Description

Die Türbremse hat den Zweck, das Zuschlagen von Türen zu verhindern, gleichgültig, ob die Tür mit einer Selbstschließvorrichtung (ohne Bremse) versehen ist oder nicht. Sie hat gegenüber den bisher verwendeten Türbremsen den Vorteil besonderer Einfachheit.The purpose of the door brake is to prevent doors from slamming, no matter whether the door is equipped with a self-closing device (without brake) or not. she has compared to the previously used door brakes the advantage of particular simplicity.

Die Erfindung besteht im wesentlichen aus einer Bremsstange s, welche bei a am Türstock, in entsprechender Entfernung von derThe invention consists essentially of a brake rod s, which at a on the door frame, at a corresponding distance from the

ίο Angel, gelenkig befestigt ist, und einem Fassonstück m, welches bei b, ebenfalls gelenkig, an der Tür selbst montiert ist. Dieser Teil m ist derart ausgedreht, daß der zylindrische Hohlraum bei k konisch verläuft, während er bei p durch eine ebene Platte abgeschlossen ist. In diesem Hohlraum befindet .sich eine in sich geschlossene Spiralfeder e, welche die Bremsstange mit leichtem Druck umspannt. Wird nun die Tür geöffnet (Abb. 1), so legt sich die Spirale e an die ebene Platte p und rollt über so die Bremsstange s; die Tür kann also ohne Widerstand geöffnet werden. Schließt man die Tür, wird die Spirale e in den Konus- k eingezogen, zusammengedrückt, an die Stange s festgepreßt, und die Tür ist nur mit Überwindung eines gewissen Widerstandes zu schließen. Abb. 2 zeigt die Tür geschlossen und die Spirale e in den Konus k eingezogen. ίο hinge, is articulated, and a Fassonstück m, which at b, also articulated, is mounted on the door itself. This part m is turned out in such a way that the cylindrical cavity is conical at k , while it is closed off at p by a flat plate. In this cavity there is a self-contained spiral spring e, which spans the brake rod with light pressure. If the door is now opened (Fig. 1), the spiral e lies against the flat plate p and thus rolls over the brake rod s; the door can therefore be opened without resistance. If we exclude the door, the spiral e k is retracted into the cone, compressed to the pole s clinched, and the door is to close only overcoming a certain resistance. Fig. 2 shows the door closed and the spiral e drawn into the cone k .

Die Stärke der Bremswirkung kann durch den Winkel des Konus k und die Drahtstärke der Spirale 5 bestimmt werden.The strength of the braking effect can be determined by the angle of the cone k and the wire thickness of the spiral 5.

In vielen Fällen wird es von Vorteil sein, nur einen Teil des Weges beim Schließen der Tür zu bremsen. Dies wird durch eine entsprechende, stellenweise Abschwächung der Bremsstange erreicht.In many cases it will be beneficial to only close part of the way when closing the Brake door. This is achieved through a corresponding weakening of the Brake rod reached.
