Abstract
Abstract A bracket for fixing a prefabricated window to roof boards or sheathing in an inclined roof is already secured to the window main frame during the factory assembling of the window. The presecuring of the bracket is effected by a screw inserted through a hole in a positioning member which through a connecting portion consisting of a bridge and a rodlike member is integrally connected with one side edge of a first leg of the bracket. The first leg continues at its lower side into a second leg at right angle to the first leg. Before packaging the window for transportation the first and second legs are swung into abutment on the main frame by turning around the connecting portion. When the window is to be installed in the roof the first and second legs are swung through an angle of 180° until the first leg abuts against the positioning member. In this position mounting screws are through the overlapping holes screwed into the main frame. Then the window is secured to the roof boards by driving screws or nails through the holes in the second leg into the boards.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A prefabricated window for installation in an inclined roof of the type having a supporting structure, a sheathing secured to the supporting structure, and a roofing fixed to the sheathing; the window comprising a main frame with an outer sidewall and a plurality of mounting brackets, wherein each mounting bracket comprises a first leg; a second leg forming an angle with the first leg; a positioning member having a hole for a mounting means; and a portion connecting the first leg integrally with the positioning member; the positioning member being secured to the outer sidewall of the main frame in such a position that during transportation of the window the first leg is abutting against the main frame and the second leg is situated below the main frame, whereas during installation of the window the first leg is swung into a position in which it abuts against the positioning member and the second leg is outside the main frame and ready for fixation to the sheathing; the connecting portion defining the axis of said swinging of the first and second legs in relation to the positioning member.
Claim 2
Dependent Claim
187 words
A prefabricated window for installation in an inclined roof of the type having a supporting structure, a sheathing secured to the supporting structure, and a roofing fixed to the sheathing; the window comprising a main frame with an outer sidewall and a plurality of mounting brackets, wherein each mounting bracket comprises a first leg; a second leg forming an angle with the first leg; a positioning member having a hole for a mounting means; and a portion connecting the first leg integrally with the positioning member; the positioning member being secured to the outer sidewall of the main frame in such a position that during transportation of the window the first leg is abutting against the main frame and the second leg is situated below the main frame, whereas during installation of the window the first leg is swung into a position in which it abuts against the positioning member and the second leg is outside the main frame and ready for fixation to the sheathing; the connecting portion defining the axis of said swinging of the first and second legs in relation to the positioning member.
Claim 3
Dependent Claim
76 words
A prefabricated window according to claim 1, and wherein the mounting bracket is made of a single piece of sheet metal by punching, stamping and bending, thereby defining a lower side and a first and a second side edge on the first leg which at its lower side continues into the second leg and at its first side edge continues into the positioning member, the second leg being at a right angle to the first leg.
Claim 4
Dependent Claim
18 words
A prefabricated window according to claim 2, and wherein the positioning member is flush with the first leg.
Claim 5
Dependent Claim
22 words
A prefabricated window according to claim 2, and wherein the positioning member is perpendicular to both the first and the second leg.
Claim 6
Dependent Claim
63 words
A prefabricated window according to claim 4, and wherein the positioning member has a first and a second opposite side edge and the connection portion includes a bridge connecting the central portion of the first side edge of the positioning member with the middle of a rodlike member which at its ends is integral with the first side edge of the first leg.
Claim 7
Dependent Claim
71 words
A prefabricated window according to claim 5, and wherein the first leg has holes for mounting screws or mounting nails for securing the first leg to the window frame; the positioning member has holes corresponding to the holes in the first leg when this has been swung into the installation position; and the second leg has holes for mounting screws or mounting nails for securing the mounting bracket to the sheathing.
Claim 8
Dependent Claim
50 words
A prefabricated window according to claim 6, and wherein the second side edge of the positioning member carries a protrusion adapted to engage with a cut-out in the second edge of the first leg when the positioning member and the first leg are in mutual abutment in the installation position.
