发明名称 Videocassette security-lock-box
摘要 A videocassette security box includes a base with a protective cover pivotally attached thereto and adapted to contain videocassettes. A key-hole orifice through the base allows mounting of the base over a doorknob or other suitable mounting member whereafter the narrower portion of the key-hole is moved behind the doorknob. Closing of the cover blocks across to the larger portion of the key-hole to preclude removal of the box from the doorknob as long as the cover remains closed while a lock mechanism allows securing of the cover in the closed position.
