AI Technical Summary
Existing adjusting devices for sliding windows require special tools for transverse displacement across the weather bar, which can be cumbersome and inefficient.
A resiliently arranged lever mechanism that bends transversely to the window's movement, allowing the window to translate via the weather strip without additional tools, using a gear and leaf spring or conical pin to facilitate automatic raising and lowering.
Enables automatic and efficient translation of sliding windows without the need for additional tools, reducing friction and ensuring smooth operation.
Description
[0001] Adjustment device for sliding windows. The invention relates to an adjustment device for sliding windows, in particular those for carriages, in in which a lever acting on the window is used to raise and lower it, and the window is automatically moved over the weather bar. is caused.
[0002] The invention differs from known devices for the same purpose in such a way that all The need for special aids to generate the lateral displacement of the window across the weather bar may be eliminated.
[0003] The invention consists in particular in that the end of the actuating lever that engages the window is arranged transversely to the The main direction of movement of the window is arranged in a spring-like manner, so that it gives way when the window hits the upper end of its guide and This is achieved by translating the window via the weather bar.
[0004] The drawing illustrates the invention in two embodiments. In Fig. i, one view is shown, and in Figs. 2 and 3... In the two longitudinal sections shown with the window in different positions, a gear b acts on the window a. fixed actuating lever c, which carries a pin d that engages in a slot e of a rail f attached to the underside of the window.
[0005] The actuating lever c is formed by a leaf spring, so that it can bend to a certain degree.
[0006] When the gear b is rotated by means of a transmission of any type, the window a is raised or lowered in a known manner.
[0007] When the window hits the upper end of its guide during lifting, the actuating lever c is located in the position shown in Fig. i. Position. The hook-shaped part g attached to the window then assumes the position shown in Fig. 2 with respect to the weather bar h. Further The actuating lever c is rotated by the pressure which arises between it and the window a as a result of the pane being pushed against its upper end. The guide is bent, so that it takes on the shape shown in Fig. 3 and thereby shifts the part g over the weather bar k, whereupon, with further rotation of the adjusting lever, the window is lowered slightly again, so that it comes into the position shown in Fig. 3.
[0008] Figs. a and 5 show an embodiment in which, in order to protect the window pane, the actuating lever c is not directly by a The disc is not bent by the pressure exerted on it, but a special device serves this purpose.
[0009] The actuating lever c carries a conical pin i which, when the window has reached its highest position, engages with a lug k on the The underside of the weather bar abuts. The conical shape of the pin i ensures that the deflection of the adjusting lever occurs without clamping.
[0010] To reduce friction, the pin i can be designed as a roller which is mounted on a fixed pin of the actuating lever c.
[0011] Instead of the actuating lever c formed by a leaf spring, a lever consisting of two rigid, resiliently connected parts can also be used. consists of connected parts which touch in a surface inclined to the plane of rotation of the actuating lever.
Claims
[0012] Pt'TfNT claims. i. Adjustment device for sliding windows, in particular carriage windows, with a lifting and lowering mechanism for the window. effecting lever and automatic translation of the window via the weather bar, characterized in that the end acting on the window the actuating lever (c) is arranged in such a way transversely to the main direction of movement of the window (a) that it is resiliently arranged when the window is bumped (a) yields to the upper end of its guide, thereby effecting the translation of the window (a) via the weather bar (lt).
2. Device according to Claim i, characterized in that the actuating lever (c) engaging the window (a) is formed by a leaf spring which, when the The window (a) is bent to the upper end of its guide in such a way that the window (a) is thereby translated over the weather bar (lt).
3. Device according to claim 1 and 2, characterized in that the actuating lever (c) engaging the window (a) has a conical pin (i) carries.
