1. A panic lock for building into a door or similar, either as a left lock or a right lock, comprising:
a lock case; a dead bolt and a turnable panic plate to operate the dead bolt; a latch bolt and a turnable finger plate to operate the latch bolt, whereby the latch bolt can be turned through 180° in a holder between two positions corresponding to an intended installation as a left or right lock respectively; two handle followers which are mounted in the lock case in a way that they can turn coaxially with respect to one another and which each separately, depending on the intended installation as a left or right lock, can act as an inside or outside handle follower, wherein a selectively switchable coupling is provided with two positions that enables, depending on the selected position of the coupling, the one or the other handle follower to be turnably coupled to the finger plate and the panic plate, and the other handle follower to be uncoupled in order to let it freely turn with respect to the finger plate and to the panic plate, whereby a switching mechanism is provided between the latch bolt and the switchable coupling that is such that, when the latch bolt is turned from the one to the other of the two positions of the latch bolt, the position of the coupling is switched from the one to the other position in order to couple the one or the other handle follower to the finger plate and the panic plate, wherein the switchable coupling is provided with a coupling element that is held so that it can move in the radial direction in a guide of the panic plate and which extends up to a recess of each of the handle followers. |
