Sit-to-stand chair

Abstract

The invention discloses a sit-to-stand chair, which comprises a chair bracket, a seat, a rotating frame and a driving mechanism, wherein the rotating frame is used for driving the seat to be inclined relative to the chair bracket so as to assist people on the seat to stand up, and the driving mechanism is used for driving the rotating frame to run. One end of the rotating frame and the top of the chair bracket form a rotating pair, the other opposite end of the rotating frame and one end of the seat also form a rotating pair, and a compound hinge driven by the driving mechanism to rotate is arranged in the middle of the rotating frame. The driving mechanism is used for raising up the rotating pair of the rotating frame and the seat by driving the rotating frame to move around the rotating pair formed by the rotating frame and the chair bracket, and expanding the included angle between the rotating frame and the seat by driving the seat to rotate relative to the rotating frame. During the process of assisting standing up, people can feel that the seat has ascending and rotating trends, the standing-up process is steady, and the final rotating angel of the seat is small, so that the old can be effectively prevented from slipping and falling down. The sit-to-stand chair has a simple structure and is wide in application range.

Description

technical field [0001] The invention relates to a rehabilitation device in the medical field, in particular to an auxiliary standing seat. Background technique [0002] At present, the population over the age of 60 in China has exceeded 132 million, accounting for 10% of the total population of the country. The increasing number of elderly people has become one of the national conditions. The pace of urban life is getting faster and faster. Many young people have no time to take care of the elderly at home, especially the "empty nest", sick, and elderly people. If they are not taken care of, it will affect their life. Life and physical and mental health. With the growth of age, many elderly people have degraded leg strength. Although they can walk, they have difficulty standing up. In view of this phenomenon, it is very meaningful to design auxiliary standing equipment. [0003] In order to solve the above problems, after searching the prior art, it was found that an auxil...

Problems solved by technology

With the growth of age, many elderly people have degraded leg strength. Although they can walk, they have difficulty standing up. In view of this phenomenon, it is very meaningful to design auxiliary standing equipment.

[0003] In order to solve the above problems, after searching the prior art, it was found that an auxiliary standing seat for the elderly (the application number of the Chinese patent is 201520242167.9) adopts the method of using the lifting rod as the power device to push the seat plate to rotate around the seat body, The disadvantage of this method is that only the chair surface is rotated but not lifted during the process of assisting standing up, which will cause the weight of the upper body of the elderly to fall on the knees quickly, and the angle of the chair surface changes quickly, which may easily cause the elderly to fall from the chair. slip and fall
