It is in threaded engagement with an axis bush (15) loaded on the pane or panel side. The axis bush is activated from rotary adjustment devices (17). The pivot bearing axis is provided with the rotary adjustment devices and is assembled with the axis bush in a rotary positive engagement manner.

Description

The invention relates to a door or window hinge, with a frame hinge and a wing hinge, which means a pivot bearing axis are hinged together, with a threaded part surrounding the pivot bearing axis, the is supported on the frame band load-bearing and with a Axle bush loaded on the sash hinge in thread engagement stands, which is acted upon by rotary adjusting means.

A door or window hinge with the aforementioned features is generally known from WO 96/23124. Window or door hinges have adjustment devices which make it possible to that the tapes were built within certain tolerances Differences in doors or windows due to height adjustment, Side adjustment or contact pressure can compensate. The WO 96/23124 shows a height-adjustable hinge for window or door shutters. There is one in a band sleeve non-rotatably mounted hinge. Located inside the tape sleeve there is still an intermediate adjusting bush. There is also a cap that functions as a cover the tape sleeve met upwards. Through this cap the adjusting bush can be twisted through with a tool and lifts the band sleeve by twisting it on a thread the band bushing. The structure has a multilayer Arrangement of different caps and sockets.

In contrast, the invention is based on the object a door or window hinge with the features mentioned above so improve that in a simple way a height adjustment of a possibly very difficult one Door or window sash is possible. Furthermore should the band can be expanded for multi-part wing bands.

This object is achieved in that the pivot bearing axis provided with the rotary adjustment means and with the axle bush is assembled in a rotationally and positively locking manner.

This arrangement is characterized by a special simple construction. There will not be multiple caps or sockets pushed over each other and attached to each other, but it is only a torsionally positive assembly of the Swivel bearing axis with the axle bushing and the rotary adjustment means required are located on the swivel bearing axis. By Twist the pivot bearing axis, which is easy from the outside with a Tool is possible, the height adjustment of the belt can be achieved with relatively little effort. The entire structure is compact and easy to assemble. Because the rotary adjustment means are built into the pivot bearing axis is also easily a multi-part structure, i.e. a structure with e.g. three band parts possible. This gives one good hold also for heavy sashes, e.g. at Fire doors or large windows. Even that heavy Sashes can be adjusted in the Readjust the pivot bearing axis when installed.

The tape can be designed so that the assembly the pivot bearing axis and the axle bushing of the wing hinge Insert the axle through the socket into the axle socket of the Frame strap until it hits a stop. This simple one Assembly of swivel bearing axis and axle bushing, the essential Form parts for the height adjustment of the frame hinge, is very helpful, especially when assembling heavy ones Wings. Accordingly, it also enables easy expansion and an easy adjustment. The parts needed for assembly can be used due to the insertion mechanism made in a similar shape in each band part be. This means an economically favorable production method.

It is advantageous if the torsionally positive assembly the swivel bearing axis and the axle bush with one Insert part is effected, both in an axially open Socket recess engages, as well as in a socket side open axle recess. The insert is easy to use and interchangeable. The structure enables simple power transmission from the swivel bearing axis to the axle bush. The Insert part enables recesses as coupling means.

It is advantageous if the socket recess on the axis insertion side according to the cross section of the insert is open. The insert is therefore minimal Game can be used. It enables a direct, namely free of space Power transmission without delay.

It is advantageous if the axis recess in the axial Towards an engaging outer circumference of the axle bushing or the insert is adapted. A projection on the axle bush or an insert used causes all the more better twist-fit, the more large contact surfaces the Recess in the axis, i.e. in the axial direction is expanded as far as possible. The power transmission is through this arrangement improved. In addition, the arrangement more stable. In addition, the insert can be axially parallel Sliding into the axle bushing can be installed smoothly.

A special training option for the band is that the insert part has an arched or corrugated leaf spring is, with its curvature or with its waves, in one of the Envelope of the spring shape corresponding to the curved recess intervenes. The leaf spring enables a good positive and non-positive connection of the swivel bearing axis to the axle bush is guaranteed. Manufacturing tolerances the recesses can be compensated. The leaf spring enables an additional hold or a backup of the Axle bush also axially relative to the pivot bearing axis.

It is advantageous if the leaf spring widened two Has ends that are in an undercut of a T-shaped Engage the socket recess. By intervening in the The undercut ensures a secure hold of the leaf spring. The leaf spring is held radially in a form-fitting manner. Turning the swivel bearing axis does not cause displacement the leaf spring. The leaf spring can be used with the axle bush can be assembled captively as a unit, even if the pivot bearing axis is not yet installed.

It is advantageous if the axle bushing is eccentric Bearing axis bore, and the T-shaped bushing recess at the radially strongest point of the axle bush lies. An eccentric hole in the axle bush for the Swivel bearing axis enables side adjustment. By the eccentric arrangement results in a radially different one Axle bushing thickness. This enables the T-shaped socket recess for the use of the insert be placed in a very stable position on the axle bushing can. Socket recesses of different sizes can be used to be incorporated, the use of different large insert parts or leaf springs. The order at the radially strongest point means the lowest possible Weakening of the axle bush.

Such an embodiment is advantageous in which the Threaded part engages with an external thread of the axle bush stands. As a result, the axle bushing can be comparatively long be formed and thus for a radially large area Provide support for the swivel bearing axis. Furthermore, the threaded part in a simple manner with a section surrounding it of a band body are connected in a rotationally positive manner. The threaded part has comparatively large radii, so that accordingly low surface pressures in the area of Thread engagement with the axle bushing and its further provide axial support.

It is advantageous if the rotary adjustment means has an inner non-circular recess is at one end of the pivot bearing axis. In the inner non-circular recess, e.g. a Intervene from outside, which prevents the twisting of the Swivel bearing axis and thus a height adjustment of the wing enables. Since the rotary adjustment means at the end of the Pivot bearing axis can be shorter or longer Swivel bearing axles for two-part or multi-part, in particular three-part tapes are used without the Means for the positive locking between the pivot bearing axis and the axle bushing would have to be changed.

It is advantageous if a hinge body of the wing hinge supported above the threaded part on the axle bush and is radially non-rotatably connected with formations and the threaded part axially displaceable but encompasses torsion-proof. Of the Structure allows that with normal operation of the built-in sash hinge no adjustment of the height adjustment e.g. is caused by pivoting the wing. The Height adjustment should be in normal everyday operation of the Tape to be irreversible. Since the axle bushing around the inside Pivot bearing axis is attached within the belt body, no built-in parts of the belt can be seen from the outside. Either the threaded part and the axle bush move together with the hinge of the wing hinge.

It is advantageous if the threaded part on a Bearing ring is supported, which rests on the frame band and the threaded part with a ring projection inside the axle bush surrounds. By supporting the threaded part on the Bearing ring is a very when the wing is turned low-friction movement possible by rotating the bearing ring. The ring projection ensures a radial positive fit and a secure fit of the bearing ring. Because the ring projection lies inside the band body, it is from the outside not recognizable and the wing hinge or hinge body guaranteed a good impression. The bearing ring enables further that even with an eccentric attitude the pivot bearing axis by turning the axle bushing none There is a reduction in the support on the frame band.

It is advantageous if the hinge body of the wing hinge is provided on the axis insertion side with a recess which a recess required for receiving the threaded part corresponds, and with a radially supporting the axle bush Filler is filled. Since the recesses on the The wing hinge can correspond to the ends of the axle bushing be used for the right-hand stop as well as for Left stop. The filler determines a radially secure Stop above the torsionally positive connection of the Swivel axis with the axle bush.

It is advantageous if a above the wing hinge there is another frame band, if necessary a a sealing ring covering the gap on the filler lies on. The design of the frame band with at least a wing hinge and two frame hinges ensures one good radial support of the swivel bearing axis and thus one secure hold of the wing when it causes high loads. The rotary adjustment of the swivel bearing axis can in the upper end of the pivot bearing axis within the upper Be arranged frame tape. The one from the wing hinge Arrangement of the rotary adjustment means prevents the desired Height adjustment not. It is only necessary make the pivot bearing axis longer. It is stable enough to withstand larger turning forces easily to the distant point of the positive locking transfer. The sealing ring ensures a handsome optical impression. It can also be a pollution prevent.

a detail of a modified embodiment of a door hinge in the area of the torsionally positive assembly between the pivot bearing axis and the axle bush.

The illustrated embodiment is a three-part Door hinge, consisting essentially of a hinge 12, the articulated by means of a pivot bearing axis 13 with two Frame straps 11 is connected. The wing hinge 12 is with a mounting screw 16 shown for example attached and not shown a wing of the door further attachment points 16 '. The frame bands 11 are each on a frame of the door, not shown attached, for example at the specified attachment points 11 '. The wing hinge 12 has a sleeve-like hinge body 12 ', in which the pivot bearing axis 13 is radial supporting axle bush 15 is located. At its ends is 13 '' the pivot bearing axis 13 mounted in axle bushings 23, which each within the sleeve-like band body 26 of the upper or of the lower frame band 11. All axle bushings 15, 23 are traditionally designed to be the one to them requirements regarding the resilience and the Ease of movement must suffice. For example, they exist made of plastic or cast metal.

2 shows that the axle bushing 15 is provided with an eccentric bearing axis bore 15 ^IV , in which case the bushing axis 25 is arranged eccentrically to the longitudinal axis 27 of the pivot bearing axis 13 by the distance shown. This ensures that when the bearing bush 15 is rotated by 180 degrees, a corresponding displacement of the pivot bearing axis 13 takes place, namely for the purpose of lateral adjustment of the wing, with which the wing can be aligned within the frame. With such a side adjustment, the axle bushings 23, which likewise have eccentric bearing axis bores, must also be adjusted accordingly. If the axle bushings 15, 23 are only rotated by 90 degrees, this results in a correspondingly combined side and pressure adjustment with pressure increase or pressure reduction, depending on the setting direction. The respective position of the axle bushings 15, 23 is secured against unintentional twisting. For this purpose, end caps 28 are used, for example, which engage with protrusions (not shown in detail) in outer recesses 29 of the axle bushings 15, 23 and at the same time also in inner recesses 30 of the band body 26, which are designed according to FIG Cross section is filled by the mentioned cap projections, so that a rotation of the axle bushings 15,23 is not possible without removing the caps 28 beforehand.

The load transferred from the wing to the wing hinge 12 is transferred to the axle bushing 15 with the belt body 12 '. For this purpose, the band body 12 'has an annular support surface 31 on a corresponding annular support surface an annular projection 32 rests on the support surface 31 engages. In the area of the support surface 31 on the projection 32 and on the band body 12 'interlocking Coupling means, not shown, are present, which is an unwanted Rotation of the band body 12 'relative to the axle bush 15 prevent. Such coupling agents are for example Projection 32 cams and recesses adapted to these cams of the band body 12 '.

The axle bushing 12 'is provided below the projection 32 on its outer circumference with an external thread 15 ^V which engages in an internal thread of a threaded part 14. The threaded part 14 thus encompasses the lower end of the axle bushing 12 'and also the pivot bearing axis 13. The threaded part 14 is supported on a bearing ring 20 which rests on the frame band 11. The bearing ring 20 has an annular projection 20 which surrounds the threaded part 14 on the outside, but is arranged inside the band body 12 ', so that there is a corresponding sealing of the threaded area. The bearing ring 20 covers the joint between the lower end of the hinge body 12 'and the upper end of the hinge body 26 of the lower frame hinge 11. Similarly, a sealing ring 22 covers a joint between the upper end of the axle bushing 12' and the lower end of the hinge body 26 of the upper frame hinge 11. In both rings 20, 22, the pivot bearing axis 13 is located in an elongated hole 20 ″ or 22 ′, so that corresponding space is available for adjusting the pivot bearing axis 13 when the bearing bushes 15, 23 twist to adjust the wing position because the rings 20, 22 are radially positively arranged in their band bodies 12 ', 26.

The three-part band shown is mainly for larger wing loads thought. Despite such larger wing loads the wing must be able to be pivoted easily, so without larger storage or Frictional forces result. This can be done especially at the load transfer point the wing hinge 12 to the frame hinge 11 occur, So at the bottom of the bearing ring 20. To here The lower frame hinge is to avoid greater frictional resistance 11 provided on the sash hinge with a roller bearing 33, which in turn is supported on the wing bush 23, which again with a support projection 34 on a support ring surface 35 of the band body 26 rests.

The upper frame band 11 is the lower frame band 11 trained accordingly except for the rolling bearing. It broadcasts no axial forces, but only serves the radial support of the pivot bearing axis 13. This is the upper frame hinge 11 as far axially from the wing hinge 12 posted that the distance shown in Fig.1 between the bearing bush 23 and the sealing ring 22 results. The distance is such that a height adjustment the wing hinge 12 is not hindered. The arrangement shown the axle bush 23 at the upper end of the pivot bearing axis is saved in a manner not shown, e.g. With a grub screw that fixes the bushing 23 on the body 26.

The thread engagement between the bearing bush 15 and the Threaded part 14 opens up the possibility of height adjustment to effect using the pivot bearing axis 13. A Rotation adjustment of the bearing bush 15 leads to the fact that Bearing bush 15 depending on the direction of rotation within the threaded part 14 raises or lowers, the threaded part 14 with is connected to the band body 12 'in a rotationally fixed manner, e.g. with the shown projections 14 'in corresponding axially parallel Grooves of a recess 12 '' 'engage which the threaded part 14 receives. When turning the Socket 15 can be the torsionally positive connection between its projection 32 and the support surface 31 of the band body 12 'can be overcome.

To cause the axis bushing 15 to twist these are connected to the pivot bearing axis 13 in a rotationally locking manner, which in turn rotary adjustment means 17 in the form of a Has non-circular recess. The inner non-circular recess is a hexagon socket into which an Allen key is inserted can be removed when the cap 28 is removed. A twist such a key leads to a corresponding one Rotation of the pivot bearing axis 13 and with a Transfer insert 19 to the axle bushing 15.

1, the insert 19 is a curved leaf spring, which has two facing ends 19 ''. This Ends 19 ″ are widened according to FIG. 2 and engage in one Undercut 15 '' 'of a T-shaped socket recess 15 '. This socket recess 15 'is open vertically at the top. Of the Installation of the leaf spring is done in such a way that from above the open end of the socket recess 15 'is inserted, until it touches the end of this recess Then she can do not fall out radially because the widened ends 19 '' prevent this. The same applies to that in Fig. 3 insert 19 shown, which has the shape of a corrugated Has leaf spring.

The curvature 19 'or the waves 19' '' of the described Leaf springs engage in an axle recess 13 ', the circumferential rotation is designed so that a relative rotation the pivot bearing axis 13 to insert 19 not possible is. Each rotation of the axis 13 leads to a corresponding one Rotation of the axle bushing 15 is supported the pivot bearing axis 13 once at the curvature 19 'and the other embodiment on the shafts 19 '' ' Leaf spring off.

The axis recess 13 'is essentially in the axial direction so arched that its curvature of the envelope of the Spring shape corresponds. The tolerances can be designed in this way be that the leaf spring is slightly compressed radially becomes. The result is a correspondingly tighter Seat of the pivot bearing axis 13 in the axle bushing 15.

The pivot bearing axis 13 is assembled with the wing hinge 12 in such a way that it is inserted through the bearing axis bore of the upper frame hinge into the bearing axis bore 15 ^{IV of} the axle bushing 15 and is pushed so far until the leaf spring engages in the bushing recess 15 '. The pivot bearing axis 13 is accordingly removed while overcoming the latching force of the leaf spring in the opposite axial direction, provided that it is not pulled out as well.

The pivot bearing axis 13 is inserted by limited an attack. In Fig.1 is in the lower frame band 11 a stop 24 in the form of an annular projection of the axle bushing 23 shown. Instead, or in addition to it the insert 19 serve as a sling. This is especially true when a rigid insert instead of the leaf spring is used, for example a feather key. In In this case, however, the pivot bearing axis 13 would have to be up to be slotted continuously at the bottom so that the Axis 13 with its slot pushed over the rigid key can be.

The wing hinge 12 is for both right and for Left stop trained. This is done by simply turning reached, then the one for receiving the threaded part 14 serving recess 12 '' 'comes to lie above. On the other hand the recess 12 ″ shown at the top in FIG. 1 comes to the bottom lie and can grip around the threaded part 14, since they are also is formed as the recess 12 '' '. So that the radial support the pivot bearing axis guaranteed in any case , the recess 12 ″ or 12 '' 'provided with a filler 21, which is the radial support between the axle bushing 15 and the belt body 12 ' ensures, as well as the axial support of the sealing ring 22.

The pivot bearing axis 13 points in the center of the sash hinge 12 a constriction 36 with which the rotation of the pivot bearing axis 13 when assembled with the wing hinge 12 before Locking the leaf spring is facilitated. Also intervenes in this constriction 36 a cross pin to secure the axial position the pivot bearing axis 13.

In Figure 2 it is shown how the wing hinge 12 and a Frame hinge 11 with fastening screws 16 for fastening are formed on a frame. The screws 16 grip each in a fastening nut 37 with guide means 38 for rod guidance behind a hole in the frame is formed, in which the wing hinge 12 and the frame hinge 11 each engage with centering bushes 39. A cover cap 40 is from the frame side with a fastening screw 41 attached to the wing hinge, from the back of the wing hinge 12 ago, so that they only when open Door leaf can be removed, which prevents the fastening screws 16 with the door leaf closed can be turned out.
