Abstract

An electronic article surveillance apparatus for monitoring large objects is comprised of a base, at least one segment of tape, and an electronics housing. The segment of tape has a least one electrically conductive element running the length of the tape. The base rests on an object to be monitored, and the housing releasably latches onto the base, while each tape segment wraps around the object with each end of tape segment being fixed between the base and housing. Electronics within the housing complete a circuit through each tape segment and monitor the tape segments for electrical continuity. If electrical continuity is lost, either by cutting a tape segment, or unauthorized unlatching of the housing, an alarm can be sounded by the electronics within the housing. The electronic housing may be disarmed by a remote device and delatched from the base. Both base and tape segments may have adhesive elements.

said electronic components in said housing portion completing electrical continuity within each set of electrical contacts;

said at least one side having a receptacle for each said hinging hook in said base portion,

said at least one releasable latch being positioned to releasably engage said at least one latch receiver when said at least one latch receiver is inserted into a latch pocket.

2. The electronic article surveillance apparatus of claim 1, wherein:

said bottom surface of said base portion has an adhesive element on said bottom side.

3. The electronic article surveillance apparatus of claim 1, wherein:

said at least one releasable latch is releasably lockable.

4. The electronic article surveillance apparatus of claim 1, wherein:

said at least one releasably lockable latch is unlocked by application of a magnet.

5. The electronic article surveillance apparatus of claim 1, wherein:

said at least one releasable latch requires manual operation to engage said releasable latch to said at least one latch receiver.

6. The electronic article surveillance apparatus of claim 5, wherein:

said at least one releasable latch may be manually slid to engage said at least one latch receiver;

said electronic surveillance apparatus further comprising a biased blocking component, said biased blocking component moving to a blocking position when said at least one releasable latch is manually slid to engage said at least one latch receiver, thereby blocking the return of said at least one releasable latch;

said biased blocking component being movable to a non-blocking position by application of a magnet to a magnetically attractable element associated with said biased blocking component, the shifting of said biased blocking component to a non-blocking position allowing said at least one releasable latch to be manually shifted to disengage said at least one latch receiver.

7. The electronic article surveillance apparatus of claim 1, wherein:
