Abstract

Abstract A storage cabinet adapted for mounting on a wall having side panels, a bottom panel, a top wall, and door. Keyhole slots extend through edge portions of the bottom panel. A conventional screw and non-removable stud extend through each slot, with the studs being non-removably secured to the side panel. The screws engage the front portions of the keyhole slots and the studs engage the back portions of the keyhole slots. A cover is removably secured to the back inside portion of the side panel so that the back edge of the bottom panel is in abutting engagement with the cover.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 113 words
A storage cabinet adapted for mounting on a wall and including side panels, a top panel, a bottom panel, a back panel, and a door for closing an opening between said top panel, bottom panel, and side panels, all of said panels and door being joined together to define an enclosed space, said bottom panel is removably joined to said side panels through exposed fasteners outside said enclosed space and extending through said bottom panel and side panels, the improvement which comprises: a slot in one of said bottom panel and side panels for retaining said exposed fasteners when said bottom panel is in a forward position with respect to said side panels;
Claim 2
Dependent Claim 113 words
A storage cabinet adapted for mounting on a wall and including side panels, a top panel, a bottom panel, a back panel, and a door for closing an opening between said top panel, bottom panel, and side panels, all of said panels and door being joined together to define an enclosed space, said bottom panel is removably joined to said side panels through exposed fasteners outside said enclosed space and extending through said bottom panel and side panels, the improvement which comprises: a slot in one of said bottom panel and side panels for retaining said exposed fasteners when said bottom panel is in a forward position with respect to said side panels;
Claim 3
Dependent Claim 229 words
one of said exposed fasteners mounted in an end portion of said slot to prevent forward movement of said bottom panel with respect to said side panel, said one fastener being secured to the other of said bottom panel and side panels in a non-removable fashion by which said one exposed fastener cannot ordinarily be removed without evident damage to said other of said bottom panel and side panels; means including said back wall to prevent movement of said bottom panel from said forward position to said rearward position when said cabinet is assembled; whereby said bottom panel can be removed from said side panels in the absence of said back panel by sliding said bottom panel rearwardly with respect to said side panels when all said fasteners except said one non-removable fasteners are removed; and means to secure said back panel to said side panels, said securing means being inaccessible when said cabinet is mounted to said wall and being accessible for removing said back wall from said side panels when said cabinet is removed from said wall; whereby said bottom panel cannot be removed from said side panels while said cabinet is mounted to said wall without evident damage to the other of said bottom panel and side panels, thus preventing disassembly of said cabinet when said door is locked in said opening without evidence of tampering.
Claim 4
Dependent Claim 229 words
one of said exposed fasteners mounted in an end portion of said slot to prevent forward movement of said bottom panel with respect to said side panel, said one fastener being secured to the other of said bottom panel and side panels in a non-removable fashion by which said one exposed fastener cannot ordinarily be removed without evident damage to said other of said bottom panel and side panels; means including said back wall to prevent movement of said bottom panel from said forward position to said rearward position when said cabinet is assembled; whereby said bottom panel can be removed from said side panels in the absence of said back panel by sliding said bottom panel rearwardly with respect to said side panels when all said fasteners except said one non-removable fasteners are removed; and means to secure said back panel to said side panels, said securing means being inaccessible when said cabinet is mounted to said wall and being accessible for removing said back wall from said side panels when said cabinet is removed from said wall; whereby said bottom panel cannot be removed from said side panels while said cabinet is mounted to said wall without evident damage to the other of said bottom panel and side panels, thus preventing disassembly of said cabinet when said door is locked in said opening without evidence of tampering.
Claim 5
Dependent Claim 21 words
A storage cabinet according to claim 1 and further comprising means to selectively prevent removal of said cabinet from said wall.
Claim 6
Dependent Claim 26 words
