Another adjustable door hinge is the subject of EP 2 390 446 A1 ,

An adjustable hinge, especially a furniture hinge is off EP 0 200 019 A2 or the DE 30 04 313 A1 known.

Against this background, the invention has for its object to provide a door hinge with two hinged hinge parts, wherein on one of the hinge parts an adjustment in two directions with structurally simple means is possible.

Starting from a door hinge with the features described above, the object is achieved by a door hinge according to claim 1, wherein a fixing means for clamping locking a front portion of the body, the intermediate piece and the insert passes through.

In the case of a dissolved fixing agent, the base body can be moved in a controlled manner relative to the insert along the two linear guides without tilting. As a fixing means according to the invention a screw is provided, which engages in a threaded piece, being pulled by tightening the screw of the insert and the intermediate piece of the threaded piece clamped against the body.

By the first and the second linear guide precise adjustment in two directions, in particular two mutually perpendicular directions is possible without the body is tilted relative to the insert or twisted. Furthermore, they can be used for adjustment provided linear guides are easily formed on the comparatively small intermediate piece.

The first and the second linear guide can be realized by elongated holes or groove guides, wherein at least one projection on one of the parts leading to one another is received in a groove of the other part to form a groove guide. Particularly preferred is an embodiment with an elongated projection in the direction of the straight guide or with two spaced-apart projections in order to avoid tilting with respect to the intended direction of movement. According to a preferred embodiment of the described embodiment, it is provided that the intermediate piece for forming the groove formed as a first linear guide and the second linear guide each having at least one projection which engages in an associated groove on the base body or the insert. The base body and the insert can be correspondingly easily formed, wherein the grooves described can also be subsequently produced easily with high accuracy. Since the intermediate piece is only intended to allow the described adjustability in two directions, this can be relatively small and thus easy to manufacture. Apart from the formations provided for guiding a simple plate or disc shape is appropriate.

For the production of the intermediate piece, this results in different possibilities. Due to the simple shape is an injection molding into consideration. In addition, the intermediate piece can also be formed from a formed sheet, for which only a punching is necessary. The described projections can then be easily formed out of the sheet. It is also conceivable to use projections in the form of pins or the like in bores on the intermediate piece. At a Such an embodiment, the projections may also be formed of a particularly resistant and / or low-friction material.

Since the intermediate piece is arranged between the base body and the insert, the first straight guide on the one hand and the second straight guide on the other hand are expediently formed on opposite sides of the intermediate piece. According to the invention, two hingedly cooperating hinge straps are provided as the connection of the strap parts, wherein the strap parts each comprise the base body and two inserts and wherein on the inserts one of the hinge brackets is rotatable and the other hinge strap is rotatably and slidably received along a guide slot of the inserts ,

These hinge parts can then be provided for a concealed arrangement between the door leaf and the door frame in recesses of the frame and in the narrow side of the door leaf.

By means of the intermediate piece, an adjustment in two directions, preferably perpendicular to one another, is made possible. In particular, it can be provided that the at least one insert is adjustable relative to the main body along a vertical direction running parallel to a pivot axis of the door hinge and perpendicular thereto along a horizontal direction. Based on the closed position of the door leaf, an adjustment in a further horizontal direction on the other band part can be realized, so that a total of three adjustable door hinge is provided.

The insert is preferably a metal injection molded part. This results in the advantage that the formations for providing the second straight guide are comparatively simple and can also be readily formed in a metal injection molding process. Alternatively, a groove in a metal injection molded part can also be generated later. The production is thus particularly cost possible. In order to minimize overall cost with good stability and function of the door hinge, the base body can be formed as a one-piece part of sheet metal. Here too, the formations required for the first linear guide can be easily generated.

The invention generally relates to a door hinge 1 with two hinged hinge parts 1a, 1b, wherein one of the hinge parts 1a has a base 2a for attachment to a door frame or door leaf and at least one relative to the base 2a in two directions adjustable insert 3a. One possible embodiment of such a door hinge is in the Fig. 3 represented, wherein the two band parts 1a, 1b each have a base body 2a, 2b and two inserts 3a, 3b. While the inserts 3a of the first hinge part 1a relative to the usual arrangement of the door hinge 1 in the mounted state in the vertical direction z perpendicular thereto in a first horizontal direction x relative to the associated base 2a are adjustable, is a further adjustment in a second horizontal direction y the second band part 1b is provided perpendicular to the front side of the corresponding base body 2b, wherein the inserts 3b are each positionable with one adjusting spindle 4 relative to the associated base body 2b on the second band part 1b.

The exact configuration of the first hinge part 1a results from the in the Fig. 1 in a exploded view shown detail. It can be seen that an insert 3a is provided above as well as below the hinge bracket 5 connected to each other at a rotation axis D, wherein an intermediate piece 6 is arranged between each of the inserts 3a and a front portion of the base body 2a. The intermediate piece 6 is plate-shaped and has on its upper side and on its underside formations which, with associated formations on the basic body 2 a, are a first one Straight guide and with associated formations on the insert 3a form a second straight guide.

In the illustrated embodiment, the intermediate piece 6 on its upper side two projections 7 which engage in a along the first horizontal direction x extending groove 8 and thus together with the groove 8 form a groove guide. The groove 8 is in the Fig. 1 concealed.

Of the Fig. 2B It can be seen that the intermediate piece 6 has at its bottom slots 9, which extend in the mounted state in the vertical direction z and engage in the webs 10 of the associated insert 3a. The slots 9 and the webs 10 together form the described second straight guide.

With the intermediate pieces 6, the two inserts 3a of the first hinge part 1a are precisely adjustable relative to the base body 2, whereby tilting is avoided by the two linear guides.

In order to fix the inserts 3a to the base body 2a in the desired, set position on the first hinge part 1a, a fixing means in the form of a screw 11 is provided, which passes through a front portion of the base 2a, the intermediate piece 6 and the associated insert 3a and engages in a thread of a threaded piece 12 arranged below the insert 3a. By tightening the screw 11, the insert 3a and the intermediate piece 6 are pulled by the threaded part 12 by clamping against the base 2a and fixed so. In the fixed state, the door hinge is secured against unintentional adjustment, after a loosening of the screw 11, a new adjustment is possible.

As is clear from the Fig. 3 For connecting the two hinge parts 1a, 1b, the hinge brackets 5 connected to each other on the rotation axis D are provided, the hinge brackets 5 respectively rotatable on the inserts 3a, 3b of one of the hinge parts 1a, 1b and on the inserts 3b, 3a of the other hinge part 1b, 1a are slidably received along a guide slot 13. The Fig. 3 shows in this context, a development of such a per se known arrangement in which on each insert 3a, 3b two guide slots 13 are arranged, of which a guide slot 13 remains unused. In the context of the described development, there is the advantage that the inserts 3a, 3b both left and right, that can be used on one of the band parts 1a, 1b both above and rotated by 180 ° below the hinge bracket 5 can be used.

The arrangement of the intermediate piece 6 between the base body 2a of the first hinge part 1a and the corresponding insert 3a is also in the Fig. 4A to recognize which is a section along the line AA of Fig. 3 shows. The inserts 3a of the first hinge part 1a have in the vertical direction z extending slots 14 which allow adjustment in the vertical direction z, in which case the inserts 3a are guided with their webs 10 at the slots 9 of the intermediate piece 6. An adjustment perpendicular thereto along the first horizontal direction x is possible by an interaction of the projections 7 of the intermediate piece 6 with the groove 8, which is introduced on the underside at a front portion of the base body 2a. That in the Fig. 4A recognizable slot 14 must accordingly have a sufficient lateral play along the first horizontal direction x.

The Fig. 4B shows at the second hinge part 1b, the arrangement of the insert 3b, in which case the insert 3b with the adjusting spindle 4 described above perpendicular to the front of the main body 2b along the second horizontal direction y is adjustable. Relative to the closed door wing results in an adjustability in three mutually perpendicular directions x, y, z, so that with simple means a precise adjustment of the door leaf is possible.

The Fig. 5A and 5B show an alternative embodiment of the door hinge, in which on the underside of the intermediate piece 6 'a wide, arcuate formation 15 is provided, which is guided with a complementary receptacle 16 of the insert 3a in the vertical direction. The molding 15 and the receptacle 16 thus form the second linear guide in the manner of a groove guide. The first linear guide is configured as described above, wherein in the Fig. 5A the groove 8 formed on the main body 2a can be seen.

A comparative consideration of Fig. 5A and 5B It can be seen that the intermediate piece 6 'can be easily formed by forming a sheet, wherein the thickness of the intermediate piece 6' remains approximately the same at different locations. Also, the formation 15 on the underside and the upwardly projecting projections 7 can be formed by sheet metal forming.
