Description

A kind of dual-purpose chair

Technical field

The utility model belongs to technical field of furniture manufacturing, particularly a kind of dual-purpose chair.

Background technology

The chair back of chair in the market can't after work very freely leans back become the bed that can take a break, even if having in the market chair can work as bed uses, but its complex structure, the staff who is not suitable for general general office uses, a kind of chair-type bed is disclosed in the open file of publication number CN 201564054 U, it is comprised of handrail, backrest, seat and chair leg, backrest and seat come combination by hinge, backrest and handrail are installed together by the stationary rotary axle, and handrail is connected with seat by the plug-in type bolt.Backrest and seat are realized the conversion of chair and bed by handrail, can realize the sitting and lying exchange function, but this chair need to be sat superincumbent people and leave the seat in the sitting and lying conversion, then operate on it, because operating process meeting egress of chair, will be so that itself with regard to relatively more tired staff, be absorbed in again in the fatigue; The unitary construction of chair also can be so that sit or the people that overlies feels very ill.

The utility model content

The purpose of this utility model provides a kind of dual-purpose chair suitably having a rest after work.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of dual-purpose chair, comprise cushion and backrest, also comprise be used to the support that supports described cushion and described backrest, be provided with dwang between described cushion and the described support, also fix described backrest on the described dwang, a turning cylinder is arranged on the described dwang, at described turning cylinder a bite that described backrest is rotated is arranged.

As preferably, be provided with rotation mechanism in vertical shaft between described cushion and the described dwang.

As preferably, described turning cylinder two ends be provided with make described occlusion portion from control handle, described control handle is controlled simultaneously described backrest and is rotated.

As preferably, described rotation mechanism in vertical shaft is fixed on the described dwang by connecting rod, the rotation by described backrest so that described cushion between 0 °-90 °, rotate.

As preferably, it is oval that described cushion is, and described backrest is in perpendicular the time, and the major axis of described cushion is parallel to described turning cylinder; Described backrest is in horizontal plane the time, and the major axis of described cushion is perpendicular to described turning cylinder.

As preferably, described support is arranged on the end of base.

As preferably, be arranged to cambered surface on the described backrest surface.

The utlity model has following beneficial effect: the people on the seat only needs the control handle behind the backrest is pulled open to both sides, so that the bite on the turning cylinder separately, so that backrest rotates, while cushion rotation direction, become a bed, this chair is simple to operate, can leave the seat just arbitrarily changes between bed and the seat, ellipse setting and the support of this seat cushions are arranged on base end, can guarantee whole chair center of gravity stable when becoming bed, and the cambered surface at backrest place design so that the people on the seat on lying in the seat in, the back is subject to fixedly preventing turning on one's side.
