Abstract
Abstract A partition for separating merchandise or allocating space on perforated shelving includes an elongated planar body member and a pair of spaced feet extending laterally from one elongated edge of the body member. The integrally molded partition is made of a resilient yet stiff material such that the planar body member may be twisted about a longitudinal axis to insert first one and then the other of the feet into spaced perforations in the shelving. When the twist is released the partition is held firmly on the shelving in an upright position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A shelf partition for use with perforated shelving comprising an elongated planar body member and a pair of spaced feet extending laterally out of the plane of said planar body member in opposite directions from one elongated edge thereof, said planar body member being resilient yet stiff such that it may be twisted about a longitudinal axis to insert one and then the other of said feet into spaced perforations in said perforated shelving to secure said body member upright on said shelving when the twist is released.
Claim 2
Dependent Claim
88 words
A shelf partition for use with perforated shelving comprising an elongated planar body member and a pair of spaced feet extending laterally out of the plane of said planar body member in opposite directions from one elongated edge thereof, said planar body member being resilient yet stiff such that it may be twisted about a longitudinal axis to insert one and then the other of said feet into spaced perforations in said perforated shelving to secure said body member upright on said shelving when the twist is released.
Claim 3
Dependent Claim
43 words
The partition of claim 1 including extension members to which said feet are attached extending from said one elongated edge of said planar body member in the direction of the plane thereof to space said laterally extending feet from said one elongated edge.
Claim 4
Dependent Claim
42 words
The partition of claim 2 including a flange extending along said one elongated edge of said elongated planar member to increase the lateral stability thereof and to provide a wider base for the connection of said extension members to said planar body.
Claim 5
Dependent Claim
21 words
The partition of claim 3 wherein said flange extends laterally from each side of the elongated edge of said planar member.
Claim 6
Dependent Claim
27 words
The partition of claim 2 wherein said extension members space said feet from said elongated edge a distance slightly less than the thickness of said perforated shelving.
Claim 7
Dependent Claim
39 words
The partition of claim 5 wherein said feet extend laterally from said extension members in a direction which forms an obtuse angle with the direction in which the extension members extend from the elongated edge of the planar member.
Claim 8
Dependent Claim
15 words
The partition of claim 6 wherein said obtuse angle is between 90 and 95 degrees.
Claim 9
Dependent Claim
52 words
The partition of claim 1 including a stabilizer extending in the direction of the plane of said elongated planar body member from said one elongated edge intermediate said spaced feet, for insertion in a perforation in the shelving to provide lateral stability for the center of said resilient, elongated, planar body member.
Claim 10
Dependent Claim
49 words
The partition of claim 1 wherein each of said laterally extending feet has a face transverse to and directed away from the planar body member and wherein the edges of said face are bevelled to facilitate insertion into and removal of said feet from diamond shaped perforations in shelving.
