ABSTRACT:
A bulkhead formed of nesting channels connected together with toggle arms. The channels are attached to the forward wall of a refrigerated trailer and form a barrier to protect a refrigeration unit and provide an unrestricted air passage duct for return air. A channel shaped outboard extending support member swivels on toggle arms and due to its overcenter arrangement, remains extended vertically. When the outboard member is rotated upwardly, the channels and toggles nest together decreasing the depth of the apparatus. The collapsed position is maintained by several spring retaining clips that grasp a toggle arm connecting member.
In another embodiment the channels are connected together with a solid partition which is positioned above the floor and below the air discharge opening of a refrigeration unit.
