Definitions

  • the invention relates to a lock with an actuating element which is arranged rotatably in a housing and which is coupled to a driven part which is rotatably mounted in the housing in order to transmit a rotation to the driven part only if locking is authorized, the driven part being able to rotate the actuating element between a blocked position and a release position displaceable closing element, for example a bolt or a closing element.
  • the invention also relates to a lock cylinder with a cylinder core which is rotationally coupled to a locking element when a key is inserted into a key channel of the cylinder core.
  • the DE 11 2007 001 299 B4 describes a so-called cam lock for a door or cabinet.
  • an actuating element designed as a handle, which can be rotated to actuate a swivel bolt located at the end of a shaft.
  • the actuating element In a normal position, the actuating element is secured against rotation with respect to the housing by a ratchet.
  • the actuating element In the case of locking authorization, the actuating element can be rotated relative to the housing.
  • the actuating element is coupled to the shaft, so that when the locking mechanism is released, the bolt can be brought from a blocked position into a released position.
  • the DE 34 24 943 A1 discloses a lock that can be fastened to a door leaf and has an actuating element designed as a rotary knob is coupled with locking authorization with a handle mandrel to close a mortise lock located in the door.
  • Authorization to lock is determined by inserting a key card into a slot in the lock housing.
  • the DE 203 17 239 U1 discloses a lockset in which a lock is connected to a clutch with a lock mandrel. In a coupled position, the handle mandrel is carried along when the handle is rotated. This does not occur in a non-clutched position.
  • the DE 201 00 424 U1 describes a profile cylinder with a knob.
  • a profile cylinder with a knob is known, in which a predetermined breaking point is provided. If the predetermined breaking point breaks, the knob can shift axially, so that a blocking pin enters a blocking recess, so that the knob can no longer be rotated.
  • the EP 3 670 791 B1 describes a double lock cylinder with a clutch which couples one of the two cylinder cores to a locking element, elements of the clutch being able to be displaced with the tip of a key inserted into the keyway of the cylinder core.
  • Furniture locks are also known from the prior art in which an actuating element has a reading device with which an electronic key, for example a transponder, can be read. If the electronic key has locking authorization, the actuating element is coupled to a coupling element, so that the rotary movement of the actuating element can be transmitted to the bolt. When the operating member is not coupled to the coupling member, the operating member can be rotated freely.
  • an electronic key for example a transponder
  • the object of the invention is to improve the locking security of a lock characterized at the outset.
  • a rotation-inhibiting latching connection between the driven part and the housing is proposed.
  • the driven part and the closing element interacting with it for example the bolt carried by the driven part, remain in a defined rotational position in an operating position in which the driven part is not coupled to the actuating element, i.e. either in a release position or in a locked position .
  • a torque can be applied to the driven part.
  • the latching connection between the driven part and the housing is to be canceled in order to shift the closing element by further subsequent rotation of the driven part, for example to shift the latch between the locked position and the release position.
  • the driven part is in an initial position, which can be a locked position or a release position of the bolt, but which can also be an intermediate position, latched to the housing, so that the bolt cannot move into its operating position due to vibrations or gravity , For example, the locked position or release position can leave.
  • the actuating element cannot be coupled to the driven part, so that it can rotate freely.
  • a coupling projection can enter a coupling recess of the driven part in order to establish a non-rotatable connection between the actuating element and the driven part.
  • the snap-in connection forms a first snap-in element which is firmly connected to the housing.
  • a second locking element can be provided, which is formed by the driven part.
  • One of the two latching elements can be displaceable relative to the housing and against the restoring force of a spring element.
  • the other locking element can be axially fixed relative to the housing.
  • the driven part can be locked in different rotary positions.
  • an axially movable latching element surrounds a coupling element of the driven part.
  • the latching element can be an annular body and the coupling element can be coupled to the actuating element in the manner described above. In the latching positions, a latching element formed by a pin can engage in the latching depressions.
  • the latching projection can be formed by a free end of a pin which is inserted in a bore in the housing and whose free end engages freely in a cavity in the housing in which the driven part is located.
  • the spring element preferably acts in an axial direction in relation to the axis of rotation of the driven part and acts on the locking element into the locking position.
  • a rotation of the coupling element relative to the latching element can lead to an axial displacement of the latching element, which causes the latching projection to emerge from the latching recess.
  • the coupling element has a control bevel which interacts with a control element.
  • the control element can be a control element that is firmly connected to the axially movable latching element and can be formed by a diagonal pin.
  • the control bevel can be formed by a V-slot of the coupling element.
  • the coupling element preferably has two V-recesses through which a control pin reaches.
  • the opening of the coupling element, into which one end of a control pin preferably engages, can also be heart-shaped.
  • the control element connected to the axially movable latching element preferably interacts with the control bevel of the coupling element in such a way that a relative rotation of the coupling element with respect to the axially movable latching element results in an axial displacement of the latching element, in which case the latching connection is released.
  • the locking element has a ring shape.
  • the ring body formed in this way has two diagonally opposite bores, in each of which a free end of a control pin is inserted.
  • the driven part has a driven element.
  • the coupling element has an end face which is supported on a support shoulder of the driven element.
  • the driven part or driven element can have a threaded section which protrudes backwards out of the housing cavity of the housing and to which the pivot bolt is fastened.
  • the coupling element can be plugged into a cavity of the driven element that is open toward its end face. The bottom of this cavity can form the support shoulder.
  • the detent element cannot twist relative to the output element because the control pin, which is connected to the detent element in a rotationally fixed manner, is guided in the guide slots of the output element.
  • the latching element can shift in the axial direction relative to the driven part or driven element.
  • the locking depressions are arranged on a narrow edge of the ring-shaped locking element.
  • the narrow edge of the latching element can form a free space that extends over a circumferential angle of approximately 90°.
  • the two ends of the free space can form stops.
  • the detent depressions can be located in a wall of the free space that extends on a peripheral line, so that the detent pin, which engages in the free space or also the detent depressions, also forms a rotary stop at the same time, with which the angle of rotation by which the driven part or the elements of the output section can be rotated is limited.
  • the driven part or driven element has a recess, which is preferably a circumferential recess that extends over a limited circumferential area.
  • the locking pin and in particular a locking projection formed by the locking pin can reach through this recess, so that the two ends of the recess also form rotary stops.
  • a tension spring can be provided which has a first end which acts on the control pin.
  • the tension spring can extend through a central cavity of the driven part or driven element.
  • the other end of the tension spring may be attached to a pin which crosses the central cavity of the output part or element. With the spring element, a spring force can thus be applied between the latching element and the driven part.
  • the invention can be implemented in a furniture lock, which has an elongated housing in an opening of a drawer or a Furniture door can be used.
  • the furniture lock can be operated with a rotary knob.
  • a swivel bolt can be pivoted, which in a restrained position restrains the drawer or the furniture door in a closed position. In a release position, the drawer or the furniture door can be opened.
  • the invention can also be implemented on other locks, for example a lock cylinder.
  • An exemplary embodiment of the invention is, for example, a lock cylinder and in particular a knob cylinder.
  • the lock cylinder has a housing that has, for example, a standard cross-sectional profile.
  • the lock cylinder can be a half cylinder or a double lock cylinder. It is in particular a knob cylinder.
  • An actuator, which forms the actuating element and can be a shaft, is inserted in a core bore of the housing.
  • An operating knob can be connected to this shaft.
  • the shaft is connected to a clutch which is arranged in the housing and which can interact with a locking element.
  • a latching element can be brought out of a latched position along with a first rotation of the shaft or an actuating button seated on the shaft.
  • the locking element is preferably non-rotatably connected to the coupling element. In the latched position, however, the latching element is restrained against rotation relative to the housing by means of a latching projection, for example the free end of a latching pin.
  • the first rotation of the shaft which preferably takes place against the restoring force of a spring element, leads to a displacement of the locking element, in particular in the axial direction, so that the locking projection emerges from a locking opening of the locking element and thus releases the locking element for rotation.
  • the driven element can be rotated.
  • the coupling element interacts with the driven element in such a way that a relative movement and in particular a relative rotation between the coupling element and the driven element brings the locking element from its locking position into a release position. This takes place against the restoring force of a spring element.
  • the spring element can be a compression spring which is supported on the actuator, for example a shaft inserted in the housing cavity.
  • the shaft can have an end bore, in which the compression spring is inserted, which can act on a transmission element, which has an opening, which is in particular a transverse bore, in which a control pin is inserted, which is located by the spring in a crest area of two control bevels, the V - literally stand by each other.
  • the two control bevels are formed by the coupling element, which is non-rotatably connected to the actuator.
  • the coupling element can also be connected to the actuator in the same material.
  • the control pin crossing the coupling element can engage in a guide slot of the driven element. Provision is made in particular for the two ends of the control pin to engage in bores in the latching element and in an opening, for example a guide slot, in the driven element.
  • the locking pin can be inserted in a borehole arranged in the profile section of the housing of the lock cylinder.
  • a latching projection of the latching pin can protrude from this bore and interact with the latching depressions of the latching element arranged on a circular arc.
  • the driven element can transmit its rotation to the rotation of a locking element, with which a mortise lock can be actuated, for example.
  • An optional coupling can be provided with which the driven element can be brought into a non-rotatable connection with the closing element. This is provided in particular when the lock cylinder is a double lock cylinder in which a cylinder core is inserted in one housing half, which cylinder core can be turned with a key and which is held in a locked position with tumbler pins.
  • the cylinder core is coupled to the closing element with the help of the clutch.
  • the output element can then not be coupled to the closing element.
  • the output element is permanently coupled in rotation to the closing element and the latching connection between the latching element or the output element and the housing is canceled with the key.
  • the closing element can also be turned by turning a knob if the latching connection is released by applying a torque. Due to a preferably permanent rotary connection of the driven element, the rotary movement of the knob is transmitted to the closing element.
  • the driven element can also be coupled to the locking member via the clutch if the locking cylinder is to be actuated via the actuating button which interacts with the actuator.
  • a transmission element is displaced, which interacts with the clutch in such a way that an axial displacement of the transmission element leads to a clutch of the closing element with the output element.
  • a driver acted upon by a spring can be displaced axially in the direction of the closing element, so that the driver, which interacts with driving flanks of the driven element, can be coupled to the closing element in a rotationally fixed manner.
  • the invention relates to a lock cylinder with a cylinder core which, when a key is inserted into a key channel of the cylinder core, can be brought with a locking element into a coupling position which transmits rotation from the key to the locking element.
  • a driven element which is permanently coupled in rotation with the closing element can be held in a latching position which is non-rotatable with respect to the housing. Due to the rotary coupling of the output element to the closing element, the closing element is also relative to the housing as long as non-rotatable until the locking elements are brought out of their locking position.
  • this can be done by the key tip of the key inserted in the keyway displacing a transmission element in such a way that the locking connection between the two locking elements is canceled.
  • the security of a lock cylinder is improved since the locking element receives an additional rotation restriction, which acts in particular on the inside of the door, since the latching elements are arranged on the side of the lock cylinder opposite the cylinder core actuated by a key.
  • That in the Figures 1 to 16 lock shown consists essentially of a housing 9, which has a thread on its peripheral surface, onto which a fastening nut can be screwed.

  • An actuating element 1 forms a rotary knob with which the lock can be operated.
  • In a housing of the actuating element 1 there can be an electronic circuit which interacts with a reading device in order to read out an identifier of a transponder. If the transponder has locking authorization, the actuator 2 , which is non-rotatably connected to the actuating element 1 , is connected to the coupling element 3 in that the coupling projection 26 engages in a coupling recess 25 .
