Abstract
Abstract A metal case having an adaptable capability between a lateral file or a cabinet which includes an inner framework comprised of a plurality of corrugated metal panels, each having a similar cross-sectional configuration and substantially extending the depth and length of the case. The panels are arranged horizontally and vertically to form a box-like structure which may be encased in a one-piece, metal outer wrapper and finished with a top and a base pan, thereby concealing spot welds which partially secure the inner framework to the outer wrapper. The inner framework is further secured to the outer wrapper by adhesive, which also provides acoustical insulation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
A file cabinet having an inner framework comprising: a plurality of vertically oriented corrugated metal side panels which extend substantially the depth of said cabinet; a plurality of horizontally oriented corrugated metal panels which extend substantially the length of its corresponding side, wherein said horizontally oriented panels comprise a top panel and a bottom panel of said cabinet; said corrugated top, bottom and side panels including ridges and troughs, said ridges located near the outer edge of each panel and said troughs located between said ridges wherein said troughs of said top and bottom panels complementarily mate with and are welded to said troughs of said side panels, thereby forming a box-like structure; and a substantially one-piece metal outer wrapper disposed around a portion of at least one of said side panels and an adjacent side.
Claim 2
Dependent Claim
136 words
A file cabinet having an inner framework comprising: a plurality of vertically oriented corrugated metal side panels which extend substantially the depth of said cabinet; a plurality of horizontally oriented corrugated metal panels which extend substantially the length of its corresponding side, wherein said horizontally oriented panels comprise a top panel and a bottom panel of said cabinet; said corrugated top, bottom and side panels including ridges and troughs, said ridges located near the outer edge of each panel and said troughs located between said ridges wherein said troughs of said top and bottom panels complementarily mate with and are welded to said troughs of said side panels, thereby forming a box-like structure; and a substantially one-piece metal outer wrapper disposed around a portion of at least one of said side panels and an adjacent side.
Claim 3
Dependent Claim
21 words
The file cabinet according to claim 1 wherein said bottom panel further comprises two top panels oppositely positioned and welded together.
Claim 4
Dependent Claim
21 words
The metal file cabinet according to claim 1 wherein said side panels include equidistantly placed holes whereby hardware may be attached.
Claim 5
Dependent Claim
40 words
The file cabinet according to claim 3 wherein said equidistantly placed holes of said side panels are symmetrically arranged about a vertical centerline along said troughs thereby being symmetrically opposed between each side panel when said box-like structure is constructed.
Claim 6
Dependent Claim
31 words
The file cabinet according to claim 4 wherein said outer wrapper is attached to said side panels by adhesive, said being placed on one of said ridges of said side panels.
Claim 7
Dependent Claim
64 words
The file cabinet according to claim 5 wherein said outer wrapper includes top and bottom ledges, said top and bottom ledges of said outer wrapper being further attached to said side panels by spot welds located at the upper and lower portions of said side panels where said side panels complementarily mate with said top and bottom panels to form said box-shaped inner framework.
Claim 8
Dependent Claim
30 words
The file cabinet according to claim 6 wherein a top pan is placed over said top panel and said top ledge of said outer wrapper to conceal said spot welds.
Claim 9
Dependent Claim
32 words
The file cabinet according to claim 7 wherein a base pan is placed underneath and around said bottom panel and said bottom ledge of said outer wrapper to conceal said spot welds.
Claim 10
Dependent Claim
112 words
A file cabinet comprising: a set of two vertically disposed side panels extending substantially the depth of said cabinet; a horizontally disposed top panel extending substantially the depth of said cabinet and attached at its ends to the top ends of each of said side panels; a horizontally disposed bottom panel extending substantially the depth of said cabinet and attached at its ends to the bottom ends of each of said side panels; each of said panels having substantially the same cross-sectional configuration, with each of said panels having a plurality of corrugations therein for strengthening said cabinet; and a substantially one-piece metal outer wrapper which covers at least three vertical sides.
Claim 11
Dependent Claim
112 words
A file cabinet comprising: a set of two vertically disposed side panels extending substantially the depth of said cabinet; a horizontally disposed top panel extending substantially the depth of said cabinet and attached at its ends to the top ends of each of said side panels; a horizontally disposed bottom panel extending substantially the depth of said cabinet and attached at its ends to the bottom ends of each of said side panels; each of said panels having substantially the same cross-sectional configuration, with each of said panels having a plurality of corrugations therein for strengthening said cabinet; and a substantially one-piece metal outer wrapper which covers at least three vertical sides.
Claim 12
Dependent Claim
26 words
The file cabinet according to claim 9 wherein said top panel and said bottom panel are welded to said side panels to form a box-like structure.
Claim 13
Dependent Claim
31 words
The metal cabinet according to claim 9 wherein said panels include ridges and troughs, said ridges located near the outer edge of each panel and said troughs located between said ridges.
