Abstract

Abstract In combination with the computer of other electrical appliance having a base which is mountable upon a support having an undersurface, there is provided a security platform for anchoring and locking the computer to the support. The security platform comprises a pair of spaced platform bars bearing against the base, each bar having a first pair of apertures therethrough with fasteners projecting up therethrough, and threaded into the base for securing the bars to the base. Each bar has a second pair of apertures for receiving a pair of bolts which extend downwardly therethrough and through corresponding bores in the support. Fasteners are threaded onto the bolts in snug retaining registry with the support. Spaced apertured detent plates underlie each anchor bar with one aperture receiving a bolt. A lock assembly bears against each detent plate protectively encloses the adjacent fastener and includes a key operated cylinder lock having a cam retainer for projection through the retainer plate and secured thereto. The bolts may be integral with the platform bar.
