DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The following is a detailed description of example embodiments of the invention depicted in the accompanying drawing. The example embodiments are presented in such detail as to clearly communicate the invention and are designed to make such embodiments obvious to a person of ordinary skill in the art. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention, as defined by the appended claims.

(9) FIG. 1 presents a door hinge according to the invention, in an installed state. The door hinge comprises a first hinge part 1 and a hinge bracket 3, which is connected to the first hinge part 1 to be pivotable about a rotational axis 2. The hinge bracket 3 is connected to a second hinge part 4.

(10) The hinge bracket 3 has an angled mounting section 3a, which is forcibly guided in a first direction x and is lockable in place on a receiving block 5. The receiving block 5 itself is adjustable in a second direction y in the second hinge part 4.

(11) In the installed state shown, the first hinge part 1 is embedded in an associated recess in a door leaf 6. The door leaf 6 comprises a door leaf main body 6a and a door rabbet 6b protruding therefrom, on the narrow side. The first hinge part 1 is inserted via a main body 1a into the door leaf main body 6a and comprises a projection 1b, which extends into the door rabbet 6b. The projection 1b is formed by an upper segment and a lower segment which engage around the hinge bracket 3 on the top side and on the bottom side, respectively. The rotatable connection between the first hinge part 1 and the hinge bracket 3 is situated in the projection 1b, and so the rotational axis 2 extends through the projection 1b and the door rabbet 6b.

(12) The hinge bracket 3 comprises a connecting section 3b, which is shaped as a circular arc in the horizontal section represented in FIG. 2 and which connects the mounting section 3a to the rotatable connection to the first hinge part 1. In the closed state of the door hinge, which is shown in FIG. 2, the connecting section 3b initially extends through the projection 1b in the direction of the main body 1a of the first hinge part 1 and, there, passes through an associated hollow space. Next, the connecting section 3b extends through the door gap 10 situated between the door leaf 6 and the door frame 7 and transitions, at a right angle, into the mounting section 3a. Due to the positioning of the rotational axis 2, it is possible to pivot the door leaf 6 around the outer surface of the door frame 7 in a collision-free manner. The second hinge part 4 is inserted into an associated recess in the door frame 7. Furthermore, a jamb rabbet 7a is provided on the inside of the door frame 7 and interacts with an associated recess 6c of the door leaf.

(13) The mounting section 3a is locked in place on the receiving block by three associated clamping screws 8, which pass through slots, and are adjusted in the first direction x (pressing direction) by use of two cams 9.

(14) It should be clear from FIG. 3 that the receiving block 5 has a stepped recess having a back surface 5a and two step edges 5b. The flat mounting section 3a is inserted into the recess to be flush with a front side 5c of the receiving block 5 and rests against the step edges 5b in a form-locked manner.

(15) It also should be clear from the cross-sectional view that the receiving block 5 is forcibly displaceable, in a form-locked manner, in the second direction y on an inner surface of a first receiving element 11a which, in the exemplary embodiment, forms the second hinge part 4. The receiving block 5 is thereby adjustable in this direction by spindle drive 12.

(16) FIGS. 4 and 5 depict a three-dimensionally adjustable door hinge and correspond to the representations of the two-dimensionally adjustable door hinge in FIGS. 1 and 3. In contrast thereto, the second hinge part 4 comprises a second receiving element 11b having a second inner surface, in which an intermediate piece 13 is situated to be displaceable along a third direction z. The receiving block 5 is forcibly guided on the intermediate piece 13 in the second direction y. In FIG. 4, it is evident in the lower region of the second hinge part that the intermediate piece 13 can be moved in the third direction z by a wedge-assisted adjusting element 14. In addition, locking screws 15 are provided, which can pass through associated slots in the intermediate piece and lock the intermediate piece into place by clamping the intermediate piece against the second receiving element 11b in the third direction z.

(17) In addition, a cover plate 16 is shown above the hinge bracket 3 on the second hinge part 4. The cover plate conceals and protects the mechanisms and adjustment settings lying behind it. A corresponding cover plate 16 also can be used in the lower region of the second hinge part and in the embodiment, according to FIGS. 1 to 3. The fastening of the cover plate 16 passes through the intermediate piece 13 through a slot and is connected to the second receiving element 11b.

(18) The wedge-assisted adjusting element 14 is apparent in detail in the cross-sectional view of FIG. 5. The wedge-assisted adjusting element is formed by a wedge piece 14a, which is displaceable in the second direction y by a spindle drive 14b. The wedge-shaped piece 14a bears against an oblique wedge-shaped surface on an associated wedge-shaped surface of the intermediate piece 13.

(19) The components of a door hinge system according to the invention are shown in FIG. 6. The door hinge system includes a first hinge part 1 having a hinge bracket 3, which is connected so as to be rotatable about a rotational axis 2. The hinge bracket 3 comprises an angled mounting section 3a on its end facing away from the first hinge part 1. The door hinge further includes a receiving block 5, on which the mounting section 3a is forcibly guided in a first direction x and is fastened to be locked in place. In addition, a fastening device is provided, in which the receiving block 5 is adjustable in a second direction y.

(20) The fastening device alternatively comprises a first receiving element 11a for fastening on a door frame or on a door leaf, which provides a first inner surface, on which the receiving block 5 can be directly mounted in a sliding fit, to form a forced guidance in the second direction y.

(21) Alternatively, the fastening device comprises a second receiving element 11b, in which an intermediate piece 13 is situated to be displaceable along a third direction z. The intermediate piece provides a second inner surface, on which the receiving block 5 can be mounted, in order to form a forced guidance along the second direction y.

(22) As shown, the first, the second, and the third direction x, y and z, respectively, are each perpendicular to each other. In this case, the first direction x is referred to as the pressing direction, the second direction y is referred to as the lateral direction, and the third direction z is referred to as the vertical direction.

(23) As will be evident to persons skilled in the art, the foregoing detailed description and figures are presented as examples of the invention, and that variations are contemplated that do not depart from the fair scope of the teachings and descriptions set forth in this disclosure. The foregoing is not intended to limit what has been invented, except to the extent that the following claims so limit that.
