  • an electrically actuated lock with a guided in a lock housing, actuated by an electric drive latch and a the electric drive superimposed, mechanically operating emergency release for the bolt, the emergency release by means of an electrically operated locking device can be blocked, characterized characterized in that part of the emergency release is a locking mechanism, and that by the locking device, the locking mechanism or parts thereof are lockable.
  • Preventive locking device In cases where an unauthorized person is the key to the Emergency release authorized, this can be done by means of electrically operated Preventive locking device are locked, which provided according to the invention is that part of the emergency release is a locking mechanism, said by the Blocking the locking mechanism or parts thereof are lockable.
  • the lock according to the invention is part of the Emergency unlocking a locking mechanism, whereby by the locking device, the locking mechanism or parts of it are lockable.
  • an emergency lock can be locked, which locks the locking mechanism when the locking mechanism is actuated entraining.
  • part of the locking device is an electrically actuated Locking element which locks the emergency release in a first position and in releases a second position.
  • the blocking element may e.g. through an electromagnet be collectible.
  • the blocking element is to a gate valve with the direction of movement transverse to the direction of movement of Notriegels.
  • the emergency bolt with a driver is engaged, and that the driver with a in the lock housing mounted operating part can be coupled, which by the electric drive is operable.
  • a preferred embodiment of the lock characterized by a spring on the driver arranged, positively coupled with the actuating part driver element. Due to the resilient arrangement of the driver element on the driver arises a catching device, which is a coupling between driver and Actuating to bring about regardless of the position of the operating part can.
  • the locking mechanism preferably with a locking fuse against premature Remove the key provided, the Verschlußommeselement via a mechanical transmission element with the Locking element in the sense of blocking the emergency release can be coupled.
  • the blocking element acts on the bolt, wherein the blocking element blocked the bolt in the locked position against opening and in the Release unlocking position.
  • the blocking element is located always and completely within the lock housing. It does not exercise itself therefore Function of a bolt, but works as a secondary blocking element, which in turn blocks the bolt in the locked position against opening.
  • the simple mechanical structure, as in the Closed position of the lock only the bolt from the lock housing protrudes.
  • the blocking element is always complete and thus tamper-proof within the lock housing.
  • the emergency release is preferably by means of the Closing mechanism with the operating part coupled.
  • the locking mechanism is functional completely independent and in particular separate from the electromotive means for actuating part and bolt.

This way, it can be centralized for each one Lock check its operating position. Furthermore, manipulations can be Immediately notice.
  • the lock can with a built-in lock housing profile cylinder for be switched on and off the electric drive.
  • They are For verification of the access authorization, other means are conceivable, e.g. in the Lock housing integrated receiver of a transmitter and receiver composite transponder system.
  • the electrically operated lock is located in a box-shaped lock housing 1 and is fastened by means of a Stulpes 2 in a door.
  • a bolt 4 is mounted horizontally on guide pin 3 fixed to the housing.
  • a bolt head 5 of the bolt protrudes from the forend 2 of the Lock case out, if the latch 4 is in its closed position.
  • a case slope 6 is formed, as, as will be described in more detail below, the latch 4 in the described Embodiment simultaneously performs the function of a trap and he therefore Also referred to as a "latch trap".

In the position shown in Figure 1 of the motor carrier 16 engages the worm shaft 14 of the electric motor form fit in the Gears 12 of the reduction gear. If, however, the engine mount 16 in Clockwise pivoted about the pivot axis 15, this leads to a separation the power flow between the electric motor 13 and reduction gear and thus to a separation of the power flow between the electric motor and the actuating part 10th
  • the guide 19 is executed as forced guidance in the form of a once obliquely bent long hole, whose first area is inclined both to the direction of movement of Operating part 10, as well as obliquely to the direction of movement of the blocking element 8 runs.
  • the movement of the operating part 10 therefore results due to the oblique Section of the guide 19 to an upward in the drawing Movement of the blocking element 8.
  • the blocking element 8 is moved from its blocking position transferred to its unlocked position.
  • the latter is characterized in that a blocking element 20 of the blocking element 8, which initially in the range of motion of the bolt 4 protrudes and therefore blocked, with the blocking element is withdrawn and thus releases the range of movement of the bolt 4.
  • a second coupling device 17a unlike the first coupling device 17 between blocking element 8 and actuating part 10, exclusively becomes active over the second range of movement of the operating part 10.

Near the end of the screw 29 is a fixed to the housing Holding element 27d for the screw and also firmly in the lock housing 1, another button 31, which detects the end of the screw 29. So if the screw 29 is screwed out of the thread 27b, this already leads after a few turns to a switching contact on the button 31, what with it a signal delivery leads. In this way manipulation attempts are counteracted, to remove the profile cylinder 27.

  • Upon further movement of the driver 34 is then a forced coupling the translational movement of the actuating part 10 with the rotational movement of the driver 34.
  • the driver element 35 on the driver 34 ensures that the catch pin 36 in can snap in any case in the recess 37 of the operating part 10, and although independent of the position in which the operating part 10 is currently located. Once on the catch pin 36 of the positive connection between the driver 34th and actuating member 10 is made, the actuating member 10 and thus also pull back the latch 4 completely until the door is opened.
