Abstract

PROBLEM TO BE SOLVED: To provide a lumbar band which can be tightly fastened when necessary, and can give tightening force not so strong enough to make a user wearing the belt for a long time feel painful, allowing the user to move freely to some extent, and can be attached quickly and easily at a prescribed position. SOLUTION: This lumbar band consists of the band main body 1, fastening belts 3, 4, and a hanging belt 5. The band main body 1 consists of an elastic part 6 (to which a pad is fixed) with the width L made of an elastic material, and non-elastic parts 7 and 8 made of a non-elastic material continuing from the elastic part 6 to both free ends. The ends of a pair of fastening belts 3 and 4 are fixed to the ends (b) of the non-elastic parts 7 and 8 respectively to the center side. When the band is used, free ends of the non-elastic parts 7 and 8 are tentatively fixed to each other with hook-and-loop fasteners, then second belts 17 and 18 are pulled, and the ends of the second belts are fixed to the band main body 1 with hook-and-loop fasteners.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lumbar spinal cord (corset) used for treating and preventing recurrence of low back pain or preventing low back pain.

[0002]

2. Description of the Related Art For example, caregivers taking care of the elderly or the physically handicapped, workers who often carry heavy objects, etc., have an opportunity to lift or support a heavy object while leaning down. Because of the large burden on the lower back, many people complain of lower back pain. For the purpose of treating back pain, preventing recurrence, and preventing back pain in these people, it is recommended to use a lumbar band that is wrapped around the waist and tightened.

[0003] As a lumbar vertebral band which can be used for such purpose, there is, for example, a band for treating back pain described in Japanese Utility Model Publication No. 52-7115 (commercially available). This lumbar vertebral band (band for treating back pain) has a band-shaped main body portion (sacroiliac band) having a pad attached to a central portion thereof, and a pair of fixed end portions at positions separated from the pad of the band-shaped main body portion by a predetermined width. A fastening belt (fastening strap, ring and stopper strap) is provided, and the belt-shaped main body is wrapped around the waist so that the pad is on the back side, and the pair of fastening belts pass over the pad and face in a direction opposite to each other. And the band-shaped main body is fastened to the waist. At the time of mounting, first, the band-shaped main body portion is wrapped around the waist by placing the pad on the back side, the buttons at both free ends of the above-mentioned band-shaped main body portion are stopped, and then the pair of fastening belts are pulled forward to pull the band-shaped main body portion to the waist portion. At this time, the folded portions formed on both sides of the pad are pulled closer to each other by being pulled by the fastening belt, and the entire belt-shaped main body portion excluding the folded portions is tightened around the waist portion, and the accompanying tightening is performed. The surplus length is absorbed by the folded portion.

[0004]

By the way, if the lumbar band is worn tight for a long time,
Desirably, it can be mounted slightly loose. In addition, at the point of care, etc., it is actually necessary to tighten tightly when lifting a heavy object, but it is usually better to use a relatively loose tightening force and not to restrict free movement.

However, since the conventional lumbar belt-like main body is made of a material having substantially no elasticity over the entire length of commercially available lumbar vertebrae, the lumbar vertebral band is not squeezed when the tightening belt is tightened. Although it has a function to securely support, but it is still painful if you wear it for a long time, it will be easier if you remove the fastening belt, but as it is, it will slip down and the fastening power will not be applied to the waist, so it has no meaning as a lumbar vertebral band However, when the belt is loosely mounted, it is easier to do so, but there is a problem in that the belt-shaped main body has no elasticity, so that free movement is restricted. In addition, it is necessary to fasten the tightening belt while holding down the hand so as not to cause a displacement at the time of wearing, which causes the lumbar spine belt to be loose when worn.

[0006] In addition, at the point of care, etc., the lumbar spine belt is always worn, and the lumbar spine belt is elastic so that it can be worn immediately when needed. Is considered to be attached. In this case, it is considered that the lumbar belt is usually suspended at a position slightly above the mounting position, and is pulled down to a predetermined position when mounting. When the suspension belt is applied to the above-mentioned conventional lumbar belt, the lumbar belt is pulled down to a predetermined position, held down by hand, and the tightening belt is tightened in this state, but the lumbar belt is attached upward due to the elasticity of the suspension belt. There is a problem in that, since it is urged, it is likely to cause a positional shift, and it is difficult to mount it at the predetermined position as described above.

[0007] The present invention has been made in view of the above-mentioned problems of the conventional lumbar vertebrae, and can be tightened tightly when necessary, for example, when lifting a heavy object. It is an object of the present invention to apply a tightening force at a level that does not cause a burden, and to allow a certain degree of free movement. At the same time, it is an object of the present invention to enable the lumbar belt to be quickly attached to a predetermined position as needed.

[0008]

According to the present invention, there is provided a belt-shaped main body having a pad attached to a central portion thereof, and a pair of tightening belts having ends fixed to the belt-shaped main body. Is wound around the waist so that it comes to the back side, and the pair of tightening belts are wound around the pad in the opposite direction toward the front toward the front, so that the belt-shaped main body is fastened and mounted on the waist. At least portions on both sides of the pad of the band-shaped main body portion are made of a material having elasticity over a predetermined width, and portions up to both free ends following the portion are made of a material having substantially no elasticity. Each of the end portions of the tightening belt is fixed to the center side end portion of the portion made of the substantially non-stretchable material or in the vicinity thereof.

[0009] If necessary, a suspending belt for suspending from the shoulder can be attached to the lumbar spine belt. In addition, an attachment member for detachably attaching belts for carrying can be attached to the tightening belt of the lumbar vertebra as necessary. Here, the belts for carrying cargo mean belts and nets that can be wrapped around the load and fixed at both ends of the worker's shoulders and waist so that heavy loads can be lifted by the whole body. It is a well-known tool. In this lumbar vertebrae band, the pair of tightening belts are inserted into a first belt having both ends fixed at or near the central end of one non-stretchable portion to form a loop, and the first belt is inserted through the first belt. Ring, and one end is fixed at a position near the center or the free end of the other non-stretchable portion, and can be constituted by a second belt inserted through the ring. It is good to attach to the first belt.

[0010] As a method of fixing both the free ends of the lumbar vertebral band and the fastening belt, hook-and-loop fasteners which are engaged with each other are attached to the both free ends, and the two free ends are fixed to the abdomen by these hook-and-loop fasteners. A hook-and-loop fastener is attached to the front side of both free ends, and a hook-and-loop fastener that engages with the hook-and-loop fastener is attached to the fastening belt, and the fastening belt is fixed to the abdomen by these hook-and-loop fasteners. Or, a hook-and-loop fastener is attached to the front side of both of the free ends, and a hook-and-loop fastener that engages with the front-side hook-and-loop fastener of the other free end is attached to the back side of one of the free ends. And
It can be specifically mentioned that a hook-and-loop fastener that engages with a hook-and-loop fastener on the front side of the free end is attached to the fastening belt.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of a lumbar vertebra according to the present invention will be specifically described with reference to FIGS. The lumbar spine band includes a band-shaped main body 1 wound around the waist, and the band-shaped main body 1.
A pair of fastening belts 3 and 4 whose ends are fixed at positions separated from the pad 2 by a predetermined width, and a suspension belt 5.

First, as shown in FIGS. 1 and 2, the band-shaped main body 1 is composed of a stretchable portion 6 wider (width L) than the pad 2 and non-stretchable portions 7 and 8 on both sides thereof. Are sewn to the non-stretchable parts 7, 8 at the vertical line a,
The telescopic part 6 and the non-telescopic parts 7, 8 overlap by the width of W.
The elastic portion 6 is made of an elastic and flexible material, and a pad 2 having a width S is attached to a central portion on the back side. Therefore, the part which expands and contracts substantially is the part of width (LS). The non-stretchable portions 7 and 8 are made of a material that has substantially no stretchability and is slightly harder than the stretchable portion 6, such as cotton cloth and artificial leather. Further, hook-and-loop fasteners 9 and 10 are attached to the front sides of both free ends of the band-shaped main body 1 (non-stretchable portions 7 and 8), and the free ends of the non-stretchable portions 7 are provided behind the free ends of the non-stretchable portions 8. The hook-and-loop fastener 11 which engages with the hook-and-loop fastener 9 on the front side is attached.

The tightening belts 3 and 4 have first and second belts 13 and 14, both ends of which are sewn to the center end b of the non-stretchable portions 8 and 7 to form loops. Rectangular rings 15, 16 through which
And one end is sewn near the center of the non-stretchable portions 7 and 8 (position near the ends of the hook-and-loop fasteners 9 and 10), and the second belts 17 and 18 inserted through the rectangular rings 15 and 16.
Consisting of substantially no elasticity. The first belts 13, 14 extend in opposite directions over the pad 2, and then pass through the second rings 15, 16 via the rectangular rings 15, 16.
Belts 17 and 18 extend toward the free end, and constitute a pair of tightening belts 3 and 4 as a whole. here,
When the other ends of the second belts 17 and 18 are pulled in opposite directions (the free end side in FIG. 1 or FIG. 2), the first belts 13 and 18 are pulled out.
14 is pulled right and left, and the ends of the first belts 13 and 14 act to bring the sewn non-stretchable portions 8 and 7 inward (see arrow c). In addition, the hook-and-loop fastener 9 or 10 is provided on the back side of the other ends of the second belts 17 and 18.
The hook-and-loop fasteners 19 and 20 which engage with are provided.

The suspension belt 5 is a belt 5 having three elasticities.
a to 5c are connected to one place, and the central belt 5a
Is fixed to the upper end of the telescopic part 6 via a rectangular ring 22, and the belts 5b and 5c on both sides are rectangular rings 23 and 2
4 and is fixed to the upper ends of the non-stretchable portions 7 and 8 and a loop is formed between the metal fittings 25 and 26 and the rings 23 and 24. By moving the metal fittings 25 and 26 along the length direction, the length is increased. It is adjustable.

Next, the procedure for mounting the lumbar vertebrae will be described with reference to FIGS. First, the lumbar belt is hung by hanging the suspension belt 5 on the shoulder, and when the lumbar belt is worn, the lumbar belt is pulled down to a predetermined position, the pad 2 is placed on the lumbar spine on the back side, and the lumbar region is wound around the lumbar region. It is temporarily fixed at that position by the fasteners 9 and 11 (see FIGS. 3 and 4). In this state, the force for tightening the waist portion depends only on the elasticity of the elastic portion 6.

Subsequently, the left and right fastening belts 3 and 4 (second
When the belts 17, 18) are pulled forward, the fastening belt 3
The non-stretchable portion 8 is drawn by the (second belt 17),
Non-stretchable part 7 by fastening belt 4 (second belt 18)
, The distance between the center-side ends b, b of the non-stretchable portion becomes narrower (M → N), and the waist becomes tight. As the distance between the center-side ends b, b of the non-stretchable portion becomes narrower (that is, as the center-side ends b, b move), both sides of the stretchable portion 6 are positioned below the non-stretchable portions 7, 8. The portion is drawn into a double fold (the portion is indicated by arrow d), and the excess length is absorbed as in the conventional example (see FIGS. 5 and 6). At this stage, when the hook-and-loop fasteners 19 are attached to 9 and 20 are attached and fixed, the waist is tightened by the non-stretchable non-stretchable portions 7 and 8 and the tightening belts 3 and 4. Similarly, it is surely supported.

As a method of using the lumbar vertebral band, for example,
Always use it simply by hanging it from your shoulder and wear it when you need it, or always use a tightening belt instead of using a tightening belt and temporarily tighten it when you need it. It is possible to use it. It should be noted that even in a temporarily fixed state, it has a function of supporting the waist and is only fastened by elasticity, so that free movement is allowed. In any case, since it can be temporarily fixed at a predetermined position before being fastened by the fastening belt, it can be quickly mounted at an accurate position.

FIGS. 7 and 8 show another example of the lumbar vertebral band, and a pair of mounting members 28,
29 (the first belts 13 and 14 are inserted through the mounting openings at the rear ends of the mounting members 28 and 29). The other points are the same as those of the lumbar vertebrae shown in FIGS. The mounting members 28 and 29 are provided with a carrying belt 30.
Can be engaged with the corresponding attachment members 31 and 32 attached to both ends of the belt, and can be easily attached and detached.
Is easy to install or remove. The shapes and structures of the mounting members 28, 29, 31, and 32 shown here are well known, and the mounting members 31 and 32 are
Engagement is achieved by simply inserting (arrows e) into the mounting members 31 and 32 and engaging portions 31a, 31a, 3
1b and 31b may be pushed in (arrow f direction).

After attaching the lumbar belt, the unloading belt 3
If 0 is used, it is easy to carry or support a heavy load or a cared person, and at this time, the mounting members 28, 2
9 is attached to the fastening belts 3 and 4 (the first belts 13 and 14), so that the fastening belts 3 and 4 (first
Since a load is applied to the belts 13 and 14), and this load acts in a direction to tighten the lumbar vertebrae, the abdominal pressure effect by the lumbar vertebrae is further increased, and the burden on the waist does not need to be increased.

[0020]

According to the present invention, it is possible to increase the abdominal pressure effect by tightening tightly as necessary, for example, to reduce the burden on the waist when lifting heavy objects, and to wear it for a long time when it is not particularly necessary. It is possible to apply a tightening force at a level that does not cause a burden even if the user is doing it, and it is possible to obtain a lumbar vertebrae in which free movement is allowed to some extent. At the same time, since the temporary fixation can be performed, the lumbar belt can be accurately and quickly mounted at a predetermined position. Also, if the mounting member for detachably attaching the belts for carrying is attached to the tightening belt, and the belts are attached to this to carry or support a heavy load, the load increases the abdominal pressure effect of the lumbar vertebral band. The burden on the waist is further reduced.
