摘要
PURPOSE: A variable cart is provided to improve work efficiency by varying the size of the cart depending on the volume and the weight of freight in the state a sub bar is connected slidingly to a main bar. CONSTITUTION: Main bars(120) are located in each corner of a body(110) and penetrated through slide slots therein. The exposed length of sub bars(130) outside the main bars are adjusted by combining to slide through both sides of the sliding slots of the main bars. Connection blocks(140) finish the shape of the body by locating the connection blocks to each apex of the body and combining the ends of the sub bars respectively. Handle portions are formed by vertically connecting the sub bars to be combined with the main bars with the connection blocks through hinges(152) to be rotatable. Then, the main bars and the sub bars, whose lengths are possible to be adjusted horizontally, are connected each other. Thereby, the handle portions(150) to be varied the size by interlocking with the body is formed. Therefore, the size of a cart(100) is varied appropriately.
