Abstract
Abstract There is disclosed a load unitizer including upper and lower frames formed with spaced apart co-extensive corner retainers for engaging the diagonally opposed corners of polygonal-shaped cargo articles collected together in a row and coupling means is provided for coupling the opposite sides of the upper and lower frames together. Such coupling means includes a pair of connecting arms pivotally connected on their upper extremities in spaced apart relationship to one side of the upper frame and formed on their lower extremities with respective first hooks. Second hooks are mounted from one side of the lower frame in spaced apart relationship and holding means is provided for holding the first and second hooks connected together while the unitizer is transported about to transfer such cargo.

Dependent Claim
231 words
A load unitizer for holding as a unit a plurality of cargo articles formed with opposed upper and lower corners and of uniform size to be collected together in a row to dispose the respective common corners of said articles in respective straight lines, said unitizer comprising: upper and lower frames including respective pairs of spaced apart upper and lower corner retainers for projecting longitudinally of said row of articles, said upper corner retainers being shaped in cross section to nest over said opposite corners of said articles and said lower corner retainers being shaped in cross section to nest over said bottom corners of said articles; coupling means including connecting arms pivotally connected on their upper extremities in spaced apart relationship to one side of said upper frame and formed on their lower extremities with respective turned-back portions defining first hooks; second hooks mounted from said one side of said lower frame in spaced apart relationship for connecting with said respective first hooks; and holding means for holding said first and second pairs of hooks connected to one another whereby said cargo articles may be assembled in a row on said lower frame with the respective corners thereof aligned with said upper frame positioned over said articles and said first and second hooks engaged together to hold said frames together and retain said articles on a unit for transfer thereof.
Claim 3
Dependent Claim
49 words
A load unitizer as set forth in claim 1 wherein: said holding means includes U-shaped brackets formed at their bases with slots for passage of said arms, said brackets being slidable downwardly on said arms to engage the opposite legs thereof over the opposite sides of the engaged hooks.
Claim 4
Dependent Claim
36 words
A load unitizer as set forth in claim 1 that includes: side bars disposed on opposite sides of said frames and having their upper and lower marginal ends received between said corner retainers and said articles.
Claim 5
Dependent Claim
116 words
A load unitizer as set forth in claim 1 wherein: said upper frame is formed on its opposite sides with downwardly projecting longitudinally spaced apart mounting tabs formed with rectangular slots; said connecting arms are formed at their upper extremities with rectangular slots overlying said respective first-mentioned slots; and said unitizer includes lock pins including respective shafts receivable through said respective slots and formed on their one extremities with integral enlarged-in-cross section heads and on their opposite extremities with enlarged-in-cross section rectangular keys receivable in their longitudinal direction through said slots but having their long dimension longer than the width of said slots so turning thereof 90° locks said pins in place in said respective slots.
