Folding chair

Abstract

The invention relates to a folding chair, which comprises a seat tube, a back pipe and an armrest pipe, front leg tubes, armrest panels, an inclined push-pull pipe, a push-pull tube and the like, whenunfolded, the seat tube, the back pipe, the armrest pipe and the front leg tubes form a regular parallelogram in the same plane; one end of the inclined push-pull pipe is hinged with a front foot plate; the front foot plate is connected with the telescopic pipe and extends into a front foot pipe; another end is hignged with the seat tube, or the armrest pipe, or the upper hinged sliding sleeve onthe back pipe; the push-pull pipe is hinged with the inclined push-pull pipe and a lower sliding sleeve; the included angle between the armrest pipe and the back pipe is changed; the front leg tube,the seat tube, the inclined push-pull pipe and the push-pull tube are driven to move; so that the front upper hinge and the front lower hinge are driven for hinge, the rear upper hinge and the rear lower hinge are driven for hinge, the lower hinge sliding sleeve and the back pipe are hinged and supported, the front cross pipe and the rear cross pipe of the lower hinge sliding sleeve and the upperhinge sliding sleeve are contracted and unfolded, so that the folding chair of a square structure is folded and unfolded; and the armrest panel is sleeved on the armrest pipe, adopts a limiting chuteand can be unfolded and folded.

Description

technical field [0001] The invention relates to a furniture product, which belongs to a folding chair for outdoor travel and leisure, in particular to a folding director's chair. Background technique [0002] Among the existing folding chairs for tourism and leisure folding products, most of them are folding chairs with soft seat surfaces and soft armrests without hard tube structure. Although folding chairs with hard seat tubes and hard armrest tubes have appeared in the past ten years, When its seat tube, back tube, front leg tube, and armrest tube are arranged in a regular quadrilateral structure, folding cannot be realized. Like the traditional folding director's chair, it has a regular quadrilateral shape when viewed from the side. So far, it can only be folded into a sheet, and it cannot be folded into a column. That is to say, the traditional folding director's chair can only be folded and unfolded in two dimensions. , it is impossible to make it change in the three-...

[0002] Among the existing folding chairs for tourism and leisure folding products, most of them are folding chairs with soft seat surfaces and soft armrests without hard tube structure.

Like the traditional folding director's chair, it has a regular quadrilateral shape when viewed from the side. So far, it can only be folded into a sheet, and it cannot be folded into a column. That is to say, the traditional folding director's chair can only be folded and unfolded in two dimensions. , it is impossible to make it change in the three-dimensional direction at the same time to achieve folding and unfolding; secondly, the armrest tubes of all folding chairs are not equipped with armrest panels, because the fixed armrest panels will greatly increase the packaging volume, that is to say, the folding and folding of the chair After unfolding, the armrest panel cannot be conveniently folded and unfolded; moreover, the additional tabletops configured with traditional folding director’s chairs or ordinary folding chairs are all hard panels, which protrude beyond the chair, occupying the aisle and other spaces, affecting other personnel to pass through.
