Definitions
- the present invention relates to a Rollenauszieh arrangement for pulling out a furniture part of a furniture body in a withdrawal direction and for inserting the furniture part in the furniture body in a direction of insertion with at least one guide rail and at least one guided in this role and a Diseinzugsvorraum with a spring-loaded, tiltable and slidably mounted tilting slide for retracting the furniture part in the insertion direction.
- Rollenauszieh exiten this type are known per se.
- the self-closing device is used to automatically pull the furniture part completely in the direction of insertion into the furniture body, ie in the closed position, after the furniture part has been inserted a certain distance in the insertion direction, for example by hand in the furniture body.
- various solutions are known with tilting valves. It is also known to provide such intake mechanisms with insertion dampers to dampen the retraction movement of the Rollenauszieh Entry in the last section.
- Such a damped pull-in mechanism or self-closing device, in which the tilting slide cooperates with a slide-in damper is for example from EP 1 532 892 A1 known.
- the tilting slide said self-closing devices cooperate with a driver, which is arranged on the extendable furniture part.
- a driver which is arranged on the extendable furniture part.
- Similar Diseinzugsvoriquesen, but without damper go for example from the AT 401 334 B in which also a displaceable against the force of a spring tilt slide is available.
- the tilting slide is arranged tiltable about a tilting axis on a slide which can be moved in a straight line in the pull-out direction of the drawer against the force of the spring.
- known Adeinzugsvorraum is also a tilt slide available, which is displaceable along a guideway against the force of a spring.
- the guideway has on a straight portion a bent portion which causes the pivoting of the tilting slide about an imaginary tilting axis in its tilted end position.
- Object of the present invention is to provide a generic Rollenauszieh arrangement in which with as few parts and as few processing steps high reliability can be guaranteed.
- the tilting slide has a gripper, which for feeding the furniture part in the insertion direction on the roller attacks.
- the tilting slide engages itself via its associated gripper on a roll of Rollenauszieh arrangement. It can therefore be applied to additional and common in the prior art driver such. Hook or similarly shaped parts on which the tilting slide attacks, be waived. This saves on the one hand processing steps, on the other hand also parts.
- a Rollenauszieh arrangement can also be built very compact. A particular advantage, however, lies in the fact that, despite sufficient movement play, a high level of operational reliability can be ensured.
- roller extension guide is rotatably mounted, preferably rotatably mounted, on a second rail of the roller extension guide, preferably by means of a roller rotation axis fastened to the second rail. It is thus preferred that at least one roller is rotatably mounted on a rail.
- additional rollers may be rotatably mounted or fastened on the rails of the roller extension guide, preferably by means of their roller pivot axes. The role or roles preferably have a supporting function.
- roller extension guides according to the invention can also be designed with conventional carriages in which balls and / or rollers are rotatably mounted.
- the guide rail may be, for example, the rail, which is fixed to the furniture body.
- the second rail is then conveniently the rail of Rollenauszieh Entry, which is attached to the relative to the furniture body slidably mounted furniture part.
- the guide rail and the second rail are then conveniently displaceably mounted by means of said rollers and / or carriages.
- On two opposite sides of the furniture part can ever be arranged such a Rollenauszieh arrangement.
- the Rollenauszieh Entry may each have at least one further rail, for example, a middle rail, which is relatively movable or displaceable both to the guide rail, and to the second rail.
- Roller extension guides according to the invention can thus also be designed as differential slide guides known per se.
- a Rollenauszieh Inventory, in which on each side of the furniture part three rails slidably to each other, are stored in each other, is in itself eg in the EP 1 532 892 A1 shown.
- the tilting slide has a gripper which engages for retraction of the furniture part in the direction of insertion on the roller.
- the retraction of the furniture part includes two sections. First, the gripper of the tilting slide must engage the roller. This is referred to below as the contacting process. This is followed by the actual pulling-in process in which the self-closing device pulls over the tilting slide on the roller or the second rail connected thereto in the insertion direction.
- the above-mentioned retraction of the furniture part refers both to the attacking process as well as the Einziehvorgang.
- both the contacting operation and the pulling-in operation are achieved by the engagement of the gripper of the gripper Tilting slide on the roller takes place.
- a method for operating such, according to the invention Rollenauszieh Installationen can then provide that the tilting slide is tilted by hitting the roller on the gripper from a first tilted position to the second tilted position, which is brought by this tilting of the gripper and the roller engaged with each other and thereafter the roller is pulled on the gripper of the tilting slide hanging from the tilting slide in the insertion direction.
- the second rail is thus retracted by the gripper acts directly on the roller and thus pulled on the roller.
- the gripping of the gripper on the roller takes place only during the contacting process. It can therefore also be provided that the retraction of the furniture part in the insertion direction only partially, ie z. B. only the contacting process, takes place by the attack of the gripper on the roller.
- the insertion process can be provided in these variants of the invention, other means with which the tilt slide on the second rail.
- a preferred group of embodiments of the invention provides that on the tilt slide a first coupling part is arranged and on the second rail, a second coupling part is arranged, wherein the coupling parts are dissolved in a first tilted position of the tilting slide from each other and in a second tilted position of Tilting slide are engaged with each other, wherein in the first tilt position, the second rail and the tilt slide in the extension direction and / or in the insertion direction relative to each other are movable and in the second tilt position, the second rail and the tilt slide with respect to a movement in the pull-out direction and / or in the insertion direction with each other are positively coupled.
- Forced coupling means in this context in particular, that rail and tilting slide can only be moved together in the pull-out direction and / or in the insertion direction in the second tilted position.
- a method for operating such a Rollenauszieh arrangement may then provide that the toggle is tilted by the occurrence of the role on the gripper from the first tilted position to the second tilted position, this tilting the coupling parts are engaged with each other and then the second rail over the coupling parts is pulled on the tilting slide hanging from the tilting slide in the insertion direction.
- the tilting of the tilting slide takes place during the contacting process by engaging the gripper of the tilting slide on the roller, but during the subsequent retraction process the tilting slide engages directly on the second rail via the coupling parts engaged with one another, so that the Weight of the second rail and the associated piece of furniture to be recovered no longer acts on the roller via the gripper.
- the frictional forces between the roller and gripper can be minimized or eliminated during the pulling-in process.
- the gripper of the tilting slide can attack at different points on the roller.
- the gripper of the tilting slide engages the roller rotation axis of the roller.
- the roller has a running surface, with which it runs in the guide rail, and engages the gripper of the tilting slide on the running surface of the roller. This allows a particularly reliable roller extension guide which can still be equipped with a lot of movement play. In addition, this is also a very space-saving variant.
- the gripper one, preferably at least partially, e.g.
- the gripper limiting gripper surface has arcuately curved and / or a recess in the gripper limiting gripper surface, with which he attacks, preferably the tread, the roller.
- the length of the gripper surface measured in the withdrawal direction, is at least one-eighth, preferably at least a quarter, of the total circumference of the running surface of the roller.
- the part of the gripper surface is to be considered, which can actually embrace the role.
- the length specification refers to a measurement along the curved gripper surface in the pull-out direction and not to the pull-out, imaginary chord between the end points of the gripper surface.
- the gripper may have a recess for receiving the roller, which is bounded by two preferably curved gripper legs.
- particularly preferred embodiments of the invention provide that at least one of the gripper legs is formed elastically deformable and has an oblique to the insertion direction starting bevel, wherein the role is pushed by tarnishing the roller against the chamfering surface and by elastic deformation of the gripper leg on the gripper arm over into the recess of the gripper.
- a particularly preferred embodiment provides that on the tilting slide, preferably in one piece, a damper part of a damper having at least two mutually movable damper parts, preferably rotational damper or linear damper, is arranged. This also minimizes the number of parts and space requirements.
- the Rollenauszieh installation the first embodiment of two different sides is shown. It has a guide rail 3 and a second rail 8 mounted displaceably therein. These two rails 3 and 8 can be pulled apart telescopically in the withdrawal direction 1 and pushed into each other in the opposite direction of insertion 2.

- FIGS. 14 to 24 show a second embodiment according to the invention a Rollenauszieh Entry. This is similar or similar in many parts to the first embodiment. However, differences exist in the type and connection of the damper 24 used and in the specific embodiment of the invention acting on the roller 4 tilting slide 6. The following description focuses on the explanation of the differences from the first embodiment. The details not explained in detail may be carried out as in the first embodiment.
- the FIGS. 14 and 15 First of all, views again point to this embodiment of the Rollenauszieh Entry from two sides.
- the second rail 8 can be made completely as in the first embodiment and is not shown again here. With respect to the rail 8 is thus on the 3 and 4 directed.
- the guide or cabinet rail 3 is without second rail 8 in the FIGS. 16 and 17 shown.
- Fig. 19 again shows the section according to Fig. 18 along the section line CC.
- Fig. 20 shows a side view of this embodiment in the position according to Fig. 19.
- Fig. 22 shows the section along the line DD in Fig. 21 , Here, the roller 4 and the second rail 8 are completely retracted.
- Fig. 23 shows the corresponding side view.
- a first difference from the first exemplary embodiment consists in that, instead of the rotary damper shown there, a linear damper 24 known per se is used. This has two relatively movable damper parts 22 and 23. 22 designates in the embodiment shown, the per se known piston rod 22 with the piston arranged thereon.
- FIGS. 19 and 20 again show the position of the tilt slide, in which he receives the roller 4 in its recess 11.

- Fig. 33 the longitudinal section along the section line EE.
- FIGS. 34 to 36 show in otherwise to the FIGS. 31 to 33 analog representations, the situation in which the roller 4 at the beginning of the contacting during insertion in the direction of insertion 2 on the gripper 7 meets or even the situation in which when pulling in the pull-out 1 of the tilt slide 6 is already back in the first tilted or ready position is located, so the role is not 4 is held more and the second rail 8 can be further pulled in the direction of withdrawal 1.
- a first essential difference to the first two embodiments is in the third embodiment is that the housing 25 'of this embodiment has no U-shaped recess 26, but, preferably completely, seen in an operating position of the Rollenauszieh Installation, above the guide rail 3 is arranged. Of course, it can just as well, preferably completely, be arranged below the guide rail 3. Both variants have the advantage that overall the overall length of the roller extension guide is shortened, since the housing 25 'no longer projects beyond the guide rail 3 at the rear end.
- the spring 31, which provides the force for pulling in the roller 4 or the second rail 8, is no longer deflected.
- the spring 31 has an exclusively linear extension.
- the spring 31 is arranged, preferably exclusively, above the guide rail 3. Also, it is not in the insertion direction 2 on the guide rail 3 via. But just as well, the spring 31 may also, preferably exclusively, be arranged below the guide rail 3.
- the housing 25 'of the Dieinzugsvorraum 5 of this embodiment is constructed in two parts. It has a fixed to the guide rail 3 immovably fixed housing part 38. This in turn has in this embodiment, a housing rail 39 on which a connecting rod designed as a connecting element 35 is mounted relative to the fixed housing part 38, preferably parallel to the withdrawal direction 1 or insertion direction 2, slidably. As shown in particular in the sectional views. Fig. 33 and 36 can be seen, the tilting slide 6 of this embodiment is arranged on the pivot joint 34 on the connecting rod designed as a connecting body 35.
- a damper part of the damper 24 designed here as a linear damper 24 is fixed to the connecting body or the push rod 35 in the third exemplary embodiment.
- this is the damper part 23, which forms the cylinder of the damper 24.
- the piston is displaceably mounted, which is fixed to the other damper part 22 designed as a piston rod.
- the damping operation of the damper 24 takes place by sliding the damper part 23 on the piston rod or the damper part 22, at least for a part of the intake operation in the insertion direction 2.
- the damper can also be designed so that it achieves a movement-damping effect in the withdrawal direction.
- the tilting slide 6 is, as in the first embodiments, guided by means of the first guide pin 17 and the pivot pin 18 in a guide track 20, which has the angled portion 21 at its front end seen in the insertion direction 2.
- the guidance and the tilting of the tilting slide 6 by means of the guideway 2 and its angled portion 21 takes place as in the two embodiments set forth first.
- the tilting movement takes place in the pivot joint 34.
- Fig. 36 is the tilting slide 6 with its gripper 7 in the ready position or in the first tilted position.
- the roll can accumulate by corresponding insertion of the second rail 8 in the insertion direction 2 on the gripper surface 12 of the gripper 7 of the tilting slide 6.
- the gripper 7 of the tilting slide 6 engages the roller 4, in the exemplary embodiment shown, specifically at its running surface 10.
- Fig. 36 is tilted about the axis of rotation of the pivot joint 34 in its second tilted position.
- the second tilt position is z. In Fig. 33 to see.
- the first coupling part 36 is a corresponding recess in the front gripper limb 15 of the gripper 7 as viewed in the insertion direction 2.
- the second coupling part 37 is formed in the embodiment shown by a pin arranged on the second rail 8.
- the coupling parts 36 and 37 may also, unlike the exemplary embodiment shown, be arranged the other way around on tilting slide 6 and second rail 8.
- FIGS. 31 to 33 show the fully retracted position in which the roller 4 abuts the end stop 33 of the guide rail 3.
- the two coupling parts 36 and 37 are also in this position still engaged with each other. If now pulled on the second rail 8 and attached to a movable furniture part in the withdrawal direction 1, the tilting slide 6, via the coupling parts 36 and 37 directly on the second rail 8 hanging, moved in the withdrawal direction 1, so that after a through the Length of the straight portion of the guide track 20 predetermined path of the first guide pin 17 in the arranged on the fixed housing part 38 guide track 20 enters the angled section 21. By continuing the first guide pin 17 in the angled portion 21 then takes place a tilting movement of the tilting slide 6 back into the first tilted position or in the ready position gem.

Mit anderen Worten ist somit vorgesehen, dass der Kippschieber über den ihm zugeordneten Greifer an einer Rolle der Rollenausziehführung selbst angreift. Es kann daher auf zusätzliche und beim Stand der Technik übliche Mitnehmer wie z.B. Haken oder ähnlich ausgeformte Teile, an denen der Kippschieber angreift, verzichtet werden. Dies spart zum einen Bearbeitungsschritte, zum anderen aber auch Teile. Darüber hinaus kann eine solche Rollenausziehführung auch sehr kompakt gebaut werden. Ein besonderer Vorteil liegt aber darin, dass trotz eines ausreichenden Bewegungsspiel eine hohe Betriebssicherheit gewährleistet werden kann.In other words, it is thus provided that the tilting slide engages itself via its associated gripper on a roll of Rollenausziehführung. It can therefore be applied to additional and common in the prior art driver such. Hook or similarly shaped parts on which the tilting slide attacks, be waived. This saves on the one hand processing steps, on the other hand also parts. In addition, such a Rollenausziehführung can also be built very compact. A particular advantage, however, lies in the fact that, despite sufficient movement play, a high level of operational reliability can be ensured.
Günstigerweise ist vorgesehen, dass die Rolle an einer zweiten Schiene der Rollenausziehführung, vorzugsweise mittels einer an der zweiten Schiene befestigten Rollendrehachse, drehbar gelagert, vorzugsweise drehbar befestigt, ist. Es ist somit bevorzugt, dass zumindest eine Rolle an einer Schiene drehbar gelagert ist. Darüber hinaus können an den Schienen der Rollenausziehführung zusätzliche Rollen, vorzugsweise mittels ihrer Rollendrehachsen, drehbar gelagert bzw. befestigt sein. Die Rolle oder Rollen haben dabei bevorzugt eine tragende Funktion. Zusätzlich oder alternativ zu den genannten zusätzlichen Rollen können erfindungsgemäße Rollenausziehführungen aber auch mit an sich bekannten Laufwägen, in denen Kugeln und/oder Walzen drehbar gelagert sind, ausgeführt sein. Die Führungsschiene kann z.B. die Schiene sein, die am Möbelkorpus fixiert wird. Man nennt diese üblicherweise die Korpusschiene. Die zweite Schiene ist dann günstigerweise die Schiene der Rollenausziehführung, welche am relativ zum Möbelkorpus verschiebbar gelagerten Möbelteil befestigt wird. Die Führungsschiene und die zweite Schiene sind dann günstigerweise mittels der genannten Rollen und/oder Laufwägen verschiebbar ineinander gelagert. Auf zwei entgegengesetzten Seiten des Möbelteils kann je eine solche Rollenausziehführung angeordnet sein. Die Rollenausziehführung kann jeweils auch noch zumindest eine weitere Schiene z.B. eine Mittelschiene aufweisen, die sowohl zur Führungsschiene, als auch zur zweiten Schiene relativ bewegbar bzw. verschiebbar ist. Erfindungsgemäße Rollenausziehführungen können somit auch als an sich bekannte Differenzialausziehführungen ausgeführt werden. Eine Rollenausziehführung, bei der auf jeder Seite des Möbelteils drei Schienen verschiebbar zueinander, ineinander gelagert sind, ist an sich z.B. in der
Wie oben bereits ausgeführt, ist es ein wesentlicher Grundgedanke der Erfindung, dass der Kippschieber einen Greifer aufweist, welcher zum Einziehen des Möbelteils in der Einschubrichtung an der Rolle angreift. Das Einziehen des Möbelteils umfasst dabei zwei Abschnitte. Zunächst muss der Greifer des Kippschiebers an der Rolle angreifen. Dies wird im Folgenden als der Kontaktiervorgang bezeichnet. Daran anschließend erfolgt der eigentliche Einziehvorgang, in dem die Selbsteinzugsvorrichtung über den Kippschieber an der Rolle bzw. der damit verbundenen zweiten Schiene in Einschubrichtung zieht. Das oben genannte Einziehen des Möbelteils bezieht sich sowohl auf den Angreifvorgang als auch auf den Einziehvorgang. Nun kann in einer ersten Gruppe von Ausgeststtungsformen der Erfindung vorgesehen sein, dass sowohl der Kontaktiervorgang als auch der Einziehvorgang über den Eingriff des Greifers des Kippschiebers an der Rolle erfolgt. Ein Verfahren zum Betrieb solcher, erfindungsgemäßer Rollenausziehführungen kann dann vorsehen, dass der Kippschieber durch Auftreffen der Rolle auf den Greifer von einer ersten Kippstellung in die zweite Kippstellung gekippt wird, wobei durch dieses Kippen der Greifer und die Rolle miteinander in Eingriff gebracht werden und daran anschließend die Rolle am Greifer des Kippschiebers hängend vom Kippschieber in Einschubrichtung eingezogen wird. Bei dieser Vorgangsweise wird die zweite Schiene somit eingezogen, indem der Greifer direkt an der Rolle angreift und somit an der Rolle gezogen wird. Diese Varianten zeichnen sich dadurch aus, dass besonders wenige Teile benötigt werden. Sie können allerdings den Nachteil haben, dass durch das Anliegen des Greifers an der Rolle beim Einziehvorgang erhöhte Reibungskräfte auftreten.As already stated above, it is an essential basic idea of the invention that the tilting slide has a gripper which engages for retraction of the furniture part in the direction of insertion on the roller. The retraction of the furniture part includes two sections. First, the gripper of the tilting slide must engage the roller. This is referred to below as the contacting process. This is followed by the actual pulling-in process in which the self-closing device pulls over the tilting slide on the roller or the second rail connected thereto in the insertion direction. The above-mentioned retraction of the furniture part refers both to the attacking process as well as the Einziehvorgang. Now, in a first group of embodiments of the invention, it can be provided that both the contacting operation and the pulling-in operation are achieved by the engagement of the gripper of the gripper Tilting slide on the roller takes place. A method for operating such, according to the invention Rollenausziehführungen can then provide that the tilting slide is tilted by hitting the roller on the gripper from a first tilted position to the second tilted position, which is brought by this tilting of the gripper and the roller engaged with each other and thereafter the roller is pulled on the gripper of the tilting slide hanging from the tilting slide in the insertion direction. In this procedure, the second rail is thus retracted by the gripper acts directly on the roller and thus pulled on the roller. These variants are characterized by the fact that very few parts are needed. However, they can have the disadvantage that increased frictional forces occur as a result of the gripper engaging the roller during the pulling-in process.
Möchte man diese erhöhten Reibungskräfte vermeiden, so kann in einer zweiten Gruppe von Ausgestaltungsformen der Erfindung vorgesehen sein, dass das Angreifen des Greifers an der Rolle nur beim Kontaktiervorgang stattfindet. Es kann also auch vorgesehen sein, dass das Einziehen des Möbelteils in Einschubrichtung nur teilweise, also z. B. nur den Kontaktiervorgang umfassend, durch das Angreifen des Greifers an der Rolle erfolgt. Für den Einziehvorgang können bei diesen Varianten der Erfindung andere Mittel, mit denen der Kippschieber an der zweiten Schiene angreift, vorgesehen sein. In diesem Sinne sieht eine bevorzugte Gruppe von Ausgestaltungsformen der Erfindung vor, dass am Kippschieber ein erstes Kopplungsteil angeordnet ist und an der zweiten Schiene ein zweites Kopplungsteil angeordnet ist, wobei die Kopplungsteile in einer ersten Kippstellung des Kippschiebers voneinander gelöst sind und in einer zweiten Kippstellung des Kippschiebers miteinander in Eingriff stehen, wobei in der ersten Kippstellung die zweite Schiene und der Kippschieber in Ausziehrichtung und/oder in Einschubrichtung relativ zueinander bewegbar sind und in der zweiten Kippstellung die zweite Schiene und der Kippschieber bezüglich einer Bewegung in Ausziehrichtung und/oder in Einschubrichtung miteinander zwangsgekoppelt sind. Zwangsgekoppelt bedeutet in diesem Zusammenhang insbesondere, dass Schiene und Kippschieber in der zweiten Kippstellung nur gemeinsam in Ausziehrichtung und/oder in Einschubrichtung bewegt werden können. Ein Verfahren zum Betrieb einer solchen Rollenausziehführung kann dann vorsehen, dass der Kippschieber durch Auftreten der Rolle auf den Greifer von der ersten Kippstellung in die zweite Kippstellung gekippt wird, wobei durch dieses Kippen die Kopplungsteile miteinander in Eingriff gebracht werden und daran anschließend die zweite Schiene über die Kopplungsteile an dem Kippschieber hängend vom Kippschieber in Einschubrichtung gezogen wird. Bei diesen Varianten ist somit vorgesehen, dass das Kippen des Kippschiebers beim Kontaktiervorgang über das Angreifen des Greifers des Kippschiebers an der Rolle erfolgt, beim daran anschließenden Einziehvorgang aber der Kippschieber über die miteinander in Eingriff gebrachten Kopplungsteile direkt an der zweiten Schiene angreift, so dass das Gewicht der zweiten Schiene und des damit verbundenen einzuziehenden Möbelteils nicht mehr über den Greifer auf die Rolle wirkt. Hierdurch können die Reibungskräfte zwischen Rolle und Greifer beim Einziehvorgang minimiert bzw. ausgeschaltet werden.If one wishes to avoid these increased frictional forces, it can be provided in a second group of embodiments of the invention that the gripping of the gripper on the roller takes place only during the contacting process. It can therefore also be provided that the retraction of the furniture part in the insertion direction only partially, ie z. B. only the contacting process, takes place by the attack of the gripper on the roller. For the insertion process can be provided in these variants of the invention, other means with which the tilt slide on the second rail. In this sense, a preferred group of embodiments of the invention provides that on the tilt slide a first coupling part is arranged and on the second rail, a second coupling part is arranged, wherein the coupling parts are dissolved in a first tilted position of the tilting slide from each other and in a second tilted position of Tilting slide are engaged with each other, wherein in the first tilt position, the second rail and the tilt slide in the extension direction and / or in the insertion direction relative to each other are movable and in the second tilt position, the second rail and the tilt slide with respect to a movement in the pull-out direction and / or in the insertion direction with each other are positively coupled. Forced coupling means in this context, in particular, that rail and tilting slide can only be moved together in the pull-out direction and / or in the insertion direction in the second tilted position. A method for operating such a Rollenausziehführung may then provide that the toggle is tilted by the occurrence of the role on the gripper from the first tilted position to the second tilted position, this tilting the coupling parts are engaged with each other and then the second rail over the coupling parts is pulled on the tilting slide hanging from the tilting slide in the insertion direction. In these variants, it is thus provided that the tilting of the tilting slide takes place during the contacting process by engaging the gripper of the tilting slide on the roller, but during the subsequent retraction process the tilting slide engages directly on the second rail via the coupling parts engaged with one another, so that the Weight of the second rail and the associated piece of furniture to be recovered no longer acts on the roller via the gripper. As a result, the frictional forces between the roller and gripper can be minimized or eliminated during the pulling-in process.
Grundsätzlich kann der Greifer des Kippschiebers an verschiedenen Stellen an der Rolle angreifen. So ist z.B. denkbar, dass der Greifer des Kippschiebers an der Rollendrehachse der Rolle angreift. Besonders bevorzugt ist jedoch vorgesehen, dass die Rolle eine Lauffläche aufweist, mit der sie in der Führungsschiene läuft, und der Greifer des Kippschiebers an der Lauffläche der Rolle angreift. Dies ermöglicht eine besonders betriebssichere Rollenausziehführung die trotzdem mit viel Bewegungsspiel ausgestattet sein kann. Darüber hinaus ist dies auch eine sehr platzsparende Variante. Bevorzugt ist vorgesehen, dass der Greifer eine, vorzugsweise zumindest abschnittsweise z.B. kreisbogenförmig gebogene und/oder eine Vertiefung im Greifer begrenzende Greiferfläche aufweist, mit der er an, vorzugsweise der Lauffläche, der Rolle angreift. Damit der Greifer des Kippschiebers die Rolle sicher greifen kann, sehen bevorzugte Ausgestaltungsformen dabei vor, dass die Länge der Greiferfläche, gemessen in Ausziehrichtung, zumindest ein Achtel, vorzugsweise zumindest ein Viertel, des Gesamtumfangs der Lauffläche der Rolle beträgt. Dabei ist insbesondere der Teil der Greiferfläche in Betracht zu ziehen, der die Rolle tatsächlich umgreifen kann. Bei gebogenen Greiferflächen bezieht sich die Längenangabe auf eine Messung entlang der gebogenen Greiferfläche in Ausziehrichtung und nicht auf die in Ausziehrichtung verlaufende, gedachte Sehne zwischen den Endpunkten der Greiferfläche.In principle, the gripper of the tilting slide can attack at different points on the roller. For example, e.g. conceivable that the gripper of the tilting slide engages the roller rotation axis of the roller. Particularly preferably, however, it is provided that the roller has a running surface, with which it runs in the guide rail, and engages the gripper of the tilting slide on the running surface of the roller. This allows a particularly reliable roller extension guide which can still be equipped with a lot of movement play. In addition, this is also a very space-saving variant. It is preferably provided that the gripper one, preferably at least partially, e.g. has arcuately curved and / or a recess in the gripper limiting gripper surface, with which he attacks, preferably the tread, the roller. In order for the gripper of the tilting slide to be able to grasp the roller securely, preferred embodiments provide that the length of the gripper surface, measured in the withdrawal direction, is at least one-eighth, preferably at least a quarter, of the total circumference of the running surface of the roller. In particular, the part of the gripper surface is to be considered, which can actually embrace the role. In the case of curved gripper surfaces, the length specification refers to a measurement along the curved gripper surface in the pull-out direction and not to the pull-out, imaginary chord between the end points of the gripper surface.
Der Greifer kann eine Vertiefung zur Aufnahme der Rolle aufweisen, welche von zwei vorzugsweise gebogenen Greiferschenkeln begrenzt ist.The gripper may have a recess for receiving the roller, which is bounded by two preferably curved gripper legs.
Um die Rolle im Anschluss an eine evtl. auftretende Fehlfunktion der Rollenausziehführung wieder in die Position bewegen zu können, in der sie vom Greifer des Kipphebels umgriffen werden kann, sehen besonders bevorzugte Ausgestaltungsformen der Erfindung vor, dass zumindest einer der Greiferschenkel elastisch verformbar ausgebildet ist und eine zur Einschubrichtung schräge Anlaufschrägfläche aufweist, wobei die Rolle durch Anlaufen der Rolle gegen die Anlaufschrägfläche und durch elastisches Verformen des Greiferschenkels am Greiferschenkel vorbei in die Vertiefung des Greifers schiebbar ist.In order to move the role following a possibly occurring malfunction of Rollenausziehführung back into the position in which they can be gripped by the gripper of the rocker arm, particularly preferred embodiments of the invention provide that at least one of the gripper legs is formed elastically deformable and has an oblique to the insertion direction starting bevel, wherein the role is pushed by tarnishing the roller against the chamfering surface and by elastic deformation of the gripper leg on the gripper arm over into the recess of the gripper.
Um die Einfahrbewegung des bewegbaren Möbelteils beim Einziehen in Einschubrichtung zu dämpfen, ist es möglich, bei erfindungsgemäßen Rollenausziehführungen an sich bekannte Dämpfer für bewegliche Möbelteile zu integrieren. Eine besonders bevorzugte Ausgestaltungsform sieht dabei vor, dass am Kippschieber, vorzugsweise einstückig, ein Dämpferteil eines zumindest zwei relativ zueinander bewegbare Dämpferteile aufweisenden Dämpfers, vorzugsweise Rotationsdämpfers oder Lineardämpfers, angeordnet ist. Auch hierdurch wird die Zahl der Teile und der Platzbedarf minimiert.In order to dampen the retraction movement of the movable furniture part when pulling in the insertion direction, it is possible to integrate in accordance with the invention Rollenausziehführungen per se known dampers for movable furniture parts. A particularly preferred embodiment provides that on the tilting slide, preferably in one piece, a damper part of a damper having at least two mutually movable damper parts, preferably rotational damper or linear damper, is arranged. This also minimizes the number of parts and space requirements.

Der bei dieser Einzugsautomatik bzw. Selbsteinzugsvorrichtung 5 vorgesehene Kippschieber 6 bzw. dessen Greifer 7 weist zwei Greiferschenkel 15 auf. Diese begrenzen eine Vertiefung 11, die der Aufnahme der Rolle 4 dient. Die Greiferfläche 12 ist im gezeigten Ausführungsbeispiel zumindest abschnittsweise kreisförmig gebogen. Mit der Greiferfläche 12 greift der Greifer 7 an der Lauffläche 10 der Rolle 4 an. Der Biegeradius 13 des kreisförmigen Abschnitts der Greiferfläche 12 beträgt zwischen 100% und 110%, vorzugsweise zwischen 100% und 105%, des Radius 14 der Lauffläche 10 der Rolle 4. Es kann somit, wie eingangs erläutert, ein gewisses Spiel zwischen Rolle 4 und Greifer 7 vorgesehen sein, ohne dass dies die Betriebssicherheit der Selbsteinzugsvorrichtung 5 herabsetzen würde.The tilting
Der Kippschieber 6 weist in diesem Ausführungsbeispiel zwei in Ausziehrichtung 1 voneinander beabstandete Führungszapfen 17 und 18 auf. Mit diesen ist er in der Führungsbahn 20 des Gehäuses 25 verschiebbar zwangsgeführt. Die Führungsbahn 20 ist im gezeigten Ausführungsbeispiel nutförmig ausgebildet und wird von zwei einander gegenüberliegenden Seitenwänden 19 begrenzt. An ihrem in Einschubrichtung 2 gesehen vorderen Ende weist die Führungsbahn 20 einen abgewinkelten bzw. abgebogenen Abschnitt 21 auf, ansonsten verläuft sie günstigerweise linear. In den abgewinkelten Abschnitt 21 ist ein erster, hier der in Einschubrichtung 2 vordere, Führungszapfen 17 einschiebbar. Der bei diesem Ausführungsbeispiel vorhandene zweite Führungszapfen 18 bildet eine Schwenkachse, um die der Kippschieber 6 schwenkt, wenn der erste Führungszapfen 17 in den abgewinkelten Abschnitt 21 eingeschoben wird. Im Ergebnis dieser Schwenkbewegung kommt der Kippschieber 6 in die, in den
Wie bereits eingangs erläutert, ist der Dämpfer 24 mit seinem Dämpferteil 23 (hier dem Dämpfergehäuse) einstückig am Kippschieber 6 befestigt. Dies bewirkt, dass die von der Feder 31 durchgeführte automatische Einzugsbewegung gleichzeitig vom Dämpfer 24 gedämpft wird. Dies bewirkt in Summe ein sanftes Abbremsen der Einzugsbewegung, sodass die Rolle 4, die Schiene 8 und das daran befestigte Möbelteil bei Erreichen des Endanschlags 33 sanft und nicht ruckartig abgebremst werden. Im gezeigten Ausführungsbeispiel kämmt der relativ zum Dämpferteil bzw. dem Dämpfergehäuse 23 drehbar gelagerte Dämpferteil 22 mit der Zahnstange 29. Weitere Details zum Dämpfer 24 müssen nicht dargestellt werden, da sie beim Stand der Technik bekannt sind. Der Vollständigkeit halber sei darauf hingewiesen, dass der Dämpfer 24 natürlich nicht zwingend einstückig am Kippschieber 6 angeordnet sein muss.As already explained above, the

Ein erster wesentlicher Unterschied zu den ersten beiden Ausführungsbeispielen besteht beim dritten Ausführungsbeispiel darin, dass das Gehäuse 25' dieses Ausführungsbeispiels keine u-förmige Ausnehmung 26 aufweist, sondern, vorzugsweise vollständig, in einer Betriebsstellung der Rollenausziehführung gesehen, oberhalb der Führungsschiene 3 angeordnet ist. Genauso gut kann es natürlich auch, vorzugsweise vollständig, unterhalb der Führungsschiene 3 angeordnet sein. Beide Varianten haben den Vorteil, dass insgesamt die Baulänge der Rollenausziehführung verkürzt wird, da das Gehäuse 25' nicht mehr am hinteren Ende über die Führungsschiene 3 übersteht. Im Zuge dessen ist bei dem gezeigten Ausführungsbeispiel auch vorgesehen, dass die Feder 31, welche die Kraft zum Einziehen der Rolle 4 bzw. der zweiten Schiene 8 zur Verfügung stellt, nicht mehr umgelenkt ist. Im gezeigten Ausführungsbeispiel weist die Feder 31 eine ausschließlich lineare Erstreckung auf. Die Feder 31 ist dabei, vorzugsweise ausschließlich, oberhalb der Führungsschiene 3 angeordnet. Auch sie steht in Einschubrichtung 2 nicht über die Führungsschiene 3 über. Genauso gut kann die Feder 31 aber auch, vorzugsweise ausschließlich, unterhalb der Führungsschiene 3 angeordnet sein.A first essential difference to the first two embodiments is in the third embodiment is that the housing 25 'of this embodiment has no
Das Gehäuse 25' der Selbsteinzugsvorrichtung 5 dieses Ausführungsbeispiels ist zweiteilig aufgebaut. Es weist einen an der Führungsschiene 3 unverschiebbar fixierten Gehäuseteil 38 auf. Dieser weist in diesem Ausführungsbeispiel wiederum eine Gehäuseschiene 39 auf, auf der ein als Schubstange 35 ausgebildeter Verbindungskörper relativ zum fixierten Gehäuseteil 38, vorzugsweise parallel zur Ausziehrichtung 1 bzw. Einschubrichtung 2, verschiebbar gelagert ist. Wie insbesondere in den Schnittdarstellungen gem.
Der Kippschieber 6 ist, wie auch bei den ersten Ausführungsbeispielen, mittels des ersten Führungszapfens 17 und des Schwenkachszapfens 18 in einer Führungsbahn 20 geführt, welche an ihrem in Einschubrichtung 2 gesehen vorderen Ende den abgewinkelten Bereich 21 aufweist. Die Führung und das Verkippen des Kippschiebers 6 mittels der Führungsbahn 2 und ihres abgewinkelten Abschnittes 21 erfolgt wie bei den beiden zuerst dargelegten Ausführungsbeispielen. Die Kippbewegung erfolgt im Schwenkgelenk 34.The tilting

Zu erwähnen ist noch die Anlaufschrägfläche 16 des in Einschubrichtung 2 gesehen vorderen Greiferschenkels 15 des Kippschiebers 6. Diese dient, analog wie bei den ersten beiden Ausführungsbeispielen beschrieben, der sogenannten Fehlfunktionssicherung, bei der die Rolle 4 in der zweiten Kippstellung des Kippschiebers 6 durch Anlaufen gegen die Anlaufschrägfläche 16 und durch elastisches Verformen des Greiferschenkels 15 an diesem vorbei in die Vertiefung 11 des Greifers 7 schiebbar ist.To mention is still the starting
