Description

The invention relates to a device for moving a movable furniture part according to the preamble of claim 1 and a piece of furniture with a device for moving a movable furniture part.

State of the art

Various embodiments of a device for moving a movable furniture part in relation to a furniture carcass of a piece of furniture are known from the prior art, in which the movable furniture part can be brought via guide means in an opening direction and in a closing direction opposite to the opening direction, the apparatus having a force accumulator , Under the effect of the energy storage, it is possible to eject the movable furniture part in the opening direction via an ejector, that is to bring in an open position.

A charge of the energy storage can be done when fully open as well as when closing the movable furniture part with respect to a furniture body.

Purpose and advantages of the invention

The invention has for its object to provide a device for moving a movable furniture part or a furniture in which a loading process of an energy storage is improved.

This object is solved by the features of claims 1 and 10, respectively.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention relates to a device for moving a movable furniture part in an opening direction with respect to a furniture carcass of a piece of furniture, wherein the movable furniture part can be brought via guide means in the opening direction and in a direction opposite to the opening direction closing direction and wherein the device has a force accumulator, so with the mounted on the furniture device, the movable furniture part can be brought in an opening operation under the action of the energy storage via an ejector in an open position.

The essence of the invention lies in the fact that a coupling arrangement is provided which is effective during the charging process of the energy storage between ejector and energy storage, and that the ejector is configured in such a way that it in the region of the end of a path during the opening process with the coupling arrangement over a switching element couples.

By this measure it can be achieved that the ejector via a charging process of the energy storage device in a closing movement of the movable furniture part after opening the movable furniture part on the coupling arrangement with the energy storage device for a preferred power transmission from Ejector is in operative connection with the energy accumulator.

By way of example, a force amplification of a charging force acting on the ejector on the force accumulator can be achieved via the coupling arrangement, for example by reinforcement via a lever arrangement effective in the coupling arrangement.

On the other hand, for example, the ejector may be in direct contact with the force accumulator for an opening operation of the movable furniture part, with a coupling arrangement which is not effective during this phase. That is, the energy storage then acts directly without the interposed coupling arrangement and thus without a power reduction, which would then be effective in this direction. Rather, the force is transmitted directly from the energy storage on the movable furniture part, in particular via the ejector.

For example, the coupling arrangement comprises a plurality of levers which are in operative connection with each other. The movable furniture part may be, for example, a drawer or a cabinet door.

In a further preferred embodiment of the invention, the switching element is formed on the ejector in a manner with respect to the device, that the ejector can be brought into operative connection with the coupling arrangement for a charging operation of the energy accumulator when a driver to the ejector occupies a predetermined position.

For example, the ejector with the coupling assembly can be brought into operative connection when a driver of the guide means on the furniture body or on the movable furniture part or directly attached to the furniture body driver leaves the ejector during the opening process.

Advantageously, the switching element is so on the ejector formed so that it interacts with the driver so that when a movement in the opening direction of the ejector is taken from the driver.

Conveniently, the switching element is further designed in such a way on the ejector that the switching element can couple only in an opening movement of the movable furniture part with the driver.

It is also conceivable that the switching element is arranged on the coupling arrangement.

It is also advantageous if the ejector occupies a locking position with the coupling arrangement when the ejector returns from an end position during the opening process into a waiting position in the closing direction.

For example, 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 energy accumulator via the coupling arrangement, in particular when the ejector comes into contact with the driver.

The waiting position can reach the ejector, for example, when the driver leaves the ejector, which can be realized by a corresponding positioning of the switching element, for example via a slotted guide and then travels a predetermined distance, in particular a few mm, in the closing direction until the switching element in operative contact comes with the coupling arrangement.

In a further advantageous embodiment of the invention, the ejector is in the waiting position under a bias.

The ejector may be pressure loaded in the waiting position.

Advantageously, there is the complete Coupling arrangement in the waiting position under a bias, in particular, is a coupling member, for example, a lever under a pressure-loaded bias.

In addition, it is preferred if the ejector is coupled to the coupling arrangement for a charging operation such that a pressure force is transmitted from the ejector to the coupling arrangement.

In this way, the entire system of ejector, coupling assembly and force accumulator in one of e.g. slightly pressurized standby position for charging the force accumulator so that without any "empty motion" the system can apply force to the driver directly to the force accumulator, for example, clacking sounds or other noises that occur when a "loose" system is rapidly biased, be avoided.

Moreover, it is preferred if the switching element has a hook portion which serves as a stop for a driver in order to be able to move the ejector during the opening operation in an end position.

This measure ensures a clear positioning of the ejector. He can preferably only be released from a driver when the ejector has reached an end position.

In this state, the hook portion, with which the driver is based, is favorably moved away, so that the driver can disengage from the ejector.

The corresponding positioning of the switching element with, in particular, hook section on the ejector can be achieved, for example, by moving the switching element along a guide track, for example a guide track. Thereby, the position of the switching element with respect to Ejector in particular positively controlled, that is, a predetermined position of the ejector results in a predetermined position of the switching element on the ejector.

It is also preferred if the switching element is pivotally mounted on the ejector.

Through this procedure, the switching element can be brought by a simple pivoting movement out of engagement with a driver or in engagement with the driver.

On the other hand, the switching element in a pivot position, a coupling of the coupling arrangement with the ejector ensure, for example, when the ejector returns from its end position during the opening operation in a waiting position in the closing direction.

In this case, the switching element pivots advantageously so that a certain return path of the ejector is allowed, but then the ejector goes through the appropriately positioned switching element on an element of the coupling arrangement in conditioning and further movement is only possible by charging the force accumulator, for example by tensioning springs in the energy storage.

In a preferred embodiment of the invention, the switching element is a latch element. A pawl element can be easily pivoted, in particular arrange on the ejector and control accordingly in position. For controlling the switching element is also proposed that the switching element is guided in a movement of the ejector via guide means on a base part.

For example, the switching element, in particular the pawl element is guided over a gate during a movement of the ejector in a predetermined desired position or transferred into this. The backdrop is preferably formed on the base part.

Moreover, it is favorable if the guide means comprise a closed path.

By this measure can be forcibly controlled in a "reciprocating motion" of the ejector unfolding and folding of the switching element, in particular of the pawl member so that the pawl element occupies a desired predetermined position in each movement position of the ejector, wherein the positioning after a completed, for example, linear reciprocating motion, preferably in a direction of circulation on the track repeated.

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, two opposite 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 element designed as 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. Figures 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 is provided with a stop member 26 which is in Auswerfvorgang the furniture part with an ejector 5 in contact.

The ejector 5 is in particular exclusively linearly movable or parallel to the direction of movement of the drawer 5, preferably exclusively during the closing operation of the drawer 53, via the coupling device 4 Movement member 18 in the directions P1 and P2 back and forth 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, the stop element 26 is formed on the movement element 18, which advantageously has an elastic design and thus prevents or at least dampens a disturbing noise for a user when the movement element 18 strikes the ejector 5 in the opening operation of the drawer 53. 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, 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 is predetermined.

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 on Furniture body 51 may be mounted 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 preceding ejection movement is, 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 a discharge process of the energy accumulator 3, the ejector unit 1 separates from the driver 23 and in particular 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, a contact portion 29 of the latch member 24 in a waiting position of the ejector 5 in direct, play-free contact with a bearing pin 31 of a clamping lever 30 of the coupling device 4 is 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 by a stop of the stop member 42 of the guide lever 34 to a wall portion 47 at a web-like wall 48 of the base plate 2 predetermined. 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 may be due to its storage in the guideway 27 exclusively parallel to a direction of movement of Ejectors 5 in particular move 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 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 less force to the ejector 5 than he would have to apply if he wanted to load the energy accumulator 3 without a reduction or directly the end 17 of the energy accumulator 3 in Would draw direction 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 configured 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 energy accumulator 3 is completely completed before, for example, an automatic retraction for power 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 which knows a locked state which can be unlocked by moving the inserted drawer 53 closed on the furniture body 51 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 according to a front gap, which is predetermined 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 side or the side walls 56 of the furniture body 51. 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 locking position, blocks the guide lever 34 or the lever cap 40 such that the energy accumulator 3 remains in its charged state.

With the rotation of the flap 43, the blockade of Guide lever 34 repealed. 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 via a synchronous rod 61 which is rotatably mounted on the flap 43, on a second advantageous equivalent device 62, which on the drawer 53rd is arranged, transferred.

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.
