In the figures, 20 denotes the stationary frame and 21 denotes the wing, which is designed on the one hand as a sliding wing and on the other hand is pivotable about a vertical axis AA. To guide the wing 21 as a sliding wing, two pairs of S-shaped or angular sliding guides 22, 23, 24, 25, designed as slots or grooves, are used, in which the wing 21 is guided in points B and C, D and E adjacent to its four corners is, the weight of the wing 21 being borne by the fixed frame 20 at the same time in points B and C. The points B and D lie in the pivot axis AA of the wing 21.

χ 5 The operating linkage for the wing 21 consists mainly of an actuating linkage 26, a Lock linkage 27 and a further coupling rod 28. The lock linkage 27 in turn has two individual ones Lock rods 29 and 30, which by an operating member 31 by means of a gear 32 or other suitable gear means can be moved in opposite directions. The upper end of the locking bar 29 engages in the locking position of the wing 21 in a bore 33 or acts with another counter-locking member in or on the upper cross member of the fixed frame 20 together, while the lower End of the lower locking rod 30 engages in a bore 34 or in a corresponding manner with a Counter-locking member cooperates in or on the lower cross member of the fixed frame. For locking of the wing 21 on the side edge of the same serve locking plates 35, which in the usual way with vertical slots closed at the front by walls 36 are provided in which locking pins 37 can enter the locking bars 29 and 30 from below or from above.

On the locking bars 29 and 30 stops 38 and 39 are arranged, which cooperate in pairs with counterstops 40, 41, or 42, 43 with an idle stroke 44 and 45, when the locking bars 29 and 30 in the direction of arrow X ₁ or x ₂ or be moved vertically in the opposite direction.

The counterstops 42 and 43 are arranged on the lower coupling rod 28, which at its lower end carries a guide member 46, for example in the form of a roller, for the lateral support of the wing and in which in FIG. 1 position of the rod engages in the angled end 25 α of the sliding guide 25 at right angles to the plane of the wing.

The counterstops 40 and 41 are located on an actuating rod 47 which, together with a further horizontal actuating rod 48 and a vertical actuating rod 49, forms the actuating rod 26, the individual actuating rods being driven by deflection gears, e.g. B. in the form of guide chains 50 and 51 are connected to each other in such a way that the actuating linkage 26 can be moved as a whole in the direction of the arrow ^ ₁ or in the opposite direction.

A coupling or locking member 53 is arranged on the upper control rod 48 by means of an arm 52, which with the guide member 54 at point C in the manner to be described later for coupling of the wing cooperates with the guide member or for decoupling the wing from this. With the control rod 49 is also connected to a locking rod 55, the upper end of which is a locking pin 56 is formed, which has a sleeve 57 fixedly connected to the wing 21 and a sleeve attached to this sleeve

of the wing, while the locking slot 65 separated from it by a wall 36 is a Position 37 ″ of the locking pin 37 is determined when the wing is slightly open and thus in the ventilation position is set. If space permits, bolt slots can be used instead of two 64 and 65, a plurality of which may also be provided or the same have a greater distance from one another.

In the embodiment according to FIG. 4, the arm 52 for the locking member 53 also forms one piece with the adjusting rod 48, while the deflection chain 50 is connected to a special rod 48 α and this is connected to the adjusting rod 48 by claws 66 or the like.

The F i g. 5 to 7 show the actuation of the coupling rod 28 by the locking rod 30 by means of the stop 39, which is welded to the locking rod 30 as an angle plate and engages in a flattened area 67 attached to the coupling rod 28, which is provided at its ends by the counter-stops 42 and 43 serving wall parts is limited. A roller is used as the lower guide member 46, which is placed on a pin 28 a of the coupling rod 28 and engages in the sliding guide 25 on the fixed frame 20 in the locking or sliding position of the wing, but during the stroke a ₂ to achieve the pivoting position of the wing is excavated from this sliding guide.

In a similar way, the adjusting rod 49, which is also multi-part and adjustable in length, actuates the Guide member 61 (Fig. 12) by means of the rod 60, which od to the actuating rod 49 by means of claws 68, pins. Like. Is connected to take along in the vertical direction. The role serving as a guide member 61 is open a pin 69 is placed on the rod 60 and is in the locking or sliding position of the wing at the height of the sliding guide 24, the width of which corresponds approximately to the diameter of the roller. The cone

69 is connected to rod 60 by a tapered neck

70 connected, the diameter d of which is equal to or smaller than the width of a slot opening 71 through which a bore 62 in a bolt attached to the fixed frame 20 part 72 is opened against the sliding guide 24 in the direction Z ₂ . In transom or sliding position of the casement or of the guide member 61 corresponding to FIG. 12, the neck 70 is in the amount of the latch member 72 so as to protrude through the slit opening 71 upon movement of the blade and thus of the guide member 61 in the direction of arrow Z _2, the neck 70 can. However, if the role serving as a guide member 61 is raised by the stroke α, into the position 61 'and thus inserted into the bore 62, it can _{not leave the bore 62 in the direction of arrow Z 2} and thus locks the wing against moving in the direction of arrow ζ or . Z ₂ . To facilitate the insertion of the roller into the bore 62, it is expediently conical at its upper end.

The F i g. 4,9 and 10 show one preferably Embodiment .; the guidance of the wing in the suspension point C.

The wing 21 has a projection 73 which can also be formed by a fitting and has a V-shaped recess 74. A hook-shaped coupling member 76 of the guide member 54 engages from above in the space 75 between this projection 73 and the locking member 53, which is preferably again formed by a roller and is rotatably mounted on a pin 53 b of the arm 52 with a vertical axis of rotation a. The hook-shaped coupling element 76 here engages around the projection 73 from above and below and is inserted into the V-shaped recess 74 of the projection 73. Against stepping out of the V-shaped recess 74, the hook-shaped coupling member 76 is secured by the locking member

53 prevented. The guide member 54 is in its upper part in a known manner as a pin

54 a and carries two guide rollers 77 and 78, preferably in the form of roller bearings. The guide rollers 77 and 78 roll on a profile guide rail 79 in such a way that the roller 77 is supported from above on an inclined surface 80 and the roller 78 on the opposite side against a vertical wall 81. In Fig. 9 shows the rail 79 rotated by 90 ° for the sake of clarity, since its arrangement per se corresponds to the end 25 α of the sliding guide 25 or the corresponding sliding guide 23.

A magnet 82 arranged on the stationary frame 20 serves to hold the guide member 54 on the stationary To secure frame 20 against shifting when it is uncoupled from the casement.

If the wing is set to the pivoting position, ie the locking member 53 is moved in the direction of arrow ^ _{1 of} the linkage so that it disengages from the hook-shaped coupling member 76 of the guide member 54, the wing 21 can be pivoted in the direction of arrow w together with the locking member 53 without to be prevented from this by the guide member 54 or its hook-shaped coupling member 76. The magnet 82 ensures that the guide member 54 remains in its position so that when the sash is pivoted back again, the V-shaped recess 74 on the extension 73 of the sash comes into engagement again with the hook-shaped coupling member 76 on the guide member.

Finally, FIG. 11 shows an exemplary embodiment for the suspension point B in the pivot axis AA. The locking bar 55 is connected to the adjusting bar 49 by means of entrainment elements such as claws 83, pins or the like and is guided on the casement within the sleeve 57. As in point C , the guide member 58 again consists of two suspension rollers 84 and 85, which are mounted on the upper end of the sleeve 57 and in the same way as the rollers 77 and 78 in the upper one (rotated 90 ° by dash-dotted lines in FIG. 11) Profile guide rail 86 are performed.

In the locking and sliding position of the sash, the upper end of the locking rod 55, designed as a locking pin 56, e.g. beveled, is located within the bore of the sleeve 57, so that the sash can be moved unhindered by the locking rod 55 in the direction of arrow ζ or Z ₂ , in that the rollers 84 and 85 can roll on the profile rail 86 forming the sliding guide 22.

If, however, the control rod 49 is _{lifted in the direction of arrow ^ 1} around the hub ₂ , the end of the locking rod 55 serving as the locking pin 56 comes into engagement with the bore 59 on the fixed frame or on the profile rail 86, so that the sash also at point B ( Fig. 1 and 3) is prevented from moving, but can pivot about the perpendicular axis AA determined by points B and D.
