Abstract

The utility model relates to a portable vehicle which uses various joints to connect circular or squared pipes. A plurality of layers of expansion pipes are sleeved in some pipes, and the purpose of one vehicle with multiple functions can be realized by elaborately designing the length and the connecting matching form of each connecting pipe. The portable vehicle can be folded up when the portable vehicle is not used, and has the advantages of light weight, small size, convenient carrying and convenient storage. When the portable vehicle is used, the portable vehicle can be changed into the needed appliances, such as baggage vehicles, baby vehicles, chairs, etc., through changing the length of the expansion pipes and the connecting direction of the connecting pipes.

Description

A kind of light roadster

The utility model relates to daily necessities.

Daily being seen light roadster has baggage car, perambulator, and folding platform (stool) etc., these light roadsters generally all are foldings, volume after folding is little, is easy to carry, and is specially adapted to go on business, travels, goes into the street etc.The shortcoming of these light roadsters is that purposes is single, and some (for example perambulator) used certain hour just useless.

The purpose of this utility model is a kind of light roadster of design, and one the car that can fold, just the connection form of length by changing expansion link and pitman can produce the apparatus of various functions, as baggage car, perambulator, seat etc., realizes that a car uses more.

The utility model is achieved in that the multiple joint of design, will justify or the square tube connection with joint, cover several layers telescopic pipe in some pipe, the length of well-designed each adapting pipe and the fit form of connection also can use some to support iron sheet and connect pipe, on mobile jib and leg mobile jib rubber tire are installed.

The many usefulness of the utility model one car, the time spent is not folded up, and is in light weight, and volume is little, is easy to carry and collects, just the length that can be by changing expansion link during use and the coupling direction of pitman can produce into required apparatus, as baggage car, perambulator, seat etc.

The contrast accompanying drawing is further described with regard to the utility model below:

Fig. 1 is one of running condition figure of the present utility model, can make seat and use.
