Abstract

The fitting assembly (1) for window or door leafs has a casement (3) and a fixed frame (2), and two crossing over links interconnected by a rotatable slide connection, whereby one of the links forms an adjusting arm for the casement and the other link forms a control arm for the adjusting arm. For the connecting of the control arm and casement one end of the control arm is rotatably connected to an intermediate link via a rotatable bearing, and the intermediate link is rotatably connected to the casement via a further rotatable bearing (22).

Description

The present invention relates to a fitting arrangement for wings of windows, doors or the like with a sash and a fixed frame, which is arranged concealed between the sash and the fixed frame, wherein the sash has a sash overlap, which rests on the fixed frame with the sash closed and the two X-shear forming intersecting links interconnected by a pivotal connection, one of the links forming a wing arm extension arm and the other link forming a control arm for the extension arm, each rotatable one end of the extension arm and the control arm is mounted on the fixed frame, and the other end of the extension arm is rotatably supported by a wing pivot bearing on the casement, whereby an axis of rotation for the wing is defined.

Such completely concealed hardware assemblies require that the overlying blade be able to disengage with the flap overlying the fixed frame when opened, without undue compression of a seal disposed between the blade and the fixed frame, and a collision between the blade Wing flashover and the fixed frame when opening the window is avoided.

It is known to arrange the rotary fittings resting on adjacent wings, in order to avoid a corresponding collision or a crushing destruction of the seal and the flashover. However, such a solution is undesirable for optical reasons resting fittings affect the overall appearance of the window sash assembly.

Furthermore, it is known to form the wing frame without wing flap when fitting fitting arrangements. However, this solution is not desirable because in such a solution, both with the window closed and with the window open a gap between the outer edge of the sash and the adjacent inner edge of the fixed frame is visible, which also affects the visual impression of the arrangement.

From DE 102 05 009 C2, a fitting arrangement of the aforementioned type is known, in which the wing pivot bearing is automatically displaced in a direction perpendicular to the main plane of the fixed window frame by the X-scissors used when pivoting open the wing. It is thereby achieved that, when the wing is opened, the wing flap is automatically lifted off the fixed frame, so that a collision between the wing flap and the fixed frame is prevented. In order to enable the function of the X-scissors thereby, the end facing away from the fixed frame end of the control arm is not only rotatable, but also in parallel to the wing frame slidably articulated thereto.

Since the extension arm and the control arm in the fitting arrangement according to DE 102 05 009 C2 have a relatively short length to each form a short lever arm and connected to achieve improved stability, a swivel-controlled shear drive for the wing is additionally provided in this fitting arrangement , by means of which the wing is displaceable relative to the vane pivot bearing. The thrust drive is required because of the small length of the arms the X-scissors wing vane is issued only relatively little perpendicular to the main plane of the fixed frame, so that at a complete opening of the wing of the wing flap would ultimately collide with the fixed frame. Such a collision is prevented by a corresponding longitudinal displacement of the wing by means of the thrust drive.

A disadvantage of the fitting arrangement according to DE 102 05 009 C2 is that, when the sash is completely open, the sash overlap protrudes far laterally into the stationary frame. It is thus necessary in this fitting arrangement to provide a large clearance between the outer edge of the sash and the adjacent wall soffit to prevent collision of the sash when opening with the wall reveal.

It is an object of the present invention, a fitting arrangement of the type mentioned in such a way that the free space between the sash and the soffit can be minimized, while a collision of the sash with the fixed frame and a compression between the wing flap and the fixed frame existing seal when opening the wing is prevented. Furthermore, the fitting arrangement should be sufficiently stable and be visible in both the closed and in the open state of the wing no discernible in plan view vertical gap between the outer edge of the wing and the inner edge of the fixed frame.

This object is achieved on the basis of a fitting arrangement of the type mentioned in that for the connection of control arm and sash over the other end of the control arm a pivot bearing with an intermediate link is rotatably connected and that the intermediate link is rotatably connected via a further pivot bearing with the casement.

By the invention it is achieved that the wing pivot bearing when opening the wing not only in a direction perpendicular to the main plane of the fixed frame, but also moves parallel to the frame center, so that the free space between the sash and the soffit when opening the Wing remains essentially constant. The fixed frame can therefore be used with a minimum clearance in the wall, without causing a collision between the wing flap and the soffit when opening the wing.

Furthermore, it is achieved by the invention that the extension arm of the X-scissors over known embodiments can be formed shortened, whereby the stability of the fitting assembly is increased. At the same time, the intermediate link ensures that when the sash is fully open, the control arm is pivoted by a significantly smaller opening angle relative to the fixed frame than the sash, whereby an optimal exhibition of the position of the sash pivot bearing is achieved.

According to a further advantageous embodiment of the invention, the intermediate link is rotatably connected at one of its ends to the control arm and / or at its other end to the casement. In this way, a particularly compact construction of the fitting arrangement according to the invention is achieved.

According to a further advantageous embodiment of the invention, the intermediate link is immovably connected to the control arm and / or the sash. Preferably, the control arm are immovably connected to the fixed frame and / or the extension arm immovably connected to the sash and / or with the fixed frame. Thus, all four free ends of the X-scissors and the two ends of the intermediate link are preferably mounted exclusively on pure pivot bearings, so that additional sliding connections or rotary sliding connections are not required. The fitting arrangement according to the invention is thus more stable and can be manufactured more cost-effective than corresponding fitting arrangements with combined rotary sliding bearings.

According to a further preferred embodiment of the invention, the intermediate link is at least temporarily arranged substantially parallel to the extension arm during the rotational opening of the wing. Preferably, the intermediate link is arranged essentially parallel to the extension arm during the entire opening process. For the purposes of the present invention, a deviation of at most approximately 30 degrees, in particular of at most approximately 20 degrees, preferably of approximately approximately 15 degrees, is advantageously permissible for the parallel arrangement. By means of this quasi-parallel arrangement of intermediate link and extension arm, the already mentioned optimum geometry of the fitting arrangement according to the invention is achieved, by means of which the wing pivot bearing is optimally positioned, in particular even when the wing is completely open.

According to a further preferred embodiment of the invention, the intermediate link and the extension arm are arranged overlapping each other with the wing closed. As a result, a very small construction of the fitting arrangement according to the invention is achieved, so that no additional milling on the wing or on the fixed frame are required.

Preferably, an opening limitation is provided between the fixed frame and the control arm. This opening limit can be formed, for example, by at least two hingedly interconnected, forming a stay scissors limiting arms, one of which is rotatably connected to the fixed frame and the other with the control arm. However, it is also any other suitable opening limitation used, for example, the opening limit can also be formed by a one-piece link, which is articulated, for example, on the fixed frame. Likewise, the other end of the handlebar may be attached directly to the casement, which is also conceivable in a multi-part design of the opening limit.

Further advantageous embodiments are specified in the subclaims.

Fig. 1 shows a fitting assembly 1, which is fixed to a fixed frame 2, in particular screwed to this. The fitting assembly 1 is arranged so that it comes to lie completely hidden in the fold between the fixed frame 2 and a cooperating with the fixed frame 2 sash 3.

The sash frame 3 is pivotable about a sash pivot 4 relative to the fixed frame 2, which forms a plane of rotation for the sash frame 3 perpendicular to the plane of the drawing in FIG. 1 and is formed as part of the fitting arrangement 1.

The sash 3 has a sash overlap 5, at its outer surface facing the fixed frame 2, a seal 6 is arranged, which abuts in the closed position of the window facing the sash 3 towards the outside of the fixed frame 2 in the closed position shown in Fig. 1 and the closed This seals the window.

As can be seen in particular from FIGS. 3 to 8, the fitting arrangement 1 comprises a frame plate 7, which is screwed by means of screws 8 to the fixed frame 2.

On the frame plate 7, two pivot bearings 9, 10 are provided, via the two arms of an X-scissors 11 are rotatably connected to the frame plate 7 and thus to the fixed frame 2. The hinged to the pivot bearing 9 handlebars of the X-scissors 11 forms a stay 12 for the sash frame 3, while hinged to the pivot bearing 10 arm of the X-scissors 11 forms a control arm 13 for the stay 12.

While the pivot bearing 10 is formed by a bearing bush formed in the control arm 13 and formed on the frame plate 7, engaging in the bearing bushing guide pin 14, the pivot bearing 9 comprises a Aushängezapfen 15 with bayonet lock, via which the connection between the extension arm 12 and the frame plate 7 can be secured. At the same time a simple removal of the X-scissors 11 of the frame plate 7 is possible due to the bayonet connection.

In the extension arm 12, a longitudinal guide 16 is formed, in which a formed on the control arm 13 guide pin 17 engages, whereby the X-scissors 11 is formed.

The end facing away from the pivot bearing 9 of the extension arm 12 is connected via the wing pivot bearing 4 with a wing-side corner bearing bracket 18 to which the casement 3 is fixed in a conventional manner. For this purpose, the Ecklagerwinkel has 18 holes 19 for screws with which the sash 3 can be bolted to the corner bearing bracket 18.

At the end remote from the pivot bearing 10 of the control arm 13, a further pivot bearing 20 is provided, via which an intermediate link 21 is rotatably connected to the control arm 13. The remote from the pivot bearing 20 end of the intermediate link 21 is connected via a further pivot bearing 22 with the corner bearing bracket 18 and thus with the sash 3.

As can be seen from the figures, the intermediate link 21 extends with slight deviations (less than 20 degrees) in all positions of the sash 3 shown parallel to the extension arm 12, so that the intermediate link 21 forms a spacer element between the control arm 13 and the sash 3, whereby Especially in the fully open position of the wing of the sash 3 includes a larger opening angle with the fixed frame 2 as the control arm thirteenth

On the control arm 13 is adjacent to the pivot bearing 20, a further pivot bearing 23 is provided, on which an opening boundary 24 is hinged, which by two hinged interconnected, a Ausstellschere forming limiting arms 25, 26 comprises. While the limiting arms 25, 26 are connected to one another via a further rotary bearing 27, the end of the limiting arm 26 facing away from the rotary bearing 27 is ultimately also rotatably connected to the window frame plate 7 via a further rotary bearing 28. The pivot bearing 28 may for example comprise a latchable pin, so that the opening limit 24 can be easily removed from the frame plate 7.

At the opposite end of the rotary bearing 28 of the Begrenzungsarms 26 designed as a fold stop 29 is provided which comes at fully open wing (see Fig. 7) formed on a trained as a groove 30 counter-stop on the limiting arm 25 to rest. This prevents the limiting arms 25, 26 from being parallel to one another when the window is completely open, which could cause jamming when the window is closed. The fact that the stop 29 already comes to rest in the groove 30 before reaching the full extent of the opening limit 24, ensures that the closing arms 25, 26 buckle in a defined direction according to an arrow 31 when closing the wing.

Hereinafter, the function of the inventively embodied fitting assembly will be described with reference to Figs. 1 to 8 in detail.

When the wing is fully closed, the fitting assembly 1 is in the position shown in Figs. 1 and 2, where it is completely hidden within the fold between the fixed frame 2 and the sash 3. The wing-pivot bearing 4 is in the position shown in Fig. 1, so that a simple rotation opening would lead to the rotation axis defined by the vane rotary bearing 4 to a compression of the seal 6 and to a collision of the wing flap 5 with the fixed frame 2.

Due to the embodiment of the invention, when pivoting open the wing according to FIGS. 3 and 4 of the connected via the pivot bearing 22 with the wing arm 3 intermediate link 21 also moved out of the main plane of the fixed frame 2, whereby also connected via the rotation axis 22 with the intermediate link 21 Control arm 13 is pivoted about the axis of rotation 10 out of this main plane.

The pivoting of the control arm 13 is transmitted via the guide pin 17 on the extension arm 12, so that it is also pivoted about its axis of rotation 9 from the main plane of the fixed frame 2 out, the guide pin 17 is displaced in the longitudinal guide 16.

By the pivoting of the extension arm 12 and the wing pivot bearing 4 is pivoted out of the main plane of the fixed frame 2, wherein the wing pivot bearing 4 relative to the position shown in Fig. 1 with the window fully closed both a displacement perpendicular to the main plane of the fixed frame. 2 as well as in parallel towards the frame center experiences, as it is seen from Figs. 3, 5 and 7 can be seen.

In a further pivoting of the wing in its fully open position, as shown in FIGS. 7 and 8, there is a further displacement of the vane pivot 4, so that at no time occurs the wing flap 5 with the fixed frame 2 into contact , At the same time, the displacement becomes parallel to the fixed one Frame 2 achieves that in the closed position shown in FIG. 1 existing free dimension 32 between the outer edge of the sash flap 5 and a soffit, not shown remains substantially constant during the entire opening operation of the wing.

The parallel displacement of the vane pivot 4 is dimensioned so that at the same time at no time in a plan view of the sash 3 from the front, a gap between the sash 3 and the fixed frame 2 is visible because in all positions a slight overlap between the wing flap 5 and the fixed frame 2 is present.

The inventive fitting arrangement thus a compression of the seal 6 and a collision of the wing flap 5 with the fixed frame 2 is prevented by an automatic lifting of the sash frame 3 from the fixed frame 2 when opening. At the same time it is ensured that the clearance between the wing flap 5 and an adjacent reveal in all positions of the sash 3 is maintained without a disturbing gap in the plan view of the wing between the sash 3 and the fixed frame 2 would be visible. With the fitting arrangement according to the invention thus the installation of the fixed frame 2 with minimal clearance for soffit is possible.

While the invention has been described with reference to the embodiment of a rotary window, the fitting arrangement according to the invention is basically also in a turn-tilt window and a corresponding door or the like used.
