Description

The invention relates to a window or the like, comprising a window frame, a sash frame and a tilt and turn fitting, with drive rod means arranged in the rebate area of the sash frame, which can be moved by manual actuation in the longitudinal direction of the respective sash frame leg in order to set the fitting into the functional positions TURNING, TILTING, LOCKING LATCHING to be able to, and further with a tilting display device arranged between the upper frame leg and the upper wing frame leg with a tilting arm, which is rotatably mounted on the frame around the axis of rotation of the wing frame, connected to the upper wing frame leg by a rotary slide connection and on the wing frame in parallel to that upper wing frame leg can be determined by mediating the drive rod means set in the functional position ROTATE, with the SPALTKIPP in an additional functional position adjustable drive rod means controlled gap tilt locking elements are provided to fix the casement in a gap tilt position between the closed position and the maximum tilt opening position.

Such a window is known from DE-A-24 51 556. In the known embodiment, the sash is fixed in a gap-tilt position between the closed position and the maximum tilt opening position in that a toothed locking rail is attached below the cuff rail of the upper sash leg penetrated by a rotating and sliding bolt of the extension arm, which is attached by the the drive rod associated with the upper wing frame leg can be pressed against the rotating and sliding bolt by means of lifting cams and is thus clamped to the faceplate in the area of the slot accommodating the rotating and sliding bolt.

The invention has for its object to enable a reliable determination of the size of the tilt opening gap in the gap tilt position, which is exerted by external forces on the sash frame, e.g. Wind power, regardless is preserved.

To solve this problem, various basic designs are proposed, all of which share the principle of solving that a first splitting tilt locking element movable by the connecting rod means and a second splitting tilt locking element in the functional position SPLIT TILT are adjacent to one another perpendicular to the frame level and in the functional position TILT perpendicular to the frame frame are movable against each other.

In a first basic design it is also provided that the second split tilt locking element is attached to the frame, the two split tilt locking elements are mutually adjustable in the direction of the respective drive rod, one of the split tilt locking elements is designed as a double cam guide element and the other as a cam follower, the cam follower in the functional position SPALTKIPP is defined between the two curves of the double curve guide element and in the TILT function position faces a recess area of the one curve.

Further developments of the first basic type result from claims 2 to 13.

The measure of claim 2 ensures simple handling of the window, so that in addition to the force exerted on the manual actuating means, no additional force effect on the casement in the direction perpendicular to the casement plane is necessary if the casement is to be brought from the closed position into the gap opening position and back.

The measure of claim 3 ensures a simplified stop and for an adjustability of the split tilt locking elements.

The measures of claim 6 provide for a twisted or twistable sash to maintain the gap width.

The measures of claims 7 to 9 are of particular importance. They ensure that the interacting gap tilt locking elements automatically adjust against each other when the sash is closed for the first time or again.

The measures of claims 11 and 12 ensure the right and left usability of the one designed as a double curve guide element tilt tilt locking element.

The measure of claim 13 ensures a smooth transition of the drive rod system into the functional position SPALTKIPP after closing the previously tilt-open sash frame.

In a second basic type (claim 14), in addition to the common solution principle, it is provided that the first split tilt locking element attached to the sash frame can be adjusted by the drive rod means in the plane of the sash frame between a ready to lock position occupied in the functional position SPALTKIPP of the drive rod means and a rest position and with a second split tilt locking element attached to the frame cooperates in such a way that after the first split tilt locking element has been set into the readiness for locking position in the following Approach of the sash frame to the gap tilt position, the two gap tilt locking elements gliding past one another in the tilting direction of the sash frame under pretension until they latch together after the gap tilt position of the sash frame is reached due to the pretension.

In a further basic design (claim 15), in addition to the common solution principle, it is provided that the second split tilt locking element is attached to the frame or part of the tilt tilting device and the first split tilt locking element transversely to the respective drive rod means in the sash plane from the drive rod means via a cam or Setting control between an inactive position in the SPALTKIPP function of the drive rod means and a non-ascertainable position in the functional position TILT of the drive rod means adjustable and in the active position the second split tilt detection element engages behind a curve guide element in the sense of preventing further tilting opening of the sash frame, and that a pair of guide elements further engage and a curve follower element is provided, one of these elements on the casement and adjustable by the drive rod means, the those of these elements on the window frame or on a part of the opening device movable when tilting transversely to the window frame plane, and the two elements of the pairing in such a mutual association that when the drive rod means are moved into the functional position SPALTKIPP an inevitable transfer of the casement frame into the gap tilt position occurs and in the Functional position SPALTKIPP the sash frame is secured against tilting by the pairing.

This third basic design can be developed by the measures of claims 16 to 29. Of particular interest is the design according to claim 23, which allows the split tilt locking elements to be accommodated in a central region of the upper wing frame leg without spatial collision with the conventional tilting tilting device.

The embodiment according to claim 30 allows relatively large gap opening widths without the dimensions of the fitting parts in the direction perpendicular to the window frame plane being significantly increased.

In a fourth basic design (claim 31) it is provided, in addition to the common basic principle, that the second split tilt locking element is attached to the frame, in particular the upper frame leg or the closure-side frame leg or a part of the opening device which is movable transversely to the frame level when the sash is tilted, the first When the sash frame is closed, the splitting tilt locking element can be moved in the longitudinal direction past the second splitting tilt locking element, the first and the second splitting tilt locking element in the functional position TILT when the sash frame is tilted transversely to the frame level, and the first split tilt locking element when the sash frame is set into position by adjusting the sash tilt Espagnolette means can be engaged from the functional position TILT to the functional position SPLIT TILT in engagement with the second split tipping locking element i st.

This basic design is particularly suitable to allow different different gap opening widths. Further developments of this fourth basic type are dealt with in claims 32 to 39. The measure of claim 32 is of particular importance here, precisely because of the possibility of enabling different gap opening widths. A particularly stable split tilt detection is achieved by the measure of claim 34. The measure of claim 35 ensures a large range of variation of the split tilt opening width.

The further development of claim 37 simplifies the handling of the window by forcing the casement at least approximately into the respective gap opening position by actuating the drive rod means before the gap tilt detection means are brought into effect.

The measures of claim 39 also ensure easy handling.

According to a fifth basic design (claim 40), in addition to the common functional principle, it is provided that the second split tilt locking element is arranged on a part of the opening device that is movable transversely to the frame level, and of two split tilt locking elements movable in the longitudinal direction of the connecting rod means relative to one another as a switching link next to an opening arm locking section and one Closing locking section has a gap-tilt locking section limited on both sides and an open tilt-opening section.

This basic design is characterized by the particular simplicity of the split tilt locking elements used and then by high functional reliability.

Further developments of the fifth basic type result from claims 41 to 53. The measure of claim 48 enables a relatively large gap opening width to be achieved without the dimensions of the fitting measured perpendicular to the frame level being significantly increased.

The measure of claim 51 receives its Significance in particular in that the sash frame is precisely set in the ROTATE function position regardless of the inaccuracies in the setting of the connecting rod system with respect to the opening arm and that the gap opening width is also precisely defined.

A sixth basic design (claim 54) provides, in addition to the measures of the common solution principle, that the first split tilt locking element with the drive rod means can be taken along part of their drive rod path by a lost motion connection, the first and the second split tilt locking element in the functional position TILT the sash frame transversely to the frame level pass each other and the first splitting device can be engaged when the casement is in the splitting position by moving the drive rod means from the functional position TILT to the functional position SPLIT-TIP after passing through the above-mentioned part of the driving rod path into engagement with the second splitting device.

This embodiment in turn creates the prerequisites for setting the gap opening width to different sizes without the gap tilt locking elements having to pass each other in the driving rod displacement direction.

The measures of claims 55 to 60 further develop the sixth basic type.

Claim 55 specifies a simple construction for the lost motion connection and claim 57 a construction in which the lost motion connection is essentially covered and therefore accommodated in a damage-resistant manner. The claim 58 ensures a particularly stable determination of the casement in the respective gap opening position.

Claims 61 and 62 give an idea of the size of the gap opening to be set, which is intended, for example, to provide adequate ventilation in an uninhabited room without excessive cooling or heating by the outside atmosphere.

The specification of claim 63 corresponds to the functional sequence frequently used in tilt-and-turn window construction, which can also be used in the design according to the invention and thus makes it easier for the customer to learn to use it.

The invention further relates to a tilt and turn fitting with the

In Fig. 1, the frame of a tilt and turn window is generally designated 10 and the casement generally designated 12. The casement is in the tilt opening position. The sash frame 12 is supported in a known manner by a corner bearing 14 and can be supported at 16 by a tilting bearing. There is an opening device 22 between the upper wing frame leg 18 and the upper frame leg 20. Drive rod means are arranged on the wing frame 12, at least on the upper wing frame leg 18 and on the wing frame leg 24 remote from the axis of rotation. These espagnolette means allow it by means of locking blocks, e.g. 28 to lock the casement 12 in the fully closed position. They also allow the tilting bearing to be switched to a tilting function at 16, so that the sash frame 12 can be tilted about the tilting axis 30, and they also allow an extension arm 32 of the opening device 22 by means of a fixing cam 34 and a cam engagement part 36 in parallel to that to fix the upper wing frame leg 18 so that the pivot bearing 38 of the extension arm 32 can take over the pivot bearing of the wing frame 12 about the axis of rotation 40 for the rotary opening operation. On the sash frame and the frame, fixing means 42 are provided for fixing the sash frame 12 in a gap-tilt position, in which the sash frame 12 is tilted only slightly and far less than in FIG. 1 about the tilt axis 30. As can be seen from FIG. 1, it is a fully concealed fitting, both the drive rod means 26 and the opening device 22 being accommodated in the rebate space between the frame and the sash. The depth of the rebate space accommodating the connecting rod means is indicated by h. In the gap opening position, the distance between the window frame visible surface and the stop surface 46 of the sash overturn should be of the order of magnitude h.

A manual control handle 48 is used to set the drive rod means in different functional positions. In Fig. 1, the manual control handle 48 is in the tilt ready position.

The various functional positions of the manual control handle 48 are indicated in FIG. 2: the position 48a corresponds to the locking locking position (closed), the position 48b corresponds to the ready-to-turn position (rotation), the position 48c corresponds to the gap-tilt position or gap-tilt ready position (gap-tilt) and position 48d (see also FIG. 1) corresponds to the readiness for tilting (tilting). The angular distance from 48a to 48b is 90 °, the angular distance from 48b to 48c is 45 ^. and the angular distance from 48c to 48d is again 45 °. There is therefore a switching path of 90 for the transition from the locking locking position 48a to the ready-to-turn position 48b ^. available, for the transition from the rotary opening position to the gap-tilt position or gap-tilt ready position, an additional switching path of 45 ° and for the transition from the switching-tilt or switching-tilt ready position to the tilt ready position, another switching path of 45 ^. to disposal. It is easily possible to enlarge the individual switching paths and thus the total switching path if the manual control handle 48 does not come into contact with the wall opening receiving the window. If this danger exists, the switching path can be increased, for example, by making the manual operating handle 48 foldable about a folding axis 50. If this happens, the total switching path of 180 ° can be run through twice without a collision with the boundary surfaces of the wall opening and the individual switching paths can then be doubled, for example.

In the switching position 48a, the locking block 28 and possibly further locking blocks are in engagement with striking plates (not shown) on the frame 10, so that the sash 12 is locked in its closed position on the frame. In the switching position 48b, the locking block 28 is released from the striking plate of the frame 10, not shown. The tilting bearing is also solved at 16. However, the locking cam 34 is in engagement with the cam engagement part 36 of the raising arm 32, so that the raising arm 32 is fixed to the upper wing frame leg 18 in a parallel position thereto and therefore the wing frame 12 by means of the raising arm 32 in the pivot bearing 38 is ready for rotation about the axis of rotation 40 defined by the corner bearing 14 and the pivot bearing 38.

In the tilt ready position 48d, the tilt bearing is in operation at 16, so that the wing frame men 12 can be tilted about the tilt axis 30 in the tilt opening position shown in FIG. 1. Here, of course, the locking block 28 is in turn released from the engagement with the associated striking plate on the frame 10 and also the locking cam 34 is out of engagement with the cam engagement part 36 of the deployment arm 32.

3 shows the opening device 22 and the associated parts of the drive rod means 26 to be attached to the upper wing frame leg 18. These drive rod means include a faceplate 52 inserted in a groove in the wing rebate, on the underside of which a drive rod 54 is guided. The drive rod 54 is connected via a corner deflection 56 in a movement-transmitting connection to a drive rod, which is likewise guided under a faceplate 60 on the casement leg 24 and which in turn is in a movement-transmitting connection to the manual operating handle 48.

The locking cam 34 is fastened to the drive rod 54 on the right / left and can be moved through an elongated hole in the faceplate 52 in connection with the drive rod 54. The cam engaging part 36, as can be seen in FIG. 3, can also be changed on the right / left of the extension arm 32 appropriate. The extension arm 32 is additionally articulated by an additional arm 62 to the faceplate 52 in a known manner. In order to fix the extension arm 22 to the upper casement leg 18, additional engagement means are provided in the vicinity of the pivot opening axis 40, namely an additional cam 64 and an additional engagement part 66, which are also designed to be right / left stop, i.e. Are arranged symmetrically to the longitudinal axes of the faceplate 52 and the extension arm 32. The additional cam 64 and the additional engagement part 66 are only in engagement in the locking locking position 48a and in the ready-to-turn position 48b and are otherwise detached from one another.

A double cam guide element 68, which is shown in detail in FIG. 4, is also attached to the drive rod 54 as part of the fixing means 42 which defines the gap-tilt position. This double cam guide element 68 is connected through an elongated hole in the faceplate to the drive rod 54 and is movable in the longitudinal direction with the drive rod 54. The double cam guide element 68 works together with a cam follower 70, which is arranged on the frame 10 in its rebate space in the longitudinal direction of the frame thigh 20 in an adjustable and lockable manner. The two guide curves of the double curve guide element 68 are designated 72 and 74. 4d, the double cam guide element 68 is in the tilt-ready position. The guide curve 74 has a central opening 76 so that the curve follower 70 and the guide curve 74 can be moved through and thus the sash frame 12 can move into the tilt opening position according to FIG. 1.

In Fig. 4c, the curve follower 70 is taken between the two curves 74 and 72, so that the sash is held in a gap-tilt position in which the distance of the stop surface 46 of the sash flap from the visible surface 44 of the frame is only very small, for example corresponds to the height h according to FIG. 1.

In the position of the double cam guide element 68 according to FIG. 4b and in the position according to FIG. 4a, the double cam guide element 68 is in each case out of engagement with the cam follower 70, so that the rotary opening of the sash frame 12 with respect to the frame 10 and the pressure of the sash frame 12 against the frame 10 are not hindered when locking.

When the manual control handle 48 is switched from the position 48a via the position 48b in the direction of the gap-tilt position 48c, a flank 72a of the curve 72 comes into engagement with the curve follower 70, so that the curve 72 is inevitably pressed in the direction of the arrow in FIG. 4b is and thus the sash 12 inevitably passes through the switching movement of the drive rod means in the gap-tilt position shown in FIG. 4c.

The symmetrical design of the double cam guide element 68 allows it to be implemented by rotating through 180 °, so that right / left usability is also ensured in this respect.

When switching back from the gap-tilt position according to FIG. 4c to the rotary position according to FIG. 4b, the curve follower 70 interacts with a flank 74a of the curve 74, so that the double curve guide element 68 is pressed against the frame in the arrow direction of FIG. 4c is, so that the transition from the gap-tilt position to the rotary position and the locking position and back can only be done by rotating action on the manual control handle 48 without additional force on the casement.

The additional cam 64 is opposite a support bar 78 in the gap-tilt position, so that in the gap-tilt position an approach of the casement 12 to the frame 10 using the casement, for example as a result of wind pressure from the inside, is not possible, although the locking means 42 is close the handle side of the casement are arranged; is thus through the engagement of the support bar 78 and the additional cam 64, the maintenance of a certain minimum gap width even when there is a risk of twisting the Sash frame guaranteed over the entire length of the sash frame thigh.

It must also be added that, with regard to the right / left usability of the opening device, it is necessary to make the opening arm 22 convertible about the axis 80 relative to the pivot bearing 38.

In the embodiment according to FIGS. 5 and 6, comparable parts are provided with the same reference numerals, increasing by the number 100. A lever 182 designed as a leaf spring is arranged on the housing of the corner deflection 156 and carries a first locking element 184 at its free end. This first locking element 184 works together with a second locking element 186, which is arranged on the frame 110 in the fold area. The leaf spring 182 has a central longitudinal slot 188, in the central area of which a control bridge 190 with rounded ends is provided. Provided on the movable spring band 192 of the corner drive 156 is a control cam 196 which extends through a slot 194 of the housing, which engages on the control bridge 190 in the gap-ready position shown in FIG. 5 and the leaf spring 182 against its spring action from the housing of the corner drive 156 lifts off in such a way that the first locking element 184 is applied to the second locking element 186 without pretension. 5 and the sash is tilted from the closed position about the tilt axis 30, the first locking member 184 slides with elastic deformation of the leaf spring 182 over the curved surface of the second locking member 186 to the first locking element 184 engages in the slot 198 of the second locking element 186 and thus fixes the gap tilting position, both against complete closing and against transfer in the direction of the normal tilting position according to FIG. 1.

In all other positions of the drive rod means, the control cam 196 extends through the slot 188 of the leaf spring 182, so that the leaf spring 182 bears against the housing of the corner drive 156 under its own spring action.

• An dem Gehäuse der Eckumlenkung 256 ist ein Kipphebel 217 kippbar gelagert. Die zur Flügelrahmenebene senkrechte Kippachse ist durch einen Lagerniet 219 definiert. Der Kipphebel 217 ist durch eine Blattfeder 221 in Richtung auf seine Ruhestellung vorgespannt. An dem freien Ende des Kipphebels 217 ist ein erstes Halteglied 223 angebracht. Dieses erste Halteglied 223 steht einem zweiten Halteglied 225 gegenüber, welches Teil des Schließbleches 211 ist. An einem mit dem Federband 292 verbundenen Treibstangenabschnitt 227 ist eine Steuerbrücke 229 im Bereich eines Langlochs 231 angeordnet. An dem Kipphebel 217 ist in dessen Längsrichtung verstellbar, ein Steuernocken 233 angebracht. Wenn sich der Schließkloben 213 der Spalt-Kippstellung 213c nähert, nähert sich die Steuerbrücke 229 dem Steuernocken 233, so daß nach Eintritt des Schließklobens 213 in die Spalt-Kippstellung 213c der Steuernocken 233 auf der Steuerbrücke 229 aufliegt und der Kipphebel 217 um seine Kippachse bei 219 im Gegenzeigersinn gegen die Wirkung der Feder 221 verschwenkt wird und das erste Halteglied 223 hinter das zweite Halteglied 225 eingreift. Damit ist in der Spalt-Kippstellung der Flügelrahmen gegen weitergehendes Öffnen in Richtung auf die normale Kippstellung gemäß Fig. 1 durch den Eingriff des ersten Halteglieds 223 und des zweiten Halteglieds 225 gesichert.

In the embodiment according to FIGS. 7 and 8, comparable parts are provided with the same reference numerals as in the embodiments according to FIGS. 1 to 4 and 5 and 6 each increased by the number 100 and 200, respectively. In the embodiment according to FIG. 7 and 8, the locking means 242, in deviation from the previously described embodiments, are arranged between the upper ends of the handle-side vertical legs of the casement frame and the frame 211, which cooperates with a locking piston 213. The locking block 213 is connected to the spring band 292 through an elongated hole in the corner deflection housing 256. 8 shows the locking block 213 in the closed locking position 213a, the ready-to-open rotary position 213b, the gap-tilt position 213c and the tilt-ready position 213d. When the locking block 213 is in the ready-to-open position 213b and is moved further downward by further pivoting of the manual control handle, it slides over a curve 215 of the locking plate 211, so that the sash is lifted off the frame. Thus, the gap-tilt position is determined by the curve 215 and the locking block 213 and the casement is prevented from moving into the fully closed position. The following measures serve to prevent the casement from being opened further in the tilt-and-tilt position in the direction of the normal tilting position:

• A rocker arm 217 is pivotably mounted on the housing of the corner drive 256. The tilt axis perpendicular to the sash frame plane is defined by a bearing rivet 219. The rocker arm 217 is biased by a leaf spring 221 towards its rest position. A first holding member 223 is attached to the free end of the rocker arm 217. This first holding member 223 is opposite a second holding member 225, which is part of the striking plate 211. A control bridge 229 is arranged in the region of an elongated hole 231 on a drive rod section 227 connected to the spring band 292. A control cam 233 is adjustable on the rocker arm 217 in its longitudinal direction. When the locking block 213 approaches the split-tilt position 213c, the control bridge 229 approaches the control cam 233, so that after the lock block 213 enters the split-tilt position 213c, the control cam 233 rests on the control bridge 229 and the rocker arm 217 about its tilt axis 219 is pivoted counterclockwise against the action of the spring 221 and the first holding member 223 engages behind the second holding member 225. Thus, in the gap-tilt position, the sash frame is secured against further opening in the direction of the normal tilt position according to FIG. 1 by the engagement of the first holding member 223 and the second holding member 225.

In all other positions of the drive rod means, the control cam 233 is out of engagement with the control bridge 229 in the region of the elongated hole 231, so that the functions locking lock, rotary opening and tilt opening are not hindered by the holding members 223 and 225.

The rocker arm 217 is secured by a guide pin 235 in the faceplate and in the part 227 against pivoting out of the wing plane chert.

It should also be added to the switching sequence that it would also be possible to provide the switching sequence that is normal for tilt-and-turn windows, closing locking, readiness to turn open, readiness to tilt and then to provide a functional position, readiness for tilting or tilting and tilting, to one end position, in particular to the ready position for tilt opening .

In Fig. 9, a frame is generally designated 2010 and a casement generally designated 2012. Compared to the frame 2010, the sash frame 2012 can be tilted about a tilt axis 2014 or rotatable about an axis of rotation 2016. For this purpose, a corner bearing (not shown in more detail) is provided in 2018, which allows both the tilting movement about the tilting axis 2014 and the rotating movement about the rotating axis 2016. A tilting bearing is also provided at 2020, which allows the tilting movement about the tilting axis 2014 and can be opened for the rotating movement about the rotating axis 2016. An opening device 2026 is provided between the upper leg 2022 of the frame 2010 and the upper leg 2024 of the sash 2012, which limits the tilt opening width of the sash relative to the frame 2010 to the position shown in FIG. 9 and which during the rotational movement of the sash 2012 by The axis of rotation 2016 on the thigh 2024 of the casement 2012 in a parallel position to it is determined by cooperating fastening bolts 2028 and 2030. The fastening bolt 2030, the tilting bearing 2020 and possibly other pairs of locking elements (not shown) for locking the casement 2012 on the frame 2010 are in through drive rod means 2032 controlled in a known manner.

To set a gap opening position, a pairing of a curve guiding element 2034 and a curve follower element 2036 is provided, the curve guiding element 2034 being arranged on the upper frame leg 2022 and the curve follower element 2036 being movably arranged in the longitudinal direction of the upper casement leg 2024 and being connected to the drive rod means 2032 for this purpose . The drive rod means 2032 are movable from a manual control handle 2038.

In FIG. 9, the manual actuation handle 2038 is switched to readiness for tilting and the sash frame 2012 is in the tilting position, and the switching position shown in FIGS. 10 and 11 is corresponding.

As can be seen from FIG. 10, the cam follower 2036 is designed as an oval locking pin which is fastened on a drive rod part 2032a and passes through an elongated hole 2039 of a faceplate 2040.

Fig. 10 also shows the design of the display device 2026 in detail; it comprises an extension arm 2042, which is rotatably mounted on the frame about the axis of rotation 2016 and is connected to the faceplate 2040 by a rotary slide connection 2044; it also includes an additional link 2046 which is articulated on the faceplate 2040 on the one hand at 2048 and on the extension arm 2042 on the other hand at 2050.

The drive rod part 2032a is movable in its longitudinal direction by moving the operating handle 2038.

The curve guide element 2034, which is doubled symmetrically about its vertical longitudinal center line for the purpose of right-left usability, comprises the first guide curve 2052 with sections 2052a, 2052b and 2952c and a second guide curve 2054 with guide curve sections 2054a and 2054b and a web 2056.

10, the curve follower element 2036 is in such a lateral position relative to the curve guide element 2034 that when the sash is tilted in the direction of the closed position, the curve follower element 2036 passes the right side of the web 2056 and against the first curve section 2052a of curve 2052 bumps. If, in this position, in which the sash frame is not fully closed and cannot be fully closed due to the bumping of the curve follower element 2036 on the curve section 2052a, the manual operating handle 2038 is pivoted from the ready-to-tilt position to the gap-tilted position according to FIG. 11, the curve follower element 2036 moves into the space between the web 2056 and the first curve section 2052a, so that in the gap-tilt position then reached, the window is opened by a small economy ventilation gap and can neither be opened nor closed completely.

The position of the tilt and tilt of the manual operating handle 2038 according to FIG. 11 is marked by a ball catch or the like.

If a ready-to-turn position is to be set starting from the gap opening position thus reached, the manual operating handle 2038 is rotated further into the ready-to-turn position according to FIG. 11, the cam follower element 2036 then reaching the area of the opening between the web 2056 and the end of the curve section 2054b, so that when the sash is rotated, the cam follower element 2036 can exit through this opening.

When the manual control handle 2038 finally comes out of the ready-to-turn position according to FIG. 11 is switched into the closing lock, the cam follower element 2036 moves further to the left, abuts the curve section 2054b of the curve 2054 and inevitably passes via this inclined curve section 2054b into the region of the horizontal curve section 2054a, so that it is between the two curve sections 2054a and 2052c is located and the casement is locked to the frame. When switching down, essentially the same processes take place in reverse, whereby when switching from the ready-to-turn position to the gap-tilting position, the cam follower element 2036 abuts the inclined curve section 2052b and is therefore inevitably entered into the space between the curve section 2052a and the web 2056, so that the casement inevitably comes into the gap opening position.

It can easily be seen that the functioning of the system and in particular the correct interaction of the cam guide element 2034 and the cam follower 2036 depends on the cam guide element 2034 being struck on the frame in a position corresponding exactly to the cam follower element 2036 on the drive rod 2032a. Such an exact mutual adjustment when the parts 2034 and 2036 are attached is, however, generally not to be expected in the window processing plants, which complicates the fact that in the window processing plants the building fittings have to be cut to the appropriate size for the respective window size and moreover that during the Reductions in the lifetime of a window are added which interfere with an adjustment once it has been made. To remedy this, the curve guiding element 2034 is attached to the upper frame leg 2022 so as to be displaceable in the longitudinal direction thereof, as indicated by the elongated holes 2058 and the double arrow 2060. For the purpose of self-adjustment of the cam guide part 2034, adjustment surfaces 2062a and 2062b are attached to them, which together form an adjustment funnel 2062. The adjusting funnel 2062 is so wide at its widened end that a funnel engagement bar 2064 attached to the faceplate 2040 in any case strikes the widened end of the funnel 2062 and, when further entering the narrowed funnel section, the guide element 2034 inevitably sets the correct position to the cam follower element 2036 . The fastening screws penetrating the elongated holes 2058 are always loosened so far or kept at a distance by spacer sleeves that the curve guiding element 2034 can be readjusted. The curve follower element 2036 is clearly defined in its area of movement by the elongated hole 2039 and is thus matched to the funnel engagement bar 2064.

This ensures that the cam follower element 2036 always finds its way into the cam guide element 2034 when the wing is closed and out of it when the wing is opened. Furthermore, it is ensured that when the cam follower element 2036 moves during its engagement with the cam guide element 2034, the cam follower element 2034 cannot be displaced, since the funnel 2062 is in engagement with the funnel engagement bar 2064.

As can be seen from FIG. 12, the curve guide part 2034 is designed in two parts for reasons of strength, the webs 2056 being formed on a sheet metal part which is screwed together with the zinc die-cast part during assembly or before.

FIGS. 13 and 13a show a tilting bearing, as can be provided at position 2018 in the tilt-and-turn window according to FIG. 9.

The tilting bearing comprises a tilting bearing plate 2070, which can also be produced as a zinc die-cast part, and which is attached to the vertical frame frame leg 2072, which is remote from the closure. This tilting bearing plate 2070 is opposed on the vertical wing frame leg 2074, which is remote from the lock, by a tilting bearing block 2076, which is fastened to a drive rod part 2032b and with its fastening foot 2078 penetrates an elongated hole 2080 of a faceplate 2082 combined with the drive rod 2032b to form a unit.

A lower tipping bearing pan 2084 is attached to the tipping bearing plate 2070, in which the tipping bearing block 2076 is in the tilt-ready position, the tipping bearing pan 2084 being designed such that it does not hinder the tipping of the casement.

Furthermore, a pivot opening 2086 is provided in the tilting bearing plate 2070, in the area of which the tilting bearing block 2076 is located when ready for rotation is switched on, so that the tilting bearing block 2076 can emerge from the area of the tilting bearing plate 2070. Finally, a locking lock receptacle 2088 is attached to the tilting bearing plate 2070, into which the tilting bearing block enters when the manual operating lever 2038 is brought into the locking locking position, the sash frame then also being pressed onto the frame in the area of the tilting bearing by corresponding inclined guide surfaces 2091.

Furthermore, a passage 2090 with insertion funnels 2090a and 2090b is attached to the tilting bearing plate 2070. In this passage 2090, depending on the type of stop, a funnel engagement bar 2092 enters through each of the funnels 2090a, 2090b, which, when it enters, the tilting bearing plate 2070 opposite the tilting bearing block 2076 adjusted, ie brings it into the correct target position. For this purpose, the tilting bearing plate 2070 is slidably attached to the frame leg 2072 through elongated holes 2094.

Self-adjustment also occurs here every time the casement is closed, since the tilting bearing plate 2070 is constantly displaceable.

14, a frame is generally designated 3010 and a casement 3012. The casement 3012 is tiltable relative to the frame 3010 about a tilt axis 3014 and rotatable about an axis of rotation 3016. An opening device is arranged between the upper frame leg 3018 and the upper wing frame leg 3020, which is generally designated 3022. This opening device 3022 comprises an opening arm 3024 which is rotatably mounted on the frame 3010 about the axis of rotation 3016 and is connected at 3026 to the upper casement leg 3020 by a rotary sliding guide. The opening device 3022 further comprises an additional link 3028 which is articulated at 3030 to the opening arm 3024 and at 3032 to the upper wing frame leg 3020.

At 3034 there is a permanently functioning corner bearing, which is used both for storage about the tilt axis 3014 and for storage about the axis of rotation 3016. At 3036 there is a tilting bearing which is closed only for the purpose of tilting opening and can be opened for the purpose of rotating opening.

For the rotating operation of the sash frame 3012 about the axis of rotation 3016, the extension arm 3024 is fixed to the sash frame 3012 in a parallel position to the sash frame leg 3020, in that a fixing bar 3038 of the sash frame 3012 engages behind a fixing bar 3040 on the opening arm 3024.

The displacement of the locking bar 3038, the opening and closing of the tilting bearing at 3036 and the establishment of the engagement of further locking bar pairs, not shown, between the sash frame 3012 and the frame 3010 is effected by drive rod means which are moved along the respective wing arm by a manual operating handle.

As far as described so far, the structure of the tilt and turn window is conventional.

An actuator 3046 movable with the associated drive rod is attached to the upper casement leg 3020 and a counter-actuator 3048 fixed to the frame to the upper frame leg 3018. These actuators 3046 and 3048 work together to define a tilt-tilt position of a relatively small gap opening width. The gap opening width is measured at the height of the upper frame legs, approximately less than 20 mm, preferably smaller than 10 mm, but can be larger up to the full tilt opening width shown in FIG. 14, the difference between the tilt opening and the gap tilt position then it also consists in the fact that the wing is secured against slamming into the closed position in the tilt-tilt position. The design of the actuators 3046 and 3048 is discussed in more detail below with reference to FIG. 15.

15, the extension arm 3024 is connected by the rotary slide connection 3026 to a faceplate 3050 which in turn is fastened to the upper casement leg 3020 and which serves to guide associated drive rod parts 3042a, the drive rod means 3042. The movable actuator 3046 is mounted on one of the drive rod parts 3042a. To the movable actuator 3046 in the area of the thickened toothed strip 3052 tooth notches 3054 are attached, which are intended to cooperate with an adjusting pin 3056 of the frame-fixed counter-actuator 3048.

In FIG. 15, the manual actuation handle 3044 and thus the movable actuator 3046 are switched to readiness for tilting and the sash frame is in the tilted position. It can be seen that the sash can be tilted completely back into the closed position from the tilted position according to FIG. 15, in which case the movable actuator 3046 can pass the actuating pin 3056 of the counter-actuator 3048. The state shown in FIG. 17c is then reached.

If the casement 3012 is closed according to FIG. 17c, the manual operating handle 3044 and accordingly the movable actuator 3046 can be moved into the position according to FIG. 17b with the casement remaining completely closed, i.e. 17c and 17b, as can be seen from the comparison of FIGS. 17c and 17b, the movable actuator 3046 with the thickened strip 3052 passes the actuating pin 3056 of the actuator 3048 fixed to the frame. 17b, as indicated by the rotating arrow, the sash frame can be pivoted about the axis of rotation 3016, in which case the thickened strip 3052 can again pass the actuating pin 3056.

Furthermore, with the sash frame 3012 remaining completely closed, the manual control handle can be pivoted from the position shown in FIG. 17b into the position shown in FIG. 17a, ie the locking position, whereby the movable actuator 3046 can in turn move freely through the frame 3048.

Conversely, of course, it is also possible to switch from FIG. 17a to 17b to 17c, the sash frame always being able to remain completely in the closed position with respect to the frame.

Starting from the ready-to-tilt position according to FIG. 17c, however, it is also possible to switch to the position according to FIG. 17d. For this it is necessary that the sash frame 3012 is first brought into the tilt-tilt position, i.e. is tilted a little bit about the tilt axis 3014 so that one of the tooth notches 3054 comes into alignment with the setting pin 3056. Then the manual actuation handle 3044 can be pivoted into the gap-tilt fixing position according to FIG. 17d until, as shown in FIG. 17d, one of the toothed notches 3054 abuts the actuating pin 3056 with its base. Now the manual control handle 3044 can no longer be pivoted further counterclockwise from the position reached in FIG. 17d.

If, starting from the position shown in FIG. 17c, the sash frame 3012 is tilted so far relative to the frame 3010 that when the manual operating handle 3044 is subsequently pivoted from the position shown in FIG. 17c into the position shown in FIG. 17d, the thickened strip 3052 no longer counteracts the Setting pin 3056 occurs but could pass it, as indicated in FIG. 15 by the dash-dotted drawing of the movable actuator 3046, a shift lock becomes effective, which is controlled by the movement of the additional link 3028 when the sash frame is tilted open. Such a shift lock is described in detail in German specification 26 58 626 and is shown in FIG. 18 insofar as is necessary for the understanding here. On the faceplate 3050 a lining part 3058 is fed, in which a locking pin is slidably guided. The locking pin 3060 passes through the faceplate 3050 and cooperates with its lower end with a locking groove 3062 in the drive rod part 3042d, while the upper end of the locking pin 3060 interacts with a segment-shaped control groove 3064. When the additional link 3028 is parallel to the faceplate 3050, the locking pin 3060 can be moved upward through the ends of the locking groove 3062 when the drive rod 3042a is moved and can penetrate into the control groove 3064, so that the movement of the drive rod part 3042a is unimpeded. When the position is reached, which is indicated in Fig. 15 by the dash-dotted position of the movable actuator 3046 relative to the frame-fixed actuator 3048, the upper end of the locking pin 3060 is outside the area of the segment-shaped control groove 3064, so that the locking pin 3060 does not can dodge more and thus the movement of the drive rod means 3042 is blocked.

It should also be noted that, with regard to right-left usability, the actuator 3048 on the frame side is provided with a further actuating pin 3056a and the movable actuator 3046 can be screwed onto the associated drive rod part 3042a in two different positions.

It can be easily seen that in the absence of actuators 3046 and 3048, the fitting described so far works as a pure tilt-and-turn fitting without a gap-tilt position and that it is therefore also easily possible to convert the fitting to additional gap-tilting function by retrofitting actuators 3046 and 3048. It can be seen from Fig. 16 that in the split tilt fixing position the actuating handle is approximately in a position between the readiness to tilt position and the ready to turn position. This split tilt fixing position of the actuating handle 3044 is basically defined by the stop of the setting pin 3056 of one of the tooth notches 3054, so that no special latching on the manual actuating handle 3044 is required to make the split tilt tilt fixing position perceptible. Switching from readiness to tilt to split tilt fixation is completely "foolproof"; because either one of the positions is reached by tilting the wing, in which one of the notches 3054 slides over the setting pin 3056 or it is tilted further, then the manual control handle 3044 cannot be turned counterclockwise because of the shift lock, so that the operator can immediately recognize from the coming into effect of the shift lock that it has opened too much to be able to bring about a gap tilting position and must accordingly tilt back again towards the closed position of the casement.

As can be seen from FIG. 17e, it is also possible to set and fix a rotary gap. 17b, in which the casement is closed and the manual control handle 3044 is in the ready-to-turn position. It can be seen from Fig. 17b that the casement can be opened for rotation, whereby the thickened strip 3052 can pass between the adjusting pins 3056 and 3056a. If one of the tooth notches 3054 is in alignment with the actuating pin 3056a, the manual operating handle 3044 is brought into the position according to FIG. 17e, the one notch 3054 sliding over the actuating pin 3056a, so that the split rotational position of the casement is fixed. It can be seen from Fig. 17e that the manual operating handle 3044 is in a further 45 position between the locking position and the ready to turn position. This position is also fixed by the engagement of the setting pin 3056a and the tooth notch 3054.

17f again shows the casement in the split rotation position. Now, however, the thickened toothed strip 3052 'has been designed differently, so that it has additional tooth notches 3054'. The position of the casement according to FIG. 17f is again reached starting from the position according to FIG. 17b, but the manual operating handle 3044 is brought into a position below 45 corresponding to FIG. 17d, the adjusting pin 3056 then engaging with a tooth notch 3054 ' occurs.

In the embodiment according to FIGS. 19 to 22, the same parts are provided with the same reference symbols as in the embodiment according to FIGS. 14 to 18. Analog parts are provided with the same reference symbols, in each case increased by the number 100.

19 again shows a movable actuator 3146, which is designed with an adjusting web 3146a. The counter actuator 3148 is designed in the form of a tooth segment which is designed with a plurality of tooth notches 3166 and is located at the end of the additional link 3128.

19 and 20, the manual operating handle 3044 and thus the actuator 3146 are switched to readiness for tilting and the wing is brought into the tilted position.

If the sash is to be brought into the closed position from the tilted position according to FIG. 19, the adjusting web 3146a passes the toothed segment 3148, as is readily apparent from FIG. 19. If the manual operating handle 3044 is then brought into the ready-to-turn position according to FIG. 21 with the sash frame completely in the closed position, the adjusting web 3146a runs along the edge of the additional link 3128 facing away from the overturning of the wing without the adjusting web 3146a and the additional link 3128 mutually moving hinder. Even if the closing locking position (not shown) of the movable actuator 3146 is reached, the adjusting web 3146a still bears against the edge 3128a of the additional link 3128. In the ready-to-turn position, the positioning web 3146a of the additional link 3128 secures in the parallel position corresponding to the readiness to turn on the sash flap.

19, however, if the sash frame is to be brought from the tilt opening position according to FIG. 19 into the tilt-tilt position and fixed, the sash frame 3012 is first tilted in the direction of the closed position until the left end of the adjusting web 3146a in FIG. 19 is opposite one of the tooth notches 3166. If the manual actuation handle 3044 is then pivoted from the ready-to-tilt position according to FIG. 30 into the gap-tilt fixing position, the web 3146a engages with its left end in the respective tooth notch 3166, so that a gap-tilting position is defined and the handle 3044 does not extend beyond the 45th gap-tilt fixing position 20 can be pivoted towards the ready-to-turn position. The relative position of the additional link 3128 and the movable actuator 3146 in the gap tilt position or gap tilt fixing position is shown in FIG. 22.

This embodiment, like the embodiment described with reference to FIGS. 14 to 18, can cooperate with a shift lock.

FIG. 23 shows another embodiment of the additional link 3228 in a further development of the design according to FIGS. 19 to 22. The toothed segment 3248 is broadened so that even more gap tilt positions can be set; Under certain circumstances, the largest gap tilt opening width can correspond to the tilt opening width that is specified by the opening device 3022. In these circumstances, a shift lock is no longer absolutely necessary.

However, it should be noted that the embodiment of FIG. 23 requires a relatively large fold depth in the direction perpendicular to the frame level or a recess in the flap of the casement.

The embodiment according to FIGS. 19 to 22 can also be offered as a retrofit version. It is only necessary to provide an additional link 3128 with a toothed segment 3148 as standard and the actuator 3146 can then be provided as a retrofit part. The embodiments according to FIGS. 19 to 23 can also be used right-left. In the case of the embodiment according to FIGS. 19 to 22, only the movable actuator 3146 needs to be rotated by 180 ′. In the case of the embodiment in FIG. 23, the additional link 3228 must also be turned.

It should also be noted that in all embodiments the usual switching sequence locking lock - ready to turn - readiness to tip remains.

All of the embodiments are particularly cost-effective since they have been developed from the usual turn-tilt fittings and can be created practically without or only with a small number of additional parts. In the embodiment according to FIGS. 19 to 22 there is a further advantage that a large degree of independence from cutting accuracy is important when adapting the respective fitting a certain window size and also a large degree of independence from the sash adjustment is achieved.

Regarding the embodiment according to FIGS. 14 to 18, it must also be added that several pairings of one movable and one frame-fixed actuator are possible, e.g. on the two vertical pairs of legs, especially for large-format windows. A combination of the embodiment according to FIGS. 14 to 18 on the one hand and an embodiment according to FIGS. 19 to 22 or 23 on the other hand is also conceivable.

24, the frame of the tilt and turn window is generally designated 4010 and the casement 4012. The casement is rotatable about an axis of rotation 4014 and tiltable about a tilt axis 4016. A corner bearing is provided at 4018 in the lower right-hand corner of the wing, which permits tilting about the tilt axis 4016 as well as turning about the axis of rotation 4014. A tilting bearing is provided in the lower left wing corner at 4020, which is closed when tilting and can be released for the purpose of rotating the wing frame about the axis of rotation 4014. An opening device 4026 is provided between the upper frame leg 4022 and the upper casement leg 4024. This opening device comprises an opening arm 4028 which is rotatably mounted in a pivot bearing 4030 on the frame 4010 about the axis of rotation 4014 and is rotatably and displaceably guided with its other end in a pivoting slide guide 4032 on the upper casement leg 4024. The opening device 4026 further comprises an additional link 4034, which is connected in an articulated manner to the opening arm 4028 by means of a connecting pin 4036 and is connected in an articulated manner by means of a connecting pin 4038 to a cuff rail 4040 which is laid in the rebate space of the upper casement leg 4024 and arranged with one below it Driving rod forms a structural unit. The drive rod is equipped with an opening device locking element 4042, which interacts with an opening device counter-locking element 4044 on the opening arm 4028. Also arranged in the vertical wing frame leg 4046, which is remote from the axis of rotation, is a faceplate drive rod assembly, the drive rod of which is equipped with a locking element 4048 for cooperation with a counter-locking element (not shown) on the vertical frame leg 4050. The drive rods can be moved from a manual operating handle 4052 in the longitudinal direction of the respective wing frame leg. 24, the manual control handle 4052 is shown in the tilt ready position. The manual control handle 4052 can be brought into the positions indicated in the figure sketch for FIG. 24. Position 1 represents the readiness to tilt; position 11 represents the gap tilt ready position; position 111 represents a ready-to-turn position and position IV represents a locking locking position.

In functional position I, the drive rod of the upper wing frame leg 4024 is on the far left and the drive rod of the vertical wing frame leg 4046 is at the bottom.

In the functional position 111, the ready-to-turn position, the upper horizontal drive rod is shifted somewhat to the right, the vertical drive rod of the casement leg 4046 is shifted upward. Locking member 4048 is still out of engagement with the associated counter-locking member. The opening device locking element 4042, however, now engages behind the opening device counter locking element 4044 when the opening arm 4028 is positioned parallel to the upper casement leg 4024, so that the pivot bearing 4030 of the opening arm 4028 forms a pivot bearing for the pivot mounting of the leaf frame 4012 about the axis of rotation 4014.

In the functional position IV, the closed locking position, the locking element 4048 has come into engagement with the counter-locking element on the vertical frame leg 4050 when the sash frame 4012 is closed, so that the sash frame 4012 is locked in the closed position on the frame 4010, the opening device locking element 4042 still being engaged with the display device counter-locking element 4044. The tilting bearing is closed in the functional position I and is released at least in the functional position 111.

• einen Kippöffnungsabschnitt 40621, einen Spaltkippfeststellabschnitt 406211, einen Ausstellarmfeststellabschnitt 4062111 und einen Schließverriegelungsabschnitt 40621V.

The representation of the opening device 4026 in FIGS. 25 and 26 corresponds to the state of the window according to FIG. 24. A drive rod 4056 of the upper horizontal casement leg 4024 can be seen in FIG. 25. On this drive rod 4056 there is a splitter tilt locking element in the form of a round pin 4058 on the drive rod side attached, which passes through an elongated hole 4054 of the faceplate 4040. This splitting tilt locking element 4058 on the drive rod side interacts with a splitting tilt locking element 4060 on the extension arm side in the form of a link plate with a switching link 4062. The switching gate 4062 has the following sections:

• a tilt opening section 40621, a split tilt detection section 406211, a deployment arm detection section 4062111 and a locking latch section 40621V.

If the manual actuation handle 4052 is in the switching position I, then the splitting tilt locking element 4058 is located on the connecting rod side in the area of the tilt opening section 4062 I, so that a tilt opening of the casement 4012 is possible until the opening arm 4028 has reached the end of the rotary slide guide 4032. In this tilted position, the sash frame is only secured against returning to the closed position by its own weight and by friction. If the casement 4012 is tilted back in the direction of the closed position, complete closure is not possible, since the splitting and tilting locking element 4058 on the connecting rod side previously abuts the shift link 4062 in the region of the tilting opening section 4062 I. Starting from this position, the manual operating handle 4052 can then be shifted further into the switching position II, the split tilt ready position, the splitting tilt locking element 4058 on the connecting rod side reaching the area of the split tilt locking section 4062 11 of the switching link 4062, so that the sash tilt 4012 is now held in its tilt tilt position in both tilting directions is. This position is shown in Fig. 27. In the exemplary embodiment, the gap tilt opening width therefore corresponds - but not necessarily - to the position in which the sash frame is in the tilt ready position when the splitting tilt locking element 4058 on the drive rod side enters the switching link 4062 through the tilt opening section 40621 and strikes the rear edge of the tilt opening section 4062 I.

Switching from the ready-to-tilt position II to the ready-to-rotate position 111, which is shown in FIG. 28. The splitting and tipping locking element 4058 on the connecting rod side enters the opening arm locking section 4062 III of the switching link 4062, the opening arm 4028 being approximated to the sash overlap 4064 of the sash frame 4012 and being secured in an approximately parallel position to the latter. During this switching operation, the opening device locking element 4042 also enters the opening device counter locking element 4044, so that the opening arm 4028 is also fixed on the sash frame 4012 in the vicinity of the axis of rotation. In this respect, one can speak of a progressive suit, because the splitting and tipping locking element 4058 on the connecting rod side first enters the switching link 4062 and only later the opening device locking element 4042 on the connecting rod side extends into the counter arm locking element 4044 on the opening arm side.

From this position, when the casement is in the closed position, it is possible to advance to the closed locking position, which is shown in FIG. 29. In this position, the drive rod-side split tilt locking element 4058 is located in the region of the locking locking section 4062 IV of the switching link 4062 and the opening device locking element 4042 is still in engagement with the slot of the opening device counter locking element 4044.

It should be noted that the opening device is intended for both right and left stop and also the drive rod cover rail assembly 4056, 4040. The right-left changeover can be carried out, for example, in such a way that the extension arm 4028 is one to the pivot bearing bracket 4028a carrying it Longitudinal extension of the arm 4028 parallel axis is rotated or implemented by 180 °.

With regard to the right-left convertibility, the opening device locking elements 4042 and 4044 are designed and arranged symmetrically. The drive rod-side split tilt locking element 4058 is also arranged in the example in the longitudinal center of the drive rod, so that the right-left changeover is unproblematic. However, the asymmetrical tilt arm locking element 4060 on the side of the extension arm must be turned through 180 ° for the purpose of right-left changeover, so that for this reason it is detachably attached to the opening arm 4028.

If it turns out to be necessary with regard to an early tightening, the splitting and tipping locking element 4058 on the connecting rod side is arranged outside the longitudinal center of the connecting rod, then an implementation in the case of the right-left conversion is also necessary.

The tilt arm locking element 4060 on the extension arm side can also be adjustably mounted on the opening arm 4028 for the purpose of changing the suit perpendicular to the window plane, as will be described in detail in connection with the modified embodiment of FIG. 31.

The embodiment of FIG. 30 largely corresponds to the embodiment of FIGS. 24 to 29. The only difference lies in a change in the shift sequence and a corresponding change in the shape of the shift gate.

Parts with the same function are provided with the same reference symbols, each increased by the number 100.

The changed switching sequence is shown in the accompanying figure for FIG. 30. The manual control handle 4052 is in the ready-to-tilt position II 'at an angular distance of approximately 45 ° from the ready-to-tilt position I. Then the drive-rod-side locking device 4158 is located in the section 416211' according to FIG. 30. This embodiment has the advantage that a larger switching path overall is available and that the switching sequence I, 111, IV of the classic switching for turn-tilt windows corresponds.

It should be noted in the embodiment according to FIG. 30 that the tilt-arm locking element 4160 on the extension arm side is in this case attached in the vicinity of the axis of rotation, so that it is possible to dispense with additional locking device locking elements. Of course, also in Fig. 30, the split tilt locking element 4160 can be attached in the same position as the element 4060 in the embodiment according to Figs. 24 to 29 and an additional opening device locking element can then be provided in the vicinity of the axis of rotation, so that again a progressive suit is guaranteed.

30 shows a slight inclination of the link section 41621V with respect to the window plane, as a result of which an additional tightening when switching from the ready-to-turn position 111 to the locking position IV can be achieved.

It should also be noted that it is of course also possible to provide the switching link directly in the opening arm 4028.

Furthermore, it is possible to attach the shift gate to the additional link 4034 as shown in FIG. 26, whereby either a separately mounted gap tilt locking element 4060 is used here or the shift link 4062 can be worked directly into the additional link 4034.

In the case of the embodiment according to FIGS. 24 to 29, it is recommended to mark at least position II of the manual control handle 4052 by means of a catch. In the case of FIG. 30, this is also possible, but not necessary.

In the embodiment according to FIG. 31 the switching sequence again applies as in the embodiment according to FIGS. 24 to 29. The extension 4263 has a different purpose here in connection with two eccentric arrangements 4266 and 4268. The eccentric arrangement 4268 comprises one eccentric 4268a and one elongated hole 4268b extending transversely to the window plane. The eccentric arrangement 4266 comprises an eccentric 4266a and an elongated hole 4266b which extends parallel to the window plane. The eccentric arrangement 4268 serves to adjust the split tilt locking element 4260 parallel to the window plane, while the eccentric arrangement 4266 serves to adjust the split tilt locking element 4260 perpendicular to the window plane. Since the two eccentric arrangements 4266 and 4268 are not sufficient to fix the split-tilt window element 4260 to the opening arm 4028 without movement, a pin 4265 attached to the opening arm 4028 engages in the elongated hole 4263, this engagement not impairing the adjustability by the eccentric arrangements 4266 and 4268 becomes.

A further embodiment is shown in FIGS. 32 to 34, again in the direction of arrow XXXVI in FIG. 25.

Analog parts are provided with the same reference numerals, each increased by the number 300.

The ready-to-turn position can be seen in FIG. 32, the ready-to-tilt position in FIG. 33 and the split-tilt fixing position in FIG. 34.

The embodiment according to FIGS. 32 to 34 differs from the embodiment according to FIGS. 24 to 29 by a different design of the splitting and tilting locking elements 4358 and 4360 on the push rod side and on the opening device side.

In addition, a gap tilt opening cam 4380 is provided in the embodiment according to FIGS. 32 to 34.

In the ready-to-turn position according to FIG. 32, the splitting and tipping locking element 4358 on the connecting rod side engages behind the splitting and tilting locking element 4360 on the side of the opening device in the sense of fixing the opening device on the wing overlap 4364 essentially parallel to the wing plane. If the sash is switched from the ready-to-turn position according to FIG. 32 to the ready-to-tilt position according to FIG. 33 with the sash frame closed, the left end in FIG. 33 of the splitting-tilt locking element 4358 on the push rod side abuts against the cam 4380, which is arranged on the opening arm 4328, so that the Display device 4326 and thus the casement 4312 is forced into the gap tilt opening position shown in FIG. 33, which is indicated by the tilt opening gap A. This tilt opening gap is so small that no significant moment of gravity acts in the sense of a further tilt opening of the sash frame on the sash frame, and the sash frame thus remains at least briefly in the gap tilt opening position according to FIG. 33 because of the inevitable friction, in particular in the opening device. Then, when switching back to the splitting tilt fixing position according to FIG. 34, the splitting tilt locking element 4358 on the connecting rod side engages with its tooth 4358a in the tooth space 4360a of the splitting tilt locking element 4360 on the side of the exhibitor device, with a slight correction of the tilt opening gap of the dimension A in FIG. 33 possibly being added to this Dimension A 'according to FIG. 34 can occur.

This method of operation is of particular ergonomic interest: the user, if he has switched to the ready-to-tilt position, in any case reaches the open-close position A at least approximately, so that he can then decide whether he wants to open the window further into an open position (not shown), which one due to the rotating sliding guide of the opening arm on the sash 33 is determined or whether he wants to fix the gap tilt opening position reached by switching back from the switching position tilt readiness according to FIG. 33 to the switching position tilt tilt fixing, and thus wants to fix the gap opening tilt gap A 'that has already been reached.

It is conceivable that several teeth or tooth gaps are now possibly attached to the gap tilt locking elements 4358 and 4360. A pairing of tooth and tooth space will then be arranged such that after reaching the gap tilt opening position according to FIG. 33 they will necessarily find one another when shifting into the gap tilt fixing position according to FIG. 34. Additional pairings of teeth and tooth gaps can then be brought about by additional tipping force on the sash frame and then fixed.

Of course, right-left usability is also sought in the embodiment according to FIGS. 32 to 34, so that the gap-tilt opening cam 4380 can also be converted.

In Fig. 35 the frame of a tilt and turn window is generally designated 6010 and the casement generally 6012. The casement is in the tilt opening position. The sash frame 6012 is supported in a known manner by a corner bearing 6014 and can be supported by a tilting bearing at 6016. There is an opening device (scissors) 6022 between the upper casement leg 6018 and the upper frame leg 6020. Drive rod means are arranged on the casement 6012, at least on the upper casement leg 6018 and on the casement leg 6024 remote from the axis of rotation. These espagnolette means allow it by means of locking blocks, e.g. 6028 to lock the sash 6012 in the fully closed position. They also allow the tilting bearing to be switched to a tilting function at 6016, so that the sash 6012 can be tilted about the tilting axis 6030, and they also allow an extension arm 6032 of the opening device 6022 by means of a locking cam 6034 and a cam engagement part 6036 in parallel to that to fix the upper wing frame leg 6018, so that the pivot bearing 6038 of the extension arm 6032 can take over the pivot bearing of the wing frame 6012 about the axis of rotation 6040 for the rotary opening operation. As can be seen from FIG. 35, it is a fully concealed fitting, both the drive rod means 6026 and the opening device 6022 being accommodated in the rebate space between the frame and the sash. The depth of the rebate space accommodating the connecting rod means is indicated by h. In the gap opening position, the distance between the window frame visible surface 6044 and the stop surface 6046 of the sash overturn should be of the order of magnitude h.

A manual operating handle 6048 is used to set the drive rod means in different functional positions. In Fig. 35, the manual operating handle 6048 is in the tilt ready position.

36, 37, 38, 40 and 41, a faceplate of the sash upper leg is designated by 6049. A drive rod 6050 is slidably guided on the inside of this faceplate. The extension arm 6032 is rotatably supported at its right end in FIG. 36 on the rotary bearing 6038 about the axis of rotation 6040 and at its left end in FIG. 36, as can be seen in FIG. 35, is rotatable and displaceable in a rotary slide guide 6051 on the faceplate 6049 guided. An additional link 6052 is hinged at one end to the faceplate 6049 and at the other end to the extension arm 6032. In the parallel position of the extension arm 6032 to the sash upper leg 6018, this additional link 6052 takes over the fixing of the sash frame 6012 in its longitudinal direction.

The faceplate 6049 has an opening 6053. This opening 6053 is penetrated by a first holding member 6055 which is movable in the direction of the double arrow 6054. A second U-shaped holding member 6056 with two mutually parallel flanges 6056a and 6056b is fastened to the extension arm 6032. 30, the first holding member 6055 is drawn in its lowermost position, in which it is disengaged from the second holding member 6056. This is the tilt ready position, which corresponds to the functional position I of the handle 6048. In this position the window can be tilted until the extension arm 6032 comes to a stop at the end of the rotary slide guide 6051.

37 shows a gap tilt opening position. The handle 6048 is in the gap tilt opening position labeled II. The locking cam 6034 bears against a cam guide element 6057, which in turn is attached to the extension arm 6032. This ensures that the casement cannot be tilted back into the closed position from the gap tilt opening position shown in FIGS. 37 and 38. On the other hand, the first holding member 6055 engages between the flanges 6056a and 6056b and lies against the flange 6056b, so that the sash cannot be tilted further from the position of FIGS. 37 and 38. The position of the flange 6056b on the extension arm 6032, and the position of the cam guide element 6057 on the extension arm on the other hand, are so taking into account the position and dimensions of the holding member 6055 and the fixing cam 6034 chosen that the thigh 6018 of the casement 6012 in the gap tilt opening position shown in FIGS. 37 and 38 is approximately parallel to the thigh 6020 of the frame 6010.

40, the first holding member 6055 is still inserted between the flanges 6056a and 6056b of the second holding member 6056, and the locking cam 6034 is inserted between the two legs 6036a and 6036b of the cam engagement part 6036, so that the sash frame 6012 is set in parallel to the extension arm 6032.

41, the locking cam 6034 still engages between the legs of the cam engaging portion 6036 and the first retainer 6055 engages between the flanges 6056a and 6056b of the second retainer 6056.

40 and the gap tilt opening position according to FIGS. 37 and 38, the setting cam 6034 runs with its tapered left end edge 6034a against the inclined surface 6057a of the cam guide element 6057, so that the sash frame in the gap tilt opening position according to FIG. 52 is pushed, wherein a further tilting opening of the casement is prevented by the first holding member 6055 resting on the flange 6056b of the second holding member 6056.

37 and 52 is switched to the ready-to-tilt position according to FIG. 36, the setting cam 6034 moves along the edge 6057b of the curve guiding element 6057, and the first holding member 6055 becomes from the space between the flanges 6056a and 6056b retracted downward, so that after reaching the tilting ready position according to FIG. 36, the sash frame 6012 can be tilted back into the fully tilted position according to FIG. 35.

At this point, the following should only be mentioned for the sake of completeness: in the ready-to-tilt position according to FIG. 36 and in the tilt-open position according to FIGS. 37 and 38, the tilt bearing is engaged at 6016, so that the sash frame 6012 can tilt about the tilt axis 6030.

40, the clutch is open at 6016, so that the sash 6012 can be rotated about the axis of rotation 6040.

In the closed locking position according to FIG. 41, locking elements on the casement and on the frame are engaged in order to secure the casement on the frame.

For moving the first holding member 6055 up and down in the direction of the double arrow 6054 of FIG. 36, a shaped piece 6058 is fastened to the drive rod 6050. This fitting 6058 is received with an upper collar 6059 from an elongated hole 6060 in the drive rod 6050. The shaped piece 6058 itself has an elongated hole 6061, which is delimited by two link walls 6062 and 6063. On the backdrop walls 6062, 6063, backdrop tracks 6062a, 6063a are formed which, as can be seen from FIGS. 42 and 43, are open at the top in their left part and covered by the faceplate 6049, while in their right parts they are within the backdrop walls 6062 or 6063 run. The first holding member 6055 engages between the link walls 6062 and 6063. A cross pin 6064 is fastened to the first holding member 6055, one end of which engages in the slide track 6062a and the other in the slide track 6063a.

36 (readiness for tilting), the ends of the transverse pin 6064 are in the right part of the link tracks 6062a, 6063a according to FIGS. 42 and 43, so that the first holding member 6055 is lowered into the position according to FIG. 36. If the drive rod 6050 is shifted from the tilt ready position I according to FIG. 36 into the gap tilt opening position 11 according to FIGS. 37 and 38, the ends of the transverse pin 6064 reach the area on the left in FIGS. 42 and 43 of the link guide tracks 6062a and 6063a, i.e. between the top edges of the walls 6062, 6063 and the faceplate 6049 with the result that the first holding member 6055 is raised as shown in Fig. 37 and engages between the flanges 6056a and 6056b. In this position, the holding member 6055 remains when switching to the ready-to-turn position 111 according to FIG. 40 and the locking position IV according to FIG. 41.

The fitting 6058 is fastened to the drive rod 6050 by rivets 6065.

In the embodiment according to FIG. 44, analog parts are provided with the same reference numerals as in the embodiment according to FIGS. 36 to 43, each increased by the number 100.

In contrast to the embodiment according to FIGS. 36 to 43, in the embodiment according to FIG. 44 the opening 6153 is delimited by two tabs 6153a, 6153b which were created when the opening 6153 was punched out.

In a further deviation from the embodiment according to FIGS. 36 to 43, the first holding member 6155 in the embodiment according to FIG. 44 engages in the additional link 6152. For this purpose, a plate is doubled on the underside of the additional link 6152 as a second holding member 6156, which has a cutout 6156a for the engagement of the first holding member 6155. The cutout 6156a is dimensioned approximately as the distance between the flanges 6056a and 6056b in FIG. 38, so that the first stop member 6155 rests on one boundary edge when the stop is at the right in the gap tilt opening position and on the other boundary edge when the stop is to the left. Otherwise, the embodiment according to FIG. 44 corresponds to the embodiment according to FIGS. 36 to 43.

In the embodiment according to FIGS. 45 to 49, the parts defining the gap tilt opening position are arranged in the region which is delimited by dash-dotted lines in FIG. 35 and is designated by LIX, LX.

45 shows a faceplate 6266 and a drive rod 6267 guided on it. A locking block 6228 is attached to the drive rod 6267 and is intended for engagement with a locker 6268. Furthermore, a shaped piece 6258 is fastened to the drive rod 6267 and is partially received by an elongated hole 6260 of the drive rod 6267. The shaped piece 6258 has two link walls 6262 and 6263, which define an elongated hole 6261 between them. The first holding member 6255 is received in the elongated hole 6261. The ends of the cross pin 6264 of this first holding member 6255 are guided in shift link tracks 6262a, 6263a. The shift gate tracks 6262a and 6263a are partially designed as slots through the respective backdrop wall and partially as grooves that are open to the elongated hole 6261, namely that each groove section of the one backdrop wall faces a continuous slot section in the other backdrop wall, so that the shift gate tracks 6262a, 6263a can be produced by a end mill or a die-casting tool, and yet a sufficient mechanical cohesion between the parts on both sides of the shift gate tracks is ensured. It can be seen from FIG. 45 that the first holding member 6255 is extended to the left out of the faceplate 6266 only in the gap tilt opening functional position, while it is retracted to the right in all other functional positions. Therefore, the shift gate tracks are designed in two stages.

46 shows the various functional settings of the locking locking block 6228 compared to the locking locking plate 6268, while in FIG. 45 the references to the various functional positions are intended to indicate which parts of the shifting gate tracks, which, in contrast to the embodiment according to FIGS. 35 to 44, are designed in two stages Function position, take up the cross pin 6264. In the gap-tilt opening position, the first holding member 6255 engages behind a second holding member 6256, which is fastened to the striking plate 6268. The engagement of the holding members 6255 and 6256 secures the sash frame against further opening, while preventing it from being closed further by the closing locking block 6228 resting against the edge 6268a of the Locking plate 6268 is secured.

When the connecting rod means are transferred from the ready-to-turn position to the gap-tilt opening position, the sash frame is automatically moved into the gap-tilt opening position by the interaction of the locking block 6228 with the edge 6268a, and the holding element 6255 is inevitably retracted behind the second holding element 6256. From Fig. 46 it can be seen that the locking plate 6268 is doubled in mirror image, so that this can also be used for right and left stop. The assembly 6266, 6267 with the shaped piece 6258 and the first holding member 6255 can also be used for right and left stop, thanks to the mirror image with respect to a longitudinal center plane parallel to the drawing plane.

It can be seen without further ado that the arrangement according to FIGS. 45 to 49 can alone define the gap tilt opening position, in which case a simple conventional opening scissors can be used. However, it is also possible to use an embodiment according to FIGS. 45 to 49 in combination with an arrangement according to FIGS. 36 to 43 or in combination with an arrangement according to FIG. 44.

45 to 49, an arrangement of the holding members 6255, 6256 according to the invention in the region of the transmission housing at 6048 or in the vicinity thereof is also conceivable. With such a configuration on a tilt and turn window, it is advantageous that in the area of the gearbox only about half a gap dimension, for example 5 mm, is necessary in order to obtain the desired gap dimension, for example 10 mm, on the thighs 6018, 6020. In the case of larger gap dimensions, the holding members in the area of the thigh can only be arranged with particular effort in view of the lack of space in the fold. A larger gap dimension than about 10 mm is particularly necessary if there are seals which, due to their construction, open a smaller gap when the gap is opened than the gap between the plastic profiles.

The embodiment according to FIGS. 50, 51 and 52 largely corresponds to the embodiment according to FIGS. 45 to 47, only with the difference that the shaped piece is integrated in a corner deflection 6369. Analog parts are provided with the same reference numerals as in the embodiment according to FIGS. 45 to 49, each increased by the number 100.

In the embodiment according to FIG. 50, the shaped piece 6358 is fastened to the deflection spring (not shown) and is guided in the deflection path 6370 which guides this spring. The first holding member 6355 is guided in the faceplate 6369a of the corner drive 6369. The shaped piece 6358 takes over the connection between the deflection spring (not shown) and a connecting rod piece 6367 connected to the gear lock 6371, which forms a structural unit with the faceplate piece 6366 and the gear lock 6371. The upper end of the faceplate piece 6366 overlaps the lower end of the leg 6369a of the corner drive and is fastened together with this to the sash frame material by a screw (not shown). The connection between the shaped piece 6358 and the drive rod piece 6367 is made by pins 6358a which engage in holes 6367a of the drive rod piece 6367.

Otherwise, the embodiment according to FIGS. 50 to 52 corresponds in structure and mode of operation to the embodiment according to FIGS. 45 to 49.

45 to 49 and 50 to 52 can also be modified such that the first holding member 6255 or 6355 is assigned to the upper casement leg 6018 and correspondingly the second holding member 6256 to the upper casement leg 6020.

The embodiment according to FIGS. 53 and 54 represents a further development of the embodiment according to FIGS. 45 to 49. Analogous parts are designated by the same reference numerals as in FIGS. 45 and 46, each increased by the number 200.

45-49, the second holding member 6456 is opposite the supporting part, i.e. supported displaceably relative to the locking plate 6468 in the direction of the double arrow 6456a, by means of a rivet 6456b which penetrates an elongated hole 6456c of the second holding member. The holding member 6456 in this case has two flanges 6456d and 6456e. The mode of operation is as follows: before the first holding member 6455 has reached the flange 6456d in the direction of the double arrow 6456a when switching to the split tilt opening, the first holding member 6455 must have engaged behind the flange 6456d perpendicular to the plane of the drawing in FIG. 53. If the cam follower 6428 then forces further opening of the casement relative to the window frame by sliding on the cam 6468a, the second mounting member 6456 is carried by the first mounting member 6455 in the direction of the arrow 6456a to the right as far as the stop between slot 6456c and rivet 6456b. When the casement is closed, the first holding member 6455 strikes the flange 6456e, so that the second holding member 6456 is pushed back into the position shown in FIG. 53. In this way, an increased gap opening width is possible even with a shallow fold depth.

35 to 44, it must also be added that the first holding member 6055 has to be inserted between the two flanges 6056a and 6056b before the interaction of the parts 6057 and 6034 has passed over the first holding member 6055, flange 6056b in the horizontal direction. The same applies to the embodiments according to FIGS. 45 to 52.

In the embodiment according to FIGS. 55 and 56, an opening device known per se is used on a tilt and turn window. This includes: a frame 1310, a wing frame 1312, a drive rod 1344 on the wing frame upper leg, a manual operating handle 1328 on the wing frame on the wing frame leg remote from the axis of rotation 1316, an extension arm 1336 mounted in a pivot bearing 1338, which is guided by means of a rotary slide connection on the wing frame 1312, and is also connected via an additional link 1337 to the sash frame 1312, an extension arm adjustment block 1352 on the drive rod 1344, an adjustment block receptacle 1354 on the extension arm 1336, a control curve 1356 in the adjustment block receptacle 1354, stop surfaces 1358, 1360 on the sash frame 1312 or frame 1310. Ein Frame frame is marked with 1340.

The extension arm 1336 is articulated at 1316 on the frame 1310 and connected to the casement 1312 by a rotary slide connection, not shown. The block 1352 serves in the locking position according to FIG. 55a and the rotating position according to FIG. 55b for locking the extension arm 1336 on the sash frame and thus enables the rotating operation in the rotating position.

55c, the adjusting block 1352 is moved into a section of the control cam lying further forward, so that the sash frame, as can be seen from FIG. 55c, has inevitably changed over and is secured in the gap tilting position. 55d, the adjusting block 1352 is opposite an opening of the control cam 1356, so that the sash frame can be tilted beyond the gap opening position into a position which is defined by the opening arm 1336. The raising arm 1336 works in the usual way with an additional link 1337, which is articulated on the one hand on the raising arm 1336 and on the other hand on the frame 1310. In addition to securing the gap opening by means of the curve 1356 and the block 1352, another can Securing the gap opening can either be provided between the opening device and the casement or between the drive rod 1344 and the frame.

The sections of the control cam 1356 which accommodate the adjusting block 1352 in the functional positions ROTATE and CLOSE on the one hand and in the functional position SPALT KIPP on the other hand are offset in parallel by means of a transitional slope and in the functional position CLOSE parallel to the frame level.

55a to 55d has the advantage that the gap opening securing elements 1352 and 1354 are attached to fitting parts which are supplied by the fitting factory, so that a false stop is not possible with regard to the gap opening securing elements 1352 and 1354.

56, the adjusting block receptacle 1354 of FIGS. 55a to 55d is modified. This Verstellkobenaufnahme 1354 is formed by an inner fork 1354a, which receives the Verstellkoben 1352 in the rotational position and the locking position. Furthermore, the adjustable block receptacle 1354 includes two outer movable fork legs 1354b. These movable fork legs 1354b are pivotally mounted in a longitudinally and transversely adjustable joint 1354c. One end position of the movable fork legs 1354b is determined by the inner fork 1354a, while the outer end position (upper half of FIG. 56) is defined by stop strips 1354d. Furthermore, the guide block receptacle 1054 includes a guide body 1354e which is mounted so as to be stiffly pivotable about an articulation point 1354 between two positions. By changing the guide body from the position shown in FIG. 56 to a symmetrical upper position, a change from right to left stop and vice versa can be carried out. In the gap-tilt position, the adjustment block 1352 is located between the guide body 1354e and the left end of the upper movable fork leg 1354b. In the tilt position, the adjustment block 1352 is located outside the left end of the upper movable fork leg 1354b. The mobility of the fork legs 1354b is important because the fork legs can be swiveled into the position in which the upper fork leg 1354b of FIG. 56 is located, so that the adjusting block 1352 is then also caught during the transition from the tilting position into the split tilting position can, if the sash is not fully pressed on the frame (enlarged suit). Nonetheless, when the window is completely closed, the movable fork legs 1354b can be pushed back within the outline of the extension arm 1336 by contact with the edge 1360 of the frame 1310 (FIGS. 55a to 55d), so that the fold dimension with regard to the width of the adjusting block receptacle 1354 is not must be increased and still an enlarged suit is achieved.

The embodiment according to FIG. 57 follows the embodiment according to FIGS. 10 and 12. Analog parts are provided with the same reference numerals as there, each increased by the number 100. The embodiment according to FIG. 57 differs from that according to FIGS. 10 and 12 essentially only in that the introduction funnel 2162 while maintaining the / Left usability essential symmetrical doubling is placed in the middle.

The embodiment according to FIG. 58 follows on from the embodiment according to FIGS. 19 and 20. Analog parts are provided with the same reference symbols as in FIG. 19, each increased by the number 300.

In contrast to the embodiment according to FIG. 19, the movable actuator 3346 in FIG. 58 is not firmly connected to the drive rod 3342a, but can only be taken along with the drive rod 3342a by a lost motion connection. The lost motion connection is generally designated 3370. The lost motion connection 3370 includes a driver 3372 connected to the drive rod part 3342a and a driver 3374 connected to the actuator 3346. The actuator 3374 is biased to the left in FIG. 58 in the sense of FIG. 58 by a biasing spring 3376 which is anchored to the faceplate 3350 Approach of a stop 3378 attached to the actuator 3346 to a stop 3380 attached to the faceplate 3350. In FIG. 58, the drive rod 3342a is in the position ready for tilting. In this position, the drive rod 3342a has taken the actuator 3346 to the right via the catches 3372 and 3374 while lifting the stop 3378 from the stop 3380. The drive rod fitting can be so stiff that it remains in the position of FIG. 58 against the action of the spring 3376. The sash frame can be pivoted back and forth between the closed position and the tilt opening position shown in FIG. 58, wherein the teeth 3366 on the additional link 3328 can pivot past the teeth 3346a of the actuator 3346. In the tilting ready position of the drive rod 3342a shown in FIG. 58, it is therefore also possible to bring the opening device 3332 and thus the casement into a position in which the teeth 3366 of the additional link 3328 face the teeth on the actuator 3346. This then means that a gap tilt position has been reached. This gap tilt position can be fixed by sliding the drive rod 3342a to the left in FIG. 58 by pivoting the rotary handle 3344 into the gap tilt fixing position so that the teeth 3346a engage with the teeth 3366. In this way, different gap tilt positions can be fixed. If the casement is to be closed from such a tilt-and-tilt position, the drive rod must be moved all the way to the right again by turning the handle 3344 to the ready-to-tilt position, ie to the position shown in FIG. 58. Then the sash can be pressed all the way down. If you now want to switch to ready to turn, the handle 3344 is brought into the ready to turn position; the driver 3372 moves with the drive rod 3342a to the left until the stop 3378 comes to bear against the stop 3380 which is fixed on the faceplate. Then the teeth 3346a and 3366 are engaged again, however, so that the extension arm 3324 and the additional link 3328 are parallel to the drive rod 3342a and thus to the casement. The position of the actuator 3346 then again corresponds to the gap tilt fixation. However, the drive rod 3342a can now be shifted further into the ready-to-turn position and finally also into the closed locking position, the driver 3372 rising from the driver 3372 from the driver 3374. The drive rod 3342a then locks the opening arm 3324 on the sash frame for the rotary operation and for the locking mechanism in the usual manner by means of the locking bolts 3338 and 3338 '.

A particular advantage of this embodiment is that when switching, the movable actuator 3346 no longer has to pass the additional link 3328. The additional link 3328 can therefore be made wider and, as shown, segment-like, so that larger gap opening angles are possible and right / left usability can also be considered.

58, the drivers 3372 and 3374 are only shown schematically, as are the stops 3378 and 3380.

59 shows, the lost motion connection 3370 can be formed by a foot 3374 of the movable actuator 3346, which engages in an elongated hole 3384 of the drive rod 3342a. In this case, the foot 3374 acts as one driver and the left end 3372 of the elongated hole 3384 as the other driver. The stop 3378 is formed by the left end of the actuator 3346 and the stop 3380 by the left end of an elongated hole leading the movable actuator 3346 in the faceplate 3350. In contrast to the schematic illustration of FIG. 58, the spring 3376 is designed here as a compression spring.

It is of course possible to also use this lost motion solution according to FIG. 58 in the embodiments according to FIGS. 15 to 23.
