Abstract

A display shelf includes at least two side panels each panel formed with a plurality of gripping plates on the side panel, and a plurality of horizontal planks each plank formed with a plurality of side lugs each lug interlockably snapped on each gripping plate formed on the side panel so that the horizontal planks can be easily mounted on the side panels without requiring any fixing element or tool for a convenient assembly or dismantling work of the shelf.

Claims

1. A detachable display shelf comprising:

a plurality of side panels assembled with a plurality of horizontal planks, each said horizontal plank horizontally secured between a right and a left side panel;

each said side panel including a supporting clip formed on a lower portion of said side panel, a securing crimp formed on an upper portion of said side panel pivotally and releasably engaged in series with a supporting clip of another side panel, and at least two gripping plates integrally formed on said side panel; and

each said horizontal plank including at least two side lugs formed on a left side and a right side of said plank each said side lug releasably interlocked with each said gripping plate formed on said side panel;

each said supporting clip including a plurality of first leaf portions respectively arcuately protruding inwardly from a lower portion of the side panel, and a plurality of second leaf portions respectively arcuately protruding outwardly from the lower portion of the side panel, each first leaf portion being adjacent to each second leaf portion to form an arcuate clip when projectively viewed from a side view of the side panel;

each said gripping plate having a longitudinal section generally L-shaped including;

a base portion protruding inwardly from the side panel for integrally connecting the gripping plate generally perpendicular to the base portion and parallel to the side panel, a spring plate resiliently secured to the gripping plate having a convex portion protruding outwardly from the gripping plate, and an upper stopper formed on the side panel above the gripping plate, said gripping plate directly punched from the side panel to form a gripping-plate opening in the side panel, and the spring plate directly punched from the gripping plate to form a central slot in the gripping plate, and the upper stopper directly punched from the side panel to form a stopper notch in the gripping plate when punching the side panel to form the gripping plate so as to secure said upper stopper to an upper edge of the gripping plate opening and to secure the base portion of the gripping plate to a lower edge of the gripping plate opening;

each said side lug of said horizontal plank including a horizontal extension protruding sidewardly outwardly from the horizontal plank and a pendent lip secured with the horizontal extension formed with an engaging slot in the pendent lip releasably engaged with the convex portion formed on the gripping plate of the side panel, said pendent lip generally perpendicular to the horizontal extension capable of being bent obliquely from said horizontal extension.

2. A shelf according to claim 1, wherein each said horizontal extension of each said side lug includes a horizontal spring plate directly punched in said horizontal extension having a concave portion recessed downwardly on said horizontal spring plate to be releasably engaged with said stopper notch formed in each said gripping plate.
