Description

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.

Various locking cylinders are known from the prior art, which are used in conjunction with a door lock and are used to operate it. For this purpose, the respective lock cylinder is inserted into a cylinder hole which is formed on a lock case of the door lock. The lock cylinder comprises a cylinder housing which extends in a longitudinal direction and which has a core into which a key can be inserted and which can establish a rotation-proof connection to a lock bit via a coupling, which can be pivoted in a recess in the cylinder housing and which has a lock driver represents, which transmits an adjustment force exerted by the key to a closing and locking mechanism of the door lock. By actuating the lock bit, the closing and locking means of the door lock, such as a latch, a bolt, a secondary bolt and/or the like, are actuated. The locking cylinder is usually designed as a so-called double cylinder, i.e. h, it has a core in the cylinder housing on both sides into which a key can be inserted in order to operate the locking bit and thus the locking and locking mechanism of the door lock. So-called half-cylinders are also known, which are only provided with a core on one side for inserting a key. In addition, so-called knob cylinders are known, in which a knob is permanently mounted on the core, which represents a handle for the locking cylinder. The knob allows key-free operation of the door lock in question. It is also known to provide a double cylinder with a knob on one side and a core for inserting a key on the other side.

The lock bit or lock driver is usually designed in the manner of a locking lug, which is received in the recess of the cylinder housing in a certain rotational position, so that the lock cylinder can be inserted into the cylinder perforation of the lock case without resistance. The lock cylinder is fixed to the lock case using a screw that is screwed in from a faceplate of the mortise lock at right angles to the axis of the cylinder housing.

The lock cylinder of the type described above is operated exclusively via a key or a knob. There is no additional or alternative drive option using a motor or the like.

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 given when using a conventional door lock.

This object is achieved according to the invention by the locking cylinder with the features of claim 1.

According to the invention, a lock cylinder for a door is proposed, comprising a cylinder housing which extends in a longitudinal direction, an adjusting shaft whose axis of rotation extends in the longitudinal direction in the cylinder housing, and a lock driver which is arranged in a rotationally fixed manner on the adjusting shaft and in a recess of the Cylinder housing is adjustable. A motor driver is arranged on the adjusting shaft in a rotationally fixed manner and is offset in the longitudinal direction relative to the lock driver.

The lock cylinder according to the invention therefore comprises two drivers which are axially offset from one another and are both arranged on the adjusting shaft. One of the drivers, ie the motor driver, can be driven by a motor unit or drive device which is offset from the lock or from the lock case of the lock in the axial direction of the lock cylinder. The motor unit can therefore be arranged parallel to the lock case and also have a hole or recess through which the lock cylinder passes.

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 adjustable. The adjustment shaft, on which the lock driver and the motor driver are arranged, lies in the area between the two recesses, preferably within the cylinder housing.

The lock cylinder according to the invention can be a double cylinder which can be operated manually from two sides by means of an actuating means, for example by means of a key or a knob. But it can also be a half cylinder that can only be actuated from one side using an actuating means.

In particular, if the manual actuation 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, to the adjusting shaft.

When the clutch is decoupled, the adjusting shaft can be freely rotated relative to the cylinder housing. This condition occurs when no actuating means is inserted into the cylinder core. This creates a so-called “freewheeling function”. The adjustment shaft with the lock driver and the motor driver can then rotate freely. This freewheeling function is required so that the motor unit can operate the adjusting shaft via the motor driver and thus the lock in question via the lock driver.

If the lock cylinder according to the invention is a double cylinder, it is conceivable that it is composed of two half cylinders, the lock drivers of which are connected to one another 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.

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 gearbox of the drive device.

In a corresponding manner, the lock driver can be designed as a conventional locking bit or as a gear.

The invention also relates to a locking system for a door, comprising a door lock with a lock case in which a locking and/or locking mechanism is arranged and which has a cylinder perforation. In addition, an electric drive device with a drive element and a locking cylinder of the type described above are provided. The lock driver of the lock cylinder interacts with the locking and/or locking mechanism of the door lock. The drive element of the electric drive device interacts with the motor driver of the lock cylinder.

The locking system according to the invention therefore comprises an electric drive device or an electric motor, by means of which the drive element and thus the lock cylinder can be driven to operate the door lock.

The lock case and the drive device are preferably arranged next to one another in such a way that the lock cylinder passes through a housing of the drive device and the lock case in the area of the cylinder perforation. The drive device and the door lock are therefore offset from one another in the axial direction of the locking cylinder and have main planes aligned parallel to one another.

In a preferred embodiment of the locking system according to the invention, the drive device comprises an electric motor which is connected to a power source. The power source can be a direct part of the locking system and can be designed as a battery, which is in particular rechargeable, i.e. H. is designed as an accumulator. The battery can be arranged in the housing of the drive device.

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 that is connected to the electric drive device and by means of which it can be activated, or can also include a remote control that is connected to a corresponding receiver of the electric drive device interacts. There can therefore be a wireless or a wired connection between the control or an actuating part of the control and the electric drive device.

Furthermore, the invention relates to a door arrangement which comprises a door leaf which is provided with a locking system of the type described above.

The door leaf preferably comprises a lock space which is open on a longitudinal edge of the door leaf and into which the door lock is inserted. On a large area, the door leaf preferably comprises a recess which borders on the lock space and in which the drive device of the locking system is arranged. The locking cylinder of the locking system can be secured via appropriate screw connections both on the drive device and on the door lock itself.

In order to design the door arrangement according to the invention in a visually positive manner, a key plate is preferably provided which covers 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.

Further advantages and advantageous refinements of the subject matter of the invention can be found in the description, the drawing and the claims.

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

In order to be able to secure the closed position, the door arrangement 10 includes a Figures 1 to 3 locking system 16 shown alone, which includes a door lock 18 which is inserted into a lock space 20 formed on a longitudinal edge of the door leaf 12 and is screwed there via a cuff 22. The forend 22 is adjoined by a lock case 24 arranged within the lock space 20, which accommodates a locking and locking mechanism and is provided with a lock nut 26 and a cylinder perforation 28 for actuating the locking and locking mechanism.

The locking system 16 includes an electric drive device 30 with a drive housing 32, which is inserted into a recess 34, which is offset adjacent to the lock recess 20 in the direction of the axis of the cylinder hole 28 and is open on a large area of the door leaf 12. The electric drive device 30 is provided with a further cylinder perforation 26. An electric motor which drives a drive element is arranged in the drive housing 32.

For actuation, the locking system 16 has a locking cylinder 38 which is in the Figures 6 to 8 is shown alone and is designed as a double cylinder can be operated from each of its two end faces by means of a key 40. The locking cylinder 38 passes 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, on the one hand, pass through a screw hole 42 in 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 faceplate 22 of the door lock 18 can be screwed into a thread 48 of the lock cylinder 38.

The locking system 16 further includes two panels 50 and 52 designed as long shields. The panel 50 accommodates a handle 54 on which a square 56 is arranged, which passes through the lock nut 26. A knob 58 is rigidly attached to the panel 52. Both apertures 50 and 52 have a cylinder opening 60.

The lock 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 relevant cylinder core 66 is coupled to the adjusting shaft 64. When the key 40 is not inserted, the adjusting shaft 64 can be freely rotated relative to the cylinder housing 62 and the cylinder cores 66.

The adjusting shaft 64 includes a lock driver 68 and a motor driver 70 and a pin that connects the two drivers together. The lock driver 68 can be rotated in a recess 72 in the cylinder housing 62. The motor driver 70 can be rotated in a recess 74 in the cylinder housing 62.

The lock driver 68 is designed as a so-called locking cam or cam and interacts with the locking and locking mechanism of the door lock 18 in the assembly position. 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, that is, when the electric drive device 30 is actuated, an adjusting force is exerted on the motor driver 70, so that the adjusting shaft 64 rotated and the locking and locking mechanism of the door lock 18 is actuated via the lock driver 68.
