Abstract
An anti-theft device for securing merchandise against theft. The anti-theft device has a stand that mounts onto a display surface. A pair of arms is disposed in a linear sliding relationship relative to the stand. The arms terminate with inwardly facing grips that receive the opposing edges or corners of the merchandise. The arms have gear racks operatively engaged by a pinion gear. The pinion gear is joined to a concentrically aligned worm wheel, which is operatively engaged by a worm. A motor is configured to selectively spin the worm in the first or the second direction, thereby selectively retracting or extending the arms relative to the stand to secure or release the merchandise, respectively. The worm drive immobilizes the arms against being extended from the stand using manual force, thereby locking the merchandise to the stand. A fob may be used to transmit a signal that actuates the motor.
