Die Erfindung betrifft einen Türachließdämpfer, der am Türrahmen befestigt, mittels eines Bremszylinders ein zu schnelles TürenschlieBen und damit störende Geräusche verhindert.The invention relates to a door closing damper which is attached to the door frame and uses a brake cylinder to prevent the door from closing too quickly and thus prevent annoying noises.
Innerhalb des Zylinders wirkt ein Kolben derart, daß bei den letzten Zentimetern der Schließbewegung sich durch Kompression, dann duivn weichen übergang in Depression de* vor dem Kolben befindlichen Luft auf bestimmten Teilstrecken der Kolbenbewegung eine der SchlieQgeschwindigkeit analoge Dämpfung erfolgt.Der vorzugsweise im oberen Drehpunkt gegenüberliegende Winkel des Türrahmens befestigte Türschließdämpfer enthält mit dem Kolben verbunden einen Stößel, der bei geöffneter Tür durch eine Feder in Wirkctallung gebracht wird.A piston acts within the cylinder in such a way that during the last few centimeters of the closing movement, a damping analogous to the closing speed occurs over certain sections of the piston movement through compression and then a gentle transition into depression of the air in front of the piston. The door closing damper, which is preferably attached to the upper pivot point at the opposite angle of the door frame, contains a tappet connected to the piston which is activated by a spring when the door is opened.
Es sind Türschließdämpfer bekannt, bei denen wegen der Anpassung des Kolbenweges an die kreisförmige Bewegung der Tür gebogene Zylinder oder ausgleichende Gelenkanordnungen erforderlich sind. Außerdem sind in bekannten Geräten zur Erreichung der Dekompression einstellbare Ventile vorhanden. Vorgenannte Türschließdämpfer auch Türstoßdämpfer genannt, sind aufwendig in der Herstellung, erfordern einen gewissen Grad an Präzision und sind nicht waptungafrei.There are known door closing dampers that require curved cylinders or compensating joint arrangements to adapt the piston travel to the circular movement of the door. In addition, adjustable valves are present in known devices to achieve decompression. The aforementioned door closing dampers, also called door shock absorbers, are complex to manufacture, require a certain degree of precision and are not free of waptunga.
Er. sind auch TürschAießdämpfer bekannt, bei denen zur Dekompression der Luft Nuten an der Innenwand des Zylindera angebracht sind; wodurch die unter Druck gleitenden Dichtungen bald beschädigt sein können, vor allem bei heftigem Türschließen z. B. durch Wind.Door dampers are also known, in which grooves are fitted on the inner wall of the cylinder to decompress the air; as a result, the seals sliding under pressure can quickly become damaged, especially if the door is closed violently, e.g. due to wind.
Aufgabe der Erfindung ist die Beseitigen der vorgenannten Mängel, sowie eine wesentliche Vereinfachung und Verkleinerung der bekannten Geräte.The object of the invention is to eliminate the aforementioned deficiencies, as well as to significantly simplify and reduce the size of the known devices.
Bei der erfindungugemäßen Ausführung handelt es eich um einen geraden Zylinder (1), vorzugsweise aus einem gute Gleitei^anechaften aufweisenden Kunststoff, in dessen Boden zentrisch angeordnet ein durch das innere dea Kolbens (2) gleitender Bolzen (3) mit abgestuftem Durchmesser §Xüet den Meg der Kompression und Dekompression der vor dem Kolben (2) befindlichen Luft bewirkt. Entsprechend ist der mit dem Kolben (2) einstückig ausgebildete Stößel (4) rohrförmig und ein TeilstUck davon umschließt den Bolzen O) mit geringem Luftspalt (10) durch den die komprimierte Luft, entweichenThe embodiment according to the invention is a straight cylinder (1), preferably made of a plastic with good sliding properties, in the bottom of which a bolt (3) with a graduated diameter is arranged centrally and slides through the inside of the piston (2) to effect the degree of compression and decompression of the air in front of the piston (2). Accordingly, the tappet (4) which is formed in one piece with the piston (2) is tubular and a part of it encloses the bolt (10) with a small air gap (10) through which the compressed air can escape.
kann&lgr; Hlufbei ist wesentlich, daß der Kolben (2) im Zylinder (1) keine präzise Passung erfordert? da lh einer am Umfang des Kolbens ausgebildeten, in achsialer Richtung konischen Nute (5) sine Ö=Ring Dichtung (6) lose lagert&igr; die nur in Arbeitsrichtung ihre dichtende Aufgabe erfüllt» während sie beim öffnen der Tür Völlig frei mit dsm Kolben (2) durch eine leichte Feder (7) in Ausgangslage gebracht wird. Die konische Nute (5) ist etwa 2 &khgr; O-Ringstürke breit und ermöglicht ein leichtes Rollen des „ O-Ringes (6) vom kleinen zum größeren Durchmesser beim Türschließen und umgekehrt bei öffnen. Je heftiger die TUr geschlossen wird, umso stärker let die dämpfende Wirkung, während bei normalem Schließen der Dämpfer nicht wahrgenommen wird.It is important that the piston (2) in the cylinder (1) does not require a precise fit, since an O-ring seal (6) is loosely mounted in a groove (5) on the circumference of the piston that is conical in the axial direction, and only performs its sealing function in the working direction, while it is brought into its initial position completely freely with the piston (2) by a light spring (7) when the door is opened. The conical groove (5) is approximately 2 x O-ring thickness wide and allows the O-ring (6) to roll slightly from the small to the larger diameter when the door is closed and vice versa when it is opened. The harder the door is closed, the stronger the damping effect, while the damper is not noticeable when it is closed normally.
Der Kolbenetößel (4) wird in einem den Zylinder (1) abschließenden Ring (B) mit Spiel geführt, das ausreicht um den Stößel (4) der kreisförmigen üffnungs-und Schließbewegung der Tür anzupassen. Beim üffnen der Tür und Austreten des Stößels (4) bringt das konisch ausgebildete Übergangsstück (9) zwischen Kolben (2) und Stößel (4) in Endlage im als Gegenlager ebenfalls konisch geformten Ring (6) den Stößel (4) wieder in achaiale Ausgangsposition. Vom besonderen Vorteil iet dadurch der Wegfall von rechts und links ausgebildeten Türschließdämpfern für rechts oder links öffnende Türen.The piston tappet (4) is guided in a ring (B) that closes the cylinder (1) with enough play to adapt the tappet (4) to the circular opening and closing movement of the door. When the door is opened and the tappet (4) comes out, the conical transition piece (9) between the piston (2) and tappet (4) in the end position in the ring (6), which is also conical and serves as a counter bearing, brings the tappet (4) back to its axial starting position. This has the particular advantage of eliminating the need for right and left door closing dampers for doors that open to the right or left.
Gleitet beim Türschließen Kolben (2) / Stößel (4) Über den Bolzen (J) dann entweicht über den Luftspalt (10) auf der Strecke des zylindrischen Teils am Bolzen (3) nur eine geringe Menge der komprimierten Luft nach hinten. Erst bei Erreichen der konischen Verringerung des Durchmessers am Bolzen (3) entweicht zunehmend mehr Luft, wodurch ein weicher übergang von Dämpfung zum normalen Schließen der Tür bewirkt wird.When the door is closed, if the piston (2) / tappet (4) slides over the bolt (J), then only a small amount of the compressed air escapes backwards through the air gap (10) along the path of the cylindrical part on the bolt (3). Only when the conical reduction in diameter on the bolt (3) is reached does more and more air escape, which creates a smooth transition from damping to normal closing of the door.
