Description

  The present invention belongs to the field of exercise equipment that exercises legs and the like, and particularly relates to an exercise equipment for legs that enables movement of legs in a sitting state.

  Leg exercise associated with walking, stretching, etc. is effective in relieving lack of exercise, improving health, recovering from fatigue, improving physical fitness after sickness, etc., and has attracted particular attention in recent years. For this reason, various exercise devices for legs that can be used easily indoors have been developed and used.

  An example of such a leg exercise device is a stepping exercise machine disclosed in Patent Document 1. This exerciser is called a so-called stepper, and its structure allows a stepping motion alternately by placing the feet on a pair of left and right pedals with the toe side as a pivot point. Further, a load is applied when the pedal is stepped on, and each muscle and knee of the user's leg can be trained.

In addition, as shown in Patent Document 2, a foot health device is disclosed that trains leg muscles and the like and promotes health in a sitting state. This health device has a structure in which a coil spring is arranged in parallel on the upper surface of the base, and a pair of left and right pedals are fixed on the coil spring. The user can place his / her foot on the pedal and sit down on a chair or the like to perform leg movement.

  However, the stepping exercise machine of Patent Document 1 must be used in a standing posture, and is particularly continued for persons with disabilities or elderly persons (hereinafter referred to as “elderly persons”). There were dangerous aspects that were difficult to use. In addition, since the overall weight of the user is supported by a stepping exercise machine, this exercise machine is made of a highly rigid material and frame in consideration of safety, and can be easily moved or carried around. The weight was unreasonable.

  The foot health device of Patent Document 2 has an advantage that it can be used in a sitting state, but because of the structure in which the pedal placed on the coil spring is structurally depressed, the stepping force is easily dispersed and the reaction load is weak. The effect was also limited to the muscles below the knee. For this reason, aside from elderly people with extremely weak muscular strength, there is a problem that healthy people cannot perform efficient exercise of the entire leg. Further, it is bulky and inconvenient because of the configuration in which two large coil springs are arranged to be carried and used at an appropriate place.

  In recent years, pulmonary thrombosis, a so-called economy class syndrome, that is likely to occur when a passenger sits on a narrow seat in the same posture for a long time when boarding an aircraft, has become a problem. For this reason, there has been a demand for an exercise device for legs that allows a healthy person to efficiently exercise and stretch the legs while sitting, and to prevent this economy class syndrome.

  Accordingly, the present invention has been made in view of the above-mentioned problems, and provides a leg exercise device that can be easily carried and can be exercised by the entire leg efficiently even in a sitting state. To do.

In order to solve the above-described problems, the leg exercise device of the present invention is configured as follows.
