The solution to this problem is after the push rod S _1, which in turn deflects 6 a drive rod 7 by means of a corner finding in a surprisingly simple manner. Achieved by the fact that the raising arm in or near the 45 this drive rod 7 is a raising device 8 sash pivot axis is hinged to the fixed frame exclusively for the purpose of tilting the sash 2 up and down. operated by a link arm moving an extension arm

The one in or near the wing pivot axis on the moves and with a coupling part 9 on the fixed-fixed frame only swiveling articulated frame i coupled.

The extension arm not only has the foreseeable effect, 5 ° Another extension device with an extension a falling down of the pivot opening actuating arm 10 is in or near the vertical pivot position incorrectly operated wing is reduced. Over-axis of the wing 2 via a bearing 11 exclusively surprisingly, it is rather articulated by the pivotable pivotable. With wings 2 small width bare articulation of the extension arm in or near the it is possible, only the last treated opening sash pivot axis to be provided on the fixed frame in the active device.

connection with the via its curve guide on the expediently concealed between the Attacking the wings and arranged from the upper hill and frame wood located on the hill borrowed tilting operating linkage from controlled raising device has except their raising arm Link arm also achieved the essential advantage that 10 still has a link arm 23, which is involved in the driving the 60 rod 7, which is incorrectly operated in the pivoted open position, is articulated at one end and On the other hand, the wing from the locking mechanism exerts an actuating force via the pin 24 on the extension arm 10 can be exercised, which attacks the wing in parallel.

aligns with the extension arm. In this alignment position While one of them, for example, can be used with a even a heavy hill can be easily turned into an angled end of the extension arm 10 Be brought to a position in which the pivot 65 is held in the bearing 11 such that it can pivot about the axis 20 joints are aligned again and also through loading, the other end hinged on hill 2 slides actuation of the locking mechanism re-engaged with a pin 26 in a longitudinal slot 27 of the will run.

The handlebar 23 is on the wing side over the pin 30 is connected to the drive rod 7, which extends through the guide slot 31 of the cover rail 21. It also has a curved guide in the form of a slot 28 into which a on the cover rail 21 stationarily attached roller pin 29 engages. If the drive rod 7 is from the locking mechanism 4 shifted, dar.n the link arm 23 is taken along accordingly and over the curve guide 28,29 compulsorily from the position according to FIG. 4 in d: position according to FIG. 2 or vice versa emotional. So he sp.-izt opposite the extension arm 10, so that it is pushed away from the wing 2 and the wing is thereby turned off from the fixed frame 1 will.

The connection between the link arm 23 and the extension arm 10 is shown in FIGS. 2 and 3 from the pin 24 on the link arm 23, the between the U-shaped bent cheeks 22 of the extension arm 10 slides However, it is particularly advantageous to use the ao Link arm 23, as shown in FIGS. 5 and 6 shown with its pin 24 in a longitudinal slot 33 of the extension arm 10 to allow slidable engagement. To stabilize the weakened by the longitudinal slot 33 Extension arm 10 is provided in this case a cover sheet 35, whose bent in a U-shape Legs 38 engage in notches 39 of the extension arm 10. By rivets or the like Penetrate holes 34 and 37 in the extension arm 10 or in the cover plate 35, the latter is fixed to the Extension arm 10 connected. The cover plate 35 increases. or not just the stability of the extension arm 10. Rather, it also covers the longitudinal slot 33 reliably against the ingress of dirt and Color and allows an unimpeded sliding movement of the pin 24 through its bulge 36.

If the hill 2, after it has previously been around the fish tape pairs 14, 15 and the corner bearing 17 with Corner tape 16 has been pivoted into the open position, misused by the fish tape pairs 14,15 are accidentally or deliberately uncoupled, then the wing 2 is still hanging on the opening device at the top 10. Since both the extension arm 10 and the control arm 23 on the flights! attack, it is possible by moving the operating lever 3 accordingly, via the locking mechanism 4 to always press the sash 2 in a parallel position to the extension arm 10. In this parallel position a heavy wing 2 can easily be brought into a position in which the fish tape pairs align again, so that the via a corner drive 12 and a drive rod 13 with the Driving rod 7 coupled Fitschenschieber, also by actuating the locking mechanism 4, the Restore the articulation between the pairs of fish straps 14 and 15.

The return of the wing 2 from a misused Position in a parallel position aligned with the pivot axis to the extension arm 10 is through the power transmission on the link arm even with large and therefore heavy sashes 2 without exertion possible, so that any other safeguard against incorrect operation of the turn-tilt sash can be avoided can.

Claims (3)

Claim "· 1. Opening device for windows and doors or the like with turn-tilt sash, in which an opening arm connects the sash to the fixed frame to limit the tilting opening movement and for the forced opening and closing of the wing over someone attacking it Link arm, which is supported by a curved guide on the wing, with a movable from the wing locking mechanism and on the sash is connected to the tilt actuation linkage, characterized in that, that the extension arm (10) in or near the wing pivot axis (14,15,16,17) on Fixed frame (1) is hinged exclusively to pivot (11, 20). 2. Display device according to Arsprurh 1, thereby characterized in that the extension arm (10) has a longitudinal guide (22 or 33) with which the link arm (23) is in drive engagement via a pin (24). 3. Display device according to claim 2, characterized in that the longitudinal guide of the Ausstellarmes (10) is formed by a longitudinal slot (33), this longitudinal slot of a cross-sectionally U-shaped cover plate (35, 38) is overlapped, which has a bulge (36) for receiving the pin (24) and as a stiffening means fixed to the extension arm (10) is connected.
