Description

State of the art

Devices for influencing the movement of the furniture part are used for furniture parts such as drawers, furniture doors or furniture flaps, which are movably accommodated on a furniture body of a piece of furniture via guide means. Such devices are formed, for example, by a unit which can be attached to the furniture part, the furniture body or the guide means at a suitable point.

In particular, the guiding means comprise a sliding guide, such as a full or partial extension, or a pivoting guide, such as a furniture hinge.

In the case of modern and user-friendly furniture, devices for moving the furniture part are known, for example, which can optionally be provided to provide an additional function, in particular to make it easier for a user to open the furniture part. The additional function can be matched in particular to the type and size of the furniture part. The device for influencing the movement of the furniture part relates, for example, to systems for providing a power-assisted opening function for the furniture part. The disadvantage of such a known device is that, especially in the case of a comparatively heavy drawer, the device is loaded by the closing movement of the drawer, particularly when the drawer has comparatively high kinetic energy, and is then activated—undesirably by the user—so that the drawer is ejected again. However, this is precisely against the user's desire to operate it.

Object and advantages of the invention

The object of the present invention is to further develop a device for moving a movable furniture part, in particular to improve the device for moving the movable furniture part in such a way that an unintentional triggering of an opening process of the device during a charging process of the device and/or in particular directly afterwards charging of the device is prevented.

This object is solved by the independent claims.

Advantageous variants of the invention are shown in the dependent claims.

The invention is based on a device for moving a movable furniture part in an opening direction in relation to a furniture body of a piece of furniture, with the movable furniture part being able to be brought into the opening direction and in a closing direction opposite to the opening direction via guide means, the device having an energy store and an ejector has, so that with the device mounted on the piece of furniture, the movable furniture part can be moved during an opening process from the closed position under the action of the energy store in the opening direction, in that the energy store drives the ejector from a closed position of the ejector in an opening movement of the ejector in an opening direction and the opening movement of the ejector can be transferred to the movable furniture part, with a closing movement of the ejector from an open position of the ejector in a closing direction allowing the energy store to be loaded, the device device has a locking arrangement with a triggering element, wherein the locking arrangement is designed to keep the energy accumulator in the charged state in a locking position of the locking arrangement, the ejector being movable in a closing movement in the closing direction from the closed position into a triggering position of the ejector, wherein the closing movement of the ejector can be transferred to the triggering element, so that the triggering element can be brought from a rest position into a triggering position, with the force accumulator being unlocked in the triggering position of the triggering element.

A movable furniture part is designed, for example, as a drawer, a furniture flap and/or a furniture door. The guide means are designed, for example, as an extension, e.g. as a full extension. The guide means include, for example, a drawer rail and a cabinet rail. It is also conceivable that the guide means additionally have a center rail. It is also conceivable that the guide means comprise a hinge or a lever mechanism, e.g. the guide means form a flap fitting.

The device for triggering the opening movement of the ejector preferably has a so-called touch-latch function or a touch-latch arrangement. When the touch-latch function is integrated in the device, the movable furniture part, which is closed on the furniture body and is generally held in the closed position, is moved by a movement of the movable furniture part in the closing direction over a comparatively short movement path of the movable furniture part, which describes the triggering process. The triggering process is, for example, a prerequisite for the opening movement of the movable furniture part, which is force-assisted by the energy accumulator, to take place. Moving the moveable furniture part to trigger is advantageously done by the user from the outside, who presses against a front of the movable furniture part, for example.

In the closed position of the movable furniture part, a front element of the movable furniture part, e.g. a drawer front, is advantageously present at a distance from a front side of the furniture body. For example, in the closed position, a gap is formed between the front element of the movable furniture part and the front side of the furniture body, which forms a natural stop for the movable furniture part.

The moveable furniture part is moved out in the opening direction relative to the furniture body under the energy storage effect of the device arranged on the furniture over at least part of a maximum opening path provided by the guide means for the moveable furniture part on the body.

The essential aspect of the invention can now be seen in the fact that a closing movement of the ejector is transmitted to the triggering element by means of a triggering member of the device, the device having a guideway, the ejector being guided in the guideway, the guideway being designed in this way that when the ejector moves from an open position of the ejector in the closing direction, the triggering element can be brought into a securing position, with the ejector being in the securing position of the triggering element in the triggering position and the triggering element being in the rest position, so that the triggering element is triggered by the ejector is prevented when the triggering element is in the secured position.

This prevents an opening process from being triggered, in particular unintentionally, under the action of the energy accumulator after the loading process has been completed by a further, in particular continuously continued, closing movement of the movable furniture part. For example, this prevents the energy store from being triggered and the moveable furniture part being ejected again by the energy store as a result of comparatively strong or rapid movement of the movable furniture part in the closing direction, e.g. due to further movement of the movable furniture part due to inertia of the movable furniture part.

The device according to the invention is preferably designed such that when the device is arranged on the piece of furniture, a closing movement of the movable furniture part relative to the furniture body recharges the energy store that was at least partially discharged during the opening process or can be brought back into the clamped state. The force required for this is e.g. applied by the user when the user moves the movable furniture part in the closing direction, e.g. presses it.

Preferably, the closing direction of the ejector in the arranged state of the device on the piece of furniture is parallel and parallel to the closing direction of the movable furniture part. It is also conceivable that the closing direction of the ejector is parallel to and in the same direction as the opening direction of the movable furniture part when the device is in the arranged state on the piece of furniture. Advantageously, the device can be arranged both on the furniture body and on the movable furniture part. Advantageously, the opening direction and the closing direction of the ejector are oppositely aligned. For example, the opening direction and the closing direction of the ejector are aligned parallel to one another.

It has proven to be advantageous that the triggering element is movably arranged on the ejector. Advantageously, the triggering member is present on the ejector so that it can pivot. In particular, the triggering element is rotatably arranged on the ejector. It is also conceivable that the triggering element is arranged on the ejector in a linearly movable or displaceable manner in relation to the ejector.

Preferably, the triggering member is movable relative to the ejector in a direction transverse to an opening and/or closing direction of the ejector. For example, a pivot axis of the triggering element is aligned transversely, in particular perpendicularly, to an opening and/or closing direction of the ejector. Advantageously, the triggering member can assume the safety position and an operative position on the ejector. For example, the triggering element is arranged on the ejector so that it can be moved from the safety position into the active position and vice versa.

It is also proposed that the device has a spring element, the spring element being present in such a way that the spring element forces and/or moves the ejector from the release position into the closed position when the release member is in the secured position. This enables the device to be triggered after it has been closed. For example, in the release position, the ejector is acted upon by the spring element with a spring force, in particular with a spring force in the opening direction of the ejector. Advantageously, when the triggering member is in the secured position, the ejector is subjected to a spring force by the spring element in the triggering position.

Advantageously, the spring element acts directly on the triggering element in the securing position of the triggering element and/or in the triggering position of the ejector, in particular with its spring force. For example, in a closing movement of the ejector, the spring element acts directly on the triggering element, in particular with its spring force. The locking arrangement advantageously includes the spring element. The spring element is designed, for example, as a leaf spring, a torsion spring or as a spiral spring.

Advantageously, the spring element is designed and/or arranged on the device in such a way that, when the triggering element is in the securing position, the spring element acts on the triggering element with a spring force, so that the spring force means that the triggering element can be moved out of the securing position with the ejector in the opening direction of the ejector. As a result, the ejector can be brought into the closed position and the triggering element into the active position. The spring element is preferably designed in such a way and/or arranged on the device in such a way that the spring element acts with a spring force on the triggering element during a closing movement of the ejector. Advantageously, the spring element is designed and/or arranged on the device such that movement of the triggering member relative to the ejector is prevented during a triggering movement of the ejector from the closed position of the ejector in the closing direction into the triggering position of the ejector. The spring element is preferably designed and/or arranged on the device in such a way that during a triggering movement of the ejector from the closed position of the ejector into the triggering position of the ejector, movement of the triggering element from the active position into its securing position is prevented.

It is also advantageous that the ejector includes the spring element. As a result, a comparatively compact design of the ejector can be realized. For example, the spring element is arranged on the ejector. It is also conceivable that the spring element is attached to the triggering element. The spring element advantageously acts in particular directly between the ejector and the triggering element. It is conceivable that the elastic element is present as the spring element. It is also conceivable that the device has both the spring element and the elastic element. It is conceivable that the elastic element is present in the form of a film hinge. For example, the elastic element is a film hinge. It is also conceivable that a force of the elastic element on the triggering element and a force of the spring element on the triggering element are opposite to one another and/or are aligned opposite to one another.

In an advantageous embodiment of the invention, the spring element is arranged on a base body of the device. The guide track is advantageously formed on the base body. For example, the base body includes the guideway. The spring element preferably acts in particular directly between the base body and the triggering element. It is also conceivable that the spring element is arranged on the triggering element. For example, the spring element is linearly movable relative to the base body. For example, the spring element is movable relative to the base body together with the triggering element. The triggering element is advantageously arranged on the base body in a linearly movable manner. In particular, the triggering element is linearly movable in an opening and closing direction of the ejector.

It is also advantageous that the base body has a guide link, the triggering element being guided at least in sections by the guide link. For example, the triggering element comprises a guide element which interacts with the guide link and/or by means of which the triggering element is guided through the guide link. For example, the triggering element is in direct contact with the guide link, at least in sections. It is also conceivable that the ejector is present between the guide link and the triggering element and the triggering element is guided by the ejector due to an interaction of the ejector with the guide link. For example, the guide link is part of the guideway or vice versa.

It is also proposed that the guide link of the base body is designed in such a way that the guide link blocks a movement of the ejector from the closed position of the ejector into an open position. Advantageously, the guide link blocks a movement of the triggering element in the opening direction of the ejector and thus also a movement of the ejector from the closed position into an open position. The guide link preferably has a blocking element, for example in the form of a stop for the triggering element. For example, the blocking element forms a stop for the guide element of the triggering member. For example, the spring element and/or the elastic element forces the triggering element against the blocking element when the ejector is in the closed position. The triggering member is advantageously in its active position when the ejector is in the closed position. Blocking of the movement of the ejector is preferably off the closed position into an open position can be canceled in that the triggering element is moved against a force, in particular a spring force, for example of the spring element and/or for example of the elastic element. In particular, a blocking of the movement of the ejector from the closed position into an open position can be canceled by moving, in particular pivoting, the triggering member in a direction transverse to an opening and/or closing movement of the ejector. A force of the energy store is advantageously greater than a force of the spring element and/or than a force of the elastic element. In this way, for example, the blocking of the triggering element can be released in a triggering process of the device.

It also proves to be advantageous that the triggering element is designed as an elastic element. For example, the triggering element is designed to be elastic. Advantageously, the triggering element is resiliently mounted on the ejector. It is also conceivable that the triggering member is present integrally with the ejector. For example, the triggering element is coupled, in particular connected, to the ejector via an elastic element. For example, the ejector, the elastic element and the triggering member are present in one piece or integrally. As a result, manufacture of the device parts is comparatively simplified and/or cheaper.

In an advantageous embodiment of the device, the device has a slotted guide, the triggering element being guided at least in sections by the slotted guide when it moves out of the securing position in the opening direction of the ejector. The link guide is designed, for example, in the form of a ramp. Advantageously, the link guide is formed on the base body of the device. The triggering element of the locking arrangement preferably includes the link guide, the triggering element being guided at least in sections by the link guide of the triggering element when it moves out of the securing position in the opening direction of the ejector. Advantageously, the device is designed in such a way that the triggering member is present, guided by the link guide when the ejector moves in the opening direction of the ejector, from its secured position to its active position.

A closed position, a release position, an active position and/or a safety position are preferably considered to be one area. For example, the ejector and/or the triggering element can assume several different positions within the respective area. For example, within the respective area, the ejector and/or the triggering element can assume several different positions along a closing and/or opening direction of the ejector.

It is also advantageous that the device has a damping element. For example, the damping element includes a spring element, e.g., a spring. A movement of the ejector from the closed position into the release position is advantageously damped and/or braked by the damping element. The ejector preferably acts directly on the damping element. It is also advantageous that the ejector is always in contact with the damping element in the release position. The damping element is advantageously present in such a way that it moves the ejector from the release position into the closed position. It is also advantageous that the device is designed in such a way that the ejector contacts the damping element in a closing movement in the direction of the release position, in particular in a release process, before the release element interacts with the release element, in particular before the release element contacts the release element. For example, the device is designed such that the ejector first contacts the damping element in a closing movement, in particular out of the closed position, in the direction of the release position and then the release member interacts with the release element. For example, the device is designed in such a way that, in order to trigger the triggering element, the ejector first contacts the damping element in a closing movement in the direction of the triggering position and then the triggering member interacts with the triggering element.

An advantageous embodiment of the invention is a piece of furniture with a device according to one of the embodiments described above. For example, the piece of furniture comprises a furniture body and a movable furniture part arranged movably thereon. Advantageously, the device can be arranged on the furniture body and/or on the movable furniture part.

A piece of furniture 50 with a box-shaped furniture body 51 and a drawer 53 that is movably guided via guide means 52 is in 1 shown. The drawer 53 comprises a drawer base 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57. To guide the drawer 53, there are two guide means 52 with the same effect, each between each side wall 56 of the drawer 53 and an associated body side wall 58. A device 1, 2 according to the invention (shown in phantom) for moving or ejecting the furniture part designed as a drawer 53 in the opening direction M1 is arranged on the underside of the drawer base 54.

The device 1 is used for power-assisted ejection of the drawer 53 over a first partial distance of an opening movement of the drawer 53 from a closed position relative to the furniture carcass 51 in the opening direction M1 of the drawer 53. The drawer 53 is via the guide means 52, for example two identical partial or Full extensions, mounted on the furniture body 51 so that they can be moved in the direction of M1 and M2. The device 1 can alternatively be arranged on the furniture body 51 or on the guide means 52 of the piece of furniture 50 .

The device 1 comprises, among other things, a base body in the form of a base plate 3, an energy store 4, a coupling device 5, an ejector 6 and a locking arrangement 7. A triggering element 8 can be movably arranged on the ejector 6. For example, the triggering element 8 is designed in the form of a pressure piece. For example, the locking arrangement 7 includes a triggering element 9. For example, the triggering element 9 is designed as a trigger. It is also conceivable that a damping element 11 is present. For example, the damping element 11 includes a spring 12. Advantageously, the device 1 includes a spring element 26, in particular in the form of a leaf spring.

A guide track 10 is advantageously formed on the base plate 3 . Preferably, the base plate 3 includes a guide link 25. For example, the spring element 26 is arranged with a first end 27 on the base body 3, in particular fixed in position.

Furthermore, an assembled state of the device 1 on the drawer bottom 54 is assumed.

A housing of the device 1 comprises the base plate 3 and a cover component, which is not shown. The device 1 can be arranged on the underside of the drawer bottom 54 and/or on the guide means 52 via the housing or via the cover component and/or the base plate 3 .

Holding sections, guide contours, stop elements and/or receiving sections for connecting the individual components of the device 1 are formed on the base plate 3 .

Advantageously, the energy store 4 according to the exemplary embodiment shown comprises two parallel spiral springs 13, 14 of the same type, which form a spring assembly. For example, the spiral springs 13, 14 are arranged on an adjustable fixed bearing 15 at a first end of the force accumulator 4. The fixed bearing 15 advantageously comprises a movable bearing part 16, on which the spiral springs 13, 14 are detachably but firmly accommodated, and an adjusting part 17 with an operating section 18, via which a user can adjust the position of the end of the energy accumulator 4 from the outside in a variable position-fixed manner. As a result, a force effect of the energy store 4 on the drawer 53 when the drawer 53 is opened can advantageously be preset.

The associated ends of the spiral springs 13, 14 are preferably attached to a carriage-like moving element 19 at a second end of the force accumulator 4. The carriage-like movement element 19 is linearly guided in a movement direction P1 and an opposite movement direction P2 via an associated guide contour on the base plate 3 .

The directions of movement P1 and P2 of the movement element 19 run parallel to the opening direction M1 of the drawer 53 and a closing direction M2 opposite thereto.

If the device 1 is arranged in a fixed position on the furniture body 51 and/or on a stationary part of the guide means 52, the opening direction of the drawer 53 corresponds to the direction P1 and the closing direction of the drawer 53 to the direction P2.

For example, the ejector 6 can be moved exclusively linearly or back and forth parallel to the movement direction of the movement element 19 in the directions P1 and P2. For this purpose, the guide track 10 is formed on the base plate 3, which is matched to guide sections, e.g. on one side of the ejector 6.

An opening process of the drawer 53 brought about by the device 1 advantageously takes place exclusively via a direct operative connection of the energy store 4 via the movement element 19 moving in direction P2 to the ejector 6 . For this purpose, a stop element 20 is formed on the movement element 19, which is advantageously designed to be elastic and thus prevents or at least dampens a noise that is annoying to the user if the movement element 19 strikes the ejector 6 when the drawer 53 is opened.

In addition to a clamping lever 21, the coupling device 5 preferably comprises an adjusting lever 22 and a connecting lever 23. The clamping lever 21 is articulated at a second end via a bearing pin on the adjusting lever 22. The connecting lever 23 is also articulated at a second end via a further bearing pin spaced apart from the bearing pin on the actuating lever 22 and at its first end via a further bearing pin on the movement element 19 . The adjusting lever 22 can be moved at a first end via a further bearing pin, in particular pivotably arranged on the base plate 3, the bearing pin preferably being accommodated both on the base plate 3 and on the cover component (not shown). The adjusting lever 22 is advantageously mounted such that it can pivot and/or rotate about an axis of rotation for loading the energy accumulator 4 .

Due to its configuration, the adjusting lever 22 can transmit a force with a translation from the clamping lever 21 to the connecting lever 23 when the energy accumulator 4 is being clamped. The transmission ratio is formed on the one hand by the ratio of the distance between the bearing journals on the adjusting lever 22 and on the other hand by the combined circular and linear movement of the clamping lever 21 and/or the connecting lever 23 to one another during the charging process of the energy store 4.

Due to the configuration mentioned above, the coupling device 5 can transmit a force for tensioning the energy store 4 from the ejector 6 via the tensioning lever 21 and the adjusting lever 22 to the connecting lever 23 and thus to the energy store 4 in a geared manner; in particular, the coupling device 5 reduces the force exerted by the ejector 6 on the energy store 4. This means that when loading the energy store 4, a user has to apply less force to the ejector 6 than he would have to apply if he wanted to load the energy store 4 without a gear reduction.

The tensioning of the energy accumulator 4 is advantageously completely completed before, for example, an automatic retraction mechanism of the device 1 (not shown) for force-assisted retraction of the drawer 53 into the completely closed closed position on the furniture body 51 becomes effective. The automatic retraction is e.g. not part of device 1.

In a closing movement of the drawer 53, the ejector 6, starting from an open position, is moved in the closing direction P2 by a driver 24, which in the exemplary embodiment described is in particular fixed in position on the furniture body 51.

In the 2 until 5 and 7 until 9 the device 1 is shown in different positions of its elements. In the 2 , 3 and 7 the energy accumulator 4 is shown in a loaded position. The energy accumulator 4 is kept in the loaded state by the movement element 19 locking in place with the locking arrangement 7 . In this position, the ejector 6 is decoupled from the locking arrangement 7, for example. In the 2 , 3 and 7 the ejector 6 is shown in a closed position.

Advantageously, the trigger member 8 is rotatably mounted on the ejector 6. For example, the ejector 6 includes a limiting contour 29 which limits a rotational movement of the triggering element 8 relative to the ejector 6 . In the 2 , 3 , and 7 is the trigger 8 shown in an operative position. In the active position, the triggering element 8 is advantageously positioned relative to the ejector 6 in such a way that the triggering element 8 can interact with the triggering element 9 .

The triggering element 8 preferably comprises a guide element 30 which engages in the guide slot 25 when the triggering element 8 is in the arranged state on the base plate 3 . For example, the guide element 30 is designed in the form of a guide pin. It is conceivable that the guide element 30 is present protruding from a base body 32 of the triggering member 8 . The guide link 25 is advantageously designed in such a way that when the ejector moves from the closed position into a release position in the closing direction or vice versa, a movement of the release element 8 relative to the ejector 6 can be implemented.

The triggering element 8 advantageously comprises an elongate base body 32. For example, the triggering element 8 is movably mounted on a first end 33 of the base body 32, in particular rotatably mounted on the ejector 6. Advantageously, the triggering member 8 comprises, at the first end 33, a limiting element 34, for example in the form of a pin. For example, when the triggering element 8 is in the arranged state on the ejector 6 , the limiting element 34 engages in the limiting contour 29 so that a rotational movement of the triggering element 8 relative to the ejector 6 is restricted by the interaction of the limiting contour 29 with the limiting element 34 .

Preferably, the triggering member 8 is plate-shaped with two opposite large side surfaces and two opposite narrow side surfaces. The first end 33 of the trigger member 8 is present at one end of the side surfaces. The triggering member 8 has a second end 35 opposite the first end 33 . Advantageously, in the area of the second end 35 there is a narrow side surface 36 of the triggering element 8 which is beveled. As a result, the second end 35 is present in a comparatively narrow manner. For example, the triggering member 8 is provided with a recess 37 on the narrow side face opposite the narrow side face 36 . Advantageously, the triggering element 8 comprises a stop 38 at the second end 35, by means of which the triggering element 8 can interact with the triggering element 9 in the active position.

In the 4 and 8th the ejector 6 is shown in the release position. Advantageously, the ejector 6 is in the release position with one end 31 in contact with the damping element 11. The release member 8 is in the 4 and 8th shown in a secure position. For example, in the safety position, the triggering element 8 is present in a position rotated away relative to the ejector 6, contrary to the active position.

In the 5 and 9 the ejector 6 is shown in the release position. The trigger member 8 is in the 5 and 9 shown in the active position. For example, suggests the triggering member 8 according to the position in the 5 and 9 the triggering element 9 with its stop 38 on a triggering surface 39 .

A link guide 28 is preferably present on the triggering element 9 . The link guide 28 is designed, for example, as a bevel, e.g. in the form of a ramp on the triggering element 9. For example, link guide 28 ends at one end of triggering element 9 in triggering surface 39.

In 10 it is shown that the guide link 25 can include a blocking element 40 . The blocking element 40 is designed, for example, as a constriction which forms a transition between the guide track 10 and the guide link 25 . For example, the triggering element 8 with its guide element 30 is guided in the guideway 10 or in the guide slot 25 depending on the position of the ejector 6 relative to the base plate 3 .

A sequence of movements of the ejector 6 and the triggering element 8 starting from an open position of the ejector 6 in the closing direction is described below.

Starting from an open position of the ejector 6 (not shown), the ejector 6 is moved in direction P2 during a closing movement, eg by a closing movement of the drawer 53 by a user in the arranged state of the device 1 on the piece of furniture 50 . In the closing movement, the ejector 6 reaches the closed position according to FIG 2 , 3 and 7 . Due to a closing force that is too great, for example, the ejector 6 can be moved beyond the closed position in the direction P2 during the closing movement.

If the ejector 6 in the closing movement in direction P2 on the closed position according to 2 , 3 and 7 moves out, the triggering element 8 interacts with its guide element 30 with the link guide 25 and is deflected, for example, due to the blocking element 40 and the associated deflection of the triggering element 8 into the right-hand path 41 of the link guide 25. As a result, the release element 8 is activated by the slide guides by moving the ejector 6 further in the direction of the release position tion 25 deflected relative to the ejector 6 from its active position into its secured position. The deflection of the triggering element 8 deflects the stop 38 in such a way that the stop 38 does not come into contact with the triggering surface 39 of the triggering element 9 during the closing movement of the ejector 6 . This prevents the locking arrangement 7 from being triggered, in particular unintentionally.

In the further movement, the spring element 26 comes into contact with the side surface 36, so that the spring element 26 counteracts a deflection of the triggering element 8 through the right-hand path 41 of the link guide 25 with its spring force. As a result, the trigger element 9 in the trigger position of the ejector 6 according to 4 , 7 brought into contact with the connecting link guide 28 of the triggering element 9 with a surface opposite the side surface 36 . Due to the comparatively pointed beveling of the connecting link guide 28, the ejector 6 is moved back into the closed position according to FIG 2 , 3 and 7 emotional. Here, the triggering element 8 slides along the link guide 28 in direction P1 and pivots from the secured position back into the active position, so that the triggering element 8 threads with the guide element 30 into the left-hand path 42 of the link guide 28 .

Due to the bulging of the blocking element 40 to form the constriction, the blocking element 40 forms a natural stop for the guide element 30 during a return movement in direction P1 when it is guided in the left-hand path 42 . In the area of the blocking element 40, the triggering element 8 does not interact with the spring element 26, so that no force acts on the ejector and it remains in the closed position due to the triggering element 8 striking the blocking element 40.

The energy store 4 is triggered by a closing movement of the ejector 6 from the closed position to the release position, e.g. by a closing movement of the drawer 53 by a user in the arranged state of the device 1 on the piece of furniture 50. The ejector, starting from the closed position according to 2 , 3 and 7 in the closing direction P2 in the release position according to 5 and 9 emotional.

In the closed position of the ejector 6 after a return movement from the release position, the guide element 30 of the release element is in the left-hand path 42, which is why the release element 8 is guided in the left-hand path 42 when the ejector 6 moves according to the previous paragraph and in the Active position remains during a closing movement. As a result, the triggering element 8 in the triggering position comes into contact with its stop 38 with the triggering surface 39 of the triggering element 9, so that the triggering element 9 moves out of its rest position (according to 2 , 3 , 7 ) is moved in direction P2 into a release position (not shown in the figures), thereby causing the movement element 19 to be unlocked with the locking arrangement 7 . The unlocking also unlocks the energy store 4 so that the device 1 can eject the drawer 53 due to the force of the energy store 4 (not shown in the figures).
