Abstract

Abstract The cupboard is made from a framework comprising four tubular uprights having a square section and two rectangular or square frames. The sides of the frames are tubes having the same square section as the uprights. In the corners of each frame, the adjacent tubular members are assembled by means of oblique welded gussets. The latter permit the assembly with the uprights engaged in recesses of the frames by means of screws. The side panels are locked to the framework by a roof-cover which has folded edge portions which overlap the upper end of the panels.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 271 words
In a metal cupboard comprising a parallel-sided framework, the framework comprising an upper frame having a rectangular shape and comprising tubular members, a lower frame having a rectangular shape and comprising tubular members, four uprights constituted by tubular section members which are assembled at respective ends thereof with the upper and lower frames, at least two rectangular panels respectively closing at least two lateral sides of the framework, which sides are in opposed relation, and a sheet metal roof covering said upper frame; the improvement comprising an arrangement which is sufficient to maintain said at least two panels assembled with the framework and with the roof and comprises in combination first flange means rigid with a lower end portion of each of said at least two panels and downwardly bearing on a corresponding one of said tubular members of said lower frame, second flange means rigid with an upper end portion of each of said at least two panels and downwardly bearing on a corresponding one of said tubular members of said upper frame, and downwardly extending edge portions on said roof so that said roof constitutes a lid which closely caps said at least two panels and said downwardly extending edge portions overlap and engage said upper end portions of said at least two panels and trap said upper end portions between said downwardly extending edge portions and said corresponding ones of said tubular members of said upper frame and said roof overlaps and engages said second flange means and traps said second flange means between said roof and said corresponding ones of said tubular members of said upper frame.
Claim 2
Dependent Claim 271 words
In a metal cupboard comprising a parallel-sided framework, the framework comprising an upper frame having a rectangular shape and comprising tubular members, a lower frame having a rectangular shape and comprising tubular members, four uprights constituted by tubular section members which are assembled at respective ends thereof with the upper and lower frames, at least two rectangular panels respectively closing at least two lateral sides of the framework, which sides are in opposed relation, and a sheet metal roof covering said upper frame; the improvement comprising an arrangement which is sufficient to maintain said at least two panels assembled with the framework and with the roof and comprises in combination first flange means rigid with a lower end portion of each of said at least two panels and downwardly bearing on a corresponding one of said tubular members of said lower frame, second flange means rigid with an upper end portion of each of said at least two panels and downwardly bearing on a corresponding one of said tubular members of said upper frame, and downwardly extending edge portions on said roof so that said roof constitutes a lid which closely caps said at least two panels and said downwardly extending edge portions overlap and engage said upper end portions of said at least two panels and trap said upper end portions between said downwardly extending edge portions and said corresponding ones of said tubular members of said upper frame and said roof overlaps and engages said second flange means and traps said second flange means between said roof and said corresponding ones of said tubular members of said upper frame.
Claim 3
Dependent Claim 61 words
A cupboard as claimed in claim 1, wherein the tubular section members of the framework and the tubular members of the frames have a square-crosssectional shape and said second flange means is a flange which is at right angle with the corresponding panel and is disposed flat against the corresponding tubular member of said upper frame and flat against the roof.
Claim 4
Dependent Claim 265 words
A cupboard as claim in claim 1 or 2, comprising means defining a door opening between said two lateral sides of the framework, two displaceable side-by-side door elements respectively having edges forming a joint line intermediate said two lateral sides of the framework when the door elements are in a closing position in a plane, each door element being pivotally mounted on the framework at an upper and a lower end thereof by means comprising a link which is pivotally connected to the door element adjacent a first end of the link and pivotally connected to the cupboard adjacent a second end opposed to said first end of the link, said pivotal connections having pivot axes parallel to said plane, the link being pivotable outwardly of the cupboard when initiating a displacement of the corresponding door element from said closed position thereof for opening said door opening, said first end of the link being adjacent said edge of the corresponding door element and said second end of the link being remote from said edge in a closing position of the door elements, means being provided for guiding each door element and comprising a rail which is mounted on the framework and extends inwardly of the cupboard from said door opening and defines with a corresponding one of said at least two panels an inwardly tapering passageway for receiving an edge of the door element remote from said edge thereof when opening the door opening, the rail and links constraining the door element to move back into the interior of the cupboard alongside the corresponding panel.
Claim 5
Dependent Claim 77 words
A cupboard as claimed in claim 1 or 2, wherein the second flange means of each of said at least two panels is constituted by a horizontal flange of an L-section member which has a vertical flange which is welded to an inner face of the panel and is inwardly offset relative to the panel and constitutes said upper edge portion of the panel and defines a recess receiving the downwardly extending edge portions of the roof.
