Abstract
A utility cart includes a cabinet with a latch and strike lock, which is unlocked in the presence of a passive near field RFID key device and held open by a latch controller for sufficient time to allow the user to open the unlocked cabinet door. The latch is biased to its locking position, to which it returns when released by the controller. The latch includes a ramp surface which is engaged by the leading edge of the strike as the cabinet door is closed. In this way, the strike pushes the latch out of the way as it passes over the end of the latch, and the biased latch then returns to its locking position engaging a keeper in the strike as the keeper passes into position opposite the latch.
