Such devices serve in particular to bring the movable furniture part via guide means in an opening direction and in a closing direction opposite to the opening direction, the devices having an energy storage device. Under the action of the energy storage, it is possible to eject the movable furniture part in the opening direction via an ejector, that is, to bring it into an open position. Such a device is, for example, in WO 2018/185311 A1 disclosed.

Task and advantages of the invention

The invention is based on the object of providing a device for moving a movable furniture part, in which an opening movement of the movable furniture part is improved.

This task is solved by the features of the independent claim.

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

The invention is based on a device for moving a movable furniture part in an opening direction relative to the furniture body of a piece of furniture, the movable furniture part being able to be brought into the opening direction and into a closing direction opposite to the opening direction via guide means, the device having an energy accumulator and an ejector has, so that with the device mounted on the furniture, the movable furniture part can be moved in the opening direction from a firing position into a first opening position in the opening direction during an opening process under the action of the charged energy storage device via the ejector, in that the energy storage device moves the ejector from a closed position of the ejector in a Opening movement of the ejector drives in an opening direction and the opening movement of the ejector can be transferred to the movable furniture part.

The movable furniture part is preferably connected to the furniture body via guide means, the guide means moving the movable furniture part in the opening and closing directions. The movable furniture part is designed, for example, as a drawer, a furniture flap and/or a furniture door. The guide means include in particular a rail guide, such as a full or partial extension, or a swivel guide, such as a furniture hinge. The guide means include, for example, a drawer rail and a body rail. It is also conceivable that the guide means have a middle rail in addition to the body rail and drawer rail. The middle rail is preferably arranged between the body rail and the drawer rail.

The device according to the invention is preferably designed in such a way that when the device is arranged on the furniture, with a closing movement of the movable furniture part relative to the furniture body, the energy storage device, which was at least partially discharged during the opening process, is recharged or can be brought back into the clamping state. The necessary force is applied by the user, for example, when the user moves the movable furniture part in the closing direction, e.g. presses it.

The device for triggering the opening movement of the ejector preferably has a so-called touch latch function or a touch latch arrangement. If the touch latch function is integrated into the device, this is done on Furniture body closed and generally held in the closed position movable furniture part is moved by an externally caused 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. During the triggering process, the energy accumulator is discharged, whereby the ejector is moved to the first opening position. Moving the movable furniture part or the ejector in the closing direction is advantageously done by the user from the outside, who, for example, presses against a front of the movable furniture part.

Preferably, the closing direction of the ejector when the device is arranged on the furniture is parallel and aligned in the same direction as the closing direction of the movable furniture part. Advantageously, the opening direction and the closing direction of the ejector are aligned opposite to one another. For example, the opening direction and the closing direction of the ejector are aligned parallel to one another.

The movable furniture part is moved out in the opening direction relative to the furniture body under the force storage effect of the device arranged on the furniture over at least a partial distance up to a first opening position, a maximum opening path of the movable furniture part on the furniture body provided according to the guide means.

It is also advantageous if the movement of the ejector in the opening and closing directions can be transferred to the movable furniture part. The ejector is preferably plate-shaped. The ejector preferably has a stop element which can interact with the movable furniture part. The stop element of the ejector is preferably present laterally protruding on the device, so that the movable furniture part rests solely on the protruding stop element of the device during a closing movement in the closing direction Ejector hits and not the rest of the device.

The essence of the invention is that the device has a pawl component and a force unit acting on the pawl component, the pawl component interacting with the ejector in such a way that the pawl component takes the ejector from the first opening position into the second opening position in the opening direction under the force of the charged force unit . Advantageously, the pawl component does not protrude or overhang an outside or outer contour of the device.

Advantageously, the ejector can be moved from a closed position to a first opening position by the charged energy storage and from a first opening position to a second opening position by the charged force unit. When the movable furniture part or the ejector moves from a second opening position into the closed position of the ejector in the closing direction, the energy storage and the force unit are preferably loaded.

The force unit can have different strengths or pulling forces. If the power unit is comparatively weaker, the movement of the movable furniture part is preferably guided by an operator or the power storage device. If the force unit is designed to be stronger, the force unit can be dimensioned sufficiently powerful that the movable furniture part is moved in the opening direction solely by the force unit using the ejector.

A movement of the movable furniture part in the opening direction relative to the furniture body under the action of the force unit of the device arranged on the furniture takes place over at least a partial distance from a first opening position to a second opening position, according to the Guide means for the maximum opening path provided by the movable furniture part on the furniture body.

The first opening position is horizontally spaced from the second opening position in the opening direction in the assembled state.

The opening and closing directions of the ejector correspond to the directions of movement of the pawl component, with the pawl component moving the ejector in the opening direction by the action of the force unit. In the closing direction, the ejector preferably moves the pawl component in the closing direction, whereby the power unit can be loaded.

It is advantageous that the device has a guide with a guide track, with the pawl component being movable along the guide track with a guide element.

The device preferably has a base plate on which the guide track is formed. Preferably, the guide track is recessed in the base plate towards a main plane of the base plate. The main plane of the base plate preferably extends in the longitudinal direction or in the opening direction of the ejector and in a width direction which extends perpendicular to the longitudinal direction. The guideway is preferably L-shaped in cross section in the opening and closing directions. The longer leg of the L-shape is aligned in the opening and closing direction of the movable furniture part or the ejector and the shorter leg of the L-shape is preferably aligned perpendicular to the longer leg. Advantageously, the shorter leg is aligned in the opposite direction to the ejector or is deeper in the base plate compared to the longer leg.

A longitudinal direction of the base plate is preferably aligned in the opening and closing directions of the ejector. Preferably there are two completely separate guideways designed, which are spaced apart in the width direction of the base plate, so that the pawl component can be moved with the guide element on both sides. Another possibility is that only a single guide track is present, with the guide element then only being movable on one side to support the guide track. The pawl component is advantageously positively controlled by the movement of the guide element along the guide track.

The guide element preferably has an outer contour which is moved along the guide track; the outer contour is preferably convex or semicircular.

The base plate or the device as a whole is preferably fixed in position on the guide means or on the furniture, in particular a drawer, when the device is in the assembled state.

It is also advantageous that in the assembled state of the device, a first end of the force unit is connected to the pawl component and a second end of the force unit is connected to the device.

Preferably, the second end of the power unit, which is connected to the device, is fixedly arranged on the base plate. Preferably, there is a recess in the base plate, the recess being designed to fit the second end of the power unit.

The second end of the force unit is preferably arranged further forward in the opening direction on the base plate than the first end of the force unit. The two ends of the power unit are preferably spaced apart horizontally when the device is mounted. Advantageously, the second end of the force unit is fixed in position, so that the movable pawl component is pulled with the first end of the force unit in the opening direction or in the direction of the second end of the force unit.

It is also advantageous that in the closed position of the ejector, the pawl component is covered from above by the ejector in an assembled state.

Preferably, the pawl component is completely covered from above by the ejector in the closed position. Preferably, the ejector prevents the pawl component from being movable in the opening direction by the action of the force unit when the ejector covers the pawl component. Advantageously, the pawl component is covered by the ejector until the ejector has reached the first opening position.

Advantageously, in the closed position of the ejector, the guide element of the pawl component is arranged in a first guide area of the guide track, the first guide area being recessed in the opposite direction to the ejector.

Preferably, the first guide area is the shorter leg of the L-shape. Advantageously, the first guide area is formed deeper in the depth direction of the base plate than a second guide area. Due to the deeper design of the first guide area compared to the second guide area, the guide element is arranged lower in the closed position than in the first open position, whereby the pawl component can be hidden by the ejector.

Preferably, the force unit is loaded when the guide element is arranged in the first guide area. The pawl component is advantageously held in place by the guide element being arranged in the first guide area, so that the power unit cannot be discharged in the opening direction.

It is advantageous that the guide element of the pawl component can be moved in the opening and closing directions along a second guide area of the guide track, with a longitudinal extension of the second guide area running parallel to the direction of movement of the ejector in the opening and closing directions.

The second guide area is preferably the longer leg of the L-shape. The second guide region of the guide track is preferably formed in the longitudinal direction of the base plate. Preferably, the direction of movement of the pawl component is the same as the direction of movement of the ejector. The first guide area is preferably aligned perpendicular to the second guide area. The first guide area is preferably aligned vertically when the device is assembled and the second guide area is horizontal. For example, the first management area merges into the second management area without any offsets.

If the guide element is in the second guide area, the power unit can be unloaded, whereby the pawl component and the ejector or the movable furniture part are moved in the opening direction. The movement of the pawl component along the second guide region corresponds, for example, to the movement of the ejector from the first opening position to the second opening position.

It is advantageous that the pawl component has a guide member, the guide member being permanently arranged in the second guide area of the guide track.

The guide member is designed, for example, as a bolt and is preferably present protruding from the pawl component. A guide member is preferably formed on both sides of the pawl component. The pawl component advantageously has two guide members, which are moved in a supporting manner along the guide tracks which are spaced apart in the width direction.

Preferably, the guide member is suitably coordinated for a guided intervention in the guide track. Advantageously, the guide member is guided over the entire opening and closing movement of the ejector in the second guide area, in particular guided with little play.

Preferably, in the closed position of the ejector, the guide element is arranged lower in the opposite direction to the ejector than the guide member, which is arranged in the first guide region in the closed position. When moving in the opening direction, the guide element moves from the recessed first guide area into the higher second guide area, whereby the pawl component is pivoted in the direction of the ejector. Advantageously, the guide member forms the pivot axis for deflecting or pivoting the pawl component. The pivot axis preferably runs perpendicular to the opening and closing direction of the ejector. For example, the pivot axis runs through the center of the two circular surfaces of the cylindrical guide members.

It is also advantageous that the guide track is designed in such a way that in the first opening position the guide element of the pawl component can be deflected in the direction of the ejector, so that a hook section of the pawl component comes into engagement with the ejector.

The hook section is advantageously arranged above the guide element in the direction of the ejector. Preferably, the hook section moves from the first guide area into the second guide area due to the movement of the guide element and thus into an elevated position in the direction of the ejector due to the pivoting of the pawl component.

Advantageously, an end section of the ejector can be gripped behind by the hook section in the longitudinal direction of the ejector become. The end section of the ejector is preferably arranged on an edge of the ejector in the closing direction. The end section of the ejector is preferably arranged opposite the stop element of the ejector.

It is advantageous that the pawl component moves the ejector under the action of the charged force unit along the second guide region of the guide track in the opening direction.

Because the guide element is locked from the first guide area in the opening direction into the second guide area of the guide track, the force unit can advantageously be unloaded, whereby the pawl component can be moved along the second guide area in the opening direction.

Preferably, the guide element and the guide member of the pawl component are moved along the second guide region, whereby the movable furniture part or the ejector are moved in the opening direction from the first opening position to the second opening position.

According to the invention it is provided that the ejector has a recess, with space for a connecting section of the pawl component in the recess.

Preferably, the hook section is spaced apart from the connecting section in the longitudinal direction of the ejector or in the opening direction.

The connecting section is preferably permanently arranged in the recess of the ejector. A first end of the force unit can preferably be arranged on the connecting section. The connecting section has a precisely fitting receiving contour for the first end of the power unit. Another possibility is that the base plate has a recess. Furthermore, the guide areas can be formed deeper in the base plate if the Base plate has a comparatively greater depth, so that the recess in the ejector can be omitted.

Advantageously, the recess in the ejector is groove-shaped, with the connecting section of the pawl component being movable along the length of the recess in the opening and closing directions of the ejector.

The connecting portion is preferably movable along the length of the recess in the ejector when the ejector is moved from the closed position to the first open position and back.

It is advantageous that the connecting section has a hooking contour, the hooking contour interacting with an edge contour of the recess when the ejector moves from the first opening position to the second opening position.

The connecting section preferably has a longitudinal contour which is aligned in the longitudinal direction of the ejector. Preferably, a hooking contour is formed transversely to the longitudinal contour, which runs in the opposite direction to the ejector. The hooking contour is preferably formed opposite the hook section.

The edge contour of the recess is preferably formed in the width direction of the recess, with the edge contour preferably being aligned in the direction of the closing direction.

Advantageously, the hook section rests on the end section of the ejector when the ejector moves from the first to the second opening position, the hooking contour of the connecting section resting on the edge contour of the recess during the opening movement. The hooking contour of the connecting section and the edge contour of the recess are coordinated with one another in such a way that they can fit into one another, whereby force transmission is possible.

It is also advantageous that the edge contour of the ejector and the hooking contour of the pawl component can be coupled and decoupled, the edge contour of the ejector moving the pawl component through the hooking contour during a movement in the opening direction in such a way that the movement in the opening direction moves the pawl component by means of the guide element Hook section deflects or pivots.

Because the edge contour of the ejector rests on the hooking contour of the pawl component, the pawl component can be moved by the ejector in the opening direction, for example briefly. As a result, the guide element is moved along the guide track, whereby the guide element moves from the first to the second guide area. The guide element and the hook section can be pivoted vertically upwards. The hook section engages behind the end contour of the ejector during the pivoting movement in the direction of the ejector. When the guide element reaches the second guide area, the power unit can be discharged, whereby the pawl component and the ejector are moved in the opening direction up to the second opening position.

An advantageous embodiment of the invention is a piece of furniture with a device for moving a movable furniture part according to one of the previously described embodiments relative to a furniture body. Preferably there are two devices for moving a movable furniture part on the furniture. For example, the furniture includes a furniture body and a movable furniture part arranged movably thereon. Advantageously, the device is designed to 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 which is movably guided via guide means 52 is in Figure 1 shown. The drawer 53 includes a drawer base 54, a drawer front 55, two opposite side walls 56 and a drawer rear wall 57.

To guide the drawer 53, two guide means 52 with the same effect are present 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 dashed lines) for moving or ejecting the furniture part designed as a drawer 53 in the opening direction M1 is arranged on an underside of the drawer bottom 54.

The device 1 is used to force-assisted ejection of the drawer 53 over a portion of an opening movement of the drawer 53 from a closed position relative to the furniture body 51 in the opening direction M1 of the drawer 53. The drawer 53 is via the guide means 52, for example two similar partial or full extensions , mounted on the furniture body 51 so that it 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 furniture 50.

The device includes, among other things, a base plate 3, a force unit 4, a pawl component 5, an ejector 6 and an energy storage device 7 (see Fig. Fig. 2 ). The guide track 8 is formed in the base plate 3. Furthermore, a recess 9 for receiving the movement element 10 is provided in the base plate 3, on which the energy accumulator 7 is preferably accommodated. The energy storage 7 preferably comprises two spiral springs 11, 12, each of which is attached to the movement element 10 at one end. The other ends of the spiral springs 11, 12 are advantageously connected to a bearing part 13, the length of the tensioned spiral springs 11, 12 being able to be adjusted by an operating section 14. A spring rod 15 is arranged on the movement element 10, which is preferably in a Heart curve 16, which is formed in the base plate 3, is guided. Furthermore, the spring rod 15 can be moved along a guide link 17 of the ejector 6. When the spring rod 15 moves along the guide link 17 in the ejector 6 and/or the heart curve 16 in the base plate 3, a synchronization plate 18 can also be moved. The synchronization plate 18 is connected to the base plate 3 via a spring 19.

The base plate 3 is covered by a cover element 20, the cover element 20 having a control cover 21. The cover element 20 and the control cover 21 can also be formed in one piece. The control cover 21 preferably has a further heart curve (not shown), which in the assembled state is preferably designed to be mirror-symmetrical to the heart curve 16 in the base plate 3.

The guide track 8 is designed in the base plate 3 in order to move the pawl component 5 along the guide track 8. The guide track 8 preferably has two separately designed guide tracks 8 in the width direction of the base plate, which is aligned perpendicular to the opening and closing movement of the ejector 6. The guide track 8 can be divided into two guide areas 22, 23, preferably into exactly two guide areas. The first guide area 22 is recessed in the base plate 3 in the opposite direction to the ejector 6. The second guide area 23 preferably runs along the opening direction P1 and closing direction P2 of the ejector 6. The two guide areas 22, 23 form, for example, an L-shape, with the longer leg forming the second guide area 23 and the shorter leg forming the first guide area 22.

In the Figure 3 a receptacle in the base plate 3 for a second end of the power unit 4 can be seen. The first end of the power unit 4 is connected to a connecting section 24 of the pawl component 5 (see Fig. Fig. 4 ). This points further Pawl component 5 has a guide member 25, which can preferably be moved permanently in the second guide area 23 of the guide track 8. The guide member 25 is protruding from the pawl component 5 and is preferably cylindrical or bolt-like. Preferably, there are guide elements 25 on both sides of the pawl component 5, which can be moved along the guide tracks 8 which are spaced apart in the width direction. Advantageously, the guide member 25 can be supported along the second guide area 23 of the guide track 8. The pawl component 5 also has a guide element 26, which is moved from the first guide area 22 into the second guide area 23 when the ejector 6 opens. As a result, a hook section 27 of the pawl component 5, which is located above the guide element 26 in the direction of the ejector 6, can be pivoted in the direction of the ejector 6. The pawl component 5 also has a hooking contour 28, which can interact with the ejector 6. The hooking contour 28 is preferably aligned transversely to the opening and closing direction of the ejector 6.

The ejector 6 has a recess 29 on the underside, which is aligned in the direction of the base plate 3. The depression 29 is preferably groove-shaped, with the longitudinal extent L of the depression 29 being aligned in the opening and closing direction of the ejector 6. The connecting section 24 of the pawl component 5 is accommodated in the recess 29. The recess 29 has a surface which is formed in the width direction and height, with an edge contour 30 which can be coupled and decoupled from the hooking contour 28 of the pawl component 5.

A stop element 31 is formed on the ejector 6 and interacts with the drawer 53. During the opening movement, the ejector 6 moves the drawer 53 in the opening direction P1 with the stop element 31 by the force of the charged force unit 5 and/or the force accumulator 7. During the closing movement P2, the drawer 53 presses against it Stop element 31 of the ejector 6, whereby the energy storage 7 and the power unit 5 are loaded.

In the Figure 6 the device is shown in the closed position. This is in the Figures 6 to 8 the cover element 20 is not shown for better clarity. In the Figure 6 In addition, the control cover 21 is not shown. In the Figures 7, 8 , 10, 11 , 13 and 14 the ejector 6 and the pawl component 5 are shown in section for a better view of the arrangement of the pawl component 5 in the guide track 8.

This is in the Figures 6 to 8 It can be seen that the pawl component 5 is covered from above by the ejector 6 in the closed position. The connecting section 24 of the pawl component 5 is accommodated in the recess 29 of the ejector 6, with the edge contour 30 of the recess 29 not interacting with the hooking contour 28 of the pawl component 5. The guide element 26 of the pawl component 5 is in the closed position in the first guide area 22, so that the power unit 4 is maximally tensioned. The guide member 25 is supported on the guide track 8 of the second guide area 23.

The spring bar 15 is arranged in an arc of the heart curve 16, whereby the spring bar 15 cannot be moved in the opening direction P1 because the synchronization plate 18 blocks this movement (see Fig. Fig. 6 ). By pressing the drawer 53 in the closing direction M2, the ejector 6 is moved with the movement element 10 in the closing direction P2. The movement element 10 also moves the spring bar 15 in the closing direction P2, whereby the spring bar 15 is no longer blocked by the synchronization plate 18. As a result, the energy storage device 7 is discharged and the spring rod 15 is moved along the heart curve in the opening direction P1. When the spring rod 15 moves in the opening direction P1, the synchronization plate 18 and the ejector 6 are also moved in the opening direction P1 until the first opening position is reached (see Fig. Figure 9 ). In the first opening position, the energy storage 7 is discharged.

In the Figures 10 and 11 the guide element 26 of the pawl component 5 is still in the first guide area 22 of the guide track 8 and thus the hook section 27 is not yet deflected in the direction of the ejector 6. Because the edge contour 30 of the recess meets the hooking contour 28 of the pawl component 5, the pawl component 5 is moved in the opening direction, whereby the guide element 26 is moved along the guide track 8 into the second guide region 23. The pawl component 5 can be pivoted about the guide member 25, which rests on the guide track 8 in the second guide area 23. When the pawl component 5 is pivoted, the hook section 27 can be deflected upwards in the direction of the ejector 6, with the hook section 27 engaging behind an end contour 32 of the ejector 6. As soon as the guide element 26 of the pawl component 5 reaches the second guide area 23 of the guide track 8, the power unit 4 can be unloaded. As a result, the pawl component 5 is moved in the opening direction P1. The ejector 6 is also moved in the opening direction P1 until the second opening position is reached (see Fig. Fig. 12 to 14 ). The drawer 53 is moved in the opening direction P1 by the stop element 31 of the ejector 6.

In the second opening position, the power unit 4 is unloaded. In the Figure 14 It can be seen that the edge contour 30 of the recess 29 rests on the hooking contour 28 of the pawl component 5. Furthermore, the guide member 25 and the guide element 26 are located in the second guide region 23 of the guide track 8, the guide member 25 being spaced horizontally from the guide element 26. The guide member 25 is located further forward in the opening direction P1 compared to the guide element 26.

When opening from the first opening position (see Fig. 9 ) into the second opening position (see. Fig. 12 ), the spring rod 15 is first moved along a first straight area 33 of the guide link 17 of the ejector 6. The spring rod 15 is fixedly arranged at a position on the heart curve 16. With further movement in the opening direction P1, the spring rod 15 is moved through a lateral area 34 of the guide link 17 to the right or in the direction of the force unit 4 and then moved along a second straight area 35. The spring rod 15 thus reaches the right section of the heart curve 16 (see Fig. Fig. 12 ) and the synchronization plate 18 can be pulled back into the starting position by the spring 19. When the ejector 6 closes in the closing direction P2, the spring bar 15 is first moved along the second straight area 35 of the guide link 17 until the spring bar 15 rests at the transition between the second straight area 35 and the side area 34. If the spring rod 15 is in contact with the transition, the spring rod 15 and thereby also the movement element 10 with the energy accumulator 7 can be moved in the closing direction P2 with a further closing movement of the ejector 6, the energy accumulator 7 being charged. The spring rod 15 is guided along a right, straight region 36 of the heart curve 16 until the end of this region, then the spring rod 15 follows the heart curve 16 and moves to the left in the direction of the spring 19. The spring rod 15 thus also reaches the first straight region 33 the guide link 17. The spring rod 15 is locked in the heart curve 16, whereby the spring rod 15 is moved along the first straight area 33 when the ejector 6 continues to close. With further closing movement of the ejector 6, the closed position is reached (see Fig. Fig. 6 ).

The power unit 4 is loaded directly by the contact of the hook section 27 on the end contour 32 of the ejector 6 when the ejector 6 is moved in the closing direction P2. The guide member 25 and the guide element 26 can be moved along the second guide area 23 of the guide track 8 until the guide element 26 reaches the first guide area 22 and is pivoted downward. As a result, the hook section 27 of the pawl component 5 no longer rests on the end contour 32 of the ejector 6, so that the ejector 6 can be moved relative to the pawl component 5 in the closing direction P2. The connecting section 24 of the pawl component 5 is moved along the recess 29 of the ejector 6.
