Abstract
A combined dock seal and shelter consisting of a pair of spaced side members each having a side pad with a compressible foam core and a flap member having a portion attached to the outer surface of each side pad with each of the flap members having an overhanging portion extending inwardly toward each other beyond the side pads, each of the side pads having a longitudinal axis and the flap members having a greater resistance to bending about the longitudinal axes than the resistance which the cores have to compression so that the flap members are distorted less than the side pads are compressed when the flap members are deflected by a truck, and a bellows seal construction fixedly secured between the bottoms of the overhanging portions of the flap members and a building wall to provide sealing in this area.
Claims31
A combined dock seal and shelter for mounting on opposite sides of a doorway in a building wall comprising a pair of spaced side members including substantially parallel vertical elongated side pad members having longitudinal axes and compressible flexible resilient cores, first sides on said side pad members for placement in contiguous relationship to said building wall, second sides on said side pad members on the opposite sides of said side pad members from said first sides for placement in spaced relationship to said building wall, third sides on said side pad members facing each other and extending transversely to said first and second sides, securing means for securing said side pad members to said building wall, said cores having a first resistance to compression from a normal unstressed condition, elongated flexible resilient substantially planar sheet-like side flap members having a width which includes first and second portions which are continuations of each other, means securing said first portions on said second sides of said side pad members with said second portions extending beyond said second sides toward each other for providing spaces between said second portions and said building wall, said third sides intersecting said side flap members at the junctions of said first and second portions, said side flap members having a second resistance to deflection from a normal unstressed condition in a direction about said longitudinal axes throughout sufficient portions of said first and second portions which is greater than said first resistance to compression so that when forces are applied to said second portions of said side flap members along paths which are substantially parallel to said longitudinal axes said first and second portions of said side flap members will compress said elongated pad members primarily at the junctions of said second and third sides because said elongated side pad members have said first resistance to compression which is less than said resistance to deflection of said side flap members throughout said sufficient portions of said first and second portions.
In a building construction having a door opening and side wall portions on opposite sides of said door opening, a dock shelter construction comprising a pair of spaced side members, means mounting said side members on said side wall portions, flap members having upper and lower portions, means mounting a flap member on each of said side members, overhanging flap portions of said flap members extending inwardly toward each other from said side members and spaced from said side wall portions, bellows seal means comprising hollow bellows-like members for sealing the spaces between said overhanging portions and said side wall portions, and attachment means affixing said bellows seal means between said lower portions of said overhanging flap portions and said side wall portions.
A dock shelter construction comprising a pair of spaced side members, a flap mounted on each of said side members and extending toward each other from said side members and having lower ends, and a bellows seal means mounted at said lower ends of each of said flaps for providing a seal at said lower ends, said bellows seal means being a hollow bellows-like member.
A bellows seal for attachment between a flap of a dock shelter and a building wall comprising hollow expandible and contractible accordian-pleated body means for providing a seal between said flap of said dock shelter and said building wall, first and second opposite ends on said body means, vent means in said body means for permitting air to enter said body means when it expands and for permitting air to discharge from said body means when it contracts, first attachment means on said first end for attaching said body means to said building wall, and second attachment means on said second end for attaching said body means to said flap of said dock shelter.
In combination, a dock shelter and a bellows seal, said dock shelter including flap means which are to be spaced from a building wall, an outer side on said flap means for engagement by the rear end of a truck, an inner side on said flap means for facing said building wall, and said bellows seal comprising hollow expandible and contractible accordian-pleated body means for providing a seal between said inner side of said flap means and said building wall, first and second opposite ends on said body means, vent means in said body means for permitting air to enter said body means when said body means expands and for permitting air to be discharged from said body means when it contracts, first attachment means on said first end for attaching said accordian-pleated body means to said inner side of said flap means, and second attachment means for attaching said accordian-pleated body means to said building wall.
