The DE 20 2005 002 433 U discloses such a device

Object and advantages of the invention

The invention is based on the object of providing a device of the type described in the introduction which comprises an improved device for adjusting the front gap.

This object is achieved by the features of claim 1.

Advantageous and expedient embodiments of the invention are specified in the dependent claims.

The invention is based on a device for moving a movable furniture part in an opening direction in relation to a furniture body of a piece of furniture, the movable furniture part being able to be brought via guide means in the opening direction and in a closing direction opposite to the opening direction. The device has an energy storage device, with the device mounted on the furniture unit being able to bring the movable furniture part into the opening direction when the movable furniture part is opened under the action of the energy storage mechanism, and the energy storage mechanism is charged when the movable furniture part is moved in the closing direction. A front gap is formed on the furniture between the movable furniture part and the furniture body in a closed state of the movable furniture part, the front gap being adjustable via an adjustment arrangement, the movable furniture part being able to move from the closed state into a movement in the closing direction and the length of movement of the movable furniture part is designed in the closing direction such that the loaded energy storage device is unlocked.

The movable furniture part is preferably designed as a drawer or flap and the drawer or flap is movably guided on the furniture body via guide means, for example pull-out rails or hinges, on the furniture body.

The device is advantageously arranged on the movable furniture part, in particular on an underside of a drawer bottom. However, the device can also be attached to the guide means of the furniture part and / or to the furniture body.

The adjustment arrangement can be designed to discretely and / or continuously adjust the front gap between the movable furniture part and the furniture body in the opening direction.

The adjustment arrangement can consist of metal, for example steel and / or sheet metal, plastic, wood or a combination of the materials.

It is conceivable that the setting arrangement is designed independently of other elements, such as an ejector or a trigger of the energy store of the device according to the invention on the furniture and / or on the movable furniture part and / or on the guide means of the furniture part.

In an advantageous embodiment of the invention, the adjustment length of the adjustment arrangement is proportional, preferably linearly proportional to the adjustment length of the front gap.

The essential aspect of the invention can now be seen in the fact that the adjustment arrangement comprises an elastic member.

According to the invention, the elastic organ is designed to be elastically deformable. The elastic member is advantageously designed to be resilient and / or to absorb noise.

For example, when an ejector comes into contact with a driver of the movable furniture part and / or the guide means of the furniture part and / or of the furniture body Opening and / or closing process of the movable furniture part, a clacking noise can be avoided or at least reduced.

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

For example, the elastic organ is made from plastic, in particular from rubber and / or metal and / or wood and / or a combination of the materials.

For example, the attachment section provides several attachment positions and the attachment positions are designed in such a way that they can advantageously be used in a grid in the closing and / or opening direction of the movable furniture part.

The adjustment arrangement can, for example, be clipped and / or clamped and / or screwed to an attachment position of the attachment section in a comparatively simple manner, for example in the manner of a bayonet. As a result, a comparatively simple step-by-step adjustment of the front gap is advantageously possible over a comparatively large length range.

The setting arrangement is advantageously arranged on an ejector in such a way that the setting arrangement is moved along with a movement of the movable furniture part and / or the ejector.

It is also advantageous that an actuating element of the setting arrangement is designed to be self-locking.

The adjusting element can be designed on the housing of the adjustment arrangement in such a way that the front gap of the furniture can be adjusted by means of a particularly continuous change in position of the adjusting element on the housing of the adjustment arrangement.

If the actuating element is designed to be self-locking, the actuating element can automatically remain in a set position on the housing of the setting arrangement, for example.

The adjusting element can advantageously be designed in such a way that the length of the adjusting element can be changed. For example, the adjusting element consists of two parts and a first part of the adjusting element is fixedly arranged on the adjusting arrangement and a second part of the adjusting element is designed to be movable relative to the first part of the adjusting element. This also makes it possible to adjust the front gap of the piece of furniture, in particular continuously, in a comparatively small length range.

It is also conceivable that the adjustment arrangement on the housing differently designed adjusting elements can be arranged.

It is also conceivable that the housing of the adjustment arrangement is designed in such a way that adjusting elements of different lengths can be arranged on the housing of the adjustment arrangement.

In a modification of the invention, the adjustment arrangement comprises an elastic stop element, the elastic stop element being designed on the adjustment arrangement in such a way that it can interact with a driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body.

For example, the elastic stop member is formed on the actuating element of the setting arrangement, in particular it is formed on the actuating element in such a way that it acts between the actuating element and a driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body.

According to the invention, the elastic stop member is designed to be elastically deformable. It is also conceivable that the elastic stop member is designed to be resilient and / or noise-absorbing. As a result, a noise that is annoying for a user, for example a click, at the moment of contact with the driver during an opening and / or closing process of the movable furniture part can be avoided and / or reduced.

In particular, the adjustment arrangement has two elastic stop members.

A first elastic stop element can be formed on the adjusting element of the setting arrangement and a second elastic stop element can be formed on the housing of the setting arrangement be arranged.

The first elastic stop member on the actuating element can be designed to interact with a driver, which is formed, for example, on guide means of the furniture part and / or on the furniture body and / or the movable furniture part. The second elastic stop member can be arranged on the housing of the adjustment arrangement and interact with a contact element of the trigger of the energy store of the device.

It is further proposed that the housing of the adjustment arrangement comprises a stop element, the stop element being designed such that a minimum and / or maximum position of the actuating element of the adjustment arrangement on the housing of the adjustment arrangement is specified.

In a further preferred embodiment of the invention, the minimum position of the adjusting element on the housing of the adjustment arrangement corresponds to a minimum adjustable front gap and the maximum position of the adjusting element on the housing of the adjustment arrangement corresponds to a maximum adjustable front gap between the movable furniture part and the furniture body in the opening direction.

In addition, it is advantageous that the adjustment arrangement is arranged on the movable furniture part.

It is conceivable that the adjustment arrangement is arranged on a surface facing the interior of the furniture, in particular on the inside of a front wall of a drawer, of the movable furniture part.

In a further advantageous embodiment of the invention, the adjustment arrangement, which is arranged on the movable furniture part, interacts with an in particular elastic stop member on an end face of a furniture body.

The adjustment arrangement is preferably designed on the movable furniture part in such a way that the adjustment arrangement interacts with an elastic stop member of a driver of the guide means of the furniture part and / or of the furniture body. For example, the setting arrangement is formed on the device which is arranged on the movable furniture part.

It is also advantageous that the setting arrangement is arranged on a trigger of the device.

If the setting arrangement is arranged on the trigger of the device, it is conceivable that the trigger comprises the housing of the setting arrangement.

The setting arrangement is advantageously arranged on the trigger in such a way that it can interact with a driver of the movable furniture part and / or the guide means of the furniture part and / or the furniture body.

It is also conceivable that the setting arrangement is arranged on the trigger and the trigger interacts via the setting arrangement with an ejector of the device and / or a driver in such a way that when the movable furniture part is moved out of the closed state on the furniture part in the closing direction, the loaded energy store is unlocked .

In an advantageous modification of the invention, the adjustment arrangement is arranged on guide means of the furniture, the adjustment arrangement can be arranged on an attachment section of the guide means of the furniture part.

The adjustment arrangement is advantageously arranged on a central rail, in particular on a body rail for a drawer on the furniture part, on an attachment section.

For example, the attachment section of the guide means comprises several attachment positions and the attachment positions are designed such that they can be used in a grid in the closing and / or opening direction of the movable furniture part. In this way, the front gap can advantageously be set in particular discretely.

If the adjustment arrangement is arranged, for example, on the guide means of the furniture and the device is arranged, for example, on the movable furniture part, the adjustment arrangement is designed as a driver or is formed on a driver. In particular, the setting arrangement acts as a driver by means of an elastic stop member on an ejector of the device in such a way that the loaded energy store is unlocked when the movable furniture part is moved from the closed state on the furniture part in the closing direction.

The adjustment arrangement is advantageously arranged in a fixed position on the furniture body.

In an advantageous embodiment of the device, the setting arrangement is arranged on an end face of the furniture body, wherein the end face of the furniture body can be at least partially covered by the movable furniture part in the closed state of the movable furniture part.

A piece of furniture 50 according to the invention with a box-shaped furniture body 51 and a drawer 53 guided movably via guide means 52 is shown in FIG Figure 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 guide means 52 with the same effect are provided between each side wall 56 of the drawer 53 and an associated body side wall 59. 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 on an underside of the drawer bottom 54.

Figure 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 force-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 53.

The drawer 53 is mounted on the furniture body 51 so as to be displaceable in the direction of M1 and M2 via the guide means 52, for example two similar partial or full pull-outs. The ejector unit 1 can alternatively be arranged on the furniture body 51 or on the guide means 52 of the furniture 50.

The ejector unit 1 includes, inter alia, a base plate 2, an energy store 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 Figure 9 can be seen. The ejector unit 1 can be arranged over the housing or over 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.

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

According to the exemplary embodiment shown, the energy store 3 comprises two parallel-arranged spiral springs 10, 11 of the same type, which form a spring assembly. At a first end 12 of the energy store 3, the spiral springs 10, 11 are arranged on an adjustable fixed bearing 13. The fixed bearing 13 comprises a movable bearing part 14, on which the spiral springs 10, 11 are detachably but firmly received, and an actuating part 15 with an operating section 16 via which a user can adjust a position of the end 12 of the energy storage mechanism 3 in a changeable manner from the outside. In this way, a force action of the energy store 3 on the drawer 53 during the opening process of the drawer 53 can advantageously be preset.

At a second end 17 of the energy store 3, the associated ends of the spiral springs 10, 11 are attached to a slide-like movement element 18. The slide-like movement element 18 can be moved into a corresponding guide contour 19 on the base plate 2 Direction of movement P1 and an opposite direction of movement P2 linearly guided.

The directions of movement P1 and P2 of the movement element 18 (see Sect. 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 arranged in a fixed position 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 corresponds to the direction P2.

In the following, an assembly state of the ejector unit 1 on the drawer bottom 54 is assumed.

The Figures 3 , 7th , 8th show the ejector unit 1 in a tensioned state of the energy storage device 3, in which the spiral springs 10, 11 are elongated or tensioned under tension, here the movement element 18 is offset in relation to a retracted position on the base plate 2 in the direction P1 and in a Clamping position held.
The Figures 5 , 6th show the ejector unit 1 in a discharged basic state of the energy store 3, in which the spiral springs 10, 11 are still tensioned, but with a smaller amount, and have a length L1.

In the tensioned state of the energy store 3, the spiral springs 10, 11 have a length L2 which is greater than L1.

A holding member 32 with a stop element 26 is provided on the movement element 18. The stop element 26 is in contact with an ejector 5 during a force-assisted opening process.

Via the coupling device 4, the energy store 3 or the movement element 18 is preferably only in operative connection with the ejector 5 during the closing process of the drawer 53. The ejector 5 is in particular exclusively linearly movable or parallel to the direction of movement of the movement element 18 in the directions P1 and P2 - and can be moved here. For this purpose, a linear guide 20 is formed on the base plate 2, which z. B. is matched on one side of the ejector 5.

An opening process of the drawer 53 brought about by the ejector unit 1 takes place exclusively via a direct operative connection of the energy store 3 via the movement element 18 moving in the direction P2 to the ejector 5. For this purpose, the stop element 26 is formed on the movement element 18, which is advantageously designed to be elastic and thus prevents or at least dampens a noise that is annoying to a user when the movement element 18 hits the ejector 5 during the opening process of the drawer 53 ( Figure 3 , 4th , 5 ).

A front gap setting arrangement 8 comprises a housing 45 and an adjusting screw 22 with a contact section 21. In addition, a cuboid opening 72 is formed on the housing 45. Due to the opening 72, four inner walls are formed in the interior of the housing 45, two opposing inner walls being designed as stops 69, 70 for an annular stop element 66 of the adjusting screw 22.

The housing 45 of the front gap setting arrangement 8 is formed on the ejector 5 on the attachment section 65 and is clamped or clipped onto the cover component 9 by means of an elastic member 67, which is nose-shaped, and movably guided on a guide section 68 on the cover component 9.

The adjusting screw 22 has an external thread 64 which cooperates with an internal thread on the housing 45 of the front gap adjustment arrangement 8. By intuitive, simple, manual rotation of an operating section 46 of the adjusting screw 22 by a user, depending on the direction of rotation of the adjusting screw 22, a position of the contact section 21 of the adjusting screw 22 can be adjusted in the direction P1 or P2. The adjusting screw 22 is designed, in particular, to be self-locking relative to the housing 45 of the front gap setting arrangement 8. By specifying the position of the adjusting screw 22, a dimension of a front gap between the drawer front 55 of the drawer 53 closed on the furniture body 51 and the end faces of the furniture body 51 can be specified ( Figure 10 , 11 ).

After the adjusting screw 22 has been inserted into the housing 45 of the front gap adjustment arrangement 8, the annular stop element 66, which is designed as a locking ring, is in the opening 72 on the adjusting screw 22, onto which the adjusting screw 22 is clamped or clipped. A minimum or maximum position of the adjusting screw 22 on the housing 45 of the front gap adjustment arrangement 8 can be predetermined by the stop element 66. The position can then be specified when, by a user in particular continuously adjusting the adjusting screw 22 in the direction P1 or P2, the stop element 66 is in contact with stops 69, 70 on the housing 45 of the front gap setting arrangement 8.

Furthermore, the adjusting screw 22 comprises a guide pin 71. The adjusting screw 22 is adjustably guided with the guide pin 71 in a bore on the housing 45 of the front gap adjustment arrangement 8.

In the tensioned or charged state of the energy storage mechanism 3, the contact section 21 of the adjusting screw 22 rests against a driver 23, which, in corresponding operating states, acts as a stop for the contact section 21 forms. The one in the Figures 3 to 8 Driver 23 indicated only by dashed lines can be present, for example, on a fixed rail of the guide means 52 or attached to the furniture body 51 if the ejector unit 1 is arranged on the drawer 53.

If, on the other hand, the ejector unit 1 is arranged on the furniture body 51 or on a fixed part of the guide means 52 of the furniture 50, the driver 23 can be provided on the drawer 53 and thus movable relative to the furniture body 51.

Starting from the basic position of the ejector unit 1 according to Figure 3 a lock on the ejector unit 1 lifted what Figure 4 and is explained in more detail below, the tensioned or charged energy store 3 pulls the movement element 18 in the direction P2, which pushes or pushes the ejector 5 in the direction P2 relative to the base plate 2 via the stop element 26.

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 pivotably mounted on the ejector 5, is moved from a pivoted position that is completely sunk to an outer edge of the base plate 2 Figure 4 brought into a pivoted position with a nose partially protruding over the outer edge of the base plate 2 ( Figure 5 ), which is implemented on the pawl component 24 via a loop-shaped closed guide track 25 in the base plate 2 and a guide pin 24a engaging therein.

To illustrate the pawl component 24, its outline, which is covered by other components, in particular by the ejector 5, is shown in FIG Figures 3 to 8 indicated by dashed lines.

In the in Figure 5 The basic state shown is the energy storage device 3 in an end position of the unloaded state, whereby the energy store 3 cannot move the ejector 5 any further in the direction P2.

The ejector 5 is then displaced relative to the base plate 2 in the direction P2 due to the kinetic energy of the drawer 53, which is due to the previous ejecting movement, and / or by a manual further movement of the drawer 53 in the opening direction M1 by a user. This is possible because the pawl component 24 pivoted out above on the ejector 5 abuts the driver 23, so that in the further course of movement of the drawer the ejector 5 reaches its end position, which is displaced as far as possible in the direction P2 on the base plate 2. The pawl component 24 is completely swiveled in again when the end position on the ejector 5 is reached, which is predetermined by the interaction of the guide track 25 with the guide pin 24a engaging therein on the pawl component 24.

If the drawer 53 is moved further in the opening direction M1 after the energy store 3 has been unloaded, the ejector unit 1 separates from the driver 24 and the contact between the driver 23 and the contact section 21 of the adjusting screw 22 is canceled ( Figure 6 ).

From the end position described above, which the ejector assumes only for a short time, the ejector 5 is urged by spring elements 33 on the base plate 2, for example by a few millimeters in the direction P1. The spring elements 33 have a comparatively low force compared to the spiral springs 10, 11 of the energy accumulator 3. With the movement of the ejector 5 in the direction P1 by the force of the spring elements 33, a contact section 29 of the pawl component 24 is brought into direct, play-free contact with a bearing pin 31 of a tensioning lever 30 of the coupling device 4 in a waiting position of the ejector 5 ( Figure 6 ). The bearing pin 31 is arranged at a first end of the tensioning lever 30 and can extend along a, for example, linear guide track 27 and / or a linear guide 63, which is formed on the ejector 5, move freely, in particular within an opening process of the drawer 53, until the latch component 24 holds the bearing pin 31 and / or the clamping lever 30 in direct, play-free contact with the ejector 5.

The waiting position of the ejector 5, which is shown in Figure 6 is shown, is also at the same time a start position of the ejector 5 for a charging process of the energy store 3 via the coupling device 4.

In addition to the tensioning lever 30, the coupling device 4 comprises a guide lever 34 and a connecting element 35. The tensioning lever 30 is articulated at a second end via a bearing pin 36 on the guide lever 34. The connecting element 35 is articulated at a second end via a bearing journal 37 spaced apart from the bearing journal 36 to the guide lever 34 and at its first end via a further bearing journal 38 to the movement element 18. The guide lever 34 can be moved at a first end via a bearing pin 39, in particular is arranged pivotably on the base plate 2. The bearing pin 39 is preferably received both on the base plate 2 and on the cover component 9.

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

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

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

The end position of the unloading state of the energy store 3 ( Figure 5 ) is specified by a stop of the stop element 42 of the guide lever 34 on a wall section 47 on a web-like wall 48 of the base plate 2. The wall section 47 is formed, for example, from an annular section of a damping element. If the stop element 42 of the guide lever 34 is on the wall section 47 after the energy storage device 3 has been discharged, 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 stiff design of the coupling device 4 or the abutment of the stop element 42 on the wall section 47, the movement element 18 is prevented from further movement in the direction P2, the energy accumulator 3 with the movement element 18 being held in the end position of the unloaded state without play.

In particular, the stop element 42 and / or the wall section 47 can be designed to be elastic or damping, so that the stop noise is reduced or prevented.

Due to its design, the guide lever 34 can transmit a force with a translation from the tensioning lever 30 to the connecting element 35 when the energy store 3 is tensioned.

The transmission ratio is formed on the one hand by the ratio of the distance between the bearing pins 39 and 36 to the distance between 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 loading process Lift mechanism 4.

Due to their arrangement on the ejector unit 1, the elements of the coupling device 4 can move as follows:
The bearing pin 31 and thus the first end of the tensioning lever 30 can move 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, due to its mounting in the guide track 27.

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

The bearing pin 36 and thus the second end of the tensioning lever 30 can only move in a circular path around a center of rotation of the bearing pin 39 of the guide lever 34 due to its mounting on the second end 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 exclusively in a circular path around a center of rotation of the bearing pin 39 of the guide lever 34 due to its mounting in a central region of the guide lever 34.

Due to the design mentioned above, the coupling device 4 can transmit a force for tensioning the energy store 3 from the ejector 5 via the clamping lever 30 and the guide lever 34 to the connecting element 35 and thus the energy store 3, in particular the coupling device 4 reduces the force exerted by the ejector 5 on the energy storage device 3. This means that when the energy storage device 3 is being charged, a user on the ejector 5 has less Has to apply force than he would have to apply if he wanted to load the energy storage device 3 without a reduction or would pull the end 17 of the energy storage device 3 directly in the direction P1.

The beginning and the end of the loading process of the energy store 3 and the coil springs 10 and 11 are in the Figures 6 and 7th illustrated.

The energy storage mechanism 3 is tensioned with a movement of the drawer 53 when it is closed or on a part 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 storage mechanism 3 and is waiting for the drawer to close, is shown Figure 6 .

If the drawer 53 is closed from the outside, for example by a user, the ejector unit 1 moves in the direction M2 towards the driver 23. When the contact section 21 of the adjusting screw 22 of the ejector 5 hits the driver 23, the loading process of the energy store 3 begins. For example, due to the inertia of the drawer 53 relative to the base plate 2, the ejector 5 is moved in the direction P1 by striking the driver 23.

By coupling the ejector 5 to the energy store 3 via the coupling device 4, the movement element 18 of the energy store 3 is also displaced in the direction P1 relative to the base plate 2 and the second end 17 of the spiral springs 10, 11 is displaced in the direction P1 and thus the spiral springs 10 , 11 elongated.

At the end of the tensioning process of the energy store 3, the ejector 5 is in a loading end position, this is in FIG Figure 7 shown. In the tensioned state of the energy store 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 element 7, which is designed as a flap, determine a locking state, an unloading movement of the coupling device 4 being blocked by the locking element 7.

The tensioning of the energy store 3 is completely completed before, for example, an automatic retraction mechanism for power-assisted retraction of the drawer 53 into the fully closed position on the furniture body 51 becomes effective. The automatic feed mechanism is not part of the ejector unit 1 and is integrated, for example, in the guide means 52 or the partial or full extensions.

After the energy storage mechanism 3 has been tensioned, the further closing movement of the drawer 53 moves the ejector 5 in the direction P1 relative to the base plate 2 due to the contact with the driver 23. Here, the operative connection between the pawl component 24 of the ejector 5 and the bearing pin 31 of the clamping lever 30 is canceled. This is done by the interaction of the guide track 25 with the guide pin 24a on the pawl component 24, the pawl component 24 being pivoted away from the bearing pin 31 by the guidance of the guide pin 24a in the guide track 25 ( Figure 8 ). In this state, the ejector 5 is decoupled from the coupling device 4 and can be moved in the direction P1, in particular by means of an automatic retraction system, until the drawer 53 is completely closed on the furniture body 51 and the ejector 5 on the trigger 6 is in the basic position according to FIG Figure 3 pending.

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

In order to eject the drawer 53 with the ejector unit 1 from the completely pushed in or closed position on the furniture body 51, a user has to exert a pressure on the drawer from the outside in the direction M2. For this purpose, the ejector unit 1 has what is known as a touch-latch functionality, which has a locked state that can be unlocked by moving the pushed-in 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 direction M2 takes place until it reaches a stop position corresponding to a front gap, which in the closed state of the drawer 53 is in particular due to 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 specified. The front gap is usually a few millimeters, for example approx. 1 to 10 millimeters.

Accordingly, the unlocking of the ejector unit 1 is coordinated in such a way that a closing movement of the drawer 53 in the direction M2 of a few millimeters or a maximum of the amount of the front gap is sufficient to reliably predetermine the unlocking and thus the force-assisted ejection of the drawer 53.

Starting from the basic position according to Figure 3 the ejector unit 1 with the drawer 53 is moved in the direction M2. Since the adjusting screw 22 rests on the driver 23, the ejector 5 is moved relative to the base plate 2 in the direction P1, whereby a contact section 44 on the ejector 5 presses against the trigger 6 and pushes it accordingly in the direction P1. The trigger 6 is provided on the base plate 2 and is linearly displaceable to a limited extent in the direction P1 and P2, generally by a few millimeters or less than the size of the front gap.

The trigger 6 is preferably directly coupled to the locking member 7, which is designed as a flap 43, in such a way that the linear triggering movement of the Trigger 6 in the direction P1, the flap 43 is displaced in a rotary movement about a pivot axis D. As a result of the rotary movement, the flap 43 is released from a locking position into which the flap 43 is urged by a spring element designed as a leaf spring 49. 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 attachment 40 in such a way that the energy store 3 remains in its charged state.

With the rotary movement of the flap 43, the blockage of the guide lever 34 is released. The locking element 41 on the lever attachment 40, which is pretensioned by a leg spring 60, preferably swivels out.

The locking element 41 protruding from the lever attachment 40 moves with the pivoting process of the guide lever 34 below the flap 43 past the latter and continues the rotary movement of the flap 43 about the pivot axis D initiated by the trigger 6 without interruption. As a result, an angle of rotation of the flap 43 from the locking position is advantageously increased. By moving the lever attachment 40 under the flap 43 and continued by the pivoting locking element 41, the ejector unit 1 is safely unlocked. For this purpose, a comparatively very small linear triggering movement of the trigger 6 in the direction P1 is advantageously necessary. The leaf spring 49 then pushes the cap 43 back into its locking position.

When the energy store 3 is tensioned, the locking element 41, swiveled out on the lever attachment 40, again comes into contact with a front edge of the flap 43. The locking element 41 moves back against the spring force of the leg spring 60, so that it is so far on one edge of the lever attachment 40 is sunk so that the guide lever 34 with the lever attachment 40 can pivot past the flap 43. Behind the flap 43, the locking element 41 is pivoted out again by the spring force of the leg spring 60. After the tensioning process, the guide lever 34 with the protruding locking element 41 is pressed against the flap 43 held in a locking manner by the leaf spring 49, with the result that the energy store 3 is in the locked state.

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

The synchronizing rod 61 advantageously connects the locking element 7 to a second locking element present on the second device 62. The two locking members are thus directly and / or synchronously coupled in terms of movement. This represents a contrary principle of synchronization to a connection between the release elements of two ejector devices on a piece of furniture. <u> List of reference symbols: </u> 1 Ejector unit 34 Guide lever 2 Base plate 35 Connecting element 3 Energy storage 36 Journal 4th Coupling device 37 Journal 5 Ejector 38 Journal 6th trigger 39 Journal 7th Locking device 40 Lever attachment 8th Front gap adjustment assembly 41 Locking element 42 Stop element 9 Cover component 43 flap 10 Coil spring 44 Contact section 11 Coil spring 45 casing 12th end 46 Operating section 13th Fixed bearing 47 Wall section 14th Bearing part 48 wall 15th Control part 49 Leaf spring 16 Operating section 50 Furniture 17th end 51 Furniture body 18th Movement element 52 Guide means 19th Guide contour 53 drawer 20th Linear guide 54 Drawer bottom 21 Contact section 55 Drawer front 22nd Adjusting screw 56 Side wall 23 Carrier 57 Drawer back wall 24 Latch component 58 contraption 24a Guide pin 59 Body side wall 25th Guideway 60 Leg spring 26th Stop element 61 Synchronous rod 27 Guideway 62 contraption 28 - 63 Linear guide 29 Plant section 64 External thread 30th Tension lever 65 Attachment section 31 Journal 66 Stop element 32 Holding organ 67 organ 33 Spring element 68 Guide section 69 attack 71 Guide pin 70 attack 72 opening
