Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A security enclosure containing a microcomputer apperatus having externally connected cables and internally removable accessories comprising base assemply means of wirework construction attachable to a work area receiving said microcomputer apparatus, upper assembly means of wirework construction pivotally mounted on said base assembly means between a closed position fully enclosing said microcomputer apparatus and an open position permitting removal of said apparratus and any of the accessories thereof, and means for locking said pivotally mounted assembly means in its closed position against said base assembly means, the wirework construction of both said assembly means including guard means to prevent removal of cables with connectors at the ends thereof plugged into said apparatus and internal accessories of said microcomputer apparatus while at the same time exposing said apparatus effectively to full viewing and permitting normal control and operation thereof by a user, said guard means being effective only when said upper assembly means is closed and locked with said base assembly means.
