Structure of collapsible rack

Abstract

A collapsible rack includes symmetric support frames composed of vertical bars and horizontal bars and top and bottom frames connected between the support frames in a movable manner. The top and bottom frames are composed of connected movable left and right boards, which have front and rear faces that define recessed channels. Spaced fitting holes are defined in the channels. Straight bars form pegs. The top and bottom frames are of movability to allow the top and bottom frames to be collapsed to a stacked flat configuration when the rack is not in use, so as to facilitate storage and transportation. When the rack is to be used, the top and bottom frames are expanded and the straight bars are set to have the pegs fit in the fitting holes defined in the left and right boards to fix the top and bottom frames in the expanded position.

AI Technical Summary

Benefits of technology

[0003]The primary objective of the present invention is to provide a structure of collapsible rack, which is expandable to receive and hold articles positioned thereon and is selectively collapsed into a stacked flat configuration to facility transportation and storage by reducing the amount of space occupied thereby.

[0004]According to the present invention, a collapsible rack comprises symmetrically arranged support frames, each of which is composed of a plurality of vertical bars and a plurality of horizontal bars, and top and bottom frames connected between the support frames in a movable manner. Each of the top and bottom frames is composed of movable left and right boards that are connected to each other. The left and right boards have front and rear faces that define recessed channels and a plurality of spaced fitting holes is defined in the channels. A plurality of straight bars is provided, each forming a plurality of pegs. The top and bottom frames are of movability to allow the top and bottom frames to be collapsed downward and upward to a stacked flat configuration when the rack is not in use, so as to facilitate storage and transportation. When the rack is to be used, the top and bottom frames are expanded and the straight bars are set to have the pegs fit in the fitting holes defined in the left and right boards to fix the top and bottom frames in the expanded position, so that the top and bottom frames can receive and support articles positioned thereon.

Problems solved by technology

The conventional rack is of a fixed structure where the frames and the shelves are fixedly mounted together, making it difficult to transport, for the transportation of the conventional rack is an effort consuming job, which often require assistance from other persons.

Further, when not in use, the conventional rack takes a great amount of space and since its size is fixed and cannot be reduced, storage of the conventional rack requires quite an amount of space.
