Abstract
A security system including a security tag is provided. The security tag includes a housing and a pin in which the pin is removably insertable into the housing. The security tag further includes a latching element disposed within the housing and positionable in a lock position and in an unlock position. The latching element includes a pivot axis. The latching element has a substantially balanced rotational response about the pivot axis when exposed to an external physical mechanical impulse. The security tag further includes a bias element that releasably positions the latching element in the lock position. The latching element releasably engages the inserted pin when in the lock position.
Claims21
A security tag, comprising:
- a housing;
- a latching element disposed within the housing and positionable in a lock position and in an unlock position, the latching element including a pivot axis, the latching element having a substantially balanced rotational response about the pivot axis when exposed to an external physical mechanical impulse;
- and
- a bias element, the bias element releasably positioning the latching element in the lock position.
A security system, comprising:
- a security tag, the security tag device including:
- a housing;
- a pin, the pin being removably insertable into the housing;
- a latching element being disposed within the housing and positionable in a lock position and in an unlock position, the latching element including a pivot axis, the latching element having a substantially balanced rotational response about the pivot axis when exposed to an external physical mechanical impulse;
- and
- a bias element, the bias element releasably positioning the latching element in the lock position, the latching element releasably engaging the inserted pin when in the lock position.
A latching element for use in a security tag, the latching element comprising:
- a center of gravity;
- a pivot axis, the pivot axis being disposed substantially near the center of gravity;
- a plurality of pivot tabs disposed along the axis, the plurality of pivots tabs being rotatable about the pivot axis;
- and
- the latching element including a first end and second end distal the first end, the first end having a similar magneto-mechanical rotational response as the second end when the latching element is exposed to the magnetic field.
A security system, comprising:
- a security tag, the security tag device including:
- a housing;
- a pin, the pin being removably insertable into the housing;
- a first latching element being disposed within the housing and positionable in a first lock position and in a first unlock position;
- a first bias element, the first bias element releasably positioning the first latching element in the first lock position, the first latching element releasably engaging the inserted pin when in the first lock position;
- a second latching element disposed within the housing and positionable in a second lock position and in a second unlock position;
- a second bias element, the second bias element releasably positioning the second latching element in the second lock position, the second latching element releasably engaging the inserted pin when in the second lock position;
- and
- at least one of the first latching element and second latching element are substantially balanced, a pivot axis and a center of gravity of the at least one of the first latching element and second latching element being within a distance of up to approximately twenty percent of a length of the at least one substantially balanced latching element from each other.
