  • Portable security case
    Patent number: 5531082
    Abstract: A portable security case (10) includes a base (12) and a lid (14). A cable lock (32) locks both the lid (14) to the base (12) and the base (12) to another object (59). A spring catch (66) and dead bolts (82) also lock the lid (14) to the base (12). A spring latch (68) prevents the spring catch (66) from unlocking when the cable lock (32) is locked. A cable (40) is captured in different positions within the base (12) for adjusting its length, and hinges (91 and 93) are mounted in interior side walls (28 and 30) of the base (12) to provide an uninterrupted parting line between the base (12) and the lid (14).
