Description

[0001] The invention relates to a method for determining the position of a rotary element relative to a housing of a key-operating device for turning a key in a lock of a door or the like, which includes an operating element, in particular a locking cylinder, and an actuator arranged in the housing that drives the rotary element in conjunction with the key or an adapter element, and a transmission for mechanically connecting the actuator to the rotary element, wherein the key or the adapter element is arranged in a key or adapter element receptacle. The invention further relates to a key-operating device for turning a key in a lock of a door or the like, which includes an operating element, in particular a locking cylinder.for carrying out a method according to the invention, with a housing in which an actuator, a rotary element which can be driven by the actuator to rotate in order to connect to the key or the adapter element and a gearbox for mechanically connecting the actuator to the rotary element are arranged, wherein the key or the adapter element is arranged in a key or adapter element receptacle.

[0002] Key-operating devices for turning a key in a lock having a locking cylinder of a door or the like are sufficiently known from the prior art.

[0003] Such a key-operated device is known, for example, from DE 10 2004 021 704 B3. The essential feature there is the design of a coupling device by means of which the actuator, with which the gearbox of the key-operated device is driven, can be engaged and disengaged. The actuator is only coupled to the gearbox when the key is to be turned electrically. Otherwise, the actuator is disengaged, which facilitates manual operation.

[0004] Another key-operated device is known from EP 3 000 953 B1. In this patent, it is specifically provided that the gearbox is arranged on the housing of the key-operated device via an intermediate buffer assembly. The buffer assembly is intended to counteract noise and vibration transmission and thus serves to dampen noise and vibration.

[0005] Furthermore, a key actuation device is known from US 2022 / 381064 A1 in which the key adapter element is rotated to a key removal / key insertion position.

[0006] With key-operated locking devices of this type, the problem arises that the key can be unintentionally or even manipulatively partially removed from the lock cylinder. This occurs, for example, by pulling on a handle connected to the key, particularly the key head. If a certain amount of pressure can be applied to the key head, it is possible to use the handle to slightly move the key out of the lock cylinder, preventing it from turning and thus rendering the lock impossible to open or close. The same applies to manipulatively knocking the key out of the lock cylinder. It should be noted that standard lock cylinders have spring-loaded locking pins located within the cylinder housing.Inserting the key with the correct code into the lock cylinder displaces these locking pins into a position where a cylinder rotor can be rotated within the cylinder housing by the key. This rotation also engages a locking cam, which acts on corresponding elements within the lock to, for example, move a latch and / or bolt from the locked to the unlocked position, or vice versa.

[0007] Based on this state of the art, the invention lies in the Task The basis is a method for determining the position of a rotary element in a key actuation device or for further developing a key actuation device in such a way that unintentional or manipulative removal from the locking cylinder can be avoided, whereby a method that is as cost-effective as possible is provided.

[0008] The SolutionThis problem is addressed in a method according to the invention, in that at least one position of the key or adapter element receptacle relative to the housing is determined by means of a device with a first element and a second element corresponding to the first element, by moving the second element, which is movable relative to the first element and arranged directly or indirectly at the key or adapter element receptacle, past the first element, which is fixedly arranged in the housing, and in that the at least one position represents a specific arrangement of the two elements, in particular a position of the two elements opposite each other, and in this position an, in particular electromechanical and / or electromagnetic, signal is generated, which signal is used to control the actuator in such a way thatthat the actuator is not deactivated in this position when in an activated state, or is activated in this position when in a deactivated state, so that the actuator remains activated or is activated in the specified position, so that a position of the key or adapter element receptacle in the specified position, which allows the key or adapter element to be pulled out of the actuating element, in particular the locking cylinder, is prevented by activation or maintenance of the activation of the actuator.

[0009] This method allows a key-operated device to be handled in a simple manner such that the position of the key or adapter element is detected in at least one, possibly two, unique positions and used to activate or maintain the activation of the actuator, as described below.

[0010] Further developments of the inventive method provide that the corresponding elements are configured as a combination of Hall sensors and magnets and / or a combination of microswitches and triggers. These are electrotechnical or electromechanical components that enable unambiguous signal acquisition.

[0011] Furthermore, it is provided that the first elements arranged on a circular path, in particular the Hall sensors, are arranged at certain angular distances to each other, and that the second elements arranged on a circular path, in particular the magnets, are arranged at certain angular distances to each other, and that the angular distances are the same on one of the two and / or the two circular paths.

[0012] In the method according to the invention, it is further provided that the rotating element with two magnets or microswitches, which are in particular arranged on a circular path offset from each other by 180°, is guided past two Hall sensors or triggers, which are arranged stationary on a circular path in the housing and preferably offset from each other by 180°, so that one unique or two unique position determinations of the rotating element are possible.

[0013] Finally, according to the inventive method, the key or adapter element receptacle is rotated out of position by the actuator when it reaches a position that allows the key or adapter element to be moved out of the actuating element, in particular the locking cylinder.

[0014] To SolutionThe objective of a key actuation device according to the invention is that a device for determining the position of the key or adapter element receptacle in an angular position relative to the actuating element, in particular the locking cylinder, and a control device for activating the actuator are provided, wherein the device for determining the position has two corresponding elements, of which a first element is fixed to the housing and a second element, movable relative to the first element, is arranged on the rotating element or on the key or adapter element receptacle, so that the key or adapter element receptacle is rotated out of or past a position that allows the key or adapter element to be moved out of the actuating element, in particular the locking cylinder, by the actuator.

[0015] According to the invention, a position-determining device is used to determine the position of the key or adapter element receptacle. This device detects the angular position relative to the lock cylinder. It is known that a key can only be removed from the lock cylinder in one unambiguous position relative to the cylinder. However, lock cylinders are also known in which two unambiguous positions are possible for removing the key. If the lock cylinder is in a different angular position, the key cannot be pulled or driven out.Accordingly, the device for determining the position of the key or adapter element receptacle detects only these unique positions. For this purpose, the device comprises two corresponding elements: a first element is fixed to the housing, and a second element, movable relative to the first, is located on the rotating element or the key or adapter element receptacle. A signal is generated when the two elements reach a specific position, which is then processed, for example, to activate the actuator in a control unit. Thus, when the control unit receives a signal indicating a specific position of the two elements of the device relative to each other, the control unit activates the actuator.This actuation of the actuator switches the actuator on and, via the gearbox, rotates the rotary element by a certain angle into a position of the key or adapter element in the actuating element, in particular in the lock cylinder, in which it is not possible to move the key or adapter element out of the actuating element, in particular the lock cylinder.

[0016] Alternatively, it can be provided that deactivation of the actuator upon reaching a specific position is prevented. The actuator, which is in an active operating state, cannot thus be deactivated via the control device if this would cause the two elements to be in the specific position. The actuator then rotates further by an angular value that excludes this specific position of the two elements, the angular value preferably being of a magnitude that excludes the signal.

[0017] If, however, the two elements reach a position in which the signal is generated, the control device can activate the actuator to move the elements into a position that corresponds to a position of the key or adapter element receptacle relative to the actuating element, in particular the locking cylinder, in which the key or adapter element arranged in the key or adapter element receptacle cannot be moved out of the actuating element, in particular the locking cylinder.

[0018] Preferably, the corresponding elements are electromagnetic and / or electromechanical. According to a further feature of the invention, the corresponding elements are configured as a combination of Hall sensors and magnets and / or as a combination of microswitches and triggers. In both cases, precise positions of the key or adapter element receptacle can be detected, for example, by activating the microswitch when the trigger is reached. If the microswitch remains energized, the control unit receives a corresponding signal and activates the actuator by supplying power to the actuator from a power source. The same applies to the combination of a Hall sensor and a magnet. If the magnet is moved past a Hall sensor, no activation occurs.If the magnet remains in a precise position relative to the Hall sensor, this signal is used to activate the actuator via the control unit. When the key or adapter element is rotated, the magnet moves away from the Hall sensor, and no further signal is sent to the control unit. The actuator is then switched off.

[0019] Preferably, the rotating element has receptacles arranged around its circumference at particularly uniform intervals, which can be fitted with second elements, in particular magnets. Furthermore, it is provided that the corresponding first elements, in particular the Hall sensors, are arranged on a circuit board fixed in the housing such that the arrangement of the first elements is on a circular path that essentially coincides with a circular path on which the receptacles are arranged.

[0020] In this configuration, the elements can also be used for other signals. For example, such an arrangement can be used to determine the direction of rotation, the rotational speed, and the angular position of the rotating element. This information can also be processed in the control unit, for example, to detect the rotation of the rotating element towards a stop, which might be defined by the latch and / or bolt in the lock. In this case, it may be necessary to switch off the actuator to prevent increased current consumption by the actuator when attempting to rotate past the stop.

[0021] According to a further feature of the invention, the number of first elements, in particular the Hall sensors, is equal to the number of second elements, in particular the magnets, whereby at least two positions of the key or adapter element receptacle can be detected. It should be noted that a conventional key can only be removed from a lock cylinder in one position. In the opposite position, i.e., rotated by 180°, removal of the key from the lock cylinder is not possible. Nevertheless, it is of course useful to also detect this position in order to determine that activation of the actuator is not required in this second position. This design serves to improve the detection of the one position in which activation of the actuator is necessary.

[0022] Furthermore, there are also lock cylinders known that are operated with keys which can be pulled out of the lock cylinder in two positions, namely positions rotated 180° apart. With these lock cylinders, it is also advantageous to uniquely determine the corresponding positions and, if necessary, to activate the actuator via the control unit when these positions are reached.

[0023] Preferably, the rotary element comprises two magnets or microswitches, preferably arranged on a circular path offset from each other by 180°, and two Hall sensors or triggers are arranged stationary on a circular path within the housing, preferably also offset from each other by 180°. This design allows the key-operating device to be used with both a single-position key removal lock cylinder and a two-position key removal lock cylinder, thus enabling the use of a single, identical key-operating device for both different lock cylinders, eliminating the need to stock separate key-operating devices for each.

[0024] Finally, regarding the key-operating device, it is provided that the second element, which is movable relative to the first element, is arranged on a gear wheel of the rotating element. The gear wheel is particularly suitable for receiving the first element because it can be arranged externally on the rotating element and thus forms an external surface on the rotating element which is suitable for receiving the first element and which moves past a stationary second element.

[0025] Further features and advantages of the invention will become apparent from the following description of the accompanying drawing. The drawing shows: Fig. 1 the housing of a key-operated device in a first view; Fig. 2 the housing of a key-operated device in three further views; Figs. 3 to 7 views of the key-operated device looking at the internal elements; Fig. 8 a view of a key-operated device looking at a rotary element and a locking cylinder; Fig. 9 the key-operated device and locking cylinder in a cross-section looking at a key; Fig. 10 the rotary element in a top view with a key; Fig. 11 a circuit board with first elements; Fig. 12 the rotary element with receptacles and second elements; Fig. 13 a side view of the rotary element together with the circuit board; Fig. 14 a view of an adapter connecting the housing to the locking cylinder; Fig. 15 a view of the adapter without the housing; Fig. 16 another view of the adapter; Fig.17 Another embodiment of the adapter with an opening for receiving modules and an adhesive device; Figs. 18 and 19 Further views of the adapter; Fig. 20 Modules for the adapter in various versions; Fig. 21 An adapter with a Euro module; Fig. 22 An adapter with a UK module; Fig. 23 An adapter with a Swiss module; Fig. 24 A first view of an adapter with a Scandinavian module and mounted housing; Fig. 25 A second view of the adapter with the Scandinavian module according to Fig. 25.

[0026] Fig. 1 Figure 1 shows a key actuation device 1 according to the invention in a first view. External elements of the key actuation device 1 are visible. In particular, a housing 2 and an adapter 5 for mounting on a lock cylinder (not shown) are visible. Figure 1(shown), a rotary dial 4 and a control surface 3 as part of the housing 2.

[0027] Such a key operating device 1 is usually mounted on the inside of a house or apartment on a locking cylinder 16, for example in a door or the like, wherein the locking cylinder 16 cooperates with a lock (not shown in detail) to operate a latch and / or a bolt of the lock.

[0028] The key operating device 1 encloses a key 17 inserted into the lock cylinder 16 (as will also be shown below). Figs. 9 and 10(as can be seen). The key 17 can be operated, for example, by means of the rotary knob 4 or via an actuator 6 that can be controlled via the operating surface 3. For this purpose, the operating surface 3 has, for example, an activation element 65. The opening and closing of the locking cylinder 16 or the lock using the key 17 located in the key operating device 1 can therefore be carried out mechanically by turning the rotary knob 4 or electromechanically by means of the activation element 65 by controlling the actuator 6.

[0029] Instead of the key 17, an adapter element may also be provided which connects a key-like element inserted into the lock cylinder or a comparable actuating element directly or indirectly to the rotary wheel 4 in a rotationally fixed manner.

[0030] In one embodiment, the activation element 65 is designed in the form of two pushbuttons 66. One pushbutton 66 can be used to open and the other pushbutton 66 to close the lock.

[0031] Fig. 2Figure 1 shows a front view, a side view, and a bottom view of the key-operated device 1. The front view refers to the side that, when mounted on a surface (e.g., a door leaf or a rosette), faces the user. The front view shows that, in this embodiment, the rotary knob 4 has a circular base. It also shows that the housing 2 has a U-shaped base. The side view reveals that the operating surface 3 is not flush with the surface to which the rotary knob 4 is attached, but rather projects beyond this surface, forming a kind of protrusion on the housing 2. As can be seen in the bottom view of the key-operated device 1, the rotary knob 4 extends slightly beyond the protrusion of the operating surface 3 on the housing 2.

[0032] The Figs. 3 to 7Views through the key actuation device 1 show further essential elements of the key actuation device 1 located inside the key actuation device 1.

[0033] In Fig. 3 It can be seen that the externally arranged rotary wheel 4 is non-rotatably connected to and interacts with an internally located rotating element 7. This rotating element 7 is connected via its toothed ring 31 to an output pinion 8 of the actuator 6. The actuator 6 can be, for example, an electric motor, in particular a DC motor. The actuator 6 is in turn connected to a power source 9, for example, batteries or accumulators. The rotating element 7, or rather the toothed ring 31 arranged on the rotating element 7, together with the output pinion 8, forms a gearbox 13 driven by the actuator 6. The actuator 6 is thus permanently mechanically coupled to the rotating element 7 via a gearbox 13.

[0034] The rotating element 7 can be equipped with a device for adjusting the force required to rotate the rotating element 7. This device can, in particular, serve as a child safety lock. The device can include an activation element 65 and an electrical and / or mechanical lock that can be activated or deactivated via the activation element 65. One embodiment provides that the actuator 6 is designed as a DC motor and the electrical lock as a short-circuit brake. The mechanical lock can be designed as a friction brake acting against the rotating element 7. The friction brake is preferably electrically activatable. The adjustment of the force required to rotate the rotating element 7 can be configured to activate and / or deactivate the activation element 65 in a time-dependent and / or actuation-dependent manner. Actuation-dependent activation can be effected by a specific key combination, e.g.,...B. simultaneous pressing of the two buttons 66. The time-dependent activation can be carried out via a specific pressing duration, e.g. pressing one button 66 for 5 seconds.

[0035] The setting of the device can be indicated by a visual signal, for example by an LED.

[0036] Fig. 4 The figure shows a view through the back of the key-operating device 1. "Back" means the side that, in the case of installation, rests against the mounting surface, e.g., a door leaf. Visible are, firstly, guides 10, 11 for receiving fastening elements 43, 44. In one embodiment, these serve to fasten the adapter 5 to the locking cylinder 16. Secondly, the batteries 47 of the power source 9 are visible. The power source 9 can also be electrically connected to the device for adjusting the force required to rotate the rotary element 7.

[0037] Fig. 5shows a view through the front of the key actuation device 1.

[0038] Fig. 6 Figure 1 shows a side view of the key-operating device 1 with a view through to internal elements. The rotary knob 4 is again visible, located outside the housing 2 and non-rotatably connected to the rotating element 7 inside the housing 2 of the key-operating device 1. For this purpose, the rotary knob 4 is connected to the rotating element 7 by means of a shaft-hub connection 12, which extends from the rotary knob 4 into the housing 2 on one side and from the rotating element 7 outside the housing 2 on the other. The key-operating device 1 can be manually operated via the rotary knob 4, which acts like a doorknob, to move a latch and / or bolt of a lock (not shown) in a door.

[0039] In Fig. 7The rotary knob 4 and the rotating element 7 are visible, connected by means of the shaft-hub connection 12. A circuit board 15 is arranged in the housing 2 between the rotary knob 4 and the rotating element 7. The adapter 5 is also visible, which is connected to the housing 2 by means of detent elements 14. A guide 10 for a screw is also visible.

[0040] Fig. 8 Figure 1 shows the key actuating device 1 with rotary wheel 4 and rotary element 7, wherein the key actuating device 1 is mounted on a locking cylinder 16.

[0041] Fig. 9Figure 1 shows the key-operating device 1 and the lock cylinder 16 in a cross-sectional view, with a key 17 inserted in the lock cylinder 16 and held in a receptacle 18 of the rotary element 7. The shaft-hub connection 12 between the rotary wheel 4 and the rotary element 7 is visible, with a retaining screw 19 additionally provided to connect the rotary wheel 4 and the rotary element 7. In the illustrated embodiment, the rotary element 7 is cup-shaped and essentially closed in the direction of the rotary wheel 4. In the direction of the lock cylinder 16, the rotary element 7 is essentially open. An internal circumferential wall 21 provides a space 22. The key 17 is held in this space 22, which forms a key or adapter element receptacle 27. The rotary element 7 also has a projection extending into the space 22.This projection is designed as a circumferential groove 20 in space 22 and serves, on the one hand, to reinforce the rotating element 7 and, on the other hand, allows the key 17 with its key head 23 to rest against this projection or groove 20, so that the key 17 is pushed or held, depending on the key head 23, over the rotating element 7 towards the locking cylinder 16. The key 17 is shown here in a position that is actually undesirable, namely that the receptacle 18, and thus the key 17, is positioned in such a way that the key 17 could theoretically be moved slightly out of the locking cylinder 16 unintentionally, so that rotation of a roller in the locking cylinder 16 would no longer be possible. Therefore, means for determining the position are provided, as well as means to fix the key 17 in a position that can prevent the key from being moved out of the locking cylinder in the aforementioned manner.The means for determining position consist of stationary first elements 33, in particular Hall sensors 34, and second elements 37, in particular magnets 38, which are movable relative to the first elements 33. When the magnets 38 are moved past the Hall sensors 34, signals or impulses are triggered that allow conclusions to be drawn about the position of the magnets 38 and thus about the position of the key 17. If, during position determination, a position is detected at which the key 17 could theoretically be moved slightly out of the lock cylinder 16, an evaluation unit triggers the activation of the inactive actuator 6 or prevents the deactivation of the active actuator 6, so that the actuator 6 rotates the rotary element 7 by an angle sufficient to prevent the key 17 from being moved out of the lock cylinder unintentionally. Reference is also made to the following in this regard: Figs. 11 to 13 referred.

[0042] In this context, "non-active actuator" means a stationary and therefore not energized actuator, while an "active actuator" is energized and thus performs a rotation as intended.

[0043] Further details of the key or adapter element receptacle 27 for the key 17 in the rotary element 7 are from the Fig. 10 recognizable.

[0044] Fig. 10Figure 1 shows a detailed view of the rotary element 7 arranged in the housing 2, with the key or adapter element receptacle 27 and the key 17 held therein. Among other things, a circumferential wall 21 of the rotary element 7 is visible. This wall 21 forms an outer surface 32 of the rotary element 7. The rotary element 7 serves to rotate the key 17 to open or close the lock. In the illustrated embodiment, the outer surface 32 corresponds to the surface of a cylinder. The rotary element 7 has a toothed ring 31 in the area of ​​the outer surface 32. This toothed ring 31 is rotationally fixed and integrally connected to the rotary element 7. As described above, the toothed ring 31 meshes with the output pinion 8 of the transmission 13.

[0045] In Fig. 10It can also be seen that the rotating element 7 has two receptacles 18 and 24 for a part of the key 17, in particular the key head 23 or an adapter element. The first receptacle 18 and the second receptacle 24 are formed within the space 22 defined by the circumferential wall 21 and are perpendicular to each other. The receptacles 18 and 24 have a common area 28 centrally located, which is essentially circular. The first receptacle 18 and the second receptacle 24 each have two sub-areas 25 and 26, which are arranged on both sides of the common area 28. Two sub-areas 25, 26 and the common area 28 together form a receptacle 18, 24. The common area 28 divides the first receptacle 18 and the second receptacle 24 into two sub-areas 25 and 26, respectively.Furthermore, the two sub-areas 25 and 26 of the first recording 18 and the second recording 24 extend preferably radially from the common area 28 in the rotating element 7.

[0046] The receptacles 18 and 24 are each defined by two parallel and spaced-apart walls 29. The distance between the walls 29 corresponds essentially to the typical material thickness of the key head 23 or the adapter element, so that the key head 23 or the adapter element is held in the receptacle without play. The walls 29 may exhibit slight elasticity to compensate for different material thicknesses of the key heads 23 or the adapter elements.

[0047] If the common area 28 and the circumferential wall 21 are circular, the common area forms an inner circle interrupted by the sub-areas 25 and 26, and the circumferential wall 21 forms an outer circle. The walls 29 of the first receptacle 18 and the second receptacle 24 preferably terminate flush with a free edge region 30 of the circumferential wall 21 of the rotating element 7. The receptacles 18 and 24 thus extend over the full inner diameter of the circumferential wall 21. A part of the key 17, in particular the key head 23 or the adapter element, engages in the two sub-areas 25 and 26 of the first receptacle 18 or the second receptacle 24.

[0048] The Figs. 11, 12 and 13 show components of a device with which the position, direction of movement and / or speed of movement of the rotary element 7 relative to the housing 2 can be determined.

[0049] For this purpose, two corresponding elements are provided as components, namely that at least one first element 33 is fixedly arranged in the housing 2 and at least one second element 37, which is movable relative to the first element 33, is arranged on the rotating element 7. The corresponding elements 33 and 37 are preferably electromagnetic and / or electromechanical.

[0050] Particularly preferred are the electromagnetic elements Hall sensors 34 and magnets 38, and the electromechanical elements microswitches and triggers. It is therefore possible to provide either a combination of Hall sensors 34 and magnets 38, or a combination of microswitches and triggers, or to provide microswitches and triggers in addition to the combination of Hall sensors 34 and magnets 38. Thus, there is a purely electromagnetic solution, a purely electromechanical solution, and a solution that represents a combination of electromagnetic and electromechanical solutions.

[0051] The arrangement of the Hall sensors 34 and magnets 38, or the microswitches and triggers, is such that the magnets 38 are presented to the Hall sensors 34 when the rotary element 7 rotates, thereby generating a pulse that is detected in an evaluation unit and analyzed with regard to the rotational movement and / or rotational speed. This allows, for example, the determination of whether the rotary element 7 is approaching a stop limiting its rotation. Such a stop can be defined, for example, by the position of the bolt in the lock and / or the end position of the retracted latch. If the rotary element 7 approaches this stop, the current supply to the actuator 6 can be reduced or switched off based on the evaluated pulse to prevent increased power consumption in the stop position. This evaluation is important when the key-operated device 1 is operated upon activation of the actuator 6.

[0052] Generally, such a key-operated device 1 is located on the inside of a building, attached to a door. The key-operated device 1 can be manually turned from inside the building using the rotary element 7 to turn the key 17 in the lock cylinder 16. The key-operated device 1 is not accessible from outside the building, so it can only be operated by activating the actuator 6. For this purpose, a device for entering a key secret can be provided on the outside of the building. This device can be a keypad for entering a specific combination of numbers or letters, which, if it matches the key secret, connects the actuator 6 to the power source 9, causing the actuator 6 to rotate the key 17.Other methods for transmitting the key secret are possible, such as using a transponder, a biometric reader (e.g., a fingerprint or iris scan), or transmitting the key secret stored on a smartphone or similar device. Wireless transmission of the key secret is preferred.

[0053] In the Fig. 11 In the preferred embodiment shown, first elements 33 are arranged on a circuit board 15. The first elements 33 are the Hall sensors 34. The circuit board 15 with the Hall sensors 34 is fixedly installed in the housing 2 and has bores 35 through which screws 40 are guided, with which the circuit board 15 is positively connected to the housing 2 or other fixed components of the key actuation device 1.

[0054] In Fig. 12A preferred embodiment of the second, movable elements 37 and their arrangement in housing 2 is shown. Fig. 12 The depicted rotating element 7 has receptacles 36 distributed around its circumference, arranged at regular angular intervals from one another. The receptacles 36 are thus arranged at regular intervals on a circular path. The receptacles 36 can be fitted with second elements 37. In the example shown, they are fitted with magnets 38. The second elements 37, in this example the magnets 38, are arranged on the circular path at specific angular intervals from one another. The receptacles 36 can be fitted with magnets 38 depending on the desired function of the key-operating device 1.

[0055] Specifically, in the Fig. 12In the example shown, the rotating element 7 has three magnets 38, each arranged on a circular path offset from one another by 120°. First elements 33, i.e., in this example Hall sensors 34, are also visible, arranged on a circuit board 15 fixed within the housing 2 such that their arrangement on a circular path essentially coincides with the circular path on which the receptacles 36 are arranged. The first elements 33, in particular the Hall sensors 34, as well as the second elements 37, are arranged on the circular path at specific angular intervals. In this particular example, four Hall sensors 34 are fixedly arranged on a circular path within the housing 2, each offset from one another by 90°. Other angular intervals and / or numbers of magnets 38 and / or Hall sensors 34 are possible, and the receptacles 36 allow for simplified assembly, at least by the manufacturer.

[0056] It is essential that the number of first elements 33, in particular the Hall sensors 34, is preferably not equal to the number of second elements 37, in particular the magnets 38. With regard to the angular distances, it is essential that the angular distances of the first elements 33 and the second elements 37 do not coincide, so that a complete overlap of all first elements 33 over all second elements 37 is avoided. For this purpose, the angular distances of the first elements 33 can differ from each other, or the angular distances of the second elements 37 can differ from each other, or the angular distances of the first elements 33 can differ from the angular distances of the second elements 37, or both the angular distances of the first elements 33 can differ from each other and / or the angular distances of the second elements 37 can differ from each other as well as the angular distances of the first elements 33 from the angular distances of the second elements 37.The example shown is one in which the angular distances between the first and second elements 37 are not different (the Hall sensors 34 are offset from each other by 90° and the magnets 38 by each other by 120°), but the angular distances of the first elements 33 differ from those of the second elements 37 due to the arrangement at angular distances of 90° versus 120°. In contrast, it would also be conceivable, for example, to arrange the first magnet 38 at an angular distance of 120° to the second magnet 38 and the second magnet 38 at an angular distance of 60° to the third magnet 38, so that the angular distance from the third magnet 38 to the first magnet 38 would be 180°. This variability allows for the generation of a larger data set, which serves to evaluate the direction of rotation and / or rotational speed or the position of the rotary wheel 4 relative to the housing 2.

[0057] A second embodiment, not shown in the figures, which in particular represents an example of a device for determining the position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, differs from the example described above in that, in this case, the number of first elements 33, i.e., in particular the Hall sensors 34, is equal to the number of second elements 37, in particular the magnets 38, whereby at least two positions of the key or adapter element receptacle 27 can be detected. Alternatively, triggers can be provided as first elements 33 and microswitches as second elements 37. Preferably, the rotary element 7 has two magnets 38 or microswitches, each arranged on a circular path offset from each other by 180°, and two Hall sensors 34 or triggers are arranged stationary on a circular path in the housing 2, each offset from each other by 180°.

[0058] If the rotary element 7 is in a position where the Hall sensor 34 and magnet 38 or microswitch and trigger are exactly opposite each other, and if the position represents a position of the key 17 relative to the lock cylinder in which the key 17 could, for example, be unintentionally moved slightly out of the lock cylinder 16 by a blow, the elements Hall sensor 34 and magnet 38 or microswitch and trigger generate a signal that initiates activation of the actuator 6 via the evaluation unit, so that the actuator 6 of the rotary element 7 is rotated by an angle sufficient to turn the key 17 in the lock cylinder 16 to such an extent that a relative movement of the key 17 in the longitudinal axis direction of the lock cylinder 16 is excluded.

[0059] Fig. 13Figure 1 shows a side view of the circuit board 15, the rotary element 7, and the locking cylinder 16. Here it is particularly clear that the first elements 33, in the form of Hall sensors 34, are fixedly mounted on the circuit board 15. The second elements 37, which are movable relative to the first elements, are the magnets 38. These magnets 38 are mounted on a gear 39 of the rotary element 7. The gear 39 engages with the drive pinion 8. When the rotary element 7 is set into rotation, either by the actuator 6 driving the gearbox 13 or by manually turning the rotary knob 4, the movable elements 37 are moved past the fixed elements 33, triggering a pulse.In the embodiment with the Hall sensors 34 and the magnets 38, an electromagnetic pulse is triggered, but depending on the embodiment, an electromechanical pulse or both an electromechanical and an electromagnetic pulse can also be triggered.

[0060] The operating principle of determining position, direction of movement, or speed of movement using Hall sensors and magnets is based on the fact that Hall sensors, when subjected to a magnetic field perpendicular to their semiconductor layer, produce an output voltage. This output voltage is also called the Hall voltage. Hall sensors typically have four electrodes for this purpose. Of these four electrodes, two are used to supply a current, and two, located orthogonally to the first two, serve as measuring electrodes. The function of the electrodes can be interchanged. This corresponds to a spinning-current operation. The measuring electrodes measure the Hall voltage. Thus, the moment a magnet approaches a Hall sensor, the Hall voltage increases; conversely, when the magnet moves away, the Hall voltage decreases. This increase or decrease is measured by the sensor's position and direction of movement.The voltage drop corresponds to the electromagnetic pulse triggered when a magnet passes by a Hall sensor. Hall sensors can be designed as discrete Hall sensors or as integrated Hall sensors. Unlike discrete Hall sensors, integrated Hall sensors are incorporated into circuits, which may include signal amplification, analog-to-digital conversion, or digital signal processing. Possible shapes include rectangular, butterfly, or cross-shaped.

[0061] According to the exemplary embodiment, the position, direction of movement, and / or speed of movement of the rotating element 7 relative to the housing 2 are determined by arranging a Hall sensor 34 in a fixed position within the housing 2 and moving a magnet 38, movable relative to the Hall sensor 34, past the Hall sensor on the rotating element 7, thereby triggering an electromagnetic pulse. This pulse is then evaluated with respect to the position, direction of movement, and / or speed of movement of the rotating element 7 relative to the housing 2. Beyond position determination, the direction of movement and / or speed of movement of the rotating element 7 can thus be determined continuously or dynamically throughout its rotation. This is particularly simplified when the number of Hall sensors 34 is not equal to the number of magnets 38, or when the angular distances on one or more of the circular paths differ.

[0062] In the exemplary embodiment of a device for determining the position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, the position is determined by a first element 33 being fixedly arranged in the housing 2 and a second element 37, movable relative to the first element 33 and arranged directly or indirectly at the key or adapter element receptacle 27, being moved past the first element 33 and triggering an electromechanical and / or electromagnetic pulse which is evaluated with regard to the position of the key or adapter element receptacle 27 relative to the housing 2, whereby a static comparison of the two elements 33 and 37 is detected as a pulse which represents a specific position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, and generates a signal to activate the actuator 6.so that actuator 6 is moved through a certain angle until elements 33 and 37 are no longer statically opposed to each other and therefore no longer generate any momentum.

[0063] As an adapter element for insertion into the key or adapter element receptacle 27, devices that can be connected to the key or adapter element receptacle 27 in a form-fit or force-fit manner are suitable, such as adapter elements with an end-arranged polygonal head that can be inserted into the key or adapter element receptacle 27.

[0064] Using the described means and methods for determining the position, it is possible to ascertain whether the rotating element 7, and thus the key 17, is in a position that allows the key 17 to be moved out. Typically, positions in which the key 17 can be moved out of the lock cylinder 16 are those in which the key 17 is inserted vertically or horizontally (depending on the design of the lock cylinder and the key) in the lock cylinder 16. Positions in which the key 17 can be moved out are undesirable, as this is equivalent to the key 17 being unintentionally moved a portion of the lock cylinder 16. With the key 17 even slightly moved out of the lock cylinder 16, proper operation could then be prevented, since the rotational movement would be blocked by at least one pin inside the lock cylinder 16 that is not in a release position.If a position is determined that allows the key 17 to be moved out of the lock cylinder, the rotary element 7 is rotated out of this position by the actuator 6. The position can be determined continuously or dynamically during actuation of the key-operating device 1, i.e., throughout the entire rotational movement, or statically, i.e., only after the rotational movement, e.g., an opening or closing operation, has ended. Determining the direction of movement can serve to identify an opening or closing operation. The speed of movement can be determined and adjusted.

[0065] Fig. 14 Figure 1 shows an embodiment of the adapter 5 by means of which the housing 2 can be connected to a door or the like and / or the locking cylinder 16. The adapter 5 is plate-shaped, as is also the case in particular with the Figs. 15 and 16can be removed, and has an opening 41 for at least partial reception of part of the length of a locking cylinder 16.

[0066] In Fig. 14It can also be seen that the lock cylinder 16 is partially received by the adapter 5. The lock cylinder 16 thus protrudes, for example, a few millimeters from the door leaf or the escutcheon. The adapter 5, with its corresponding opening 41, is placed onto this part of the lock cylinder 16, so that the lock cylinder 16 is positively engaged in the opening 41. For a force-fit connection between the adapter 5 and the lock cylinder 16, fastening is provided by means of fasteners in the form of a screw 43 and two spring-loaded bolts 44. Guides 10, 11 are provided in the adapter 5 to receive the screw 43 and the bolts 44; these guides are oriented towards the outer surface 48 of the lock cylinder 16. In the case of installation, the fasteners 43, 44 are therefore in contact with the outer surface 48 or the outer surface of the lock cylinder 16.The adapter 5 can be adjusted and fixed relative to the lock cylinder 16 using the screw 43 and the bolts 44. Additionally, the adapter 5 can be bonded to the door leaf.

[0067] As can be seen from a synthesis of the Figs. 15 to 17 As can be seen, the opening 41 for receiving the locking cylinder 16 has a circular area 46 around which three guides 10, 11 are arranged. The three guides 10, 11 can be seen in particular as Fig. 15A guide 10 for receiving a screw 43 is designed to extend radially to the circular area 46 of the opening 41, according to the embodiment. The two guides 11 for receiving the spring-loaded bolts 44 are preferably oriented secantally. It is particularly preferred that the secantly oriented guides 11 are arranged at equal angular distances to the radially oriented guide 10 and that the angular distance between the secantly oriented guides 11 is smaller than the angular distance between the radially oriented guide 10 and each secantly oriented guide 11. Thus, according to the embodiment, the angle between the radially oriented guide 10 and each of the two secantly oriented guides 11 is larger than the angle between the two secantly oriented guides 11. The angular distance between the radial guide 10 and each of the two secantly oriented guides 11 therefore corresponds, for example, toat an obtuse angle and the angular distance between the two secantial guides 11 is an acute angle. In the illustrated embodiment, the angular distances between the radially oriented guide 10 and each secantly oriented guide 11 are identical.

[0068] In Figs. 15 and 16 The locking elements 14, with which the adapter 5 can be connected to the housing 2, can also be seen.

[0069] As this is particularly evident from Fig. 15 As can be seen, the adapter 5 also has a compartment 45 for installing the power source 9. Batteries 47 and / or accumulators can be accommodated in this compartment 45. Compartment 45 can be adapted to the external contours of standard batteries 47 or accumulators. The batteries 47 are made accessible for replacement by separating the upper housing part 2 from the adapter 5, which is fixed to the lock cylinder 16 and, if applicable, to the door leaf.

[0070] The Fig. 16 It can also be seen that the adapter 5, which serves as a receptacle for the housing 2, has a U-shaped cross-section and, on both sides of the opening 41 for receiving the locking cylinder 16, has holes 49 for receiving screws to fasten the adapter 5 to a door leaf or the like. In particular, two holes 49 can be provided on each side of the opening 41. The distance between the holes 49 on both sides of the opening 41 can, for example, correspond to the distance that commercially available door rosettes have as the hole spacing.

[0071] The Figs. 17 to 19 Figure 1 shows another embodiment of an adapter 5. This adapter 5 is also plate-shaped and U-shaped in cross-section and has an opening 50 for partially accommodating part of the length of the locking cylinder 16. Modules 55, such as those found in [reference to specific product / service], can be inserted into this opening 50. Fig. 20The adapter 5 is prepared for the interchangeable reception of such modules 55. The modules 55 are designed such that they have, on the one hand, an outer contour corresponding to the opening 50 in the adapter 5 and, on the other hand, an opening 50 with an inner contour 56 corresponding to the outer contour of a locking cylinder 16, whereby the modules 55 enable the adapter 5 to be adapted to different locking cylinders 16. As can be seen from the Figs. 17 to 20 As can be seen, the opening 50 in the adapter 5 and thus also the modules 55 are oval in the embodiment shown.

[0072] In Fig. 20Four modules 55 are shown as examples, which can be inserted alternatively into the opening 50 in the adapter 5. The openings 50 in the modules 55 are preferably keyhole-shaped for receiving a Euro cylinder or a Swiss round profile cylinder, oval for receiving a cylinder with an oval cross-section, or circular for receiving a cylinder with a round cross-section. Depending on their inner contour 56, the modules 55 shown are thus suitable, for example, for a Euro cylinder 59, a UK oval cylinder 61, a Swiss round profile cylinder 62, or a Scandinavian oval cylinder 63. The oval cross-section of the modules 55 has the advantage that all modules can be inserted alternatively into the opening 50 of the adapter 5, so that the adapter 5 can be combined with common outer contours of the cylinders 16 in the modules 55.Furthermore, additional contours that deviate from the standard outer contours can be produced if required.

[0073] The modules 55 are to be interchangeable, i.e., replaceable at will, and inserted into the opening 50 of the adapter 5. The modules 55 therefore have locking elements, in particular locking hooks 54, and the adapter 5 has corresponding locking elements, in particular locking openings 53, in the area of ​​the opening 50 corresponding to the locking elements on the modules 55. How the Fig. 20 As can be seen from the diagram, the modules 55 preferably have locking elements in the form of locking hooks 54, which, according to the exemplary embodiment, are formed on both sides of the outer edge of the module 55. The locking openings 53 are, as shown in the diagram, Figs. 18 and 19The locking elements are preferably slot-shaped. In the assembled state, the locking hooks 54 engage in the locking openings 53. The modules 55 are thus clipped into the adapter 5. The locking elements 53, 54 therefore serve to provide a force-fit, yet detachable connection between a module 55 and an adapter 5.

[0074] In addition to the locking elements 53, 54, stop elements 57 and stop surfaces 52 can also be provided, as can be seen from the Figs. 18 to 20 can be removed. In the assembled state, the stop elements 57 of a module 55 are in operative connection with the stop surfaces 52 of an adapter 5. They form a positive-locking connection between module 55 and adapter 5. They thus contribute to the connection between module 55 and adapter 5 being secured against slippage.

[0075] The Figs. 17 and 18Figure 1 shows a view of the adapter 5, in which the surface 60 of the adapter 5 is visible, which, in the fully assembled state, rests against a door leaf or the like. This surface 60 of the adapter faces a user of the key-operated device 1 when the user inserts a module 55 into the adapter 5. To insert the module, the user can, for example, grasp the module 55 with two fingers, gently squeeze the locking hooks 54 together, insert the locking hooks 54 into the locking openings 53, and allow them to engage by releasing the pressure. In the assembled state, the module 55 is preferably arranged flush within the adapter 5 with the surface 60 of the adapter 5 facing the door leaf or the like.

[0076] The surface 60, which is aligned with a door leaf or the like, can have an adhesive device 51 at least in a partial area, leaving the opening 50 free for the locking cylinder 16, as shown in Fig. 17The adhesive device 51 also has an opening, specifically in the area where the adapter 5 has an opening 50 for the locking cylinder 16. The adhesive device 51 can preferably be a double-sided adhesive tape or an adhesive layer covered with a removable cover for activation. The adapter 5 can thus be attached to the door leaf or the like by means of the adhesive device 51.

[0077] Alternatively or additionally, the adapter 5 can be attached to a door leaf with screws. For this purpose, the adapter 5 preferably has holes 49 on both sides of the opening 50 for receiving screws.

[0078] Another embodiment provides that the module 55 has two bores 58 for receiving screws, which screws connect the module 55 to an end face 64 of the lock cylinder 16. The bores 58 are in Fig. 20 and Fig. 26as can be seen. The adapter 5 accordingly has two bores in the area of ​​the opening 50 for receiving modules 55.

[0079] Fig. 21 Figure 5 shows an adapter 5 with a module 55 for a Euro cylinder 59 and a Euro cylinder 59, part of the length of which is accommodated in the adapter 5. The adapter 5 is thus connected to the Euro cylinder 59 via the module 55, which has an inner contour 56 that corresponds to the outer contour of the Euro cylinder 59.

[0080] Similarly, it shows Fig. 22 an adapter 5 with a module 55 for a UK oval locking cylinder 61 and a UK oval locking cylinder 61 and Fig. 23 an adapter with a module 55 for a Swiss round profile and a Swiss round profile locking cylinder 62.

[0081] In Fig. 24An adapter 5 with a module 55 for a Scandinavian oval cylinder lock 63 is shown. In this figure, the housing 2 is attached to the adapter 5 by means of the snap-fit ​​elements 14 for housing attachment. The curvature of the U-shaped adapter 5 points in the opposite direction to that shown in the previous figures. This is due to the bores in the Scandinavian oval cylinder lock 63. When the cylinder lock 63 is installed in a door, these bores are located above the keyhole 17. However, since the adapter 5 is to be constructed identically for all module types 55, the bores 58 for the Scandinavian oval cylinder lock 63 in the adapter 5 must be located between the area for the power source 9 and the circular area 46.For mounting on the Scandinavian oval cylinder lock 63, the adapter 5, and thus the key operating device 1, must be rotated 180° compared to mounting on the other cylinder locks shown. Therefore, when mounting on a door or the like, the rotary knob 4 points downwards in the case of a Scandinavian oval cylinder lock 63 (see also...). Fig. 25 ), but upwards for the other lock cylinder types shown.

[0082] The invention is described in particular in connection with known locking cylinders 16 and the keys 17 used with them. Such a locking cylinder 16 need not be formed in one piece. Rather, locking elements formed in two pieces can also be provided, which on the one hand have a lever for actuating a lock, in particular for moving a latch and / or a bolt, and on the other hand have a connecting element between the two parts of the locking element. Such a locking element, which can again also be formed in one piece, is to be referred to as an actuating element within the meaning of the invention and must have an element that is rotatable within the lock, which can drive the mechanism of the lock via the lever. The invention can, for example, also be used after removing part of such a locking element by connecting the remaining part of the locking element to the connecting element.An adapter element may be provided for this purpose.
