Abstract

The invention discloses a standing-assisted chair with lifting devices. The chair comprises a chair frame, a motor, second transmission shafts and two lifting devices, wherein the chair frame is provided with front support legs and second cross beams; the second cross beams are connected with the back of the chair frame and upper ends of the front support legs; the two lifting devices are respectively fixed on two armrests, wherein first transmission shafts are hinged to the second cross beams; backstops are fixed on the second cross beams; lower ends of second connecting rods are hinged to front ends of the second cross beams; the second transmission shafts penetrate through two driving wheels in the two lifting devices, and second transmission wheels are driven by the motor. According to the standing-assisted chair with the lifting devices disclosed by the invention, the lifting devices are driven by the motor to drive a person who inconveniently stands up to stand up; through the arrangement of the backstops, the lifting devices are prevented from turning downwards, the heights of lifting frames can be adjusted in a certain range so as to be matched with persons of different heights; by adjusting the lengths of telescopic rods and synchronous rods, a distance between the two lifting frames is adjusted to be matched with persons of different shoulder widths.

Description

technical field [0001] The invention relates to the technical field of living and home furnishing, in particular to an auxiliary rising chair with a lifting device. Background technique [0002] Chairs have become people's daily necessities in daily life. When people sit on a common seat and want to get up or sit down, they need the support of the leg muscles to complete the action. However, it is more difficult for the elderly or those with weak leg muscles to complete this action. Elderly people or people with weak leg muscles need external force to get up and sit down. [0003] The invention patent with the existing publication number CN104274283B is a chair for assisting sitting up, which includes a parallelogram mechanism composed of a chair surface, a connecting rod, a connecting rod and a rocking bar, and a rocker composed of a chair body, a slider, a connecting rod and a rocking bar. Rod slider mechanism. The two mechanisms are combined into a six-bar mechanism. ...
