Description

The present invention relates to a rotary knob for actuating a cylinder adapter of a lock cylinder. Another aspect of the present invention relates to a lock cylinder comprising such a knob.

Such rotary knobs are well known. In particular, mechatronic rotary knobs are known, by which a cylinder adapter of a lock cylinder can be unlocked from a door page only after previous authentication. The authentication can be done for example by means of a chip or an ID card.

Without such authentication, the knob is decoupled from the cylinder adapter. Therefore, turning the knob does not result in rotation of a closing member of the cylinder adapter, and thus the door can not be opened.

However, if there is an authorization to open the door via an authentication, a coupling slide is brought into positive engagement with a coupling element via a drive, which may be, for example, a motor, so that a torque applied to the rotary knob via the coupling slide and the positively connected Coupling element is transmitted to the closing element of the cylinder adapter.

Here, the drive is arranged directly in a holder in the knob. However, this has the disadvantage of a complicated and complex assembly due to tight space conditions. Furthermore, the drive can also be difficult to replace be, if at all possible, without having to destroy the knob. Furthermore, the bracket and thus also the rotary knob must be adapted to the size of the drive in different applications. This can lead to increased costs and a large number of knobs, which must be kept as a stick.

It is therefore an object of the present invention to provide a rotary knob with an improved arrangement of a drive in the knob.

• einen Grundkörper mit einer ersten Halterung,
• einen Antrieb,
• einen Kupplungsschieber, welcher vom Antrieb antreibbar ist, um den Drehknauf von einem entkoppelten Zustand in einen gekoppelten Zustand zum Betätigen des Zylinderadapters zu bringen, und
• eine Antriebstasche, in welcher der Antrieb angeordnet ist, und welche in die erste Halterung einschiebbar ist.

According to the invention, this object is achieved by a rotary knob for actuating a cylinder adapter, comprising:

• a main body with a first holder,
• a drive,
• a coupling slider which is drivable by the drive to bring the rotary knob from a decoupled state to a coupled state for actuating the cylinder adapter, and
• a drive pocket, in which the drive is arranged, and which is insertable into the first holder.

Through this knob results in a variety of benefits. In particular, by the presence of a drive pocket, in which the drive is arranged, and which is inserted into the first holder, the assembly or disassembly of the rotary knob can be simplified. For this purpose, the drive can be used outside of the knob in the drive pocket and thus the drive and the drive pocket can serve as a preassembled module, which is then used in a simple manner in the knob. Furthermore, it can be ensured that the drive is inserted with the correct orientation into the first holder. Thus, potential assembly errors can be eliminated. Thus, for example, a fitter can insert the drive pocket with the drive approximately like a drawer into the first holder of the base body. Furthermore, the drive pocket serves as a storage for the drive, whereby the forces resulting from the drive are not transmitted directly to the body. This creates a pleasant for the user Operating feeling of the knob. Furthermore, the drive in the drive pocket is protected from dirt or particles. In addition, a cable of the drive can also be securely arranged in the drive pocket. Furthermore, the drive pocket serves as an additional hurdle for potential burglars, making manipulation of the drive difficult or can be prevented.

The dependent claims contain advantageous developments and refinements of the invention.

Preferably, the base body may be at least partially hollow cylindrical and have a lateral surface, wherein the first holder is disposed on an inner side of the lateral surface. Due to the shape of the base body, the arrangement of the first holder can be provided in the rotary knob. In particular, the base body has a longitudinal axis, in particular a central axis, wherein the first holder is formed with the largest possible distance from the longitudinal axis. By arranging the first holder on the inside of the lateral surface, an engagement point of the coupling slide can be made possible with a coupling element with a large effective radius. Due to the large effective radius, the corresponding forces, e.g. at a transmission of torques, be kept relatively small. Thus, e.g. the coupling slide and the coupling element are made compact and lightweight. In addition, the coupling slide can be accelerated quickly, whereby short coupling and decoupling times can be realized. Thus, a user can quickly unlock the lock cylinder and open the door. Then, the coupling slider can quickly return to its decoupled state in which access is prevented without new authentication.

Particularly preferably, the drive pocket can have a shape substantially complementary to a shape of the first holder, wherein in particular the first holder is rotationally asymmetrical. Due to the mutually complementary shapes of the first holder and the drive pocket is a stable arrangement of the drive pocket in the first Holder allows. Furthermore, the forces generated by the engine can be transmitted via the drive pocket substantially uniformly to the first holder.

Further preferably, the drive pocket can be formed rotationally asymmetrical, whereby the orientation of the drive pocket in the first holder is predetermined in the insertion direction. In particular, the drive pocket may preferably have an L-shaped cross section.

Advantageously, the rotary knob may further comprise a second holder, in which the coupling slide can be inserted simultaneously with the drive pocket, wherein in particular the second holder is provided on the inside of the lateral surface. Thus, the second bracket carries at least a portion of the weight of the coupling slide, which is connected to the drive shaft of the drive, in the decoupled state. This can be avoided that the motor shaft is loaded with the full weight of the coupling slide. In addition, the coupling slide can be mounted in the second holder, whereby the forces exerted on the coupling slide via a coupling element counter forces are absorbed in the coupled state of the coupling slide. The insertability of the coupling slide offers the advantage of easy installation. By the simultaneous insertion of the coupling slide and the drive pocket in the second holder and in the first holder, the assembly steps are reduced and, accordingly, the assembly time is shortened. Furthermore, the drive can be pre-assembled with the coupling slide outside the main body of the knob, which facilitates the entire assembly of the knob. Furthermore, the arrangement of the second holder on the inside of the lateral surface of the base body allows a compact and lightweight construction of the various components. In particular, the second holder can preferably be arranged in the radial direction farther away from a longitudinal axis, in particular a central axis, of the main body than the first holder. In this case, the second holder may preferably be arranged directly on the inside of the lateral surface of the base body. Thus, an even more compact construction of the Coupling slide allows. In this case, the coupling slide advantageously at least partially has a shape substantially complementary to a shape of the second holder.

It may also be advantageous if the coupling slide in the second holder is displaceable in the direction of a longitudinal axis of the main body. Thus, the second holder can serve as a guide for the coupling slide, wherein the coupling slide between a decoupled state and a coupled state is slidably disposed.

Preferably, the rotary knob may have a threaded spindle, which can convert a rotational movement of the drive into a linear movement of the coupling slide. In particular, preferably, the threaded spindle can be glued to a shaft of the drive. Thus, a simple rotationally fixed connection between the drive and the threaded spindle is provided.

Further preferably, the threaded spindle can be positively connected by means of a connecting element with the coupling slide. The connecting element may preferably be formed as a driver, which is rotatably connected to the threaded spindle, and causes the movement of the coupling slide when the drive drives the threaded spindle. In particular, the driver may be screwed onto the threaded spindle.

The coupling slide may preferably have a coupling slide recess, in which the driver is arranged. In particular, the driver may have a first disk-shaped region, which has a shape substantially complementary to a shape of the coupling slide recess. Thus, a rotationally fixed arrangement of the driver is made possible in the Kupplungsschieberausnehmung. Further, the driver can be arranged with play in the coupling slide recess to compensate for misalignment between the coupling slide and the driver.

Furthermore, the drive pocket may have a drive connector holder in which a drive connector, in particular with play, is arranged in order to provide electrical contact between the drive and at least one electrical component of the rotary knob. By the drive connector, a simple electrical contacting of the drive can be provided with electrical components of the body. The intended clearance compensates for potential misalignment between the drive connector and the at least one electrical component. It may also be advantageous if the drive connector is designed such that the drive connector can be used only in one orientation in the drive connector holder.

More preferably, a drive mating connector on a circuit board, in particular a first board part, be arranged, wherein the drive mating connector cooperates with the drive connector. Thus, the board can be electrically contacted with the drive in a simple manner.

It is also proposed to arrange the first board part in relation to the cylinder adapter in front of the drive, wherein in particular the first board part is partially disposed under the coupling slide. Thus, the first board part serves as manipulation protection for the drive and simplifies the electrical contact with the drive. Furthermore, a compact structure can be made possible.

Advantageously, the first board part may have a recess through which the coupling slide at least partially movable and / or in which the second holder is at least partially disposed, wherein in particular the first board part is radially fixed. Thus, a space-saving arrangement of the different components is possible. In addition, the assembly is simplified.

More preferably, the drive pocket may have a cable channel in which a cable for electrically contacting the drive with the drive connector extends. Thus, the cable is arranged protected in the cable channel.

Preferably, the drive pocket may have a drive pocket stop which limits the insertion of the drive pocket into the first holder. Thus, a movement of the drive pocket is prevented in the insertion direction and determines their final position.

It may also be advantageous if the drive pocket has at least one clip nose over which the drive pocket can be latched to the holder. Thus, the movement of the drive pocket in a direction opposite to the insertion direction can be prevented. Particularly preferably, the drive pocket on two clip noses, which are identical. In addition, the clip noses can have a resilient function.

According to a preferred embodiment of the present invention, the first holder may be formed as a passage opening or a blind opening in the base body. As a blind opening is an opening to understand that does not completely penetrate the body. The fact that the first holder is formed as an opening, can be dispensed with an additional component, thereby manufacturing costs and installation costs can be saved. The passage opening allows unlocking of the drive pocket of the first holder, wherein in the case of a blind opening further manipulation protection for the drive is provided.

It may also be advantageous if a second board part is arranged behind the drive with respect to the cylinder adapter and covers the first holder, wherein in particular the main body has a shoulder, so that the second board part is mounted at a distance from the first holder. The Arrangement of the second board part serves to protect against manipulation of the drive.

Furthermore, the present invention relates to a lock cylinder, which comprises a rotary knob according to the invention and a cylinder adapter which can be actuated by the rotary knob, wherein the drive pocket is inserted in the first holder. This is associated with the advantages mentioned above with respect to the rotary knob.

It is inventively provided that the cylinder adapter 3 is always controlled via the inner knob 4, while the knob 1 can be decoupled from a coupling unit 65 of the cylinder adapter 3, so that the knob 1 is freely rotatable. The structure of the dome unit 65 is in Fig. 2 shown.

Fig. 2 shows an exploded view of the dome unit 65. The dome unit 65 includes a drive pocket 14, in which a drive 15 is received. The drive 15 is connected to a threaded spindle 17, so that the threaded spindle 17 is rotatable by the drive 15. On the threaded spindle 17, a driver 18 is arranged so that by a rotation of the threaded spindle 17 by the drive 15 of the driver 18 is axially displaced on the threaded spindle 17 when the driver 18 is held against rotation. For rotationally fixed holding the driver 18 is arranged in a first coupling slide recess 27 of a coupling slide 16. The coupling slide 16 is again, as in Fig. 4 is shown mounted on a base body 5 of the rotary knob 1, so that only an axial displacement of the coupling slide 16 and thus of the driver 18 is made possible. In particular, a rotation of the coupling slide 16 and thus of the driver 18 is thus prevented. In this way, the coupling slide 16 is movable by the drive 15 by a rotation of the drive 15 causes a rotation of the threaded spindle 17, whereby the driver 18 is displaced on the threaded spindle 17, which is due to the arrangement of the driver 18 in the first coupling slide recess 27th affects the coupling slide 16. Thus, the coupling slide 16 is parallel to a shaft of the drive 15 and thus parallel to the threaded spindle 17 movable.

The coupling slide 16 has an engagement element 29. The function of the engagement member 29 will be described with reference to FIG Fig. 9 described. Furthermore, the coupling slide 16 may advantageously have a second coupling slide recess 28, whereby the coupling slide 16 has a very low weight. Thus, the coupling slider 16 is easy and quick to accelerate, so short shift times are guaranteed.

The drive 15 is arranged within the drive pocket 14. It is also provided that a cable for supplying the drive 15 with electrical energy in a cable channel (not shown) of the motor pocket 14 is guided. The cable of the drive 15 is threaded under the drive 15 or laterally of the drive pocket 14 and ends in a drive connector 19. To contact the drive 15, the motor pocket 14 has a drive connector holder 26. In the drive connector holder 26 of the drive connector 19 is arranged, in particular inserted from below, wherein the drive connector 19 is formed as a drive connector and connected to the cable. Thus, the drive 15 via the drive connector 19 is electrically contacted and thus controlled. For contacting the drive connector 19 is also preferably provided that the drive connector 19 is disposed with play within the drive connector holder 26 of the motor pocket 14. The electrical contacting of the drive connector 19 is in the Fig. 5 and 6 shown.

Fig. 3 shows the drive 15 with the threaded spindle 17. The drive 15 is preferably a DC motor and advantageously has a diameter of 6 mm. The threaded spindle 17 is mounted on a shaft of the drive 15, wherein a distance 200 between a housing of the drive 15 and the threaded spindle 17 is advantageously 0.3 mm to 0.5 mm. The threaded spindle 17 is in particular an M2 threaded spindle.

The dome unit 65 can be inserted into the main body 5 of the rotary knob 1. For this purpose, the main body 5, which is preferably made of metal, has a first holder 21 and a second holder 22. The first holder 21 serves to receive the drive pocket 14, while the second holder 22 serves to receive the coupling slide 16. For fixing the coupling unit 65 within the main body 5, the drive pocket 14 also has a drive stop 25, which rests after insertion of the drive pocket 14 in the first holder 21 on the base body 5. It is also provided that in this position clip projections 24 of the drive pocket 14 surround the first holder 21, so that a positive connection between the first holder 21 of the base body 5 and the drive pocket 14 of the coupling unit 65 is present. Thus, the dome unit 65 is firmly and securely locked in the main body 5.

The coupling slider 16 is disposed within the second bracket 22. Within the second holder 22, the coupling slide 16 is longitudinally displaceable, d. H. parallel to a longitudinal axis 100 of the main body 5. In particular, it is provided that the longitudinal axis 100 is arranged parallel to the shaft of the drive 15. Other movements of the coupling slide 16, in particular a rotation of the coupling slide 16, are prevented by the second holder 22.

The main body 5 has in particular a diameter of 40 mm. In this case, the main body 5 is advantageously formed as a hollow cylinder, wherein the cylindrical base body 5 has a lateral surface 20. On an inner side of the lateral surface 20, the second holder 22 is mounted, wherein the first holder 21 is disposed radially inwardly relative to the second holder 22. By attaching the second holder 22 directly to the lateral surface 20, the greatest possible radial distance between the engagement element 29 and the longitudinal axis 100 is achieved. Thus, the engagement member 29 must transmit small forces, with reference to Fig. 9 is explained.

The main body 5 also has a battery recess 23, which is formed by a first jacket opening 54. The functionality of the battery recess 23 will be described with reference to FIG Fig. 13 explained.

The first holder 21 and / or the second holder 22 may be formed as an axial passage opening of the main body 5. Advantageously, however, it is provided that both the first holder 21 and the second holder 22 are not passage openings. In this way, the first holder 21 and the second holder 22 are axially accessible only from one side. From the axially opposite side, reaching the first holder 21 and / or the second holder 22 is thus not possible. It is provided in particular that this page is the side facing away from the cylinder adapter 3. Thus, a manipulation of the coupling unit 65 and thus of the rotary knob 1 can be prevented.

The Fig. 5 and 6 show a board 10 which is disposed within the knob 1. It is provided that a first board part 57 of a first end face 51 of the base body 5 (see. Fig. 7 ) is attached to the base body 5, while a second board part 61 from a second end face 52 (see. Fig. 7 ) of the main body 5 is attached to the main body 5. Between the first board part 57 and the second board part 61, a connecting part 66 is arranged. The connecting part 66 serves for mechanically and electrically connecting the first board part 57 to the second board part 61. The connecting part 66 is designed to be completely flexible in this exemplary embodiment. Alternatively, the connecting part 66 may alternatively have a rigid portion. The first board part 57 and / or the second board part 61 are preferably rigid.

The first board part 57 in particular comprises a control and / or a regulation of the drive 15. Therefore, the first board part 57 has a drive counter-connector 56 which is formed as a contact socket and electrically connectable to the drive connector 19. If the first board part 57 is attached to the main body 5, it is provided that a Contacting drive connector 19 and drive mating connector 56 inevitably takes place. To achieve this, the first board part 57 has a recess 58 and a central bore 67. The recess 58 is used to pass the first holder 21 and the second holder 22 of the main body 5 through the first board part 57. At the same time, the first board part 57 is held rotationally fixed within the main body 5. Through the central bore 67 it is ensured that the first board part 57 is arranged centrally in the main body 5 by a positioning dome 68 of the main body 5 (see. Fig. 7 ) is guided through the central bore 67 of the first board member 57.

Furthermore, the first board part 57 has a battery mating connector 41, which is contacted by a battery compartment 8 (see. Fig. 13 ). Thus, it is provided in particular that the first board part 57 comprises all electrical components which are necessary for operating and driving the drive 15. On the other hand, the second board part 61 has all the electrical components that are required for wireless data transmission. It is thus provided in particular that the second board part 61 can communicate wirelessly with code cards which indicate whether an authorization for actuating the cylinder adapter 3 is present or not. Via the connecting part 66, the receipt of such authorization by the second board part 61 can be transmitted to the first board part 57 so that the first board part 57 controls the coupling unit 65, in particular the drive 15, in such a way that the rotary knob 1 is coupled to the cylinder adapter 3 , This is effected by a displacement of the coupling slide 16.

In order to determine in which position the coupling slide 16 is, the first board part 57 also has a first sensor 69 and a second sensor 70, the first sensor 69 and the second sensor 70 being arranged on different sides of the first board part 57. In particular, the first sensor 69 and / or the second sensor 70 are a light barrier. The light barrier is interrupted by a web 71 of the coupling slide 16, wherein, depending on the position of the coupling slide 16, the light barrier of the first sensor 69 or the light barrier of the second Sensor 70 is interrupted. Thus, it can be determined where the web 71 and thus the coupling slide 16 is located. In particular, it is distinguishable in this way, whether the coupling slide 16 is in a coupled position or in a disengaged position. A difference between the coupled position and the disengaged position will be explained with reference to FIGS Fig. 8 and 9 explained.

Fig. 7 shows the main body 5 of the rotary knob 1 with inserted board 10. The connecting part 66 is guided in a recess 64 of the body.

The first board part 57 is held by a retaining ring 13 within the base body 5. The attachment of the retaining ring 13 will with reference to Fig. 9 explained. For fixing the second board part 61 to the second end face 52 of the main body 5, two fastening means 72 are provided which engage through openings of the second board part 61. The fastening means 72 are in particular screws, preferably M2x4 pan head screws.

The 8 to 11 describe the connection of the main body 5 with a raster shaft 11. Fig. 8 shows the raster shaft 11 and a coupling shaft 12. The raster shaft 11 includes a sleeve-shaped portion having on its outer side a plurality of circumferential grooves 53. About the circumferential grooves 53, the raster shaft 11 can be fastened within the cylinder adapter 3. The interior of the sleeve-shaped region forms a recess 59 for the coupling shaft 12. Thus, the coupling shaft 12 is disposed within the raster shaft 11. Furthermore, the coupling shaft 12 is on one side by the Positionierdom 68 of the base body 5 (see. Fig. 7 ) and axially fixed on the other side by a stop 84 which bears against a flange 34 of the raster shaft 11.

Furthermore, the raster shaft 11 via the flange 34, the raster shaft 11 is connected to the base body 5. The flange 34 also has magnetic recesses 73, in which magnets 60, in particular neodymium magnets, can be used, in particular adhesively bonded. The magnets 60 are preferably flush with the flange 34. Likewise, magnets 60 are arranged on the coupling shaft 12, in particular on a flange of the coupling shaft 12, in particular in Flanschausnehmungen the coupling shaft 12. Preferably, the magnets 60 are glued into the coupling shaft 12. It can be prevented with the magnets that the driver 18, in particular the engagement element 29, collides with the coupling shaft 12.

For coupling, the coupling shaft 12 has at least one coupling nose 74. In Fig. 8 a coupling shaft 12 with two coupling lugs 74 is shown. Via the engagement element 29 of the coupling slide 16, the coupling shaft 12 can be coupled to a rotation of the main body 5 or separated from a rotation of the main body 5. The coupling slide 16 is in a coupled position, ie in a position in which the driver 18 on the threaded spindle 17 has a maximum distance to the drive 15, so is a torque of the main body 5 via the coupling slide 16 on the coupling nose 74 and thus transferable to the coupling shaft 12. In this position, a recess 79 of the raster shaft 11, in particular of the flange 34 of the raster shaft 11, ensures that the coupling slide 16, in particular the engagement element 29, does not collide with the flange 34 of the raster shaft 11. By the recess 79 is thus always a distance between the flange 34 and engaging member 29 ensured even when the coupling slide 16 is in the engaged position. However, if the coupling slide 16 is in a disengaged position, ie in a position in which the driver 18 has a minimum distance to the drive 15, then no torque can be transmitted from the base body 5 to the coupling shaft 12.

The magnets 60 prevent a colliding of the coupling slide 16, in particular of the engaging member 29 with the coupling lugs 74, by preventing by a repulsive effect of the magnets 60 of the coupling shaft 12 and the raster shaft 11 that the coupling shaft 12 remains in a position in which the coupling lugs 74 are arranged immediately in front of the coupling slide 16. Thus, said collision between the coupling slide 16th and coupling lugs 74 avoidable. The magnets are advantageously disc magnets with a dimension of 4x1 mm or 3x1.5 mm.

The coupling shaft 12 is in particular also hollow and has an inner profile with which an adapter shaft 46 (see. Fig. 17 ) of the cylinder adapter 3 is movable. To cover the coupling shaft 12 to the rotary knob 1 out, it is provided that a wave washer 75 is pressed into the hollow coupling shaft 12. In particular, the positioning dome 68 bears against the wave washer 75 in order to axially fix the coupling shaft 12.

Fig. 9 shows a combination Fig. 7 and Fig. 8 , Thus shows Fig. 9 how the raster shaft 11 and the coupling shaft 12 are connectable to the main body 5.

For aligning the raster shaft 11 with respect to the main body 5, the flange 34 of the raster shaft 11 has an alignment recess 33, while the base body 5 has an alignment nose 32. If the raster shaft 11 is connected to the main body 5, then the alignment nose 32 engages in the alignment recess 33. Thus, only one orientation of the base body 5 to the raster shaft 11 is possible for connecting the raster shaft 11 and base body 5. The Ausrichtnase 32 also serves to align the clutch shaft 12, in particular the recess 79 and the magnets 60 of the clutch shaft 12. Out Fig. 9 is also apparent that the flange 34 of the raster shaft 11, the first end face 51 of the base body 5 covers.

Fig. 10 shows the main body 5 with inserted raster shaft 11. The raster shaft 11, in particular the flange 34 of the raster shaft 11, is positively connected to the base body 5. For this purpose, in particular a flanging 76 is provided, via which the flange 34 of the raster shaft 11 is held on the base body 5.

Fig. 11 shows a sectional view of Fig. 10 , It can be seen that the flange 34 of the raster shaft 11 rests directly on the retaining ring 13. Thus is a holder of the first board part 57, in particular in the axial direction, guaranteed. The flange 34 in turn is held by the flange 76 on the base body 5.

On the side facing away from the cylinder adapter 3, the second board part 61 is arranged in a shoulder 62 of the main body 5. This makes it possible to equip the second board part 61, as well as the first board part 57, from both sides of the board surface. Thus, a maximum surface is available for equipping with electrical components.

Fig. 12 shows a retractable battery compartment 8 for the knob 1. In the battery compartment 8 is a battery 9, in particular a Tekcell CR2 lithium battery, can be used, the battery 9 is contacted by Batteriekontanten 39 of the battery compartment 8. As an alternative to the battery contacts 39, it is provided that a cable of the battery compartment 8 is soldered directly to the battery 9. In any case, a contacting of the battery 9 takes place exclusively via the battery compartment 8. The battery compartment 8 in turn has a battery connector 40, which is arranged on the battery compartment 8, in particular with play, and projects through a lateral opening of the battery recess 23 when the battery compartment 8 is inserted into the battery recess 23. The battery connector 40 is connected to the battery contacts 39 or to the soldered to the battery cable 9, so that an electrical contacting of the board 10 via the battery connector 40 takes place. How about the Fig. 5 and 6 has been described, the first board portion 57 has a battery mating connector 41 which contacts the battery connector 40 when the battery compartment 8 is inserted into the main body 5 of the rotary knob 1. The battery mating connector 41 is arranged in particular directly on the first board part 57. Here, the battery connector 40 is formed as a contact socket, wherein the battery mating connector 41 is formed as a plug. However, it is also conceivable that the battery connector 40 is a plug and the battery mating connector 41 is a contact socket.

The insertion of the battery compartment 8 in the main body 5 is in Fig. 13 shown. As already mentioned above, the main body 5 has the battery recess 23, which extends from a first jacket opening 54 to a second jacket opening 55 (cf. Fig. 11 ) and rotationally asymmetric. Alternatively, the battery recess 23 may be formed as a blind recess, ie, that the battery recess 23 does not completely penetrate the base body 5. In this case, the battery recess 23 is oriented perpendicular to the first shell opening 54 and the second shell opening 55. This allows the insertion of the battery compartment 8 through the first shell opening 54 into the battery recess 23, as in FIG Fig. 13 shown. Furthermore, an outer contour of the first casing opening 54 serves as a preliminary direction for the battery compartment 8. Furthermore, the alignment of the battery compartment 8 in the battery recess 23 in the insertion direction is predetermined by the rotationally asymmetrical design of the battery recess 23. As a result, the insertion of the battery compartment 8 in the battery recess 23 is simplified. For removing the battery compartment 8 from the battery recess 23, a force can be applied to the battery compartment 8 through the second casing opening 55, so that the battery compartment 8 can be removed from the battery recess 23 through the first casing opening 54.

As an alternative to removing the battery compartment 8 by applying a force through the second shell opening 55, the second shell opening 55 can be replaced by a spring-loaded locking mechanism. In this case, the lateral surface 20 of the main body 5, only the first shell opening 54, through which the battery compartment 8 is inserted into the battery recess 23. Subsequently, the battery compartment 8 is spring-loaded latched within the battery recess 23, so that by releasing the latch, the spring load can be used to remove the battery compartment 8 from the battery recess 23 again.

The insertion of the battery compartment 8 in the battery recess 23 is limited by a battery stop 42. The battery stop 42 is applied to a base body stop 43, when the battery compartment 8 is completely inserted into the battery recess 23. At the same time in this case the Battery connector 40 contacted by the battery mating connector 41. Thus, an automatic contact is present, so that a technician needs to insert the battery compartment 8 only in the main body 5 in order to produce both a mechanical and an electrical connection between the battery compartment 8 and main body 5.

In order to cover the first jacket opening 54 and / or the second jacket opening 55 and thus the battery recess 23 of the main body 5, different possibilities are available. In Fig. 13 it is shown that the main body 5 is surrounded by a cover 6. The cover 6 is also in together with the main body 5 in Fig. 14 shown. The cover member 6 surrounds the lateral surface 20 of the base body 5, wherein at least one peripheral opening 30 of the cover 6 allows access to the first shell opening 54 and / or to the second shell opening 55 of the base body 5. In this case, the cover 6 is in particular designed such that by a rotation of the cover 6 relative to the base 5, the first shell opening 54 and / or the second shell opening 55 of the base 5 are covered by the cover 6, ie the peripheral openings 30 of the cover 6 and the first shell opening 54 and / or the second shell opening 55 of the main body 5 are no longer aligned.

The cover 6 also serves in addition to covering the flange 76, so that the connection between the raster shaft 11 and body 5 is completely covered by the cover 6. The raster shaft 11 is guided through an end opening 31 of the cover 6.

The cover 6 may have a rib in the axial direction, which engages in a corresponding recess, in particular groove. In this way, a radial fixation is realized.

The arranged in the battery recess 23 battery compartment 8 is particularly advantageous concealable by a knob cap 7, as in Fig. 15 is shown. In this case, the battery recess 23 through the end openings 30 of Covering element 6 is always released and is only covered by the knob cap 7. It is provided that the knob cap 7 has a connecting element 38, which is designed in particular as a latching lug. With the connecting element 38, the knob cap 7 can be fastened to the main body 5. In particular, it is provided that the locking element formed as a connecting element 38 engages in the battery recess 23 and the knob cap 7 thus positively connected to the base body 5. Furthermore, it is provided that the knob cap 7 is arranged under the cover 6, that is arranged closer to the lateral surface 20 of the base body 5 than the cover 6. About a peripheral seal 35, the peripheral openings 30 of the cover 6 are closed. Overall, therefore, the cover 6 and the knob cap 7 together allow a complete and secure cover of the lateral surface 20 of the base body fifth

The knob cap 7 also has a light ring 36 which is arranged in a cover 77. The light ring 36 is glued into the knob cap 7. Alternatively or additionally, the luminous ring 36 may be clipped into the knob cap 7. The cover plate 77 covers the second end face 52 of the main body 5. For this purpose, the cover plate 77 can be used in particular in an end opening of the knob cap 7. For the design of a visually high-quality impression is also provided that on the cover plate 77 a logo aperture 78 is aufklebbar. The logo aperture 78 therefore gives the knob cap 7 and thus the knob 1 a visually high-quality impression, wherein the light ring 36 is still visible around the logo aperture 78. The light ring is in particular driven by the second board part 61. Within the cover, in particular, an RFID antenna is arranged, which is electrically connected to the second board part 61. Thus, a reading of code cards is possible. On the second board part 61, a radio antenna, in particular an 868 MHz antenna, is also arranged. This is used for communication with other components, in particular for the configuration of the rotary knob 1.

Fig. 16 shows the knob 1 with the Fig. 15 Knob cap 7 shown on mounting elements 37, both the cover 6 and the knob cap 7 with the main body 5 can be connected. These are in the mounting elements 37 advantageously to threaded pins with pins that are feasible by the cover 6 and the knob cap 7 and screwed within the main body 5.

Fig. 17 shows the cylinder adapter 3 in an exploded view. The cylinder adapter 3 comprises a closing element 45 with which a closing mechanism, for example a door, can be actuated. The cylinder adapter 3 further has adapter shafts 46, which are connected to the closing element 45. If one of the adapter shafts 46 is rotated, the closing element 45 is also rotated so that the closing mechanism of the door can be actuated by a rotation of the adapter shafts 46.

In Fig. 17 a double cylinder is shown, ie the cylinder adapter 3 can be actuated from two sides. According to the invention is also possible to use a half-cylinder, in which case the in Fig. 18 shown inner knob 4 is not needed.

The adapter shaft 46 is secured by a shaft lock 49 within the cylinder adapter 3. In addition, the adapter shaft 46 has an outer profile, which coincides with the inner profile of the coupling shaft 12. Thus, torque is transferable from the clutch shaft 12 to the adapter shaft 46. In particular, said profiles are hexagonal profiles.

About the raster shaft 11 of the knob 1 is mounted and held within the cylinder adapter 3. For holding the rotary knob 1 locking elements 47 are provided in particular. The locking elements 47 are arranged in clip sleeves 50 and are spring-loaded by a spring 48 in the circumferential grooves 53 of the raster shaft 11 is pressed. For introducing the rotary knob 1 in the cylinder adapter 3 is preferably provided that the circumferential grooves 53 of the raster shaft 11 have chamfers, so that a sawtooth on the outside of the raster shaft 11 is present. This is the knob 1 simply inserted into the cylinder adapter 3. To remove the knob 1, the locking element 47 must be pulled out of the circumferential groove 53, which causes a partial removal of the cylinder adapter 3 from the door panel. Thus, a manipulation of the lock cylinder 2 according to the invention is excluded or at least difficult. To remove the locking elements 47 with a special tool, in particular from below the cylinder adapter 3, gripped and rotated by 90 °.

By providing a large number of circumferential grooves 53 within the raster shaft 11, the rotary knob 1 is telescopic, d. H. the knob 1 can be used for cylinder adapter 3 with different lengths. Due to the adjustability of the knob 1, the knob can be adapted to different door thicknesses.

Access through a door usually only needs to be regulated from one side, since leaving the access-secured area should usually be possible at any time and for everyone. Therefore, the lock cylinder 2 according to the invention additionally has an inner knob 4, which in Fig. 18 is shown. The inner knob 4 has an inner knob body 80, which is connected via a shaft-hub connection 81, in particular by a Scheibfederverbindung, with an inner shaft 82. The inner shaft 82 has, analogous to the coupling shaft 12, an inner profile which coincides with the outer profile of the adapter shafts 46. In addition, the inner shaft 82, analogous to the raster shaft 11, circumferential grooves on the outer surface. Thus, the inner knob 4 in the same way to the cylinder adapter 3 can be attached as the knob 1. However, the inner knob 4 always allows the actuation of the cylinder adapter 3, that is, the rotation of the closing element 45th

Fig. 19 shows the final composition of the lock cylinder 2. In the in Fig. 19 As shown, a rotary knob 1 and an inner knob 4 is used for the actuation of the cylinder adapter 3. Alternatively, the invention also provides that for actuating the cylinder adapter 3, two rotary knob 1 can be used. To get a distance between the To comply with the knob 1 and the cylinder adapter 3 is finally provided a spacer 83. The attachment of the raster shaft 11 of the rotary knob 1 within the cylinder adapter 3 then takes place as in relation to Fig. 17 has been described.
