Abstract
A cabinet in which the closure or door thereof is rendered less vulnerable to unauthorized tampering which seeks to bypass the lock thereof as a result of the door being latched behind an edge of the cabinet front opening. Thus, opening of the door contemplates a compound movement, i.e. an initial unlatching sliding movement, and then the usual pivotal traverse from its closed into its open position. As a significant improvement, the construction of the within cabinet effectively masks the presence of the structural features which contribute to the door compound movement, whereas this is not the case with prior art cabinet doors and, as a result, such omission in an obvious way, detracts from the effectiveness of the security intended to be gained by the compound door movement.
Claims5
An improved tamper-proof cabinet comprising a cooperating arrangement of upper, lower and opposite side walls bounding a storage compartment for said cabinet having a first rectangular opening thereinto, a frame bounding an inner second rectangular opening of a selected smaller size than said first opening and of a selected external size larger than said cabinet disposed in surroundng relation about said first opening so that said frame presents a surface extending in overhanging relation along at least one vertically oriented side of said first opening, a cabinet door member having vertically oriented pivot pins extending in opposite directions therefrom operatively mounted for pivotal opening and closing movements relative to said second opening and sized slightly larger in its horizontal dimension than said second opening so that in said closed position thereof an edge thereon is in latched relation behind said vertically oriented overhanging surface of said frame, and spring means connected in spanning relation between said cabinet housing walls and said pivot pins in positions masked from view behind cooperating upper and lower horizontally oriented overhanging surfaces of said frame, whereby said door pivotal opening movement is required to be preceded by an unlatching door sliding movement in the plane of said second opening as permitted by the expansion of said spring means wherein each said upper and lower cabinet wall is recessed to accommodate a cooperating one of said spring means and thereby present a rectangular shaped profile, whereby said cabinet is adapted to be mounted in an opening of a support wall having a corresponding rectangular shape.
An improved tamper-proof cabinet comprising housing walls cooperating to define a storage compartment and having edges thereon bounding a front access opening into said compartment, a pair of tamper-preventing surfaces extending from said front opening upper and lower horizontally oriented edges respectively bent substantially perpendicularly of said front opening, a pair of framing members connected along the remaining spaced apart vertical edges of said front opening to as to respectively present an additional tamper-preventing surface in overhanging relation to one said edge and a latching surface similarly in overhanging relation to said other edge, a cabinet door member having vertically oriented pivot pins extending in opposite directions therefrom operatively mounted for pivotal opening and closing movements relative to said front opening along a vertical axis located behind said additional tamper-preventing surface and sized so that in said closed position thereof an edge thereon is in latched relation behind said latching surface, and spring means connected in spanning relation between said housing walls and said pivot pins behind said upper and lower tamper-preventing surfaces, whereby said door pivotal opening movement is required to be preceded by an unlatching door sliding movement in the plane of said front opening as permitted by the expansion of said spring means wherein those of said housing walls defining the upper and lower portions of said storage compartment are each recessed to accommodate a cooperating one of said spring means and thereby present a rectangular shaped profile, whereby said cabinet is adapted to be mounted in an opening of a support wall having a corresponding rectangular shape.
