The blocking element is attached by means of the motor (17). The motor can be controlled with the data located on the key.

Description

The invention relates to an electromechanical rotary lock cylinder according to the preamble of claim 1.

Electro-mechanical lock cylinder of the type mentioned have long been known. They have the advantage that increased security is possible through electronically secured user recognition. With this user recognition is achieved that only by introducing a predetermined electronic information, the rotor can be operated by the imported key.

An electro-mechanical rotary lock cylinder is for example by the EP 0 712 181 A (AZBE) became known. This has as a blocking element to a blocking pin which is mounted in a cylinder bag and which is connected via an eccentric with an electric motor. By rotating the shaft of the electric motor, the pin can be moved from a first to a second position when the electronic code read by a key inserted in the lock cylinder corresponds to a code stored in a memory of the lock cylinder. To power the electric motor batteries are stored in the cylinder bag. In this rotary lock cylinder, the energy consumption for moving the blocking element or the blocking pin is comparatively high. The batteries must therefore be replaced comparatively frequently. So that the electronic code can be read, a contact element is arranged in the key channel, which contacts the key inserted into the key channel at a front end of the shaft.

By the DE 195 17 728 C (Keso GmbH) has also become known an electro-mechanical rotary lock cylinder of the type mentioned. In this, the blocking element is designed as a bracket which engages in recesses of the rotor. In the cylinder bag an actuator is arranged, which has an electric motor whose shaft is provided with two opposing cams, which engage in the blocking position on the bracket. The strap is released, it can be pushed out of the recesses in the peripheral surface of the cylinder core by the manual force when turning the key inserted into the cylinder core. Improper operation may cause the two cams to jam between the bracket and the cylinder housing, resulting in increased power consumption.

The DE 195 17 704 A (BKS) discloses an electro-mechanical rotary lock cylinder in which the locking element is also designed as a sliding pin. This pin is also coupled via an eccentric with an electric motor. When turning the eccentric, the locking pin is moved. Again, the energy consumption for the operation of the locking element is comparatively high.

The invention has for its object to provide an electro-mechanical rotary lock cylinder of the type mentioned, which is characterized by a much lower energy consumption and can still be produced inexpensively and is functionally reliable.

The object is achieved in a generic rotary lock cylinder according to claim 1. In the inventive rotary lock cylinder, the blocking element is not moved with the actuator, but with a pusher member. The energy for this is applied mechanically when inserting the key shaft in the keyway. The energy for moving the locking element is thus applied by the user mechanically by inserting the key in the keyway. The actuator only serves to fix the blocking element in the closed position.

According to a development of the invention it is provided that the trigger member protrudes in a rear portion of the rotor in the keyway and with the key in the channel introduced key is movable. When inserting the key into the keyway the pusher member is moved shortly before the complete insertion of the key shaft in the engine, for example, down. This allows a very simple and safe operation of the trigger member.

The trigger member according to the invention has a contact element which allows further mechatronic functions, in particular programming the electronics with a programming key and / or a supply of the control device

Further advantageous features emerge from the dependent claims, the following description and the drawings.

The in the FIGS. 2 to 4 shown rotary lock cylinder 1 has a rotor 10 which is mounted in a bore 6 of a stator 5. The rotor 10 has a keyway 11, in accordance with the FIGS. 7a to 7d a shaft 4 of a key 2 is insertable. By holes not shown here in the key shank 4 tumblers, not shown here are classified. These tumblers have core pins and housing pins, which are mounted in slides, not shown here, which in recesses 16 ( Fig. 2 ) of the stator 5 are arranged. With the rotor 10 is a driver not shown here coupled, with a latch of a lock, not shown here is operable. The rotary lock cylinder 1 may be a simple rotary lock cylinder with only one rotor 10 or a double rotary lock cylinder with two rotors 10 and correspondingly two stators 5.

The key 2 can according to the WO 2004/066220 be formed of the applicant. In the key 2 can thus have a control circuit and a transmitting and receiving circuit in a known manner, so that information signals to the control circuit of the rotary lock cylinder 1 can be transmitted. The rotary lock cylinder 1 can be operated "stand alone" or networked.

The stator 5 has a cylinder bag 8 with a rearwardly open recess 12 for receiving a connecting web, not shown here. In the cylinder bag are according to FIG. 3 Holes 40 are provided which receive pins, not shown here, with which said connecting web is connected to the stator 5.

The recess 12 is connected to a further arranged above recess 9, in which the in FIG. 1 shown actuating device 14 is inserted. This serves to actuate a locking element 25 which has two mutually spaced locking pins 32, which are each mounted displaceably in a bore 30 of a guide member 28. The plate-shaped guide element 28 is fastened to a carrier 15. This carrier 15 has a block 27 in which an electric motor 17 is mounted. The electric motor 17 is supplied via lines 41. The guide element 28 is according to the Figures 2 and 3 used in a recess 13 of the stator 5, which is open towards the keyway 11 and also to the recess 9. The two locking pins 32 protrude in a closed position respectively FIG. 3 in a bore 36 of the rotor 10 and lock it thereby. The guide element 28 has an upper surface 29, which is curved according to the lateral surface of the rotor 10.

In the guide member 28, a pusher member 33 is mounted, which has two cams 35 and 42, according to FIG. 2 from below into the keyway 11 protrude. As can be seen, the pusher member 33 projects through a passage 31 of the guide element 28 and protrudes beyond the surface 29. The cam 42, which has a front to a front side 7 of the rotary lock cylinder 1 a smaller distance than the other cam 35 has a surface 34 which is inclined to the direction of movement of the pusher 33 and also to the direction of movement of the locking element 25. The pusher member 33 has on its underside a spring element 43, which is supported in a recess 26 of a plate 23. If the trigger member 33 according to FIG. 2 moved downward in the direction of the arrow 44, the spring element 43 is tensioned. The spring element 43 is here a spiral spring, but can also be any other suitable energy storage element.

The pusher member 33 can be moved by inserting the shaft 4 in the keyway 11 in the direction of the arrow 44 downward. As mentioned, in this case the spring element 43 is tensioned. When inserting the shaft 4 in the keyway 11, the front end of the shaft 4 moves on the inclined surface 34 on the pusher member 33 and moves it as mentioned down. When fully inserted shaft 4, the two cams 35 and 42 are completely outside the rotor 10 and thus outside of the keyway 11. Preferably, the pusher member 33 is disposed in the rear region of the keyway 11, it is thus only operated when the key 2 already is pushed to a large extent in the keyway 11.

The pusher 33 has according to FIG. 1 two laterally projecting arms 45 which are disposed below the guide member 28 and which each engage around a locking pin 32. On the arms 45 each have a spring element 37 is supported, which projects down into a passage 24. At the bottom of the springs 37 are each according to FIG. 3 supported on a mushroom-shaped head 38 of the corresponding locking pin 32. If the pusher member 33 is moved in the direction of the arrow 44 down, the two spring elements 37 are compressed and thus the two pins 32 are stretched. When pressing the trigger member 33 thus the spring element 43 and the two spring elements 37 are tensioned.

The pusher 33 has according to FIG. 8 a band-shaped contact element 51 having an upper contact surface 52 and a lower contact surface 53. The upper The contact surface 52 extends approximately horizontally and is located at the upper end of the pusher 33. The lower contact surface 53 extends downwardly and is arranged so that it can be electronically contacted upon depression of the pusher 33 with a control device 48. The control device 48 consists of a hood-shaped guide plate shown here only schematically, which covers the motor 17 and which is used both on the inside and on the outside. Through an opening 54 projects through an antenna 49, which is inclined as shown to the horizontal and to the in FIG. 2 directed window 55 is directed towards. However, the window 55 is not mandatory.

At the control device 48 are according to FIG. 9 an upper contact tongue 50 and a lower contact tongue 56 are arranged. Upon depression of the pusher member 33 with the key 2, the upper contact tongue 50 is pressed onto the lower contact tongue 56 by the pusher 33. Not necessarily is not the said inclination of the antenna 49th

By the contact of the upper contact tongue 50 with the lower contact tongue 56, the electronics is woken up from a "sleep mode", whereupon the motor 17 is actuated. The controller then immediately falls back into "sleep mode". It is awakened again as soon as the contact between the two contact tongues 50 and 56 is canceled again, whereupon the motor 17 is actuated again. The controller then falls back into the "sleep mode".

The contact element 51 can be electrically contacted with a programming key (not shown here) on the contact surface 52. This makes it possible to use the trigger member 33 for further mechatronic functions. For example, the programming key can be used to program the electronics with regard to authorizations. In order not to load the battery in this case, the electronics can be fed via the programming key. However, the contact element 51 can also be used as a charge contact for an emergency opening when the battery is empty.

With the contact element 51 can thus be made an electrical connection of the programming key and the electronics of the control device 48. Of the Wake-up contact via the two contact tongues 50 and 56 is independent of the connection of the contact element and can in principle be carried out without electrically conductive components.

In the mentioned closed position, the two locking pins 32 are in accordance FIG. 3 each with said head 38 on a slider 20 at. The slider 20 is guided in a slot-shaped recess 21 of the carrier 15. The slider 20 has according FIG. 3 an inclined surface 46. At this surface 46 are the two heads 38 on. The surface 46 is inclined to the longitudinal direction of the two pins 32 so that the slider 20 can be pulled away from the pins 32 without substantial friction. In the in FIG. 3 shown position of the slider 20, the two locking pins 32 can not be moved down. The pins 32 are thus fixed by the slider 20. Thus, the two pins 32 can be moved from the pusher 33 down, the slider 20 is in FIG. 3 shifted with the motor 17 to the left, so that the engagement of the two locking pins 32 is lifted on the surface 46. For this purpose, a comparatively small way is required. To move the slider 20, the motor 17 via a transmission G ( Fig. 1 ) is connected to the plate 23. The gear G has a spindle 18 with an external thread 19, which engages in a corresponding threaded bore 22 of the slider 20. The transmission G can also be another suitable transmission, for example a worm gear or the like. The actuation of the slide 20 can also be done in a different way, for example pneumatically, electromagnetically, hydraulically or with a piezoelectric element. The movement is in the example shown a linear movement, but in principle is also another movement, such as a rotational movement possible. The power consumption for shifting the slider 20 is very small. In one direction of rotation thus the slider 39 is in FIG. 3 moved to the left. Sufficient is already a way in the range of about 1 mm to cancel the fixation of the two locking pins 32. To the slider 39 back into the in FIG. 3 shown position, the spindle 18 is rotated in the other direction accordingly, so that the slider 39 in the in FIG. 3 shown position moves. The gear G is preferably self-locking, so that the slider 39 can not be moved without operating the motor 17.

Based on Figures 5a to 5d, 6a to 6d and 7a to 7d the mode of operation of the inventive rotary lock cylinder 1 will be explained in more detail below.

To operate a lock or the like, the key shank of the key 2 according to the FIGS. 5a, 6a and 7a introduced into the keyway 11. The front end of the key shank 4 in this case moves onto the trigger member 33 and moves it downwards. The two contact elements 50 and 51 touch each other, whereby the electronics is woken up. When inserting the key 2, the code stored in the key 2 is also read and the authorization is checked. The key shank 4 is completely in the keyway 11, the tumblers are arranged and the trigger member 33 is according to the FIGS. 5b, 6b and 7b in the lower position. The slightly longer cam 35 is under tension on a lower narrow side 47 of the shaft 4 at. The two locking pins 32 are still in engagement with the rotor 10, as shown in FIG FIG. 3 is shown. The spring elements 37 and 43 are stretched. The slider 20 is located in the in FIG. 3 shown position and thus the two locking pins 25 are fixed downward. The rotor 10 is thus still locked. At about the same time as the depression of the trigger member 33, the code stored in the handle 3 of the key 2 is checked contactlessly in a control (not shown here) for access authorization. If the access authorization is given and decided that the rotor 10 may be actuated by the inserted key 2, then the actuator or the motor 17 is switched on and the slider 20 is displaced, so that the two locking pins 32 are released. The two heads 38 in this case slide along the inclined surface 46 and are due to the voltage of the two spring elements 37 and 43 immediately moved down so that the engagement of these locking pins 32 on the rotor 10 is released. Due to the inclination of the surface 46, the locking pins 25 act with a horizontal force component on the slider 20, which supports the movement of the slider 20 and correspondingly reduces the power consumption. The rotor 10 is now free and can be rotated. The Figures 5c, 6c and 7c show the state in which the slider 20 is retracted and the two locking pins 32 are in the lower position.

If the key 2 is deducted from the rotary lock cylinder 1, the presser member 33 moves by the action of the tensioned spring 43 back up into the in the Figures 5d, 6d and 7d shown position. The two cams 35 and 42 thus protrude again into the keyway 11. The two arms 45 are according to FIG. 1 on the underside of the guide member 28, whereby the movement of the pusher member 33 is limited upwards. By the tensioned springs 37 are approximately simultaneously with the pusher 33, the two locking pins 32 upwards in the in FIG. 1 shown position moves. The contact between the two contact elements 50 and 51 is canceled and thereby the electronics is woken up and the motor 17 is activated. Now, the slider 20 is returned by the motor 17 in the in FIG. 3 shown position moves in which the two locking pins 32 are locked. The rotor 10 is thus in turn blocked by the two locking pins 32. Upon further removal of the key 2, the other spring-loaded tumblers are now moved into the blocking position. The electronics are again in "sleep mode" and the rotary lock cylinder 1 ready for further operation.

In the above-mentioned operation, the slider 20 is retracted only when the pusher member 33 is in the lower position and the spring members 37 and 43 are thus tensioned. This is readily accomplished by delaying the electronics by reading in and checking the code and operating the motor 17. Basically, it is possible to minimize this delay such that the slider 20 is about to actuate the pusher 33 or substantially simultaneously the slider 20 is withdrawn.

The FIGS. 10 to 18 show a rotary lock cylinder 1 'with an actuator 60 according to an alternative embodiment. The actuator 60 operates substantially the same as the actuator 14. Instead of the slider 20 here is a locking lever 68 is provided. Two locking pins 64 engage in a working position in the rotor 10 and are locked by the locking lever 68 in this position. If the authorized key 2 is inserted into the rotary locking cylinder 1 ', a motor 78 is switched on and released by the motor of the locking lever 68. The biased locking pin 64 can now be moved by fully inserting the key 2 in a position in which the rotor 10 is no longer locked. It is also essential in this embodiment that the locking pin 64 by inserting the Key 2 are moved into the rotary lock cylinder 1 'in the unlocked position. The motor 78 has only the task of releasing the locking lever 68 and finally lock again. This is possible with a very small amount of energy, so that the energy source, such as a battery can be spared. In addition, jamming can be avoided. The actuating device 60 will be described in more detail below.

The actuator 60 has a housing 76 which is fixedly disposed in the rotor 10. On the housing 76, an upper housing part 61 is placed and fixed on the housing 76 with a fastening screw 62 and 79. In the housing 76 of the motor 78 and the locking lever 68 are mounted. The upper housing part 1 serves to support the two locking pins 64 and the trigger member 63.

To the rotor of the motor 78, a worm 77 is connected, which can be rotated with the motor 78 in the positive and negative directions of rotation about the motor axis. The worm 77 is engaged with a toothing 80 of a toothed segment 71. By turning the worm 77, the sector gear 71 can be pivoted about two bearing pins 69 between two positions.

The toothed segment 71 has laterally an integrally formed bearing pin 72, with which it is pivotally mounted in the housing 76. Opposite this bearing pin 72, a locking member 73 is arranged, which cooperates with a ratchet lever 74. The ratchet lever 74 is pivotally mounted about a pivot axis 81 on the locking lever 68. As the FIGS. 13 and 14 show the ratchet lever 74 by means of a leaf spring 75 in the in FIG. 13 held position shown. The leaf spring 75 biases the ratchet lever 74 in the FIG. 13 counterclockwise with a lever arm 85 against a web 83. The ratchet lever 74 is as shown angular and has on an upwardly projecting lever arm 86, a surface 84 against which said locking member 73 abuts. In the in FIG. 12 shown position, the ratchet lever 74 can not be moved upwards, since it is present at the locking member 73. In the FIG. 12 Therefore, the locking lever 68 can not be pivoted counterclockwise about the two bearing pin 69. This has to Result that the two locking pins 64 from the in FIG. 12 shown position can not be moved down.

The two locking pins 64 have at a lower end a foot 66 which engages in a recess 70 of the locking lever 68, such as the FIG. 12 shows. The recesses 70 are each directly below one of the two bearing pins 69. In the blocking position of the rotary lock cylinder 1 ', as explained above, the locking lever 68 can not be pivoted about the two bearing pins 69. The two locking pins 64 are therefore fixed in the locked position. By turning the screw 77, the sector gear 71 can now be pivoted about the bearing pin 72 so that the locking member 73 no longer locks the ratchet lever 74 and the locking lever 68 in FIG. 12 can be pivoted counterclockwise about the two bearing pin 69. The two locking pins 64 are thus no longer fixed down.

On each locking pin 64, a compression spring 65 is placed, which is loaded with the pusher 63. For this purpose, the pusher 63 has according to FIG. 10 two arms 87, each receiving a locking pin 64. If the trigger member 63 is moved downwards by the key 2, the two compression springs 65 are tensioned. Accordingly, the two locking pins 64 are clamped down against the locking lever 68. At the same time, the compression spring 67 is tensioned, which is supported on the housing 76.

The mode of operation of the device according to the invention will be described below in particular with reference to FIG FIGS. 15 to 18 explained in more detail.

The Figures 15a, 15b and 15c show the rotary lock cylinder 1 'in the locked position. The two locking pins 64 each engage with an upper end in a recess of the rotor 10 and lock it. The usual tumblers, which also lock the rotor 10, are not shown here. These tumblers are designed as usual and can be classified by not shown here control bores in the shaft 4 of the key 2. To release the rotor 10, according to the FIGS. 15a and 15b the shaft 4 of the key 2 is inserted into the keyway. Now reaches the front end of the shaft 4 a front up in the Key channel protruding part 88 ( Fig. 16c ), and is pushed further, the pusher 63 is moved down and the springs 65 and 67 tensioned. However, the locking pins 64 remain in the locked position. At about the same time, the controller checks without contact the code of the key 2. If the key 2 authorized, the motor 78 is turned on and by rotation of the screw 77, the toothed segment 71 to the bearing pin 72 in the in FIG. 17c shown pivoted position. As can be seen, is now the locking member 73 outside the range of the surface 84 of the ratchet lever 74. The key 2 can now be fully inserted into the keyway and accordingly, the two locking pin 64 and the pusher 63 can be moved further down. The locking lever 68 is in this case in the in FIG. 17c shown pivoted position. The two feet 66 are now on the housing 76. By this pivotal movement of the locking lever 68, the leaf spring 75 is tensioned. Since the locking pin 64 no longer engage in the rotor 10, this can be rotated, since the other tumblers, not shown, are arranged. Since the rotor 10 is released, the lock can be opened.

If the key 2 according to Figures 18a, 18b and 18c withdrawn again, the pusher 63 is moved by the spring 67 back to its original position. The leaf spring 75 simultaneously pivots the locking lever 68 back into the in the Figures 12 and 15c shown starting position. The two locking pins 64 are also raised with the movement of the pusher 63 in the locked position. When removing the key 2, the motor 78 is also switched contactless and the screw 77 is rotated counterclockwise, so that the toothed segment 71 is pivoted and the locking member 73 is brought into the locked position. This is again the in FIG. 15c reached shown position in which the rotary lock cylinder 1 'is locked.
