Sash corner hinge for the corner bearing of a tilt and turn window, a door or similar.

The innovation concerns a sash corner hinge for the corner bearing of a tilt and turn window, a door or similar.

in which a (rolled) bearing sleeve formed from a sheet metal strip engages, via a connecting web, in one piece and/or firmly on a corner bracket that can be attached to the sash rebate peripheral surface, e.g. in front of or in a fitting groove, and in which the free ends of both legs of the corner bracket each engage with a support bracket in a form-fitting manner in the sash rebate peripheral surface, e.g. the fitting groove.

Sash corner hinges of the aforementioned type are already known and can be found, for example, in DE-U 94 20 513. This proposes a sash corner hinge in which a bearing sleeve engages a corner bracket via a connecting web, which engages in a fitting groove of a sash. The corner bracket, connecting web and bearing sleeve are formed as one piece. The free ends of both legs of the corner bracket engage in a fitting groove of the sash that is open at the top. The bearing sleeve is held up by a

■2-

Adjusting screw which forms an abutment for a bearing pin of the corner bearing fixed to the frame which engages from below. The pin can be adjusted horizontally using an adjusting screw, while the relative height of the sash to the frame can be regulated using the adjusting screw which closes the sleeve.

The disadvantage here is that an adjustment of the sash perpendicular to the frame, the so-called pressure adjustment, cannot be carried out.

DE 41 02 295 Cl shows a corner bearing assembly on the sash frame side for the corner bearing of a tilt-and-turn window or similar, whereby the bearing sleeve is connected to a corner bearing angle via a connecting web that runs out into a fastening plate. One or more eccentrically rotatable cylinder pins connected to the corner bearing angle, which engage in elongated holes in the fastening plate that surround them and extend in the longitudinal direction of the corner bearing angle, enable the pressure of the sash to be adjusted perpendicular to the plane of the frame, whereby form-locking elements hold the fastening plate and the corner bearing angle vertically.

The disadvantage here is that the corner bearing angle and the bearing sleeve or the connecting web consist of several parts. In particular, to connect the fastening plate to the corner bearing angle, form-locking elements that are complex to manufacture are necessary for both parts.

EP 0 400 180 Al describes a corner bearing for windows or doors, in which a first angle part is firmly attached to the sash while a second angle part is firmly coupled to the sleeve part. Both angle parts are connected via a

-3-

Adjustment device can be adjusted relative to each other so that the pressure of the sash against the frame can also be adjusted.

To achieve this function, a high level of manufacturing and material expenditure is necessary.

Finally, DE 43 37 626 Cl proposes a hinge for windows and windows or doors, in which a connecting web running parallel to the rebate surface of the sash is connected in one piece to the sleeve part protruding in front of the frame plane and is held between two plates. These are firmly connected to one another at a distance at one longitudinal end and form a pivot bearing for the connecting web of the sleeve part between them. At the opposite longitudinal end, the connecting web is pivotably supported by an eccentric mounted in the plates. A connecting pin is hinged to the middle of the end leg, which engages in a bearing piece that dips into the fitting groove of the sash and is covered by a fitting rail. The sash can be varied to the frame in the direction of the sash plane using a thread contained in the bearing piece.

The eccentric allows the connecting bar to pivot around the pivot point at the opposite end. The connecting pin can thus be moved perpendicular to the sash and frame plane, so that the pivoting movement results in a relative adjustment of the sash perpendicular to the frame plane, which corresponds to the aforementioned pressure regulation.

-4-

The disadvantage is that a large number of parts are required for the pressure adjustment and a high level of assembly effort is required.

It is the object of the invention to provide a pressure adjustment for the corner bearing of a tilt and turn window, a door or the like, which has a simple structure of the adjustment means and can therefore be manufactured cost-effectively.

The goal set after the innovation is achieved with a first solution principle by

that the corner bracket is provided with an eccentrically rotatable support member at least on its leg parallel to the bearing sleeve,

that the support member on the sash, e.g. in the fitting groove or formed by it, is assigned abutments parallel to the sash,

and that the corner angle can be elastically braced with the aid of the support member relative to its support brackets and relative to the wing corner transversely to the wing plane.

The advantage of this design is that a sash corner hinge designed in this way, in its simplest form, allows pressure adjustment with just one additional part. This reduces the material and assembly costs to a minimum.

For an application in which a sash corner hinge is to be used on a sash whose rebate surface is not provided with a fitting groove open at the top, the innovation provides for a different solution principle in which the corner bracket is provided with an eccentrically rotatable support member at least on its leg perpendicular to the bearing sleeve,

-5-

that the support member is assigned to the wing rebate peripheral surface, lying or formed by it, parallel to the wing

and that the corner angle can be elastically braced with the aid of the support member relative to the fastening means and the abutment opposite the wing corner transversely to the wing plane.

According to the first solution principle, it is also advantageous if, in the case of a sash with a circumferential fitting groove, the support blocks located at the free ends of both legs of the corner angle engage positively in the cross section of the fitting groove and the eccentrically rotatable support member near the apex of the corner angle is also positively received in the cross section of the fitting groove.

For this purpose, the support brackets of the legs of the corner angle are formed as tabs or tongues that are angled directly from the leg ends.

A further advantageous design is obtained with sash corner hinges of this type if the support member is an eccentric or crank pin that protrudes over the back of the corner angle leg and that engages in a sliding piece that can be rotated only and that is accommodated in the sash-side fitting groove so that it can be moved longitudinally but fits in cross-section.

A further advantageous embodiment results when the sliding piece is located in a notch of a lining piece, which appropriately fills the cross-section of the fitting groove in the sash rebate peripheral surface at least in the vertical direction.

The innovation for the second solution principle - i.e. for a sash without a surrounding fitting groove - still provides that

-6-

the abutment is a flat plate that can be fixed to the sash rebate perimeter surface, e.g. screwed on, in which the
eccentrically rotatable support member is axially fixed, while a head of the support member equipped with a tool attachment, e.g. a polygon, projects beyond the outside of the leg perpendicular to the bearing sleeve at the corner angle.

For this purpose, it is advantageous that the plate is supported by a
Bearing sleeve parallel joint is connected to the right-angled leg of the corner angle, and that the
Joint is at a lateral distance from the eccentric
adjustable piece link near the bearing sleeve
parallel corner angle leg.

The second solution principle of the innovation can also be applied if it is necessary to install an additional corner fitting part in the installation area of the sash corner hinge in a fitting groove on the rebate surface of the sash corner.
for example a so-called corner deflection
a drive rod fitting.

To this end, the innovation proposes

that the two legs of the corner angle rest on legs of a faceplate angle which are parallel to them,
for example, is part of the corner fitting, primarily the corner deflection,

that the horizontal leg of this angle bracket forms the wing-parallel abutment for the eccentrically adjustable support member and the joint parallel to the bearing sleeve
and that the vertical leg of the corner angle is only firmly anchored to the vertical leg of the faceplate angle at or near its upper end, for example by welding or
-riveted.

-7-

While it is also possible here in the simplest case to make the bearing sleeve and its connecting web in one piece with the vertical leg of the corner angle, in some cases after the innovation it may also be advisable for the bearing sleeve with its connecting web, in particular with a bend of the same, to overlap or overlap the vertical leg of the corner angle in the direction of its width, e.g. in the area of a length section cranked out by the material thickness of the connecting web, and to be firmly anchored to it, e.g. welded or riveted.

Further features and advantages of the subject matter of the innovation are described below using the embodiments shown in the drawings. It shows

Fig. 1 shows a sash corner band 1 formed in one piece from a sheet metal blank, consisting of a bearing sleeve 2 and a connecting web 3 that is firmly attached to it in one piece, as well as a corner bracket 4. The bearing sleeve 2 is a section of material rolled out of the sheet metal blank that runs tangentially into an inclined, flat piece of material, which further on has a bend 5, to which the connecting web 3 is connected almost at right angles. The bend 5 extends transversely and the connecting web 3 parallel to the sash plane.

-9-

The corner bracket 4 with its vertical leg 6 is connected to the connecting web 3 at approximately a right angle. This consists of a first section 7, a bend 8 that follows upwards and finally a support bracket 9 that closes the vertical leg 6 and runs transversely to it. The bend 8 is larger in width 11 than the width 12 of the leg 6 on an upper part 10 of its length. The support bracket 9 in turn has a different width dimension 13.

The horizontal leg 15 of the corner angle 4 consists of a first section 17 adjoining a vertex 16, which corresponds in its width 12 to the section 7 of the vertical leg 6 and which, in its further course, merges into a partial area 18, which in its width 19 corresponds approximately to the width 11. The horizontal leg 15 also ends in an almost transversely angled support bracket 20, which in turn has a width 21 that corresponds to the dimension of the support bracket 9.

When installing such a sash corner hinge 1 on a sash 22 with a circumferential fitting groove 31, the support blocks 9, 20 engage in this fitting groove 31 shown in Fig. 2. Only the partial areas 10 and 18 of the corner angle 4 rest on steps in the fitting groove 31, e.g. as shown in Fig. 2, formed by lateral projections 34.

The vertical leg 6 of the corner bracket 4 contains a hole 23 - not visible in Fig. 1, but recognizable in Fig. 3 - through which a support member 25 passes. The support member 25 is attached to the end of a shaft 24 passing through the hole 23 with a

-10-

manufactured collar 2 6, which prevents the support member 25 from coming out of the rotatable bearing connection with the hole 23 in the corner bracket 4.

The embodiment of the sash corner hinge 1 shown in Fig. 1 to 8 provides that the support member 25 has a tool engagement designed as a hexagon socket 27. The end of the support member 25 facing away from the collar 26 is a cylindrical thickening 28 which runs eccentrically to the central axis 29 of the shaft 24. The thickening 28 is dimensioned such that it projects beyond the inside of the leg 6 of the corner bracket 4 and can touch with its peripheral surface 47 the side walls of the fitting groove 31 - shown in Fig. 2 - or the facing edge surfaces of the projections 34 located therein.

Fig. 2 shows only one fitting groove 31 in the sash rebate 32. This fitting groove 31 is either designed as a so-called step groove incorporated in wooden profiles or, in the case of plastic hollow profiles, as the example shows, it consists of an undercut groove 33. This is delimited in steps by lateral projections 34 or by a step from the sash rebate 32. The clear dimension 35 that remains free between the projections 34 is therefore smaller than the dimension 36 that results above and below the projections 34.

The sash corner hinge 1 according to Fig. 1 engages in the assembled state with the support brackets 9 and 20 in the fitting groove 31 according to Fig. 3, whereby the dimension 13 or 21 is preferably slightly smaller than the dimension 35, which is obtained between the projections 34 of the fitting groove 31. The height 13a of the support bracket 9 is slightly smaller than the dimension 37, which is from the groove base 38 to the upper edge of the

-11-

projections 34. The widths 11 and 19 of the partial areas 10 and 18 correspond almost to the dimension 36 of the outwardly open step of the fitting groove 31 between its side walls 40.

The height dimension 14 of the offset 8 is slightly larger than the distance 39 of the projections 34 from the sash rebate 32 or the height of the side walls 40.

This design ensures that, on the one hand, the support blocks 9 and 20 of the corner angle 4 reach down to the groove base 38, but that, on the other hand, this corner angle 4 rests with the partial areas 10 and 18 of its legs 6 and 15 on the projections 34. The sections 7 and 17 of the legs 6 and 15 with the smaller width 12 do not lie in a form-fitting manner on the side walls 40 of the fitting groove, but have a certain lateral distance from them.

Fig. 3 shows the sash corner hinge 1 in an internal view. It can be seen that the corner angle 4 with the offset 8 rests on the projections 34 of the fitting groove 31. It can also be seen here that the partial areas 10 and 18 are provided with countersunk through holes 45 for receiving fastening screws (not shown). The section 7 of the leg 6 protrudes from the fitting groove 31 and only in sections do the offsets 4 6 rest on the projections 34. The support member 25 protrudes with its cylindrical thickening 28 over the inside or rear side of the vertical leg 6 from the section 7 into the fitting groove 31 and supports the sash corner hinge 1 against the side walls of the fitting groove 31 with its outer surface 47, e.g. between the projections 34 directed against each other there.

-12-

The outer surface 47 can be shaped according to the fitting groove, i.e. adapted to the inner shape of the fitting groove 31.

In the case of a groove profiling for plastic hollow profiles, as shown in Fig. 2, the outer surface 47 of the support member 25 can also contain, for example, a circumferential groove for receiving the projections 34.

For assembly, however, it is necessary to interrupt the projections in some areas at a point that does not correspond to the later end position of the support member 25. The interruption then allows the groove of the shell surface 47 to be placed in the area of the projections 34.

The support blocks 9 and 20 are supported on the one hand on the groove base 3 8 and on the other hand on the projections 34 of the groove 31. This prevents the fastening elements (not shown) that penetrate the corner angle 4 from causing deformation of the corner angle 4 when tightened to a high torque and also ensures that the corner angle 4 is additionally supported.

Fig. 4 shows a partially sectioned top view of how the support member 25 engages in the fitting groove 31. The adjustment of the support member 25 by rotating the eccentrically positioned thickening 28 against one of the side walls of the fitting groove 31 causes an elastic deformation of the entire part of the corner angle 4 located between the support brackets 9 and the part areas 10 and 18 adjacent to the side walls 40 of the fitting groove 31 perpendicular to the sash plane.

Because section 7 has a width 12 - not visible in Fig. 3 and 4 - smaller than the dimension 36 of the

-13-

Fitting groove 31 and also lies outside the first step formed by the projections 34 and delimited by the side walls 40, the usable spring length of the corner angle 4 is maximized.

Due to the elastic change in position of the axis of rotation 49 of the support member 25 relative to the longitudinal center plane 48 of the fitting groove 31, the sash can be given more or less distance from the frame transversely to its plane as required, or its contact pressure against it can be regulated.

Fig. 5 and 6 show an embodiment of a sash corner hinge 1, in which the support member 25 additionally has a sliding piece 50 encompassing the eccentric thickening 28, which is profiled in the longitudinal direction congruent with the fitting groove.

Fig. 6 shows a top view of a cross section through the support member 25 and the sliding piece 50 that surrounds it, whereby it can be clearly seen that the sliding piece 50 completely surrounds the support member 25 and has, for example, a T-shaped cross section.

The embodiment shown in Figs. 5 and 6 ensures that the forces occurring during adjustment, which act on the side walls 40 of the fitting groove 31, are distributed over a larger area. The sliding piece 50 must be able to carry out a minimal longitudinal movement in the fitting groove 31, because an adjustment of the support member 25 inevitably also causes a longitudinal thrust movement on the sliding piece 50.

Fig. 7 and 8 show a further modified embodiment in which the sash corner hinge 1 is additionally reinforced by a molded part 51 in order to accommodate larger sash weights.

The molded part 51 consists of an angle piece resting on the horizontal and vertical groove base 38 of the fitting groove 31, which contains through holes 52 through which fastening screws for the corner angle 4 can pass, preferably with play.

The molded part 51 prevents the corner angle 4 from being deformed towards the sash under load. In the sub-areas 10 and 18, the corner angle 4 rests directly on the strips of the fitting groove 31 (not shown here), so that there is no need to fear that the corner angle 4 will deform or slip. However, the section 7 is only supported on the sash by the offsets 46. The molded part 51 provides a desirable additional form stabilization of the corner angle 4 and also enables additional fastening screws to be attached without deforming the corner angle 4. The support member 25 lies here in a notch 51a in the upright angle leg of the molded part 51.

Fig. 9 and 10 show yet another embodiment of a sash corner hinge 1, e.g. for a sash that does not contain a circumferential fitting groove. The vertical leg 6 of the corner bracket 4 lies flat on the sash rebate surface over its entire length. The horizontal leg 15, on the other hand, has a support member 55 on its upper side. This can be moved via an actuator that is eccentrically rotatable in the horizontal leg 15.

-15-

··· »te

56 can be displaced sideways relative to the leg 15. The support member 55 is pivotably connected to the horizontal leg 15 of the corner bracket 4 for this purpose. In the illustrated embodiment, this is achieved by a cylindrically shaped pin 57 which engages in an elongated hole 58 extending, for example, in the longitudinal direction of the horizontal leg 15.

In particular, it can be seen from Fig. 10 that the horizontal leg 15 can taper like a wedge towards its free end 59, while the support member 55 has a constant width over almost its entire length. The support member 55 is secured to the wing by fastening elements (not shown) that penetrate the holes. The actuator 56 mounted in the support member 55 is mounted in the leg so that it can rotate eccentrically and can be rotated via the tool insertion or engagement.

The eccentric 62 of the actuator 56 is accommodated in an elongated hole extending in the longitudinal direction of the leg 15 and, by rotating it, allows an inclination of the center plane 64 of the leg 15 relative to the center plane 65 of the support member 55.

The wedge shape of the horizontal leg 15 allows the angle adjustment even then without having to fear a collision of the horizontal leg 15 with the fold peripheral surface when the support member 55 is sunk into a shallow recess in the fold peripheral surface.

The pressure adjustment in the embodiment shown in Fig. 9 and 10 is carried out by an elastic tension of the bending element.

-16-

vertical leg 6, which is rotated about the axis formed by the cylindrical pin 57 and the elongated hole 58 in a manner analogous to a change in the center plane 64 of the horizontal leg 15.

It is advantageous here that a force transmission is achieved by the different distances between the actuator 56 and the cylindrical pin 57 forming the axis, on the one hand, and between the cylindrical pin 57 and the vertical leg 6, on the other hand. As a result, relatively small and therefore precise adjustments of the wing pressure can be made with relatively large travel distances of the actuator 56.

In the embodiment of Fig. 9 and 10, the actuator 56 is designed as an eccentric rivet with a hexagon head. However, it is also possible to choose a different form of tool engagement, provided it fulfills an equivalent function.

For the sake of completeness, it should be mentioned that a sash corner hinge 1 according to Fig. 9 and 10 can of course also be used for sashes with a circumferential fitting groove. For this purpose, as Fig. 11 and 12 clearly show, it is then expedient to arrange the two legs 6 and 15 of the corner angle 4 resting on legs 67 and 68 of a faceplate angle 66 of an additional corner fitting part, which are parallel to them. This can be equipped on the inside, for example, with the functional elements of a so-called corner deflection. While the vertical leg 6 of the corner angle 4 is firmly anchored at or near its upper end 70 to the vertical leg 67 of the faceplate angle 66, for example welded or fastened by means of a rivet 71, the horizontal leg 68 of the

-17-

The faceplate 66 - instead of the plate 55 according to Fig. 9 and 10 - is used as a wing-parallel abutment. The eccentrically adjustable support member 56 as well as the joint parallel to the bearing sleeve 2, which is formed by a pin 57 and an elongated hole 58, are provided for the horizontal leg 15 of the corner angle 4. The pin 57 can, for example, be located on the leg 68 of the faceplate 66, while the elongated hole 58 is formed in the horizontal leg of the corner angle 4.

In the embodiment shown in Fig. 11, a sash corner hinge 1 is used, the bearing sleeve 2 of which, with a bend 3a of its connecting web 3, engages under the vertical leg 6 of the corner angle 4 in the area of a longitudinal section 72 bent out by the material thickness of the connecting web 3 in the direction of its width. The bend 3a is firmly anchored to this, for example welded or fastened via two rivets 73. The bend 3a of the connecting web 3 rests loosely on the outside of the vertical leg 67 of the faceplate angle 68.

The embodiment according to Fig. 12 of the drawing differs from that according to Fig. 11 basically only in that the bearing sleeve 2 is integrally fixed to the vertical leg 6 of the corner bracket 4 via its connecting web 3, as is also the case with the sash corner hinge 1 according to Figs. 9 and 10 of the drawing.

The pressure adjustment for the sash corner hinge 1 according to the embodiments of Fig. 11 and 12 is carried out in practically the same way as in the embodiment according to Fig. 9 and 10, i.e. by elastic tensioning of the vertical

-18-

Leg β of the corner angle 4. This is namely twisted in itself analogously to a change in the center plane 64 of the horizontal leg 15 about the axis formed by the cylindrical pin 57 and the elongated hole 58 on the length section lying between the rivet 71 and the horizontal leg 15.

The torsional force acting on the vertical leg 6 of the corner bracket 4 can be favorably influenced by the different lever ratios of the two lever arms of the horizontal leg 15 relative to the joint consisting of the pin 57 and the slot 58.
