Abstract (en)
[origin: EP0410122A1] Mortise lock with a catch bolt (5) which can be retracted as a result of either pusher key actuation via a change mechanism, and a fixing element which is accessible and actuable from the lock face plate and which makes it possible to detain the catch bolt (5) in the retracted state counter to the effect of a catch-bolt spring (6) engaging on it. To provide a mortise lock with catch-bolt fixing of the generic type mentioned in the introduction, which does not have the aforesaid disadvantages, but on the contrary allows the catch bolt (5) to be fixed only by the authorised keyholder, but for which no additional lock cylinder to be arranged, for example, in the lock face plate is to be used, but instead the key insertion orifice present in any case in the mortise lock, usually in its built-in lock cylinder, is to be used for this purpose, it is so designed that the catch bolt (5) can be retracted by the key-actuable change mechanism (16, 17) by an excess amount further than as a result of its actuation by the pusher, and in the corresponding range of excess movement of the catch bolt (5) and of the change mechanism (17) the fixing element (21) is to be brought into detaining engagement with the latter. <IMAGE>
