  • embodiments of the present invention provide an actuator 26 that includes a uniform cross section along at least a portion of its length. For example, FIG.
  • the actuator 26 may include a rectangular cross section along at least a portion of the actuator that extends outwardly from the drawer 15 in the locked state.
  • a portion of the lock 12 extending outwardly from the drawer 15 may include all vertical surfaces or surfaces that are parallel to one another.
  • at least a portion of the actuator 25 may be straight or not curved or rounded.
  • a free end of the actuator 26 may include a curved or rounded portion that facilitates engagement with the strike plate 36 when moving the merchandise fixture 13 towards a locked state.
  • the portion of the actuator 26 that extends between the bottom surface of the strike plate 36 and the top surface of the drawer 15 is not curved (see, e.g., FIGS.
  • FIG. 1 shows an embodiment of a merchandise fixture 13 including a movable drawer 15 and a fixed support structure 16.
  • the electronic lock 12 may be configured to be mounted to the drawer 15, while the strike plate 36 is configured to be mounted to the support structure 16.
  • the electronic lock 12 may be fixed, while the strike plate 36 is configured to be mounted to a movable structure.
  • FIG. 16 shows an instance where the electronic lock 12 is mounted to a stationary structure 16' , while the strike plate 36 is mounted to a pivoting drawer 15' or the like.
  • FIGS. 1 and 16 show that the orientation of the electronic lock 12 remains the same whether mounted to a movable drawer 15' (e.g., FIG. 1) or mounted to a stationary structure 16' (e.g., FIG. 16).
  • the lock 12 is capable of being secured to the merchandise fixture 13 in one of two different and opposite orientations without affecting the functionality of the lock.
  • embodiments of the present invention may provide several advantages.
  • the outer surface of the merchandise fixture may be completely free of the electronic lock.
  • the merchandise security device is completely hidden from view.
  • This arrangement not only provides a "clean" look but also does not provide any conspicuous way for a thief to attack the electronic lock.
  • a sales associate is not required to lock the electronic lock after being unlocked since the lock mechanism is configured to self lock automatically.
  • the drawer is able to be closed while the lock mechanism is in a locked state such that the electronic lock does not need to communicate with the electronic device in order to close the drawer.
  • the electronic lock cannot be left in an unlocked state, even after communicating with an electronic device and while the drawer remains closed, since the lock mechanism self locks after a predetermined period of time.
  • the electronic lock allows for automatic relocking even when the electronic device is no longer in communication therewith.
  • the electronic lock includes "anti-picking" features that resist defeating the lock while in a locked state.
  • the electronic lock also allows for use with different types of merchandise fixtures, and may be mounted to stationary or movable merchandise fixtures or components thereof.
