D - 41189 Mönchengladbach Tape for doors, windows and the like

The invention relates to a tape of the type corresponding to the preamble of claim 1.

A generic hinge arrangement is known from DE 297 12 633 U1, in which the hinges are designed as so-called roller hinges. The "rollers" are the hinge parts of the hinge parts that are placed one above the other and through which the respective hinge pins pass, which have cylindrical outer circumferences of the same diameter and from which the fastening legs of the two hinge parts engage in the shadow groove, which is only slightly wider than the thickness of these fastening legs. The fastening takes place in the gap between the frame and the sash, right inside the same. Nothing of the fastening can be seen from the outside. The front surfaces of the frame and the sash or the sash frame can lie in the same plane. Only the "rollers" lie in front of this plane.

One problem with such hinges is that the distance between the frame and the sash, i.e. the size of the gap, must be precisely adjusted in order to achieve, for example, a good sealing of the gap by means of a suitable contact pressure of a lip seal.

In the known embodiment, as well as in the one from DE 197 39 930 A1, horizontal adjustment in the plane of the frame or sash is possible, but the adjustment can only be made in stages due to the design in which the lower part is provided with relief strips on its edge facing the upper part, which gradually increase in thickness, and the complementary design of the upper part (see DE 197 39 930 column 3, lines 38 to 65). In addition, the adjustment can only be made over a small area, since only the lower part is moved during adjustment and the hinge flap itself is fixed in the transverse direction by the screws. Furthermore, the manufacture of the hinge is complex, since the stepped design is provided directly on the hinge itself.

The invention is therefore based on the object of improving the horizontal adjustability of a generic hinge arrangement in the frame or sash plane.

This object is achieved by the invention set out in independent claims 1 and 15.

Because at least one of the fastening legs is penetrated by a threaded spindle which can be displaced in the adjustment direction and which rests on a wall of the frame or sash, it is possible to carry out a continuous horizontal adjustment in both directions without also having to make an adjustment perpendicular to the frame or sash plane.

To ensure that the fastening leg of the band part to be adjusted does not shift vertically or become tilted during the adjustment of the spindle, at least two cylindrical pins are preferably provided to guide the fastening leg in the adjustment direction. The cylindrical pins also bear a large part of the weight on the fastening leg.

At least one screw is preferably used to attach the fastening leg to the frame or sash. It is advantageous to

when the threaded spindle is penetrated by this screw in the middle in the direction of adjustment. This enables the screw to simultaneously lock the threaded spindle.

However, it is also possible to design the cylindrical pins as screws.

The mounting leg is then attached using these screws.

In a further embodiment, the threaded spindle is formed in two parts, with the parts engaging. For this purpose, the parts preferably comprise intermeshing, toothed collars.

However, it is also possible to additionally provide an actuating part, in which case preferably all parts have interlocking, toothed collars and the actuating part is in engagement with both other parts.

It is advantageous in the last two embodiments that only part of the threaded spindle has to be operated to adjust the fastening leg.

Even with multi-part threaded spindles, at least one screw is preferably provided to attach the fastening leg to the frame or sash. It is also advantageous if the threaded spindle or at least one of the parts is penetrated by this screw in the middle in the adjustment direction. This also enables the adjustment of heavy sashes under load.

According to a further aspect of the invention, it is possible to arrange two wedges between the fastening leg and a wall of the frame or wing, which wedges can be displaced against each other by an eccentric adjusting element, wherein it is advantageous if the adjusting element has two adjusting disks eccentric in opposite directions, each of which acts on one of the wedges.

Further details, features and advantages of the present invention will become apparent from the description and the drawing in which embodiments of the invention are illustrated.

Fig. 1 shows a hinge arrangement 100 on a fixed frame 4 with an aluminum hollow profile 5, the inner side 6 of which is aligned with the inner side 3 of an inwardly opening sash frame 1, which also consists of an aluminum hollow profile 2. The inner sides 3, 6 are flat and parallel to the frame or sash plane. The fixed frame 4 and the sash frame 1 leave a shadow groove 7 between them, which merges into a wider gap 8 towards the inside of the frames 1, 4. For thermal insulation reasons, the aluminum hollow profiles 2 and 5 are connected via plastic webs 9 to parts of the fixed frame 4 and the sash frame 1 on the weather side, which are also made of aluminum hollow profiles.

The sash 1 is pivotably connected to the fixed frame 4 in the direction of the arrow 11 by means of hinges 30. There are generally two or three hinges 30 distributed over the height of the sash. In the hinge arrangement 100, the hinges 30 are two-part, i.e. each hinge 30 consists of a frame hinge part 10 and a sash hinge part 20, which are pivotably connected to one another about the hinge axis A via a hinge bolt 12. The frame hinge part 10 comprises a hinge part 13 which receives the hinge bolt 12 and has a cylindrical, "roll-shaped" outer circumference, which is arranged close to the inside 3,6 of the hollow profiles 2,5. A fastening element, designated as a whole by 14, is integrally attached to the hinge part 13.

fastening leg. The flat, essentially level initial part of the fastening leg extends vertically and perpendicular to the inner sides 3,6 into the interior of the gap 8 between the hollow profiles 2,5. In this interior, the fastening leg 14 is angled twice by 90° each time. The free end part of the fastening leg 14, which extends perpendicular to the inner side 3 of the frame into the depth of the gap 8, is parallel to the initial part. In the gap 8, it rests against the inside of the wall 15 of the aluminum hollow profile 5, which runs perpendicular to the inner side 3 and delimits the gap 8 on one side, and is fixed there by the fastening screws 16, which reach through the end part and the wall 15 and engage in a threaded piece 17, which is arranged inside the aluminum hollow profile 5. Fixing pins can be provided between the screws to help fix the fastening leg 14 in the plane of its end part on the wall.

Similarly, the sash hinge part 20, which is arranged in one installation position under the frame hinge part 10 and which transfers the load of the sash to the frame hinge part 10, has a cylindrical, "roller-shaped" hinge part 23 with a fastening leg 24 which is bent twice at 90° each and which is designed similarly to the fastening leg 14 and whose flat initial part is arranged vertically and perpendicular to the inner sides 3, 6 and engages in the gap and whose end part rests against a wall 25 which runs perpendicular to the front surface 6 of the hollow profile 2 of the sash frame 1 and which delimits the gap 8 on the other side. The end part is also fastened to the sash frame 1 by means of a screw 26 which passes through it and the wall 25 and engages in a threaded piece 27.

The aluminum hollow profile 5 of the fixed frame 4 has a substantially rectangular cross-section and forms a step 18 on the edge adjacent to the shadow groove 7, which steps back from the inner side 6 and into which the first bend to the fastening leg 14 or 24 nestles. The gap is closed off inwards by a projecting area : : »· . ^: :: : : .**· ··: ··· .· : : :

19 of the inner wall of the hollow aluminium profile 2, which extends with its free edge over the shoulder 18 of the hollow aluminium profile 5 and there has a groove on the back in which a sealing profile in the form of a lip seal runs above and below the band 30, which extends around the frame opening and seals the sash against draughts.

As can be seen from Fig. 2 and 3, two cylindrical pins 22 are provided on the fastening leg 24, which penetrate the wall 25 and engage in corresponding holes 28 in the threaded piece 27 in order to fix the fastening leg 24 in the plane of its end part. This ensures that during the horizontal adjustment of the fastening leg 24, it does not slip and maintains its position and does not tilt.

A threaded spindle 21 is arranged essentially centrally in the end part of the fastening leg 24 and extends completely through it in a corresponding threaded hole. The threaded spindle 21 rests with its underside 31 directly on the wall 25. By turning the threaded spindle 21, the fastening leg 24 can be adjusted horizontally so that the end part of the fastening leg 24 either rests directly on the wall 25 if the threaded spindle does not protrude from the end part of the fastening leg 24 in the direction of the wall 25, or the end part of the fastening leg 24 protrudes from the wall 25 if the threaded spindle 21 protrudes from the end part of the fastening leg 24 in the direction of the wall 25. The extent of the distance between the end part of the fastening leg 24 and the wall 25 corresponds exactly to the protruding part of the threaded spindle 21. As already mentioned above, the cylindrical pins 22 prevent the fastening leg 24 from tilting or slipping during such an adjustment movement. To adjust the threaded spindle 21, it has a large hexagon pin 32. Inside this hexagon pin there is a hole 33 through the threaded spindle 21, through which the fastening screw 26 reaches in order to be fixed in the threaded part 27.

to be screwed, whereby the fastening leg 24 is firmly connected to the sash frame. At the same time, this arrangement ensures that the threaded spindle 21 is locked by the screw 26 against unintentional adjustment or loosening.

In the belt arrangement 200 of Fig. 4 to 6, corresponding parts in Fig. 1 to 3 are identified by the same reference numbers. Modified but functionally corresponding parts have a reference number increased by 100.

In contrast to the first embodiment, in the second embodiment the fastening of the fastening leg 124 is not effected by a central screw 26 that passes through the threaded spindle 21 to the threaded piece 27, but the cylindrical pins of the first embodiment are designed here as shaft screws 122, which, instead of the threaded pins, are inserted into correspondingly designed holes in the end part of the fastening leg 124 and engage in a corresponding threaded piece 127 via threaded holes 128. The shaft screws 122 thus serve both to guide the fastening leg 124 during adjustment and to fasten it to the wing 1. This dual function is made possible by the fact that the shaft 135 of the screws is relatively long and corresponding recesses 136 are present in the threaded piece 127. If the distance between the fastening leg and the wing is to be increased, the shaft screws 122 must first be loosened a little. During adjustment, the fastening leg then rests on the shafts 135.

The threaded spindle 121 is now adjusted relative to the fastening leg 124 not by a hexagon pin, but by a hexagon socket 132. In this case, the threaded spindle 121 is not additionally locked.

A combination of the lockable threaded spindle 21 with the shaft screws 122 is also conceivable.

In the belt arrangement 300 of Fig. 7 to 9, corresponding parts in Fig. 1 to 3 are identified by the same reference numbers. Modified but functionally corresponding parts have a reference number increased by 200.

In the third embodiment shown here, two shaft screws 222 are also provided for fastening the fastening leg 224, which are inserted into correspondingly designed holes in the end part of the fastening leg 224 instead of the threaded pins and engage in a corresponding threaded piece 227 via threaded holes 228. The shaft screws 222 also serve here to guide the fastening leg 224 during adjustment and to fasten it to the wing 1. ■

In contrast to the second embodiment, the threaded spindle 221 is made in two parts. The two parts 221 A, B comprise intermeshing, toothed collars through which the shaft screws 222 are inserted. The parts 221 therefore rotate about an axis passing through the screws. Due to the toothing of the rotating gear rings 240 A, B, it is not necessary to adjust the two parts 221 A, B separately. As soon as part 221 A is adjusted using a suitable tool that can be attached to the hexagon socket 234, the other part 221 B rotates in the opposite direction via the toothing. The parts are received in corresponding threaded holes 237 A, B in the end part of the fastening leg 224, the threaded hole 237 B having a direction of rotation that is opposite to that of the threaded hole 237 A, i.e. One part has a right-hand thread and the other a left-hand thread.

After adjusting the threaded spindle 221, the shaft screws 222 are tightened, which additionally locks the threaded spindle parts 221 A ₁ B.

In the belt arrangement 400 of Fig. 10 to 12, corresponding parts in Fig. 7 to 9 are identified by the same reference numbers. Modified but functionally corresponding parts have a reference number increased by 100.

In contrast to the above embodiment, the threaded spindle 321 is made up of several parts. The additional actuating part 321 C also comprises a toothed collar which lies between the other two parts 321 A, B and whose gear ring 340 C engages both the gear ring 340 A of one part and the gear ring 340 B of the other part. Due to the toothing of the rotating gear rings 340 A, B with the gear ring 340 C, it is no longer necessary for the two parts 321 A, B to have threads with different directions of rotation. As soon as the actuating part 321 C is adjusted using a suitable tool which can be attached to a hexagon socket 334, the other two parts 321 A, B rotate in the same direction of rotation via the toothing. The two parts are received in corresponding threaded holes 337 A, B in the end part of the fastening leg 324, wherein in this case the hole 337 B and the hole 337 A have the same direction of rotation or thread.

The actuating part 321 C is mounted on a bearing surface 341 embedded in the fastening leg 324 and rotates about an axis passing through this bearing surface. In this case, the actuating part 321 C does not need to be additionally locked, since the parts 321 A, B are already locked by the shaft screws.

In the belt arrangement 500 of Fig. 13 to 15, corresponding parts in Fig. 1 to 3 are identified by the same reference numbers. Modified but functionally equivalent parts have a reference number increased by 400.

In this embodiment, there are two wedges 440 A and 440 B between the fastening leg 424 and the wall 425 of the wing 1, which can be moved relative to one another by an eccentric adjusting element 421 after the fastening screws 422 have been loosened. By moving the wedges 440 A, B relative to one another, the distance of the fastening leg from the wall 11 is adjusted. For this purpose, the adjusting element 421 has two adjusting disks 441 A, B arranged one above the other, which are perpendicular to the axis of the adjusting element 421 in opposite directions and eccentric to the adjustment direction. The lower adjusting disk 441 A only acts on the lower wedge 440 A and the upper adjusting disk 441 B only acts on the upper wedge 440 B, for which purpose each of them has a bore adapted to the adjusting disk.

If the adjustment element 421 is adjusted by engaging a hexagon key in the recess 434 provided for this purpose, the lower wedge

440 A moves downwards and the upper wedge 440 B moves upwards. This reduces the gap 8. If the gap 8 is to be increased, the adjustment element is turned the other way round. The wedges then also move in the opposite direction and the distance increases.
20

To prevent the adjusting element 421 from shifting during rotation, it has a circumferential shoulder 442 which rests in a corresponding recess 450 of the fastening leg 424.

The fastening leg 424 itself does not slip because it is held transversely and perpendicular to the adjustment direction by the loosened shaft screws 422.
