Description

Device for ejecting a movable furniture part

The invention relates to a device for ejecting a movable furniture part, wherein the device comprises a housing and a carriage movable relative to the housing, wherein the carriage is movable between a retracted position and an ejected position, wherein the carriage comprises a pivoted lever which is pivotable between a pivoted- in position and a pivoted-out position.

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. A pivotably mounted catch component is provided on the ejector. The catch component is guided by a guide pin on a guide track provided on the base plate. In an ejected position, the catch component is pivoted by the guide track into a pivoted- in position.

A disadvantage of the known device is that the catch component may undesirably move out of the pivoted-in position, for example move back into a pivoted-out or partially pivoted-out position. In particular, this may be the case if the movable furniture part, for example a drawer, is pulled out in a vigorous manner by a user. Accordingly, the catch component may be in an undefined position, which position may not correspond to a position required for safe and reliable operation of the device.

It is the object of the invention to provide a device of the type mentioned above, which offers increased safety and reliability in its function.

This object is achieved in that that a latch is provided, in that the latch permits pivoting of the pivoted lever from the pivoted-in position into the pivoted-out position and blocks pivoting of the pivoted lever from the pivoted-out position into the pivoted- in position or in that the latch permits pivoting of the pivoted lever from the pivoted- out position into the pivoted-in position and blocks pivoting of the pivoted lever from the pivoted-in position into the pivoted-out position. In this way, it may be prevented that the pivoted lever is unintentionally pivoted from the desired pivoted position. The pivoted lever is thus reliably positioned in the pivoted position required for the safe and reliable function of the device. Preferably, the pivoted lever may be in the ejected-out position in the pivoted-out position.

It is conceivable that the device is provided on a furniture body, and that a driver is provided on the movable furniture part. A transmission of force may be intended between the carriage and the driver in order to cause and/or support the ejection of the movable furniture part. It is also conceivable that the driver is provided on the furniture body and the device is provided on the movable furniture part. A movable furniture part may, for example, be a drawer. More than one device may also be provided. Particularly in the case of wider drawers, it makes sense to provide two devices, for example on both sides of the drawer.

According to an advantageous embodiment of the invention, it is proposed that the pivoted lever is pivoted into the pivoted-out position in the ejected position or in a range of movement of the carriage between the retracted position and the ejected position, preferably the pivoted lever is pivoted into the pivoted-in position in the retracted position or in a range of movement of the carriage between the ejected position and the retracted position.

It is conceivable, for example, that the pivoted lever comprises a driver stop that is arranged, in the ejected position, in the motion trajectory of a driver. The ejected position may represent a waiting position when, for example, the movable furniture part is ejected. Here, the movable furniture part may be in an opening or partial opening position. When the movable furniture part is moved towards a closed position, the driver hits the driver stop on the pivoted lever, since the driver stop is, in the ejected position, located in the motion trajectory of the driver. Hence, it is ensured that the driver stop is reliably positioned in the motion trajectory of the driver when the carriage is in the ejected position.

Of course, it is also conceivable that the pivoted lever is pivoted into the pivoted-in position in the ejected position or in a range of movement of the carriage between the retracted position and the ejected position. In this case, the pivoted lever may preferably be pivoted into the pivoted-out position in the retracted position or in a range of movement of the carriage between the ejected position and the retracted position.

If it is provided that the housing comprises a first housing half and a second housing half, that one housing half comprises a latch receptacle, and that the latch is receivable in the latch receptacle, the latch may be accommodated in a space-saving manner. It is conceivable that only one half of the housing comprises a latch receptacle. In this case, for example, only one latch may be provided. However, it is also conceivable that both housing halves comprise a latch receptacle. In this case, two latches may be provided.

One variant of the invention may be such that a guide element is provided on the pivoted lever, that a guide track is provided on the housing, that the guide element is guided in the guide track, that the guide track comprises a swivel-out section and that the pivoted lever can be pivoted from the pivoted-in position to the pivoted-out position by a displacement of the guide element along the swivel-out section.

With a guide track, the movement of the carriage can be easily translated into a pivoting movement of the pivoted lever. For example, pivoting of the pivoted lever may be achieved during moving of the carriagein the retracted position or in a range of movement between the retracted position and the ejected position.

The guide track may be formed by the housing, in particular be provided integrally thereon. However, it is also conceivable that the guide track is formed by another part of the device, in particular as an individual part which is accommodated on the housing, for example. If the housing is divided, for example comprises two housing halves, the guide track may be provided on one or on both housing halves, in particular formed integrally by each of them or received on each of them. In this way, the guide element is securely guided.

If it is further provided that the guide track is designed as a closed-loop revolving guide and comprises an ejection section and a retraction section, that the guide element, at the ejection section, is guided in the ejection direction toward the ejected position, that the guide element, in the retraction section, is guided in the opposite direction thereto, and in that the swivel-out section connects the ejection section to the retraction section in the region of the ejected position, defined guidance of the pivoted lever may be ensured in all operating states of the device. In particular, a precise pivoting out and in of the pivoted lever may be achieved.

Accordingly, it is also conceivable that the guide track comprises a swivel-in section, and that the pivoted lever can be pivoted from the pivoted-in position to the pivoted- out position by displacing the guide element along the swivel-in section.

According to the invention, it may be provided that a spring element with a spring section is assigned to the latch, that the latch is held in the region of the swivel-out section elastically and/or deformably against the force of the spring element, that, during a pivoting of the pivoted lever from the pivoted-in position to the pivoted-out position, the guide element exerts a force on the latch, and that, as a result of the force exerted, the latch can be moved at least partially out of the region of the swivel- out section against the force of the spring element.

Thus, pivoting of the pivoted lever from the pivoted-in position to the pivoted-out position may be used to achieve an at least partial displacement of the latch. In this way, the pivoting of the pivoted lever in a desired direction, in particular from the pivoted-in to the pivoted-out position, may be permitted particularly easily. After the desired pivoting of the pivoted lever, the latch may be returned to the swivel-out section by the force of the spring element. Thus, by simple means an undesired pivoting of the pivoted lever from the pivoted-out position is prevented.

Alternatively or additionally, it is conceivable that the latch is held in the region of the of a swivel-in section elastically displaceably and/or deformably against the force of the spring element, that during pivoting of the pivoted lever from the pivoted-out to the pivoted-in position, the guide element exerts a force on the latch, and that due to the exerted force, the latch can be moved at least partially out of the region of the swivel-in section against the force of the spring element. In this way, the above- mentioned advantages can also be achieved with regard to undesired pivoting of the pivoted lever from the pivoted-in position. According to an advantageous further aspect of the invention, it is proposed that the latch is designed as an elastic component. In this case, an additional spring element may be dispensed with. A space-saving design of the latch may result in particular if the latch comprises the/a spring section, wherein the spring section is preferably flat. In particular, when the device is used with a drawer, a flat design of the device may be desirable. A device of flat design may be mounted below a drawer, for example, in order to save space. Sufficient elasticity and/or compliance of the spring section may preferably be achieved in a flat design by the spring section being formed by a wave-, meander- or zigzag-shaped profile section. In this case, a spring constant of the spring section adapted to an application purpose may be specifically provided by the design of the profile section.

The displaceability and/or deformability of the latch may be easily achieved and/or supported by the latch being supported, with one of its ends, on the housing. In particular, the latch may be supported, on one end, on the housing, whereby a fixed bearing may be provided, i.e. no play may be provided between the supported end of the latch and the housing. It is, on the other hand, also conceivable to provide a clearance within of the support of the latch relative to the housing so as to allow for a limited degree of movement of the supported end of the latch relative to the housing.

A structurally simple and reliable support and/or bearing of the latch can be achieved if the latch comprises a bearing section, the bearing section preferably comprising at least one retaining projection, the retaining projection being secured to a latch bearing receptacle of the housing. Of course, several retaining projections and latch bearing receptacles are also conceivable. In particular, if the retaining projection is latched to the latch bearing receptacle, this results in a detachable but secure connection to the housing. This may also facilitate assembly of the device.

An advantageous embodiment of the invention may be characterized in that the latch is at least partially movable relative to the housing by means of a sliding guide, wherein the sliding guide comprises at least one displacement receiver in which at least one displacement projection is displaceable along a displacement direction and in that the displacement projection is secured to the displacement receiver perpendicular to the displacement direction, in particular is releasably secured, preferably is latchable the displacement receiver. It is conceivable that exactly one, several or all connections between displacement receivers and displacement projections can be latched. Displacement receivers may be provided on the housing, and displacement projections on the latch. Conversely, it is also conceivable that displacement receivers are provided on the latch, and displacement projections are provided on the housing.

Undesirable noise development and/or undesirable wear of the latch and/or the pivoted lever and/or other components of the device may be prevented or at least reduced by the latch comprising a base member to which a spring projection is coupled, in that the spring projection is elastically deflectable relative to the base member and is designed to be at least partially in contact with the pivoted lever when the pivoted lever pivots out, in particular to be at least partially in contact with the/a guide element of the pivoted lever. The contact area between the latch and the pivoted lever may thus be designed to be resilient.

One embodiment of the invention may be such that the latch comprises a deflection surface, and that the deflection surface forms part of the/a guide track during pivoting of the pivoted lever. This results in a compact design. In particular, because the latch is displaceable and/or deformable, if the deflection surface forms part of the guide track, an adjustable region of the guide track may be achieved. It may be provided that the deflection surface forms part of a/the swivel-out section of the guide track. Thus, the latch may be at least partially displaced when the pivoted lever is pivoted, in particular when the pivoted lever is pivoted by means of the swivel-out section. If it is further provided that the deflection surface is provided on the/a spring projection of the latch, a noise and/or wear reduction may be achieved when the pivoted lever meets and/or is displaced at the swivel-out section.

Of course, it is also conceivable that the deflection surface forms part of the/a guide track during the pivoting-in of the pivoted lever. Accordingly, it may be provided in particular that the deflection surface forms part of a/the swivel-in section of the guide track. Thus, the mentioned advantages may also be achieved when the pivoted lever is pivoted in. The pivoted lever may be securely held in a pivoted-out position if it is provided that the latch comprises a detent area, that the detent area in at least one pivoted-out position of the pivoted lever at least partially forms a detent position of the pivoted lever, in particular at least partially forms a detent position of a/the guide element of the pivoted lever. In this case, it may be provided in particular that the/a guide track comprises a detent section, and that the detent position of the pivoted lever is formed by the detent section of the guide track and the detent area of the latch.

Of course, it may also be provided that the pivoted lever can be held securely in a pivoted-in position if, for example, it is provided that the guide track comprises a detent section corresponding to a pivoted-in position of the pivoted lever, and the detent position of the pivoted lever is formed by the detent section of the guide track and the detent region of the latch.

Smooth and reliable guidance of the latch may be achieved by the latch comprising the/a base member, and by the latch being guided with its base member on the housing at least in regions.

According to a preferred embodiment of the invention, it is proposed that the spring projection is provided on one side of the/a base member of the latch, wherein the/a spring section is preferably provided on the latch opposite the spring projection and adjoining the base member, wherein the/a bearing section is further preferably provided adjoining the spring section.

Figure 1 shows a schematic exploded view of a device 1 . As can be seen from the figure, the device 1 may have a housing 9, which may comprise a first housing half 10 and a second housing half 20. Figure 2 shows a schematic top view of the device 1 , wherein the second housing half 20 is not shown. For example, this may correspond to a situation in which the second housing half 20 has been removed. As can be seen from Figures 1 and 2, the device 1 may comprise a carriage 30 which may be mounted movably relative to the housing 9. The carriage 30 may include a driver stop 51. The driver 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.

As further shown in Figures 1 and 2, the device 1 may further comprise a pivoted lever 40. The pivoted lever 40 may be pivotally mounted to the carriage 30. A further driver stop 45 may be provided on the pivoted lever 40. The pivoted lever 40 may include a guide element 42, which may be configured as a guide pin. Furthermore, a deflector 49 may be provided. The deflector 49 may be pivotably and/or displaceably mounted on the carriage 30, on the one hand, and pivotably and/or displaceably mounted on the pivoted lever 40, on the other hand.

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

It may be further understood from Figures 1 and 2 that the device 1 may comprise a spring element 65. The spring element 65 may comprise two extension springs, in particular helical springs. The spring element 65 may be mounted on a spring carriage 60 on one side. The spring carriage 60 may be mounted on the housing 9 so as to bemovable, in particular linearly displaceable.

The spring carriage 60 may have a transmission attachment 62. A force may be transmitted between the transmission attachment 62 and a clamp attachment 38 (see Fig. 4) of the carriage 30.

On a side of the spring element 65 opposite the spring carriage 60, the spring element 65 may be supported on a bearing element 75. The bearing element 75 may be movable relative to the housing 9. Thus, a preload of the spring element 65 may be modifiable. As can be seen from Figure 2, an adjustment lever 70 may be provided for adjusting the bearing element 75. The adjustment lever 70 may, for example, be pivotably mounted on the housing 9. As can be seen in Figures 1 , 2 and 22, the device 1 may comprise a first synchronizing element 101 or a second synchronizing element 105. The synchronizing elements 101 , 105 will be further discussed elsewhere herein.

Figure 3 shows a schematic top view of a first housing half 10. As can be seen from the figure, the first housing half 10 may comprise guide receptacles 11.1 , 11 .2, 11 .3, 11.4. The guide receptacles 11.1 , 11.2, 11.3, 11.4 may serve to guide the carriage 30. For this purpose, projections 32.1 , 32.2, 32.3 may be provided on the carriage 30, as can be clearly seen in Figure 6. The projections 32.1 , 32.2, 32.3 may, for example, be guided in the guide receptacles 11.1 , 11.2, 11.3, 11.4. In particular, the guide receptacles 11.1 , 11 .2, 11 .3, 11 .4 may be designed as guide tracks.

As can be seen further from Figure 3, a guide track 12 may further be provided on the first housing half 10. The guide track 12 may serve to guide the pivoted lever 40. For example, as shown in Figure 7, the pivoted 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.

Furthermore, it can be seen in Figure 3 that the first housing half 10 may have a spring carriage guide 13. The spring carriage 60 may be guided on the spring carriage guide 13 in a linearly movable manner. In particular, the spring carriage 60 may be latched to the spring carriage guide 13. For this purpose, latching hooks

13.1 , 13.2 may be provided on the spring carriage guide 13, for example. As can be seen from Figures 19 and 20, the spring carriage 60 may have guide webs 64.1 ,

64.2. The guide webs 64.1 , 64.2 may, for example, be engaged behind by the latching hooks 13.1 , 13.2.

Furthermore, the first housing half 10 may comprise a bearing element guide 15. The bearing element 75 may be guided at the bearing element guide 15. In particular, the bearing element 75 may be guided on walls 15.1 , 15.2 of the bearing element guide 15. Movability of the bearing element 75 relative to the housing 9 may be limited, for example, by stops 15.3, 15.4 being provided on the bearing element guide 15. In the area of the bearing element guide 15, a guideway 14 may also be provided on the first housing half 10, as further shown in Figure 3. The guideway 14 may serve to guide a guide element 78.2 of the bearing element 75 (see Figure 20).

The first housing half 10 may include a trigger receptacle 16, as further shown in Figure 3. The trigger receptacle 16 may serve to receive the trigger 90. As can be seen in Figures 11 and 12, the trigger 90 may include a first arm portion 91 and a second arm portion 92. The arm sections 91 , 92 may be arranged at right angles to each other, for example. The second arm portion 92 may include an activation surface 93. As can be seen in Figure 3, the trigger receptacle 16 may have an arm opening 16.2 through which the second arm portion 92 may protrude at least partially from the housing 9. Thus, the activation surface 93 becomes accessible from outside the housing.

At the first arm section 91 , the trigger 90 may comprise the retainer attachment 98. The trigger receptacle 16 may have a retainer aperture 16.1 , which may be used to connect to a guide track 12. The guide track 12 will be discussed in more detail elsewhere herein. The retainer attachment 98 may be guided through the retainer aperture 16.1 into the region of the guide track 12. Preferably, a damper receptacle 91.1 is provided in the region of the retainer attachment 98 on the trigger 90, in which a damper may be received. The damper may preferably be made of a soft and/or damping material.

The trigger 90 may be movably mounted on the housing 9. In particular, the trigger 90 may rest with a rear side 97 (see Figure 12) against a bottom 16.6 of the trigger receptacle 16. Furthermore, a guide web 16.3 may be provided on the trigger receptacle 16, which may engage in a recess 97.1 of the trigger 90 (see Figure 12).

As can be further seen in Figure 3, a spring bearing 16.4 may be provided on the first housing half 10. The return spring 99 may be held on the spring bearing 16.4. For example, the return spring 99 may be a torsion spring. The return spring 99 may counteract an displacement of the trigger 90. The trigger receptacle 16 may include a spring retainer 16.5, to which a first leg 99.1 of the return spring 99 may be retained. A second leg 99.2 may, for example, be supported on a support area 92.1 of the trigger 90 (see Figure 11 ).

Figure 3 shows that the first housing half 10 may have a shaft opening 17. The shaft opening 17 may receive the synchronizing element 101 , 105. For example, a synchronizing element 101 , 105 may be inserted or positioned in the shaft opening 17. The shaft opening 17 may have a neck 17.1 against which an abutment portion 103, 107 of the synchronizing element 101 , 105 may bear in a rotationally supported manner.

Furthermore, a cutout 17.3 may be provided in the region of the shaft opening 17, as shown in Figure 23. Preferably, the cutout 17.3 may be provided at the first housing half 10. The cutout 17.3 may represent an opening in the housing wall. Through the cutout 17.3, a part of the shaft opening 17 may be accessible from a direction transverse to a 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.

As has already been mentioned, a guide track 12 may be provided on the first housing half 10. The guide element 42 of the pivoted lever 40 (see Figure 4) may be guided in the guide track 12. The guide track 12 may be designed as a closed-loop revolving guide. A direction of revolution may correspond to the clockwise direction in Figure 3. The guide track 12 may have a first detent section 12.1 and a second detent section 12.4. Between the first detent section 12.1 and the second detent section 12.4, the guide track 12 may have an ejection section 12.2 and a swivel-out section 12.3 in the direction of revolution. Between the second detent section 12.4 and the first detent section 12.1 , the guide track 12 may have a retraction section 12.5 and a swivel-in section 12.6.

The pivoted lever 40 is shown in more detail in Figures 7 and 8. The pivoted lever 40 may have an arm section 40.1 , which is angularly adjoined by a bent section 40.2. A pivoted lever bearing area 41 may be provided on the arm section 40.1. The pivoted lever bearing area 41 may be in the form of a bore, as shown herein. A pivoted lever detent region 41.1 may be provided in the area of one side of the pivoted lever 40, presently in the area of the pivoted lever lower side 40.4. The pivoted lever detent region 41.1 may, for example, form a surface region set back relative to the pivoted lever lower side 40.4.

The further driver stop 45 may be provided at the bent section 40.2. The further driver stop 45 may be provided as a deflection roller 45.1 , which may be rotatably mounted on the pivoted lever 40. Preferably, the deflection roller 45.1 may be made of a soft and/or damping material.

As can be seen further from Figure 7, a deflection attachment 46 may be provided in the region of the further driver stop 45. The deflection attachment 46 may project beyond the pivoted lever 40 in its thickness, for example in such a way that the deflection attachment 46 projects beyond the pivoted lever upper side 40.3 and/or beyond the pivoted lever lower side 40.4. On a side facing away from the pivoted lever 40, the deflection attachment 46 may include a deflection surface 46.1 .

The guide element 42 may be provided on the pivoted lever 40. Preferably, the guide element 42 may be arranged in the transition region between the arm section 40.1 and the bent section 40.2. The guide element 42 may, for example, be pin-shaped. As can be seen from Figures 7 and 8, the guide element 42 may project beyond the pivoted lever upper side 40.3 and the pivoted lever lower side 40.4. A guide projection 42.1 may also be provided in the region of the guide element 42. The guide projection 42.1 may have a larger outer diameter than the guide element 42. Preferably, the guide projection 42.1 is arranged concentrically with the guide element 42. The guide projection 42.1 may project less far beyond the pivoted lever upper side 40.3 and/or the pivoted lever lower side 40.4 than the guide element 42.

As Figure 7 further shows, a guide protrusion 48 may be formed on the pivoted lever upper side 40.3. The guide protrusion 48 may protrude beyond the pivoted lever upper side 40.3. Further, a damper 47.2 may be held on the pivoted lever 40, for example in a damper receptacle 47.1 . The damper 47.2 may preferably be made of a soft and/or damping material. The pivoted lever 40 may further comprise a deflector receptacle 44, for example as present in the form of a recess. Preferably, the deflector receptacle 44 is formed in the region of the bent section 40.2. As can be seen in particular in Figure 8, the deflector receptacle 44 may have laterally undercut rib receptacles 44.1 .

As can be seen in Figure 6, a pivoted lever bearing attachment 37.1 may be provided on the carriage 30. This may be a cylindrical projection. Furthermore, a latching element 37.2 may be provided in the area of the pivoted lever bearing attachment 37.1 . The latching element 37.2 may, for example, be formed as a latching lug.

The carriage 30 may further comprise a guide track 34. Preferably, the guide track 34 may be configured as an arcuate slot through the carriage 30. Furthermore, a guide recess 37 may also be formed on the carriage 30. Preferably, guide track 34 and/or guide recess 37 may be circular arc-shaped, with pivoted lever bearing attachment

37.1 forming the center of the circular arc.

As can be seen in Figure 4, the pivoted lever 40 may be pivotally mounted on the carriage 30 in that the pivoted lever bearing attachment 37.1 of the carriage 30 is received in the pivoted lever bearing area 41 of the pivoted lever 40. Here, the pivoted lever 40 may be retained on the carriage 30 by latching the latching element

37.2 to the pivoted lever detent region 41 .1 .

As shown herein, the pivoted lever 40 may be inserted into a recess that may be formed in the region of the carriage underside 30.2 of the carriage 30. The guide element 42 may project beyond the carriage 30 at its carriage underside 30.2. Also, the guide element 42 may extend through the guide track 34 so that it also overhangs the carriage 30 at its carriage upper side 30.1. The guide projection 42.1 may preferably be guided on the guide track 34. The guide protrusion 48 of the pivoted lever 40 may be guided on the guide recess 37 of the carriage 30.

Figure 4 further shows that the deflector 49 may be mounted in the deflector receptacle 44 of the pivoted lever 40 with a projection 49.2. As can be seen in Figure 9, the deflector 49 may have extension ribs 49.3 laterally and offset in the region of the projection 49.2. The extension ribs 49.3 may be received in the projections 44.1 of the deflector receptacle 44 of the pivoted lever 40.

As Figure 9 further shows, the deflector 49 may have a deflector bearing receptacle

49.1 in an end region facing away from the projection 49.2. The deflector bearing receptacle 49.1 may be a bore, as shown here. A deflector ledge 49.4 may be formed on one side of the deflector 49 along its longitudinal extent. The deflector ledge 49.4 may form a deflecting surface 49.5.

The deflector 49 may be pivotably mounted on the carriage 30. For this purpose, a deflector bearing area 39 may be provided on the carriage 30, as can be seen in Figure 6. The deflector bearing area 39 may be formed as a projection, for example a cylindrical projection. The deflector bearing area 39 may be received in the deflector bearing receptacle 49.1 to form a pivot bearing.

As can be further seen in Figure 4, a pusher 50 may be provided on the carriage 30. The pusher 50 may form the driver stop 51 . The pusher 50 may be received in a pusher receptacle 36 of the carriage 30. The pusher receptacle 36 is shown in more detail in Figure 5. Accordingly, the pusher receptacle 36 may have a receiving space

36.1 in which the pusher 50 may be at least partially received.

In a region of the pusher receptacle 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 comparably formed abutment surface 36.3 may be provided opposite. Furthermore, the pusher receptacle 36 may have counter latching elements 36.2 in the region of the receiving space 36.1 , which may be formed as recesses and/or apertures as shown.

A possible design of the pusher 50 may be taken from Figure 10. The pusher 50 may have a spring bearing 53 and a spring abutment 54. A spring 55 may be arranged between the spring bearing 53 and the spring abutment 54. The spring 55 may be a compression spring, for example a helical spring. As can be seen in Figure 10, the spring 55 may be supported by a first spring end 55.1 on the spring bearing 53. Here, it is conceivable that a retaining projection 53.1 is provided on the spring bearing 53. For example, the retaining projection 53.1 may be designed as a latching element that can be latched to the first spring end 55.1 .

The spring abutment 54 may have a transverse extension 54.2 which is less than a transverse extension, in particular an outer diameter of the spring 55 in the region of the second spring end 55.2. As can be seen from Figure 10a, the spring may consequently project laterally beyond the spring abutment 54.

In the area of the driver stop 51 , the pusher 50 may have an actuating surface 51.1 on which a driver 2 can act. A pushing surface 54.3 may be formed at an end of the pusher 50 facing away from the driver stop 51 , in particular at the spring abutment 54. Furthermore, a counter-support surface 51.2 facing the driver stop 51 may be provided on the spring bearing 53. The pusher 50 may further comprise latching elements 56, as can be seen more clearly in Figure 10b.

In an installed state (see Figure 4), the latching elements 56 of the pusher 50 may be latched with the counter latching elements 36.2 of the carriage 30. In this case, the latching elements 56 and the counter latching elements 36.2 may be designed to ensure movability, particularly linear movability of the pusher 50.

The second spring end 55.2 of the spring 55 of the pusher 50 may come to rest against the abutment surface 36.3 of the pusher receptacle 36 of the carriage 30. In particular, the portions of the second spring end 55.2 projecting beyond the spring abutment 54 may bear against the abutment surface 36.3. The counter-support surface 51 .2 of the pusher 50 may bear against the support surface 36.4.

Figure 23 shows an arrangement of a device 1 and a second device T which are connected to each other by means of a synchronizing shaft 100. An embodiment of the synchronizing shaft 100 is illustrated in Figure 22 by means of an exploded view. Accordingly, the synchronizing shaft 100 may be made of several parts. In particular, the synchronizing shaft 100 may comprise a first synchronizing element 101 and a second synchronizing element 105, which are connected to each other in a rotationally fixed manner via a connecting part 110. The synchronizing elements 101 , 105 may each be formed as a shaft. Radially projecting transmission elements 102, 106 may be provided on the synchronizer elements 101 , 105. As shown in Figure 22, the transmission elements 102, 106 may be designed as individual circumferentially limited projections extending along at least part 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, toothing may also be conceivable.

Furthermore, the synchronizing elements 101 , 105 may have abutment portions 103, 107, which may, for example, be formed as shoulders. Further, the second synchronizing element 105 may also have a retaining section 108, which may also be formed as a shoulder.

The first synchronizing element 101 may have a profile section 104 in an end region thereof. As illustrated herein, for example, a T-section may be selected. Latching elements 104.1 may further be provided in the region of the profile section 104.

Deviating therefrom, the second synchronizing element 105 may comprise a coupling section 109 in an end region. The coupling section 109 may, for example, be formed by two surfaces formed parallel to each other and parallel to the longitudinal axis of the second synchronizing element 105. Latching elements 109.1 may be provided on the surfaces of the coupling section 109, which may be formed as recesses, for example.

A connection of the second synchronizing element 105 to the connecting part 110 may be achievable by means of an adapter 113. In this regard, the adapter 113 may comprise a coupling portion 115 having a coupling receptacle 115.1. The coupling receptacle 115.1 may be formed to correspond to the coupling section 109 of the second synchronizing element 105. The coupling receptacle 115.1 may form a coupling section 109 receiving area open in the radial direction on one side. Counter latching elements 115.2 may be formed within the coupling receptacle 115.1. By means of latching the latching elements 109.1 with the counter latching elements 115.2, the adapter 113 may be fixed in radial direction to the second synchronizing element 105.

A profile section 114 may be provided at an end of the adapter 113 facing away from the coupling portion 115. The profile section 114 may advantageously be formed similar to the profile section 104 of the first synchronizing element 101 .

The connecting part 110 may be, for example, a cut-to-length section of a bar material or a profile. In its end regions 112, 113, the connecting part 110 may have counter profile sections 111.2, 112.2 on both sides. The counter profile sections 111.2, 112.2 may be formed as recesses in end surfaces 111.1 , 112.1 provided at the end regions 112, 113. In particular, the counter profile sections 111.2, 112.2 may be formed to correspond to the profile sections 104, 114. Accordingly, the counter profile sections 111.2, 112.2 may be formed as T -shaped recesses in the longitudinal end surfaces 111.1 , 112.1 of the connecting part 110. Conceivably, but not necessarily, that the counter profile sections 111 .2, 112.2 may have counter latching elements corresponding to the latching elements 104.1 , 114.1. Alternatively or additionally, the latching elements 104.1 , 114.1 may also be used to achieve elastic bracing against the walls of the counter profile sections 111.2, 112.2.

Figure 13 shows sections of devices 1 , T with inserted synchronizing elements 101 , 105. As can be seen from Figure 13a, the first synchronizing element 101 may be inserted in the shaft opening 17 of a device 1 , for example a first device 1 . Thereby, the abutment portion 103 of the first synchronizing element 101 may be supported at the neck 17.1 of the shaft opening 17.

As can be seen from Figure 13b, the second synchronizing element 105 may be inserted into the shaft opening 17 of a second device T. Again, the abutment portion 107 may be supported at the neck 17.1. Furthermore, the retaining section 108 may be supported on the retaining shoulder 17.2 of the shaft opening 17. Accordingly, the second synchronizing element 105 may be held securely in the shaft opening 17 along its longitudinal axis in both directions. In contrast, the first synchronizing element 101 may be retained in only one direction such that it may be inserted into the shaft opening 17 when the housing 9 is closed, particularly when the first housing half 10 and the second housing half 20 are assembled.

The coupling section 109 may be disposed in a region of the cutout 17.3 of the shaft opening 17. Accordingly, the adapter 113 may be enabled to be coupled to the second synchronizing element 105 from a direction transverse to the longitudinal axis thereof. In particular, the adapter 113 may be guidable with its coupling portion 115 through the cutout 17.3 onto the coupling portion 109 of the second synchronizing element 105.

The trigger 90 may comprise a first transmission counter element 95 and a second transmission counter element 96, as can be seen in Figures 11 and 12. The transmission counter elements 95, 96 may be provided as recesses formed to correspond to the transmission elements 102, 106. The transmission counter elements 95, 96 may preferably be diametrically opposite each other with respect to the longitudinal axis of the synchronizing elements 101 , 105. In particular, it may be provided that the second transmission counter element 96 is provided on an extension piece 94, which may be provided in a transition region between the first arm portion 91 and the second arm portion 92 of the trigger 90.

Figure 13a shows a first synchronizing element 101 having its transmission element 102 engaged with the second transmission counter element 96 of the trigger 90. Accordingly, the transmission element 102 is oriented to face out of the image plane. A leftward displacement of the trigger 90 in the image plane may correspond to a triggering movement. A movement of the trigger 90 to the left may cause a movement of the transmission element 102 to the left and, accordingly, a rotation of the first synchronizing element 101 about its longitudinal axis.

In contrast, Figure 13b shows a second synchronizing element 101 having its transmission element 106 engaged with the first transmission counter element 95 of a second trigger 90' of the second device T. The second trigger 90' may be configured in the same way as the trigger 90, but preferably the second trigger 90' does not comprise an extension piece 94. Accordingly, it may be provided that the second trigger 90' comprises only a first transmission counter element 95. In Figure 13b, the transmission element 106 is oriented to face into the image plane. An movement of the second trigger 90' to the left in the image plane may also correspond to a triggering movement. An movement of the second trigger 90' to the left may cause an movement of the transmission element 106 to the left. However, since the transmission element 106 now points into the image plane, in contrast to the situation shown in Figure 13a, this results in a direction of rotation of the second synchronizing element 105 which is opposite to that of the first synchronizing element 101.

If two devices 1 , 1 ' are now arranged opposite each other in a typical installation situation as shown in Figure 23, this results in a uniform direction of rotation of the synchronizing shaft 100, which is coupled in a rotationally fixed manner to the synchronizing elements 101 , 105, during a triggering movement of the two triggers 90, 90'. Accordingly, there is no need to provide a second device 1 ' which is mirror- inverted with respect to the first device 1. Rather, two devices 1 , 1 ' of at least predominantly identical design may be synchronized with one another. Preferably, only two differently designed synchronizing elements 101 , 105 need to be used for this purpose. Preferably, but not necessarily, two differently designed triggers 90, 90' may also be used.

Figures 19 and 20 show the spring carriage 60, the spring element 65, the bearing element 75 and the adjustment lever 70 in more detail. As can be seen from the figures, the spring element 65 may comprise one or at least two extension springs 65.1. The extension springs 65.1 may have narrowed regions 65.3 at their respective ends. Head regions 65.4 may adjoin the narrowed regions 65.3, wherein the head regions 65.4 may have an enlarged outer diameter compared to the narrowed regions 65.3.

Spring bearings 63 may be provided on the spring carriage 60 to accommodate the 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 bounded 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.

The spring bearing 63 may be formed as recesses in the rear wall 61.3 corresponding to the narrowed regions 65.3. Preferably, the recesses are open facing away from the bottom 64. Thus, the narrowed regions 65.3 may be easily inserted into the recesses. In Figure 19, the spring element 65 is not inserted into the spring bearing 63 for better visibility of the spring bearing 63.

In the area of the end of the spring carriage 60 opposite the rear wall 61.3, the transmission attachment 62 may be arranged. As can be seen from the figures, a counter stop surface 62.1 may be formed on the transmission attachment 62. The counter stop surface 62.1 may be in contact with a stop surface 38.1 of the clamp attachment 38 of the carriage 30 (see Figure 5).

Opposite the spring carriage 60, the spring element 65 may be mounted on the bearing element 75. For this purpose, spring mounts 73 may be provided, which preferably are designed in a comparable manner to the spring mounts 63 of the spring carriage 60.

As can be seen further from Figures 19 and 20, the engaging lever 78 may be pivotably mounted on the bearing element 75. For this purpose, an engaging lever bearing 77.1 may be provided on the bearing element 75. For example, the engaging lever bearing 77.1 may be configured as a bore. The engaging lever 78 may have an engaging lever bearing extension 78.1 in an end region, which may be held in the engaging lever bearing 77.1. Preferably, latching elements 75.4 may be provided on the bearing element 75 in the region of the latching lever bearing 77.1. The latching elements 75.4 may, for example, act on a surface on the latching lever 78 in such a way that the latter may be held securely on the latching lever bearing 77.1 .

The engaging lever 78 may be received on the bearing element 75 in an engaging lever recess 75.5. The engaging lever recess 75.5 may, in particular, be formed as an aperture and frame a pivot region of the engaging lever 78. A guide element 78.2 may be provided on the engaging lever 78, preferably at an end facing away from the engaging lever bearing 77.1. The guide element 78.2 may be formed as a projection on the engaging lever 78.

The bearing element 75 may further comprise a transmission element 76. As can be seen in Figure 19, the transmission element 76 may be formed as a projection on the bearing element 75. Preferably, the transmission element 76 is provided in an end region of the bearing element 75 facing away from the spring mount 73. The transmission element 76 may be guided on a counter transmission element 72 of the adjustment lever 70. As present, the counter transmission element 72 may be a straight slot in the adjustment lever 70.

The adjustment lever 70 may have a bearing side 70.1 on which a lever bearing receptacle 71.2 may be formed. The lever bearing receptacle 71.2 may be designed as a bore. 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 provided in the region of the operating side 70.2, on which a user may act.

As already explained, the adjustment lever 70 may be pivotably mounted on the housing 9. For this purpose, a lever bearing projection 71.1 may be provided on the housing 9, in particular on the first housing half 10 (see Figure 21 ). Thus, a lever bearing 71 may be formed by receiving the lever bearing projection 71.1 in the lever bearing receptacle 71.2.

As previously mentioned, the guide element 78.2 of the bearing element 75 may be guided on the guideway 14. This is shown in more detail in Figure 21. Here, for a better overview, only the first housing half 10 and the engaging lever 78 are shown in Figure 21 .

The guideway 14 may be designed as a closed-loop revolving guide and have a tensioning portion 14.1 and a return portion 14.2. The guideway 14 may define a motion trajectory B of the guide element 78.2 when the bearing element 75 is moved relative to the housing 9. Here, a movement in a first adjustment direction S1 , which is directed to the right in Figure 21 , may correspond to an increase in the preload of the spring element 65. An movement of the bearing element 75 in the opposite second adjustment direction S2 may correspond to a decrease of the preload of the spring element 65.

The tensioning portion 14.1 may comprise a first detent section 14.11 , a second detent section 14.14 and a third detent section 14.18. The detent 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. Accordingly, a movement of the bearing element 75 in the second adjustment direction S2 may be prevented if the guide element 78.2 is moved into one of the detent sections 14.11 , 14.14, 14.18.

Along the motion trajectory B, a first detent section 14.12 may be arranged between the first detent section 14.11 and the second detent section 14.14. Furthermore, a second deflection section 14.15 and a third deflection section 14.16 may be provided between the second detent section 14.14 and the third detent section 14.18. The deflection sections 14.12, 14.15, 14.16 may cause a change in direction of movement of the guide element 78.2 . For example, the guide element 78.2 may initially perform a movement in the first adjustment direction S1 when it is moved away from the first detent section 14.11 . In other words, the direction of movement of the guide element 78.2 may initially correspond to the direction of movement of the bearing element 75. At the deflection sections 14.12, 14.15, the guide element 78.2 may undergo a change of direction. The engaging lever 78 may pivot in this case.

As can be further seen in Figure 21 , a first intermediate detent section 14.13 may be provided between the first deflection section 14.12 and the second detent section

14.14. Further, a second intermediate detent section 14.17 may be provided between the third deflection section 14.16 and the third detent section 14.18. The intermediate detent sections 14.13, 14.17 may be designed in such a way that the guide element 78.2 is held on them against the first adjustment direction S1. Accordingly, a movement of the bearing element 75 in the first adjustment direction S1 may be prevented if the guide element 78.2 is moved into one of the intermediate detent sections 14.13. The third detent section 14.18 may be, along the motion trajectory B, followed by the return portion 14.2. For example, the third detent section 14.18 may be followed by a fourth deflection section 14.21. The fourth deflection section 14.21 may be followed by a 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 with the tensioning portion 14.1 , in particular with the first detent section 14.11.

As can be seen in particular in figure 24, the device 1 may comprise the latch 80. The latch 80 may be mounted on the housing 9, preferably on the second housing half 20. For this purpose, a latch receptacle 28 may be provided on the second housing half 20.

The latch 80 is shown in more detail in Figure 25. The latch 80 may be an elastic and/or an elastically deformable and/or displaceable element, which preferably has a base member 83. A spring section 82 may be connected to the base member 83. The spring section 82 preferably has an elastically resilient design. As shown in the figures, the spring section 82 may have a meander-shaped profile section. In this way, elastic resiliency may be achieved with a flat design.

The spring section 82 may be followed by a bearing section 81 . The bearing section 81 may preferably have retaining projections 86.2. The retaining projections 86.2 may be held, in particular latched, in latch bearing receptacles 28.2 (see Figure 23) in the region of the latch receptacle 28 of the second housing half 20. Thus, the latch 80 may be supported on the housing 9 against an acting force in the direction from the base member 83 to the bearing section 81 .

Furthermore, the latch 80 may have one or more displacement projections 86.3. As can be seen from Figure 25, displacement projections 86.3 may preferably be provided on the spring section 82 and on the base member 83. The displacement projections 86.3 may be guided on displacement receivers 28.3 (see Figure 23) in the area of the latch receptacle 28. Preferably, the displacement receivers 28.3 are longer than the displacement projections 86.3, whereby a displaceability of the displacement projections 86.3 may be ensured. Furthermore, a guide projection 86.1 may be provided on the base member 83, which may be guided in a guide receptacle 28.1 (see Figure 23) in the area of the latch receptacle 28.

As can be seen from Figure 25, a deflection surface 87 may be provided on the base member 83. Via the deflection surface 87, a force may be introduced into the latch 80, which may cause an elastic deformation of the latch 80, preferably of the spring section 82, in the direction of the bearing section 81. Preferably, the deflection surface 87 may be provided on a spring projection 84. The spring projection 84 may be formed as an elastically deformable angled section on the base member 83. Accordingly, there is further resiliency of the latch 80 in addition to the resiliency of the spring section 82.

As can be seen in Figure 24, the latch 80 may be arranged at least partially in the region of the guide track 12. Preferably, the guide track 12 may also be provided on the second housing half 20 for this purpose. The guide element 42 of the pivoted lever 40 may thus be guided on the guide track 12 on the first housing half 10 and on the second housing half 20.

Figure 24 shows the latch 80 in an undeformed basic position. Here, the latch 80 may preferably rest with its deflection surface 87 against the guide track 12, in particular as shown in such a way that the swivel-out section 12.3 is closed by the latch 80. However, due to the elastic deformability of the latch 80, the swivel-out section 12.3 may be released when the guide element 42 is moved from the ejection section 12.2 into the swivel-out section 12.3.

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. As can be seen from Figure 24, the detent area 85 may cooperate with the guide track 12 to at least partially form the second detent section 12.4 of the guide track 12. Thus, after the guide element 42 has been displaced by the swivel-out section 12.3, it may be retained at the second detent section 12.4. A return to the swivel-out section 12.3 may be prevented by the latch 80, since in this position the guide element 42 cannot exert a force component on the latch 80 that could displace it toward the bearing section 81 .

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

In Figure 2, a first state is shown in which the movable furniture part may be in a closed state. The driver 2 may be in contact with the driver stop 51. The carriage 30 is in the retracted position. The preload of the spring element 65 acts on the carriage 30 via the transmission attachment 62 of the spring carriage 60.

The further driver stop 45 is pivoted away from the motion trajectory of the driver 2. Likewise, the deflecting surface 49.5 is pivoted away from the motion trajectory of the driver 2.

The pusher 50 is in a rest position. The trigger 90 is in a blocking position. Here, the retainer attachment 98 projects into the guide track 12. The guide element 42 is located in the first detent section 12.1 and is held there on the retainer attachment 98.

In Figure 14, a further condition is shown in which a force is exerted by the driver 2 on the driver stop 51 . This may correspond to an overstroke exerted by a user on the movable furniture part. As a result, the pusher 50 is moved from its rest position against the pretension of the spring 55 into an adjustment position. By force transmission between the pushing surface 54.3 of the pusher 50 and the activation surface 93 of the trigger 90, the trigger 90 is moved into a release position. In Figure 14, the trigger 90 is moved to the left in the image plane against the pretension of the return spring 99. This moves the retainer attachment 98 away from the guide track 12. Accordingly, the first detent section 12.1 is released and the guide element 42 may be moved into the ejection section 12.2.

Thus, the trigger 90 and/or the retainer attachment 98 of the trigger 90 may also be construed as a latch that permits pivoting of the pivoted lever 40 from the pivoted-out position to the pivoted-in position and blocks pivoting of the pivoted lever 40 from the pivoted-in position to the pivoted-out position.

Further, the movement of the trigger 90 causes the first synchronizing element 101 to rotate, and the rotation of the first synchronizing element 101 may be transmitted to a second synchronizing element 105 on a second device 1 ' by means of the synchronizing shaft 100. Thus, a second coupled device T may also be triggered.

Figure 15 shows a situation in which the carriage 30 is in a range of movement between the retracted position and an ejected position. The carriage 30 has been moved while reducing the preload of the spring element 65. The guide element 42 is located in the ejection section 12.2. The further driver stop 45 is further pivoted away from the motion trajectory of the driver 2. As can be seen further from Figure 15, the trigger 90 is again moved back to its blocking position by the pretension of the return spring 99. The pusher 50 is moved back to its rest position by the pretension of the spring 55. Via the driver stop 51 , the movement of the carriage 30 is transmitted to the driver 2, whereby the movable furniture part is ejected.

Figure 16 shows the ejected position of the carriage 30. Advantageously, a plug 19 made of a flexible material may be provided on the housing 9, which may at least reduce a hard stopping of the carriage 30 in the ejected position. After passing through the ejection section 12.2, the guide element 42 has been displaced along the swivel-out section 12.3. The driver 2 is no longer located in the area of the further driver stop 45 and the deflecting surface 49.5. Accordingly, the driver 2 does obstruct a pivoting out of the pivoted lever 40.

According to Figure 16, the guide element 42 is now in the second detent section 12.4. Here, the guide element 42 has elastically deformed the latch 80 during its displacement along the swivel-out section 12.3 to briefly release the swivel-out section 12.3. After the latch 80 is reset, the swivel-out section 12.3 is blocked again and the guide element 42 is prevented from returning to the swivel-out section 12.3. The pivoted lever 40 has been moved to an pivoted-out position by the displacement of the guide element 42 at the swivel-out section 12.3. Thus, the further driver stop 45 is now in the motion trajectory of the driver 2. The movable furniture part may now be further ejected by the momentum of the ejection movement and/or by manual extraction. This causes the driver 2 to move further away from the further driver stop 45 along its motion trajectory.

The ejected position shown in Figure 16 may represent a waiting position of the device 1 . If the movable furniture part is now moved again in the closing direction, the driver 2 meets the further driver stop 45, as shown in Figure 17. The pivoted lever 40 is in the pivoted-out position and the further driver stop 45 is arranged in the motion trajectory of the driver 2.

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

According to Figure 18, the guide element 42 has reached the swivel-in section 12.6 after passing through the swivel-in section 12.5. However, the pivoted lever 40 is still in the pivoted-out position. Accordingly, the further driver stop 45 is still in the motion trajectory of the driver 2. When further force is applied by the driver 2 to the further driver stop 45, the guide element 42 is displaced along the swivel-in section 12.6 and reaches the first detent section 12.1. Here, the deflection roller 45.1 may advantageously roll on the driver 2. Due to the design of the pivoted lever 40, the application of force by the driver 2 is advantageously translated into a torque that assists the swing-in movement.

When the guide element 42 has reached the first detent section 12.1 , the pivoted lever 40 is in the pivoted-in position. Accordingly, the further driver stop 45 has swung away from the motion trajectory of the driver 2. Now the driver 2 may be moved towards the driver stop 51 , whereby the driver 2 is released from the force of the spring element 65. In other words, this results in a free run of the driver 2 towards the end of the drawing-in movement. It is conceivable that a drawing-in device is provided, which acts on the movable furniture part at least during the free run and at least supports the completion of the drawing-in movement. Alternatively, the driver 2 may also only be moved manually into the final closed position during the free run.

When the driver 2 is moved back into the vicinity of the driver stop 51 , the initial position shown in Figure 2 is reached again.

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

In Figure 2, a setting corresponding to a minimum pre-adjusted preload of the spring element 65 is shown. Accordingly, the guide element 78.2 of the engaging lever 78 is located in the area of the first detent section 14.11 of the guideway 14.

To increase the preload, a user may now act on the operating surface 70.3 of the adjustment lever 70 substantially in the first adjustment direction S1 . This causes the adjustment lever 70 to pivot. By means of the transmission element 76 of the bearing element 75 and the counter transmission element 72 of the adjustment lever 70, the pivoting of the adjustment lever 70 is translated into an adjustment of the bearing element 75. Accordingly, the bearing element 75 may be moved in the first adjustment direction S1 .

Consequently, the guide element 78.2 is also initially moved along the first adjustment direction S1 , until it reaches the first deflection section 14.12. There it is deflected towards the first intermediate detent section 14.13. When the guide element 78.2 reaches the area of the first intermediate detent section 14.13, it is held there against the first adjustment direction S1 . Thus, the user is facing a resistance opposed to a further adjustment of the adjustment lever 70 in the first adjustment direction S1 . When the user now ends application of force to the operating surface 70.3, the guide element 78.2 may be moved into the second detent section 14.14 under the action of the force of the spring element 65. Thus, the preload of the spring element 65 may be increased by one step compared to the situation shown in Figure 2. Consequently, the user receives haptic feedback that a higher level of preload has been reached.

In a comparable manner, a further level of increased preload may be achieved by the user again acting on the operating surface 70.3 of the adjustment lever 70. Accordingly, the guide element 78.2 may now be moved from the second detent section 14.14 via the second deflection section 14.15 and the third deflection section 14.16 into the second intermediate detent section 14.17. From the second intermediate detent section 14.17, the guide element 78.2 again moves to the third detent section 14.18 when the user stops applying force to the operating surface 70.3. The third stage of adjustable pretension of the spring element 65 has thus been reached.

From the third detent section 14.18, the guide element 78.2 may be displaced into the range of the fourth deflection section 14.21 when a further force is applied to the operating surface 70.3. The guide element 78.2 thus enters the return portion 14.2. Along the return portion 14.2, the guide element 78.2 may initially be moved 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 may now be returned to the first detent section 14.11 . Thus, the first stage of the adjustable pretension as shown in Figure 2 is achieved again.

In the following, a possible assembly procedure of a device 1 will be explained in more detail.

For example, the return spring 99 may first be connected to the spring bearing 16.4. Here, a first leg 99.1 is inserted into a spring retainer 16.5. A second leg 99.2 may initially remain free. At the trigger 90, the damper may be inserted into the damper receptacle 91.1. Now the trigger 90 may be inserted into the trigger receptacle 16. Here, the second leg 99.2 of the return spring 99 may first be inserted into the support area 92.1 of the trigger 90. When the trigger 90 is inserted into the trigger receptacle 16, the return spring 99 is also securely held. Further, the spring carriage 60 may be inserted into the spring carriage guide 13. Here, the latching hooks 13.1 , 13.2 may be engaged with the guide webs 64.1 . In the following, the spring element 65 may already be inserted on one side into the spring bearing 63 of the spring carriage 60.

It is conceivable to next preassemble the bearing element 75. Here, the engaging lever bearing extension 78.1 of the engaging lever 78 may be connected to the engaging lever bearing 77.1 of the bearing element 75. The preassembled bearing element 75 may then be inserted into the bearing element guide 15. Preferably, the guide element 78.2 is inserted here into the first detent section 14.11 of the guideway 14.

Now the adjustment lever 70 with its lever bearing receptacle 71 .2 may be placed on the lever bearing projection 71.1 of the housing 9. Here, the counter transmission element 72 of the adjustment lever 70 may be placed on the transmission element 76 of the bearing element 75.

The spring element 65 may now be inserted into the spring mount 73 of the bearing element 75.

In a next step, it is conceivable to preassemble the carriage 30 with the pusher 50 and the pivoted lever 40. The deflection roller 45.1 may first be mounted on the pivoted lever 40. Also, the damper 47.2 may be inserted into the damper receptacle 47.1. The pivoted lever 40 may then be mounted with the pivoted lever bearing area 41 on the pivoted lever bearing attachment 37.1 of the carriage 30.

The pusher 50 may first be provided with the spring 55. For this purpose, the spring 55 may first be fitted with its second spring end 55.2 onto the pin 54.1 . Subsequently, the first spring end 55.1 may be supported on the spring bearing 53. Finally, the pusher 50 may be inserted into the pusher receptacle 36 of the carriage 30. Advantageously, the pusher 50 may be latched with its latching elements 56 to the counter latching elements 36.2 of the pusher receptacle 36. Now the carriage 30 may be inserted with its projections 32.1 , 32.2, 32.3 into the guide receptacles 11.1 , 11.2, 11.3, 11.4. Here, the clamp attachment 38 of the carriage 30 may also be engaged with the transmission attachment 62 of the spring carriage 60. If necessary, the spring carriage 60 might need to be displaced slightly along against the pretension of the spring element 65.

The pivoted lever 40 may be in its pivoted-out position when the carriage 30 is inserted. Thus, the guide element 42 may be inserted into the retraction section 12.5 or the second detent section 12.4. Finally, the plug 19 may be inserted.

It is now conceivable to insert the latch 80 into the latch receptacle 28 in a further step. To do this, the retaining projections 86.2 may first be engaged with the latch bearing receptacles 28.2. Subsequently, the displacement projections 86.3 may be engaged with the displacement receivers 28.3.

If a device 1 having a first synchronizing element 101 and a trigger 90 and a second device T having a second synchronizing element 105 and preferably a second trigger 90' are provided, the further assembly steps may differ between the first and the second device 1 .

The first device 1 may now be completed by bringing the first housing half 10 into connection with 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.

The first synchronizing element 101 may be inserted into the shaft opening 17 of the first device 1 in a later step. For this purpose, the first synchronizing element 101 is inserted such that the transmission element 102 is in an orientation such that it may be engaged with the second transmission counter element 96.

Preferably, the second synchronizing element 105 may be inserted into the second device T before the first housing half 10 and the second housing half 20 are connected. The retaining section 108 is held at the retaining shoulder 17.2 of the shaft opening 17 of the second device T. The transmission element 106 of the second synchronizing element 105 is engaged with the first transmission counter element 95 of the second trigger 90'. It is now conceivable to complete the assembly of the second device T by connecting the first housing half 10 to the second housing half 20.

The first device 1 and the second device T may now be mounted opposite each other on a movable furniture part or a furniture body. If synchronization between the devices 1 , T is intended, the first synchronizing element 101 may now first be inserted with its profile section 104 into the counter profile section 112.2 of the connecting part 110. The adapter 113 may be inserted with its profile section 114 into the opposite counter profile section 111.2 of the connecting part 110. Subsequently, the first synchronizing element 101 may be inserted into the shaft opening 17 of the first device 1 in the manner described above.

Now, the adapter 113 with its coupling section 115 may be engaged with the coupling section 109 of the second synchronizing element 105 of the second device T. Advantageously, the coupling receptacle 115.1 is thereby placed on the coupling section 109 in a direction that is substantially perpendicular to the longitudinal axis of the second synchronizing element 105. Hence, the coupling portion 115 of the adapter 113 may pass through the cutout 17.3 of the shaft opening 17.

As shown above, a device 1 for ejecting a movable furniture part is provided. The device 1 comprises a housing 9 and a carriage 30 movable relative to the housing 9. The carriage 30 is movable between a retracted position and an ejected position. The carriage 30 comprises a pivoted lever 40 which is pivotable between a pivoted-in position and a pivoted-out position. A latch 80 is provided. The latch 80 permits pivoting of the pivoted lever 40 from the pivoted-in position into the pivoted-out position and blocks pivoting of the pivoted lever 40 from the pivoted-out position into the pivoted-in position. Alternatively, the latch 80 permits pivoting of the pivoted lever 40 from the pivoted-out position into the pivoted-in position and blocks pivoting of the pivoted lever 40 from the pivoted-in position into the pivoted-out position.
