Definitions
- the invention relates to an arrangement with a first drive device for moving a movable furniture part, a second drive device for moving the same movable furniture part and a synchronization device for synchronizing the two drive devices, wherein by two drive devices different positions during movement of the movable furniture part are receivable.
- the invention relates to a piece of furniture with such an arrangement.
- two drive devices are often provided on opposite side areas of the drawer or of the furniture carcass in order to reliably detect a pressing on the drawer at any desired location.
- problems such as a misalignment of the drawer or a jamming or wedging can occur.
- Examples of such synchronous drive devices are the EP 2 429 339 B1 , the CN 103 479 106 A the WO 2009/114884 A1 , the EP 1 314 842 B1 and the AT 008 882 U1 , In these devices, the entire unlocking process and also a part of the ejection process are synchronized.
- a synchronization shows the WO 2013/059847 A1 , in that it is all about that the lock - and not the unlocking - runs synchronously on both sides to ensure a safe and trouble-free closing.
- Another example of a synchronization shows the EP 3 128 871 B1 , according to which it is all about the fact that the release - and not the lock - runs synchronously on both sides.
- a synchronization device for a movably mounted furniture part known.
- a synchronization rod has two partial waves, between which an overload device is arranged.
- a rotational movement between the two partial waves is released.
- the synchronization rod is brought from an operating position to an overload position. In this overload position no motion transmission or synchronization is possible. This is only possible again when the spring-loaded detent part, which is disengaged in the event of overload, correctly engages again in one of the partial shafts, in which case the original relative position of the two partial shafts is again given to one another.
- a generic arrangement is from the unpublished, Austrian patent application AT 514,865 (Application No. A 785/2013 ). Since not all movements of the components (ejection slide, transmission elements, control levers, etc.) of the drive devices are constantly synchronized, it may happen that the two drive devices of the arrangement are in mutually different positions. This can cause the two drive devices do not perform the movements together (synchronously). Thus, no secure locking and no common ejection are possible. The drawer can not be operated as intended.
- the object of the present invention is therefore to provide a comparison with the prior art improved arrangement.
- the reliability should be improved.
- a correction device is provided, with which the two drive devices are brought into the same position. In other words, it is guaranteed by the correction device that both drive devices are in the same position in the movement sequence of the drive device or return to the same position.
- the correction device can be designed such that it detects a misalignment by means of a corresponding electronic detection device and triggers a correction movement of one of the drive devices on the basis of a corresponding signal. This can be done independently of the respective position of the movable furniture part. That is, the correction device automatically detects whether a malposition is given within the arrangement and triggers a corresponding correction movement. Preferably, however, it is provided that during the movement of the movable furniture part by the correction device, the two drive devices can be brought into the same position. Particularly preferably, the triggering of the correction device takes place by the movement of the movable furniture part.
- the drive devices are brought by the correction device. It is preferably provided that the drive devices can be brought by the correction device in the locking position at the end of the locking portion.
- the correction device can in principle be part of the drive devices.
- position monitoring could be performed by a position sensor. Based on a corresponding signal, the movement of one of the drive devices is then inhibited until the second drive device reaches the same position.
- a purely mechanical correction device is provided.
- the correction device is part of the synchronization device.
- the synchronization device has a synchronization rod with a first rod part and a second rod part which can be rotated relative to the first rod part, wherein the two rod parts also form the correction device. About the rotation of the rod parts to each other thus the malposition of the drive devices is corrected.
- this can take place in that the two rod parts to each other have a first operating position, in which a certain holding torque between the two rod parts is given and the two rod parts to each other have a second, rotated to the first operating position operating position.
- the holding torque between the two rod parts is substantially equal to the holding torque in the first operating position.
- the synchronizing device is directly connected to a part (eg, the ejecting carriage) of the respective driving device.
- the synchronization device has a first coupling element for connecting the synchronization device to the first drive device and a second coupling element for connecting the synchronization device to the second drive device, wherein the coupling elements are connected in a transfer-transmitting manner via the synchronization rod.
- This movement is preferably carried out in that the coupling elements and the synchronization rod each have a formed on the respective coupling element rack and a the Synchronization rod mit brieflyendes gear - wherein rack and gear mesh with each other - are connected.
- the coupling elements are each limitedly movable by a preferably resilient stop.
- the stop can be part of a housing.
- the coupling elements in turn are preferably movable on this housing, in particular rotatable, mounted.
- the rod parts of the synchronization rod prevent movement of the second coupling element to the first coupling element by rotating the rod parts to each other.
- the first coupling element can not move and unwanted moving further of the associated drive device in a further position is inhibited.
- the rotation and thus the correction by the correction device is triggered by a rotational movement between the first and second rod part occurs when the force - in the form of holding torque - between the two rod parts is smaller than the force that stops the movement of the Opposite coupling element.
- the stop is compliant, for example, as a leaf spring or as an elastic arm is formed.
- the two coupling elements, the stops of the coupling elements and the mutually rotatable rod parts form the correction device.
- the first rod part can be inserted into the second rod part, wherein the holding torque between the Bar parts - regardless of a depth of insertion of the first rod part in the second rod part - remains substantially the same size.
- the drive devices For the design of the drive devices is first to mention that they need not be identical or functionally identical. For a simple mass production but is preferably provided that the drive devices are formed substantially mirror-symmetrical.
- the drive devices each have a lockable ejection device for ejecting the movable furniture part from a closed position to an open position and a locking device for locking the ejection device in a locking position, wherein by an over-pushing movement of the movable furniture part in a behind the closed position Kochdrück ein the ejection device can be unlocked from the locking position.
- the first ejection device comprises a housing, an ejection slide movable on the housing, an ejection force accumulator acting on the ejector carriage, and a control lever movably mounted on the ejection carriage, preferably rotatable, and the first locking device is a control lever Catching element and a locking element, on which rests the latching element in the locking position.
- the latching element is movable in the overpressure movement from the locking position into an overpressing section and is movable by an ejection section during the opening movement of the ejection force accumulator, wherein the locking element is movable by the latching element moved in the ejection section in the opening direction. That is, when the locking element is no longer in the locking position, the locking element can move the locking element.
- the locking can be done via known touch-latch mechanisms.
- the first drive device has a heart-shaped cam track for the latching element, with a clamping portion formed in the housing for clamping the ejection force accumulator, a locking portion, wherein the locking element mit specify the locking portion formed in the housing overpressure portion and formed in the housing ejection section.
- the locking element is connected to the synchronization device.
- a particularly simple arrangement with few components results when the locking element is formed integrally with the synchronization device or with at least part of the synchronization device.
- the locking element on the housing movable, preferably rotatable, is mounted.
- the locking element has a locking surface on which the latching element in the locking position, and a synchronization surface on which the latching element rests in the opening direction during movement through the ejection section.
- the locking surface is substantially tangential to the direction of rotation of the Aligned locking element and the synchronization surface is aligned substantially radially with respect to the axis of rotation of the Verrieglungselements. That is, by applying force to the locking surface no rotation of the locking element - and thus no synchronization - can be triggered. Only by the application of force to the synchronization surface can be done the rotation and thus synchronization movement.
- the locking element is part of the coupling element.
- the locking element is formed integrally with the coupling element of the synchronization device.
- Protection is also desired for a piece of furniture with a furniture body, a furniture part movably mounted on the furniture body, and an arrangement according to the invention.

- the transmission element 20 can be moved along the control path 24 formed in the housing 8.
- This control track 24 has an angled end section 34. As soon as the catch lever 22, which is connected in an articulated manner to the transmission element 20, enters this angled end section 34, this catch lever 22 pivots, as a result of which the drive device 2 is released from the carrier 21 fixed to the furniture body. Conversely, if the catch lever 22 leaves this angled end section 34, the catch 21 is caught or held between the catch lever 22 and the transfer element 20. Furthermore, the coupling element 16 of the synchronization device 6 is rotatably mounted on the housing 8 about the axis of rotation D. Integral with this coupling element 16 and the locking element 12 is formed, which forms the locking device 5 for the first ejection device 4 together with the arranged on the control lever 23 locking element 11.
- the heart cam-shaped slide track 13 formed in the housing 8 which has the clamping section S, the push-through section DR, the locking section V, the overpressure section Ü and the ejection section A.
- the locking portion V is additionally formed by the locking element 12.
- Fig. 3 are essential parts of the assembly 1 shown in assembled condition.
- the ejection force memory 10 are stretched and the locking element 11 is located in the locking portion V, whereby the first ejection device 4 is in the locking position VS. Since the Driver 21 is caught by the catch lever 22, the movable furniture part 3, not shown, is in the closed position SS.
- FIG. 4 An example of components of a - not according to the invention - synchronization device 6 is in Fig. 4 shown.
- the racks 27 and the gear 28 are movably mounted on the base plate 26.
- Fig. 5 are the individual components of the assembly 1 in not yet fully assembled state visible, since the connection via the synchronization rods 17 is not yet established. But this is in Fig. 6 shown, after which the synchronization rods 17 are each pivotally connected on the one hand with the coupling elements 16a and 16b and on the other hand with the racks 27.

- Fig. 8 shows a plan view of the arrangement 1 with the first drive device 2, the second drive device 7 and the synchronization device 6.
- the locking element 11 in the locking portion V of the heart-shaped slide track 13 is located.
- the locking element 11 bears against the locking surface 14 of the locking element 12.
- This locking surface 14 is tangential to Direction of rotation of the rotation axis D aligned.
- the ejection force accumulator 10 of the first ejection device 4 can relax.
- the housing 8 together with the movable furniture part 3 attached thereto is ejected relative to the driver 21 in the opening direction OR (see FIG Fig. 10 ), whereby the locking element 11 also enters the ejection section A of the heart-shaped cam track 13.
- the first ejection device 4 thus actually abuts the furniture body 19, in particular the driver 21. Up to this point, no movement has been transmitted to the synchronization device 6.
- the locking element 11 is but according Fig. 10 already at the synchronization surface 15 of the locking element 12. This synchronization surface 15 is aligned radially with respect to the axes of rotation D of the coupling elements 16a and 16b.
- the closing operation of the movable furniture part 3 is from Fig. 15 shown.
- the driver 21 is trapped again and via the transmission element 20, the control lever 23 and with this the locking element 11 is moved in the clamping section S, whereby the ejection force memory 10 are manually clamped when closing.
- both latching elements 11 also move in accordance with FIG Fig. 16 in abutment with the reset levers 29 of the coupling elements 16a and 16b.
- the coupling elements 16a and 16b are each rotated about the axis of rotation D, so that also according to Fig. 17 the locking elements 12 move closer and closer towards the locking portion V.
- the reset lever 29 is no longer touching and before the locking element 11 on the locking element 11 again - remain be formed in the housing 8 small locking lugs, with the Coupling elements 16a and 16b, preferably with their locking elements 12, cooperate.
- Fig. 19 an alternative embodiment of the synchronization device 6 is shown in an exploded view. Accordingly, the rack 27 is formed directly on the coupling element 16. On the housing 8, a holder 31 is fixed, on which the synchronization rod 17 is rotatably mounted with trained at the end of gear 28. The gear 28 meshes with the rack 27, so that a rotational movement of the coupling element 16 in a rotational movement of the synchronization rod 17 - and vice versa - is transmitted.
- the remaining components of the arrangement 1 according to Fig. 19 are identical to the first embodiment.
- Fig. 20 to 23a are closed Fig. 19 fitting the most important positions of the movement of the drive devices 2 and 7 and the synchronization device 6 shown.
- the rotational movement of the synchronization rod 17 is best in Fig. 23a clarified.
- the first drive device 2 occupies a position at the beginning of the clamping portion S, while the second drive device 7 assumes a position at the end of the locking portion V.
- the two drive device 2 and 7 are in different positions. Best seen are the respective positions on the position of the respective locking element 11 in the heart-shaped cam track 13.
- the locking element 11 of the first drive device 2 at the end of the Ejection section A, which simultaneously forms the beginning of the clamping section S (see detail bottom left).
- the locking element 11 of the second drive device 7 is located at the end of the locking portion V (see detail at the bottom right), thus in the locking recess of the heart-shaped cam track 13th
- the synchronization device 6 transmits motion to the second coupling element 16b of the second drive device 7, which thereby rotates clockwise , This also causes a movement of the integrally formed with the second coupling element 16b locking element 12, whereby the locking recess opens and the locking position VS is released.
- the ejection force accumulator 10 of the second drive device 7 can relax, thereby moving the ejection slide 9 through the ejection section A.
- the second drive device 7 is located as in FIG Fig. 26 shown - in a position at the end of the ejection section A while the first drive device 2 is in a position at the beginning of the locking portion V.
- Fig. 28 Components of the synchronization device 6 are illustrated.
- the first rod part 17a inserted in the third, profile-shaped or extruded rod part 17c can be seen.
- Fig. 31 the synchronization device 6 is attached to the first drive device 2.
- the drawn section ii is in Fig. 31a seen.
- Fig. 31b shows a detail Fig. 31a , In this section, it can be seen that the first rod part 17a fits snugly and thus is firmly seated or plugged in the third rod part 17c. In the same way, the first rod part 17a is also in the second Rod part 18b inserted. The frictional engagement is achieved via the contact surface 37. At the same time, however, a free space 39 also remains in sections between the first rod part 17a and the second rod part 17b.
- Fig. 31b shows a detail Fig. 31a , In this section, it can be seen that the first rod part 17a fits snugly and thus is firmly seated or plugged in the third rod part 17c. In the same way, the first rod part 17a is also in the second Rod part 18b inserted. The frictional engagement is achieved via the contact surface 37. At the same time, however, a free
- 31b is also partially the case 8 of the first drive device 2 can be seen, which is mounted on the mounting plate 38 on a movable furniture part 3, not shown.
- the first coupling element 16a is rotatably mounted, which meshes via the rack 27 with the gear 28 of the second rod portion 17b.
- the holder 31 is attached to the housing 8 and forms a pivot bearing for the synchronization rod 17th
- Fig. 32 the section ii-ii is shown, which in Fig. 32a is shown.
- Fig. 32b shows a detail Fig. 32a , It can be seen that the front portion of the first rod portion 17a is formed in cross section quadrangular with rounded corners.
- the second rod part 17b has three bulges 42 in cross-section.
- the dash-dotted line section corresponds essentially to the section II, which in Fig. 31b is shown and also illustrates the contact surface 37 and the space 39.
- the rod parts 17a and 17b to each other on a first operating position B1. In this first operating position B1, a certain holding torque H between the rod parts 17a and 17b due to the friction in the region of the contact surfaces 37 is given.
- Fig. 33 shows a detail Fig. 33a in which the first rod part 17a and the second rod part 17b form the correction device 50 in that the first rod part 17a is rotatable relative to the second rod part 17b.
- Fig. 33b shows a detail Fig. 33a in which the first rod part 17a and the second rod part 17b form the correction device 50 in that the first rod part 17a is rotatable relative to the second rod part 17b.
- the first rod part 17a to the second rod part 17b opposite Fig. 32b twisted (illustrated by the differently oriented hatching). That is, the first rod part has the holding torque H in the region of Contact surfaces 37 overcome and relative to the second rod portion 17b (in this case rotated by about 90 °) in the second operating position B2. In this second operating position B2, the holding torque H in the area of the contact surfaces 37 is again the same as in the first operating position B1.
- the marked markings M illustrate the relative rotational movement between the first rod part 17a and the second rod part 17b.
- the extent of rotation is arbitrary, as long as a malposition is compensated thereby and in the second operating position B2 again a roughly equal holding torque H is given.
- 16 mm and 19 mm are the most common board thicknesses for wood and chipboard for furniture making in the furniture industry.
- a length adjustment of the synchronization rod 17 is usually carried out.
- the holding torque H be between the two Bar parts 17a and 17b - regardless of a depth of insertion of the first rod portion 17a in the second rod portion 17b - remains substantially the same size. This is fitting in the Figs.
- the front portion of the first rod portion 17a is disposed in the region of the tabs 40 in which the second rod portion 17b is less rigid than in the area of the recesses 42.
- the total contact area 37 between the rod portions 17a and 17b is relatively large but is given a relatively low rigidity of the tabs 40.
- the elasticity and the size of the contact surfaces 37 cooperatively provide the holding torque H.
- the first rod part 17a is inserted deeper into the second rod part 17b (suitable for a plate thickness of 19 mm).
- the size of the contact surfaces 37 is lower in this case due to the recesses 42. Due to the higher rigidity of the second rod part 17b in the region close to the gearwheel, however, the same holding torque H results overall as in the case of a smaller insertion depth.
- a constant holding torque H can be ensured at different insertion depths and with constant rigidity of the components involved alone by the same size of the contact surfaces 37. This is in a comparison between the Figs. 34b and 35b illustrated.
- Fig. 36 is the same initial position of the arrangement 1 as in Fig. 24 is given, except that in this case in the reverse manner, the second drive device 7 is in a position at the beginning of the clamping portion S, while the first drive device 2 is in a position at the end of the locking portion V.
- Fig. 37a show that the games of the individual components are adjusted to each other so that when in the locked position befindlichem locking element 12 between the coupling elements 16a and 16b and the stop 43 formed by the elastic arm 44 remains a small gap. Due to its rigidity (spring hardness), the elastic arm 44 opposes a specific force K via the stop 43 of a corresponding movement of the respective coupling element 16a or 16b.
- the second coupling element 16b of the second drive device 7 begins to rotate in the clockwise direction (see FIG Fig. 38 ). This movement is transmitted via the rack 27 and the gear 28 to the synchronization rod 17. As a result, the first coupling element 16a moves counterclockwise via the left-side gearwheel 28 and the corresponding toothed rod 28 until this first coupling element 16a bears against the stop 43.
- the correction device 50 Upon continued movement of the second coupling element 16b, the correction device 50 is actuated by rotational movement between the first rod part 17a and the second rod part 17b, since the force - in terms of the holding torque H - between the two rod parts 17a and 17b is less than the force K, the stop 43 (or the elasticity of the elastic arm 44) opposes a movement of the first coupling element 16a. In other words, the first coupling element 16a is prevented from further movement in a counterclockwise direction by the stop 43. As a result, the left-side rack 27 no longer moves and the gear 28 of the left-side second rod portion 17b can not turn either.
- the second drive device 7 has in Fig. 38 already reaches the beginning of the locking portion V, from where on the contact between the control lever 23 and the second coupling element 16b stops again.
- Fig. 38 is illustrated that the stop 43, the first Coupling element 16a, the first rod portion 17a and the second rod portion 17b (with the forces acting therebetween K and H) form the correction device 50.
- the identical components on the other side also form a correction device 50.
- Fig. 40 shows still a subsequent synchronized Entriegel- or overpressing movement, whereby in this case both locking elements 11 reach the overpressure section Ü of the heart-shaped cam track 13.
- the stop 43 can also be made unyielding.
- the stop 43 may be formed by a solid surface of the housing 8.
- the compliance of the stop 43 brings an advantage in case of incorrect operation. Namely, when the drive device 2 or 7 is stopped shortly after unlocking and at the beginning of the ejection section A, the locking element 11 can get back from the "wrong" side in the detent recess by the coupling element 16 coming from the ejection section A and the locking element adjacent latching element 11 is rotated against the force K of the elastic arm 44.
- the elastic arm 44 is attached to the coupling element 16 and abuts a - then fixed and preferably formed by the housing 8 - stop 43. It is also important here that the force K between stop 43 and coupling element 16 is greater than the holding torque H.
- a correction device 50 is also used in synchronization devices 6, as in the (non-inventive) embodiments according to the Fig. 1 to 23a are described and illustrated. It is also possible that the correction device 50 is integrated in the region of the drive device 2 and 7 instead of in the region of the synchronization device 6.

Die Erfindung betrifft eine Anordnung mit einer ersten Antriebsvorrichtung zum Bewegen eines bewegbaren Möbelteils, einer zweiten Antriebsvorrichtung zum Bewegen desselben bewegbaren Möbelteils und einer Synchronisierungsvorrichtung zum Synchronisieren der beiden Antriebsvorrichtungen, wobei von beiden Antriebsvorrichtungen verschiedene Stellungen während des Bewegens des bewegbaren Möbelteils einnehmbar sind. Zudem betrifft die Erfindung ein Möbel mit einer solchen Anordnung.The invention relates to an arrangement with a first drive device for moving a movable furniture part, a second drive device for moving the same movable furniture part and a synchronization device for synchronizing the two drive devices, wherein by two drive devices different positions during movement of the movable furniture part are receivable. In addition, the invention relates to a piece of furniture with such an arrangement.
In der Möbelbeschlägeindustrie sind schon seit vielen Jahren Antriebsvorrichtungen - sogenannte Touch-Latch-Mechanismen - zum Bewegen bzw. Ausstoßen von bewegbaren Möbelteilen (Schubladen, Möbeltüren, Klappen usw.) bekannt. Dadurch wird die Öffnungsbewegung automatisch durchgeführt und ein Benutzer muss nur auf das bewegbare Möbelteil drücken, um den Ausstoßmechanismus zu aktivieren.In the furniture fitting industry driving devices - so-called touch-latch mechanisms - for moving or ejecting movable furniture parts (drawers, furniture doors, flaps, etc.) have been known for many years. As a result, the opening movement is automatically performed and a user only has to press on the movable furniture part to activate the ejection mechanism.
Speziell bei breiten Schubladen sind oft zwei Antriebsvorrichtungen an gegenüberliegenden Seitenbereichen der Schublade bzw. des Möbelkorpus vorgesehen, um ein Drücken auf die Schublade an jeder beliebigen Stelle sicher zu detektieren. Wenn nun allerdings durch dieses Drücken auf die Schublade nur eine dieser beiden Antriebsvorrichtungen auslöst, kann es zu Problemen wie einer Schiefstellung der Schublade oder eine Verklemmung bzw. Verkeilung kommen.Especially in the case of wide drawers, two drive devices are often provided on opposite side areas of the drawer or of the furniture carcass in order to reliably detect a pressing on the drawer at any desired location. However, if only one of these two drive devices triggers by pressing this on the drawer, problems such as a misalignment of the drawer or a jamming or wedging can occur.
Um diese Probleme zu lösen, sind aus dem Stand der Technik bereits diverse Methoden mit Synchronisierungsvorrichtungen zum Synchronisieren der beiden Antriebsvorrichtungen bekannt. Dadurch werden Bewegungen der beiden voneinander beabstandeten Antriebsvorrichtungen gleichgeschaltet, mit anderen Worten eben synchronisiert. Dies soll einen beidseitig gleichartigen Bewegungsablauf garantieren.In order to solve these problems, various methods with synchronization devices for synchronizing the two drive devices are already known from the prior art. As a result, movements of the two spaced-apart drive devices are switched, in other words just synchronized. This should guarantee a similar movement on both sides.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine gegenüber dem Stand der Technik verbesserte Anordnung zu schaffen. Insbesondere soll die Funktionssicherheit verbessert werden.The object of the present invention is therefore to provide a comparison with the prior art improved arrangement. In particular, the reliability should be improved.
Dies wird durch eine Anordnung mit den Merkmalen von Anspruch 1 erreicht. Demnach ist erfindungsgemäß eine Korrektureinrichtung vorgesehen, mit welcher die beiden Antriebsvorrichtungen in dieselbe Stellung gebracht werden. Mit anderen Worten wird durch die Korrektureinrichtung garantiert, dass sich beide Antriebsvorrichtungen in derselben Stellung im Bewegungsablauf der Antriebsvorrichtung befinden bzw. wieder in dieselbe Stellung gelangen.This is achieved by an arrangement having the features of
Verschiedene Stellungen der Antriebsvorrichtung sind erfindungsgemäß die Stellung in einem Spannabschnitt, die Stellung in einem Verriegelungsabschnitt, die Stellung in einem Überdrückabschnitt und die Stellung in einem Ausstoßabschnitt. Als Beispiel sei angeführt, dass sich eine der Antriebsvorrichtungen in einer Stellung zu Beginn des Spannabschnitts verbindet, während sich die andere Antriebsvorrichtung - z. B. aufgrund einer Fehlbedienung - in einer Stellung am Ende des Verriegelungsabschnitts befindet. Wenn nun eine aktive Schließbewegung des bewegbaren Möbelteils erfolgt, würde dann eine Fehlauslösung der zweitgenannten Antriebsvorrichtung erfolgen, obwohl die erstgenannte Antriebsvorrichtung noch gar nicht in eine Stellung am Ende des Verriegelungsabschnitts gelangt ist. Dies wird durch eine Korrektureinrichtung verhindert, welche die beiden Antriebsvorrichtungen - beispielsweise bevor die zweitgenannte Antriebsvorrichtung ausgelöst wird - in dieselbe Stellung bringt.Various positions of the drive device according to the invention, the position in a clamping portion, the position in a locking portion, the position in a Überdrückabschnitt and the position in a discharge section. As an example, it should be noted that one of the drive devices connects in a position at the beginning of the clamping section, while the other drive device -. B. due to incorrect operation - in a position at the end of the locking portion. Now, if an active closing movement of the movable furniture part, then a false triggering of the second-mentioned drive device would take place, although the former drive device has not yet reached a position at the end of the locking portion. This is prevented by a correction device, which brings the two drive devices - for example, before the second-mentioned drive device is triggered - in the same position.
Prinzipiell kann die Korrektureinrichtung so ausgebildet sein, dass sie eine Fehlstellung mithilfe einer entsprechenden elektronischen Detektiervorrichtung detektiert und aufgrund eines entsprechenden Signals eine Korrekturbewegung einer der Antriebsvorrichtungen auslöst. Dies kann unabhängig von der jeweiligen Position des bewegbaren Möbelteils erfolgen. Das heißt, die Korrektureinrichtung erkennt automatisch, ob eine Fehlstellung innerhalb der Anordnung gegeben ist und löst eine entsprechende Korrekturbewegung aus. Bevorzugt ist allerdings vorgesehen, dass während des Bewegens des bewegbaren Möbelteil durch die Korrektureinrichtung die beiden Antriebsvorrichtungen in dieselbe Stellung bringbar sind. Besonders bevorzugt erfolgt die Auslösung der Korrektureinrichtung durch die Bewegung des bewegbaren Möbelteils.In principle, the correction device can be designed such that it detects a misalignment by means of a corresponding electronic detection device and triggers a correction movement of one of the drive devices on the basis of a corresponding signal. This can be done independently of the respective position of the movable furniture part. That is, the correction device automatically detects whether a malposition is given within the arrangement and triggers a corresponding correction movement. Preferably, however, it is provided that during the movement of the movable furniture part by the correction device, the two drive devices can be brought into the same position. Particularly preferably, the triggering of the correction device takes place by the movement of the movable furniture part.
An sich ist es beliebig, in welche selbe Stellung die Antriebsvorrichtungen durch die Korrektureinrichtung gebracht werden. Bevorzugt ist vorgesehen, dass die Antriebsvorrichtungen durch die Korrektureinrichtung in die Verriegelungsstellung am Ende des Verriegelungsabschnitts bringbar sind.In itself, it is arbitrary, in which same position the drive devices are brought by the correction device. It is preferably provided that the drive devices can be brought by the correction device in the locking position at the end of the locking portion.
Die Korrektureinrichtung kann prinzipiell Teil der Antriebsvorrichtungen sein. Beispielsweise könnte eine Positionsüberwachung durch einen Positionssensor erfolgen. Auf Basis eines entsprechenden Signals wird dann die Bewegung einer der Antriebsvorrichtung gehemmt, bis dann die zweite Antriebsvorrichtung dieselbe Stellung erreicht. Bevorzugt ist allerdings eine rein mechanische Korrektureinrichtung vorgesehen.The correction device can in principle be part of the drive devices. For example, position monitoring could be performed by a position sensor. Based on a corresponding signal, the movement of one of the drive devices is then inhibited until the second drive device reaches the same position. Preferably, however, a purely mechanical correction device is provided.
Gemäß einem besonders bevorzugten Ausführungsbeispiel ist vorgesehen, dass die Korrektureinrichtung Bestandteil der Synchronisierungsvorrichtung ist. Eine funktionell einfache Ausführungsvariante sieht dabei vor, dass die Synchronisierungsvorrichtung eine Synchronisierungsstange mit einem ersten Stangenteil und einem zweiten, zum ersten Stangenteil drehbaren Stangenteil aufweist, wobei die beiden Stangenteile die Korrektureinrichtung mitbilden. Über die Drehbarkeit der Stangenteile zueinander wird somit die Fehlstellung der Antriebsvorrichtungen korrigiert.According to a particularly preferred embodiment, it is provided that the correction device is part of the synchronization device. A functionally simple embodiment provides that the synchronization device has a synchronization rod with a first rod part and a second rod part which can be rotated relative to the first rod part, wherein the two rod parts also form the correction device. About the rotation of the rod parts to each other thus the malposition of the drive devices is corrected.
Im Speziellen kann dies dadurch erfolgen, dass die beiden Stangenteile zueinander eine erste Betriebsstellung aufweisen, in welcher ein bestimmtes Haltedrehmoment zwischen den beiden Stangenteilen gegeben ist und die beiden Stangenteile zueinander eine zweite, zur ersten Betriebsstellung verdrehte Betriebsstellung aufweisen. Für eine gleichbleibende Funktionalität ist dabei besonders bevorzugt vorgesehen, dass in der zweiten Betriebsstellung das Haltedrehmoment zwischen den beiden Stangenteilen im Wesentlichen gleich groß ist wie das Haltedrehmoment in der ersten Betriebsstellung. Somit kann auch bei einer später nochmals folgenden Fehlstellung wiederum die Korrektureinrichtung auf gleiche Art und Weise wirksam werden.In particular, this can take place in that the two rod parts to each other have a first operating position, in which a certain holding torque between the two rod parts is given and the two rod parts to each other have a second, rotated to the first operating position operating position. For a consistent functionality is particularly preferably provided that in the second operating position, the holding torque between the two rod parts is substantially equal to the holding torque in the first operating position. Thus, even with a subsequent malposition again again the correction device can be effective in the same way.
Es ist möglich, dass die Synchronisierungsvorrichtung direkt mit einem Teil (z. B. dem Ausstoßschlitten) der jeweiligen Antriebsvorrichtung in Verbindung steht. Bei einer bevorzugten Ausführungsvariante ist aber vorgesehen, dass die Synchronisierungsvorrichtung ein erstes Kuppelelement zum Verbinden der Synchronisierungsvorrichtung mit der ersten Antriebsvorrichtung und ein zweites Kuppelelement zum Verbinden der Synchronisierungsvorrichtung mit der zweiten Antriebsvorrichtung aufweist, wobei die Kuppelelemente über die Synchronisierungsstange bewegungsübertragend verbunden sind. Diese Bewegungsübertragung erfolgt dabei bevorzugt dadurch, dass die Kuppelelemente und die Synchronisierungsstange jeweils über eine am jeweiligen Kuppelelement ausgebildete Zahnstange und über ein die Synchronisierungsstange mitbildendes Zahnrad - wobei Zahnstange und Zahnrad miteinander kämmen - verbunden sind.It is possible that the synchronizing device is directly connected to a part (eg, the ejecting carriage) of the respective driving device. In a preferred embodiment, however, it is provided that the synchronization device has a first coupling element for connecting the synchronization device to the first drive device and a second coupling element for connecting the synchronization device to the second drive device, wherein the coupling elements are connected in a transfer-transmitting manner via the synchronization rod. This movement is preferably carried out in that the coupling elements and the synchronization rod each have a formed on the respective coupling element rack and a the Synchronization rod mitbildendes gear - wherein rack and gear mesh with each other - are connected.
Um die Stellung der Antriebsvorrichtung bzw. von Teilen der Antriebsvorrichtung zu erkennen, sieht eine bevorzugte mechanische Variante vor, dass die Kuppelelemente jeweils durch einen, vorzugsweise nachgiebigen, Anschlag begrenzt bewegbar sind. Der Anschlag kann dabei Teil eines Gehäuses sein. Die Kuppelelemente wiederum sind bevorzugt an diesem Gehäuse bewegbar, insbesondere drehbar, gelagert.In order to detect the position of the drive device or of parts of the drive device, a preferred mechanical variant provides that the coupling elements are each limitedly movable by a preferably resilient stop. The stop can be part of a housing. The coupling elements in turn are preferably movable on this housing, in particular rotatable, mounted.
Für die Fehlstellungskorrektur ist gemäß einem bevorzugten Ausführungsbeispiel dann vorgesehen, dass bei am Anschlag anliegendem ersten Kuppelelement und gleichzeitiger Bewegung des zweiten Kuppelelements die Stangenteile der Synchronisierungsstange eine Bewegungsübertragung vom zweiten Kuppelelement auf das erste Kuppelelement verhindern, indem sich die Stangenteile zueinander verdrehen. Somit kann sich das erste Kuppelelement nicht bewegen und ein ungewünschtes weiterbewegen der dazugehörigen Antriebsvorrichtung in eine weitere Stellung wird unterbunden. Im Speziellen wird das Verdrehen und somit die Korrektur durch die Korrektureinrichtung dadurch ausgelöst, dass eine Drehbewegung zwischen erstem und zweitem Stangenteil erfolgt, wenn die Kraft - in Form des Haltedrehmoments - zwischen den beiden Stangenteilen kleiner ist als die Kraft, die der Anschlag einer Bewegung des Kuppelelements entgegensetzt. Dies gilt insbesondere dann, wenn der Anschlag nachgiebig, zum Beispiel als Blattfeder bzw. als elastischer Arm, ausgebildet ist. Besonders bevorzugt ist daher vorgesehen, dass die beiden Kuppelelemente, die Anschläge der Kuppelelemente und die zueinander drehbaren Stangenteile die Korrektureinrichtung bilden.For the correction of malpositioning is then provided according to a preferred embodiment, that in stop applied to the first coupling element and simultaneous movement of the second coupling element, the rod parts of the synchronization rod prevent movement of the second coupling element to the first coupling element by rotating the rod parts to each other. Thus, the first coupling element can not move and unwanted moving further of the associated drive device in a further position is inhibited. In particular, the rotation and thus the correction by the correction device is triggered by a rotational movement between the first and second rod part occurs when the force - in the form of holding torque - between the two rod parts is smaller than the force that stops the movement of the Opposite coupling element. This is especially true when the stop is compliant, for example, as a leaf spring or as an elastic arm is formed. Particular preference is therefore provided that the two coupling elements, the stops of the coupling elements and the mutually rotatable rod parts form the correction device.
Um eine möglichst gleichbleibende Funktionalität der Korrektureinrichtung zu gewährleisten, ist bevorzugt vorgesehen, dass das erste Stangenteil in das zweite Stangenteil einsteckbar ist, wobei das Haltedrehmoment zwischen den Stangenteilen - unabhängig von einer Einstecktiefe des ersten Stangenteils in das zweite Stangenteil - im Wesentlichen gleich groß bleibt.In order to ensure as constant as possible functionality of the correction device, it is preferably provided that the first rod part can be inserted into the second rod part, wherein the holding torque between the Bar parts - regardless of a depth of insertion of the first rod part in the second rod part - remains substantially the same size.
Für die Ausbildung der Antriebsvorrichtungen ist zunächst anzuführen, dass diese nicht baugleich oder funktionsgleich ausgebildet sein müssen. Für eine einfache Massenproduktion ist aber bevorzugt vorgesehen, dass die Antriebsvorrichtungen im Wesentlichen spiegelsymmetrisch ausgebildet sind.For the design of the drive devices is first to mention that they need not be identical or functionally identical. For a simple mass production but is preferably provided that the drive devices are formed substantially mirror-symmetrical.
Im konkreten ist bevorzugt vorgesehen, dass die Antriebsvorrichtungen jeweils eine verriegelbare Ausstoßvorrichtung zum Ausstoßen des bewegbaren Möbelteils aus einer Schließstellung in eine Offenstellung und eine Verriegelungsvorrichtung zum Verriegeln der Ausstoßvorrichtung in einer Verriegelungsstellung aufweisen, wobei durch eine Überdrückbewegung des bewegbaren Möbelteils in eine hinter der Schließstellung liegende Überdrückstellung die Ausstoßvorrichtung aus der Verriegelungsstellung entriegelbar ist.In concrete it is preferably provided that the drive devices each have a lockable ejection device for ejecting the movable furniture part from a closed position to an open position and a locking device for locking the ejection device in a locking position, wherein by an over-pushing movement of the movable furniture part in a behind the closed position Überdrückstellung the ejection device can be unlocked from the locking position.
Die im Folgenden näher erläuterten bevorzugten Ausführungsbeispiele sind immer für beide Antriebsvorrichtungen zu lesen, wenngleich die konkrete Beschreibung immer nur anhand der ersten Antriebsvorrichtung und deren Komponenten erfolgt. Somit gelten sämtliche Angaben sinngemäß auch für die zweite Antriebsvorrichtung.The preferred embodiments explained in more detail below are always to be read for both drive devices, although the concrete description is always made on the basis of the first drive device and its components. Thus, all information applies mutatis mutandis to the second drive device.
Konkret kann bei einem bevorzugten Ausführungsbeispiel der vorliegenden Erfindung vorgesehen sein, dass die erste Ausstoßvorrichtung ein Gehäuse, einen am Gehäuse verfahrbaren Ausstoßschlitten, einen den Ausstoßschlitten beaufschlagenden Ausstoßkraftspeicher und einen am Ausstoßschlitten bewegbar, vorzugsweise drehbar, gelagerten Steuerhebel aufweist und die erste Verriegelungsvorrichtung ein am Steuerhebel angeordnetes Rastelement und ein Verriegelungselement aufweist, an dem das Rastelement in der Verriegelungsstellung anliegt.Concretely, in a preferred embodiment of the present invention, it is provided that the first ejection device comprises a housing, an ejection slide movable on the housing, an ejection force accumulator acting on the ejector carriage, and a control lever movably mounted on the ejection carriage, preferably rotatable, and the first locking device is a control lever Catching element and a locking element, on which rests the latching element in the locking position.
Weiters ist bevorzugt vorgesehen, dass das Rastelement bei der Überdrückbewegung von der Verriegelungsstellung in einen Überdrückabschnitt bewegbar ist und bei der Öffnungsbewegung vom Ausstoßkraftspeicher durch einen Ausstoßabschnitt bewegbar ist, wobei das Verriegelungselement durch das im Ausstoßabschnitt in Öffnungsrichtung bewegte Rastelement bewegbar ist. Das heißt, wenn sich das Rastelement nicht mehr in der Verriegelungsstellung befindet, kann das Rastelement das Verriegelungselement bewegen.Furthermore, it is preferably provided that the latching element is movable in the overpressure movement from the locking position into an overpressing section and is movable by an ejection section during the opening movement of the ejection force accumulator, wherein the locking element is movable by the latching element moved in the ejection section in the opening direction. That is, when the locking element is no longer in the locking position, the locking element can move the locking element.
Grundsätzlich kann die Verriegelung über an sich bekannte Touch-Latch-Mechanismen erfolgen. Bevorzugt ist allerdings vorgesehen, dass die erste Antriebsvorrichtung eine herzkurvenförmige Kulissenbahn für das Rastelement aufweist, mit einem im Gehäuse ausgebildeten Spannabschnitt zum Spannen des Ausstoßkraftspeichers, einem Verriegelungsabschnitt, wobei das Verriegelungselement den Verriegelungsabschnitt mitbildet, dem im Gehäuse ausgebildeten Überdrückabschnitt und dem im Gehäuse ausgebildeten Ausstoßabschnitt.Basically, the locking can be done via known touch-latch mechanisms. Preferably, however, it is provided that the first drive device has a heart-shaped cam track for the latching element, with a clamping portion formed in the housing for clamping the ejection force accumulator, a locking portion, wherein the locking element mitbildet the locking portion formed in the housing overpressure portion and formed in the housing ejection section.
Weiters ist bevorzugt vorgesehen, dass das Verriegelungselement mit der Synchronisierungsvorrichtung verbunden ist. Eine besonders einfache Anordnung mit wenigen Bauteilen ergibt sich dann, wenn das Verriegelungselement einstückig mit der Synchronisierungsvorrichtung bzw. mit zumindest einem Teil der Synchronisierungsvorrichtung ausgebildet ist. Hier kann auch vorgesehen sein, dass das Verriegelungselement am Gehäuse bewegbar, vorzugsweise drehbar, gelagert ist.Furthermore, it is preferably provided that the locking element is connected to the synchronization device. A particularly simple arrangement with few components results when the locking element is formed integrally with the synchronization device or with at least part of the synchronization device. Here can also be provided that the locking element on the housing movable, preferably rotatable, is mounted.
Die besonderen Vorteile der einfachen Bauweise ergeben sich vor allem dann, wenn das Verriegelungselement eine Verriegelungsfläche, an dem das Rastelement in der Verriegelungsstellung anliegt, und ein Synchronisierungsfläche, an dem das Rastelement bei der Bewegung durch den Ausstoßabschnitt in Öffnungsrichtung anliegt, aufweist. Dabei ist die Verriegelungsfläche im Wesentlichen tangential zur Drehrichtung des Verriegelungselements ausgerichtet und die Synchronisierungsfläche ist im Wesentlichen radial in Bezug auf die Drehachse des Verrieglungselements ausgerichtet. Das heißt, durch Kraftausübung auf die Verriegelungsfläche kann keine Drehung des Verriegelungselements - und somit keine Synchronisierung - ausgelöst werden. Nur durch die Kraftausübung auf die Synchronisierungsfläche kann die Dreh- und somit Synchronisierungsbewegung erfolgen.The particular advantages of the simple design arise especially when the locking element has a locking surface on which the latching element in the locking position, and a synchronization surface on which the latching element rests in the opening direction during movement through the ejection section. The locking surface is substantially tangential to the direction of rotation of the Aligned locking element and the synchronization surface is aligned substantially radially with respect to the axis of rotation of the Verrieglungselements. That is, by applying force to the locking surface no rotation of the locking element - and thus no synchronization - can be triggered. Only by the application of force to the synchronization surface can be done the rotation and thus synchronization movement.
Bevorzugt ist das Verriegelungselement Teil des Kuppelelements. Besonders bevorzugt ist das Verriegelungselement einstückig mit dem Kuppelelement der Synchronisierungsvorrichtung ausgebildet.Preferably, the locking element is part of the coupling element. Particularly preferably, the locking element is formed integrally with the coupling element of the synchronization device.
Schutz wird auch begehrt für ein Möbel mit einem Möbelkorpus, einem am Möbelkorpus bewegbar gelagerten Möbelteil und einer erfindungsgemäßen Anordnung.Protection is also desired for a piece of furniture with a furniture body, a furniture part movably mounted on the furniture body, and an arrangement according to the invention.

Abschließend sei noch angeführt, dass der Anschlag 43 auch unnachgiebig ausgebildet sein kann. So kann der Anschlag 43 beispielsweise durch eine feste Oberfläche des Gehäuses 8 gebildet sein. Die Nachgiebigkeit des Anschlags 43 bringt aber einen Vorteil im Falle einer Fehlbedienung. Wenn nämlich die Antriebsvorrichtung 2 bzw. 7 kurz nach dem Entriegeln und am Anfang des Ausstoßabschnitts A angehalten wird, so kann das Rastelement 11 von der "falschen" Seite wieder in die Rastmulde gelangen, indem das Kuppelelement 16 vom vom Ausstoßabschnitt A kommenden und am Verriegelungselement anliegenden Rastelement 11 gegen die Kraft K des elastischen Arms 44 gedreht wird.Finally, it should be mentioned that the

- The arrangement according to claim 1, characterized in that the two drive devices (2, 7) can be brought into the same position by the correction device (50) during the movement of the moveable furniture part (3).
- The arrangement according to claim 1 or 2, characterized in that the correction device (50) is part of the synchronizing device (6).
- The arrangement according to one of the claims 1 to 3, characterized in that the synchronizing device (6) comprises a synchronizing rod (17) with a first rod member (17a) and a second rod member (17b) which is rotatable to the first rod member (17a), wherein the two rod members (17a, 17b) also form parts of the correction device (50).
- The arrangement according to claim 4, characterized in that the two rod members (17a, 17b) have a first operating position (B1) to each other, in which a predetermined holding torque (H) is given between the two rod members (17a, 17b).
- The arrangement according to claim 5, characterized in that the two rod members (17a, 17b) have a second operating position (B2) to each other, which second operating position (B2) is rotated in comparison to the first operating position (B1), wherein in the second operating position (B2) the holding torque (H) between the two rod members (17a, 17b) is substantially as large as the holding torque (H) in the first operating position (B1).
- The arrangement according to one of the claims 1 to 6, characterized in that the synchronizing device (6) comprises a first coupling element (16a) for connecting the synchronizing device (6) with the first drive device (2) and a second coupling element (16b) for connecting the synchronizing device with the second drive device (7), wherein the coupling elements (16a, 16b) are motion-transmitting connected by means of the synchronizing rod (17).
- The arrangement according to claim 7, characterized in that the coupling elements (16a, 16b) and the synchronizing rod (17) each are motion-transmitting interconnected by a gear rack (27) formed on each coupling element (16a, 16b) and by a gearwheel (28) being part of the synchronizing rod (17).
- The arrangement according to claim 7 or 8, characterized in that the coupling elements (16a, 16b) each can be moved to a limited extent by a, preferably yielding, limit-stop (43).
- The arrangement according to claim 9, characterized in that in the case of the first coupling element (16a) abutting the limit-stop (43) and simultaneous movement of the second coupling element (16b), the rod members (17a, 17b) of the synchronizing rod (17) prevent a movement transmission from the second coupling elements (16b) to the first coupling element (16a) by way of a rotation of the rod members (17a, 17b) to teach other.
- The arrangement according to claim 9 or 10, characterized in that the limit-stop (43) is formed yieldingly, preferably on an elastic arm (44), wherein a rotary movement between the first rod member (17a) and the second rod member (17b) is carried out when the force - in form of a holding torque (H) - between the two rod members (17a, 17b) is smaller than the force (K) which the limit-stop (43) opposes to a movement of the respective couplings element (16a, 16b).
- The arrangement according to one of the claims 9 to 11, characterized in that the two coupling elements (16a, 16b), the limit-stops (43) for the coupling elements (16a, 16b) and the rod members (17a, 17b) being rotatable to each other are forming the correction device (50).
- The arrangement according to one of the claims 1 to 12, characterized in that the drive devices (2, 7) each comprise a lockable ejection device (4) for ejecting the moveable furniture part (3) from a closed position (SS) into an open position (OS) and a locking device (5) for locking the ejection device (4) in a locking position (VS), wherein the ejection device (4) can be unlocked from the locking position (VS) by an over-pressing movement of the moveable furniture part (3) into an over-pressing position (ÜS) situated behind the closed position (SS).
- An item of furniture (18) comprising a furniture carcass (19), a moveable furniture part (3) being moveable on the furniture carcass (19) and an arrangement (1) according to one of the claims 1 to 13.
