Beim Weiterbewegen der Tür oder Schublade wird in der Parkposition (11) des Mitnahmeelements (71) die Kupplung zwischen dem Mitnehmer (5) und der Beschleunigungs- und Verzögerungsvorrichtung (10) gelöst. Die Beschleunigungs- und Verzögerungsvorrichtung (10) verbleibt in der Parkposition (11), bis bei einer erneuten Bewegung der Tür oder Schublade in Richtung der Endlage der Mitnehmer (5) mit dem Mitnahmeelement (71) koppelt.During manual or motorized movement of the door or the drawer out of the end position, the carrier element (71) of the acceleration and deceleration device (10) is moved out of the end position (12) in the direction of the parking position (11). In this case, the energy store (121) is loaded again. As the door or drawer is moved further, the coupling between the driver (5) and the acceleration and deceleration device (10) is released in the parking position (11) of the carrier element (71). The acceleration and deceleration device (10) remains in the parked position (11) until, when the door or drawer moves again in the direction of the end position, the driver (5) is coupled to the carrier element (71).
Es ist auch denkbar, die Beschleunigungs- und Verzögerungsvorrichtung (10) am Möbelkorpus (3) und den Mitnehmer (5) an einer Tür oder an einer Schublade anzuordnen.It is also conceivable to arrange the acceleration and deceleration device (10) on the furniture body (3) and the driver (5) on a door or on a drawer.

Die
Die Trag- und Führungsvorrichtung (30) umfasst ein zweiteiliges Gehäuse (31) mit einander spiegelbildlich angeordneten Gehäuseteilen (32). Das Gehäuse (31) umfasst einen Aufnahmebereich (33) sowie einen Führungsbereich (34). Im Aufnahmebereich (33) ist die Zylinder-Kolben-Einheit (41) mittels zweier am Zylinderkopfteil (42) eingreifender Nasen (35) gehalten. Der Führungsbereich (34) umfasst beispielsweise zwei einander gegenüber angeordnete Führungsbahnen (37). Im Ausführungsbeispiel sind diese Führungsbahnen (37) eingesenkte Nuten, die jeweils einen parallel zu den Hubrichtungen (55) des Kolbens (45) und der Kolbenstange (44) der Zylinder-Kolben-Einheit (41) orientierten Abschnitt (38) und einen an diesen angrenzenden einen Viertelkreis bildenden gebogenen Abschnitt (39) umfassen.

Die Zylinder-Kolben-Einheit (41) umfasst einen Zylinder (46), in dem ein Kolben (45) geführt ist.The cylinder-piston unit (41) comprises a cylinder (46) in which a piston (45) is guided.
Der Zylinder (46) umfasst einen Zylindermantel (47) mit einem Kopfteil (42) und einen in den Zylindermantel (47) eingesetzten Zylinderboden (43). Der Zylindermantel (47) und der Zylinderboden (43) sind beispielsweise als Spritzgussteile aus thermoplastischem Kunststoff, z.B. Polyoximethylen, hergestellt. Der Zylindermantel (47) ist hier auf seiner Außenseite zylindrisch und hat im Zylinderkopfbereich eine Einschnürung (48). Seine Länge beträgt beispielsweise das Neunfache des Außendurchmessers. Die nichtzylindrische Zylinderinnenwandung (51) ist beispielsweise zur Entformung z.B. in Form eines Kegelstumpfmantels ausgebildet. Die kleinere Querschnittsfläche dieses Kegelstumpfmantels befindet sich am Kopfteil (42) des Zylinders (46), die größere Querschnittsfläche am Zylinderboden (43). Die Steigung dieses Kegels beträgt beispielsweise 1:140. Die Innenwandung (51) ist gegebenenfalls poliert.The cylinder (46) comprises a cylinder jacket (47) with a head part (42) and a cylinder bottom (43) inserted into the cylinder jacket (47). The cylinder jacket (47) and the cylinder bottom (43) are, for example, injection molded parts made of thermoplastic material, e.g. Polyoxymethylene, produced. The cylinder jacket (47) is here cylindrical on its outer side and has a constriction (48) in the cylinder head area. Its length is for example nine times the outer diameter. The non-cylindrical cylinder inner wall (51) is, for example, for demolding, e.g. formed in the shape of a truncated cone.

Zum Einsetzen des Zylinderbodens (43) verfügt das Bodenende (49) z.B. über eine zweistufige rotationssymmetrische Einkerbung (56). Bei der Montage des Zylinderbodens (43) wird die Luft aus dem Bereich der äußeren Einkerbung nach außen verdrängt, während die Luft aus der inneren Einkerbung in den Zylinderinnenraum (54) verdrängt wird. Auch andere Ausführungsformen einer hermetischen Abdichtung sind denkbar.For insertion of the cylinder bottom (43) has the bottom end (49), for example via a two-stage rotationally symmetrical Notch (56). During assembly of the cylinder bottom (43), the air is displaced out of the region of the outer notch to the outside, while the air from the inner notch in the cylinder interior (54) is displaced. Other embodiments of a hermetic seal are conceivable.

Nach dem Prinzip der Selbsthilfe wird unmittelbar mit dem Beginn der Einfahrbewegung der Kolbenstange (44) der Dichtkragen (63) unter Verformung an die Zylinderinnenwandung (51) angepresst. Der Verdrängungsraum (65) wird quasi hermetisch vom Ausgleichsraum (66) getrennt. Beim weiteren Verfahren der Kolbenstange (44) in Richtung des Zylinderbodens (43) wird das Volumen des Verdrängungsraums (65) verkleinert. Der Gasdruck, z.B. der Luftdruck im Verdrängungsraum (65), erhöht sich und wirkt als interne Kraft auf das Kolbendichtelement (61) und auf die Bremsmanschette (62). Außerdem dichtet im Ausführungsbeispiel die Kolbenstangendichtung (58) zumindest in einem Teilbereich des Kolbenstangenhubs den Ausgleichsraum (66) gegen die Umgebung (1) ab, wodurch im Ausgleichsraum (66) ein Unterdruck erzeugt wird. Die Geschwindigkeit der Schublade oder Tür wird stark abgebremst.In the acceleration and deceleration device (10), the driving element (71) acts on the piston rod (44) and on the Piston (45) of the cylinder-piston unit (41). According to the principle of self-help, the sealing collar (63) is pressed against the cylinder inner wall (51) with deformation immediately at the beginning of the retraction movement of the piston rod (44). The displacement chamber (65) is virtually hermetically separated from the compensation chamber (66). During further movement of the piston rod (44) in the direction of the cylinder bottom (43), the volume of the displacement chamber (65) is reduced. The gas pressure, eg the air pressure in the displacement chamber (65), increases and acts as an internal force on the piston sealing element (61) and on the brake sleeve (62). In addition, seals in the embodiment, the piston rod seal (58) at least in a portion of the piston rod stroke the compensation chamber (66) from the environment (1), whereby a vacuum is generated in the expansion chamber (66). The speed of the drawer or door is greatly slowed down.
Mit zunehmendem Hub der Kolbenstange (44) erreicht der Dichtkragen (63) des Kolbendichtelements (61) den Beginn der Längsnut (52). Sobald, wie in der

Die Kolbenstange (44) der Beschleunigungs- und Verzögerungsvorrichtung (10) wird weiter eingefahren. Sobald sich das Kolbendichtelement (61) vollständig von der Innenwandung (51) gelöst hat, strömt zusätzlich Luft aus dem Verdrängungsraum (65) in den Ausgleichsraum (66). Das Kolbendichtelement (61) nimmt wieder seine Ausgangslage vor dem Beginn der Hubbewegung an. Die nunmehr fast zugezogene Schublade oder Tür hat jetzt eine geringe Restgeschwindigkeit.The piston rod (44) of the acceleration and deceleration device (10) is retracted further. As soon as that Piston sealing element (61) has completely detached from the inner wall (51), additional air flows from the displacement chamber (65) in the compensation chamber (66). The piston sealing element (61) resumes its initial position before the start of the lifting movement. The now almost closed drawer or door now has a low residual speed.

Die Beschleunigungs- und Verzögerungsvorrichtung (10) kann beim Schließen und/oder beim Öffnen einer Schublade oder Tür eingesetzt werden.The acceleration and deceleration device (10) can be used when closing and / or opening a drawer or door.
Die Beschleunigungs- und Verzögerungsvorrichtung (10) kann derart aufgebaut sein, dass der Verdrängungsraum (65) der Zylinder-Kolben-Einheit (41) kolbenstangenseitig angeordnet ist. Die Parkposition (11) des Mitnahmeelements (71) ist dann der Verzögerungsvorrichtung (40) zugewandt.The acceleration and deceleration device (10) may be constructed such that the displacement space (65) of the cylinder-piston unit (41) is arranged on the piston rod side. The parking position (11) of the carrier element (71) then faces the delay device (40).

Beim Öffnen der Mitteltür (6) nach rechts, vgl.
Die zweite Zug- und Abbremsvorrichtung (210) wird zusammen mit der Mitteltür (6) verschoben. Hierbei kontaktiert das Zugteil (304) der zweiten Vorrichtung (210) mit seiner Zugfläche (305) die Schubfläche (95) der ersten Vorrichtung (10). Das zweite Mitnahmeelement (271) wird aus der Endlage (212) in Richtung der Parkposition (211) gezogen. Hierbei wird mittels der Kolbenstange (244) der Kolben (245) der Zylinder-Kolben-Einheit (241) ausgefahren. Gleichzeitig wird die Zugfeder (321) gespannt, der Energiespeicher (321) wird geladen.The second pulling and braking device (210) is displaced together with the center door (6). In this case, the pulling part (304) of the second device (210) contacts the pushing surface (95) of the first device (10) with its traction surface (305). The second driving element (271) is pulled out of the end position (212) in the direction of the parking position (211). In this case, the piston (245) of the cylinder-piston unit (241) is extended by means of the piston rod (244). At the same time, the tension spring (321) is tensioned, the energy store (321) is charged.
Auch beim weiteren Öffnen der Mitteltür (6) in der Öffnungsrichtung (142) verbleibt das Mitnahmeelement (71) der ersten Vorrichtung (10) in der Endlage (12), vgl.
Die Zugfläche (305) des zweiten Mitnahmeelements (271) hat beim Kippen des Sicherungsteils (301) in die Parkposition (211) die Schubfläche (95) des Führungsteils (81) ersten Mitnahmeelements (71) verlassen. Die Flächen (305, 95) sind nun voneinander getrennt. Das Zugteil (304) der zweiten Vorrichtung (210) kann das Schubteil (94) der ersten Vorrichtung (10) passieren. Die Mitteltür (6) kann nun quasi widerstandsfrei weiter in der Öffnungsrichtung (142) geöffnet werden.The traction surface (305) of the second entrainment element (271) has left the thrust surface (95) of the guide part (81) of the first entrainment element (71) when tilting the securing part (301) into the parking position (211). The surfaces (305, 95) are now separated. The tensile part (304) of the second Device (210) can pass the pushing part (94) of the first device (10). The center door (6) can now be opened almost without resistance further in the opening direction (142).
Das Schließen der nach rechts geöffneten Mitteltür (6) erfolgt in der umgekehrten Reihenfolge. Die Ausgangslage zeigt die
Beim z.B. zunächst manuellen Zuschieben der Mitteltür (6) in der Zuziehrichtung (145) stößt die Schubfläche (295) der zweiten Vorrichtung (210) an die Zugfläche (105) der ersten Vorrichtung (10), vgl.

Sollte die Mitteltür (6) kräftig zugeschoben worden sein, kann mit dem Auslösen des zweiten Mitnahmeelements (271) aus der Parkposition (211) auch das erste Mitnahmeelement (71) aus der Endposition (12) herausgezogen werden. Bei dieser Überlastsicherung wird der Energiespeicher (121) der ersten Vorrichtung (10) teilweise geladen, wodurch die Mitteltür (6) zusätzlich abgebremst wird. Danach entspannt sich der erste Energiespeicher (121) wieder. Die Mitteltür (6) hat jetzt nur noch eine geringe Geschwindigkeit oder sie ist sogar stehen geblieben. Das weitere Verfahren der Tür (6) erfolgt wie oben beschrieben.If the center door (6) has been pushed vigorously, the first entrainment element (71) can also be pulled out of the end position (12) when the second entrainment element (271) is released from the parking position (211). In this overload protection of the energy storage device (121) of the first device (10) is partially charged, whereby the center door (6) is additionally braked. After that, the first energy store (121) relaxes again. The center door (6) has now only a low speed or it has even stopped. The further procedure of the door (6) takes place as described above.
Sobald das zweite Mitnahmeelement (271) seine Endposition (212) erreicht hat, kann die Mitteltür (6) aufgrund ihrer Massenträgheit noch innerhalb des in der Hubrichtung (55) orientierten Spiels der beiden Mitnahmeelemente (71, 271) auspendeln. Beispielsweise lösen sich beide Kontaktpaarungen (25, 26). Die zugezogene Mitteltür (6) nimmt nun wieder ihre Ausgangslage ein.As soon as the second entrainment element (271) has reached its end position (212), the center door (6) due to its inertia can still oscillate within the clearance of the two entrainment elements (71, 271) oriented in the stroke direction (55). For example, both contact pairs (25, 26) are released. The drawn middle door (6) now returns to its original position.

Mit dem Auslösen des Mitnahmeelements (71) aus der Parkposition (11) entspannt sich die Zugfeder (121) der ersten Vorrichtung (10). Sie zieht das Mitnahmeelement (71) in Richtung der Endlage (12). Die Kontaktpaarung (26) wird entlastet oder gelöst. Das Mitnahmeelement (71) der ersten Vorrichtung (20) wird weiter eingefahren, bis seine Zugfläche (105) die Schubfläche (295) des zweiten Mitnahmeelements (271) kontaktiert. Das Anschlagteil (104) des ersten Sicherungsteils (101) legt sich an das Anschlagteil (294) des zweiten Führungsteils (281), eine Kontaktpaarung (25) bildend, an. Die Mitteltür (6) wird weiter in der Zuziehrichtung (144) zugezogen.With the triggering of the driving element (71) from the parking position (11), the tension spring (121) of the first device (10) relaxes. It pulls the driving element (71) in the direction of the end position (12). The contact pairing (26) is relieved or released. The entrainment element (71) of the first device (20) is retracted until its traction surface (105) contacts the thrust surface (295) of the second entrainment element (271). The abutment part (104) of the first securing part (101) bears against the abutment part (294) of the second guide part (281), forming a contact pairing (25). The center door (6) is pulled further in the closing direction (144).
Mittels der ersten Zugfeder (121) wird das erste Mitnahmeelement (71) in die Endlage (12) gezogen. Der Kolben (45) wird eingefahren. Das Massenträgheitsmoment der Mitteltür (6) kann nun die Kontaktpaarung (25) der Zugfläche (105) des ersten Mitnahmeelements (71) und der Schubfläche (295) des zweiten Mitnahmeelements (271) lösen.

Die beiden Zug- und Abbremsvorrichtungen (10; 210) können auch so angeordnet sein, dass die Zylinder-Kolben-Einheiten (41; 241) nach links zeigen. Der Bewegungsablauf ist dann analog zum oben beschriebenen Ablauf.The two pulling and braking devices (10, 210) can also be arranged so that the cylinder-piston units (41, 241) point to the left. The sequence of movements is then analogous to the procedure described above.
Das Zug- und Abbremsvorrichtungspaar (21) kann zwei unterschiedliche Zug- und Abbremsvorrichtungen (10; 210) aufweisen. Diese können beispielsweise unterschiedlichen Hub und/oder unterschiedlichen Querschnitt haben. Hierbei kann das Geschwindigkeitsprofil über den Hub beim Schließen von rechts anders sein als Geschwindigkeitsprofil über den Hub beim Schließen von links.The train and deceleration device pair (21) may have two different traction and deceleration devices (10; 210). These may for example have different stroke and / or different cross section. In this case, the speed profile over the stroke when closing from the right can be different than the speed profile over the hub when closing from the left.
Eine oder beide Zug- und Abbremsvorrichtungen (10; 210) kann auch derart aufgebaut sein, dass ihr Verdrängungsraum zwischen dem Kolben und dem Zylinderkopf der Zylinder-Kolben-Einheit angeordnet ist. Bei einer derartigen Vorrichtung ist in der Parkstellung die Kolbenstange eingefahren und in der Endstellung ausgefahren. Die Definitionen der Zug- und der Schubfläche entsprechen der oben genannten Definition.One or both of the pulling and braking devices (10, 210) can also be constructed such that their displacement space is arranged between the piston and the cylinder head of the cylinder-piston unit. In such a device, the piston rod is retracted in the parking position and extended in the end position. The definitions of the tensile and shear surfaces correspond to the above definition.
Im Ausführungsbeispiel haben die Zug- und Abbremsvorrichtungen (10; 210) pneumatische Verzögerungsvorrichtungen. Es ist aber auch denkbar, pneumatische Dämpfer, deren Verdrängungsraum mit der Umgebung (1) kommuniziert, einzusetzen. Auch der Einsatz hydraulischer Dämpfer ist denkbar. Bei den letztgenannten Dämpfern kann die Kolbenstange federbelastet ausfahrbar sein und mit einer Anstoßfläche am Mitnahmeelement anliegen.In the exemplary embodiment, the pulling and braking devices (10, 210) have pneumatic retarding devices. However, it is also conceivable to use pneumatic dampers whose displacement space communicates with the environment (1). The use of hydraulic dampers is conceivable. In the latter dampers, the piston rod may be spring-loaded extendable and abut with an abutment surface on the driving element.
Auch Kombinationen der einzelnen Ausführungsbeispiele sind denkbar.Combinations of the individual embodiments are conceivable.
