    The invention relates to an ejection device for a movable furniture part, with a rotatable ejection element for ejecting the movable furniture part from a closed position to an open position, wherein the ejection element is rotatable in a rotational direction when ejecting the movable furniture part, a ejection element in the opening direction of the movable furniture part kraftbeaufschlagenden ejection force memory and a tensioning device for tensioning the ejection force accumulator via the ejection element. In addition, the invention relates to a piece of furniture with a furniture body, a movable furniture part and such an ejection device.
    In the furniture fitting industry, various types of ejection devices for movable furniture parts, such as drawers, doors or furniture flaps, have been manufactured and sold for many years. Such ejectors are also often referred to as touch-latch mechanisms or tip-on devices. With such ejection devices, a linear movement of the furniture part in drawers or a pivoting movement is triggered in furniture flaps or furniture doors. The movement made in the ejection device does not necessarily have to match the movement path performed by the furniture part. For example, a displaceable ejection element can eject a pivotable furniture door or vice versa.
    A document in which a pivotable or rotatably mounted ejection element acts directly on a furniture door is EP 1 875 021 B1. When opening while the ejection element pivots spring-loaded in a direction of rotation. To stretch the ejection energy storage again, is pressed when closing through the furniture door on the ejection element, causing it to rotate opposite to the original direction of rotation and thereby spans the ejection force storage again. A disadvantage of this design is, inter alia, that the ejection element still remains in an ejection position with fully open furniture door. Thus, this ejection device can stand in the way of stowing utensils in the furniture. It may also be disadvantageous if optionally additionally existing retraction device that the ejection force accumulator is tensioned again only when closing.
    The object of the present invention is therefore to provide a comparison with the prior art improved or prior art alternative ejection device.
    This is achieved by an ejection device having the features of claim 1. Accordingly, the invention provides that during the clamping of the ejection force accumulator, the ejection element is rotatable in the same direction of rotation as when ejecting the movable furniture part. In other words, therefore, the ejection element after ejection simply rotates in the same direction during clamping. As a result, it is not necessary to wait until the movable furniture part for clamping in the closing direction is moved again.
    In principle, it is possible for the ejection element to rotate only a relatively small area during clamping (for example, an eight-turn rotation), while the ejection element rotates by a larger area during ejection (for example, a three-quarter turn). In order nevertheless to bring the necessary force into the ejection energy storage, various translation mechanisms can be provided. It must therefore not be provided that the ejection element rotates during clamping and ejection by the same angle value. It also does not have to be provided that the ejection element rotates 360 ° during clamping and during ejection. This can also only about subareas, z. B. in each case a quarter turn done. For a simple design, however, it is preferably provided that the ejection element during the ejection of the movable furniture part and when tensioning the ejection force accumulator total travels a turning in the form of a full revolution, wherein the ejection element during ejection of the movable furniture part substantially one half of the rotational path and the subsequent tightening of the ejection force accumulator substantially covers the other half of the rotary path. For a simple mounting of the ejection device, a carrier is preferably provided. This carrier may for example have a mounting plate and a lid, whereby the entire ejection device is arranged protected in a carrier designed as a housing. In the presence of such a carrier is preferably provided that the ejection force accumulator acts on the one hand on the carrier and on the other hand on the ejection element.
    In order to enable a transmission of movement from the movable furniture part to the ejection device and vice versa, it is preferably provided that the tensioning device can be coupled to the movable furniture part via a coupling device.
    In principle, it should not be ruled out that the clamping of the ejection force accumulator of the ejection device takes place when it is closing, that is to say when it is pressed onto the movable furniture part. Preferably, however, it is provided that by pulling the movable furniture part in the opening direction of the ejection force accumulator can be tensioned by the clamping device. This pulling tension movement preferably directly adjoins the ejection movement.
    The ejection element may be that element of the ejection device, which also bears directly on the movable furniture part. According to a preferred embodiment, however, it is provided that the movable furniture part from the ejection element is indirectly moved via an clamping element of the clamping device in an open position. The ejection element thus forms that component which is acted upon directly by the ejection force accumulator. The transmission of the rotational movement of this ejection element to the movable furniture part can be carried out via one or more components arranged therebetween (eg translation mechanisms).
    If the ejection force accumulator is stretched when pulling on the movable furniture part, it is preferable to provide a return energy accumulator for moving the tensioning device into a return position.
    Furthermore, a locking device is preferably provided for locking the ejection element in a locking position, wherein the locking device can be unlocked by overpressing the movable furniture part in an overpressure position lying behind the closed position. Such locking devices may be formed, for example in the form of a movable in a heart-shaped cam track control pin. According to a preferred embodiment, a dead center is provided.
    Protection is also desired for a piece of furniture with a furniture body, a movable furniture part (for example in the form of a furniture door, a furniture flap or a drawer) and an ejection device according to the invention for the movable furniture part. Such furniture may additionally also have a, preferably damped, retractor.
    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:

    Fig. 24 to 37 the movement of an ejection device according to the second embodiment.
    Fig. 1 shows a furniture 21 with a furniture body 22 and a movable furniture part 2 in the form of a furniture door. This movable furniture part 2 is pivotally mounted about two hinges 23 on the furniture body 22 about a vertical axis. In at least one of these hinges 23, a damping device, not shown, may be integrated for a closing movement. On the furniture body 22, an ejection device 1 according to a first embodiment is arranged.
    The coupling counterpart 24 of this ejection device 1 is fixed to the movable furniture part 2. Purely by way of illustration, this coupling counterpart 24 is also located directly in the region of the ejection device 1. In fact, of course, only that coupling counterpart 24 on the movable furniture part 2 is present. In principle, it is possible in all embodiments that the ejection device 1 is arranged on the movable furniture part 2 and the coupling counterpart 24 is arranged or formed on the furniture body 22. As a result, the ejection device 1 abuts the furniture body 22, as it were.
    In Fig. 2, the ejection device 1 according to the first embodiment can be seen in an exploded view. This ejection device 1 has, as a base element, a carrier 3, via which the ejection device 1 is mounted on the furniture 21. Together with a cover not shown, this carrier 3 can form a housing for the remaining components of the ejection device 1. In the carrier 3, the clamping element 7 is slidably mounted. The displacement movement of this clamping element 7 is damped by the damping device 36. The Rückholkraftspeicher 15 engages on the one hand on the clamping element 7 and on the other hand on the carrier 3. The tensioning element 7 forms, together with the motion transmission element 8 designed as a stop, the tensioning device 6. Furthermore, an ejection element 4 is rotatably mounted about the axis of rotation X in the pivot bearing 57 of the carrier 3. The ejection force accumulator 5 designed as a tension spring engages on the ejection element 4 on the one hand via the ejection element energy storage base 29 and on the other hand on the carrier energy storage base 32 of the carrier 3. The deflection element 38 is mounted pivotably about the pivot bearing pin 58 on the clamping element 7. Between deflecting element 38 and clamping element 7, a deflection spring 39 designed as a tension spring is additionally provided.
    Furthermore, a coupling device 26 is provided. This coupling device 26 is mainly formed by the coupling piece 25 and the coupling counterpart 24. The coupling piece 25 is slidably mounted in the guide track 28 of the clamping element 7. Also, the coupling and decoupling element 27 is slidably disposed in this guideway 28. In addition, a coupling lever 41 is provided, which is rotatably mounted in the pivot bearing 44 of the clamping element 7 and on the one hand in the slot 48 of the coupling piece 25 is guided and on the other hand hinged to one end of the coupling counter-piece stop 43. Furthermore, a trained as a tension spring coupling power storage 40 is provided, which acts on the one hand on the coupling and decoupling element 27 and on the other hand on the coupling piece 25. In addition, a likewise designed as a tension spring coupling lever force accumulator 42 is provided. This coupling lever force accumulator 42 engages on the one hand on the coupling lever 41 and on the other hand on the clamping element 7. Furthermore, a connectable to the carrier 3 head portion 37 is provided.
    In Fig. 3, the ejection device 1 according to the first embodiment can be seen in the assembled state. Already in this illustration according to FIG. 3, it can be clearly seen that the carrier-force storage base 32 and the discharge-element energy storage base 29 lie in a plane containing the rotation axis X of the discharge element 4 and the line of action W. Furthermore, the trained on the coupling and decoupling element 27 stop 45 can be seen. It can also be seen in this FIG. 3 that the ejection element 4 bears against the triggering device 35 formed as a stop on the clamping element 7.
    FIG. 4 shows a plan view of the ejection device 1 according to FIG. 3. The movable furniture part 2 is in a closed position SS. The locking device 17 is in the locking position VS, in which the line of action W of the ejection force memory 5 through the axis of rotation X leads. The effective direction of the line of action W is indicated by the arrow and points in the closing direction SR. Since this line of action W leads through the axis of rotation X, the force of the tensioned ejection force accumulator 5 can not unfold. This will do that
    Ejector 4 held in a dead center, so to speak. The carrier-energy storage base 32 (together with the carrier 3), the ejection force memory 5 and the ejection element 4 thereby jointly form the locking device 17. The coupling device 26 is in the coupling position K, since the coupling piece 25 is coupled to the coupling counterpart 24.
    If starting from this position shown in FIG. 4 in the closing direction SR is pressed onto the movable furniture part 2, this movable furniture part 2 passes into the overpressure position ÜS according to FIG. 5. The clamping element 7 is likewise moved in the closing direction SR via the coupling counterpart 24. whereby the stop of the triggering device 35 rotates the ejection element 4 in the direction of rotation D-that is, counterclockwise-about the axis of rotation X. By this overpressure thus reach the axis of rotation X and the line of action W in a mutually spaced, relative unlocking position ES. Thus, the locking device 17 is unlocked.
    Starting from this unlocking position according to FIG. 5, the ejection force accumulator 5 can relax, as a result of which the ejection element 4 continues to rotate in the direction of rotation D (see FIG. 6). As a result, the end of the ejection element 4 facing away from the ejection element power storage base 29 comes into contact with the ejection stop 46 formed on the clamping element 7. This implies that the entire clamping element 7 is moved in the opening direction OR relative to the carrier 3, which in turn causes the movable furniture part 2 to move into one , although still minor, open position OS arrives. At the same time, the ejection element 4 also pivots the deflection element 38 clockwise against the force of the deflection force accumulator 39.
    In Fig. 7, the ejection force memory 5 has further relaxed, whereby the furniture part 2 (represented by the coupling counterpart 24) was moved even further in the open position OS. The movable furniture part 2 is thus ejected indirectly from the ejection element 4 via the clamping element 7 and the coupling piece 25. Since the tensioning element 7 moves in the opening direction OR, the return energy accumulator 15 designed as a tension spring also begins to cock.
    In Fig. 8, a quarter turn of the ejection element 4 is completed. The ejection force accumulator 5 has already been substantially relaxed by half. The movable furniture part 2 is in the open position OS, the locking device 17 in the unlocking position ES and the coupling device 26 in the coupling position K. The deflection power accumulator 39 is fully stretched.
    9, since the ejection element 4 has already moved further, the end of the ejection element 4 facing away from the ejection element energy storing base 29 is again moved in the opposite direction (i.e., to the right in this case). As a result, the deflection force accumulator 39 can relax again, whereby the deflection element 38 is tracked to the ejection element 4.
    Between Fig. 9 and Fig. 10, the ejection device 1 reaches a position, not shown, in which the locking position VS opposite dead center is reached, in which the carrier-energy storage base 32, the ejection-element storage base 29 and the rotation axis X in plan view in a line lie. In order for the ejection element 4 to continue to move on the basis of this neutral position or dead center position, however, the deflection force accumulator 39 continues to relax, as a result of which the deflecting element 38 moves the ejection element 4 into the position according to FIG. In this position, the ejection path A of the ejection device 1 is completed. From this position thus begins the clamping path S, in which actively on the movable furniture part 2 is pulled. Since the clamping element 7 is coupled via the coupling device 26 with the movable furniture part 2, and the ejection element 4 is moved as shown in FIG. 11 via the formed as a stop motion transmission element 8 in the opening direction OR. As a result, when the ejection force accumulator 5 is tensioned, the ejection member 4 is rotated in the same rotational direction D (counterclockwise) as when the movable furniture member 2 is ejected.
    According to Fig. 12, the ejection element 4 through the
    Motion transmission element 8 even further rotated in the direction of rotation D about the axis of rotation X.
    In Fig. 13, finally, the clamping path S of the clamping device 6 is completed. Thus, the ejection device 1 has moved in the opening direction OR by the opening stroke O (consisting of ejection path A and tensioning path S). At the same time, the ejection element 4 has performed a full revolution, whereby again the locking position VS is reached, in which the line of action W of the ejection force memory 5 leads through the axis of rotation 5. The Rückholkraftspeicher 15 is fully stretched. The stopper 45 on the coupling and decoupling element 27 rests against the head part 37, whereby the predetermined opening path VO for the control device for the coupling device 26 formed by the coupling and decoupling element 27 is reached or covered. The tip 47 of the coupling and Entkoppelements 27 is still in the foremost region of the coupling piece 25, whereby the head portion of the coupling piece 25 is still spread or the two mutually spaced by a gap extensions of the head portion can not bend each other. The coupling position K between the head region of the coupling piece 25 and the receiving region of the coupling counterpart 24 is given by a positive fit.
    If, starting from this position according to FIG. 13, further pulling is made on the movable furniture part 2, a path-controlled decoupling of the coupling device 26 takes place (see FIG. 14). First, the clamping element 7 is further moved in the opening direction OR on the coupling piece 25. However, since the, a control device forming coupling and decoupling element 27 is present at the head part 37, only the coupling piece 25 moves together with clamping element 7 in the opening direction OR relative to the carrier 3. This removes the tip 47 of the coupling and decoupling element 27 from the head region of Coupling piece 25, whereby this head area is less strong or no longer spread. The extensions of the head area can thus bend each other. As a result, the Entkoppelstellung EK is reached and there is only a loose connection between the head portion of the coupling piece 25 and the receiving area of the coupling counterpart 24 before. Thus, the no longer spread coupling piece 25 from the coupling counterpart 24 of FIG. 14 can already solve. In the relative movement of the coupling and decoupling element 27 to the coupling piece 25 also spans the
    Coupling force memory 40, since this one hand acts on the coupling piece 25 and on the other hand on the coupling and decoupling element 27.
    Once the coupling counterpart 24 has completely detached from the coupling piece 25, the movable furniture part 2 is in a freewheel. At the same time, the coupling force memory 40 can relax again, whereby the coupling piece 25 is moved in the closing direction SR relative to the clamping element 7. As a result, the coupling lever 41 pivots about the pivot bearing 44. With this movement, the coupling counterpart stop 43 is moved out of the clamping element 7 also by the coupling lever force accumulator 42 relaxes. When moving back the coupling piece 25 of the head portion of this coupling piece 25 passes between the side walls of the coupling piece guide 49, whereby the spaced-apart parts of the head portion of the coupling piece 25 are pressed to each other. As a result, the tip 47 of the coupling and decoupling element 27 does not travel all the way to the front in the coupling piece 25. The coupling power accumulator 40 can thus not fully, but only in about half relax.
    However, in order nevertheless to drive the coupling piece 25 completely into the coupling piece guide 49, the coupling lever force accumulator 42 relaxes according to FIG. 16 and pivots the coupling lever 41 until the coupling piece 25 bears against the stop 59 of the clamping element 7. As a result, the coupling counterpart stop 43 is fully extended. The tip 47 of the coupling and decoupling element 27 is not yet completely in the foremost region of the coupling piece 25th
    From FIG. 16 or already from FIG. 15, the return energy accumulator 15 also begins to relax, as a result of which the position according to FIG. 17 is initially reached.
    As a result, the tensioning element 7 is further moved into the position shown in FIG. 18 via the relaxing restoring force accumulator 15, until finally the return position R is reached in FIG. 19. From FIG. 18 to FIG. 19, this return movement is damped by the damping device 36. The movable furniture part 2 is still in an open position OS. The locking device 17 is in the locking position VS.
    If, finally, according to FIG. 20, the movable furniture part 2 is also closed, the coupling counterpart 24 first comes into contact with the coupling counterpart stop 43. As a result, the coupling piece 25 is first moved in the opening direction OR via the rotary movement of the coupling lever 41, as a result of which the first is not spread Head portion of the coupling piece 25 engages in the receiving area of the coupling counterpart 24. Since then the coupling piece 25 is no longer held narrowing between the side surfaces of the coupling piece guide 49, the coupling energy accumulator 40 has relaxed as shown in FIG. 20, whereby the tip 47 of the coupling and decoupling element 27 is again completely penetrated into the head region of the coupling piece 25 and thereby spreads this header. Thus, in Fig. 20 again the coupling position K of the coupling device 26 is reached. This FIG. 20 also corresponds again to the starting position according to FIG. 4.
    In Fig. 21, a furniture 21 including a furniture body 22 and a movable furniture part 2 with a second embodiment of an ejection device 1 is shown. Again, the movable furniture part 2 is in turn hingedly connected by hinges 23 to the furniture body 22. On the movable furniture part 2, the coupling counterpart 24 of the ejection device 1 is attached.
    In the exploded view according to FIG. 22, the second exemplary embodiment of the ejection device 1 can be seen in detail. Again, a carrier 3 is present, which together with a lid, not shown, can form a housing for the remaining components of the ejection device 1. In the carrier 3, the clamping element 7 is slidably mounted. This tensioning element 7 is supported on the carrier 3 in a damped manner via the damping device 36. About the Rückholkraftspeicher 15, the clamping element 7 is connected to the carrier 3. In the clamping element 7, a guideway 28 for the coupling and decoupling element 27 is provided. This coupling and decoupling element 27 is biased by a coupling power accumulator 40 in the left direction relative to the clamping element 7. The coupling power accumulator 40 is formed in this case as an approximately V-shaped tension spring, this tension spring is held with their ends in the clamping element 7 and rests in a central region on the coupling and decoupling element 27. Furthermore, a coupling element clamp 56 connected to the carrier 3 is provided, which can be applied to the stop 45 of the coupling and decoupling element 27. In addition, a head part 37 is attached to the support 3 in this embodiment. On the clamping element 7 a total of three ejection stops 46 are provided, which correspond to the discharge element 4 arranged on the discharge rollers 51. The ejection element 4 itself is rotatably mounted on the pivot bearing 57 of the carrier 3 via the rotation axis X. In addition, the tensioning roller 52 is arranged on the ejection element 4. An eccentric pin 50 is arranged eccentrically on the ejection element 4. The ejection force accumulator 5 is connected on the one hand via the ejection element-power storage base 29 with the ejection element 4 and on the other hand via the carrier-power storage base 32 to the carrier 3. Furthermore, a release device 35 is provided, which is formed in this embodiment by the trigger element 55, the release spring 54 and the trip bar 53. This release bracket 53 is held in the recess 60 of the carrier 3.
    In Fig. 23, the second embodiment of the ejection device 1 is shown in the assembled state. In this case, the stopper 45 of the coupling and decoupling element 27 bears against the coupling element clamp 56. In addition, it can be seen that the carrier-force storage base 32 and the ejection element-energy storage base 29 in the illustrated locking position VS lie in a plane containing the axis of rotation X of the ejection element 4 and the line of action W.
    A top view of the ejection device 1, which corresponds to FIG. 23, is shown in FIG. 24. The position of the coupling counterpart 24 corresponds to the position of the movable furniture part 2, which is in the closed position SS. In addition, the locking device 17 is in the locking position VS, since the line of action W of the ejection force memory 5 through the axis of rotation X leads. The release bracket 53 rests with its end face on the eccentric pin 50. At the knee area of this release bar 53, in turn, there is an end area of the triggering element 55. The other end of this trigger element 55 is applied to the coupling counterpart 24. Although the head region of the coupling piece 25 is spread apart by the tip 47 of the coupling and decoupling element 27, since the head region of the coupling piece 25 is not in the receiving region of the coupling counterpart 24, the coupling device 26 is still in a decoupling position EK.
    If, starting from this closed position SS according to FIG. 24, the movable furniture part 2 is pressed in the closing direction SR, then the movable furniture part 2 reaches the overpressure position ÜS according to FIG. 25. Since the triggering element 55 rests against the coupling counterpart 24 and the yielding release bracket 53 in turn rests on the trigger element 55 via its knee region, the end face of the release bracket 53 is pressed onto the eccentric pin 50, whereby the ejection element 4 is rotated in the direction of rotation D about the axis of rotation X. As a result, the axis of rotation X and the line of action W passes into a mutually spaced, relative unlocking position ES. Thus, the locking device 17 is unlocked. (In the exemplary embodiments illustrated here, the ejection element-force storage base 29 is always moved for the locking.) In principle, however, it would also be possible for the rotation axis X to be displaced so that it comes at a distance from the line of action W. In this way, the line of action W would remain in With respect to the carrier 3 unchanged, but the axis of rotation X would move relative to the carrier 3.)
    As soon as an operator of the furniture 21 no longer presses on the movable furniture part 2, as shown in FIG. 26, the ejection energy accumulator 5 begins to relax further. This ejection force memory 5 takes the ejection element 4 with it and rotates it further in the direction of rotation D in the counterclockwise direction. Thereby, the first of the three discharge rollers 51 comes in contact with a first of the three discharge stops 46, whereby the clamping element 7 is moved by the discharge element 4 in the opening direction OR. Since the coupling piece 25 is formed integrally with the clamping element 7, the coupling counterpart 24 and with this the movable furniture part 2 in the opening direction OR is moved over the head portion of the coupling piece 25. As a result, the movable furniture part 2 is in a - although slightly open - open position OS. The locking device 17 is in an unlocking position ES. The coupling device 26 is still in a decoupling EK. According to FIG. 26, the tensioning element 7 has already been moved slightly in the opening direction OR relative to the carrier 3. However, since the coupling element clamp 56 is fixed to the carrier 3 and the stopper 45 bears against this coupling element clamp 56, the coupling and decoupling element 27 forming the control device does not move with the clamping element 7 in the opening direction OR. This removes the tip 47 of the coupling and Entkoppelements 27 from the head portion of the coupling piece 25. The head portion of the coupling piece 25 is thus already spread less.
    Since, according to FIG. 27, the tip 47 is moved back further relative to the coupling piece 25, the head region of the coupling piece 25 is no longer spread and this head region can slide into the receiving region in the coupling counterpart 24 due to the mutually bendable design of its two extensions. As a result, however, only a loose connection between coupling piece 25 and coupling counterpart 24 is achieved. Due to the relative movement of the coupling and decoupling element 27 to the clamping element 7 along the guideway 28 27 of the coupling power accumulator 40 is stretched as shown in FIG. As shown in Fig. 27, the ejection element 4 has already rotated further, whereby a second ejection roller 41 comes into contact with a second ejection stop 46.
    Upon further rotation of the ejection element 4 as shown in FIG. 28, one end of the elastic coupling element clamp 56 comes into contact with the ejection element 4, whereby the Koppelementspanner 56 is slightly bent to the left. As a result, the stopper 45 of the coupling and decoupling element 27 is no longer held by the coupling element clamp 56, as a result of which the coupling force accumulator 40 can relax. As a result, the coupling and decoupling element 27 again moves relative to the clamping element 7 in the opening direction OR, whereby the tip 47 of the coupling and Entkoppelements 27 passes into the head region of the coupling piece 25 and spreads it. As a result, a secure form-fitting hold and thus the coupling position K between the coupling piece 25 and the coupling counterpart 24 is achieved, which is insoluble without a relative movement of the coupling and decoupling element 27 to the coupling piece 25.
    As shown in FIG. 29, half turn of the ejection element 4 is completed. Thus, the ejection energy storage 5 has completely relaxed and the ejection element 4 is again in a neutral position. The discharge path A of the ejection device 1 is thus completed. The Rückholkraftspeicher 15 have already stretched in about half. From this Fig. 29 is now pulled in the opening direction OR on the movable furniture part 2.
    As a result of this further pulling movement, which has already begun in FIG. 30, the clamping element 7 is moved further in the opening direction OR relative to the carrier 3. Since a third ejection roller 51 is still in contact with a third ejection stopper 46, the ejection member 4 is further rotated in this same tension of the ejection force memory 5 in the same rotational direction D as in the ejection of the movable furniture part 2. At the same time, the tension roller 52 comes into contact with the motion transmission element 8. This formed as a stop motion transmission element 8 forms together with the clamping element 7, the tensioning device 6 for the ejection force memory 5. This is already stretched in Fig. 30 to a part.
    According to FIG. 31, the movable furniture part 2 has been moved even further in the opening direction OR and at the same time the ejection element 4 has been rotated further in the direction of rotation D, whereby the eccentric pin 50 bears against a flank of the release bracket 53 and already bends this release bracket 53 slightly to the right due to its compliance, as you can see in the detailed picture on the right side.
    In FIG. 32, the movable furniture part 2 has been moved even further in the opening direction OR, whereby the ejection element 4 has turned even further. As a result, the eccentric pin 50 bends the release bracket 53 even more clearly (see detail on the top right).
    Upon further movement of the eccentric pin 50 finally passes the release bracket 53, whereby both components return to their initial position shown in FIG. 33. By the release spring 54 and the position of the trigger element 55 is again adapted so that the trigger member 55 protrudes by the gap from the carrier 3. According to FIG. 33, the tensioning path S is also completed, which, together with the discharge path A, results in the opening travel O of the ejection device 1. In the movement of the ejection device 1 of Fig. 32 in Fig. 33, the stopper 45 of the coupling and decoupling element 27 comes into contact with the head part 37. The predetermined opening stroke VO is reached. As a result, this coupling and decoupling element 27 is moved under load of the coupling force memory 40 relative to the clamping element 7, whereby the tip 47 of the coupling and decoupling element 27 from the head portion of the coupling piece 25 passes and the extensions of this head area no longer spreads. As a result, the decoupling position EK of the coupling device 26 is achieved. However, a loose connection between the head region of the coupling piece 25 and the receiving region of the coupling counterpart 26 is still present.
    If, starting from this position according to FIG. 33, further pulling on the movable furniture part 2, the coupling counterpart 24 can detach from the coupling piece 25 by mutually bending the extensions of the head region and the loose connection is also canceled.
    From reaching this Entkoppelstellung EK and the Rückholkraftspeicher 15 can relax again and moves first the clamping element 7 in the closing direction SR until reaching the position shown in FIG. 35. At the same time with this movement or from the time from which the stop 45 no longer Head part 37 is applied, the coupling force accumulator 40 can relax. As a result, the tip 47 of the coupling and decoupling element 27 is moved into the head region of the coupling piece 25, whereby it is spread again.
    In Fig. 36, the Rückholkraftspeicher 15 has completely relaxed. This return movement is damped by the piston of the damping device 36. As a result, the return position R of the return device 13 or the return force accumulator 15 is reached. The movable furniture part 2 - represented by the coupling counterpart 24 - is still in the open position OS.
    Finally, if, according to FIG. 37, the movable furniture part 2 is also moved in the closing direction SR, the movable furniture part 2 reaches the closed position SS. In this closed position SS, the coupling counterpart 24 again lies against the triggering element 55. The locking device 17 is in the locking position VS. The coupling device 26 is in the decoupling EK. FIG. 37 again corresponds to the starting days according to FIG. 24.
    Finally, it should be noted that in the embodiments the same functional components are provided with the same reference numerals. Thus, the advantages and possibilities mentioned for the embodiments apply mutatis mutandis to the other embodiments.
