Description

Multifunction seat
Technical field
The utility model relates to a kind of multifunction seat, is a kind of integrate chair, wheelchair, desk, shopping cart, little pulling a cart and the multifunction seat of bed specifically.
Background technology
Existing functions of seat is simple, thereby can only simply fold to draw in, reduces floor space, and function is few, can only meet indoor routine use, function singleness.
For this reason, occurred some multifunction seats in prior art, such as Chinese utility model patent, the patent No. is " zl03244471.0 ", and name is called " multifunction chair ".Its summary and technical characterictic are: multifunction chair is both can work as chair to use; Open and also can work as single bed use; A plank is installed on two handrails, just can be sitting in above chair and have had a meal, very convenient, as to be well suited for the patient of hospital and the patient that accompanies and attends to librarian use.The structure of this multifunction chair be take iron shelf as main, although be divided into several parts, every part has axle to connect, and can realize combination and open, and it is to be combined into one with iron shelf, such structure very solid firmly, plank is arranged on iron shelf.While opening, every part is set level, and iron shelf, handrail are exactly the support of bed board, and several planks are opened successively, are exactly single bed.During withdrawal, several planks are turned back, plug steady pin, just become a chair.Iron shelf is the support of bed, is also the body supports of chair, just, after opening, just can realize different use functions.The axle of every part and plank in conjunction with very ingenious, after chair is opened, can keep the appearance on a plane, can not make because of the existence of axle the plate face can not be smooth; While closing, can not make the plate face because axle former thereby can not close yet.The sitting face plank of chair is two-layer, when being seat, and two-layer being combined into together; When as bed, this two-layer plank is opened, and be all the panel of bed, then backrest put down to (backrest also can be made folding), be exactly a single bed. 
The multifunction seat that this patented technology provides has two kinds of functions, to a certain degree solving the single problem of functions of seat, but convenient not when it uses, also need plank is carried out to dismounting, and its function or fewer, can't meet the application of multiple situation in daily life.
The utility model content
