Cargo retainer

Abstract

A cargo retainer, having a floor contacting member provided with an upwardly facing load bearing surface and an upright member secured adjacent to the rear end of the floor contacting member, is provided with a floor piercing element. The floor piercing element is movably mounted adjacent to the juncture between the floor contacting member and the upright member and is movable relative to the cargo retainer between a position of relatively shallow floor piercing engagement and a position of substantially deeper floor piercing engagement. A member projects from the cargo retainer adjacent to the juncture between the floor contacting member and the upright member in planar alignment with the floor piercing element and serves to drive the floor piercing element from a shallow engagement position to a deeper engagement position with rearward movement of the cargo retainer and thereby limit such movement in service. Means are further provided on the cargo retainer for engagement with the floor piercing element to effect removal of the element with forward movement of the cargo retainer in service. After forward movement of the cargo retainer in service, the floor piercing element is driven to reestablish a piercing engagement with the floor.
