Abstract

Resilient seal and retainer assemblies for the side edges of a swing door panel of a cargo container. Each assembly includes, in one embodiment, a resilient seal member and a relatively rigid retainer member, coextruded of polyvinyl chloride. The retainer member includes a channel part with a web and opposed flanges for receiving one of the side edges of the door panel and the retainer member also includes a base part extending from the web for supporting the resilient seal member which includes a convex, thinned-walled rim part and internal webs extending radially inwardly from the rim part to reinforce the rim part and to restore the rim part to a convex, undeflected condition when the rim part is disengaged from a sealing surface on a frame of the door panel. In an alternate embodiment, the seal member of each of the assemblies is provided with its own integral coextruded base part which may be slidably or snap-fitted into engagement with a separately formed retainer member.

Dependent claims

A seal and retainer assembly for sealing a panel edge of a swing door panel for a cargo container, said assembly comprising:

an elongated retainer member including a channel part for receiving said panel edge of said panel and for supporting said assembly on said panel and a retainer base part, said channel part including a web and opposed flanges forming a channel for receiving said panel edge, said retainer base part extending generally normal to said web and opposite said flanges, said retainer base part including a flange which extends generally normal to said retainer base part at a distal end thereof to thereby form a seal receiving channel between said web and said flange of said retainer base part;
and
an elongated seal member formed of a resilient polymer material and supported by said retainer base part, said seal member including a first rim part and a second rim part, said first rim part being generally convex in shape and having opposite ends with one of said ends being in engagement with said web and another of said ends being connected to said second rim part, said first rim part being operable to engage a frame of said cargo container to form a seal between said panel edge and said frame, said second rim part extending from said first rim part and engaging said flange of said retainer base part, said seal member further comprising at least a first interior web contiguous with said first rim part and extending toward said retainer base part and defining a plurality of interior spaces formed between said first rim part and said retainer base part to allow resilient deflection of said seal member upon engagement with said frame and to restore said seal member to an undeflected position upon disengagement from said frame.

A seal and retainer assembly for sealing a panel edge of a swing door panel for a cargo container, said assembly comprising:

an elongated retainer member including a channel part for receiving said panel edge of said panel and for supporting said assembly on said panel and a retainer base part, said channel part including a web and opposed flanges forming a channel for receiving said panel edge and said retainer base part extending generally normal to said web and opposite said flanges, said retainer base part including a flange which extends generally normal to said retainer base part at a distal end thereof to thereby form a seal receiving channel between said web and said flange of said retainer base part;
an elongated seal member formed of a resilient material and supported by said retainer base part, said seal member including a generally convex rim part having opposite ends with one of said ends being in engagement with said web and another of said ends being in engagement with said flange of said retainer base part, said rim part being operable to engage a frame of said cargo container to thereby sealingly connect said panel edge and said frame, said seal member further comprising at least a first interior web having opposite ends, one of said ends of said interior web being contiguous with said rim part and another of said ends of said interior web being connected to said retainer base part such that a plurality of interior spaces are formed between said rim part and said retainer base part to allow resilient deflection of said seal member upon engagement with said frame and to restore said seal member to an undeflected position upon disengagement from said frame.
