Description

The 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 he the opening way, in particular the opening angle, the window or the door limited.

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 problematic, however, is that, despite its robust construction occasionally on the fitting or on the frame parts damage occur.

The Remedy of this problem is the object of the invention.

These The object is solved by the subject matter of claim 1.

After that The fitting has a brake to reduce the speed the opening movement of the grand piano, in particular of the Endlge at least over a section - preferably a last section - the opening way, on.

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

By the brake will increase the speed of the opening movement of the wing Range already before reaching the maximum opening position or end position braked. As a result, the remaining kinetic energy is direct minimized before reaching the end position, causing damage to be avoided on fitting and frame construction.

The Brake is preferably for realizing a safe function designed as a friction brake.

Especially Preferably, the brake is in a compact and inexpensive to implement variant designed with good braking effect as a brake clip, which is such is designed to open when you open the Wing over one predetermined opening angle Braking on a brake body acts.

Preferably the brake is designed such that the braking force on the Brakes with increasing opening angle of the grand piano increases, so the wing increasingly slowed down, which is a particularly safe function the brake is guaranteed.

there it is suitable for implementing a compact design, when the brake body is designed as a bolt. Other types of brake body are conceivable.

Especially Further, both the friction brake, in particular the Brake bar, as well as the brake body integrated directly into the fitting, so that no wings on the wing and on the frame additional Elements must be attached.

there it is useful if the brake clip a body has, at least partially provided with a friction lining is, being the main body of a first material and the friction lining of a second material consist with a relative to the first material higher coefficient of friction. The Brake should on the one hand a good coefficient of friction for the braking of the wing and on the other hand a sufficient Have spring force to the wing to hold in his open position.

The Brake mounted on the fitting can be made smaller, smaller Realize size, so that the fitting continues in the rebate area between the wing and Frame can be arranged.

In addition will preferably also directly predetermined by the brake, the opening angle of the wing or limited.

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 itself unintentionally - eg by draft - closes.

The fitting part according to the invention is preferably as a warehouse for a turn-tilt window, So for a panning of a grand piano designed around two different axes of rotation or in two directions.

Further advantageous embodiments are the remaining dependent claims remove.

following The invention is based on an embodiment with reference closer to the figure explains wherein also further advantages of the invention become clear. It shows:

1 a perspective view of a corner bearing according to the invention in a closed position;

2 a perspective view of a corner bearing according to the invention in an open position;

3 a perspective view of the brake of the corner bearing 1 ; and

4 an element of the brake 3 ,

1 shows you as a corner warehouse 1 formed for a window fitting, which is adapted 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.

This in 1 Corner bearing shown serves 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.

1 shows the corner warehouse 1 in the installation position of a closed wing.

To the sash, the corner bearing has a wing rail 2 on, with the help of sliding blocks 3 and 4 can be mounted in a groove of the sash. At one end of the wing rail 2 is one to the wing rail 2 Angled stop 5 arranged, which can also be attached to the casement. In the illustrated embodiment, the stop 5 inserted in grooves of the sash (not shown here).

The angled arrangement of the wing rail 2 and the stop 5 allows an arrangement of the corner bearing at a corner of the sash. It is also conceivable, for example, in a swinging 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 arranged.

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

The frame rail 6 and the stop 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 called a rebate or fitting chamber.

There the fitting according to the invention completely is arranged in the fitting room, it is a hidden lying fitting or a concealed corner bearing.

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

At the corner bearing is a brake according to the invention formed the wing on his last stretch before reaching the maximum opening position decelerating.

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

The bolt 10 is relative to the brake clip 11 movable and runs when opening the wing in the last section of the opening movement in the brake clip 11 one which is essentially normal to the movement of the bolt 10 directed force exerts on this.

The bolt 10 Here is advantageously directly on the wing rail 2 arranged and fixed to this.

The bolt 10 serves as a brake body. This element could also be formed in a different form be, for example, as an elongated footbridge.

The brake clip 11 is corresponding to the bolt 10 trained and may also take different forms and configurations.

The brake clip 11 is also relative to the wing rail 2 and moved transversely. She is over a bolt 12 firmly with the lever 8th connected, which has a bore of the wing rail 2 interspersed.

When opening the wing, the brake clip 11 that with the lever 8th is coupled and on the guide rail 2 movable rests, relative to the guide rail 2 proceed on the same.

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

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

On the last section or angular range of the opening movement is then the movement of the bolt 10 and thus the wing slowed down until the bolt 10 in the bottom of the brake clip 11 comes to a halt, so that the brake clip also realizes a device for Öffnungswegbegrenzung.

2 shows the fitting according to the invention 1 in a raised position corresponding to the open wing of the window or 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 longitudinally movable in the groove 13 the wing rail 2 method is and thereby the brake clip 11 in the direction of the bolt 10 has moved. The brake clip 11 is doing with the slot 14 on the bolt 10 moved 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 the brake clip 11 is dimensioned such that the slot width is smaller than the diameter of the bolt 10 , This leads to the following (consecutive) effects:

• - The brake clip 11 and the bolt 10 generate energy-consuming friction forces;
• - The thigh 17 . 18 the brake clip 11 are pushed aside, causing deformation forces;
• - The laterally projecting legs 17 . 18 the brake clip 11 are within the groove of the sash (not shown here) limited in width, resulting in energy-consuming frictional forces between the sash and the brake.
• - There is a deformation of the material (compression) of the legs 17 . 18 because these with increasing retraction of the brake on the bolt 10 can not be pushed further to the side.
• - 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 Selection of different sizing and selection of different ones Materials, the braking effect can be adjusted.

In the final position of the opened wing there is a bolt 10 in an end region of the slot in which the diameter is increased. As a result, a latching effect is achieved, which prevents the wing from moving independently (eg by wind draft) back into the "closed" position 1 So realized also an additional assurance, ie, when closing the wing must first be applied a certain minimum force to the bolt 10 relative to the slot 14 to be able to move to close the wing.

3 shows separately in an isometric view of the brake clip 11 made up of a basic body 15 exists on which the actual friction lining 16 is arranged.

The main body 15 points for attachment to the lever 8th preferably a slot 19 on to be able to perform a slight pivoting movement in the tilted position of the wing. The brake 11 is fastened with a bolt in the slot so that the brake 11 with a pedestal 20 passing through the slot 13 the wing rail 2 grasps, on a lever 8th is attached.

The actual friction lining 16 points like the main body 15 two thighs 17 and 18 on, between which a kind of slot or a slot 14 is trained.

This outwardly V-shaped open slot 14 is limited laterally on 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 the slot is a stop opening 21 that approximates the diameter of the bolt 10 having.

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

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

Particularly preferred is the brake clip 11 from two different elements - the clasp-like basic body 15 and the likewise clasp-like friction lining 16 - composed of different materials.

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

4 shows that the main body 15 and the friction lining 16 preferably not only frictionally but also positively connected to each other. So are the integrally molded legs 23 of the basic body 15 with lateral recesses 24 provided, in which the friction lining 16 engages what the positive connection between the body 15 and the friction lining 16 manufactures.

This is advantageous because when closing the wing, so when moving out of the bolt 12 out of the slot 14 , Tensile forces on the friction lining 16 in relation to the main body 15 be applied. In addition, the deformation force of the legs is increased overall.

Preferably, the base body 15 with the friction lining 16 molded.

In summary are in the illustrated embodiment Among other things, the following functions realized: Fog as hidden horizontal corner bearing with opening limitation 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, trained for Turn-tilt elements (2-axis pivot point).
