Abstract
Description
Die Erfindung betrifft einen Türschließer nach dem Oberbegriff des Anspruchs 1.The invention relates to a door closer according to the preamble of
Die
Die Anordnung ist aufgrund vieler Bauteile und Dichtstellen aufwändig und möglicherweise störungsanfällig. Die Dämpfung der Schließgeschwindigkeit ist nur in zwei Stufen möglich, wobei lediglich der Umstellpunkt einstellbar ist. Eine Öffnungsdämpfung ist nicht vorhanden.The arrangement is complex due to many components and sealing points and may be prone to failure. The damping of the closing speed is possible only in two stages, with only the Umstellpunkt is adjustable. An opening damping is not available.
Aus der
Nachteilig ist der Einsatzpunkt der Öffnungsdämpfung in Bezug auf den Türöffnungswinkel durch die Position des Ventils im Strömungskanal festgelegt.Disadvantageously, the starting point of the opening damping with respect to the door opening angle is determined by the position of the valve in the flow channel.
Der Erfindung liegt die Aufgabe zugrunde, einen Türschließer auszubilden, dessen Einsatzpunkt für die Öffnungsdämpfung einstellbar ist.The invention has for its object to form a door closer, the point of use for the opening loss is adjustable.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of
Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.
Die Öffnungsdämpfung verhindert durch Dämpfen der Türbewegung, dass der Flügel der Tür bei einem unachtsamen Öffnen beispielsweise an einer Wand, einem Möbelstück oder ähnlichem anschlägt, wodurch eine Beschädigung sowohl des Türflügels als auch der Wand bzw. des Möbelstücks verhindert wird. Abhängig vom möglichen maximalen Türöffnungswinkel ist vorteilhaft der Einsatzpunkt der Öffnungsdämpfung einstellbar, um ein möglichst weiten Bereich der Türöffnung den Türflügel ungedämpft öffnen zu können.The dampening of the door prevents the door from slamming against, for example, a wall, a piece of furniture or the like, thereby preventing damage to both the door panel and the wall or furniture. Depending on the possible maximum door opening angle, the point of application of the opening damping is advantageously adjustable in order to be able to open the door leaf undamped over the widest possible range of the door opening.
Die Position des Kolbens des Türschließers steht in direktem Zusammenhang mit der Öffnungswinkel der Tür, da die Abtriebswelle des Türschließers über eine Getriebeanordnung, beispielsweise mit einer Kurvenscheibe oder einem Zahntrieb, mit dem Kolben verbunden ist, wobei die Drehbewegung der Abtriebswelle der Getriebeanordnung in eine Verschiebebewegung des Kolbens umgesetzt wird, und umgekehrt.The position of the piston of the door closer is directly related to the opening angle of the door, since the output shaft of the door closer via a gear assembly, for example with a cam or a pinion, is connected to the piston, wherein the rotational movement of the output shaft of the gear assembly in a sliding movement of the Piston is reacted, and vice versa.
Der Türschließer weist zur Einstellung des Einsatzpunkts der Öffnungsdämpfung ein Schaltventil auf, das einen Magneten umfasst, der in einer Aussparung im Gehäuse verstellbar aufgenommen ist und der auf eine Ventilkugel in einen Überströmkanal im Kolben des Türschließers einwirkt, wobei in dem Überströmkanal ein der Ventilkugel zugeordneter Ventilsitz angeordnet ist. Die Position des Magneten in Bezug auf den Kolben bestimmt den Einsatzpunkt der Öffnungsdämpfung, in welchem die Ventilkugel auf deren zugeordnetem Ventilsitz aufliegt und den Überströmkanal im Kolben verschließt.The door closer has to adjust the point of application of the opening damping on a switching valve which comprises a magnet which is adjustably received in a recess in the housing and acting on a valve ball in an overflow channel in the piston of the door closer, wherein in the overflow one of the valve ball associated valve seat is arranged. The position of the magnet with respect to the piston determines the point of application of the opening damping, in which the valve ball rests on its associated valve seat and closes the overflow channel in the piston.
Das Schaltventil bewirkt ein Öffnen bzw. Schließen des Überströmkanals. Bei verschlossenem Überströmkanal kann bei einer Bewegung des Kolbens in Öffnungsrichtung die Hydraulikflüssigkeit im Türschließer nur über ein im Gehäuse des Türschließers angeordnetes, von außen einstellbares Drosselventil für die Öffnungsdämpfung strömen.The switching valve causes an opening or closing of the overflow. When the overflow channel is closed, the hydraulic fluid in the door closer can flow only in the case of a movement of the piston in the opening direction via an externally adjustable throttle valve for the opening damping arranged in the housing of the door closer.
Die Position des Magneten ist in Bezug auf den Kolben bzw. auf die Ventilelemente Ventilkugel und Ventilsitz im Kolben einstellbar, wozu beispielsweise eine hier nicht dargestellt Klemmeinrichtung vorgesehen sein kann, die ein stufenloses Verschieben und Festlegen des Magneten längs der Aussparung im Gehäuse ermöglicht.The position of the magnet is adjustable with respect to the piston or valve elements on the valve ball and valve seat in the piston, including, for example, a clamping device, not shown here may be provided which allows a continuous displacement and fixing of the magnet along the recess in the housing.
