Definitions

  • the invention relates to a cylinder lock with a cylinder core that can be rotated about a longitudinal axis in a cylinder housing, comprising a key channel for inserting a coded key.
  • Such cylinder locks are known and are designed to assume a release state in which the rotation of the cylinder core relative to the cylinder housing is released when a key assigned to the cylinder lock is inserted into the key channel, and otherwise assume a blocked state in which the rotation of the cylinder core relative to the cylinder body is blocked.
  • Electromechanical cylinder locks are known for switching the cylinder lock from the released state to the locked state and back.
  • EP 1 904704 A1 shows an electromechanical cylinder lock with a locking element that is movably arranged between the cylinder housing and the cylinder core and can be brought from a locking position into a release position by an electronically controllable actuator arranged on the shaft of an electric motor.
  • EP 1 904704 A1 shows an electromechanical cylinder lock with a locking element that is movably arranged between the cylinder housing and the cylinder core and can be brought from a locking position into a release position by an electronically controllable actuator arranged on the shaft of an electric motor.
  • Such known constructions have the disadvantage that an integration of the electromechanical locking device with conventional mechanical locking devices is possible only with difficulty.
  • the electromechanical locking device can be activated by an unauthorized key and lead to the release of the lock, even if the mechanical coding of the key has not been queried correctly.
  • An object of the invention is to solve these and other problems and to provide an electromechanical cylinder lock with increased security. This and other objects of the invention are achieved by a device according to claim 1 according to the invention.
  • a cylinder lock according to the invention comprises a mechanical locking slide which is movable in the cylinder core essentially parallel to the longitudinal axis of the cylinder core and is guided, preferably positively guided, on the inner circumference of the cylinder housing.
  • the locking slide has at least one radial extension, via which the locking slide is guided in at least one essentially ring-shaped housing groove running on the inner circumference of the cylinder housing.
  • a pin can be provided on the inner circumference of the cylinder housing, which protrudes into the core circumference and is guided in a circumferential groove on the cylinder core and on the locking slide. It is essential that rotation of the cylinder core is only possible if the locking slide can follow the course of the guide.
  • a locking element is also provided, which positively connects the locking slide to the cylinder core in the locked state in order to block its axial movement parallel to the longitudinal axis, and releases the locking slide from the cylinder core in the released state in order to release its axial movement parallel to the longitudinal axis.
  • an electromechanical actuator is provided, which is designed to actuate the locking element in such a way that it releases the locking slide from the cylinder core during the transition from the locked state to the released state.
  • the actuator can be designed as an electric motor; however, it can also be a linear drive or any other actuating element which can actuate the locking element.
  • the actuator is preferably also designed to actuate the locking element in such a way that it positively connects the blocking slide to the cylinder core during the transition from the released state to the blocked state. But this is not mandatory; the transition from the release state to the locked state can also be achieved in a purely mechanical way, for example by removing the key from the lock.
  • the actuator can be arranged at least partially, preferably mostly or entirely in the locking slide.
  • the locking element can be essentially cylindrical and attached to the actuator, for example to a shaft of the electric motor.
  • the locking slide in the locked state can at least temporarily assume a different axial position relative to the cylinder core than in the released state.
  • the housing groove or the aforementioned groove on the cylinder core and locking slide cannot be rotationally symmetrical relative to the longitudinal axis of the cylinder core.
  • the locking slide that is forcibly guided by the groove can thus assume a different axial position relative to the cylinder core in the locked state than in the released state. Since the locking slide is positively connected to the cylinder core in the locking state and cannot move in the axial direction, it is thus ensured that the locking slide blocks the rotation of the cylinder core in the locking state.
  • the housing groove is rotationally symmetrical relative to the longitudinal axis of the cylinder core.
  • the extension of the locking slide has an extension groove that is not rotationally symmetrical to the longitudinal axis, and the cylinder housing includes a housing pin that protrudes radially inward.
  • the housing pin is designed to engage in the extension groove in such a way that the locking slide is guided along the extension groove, which does not run rotationally symmetrically. Consequently, it is also achieved in these embodiments that the locking slide in the locked state can at least temporarily assume a different axial position relative to the cylinder core than in the released state.
  • the extension of the locking slide extends along the circumference of the cylinder core over an angle of approximately 5° to approximately 20°, preferably approximately 12.5°.
  • the locking slide has two or more axially offset extensions which are guided in two or more axially offset housing grooves of the cylinder housing.
  • the housing groove has a latching point which projects in the direction of the longitudinal axis and which is preferably formed in the form of a prong and a notch of the groove edge arranged opposite.
  • the extension of the locking slide snaps into the snap-in point in the locked state and can only be moved out of the snap-in point in the released state.
  • the extension has a contour with a point, for example a triangular, oval or diamond-shaped contour.
  • the extension groove has a latching point projecting in the axial direction, which is preferably formed in the form of a prong and a notch arranged opposite.
  • the housing pin is locked in the latching point in the locked state and can only be moved out of the latching point in the released state.
  • the housing pin can also be made here for the housing pin to have a contour with a point, for example a triangular, oval or diamond-shaped contour.
  • the locking element is arranged on the actuator, in particular on a shaft of the motor, and has a cam projecting in the radial direction, which is designed to positively engage in a recess of the cylinder core in the locked state and to leave the recess in the released state .
  • the locking slide In the locked state, the locking slide is thus positively connected to the cylinder core via the cam.
  • the actuator rotates the locking element in such a way that the cam leaves the recess in the cylinder core, so that the locking slide can be moved axially again relative to the cylinder core.
  • the actuator can be designed to rotate the locking element by an angle in the range from about 75° to about 105°, in particular about 90°, in order to move the locking element from the locked state to the released state and back.
  • a locking pin which projects into the key channel and which is designed to interrogate a coding on a key inserted into the key channel.
  • Such a locking pin is movable normal to the longitudinal axis of the cylinder core, ie, for example, from top to bottom, or from left to right.
  • the locking pin is designed in a known manner to interrogate a code on a key inserted into the key channel.
  • the locking pin moves along its longitudinal extent from a latching position in the locked state to a release position in the released state.
  • the locking pin to block an axial movement of the locking slide in its latching position and to release an axial movement of the locking slide in its release position.
  • the locking pin is preferably essentially cylindrical, mounted in a recess in the locking slide and protrudes through a precisely fitting recess in the cylinder core into the key channel. This ensures that an axial movement of the locking slide and thus an actuation of the lock is only possible when the locking pin is in the release position.
  • the locking pin has a scanning element for engaging in a coding of the key, for example a cam groove, wherein the locking pin is moved from the locking position to the release position when an authorized key is inserted by guiding the scanning element in the cam groove.
  • the scanning element can be an extension which is guided, for example, in a cam groove on the key.
  • the locking pin blocks rotation of the cam in the locking position and allows rotation of the cam in the release position.
  • the locking pin can have a recess which is arranged in such a way that it can receive the cam in the release position, while in the locking position it blocks displacement of the cam.
  • a clamping element for example a magnet or a spiral spring, which holds the locking pin in the locking position, so that the locking pin can only be brought into the release position by inserting an authorized key.
  • the clamping element pushes the locking pin back into the locking position.
  • the recess on the locking pin merges into a shoulder which mechanically moves the cam into the recess of the cylinder core during the transition from the release position to the locking position. This ensures that the locked state is assumed when the key is removed, even if the actuator is de-energized.
  • the transition between the recess and the shoulder may be at an angle of 90° or less to ensure that the locking pin pushes the cam into the recess of the cylinder core without locking when the key is removed.
  • Such a locking pin can in particular be designed in such a way that in the locked state it mechanically blocks access from the key channel to the locking element.
  • the locking pin can have electrical contacts for the transmission of electrical energy from an electrical energy store on the key to the electromechanical actuator. This is particularly advantageous when the lock does not have an energy supply but is fed via an energy store in the key. In this case, only when the authorized key is inserted is the locking element moved into the release position, thus enabling the locking element to be activated by the actuator, and then the actuator is electrically activated in order to move the cam of the locking element out of the depression in the cylinder core and into the recess in the locking element move.
