Description

The present invention relates to a display device for a a tilt or turn-tilt sash attached to a frame, in particular window casements or door casings, comprising at least one Extension arm, which on the wing about a first pivot axis and on Frame attached to a second pivot axis or can be attached, a drive device on the wing or on the frame with a by a drive displaceable drive unit, at least one an extension arm assigned transmission arrangement through which a Sliding movement of the drive unit in a pivoting movement of the assigned deployment arm can be implemented, the transmission arrangement tion comprises a transmission element which is connected to the drive unit by one third pivot axis is pivotally attached and that when shifting the drive unit is pivoted about the third pivot axis, the Transmission member engages the extension arm and this around the first or pivoted second pivot axis.

From DE 33 45 870 A1 an opening device is known, in which the transmission link in an end region by a wing-side Drive is relocatable and in its other end area with one Display arm cooperates. With an extension arm on Wing-articulating auxiliary arm moves the transmission link and a pivotal movement of the same, which is thereby generated, means that the extension arm swivels with respect to the wing and thereby the wing for example, starting from a closed position into a tilted position is pressed. The link and the pivot Extension arm in opposite directions, with the result that one between the extension arm  and the angle formed by the transmission member with increasing approach an angle of 90 ° approaches the tilt-open position. The means that with increasing transition to the tilt position one leads Displacement of the transmission link induced pivoting of the same to a progressively smaller assigned pivoting of the Extension arm. This has the disadvantage that especially in the initial phase an opening movement of a tilt window or the final phase a closing movement of the tilt window a linear displacement of the Transfer member to a relatively large assigned pivot movement supply arm and thus, for example, a window the consequence that especially in this movement phase, in which the Opposing forces are greatest, only a very great low power transmission can be achieved.

There is also an exhibition from German Ausleschrift 1 708 852 direction known for windows or doors, in which at Carrying out opening or closing operations of the transmission link and the extension arm, pivot in the same sense. With this movement however, both move the pivot axis of the transmission link as well as the pivot axis of the extension arm with respect to the wing which also induces the displacement of the transmission link Drive device is provided in the same direction, also with the consequence that the displacement of the transmission member is compulsory induced pivoting of the same in the initial phase of an opening movement tion or the final phase of a closing movement to one leads relatively large tilting stroke with a correspondingly low tilting force.

Furthermore, these known display devices have the disadvantage that to obtain a desired position of the extension arm, d. H. one desired tilting strokes of a wing with respect to a frame, a relative extensive linear displacement of the drive unit is required, especially if the required opening and opening is also required  Closing forces are to be provided, with the result that it is, for example is difficult, the shift drive for the transmission arrangement with a sliding drive for others, for example on the wing seen coupling elements to couple, which generally only one require a relatively small stroke.

It is the object of the present invention to provide an opening device for a tilt or turn-tilt mounted on a frame To provide wings through which improved tilting force ratios low adjustment stroke of a drive unit can be achieved.

According to the invention, this object is achieved by an opening device for a tilt or turn-tilt mounted on a frame Casement, in particular window casement or door casement, comprising at least an extension arm, which on the wing about a first pivot axis and on Frame attached to a second pivot axis or can be attached, a drive device on the wing or on the frame with a by a drive displaceable drive unit, at least one an extension arm assigned transmission arrangement through which a Sliding movement of the drive unit in a pivoting movement of the assigned deployment arm can be implemented, the transmission arrangement tion comprises a transmission element which is connected to the drive unit by one third pivot axis is pivotally attached and that when shifting the drive unit is pivoted about the third pivot axis, the Transmission member engages the extension arm and this around the first or pivoted second pivot axis.

In the display device according to the invention it is further provided that with the display attached to the sash or frame direction of the first and the second pivot axis with respect to the wing or of the frame are essentially fixed and that at Swiveling the at least one extension arm out of a lock  position of the wing assigned first pivot position in the direction of a a tilt-open position of the wing assigned second pivot position the third pivot axis by moving the drive unit in the direction ver to a pivot axis of the first and second pivot axis is pushed about which pivot axis the extension arm on that Assembly of sash and frame pivotally attached or attachable on which the drive device is provided or is to be provided.

The measures of the present invention ensure that in defined Way by moving the transfer link to the Swivel range of the extension arm - which goes hand in hand with the fact that the the transfer link provided pivoting effect in a closer to Pivot point of the extension arm lying area is effective - initially when it is relatively far from the pivot point of the extension arm Pivot point of the transmission link a displacement and swiveling Kung the same only a relatively small pivoting the arm induced. That means, especially in the initial phase of the opening movement of a wing leads to a predetermined adjustment stroke of the drive unit a relatively small swing angle of a wing, which ent speaking power transmission results. However, approaches in the course the pivoting movement of the pivot axis of the transmission member to the corresponding pivot axis of the extension arm, the over support member forcibly in an area closer to the extension arm effective, so that due to the shortened leverage ratios given displacement stroke of the drive unit to a significantly larger Swivel angle of the extension arm and thus a significantly reinforced one Tilting movement of the wing leads. The same applies vice versa Transition from an open or tilted position of a wing to one Closed position, initially due to the close to the pivot axis the pivot arm of the transfer link Displacement of this transmission link is initially a relatively large Angular movement of the wing is induced, and when approaching the  Close position of the same shift stroke significantly reduced Causes tilting movement, with the result that a wing, for example effectively tilted against a counterforce generated by a wing seal can be.

Furthermore, the display device according to the invention has less Overall width as a result of the closer to the pivot point of the Aus actuating arm effective transmission link a significantly larger Swing stroke of this extension arm can be achieved, with the result that for example the displacement movement of the pivot axis of the over support member to a displacement movement of a conventional Espagnolette system can be coupled in a window sash.

The expression "when attached to the wing or frame Display device "should make it clear that the respective pivot axes or the com defining these swivel axes components after attaching the system according to the invention with respect The frame or sash cannot be moved. That is, the Swivel axes can each be defined or formed by components, which are fixed to the frame or sash.

The drive unit can preferably have at least one through the drive comprise in the longitudinal direction displaceable drive rod.

In particular when using the display device according to the invention in areas that are difficult to access, e.g. B. when used as skylights, it is advantageous if the drive is an electric motor drive with a Relocation gear arrangement, by means of which a rotary movement of a Motor component in a linear displacement movement of the drive unit is feasible.  

Alternatively or as an auxiliary drive, however, it is also possible for the drive comprises a manually operable drive, preferably with a rotatable handle and the rotational movement of the handle in one Linear shifting movement of the conversion unit converting the drive unit order.

According to one aspect of the present invention, the mentioned pivoting movements the transmission arrangement include: one between the transmission link and one with respect to the a first guide component acting a pivot axis Guideway arrangement with a first guideway in the guide component or the transmission link and one when the Drive unit can be guided along the guideway on the guide part each other component of management component and transfer member, the guideway of the first guideway arrangement at least in some areas with respect to the direction of displacement of the drive unit runs diagonally.

It is also used to implement the displacement movement of the drive unit advantageous in a pivoting movement of the extension arm if the Transmission arrangement further comprises: one between the transmission member and the extension arm acting second guideway arrangement a guideway in the transmission link or in the extension arm and one when the drive unit is moved along the guideway Guide part on the other component of the transmission link and Extension arm, preferably the guideway of the second guide track arrangement at least in regions with respect to a longitudinal direction of the extension arm runs obliquely.

Through the inclined guideways it is achieved that at forced movement of a guide part a swiveling movement of at the same time along the guideway  at least one of the components that relate to the guideway wise carry the guide part is induced.

To get the movement translation mentioned at least in the Final phase of a tilting movement, it is advantageous if, for example, the Guideway of the first guideway arrangement and the guideway the second guideway arrangement in its inclined Range run such that when the drive unit is moved to Swiveling the extension arm in the direction from the first swivel position the second swivel position with the extension arm about the first swivel axis swivels a larger swivel angle than the swivel angle which the transmission link in this movement by the third Swivel axis swiveled.

This can be achieved, for example, in that the guideway of the first guideway arrangement and the guideway of the second Guideway arrangement starting from an area in which the guide parts assigned to respective guideways in the first Extending arm are located in the direction of displacement of the Drive unit converge at least in some areas or run away from each other.

As already mentioned, according to a preferred type of use Display device according to the invention in connection with a convention tie rod system on a window sash or a door sash be used. Such drive rod systems are so-called Locking block slidable, which after passing a predetermined Push the sliding path out of the corresponding latches and thus the Release the sash for pivoting or tilting movement. So since starting from in a closed position, the latches must first be moved, without the wing being forced to tilt, and only after the locking block has emerged from the associated locking latch  len and further movement of the drive rod system the tilting movement may be induced, is according to a further aspect of the invention proposed that the guideway of the first guideway arrangement or / and starting the guideway of the second guideway arrangement from an area in which this is assigned to the respective guideway Nete guide part with the extension arm in the first swivel position lies, one along the direction of displacement of the drive unit as the longitudinal direction of the extension arm extending first section has and subsequent to this first section with respect to Direction of displacement or the longitudinal direction obliquely has second section.

Since according to the invention the at least one extension arm both on the frame as well as on the wing around fixed, so not with regard to these modules displaceable or essentially non-displaceable axes pivotable should be, it is advantageous if in order to enable the length compensation in the Area of the extension arm when performing a tilting movement of the at least one extension arm has a first arm section and a second Has arm section, which with respect to each other essentially in one Arm longitudinal direction are telescopically displaceable.

For this purpose it can be provided, for example, that on one of the arm sections at least one guideway is provided, along which a other arm portion provided guide part is displaceable.

It can also be provided that at least two guideways are provided and that one of the guideways with respect to another Guideway runs diagonally. Such an embodiment has the advantage with the result that the transmission arrangement in a predetermined Condition with respect to the opening arm held by the frame or sash and by tilting one of the guideways of the telescopic connecting the two arm sections makes an additional contribution to  Tilting stroke of the wing can be delivered, depending on the slope position of this guideway this additional stroke contribution to the normal existing tilting stroke is added or subtracted from this is.

When used with a tilt and turn sash, the telescopic connection would have between the two arm sections of the at least one extension arm with the result that when changing from the closed position to a rotary opening position in the upper area of the wing, in which such an exhibition device is generally provided through which is essentially free telescopic connection of the two arm sections a lack Bracket of the wing would be provided with respect to the frame. It will therefore proposed to provide a bridging arrangement by which in the first swivel position of the extension arm the telescopic Bridged connection between the first and the second arm section is.

Especially with larger and heavier wings, it is advantageous if at least two extension arms with each of these assigned over support arrangements are provided. These can then be across the width of a wing can be positioned distributed.

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

To this opposite pivoting of the two arms get through which ultimately an even better distribution of forces over the width of a wing can be achieved, it is proposed that everyone of the at least two extension arms a drive unit of the drive unit Direction is assigned and that the the at least two arms  assigned drive units in opposite directions to each other by the drive are movable.

This opposite displacement movement of the two drive units can for example by one acting between the two drive units Change gear arrangement can be achieved. In this case it is advantageous if to operate the display device according to the invention, d. H. to the Tilting a wing, the drive on the movement implementation in the Actuating component acts. So it's one central force transmission is provided, through which to both sides 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, the change gear is a device through which both drive units in different direction to Ver sliding movement are driven. The one causing the implementation The component is then the drive component.

Should also be used for an opening device with several opening arms Rotary operation of the assigned wing be possible, it is advantageous if at least one of the extension arms in the region of the second swivel axis is detachably coupled to the frame or can be coupled. It will be on this way the one in the two corner areas, for example Wing provided coupling of the extension arms to the frame solved on one side, so that the wing then about the second pivot axis of the off lying in the other corner or coupled to the frame arm can pivot.

Here it is advantageous if a decoupling device is provided, through which the rotary coupling of at least one of the extension arms the frame is detachable in the region of the second pivot axis.  

Should a wing be used both in turning and tilting operations must be ensured that in the tipping mode in the lower edge area of the wing at least two bearing points are provided, around which the Wing can tilt, and that at least when swinging the wing two pivot points located on one side edge of the wing are provided, around which a pivoting movement can take place. If multiple extension arms are provided and to enable the Swivel movement the swivel coupling of one of the swivel arms must be solved on the frame, then it is advantageous if by the Decoupling device also when decoupling the arm from Frame in the region of the second pivot axis a tilt bearing arrangement is releasable, through which the wing on the frame to carry out a Tilting movement is pivotally attachable or attached.

Furthermore, can be provided in the display device according to the invention be that the at least two extension arms when pivoting from the first pivot position in the same direction in the direction of the second pivot position be pivoted.

When using several extension arms on one wing, it can be necessary, the frame-side couplings of the same in ver different levels. That is, a condition can occur in which the second pivot axis of one of the extension arms with respect to the second pivot axis of another of the extension arms essentially in is offset in a direction in which when a respective Extension arm from the first swivel position to the second swivel position the first and the second pivot axis move away from each other. Would in in such a case, two extension arms acting in the same way are used the offset of the two second swivel axes of the Extension arms for a squeeze in the area of the wing at the transition from the closed position into the tilt-open position. To do this avoid, it is also proposed that when moving from the first  Swivel position to the second swivel position by the one arm provided tilting stroke with respect to one by the other extension arm prepare tilting strokes for the offset between the respective ones Corresponding pivot arms assigned to corresponding second pivot axes Amount is increased or decreased. It should be noted that according to which direction the offset is, i.e. H. with regard to the Tilting movement forward or backward, in a corresponding manner one of the swivel arms has a reduced or an enlarged swivel hub must be provided.

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

In a particularly easy to set up and practical configuration tion form the drive device is provided for attachment to the wing. In this case, the advantage already mentioned can be achieved that each drive unit of the drive device with a drive rod arrangement Coupled on the wing that can be coupled or part of the drive rods arrangement forms.

To obtain a large swivel angle with a small displacement stroke Drive unit can be provided that the transmission member and assigned extension arm due to the displacement movement of the drive unit are pivotable in the same direction.

According to another independent aspect of the present invention is the task mentioned above by a display device for a tilt or turn-tilt mounted on a frame  Sash, in particular window or door wing, solved, which comprises: at least one arm, which on the wing about a first pivot axis and on the frame pivotable about a second pivot axis brings or attachable, a drive device on the wing or on Frame with a drive unit displaceable by a drive, a the transmission arrangement assigned to the at least one extension arm, through which a displacement movement of the drive unit in a Pivotal movement of the associated arm can be implemented and through which the extension arm with respect to that assembly of frames and wings on which the drive unit is attached or to be attached, is stable in a predetermined angular position.

According to the invention it is then further proposed that the at least one Extension arm has a first arm section and a second arm section comprises, which are together substantially in an arm longitudinal direction are telescopically connected, when performing a telescopic movement tion of the two arm sections with respect to each other, the first and the second Arm section are forced to be inclined with respect to each other.

Due to the force induced when the telescope movement occurs Tilting of the two arm sections and the one provided defined positioning of one of the arm sections opposite the Frame, or the wing, can, as stated above, a additional contribution to the swivel angle of the extension arm can be delivered, so that by a predetermined displacement stroke of the drive unit larger pivot angle of a wing can be achieved.

It goes without saying that such a configuration with the Advantageous embodiments described above, in particular the movement of the pivoting range of the transmission link on the Swivel range of the extension arm can be combined, so that here  another synergetic effect of these two individually beneficial effects can be achieved.

The present invention further relates to a tilt window or turn-tilt Windows, especially skylights, with a Ausstellvor invention direction and / or a turn-tilt door with an inventive Display device.

Fig. 1 shows schematically a front view of a tilt and turn window 10 in which a stay mechanism according to the invention may be employed. The tilt and turn window 10 includes a stationary frame 12 and a window frame 12 with respect to the both rotatable and tiltable wing or sash fourteenth On an upper horizontal beam 16 of the wing 14 , the Ausstellvor device 18 , which is described in detail below, is attached, which is articulated at the other end in a pivot bearing 20 on the frame 12 . In the lower right corner, the wing 14 is mounted via a corner bearing 22 with respect to the frame 12 both tiltable about a horizontal axis A1 and pivotable about a vertical axis A2. At the lower left corner, the wing 14 is pivotally attached to the frame 12 via a detachable tilt bearing 24 on the frame 12 .

In a manner known per se, a drive rod system 26 indicated by a dashed line is provided on the wing 14 , which can move a plurality of locking blocks 28 which, depending on the movement position, can interact with locking plates or locking latches (not shown) on an inner surface 30 of the frame 12 before seen, to lock the wing 14 with respect to the frame 12 . The driving rod system 26 has, in a manner known per se, respective corner deflections 32 and can be driven, for example, by a handle 34 which, when pivoted in the direction of the arrows shown in FIG. 1, can drive the connecting rod system 26 to move via a gear rack mechanism. Alternatively, as described below, an electromotive drive 36 can be provided, which can also convert a rotary movement into a linear displacement movement of the drive rod system 26 , for example also via a toothed rack and pinion drive, in order to thereby move the locking block 28 and, as described below, the opening device 18 to control the tilting of the sash or sash 14 .

FIG. 2 shows a top view of such an opening device 18 . This includes a generally designated 38 arm, which is pivotally attached in an end region on a faceplate 40 about a pivot axis 51 , the pivot axis 51 being a substantially vertical axis in the closed state of the window. This faceplate 40 is mounted in a conventional manner on an outer circumferential surface 42 ( Fig. 1) of the wing 14 and hides the drive rod system 26 lying in a sash groove, of which a drive rod section 44 lying under the faceplate 40 is indicated by dashed lines in Fig. 2 . The opening device 18 then lies essentially in the rebate air between the surfaces 42 and 30 of the wing 14 or the frame 12 .

In its other end region, the raising arm 38 is connected to a bearing sleeve 46 of the rotary bearing 20 which can be seen in FIG. 20.

A recognizable also in FIG. 8 is to guide the face plate 40 also fixed plate 48, 48 of the extension arm 38 rotating overlapping stud or rivet is used to fix the guide plate 50, and the other end, a separate fastening stud or rivet 52nd It should be noted that a sliding bearing part, for example a Teflon part 54 , can be positioned between the guide plate 48 and the extension arm 38 for easier pivoting.

The guide plate 48 has two slot-like openings, one of which is closer to the pivot axis S1, designated 56 , and extends essentially rectilinearly in the longitudinal direction of the faceplate 40 , ie in the circumferential direction, and the other, designated 58, is further away from the pivot axis S1 . The elongated hole-like opening 58 has a first section 60 which extends essentially in a straight line in the circumferential direction, a curved transition region 62 and a second section 64 which is inclined with respect to the circumferential direction.

The slot-like opening 56 passes through a fastening bolt or rivet 66 which is fixed on the one hand to the drive rod section 44 and which on the other hand carries a transfer plate 68 above the guide plate 48 about an axis S3 which is fixed with respect to the drive rod section 44 but can be displaced in the circumferential direction in a straight line. In its end region remote from the pivotable attachment to the drive rod section 44 , the transmission plate 68 has a guide projection 70 in the form of a bolt or rivet, which extends downward with respect to the transmission plate 68 and engages in the slot-like opening 58 . That is, the elongated hole-like opening 58 forms with its two side surfaces 72 , 74 a guideway for the guide projection 70 on the transmission plate 68 .

Laterally offset with respect to the guide projection 70 , a further guide projection 76 is provided on the transmission plate 68 , but which extends in the opposite direction, ie upwards, and engages in a slot-like opening 78 in a widened area 80 of the deployment arm 38 . The elongated hole-like opening 78 in the actuating arm 38 has two sections, namely a section 82 which is further away from the pivot axis S1 and which is substantially parallel to the longitudinal direction L of the actuating arm 38 and a first section 82 which follows a transition region 83 , the pivot axis S1 closer second section 84 , which is inclined with respect to the longitudinal direction L.

It can be seen in FIGS. 2 and 3, further, that the opening arm 38 is constructed of two arm portions 86, 88. The arm portion 86 is pivotally attached to the faceplate 40 , and the arm portion 88 supports the bearing sleeve 46 and is pivotally attached to the panel frame 12 about the axis S2. One of the arm sections, namely the arm section 88 , has two slot-like openings 90 , 92 , in which guide bolts 94 , 9.6 fixed on the arm section 86 can be guided essentially in the longitudinal direction L of the deployment arm 38 . In this way, a telescopic connection 98 is created in the transition region between the two arm sections 86 , 88 , which, when a tilting movement is carried out, compensates for the length of the axles S2 and S1, which are essentially fixed with respect to the frame 12 and the sash 14 allow hinged extension arm 38 . It should be noted that to assemble the two arm sections 86 , 88, the elongated holes 90 , 92 each have enlarged end regions 100 , 102 through which heads of the guide bolts 94 , 96 can be passed. However, a position in which the heads of the bolts 94 , 96 are aligned with these expanded sections 100 , 102 does not occur during normal operation of a window in order to avoid that the two arm sections 86 , 88 are unintentionally released from one another.

As already mentioned above, a gear rack arrangement, which can be seen in FIG. 3, is used to actuate the opening device 18 . This comprises a plurality of recesses 108 on the drive rod section 44 , which together with the webs 110 separating the recesses 108 form a rack-like formation. Furthermore, a wheel 114 provided with external teeth is rotatably mounted in a carrier 112 and has an internal square opening 116 . In this inner square opening 116 , for example, a square rod of a handle, which will be described below, can be inserted in order to drive the wheel 114 for rotation and thus the drive rod section 44 for displacement, or, for example, a worm or gearwheel can be arranged on the square rod, which is connected to a The worm or gear of a rotary shaft of the electromotive drive 36 of FIG. 1 meshes, so that the drive can take place by an electric motor. In particular in the case of an electric motor drive, it can also be provided to assign a conversion gear to this drive, which converts a rotary movement of the rotor into a linear displacement movement, for example also via a worm gear, in which case, for example, two projections at a distance from one another can form a receiving opening on the connecting rod section 44 . into which a driver of the linearly displaceable component of the transmission engages in order to shift the drive rod section 44 .

The function of the opening device according to the invention is described below, in particular with reference to FIGS. 7, 9 and 10. It should be understood first by the Fig. 10, which actuator arm from a position of 38 and the visible portion there are again the same 86, which corresponds to a closed position of the wing 14. Z. This means that in this position the extension arm 38 is essentially congruent over the faceplate 40 . This is a position in which the drive rod section 44 is pushed to the right to a maximum extent, so that the two guide projections 70 and 76 are located in the end region of the section 60 and 82 of the respective slot-like openings or guideways 58 , 78 extending in the longitudinal direction of the faceplate. In this position, the Ausstellvor device 18 itself provides a lock, because even by exerting a tilting force on the wing 14 , for example by wind, the guide projections 70 , 76 can not be moved in the sections 60 , 82 . It can also be seen that the sections 60 , 82 of the slot-like openings 58 , 78 are laterally spaced and are each positioned close to a lateral end region of the guide plate 48 or the widened section 80 of the extension arm 38 . After their respective curvature regions 62 , 83 , the openings 58 , 78 then extend obliquely to the faceplate longitudinal direction to the other lateral end region of the guide plate 48 or of the enlarged section 80 of the extension arm 38 . In this way, as can be seen below, the greatest possible pivoting efficiency is achieved with a minimal lateral width. However, it should be noted that the two slot-like openings 58 , 68 can have other lateral positions relative to one another. This is possible above all because they are not provided in the transfer plate 68 , but in different components.

If, starting from the positioning shown in FIG. 10, the drive rod section 44 is shifted to the left by the drive, ie either a handle 34 or an electromotive drive 36 , the extension arm 38 does not initially move until the curved sections 82 , 83 are reached with respect to the faceplate 40 . With this shift, however, the locking block 28 of the drive rod system, which is coupled to the drive rod section 44, can be guided out of their respective striking plates or latches. However, as long as the locking block is still in interaction with the associated locking latches, pivoting or tilting of the leaf 14 must not occur. After reaching the curvature sections 62 , 83 , however, the locking block 18 is no longer in engagement with the associated locking latches, and after passing through this recognizable in Fig. 9 positioning of the guide projections 70 , 76 , the pivoting movement of the extension arm 38 can begin.

If the guide projection 70 now moves into the inclined section 64 of the opening 58 , as can be seen in FIG. 7, the continuing displacement of the drive rod section 44 and the associated displacement of the pivot axis S3 of the transmission plate 68 in the direction of the pivot axis S1 of the actuating arm 38 for a pivoting movement of the transmission plate 68 with respect to the faceplate 40 and thus the wing 14 . This Schwenkbe movement of the transfer plate 68 about the axis S3 is also transmitted to the extension arm 38 through the guide projection 76 . However, since the guide projection 76 runs in the obliquely extending section 84 of the opening 78 , a pivoting movement of the deployment arm 38 with respect to the transmission plate 68 is additionally forced, but in the same pivoting direction. Ultimately, therefore, the transmission plate 68 with its two guide projections 70 , 76 forms a wedge which, when the swivel axis S3 approaches the swivel axis S1, is forced between the two surfaces or wedge surfaces 74 , 118 formed by the openings 58 and 78 and thereby the extension arm 38 of the faceplate 40 swings away. However, since the two guide projections 70 , 76 extend in different directions, the two wedge surfaces 74 , 118 do not necessarily have to converge in a wedge shape, they could also run away from one another, as is indicated in FIG. 7a. There, too, a movement of the two guide projections 70 , 76 in the direction of the arrow causes the guide projection 70 to be displaced upward along the guideway formed by the opening 58 and that the guideway 78 also moves upward as a result of the guide projection 76 also shifting upward is displaced, which is further reinforced by the fact that the guide projection 76 moves along the inclined portion of the guide track 78 .

This principle of operation has several advantages. On the one hand, it can be seen that through the two inclined web sections an induced by linear displacement of the drive rod section 44 displacement movement of the pivot axis S3 and thus the transmission plate 68 is implemented in an even larger pivoting movement of the extension arm 38 about the pivot axis S1 and thus also the pivot axis S3. This is particularly important when the fiction, contemporary display device 18 is to be used in conjunction with a normal drive rod system. In such drive rod systems, the displacement stroke of the respective drive rod sections is essentially predetermined, wherein a first part of the displacement stroke, as mentioned above, is required to release the locking engagement of the locking block with the associated locking latches, and only the second part of the displacement stroke can be used for this to cause a pivoting movement of the extension arm. This means that this relatively small displacement stroke must be converted into the largest possible pivot stroke and thus tilt stroke of the wing 14 . A further advantage of the stay device according to the invention that the by the wedge-like action transfer plate 68, which the pivot axis approaches with increasing swiveling the opening arm 38 of the same S1, starting from the closed position first of all the points of the opening arm 38 on the one hand and on the stulpschienenfesten guide plate 48 on the other hand by Swivel axis S1 are relatively far away. That is, a displacement stroke of the pivot axis S3 with a predetermined amount leads to a relatively small pivoting of the extension arm about the pivot axis S1. However, the pivot axis S3 approaches the pivot axis S1 in the course of the displacement movement of the connecting rod section 44 , so the interaction points, defined by the guide projections 70 , 72, approach the pivot axis S1. A displacement stroke by the same amount therefore inevitably leads to a significantly greater pivoting movement of the raising arm 38 , which is further supported by the respective inclined surfaces of the openings 58 , 78 which form the guideways. However, this means that relatively large forces can be provided in the area of the closed position at the beginning of an opening movement or at the end of a closing movement, for example in order to be able to deform existing seals on the frame 12 or on the sash 14 .

It should be noted that the system described above with reference to FIGS. 2 to 10 is particularly suitable for use with tilting wings, such as. B. skylights provided in larger halls. Since a rotational position is not required here, the tilting bearing 24 ( FIG. 1) can also be a permanently coupled bearing, and when designing the respective slot-like openings 58 , 78 , the straight section 60 or 82 can be made relatively short, with the advantage that the inclination of the inclined section 64 or 84 with respect to the direction of displacement of the drive rod section 44 (in the case of section 64 ) or with respect to the longitudinal direction L of the extension arm 38 (in the case of section 84 ) can be kept small with the same total extension length. This in turn means that there are more favorable force ratios for moving the wing.

In Fig. 2 is indicated with a dashed line S that one of the guide openings 90 or 92 could be inclined with respect to the longitudinal direction L of the extension arm 38 . The inclination of this guideway 98 would result in the fact that during the telescopic movement of the two arm sections 86 , 88 with respect to one another during the tilting process, they are forcibly guided into an inclined position with respect to one another, which is illustrated schematically in FIG. 2a. Since the arm section 86 is held by the transmission plate 68 in each displacement position of the drive rod section 44 in a predetermined angular position with respect to the faceplate 40 and thus the wing 14 , the additional tilting of the two arm sections 86 , 88 leads to the fact that compulsorily with respect to one in FIG. 2a dashed line configuration of the extension arm 38, an additional tilt path W can be obtained. This measure alone can therefore be used independently of the above-described mode of operation in the area of the transmission plate to convert a predetermined displacement stroke of a drive rod section into an enlarged pivot stroke of the extension arm or of the tiltable wing.

It should also be pointed out that the raising arm 38 can also have more than the two arm sections shown, that is to say for example three arm sections, two of which can each be telescopically connected to one another in the manner described above. Even in such a configuration with a plurality of arm sections, the inclination of a guideway can then be provided at least in the region of one of the telescopic connections in order to obtain the above-mentioned effect.

FIG. 11 shows a handle device 34 which can be used to control the system described above. The square rod 122 can be seen , which can be connected to the toothed wheel 114 described above for common rotation. The square rod 122 is rotatably supported by a bearing arrangement 124 on a support unit 126 which can be attached to the wing 14 . It also extends through a square opening 128 in the handle part 130 and carries at its end a cap 132 serving as a push button. A spring 134 is supported on this cap 132 , which at the other end presses on the handle part 130 and prestresses it in the direction of the carrier unit 126 , since the bearing arrangement 124 makes the square rod 122 rotatable with respect to the carrier unit 126 , but not displaceable in its longitudinal direction is held. Around the rotatable mounting of the square bar 122 around the support unit 126 has several z. B. conical recesses 136 , which are preferably arranged at a uniform mutual distance in the circumferential direction around the square bar 122 around. On the handle part 130 , a corresponding number of z. B. conical projections 138 are provided which have the same relative distance as the recesses 136 . By spring 134 , the projections 138 are biased towards the recesses 136 , so that with suitable relative rotational positioning between the handle part 130 and the carrier unit 126, the projections 138 engage in the recesses 136 and thus provide a rotation lock for the handle part 130 .

If the handle portion 130 are moved, it is possible, by grasping it with the fingers of one hand and supporting the thumb on the cap 132, the handle part can be pulled away 130 from the carrier 126 against the bias of spring 134, so that the projections 138 from the recesses 136 emerge. The handle part 130 can then be pivoted to actuate the opening device 18 described above and can be released again after reaching a desired tilting position of a wing, so that the projections 138 engage again in the recess 136 and hold a wing in the predetermined tilted position by the latching thus formed. Due to the conical configuration of the recess 136 or the projections 138 , the actuation can also be carried out exclusively by rotation, the spring 134 then being compressed first by sliding the respective conical surfaces against one another and then when the handle part 130 is rotated after the next relative alignment of the projections 138 has been reached the recesses 136 are locked again. It should be noted that an opposite situation is also possible, ie the projections could be provided on the carrier unit 126 . It is also not necessary to provide as many projections 138 as recesses 136 are provided. It is only necessary to ensure that the number of recesses is at least as large as the number of jumps before. However, the numbers should be the same in order to obtain the most stable rotation lock possible. It should be pointed out that, in particular when using an electric motor drive, the maintenance of any intermediate position can also be achieved in that the conversion of a rotary movement of a motor component into a displacement movement of the drive rod section 44 is carried out by a self-locking conversion gear.

Figs. 12 to 19 show a modification of the stay device according to the invention, which is particularly suitable for use in rotary tilting wings. The basic structure corresponds to the structure described in detail above, so that no further explanation is given here. However, it should be noted with reference to FIGS. 15 to 17 that when used with a turn-tilt sash, the respective rectilinear opening sections 60 , 82 of the slot-like openings 58 , 78 must be extended with respect to the use with tilt sashes, with the consequence that the inclined sections 64 , 84 , which lie between the rotational position D and the tilting position K, are shorter and therefore have to have a greater inclination with respect to the respective straight section in order to obtain the same tilting stroke. This configuration is due to the fact that in the transition from the position Z, which corresponds to the closed position, to the rotary position D, a larger stroke is required in order to bring the locking block into a position which enables the leaf to rotate about the vertical axis A2 allowed. Otherwise, the straight section is also required in this embodiment for the two openings 58 , 78 , in order first to enable the release of the locking block without already induced tilting movement, and then after passing through the rotary position by means of the previously described effect, the raising of the raising arm 38 to get the sloping sections. It should be noted in this connection that for obtaining the Schwenkbe it movement of particular advantage is that for example in the slot-like opening 58, a lateral displacement between the pivot axis 52 and that surface area of the guide track is provided on which the guide protrusion 70, supports. The same applies to the lead projection 76 .

For use with a tilt and turn sash, it is necessary to ensure that the telescopic connection 98 between the two arm sections 86 , 88 is not effective during the turning operation. It would then be because of this telescopic connection, a lack of fixation of the wing in the upper area with respect to the frame 12 . For this purpose, a bridging arrangement 140 is provided, which, on the faceplate 40, comprises a bridging bolt 142 , and on the arm section 88 , which is pivotally mounted on the frame 12 about the axis S2, comprises a bridging shoe 144 . Is the opening arm recorded 38 in the example in Fig. Closed position 17 shown positioned in which the arm portion is located 88 via the face plate 40, then the lock pin 142 in the shoe 144 and through the two in the longitudinal direction of the arm portion 88 from lying isolated sections 146, 148 of the bridging shoe 144 , a relative movement of the faceplate 40 with respect to the arm portion 88 in the faceplate longitudinal direction and thus in the longitudinal direction L of the deployment arm 38 is not possible. The wing 14 can then be moved in the direction of rotation by bridging the telescopic connection 98 . For this purpose, however, it is still necessary to release the tilt bearing 24 which can be seen at the bottom left in FIG. 1. This can be done, for example, by manually actuating a release lever on the tilt bearing 24 in order to move a bearing pin out of a bearing eye. If a tilting operation is to take place again, the bolt must be moved again into the bearing eye by repositioning the lever in order to provide a defined mounting of the wing 14 with respect to the frame 12 in this area as well. At the transition to the tilt position, the bridging bolt 142 then emerges from the bridging shoe 144 , so that the arm section 88 and the faceplate 40 can be moved freely with respect to one another.

It can also be seen in FIGS. 12, 13 and 14 that an additional locking arrangement 150 can be provided in the region of the pivot bearing 20 ( FIG. 1). This latch assembly 150 for example comprises an extension section 152 for the driving rod portion 44, which bar-section with a tooth shoe 154 in a known manner in the sliding coupling with a gear portion 156 at the propellant 44 can be brought. Furthermore, the locking arrangement Ver 150 includes a faceplate section 158 which can be fixed to the wing. A bearing bolt 160 , which carries a further locking block 162 , slidably passes through this faceplate section 158 . On the arm section 88 , a locking latch 164 is provided for the locking block 162 , which can move the locking rod section 152 in the longitudinal direction in an opening area 166 to accommodate the locking block 162 and then secures it in the lateral direction against movement with respect to the arm section 88 . The locking latch 164 used to accommodate the locking bolt 162 is pivotally mounted on the arm section 88 via a rivet 168 and has an eccentric arrangement 170 in order to suitably position the locking latch 164 with respect to the arm section 88 when the locking block 162 enters the opening 166 to clamp against the frame 12 before.

Fig. 19 shows a different type of configuration of the slot-like openings or guide tracks 58, 78. It can be seen that a significantly larger radius of curvature of the guideways thus formed is provided in the transition regions 62 , 83 , so that the transition from the rectilinear to the inclined sections is smoother and thus enables easier actuation. The radius of curvature of these transition regions 62 , 83 should in any case be in a range which is greater than the radius of curvature of the guide projections 70 , 76 , and is preferably in a range of 10 to 20 mm. It can also be seen that, in the embodiment according to FIG. 19, the sections 64 , 84 which are inclined with respect to the respective directions again have a section 172 extending in the direction of the faceplate 40 , ie in the direction of displacement of the connecting rod section 44 , or a section extending in the longitudinal direction of the extension arm 38 extending section 174 connects. These sections have the result that when approaching the open position, a predetermined displacement stroke of the connecting rod portion 44 and thus the pivot axis S3 of the transmission plate 68 again leads to a smaller pivoting stroke, so that even in the final phase there is a favorable force transmission ratio, in particular when closing a Wing allows easier operation. When entering the section 172 , the transmission plate 68 is no longer pivoted by the guide projection 70 which is then guided in a straight line and parallel to the slot-like opening 56 . However, since the guide projection 76 , which engages in the slot-like opening 78 on the extension arm 38 , is not moved in a straight line towards the pivot axis S1, but instead is guided parallel to the displacement movement of the pivot axis S3 on the pivot axis S1, a pivoting movement of the extension arm 38 is nevertheless generated. It can thus be seen that, in order to cause a pivoting movement of the raising arm 38 , the guideway 78 would in principle not have to have an inclined section, since the guide projection 76 laterally offset with respect to a line passing through the pivot axes S3 and S1 inevitably leads to a pivoting of the raising arm 38 .

It should also be pointed out that the drive of the drive rod section 44, or of the entire drive rod system 26 , can also be effected by an electric motor or, for example, by the handle device 34 shown in FIG. 11 when used in conjunction with turn-tilt wings. A cardanic drive by a along the wing 14 or the outer area of the same Kardansy stem is possible, especially when positioning the wing to be operated in the upper and inaccessible area of a room.

With reference to FIGS. 2 to 11 and 12 to 19, respectively, opening devices for use with tilting sashes or rotary tilting sashes have been described, each of which comprises an opening arm. However, it may be advantageous, in particular in the case of heavier and wider wings, to provide a plurality of such extension arms across the width of the wings in order to obtain a better distribution of the forces which occur when tilting. Fig. 20 shows in their sections a), b) and c) a system in which the stay device 18 includes two pivoting arms 38 and 38 'comprises. As described above, each of these swivel arms 38 , 38 'can be actuated via a respective drive rod section 44 or 44 ' for the swivel movement. It can be seen in Fig. 20 that the two pivot arms 38 , 38 'are positioned in opposite directions to one another and thus, when changing from the closed position to the shown tilt-open position about their respective pivot axes 51 or S1' on the faceplate 40 or 40 'in the opposite direction of rotation swivel. This requires that the two drive rod sections 44 , 44 'must also be displaced in the opposite direction in order to generate the respective pivoting movement. For this purpose, between the two drive rod sections 44 , 44 ', as indicated by the dashed line in FIG. 20, a gearbox 180 is provided which can be brought into engagement with the drive rod section 44 ' with a toothed shoe 182 in linear displacement and with a toothed shoe 184 in linear displacement connection with the drive rod section 44 can be brought. In such a change gear 180 shown in a side section in FIG. 21, the toothed shoe 182 is, for example, coupled to a toothed rack part 188 , and the toothed shoe 184 is coupled to a toothed rack part 186 . A gear wheel 190 is positioned between the two rack parts 186 , which is rotatable in the change gear 180 , but is otherwise held stationary. If, for example, the toothed shoe 182 is shifted in a straight line, this movement is converted into an oppositely directed movement of the toothed shoe 184 by the toothed rack section 186 and the toothed wheel 190 and the toothed toothed section 188 .

For actuation or control of the two extension arms 38 , 38 ', however, it is then advantageous to direct the actuating force directly onto the gear 190 , that is to say, for example, as described above, to drive the latter through a square pin 192 of the gear 190 to rotate it , wherein this rotation is converted via the two rack sections 186 , 188 into oppositely directed displacement movements of the toothed shoes 182 , 184 . These opposite displacement movements lead to opposite displacement movements of the drive rod sections 44 'and 44 and to the corresponding pivoting of the deployment arms 38 ', 38 . It should be pointed out that, in such a configuration, the two extension arms 38 , 38 'with their associated components, which cause the same to pivot, are designed to be mirror-symmetrical.

It can be seen in Fig. 20 also, that the two pivot arms are held 38, 38 'about respective pivot axes S2, S2' on the non-illustrated frame pivotable. In order to be able to use such an arrangement even with a turn-tilt sash, it is necessary to be able to release the pivotable connection from one of the extension arms 38 , 38 'in the region of the pivot axis S2 or S2', in order then to rotate about the other axis S2 or S2 'to be able to perform the rotary-pivoting movement of the wing.

Figs. 22 to 24 show an arrangement with which the region of the pivot axis S2 ', such a release of the rotary joint can be produced. It can be seen in Fig. 22a) the end region of the opening arm 'which via the bearing sleeve 46' component on a frame-fixed bearing eyes can be pivoted 194 38th For this purpose, a bearing rod 196 is provided, which is shown in the illustration b) of FIG. 22 to the side next to the bearing eye component 194 in order to make the relative positioning more clearly recognizable. However, it should be noted that this bearing rod 196 engages the bearing eye component 194 and the bearing sleeve 46 'in order to establish the pivot connection. In its other end region, the bearing rod 196 , as can be seen in section b) of FIG. 23, is firmly connected to a sliding part 198 of a manual control unit 200 , for example by a clamping screw 202 . The sliding part 198 is movable in a sliding sleeve 204 fixed in the frame in the longitudinal direction of the bearing rod 196 . A hand lever 206 is pivotably mounted on the sliding sleeve 204 . This hand lever 206 has a gear segment-like configuration 208 , which meshes with a rack configuration 210 on the displacement part 198 . The section b) of FIG. 23 shows, in accordance with the section b) of FIG. 22, a positioning of the hand lever 206 or of the bearing rod 196 , in which the bearing rod 196 engages both in the bearing eye component 194 and in the bearing sleeve 46 'and thus creates the swivel connection around the axis S2 '. Starting from the representation of FIG. 23b) of the hand lever pivoted 206 in which in Fig. Position shown 23c), this leads to a shift of the shifting member 198 downward, with the close-coupled with the slider 198 bearing rod 196 follows this movement and thereby, as shown in Fig. 23c) emerging from the bearing sleeve 46 ', but in the Lageraugenkom component 194 remains. It is then in this state that the coupling of the bearing sleeve 46 'to the frame 12 is canceled, so that the wing 14 is released for rotary pivoting movement in this area. If a coupling is to take place again, starting from the positioning shown in FIG. 23c), the hand lever 206 is pivoted in the direction of the sliding part 198 , so that this is brought back into the positioning shown in FIG. 23b) and the bearing rod 196 in the positioning shown in Fig. 22b) pushes.

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

In order to enable the rotary movement about the vertical axis A2 shown in FIG. 1, the tilting bearing 24 must also be released. As already mentioned above, this can be done by components provided on the bearing 24 itself, but, as described below with reference to FIGS. 23 and 24, is preferably carried out simultaneously with the loosening of the connection in the region of the pivot axis S2 '.

It can be seen in FIG. 23 that a further bearing rod 209 is fixedly coupled to the sliding part 198 and extends with respect to the bearing rod 196 in the opposite direction. In its free end region, the bearing rod 209 passes through a further bearing eye component 211 , which can be seen in section a) of FIG. 24. Furthermore, in this free end region, the bearing rod 209 has a flattened section 212 , which, however, ends with a head 214 which is expanded again. When the coupling is produced, this extended head 214 lies in the area of the bearing 24 in a circular receiving area 216 of a tilting bearing component 218 fixed to the wing 14 , which can be seen in plan view in the lower part of section a) of FIG. 24. In the positioning of FIG. 24 in the section) b engages the enlarged head 214 in this circular region 216 and forms with the latter a kind of ball joint. However, if the hand lever 206 is moved into the positioning shown in section c) of FIG. 23, the flattened area 212 of the bearing rod 209 enters the circular area 216 of the bearing component 218 . The flattened area 212 is then aligned with a side opening 220 in the bearing component 218 . The wing can now be pivoted so that the flattened section 212 passes through the opening 220 . If the sash is closed again from the rotational opening position, the flattened area 212 re-enters the opening 220 and the circular area 216 , and, after the hand lever 206 has been moved into the position shown in FIG. 23 section b), occurs again the expanded, head-like area 214 into the circular area 216 and, together with this, restores the ball-joint-like connection in order to enable a tilting operation. It should be pointed out that instead of the hand lever 206 , an electric motor drive can also be provided here, in which a drive pinion meshes with the rack configuration 210 .

Further, it can be seen in Fig. 23, that the slide member 198 a locking screw can be provided 222, which is not possible in the position in which a rotary-opening operation, namely, the apparent position in Fig. 23b) with an opening 224 in the sliding sleeve 204 is aligned. By unscrewing the screw 222 , it can be moved into the opening 224 in order to block the entire arrangement against displacement and to ensure that an undesired loosening in the two bearing areas is prevented.

The FIGS. 25 to 27 show a configuration in which one of the two in Fig. Raising arms 20 illustrated, namely, the extension arm 38 ', the area of its pivot axis S2' are not located on an outer to the window frame 14 bearing pivotably, but in a bearing assembly 226 is mounted, which is fixed to the inner surface 30 ( FIG. 27) of the frame 12 . This situation is illustrated in Fig. 26. In order also to transition to a rotary operating a connection in the region of the pivot axis to be able to S2 'resolve, the device 226 against a bias of a spring 228 slidable displacement component 230th This sliding component 230 engages between the frame 12 and the wing flap 232 and has a manual operation part 234 , which can be moved along the outer edge of the wing flap 232 against the bias of the spring 228 . A glare-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 bearing pin 240 forming the axis S2 'and firmly connected to the deployment arm 38 ' can be pivotally received. When the movable part 230 in the illustration in FIG. 27 is displaced to the right, a passage opening is formed through which the bearing pin 240 can emerge, so that the pivot bearing connection is released in the region of the axis S2 '. If the sash is then moved out of the rotary open position again into the closed position, the bearing pin 240 abuts a diagonally illustrated inclined surface 242 of the displaceable part 230 , displaces this part 230 against the pretension of the spring 228 in the illustration in FIG. 27 to the right and enters the bearing opening 238 , whereupon the part 238 is moved again by the spring 228 into a position in which the bearing pin 240 is securely held in the bearing opening 238 .

A comparison of FIGS. 20 and 25 shows that when the extension arm 38 of FIG. 20 is combined with the extension arm 38 'of FIG. 25, the pivot axes S2 and S2' lie in different planes. The pivot axis S2 'of FIG. 25 is namely in a plane E1, which in the closed position approximately corresponds to the longitudinal central axis of the actuating arm 38 '. In contrast, the pivot axis S2 lies in a plane E2 (see FIG. 20), which is offset by an offset V in the direction of the arrow V with respect to the plane E1. However, since the two pivot axes S1 and S1 'lie in the same plane defined by the faceplate 40 , it is necessary, when performing a tilting movement, to provide different opening angles for the extension arms 38 and 38 ' in order to obtain a free movement in order to offset V compensate. This can be achieved, for example, in that, in the case of the extension arm 38 ', which, owing to the offset V, requires a larger swivel angle, one of the elongated holes 90 ', 92 'with respect to the longitudinal direction L of the extension arm 38 ' as shown by the line S in FIG. 25 is indicated, inclined, in order, as described above, to obtain a larger tilting stroke with the same pivoting out of the arm section 86 'with respect to the faceplate 40 '. Correspondingly, one of the slot-like openings could be inclined in the opposite direction in the raising arm 38 in order to produce a reduced tilting stroke here. In this way, a force-free tipping of the wing can be achieved without having to ensure that the two drive rod sections or transmission plates which drive the raising arms 38 or 38 'would have to be configured differently from one another. Nevertheless, it is also possible to move the two drive rod sections, which control the various extension arms, by means of a conversion gear so that they perform a different displacement stroke. It is also possible to provide different configurations of at least one of the extension arms in the region of the guide tracks for the guide projections of the transfer plate, in order to generate different pivoting movements of the two extension arms 38 and 38 'there, respectively.

Figs. 28 to 31 show an arrangement by which the 25 to 27 shown device 226 of a manual actuation device can be driven in Fig. Means. This Handbetäti supply device shown in FIGS . 29 and 30 corresponds in structure essentially to the hand-operated device already described above with reference to FIG. 23. It comprises a sliding sleeve 204 which can be fixed again on the frame, with a sliding part 198 which can be moved therein. The hand lever 206 again has a toothing configuration 208 , which meshes with a toothed rack configuration 210 on the sliding part 298 , so that by pivoting the hand lever 206 carried on the sliding sleeve 204 , the sliding part 298 can be pushed up and down in the longitudinal direction of the sliding sleeve 204 .

An actuating rod 250 is firmly coupled to the sliding part 198 , for example by a clamping screw or the like, which, as can be seen in particular in FIG. 28, extends upward into the area in which the bearing device 226 is provided. The slide rod 250 passes through a guide component 252 there and carries a slide wedge 254 at its free end. The part 234 of the device 226 that emerges between the wing flap 232 and the frame 12 also has a wedge surface 258 that is complementary to the wedge surface 256 of the sliding wedge 254 . When the hand lever 206 is pivoted clockwise from the position shown in FIG. 30 and the movement of the sliding part 198 and the sliding rod 250 induced thereby downward, the sliding wedge 254 presses through its wedge surface 256 onto the wedge surface 258 of the part 234 and moves it in the illustration of Fig. 28 to the right. As a result, the displaceable part 230 of the device 226 releases the bearing pin 240 in the region of the bearing opening 238 . The sash can then be swiveled during turning operation. If the hand lever 206 is pivoted back into the position shown in FIG. 30, the part 234 can return to the position shown in FIG. 28 and the bearing opening 238 is closed again. A subsequent closing of the wing leads to the fact that the bearing pin 240 shifts the inclined surface 242 of the displaceable part 230 against the bias of the spring 228 , so that it can re-enter the opening 238 Lageröff.

It should be noted that the returning of the hand lever 206 to the position shown in FIG. 30 can also be achieved by the pretensioning of the spring 228 , since this pretensions the part 234 to the left in FIG. 28, the pretensioning also resulting in the Shift wedge 254 and thus the shift rod 250 in an upward direction can be tensioned. It should also be pointed out here that a motor drive can again be provided instead of the hand lever.

The Figs. 32 to 34 show in conjunction a deployment device 18, in which again two raising arms 38 and 38 'are provided. It can be seen that here the two extension arms 38 , 38 'are constructed identically to one another or are pivoted in the same sense. It is thus possible to couple the two connecting rod sections 44 , 44 'directly to one another for common movement without having to provide a change gear between them. The drive can then over one of the driving rod sections 44 relation ship as 44 'can be made or by a rod sections with these two drive 44, 44' carried associated drive rod system. In such a configuration, one of the extension arms, namely the adjustment arm 38 ', is connected to the frame with a different type of bearing arrangement in the region of its pivot axis S2' than the other of the two extension arms. For this purpose, as can be seen in Fig. 33, the bearing device 226 is again provided, the structure and function of which correspond to those described above. A more detailed description is therefore no longer necessary. It should be noted that an opening 260 can be provided in the part 234 projecting beyond the wing flap, which serves to receive a Bowden cable 262 , so that remote control can be carried out again via a Bowden cable system.

Here, too, it is necessary to provide different tilting strokes with the same movement of the drive rod sections 44 and 44 ', since the two pivot axes S2 and S2' are again in the mutually offset planes E1 and E2. For this purpose, the arm 38 'in turn, the slot-like opening 90 ' is inclined with respect to the longitudinal direction L of the extension arm 38 , so that for the extension arm 38 'upon transition to the tilting position by the previously detailed kinking of this extension arm 38 ' by the offset V enlarged tilt stroke can be provided for the wing. Otherwise, the system shown in FIGS. 32 to 34 essentially corresponds to the functional principle described with reference to the preceding embodiments.

The present invention provides an opening device which by means of minor adaptation measures in a simple manner use with a tilt sash or a turn-tilt sash can be adjusted. When induced by the display device The pivoting movement of the various extension arms becomes one achieved that a relatively large movement force in the area of the closed position is present, while in the area of the tipping position a relatively large tipping stroke of a wing for a given displacement of a drive rod system is induced. These different states of motion with the Force transmission described above, especially in the vicinity of the The closed position can be caused by the inclination described above at least one of the guide openings of the telescopic connection of the extension arm can also be achieved in that it is inclined Guideway has a curved course, for example from one essentially in the longitudinal direction of the extension arm extending portion in a curved or with respect to this Longitudinal direction oblique section merges. On the other hand, she sees present invention the simple coupling of the display system to a Conventional greenhouse provided for window or door sashes system, because the normally existing drive rod stroke, which is 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 rotary position to the tilt position in The range of 18 mm can be sufficient for a sufficient tilt stroke to provide for the wing. Should that be the case with a greenhouse existing system stroke is not sufficient, for example way between this drive rod system and the drive rod section th of the present invention, a motion transmission gear be provided, which has a displacement stroke of the drive rod system  in an enlarged displacement stroke of the drive rod sections, which the Set the extension arms in motion.

Furthermore, the system according to the invention provides the option of Provide drive both manually and by electric motor, or if necessary, provide both drive options so that in the event that, for example, the electric motor drive still fails Manual operation is possible. It should be noted that in principle also for example, a pressure fluid actuated drive to generate the Ver pushing force can be used for the drive rod sections.

Embodiments have been described above at which the drive rod system is arranged on the wing. In particular when used in conjunction with tilting sashes, which have a rotating option is not provided, it can be advantageous, however, that in the figures illustrated drive rod section or faceplate section to provide on the frame and the pivot axis S2 in the area of Wing to relocate. The drive can then also be on the frame side take place so that it is not necessary when using an electric motor lead the drive lines in the area of the wing. Can too then the electric motor drive can be provided on the frame and does not have to be tilted together with the wing. This one too In one embodiment, it is then possible to close the drive rod system block provided, which with striking plates positioned on the wing or Closing latches help to lock the sash on the frame.

The accompanying drawings show that in the area of the various swivel or sliding connections, that is to say for example in the area of the telescopic connection 98 or in the area of the bearing connection of the bearing pin 240 , a possibility is created in each case that the components which are mounted on one another are not only a swiveling or guiding movement , but can also perform a twisting movement with respect to each other. This is particularly advantageous in the area of the raising arm 38 , which is intended both to perform a telescopic movement and also to be wounded in relation to one another by the tilting of the two pivot axes S1 and S2 that occurs with respect to one another. Such an additional tilting or twisting movement is made possible by the spherical design of the various bearing or guide bolts 94 , 96 or 240 . Furthermore, all of the bearing parts provided in the area of the pivot axes S2 can be hidden, ie they can be included in the rebate air or be hidden by the wing flap.
