Abstract
Abstract An integrally molded, one-piece, plastic shelf unit which can be mounted directly on a surface either singly, or adjacent similar units, without the need for separate mounting structures such as brackets, and which is nestable for convenient shipment and storage is disclosed. It has a flat horizontal support wall, an integral front wall which extends downwardly from the front edge of the support wall, integral sidewalls which extend downwardly from the side edges of the support wall, and an integral external mounting flange wall which extends outwardly from the rear edges of the support wall and the sidewalls to provide an unobstructed rear opening in which a similar unit may be nested.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
An integrally molded, one-piece, nestable, plastic shelf unit comprising, a flat horizontal support wall having a front edge, a rear edge longer than said front edge, and side edges extending therebetween, the distance between said side edges increasing rearwardly, an integral front wall extending downwardly from the front edge of said support wall, integral sidewalls extending downwardly from the side edges of said support wall, and an integral external mounting flange wall extending outwardly from the rear edges of said support wall and said sidewalls providing an unobstructed rear opening of greater horizontal dimension than that of said front wall, whereby said shelf unit is nestable within another unit having the same construction, for storage and shipment.
Claim 2
Dependent Claim
117 words
An integrally molded, one-piece, nestable, plastic shelf unit comprising, a flat horizontal support wall having a front edge, a rear edge longer than said front edge, and side edges extending therebetween, the distance between said side edges increasing rearwardly, an integral front wall extending downwardly from the front edge of said support wall, integral sidewalls extending downwardly from the side edges of said support wall, and an integral external mounting flange wall extending outwardly from the rear edges of said support wall and said sidewalls providing an unobstructed rear opening of greater horizontal dimension than that of said front wall, whereby said shelf unit is nestable within another unit having the same construction, for storage and shipment.
Claim 3
Dependent Claim
38 words
A shelf unit as claimed in claim 1, wherein said support wall has a rim extending upwardly from said front and side edges thereof providing with said flange wall a depressed support wall for retention of liquid thereon.
Claim 4
Dependent Claim
14 words
A shelf unit as claimed in claim 1 wherein said side edges are symmetrical.
Claim 5
Dependent Claim
41 words
A shelf unit as claimed in claim 1, wherein said sidewalls have front edges contiguous with and of the same vertical length as the side edges of said front wall, and rear edges of greater vertical length than the front edges.
Claim 6
Dependent Claim
173 words
An integrally molded, one-piece, nestable, plastic shelf unit comprising, a flat horizontal support wall having a front edge, a rear edge longer than said front edge, and side edges extending therebetween, the distance between the side edges increasing symmetrically rearwardly, said support wall having an integral upwardly extending rim around the edges thereof, an integral front wall extending vertically downwardly from the front edge of said support wall, integral sidewalls extending vertically downwardly from the side edges of said support wall, said sidewalls having front edges contiguous with and of the same vertical length as the side edges of said front wall and rear edges of greater vertical length than said front wall, and an integral planar external mounting flange wall extending vertically upwardly from the rear edge of said support wall, and outwardly from the rear edges of said sidewalls, providing an unobstructed rear opening of greater horizontal dimension than that of said front wall, whereby said shelf unit is nestable within another unit having the same construction, for storage and shipment.
Claim 7
Dependent Claim
173 words
An integrally molded, one-piece, nestable, plastic shelf unit comprising, a flat horizontal support wall having a front edge, a rear edge longer than said front edge, and side edges extending therebetween, the distance between the side edges increasing symmetrically rearwardly, said support wall having an integral upwardly extending rim around the edges thereof, an integral front wall extending vertically downwardly from the front edge of said support wall, integral sidewalls extending vertically downwardly from the side edges of said support wall, said sidewalls having front edges contiguous with and of the same vertical length as the side edges of said front wall and rear edges of greater vertical length than said front wall, and an integral planar external mounting flange wall extending vertically upwardly from the rear edge of said support wall, and outwardly from the rear edges of said sidewalls, providing an unobstructed rear opening of greater horizontal dimension than that of said front wall, whereby said shelf unit is nestable within another unit having the same construction, for storage and shipment.
