Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A cabinet comprising: a corner member having a plurality of brackets extending therefrom and positioned normal to one another. a plurality of frame members corresponding to said plurality of brackets, one of said frame members being slidably positioned over each of said brackets and abutting said corner member; a flange extending upwardly from each of said plurality of frame members; and a top panel having a downwardly extending lip formed around its periphery, said top panel being positioned atop said plurality of frame members such that said lip on said top panel is disposed exteriorly of said flange on said plurality of frame members such that said flange extends upwardly toward said top panel at a point inside outer periphery.
Claim 2
Dependent Claim
120 words
A cabinet comprising: a corner member having a plurality of brackets extending therefrom and positioned normal to one another. a plurality of frame members corresponding to said plurality of brackets, one of said frame members being slidably positioned over each of said brackets and abutting said corner member; a flange extending upwardly from each of said plurality of frame members; and a top panel having a downwardly extending lip formed around its periphery, said top panel being positioned atop said plurality of frame members such that said lip on said top panel is disposed exteriorly of said flange on said plurality of frame members such that said flange extends upwardly toward said top panel at a point inside outer periphery.
Claim 3
Dependent Claim
14 words
The cabinet of claim 1, wherein said frame members are bonded to one another.
Claim 4
Dependent Claim
45 words
The cabinet of claim 1, further comprising a gasket attached to said flange on each of said plurality of frame members, a portion of said gasket extending between said top panel and said flange to effect a seal between said top panel and said flange.
Claim 5
Dependent Claim
38 words
The cabinet of claim 1, wherein said top panel further comprises lateral edges, and wherein said corner member further comprise a projection extending upwardly therefrom and having a lateral surface abutting said lateral edges of said top panel.
Claim 6
Dependent Claim
20 words
The cabinet of claim 4, wherein said projection has a height substantially corresponding to the height of said top panel.
Claim 7
Dependent Claim
42 words
The cabinet of claim 1, wherein said top panel further comprises rectangular cutouts defined in each corner of said top panel, and wherein said corner member further comprises a projection extending upwardly therefrom and projecting through said cutouts in said top panel.
Claim 8
Dependent Claim
100 words
The cabinet of claim 3, wherein said gasket comprises: a sealing device including a compressible, resilient elongate head and a pair of legs extending downwardly from said elongate head, said flange being positioned between said legs; and a conductive material disposed between said legs in contact with said flange and extending upwardly along the outer surface of one of said legs and a portion of said elongate head, such that said conductive material and said compressible resilient head may directly contact said panel for substantially shielding said joint against the passage of RF waves, moisture and debris through said joint.
Claim 9
Dependent Claim
25 words
The cabinet of claim 6, wherein said rectangular cutouts define lateral edges and said projection defines a lateral surface positioned to abut said lateral edges.
