Definitions

  • the invention relates to a double lock cylinder with an electrical locking device according to the preamble of the main claim.
  • Such a locking cylinder is known from German Offenlegungsschrift 37 12 300.
  • a disadvantage of this locking cylinder is that the locking device is operated from a power supply arranged outside the locking cylinder.
  • the lock cylinder and lock must be coordinated. This is particularly disadvantageous if, for. B. a standardized door lock or the like to be retrofitted with a generic double lock cylinder.
  • the invention is therefore based on the object of providing a generic double lock cylinder which can be used independently of a special design of the lock or the like carrying it.
  • an autonomous locking cylinder which, despite the electrical locking device, has no interfering power-conducting connections to the lock.
  • the generator arranged in the locking cylinder, the generator delivers electrical energy each time the lock is actuated can operate electrical locking device. This can be done, for example, by turning the key.
  • the rotation of the cylinder core generated in this way is transmitted to the rotor of the generator arranged coaxially to the cylinder core by means of a transmission gear.
  • Transmission gear and generator are preferably arranged one behind the other, wherein they lie coaxially in the associated cavity of the housing.
  • the locking member arranged between the key-operated cylinder core and the cylinder core formed by the generator, which is rotationally driven with the key tip, is coupled to the transmission gear via an axially displaceable driving member.
  • This ensures a fixed rotary connection between the appropriate key and generator.
  • the accumulators are preferably received by a rotary knob which is arranged on the generator-side end of the locking cylinder.
  • An electromagnetically operated locking pin is provided as a locking device, which blocks the rotation of the closing member.
  • the unlocking is also be effected by axially actuating the rotary knob against spring loading.
  • the rotary knob is brought into rotation with the locking member, so that the locking cylinder also on the rotary knob side can be actuated.
  • Coupling members of the closing member and the sleeve extension of the rotary knob are brought into engagement with one another.
  • the stator rigidly connected to the rotary knob becomes the rotor, while the transmission gear, which otherwise drives the rotor, is held on one side, since the rotary movement of the closing element is blocked by the locking device.
  • the electrical connection between the rotating stator and the lock cylinder housing is made by means of sliding contacts.
  • a special configuration of the transmission gear for example as a planetary gear, also makes it possible to operate the generator from the rotary knob even when the closing member is actuated at the same time.
  • the generator is non-rotatably connected to the lock cylinder housing.
  • the generator is arranged in a sleeve in the cylinder cavity, which protrudes from the cavity at the end of the rotary knob.
  • the closing member is permanently connected to the rotor in a rotationally fixed manner.
  • the non-rotatable connection is also effected here by a transmission gear. s there is a positive motion between the locking element and the rotary knob by means of a gear transmission, which means that a rotation of the closing member is always associated with a rotation of the rotary knob.
  • the forced operation can be achieved in that the rotary knob has an external toothing on the lock cylinder side, which meshes with a toothed wheel, which is connected in a rotationally fixed manner to one end of a shaft arranged in the lock cylinder coaxially to the cylinder axis, and which is operatively connected to the lock member by a gear arranged at another end .
  • this operative connection can consist of two further gear wheels, one of which is connected non-rotatably coaxially with the closing member and the other meshes both gear wheels.
  • the locking device can be arranged in the rotary knob, the electrical lead connection being achieved by means of sliding contacts.
  • the locking device has an electromagnetically actuated locking pin which engages in an opening of the sleeve which is connected to the cylinder housing in a manner fixed against relative rotation.
  • a push pin is provided in the rotary knob, which interacts with a trigger under the action of a spring, the displacement of which causes disengagement of the locking pin with the opening of the sleeve.
  • the generation of the electrical signal when a suitable key is inserted can either be effected by mechanical actuation of an electrical contact in the lock cylinder or can also be effected by an electronic circuit which evaluates an electronically readable coding of the key.
  • a further advantageous embodiment of the invention makes it possible to dispense with accumulators, since the suitably inserted key initially causes the locking element to be partially rotated without unlocking the electrically controlled locking device, and thus the generator via the drive of a transmission gear drives. Only in this key position rotated by an angle is a further coding of the key read to unlock the electrical locking device. The generator, which is rotated by the partial rotation, supplies the necessary electrical energy for this.
  • the transmission gear is preferably provided with a freewheel gear, so that the generator continues to run when the further rotary movement of the key is blocked by the locking device.
  • the locking device is preferably designed as an electromagnetic locking pin which interacts with a partial circumferential groove of the cylinder core. This allows the key to be turned by an angle that corresponds to the length of the groove when the locking pin is locked. According to a further embodiment it is provided that the generator is not operated only by the rotation of the key, but is already put into operation by the insertion movement of the key.
  • This can be effected, for example, by a threaded spindle arranged in a rotationally fixed manner in the cylinder core, the axial movement of which, caused by the insertion of a key, sets the rotor provided with an internal thread in rotation.
  • This configuration is particularly advantageous, since accumulators can also be dispensed with in a simple manner, since the generator can be operated even before the key secret is read.
  • Such an embodiment offers the advantage that the generator is operated even when the closing member is actuated by the rotary knob. It is envisaged that the designs of the double lock cylinder according to the invention are interchangeable with a standardized double lock cylinder without the door lock or the like additional power lines or the like must be present.
  • a coupling sleeve which is axially displaceable in the cavity accommodating the generator by inserting a key and which is rotationally entrained with the stator of the generator, which is formed by its sleeve, which is connected in a rotationally fixed manner to the rotary knob.
  • the sleeve rotates with the locking element.
  • the rotor of the generator is non-rotatably connected to a connecting piece which rotatably passes through the coupling sleeve and which is non-rotatably connected to the key-side cylinder core when the key is not inserted.
  • a key can only be partially inserted into such a locking cylinder up to a first key insertion position.
  • the mechanical tumbler pins do not initially enter the notches in the key assigned to them.
  • the electronic key secret of the key can be read. If the key has the right key secret, the axial displacement of the coupling sleeve and the connecting piece rotatably connected to it is released. As a result, the key can be moved up to the second key insertion position, at which - assuming a suitable mechanical locking secret - the cylinder core can be rotated by the key.
  • the rotary movement of the connecting piece causes the rotor of the generator to rotate via the above-mentioned transmission gear.
  • the connecting piece preferably has a cylindrical shaft and, when the key is removed, its hammer head-shaped end is in positive engagement with the lock cylinder core.
  • the connection piece and coupling sleeve are preferably moved against spring loading. It is envisaged that the coupling sleeve is in rotational position with the generator sleeve in every displacement position.
  • the coupling between the locking member and coupling piece is preferably designed as a claw coupling. It is envisaged to design the slide-in lock as an electromagnetically operated locking device that blocks the axial displacement of the coupling sleeve and the connecting piece.
  • the locking device preferably has a driving pin which can be displaced in a longitudinal slot assigned to the locking cylinder housing and which engages with a circumferential groove of the coupling sleeve and, in the event of axial displacement, rotates an angle lever about an axis of rotation, the angle lever inhibiting the axial displacement of the driving pin and coupling sleeve when the magnet is de-energized to a displaceable by the electromagnet, penetrating the longitudinal slot Lock pin strikes.
  • a further advantageous embodiment of the invention has an outer locking bit that surrounds the locking bit in a bow shape and from which the locking bit is rotatably received. When the key is removed, the connecting piece is coupled to the outer lock bit so that it cannot rotate.
  • the lock bit which is rotatably driven by the coupling sleeve, can be moved by turning the rotary knob while simultaneously actuating the generator, the rotor being stationary.
  • the hammer-head-shaped end of the connecting piece is moved into a correspondingly shaped recess in the locking bit, so that the cylinder core, outer locking bit, locking bit and connecting piece are rotatably driven with the rotor of the generator.
  • the locking pin is shifted and releases the rotary movement of the outer lock bit.
  • the coupling sleeve enters with its external toothing into an internal ring gear that is connected to the lock cylinder housing in a rotationally fixed manner and is thus connected to the lock cylinder housing in a rotationally fixed manner.
  • the double locking cylinder 1 is actuated with a key 2, which is provided with coding notches 103, which cooperate with tumbler pins 4, of which only the innermost one is shown, which at the same time also supplies an electrical signal required to control the electrical locking device.
  • the tumbler pin in this case has a contact pin 6 which interacts with a contact piston 7 which is mounted in an electrically insulated recess 5 against spring loading.
  • the sleeve extension 9 is one on the cylinder cavity 8 opposite the key cavity Inserted the rotary knob 3 and thus forms the cylinder core 27 carrying the generator 24.
  • the generator 24 with transmission gear 23 is arranged coaxially to the cylinder cavity 8 in the sleeve extension 9 of the rotary knob 3.
  • the stator of the generator 24 is firmly connected to the sleeve 10, which in turn is firmly connected to the rotary knob 3.
  • the rotor of the generator 24 is connected in a rotationally fixed but axially displaceable manner to the closing element 12 via a transmission gear 23 with a driving element 11. A slight rotation of the locking element, caused by the key rotation, causes a large number of rotor rotations.
  • the locking of the double locking cylinder is effected by a locking pin 13 which projects into an opening 14 in the locking member 12 and which cooperates with an electromagnet 16 against the load on the spring 17 via a ferromagnetic armature 15.
  • the electromagnet 16 does not flow through current, so that the locking pin 13 is held by the leaf spring 17 in the opening 14 of the closing member 12.
  • the locking can be released in that the electromagnet 16 attracts the armature plate 15 by applying voltage and thus moves the locking pin 13 out of the opening 14 and releases the turnstile of the closing member 12.
  • a current-free unlocking is also provided, in that the rotary knob 3 is acted upon axially and is moved into the cylinder cavity 8 against the load on the spring 33.
  • the anchor plate 15 is pressed down by the action of the trigger 18 through the end edge 19 of the sleeve extension 9, so that the locking pin 13 emerges from the opening 14.
  • Cam-shaped coupling members 34 of the locking member 12 snap into corresponding recesses 35 of the sleeve extension 9 of the rotary knob 3. A turning of the In the coupled position, the rotary knob enables the closing element to be operated without, however, operating the generator.
  • the electrical connection between the lock cylinder housing 1 and the rotary knob 3 is established by means of the sliding contacts 20, 21.
  • accumulators 22 are arranged in the rotary knob and are charged by the generator 24 when the lock is actuated.
  • the locking cylinder works as follows:
  • a suitably coded key 2 effects an electrical connection between the two contact means 6 and 7.
  • This electrical signal causes the release of the electrical current to the electromagnet 16, which pulls the armature plate 15 against the load on the leaf spring 17 and thereby moves the locking pin 13 out of the opening 14 and so unlocks the locking member.
  • the key 2 can now turn the locking member 12.
  • the closing member 12 is connected via the driving member 11 to the transmission gear that drives the rotor of the generator 24.
  • a small turn of the key generates a large number of rotor revolutions in the stator combined with a power generation for charging the accumulators.
