Embodiment Construction

[0050] Traditional three-ball clutch assemblies for security tags rely on magnetic force to release the system's locking mechanism. This requires that most or all of the parts within the three-ball clutch be made of ferromagnetic materials. These materials tend to be heavy and expensive relative to their polymeric counterparts. Another disadvantage of security tags that use magnetic force to release the tag's locking mechanism is that it may fail if the tag is subjected to a magnetic field of sufficient strength. The disclosed electronic security tags, also known as electronic article surveillance (EAS) tags or loss prevention (LP) tags, include a non-magnetic three-ball clutch that can be generally applied to any tag architecture, regardless of retraction to release mechanism (e.g., How about vertical magnetic lever arms, electric motors or linear solenoids, shape memory alloy (SMA) actuators, etc.) approaches.

Abstract

An example electronic security tag attachable to an item includes a tag body member, a connection member having a pin portion releasably engageable with the tag body member, the pin portion extending along a first axis. The electronic security tag further comprises a locking component to lock the connecting component to the tag body component. The locking member includes a clutch mechanism movable along a second axis parallel to the first axis between a first position in contact with the pin portion and corresponding to a locked state and a second position corresponding to an unlocked state. The clutch mechanism includes at least one component formed of a non-ferromagnetic material.

Description

[0001] Related applications [0002] This application claims priority to and benefit from U.S. Provisional Patent Application Nos. 62 / 871,646, 62 / 871,650, 62 / 871,652, and 62 / 871,656, all filed on July 8, 2019, The entire content of each of the foregoing applications is hereby incorporated by reference for all purposes as if fully set forth in this document. technical field [0003] Aspects of the present disclosure are directed to security tags for attaching to items, and more particularly, to electronic security tags having a body for housing one or more sensors, with mating pushpin pins for attaching to thing. [0004] Additionally, aspects of the present disclosure generally relate to electronic security tags for use in electronic article surveillance ("EAS") systems for preventing unauthorized removal of items from a given location (eg, a retail store). More specifically, the present disclosure relates to an improved security tag, and a novel non-magnetic method and app...
