Abstract

The utility model discloses a structure of a chair seat of a butterfly chair. The utility model is characterized in that a supporting rod is arranged on the periphery of a cloth surface of the chair base; the supporting rod can support and shape the cloth surface of the chair base. After the chair base is arranged into different shapes, the chair base is supported into a predetermined shape by the supporting rod. Thus, the chair of the utility model can have more models because of the diversity of the chair seat when the chair is used.

Description

Butterfly chair chair base structure

Technical field

The utility model is about a kind of folding seat, is meant a kind of butterfly chair chair base structure especially.

Background technology

As shown in Figure 1, butterfly structure of chair in the existing folding seat, its chair shelf structure is to cooperate eight legs to articulate in twos by eight poles to constitute, to form four chair footings and four seat support fulcrums, the seat support cloth cover back side is provided with four cover angles, just forms the folding seat that a profile is similar to butterfly after these four cover angles are placed on four seat support fulcrums.The folding seat of this structure, because its Area of bearing is big, thereby it is comfortable to be seated, but the seat support cloth cover is to rely on four seat support fulcrums to support, and seat support cloth cover material softness can't be finalized the design, so the profile form of chair is single, and can't realize shape design.At present, the user to the requirement of folding seat not only be confined to conveniently, comfortable, more need the attractive in appearance of its profile, how butterfly chair chair shelf structure being propped up and overhanging abundanter folding seat moulding is the problem that the utility model need solve.

The utility model content

Main purpose of the present utility model provides a kind of butterfly chair chair base structure, and it can make seat support have the function of mouldable.

Secondary objective of the present utility model provides a kind of butterfly chair chair base structure, and it is convenient to fold.

For achieving the above object, solution of the present utility model is: a kind of butterfly chair chair base structure, it is that periphery at the seat support cloth cover is provided with support bar.

Described seat support cloth cover periphery is provided with the accommodation space that is nested with support bar.

Described support bar is to be joined end to end by at least two sections rod members to be linked together by articulated part.

Described articulated part is to be unidirectional pivot joint.

Described support bar is the plastic flexible link of tool.

Described support bar is circle, polygon or cartoon animals shape.

After adopting such scheme, because being the periphery at its cloth cover, seat support of the present utility model is provided with support bar, this support bar has one to the seat support cloth cover and supports the function that formalizes, seat support goes out default form by they sup-port after different shapes can be set, and therefore makes chair of the present utility model because the diversity of seat support makes chair can have more moulding; In addition, because support bar is to be connected by articulated part, then seat support also can be realized the function that folds.

The specific embodiment

As shown in Figure 2, butterfly chair of the present utility model is to be made of chair frame 1 and seat support 2.

Chair frame 1 is to be articulated in twos by eight poles 11 to constitute the chair shelf structure of an expansion back like butterfly shape on eight pin joint seats 12, certainly this chair frame 1 is not confined to the structure of eight poles, as uses ten poles to cooperate ten pin joint seats can constitute one equally to be launched into pentagonal chair shelf structure.

Seat support 2 is to be a cloth cover, Si Jiaochu at its back side is provided with four cover angles 21 that can be placed on chair frame 1 strong point, key of the present utility model is: be that peripheral region at seat support 2 cloth covers is provided with accommodation space 22, one support bar 3 that cooperates seat support 2 to preset forms is to be placed in this accommodation space 22, support the effect that formalizes seat support 2 cloth covers are had one, demonstrate fully the shape of seat support, be to be example in the present embodiment with the circle, this circular support bar 3 is by unidirectional articulated part 32 be articulated (seeing shown in Figure 3) by two sections semicircular support bars, 31 head and the tail, just because of articulated part 32 is unidirectional pivot joint, be that articulated part 32 is only to the bending of the back side of seat support 2, therefore after seat support 2 launches, 1 pair of seat support 2 of chair frame is support forces upwards, the direction of its support just in time direction with articulated part 32 bendings is opposite, and support bar 32 can not subside; If as the folding chair, only need seat support 2 is folded down from chair frame 1, seat support 2 can be by the pivot joint effect of articulated part 32 folding get up (seeing shown in Figure 4).

As shown in Figure 5, be that of the present utility model another implement illustration, the support bar 3 of seat support 2 can form the seat support that seat support 2 that a pentagon then supports promptly forms a pentagon; Support bar 3 can also adopt has plastic flexible link, and the user can fold the required shape of controlling oneself according to the hobby of controlling oneself.

Just because of the setting of seat support support bar in the utility model, support bar can cooperate chair cloth to be preset to polygon or cartoon form, enriches the appearance and modeling of chair with this.
