Description

The present invention relates to a display device for a pivotally mounted tilt or turn-tilt sash, in particular window sash or door leaf, comprising at least one Ausstellarm, which on the wing about a first pivot axis and on Frame mounted pivotally about a second pivot axis or attachable, a drive device on the wing or on the frame with a by a drive displaceable drive unit, one at least a Ausstellarm associated transmission arrangement, by which a Displacement movement of the drive unit in a pivoting movement of the associated Ausstellarms is implemented, wherein the transmission arrangement a transmission member connected to the drive unit to a third pivot axis is pivotally mounted and that at displacement the drive unit pivoted about the third pivot axis, wherein the Transfer member acts on the stay and this to the first or second pivot axis pivoted.

From DE 33 45 870 A1 discloses a display device is known in which the transmission member in an end region by a wing-side Drive is displaceable and in its other end with a Ausstellarm cooperates. By a the extension arm in addition to Wing articulating auxiliary arm performs a displacement of the transfer member and thereby forcibly generated by the same pivoting that pivoted the stay arm with respect to the wing and thereby the wing for example, starting from a closed position in a tilted position is pressed. In this case, the transmission link and the pivot Extending arm in opposite directions, with the result that one between the stay and the transmission member formed angle with increasing approach approaches the tilt-open position at an angle of 90 °. The means, with increasing transition into the tilted position leads to one Displacement of the transmission member induced pivoting thereof to a progressively smaller associated pivoting of the Opening arm. This has the disadvantage that, especially in the initial phase an opening movement of a tilting window or the final phase a closing movement of the tilting window a linear displacement of the Transfer member to a relatively large associated pivoting movement the Ausstellarms and thus for example a window leads, with the consequence that, in particular in this movement phase, in which the Movement counteracting forces are greatest, only a very low power transmission can be achieved.

Furthermore, from the German patent application 1 708 852 a Ausstellvorrichtung for windows or doors known in which at Performing opening or closing operations, the transmission element and the Ausstellarm pivot in the same sense. In this movement However, both shift the pivot axis of the transmission element as well as the pivot axis of the extension arm with respect to the wing on which also induces the displacement of the transmission element Drive device is provided, in the same direction, also with the consequence that forcibly upon displacement of the transmission element induced pivoting of the same in the initial phase of a Öffenbewegung or the final phase of a closing movement to a relatively large Kipphub leads with correspondingly low tipping force.

Furthermore, these known Ausstellvorrichtungen have the disadvantage that to obtain a desired employment of the extension arm, d. H. one desired tippingubs of a wing with respect to a frame, a relative extensive linear displacement of the drive unit is required, especially if even the required opening and Closing forces are to be provided, with the result that, for example difficult is the displacement drive for the transmission arrangement with a displacement drive for others, for example, provided on the wing Locking elements to couple, which in general only one require relatively small stroke.

A generic forming stand is known from DE 11 11 061 B. In this known Ausstellvorrichtung is a stay in his two End areas with a wing or a fixed frame pivotally connected. A transmission member is in a first end region the same on the extension arm in a longitudinal center region pivotally appropriate. In a second end region, the transmission element is provided with a Drive rod coupled. A shift of this drive rod shifts the coupling region thereof with the transmission member, so that forcibly an opposite pivoting of this transfer element and the Ausstellarms is generated.

EP 0 740 041 A1 discloses an opening device in which a Transfer member and a stay arm when performing a Tilting movement are also in opposite directions pivot. The Transfer member has essentially two components, which in Implementation of the pivoting movement relative to each other are displaced.

GB 1 112 535 C discloses a display device in which a Extending arm in its swiveling and sliding on a wing tailed end region has a groove-like recess into which a wing-proof pin engages. By shifting the to the wing pivotally connected end portion of the extension arm by means of a Espagnolette module can by interaction of the pin with the in Ausstellarm provided groove pivoting of the stay and thus the tilting movement of the wing are forced.

It is the object of the present invention, a Ausstellvorrichtung for a pivotally mounted on a frame tilt or turn-tilt wing to provide, by which improved tilting forces at small adjustment stroke of a drive unit can be achieved.

According to the invention, this object is achieved by an opening device for a pivoting or tilt-and-turn wing pivotally mounted on a frame, in particular window sash or door leaf, comprising at least a stay arm, which on the wing about a first pivot axis and on Frame mounted pivotally about a second pivot axis or attachable, a drive device on the wing or on the frame with a by a drive displaceable drive unit, one at least a Ausstellarm associated transmission arrangement, by which a Displacement movement of the drive unit in a pivoting movement of the associated Ausstellarms is implemented, wherein the transmission arrangement a transmission member connected to the drive unit to a third pivot axis is pivotally mounted and that at displacement the drive unit pivoted about the third pivot axis, wherein the Transfer member acts on the stay and this to the first or second pivot axis pivoted.

In the display device according to the invention is further provided that at Pivoting the at least one extension arm from a closed position the wing associated first pivot position in the direction of a a tilt-open position of the wing associated second pivot position to obtain a large swivel angle with low displacement of the Drive unit, the transmission member and the associated extension arm by the sliding movement of the drive unit swivel in the same direction and that for generating the the pivoting movements addressed the transmission order comprise: one between the transmission member and one with respect to the a pivot axis fixed guide component acting first Guideway arrangement with a first guideway in the guide component or the transmission element and a displacement of the Drive unit along the guideway feasible guide part on the each other component of guide component and transmission element, wherein the guideway of the first guideway assembly at least partially with respect to the direction of displacement of the drive unit slants.

The measures of the present invention ensure that defined in Way by moving the transfer member to the Pivoting range of the Ausstellarms - which goes along with that by the transmission member provided Verschwenkwirkung in a closer to Pivot point of the extension arm lying area is effective - initially at relatively far away from the pivot point of the extension arm lying Pivot point of the transmission link, a shift and pivoting the same only a relatively small Verschwenkweg the Ausstellarms induced. That is, especially in the initial phase of the Öffenbewegung a wing leads to a predetermined Verstellhub the drive unit a relatively small Ausschwenkwinkel a wing, which is a corresponding Power translation has the consequence. Approaching, however, in the course the pivoting movement of the pivot axis of the transfer member to the corresponding pivot axis of the extension arm, so is the transmission member forcibly in an area closer to the extension arm effective, so that due to the shortened leverage a predetermined Displacement stroke of the drive unit to a much larger Swivel angle of the extension arm and thus a significantly reinforced Tilting movement of the wing leads. The same applies vice versa Transition from an open or tilted position of a wing into one Closed position, initially due to the close to the pivot axis the Ausstellarms lying pivot axis of the transmission element at Shifting this transfer element initially a relatively large Angular motion of the wing is induced, and when approaching the Closed position of the same Verschiebehub a significantly reduced Tilting causes, with the result that a wing, for example effectively tilted against an opposing force generated by a wing seal can be.

Furthermore, the erfindunsgemäße Ausstellvorrichtung at low Width to the result that by closer to the pivot point of the stay become effective transmission element a much larger Verschwenkhub this extension arm can be achieved, with the result that for example, the displacement movement of the pivot axis of the transmission element to a displacement movement of a conventional Espagnolette system can be coupled in a window sash.

The term "attached to the wing or frame Ausstellvorrichtung "should make it clear that the respective pivot axes or the components defining these pivot axes after attachment of the system according to the invention Frame or wing are not displaced. That is, the Pivot axes can each be defined or formed by components, which are set on the frame or on the wing.

Preferably, the drive unit can at least one by the drive include in its longitudinal direction displaceable drive rod.

In particular when using the display device according to the invention in difficult to access areas, such as B. when used as skylights, it is advantageous if the drive is an electric motor drive with a Umsetzgetriebeanordnung comprises, by which a rotational movement of a Motor component in a linear displacement movement of the drive unit is feasible.

In the display device according to the invention may also be provided that when mounted on the wing or on the frame display device the first and the second pivot axis with respect to the wing or frame, and that in the case of Pivoting the at least one extension arm from a closed position the wing associated first pivot position in the direction of a a tilt-open position of the wing associated second pivot position the third pivot axis by displacement of the drive unit in the direction moved to a pivot axis of the first and second pivot axis is about which pivot axis of the stay on that Assembly of wing and frame pivotally mounted or attachable is, on which the drive device is provided or provided.

Alternatively or as an auxiliary drive, it is possible that the drive comprises a manually operable drive, preferably with a rotatable handle and a rotary movement of the handle into one Linear displacement movement of the drive unit implementing Umsetzgetriebeanordnung.

Furthermore, it is to implement the sliding movement of the drive unit advantageous in a pivoting movement of the extension arm when the Transmission arrangement further comprises: one between the transmission member and the Ausstellarm acting second guideway assembly with a guideway in the transfer member or in the stay and a guided during displacement of the drive unit along the guideway Guide part on the other component of transmission element and Ausstellarm, wherein preferably the guideway of the second guideway assembly at least regionally with respect to a longitudinal direction of the Ausstellarms obliquely.

By each inclined guideways is achieved that at Forcibly caused displacement movement of a guide member along the guideway at the same time a pivoting movement of at least one of the components which the guideway or carry the guide part, is induced.

To obtain the mentioned motion translation at least in the End phase of a tilting movement, it is advantageous if, for example, the Guideway of the first guideway assembly and the guideway the second guideway assembly in their respective obliquely running Area run so that when moving the drive unit for Swiveling the extension arm from the first pivot position in the direction the second pivot position of the extension arm to the first pivot axis with pivots a larger swing angle than the swing angle to which the transfer member in this movement to the third Swivel axis pivots.

This can be achieved, for example, that the guideway of first guideway assembly and the guideway of the second Guideway arrangement starting from an area in which the respective guideways associated with guide parts in the first Swivel position befindlichem stay out, lie in the direction of the Drive unit at least partially converge or run away from each other.

As already mentioned, according to a preferred type of use the Lifting device according to the invention in conjunction with a conventional Espagnolette system on a casement or door leaf be used. By such espagnolette systems are so-called Locking slide displaced, which after passing a predetermined Schiebeweges emerge from corresponding closing traps and thus the Release the sash for pivoting or tilting movement. So there starting from a closed position, the locking pins must first be moved, without necessarily inducing a tilting movement of the wing, and only after the release of the locking bolt from the associated closing traps and further movement of the drive rod system, the tilting movement is induced according to another aspect of the invention proposed that the guideway of the first guideway assembly and / or the guideway of the second guideway assembly starting from an area in which that of the respective guideway associated Guide part in located in the first pivot position Ausstellarm lies, along the direction of displacement of the drive unit or the longitudinal direction of the extension arm extending first section and subsequently to this first section a with respect to Displacement direction or the longitudinal direction obliquely second section.

Since according to the invention the at least one extension arm both on the frame as well as on the wing to fixed, so not with respect to these modules displaceable or substantially non-displaceable axes pivotable is to be, it is advantageous if to enable the length compensation in the Range of the extension arm when performing a tilting movement of at least one extension arm, a first arm portion and a second Arm portion which with respect to each other substantially in one Armlängsrichtung are telescopically displaced.

For this purpose, for example, be provided that at one of the arm portions at least one guideway is provided along which an am another arm portion provided guide part is displaced.

Furthermore, it can be provided that at least two guideways are provided and that one of the guideways with respect to another Guideway runs obliquely. Such a configuration has the advantage with the result that in by the transmission arrangement in a predetermined Condition with respect to the frame or the wing held Ausstellarm and by the inclination of one of the guideways of the telescopic Connection of the two arm sections an additional contribution to Verkipphub of the wing can be delivered, depending on the inclination direction this guideway this additional Hubbeitrag the is added to or removed from normal existing Kipphub is.

When used with a turn-tilt wing would have the telescopic connection between the two arm portions of the at least one extension arm As a result, that in transition from the closed position to a rotational opening position in the upper region of the wing, in which such a display device is generally provided by the substantially free telescopic connection of the two arm sections a lacking Holder of the wing with respect to the frame would be provided. It will therefore proposed to provide a lock-up arrangement by which in the first pivotal position of the extension arm, the telescopic Bridge bridged connection between the first and the second arm portion is.

Especially with larger and heavier wings, it is advantageous if at least two Ausstellarme with these respective associated transmission arrangements are provided. These can then be across the width a wing be positioned distributed.

It can be provided, for example, that the at least two Pivot arms when pivoting from the first pivot position in the direction be pivoted in opposite directions to the second pivot position.

To this opposing pivoting of the two Ausstellarme too which ultimately gives an even better distribution of forces over the width of a wing can be achieved, it is suggested that each the at least two Ausstellarme a drive unit of the drive device is assigned and that the at least two Ausstellarmen associated drive units by the drive to each other in opposite directions are displaceable.

This opposing sliding movement of the two drive units can For example, by acting between the two drive units Change gear arrangement can be achieved. In this case it is advantageous if for actuating the Ausstellvorrichtung invention, d. H. to the Tilting a grand piano, the impulse on a motor transposition in the Intermittent gear acting component acts. It is thus one central force introduction provided through which to both sides in a uniform manner, a proportion of the actuating force on the respective transmission arrangements is distributed, with the result that a Smooth and even tilting movement of a wing generated becomes. In this case, so the change gear is a device through which both drive units in different directions to the sliding movement are driven. The effecting the implementation Component is then the drive component.

Should also be in a Ausstellvorrichtung with several Ausstellarmen Rotary operation of the associated wing be possible, so it is advantageous if at least one of the extension arms in the region of the second pivot axis detachably coupled to the frame or can be coupled. It will be up this way, for example, in the two corner areas of a Wing provided couplings of the extension arms to the frame solved on one side, so that the wing then about the second pivot axis of the in the other corner lying or coupled to the frame Ausstellarmes can pivot.

Here it is advantageous if a decoupling device is provided, by which the rotational coupling of at least one of the Ausstellarme with the frame in the region of the second pivot axis is solvable.

If a wing used both in rotary operation and in tilting operation be so, it must be ensured that in the tilting mode in the lower edge area the wing at least two bearing points are provided to which of the Can tilt wings, and that in the swing operation of the wing, at least two pivot points lying on a lateral edge of the wing are provided, which can take place about a pivoting movement. If several Ausstellarme are provided and to enable the Pivoting movement the pivotal coupling of one of the pivot arms must be solved to the frame, then it is advantageous if through the Decoupling device further in decoupling of the stay of the Frame in the region of the second pivot axis a tilting bearing assembly is releasable, through which the wing on the frame to carry out a Tilting is pivotally attachable or attached.

Furthermore, it can be provided in the display device according to the invention be that the at least two Ausstellarme at pivoting of the first pivotal position in the direction of the second pivotal position in the same direction be pivoted.

When using several extension arms on a wing it can be required, the frame-side couplings of the same in different Make levels. That is, a condition can occur in which the second pivot axis of one of the extension arms with respect to second pivot axis of another of the extension arms substantially in a direction is offset in which at the transition of a respective Ausstellarmes from the first pivot position to the second pivot position the first and the second pivot axis to move away from each other. Would in such a case two similar acting Ausstellarme used be, the offset of the two second pivot axes of the Ausstellarme to a restriction in the area of the wing at the transition from the closed position in the tilt-open position lead. To this, too It is also proposed that when moving from the first Swivel position for the second pivoting position through the one extension arm provided tilting stroke with respect to one by the other extension arm Kipphubs prepare for an offset between the respective ones Swivel arms associated second pivot axes corresponding Amount is increased or decreased. It should be noted that ever according to which direction the offset is present, d. H. with regard to the Tilting movement to the front or to the rear, in a corresponding manner at one of the pivot arms a reduced or increased swing stroke must be provided.

To one equipped with a display device according to the invention Wing for adaptation, for example, to different ventilation situations To be able to position differently, it is proposed that by the Drive the at least one extension arm in at least one intermediate position between the first pivotal position and the second pivotal position is durable.

In a particularly simple to construct and expedient embodiment the drive means is provided for attachment to the wing. In this case, the already mentioned advantage can be achieved that Each drive unit of the drive device with a drive rod assembly coupled to the wing which is coupled or a part of the drive rod assembly forms.

According to the invention it is further proposed that when performing a telescopic movement the two arm portions with respect to each other the first and the second Arm portion are forcibly inclined with respect to each other.

Forcibly induced by the occurrence of the telescopic movement Tilting of the two arm sections and beyond provided defined positioning of one of the arm portions opposite the Frame or the wing, as already stated above, a additional contribution to the tilt angle of the extension arm are supplied so that by a predetermined displacement stroke of the drive unit larger pivot angle of a wing can be achieved.

It is understood that such a configuration with the previously described advantageous embodiments, in particular the movement of the pivoting range of the transmission member on the Swivel range of the extension arm to, can be combined so that here another synergetic effect of these two individually advantageous effects can be achieved.

The present invention further relates to a tilt-window or tilt-and-turn window, in particular skylight, with a display device according to the invention or / and a turn-tilt door with an inventive A stay mechanism.

The turn-tilt window 10 has a fixed frame 12th on, as well as with respect to the frame 12 both rotating as well tiltable wing or sash 14. On an upper horizontal spar 16 of the wing 14 is the Ausstellvorrichtung described in detail below 18 attached, which at the other end in a pivot bearing 20 am Frame 12 is hinged. In the lower right corner of the wing 14 is over a corner bearing 22 with respect to the frame 12 both to a horizontal Axis A1 tiltable and pivotable about a vertical axis A2 stored. At the lower left corner of the wing 14 via a detachable tilting bearing 24 pivotally mounted on the frame 12 about the horizontal axis A1.

In a conventional manner is indicated on the wing 14 a dashed line Espagnolette system 26 is provided, which has a plurality of Locking pad 28 can move, depending on the movement position with not shown, provided on an inner surface 30 of the frame 12 Striking plates or closing traps can interact to to lock the wing 14 with respect to the frame 12. The Espagnolette system 26 has in known per se respective corner deflections 32 and is for example drivable by a handle 34, which upon pivoting in the direction indicated in Fig. 1 arrows over a Gear rack and pinion mechanism the drive rod system 26 for Can drive movement. Alternatively, as below described, an electric motor drive 36 may be provided, which for example, also via a gear rack drive a Rotary movement in a linear displacement movement of the espagnolette system 26 to thereby move the locking pins 28 and how to be described below, the display device 18 for tilting to control the wing or sash 14.

FIG. 2 shows a plan view of such a display device 18. This includes a generally designated 38 Ausstellarm, in a End region on a cuff rail 40 about a pivot axis S1 pivotally is attached, wherein the pivot axis S1 in the closed state of Window represents a substantially vertical axis. These Faceplate 40 is in a conventional manner on an outer peripheral surface 42 (Fig. 1) of the wing 14 and conceals this in one Flügelfalznut lying espagnolette 26, of which in Fig. 2 a under the face plate 40 lying drive rod portion 44 by dashed lines is indicated. The display device 18 is then located substantially in the Folding air between the surfaces 42 and 30 of the wing 14 and of the frame 12.

In its other end of the stay arm 38 is provided with a bearing sleeve 46 of the recognizable in Fig. 20 pivot bearing 20 connected.

On the face plate 40 is also a recognizable in Fig. 8 guide plate Set 48, wherein fixing the guide plate 48 of the Ausstellarm 38 rotary bearing bolt or rivet 50 is used, and at the other end a separate fastening bolt or rivet 52. It should be noted that for ease of pivoting between the guide plate 48 and the extension arm 38 a sliding bearing part, for example a Teflon part 54, can be positioned.

The guide plate 48 has two slot-like openings, from which is closer to a designated 56 of the pivot axis S1 and closer essentially in a straight line in the longitudinal direction of the faceplate 40, d. H. in Circumferentially extends, and the other, designated 58 of the Swivel axis S1 is further away. The slot-like opening 58 has a first substantially rectilinearly extending in the circumferential direction Section 60, a curved transition region 62 and a second with respect to the circumferential direction inclined portion 64 on.

The slot-like opening 56 passes through a fastening bolt or rivet 66, which is fixed on the one hand on the drive rod portion 44, and the on the other hand on the guide plate 48, a transfer plate 68 to a fixed with respect to the drive rod portion 44, but with this in the circumferential direction linearly displaceable axis S3 carries pivotally. In their from the pivotal attachment to the drive rod portion 44th remote end portion, the transfer plate 68 in the form of a Bolts or rivets formed guide projection 70, which is with respect to the transfer plate 68 extends down and into the slot-like opening 58 engages. That is, the slot-like opening 58 forms with its two side surfaces 72, 74 a guideway for the Guide projection 70 on the transfer plate 68th

Laterally offset with respect to the guide projection 70 is on the transfer plate 68, a further guide projection 76 is provided, which However, in the opposite direction, d. H. extends upwards and into a slot-like opening 78 in a widened area 80 of the Ausstellarms 38 engages. Also the slot-like opening 78 in the stay 38 has two sections, one from the pivot axis S1 farther away and to the longitudinal direction L of the extension arm 38 substantially parallel first section 82nd and a subsequent to a transition region 83, the pivot axis S1 closer and inclined with respect to the longitudinal direction L. second section 84.

It can be seen in Figs. 2 and 3 further, that the extension arm 38 of two Arm sections 86, 88 is constructed. The arm portion 86 is at the Faceplate 40 pivotally mounted, and the arm portion 88 carries the Bearing sleeve 46 and is pivotable on the aperture frame 12 about the axis S2 attached or attachable. One of the arm sections, namely the arm portion 88, has two slot-like openings 90, 92, in which fixed to the arm portion 86 guide pin 94, 96 in essentially in the longitudinal direction L of the extension arm 38 can be guided. It is in this way in the transitional area between the two Arm portions 86, 88 a telescopic connection 98 created, which when performing a tilting movement a length compensation of both the frame 12 and the wing 14 with respect to these each substantially stationary axes S2 and S1 allow articulated Ausstellarms 38. It should be noted that the Assembling the two arm portions 86, 88, the slot-like Apertures 90, 92 each have enlarged end portions 100, 102, through which heads of the guide pins 94, 96 are passed can. A position in which the heads of the bolts 94, 96 with these extended sections 100, 102 are aligned, however, occurs in the normal operation of a window does not occur in order to avoid the two Arm sections 86, 88 unintentionally detached from each other.

To operate the Ausstellvorrichtung 18 serves, as already above addressed, a gear rack assembly, which in Fig. 3rd is recognizable. This comprises several on the drive rod section 44 Recesses 108, which together with the recesses 108th separating webs 110 form a rack-like formation. Further is in a carrier 112, an externally toothed wheel 114 is rotatable mounted, which has a Innenvierkantöffnung 116. In these Innenvierkantöffnung 116, for example, a square bar a to be described below handle to the Wheel 114 for rotation and thus the drive rod portion 44 for To propel displacement, or it can, for example, on the square bar a worm or gear to be arranged, which with a Worm or gear of a rotary shaft of the electric motor drive 36 of FIG. 1 meshes, so that the drive can be done by an electric motor. In particular, in electromotive drive, it may also be provided assign this drive a transfer gear, which is a rotary motion of the rotor converts into a linear displacement movement, for example also via a worm gear, in which case, for example, on Espagnolette section 44 two mutually spaced projections can form a receiving opening into which a driver of the linear slidable component of the transmission engages the drive rod section 44 to move.

The following is the function of the display device according to the invention in particular with reference to Figs. 7, 9 and 10 described. It was initially assumed from Fig. 10, which is a position of the stay 38 or the section 86 recognizable there the same, which corresponds to a closed position Z of the wing 14. That is, in this position, the stay arm 38 is substantially congruent over the faceplate 40. This is a position in which the drive rod portion 44 shifted to the maximum extent to the right is, so that the two guide projections 70 and 76 respectively in End region of the extending in Stulpschienenlängsrichtung section 60 and 82 of the respective slot-like openings or Guideways 58, 78 are located. In this position, the display device 18 even a lock before, as well as by exercising a Tilting force on the wing 14, for example by wind, the Guide projections 70, 76 are not displaced in sections 60, 82 can be. It can also be seen that the sections 60, 82 of the slot-like openings 58, 78 are laterally spaced and respectively near a lateral end portion of the guide plate 48, respectively the widened portion 80 of the stay arm 38 are positioned. To their respective curvature regions 62, 83, the openings extend 58, 78 then obliquely to Stulpschienenlängsrichtung each other lateral end portion of the guide plate 48 and the widened Section 80 of the stay arm 38. In this way is, as will be seen below, with minimal lateral Width achieved the greatest possible Verschwenkeffizienz. It is, however pointed out that the two slot-like openings 58, 68 other can have lateral positions to each other. This is above all therefore possible because they are not provided in the transfer plate 68, but in different components.

Now, starting from the positioning shown in Fig. 10 by the drive, d. H. either a handle 34 or an electromotive Drive 36, the drive rod portion 44 shifted to the left, so moves until reaching the curved portions 82, 83 of the Ausstellarm 38 initially not with respect to the face plate 40th In this Displacement, however, the locking pins 28 of the espagnolette system, which is coupled to the drive rod portion 44, from their respective striking plates or closing traps are led out. So long However, the locking block still in closing interaction with the assigned closing traps, may and may be a pivoting or Tilting the wing 14 does not occur. After reaching the curvature sections 62, 83, however, the locking pins 18 are no longer in closing engagement with the associated closing traps, and after passing this in Fig. 9 recognizable positioning of the guide projections 70, 76, the Start pivoting movement of the extension arm 38.

The guide projection 70 now moves in the oblique Section 64 of the opening 58 in, as can be seen in Fig. 7, so leads the ongoing displacement of the drive rod portion 44th and the associated displacement of the pivot axis S3 of Transfer plate 68 in the direction of the pivot axis S1 of the stay 38 to a pivoting movement of the transfer plate 68th with respect to the faceplate 40 and thus the wing 14. This pivoting movement the transfer plate 68 about the axis S3 is through the Guide projection 76 also transmitted to the extension arm 38. However, since the guide projection 76 in the obliquely extending portion 84th the opening 78 runs, is additionally a pivoting movement of the Ausstellarms 38 with respect to the transfer plate 68, but in the same Panning direction forced. Ultimately, then forms the transfer plate 68 with its two guide projections 70, 76 a wedge at Approach of the pivot axis S3 to the pivot axis S1 between the two surfaces or wedge surfaces formed by the openings 58 and 78 74, 118 is pushed in and thereby the extension arm 38 of the Cuff rail 40 pivots away. Since the two guide projections 70, However, they do not necessarily have to extend in different directions the two wedge surfaces 74, 118 converge in a wedge shape, they could also run away from each other, as indicated in Fig. 7a is. Also there leads a movement of the two guide projections 70, 76th in the arrow direction, that the guide projection 70 along the through the Opening 58 formed guideway is moved up and that by the thus also upwardly shifting guide projection 76 also the guideway 78 is moved up, which is reinforced by the fact that the guide projection 76 along the inclined portion of the guide track 78 moves.

This principle of operation achieves several advantages. On the one hand one recognizes that by the two inclined track sections one induced by linear displacement of the drive rod portion 44 Displacement movement of the pivot axis S3 and thus the transfer plate 68 in an even larger pivoting movement of the extension arm 38th implemented around the pivot axis S1 and thus also the pivot axis S3 becomes. This is particularly important when the inventive Ausstellvorrichtung 18 in conjunction with a normal Espagnolette system should be used. In such espagnolette systems is the displacement stroke of the respective drive rod sections in given a first part of the Verschiebehubs, such as previously mentioned, for releasing the closing engagement of the locking bolt is required with the associated closing traps, and only the second part of the Verschiebehubs can be used to a pivoting movement of the Ausstellarms cause. That is, this relative small shift stroke must be in the largest possible swing and thus Kipphub the wing 14 are implemented. Another advantage of Ausstellvorrichtung invention is that by the wedge-like acting Transfer plate 68, which with increasing pivoting of the Ausstellarms 38 of the pivot axis S1 thereof approaches, starting from the closed position initially the points of attack on the extension arm 38th on the one hand and on the faceplate-fixed guide plate 48 on the other are relatively far away from the pivot axis S1. That is, one Displacement stroke of the pivot axis S3 leads with a predetermined amount to a relatively small pivoting of the extension arm about the pivot axis S1. However, approaches the pivot axis S3 of the pivot axis S1 in the course of the sliding movement of the drive rod portion 44, so also occur the interaction points, defined by the guide projections 70, 72 closer to the pivot axis S1 zoom. A shift stroke by the same amount therefore necessarily leads to a much larger one Pivoting movement of the Ausstellarms 38, which by the respective sloping surfaces of the openings 58, 78, which the guideways form, is still supported. However, this means that in the field of Closed position at the beginning of a Öffenbewegung or at the ends a closing movement relatively large forces can be provided for example, on the frame 12 or on the wing 14 existing To deform seals.

It should be noted that the above with reference to Figs. 2 to 10 system described in particular for use in tilting wings is suitable, such. B. provided in larger halls skylights. Here a rotational position is not required, and the tilting bearing 24 (Fig. 1) be a permanently coupled bearing, and in the embodiment of the respective slot-like openings 58, 78, the rectilinear portion 60 or 82 are made relatively short, with the advantage that at the same total extension length, the inclination of the oblique Section 64 and 84 with respect to the direction of the Espagnolette section 44 (at the section 64) respectively with respect to the longitudinal direction L of the extension arm 38 (in the section 84) can be kept small. This in turn causes that to move the wing favorable force conditions exist.

In Fig. 2 is indicated by a dashed line S that one of the guide openings 90 or 92 with respect to the longitudinal direction L of the Ausstellarms 38th could be inclined. The tilting of this guideway 98 would result that in forcibly occurring during the tilting process Telescopic movement of the two arm portions 86, 88 with respect to each other these are forced into an oblique position relative to each other, which is schematically illustrated in Fig. 2a. Since the arm portion 86 through the transfer plate 68 in each shift position of the drive rod portion 44 in a predetermined angular position with respect to the face plate 40th and thus the wing 14 is held, the additional tilting leads the two arm portions 86, 88 to that forced against an in Fig. 2a indicated by dashed lines rectilinear configuration of Ausstellarms 38 an additional tilting W can be obtained. Alone This measure can therefore be independent of the previously described Functioning in the area of the transfer plate to be used a predetermined displacement stroke of a drive rod section in a enlarged Schwenkhub the Ausstellarms or tiltable Implement wing.

It should be noted that the extension arm 38 also more than the may have two illustrated arm portions, so for example three Arm portions may have, of which in each case two in the previously described manner telescopically connected together could be. Even with such a design with several Arm sections can then at least in the range of one of the telescopic Connections provided the inclination of a guideway to to obtain the above-mentioned effect.

FIG. 11 shows a handle device 34 which is used to control the previously described system can be used. It's the Square bar 122 can be seen, which with the previously described toothed wheel 114 connectable for common rotation is. The square bar 122 is supported by a bearing assembly 124 at one Wing 14 attachable support unit 126 rotatably mounted. He goes through Furthermore, a square opening 128 in the handle portion 130 and carries on his End serving as a push button cap 132. On this cap 132 supports a spring 134, which at the other end presses on the handle part 130 and biasing it toward the support unit 126, as shown by the Bearing assembly 124 of the square bar 122 with respect to the carrier unit 126 rotatably, but not held in its longitudinal direction is not displaceable. To the rotatable mounting of the square bar 122 has the Carrier unit 126 several z. B. conical depressions 136, the preferably with uniform mutual distance in the circumferential direction are arranged around the square bar 122 around. On the handle part 130 is preferably a corresponding number of z. B. conical Projections 138 are provided which have the same relative spacing as the recesses 136 have. By the spring 134, the projections 138 biased toward the recesses 136 so that with appropriate relative rotational positioning between the handle portion 130 and the support unit 126, the protrusions 138 in the recesses 136th engage and thus provide a rotational security for the handle portion 130.

If the handle portion 130 to be moved, so can by grabbing the same with the fingers of one hand and supporting the thumb at the Cap 132, the handle portion 130 of the support unit 126 against the Bias of the spring 134 are pulled away so that the projections 138 exit from the recesses 136. The handle portion 130 may then for actuating the opening device 18 described above be pivoted and after reaching a desired tilting position of a Wing are released again, so that the projections 138 back in engage the recess 136 and by the thus formed locking keep a wing in a predetermined tilted position. Due to the cone-shaped Embodiment of the recess 136 and the projections 138th The operation can also be done solely by rotation, wherein then first by sliding the respective conical surfaces together Spring 134 is compressed and then upon rotation of the handle portion 130 after reaching the next relative orientation of the protrusions 138 with the Recesses 136 again a catch occurs. It should be noted that a reverse situation is possible, d. H. the projections could be provided on the carrier unit 126. It is not required to provide as many projections 138 as recesses 136 are provided. It only needs to be taken to ensure that the Number of recesses at least equal to the number of protrusions is. To obtain a stable rotation as possible, the Numbers, however, be the same size. It should be noted that in particular maintaining an electromotive drive Any intermediate position can also be achieved by that the implementation of a rotational movement of an engine component in one Displacement movement of the drive rod portion 44 by a self-locking Transfer gear takes place.

FIGS. 12 to 19 show a modification of the invention Ausstellvorrichtung, which in particular for use in turn-tilt wings suitable is. The basic structure corresponds to the previous one detailed structure, so that a further explanation is not here is given. However, it is with reference to Figs. 15 to 17 on it noted that when used with a turn-tilt wing, the respective rectilinear opening portions 60, 82 of the slot-like Openings 58, 78 be extended with respect to the use in tilting wings must, with the consequence, that accordingly the oblique sections 64, 84, which between the rotational position D and the tilting position K lie, are shorter and thus to obtain the same Kipphubs a larger Inclination with respect to the respective rectilinear portion have to. This configuration is due to the fact that in the transition from the position Z, which corresponds to the closed position, to the rotational position D, A larger stroke is required to lock the locking pins in one position bring, which allows the rotation of the wing about the vertical axis A2. Otherwise, in this embodiment, the two openings 58, 78 the rectilinear section required to first the Release the locking bolt without already induced tilting movement allow, and after passing through the rotational position by the previously described effect exhibiting the Ausstellarms 38th obtained by means of the sloping sections. It is in this Connection still noted that to obtain the pivoting movement it is particularly advantageous that, for example, in the slot-like opening 58 a lateral offset between the pivot axis S2 and that surface area of the guideway is created, where the guide projection 70 is supported. The same applies for the guide projection 76.

For use with a turn-tilt wing, it is necessary to ensure that in rotary operation, the telescopic connection 98 between the two Arm portions 86, 88 is not effective. It would then be through this telescopic connection a lack of fixation of the wing in the upper Area with respect to the frame 12 available. For this purpose is a bridging arrangement 140 is provided, which on the face-plate 40 includes a lock-up bolt 142, and at the arm portion 88, which pivots on the frame 12 about the axis S2 attached, includes a bridging shoe 144. Is the arm 38 positioned in the closed position shown for example in FIG. 17, in which the arm portion 88 is located above the face plate 40, so is the Bridging bolt 142 received in the shoe 144 and through the both in the longitudinal direction of the arm portion 88 separated sections 146, 148 of the bridging shoe 144 is a relative movement the faceplate 40 with respect to the arm portion 88 in Stulpschienenlängsrichtung and thus not in the longitudinal direction L of the stay arm 38 possible. It can then the wing 14 with bridging the telescopic Connection 98 to be moved in the direction of rotation. But that's it still necessary, the bottom left in Fig. 1 recognizable tilting bearing 24 to to solve. This can for example be done by manually on am Kipplager 24 existing release lever is actuated to a bearing pin to move out of a bearing eye. Please enter again below Tilting must be done by re-folding the lever of the bolt be moved back into the bearing eye, again in this area a defined mounting of the wing 14 with respect to the frame 12th provided. When passing into the tilting position then enters the lock-up bolt 142 from the bridging shoe 144, so that the arm portion 88 and the face plate 40 with respect to each other unhindered can be moved.

Furthermore, it can be seen in Figs. 12, 13 and 14, that an additional Locking arrangement 150 in the region of the rotary bearing 20 (FIG. 1) can be provided. This locking arrangement 150 comprises For example, an extension portion 152 for the drive rod section 44, which with a toothed shoe 154 in a conventional manner in sliding coupling with a toothed portion 156 on the drive rod section 44 can be brought. Furthermore, the locking arrangement comprises 150 a Stulpschienenabschnitt 158, which on Wing can be set. This cuff rail section 158 slidably passes through a bearing pin 160, which another Closing 162 carries. At the arm portion 88 is for the closing cam 162nd a latch 164 is provided which upon displacement of the drive rod portion 152 in the longitudinal direction in an opening portion 166 the Can receive locking bolt 162 and this then in the lateral direction prevents movement relative to the arm portion 88. The for recording the closing bolt 164 serving closing latch 164 is via a rivet 168 pivotally mounted on the arm portion 88 and has an eccentric arrangement 170 to 164 by appropriate positioning of the latch with respect to the arm portion 88, the wing upon the occurrence of the locking pin 162 in the opening 166 forcibly bias against the frame 12.

Fig. 19 shows a different configuration of the slot-like Openings or guideways 58, 78. It can be seen that in the Transition regions 62, 83 a significantly larger radius of curvature so formed guideways is provided so that the transition from the rectilinear to the inclined sections is gentler and thus easier operation is possible. The radius of curvature These transitional areas 62, 83 should in any case be in one area greater than the radius of curvature of the guide projections 70, 76, and is preferably in a range of 10 to 20 mm. you recognizes that in the embodiment of FIG. 19 to the with respect to the respective directions inclined portions 64, 84th again in the direction of the faceplate 40, d. H. in the direction of displacement the drive rod portion 44 extending portion 172 and a extending in the longitudinal direction of the extension arm 38 Section 174 connects. These sections result in that Approaching the opening position, a predetermined displacement stroke of the Espagnolette section 44 and thus the pivot axis S3 of the transfer plate 68 again leads to a lower Verschwenkhub, so that there is also a favorable force transmission ratio in the final phase, especially when closing a wing easier operation allows. When entering into section 172 is through the then straight and parallel to the slot-like opening 56 guided guide projection 70, the transfer plate 68 is no longer pivoted. However, since the guide projection 76, which in the slot-like opening 78 on Ausstellarm 38 engages, not rectilinear to the pivot axis S1 is moved, but parallel to the sliding movement of the pivot axis S3 is guided past the pivot axis S1, nevertheless becomes a Pivoting the Ausstellarms 38 generated. It can therefore be seen that to cause a pivoting movement of the extension arm 38 in principle the guideway 78 does not have a sloping section would, since with respect to a by the pivot axes S3 and S1 passing line laterally offset guide projection 76 forcibly leads to a pivoting of the extension arm 38.

It should be noted that even when used in conjunction with Tilt-and-turn wings drive the drive rod section 44 respectively the entire espagnolette 26 electromotive or for example, by the handle device 34 shown in FIG. 11 can be done. Also a gimbal drive through one along the wing 14 and the outer portion of the same guided Kardansystem is possible, especially when positioning the to be actuated Wing in the upper and inaccessible area of a person Space.

Previous with reference to Figs. 2 to 11 and 12 to 19 Ausstellvorrichtungen for use with tilting wings or Turn-tilt wings have been described, each with a stay include. However, it can be especially heavy and ready Wings are advantageous over the width of the wings away several such Provide extension arms to better distribute when tilting to obtain occurring forces. FIG. 20 shows in its sections a), b) and c) a system in which the display device 18 two Swing arms 38 and 38 'includes. Each of these pivoting arms 38, 38 'is, as previously described, via a respective drive rod section 44 or 44 'controllable for pivoting movement. One recognises in Fig. 20, that the two pivot arms 38, 38 'to each other in opposite directions are positioned and thus at the transition from the closed position in the illustrated tilt-opening position about their respective pivot axes S1 or S1 'on the faceplate 40 or 40' in the Swivel opposite direction of rotation. This requires that the two drive rod sections 44, 44 'for generating the respective Pivoting movement are moved in the opposite direction have to. For this purpose is between the two drive rod sections 44, 44 ', as indicated in Fig. 20 by dashed line, a change gear 180 provided with a toothed shoe 182 in linear displacement engagement can be brought with the drive rod portion 44 'and with a toothed shoe 184 in linear sliding connection with the drive rod section 44 can be brought. In such in Fig. 21 in Side change illustrated change gear 180 is for example the Tooth shoe 182 coupled to a rack member 188, and the Tooth shoe 184 is coupled to a rack portion 186. Between Both rack parts 186, a gear 190 is positioned, which in Change gear 180 is rotatable, but otherwise held stationary. Becomes For example, the tooth shoe 182 moved straight, so is by the Rack portion 186 and the gear 190 and the rack portion 188 this movement in an oppositely directed movement of the tooth shoe 184 implemented.

For actuating or activating the two opening arms 38, 38 ', it is then advantageous, the operating force directly on the To guide gear 190, d. H. for example as described above, through a into a square opening 192 of the gear 190th used square pin to drive this to turn, this Rotation over the two rack sections 186, 188 in opposite directions directed displacement movements of the toothed shoes 182, 184 implemented becomes. These opposing displacements lead to opposing Displacement movements of the drive rod sections 44 'and 44 and to corresponding pivoting of the Ausstellarme 38 ', 38th It should be pointed out that in such a configuration, the two Ausstellarme 38, 38 'with their associated components, which pivoting cause the same, are designed mirror-symmetrically.

It can be seen in Fig. 20 further that the two pivot arms 38, 38 'to respective pivot axes S2, S2 'on the frame, not shown are held pivotally. To such an arrangement in a It is necessary to use the swivel-type tilt-and-turn sash Connection of one of the extension arms 38, 38 'in the region of the pivot axis S2 or S2 'to solve, and then to the other Axis S2 or S2 ', the rotary-pivoting movement of the wing to carry out.

Figs. 22 to 24 show an arrangement with which in the area of Swivel axis S2 'are generated such a release of the rotary joint can. It can be seen in Fig. 22a) the end portion of the stay arm 38 ', which on the bearing sleeve 46 'on a blind frame fixed bearing eye component 194 can be mounted pivotally. For this purpose a bearing rod 196 is provided, which in the illustration b) of FIG. 22 shown to the side of the bearing eye component 194 to the Relative positioning clearly visible. It is however on it indicated that this bearing rod 196 in the bearing eye component 194th and the bearing sleeve 46 'engages to make the pivotal connection. In its other end the bearing rod is 196, as in the Section b) of FIG. 23 can be seen, with a displacement part 198 a Hand operation unit 200, for example by a clamping screw 202, firmly connected. The sliding part 198 is in a blind frame fixed Displacement sleeve 204 in the longitudinal direction of the bearing rod 196 movable. At the sliding sleeve 204 is pivotally mounted a lever 206. This Hand lever 206 has a gear segment configuration 208, which with a rack configuration 210 on the sliding part 198th combs. The portion b) of Fig. 23 shows in accordance with the Section b) of FIG. 22 is a positioning of the hand lever 206 and of the storage bar 196, in which the storage bar 196 both in the bearing eye component 194 and in the bearing sleeve 46 'engages and thus making the pivotal connection about the axis S2 '. Is going out from the representation of FIG. 23b) of the hand lever 206 into that in FIG. 23c). shown pivoted position, this leads to a shift of the Displacement parts 198 down, the fixed with the displacement part 198 coupled bearing rod 196 follows this movement and thereby, as in Fig. 23c) shown, from the bearing sleeve 46 'exits, but in the bearing eye component 194 remains. It is in this state then the coupling of Bearing sleeve 46 'lifted on the frame 12, so that in this Area of the wings 14 is released for rotary pivoting movement. Should again a coupling, so starting from the in Fig. 23c) illustrated positioning of the hand lever 206 in the direction of the Displacement member 198 to be pivoted so that this again in the in Fig. 23b) shown positioning is brought and the storage rod 196 in the in Fig. 22b) slides shown positioning.

It can be seen that in the sliding sleeve 204 on one side an engagement opening 205 is provided, through which the lever 206th can be taken, and in which the handle 206 in the position in which produces a rotary coupling in the region of the pivot axis S2 ' is completely swung in.

To enable the rotation movement around that shown in Fig. 1 vertical axis A2, the tilting bearing 24 must also be solved. This can, as already mentioned above, by the camp 24 itself provided components, but, as follows Referring to Figs. 23 and 24 described, preferably simultaneously with the release of the connection in the region of the pivot axis S2 'made.

It can be seen in Fig. 23 that with the displacement member 198 another Bearing rod 209 is fixedly coupled, which is relative to the bearing rod 196 extends in the opposite direction. In his free end area passes through the bearing rod 209 another bearing eye component 211, the in section a) of Fig. 24 can be seen. Furthermore, points in this free End portion of the bearing rod 209 a flattened portion 212, the however, ends with a re-expanded head 214. This extended head 214 is produced at coupling in the region of the bearing 24 in one circular receiving portion 216 of a set on the wing 14 Tilting bearing component 218, in the lower part of section a) of Fig. 24 can be seen in plan view. In the positioning of FIG. 24 in FIG Section b) engages the extended head 214 in this circular area 216 and forms with this a kind of ball joint. Will however the Hand lever 206 in the positioning shown in section c) of Fig. 23 shifted, the flattened portion 212 of the storage rod 209 enters the circular region 216 of the bearing component 218. The flattened Region 212 is then with a lateral opening 220 in the bearing component 218 aligned. It can now be pivoted the wing so that the flattened portion 212 through the opening 220th passes. If the wing from the rotary opening position weider closed, the flattened portion 212 again enters the opening 220 and the circular area 216, and, after moving the hand lever 206 in the positioning shown in Fig. 23 section b) occurs again extended, head-like region 214 in the circular region 216 and makes together with this again the ball joint-like connection, to allow a tilting operation. It should be noted that instead of the hand lever 206 here again an electric motor Drive can be provided, in which a drive pinion with the Rack configuration 210 meshes.

Furthermore, it can be seen in Fig. 23 that the displacement member 198 has a locking screw 222 may be provided, which in that position, in which a rotational opening operation is not possible, namely in Fig. 23b) recognizable position, with an opening 224 in the sliding sleeve 204th is aligned. By unscrewing the screw 222, this can in the Opening 224 are moved in, so the entire arrangement to block against displacement and ensure that an unwanted Loosening in the two storage areas is prevented.

Figs. 25 to 27 show a configuration in which one of the two in Fig. 20 illustrated Ausstellarme, namely the stay arm 38 ', in Area of its pivot axis S2 'not on an outside of the frame 14 lying bearing is pivotable, but in a storage device 226th is mounted on the inner surface 30 (Fig. 27) of the frame 12th is fixed. This situation is illustrated in FIG. To here too Transition into a turning operation, a connection in the area of the pivot axis S2 'to solve, the device 226 against Preload a spring 228 sliding displacement component 230th on. This sliding component 230 engages between the frame 12 and the wing flap 232 and has a manual operating part 234, along the outer edge of the wing flap 232 against the bias of the spring 228 can be moved. A frame-fixed Part 236 of the device 226 and the displaceable part 230 together form a bearing opening 238 of the device 226, in which a the axis S2 'bildender and with the stay arm 38' firmly connected Bearing pin 240 can be pivotally received. When shifting of the movable part 230 in the illustration of Fig. 27 to the right a passage formed, through which the bearing pin 240 can emerge, so that in the region of the axis S2 'the pivot bearing connection is solved. Is then out of the rotational opening position of the Wing moves back to the closed position, so the bearing pin 240 abuts on a schematically illustrated inclined surface 242 of the displaceable Part 230, moves this part 230 against the bias of the spring 228 in the illustration of FIG. 27 to the right and enters the bearing opening 238, whereupon the part 238 by the spring 228 back into a position is moved, in which the bearing pin 240 securely in the bearing opening 238 is held.

When comparing FIGS. 20 and 25, it can be seen that when combining the Ausstellarms 38 of FIG. 20 with the stay arm 38 'of FIG. 25 the Swivel axes S2 and S2 'are in different levels. The pivot axis S2 'of FIG. 25 lies in a plane E1, which in the closed position approximately with the longitudinal center axis of the extension arm 38 'matches. In contrast, the pivot axis S2 lies in a plane E2 (see Fig. 20), which with respect to the plane E1 by a Offset V is offset in the direction of arrow V. However, since the two Swivel axes S1 and S1 'in the same, through the Faceplate 40 defined level, it is when performing a Tilting movement required to obtain a constraint-free movement the Ausstellarmen 38 and 38 'different deployment angle to compensate for the offset V. This can be, for example be achieved that at the extension arm 38 ', which conditionally requires a larger swing angle by the offset V, one of slot-like openings 90 ', 92' with respect to the longitudinal direction L of Ausstellarms 38 'as indicated by the line S in Fig. 25, inclined is to, as described above, with the same swinging the Arm portion 86 'with respect to the faceplate 40' a larger Kipphub to get. Accordingly, could in the Ausstellarm 38 one of slot-like openings are inclined in the opposite direction to Here to produce a reduced Kipphub. In this way you can a zwängungsfreie tipping the wing can be achieved without to have to make sure that the two the Ausstellarme 38 and 38 ' driving espagnolette sections or transfer plates to each other would have to be configured differently. Nevertheless, it is equally possible by a transfer gear, the two drive rod sections, which the to drive various Ausstellarme move so that they have a perform different displacement stroke. Also it is possible in the field the guideways for the guide projections of the transfer plate of at least one of the extension arms different configurations provide there already different pivotal movements of the two Ausstellarme 38 and 38 'to produce.

Figs. 28 to 31 show an arrangement through which in Figs. 25 to 27 shown device 226 by means of a manual operation device can be controlled. This hand-operated device shown in FIGS. 29 and 30 In its construction essentially corresponds to the already previously described with reference to FIG. 23 described manual actuating device. It comprises a sliding sleeve fixed again on the frame 204, with a sliding part 198 displaceable therein Hand lever 206 again has a tooth configuration 208, which with a rack configuration 210 on the sliding part 298th meshes, so that by pivoting the on the sliding sleeve 204th carried hand lever 206, the sliding part 298 in the longitudinal direction of the Shift sleeve 204 can be pushed up and down.

With the displacement part 198 is an actuating rod 250, for example by a clamping screw or the like, fixed, which, As can be seen in particular in FIG. 28, upwards into that area extends, in which the bearing device 226 is provided. The Displacement rod 250 passes through there a guide component 252 and carries at its free end a Verschiebekeil 254. Also between the wing flap 232 and the frame 12 emerging part 234 of the device 226 has one to the wedge surface 256 of the displacement wedge 254 complementary wedge surface 258 on. When pivoting the hand lever 206 from the position shown in Fig. 30 in the clockwise direction and thereby induced movement of the sliding part 198 and the displacement rod 250 pushes down the displacement wedge 254 by its wedge surface 256th on the wedge surface 258 of the part 234 and shifts this while in the Representation of Fig. 28 to the right. This gives the movable part 230 of the device 226 the bearing pin 240 in the region of the bearing opening 238 free. The wing can then be pivoted in rotary operation. Becomes the hand lever 206 swung back into the position shown in FIG. 30, Thus, the part 234 again in the illustrated in Fig. 28 Return position and the bearing opening 238 is closed again. Subsequent closing of the wing causes the bearing pin 240, the inclined surface 242 of the displaceable part 230 against the Biasing bias of the spring 228 moves so that it returns to the bearing opening 238 can occur.

It should be noted that the return of the hand lever 206 in the shown in Fig. 30 position also by the bias of the spring 228th can be achieved, as these the part 234 in Fig. 28 to the left biased, due to this bias and the sliding wedge 254th and thus biasing the shifting bar 250 in an upward direction become. Again, it should be noted that instead of the Hand lever again a motor drive can be provided.

FIGS. 32 to 34 show, in combination, an opening device 18, in which turn two Ausstellarme 38 and 38 ' are provided. It can be seen that here the two Ausstellarme 38, 38 ' are equal to each other or in the same sense be pivoted. It is thus possible, the two drive rod sections 44, 44 'directly for common movement with each other couple without having to provide a change gear between them. The drive can then via one of the drive rod sections 44 and 44 'or can be done by one with these two drive rod sections 44, 44 'connected drive rod system. at such a configuration is one of the Ausstellarme, namely the stay 38 ', with a different bearing arrangement in the area of his Swivel axis S2 'connected to the frame, as the other of the two extension arms. For this purpose, as can be seen in FIG. 33, again provided the bearing device 226, its structure and operation respectively correspond to those described above. A closer one Description is therefore no longer required. It should be noted that in the over the wing flap portion 234 a Opening 260 may be provided, which for receiving a Bowden cable soul 262 serves, so that over a Bowden cable system again a Remote operation can be done.

Again, it is necessary to different tilting strokes at the same To provide movement of the drive rod sections 44 and 44 ', because the two pivot axes S2 and S2 'again in the one another offset planes E1 and E2 are. For this purpose is the pull-out 38 'again the slot-like opening 90' with respect to Lenght L of the extension arm 38 inclined, so that for the stay 38 'at the transition to the tilted position by the above already detailed bending this Ausstellarms 38 'one to the offset V enlarged tilting stroke can be provided for the wing. Otherwise corresponds to the system shown in FIGS. 32 to 34 substantially described with reference to the preceding embodiments Operating principle.

The present invention provides a display device, which in a simple way by minor adaptation measures the use with a tilting wing or a turn-tilt wing can be adapted. When induced by the display device Swiveling movement of the various extension arms becomes on the one hand achieved that in the closed position a relatively large motive force is present, while in the area of tilting a relatively large Kipphub a wing at a given displacement of a drive rod system is induced. These different states of motion with the previously described power transmission in particular in the vicinity of the Closing position can by the above-described skew of at least one of the guide openings of the telescopic connection the Ausstellarms also be achieved in that this inclined Guideway has a curved course, so for example from a substantially in the longitudinal direction of the extension arm extending portion in a curved or with respect to this Longitudinal inclined section passes. On the other hand sees the present invention the simple coupling of the Ausstellsystems to a conventional, provided at window or door wings espagnolette before, since the normally existing Treibstangenhub, which in the Transition from the closed position to the rotary position in the range of 18 mm can lie and in the transition from the rotational position to tilt position in Range of 18 mm can be sufficient for a sufficient Kipphub to provide for the wing. Should still be the case of a drive rod system existing Verschiebehub not sufficient, so for example between this drive rod system and the drive rod sections the present invention, a motion transmission gear be provided, which is a displacement stroke of the espagnolette system in an enlarged displacement stroke of the drive rod sections, which the Moving display arms in motion, converts.

Furthermore, the system according to the invention provides the possibility that To provide drive both manually and by electric motor, or where appropriate, to provide both propulsion options, so that in case that, for example, the electric motor drive fails, still a Manual operation is possible. It should be noted that in principle also For example, a pressure fluid-operated drive for generating the displacement force can be used for the drive rod sections.

There are described above embodiments, in which the drive rod system is arranged on the wing. Especially when used in conjunction with tilting wings, where a rotary option is not provided, it may be advantageous, in the figures Pictured espagnolette section or Stulpschienenabschnitt provide on the frame and the pivot axis S2 in the region of To relocate wing. It can then also the drive frame side take place, so that it is not necessary when using an electromotive Drive lines leading into the area of the wing. Also can then the electric motor drive are provided on the frame and does not have to be tilted together with the wing. Also with this Ausgestaltungsform it is possible on the espagnolette then Schließkloben to be provided, which with positioned on the wing strike plates or Closing traps help to lock the sash to the frame.

The accompanying drawings show that in the field of different pivot or sliding connections, d. H. for example in the field of telescopic connection 98 or in the field of Bearing connection of the bearing pin 240 each created a possibility is that the components stored next to each other not only a pivoting or guiding movement, but also a twisting motion with respect to each other. This is especially in the area Ausstellarms 38 advantageous, which both a telescopic movement should perform, as well as by the tilting occurring during tilting the two pivot axes S1 and S2 wound in relation to each other in itself must become. Due to the crowned design of the various Bearing or guide pin 94, 96 and 240 is a allows such additional tilting or twisting movement. Further can all bearing parts provided in the region of the pivot axes S2 face down, d. H. can be included in the rebate air or be covered by the wing flap.
