Abstract

The security system generally includes an elongate tubular member provided with a row of spaced apertures and a locking member movably mounted within the tubular member and formed with a series of pockets. Elongate flexible guard members with enlarged heads at each end are passed through a closed loop portion of the article and the heads are inserted through a selected pair of adjacent apertures and into the corresponding pockets. Relative movement of the tubular member and locking member reduce the effective exit area and all heads are locked in the tubular member simultaneously. An electrical circuit is connected with an alarm device and with the various pockets. When both heads of the guard member are in a selected pair of pockets or both removed, the circuit is complete. When one head is in a pocket and the other is not, or if a cable is cut by a shoplifter, the circuit is open. The alarm device is arranged to emit a visual and/or audio warning signal when the system is in locked condition and an open circuit occurs.

an elongate tubular member provided with a plurality of longitudinally spaced apertures extending through its wall;
locking means mounted within the tubular member including a plurality of outward opening receivers spaced longitudinally to correspond with the spacing of the apertures and to lie in registry with them;
a plurality of individual elongate flexible guard members, each provided with an enlarged head at each end, adapted to be passed through a closed loop portion of an article of merchandise with the heads entering through a selected pair of apertures in the tubular member and into the corresponding registered receivers;
and
an actuating means to change the relative position of the tubular member and at least a portion of the locking means by displacing at least that portion of the locking means which includes the receivers, and positively transfering the guard member heads to off-center positions with respect to the apertures to prevent removal of the heads from the tubular member;
