Abstract

PROBLEM TO BE SOLVED: To provide a lower back pain prevention supporter which supports a body by resilience of elastic materials bending upon working in a stooped posture, allows easy return by force of the elastic materials upon returning a posture to the origin, has a simple structure, does not have hindrance to work when a worker wears pants on the supporter as underwear since a structure avoids a crotch part, is lightweight, and is usable for nursing care.SOLUTION: The lightweight lower back prevention supporter is obtained by positioning a pair of elastic materials 1 on right and left side faces of the pelvis, and connecting the elastic materials by a plurality of belts 4-6 avoiding the crotch part, so that the worker can easily work in the stooped posture wearing the pants after wearing the supporter as the underwear.

Description

      Supporter to prevent back pain.

      Conventionally, there has been a problem that low back pain occurs in farm work, cargo handling work, and care involving work in a forward bending posture, and as a countermeasure, a belt that is wound around the waist or pelvis has been mainly used. However, it was insufficient as a countermeasure for back pain.

          In addition, there is a product that has been developed as a power assist suit. However, since it is large and expensive, there is a difficulty in practical use in the field. Therefore, in the nursing care field, in consideration of usability, there is a demand for an object that is inexpensive, has a simple structure, and can be worn in a manner such as underwear.

      Although the following is proposed as a prior art document, since Patent Document 1 has a complicated structure for generating spring stress, the cost increases and the risk of failure increases. In addition, there is a complexity in wearing on the body, and there is a concern that a care worker and a care service user who often have structures in close contact with each other may feel uncomfortable, making it difficult to use for care. is there.

    Since Patent Document 2 is a method of actively lifting the upper body, the effect is outstanding, but the place of use is limited, and the cost increases, which is not practical. In Patent Document 3, the effect of causing the upper body from the back can be expected to have a slight effect, but the body above the pelvis has a slight degree of flexion, and thus the action of force is only slightly generated. In Patent Document 4, when the upper body is tilted forward, the force for pushing up the upper body is small and the effect is small. Patent Document 5 has only an effect of stimulating the waist, and has a slight effect of pushing up the upper body of the forward bending posture.

    Those shown in the above and other patent documents are limited to places where they are used, cost is high, and effects on the forward bending posture are insufficient. The invention is intended to solve the problem that the cost is low, the place of use is not limited, it is highly practical, especially for caregivers who support an aging society, and an easy to bend forward posture while wearing as underwear. It is a problem.

    The present invention is characterized in that a pair of elastic members are disposed in a portion from the pelvic side surface portion to the thigh side surface portion, and each of them is connected by a pair of belts intersecting each other while avoiding the crotch portion and two substantially parallel belts. It is a back pain prevention supporter.

      The back pain prevention supporter according to the present invention has a simple structure and is easy to wear. The elastic material bends when working in a forward bending posture and supports the body by its restoring force. It can be easily returned by force. Furthermore, since the elastic material is connected by a few belts, it is lightweight, and since the belt avoids the crotch part, there is no hindrance to the work of wearing pants on wearing as underwear.

    In addition, the structure does not give a sense of incongruity to the other bodies that are in close contact with each other, and can also be applied to caregivers.

Embodiments will be described below with reference to the accompanying drawings.

      In FIG. 1, reference numeral 3 denotes a bendable elastic material insertion sheath, which is provided as a pair on the left and right. In the elastic material insertion sheath 3, the elastic material 1 is held by elastic material holders 2 provided at the upper and lower ends thereof. Abdominal tension belts 5a and 5b are attached to the upper portions of the respective elastic material insertion sheaths 3, and connecting tapes 8a and 8b are provided at the ends thereof. Crotch tension belts 6a and 6b are attached to the lower part of the elastic material insertion sheath 3, and connecting tapes 9a and 9b are provided at the ends thereof. Further, back tension belts 4a and 4b are attached to the central portion of each elastic material insertion sheath 3, and connecting tapes 7a and 7b are provided at the ends thereof. Further, the connecting tapes 10a and 10b are provided at the opposite ends, and the connecting tapes 11a and 11b are also provided in the elastic material insertion sheath 3 in the vicinity thereof. The connecting tape can be replaced with a buckle.

      2, 3 and 4 show the back pain prevention supporter attached to the body. The abdominal tension belts 5a and 5b are pulled toward the abdomen and connected by connecting tapes 8a and 8b provided at the respective ends. Match. The back tension belts 4a and 4b are pulled around the back of the pelvis and turned around and connected by connecting tapes 7a and 7b provided at the respective ends. The crotch tension belts 6a and 6b are pulled forward, and are connected to the connecting tapes 10a and 10b of the back-side tension belts 4a and 4b attached to or near the connecting tapes 11a and 11b of the elastic material insertion sheath 3 on the opposite side. Connect together. By doing so, the elastic member 1 is positioned on the left and right side surfaces of the pelvis, the center thereof is pulled rearward by the rearward tension belts 4a and 4b, and the upper and lower abdominal tension belts 5a and 5b and the crotch tension belts 6a and 6b. Thus, the elastic material 1 and the elastic material insertion sheath 3 are bent rearward. Adjust the tensile strength of each belt as necessary.

      FIG. 5 shows another embodiment in which a back extension belt 12 having a tightening effect is wound around the waist, and an anti-slip belt 13 is wound around the thigh below the hip joint. The performance of the back pain prevention supporter will be further improved.

      FIG. 6 shows the back bend posture with the back pain prevention supporter according to the present invention. At this time, the bent elastic material 1 reduces the burden on the bent waist, and the elastic material 1 is elastic when stretched. Easy to use.

      FIG. 7 shows another embodiment of the back pain prevention supporter of the present invention.

    This is a method in which the crotch tension belts 6a and 6b are pulled forward, and the connecting tapes 9a and 9b at the tips thereof are joined at the lower abdomen.

    In this method, since the elastic material 1 and the lower part of the elastic material insertion sheath 3 are bent forward and upward due to the pulling force, the connecting tapes 9a and 9b can be joined together in the lower abdomen, and the mounting work is easy. It is.

      FIG. 8 shows an embodiment in which the lower back pain prevention supporter of FIG. 7 is mounted, and the function of supporting the body can be generated by the restoring force of the elastic material 1 curved in the forward bending posture in almost the same manner as FIG.

      In the elastic material 1 applied to the present invention, the iron-based spring material causes permanent deformation beyond the elastic limit when the body is largely bent forward. Therefore, when applying the shape memory alloy and applying the superelastic property, the spring Therefore, it is comfortable and effective because there is no generation of excessive stress and there is little increase in pressure on the body.
