Definitions

  • the invention relates to a lock arrangement, which is secured by both a mechanical and an electronic locking secret.
  • EP-B-224 607, EP-A-424 356 and EP-A-452 298) that the core of a locking cylinder, which can be rotated in a housing bore of a profile cylinder housing, in addition to the mechanical tumblers that can be unlocked by means of a key to lock an electromechanical locking device in the locked rotational position of the core defined by the mechanical tumblers.
  • the flat key which can be inserted into a key channel of the core, not only controls the tumblers that define a mechanical locking secret, but also carries information that can be read by the lock-side electronic control means that defines an electronic locking secret.
  • the control means check the electronic locking secret on the basis of predetermined information and accordingly control the electromechanical locking device.
  • the electronic locking secret can be used not only to increase locking security, but also for a large number of other applications, for example to control access authorizations or to control alarm systems.
  • an electronic coding circuit and an infrared transmission diode are accommodated in the key handle of the key, via which the secret data is transmitted to a lock-side infrared reception diode.
  • the receiving diode is housed in a door escutcheon that is conventionally attached to the profile locking cylinder.
  • a resilient galvanic contact is also provided in the key handle, which rests on a counter-contact on the lock cylinder side when the key is inserted into the key channel of the lock cylinder.
  • the elements to be coupled with the key i.e. the receiver diode and the lock-side contact, freely accessible and thus accessible without any manipulation.
  • the galvanic contact can also become dirty, which can lead to malfunctions.
  • the lock-side galvanic contacts are offset in the direction of rotation of the core against its locking rotational position and are therefore arranged in a concealed manner outside the area accessible through the key channel in the locking rotational position.
  • the lock-side contacts are not only protected against manipulation, but also against contamination. All data between the lock-side control means and the key-side control circuit, as well as the operating energy of the control circuit, are expediently transmitted via galvanic contact pairs of the type explained above.
  • the lock housing and the key body can also be used for contact transmission.
  • the electromechanical locking device does not have to be combined to form a structural unit with the locking cylinder; it can also be provided separately, for example in the form of a door lock, the bolt and / or the latch of which is driven by an electric motor and in this way also assumes the additional security function.
  • the electromechanical locking device may also be omitted, for example if the data of the key are only to be used to document the use of the lock arrangement, for example by storing or storing the data identifying the key and the time at which the lock cylinder was locked will.
  • the contact of the key is provided on its shaft protruding from a grip part and insertable into the key channel.
  • the lock-side is corresponding Contact concealed within the contour of the housing or a cover part fixed to it.
  • at least one of the contacts of each contact pair is designed to be resilient, expediently using resilient contacts radially to the axis of rotation of the core in order to avoid forces acting axially on the key and pushing the key out of the key channel.
  • An insulating part extends along the circumferential path of the contact rotating with the key and forms a window in its area assigned to the contact area. The insulating part ensures that the contact can only be made in the area delimited by the window and short circuits outside this area to the other components of the core or of the housing, which are also usually made of metal, are avoided.
  • the insulating part can be arranged fixed to the housing and, for example, have the shape of a ring interrupted by the window.
  • the insulating part is connected to the core in a rotationally fixed manner, in particular when the radially resilient contact is provided on the contact carrier.
  • the insulating part can have the form of an insulating sleeve or the like surrounding the core, the window of which coincides with the key channel then open to the circumference of the core.
  • the accommodation of the radially resilient contact on the contact carrier also has the advantage that the radial installation space of conventional profile cylinders can be used to save space.
  • the insulating part is guided captively radially and axially by fixing means, in particular a radially resilient locking ring seated in the through bore of the contact part, and can be coupled non-rotatably to the core via axially pluggable coupling members.
  • the insulating part which preferably forms part of the key channel, is thus rotatably guided relative to the resilient contacts of the contact carrier and, together with the contact carrier, forms a unit which may also be retrofitted.
  • the contact carrier is, as seen axially, a cover part which can be mounted in front of the housing, in particular as a lock rosette or door lock shield.
  • the cover part expediently has a cover body made of metal, in particular steel, with a cover body coaxial with the axis of rotation of the core Through opening, the narrowest diameter of which is smaller than the diameter of the housing bore receiving the core.
  • the cover body covers the front end of the housing and forms a drilling protection, for the reinforcement of which the cover body can optionally be hardened or reinforced with additional hardened steel plates. Since the through opening of the cover part is narrower than the core is thick, the cover part also makes it difficult to pull out the core according to the "corkscrew method".
  • At least some of the electronic components of the lock-side control means are preferably connected to the cover part to form a structural unit.
  • the installation space previously provided in the housing of the locking cylinder for the accommodation of electronic components is thus increasingly available for other security measures, for example core pull-out protection measures or anti-drilling protection measures.
  • electronic components in the locking cylinder can be completely avoided, which has the advantage that conventional locking cylinders can also be retrofitted with "electronic door rosettes or door plates".
  • the key is in both aspects of the invention preferably designed as a flat key, and the contact of the key is arranged on the narrow side of its shaft, which projects from a grip part and can be inserted into the key channel.
  • the contact carrier is designed as a separate component from the housing and carries at least one contact which is resiliently displaceable radially to the axis of rotation of the core. In this way, comparatively long-stroke springs can be used, which leads to uniform contact with a long service life.
  • the contact carrier preferably has at least one guide opening which is inclined against the arrangement plane of the tumblers and runs radially to the axis of rotation of the core and in which a contact element is guided in a resiliently displaceable manner.
  • Such an embodiment is particularly durable and reliable.
  • the guide openings are preferably arranged symmetrically in pairs relative to the locking rotary position, which has the advantage that the locking cylinder and its contact carrier can be used equally for both right-closing and left-closing doors. To reduce the costs, however, only one guide opening of each pair contains a contact element which, if the direction of closing changes, is possibly converted into the other guide opening.
  • these contact elements are expediently arranged one behind the other in the direction of the axis of rotation of the core for reasons of space savings.
  • each contact element can, insofar as they are against the contact carrier are otherwise isolated, form the contacts immediately.
  • each contact element has an insulating carrier, in particular designed as a pin, which is displaceable in the guide opening and at whose end facing the core the actual contact is seated.
  • FIGS. 1 to 3 show a lock arrangement with a mechanical lock cylinder 1 with a conventional profile housing 3, which in a housing bore 5 receives a core 9 rotatable about its axis 7.
  • a core 9 rotatable about its axis 7.
  • FIG. 1 shows only one of several pairs of tumbler pins 15, 17 present.
  • the core 9 of the lock cylinder 1 drives the bolt of a door lock or the like, not shown, in a conventional manner.
  • the locking cylinder 1 is assigned an electromechanical locking device 29 which, independently of the tumbler pin pairs 15, 17, prevents or releases the unlocking and / or locking of the door lock.
  • the locking device 29 indicated in FIG. 1 forms a structural unit with the locking cylinder 1 and, in the exemplary embodiment shown, comprises an electromagnet 31 in the housing 3, which latches a bolt 35 biased by a spring 33 into a position locking the core 9 when an excitation current signal is supplied from the blocking position withdraws and releases the core 9 to rotate.
  • the core 9 can thus be used despite a suitable key being inserted 23 only turn with unlocked locking device 29 for the actuation of the lock bolt.
  • the locking device can optionally also be integrated in the lock to be locked via the lock cylinder 1, for example also in the form that the bolt of the lock is in turn driven by an electromagnet or electric motor, so that the operation of the lock can be electrically
  • the key 23 contains a control circuit 37, for example in the form of a microprocessor or the like, which is galvanically connected via a plurality of galvanic contact pairs 39, 41 to lock-side control means which control the locking device 29, here a control circuit 43.
  • the control circuit 37 is supplied with operating energy via the contact pairs 39, 41 on the one hand and supplies data, which represent an electronic key secret, preferably via the contact pairs 39, 41 in digital form.
  • the control circuit 43 checks the locking authorization of the electronic locking secret of the key 23 and, if the locking secret is correct, supplies the excitation current signals driving the core 9 (or the lock bolt drive). Further, higher-level circuits, for example monitoring circuits of access control systems or alarm systems, can be connected to the control circuit 43.
  • the lock-side contacts 41 are in a separate from the housing 3 than Contact carrier trained cover part 45, here in the form of a housing 3 on the Inserted side of the core 9 covering cover rosette guided radially to the axis of rotation 7.
  • the cover part 45 which can optionally also be designed as a door cover plate and can extend as far as a door handle or a handle olive of the door lock, is fastened to the door independently of the cylinder lock 1 with screws 47 extending through the door.
  • the cover part 45 contains a continuous stepped bore 49 coaxial with the housing bore 5, the narrowest opening 51 of which is provided on the side facing away from the core 9 and has an inner diameter corresponding to the width of the shaft 27 in the region of the flat side widening 44.
  • the diameter of the opening 51 is smaller than the outer diameter of an annular collar 53 projecting radially through the bore 5 at the end of the core 9 axially adjacent to the cover part 45.
  • the core 9 can therefore also be used using the "corkscrew method", ie by means of a key channel 21 screwed self-tapping screw cannot be pulled out through the opening 51 of the cover part 45.
  • the cover part 45 is preferably made of hardened steel and, with its flat side wall 55, which completely covers the facing end face of the housing 3, forms a drilling protection for the tumbler pins 15 which are displaceably guided in the housing 3.
  • the contacts 39 of the key 23 sit in an insulating body 57 which insulates them from the shaft 27.
  • the contacts 41 are covered in the locked position of the locking cylinder 1 (FIGS. 1 and 2) by an insulating part 59 rotatably inserted in the stepped bore 49.
  • the insulating part 59 has on the side facing the housing 3 a radially outwardly projecting ring flange 61, which is seated in an extension 63 of the stepped bore 49 and from a radially resilient, into a groove of the extension 63 used circlip 65 is axially fixed together with the constriction 51.
  • the insulating part 59 which is arranged coaxially with the core 9, carries a plurality of pins 69 which engage axially in end openings 67 (FIG. 3) of the core 9 and couple it in a rotationally fixed manner to the core 9, and has a flat, axially extending the key channel 21 of the core 9 Cross-sectional contour of the shaft 27 in the area of the flat side widening 44 adapted passage opening 71.
  • the narrow side of the shaft 27 in the area of the flat side widening 44 and thus the contacts 39 radially opposite the insulating part 59 is provided with a window 73 (FIG. 2) which is approximately trapezoidal in axial cross section through which the contacts 39 of the key 23 inserted into the key channel 21 are accessible from the radially outside.
  • the contacts 41 are offset in the circumferential direction against the contacts 39 of the key 23 which are in the rotationally locked position, for example by an angle between 30 and 40 °.
  • the width of the window 73 is selected in the circumferential direction so that the contacts 41 are in the anti-rotation position outside the window 73 and are thus completely covered by the insulating part 59 and are therefore protected against contamination and against manipulation.
  • Each of the contacts 41 sits at the radially inner end of a separate insulating pin 75, which is displaceably guided in a radially extending guide opening 77 and is biased towards the axis of rotation 7 by a respectively assigned spring 79.
  • the guide openings 77 and the insulating pins 75 have an approximately rectangular cross section to prevent rotation.
  • the contacts 41 are with leads 81 connected, which are led out along the insulating pins 75 and through cutouts 83 of the cover part 45 to the control circuit 43.
  • the guide pins 75 are separated from one another by an insert 85 which, together with the guide pins 75, is inserted into a radial channel 89 of the cover part 45, which is closed radially on the outside by a plug 87.
  • the channel 89 can be designed as a bore, the guide openings 77 then being limited by the insert 85, which is preferably made of plastic.
  • FIGS. 5 and 6 show the locking cylinder 1 in the rotationally locked position of its core 9, in which the tumbler pin pairs 15, 17 lock the core 9 on the housing 3 and the key 23 can be inserted or removed. If the locking secret of the key and the locking cylinder match, the key 23 and the core 9 can be turned into the position shown in FIGS. 5 and 6.
  • the locking device 29 is designed in such a way that it permits a rotational play corresponding to the angular offset of the contacts 41, but prevents further rotation into a rotational region which allows the lock bolt to be opened.
  • the window 73 of the insulating part 59 is located radially opposite the contacts 41.
  • the contacts 41 can thus be applied through the window 73 to the contacts 39.
  • the control circuit 37 is thus supplied with operating current via the now closed contacts 39, 41 and likewise supplies data for the authorization check and unlocking of the locking device 29 to the control circuit 43 via the closed contacts.
  • the window 73 of the insulating part 59 is limited in the circumferential direction by inclined surfaces 91 which facilitate the compression and rebound of the contacts 41 when the insulating part 59 rotates.
  • the bores 89 for receiving the insert 85 and the insulating pins 75 are arranged symmetrically in pairs in relation to the anti-rotation position (FIG. 2) in order to be able to use the locking cylinder 1 equally for right-closing and left-closing doors.
  • both bores 89 are equipped with inserts 85 and insulating pins 75 in the exemplary embodiment shown, only a single set of these elements can be installed in accordance with the closing direction of the door in order to save costs. If necessary, these elements must be reassembled.
  • the openings 83 which are likewise provided symmetrically in pairs in accordance with the bores 89, are connected to one another by a slot 93 in order to facilitate the assembly of the cover part 45.
  • the control circuit 43 can be arranged separately from the housing 3 of the locking cylinder 1.
  • FIG. 2 shows a preferred variant in which the control circuit, as shown at 43 ', is integrated in the cover part 45, that is to say forms a structural unit together with the cover part 45.
  • the locking device 29 can optionally also be integrated in the structural unit of the cover part 45, so that only mechanical coupling elements, for example for the bolt 35, have to be provided on the locking cylinder 1 side. In this way, almost all functional elements for the electronic part of the lock can be integrated into the cover part 45.
