description

The invention relates to a stay for window sashes with a fixed window frame attached Holder and at least one pivotably arranged on the holder cooperating with the window sash to be held Holding arm, which holds the window sash in position for securing the window sash having.

In one known from DE-GM 75 24 43fi The retaining arm is firmly screwed to the fixed window frame and around a horizontal axis and to a certain extent also pivotable about a vertical axis. The locking device is now fixed arranged on the outer frame and is perceived as annoying here. Also one needs for each one to be secured Window a special lock. With the well-known locking device, the window sash can only be opened in be fixed in a fixed, non-variable angular position, the opening angle being relatively small.

so that e.g. when cleaning the windows the windows;: - outer surface due to the small opening angle is difficult to access.

The object of the present invention is to improve the locking device of the type mentioned at the outset in such a way that that it can be easily removed and reattached for any window, with

at the same time the opening angle of the secured window sash should be variable within wide limits.

To solve this problem, the invention provides that the holder as a U-shaped on the fixed window frame Slidable and removable clamp holder is formed that at the end of the support arm a second U-shaped clamp holder is provided for the releasable reception of the frame of the Window sash, the second clamp holder being articulated is articulated on the support arm and that both pivot axes of the support arm are parallel to the pivot axis of the Casement run.

By designing the holder as a U-shaped

This can be clamped at any point on the outer frame, and the second clamp holder at any point Place the frame of the window sash, so that with the same length of the Holding arm the opening angle of the window sash can be varied within wide limits. Simultaneously can easily be removed from the window and for another due to this training Windows can be re-used, which is particularly advantageous for window cleaning. Included handling is convenient and easy. No tools are required for handling.

In a further development of the invention, the bracket the two open sashes of a double window are hinged to the second bracket with a further holding arm be, at the free end of which a third clamp holder is provided for the second bracket, wherein then also the two pivot axes of the further holder run parallel to the pivot axis of the window sash. To clean a double window, the two open sashes are then secured in position and it both hands are free for cleaning. After cleaning, the wings are kept open safely, so that without Risk of slamming, the panes can dry off.

Even a sudden draft of air, for example when a door is opened, cannot slam the window sash cause.

To simplify the attachment and for space-saving storage, the pivotable articulations between the clerical holders and the Bracket arms can be simple plug-in connections so that the clamp holders are individually clamped to the frame and only then can the holding arms be attached. The plug connections are expedient for this purpose each formed by a bearing journal and an adapted bearing bore.

Particularly weight-saving and easy to handle, the holding arm can have a rod bent at both ends be, the two bends each give off a bearing pin.

To save a special securing of the plug connection, this is done by simply plugging it in from above, so that the plug connection is positively maintained by its own weight he follows.

To produce the clamp connection, the clamp holder can be one in one leg of the holder have guided clamping screw with a clamping plate which can be pressed against the frame.

For secure fixation, the clamp holder can be a clamping screw guided in one leg of the holder have with a clamping plate that can be pressed against the frame. Another embodiment that is can be adapted more quickly to different frame thicknesses, one can be guided in the leg of the bracket Guide pins have one arranged at the inner end of the guide pin against the frame pressable clamping plate. It can also be advantageous between the clamping plate and the leg of the clamp holder a compression spring guided through the guide pin can be provided, so that a force-fit fixation of the clamp holder takes place.

To protect the surface of the window frame the clamp holder is provided with an elastic layer on at least one but preferably on two legs that comes to rest on the frame. The layer can be made of rubber or a rubber substitute

education with only one holding room.

The same reference numerals are used for the corresponding parts for all exemplary embodiments. The window shown in FIGS. 1 and 2 has a fixed window frame 2 which is inserted in a wall 1 and to which a window sash 4 is articulated so as to be pivotable about a vertical pivot axis 3. A U-shaped clamp holder 5 is slipped over the lower leg of the window frame 2 and tensioned by a clamping screw 6. Finally, a second clerom holder 5 'is clamped from below on the frame 7 of the window sash 4, which is also fixed by a clamping screw 6 *, not shown in FIGS. Both clamp holders 5, 5 ¹ are provided with a horizontal rib 8, 8 ¹ , in each of which a bearing bore 9, 9 ¹ for bearing bolts 10, 10 * of a holding arm 11 are arranged. The length of the holding arm 11 can usually be somewhat shorter than the window sash width, so that, depending on the attachment of the clamp holders 5, 5 *, the window sash 4 can be fixed between only a small opening up to the maximum possible opening.

Due to the vertical arrangement of the bearing bores 9, 9 ¹ and bearing bolts 50, 10 ', the clamp holders 5, 5'
