Standing assisting chair for old people

Abstract

The invention discloses a standing assisting chair for old people. The standing assisting chair comprises chair bodies and a seat plate, wherein the space between the seat plate and a plate at the lower portions of the chair bodies is internally and fixedly provided with a scissors fork mechanism, the scissors fork mechanism is symmetrically distributed, the upper and lower ends of the left and right sides of the scissors fork mechanism are all fixedly provided with a slide rail, the slide rails are provided with sliding blocks, the left and right sides of the scissors fork mechanism are bothprovided with a pair of cross-distributed scissors fork links, the upper and lower ends of the scissors fork links are connected with the sliding blocks respectively, the sliding blocks are further connected with a crank sliding block mechanism, and a tension spring is connected between the top end of the crank sliding block mechanism and the chair bodies; the top of the scissors fork mechanism isfurther fixedly provided with a roller, and the roller is in contact with the seat plate. The standing assisting chair has the advantages of pure mechanical structure, convenient maintenance, simpleoperation, simple structure and strong adaptability, and is suitable for indoor places and outdoor places with frequent use and complicated environment.

Description

technical field [0001] The invention relates to an auxiliary standing chair, in particular to an auxiliary standing chair for the elderly. Background technique [0002] At present, there are many auxiliary products to help the elderly to get up and stand in view of the difficulty in standing for the elderly. Most of the existing auxiliary standing chairs use electric push rods and hydraulic push rods to push the seat board up to help the elderly get up, but This method requires power supply, which is not convenient to put in outdoor areas such as parks and squares without power supply facilities, and has high environmental requirements and requires regular maintenance. Compared with purely mechanical products, the reliability and stability are poor; The spring is directly used as the pushing device, but the elastic force of the spring will change greatly with the change of the stroke, so that the stability is poor during the whole process of assisting the elderly to stand. ...

AI Technical Summary

Problems solved by technology

[0003] Purpose of the invention: The purpose of the invention is to solve the problems that the existing auxiliary standing chairs use electric push rods, hydraulic devices and other electrical devices, which are troublesome to maintain, require external power supply, and cannot be installed in outdoor places without power supply facilities, and when springs are directly used as thrust devices. , the problem that the thrust will change greatly with the stroke provides an auxiliary standing chair for the elderly that is easy to maintain, does not require a power source, has wide applicability, and is stable and comfortable when used.
