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 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 pivoting movement of the opening 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 a display device from German publication 1 708 852 known for windows or doors, in which at Carrying out opening or closing operations of the transmission link and swivel the extension arm 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 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 displacement drive for others, for example on the wing To couple locking elements, 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 sash pivotally attached to a frame to provide 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 and tilt sash attached to a frame, in particular window casements or door casings, 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 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 device attached to the sash or frame the first and second pivot axes with respect to the wing or of the frame are essentially fixed and that at Swiveling the at least one extension arm from a closed position assigned to the wing 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 moved to a pivot axis from the first and second pivot axes the pivot axis of 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 pivoting only a relatively small pivoting path of the extension 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-out angle of a wing, which is a corresponding Force 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, so the transmission link 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 one 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 dispensing device according to the invention has less Overall width as a result of the closer to the pivot point of the extension 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 transmission link to a sliding movement of a conventional one 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 components defining these swivel axes 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 displacement movement of the conversion gear arrangement converting the drive unit.

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 guiding 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 the management component and transmission link, the guideway of the first guideway arrangement at least in some areas with respect to the direction of displacement of the drive unit runs obliquely.

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 second arm arrangement acting with the deployment arm 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 guideway arrangement at least in some areas 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 the guideway respectively carry the guide member 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 conventional Espagnolette 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 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 that assigned to the respective guideway Guide part with the extension arm in the first swivel position lies, one along the direction of displacement of the drive unit or the first portion extending in the longitudinal direction of the extension arm 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 the inclination of one of the guideways of the telescopic Connection of the two arm sections an additional contribution to Tilting stroke of the wing can be delivered, depending on the direction of inclination 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 opening device is generally provided by the 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 these respectively assigned transmission 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 the at least two extension arms a drive unit of the drive device 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 directions for 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 pivot 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 Extension arm lying in the other corner or coupled to the frame 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 to connect the frame-side couplings of the same in 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 stroke 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 extension 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 expedient embodiment 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 to the wing which can be coupled or a part of the drive rod 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 and tilt sash attached to a frame, in particular window or door sash, which comprises: at least one extension arm, which on the wing about a first pivot axis and attached to the frame pivotable about a second pivot axis or can be attached, 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 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 window, especially skylight, with a display device according to the invention or / and a turn-tilt door with an inventive Display device.

1 schematically shows a front view of a tilt and turn window 10, in which an opening device according to the invention is used can. The tilt-and-turn window 10 has a fixed frame 12 on, as well as one with respect to the frame 12 both rotating and tiltable sash or sash frame 14. On an upper horizontal bar 16 of the wing 14 is the opening device described in detail below 18 attached, the other in a rotary bearing 20 on Frame 12 is articulated. In the lower right corner, wing 14 is over a corner bearing 22 with respect to the frame 12 both around a horizontal Axis A1 can be tilted and pivoted about a vertical axis A2 stored. At the lower left corner, the wing 14 is via a detachable tilt bearing 24 attached to the frame 12 pivotable about the horizontal axis A1.

In a manner known per se, a dashed line is shown on the wing 14 Espagnolette system 26 is provided, which a plurality of Lock block 28 can move, depending on the movement position with not shown, provided on an inner surface 30 of the frame 12 Strike plates or latches can interact to to lock the wing 14 with respect to the frame 12. The drive rod system 26 has respective corner deflections in a manner known per se 32 and can be driven, for example, by a handle 34, which when pivoting in the direction of the arrows shown in Fig. 1 over a Gear rack and pinion mechanism 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 Rotational movement in a linear displacement movement of the drive rod system 26 can implement, thereby moving the locking block 28 and how described below, the tilting device 18 the wing or casement 14 to control.

FIG. 2 shows a top view of such an opening device 18. This comprises an extension arm, generally designated 38, which in one End region on a faceplate 40 can be pivoted about a pivot axis S1 is attached, the pivot axis S1 in the closed state of the Window represents a substantially vertical axis. This Face plate 40 is in a manner known per se on an outer peripheral surface 42 (Fig. 1) of the wing 14 attached and conceals this in one Wing rebate groove drive rod system 26, one of which is shown in FIG under the faceplate 40 drive rod section 44 dashed is indicated. The opening device 18 is then essentially in the Folded air between surfaces 42 and 30 of wing 14 respectively of the frame 12.

In its other end region, the extension arm 38 has a bearing sleeve 46 of the rotary bearing 20 recognizable in FIG. 20.

On the faceplate 40 there is also a guide plate which can also be seen in FIG. 8 48 set, the fixing of the guide plate 48 to the Extension arm 38 is used for pivoting bolts or rivets 50, and elsewhere a separate fastening bolt or rivet 52. It should be noted that for easier pivoting between the guide plate 48 and the extension arm 38 a slide 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 the pivot axis S1 and designated 56 substantially rectilinear in the longitudinal direction of the faceplate 40, d. H. in Extends circumferentially, and the other, designated 58 from the Swivel axis S1 is further away. The slot-like opening 58 has a first substantially straight in the circumferential direction Section 60, a curved transition area 62 and a second portion 64 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 connecting rod section 44, and the on the other hand, a transfer plate 68 by one over the guide plate 48 fixed with respect to the drive rod portion 44, but with this in the circumferential direction linearly displaceable axis S3 carries. In its pivotable attachment to the drive rod section 44 distal end portion, the transfer plate 68 has one in the form of a Bolts or rivets trained guide projection 70, which itself extends downward into the transfer plate 68 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 68.

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, i.e. H. extends upwards and into an elongated hole-like opening 78 in a widened area 80 of the Extension arm 38 engages. The slot-like opening 78 in the opening arm 38 has two sections, namely one from the pivot axis S1 further away and to the longitudinal direction L of the extension arm 38 substantially parallel first section 82 and a pivot axis following a transition region 83 S1 closer and inclined with respect to the longitudinal direction L. second section 84.

It can also be seen in FIGS. 2 and 3 that the extension arm 38 consists of two Arm sections 86, 88 is constructed. The arm section 86 is on the Cuff rail 40 pivotally attached, and the arm portion 88 carries the Bearing sleeve 46 and is pivotable on the panel frame 12 about the axis S2 attached or attachable. One of the arm sections, namely the arm section 88 has two slot-like openings 90, 92 in which on the arm portion 86 guide pin 94, 96 in are essentially feasible in the longitudinal direction L of the extension arms 38. It is in the way in the transition area between the two Arm sections 86, 88 created a telescopic connection 98, which compensates for length when performing a tilting movement of both the frame 12 and the wing 14 to with respect to this in each case essentially fixed axes S2 or S1 allow hinged extension arm 38. It should be noted that on Assembling the two arm sections 86, 88 the slot-like Openings 90, 92 each have enlarged end regions 100, 102, through which heads the guide bolts 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 normal operation of a window does not open to avoid the two Arm sections 86, 88 are unwanted detached from each other.

The actuation of the opening device 18 is used, as already mentioned above addressed, a gear rack arrangement, which in Fig. 3rd is recognizable. This includes several on the drive rod section 44 Cutouts 108, which together with the cutouts 108 separating webs 110 form a rack-like formation. Further is A wheel 114 provided with external teeth is rotatable in a carrier 112 stored, which has an inner square opening 116. In these Inner square opening 116 can be, for example, a square rod below to be described handle used to Wheel 114 for rotation and thus the drive rod section 44 for To drive displacement, or it can for example on the square bar a worm or gear can be arranged, which with a Worm or gear wheel of a rotating shaft of the electromotive drive 36 of Fig. 1 combs so that the drive can be done by an electric motor. In particular in the case of an electric motor drive, it can also be provided that assign a conversion gear to this drive, which has a rotary movement of the rotor into a linear displacement movement, for example also via a worm gear, where then, for example Espagnolette section 44 two projections spaced apart from one another can form a receiving opening into which a driver of the linear displaceable component of the transmission engages around the drive rod section 44 to move.

The following is the function of the display device according to the invention described in particular with reference to FIGS. 7, 9 and 10. Be there 10, which is a position of the extension arm 38 or the section 86 recognizable there reproduces the same, which corresponds to a closed position Z of the wing 14. That is, 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 shifted to the right to the maximum extent is, so that the two guide projections 70 and 76 each in End region of the section extending in the longitudinal direction of the faceplate 60 or 82 of the respective elongated openings or Guideways 58, 78 lie. In this position the display device sees 18 even a lock, since also by exercising one Tipping force on the wing 14, for example due to wind Guide projections 70, 76 not shifted in sections 60, 82 can be. It can also be seen that the sections 60, 82 of the slot-like openings 58, 78 laterally spaced and each close to a lateral end region of the guide plate 48 or of the widened section 80 of the extension arm 38 are positioned. To The openings extend in their respective curvature regions 62, 83 58, 78 then diagonally to the faceplate longitudinal direction to the other lateral end region of the guide plate 48 or the widened Section 80 of the extension arm 38. In this way becomes, as can be seen below, with minimal lateral Overall width achieved the greatest possible pivoting efficiency. However, it is pointed out that the two slot-like openings 58, 68 others can have lateral positions to each other. Most of all, this is possible because they are not provided in the transfer plate 68, but in different components.

Is now based on the positioning shown in Fig. 10 by the drive, d. H. either a handle 34 or an electric motor Drive 36, the drive rod section 44 moved to the left, so moves until the curvature sections 82, 83 are reached Extension arm 38 does not initially relate to the faceplate 40. With this However, the closing block 28 of the drive rod system, which is coupled to the drive rod section 44, from their respective striking plates or latches. As long as However, the locking block still interacts with the locking mechanism assigned locking latches, may and may pivot or Tilting of the wing 14 does not occur. After reaching the sections of curvature 62, 83, however, the locking block 18 is no longer in locking engagement with the assigned locking latches, and after passing this in 9 recognizable positioning of the guide projections 70, 76 can Start pivoting movement of the extension arm 38.

The guide projection 70 now moves in the oblique direction Section 64 of the opening 58 into it, as can be seen in FIG. 7, so leads to the continued displacement of the drive rod section 44 and the associated displacement of the pivot axis S3 Transfer plate 68 in the direction of the pivot axis S1 of the extension arm 38 to a pivoting movement of the transfer plate 68 with respect to the faceplate 40 and thus the wing 14. This pivoting movement the transfer plate 68 about the axis S3 is by the Guide projection 76 also transferred to the extension arm 38. However, since the guide protrusion 76 in the obliquely extending portion 84 the opening 78 runs, a pivoting movement of the Extension arm 38 with respect to the transfer plate 68, but in the same Swing direction forced. Ultimately, it forms the transfer plate 68 with its two guide projections 70, 76 a wedge that at Approximation of the pivot axis S3 to the pivot axis S1 between the both surfaces or wedge surfaces formed by openings 58 and 78 74, 118 is pushed in and thereby the extension arm 38 of the Forend rail 40 swings away. Since the two guide projections 70, 76 extend in different directions, but need not necessarily 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. A movement of the two guide projections 70, 76 also leads there in the direction of the arrow that the guide projection 70 along the through the Opening 58 formed guideway is moved up and that due to the leading projection that also moves upwards 76 also the guideway 78 is shifted up, what is further reinforced by the fact that the guide projection 76 extends along of the inclined portion of the guide track 78 moves.

This principle of operation has several advantages. On the one hand one recognizes that through the two inclined web sections one induced by linear displacement of the drive rod section 44 Sliding movement of the swivel axis S3 and thus the transfer plate 68 into an even larger pivoting movement of the opening arm 38 implemented about the pivot axis S1 and thus also the pivot axis S3 becomes. This is particularly important if the invention Display device 18 in conjunction with a normal Espagnolette system is to be used. With such drive rod systems is the displacement stroke of the respective drive rod sections in essentially specified, with a first part of the displacement stroke, such as mentioned above, for releasing the locking engagement of the locking block with the associated locking latch is required, and only the second part of the displacement stroke can be used for a pivoting movement of the extension arm. That is, this relative small displacement stroke must be in the largest possible swing stroke and thus tilting stroke of the wing 14 can be implemented. Another advantage of Display device according to the invention is that by the wedge-like acting Transmission plate 68, which with increasing pivoting of the Extension arm 38 of the pivot axis S1 of the same, starting from the closed position, the points of attack on the extension arm 38 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, a 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, the pivot axis S3 approaches the pivot axis S1 in the course of the displacement movement of the drive rod section 44, so there are also points of interaction, defined by the leadership tabs 70, 72 closer to the pivot axis S1. A shift stroke by the same amount therefore necessarily leads to a much larger one Pivotal movement of the arm 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 area of Closed position at the beginning of an opening movement or at the end relatively large forces can be provided for a closing movement, to existing on the frame 12 or on the wing 14, for example To be able to deform seals.

It should be noted that the above with reference to FIGS. 2 to 10 system described in particular for use with tilting wings is suitable, such as. B. skylights provided in larger halls. There here a pivot position is not required, the tilt bearing 24 (Fig. 1) be a permanently coupled warehouse, and in the design of the The rectilinear section can have respective slot-like openings 58, 78 60 or 82 can be made relatively short, with the advantage that that the inclination of the inclined Sections 64 and 84 with respect to the direction of displacement of the Espagnolette section 44 (at section 64) respectively with respect to the longitudinal direction L of the extension arm 38 (at the section 84) can be kept small. This in turn leads to moving the wing has more favorable force ratios.

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 extension arm 38 could be inclined. The inclination of this guideway 98 would result in that in the forcibly occurring during the tipping process Telescopic movement of the two arm sections 86, 88 with respect to one another these are forced into an inclined position with respect to one another, which is illustrated schematically in Fig. 2a. Since the arm section 86 through the transfer 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 is held, the additional tilting of two arm sections 86, 88 that forcibly opposite one in 2a dashed line configuration of the Ausstellarms 38 an additional tilt path W can be obtained. Alone this measure can therefore be independent of the one described above Functionality in the area of the transfer plate can be used a predetermined displacement stroke of a drive rod section into one increased swivel stroke of the extension arm or the tilting arm To implement the wing.

It should also be noted that the extension arm 38 is also more than that can have two arm sections shown, for example three May have arm sections, of which two each with each other in the previously described telescopically connected together could be. Even with such a configuration with several Arm sections can then at least in the area of one of the telescopic Connections can be provided to the inclination of a guideway to get the above-mentioned effect.

Fig. 11 shows a handle device 34 which is used to control the system described above can be used. It's the Square bar 122 recognizable, which with the previously described toothed wheel 114 connectable for common rotation is. The square rod 122 is by a bearing arrangement 124 on a Wing 14 attachable support unit 126 rotatably mounted. He takes action also a square opening 128 in the handle part 130 and carries on his End a cap 132 serving as a push button. Is supported on this cap 132 a spring 134 engages, which at the other end presses on the handle part 130 and to bias this towards the carrier unit 126, because of the Bearing arrangement 124 of the square bar 122 with respect to the carrier unit 126 is rotatable, but is not displaceable in its longitudinal direction. Around the rotatable mounting of the square bar 122 has the Carrier unit 126 several z. B. conical recesses 136 on the preferably with a uniform mutual distance in the circumferential direction are arranged around the square bar 122. On the handle part 130 is preferably a corresponding number of z. B. conical Projections 138 are provided which are the same relative distance as have the recesses 136. By the spring 134 are the projections 138 biased towards the recesses 136, see above that with a suitable relative rotational positioning between the handle part 130 and the carrier unit 126, the projections 138 into the recesses 136 intervene and thus provide a rotation lock for the handle part 130.

If the handle part 130 is to be moved, it can be gripped the same with the fingers of one hand and supporting the thumb on 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 emerge from the recesses 136. The handle part 130 can then to actuate the opening device 18 described above be pivoted and after reaching a desired tilt position one Wing can be released again, so that the projections 138 in again engage the recess 136 and through the locking thus formed hold a wing in a predetermined tilt position. Because of the conical Design of the recess 136 or the projections 138 can also be done exclusively by rotation, whereby then first by sliding the respective conical surfaces against each other Spring 134 is compressed and then when turning the handle member 130 after reaching the next relative alignment of the projections 138 with the Recesses 136 are locked again. It should be noted that a reverse situation is also possible, d. H. the ledges could be provided on the carrier unit 126. Nor is it required to provide as many projections 138 as there are recesses 136 are provided. You just have to make sure that the Number of recesses at least equal to the number of protrusions is. To obtain the most stable anti-rotation lock, the However, numbers should be the same size. It should be noted that in particular the retention when using an electric motor drive any intermediate position can also be achieved in that the conversion of a rotary movement of an engine component into a Sliding movement of the drive rod section 44 by a self-locking Relocation gear takes place.

12 to 19 show a modification of the invention Display device, which is particularly suitable for use with turn-tilt sashes suitable is. The basic structure corresponds to the previous one Structure described in detail, so no further explanation here is given. However, refer to Figs. 15 through 17 thereon noted that when used with a turn-tilt wing the respective rectilinear opening sections 60, 82 of the slot-like Openings 58, 78 may be extended with respect to the use in tilting sashes must, with the result that the inclined sections accordingly 64, 84, which between the rotary position D and the tilt position K lying, are shorter and therefore a larger one to maintain the same tilting stroke Have inclination with respect to the respective straight section have to. This configuration is due to the fact that when the position Z, which corresponds to the closed position, to the rotary position D, a larger stroke is required to lock the latch into one position bring that allows the wing to rotate about the vertical axis A2. Otherwise, this embodiment also has the two openings 58, 78 the rectilinear section required to initially do that Release the locking block without tilting movement already induced enable, and then after passing through the rotary position by the the above-described effect of raising the raising arm 38 by means of the sloping sections. It was in this Context still noted that to maintain the pivoting movement it is particularly advantageous that, for example, at slot-like opening 58 a lateral offset between the pivot axis S2 and that surface area of the guideway is created, on which the guide projection 70 is supported. The same applies for the lead tab 76.

For use with a tilt and turn sash, it is necessary to ensure that that the rotating telescopic connection 98 between the two Arm sections 86, 88 is not effective. It would be because of this telescopic connection a lack of fixation of the wing in the upper Area with respect to the frame 12 available. For this purpose a bridging arrangement 140 is provided, which on the faceplate 40 fixed includes a lock pin 142, and on the arm portion 88, which can be pivoted on the frame 12 about the axis S2 is attached, includes a bridging shoe 144. Is the extension arm 38 positioned in the closed position shown for example in FIG. 17, in which the arm section 88 lies over the faceplate 40, is the Bridging bolt 142 received in the shoe 144 and through the two sections lying in the longitudinal direction of the arm section 88 146, 148 of the bridging shoe 144 is a relative movement the faceplate 40 with respect to the arm portion 88 in the faceplate longitudinal direction and thus not in the longitudinal direction L of the extension arm 38 possible. It can then the wing 14 bypassing the telescopic Connection 98 are moved in the direction of rotation. However, this is it still required, the tilt bearing 24 shown in Fig. 1 bottom left to solve. This can be done, for example, by manually entering an on Tilt bearing 24 existing release lever is operated to a bearing pin to move out of a bearing eye. Should go back on Tilting operation must be carried out by turning the lever again be moved back into the bearing eye to again in this area a defined mounting of the wing 14 with respect to the frame 12 to provide. The bridging bolt then occurs at the transition to the tipping position 142 out of the bridging shoe 144 so that the arm portion 88 and the faceplate 40 with respect to each other can be moved.

It can also be seen in FIGS. 12, 13 and 14 that an additional Locking arrangement 150 in the area of the pivot bearing 20 (FIG. 1) can be provided. This locking arrangement 150 comprises for example an extension section 152 for the drive rod section 44, which with a toothed shoe 154 in a manner known per se in sliding coupling with a toothing section 156 on the drive rod section 44 can be brought. The locking arrangement further comprises 150 a faceplate section 158, which on Wing can be set. This faceplate section 158 passes through a bearing pin 160, which another Lock block 162 carries. The arm section 88 is for the locking block 162 a locking latch 164 is provided which, when the drive rod section is displaced 152 in the longitudinal direction in an opening area 166 den Locking block 162 can accommodate and then in the lateral direction secures against movement with respect to arm portion 88. The one for recording the locking latch 162 serving locking latch 164 is via a rivet 168 is pivotally mounted on the arm section 88 and has an eccentric arrangement 170 to by appropriate positioning of the latch 164 with respect to the arm section 88, the wing when the locking block enters 162 in the opening 166 forced to 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 areas 62, 83 have a significantly larger radius of curvature formed guideways is provided so that the transition from the rectilinear to the inclined sections is gentler and thus an easier operation is possible. The radius of curvature these transition areas 62, 83 should in any case in one area lie that is greater than the radius of curvature of the guide projections 70, 76, and is preferably in a range of 10 to 20 mm. Man also recognizes that in the embodiment according to FIG Portions 64, 84 inclined with respect to the respective directions again in the direction of the faceplate 40, d. H. in the direction of displacement of the connecting rod section 44 extending section 172 or one extending in the longitudinal direction of the extension arm 38 Section 174 joins. The result of these sections is that at Approaching the open position a predetermined displacement stroke of the Drive rod section 44 and thus the pivot axis S3 of the transmission plate 68 again leads to a smaller pivoting stroke, so that there is also a favorable power transmission ratio in the final phase, this is easier to operate, especially when closing a wing enables. When entering section 172, the straight and parallel to the slot-like opening 56 guided guide projection 70 the transmission plate 68 no longer pivots. However, since the guide projection 76, which in the slot-like opening 78 at Extension arm 38 engages, not in a straight line towards the pivot axis S1 is moved, but parallel to the displacement movement of the swivel axis S3 is guided past the swivel axis S1, nevertheless becomes a Pivotal movement of the arm 38 generated. So you can see that fundamentally to cause a pivoting movement of the raising arm 38 the guideway 78 does not have an inclined section would have to, because of one by the swivel axes S3 and S1 passing line laterally offset guide projection 76 forcibly leads to a pivoting of the extension arm 38.

It should also be noted that even when used in conjunction with Turn-tilt wings the drive of the drive rod section 44 or of the entire drive rod system 26 by electric motor 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 or the outer area of the same guided cardan system is possible, especially when positioning the one to be operated Wing in the upper area of a Space.

With reference to FIGS. 2 to 11 and 12 to 19 display devices for use with tilting sashes or Tilt-and-turn sashes have been described, each with an extension arm include. However, it can be especially heavy and ready Wings would be advantageous, several such across the width of the wings Extension arms to provide a better distribution of the tilting to obtain occurring forces. 20 shows in its sections a), b) and c) a system in which the opening device 18 two Includes arms 38 and 38 '. Each of these swivel arms 38, 38 'is as described above, over a respective drive rod section 44 or 44 'can be controlled 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 to the shown tilt-open position about their respective pivot axes S1 or S1 'on the faceplate 40 or 40' in swivel opposite direction of rotation. This requires that the two drive rod sections 44, 44 'to produce the respective Swivel movement can be shifted in the opposite direction have to. For this purpose is between the two drive rod sections 44, 44 ', as indicated by the broken line in FIG. 20, a change gear 180 provided that with a toothed shoe 182 in linear displacement engagement can be brought with the drive rod section 44 'and with a toothed shoe 184 in linear displacement connection with the drive rod section 44 can be brought. In such in Fig. 21 in Change gear 180 shown in side section is, for example Toothed shoe 182 coupled to a rack portion 188, and the Toothed shoe 184 is coupled to a rack part 186. Between two rack parts 186, a gear wheel 190 is positioned, which in Change gear 180 is rotatable, but is otherwise held stationary. Becomes For example, the toothed shoe 182 is shifted in a straight line, so the Rack section 186 and gear 190 and the rack section 188 this movement in an opposite direction of the tooth shoe 184 implemented.

To actuate or control the two extension arms 38, 38 ', it is then advantageous, however, to apply the actuating force directly to the To direct gear 190, i. H. for example as described above, through a into a square opening 192 of the gear 190 used square pin to drive this for rotation, this Rotation over the two rack sections 186, 188 in opposite directions directional displacement movements of the toothed shoes 182, 184 implemented becomes. These opposing displacement movements lead to opposing ones Sliding movements of the drive rod sections 44 'and 44 and corresponding pivoting of the raising arms 38 ', 38. Let it be said noted that with such a configuration, the two extension arms 38, 38 'with their associated components, which are the pivoting cause the same, are designed mirror-symmetrical.

20 that the two swivel arms 38, 38 'around respective pivot axes S2, S2 'on the frame, not shown are pivoted. To such an arrangement with one To be able to use turn-tilt sashes, it is necessary to use the swiveling Connection of one of the extension arms 38, 38 'in the region of the swivel axis To be able to solve S2 or S2 'and then around the other Axis S2 or S2 'is the rotary pivoting movement of the wing to be able to perform.

22 to 24 show an arrangement with which in the area of Swivel axis S2 'such a loosening of the rotary connection can be generated can. The end region of the raising arm 38 'can be seen in FIG. 22a), which via the bearing sleeve 46 'on a frame-fixed bearing eye component 194 can be pivotally attached. For this purpose a bearing rod 196 is provided, which is shown in the representation b) of FIG. 22 is shown laterally next to the bearing eye component 194 to the To show relative positioning more clearly. However, it was on it indicated that this bearing rod 196 in the bearing eye component 194th and the bearing sleeve 46 'engages to make the pivot connection. In its other end area is the bearing rod 196, as in that Section b) of FIG. 23 can be seen, with a sliding part 198 one Manual control unit 200, for example by a clamping screw 202, firmly connected. The sliding part 198 is fixed in a frame Sliding sleeve 204 movable in the longitudinal direction of the bearing rod 196. On the sliding sleeve 204 is pivotally mounted on a hand lever 206. This Hand lever 206 has a gear segment-like configuration 208, which with a rack configuration 210 on the sliding part 198 combs. 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 both in the bearing eye component 194 and also engages in the bearing sleeve 46 'and thus creates the swivel connection around the axis S2 '. Is going out from the illustration in FIG. 23b) of the hand lever 206 in the in FIG. 23c) position shown pivoted, this leads to a shift of the Sliding part 198 down, the one with the sliding part 198 fixed coupled bearing rod 196 follows this movement and, as in FIG. 23 c) shown, emerges from the bearing sleeve 46 ', but in the bearing eye component 194 remains. In this state it is then the coupling of the Bearing sleeve 46 'lifted on the frame 12, so that in this Area of the wing 14 is released for rotary pivoting movement. Should there is a coupling again, starting from the in Fig. 23c) illustrated positioning of the hand lever 206 in the direction of the Sliding part 198 too pivoted so that this again in the in Fig. 23b) Positioning shown is brought and the bearing rod 196 in the in Fig. 22b) shown positioning pushes.

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

To enable the rotary movement around the one shown in FIG. 1 vertical axis A2, the tilt bearing 24 must also be released. This can, as already mentioned above, by the bearing 24 itself provided components take place, however, as follows with 23 and 24 described, preferably simultaneously with loosening the connection in the region of the pivot axis S2 '.

It can be seen in Fig. 23 that with the sliding part 198 another Bearing rod 209 is firmly coupled, which is in relation to the bearing rod 196 extends in the opposite direction. In its free end area the bearing rod 209 penetrates a further bearing eye component 211, which can be seen in section a) of FIG. 24. Furthermore, this shows free End region of the bearing rod 209 on a flattened section 212, the but ends with a head 214 expanded again. That expanded head 214 is in the coupling 24 in the area of the bearing 24 in one circular receiving area 216 fixed to the wing 14 Tilting bearing component 218, which is in the lower part of section a) of FIG. 24 is recognizable in plan view. In the positioning according to FIG. 24 in Section b) the expanded head 214 engages in this circular area 216 and forms a kind of ball joint with it. However, if the Hand lever 206 in the position shown in section c) of FIG. 23 moved, the flattened area 212 of the bearing rod 209 enters the circular region 216 of the bearing component 218. The flattened one Area 212 is then with a side opening 220 in the bearing component 218 aligned. The wing can now be pivoted so that the flattened portion 212 through the opening 220 passes through. If the sash is turned again from the turn-open position closed, the flattened area 212 again enters the opening 220 and the circular region 216, and after moving the hand lever 206 in the positioning shown in FIG. 23 section b), the step occurs again expanded head-like area 214 into circular area 216 and restores the ball joint-like connection with this, to enable tipping. 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 combs.

23 that a locking screw is located on the sliding part 198 222 can be provided, which in that position in which a rotary opening operation is not possible, namely that in Fig. 23b) recognizable position, with an opening 224 in the sliding sleeve 204 is aligned. By unscrewing the screw 222, it can be screwed into the Opening 224 can be moved in to complete the assembly to block against displacement and ensure that an unwanted Loosening in the two storage areas is prevented.

25 to 27 show a configuration in which one of the two Extension arms shown in Fig. 20, namely the extension arm 38 ', in Area of its pivot axis S2 'not on an outside of the frame 14 lying bearing is pivotable, but in a bearing device 226 is mounted, which on the inner surface 30 (FIG. 27) of the frame 12th is set. This situation is illustrated in Fig. 26. In order here too Transition to a turning operation a connection in the area of the swivel axis To be able to solve S2 ', the device 226 has a counter Biasing of a spring 228 sliding component 230 on. This displacement component 230 engages between the frame 12 and the wing flap 232 and has a manual operating part 234 on that along the outer edge of the wing flap 232 against the bias of the spring 228 can be shifted. A frame fixed Part 236 of device 226 and slidable part 230 together form a bearing opening 238 of the device 226, in which an axis which forms the axis S2 'and is firmly connected to the extension arm 38' Bearing pin 240 can be pivotally received. In the event of a shift of the movable member 230 to the right in the illustration of FIG. 27 a passage opening is formed through which the bearing pin 240 can emerge, so that the pivot bearing connection in the area of the axis S2 ' is solved. Will then from the rotary open position If the sash moves back into the closed position, the bearing pin 240 hits on a schematically illustrated sloping surface 242 of the displaceable Part 230 on, this part 230 moves against the bias of the spring 228 to the right in the illustration in FIG. 27 and enters the bearing opening 238, whereupon the part 238 is returned to a position by the spring 228 is moved, in which the bearing pin 240 securely in the bearing opening 238 is held.

A comparison of FIGS. 20 and 25 shows that when the Extension arm 38 of FIG. 20 with the extension arm 38 'of FIG. 25 Swivel axes S2 and S2 'are in different planes. 25 lies in a plane E1 which is in the closed position approximately with the longitudinal central axis of the extension arm 38 'matches. In contrast, the pivot axis S2 lies in a plane E2 (see FIG. 20) which is one by one with respect to plane E1 Offset V is offset in the direction of arrow V. However, since the two Swivel axes S1 and S1 'in the same, through which Face plate 40 defined level, it is when performing a Tilting movement required to maintain a free movement the opening arms 38 and 38 'different opening angles to compensate for the offset V. For example can be achieved in that with the extension arm 38 ', which causes requires a larger swivel angle due to the offset V, one of the slot-like openings 90 ', 92' with respect to the longitudinal direction L of Extension arm 38 ', as indicated by the line S in Fig. 25, inclined is, as described above, with the same pivoting of the Arm section 86 'with respect to the faceplate 40' a larger tilt stroke to get. Correspondingly, one of the oblong openings in the opposite sense are inclined to to generate a reduced tilt stroke here. That way a constraint-free tipping of the wing can be achieved without it to ensure that the two extend arms 38 and 38 ' driving drive rod sections or transmission plates to each other would have to be configured differently. Nevertheless, it is also possible by a conversion gear, the two drive rod sections, which the control different extension arms so that they move one execute different displacement stroke. It is also possible in the area of the guideways for the guide projections of the transfer plate from different configurations of at least one of the extension arms To provide there already different pivoting movements of the to produce two raising arms 38 and 38 '.

28 to 31 show an arrangement by which the in Fig. 25 to Device 226 shown in FIG. 27 by means of a manual actuation device can be controlled. This manual operating device shown in FIGS. 29 and 30 Its structure corresponds essentially to that already previously described with reference to FIG. 23 manual operating device. It comprises a sliding sleeve which can be fixed again on the frame 204, with a sliding part 198 displaceable therein Hand lever 206 again has a toothing configuration 208, which with a rack configuration 210 on the sliding part 298 Combing so that by pivoting the on the sliding sleeve 204th worn hand lever 206, the sliding part 298 in the longitudinal direction of the Sliding sleeve 204 can be pushed up and down.

With the sliding part 198 is an actuating rod 250, for example fixedly coupled by a clamping screw or the like, which, as can be seen particularly in FIG. 28, upwards into that area extends in which the bearing device 226 is provided. The Shift rod 250 passes through a guide component 252 and carries a sliding wedge 254 at its free end the wing flap 232 and the frame 12 emerging part 234 of the device 226 points to the wedge surface 256 of the sliding wedge 254 complementary wedge surface 258. When swiveling the hand lever 206 from the clockwise position shown in FIG. 30 and thereby induced movement of the slide member 198 and the slide bar The sliding wedge 254 presses 250 downward through its wedge surface 256 on the wedge surface 258 of the part 234 and thereby moves this in the 28 to the right. This gives the sliding part 230 of the device 226 the bearing pin 240 in the area of the bearing opening 238 free. The sash can then be swiveled during turning operation. Becomes the hand lever 206 is pivoted back into the position shown in FIG. 30, the part 234 can again be as shown in FIG Return position and the bearing opening 238 is closed again. Subsequent closing of the wing leads to the hinge pin 240 the inclined surface 242 of the displaceable part 230 against the Bias of the spring 228 moves so that it is back in the bearing opening 238 can occur.

It should be noted that the return of the hand lever 206 in the 30 shown by the bias of the spring 228th can be achieved since this part 234 to the left in FIG. 28 preloaded, the displacement wedge 254 due to this preload and thus the slide rod 250 is biased in an upward direction become. It should also be pointed out here that instead of Hand lever again a motor drive can be provided.

FIGS. 32 to 34 together show an opening device 18, in which in turn two extension arms 38 and 38 ' are provided. It can be seen that here the two extension arms 38, 38 ' are constructed in the same way or in the same sense be pivoted. It is thus possible to use the two drive rod sections 44, 44 'directly to move together couple without having to provide a change gear between them. The drive can then via one of the drive rod sections 44 or 44 'or can be done by one of these two drive rod sections 44, 44 'connected drive rod system. At Such a configuration is one of the extension arms, namely the extension arm 38 ', with a different type of bearing arrangement in the area of its Swivel axis S2 'tied to the frame than the other one two extension arms. For this purpose, as can be seen in Fig. 33, again the bearing device 226 is provided, its structure and mode of operation each correspond to that described above. A more precise one Description is therefore no longer required. It should be noted that in the part 234 projecting beyond the wing flap Opening 260 can be provided, which for receiving a Bowden cable core 262 serves, so that again via a Bowden cable system Remote operation can take place.

Again, it is necessary to have different tilting strokes for the same Provide movement of the drive rod sections 44 and 44 ', since the two swivel axes S2 and S2 'are again in mutual relation offset levels E1 and E2. For this purpose is the arm 38 'in turn the slot-like opening 90' with respect to the Longitudinal direction L of the extension arm 38 inclined so that for the extension arm 38 'at the transition to the tilt position by the previous one detailed bending of this arm 38 'by the offset V enlarged tilt stroke for the wing can be provided. Otherwise corresponds essentially to the system shown in FIGS. 32 to 34 those described with reference to the preceding embodiments Operating principle.

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. In the induced by the dispensing 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 drive rod system for window or door sashes before, because the normally existing connecting rod stroke, which in 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 drive rod system existing displacement stroke is not sufficient, for example between this drive rod system and the drive rod sections 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-operated drive to generate the displacement 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 electromotive Drive cables 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 have locking blocks on the drive rod system to be provided, which with striking plates or Closing latches help to lock the sash on the frame.

The accompanying drawings show that in the area of various swivel or slide connections, d. H. for example in the area of the telescopic connection 98 or in the area of the Bearing connection of the bearing pin 240 each created a possibility is that the components mounted together are not just a swivel or Leadership movement, but also a twisting movement can perform on each other. This is particularly true in the area of the arm 38 advantageous, which is both a telescopic movement should perform, as well as by the tilting occurring when tipping of the two pivot axes S1 and S2 are twisted in relation to each other must become. Due to the spherical design of the different Bearing or guide pin 94, 96 or 240 becomes one enables such additional tilting or twisting movement. Further can all bearing parts provided in the area of the swivel axes S2 lying face down, d. H. can be included in the rebate air respectively be covered by the flap.
