Abstract
Abstract A gravity feed shelf includes a plurality of chutes mounted on a rectangular frame having front and rear cross supports interconnected at their ends with a pair of side supports, at least one corner junction between adjacent ends of the rear cross support and the side supports being formed by a slide connection to accommodate sidewise motion of the side supports relative to the rear cross support so that variations in the horizontal spacing between vertical support posts on which the shelf is mounted may be accommodated since the interconnection between these support posts and the shelf is via the rear ends of the side supports.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
A display shelf for mounting on a pair of vertical spaced apart upright posts the spacing between which may vary somewhat, the shelf comprising a frame having front and back cross supports and a pair of side supports interconnected at their ends with the ends of said cross supports to form a rectangular frame and interconnected at their back ends respectively with said upright posts, an inwardly projecting support panel having a transverse slot and formed on at least one of said side supports adjacent the back end thereof, said back cross support being of stepped configuration and including a first transverse strip disposed in a vertical plane and extending between said side supports, and a downwardly projecting tab formed on the lower edge of said first transverse strip at at least one end thereof.
Claim 2
Dependent Claim
135 words
A display shelf for mounting on a pair of vertical spaced apart upright posts the spacing between which may vary somewhat, the shelf comprising a frame having front and back cross supports and a pair of side supports interconnected at their ends with the ends of said cross supports to form a rectangular frame and interconnected at their back ends respectively with said upright posts, an inwardly projecting support panel having a transverse slot and formed on at least one of said side supports adjacent the back end thereof, said back cross support being of stepped configuration and including a first transverse strip disposed in a vertical plane and extending between said side supports, and a downwardly projecting tab formed on the lower edge of said first transverse strip at at least one end thereof.
Claim 3
Dependent Claim
35 words
A display shelf according to claim 1 wherein a second transverse strip is disposed in an imaginary horizontal plane and having its rear edge integrally formed with the lower edge of said first transverse strip.
Claim 4
Dependent Claim
28 words
A display shelf according to claim 2 wherein said downwardly projecting tabs are struck from the rear corner of at least one end of said second transverse strip.
Claim 5
Dependent Claim
42 words
A display shelf according to claim 1 wherein the lower end of said downwardly projecting tab is bent out of the plane of the upper end thereof thereby to secure said back cross support against upward movement relative to said side supports.
Claim 6
Dependent Claim
31 words
A display shelf according to claim 1 wherein said downwardly projecting tab includes a lateral projection at the lower end thereof and engageable with the lower surface of said support panel.
Claim 7
Dependent Claim
87 words
A display shelf according to claim 2 wherein a third transverse strip is disposed in an imaginary vertical plane and having its upper edge integrally formed with the front edge of said second transverse strip and wherein a pair of securing tabs are struck from said third transverse strip adjacent the ends thereof respectively and arranged with parts thereof in engagement with the lower surface of said support panel so as to aid in preventing upward movement of said back cross support relative to said side supports.
Claim 8
Dependent Claim
117 words
In a display shelf, a junction between a side support and a cross support comprising a support panel projecting inwardly from said side support and supported thereby, a transverse slot formed in said support panel, a tab mounted on and projecting downwardly from said cross support and disposed within said transverse slot, the length of said transverse slot being substantially greater than the corresponding dimension of said tab whereby sidewise movement of said side support relative to said cross support is accommodated, and a securing tab mounted on said cross support and in engagement with the lower surface of said support panel to aid in preventing upward movement of said cross support relative to said side support.
Claim 9
Dependent Claim
117 words
In a display shelf, a junction between a side support and a cross support comprising a support panel projecting inwardly from said side support and supported thereby, a transverse slot formed in said support panel, a tab mounted on and projecting downwardly from said cross support and disposed within said transverse slot, the length of said transverse slot being substantially greater than the corresponding dimension of said tab whereby sidewise movement of said side support relative to said cross support is accommodated, and a securing tab mounted on said cross support and in engagement with the lower surface of said support panel to aid in preventing upward movement of said cross support relative to said side support.
