JPS5828580Y2 - Posture correction equipment for sitting cross-legged or sideways - Google Patents

Description

[Detailed explanation of the invention] This invention is based on the fact that when Japanese people sit cross-legged or sideways, which is the customary way of sitting for Japanese people, unreasonable stress is placed on the human body from the sacrum to the lower back due to the skeletal structure, which has a negative impact on the human body. This article relates to a new posture correction tool that was developed with the aim of eliminating the cause of this problem.

Japanese people generally sit in the following ways, except for special seats:
The custom of sitting cross-legged for men and cross-legged for women has become established, and even in today's Western-style living environments where carpets are often carpeted, people tend to settle into their habitual sitting positions. be.

This posture not only has a negative impact on the skeletal structure of Japanese people, especially those of the younger generation, but also causes chronic lower back pain, internal organ disease, and effects on the nervous system in adults of both sexes. Although it can never be a happy state, it has become an inseparable habit in daily life outside the home, such as family life and gatherings.

Therefore, this idea addresses these circumstances and aims to reduce the influence of the lumbar vertebrae, sacrum, etc. on the vertebrae even when sitting cross-legged or horizontally, thereby eliminating the negative effects on other human body organs as much as possible. He developed and researched posture correction equipment and succeeded in putting it into practical use.

The details of the configuration will be described below with reference to the drawings.

As can be understood from the overall perspective view shown in Figure 1, the posture correction device of this invention is suitable for the back part of the human body from the sacrum to the lumbar vertebrae when the person is sitting cross-legged or sitting on his side. Generally speaking, there is a contact seat 1 that comes into contact with the hip bone or a slightly upper position of the hip bone and stably fixes that part in the left and right direction over a predetermined width, and both left and right ends of the contact seat 1. This is a posture correcting tool for correcting posture in a crouched or side-sitting posture with fixing bands 2, 2 extending symmetrically from the fixing bands 2, 2 having support parts 21 that can be fixed near each kneecap in a cross-legged or side-sitting posture.

As can be understood from FIGS. 1 to 3 or 4, the abutment seat 1 stably abuts and fixes a predetermined width of the back of the human body from the sacrum to the lumbar vertebrae. Therefore, it would be convenient to use a flexible material made of a somewhat thick rubber plate or plastic plate, leather, thick cloth, etc. alone or in combination. Depending on the case, it is also possible to use a corset-like molded body.

The width of the contact seat 1 is most effective if it is about 10 to 15 cm, but it is not necessarily limited to this value, and it is possible to select an appropriate width depending on the size of the body etc. Of course.

As can be seen in the illustrated example, the acupressure plate 11.11 having a protrusion 12.12 formed on the inside is attached to the abutment seat 1, and is formed so that its position can be changed as appropriate. You can also leave it there.

The fixing bands 2, 2 extend from both left and right ends of the abutment seat 1, respectively, and their shape is similar to that of the embodiment shown in FIGS. 1 to 3. A pair of bands are stretched separately from the top and bottom of the ends, a fastener 22 is attached to one of the bands, and the band is assembled to the other band.
A closed band of a required length may be formed, and the end opposite to the contact seat 1 may be used as a support portion 21, or alternatively, a closed band of a required length may be formed. One band may be stretched from both left and right ends, passed through a length adjuster 23 in the middle, and then a hemispherical or bifurcated support portion 21 is formed at the tip.

As for the material, it is more advantageous to use a rubber material that has the property of being able to expand and contract within an appropriate range, rather than something that is only flexible, such as synthetic leather, leather, or thick cloth. Become.

Furthermore, acupressure plates 24, 24, such as those formed on the abutment seat 1, can be loosely fitted into the support portions 21 of the fixing bands 2, 2.

Furthermore, in the part of the support part 21 that directly contacts the kneecap,
It is also possible to make it separate from the above-mentioned acupressure plate 24, 24, and to have a pressure-contact buffer band 26, 26 in which a large number of protrusions or flocked protrusions 27, 27 are formed. .

The posture correction tool of this invention, which has the above-mentioned configuration,
First, the abutment seat 1 is brought into contact with a predetermined position on the back of the human body from the sacrum to the lumbar vertebrae while sitting cross-legged or sideways.

At this time, if the acupressure plate 11.11 is provided on the abutment seat 1, place the acupressure plate 11.11 at the appropriate position on the left and right of the vertebral central axis where the muscles bulge. The protrusions 12, 12 of the acupressure plate 11.11 are designed to hit the pressure points for acupressure.

Next, the fixing bands 2, 2 at the left and right ends of the abutment seat 1 are guided toward the kneecap, respectively, so that each support part 21, 21 is hooked on the kneecap or its vicinity. The fixing bands 2, 2 must be adjusted appropriately using the fasteners 22, 22 or the length adjusters 23, 23 provided on the fixing bands 2, 2 until it feels like it is pressed against the back waist of the human body with a moderate pressure.

Furthermore, if pressure-contact buffer bands 26 and 26 are provided, by moving them to the area where pressure is felt most, such as the kneecap or its vicinity, the fixing bands 2, 2 can be adjusted slightly shorter and the human body can be removed from the abutment seat 1. Even when the pressure is applied to the back lumbar region, the feeling of pressure on the kneecaps is alleviated, and the kneecaps do not sweat even when used in the summer or while soaking in a kotatsu. You can prevent things like this from happening.

When the fixing bands 2, 2 are provided with acupressure plates 24, 24, they are naturally adjusted, and pressure points near the kneecap,
For example, by abutting the protrusions 25, 25 on the thighs or the inner thighs, it is possible to expect acupressure effects on the legs as well as on the lower back of the human body.

When the posture correction device of this invention is fixed to the human body in this way, the lumbosacral angle (i.e., the angle between the lumbar vertebrae and the sacrum, the optimal angle is about 30 degrees), which tends to collapse when sitting cross-legged or sideways.
It is said that

).

In other words, the tip of the extremely strong femur, the kneecap or its vicinity, becomes a support point that prevents the lumbar region of the human body from curving from the lumbar vertebrae to the sacrum, similar to the lumbar protection band worn by weightlifters. It is something that fulfills a function.

Moreover, unlike this waist protection band, it does not put pressure on the entire torso at all, and the pressure on the back of the human body can be varied by moving the kneecap up and down or left and right (fixing band). When 2, 2 are made of a stretchable material, this tendency becomes even more pronounced), making it extremely convenient for long-term use.

In this way, as a result of its protective function, it is able to protect against the deformation of the vertebrae that tends to occur when sitting cross-legged or sideways.
It eliminates the disadvantages of skeletal formation that are said to be unique to Japanese people, and is therefore effective against chronic lower back pain, which is said to be caused by skeletal deformation, as well as internal organ disorders and neurological disorders. The synergistic effect is immeasurable because it is possible to expect acupressure effects by using the pressing force of the fixing bands 1 and 2 on the human body contact surfaces. It can be said.

In addition, as another method of using this posture correction tool, the supporting parts 21 and 21 of the fixing bands 2, 2 are supported directly on or near the kneecap, and only the length is adjusted so that the abutment seat 1 can be placed on either side. If the kneecaps are moved up and down alternately after touching the shoulder of the patient, it can also be used as a massage tool for the shoulder. By adjusting the length of the fixing bands 2, 2 and hooking the support portions 21, 21 on the arch of the sole of the foot to stretch the foot, the device can also be used as an acupressure tool for the sole of the foot.
