Definitions

  • the invention relates to a locking and block lock with a lock cylinder, a key-operated bolt and with a blocking device that can be switched back and forth electromagnetically between a blocking and release position and has a block magnet, whereby the locking process also enables a hazard avoidance system to be armed, the key in the locking cylinder can only be inserted in the inserted position, a microswitch is actuated by turning the key from the inserted position and the actuation of the microswitch is registered in the control center of the alarm system and used for control purposes.
  • DE-U 7 532 906 describes a lockable lock which has two microswitches, the first microswitch being actuated during the closing process and the second microswitch in the locked position.
  • the control circuit for the block magnet is closed via the first microswitch, while the alarm system is switched on by the second microswitch.
  • the microswitches are actuated when the closing process is carried out using a key inserted from one side as well as from the other side of the door.
  • the object of the invention is to monitor the start of each locking or unlocking process in the case of a block and locking lock, in order to register the actuation of the lock in a hazard detection system and, in particular, to ensure the arming of a hazard detection system according to clear criteria.
  • This object is achieved in that in front of the locking and block lock, and only on one side a key slot having, in the axis of rotation of the lock cylinder rotatably mounted contact disk is attached, which is provided with a contact surface for actuating the microswitch.
  • the movement of the contact disk according to the invention takes place via the key slot of the same by the inserted key during the closing process. If the contact disk is now only attached to one side of the locking and block lock, it can be signaled by an appropriate evaluation of the signal of the microswitch in the hazard alarm system from which side the locking operation on the locking and block lock was carried out.
  • DE-PS 16 78 661 describes a rotary cylinder lock provided with an alarm transmitter, which is formed from two locking cylinders located one behind the other. Between the two locking cylinders there are two contact disks located one behind the other in the axis of rotation of the locking cylinder, one contact disk being firmly connected to the rotatable part of the associated locking cylinder.
  • the contact disk of the locking cylinder which comes into contact with the key first during the closing process, has a nose and two recesses and the other contact disk has a recess instead of the nose, the driver wheel of a microswitch being held in the actuating position thereof by the nose. If both locking cylinders are not rotated at the same time by a common key, the driver wheel falls into a recess in the contact disk and gives an alarm because the locking cylinder has been tampered with.
  • a further development of the invention in a locking and block lock with two closed positions, the second closed position being preventable by a block magnet, consists in that by actuating the microswitch in the first closed position, the second closed position is prevented by the block magnet at the instigation of the alarm system.
  • a contact disk 1 is rotatably mounted, namely rotatably about the axis of rotation of the lock cylinder 4.
  • the contact disk 1 has a key slot 5, which in the vertical position, i.e. is held in the inserted position of the key in the lock cylinder 5. This is done by a recess 7 on the side of the contact disk 1, into which a detent spring 2 engages.
  • the contact disk 1 has contact surfaces 6 which actuate the contact of the microswitch 3 when the contact disk 1 is rotated.
  • the contact surfaces 6 are attached to the contact disk 1 such that actuation of the microswitch 3 is actuated both in one direction of rotation of the contact disk 1 and in the other direction of rotation of the contact disk 1 at the start of the rotation.
  • the key slot 5 is designed in such a way that the key can be inserted into the key slot 5 only in one position and not in the position rotated by 180 ° , then only two contact surfaces 6 and one depression 7 are necessary. Otherwise, the contact surfaces 6 and the depressions 7 are to be provided both for the one position and for the position of the contact disk rotated through 180 ° .
  • the contact disk 1 with the devices located in the housing 9 can also be accommodated in a block lock itself or, as already mentioned in the panel 8.
  • the lock carrying the locking cylinder 4 designed as a locking and block lock with two closed positions the second closed position being through a block magnet can be prevented, the second closing position can be prevented by the block magnet by actuating the microswitch in the first closed position by preventing the rotary movement of the locking cylinder 4 into the second closed position at the instigation of a hazard detection system who previously registered the operation of the microswitch during the first closing operation.
  • the arming of a hazard detection system can be prevented by a closing process inside a room to be protected if the contact disk 1 and the associated devices are attached to the door side, which faces a room to be protected in the closed state.
  • the device according to the invention can also be attached to normal keys lockable with locking cylinders, in order in this way to be able to monitor the locking and unlocking processes electrically from a registration device.

Claims (5)

1. Serrure d'arrêt et de blocage avec un cylindre de fermeture (4), un pêne actionné par une clé, et avec un dispositif de blocage présentant un aimant de blocage, pouvant être commuté par voie électromagnétique entre une position de blocage et une position de dégagement, où aussi, par le processus de fermeture, un branchement rapide d'une installation avertisseuse de danger est possible, la clé ne pouvant être introduite dans le cylindre de fermeture que dans sa position d'enfoncement, où, par la rotation de la clé à partir de sa position d'enfoncement, un microcommutateur (3) est actionné et où l'actionnement du microcommutateur est enregistré dans la centrale de l'installation avertisseuse de danger et utilisé à des fins de commande, caractérisée en ce que, devant la serrure d'arrêt et de blocage, et en fait seulement d'un côté, est adapté un disque de contact (1) présentant un trou de serrure (5), monté de manière à pouvoir tourner dans l'axe de rotation du cylindre de fermeture (4), le disque de contact étant pourvu d'une surface de contact (6) pour l'actionnement du microcommutateur (3).
2. Serrure d'arrêt et de blocage suivant la revendication 1, caractérisée en ce que le disque de contact est maintenu, par un ressort d'encliquetage (2), dans la position d'enfoncement de la clé.
3. Serrure d'arrêt et de blocage suivant l'une des revendications 1 ou 2, caractérisée en ce que le disque de contact (1) est situé à l'extérieur de la serrure d'arrêt et de blocage.
4. Serrure d'arrêt et de blocage suivant la revendication 3, caractérisée en ce que le disque de contact (1) est logé dans un capot (8) de la serrure d'arrêt et de blocage.
5. Serrure d'arrêt et de blocage avec deux positions de fermeture, où la deuxième position de fermeture est empêchée par un aimant de blocage, suivant l'une des revendications 1 à 4, caractérisée en ce que, par l'actionnement du microcommutateur (3) dans la première position de fermeture, la deuxième position de fermeture est empêchée par l'aimant de blocage sous l'impulsion de l'installation avertisseuse de danger.
