Electronic article surveillance tag
View Patent ↗An embodiment is an EAS tag that may be included in an EAS system. More specifically, an embodiment is an EAS tag including an arcuate channel and additional features to hinder the removal of the EAS tag with devices other than those specifically designed for such a purpose.
1. An electronic article surveillance (EAS) tag comprising:
a body;
a rotary clamp coupled to the body to clamp a pin of a removable tack to detachably engage the EAS tag to an object; and
an arcuate channel disposed in the body, one end of said arcuate channel opening at a side surface of the body, an opposite end of said arcuate channel disposed adjacent to the rotary clamp, the arcuate channel to include a keyway formed in a portion of the arcuate channel,
wherein the keyway comprises an “L” shaped keyway to allow the insertion of a hook into the arcuate channel to operate the rotary clamp, the “L” shaped keyway further to substantially prevent the insertion of a fish tape into the arcuate channel to operate the rotary clamp;
wherein the arcuate channel has a length as measured between the ends of the arcuate channel, the “L” shaped keyway further including a vertical leg and a horizontal leg'the horizontal leg and the vertical leg of the “L” shaped keyway to be located at different distances along the length of the arcuate channel.
2. The EAS tag of claim 1 , the horizontal leg and the vertical leg each having a width relative to an intersection of the horizontal leg and the vertical leg of approximately between 0.028 and 0.032 inches and a height relative to the intersection of the horizontal leg and the vertical leg of approximately between 0.094 and 0.096 inches.
3. The EAS tag of claim 2 , the arcuate channel to include a widened portion disposed farther away from the side surface of the body than the “L” shaped keyway.
4. The EAS tag of claim 2 , further comprising an obstacle positioned within the body adjacent to a second radius of the arcuate channel, the obstacle located at a point along the length of the arcuate channel that is farther from the side surface than that of said “L” shaped keyway, the obstacle to engage the fish tape to prevent movement of the fish tape along the arcuate channel.
5. An electronic article surveillance (EAS) tag comprising:
a body;
a rotary clamp within the body; and
an arcuate channel disposed in the body, one end of said arcuate channel opening at a side surface of the body, an opposite end of said arcuate channel disposed adjacent to the rotary clamp, the arcuate channel to include an “L” shaped keyway, the body further including an obstacle positioned adjacent to a second radius of the arcuate channel at a point along a length of the arcuate channel that is farther from the side surface than that of the keyway to substantially prevent a formed fish tape including a kink bend from engaging the rotary clamp;
wherein the “L” shaped keyway further including a vertical leg and a horizontal leg, the horizontal leg and the vertical leg of the “L” shaped keyway to be located at different distances along the length of the arcuate channel.
6. The EAS tag of claim 5 , the horizontal leg and the vertical leg each having a width relative to an intersection of the horizontal leg and the vertical leg of approximately between 0.028 and 0.032 inches and a height relative to the intersection of the horizontal leg and the vertical leg of approximately between 0.094 and 0.096 inches.
7. The EAS tag of claim 5 , the arcuate channel to include a widened portion disposed farther away from the side surface of the body than the keyway to substantially prevent a formed fish tape from engaging the rotary clamp.
8. An electronic article surveillance (EAS) system comprising:
an EAS tag attachable to an article, the EAS tag including a body, a rotary clamp within the body, and an arcuate channel disposed in the body, one end of said arcuate channel opening at a side surface of the body, an opposite end of said arcuate channel disposed adjacent to the rotary clamp, the arcuate channel to include an “L” shaped keyway, the “L” shaped keyway including a vertical leg and a horizontal leg, the horizontal leg and the vertical leg of the “L” shaped keyway to be located at different distances along a length of the arcuate channel;
an obstacle disposed within the body and positioned adjacent to a second radius of the arcuate channel at a point along the length of the arcuate channel that is farther from the side surface than that of the keyway to substantially prevent a formed fish tape including a kink bend from engaging the rotary clamp;
a detectable EAS sensor disposed in the EAS tag body;
a transmitter to transmit a first signal into a surveillance zone; and
a receiver to receive a second signal resulting from the interaction of the first signal with the detectable EAS sensor to detect the presence of the detectable EAS sensor in the surveillance zone.
9. The EAS system of claim 8 , the horizontal leg and the vertical leg each having a width relative to an intersection of the horizontal leg and the vertical leg of approximately between 0.028 and 0.032 inches and a height relative to the intersection of the horizontal leg and the vertical leg of approximately between 0.094 and 0.096 inches.
10. The EAS system of claim 8 , the arcuate channel to include a widened portion disposed farther away from the side surface of the body than the keyway to substantially prevent a formed fish tape from engaging the rotary clamp.
