Abstract
Abstract Two embodiments of freight bracing systems for supporting or bracing freight within a cargo area. Each system embodies belt rails that extend along opposite walls of a cargo area and which belt rails define spaced attachment means along their length. A number of bracing units are supported upon the belt rails with their freight engaging faces extending either horizontally whereby the units function as pallets or with their freight engaging faces extending vertically whereby the units function as bulkheads. Each unit is capable of acting as a pallet or a bulkhead. In one embodiment, the end fittings which support the bracing unit upon the belt rails include releasable locking means with an actuating mechanism that is adapted to be engaged by the forks of the fork lift truck regardless of the position of the unit for release of the latching means automatically upon the engagement of the forks with the release mechanism.

A combined pallet and bulkhead unit comprising frame means defining a load engaging face adapted to support cargo thereupon when positioned horizontally and adapted to engage a side of the cargo when positioned vertically to prevent shifting thereof, first and second spaced end fitting means at one side of said frame means for supporting said one side of said unit upon cooperating attachment means of a belt rail or the like, third and fourth spaced end fitting means at the other side of said frame means for supporting said other side of said unit upon cooperating attachment means of a belt rail or the like, the portion of each of said end fitting means adapted to cooperate with the belt rail attachment means being symmetric about a central axis for attachment of said end fitting means to the cooperating belt rail attachment means with said load engaging face extending either horizontally or vertically and without necessitating reorientation of said end fitting means relative to said frame means, and engagement means carried by said frame means and defining at least one pair of spaced openings for receiving the forks of a fork lift truck, each of said openings being sized and positioned to receive a respective of the forks regardless of whether said load engaging face is disposed horizontally or vertically, said openings being disposed to supportingly engage said bracing unit upon the forks when said bracing unit is in one of its positions and for continuing the support of the bracing unit upon the forks upon manipulation of said bracing unit into its other position, said openings being sized to facilitate the movement of said unit between its positions while supported upon the forks.
