Die Figur 1 zeigt eine Einzugsvorrichtung (10). Derartige Einzugsvorrichtungen (10) werden eingesetzt, um beispielsweise relativ zum feststehenden Möbelkorpus bewegliche Möbelstückteile, z.B. Schiebetüren, Schubladen, etc. gesteuert in ihre Endlage zu bewegen. Hierbei werden die beweglichen Möbelstückteile vor dem Erreichen der z.B. geschlossenen Endlage mit einer resultierenden Kraft einer kombinierten Beschleunigungs- und Verzögerungsvorrichtung (20) beaufschlagt, sodass sie mit geringer Geschwindigkeit und ohne anzuschlagen ihre Endlage erreichen.The FIG. 1 shows a collection device (10). Such retraction devices (10) are used to move, for example, relative to the fixed furniture body movable furniture pieces, eg sliding doors, drawers, etc. controlled in their final position. In this case, the movable piece of furniture pieces are subjected before reaching the eg closed end position with a resultant force of a combined acceleration and deceleration device (20) so that they reach their end position at low speed and without striking.

Die Einzugsvorrichtung (10) umfasst die kombinierte Beschleunigungs- und Verzögerungsvorrichtung (20) und einen Mitnehmer (90). Hierbei sind beispielsweise die kombinierte Beschleunigungs- und Verzögerungsvorrichtung (20) am beweglichen Möbelstückteil und der Mitnehmer (90) am feststehenden Möbelkorpus angeordnet. Es ist aber auch denkbar, den Mitnehmer (90) am beweglichen Möbelstückteil und die Beschleunigungs- und Verzögerungsvorrichtung (20) am feststehenden Möbelkorpus anzuordnen.The collection device (10) comprises the combined acceleration and deceleration device (20) and a driver (90). Here, for example, the combined acceleration and deceleration device (20) on the movable furniture piece part and the driver (90) are arranged on the fixed furniture body. But it is also conceivable to arrange the driver (90) on the movable furniture piece part and the acceleration and deceleration device (20) on the fixed furniture body.

Die Beschleunigungs- und Verzögerungsvorrichtung (20) umfasst ein Tragteil (21) und ein entlang des Tragteils (21) geführtes Mitnahmeelement (31). Das Tragteil (21) hat eine stetige Führungsfläche (22), entlang der das Mitnahmeelement (31) von einer kraft- und/oder formschlüssigen Parkposition in eine Endposition und zurück führbar ist. Das Mitnahmeelement (31) ist mit einer Kolbenstange (65) einer im Tragteil (21) gelagerten Zylinder-Kolben-Einheit (61) und mit einem am Tragteil (21) befestigten Energiespeicher (81) verbunden. Hierbei belastet der Energiespeicher (81) das Mitnahmeeelement (31) entgegen der Wirkung der Zylinder-Kolben-Einheit (61) in Richtung der Parkposition.The acceleration and deceleration device (20) comprises a carrier part (21) and a carrier element (31) guided along the carrier part (21). The support member (21) has a continuous guide surface (22), along which the entrainment element (31) can be guided from a non-positive and / or positive parking position into an end position and back. The entrainment element (31) is connected to a piston rod (65) of a cylinder-piston unit (61) mounted in the support part (21) and to an energy store (81) attached to the support part (21). In this case, the energy store (81) loads the driving element (31) against the action of the cylinder-piston unit (61) in the direction of the parking position.

Die Führungsfläche (22) des Tragteils (21) umfasst einen Führungsabschnitt (23) und einen Halteabschnitt (25). Beide z.B. normal zueinander angeordneten Abschnitte (23, 25) sind mittels eines Bogenabschnittes (24) miteinander verbunden. Der Halte- (25) und der Bogenabschnitt (24) sind Teil einer Führungsnut (26), die im Endbereich eine Aufweitung (27) aufweist, vgl. Figur 4.The guide surface (22) of the support part (21) comprises a guide portion (23) and a holding portion (25). Both, for example, normal to each other arranged portions (23, 25) by means of an arc section (24) are interconnected. The holding (25) and the arc section (24) are part of a guide groove (26) which has an expansion (27) in the end region, cf. FIG. 4 ,

Die Figur 2 zeigt das Mitnahmeelement (31). Das Mitnahmeelement (31) übergreift das Tragteil (21) mittels zweier Gleitelemente (32, 33). Diese Gleitelemente (32, 33) verbinden einen Führungs- und Aufnahmebereich (34) und einen Mitnahmebereich (35). Sie sind voneinander beabstandet und liegen an der Führungsfläche (22) an.The FIG. 2 shows the driving element (31). The driving element (31) engages over the supporting part (21) by means of two sliding elements (32, 33). These sliding elements (32, 33) connect a guiding and receiving area (34) and a driving area (35). They are spaced apart and abut against the guide surface (22).

Der Mitnahmebereich (35) umfasst einen Schubzapfen (36) und einen Zugzapfen (38). Hierbei umfasst der Schubzapfen (36) das in Richtung der Endposition zeigende Ende des Mitnahmeeelements (31). Der Schubzapfen (36) begrenzt mit einer Schubfläche (37) und der Zugzapfen (38) begrenzt mit einer Zugfläche (39) eine Mitnahmeelementausnehmung (41). Die Schubfläche (37) und die Zugfläche (39) sind beispielsweise einander zugewandt. Im Ausführungsbeispiel schließen die Ebenen der Schubfläche (37) und der Zugfläche (39) einen Winkel von 35 Grad ein. Die Mitnahmeelementausnehmung (41) ist weiterhin mittels einer Bodenfläche (42) begrenzt, die z.B. parallel zur Tangentialebene der Gleitelemente (32, 33) ausgerichtet ist. Der z.B. in einer Unteransicht der Beschleunigungs- und Verzögerungsvorrichtung (61) dreiecksförmig ausgebildete Zugzapfen (38) ist elastisch, z.B. filmgelenkartig verformbar.The driving area (35) comprises a push pin (36) and a pull pin (38). In this case, the push pin (36) comprises the end of the driving element (31) pointing in the direction of the end position. The push pin (36) delimited by a thrust surface (37) and the traction pin (38) limited with a tension surface (39) has a Mitnahmeelementausnehmung (41). The thrust surface (37) and the traction surface (39), for example, facing each other. In the embodiment, the planes of the thrust surface (37) and the traction surface (39) subtend an angle of 35 degrees. The entrainment element recess (41) is further bounded by a bottom surface (42), e.g. is aligned parallel to the tangential plane of the sliding elements (32, 33). The e.g. in a bottom view of the acceleration and deceleration device (61), triangularly shaped traction pins (38) are elastic, e.g. deformable like a film joint.

Der Schubzapfen (36) hat einen die Schubfläche (37) umfassenden Schubsteg (43), der an einem Bodensteg (44) und an einem gebogen ausgebildeten Kopfsteg (45) abgestützt ist. Der Kopfsteg (45) und der Bodensteg (44) sind an ihrem dem Schubsteg (43) abgewandten Ende miteinander verbunden. Alle drei genannten Stege (43 - 45) haben im Ausführungsbeispiel die gleiche Dicke. In dem von den drei genannten Stegen (43 - 45) gebildeten Zwischenraum ist ein Längssteg (46) angeordnet. Die Dicke des Längsstegs (46) beträgt beispielsweise 80 % der Dicke der übrigen Stege (43 - 45). Er ist im Ausführungsbeispiel einseitig bündig mit den übrigen Stegen (43 - 45). Es ist auch denkbar, den Längssteg (46) dünner auszubilden und/oder diesen mittig zu den anderen Stegen (43 - 45) anzuordnen. Auch eine Ausbildung des Schubzapfens (36) ohne Längssteg (46), ohne Kopfsteg (45) oder ohne Bodensteg (44) ist denkbar. Die Schubfläche (37) des Schubstegs (43) ist Teil einer Grenzschicht (51). Die Dicke dieser Grenzschicht (51), in der der Werkstoff homogen ist, beträgt mindestens 1,5 Millimeter. Im Ausführungsbeispiel ist das gesamte Mitnahmeelement (31) aus einem thermoplastischen Kunststoff, z.B. Polyoxymethylen (POM), hergestellt. Dieser Werkstoff hat beispielsweise eine Härte zwischen 65 Shore D und 85 Shore D. Sein Elastizitätzsmodul bei Raumtemperatur beträgt zwischen 1500 Newton pro Quadratmillimeter und 3000 Newton pro Quadratmillimeter. Als Elastizitätsmodul ist hier der sogenannte Kurzzeit-Elastizitätsmodul bezeichnet, der bei einer Belastung in einem Zeitintervall unter 10 Minuten ermittelt wird. Der genannte Elastizitätsmodul ist der Druck-Elastizitätsmodul bei einer Kompression zwischen 0,5 % und 1 %, der bei dem genannten Werkstoff z.B. 15 % niedriger ist als der Zug-Elastizitätsmodul bei einer Dehnung zwischen 0,5 % und 1 %.The push pin (36) has a thrust surface (37) comprising the push bar (43) which is supported on a bottom web (44) and on a curved head restraint (45). The head web (45) and the bottom web (44) are connected to each other at its end facing away from the push bar (43). All three said webs (43-45) have the same thickness in the embodiment. In the intermediate space formed by the three webs (43-45), a longitudinal web (46) is arranged. The thickness of the longitudinal web (46) is for example 80% of the thickness of the remaining webs (43-45). He is in the embodiment on one side flush with the other webs (43 - 45). It is also conceivable to make the longitudinal web (46) thinner and / or to arrange it centrally relative to the other webs (43-45). A design of the thrust pin (36) without longitudinal ridge (46), without head ridge (45) or without bottom web (44) is conceivable. The thrust surface (37) of the push bar (43) is part of a boundary layer (51). The thickness of this boundary layer (51), in which the material is homogeneous, is at least 1.5 millimeters. In the exemplary embodiment, the entire entrainment element (31) is made of a thermoplastic, for example polyoxymethylene (POM). For example, this material has a hardness between 65 Shore D and 85 Shore D. Its elasticity modulus at room temperature is between 1500 Newton per square millimeter and 3000 Newton per square millimeter. The modulus of elasticity here refers to the so-called short-term elastic modulus, which is determined under load during a time interval of less than 10 minutes. The said modulus of elasticity is the compressive modulus at a compression between 0.5% and 1%, which is for example 15% lower for the said material than the tensile elastic modulus for an elongation between 0.5% and 1%.

Es ist auch denkbar, die Grenzschicht (51) aus einem Werkstoff mit einem geringeren Elastizitätsmodul auszuführen als den Rest des Mitnahmeeelements (31). Die Grenzschicht (51) kann beispielsweise aus einem elastomerem Werkstoff bestehen, der auf den Tragkörper (47) des Mitnahmeelements (31) aufvulkanisiert ist. Ein derartiger Werkstoff kann z.B. Nitril-Buatadien-Kautschuk (NBR) sein, dessen Elastizitätsmodul unter den oben genannten Bedingungen zwischen 4 Newton pro Quadratmillimeter und 20 Newton pro Quadratmillimeter liegt.It is also conceivable to design the boundary layer (51) of a material with a lower modulus of elasticity than the rest of the driving element (31). The boundary layer (51) may for example consist of an elastomeric material which is vulcanized onto the support body (47) of the driving element (31). Such a material may e.g. Nitrile-buatadiene rubber (NBR) whose modulus of elasticity is between 4 Newton per square millimeter and 20 Newton per square millimeter under the conditions mentioned above.

Der Schubsteg (43) kann einen zumindest annähernd rechteckigen Querschnitt aufweisen. Er kann als Voll- oder als Hohlmaterial ausgebildet sein. Auch eine im Querschnitt u-förmige oder T- oder Doppel-T-förmige Ausbildung ist denkbar, wobei ein Schenkel des U oder ein Gurt des T die Schubfläche (37) um-fasst. Die Dicke des Schubstegs (43) kann größer sein als das oben angegebene Maß.The push bar (43) can have an at least approximately rectangular cross-section. It can be configured as a solid or as a hollow material. A cross-sectionally U-shaped or T- or double-T-shaped design is also conceivable, with one leg of the U or a belt of the T encompassing the thrust face (37). The thickness of the push bar (43) may be greater than the above dimension.

Der Führungs- und Aufnahmebereich (34) umfasst eine Federaufnahme (48) und eine Kolbenstangenaufnahme (49). Beide Aufnahmen (48, 49) zeigen im Ausführungsbeispiel in Richtung der Endposition. In der Federaufnahme (48) ist ein Ende des Energiespeichers (81) der Beschleunigungs- und Verzögerungsvorrichtung (20) eingehängt. Im Ausführungsbeispiel ist der Energiespeicher (81) als Zugfeder (81) ausgebildet. Das andere Ende der Zugfeder (81) ist im Tragteil (21) gelagert.The guiding and receiving region (34) comprises a spring receptacle (48) and a piston rod receptacle (49). Both recordings (48, 49) show in the embodiment in the direction of the end position. In the spring receptacle (48) one end of the energy store (81) of the acceleration and deceleration device (20) is mounted. In the exemplary embodiment, the energy store (81) is designed as a tension spring (81). The other end of the tension spring (81) is mounted in the support part (21).

In der Figur 4 ist ein Längsschnitt der Beschleunigungs- und Verzögerungsvorrichtung (20) dargestellt. In der Kolbenstangenaufnahme (49) des Mitnahmeelements (31) ist der Kolbenstangenkopf (66) der Kolbenstange (65) der Zylinder-Kolben-Einheit (61) schwenkbar gelagert. Die Zylinder-Kolben-Einheit (61) umfasst einen Zylinder (62) und einen in diesem mittels einer Kolbenstange (65) geführten Kolben (67). Der Zylinder (62) ist mittels eines geschlossenen Bodens (63) verschlossen. Die Innenwandung des Zylinders (62) kann zylindrisch oder konisch ausgebildet sein. Die Zylinderinnenwandung hat beispielsweise zwei in Längsrichtung orientierte Nuten unterschiedlicher Länge, die beide an den Zylinderboden (63) angrenzen. Beispielsweise beträgt die Länge der kurzen Längsnut ein Viertel der Länge des Zylinders. Die Länge der langen Längsnut beträgt z.B. drei Viertel der Länge des Zylinders (62). Am kolbenstangenseitigen Ende ist der Zylinder (62) am Zylinderkopf (64) mittels einer Kolbenstangendichtung verschlossen.In the FIG. 4 a longitudinal section of the acceleration and deceleration device (20) is shown. In the piston rod receptacle (49) of the driving element (31) of the piston rod head (66) of the piston rod (65) of the cylinder-piston unit (61) is pivotally mounted. The cylinder-piston unit (61) comprises a cylinder (62) and a piston (67) guided therein by means of a piston rod (65). The cylinder (62) is closed by means of a closed bottom (63). The inner wall of the cylinder (62) may be cylindrical or conical. The cylinder inner wall has, for example, two longitudinally oriented grooves of different lengths, both of which adjoin the cylinder bottom (63). For example, the length of the short longitudinal groove is a quarter of the length of the cylinder. The length of the long longitudinal groove is for example three quarters of the length of the cylinder (62). At the piston rod end, the cylinder (62) on the cylinder head (64) is closed by means of a piston rod seal.

Der Kolben (67) hat im Ausführungsbeispiel eine Kolbendichtung (68) mit einer in Richtung des Zylinderbodens (63) orientierten Dichtlippe. Der Kolben (67) kann einteilig mit der Kolbenstange (65) und/oder mit der Kolbendichtung (68) ausgebildet sein.In the exemplary embodiment, the piston (67) has a piston seal (68) with a sealing lip oriented in the direction of the cylinder bottom (63). The piston (67) may be formed integrally with the piston rod (65) and / or with the piston seal (68).

Der Mitnehmer (90) ist in der Darstellung der Figur 1 an einer Türschiene (110) des Möbelkorpus angeordnet. Er ist dort beispielsweise mittels zweier Schrauben (111) befestigt. Der Abstand des Mitnehmers (90) von der vertikalen Türzarge, an der die geschlossene Schiebetür anliegt, ist kleiner als der in Längsrichtung (15) gemessene Abstand zwischen der Parkposition und der Endposition. Als Längsrichtung (15) ist hierbei die Längsrichtung (15) der Beschleunigungs- und Verzögerungsrichtung (20) bezeichnet, in der z.B. auch die Schiebetür orientiert ist.The driver (90) is in the representation of FIG. 1 arranged on a door rail (110) of the furniture body. He is there, for example, by means of two screws (111) attached. The distance of the driver (90) from the vertical door frame, on which the closed sliding door rests, is smaller than the longitudinal direction (15) measured distance between the parking position and the end position. As a longitudinal direction (15) in this case the longitudinal direction (15) of the acceleration and deceleration direction (20) is designated in the example, the sliding door is oriented.

In der Figur 3 ist der Mitnehmer (90) dargestellt. Dies ist ein in Längsrichtung (15) der Beschleunigungs- und Verzögerungsrichtung (20) orientiertes Bauteil, das im Ausführungsbeispiel symmetrisch zu seiner Mittenquerebene ausgebildet ist. Der Mitnehmer (90) hat an seiner der Beschleunigungs- und Verzögerungsvorrichtung (20) zugewandten Längsseite zwei außenliegende Anschlagzapfen (91, 92) und zwei innenliegende Führungszapfen (93, 94). Zwischen den Anschlagzapfen (91, 92) und den Führungszapfen (93, 94) ist jeweils eine Rastkerbe (95) angeordnet.In the FIG. 3 the driver (90) is shown. This is a component oriented in the longitudinal direction (15) of the acceleration and deceleration direction (20) and, in the exemplary embodiment, is formed symmetrically with respect to its central transverse plane. The driver (90) has on its the acceleration and deceleration device (20) facing the longitudinal side two outer stop pins (91, 92) and two inner guide pins (93, 94). Between the stop pins (91, 92) and the guide pins (93, 94) in each case a latching notch (95) is arranged.

In der Figur 1 ist der Mitnehmer (90) mit einer linksseitigen Beschleunigungs- und Verzögerungssvorrichtung (20) dargestellt. Linksseitig bedeutet hier, dass bei einer Ansicht der Beschleunigungs- und Verzögerungsrichtung (20) von der Parkposition in Richtung der Endposition das untenliegende Mitnahmeelement (31) nach links aus der Beschleunigungs- und Verzögerungsvorrichtung (20) heraussteht. Beispielsweise ist in dieser Ansicht der Innenraum des Schranks links von der Beschleunigungs- und Verzögerungsvorrichtung (20) angeordnet. Beim Einsatz mit einer linksseitigen Beschleunigungs- und Verzögerungsvorrichtung (20) kommen der in der Figur 1 linke Anschlagzapfen (91) und der linke Führungszapfen (93) zum Einsatz. Beim Einsatz mit einer rechtsseitigen Beschleunigungs- und Verzögerungsvorrichtung werden der in der Figur 1 rechte Anschlagzapfen (92) und der rechte Führungszapfen (94) eingesetzt.In the FIG. 1 the carrier (90) is shown with a left-side acceleration and deceleration device (20). On the left side means here that in a view of the acceleration and deceleration direction (20) from the parking position in the direction of the end position, the underlying driving element (31) to the left from the acceleration and Delay device (20) protrudes. For example, in this view, the interior of the cabinet is located to the left of the acceleration and deceleration device (20). When used with a left-side acceleration and deceleration device (20) come in the FIG. 1 left stopper pin (91) and the left guide pin (93) used. When used with a right-side acceleration and deceleration device in the FIG. 1 right stop pin (92) and the right guide pin (94) used.

Der einzelne Anschlagzapfen (91; 92) umfasst eine außenliegende Mitnahmefläche (96). Diese Mitnahmefläche (96) ist Teil einer Grenzschicht (97), deren Dicke mindestens 1,5 Millimeter beträgt. Die Mitnahmefläche (96) hat beispielsweise einen zentralen ebenen Abschnitt, an den sich konvex gewölbte Übergangsabschnitte anschließen. Die Grenzschicht (97) kann auch den gesamten Anschlagzapfen (91; 92) oder den gesamten Mitnehmer (90) umfassen. Bei einer Ausbildung des Anschlagzapfens (91; 92) als Grenzschicht (97) hat diese beispielsweise eine Dicke, die kleiner ist als 10 Millimeter.The single stop pin (91, 92) comprises an outer driving surface (96). This driving surface (96) is part of a boundary layer (97) whose thickness is at least 1.5 millimeters. The driving surface (96) has, for example, a central planar section, adjoined by convexly curved transition sections. The boundary layer (97) can also comprise the entire stop pin (91; 92) or the entire catch (90). In an embodiment of the stop pin (91; 92) as a boundary layer (97), for example, this has a thickness which is less than 10 millimeters.

Der einzelne Führungszapfen (93; 94) hat eine dem zweiten Führungszapfen (94; 93) zugewandte Anlagefläche (98). Die Anlagefläche (98) hat einen ebenen Bereich, an den sich konvex gewölbte Flächenabschnitte anschließen. Die Anlagefläche (98) kann Teil einer Grenzschicht sein.The single guide pin (93, 94) has a contact surface (98) facing the second guide pin (94, 93). The contact surface (98) has a flat area, which is followed by convex curved surface sections. The contact surface (98) may be part of an interface.

Im Ausführungsbeispiel ist der gesamte Mitnehmer (90) aus einem thermoplastischen Elastomer, z.B. Polypropelen, Polyethylen, etc. hergestellt. Diese Werkstoffe haben einen Elastizitätsmodul zwischen 1000 Newton pro Quadratmillimeter und 1500 Newton. Die Definition des Elastizitätsmoduls entspricht der oben genannten Definition. Die Härte dieses Werkstoffs beträgt beispielsweise zwischen 60 Shore A und 85 Shore A. Es ist auch denkbar, den Mitnehmer aus einem thermoplastischen Urethan, z.B. Polyurethan, oder aus einem elastomerem Werkstoff, z.B. Nitril-Butadien-Kautschuk (NBR) herzustellen.In the exemplary embodiment, the entire carrier (90) is made of a thermoplastic elastomer, for example polypropylene, polyethylene, etc. These materials have a modulus of elasticity between 1000 Newton per square millimeter and 1500 Newton. The definition of the modulus of elasticity corresponds the above definition. The hardness of this material is, for example, between 60 Shore A and 85 Shore A. It is also conceivable to produce the carrier from a thermoplastic urethane, for example polyurethane, or from an elastomeric material, for example nitrile-butadiene rubber (NBR).

Der Mitnehmer (90) kann auch derart aufgebaut sein, dass nur die Grenzschicht (97) aus dem thermoplastischen Elastomer, dem thermoplastischen Urethan oder dem elastomerem Werkstoff hergestellt ist. Der Werkstoff des die Grenzschicht (97) tragenden Trägers kann dann beispielsweise ein Stahlwerkstoff, ein duroplastischer Werkstoff oder ein thermoplastischer Werkstoff sein. Auf diesen kann die Grenzschicht (97) dann z.B. vulkanisiert sein.The driver (90) may also be constructed such that only the barrier layer (97) is made of the thermoplastic elastomer, thermoplastic urethane or elastomeric material. The material of the boundary layer (97) bearing carrier can then be for example a steel material, a thermoset material or a thermoplastic material. On top of this, the boundary layer (97) may then be e.g. be vulcanized.

Der Abstand der Anlagefläche (98) undder Mitnahmefiäche (96) kann kleiner sein als der Abstand der Zugfläche (39) von der Schubfläche (37). Es ist aber auch denkbar, dass die Abstände gleich groß sind oder dass zur Bildung einer Presspassung der Abstand der Anlagefläche (98) zur Mitnahmefläche (96) geringfügig größer ist als der Abstand der Zugfläche (39) von der Schubfläche (37).The distance of the abutment surface (98) and the driving surface (96) may be smaller than the distance of the traction surface (39) from the thrust surface (37). But it is also conceivable that the distances are the same size or that to form a press fit, the distance of the contact surface (98) to the driving surface (96) is slightly greater than the distance of the tension surface (39) of the thrust surface (37).

Bei der Montage wird die Beschleunigungs- und Verzögerungsvorrichtung (20) beispielsweise an der Schiebetür und der Mitnehmer (90) an der Türschiene (110) befestigt. Die Schiebetür ist dann in der Längsrichtung (15) relativ zum Mitnehmer (90) zwischen einer offenen und einer geschlossenen Stellung verfahrbar.During assembly, the acceleration and deceleration device (20), for example, on the sliding door and the driver (90) attached to the door rail (110). The sliding door is then movable in the longitudinal direction (15) relative to the driver (90) between an open and a closed position.

Nach der Inbetriebnahme steht bei geöffneter Schiebetür das Mitnahmeelement (31) in der Parkposition. Hierbei steht das der Zylinder-Kolben-Einheit (20) abgewandte Gleitelement (32) im Halteabschnitt (25) der Führungsfläche (22). Es ist dort mittels der gespannten Zugfeder (81) gesichert. Das andere Gleitelement (33) steht im Führungsabschnitt (23). Die Kolbenstange (65) der Zylinder-Kolben-Einheit (61) ist ausgefahren.After startup, the entrainment element (31) is in the parking position when the sliding door is open. Here, the cylinder-piston unit (20) facing away sliding member (32) in the holding section (25) of the guide surface (22). It is secured there by means of the tensioned tension spring (81). The other sliding element (33) is in the guide section (23). The piston rod (65) of the cylinder-piston unit (61) is extended.

Beispielsweise beim Schließen der Schiebetür kontaktiert das Mitnahmeelement (31) mit der Schubfläche (37) die Mitnahmefläche (96) des Mitnehmers (90). Der Mittelwert des Elastizitätsmoduls der beiden, die jeweiligen Flächen (37, 96) umfassenden Grenzschichten (51, 97) liegt in einem Bereich zwischen 700 Newton pro Quadratmillimeter und 1600 Newton pro Quadratmillimeter. Beim Kontaktieren der beiden Grenzschichten (51, 97) wird zumindest die Grenzschicht (51; 97) mit dem geringeren Elastizitätsmodul elastisch verformt. Beim Kontaktieren entsteht damit kein Schlaggeräusch.For example, when closing the sliding door, the driving element (31) with the thrust surface (37) contacts the driving surface (96) of the driver (90). The average elastic modulus of the two boundary layers (51, 97) comprising the respective faces (37, 96) is in a range of between 700 Newton per square millimeter and 1600 Newton per square millimeter. When the two boundary layers (51, 97) are in contact, at least the boundary layer (51, 97) with the lower modulus of elasticity is elastically deformed. When contacting this creates no impact noise.

Bei der Fortsetzung der Schließbewegung wird das Mitnahmeeelement (31) aus der Parkposition in den geraden Führungsabschnitt (23) geschwenkt. Hierbei kann der Zugzapfen (38) den Mitnehmer (90) an der Anlagefläche (98) berühren. Der Mitnehmer (90) kann in die Mitnahmeelementausnehmung (41) quasi eingeklemmt werden. Bei der Ausbildung der Anlagefläche (98) und/oder der Zugfläche (39) als Teil einer Grenzschicht mit einem Elastizitätsmodul unterhalb 1500 Newton pro Quadratmillimeter entsteht auch bei diesem Anlegen kein Anschlaggeräusch.In the continuation of the closing movement, the entrainment element (31) is pivoted from the parking position into the straight guide section (23). In this case, the tensioning pin (38) can contact the carrier (90) on the contact surface (98). The driver (90) can be virtually clamped in the driving element recess (41). In the formation of the contact surface (98) and / or the tension surface (39) as part of a boundary layer with a modulus of elasticity below 1500 Newton per square millimeter, no impact noise arises even with this application.

Es ist auch denkbar, bei einem Zugzapfen (38) mit einem Filmgelenk dieses beim Anlegen an den Mitnehmer (90) zu verformen. Auch bei einer derartigen Ausführungsform kann nach dem Kippen des Mitnahmeeelements (31) in den geraden Führungsabschnitt (23) der Mitnehmer (90) in die Mitnahmeelementausnehmung (41) des Mitnahmeelements (31) eingeklemmt sein.It is also conceivable, in the case of a traction pin (38) with a film joint, to deform this during application to the carrier (90). Even with such an embodiment, after the tilting of the driving element (31) into the straight guide section (23), the catch (90) can be clamped into the driving element recess (41) of the driving element (31).

Nach dem Kippen des Mitnahmeelements (31) aus der Parkposition wird der Energiespeicher (81) entlastet und zieht das Mitnahmeelement (31) in Richtung der Endposition. Die Schiebetür wird damit z.B. in die geschlossene Stellung gezogen. Gleichzeitig verschiebt das relativ zum Zylinder (62) bewegte Mitnahmeelement (31) den Kolben (67) in den Zylinder (62) hinein. Die Dichtlippe der Kolbendichtung (68) legt sich schlagartig an die Zylinderinnenwandung an und dichtet im Zylinderinnenraum einen Verdrängungsraum gegen einen Ausgleichsraum quasi hermetisch ab. Die Schiebetür wird abgebremst. Sobald z.B. beim weiteren Schließen der Schiebetür der Kolben (67) die erste Längsnut der Zylinderinnenwandung überfährt, wird z.B. Gas entlang dieser Drosselnut aus dem Verdrängungsraum in den Ausgleichsraum verdrängt. Die Bewegung der Schiebetür wird durch die mittels des Energiespeichers (81) aufgebrachte Beschleunigung und durch die gleichzeitig mittels der Zylinder-Kolben-Einheit (61) bewirkte Verzögerung bestimmt. Sobald der Kolben (67) die kurze Längsnut überfährt, wird die Verzögerungsrate weiter verringert. Die Schiebetür verfährt langsam in ihre geschlossene Endlage. Dort bleibt sie ruckfrei stehen.After tilting the carrier element (31) from the parking position, the energy store (81) is relieved and pulls the carrier element (31) in the direction of the end position. The sliding door is thus replaced e.g. pulled into the closed position. At the same time, the driving element (31) moved relative to the cylinder (62) displaces the piston (67) into the cylinder (62). The sealing lip of the piston seal (68) abruptly abuts against the cylinder inner wall and seals in the cylinder interior a displacement chamber against a compensation chamber quasi hermetically. The sliding door is slowed down. As soon as e.g. on further closing the sliding door of the piston (67) passes over the first longitudinal groove of the cylinder inner wall, is e.g. Gas is displaced from the displacement chamber into the expansion chamber along this throttle groove. The movement of the sliding door is determined by the acceleration applied by means of the energy accumulator (81) and by the delay caused simultaneously by the cylinder-piston unit (61). As soon as the piston (67) passes over the short longitudinal groove, the deceleration rate is further reduced. The sliding door moves slowly into its closed end position. There she stays without jerking.

Beim manuellen oder motorischen Öffnen der Schiebetür aus der geschlossenen Stellung zieht der Mitnehmer (90) das Mitnahmeelement (31) aus der Endposition entlang der Führungsfläche (22) in Richtung der Parkposition. Der Energiespeicher (81) wird geladen. Sobald das in der Öffnungsrichtung vordere Gleitelement (32) die Führungsnut (26) erreicht, kippt das Mitnahmeelement (31) unter der Wirkung der Feder (81) ab. Es liegt nun in einer kraft- und/oder formschlüssig verriegelten Parkposition. Beim weiteren Öffnen der Schiebetür löst sich das Mitnahmeelement (31) vom Mitnehmer (90). Das Mitnahmeelement (31) verbleibt in der Parkposition. Die Schiebetür kann nun weiter geöffnet werden.During manual or motorized opening of the sliding door from the closed position, the driver (90) pulls the entrainment element (31) out of the end position along the guide surface (22) in the direction of the parking position. The energy store (81) is loaded. As soon as the sliding element (32) in the opening direction reaches the guide groove (26), the driving element (31) tilts under the action of the spring (81). It is now in a locked and / or positively locked parking position. Upon further opening of the sliding door, the entrainment element (31) releases from the driver (90). The Carrier element (31) remains in the parking position. The sliding door can now be opened further.

Die Schiebetür kann eine weitere Einzugsvorrichtung (10) aufweisen, die an der in die Öffnungsrichtung zeigenden Seite der Schiebetür angeordnet ist. Bei einer derartigen Anordnung kann die Beschleunigungs- und Verzögerungsvorrichtung (20) zum gesteuerten Anfahren der geöffneten Endlage der Schiebetür eingesetzt werden.The sliding door may have another feed device (10) which is arranged on the side of the sliding door facing in the opening direction. In such an arrangement, the acceleration and deceleration device (20) can be used for the controlled approach of the open end position of the sliding door.
