Description

Actuating device for a lock

The invention relates to an actuating device for a lock, in particular a door and / or flap lock of a motor vehicle, in particular a tractor, according to the preamble of claim 1.

Known actuators for motor vehicle locks have a handle body in which a push button with a lock cylinder is slidably mounted. The push button can be transferred from a first operating state to a second operating state and vice versa by means of a key which fits into the locking cylinder. In the first operating state, a lock can be operated by means of the push button, so that this opens. In the second operating state, the push button executes a so-called idle stroke when pressed, so that despite pressing the button, an operation, i.e. the lock is not opened. The associated motor vehicle door or motor vehicle flap is thus closed.

It is also known to lock the locks with a remote-controlled locking unit, e.g. to cooperate in a central locking system of the motor vehicle. In known arrangements of actuating device and lock together with a remote-controlled locking unit, it is disadvantageous that a large space requirement is required and that a large number of parts and a high level of structural complexity are required. Furthermore, the assembly and fastening effort of the components is complex and cumbersome.

The object of the invention is to provide an actuating device for a lock, in particular a motor vehicle door or flap lock, in particular for a tractor, which has a small footprint and has a remote-controlled locking and / or unlocking functionality.

This object is achieved with an actuating device with the features of claim 1. Advantageous embodiments are specified in the dependent claims dependent thereon.

An actuating device 1 (FIG. 1) has a handle body 2, as an actuating device a push button 3 with a locking cylinder 4, a motor-driven locking device 5, a compression spring 6 as well as a cover 7 and an actuating element 8.

When viewed from the side, the grip body 2 is formed as a substantially U-shaped grip bracket with a base leg 10, a first U leg 11 and a second U leg 12. The U-legs 11, 12 each have end faces 13 with which the handle body 2, for example on an outer door skin Motor vehicle is attachable. The second U-leg 12 has an insertion opening 15 for the printhead 3 along an actuating longitudinal axis 14 which extends in the leg direction and which is also the longitudinal movement axis of the push button 3 together with the locking cylinder 4. The insertion opening 15 opens into an insertion channel 15a, which completely penetrates the second U-leg 12. A socket-shaped receiving device 16 extends from the end face 13 of the second U-leg 12 and has an essentially cylindrical outer shape. From the insertion opening 15, an elongated groove or a blind hole recess 17 extends into it and opens outwards to approximately 2/3 of the base leg 10, which follows the course of the U-leg 12 and the base leg. The blind hole recess 17 in the base leg 10 stands in the region of its end 18 opposite the insertion opening 15 just above its groove bottom with a groove recess 19 or a groove which is opened in the opposite direction or from an inside 20 of the base leg 10 and the first U-leg 11 extends up to the end face 13 of the first U-leg 11 in connection or follows the course of these parts. The groove recess 19 can be covered or closed by means of the cover 7, which is essentially I-shaped with a first cover leg 7a and a second cover leg 7b.

The locking device 5 is designed in the manner of a plug-in module for plugging into the blind hole recess 17 of the handle body 2 and has a housing 21 with a rectangular cross section with a main housing part 22 and a lateral housing cover 23. When viewed from the side, the housing 21 is essentially L-shaped and has a first longer L-leg 24 and a shorter second L-leg 25. The first leg 24 corresponds to the blind hole recess 17 in the base leg 10. The second leg 25 corresponds to the blind hole recess 17 in the connection area of this to the insertion opening 15 and comes to lie in the assembled state in the transition area between the second U-leg 12 and the base leg 10. Electrical lines 26 go off at the free end of the first leg 24. The second leg 25 has an outer surface 27 toward the insertion opening 15, which is concavely shaped as a cylindrical section, such that the insertion opening 15 together with the outer surface 27 is circular in cross section. From the outer surface 27 of the locking device 5, a projecting slide 28, described in more detail below, protrudes a little into the insertion opening 15.

The push button 3 has a push button upper part 30 and a push button lower part 31. The locking cylinder 4 is seated in the push-button upper part 30 by means of a clip connection. On the outside of the push button upper part 30 there is a sealing ring 32 which cooperates with the inside of the insertion opening 15 and seals the gap between the push button upper part 30 and the insertion opening 15.

The structure of the push button 3, which together with the actuating element 8 forms an actuating device, together with the locking cylinder 4 will be described in more detail below with reference to FIGS. 3 and 4. The push button upper part 30 has a cylinder tube section 32a and a pressure part 33. The cylinder tube section 32a is a thin-walled cylindrical tube with a tube outside 34 and a free ring end face 35. Opposite the ring end face 35, the pressure part 33 is integrally connected to the cylinder tube section 32a. The pressure part 33 has a larger outside diameter than the cylinder tube section 32a and has a stepped bore 36 with the actuation longitudinal axis 14 as the central axis. The stepped bore 36 has longitudinal grooves 37 on the inside for receiving locking plates of the locking cylinder 4. On the outer circumference the pressure part 33 has an annular groove 38 adjacent to the cylinder tube section 32 for receiving the sealing ring 32.

The cylindrical tube section 32a has opposite rectangular window cutouts 40 with a lower edge 41, two side edges 42 and an upper edge 43. The two window sections 40 have the same area. The lower edge 41 and the upper edge 43 are each parallel to the ring end face 35. The side edges 42 are parallel to the actuation longitudinal axis 14.

The locking cylinder 4 has a locking body 50 and a rotating body 51. Locking plates 51a are mounted in the blocking body 50 in a known manner. Furthermore, the locking body 50 has a tumbler 52 as a safeguard against falling out, which is intended to prevent twisting of the locking body 50 in the pressure part 33 in a known manner. The rotating body 51 has an eccentric nipple 53 eccentrically to the longitudinal axis 14 of the actuation, which protrudes a little downward in the axial direction from the rotating body 51.

The push button lower part 31 has a stamp section 60 and a pipe section 61. The stamp section 60 has a threaded bore 63 for receiving the actuating element 8 along the longitudinal actuation axis 14 at the free end 62 of the stamp section 60. The tube section 61 has an outside diameter which corresponds to the inside diameter of the cylinder tube section 32a of the push button upper part 30. The pipe section 61 extends a little away from the stamp section 60 and, corresponding to the window cutouts 40, has latching projections 64 which are dimensioned in terms of their spatial shape in such a way that they can interact with the lower edge 41 of the window cutouts 40. With regard to the width, the locking projections 64 are dimensioned such that they are guided in the window cutouts 40 the side edges 42 are movable up and down. Adjacent to the locking projections 64, the tube section 61 has end steps 65 lying somewhat lower. The front steps 65 serve to support a slide guide 66, which is described in more detail below. Aligned in the longitudinal direction, one of the latching projections 64 has an abutment tab or abutment web 67 as an extension of the tube section 61 upwards. The stop tab 67 has a three-dimensional shape in the form of a cylindrical tube wall section and has an upper free end edge 68 and side edges 69. Directly in the longitudinal axial direction 14 adjacent to the associated latching projection 64, the stop tab 67 has an outwardly projecting, arcuate step shoulder 70 which has a step section 71 in the form of an annular section. When the push button upper part 30 and the push button lower part 31 are assembled, the step shoulder 70 is located in one of the windows 40 of the push button upper part 30 (cf. FIG. 4). The axial extent of the stop tab 67 is dimensioned such that in assembly, when the locking projection 64 bears against the lower edge 41 of the window 40, there is an axial distance between the free end edge 68 and the upper edge 43, so that a free space or gap 72 is formed is (see FIG. 4).

The slide guide 66 (cf. FIG. 3) has a substantially circular disk-shaped base plate 75, the outer diameter of which is approximately the same as the inner diameter of the tube section 60 32a, 61? corresponds. Opposite to each other spaced apart circular plate segments 76 are arranged on the base plate 75, which have an outer diameter which corresponds to the outer diameter of the tube section 61 or the inner diameter of the cylinder tube section 32a. The circular disk sections 76 are thicker than the base plate 75 and have opposite, parallel, flat guide surfaces 77 which, together with the base plate 75, for the displaceable mounting of a slide 78, which de- waisted is described. The base plate 75 thus forms, together with the guide surfaces 77, a guide groove for the slide 78 which is U-shaped in cross section.

The slide 78 is a first coupling member and has an essentially disk-shaped three-dimensional shape and has straight opposite guide edges 79 which cooperate with the guide surfaces 77, so that the slide 78 is guided between the circular disk sections 76. The front edges of the slider 78 are arcuate. The outside diameter of the slide 78 between the end edges corresponds to the inside diameter of the cylinder tube section 32a. A u-shaped recess 80 extends from one of the guide edges 79 into the interior of the slide 78. The eccentric nipple 53 of the locking cylinder 4 engages in this u-shaped recess 80 when assembled. When assembled, the slide guide 66 with the circular disk sections 76 is seated on the end steps 65 of the pipe section 61. The slide guide 66 is together with the slide 78 with respect to. of the push button lower part 31 can be displaced in a double arrow direction or axial direction 81 (FIG. 10), the slide guide 66 being guided along the free side edges 69 of the stop tab 67.

The structure of the locking device 5 is described in detail below with reference to FIGS. 5 and 6.

The housing part 22 has an essentially L-shaped and cross-sectionally U-shaped three-dimensional shape with a housing bottom wall 91, a first L-shaped side wall 92 and a second L-shaped side wall 93 and an end wall 94. The second side wall 93 has the outer surface 27 in the region of the insertion opening 15, which together with the insertion opening 15 forms a passage with a circular cross section. The bottom wall 91 has a first long bottom wall section 91a in the region of the long leg 24 and a second short bottom wall section 91b in the region of the second short leg 25. The bottom wall sections 91a and 91b merge with one another with a bottom wall arc section 91c.

The first side wall 92 has a first long side wall section 92a in the region of the first long leg 24, a second short side wall section 92b in the region of the second short leg 25 and a side wall arch section 92c in between. The second side wall 93 has a first long side wall portion 93a in the area of the first long leg 24, a second short side wall portion 93b in the area of the second short leg 25 and a side wall arc portion 93c therebetween, the first long side wall portion 93a, the side wall arc portion 93c together in assembly form a surface aligned with the surface of the handle body 2.

The end wall 94 lies flush against the free end 18 of the blind hole recess 17 in the assembly. The front side wall 94 has two recesses 95 in the region of the side wall 92, through which the electrical lines 26 can be led out of the interior of the housing.

In the area of the first leg 24 there is a motorized axial drive 100, e.g. a lifting magnet with a magnetic body 101 and a piston rod 102 which is guided in a central bore and protrudes from the bore. The piston rod

102 is outside the magnetic body 101 via a cross pin

103 connected to a rocker arm or cam arm 104, which sits in front of the head on the piston rod. The rocker arm 104 has, in the region of its free end 105, an elongated hole recess 106 extending perpendicular to the longitudinal extent, in which a pin 107 extending transversely thereto is mounted, via which the rocker arm 105 is connected to a lever arm 111 of a two-armed bell crank 108. The deflection lever 108 has a bore 109 with which it is pivotably mounted on a cylinder 110a with an axis 110 which extends vertically away from the bottom wall 91 in the region of the bottom wall arc section 91c. The deflection lever 109 has a second lever arm 112 lying opposite the first lever arm 111. The axial drive 100, the rocker arm 104 and the first lever arm 111 of the deflection lever 108 are arranged in the region of the first leg 24 of the housing 21. The second lever arm 112 of the deflection lever 108 protrudes from the axis 110 into the second leg 25 of the housing 21. The deflection lever 108 has an actuating section 113 in the region of the free end of the second lever arm 112. The actuating section 113 tapers towards the free end and has a sliding surface 114 which, when assembled, faces the insertion opening 15. By axially extending the axial drive 100 in a direction 120, the bell crank is pivoted about the axis 110 in a direction 121 via the rocker arm 104.

The second bottom wall section 91b has a right-angled, L-shaped angular groove 122 with a first short groove leg 122a and a second long groove leg 122b. The first groove limb 122a runs parallel to the actuation direction 120 of the axial drive 100. The second groove limb 122b runs parallel to the actuation longitudinal axis 14. At the free end of the first groove limb 122a, it ends in the transition region between the bottom wall section 92c and the second side wall section 92b of the side wall 92. Laterally aligned with A stop bracket 123 for the slide 28, which will be described further below, is formed on the groove leg 122a on the inside of the second side wall section 92b. Opposite the second side wall section 92b, the side wall section 93b has a recess below the outer surface 27, from which the slide 28 protrudes.

The slide 28 is a further coupling member and has a slide plate 130 and a stop tab or stop web 131 which extends perpendicularly from the slide plate 130 in the region of one end of the slide plate 130. The stop tab 131 has a free edge 131a and has a width which is less than or equal to the clear width of the window 40. In the region of the other end of the slide plate 130, a projection 132 is formed on each side of the slide plate 130. The projections 132 run in the assembly in the angular groove 122, ie they are in engagement with the angular groove legs 122a and 122b. Opposite to the angular groove 122 in the bottom wall 91, an angular groove 122 'with a first angular groove leg 122a ¹ and a second angular groove leg 122b' is also formed in the cover 23. The angular grooves 122 and 122 'serve to guide the slide 130. In an operating position, the slide plate 130 rests on the support bracket 123. The slide plate 130 also has an essentially square push-through window 133 which extends through the free end 113 of the deflection lever 108. The stop lobe 131 of the slider 28 has a three-dimensional shape in the form of a cylinder tube wall, the inside diameter of which approximately corresponds to the outside diameter of the tube section 61 and the outside diameter of which roughly corresponds to the outside diameter of the cylinder tube section 32a. In the extension of the slide plate 130, a slide projection 134 extends beyond the stop tab 131 and has a circular arc-shaped groove at its free end, the diameter of the groove approximately corresponding to the inside diameter of the tube section 61. The housing 21, in which the axial drive 100, the rocker arm 104, the deflection lever 108 and the slide 28 are mounted, thus form the locking drive device 5, which can be inserted into the handle body 2 in a module or cassette-like manner.

In the following, the assembly of the actuating device 1 is described in more detail with reference to FIG. 7 in addition to what has been described so far.

When assembled, the compression spring 6 is supported at one end on a bottom wall of the receiving device 16 and at the other end it bears against the annular end face 35 of the cylinder tube section 32a of the push-button upper part 30. The push button lower part 31 is connected to the push button upper part 30 so that it can be moved axially in the direction 81 by means of the clip connection described above. The push-button upper part 30 is supported by means of the sealing ring 32 in the insertion opening 15 in cooperation with the outer surface 27 in the handle body 2. The push button lower part 31 passes through a bore in the bottom wall of the receiving device 16 and is connected to the actuating element 8. The free end 113 of the deflection lever 108 extends through the slide plate 130 of the slide 28, the slide 28 being guided in the grooves 122, 122 'in the housing 21. The windows 40 of the push button 3 are arranged such that the window 40, in which the stop tab 67 of the lower part 31 of the push button is arranged, is opposite the slide 28. The slide 78, which can be actuated manually via the locking cylinder 4, engages with the eccentric nipple 53 of the locking cylinder 4 and, by means of the eccentric nipple 53, is in a direction perpendicular to the axis 14, e.g. with a key by turning the lock cylinder 4 back and forth.

In the following, a first operating position ("central locking or locking device 5 open") is based on the fi guren 7 and 8 described. In the position according to FIG. 7, the push button 3 is not actuated and in the position according to FIG. 8 it is actuated, that is to say pressed in.

According to FIG. 7, the axial drive 100, ie the lifting magnet, is energized so that the push rod 102 is retracted. In this position, the lever arm 112 of the deflection lever 108 is positioned such that the sliding surface 114 is aligned parallel to the longitudinal axis 14 of the actuation. The slide 28 sits with its guide projections 132 in the corner region of the angular groove 122, so that the stop flap 131 of the slide 28 comes into contact with the stop flap 61 of the push-button lower part 31 and the free end edge 131a rests on the step 71. Furthermore, the upper edge 43 of the window 40 facing the slide 28 rests in the push button upper part 30 on the slide plate 130. In addition, the projection 134 lies on the free end edge 68 of the stop tab 67. Thus, the push button upper part 30 is positively coupled to the push button lower part 31 via the slider 28, which in turn is positively connected to the actuating element 8, so that by pressing the push part 33 according to FIG. 8, the push button upper part 30 together with the slider 28 and the push button lower part 31 and the actuating element 8 is displaceable by the length 1 (see FIG. 8). In this position, the slide 28 with its projections 132 is located at the free end of the second groove leg 122b or 122b ¹ . The compression spring 6 is compressed. By releasing the pressure part 33, the compression spring 6 expands and brings the push button 3 back into the starting position according to FIG. 7. By moving the actuating element 8 by the length 1, a lock mechanism is actuated (not shown).

In the second operating position according to FIGS. 9 and 10 ("central locking closed"), the axial drive 100 or the solenoid 101 is de-energized, so that the push rod 102 is extended. The actuating lever arm 112 of the deflection lever 108 is pivoted towards the console 123 and lies against the console 123. When pivoting, he took the slider 28 with him, which abuts in the retracted position in the free end of the groove leg 122a, the slider plate 130 resting on the bracket 123. In this position, the stop tab 131 of the slide 28 is arranged at a distance from the stop tab 67 of the lower push-button part 31, so that the upper edge 43 of the window 40 facing the slide 28 is exposed. Otherwise, all other components of the actuating device 1 are in the position according to FIG. 7. When the push button 3 is pressed by pressing in the direction of the arrow according to FIG. 10, there is no positive or non-positive connection between the push button upper part 30 and the push button lower part 31 in this operating position, so that the push button upper part 30 is displaceable in the axial direction 14 relative to the push button lower part 31. The push button upper part 30 and the push button lower part 31 are mechanically decoupled. By pressing according to FIG. 10, only the push button upper part 30 is thus axially displaced, so that the compression spring 6 is compressed. The lower part of the pushbutton "remains" in its starting position according to FIG. 9, so that actuation of a lock mechanism (not shown) by the actuating element 8 is omitted, thus extending the actuating element 8 by the length 1 is prevented. In this so-called idle stroke, the catch projections 64 are lifted off the lower edges 41. The locking projections 64 and the support projection 70 are guided between the side edges 42 of the windows 40 in the cylinder tube section 32a and are displaced relative to the push-button upper part 30. By releasing the push button 3, the push button upper part is pushed back into the starting position according to FIG. 9 by the pressure spring 6. In this position, it is therefore not possible to open a motor vehicle door or the motor vehicle flap (not shown), since the actuating element 8 is mechanically decoupled from the push-button upper part 3. In the operating position of the locking device 5 according to FIGS. 9 and 10, ie the operating position "central locking closed", the actuating device 3, 30, 31 can be mechanically coupled manually in a conventional manner by inserting the key into the locking cylinder 4 and rotating the same. After inserting the key into the lock cylinder 4, the rotating body 51 is rotatable. By rotating the rotating body 51 about the axis 14, the eccentric nipple 53 is moved from the position according to FIG. 9 (to the right of the longitudinal axis 14) into an open position (to the left of the longitudinal axis 14 (not shown)). As a result, the slide 78 is shifted from its position shown in FIG. 9 to the left, so that it comes to rest over the free edge 68 of the stop tab 67 of the push-button lower part 31. He can also displace the slide 28 when it is in the position shown in FIG. 7, because the locking device 5 is preferably set up so that it can be displaced. In this position, actuation of the actuating element 8 can be achieved by pressing the pushbutton 3, since the pushbutton upper part 30 is mechanically coupled to the actuating element 8 via the locking cylinder 4, the slide 78, the stop tab 67 of the lower part 31 of the pushbutton. This means that the lock can also be operated purely manually, for example in the event of a power failure.

According to the invention, instead of the axial drive 100, a rotary drive, in particular an electric motor 200, is provided with a drive worm 201, preferably guided in a central bore and protruding therefrom in the direction of the push button 3, with a drive worm thread 203 (FIGS. 11-13). The drive screw 201 is expediently arranged with its screw longitudinal or rotational axis 202 perpendicular to the actuating longitudinal axis 14 and parallel to a longitudinal direction 219 of the handle body 2. In addition, the deflecting lever 108 according to the invention does not have a first lever arm 111, but opposite the lever arm 112 has a gear ring segment 204 running in an arc, the helical toothing 205 of which is designed to correspond to the drive worm thread 203. The ring gear segment 204 is dimensioned and arranged in such a way that in the assembled state the helical toothing 205 is in engagement with the drive worm thread 203. For this purpose, the gear rim segment 204 expediently runs in an arcuate manner such that a gear rim center axis 206 is parallel to the axis 110, or is preferably coaxial with it.

In addition, according to the embodiment shown in FIGS. 11-13, the lower part 31 of the push button does not have any locking projections 64, but the stop tab 67, in particular in the form of a cylindrical tube segment, is offset radially outward in relation to the tube section 61 in such a way that the stop tab 67 is arranged over an annular web 207 merges into the pipe section 61. The ring web 207 is preferably formed all the way round and has a circumferential outer ring web edge 209. The outer diameter of the stop tab 67 or the outer ring web edge 209 corresponds to the inner diameter of the cylinder tube section 32a of the push button upper part 30, so that the push button lower part 31 is slidably guided in the cylinder tube section 32a of the push button upper part 30 in the direction 81 of the actuation longitudinal axis 14.

In order to secure the push button upper part 30 against slipping out in the axial direction 81 upwards, two locking pins 211 are provided. The locking pins 211 are each mounted in two radially opposite bores 218, which are provided in the lower region of the cylinder tube section 32a, in the vicinity of the ring end face (35). The bores 218 are arranged such that the two securing pins 211 are parallel to one another and by the amount of the outer diameter of the tube section 61 of the lower part 31 of the push button are spaced from one another, so that the securing pins 211 bear against an outer tube section wall 61a and can slide along this. In the non-depressed state (FIG. 12), the push button upper part 30 is pressed upwards by the compression spring 6 in the direction of the longitudinal actuation axis 14, so that the securing pins 211 rest against the ring web 207 serving as a stop and the push button upper part 30 is secured against slipping out upwards . When the push button upper part 30 is actuated, the securing pins 211 slide down along the outer tube section wall 61a.

Furthermore, the slide guide 66 is integrated in the push button upper part 30, that is to say it is formed in one piece with the push button upper part 30. The slide guide 66 adjoins the tube section 32a essentially inwards.

In addition, the push button upper part 30 only has one window 40 for receiving the slide 28.

The actuation device according to the invention is actuated, as already described in detail above, by mechanical coupling or uncoupling of the push-button upper part 30 and the push-button lower part 31 by moving the slide 28 by means of the deflection lever 108, the slide 28 being in the coupled position shown in FIGS. 12 and 13 the free end edge 68 of the stop tab 67 rests and is supported on this. By pressing the push part 33 of the push button 3, the push button lower part 31 and with this the actuating element 8 are actuated via the slide 28 and taken down in the axial direction (FIG. 13). In this position, the slide 28 with its projections 132 is located at the free end of the second groove leg 122b or 122b ¹ . The compression spring 6 is compressed. By releasing the pressure part 33, the compression spring 6 expands and brings the push button 3 back into the starting position according to FIG. 12. By extending the actuating element 8 by the length 1 As already explained, a lock mechanism is actuated (not shown).

In order to bring the push-button upper part 30 and the push-button lower part 31 into the mechanically decoupled position (not shown) by operation via central locking, the electric motor 200 is switched on and by this the drive screw 201 is set in rotation. The rotational movement of the drive worm 201 is then transmitted via the drive worm thread 203 to the helical toothing 205 of the ring gear segment 204 and the bell crank 108 is pivoted about the axis 110, so that the lever arm 112 is moved away from the push button 3 and the slide 28, as already explained above , takes along so that the push button upper part 30 and the push button lower part 31 are mechanically decoupled. In this position, the push button upper part 30 can be freely moved downwards without taking the push button lower part 31 with it, the cylinder tube section 32a sliding along the outer edge of the ring land 209 and the stop flap 67, so that the push button upper part 30 and the push button lower part 31 are pushed into one another and that Actuator 8 is not actuated.

The return lever 108 is pivoted back into the coupled position shown in FIGS. 12 and 13 by driving the worm gear 201 again by the electric motor 200 in the opposite direction of rotation.

Coupling or uncoupling with the aid of a key also takes place, as already described in detail above, by actuating the slide 78 via the eccentric nipple 53.

The actuating device according to the invention requires very little installation space due to the direct actuation of the deflection lever 108 by the worm gear 201 and is very easy and simple to assemble due to the small number of individual components. Of course, it is also within the scope of the invention to carry out push button upper part 30 and push button lower part 31 in accordance with the previously described embodiments with locking projections 64 and two windows 40 etc. or separate slide guide 66.

According to a further embodiment of the invention, the actuating device for actuating the lock by means of central locking also has a locking device 5 with a rotary drive, in particular an electric motor 220, which has a drive screw 221, preferably guided in a central bore and protruding therefrom, with a drive screw thread 222 (Fig. 14-23). The worm gear 221 is also expediently arranged with its worm longitudinal or rotational axis 223 perpendicular to the actuating longitudinal axis 14, but angled with respect to the longitudinal direction 219 of the handle body 2.

Furthermore, the locking device according to FIGS. 14-23 has a rotatably mounted gearwheel 224 with a helical toothing 225 corresponding to the drive worm thread 222, the gearwheel rotation or center axis 226 of which is parallel to the actuation longitudinal axis 14 and in the longitudinal direction 219 of the handle body 2 is flush therewith is arranged. In the downward direction of the gearwheel axis of rotation 226, a cam 227 adjoins the gearwheel 224 with its cam cylinder 228 and its cam elevation 229. The cam 227 is in fixed connection with the gear 224 and is preferably made in one piece with it. The cam cylinder axis 230 is arranged coaxially with the gear rotation axis 226. On the cam elevation 229, which is eccentric with respect to the cam cylinder axis 230, there is provided a preferably cylindrical driver or guide pin 231 which extends upward in the direction of the gear 224 parallel to the gear rotation axis 226. According to the invention, the actuating device also has a movable coupling member, in particular a coupling lever 232. The coupling lever 232 is preferably cuboid and essentially elongated along a longitudinal direction 233 of the lever, with one, in particular also cuboid, actuating or guide piece 234 being arranged or formed on one end. In addition, a continuous bearing bore 235 is provided approximately centrally with respect to the longitudinal extension of the coupling lever 232, the bearing bore axis 236 of which runs perpendicular to the longitudinal direction of the lever 233 and coaxially to the longitudinal axis 14 of the actuation. The bearing bore 235 serves for rotatably mounting the coupling lever 232 on the push button upper part 30 about the vertical actuation longitudinal axis 14, which will be discussed in more detail below.

The guide piece 234 is arranged offset upward in the direction of the bearing bore axis 236 with respect to the coupling lever 232 and has a pin guide slot 237 which extends in the direction of the lever longitudinal direction 233 and is open towards a guide piece end 234a. The width of the pin guide slot 237 preferably corresponds to the diameter of the guide pin 231, which is movably guided in the pin guide slot 237 parallel to the direction of the lever longitudinal direction 233, which will be discussed in more detail later.

According to the embodiment shown in FIGS. 14-23, the push button upper part 30 has no window cutouts 40, but a lever guide slot 238 which extends in the cylinder tube section 32a somewhat below the pressure part 33 in the circumferential direction and has two slot side edges 239a which extend parallel to the actuation longitudinal axis 14 and radially to the latter. b, a, preferably flat, slotted lower edge 240, which is arranged perpendicular to the longitudinal axis of actuation 14, and a, preferably likewise flat, slotted upper edge 241 parallel to the lower slotted edge 240. Here the slot lower edge 240 and the slot upper edge 241 are expediently spaced apart from one another by the amount of the thickness or height of the coupling lever 232, that is to say the distance from the upper side 257 of the lever and the lower side 258 of the lever. In the lever guide slot 238, the coupling lever 232 is arranged with its bearing bore 235 coaxially to the longitudinal axis 14 of the actuation and is axially secured, that is to say axially immovable, but rotatable about the longitudinal axis 14 of the actuation.

In addition, two radially opposite axial securing slots 242, in which an axial securing pin 243 is guided, are provided in the push button upper part 30 and extend in the direction of the actuation longitudinal axis 14. The axial securing pin 243 is also positively mounted in a bore 244 provided in the push button lower part 31, which is oriented perpendicular to the longitudinal actuation axis 14, so that the push button upper part 30 with the push button lower part 31 by a limited amount, in particular essentially according to the length the axial securing slots 242, is axially displaceably connected and the push button upper part 30 is secured against slipping out upwards.

According to the embodiment shown in FIGS. 14-23, the push-button lower part 31 has only a short tube section 61, to which the stop tab 67 shaped as a cylinder wall segment adjoins as an upward extension. The stop tab 67 is not arranged symmetrically to the longitudinal direction 219 in a plan view in the direction of the longitudinal axis 14 of the actuation, but the push button lower part 31 is arranged rotated about the longitudinal axis 14 such that the stop tab 67 is arranged offset to the longitudinal direction 219. In particular, the stop tab 67 is in a bottom view in the direction of the actuation longitudinal axis 14 of the actuating device. tion pivoted counter-clockwise compared to the symmetrical arrangement.

A cylindrical section 245 with the same outer diameter as the pipe section 61 connects to the short pipe section 61 in the axial direction and the stamp section 60 connects to it. In the cylinder section 245, the bore 244 is provided perpendicular to the longitudinal axis 14 of the actuation.

According to a preferred embodiment of the invention (FIG. 23), the push-button lower part 31 has two stop tabs 67 arranged radially opposite one another.

Furthermore, the lower part 31 of the snap fastener likewise has no locking projections 64.

Instead of the eccentric nipple 53, the rotating body 51 of the locking cylinder 4 has a lever bearing cylinder 246 which is arranged centrally to the longitudinal axis 14 of the actuation and which projects a little downward in the axial direction from a rotating body base 247, in particular at least by the amount of the thickness of the coupling lever 232. The diameter of the lever bearing cylinder 246 preferably corresponds to the diameter of the bearing bore 235, so that the coupling lever 232, which is mounted with its bearing bore 235 on the lever bearing cylinder 246, is rotatably arranged about the actuation longitudinal axis 14. The coupling lever 232 expediently bears with the lever top 257 on the rotating body base 247.

Furthermore, the rotating body 51 has two rotating or actuating segments 248, 249 which are located radially opposite one another and also adjoin the rotating body base 247 in the axial direction. The rotating segments 248, 249 each have a segment outer edge 250 which extends in the circumferential direction with respect to the actuating longitudinal axis 14 and whose diameter expediently corresponds to the outer diameter of the rotating body 51. speaks, and two flat segment side edges 252a, 252b, 253a, 253b. The segment side edges 252a, 252b, 253a, 253b are dimensioned such that the segment side edges 252a, 253b or 252b, 253a, which are not opposite one another, are parallel to one another and spaced apart by the amount of the width of the coupling lever 232, that is to say the distance from lever side edges 254,255. so that the two rotating segments 248, 249 are preferably substantially triangular in a plan view (FIGS. 18, 22) along the longitudinal actuation axis 14. Expediently, the two segment side edges 252a, 252b and 253a, 253b of the respective stop segment 248, 249 merge into one another in a rounded corner edge 256.

The actuation device according to the invention in accordance with the embodiment shown in FIGS. 14-23 is likewise actuated by coupling or uncoupling the push-button upper part 30 and the push-button lower part 31 the actuating longitudinal axis 14 pivots that the coupling lever 232 is arranged in the direction of the actuating longitudinal axis 14 in alignment with the stop tab (s) 67 and rests with the lever underside 258 on the free end edge (s) 68 of the stop tab (s) 67 , the longitudinal direction of the lever 233 expediently including an acute angle α with the longitudinal direction 219 of the handle body 2. The slit side edge 239b of the lever guide slot 238, on which the lever side edge 254 of the coupling lever 232 bears in this position, expediently serves as a stop.

The coupling lever 232 is pivoted here by switching on the electric motor 220, by means of which the drive worm 221 is set in rotation. The rotational movement of the drive worm 221 is then transmitted via the worm thread 222 to the helical toothing 225 of the gear 224, which rotates clockwise in a bottom view in the direction of the actuation longitudinal axis 14 in this case. The coupling lever is then rotated counter-clockwise about the longitudinal actuation axis 14 via the cam 227, which is fixedly connected to the gear wheel 224, and the eccentrically arranged guide pin 231 of the cam 227, expediently until the lever side edge 255 abuts the slot side edge 239b.

Thus, in this first operating position, the push-button upper part 30 is mechanically positively coupled to the push-button lower part 31 via the coupling lever 232, which in turn is positively connected to the actuating element 8.

In the case of two stop tabs 67 (FIG. 23) provided, the two stop tabs 67 lie opposite one another in the direction of the longitudinal direction 233 of the lever.

So that the push button upper part 30 can also be actuated, the cam 227 is also rotated somewhat further clockwise relative to the coupling lever 232, so that the guide pin 231 is no longer guided in the pin guide slot 237 which is open towards the rear, and the coupling lever 232 is removed from the cam 227 is decoupled or freely axially movable (not shown). The extent to which the cam 227 is rotated by means of the electric motor 220, that is to say how long the electric motor 220 is actuated, is controlled, for example, by a Hall sensor 260 or the like revolution meter which is connected to a control module (not shown) of the actuating device and the position of the coupling lever 232 measures.

By pressing the push part 33, the push button upper part 30 can now be displaced by the length 1 together with the coupling lever 232 and the push button lower part 31 and the actuating element 8 (cf. FIG. 19). The compression spring 6 is rimed. By releasing the pressure part 33, the compression spring 6 expands and brings the push button 3 back into the starting position according to FIG. 17.

In order to bring the push-button upper part 30 and the push-button lower part 31 into the mechanically decoupled position by operation via central locking (Fig. 19-23), the electric motor 220 is switched on and by this the drive taste 221 rotates in the opposite direction as when the coupling lever 232 was brought in the coupled position is offset. The rotational movement of the drive worm 221 is then in turn transmitted via the worm thread 222 to the helical toothing 225 of the gear 224 and thus to the cam 227 fixedly connected to the gear 224 and the coupling lever 232 via the eccentrically arranged guide pin 231 of the cam 227 about the actuation longitudinal axis 14, this time pivoted clockwise. The coupling lever 232 is pivoted until it is no longer aligned in the direction of the actuation longitudinal axis 14 with the stop tab 67 or with the underside of the lever 258 on the free end edge (s) 68 of the stop tab (s) ( s) 67 rests. This time, the slot side edge 239a is expediently used as a stop, on which coupling lever 232 strikes and rests with its lever side edge 255.

Expediently, the longitudinal direction of the lever 233 then includes an acute angle β with the longitudinal direction 219 of the handle body 2, which corresponds in terms of magnitude to the angle α and has the opposite sign in relation to the longitudinal direction 219 of the handle body 2, that is to say the coupling lever 232 is mirror-inverted to the longitudinal direction 219 in comparison to coupled position (Fig.16-19) is arranged. The cam 227 is in turn a little further than the coupling lever 232, this time viewed counterclockwise in a bottom view, rotated (not shown), so that the guide pin 231 is no longer in the pin guide open towards the rear. tion slot 237 is guided, and the coupling lever 232 is uncoupled from the cam 227 or is freely movable axially therewith. The control of the electric motor 220 is expediently carried out again via the Hall sensor 260.

By pressing the pressure part 33, in the mechanically decoupled position, only the push button upper part 30 together with the coupling lever 232 is moved downward in the direction of the actuation longitudinal axis 14, since the coupling lever 232 is guided past the stop flap (s) 67. The lower part 31 of the push button and the actuating element 8 are not actuated (FIG. 23).

When the actuating device is actuated by central locking, the locking cylinder 4 is initially in a central position (FIGS. 18, 22) in which it is held in a manner known per se by a torsion spring or center-zero spring 259. In this middle position, the two rotating segments 248, 249 are expediently arranged symmetrically to the longitudinal direction 219 in such a way that in the coupled position of the coupling lever 232 the segment side edges 252b, 253a are parallel to the lever side edges 254, 255 and in the decoupled position of the coupling lever 232 the segment side edges 252a, 253b the lever side edges 254, 255, so that the coupling lever 232 can be pivoted freely by central locking.

The manual actuation of the actuating device by means of a key also takes place by rotating the rotating body 51 of the locking cylinder 4, which can be rotated about the actuating longitudinal axis 14 after the key has been inserted into the locking cylinder 4. By rotating the rotating body 51 clockwise, the coupling lever 232, for example from the coupled position (FIG. 18), in which the lever side edge 255 bears against the segment side edge 253a and the lever side edge 254 bears against the segment side edge 252b, of the rotating segments 248, 249 positively carried and rotated until the coupling lever 232 strikes with its lever side edge 255 on the slot side edge 239a, so that the coupling lever 232 is in the mechanically decoupled position.

After releasing the key, the center-zero spring 259 rotates the locking cylinder 4 back into the central position.

The coupling lever 232 is rotated from the decoupled (FIG. 22) to the coupled position (FIG. 18) analogously by turning the locking cylinder counterclockwise, the lever side edge 255 resting on the segment side edge 253b and the lever side edge 254 resting on the segment side edge 252a, so that the coupling lever 232 is positively entrained by the rotating segments 248, 249 and rotated until the coupling lever 232 strikes with its lever side edge 255 on the slot side edge 239 and bears against it.

After releasing the key, the center-zero spring 259 in turn rotates the locking cylinder 4 back into the central position.

It is advantageous in this embodiment of the invention that no additional component is required for the manual actuation of the actuating device, which considerably simplifies the entire construction. The coupling lever can be operated both manually and via central locking. In addition, due to the few components, this embodiment of the invention also has a very small installation space and is therefore particularly light and simple to install. Of course, it is also within the scope of the invention to also design the locking device in a modular manner.

In summary, the actuating device according to the invention is particularly advantageous in that it has a particularly compact construction and enables both manual closing and opening and remote-controlled opening and closing. light. It is particularly advantageous if the electrically controllable locking device 5 is designed in a module or cassette-like manner and is inserted into the handle body and thus a variation of the actuating device with and without a remotely controllable unlocking functionality can be implemented in a simple manner. By omitting the locking device 5 and simply closing the elongated hole recess in the handle body 2 by means of a cover or a cover (not shown), the actuating device according to the invention can optionally be designed with and without a remote trigger functionality. A complex assembly, for example in a door body of a motor vehicle, as is usually done, is not required.
