## Abstract

A shelving unit made of vertical end panels, horizontal shelves, cornice boards and toekicks secured together in a rigid and accurate assembly of parts. The shelf at the midpoint in the height of the end panels is connected to the end panels by shelf support locking pins which restrict the end panels from flexing in or out. Locking pin brackets have locking pins to pull the cornice and toekick tight with respect to the end panels, providing a strong and accurate connection between the parts.

## Claims

### Claim 1

A shelving unit comprising laterally spaced, upright end panels, shelving extending between said end panels comprising an elongated shelf having opposite ends, and means for connecting said ends of said shelf to said respective end panels, said connecting means comprising a first pair of spaced apart shelf locking pins each having a threaded end portion threadedly engaged and anchored in one of said end panels and a shelf-supporting end portion projecting from said one end panel in supporting engagement with one end portion of said shelf, a second pair of spaced apart shelf locking pins each having a threaded end portion threadedly engaged and anchored in the other of said end panels and a shelf-supporting end portion projecting from said other end panel toward said one end panel in supporting engagement with the other end portion of said shelf, the opposite end portions of said shelf having grooves in the underside thereof receiving said shelf-supporting end portions of said respective locking pins, said shelf-supporting end portions of said locking pins each having a transverse pin projecting radially from diametrically opposite sides thereof providing a handle to facilitate threading the same into said end panels, and said end portions of said shelf having sockets receiving said respective transverse pins to prevent said locking pins from pulling away from said shelf.

### Claim 2

A shelving unit comprising laterally spaced upright first and second end panels, an elongated, horizontal panel extending between said end panels and having first and second ends, first means securing said first end of said horizontal panel to said first end panel and second means securing said second end of said horizontal panel to said second end panel, said first securing means comprising a first pair of spaced apart L-shaped brackets, said second securing means comprising a second pair of spaced apart L-shaped brackets, each bracket having first and second legs, first means connecting said first leg of each said bracket to said horizontal panel including spaced apart pins rigidly secured to said first leg and each having a head projecting therefrom, sockets in said horizontal panel receiving said pin heads, fasteners clamping said first leg of each bracket to said horizontal panel, said second leg of each bracket having an edge provided with spaced apart notches, and fasteners slidably received in said notches and clamping said second leg of each bracket of said first and second pair of brackets to said first and second end panels, respectively.
