Description

Fast ussembled or disassembled chair

The utility model relates to a kind of seat collapsible, dismounting that is in harmonious proportion.

Existing mass-produced means of transport (vehicle, boats and ships, aircraft) generally becomes fixed with passenger seat design, promptly use bolted on the floor, can not arbitrarily dismantle and fold, the known passenger seat that can conveniently fold is with backrest and seat cushion, adopts the hinge joint device between part chair pin and floor.HIACE(Hai Aisi as Japanese Toyota) board, LITEACE(Lai Teaisi) board tool car, minibus etc.But the seat that is erected at after folding in the compartment often hinders the goods that load volume is big and quantity is many.Since seat can not be quickly and easily demolition from the car, whole spaces in compartment are not fully utilized during cargo transport.In addition, owing to have only the chair pin of seat one side to be fixed on the floor, in case when having an accident, the security of this seat is not best.Passenger seat on american lockheed L-100-30 strong man aircraft can advance by the pulley rail on the cargo hold pallet and to pull out, and directly is screwed on the cargo deck in the time of fixedly.This seat needs could advance installation on the special cargo deck of pulley rail being equipped with pulling out.The backrest of this seat and seat cushion can not decompose and fold fast in addition, and the people that muscle power is little is difficult for alone seat being loaded and unloaded.

The purpose of this utility model be to provide a kind of simple in structure, safe and reliable, do not need any instrument just can roll over dress fast, folding and can regulate the seat of backrest inclination angle.

The purpose of this utility model realizes with the following methods.Seat is made up of chair pin, seat cushion, backrest.Between chair pin and the seat cushion, form folding being connected of removable energy by toggle formula retaining mechanism between chair pin and the floor.This structure is convenient to the fixing and dismounting on chair pin and floor, also is convenient to chair pin and seat cushion are folded.Can fold, disassemble for making between seat cushion and the backrest, combining between seat cushion and the backrest adopted the structure that tangles.Be connected with on cushion on fixed head, the backrest and be connected with fanning strip.Erection column plug assembly and elasticity are pulled on fixed head, and on the fanning strip with plunger assembly and the elasticity locating hole that the corresponding section has the camber line to distribute of pulling.Pellet shot from a slingshot and the stranded formation seat cushion of the locating hole on the fanning strip and the structure that tangles of backrest of pulling by the plunger and the elasticity of fixed head upper plug assembly.The utility model will be further described below in conjunction with accompanying drawing.
