A quick-fastening element is provided for fastening a guide rail to two adjacent horizontally extending bars arranged in a vertically superposed and parallel relationship. The quick-fastening element has a first holding portion adapted for a positively locking engagement with a first horizontally extending bar of the two adjacent horizontally extending bars, a second holding portion adapted for a positively locking engagement with a second horizontally extending bar of the two adjacent horizontally extending bars, and a connecting portion between the first and second holding portions and connecting the first and second holding portions. Each of the first and second holding portions extends from the connecting portion to one side in angled relationship to the connecting portion fastenably between the two adjacent horizontally extending bars. The connecting portion is configured for fastening the guide rail.

The modular panel 20 interlocking and reinforcing mechanism for building enclosures pertains to assembling boxes 21 without using accessories. My mechanism joins modular panels 20 by interlocking between grooves 22 and grooves 22 and rods 18 attached to panel edges, thus creating the box 21. The embodiment of my mechanism joins modular panels 20 by interlocking both grooves 22 attached by living hinges 24 on the panel edges, thus creating the box 21. The living hinges 24 allow all the grooves 22 to turn forty five degrees at the corners. Upon interlocking both grooves 22, it completes the ninety degree dihedral angle transition from one panel 20 to another for corners. Another embodiment of present invention is to assemble a box 21 in expanded sizes by interlocking modular panels 20 flat or angled without extra accessories. An additional embodiment of my mechanism includes insertion of rods 18 attached to the panel edges into grooves 22 attached to another panel to form an interlocked rod and groove 60 on box 21. One type of the interlocking groove 22 mentioned above is a rolled sheet type with a smaller span at the opening than parallel spans at main sections in the groove in a cross-sectional view. The interlocked rod and groove 60 attached to panels on living hinges 24 can also serve as posts to take loads above them for a heavy-duty box.

A bed frame includes a backrest, a bedstead and a plurality of connectors to couple the backrest with the bedstead. A connector includes first, second, third and fourth segments, in which each of the second, third, and fourth segments extends from a lower side of the first segment. A first slot is formed between the second and third segments to accommodate a bar of the backrest, and a second slot is formed between the third and fourth segments to accommodate a bar of the bedstead. When the bed frame is assembled, each connector in the plurality of connectors is fixedly coupled with the bar of the backrest, and snap-fitted on the bar of the bedstead.
