Arm type automatic transfer chair

Abstract

The invention discloses an arm type automatic transfer chair which mainly comprises a chair frame, a balancing frame, supporting arm groups, a supporting arm lifting device, a supporting arm propelling device and a control system. The chair frame consists of a pedal lever, a lifting column, a foot stand, a pushing hand, a transverse block, a blocking fence, a front frame, a rear frame, a push rod and a wheel carrier. A back rest and a foot rest have the same structure and are symmetrically hinged at two ends of a seat frame. The wheel carrier is moved to adjust the gravity center of a supporting bed, and the balancing frame enables the supporting bed not to lean laterally. The supporting arm lifting device is arranged below the surface of the supporting bed to ensure that the supporting bed has a flat surface and neat edges. A supporting arm is arranged in a secondary slide rail to prolong the supporting and lifting length. When a person needs to be transferred from a bed to an armchair, the armchair is transformed into a supporting bed and is drawn close to the bed. Two supporting arms of each supporting arm group are alternately inserted into a gap between the person and the bed, are ascended to lift the person still, then are descended and are moved forwards until the supporting arms are inserted into a space below the person, and then the person is lifted to the supporting bed. When the person needs to be transferred to the bed, the supporting arm groups uplift the person to above the bed, the two supporting arms of each supporting arm group are alternately descended and drawn back until the person is put on the bed. By using the arm type automatic transfer chair, the person can be automatically transferred between the bed and the armchair.

Description

technical field [0001] The invention relates to a seat, in particular to an arm type automatic transfer chair. Background technique [0002] Existing seats, for people who can move their bodies, can sit on the chair or leave the chair by themselves, can sit and read a book, and go outdoors by themselves or by people. But for people who are sick or have lost the ability to move their bodies, if they want to sit on a chair for a while, they must be supported by one or two people. Especially the people of body weight, it is all very strenuous that a nurse or family nurse help up the chair and get into the bed from the chair, and the patient feels inconvenient. 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 ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method to overcome the disadvantages of arm-type transfer chairs, to solve the problem that when the transfer chair becomes a bed, the arm can transfer human bodies with different bed widths and different positions, and the lifting device does not protrude above the bed. Arm-type automatic transfer chair that does not protrude beyond the side of the bed and prevents the problem of the bed falling over
