Frame construction having arcuate corners and a continuous feature strip

Claim 2

In a frame construction for a polygonal opening in a building wall or the like, the combination of: a plurality of angularly disposed frame members lying in a common plane, each frame member comprising main web, flange means including a front flange directed internally of said opening for retaining associated panels, and a second front flange directed exteriorly of said opening as a continuation of said beforementioned front flange and adapted to overlie edge margins of said building wall at said opening; said second front flange providing a front groove for retaining a molding strip means; a molding strip means retained in said groove and extending along said second flange; means on said front flange defining a rearwardly directed back caulking channel; and a corner joint member having in plan the configuration of a sector of a circle including an arcuate outer edge joining outer edges of said frame members and an arcuate inner edge, and means in cross section corresponding at front portions to the groove and molding strip means on said second front flanges, said corner member including means receivable within said front flange grooves for interlocking engagement with said frame members and extending at least to said molding strip means; said molding strip means on said frame members and means corresponding thereto on said corner member providing a continuously forwardly facing feature strip means of uniform width and extending from one frame member to the other frame member in the form of an arc subtending the angle between end edges of contiguous frame members.

Claim 3

In a frame construction for a polygonal opening in a wall or the like, the combination of: at least two frame members angularly disposed and having transverse end faces lying in planes which intersect at approximately the intersection of inner edges of said frame members; each frame member having a flange provided with a front facing longitudinal groove means defined by parallel return portions providing molding strip retention means; a molding strip retained in said groove means and presenting a front surface means and having strip end edges terminating in spaced relation to the transverse end faces of said frame members; and corner means extending between said frame member end faces to provide a continuous curved corner appearance joining said frame members; said corner means including a body portion having the shape of a sector of a circle with its center at the said intersection of said planes and having a continuing outer peripheral edge in the form of an arc joining outer edges of said continuous frame members; said body portion having inner and outer edge portions corresponding in cross section to said frame members and abutting therewith at said planes; said corner means including tongue portions extending into said groove means of the frame members and terminating at least at the strip end edges of the molding strip retained in said frame member; said corner body and tongue portions having outwardly facing surface means corresponding to the molding strip front surface means and adapted to abut said strip end edges, whereby the front surface means of the molding strip means and corner members provide a continuous unbroken in appearance feature strip means framing said opening with rounded corners.

Claim 4

In a frame construction for a polygonal opening in a wall or the like, the combination of: at least two frame members angularly disposed and having transverse end faces lying in planes which intersect at approximately the intersection of inner edges of said frame members; each frame member having a flange provided with a front facing longitudinal groove means defined by parallel return portions providing molding strip retention means; a molding strip retained in said groove means and presenting a front surface means and having strip end edges terminating in spaced relation to the transverse end faces of said frame members; and corner means extending between said frame member end faces to provide a continuous curved corner appearance joining said frame members; said corner means including a body portion having the shape of a sector of a circle with its center at the said intersection of said planes and having a continuing outer peripheral edge in the form of an arc joining outer edges of said continuous frame members; said body portion having inner and outer edge portions corresponding in cross section to said frame members and abutting therewith at said planes; said corner means including tongue portions extending into said groove means of the frame members and terminating at least at the strip end edges of the molding strip retained in said frame member; said corner body and tongue portions having outwardly facing surface means corresponding to the molding strip front surface means and adapted to abut said strip end edges, whereby the front surface means of the molding strip means and corner members provide a continuous unbroken in appearance feature strip means framing said opening with rounded corners.

Claim 5

In a frame construction as stated in claim 2 wherein said corner means includes tongue portions having tabs projecting therefrom beneath the molding strip means on the frame members and having front surfaces corresponding in color to the color of said front surface means whereby separation of said molding strip end edge with respect to the end of said tongue portion is unnoticeable.

Claim 6

In a frame construction as stated in claim 2 wherein said molding strip means is a plastic material.

Claim 7

In a frame construction as claimed in claim 2 wherein said front surface means of said corner member and of said molding strip means and the material of the frame means and corner member are of contrasting colors.
