Description

Device with furniture part and furniture

Background

Devices for moving movable furniture parts, in particular devices for guided movement of movable furniture parts, which are fastened, for example, to guides or to associated furniture, are known. The known devices usually comprise an energy store, with which the movable furniture part is supported during the opening and/or closing movement relative to the furniture body. In order to eject the furniture part from the closed position in the opening direction, the device is first triggered from the ready position with the accumulator loaded in order to activate the accumulator.

Disclosure of Invention

The object of the invention is to develop a device for the assisted displacement of a movable furniture part by means of an energy store, in particular with regard to the reliable setting of a ready position of the device.

This object is achieved by the independent claims.

Advantageous and advantageous variants of the invention are indicated in the dependent claims.

The invention is based on a device for moving a furniture part in an opening direction relative to a furniture body of a piece of furniture, wherein the furniture part is movable by means of a guide in the opening direction and in a closing direction opposite to the opening direction. The device is in particular an ejector device, such as a drawer or door or flap ejector device, which has a touch-lock function for a drawer or furniture flap. The guide is preferably a known rail guide, which is designed as a partial or full extension, or as a flap fitting or door fitting. The device can be functionally coupled to or comprise an automatic retraction mechanism for the damped, force-assisted, soft or gentle retraction of the furniture part or drawer, door or flap or door into the closed position of the drawer or flap or door.

The device has a loadable accumulator and an ejector which can be driven in an opening direction by the action of the accumulator which performs a load release (enterden), wherein the accumulator is lockable in a loaded state such that, after unlocking of the loaded accumulator, a furniture part can be moved in the opening direction from a closed position on the furniture body by means of a device mounted on the furniture, wherein the ejector is kinematically coupled to the furniture part, wherein the accumulator can be loaded as the ejector is moved back in the closing direction, wherein a synchronization mechanism of the device is provided which can be coupled to a synchronization mechanism of a further corresponding device provided on the furniture for moving the furniture part in the opening direction in order to synchronize the unlocking of the loaded accumulator of the device. Synchronization is particularly relevant for the touch-lock function on a relatively wide range of furniture parts on which two identical ejection devices are present, spaced apart in the width direction. The two devices cooperate when ejecting the furniture part, wherein their accumulators together provide a cumulative total ejection force acting on the furniture part. Not activating both devices together would result in only the force of one of the two accumulators being used for ejection. This may mean, in particular in the case of a fully loaded furniture part, that the furniture part cannot be ejected.

The core of the invention is that the synchronization mechanism of the device can be reversibly shifted in the opening direction and in the closing direction, wherein after the loaded force accumulator is unlocked, the synchronization mechanism is moved from a starting position in the opening direction into a shift position, so that the synchronization means for synchronization are movable, wherein, in order to return the synchronization mechanism to the starting position, stops are provided with which a kinematic coupling can be established in the closing direction between the ejector (Auswerfier) and the synchronization mechanism, so that when the force accumulator is loaded again, coupled with the movement of the ejector in the closing direction, the synchronization mechanism is moved from the shift position or from a position between the shift position and the starting position in the closing direction into the starting position.

Thus, if the synchronization mechanism has not yet reached the starting position, the synchronization mechanism is advantageously brought back into the starting position reliably and positively controlled by means of the mechanical stop function. In this case, the ejector is moved in the closing direction and charges the accumulator. This is the case when the furniture part is closed. In this case, when the furniture part is closed, the ejector is likewise moved in the closing direction, for example mechanically firmly coupled to the closing furniture part, and thus also acts on the energy store. Preferably, the part of the device to which the ejector is coupled for movement, for example the ejector when closing the furniture part, brings the synchronization mechanism, for example, into the starting position. It may also be the case that the synchronizing mechanism only needs to be briefly actuated by the stop when a pulling force acts on the synchronizing member in the closing direction, which pulling force is then sufficient to cause the remaining movement to the starting position. For the next ejection movement, the furniture part is therefore closed and the energy store is charged, and the synchronization mechanism is in its starting position required for synchronization.

The invention solves the problem, in particular, that the movement of the synchronization mechanism from the adjustment position back to the starting position does not take place or is not complete, for example due to component tolerances, material variations or other influences, despite the presence of a retraction force, for example, caused by a restoring element, such as a restoring spring. This can occur, for example, when there is an excessive friction effect acting on the movement of the synchronization mechanism in a braking or holding manner. For a release stroke for the displacement, usually only a relatively weak force is required, for example by driving the ejector, in order to drive the synchronization mechanism from its rest position, for example caused by static friction, and thus to bring the synchronization mechanism to the starting position.

Advantageously, a reset element is provided which acts on the synchronization mechanism and provides a reset force in order to bring the synchronization mechanism into the starting position. The reset element provides a preferably permanently established reset force on the synchronization mechanism in the direction of the starting position. The reset means is preferably a reset accumulator or a tension element, such as a tension spring, for example a helical spring, which acts on the synchronization mechanism with a bias or with a pull in the closing direction. Since the restoring force is designed to be relatively weak with respect to the force accumulator with respect to the ejection movement of the furniture part, since this restoring force must be overcome by the force accumulator during the ejection process in order to eject the furniture part and therefore should form a force component as small as possible to counteract the ejection force, it usually or spontaneously happens that the restoring force is not sufficient or not always sufficient to pull the synchronization mechanism back into the starting position due to, for example, frictional forces on the synchronization mechanism. The synchronization means are therefore forced into the starting position by the stop at the latest when the furniture part and thus the ejector are moved in the closing direction. In general, after the first pressure impulse, the synchronizing means is acted upon, for example by the ejector by means of a stop, so that in particular the static friction effect is overcome, so that the restoring force provided by the restoring element is then sufficient to move the synchronizing means into the starting position solely by the action of the restoring element. Otherwise, the stop would act accordingly, for example, even at the same time an excessively high frictional resistance would have a braking effect on the movement of the synchronization mechanism to the starting position.

A permanent connection is preferably established between the resetting device and the synchronization mechanism. In addition to the stop, the reset element thus also acts to bring the synchronization mechanism into the starting position when the furniture part is closed. For example, an effective restoring force can be transmitted to the synchronization mechanism.

The reset means are advantageously designed to apply a pulling force to the synchronization mechanism in the closing direction. In this way, a force can be reliably applied to reset the synchronization mechanism, for example using a slightly pretensioned helical tension spring. The level of the pulling force is lower than the level of the ejection force of the force accumulator acting in the opening direction, preferably by a multiple. The pulling force preferably acts permanently on the synchronization mechanism in the closing direction.

Another advantage is that the stop member comprises a stop surface on the synchronizing mechanism, which stop surface is in contact with the cooperating stop surface when the ejector is moved in the closing direction. By means of appropriately matched stop surfaces, a planar contact can be achieved when the force accumulator is loaded, in order to mechanically couple or reliably drive the synchronization mechanism in the closing direction. The stop surface and the mating stop surface are preferably perpendicular to the direction of movement of the synchronization mechanism.

It is also advantageous if the stop has a projecting lug on the outer contour of a moving part which can be coupled to the ejector. The projection can be constructed simply and in a space-saving manner. The projection has, for example, a stop face transverse and perpendicular to the direction of movement of the synchronization mechanism.

An advantageous variant of the invention is that the accumulator acts on an ejector (autoito β er) which is movable in the closing direction and in the opening direction and which, after the unlocking by the loaded accumulator, carries the ejector in the opening direction. The ejector is thus moved according to the distance required for loading and unloading the accumulator. In contrast, the ejector can be moved over a greater movement distance, in particular in the opening direction, in order to move the furniture part further in the opening direction, for example after the energy store has been unloaded. A special ejector-accumulator can act on the ejector, for example in order to exert a pulling force on the ejector acting in the opening direction.

The ejector acts in particular between the ejector and the furniture part.

Advantageously, an at least temporary kinematic coupling is present between the ejector and the ejector for loading the energy store in the closing direction and for the assisted ejection of the furniture part in the opening direction.

A further advantageous variant results when the stop is configured between the ejector and the synchronization mechanism. In this way, the path length in the closing direction and/or the starting and ending points in time of the active stop can be set or determined variably.

In general or preferably, the accumulator, i.e. the accumulator for ejection, has bearing points located on the device and bearing points acting on the ejector. Other stops than the one on the synchronization mechanism are preferably present on the ejector. Viewed in the longitudinal direction of the ejector or in the direction of movement of the ejector, a stop on the ejector preferably exists on an end section of the ejector, which end section faces a positionally fixed bearing point of the accumulator.

Alternatively, the stop is configured between the ejector and the synchronization mechanism.

A further advantageous variant is that for synchronization, an elongate connecting part is connected to the synchronization mechanism in such a way that a displacement of the synchronization mechanism in the opening direction causes a rotational movement of the connecting part in the first rotational direction. The linear movement of the synchronization mechanism is converted into a rotary movement of the connecting part by means of a suitable transmission. The connecting elements are preferably connected with their opposite ends in a kinematically coupled manner to one of the two synchronization means. In this case, the connecting element spans the gap between two devices on the piece of furniture. In this way, when the ejector is moved, a preferably linear movement of the synchronization means (which executes it) can be reliably transmitted via the rotary connecting element to a corresponding synchronization means on the furniture part on the other or another device which corresponds to the device, in order to unlock the loaded accumulator. The rotation of the connecting element causes a linear movement of the other synchronization means in the opening direction and thus simultaneously unlocks the other energy store on the other device. The two force accumulators then together and synchronously produce their force action on the furniture part in the opening direction. As a result, the furniture part is reliably ejected by the cumulative force of the two force accumulators. By means of the inherently rigid connecting element, the simultaneous transmission of motion eliminates the triggering of a trigger latch when the furniture part is pressed in the triggering or access region of only one device, which would otherwise normally mean that the other device is not triggered or the other energy store is not unlocked.

The movement of the synchronization mechanism in the closing direction results in a rotational movement of the connecting part in the second rotational direction, which is the case, for example, when resetting the synchronization mechanism in the closing direction. The force action of the restoring element or the entraining movement performed by the synchronization slide is thereby advantageously also synchronized by the stop.

Advantageously, the device has a touch-lock function for unlocking the loaded energy store. This is a validated and user-friendly design. Advantageously, no gripping element for pulling is required on the outside of the furniture part for opening the furniture part, since a pressing operation of the furniture part from the outside in the case of the touch-lock function is sufficient for triggering and unlocking the ejection of the energy store and for subsequently closing the furniture.

The invention is also realized as a piece of furniture having a furniture body and a furniture part which can be moved relative to the furniture body by means of a guide, wherein a device according to any of the above-described designs is present.

If the guide is configured as a hinge, for example as a flap fitting or door hinge, the piece of furniture is drawer furniture or furniture with pivotable flaps or doors.

Detailed Description

Fig. 1 shows a piece of furniture 50 with a box-shaped furniture body 51 and a drawer 53, which is guided displaceably by a guide 52. Drawer 53 includes a drawer bottom 54, a drawer front 55, two opposing side walls 56, and a drawer rear wall 57.

For guiding the drawer 53, two guides 52 having the same function are respectively present between each side wall 56 of the drawer 53 and the associated body side wall 58. On the underside of the drawer bottom 54, two identical devices 1, 2 according to the invention are arranged (shown in dashed lines), which together and synchronously serve to move or push out a furniture part designed as a drawer 53 in the opening direction M1.

The device 1 serves for force-assisted ejection of the drawer 53 from the closed position in the opening direction M1 of the drawer 53 relative to the furniture body 51 along a partial distance of the opening movement of the drawer 53. The drawer 53 can be movably arranged on the furniture body 51 in an opening direction M1 and in an opposite closing direction M2 by means of a guide 52, for example two identical partial or full extensions. The device 1 may alternatively be arranged on the furniture body 51 or on the guide 52 of the furniture 50.

The same applies to the device 2, in particular to the device 1 below.

The device comprises as essential main components a base plate 3, a force unit 4, a latching member 5, an ejector 6 and an accumulator 7 (see fig. 2). In the base plate 3, guide rails 8 are formed. A recess 9 is also provided in the base plate 3 for receiving a moving part 10, on which the energy store 7 preferably acts. The moving part 10 may also be referred to as an ejector. The energy store 7 comprises at least precisely one helical spring 11, preferably two

helical springs

11, 12 which can each be used individually and are each fastened at one end to the moving part 10. The other end of the

helical springs

11, 12 is advantageously connected to a support part 13, wherein the length and thus the pretensioning force of the tensioned

helical springs

11, 12 can be adjusted by means of an actuating section 14. On the moving part 10, a spring rod 15 is arranged, which is guided with a curved end section preferably within a cardioid curve 16 formed in the base plate 3. Furthermore, the elastic rod 15 is movable along a guide runner 17 of the ejector 6. During the movement of the spring rod 15 along the guide slot 17 in the ejector 6 and/or the cardioid section 16 in the base plate 3, a synchronization mechanism designed as a synchronization plate 18 moves together. The synchronization plate 18 is linearly movable in directions P1 and P2. The synchronizing plate 18 is connected to the base plate 3 by means of springs 19. When the synchronization plate 18 moves, the synchronization element 18a is in rotation D1, the direction of rotation depending on the movement of the synchronization plate 18 in the direction P1 or P2. The other end of the synchronization element 18a, which is not shown in fig. 15 to 17, is connected to the other device 2 or to the synchronization plate 18 of the device 2.

The base plate 3 is covered by a covering part 20, wherein the covering part 20 forms a mating plate which corresponds approximately to the base plate 3, so that the interior of the device 1 is closed on both sides and on the peripheral narrow sides, wherein the respective regions are open to the outside.

The cover part 20 has control caps 21 which are formed in two parts or integrally with each other. The control cover 21 preferably has a further cardioid curve (not shown) which in the assembled state preferably provides a guide rail corresponding to the cardioid curve 16 for the further angled end of the spring rod 15 in the base plate 3. This makes it possible to reliably guide the spring rod end of the spring rod 15 on both sides.

A guide rail 8 is designed in the base plate 3 in order to move the latching member 5 along the guide rail 8. The guide 8 preferably has two separately designed guide rails 8 in the width direction of the base plate, which is oriented perpendicularly to the opening and closing movement of the ejector 6. The guide rail 8 can be divided into two

guide areas

22, 23, preferably into exactly two guide areas. The first guide region 22 is formed in the base plate 3 so as to be recessed from the planar side of the ejector 6. The second guide area 23 preferably extends in the opening direction P1 and the closing direction P2 of the ejector 6. Direction P1 is associated with direction M1 and direction P2 is associated with direction M2.

The two

guide regions

22, 23 oriented at an angle to one another, for example, together form an L-shape, with the longer leg forming the second guide region 23 and the shorter leg forming the first guide region 22.

In fig. 3, a receptacle for the second end of the force unit 4 in the base plate 3 can be seen. The first end of the force unit 4 is connected with a connecting section 24 of the latch member 5 (see fig. 4). The latching member 5 also has a guide means 25 which is preferably permanently movable in the second guide region 23 of the guide rail 8. The guide means 25 protrudes at the latch member 5 and is preferably cylindrical or in the form of a bolt. There are preferably guide means 25 on both sides of the latching member 5, which are movable along the width-wise spaced apart guide rails 8. Advantageously, the guide means 25 can be moved supported along the second guide region 23 of the guide rail 8. The latching member 5 also has a guide part 26 which moves from the first guide region 22 into the second guide region 23 during the opening movement of the ejector 6. As a result, the hook section 27 of the latch member 5 above the guide part 26 in the direction of the ejector 6 can be pivoted in the direction of the ejector 6. The latch member 5 also has a hook-shaped profile 28 capable of interacting with the ejector 6. The hook-shaped profile 28 is preferably oriented transversely to the opening and closing direction of the ejector 6.

The ejector 6 has a recess 29 on the bottom surface directed to the substrate 3 (see fig. 5). The recess 29 is preferably groove-shaped, wherein the longitudinal extension L of the recess 29 is directed in the opening and closing direction of the ejector 6. The connecting section 24 of the latching member 5 is preferably received in the recess 29. The recess 29 has a surface formed in the width direction and height with an edge profile 30 that can be coupled and decoupled with the hook profile 28 of the latch member 5.

A stop element 31 is formed on the ejector 6, which stop element interacts with a drawer rail of the drawer 53 or of the guide 52. After the loaded, latching-retaining accumulator 7 has been unlocked, the ejector 6 is moved in the opening movement of the moving part 10 and, via the stop part 31, moves the drawer 53 in the opening direction P1 by means of the force of the loaded force unit 4 and/or accumulator 7. During the closing movement P2, the drawer 53 or a section of the drawer rail presses against the stop element 31 of the ejector 6, thereby loading the moving part 10 or the ejector and thus the force store 7 and the force unit 4 acting on the ejector.

In fig. 6, the device is shown in the closed position. For clarity, the cover portion 20 is not shown in fig. 6-8. In addition, the control cover 21 is not shown in fig. 6. In fig. 7, 8, 10, 11, 13 and 14, the ejector 6 and the latch member 5 are only partially shown in order to better see the arrangement of the latch member 5 in the guide rail 8.

As can be seen from fig. 6 to 8, the latching member 5 is covered from above by the ejector 6 in the closed position. The connecting section 24 of the latching member 5 is received in a recess 29 of the ejector 6, wherein an edge profile 30 of the recess 29 does not interact with the hook profile 28 of the latching member 5. The guide means 26 of the latch member 5 in the closed position are in the first guide region 22, so that the force unit 4 is maximally tensioned. The guide means 25 are supported on the guide rail 8 of the second guide area 23.

The spring bar 15 is arranged in an arcuate section of the cardioid section 16, wherein the spring bar 15 cannot move in the opening direction P1 because the synchronization plate 18 blocks this movement (see fig. 6). The device 1 has reached the zero position, the drawer 53 resting on the furniture body 51 in the closed position.

The drawer 53 is intentionally opened or ejected from the outside by a user who uses the touch lock function and pushes the drawer 53 or the drawer front 55 of the drawer 53 inward in the closing direction M2, thereby causing the ejector 6 to move in the closing direction P2 along with the moving member 10. By means of the moving part 10, the spring lever 15 is also moved in the closing direction P2, whereby the spring lever 15 is no longer blocked by the synchronization plate 18. The spring ends enclose an end face of the synchronizing plate 18, which end face is now movable in the opening direction P1. The force accumulator 7 is therefore relieved of load, and the spring lever 15 moves along the cardioid curve and the flank on the synchronization plate 18 in the opening direction P1. When the elastic rod 15 moves in the opening direction P1, the synchronizing plate 18 and the ejector 6 also move in the opening direction P1. The drawer 53 is moved or ejected. And then reaches the first open position (see fig. 9). In the first open position, the accumulator 7 is unloaded.

In fig. 10 and 11, the guide part 26 of the latching member 5 is still in the first guide region 22 of the guide rail 8, so that the hook section 27 has not yet been deflected in the direction of the ejector 6. By the edge contour 30 of the recess hitting the hook contour 28 of the latch element 5, the latch element 5 is moved in the opening direction P1, whereby the guide part 26 is moved along the guide rail 8 into the second guide area 23. The latching member 5 can pivot about a guide means 25 which rests on the guide rail 8 in the second guide region 23. When the latching member 5 is pivoted, the hook section 27 can be deflected upwards in the direction of the ejector 6, wherein the hook section 27 barbs the end profile 32 of the ejector 6. As soon as the guide part 26 of the latching member 5 reaches the second guide region 23 of the guide rail 8, the force unit 4 can be unloaded. Thereby causing the latch member 5 to move in the opening direction P1. Since the hook section 27 of the latch member 5 barbs the ejector 6, the ejector 6 is also moved in the opening direction P1 until the second opening position is reached (see fig. 12 to 14). The drawer 53 is moved in the opening direction P1 by the stopper member 31 of the ejector 6.

In the second open position, the force unit 4 is unloaded. In fig. 14 it can be seen that the edge profile 30 of the recess 29 rests on the hook profile 28 of the latching member 5. Furthermore, the guide means 25 and the guide part 26 are located in the second guide region 23 of the guide rail 8, wherein the guide means 25 is horizontally spaced apart from the guide part 26. The guide mechanism 25 is further forward in the opening direction P1 than the guide member 26.

During the opening movement from the first open position (see fig. 9) to the second open position (see fig. 12), the elastic rod 15 first moves along the first rectilinear area 33 of the guide chute 17 of the ejector 6. The elastic rod 15 is fixedly arranged according to the position on the cardioid curve 16. With further movement in the opening direction P1, the spring lever 15 is moved to the right or in the direction of the force unit 4 by the lateral region 34 of the guide runner 17 and then along the second linear region 35. The spring rod 15 thus reaches the right-hand section of the cardioid curve 16 (see fig. 12), and the synchronization plate 18 can be pulled back into the starting position by the spring 19.

During the closing movement of the ejector 6 in the closing direction P2, i.e. in particular when the drawer is pushed up by the user to close and the drawer carries the ejector 6 along the closing direction P2, the spring rod 15 is first moved along the second linear region 35 of the guide link 17, possibly assisted by an automatic retraction mechanism providing a force-acting damping, until the spring rod 15 abuts on the transition between the second linear region 35 and the lateral region 34. When the spring lever 15 abuts against the transition, then, in a further closing movement of the ejector 6, the spring lever 15 and thus also the moving part 10 can be moved in the closing direction P2 by means of the energy store 7, wherein the energy store 7 is loaded. Here, the elastic rod 15 is guided along a section 36 running straight along the right side of the cardioid curve 16 up to the end of this section 36, and then the elastic rod 15 follows the cardioid curve 16 and moves to the left in the direction of the spring 19. The spring lever 15 therefore also reaches into the first linear region 33 of the guide link 17. The spring lever 15 is locked in the cardioid curve 16, whereby the spring lever 15 moves along the first linear region 33 during a further closing movement of the ejector 6. In a further closing movement of the ejector 6, the closed position is reached (see fig. 6).

When the ejector 6 is moved in the closing direction P2, the force unit 4 is directly loaded by the hook section 27 abutting against the end contour 32 of the ejector 6. The guide means 25 and the guide part 26 can be moved along the second guide region 23 of the guide rail 8 until the guide part 26 reaches the first guide region 22 and pivots downward. In this way, the hook section 27 of the latching member 5 no longer abuts against the end contour 32 of the ejector 6, so that the ejector 6 can be moved relative to the latching member 5 in the closing direction. Here, the connecting section 24 of the latching member 5 moves along the recess 29 of the ejector 6. If the synchronizing plate 18 is not pulled in the closing direction P2 by the tensioned spring 19, the stop on the displacement part 10 comes into contact with the counter stop on the synchronizing plate 18 when the accumulator 7 is loaded. Thereby returning the synchronization plate 18 to its starting position.

Fig. 15 shows that there is a stop 37 with a stop surface 38 on the moving part 10 or ejector and a stop surface 39 on the synchronization plate 18. According to fig. 15, the two stop faces 38 and 39 are spaced apart or spaced apart from each other by a few millimeters in the direction of movement of the moving element 10 or in the direction P1 or P2. This is because the synchronization plate 18 is retracted in the starting position and is ready for the synchronization process due to the tensile spring force of the spring 19 which becomes active.

The stop 37 has a projecting projection 10a on the outer contour of the moving part 10 that can be coupled with the ejector 6.

The synchronizing plate 18, which is movable to and fro in the directions P1 and P2, is moved into the starting position according to fig. 15 by a tensile force F1 (see fig. 15) exerted by a spring 19, for example a helical spring, on the synchronizing plate 18 in the direction P2.

Fig. 16 and 17 show the driving contact between the stop surfaces 38 and 39, as shown in fig. 16 and 17, when the synchronization plate 18 is in the adjustment position despite the spring 19, i.e. remains in this adjustment position or is jammed after the synchronization movement. This can occur, for example, as a result of friction effects if the force of the spring 19 is not sufficient to return the synchronization plate 18 from the adjusted position shown in fig. 16, 17 to the starting position, for example, as a result of static friction. When the drawer 53 is closed and the ejector 6 is thereby moved and the moving part 10 is moved in the direction P2, the moving part 10 brings the synchronization plate 18 together up to the starting position. Here, the stop surface 38 presses against the stop surface 39 and pushes the synchronization plate 18 in the direction P2. The synchronization plate 18 is forced back to the starting position with the aid of the force F1.

Thereafter, with the drawer stationary closed, the synchronization plate 18 is in the starting position. Then, the next time the closed drawer is operated, the synchronization plate 18 can be moved along with the unlocking of the loaded accumulator 7 by means of the touch-lock function.

Without the stop 37, it cannot be reliably ruled out that the synchronization plate 18 remains in the adjusted position and that no synchronization takes place during the next touch-lock.
