Abstract
Abstract A decorative shelf edging strip has a generally L-shaped cross section. The strip cooperates with a metal shelf having two successive bends forming a front face and underturned lip. The front face of one of the legs of the L is treated with a decorative coating which may simulate wood grain for decorating the front face of the shelf. The second leg of the L-shaped strip terminates in a hook which engages the edge of the underturned lip of the shelf. The first and second legs of the strip form an angle slightly less than 90° and the second leg further includes a small dogleg bend. A rib extends along the length of the strip from the upper portion of the first leg. Upon installation, the hook is first engaged with the rear edge of the underturned lip of the metal shelf. Then, as the strip is pivoted into place, the rib rides along the front face of the metal shelf and opens the angles of the strip slightly as the rib moves to the crest of the bend between the top surface and front face of the metal shelf. The resiliency of the material causes the angles to close slightly after the rib passes beyond the crest, thereby providing a snap action to hold the strip in place.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
387 words
In combination, a sheet metal shelf and a shelf edging strip; said shelf having a front wall, a substantially planar top wall extending away from said front wall, and a bottom wall extending away from said front wall; said top wall forming an upper corner with said front wall and said bottom wall forming a lower corner with said front wall; said bottom wall having a distal end spaced by a predetermined distance from said front wall; said shelf edging strip comprising a molded article formed from a resiliently deflectable plastic material; said molded article including a substantially planar front portion, a substantially planar top rib extending away from said substantially planar front portion, and a bottom leg extending away from said substantially planar front portion; said front portion and said bottom leg of said shelf edging strip being juxtaposed, respectively, to said front and bottom walls of said shelf; said planar top rib of said shelf edging strip having a surface engaged with a mating surface of said planar top wall; said bottom leg of said shelf edging strip extending away from said front portion by a distance that is greater than the distance said top rib extends away from said front portion, and the distal end of said bottom leg having a hook that is hooked about said distal end of said bottom wall of the shelf; the top rib and the bottom leg of the shelf edging strip forming respective corners with the front portion of the shelf; the distance between the hook at the distal end of the bottom leg and the distal end of the top rib being less than the distance between the distal end of the bottom lip of the shelf and the corner formed between the front wall of the shelf and the top surface wall of the shelf; so that when the hook of the shelf edging strip is hooked about the distal end of the bottom lip of the shelf the planar top rib is resiliently urged into engagement with the planar top wall of the shelf; the front portion of the shelf edging strip being held in juxtaposed relation to the front wall of the shelf when the top rib of the shelf edging strip is being resiliently urged against the top surface of the shelf.
Claim 2
Dependent Claim
387 words
In combination, a sheet metal shelf and a shelf edging strip; said shelf having a front wall, a substantially planar top wall extending away from said front wall, and a bottom wall extending away from said front wall; said top wall forming an upper corner with said front wall and said bottom wall forming a lower corner with said front wall; said bottom wall having a distal end spaced by a predetermined distance from said front wall; said shelf edging strip comprising a molded article formed from a resiliently deflectable plastic material; said molded article including a substantially planar front portion, a substantially planar top rib extending away from said substantially planar front portion, and a bottom leg extending away from said substantially planar front portion; said front portion and said bottom leg of said shelf edging strip being juxtaposed, respectively, to said front and bottom walls of said shelf; said planar top rib of said shelf edging strip having a surface engaged with a mating surface of said planar top wall; said bottom leg of said shelf edging strip extending away from said front portion by a distance that is greater than the distance said top rib extends away from said front portion, and the distal end of said bottom leg having a hook that is hooked about said distal end of said bottom wall of the shelf; the top rib and the bottom leg of the shelf edging strip forming respective corners with the front portion of the shelf; the distance between the hook at the distal end of the bottom leg and the distal end of the top rib being less than the distance between the distal end of the bottom lip of the shelf and the corner formed between the front wall of the shelf and the top surface wall of the shelf; so that when the hook of the shelf edging strip is hooked about the distal end of the bottom lip of the shelf the planar top rib is resiliently urged into engagement with the planar top wall of the shelf; the front portion of the shelf edging strip being held in juxtaposed relation to the front wall of the shelf when the top rib of the shelf edging strip is being resiliently urged against the top surface of the shelf.
Claim 3
Dependent Claim
41 words
A sheet metal shelf and a shelf edging strip as set forth in claim 1, wherein said front portion of said shelf edging strip is planar and extends at a right angle to said top rib of said shelf edging strip.
Claim 4
Dependent Claim
36 words
A sheet metal shelf and a shelf edging strip as set forth in claim 2, wherein said front portion of said shelf edging strip has an integral lip extending above the plane of said top rib.
Claim 5
Dependent Claim
122 words
A sheet metal shelf and a shelf edging strip as set forth in claim 3, wherein said bottom leg of said shelf edging strip includes a first portion extending away from said front portion and a second portion extending away from said first portion to the distal end of said bottom leg; said first portion extending away from said front portion at a 90° angle and said second portion being in a state of tension in which it is urged into substantially parallel relation to said first portion when said shelf edging strip is secured to said shelf; said second portion being resiliently biased toward a condition in which said second portion extends away from said first portion at approximately 87° thereto.
