a door hinge known in which the support socket with a horizontal threaded bolts located outside of the horizontal center plane of the Trag-Euchse is. This threaded bolt is screwed into the door frame to attach the support bushing. The asymmetrical Arrangement of the threaded bolt makes it possible to compensate for a lowering of the door leaf in that the support bushing around Is pivoted 180 °.

, In this way, the height of the door can by twice

^ Distance by which the threaded bolt is against the horizontal median plane the support socket is offset, changed x ^ ground. the The sash height can therefore be changed, but only by a fixed amount. An exact compensation of the lowering is therefore generally not possible.

In addition, the entire door leaf does not normally lower itself evenly. Usually there is next one Change in shape in which the hinge-side edge of the door leaf roughly maintains its height, while the lowering at the opposite edge is at its maximum value achieved. Such V., - lowerings associated with changes in shape can at most through the previously known door hinge '' be partially compensated. Furthermore, the door leaf must be removed from the previously known door hinge, so that the support bushing can be pivoted to compensate for the lowering. With heavy door leaves this is a significant disadvantage.

From the German. Cffenle ^ ungsschrift No. 2 237 ² 177 is also known a hinge for Köb ^ l, ur.i to attach a furniture door to a furniture wall, the door running at right angles to the wall in question when closed. De ^- "a hinge fitting * has one

plate-shaped section which rests on the inner surface of the door leaf and is anchored in the door leaf by means of a dowel and a further anchoring part. The other hinge fitting has a horizontally running profile rod which is provided with a tab on one end on both sides. Each of the two tabs has a hole for the hinge pin. The profile bar is approximately C-shaped in cross-section, wherein the two C-limbs facing the furniture wall and converge to { ^'r) their free edges inclined toward. The profile bar is attached to an elongated, horizontally leading mounting plate that rests against the inner surface of the furniture wall. The mounting plate is trapezoidal in cross section and its side surfaces are inclined in such a way that the width of the mounting plate increases away from the furniture wall. The mounting plate therefore forms, like a dovetail, a guide for the profile bar, so that it can be displaced in the horizontal direction parallel to the furniture wall in question, but is held in place in the direction perpendicular to the furniture wall. The mounting plate has two dowels that are anchored in the furniture wall. One of these dowels, namely the one located closer to the hinge pin, is provided with a threaded hole and designed as an expansion dowel. The profile bar is provided with a screw slot and is clamped to the profile bar with a screw that penetrates this and is screwed into the dowel.

The hinge fitting formed essentially by a profile bar can be installed along the Mounting plate, i.e. in a horizontal direction along the furniture wall, moved and then using the mentioned Screw to be clamped. This allows manufacturing tolerances to be compensated. A door leaf

Deformation of the type described above ka "> n as a result however, cannot be compensated. When the door is closed, i.e. precisely when compensation it was especially important to have a good clasp To achieve the door, compensation is not possible because the essentially formed by profile bars Hinge fittings can only be moved at right angles to a plane parallel to the closed door leaf.

issue. Another disadvantage of this previously known hinge is that you have to completely separate the hinge fitting attached to the furniture wall from the furniture wall when maxi wants to replace the intermediate piece. This would be a major disadvantage with heavy door leaves. In addition, in this known hinge, too, the hinge fitting attached to the furniture wall is only clamped, although it also snaps into place a little at one end

so that it would not be suitable for fastening heavy doors due to its sliding ability. Furthermore, this previously known hinge would also not be suitable for door leaves that close flush with the frame.

A hinge is also disclosed in US Pat. No. 2 15 * ί 716 known to attach a door to a door sill. The door frame has a recess for each hinge, at their upper and lower boundary surface one each Elbow is arranged whose one leg on the bot-hitting boundary surface of the recess and whose other leg runs upstream.

These elbow legs have on their facing Seiton each ine groove into which the Hinge pin engages. The other two, vertical ones The legs of the second angle pieces are approached on their sides facing the first angle pieces. Between these inclines and one another you should turn vertical leg of the srsten elbow is a wedge-shaped intermediate piece arranged. The vertical legs of the first and second angle pieces si..d each ..it two screw holes. Each wedge-shaped spacer is provided with two incisions. One of the first

and the second angle piece as well as an intermediate piece are screwed to the frame together with two screws. The vertical legs of the second angle pieces each have two cams on their inclined sides. <3-sdes wedge-shaped spacer is provided with a number of holes for each cam. In the assembled state each cam engages in one of the holes. The two second elbows together form one on the Frame attached hinge fitting. The other hinge fitting is screwed to the door leaf.

According to US Pat. No. 2,154,716, the Mount the door leaf and then hang it in straighten it by slightly, but not completely, the screws that secure the elbows loosens and then moves the wedge-shaped spacers. With a heavy door leaf, however, it should be very difficult If the door leaf is attached and the screws are partially loosened, the spacers are disengaged from the cams to bring and adjust. Another disadvantage of the known hinge is that the vertical Legs of the second angle pieces in extreme positions of the Intermediate pieces only with a relatively small contact surface rest. Finally, it should be noted that the adjustability of the hinge fitting attached to the door frame a change in the shape of the door that has taken place in the door leaf level can only be compensated if the door leaf is in a position in which it runs at right angles to the apex of the angle pieces.

The invention is now based on the object of a door hinge to create a door leaf that closes flush with the frame ^ this enables the door leaf to be lowered, i.e.

The door leaf 2 is provided on its narrow side with two bores 2a in which the two support sleeves sit. The support plate 11 is inserted into a recess in the door leaf 2, so it rests against the door leaf 2 and is screwed tight to the door leaf 2 by means of a countersunk head screw 11a inserted into the countersunk hole 11a. The web 9a of the bracket 9 is inserted into the countersunk bores 9c, the incisions 13a and the bores 11b of penetrating countersunk head screws 15 are screwed immovably and firmly to the support bolts 12. The heads of the screws 15 each have a hexagonal recess for inserting a hexagonal wrench provided and the screws are designed as so-called Allen screws. The screws 15 naturally also connect the support plate 11 and that between this and the web 9a clamped intermediate plate 13 firmly to the bracket. The holes 2a are designed so that they form a tight fit together with the support bolts 12. The bracket 9 is so through the support bolts 12 anchored in the door leaf 2 on its narrow side, so that the latter mainly from the Support bolt 12 is carried.

The door leaf 2, which can have a weight of at least 150 kg, for example about 200 kg, is about Connected to the door frame 1 in a pivotable manner at the top and bottom by a door hinge 3 each. It is now possible that the Door leaf 2 is deformed in its plane in the course of time and moves towards its edge facing away from the door hinge 3 lowers. Such a lowering can be caused by the dead weight of the door leaf sox \ rie by the external stress causes xverden. Heavy loads arise, for example, in hospitals. when the doors with mobile beds or other means of transport

be pushed. If a lowering has now taken place, the screws 15 can be loosened a little. Then you can Pull out the intermediate plate 13 from the two door hinges and insert a thicker one at the bottom and one at the top insert a thinner intermediate plate. The screws 15 are then screwed tight again. When a Set of intermediate plates with finely graduated thicknesses is provided, the commonly occurring Reductions can be quickly and easily compensated and corrected in the manner described.

The support bolts 12 are permanently and non-rotatably connected to the support plate 11, for example by friction welding welded on. However, they can also be detachably connected to the support plate and, for example, with a be provided in this inserted neck, which has approximately a polygonal outline and non-rotatable in seated in a correspondingly designed hole in the platen.

The door hinge can be modified in various ways will. For example, more than one screw can easily be provided to the support plate on To attach door leaves. Furthermore, the number of support bolts could also be increased. The invention can also be used in the entirety of a door with frame and the new hinge can be seen.
