It is known, as an opening and closing device for tiltable about a horizontal axis of windows windows on the inside of the wing with a cross bar od. Like. Attempting to use Ausstellarme, which are arranged laterally of the wing. The extension arms are hinged to the stationary frame, each with a bearing pin on the opposite end of the cross bar, wherein the bearing pin is slidable in a vertical longitudinal slot. A mounted approximately in the middle of each stay arm horizontal guide pin cooperates in the closed position with a guide arranged on the fixed frame, which is inclined to the vertical stop plane of the wing. The extension arms slide downwards by their own weight and press the wing against the fixed frame and serve as opening arms in this position.

It is the object of a Ausstell- and closure device, which is particularly suitable for concrete windows to create, which is as simple as possible.

This object is in a display and closure device for tiltable about a horizontal axis wings of windows, especially concrete windows, consisting of od on the wing inside with a cross bar. Like. attacking Ausstellarmen, which are arranged on the side of the wing, horizontal pins and longitudinal slots are hinged, and a guide which is inclined to the vertical stop plane of the wing and in which the two Ausstellarme slide by its own weight in the closed position for pressing the wing down, thereby solved that the guide is formed by a wall of an obliquely arranged in the opening and closing arm longitudinal slot, which cooperates with a pin fixed to the fixed frame and the fold of the fixed frame as a stop, so that the extension arm from an almost horizontal open position by about 90 ° in a vertical, parallel to the fixed frame closed position is tilted.

In the device according to the invention, a pin and almost all the fitting is saved on the fixed frame. In addition, in this closing and Ausstellvorrichtung in the closed position no beyond the fixed frame protruding parts more available.

A further embodiment of the device according to the invention is that the longitudinal slot forms with its lower end a bearing recess for pivoting the extension arm. In a preferred embodiment of the invention, latching points are arranged on the outwardly lying side of the longitudinal slot for engagement with the pin, wherein the planar raising and closing device

Louis Schierholz, Bremen-Kattenturm, is named as an inventor

Surface at the articulation end of the extension arm is supported on the fold of the fixed frame, so that the wing is set in partial open positions. In addition, the crossbar may be performed in a conventional manner on the wing by means of a bracket, which has in a known manner latching points for securing the wing.

The drawing illustrates an embodiment of the invention. It shows

1 is a concrete window in vertical section with fully and half-opened wing,

2 is a vertical section with closed wing,

Fig. 3 is a partial view of the section along the line III-III in Fig. 1 at half-opened wing.

The figures illustrate the application of the invention to a concrete window. The wing consists of a glass pane 1 and U-shaped side frames 2 with rubber lining and is tiltable about its in a storage groove 3 of the fixed frame 4 loosely resting lower edge. The wing is held by a crossbar 5 which is fixedly connected to Ausstellarmen 6. The extension arms are rotatable about fixed in the side parts of the fixed frame 4 pin 7.

The crossbar 5 is guided between brackets 9 and the side frames 2 on the wing 1, 2. In order to avoid that by wind or draft of the wing 1, 2 strikes, the bracket 9 are provided with a catch 10 for engagement and retention of the crossbar 5 in the open position. A corresponding rest can also

for the dashed lines in Fig. 1, half open position in the upper part of the bracket 9 may be provided.

The crossbar 5 engages only in the area of ​​the side sockets 2 on the wing, while it is bent away in its lying in front of the disc 1 middle part of the wing. In this way the handling is facilitated.

In the extension arm 6, an oblique guide slot 11 is arranged for receiving the pin 7. The extension arm 6 has at the articulation end support surfaces 12, 13, 14, which bear against the fold 15 of the fixed frame 4 in the associated position.

From the fully open position of the wing reaches the half-open position by simply swinging the Ausstellarme 6 using the crossbar 5, with the crossbar 5 in the slot 8 pushes upwards. The catch 16 comes over the pin 7 and coincides with simultaneous stop of the support surface 13 at the fold 15 a. From this position can be brought by simply further pivoting the wings in the closed position (Fig. 2). Subsequent to the pivoting stroke, the crossbar 5 is pushed with the Ausstellarmen 6 down, so that the upper end of the slot 11 comes close to the pin 7. The support surface 14 comes with the frame surface 15 to stop. The wing is pressed by the rod 5 firmly against its stop. In this case, the deflection end 17 of the guide slot 11, which cooperates with the pin 7, serves as the bearing of the extension arm 6 which cooperates with the pin 7. In the open position of the wing 1, 2, the flat surface 12 abuts against the fold 15 of the fixed frame 4. In partially open position of the wing of the pin 7 engages in the latching point 16 of the guide slot 11, while the surface 13 of the stay 6 serves as a stop on the fold 15 of the fixed frame 4. The part of the guide slot 11 which faces towards the crossbar 5 acts as a closure device in that the oblique part 18 of the guide slot 11 slides along the pin 7 until the surface 14 abuts against the fold 15 of the stationary frame.

By inclined to the longitudinal direction of the extension arm 6 guide slot 11 a wedge-like closure is achieved with Andrückwirkung.
