Abstract

The utility model relates to a folding chair with a flexible seat, particularly to a chair which can be folded into a stick. A stick body is formed by folding two pairs of chair aprons and four supporting legs. Each pair of chair aprons and seat aprons are connected with two supporting legs by X-shaped hinging plates, and open dead angles are 50 to 120 DEG and 90 to 150 DEG respectively. A transverse seat rod is hinged between two pairs of corresponding seat aprons, and a transverse backrest rod is hinged between two pairs of corresponding chair aprons. A supporting central shaft arranged between center shaft sleeves of the two pairs of X-shaped hinging plates is movably connected with the X-shaped hinging plates. Handles are arranged at the ends of the chair aprons and are fixedly sheathed on seat soft cloth with high strength between the two transverse rods.

Description

Chair foldable to stick

The utility model particularly can be folded into the folding seat of walking stick about a kind of folding seat that flexible seat is arranged.

It is the interested problem of people in recent years that walking stick and seat design are integral, the utility model communique discloses " walking stick chair " respectively in the period of 87 to 89, " walking stick auto-folder stool ", utility model application cases such as " Multipurpose walking sticks ", its application number is respectively 86205495,87209632,87206047 etc., the major defect of above-mentioned prior art, when wherein spare and accessory parts being sleeved on technical scheme use together, need to become walking stick or seat with instrument disassembly and assembly again, obviously operation sequence is too numerous and diverse, and another technical scheme that assembly is hinged, form is too fat to move out of proportion when being shrunk to walking stick, and seat supporting leg foothold is opened up not open and caused seat not steady when opening.

The purpose of this utility model is will overcome all deficiencies of prior art and provide a kind of the contraction to launch convenient, the rational in infrastructure seat that can be folded into walking stick.

This seat has two secondary chair shelves and four supporting legs thereof, two secondary chair shelves and four supporting legs close up and are the cane body, and every secondary chair shelves and seat shelves are connected by the X-shaped articulated slab with two supporting legs, opening the dead angle between two supporting legs is 50～120 °, the hinged dead angle of opening is 90～150 ° between chair shelves and the seat shelves, the hinged horizontal stroke seat bar that is provided with between the two corresponding counter-base shelves, the hinged bar alongside that is provided with between the two corresponding secondary chair shelves, support axis that is provided with between two secondary X-shaped articulated slab central axle sleeves and X-shaped articulated slab flexibly connect, chair shelves end is provided with handle, at horizontal seat bar and be set with high-intensity seat soft cloth alongside between the bar.

The seat that can be folded into walking stick of said structure shape, it is very steady still to adopt four leg structures to make when seat opens.The open and flat area of seat cloth is big, chair shelves shape can be set as angle bar shape or channel shape makes when being shrunk to walking stick shape comparatively attractive in appearance, operation becomes very easy when adopting articulated structure or movable connection method to use, and the structural member amount that whole seat need be used is few in light weight, carries usefulness when being well suited for the elderly's out on tours.Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.

Fig. 1 is folded into the walking stick topology view for embodiment.

Fig. 2 is launched into the topology view of seat for embodiment.

Fig. 3 is the hinged plate view that hardens of X-shaped among the embodiment.

Fig. 4 is bar and a chair shelves articulated structure view alongside among the embodiment.
