Combined armrest transfer chair

Abstract

A combined armrest transfer chair is mainly composed of a chair frame, balance frames, armrest sets, an armrest lifting device, an armrest propelling device and a control system. The chair frame is composed of a footstock lever, lifting columns, foot frames, a pushing hand, horizontal blocks, stop bars, a front frame, a back frame, a pushing rod and wheel frames. A backrest and a footrest are of a same structure and are symmetrically hinged to the two ends of a seat frame. The gravity center of an arm bed can be regulated by moving the wheel frames. The balance frames are installed on cross frames of the foot frames and used for keeping the arm bed to be not inclined laterally when a human body is transferred. The armrest lifting device is arranged under the bed surface of the arm bed, so that the bed surface of the arm bed is flat and the edges of the arm bed are neat. When a person is transferred to the armchair from a bed, the armchair is changed into the arm bed to be close to the bed, two armrests of each armrest set are alternately inserted into gaps between the person and the bed, go up while the human body is lifted to be immovable, go down and advance until the armrests are inserted into the positions under the human body, and then the person is lifted onto the arm bed. When the person is transferred to the bed, the armrest sets upwards lift the human body to the position over the bed, the two armrests of each armrest set alternately go down and retreat until the person is placed on the bed. Accordingly, a patient can be automatically transferred between the bed and the armchair.

There is an arm-type transfer chair, patent application number: 2015104734780, which imitates the human arm, and two mechanical arm arms are designed side by side to form an arm arm group. One arm support group is equivalent to one arm of a person. The arm group is installed on the seat frame, backrest and footrest of the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method to overcome the disadvantages of the arm-type transfer chair, to solve the problem that when the transfer chair becomes a bed, the lifting device does not protrude above the bed or outside the side of the bed, and prevents the Combination arm transfer chair for bed tipping problems
