Definitions

  • the present invention relates to a lock cylinder for a lock, in particular for a mortise lock for a door, with a housing and a rotatably mounted in a longitudinal bore of the housing shaft, with respect to the housing about a, defined by the shaft axis of rotation locking nose and with a by means of a drive operable clutch, by means of which a rotationally fixed coupling between the shaft and the locking lug can be produced in dependence on the verification of an authorization code, wherein the clutch comprises a by the drive in the axial direction of the shaft from a decoupled in a coupled position of the clutch movable slide which slider engages in the coupled position of the clutch in the locking lug indirectly or directly coupling.
  • Locks with generic lock cylinders are known from the prior art basically, both in the embodiment as a purely mechanically operating lock and in the embodiment as an electronically operating lock or combinations thereof, so that it is not a separate printed evidence at this point requirement.
  • Locks with generic lock cylinders are used, inter alia, in the entrance door area in door leaves, via a shaft of the lock cylinder, the opening and closing of the door, that is, the movement of a trap and / or a bolt is performed.
  • the shaft on a door outside a handle in particular a freely rotatable knob, which only allows actuation of the case or the bolt when previously an authorization code has been verified by the lock cylinder.
  • the authorization code can be entered mechanically or electronically. For example, it is the secret of a conventional mechanical or electronic key.
  • the authorization code can be entered in the case of electronic locks, for example wirelessly via radio, via an input keyboard or the like.
  • a construction is known for a lock cylinder, wherein the shaft of the lock cylinder is divided into two sections and has a first and a second section.
  • the two sections of the shaft can be brought into operative connection with each other by means of a coupling.
  • the coupling between two coaxially arranged parts of the first portion of the shaft is arranged and has two guided in recesses of the second part of the first portion of the shaft rolling body, which is used to establish the operative connection between the first part and the second part of the first portion Shaft by means of a movable slide in the circumferential direction of the first part of the first portion of the shaft extending recesses are inserted.
  • the slide is actuated by means of a drive.
  • the disclosure DE 20 2008 013 172 U1 a generic lock cylinder, which has made it its business, a lock, as it is from the DE 102 25 490 A1 is known to improve in terms of assembly.
  • the drive for actuating the clutch is arranged in the shaft.
  • the shaft has a shaft journal which engages in a bore of the locking lug.
  • the shaft journal comprises a radially movable pin by means of the drive, which is guided in a bore of the shaft journal. In the coupled state, the pin is moved radially outward and engages for the purpose of coupling in a recess in the wall of the bore of the locking lug.
  • an electromechanical lock which has a lock cylinder.
  • This lock cylinder has a housing with a longitudinal axis extending bore into which a shaft is rotatably inserted. At this wave a locking nose is arranged.
  • a coupling can be made depending on the verification of an authorization code, a rotationally fixed coupling between the shaft and locking lug, wherein the clutch has a by the drive in the axial direction of the shaft of a decoupled in a coupled position of the clutch movable slide, which in the coupled position of the Coupling engages directly or indirectly coupling in the locking lug.
  • the solution provides in a generic lock cylinder, that the slide has a stop which cooperates with a fixed relative to a movement of the slide stop surface such that the slide up to a predetermined speed and / or a predetermined acceleration relative to the housing from the decoupled is movable in the coupled position and is blocked when exceeding the predetermined speed and / or acceleration in its movement in the direction of the coupled position.
  • the special feature of the invention consists in the fact that the slider has a stop which cooperates with a stop surface of the housing. If the slider is moved at a predetermined maximum speed and / or a predetermined maximum acceleration in the direction of the coupled position, the stop slides on the stop surface. A movement of the slider in the direction of the coupled position is then possible. If, however, the predetermined speed and / or the predetermined acceleration exceeded, the movement of the slider is blocked in the direction of the coupled position. This is realized in that the stop of the slider when passing the predetermined speed and / or acceleration no longer slides on the stop surface, but rather rebounds from this and thereby returns to the decoupled position.
  • the abutment surface may also be provided by a component other than the housing. It is crucial that the abutment surface is designed to be stationary relative to a movement of the slider. This ensures that the slider always interacts with the stop surface when moving in the direction of the coupled position.
  • the authorization code is a lock secret of the lock cylinder Key.
  • a smart card, a transponder and the like come into consideration.
  • the privacy secret may be represented by a biometric feature of a user.
  • the slider is designed such that it can be inserted into a receptacle provided for this purpose the closing nose. This creates a positive connection between the shaft and the closing nose in the coupled position. Thus, a power flow from the shaft to the locking nose is transferable.
  • the stop surface of the housing and the stop of the slider can be formed by two mutually parallel surfaces. In contact, that is with a movement of the slider in the direction of the coupled position, then it comes to a surface contact, resulting in a comparatively inelastic shock result. This helps slide the slider on the housing.
  • the stop of the slider can also be designed as an edge. It then comes in contact between the slide and the housing to a surface-edge contact, which has a relatively elastic shock result. This assists in rebounding the slider to the decoupled position when the predetermined speed and / or acceleration is exceeded.
  • the second stop of the slider cooperates with the second stop surface. If the slider hits the stop surface with the first stop at too high a speed, it will be deflected by the pulse from its direction of movement. As a result, the second stop comes into contact with the second stop face, so that the slide is moved back into its original position.
  • the maintenance of the predetermined speed and / or acceleration in a proper movement of the slider is supported by a constant drive of the drive. This is particularly easy in the case of an electric motor, since the drive then simply a constant voltage or a constant current is applied. This can be realized by appropriate electronics and / or controls. This prevents the slider from exceeding the predetermined speed and / or acceleration during an intended movement and from unintentionally rebounding into the decoupled position.
  • the slide can be moved substantially axially relative to the shaft.
  • its function can be decoupled from a rotational movement of the shaft, in particular when arranged on the shaft, because the coupling state can only be achieved by an axial displacement of the slide.
  • a coupling effect may possibly be unintentionally achieved. This problem is completely avoided in the embodiment according to the invention.
  • the slider may be axially guided on the shaft, so that it does not depend on accelerations due to rotation of the shaft with respect to its function.
  • a slight inclination of the slider for the axial extent of the shaft is also included. This is due to the fact that certain relative rotations of the slider when changing between the decoupled are required in the coupled position. This especially if the slide slides with the stop on the stop surface of the housing.
  • the shaft has two mutually rotatable sections, wherein a first portion rotatably connected to the locking lug and the slider is disposed on a second portion of the shaft.
  • the two sections of the shaft are preferably freely rotatable relative to each other as long as there is no coupled state.
  • This embodiment is particularly suitable for door locks, in which an actuation of the lock is provided from both sides of the door, with a permanent actuation option is provided regardless of the presence of an authorization code from one side, which is, for example, a door inside.
  • the locking lug may also be integrally formed with the first portion. Only in the coupled state can be achieved by coupling the second portion of the shaft with the locking nose at the same time a coupling of the two shaft sections with each other.
  • first section of the shaft is decoupled from the closing nose in such a way that in the coupled state the second section of the shaft merely engages the closing nose and at the same time decouples the closing lug from the first section of the shaft.
  • first section of the shaft is decoupled from the closing nose in such a way that in the coupled state the second section of the shaft merely engages the closing nose and at the same time decouples the closing lug from the first section of the shaft.
  • the shaft passes through the lock cylinder and the locking nose and is provided at both ends with a handle. In this way it can be achieved that the presence of a valid authorization code is required in both actuating directions of the door.
  • the shaft comprises only one section, namely the section designed to cooperate with the slider.
  • the lock cylinder according to the invention then serves as a half cylinder.
  • the shaft comprises two sections, namely a non-rotatably connected to the locking lug portion and a cooperating with the slider portion. This is particularly advantageous in those applications in which a door from any particular page, namely that side on which the non-rotatably connected to the locking nose portion is arranged to operate at any time.
  • the slider is connected via an energy storage device, in particular a spring element, to the drive, wherein the slider engages in the coupled position in the closing lug.
  • an energy storage device in particular a spring element
  • the slider engages in the coupled position in the closing lug.
  • the slide can be driven by the mediation of the energy storage. This makes it possible to temporarily store the energy provided by the drive for a coupling process or for a decoupling operation, until the coupling process or the decoupling process can actually be carried out. Especially if for the Clutch operation or the decoupling a relative preferential position between the locking lug and the shaft in the direction of rotation is required, the energy for the operation of the clutch in the energy storage can be stored until the achievement of this preferred position.
  • the preferred position may be formed by one or more relative rotational positions.
  • the drive therefore does not need to remain activated until the actual operation of coupling or uncoupling is carried out. This type of drive thus allows a very low energy consumption.
  • the invention proves in electronic locks, which are powered by a battery with electrical energy.
  • the lock cylinder according to the invention allows a long service life of the electronic lock without battery change. Furthermore, it proves to be advantageous that only a few components for coupling or decoupling must be operated. A further reduction in energy consumption can be achieved. Due to the small number of components at the same time increases the reliability of the lock cylinder.
  • the energy accumulator can be formed by a spring element, for example a helical spring.
  • the slide can be acted upon by the force storage with a force so that it can automatically engage in the case of reaching a predetermined rotational position of the shaft relative to the locking lug in this to produce the coupled state.
  • a function of a latching is realized.
  • the engagement is possible only in one or more selected relative rotational positions or rotational positions of the shaft relative to the locking lug. This allows a coupling state can then be taken up very quickly automatically when the slider or the shaft and the locking lug are arranged in a lockable rotational position relative to each other.
  • a renewed actuation of the drive is not required, because the energy required for producing the coupling state or the uncoupling state can be provided by the energy store. This has previously received and stored the energy from the drive.
  • the slide is connected via a spring element to the drive.
  • the spring element may for example be a leaf spring, a coil spring, a plate spring or the like. This biases the slider in the event that the authorization code has been verified and a coupled condition is to be established.
  • the drive is actuated accordingly, wherein the slide due to the relative rotational position of the shaft relative to the locking nose can not yet take the coupling position.
  • an electric drive can be provided so that an electronic lock can be realized.
  • a pneumatic, hydraulic or mechanical drive in particular a manual operation can be provided as a drive.
  • the stop surface and / or the stop are aligned at an angle of 45 ° relative to the longitudinal axis of the housing.
  • the angle of 45 ° has proved to be particularly suitable in experiments by the applicant.
  • the angle can be chosen to be almost vertical, as long as the materials used by the housing and slide still allow such a sliding friction that the slide can be safely transferred from the uncoupled position to the coupled position in normal operation.
  • Much smaller angles than 45 ° should not be chosen because the slider in the event of a manipulation no longer rebounds in the uncoupled position as intended.
  • the stop surface in the housing diametrically opposite a second stop surface is arranged, which cooperates with a second stop of the slider.
  • the second stop surface may be formed parallel or substantially parallel to the first stop surface.
  • the slide rests in its uncoupled position with the second stop at least partially against the second stop surface. This ensures the greatest possible closeness between the slide and the housing in the decoupled position. If a manipulation attempt is then made, the movement path of the slider in the direction of the second stop surface is as small as possible. This further increases the safety of the entire lock cylinder.
  • the slider is formed with a bore and / or a weight for adjusting its center of gravity. This makes it possible to set the center of gravity of the slide individually. The dynamic properties of the slider can thus be adjusted extremely precisely. Subsequent adjustments through further drilling or adding weights are still possible. It is also conceivable to produce only one type of sliders, and then to individually configure the sliders for different types of lock cylinders. This reduces the number of components to be kept, and leads to lower storage costs.
  • the slide on a focus which is arranged in the connection of the slide with the drive end remote from the slide.
  • this end is meant that end of the slide which lies in the decoupled position between the two stop surfaces of the housing.
  • the center of gravity is arranged above the stop of the slider. This in turn has the advantage that a proper transfer of the slider is supported by the uncoupled position in the coupled position. This makes it possible to have a lock cylinder provide sufficient training at the same time with excellent properties in the intended use and also very high safety requirements.
  • a lock in particular a mortise lock for a door, with a lock cylinder of the invention is also proposed, wherein the shaft end carries a handle, preferably a knob or a pawl.
  • the shaft carries not only at one end, but at both ends a handle.
  • the lock with the lock cylinder according to the invention can be not only simple and inexpensive to produce, but it is also characterized by a high reliability during normal operation. This is achieved, inter alia, that the number of moving parts is reduced.
  • the security is increased massively with the lock according to the invention.
  • Fig. 1 shows a lock cylinder designed as a half cylinder 1.
  • the lock cylinder 1 comprises a housing 2 with a longitudinal bore 3.

  • the shaft 4 has a drive 7.
  • the drive 7 is presently designed as an electric motor.
  • the drive 7 drives a toothed rack via a worm.
  • the rack receives a spring element 14.
  • the spring element 14 is received by a first end of the rack and is received at a second end of a slider 9.
  • By means of the spring element 14 are forces from the rack, and thus the drive 7, transferable to the slider 9.
  • a rotational movement of the drive 7 in a translational movement of the slider 9 is transformable.
  • the slider 9 is designed to cooperate with the locking lug 6.
  • Slide 9 and closing lug 6 form a clutch 8.
  • the clutch 8 is switchable between a decoupled and a coupled position.
  • the closing nose 6 has a recess into which the slide 9 can slide. This is the coupled position in which a positive connection between the shaft 4 and the locking lug 6 is formed.
  • the drive 7 moves the spring element 14 in such a position in which the slider 9 urges under spring load in the coupled position.
  • the recess of the closing nose 6 and the slide 9 are brought into a mutually corresponding position in the direction of rotation of the closing nose 6, for example by turning the shaft 4, the slide 9 engages in the recess of the closing nose 6.
  • the described positive connection is then achieved.
  • the slider 9 has a stop 10, which is designed to cooperate with a stop surface 11 of the housing 2.
  • a stop 10 which is designed to cooperate with a stop surface 11 of the housing 2.
  • the slider 9 slides the slider 9 at a predetermined speed and / or acceleration with the stop 10 on the stop surface 11 in the direction of the coupled position.
  • an attempted manipulation of the lock cylinder 1 for example by a so-called bounce impact

  • the stopper 10 then slides no longer on the stop surface 11, but bounces by means of a partially elastic shock in the direction of the uncoupled position. This is supported by a second stop 16 of the slider 9.
  • the second stop 16 is designed to cooperate with a second stop surface 15 of the housing 2.
  • the slider 9 In a bouncing impact acting on the lock cylinder 1, the slider 9 thus initially bounces off the stop surface 11 with its first stop 10, and bounces back by a subsequent contact of the second stop 16 with the second stop face 15 in the direction of the decoupled position.
  • the slide 9 is transferred into the coupled position of the coupling 8 by a force action. Rather, it is the case that the rebound effect described becomes all the more effective the more strongly the lock cylinder 1 is driven.
  • the slider 9 has a bore 17. Through the bore 17, the mass distribution of the slider 9 is influenced. As a result, the center of gravity 18 of the slider 9 can be changed.
