Plastic hinged and weatherstripped metal overhead door

Claim 1

In an overhead door for a truck van, the combination comprising: a pair of relatively pivotal elongated metal door sections arranged with their adjacent longitudinal edges opposed and spaced apart, each of said sections including an outer wall flange extending along its edge and having an end face and a substantially planar inner surface, said end face of said flange of said one of said sections opposing and being spaced from said end face of said flange of the other of said sections when such flanges are substantially coplanar to provide a gap between such end faces defining a joint, and a one-piece elongated thermoplastic hinge member non-pivotally fastened to one of said sections and relatively pivotal to the other of said sections, including a rigid pin part received in a socket provided in said other of said sections and a flexible part arranged to extend across said gap and bear against such inner surfaces of said flanges when substantially coplanar thereby to seal said joint, said one-piece material being made of dual durometer thermoplastic material such that the hardness rating of said rigid pin part is greater than the hardness rating of said flexible part.
