Definitions
- the invention also relates to a drawer with at least one drawer extension guide of the type to be described.
- a rail misalignment occurs, for example, when the drawer rail deviates from synchronous running relative to the displaceable central rail, as a result of which the relative position of the rails to one another is incorrect.
- a carriage error is a misalignment of the carriage which builds up via an opening and closing movement and which is determined by the difference between the two and the correct starting position.
- a carriage error can build up in particular due to slippage or due to elasticity in the roller or running system during the course of movement.
- drawer extension guides are often equipped with a retraction device and with a damper, which dampens the retraction path of the drawer over the last closing area up to the fully closed position.
- dampers reduce the closing dynamics of the drawer to such an extent that a misalignment that arises during the movement of the drawer can no longer be compensated for due to a lack of kinetic energy.
- EP 1 374 734 A1 shows a drawer pull-out guide with a compensation device for compensating for a synchronization error in the guide rails.
- a compensation lever with two lever arms is mounted on the middle rail, with a first lever arm interacting with the drawer rail and a second lever arm with the body rail at the end of the closing movement.
- the compensation device is designed as a discontinuous synchronization, but rather as a so-called pseudo-synchronization or self-healing of a deep gap that arises between the back of the drawer front panel and the front of the furniture body.
- the compensation device is designed in such a way that said depth gap is corrected to a specific value when the drawer is closed.
- the disadvantage of this is that the compensation lever interacts with the drawer rail and with the cabinet rail with each closing movement, whereby in addition to unpleasant noises the friction also increases and the drawer has to be moved into the full end position with an increased expenditure of force. Due to the friction that occurs is also the To dimension the spring force of the retraction device higher, so that the drawer can be reliably pulled into the closed end position.
- the object of the present invention is to provide a drawer extension guide of the type mentioned at the beginning while avoiding the disadvantages discussed above.
- a switching device which switches the actuating device of the compensation device out of engagement with the guide rail when the predefined relative position of the guide rails is present.
- the actuation device of the compensation device can only be actuated by moving a guide rail if the guide rails are actually incorrectly positioned. If, on the other hand, there is no misalignment, the guide rails can be moved relative to one another without being impaired by the compensation device.
- the actuating device of the compensation device has an actuating element movably mounted on a guide rail, which can be actuated to compensate for the misalignment by a stop arranged or formed on another guide rail and wherein the actuating element is disengaged from the stop when the predefined relative position is present .
- the stop for actuating the actuating element can be arranged on a front end region of a guide rail.
- the stop protrudes transversely from the guide rail and preferably protrudes downward from a guide rail in the assembled position.
- the switching device can have a movably mounted switching element which is connected in a movement-coupled manner to the actuating element, for example via at least one hinge axis.
- the switching element can have a first switching position and at least one second switching position, the actuating element being in the first switching position of the switching element - if the guide rails are incorrectly positioned relative to one another - in a first position in which the actuating element can be releasably coupled to the stop, and wherein the actuating element is in the second switching position of the switching element - when the predefined relative position of the guide rails to one another is present - in a second position in which the actuating element is disengaged from the stop.
- a blocking means can be provided which is arranged or formed on one of the guide rails and which blocks a movement of the switching element - if the guide rails are incorrectly positioned relative to one another - starting from the first switching position into the second switching position. It can be provided that the switching element in the first switching position - if the guide rails are incorrectly positioned relative to one another - rests on the locking means, the actuating device of the compensation device being actuatable by a guide rail.
- the switching element In the second switching position of the switching element - when the guide rails are in the predefined relative position to each other - the switching element can be in a free position so that the actuating device of the compensation device is out of engagement with the guide rail and consequently cannot be actuated by it.
- the compensation of the misalignment during the opening movement of the Drawer extension is done. This has the advantage that a manual force has to be exerted on the drawer during the opening movement of a guide rail and that any correction of the misalignment is practically imperceptible to a user.

- a functional unit 18 with an end stop 20 is provided which, in the closed position of the drawer extension guide 4, strikes a counter-stop 21 of the first guide rail 9 to limit an insertion movement of the third guide rail 11.
- a compensation device 22 is provided, by means of which a misalignment of the guide rails 9, 10, 11 with respect to one another that deviates from a predefined relative position can be compensated.
- compensation device 22 comprises a stop 19, which protrudes transversely downward from third guide rail 11, and an actuating device 17 arranged on second guide rail 10, which can be actuated by stop 19 if guide rails 9, 10, 11 are incorrectly positioned.
- Fig. 3a shows the pull-out drawer slide 4 in the closed position with the first, second and third guide rails 9, 10, 11 in a perspective view.
- Figure 3b shows the in Fig. 3a circled area in an enlarged view.

- Figure 3c shows a side view of the drawer extension slide 4
- Fig. 3d shows the in Figure 3c framed front area in an enlarged view.
- the actuating device 17 has a movably, preferably pivotably, mounted actuating element 17a, which can be releasably coupled to the stop 19 in the event of an incorrect position.
- the actuating element 17a can, for example, have an arcuate circumferential surface along which the stop 19 can be moved at least in sections.
- the actuating device 17 can be switched out of engagement with the third guide rail 11, preferably the stop 19, when the (correct) predefined relative position of the guide rails 9, 10, 11 is present.
- the switching device 27 has a movable switching element 27a, preferably mounted pivotably about an axis 24, which is connected in a movement-coupled manner to the actuating element 17a.
- the switching element 27a and the actuating element 17a are pivotably connected to one another via at least one moving hinge axis 25.
- an energy store 26 By means of an energy store 26, these are The actuating element 17a and the switching element 27a are prestressed relative to one another in such a way that the actuating element 17a and the switching element 27a are pushed apart by the force of the energy accumulator 26 about the hinge axis 25.
- the switching element 27a is mounted pivotably about the axis 24 and has a projection 27b which, in the closed position of the second guide rail 10, rests against a locking means 23, preferably a web, of the first guide rail 9.
- the locking means 23 prevents the switching element 27a from moving from the first switching position into the second switching position, if the guide rails 9, 10, 11 are incorrectly positioned relative to one another.
- the guide rails 9, 10, 11 assume a correct, predefined position relative to one another.
- Figure 4a shows the drawer extension guide 4 in a cross section.
- a first carriage 15 with first rolling elements 36 ( Figure 7a ) stored
- a second carriage 28 with second rolling elements 37 is displaceably arranged.
- the sequence of movements of the two carriages 15, 28 relative to one another can be controlled by a synchronization device 13.
- the synchronization device 13 comprises a toothed wheel 14 rotatably mounted on the second guide rail 10, which meshes with a first toothing 15a of the (lower) first carriage 15 and with a second toothing 28a of the (upper) second carriage 28.
- the third guide rail 11 is in a slightly open position.
- Figure 4b shows the in Figure 4a framed, front area of the drawer extension guide 4 in an enlarged view, from which the compensation device 22 emerges in more detail.
- the guide rails 9, 10, 11 are in a predefined, correct position relative to one another. If now the third guide rail 11 starting from the in Fig. 3d the closed position shown is moved in the pull-out direction 29, Thus, the switching element 27a reaches a free position 30, so that the switching element 27a together with the actuating element 17a is tilted clockwise around the axis 24 in such a way that the stop 19 arranged on the third guide rail 11 can be moved further in the direction of the open position without being hindered by the actuating device 17 is.
- the clearance 30 can either be designed as a recess in the first guide rail 9, or - as shown in the figure - be formed by a free space located in front of the first guide rail 9 in the assembled position, so that the projection 27b of the switching element 27a virtually travels into the void.
- the third guide rail 11 moves against the pull-out direction 29, it can be moved back into the closed position by the actuating device 17 without hindrance, the actuating element 17a being overridden by the stop 19, if necessary, against the force of the energy accumulator 26.
- Figure 5a shows the drawer extension slide 4 in a perspective view, the guide rails 9, 10, 11 - for example due to a slip occurring between the carriages 15, 28 and the guide rails 9, 10, 11 - assume a misalignment that deviates from the predefined relative position. This can, for example, lead to the second guide rail 10 being positioned too far back relative to the first guide rail 9, that is to say that the first and second guide rails 9, 10 are positioned over a contact point 31 ( Figure 5b ) are in contact with each other and there is therefore a misalignment to be corrected.
- Figure 5b shows the in Figure 5a circled area in an enlarged view.
- Figure 5c shows a side view of the drawer extension slide 4, while in Fig. 5d the in Figure 5c framed front area of the drawer pull-out guide 4 is shown enlarged.
- the projection 27b of the switching element 27a rests on the locking means 23 of the first guide rail 9.
- the foremost area of the web of the first guide rail 9 can run obliquely downwards towards the front, whereby the friction is reduced and the tilting behavior of the switching element 27a is improved.
- FIGs 6a-6d show a chronological sequence of the opening movement of the third guide rail 11 in the pull-out direction 29.
- the actuating element 17a of the actuating device 17 is contacted by the stop 19 of the third guide rail 11 ( Figure 6a ).
- the projection 27b of the switching element 27a rests against the locking means 23 of the first guide rail 9, the locking means 23 preventing the switching element 27a from moving into a second, deactivated switching position of the switching element 27a, so the switching element 27a cannot be tilted about the axis 24 .
- the third guide rail 11 is thus coupled to the second guide rail 10 via the stop 19 and via the actuating element 17a. Since the third guide rail 11 extends through the synchronization device 13 ( Fig. 2 ) moves at a higher, preferably approximately twice, speed than the second guide rail 10, the second guide rail 10 is briefly coupled to the higher speed of the third guide rail 11. The second guide rail 10 and the third guide rail 11 can therefore be moved at the same speed relative to the first guide rail 9 when compensating for a misalignment, the second guide rail 10 being dragged over the rolling elements 36 of the first carriage 15 ( Figures 6b, 6c ).
- the projection 27b of the switching element 27a can move out again over the front end of the first guide rail 9, so that the switching element 27a is tilted about the axis 24 and thereby the coupling between the actuating element 17a and the stop 19 of the third guide rail 11 is released becomes.
- the second guide rail 10 thus has in Fig. 6d reaches its target position relative to the first guide rail 9 again.
- Figure 7a shows the drawer extension slide 4 in an exploded view.
- the first guide rail 9 is on a furniture body 2 and the third Guide rail 11 is to be fastened to the drawer 3, the second guide rail 10 being slidably mounted between the first and third guide rails 9 and 11.
- a first carriage 15 with a plurality of rolling elements 36 spaced apart from one another in the longitudinal direction and a further carriage 38 with rolling elements 38a, separate therefrom, are slidably mounted.
- a second carriage 28 with a plurality of rolling elements 37 spaced apart from one another in the longitudinal direction is slidably mounted.
- the movements of the carriages 15, 28 with respect to one another can be controlled by a gear 14 rotatably mounted on the second guide rail 10, which meshes with the teeth 15a, 28a of the first and second carriages 15, 28.
- the bearing part 16 is to be fastened with the actuating device 17 and with the switching device 27.
- the functional unit 18 with the end stop 20 and the stop 19 is arranged on the front end region of the third guide rail 11.
- a movable driver 34 which is pretensioned by a spring device 32, the third guide rail 11 can be drawn into the closed end position towards the end of the closing movement.
- This spring-assisted pull-in movement can be braked into the closed end position by a damping device 33, preferably with a piston-cylinder unit.
- the spring device 32 and the damping device 33 are fastened to the third guide rail 11 via a holder 35.
- Figure 7b shows the actuating device 17 arranged on the bearing part 16 and the switching device 27 in an exploded view.

- the switching element 27a can be pressed against the locking means 23 by the force of the energy accumulator 26, which results in a defined switching behavior of the switching element 27a between the two switching positions.
- the actuating element 17a during the insertion movement of the third guide rail 11 against the force of the energy accumulator 26, so that the third guide rail 11 can be moved into the closed position without significant hindrance.
- the actuating device 17 can be arranged not only on the second guide rail 10, but also on the other guide rails 9, 11 and at other positions along their longitudinal direction. For example, it is possible to arrange the actuating device 17 to correct a misalignment of the third guide rail 11 relative to the second guide rail 10 on the third guide rail 11 and the stop 19 to actuate the actuating device 17 on the second guide rail 10.

Description
Die vorliegende Erfindung bezieht sich auf eine Schubladenausziehführung, umfassend:
- wenigstens zwei Führungsschienen, welche relativ zueinander verschiebbar gelagert sind,
- zumindest einen Laufwagen mit lastübertragenden Wälzkörpern, wobei der Laufwagen zwischen den wenigstens zwei Führungsschienen verfahrbar gelagert ist, wobei die Führungsschienen bei einer Bewegung des zumindest einen Laufwagens eine vordefinierte Relativstellung zueinander einnehmen, falls keine Fehlstellung der Führungsschienen zueinander vorliegt,

- at least two guide rails, which are mounted so that they can be moved relative to one another,
- at least one carriage with load-transferring rolling elements, the carriage being movably mounted between the at least two guide rails, the guide rails assuming a predefined relative position to one another when the at least one carriage is moved, if there is no misalignment of the guide rails to one another,
- a compensation device for compensating for a misalignment of the guide rails to one another that deviates from the predefined relative position, the compensation device having an actuating device which can be actuated by one of the guide rails and which compensates for the misalignment when actuated.
Im Weiteren betrifft die Erfindung eine Schublade mit wenigstens einer Schubladenausziehführung der zu beschreibenden Art.The invention also relates to a drawer with at least one drawer extension guide of the type to be described.
Als Fehlstellungen bei Schubladenausziehführungen werden sowohl Schienenfehlstellungen als auch Laufwagenfehlstellungen bezeichnet, welche zu einem Offenstehen der Schublade im normalen Gebrauch führen können. Eine Schienenfehlstellung tritt beispielsweise dann auf, wenn die Ladenschiene relativ zur verschiebbaren Mittelschiene vom synchronen Lauf abweicht, wodurch die Relativlage der Schienen zueinander nicht korrekt ist. Als Laufwagenfehler wird hingegen eine Fehlstellung des Laufwagens bezeichnet, welche sich über eine Öffnungs- und Schließbewegung aufbaut und welche durch die aufgebaute Differenz zur korrekten Ausgangslage bestimmt ist. Ein Laufwagenfehler kann sich insbesondere durch Schlupf oder aufgrund von Elastizität im Rollen- bzw. Laufsystem während des Bewegungsablaufes aufbauen. Ab einer bestimmten Anzahl von Bewegungen kann sich der Laufwagen schließlich so weit von seiner Sollposition entfernen, dass dieser auf einen Endanschlag im Schienensystem auftrifft, bevor die Schublade überhaupt die vollständige Endlage relativ zum Möbelkorpus erreicht. Schubladenausziehführungen sind zudem häufig mit einer Einzugsvorrichtung und mit einem Dämpfer ausgerüstet, welcher den Einzugsweg der Schublade über den letzten Schließbereich bis hin zur vollständigen Schließstellung dämpft. Diese Dämpfer verringern jedoch die Schließdynamik der Schublade dermaßen, dass eine während der Bewegung der Schublade entstandene Fehlstellung mangels fehlender Bewegungsenergie nicht mehr ausgeglichen werden kann. Bei jeder zusätzlichen Bewegung, bei der die Schublade nicht vollständig geöffnet wird, bleibt die Schublade aufgrund der Fehlstellung in einer Offenstellung stehen, was optisch störend wirkt und überdies auch die Gefahr von Kollisionen mit Personen oder Objekten mit sich bringt.Both rail misalignments and carriage misalignments, which can lead to the drawer standing open during normal use, are referred to as misalignments in drawer extension guides. A rail misalignment occurs, for example, when the drawer rail deviates from synchronous running relative to the displaceable central rail, as a result of which the relative position of the rails to one another is incorrect. On the other hand, a carriage error is a misalignment of the carriage which builds up via an opening and closing movement and which is determined by the difference between the two and the correct starting position. A carriage error can build up in particular due to slippage or due to elasticity in the roller or running system during the course of movement. From a certain Number of movements, the carriage can finally move so far away from its target position that it hits an end stop in the rail system before the drawer even reaches the complete end position relative to the furniture body. In addition, drawer extension guides are often equipped with a retraction device and with a damper, which dampens the retraction path of the drawer over the last closing area up to the fully closed position. However, these dampers reduce the closing dynamics of the drawer to such an extent that a misalignment that arises during the movement of the drawer can no longer be compensated for due to a lack of kinetic energy. With every additional movement in which the drawer is not fully opened, the drawer remains in an open position due to the misalignment, which is visually disruptive and also brings with it the risk of collisions with people or objects.
In der
Aufgabe der vorliegenden Erfindung ist es, eine Schubladenausziehführung der eingangs erwähnten Gattung unter Vermeidung der oben diskutierten Nachteile anzugeben.The object of the present invention is to provide a drawer extension guide of the type mentioned at the beginning while avoiding the disadvantages discussed above.
Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Unteransprüchen angegeben.This is achieved according to the invention by the features of
Gemäß der Erfindung ist also vorgesehen, dass eine Schaltvorrichtung vorgesehen ist, welche die Betätigungsvorrichtung der Kompensationsvorrichtung bei Vorliegen der vordefinierten Relativstellung der Führungsschienen zueinander außer Eingriff mit der Führungsschiene schaltet.According to the invention it is therefore provided that a switching device is provided which switches the actuating device of the compensation device out of engagement with the guide rail when the predefined relative position of the guide rails is present.
Mit anderen Worten ist die Betätigungsvorrichtung der Kompensationsvorrichtung nur dann durch eine Bewegung einer Führungsschiene betätigbar, sofern tatsächlich eine Fehlstellung der Führungsschienen vorliegt. Liegt hingegen keine Fehlstellung vor, so sind die Führungsschienen ohne Beeinträchtigung durch die Kompensationsvorrichtung relativ zueinander verfahrbar.In other words, the actuation device of the compensation device can only be actuated by moving a guide rail if the guide rails are actually incorrectly positioned. If, on the other hand, there is no misalignment, the guide rails can be moved relative to one another without being impaired by the compensation device.
Dabei kann vorgesehen sein, dass die Betätigungsvorrichtung der Kompensationsvorrichtung ein an einer Führungsschiene bewegbar gelagertes Betätigungselement aufweist, welches zur Kompensation der Fehlstellung durch einen an einer anderen Führungsschiene angeordneten oder ausgebildeten Anschlag betätigbar ist und wobei das Betätigungselement bei Vorliegen der vordefinierten Relativstellung vom Anschlag außer Eingriff steht.It can be provided that the actuating device of the compensation device has an actuating element movably mounted on a guide rail, which can be actuated to compensate for the misalignment by a stop arranged or formed on another guide rail and wherein the actuating element is disengaged from the stop when the predefined relative position is present .
Der Anschlag zur Betätigung des Betätigungselementes kann dabei an einem vorderen Endbereich einer Führungsschiene angeordnet sein. Dabei kann vorgesehen sein, dass der Anschlag von der Führungsschiene quer absteht und vorzugsweise in Montagelage von einer Führungsschiene nach unten ragt.The stop for actuating the actuating element can be arranged on a front end region of a guide rail. Here can it can be provided that the stop protrudes transversely from the guide rail and preferably protrudes downward from a guide rail in the assembled position.
Die Schaltvorrichtung kann ein bewegbar gelagertes Schaltelement aufweisen, welches mit dem Betätigungselement bewegungsgekoppelt verbunden ist, beispielsweise über wenigstens eine Gelenkachse. Das Schaltelement kann eine erste Schaltstellung und zumindest eine zweite Schaltstellung aufweisen, wobei sich das Betätigungselement in der ersten Schaltstellung des Schaltelementes - bei Vorliegen der Fehlstellung der Führungsschienen zueinander - in einer ersten Stellung befindet, in welcher das Betätigungselement mit dem Anschlag lösbar koppelbar ist, und wobei sich das Betätigungselement in der zweiten Schaltstellung des Schaltelementes - bei Vorliegen der vordefinierten Relativstellung der Führungsschienen zueinander - in einer zweiten Stellung befindet, in welcher das Betätigungselement vom Anschlag außer Eingriff steht.The switching device can have a movably mounted switching element which is connected in a movement-coupled manner to the actuating element, for example via at least one hinge axis. The switching element can have a first switching position and at least one second switching position, the actuating element being in the first switching position of the switching element - if the guide rails are incorrectly positioned relative to one another - in a first position in which the actuating element can be releasably coupled to the stop, and wherein the actuating element is in the second switching position of the switching element - when the predefined relative position of the guide rails to one another is present - in a second position in which the actuating element is disengaged from the stop.
Zur Steuerung einer Bewegung des Schaltelementes kann ein Sperrmittel vorgesehen werden, welches an einer der Führungsschienen angeordnet oder ausgebildet ist und welches eine Bewegung des Schaltelementes - bei Vorliegen der Fehlstellung der Führungsschienen zueinander - ausgehend von der ersten Schaltstellung in die zweite Schaltstellung sperrt. Dabei kann vorgesehen sein, dass das Schaltelement in der ersten Schaltstellung - bei Vorliegen der Fehlstellung der Führungsschienen zueinander - am Sperrmittel anliegt, wobei die Betätigungsvorrichtung der Kompensationsvorrichtung durch eine Führungsschiene betätigbar ist. In der zweiten Schaltstellung des Schaltelementes - bei Vorliegen der vordefinierten Relativstellung der Führungsschienen zueinander - kann sich das Schaltelement in einer Freistellung befinden, sodass die Betätigungsvorrichtung der Kompensationsvorrichtung außer Eingriff mit der Führungsschiene steht und folglich durch diese nicht betätigbar ist.To control a movement of the switching element, a blocking means can be provided which is arranged or formed on one of the guide rails and which blocks a movement of the switching element - if the guide rails are incorrectly positioned relative to one another - starting from the first switching position into the second switching position. It can be provided that the switching element in the first switching position - if the guide rails are incorrectly positioned relative to one another - rests on the locking means, the actuating device of the compensation device being actuatable by a guide rail. In the second switching position of the switching element - when the guide rails are in the predefined relative position to each other - the switching element can be in a free position so that the actuating device of the compensation device is out of engagement with the guide rail and consequently cannot be actuated by it.
Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass die Kompensation der Fehlstellung bei der Öffnungsbewegung der Schubladenausziehführung erfolgt. Dies hat den Vorteil, dass bei der Öffnungsbewegung einer Führungsschiene ohnehin eine manuelle Kraft auf die Schublade ausgeübt werden muss ist und dass sich eine allfällige Korrektur der Fehlstellung für einen Benutzer praktisch nicht bemerkbar macht.According to one embodiment it can be provided that the compensation of the misalignment during the opening movement of the Drawer extension is done. This has the advantage that a manual force has to be exerted on the drawer during the opening movement of a guide rail and that any correction of the misalignment is practically imperceptible to a user.

Überdies ist eine Kompensationsvorrichtung 22 vorgesehen, durch welche eine von einer vordefinierten Relativstellung abweichende Fehlstellung der Führungsschienen 9, 10, 11 zueinander kompensierbar ist. Die Kompensationsvorrichtung 22 umfasst im gezeigten Ausführungsbeispiel einen Anschlag 19, welcher von der dritten Führungsschiene 11 quer nach unten absteht sowie eine an der zweiten Führungsschiene 10 angeordnete Betätigungsvorrichtung 17, welche bei einer Fehlstellung der Führungsschienen 9, 10, 11 durch den Anschlag 19 betätigbar ist.In addition, a
Die Betätigungsvorrichtung 17 kann, anders als in den Figuren gezeigt, nicht nur an der zweiten Führungsschiene 10, sondern auch an den anderen Führungsschienen 9, 11 und an anderen Positionen entlang deren Längsrichtung angeordnet werden. So ist es beispielsweise möglich, die Betätigungsvorrichtung 17 zur Korrektur einer Fehlstellung der dritten Führungsschiene 11 relativ zur zweiten Führungsschiene 10 an der dritten Führungsschiene 11 und den Anschlag 19 zur Betätigung der Betätigungsvorrichtung 17 an der zweiten Führungsschiene 10 anzuordnen.In contrast to the figures shown, the
