ABSTRACT:
A shelter or seal structure for truck docks whereat the cargo body of a truck or trailer is loaded or unloaded. The doorway in a warehouse or the like, against which the end of the cargo body is backed is provided with an exterior perimetric compressible seal structure engageable with the back end of the cargo body along the top and opposite sides. The seal structure at the sides comprises in each instance an elongated upright compressible block formed, for example, of foam rubber or the like and affixed to the outside wall adjacent the doorway. The block has a base layer of plastic sheet secured to the outer-face and an outer strip of plastic sheet fastened to the base layer at spaced locations along horizontal seams to define bulges between the seams. Upon engagement between the seal structure and the cargo body the bulges collapse accordian-fashion against the base layer and are capable of sliding in a vertical direction to accomodate vertical movement of the cargo body while backed into the dock to its loading and unloading position.
