Abstract

Abstract A gravity feed display unit for mounting on a generally horizontal support surface includes a wedge shaped structure arranged for mounting on said support surface in such manner that an upper surface thereof is disposed in an inclined plane, a transverse rail having a pair of transverse vertically spaced flanges for receiving therebetween the lowermost edge of said wedge shaped structure and having a transverse bumper extending upwardly from said lowermost edge of said wedge shaped structure, and a plurality of generally channel shaped low friction elements mounted on said wedge shaped structure in side by side relation and forming a plurality of downwardly inclined guide paths for respectively receiving a plurality of rows of articles, the lowermost of which in each row is engageable with said transverse bumper whereby movement thereof is arrested.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 275 words
A gravity feed display unit for displaying articles and comprising a wedge shaped structure having a thin lowermost edge and flat upper and lower surfaces and being arranged for mounting on a generally horizontal support in such manner that the flat upper surface thereof is disposed in an inclined plane and the flat bottom surface thereof including its rear edge is generally horizontal, a generally horizontal rail transverse to said inclined plane and having a pair of generally horizontal transverse vertically spaced flanges for receiving therebetween the lowermost edge of said wedge shaped structure and having a generally horizontal transverse bumper bar extending upwardly and transversely of said lowermost edge of said wedge shaped structure, a plurality of generally channel shaped low friction elements mounted on said wedge shaped structure in side by side relation and forming a plurality of downwardly inclined guide paths for respectively receiving a plurality of rows of articles and having their lowermost ends abutting said rail, the lowermost article in each row being engageable with said transverse bumper bar whereby movement thereof is arrested, and said wedge shaped structure having a generally vertical rear surface, a tape having adhesive on opposite surfaces thereof secured to the rear surface of said wedge shaped structure so as to form a bond with a vertical panel at the rear of said wedge shaped structure, and a bracket of generally L-shaped configuration and whose vertical part is engageable with said tape in such manner that a horizontal part of said bracket underlies and engages a lower surface of said support so as to secure the rear of said wedge shaped structure against upward movement.
Claim 2
Dependent Claim 275 words
A gravity feed display unit for displaying articles and comprising a wedge shaped structure having a thin lowermost edge and flat upper and lower surfaces and being arranged for mounting on a generally horizontal support in such manner that the flat upper surface thereof is disposed in an inclined plane and the flat bottom surface thereof including its rear edge is generally horizontal, a generally horizontal rail transverse to said inclined plane and having a pair of generally horizontal transverse vertically spaced flanges for receiving therebetween the lowermost edge of said wedge shaped structure and having a generally horizontal transverse bumper bar extending upwardly and transversely of said lowermost edge of said wedge shaped structure, a plurality of generally channel shaped low friction elements mounted on said wedge shaped structure in side by side relation and forming a plurality of downwardly inclined guide paths for respectively receiving a plurality of rows of articles and having their lowermost ends abutting said rail, the lowermost article in each row being engageable with said transverse bumper bar whereby movement thereof is arrested, and said wedge shaped structure having a generally vertical rear surface, a tape having adhesive on opposite surfaces thereof secured to the rear surface of said wedge shaped structure so as to form a bond with a vertical panel at the rear of said wedge shaped structure, and a bracket of generally L-shaped configuration and whose vertical part is engageable with said tape in such manner that a horizontal part of said bracket underlies and engages a lower surface of said support so as to secure the rear of said wedge shaped structure against upward movement.
Claim 3
Dependent Claim 237 words
A gravity feed display unit for displaying articles and comprising a wedge shaped structure having a thin lowermost edge and flat upper and lower surfaces and being arranged for mounting on a generally horizontal support in such manner that the flat upper surface thereof is disposed in an inclined plane and the flat bottom surface thereof including its rear edge is generally horizontal, a generally horizontal rail transverse to said inclined plane and having a pair of generally horizontal transverse vertically spaced flanges for receiving therebetween the lowermost edge of said wedge shaped structure and having a generally horizontal transverse bumper bar extending upwardly and transversely of said lowermost edge of said wedge shaped structure, a plurality of generally channel shaped low friction elements mounted on said wedge shaped structure in side by side relation and forming a plurality of downwardly inclined guide paths for respectively receiving a plurality of rows of articles and having their lowermost ends abutting said rail, the lowermost article in each row being engageable with said transverse bumper bar whereby movement thereof is arrested, and a bracket of generally L-shaped configuration arranged with its horizontal part disposed underneath and in engagement with a lower surface of said support and with its vertical part secured to the rear surface of said wedge shaped structure by mechanical means and at a level to secure the rear of said wedge shaped structure against upward movement.
Claim 4
Dependent Claim 237 words
A gravity feed display unit for displaying articles and comprising a wedge shaped structure having a thin lowermost edge and flat upper and lower surfaces and being arranged for mounting on a generally horizontal support in such manner that the flat upper surface thereof is disposed in an inclined plane and the flat bottom surface thereof including its rear edge is generally horizontal, a generally horizontal rail transverse to said inclined plane and having a pair of generally horizontal transverse vertically spaced flanges for receiving therebetween the lowermost edge of said wedge shaped structure and having a generally horizontal transverse bumper bar extending upwardly and transversely of said lowermost edge of said wedge shaped structure, a plurality of generally channel shaped low friction elements mounted on said wedge shaped structure in side by side relation and forming a plurality of downwardly inclined guide paths for respectively receiving a plurality of rows of articles and having their lowermost ends abutting said rail, the lowermost article in each row being engageable with said transverse bumper bar whereby movement thereof is arrested, and a bracket of generally L-shaped configuration arranged with its horizontal part disposed underneath and in engagement with a lower surface of said support and with its vertical part secured to the rear surface of said wedge shaped structure by mechanical means and at a level to secure the rear of said wedge shaped structure against upward movement.
