Description

The invention relates to a turn or Drehkippbeschlag for windows or doors with a device for inhibiting pivotal movements of the wing according to the preamble of claim 1.

When installing windows or doors equipped with hinged or tilt-and-turn fittings, it frequently happens that, when installed in the wall openings provided for this purpose, the windows or doors are not exactly in the vertical, i. are aligned in the solder anchored. Such installation inaccuracies are particularly noticeable in the wings of doors noticeable, which are usually larger and heavier than casement. Even small installation inaccuracies with a deviation of less than an angular degree of the vertical have the consequence that the respective window or door leaves when opening does not remain in any opening angle positions, but moves due to the gravitational force in an uncontrolled opening or closing position.

But even if on-site first an exact installation has been made, it can come in the course of the large number of operations of the window or door due to conditions on the one hand and occurring signs of wear of the rotary or Drehkippbänder on the other hand, that in the wing a tendency for self-opening or closing adjusts when he is in the rotary opening position or pivot position located. Finally, this unwanted tendency to uncontrolled, self-opening and closing can also be adjusted by the fact that a wing will always endeavor, due to its weight, to lean towards its handle or closure side.

This tendency of the wings to tilt toward the handle side over time due to their own weight results in the need to raise the wing during the closing operation to allow a proper closure. This is done by means of so-called Auflaufvorrichtungen, which have become known in multiple variants. Casserole devices are usually on the lower horizontal frame spar, the band side mounted rotary and / or Drehkippbändern turned away, arranged and cooperate with a complementarily shaped, wing-mounted element together. These runners are usually wedge-shaped or roller-shaped and partially readjustable.

In order to counteract the disturbing tendency of door and window sashes for uncontrolled opening and closing in the pivoting opening position, it is already known to provide wings with anti-rotation devices. Such anti-rotation devices are known in the form of spacer or shims made of brakeable material, in particular plastic material, which are introduced into the effective during pivoting of the wing bearing of the turn or tilt and turn fittings. By means of such rotation inhibiting washers, it is possible in principle due to the self-adjusting friction to keep the respective wing in defined rotational opening positions. A disadvantage, however, is that these Drehhemm- or brake discs show signs of wear quickly, decrease in their effectiveness and accordingly a have insufficient life. The hitherto known anti-rotation devices in which the rotation-inhibiting elements are provided with adjusting devices, have the distinct disadvantage that they are very bulky and expensive, which limits their application.

If, in addition to anti-rotation devices of the type described above, a lifting possibility still has to be provided in order to ensure a correct closure, then this is always a separate, ie. separate from the rotary inhibiting device, independent device.

From the GB 717 296 A For example, there is known a rotary fitting having a rotary inhibiting device consisting of two non-metallic, friction-generating discs.

From the DE 710 152 C a turn-tilt fitting is known in which at a pivot opening of the window sash an extension attached to the window sash runs on a stationary slideway, so that the sash is raised.

The object of the invention is therefore, starting from the above-described problem and the prior art explained a rotary or Drehkippbeschlag the type entered in a particularly economical manner in such a way that the rotation inhibiting device with optimal integration in the fitting a high and durable Has effectiveness and at the same time can take over the function of a baking device according to a preferred development.

This problem is solved by the features of claim 1.

Due to the design and positioning of the brake element outside a pivot or pivot bearing of the fitting and at a distance to Such a bearing is a permanently effective, fully integrated into the fitting rotation inhibiting device obtained. The fact that the braking surface is formed by the surface of a non-positively and positively held in a guide groove of the bearing bracket plastic part, not only a simple assembly is guaranteed, but also created a replaceability, which is synonymous with that for the particular application of a rotary or Drehkippbeschlags the optimally dimensioned plastic part can be used as the rotation inhibiting organ.

Of very particular advantage is that embodiment of the invention in which the plastic part is provided at least on one side with a ramp, which cooperates with the connecting leg at the transition of the wing from its at least substantially fully open position in the closing movement.

In this way, the plastic part is given a double function, since it can fulfill the function of a baking device in addition to the rotation inhibiting function, so that a total of a casserole occurs, which is already installed in the factory and the fitting-processor no additional work on Wing and / or frame imposed. It is thus obtained a run-on sliding brake device with a minimum of material use with a maximum of effectiveness.

Particularly advantageous embodiments of the invention are specified in the subclaims and are also explained in the description of an embodiment with reference to the drawing.

In connection with the individual figures, only those components of the illustrated fitting are explained, which are of importance in the context of the present invention.

Fig. 1 shows the lower corner bearing 1 of a rotary or rotary tilting fitting, which is designed for attachment to the frame. This corner bearing 1 has a preferably integrally formed bearing block 2, which on the back and in Fig. 1 is not visible a receptacle for a bearing pin 5 which is fixedly connected to a connecting leg 4, which in turn is fixedly attached to the wing fitting 3. The bearing pin 5 can perform in its recording in the bearing block 2 pivoting and tilting movements.

At the top of the bearing block 2, a braking surface 6 is provided, which is formed on a plastic part 7, which is held positively and non-positively in a guide groove 8 of the bearing block 2. This braking surface 6 acts with the support surface 11 to be designated underside of the Connecting leg 4 together. The braking surface may optionally be formed spherical and / or have a predeterminable compressibility.

As is also apparent from FIG. 1, the plastic part 7 has bevels on both sides with respect to the desired left-right stop, which cooperate with a corresponding inclined surface 10 on the connecting leg 4.

When the wing is moved from the 90 ° -Open position shown in Fig. 1 in the closed position, then the ramp 9 is first effective and raises the wing in the manner predefined by the plastic part 7, whereupon upon further pivoting of the wing, the braking surface. 6 takes effect, so that the wing stops in any desired open position and does not fall by itself in an open or closed position.

2 shows the plastic part 7 with the braking surface 6 and the chamfers 9 in a somewhat enlarged representation. This plastic part 7 can generally also be designed without run-on bevels 9, so that it acts as a braking surface only in all open positions as a braking surface ,

However, the preferred embodiment has ramps 9, with the result that the rotation inhibiting device can fulfill the dual function of a run-on sliding brake device.

The side view of Fig. 3 shows the engaging in a recess of the bearing block 2 bearing pin 5, which is connected via the connecting leg 4 with the wing fitting 3. To recognize in this illustration, the preferred way of securing the plastic part 7 in the bearing block 2, namely the inclusion of the plastic part 7 in the manner of a dovetail-shaped guide groove 8 in the bearing block. In this way, not only the plastic part 7 can be easily replaced with pivoted wing, but it is also possible at any time to use a plastic part 7 with respect to the bearing block higher or lower lying braking surface 6.

In the swung-open position of the wing shown in Fig. 3, the connecting leg 4 is not on the braking surface 6, but it rests on the formed on the connecting leg 4 inclined surface 10 on the corresponding ramp 9 of the plastic part 7, so that at the beginning of the closing of the Wing of the connecting leg 4 and thus raised the wing and the casserole function is realized. Only then is the braking surface 6 in its interaction with the underside provided on the connecting leg 4 supporting surface 11 effective.

It can also be seen from FIG. 3 that, due to the interaction of inclined surface 10 and supporting surface 11, the wing is always prevented from slamming in the open, approximately 90 ° position.
