GERMAN PATENT OFFICE

The invention relates to a device on windows with incorporated ventilation blades, in which the main sash is locked as soon as the ventilation sash is open. Devices that serve this purpose are already 'known. Here is the closure of the main wing with the closure of the ventilation wing combined, so both closures are activated by one actuating device put into effect. Such a device is very complicated and therefore sensitive against the effects of damage when opening and closing the respective wing type. For example In the event of slight inhibitions, the further movement required to open the ventilation sash can be carried out the closure member can be prevented so that the ventilation flap can no longer be opened. This occurs particularly with windows, the material of which is sensitive to atmospheric influences. The invention now deals with a simple device for preventing the opening of the main wing when opening the ventilation sash. According to the invention, a device is provided on the ventilation wing attached, which the locking rod (Basquille rod) of the main wing when open Ventilation wing directly through the ventilation wing or via a steering linkage in the closed position locked and only released again when the ventilation sash is closed. The actuation of the

Ventilation wing * is independent of the locking mechanism of the main wing. There is, however, a guarantee that the main wing will in any case uiiUt must be locked when the ventilation blade should be opened. A locking bolt for locking of the wing in the closed position only intervenes when the main wing is closed is completed.

In the drawing represents

Fig. 1 is a view of the upper part of a main wing frame with built-in ventilation wing and an exemplary embodiment of the invention Device represent;

Fig. 2 shows the cross section with unlocked locking rod and

3 shows the cross section with the locking rod secured.

On the main sash frame 1, the locking rod 2 is arranged, which serves as a cross bar 3 slides, which is articulated in a connection point 4 on the ventilation wing 5.

The Ouerriegel 3 is guided in .ein elongated hole 6 via a Führuiigsschraubc 7, which is in the main wing frame 1 is held.

The locking rod 2 has a recess S into which a projection 9 of the cross bar 3 slides and thus locks the locking rod 2 when the ventilation flap 5 opens.

In Fig. 1, a locking lever) o is shown, which is mounted on an I lallewinkel ι 1. Next is In Fig. 1, in a dash-dotted arrangement, the opening 2 of the ventilation wing 5 can be seen. Ever according to the roller arrangement of the ventilation sash on the main wing, the actuation of the open bolt 3 can also be done via a linkage arranged on the ventilation wing. In this case the designation means 5 a handlebar for actuating the Ouerriegel 3.

To better illustrate the invention Device is shown in Figs. 4, 5 and 6, the installation on a window, for example.

Fig. 4 shows a cross section through the window mil ventilation wing, with the actuating linkage for the closure is shown in full view with the ventilation wing open. There will also be a Operating handle 13 with a rod 14 for locking lever mechanism shown.

Fig. 5 shows the side view of the locking rod with the ventilation wing 5 and closed 6 shows the front view of the window with built-in ventilation wing 5.

The device shown in the drawing deals only with an exemplary embodiment of the locking device for securing the ventilation sash on the main sash of windows according to the invention. There are also other embodiments easily possible without deviating from the inventive concept.

Claims (3)

Patent claims: 1. Device for locking main sashes in windows with integrated ventilation sashes. l> ei those of the main sash of the window when the ventilation sash is opened locked and only when closing the ventilation wing the locking rod to operate the Closure on the main wing is released, characterized in that when opening and Closing the ventilation wing (5) directly or indirectly via a steering device Cross bolt (3) is actuated, which on the one hand is attached to the ventilation wing (5) and on the other hand on the profile (1) of the main wing and on the locking rod (2) through an elongated hole (6) so is performed that the cross bar (3) when opening the ventilation wing (5) the locking rod (2) locked on the main wing and only after closing the ventilation wing «(5) again releases. 2. Device according to claim 1, characterized in that that the locking rod (2) has a one-sided recess (8) into which a correspondingly shaped projection (9) on Cross bar (3) when opening the ventilation sash (5) engages and the locking rod (2) locked so that an actuation of the lock of the main wing is not possible. 3. Device according to claims 1 and 2, characterized in that go for the elongated hole (6) of the Ouerriegel (3) on the profile (1) of the main wing a Fübrungsscrew (7) is arranged, which at the same time as a stop for »the projection (9) of the Ouerrriegel (3) when opening the ventilation sash (5) is used.
