Description

Chair rack

The utility model relates to a kind of chair frame, particularly relates to the chair frame that a kind of chair back partly can be done suitable folding.

The kind of chair is a lot of, visual use occasion, the difference of occupation mode and do different designs, and because of the different structural design of chair, space utilization when transporting or depositing making produces very big very different, the chair of leisure type as shown in Figure 1, its whole chair frame partly, roughly be between 11 liang of inboards of a pair of foot rest body, be equiped with the seat support bar 12 and chair back bar 13 that are connected with one and slightly are double L-shaped bending, stretch tight in both sides

seat support bar

12 and 13 on chair back bar and to establish strip 14, to bear the weight of human body seating on it, and wherein two chair back bars 13 are fixed the height that up extend, for the ordinary consumer desire with this type of leisure chaise longue carrying to the seashore, when use in leisure places such as leisure farm, the inconvenience on causing delivery usually and settling.

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of height that the chair back up can be extended to make the chair frame of suitable folding.

In order to realize above-mentioned goal of the invention, the utility model adopts the seat support bar and the chair frame of chair back bar that is equiped with symmetry between a pair of foot rest body inboard, and it is that both sides chair back bar is formed by two sections on last chair back bar that can corresponding socket and following chair back bar; Wherein, following chair back bar is fixedly arranged on inboard, foot rest body rear, all be installed with the guide plate that down extends and offer long guide hole and go up chair back bar inboard, make guide plate be hubbed at down inboard, chair back bar upper end with long guide hole is convexed with on the guide pillar with removing, so that chair back bar and when separating on the withdrawing up with following chair back bar, make the guide pillar of the following chair back bar of chair back bar and guide plate make the pivot pendulum, make the up curved folding of pivot of chair back bar, and reach the effect that reduces whole height for axle.

In sum, chair frame contrast prior art of the present utility model has following advantage:

A kind of chair frame that the upwardly extending height of the chair back can be done suitable folding of the present utility model when using for ordinary consumer, can be made the chair back suitable folding, the convenience on can promoting transportation and settling.

In order to realize the technical solution of the utility model, but be elaborated below by most preferred embodiment and accompanying drawing chair frame to the folding chair back of the present utility model.

Brief description of drawings:

Fig. 1 is a kind of schematic perspective view that in the past had the chair frame of fixed chair back bar.

Fig. 2 is the perspective exploded view that the chair back bar of chair frame among the utility model embodiment is the two-part combination.

Fig. 3 is the chair back bar side view before the folding not of the utility model embodiment chair frame.

Fig. 4 is the chair back bar side view after the folding of pivot pendulum up of the utility model embodiment chair frame.

Shown in Fig. 2,3, but the chair frame of the utility model embodiment folding chair back is the seat support bar 3 and chair back bar 4 that is provided with symmetry between 2 liang of inboards of a pair of foot rest body; Chair back bar 4 have can corresponding socket last chair back

bar

41 and 42 two sections on following chair back bar, and following chair back bar 42 is fixedly arranged on inboard, foot rest body 2 rear (as shown in Figure 3), its top also respectively is formed with the socket end 421 of reduced diameter, can with the corresponding socket in last chair back bar 41 lower ends; In addition, respectively there is a guide plate 412 that down extends chair back bar 41 inboards with two rivets, 411 rivet clasps on two, and offer a long guide hole 413 in guide plate 412 elongated ends, long guide hole 413 is sheathed on down on the guide pillar 422 that inboard, chair back bar 42 upper end is convexly equipped with, and guide pillar 422 outer ends form the diameter cap portion 423 big than guide hole 413 width, prevent that so as to shielding and sustain guide plate 412 it from coming off.When the socket end 421 socket one of last chair back bar 41 lower ends and following chair back bar 42, its side-looking state can supply human body make normal seating roughly as shown in Figure 3; And when chair back bar 4 has folding to need, must draw up its state of chair back bar 41(promptly as shown in Figure 2 in the elder generation), make chair back bar 41 and following chair back bar 42 separated attitudes, and the limit of taking out on it is that long guide hole 413 root edges of going up the guide plate 412 of chair back bar 41 lower ends are supported by guide pillar 422 resistances at this moment, then chair back bar 41 can guide pillar 422 be down swing of axle on the whole, can form state as shown in Figure 4, last chair back bar 41 effectively reduces the height of whole chair back bar 4 toward the curved folding of back lower place pivot; Certainly, will go up chair back bar 41 toward the curved folding of front lower place pivot (as imaginary line partly shown in), can reduce the height of whole chair back bar 4 equally, but this folding state, be unfavorable for that many chair framves do superimposed effect.
