Description

The invention relates to a turn-tilt fitting for a window, door or the like of metal, e.g. Aluminum, having the features of the preamble of claim 1.

A turn-tilt fitting is eg from the EP-A-0 478 519 which has the features of the preamble of claim 1. The corner bearing housing of this turn-tilt fitting is clamped by means of a screw and a clamping element in the groove of a profile frame. The corner bearing housing itself has a receiving opening for the tab of the bearing strip, wherein the bearing strip must have been inserted into the corner bearing housing before it is fastened by means of the screw to the frame. The tab is additionally penetrated by the fastening screw. This is considered disadvantageous because the bearing tape must be threaded into the not yet fixed corner bearing housing and then the fastening screw through the tab into the threaded hole of the clamping element must be threaded. Another disadvantage is seen in the fact that in each case special corner bearing housing and associated bearing strips are required for left-struck and right-hinged window. This requires an expensive storage.

Moreover, from the DE-A-198 11 375 an angle deflection for metal frame known, however, which is also designed specifically for the left stop or for the right stop.

Also from the EP-A-1 074 687 a fitting for a tilt-and-turn window is known. Although this fitting can be used equally well on the right hinged and left hinged windows, but the fitting is not suitable to be attached to a metal frame can. In addition, high bending moments occur in this fitting, which require a stable design of the corner bearing housing.

From the DE-U-87 00 849 is a turn-tilt fitting with a corner bearing housing with bearing tape known, which are formed in mirror symmetry. This fitting is suitable for right and left battered wings, but the wing must not be too heavy.

The invention is therefore based on the object to provide a tilt-and-turn fitting, which is suitable for metal frame and which can be used for both left and right hinged windows, doors or the like. In addition, the pivot bearing should be as close to the frame, so that even large forces can be supported.

This object is achieved with a tilt-and-turn fitting, which has the features of claim 1.

Due to the inventive design of the corner bearing housing and the bearing strip as a mirror-symmetrical components, they can be used for left-battered as well as right hinged windows, doors or the like, which the Storage considerably simplified. In addition, the corner bearing housing is designed in the form of a housing block, in which the pivot bearing is provided for the tab or for the bearing strip. Due to the immediate vicinity of the pivot bearing to the frame very high forces can be absorbed or intercepted without damage to the corner bearing housing or the pivot bearing are to be feared.

In a further development, it is provided that the plane of symmetry runs horizontally when the fitting is installed. The plane of symmetry of the Ecklagergehäuses and the bearing strip is orthogonal to the pivot axis of the window, the door or the like. The Ecklagergehäuse and the bearing tape must therefore only be turned so that the previous upper side points down when used on a differently battered window. Due to the symmetrical structure, they can be used equally well for both sides of the window.

According to a preferred embodiment, the Ecklagergehäuse has in its receiving opening a bearing shell for the tab of the bearing strip. This bearing shell serves to compensate for any play occurring and the friction between the bearing strip and corner bearing housing reduce. In addition, the bearing shell serves to minimize the noise when tilting the wing and serves as a resistor for the heat and sound transmission from the corner bearing housing to the bearing band, ie from the frame to the wing.

Preferably, the bearing shell made of plastic and is provided with in the direction of the tab projecting ribs. In this way, air cushions are created, which further increase the effects mentioned above, wherein the ribs further reduce the friction of the bearing strip in the pivot bearing. The spaces between the ribs can also serve as pockets for lubricants.

Preferably, the bearing shell is mirror-symmetrical, wherein the mirror plane is orthogonal to the pivot axis of the window, the door or the like. In addition, another mirror plane is parallel to the pivot axis and orthogonal to the plane of the window, the door or the like. When inserting the bearing shell must therefore not be paid to their orientation, which facilitates the assembly much.

Preferably, the bearing shell is clipped into the receiving opening of the Ecklagergehäuses and locked in their final position. For this purpose, the bearing shell on locking lugs, which engage either in detent openings or engage behind corresponding shoulders on Ecklagergehäuse.

With preference the bearing band consists of plastic. By appropriate dimensioning can be ensured that the forces are transmitted safely, the bearing pin or the bearing axis for pivoting the window made of metal.

In another embodiment, it is provided that the corner bearing housing and the bearing strip made of metal, in particular die-cast. For this purpose, in particular aluminum or another light metal alloy is suitable.

In order to transmit high forces, the tab is formed breakthrough-free. This means that after the insertion of the tab in the.Aufnahmebohrung of the pivot bearing of the corner bearing housing, the fasteners for the corner bearing housing can not be operated. Thus, manipulations are no longer possible.

An advantageous embodiment of the invention provides the corner bearing housing has at least one sliding block for fixing the corner bearing housing to the frame. Instead of the sliding block can also be provided an eccentric. Both the sliding block and the eccentric are actuated by the corner bearing housing, in particular via openings, such as holes or the like. For this example, a hexagon wrench, with which the sliding block or the eccentric is rotated or pivoted. The sliding block or eccentric may be designed to be jammed in the groove of the frame or moved in the direction of a Nutensteges so that it jammed the Nutensteg between them and the Ecklagergehäuse.

Further advantages, features and details of the invention will become apparent from the following description in which a particularly preferred embodiment is described with reference to the drawing. The features shown in the drawing and mentioned in the claims and in the description may each be essential to the invention individually or in any combination.

The Fig. 1 shows a generally designated 10 Ecklagergehäuse, projecting from which two nuts 12 for attachment of the Ecklagergehäuses 10 in a (not shown) groove of a profile frame. In these nuts 12 screws 14 are screwed, which are provided for example with a hexagon socket. Between these two sliding blocks 12 is a centering projection 64, which facilitates the insertion of the corner bearing housing 10 in the profile groove and holds this until it over the Nutensteine is fixed.

Out FIG. 6 It can be seen that the sliding blocks 12 have a different shape from the circular shape, so that they can be pushed inserted between the groove strips in the groove. If they are in the groove, then they are rotated by 90 ° and engage behind the groove strips. By the stepped edge 60, they center the corner bearing housing 10 with respect to the groove. The corner 62 prevents over-rotation of the sliding block 12 in the groove and thus defines its locking end position.

The screws 14 are actuated by a suitable tool through the corner bearing housing 10 therethrough. For this purpose, the corner bearing housing 10 on its housing wall 16 openings 18 (see Fig. 3 ) in the form of holes through which the tool can be passed. If the screws 14 are screwed into the sliding blocks 12, then the sliding block 12 is moved in the direction of the housing wall 20, whereby the profile webs between Nutentein 12 and housing wall 20 clamped and thereby the corner bearing housing 10 is attached to the profile frame.

The corner bearing housing 10 also has a receiving opening 22 into which a bearing shell 24 is inserted. These Bearing shell 24 abuts the inner sides of the housing walls 16 and 18 and is supported on these. Clearly visible between the inner sides of the housing walls 16 and 20 and the bearing shell 24 are cylindrical-section-shaped cavities 26, which give the bearing shell 24 a certain elasticity in this area. In the region of these cavities 26 are formed on the two inner sides of the walls 28 and 30 of the bearing shell 24 inwardly projecting ribs 32, the sliding surfaces for a pivotally mounted tab 34 (see Fig. 4 ) form a bearing strip 36. Since the bearing shell 24 is made of plastic, thereby the friction between the bearing shell 24 and the bearing band 36 is considerably reduced.

The Fig. 2 shows a section through the bearing shell 24, from which clearly the ribs 32 can be seen. In addition, openings 38 can still be seen, through which the tool for actuating the screws 14 is guided. Finally, still elastically running retaining clips 40 can be seen, which have latching lugs 42 at their free end. These locking lugs 42 engage behind a shoulder 44 on the corner bearing housing 10, so that after insertion of the bearing shell 24 in the receiving opening 22 this is fixed captive. In this case, the retaining clips 40 nestle against bearing surfaces 46 or cover them these. The bearing surfaces 46 serve as a support for the bearing strip 36 and for its tab 34 and support the attached to the bearing band 36 window (not shown) from. For this purpose, the tab 34 has two part-circular portions 48, the radius of which corresponds in each case to the outer radius of the retaining clip 40. When tilting the window, the door or the like, the tab 34 is pivoted on this section 48 on the retaining clip 40 and the bearing surface 46. In each case, only the lower portion 48 sits on the lower retaining clip 40 and the lower bearing surface 46.

Immediately adjacent to the sections 48, the tab 34 each have a retaining lug 50. When tilted window, the upper retaining lug 50 touches the adjacent retaining clip 40 of the bearing shell 24 slightly. The bearing band 36 is thus inserted into the receiving opening 22 of the corner bearing housing 10 in that first one of the sections 48 is placed on its associated retaining clip 40 of the bearing shell 24 and then the tab 34 is fully pivoted into the bearing shell 24. In this case, the opposite retaining lug 50 passes the retaining clip 40 assigned to it and also enters the bearing shell 24. The two lugs 50 prevent removal of the bearing band 36 when attempting to do so without Only pivot out of the bearing shell 24 to pull.

The bearing strip 36 has an angular configuration and has a leg 52 which protrudes at right angles to the tab 34, to which side a bearing part of the pivot bearing, e.g. a bearing bush 54 for receiving a pivot pin forming the pivot pin 56 is integrally formed. The bearing strip 36 may be made of plastic, but the bearing pin 56 is made of metal for strength reasons.

From the figures it can be clearly seen that the corner bearing housing 10 is constructed mirror-symmetrically to a horizontal plane of symmetry 58. The bearing shell 24 is as out FIG. 2 can be seen, in addition to a plane parallel to the plane of symmetry mirror symmetry.

It can also be clearly seen from the drawing that the tilting plane corresponding to the plane of sections II-II and III-III (see FIG. 1 ) corresponds, is in the immediate vicinity of the sliding blocks 12 and thus to the profile frame, so that the leverage and moments can be kept small. In addition, it can be seen that the tab 34 is free from breakthroughs, so that the flow of force remains undisturbed within this tab 34. Further, the screw heads the screws 14 covered with bearing tape 36 of the tab 34.
