Abstract

PURPOSE: To provide a uniform protection for the whole of the head, the neck and the spine as well as an auxiliary means against a stooping posture, and lessen a load on a muscle around the neck and the backbone by restricting the flexibility of a band body formed out of jointed band component pieces toward the back contact side thereof, and allowing the free flexibility toward the non-back contact side. CONSTITUTION: A backbone reinforcing band A is made of a band body 1 laid in a cover body 2 having a cushion function as well as a size and a shape for covering the whole back of a human body, in such a state as restricted in flexibility toward the back contact side thereof but freely flexible toward the non-back contact side. At a knot as the joint of the band component pieces 3 and 4 of the body 1, engagement teeth 31 and 41 are superposed on top of each other in such a state as stranded on the back contact surfaces 30a and 40a of mating members, and become free in a strand direction. Thus, the whole of the body 1 becomes freely flexible toward the non-back contact side. Regarding a motion toward an opposite direction, mutually coupled plates 30 and 40 receive the teeth 31 and 41 to form an approximately integral structure. The motion of the body 1 is, therefore, restricted and the flexibility thereof toward the back contact side is restricted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a reinforcing band according to the present invention will be described below with reference to the drawings. First, in the first embodiment, the reinforcement band according to the present invention will be described as a spine reinforcement band for protecting the spine.

(First Embodiment) FIG. 1 is a plan view of a spine reinforcement band as a reinforcement band according to the present invention, FIG. 2 is a plan view of a band body of the spine reinforcement band, and FIGS. 3 and 4 are the same band body. It is explanatory drawing of the strip component piece.

As shown in FIG. 1, the spinal reinforcement band A restricts bending toward the back contact surface side in the cover body 2 having a cushion function formed in a size and shape that covers the entire back of the human body. , The belt body 1 which can be freely bent on the back non-contact surface side
Are arranged to configure.

In the central portion of the cover body 2, two strip bodies 1 are arranged side by side along the spine.

Further, the cover body 2 is formed of cloth or the like, and a plurality of sets of fastening belts 21, 22, 23, 24, 25 are provided on the periphery as fastening means for fastening to the body. A hook-and-loop fastener 26, which is a so-called magic tape, is attached to the tip of each of the pair of belts 21, 22, 23, 24, 25.

Although the cover body 2 itself functions as a cushion, the cover body 2 may be filled with another cushion material.

When the spinal reinforcement band A is worn, the fastening belts 21, 22, 23, 24, 25 are fastened with the surface fasteners 26 in a length according to the body. In the case shown, the fastening belt 21 on the one side and the fastening belt 22 on the other side provided on the upper portion of the cover body 2 are attached to each other on the chest like a cross, and the shoulder is positioned between the fastening belts 21 and 22. It is a thing.

The fastening belts 23, 23 are fastened at the abdomen,
Furthermore, the fastening belts 24, 24, 25, 25 provided at the bottom are
The left and right thighs are wound and fastened.

Here, the structure of the band body 1 will be described in detail with reference to FIGS.

As shown in the figure, the band body 1 is constructed by connecting a large number of band components, and the band components are
The first strip component piece 3 (FIG. 3) in which an odd number of engaging claws 31 are provided at both ends of the engaged plate 30 to form an even number of engaging concave portions 32, and an even number of engaging pieces are provided at both ends of the engaged plate 40. Of the second band component piece 4 (FIG. 4) in which the odd number of engaging concave portions 42 are formed by projecting the engaging claws 41 of the above, and each is formed of an elastic body such as hard rubber. .

The first band component piece 3 and the second band component piece 4 are alternately connected to each other to form the band body 1 to a predetermined length.

At the time of connection, the base ends of the engaging claws 31 and 41 of the two band component pieces 3 and 4 are respectively engaged with the mating engaging recesses 42 and 32.
And the engaging claws 31, 41 on the same surface of the mating engaged plates 30, 40, that is, the back contact surface 30.
Polymerization is carried out on the a and 40a.

As shown in FIGS. 3 and 4, the engaging claws 31 and 41 are connected to the engaged plates 30 and 40 with steps of the same height, respectively. When the two band component pieces 3 and 4 are connected in the above-described state, the engaged plates 30 and 40 are formed into a band shape that is substantially flush with each other.

The back contact surfaces 30a, 30a,
On the 40a side, engaging claws 31, 31 provided at both ends of the engaged plates 30, 40
, 41, 41 are formed between the ribs 5, 41, and by means of the rib 5 and the connecting method as described above, the belt main body 1 regulates bending toward the back contact surface side and does not contact the back. The surface is flexible.

That is, in each of the joints 6 serving as a connecting portion of the strip component pieces 3 and 4, the engaging claws 31 and 41 are connected to the back contact surface 3 on the mating side.
Since they are superposed in the state of riding on 0a, 40a, the riding side is free, and the band body 1 as a whole is bendable on the back non-contact surface side.

On the other hand, the movement toward the opposite side is caused by the mutual engagement plates.
The movements are restricted because the holes 30,40 receive the engaging claws 31,41 and are substantially integrated in structure, and the bending toward the back contact surface side is restricted.

Moreover, as described above, the back contact surfaces 30a, 40a
Since ribs 5 and 5 are formed on a, it is possible to sufficiently resist bending toward the back contact surface side.

By the way, the engaged plates 30, 40 of the strip components 3, 4
Is formed in a thin plate shape so that it can be twisted, and as shown in FIGS. 5 and 6, the width D of each engaging recess is larger than the width d of each engaging claw 31, 41. Therefore, each node 6 has a degree of freedom in the width direction. Therefore,
The entire band body 1 has a structure capable of twisting to some extent.

The belt main body 1 has the above-described structure, and the spine reinforcing belt A is constructed by attaching the belt main body 1 to the cover body 2 as described above (FIG. 1).

Since the cover body 2 has a cushioning function, even if the ribs 5, 5 are attached to the back contact surface 30 as described above.
Even if formed on the a, 40a side, the ends of the ribs 5, 5 do not directly contact the human body and do not cause pain or discomfort.

When the band body 1 is attached to the cover body 2, the band body 1 is attached to the portion of the cover body 2 where the rib 5.5 is in contact.
In order to reinforce the elastic force of the rail body, it is desirable to provide a rail body (not shown) having an appropriate elastic force.

When the spine-reinforcing belt A having the above-mentioned structure is attached, the belt body 1 receives the weight of the upper body with respect to the forward bending posture in daily life and when engaging in work, and the weight of the upper body is applied. It can be supported on the waist through the fastening belts 24, 24, 25, 25 provided at the bottom of the cover body 2,
It is possible to protect the spine and the muscles of the upper body by reducing the load on the muscles as much as possible.

Moreover, since there is no hindrance with respect to the movement in the warp direction and the twisting movement of the body, there is no hindrance in daily life or work.

The elasticity of the belt main body 1 can be changed according to the physique and the degree of forward bending of the person who uses the spinal reinforcement belt A, and various sizes and the like can be prepared. .

Therefore, it can be applied to all men and women of all ages and can be used not only at home but also as a treatment instrument in hospitals and the like.

The heights of the ribs 5 and 5 and the sizes of the engaged plates 30 and 40 may be such that, for example, the lower the ribs 5 and 5 are, the wider the engaged plates 30 and 40 are. . This is because the lower part of the spinal reinforcement band A exerts more force than the upper part thereof, so that the spinal reinforcement band A is reinforced.

FIG. 7 shows a modified example of the cover body 2, in which the cover body 2 is formed to have a length that can be worn from the user's head / neck to the buttocks. Reference numeral 2a is a neck protection cover portion.

FIG. 8 shows the cover body 2 attached with the belt main body 1 over the entire length thereof. With the spinal cord reinforcement A having such a configuration, not only the spine but also the neck can be protected.

In FIGS. 7 and 8, 27 and 27 are neck protection covers.
It is a fastening belt for fixing to the head provided on 2a, and by fixing the fastening belts 27, 27 to the forehead, the neck can be surely protected.

(Second Embodiment) Next, as another embodiment,
What is shown in FIGS. 9 to 12 will be described.

This is also a spinal reinforcement belt A, but when a forward bending posture is taken, a large pulling force is applied to the lower part of the belt body 1 to the rear, so that the fastening belts 24, 24 attached to the cover body,
Only 25,25 may make it difficult to securely fix the spinal reinforcement band A to the body.

Therefore, in this embodiment, the fastening belts 24, 24,
Instead of 25, 25, a fixing band 7 is attached to the band body 1 as a fastening means. Reference numeral 9 is a connecting portion between the band body 1 and the fixed band 7.

As shown in FIG. 11, the fixed band 7 has a structure similar to that of the band body 1 described above, that is, a structure in which two kinds of band component pieces are alternately connected (see FIG. 2) to the back band 72. In addition, the left and right side bands 73 and 74 having the same structure as that of the belt body 1 are continuously connected through the connecting pin 76, and the left and right side bands 73 and 74 can be freely expanded in the left and right direction around the connecting pin 76. I am trying.

Further, a connecting belt 75, to which the surface fastener 26 serving as a fastening portion is attached, is connected to each tip of the left and right side bands 73, 74 via a clasp 77.

The ribs of the fixed band 7 are provided on the body contact surface side of the back band 72, and are provided on the body non-contact surface side of the left and right side bands 73, 74.

In this way, since the fixing band 7 has the same structure as the band body 1, it is possible to follow the movement of the waist and buttocks.

By the way, as shown in FIGS. 9 to 11, the fixing band 7 having the above-described structure has a clasp 77 on the anterior iliac spine b1 of the pelvis b.
It is desirable to fasten them in contact with each other.

That is, as shown in FIG. 12, a large pulling force is applied to the fixing band 7 rearward when it is in the forward bending posture. By fixing the fixing band 7 to the barbs b1 in abutting state, the fixing band 7 can be prevented from bending as much as possible, and the band body 1 can be reliably held.

Therefore, the structural function of the belt body 1 can be sufficiently exerted.

Incidentally, in FIG. 9, FIG. 11 and FIG.
Is a support fitting, and the belt body 1 and the fixed band 7 are connected via the support fitting 71.

The fixed band 7 is also covered with a cloth or the like having the same cushioning function as the cover body 2 in the same manner as the band body 1, and the back band 72 and the left and right side bands 73, 74 are directly attached to the body. They do not come into contact with each other to prevent discomfort.

(Third Embodiment) As yet another embodiment,
The one shown in FIG. 13 will be described.

This is the spinal reinforcement band A in the previous embodiment.
The clip body 8 which bends in the forward bending direction of the spine is connected to the lower end of the band body 1 as a bending assisting means.

That is, in the case where a person often takes a forward bending posture and engages in a special work in which the degree of forward bending is large, in the structure of the second embodiment shown in FIGS. The strength of the connecting portion 9 between the fixing band 1 and the fixing band 7 may not be sufficient.

Therefore, in the present embodiment, the clip body 8 is connected to the lower end of the belt body 1 to form the connecting portion 9, and it is possible to cope with a large degree of bending of the belt body 1. In FIG. 13, 81 and 82 are clip constituent pieces, 83 is a shaft core, and 84
Is a spring.

With such a configuration, even when a large forward bending posture is taken, the belt main body 1 rotates forward about the axis 83 of the clip body 8, so that by setting an appropriate spring constant of the spring 84. While reducing the load on the spine and the muscles of the upper half of the body, the rearward pulling force applied to the connecting portion with the fixing band 7 can be significantly reduced.

As described above, in the spinal reinforcement band A as the reinforcement band according to the present invention, the weight of the upper body is the spine,
Also, since the burden on the ligaments and muscles around it can be reduced as much as possible, it is very effective in treating back pain and correcting the bending and deformation of the spine.

In addition, the spinal cord and each nerve branching from the spinal cord through each vertebra can function properly,
It does not impair the motor function of the whole body, improves blood circulation, keeps the body in good condition including the built-in function, and is effective for promoting health. Moreover, it has neuralgia of the stiff shoulder and upper limbs, back pain, and sciatic bone Also effective in the prevention and treatment of neuralgia.

(Fourth Embodiment) Next, a reinforcement band B for the lower limbs for attaching to the lower limbs to reduce the burden on the knees and calves.
Will be described.

As shown in FIG. 14, this is a belt main body 1 (FIGS. 2 to 2) having a structure substantially the same as that of the spinal reinforcement belt A described above.
(See FIG. 6) is disposed in a cover body 2 formed so that it can be worn on the lower limbs, and the cover body 2 is formed to have a length that can be worn from the upper part of the kneecap to the ankles. 2 is attached over the entire length. 98 is a fastening belt and 99 is a surface fastener.

Further, the band body 1 is separated at the knee contact portion, and a return spring S for urging the band body 1 in the extending direction is arranged at the knee contact portion.

That is, in FIGS. 16 and 17, 90
Is a cut portion of the strip body 1, and the strip body 1 is divided into two at the cut portion 90, and a return spring S is arranged so as to straddle the cut portion 90. In the present embodiment, the cutting portion 90 is provided on the second band component piece 4 which constitutes the band body 1. S1 and S2 are spring ends that abut the divided strip body 1 and restore the strip body 1 bent at the cutting portion 90 to the original stretched state, and S3 is the axis of the return spring S.

With this structure, the reinforcing band B is used not only for bending the knee joint forward and backward, but also for twisting left and right.
Can follow, so that it is possible to eliminate a feeling of discomfort when wearing the reinforcement band B and performing activities.

By using the lower limb reinforcement band B having the above structure, it is possible to reduce the load on the lower limbs without hindering the movement of the knee and lower limb muscles.

For example, when a mid-waist posture in which the knee is bent is taken for agricultural work or the like, especially when such a posture lasts for a long time, not only the thighs of the lower limbs but also the knees and the like become heavy, and Although the muscles of the rattle are also burdened, the load due to the weight can be dispersed and supported by the reinforcing band B.

In particular, an elderly person has a weakened lower limb and is likely to have an orthopedic injury if he / she continues to work as described above, but this reinforcement band B can prevent this. .
