Abstract
Abstract A one-piece plastic shelf support has a back portion with a shelf-receiving flange projecting from one side thereof and a stem projecting from the other side thereof. The back portion also includes adjacent sections that form an obtuse angle with a shoulder at the vertex of the angle and presented toward the flange. The aforesaid adjacent sections yield resiliently and flatten out as the shelf edge portion is snapped past the shoulder to seat on the flange, whereby the shelf edge portion is confined between the flange and the shoulder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
244 words
A one-piece plastic member for supporting an edge portion of a shelf on an upright and wherein the upright has at least one opening therein, comprising a back portion having a first section, a second section and a third section, said sections being contiguous and in end-to-end relationship, at least one of said first and second sections having a region for engagement with said upright, a flange projecting from one side of said back portion to provide a support for the edge portion of the shelf, said flange being substantially at the junction of said first and second sections, a stem projecting from the opposite side of said first section for engagement in said opening, said second and third sections being resilient and forming an obtuse angle, a shoulder substantially at the vertex of said obtuse angle and being presented toward said flange and being spaced therefrom to cooperate with said flange for retaining the said shelf edge portion therebetween, said second and third sections tending to flatten within elastic limits and increase said angle as the shelf edge portion is moved over said third portion and past said shoulder, whereupon the second and third sections snap back to cause the shoulder to retain said shelf edge portion, a portion of the third section remote from said shoulder having a region for engagement with said upright such that two regions are respectively above and below the shelf when the latter is on said flange.
Claim 2
Dependent Claim
244 words
A one-piece plastic member for supporting an edge portion of a shelf on an upright and wherein the upright has at least one opening therein, comprising a back portion having a first section, a second section and a third section, said sections being contiguous and in end-to-end relationship, at least one of said first and second sections having a region for engagement with said upright, a flange projecting from one side of said back portion to provide a support for the edge portion of the shelf, said flange being substantially at the junction of said first and second sections, a stem projecting from the opposite side of said first section for engagement in said opening, said second and third sections being resilient and forming an obtuse angle, a shoulder substantially at the vertex of said obtuse angle and being presented toward said flange and being spaced therefrom to cooperate with said flange for retaining the said shelf edge portion therebetween, said second and third sections tending to flatten within elastic limits and increase said angle as the shelf edge portion is moved over said third portion and past said shoulder, whereupon the second and third sections snap back to cause the shoulder to retain said shelf edge portion, a portion of the third section remote from said shoulder having a region for engagement with said upright such that two regions are respectively above and below the shelf when the latter is on said flange.
Claim 3
Dependent Claim
30 words
A one-piece plastic member according to claim 1 in which said third section tapers from said shoulder toward that end of the third section that is remote from said vertex.
Claim 4
Dependent Claim
35 words
A one-piece plastic member according to claim 1 in which said first section is planar and said vertex is offset from the plane of said first section in the direction toward which said flange projects.
Claim 5
Dependent Claim
34 words
A one-piece plastic member according to claim 3 in which said first and second sections form an obtuse angle with the vertex thereof being substantially at the junction of said first and second sections.
