Abstract

Disclosed is a flap seat structure including six braces and two verts, the middle portions and the lower portions of the six braces are pin joint and form three supporting feet; the lower portions of the two verts are pin joint actively separately at the lower portion of two braces, one of which forms a supporting foot, while the upper portions of the two verts are pin joint and the each vert provides a positioning seat; two of the six braces are pin joint by pin part, the upper portions of the other group of braces are pin joint on the two verts by sliding carriage actively. When unfolding the upper portions of the two braces slide downward along the two verts and form two catch-points, which forms the chair back without prolonging the length of the braces, the length of the whole chair folded is shortened relative to the convention product structure, which is convenient to transport and store; meanwhile setup of the two verts improves supporting strength of the whole chair.

Description

A kind of folding seat shelf structure

Technical field

The utility model is about a kind of leisure goods, is meant a kind of folding seat shelf structure especially.

Background technology

Leisure goods is day by day abundant at present, and structure is different, and form is changeable.Particularly the foldable chair structure is constantly brought forth new ideas especially.Cooperate a kind of foldable chair frame shown in Figure 1, it is at least by the support bar 1 ' of six roots of sensation even-multiple, its two ends and middle part are articulated in twos, formation one respectively has the chair frame of three strong points up and down, wherein Xia Fang three strong points 4 ' are as the chair pin, and three strong points 5 ' of top cooperate chair cloth to form seat.For making its shape that forms seat, it is long than other support bar 1 ' wherein to have at least two support bars 2 ' to be provided with, and can form a chair back after then being nested with chair cloth, folding seat good looking appearance of forming of structure like this, and it is relatively little to fold volume.But owing to cooperate the formation of the chair back, wherein have the length of at least two support bars 2 ' to be provided with longlyer, cooperates shown in Figure 2ly, thereby after folding, the length of whole chair frame is long, is not easy to transportation and collects.

The utility model content

The purpose of this utility model is to provide a kind of can shorten length, so that transportation and the folding seat shelf structure of collecting.

For achieving the above object, solution of the present utility model is: a kind of folding seat shelf structure, constitute by six roots of sensation support bar and two montants, and wherein the middle part of six roots of sensation support bar and lower end are articulated in twos and form three feets; The lower end of two montants is movable respectively to be articulated in the wherein bottom of two support bars of a formation feet, and the upper end of these two montants is articulated by articulated part, is respectively equipped with a positioning seat simultaneously on its shaft; Above-mentioned six roots of sensation support bar wherein has the upper end of two groups of support bars to articulate two seat support strong points of formation in twos, and upper end of another group support bar is articulated on the shaft of two montants by the slide activity respectively.

Described six roots of sensation support bar is isometric, and the length of two montants is smaller or equal to the length of six roots of sensation support bar.

The articulated section of described each support bar end is to be articulated by articulated part.

The lower end of described two montants is to be articulated on the support bar by movable pin joint seat.

After adopting such scheme, because the utility model is under the situation that does not change original chair frame expansion shape, two montants have been added, the upper end activity of two support bars wherein is articulated on this montant, when launching the chair frame, the upper end of these two support bars can move down in its location, positioning seat place along two montants and form two strong points, cooperate two groups of two strong points formation seat support strong points that support bar forms in addition simultaneously, the then chair back two montants formation thus, the length of support bar of need not to extend can form the chair back, then commonly use the product structure relatively, can shorten the length after whole chair frame folds, so that transportation and collection; Simultaneously two montants is provided with the support strength that can improve whole chair frame.

The specific embodiment

As shown in Figure 3, folding seat frame of the present utility model is to be made of the isometric support bar 1 of the six roots of sensation and the two length montant 2 smaller or equal to support bar 1 length.

Wherein the middle part of this six roots of sensation support bar 1 and lower end are articulated in twos, its place, end is to be articulated by " L " type articulated part 3, certainly articulate the middle part and also can adopt the pin joint seat that increases pivot joint intensity to articulate (not shown), form three feets 4 thus; The lower end of two montants 2 is articulated in respectively on the movable pin joint seat 7, and this activity pin joint seat 7 is that activity is nested with the bottom of two support bars 1 of a formation feet 4 therein, and the upper end of these two montants 2 is articulated by " L " type articulated part 3; The place is installed with a positioning seat 21 respectively at the nearly medium position of the shaft of two montants 2; Above-mentioned six roots of sensation support bar 1 wherein has the upper end of two groups of support bars to articulate two seat support strong points 5 of formation in twos by " L " type articulated part 3, and upper end of another group support bar 1 is articulated on the shaft of two montants 2 by slide 6 activities respectively.

The folding seat frame of forming by above-mentioned each rod member, under the situation that does not change original chair frame expansion shape, two montants 2 have been added, when launching the chair frame, wherein the upper end of two support bars 2 can move down along the shaft of two montants 2, forms two strong points in its location, positioning seat 21 places, cooperates two strong points of two groups of support bar 1 formation in addition to form the seat support strong point 5 simultaneously, then the chair back thus two montants 2 form, the length of the support bar 1 that need not to extend can form the chair back; Simultaneously two montants 2 is provided with the support strength that can improve whole chair frame.

Cooperate shown in Fig. 4,5, when folding seat frame of the present utility model during in folding, wherein the upper end of two support bars 2 can be along moving on the shaft of two montants 2, each rod member is drawn close to concentrating to fold, because the length of six roots of sensation support bar 1 is isometric, and the length of two montants 2 is smaller or equal to the length of support bar 1, thereby the chair frame after folding, its entire length is commonly used the product structure relatively and is shortened to some extent, with convenient transportation and collection.
