Description

The invention relates to a fitting, in particular a corner bearing or a Ausstellschere, for coupling a wing of a window or a door with a frame, wherein the fitting is designed such that it limits the opening path, in particular the opening angle of the window or the door.

A generic fitting is from the DE 39 12 387 known. The corner bearing disclosed in this document is arranged concealed between the glare and the sash of a window or door and is particularly suitable for turn / tilt or tilt-swivel wings. The fitting consists of several articulated levers, which perform the pivoting movement, carry the weight of the sash and specify an opening limit. The fitting is fastened both in the rigid frame and in the movable wing.

The known solutions have proven themselves, but it is problematic that sometimes damage to the fitting or on the frame parts despite sturdy construction.

The solution to this problem is the object of the invention.

This object is solved by the subject matter of claim 1.

Thereafter, the fitting has a brake for reducing the speed of the opening movement of the wing, in particular of the Endlge at least over a section - preferably a last section - the opening path on.

The invention prevents the opening movement of the wing is stopped unbraked in the maximum open position, so that no longer as in the prior art, the entire kinetic energy is introduced at once in the fitting part and in the frame of the window or the door, which due to could occur due to the abrupt deceleration of the wing movement occurring considerable forces damage and destruction of both the fitting part and the frame construction. All these effects the invention counteracts in a simple way.

Due to the brake, the speed of the opening movement of the wing in the area is already braked before reaching the maximum open position or end position. As a result, the remaining momentum is minimized immediately before reaching the end position, so that damage to the fitting and frame construction can be avoided.

The brake is preferably designed to realize a safe function as a friction brake.

Particularly preferably, the brake is designed in a compact and inexpensive to implement variant with good braking effect as a brake clip, which is designed such that it acts on the opening of the wing over a predetermined opening angle of time braked on a brake body.

Preferably, the brake is configured such that the braking force on the brake body increases with increasing opening angle of the wing, so that the wing is braked increasingly strong, which guarantees a particularly safe function of the brake.

It lends itself to the implementation of a compact design on, when the brake body is designed as a bolt. Other types of brake body are conceivable.

Further preferably, both the friction brake, in particular the brake clip, and the brake body are integrated directly into the fitting, so that no additional elements must be attached to the wing and the frame.

It is expedient if the brake clip has a base body, which is at least partially provided with a friction lining, wherein the base body of a first material and the friction lining of a second material with a relative to the first material higher coefficient of friction. The brake should on the one hand have a good coefficient of friction for braking the wing and on the other hand a sufficient spring force to hold the wing in its open position.

The arranged on the fitting brake can be realized in a compact, small size, so that the fitting can continue to be located in the rebate area between the sash and frame.

In addition, the opening angle of the wing is preferably specified or limited directly by the brake.

According to an advantageous variant, the brake is designed such that it holds the wing - preferably latching - in the open position, so that an effective additional assurance is provided. In this way it is prevented that the wing accidentally unintentionally -. by draft - closes.

The fitting part according to the invention is preferably designed as a bearing for a turn-tilt window, ie for pivoting a wing about two different axes of rotation or in two directions.

Further advantageous embodiments can be found in the remaining subclaims.

Figure 1 shows a designed as a corner bearing 1 for a window fitting, which is designed to couple a wing with a frame. The fittings according to the invention serve at least to limit the opening movement of the wing relative to the frame. Optionally, they also realize one or both of the functions of swivel and / or tilt bearings between the sash and the frame.

The corner bearing shown in Fig. 1 serves so far on the one hand to couple a (not shown here) wing with a frame rotatably. In addition, it also serves for the pivotable Lagering the wing in the frame.

Fig. 1 shows the corner bearing 1 in the installed position of a closed wing.

Towards the wing frame, the corner bearing on a wing rail 2, which can be fixed with the aid of sliding blocks 3 and 4 in a groove of the sash. At one end of the wing rail 2 to the wing rail 2 angularly aligned stop 5 is arranged, which can also be attached to the casement. In the illustrated embodiment, the stopper 5 is inserted into grooves of the sash (not shown here).

The angular arrangement of the wing rail 2 and the stop 5 allows an arrangement of the corner bearing at a corner of the sash. However, it is also conceivable, e.g. at a swing wing to arrange such a fitting between two straight running profiles (wings and frame) (not shown here).

Opposite the wing rail 2 is - partially hidden in the representation - a frame rail 6 is arranged.

The frame rail 6 has an end angularly arranged stop 7 for positioning and bearing alignment.

The frame rail 6 and the stopper 7 are also arranged in the corner of a window frame (frame). Thus, the position of the wing is defined self-teaching.

The space between the wing rail 2 and the frame rail 6 is referred to as a rebate or fitting chamber.

Since the fitting part according to the invention is arranged completely in the fitting space, it is a concealed fitting or a concealed corner bearing.

Between the wing rail 2 and the frame rail 6 levers 8 and 9 are arranged. These levers 8 and 9 are articulated via bolts with the wing rail 2, the frame rail 6 and possibly interconnected.

At the corner bearing a brake is formed according to the invention, which brakes the wing on its last stretch before reaching the maximum open position.

This brake is designed as a friction brake. It has here in a particularly advantageous embodiment, the shape of a brake bracket 11 which is adapted to decelerate the movement of a brake element, here the movement of a bolt 10 on the wing in the manner of a brake calliper.

The bolt 10 is movable relative to the brake bracket 11 and runs when opening the wing in the last portion of the opening movement in the brake bracket 11, which exerts a directed substantially normal to the movement of the bolt 10 force on this.

The bolt 10 is here advantageously arranged directly on the wing rail 2 and fixed thereto.

The bolt 10 serves as a brake body. This element could also be formed in another form, e.g. as an elongated footbridge.

The brake clip 11 is formed corresponding to the bolt 10 and may also take on different shapes and configurations.

The brake clip 11 is also guided relative to the wing rail 2 and transversely movable. It is connected via a bolt 12 fixed to the lever 8, which passes through a hole in the wing rail 2.

When opening the wing, the brake clip 11, which is coupled to the lever 8 and rests movably on the guide rail 2, moved relative to the guide rail 2 on the same.

The structural design of the brake clip 11 is chosen so that it can be moved to save space within the groove for the sliding blocks 3 and 4 of the casement profile.

The brake is configured such that it does not act over part of the opening movement of the wing until the bolt 10 enters the brake clip 10.

In the last section or angular range of the opening movement, the movement of the bolt 10 and thus of the wing is then decelerated until the bolt 10 comes to a stop in the base of the brake clip 11, so that the brake clip also realizes a device for opening travel limitation.

Figure 2 shows the fitting 1 according to the invention in a flared position corresponding to the opened wing of the window or the door. Here is a stop position to detect approximately 90 ° opening angle. Of course, this angle can also be chosen in other sizes.

In the open position of the fitting or the wing is easy to see that the bolt 12 is moved longitudinally movable in the groove 13 of the wing rail 2 and thereby the Brake clamp 11 has moved in the direction of the bolt 10. The brake clip 11 is thereby moved with the slot 14 on the bolt 10 to an end stop.

• Die Bremsspange 11 und der Bolzen 10 erzeugen energieverzehrende Reibkräfte;
• Die Schenkel 17, 18 der Bremsspange 11 werden zur Seite gedrückt, wodurch es zu Verformungskräften kommt;
• Die seitlich abstehenden Schenkel 17, 18 der Bremsspange 11 werden innerhalb der Nut des Flügelrahmens (hier nicht dargestellt) in ihrer Breite begrenzt, wodurch es zu energieverzehrende Reibkräfte zwischen Flügelprofil und Bremse kommt.
• Es kommt zu einer Materialverformung (Kompression) der Schenkel 17, 18, da diese mit zunehmendem Einfahren der Bremse auf den Bolzen 10 nicht weiter zur Seite gedrückt werden können.
• Schließlich kommt es zu einem Verrasten am Ende des Langloches in der Bremsspange 11, wodurch der Öffnungsweg begrenzt wird. Hieraus ergibt sich eine progressive Bremswirkung.

The slot 14 of the brake clip 11 is dimensioned such that the slot width is smaller than the diameter of the bolt 10. This results in the following (successive) effects:

• The brake clip 11 and the bolt 10 generate energy-consuming frictional forces;
• The legs 17, 18 of the brake clip 11 are pushed to the side, resulting in deformation forces;
• The laterally projecting legs 17, 18 of the brake clip 11 are limited within the groove of the sash (not shown here) in its width, resulting in energy-consuming frictional forces between the sash profile and the brake.
• There is a deformation of the material (compression) of the legs 17, 18, since they can not be pushed further to the side with increasing retraction of the brake on the bolt 10.
• Finally, it comes to a latching at the end of the slot in the brake clip 11, whereby the opening travel is limited. This results in a progressive braking effect.

By selecting different dimensions and by selecting different materials, the braking effect can be adjusted.

In the end position of the open wing, the bolt 10 is located in an end region of the slot in which the diameter is increased. As a result, a restraining effect is achieved, which prevents the wing, to move independently (eg by wind draft) back into the "closed" position. This fitting 1 according to the invention therefore implements an additional securing feature, ie, when closing the wing, a certain minimum force must first be applied in order to be able to move the bolt 10 relative to the oblong hole 14 in order to close the wing.

Figure 3 shows separately in an isometric view of the brake clip 11, which consists of a base body 15 on which the actual friction lining 16 is arranged.

The base body 15 has for attaching to the lever 8 preferably a slot 19 in order to perform a slight pivoting movement in the tilted position of the wing can. The brake 11 is fastened in the slot with a bolt in such a way that the brake 11 is fastened on a lever 8 with a base 20 which engages through the oblong hole 13 of the wing rail 2.

The actual friction lining 16, like the base body 15 has two legs 17 and 18, between which a kind of slot or a slot 14 is formed.

This outwardly V-shaped open slot 14 is laterally limited to the legs of friction or braking surfaces, which have different sizes depending on the dimensioning and choice of material brake or friction.

Opposite to the V-shaped opening of the elongated hole is a stop opening 21 which has approximately the diameter of the bolt 10.

In its end position ("open" position), the bolt engages, so that the legs spread apart during the braking movement 17, 18 spring back and surround the bolt, so that it can be released again only after exceeding a limit force from the open position.

The legs 17 and 18 of the brake clip have outwardly surfaces 22 which serve as boundary surfaces of the spreading movement when entering the bolt 10 by coming to rest on the inner sides of the Flügelprofilnut. In this case, they also act as further friction or braking surfaces when they are moved within the Flügelprofilnut.

Particularly preferably, the brake clip 11 from two different elements - the clasp-like base body 15 and the likewise clasp-like friction lining 16 - composed, which consist of different materials.

Thus, the base body 15 is preferably made of a relatively strong plastic, while the friction lining 16 is preferably made of a softer, compressible plastic, which has a relatively high coefficient of friction.

Figure 4 shows that the base body 15 and the friction lining 16 are preferably not only non-positively but also positively connected to each other. Thus, the integrally formed legs 23 of the body 15 are provided with lateral recesses 24, in which the friction lining 16 engages, which produces the positive connection between the base body 15 and the friction lining 16.

This is advantageous since, when the wing is closed, ie when the bolt 12 is moved out of the oblong hole 14, tensile forces are applied to the friction lining 16 in relation to the base body 15. In addition, the deformation force of the legs is increased overall.

Preferably, the base body 15 is encapsulated with the friction lining 16.

In summary, among other things, the following functions are realized in the illustrated embodiment: fitting as concealed corner bearing with opening limiting function; Fittings with additional security (wing is kept in "open"position); Fitting with brake for the opening movement; Gradual braking effect -progressive-; Brake, consisting of two different materials (coefficient of friction, spring force) and fitting, designed for turn-tilt elements (2-axis pivot point).
