Abstract

The utility model relates to a portable foldable chair, which comprises three vertical rods. Two supporting rods whose center is hinged are connected between each two vertical rods; the lower end of each supporting rod is hinged with a fixed sleeve joint piece which is arranged on the lower end of the vertical rod, and the upper end of each bearing rod is hinged with a movable sleeve joint piece which is sheathed with the vertical rod and can move from bottom to top along the vertical rod; a triangular cushion which is made of nylon fabric is arranged above the movable sleeve joint piece by three rings; the upper end of each vertical rod is respectively provided with a lantern ring, wherein, two lantern rings are connected with a belt, and the another lantern ring is connected with the vertex angle of a triangular backrest which is made of nylon fabric, the triangular backrest intersects with the belt, and the hemline of the triangular backrest is connected with the triangular cushion. The vertical rods and the bearing rods are composite plastic pipes made of glass fiber reinforced polycarbonate.

Description

Folding camp chair

The utility model relates to a kind of lightweight, can fold and use and chair easy to carry.

Though existing folding seat has multiple shape, but it is folding that folding mode is face-back of the body formula, promptly folding back seat surface and backrest stacks or be arranged in a plane substantially, this folding mode has just reduced the size of the one-dimensional space, and the volume after folding remains bigger, and, mostly existing folding seat is to make framework by metal tube or timber, very heavy, therefore, existing folding seat remains and is not easy to carry.

It is little but also can be at the folding folding camp chair of two-dimensional space that the purpose of this utility model provides a kind of not only weight, is easy to carry very much after this chair is folding.

For achieving the above object, the structure of the folding camp chair that the utility model proposes and material therefor all are different from existing folding seat, its framework is made by high-intensity glass fiber reinforced polycarbonate composite plastic pipe, its structure is such: the pole that is hinged and connected by two central authorities between per two in three vertical rods connects and supports, total six roots of sensation pole, the hard-wired Coupling in the lower end of pole and the lower end of vertical rod is hinged and connected, the upper end of pole is hinged and connected with the movable sleeve fitting that is enclosed within the vertical rod and can move up and down, a triangle cushion is installed between three movable sleeve fittings, cushion is made by the Foldable material of softness, such as adopting nylon cloth.In the upper end of vertical rod a collar is arranged respectively, two collars wherein link to each other with the two ends of a strap respectively, the drift angle of subtriangular backrest is connected on the another one collar, and the base of triangle backrest links to each other with cushion, backrest and above-mentioned belt intersect, when being deployed into maximum rating, cushion and belt are basic horizontal, and backrest then comprises one section vertical part; Thereby the formation chair, and belt also can be made handrail usefulness.

Because the movable sleeve fitting can move up and down, thereby the angle between the pole that is hinged and connected can change, when the distance between vertical rod reduces gradually, the upper end of pole moves up, and almost stacks abreast until pole and vertical rod, from cross section, leg-of-mutton each length of side is all pursued to be tapered to and is got small size, thereby realized the folding of two-dimensional space, again because do not use very heavy metal or wood materials, so the folding seat of said structure is very portable.

Below in conjunction with embodiment and accompanying drawing the utility model is described further.

Fig. 1 is the front view that is deployed condition according to the folding camp chair that the utility model proposes;

Fig. 2 is the vertical view of folding seat shown in Figure 1;

Fig. 3 is the state diagram behind folding seat shown in Figure 1 folding.

As depicted in figs. 1 and 2, this folding camp chair comprises three vertical rod 1a, 1b and 1c, being hinged and connected pole by two central authorities between wherein per two vertical rods connects and supports, only show wherein two pole 2a and 2c among Fig. 1, the central authorities of these two poles are hinged by rivet 3a, the lower end of every pole is hinged with the fixed cover fitting (there is shown fixed cover fitting 4a and 4c) that is fixed on the vertical rod lower end, the upper end of pole is then hinged with movable sleeve fitting (there is shown movable sleeve fitting 5a and 5c), fixed cover fitting and movable sleeve fitting include the porose blade in a pipe and the pipe outside, pipe is enclosed within the vertical rod, porose blade then is used for pole hinged, the fixed cover fitting is fixed on the vertical rod lower end by screw, the movable sleeve fitting then can move up and down along vertical rod, a ring (ring 7a and 7c shown in the figure) is arranged on each angle of triangle cushion 6, this ring set is above movable sleeve fitting blade, under the deployed condition in Fig. 1, cushion 6 is level substantially, in the vertical rod upper end collar 8a is installed, 8b and 8c, between

collar

8a and 8b, be connected with a strap 9, between collar 8c and cushion 6, be provided with backrest 10, backrest 10 intersects with belt 9, backrest 10 is triangular in shape, this triangle drift angle links to each other with collar 8c, its base then is fixed on the cushion 6, under deployed condition shown in Figure 1, belt 9 is basic horizontal, and the latter half of backrest 10 then is vertical substantially.In this embodiment, vertical rod and pole are the glass fiber reinforced polycarbonate composite plastic pipe, and the Coupling and the collar are that rigid plastic of polyvinyl chloride is made, and 10 on belt 9 and backrest are nylon cloth.Fig. 3 shows the folded state of this folding seat, and at this moment, all vertical rods and pole almost stack abreast.

Claims

1, a kind of folding camp chair, it is characterized in that comprising three vertical rods, the pole that is hinged and connected by two central authorities between per two of three vertical rods connects and supports, the hard-wired fixed cover fitting in the lower end of every pole and vertical rod lower end is hinged, the upper end of pole is hinged and connected with the movable sleeve fitting that is enclosed within the vertical rod and can move up and down, a ring is arranged above movable sleeve fitting in the every vertical rod, each ring links to each other with an angle of triangle nylon cloth cushion, every vertical rod upper end one collar is arranged also, two collars wherein link to each other with an end of a belt respectively, another then links to each other with the drift angle of triangle nylon cloth backrest, the triangle backrest intersects with belt, its base links to each other with cushion, under this folding seat deployed condition, cushion and belt basic horizontal, and backrest comprises one section vertical part, all vertical rods and pole are the glass fiber reinforced polycarbonate composite plastic pipe.
