The adjustable insert may be formed, for example, as a receptacle for a hinge flap. Alternatively, the door hinge may be provided for a concealed arrangement between the door leaf and door frame, wherein the hinge parts are insertable into recesses of the door frame and in the narrow side of the door leaf and are interconnected by two mutually rotatable hinge bracket.

A door hinge with two hinged hinge parts, wherein one of the hinge parts has a base body for attachment to a door frame or a door leaf and at least one relative to the base body in two directions adjustable insert, is from the EP 1 308 592 A2 known, wherein the two hinge parts each have a base body, which above and below the two hingedly interconnected hinge bracket has two opposite the base body adjustable inserts. The hinge brackets are held on the inserts, wherein on each insert one of the hinge brackets is rotatable and the other hinge bracket is rotatably and movably received along a guide slot. At one of the band parts, the inserts are adjustable relative to the base body in the vertical direction, wherein in the vertical direction a groove guide and acting on the inserts, supported on the base adjusting excursion are provided. At the other band part is an adjustment in two realized perpendicular to each other horizontal directions, wherein an adjustment is made possible parallel to the front of the band parts by slots. With the appropriate adjustment, the position of the closed door leaf can be adjusted perpendicular to the door leaf surface. By this adjustment, the outer surface of the door with respect to the mirror surface of a frame can be adjusted, whereby the pressure exerted on a door seal pressure is changed. The corresponding horizontal adjustment is therefore also referred to in practice as Andruckverstellung. An adjustment perpendicular to the front of the corresponding band member is made possible by an adjusting spindle, which can be adjusted to the frame on both sides by this adjustment in a closed door leaf remaining gap. The corresponding adjustment is therefore referred to in practice as a lateral adjustment.

Another hinge with two hinged band parts, wherein one of the band parts has a base body for attachment to a door frame or a door leaf and at least one relative to the base body in two directions adjustable insert is from the DE 10 2009 038 955 A1 known, wherein a lateral adjustment via an adjusting spindle and a Andruckverstellung perpendicular thereto via at least one slot. The adjusting spindle is arranged between a front plate and a back plate. In order to allow additional adjustment in a further horizontal direction, at least one further clamping plate or intermediate plate is necessary. The known door hinge is structurally relatively complex and requires a variety of parts to be bolted together.

A door hinge according to the preamble of claim 1 is known from EP 2 390 446 A1 known.

Against this background, the invention has for its object to provide a door hinge with two hinged hinge parts, in which 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 in that the insert relative to the intermediate piece along a second linear guide is displaceable in a second direction, and that a fixing means for clamping locking a front portion of the body, the intermediate piece and the Take action.

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, the straight guides provided for the adjustment can be formed in a simple manner 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 second linear guide each having at least one projection in a associated groove engages 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. In 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.

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. The fixing means may for example be a screw which engages in a threaded piece, wherein by tightening the screw of the insert and the intermediate piece are pulled by clamping the threaded piece against the body.

For the further embodiment of the door hinge arise in the context of the present invention, various possibilities. According to a preferred embodiment, it is provided that two hingedly cooperating hinge bracket are provided as the connection of the hinge parts, wherein the hinge parts each have the main body and two inserts and wherein the inserts each one of the hinge bracket rotatable and the other hinge bracket rotatable and along a guide slot of the inserts are slidably received.

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 also be created 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 shown, wherein the two band parts 1a, 1b each have a base body 2a, 2b and in each case 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 lower side formations which form a first linear guide with assigned formations on the basic body 2a and with associated formations on the insert 3a a second linear guide.

In the illustrated embodiment, the intermediate piece 6 on its upper side two projections 7, which in a along the first horizontal

Direction x extending groove 8 engage 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, wherein 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 results, for connecting the two band parts 1a, 1b, the hinged to the rotation axis D hinge bracket 5 are provided, wherein the hinge bracket 5 rotatably on the inserts 3a, 3b one of the band parts 1a, 1b and the inserts 3b, 3a of the other Band part 1 b, 1 a slidably received along a guide slot 13. The Fig. 3 shows in this connection a further development of such per se known arrangement in which two guide slots 13 are arranged on each insert 3a, 3b, 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 inventive arrangement of the intermediate piece 6 between the main 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 on the second hinge part 1 b, the arrangement of the insert 3b, in which case the insert 3b with the adjusting spindle 4 described above is perpendicular to the front of the main body 2b along the second horizontal direction y 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 at the bottom of the intermediate piece 6 'has a wide, arcuate shape 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.
