Description

Foldable chair

Technical field

The utility model relates to daily life household goods field, is specifically related to a kind of Foldable chair that can carry out various deformation.

Background technology

Mostly currently marketed folding seat is function singleness, its design concept is based on " seat " mostly, so although the chair appearance of all kinds of various kinds is different, but function is but all similar, and because will weight issue be considered, so the lighter general mobility all paying attention to it, and ignore its comfortableness and functional.Contrary, what weigh some a little has badly influenced again its mobility.

Simultaneously in view of current couchette for be seriously greater than to, so a lot of people can't buy sleeping berth, the passenger therefore buying long-distance seat ticket, taking in way and will keep sitting posture always, can not sleep on all fours, and the passenger having bought station seat is in addition unbearable especially.

Therefore need the product designing a kind of chair class, not only can carry out basic functions such as sitting or lie, also there is mobility and flexible variability, those can be helped to can't buy the passenger of sleeping berth.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, a kind of problem not only solving weight and function and comfortableness is provided, but also extend the unexistent function of folding seat in the former market of part, the Foldable chair of different occasion can be adapted to.

The utility model solves the technical scheme that its technical problem adopts:

Foldable chair, includes backrest, chair leg and cushion, it is characterized in that: described backrest, chair leg and cushion are all hinged on same main shaft, and free to rotate, form three hinge structures; The chair leg being provided with level bottom wherein said chair leg supports; Described backrest can be pivotally lowered into and the support and connection of chair leg around main shaft, forms the triangle rock-steady structure of backrest, chair leg, chair leg support three formation; Described backrest top is also hinged with turnover supporting plate.

In such scheme, described cushion is rectangular frame structure, and cushion both sides are Telescopic rod structure, and can along extending with hinged main shaft vertical direction and drawing in.

In such scheme, described backrest is also rectangular frame structure, and backrest appearance and size is greater than cushion appearance and size.

In such scheme, described supporting plate is also rectangular frame structure, and its supporting plate base is hinged on backrest top.

In such scheme, described supporting plate both sides are also Telescopic rod structure, and its both sides bearing of trend, for stretch out towards direction, supporting plate base, forms the slab construction being hinged on backrest top with middle part after extending.

The beneficial effects of the utility model are:

The utility model folding chair structure is simple, is easy to carry, not only can carries out basic functions such as sitting or lie, also have mobility and flexible variability, those can be helped to can't buy the passenger of sleeping berth, can adapt to different occasion.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is further described:

Foldable chair as shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4, includes backrest 1, chair leg 2 and cushion 3, and described backrest 1, chair leg 2 and cushion 3 are all hinged on same main shaft, and free to rotate, form three hinge structures; The chair leg being provided with level bottom wherein said chair leg 2 supports 5; Described backrest 1 can be pivotally lowered into around main shaft and support 5 with chair leg and be connected, and forms backrest 1, chair leg 2, chair leg support the triangle rock-steady structure that 5 threes are formed; Described backrest 1 top is also hinged with turnover supporting plate 4.

In the present embodiment, described cushion 3 is rectangular frame structure, and cushion 3 both sides are Telescopic rod structure, and can along extending with hinged main shaft vertical direction and drawing in.

In the present embodiment, described backrest 1 is also rectangular frame structure, and backrest 1 appearance and size is greater than cushion 3 appearance and size.

In the present embodiment, described supporting plate 4 is also rectangular frame structure, and its supporting plate 4 base is hinged on backrest 1 top.

In the present embodiment, described supporting plate 4 both sides are also Telescopic rod structure, and its both sides bearing of trend, for stretch out towards direction, supporting plate 4 base, forms the slab construction being hinged on backrest 1 top with middle part after extending.

When the utility model uses, following function can be produced by distortion:

Sit (band backrest): as shown in Fig. 1 Fig. 2 this function and folding seat there is no what difference.It is all the function of the most basic seat for meeting chair.But for meeting the requirement of its comfortableness, as shown in Figure 2 sit basis on also with backrest, so not only can meet comfortableness, more can visual surround environment space size and use, more there is flexibility.

Lie: the chair of this function also occurs in market as shown in Figure 3, as seabeach desk chair all there is the function of lying.But under comparing, the utility model embodiment more has advantage in flexibility and mobility.

Lie prone: the folding seat as shown in Figure 4 in Vehicles Collected from Market does not possess this function, not only can as simple desk in time putting this function to good use, seem especially to lie prone when tired and to sleep above.

More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
