Abstract
Abstract A curtain wall or paneling system for concealing and beautifying an existing structural wall features a pair of elongated, upper cap and lower sill-forming channel members which are attached in predetermined, vertically spaced relation on the existing wall and which support and hold a plurality of transversely spaced apart, vertically elongated metallic studs or pilasters and decorative wall panels. The length of the studs and wall panels are correlated to the spacing between and depth of the upper cap and lower sill channel members, so that they may be easily lifted into and out of engagement with the cap and sill channel members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
A wall comprising: (a) a pair of opposed, elongated channel-form frame members disposed in vertically spaced apart, generally coplanar relation and defining, respectively, upper and lower channels opening toward one another, said lower channel being shallower than said upper channel; (b) a plurality of vertically arranged, horizontally spaced apart, hollow-form, studs of integral, one-piece construction having upper and lower end portions extending, respectively, into said upper and lower channels, each of said studs including longitudinally coextensive, outward projecting, panel-separating means; (c) a rectangular wall panel extending between said channel-form frame members and spanning the space between a pair of said studs and having opposite side edges disposed in substantial abutment with the panel-separating means of each of said pair of studs, and having catch means disposed adjacent a side edge thereof, said panel and studs having length dimensions permitting their ready removal from said channel-form frame members simply by lifting their lower ends above and moving them outwardly from said lower channel; and (d) a manually operable latch carried by at least one of said studs and accessible through a slot formed in the panel-separating means of the stud, said latch being selectively movable to engage the catch means of said panel and thereby lock said panel to the stud.
Claim 2
Dependent Claim
210 words
A wall comprising: (a) a pair of opposed, elongated channel-form frame members disposed in vertically spaced apart, generally coplanar relation and defining, respectively, upper and lower channels opening toward one another, said lower channel being shallower than said upper channel; (b) a plurality of vertically arranged, horizontally spaced apart, hollow-form, studs of integral, one-piece construction having upper and lower end portions extending, respectively, into said upper and lower channels, each of said studs including longitudinally coextensive, outward projecting, panel-separating means; (c) a rectangular wall panel extending between said channel-form frame members and spanning the space between a pair of said studs and having opposite side edges disposed in substantial abutment with the panel-separating means of each of said pair of studs, and having catch means disposed adjacent a side edge thereof, said panel and studs having length dimensions permitting their ready removal from said channel-form frame members simply by lifting their lower ends above and moving them outwardly from said lower channel; and (d) a manually operable latch carried by at least one of said studs and accessible through a slot formed in the panel-separating means of the stud, said latch being selectively movable to engage the catch means of said panel and thereby lock said panel to the stud.
Claim 3
Dependent Claim
43 words
A wall according to claim 1, wherein each of said channel-form frame members is provided at longitudinally spaced intervals therealong with stud-locating fingers, and said studs have their upper and lower end portions detachably engaged with the stud-locating fingers of said frame members.
Claim 4
Dependent Claim
33 words
A wall according to claim 1, wherein each of said studs contains a longitudinally extending, perforated, bracket-anchoring strip, and said panel-separating means defines a longitudinally extensive, outwardly opening access channel to said strip.
Claim 5
Dependent Claim
59 words
A wall according to claim 1, wherein the panel-separating means of each of said studs consists of a pair of integral, transversely spaced apart ribs extending longitudinally of said stud and projecting outwardly therefrom, each of said ribs forming on said stud a longitudinally coextensive, right angular, entrant corner seat for a side edge of an adjacent wall panel.
Claim 6
Dependent Claim
25 words
A wall according to claim 1, wherein each of said studs is hollow and includes an internal, longitudinally coextensive chamber containing a perforated, bracket-anchoring strip.
Claim 7
Dependent Claim
38 words
A wall according to claim 1, wherein each of said channel-form frame members is formed at longitudinally spaced intervals with openings through which a fastener may be passed to secure said frame member to an adjacent supporting wall.
Claim 8
Dependent Claim
157 words
In a wall paneling system; a panel-positioning stud comprising an elongated, hollow column of integral, one-piece construction formed with a longitudinally coextensive internal chamber of generally rectangular cross-section and a pair of relatively spaced apart, longitudinally coextensive, outwardly projecting ribs, said ribs defining on an outer face of said column a pair of transversely spaced apart, longitudinally coextensive, entrant corner, panel-receiving seats separated by a longitudinally coextensive, outwardly opening channel communicating with and disposed in generally perpendicularly intersecting relation to the internal chamber of said column; a perforated, bracket-anchoring strip of rectangular cross-section carried in the internal chamber of said column and accessible through the channel defined by said ribs; and a manually-operable, laterally extensible latch carried in the internal chamber of said column and accessible through said channel, said latch being selectively movable between a position of confinement within the chamber of said column and a laterally extended position adjacent the panel-receiving seats of said column.
Claim 9
Dependent Claim
157 words
