For such a space-saving, in particular parallel arrangement is possible, a transmission is required. The transmission causes a power transmission between the drive shaft and the shaft.

On, in and / or on the shaft, a spiral or coil spring is arranged. The spiral or coil spring may be formed as any spiral or coil spring. In this case, the coil spring has several turns.

According to the invention, a driver is provided. In other embodiments, a plurality of drivers may be provided. Driver and spring interact such as threaded spindle and threaded nut and allow the transmission of a rotational movement in a translational movement. Unlike a threaded spindle, however, the spring allows preloading.

The actuator thus has a kind of spring spindle, which is driven or tensioned by a motor. The spring spindle is realized by a seated on a shaft and by engaging in the spring driver as freely movable spiral or coil spring.

This has on each side in each case a projecting from the spiral or helical shape end. At least one of the ends, preferably both ends, are not fixed, so that an at least partial axial displacement along the axis of the helical spring, and preferably also along the shaft is made possible. In one embodiment, at least one of the screw ends, preferably both ends of the screw, projects into a space that at least partially limits rotation of the ends about the axis of the spring.

In a multi-part embodiment, the slider comprises the base body and the engagement means, more precisely the slider arm or the slider arms. The slider arms can partially or completely project beyond the base body. Thus, the slider arm can be designed as a housing surrounding the slide. In other embodiments, the at least one pusher arm may be formed as a component protruding from the base body or protruding projection. The slider is designed to cooperate with the coil spring. For this purpose, the slider limits the coil spring on two sides, so that a biasing of the coil spring is possible.

The slider cooperates with the spring and transmits the resulting from the interaction movement to the actuator-side coupling part. Preferably, the slider has centrally and / or laterally at least one slide arm / locking bar and / or a tip for engagement in the corresponding coupling part of the locking mechanism.

This preferably comprises an electric motor. When the electric motor is driven, a shaft connected to the slider is driven via its drive shaft. In the slide there is a spiral or helical spring which sits on the shaft and cooperates with a arranged on the shaft driver. When the shaft rotates the spring-driver combination translates the rotational movement of the shaft in a translational movement of the slider. The slide moves thus in the axial direction with respect to the shaft back and forth. The actuator, more precisely the slider is disposed adjacent to the corresponding engagement member for engagement of the locking mechanism. By the extension and retraction of the slide and the associated coupling part engagement of the locking mechanism is ensured or repealed. For this purpose, the closing mechanism has a coupling part designed to cooperate with the slider. Actuator and coupling part of the locking mechanism thus form a coupling.

The closing mechanism 100 according to the embodiment not according to the invention is designed as a lock cylinder 200 and comprises a cylinder housing 10. In a recess of the cylinder housing 10, a closing lug or a closing lever 9 is rotatably arranged about an axis of rotation. Further, in the lock cylinder 200, a first sliding bearing 11 is provided. This is designed as a bush, which is formed of a suitable material, which differs from the material for the cylinder housing 10. The actuator 150 overlaps the first slide bearing 11. More specifically, the slide bearing 11 is seated on the housing 70 in which the actuator 150 is disposed. The actuator 150 includes a motor 6. The motor 6 has a drive shaft 6a, which has a toothing in the form of a pinion 1. In meshing with the pinion 1 in engagement, a toothing 2b of a shaft 2a is provided. The toothing 2b is also formed as a gear. The shaft 2a has a driver 2c. The driver 2c is arranged approximately centrally on the shaft 2a and protrudes radially from this. The driver 2c is designed to engage in a gap 5a of two adjacent turns 5b of a coil spring 5. The coil spring 5 is seated coaxially on the shaft 2a. Shaft 2a, toothing 2b and driver 2c are referred to as worm 2. Coil spring 5 and screw 2 act together with a slider 3. In this case, the slider 3 has a lateral boundary, which is formed by corresponding side walls 3a, which define an interior 3b of the slider 3. In this case, the shaft 2a extends through two axially opposite side walls 3a, that the driver 2c and located on the shaft 2a coil spring 5 are arranged in the interior 3b. The shaft 2a leads via corresponding guides, here as Recesses 3 c or recordings are formed, the slide 3 and is stored or recorded there. The coil spring 5 has at its ends respectively a radially projecting spring end 5c. The spring ends 5 c are not fixed in the slider 3. Rather, the coil spring 3 can be at least partially rotated or rotated about the axis and / or moved in the axial direction. The spring ends 5 c can limit a rotational movement of the coil spring 5 by abutment against the lateral side walls 3 a. Laterally on the slide 3, an arm in the form of a locking bar 4 or Schieberarms is provided on each side. This projects in each case in the axial direction forward over a front side wall 3a 'of the slider 3 in the direction of closing lever 9. Accordingly, the locking bar 4 are provided for engagement in the adjacently arranged closing lever 9, which has corresponding engagement possibilities for this purpose. Motor 6, pinion 1, screw 2, slide 3, locking bar 4 and coil spring 5 are arranged in a housing 70. The housing 70 is cylindrical with two semi-cylindrical housing halves 7 and 8 is formed. These have at their respective inner wall corresponding projections for receiving at least some of the aforementioned components. A second sliding bearing 12 is provided axially opposite to the first bearing 11 at least partially overlapping the housing 70. For actuating the lock cylinder 100, a door or rotary knob 50 is provided. This axially delimits the lock cylinder 200 at one (as shown) or both ends (not shown).

The actuator 150 is provided for actuating a door lock (not shown here). The motor 6 is designed as an electric motor. This drives the shaft 2a, either directly or via an intermediate gearbox. The transmission here comprises the pinion 1 and the toothing 2b designed as a gear. On, in and / or on the shaft 2a, the coil spring 5 is arranged. The shaft 2a engages with its driver 2c in at least one gap 5a between two adjacent turns 5b of the coil spring 5, whereby a rotation of the shaft 2a, the coil spring 5 moves axially. The coil spring 5 engages the slider 3, so that an axial displacement of the coil spring 5 biases the slider 3 at least in the direction corresponding to a displacement. In this case, the coil spring 5 is at least partially axially displaceable relative to a stator of the motor 6, in and / or arranged on the shaft 2a. The spring ends 5c are not clamped stationary, but arranged freely. The driver 2c is formed as an external thread 2d extending at least partially circumferentially around the shaft 2a and / or on the shaft 2a. The profile of the external thread 2d may be of any desired design, for example as involute, rectangular, triangular or the like. In particular, the external thread 2d is suitable Engaged in the intermediate space of the coil spring 5 is formed. The motor 6, more precisely the electric motor 6, has the drive shaft 6a in addition to a stator. About the drive shaft 6a, the shaft 2a is driven. The shaft 2a is preferably offset, either transversely or as here offset parallel to the drive shaft 6a. As a result, a small-sized arrangement can be realized. To drive the shaft 2a, a reversal of the torque is required. This is preferably done via a deflection and / or transmission gear. The torque is correspondingly deflected and / or transmitted or translated via a transmission connected between shaft 2a and drive shaft 6a or motor 6. The drive shaft 6a has a toothing here in the form of the pinion 1. The shaft 2a has the toothing, here in the form of a meshing with the pinion gear 1 on. Pinion 1 and gear thus form the transmission. For a small-sized and easily installable embodiment of the actuator 150, the housing 70 is provided, in which at least the slide 3 is taken in a translationally guided. The slide 3 has for engagement with the closing lever 9 laterally at least one slide arm / locking bar 4. The slider arm 4 is connected to the base body via a projection on the base body of the slider. In particular, the front end 4 a of the locking bar 4 is designed to engage with a corresponding part of the closing mechanism 100, more precisely the lock cylinder 200.

The lock cylinder 200 is designed as an electromechanical lock cylinder 200. This is part of a lockable via a clutch and / or releasable locking mechanism 100. The clutch comprises the actuator 150, which makes an engagement of the locking mechanism 100 and / or releases. The locking mechanism 100 has a coupling part, which is designed to cooperate with the slider 3 for releasing and / or locking the locking mechanism 100. The coupling part is formed here integrated into the locking lug 9 of the locking mechanism 100. Further, a hollow cylinder is provided, which is formed axially to an axis of rotation of the locking lug 9 adjacent thereto, wherein the actuator 150 is disposed in the hollow cylinder. The hollow cylinder thus acts as a housing 70. The slide 3 is at least partially out and / or in at an adjacent to the closing lug 9 end of the hollow cylinder out of this, so that the slide 3, more precisely the corresponding coupling part - here the locking bar 4 - in engagement can be brought with the locking lug 9 and the corresponding coupling part.

The locking mechanism 100 is intended for use in an electromechanical lock cylinder 200 or in an electromechanical door lock. The electromechanical door lock comprises the electrically and / or electromechanically operable locking mechanism 100, which can be locked and / or released via the coupling. The coupling has the actuator 150. The slider 3 of the actuator 150, more precisely the locking bar 4 and more particularly the front end 4a of the locking bar, is disposed adjacent to the coupling portion of the locking mechanism 100 and is engageable by actuation of the actuator or actuator 150 therewith. Thus, the actuator 150 and / or the lock mechanism 100 formed as a lock cylinder 200 can be used with the actuator 150 in the lock mechanism 200 and the electromechanical lock, respectively.

Because the actuator 150 can be accommodated in the hollow-cylindrical housing 70, lock cylinders 200 or electromechanical door locks can be equipped or produced with the actuator 150 according to the invention in a simple manner.

The operation of the actuator 150 and the locking mechanism 100 can be connected to the Figures 2 and 3 and 5 and 6 recognize well. In the respective embodiments, the actuator 150 is shown in a retracted position and in an extended position, respectively. The Figures 2 and 5 show the extended position. The Figures 3 and 6 show the retracted position.

In Fig. 2 the actuator 150 is in an extended position. That is, the front ends 4 a of the locking bars 4 protrude beyond a front end 70 a of the housing 70, so that these front ends 4 a can engage in the coupling part, more precisely the coupling part integrated in the closing lever 9. As a result, a coupling of locking bar 4 and closing lever 9 is effected, so that upon actuation of the door knob 50, the closing lever 9 is rotated. When installed in a door, this can thus be opened or locked. A spin is prevented by the intervention. The retraction of the front end 4a of the locking bar 4 is effected in that the driver 2c by rotation of the shaft 2a, the entire spiral or coil spring 5 moves toward the front end of the housing 70, so that the spring 5 stretched between a front side wall 3a 'of Slider 3 and the driver 2 c on the shaft 2 a is arranged. For by the engagement of the driver 2c in the space or space 5a of two turns 5b and rotation of the driver 2c on the shaft 2a, the rotational movement of the shaft 2a in Translates a translational movement of the coil spring 5. The coil spring 5 moves in the direction of the front side wall 3a 'along the shaft 2a and is thereby compressed or tensioned. The tension causes the entire slider 3 together with the locking bar 4 to move in the direction of the front end 70a. The slider 3 is thus movable relative to the translationally stationary shaft arranged 2a, so that the slider 3 moves relative to the shaft 2a, in particular can be moved.

Fig. 3 shows the actuator 150 in a retracted position. Again, the coil spring 5 is shown in a tensioned state. However, the coil spring 5 is stretched between one of the front side wall 3a 'opposite rear side wall 3a''of the slider 3 and the driver 2c, by a corresponding rotational movement, the coil spring 5 has in the opposite direction Fig. 2 moved and tense. By the tension of the slider 3 is moved to the retracted position. Thus, the spokes 4 move back towards the housing interior. Accordingly, the front ends 4 a of the locking bar 4 no longer project beyond the front end 70 a of the housing 70. A coupling of the actuator 150 with the closing lever 9 is hereby canceled.

Fig. 4 shows an embodiment of a locking mechanism 100 according to the invention.

In the illustrated embodiment of a locking mechanism 100, an embodiment of an actuator 150 according to the invention is provided. The locking mechanism 100 comprises a coupling which has two coupling parts, an actuator-side coupling part and a complementary coupling part. The actuator-side coupling part is designed as a locking bar 4 or slide arm 4. The arm 4 or blocking bar 4 is connected here to the bridge-like slide 3. In this case, the arm 4 is not eccentric laterally on lateral side walls 3a of the slider 3 but is formed like a box. In the housing, the bridge-like slide 3 is provided in the assembled state. The coupling part, here the slide arm 4, has approximately centered on a front side integrated with a tip 4e, which is designed to engage in the corresponding coupling part. The coupling part is formed in this embodiment as a separate, box-like slide arm 4, which is connected to the bridge-like slide. The box-like slide arm 4 has an inner space in which the bridge-like slide 3 is arranged or in the assembled state. The interior is limited by corresponding walls. On a front wall, ie adjacent to a complementary coupling part, the tip 4e is integrally formed in the box-like slide arm 4. The slider 3 is inventively designed as a bridge-like slide 3 with two lateral walls, which are bridged by a bridge section like a bridge. This is used to interact with the locking bar 4 in the free space. In this case, the bridge-like slider 3 walls 3a. The front side wall 3a 'and the rear side wall 3a "each have a receptacle 3c designed as a slotted passage opening, through which the shaft 2a protrudes in the assembled state The passage openings are dimensioned such that the shaft 2a passes through them with play, preferably without contact Accordingly, the inner diameter of the receptacles 3c is larger than the outer diameter of the shaft 2a, which reduces disturbances in operation.The spring 5 and the cam 2c are arranged between the two side walls 3a ', 3a "in the assembled state. In a rotational movement of the shaft 2a, the slider 3 together with the locking bar 4 is biased due to the interaction with the coil spring 5 and moved accordingly.

The in 4 to 6 illustrated actuator 150 further comprises the motor 6, more precisely the electric motor 6. The motor 6 has the drive shaft 6a, which has a toothing in the form of the pinion 1. The pinion 1 is here formed with a magnet, more precisely a permanent magnet 1a. Via the magnet 1a, a rotational movement of the drive shaft 2a can be detected via a sensor (not shown here). In meshing with the pinion 1 in engagement, a toothing 2b of the shaft 2a is provided. The toothing 2b is also formed as a gear. The shaft 2a has the driver 2c. The driver 2c is arranged approximately centrally on the shaft 2a and protrudes radially from this. The driver 2 c is designed for engagement in the intermediate space 5 a of two adjacent turns 5 b of the coil spring 5. The coil spring 5 is seated coaxially on the shaft 2a. Shaft 2a, toothing 2b and driver 2c are referred to as worm 2. Coil spring 5 and screw 2 act together with the slider 3. In this case, the slider 3 has a lateral boundary, which is formed by corresponding side walls 3a, which define the interior 3b of the slider 3. In this case, the shaft 2a extends to two axially opposite side walls 3a, that the driver 2c and located on the shaft 2a coil spring 5 are arranged in the interior 3b. The slide 3 has corresponding receptacles 3c, which are formed here as slotted passage openings. Through this protrudes rotatably in the assembled state, the shaft 2a. The Coil spring 5 has at its ends in each case a radially projecting spring end 5c. The spring ends 5c are not rotationally fixed in the slider 3. Rather, the coil spring 3 can be at least partially rotated about the axis or shaft 2a and / or axially displaced. The spring ends 5 c can limit a rotational movement of the coil spring 3 by abutment against the lateral side walls 3 c. Here, the helical spring 5 is delimited in the axial direction by the side walls 3a ', 3a "of the bridge-shaped slider 3, so that the helical spring 5 is bridged over like a bridge 12. The shaft 2a is correspondingly rotatably arranged to the bridge-like or bridge-shaped slider 3. The bridge-like embodiment supports this Clamping of the helical spring 5 in the corresponding position The slider bar 4 is arranged around the slider 3, whose front end 4a is integrated in the form of a tapered tip 4. The function corresponds approximately to the locking bar 4 or its front end 4a according to the embodiment after Fig. 1 to 3 , The tip 4e protrudes in the axial direction in the direction of the complementary coupling part 15. The complementary coupling part 15 is integrally formed here integrally formed in a ring 16 of the locking mechanism 100. The actuator 150 has the housing 70, in which the aforementioned components are received, analogous to the embodiment according to Fig. 1 to 3 , The housing 70 is also designed in several parts, wherein the housing 70, the two - here non-cylindrical - housing halves 7, 8 includes. Furthermore, the coupling electronics 17 for the actuator 150 are still provided in the housing. Such a coupling electronics 17 can also according to the embodiment Fig. 1 to 3 be provided, but is not shown there explicitly.

The actuator 150 is provided for operating a closing mechanism 100, here a closing mechanism 100 for an electromechanical door lock (not shown here). The motor 6 is designed as an electric motor. This drives the shaft 2a, either directly or via an intermediate gearbox. On, in and / or on the shaft 2a, the coil spring 5 is arranged. The shaft 2a engages with its driver 2c in at least one gap 5a between two adjacent turns 5b of the coil spring 5, whereby a rotation of the shaft 2a, the coil spring 5 moves axially. The coil spring 5 engages the slider 3, so that an axial displacement of the coil spring 5 biases the slider 3 at least in the direction corresponding to a displacement. The driver 2c is formed as an external thread 2d extending at least partially circumferentially around the shaft 2a and / or on the shaft 2a. The profile of the external thread 2d can be formed arbitrarily, for example as involute, rectangular, triangular or the like. In particular, the external thread 2d is formed for suitable engagement in the clearance of the coil spring 5. The motor 6, more precisely the electric motor 6, has the drive shaft 6a in addition to a stator. About the drive shaft 6a, the shaft 2a is driven. The shaft 2a is preferably offset, either transversely or as here offset parallel to the drive shaft 6a. As a result, a small-sized arrangement can be realized. To drive the shaft 2a, a reversal of the torque is required. This is preferably done via a deflection and / or transmission gear. The torque is correspondingly deflected and / or transmitted or translated via a transmission connected between shaft 2a and drive shaft 6a or motor 6. The drive shaft 6a has a toothing here in the form of the pinion 1. The shaft 2a has the toothing, here in the form of a meshing with the pinion gear 1 on. Pinion 1 and gear thus form the transmission. For a small-sized and easily installable embodiment of the actuator 150, the housing 70 is provided, in which at least the slider 3, more precisely the locking bar 4, is received translationally received. The slide 3 has a tip 4e for engagement with the ring 16 or the coupling part 15. The locking bar 4 is generally configured for engagement with a corresponding locking mechanism 100.

In Fig. 5 For example, the actuator 150 is shown in an extended position. The actuator 150 is analogous to Fig. 2 in an extended position. That is, a front end 4a of the locking bar 4 or here the tip 4e projects beyond a front end 70a of the housing 70, so that this front end 4a can engage in the coupling part 15, more precisely in the coupling part 15 integrated into the ring 16. As a result, a coupling of locking bar 4 and ring 16 is effected. When installed in a door, this can thus be opened or locked. A spin is prevented or enabled by the intervention. The retraction of the front end 4a of the locking bar 4 and the tip 4e is effected by the driver 2c by rotation of the shaft 2a, the entire spiral or coil spring 5 moves toward the front end 70a of the housing 70, so that the spring 5 stretched between a front side wall 3a 'of the slider 3 and the driver 2c is arranged on the shaft 2a. For by the engagement of the driver 2c in the space or space 5a of two turns 5b and rotation of the driver 2c via the shaft 2a, the rotational movement of the shaft 2a is translated into a translational movement of the coil spring 5. The coil spring 5 moves toward the front side wall 3a along the shaft 2a and becomes while compressed or stretched. The tension causes the entire slider 3 together with the tip 4e to move towards the front end 70a. The shaft 2a is mounted in the housing 70. The slider 3 is thus at least displaceable relative to the shaft 2a. The function is analogous to the first embodiment.

Fig. 6 shows the actuator 150 in a retracted position. Again, the coil spring 5 in a tensioned state. Analogous to Fig. 3 the helical spring 5 is stretched between the rear side wall 3a '' of the slider 3 and the driver 2c, by a corresponding rotational movement the helical spring 5 has moved in the opposite direction compared to Fig. 5 moved and was strained. By the tension of the slider 3 is moved to the retracted position. Thus, the tip 4e moves back towards the housing interior. Accordingly, the tip 4e of the slider 3 no longer projects beyond the front end 70a of the housing 70. A coupling with the ring 16 is hereby repealed.
