    专利说明:

    The invention relates to a drive device for a movable furniture part, comprising two, arranged on opposite sides of the movable furniture part ejection devices for ejecting the movable furniture part from a closed position to an open position, wherein the ejection devices each have a spring-loaded locking element for locking the ejection device in a locking position, a guideway with an angled end portion, wherein the locking element is locked in the angled end portion in the locking position, and a separate locking element unlocking element by which the locking element is releasable in overpressure of the movable furniture part in a behind the closed position Überdrückstellung from the angled end portion. Moreover, the invention relates to a piece of furniture with such a drive device.
    Such a drive device is apparent from DE 10 2010 061 482 A1. This is mainly about the opening and closing operation of a movable furniture part, wherein the locking of the ejection device takes place in an angled end portion of a guideway. A disadvantage of this known opening and closing device or drive device is that, especially when used in wide drawers by unilateral release or overpressure of the drawer tilting and unilateral unlocking can occur. This can lead to an undesirable jamming of the drawer in the furniture body.
    An object of the present invention is therefore to avoid these problems. Therefore, the present invention also relates to a synchronization device.
    In general, various synchronization devices are already known from the prior art. A first example of synchronized ejection devices is shown in EP 1 314 842 B1, in which the release levers are connected without play and synchronously with one another. On this Ausrückhebeln the locking projections - which form the locking element - arranged. These latching projections are in a pawl - which is a kind of guideway for the
    Locking projections form - locked. An unlocking of the latching projection from the pawl takes place during overpressing by a relative movement of these two parts to each other. There is no separate from the pawl or locking projection unlocking.
    Another lockable ejection device with a synchronization unit is disclosed in WO 2009/114884 A2. In this case, a projection formed on a receiving element can be moved and locked in a heart-shaped cam track. Also in this embodiment, the unlocking is performed by a relative movement of these two components to each other during overpressing, after which relax an ejection force storage and eject the movable furniture part in the opening direction.
    In the case of EP 2 429 339 B1, too, the locking takes place via a heart-shaped cam track, wherein a latching element mounted on a movable carriage engages in the heart-shaped cam track. Again, the unlocking is done by a relative movement of the latching element to the heart-shaped slide track. The synchronization takes place by a movement coupling of the linearly movable slides.
    Another such locking is disclosed in WO 2013/059847 A1.
    In contrast, DE 20 2009 005 255 U1 shows a synchronization without a concrete mechanical synchronization unit. Rather, in this case, the synchronization takes place by a power transmission via the drawer to the other side, so that the not yet triggered locking element is triggered by the double-acting force of the ejection energy storage in the pulling direction. Here, too, the unlocking thus takes place by a relative movement of a switching element to the switching curve.
    Another synchronization method is apparent from the unpublished, Austrian patent application A 785/2013. Here is a
    Synchronization performed only after the overpressing movement by a part of the guideway of the unlocked ejection device is moved at the already started ejections on the other ejection device via the synchronization device, whereby the latched in a detent recess locking pin can move out of this detent recess of the heart-shaped slide track. Here, too, therefore, unlocking by a relative movement between heart-shaped slide track and locking pin.
    Now, if a skilled person is confronted with the task of implementing a known synchronization device in the known DE 10 2010 061 482 A1, he could refer to the prior art instructions, for example, the movements of the locking elements, the movements of the ejector devices or the movements of a To synchronize part of the guideway of the two ejector devices.
    According to the invention the object is - to prevent an inclination of the drawer in a drive device according to DE 10 2010 061 482 A1 - but solved in that the unlocking of the two ejection devices are synchronized with the synchronization device.
    Thus, a synchronization option is created, which just does not appear obvious from a combination of the fonts shown, especially since it is in the entire, known from the prior art, synchronization devices no separate from the locking element and the guideway unlocking.
    Further preferred embodiments are specified in the subclaims.
    For example, it is preferably provided that each ejection device has a housing. For a simple embodiment it is provided that the guideways are each formed in the housing. For a simpler ejection movement, the guideways each have an ejection section in addition to the angled end section.
    In principle, the unlocking elements can be linearly movable. Particularly preferably, however, it is provided that the unlocking elements are each movable, preferably pivotally mounted on the housing.
    A synchronization of the unlocking can be done for example via a rotatable synchronization rod z. B. combing formed at the end of the rotatable synchronization rod sprockets with trained on the unlocking racks. Preferably, however, it is provided that in each case two bearing points are formed on each unlocking element and are rotatably mounted on these bearings synchronization rods of the synchronization device. Particularly preferably, these synchronization rods are arranged crossed, so that a rotational movement of the one unlocking element is converted into an opposite rotational movement of the other unlocking element. For a simple guidance of the locking elements, it is provided that the locking elements are each mounted so as to be displaceable in the guideway via two peg-shaped extensions.
    In principle, the drive device can only consist of the two ejection devices and the synchronization device. But for even more diverse applications is preferably additionally a retraction device for, preferably damped, retraction of the movable furniture part provided from an open position to the closed position.
    Protection is also desired for a piece of furniture with a furniture body, a movable furniture part and a drive device according to the invention. In such furniture, the drive device may be associated with the furniture body. D. h., The two drive devices are on opposite sides of the movable furniture part z. B. attached directly to the furniture body or on a carcass rail of a pullout guide. However, it is preferably provided that the
    Drive device is arranged on the underside of the movable furniture part, wherein each ejection device can be coupled via an ejection slide in sections with a body-fixed driver. D. h., The drive device abuts, so to speak, even on these corpus fixed drivers. In these embodiments, the retractor may be integrated into the pull-out guide.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:
    1a is a piece of furniture with a movable furniture part and a drive device,
    FIG. 1b shows a movable furniture part with a drive device FIG. 2 shows an exploded view of a drive device, FIG.
    3 shows a 3D view of the assembled drive device and FIGS. 4 to 14 show the functional sequence of the movements of the drive device in each case in a plan view.
    Fig. 1a shows a furniture 15 with a furniture body 16 and two movable furniture parts 2 in the form of drawers. These drawers each have a drawer container 22 and a front panel 21. The movable furniture parts 2 are movably mounted on pull-out guides on the furniture body 16. These extension guides comprise at least one carcass rail 19 and a drawer rail 20. On the underside of the movable furniture part 2, a drive device 1 is arranged. This comprises two arranged on opposite sides of the movable furniture part 2 ejection devices 3 and a synchronization device 8. On the body rails 19 drivers 18 are arranged.
    In Fig. 1b, the underside of the movable furniture part 2 with the at least partially mounted on the movable furniture part 2 driving device 1 is shown. This drive device 1 also has a arranged in or on the pull-out
    Pulling device 14 for pulling the movable furniture part 2 from an open position OS in a closed position SS. In this embodiment, the retraction device 14 is mounted on the drawer rail 20 and can be coupled to a arranged on the carcass rail 19 driver 38. In addition, the attachment of the driver 18 on the carcass rail 19 via a retaining plate 37 can be seen.
    In Fig. 2, the drive device 1 is shown in a partial exploded view. As already seen in this Fig. 2, the two ejection devices 3 are each formed mirror-symmetrically. In principle, of course, slight differences between the two drive devices 3 could be given. For a simpler production, however, they are identical or exactly mirror-symmetrical. Each of these ejection devices 3 has a housing 9 which can be mounted on the movable furniture part 2. In this housing 9, the guide track 5 is formed with the ejection section 10 and the angled end section 6. In addition, the guide track 30 for the projection 29 formed on the locking element 4 and the guide track 25 for the ejection slide 17 are formed in the housing 9. The ejection slide 17 is linearly movable along this guide track 25. The ejection slide 17 has the coupling extension 23, via which the ejection devices 3 can each be coupled to the body-fixed drivers 18. At the ejection slide 17 each locking lugs 27 are movably mounted via a compression spring 28. The locking element 4 is movably mounted in the guideway 5 via the two extensions 13. The other extension 29 of the locking element 4 engages in the guide track 30. On the one hand on the extension 29 of the locking element 4 and on the other hand on the spring base 33 formed on the housing 9 of the ejection force accumulator 24 designed as a tension spring is held. The unlocking elements 7 are formed separately from the guideways 5 and 4 of the locking elements. The unlocking elements 7 are also movable relative to the guide tracks 5 and locking elements 4. In the formed in the housing 9 recesses 35, the unlocking elements 7 are rotatably supported via pivot bearings 31. Furthermore, in each case the bearing points 11 are formed in the unlocking elements 7, in which engage the extensions 32 of the synchronization rods 12.
    These synchronization rods 12 form with the projections 32 formed thereon in cooperation with the bearing points 11 on the unlocking elements 7, the synchronization device 9. The damping element 26 serves for gentle braking or damping of the ejection movement of the locking element 4th
    In Fig. 3, the drive device 1 is shown in the assembled state with relaxed ejection force accumulator 24. As can be seen, the two synchronization bar 12 are arranged at different heights crossed.
    The plan view of the drive device 1 according to FIG. 4 corresponds to the 3D representation according to FIG. If this drive device 1 is arranged on the underside of the movable furniture part 2, according to FIG. 4, there is still no contact with the schematically illustrated carriers 18 which are shown schematically. The movable furniture part 2 is thus in the open position OS.
    When the movable furniture part 2 is moved manually in the closing direction SR, starting from the position according to FIG. 4, the coupling extensions 23 of the two ejection carriages 17 come into contact with the drivers 18. Since these drivers 18 are stationary, the ejection carriages 17 become relative to the Casing 9 proceed. Since the locking elements 4 rest against the lugs 34 formed on the ejection slide 17 locking lugs 27, the locking elements 4 are moved along the guideways 5 relative to the housings 9. Since the ejection force accumulators 24 are held on the extensions 29 of the locking elements 4, the ejection force accumulators 24 are tensioned in the closing direction SR during this movement.
    In Fig. 6, this clamping process has continued. The movable furniture part is still in an open position OS.
    According to FIG. 7, the movement of the movable furniture part 2 has continued in the closing direction SR, so that the locking elements 4 reach the angled end sections 6 of the guideways. When the angled end sections 6 are reached, the two locking elements 4 each contact the unlocking elements 7, so that these unlocking elements 7 rotate correspondingly about the pivot bearings 31. These rotational movements of the unlocking elements 7 are synchronized via the synchronization device 8.
    In Fig. 8, the locking elements 4 have reached the end of the angled end portion 6 of the guideways 5. As a result, the locking elements 4 are held in the guideway 5 due to the inclination and the friction of the extensions 13. The ejection force accumulators 24 thus can not relax. In this position, the locking elements 4, the two ejection devices 3 are each in the locking position VS. According to this FIG. 8, the two ejection carriages 17 have already moved further in the closing direction SR due to a retraction device 14, not shown here, until the closed position SS of the movable furniture part 2 has been reached. In this closed position SS, the latching lugs 27 abut respectively on projections 36 of the unlocking elements 7.
    If, starting from this closed position SS according to FIG. 8, the movable furniture part 2 is pushed over in the closing direction SR, the movable furniture part 2 enters an overpressure position ÜS according to FIG. 9. In this overpressure position ÜS, the ejection carriages 17 become due to the interaction with the body-fixed drivers 18 moved even further relative to the housings 9, so that about the locking lugs 27, the unlocking elements 7 are rotated about the projections 36 about the pivot bearing 31. Should be pressed on one side only on the movable furniture part 2 in this override, so the unlocking element 7 is actively moved or rotated by the locking lug 27 only on this page. On the other side, however, there is also a movement of the unlocking 7 and that by the motion synchronization on the two synchronization rods 12. With this caused by the overpressure rotational movement of the two unlocking 7 both locking elements 4 are substantially simultaneously and thus synchronously from the angled end sections 6 moves or released. Thus, the locking position VS is released, the locking elements 4 are no longer held in the angled end portions 6 and the two ejection force memory 24 can begin to relax.
    By this ejecting operation shown in Fig. 10, the locking member 4 is moved along the ejection portion 10 of the guide track 5. About the nose 34 and the ejection slide 17 is taken, so that the ejectors 3 repel the corpus fixed drivers 18. As a result, the movable furniture part 2 is moved in the opening direction OR, so that the movable furniture part 2 again enters an open position OS. Simultaneously with this ejection movement, a retraction device 14, not shown, can be loaded.
    In Fig. 11, this ejection process is already more advanced, but not yet completed.
    In Fig. 12, the ejection operation is completed and the ejection force accumulators 24 have been released. At the end of the ejection movement 24, the locking elements 4 abut against the damping elements 26. By the momentum or by a manual further movement of the ejection slide 17 are further moved along the guideways 25, whereby the locking lugs 27 come into contact with the lugs 34 of the locking elements 4.
    Against the force of the compression springs 28, the locking lugs 27 are then moved relative to the ejection slide 17 (see Fig. 13).
    In Fig. 14, the movements of the ejection slide 17 are completed and the locking lugs 27 have the lugs 34 run over. The ejection devices 3 are no longer on the coupling extensions 23 to the body-fixed drivers 18, so that the movable furniture part 2 is in an open position OS, in which the movable furniture part 2 can be moved freely by hand. It is again the starting position shown in FIG. 4 reached.
