Description

State of the art

In furniture parts such as drawers, furniture doors or furniture flaps, which are movably received on a furniture body of a furniture via guide means, devices for influencing the movement of the furniture part are used. Such devices are e.g. formed by a unit which is attachable to the furniture part, the furniture body or the guide means at a suitable location.

The guide means comprise in particular a sliding guide such as a full or partial drawer or a pivoting guide such as a furniture hinge.

In modern and user-friendly furniture devices for the movement of the furniture part are known, for example, which can optionally be provided to provide an additional function, in particular to facilitate a user to open the furniture part. The additional function is particularly tunable to the type and size of the furniture part.

The device for influencing the movement of the furniture part relates z. B. systems for providing a power assisted opening function for the furniture part.

Purpose and advantages of the invention

The object of the present invention is to advantageously provide an additional function for a furniture part movement by means of a sliding guide, such as a full or partial extension, or a pivoting guide, in particular to provide a functionally reliable standby position and triggering a force-assisted opening movement of the furniture part on a first part of the opening path.

This object is solved by the independent claims.

In the dependent claims advantageous variants of the invention are shown.

The invention relates to a device for moving a movable furniture part in an opening direction of the furniture part with respect to a furniture body 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, wherein the device comprises a force storage device so that with the mounted device, the movable furniture part can be brought under the action of the energy storage in the opening direction, and wherein the device comprises a locking arrangement for locking a clamping position of the energy accumulator, in which the energy storage is loaded for the opening movement of the furniture part, wherein the clamping position is unlockable. The invention particularly relates to a furniture part opening device.

The essence of the invention is that a locking member of the locking arrangement and a movable, coupled to the power storage lever of the device are cooperatively present such that in the locked clamping position of the energy storage, the locking member occupy a locking position and the lever a waiting position in which a suspension of the waiting position of the lever is blocked by the locking member. This is advantageously a reliable and functionally many times identically repeatable locking and unlocking guaranteed. In addition, with the invention, a low-noise and low-friction locking and unlocking possible.

In particular, a comparatively short unlocking path of the locking member is advantageously provided for releasing the locking or out of the locking position into the unlocked position. The release of the lock usually requires an action from the outside by a user z. B. as a triggering or unlocking action.

Preferably, the inventive device for triggering the unlocking process from the outside on a so-called touch-latch function or a touch-latch arrangement. With integrated touch-latch function, the furniture body closed and held in the closed position usually furniture part is moved by a movement of the furniture part in the closing direction over a relatively short path of movement of the furniture part, which describes the unlocking process. The unlocking process is a prerequisite for the force-supported by the power storage opening movement of the furniture part.

Moving the furniture part to trigger happens by the user from the outside, for example, pushes against a front of the furniture part.

For example, a cooperating with the locking member triggering element of the device is thereby moved linearly or translatorily, whereby the locking by a Adjustment of the locking member can be canceled. With the invention, the linear release path of the furniture part and thus the trigger element is advantageously reduced to a relatively short trip distance such as a few millimeters. The device is advantageously distinguished by a high reliability of locking and tripping.

After pressing the furniture part, when the user no longer acts on the furniture part, wherein the unlocking is completed, the furniture part is moved from the closed position on the furniture body in the opening direction under the effect of the charged or tensioned energy storage. The moving out of the furniture part such as a drawer relative to the furniture body under the force storage effect via at least a portion of a maximum of the guide means provided opening path of the furniture part on the body.

The device according to the invention is preferably designed so that is reloaded with a closing movement of the furniture part relative to the furniture body of the partially discharged during storage power storage is again brought into the clamping state. The force required for this purpose is applied by the user when the user presses the furniture part in the closing direction. After the end of the tensioning operation with the locking member in the locked position can advantageously be an automatic retraction, the z. B. is integrated in the guide means, bring the furniture part to, for example, a few inches in the fully closed to the furniture body position. The closed furniture part then waits for the next release operation.

The lever may in particular be a coupling element of a coupling device which is present between the energy store and an ejector component. The ejector member is displaceable under the force storage effect on the device, whereby the furniture part from the closed position in the Opening direction can be brought. The coupling device is effective when the user closes the furniture part and while the ejector is displaceable by means of the coupling device, whereby the energy storage is brought into the clamping position.

The lever is movably mounted on the device preferably pivotally, wherein the lever via the at least substantial relaxation process of the energy store when opening the furniture part performs a movement.

In the clamping state of the energy storage is the locked lever in the resting and blocked by the locking member waiting position. The waiting position describes a start swivel position for the next opening process. The lever is locked in the direction in which the lever moves after unlocking.

The blockage accordingly prevents movement of the lever in a relaxation direction.

So that the locked or blocked lever is defined or permanently ready for the opening of the furniture part, the lever is biased under the action of the charged energy storage in the relaxation direction. In this direction, the locking member forms a mechanical stop for the lever. The lever is preferably coupled for movement with the force accumulator, that the position of the moving or pivoting lever in a pivoting direction continuously changes when the energy storage discharges from the clamping state with the opening of the furniture part, and continuously pivots back into the other pivoting direction, if the energy storage is stretched again.

The locking member is preferably positioned so that the locking member is in the locked state in the path of movement of the lever. With the release of the lock becomes the blockage of the movement path of the lever free and the lever pivots past the moving away locking member.

Advantageously, the lever has a contact portion, which occupies a blocked state in the waiting position of the lever or comes into contact with the locking member. The contact portion is preferably adjustably received on the lever, in particular reversibly from a projecting into a recessed position brought. In particular, the lever can be brought into contact only with the contact portion with the locking member. Preferably, the contact portion is preloaded on the lever present preferably biased in the direction of a lever projecting state. The bias is realized for example with a spring. The spring urges the contact portion into a position in which the contact portion and thus the lever on the locking member is blocked. In the locking position of the lever on the locking member of the contact portion is brought under the bias in the contact position on the locking member.

In particular, the contact portion is present at a portion of the lever remote from a pivot axis of the lever over a substantial length of the lever.

The contact portion is in the locking state lying flat on the locking member. Thus, despite the safe blockage a pivoting away of the locking member from the contact portion quiet and trouble-free possible. Preferably, a Verhakungszustand between the contact portion and the locking member is avoided with the invention, which would possibly be susceptible to interference with regard to the establishment and / or release of the locking state.

In particular, it is advantageous that the locking member is movably mounted, in particular pivotable. The locking member can advantageously be moved or pivoted be brought into the lock state and out of this. In particular, only a small trip path of a trigger element is necessary to safely cancel the lock with a small pivoting of the locking member. Preferably, the locking member is pivotable about an axis which is aligned transversely to the pivot axis of the lever.

Further, it is advantageous that the locking member is biased. In particular, the locking member for unlocking evades the bias. The locking member is biased in the direction of its locking position and its locking position. Advantageously, in this way the locking position under the action of the bias safely set up and controlled canceled again. After releasing the lock, the locking member automatically returns under the bias in the locking position when no counteracting force canceling counteracting force is effective.

When unlocking the locking member is deflected against the action of the bias, for which a Aufhebungskraft from the outside is necessary. This force is applied when triggered by the user. Once the user releases, the locking member is pushed back into the locking position. As a biasing element for the locking member, for example, a spring is preferably a leaf spring in question.

It is also advantageous that the contact portion is mounted deflected from the blocked state. By dodging relative to the lever in particular the tensioning of the energy storage can be advantageous. It is advantageous to offset the relaxation of the contact portion and maintained until the end of the clamping process, that for no force during clamping must be applied, which is advantageous for the clamping operation, since when clamping a comparatively large force is applied by the user anyway or so further force is necessary for pushing back the contact section.

Preferably, the contact portion is spring loaded, for example with a leg spring.

In particular, it is advantageous that when setting the lock, the locking member may remain in its locking position, which in the comparatively critical phase at the moment of the establishment of the locking a malfunction due to a movement of the locking member is excluded or minimized. Because the locking member does not need to be adjusted because it is already in the locked position. Only when the triggering operation, the locking member is briefly moved out of the locking state and immediately returned to the locking state. Thus, the locking member remains even at the end of the clamping operation in the locked position and must not leave this, so that the contact section passes it to get into the blocked position. Rather, according to the invention, the contact section deviates from the blocked state and, after passing through the stationary locking element, passes prestressed into the blocked position.

The return of the comparatively small and light contact portion in the blocked state is not critical.

The contact portion deviates during the clamping operation of the force accumulator on the locking member in a lever on the not or less projecting position, which happens only shortly before reaching the locking state, whereby the lever passes the locking member. After passing the locking member passing the contact section immediately returns automatically by the bias and safely in the locked state and is blocked on the locking member.

This is done without pressure, since with the momentum at the end of the clamping operation, the lever swings a little further in the clamping direction of the locking member and thus the contact portion can safely reach the protruding position before the lever abuts after releasing the clamping force with the projecting contact portion against the locking member and is blocked.

The contact portion is accordingly biased in the direction of the locked state or biased in a swung-out position with respect to the lever.

An advantageous modification of the invention is characterized in that the contact section is designed on a pivotable pawl. This is a particularly compact and reliable design principle. The pawl can be pivoted in against a spring effect. The contact portion is preferably designed flat z. B. formed by a component edge.

According to an advantageous variant of the invention, the locking member and the lever are tuned such that leaving the locking position of the locking member is a prerequisite that the waiting position of the lever can be canceled. For leaving the locking position advantageously already sufficient a slight movement of the locking member out of the dormant locking position. The slight movement may in particular be a small pivoting movement by a few angular degrees about the pivot axis of the locking member. With movement blockage of the lever is suspended. When the lever or the contact portion on the locking member comes out of contact, the locking member is returned to the locking position.

It is also advantageous that the locking member and a support portion are tuned to the lever such that when leaving the locking position of the locking member of the support portion on the Locking member acts, wherein the locking member moves away from the locking position. When triggered, the locking member is advantageously advanced by the support portion an additional path of movement in the direction which further removes the locking member from the locking position.

In particular, the locking member is moved away or pivoted away from the support portion to the additional movement path or by further degrees from the locking position with the leaving the locking position without change of direction.

The further movement of the locking member takes place in particular with the lever movement when relaxing the force accumulator after unlocking. The displaceable support portion on the lever may or may not be movable relative to the lever.

It is also advantageous that the contact portion and the support portion are configured on the lever on a common component. This is in particular a pivotable pawl on a lever such as a guide lever or on a lever attachment of a guide lever. With the support portion which is effective immediately after the necessary to unlock the locking member movement of the locking member, the movement of the locking member is preferably forcibly increased by a predetermined movement path positively controlled.

The movement extension is with regard to a transmission of movement from the locking member to another element such. B. an element of a functional unit advantageous. The functional unit is a device separate from the device and spaced therefrom. Often it is necessary that a synchronous and complete transmission of the movement of the locking member, in particular with respect to the unlocking process, is transferred to the element of the functional unit. This must be ensured be that the movement of the locking member relative to the necessary movement of the locking member, which is sufficient for unlocking, is increased. Because with the motion transmission over z. As a connecting element is lost a loss of movement on the transmission lost. The transmission of movement is preferably realized with the connecting element which connects physically between the locking member and the element.

For a movement to arrive at the element of the functional unit to the extent that is required for the element, the loss share must be taken into account on the connection path with the connecting element. The loss share is due to material properties and / or component tolerances. Therefore, the movement of the locking member during the unlocking process must be increased, so that this increased movement can be absorbed by the connecting element and is transferable to the element of the functional unit. There then comes to a movement that is sufficient or at least equal to the degree of movement of the locking member that executes this without enlargement with the support portion.

An advantageous variant of the invention is characterized in that the locking member and the lever are matched to each other, so that the lever can be moved past the locking member during a tensioning of the force accumulator, wherein the lever can be brought into the waiting position. Thus, advantageously, the locking position can be set up immediately and safely. In particular, the contact portion during clamping or possibly the pawl gives way by resting on the locking member on the lever. Due to the bias of the pawl, this automatically returns to the protruding position on the lever as soon as the lever is moved past the locking member. Thus, the contact portion in the waiting position of the lever on the locking member is brought into abutment. The lever is thus in the action of the tensioned energy storage by the Locking member adjacent thereto blocked in the corresponding unlocking direction.

The invention also relates to a piece of furniture with a furniture body and a movable furniture part, which can be brought via guide means in an opening direction of the furniture part and in a direction opposite to the opening direction opposite closing direction relative to the furniture body, wherein a device is provided as explained above. Thus, the above advantages can be set to a piece of furniture, especially on a piece of furniture with a drawer or a flap or door. In particular, this is advantageous in furniture, which have in a guide or a full extension automatic feed with which the furniture part in the fully closed position on the furniture is retractable.

In particular, the furniture also comprises a device as explained and a twin device, wherein a touch-latch function is synchronized in both devices by a synchronization. For example, thus a safe release of the locking position of the locking member can be set up, regardless of where the force is applied to the furniture part. For example, if a device according to the invention in the range of right side mounted on the furniture part guide means and a twin device in the range of left side mounted on the furniture part guide means are present, the locking member of the right device can safely trigger when acted upon by the user on the furniture part near the right-side device , With the synchronization, the locking member of the left-side twin device is then safely and synchronously triggered or unlocked.

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 includes a drawer bottom 54, a Drawer front 55, two opposite side walls 56 and a drawer rear wall 57. For the guidance of the drawer 53, two equally acting guide means 52 are provided in each case 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 fixed in position on the furniture body 51 and / or on a stationary part of the guide means 52 arranged, corresponds to the opening direction of the drawer 53 of the direction P1 and the closing direction of the drawer 53 of 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 exclusively linearly movable or parallel to the direction of movement of the moving element 18 in the directions P1 and P2 through a 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 Drawer 53 takes place exclusively via a direct operative connection of the energy accumulator 3 via the movement element 18 moving in the direction P2 to 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, 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 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 body 51 or on a positionally fixed part of the guide means 52 of the furniture 50, then the driver 23 on the drawer 53 and be movable to the furniture body 51 be present.

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 member 24 swung out on the ejector 5 abuts on the driver 23, which in the further drawer movement course of the Ejector 5 reaches its maximum far in the direction P2 on the base plate 2 shifted end position. 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 operation of the energy accumulator 3, the ejector unit 1 separates from the driver 23 and the contact between the driver 23 and the contact portion 21 of the adjusting 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 tensioning 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 locking element 41 is configured as a spring-loaded pivotable pawl.

The end position of the discharge state of the energy storage 3 ( FIG. 5 ) is predetermined in particular by a striking of the guide lever 34 on a wall portion 28 of the base plate 2 and / or a striking of the stop member 42 on 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. Does the stop element 42 of the guide lever 34 after a discharge of the energy storage 3 on the wall portion 47, Due to a remaining bias of the coil springs 10, 11, a tensile force in the direction P2 is transmitted from the moving member 18 via the connecting member 35 to the guide lever 34. 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 sections 47, 28 can be designed to be elastic or damping, so that 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.

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 may be due to its storage on slide-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 move 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 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 this for tensioning the Force accumulator 3 is prepared 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 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 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 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 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 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 lever on the top 40 projecting locking element 41st moves with the pivoting operation of the guide lever 34 below the flap 43 past this 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 organs are thus motion-coupled directly and / or synchronously. This represents a contrary principle of synchronization to a physical connection between triggering elements of two ejector devices on a furniture part.

FIG. 10 shows in perspective the guide lever 34 with the lever cap 40 and the locking member 41 with the leg spring 60 increases, with an outline of a locking acting part of a wing-like extension 67 of the flap 43 in the locking state or in abutting contact with the locking element 41 according to the state FIG. 3 is indicated.

The flap 43 forced into the locking state by the leaf spring 49 locks the guide lever 34 against pivotal movement of the guide lever 34 in the direction P3 about the pivot axis S1 of the guide lever 34. The guide lever 34 is biased in the direction P3 under the action of the force accumulator 3 in the clamping state , In this case, the locking flap 43 forms with a part of a marginal narrow side 65 of the extension 67 a mechanical stop for a narrow end-side section 66 on the locking element 41. The section 66 is in FIG. 10 hatched highlighted.

FIG. 11 shows this condition according to FIG. 3 , If after a triggering operation, the flap 43 is pivoted about the axis D in the direction P4 upwards and thus the locking state is canceled by the flap 43, the narrow side 65 is moved away from the section 66, the guide lever 34 pivots in the direction P3, whereby the force-assisted opening movement the drawer 53 takes place.

The pivoting of the flap 43 from the locking position in the direction P4 with respect to the relevant part of the narrow side 65 at the portion 66 takes place by a few, for example, 5 to 10 degrees or by the angle gamma or γ, which of the Height h1 of section 66 depends on, for example, about 1 millimeter. The height of the narrow side 65 preferably corresponds at least approximately to the height h1. After pivoting the flap 43 in the direction P4 upwards by the angle γ, the locking element 41 passes under the extension 67, wherein a bottom of the extension 67 is supported on an upper surface of the locking element 41, with the cooperation of the leaf spring 49, which the flap 43 against the direction P4 urges. The upper side of the locking element 41 acting on the underside against the extension 67 has an obliquely oriented support section 68, so that the flap 43 is raised further in the direction P4 in accordance with the slope of the support section 68. The slope of the support portion 68 rises from the portion 66 against the direction P3 to a dome 69 on top of the locking element 41. The further lifting of the flap 43 by the locking member 41 is carried by the height h2 according to the height of the support portion 68 and the further pivoting upwards preferably takes place by a pivoting amount in the range of the angle γ or something more. Thus, the flap 43 is pivoted in particular by at least 2 * γ in the direction P4.

When the guide lever 34 or the locking element 41 is pivoted past the flap 43 or the projection 67, the flap 43 is returned to the locking position from the pivot position pivoted or raised in the direction P4 under the return action of the leaf spring 49 FIG. 10 or 11 brought. The with the leg spring 60 in the relation to an edge of the lever cap 40 projecting position according to FIG. 10 brought locking element 41 is by abutment against a bent on the base plate 2 extending land shoulder 70 (s. FIG. 3 ) When further pivoting in the direction P3 pushed inwards, so that the locking element 41 on the lever cap 40 projects only slightly. The pushed back position of the locking element 41 remains through the continuous formation of the web shoulder 70 over the entire subsequent pivoting path of the guide lever 34 in the direction P3 and at later pivoting back of the guide lever 34 in the direction opposite P3 obtained during tensioning of the force accumulator 3 until the locking element 41 passes by the extension 67 and behind again under the action of the leg spring 60 in the locking position according to FIG. 3 or 11 pivots and the guide lever 34 is blocked in the direction P3 by the narrow side 65.

FIG. 12 refers to the moment of driving or raising the flap 43 on the basis of the locking element 41 shortly after unlocking the locking position of the guide lever 34. The outline of the locking element 41 under the extension 67 is indicated by dashed lines.

By a rotational movement of the flap 43 about the axis of rotation D, for example when unlocking as described above, with the attached synchronous rod 61 whose longitudinal axis coincides with the axis of rotation D, a torque from the flap 43 of the device 58 to the synchronizer rod 61 and on synchronously transmit a functional unit present on the other end of the synchronizing rod 61 or optionally on a locking member or on a flap of a twin device 62 (see FIG. FIGS. 1 and 2 ).
