LOCKING SYSTEM FOR ONE DOOR AND DOOR ARRANGEMENT WITH ONE LOCKING SYSTEM

Description

[0001] The invention relates to a locking cylinder for a door, a locking system for a door and a door arrangement with such a locking system.

[0002] Various locking cylinders are known from the prior art that are used in conjunction with a door lock and are used to operate it. For this purpose, the respective locking cylinder is inserted into a cylinder hole formed on a lock case of the door lock. The locking cylinder comprises a cylinder housing that extends in a longitudinal direction and has a core into which a key can be inserted and which, via a coupling, can establish a rotationally fixed connection to a locking bit that can be pivoted in a recess in the cylinder housing and represents a lock driver that transmits an adjusting force exerted by the key to a locking and locking mechanism of the door lock. Actuation of the locking bit thus activates the locking and locking means of the door lock, such as a latch, a bolt, a secondary bolt, and / or the like.The locking cylinder is usually designed as a so-called double cylinder, i.e. it has a core on both sides of the cylinder housing into which a key can be inserted to operate the cam and thus the locking and locking mechanism of the door lock. So-called half cylinders are also known, which have a core on only one side for inserting a key. In addition, so-called knob cylinders are known, in which a knob is permanently attached to the core, which acts as a handle for the locking cylinder. The knob allows keyless operation of the door lock. It is also known to provide a double cylinder with a knob on one side and a core on the other side for inserting a key.

[0003] The locking cam or lock driver is typically designed like a locking lug, which, when rotated at a specific position, is received in the recess of the cylinder housing, allowing the locking cylinder to be inserted into the cylinder hole of the lock case without resistance. The locking cylinder is secured to the lock case by a screw that is screwed in from a faceplate of the mortise lock at right angles to the axis of the cylinder housing.

[0004] The locking cylinder of the type described above is operated exclusively by means of a key or a knob. There is no additional or alternative drive option using a motor or the like.

[0005] According to the abstract, DE 19757192 A1 describes a lock equipped with a locking cylinder and a gear motor. The locking cylinder, which penetrates a mortise lock, forms halves extending on both sides of the locking element. The free end sections of these halves can be supported by the respective fitting plate. One of the halves has a drive wheel that is rotationally connected to the locking element. In order to achieve a design that is simple to manufacture and advantageous in terms of drive, the invention proposes that the drive wheel be arranged between the locking element and the end section, and that the gear motor be arranged in the vertical plane of the mortise lock.

[0006] WO 2019 / 220084 A1, according to the translation of the abstract available at Espacenet, describes a cylinder lock comprising: a cylinder lock housing for receipt in a bore in a bracket, the housing having a front end and a rear end, and the housing having at its front end a first bore for receiving a first rotatable lock drive member for rotation within the first bore; a cam connectable to the first rotatable lock drive member for rotation therewith, the cam being suitable for actuating a locking mechanism upon rotation of the cam; the cam having a first position and a second position, the cam moving in a first direction relative to the bracket when moving from its first position to its second position;wherein the cylinder lock further comprises biasing means for biasing the cam towards its second position; and retaining means for retaining the cam in its first position; wherein the cylinder lock is adapted such that, when the cylinder lock is tampered with by movement or breakage of the retaining means, the cam is caused to move from its first position to its second position, the first position of the cam being an aligned position in which the cam is aligned with the locking mechanism so that it can actuate the locking mechanism, and the second position being a misaligned position in which the cam is not aligned with the locking mechanism and cannot actuate the locking mechanism.

[0007] EP 0276037 A2, according to the translation of the abstract available at Espacenet, describes a lock set, particularly for use in access control systems, comprising a cylinder unit of a standard design, operable from the outside by means of a key and from the inside by means of a rotary knob. However, instead of the normal knob, the cylinder unit has a coupling into which fits a shaft of a motor unit mounted on the inside of the door. In normal operation, the motor is operated to unlock and then relock the door by rotating the shaft in opposite directions to rotate the cylinder cam accordingly. The extent of this movement is controlled by a limit / reverse switch operated by a cam on the shaft. Operation from the outside can also be achieved by key operation of the cylinder unit, and a knob is provided at the accessible end of the shaft for emergency operation from the inside.Due to the permanent connection between the cylinder cam and the shaft, the limit / reverse switch is always in the correct position for subsequent operation of the motor in the corresponding sense, regardless of whether the last locking or unlocking operation was performed with the motor, knob or key.

[0008] According to the translation of the abstract available at Espacenet, EP 0676518 A2 describes a lock assembly comprising a key-driven shaft rotatable by a key and a lock drive shaft coupled to a locking bolt for driving the locking bolt into the locking and unlocking positions. The assembly also includes an electric motor with a motor gear. Finally, the assembly includes a compliant coupling that normally couples the motor gear to the lock drive shaft to drive the locking bolt into the locking or unlocking position. The compliant coupling releases upon overload of the lock drive shaft to decouple the motor gear therefrom.The key-driven shaft is axially movable to decouple it from the motor gear, allowing the key-driven shaft to move the lock drive shaft and locking bolt into the locking or unlocking positions.

[0009] The invention is based on the object of creating a locking cylinder of the type mentioned in the introduction, in which the possibility of a motor drive is provided when using a conventional door lock.

[0010] This object is achieved according to the invention by the locking system having the features of claim 1.

[0011] According to the invention, a locking system for a door is proposed, comprising a door lock with a lock case in which a locking and / or locking mechanism is arranged and which has a cylinder perforation, an electric drive device with a drive element, a locking cylinder comprising a cylinder housing which extends in a longitudinal direction, an adjusting shaft whose axis of rotation extends in the cylinder housing in the longitudinal direction, and a lock driver which is arranged in a rotationally fixed manner on the adjusting shaft and is adjustably arranged in a recess of the cylinder housing, wherein a motor driver is arranged in a rotationally fixed manner on the adjusting shaft and is offset in the longitudinal direction relative to the lock driver,and wherein a housing of a drive device can be arranged parallel to a lock case and a cylinder hole of the lock case and a hole or recess of the housing of the drive device can be penetrated by the locking cylinder, wherein the lock driver of the locking cylinder interacts with the locking and / or locking mechanism of the door lock and the drive element of the electric drive device interacts with the motor driver of the locking cylinder.

[0012] The locking cylinder according to the invention thus comprises two drivers that are axially offset from one another and both arranged on the adjusting shaft. One of the drivers, i.e., the motor driver, can be driven by a motor unit or drive device that is offset from the lock or the lock case in the axial direction of the locking cylinder. The motor unit can thus be arranged parallel to the lock case and also has a hole or recess through which the locking cylinder extends.

[0013] In a preferred embodiment of the locking cylinder according to the invention, the cylinder housing comprises a second recess in which the motor driver is adjustably arranged. The adjustment shaft, on which the lock driver and the motor driver are arranged, is located in the area between the two recesses, preferably within the cylinder housing.

[0014] The locking cylinder according to the invention can be a double cylinder that can be manually operated from two sides using an actuating means, for example, a key or a knob. However, it can also be a half cylinder that can be operated from only one side using an actuating means.

[0015] In particular, if the manual actuating means for the locking cylinder is a key, the locking cylinder preferably has a cylinder core which can be rotated in the cylinder housing and which can be connected in a rotationally fixed manner to the adjusting shaft, in particular via a coupling, in order to rotate the adjusting shaft.

[0016] When the clutch is decoupled, the adjustment shaft can rotate freely relative to the cylinder housing. This condition occurs when no actuating device is inserted into the cylinder core. This results in a so-called "freewheel function." The adjustment shaft, together with the lock driver and the motor driver, can then rotate freely. This freewheel function is necessary so that the motor unit can actuate the adjustment shaft via the motor driver and thus the lock via the lock driver.

[0017] If the locking cylinder according to the invention is a double cylinder, it is conceivable that it is composed of two half cylinders, whose lock drivers are connected to each other via a connecting pin that forms the adjustment shaft. One of the lock drivers then forms the motor driver, which can be driven by the motor unit outside of a door lock.

[0018] The motor driver can be designed as a cam in the manner of a conventional locking bit of a locking cylinder or can also be a gear that can be brought into engagement with a drive wheel of a motor or a gear of the drive device.

[0019] Accordingly, the lock driver can be designed as a conventional locking bit or as a gear wheel.

[0020] The locking system according to the invention thus comprises an electric drive device or an electric motor, by means of which the drive element and thus the locking cylinder can be driven to actuate the door lock. The lock case and the drive device are arranged next to one another in such a way that the locking cylinder extends through a housing of the drive device and the lock case in the area of ​​the cylinder hole. The drive device and the door lock are thus offset from one another in the axial direction of the locking cylinder and have parallel main planes.

[0021] In a preferred embodiment of the locking system according to the invention, the drive device comprises an electric motor connected to a power source. The power source can be a direct component of the locking system and can be configured as a battery, which is particularly rechargeable, i.e., as an accumulator. The battery can be arranged in the housing of the drive device.

[0022] In a further advantageous embodiment of the locking system according to the invention, a control device is provided for the electric drive device. This control device can be a switch connected to the electric drive device and by means of which it can be activated, or it can also comprise a remote control that interacts with a corresponding receiver of the electric drive device. Thus, there can be a wireless or wired connection between the control system or an actuating part of the control system and the electric drive device.

[0023] Furthermore, the invention relates to a door arrangement comprising a door leaf provided with a locking system of the type described above.

[0024] The door leaf preferably comprises a lock chamber that is open along one longitudinal edge of the door leaf and into which the door lock is inserted. The door leaf preferably comprises a recess on a large surface that borders the lock chamber and in which the drive mechanism of the locking system is arranged. The locking cylinder of the locking system can be secured to both the drive mechanism and the door lock itself via appropriate screw connections.

[0025] In order to design the door assembly according to the invention in a visually appealing manner, a key plate is preferably provided that conceals the drive device and, in particular, the recess in which the drive device is arranged. The key plate can be designed as a long plate.

[0026] Further advantages and advantageous embodiments of the subject matter of the invention can be found in the description, the drawings and the claims.

[0028] Based on the Figures 1 to 5 a door arrangement 10 is shown, which comprises a door leaf 12, which is arranged in a door frame 14, not shown in detail, and is arranged opposite the door frame 14 between a Figure 5 shown closed position and an open position not shown in detail, in which the door opening defined by the door frame is released.

[0029] In order to secure the closed position, the door arrangement 10 comprises a Figures 1 to 3A locking system 16 shown in isolation, which comprises a door lock 18 that is inserted into a lock chamber 20 formed on a longitudinal edge of the door leaf 12 and is screwed there via a face plate 22. Adjacent to the face plate 22 is a lock case 24 arranged within the lock chamber 20, which accommodates a locking and locking mechanism and is provided with a lock nut 26 and a cylinder hole 28 for actuating the locking and locking mechanism.

[0030] The locking system 16 comprises an electric drive device 30 with a drive housing 32, which is inserted into a recess 34 adjacent to the lock recess 20, offset in the direction of the axis of the cylinder hole 28 and open on a large surface of the door leaf 12. The electric drive device 30 is provided with a further cylinder hole 36. An electric motor, which drives a drive element, is arranged in the drive housing 32.

[0031] For actuation, the locking system 16 has a locking cylinder 38 which is inserted into the Figures 6 to 8 is shown in isolation and is designed as a double cylinder which can be operated from each of its two end faces by means of a key 40. The locking cylinder 38 extends through the two cylinder holes 28 and 36 of the door lock 16 and the electric drive device 30. The locking cylinder 38 is secured by screws which can be screwed on the one hand via a screw hole 42 of the electric drive device 30 into a thread 44 of the locking cylinder 38 and on the other hand via a screw hole 46 on the face plate 22 of the door lock 18 into a thread 48 of the locking cylinder 38.

[0032] The locking system 16 further comprises two panels 50 and 52 designed as long plates. The panel 50 accommodates a handle 54 on which a square 56 is arranged, which engages the lock nut 26. A knob 58 is rigidly attached to the panel 52. Both panels 50 and 52 have a cylinder opening 60. The locking cylinder 38 has a cylinder housing 62 which extends in a longitudinal direction or has a longitudinal axis and in which an adjusting shaft 64 is rotatably mounted, which can be actuated from the two end faces by means of the key 40. The key 40 can be inserted into a cylinder core 66, whereby the respective cylinder core 66 is coupled to the adjusting shaft 64. When the key 40 is not inserted, the adjusting shaft 64 is freely rotatable relative to the cylinder housing 62 and the cylinder cores 66.

[0033] The adjustment shaft 64 comprises a lock driver 68 and a motor driver 70, as well as a pin connecting the two drivers. The lock driver 68 is rotatable in a recess 72 of the cylinder housing 62. The motor driver 70 is rotatable in a recess 74 of the cylinder housing 62.

[0034] The lock driver 68 is designed as a so-called locking bit or cam and, in the assembled position, interacts with the locking and locking mechanism of the door lock 18. The motor driver 70, which is axially offset from the lock driver 68, is also designed in the manner of a locking bit or cam and can be actuated by means of the electric drive device 30, i.e., upon actuation of the electric drive device 30, an adjusting force is exerted on the motor driver 70, so that the adjusting shaft 64 is rotated and the locking and locking mechanism of the door lock 18 is actuated via the lock driver 68.

[0035] In Figure 9 An alternative embodiment of a locking cylinder 90 is shown. The locking cylinder 90 largely corresponds to that according to Figure 8 , but differs from this in that it has a lock driver 68' and a motor driver 70', each formed by a gear wheel arranged non-rotatably on the adjusting shaft 64. Otherwise, the locking cylinder 90 corresponds to that according to Figure 8 .

[0036] In Figure 10 a locking cylinder 100 is shown, which in turn is largely the same as that according to Figure 8 but differs from it in that it has a motor driver 70' which is designed as a gear. On the other hand, the lock driver 68 is designed according to the embodiment according to Figure 8 designed as a cam or locking bit. The lock driver 68 and the motor driver 70' are part of the adjusting shaft 64 and are therefore connected to each other in a rotationally fixed manner.

[0037] In the Figures 11 to 13 Lock cylinders 110, 120 and 130 are shown, each of which is designed as a double cylinder and can be operated on one side by means of a key 40 and on the other side by means of a knob 76 connected in a rotationally fixed manner to the adjusting shaft 64. Otherwise, the lock cylinder 110 corresponds to Figure 11 the one after Figure 8 , the locking cylinder 120 after Figure 12 the one after Figure 9 and the locking cylinder 130 after Figure 13 the one after Figure 10 .

[0038] In the Figures 14 to 16Each lock cylinder 140, 150 or 160 is shown, designed as a half cylinder, which has a cylinder housing 32 that accommodates an adjusting shaft 64, on which a lock driver 68 or 68' and a motor driver 70 or 70' are arranged in a rotationally fixed manner. The adjusting shaft 64 is connected to a knob 76, which represents a manually operable adjusting means. The motor driver 70 or 70' of the lock cylinders 140, 150 and 160 can be coupled to an electric drive device, which is designed in the manner of the Figures 1 to 5 shown electric drive device and is offset in the axial direction of the adjusting shaft 64 relative to a door lock, on which the lock driver 68 or 68' acts. The locking cylinder 140 according to Figure 14 has a lock driver and a motor driver, each designed as a cam or in the manner of a locking bit. The locking cylinder 150 according to Figure 15has a gear wheel as lock driver 68' and a gear wheel as motor driver 70'. The locking cylinder 160 according to Figure 16 has a gear as motor driver 70' and a cam or locking bit as lock driver 68

[0039] In the Figures 17 to 19 Further locking cylinders 170, 180 and 190 are shown, which represent further embodiments of a locking cylinder according to the invention and are each designed as a half cylinder. In contrast to the embodiments according to the Figures 14 to 16 The locking cylinders 170, 180 and 190 are each manually operable by means of a key 40 which can be inserted into a cylinder core 66, which is coupled in a rotationally fixed manner to the adjusting shaft 64 by inserting the key 40, which comprises a lock driver 68 or 68' and a motor driver 70 or 70'. Furthermore, the locking cylinder 170 corresponds to Figure 17 the one after Figure 14, the locking cylinder 180 Figure 18 the one after Figure 15 and the locking cylinder 190 after Figure 19 the one after Figure 16 .

[0040] The cylinder housings 62 of the locking cylinders described above each have a cross-section corresponding to the cross-section of a so-called Euro profile cylinder and have a substantially circular head region, followed by a downward-facing, strip-like foot region of smaller width. However, it is also conceivable for the cylinder housing to be circular, oval, or with a different cross-section.

[0041] In Figure 20An electric drive device 30 is shown, which can be used in conjunction with the above-described embodiments of locking cylinders, which have a gear as a motor driver and can be inserted into a recess in a door arrangement that is arranged adjacent to a lock recess. The drive device 30 according to Figure 20comprises a drive housing 32 in which an electric motor 78 is arranged, which drives a drive gear 82 via a gear mechanism 80. This drive gear represents a drive element that can be brought into engagement with a motor driver 70', designed as a gear, of a locking cylinder 90. The motor driver 70' is designed as a gear. Furthermore, the drive housing 32 accommodates batteries 84 as a power source for the electric motor 78, which form the power source of the drive device 30. The locking cylinder 90 extends through a cylinder hole 36 of the drive housing 32. In addition, the drive housing 32 has an elongated hole 86 through which a square of a handle can pass, which engages with a lock nut of the respective door lock.

[0042] In addition, the drive device can also have a control device 88 which can be controlled wired or wirelessly, for example via a Bluetooth interface, and which triggers an actuation of the electric motor 78. List of reference symbols
