Background technology

The existing chair of selling on the market, its structure and a great variety of models; For Convenient chair carries and collects, the chair of Xiao Shouing generally all has folding effect on the market; But the foldable structure of existing chair still has the following disadvantages: the foldable structure complexity of (1) chair, and operate loaded down with trivial details, inconvenient; (2) the chair folding poor effect of getting up still has bigger thickness, can take bigger space; Have, the chair after folding is subjected to that its folding effect is not good to be influenced, and is both heavy when people mention chair, carries because of the big inconvenience of volume again again.

The utility model content

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, and folding operation is simple and easy, quick, good, the thinner thickness of folding effect, and it is little to take up room, and light weight, the chair that is convenient for carrying.

The purpose of this utility model is to realize like this.

Faldstool, comprise seat support, the chair back and chair pin, the chair pin is divided into the forward foot in a step and the rear foot, for cross-like flexibly connects, it is characterized in that the described forward foot in a step and the rear foot are up-narrow and down-wide frame body between the forward and backward pin, rear foot top and seat support offset, middle hypomere and frame that forward foot in a step top is obliquely extended to chair back rear portion are located at the chair back two outsides, and chair back bottom is fixed with connecting lever, and the connecting lever two ends and the rear foot flexibly connect; This kind of faldstool by with forward foot in a step lengthening and extend to the middle hypomere at chair back rear portion, both can be done the back support effect, the folding effect of double as activity again cooperates the forward and backward leg structure of up-narrow and down-wide frame body again, makes chair both stable when opening, be in stacked state after the folding again, therefore, the chair thinner thickness, folding effect is good, and it is little to take up room, light weight, both convenient collection is easy to carry again, and, whole money is simple and reasonable for structure, and folding operation is simple and easy, quick.

The utility model can also adopt following technical measures to solve.

As scheme more specifically, described connecting lever comprises that fixed block and two ends thereof are turned and connects arm, and fixed block is fixed on the lower end of chair back front end face by screw, turns to connect arm and the rear foot is hinged, the chair back can be rotated, so that open or folding by connecting lever.

As better embodiment, arc transition all is arranged in the both sides, top of the forward foot in a step of described frame body and the rear foot, has both helped improving the aesthetic appearance of chair, can prevent that again frame body corner position place from damaging to human body.

As better embodiment, described chair also includes the limit guide rail sheet of approximate half frame shape, the limit guide rail sheet is installed in seat bottom, the gap that limit guide rail sheet and seat bottom have constitutes slides between spacing zone, described sliding between spacing zone passed on rear foot top, so that the rear foot is being opened or during folding, can slide in spacing interval range in its top.

Described seat bottom is fixed with installing rack near the chair back one side, and limit guide rail sheet one end links to each other with seat bottom, and the other end and installing rack join, and installing rack is connected for whole with the limit guide rail sheet.

Described installing rack two ends and connecting lever two ends are hinged.

The beneficial effects of the utility model are.

(1) faldstool of the present utility model by with forward foot in a step lengthening and extend to the middle hypomere at chair back rear portion, both can be done the back support effect, the folding effect of double as activity again cooperates the forward and backward leg structure of up-narrow and down-wide frame body again, makes chair both stable when opening, be in stacked state after the folding again, therefore, the chair thinner thickness, folding effect is good, and it is little to take up room, light weight, both convenient collection is easy to carry again, and, whole money is simple and reasonable for structure, and folding operation is simple and easy, quick.
