Definitions

• the present invention relates to a locking mechanism for a door according to the preamble of patent claim 1 and an actuating member for a locking mechanism of a door according to the preamble of patent claim 10.
• Such a locking mechanism is generally known as a security cylinder lock (see, for example, Brockhaus der Naturwissenschaften undtechnik, D-Wiesbaden 1972, pages 662 and 663), in which a socket wrench forms the master key with the cylinder core.
• the cylinder core is secured against unauthorized rotation by several pairs of locking pins of different lengths. These adapt to the incisions of the key in such a way that their dividing surfaces coincide with the lateral surface of the cylinder core.
• the cylinder is then unlocked and can be turned.
• Locking mechanism consists of a lock case with a mechanical lock and a door handle as an actuator.
• the lock case has a slot and an electronic control unit with which a punched key card is optically read out and the lock is released when access is authorized.
• the electronic control unit of the lock is connected to a central computer which determines the type of use, the duration of use and the like of a programmed or punched key card.
• the invention is based on the object of improving a locking mechanism and an actuating member for a locking mechanism of the generic type in such a way that simple and safe operation of a door lock is provided which enables electronic control without having to replace existing door locks. It should be possible to achieve an equal or higher security standard, as with the existing electronic door security devices.
• the invention has the great advantage that any locks can be retrofitted in a few simple steps to provide a modern and practical mechanical to obtain door security with a high degree of security, which is particularly suitable for electronic control. Furthermore, it is now irrelevant whether the lock is left-handed or right-handed, because the actuator of the new locking mechanism is suitable for both types of locks.

• an annular groove 11 is provided, in which a locking ring 12 engages.
• a stop ring 13 is fastened on the axis 8 on the side of the support body 9 opposite the end face, so that the support body is axially secured between the locking ring 12 and the stop ring 13.
• the housing 2 consists of a circular cylinder 14 and a circular end cover 15, which is shown by dashed lines Longitudinal bores 16 in the support body 9 passing screws 17 are attached to the circular cylinder 14.
• the longitudinal bores 16 are widened stepwise on the side facing the end cover 15, into which extensions 18 corresponding pins 19 of the end cover 15 with internal threads 20 provided for the screws 17 fit.
• a sleeve 24 is embedded, into which a pin 25 is screwed.
• a small cam 26 is formed, to which a spindle 27 of an electric motor 28 is axially opposite at a distance.
• the cam 26 is provided with an external thread 29, onto which a spiral spring 30 connected to the spindle 27 is screwed.
• a radially continuous bore 32 is provided on the axis 8, through which a driver bolt 33 extends and is arranged symmetrically to the axis 8. In the arrangement shown, the pin 25 engages with this driving pin 33.
• the end cover 15 is provided with a central circular opening 34, which has an annular groove 35 on the inside, in which a spherical cap-like contact disk 36 is embedded. It is guided by an insulation ring 37 which fits into the annular groove 35.
• a circular printed circuit board 38 having electrical conductor tracks is provided with the pins 19 corresponding holes and thus clamped against the inner end face of the end cover 15. Between the contact disk 36 and the circular printed circuit board 38 there is a spring element 39 which at the same time ensures the electrical contact of the contact disk 36 with the printed circuit board 38.
• the support body 9 is shown in a view from the front and in Figure 2b from the back. Furthermore, the bearing plate 3 is shown in plan view in FIG. 3 and the cross sections through the support body 9 along the line A-A or along the line B-B in FIG. 2a are shown in FIGS. 4a and 4b.
• FIGS. 4a and 4b The further reference numerals in these figures are explained with reference to the embodiments in FIGS.
• the rotary knob 1 In the closed state of the door 4, the rotary knob 1 can be freely rotated on the round axis 8, ie the spindle 27 of the electric motor 28 is in a position retracted against the end face of the rotary knob 1, so that the pin 25 is disengaged from the driver bolt 33 is.
• the spiral spring 30 functions as a tension spring for transmitting the tensile forces to the pin 25.
• the contact disk 36 lies against the connection cover 15 electrically connected to the bearing plate 3 and in this way is constantly electrically connected to ground, ie serves as transient suppression the contact disk 36, as prescribed in the relevant standard IEC 801. Details on this can be found, for example, in the article “EMC does not Problem be "in” Electronics ", Issue 4, 1992, pages 104-109.
• the contact disk 36 can be activated by an electronic key (not shown here), available under the name "CABLOCK” (registered trademark) from the company CABCOM Engineering Rolf Jäger in CH-8181 Höri.
• the contact disk 36 is preferably a "Touch Memory Probe DS9092” from DALLAS SEMICONDUCTOR, Dallas, Texas (USA), and the key contains an electronic circuit called “Touch Memory DS199x” from this company.
• the electric motor 28 drives the spindle 27 in the direction against the Door 4 so that the pin 25 can come into engagement with the driving pin 33 via the spiral spring 30 as a compression spring. If the driving pin 33 is exactly in the direction of displacement, so that the pin 25 comes to stand on the driving pin 33, the spiral spring 30 causes the pin 25 to jump past the driving pin 33 with a slight rotation of the rotary knob 1, even if the spindle 27 is already in the end position. In this sense, the spiral spring 30 acts as a force storage element during the reciprocating movement of the pin 25.
• the rotary knob 1 described above is both suitable for door locks with a left as well as a right turn.
• FIG. 5 Another variant of the rotary knob 1 is now shown in FIG. 5, in which the pin 25 engages with a receptacle 41 in the end shield 3 (see also FIG. 3).
• the receptacle 41 is designed as an oval, conically tapering opening, which still allows a slight rotation of the engaged pin 25 of approximately 5 * .
• the shaft 7 is also formed in the area of the rotary knob 1 square, and the support body 9 with the central bore 10 formed in the square is fixedly attached to the shaft 7.
• a hook-shaped wire pin 44 is provided which engages in the pin 25 and can be pushed through the end cover 15. In this way, it is easy to check from a distance whether the rotary knob 1 is in the locked state or whether the shaft 7 can be rotated and the door lock is thus released.
• a sensor or a switch can also be provided on the circuit board 38, which is connected via the conductor tracks of the circuit board 38 to the electronic circuit of the circuit board 40 and to a light-emitting diode in the end cover 15, and which controls the position of the pin 25 checked.
• the function of this rotary knob 1 is similar to that described above with reference to the embodiment in FIG. 1.

• FIG. 6 shows a further variant with two knobs 1 and 1 'of identical design.
• the contact disk 36 is located in the outside rotary knob 1 'and the lock can be moved back and forth.
• Ren pin 25 is provided in the opposite, arranged on the inside of the door 4 knob 1.
• the shaft 7 is provided with a small through bore or milling 47, from which two cylindrical long pins 48 protrude on both sides. which are pressed apart by a thin spiral spring 49. If these pins 48 are too long for a given door thickness, they can easily be cut to size on the spot.
• the printed circuit board 38 of the inner rotary knob 1 has an electrical plug contact or the like at a corresponding point.
• the supporting body 9 is not held in place with stud screws but with spring screws 50 having a spring-loaded ball in a locking position defined by spherical recesses 51 in the shaft 7.

It is understood by the person skilled in the art that the housing 2 of the rotary knobs 1 or 1 'described above does not necessarily have to be circular cylindrical, but other suitable shapes in the manner of a hollow body can also be used for this purpose.
• the electronic operation of the locking mechanism increases security, since the access coding for the contact disk 36 can be reprogrammed at any time by means of special higher-level programming devices. There is also the option of only granting access authorization for certain periods and / or for certain people (i.e. holders of a specific electronic key).
