Chair capable of being unfolded into bed

Abstract

The invention discloses a chair capable of being unfolded into a bed. The chair comprises a chair plate with supporting legs and a rear back plate, wherein clamping grooves are symmetrically formed in two opposite side walls of the chair plate; the two sides of the rear back plate are respectively clamped on the clamping grooves through connecting pieces; an adjusting knob is mounted on each connecting piece; the connecting pieces are hinged between the rear back plate and the chair plate. When the chair capable of being unfolded into the bed is used as the bed, the connecting pieces are unscrewed through the adjusting knobs, so that the rear back plate slides in the clamping grooves until the rear back plate is horizontally arranged, extension plates inside a bed board and the rear back plate are pulled out through sliding rails or opened through flanges, the folded supporting legs mounted on the extension plates are opened to achieve a supporting effect, and people can lie on the chair capable of being unfolded into the bed, so that the problems of lumbar disorders and cervical disorders caused by incorrect resting positions are solved; the chair disclosed by the invention is small in occupied space and saves space.

Description

technical field [0001] The invention relates to furniture, in particular to a chair that can be expanded into a bed. Background technique [0002] The chairs used in the existing office cannot be folded. When the staff is on a lunch break or when they are tired, they can only rest against the back of the chair or lie on the table. The rest posture not only increases the pressure in the cervical intervertebral disc, but also makes the The neck muscles are in a state of uncoordinated stress for a long time, the muscles and ligaments at the back of the neck are susceptible to stretching and strain, and the front edges of the vertebral bodies wear and proliferate each other, coupled with excessive torsion and lateral flexion, which further leads to injury and cervical spondylosis. , causing serious impact on people's health; for this reason, the inventor invented a chair that can be expanded into a bed after painstaking research. The board is converted into a horizontal state, ...

[0002] The chairs used in the existing office cannot be folded. When the staff is on a lunch break or when they are tired, they can only rest against the back of the chair or lie on the table. The rest posture not only increases the pressure in the cervical intervertebral disc, but also makes the The neck muscles are in a state of uncoordinated stress for a long time, the muscles and ligaments at the back of the neck are susceptible to stretching and strain, and the front edges of the vertebral bodies wear and proliferate each other, coupled with excessive torsion and lateral flexion, which further leads to injury and cervical spondylosis. , causing serious impact on people's health; for this reason, the inventor invented a chair that can be expanded into a bed after painstaking research. The board is converted into a horizontal state, and the folded legs at the bottom of the extension board are opened to play a supporting role, and the chair becomes a bed for people to lie on and rest on the bed
