Abstract
Abstract A storage rack structure is disclosed of the gravity feed type having inclined storage racks carried between front and rear vertical standards on which a pallet carrying cases and the like is loaded from the rear for gravity feed to the front wherein the flow rails are hung within a channel of a front facing rail having a back web providing an abutment for stopping the pallet and include a raised abutment at the rear end thereof providing a fulcrum about which the pallet initially impacts and pivots for loading onto the flow rail.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
In a storage rack structure of the type having laterally spaced front vertical standards, laterally spaced rear vertical standards longitudinally spaced from said front standards, a horizontal front facing rail member extending between said front standards, a horizontal rear rail member extending between said rear standards, and flow rail means extending between said front and rear rail members over which a pallet of articles move for loading on said storage rack structure, the improvement comprising: said front facing rail member including a channel having a front facing web, a shortened back web spaced from said facing web, a bridging flange integrally connecting an upper portion of said facing and back webs, and a rearwardly extending flange integral with a lower portion of said back web; said flow rail means including a plurality of spaced flow rails having a plurality of rollers, each said flow rail having a front end portion received within said channel of said front facing rail member adjacently underlying said rearwardly extending flange; and means for attaching each said flow rail to said front facing rail member flush against the underneath of said rearwardly extending flange in a suspended configuration.
Claim 2
Dependent Claim
193 words
In a storage rack structure of the type having laterally spaced front vertical standards, laterally spaced rear vertical standards longitudinally spaced from said front standards, a horizontal front facing rail member extending between said front standards, a horizontal rear rail member extending between said rear standards, and flow rail means extending between said front and rear rail members over which a pallet of articles move for loading on said storage rack structure, the improvement comprising: said front facing rail member including a channel having a front facing web, a shortened back web spaced from said facing web, a bridging flange integrally connecting an upper portion of said facing and back webs, and a rearwardly extending flange integral with a lower portion of said back web; said flow rail means including a plurality of spaced flow rails having a plurality of rollers, each said flow rail having a front end portion received within said channel of said front facing rail member adjacently underlying said rearwardly extending flange; and means for attaching each said flow rail to said front facing rail member flush against the underneath of said rearwardly extending flange in a suspended configuration.
Claim 3
Dependent Claim
44 words
The structure of claim 1 including raised abutment means disposed adjacent the rear end of each said flow rail extending above said rollers providing a fulcrum over which said pallet of articles may pivot to initially impact on a plurality of said rollers simultaneously.
Claim 4
Dependent Claim
28 words
The structure of claim 1 wherein said channel of said front facing rail includes a rearwardly extending flange integral with a lower portion of said front facing web.
Claim 5
Dependent Claim
33 words
The structure of claim 1 wherein said back web of said front facing rail defines an abutment for stopping the forward movement of a pallet carrying articles for storage on said rack structure.
Claim 6
Dependent Claim
206 words
In a storage rack structure of the type having laterally spaced front vertical standards, laterally spaced rear vertical standards longitudinally spaced from said front standards, a horizontal front facing rail member extending between said front standards, a horizontal rear rail member extending between said rear standards, and flow rail means extending between said front and rear rail members over which a pallet of articles move for loading on said storage rack structure, the improvement comprising: said front facing rail member including a channel having a front facing web, a shortened back web spaced from said facing web, a bridging flange integrally connecting an upper portion of said facing and back webs, and a rearwardly extending flange integral with a lower portion of said back web; said flow rail means including a plurality of spaced flow rails having a plurality of rollers, each said flow rail having a front end portion received within said channel of said front facing rail member adjacently underlying said rearwardly extending flange; means for attaching said flow rails to said front facing rail member; and a pair of spaced hat section rails carried intermediate a pair of next adjacent flow rails having outwardly extending flanges supportably carrying a wire mesh floor therebetween.
Claim 7
Dependent Claim
206 words
In a storage rack structure of the type having laterally spaced front vertical standards, laterally spaced rear vertical standards longitudinally spaced from said front standards, a horizontal front facing rail member extending between said front standards, a horizontal rear rail member extending between said rear standards, and flow rail means extending between said front and rear rail members over which a pallet of articles move for loading on said storage rack structure, the improvement comprising: said front facing rail member including a channel having a front facing web, a shortened back web spaced from said facing web, a bridging flange integrally connecting an upper portion of said facing and back webs, and a rearwardly extending flange integral with a lower portion of said back web; said flow rail means including a plurality of spaced flow rails having a plurality of rollers, each said flow rail having a front end portion received within said channel of said front facing rail member adjacently underlying said rearwardly extending flange; means for attaching said flow rails to said front facing rail member; and a pair of spaced hat section rails carried intermediate a pair of next adjacent flow rails having outwardly extending flanges supportably carrying a wire mesh floor therebetween.
