Abstract

The invention relates to a window handle with child-proof protection against unauthorised opening. To make opening difficult, for this purpose, a retaining lever (2) is mounted pivotably in the handle part (1). The retaining lever (2) is under the load of a compression spring (4). Its free end is supported on an intermediate rocker lever (5). One end of the latter carries a polygonal pin (7) arranged at right angles. The latter cooperates with a shaft (8) of a driving bolt, which shaft is mounted rotatably in the handle part (1) and has a cavity (9) designed according to the pin (7). A compression spring (10) keeps the lever (5) at a distance from the shaft (8). Only by overcoming this compression spring (10) and the compression spring (4) is it possible to make the coupling between the pin (7) and shaft (8), by exerting actuating forces exceeding the normal level and to operate the window fastening effectively. <IMAGE>

Description

Fenstergriff mit Sicherung gegen unbefugtes Öffnen Window handle with protection against unauthorized opening

eines Fensters Die Erfindung betrifft einen Fenstergriff gemäß Oberbegriff des Hauptanspruches. of a window The invention relates to a window handle according to the preamble of the main claim.

Es sind Fenster- und Türgriffe bekannt (DE-AS 1.047.059, 1.113.649 und 1.113.650) welche mit einer Kupplung oder einem Verriegelungsgriffstück ausgestattet sind, jedoch auch von Kindern leicht bedient werden können.There are window and door handles known (DE-AS 1.047.059, 1.113.649 and 1,113,650) which are equipped with a coupling or a locking handle but can also be easily operated by children.

Weiter wurden Türgriffe mit sogenannten Druckknopfsicherungen für Kraftfahrzeuge bekannt, die aber als Fenstergriffe keine Anwendungen finden können.Next were door handles with so-called push-button locks for Motor vehicles known, but can find no applications as window handles.

Aufgabe der Erfindung ist es, einen Fenstergriff mit Sicherung gegen das Öffnen von Fenstern durch Kinder zu schaffen.The object of the invention is to provide a window handle with protection against to allow children to open windows.

Gelöst ist diese Aufgabe gemäß der Erfindung dadurch, daß daß im Griffteil ein Sicherungshebel mittels eines Bolzens schwenkbar gelagert und von einer Druckfeder druckbeaufschlagt ist, und zwar unter Zwischenschaltung eines mittels eines Bolzens schwenkbeweglich gelagerten Hebels, an dessen einem Ende ein rechtwinklig angeordneter Zapfen liegt, der eine mehreckige Ausbildungsform aufweist und in eine im Griffteil drehbar gelagerte Welle, die eine gemäa dem Zapfen ausgebi!-dete Höhlung besitzt, einrastet, und daß eine Druckfeder den Hebel im Abstand zur Welle hält.This object is achieved according to the invention in that that in the handle part a safety lever pivoted by means of a bolt and supported by a compression spring is pressurized, with the interposition of a by means of a bolt pivotably mounted lever, at one end of which a right-angled Pin lies, which has a polygonal shape and in one in the handle part rotatably mounted shaft, which has a cavity designed according to the pin, engages, and that a compression spring holds the lever at a distance from the shaft.

Die Unteransprüche sind vorteilhafte Weiterbildungen des Fenstergriffes.The subclaims are advantageous developments of the window handle.

In der Zeichnung wird der Erfindungsgegenstand anhand eines Ausführungsbeispieles näher dargestellt.In the drawing, the subject matter of the invention is illustrated using an exemplary embodiment shown in more detail.

Im Griffteil 1 ist der Sicherungshebel 2 in einer Nut mittels des Bolzens 3 schwenkbar gelagert und wird von der Druckfeder 4 in Ruhelage gehalten. An dem oberen Ende des Sicherungshebels 2 liegt der Hebel 5 an, welcher mittels des Bolzens 6 schwenkbar gelagert ist und an seinem unteren Ende einen mehreckig ausgebildeten Zapfen 7 rechtwinklig angeordnet hat. Im waagrechten Innenraum des Griffteiles 1 ist die Welle 8 radial drehbar gelagert, welche in ihrer halben Länge zylindrisch und deren aus dem Griffteil 1 herausragendes Ende vierkantig ausgebildet ist. Das zylindrische Ende der Welle 8 weist in Axialrichtung eine mehreckig ausgebildete Höhlung 9 auf.In the handle part 1, the safety lever 2 is in a groove by means of the Bolt 3 pivotally mounted and is held by the compression spring 4 in the rest position. At the upper end of the safety lever 2, the lever 5 rests, which means of the bolt 6 is pivotably mounted and at its lower end a polygonal trained pin 7 has arranged at right angles. In the horizontal interior of the Handle part 1, the shaft 8 is mounted radially rotatably, which in its half length cylindrical and the end protruding from the handle part 1 is square is. The cylindrical end of the shaft 8 has a polygonal shape in the axial direction Cavity 9.

Eine weitere Druckfeder 10 dient zum Abstandhalten des Hebelendes des Hebels 5 von dem Wellenende mit der Höhlung 9 der Welle 8. Die beiden Druckfedern 4 und 10 müssen so stark sein, daß nur durch die Kraft einer erwachsenen Person der Sicherungshebel 2 eingedrückt werden kann.Another compression spring 10 is used to keep the end of the lever spaced of the lever 5 from the shaft end with the cavity 9 of the shaft 8. The two compression springs 4 and 10 must be so strong that only by the strength of an adult person the safety lever 2 can be pressed in.

Bei Eindrücken des Sicherungshebels 2 und Überwindung der Federkraft der Druckfeder 4 und 10 wird der Hebel 5 mit seinem Zapfen 7 gegen die Welle 8 gedrückt und der Zapfen 7 greift in die Höhlung 9 der Welle 8 ein. Erst hierdurch kann der Fenstergriff radial verschwenkt und das Fenster geöffnet werden. Derselbe Vorgang im entgegengesetzten Sinn dient zum Schließen eines Fensters.When the safety lever 2 is pressed in and the spring force is overcome the compression spring 4 and 10, the lever 5 is pressed with its pin 7 against the shaft 8 and the pin 7 engages in the cavity 9 of shaft 8. Only then the window handle can be swiveled radially and the window opened. Same Operation in the opposite sense is used to close a window.

Der wesentliche Vorteil des erfindungsgemäßen Fenstergriffes liegt darin, daß nur eine erwachsene Person, jedoch aber kein Kind das Fenster öffnen kann, weil es nicht die erforderliche Kraft in den Händen besitzt.The main advantage of the window handle according to the invention lies in the fact that only an adult, but not a child, opens the window because it does not have the required strength in the hands.
