Definitions

  • the invention relates to a door lock according to the preamble of claims 1 and 15.
  • door locks by Actuation of the lever handle not only the latch, but also the bolt is pulled in, which is otherwise only possible by turning the key separately or by electromagnetic or motor means can be reached.
  • the simultaneous retraction of the trap and Bolt became known through the so-called panic locks, which from a lock side without a key through bare Actuation of the door handle can be opened.
  • DE-A-41 10 556 is a generic comparable Door lock became known in its lock case an energy accumulator arranged in the form of a compression spring is.
  • the lift mechanism is activated by opening the Lock rechargeable and by pressing a button on Door frame can be released. With the help of the energy accumulator The latch can be extended to the closed position.
  • Gearbox for actuating the bolt is primarily a rack and pinion gear, that locked with a ratchet tooth can be. Apart from the complex gear arrangement this locking mechanism has the disadvantage that only within the specified tooth pitch can be blocked.
  • the lock is said to have a high level of tamper resistance and operational reliability, and it is intended to drive Enable locks in a simple way. This task is achieved according to the invention with a door lock that the Features of claims 1 and 15.

  • Position sensor and the trap can be the complete Closing position of the door can be determined, after which the Preload spring is released and the bolt on the gear is extended again. Since the bar is at least in one End portion of its retraction movement in any retreat position can be locked, the door can be wide enough Air gap between frame and door even without a complete one Pulling the bolt into the lock case can be opened. Automatic locking when the door is closed again is still guaranteed.
  • the door lock is also functionally particularly simple because that the gearbox has a nut pivot lever connected to the nut part has on a linearly displaceable Push rod attacks, the push rod over a guide link is connected to the bolt and the bias spring and attack the locking mechanism on the push rod.
  • the linear push rod movement is particularly easy to open Transfer locks. To operate the lock Avoid excessive torque on the nut part the gearbox has a specific gear ratio. With the linear push rod one can do enough great distance to be covered without excessive To use force.

  7. Serrure pour porte selon la revendication 6, caractérisée en ce qu'il est prévu, monté pivotant sur le pêne demi-tour, un levier de commande (58) à l'aide duquel le cliquet de blocage (57) peut être commandé, en ce que le palpeur de position (6) est désaccouplé du pêne demi-tour, étant précisé qu'il est apte à être rétracté avec le pêne demi-tour, et en ce que lors d'un déplacement relatif entre le pêne demi-tour et le palpeur de position, quand le pêne demi-tour sort, le levier de commande est actionné et le cliquet de blocage (57) est apte à être débloqué.
  8. Serrure pour porte selon la revendication 7, caractérisée en ce que le palpeur de position (6) comporte une came de commande (62) qui coopère avec le levier de commande (58) pour que le cliquet de blocage (57) ne soit débloqué que lors de la phase terminale du mouvement de sortie du pêne demi-tour.
