Bookcase

Abstract

A bookcase includes a case made of wood plates or plastic plates. The case is formed with a left side plate and a right side plate, a lower side plate and a rear side plate. The lift and the right side plate respectively have a lower edge provided with a moving perforation, which forms a certain depth by making use of the thickness of the wood plate or the plastic plate of the case, respectively having an upper edge disposed with a lifting handle. Thus, a user can move the case by extending fingers into the moving perforations or lift up the case by the lifting handles and further. Two or more cases can be superposed and combined together by having the lifting handles of the lower case inserted into the moving perforations of the upper case. The bookcase of this invention is original in structure, able to be moved, lifted and superposed.
