The invention concerns a device for lifting, in particular in the event of a breakdown or failure, the ban on the opening of a conditional opening locking system. This device includes : - driving means (MT), - a transmission member (28), - a blocking member (PVI) connected to the driving means (MT) via the transmission member (28) and able to be actuated by the driving means (MT) to occupy an active position (P1) in which it opposes the movement of a bar, and an inactive position (P2) in which it authorises the movement thereof, said device being characterised in that it includes de-activation means (54, 64, 66) provided for freeing the transmission member (28) and authorising the release of the blocking member (PVI) from its active position (P1). The invention applies in particular to a conditional opening locking system and particularly to a time lock.
Cette invention concerne un dispositif qui, en cas de panne ou de bris, neutralise l'interdiction de déverrouillage d'une serrure conçue pour s'ouvrir à certaines conditions seulement. Le dispositif comprend : un moyen d'entraînement (MT), un élément de transmission (28), un élément de blocage (PVI) raccordé au moyen d'entraînement par l'élément de transmission (28) et pouvant ainsi être déplacé vers une position active (P1) où il s'oppose au mouvement d'une barre et vers une position inactive (P2) où elle autorise le mouvement de ladite barre, le dispositif objet de l'invention ayant par ailleurs un moyen de désactivation (54, 64, 66) servant à libérer l'élément de transmission (28) et à autoriser le déplacement de l'élément de blocage (PVI) de sa position active (P1). Cette invention troue une application en particulier dans les serrures s'ouvrant à certaines conditions et, plus précisément dans les serrures à minuterie.
