  • the movement of the latch bolt 35 to its retracted position occurs against a resilient bias provided by the spring member 36 accommodated on the registration pin 36’.
  • the retracting latch bolt 35 will engage and also move the auxiliary bolt 37 after the gap or“play” d is eliminated.
  • the activation of the lock system 100 via the handles 21, 22 also moves both the latch bolt 35 and the auxiliary bolt 37 to their respective retracted positions (corresponding to the positions shown in Figs. 10 and 11), and these positions are detected or sensed by the first and second sensor arrangements 51, 52, as described above.
  • the latch bolt 35 and the auxiliary bolt 37 are biased to return to the extended position shown in Figs. 1 to 5 by the springs 36, 38. This also assists the retractor member 42 and drive shaft 41, and thus also the door-handle 21, 22, to turn or pivot back to their respective original positions, although the torsion spring(s) in the handle mechanism 20 described above also operate in this regard.
  • FIG. 16 and 17 are intended to illustrate that the lock system of the preferred embodiment can be arranged or assembled in a left-handed configuration or in a right- handed configuration in a door. That is, it will be appreciated that the lock body unit 30 can be turned or reversed through 180° and integrated with the housing 10 and handle mechanism 20 in both orientations.
  • the drive shaft 41 and the pivot shafts 68, 88 project from the casing 31 of the lock body 30 and form the interface with the components of the handle mechanism 20 and the other components of the first and second sensor mechanisms 60, 80, respectively, within the housing 10.
  • the processor 99 may form part of a controller or monitor for monitoring lock system.
  • the controller or monitor may include communication hardware and/or software for communicating the current door state and/or any change in door state to a user or a monitoring station.

Abstract

La présente invention concerne un système de verrouillage (100) et un procédé associé pour détecter un état de porte, ledit système comprenant : un corps de verrouillage (30) qui a : un pêne (35) qui est mobile entre une position étendue et une position rétractée, le pêne (35) dans la position étendue étant configuré pour être reçu dans un évidement d'une plaque de gâche prévue sur un cadre de porte adjacent à une porte dans ou sur laquelle le corps de verrouillage est monté lorsque la porte est dans un état fermé et verrouillé, et un pêne auxiliaire (37) qui est agencé de manière adjacente au pêne (35) et qui est mobile entre une position étendue et une position rétractée, le pêne auxiliaire (35) étant configuré pour être comprimé contre la plaque de gâche dans la position rétractée lorsque la porte est dans un état fermé et verrouillé ; un dispositif capteur (50) pour détecter si chacun du pêne (35) et du pêne auxiliaire (37) est dans sa position étendue respective ou sa position rétractée respective ; et un processeur (99) pour évaluer des données en provenance du dispositif capteur (50) pour déterminer l'état de porte.
