EP0703339A1 - Pivoting or pivoting and tilting window or door - Google Patents

Abstract

The tilt and turn gear allows the window, or door, to open as normal or to tilt into a ventilation position. The amount of tilt is controlled by a control arm (20) hinged between the window and the support frame. A joint (39,34,35,38) is positioned at the shaped (36) end of the control arm to recess into a compact setting in the support frame when the window is closed. The joint is linked to a hinge bracket (25) hinged about a vertical axis (24) on a support bracket (23) at the side of the frame. The joint and hinge are shaped to swing the window away from the frame during opening.

Description

The invention relates to a pivoting or tilting window or a door, in which or in which the wing is held at the top by a fixed on the fixed frame in a bearing block about a vertical axis pivoting device, which is covered with at least one between the fold peripheral surfaces of Wing and fixed frame located and acting on a wing-side holding and guiding rail either limit the tilt opening movement of the wing or when it rotates in parallel to this pivots. This involves in particular those turn-and-tilt windows or doors in which the sash and frame have an upper leg that is inclined in their plane with respect to the horizontal and the opening device near the frame-side bearing block on the opening arm is provided with a joint, the The axis extends both transversely to the axis of the bearing block and transversely to the longitudinal direction of the extension arm, around which the extension arm or arms extends relative to the bearing block or to its perpendicular hinge axis in accordance with the inclined position the upper wing leg and / or frame leg is adjustable.

Windows or doors of this type have long been known, as can be seen, for example, from DE 80 03 074 U1 and DE 81 03 368 U1.

When installing the known known with a transverse joint on the boom arm, the disadvantage arises in practice that despite exact adherence to the specified stop dimensions on the one hand for the bearing block on the fixed frame and on the other hand for the holding arm and guide rail connecting the extension arm to the wing undesirable fluctuations of so-called rebate clearance between the vertical rebate circumferential surfaces of sash and fixed frame. So between the hinge-side vertical fold circumferential surfaces of the sash and the fixed frame, the smaller the air gap, the more acute the angle of inclination of the extension arm around the transverse joint relative to its normal horizontal position in the downward direction, that is, it must be set up negatively. On the other hand, there is a corresponding effect if it is necessary to move the extension arm around the transverse joint from its normal horizontal position to an upward, ie positive, inclination position.

These system-related and possibly malfunctions in the opening and closing of the sash causing air gap deviations from the normal size in the known cases can only be eliminated if the opening devices have additional adjustment means for varying the effective length of the opening arm, which, however, should usually only be actuated when the wing is sagging or sagging towards the closure side after a long period of practical use.

In addition to the fact that the different length adjustments of the extension arms to be installed with different inclination positions require laborious and time-consuming manipulations by the adjustment means, it may also happen that the adjustment amount of the length adjustment means still available after the length adjustment has been made is no longer sufficient to prevent the sagging that occurs at a later time to fix or sag the wing. This naturally results in a considerable difficulty in using the window or door in question.

The aim of the invention is to provide a pivoting or tilting window or a door of the type explained in more detail at the beginning, in which the opening device can be installed with all the inclination angles and directions of inclination for the opening arm hidden between the circumferential fold surfaces of the sash and frame without having to carry out any adjustment work.

This task is solved by
that the joint is at a downward bend or the like. The rear end of the extension arm, that its axis plane runs below the plane parallel to the extension arm of the circumferential surface of the fold of the upper wing arm,
and that the hinge - with the wing in the closed position on the fixed frame - extends at a certain distance parallel to the plane of the vertical fold peripheral surface of the fixed frame.

It has been shown that when installing an exhibiting device having these design features in rotating or tilt-and-tilt windows or doors of the generic type, practically no readjustment work has to be carried out by the distance provided on the joint side - the so-called rebate clearance - to be observed between the rebate circumferential surfaces of the sash and the fixed frame.

It has proven particularly useful according to the invention if the axis plane of the joint lies approximately on the extension plane of the underside of the wing-side holding and guide rail for the extension arm and furthermore the axis distance of the joint from the plane of the vertical fold circumferential surface of the fixed frame is approximately half the distance between corresponds to the circumferential surface of the sash and fixed frame.

The invention further provides that the joint connects the extension arm to the upper end of an intermediate plate, which in turn is seated on the end leg of an angled plate extending from a joint sleeve, the joint sleeve being held pivotably about the vertical axis in the bearing block.

The joint arranged and designed according to the invention can - in the sense of DE 37 02 957 C1 - also be releasably and length-adjustable connected to the extension arm by means of a shaped piece and, moreover, can be positively locked with this by means of a locking bracket which can be displaced about the joint at the upper end of the intermediate plate .

With these means, it is possible to combine raising arms of various designs and / or lengths with differently profiled and dimensioned angle plates of brackets with a joint sleeve, thereby making the raising devices easy and with little work to meet different needs and purposes, in particular those that differ in their shape Window and door profile systems to adapt.

If the intermediate plate can be turned or pivoted in its mounting plane by 180 ° to the end leg of the angle plate starting from the joint sleeve and forming a bracket, as is already known, for example, according to DE 37 02 957 C1, then one and the same opening device can be easily installed Set or pre-assemble for optional right and left hinges.

It is also within the scope of the invention to provide a generic rotating or tilting window or a door with an opening device which is suitable for assigning both right and left sashes.

This is achieved according to the invention in that the intermediate plate is mounted on the end leg (28) of the angle plate (27) so that it can be pivoted through 180 ° about an axis directed transversely to its plane and can be locked with the latter in each of its two possible end pivot positions (81, 82, 83).

A further embodiment provides that the axis is formed by a clamping screw seated in a thread of the end leg and the intermediate plate can be locked with the end leg in both end pivot positions via a pin / hole connection (81, 82, 83).

It is also advantageous if the clamping screw cannot be lost, e.g. is held in the thread of the end leg by upsetting their shaft end.

In the case of rotating or tilting windows or doors of the generic type, it is of considerable advantage if the fastening position of the frame-side bearing block for the opening device on the room-side end face of the fixed frame can be determined by means of a teaching device. Therefore, the invention provides that the teaching device on the bottom of its against the room-side end face of the fixed frame and the determination or Attachment of the fastening points useful gauge plate carries a stop block, which on the one hand has a main stop that can be placed against the vertical fold circumferential surface of the fixed frame, and on the other hand has a directional stop surface that is curved in a circular arc, which can be placed against the upper - horizontally or inclined - fold circumferential surface of the fixed frame .

The lateral distance of the arch center of the straightening stop surface from the plane of the main stop corresponds to the predetermined center distance of the joint from the vertical circumferential fold surface of the fixed frame, while the radius of the straightening stop surface around this center of the arch to the length of the downward-directed angling supporting the joint is matched at the rear end of the extension arm.

It has been shown that, with the help of such a jig device, the frame-side bearing block for the display device can in any case be determined exactly on the frame-side end face of the fixed frame, regardless of whether the upper horizontal legs of the sash and the fixed frame are at right angles , connect at an acute angle or at an obtuse angle to the adjacent, upright leg. The straightening arc-shaped straightening stop surface on the stop block of the jig device comes to the straightening system in any case against the frame rebate peripheral surfaces oriented normal to the main plane of the frame in the relevant corner zone area.

An optimal configuration results if the jig device with jig plate and stop block is designed symmetrically to a transverse plane normal to the level of the fixed frame, because then and the same teaching device is suitable for right and left use.

Precautions in natural size as well as in front and side view, which facilitate the optional right and left hinging of one and the same display device.

The different designs of tilt-and-turn windows or doors shown in FIGS. 1 to 3 each have a fixed frame 1 and a wing 2. The wing 2 can be relative to the fixed frame 1 either about a lateral vertical axis 3- 3 in Rotation position or open about a lower horizontal axis 4-4 in the tilt position. In order to enable these different opening positions, the wing 2 is usually supported on the fixed frame 1 at the intersection of the two axes 3-3 and 4-4 by a corner joint 5. For the purpose of pivotally opening the wing 2, a pivot joint 6 is additionally provided in the area of the hinge axis 3-3 at the upper corner of the fixed frame 1 and the wing 2, while for tilt opening in the area of the hinge axis 4-4 at the corner opposite the corner joint 5 the fixed frame 1 and the wing 2, a tilt joint 7 can be made effective.

The swivel joint 6 and the swivel joint 7 can be actuated together by an engagement swivel-tilt fitting 8 such that the swivel joint 6 is engaged when the swivel joint 7 is in the disengaged position and vice versa. The wing 2 resting on the fixed frame 1 in the closed position can also be locked in its closed position by means of the engagement rotary tilt fitting 8.

In the turn-tilt windows or doors shown in FIGS. 1 and 2, the engagement turn-tilt fitting 8 consists of a lock-side drive rod 9, which can be moved by an operating hand lever 10 and not only actuates locking members 11 for the wing 2 in the closed position, but also the tilt joint 7 engages and disengages and from an upper drive rod 12 through which the pivot joint 6 can be disengaged and engaged. Both drive rods 9 and 12 are connected to one another by a corner deflection 13 which is installed on the upper wing corner on the lock side.

In the exemplary embodiment of a tilt-and-turn window or a tilt-and-turn door according to FIG. 3, the engagement-tilt-and-turn fitting 8 again consists of a connecting rod 9 installed on the lock side in the wing 2, which is operated by the operating hand lever 10 is moved and the lock-side locking members 11 actuated for the wing 2. The drive rod 9 is connected to a further drive rod 15, which is installed in the lower horizontal wing leg and engages and disengages the tilt joint 7, via a corner deflection 14 installed on the lower wing corner on the lock side. This drive rod 15 is in turn connected via a corner deflection 16 to a drive rod 17 guided in the upright wing spar on the swivel joint side, to which a corner deflection 18 connects at the top, which the swivel joint 6 is able to move in and out.

In all of the exemplary embodiments of turn-tilt windows or doors shown in FIGS. 1 to 3, an opening device 19 is installed between the upper frame leg 1 'and the upper wing leg 2'. This deployment device 19 is articulated with its deployment arm 20 in the lateral vertical axis 3-3 by the swivel joint 6 on the fixed frame 1, while the deployment arm 20 on the other hand can be pivoted and pushed on the upper leg 2 'of the wing 2 with a (from 1 to 3 not visible but explained later) holding and guide rail 32 is operatively connected.

A second support point for the wing 2 on the opening device 19 is formed in the exemplary embodiments shown in that an additional arm 22 on the one hand on the raising arm 20 and on the other hand on the upper wing leg 2 'or on the holding and guide rail 32 only pivotally engages.

The raising arm 20 and the additional arm 22 cooperate approximately in the manner of the known elliptical link to form the raising device 19.

The second support point for the wing 2 on the opening device 19 can also be created in other known ways. This is particularly the case when it comes to windows and doors that are hinged only as so-called swing windows or doors with only vertical axis 3-3.

The swivel joint 6 between the wing 2 and the fixed frame 1 is formed by the opening device 19 according to FIGS. 1 to 3. In this case, the opening arm 20 can be opened relative to the fixed frame 1 in the vicinity of the vertical axis 3 - 3 either by the drive rod 12 (FIGS. 1 and 2) or by the corner drive 18 (FIG. 3) in its parallel position in order to open the wing 2 be locked to the upper wing leg 2 'in a known manner.

To tilt the wing 2 about the lower horizontal axis 4-4, on the other hand, the raising arm 20 of the raising device 19 - also in a known manner - is uncoupled from the upper wing leg 2 'in the vicinity of the vertical axis 3-3, so that it is between this wing leg 2 'and the associated frame leg 1' can be inclined in its plane of movement. The opening device 19 limits the tilt opening width for the wing 2 on the one hand via the guide projection 21 of the opening arm 20 and on the other hand via the additional arm 22.

In the present case, it is mainly a matter of expanding the area of application of the opening device 19, which is arranged essentially concealed between the fold peripheral surfaces of the upper frame leg 1 'and the upper wing leg 2', in the case of turn-and-turn or tilt and turn windows or doors. The use of the opening devices 19 should not only be possible in the case of turn-and-tilt windows or doors of the generally customary type, that is to say with frame and wing legs directed at right angles to one another, as can be seen in FIG. 2. Rather, their application should also can be achieved for pivoting or tilt-turn windows or doors in which at least the upper frame legs 1 'and wing legs 2' have a course inclined in their plane against the horizontal, as can be seen in FIGS. 1 and 3. The latter type of turn-and-tilt windows or doors is required, for example, for installation directly under sloping ceilings, preferably on the gable side of roof studios.

It is therefore important to specify raising devices 19 which can be easily adapted to the respective course of the upper frame leg 1 'and the upper wing leg 2' when the raising arm 20 is articulated in the region of the lateral vertical axis 3-3. In direct connection to the lateral vertical axis 3-3, the raising arm 20 of the raising device 19 should be able to be aligned both horizontally (FIG. 4) and with a negative inclination (FIG. 4) or a positive inclination (FIG. 2).

4, 6 and 8 each show in a detailed representation that area of the opening device 19 and the associated turn-tilt fitting 8, which ensures their different installation options according to FIGS. 1 to 3.

5, 7 and 9, on the other hand, each show in cooperation with a fixed frame 1 the use of a jig device 42 with the aid of which the mounting position of the frame-side bearing block 23 for the opening device on the room-side end face of the fixed frame 1 for the different types of windows and doors according to FIGS. 1 to 3 can be determined exactly.

4, 6 and 8, the upper pivot 6 of a tilt and turn window or a tilt and turn door is shown in operative connection with an opening device 19. It instructs the fixed frame 1 in alignment with the lateral vertical axis 3-3 attached bracket 23, in which a boom 25 is pivotable about an axle pin 24. The cantilever 25 consists of a joint sleeve 26 comprising the axle bolt 24, to which an angle plate 27 is connected in one piece. This reaches with its end leg 28 from the area in front of the room-side end face of the fixed frame 1 into the so-called rebate clearance 29, which is determined on the one hand by the rebate peripheral surface 30 of the stationary frame 1 and on the other hand by the rebate peripheral surface 31 of the wing 2. A corresponding rebate clearance 29 'is also present between the rebate peripheral surface 30' of the upper frame leg 1 'and the rebate peripheral surface 31' of the upper wing leg 2 '. In the rebate clearance 29 'between the rebate peripheral surface 30' of the upper frame leg 1 'and the rebate peripheral surface 31' of the upper wing leg 2 'is not only the display device 19 with its extension arm 20 and additional arm 22. The rebate peripheral surface 31' of the upper wing leg 2 'borders rather, with its upper side, the holding and guide rail 32 fastened on the wing side - already mentioned above - with its upper side, as is clearly shown in FIGS. 4, 6 and 8. This - also referred to as a faceplate - holding and guide rail 32 is usually equipped on the one hand with a longitudinal guide slot (not shown) for the pivotal engagement of the guide projection 21 at the front end of the extension arm 20 and on the other hand (also not shown) has a bearing hole for the only pivotable Articulation of the additional arm 22 to ensure a load-bearing function of the opening device 19.

An intermediate plate 33 is located on the end leg 28 of the angled plate 27 extending as a cantilever 25 from the articulated sleeve 26 and projects above the upper end of the angled plate 27 with an articulated eye 34. Together with the articulated eye 34 of the intermediate plate 33, matching articulated eyes 35 form on an in substantially downward leg 36 of a shaped piece 37 after insertion of a common axle pin 38 a joint 39. Its axis extends both transversely to the lateral vertical axis 3-3 or to the axle pin 24 and transversely to the longitudinal direction of the opening device 19. The length is 40 the downward bend 36 on the shaped piece 37 is dimensioned such that the axial plane of the joint 39 extends by a minimum amount, for example of several millimeters, below the plane of the circumferential circumferential surface 31 'of the upper wing arm 2 which is parallel to the raising arm 20 or the raising device 19.

A position of the axis plane of the hinge 39 is preferred, for example on the extension plane of the underside 32 ′ of the wing-side holding and guide rail 32, as can be seen in FIGS. 4, 6 and 8.

In addition, it is important that when the wing 2 is in the closed position on the fixed frame 1, the center distance 41 of the joint 39 parallel to the plane of the vertical fold circumferential surface 30 of the fixed frame 1 is approximately equal to half the air gap distance 29 between the fold circumferential surfaces 30 and 31 of the fixed frame 1 and wing 2 is dimensioned, as can also be seen in FIGS. 4, 6 and 8.

In the manner still to be explained below, the shaped piece 37 having the bend 36 can be held in a detachable connection with the raising arm 20 of the raising device 19, although it is also readily possible for this bend 36 with the bearing eye 34 for the joint 39 to also be in one piece to be provided at the rear end of the extension arm 20. In any case, however, it is essential to dimension the length 40 of the bend 36 on the extension arm 20 provided with the hinge eyes 35 for the hinge 39 so that the axis plane of the hinge 39 is in every possible alignment position of the opening device 19, that is both with horizontal extension (FIG. 2) and with a negative inclination (FIG. 1) or positive inclination (FIG. 3) below the respective plane of the circumferential fold surface 31 'of the upper wing leg 2'. It has been shown that with this special arrangement of the transverse joint 39 using a special gauge device 42, as shown in FIGS. 5, 7 and 9, the mounting position of the frame-side bearing block 23 for the opening device 19 on the room side End face of the fixed frame 1 can be determined easily and exactly for each of the window and door designs shown in FIGS. 1 to 3.

The jig device 42 has a jig plate 43 that can be placed against the end face of the fixed frame 1 on the room side, which is symmetrical to a transverse plane 44-44 that is normal on the level of the fixed frame 1 and each has a certain number of marking openings and drill bushings 45, 46, 47 contains which lie on a fastening plane 48-48 which intersects the transverse plane 44-44 at right angles and is also normal on the plane of the fixed frame 1.

On its underside, the gauge plate 43 is equipped with a stop block 49. On the one hand, this has a main stop 50 which can be placed against the vertical fold peripheral surface 30 of the respective fixed frame 1 - preferably has a relatively large longitudinal extension. On the other hand, it has a directional stop surface 51 which adjoins it essentially in the transverse direction and is curved in a circular arc and which acts against the fold peripheral surface 30 'of the upper leg 1' is applied to the fixed frame 1. An important feature of the directional stop surface 51 is that its arc center 52 has a side distance 53 from the main stop 50, which is essentially at the center distance 41 of the joint 39 from the vertical fold peripheral surface 30 of the fixed frame 1 matches, while its radius of curvature 54 is dimensioned somewhat larger than the length 40 of the bend 36 at the rear end of the extension arm 20.

The teaching device 42 designed and used in this way, in conjunction with the opening device 20 having the special arrangement and design of the joint 39, ensures that the striking work on a window or door is carried out correctly at all times, regardless of which of the designs shown in FIGS. 1 to 3 or it has.

5, 7 and 9 of the drawing show that the stop block 49 of the teaching device 42 with the main stop 50 and directional stop surfaces 51 is designed symmetrically to the transverse plane 44-44. One and the same gage device 42 can therefore be used both for right and left stop of an opening device 19.

10, 11 and 12 of the drawing, it can be demonstrated that it can be advantageous to design the display devices 19 in the vicinity of the frame-side bearing block 23 on the extension arm 20 with a transversely directed joint 39 so that their functional parts - In a manner similar to DE 37 02 957 C1 - not only can it be produced particularly simply and economically and, with high stability, only require a small installation space, but at the same time also a problem-free length adjustment of the extension arm for the purpose of adjusting the wing relative to the fixed frame enable. It is also expedient to enable quick and functionally reliable replacement of the opening devices 19 relative to the brackets 25 equipped with the joint sleeve and the angle plate by simple plug-in coupling connections and thus to bring about a problem-free adaptation to different installation conditions.

The shaped piece 37 is used according to FIGS. 10 to 12 of the drawing as a connecting member between the extension arm 20 and the intermediate plate 33 located on the end leg 28 of the angle plate 27, and this by means of the transverse joint 39. Therefore, this shaped piece 37 also has a the arm 55 associated with the extension arm 20, which extends essentially at right angles to the bend 36.

The shaped piece 37 is fork-shaped in the region of its leg 55 and the bend 36 - viewed from above. In other words, it has two cheeks that run parallel to one another at a distance, each with an upright flat cross-section that extends not only over the length region of the leg 55, but also over the bend 36 into the region of the bearing eyes 35 thereof.

On the inside of each cheek of the leg 55 there is an inwardly projecting nose 56 immediately in front of the transition region into the bend 36, while the leg 55 of the molded piece 37 continues from a fork web 57 in the forward direction as a longitudinally arranged, laterally offset tongue 58 .

While the largest width dimension of the shaped piece 37 in the region of the cheeks extending over the leg 55, the bend 36 and the bearing eyes 35 is matched to the width of the extension arm 20, the tongue 58 projecting longitudinally from the fork web 57 only has a width which is approximately corresponds to a third of the width of the extension arm 20.

The extension arm 20 is provided at its rear end with a nose 59 which is arranged in the center and is also offset laterally. In addition, the extension arm 20 has an offset 60 which is oriented essentially transversely to its plane with a course such that the upper side of the end section 63 carrying the nose 59 lies approximately around the thickness of the tongue 58 of the shaped piece 37 than the lower side of the extension arm 20 in front of the offset 60.

Over a length section 61 slightly exceeding the arrangement area of the offset 60 in both directions, the extension arm 20 contains a slit-like cutout or opening 62 lying in the middle, the two ends of which are indicated by dash-dotted lines in FIGS. 10 to 12 of the drawing. The width of this cutout or opening 62 is matched to the width of the tongue 58 on the shaped piece 37 with little side play. The tongue 58 of the shaped piece 37 can be brought into longitudinally sliding guide engagement with the cutout or opening 62 of the extension arm 20, as can be seen from each of FIGS. 10 to 12.

In the area between its cutout or opening 62 and the nose 59, that is to say on the end section 63, the extension arm 20 carries a projection 64 projecting out of its plane in the direction of the offset 60, the width of which is matched to the clear distance between the fork cheeks on the leg 55 of the fitting 37 is.

In a threaded hole 65 of the extension 64 parallel to the longitudinal direction of the extension arm 20, a screw member 66 is rotatable and thereby axially displaceably held, which has a thickened head part 67 at its rear end. In the free end face of this head part 67 there is a tool engagement 68, for example a polygonal recess in the form of an internal hexagon.

The length dimension of the screw member 66 is based on the distance between the rear side of the fork web 57 and the side surface of the inwardly projecting lugs 56 facing it of the fitting 37 matched, as can be clearly seen in FIGS. 10 to 12 of the drawing.

The detachable coupling of the shaped piece 37 with the extension arm 20 takes place through the successive work steps shown in FIGS. 10 to 12 of the drawing.

After the tongue 58 of the molded part 37 has been inserted into the cutout or opening 62 in the region of the offset 60 of the extension arm 20, the shoulder 64 with the screw member 66 can be inserted from the inside of the leg 55 between its parallel cheeks. The front end of the slide member 66 comes into operative connection with the fork web 57 which forms an abutment therefor, while the end surface of the thickened head part 67 comes into active connection with the side surface of the lugs 56 adjacent to it. At the same time, the tool engagement 68 comes to lie in the area between the ends of the lugs 56 facing each other at a distance and is therefore accessible from the area of the bend 36 through the space between the two fork cheeks with a pin-like tool (hexagon socket wrench) for the purpose of actuation.

By rotating the screw member 66 in the threaded hole 65 of the neck 64, this can be axially adjusted in the neck 64. Because it interacts on the one hand with the fork web 57 and on the other hand with the lugs 56 of the shaped piece 37, a corresponding longitudinal displacement of the extension arm 20 on the shaped piece 37 can thereby be brought about. These can be used to regulate the installation position of the wing 2 relative to the fixed frame 1.

The detachable coupling possibility between the extension arm 20 and the shaped piece 37 makes it possible without further ado devices 19 of different designs and If necessary, bring the length into operative connection with differently designed brackets 25 for the upper swivel joint 6 of a window or door leaf 2, in order thereby to take account of the most varied of requirements.

To secure the coupling connection between the extension arm 20 and the fitting 37, the intermediate plate 33 interacts with the nose 59 on the end section 63 of the extension arm 20 via its bearing eye 34 by means of the transverse joint 39.

Namely, the bearing eye 34 is provided with an opening 69 in the direction of the rear of the intermediate plate 33 up to the circumference of the axle bolt 38 over a central region adapted to the width of the laterally offset nose 59. As a result, the peripheral region of the articulated eye 34 which adjoins the opening 69 to the front forms a, to a certain extent, shell-like locking bracket 70. It can also be seen from FIGS. 10 to 12 of the drawing that the outer circumference of the locking bracket 70 is set back somewhat from the outer circumference of the remaining part of the hinge eye 34, so that a groove 71 is formed there over a partial circumference of the locking bracket 70.

For locking the extension arm 20 with the shaped piece 37, the intermediate piece 33, together with the bracket 25 of the upper swivel joint 6 carrying it, is pivoted up into the angular position shown in FIG. 10. As a result, the free end 72 of the locking bracket 70 adjacent to the opening 69 comes into a position in which it can be guided past the rear end of the nose 59. By pivoting back the intermediate piece 33 about the joint 39 from the position according to FIG. 10 via the position according to FIG. 11 into the position according to FIG. 12, the nose 59 is then gripped by the locking bracket 70 on its underside and can be seen in FIG. 12 Relative position to the fitting 37 positively determined. So that fulfills transversely directed joint 39 to a certain extent a dual function on the opening device 19.

13 shows in an exemplary embodiment and in a view from the front an advantageous further development of the shaped piece 37 with the intermediate plate 33 articulated thereon, the angle plate 27 and the joint sleeve 26 on an enlarged scale.

In order to be able to set or preassemble the opening device 19 for optional right and left stop, the end leg 28 is connected there to the intermediate plate 33 by a clamping screw 75 forming a pivot axis. The clamping screw 75 is provided at its shaft end 76 with a rivet head-like deformation 77. This is formed by upsetting the clamping screw 75 after it has penetrated both the intermediate plate 33 and a thread 78 of the end leg 28. A perforation 79 is provided on the intermediate plate 33, which ends in a depression 80 on the side facing away from the end leg 28 and serves for flush reception of the countersunk head of the clamping screw 75 when it is firmly tightened into the threaded hole 78.

The illustrated embodiment shows the delivery state of the assembly, in which the clamping screw 75 in the recess 80 still has a certain amount of play, so that the intermediate plate 33 can be lifted from the end leg 22 by the amount of the play, so that it can pivot about the clamping screw axis .

On the side of the intermediate plate 33 facing the end leg 28 there is a material projection 81 which, depending on the installation position, can be inserted into one or the other recess 82 or 83 of the end leg 28 in order to prevent an undesired pivoting movement of the intermediate plate 33 relative to the end leg 28. As already mentioned, the intermediate plate 33 can be pivoted through the clamping screw 75, which acts as an axis, by 180 ° and in each of its two possible end pivot positions with the end leg 28 can be locked in a rotationally fixed manner by engaging the material projection 81 in one of the recesses 82 and 83.

The clamping screw 75 is held captive in the thread 78 of the end leg 28 by upsetting the deformation 77 at its shaft end 76 and can also by z. B. improper handling cannot be released from the connection.

The arrangement of the individual active components also ensures that the engagement of the material projection 81 in one of the recesses 82 or 83 is still secured even when the clamping screw 75 is loosened, because the weight forces of the wing act in the direction 84 and thus support an automatic engagement. However, the clearance between the clamping screw 75 and the countersink 80 in the preassembled state is so large that the material projection 81 can be completely disengaged from the recess 82 or 83 in order to enable the pivoting.

In order to achieve the complete disengagement of the material projection, it is advantageous that the clamping screw 75 not only allows pivoting in the plane of the end angle 28, but also allows a slight pivoting movement perpendicular to it. The necessary play between the clamping screw 75 and the intermediate plate 33 can thereby be reduced, whereby the required length of the clamping screw 75 can also be minimized. The shaft end 76 of the clamping screw 75 therefore protrudes only slightly beyond the outer surface of the end bracket 28 in the tightened state.

FIG. 14 shows the arrangement of FIG. 13 in a side view, the end leg 28 being shown pivoted by only 90 ° relative to the intermediate plate 33. It can be clearly seen that the recesses 82 and 83 line with the central axis of the clamping screw 75. In the exemplary embodiment, the recesses 82 and 83 are designed as perforations and the material projection 81 as pins. It can also be seen from this illustration that the deformation 77 of the shaft end 76 of the clamping screw 75 is greater than the inside diameter of the thread 78, so that the clamping screw 75 cannot be removed from the end leg 28.
