timiitrieb, especially for tilt and turn windows

The innovation concerns a window drive, particularly for tilt and turn windows. Mechanical window drives for tilt and turn windows are already known, with which the tilt and turn sash can be brought into the desired operating positions, for example via a gear mechanism. It is also known from window manufacturers to use positively controlled opening scissors via electric motors. There is also a desire to move normal windows, particularly tilt and turn windows, using an electric drive. In addition to the greater ease of use, the advantage is that all the windows in a building can be operated simultaneously if required via a control system, for example they can be closed from a control center if there is a sudden onset of wind or rain. In addition, individual control via a switch should also be possible.

The problem with normal windows is that the lock and the drive for the opening scissors are located on the sash. For this reason, it is difficult to operate them with an electric motor. Such a design was previously not considered possible.

The aim of the innovation is to provide an electric drive for normal windows, especially tilt and turn windows. This task is solved with the arrangement according to claim 1. Advantageous developments can be found in the other claims. It is irrelevant how the electric drive is implemented.

In a particularly advantageous design, an additional safety device is provided for the rotation position. This prevents the sash from being accidentally rotated when the rod is in the ready-to-rotate position. The safety device is particularly advantageously operated with a lock and locking cylinder.

For particularly large wings, where two scissors are arranged

both sets of rods are forced together via the rods.

For the rotational separation, it is advantageous if the power supply for the electric drive is switched off when the sash is opened. The switch can be provided in conjunction with the fuse, or a separate switching contact can be provided which comes into operation when the sash is rotated.

The electric drive is advantageously controlled via limit switches, whereby several limit switches can be provided, for example a limit switch for the closing position, a limit switch for the ready-to-turn position and a limit switch for the tilt position. Of course, intermediate positions are also possible in the tilt position.

It is particularly advantageous if the cable is fed through the hinge-side tilting bearing. There is only a slight relative movement between the sash and the frame, and the cable is therefore protected.

The tilting joint on the opening side is designed in such a way that it disengages in the turning | position so that the sash can then be easily opened. I

the tilt position is drawn.

The window sash is designated with (1) and the frame with (2). A rod (3) is arranged all the way around the window sash (1). This rod (3) is provided with locking pins (9) and with drive elements (not shown in detail) for the opening scissors (4,5) in the upper horizontal area. The locking pins (9) work together with locking plates (10) on the frame. The hinge-side tilt bearing of the fitting is designated with (20), the opening-side tilt joint with (15).

In the example, an electric drive (6) is drawn in the lower horizontal area. The electric drive can be of any design, for example a gear motor. The electric drive (6) is connected to the rod (3) via a connecting element (18). It is also possible to arrange the electric drive (6) on the frame, with the connecting element then engaging in the rod (3) of the sash via the rebate.

Limit switches are also arranged at the output of the gear motor, which automatically switch off the drive when the rod has reached the desired end position, for example the tilt position or the closing position.

prevents the sash from being accidentally opened when the rod is in the hinged position. This makes it possible to use the new window drive even when the operating sequence is on the rod: closed position - turning position - tilting position. In the example shown, the safety device (7) is provided as a lock with a cylinder. It is advantageous if the safety device (7) is simultaneously connected to a handle (19) for turning the sash.

The cable (11) for the electric drive (6) can advantageously be fed via the hinge-side tilting bearing (8). Only slight relative movements then occur, so that the cable is protected.

A switch (12) for the electric drive can be located on the frame or next to the window. However, it is also possible to attach the switch (12) directly to the electric drive (6).

Individual control switches such as rain detectors, temperature monitors, wind monitors or the like can also be connected. Then an automatic control of all windows in a building is possible with the

In this way, individual control switches can be superior.

The opening-side scissors (5) are connected to the rod (3)
via a drive element (14). A coupling ensures that the connection cannot be released, particularly in the tilted position, but only in the ready-to-rotate position.

At the lower opening-side corner, the ^tilt joint (15) is provided, consisting of a bearing part (Ib) on the rod (5) and
a counterpart (17) on the frame. Both parts engage with each other in the tilting position, while they can be detached from each other in the ready-to-turn position.
