Description

Folding seat

Technical field

The present invention relates to tables and chairs field of structural design, be specifically related to a kind of folding seat, be applicable to the occasions such as tourism, open air, sandy beach.

Background technology

Folding seat because have light, the function such as can to stack so more and more that to be used in public arena by people, both conveniently moved, saved space again.And along with the raising gradually of people's living standard, the enhancing gradually of environmental consciousness, outdoor exercises also more and more welcomed by the people, the demand for outdoor products is also progressively improving.This has higher requirement to the outdoor leisure furniture of folding seat one class.At present, folding seat is on the market owing to adopting some cross pipe supporting constructions of unified height, four stress point perpendicular contact ground of its surrounding, it is little to there is chassis in such structure, the problems such as chair height is low, easily tumble during use, there is potential safety hazard when particularly children use, after also there is folding, volume is large simultaneously, the problems such as structural stability.

Summary of the invention

In order to overcome above-mentioned defect, the object of the present invention is to provide a kind of chassis large, Stability Analysis of Structures, and convenient folding, the folding seat of be easy to carry, transporting.

For achieving the above object, technical scheme of the present invention is:

A kind of folding seat, comprise seat-cover fabric, also comprise the long cross pipe being positioned at the left and right sides, be positioned at the short delivery breeches pipe of front and back end, stay pipe and backing tube, the bottom pipe of described long cross pipe is all provided with connector and tumbler, and the lower end of described short delivery breeches pipe is flexibly connected by the bottom of tumbler with long cross pipe, and described backing tube lower end is hinged by bottom on rear side of connector and long cross pipe;

Described backing tube is provided with slip plastic, and the rear side upper end of described long cross pipe is flexibly connected with backing tube by slip plastic with the upper end of the short delivery breeches pipe being positioned at rear end;

Described stay pipe is Collapsible structure, and it comprises inner and outer tubes, and described outer tube lower end is hinged by bottom on front side of connector and long cross pipe; Described interior pipe upper end is provided with connection plastic, and on front side of described long cross pipe, upper end is flexibly connected with stay pipe by described connection plastic with the upper end of the short delivery breeches pipe being positioned at front end; After described folding seat is opened completely, described stay pipe is in complete contraction state;

The described upper end being positioned at the short delivery breeches pipe of front end upwards extends and and is connected to form handrail by handrail fabric between backing tube.

Further improvement of the present invention is: also comprise toe board, and described toe board is connected with stay pipe outer tube by fixture.Toe board can provide more comfortable environment for use, facilitates laying of user's pin, and does not take place; And when using as children's chairs, facilitating user to take a seat, human oriented design is stronger.

Further improvement of the present invention is: described toe board is flexibly connected with a wherein toe board fixture, and forms turning structure.Do not affect the folder function of chair, and do not take place, when chair folds, convenient for collecting fasciculation, saves space, is convenient for carrying.

Further improvement of the present invention is: be provided with putting hole in the middle part of described handrail fabric, makes user in use more comfortable, chair functional stronger.

Further improvement of the present invention is: bottom described long cross pipe, all cover has footmuff, can ensure that chair not easily skids on the ground.

Its design principle based on human engineering of the chair that the present invention relates to, adopt high pin to design, after product is opened, four pin outwards strut, form larger chassis, the vertical stress point of chair is moved along on long cross pipe, center of gravity is included in the internal structure scope on chassis, make structure more stable, not easily translate into, security improves greatly, and comfortableness is also high, can be used as baby' chair and uses.

The whole chair of the present invention can faster must fold, make to shrink in all directions by multiple movable part always, pack up and fold convenient compared with other folding seat on market, and the space taken after packing up is very little, lightweight, carry transport when being convenient to outdoor activities.

Arm rest simplicity of design of the present invention, does not affect folding.

Detailed description of the invention

In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.

By reference to the accompanying drawings 1 with accompanying drawing 2, the present invention proposes a kind of folding seat, comprise seat-cover fabric, also comprise the long cross pipe being positioned at the left and right sides, be positioned at the short delivery breeches pipe 4 of front and back end, stay pipe 5 and backing tube 3, the bottom of described long cross pipe, being specially apart from ground level is that 1/6 place of long cross pipe body length is respectively equipped with connector 7 and tumbler 10, described connector 7 and tumbler 10 are all in " U " shape, described tumbler 10 is distributed in the inner side of tumbler 7, and the bottom of tumbler 10 is fixedly connected on a lateral surface of described connector 7.The lower end of described short delivery breeches pipe 4 is flexibly connected with the bottom of long cross pipe by tumbler 10, and described backing tube 3 lower end is hinged by bottom on rear side of connector 7 and long cross pipe.

See accompanying drawing 3, described backing tube 3 is provided with slip plastic 8, and the rear side upper end of described long cross pipe is flexibly connected with backing tube 3 by slip plastic 8 with the upper end of the short delivery breeches pipe 4 being positioned at rear end; Described stay pipe 5 is Collapsible structure, and it comprises inner and outer tubes, and described outer tube lower end is hinged by bottom on front side of connector 7 and long cross pipe; Described interior pipe upper end is provided with and connects plastic 9, and on front side of described long cross pipe, upper end is flexibly connected with stay pipe 5 by described connection plastic 9 with the upper end of the short delivery breeches pipe 4 being positioned at front end; After described folding seat is opened completely, described stay pipe is in complete contraction state; The described upper end being positioned at the short delivery breeches pipe 4 of front end upwards extend and and backing tube 3 between be connected to form handrail by handrail fabric, handrail is extension tube 6.
