Abstract
An overhanging barrier fin weatherstrip and method having a backing strip, and one surface of a sealing body affixed thereto with the opposite surface free. The backing strip and sealing body form a sealing assembly. An inverted shallow V-shaped barrier fin is provided having first and second web portions joined together along a common fold line. The barrier fin is arranged with an edge surface of the first web portion secured to the sealing assembly, and the first web portion extending vertically with the fold line substantially at the level of the opposite free surface of the sealing body. The second web portion extends outwardly from the fold line overhanging the opposite free surface of the sealing body.
Claims8
An overhanging barrier fin weatherstrip comprising:
- a longitudinally extending backing strip;
- at least one longitudinally extending sealing body having one edge surface attached to said backing strip and its opposite free edge surface projecting from said backing strip, said backing strip and sealing body cooperating to form a sealing assembly;
- and
- a longitudinally extending barrier fin having first and second web portions joined along a common fold line to define an obtuse angle therebetween, said first web portion having one edge, opposite and parallel to said fold line, secured to said sealing assembly, said first web portion further extending substantially vertically from said backing strip to said fold line located substantially at the level of said free edge surface, and said second web portion extending from said fold line in a direction wherein it overhangs said free edge surface of said sealing body.
A method of forming a weatherstrip comprising the steps of:
- providing a longitudinally extending backing strip;
- affixing one edge surface of a transversely and longitudinally extending sealing body to the backing strip with the opposite edge surface free, the backing strip and sealing body cooperating to define a sealing assembly;
- forming a longitudinally extending barrier fin having first and second web portions defining an obtuse angle and joined together along edges thereof to form a common fold line;
- affixing an edge of the first web portion located opposite the fold line to the sealing assembly with the first web portion of the fin extending substantially vertically from the sealing assembly adjacent the sealing body with the fold line substantially at the same level as the opposite free edge surface of the sealing body, and with the second web portion extending from the fold line substantially across and overhanging the opposite free edge surface.
