AI Technical Summary
Existing opening devices for sliding windows with pressure frames require complex handling involving two movements and are prone to unreliable coupling due to warping, leading to potential water ingress.
A rotary axis with an angled disc is integrated into the window frame, ensuring constant engagement with the pressure frame attachments, allowing the window to be opened or closed by turning a handle that pulls the window along a transfer bar, eliminating the need for separate hook coupling.
Simplifies the operation to a single movement, enhances reliability by preventing warping issues, and ensures secure closure to prevent water ingress.
Description
[0001] Opening device for sliding windows with pressure frame. - The object of the invention is an opening device for sliding windows with Printing frame and translation strip by means of a rotating axis arranged in the window jamb and operated by means of a handle.
[0002] In these known devices, to open or close the sliding window, the axis of rotation must first be moved horizontally and then it is coupled to the window frame by turning a hook, which is then brought into engagement with the frame.
[0003] The handling is made very easy by the execution of the two movements and, moreover, by the reliable engagement of the The coupling hooks in the window frame are not guaranteed by warping of the frame or the like. The novelty of the invention lies in the fact that it is firmly attached to the The axis of rotation is a disc arranged at an angle, which is constantly in engagement with projections of the pressure frame and rotates when the handle is turned. The axis pulls the window away from the water strip so that it can be pushed into the window shaft.
[0004] In the drawing, an embodiment of such a sliding window is shown in longitudinal section, specifically in Fig. i in the closure- and in Fig. 2 in an intermediate position.
[0005] The printing frame a, which is mounted in a known manner at the top of the stock b so as to be pivoted in and out, has on its underside the hook-shaped, downward-pointing fittings c, while a second, similarly designed, Upward-facing fitting d is arranged on the frame e of the sliding window f. The frame e also has a transfer strip e@. The Fitting c is designed as a guide for a disc h, which sits obliquely on the axis of the handle g and is used to move the pressure frame a. serves.
[0006] The operation and function of the sliding window is as follows: Fig. i shows the window closed. In this position, the Fittings d fit into the fittings c of the pressure frame a, through which the window f is tightly closed. The transfer strip ei lies in the closed position. The window on the water seal opens and holds it in the closed position, preventing water from entering. When the window is opened... f The handle g is rotated by i 80° and thereby the printing frame a is pivoted outwards by the inclined disc k (see Fig.: a). Through the With the interlocking fittings c, d, the window f is simultaneously pulled out of the window opening, so far that the window is after can be pushed downwards. When the latter is pulled upwards, fitting d engages with fitting c, and by turning the handle g the Window closed again.
[0007] The lifting device of the window is not shown and can be any type. It should also be mentioned that for frameless windows only the lower crossbar e is arranged.
Claims
[0008] PATENT CLAIM: Opening device for sliding windows with pressure frame and transfer strip by means of a device arranged in the window jamb and by means of a handleable rotating axis, characterized in that a disk (h) is fixedly arranged obliquely on the rotating axis, which with attachments (c) of the printing frame (a) is permanently engaged and when the handle (g) or the axis is turned, the window is separated from the water strip (k) pulls away so that it can be pushed into the window shaft.
