Definitions

  • the invention relates to a lock cylinder, in particular for a mortise lock from a cylinder housing with a locking part recess and at least a rotatable cylinder core, a key channel provided in the cylinder core, into which a key can be inserted, the profiling of which is provided at least one Pin tumbler controls that come from a hole in the cylinder core guided core pin and a spring-loaded housing pin provided in the cylinder housing is formed as well as one that can be actuated by an electromagnet with an armature, the rotatability of a locking part influencing locking device by a electronic coding based on the energy and data exchange between the control electronics of the key and the cylinder electronics in the cylinder housing can be actuated.
  • a locking cylinder is known from EP 0 882 858 A2, in which the last of the pin tumblers in the insertion direction of the key is provided with a locking device in the form of an additional locking pin.
  • the core pin has a blind hole which is aligned with a through hole in the housing pin.
  • the additional locking pin is guided in this bore made coaxially to the housing pin and has an enlarged foot, the diameter of the foot corresponding to the diameter of the housing pin.
  • the diameter of the locking pin is smaller than the diameter of the pin bore, so that the foot can be cushioned against the housing pin by means of a spring surrounding the locking pin. This pushes the pin tumbler towards the cylinder core.
  • the base of the locking pin rests on the electromagnet equipped with an armature.
  • the armature which can be displaced in the axial direction, has a large-diameter and a small-diameter area, these two areas being separated from one another by a frustoconical bevel.
  • the electromagnet is arranged on the end face below the pin tumblers and parallel to the longitudinal axis of the locking cylinder in its cylinder housing.
  • a connecting cable connects an antenna located in the cylinder housing and the electromagnet to a transmitting part, control electronics and a power supply.
  • the transmitter part, the control electronics and the energy supply in the form of batteries are provided in a separate housing which can be arranged below or above a mortise lock behind the cuff of the door.
  • the mortise lock can be actuated by means of the locking bit of a locking part which is also provided on the locking cylinder.
  • the key is equipped with a transponder. If the control electronics receives the signal from a magnetic switch on the first pin tumbler that a key is to be inserted, the control electronics cause the transmitter to emit an electromagnetic signal via the antenna. This signal is received by the transponder of the key as energy, which the transponder needs to send an electromagnetic coded signal back to the antenna. The control electronics then evaluate the signal picked up by the antenna. If this signal is the correct code documenting the access authorization, the electromagnet is activated and the armature is withdrawn, as a result of which the base of the locking pin rests on the area of the armature with a small diameter.
  • the locking pin has thus moved downwards so far that its front edge lies below and the contact surfaces between the core and housing pins lie on the joint between the cylinder housing and the cylinder core.
  • the key can be turned with the cylinder core in the cylinder housing, whereby the operative connection to the locking part is established via a coupling and the locking bit can subsequently actuate the mortise lock to implement the locking process.
  • This solution has many disadvantages. This requires complex and fault-prone wiring of the assemblies of the electromechanical locking device and additional space in the door for the separate housing with the transmitting part, control electronics and the energy supply (batteries).
  • the additional electromechanical locking device is integrated into one of the mechanical pin tumblers, this mechanical pin tumbler can no longer maintain its mechanical locking function if the components (electromagnet, armature, base of the locking pin) of the additional locking device are damaged .
  • high safety requirements can only be met to a limited extent due to the small number of predictable and effective mechanical pin tumblers. This deficiency could be countered by an axial extension of the locking cylinder, but due to the installation conditions for the integration of the locking cylinder into the mortise lock, there are not regularly given, especially also from a security perspective (avoidance of the locking cylinder protruding from the door fitting).
  • the energy source with the control electronics in the key and the locking device that performs the locking is arranged with the cylinder electronics in the lock cylinder.
  • the locking device is designed as an electromagnetically actuated, mechanical flip-flop with a magnet armature designed as a latch, which releases a locking element that can be displaced along the longitudinal axis of the locking cylinder against the force of a spring when the electromagnet becomes effective.
  • the unlocking device is arranged essentially on the side of the locking part that faces away from the mechanical pin tumblers. To block the rotatability of the locking part, the locking element is held in a form-fitting manner in the longitudinal grooves of the cylinder housing and of the locking part.
  • the locking element can act upon the spring compressed by the key and the spring force that subsequently becomes effective from the area of the locking part move.
  • the rotational blocking of the locking part in relation to the cylinder housing is thus removed.
  • the mortise lock can be closed with the lock bit, provided the coupling between the cylinder core and the lock part is still present, and provided that the key also correctly positioned the mechanical pin tumblers of the lock cylinder designed as a half cylinder, by rotating the cylinder core together.
  • This solution has the disadvantage that it unites through its axial mode of operation takes up considerable space in the cylinder core and cylinder housing, so that one way of arranging a second cylinder core with mechanical Pin tumblers not only do not exist, but an action of the locking device on the cylinder cores located on both sides of a double locking cylinder impossible to secure by the axial movement of the locking device is.
  • the invention relates to a lock cylinder in which the electromechanical Locking device for releasing and establishing the rotationally fixed connection between Locking part and cylinder core itself do not take up any space within the for the pin tumblers reserved area in the cylinder core and / or the cylinder housing and both with just one electromagnet with armature and locking device double-sided lockable double cylinder as well as a one-sided lockable half cylinder can be operated.
  • the task is in a generic lock cylinder with the in the license plate of claim 1 specified features.
  • the advantages of the invention are that by the exclusive arrangement the components - electromagnet, armature and slide - in the locking part recess of the Lock cylinder housing or the components - transmission part and control element - outside the area reserved for the mechanical pin tumblers in the cylinder core and cylinder housing, the possibility is given to both a half cylinder to provide trained locking cylinders as well as a double cylinder, in the latter case no restrictions and therefore safety disadvantages with regard to the use of mechanical pin tumblers on both sides of the Lock part recess and without any restrictions regarding the number must be accepted per page.
  • both sides of the double cylinder with only one electromagnet and associated Apply locking device to anchor.
  • the claim 7 documents a feature that an optimal arrangement of the Enclosure with respect to the cylinder cores enabled.
  • the embodiment of the invention according to claim 8 ensures that Rotatable housing accommodates the electromagnet, armature, spring and slide components can.
  • the embodiment according to claim 9 enables a non-rotatable Connection between the locking part and the housing can be established easily can.
  • the feature according to claim 10 causes the operative connection between the respective cylinder core and the housing can be produced in a simple manner can.
  • FIG. 1 shows a locking cylinder 1 according to the invention in the form of a double cylinder.
  • This essentially consists of a cylinder housing 2 and two cylinder cores 3, 3 'rotatably mounted therein with a key channel 4, 4' into which a key 5 designed as a flat key (see also FIGS. 3 to 5) can be inserted.
  • variable locking notches 8 which in turn when the key 5 is inserted into the key channel 4 of the cylinder core 3 with the core pins 6 guided in bores in the cylinder core 3 along the longitudinal center plane interact.
  • this takes place in such a way that the ends of the core pins 6 on the cylinder housing side form a joint joint with the ends of the housing pins 7 on the cylinder core side, which joint then runs along the core rotational joint between the cylinder core 3 and the cylinder housing 2.
  • the cylinder housing 2 is equipped with a locking part recess 9, in which a locking part 10 suitable for actuating a mortise lock, not shown, can be connected to the respective cylinder core 3, 3' and is held so that it can rotate.
  • the locking part 10 is formed by a bush 11 to which a locking bit 12 is connected radially.
  • cylinder electronics 14, an electromagnet 15 with an armature 16 are located in the housing 13, a spring 17 being provided on the electromagnet 15 and a permanent magnet 18 on the side of the armature 16 facing the electromagnet 15.
  • the armature 16 is equipped on its side facing the housing 13 with a coupling element 19 which extends through a recess 20 in the lateral surface of the housing 13 and can engage in an locking manner in an opening 21 located in the bushing 11 of the closing part 10.
  • the armature 16 On the side facing away from the electromagnet 15, the armature 16 has an opening 22 through which a slide 23 mounted in the housing 13 and positively secured against rotation extends.
  • This slide 23 contains two roof-shaped depressions 24, 24 ′ which cooperate with an equivalent roof-shaped elevation 25 at the opening 22 of the armature 16.
  • a control element 26 in the form of a ball is located in a recess, not shown, which can be acted upon by the broad side of the inserted flat key 5, which also contains the control electronics.
  • a transmission part 27 which consists of a run-up pin 27 ', spring element 30 and stop pin 31.
  • the thrust pin 27 'on the control element side has a run-up slope 28 and at its other end a blind bore 29 into which the spring element 30 and the smaller-diameter shoulder of the stop pin 31 can be inserted.
  • This stop pin 31 realizes on its side facing the housing 13 a surface contact with the slide 23, for which purpose it penetrates a through opening 32 located in the end face of the housing 13.
  • the increase 25 of the armature 16 in connection with the electromagnet 15 represents the actual locking device, from which the rotationally fixed connection between the cylinder core 3 and the closing part 10 for actuating the closing part 10 is established or canceled.
  • the control electronics are integrated in the cover of the key 5, an antenna 33 leading from the control electronics to the tip of the key 5.
  • the locking cylinder works as follows:
  • the starting point is a lock cylinder 1 according to FIG. 2, in which the assembly formed from slide 23 and from control elements 26 and transmission parts 27 is in its starting position (equilibrium state).
  • the spring 17 is compressed and the armature 16 is initially in surface contact with the electromagnet 15 through its permanent magnet 18, as a result of which the coupling element 19 of the armature 16 does not engage in the opening 21 of the bushing 11 of the closing part 10 and thus the rotationally fixed connection between the cylinder core 3 and locking part 10 for actuating a lock, not shown (eg mortise lock) is prevented.
  • a key 5 which is authorized to access mechanically and electronically is introduced, for example, into the key channel 4 of the cylinder core 3 (see FIG. 3).
  • the mechanical pin tumblers (core pins 6 and housing pins 7) are arranged on the associated side of the locking cylinder 1 in such a way that the ends of the core pins 6 on the cylinder housing side form a joint joint with the ends of the housing pins 7 on the cylinder core side, which runs along the core torsion joint between the cylinder core 3 and cylinder housing 2 runs.
  • the axial displacement of the slide 23 causes the stop pin 31 on this side against the force of the spring element 30 to be moved out of the housing 13 until it clears the through opening 32 in the end face of the housing 13 and thus the operative connection between the housing 13 and cylinder core 3 '(see FIG. 5 in connection with FIG. 2).
  • the electronic coding of the key 5 is read out and, if there is a match, the electromagnet 15 is excited in such a way that the armature 16 is repelled by the electromagnet 15 with the aid of the prestressed spring 17.
  • the roof-shaped elevation 25 at the opening 22 of the armature 16 can move in the direction of the roof-shaped recess 24 of the slider 23 and engage in it. If the coupling element 19 of the armature 16, which is fixed in the recess 20 of the outer surface of the hollow cylindrical housing 13, is aligned with the opening 21 in the socket 11 of the closing part 10 (FIGS. 4 and 5), the coupling element 19 engages in this opening 21 and locks it thereby the locking part 10 relative to the housing 13, so that the mortise lock (not shown) can be actuated by turning the key 5 by means of the locking bit 12 of the locking part 10.
