Description

  The present invention relates to a stretch device.

  Currently, many people live a life that places a strain on the waist by desk work and sports that keep sitting in a chair for a long time. Such a life causes back pain because an unbalanced force is applied to the lumbar vertebrae and intervertebral disc and the central nerve is compressed. Therefore, various health promotion tools have been proposed as countermeasures for back pain.

  For example, Patent Document 1 proposes a T-shaped health enhancer that includes a flat plate portion and a back member that protrudes from the back surface of the plate portion. The health promotion tool is placed on the floor so that the tip of the back member reaches the floor surface. In this state, the plate portion extends laterally on the upper side of the back member. The user rests on the plate portion in a supine posture, and pushes down one end portion of the plate portion with the tip of the foot. Then, the other end of the plate portion is pushed up like a seesaw with the back member as a fulcrum according to the principle of leverage. Thereby, a user's waist | hip | lumbar part is pulled up and the muscles of a waist | hip | lumbar part are pulled.

  However, in the device of Patent Document 1, the height at which the waist is pushed up is determined according to the force of the toes that pushes down one end of the plate, so that elderly people with weak foot strength can push up the waist sufficiently. It was not possible to obtain a large stretch effect. In addition, it was difficult to apply force because the plate had to be pushed down with the tip of the foot, and it was necessary to always step on the foot during stretching exercises. Moreover, since the plate portion immediately moved when the force of the foot was removed, it was not stable and difficult to repeat the stretching exercise.

  The present invention has been made to solve the above-mentioned problems, and even a user with weak foot strength can obtain a large stretch effect without straddling the foot, and can stably stretch the waist. Provide a stretch device that can.
