Said bearing arm is guided telescopically on the pin seat into a bearing seat (16) on the leaf seat, leaving the bearing arm arranged on the outer surface of the leaf rabbet facing away from the fixed frame. The corner postioning parts are embodied as a hidden stop.

Description

The invention relates to a corner hinge of a corner bearing assembly for the Ecklagerung a sash of a window, a door or the like. On a fixed frame, comprising a fastened to the casement wing receptacle and a bolt receptacle having a support arm, wherein the support arm of the pin receptacle telescopically in a Tragarmaufnahme the wing receptacle is guided.

Particularly in the case of doors or windows with concealed fittings, the corner bearing assembly, which act between the fixed frame and the wing, must be arranged in the rebate air area. This means, on the one hand, that the corner bearing assemblies must be of compact design, since only a limited installation space is available. On the other hand, this means that despite low installation space and compact design, the Ecklagerbaugruppen must be designed so that they can carry heavy wings.

From the DE 196 50 085 C2 a Ecklager assembly has become known, which has a corner angle, on the horizontal leg of a bearing is provided with a set screws into which a pivot pin protrudes, which is connected to a bolt receptacle for a pivot pin. The adjusting air can be adjusted with the adjusting screw. The pivot pin is arranged in the horizontally extending Falzluftbereich, so that this Ecklagerbaugruppe is only partially suitable for a door or a window with a turn / tilt function, in which or even a scissors geometry must be arranged in the Falzluftbereich.

From the DE 93 01 655 U1 is a corner bearing assembly has become known in which a retaining rail is attached to the sash and a support rail is slidably mounted on the support rail. On the retaining rail a bolt receptacle for a pivot pin is provided. About an adjustment, the distance between sash and fixed frame can be adjusted. Both the support rail and the support rail are also arranged in the Falzluftbereich, which speaks against a compact design.

The object of the present invention is to provide a corner band of a corner bearing assembly, which is compact and suitable for heavy wings.

This object is achieved by a Eckband of the type mentioned, in which the support arm is arranged at least substantially on the side facing away from the fixed frame a Flügelfalzumfangsfläche and Ecklager assembly is designed as concealed fitting. This means that the support arm is advantageously arranged within a wing frame part of the casement. In particular, this means that neither the support arm nor the support arm receptacle of the wing receptacle protrude substantially, preferably not at all, into the rebate air area. This leaves enough room for a scissor geometry in the seaming air area. In addition, the support arm can be made stronger than the bands that are used for example in the prior art. The corner band can therefore be designed for larger loads. The corner band according to the invention can also be regarded as a corner angle, the horizontal leg is formed telescopically, wherein a telescopic tube is formed in the wing receptacle and the Tragarmaufnahme represents, and the pin receptacle is formed as part of the horizontal leg, said the support arm is the telescopic part cooperating with the telescopic tube.

A particularly secure holder and good guidance of the support arm results when the support arm surrounds the support arm at least partially circumferentially. Particularly preferably, the support arm surrounds the support arm completely or at least to a large extent. This can be realized in particular in that the Tragarmaufnahme is formed as a sleeve or blind hole.

A good anti-rotation of the support arm in the Tragarmaufnahme arises when the support arm is rectangular or square in cross-section and the Tragarmaufnahme is adapted to the cross section of the support arm.

A particularly compact design and a simple manufacture and assembly of the corner band results when the wing holder is integrally formed. In order to ensure a good support of the wing receptacle on the sash in this case, it makes sense to extend the Tragarmaufnahme having part of the wing receptacle over a multi-part design, in particular to extend the horizontal leg of the wing receptacle.

In a preferred embodiment of the invention can be provided for adjusting the distance between the bolt receptacle and the wing receptacle accessible in the vertical Falzluftbereich adjustable adjustment. The folded air can be adjusted very easily.

A preferred development is characterized in that the distance via an adjusting screw is adjustable, wherein the adjusting screw axially is arranged immovably in the bolt receptacle or the wing receptacle and cooperates with a thread cutout of the other part. The adjusting screw can be designed as a threaded pin or grub screw. It is particularly advantageous if the threaded cutout is already introduced during the manufacture of the wing receptacle or the bolt receptacle. This is particularly easy if the bolt receptacle or the wing receptacle are produced in a casting process.

In one embodiment, it can be provided that the horizontal leg of the wing receptacle comprises a cross-sectionally U-shaped tab. The U-shaped tab may overlap the Tragarmaufnahme having part of the wing receptacle and attached to the sash. As a result, the wing receiver can be held particularly securely on the wing.

Advantageously, a Ausdrehsicherung to prevent the complete separation of bolt holder and wing receiving is provided. The Ausdrehsicherung may for example comprise a recess in the bolt receptacle, in which engages a projection or a manifestation of the U-shaped tab. The bolt receptacle can then only be moved within the recess. This ensures that accidental unscrewing of the bolt holder is excluded.

In a particularly preferred embodiment, an articulation device for a scissors geometry is provided on the bolt receptacle, in particular the free end of the support arm. By this measure, the distance between the hinge device and the receiving part of the bolt receptacle can be kept constant even with different Falzlufteinstellungen. This is necessary for certain scissor geometries. The Anlenkeinrichtung can be formed for example as a bolt, hole or slot.

In order to allow an adjustment of the horizontally extending Falzluftbereichs, it is advantageous if the bolt receptacle has a vertical adjustment. For this purpose, the vertical adjustment, for example, a threaded pin, which is supported directly or indirectly on a pivot pin, have. Turning the threaded pin in or out raises or lowers the corner band. To avoid accidental adjustment of the height adjustment when opening and closing the sash, it must be ensured that the friction forces between the bolt receiver and the threaded pin are greater than those between the threaded pin and the axle bolt. To avoid this, a non-rotating corner bearing insert can be arranged in the bolt receptacle. Thus, the rotational movement is interrupted by the axle bolt to the set screw. An accidental adjustment is thus excluded.

In the scope of the invention, a window, a door or the like, with a fixed frame and / or at least one wing frame, wherein in Falzluftbereich between the fixed frame and sash at least one corner bearing assembly is provided which has a previously described Eckband. Such a window or such a door can be formed with very low Falzluftbereichen.

Preferably, the corner bearing assembly is designed as concealed fitting. So it is not visible with the wing closed.

In Fig. 1 the corner region of a wing 1 is shown. In the corner, a corner band 10 is arranged. The corner band 10 has a wing receptacle 11 and a bolt receptacle 12. From Fig. 1 it can be seen that the corner band 10 does not protrude over a Flügelfalzumfangsfläche 2 down. In particular, the corner band 10 is arranged essentially in a wing frame part 3. The wing receptacle 11 can be secured by fastening means, not shown, via mounting holes 4 on the wing 1.

From Fig. 2a it can be seen that the corner band 10 is designed as a corner angle. A vertical leg 13 and a horizontal leg 14 can be fastened to the wing 1. The horizontal leg 14 comprises a cross-sectionally U-shaped tab 15 which engages around a not visible in FIG. 2a support arm, which is arranged in a part of the wing holder 11.

In the partial sectional view of FIG. 2b, it can be seen that a support arm receptacle 16 for a support arm 17 of the bolt receptacle 12 is formed in the wing receptacle 11. The arrangement of the support arm 17 and the Tragarmaufnahme 16 of the wing receptacle 11 results in a telescoping horizontal leg 14 of the corner band 10. The adjustment of the bolt receptacle 12 relative to the wing receptacle 11 via an adjusting device 18 which includes a trained as a set screw adjusting screw 19, which axially is arranged immovably in a recess 20 of the bolt receptacle 12. The screw 19 cooperates with a thread cutout 21 of the wing receptacle 11. By turning the screw 19, the bolt receptacle 12 can be introduced into the wing receptacle 11. Since the screw 19 in the bolt receptacle 12 can not be moved, the bolt receptacle 12 follows the thread pitch when turning the screw 19, which applies to the thread cutout 21 of the wing receptacle 11. In this way, the lateral folding air can be adjusted.

For adjusting the upper and lower folding air, a vertical adjustment device 22 is provided, which comprises a threaded pin, not shown, which acts on a non-rotatably mounted Ecklagereinsatz 23 at which an unillustrated pivot pin is supported.

In the illustration of the corner band 10 shown according to FIG. 2c, the bolt receptacle 12 has been adjusted by means of the screw 19 with respect to the wing receptacle 11, so that a gap results between the support arm 17 and the wing receptacle 11 in the support arm receptacle 16. The illustration shown corresponds to the largest adjustable lateral folding air.

Evidenced the Fign. 3a and 3b, wherein the Fig. 3b shows an enlarged section of Fig. 3a, a Ausdrehsicherung 25 is provided. The Ausdrehsicherung 25 includes a recess 26 in the bolt receptacle 12th or in the support arm 17; in the one expression 27 of cross-sectionally U-shaped tab 15 engages. The extent of the recess 26 in the fold circumferential direction is greater than the extent of the expression 27. The interaction of the recess 26 and the expression 27, the movement of the pin holder 12 is limited. In particular, the bolt receptacle 12 can not be dismantled in the assembled state of the corner band 10.

According to the embodiment of a corner band 30 shown in FIG. 4a, the wing receptacle 31 is made in one piece. In particular, in this embodiment, the U-shaped tab is missing. At the wing receptacle 31 itself mounting holes 4 are provided.

As is apparent from the sectional view of Fig. 4b, the part of the wing receptacle 31, in which the Tragarmaufnahme 36 is formed, designed to be longer than in the embodiment of Figures 1 - 3b. The wing receptacle 31 is constructed in steps. In particular, the wing receptacle 31 is adapted to a stepped fitting part of the wing 1. The part 31 'comes to lie in a deeper fitting part groove and the part 31 "comes to rest in a fold-side region of the fitting part groove.

In the embodiment of FIG. 5, in the adjustment device 18, the screw 19 is arranged axially immovably in a recess 20 'of the wing receptacle 31. In contrast, it engages in a threaded cutout 21 'of the bolt receptacle 32.

The corner band 40 of FIG. 6a has a slot 43 in the wing receptacle 41, through which an articulation device 45 designed as a bolt protrudes. The sectional view of Fig. 6b can be seen that the hinge device 45 is arranged at the free end of the support arm 47 of the bolt receptacle 42. This means that regardless of the lateral Falzlufseinstellung the distance between the hinge 45 and the sleeve-like receptacle 48 for a pivot pin of the bolt holder 42 remains constant. In the embodiment of FIGS. 6a, 6b, the support arm 47 is extended compared to the previous embodiments, since the scissor geometry in this case, unlike before, where the wing receptacle is intended for articulation of the scissors geometry, to be articulated on the support arm of the bolt receptacle.

FIG. 7 shows a corner bearing assembly 49 with the corner band 10, which is attached to a scissors geometry 50. An invisible axle pin protruding from the handlebar 51 protrudes into the bolt receptacle 12. The scissors geometry 50 is fixed to a corner bracket 52 which is intended to be fixed to the fixed frame. Shown is an open position. When the sash is closed, the links 51, 53 overlap in sections in the rebate air area. The scissors geometry 50 is designed such that the wing is lifted off the fixed frame at the beginning of the opening movement, before the pivoting movement begins. The link 53 is articulated on the U-shaped tab 15, wherein the articulation device 15 is slidably disposed in a slot of the U-shaped tab. An adjustment of the lateral folding air does not affect the function of the scissor geometry therefore.

The scissor geometry 60 of the corner bearing assembly 59 shown in FIG. 8 has an additional link 61, which is articulated on the support arm of the bolt receptacle 42 of the corner band 40. The scissors geometry 60 requires a constant distance between the articulation point on the support arm and the axle bolt in order to obtain the same opening kinematics at different folding air settings.
