KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft die bekannten Türschließer mit schräger Stützstange und besteht darin, daß die Stützstange t nicht wie üblich die Tür anhebt, sondern die federbelastete Kolbenstange einer parallel zur Tür-' drehachse stehenden Flüssigkeitsbremse bekannter Art verschiebt und somit deren Feder spannt, wenn die Tür geöffnet wird, während umgekehrt die Federspannung durch die ίο Stützstange auf Schluß der Tür wirkt.The present invention relates to the known door closer with an inclined support rod and consists in the fact that the support rod t does not lift the door as usual, but moves the spring-loaded piston rod of a known type of fluid brake parallel to the door's axis of rotation and thus tensions its spring when the door is opened is, while vice versa the spring tension acts through the ίο support rod on closing the door.
An der Tür α ist ein vorspringender Arm b mittels Schrauben oder in irgend welcher Weise befestigt, in dem parallel zur Türdrehachsc ein Bolzen c gelagert ist, welch letztcrcr an dem einen Ende eine Schraubenmutter d trägt, während das andere Ende in ein Gelenk e ausläuft.A protruding arm b is fastened to the door α by means of screws or in some way, in which a bolt c is mounted parallel to the door rotation axisc, the latter bearing a screw nut d at one end, while the other end terminates in a hinge e .
An der Tür bezw. neben der letzteren befindet sich der parallel zur Türdrehachse an-20· gebrachte Bremszylinder g, dessen Oberkante sich über dem Arm b befindet.At the door resp. next to the latter is the brake cylinder g, which is attached parallel to the door axis of rotation and whose upper edge is located above the arm b .
Die bekannte Stützstange t stützt sich einerseits auf b, indem sie mit dem Bolzen c durch Gelenk e verbunden ist, und ist andereres'scits mit dem obersten, über den Zylinder hinausragenden Ende der Kolbenstange h durch einen Ring 5 verbunden, der am oberen Ende der Stützstange i> angelenkt ist. Die Kolbenstange trägt an ihrem unteren Ende einen Brcmskolbcn k von bekannter Einrichtung, der in ebenfalls bekannter Weise unter der Einwirkung einer Schraubenfeder ρ steht. Das Innere des Zylinders ist mit Glyzerin gefüllt und der Türschließer- wirkt beim Schließen der Tür wie folgt: .The known support rod t is based on the one hand on b by being connected to the bolt c by joint e , and on the other hand it is connected to the uppermost end of the piston rod h protruding beyond the cylinder by a ring 5 which is attached to the upper end of the Support rod i> is articulated. The piston rod carries at its lower end a brake piston k of a known device, which is also known to be under the action of a helical spring ρ . The inside of the cylinder is filled with glycerine and the door closer works as follows when the door is closed:.
Beim Öffnen der Tür stellt sich in der bekannten Weise die Stützstangc t steiler, so daß der Ring s sich hebt und die Kolbenstange h aus dem Zylinder g emporzieht. Hierdurch wird die Feder ρ gespannt und das Glyzerin tritt in bekannter Weise durch öffnungen im Kolben unter diesen, ohne Bremsung zu verursachen. Läßt man die geöffnete Tür los, so wird die Stützstange durch die Feder wieder schräger gestellt und dadurch die Tür geschlossen, wobei in bekannter Weise die Flüssigkeit, der der Rückweg durch die Kolbenöffnungen verschlossen ist, bremsend auf den Kolben Ic und somit auch auf die Tür einwirkt. .When the door is opened, the support rod t becomes steeper in the known manner, so that the ring s rises and the piston rod h pulls up out of the cylinder g. As a result, the spring ρ is tensioned and the glycerine passes in a known manner through openings in the piston underneath them without causing braking. If you let go of the open door, the support rod is tilted again by the spring and thereby the door is closed, the liquid, which is closed on the return path through the piston openings, braking on the piston Ic and thus also on the door acts. .
Das Glyzerin kann hierbei nicht durch die öffnungen η des Kolbens ijk in den Raum oberhalb des Kolbens zurücktreten, weil diese Öffnungen durch biegsame Scheiben geschlossen werden. Das Glyzerin wird somit gezwungen,- durch die öffnung y in der Überwurfmutter und durch die Öffnung ν im unteren Abschluß u hindurchzutreten, von wo aus es in die hohle Kolbenstange gelangt und durch die öffnungen ο in den Raum über dem Kolben zurückgeführt wird.The glycerine cannot withdraw through the openings η of the piston ijk into the space above the piston because these openings are closed by flexible disks. The glycerine is thus forced to - pass through the opening y in the union nut and through the opening ν in the lower end u , from where it enters the hollow piston rod and is returned through the openings ο into the space above the piston.
