EP0803627A2 - Fitting for pivoting and tiltable wings with variable ventilation gap - Google Patents

Abstract

The fitting comprises a drive rod (2) which is guided along a rail (1) to which is linked a pivoting and movable pull-out arm (3). A support link (4) is arranged between the arm and the rail. A locking device (8), between the rail and the support link blocks or releases the swivel movement of the link, in relation to the displacement of the drive rod. The locking device has at least one blocking lever (10,11) pivot mounted on the rail and operated by a control cam (16) on the drive bar. The levers engage with a pinion (9) on the axle of the support link, and are mounted on adjacent bearing pins (12,13) on the rail.

Description

The invention relates to a turn-and-tilt fitting for windows, doors and the like with a drive rod guided on a faceplate and a pivoting and displaceably articulated extension arm on the faceplate and a support arm provided between the extension arm and the faceplate and with an arrangement for determining the sash in predeterminable tilting angle positions .

By means of turn-tilt fittings, it is possible to pivot the sashes of windows, doors and the like about a vertical axis, to tilt a horizontal axis and to lock them in the closed position on the respective frame. It is known to use additional fitting parts in connection with such turn-tilt fittings, which make it possible to hold the respective wing in a so-called night ventilation position, i.e. in a position in which the wing is tilted about a horizontal axis, but not the occupies the maximum tilt opening position resulting from the turn-tilt fitting, but is held at a lower tilt angle, so that the sash is only opened in the form of a gap, in particular for ventilation purposes. A disadvantage of the known solutions is not only the need for additional components and thus also additional assembly work, but also that the corresponding elements require an additional operation which is separate from the normal sash actuation.

The object of the invention is therefore to design a turn-tilt fitting of the type specified in such a way that a determination of the respective wing in a night ventilation position is made possible in a simple and user-friendly manner.

This object is achieved according to the invention essentially in that a locking device is effective between the faceplate and the support arm that blocks or releases the pivoting movement of the support arm depending on the adjustment of the drive rod.

Through these measures, the function of locking the sash in a night ventilation position is integrated into the function of the turn-tilt fitting and thus it is possible that the turn-tilt fitting is not only adjustable or switchable between closed, turning and tilting position, but that as a further possible position, there is the gap ventilation position, the fitting between these positions being operable in the usual manner by means of the handle connected to the connecting rod gear.

Preferably, the locking device comprises at least one blocking lever pivotally mounted on the faceplate, which can be actuated via a control cam provided on the drive rod and can be brought into locking engagement with a pinion or the like, which is attached in a rotationally fixed manner to the supporting link axle which is fixedly connected to the supporting link. Instead of a pinion connected to the support link axle, the support link axle itself can also take over the function of the pinion by suitable design of the end part.

By blocking or releasing the rotational movement of the support link axle and thus the pivoting movement of the support link, it is possible in a particularly simple manner to achieve a variable night ventilation position for the respective wing, whereby an extremely compact arrangement can be achieved due to the blocking and release of the rotary movement of the support link axle.

The pivotally mounted locking levers can be designed in the manner of a clamping scissor encompassing the pinion, with a free-stroke section for the control cam provided on the drive rod and a clamping-stroke section, in which the control cam is spread apart, ensuring the free rotation of the pinion between the blocking lever legs facing away from the pinion Blocking lever arm closes the clamping pliers arm and thus locks the pinion.

Accordingly, if the actuating handle of the turn-tilt fitting is brought into the position corresponding to the tilt position, for example pointing vertically upward, then the wing can be pivoted about its horizontal pivot axis in the usual way, although it is integrated into the rotary device by the inventive integration of the night ventilation devices. Tilt fitting is possible to determine the sash in the desired position between the closed position and the maximum tilt opening position by moving the handle slightly from the vertical position corresponding to the tilt switch position in the direction of the swivel switch position. A slight pivoting of the handle in this direction and thus a corresponding displacement of the drive rod leads to the blocking of the support arm and thus to the locking of the wing in a partially tilted position. This determination can be released again simply by moving the actuating handle into the toggle switch position and so that the sash can be transferred either to the full toggle position or to the closed position.

Particularly advantageous embodiments of the invention are specified and shown in the subclaims, the description and the drawing.

FIG. 1 shows a turn-tilt fitting in the area of a stay scissors for a wing, specifically a faceplate 1 to be fastened in a wing groove and on which a drive rod 2 is guided so as to be longitudinally displaceable. On the faceplate 1, an extension arm 3 is mounted via a swivel-sliding joint 5, and this extension arm 3 is connected via a pivot axis 6 to a supporting link 4 which, with the extension arm 3 in relation to the faceplate 1 in the extended state of the extension arm 3, forms an obtuse angle includes and with its end facing away from the exhibiting handle 3 is mounted on the faceplate 1 via an axis 7. The support arm axle 7 is connected to the support arm 4 in a rotationally fixed or rigid manner and extends into the space between the faceplate 1 and drive rod 2 which is created by an offset of the faceplate 1. At the projecting end, the support arm axle 7 is preferably designed as a toothed or corrugated pinion 9 or with such a pinion 9 rotatably connected.

Between the faceplate 1 and the support arm 4, a locking device 8 is effective, which is arranged between the faceplate 1 and the drive rod 2 and, depending on the position of the drive rod 2, releases or blocks the pinion 9.

This locking device 8 comprises - as this is shown in particular in the top view according to FIG. 2 - a first blocking lever 10, which is mounted on the faceplate 1 via a bearing pin 12, and a second blocking lever 11, which is also mounted on the faceplate 1 via a bearing pin 13 , so that a pair of two-armed levers 10, 11 is present which, on one side of the bearing pins 12, 13, encompass the pinion 9, which is connected in a rotationally fixed manner to the supporting link axle 7, with its clamping pliers limbs 17, 18 and whose legs facing away from the pinion 9 have a free stroke distance between them 14 and a clamping stroke distance 15, in which a control cam 16 can be moved, which is provided on the drive rod 2 and can consist, for example, of a corresponding configuration, as shown in FIG. 1.

The width of the free stroke section 14 corresponds approximately to the diameter of the control cam 16, so that it can be moved in the free stroke section 14 without actuating the blocking levers 10, 11.

The width of the clamping stroke path 15 is less than the diameter of the control cam 16, so that when the control cam 16 penetrates the clamping stroke path 15 with a corresponding adjustment of the drive rod 2, the legs of the two blocking levers 10, 11 are spread apart and thus the clamping forceps legs are closed 17 and 18 takes place, which is synonymous with blocking the pinion 9 and thus a determination of the support arm 4 and Ausstellenker 3.

Figure 3 shows the turn-tilt fitting according to Figure 1 in a night ventilation position.

The extension arm 3 is fixed at a small tilt angle via the support arm 4, since its axis 7 is blocked by the locking device 8 and thus the wing coupled to the extension arm 3 is kept stable and immovable via the triangular connection of the extension arm 3, support arm 4 and faceplate 1 .

The blocking of the support arm 4 via the pinion 9 is a consequence of the fact that the control cam 6 has been brought into the region of the clamping stroke section 15 via the connecting rod 2 and thus the clamping jaw legs 17, 18 have been closed.

Figure 4 shows the turn-tilt fitting in the full tilt opening position, the control cam 16 having been moved to the left via the connecting rod 1 from the region of the clamping stroke section 15, so that the clamp leg 17, 18 could open again and thus the wing was released from the gap ventilation position has been.

FIG. 5 shows on the one hand the representation of the detail X from FIG. 3 and on the other hand the representation of the detail Y from FIG. 4.

The representation of the detail X corresponds to the blocking of the pinion 9 by the clamp leg 17, 18, that is, the determination of the turn-tilt fitting in a night ventilation position. In this case, toothings or corrugations on the clamp pliers limbs 17, 18 engage in corresponding toothings or corrugations of the pinion 9 which is connected in a rotationally fixed manner to the support link axle 7 and thereby prevent any further rotation of this pinion 9 and thus the support link axle 7 which is rigidly connected to the support link 4.

The detailed representation Y shows the case of the freely rotatable pinion 9, which is either not in engagement with the clamping pliers legs 17, 18 or at least is not prevented from rotating by these clamping pliers legs 17, 18. This is always the case when the control cam 16 connected to the drive rod 2 is not in the region of the clamping stroke section 15 and the wing can accordingly be tilted freely.

The locking device 8 described, like the embodiment variants to be described, can be realized in a very space-saving manner and integrated into the normal structure of such a fitting without impairing the other functions of the turn-tilt fitting.

In the embodiment variant shown in FIG. 6, a type of clamping tongs arrangement is again used for the locking device 8, but in this embodiment variant, instead of clamping pincer legs encompassing the pinion 9, the locking levers 10, 11 have toothed or corrugated end faces 21, 22 which are formed on the corresponding lever arms can be brought into contact with the pinion 9 in a blocking manner. In this case, the pinion 9 has a larger advantage in terms of the holding forces that can be achieved Diameter that can correspond approximately to the faceplate width.

The two blocking levers 10, 11 lie in their longitudinal extension on either side of the faceplate middle, but are each supported by a corresponding extension on bearing journals 12, 13 located in the other faceplate half, these bearing journals 12, 13 mutually simultaneously providing a pivoting movement limitation for the two in the storage area in different blocking levers 10, 11 form. On the connecting rod side, lugs 19, 20 are provided on the blocking levers 10, 11 in the region of the toothed end faces 21, 22, between which an expansion lug 25 provided on the connecting rod 2 enters in the full tilted position and the blocking levers 10, 11 define out of engagement with the pinion 9 can hold.

FIG. 7 shows the turn-tilt fitting according to FIG. 6 in a night ventilation position. The control cam 16 is located in the region of the clamping stroke section 15, as a result of which the toothed end faces 21, 22 of the blocking levers 10, 11 are pressed against the pinion 9, which in the manner already explained results in a locking or blocking of the extension arm 3.

FIG. 8 shows the turn-tilt fitting in the tilt-open position, the locking device 8 being ineffective since the control cam 16 is outside the clamping stroke section 15 and the two blocking levers 10, 11 are disengaged from the pinion 9 via a spreading attachment 25 provided on the drive rod 2 being held. In this case, the expansion lug 25 presses against the two lugs 19, 20 on the blocking levers 10, 11.

FIG. 9 shows a further embodiment variant of the invention, in which a special control link 24 is provided for actuating the blocking levers 10, 11 on the drive rod 2 in a region that is cranked downwards.

In particular, FIG. 10 shows that on the faceplate 1 the locking pin 10, 11 surrounding the pinion 9 in the form of clamping jaws with actuating projections 19, 20 which extend in the direction of the drive rod 2 and are located in the region of the free ends of the clamping jaws, are movably mounted, specifically Via a blocking lever end part 23 provided on the end facing away from the pinion 9. The blocking levers 10, 11 in the area of the pinion 9 are provided with teeth or corrugation by the interaction of their actuating approaches 19, 20 with a control link 24 between a release and a Blocked position reversed. In the control link 24, this embodiment variant is a separate part, which is also shown separately in the drawing and is preferably riveted to the drive rod 2. The actuating lugs 19, 20 engage in this control link 24, and a free-stroke section 14 and a clamping stroke section 15 which is narrower in comparison therewith are provided in the control link 24 for these actuating approaches 19, 20. In addition, the control link 24 has an end-side expansion lug 25 which can be inserted between the actuation lugs 19, 20.

FIG. 11 shows the embodiment variant according to FIG. 9 in a night ventilation position, in which case the actuating approaches 19, 20 of the blocking levers 10, 11 are located in the region of the narrow clamping stroke distance 15 of the control link 24 and the blocking levers 10, 11 are thus tensioned against the pinion 9 and as a result, pinion 9 and support arm 4 are locked against any movement.

Figure 12 shows the turn-tilt fitting according to Figure 9 in the full tilt opening position, in this position there is free rotation of the pinion 9, since the expansion lug 25 of the control link between the actuating lugs 19 and 20 of the blocking levers 10, 11 and these blocking levers 10, 11 apart so that there is no engagement with the pinion 9.

In the embodiment according to FIGS. 9 to 12, the control link 24 is designed as a separate part which can be connected to the drive rod 2, but it is equally possible to provide the control link directly by corresponding impressions in the drive rod 2, so that the use of a separate part is superfluous and no cranking of the drive rod in the area of the locking device 8 is required.

FIG. 13 shows an embodiment variant in which the pinion 9, which in turn has a diameter approximately corresponding to the faceplate width, is locked and released via a lever wedge arrangement. For this purpose, a displaceably mounted clamping member 27 is provided adjacent to the pinion 9 and can be actuated via a two-armed adjusting lever 29. This adjusting lever 29 is pivotally mounted on the faceplate 1 via a bearing pin 12 and is provided in the region of its long lever arm 31 with a control link recess 32, in which the control cam 16 provided on the drive rod 2 engages. The control lever 29 is pivoted due to the curved shape of the control link recess relative to the longitudinal axis of the drive rod 2 depending on the drive rod position. This pivoting causes an axial movement of the clamping member 27 via a wedge engagement between the short lever arm 30 of the actuating lever 29 and the clamping member 27, which is displaceable between guides 28, so that this clamping member 27 is either blocking engages with the pinion 9 or releases the pinion 9 for rotation.

Due to the design of the control link recess, which can be seen in plan view in FIG. 14, a high pressing force for the clamping member 27 and thus a high holding force in the gap ventilation position can thus be achieved due to the resulting lever ratios.

FIG. 15 shows the turn-tilt fitting according to FIG. 13 in a night ventilation position. The control cam 16 pivots the two-armed actuating lever 29 in a counterclockwise direction and thus presses the clamping member 27 against the pinion 9 via its short lever arm 30 and thus blocks support arm 4 and pivot arm 3 in the position selected here, whereby it should be noted that in all embodiments the The size of the gap ventilation angle can be freely selected, since the pinion 9 can be blocked by the locking device 8 at any tilt opening angle.

FIG. 16 shows the turn-tilt fitting according to FIG. 13 in the maximum tilt opening position, that is to say when the locking device 8 is not effective. The short lever arm 30 has been pivoted clockwise in this position via the control link recess 32 and the control cam 16 in comparison to the night ventilation position according to FIG , which is synonymous with the removal of the blocking of the pinion 9 by the clamping member 7.

FIG. 17 shows an embodiment variant which differs from the turn-tilt fitting according to FIGS. 13 to 16 in that a toothing 33 is provided between the adjusting lever 29 and the clamping member 27 instead of a wedge engagement. This toothing 33, which preferably runs in a circular arc around the bearing journal 12, is designed such that that, depending on the pivoting of the actuating lever 29, the clamping member 27 is pressed against the pinion 9 in the blocking position or can assume the release position. In the blocking position, the teeth of the toothing 33 are in positive engagement, while in the release position there is play between these teeth which enables the clamping member 27 to move away from the pinion 9 so far that the pinion 9 can rotate freely. The advantage of this embodiment is, above all, that the force application directions are defined and that any tendency to jam can be eliminated.

All of the described design variants are characterized by a simple and space-saving design and by the fact that the desired night ventilation position can be carried out via the actuating rod actuation, that is to say by means of the normal actuation handle for the turn-tilt fitting.
