According to an advantageous embodiment of the invention the rollers, by which the movable frame is held on the roller rail, can be in the closed position are on inclined surfaces that limit the notches of the rail, so that the dead weight of the frame holds this against the frame.

The fitting according to the invention is simple and stable and has the advantage of great puncture security, especially with regard to the seal, the simplicity of operation, the effectiveness of the locking and the very limited number of individual parts of the 3 fitting.

In the drawing, an embodiment of the invention is shown as an example. Show it:

The rail 3 contains two runways 3a and 3o, which run parallel to one another and are separated from one another by a central groove 3c. The runways

3a and 3b each have notches 11 'and 12 at suitable points, which are used to accommodate the rollers 6 and 7 at the \ -) end of the closing movement of the movable frame 1

In addition, the roller 6 has a large annular groove

From Figures 4 and 5 it can be seen that the rollers 6 and 7 are identical, but they are one Longitudinal plane symmetrical to each other.

The frame is in the closed position (Fig. 3, 4 and 5) 1 lowered so far that its lower edge la touches the roller rail 3. However, if the moving frame is in a partially open position (Fig. 6 and 7), the rollers 6 and 7 are no longer in the notches 11 and 12 and it follows that the frame 1 in relation to the frame 5 is raised.

The actuation and locking mechanism works like this:

Frame 2 is in the closed position (Pig. 9) never lowered onto the roller rail 4, as described above would. The frame is then opposite the mechanism 9 in such a way that the pawl 28 can pass through the opening 35 and secure the locking of the frame 2. Furthermore, the bolt is 27 withdrawn under the action of the tension spring 26 as far as the rear wall of the housing 22. The handle 21 is located in a vertical position.

To open the handle 21 is shown in the direction of the arrow Pigel, turned. This causes the pivot 25 to call a Rotation of the control disk 24 in the same direction that lifts the pawl 26 during the entire rotation before the bolt 27 touches the part 34, which happens through the projection 28a of the pawl 28. The control disk 24- and the pawl 26 are designed so that the latter remains in its raised position as long as the control disk 24 is not substantially in its rest position has taken again. As a result, the shock exerted by the bolt 27 can be freely applied to the part impact. It is clear that the lever 21 is so long that the force exerted is as small as possible, the rotary

The path of the push pin 27 is so great that the Rollers 6 and 7 can emerge from their notches 11 and 12 and return to the runways.

Under the effect of the impact, the frame moves away 2 of the frame 5 and can still be operated with the help of a cup-shaped handle that is in the pillar of the frame is embedded. When the frame is in the roll; -. Division, it is sufficient to let go of the lever 21, since this then returns to its vertical starting position, and the parts of the housing 22 turn back to its rest position shown in Pig.9.

As is readily apparent, the lock is of the frame 2 very securely, i.e. the pawl 28 cannot be made to snap out even then v / ground when attempting to raise frame 2 by any means.

According to another. Embodiment of the invention the runway can be provided on the upper part of the window. Likewise, it can also be used in the case of a single wing Window, the actuator housing 22 on the relative Frame be attached without these embodiments deviating from the inventive concept.

When frame 2 is to be opened, i.e. that if it is shifted to the left in Fig. 12, the rollers 6, 37 and 47 roll onto the upper edge of the rail 3, and the frame is raised. It's from Pig. 14 it can be seen that the end of the opening path, the pair of rollers 37.47 reaches the second notch 11. Assuming that the distance d is greater than the length a of this notch, is one of the rollers 37,47 always in contact with the upper edge of the rail 3, while the other can float over the notch 11. In this way, the frame 2 can be moved into this zone of the rail 3 without the danger of it sinking.

Of course, the rollers 37 and 47 can be spaced apart by a distance d in one and the same housing be coupled, which enforces this distance d and thus avoids any positional error.
