the mounting portion of the supporter. A suitable elastic body 2 with no excess or shortage can be configured.

[0019]

(Embodiment 1) FIGS. 1 to 4 show an embodiment of the present invention suitable for a knee supporter. In FIG. 1, the supporter includes a supporter body 1 formed by knitting a stretchable yarn into a tubular shape, and a pair of elastic bodies 2 and 2 disposed on both left and right sides of the supporter body 1. The supporter main body 1 has an opening diameter on the upper leg side larger than an opening diameter on the lower leg side corresponding to upper and lower thighs having different thicknesses. It is formed in an oval shape. The patella protection part 3 is formed by using a different knitting structure using a different stretch yarn from the other part, and completely covering the patella, thereby relieving the knee joint pain by body heat. Can be. The upper and lower ends of the supporter body 1 are folded back toward the inner surface of the cylinder, and then sewn to form a band portion 4. Since the band portion 4 has a stronger binding force than the other portions, it is useful to prevent the supporter main body 1 from shifting and moving.

The elastic body 2 is constituted by fixing an elastically deformable endless annular ring body 2a to the supporter main body 1 in a mounting pattern shown in FIG. The ring body 2a is formed of a monofilament having a circular cross section made of an elastically deformable plastic material. After cutting a long monofilament to a predetermined length, both ends of the cut piece are connected to each other via a tube-shaped connecting piece 5 to form an endless ring (see FIG. 3). The monofilament is formed of a polyamide resin, polycarbonate, polyacetal, or the like, which is excellent in toughness, hard to bend, and hard to bend.

The ring body 2a in the free state is substantially circular.
The supporter body 1 as shown in FIG.
The patch cloth 12 is sewn on the inner surface of the. In other words, patch cloth 1
The ring body 2a is held in a predetermined pattern by the bag-shaped groove formed in Step 2.

As shown in FIG. 2, the elastic body 2 is provided with a first holding portion above the bending center portion of the supporter body 1, that is, a cross-sectional position passing through the vicinity of the vertical center of the patella protection portion 3 therebetween. The part 6 and the second holding part 7 below the part 6 form a track pattern of a race track. Specifically, both holding portions 6 and 7 are provided with a gentle front bending portion 8 adjacent to the patella protection portion 3.
And a rear bending portion 9 having a smaller radius of curvature located on the back side of the knee than this, and vertically reversing, and reversing bending portions 10, 11 continuing to the upper and lower ends of the front and rear bending portions 8, 9 respectively.
It has. The radius of curvature of the inverted bending portion 10 in the first holding portion 6 on the upper leg is set larger than the bending radius of the inverted bending portion 11 in the second holding portion 7 on the lower leg. This is because the holding force and the protection range by the elastic body 2 are increased on the first holding portion 6 side and are reduced on the second holding portion 7 side.
Each of the inverted bending portions 10 and 11 is provided so as to protrude upward and downward from the upper and lower ends of the patella protection portion 3, and the respective bending lines are close to the upper and lower band portions 4 and 4. When the entire elastic body 2 is curved toward the back of the knee in this way, the resilience of the elastic body 2 when bending and stretching the knee can be weakened, and the elastic body 2 is brought into close contact with the legs to sufficiently adjust the knee. It can be fitted in the condition.

FIG. 1 shows a use state of the supporter.
In use, the outer surface of the patella is completely covered with the patella protection part 3, so that the knee joint pain can be relieved by body heat. The elastic body 2 supports the knee joint from the left and right side surfaces, and suppresses the torsion and lateral swing of the knee joint during walking or flexion and extension, and at the same time, prevents the supporter main body 1 from slipping and slipping up. When bending and stretching the knee joint, the front and rear bending portions 8 and 9
Elastically deform and follow the movement of the joint without resistance. Therefore, the supporter main body 1 can be fitted to the mounting portion while maintaining the state where the knee joint is securely held, and even when the knee joint is bent, the resilience of the elastic body 2 causes a feeling of oppression or cramping. Will not occur. Since the knee joint is held by the elastic body 2 arranged in a track pattern,
Compared with the conventional elastic body formed in a belt shape, the knee joint is elastically movable, despite the fact that the elastic body 2 can effectively exert the reinforcing effect by elastically retaining a wider range of the knee joint. You are not restricted by body 2.

(Embodiment 2) FIGS. 5, 6 and 7 show an embodiment in which the present invention is applied to a supporter for an ankle. In this case, the upper part 15, the shin part 16 and the heel part 17 were integrally knitted using a stretchable yarn as a material to form the supporter main body 1, and the elastic body 2 was disposed at a position facing the front part of the ankle. The elastic body 2 includes a first holding part 6 provided on the shin part 16 side and an upper part 1.
The second holding part 7 provided on the side of the track 5 is formed in a track pattern of a race track, and each holding part 6, 7 is formed in a tunnel cross section (FIG. 5b), which is different from the previous embodiment. . The elastic body 2 in this case is also formed by fixing the circular ring body 2a to the supporter main body 1 in a predetermined pattern. Other components are the same as those of the embodiment, and the same members are denoted by the same reference numerals and description thereof will be omitted.

(Embodiment 3) FIGS. 8 to 10 show an embodiment in which the structure of the elastic body 2 is changed. There, the supporter main body 1 was formed in the same manner as in the first embodiment. However, the patella protection part 3 was omitted, and that part was also formed with the same knitting structure as the other parts. Similarly to the elastic body described in the first embodiment, the elastic body 2 is formed in a track pattern by the first holding part 6 and the second holding part 7, but the way of fixing the linear body 20 to the supporter body is different. .

More specifically, a holding portion 21 for defining a mounting pattern of the elastic body 2 with respect to the supporter body 1 is provided in advance. The holding portion 21 is formed by sewing the patch cloth 12 on the outer surface of the supporter main body 1 in a track pattern. However, the end including the start and end 22 of the holding portion 21 is left unsewn. An elastic body 2 is formed by inserting a linear body 20 cut longer than the circumference of the track pattern into the holding portion 21.

As shown in FIG. 8, the linear body 20 is
When the joint is bent and stretched, the ends 23 of the linear body 20 move in the opposite direction following the operation when the joint is bent and stretched. I can do it. The overlapping range of the both ends 23, 23 is indicated by the symbol R in FIG. As shown in FIG. 10, a spherically rounded sliding portion 24 is formed at the tip of each end 23 to prevent the ends 23 from getting caught on the inner surface of the backing cloth 12 when floating. The sliding portion 24 can be formed by heating and half-melting the linear body 20 and then solidifying, and the spherical roundness is formed by a contraction action at the time of solidification. After the linear body 20 is loaded, the start and end 22 of the holding unit 21 are sewn to complete the supporter.

In this embodiment, the side portion 25 surrounded by the holding portion 21 is formed of a stretchable fabric different from the supporter body 1.
More specifically, the side portions 25 are formed of stretchable fabric including a ceramic thread that emits far-infrared rays so that the knee joint can be kept warm from the side. In the supporter of the second embodiment, the elastic body 2 can be configured so that the end can move freely, as in the case of this embodiment.

As can be understood from the above embodiment, the number of elastic bodies 2 to be used can be arbitrarily selected from one or more according to the difference in the application location of the supporter and the difference in the application purpose. The mounting pattern of the elastic body 2 with respect to the supporter body 1 can be freely changed as necessary. For example, a concave portion or a protruding portion may be provided in the middle of the pattern, such as an ellipse, an ellipse, a leaf shape, or a petal shape. . The supporter may be of a wrapping type. The ring body 2a can be formed by an injection molded product. In this case, the holding pieces can be protruded in a branched manner inside and outside the ring body 2a. Instead of a monofilament, a gut for tennis or badminton, a stranded wire, a stainless wire, or the like can be applied to the linear body 20, or the ring body 2a can be formed.
