Abstract

A lock assembly is described which attaches to a computer or other electrical equipment to disable the power switch to prevent unauthorized use. A molded housing 10, shown in Fig. 1, is fabricated from high impact plastic and has a tab 11 which allows a hinged door to be locked only when the power switch is in the "off" position. A tab 12 is positioned to prevent horizontal movement of the lock assembly after it is attached to the computer. Tabs 13 are molded in the housing to facilitate attachment of the units between the computer cover opening and power switch housing. A skirt 14 provides coverage to the computer housing assembly screws and renders them inaccessible. Fig. 2, a front view of the housing, shows the molded door 15 and the location of the snap-action lock 16.

Computer Security Lock

A lock assembly is described which attaches to a computer or other electrical equipment to disable the power switch to prevent unauthorized use. A molded housing 10, shown in Fig. 1, is fabricated from high impact plastic and has a tab 11 which allows a hinged door to be locked only when the power switch is in the "off" position. A tab 12 is positioned to prevent horizontal movement of the lock assembly after it is attached to the computer. Tabs 13 are molded in the housing to facilitate attachment of the units between the computer cover opening and power switch housing. A skirt 14 provides coverage to the computer housing assembly screws and renders them inaccessible. Fig. 2, a front view of the housing, shows the molded door 15 and the location of the snap-action lock 16. The molded door 15 is attached to the housing 10 by means of an integral molded hinge 17. A locking tab 18, shown in Fig. 1, is positioned in the housing 10 to accommodate the pawl of lock 16 when the door 15 is in the closed position. The use of a slam-action key latch permits the unit to be locked without a key. The security lock can be attached to an IBM Personal Computer with no modifications, and to other computers or electrical equipment with modifications to the tabs, as required.
