If the device is arranged on the movable furniture part, then the driver is advantageously formed on the guide means of the furniture and / or on the furniture body, advantageously fixed in position to the furniture body. If the device is arranged on the guide means of the movable furniture part and / or on the furniture body fixed in position to the furniture body, the driver is preferably formed on the movable furniture part.

The essential aspect of the invention is now to be seen in the fact that a coupling device is provided which is effective in a charging operation of the energy storage between ejector and energy storage, wherein the ejector is configured in such a way that it in the region of the end of his path during the opening process of movable furniture part coupled with the coupling device, and that for a subsequent closing operation of the movable furniture part and an associated charging of the energy accumulator, the coupling between the ejector and energy storage device via the coupling device is effective clearance.

As a result, a disturbing to the user noise, such as a clunk, completely avoided or greatly reduced when the driver meets the ejector.

In a preferred variant of the invention, the coupling device is not in operative connection with the ejector during an opening movement of the movable furniture part, in particular during the unloading process of the energy accumulator.

Furthermore, it is proposed that a movable control member is provided on the ejector in a manner that the ejector with the coupling device in operative connection for a charging operation of the energy storage device can be brought when the movable furniture part occupies a predetermined position with respect to the ejector.

For example, the ejector with the coupling device can be brought into operative connection when the movable furniture part leaves the ejector during the opening process.

The movable control member may be formed as a pawl member with a hook portion.

Advantageously, the movable control member is arranged on the ejector such that it is provided with a driver, e.g. the movable furniture part or the guide means of the furniture part and / or the furniture body, cooperates such that upon movement of the movable furniture part in the opening direction of the ejector is moved to an end position.

For example, the movable control member is formed on the ejector such that the movable control member can couple only in an opening movement of the movable furniture part with the driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body.

During a movement of the movable furniture part, in particular an opening movement is a coupling of a coupling member of the coupling device with the ejector instead, advantageously at the end of a discharge process of the energy storage, for example, after completion of the discharge. The coupling can take place such that the movable control member of the ejector is pivoted during the opening movement of the movable furniture part in the direction of the coupling member in play-free contact with the coupling member.

It is also conceivable that the movable control member is arranged on the power storage and / or on the coupling device.

It also proves advantageous that the ejector assumes a play-free coupling with the coupling device when the ejector returns from its end position to a waiting position, in particular during the opening process of the movable furniture part.

Advantageously, the waiting position forms a start position of the movement of the ejector during the closing operation of the movable furniture part for loading the force accumulator via the coupling device.

For example, the ejector coupled in the reverse movement of the ejector relative to the remaining device from the end position to the waiting position of the ejector on the movable control member without play with the coupling device, for example with a coupling member of the coupling device.

Moreover, it is advantageous that the ejector is in the waiting position under a bias.

Advantageously, the ejector is pressure-loaded in the waiting position.

Optionally, the coupling device is in the waiting position under a bias, in particular, a coupling member is under a pressure-loaded bias.

For example, the ejector is coupled to the coupling device such that a pressure force is transmitted from the ejector to the coupling device.

It is also advantageous that the device comprises an elastic member, wherein the elastic member urges the ejector in its waiting position. In particular, the elastic member urges the ejector from its final position to its waiting position.

Advantageously, the ejector undergoes a reversal of motion at its end position by a force of the elastic member.

The elastic member can act on the ejector such that the ejector in and / or during a movement of the movable furniture part in the opening direction, for example in the opening process, can be brought by the elastic member from the end position of the ejector in a waiting position.

The elastic member may be used as a spring element, e.g. a coil spring, a leaf spring, a leg spring, an elastic rubber element or an elastic plastic element may be configured. It is also conceivable that the elastic member is composed of a combination of said elements.

Advantageously, the elastic member acts damping and / or resilient.

Advantageously, the elastic member pushes in the waiting position on the ejector, in particular, the elastic member is in the waiting position of the ejector under a bias.

Moreover, it is advantageous if the movable control member is arranged on the ejector so that it is in the opening operation of the movable furniture part of a driver of the movable furniture part and / or the guide means of Furniture part and / or the furniture body separates so that it is no longer in contact with it, for example, when the elastic member has reached a maximum force, for example a spring tension, especially when the ejector has reached its final position. As a result, a coupling of the ejector with the driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body is solved.

Advantageously, the elastic member on the housing of the device, for example, the base plate of the housing and / or a cover member of the housing, in particular a side wall of the housing is arranged.

The elastic member may also be formed on the ejector.

By the opening movement of the movable furniture part, the elastic member, e.g. be loaded by a pressure force of the ejector on the elastic member, advantageously via a movement of the ejector in the direction of the end position.

It is also conceivable that the elastic member is formed separately from the device and the ejector. For example, the device may be arranged with the ejector on the movable furniture part and the elastic member on the furniture body or the guide means of the furniture part.

The elastic member preferably has a comparatively very small spring force. Advantageously, the elastic member absorbs a comparatively small kinetic energy of the ejector and / or the movable furniture part and / or the driver of the guide means of the furniture part or of the furniture body.

In this way, an opening and / or closing movement of the movable furniture part can be made pleasant for a user. Advantageously, the movement of the movable furniture part without abrupt change in speed, in particular the opening movement of the movable furniture part is not appreciably changed by an action of the elastic member for a user.

It is also conceivable that the elastic member is formed on the energy storage.

Preferably, the elastic member, which is formed on the force accumulator, acts on the ejector via the coupling device, which is in play-free operative connection with the ejector.

The elastic member may act between the housing of the device and the ejector of the device and / or between the ejector and the coupling device and / or between the coupling device and the energy accumulator.

In an advantageous embodiment of the invention, the movable control member is pivotable, in particular rotatably arranged on the ejector of the device.

It is also advantageous that the movable control member pivots away from the driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body with a maximum power load of the elastic member, advantageously rotates away. In particular, at the end position of the ejector, the elastic member is loaded with a maximum force.

In an advantageous embodiment of the invention, the pivoting and / or rotational movement of the movable control member is designed such that the coupling of the ejector with the driver of the movable furniture part and / or the Guide means of the furniture part and / or the furniture body is solved.

Moreover, it is advantageous that the movable control member is in particular pivotally guided such that the ejector of the device can be brought in play-free operative contact with the coupling device in a movement of the movable furniture part in the opening direction.

For example, the pivoting and / or rotational movement of the movable control member acts in such a way that the ejector and / or the movable control member of the ejector by the pivoting and / or rotational movement with the coupling device is brought into contact such that a motion transmission in the closing of the movable furniture part of the ejector on the coupling device on the energy storage is possible without play.

In an advantageous embodiment of the device, a guide slot is formed on the housing of the device, in particular on the base plate of the housing and / or on the ejector.

By the guide slot, the movable control member and / or the ejector can be guided so that the ejector with a coupling member of the coupling device can be brought into play-free contact.

Advantageously, the movable control member and / or the ejector are guided by means of the guide slot such that the coupling of the ejector is solved with the driver after reaching the end position of the ejector in the opening operation of the movable furniture part.

In a further variant, a particular backlash-free coupling of the ejector with a coupling member of the coupling device is achieved during a movement of the movable furniture part in the closing direction after completion of the charging process of the energy storage device of the device.

Advantageously, the movable control member is configured in such a way that after a charging operation of the energy storage moves the movable control member and / or pivoted and / or rotated that the coupling of the ejector is solved with the coupling member of the coupling device.

It is also advantageous that a coupling member of the coupling device is movably guided with a first end on a guide slot.

It is also conceivable that the guide slot is designed such that the coupling member is guided with its first end on the guide slot parallel to a closing and / or opening direction of the movable furniture part.

Advantageously, a coupling member of the coupling device can couple with a first end to the ejector.

It is also preferred that the coupling device is not detachably and without play connected to the energy storage.

An inventive furniture 50 with a box-shaped furniture body 51 and a guide means 52 movably guided drawer 53 is in FIG. 1 shown. The drawer 53 comprises a drawer bottom 54, a drawer front 55, side walls 56 and a drawer rear wall 57. For guiding the drawer 53, two equally acting guide means 52 are provided between each side wall 56 of the drawer 53 and an associated body side wall 59. On an underside of the drawer bottom 54, a device 58 according to the invention (shown in dashed lines) for moving or ejecting the furniture part designed as a drawer 53 in the opening direction M1 is arranged.

FIG. 2 shows the exploded view of the device 58, which is designed as an ejector unit 1 for the drawer 53.

The ejector unit 1 is used for power-assisted ejection of the drawer 53 over a first part of the opening movement of the drawer 53 from a closed Position relative to the furniture body 51 in the opening direction M1 of the drawer 53rd

The drawer 53 is slidably mounted on the furniture body 51 in the direction of M1 and M2 via the guide means 52, for example, two similar partial or full extension. The ejector unit 1 may alternatively be arranged on the furniture body 51 or on the guide means 52 of the furniture 50.

The ejector unit 1 comprises, inter alia, a base plate 2, a force accumulator 3, a coupling device 4, an ejector 5, a trigger 6 and a locking member 7.

A housing of the ejector unit 1 comprises the base plate 2 and a cover component 9, which consists of FIG. 9 is apparent. The ejector unit 1 can be arranged via the housing or via the cover component 9 and / or the base plate 2 on the underside of the drawer bottom 54 and / or on the guide means 52.

On the base plate 2 holding sections, guide contours, stop members and / or receiving portions for connection of the individual components of the ejector unit 1 are formed. The base plate 2 is designed essentially as a rectangular, elongated or strip-shaped component with a comparatively small height h of, for example, approximately 5 to 15 millimeters. The base plate 2 further has a width b of about 4 to 10 centimeters and a length g.

According to the embodiment shown, the energy accumulator 3 comprises two parallelly arranged similar spiral springs 10, 11, which form a spring assembly. At a first end 12 of the force accumulator 3, the coil springs 10, 11 are arranged on an adjustable fixed bearing 13. The fixed bearing 13 comprises a movable bearing part 14, on which the coil springs 10, 11 are detachably but firmly received and an adjusting member 15 with an operating section 16, via which a user can set a position of the end 12 of the energy accumulator 3 from the outside variable fixed position.

As a result, a force effect of the energy accumulator 3 can advantageously be preset on the drawer 53 during the opening process of the drawer 53.

At a second end 17 of the energy accumulator 3, the associated ends of the coil springs 10, 11 are fixed to a carriage-like moving element 18. The slide-like movement element 18 is guided via an associated guide contour 19 on the base plate 2 movable in a direction of movement P1 and an opposite direction of movement P2 linear.

The directions of movement P1 and P2 of the moving element 18 (see FIG. FIGS. 2, 3 ) run parallel to the opening direction M1 of the drawer 53 and a closing direction M2 opposite thereto.

If the ejector unit 1 is fixedly arranged on the furniture body 51 and / or on a stationary part of the guide means 52, the opening direction of the drawer 53 corresponds to the direction P1 and the closing direction of the drawer 53 to the direction P2.

In addition, it is assumed that a mounting state of the ejector unit 1 on the drawer bottom 54.

The Figures 3 . 7 . 8th show the ejector unit 1 in a clamping state of the force accumulator 3, in which the coil springs 10, 11 stretched or stretched claimed, here is the moving member 18 against a retracted in the direction P2 position on the base plate 2 in the direction P1 offset and in one Clamping position held.
The Figures 5 . 6 show the ejector unit 1 in a discharged basic state of the energy accumulator 3, in which the coil springs 10, 11 are further biased to train, but with a smaller amount, and have a length L1.

In the clamping state of the force accumulator 3, the coil springs 10, 11 have a length L2 which is greater than L1.

On the movement element 18, a holding member 32 with a stop element 26 is present. The stop element 26 is in a force-assisted opening operation in contact with an ejector. 5

The ejector 5 is in particular only linearly movable or parallel to the direction of movement of the moving element 18 in the directions P1 and P2 through the coupling device 4, the force memory 3 and the movement member 18 preferably exclusively during the closing operation of the drawer 53 - and movable. For this purpose, a linear guide 20 is formed on the base plate 2, which on guide portions z. B. is tuned on one side of the ejector 5.

An effected by the ejector unit 1 opening operation of the drawer 53 takes place exclusively on a direct operative connection of the energy accumulator 3 via the movement in the direction of P2 moving member 18 on the ejector 5. For this purpose, a stop member 26 is formed on the movement element 18, which is advantageously designed elastically and thus prevents a user disturbing noise when hitting the movement member 18 on the ejector 5 in the opening operation of the drawer 53 or at least dampens ( FIG. 3 . 4 . 5 ).

A front gap adjusting arrangement 8, which is formed on the ejector 5, comprises a housing 45 and an adjusting screw 22 with a contact section 21. The adjusting screw 22 has an external thread which cooperates with an internal thread on the housing 45. By manually rotating an operating section 46 of the adjusting screw 22 by a user, a position of the contact section 21 of the adjusting screw 22 in the direction of P1 or P2 is adjustable depending on the direction of rotation. The adjusting screw 22 is in particular designed to be self-locking relative to the housing 45. By the Position specification of the adjusting screw 22 is a measure of a front gap between the drawer front 55 of the furniture body 51 closed drawer 53 and end faces of the furniture body 51 can be specified.

The contact portion 21 of the screw 22 is in the tensioned or charged state of the energy accumulator 3 to a driver 23, which forms a stop for the contact portion 21 in corresponding operating states. The in the FIGS. 3 to 8 only indicated by dashed lines driver 23 may for example be present on a fixed rail of the guide means 52 or be attached to the furniture body 51 when the ejector unit 1 is arranged on the drawer 53.

If, however, the ejector unit 1 is arranged on the furniture carcass 51 or on a positionally fixed part of the guide means 52 of the furniture 50, the driver 23 can be present on the drawer 53 and thus movably on the furniture carcass 51.

Is starting from the basic position of the ejector unit 1 according to FIG. 3 a lock on the ejector unit 1 canceled, which FIG. 4 shows and is explained in more detail below, the tensioned or loaded energy storage 3 pulls the moving member 18 in the direction P2, which pushes the ejector 5 in the direction P2 relative to the base plate 2 via the stop member 26 and pushes.

As soon as the ejector 5 moves on the base plate 2 in the direction P2, a pawl component 24 of the ejector unit 1, which is mounted pivotably on the ejector 5, becomes a swiveled-in position that is completely sunk to an outer edge of the base plate 2 FIG. 4 placed in a with a nose partially over the outer edge of the base plate 2 projecting swung-out position ( FIG. 5 ), which is realized via a loop-shaped closed guide track 25 in the base plate 2 and a guide pin 24 a engaging on the pawl component 24.

To illustrate the pawl member 24 whose hidden by other components, in particular by the ejector 5 outline in the FIGS. 3 to 8 indicated by dashed lines.

In the in FIG. 5 illustrated basic state, the energy storage device 3 is in an end position of the discharge state, the energy storage device 3 can not move the ejector 5 in the direction P2.

The ejector 5 is then due to the kinetic energy of the drawer 53, which is due to the previous Auswerfbewegung, and / or moved by a manual movement of the drawer 53 in the opening direction M1 by a user in the direction P2 relative to the base plate 2. This is possible because the pawl component 24 pivoted outwards on the ejector 5 abuts on the driver 23, so that the ejector 5 reaches its end position shifted maximally far in the direction P2 on the base plate 2 in the further movement of the drawer. The pawl member 24 is fully pivoted again upon reaching the end position on the ejector 5, which is predetermined by the interaction of the guide track 25 with the guide pin 24 a engaging therein on the pawl component 24.

If the drawer 53 is moved further in the opening direction M1 after an unloading operation of the energy accumulator 3, the ejector unit 1 separates from the driver 24 and the contact between the driver 23 and the contact portion 21 of the set screw 22 is canceled ( FIG. 6 ).

From the end position described above, which occupies the ejector only briefly, the ejector 5 is urged by spring elements 33 on the base plate 2, for example by a few millimeters in the direction of P1. The spring elements 33 have compared to the coil springs 10, 11 of the energy accumulator 3, a comparatively small force. With the movement of the ejector 5 in the direction P1 by the force of the spring elements 33 is a contact portion 29 of the pawl member 24 in a waiting position of the ejector 5 in direct, backlash-free Contact with a bearing pin 31 of a clamping lever 30 of the coupling device 4 brought ( FIG. 6 ). The bearing pin 31 is arranged at a first end of the clamping lever 30 and can move along a linear guide track 27 and / or a linear guide 63, which is formed on the ejector 5, so long free, in particular within an opening operation of the drawer 53, to the pawl member 24 the bearing pin 31 and / or the clamping lever 30 in direct, play-free contact with the ejector 5 holds.

The waiting position of the ejector 5, which in FIG. 6 is shown, is also a start position of the ejector 5 for a charging of the energy storage device 3 via the coupling device. 4

The coupling device 4 comprises in addition to the clamping lever 30, a guide lever 34 and a connecting element 35. The clamping lever 30 is articulated at a second end via a bearing pin 36 on the guide lever 34. The connecting element 35 is likewise articulated on the guide lever 34 at a second end via a bearing journal 37 which is at a distance from the bearing journal 36 and at its first end via a further bearing journal 38 on the movement element 18. The guide lever 34 is movable at a first end via a bearing pin 39, in particular pivotally arranged on the base plate 2. The bearing pin 39 is preferably received both on the base plate 2 and the cover member 9.

A longitudinal axis A1 of the clamping lever 30, which passes through the bearing pins 31, 36 of the clamping lever 30, has an angle α to a first longitudinal axis A2 of the guide lever 34, which runs through the bearing pins 36, 39.

A longitudinal axis A3 of the connecting element 35, which passes through the bearing pins 37, 38 of the connecting element 35, has an angle β to a second longitudinal axis A4 of the guide lever 34, which passes through the bearing pins 37, 39.

The guide lever 34 of the coupling device 4 comprises at a second end a lever attachment 40. On the lever attachment 40, a locking element 41 and a stop element 42 are formed.

The end position of the discharge state of the energy storage 3 ( FIG. 5 ) is predetermined by a stop of the stop member 42 of the guide lever 34 to a wall portion 47 on a web-like wall 48 of the base plate 2. The wall portion 47 is formed, for example, from an annular portion of a damping element. If the stop element 42 of the guide lever 34 abuts the wall section 47 after a discharge operation of the force accumulator 3, a tensile force in the direction P2 is transmitted from the movement element 18 via the connecting element 35 to the guide lever 34 due to a remaining bias of the spiral springs 10, 11. Due to the rigid design of the coupling device 4 and the abutment of the stop member 42 on the wall portion 47, the moving member 18 is prevented from further movement in the direction P2, the force storage 3 is held with the moving member 18 without play in the end position of the discharge.

In particular, the stop element 42 and / or the wall portion 47 may be designed to be elastic or damping, whereby stop noise can be reduced or prevented.

The guide lever 34 can transmit a force with a translation of the clamping lever 30 on the connecting element 35 during clamping of the energy accumulator 3 due to its configuration.

The gear ratio is formed on the one hand by the ratio of the distance of the bearing pins 39 and 36 to the distance of the bearing pins 39 and 37 on the guide lever 34, on the other hand by the combined circular and linear movement of the clamping lever 30 and / or the connecting element 35 to each other during the charging of the Force accumulator 4.

• Der Lagerzapfen 31 und somit das erste Ende des Spannhebels 30 kann sich aufgrund seiner Lagerung in der Führungsbahn 27 ausschließlich parallel zu einer Bewegungsrichtung des Auswerfers 5 insbesondere parallel zu einer Bewegungsrichtung des bewegbaren Möbelteils 53 bewegen.

The elements of the coupling device 4 can move as follows due to their arrangement on the ejection unit 1:

• The bearing pin 31 and thus the first end of the clamping lever 30 can move due to its storage in the guide track 27 exclusively parallel to a direction of movement of the ejector 5 in particular parallel to a direction of movement of the movable furniture part 53.

The bearing pin 38 and thus the first end of the connecting element 35 can move due to its storage on the carriage-like movement element 18 and thus advantageously in the guide contour 19 exclusively parallel to a direction of movement of the moving member 18 and the ejector 5, in particular parallel to the direction of movement of the movable furniture part 53 ,

The bearing pin 36 and thus the second end of the clamping lever 30 can move due to its storage at the second end of the guide lever 34 exclusively in a circular path about a center of rotation of the bearing pin 39 of the guide lever 34.

The bearing pin 37 of the connecting element 35 and thus the second end of the connecting element 35 can move due to its storage in a central region of the guide lever 34 exclusively in a circular path about a center of rotation of the bearing pin 39 of the guide lever 34.

Due to the above-mentioned embodiment, the coupling device 4 can transmit a force for tensioning the energy accumulator 3 from the ejector 5 via the tension lever 30 and the guide lever 34 to the connecting element 35 and thus the energy accumulator 3, in particular the coupling device 4 suppresses the force exerted by the ejector 5 This means that when loading the force accumulator 3, a user has to apply a lower force on the ejector 5 than he would have to muster if he wanted to load the energy accumulator 3 without a reduction or directly pull the end 17 of the energy accumulator 3 in the direction of P1.

The beginning and the end of the charging of the energy accumulator 3 and the coil springs 10 and 11 are in the FIGS. 6 and 7 illustrated.

The tensioning of the energy accumulator 3 takes place with a movement of the drawer 53 when closing or on a partial path of the closing movement of the drawer 53. The starting position of the ejector unit 1, in which it is prepared for tensioning the energy accumulator 3 and waiting for a closing operation of the drawer, shows FIG. 6 ,

If the drawer 53, for example, closed by a user from the outside, the ejector unit 1 moves towards the driver 23 in the direction of M2. For example, due to the inertia of the drawer 53 relative to the base plate 2, the ejector 5 is moved by striking the driver 23 in the direction of P1.

By the coupling of the ejector 5 via the coupling device 4 with the energy storage device 3 while the moving member 18 of the energy accumulator 3 is also displaced in the direction P1 relative to the base plate 2 and the second end 17 of the coil springs 10, 11 displaced in the direction P1 and thus the coil springs 10th 11 dragged out.

At the end of the tensioning process of the energy accumulator 3, the ejector 5 is in a loading end position, this is in FIG. 7 shown. In the clamping state of the energy accumulator 3, the ejector unit 1 is in a locked state.

In the locked state, the locking element 41 of the coupling device 4 and the locking member 7, which is designed as a flap, determine a Locking state, wherein a discharge movement of the coupling device 4 is blocked by the locking member 7.

The tensioning of the force accumulator 3 is completely completed before, for example, an automatic retraction for force-assisted retraction of the drawer 53 in the fully closed closed position on the furniture body 51 is effective. The automatic retraction is not part of the ejector unit 1 and integrated, for example, in the guide means 52 or the partial or full extension.

After the tensioning of the energy accumulator 3, the ejector 5 is moved relative to the base plate 2 in the direction P1 due to the engagement on the driver 23 due to the further closing movement of the drawer 53. Here, the operative connection between the pawl member 24 of the ejector 5 and the bearing pin 31 of the clamping lever 30 is released. This is done by an interaction of the guide track 25 with the guide pin 24a on the pawl member 24, wherein the pawl member 24 is pivoted away by the guide of the guide pin 24a in the guide track 25 from the bearing pin 31 ( FIG. 8 ). In this state, the ejector 5 is decoupled from the coupling device 4 and so far moved in the direction P1, in particular by a automatic feed until the drawer 53 is completely closed on the furniture body 51 and the ejector 5 on the trigger 6 in the normal position according to FIG. 3 pending.

In the basic position of the ejector unit 1 according to FIG. 3 it is possible for a user to manually pull the drawer 53 in the opening direction M1 without an ejector function or without previously canceling the locking state. In this case, the energy storage 3 of the ejector unit 1 remains unactuated or charged.

In order to eject the drawer 53 with the ejector unit 1 from the position completely pushed in or closed on the furniture body 51, a user must act on the drawer from the outside in the direction of M2 in an oppressive manner. For this purpose, the ejector unit 1 has a so-called touch-latch functionality on, which knows a locked state, which can be unlocked by the closed on the furniture body 51 inserted drawer 53 is moved in the closing direction M2. This closing movement or the inward pushing of the drawer 53 in the direction of M2 takes place until reaching a stop position corresponding to a front gap, which in the closed state of the drawer 53 in particular by a distance between an inside of the drawer front 55 and a front end or the side walls 56 of the furniture body 51 is predetermined. The front gap is usually a few millimeters, for example, about 1 to 10 millimeters.

Accordingly, the unlocking of the ejector unit 1 is tuned such that a closing movement of the drawer 53 in the direction of M2 of a few millimeters or at most by the amount of the front gap is sufficient to specify the unlocking and thus the power assisted ejection of the drawer 53 safe.

Starting from the basic position according to FIG. 3 the ejector unit 1 is moved with the drawer 53 in the direction M2. Since the set screw 22 is present on the driver 23, the ejector 5 is moved relative to the base plate 2 in the direction P1, whereby a contact portion 44 presses on the ejector 5 against the trigger 6 and pushes it in the direction P1 accordingly. The trigger 6 is limited linearly in the direction of P1 and P2 slidably provided on the base plate 2, usually by a few millimeters or less than the dimension of the front gap.

The trigger 6 is preferably coupled directly to the locking member 7, which is designed as a flap 43, such that the linear release movement of the trigger 6 in the direction P1, the flap 43 in a rotational movement about a pivot axis D is added. By the rotational movement, the flap 43 is released from a locking position, in which the flap 43 is urged by a trained as a leaf spring 49 spring member. In the locked state of the ejector unit 1, the flap 43, which is in the locked position, blocks the guide lever 34 or the lever attachment 40 such that the energy storage device 3 remains in its charged state.

With the rotational movement of the flap 43, the blockage of the guide lever 34 is released. Preferably, the prestressed with a leg spring 60 locking element 41 pivots on the lever cap 40 from.

The protruding on the lever cap 40 locking element 41 moves with the pivoting operation of the guide lever 34 below the flap 43 of this past and leads initiated by the trigger 6 rotational movement of the flap 43 about the pivot axis D without interruption. As a result, a rotational angle of the flap 43 is advantageously increased from the locking position. By the movement of the lever cap 40 under the flap 43 over and continued by the swinging out locking element 41, the ejector unit 1 is unlocked safely. For this purpose, a comparatively very small linear release movement of the trigger 6 in the direction P1 is advantageously necessary. By the leaf spring 49, the cap 43 is then pushed back into its locked position.

When tensioning the energy accumulator 3 comes that, swung out on the lever cap 40, existing locking element 41 again in abutment with a front edge of the flap 43. The locking element 41 deviates against the spring force of the leg spring 60 back so that it so far on an edge of the lever cap 40th sunk that the guide lever 34 can pivot past the flap 43 with the lever cap 40.

Behind the flap 43, the locking element 41 is swung out again by the spring force of the leg spring 60. After the clamping operation, the guide lever 34 is pressed with the protruding locking element 41 against the locking spring 43 held by the leaf spring 49, whereby the energy accumulator 3 is in the locked state.

The rotational movement of the flap 43 of the ejector unit 1 or the device 58 is transmitted via a synchronous rod 61, which is arranged non-rotatably on the flap 43, on a second advantageous equivalent device 62, which is arranged on the drawer 53.

Advantageously, the synchronizing rod 61 connects the locking member 7 with a second locking member provided on the second device 62. The two locking members are thus motion-coupled directly and / or synchronously. This represents a contrary principle of synchronization to a connection between trigger elements of two ejector devices on a furniture part. <U> REFERENCE LIST: </ u> 1 ejector 33 spring element 2 baseplate 34 guide lever 3 power storage 35 connecting element 4 coupling device 36 pivot 5 ejector 37 pivot 6 trigger 38 pivot 7 locking member 39 pivot 8th Front gap setting arrangement 40 Lifting run rate 41 locking element 9 cover member 42 stop element 10 spiral spring 43 flap 11 spiral spring 44 Contact section 12 The End 45 casing 13 fixed bearing 46 operating section 14 bearing part 47 wall section 15 adjusting part 48 wall 16 operating section 49 leaf spring 17 The End 50 Furniture 18 mover 51 furniture body 19 guide contour 52 guide means 20 linear guide 53 drawer 21 Contact section 54 drawer base 22 screw 55 drawer front 23 takeaway 56 Side wall 24 latch member 57 Drawer rear wall 24a spigot 58 contraption 25 guideway 59 Body side wall 26 stop element 60 Leg spring 27 guideway 61 synchronous rod 28 - 62 contraption 29 contact section 63 linear guide 30 clamping lever 31 pivot 32 holding member
