Threshold with magnetic weather stripping

Claim 2

A threshold assembly for mounting on a door and a door sill comprising: a. a threshold plate formed of non-magnetically attracted material, said plate having a first stepped portion thereof with the substantially vertical face extending medially along the bottom edge of said door: b. said first stepped portion, in turn comprising: (1) a riser portion; (2) a stair portion extending from the lower edge of said portion inwardly toward and beyond the interior surface of said door; (3) a channel in the face of said riser portion; (4) a magnetically attracted strip mounted in said channel; c. a saddle portion extending from the upper edge of said riser portion outwardly beyond the exterior surface of said door; d. attachment means for attaching said threshold plate to said door sill; e. a second stepped portion on the bottom edge of said door having the lowermost portion thereof corresponding to said stair portion of said first stepped portion and the uppermost portion thereof corresponding to said saddle portion; f. magnet-mounting means for attachment to said lowermost portion of said second stepped portion, said magnet-mounting means, in turn comprising; (1) a slot extending substantially vertically adjacent said lowermost portion; (2) a guard plate extending substantially horizontally adjacent said stair portion; g. magnet holding assembly mountable to said magnet-mounting means, in turn comprising: (1) a T-shaped mounted flange for mounting within said slot thereof with the stem protruding therefrom. (2) an extensible bellows attached at one end to said stem permitting the horizontally extending movement of the magnet assembly when magnet attraction exists and the horizontally retracting movement of the magnet assembly when magnet attraction ceases; (3) a pocket with one side thereof attached at the other end of said extensible bellows; and, (4) a magnet strip mounted in said pocket.

Claim 3

A threshold assembly as described in claim 1, wherein said lowermost portion of said second stepped portion is integrally formed with said magnet-mounting means and is mounted to the bottom edge of the interior surface of said door.

Claim 4

A threshold assembly as described in claim 4, wherein a door cap assembly for mounting on the bottom edge of said door, comprises: a. an exterior facing plate extending along the bottom edge of the exterior surface of said door, and b. door cap means extending horizontally and integrally formed with said magnet-mounting means and said second stepped portion.

Claim 5

A threshold assembly as described in claim 1 wherein said magnet-holding assembly comprises a vinyl extrusion which integrally forms said T-shaped mounting flange, said extensible bellows and said pocket.

Claim 6

A threshold assembly as described in claim 2 wherein the exterior face of said pocket opposite the side attached to said bellows has rib members extending longitudinally for facilitating disengagement of magnetic sealing during opening of the door.

Claim 7

A threshold assembly as described in claim 3 wherein said door cap means further includes vertical stiffening members to prevent inadvertent crimping of said guard plate.

Claim 8

A threshold assembly for mounting on a door and a door sill comprising: a. a threshold plate formed of nonmagnetically attracted material, said plate having a first stepped portion thereof with the substantially vertical face extending medially along the bottom edge of said door; b. said first stepped portion, in turn, comprising: (1) a riser portion; (2) a stair portion extending from the lower edge of said riser portion inwardly toward and beyond the interior surface of said door; (3) a channel in the face of said riser channel; (4) a magnetically attracted strip mounted in said channel. c. a saddle portion extending from the upper edge of said riser portion outwardly beyond the exterior surface of said door; d. attachment means for attaching said threshold plate to said door sill. e. a door cap assembly for mounting on the bottom edge of said door, in turn, comprising: (1) a second stepped portion on the bottom edge of said door having the lowermost portion thereof corresponding to said stair portion of said first stepped portion and the uppermost portion thereof corresponding to said saddle portion; (2) an exterior facing plate extending along the bottom edge of the exterior surface of said door; (3) door cap means extending horizontally and integrally formed with said second stepped portion and said exterior facing plate; f. magnet-mounting means for attachment to said lowermost portion of said second stepped portion, said magnet-mounting means, in turn, comprising: (1) a slot extending substantially vertically adjacent said lowermost portion; (2) a guard plate extending substantially horizontally adjacent said stair portion; g. magnet holding assembly mountable to said magnet-mounting means, in turn, comprising: (1) a T-shaped mounting flange for mounting within said slot thereof with the stem protruding therefrom: (2) an extensible bellows attached at one end to said stem permitting the horizontally extending movement of the magnet assembly when magnetic attraction ceases; (3) a pocket with one side thereof attached at the other end of said extensible bellows; (4) a magnet strip mounted in said pocket.

Claim 9

A threshold assembly for mounting on a door and a door sill comprising: a. a threshold plate formed of nonmagnetically attracted material, said plate having a first stepped portion thereof with the substantially vertical face extending medially along the bottom edge of said door; b. said first stepped portion, in turn, comprising: (1) a riser portion; (2) a stair portion extending from the lower edge of said riser portion inwardly toward and beyond the interior surface of said door; (3) a channel in the face of said riser channel; (4) a magnetically attracted strip mounted in said channel. c. a saddle portion extending from the upper edge of said riser portion outwardly beyond the exterior surface of said door; d. attachment means for attaching said threshold plate to said door sill. e. a door cap assembly for mounting on the bottom edge of said door, in turn, comprising: (1) a second stepped portion on the bottom edge of said door having the lowermost portion thereof corresponding to said stair portion of said first stepped portion and the uppermost portion thereof corresponding to said saddle portion; (2) an exterior facing plate extending along the bottom edge of the exterior surface of said door; (3) door cap means extending horizontally and integrally formed with said second stepped portion and said exterior facing plate; f. magnet-mounting means for attachment to said lowermost portion of said second stepped portion, said magnet-mounting means, in turn, comprising: (1) a slot extending substantially vertically adjacent said lowermost portion; (2) a guard plate extending substantially horizontally adjacent said stair portion; g. magnet holding assembly mountable to said magnet-mounting means, in turn, comprising: (1) a T-shaped mounting flange for mounting within said slot thereof with the stem protruding therefrom: (2) an extensible bellows attached at one end to said stem permitting the horizontally extending movement of the magnet assembly when magnetic attraction ceases; (3) a pocket with one side thereof attached at the other end of said extensible bellows; (4) a magnet strip mounted in said pocket.

Claim 10

A threshold assembly as described in claim 7 wherein said magnet-holding assembly comprises a vinyl extrusion which integrally forms said T-shaped mounted flange, said extensible bellows and said pocket.

Claim 11

A threshold assembly as described in claim 8 wherein the exterior face of said pocket opposite the side attached to said bellows has rib members extending longitudinally for facilitating disengagement of magnet sealing during opening of the door.

Claim 12

A threshold assembly as described in claim 7 wherein said door cap means further includes vertical stiffening members to prevent inadvertent crimping of said guard plate.
