Description

Technical Field

[0001] The invention relates to a device for ejecting a movable furniture part, wherein the device is designed to realize and / or support the ejection by force transmission between the device and a drive, wherein the device comprises a housing and a slide which is movable relative to the housing, wherein the slide is movable between a retracted position and an ejected position, wherein the slide comprises a drive stop which is arranged in the movement path of the drive, wherein the slide has a pivot lever which is pivotable between a pivot-in position and a pivot-out position. Background Art

[0002] A device of this type is known from EP 3 133 230 A1. The device comprises a base plate on which an ejector in the form of a carriage is mounted in a linearly movable manner. The ejector comprises a contact section via which a force can be applied to the drive. The device also comprises a force accumulator in the form of a spring. In the closed state of the movable furniture part, the device is in a tensioned state in which the force accumulator is pretensioned to a maximum value. In order to eject the movable furniture part, the tensioned state can be released, whereby the spring force is transferred from the moving element to the ejector. This causes the ejector and therefore the drive to move linearly relative to the base plate. After the force accumulator has been released, the device is in a released basic state. A pivotally mounted latch component is arranged on the ejector. The latch component is guided on a guide track arranged on the base plate. During the movement out of the tensioned state, the latch component is in a pivoted out position and engages behind the drive on the side opposite to the contact section of the ejector. At the end of the movement of the ejector, the catch part moves into a pivoted-in position away from the movement trajectory of the drive, thereby disengaging the movable furniture part from the ejector. The device is then in a waiting position. If the drive now returns to the device, it does not meet the catch part, but hits the contact section of the ejector. In its pivoted-in position, the catch part rests against the mounting pin of the tension rod. The tension rod is connected to the accumulator via a rod mechanism. The movement of the drive in the direction of the tensioned state loads the accumulator via the rod mechanism. Before the tensioned state is reached, the pivot rod is then pivoted away from the mounting pin of the tension rod, allowing displacement along the linear guide on the drive. The drive is thus disengaged from the force action of the accumulator and can be further displaced in the direction of the closed state of the movable furniture part. This results in a free run of the carriage at the end of the retraction movement of the movable furniture part until the original closed state is restored. During the free run, for example, an automatic retraction mechanism can act on the movable furniture part.

[0003] A disadvantage of the known device is that, in order to be able to achieve free running at the end of the retraction movement, the ejector must be released from the force accumulator. For this purpose, the known device requires that the force transmission between the ejector and the force accumulator during the ejection movement on the one hand and during the retraction movement on the other hand must be realized by separate devices. In fact, during the ejection movement, the transmission between the force accumulator and the carriage is realized by a stop element. During the retraction movement, on the other hand, the force is transmitted via a complex rod mechanism. This leads to increased parts and assembly costs. In addition, the movement sequence of the individual elements must be precisely coordinated so that the ejection movement and the retraction movement can occur reliably and as expected. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a device of the above-mentioned type which is characterized by a reduced number of components and a simplified design.

[0005] This object is achieved in that the pivot lever has a further drive stop which is arranged in the movement trajectory of the drive in the ejection position and which is pivoted away from the movement trajectory of the drive in the pivot-in position in the ejection position or in the movement range of the slide between the ejection position and the retracted position.

[0006] In this case, it is conceivable that the device is arranged on the furniture body and the drive is arranged on the movable furniture part. However, it is also possible that the drive is arranged on the furniture body and the device is arranged on the movable furniture part. The movable furniture part can be, for example, a drawer. It is also possible to provide more than one device. In particular in the case of wide drawers, it is convenient to provide two devices, for example on both sides of the drawer.

[0007] The ejected position can represent a waiting position, for example when the movable furniture part is ejected. In this case, the movable furniture part can be in an open or partially open position. When the movable furniture part moves toward the closed position, the drive encounters a further drive stop on the pivot rod, since the further drive stop is located in the movement trajectory of the drive in the ejected position.

[0008] If the movable furniture part is now closed further, a force can therefore be transmitted from the drive to the carriage via the pivot lever.

[0009] Since the other driver stop is pivoted away from the motion trajectory of the driver in the retracted position or in the range of movement of the carriage between the ejection position and the retracted position, the driver can move towards the terminal end of the insertion movement past the driver stop. This prevents power transmission between the driver and the carriage to a minimum extent. Therefore, the driver has free running. It should be emphasized that the free running of the driver occurs between the driver stop and the other driver stop of the carriage. Therefore, there is no need to provide free running of the carriage itself. Therefore, there is no need to provide a mechanism for releasing the carriage. This reduces parts and assembly costs.

[0010] It is conceivable that the device can be pre-tensioned. In particular, a pre-tensionable spring element can be provided. In this case, the carriage can be connected to the spring element, for example, even during free running of the drive, in particular allowing force transmission.

[0011] Furthermore, by not requiring free play of the carriage, the number of moving parts may be reduced and / or the required travel of the moving parts may be reduced.

[0012] If a movable trigger is provided which prevents the slide from being moved from the retracted position in the blocking position and prevents the slide from being released in the release position, the slide can be held in an advantageous manner in the retracted position and, if necessary, can be released, in particular if an opening movement of the movable furniture part is desired.

[0013] It can also be provided that a latch is provided, wherein the latch allows the pivot lever to pivot from the pivot-in position to the pivot-out position within the range of movement between the retracted position and the ejected position, and wherein the latch prevents the pivot lever from pivoting from the pivot-out position to the pivot-in position within the range of movement between the ejected position and the retracted position. This can prevent the pivot lever from pivoting unintentionally from the pivot-out position. It can thus be ensured that the further drive stop is reliably located in the movement trajectory of the drive.

[0014] According to an advantageous embodiment of the invention, it is proposed that a guide element is provided on the pivot lever, a guide track is provided on the housing, and the guide element is guided in the guide track. With the guide track, a movement of the carriage can be easily converted into a pivoting movement of the pivot lever. Conversely, a movement of the carriage can also be prevented by fixing the guide element. If it is therefore further provided that a first braking section is provided on the guide track, the guide element can be held at the first braking section in the at least partially pivoted position of the pivot lever, in particular when the carriage is in the retracted position, the carriage can therefore also be held in the retracted position.

[0015] Additionally or alternatively, provision can be made for the second braking section to be arranged on the guide rail, wherein the guide element can be held on the second braking section in the pivoted-out position of the pivot lever, wherein preferably the guide element is held at the second braking section when the carriage is in the ejection position. Thus, it is ensured that the pivot lever is held securely in the pivoted-out position. In particular, it is also achieved that in the ejection position the further drive stop is located in the movement path of the drive.

[0016] The guide element can be pin-shaped, for example, in particular a guide pin.

[0017] A variant of the invention may be that the guide track has an ejection section, the trigger in the blocking position preventing the guide element from moving from the first braking section into the ejection section, and releasing the movement in the release position. The ejection section may preferably be arranged after the first braking section. When the movement of the guide element is released, the guide element may be displaced along the ejection section when the carriage moves between the retracted position and the ejection position. If the movement of the guide element is prevented, the carriage may be securely held in the retracted position.

[0018] In particular, it can be provided that in the blocking position the trigger projects into the guide track via the retainer attachment and that the retainer attachment can at least partially move out of the guide track when the trigger is moved into the release position. Thus, a displacement of the guide element from the first braking section to the ejection section can be prevented and / or allowed in a particularly simple manner.

[0019] According to the invention, it can also be provided that the guide track further comprises a pivot-out section, and that the pivot lever can be pivoted from the pivot-in position to the pivot-out position by displacement of the guide element along the pivot-out section toward the second braking section. The pivot-out section can preferably follow the ejection section. Thus, the transfer of the pivot lever to the pivot-out position can be achieved at the end of the ejection process.

[0020] If it is provided that the latch allows the guide element to be displaced from the unscrewing section into the second braking section, and the latch prevents the guide element from being displaced from the second braking section into the unscrewing section, it can be easily ensured that the other drive stop is reliably located in the movement trajectory of the drive when the carriage is in the ejection position. It is also possible to effectively prevent the unintended return of the guide element, in particular to the unscrewing section. The latch can be designed in particular as an elastic element. For example, the latch can be retained in the region between the ejection section and the unscrewing section and / or in the region between the unscrewing section and the second braking section. It is conceivable that when the guide element moves in the desired direction, in particular from the unscrewing section to the second braking section, the guide element exerts a force component on the latch. This can cause the latch to be elastically displaced and / or deformed, and thereby release the conversion from the unscrewing section to the second braking section.

[0021] According to a preferred embodiment of the invention, it can be provided that the force exerted by the driver on the further driver stop of the pivot lever exerts a torque on the pivot lever, which torque is at least partially or predominantly directed in the direction of the pivoting-in movement of the pivot lever, in particular, this torque causes and / or supports the pivoting-in in the retracted position or in the range of movement between the ejected position and the retracted position. Since the pivot lever is pivotably mounted on the carriage, the forces on the further driver stop cause a torque about the pivot axis of the pivot lever when they are not directed directly toward the pivot axis. Such a torque can therefore advantageously be used to cause and / or assist the pivoting-in of the pivot lever.

[0022] Alternatively or additionally, the guide track may also have a screw-in section. This screw-in section may, for example, follow the retraction section. When the carriage moves from the ejected position to the retracted position, the guide element may move along the screw-in section and thus enter the screw-in section. The screw-in section and / or the torque applied by the force of the drive may be used to achieve the pivoting movement.

[0023] If it is provided that the drive stop comprises a deflection roller and that the deflection roller is rotatably mounted on the pivot lever, friction losses between the drive and the further drive stop can be reduced, in particular during the pivoting movement of the pivot lever. This can lead to reduced wear on the contact surfaces and / or to a more uniform movement profile.

[0024] In this case, it can be preferably provided that the deflection roller comprises a soft material, in particular an elastic and / or damping material. In this way, undesirable noises due to the contact between the drive and the further drive stop can be minimized. Soft plastic or rubber materials are conceivable. In particular, the deflection roller can also consist of two different materials. For example, it is conceivable that the contact surface with the drive is made of a softer material than the bearing point opposite the pivot lever. Preferably, such a deflection roller can be manufactured by a two-component process, in particular by a two-component injection molding process.

[0025] A variant of the invention is characterized in that the carriage comprises a pusher, which is movable relative to the carriage, an actuating surface of the pusher forming a drive stop, a push surface also being arranged on the pusher and designed to actuate a trigger. Thus, for example, when the movable furniture part is in the closed position, the drive can displace the pusher relative to the carriage due to the action of a force, in particular due to an overtravel exerted by a user on the movable furniture part. The push surface then transmits the force to the trigger, which can trigger the ejection process. The carriage can remain in the retracted position during this period.

[0026] If it is further provided that the pusher is mounted on the carriage in a biased manner by a spring, it is ensured that the pusher returns to its initial position after the release process. In particular, this ensures that the drive stopper returns to the appropriate position required for the ejection process relative to the carriage.

[0027] According to an advantageous variant of the invention, it is provided that a spring element is provided, by which the carriage is held biased in the retracted position relative to the housing, and by which the carriage is preferably moved from the retracted position into the ejected position by the spring element when the pretension of the spring element is reduced. Thus, ejection of the movable furniture part can be supported and / or enabled by the reduction of the pretension. Furthermore, the carriage can be securely held in the retracted position.

[0028] A particularly simple and reliable transmission of force between the spring element and the slide can be achieved if it is further provided that the spring element is mounted on one side on a spring slide, the spring slide is movable relative to the housing, the slide has a stop surface, the spring slide has a mating stop surface, and the force can be transmitted from the spring element via the stop surface and the mating stop surface to the slide.

[0029] In this case, it can be provided in particular that during the movement of the carriage from the ejection position into the retracted position, a force is transmitted between the stop surface and the counter-stop surface and that the pretension of the spring element is increased by the transmitted force. Thus, during the insertion movement of the movable furniture part, the pretension of the spring element is increased again in a simple manner. In particular, no additional means such as a lever mechanism are required to increase the preload of the spring element. Furthermore, the stop surface and the counter-stop surface can be in constant contact, for example during a movement sequence between the retracted position and the ejection position of the carriage (preferably in both directions). This can lead to a reduction in noise, since the two surfaces are prevented from colliding with each other.

[0030] According to the invention, it can also be provided that the pivot rod has a deflection attachment, on which a deflection surface is arranged, and the deflection surface is adjacent to another drive stop and is arranged at an angle to the other drive stop. Depending on the geometric extension of the drive, when the carriage approaches the ejection position, the drive may not have completely left the area of ​​the pivot rod. In this case, the pivoting of the pivot rod can initially be blocked by the drive. The pivot rod can then rest on the drive by the deflection surface. The deflection surface can be aligned with the other drive stop at an angle so that it extends substantially along the movement trajectory of the drive, so that the drive can slide along the deflection surface. This prevents the pivot rod from blocking the further extension of the movable furniture part. However, when the drive has moved out of the range of the pivot rod, the pivoting out can be unimpeded.

[0031] A variant of the invention is characterized in that the deflector is arranged on a carriage, the deflector is pivotably mounted on the carriage, the deflector is mounted on a pivot rod so that it can be pivoted and preferably displaced, the deflector can be moved into a retracted pivot position by pivoting the pivot rod in, and the deflector can be moved into an extended pivot position by pivoting the pivot rod out, wherein the rotation direction of the pivotal movement of the deflector is each opposite to the rotation direction of the pivotal movement of the pivot rod, and the deflector has a deflection surface facing away from the carriage, which extends at least partially along the longitudinal extent of the deflector.

[0032] Thus, the deflector is in the retracted pivot position when the pivot rod is also in the pivoted-in position, in particular when the carriage is in the retracted position. In the retracted state of the movable furniture part, the drive is located between the drive stop and a further drive stop, which is located outside the movement trajectory of the drive. If the drive is now moved in the direction of the ejection position by the drive stop during the ejection process, it may be necessary to prevent the pivot rod from pivoting out when the carriage approaches the ejection position. In particular, if the drive is selected to have an extension in the direction of its movement trajectory that is less than the distance between the drive stop and the further drive stop, the drive may collide with the pivot rod. This would prevent further extension of the movable furniture part. The deflector reliably prevents this by preventing the pivot rod from pivoting out when the drive is located between the drive stop and the further drive stop.

[0033] According to the present invention, it can also be provided that the housing comprises a first housing half and a second housing half, and the guide rail is provided on at least one of the housing halves, preferably the guide rail is provided on both housing halves.

[0034] The guide track can be formed by the housing, in particular an integral part thereof. However, it is also conceivable that the guide track is formed by another part of the device, in particular the guide track can be a separate part, for example accommodated on the housing. If the housing is divided, for example with two housing halves, the guide track can be arranged on one or both housing halves, in particular the guide track can be formed integrally by each of them or accommodated on each of them. This ensures reliable guidance of the guide element.

[0035] According to an advantageous further development of the invention, it is proposed that the carriage comprises a preferably arc-shaped guide rail, through which the guide element of the pivot lever protrudes, and / or that the carriage comprises a preferably arc-shaped guide recess, wherein the pivot lever has a guide projection, and wherein the guide projection is guided in the guide recess. In this way, a reliable guidance of the pivoting movement of the pivot lever relative to the carriage can be achieved in a simple manner. Furthermore, the bearing point of the pivot lever on the carriage can be mechanically released, since forces can be absorbed via the guide rail and / or the guide recess.

[0062] Figure 1 A schematic exploded view of the device is shown. Figure 1 and Figure 2 As can be seen, the device 1 can have a housing 9 which can include a first housing half 10 and a second housing half 20 . Figure 2 A schematic top view of the device 1 is shown, wherein the second housing half 20 is not shown. This can correspond, for example, to a situation in which the second housing half 20 has been removed.

[0063] As from Figure 1 and Figure 2 As can be seen, the device 1 may include a carriage 30, which may be movably mounted relative to the housing 9. The carriage 30 may include a drive stop 51. The drive stop 51 may be provided on a pusher 50, which may be movably supported on the carriage 30. The pusher 50 may be biased by a spring 55 on the carriage 30.

[0064] like Figure 1 and Figure 2 As further shown in , the device 1 can further include a pivot rod 40. The pivot rod 40 is pivotally mounted to the carriage 30. A further drive stop 45 can be arranged on the pivot rod 40. The pivot rod 40 can include a guide element 42, which can be configured as a guide pin. In addition, a deflector 49 can be provided. On the one hand, the deflector 49 can be pivotally and / or movably mounted on the carriage 30, and on the other hand, the deflector 49 can be pivotally and / or movably mounted on the pivot rod 40.

[0065] The device 1 may further comprise a trigger 90. The trigger 90 may be movably arranged on the housing 9. In particular, the trigger 90 may be biased relative to the housing 9 by a return spring 99.

[0066] As from Figure 1 and Figure 2 As can be further understood, the device 1 can include a spring element 65. The spring element 65 can include two tension springs, in particular helical springs. The spring element 65 can be mounted on one side on a spring carriage 60. The spring carriage 60 can be mounted on the housing 9 so as to be movable, in particular linearly displaceable.

[0067] The spring carriage 60 may have a transfer attachment 62. The force may be transferred between the transfer attachment 62 and the clamping attachment 38 of the carriage 30 (see Figure 4 ) between them.

[0068] On the side of the spring element 65 opposite to the spring carriage 60, the spring element 65 can be supported on a support element 75. The support element 75 can be moved relative to the housing 9. Thus, the preload of the spring element 65 can be changed. Figure 2 As can be seen in the figure, an adjusting lever 70 can be provided for adjusting the bearing element 75. The adjusting lever 70 is mounted on the housing 9 in a pivotable manner, for example.

[0069] like Figure 1 , 2 As can be seen in FIG. 22, the device 1 may include a first synchronization element 101 or a second synchronization element 105. The synchronization elements 101, 105 will be further discussed elsewhere herein.

[0070] Figure 3 1 shows a schematic top view of the first housing half 10. As can be seen from the figure, the first housing half 10 can include guide receptacles 11.1, 11.2, 11.3, 11.4. The guide receptacles 11.1, 11.2, 11.3, 11.4 can be used to guide the carriage 30. For this purpose, projections 32.1, 32.2, 32.3 can be provided on the carriage 30, as shown in FIG. Figure 6 As can be clearly seen in FIG. The projections 32.1, 32.2, 32.3 can be guided, for example, in the guide receptacles 11.1, 11.2, 11.3, 11.4. In particular, the guide receptacle 11.4 can be designed as a guide rail.

[0071] As from Figure 3 As can be further seen in FIG. 1 , the guide track 12 can be further arranged on the first housing half 10. The guide track 12 can be used to guide the pivot rod 40. For example, Figure 7As shown in , the pivot lever 40 may include a guide element 42. The guide element 42 may be pin-shaped. The guide element 42 may be guided in the guide track 12.

[0072] also, Figure 3 As can be seen in FIG. 1 , the first housing half 10 can have a spring carriage guide 13. The spring carriage 60 can be guided on the spring carriage guide 13 in a linearly movable manner. In particular, the spring carriage 60 can be latched to the spring carriage guide 13. For this purpose, for example, latching hooks 13.1, 13.2 can be provided on the spring carriage guide 13. As can be seen from FIG. Fig.19 and 20 As can be seen in the figure, the spring carriage 60 can have guide webs 64.1, 64.2. The guide webs 64.1, 64.2 can be engaged at the rear by latch hooks 13.1, 13.2, for example.

[0073] Furthermore, the first housing half 10 can include a bearing element guide 15. The bearing element 75 can be guided at the bearing element guide 15. In particular, the bearing element 75 can be guided on walls 15.1, 15.2 of the bearing element guide 15. The movability of the bearing element 75 relative to the housing 9 can be limited, for example, by stops 15.3, 15.4 arranged on the bearing element guide 15.

[0074] In the region of the bearing element guide 15, the guide rail 14 can also be arranged on the first housing half 10, such as Figure 3 The guide rail 14 can be used to guide the guide element 78.2 of the support element 75 (see Fig. 20 ).

[0075] The first housing half 10 may include a trigger receiving portion 16, such as Figure 3 As further shown in FIG. 1 , the trigger receiving portion 16 can be used to receive the trigger 90. Fig.11 and Fig.12 As can be seen in the figure, the trigger 90 may include a first arm portion 91 and a second arm portion 92. For example, the arm sections 91, 92 may be arranged at right angles to each other. The second arm portion 92 may include an activation surface 93. Figure 3 As can be seen in FIG. 1 , the trigger receiving portion 16 can have an arm opening 16.2, through which the second arm portion 92 can at least partially protrude from the housing 9. Thus, the activation surface 93 is accessible from outside the housing.

[0076] At the first arm section 91, the trigger 90 may include a retainer attachment 98. The trigger receiving portion 16 may have a retainer hole 16, which can be used to connect to the guide rail 12. The guide rail 12 will be discussed in more detail elsewhere in this document. The retainer attachment 98 can be guided into the area of ​​the guide rail 12 through the retainer hole 16.1. Preferably, a damper receiving portion 91.1 is provided in the region of the retainer attachment 98 on the trigger 90, in which a damper can be received. The damper can preferably be made of a soft and / or damping material.

[0077] The trigger 90 can be movably mounted on the housing 9. In particular, the trigger 90 can be moved by the rear side 97 (see Fig.12 ) abuts against the bottom 16.6 of the trigger receiving portion 16. In addition, a guide web 16.3 can be provided on the trigger receiving portion 16, which can engage in the recess 97.1 of the trigger 90 (see Fig.12 ).

[0078] like Figure 3 As can be further seen in FIG. 1 , the spring bearing 16.4 can be arranged on the first housing half 10. The return spring 99 can be held on the spring bearing 16.4. For example, the return spring 99 can be a torsion spring. The return spring 99 can counteract the displacement of the trigger 90. The trigger receiving part 16 can include a spring holder 16.5, to which the first leg 99.1 of the return spring 99 can be held. The second leg 99.2 can, for example, be supported on the support area 92.1 of the trigger 90 (see FIG. 1 ). Fig.11 ).

[0079] Figure 3 It is shown that the first housing half 10 can have an axial opening 17. The axial opening 17 can receive the synchronizing element 101, 105. For example, the synchronizing element 101, 105 can be inserted or positioned in the axial opening 17. The axial opening 17 can have a neck 17.1, against which the abutment portion 103, 107 of the synchronizing element 101, 105 can abut in a rotationally supported manner.

[0080] Furthermore, the cutout 17.3 can be provided in the region of the shaft opening 17, such as Fig.23 . Preferably, the cutout 17.3 can be provided at the first housing half 10. The cutout 17.3 can represent an opening in the housing wall. Through the cutout 17.3, a part of the shaft opening 17 can be approached from a direction transverse to the central longitudinal axis of the shaft opening 17. It is also conceivable to provide the cutout 17.3 on the second housing half 20 or on both housing halves 10, 20.

[0081] As already mentioned, the guide rail 12 can be arranged on the first housing half 10. The guide element 42 of the pivot lever 40 (see Figure 4 ) can be guided in the guide track 12. The guide track 12 can be designed as a closed-loop rotating guide. The rotation direction can correspond to Figure 3 The guide track 12 may have a first braking section 12.1 and a second braking section 12.4. Between the first braking section 12.1 and the second braking section 12.4, the guide track 12 may have an ejection section 12.2 and a rotation-out section 12.3 in the rotation direction. Between the second braking section 12.4 and the first braking section 12.1, the guide track 12 may have a retraction section 12.5 and a rotation-in section 12.6.

[0082] exist Figure 7 and Figure 8 4. The pivot lever 40 is shown in more detail in FIG. The pivot lever 40 can have an arm section 40.1, which adjoins a curved section 40.2 at an angle. A pivot lever bearing area 41 can be provided on the arm section 40.1. The pivot lever bearing area 41 can be in the form of a hole, as shown herein. A pivot lever brake area 41.1 can be provided in the area of ​​one side of the pivot lever 40, currently in the area 40.4 of the pivot lever underside. For example, the pivot lever brake area 41.1 can form a surface area that is set back relative to the pivot lever underside 40.4.

[0083] A further drive stop 45 may be provided at the curved section 40.2. A further drive stop 45 may be provided as a deflection roller 45.1 which may be rotatably mounted on the pivot lever 40. Preferably, the deflection roller 45.1 may be made of a soft and / or damping material.

[0084] As from Figure 7 As can be seen further in the figure, the deflection attachment 46 can be arranged in the region of the further drive stop 45. The deflection attachment 46 can protrude beyond the pivot lever 40 in its thickness, for example in such a way that the deflection attachment 46 protrudes beyond the pivot lever upper side 40.3 and / or beyond the pivot lever lower side 40.4. On the side facing away from the pivot lever 40, the deflection attachment 46 can include a deflection surface 46.1.

[0085] The guide element 42 can be arranged on the pivot lever 40. Preferably, the guide element 42 can be arranged in the transition area between the arm section 40.1 and the curved section 40.2. The guide element 42 can be pin-shaped, for example. Figure 7 and Figure 8As can be seen further in FIG. 4 , the guide element 42 can protrude beyond the pivot lever upper side 40.3 and the pivot lever underside 40.4. A guide projection 42.1 can also be arranged in the region of the guide element 42. The guide projection 42.1 can have a larger outer diameter than the guide element 42. Preferably, the guide projection 42.1 is arranged concentrically with the guide element 42. Compared to the guide element 42, the guide projection 42.1 can protrude less far beyond the pivot lever upper side 40.3 and / or the pivot lever underside 40.4.

[0086] like Figure 7 As further shown, a guide projection 48 may be formed on the pivot lever upper side 40.3. The guide projection 48 may protrude beyond the pivot lever upper side 40.3. In addition, a damper 47.2 may be held on the pivot lever 40, for example in a damper receiving portion 47.1. The damper 47.2 may preferably be made of a soft and / or damping material.

[0087] The pivot lever 40 may also include a deflector receiving portion 44, for example in the form of a recess. Preferably, the deflector receiving portion 44 is formed in the region of the curved section 40.2. Figure 8 As can be seen in FIG. 4 , the deflector receptacle 44 can have a rib receptacle 44 . 1 which is laterally undercut.

[0088] like Figure 6 As can be seen in FIG. 3 , a pivot rod bearing attachment 37.1 can be provided on the carriage 30. This can be a cylindrical protrusion. Furthermore, a latching element 37.2 can be provided in the region of the pivot rod bearing attachment 37.1. The latching element 37.2 can be formed, for example, as a latching lug.

[0089] The carriage 30 may further include a guide rail 34. Preferably, the guide rail 34 may be configured as an arcuate slot passing through the carriage 30. In addition, a guide recess 37 may also be formed on the carriage 30. Preferably, the guide rail 34 and / or the guide recess 37 may be arcuate with a pivot rod support attachment 37.1 forming the center of the arcuate shape.

[0090] like Figure 4 As can be seen in the figure, the pivot lever 40 can be pivotally mounted on the carriage 30, wherein the pivot lever bearing attachment 37.1 of the carriage 30 is accommodated in the pivot lever bearing area 41 of the pivot lever 40. Here, the pivot lever 40 can be held to the carriage 30 by latching the latching element 37.2 to the pivot lever detent area 41.1.

[0091] As shown here, the pivot lever 40 can be inserted into a recess which can be formed in the region of the carriage underside 30.2 of the carriage 30. The guide element 42 can protrude beyond the carriage 30 at the carriage underside 30.2 of the carriage 30. Furthermore, the guide element 42 can extend through the guide rail 34 so that it also overhangs the carriage 30 at the carriage upper side 30.1 of the carriage 30. The guide projection 42.1 can preferably be guided on the guide rail 34. The guide projection 48 of the pivot lever 40 can be guided on the guide recess 37 of the carriage 30.

[0092] Figure 4 It is also shown that the deflector 49 can be mounted in the deflector receiving portion 44 of the pivot lever 40 via the protrusion 49.2. Fig. 9 As can be seen in FIG. 4 , the deflector 49 can have an extension rib 49 . 3 which is laterally and offset in the region of the projection 49 . 2 . The extension rib 49 . 3 can be received in the projection 44 . 1 of the deflector receiving portion 44 of the pivot lever 40 .

[0093] like Fig. 9 As further shown, the deflector 49 may have a deflector bearing receptacle 49.1 in the end region facing away from the protrusion 49.2. The deflector bearing receptacle 49.1 may be a hole, as shown here, and a deflector flange 49.4 may be formed on one side of the deflector 49 along the longitudinal extent of the deflector 49. The deflector flange 49.4 may form a deflection surface 49.5.

[0094] The deflector 49 can be pivotally mounted on the carriage 30. For this purpose, a deflector bearing region 39 can be provided on the carriage 30, such as Figure 6 The deflector bearing region 39 can be formed as a protrusion, for example a cylindrical protrusion. The deflector bearing region 39 can be received in a deflector bearing receiving portion 49.1 to form a pivot bearing.

[0095] like Figure 4 As can be further seen in FIG. 3 , a pusher 50 can be arranged on the carriage 30. The pusher 50 can form a drive stop 51. The pusher 50 can be received in a pusher receiving portion 36 of the carriage 30. Figure 5 The pusher receiving portion 36 is shown in more detail in . Thus, the pusher receiving portion 36 may have a receiving space 36.1 in which the pusher 50 may be at least partially received.

[0096] In the region of the pusher receiver 36 facing the driver stop 51, a support surface 36.4 may be provided which may limit the receiving space 36.1 at least in certain regions. A similarly formed abutment surface 36.3 may be arranged oppositely. Furthermore, the pusher receiver 36 may have a mating latch element 36.2 in the region of the receiving space 36.1 which may be formed as a recess and / or hole as shown.

[0097] Available from Fig.10 A possible design of the pusher 50 is known. The pusher 50 may have a spring support 53 and a spring support 54. A spring 55 may be arranged between the spring support 53 and the spring support 54. The spring 55 may be a compression spring, such as a helical spring. Fig.10 As can be seen in the figure, the spring 55 can be supported by a first spring end 55.1 on the spring support 53. Here, it is conceivable that a retaining projection 53.1 is provided on the spring support 53. For example, the retaining projection 53.1 can be designed as a latching element that can be latched to the first spring end 55.1.

[0098] The spring support 54 may have a transverse extension 54.2 which is smaller than the transverse extension, in particular the outer diameter of the spring 55 in the region of the second spring end 55.2. Fig.10 As can be seen in FIG. 5A , the spring can thus protrude laterally beyond the spring support 54 .

[0099] In the region of the driver stop 51, the pusher 50 can have an actuation surface 51.1 on which the driver 2 can act. A push surface 54.3 can be formed at the end of the pusher 50 facing away from the driver stop 51, in particular at the spring support 54. Furthermore, a counter-support surface 51.2 facing the driver stop 51 can be provided on the spring support 53. The pusher 50 can also include a latching element 56, such as in Fig.10 As can be seen more clearly in b.

[0100] In the installed state (see Figure 4 ), the latching element 56 of the pusher 50 can be latched with the matching latching element 36.2 of the carriage 30. In this case, the latching element 56 and the matching latching element 36.2 can be designed to ensure the movability of the pusher 50, in particular linear movability.

[0101] The second spring end 55.2 of the spring 55 of the pusher 50 can rest against the abutment surface 36.3 of the pusher receiving portion 36 of the carriage 30. In particular, the portion of the second spring end 55.2 that protrudes beyond the spring abutment portion 54 can bear against the abutment surface 36.3. The counterpart support surface 51.2 of the pusher 50 can bear against the support surface 36.4.

[0102] Fig.23 The arrangement of the device 1 and the second device 1' is shown, which are connected to each other via a synchronization shaft 100. Fig. 22 An embodiment of a synchronization shaft 100 is shown by an exploded view in FIG. Thus, the synchronization shaft 100 can be made of several parts. In particular, the synchronization shaft 100 can include a first synchronization element 101 and a second synchronization element 105, which are connected to each other in a rotationally fixed manner via a connecting part 110.

[0103] The synchronization elements 101, 105 can be formed as shafts, respectively. Radially protruding transmission elements 102, 106 can be arranged on the synchronizer elements 101, 105. Fig. 22 As shown in , the transmission elements 102, 106 can be designed as individual circumferentially limited protrusions extending along at least a portion of the longitudinal extent of the synchronizing elements 101, 105. However, it is also conceivable that the transmission elements 102, 106 are formed as elements profiled in the circumferential direction. In particular, it is also conceivable to form teeth.

[0104] Furthermore, the entraining elements 101 , 105 can have an abutment portion 103 , 107 , which can be formed, for example, as a shoulder. Furthermore, the second entraining element 105 can also have a retaining section 108 , which can also be formed as a shoulder.

[0105] The first entraining element 101 can have a profile section 104 in its end region. As shown here, for example, a T-shaped section can be selected. The latching element 104 . 1 can furthermore be arranged in the region of the profile section 104 .

[0106] In contrast, the second synchronizing element 105 may include a coupling section 109 in the end region, which may be formed, for example, by two surfaces formed parallel to each other and to the longitudinal axis of the second synchronizing element 105. A latching element 109.1 may be provided on the surface of the coupling section 109, which may be formed, for example, as a recess.

[0107] The connection of the second synchronization element 105 to the connecting portion 110 can be achieved by the adapter 113. In this regard, the adapter 113 may include a coupling portion 115 having a coupling receiving portion 115.1. The coupling receiving portion 115.1 may be formed to correspond to the coupling section 109 of the second synchronization element 105. The coupling receiving portion 115.1 may be formed in a coupling section 109 receiving area that is radially open on one side. A mating latching element 115.2 may be formed in the coupling receiving portion 115.1. The adapter 113 may be fixed to the second synchronization element 105 in the radial direction by latching the latching element 109.1 with the mating latching element 115.2.

[0108] The profile section 114 can be provided at the end of the adapter 113 facing away from the coupling part 115. The profile section 114 can advantageously be formed similarly to the profile section 104 of the first entraining element 101.

[0109] The connecting portion 110 can be a section cut to length, for example, of a bar or a profile. In its end regions 112, 113, the connecting portion 110 can have a mating profile section 111.2, 112.2 on both sides. The mating profile sections 111.2, 112.2 can be formed as recesses in the end surfaces 111.1, 112.1 arranged at the end regions 112, 113. In particular, the mating profile sections 111.2, 112.2 can be formed to correspond to the profile sections 104, 114. Thus, the mating profile sections 111.2, 112.2 can be formed as T-shaped recesses in the longitudinal end surfaces 111.1, 112.1 of the connecting portion 110. It is conceivable, but not necessary, that the mating profile sections 111.2, 112.2 can have mating latching elements corresponding to the latching elements 104.1, 114.1. Alternatively or additionally, the latching elements 104.1, 114.1 can also be used to achieve a resilient support against the wall of the counter-profile section 111.2, 112.2.

[0110] Fig.13 A cross section of the device 1, 1' is shown with an inserted synchronizing element 101, 105. Fig.13 As can be seen in FIG. 1 , the first entraining element 101 can be inserted into the shaft opening 17 of a device 1 (eg, the first device 1 ). Thereby, the abutment portion 103 of the first entraining element 101 can be supported at the neck 17 . 1 of the shaft opening 17 .

[0111] As from Fig.13b, the second synchronizing element 105 can be inserted into the shaft opening 17 of the second device 1 '. Again, the abutment portion 107 can be supported at the neck 17.1. In addition, the retaining section 108 can be supported on the retaining shoulder 17.2 of the shaft opening 17. Thus, the second synchronizing element 105 can be firmly held in the shaft opening 17 along its longitudinal axis in both directions. In contrast, the first synchronizing element 101 can be held only in one direction, so that when the housing 9 is closed, in particular when the first housing half 10 and the second housing half 20 are assembled, the first synchronizing element 101 can be inserted into the shaft opening 17.

[0112] The coupling section 109 can be arranged in the region of the cutout 17.3 of the shaft opening 17. Thus, the adapter 113 can be connected to the second coordinating element 105 from a direction transverse to the longitudinal axis of the second coordinating element 105. In particular, the adapter 113 can be guided with its coupling portion 115 through the cutout 17.3 onto the coupling portion 109 of the second coordinating element 105.

[0113] The trigger 90 may include a first mating transmission element 95 and a second mating transmission element 96, such as Fig.11 and Fig.12 The counter-transmission elements 95, 96 can be provided as recesses, which are formed corresponding to the transmission elements 102, 106. The counter-transmission elements 95, 96 can preferably be diametrically opposed to each other with respect to the longitudinal axis of the synchronizing elements 101, 105. In particular, provision can be made for the second counter-transmission element 96 to be provided on the extension 94, which is provided in the transition region between the first arm section 91 and the second arm section 92 of the trigger 90.

[0114] Fig.13 a shows a first synchronization element 101, whose transmission element 102 engages with a second mating transmission element 96 of the trigger 90. Thus, the transmission element 102 is oriented to face out of the image plane. The leftward displacement of the trigger 90 in the image plane may correspond to a trigger movement. The leftward movement of the trigger 90 may result in a leftward movement of the transmission element 102, and thus a rotation of the first synchronization element 101 around its longitudinal axis.

[0115] on the contrary, Fig.13 b shows a second synchronizing element 101, whose transmission element 106 engages with a first counter-transmission element 95 of a second trigger 90' of a second device 1'. The second trigger 90' can be constructed in the same way as the trigger 90, but preferably the second trigger 90' does not comprise an extension 94. Therefore, provision can be made for the second trigger 90' to comprise only the first counter-transmission element 95.

[0116] exist Fig.13b, the transmission element 106 is oriented to face the image plane. The movement of the second trigger 90′ to the left in the image plane may also correspond to the trigger movement. The movement of the second trigger 90′ to the left may result in the movement of the transmission element 106 to the left. However, since the transmission element 106 is now pointing toward the image plane, the same as Fig.13 The situation shown in a is the opposite, which results in the second synchronizing element 105 rotating in a direction opposite to the first synchronizing element 101 .

[0117] If the two devices 1, 1' are now in Fig.23 , 105 ', which results in a consistent rotational direction of the synchronization shaft 100 during the triggering movement of the two triggers 90, 90', which is coupled to the synchronization elements 101, 105 in a rotationally fixed manner. Therefore, it is not necessary to provide a second device 1' which is mirror-inverted with respect to the first device 1. Instead, two devices 1, 1' of at least substantially identical design can be synchronized with each other. Preferably, for this purpose, only two synchronization elements 101, 105 of different design need to be used. Preferably, but not necessarily, two triggers 90, 90' of different design can also be used.

[0118] Fig.19 and 20 The spring carriage 60, the spring element 65, the bearing element 75 and the adjusting rod 70 are shown in more detail. As can be seen from the figure, the spring element 65 can include one or at least two tension springs 65.1. The tension springs 65.1 can have a narrowing region 65.3 at their respective ends. A head region 65.4 can abut the narrowing region 65.3, wherein the head region 65.4 can have an enlarged outer diameter compared to the narrowing region 65.3.

[0119] A spring bearing 63 may be provided on the spring carriage 60 to accommodate a spring element 65. Preferably, the spring carriage 60 may form a spring receiving space 61 in which the spring element 65 is at least partially received. The spring receiving space 61 may be delimited by a bottom 64, two side walls 61.1, 61.2 and a rear wall 61.3. Opposite the rear wall 61.3, preferably in the direction towards the bearing element 75, the spring receiving space 61 may be open.

[0120] The spring support 63 may be formed as a recess in the rear wall 61.3 corresponding to the narrowed area 65.3. Preferably, the recess is open in a direction away from the bottom 64. Therefore, the narrowed area 65.3 can be easily inserted into the recess. Fig.19 In the drawing, the spring element 65 is not inserted into the spring support 63 in order to better see the spring support 63 .

[0121] In the end region of the spring carriage 60 opposite the rear wall 61.3, a transmission attachment 62 can be arranged. As can be seen from the figure, a mating stop surface 62.1 can be formed on the transmission attachment 62. The mating stop surface 62.1 can come into contact with the stop surface 38.1 of the clamp attachment 38 of the carriage 30 (see Figure 5 ).

[0122] Opposite the spring carriage 60, the spring element 65 can be mounted on a bearing element 75. For this purpose, a spring mount 73 can be provided, which is preferably designed in a similar manner to the spring mount 63 of the spring carriage 60.

[0123] As from Fig.19 and Fig. 20 As can be further seen, the engagement lever 78 can be pivotally mounted on the bearing element 75. For this purpose, an engagement lever support 77.1 can be arranged on the bearing element 75. For example, the engagement lever support 77.1 can be configured as a hole. The engagement lever 78 can have an engagement lever support extension 78.1 in the end region, which can be held in the engagement lever support 77.1. Preferably, the latching element 75.4 can be arranged on the bearing element 75 in the region of the latching lever support 77.1. The latching element 75.4 can, for example, act on the surface of the latching lever 78 so that the latching lever 78 can be firmly held on the latching lever support 77.1.

[0124] The engagement lever 78 can be received in an engagement lever recess 75.5 on the bearing element 75. The engagement lever recess 75.5 can in particular be formed as a hole and constitutes a pivoting region for the engagement lever 78.

[0125] The guide element 78.2 may be provided on the engagement rod 78, preferably at the end remote from the engagement rod support 77.1. The guide element 78.2 may be formed as a protrusion on the engagement rod 78.

[0126] The supporting element 75 may further include a transmission element 76. Fig.19 As can be seen in the figure, the transmission element 76 can be formed as a protrusion on the support element 75. Preferably, the transmission element 76 is arranged in the end area of ​​the support element 75 facing away from the spring seat 73. The transmission element 76 can be guided on the counter transmission element 72 of the adjustment rod 70. As presented, the counter transmission element 72 can be a straight groove in the adjustment rod 70.

[0127] The adjustment lever 70 may have a bearing side 70.1, on which a lever bearing receiving portion 71.2 may be formed. The lever bearing receiving portion 71.2 may be designed as a hole. Facing away from the bearing side 70.1, the adjustment lever 70 may further have an operating side 70.2. Preferably, an operating surface 70.3 is arranged in the region of the operating side 70.2, on which the user can act.

[0128] As already explained, the adjusting lever 70 is pivotably mounted on the housing 9. For this purpose, a lever bearing projection 71.1 can be provided on the housing 9, in particular on the first housing half 10 (see Fig.21 ). Therefore, the rod support portion 71 may be formed by receiving the rod support protrusion 71.1 in the rod support portion receiving portion 71.2.

[0129] As mentioned above, the guide element 78.2 of the support element 75 can be guided on the guide rail 14. Fig.21 Here, for a better overview, Fig.21 Only the first housing half 10 and the engagement lever 78 are shown.

[0130] The guide rail 14 can be designed as a closed-loop rotating guide and has a tensioning section 14.1 and a return section 14.2. When the support element 75 moves relative to the housing 9, the guide rail 14 can define a movement trajectory B of the guide element 78.2. Fig.21 A movement of the bearing element 75 in a first adjustment direction S1 to the right may correspond to an increase in the preload of the spring element 65. A movement of the bearing element 75 in a second, opposite adjustment direction S2 may correspond to a reduction in the preload of the spring element 65.

[0131] The tensioning section 14.1 may include a first braking section 14.11, a second braking section 14.14 and a third braking section 14.18. The braking sections 14.11, 14.14, 14.18 may be configured such that the guide element 78.2 is held thereon against the second adjustment direction S2. Thus, if the guide element 78.2 moves into one of the braking sections 14.11, 14.14, 14.18, a movement of the support element 75 in the second adjustment direction S2 may be prevented.

[0132] Along the motion trajectory B, the first braking section 14.12 can be arranged between the first braking section 14.11 and the second braking section 14.14. In addition, the second deflection section 14.15 and the third deflection section 14.16 can be arranged between the second braking section 14.14 and the third braking section 14.18. The deflection sections 14.12, 14.15, 14.16 can cause a change in the movement direction of the guide element 78.2. For example, when the guide element 78.2 moves away from the first braking section 14.11, the guide element 78.2 can initially perform a movement in the first adjustment direction S1. In other words, the movement direction of the guide element 78.2 can initially correspond to the movement direction of the support element 75. At the deflection sections 14.12, 14.15, the guide element 78.2 can undergo a change in direction. In this case, the engagement lever 78 can pivot.

[0133] As in Fig.21 As can be further seen in the figure, the first intermediate braking section 14.13 can be arranged between the first deflection section 14.12 and the second braking section 14.14. In addition, the second intermediate braking section 14.17 can be arranged between the third deflection section 14.16 and the third braking section 14.18. The intermediate braking sections 14.13, 14.17 can be designed so that the guide element 78.2 is held thereon against the first adjustment direction S1. Therefore, if the guide element 78.2 moves into one of the intermediate braking sections 14.13, a movement of the support element 75 in the first adjustment direction S1 can be prevented.

[0134] Along the movement trajectory B, the third braking section 14.18 may be followed by the return section 14.2. For example, the third braking section 14.18 may be followed by the fourth deflection section 14.21. The fourth deflection section 14.21 may be followed by the return section 14.22. Finally, a fifth deflection section 14.23 may be provided, which may establish a connection of the return section 14.2 to the tensioning section 14.1, in particular to the first braking section 14.11.

[0135] like Fig.24 As can be seen in the figure, the device 1 may include a latch 80. The latch 80 may be mounted on the housing 9, preferably on the second housing half 20. For this purpose, a latch receiving portion 28 may be provided on the second housing half 20.

[0136] exist Fig.2580 is shown in more detail in FIG. The latch 80 can be an elastic and / or elastically deformable and / or displaceable element, which preferably has a base member 83. A spring section 82 can be connected to the base member 83. The spring section 82 preferably has an elastically resilient design. As shown in the figure, the spring section 82 can have a contour section of a meandering shape. In this way, elastic resiliency can be achieved with a flat design.

[0137] The spring section 82 may be followed by the support section 81. The support section 81 may preferably have a retaining projection 86.2. The retaining projection 86.2 may be retained (in particular latched) in a latch support receptacle 28.2 (see FIG. 2 ) in the region of the latch receptacle 28 of the second housing half 20. Fig.23 ). Therefore, the latch 80 can be supported on the housing 9 against the force in the direction from the base member 83 to the supporting section 81.

[0138] In addition, the latch 80 may have one or more displacement projections 86.3. Fig.25 As can be seen in FIG. 8 , the displacement projection 86.3 can preferably be arranged on the spring section 82 and the base member 83. The displacement projection 86.3 can be located in the displacement receiver 28.3 (see FIG. 24 ) in the region of the latch receiving portion 28. Fig.23 Preferably, the displacement receiver 28.3 is longer than the displacement protrusion 86.3, thereby ensuring the displaceability of the displacement protrusion 86.3.

[0139] Furthermore, a guide protrusion 86.1 may be provided on the base member 83, which may guide the receiving portion 28.1 in the region of the latch receiving portion 28 (see Fig.23 ) is guided.

[0140] from Fig.25 As can be seen in Figure 8 , the deflection surface 87 can be arranged on the base member 83. Via the deflection surface 87, a force can be introduced into the latch 80, which can lead to an elastic deformation of the latch 80 (preferably the spring section 82) in the direction of the bearing section 81. Preferably, the deflection surface 87 can be arranged on the spring protrusion 84. The spring protrusion 84 can be formed as an elastically deformable angled section on the base member 83. Therefore, in addition to the resilience of the spring section 82, the latch 80 also has resilience.

[0141] like Fig.24 As can be seen in the figure, the latch 80 can be arranged at least partially in the region of the guide track 12. Preferably, for this purpose, the guide track 12 can also be provided on the second housing half 20. Thus, the guide element 42 of the pivot lever 40 can be guided on the guide track 12 on the first housing half 10 and the second housing half 20.

[0142] Fig.24 The latch 80 is shown in an undeformed basic position. Here, the latch 80 can preferably bear with its deflection surface 87 against the guide track 12, in particular as shown in such a way that the swing-out section 12.3 is closed by the latch 80. However, due to the elastic deformability of the latch 80, the swing-out section 12.3 can be released when the guide element 42 moves from the ejection section 12.2 into the swing-out section 12.3.

[0143] Furthermore, a detent area 85 may be formed on the latch 80, preferably on the base member 83. The detent area 85 may be designed as a recess. Fig.24 As can be seen in the figure, the braking area 85 can cooperate with the guide rail 12 to at least partially form a second braking section 12.4 of the guide rail 12. Thus, after the guide element 42 has been displaced by the swing-out section 12.3, it can be held at the second braking section 12.4. A return to the swing-out section 12.3 can be prevented by the latch 80, because in this position the guide element 42 cannot exert a force component on the latch 80 that could displace it towards the support section 81.

[0144] In the following, an example of the operation of the device 1 will be explained in more detail with reference to the ejection and retraction operation of a movable furniture part.

[0145] exist Figure 2 In the figure, a first state is shown, in which the movable furniture part can be in a closed state and the drive 2 can be in contact with the drive stop 51. The carriage 30 is in a retracted position. The preload of the spring element 65 acts on the carriage 30 via the drive attachment 62 of the spring carriage 60.

[0146] The other driver stop 45 is pivoted away from the movement path of the driver 2. Likewise, the deflection surface 49.5 is pivoted away from the movement path of the driver 2.

[0147] The pusher 50 is in the rest position. The trigger 90 is in the blocking position. Here, the retainer attachment 98 protrudes into the guide track 12. The guide element 42 is located in the first braking section 12.1 and is retained on the retainer attachment 98 on the first braking section 12.1.

[0148] exist Fig.14 In FIG. 5 , another state is shown in which a force is exerted by the drive 2 on the drive stop 51. This can correspond to an overtravel exerted by the user on the movable furniture part. As a result, the pusher 50 is moved from its rest position to the adjustment position, overcoming the pretension of the spring 55. By the force transmission between the push surface 54.3 of the pusher 50 and the actuating surface 93 of the trigger 90, the trigger 90 is moved into the release position. In FIG. Fig.14, the trigger 90 moves to the left in the image plane, overcoming the pretension of the return spring 99. This moves the holder attachment 98 away from the guide track 12. As a result, the first braking section 12.1 is released and the guide element 42 can move into the ejection section 12.2.

[0149] Therefore, the trigger 90 and / or the retainer attachment 98 of the trigger 90 can also be interpreted as such a latch: it allows the pivot rod 40 to pivot from the pivot-out position to the pivot-in position, and prevents the pivot rod 40 from pivoting from the pivot-in position to the pivot-out position.

[0150] Furthermore, the movement of the trigger 90 causes the first synchronizing element 101 to rotate, and the rotation of the first synchronizing element 101 can be transmitted to the second synchronizing element 105 on the second device 1' through the synchronizing shaft 100. Therefore, the second coupling device 1' can also be triggered.

[0151] Fig.15 The carriage 30 is shown in the range of movement between the retracted position and the ejected position. The carriage 30 has moved while reducing the preload of the spring element 65. The guide element 42 is located in the ejection section 12.2. The other drive stop 45 is further pivoted away from the motion path of the drive 2. Fig.15 As can be seen further in the figure, the trigger 90 is moved back into its blocking position again by the pretension of the return spring 99. The pusher 50 is moved back into its rest position by the pretension of the spring 55. Via the drive stop 51, the movement of the carriage 30 is transmitted to the drive 2, whereby the movable furniture part is ejected.

[0152] Fig.16 The ejection position of the carriage 30 is shown. Advantageously, a plug 19 made of a flexible material can be provided on the housing 9, which can at least reduce the hard stop of the carriage 30 in the ejection position. After passing through the ejection section 12.2, the guide element 42 has been displaced along the pivoting-out section 12.3. The driver 2 is no longer located in the region of the further driver stop 45 and the deflection surface 49.5. Therefore, the driver 2 does block the pivoting-out of the pivoting lever 40.

[0153] according to Fig.16 , the guide element 42 is now located in the second braking section 12.4. Here, the guide element 42 elastically deforms the latch 80 during its displacement along the swing-out section 12.3 to briefly release the swing-out section 12.3. After the latch 80 is reset, the swing-out section 12.3 is blocked again and the guide element 42 is prevented from returning to the swing-out section 12.3. By the displacement of the guide element 42 at the swing-out section 12.3, the pivot lever 40 has been moved to the pivot-out position. Therefore, the other drive stop 45 is now in the movement trajectory of the drive 2.

[0154] The movable furniture part can now be ejected further by the momentum of the ejection movement and / or by manual extraction. This makes the drive 2 move further away from another drive stop 45 along its motion trajectory.

[0155] Fig.16 The ejection position shown in FIG. 4 may represent a waiting position for the device 1. If the movable furniture part is now moved again in the closing direction, the drive 2 encounters another drive stop 45, such as Fig.17 The pivot lever 40 is in the pivoted-out position and a further drive stop 45 is arranged in the movement path of the drive 2 .

[0156] When the movable furniture part is further acted upon, the carriage 30 is moved in the direction of the retracted position via contact between the drive 2 and the further drive stop 45. The preload of the spring element 65 increases. The guide element 42 leaves the second braking section 12.4 and is displaced along the retracted section 12.5.

[0157] according to Fig.18 , the guide element 42 has reached the screw-in section 12.6 after passing through the screw-in section 12.5. However, the pivot lever 40 is still in the pivoted-out position. Therefore, the other drive stop 45 is still in the movement trajectory of the drive 2. When a further force is applied by the drive 2 to the other drive stop 45, the guide element 42 is displaced along the screw-in section 12.6 and reaches the first braking section 12.1. Here, the deflection roller 45.1 can advantageously roll on the drive 2. Due to the design of the pivot lever 40, the force applied by the drive 2 is advantageously converted into a torque that contributes to the inner swing movement.

[0158] When the guide element 42 has reached the first braking section 12.1, the pivot lever 40 is in the pivoted-in position. As a result, the further drive stop 45 has been swung out of the movement path of the drive 2. The drive 2 can now move toward the drive stop 51, whereby the drive 2 is released from the force of the spring element 65. In other words, this results in the drive 2 running freely toward the end of the retraction movement.

[0159] It is conceivable to provide a retraction device which acts on the movable furniture part at least during free running and at least supports the completion of the retraction movement. Alternatively, the drive 2 can also be moved manually into the final closed position during free running.

[0160] When the driver 2 moves back to the vicinity of the driver stop 51, the Figure 2 Initial position shown.

[0161] In the following, an example of the operation of the adjustment of the preload of the spring element 65 is explained in more detail.

[0162] exist Figure 2 In FIG. 1 , a setting is shown which corresponds to a minimum pre-adjusted preload of the spring element 65 . Thus, the guide element 78 . 2 of the engagement lever 78 is located in the region of the first braking section 14 . 11 of the guide rail 14 .

[0163] To increase the preload, the user can now act on the actuating surface 70.3 of the adjusting lever 70 substantially in the first adjustment direction S1. This causes the adjusting lever 70 to pivot. Via the transmission element 76 of the support element 75 and the mating transmission element 72 of the adjusting lever 70, the pivoting of the adjusting lever 70 is converted into an adjustment of the support element 75. As a result, the support element 75 can be moved in the first adjustment direction S1.

[0164] Therefore, the guide element 78.2 initially also moves along the first adjustment direction S1 until it reaches the first deflection section 14.12. Here the guide element 78.2 is deflected toward the first intermediate braking section 14.13. When the guide element 78.2 reaches the area of ​​the first intermediate braking section 14.13, the guide element 78.2 remains in the area of ​​the first intermediate braking section 14.13 against the first adjustment direction S1. Therefore, the user faces resistance against further adjustment of the adjustment lever 70 in the first adjustment direction S1. When the user now finishes applying force to the operating surface 70.3, the guide element 78.2 can be moved into the second braking section 14.14 under the action of the force of the spring element 65. Therefore, with Figure 2 Compared to the situation shown in , the preload of the spring element 65 can be increased by one step. Therefore, the user receives tactile feedback that a higher level of preload has been reached.

[0165] In a similar manner, a further increased preload level can be achieved by the user acting again on the operating surface 70.3 of the adjusting lever 70. As a result, the guide element 78.2 can now be moved from the second braking section 14.14 via the second deflection section 14.15 and the third deflection section 14.16 into the second intermediate braking section 14.17. When the user stops applying force to the operating surface 70.3, the guide element 78.2 moves again from the second intermediate braking section 14.17 to the third braking section 14.18. The third stage of the adjustable pretension of the spring element 65 has thus been reached.

[0166] When a further force is applied to the operating surface 70.3, the guide element 78.2 can be displaced from the third braking section 14.18 into the range of the fourth deflection section 14.21. The guide element 78.2 thus enters the return section 14.2. Along the return section 14.2, the guide element 78.2 can initially move in the second adjustment direction S2, while reducing the pretension of the spring element 65. At the fifth deflection section 14.23, the guide element 78.2 can now return to the first braking section 14.11. Thus, the effect of the above-mentioned embodiment is once again achieved. Figure 2 The first stage of adjustable pre-tension is shown in .

[0167] In the following, a possible assembly process of the device 1 will be explained in more detail.

[0168] For example, the return spring 99 can first be connected to the spring bearing 16.4. Here, the first leg 99.1 is inserted into the spring holder 16.5. The second leg 99.2 can initially remain free. At the trigger 90, the damper can be inserted into the damper receiving portion 91.1. Now the trigger 90 can be inserted into the trigger receiving portion 16. Here, the second leg 99.2 of the return spring 99 can first be inserted into the supporting area 92.1 of the trigger 90. When the trigger 90 is inserted into the trigger receiving portion 16, the return spring 99 is also firmly held.

[0169] Furthermore, the spring carriage 60 can be inserted into the spring carriage guide 13. Here, the latch hooks 13.1, 13.2 can engage with the guide webs 64.1. Hereinafter, the spring element 65 can already be inserted into the spring bearing 63 of the spring carriage 60 on one side.

[0170] It is conceivable to subsequently preassemble the bearing element 75. Here, the engagement rod support extension 78.1 of the engagement rod 78 can be connected to the engagement rod support 77.1 of the bearing element 75. The preassembled bearing element 75 can then be inserted into the bearing element guide 15. Preferably, the guide element 78.2 is inserted into the first braking section 14.11 of the guide rail 14.

[0171] Now, the adjusting lever 70 and its lever bearing receptacle 71 . 2 can be placed on the lever bearing projection 71 . 1 of the housing 9 . In this case, the counter transmission element 72 of the adjusting lever 70 can be placed on the transmission element 76 of the bearing element 75 .

[0172] The spring element 65 can now be inserted into the spring seat 73 of the bearing element 75 .

[0173] In a next step, it is conceivable to pre-assemble the carriage 30 with the pusher 50 and the pivot lever 40. The deflection roller 45.1 can first be mounted on the pivot lever 40. Furthermore, the damper 47.2 can be inserted into the damper receiving portion 47.1. The pivot lever 40 can then be mounted on the pivot lever bearing attachment 37.1 of the carriage 30 via the pivot lever bearing area 41.

[0174] The pusher 50 can first be provided with a spring 55. For this purpose, the spring 55 can first be mounted with its second spring end 55.2 on the pin 54.1. Subsequently, the first spring end 55.1 can be supported on the spring support 53. Finally, the pusher 50 can be inserted into the pusher receiving part 36 of the carriage 30. Advantageously, the pusher 50 can be latched with its latching element 56 to the mating latching element 36.2 of the pusher receiving part 36.

[0175] Now, the carriage 30 can be inserted into the guide receiving parts 11.1, 11.2, 11.3, 11.4 by its protrusions 32.1, 32.2, 32.3. Here, the clamping attachment 38 of the carriage 30 can also engage with the transmission attachment 62 of the spring carriage 60. If necessary, the spring carriage 60 may need to be slightly displaced to overcome the pretension of the spring element 65.

[0176] When the carriage 30 is inserted, the pivot lever 40 can be in its pivoted-out position. Thus, the guide element 42 can be inserted into the retraction section 12.5 or the second braking section 12.4. Finally, the plug 19 can be inserted.

[0177] Now it is conceivable to insert the latch 80 into the latch receiving portion 28 in another step. To this end, the retaining projection 86.2 can first engage with the latch support receiving portion 28.2. Subsequently, the displacement projection 86.3 can engage with the displacement receiver 28.3.

[0178] If a device 1 having a first synchronizing element 101 and a trigger 90 and a second device 1 ′ having a second synchronizing element 105 and preferably a second trigger 90 ′ are provided, further assembly steps may differ between the first device 1 and the second device 1 ′.

[0179] The first device 1 can now be completed by connecting the first housing half 10 to the second housing half 20. Preferably, latching elements are provided on the first housing half 10 and the second housing half 20 for this purpose.

[0180] The first entraining element 101 can be inserted in a later step into the shaft opening 17 of the first device 1. For this purpose, the first entraining element 101 is inserted in such a way that the transmission element 102 is oriented so that it can engage with the second counterpart transmission element 96.

[0181] Preferably, the second synchronizing element 105 can be inserted into the second device 1' before the first housing half 10 and the second housing half 20 are connected. The retaining section 108 is retained at the retaining shoulder 17.2 of the shaft opening 17 of the second device 1'. The transmission element 106 of the second synchronizing element 105 engages with the first counterpart transmission element 95 of the second trigger 90'. It is now conceivable to complete the assembly of the second device 1' by connecting the first housing half 10 to the second housing half 20.

[0182] The first device 1 and the second device 1 ′ can now be mounted relative to each other on a movable furniture part or furniture body. If synchronization between the devices 1, 1 ′ is desired, the first synchronization element 101 can now first be inserted with its contour section 104 into the mating contour section 112.2 of the connecting part 110. The adapter 113 can be inserted with its contour section 114 into the opposite mating contour section 111.2 of the connecting part 110. Subsequently, the first synchronization element 101 can be inserted into the shaft opening 17 of the first device 1 in the above-described manner.

[0183] The adapter 113 with its coupling section 115 can now engage with the coupling section 109 of the second co-ordinating element 105 of the second device 1′. Advantageously, the coupling receptacle 115.1 is thereby placed on the coupling section 109 in a direction substantially perpendicular to the longitudinal axis of the second co-ordinating element 105. Thus, the coupling portion 115 of the adapter 113 can pass through the cutout 17.3 of the shaft opening 17.

[0184] As shown above, a device 1 for ejecting a movable furniture part is provided. The device 1 is designed to realize and / or support the ejection by force transmission between the device 1 and the drive 2.

In addition, the carriage 30 comprises a pivot rod 40, which can be pivoted between a pivot-in position and a pivot-out position.

In the ejection position or in the range of motion of the carriage 30 between the ejection position and the retracted position, the further drive stop 45 is pivoted away from the movement trajectory of the drive 2 in the pivot-in position.
