Abstract

Abstract A weatherstrip assembly comprising an integral extrusion of polymeric material comprising a stiff portion adapted to be adhered on the vertical surface of a door with a flexible strip portion extending below the bottom edge of the door and along a threshold. A first magnetized strip is attached on the flexible portion and a second metal strip is adapted to be adhered to the surface of the threshold so that the strips will be face to face and releasably seal between the door and the threshold when the door is closed.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 162 words
A weatherstrip assembly adapted to seal between the bottom of an exterior door and an inner surface of its threshold, said assembly comprising: an integral polymeric extrusion comprising a stiff strip-like portion having first and second generally parallel edges, and a flexible strip-like portion extending from the second edge of said stiff portion and having an outer edge generally parallel to said second edge, said stiff and flexible portions defining an inner surface; means for attaching said stiff portion to the vertical surface of a said door with the flexible portion extending below the bottom edge of the door; a pair of magnetically attracted strips including a first strip attached on said inner surface along said flexible portion adjacent said outer edge, and a second strip; and means for attaching said second strip to the inner surface of a said threshold in a position to afford separable face-to-face contact of said strips due to magnetic attraction therebetween when the door is closed.
Claim 2
Dependent Claim 162 words
A weatherstrip assembly adapted to seal between the bottom of an exterior door and an inner surface of its threshold, said assembly comprising: an integral polymeric extrusion comprising a stiff strip-like portion having first and second generally parallel edges, and a flexible strip-like portion extending from the second edge of said stiff portion and having an outer edge generally parallel to said second edge, said stiff and flexible portions defining an inner surface; means for attaching said stiff portion to the vertical surface of a said door with the flexible portion extending below the bottom edge of the door; a pair of magnetically attracted strips including a first strip attached on said inner surface along said flexible portion adjacent said outer edge, and a second strip; and means for attaching said second strip to the inner surface of a said threshold in a position to afford separable face-to-face contact of said strips due to magnetic attraction therebetween when the door is closed.
Claim 3
Dependent Claim 49 words
A weatherstrip assembly according to claim 1 wherein said extrusion includes a flexible lip along said first edge and projecting normal to said inner surface to cover the adjacent edge of said layer of pressure-sensitive adhesive on said stiff portion when said stiff portion is adhered to said door.
Claim 4
Dependent Claim 34 words
A weatherstrip assembly according to claim 1 or claim 2 wherein said first strip attached to said flexible portion is of a flexible magnetized material, and said second strip is of magnetic stainless steel.
Claim 5
Dependent Claim 17 words
A weatherstrip assembly according to claim 1 further including release liners over said layers of pressure-sensitive adhesive.
Claim 6
Dependent Claim 18 words
A weatherstrip assembly according to claim 1 or claim 2 wherein said polymeric material comprises a thermoplastic rubber.
Claim 7
Dependent Claim 47 words
A weatherstrip assembly according to claim 1 wherein said means for attaching said stiff portion comprises a layer of pressure sensitive adhesive deposed on said inner surface along said stiff portion, and said means for attaching said second strip also comprises a layer of pressure sensitive adhesive.
