    The invention relates to a locking device according to the preamble of claim 1.
    For locking a lock usually an actuator or a handle is provided, such as a door handle, a door knob, a key or the like, the movement either directly or with the interposition of a coupling device with the closing member, such as a locking lug or a locking latch to open or closing the lock is coupled, wherein the coupling device usually couples the actuator with the closing member only when an access authorization has been established. The access authorization is controlled by electronically operated locking devices by electronic access control means, in which an identification by means of an electronic code is detected. The coupling device is usually driven by motors or electromagnetically driven to be moved between an engaged and disengaged position.
    The electronic access control means usually comprise a reading unit for reading access rights data from a ID medium, an evaluation circuit for determining the access authorization in dependence on the access right data and a cooperating with the evaluation logic unit for controlling the coupling means, wherein at least one element selected from the reading unit, evaluation circuit and logic unit in the handle is arranged and electrically connected to a arranged in the lock cylinder element. It is, for example, the coupling device together with the ···· Φ · · a ·· aa · φ ♦ φ · «· φ φ · · φ • φ · φ * t φ * · ·· 2: φ φ · associated logic unit arranged in the lock cylinder and must be electrically connected to the control and possibly power supply to the handle, in which at least a part of the other components of the electronic access control and possibly also the energy storage are arranged. The handle must be connected for assembly and disassembly purposes, but possibly also for replacing the energy store releasably connected to the cylinder core, so that in addition to the electrical and mechanical connection means are provided. The releasable mechanical and electrical connection further allows the formation of a modular system in which a lock cylinder can be selectively connected to one of a plurality of differently designed handles, for example, to accommodate different data transmission technologies for reading the access right data from a ID medium.
    The present invention now aims to make the mechanical connection between the handle and the lock cylinder in a way that, although the connection can be easily solved, but still is extremely stable and withstand high mechanical loads, for example in tampering or the like. Furthermore, the mechanical connection is to be combined in a simple manner with an electrical connection, so that when the mechanical connection is established, the electrical connection is automatically established and, conversely, when the mechanical connection is released, the electrical connection is also disconnected. < «** # * · ···« φφ ······· * * · «« · * # ·· «* ·« • · ♦ · · ··· ·· «* ·
    To achieve this object, the closing device is essentially designed such that the connecting means comprise a threaded connection between the cylinder core and the handle, wherein the threaded connection has a form-locking anti-rotation in the form of arranged on the cylinder core or the handle axial recesses into which on the other part trained projections in the screwed state of the threaded connection can engage axially. The anti-rotation device makes it possible to use a proven threaded connection for the mechanical connection of the handle to the lock cylinder, without having to accept disadvantages with regard to the rotational strength of the connection. It can be dispensed with disadvantageous plug or snap connections. The projections and recesses are arranged in particular so that the projections automatically engage or snap into the recesses when a screwed state is reached. This is ensured in particular if, as corresponds to a preferred development, the projections and / or the recesses are spring-loaded axially in the direction of engagement. By virtue of the invention, securing means to be mounted separately, e.g. Locking pins, set screws or the like not required.
    It is preferably provided that at least three recesses and projections are arranged distributed in the circumferential direction. Preferably, the at least three recesses are distributed uniformly over the circumference of the thread, so that the projections can be brought into engagement with the recesses in a number of rotational positions corresponding to the circumferential pitch. At least four are preferred,
    In particular, at least six projections and recesses are provided.
    In principle, the projections can be arranged either on the handle or on the cylinder core and the recesses on the respective other part. Due to the limited space in the cylinder core, it is advantageous if the projections on the handle and the recesses are formed on the cylinder core. This in particular if, as corresponds to a further preferred development, the threaded connection comprises an internal thread formed on an end face of the handle, in particular on a plate forming the lid of a pot-shaped knob, and an external thread formed on the cylinder core.
    The projections are in this case advantageously formed on a behind the end face of the handle, in particular behind the cover of the knob forming plate, arranged component, wherein the projections engage in recesses of the internal thread positively and protrude radially into the inside diameter of the internal thread. As a result, the part carrying the projections is also held positively in a structurally simple manner and secured against rotation.
    In order to enable the projections to engage in a form-fitting manner into the recesses only after screwing the handle with the cylinder core as completely as possible, a possibility must be provided for pushing the projections away and for engaging only after the screwing procedure. The training in this context is preferably such that the Μ Μ 44 * Μ Μ 44 * Κ

    Projection-bearing component radially outwardly of the thread arranged locking pins, which engage in recesses on the front side of the handle, in particular in a lid of a pot-shaped knob forming plate. The locking pins are in this case arranged back from the outside by means of a tool, so that the projections can be brought during the screwing using a special tool in a position in which they can not get into engagement with the recesses. Only after the handle has been completely screwed to the stop on the cylinder core, the locking pins are released and the projections acted upon by the spring force in the direction of the recesses. A turning back of the handle by a certain angle causes the projections automatically engage in reaching a covering with the recesses position in this, in order to realize in this way the positive rotation. The greater the number of circumferentially distributed projections and recesses, the lower is the required until the projections engage in the recesses return angle.
    The connection means preferably have electrical contacting means guided through the threaded connection, so that the electrical connection can be established simultaneously with the mechanical connection. In this case, the electrical contacting means have at least two electrical contacts arranged at different radial distances from the axis of rotation of the cylinder core and annular countercontacts lying at the corresponding diameter. The annular formation of the mating contacts ensures that the electrical
    Contacting is made independent of the respective rotational position of the handle relative to the cylinder core. If the electrical contacts are designed as resilient contact pins, the contact pins interact with the annular mating contacts when screwing the handle with the cylinder core in the manner of sliding contacts.
    Preferably, the annular mating contacts are designed as conductor tracks on a carrier, in particular a carrier foil.
    Preferably, the electrical contacts on the cylinder core and the mating contacts are arranged on the handle.
    According to an advantageous development, at least three electrical contacts and associated mating contacts are provided, wherein two contacts of the energy transfer from an arranged in the handle electrical energy storage to the coupling means and at least one contact of the signal or data transmission is used.
    When the reading unit and the evaluation circuit are arranged in the handle and the logic unit in the lock cylinder, the electrical connection between the handle and the cylinder core, inter alia, the transmission of control commands of the logic circuit to actuate the coupling means.
    The invention can be used within the scope of various embodiments of the clamping unit. It is therefore preferably provided that the closing unit as a double knob lock cylinder, lock cylinder with only
    • a knob, with or without key insertion function on the lock cylinder side opposite the knob, double lock cylinder, double lock cylinder with double-sided electronic or mechatronic authorization query, Half cylinder, half cylinder with knob, half cylinder with mechatronic authorization query or half cylinder with electronic authorization query is formed.
    The invention will be explained in more detail with reference to an embodiment shown in the drawing. 1 shows a lock cylinder, FIG. 2 shows a knob, FIG. 3 shows the lock cylinder from FIG. 1 with a front part of the knob, FIG. 4 shows the lock cylinder with the knob screwed on and a mounting tool, and FIG. 5 shows the mounting tool in an attached position Status.
    In Fig. 1, the lock cylinder is designated 1 and has a lock cylinder housing 2 and a cylinder housing 3 rotatably received in the lock cylinder housing 2. The cylinder core 3 consists of two axially successively arranged parts and takes on a schematically indicated clutch 4, with which the front part 5 of the cylinder core 3 rotatably connected to the rear part and the rotationally fixed connection can be released again. The front, protruding from the cylinder housing 2 Part 5 is always freely rotatably mounted in the lock cylinder housing 2. With the freely rotatable part 5, a rotary knob 6 can be rotatably connected, so that the rotational movement of the rotary knob 6 is always transmitted to the freely rotatable part 5 of the cylinder core 3. With the rear part of the cylinder core 3 is not shown closing lug or the like. Non-rotatably connected.
    As soon as the freely rotatable part 5 of the cylinder core 3 is brought into non-rotatable operative connection with the rear part of the cylinder core 3 by means of the coupling 4, a rotation of the rotary knob 6 causes an actuation of the locking nose, so that a lock (not shown) can be opened. The clutch 4 is in this case controlled by a logic unit 7, which is electrically connected by means of three electrical lines 9 with an arranged in the rotary knob 6 evaluation circuit 8.
    The rotationally fixed connection of the cylinder core 3 with the rotary knob 6 via a threaded connection, which has an external thread 10 at the projecting portion of the freely rotatable member 5 and an internal thread 11 {Fig. 2) on an end plate 14 of the rotary knob 6 comprises. To prevent rotation of the threaded connection six circumferentially regularly distributed recesses 12 are provided at the free end of the part, in which corresponding projections 13 of the rotary knob 6 engage axially in the screwed state. The projections 13 are formed on a behind the lid of the knob 6 forming plate 14 arranged plate-shaped member 15. The arrangement of the component 15 is best seen in Fig. 3, in which the component 15 as shown in Fig. 1 for the sake of clarity, not shown in the installed position, but offset to the left. In Fig. 3 it can be seen that the component 15 on the lock cylinder 1 side facing three circumferentially regularly distributed locking pins 16 carries. The locking pins 16 engage in recesses 17 of the plate 14, so that the plate-shaped member 15 is held in relation to the rotary knob 6 and the plate 14 in a rotationally fixed state.
    As can be seen in Fig. 2, the tips of the locking pins 16 protrude from the recesses 17, i. they stand out of the plate 14. The locking pins 16 simultaneously serve as assembly and disassembly aid. The plate-shaped component 15 is in fact displaceably mounted in the axial direction and acted upon by means of a spring element, not shown, in the direction of the plate 14. 4, the locking pins 16 and with them the plate-shaped component 15 can be pushed back so that the projections 13 are disengaged with respect to the recesses 12. In this position the rotation of the threaded connection is released and the knob 6 can be screwed down from the lock cylinder 1. After removing the mounting tool 18, the component 15 returns together with the locking pins 17 due to the spring force in its original position.
    The assembly tool 18 is also used for screwing the knob 6. First, the locking pins 16 are pushed back with the mounting tool 18. Thereafter, the knob 6 is screwed onto the lock cylinder 1 until it stops. Thereafter, the assembly tool 18 is removed, so that now the spring force acts on the plate-shaped component 15 in the direction of the lock cylinder 1. Thereafter, the knob 6 is turned back a little until the projections 13 dive due to the spring force in the recesses 12 and thereby prevent further backscrew.
    In Fig. 2 is schematically indicated that inside the rotary knob 6, a reading device 19 and a battery 20 are installed. The battery 20 supplies the *. * ** ** ♦ ······· *. * · .. ··· ♦ · 13: ♦ "·
    Reading device 19 and the Äuswerteschaltung 8 with power. The reading device 19 can receive identification data of an electronic key and forward it to the evaluation circuit 8, where it is checked for access authorization. If the check was successful, the logic unit 7 is activated and the clutch 4 is actuated.
    The electrical connection between the evaluation circuit 8 and the logic unit 7 by means of electrical contacts, which are designed as resilient contact pins 21 and which cooperate with two annular mating contacts 22 and a circular central mating contact 23. The contact pins 21 are connected to the electrical leads 9 and the mating contacts 22,23 to the electrical leads 24. The contact pins are arranged at different radial distance from the central axis, so that the electrical contact is independent of the mutual rotational position of knob 6 and lock cylinder 1 given.
