Description

Field of the Invention

[0001] The present invention relates to an electromechanical locking device for a closing element or a switching element. Such a locking device is provided with a stator and a rotor as components and with a locking element. The rotor is supported in the stator. The locking element is supported in a first component of the components and is movable between a first position and a second position. In the first position, the locking element engages in a second component of the components. In the second position, the locking element is disengaged from the second component. The second component has a first abutment surface for the locking element, and the first abutment surface moves the locking element from the first position to the second position when the rotor rotates. Furthermore, the present invention relates to a locking device equipped with such a locking device. The locking device exists in many embodiments, for example, in the form of a lock core. Background Art

[0002] EP 1 914 368 B1 discloses a lock core having a locking element that is not only in the rotor but also in the stator in a first position, thereby blocking the rotation of the rotor relative to the stator. Conversely, in the second position of the locking element, the locking element is completely in the rotor, such that the rotor is rotatable relative to the stator. To move from the first position to the second position, a blocking element in the rotor is rotated from a blocking position to a release position. In the release position, the blocking element allows the locking element to move from the first position to the second position. The movement of the locking element is caused by an inclined abutment surface in the stator that presses the locking element into the second position when the rotor rotates. To keep the locking element spaced apart from the blocking element in the first position, a magnet is provided that holds the locking element in the first position. The disadvantage of this is that when the rotor moves, the locking element is always pressed against the blocking element by the abutment surface. Thus, the blocking element and the locking element may be damaged. Summary of the Invention

[0003] Accordingly, it is an object of the present invention to improve such a locking device such that the risk of damage to the locking device, in particular the blocking element and / or the locking element, is at least reduced during operation. Furthermore, in particular, a locking device equipped with such a locking device should be realized.

[0004] The object is achieved by an electromechanical locking device according to the invention for a closing element or a switching element. Advantageous refinements of the device are specified in the dependent device claims, the description, and the drawings. Furthermore, the object is also achieved by a locking device according to the invention. Advantageous refinements of the locking device are specified in the description and the drawings. The features and details described in connection with the locking device according to the invention are also applicable here in connection with the locking device according to the invention, and vice versa. Here, the features mentioned in the description and the claims are each individually or in combination can be essential for the present invention.

[0005] According to the present invention, a locking device is provided, which has a stator and a rotor as components and a locking element. The rotor is in particular rotatably supported in the stator. The locking element is supported in a first component of the components and can move between a first position and a second position. In the first position, the locking element engages in a second component of the components. In the second position, the locking element disengages from the second component. The second component has a first abutment surface for the locking element, and the first abutment surface moves the locking element from the first position to the second position when the rotor rotates. According to the present invention, the second component has a second abutment surface for the locking element, and the second abutment surface keeps the locking element in the first position, in which the locking element is in an engaged position with the second component.

[0006] Thereby, when the locking element abuts against the second abutment surface, it preferably does not have a force that can press the locking element against another element, in particular against a blocking element. This reduces the risk of damage to the locking element or the blocking element.

[0007] The first component can correspond to the rotor or the stator. Correspondingly, the second component corresponds to the other component of the components, that is, either the stator or the rotor. Thus, either the locking element can be supported in the rotor and engage in the stator in the first position, or the locking element is supported in the stator and engages in the rotor in the first position. The support of the locking element preferably involves a linear guide.

[0008] In the first position, the locking element prevents the rotor from rotating in the stator. Here, preventing rotation is understood as preventing the relevant range of rotation, for example so that a closing element can be unlocked. In the second position, the locking element enables the rotor to rotate in the stator.

[0009] Since the locking element remains in the first position when it abuts against the second abutment surface, further rotation of the rotor relative to the stator is prevented. Since the second abutment surface keeps the locking element in the first position, when an attempt is made to rotate the rotor, the rotation of the rotor stops when the locking element abuts against the second abutment surface. Here, no force is applied to the locking element towards the first position by the second abutment surface.

[0010] The locking device is preferably used to lock a spatial area. The spatial area is in particular fixed. For example, the spatial area can relate to a building space, such as an office, an apartment or a house, or to a storage space, such as a cabinet, a mailbox, a box, a case, a safe or a drawer. In particular, the locking device is used to be inserted into a closing element in the form of a door, such as a house door, an apartment door, a room door, a cabinet door, a mailbox cover or the front side of a drawer, or to be arranged at the closing element. Preferably, the stator of the locking device is at least indirectly torsionally connected to the closing element here.

[0011] The locking device can have or be connectable to a toggle member. The rotation of the rotor of the locking device serves to rotate the toggle member.

[0012] The toggle member is preferably configured as an eccentric member. The toggle member can be configured as a locking projection. It is possible that the rotation of the toggle member in a first direction serves to transfer the closing element from an unlocked state to a locked state. It is possible that the rotation of the toggle member in a second direction serves to transfer the closing element from a locked state to an unlocked state. For example, the locking device can be inserted at least indirectly into a mortise lock. In this case, the rotation of the toggle member can cause the movement of the bolt of the mortise lock. Thus, the rotation of the toggle member in the first direction can, for example, cause the bolt to move out, thereby causing the locked state of the closing element. The rotation of the toggle member in the second direction can, for example, cause the bolt to move in, thereby causing the unlocked state of the closing element.

[0013] Alternatively, the toggle member itself can act as a bolt. Thus, the rotation of the toggle member in the first direction can, for example, cause the toggle member to assume a locked position. The rotation of the toggle member in the second direction can, for example, cause the toggle member to assume an unlocked position.

[0014] In a preferred embodiment, the locking device is configured as a mounting device. The mounting device is configured to be inserted into the locking device housing of the locking device. Preferably, the mounting device is torsionally fixed in the locking device housing by means of fastening elements. Thus, in the installed state of the locking device, the stator of the locking device and the locking device housing form a common fixing unit. The locking device housing is particularly used for insertion into or placement at the closing element. The locking device can, for example, be configured as a lock cylinder, in particular a double lock cylinder or a half lock cylinder, a ball handle lock cylinder, a furniture lock cylinder or a padlock.

[0015] The locking device, in particular the rotor, can be connected or connectable to a ball handle or a key in order to transmit mechanical torque to the rotor.

[0016] If the locking device is configured as a mounting device, it is preferably provided that the locking device includes a connecting section for connection to the toggle member.

[0017] Alternatively, it can be provided that the locking device itself is configured as a lock cylinder, in particular a double lock cylinder or a half lock cylinder, a ball handle lock cylinder, a furniture lock cylinder or a padlock. Here, the stator simultaneously serves as a housing for insertion into or placement at the closing element.

[0018] Alternatively, the locking device can be designed for a switching element. Thus, the switching element can only be operated by an authorized user. Here, the toggle member can be used to operate a switch or a button. Thus, the locking device can be used in a switching element, in particular a key switch, or correspond to a key switch.

[0019] The electromechanical locking device especially includes an electromechanical actuator, especially an electric motor. The actuator is used to move the locking element into the second position.

[0020] The locking device may include an electronic control device, especially a processor and / or a controller, in order to control the actuator. The control device may include an electronic memory.

[0021] The locking device may include a transmission device. The transmission device may be configured as a sending and receiving unit, a biosensor, a keypad for PIN input, and / or a contact element for electrical contact of an electronic key in particular. The sending and receiving unit may be configured to communicate with a mobile unit, especially a mobile phone or a card, via wireless near-field communication, especially RFID or low-power Bluetooth.

[0022] The transmission device may be used to send and / or receive electronic data, and the electronic data enables determination of the user's authorization to unlock a spatial area or to operate a switch element. For example, the transmission device may receive an authorization code and / or an authorization time window verified by the control device. If the verification ends with a positive result, the actuator may be controlled to move the locking element into the second position.

[0023] Alternatively, the transmission device may receive an opening instruction, based on which the locking element moves into the second position in an electromechanical manner or is released to move into the second position in an electromechanical manner. The transmission device is especially additionally or alternatively used to transmit electrical energy to the locking device. The electrical energy may be designed to operate the actuator and / or for the control device.

[0024] Preferably, the locking device according to the present invention includes a blocking element. The locking device may include an electromechanical actuator assembly having a blocking element and an actuator.

[0025] Preferably, it is proposed that the blocking element allows the locking element to move from the first position to the second position in the release position and prevents the locking element from moving from the first position to the second position in the blocking position. The actuator is preferably used to move the blocking element from the blocking position to the release position. Therefore, the actuator may move the blocking element into the release position and / or cause the blocking element to move into the release position, for example, by tensioning a spring.

[0026] In particular, it may be proposed that when the blocking element is in the release position, the rotation of the rotor especially causes the locking element to move into the second position. Herein, in particular, the first abutting surface presses the locking element into the second position.

[0027] The second abutting surface is especially configured such that the locking element is spaced apart from the blocking element by abutting against the second abutting surface. Thereby, damage to the locking device can be prevented.

[0028] In particular, when the locking element is not acted upon and / or when the locking element is in contact with the second contact surface, the blocking element and the locking element can be spaced apart from one another in the first position of the locking element.

[0029] Preferably, the actuator assembly comprises an electromechanical actuator.

[0030] It can be proposed that the blocking element is arranged on the output shaft of the actuator configured as an electric motor. Preferably, the actuator realizes the rotation of the blocking element from the blocking position to the release position. For example, the actuator rotates the blocking element from the blocking position to the release position. This allows a very space-saving embodiment.

[0031] In particular, since the second contact surface spaces the locking element from the blocking element, it is feasible to support the blocking element on one side. Therefore, the output shaft can be supported in the actuator only on one side. The force acting on the blocking element by the locking element can be discharged on one side, in particular via the output shaft.

[0032] In order to space the blocking element and the locking element apart when they are in contact with the second contact surface, the locking element may include a protruding top surface. The second contact surface may be configured accordingly. The top surface and the second contact surface are configured such that when the locking element is in contact with the second contact surface, the second contact surface is between the top surface and the blocking element.

[0033] Alternatively or additionally, the movement of the locking element between the first position and the second position defines a movement direction, wherein the top surface and the second contact surface are configured obliquely relative to the movement direction of the locking element. Thus, the force acting on the locking element can be directed into the stator.

[0034] Preferably, the blocking element comprises a recess into which the locking element is arranged in the second position. In contrast, in the first position, the locking element is outside the recess. In the release position, the blocking element is arranged so that the recess and the locking element are opposite each other, so that the locking element can be moved into the recess.

[0035] The blocking element can be designed, for example, in the form of a disk.

[0036] Preferably, the second component comprises a component element, which has a first contact surface and is movably supported in the remaining second component. In particular, it can be achieved that the locking element is abutted against the second contact surface by the movement of the component element. The component element preferably has no fixed connection or support with the first component.

[0037] It can be proposed that the component element and the locking element move relative to each other when the rotor rotates. In the release position of the blocking element, the locking element moves from the first position to the second position. In the blocking position of the blocking element, the component element moves so that the locking element abuts against the second abutment surface.

[0038] It can be stated that the component element can move between a first position and a second position. In the first position, a first abutment surface abuts against the locking element such that, when the rotor rotates, the locking element moves from the first position into the second position. In the second position of the component element, the locking element abuts against a second abutment surface such that the locking element remains in the first position. That is to say, in the above rotation, the component element must first move into the desired second orientation so that the second abutment surface can become effective. This enables a targeted initiation of the movement of the locking element from the first position into the second position or a targeted retention in the first position.

[0039] At least one locking element recess is defined between at least one first component element and at least one second component element, wherein the locking element is arranged in the locking element recess in the first position. The rotation of the rotor is particularly prevented by the locking element engaging into the locking element recess in the first position of the locking element. In the second position, the locking element is outside the locking element recess.

[0040] In the first orientation of the component element, the first abutment surface is closer to the locking element than the second abutment surface. The first abutment surface bounds the locking element recess in the first orientation of the component element. In the second position of the component element, the second abutment surface projects more into the locking element recess than the first abutment surface.

[0041] If a plurality of locking element recesses are provided, for example so that after a rotation angle range of less than 360° of the rotor, the locking element can reach the first position again from the rest position, the locking element recesses are preferably each surrounded by a first abutment surface and a second abutment surface as described for the locking element recess.

[0042] The movement of the component element between the first orientation and the second orientation preferably includes a component perpendicular to the movement of the locking element between the first position and the second position. In particular, the movement of the component element between the first orientation and the second orientation takes place perpendicular to the movement of the locking element from the first position into the second position.

[0043] The second component can include at least one spring element which presses the component element into the first orientation, wherein the spring element is supported in the second component. Thereby, an automatic reset of the component element into the first orientation is achieved, which enables simpler movement control.

[0044] Preferably, the locking element is pre-tensioned into the first position by a spring.

[0045] It is preferably provided that the force acting on the locking element via the spring is less than the force acting on the component element via the spring element. It is possible that the spring constant of the spring is configured to be less than the spring constant of the spring element. Thereby, when the locking element can be displaced into the second position, it is possible for the spring element to retain the component element in the first orientation.

[0046] Preferably, the locking element is arranged between at least one first component element and at least one second component element. Thus, when the rotor rotates both clockwise and counterclockwise, as long as the blocking element allows movement into the second position, the locking element moves into the second position via the first abutment surface.

[0047] It can be provided that in the first position, at least one first component element and / or at least one second component element abuts against the locking element.

[0048] Preferably, the locking element is arranged between the second abutment surfaces. Thus, when the movement of the locking element into the second position is prevented especially by the blocking element, when the rotor rotates both clockwise and counterclockwise, the locking element moves towards the second abutment surface.

[0049] Preferably, the first component is configured as a rotor and the second component is configured as a stator. Thus, the locking element is movably supported in the rotor and engages in a locking element recess of the stator in the first position.

[0050] Preferably, the locking element is in the rotor. The stator includes component elements. The component elements are configured as stator elements in this case. In this case, the locking element rotates with the rotor. In contrast, the component elements do not rotate with the rotor. The component elements remain in the stator when the rotor rotates. Through the support of the component elements in the stator, the component elements are preferably movable in a preset region in the stator. In contrast, the region itself is preferably fixed in position.

[0051] Especially when the second component is configured as a stator, the stator preferably includes a stator body and / or at least one stator insertion element. Thereby, the installation can be simplified.

[0052] The stator body can include a stator void that can be accessed from the outer circumference, and the stator insertion element can be inserted into the stator void.

[0053] Preferably, the stator insertion element includes a second abutment surface.

[0054] It can be provided that the stator insertion element includes guide surfaces for stator elements, preferably for a first stator element and a second stator element.

[0055] In particular, the stator may include a housing. Herein, the remaining stator parts, in particular the stator body, the stator insertion elements and / or the stator elements, are inserted into the housing.

[0056] It can be proposed that the rotor includes at least one axial first section, in particular a first rotor element, and an axial second section, in particular a second rotor element. The second section preferably has a smaller diameter than the first section.

[0057] It can be proposed that the locking element is arranged in the axial second section. Thereby, sufficient structural space exists in the stator to provide a first abutment surface and a second abutment surface. Preferably, sufficient structural space is provided in the stator to provide one stator element or a plurality of stator elements.

[0058] In all the embodiments mentioned, the first abutment surface and the second abutment surface can be arranged axially in sequence with respect to the rotor axis. In particular, the first abutment surface axially surrounds the second abutment surface. Thus, the second abutment surface is provided in each rotational direction and is surrounded by a plurality of first abutment surfaces. Thereby, uniform movement of the locking element is achieved.

[0059] Preferably, the locking element includes a first abutment section for abutting against the first abutment surface and a second abutment section for abutting against the second abutment surface. Herein, the first abutment section and the second abutment section are preferably rigidly connected to each other. The first abutment section and the second abutment section are preferably arranged in sequence in the axial direction. This enables a simple construction of the locking element.

[0060] The first abutment section can be configured corresponding to the first abutment surface such that the first abutment section and the first abutment surface can abut against each other in a surface-to-surface manner.

[0061] The second abutment section can be configured corresponding to the second abutment surface such that the second abutment section and the second abutment surface can abut against each other in a surface-to-surface manner.

[0062] It can be proposed that the locking element extends such that the locking element can only abut against the second abutment surface by rotation of the rotor. For example, it is not necessary to axially offset the locking element relative to the rotor axis in order to bring the locking element into abutment against the second abutment surface.

[0063] It can be proposed that the locking element preferably extends in the axial direction with respect to the rotor axis such that the locking element can abut against not only the first abutment surface but also the second abutment surface.

[0064] The locking element notch includes a first side and a second side. The locking element abuts against the first side when the rotor rotates to the right, and the locking element abuts against the second side when the rotor rotates to the left, wherein the first abutment surface is provided on the first side and the second abutment surface is provided on the second side.

[0065] Preferably, the locking element includes a third abutment section for abutting against the blocking element, in particular for engaging into the blocking element. The third abutment section is preferably rigidly connected to the first abutment section and / or the second abutment section.

[0066] In particular, the locking device may include a locking element for locking the rotor in at least one position relative to the stator. The locking element holds the rotor in a position in which the locking element is not pressed from the first abutment surface towards the blocking element. Thereby, the locking element is reliably held in the position and cannot inadvertently leave the position.

[0067] In all the mentioned variants, the locking element can be integrally formed.

[0068] Furthermore, according to the present invention, a locking device is proposed, which is provided with the locking device according to the present invention. Here, the locking device is configured as a mounting device. Description of the Drawings

[0069] The present invention will be described in detail below with reference to embodiments. Technical features with the same functions are provided with the same reference numerals in the drawings. The drawings show:

[0076] Figure 9 showing the locking device according to the present invention in a partially disassembled state according to a second embodiment. Detailed Description of the Embodiments

[0077] Figure 1 The locking device 100 is shown in the form of a lock cylinder as used in a mortise lock in a known manner, so that a building door as a closing element can be unlocked or locked by means of a latch. For this purpose, the locking device 100 has a housing 101 with notches, and a toggling element 103 configured as a locking projection is rotatably arranged in the notches. The toggling element 103 is used to move the latch in the locking direction or the unlocking direction.

[0078] In the right half of the housing 101 here, a locking device 1 configured as a mounting device according to an embodiment of the present invention is inserted. The mounting device 1 includes a stator 10, and a rotor 30 of the mounting device 1 is inserted into the stator in a rotatable manner about a rotor axis 35, and the rotor axis is exemplarily coincident with the rotation axis of the toggling element 103. The rotor 30 includes a key channel 36 for inserting the rod of a key 200 on its front side 37 facing away from the toggling element 103. The key 200 carries an electronic locking code in the form of electronic data. The user's permission to unlock the door can be determined according to the locking code. The key 200 is preferably configured in a manner without mechanical coding. Therefore, only according to the electronic locking code can it be determined whether the user is authorized. Here, the key and the locking device can be mechanically identical to each other.

[0079] Figure 2 The locking device 100 is shown, and the locking device is partially disassembled from each other. The housing 101 has openings 104 in the lower region in two halves for the notches of the toggling element 103, and the right opening is provided with a reference numeral. The opening 104 here extends perpendicular to the rotation axis of the toggling element 103. The toggling element 103 exemplarily has an inner profile with a non-circular cross-section, for example in the form of an internal tooth portion, and an insert 105 is preferably engaged with the inner profile in a form-fitting manner. For this purpose, the insert 105 has an outer profile which is preferably designed to be complementary to the inner profile of the toggling element 103 and is in the form of an external tooth portion here, so that the two components 103, 105 are arranged torsionally resistant relative to each other.

[0080] A connecting section 38 of the mounting device 1 extends into the insert 105. In the connecting section 38, a coupling member 41 is movably arranged in a guide 42. The coupling member 41 is configured in multiple parts. The coupling member 41 can establish or release an effective connection between the rotor 30 and the toggling element 103 via the insert 105 especially according to the position of the coupling member 41. For this purpose, the coupling member 41 of the locking device 100 can be engaged with an inner profile (not shown) of the insert 105 in a form-fitting manner. The guide 42 preferably forms a linear guide for the coupling member 41, so that the coupling member 41 is arranged in a manner that can be guided along the rotor axis 35 of the rotor 30.

[0081] The mounting device 1 has a housing 14, by means of which the mounting device 1 is pushed into the associated insertion opening 106 of the housing 101. The fastening element 102 in the form of a screw passes through the notch 104 on the right here from the underside of the housing 101 and is screwed into the opening 21 on the left here of the housing 14 of the stator 10 and of the stator body 11 of the stator 10 to be described in more detail later. Thereby, the screw 102 fixes the stator 10 in the housing 101. In addition, a key channel 36 for introducing the key 200 is marked here, which is formed in the first rotor element 32 of the rotor 30.

[0082] Figure 3 The mounting device 1 without the housing 14 is shown. The stator body 11 is also formed in a sleeve shape, but has a functional structure inside. The stator body 11 has a stator void 19, into which the stator insertion element 13 is inserted. On the side of the stator insertion element 13 facing the inside of the stator body 11, the component element 12 to be described in more detail later is arranged or provided. The component element 12 is movably supported at the stator insertion element 13 and the stator body 11. The component element 12 remains in the remaining stator 10 when the rotor 30 rotates. Therefore, the component element 12 is configured as the stator element 12.

[0083] The rotor 30 includes a first rotor element 32 and a second rotor element 33.

[0084] The rotor 30 can rotate freely in the stator body 11 of the stator 10, but is supported in a position-fixed manner in the direction of its rotor axis 35, which extends parallel to the insertion direction of the key 200 into the key channel 36. The coupling member 41 is provided on the second rotor element 33 of the rotor 30 of the mounting device 1 in a torsion-resistant manner. The two rotor elements 32, 33 are reversibly releasably fastened to each other, for example by means of screws 24, and are rotatably arranged in the stator body 11.

[0085] The second rotor element 33 has a guide portion 42, into which the coupling member 41 engages so as to be arranged in a torsion-resistant manner relative to the second rotor element 33. The second rotor element 33 is inserted into the stator body 11 from the bottom side 23 of the stator 10, more precisely preferably inserted into the stator body without the first rotor element 32 during installation.

[0086] Figure 4 The mounting device 1 without the housing 14, the stator body 11 and the coupling member 41 is shown in a partially disassembled state.

[0087] There is an extension element 40, and the key 200 interacts mechanically with the extension element. If the key 200 is pushed into the key channel 36, upon contact, the key causes the extension element 40 to move axially or parallel to the rotor axis 35. Thereby, the extension element 40 can extend the effective range of the key 200. The key and thus the key channel 36 can hereby have a small depth. For example, the key channel 36 can be delimited by the first rotor element 36.

[0088] Here, the extension part 40 moves the coupling part 41 away from the rotor 30 towards the actuating element 103, such that the coupling part 41 can be rotationally engaged with the actuating element 103. In the connecting section 38, there is a passage 39 for bringing the extension element 40 into contact with the coupling part 41. Here, either the extension element 40 or the coupling part 41 can project through the passage 39.

[0089] There is a transmission element 44, for example in the form of a coil, for establishing a data and / or energy transmission connection with the key 200. Thereby, it is possible to read from the key 200 or receive electronic data from the key 200, such as authentication information or opening instructions. The electronic control device 53 is coupled to the coil for reading and, if necessary, evaluating the data. If the verification by the control device 53 yields that the user of the key 200 is authorized to open the associated door and / or the control device 53 has an opening instruction, the electromechanical actuator assembly 50 is activated. The actuator assembly 50 includes an electromechanical actuator 52 in the form of an electric motor here, at the output shaft of which a blocking element 51 is torsionally fixed. The blocking element 51 includes a cutout 54, which will be elaborated in detail later.

[0090] The locking element 31 is preferably supported in the second rotor element 33 perpendicular to the rotor axis 35 so as to be movable towards and away from the blocking element 51. In the first position shown here, the locking element 31 is in the locking element recess 15 (see Figure 5 ), which is formed by the stator insert element 13 and the stator element 12. Thereby, the rotation of the second rotor element 33 and thus of the coupling part 41 is prevented. The rotation of the inserted key 200 for unlocking the associated lock is blocked or prevented. In a second, not shown position of the locking element 31, the locking element 31 disengages from the locking element recess 15 of the stator 10. Thereby, it is possible to rotate the rotor 30 in the stator 10 and thus to rotate the actuating element 103.

[0091] The locking element 31 is pressed into the first position by at least one spring 34 (see Figure 5 ), preferably by a plurality of springs 34. In the Figure 5 embodiment, there are a plurality of springs 34.

[0092] Figures 5 to 7 ShownFigure 4 Selected components of the mounting device 1 therein. Here, Figure 5 The arrangement of the locking element 31 with respect to the blocking element 51 and the stator insertion element 13 together with the stator element 12 is shown.

[0093] The blocking element 51 can rotate between a release position and a blocking position. In the release position, the void 54 is opposite the locking element 31 so that the locking element 31 can be moved into the void 54. In the blocking position, the void 54 is not opposite the locking element 31, so that the locking element 31 is prevented from moving into the void 54. In Figure 4 and Figure 5 The blocking position of the blocking element 51 is shown.

[0094] When the blocking element 51 is in the release position and the void 54 is opposite the abutment section 63 of the locking element 31, i.e., pointing upward in Figure 5 , the locking element 31 is designed with an abutment section 63 facing the blocking element 51 so that it can be moved into the void 54. Thus, it is possible for the locking element 31 to reach the second position.

[0095] The first abutment surface 16 of the stator element 12 facing the locking element 31 is designed such that when the rotor 30 continues to rotate, the locking element 31 is pressed towards the blocking element 51, i.e., pressed into the second position, in which the rotor 30 can rotate freely relative to the stator 10. The first abutment surface 16 is configured as an inclined surface that presses the locking element 31 into the second position. Here, the first abutment surface can be configured straight, convex, or concave.

[0096] The stator element 12 is supported at the stator insertion element 13 and the stator body 11 in a manner movable between a first orientation and a second orientation. The stator element 12 is pressed into the first orientation by means of a spring element 18. The spring element 18 is supported in the stator 10. The movement of the stator element 12 from the first orientation to the second orientation according to the movement direction 71 is perpendicular to the movement direction 70 of the locking element 31 at the start of the movement.

[0097] During the process of unlocking the rotor 30 relative to the stator 10, the locking element 31 is first in the locking element notch 15. Here, the locking element 31 is guided in the rotor 30. Additionally, the locking element 31 abuts against the first abutment surface 16 of the stator element 12. Thereby, the locking element 31 is centered. The said position of the locking element 31 is called the rest position. In the rest position, the locking element 31 is preferably arranged at a distance from the blocking element 51.

[0098] The user now wants to unlock the door and insert the key 200 into the key channel 36. Thereby, the electronic communication between the key 200 and the control device 53 is started, in which it is determined electronically whether the user is authorized.

[0099] If the user is authorized to unlock the door, the control device 53 actuates the actuator 52. The actuator 52, which is designed as an electric motor, rotates the blocking element 51 into the release position, in which the recess 54 is opposite the locking element 31. If the rotor 30 is now rotated by means of the key 200, the locking element 31 slides along one of the first abutment surfaces 16 into the second position, in which the locking element 31 engages in the recess 54. Here, the spring 34 is tensioned. The locking element 31 moves in the direction of movement 70.

[0100] For this purpose, the first abutment surface 16 forms an acute angle α with the direction of movement 70 of the locking element 31 (see Figure 8 ).

[0101] The stator element 12 remains in the first orientation here. This is achieved in that the spring element 18 exerts a higher force on the stator element 12 than the force exerted by the spring 34 on the locking element 31, along which the locking element 31 slides.

[0102] The rotor 30 can now rotate freely. The locking element 31 slides along the first abutment surface 16 into which the locking element 31 rotates. The locking element 31 is surrounded by the first abutment surface 16 in both rotational directions, such that when abutting against at least one of the first abutment surfaces 16, the rotation in both directions allows the locking element 31 to move into the second position. In order to have the first abutment surface 16 in both rotational directions, the locking element notch 15 is surrounded on both sides by at least one first stator element 12, 12a and a second stator element 12, 12b (see Figure 7 ).

[0103] According to the invention, it is proposed that the stator 10 has a second abutment surface 17, which keeps the locking element 31 in the first position. The second abutment surface 17 is used functionally when the user is not authorized to unlock the door. The second abutment surface is formed in the stator insertion element 13. If the locking element 31 is in the rest position, the second abutment surface 17 is spaced further apart from the locking element 31 than the first abutment surface 16.

[0104] Preferably, the second abutment surface 17 is also inclined, however, opposite to the first abutment surface 16 with respect to the direction of movement 70 of the locking element 31. Thus, the second abutment surface 17 forms an obtuse angle β with respect to the direction of movement 70 of the locking element 31 (see Figure 8 ).

[0105] Viewed along the axis of rotation of the blocking element 51 and / or the rotor axis 35, the locking element 31 has, at its end facing the stator insertion element 13, a cross-section which has a preferably symmetrical trapezoidal shape tapering towards the blocking element 51. The lateral sides of the trapezoid form a top surface 60 facing outwards with respect to the locking element 31. The top surface 60 and the corresponding abutment surface 17 are formed inclined with respect to the direction of movement of the locking element 31.

[0106] If the user is not authorized to unlock the door, the following process occurs. The locking element 31 is initially in the rest position. A key 200 without locking authorization is inserted into the key channel 36. The electronic data exchange shows that there is no authorization for unlocking the door. Therefore, the actuator 52 is not actuated and the blocking element 51 remains in the blocking position, in which the cut-out 54 is not opposite the locking element 31, as shown in Figure 4 and Figure 5 . More precisely, the outer circumference of the blocking element 51 is opposite the locking element 31.

[0107] If the rotor 30 is rotated, the locking element 31 attempts to slide along the first abutment surface 16. However, this is unsuccessful because the locking element 31 abuts on the outer circumference of the blocking element 31. Therefore, the locking element 31 cannot be pressed into the second position against the force of the spring 34.

[0108] Instead, the stator element 12 in the direction of rotation of the locking element 31 is pushed back by the locking element 31 against the force of the spring 18 until the locking element 31 abuts at the second abutment surface 17. The stator element 12 is now in the second orientation.

[0109] Here, the top surface 60 of the locking element 31 abuts against the corresponding second abutment surface 17 opposite the lateral side of the trapezoid.

[0110] In this state, one stator element 12 or a plurality of stator elements 12 have moved back in the direction of rotation against the force of the spring element 18. The spring element 18 presses the stator element 12 against the locking element 31 when the rotor 30 is further rotated.

[0111] The abutment surface 17 is configured such that the abutment surface 17 holds the locking element 31 in the first position. Therefore, the rotor 30 remains blocked by the locking element 31 such that unlocking of the door does not occur.

[0112] Each second abutment surface 17 corresponds to the respective facing top surface 60 of the locking element 31. The surface 60 and the respectively corresponding abutment surface 17 are configured such that when the locking element 31 abuts at the abutment surface 17, the abutment surface 17 is between the surface 60 and the blocking element 51.

[0113] If an attempt is made to further rotate the rotor 30, the locking element 31 slides away from the blocking element 51 in the opposite direction to the direction of movement 70. This is achieved by means of the inclined surface of the second abutment surface 17. The locking element 31 can slide along the second abutment surface 17 with its top surface 60. Thus, the locking element 31 and the blocking element 51 can be spaced apart from each other when they are in contact with the second abutment surface 17. Additionally or alternatively, the force acting on the locking element 31 during a further attempt to rotate the rotor 30 is conducted into the second abutment surface 17. This is facilitated by the fact that the top surface 60 corresponds to the second abutment surface such that the locking element 31 abuts against the second abutment surface in a surface-to-surface manner.

[0114] Thereby, the risk of damage to the blocking element 51 is reduced.

[0115] Thereby, it is particularly possible to support the blocking element 51 unilaterally.

[0116] In Figure 5 the locking element cutout is provided with the reference numeral 15. Figure 6 shows the arrangement of Figure 5 viewed from the end side of the locking element 31, only without the blocking element 51. Here, the stator element 12 is in the second orientation. In Figure 7 the same elements as in Figure 6 are shown in another perspective view. Additionally, in Figure 7 the spring element 18 is shown, and on the left side, the spring receiving portion 65 of the stator 10 for receiving the spring element 18 is shown, while on the right side, the spring receiving portion 65 is not shown.

[0117] The locking element 31 is surrounded by the second abutment surface 17 in both rotational directions such that when it abuts against one of the second abutment surfaces 17, rotation in both rotational directions retains the locking element 31 in the first position.

[0118] In the first orientation of the stator element 12, the first abutment surface 16 is closer to the locking element 31 than the second abutment surface 17. In the second orientation of the stator element, the second abutment surface 17 projects more into the locking element recess 15 than the first abutment surface 16.

[0119] The first and second abutment surfaces 16, 17 are arranged axially one behind the other in the direction of the rotor axis 35. In the illustrated embodiment, for example, four first abutment surfaces 16 are provided, with two first abutment surfaces 16 provided in each rotational direction of the rotor 30. For this purpose, two first stator elements 12a are provided on one side of the locking element recess 15, and two second stator elements 12b are provided on the other side of the locking element recess 15.

[0120] In Figure 7As shown, the two first abutment surfaces 16 respectively surround the second abutment surface 17 in the axial direction. Thereby, the locking element 31 is pressed into the second position particularly evenly by the first abutment surfaces 16.

[0121] The locking element 31 extends in the axial direction with respect to the rotor axis 35 such that the locking element 31 can abut not only against the first abutment surface 16 but also against the second abutment surface 17.

[0122] The locking element 31 is integrally formed. Thereby, the first abutment section 64 of the locking element 31 for abutting against the first abutment surface 16 is rigidly connected to the top surface 60 for abutting against the second abutment surface 17. Here, the top surface 60 serves as the second abutment section. The first and second abutment sections 60, 64 are rigidly connected to the third abutment section 63 of the locking element, which is used for abutting in the clearance 54. In a variant (not shown) of the embodiment, the first abutment section 64 is matched to the first abutment surface 16, that is, the locking element 31 can be designed, for example, as a trapezoid widening towards the blocking element 51 in the first abutment section 64. Thereby, the locking element 31 can slide in a surface-like manner along the first abutment surface 16.

[0123] For example, four stator elements 12 are bounded outwardly on one side by the guide surface 62 of the stator insertion element 13 when moving between the first and second orientations. The stator elements 12 are bounded inwardly by a non-shown guide surface of the stator body 11.

[0124] By the stator including the stator body 11 and the stator insertion body 13, the installation of the mounting element 1 becomes easier. The housing 14 is used to fasten the stator insertion body 13 in the stator body 11.

[0125] The first rotor element 32 has a larger diameter than the second rotor element 33. The stator elements 12 and the stator insertion body 13 are arranged in the section of the stator 10 surrounding the second rotor element 33. Due to the small diameter of the second rotor element 33, it is possible to provide the first and second abutment sections 16, 17 in the stator 10.

[0126] The circumferentially formed protrusion 43 of the second rotor element 33, here as a flange, serves as a stop for the second rotor element 33 at the stator 10. The protrusion 43 is preferably formed integrally with the second rotor element 33. Thereby, the second rotor element 33 is axially fixed towards the front side 37.

[0127] During installation, the first rotor element 32 can be inserted into the stator 10 from the front side 37. The first rotor element 32 is axially fixed towards the actuating element 103 by means of the end face 66 facing the second rotor element 33. Here, the end face 66 abuts against the internal structure of the stator 10, in particular the stator body 11. The second rotor element 33 can be inserted from the bottom side 23 until the projection 43 abuts against the bottom side 23. By connecting the two rotor elements 32, 33, the resulting rotor 30 is axially fixed forwards and backwards.

[0128] A locking element 61 is provided, which holds the rotor 30 in position with respect to the stator 10 (see Figure 4 ). Here, the rotation of the rotor 30 is impeded in the stator by the locking element 61, such that the locking element 31 can assume a stationary position. The locking element 61 is formed, for example, by a spring-loaded locking projection. That is, the rotor 30 can pass over the locking projection 61 during rotation, such that the function of the rotor 30 is maintained.

[0129] The annular projection 22 is formed by means of a particularly half-shell-shaped part, the mutually facing inner surfaces 26 of which cooperate in a snap-locking manner with the key 200. The part is inserted into the circumferentially formed groove 45 of the first rotor element 32. The outwardly projecting projection 25 of the annular projection 22 fixes the parts of the projection 22 in the stator body 11 in their relative positions with respect to one another and with respect to the stator body 11. The annular projection 22 and the inserted key 200 preferably serve as a key removal locking mechanism in a snap-fastening manner.

[0130] The extension element 40 is angled in the example shown. Here, the first part of the extension element 40 intended for interaction with the key 200 extends radially further outwards than the second part of the extension element 40 intended for interaction with the coupling part 41. Thereby, the second part can be arranged more centrally in order to be able to better push the coupling part 41.

[0131] The extension element 40 is configured to push the coupling part 41, but does not engage with the coupling part 41 in a form-fitting manner. This enables the extension element 40 to be configured finely.

[0132] The extension element 40 serves to mechanically and / or magnetically retract the blocking element 51 from the release position back into the blocking position. Here, the extension element 40 can move back to the starting position when the key is removed. When the extension element moves to the starting position, it can cause or allow the blocking element 51 to move to the blocking position. For example, a spring (not shown) can be tensioned during the movement of the blocking element 51 to the release position. When the key is inserted, the extension element 40 holds the blocking element 51 in the release position, and when the extension element 40 together with the key 200 moves forward towards the front side 37 when the key is removed, it allows the blocking element 51 to move back to the blocking position.

[0133] Figure 9 Another embodiment of the locking device according to the invention is shown. Here, Figure 9 is shown corresponding to Figure 4 in the view, i.e., the housing 14 and the stator body 11 are not shown. Only the differences from the Figures 1 to 8 first embodiment will be discussed below.

[0134] Instead of the screw 24, the first rotor element 32 includes a fastening mechanism 67 and the second rotor element 33 includes a corresponding fastening mechanism 68 which engage form-fittingly with each other such that the first rotor element 32 and the second rotor element 33 are torsionally fastened to each other in the rotational direction. Here, the first and second fastening mechanisms 67, 68 are configured as a protrusion and a corresponding notch.

[0135] Instead of a coil as the transmission device 44, a contact element is provided as the transmission device 44 which transmits data and / or electrical energy to the locking device 1 via electrical contact with the key 200. The contact element 44 is elastically fastened to the housing 46.

[0136] The housing 46 simultaneously serves to axially fix the rotor elements 32, 33 to each other. For this purpose, the housing 46 includes a first locking element 47 which locks into the first rotor element 32. For this purpose, the first rotor element 32 includes an edge 78. The housing 46 includes a second locking element 48 which locks into the second rotor element 33. For this purpose, the second rotor element 33 includes a groove (not shown).

[0137] The first rotor element 32 is axially fixed in both directions along the axis of rotation by a snap ring 72. The snap ring 72 is arranged in a groove 73 of the first rotor element 33.

[0138] A locking element 61 configured as a ball is arranged in the stator 10 and engages in a notch 69 of the first rotor element 32.

[0139] The mounting device 1 can also be used in other locking devices, for example in half-cylinders, ball handle cylinders, furniture cylinders or padlocks.

[0140] It is conceivable that the coupling member 41 is missing. More precisely, a locking device according to the invention can be provided, wherein the actuating member 103 is rigidly fastened to the rotor 30. In addition, the actuating member 103 itself can be used as a bolt, for example, in a furniture lock. The actuating member 103 and the insert member 105 can be integrally formed with each other.

[0141] The stator insertion element 13 and the stator body 11 can be integrally formed. It is also conceivable that the housing 14 is missing and the stator body is directly fastened in the locking device housing 101.

[0142] In another alternative of the invention, the locking device 1 is not configured as a mounting device 1. More precisely, the stator 10 is configured as the locking device housing 101. Thus, the rotor 30 can be configured to be directly pushed into the lock cylinder housing 101. The locking device housing 101 then assumes the function of the stator 10.

[0143] The locking element 31 can also be supported in the stator 10 such that the locking element presses against the rotor 30. The first and second abutment surfaces 16, 17 are formed in the rotor in this case.

[0144] In the embodiment of the drawings, the abutment surfaces 16, 17 are configured such that the first abutment surface 16 surrounds the second abutment surface 17 or the second abutment surface 17 surrounds the first abutment surface 16. However, the abutment surfaces can also be arranged in other ways relative to each other.

[0145] The transmission device 44 can be configured as a contact element for electrically contacting the key in the first embodiment, or can be formed by a contactless coil in the second embodiment.

[0146] In the first embodiment, it can be fastened by a locking mechanism as in the second embodiment.

[0147] It can be that the actuator moves the blocking element back into the blocking position. The blocking element can in particular be provided in a ball handle lock cylinder.

[0148] Alternatively, the blocking element 51 can be configured in a tappet shape. In this case, a bistable magnet is preferably suitable as the actuator. The tappet can be spring-loaded in one direction, preferably in the direction away from the magnet.

[0149] The rotor 30 does not have to have a plurality of rotor elements 32, 33. However, the rotor 30 can include sections with different diameters.

[0150] The embodiments of the present invention are not limited to the above preferred embodiments. Rather, a large number of variant forms are conceivable, which utilize the described solution even in embodiments of different types in principle. All features and / or advantages resulting from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential for the present invention not only in themselves but also in the most diverse combinations.
