The structure of the leg-lifting chair

This creation is a creation of a chair, in particular a modification of the structure of a chair that assists in the use of leg lifts.

According to the human body, the limbs are made up of bones and muscles, and no matter what the action, it will cause a certain burden on the muscles, especially the feet. Even if standing still, the muscles will be fatigued, if not properly relieved. Decompression, after a long period of time, will cause muscle tension and soreness. Especially for women, standing for a long time, or wearing high heels for a day, the legs will be swollen due to poor blood circulation, and even varicose veins, etc., to improve the above situation, in addition to carefully selecting the appropriate shoes, In addition to timely massage of the legs, wearing elastic socks, etc., the most common is to achieve the effect by lifting the legs before going to bed. Lifting the leg movement is to let the blood in the vein return to the soothing effect of improving the edema. As long as the leg is raised above the heart, it will have an effect. In addition, the leg lacing action can improve the softness of the human body. In addition, it also has the effect of increasing blood circulation, eliminating muscle fatigue, relieving muscle pain, and increasing the stretching and reflex effect of the muscles. Therefore, if the leg is lifted at the same time to achieve the effect of pulling the tendons, it is a good stretching exercise. However, for the users who go to work one day, they are very tired when they return home. If they want to engage in this sport again, they often have more than enough energy, so how can the average person sit in a chair to rest or watch TV. The simple mechanism assisted in lifting the legs and pulling the tendons, achieving the purpose of decompression of the legs and promoting blood circulation, has become the direction of the creation of this case. In view of this, the creator has in-depth discussion on the above-mentioned practical creation issues, and actively seeks solutions through years of experience in R&D and manufacturing of related industries. After long-term efforts in research and development, he has finally succeeded in developing this creation. "The structure of the leg-lifting chair" to improve the problem of custom creation.

The main purpose of this creation is to provide a "structure of a leg-lifting lacing chair" which allows the user to sit up on the chair and lift the leg up to about 90 by the aid of the drive unit.
