Abstract
Abstract A nonbracing self-framing window buck frame or surround for forming a framed window opening in a cast concrete wall or the like. The buck frame or surround comprises a support frame made of channel members arranged end-to-end to form a substantially rectangular framework. A window frame is fit within the framework formed by the channel members, such that a peripheral mounting flange on the window frame abuts one side of the framework. A frame structure adapted to receive nails or other fasteners abuts the peripheral mounting flange of the window frame, and means are provided for securing the support frame and frame structure together, with the peripheral mounting flange on the window frame being held securely between the frame structure and the support frame. The buck frame or surround, including the self-contained window frame, is positioned between wall forms, and concrete is poured around the buck frame or surround. After the concrete has cured, the forms are removed. The buck frame or surround remains in the concrete wall, forming a self-framed window opening having a sturdy, finished exterior casing and an interior framing structure to which interior wallboard and other window sash and trim can be readily attached.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
249 words
A nonbracing, self-framing window buck and frame for forming a framed window opening in a cast concrete wall or the like, said window buck and frame comprising four elongate, rigid channel members, each of said channel members comprising a substantially flat base, with first and second legs extending from mutually respective longitudinal side edges of said base, so that said channel members have a substantially U-shaped cross section, said channel members further being attached together in substantially end-to-end arrangement to form the periphery of a framework circumscribing a substantially rectangular opening, with the flat base of said channel members facing said opening and with the legs of said channel members extending outwardly from said opening; a window frame adapted to fit within said opening, said window frame having a peripheral mounting flange which is adapted to abut the outside face of mutually respective flat legs of said channel members at one side of said framework; four elongate members attached together in substantially end-to-end arrangement to form a substantially rectangular, frame structure, said frame structure being adapted to abut, along one of its rectangular, side edge faces, the peripheral mounting flange of said window frame; and means for firmly connecting said first legs of said channel members at least at spaced intervals therealong, to said frame structure, such that said frame structure and said framework are in substantial registry with each other, with said peripheral mounting flange on said window frame held securely between said frame structure and said framework.
Claim 2
Dependent Claim
249 words
A nonbracing, self-framing window buck and frame for forming a framed window opening in a cast concrete wall or the like, said window buck and frame comprising four elongate, rigid channel members, each of said channel members comprising a substantially flat base, with first and second legs extending from mutually respective longitudinal side edges of said base, so that said channel members have a substantially U-shaped cross section, said channel members further being attached together in substantially end-to-end arrangement to form the periphery of a framework circumscribing a substantially rectangular opening, with the flat base of said channel members facing said opening and with the legs of said channel members extending outwardly from said opening; a window frame adapted to fit within said opening, said window frame having a peripheral mounting flange which is adapted to abut the outside face of mutually respective flat legs of said channel members at one side of said framework; four elongate members attached together in substantially end-to-end arrangement to form a substantially rectangular, frame structure, said frame structure being adapted to abut, along one of its rectangular, side edge faces, the peripheral mounting flange of said window frame; and means for firmly connecting said first legs of said channel members at least at spaced intervals therealong, to said frame structure, such that said frame structure and said framework are in substantial registry with each other, with said peripheral mounting flange on said window frame held securely between said frame structure and said framework.
Claim 3
Dependent Claim
152 words
A window buck and frame as claimed in claim 1, wherein the first legs of said channel members at said one side of said framework have widths at least the width of the peripheral mounting flange on said window frame, the members of said frame structure have a thickness abutting said peripheral mounting flange substantially the same as the widths of the mutually respective first legs of the channel members, and the means for connecting said first legs at said one side of said framework to said frame structure comprises spaced apart attachment tabs integrally attached at mutually respective ends to the outwardly extending edges of said first legs, said attachment tabs extending substantially perpendicular from said first legs so as to lie substantially flatwise against the outside perimeter of respective members of said frame structure, and means are provided for securing said attachment tabs to said members of said frame structure.
Claim 4
Dependent Claim
49 words
A window buck frame as claimed in claim 2, wherein the means for securing the attachment tabs to the members of said frame structure comprises openings in said attachment tabs, said openings being adapted to receive fasteners for attaching said attachment tabs to said members of said frame structure.
Claim 5
Dependent Claim
152 words
A window buck frame as claimed in claim 1, wherein the first legs of said channel members at said one side of said framework have widths at least the width of the peripheral mounting flange on said window frame, the members of said window frame structure have a thickness abutting said peripheral mounting flange substantially the same as the widths of the mutually respective first legs of the channel members, and the means for connecting said first legs at said one side of said framework to said frame structure comprises substantially flat lips integrally attached to the outwardly extending edges of the respective first legs of said channel members, said flap lips extending substantially perpendicularly from said first legs so as to lie substantially flatwise against the outer perimeter of respective members of said frame structure, and means are provided for securing said flat lips to said members of said frame structure.
Claim 6
Dependent Claim
50 words
A window buck frame as claimed in claim 4, wherein the means for securing the flat lips to the members of said frame structure comprises openings spaced along said flat lips, said openings being adapted to receive fasteners for attaching said flat lips to said members of said frame structure.
Claim 7
Dependent Claim
49 words
A window buck and frame as claimed in claim 1, wherein the means for connecting the first legs of said channel members to said frame structure comprises opening spaced along said first legs, said openings being adapted to receive fasteners for attaching said first legs to said frame structure.
Claim 8
Dependent Claim
47 words
A window buck and frame as claimed in claim 1, wherein the second legs of said channel members are provided with apertures spaced therealong, said apertures being adapted to receive fasteners for attaching the window buck and frame to the inside face of a concrete wall form.
Claim 9
Dependent Claim
55 words
A window buck and frame as claimed in claim 1, wherein edge flanges are provided along the projecting edges of the second legs of said channel members, with said edge flanges being integrally attached to the projecting edges of said second legs and extending therefrom generally backwardly toward said first legs of said channel members.
Claim 10
Dependent Claim
32 words
