Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
A glazed closure assembly comprising: (a) a first pair of parallel spaced frame members made of synthetic resin and having a first pair of slots, respectively, facing toward each other; (b) a second pair of parallel spaced frame members, perpendicular to said first pair, made of synthetic resin and having a second pair of slots, respectively, facing toward each other; (c) a pair of parallel spaced attachments made of metal and mounted respectively in said first pair of slots, said attachments having a third pair of slots, respectively, facing toward each other and a pair of fastener-receiving means, respectively, remote from said third pair of slots and opening at the ends of said attachments which confront said second frame members; (d) gasket means disposed in said third pair of slots and said second pair of slots; (e) a pane of glass having its marginal edges supported by said gasket extending therearound; and (f) fastener means extending through said second frame members threadedly into said fastener-receiving means, whereby said attachments are connected endwise to said second pair of parallel spaced frame members.
Claim 2
Dependent Claim
181 words
A glazed closure assembly comprising: (a) a first pair of parallel spaced frame members made of synthetic resin and having a first pair of slots, respectively, facing toward each other; (b) a second pair of parallel spaced frame members, perpendicular to said first pair, made of synthetic resin and having a second pair of slots, respectively, facing toward each other; (c) a pair of parallel spaced attachments made of metal and mounted respectively in said first pair of slots, said attachments having a third pair of slots, respectively, facing toward each other and a pair of fastener-receiving means, respectively, remote from said third pair of slots and opening at the ends of said attachments which confront said second frame members; (d) gasket means disposed in said third pair of slots and said second pair of slots; (e) a pane of glass having its marginal edges supported by said gasket extending therearound; and (f) fastener means extending through said second frame members threadedly into said fastener-receiving means, whereby said attachments are connected endwise to said second pair of parallel spaced frame members.
Claim 3
Dependent Claim
89 words
A glazed closure assembly according to claim 1, each of said pair of attachments comprising an elongated channel-shaped structure having a length substantially equal to that of one of said first pair of frame members, said channel-shaped structure including a pair of sidewalls, an end wall extending between said sidewalls, and each of said fastener-receiving means comprising a pair of sockets mounted on said end wall respectively at the ends of said elongated structure and disposed in one of said first pair of slots in said first frame members.
Claim 4
Dependent Claim
102 words
A glazed closure assembly according to claim 2, each of said pair of first frame members comprising a pair of sidewalls and a partition extending therebetween, including a pair of first locking projections extending from said sidewalls of said each first frame member toward each other into the first slot, each of said first locking projections having a shoulder facing toward said partition, and a pair of wedge-shaped locking projections extending from the sidewalls of said attachment, and each having a surface held against said shoulder and a slant surface held out of engagement with said sidewall of said first frame member.
Claim 5
Dependent Claim
52 words
A glazed closure assembly according to claim 2, including a pair of locking projections extending respectively from said sidewalls toward each other into said third slot, said gasket having in its opposite walls a pair of recesses opening away from each other, said locking projections being lockingly fitted respectively in said recesses.
