    The present invention relates to a drive device having the features of the preamble of claim 1. Furthermore, the invention relates to a piece of furniture with such a drive device for a movable furniture part.
    In the furniture fitting industry, there have been many mechanical aids for many years to make it easier for a user to move a movable furniture part (for example, a drawer, a furniture door, or a furniture door) from a closed position in the opening direction. Above all, so-called touch-latch mechanisms or TIP-ON devices are used, which usually have heart-shaped locking guide tracks for a locking pin. By overriding the movable furniture part in a lying behind the closed position overpressure an unlocking and subsequent ejections is triggered.
    One problem that often occurs is the generation of noise. Especially if due to the relatively heavy drawers to move the ejection force storage must hold a relatively large ejection force, it is especially before and at the locking of the locking pin in the detent recess of the locking guide track to strong noise due to the striking of the locking pin on the locking guide track.
    In order to at least partially solve this, WO 2014/165874 A1 discloses a damped locking pin movement. In particular, the locking pin acted upon by the tensioned ejection force accumulator is braked and / or damped and moved in the latching movement area and deposited in the latching area. For this purpose, according to this document relatively many components are necessary, which act damping or speed-influencing on the locking pin. In addition, nevertheless, a noisy impact of the locking pin in the locking guide track can occur during the transition from the clamping section into the latching movement area.
    The object of the present invention is therefore to provide a comparison with the prior art improved or an alternative drive device.
    In particular, the disadvantages of the prior art should be eliminated or an alternative possibility for a quiet movement of the locking pin in the locking guide track to be created.
    This is achieved by a drive device having the features of claim 1. Accordingly, the invention provides that one of the locking guide track and the locking pin separate control device is provided and the movement of the locking pin in the locking guide track is at least partially controllable by the control device. Thus, it is possible that, as in the prior art, the speed of movement of the locking pin but the path of movement of the locking pin is noise reducing influenced. Above all, this movement path is no longer determined only by the formation of the locking guide track alone for the first time. Rather, in addition, a further, from the locking guide track largely independent control device is present. Thus, the movement sequence of the locking pin is additionally guided, at least in critical subregions.
    Preferred embodiments of the present invention are indicated in the dependent claims.
    It is preferably provided, for example, that the locking pin is formed on a carrier, wherein the movement of the carrier is controllable by the control device. This support may, for example, be pivotable about a pivot axis aligned at right angles to a longitudinal axis. For a compact design but is preferably provided that the carrier is rotatable about a parallel, preferably colinear, aligned with the longitudinal axis of the ejection device rotation axis.
    The control device itself can be designed electronically in principle. However, the control device preferably has at least two mechanically interacting components which influence the path of the locking pin.
    In a particularly preferred embodiment, it is therefore provided that the control device has a support arranged on the carrier, separate from the locking pin coupling pin and a coupling element preferably formed in a coupling element, wherein the coupling track, a preferably undercut, holding surface for holding the coupling pin and a beveled area Deflection of the coupling pin has in a guide region of the coupling track.
    These components alone may be sufficient to control the path of movement of the locking pin. Preferably, however, it is additionally provided that the control device has a control track, which is preferably formed in a housing cover of a housing, and has a control element which preferably rotates about the axis of rotation and which engages in the control track. These two additional components make it possible that by moving the control pin along an inclined deflection control track region of the control track, a rotational movement of the coupling element about the rotation axis is triggered, so that the coupling pin passes from the holding surface in the oblique region of the coupling path in the coupling element.
    As such, the controller may control the path of travel of the locking pin throughout the locking guide track. Preferably, however, it is provided that the locking guide track has a substantially longitudinally oriented clamping portion, a cam portion, a Vorverriegelungsabschnitt and a latching portion, wherein the movement path of the locking pin is controlled only in these portions of the locking guide path of the control device. This is done primarily by the fact that on the locking pin when leaving the clamping portion through the simultaneously located in the oblique portion of the coupling track and deflected by this oblique portion coupling pivot a rotation of the carrier about the rotation axis is triggered and by this rotational movement of the support and the movement of the locking pin along the Curve section is controlled in the Vorverriegelungsabschnitt. As a result, the Vorverriegelungsstellung is quietly and safely achieved.
    In a further consequence, it can also be provided that a rotational movement of the coupling element about the rotational axis can be triggered by moving the control pin along an inclined latching control track region of the control track, wherein the coupling pin bears against the guide region of the coupling track and participates in this rotational movement. By the motion transmission of the rotational movement of the coupling element on the coupling pin and the carrier is movable relative to the locking guide track, whereby the likewise arranged on the carrier locking pin controlled by Vorverriegelungsabschnitt on the latching and thus quietly gets into the locking recess of the locking guide track.
    In principle, no pre-locking must be present. Thus, the movement path of the locking pin could also be controlled directly from the clamping section into the detent recess via the control device.
    When the ejection device has an ejection force accumulator and an ejection slide force-loaded by the ejection force accumulator, the ejection slide forms the carrier on which the locking pin is arranged. For a compact design with as many functions as possible, the drive device has a housing, wherein the ejection device and a retraction device for retracting the movable furniture part from an open position to the closed position in this common housing are arranged.
    Protection is also desired for a piece of furniture with a furniture body, a movable furniture part and a drive device according to the invention.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:

    In Fig. 1, a furniture 50 is shown with a furniture body 51 and three superimposed movable furniture parts 2 in the form of drawers in a perspective view.
    Fig. 2 shows in a view obliquely from below the movable furniture part 2, wherein on both sides of the pullout guides 52 are shown. On each pull-out guide 52, in particular on each drawer rail 54 of the pull-out guide 52, a drive device 1 for a movable furniture part 2 is arranged. If a synchronization device 76 is present for the ejection devices 3 and 3 'of both drive devices 1, then both drive devices 1, which are preferably mirror-symmetrical to one another, together form a common drive device 1'. On the underside of the carcass rail 53 of both extension guides 52, a pin-shaped carrier 49 is attached via a holding plate, which interacts with the respective drive device 1. In this case, each drive device 1 is associated with the movable furniture part 2 (in particular the drawer rail 54), while the driver 49 is corpusfest. Thus, the drive device 1 abuts, so to speak on the fixed carrier 49. The described drive device 1 can also be used in the reverse manner, namely that the drive device 1 on the furniture body 51 and on the
    Carcass rail 53 is mounted and on a driver 49 - which is then associated with the movable furniture part 2 - acts. As a result, the driver - together with the movable furniture part 2 connected to the driver 49 - is ejected in the opening direction OR from the drive device 1.
    FIG. 3 shows in a perspective view the pull-out guide 52 comprising the carcass rail 53 and the drawer rail 54, together with the drive device 1 mounted on the drawer rail 54.
    FIG. 4 a shows a section through the drive device 1 and the pull-out guide 52 in the region of the synchronization rod holder 35. It can be seen herein that the pull-out guide 52 in addition to the carcass rail 53 and the drawer rail 54 also has a center rail 55 for a full extension. It is essential that both the ejection device 3 and the retraction device 4 are installed in a single housing, said housing having the housing cover 6 and the housing base plate 7 (The remaining reference numerals will be explained in more detail in later figures.). In principle, the housing can also be formed in one piece. Through the housing and the individual components must not be completely enclosed. Thus, the housing may well be formed only in the form of a kind of base plate on which all components are held. Preferably, the housing is in two parts and houses the individual components substantially completely. By a housing in which both the ejection device 3 and the retraction device 4 is arranged, a simpler and faster assembly of the drive device is possible.
    In contrast, a prior art is shown in Fig. 5a, as it is currently produced and sold by the applicant. It is noticeable at a glance that the two essential components of the drive device - namely the ejection device 3 and also the retraction device 4 - are formed and arranged separately from each other. D. h., The retractor 4 is mounted on a separate housing on the drawer rail 54, while the ejector 3 is also mounted on a separate housing on the retractor 4 (or on the underside of the movable furniture part 2, not shown). Both for the
    Ejector 3 as well as the retractor 4 each have a separate driver (not shown here) may be present.
    FIGS. 4b and 5b respectively correspond to the aforementioned FIGS. 4a and 5a, both of which show a front view of the respective drive device.
    With reference to FIGS. 6 and 7, the essential components of the drive device 1 will be described below. This drive device 1 has the housing cover 6 and the housing base plate 7 as the two housing elements. In principle, of course, more components could form the housing, but it is provided for a simple and inexpensive production as possible that only exactly two housing parts are available. About the housing base plate 7, the drive device 1 is mounted on the drawer rail 54.
    The two main components of the ejection device 3 (also called TIP-ON mechanism or touch-latch mechanism) are the ejection force memory 13 and the ejection slide 10, which along a longitudinal axis L are movable. This ejection energy storage 13 is formed in this case as a compression spring. In principle, this ejection energy accumulator 13 and also the ejection slide 10 could be held directly on the housing or on a housing part. In this case, a separate ejection housing is additionally provided, which is formed in the form of an inner ejection housing 11 and an outer ejection housing 12. In these ejection housing parts, the other two components (ejection energy storage 13 and ejection slide 10) are at least partially performed. In order to maintain the positioning of the ejection force accumulator 13 as accurately as possible, the guide pin 29 is provided. At this guide pin 29, the separating element 30 is also guided via a groove (in the guide pin 29) and a projection (on the separating element 30). This shim-disk-shaped separating element 30 serves to ensure that when the ejection slide 10 is rotated about the axis of rotation X aligned parallel to the longitudinal axis L and due to the torsion of the ejection force accumulator 13, there is no direct torque transmission between the ejection force accumulator 13 and the ejection element 10. At the power storage end facing the ejection slide 10, a locking pin 36 is arranged. This locking pin 36 forms together with a formed in the ejection housing 11,12 heart curved
    Locking guide track 41 and one in one piece with the
    Synchronization coupling piece 31 formed locking member 58 (see Fig. 9), a locking device 56 for the ejector 3. For the basic function, it would be sufficient if in this discharge housing 11,12 the locking guide track 41 is formed stationary. For a simple synchronization with the second drive device 1 arranged on the other side of the movable furniture part 2, a synchronization coupling piece 31 is provided. This synchronization coupling piece 31 is movable in the longitudinal direction L relative to the ejection housing 11, 12. This synchronizing coupling 31 is acted upon by the synchronizing force accumulator 32 (in this case a compression spring). The synchronization coupling piece 31 can be connected with a synchronization counterpart 33 mounted on the synchronization guide 34 of the housing such that it can be moved, in particular rotatably mounted, in a manner that transmits movement. Specifically, a rack is formed on the synchronization coupling 31, which meshes with a formed on the synchronization counterpart 33 gear. At synchronization counterpart 33, a synchronization rod 77 is attachable. For a secure mounting a synchronization rod holder 35 is provided. For the operation of this entire synchronization device, reference may be made by way of example to WO 2015/051386 A1.
    Furthermore, the drive device 1 has a retraction device 4. The essential components of this retraction device 4 are the Einziehkraftspeicher 18, the Einziehschlitten 15, the Einziehriegel 14 and Einziehverriegelungsbahn 17. The Einziehkraftspeicher 18 is held on the one hand to the Einziehkraftspeicherbasis 19 of the housing base plate 7 and on the other hand Einziehschlitten 15. In principle, the Einziehschlitten 15 can be locked directly in an angled end portion of the Einziehverriegelungsbahn 17. In this case, it is provided, however, that the Einziehriegel 14 is pivotally mounted on the Einziehschlitten 15 via Einziehverbindungszapfen 16, whereby the entire Einziehschlitten 15 is locked in a retractable locking position via a Einziehriegel 14 attached Einziehverriegelungszapfen 23 in the angled end portion of Einziehverriegelungsbahn 17. The Einziehkraftspeicher 18 is as
    Tension spring formed, which moves the Einziehschlitten 15 when relaxing in accordance with the illustration in Fig. 6 to the right.
    This retraction can be done only by the force of Einziehakraftspeichers 18. However, in order to enable a smooth retraction, the drive device 1 also has a damping device 5 for the retraction device 4. For this purpose, the damping device 5 has a cylinder 21 and a piston 20 guided in the cylinder 21. The damping cylinder 21 is held between the housing cover 6 and the housing base plate 7. The damping piston 20 is guided by the damping piston guide 22. This damper piston 20 acts in part during its movement path on the intermediate piece 24. This intermediate piece 24 is mounted on corresponding guide projections in the intermediate piece guide track 39 limited movable.
    In order to allow both the retraction device 4 and the ejection device 3 can be accommodated in a single housing 7, 6, the drive device further comprises a thrust element 8 and a coupling element 9. In the illustrations according to FIGS. 6 and 7, the coupling element 9 is shown in two parts. However, this is advantageous only for manufacturing reasons. Otherwise, this coupling element 9 may also be formed in one piece. The thrust element 8 in turn is displaceably mounted in the guideway 28 via corresponding projections. The catch fork 25 is guided in this guideway 28. In addition, the catch fork 25 is rotatably mounted on the catching fork bearing 27 on the thrust element 8. Furthermore, between the catch fork 25 and the thrust element 28 of the catch fork power storage 26 (in the form of a leg spring) is arranged, which guarantees a secure locking of the catch fork 25 in the angled end portion of the guideway 28. For a compact design it is provided that the housing 6, 7 of the drive device 1, the coupling element 9 and the ejection slide 10 (carrier) are at least partially sleeve-shaped or cylindrical. In particular, the ejection housing (11, 12) together with the locking guide track 41 formed therein, the coupling element 9 together with the coupling track 45 formed therein and the housing 6, 7 are cylindrically shaped, especially in the area of the control track 40 formed therein, wherein the locking guide track 41,
    Kuppelbahn 45 and the control track 40 are each formed on a curved about the rotation axis X, preferably inner, cylinder jacket surface.
    In Fig. 8, the housing cover 6 and the housing base plate 7 is shown in the unfolded state, so that the details formed therein are better visible. In both housing parts 6 and 7, the Einziehverriegelungsbahnen 17 for the Einziehriegel 14, the guideways 28 for the catch fork 25 and the thrust element 8 and the intermediate piece guide track 39 are each mirror-symmetrical. In contrast, in the housing base plate 7, the Einziehkraftspeicherbasis 19 and the steam piston guide 22 are formed. It is also apparent on the housing cover 6, the synchronization guide 34 and the opening 57 through which the synchronization coupling piece 31 protrudes from the housing.
    FIG. 9 shows in two different perspectives an insight into a discharge housing 11, 12 cut through in half. It can be seen that parts of the locking guide track 41 for the locking pin 36 are formed both in the inner ejection housing 11 and in the outer ejection housing 12.
    In addition, the catch recess R is partially formed by the inner discharge housing 11 and partially by a locking element 58. In the lower illustration of Fig. 9, the locking pin 36 is shown schematically when it is locked in the locking recess R.
    When the locking device 56 is unlocked by overpressing the movable furniture part 2 in the closing direction SR, the locking pin 36 is moved in the direction of the deflection slope 42 and deflected over this deflection slope 42, so that the locking pin passes into an ejection section of the locking guide track 41. After releasing the movable furniture part 2, the locking pin 36 contacts the locking element 58 on an end face (see FIG. 10), whereby the force of the ejection force memory 13 ejects the ejection slide 10 and, with it, the locking pin 36 attached thereto in the opening direction OR.
    Subsequently, the blocking element 58, which is formed integrally with the synchronizing coupling piece 31, is moved further in the opening direction OR until the position according to FIG. 11 is reached. In this position, the locking pin 36 is distracted again just by an inclined surface in the ejection section of the locking guide track 41 (see illustration of FIG. 11).
    FIG. 12 illustrates in various views that the ejection slide 10 has two opposite locking pins 36 at its end facing the ejection force accumulator. At the ejection force storage remote end, a hemispherical stop 43 is provided. This stop 43 serves to minimize the torque between the contacting parts (ejection slide 10 and coupling element 9). In addition, a recess is present at this end, in which a coupling pin 37, not shown here, can be attached.
    In FIGS. 13a to 13d, different, partially cut or partly transparent views of the sleeve-shaped coupling element 9 are shown. At this coupling element 9 of the control pin 38 is formed. In addition, the bayonet-like dome parts 44 are present at a head end. In the interior - ie on the cylinder jacket inner surface - this coupling element 9 are two identical, mutually offset by 180 °, coupling webs 45 are formed. These coupling tracks 45 have a continuous freewheeling region 46 for the coupling pin 37 arranged on the ejection slide 10.
    In Fig. 14, such a coupling track 45 is shown. This has the three sections freewheel area 46, guide and idle area 47 and holding area 48. In this coupling track 45, the coupling pin 37 is movable.
    In contrast, in FIG. 15, the control track 40 formed on a cylinder jacket-shaped inner side of the housing cover 6 is projected onto a surface. Depending on the position of the control pin 38 in the control track 40, the coupling element 9 is coupled via the bayonet-type coupling parts 44 to the thrust element 8 (dome area K) or decoupled (decoupling area EK). In addition, the relative rotational movements of the coupling element 9 and the ejection slide 10 are also aligned with each other about a parallel to the longitudinal direction L via this control track 40
    Rotation axis X controlled. These overall control movements are evident from the movement sequence of the entire drive device 1, which is illustrated and explained in more detail in the following FIGS. 16 to 31.
    For Fig. 16 should first be stated that the drive device 1 is shown in the assembled state without housing cover 6. In addition, the individual components are partially transparent (see dashed line) shown. In Fig. 16, the movable furniture part 2 is in a closed position SS. In addition, the locking device 56 is in locking position VS, since the locking pin 36 (as seen in the top detail) is locked in the locking recess R of the locking guide track 41. The ejection force accumulator 13 presses on the separating element 30 on the locking pin 36 arranged on the ejection slide 10 so that it can not move relative to the inner ejection housing 11 (which is firmly connected to the housing 6, 7). The locking element 58 formed by the synchronization coupling piece 31 forms the latching recess R locking guide track 41. In the lower detail of FIG. 16, moreover, the end region of the coupling element 9 with the bayonet-type coupling parts 44 can be seen. In the closed position SS, the coupling element 9 is not coupled to the push element 8. Furthermore, it is apparent from Fig. 15 that the Einziehkraftspeicher 18 is not stretched. The Einziehriegel 14 contacted with its catching region 59, the thrust nose 60 of the pusher. 8
    If, starting from the closed position SS according to FIG. 16, the movable furniture part 2 is pressed in the closing direction SR, the unlocking takes place as shown in FIG. 17. As a result, the second operating mode B2 of the drive device 1 is initiated. Since the drive device 1 is arranged on the movable furniture part 2 in the preferred embodiment, the housing 6, 7 of the drive device 1 in the closing direction SR (in Fig. 17 to the left) moves. However, since the catch lever 25 rests on the body-fixed and schematically drawn driver 49 is on the catch lever 25, connected to the catch lever 25 thrust element 8 and the voltage applied to the thrust element 8 coupling element 9 which in turn applied to the coupling element 9 ejection slide 10 relative to the rest Moves components of the drive device 1 against the force of the ejection force accumulator 13 until the locking pin 36 abuts against the Abweisschräge 42 of the locking guide track 41 and passes from this to the position shown in FIG. 17 in the ejection section of the locking guide track 41. As a result, the locking device 56 is no longer in the locking position VS but is unlocked (unlocked position ES). The Überdrückweg is about 1 to 3 mm. If the housing 6, 7 is not arranged on the movable furniture part 2 but on the furniture body 51, then the same relative movement between the individual components of the drive device 1 is carried out when overpressing. However, it is then - in contrast to the arrow SR of FIG. 17 - the ejection slide 10 moves over the moving and arranged on the movable furniture part 2 driver 49 to the right in the closing direction SR.
    If then, starting from this overpressure position ÜS, no longer pressing on the movable furniture part 2, the ejection energy accumulator 13 according to FIG. 18 can begin to relax. This relaxing ejection force accumulator 13 thereby presses on the ejection slide 10, whereby the locking pin 36 abuts the front side of the locking element 58 of the synchronizing coupling piece 31. Thereby, the entire synchronization coupling 31 is moved relative to the discharge housing 11,12. By this movement also meshes the rack of the synchronizing coupling 31 with the gear of
    Synchronization counterpart 33 (see detail of Fig. 18). As a result, in the arranged on the other side of the movable furniture part 2, not shown drive device also unlocking triggered (see later Fig. 33).
    Due to the incipient relaxation of the ejection force accumulator 13, the housing 6, 7 is also moved relative to the ejection element 10, the coupling element 9, the thrust element 8 and the catch fork 25 in the opening direction OR. Since the thrust element 8 entrains the Einziehriegel 14 via the thrust nose 60, also the tensioning of Einziehkraftspeichers 18 begins. Therefore, the spring force of the ejection force accumulator 13 is greater than the spring force of Einziehkraftspeichers 18. For explanation, are in Figs. 16 to 18 respectively subregions, especially the outer ejection housing 12, partially hidden, so that a better insight into the inner workings of the ejection housing 11,12 is possible.
    19, the movable furniture part 2 has been further ejected and it is achieved a first slight open position OS. Due to the training of
    Locking guide track 41 in the outer discharge housing 12 is - as can be seen from the bottom of the detail view - the locking pin 36 further deflected so that this the blocking element 58 evades (see also Fig. 11). After the locking pin 36 in this position no longer presses on the synchronizing coupling piece 31, the synchronizing force memory 32 can relax again and moves the synchronizing coupling piece 31 back into the position z. B. according to FIG. 16.
    In Fig. 20, the ejection or opening movement has now continued. The ejection energy storage 13 has already relaxed to a good part, at least so far that the Einziehkraftspeicher 18 is fully stretched. In this fully cocked position of the retractable force accumulator 18, the Einziehriegel 14 has pivoted about the Einziehverbindungszapfen 16 relative to the Einziehschlitten 15 so that the Einziehverriegelungszapfen 23 is locked in the angled end portion of the Einziehverriegelungsbahn 17 (see detail to Fig. 20). By this pivoting movement and the thrust nose 60 of the pusher 8 is no longer in the catching region 59 of the Einziehriegels 14. In this Fig. 20 it can also be seen that the intermediate piece 24 has passed into an end stop of the intermediate piece guide track 39 due to the trailing movement of the damping piston 20. Furthermore, it is particularly important to mention FIG. 20 (as well as to the following figures) that in each case the housing cover 6 is partially inserted. This is so far cut or faded in that in the remaining housing cover 6 shown exactly the control track 40 remains. This illustration is for illustrative purposes only. Thus, it can be seen in FIG. 20 that the control pin 38 on the coupling element 9 has already traveled a considerable part of the ejection control track area 61 (see also FIG. 15).
    21 to 31, an outer region of the housing cover 6 is hidden in the respective upper overall view, so that in the remaining inner region of the housing cover 6, the position of the control pin 38 in the control path 40 is clearly visible. In the lower overall views of these FIGS. 21 to 31, this housing cover 6 is completely hidden. For this, however, an outer region of the coupling element 9 is hidden in each case, so that in the remaining inner region of the coupling element 9, the position of the coupling pin 37 in the coupling track 45 is clearly visible. In between, details of the respective overall view are always displayed.
    According to FIG. 21, the ejection energy accumulator 13 has completely relaxed. As a result, on the one hand, it can be seen in the upper detail of FIG. 21 that the pusher element 8 has moved farther away from the Einziehriegel 14 of the tensioned pull-in device 4. On the other hand, the control pin 38 has moved through the dome control track area 62 of the control track 40. As a result, a rotational movement of the coupling element 9 is triggered relative to the housing cover 6, whereby the bayonet-type coupling part 44 of the coupling element 9 - as shown in the lower detail of Fig. 21 -an engages a protrusion 71 formed on the thrust element 8. As a result, the decoupling position EK is no longer given, but the coupling position K between thrust element 8 and coupling element 9 is reached. From this position shown in FIG. 21, the further opening movement takes place without being influenced by one of the energy storage 13 or 18. The further opening movement can still by the momentum, the force introduced by the ejection force memory 13 in the movable furniture part 2, or by active pulling on the movable furniture part 2 done.
    As a result of this further opening movement, the control pin 38 as shown in FIG. 22 is moved further through the displacement control track area 63 of the control track 40. From the position shown in FIG. 21, the ejection slide 10 can not move further, since an end stop of the locking pin 36 in the discharge housing 11,12 is reached (not shown). Since from reaching the coupling position Kdas the coupling element 9 is moved in a further opening movement by the thrust element 8, a relative movement of the coupling element 9 to the ejection slide 10. Thereby reaches the ejection force storage remote end of the ejection slide 10 arranged coupling pin 37 from the freewheel area 46 in the leadership and Idle region 47 of the coupling track in the coupling element 9. In the lower detail of Fig. 22, this is apparent. For an explanation, in this detail-similar to the upper detail of the housing cover 6 -an outer area of the coupling element 9 is hidden, so that a direct view of the remaining guide track 45 in the coupling element 9 is possible. This, too, is for illustrative purposes only.
    Finally, as shown in FIG. 23, the remaining opening path is completed, so that the catch fork 25 has been deflected into the angled end portion of the guide track 28. By catching fork power storage 26, the catch fork 25 is held in this position. With this remaining opening movement, according to the lower detail of FIG. 23, the coupling pin 37 has moved on the ejection slide 10 into the angled holding region 48 of the coupling web 45 of the coupling element 9. Due to the oblique design of the coupling track 45 in this holding area 48, the coupling element 9 is rotated relative to the ejection element 10. This rotational movement also causes, according to the upper detail of FIG. 23, the control pin 38 has been moved by the deflection control track area 64 of the control track 40. In FIG. 23, the driver 49 just has contact with the catch fork 25.
    In contrast, in FIG. 24 the carrier 49 is already lifted or removed from the catch fork 25. As a result, the movable furniture part 2 is in a freewheel. During this freewheeling all components of the drive device 1 remain in their position. D. h., The Einziehkraftspeicher 18 is stretched and the ejection force accumulator 13 is relaxed.
    As the driver 49 comes into contact with the catch fork 25, the catch fork 25 is released from the angled end portion of the guideway 28 against the force of the catch fork force accumulator 26. According to FIG. 25, the coupling element 9 resting against it has already moved somewhat to the right via the push element 8. Since the ejection element 10 is acted upon by the ejection force accumulator 13, the coupling pin 37 has, according to the lower detail of FIG. 25, applied to a holding surface 72 of the control path 45 which is aligned at least at right angles to the longitudinal axis L or slightly undercut. Since in this case the forces acting from the coupling element 9 substantially perpendicular to the coupling pin 37, the coupling pin 37 is taken from the coupling element 9 in a further insertion movement. In this insertion movement, the control pin 38 moves through the straight clamping control track area 65 of the control track 40. This is mainly caused by the fact that the coupling pin 37 is located in the undercut holding surface 72.
    From the position shown in FIG. 25 to the position shown in FIG. 26 of the ejection force accumulator 13 is stretched by the catch fork 28, the thrust element 8 and the coupling element 9, the ejection element 10 via the voltage applied to the support surface 72 of the control path 45 coupling pin 37 against the Force of the ejection force accumulator 13 is moved. In Fig. 26, the control pin 38 has already covered part of the way in the deflection control track area 66 of the control track 40. This deflection control track area 66 causes a rotation of the coupling element 9 relative to the housing cover 6. By this rotation of the coupling element 9, the coupling pin 37 is simultaneously released according to the lower detail of Fig. 26 from the holding portion 72 of the coupling track 45 and enters a sloping region 73 of the control track 45. When resting in this oblique region 73, the ejection force accumulator 13 is also tensioned. Due to the investment in the oblique region 73, the coupling pin 37 would like to dodge upwards relative to the oblique region 73 or push the coupling element 9 downwards. Both movements are not yet possible in the position shown in FIG. 26. A further downward movement of the coupling element 9 relative to the coupling pin 37 is in fact only possible until the control pin 38 mounted on the coupling element 9 rests in the holding control track region 67 of the control track 40. D. h., In the dash-dotted line in the upper detail of Fig. 26 position of the control pin 38, the relative movement between the housing cover 6 and coupling element 9 is just not so far advanced that the coupling pin 37 in the leadership and no-load area 47 of the coupling web 45th could come. On the other hand, a relative movement of the coupling pin 37 to the coupling element 9 upwards is not possible, since the ejection force accumulator memory facing end of the ejection slide 10 of the locking pin 36 can not move upwards, since the locking pin 36 is still in the clamping portion 78 of the locking guide track 41.
    In Fig. 27, the ejection force accumulator 13 has now been stretched so far that the locking pin 36 is no longer held in the clamping portion 78, but can get into a curved portion 79 of the locking guide track 41. This movement of the locking pin 36 in the cam portion 79 is controlled by the coupling track 45. D. h., As shown in Fig. 27 in the left detail, yes, the coupling pin 37 abuts on the inclined portion 73 of the control path 45. Since the
    Locking pin 36 has reached the curve portion 79, now the ejection slide 10 can rotate.
    This rotational movement is adjusted such that the coupling pin 37 reaches the guide and idle region 47 of the control track 45 when the locking pin 36 is located exactly in a pre-locking section 74 of the locking guide track 41 aligned at right angles to the longitudinal axis L (see FIG. 28). While the locking pin 36 is in this Vorverriegelungsabschnitt 74, the ejection force accumulator 36 is tensioned and a Vorverriegelungsstellung VV is reached. For more information on this pre-locking position VV, reference is made by way of example to WO 2014/165878 A1. This pre-locking position VV allows a push-through protection, so that not undesirable when closing immediately triggers again. It can also be seen in FIG. 28 that immediately after reaching the pre-locking position VV or when this position is reached, the thrust lug 60 of the thrust element 8 engages the insertion latch 14 and releases it from the angled end section of the retraction locking track 17. As a result, the Einziehkraftspeicher 18 begins to relax and the movable furniture part 2 is actively pulled in the closing direction SR.
    In Fig. 29 is about half of the Einziehweges already covered. The Einziehkraftspeicher 18 has thus already relaxed to a good part. This retraction movement is damped by the damping piston 20 of the damping device 5, in that the damping piston 20 acts on the thrust element 8 in a braking manner via the intermediate piece 24. In the upper detail of FIG. 29, the control pin 38 has reached the latching control track area 68 of the control track 40. Due to the oblique configuration of this latching control track area 68, the coupling element 9 is rotated relative to the housing cover 6 upwards. Since at the same time the coupling pin 37 abuts the guide and idle region 47 of the upwardly rotating coupling track 45 of the coupling element 9, and the ejection slide 10 is slightly rotated upwards. As a result, the locking pin 36 passes from the Vorverriegelungsabschnitt 74 according to the right lower detail of FIG. 29 and moves along the A latching slope in the locking recess R of the locking device 56. Thus, the movement of the locking pin 36 from the Vorverriegelungsabschnitt 74 in the locking recess R on the Control track 40 and the coupling track 45 and the associated
    Control pin 38 and uncoupling pin 37 controlled. The control track 40, the control track 38 guided in the railroad track 40, the coupling track 45 in the coupling element 9 and the coupling pin 37 guided in the coupling track 45 and arranged on the ejection slide 10 together form the joint pin the control device for controlling the movement of the arranged on the ejection slide 10 and guided in the locking guide track 41 locking pin 36th
    According to FIG. 30, the locking pin 36 has finally reached the latching recess R and the locking device 56 is in the locking position VS. At the same time, according to the detail at the bottom left, the coupling pin 37 is located in the freewheeling area 46 of the coupling track 45. In the detail shown above, the control pin 38 has moved into the uncoupling control track area 69 of the control track 40. As a result, a rotational movement of the coupling element 9 relative to the housing cover 6 by 70 ° to 150 °, preferably by about 120 °, triggered. In order not to hinder this relatively large rotational movement of the coupling element 9, the coupling pin 37 is in the freewheeling region 46 of the coupling element 9, since the ejection slide 10 can not rotate due to the locking of the locking pin 36. Also, the ejection slide 10 is freely rotatable by this freewheeling region 46 relative to the coupling element 9. In Fig. 30, the drawing-in movement by the retracting device 4 is almost completed.
    In Fig. 31, finally, the closed position SS of the movable furniture part 2 is reached. The control pin 38 is again in a Entkuppelbereich EK the control track 40, whereby the coupling between coupling element 9 and thrust element 8 is repealed. FIG. 31 again corresponds to the starting position according to FIG. 15.
    In Fig. 32, yet another important function of the present drive device 31 can be seen. With the present drive device 1, it is possible in a first operating mode B1, without having to use an overload device or other aids to pull the movable furniture part 2 from the closed position SS in the opening direction OR, without causing damage. D. h., It is not only an opening of the movable furniture part 2 by overpressures and thereby triggered unlocking as possible in the second operating mode B2, but it can also be a pulling on the movable furniture part 2. This is possible because in the closed position SS, the coupling element 9 is decoupled from the thrust element 8. Thereby, the locking position VS of the locking device 56 is maintained and also the ejection device 3 remains unchanged. With this opening by pulling in the first operating mode B1, only the retraction device 4 is actively clamped manually, so that a re-closing guarantees a gentle closing process. For further information on this function, reference may be made by way of example to WO 2014/165873 A1.
    In principle, it is possible for the drive device 1 for the ejection device 3 and the retraction device 4 to have separate carriers for coupling to the movable furniture part 2 or to the furniture body 51. For a simple training and assembly, however, it is preferably provided that the drive device 1 has only one driver 49. About this one driver 49, both the ejector 3 and the retraction device 4 can be triggered. By pulling on the movable furniture part 2 located in the closed position SS, the first operating mode B1 can be activated via this one driver 49. By pressing on the movable furniture part 2 located in the closed position SS, the second operating mode B2 can be activated via this one driver 49.
    In Fig. 33, another function of the drive device 1 is shown. According to this illustration, the unlocking of the locking pin 36 from the catch recess R is not carried out by overpressing, but in that the located on the other side, shown in Fig. 2, the drive device is unlocked by overpressing. About the local locking device 56 and especially by the moving when opening synchronizing coupling piece 31 a movement to the synchronization counterpart 33 and the synchronization rod 76 shown in FIG. 2 is forwarded so that in the apparent in Fig. 33 drive device 1 also at the just beginning opening movement the synchronization coupling 31 is moved. Due to the fact that this synchronization coupling piece 31 is formed integrally with the locking element 58, this locking element 58 does not form a latching recess R more, as a result of which the locking pin 36 due to the slanted locking guide track 41 and due to the spring action by the
    Ejector 13 can get into the ejection section without having to be overpressed himself. For more details on this function, reference is made by way of example to WO 2015/051386 A2.
    Finally, reference is still made to Fig. 34, in which the push-through movement is shown. In this push-through movement, the locking pin 36 moves from Vorverriegelungsabschnitt 74 in the Überdrückbahn 75 of the locking guide track 41. At the same time is also the control pin 38 in the overpressure control track area 70 of the control track 40. By this function, and especially by the Überdrückbahn 75 prevents a direct crushing and thus overpressure and release on closing is prevented. Thus, it can not reach the locking pin 36 directly into the ejection portion of the locking guide track 41.
