Abstract
Improved installation fins (28, 76) for window or door assemblies (88, 98) are provided which include structure (46) defining an elongated fold line (73) in the fins (28, 76). The structure (46) includes a plurality of elongated, discrete, parallel, aligned depressions (48) formed in one face (38) of the fin (28 76); the depressions (48) are oriented with the longitudinal axes thereof at an oblique angle of from about 10.degree.-40.degree. relative to the longitudinal axis of the fin (28, 76). The fins (28, 76) are preferably fabricated from aluminum, and the depressions (48) are formed therein by knurling.
Claims58
An installation fin adapted for attachment to the frame of a fenestration product and comprising:
- an elongated thin body presenting a pair of opposed faces and a pair of elongated, opposed, spaced apart, inner and outer side margins, said inner side margin including structure for attachment of the fin to said fenestration product;
- and
- structure defining an elongated fold line generally parallel with and proximal to said inner side margin for permitting selective pivotal movement of an outer section of the fin body about the fold line,
- said fold line-defining structure including a plurality of elongated, aligned depressions formed in at least one face of said body, said depressions being oriented with the longitudinal axes thereof at an oblique angle relative to the longitudinal axis of said body to cooperatively define said fold line, said depressions being discrete and axially spaced from each other.
A fenestration assembly adapted to be mounted in an opening in a wall of a building and comprising:
- a frame assembly presenting at least a top and opposite side members, each of said members having an outer surface;
- a fenestration product within the confines of said frame assembly and operably coupled thereto;
- and
- an elongated installation fin secured to the outer surface of said top and side frame members, each of said fins including
- an elongated, thin body presenting a pair of opposed faces and a pair of elongated opposed inner and outer side margins, said inner side margin being secured to a corresponding frame member;
- and
- structure defining an elongated fold line generally parallel with and proximal to said inner side margin for permitting selective pivotal movement of an outer section of the fin body about the fold line and away from adjacent frame member,
- said fold line-defining structure including a plurality of elongated, aligned depressions formed in at least one face of said body, said depressions being oriented with the longitudinal axes thereof at an oblique angle relative to the longitudinal axis of said body to cooperatively define said fold line, said depressions being discrete and axially spaced from each other.
In a metallic body presenting opposite faces and having structure defining an elongated fold line permitting selective pivoting of at least one body section about the fold line, improved fold line-defining structure comprising a plurality of elongated, aligned depressions formed in at least one face of said body and oriented with the longitudinal axes thereof at an oblique angle relative to said fold line, said depressions being discrete and axially spaced from each other.
