Abstract

There is described a rectangular shaped security cabinet having a door opening which is closed by a tambour door. The door is made from a plurality of interlocking slats capable of limited flexure relative to one another, the slats having interlocking hooked tongues on the upper faces which lockingly engage with slots on the lower faces. A protection barrier extends from the top face behind the hooked tongue and inhibits access to the joint formed by the hooked tongue and the receiving slots. Additionally the door is provided with a lock operated by a combination lock which lock includes a sliding bar at the back of the door which engages with upstanding projections on the door bottom sill. A cam like latch, biased to the open position is operable by the combination lock to engage in a catch on the sliding bar to lock the bar and thus the door, in the locked position. Further, there is described a secure rear panel in which the rivets which lock the panel to the back of the cabinet housing are not accessible from the outside. Finally, there are described various elements for providing a tortuous path for electrical wiring entering into the cabinet to inhibit access to the cabinet along the wiring paths.
