Abstract
Systems (100) and methods (1000) for operating a Security Tag (“ST”). The methods involve rotating a Rotational Clip (“RC”) of ST (132) towards a Housing Base (“HB”) of ST until RC (406) contacts a latch (610) disposed within HB (404), where an article resides between a first pad (602) fixedly coupled to RC and a second pad (604) movably coupled to HB. An angled surface (626) of RC slides against an angled surface (624) of the latch so as to cause compression of a cap spring (614) and a latch spring (612). The cap spring is disposed in HB such that a center axis (818) thereof is perpendicular to a center axis (816) of the latch spring. When the latch becomes aligned with an aperture (628) formed in the rotational clip, the latch travels into the aperture as result from a pushing force applied thereto by the latch spring.
Claims20
A method for operating a security tag, comprising:
- rotating a rotational clip of the security tag towards a housing base of the security tag until the rotational clip contacts a latch disposed within the housing base, where at least a portion of an article resides between the rotational clip and the housing base;
- sliding an angled surface of the rotational clip against an angled surface of the latch so as to cause simultaneous compression of a cap spring and a latch spring, where the cap spring is disposed in the housing base such that a center axis thereof is perpendicular to a center axis of the latch spring;
- aligning an engagement structure of the latch with an aperture formed in the rotational clip;
- and
- applying a pushing force by the latch spring to the latch such that the engagement structure travels into the aperture formed in the rotational clip.
A security tag, comprising:
- a housing base having a latch and a cap spring disposed therein;
- a rotational clip rotatively coupled to the housing base, where the latch engages the rotational clip when the rotational clip is rotated towards the housing base;
- and
- a cap movably coupled to the housing base so as to be resiliently biased in a direction away from the housing base by the cap spring, where the cap spring is further compressed when the security tag is affixed to an article at least partially disposed between the cap and the rotational clip.
