Patent ID: 7918112

Claim:
A security device comprising: a housing; a first cable; a spool within the housing which is rotatable about a vertical axis in a cable-tightening direction to wind the cable thereon and rotatable in an opposite cable-loosening direction to unwind the cable therefrom; a first engaging member within the housing; a second engaging member within the housing; wherein the first engaging member is rotatable with the spool relative to the housing and second engaging member about the vertical axis and is movable upwardly and downwardly relative to the spool and second engaging member between a locked position in which the first engaging member engages the second engaging member to prevent rotation of the spool in the cable-loosening direction and an unlocked position in which the first engaging member is disengaged from the second engaging member to allow rotation of the spool in the cable-loosening direction; and an automatic return which is initiated by rotation of the spool in the cable-tightening direction to automatically return the first engaging member from the unlocked position to the locked position.
