Abstract

Abstract The disclosed invention concerns seals for double doors or windows, i.e. those which have stiles which meet edge-to-edge in the closed situation, in which a strip-like fitting on one door overlaps the other when closed and thus elastically deforms and presses a sealing strip against the coplanar surfaces of the adjacent stiles; the seal strip is formed so that it can roll laterally to accommodate uneven surfaces.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 237 words
The combination of double doors or windows having adjacent vertical edges and a clearance gap defined by such edges whdn tghedoors are in a closed condition, a seal for the doors comprising a rigid strip-like element and an elastomeric strip, said element attached to one side of one of said doors and having a flange formed with a flat surface facing and overlapping the gap between the adjacent vertical edges of said doors and spaced from the surfaces of said doors, the flat surface of said flange facing said doors having formed therein a longitudinal channel of open, reentrant section which opens opposite the gap and divides the flat surface of the flange into margins extending laterally from the channel, and the elastomeric seal-strip has a portion of its cross section retained in said channel and an exposed portion of its cross section protruding from said channel, the protruding portion of said elastomeric strip having in a relaxed state a lateral dimension exceeding the channel width and the gap width, said exposed portion being elastically yieldable having freedom to deform and laterally roll in the space defined on either side of the protruding portion of the elastomeric strip and between the flange and the doors, and disposed to be backed up by the margins of the flange and bear directly and resiliently seal against the surfaces of the doors when said doors are in a closed condition.
Claim 2
Dependent Claim 237 words
The combination of double doors or windows having adjacent vertical edges and a clearance gap defined by such edges whdn tghedoors are in a closed condition, a seal for the doors comprising a rigid strip-like element and an elastomeric strip, said element attached to one side of one of said doors and having a flange formed with a flat surface facing and overlapping the gap between the adjacent vertical edges of said doors and spaced from the surfaces of said doors, the flat surface of said flange facing said doors having formed therein a longitudinal channel of open, reentrant section which opens opposite the gap and divides the flat surface of the flange into margins extending laterally from the channel, and the elastomeric seal-strip has a portion of its cross section retained in said channel and an exposed portion of its cross section protruding from said channel, the protruding portion of said elastomeric strip having in a relaxed state a lateral dimension exceeding the channel width and the gap width, said exposed portion being elastically yieldable having freedom to deform and laterally roll in the space defined on either side of the protruding portion of the elastomeric strip and between the flange and the doors, and disposed to be backed up by the margins of the flange and bear directly and resiliently seal against the surfaces of the doors when said doors are in a closed condition.
Claim 3
Dependent Claim 48 words
The combination according to claim 1, in which the said flat surface of the flange extends in a plane substantially parallel to the plane of the surfaces of the closed doors, and the protruding portion of the elastomeric strip is a tubular section when in a relaxed state.
Claim 4
Dependent Claim 26 words
The combination according to claim 1 in which said vertical edges are rebated, complementary and overlap each other when the doors are in a closed condition.
Claim 5
Dependent Claim 19 words
The combination according to claim 1 in which said vertical edges are of arcuate section in the horizontal sense.
