Description

The invention relates to a door hinge with a first hinge part, a hinged around an axis of rotation pivotally connected to the hinge part and a hinge part connected to the hinge part. Such a detachably connected to the second band part band tab - which is usually formed flat - is also referred to as a so-called hinge tab.

Such a door hinge is off EP 2 476 836 A1 known.

To fasten a door leaf in a door opening, the first hinge part is usually fastened to the hinge leaf or hinge flap, which is pivotable thereon, on the door leaf or on the door frame. The second hinge part for receiving the hinge strap is then held in the opposite part (door frame or door leaf). Usually, this assembly is done separately. To connect the hinge plate is inserted into the receiving device of the opposite band part and fixed there.

A common embodiment is that two clamping plates are provided in the receiving band part, between which the band tab can be inserted and locked by clamping the two clamping plates against each other. This clamping arrangement may additionally contain an adjusting mechanism.

In this embodiment, however, is a disadvantage that sufficient holding forces for the application of the part of the hinge strap, which is inserted between the two clamping plates, must be very large and therefore the Tape tab must dive very deep into the receiving device. Furthermore, an adjustment in more than one spatial direction is very expensive to implement.

Against this background, the invention has for its object to provide a stable door hinge with the above features, the second hinge part requires only a small installation height of the door frame or on the door leaf. Furthermore, an advantageous multi-dimensional adjustment of the door hinge should be provided.

The object of the invention and solution of this problem is a door hinge according to claim 1 and a door hinge system according to claim 15.

According to the invention, the hinge bracket has an angled abutment section, which is forcibly guided and lockable on a receiving block in a first direction. The receiving block is in turn arranged adjustable in a second direction in the second band part. Angled means that a not belonging to the contact portion, adjacent thereto region of the hinge bracket with the contact portion forms an angle. This can be conveniently realized by bending a block-shaped blank to an L-shape. However, other forms - such as, for example, by casting metal or (extruded) pressing profiles - can be used to implement the inventive concept. The first direction, in which the abutment section is positively guided, is expediently in the plane of the abutment section. The adjoining, angled portion is preferably approximately perpendicular thereto. Due to the positively guided attachment of the abutment section to the receiving block, the attachment of the hinge strap to the second band part is advantageously combined with a first adjustment. One Most of the forces are already absorbed by the positive guidance, so that the attachment and locking must be effective only in the first direction. The receiving block is arranged as a whole - and thus also the connected thereto hanger - adjustable in the second direction.

In a preferred embodiment, the receiving portion is formed flat. This not only has the advantage that the hinge bracket can be made particularly cost-effectively from the usual sheet-like materials or (extruded) press profiles already used in hinge flaps, but in conjunction with the angled abutment section, a particularly shallow installation depth can also be achieved. Usually, the two band parts are each inserted into corresponding recesses on the door frame and door leaf. The door leaf according to the invention may preferably be formed such that the flat abutment portion extends approximately parallel to the front surface of the door frame or the door leaf enclosing the receiving opening of the second hinge part. Thus, the hinge bracket extends in the assembled state only in the recess by the thickness of the flat contact section, so that particularly flat installation is possible here.

In a particularly preferred embodiment, the receiving block has a step-like recess, in which the flat receiving portion is inserted flush and at the step edges of the receiving portion to form a sliding fit positively. The recess has a back surface which corresponds substantially to the size of the receiving portion. At this back surface are perpendicular to the step edges, which extend to a front surface of the receiving block. Preferably, the receiving portion is free of play between the two step edges and is guided linearly on these.

Preferably, the receiving portion is locked by clamping screws on the receiving block. The clamping screws pass through expediently elongated holes of the receiving portion and are screwed into internal thread on the receiving block. The arranged at the outer end of the clamping screws screw head is clamped by tightening the clamping screws against the receiving block and clamps the receiving portion arresting. Preferably, the heads of the clamping screws are received sunk in the receiving portion.

As an alternative to a manual adjustment of the receiving portion by a mechanical adjustment - preferably an eccentric - be adjustable in the first direction. Thus, adjustment and displacement mechanics are independent of each other. By the eccentric can be done a very precise adjustment of the door hinge in the first direction. The eccentric is advantageously in the same direction as the clamping screws - that is, from the front of the second band part - operated.

In particular, the hinge bracket has a connection section arranged between the contact section and a rotatable connection with the first hinge part. The rotatable connection can be provided for example by a rotation axis. In this case, the connecting section preferably has a right angle with respect to the contact section.

In a preferred embodiment, the contact section projects beyond the connecting section in the direction of the axis of rotation. As a result, for example, operating elements - for example the clamping screws or an eccentric for adjusting the door hinge in the first direction - can advantageously be arranged above and / or below the connecting section. As a result, are These are particularly easy to access. Furthermore, the contact section represents a larger lever for the transmission of tilting moments.

In a preferred embodiment, the first hinge part has a protrusion projecting over a base body for arrangement in a fold of a door leaf or a door frame. The axis of rotation runs through this projection - and thus in the installed state by the fold of the door leaf. In a preferred embodiment it is provided that the connecting portion is formed in a circular arc, in particular semicircular. As a result, the door hinge according to the invention can be arranged concealed between the door frame and the door leaf.

In a fold, it is a stepped over the approximately rectangular elongated basic cross section of a door leaf (or a door frame) protruding paragraph. This serves to seal in the closed state of the door, the door gap, which results between the door leaf and the door frame, and conceal. In the design of the door hinges for rebated doors, however, there is always the disadvantage that they can be concealed only with increased effort. In order to prevent a collision of the door rebate with an abutment surface on the associated door frame during an opening movement, the axis of rotation is displaced into the fold. However, this is not possible in a conventional door hinge with hinge parts of approximately box-shaped receiving bodies, which can be inserted into the narrow side of the door leaf and the associated inner surface of the door frame. For this purpose, in the preferred embodiment of the door hinge a projection is provided to be arranged in the door rebate. This is designed so that it receives the pivot axis of the door hinge. For this purpose, the pivot mechanism is conveniently held in the projection. In particular, the projection may have an upper and a lower portion, which engage around the hinge bracket on the upper and lower sides and hold the axis of rotation for rotatable connection with the hinge bracket.

The circular arc-shaped connecting portion of the hinge bracket extends in the closed state of the door hinge first by the projection of the first hinge part and by the box-shaped receiving body. Both advantageously have an adapted recess for this purpose. Subsequently, the connecting section passes through the door gap and merges on the opposite side in the contact section. Thus, the equipped with a simple hinge strap door hinge is suitable to be used concealed on a rebated door.

In a particularly preferred embodiment, the receiving block is adjustable by a spindle drive in the second direction. This second direction preferably extends perpendicular to the hinge axis and to the first direction. Thus, the spindle drive can be arranged approximately parallel to any existing clamping screws for fixing the abutment portion. Both elements are then from the same direction - from the direction of the door gap - accessible and operable.

In a preferred embodiment, the second hinge part has a receiving element for attachment to a door frame or a door leaf with an inner surface. The receiving block is forcibly guided in the receiving element in a sliding seat in the second direction. The receiving element is usually inserted in the assembled state in an associated recess.

To form the sliding seat, the receiving block rests directly against the inner surface with a peripheral surface perpendicular to the second direction. Thus, the positive guide forming sliding seat can be made without further components.

In a preferred embodiment of the receiving block is on all sides, in particular without interruption circumferentially on the inner surface.

In a further preferred embodiment, an intermediate piece is displaceably arranged along the third direction in the receiving element and the receiving block is forcibly guided on the intermediate piece in a sliding fit in the second direction. In this case, the receiving block can also have direct contact with at least parts of the inner surface for the partial provision or support of the positive guidance in the second direction. In this way, a three-dimensionally adjustable door hinge can be made particularly simple, which does not require a deep space.

Conveniently, the intermediate piece is adjustable with a wedge adjustment in the third direction. The wedge adjustment is formed by a wedge piece, which is linearly displaceable by means of a spindle drive and is supported with an associated wedge surface of the intermediate piece. The wedge adjustment is self-locking by the use of a spindle drive. Therefore, the door hinge does not necessarily require locking means in the third direction. Preferably, the wedge adjustment is used for height adjustment, so that the weight of the door hinge and / or the door attached thereto acts as a restoring force opposite to the force caused by the wedge adjustment force. Alternatively or additionally, a second wedge adjustment may also be provided on the opposite side. These also allows a more flexible use of the door hinge regardless of the direction of impact of the door leaf.

The invention also encompasses a door hinge system for providing a door hinge with a first hinge part and with a hinge strap pivotally connected to the first hinge part about a pivot axis. In this case, the hinge bracket at its end facing away from the first band part on an angled abutment portion. The door hinge further comprises a receiving block, on which the abutment portion is forcibly guided in a first direction and lockable. Furthermore, a fastening device is provided, in which the receiving block is adjustable in a second direction. The fastening device optionally has a first receiving element for attachment to a door frame or a door leaf with a first inner surface on which the receiving block in a sliding fit directly and is forcibly guided in the second direction or the fastening device has a second receiving element for attachment to a door frame or a door panel having a second inner surface in which an intermediate piece is slidably disposed along a third direction and the receiving block is forcibly guided at the intermediate piece into a sliding seat in the second direction. In particular, can be produced in this way door hinges according to the preceding claims. Due to their modular design, it is possible to use the same basic components for the production of both two- and three-dimensionally adjustable flat-building door hinges. The adjustment options can be particularly easily adapted to the requirements of the installation by the variable nesting of different mutually perpendicular positive guides.
