Description
Schiebefenster für :Fahrzeuge,- - insbesondere Eisenbahnwagen, werden wegen der Notwendig-_-keit, Gewicht zu sparen, im allgemeinen nicht mit Gegengewichten, sondern mit Federn ausgeglichen.Sliding windows for: vehicles, - - especially railroad cars because of the need to save weight, generally not with counterweights, but balanced with springs.
Allen bekanntgewordenen Federausgleichern haftet der Nachteil an, daß Federn mit wachsender Spannung eine steigende Kraft ergeben, während; die erforderliche Hebekraft gleichgehalten werden muß. Man schaltet deshalb eine veränderliche Übersetzung zwischen Feder und Fensterrahmen, etwa in Form von Kurvenscheiben oder Hebelübersetzungen, die einerseits die Bauart der Fensterheber kompliziert, andererseits das Gewichterhöht.All known spring balancers have the disadvantage, that springs give an increasing force with increasing tension, while; the required Lifting force must be kept the same. You therefore switch to a variable translation between spring and window frame, for example in the form of cams or lever ratios, which on the one hand complicates the design of the window regulators and on the other hand increases the weight.
Die Erfindung bezweckt, diesen Mangel zu vermeiden. Als Hebefeder wird eine Bandfeder a verwendet, die auf einer Unterlage b. mit. .den Schrauben c befestigt ist. In Abb. i befindet sich das Fenster im geschlossenen Zustand: --Die,Bandfeder ist dann spiralig aufgewickelt. Mit ihr ist aufgewickelt das Drahtseil d, das am freien Ende der Feder befestigt ist. Das Drahtseil d ist über die Rolle e zum Fenster f geführt.' Dieselbe Einrichtung befindet sich rechts und links am Fenster. Wird das Fenster durch den Handgriff g nach unten bewegt, so rollt die Feder a auf der Unterlage b, -durch den Zug des Drahtseiles d bewegt, ab, bis sie bti'm;geäffnet;°a@ Zustän@dnd@es-F!.ems@t@rs düse am A:bt@: _- dargestellte Stellung einnimmt. Dabei übt die Feder a auf das Drahtseil d immer annähernd die-- selbe Kraft aus, da der Hebelarm des Kraftangriffes an- der Feder lt praktisch dieselbe Größe behält. Das Gewicht des Fensters wird also in allen Stellungen ausgeglichen sein.The invention aims to avoid this deficiency. As a lifting spring a band spring a is used, which is on a base b. with. .the screws c is attached. In Fig. I the window is in the closed state: --The, ribbon spring is then wound up spirally. With it is coiled the wire rope d that is on free end of the spring is attached. The wire rope d is over the pulley e to the window f led. ' The same facility is on the right and left of the window. Will If the window is moved downwards by the handle g, the spring a rolls on the Pad b, - moved by the pull of the wire rope d, down until it bti'm; opened; ° a @ States @ dnd @ es-F! .Ems @ t @ rs nozzle on A: bt @: _- assumes the position shown. Included the spring a always exerts approximately the same force on the wire rope d as the The lever arm of the force applied to the spring is practically the same size. That The weight of the window will therefore be balanced in all positions.
Es ist natürlich auch möglich, die Feder wie in Abb. 3 anzuordnen oder so wie in Abb. q., wenn über dem Fenster genügend Platz ist. Dieser Ausgleich läßt sich auch zum Ausgleichen von anderen Teilen, wie Schiebetüren, Sonnenblenden oder auch Maschinenteilen, verwenden. Die Feder kann aus einem oder mehreren Blättern bestehen. Auch ist es möglich, durch Änderung des Befestigungspunktes der Rolle e statt der gleichbleibenden Zugkraft im .Drahtseil eine steigende. oder fallende zu erzielen.It is of course also possible to arrange the spring as shown in Fig. 3 or as in Fig. q., if there is enough space above the window. This compensation can also be used to compensate for other parts such as sliding doors, sun visors or machine parts. The spring can consist of one or more leaves exist. It is also possible to change the attachment point of the roller e instead of the constant tensile force in the wire rope, an increasing one. or falling to achieve.
