Abstract
Abstract There is disclosed herein a rack system for use in a warehouse to store pallets loaded with goods. The system includes a plurality of racks which are separated by aisles. Each rack includes a plurality of vertical frames which are spaced apart so as to define storage rows. Each frame includes a plurality of vertical posts and horizontal pallet-rails. The pallet-rails are mounted to the posts so as to extend forwardly beyond the front posts. Thus when the rack is loaded, the front post is "buried" between rows of loaded pallets for protection against fork truck collision. Furthermore, with this positioning of the front post, the entrance or opening to the row is greater than with prior art constructions. The greater opening permits a forklift operator to more easily maneuver loads into the row or permits a reduction in the width of the aisle between racks. A protector arm assembly is provided for mounting to the front post beneath the extended pallet-rail and extending forwardly of the post for preventing injuries to personnel and loads resulting from striking the end of the rail and for providing additional support for the rail.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
A rack for use in storing loaded pallets which includes a plurality of vertical rack frames which are spaced apart so as to define a pallet-storage row between adjacent rack frames, each of said rack frames including a plurality of vertical posts, brace means interconnecting said posts, pallet-rail support means mounted to said posts, and a plurality of horizontal pallet-receiving rails supported by and mounted on said support means, said rails being constructed to receive and support loaded pallets wherein the improvement comprises: said rack frames having a front post positioned rearwardly of the front end of said pallet-rail so that a portion of said pallet-rail extends forwardly of the front post with the distance between the front post and forward end of said pallet rail being effective to permit stacking of loaded pallets on either side of said post and to extend forwardly of said front post and so as to protect said front post, and to provide a rack having the capability of providing greater turn-in clearance into a pallet row, and in combination therewith, protector arm assembly means for mounting on the front post beneath and adjacent said forwardly-extending pallet-rail, said protector arm assembly means extending forwardly of said rail for providing protection and minimizing injuries due to the forwardly-extending portion of said pallet-rail.
Claim 2
Dependent Claim
