Abstract
Description
Die Erfindung bezieht sich auf einen Fluiddämpfer, insbesondere für bewegliche Möbelteile mit einem Zylinder und einem darin linear verfahrbaren Kolben, der mindestens eine Durchlassöffnung für ein im Zylinder vorgesehenes Dämpfungsfluid aufweist, und mit mindestens einer bewegbaren Ringscheibe im Bereich der Durchlassöffnung(en) sowie einer Feder die den Kolben nach erfolgter Dämpfung wieder in die Funktionsstellung bewegt.The The invention relates to a fluid damper, in particular for movable furniture components with a cylinder and a linearly movable piston therein, the at least one passage opening for a Cylinder provided damping fluid has, and with at least one movable annular disc in the area the passage opening (s) and a spring which returns the piston after damping moved to the functional position.
Derartige Fluiddämpfer werden verwendet, um insbesondere die Schließbewegung von beweglichen Möbelteilen, wie Möbeltüren, Klappen oder Schubladen, im hintersten Schließbereich zu dämpfen.such fluid damper are used, in particular, for the closing movement of movable furniture parts, like furniture doors, flaps or drawers to dampen in the rearmost closing area.
Nach dem bekannten Stand der Technik wird der Zylinder vorzugsweise am Möbelkorpus beispielsweise einer Möbelseitenwand oder einem Möbelboden befestigt und die Möbeltüre oder die Frontblende einer Schublade stößt beim Schließen an der Kolbenstange des Kolbens an. Durch den Strömungswiderstand des Dämpfungsfluids beim Verschieben des Kolbens entsteht die Dämpfung. Als Dämpfungsfluid wird vorzugsweise eine Hydraulikflüssigkeit, beispielsweise ein Öl (Silikonöl), eingesetzt. Es können aber auch Gase, insbesondere Luft, zur Anwendung kommen.To the known prior art, the cylinder is preferably on furniture body for example, a furniture sidewall or a furniture floor attached and the furniture door or the front panel of a drawer abuts the piston rod when closing of the piston. By the flow resistance of the damping fluid when moving the piston creates the damping. As damping fluid For example, a hydraulic fluid, for example an oil (silicone oil), is used. It can but also gases, in particular air, are used.
Die
Aufgabe der Erfindung ist es, einen Fluiddämpfer der eingangs erwähnten Art dahingehend zu verbessern, dass einerseits seine Dämpfwirkung besser der Geschwindigkeit des bewegten Möbelteiles angepasst wird und es andererseits aber nicht zur vollständigen Blockade des Kolbens im Zylinder kommen kann.task The invention is a fluid damper of the type mentioned to improve so that on the one hand its damping effect better the speed of the moving furniture part is adjusted and but on the other hand not to complete blockage of the piston can come in the cylinder.
Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass die mindestens eine Ringscheibe derart angeordnet ist, dass sie beim Dämpfungshub des Kolbens die Durchlassöffnungen) des Kolbens zumindest teilweise abdeckt und dass ein Ringspalt zwischen dem Kolben und einer Gehäuseinnenwand des Zylinders besteht.The inventive task is solved by that the at least one annular disc is arranged such that she at the damping stroke of Piston the passage openings) the piston at least partially covers and that an annular gap between the piston and a housing inner wall of the Cylinder exists.
Ein Ausführungsbeispiel der Erfindung sieht vor, dass die Ringscheibe(n) beim Dämpfungshub elastisch verbiegbar ist bzw. sind.One embodiment The invention provides that the annular disc (s) during the damping stroke elastic is bendable or are.
Vorteilhaft ist vorgesehen, dass die Ringscheiben unterschiedliche Steifigkeit aufweisen, was beispielsweise dadurch erreicht wird, dass die Ringscheiben unterschiedliche Dicke aufweisen oder aus unterschiedlichem Material gefertigt sind.Advantageous It is envisaged that the annular discs have different rigidity have, for example, achieved by the fact that the annular discs have different thickness or made of different material are made.
Ein weiteres Ausführungsbeispiel der Erfindung sieht vor, dass der Kolben mit einem Stift versehen ist, auf dem die Ringscheiben axial verschieblich gelagert sind, wobei Federn vorgesehen sind, die in der Ruhestellung des Kolbens die Ringscheiben vom Kolben und voneinander distanzieren.One another embodiment The invention provides that the piston is provided with a pin is, on which the annular discs are mounted axially displaceable, wherein springs are provided, which in the rest position of the piston distance the washers from the piston and from each other.
Vorzugsweise sind drei oder vier elastisch bewegbare Ringscheiben vorgesehen.Preferably three or four elastically movable annular discs are provided.
Beim Einschieben der Kolbenstange strömt die Hydraulikflüssigkeit durch die Ringspalte zwischen den Ringscheiben und der Zylinderwand und durch die Durchlassöffnungen im Kolben. Je nach der Geschwindigkeit des bewegten Möbelteiles und somit des Kolbens werden die elastisch verbiegbaren Ringscheiben durch den Strömungswiderstand zurückgebogen oder es werden die Federn zwischen den Ringscheiben zusammengedrückt.At the Pushing the piston rod flows hydraulic fluid through the annular gaps between the annular discs and the cylinder wall and through the passage openings in the piston. Depending on the speed of the moving furniture part and thus the piston become the elastically bendable annular discs through the flow resistance recurved or the springs are compressed between the washers.
Je höher derart entstehende Strömungswiderstand ist, umso kleiner wird der wirksame Durchflussquerschnitt der Durchlassöffnungen, da die jeweils vordere Ringscheibe die Durchlassöffnungen der dahinter befindlichen Ringschale zum Teil oder zur Gänze abdeckt. Die Geschwindigkeit des Kolbens verringert sich dementsprechend.ever higher like this resulting flow resistance is, the smaller is the effective flow area of the passage openings, since the respective front annular disc the passage openings of the behind it Ring shell partly or wholly covers. The speed of the piston decreases accordingly.
Wird der Kolben langsamer, wird auch der Strömungswiderstand niedriger und die Ringscheiben bewegen sich wieder in ihre Ausgangsstellung, wodurch der wirksame Querschnitt der Durchlassöffnungen vergrößert wird.Becomes the piston slower, the flow resistance is also lower and the annular discs move back to their original position, whereby the effective cross section of the passage openings is increased.
