Device for moving resettable frames, in particular window frames

Description

[0001] Device for moving resettable frames, in particular window frames. The invention relates to a device for Moving resettable frames, especially window frames. To clean the outer surface of such a window, it was previously possible It is necessary to detach the fittings located on the lower edges of the window frame from the frame itself, so that the window frame can be moved to It could be opened from the inside. However, this is very cumbersome and unwieldy, and such a window can easily break if handled carelessly.

[0002] To avoid these disadvantages and to make cleaning the window easier, it is proposed according to the invention to The resettable window frame can be detached on one long side from its pivoting elements anchored to the frame and on the to make the other longitudinal side pivotable around additional vertical axes provided on the pivoting elements. This makes it possible to the window frame, once it is set back, to pivot these vertical axes into the interior of the room, so that one can also see the The outer surface of the window can be easily cleaned.

[0003] In the practical embodiment of such a device, a bearing bushing is pivotably mounted at the end of the upper extension lever. attached, which is movable on an axis on the window frame. Similarly, a pivotable bearing bushing is attached to the lower support arm for Another axis is arranged. Of course, a single common axis could also be provided instead of the two axes. On the other The long side of the window frame is the awning arm with a spring-loaded mechanism. It is equipped with a guide bolt that can be pulled back when necessary, thereby releasing the window frame from the pivoting elements on that side.

[0004] For heavy window frames, a compression spring is attached to the extension arm to counteract the weight. For this purpose, A guide pin is steered on the ejector lever, around which the spring, covered by a tube and supported against a console, rotates. is arranged. Of course, such a spring, serving to balance weight and close, could also be used in other fittings. can be used.

[0005] The drawing shows an embodiment of a device according to the invention, namely Fig. i shows the front view of a Frame with the fitting, Fig. 2 'the side view of a recessed frame and Fig. 3 the compensating and closing spring in side view.

[0006] On the inside of the frame i, a rod 2 with the operating handle 3 is arranged in a known manner, wherein the rod 2 via an adjusting rod 4 acts on the upper release lever 5. This release lever 5 is connected to a shaft 6, at the other end of which the The extension arm 7 is arranged so that when the device is actuated, both the extension arm 7 and the extension lever 5 are pivoted.

[0007] According to the invention, a bolt 8 is rotatably connected to a bearing bushing 9 at the end of the extension lever 5. This bearing bushing 9 is slidable on a pin io, which is fastened to the frame 14 by means of two bearing blocks ii and 12 and the tab 13. At the lower end In the usual manner, a support arm 15 is located on the frame 14, which is attached to the frame i by means of the tab 16. This support arm The support arm 15 is doubly guided by means of two pins 17 and 18 in guide slots i9 and 20. This support arm 15 also receives a bearing bushing 21, which is... The bolt 22 is rotatable. This bearing bushing also engages a mandrel 23, the axis of which coincides with that of the mandrel 10.

[0008] The extension arm 7 on the other side of the frame is provided with a guide pin 24, which is under the pressure of a spring 25 and in a longitudinal slot of the tab 26, which is screwed onto the frame, engages. When the frame is tilted in the usual way, it shifts On one side the guide pin 24 is in the slot of the tab 26, while on the other side the bushing 9 is displaced on the mandrel 10 With a further rotation of the handle 3, the frame is lifted in the usual manner and guided through the slotted guides i9 and 20. reset, as indicated in Fig. 2. If the outer surface of the frame is to be cleaned, the handle end 27 can be used to... Pull back guide pin 24 to release the frame from the fitting at this point. The frame can then be moved around. Swivel the mandrels 10 and 23 to easily clean the outer surface.

[0009] To compensate for the weight of heavy frames during resetting, a lever arm 7 can be attached to the extension arm as shown in Figs. i and 3. A guide pin 29 is steered in a manner that carries a collar 30 against which a spring 31 is supported. The other end of this spring rests against a console 32, so that this compression spring can bear part of the frame's weight. The spring can be protected by a protective tube. 33 be surrounded. By adjusting the collar 30 on the thread located on the bolt 29, the spring force can be adjusted depending on the weight of the Frame adjustments will be made.
