Description

The invention relates to a fitting for a window, a door or the like. With at least three rotatable wings, with the features of the preamble of claim 1.

From EP-A-0 403 774 a fitting has become known for the wing of a window, with which the wing is not only pivoted when turning but also lifted off the fixed frame, i. Will get removed. In this way, a collision of a space located inside the wing flap with the fixed frame is prevented.

From US-A-1,648,331, US-A-1,713,561, UA-A-1,786,036, US-A-2,554,862, US-A-2,654,127 and US-A-4,980,947 further fittings are known, with which casements be driven when turning. When fitting the last-mentioned document, two links are present, wherein the one arm is pivotally mounted and the other arm pivotally and slidably mounted on a rail and both links are connected to each other via a pivot bearing. In this pivot bearing, however, pivots part of the window frame when opening the window to the outside, which is usually undesirable. This disadvantage is often accepted, since this fitting the wing can be opened without the To open the axis of rotation adjacent wing, which is prevented in a variety of fittings by means of a misuse safety (GFF magazine for glass, windows, facade 11/99, pages 94 and 95).

From US-A-5,964,011 and FR-A-2 685 379 the aforementioned wing is known. To easily open and close the wings, they must be easily adjustable in height, among other things.

The invention has for its object to develop a fitting of the type mentioned in such a way that the wing height is easily adjustable.

This object is achieved with a fitting having the features of claim 1.

According to the invention can thus be corrected on this second pivot bearing, the altitude of the wing and adapted to the altitude of the other wings.

When fitting according to the invention, the second pivot bearing, which forms the axis of rotation of the wing, guided on a rail displaceable. In addition, this axis of rotation is always in the same plane, which has a distance to the plane of the first pivot bearing. Another one Feature provides that the second pivot bearing in the plane of the sash, however, is laterally adjacent to the vertical frame spar. This ensures that the casement is pivoted exclusively into the interior and no part of the casement goes out through the fixed frame to the outside.

Advantageously, the axis of rotation is behind the wing flap of the adjacent wing. As a result, the advantage is achieved that the axis of rotation is covered by the wing flap and thus is not visible. Only when swinging, i. Turning the middle wing, the axis of rotation emerges behind the wing rollover, by the second pivot bearing in the rail is displaced away from the adjacent wing.

A preferred embodiment provides that the second pivot bearing is provided on a displaceably guided on the rail second carriage. This second carriage, which consists for example of zinc die-casting, is displaceable in the running rail, which consists for example of brass, out. The tribological properties are chosen so that the carriage can be moved easily. By the Design of the two steel handlebars high forces can be transmitted.

A secure and play-free mounting of the carriage is ensured by the fact that the rail has a substantially U-shaped profile and the second carriage is guided on both sides. The double-sided leadership has the advantage that even improper opening, gusts or the like. Do not cause damage to the fitting, especially the rail.

With preference, the second carriage has a substantially downwardly open U-shaped profile. This provides the possibility that the second pivot bearing can be riveted to the second carriage without the rivet head facing down, i.e., the rivet head. protruding in the direction of the rail, has a disturbing effect. Furthermore, the sliding friction surfaces are reduced by the inventive design of the carriage.

A preferred embodiment provides that the second bearing has a second bearing journal, which carries a thread over a part of its circumference, onto which a press-fit sleeve, which is connected to the second link, is screwed. About this camp, the height of the wing can be adjusted. This is preferably adjustable Bearing designed as a lower bearing, wherein the upper bearing is designed in the form of a sliding bearing, which has a cylindrical pin on which the corresponding press-in sleeve is axially movable. In this way, thermal expansion can be easily compensated. This cylindrical bearing pin is rigidly riveted to the carriage, whereas the threaded bearing pin is rotatably fixed to the carriage.

In a further development it is provided that the third pivot bearing is arranged at a distance from the center line of the first and / or the second link in this. In this case, both the third bearing and the second bearing are offset from the first pivot bearing to the interior side.

With preference, the first rotary bearing has an eccentrically arranged first bearing journal and is rotatably mounted. Through this first eccentric bearing pin, the position of the pivot bearing can be changed transversely to the longitudinal direction of the rail slightly and thereby the contact pressure of the wing are set to the fixed frame. In this way, differences that are equalized in the thickness of the sealing rubber or the position of the wing can be adjusted when using different sealing rubbers.

In a further development of the invention, it is provided that the first pivot bearing is provided on a first slide. As a result, the possibility is created to store the first slide adjustable in the rail, whereby the position of the axis of rotation of the wing in the longitudinal direction of the rail can be changed. To adjust the first carriage an eccentric pin is provided. The use of an eccentric pin as an adjusting member has the significant advantage that the setting steplessly and by simple means, e.g. by means of a screwdriver, a hexagonal wrench or the like., Can be done.

Optimal movement conditions when pivoting the wing and removing its axis of rotation from the adjacent wing, are achieved in that the aspect ratio of the effective length of the second link to the first link between 40% and 70%, in particular between 50% and 60%, preferably 55% , As a result, especially a collision of the adjacent frame, in particular the flashovers, and a displacement of a part of the turned wing is avoided to the outside.

Figures 1 and 2 show a generally designated 10 window, which has a fixed frame 12, on which three wings 14, 16 and 18 are rotatably mounted. In addition, the wing 14 is tiltable about a horizontal axis. The wings 14 and 18 are provided on their casement 20 and 22 with handles 24 with which the wings 14 and 18 can be locked or brought into the rotational or tilted position. The wing 18 adjacent edge of the sash frame 26 of the wing 16 is overlapped by the wing flap of the wing 18, so that the wing 16 can only be opened when the wing 18 is also open. This position of the two wings 16 and 18 is shown in Figure 2, in which the two wings 16 and 18 are rotated about vertical axes.

FIG. 3 shows the section III - III according to FIG. 1, from which it can be seen that the casement 26 is provided with a side facing away from the interior of the room 28 Wing rollover 30 of the sash 20 is partially overlapped. Behind this wing flap 30 is concealed the vertical axis of rotation 32 of the wing frame 26. On the outer side 34 of the wing frame 20 of the wing 14 is partially overlapped by a wing flap 36 of the sash 26.

Figure 4 shows the two wings 14 and 16, with the wing 16 partially open, i. was rotated about the rotation axis 32. It can be seen that the axis of rotation 32 has been slightly removed from the wing 14, which will be explained in more detail below.

The axis of rotation 32 is provided on a fitting 38, the lower fitting part is shown in Figures 5 and 6. This fitting 38 has a rail 40, which consists of brass. The rail 40 has a U-shaped profile, the two legs 42 has drawn inwardly free ends. In this way, a carriage 44 is held captive and free of play such that it can be moved in the rail 40. On the carriage 44, a second link 48 is rotatably supported by means of a second pivot bearing 46, said second link 48 extends parallel to the plane of the sash frame 26 of the wing 16, as shown in Figures 3 and 4 can be seen. In the rail 40 is another Carriage 50 (first carriage) mounted on which a first pivot bearing 52, a first link 54 is pivotally mounted. The first link 54 and the second link 48 are coupled to each other via a third pivot bearing 56, which is provided at the free end of the first link 54 and engages approximately in the middle of the second link 48, but at a distance a to the center line 58 of the second Handlebar is arranged. The third pivot bearing 56 has a distance b from the center line 60 of the first link 54. Preferably, the distances a and b are equal. It is also apparent from FIG. 6 that the second pivot bearing 46, which forms the axis of rotation 32 of the middle wing 16, is also arranged at a distance c from the center line 58 of the second link 48.

In the figures 5 and 6 is still shown that the rail 40 has a stop 60 on which the carriage 44 abuts when the wing 16 assumes its maximum open rotational position. This stopper 60 limits the opening movement. Further, it can be seen that when opening the wing 16, ie when swinging the two links 48 and 54, as shown in Figure 6, the carriage 44 is moved from its rest position, which is shown in Figure 5, in the direction of the stopper 60 , By the displacement of the carriage 44 in the Rail 40 is the axis of rotation 32 displaced away from the wing 14, whereby a collision of the two wing frame 20 and 26, in particular of the wing flashover 30, with the interior of the room 28 facing part of the sash 26, is avoided.

Figures 7 and 8 show in enlarged scale sections of the lower and the upper part of the fitting 38, in particular the lower second pivot bearing 46 and the upper second pivot bearing 62. These pivot bearings 46 and 62 are riveted to the respective carriage 44 at 64, wherein the rivet head is in a recess 66 space, which is formed by the fact that the carriage 44 is U-shaped and rests only with its free, downwardly projecting leg ends on the sliding surface of the rail 40. In the second pivot bearing 46 of the lower part of the fitting 38, a part of the circumference is provided with a thread 68, on which a press-fit sleeve 70 is seated, which has a corresponding internal thread. This press-in sleeve 70 is pressed into a corresponding opening of the second link 48. By turning the second pivot bearing 46, for example with a hex key, the press-in sleeve 70 is adjusted in height and thereby changes the height of the wing 16 with the second link 48.

The illustrated in Figure 7 upper second pivot bearing 62 has a smooth cylindrical body on which a press-in sleeve 70 'is axially displaceably guided. This press-in sleeve 70 'is tracked during adjustment of the lower second pivot bearing 46 and it can also be compensated for thermal expansion. In the figures 7 and 8 also closing plates 72 are shown, which are fixed together with the rail 40 on the fixed frame.

9 shows the lower part of the fitting 38 in a perspective view, wherein clearly the adjustment possibilities of the second pivot bearing 46, the first pivot bearing 52 and the first carriage 50 by means of an eccentric pin 74, can be seen. The adjustment is preferably carried out by means of a hexagonal wrench. The eccentric pin 74 is, as shown in Figure 6, in a slot 76 which extends transversely to the longitudinal axis of the rail 40, arranged in the carriage 50. The eccentric to the head of the eccentric 74 bearing is located in the rail 40. If now the eccentric pin 74 is rotated, then the carriage 50 is displaced in the direction of the double arrow 78.

Also, the first pivot bearing 52 is formed as an eccentric pin, which is clearly shown in Figure 5. By turning the first pivot bearing 52 is an adjustment the bearing axis 80 in the direction of the double arrow 82 causes. In this way, the closing pressure of the wing 16 can be adjusted.

From Figures 6 and 9 is still visible; that the effective length of the second link 48 to the first link 54, i. the distance of the pivot bearings 46 and 56 to the distance of the pivot bearings 56 and 52 a ratio of 55: 100, i. 55%.
