Backplate for shelf rack

Abstract

A backplate is directly hooked at two outmost ends to two opposite inner vertical metal bars on two rear posts of a shelf rack, so that things may be safely positioned on the rack against the backplate. The backplate includes a long and narrow transverse plate, a fixed mounting bracket fixedly connected to each lateral end of the transverse plate, and a movable mounting bracket pivotally and sideward movably connected to the fixed mounting bracket. The movable mounting bracket has a hooking recess provided at an outer end for engaging with one of the two opposite inner vertical metal bars, and a second elastic retaining head forward protruded from a middle portion for tightly pressing against an inner side of a rearward protruded first elastic retaining head formed at an outer end of the fixing mounting bracket to thereby fasten the fixed and the movable mounting brackets to one another.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a backplate for shelf rack, and more particularly, to a backplate for mounting to a rear side of a shelf rack to increase the structural strength of the shelf rack and allow things to be safely positioned on the rack against the backplate.BACKGROUND OF THE INVENTION[0002]Various storing devices are provided in houses, offices, and all kinds of working places for holding and / or storing different things. The storing devices may be generally divided into two types, namely, fixed storing devices that are not easily disassembled, and sectional storing devices that can be easily assembled and disassembled. The sectional storing devices have the advantages of easy to store and transport, reducing transportation cost, and increasing market competition ability.[0003]The sectional storing devices may be further divided into two groups, a first one of which must be assembled and disassembled using any tool, while the second one is no...

AI Technical Summary

Benefits of technology

"The present invention provides a backplate for mounting to a rear side of a shelf rack by directly hooking two outmost ends of the backplate to two opposite inner vertical metal bars on two rear posts of the shelf rack, so that things may be positioned on shelves of the rack against the backplate. The backplate functions to tightly connect two side supports of the shelf rack to each other, so as to increase the structural strength of the shelf rack. The backplate includes a long and narrow transverse plate, a fixed mounting bracket fixedly connected to each lateral end of the transverse plate, and a movable mounting bracket pivotally and sideward movably connected to the fixed mounting bracket. The movable mounting bracket has a hooking recess provided at an outer end for engaging with one of the two opposite inner vertical metal bars on the rear posts of the shelf rack, and a second elastic retaining head forward protruded from a middle portion for tightly contacting with a rearward protruded first elastic retaining head formed at an outer end of the fixed mounting bracket to thereby fasten the fixed and the movable mounting brackets to one another. The transverse plate may be a flat board or a metal grid welded from a plurality intersected metal bars."

Problems solved by technology

However, even with the intersected metal bars provided at the rear side, the shelf rack 1 has poor structural strength and tends to sway, and is therefore not suitable to have a large size or hold heavy things.
