Tamper-proof noose sensor
A security device including a base having a plurality of holes extending therethrough. A noose cable is attached to the base and extends out of the base on one side and passes through the base on another and may be wrapped around merchandise to be secured against theft. A switch is carried by the base and depressed by a lid carried by the base so that when the lid is raised, an alarm will sound. A fastener extends through the lid of the base and secures the noose cable from removable such that when the lid is in the closed position, the head of the fastener is beneath the lid and access to the fastener is prevented. The base is electrically connected to an alarming station in order to provide power to the switch and to provide the alarming function associated with the noose cable security device.
1. A security device comprising:
a base formed with first and second apertures;
a lid mounted on the base movable between open and closed positions;
a switch located within the base which is activated when the lid is moved from one of the open and closed positions to the other of the open and closed positions and which will sound an alarm when the switch is tripped;
a noose cable having first and second ends, said first end being relatively fixed to the base, said second end sized to pass through the first and second apertures formed in the base to form an adjustable loop for placement about an object to be protected by the security device; and
a fastener located within an access area of the base to permit adjustment of the size of the loop and forming an adjustable space adjacent the fastener and below the lid through which the cable passes to trap the cable in the base upon rotation of the fastener, said fastener having a head positioned below the lid when the lid is in the closed position.
2. The security device as defined in claim 1 wherein a follower operatively engages the fastener and forms the adjustable space for trapping the cable in the base upon rotation of the fastener.
3. The security device as defined in claim 2 wherein a terminator is mounted on the second end of the cable, said terminator having a diameter larger than the diameter of the cable but sized to pass through the first and second apertures; and in which the space adjacent the follower can be sized upon rotation of the fastener to permit free movement of the cable therethrough while preventing movement of the terminator through said space.
4. The security device as defined in claim 1 further comprising an activation button connected to the switch in operational contact with the lid when the lid is in the closed position.
5. The security device as defined in claim 4 in which the lid is hingedly mounted on the base at one end.
6. The security device as defined in claim 5 further comprising a catch formed on the lid, and a mating recess formed in base such that the catch engages the recess when the lid is in the closed position.
7. The security device as defined in claim 6 in which the lid includes a perimeter wall extending toward the base.
8. The security device as defined in claim 4 further comprising an alarm electronically connected to the switch such that when the switch is tripped, the alarm will sound.
9. The security device as defined in claim 8 further comprising a top wall formed on the base, and which the activation button extends adjacent the top wall, and in which the lid will depress the actuation button when in the closed position.
10. The security device as defined in claim 9 in which the switch is carried by the base below the top wall and in which the activation button extends through the top wall.
11. The security device as defined in claim 10 in which the fastener is a screw, and in which the screw extends through the top wall and threadably engages the follower, and in which the noose cable extends through the first and second apertures of the base below the top wall.
12. The security device as defined in claim 1 in which the screw head is a torque type head.
13. The security device as defined in claim 1 further comprising:
an alarming station; and
an alarming cable extending from the alarming station to the base and in which the alarming cable is electrically connected to the switch such that when the switch is tripped, the alarm will sound.
14. The security device as defined in claim 13 in which the alarming cable is electrically connected to the noose cable whereby when the noose cable is cut, the alarm will sound.
15. The security device as defined in claim 14 in which the switch is electrically connected to the noose.
16. The security device as defined in claim 15 further comprising a light bulb electrically connected to the alarming cable whereby the light remains illuminated when the lid is in the closed position.
