Hinges for doors or windows are well known. They serve to movably connect a wing of a door or window to a fixed frame and allow the door or window to be opened or closed. Hinges usually consist of two or three band parts, wherein at least one band part is mounted on a fixed frame and a band part on a wing. The two band parts are connected to each other via an axle pin to allow a pivoting movement of the wing. After assembly, it is often necessary to align the wing correctly, allowing a reliable closing of the wing is possible. For this purpose it is known to provide adjusting devices on the hinge band.

From the DE 20 2007 011 982 U1 For example, a hinged band for pivotally attaching a flap member, such as a door or a window, to a frame is known. The hinge strap comprises a hinge joint, which is formed from an upper and a lower bushing and a pin projecting into the bushing. Tape tabs are provided on the jacks, with a hinge tab attached to a flap member and the other hinge tab secured to the frame. The upper sleeve is divided into two space sections, wherein a front space portion for the pin and a rear space portion is provided for an adjusting mechanism for horizontal adjustment of the pin. In this case, a screw protrudes through the upper end of the pin. The screw head is arranged in an undercut groove of the upper hinge part.

From the EP 1 788 173 A2 is a Seitenverstelleinrichtung for a door or window hinge known with a recorded in a bearing eye axle, which has a horizontal or lateral adjustment, transverse to the longitudinal axis of the axle pin with its external thread engaging in an internal adjustment pin and in at least one socket in the bearing eye is included. It is envisaged that the bushing consists of a first part of the socket and a second part bushing by adjusting or rotating the adjusting a relative movement to each other and thereby contact the bearing eye such that the axle only a tilting and the alignment of its longitudinal axis maintaining horizontal or Can perform lateral adjustment movement.

From the DE 20 2006 002 236 U1 a tape for doors, windows or the like is known, with an adjusting device with which a hinge pin is displaceable parallel to itself, with an adjusting screw is provided with a hinge pin bushing which receives the hinge pin is adjustable.

From the DE 297 21 078 U1 a door or window hinge is known, with a hinged to a door or window sash hinge, which is hinged to a pivot bearing bolt on a frame hinge frame-fixed, with a rotatable relative to the pivot bearing bolt, equiaxed sleeve part on which the wing hinge is supported adjustable in height, and with a height adjustment of the wing band causing Schraubverstellteil. The Schraubverstellteil engages in adjustment thread of the sash.

The DE 299 20 128 U1 discloses a turning and swinging bearing comprising a frame-side member and a wing-side member, wherein the frame-side member has a receptacle for a pivot pin and the wing-side member has a pivot pin. The frame-side element and the wing-side element are each designed substantially disc-shaped. The elements each have on the side facing away from the pivot pin or the receptacle for the pivot pin means for attachment inside in a frame profile or a wing profile of a window.

From the DE 94 04 965 U1 is a corner bearing for a Drehkippflügel a window, a door or the like known, wherein a bearing bore has a slot-shaped cross-section and a bearing bore laterally offset transverse bore for receiving a threaded adjusting spindle is provided.

From the WO 03/095777 A1 a band for doors, windows or the like is known, which comprises at least one frame hinge part and at least one wing hinge part, wherein the at least one frame hinge part is pivotally connected to the at least one wing hinge part via a hinge pin forming a hinge axis. Furthermore, the band comprises a band bolt adjusting device provided in at least one of the hinge parts of the band parts, by means of which the band bolt can be displaced transversely to the hinge axis parallel to itself in the hinge part and which comprises a displacement drive. The displacement drive is formed by the hinge pin or by an adjusting element arranged inside the hinge pin or approximately concentrically with the hinge pin.

The common hinge bands is that the adjusting element, ie a screw or an adjusting pin, the axle pin penetrates, in particular screwed into this. A disassembly of the axle pin is only possible if the adjustment is dismantled. In addition, it is relatively complicated to produce an axle pin with a transverse bore which has a thread.

Object of the present invention is to provide a hinge, which allows a simple lateral adjustment while avoiding a transverse bore of the axle.

This object is achieved according to the invention by a hinge with the features of claim 1. The band part has a thread into which the adjusting means can be screwed. Furthermore, the adjusting means has a rear grip, with which it engages behind the adjusting sleeve at least in sections.

The adjusting means is screwed directly into the band part. About its rear handle the adjusting means cooperates with the adjusting sleeve. When screwing the adjusting means in the band part this can take the adjusting sleeve. Since the axle pin can be arranged in the adjusting sleeve, thereby also the axle pin is adjusted. The adjusting means may be coupled to the adjusting sleeve in such a way that the adjusting sleeve is carried along in the opposite direction even when the adjusting means is unscrewed and thus also permits an adjustment of the axle pin in the opposite direction. For this purpose, the adjusting sleeve, for example, have a screw head receptacle or collar receiving, in which a screw head or collar of the adjusting means is added.

The adjusting means has a Achsstiftanlage. When unscrewing the adjusting means of the band member, the Achsstiftanlage can then interact directly with the axle pin and move it within the bearing eye. As a result, it is not necessary to provide a screw head receptacle on the adjusting sleeve (on a side facing away from the axle pin).

According to a particularly preferred embodiment, the adjusting means is designed as a collar screw. The collar screw can project through a passage opening in the adjusting sleeve from the inside. The collar of the collar screw can rest against the adjusting sleeve from the inside and take with a screwing of the adjusting means in the band part the adjusting sleeve. If, on the other hand, the adjustment means is unscrewed from the band part, the collar of the collar bolt can rest on the axle pin and displace it. Since the axle pin is arranged in the adjusting sleeve, this takes with the adjusting sleeve in the adjustment.

Particular advantages arise when the band part has a passage opening in which the thread is formed or arranged for the adjusting means. As a result, the adjusting means is accessible from outside the band part. In particular, an adjustment without disassembly of the hinge is possible. Moreover, the adjustment is possible without conflict with the soffit.

Particular advantages arise when the adjusting means has a tool attack at its ends. This allows the adjustment are first inserted through the adjusting sleeve and screwed from its adjusting sleeve side end in the band part. Then, when the axle pin is mounted and this end of the tool adjustment means is no longer accessible, the adjustment means can be adjusted through the passage opening of the strap member by engaging a tool through the passage opening at the other end of the adjustment means.

Further advantages are obtained if a sleeve arranged in the bearing eye is provided, in which the adjusting sleeve is guided transversely to the orientation of the bearing eye adjustable. Through the socket, a guide for the adjusting sleeve can be created. This makes it possible to keep the inner contour of the bearing eye very simple and produce the band part cost. Preferably, the adjusting sleeve on opposite sides on projections which are guided in corresponding recesses in the socket. By this measure, it can also be ensured that the adjusting sleeve is always aligned vertically, so that tilting of the axle pin is prevented.

According to one embodiment of the invention can be provided that the guide of the bush for the adjusting sleeve is curved. This results in a good support under load of the hinge. There can be a better power transmission. In addition, a certain self-locking occurs, so that the adjusting sleeve does not move automatically.

Preferably, the guide has a radius whose center lies outside of the hinge part. Thus, it is possible, for example, that with a maximum lateral adjustment of +/- 2 mm only an adjustment of 0.1 mm perpendicular to be taken into account.

Preferably, the socket has a slot-shaped Achsstiftaufnahme. This ensures that the axle pin is not obstructed by the bush during the lateral adjustment.

It is particularly preferred if the adjusting sleeve is supported axially on the bushing. As a result, a good load transfer is possible.

The manufacturing cost of the hinge band can be reduced if the axle pin is formed without transverse bore. In particular, the axle pin may be formed as a simple cylindrical bolt.

If the band member has a second through hole facing the through hole in which the thread is formed or arranged for the adjustment means, a tool can be pushed through this second through hole to then engage the adjustment means and screw it into the band member.

Advantageously, a Achsstiftfixierung be provided. In particular, a grub screw may be provided, which is screwed into a further threaded through opening of the band part and projects into an annular groove of the axle pin in order to fix it axially. The through hole for the grub screw may be offset from the other through holes through which a tool can be engaged with the adjusting means. Through the grub screw and the bush and the adjusting sleeve can be fixed in the bearing eye.

In order to facilitate the relative movement of the band parts to one another, sliding discs can be provided in the upper and / or lower region of the band member. This will reduce the friction between the band parts, when they move relative to each other, reduced. In particular, a recess may be provided in the region of the end of the bearing eye, in which the sliding disk comes to rest. The sliding disk can be substantially flush with the upper or lower edge of the bearing eye or the band part.

Further features and advantages of the invention will become apparent from the following description of an embodiment of the invention, with reference to the figures of the drawing, which show details essential to the invention and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

The FIG. 1 shows an exploded view of a hinge strap 10 with a band part 11, which has a bearing eye 12 and a tab 13.
The flap 13 has openings 14, 15, via which the flap 13 can be connected to a wing or a fixed frame. In the bearing eye 12, a bush 16 is to be arranged.

The bushing 16 has on its circumference a longitudinally aligned web 17, which engages in a corresponding groove of the bearing eye 12. As a result, the bushing 16 is rotationally fixed in the bearing eye 12. On the other hand, the web 17 serves as an orientation aid and as an assembly aid in the assembly of the bushing 16.
Before the bushing 16 is inserted into the bearing eye 12, an adjusting sleeve 18 is laterally inserted into the bush 16. The adjusting sleeve 18 has laterally projections 19 which are adapted to corresponding recesses 20 of the bush 16. The projections 19, which are provided on both sides of the adjusting sleeve 18, are thus guided in the recesses 20. With the steps 21, 22, the adjusting sleeve 18 is supported axially on the steps 23, 24 of the bushing 16. The adjusting sleeve 18 has a receptacle 25 into which an axle pin 26 can be inserted.

The adjusting sleeve 18 also has an opening 27 through which an adjusting means 28, which is designed here as a collar screw, can be introduced. The adjusting means 28 is screwed to the band member 11. The opening 27 is approximately at the level of the passage opening 29 of the band member 11. Through the opening 29 through the adjustment means 28 is reached with a tool to screw the adjusting means 28 in the band member 11 can.

The adjusting means 28 has a collar 30 and a Achsstiftanlage 31. Furthermore, a tool attack 32 can be seen.

In the assembled state, the openings 33, 34 and 35 correspond. In the opening 35 of the band member 11, a grub screw 36 can be screwed, which then penetrates the openings 34 of the bushing 16 and 33 of the adjusting sleeve 18 and within the adjusting sleeve 18 with the axle pin 26th can cooperate, in particular can engage 26 in an annular groove of the axle pin to fix it axially.

In order not to hinder a lateral adjustment of the axle pin 26, the Achsstiftaufnahme 37 of the bush 16 is formed substantially elongated hole-shaped.

The mounting of the bush 16 is carried out in the embodiment from below. To prevent the sleeve 16 is pushed too far up, this has a collar 38.

The bearing eye 12 has a recess 39 in which a sliding washer 40 comes to rest. The sliding washer 40 minimizes the friction to another band part, not shown here, which is connected via the axle pin 26 with the band member 11. In the present example, it is provided that a further band part is also provided underneath the band member 11. In order to minimize the friction to this band part, a sliding disk 41 is also provided.

In the FIG. 2 is the hinge 10 in the assembled state, but shown without axle 26. With a tool 45, which is guided through the passage opening 29, the adjusting means 28 is screwed into the hinge part 11 and fixed there.

This is based on the sectional view of FIG. 3 clarified. The tool 45 extends through the openings 29 and 27 and engages the adjusting sleeve-side end of the adjusting means 28. The adjusting means 28 is screwed into a threaded through opening 46, which is arranged opposite to the passage opening 29. The collar 30 of the adjusting means 28 engages behind a wall 47 of the adjusting sleeve 18. In the illustration shown, the adjusting means 28 is screwed further into the through hole 46, the adjusting sleeve 18 and thus the receptacle 25 for the axle pin 26 moves to the left, since the federal government 30, the adjusting sleeve 18 moves to the left. It is understood that with the tool 45 on the adjusting means 28 can not be attacked through the opening 29 through when an axle 26 is mounted in the receptacle 25. In order nevertheless to be able to make a lateral adjustment, the adjusting means 28 still has a further tool engagement 48, which is accessible through the passage opening 46 therethrough. Thus, a lateral adjustment can take place when the axle 26 is mounted.

In the exemplary embodiment shown, the adjusting means 28 has a passage opening 49, which is formed as a hexagon socket. This makes it possible to attack and move from two opposite ends on the adjusting means 28 by means of a tool 45.

If the axle pin 26 is mounted and an adjustment of the axle pin 26 and thus of the adjusting sleeve 18 to the right, the adjusting means 28 is rotated out of the through hole 46 to the right. The fact that the Achsstiftanlage 31 abuts the axle pin 26, the axle pin 26 is moved to the right. The axle 26 is with stored only slightly or no play in the opening 25. Therefore, the adjusting sleeve 18 is moved with the axle 26 to the right.

In the FIG. 3 can also be seen that the surfaces 49, 50 of the bushing 16, which constitute the guide for the adjusting sleeve 18, and the surface 51 of the adjusting sleeve 18 are slightly curved. When adjusting the adjusting sleeve 18 in the axial direction of the passage opening 46 thus takes place also a slight pivotal movement of the adjusting sleeve 18 along the curved surfaces. The radius of the surfaces has a center which lies outside of the band part 11.

In the FIG. 4 It can be seen that the axle pin 26 has an annular groove 60. In this annular groove grub screw 36 engages when it is screwed into the band part 11, as shown in the FIG. 5 you can see. As a result, the axle 26 is fixed axially.

In the FIG. 6 it can be seen how a lateral adjustment takes place when the axle pin 26 is mounted. With the tool 45 is attacked through the passage opening 46 through the adjusting means 28.
