Abstract
Abstract Frame members are assembled for two components in such a way that a flange on one component butts against a flange on the other component to form a closed hollow ridge along one side of the frame member. A projection completes the closed hollow ridge, and the projection functions to guide the flanges into correct abutting relationship.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
A window or door frame member having a main hollow cross section and a closed hollow ridge extending along at least one of its sides, said frame member being assembled from two components which include a. a first component having a flange extending substantially perpendicularly to a portion of said first component, which portion forms one side of the main hOllow cross section of the frame member and b. a second component having a flange extending substantially perpendicularly to an extension of a portion of said second component, which portion forms an adjacent side of the main hollow cross section of the frame member, said closed hollow ridge being produced upon assembly of said two components by abutting the end of the flange of said first component against the flange on said second component such that the flange on said first component and the flange on said second component form two adjacent sides of said hollow closed ridge, and said second component being provided with at least one projection which engages with a corner of the first component between the flange of the first component and the portion of the first component which forms the one side of the main hollow cross section, as the two components are brought together, to guide the end of the flange of the first component into abutting relationship with the flange of the second component.
Claim 2
Dependent Claim
231 words
A window or door frame member having a main hollow cross section and a closed hollow ridge extending along at least one of its sides, said frame member being assembled from two components which include a. a first component having a flange extending substantially perpendicularly to a portion of said first component, which portion forms one side of the main hOllow cross section of the frame member and b. a second component having a flange extending substantially perpendicularly to an extension of a portion of said second component, which portion forms an adjacent side of the main hollow cross section of the frame member, said closed hollow ridge being produced upon assembly of said two components by abutting the end of the flange of said first component against the flange on said second component such that the flange on said first component and the flange on said second component form two adjacent sides of said hollow closed ridge, and said second component being provided with at least one projection which engages with a corner of the first component between the flange of the first component and the portion of the first component which forms the one side of the main hollow cross section, as the two components are brought together, to guide the end of the flange of the first component into abutting relationship with the flange of the second component.
Claim 3
Dependent Claim
34 words
A frame member according to claim 1, in which the closed hollow ridge has four sides comprising the flange of said first component, the flange of said second component, said projection and said extension.
Claim 4
Dependent Claim
17 words
A frame member according to claim 1, in which the projection comprises a plurality of spaced projections.
Claim 5
Dependent Claim
42 words
A frame member according to claim 1, in which the flange of the first component has a lip directed towards the extension of the second component and seated in a recess in the flange extending from the extension of the second component.
Claim 6
Dependent Claim
22 words
A frame member according to claim 1, in which the projection has a ledge for engaging the corner of the first component.
Claim 7
Dependent Claim
53 words
A frame member according to claim 1 in which the projection is cut away to provide a spigot for location in a corresponding socket in the first component, the spigot and socket being equidistant from corresponding ends of their respective components thereby serving to longitudinally locate the components with respect to each other.
Claim 8
Dependent Claim
15 words
A frame member according to claim 1 in which the two components are bonded together.
