Description

The The invention relates to a door hinge for aluminum doors with a first band part and a second band part, each at least having a tape roll portion and the tape roll portions are rotatably connected to each other about a vertical axis, wherein the first band part for attachment to an extruded profile has through holes.

One hinge for aluminum doors with the feature described above is known from practice (Gesamtprogramm Simonswerk "Tape Systems for doors, windows and Gates ", 2005/06, pages 406 to 409). According to the usual embodiment, the on the door frame to be fastened tape part two tape roll sections on, between which a tape roll portion of the door to be fastened to the hinge part is arranged. The attachment to the extruded profiles of the door frame and the door is usually done by screws, which engage through the profile in previously inserted insertion pieces. The known door hinges are two-dimensional on the one hand in height and on the other hand a first horizontal direction parallel to the surface of the door leaf in its closed Position runs, adjustable. Through this horizontal adjustment, the door can be in the Door frame sideways be positioned, whereby at both edges of the door leaf to an equal distance the door frame can be adjusted (lateral adjustment). A horizontal adjustment in the direction of the surface normal of the closed door leaf (pressure adjustment) is not scheduled. Although door hinges for aluminum doors up the particular shape of the extruded profiles are matched results in practice often the need at least a minor one To allow correction in the sense of a Andruckverstellung.

From the DE 69 39 409 U a door hinge for metal hollow sections is known, which comprises a first hinge part and a second hinge part, which are connected to tape roll sections about a vertical axis rotatably connected to a hinge pin. In order to arrange all fasteners concealed and yet to ensure a secure fixation of the band parts, the band parts each comprise a slanted threaded pin which applies to clamp on the inner edge of an associated bore of the hollow profile during assembly to a hollow profile with a conical tip. A position adjustment of the door hinge is not provided.

In front In this background, the invention is based on the object hinge for aluminum doors, which by simple means a Andruckverstellung allows a good stability having.

outgoing from a door hinge with the features described above, the object is achieved according to the invention solved, that the through holes as formed in the horizontal direction elongated holes are and that the first hinge part at least a pair of grub screws picks up, which are arranged with a horizontal distance to each other are and when tightened by a wedging in the opposite direction cause a fixation of the first band portion. Through the training of extending in the horizontal direction slots alone can not yet easily manageable Andruckstellung be realized because at one Solve the corresponding, the through holes of the first hinge part sweeping screws of the heavy door without further adjustment means not precisely positioned in a simple manner can be, with the weight of the door also a barely controllable Tilting favors.

According to the invention are as Adjusting means for the Pressure adjustment provided in pairs threaded pins, which when tightened a wedging in the opposite direction cause. Although the screws arranged in the oblong holes solved, but the setscrews are tightened, can not be adjusted in horizontal direction. If one of them starts in pairs arranged threaded pins is unscrewed, the wedging lifted in one direction, leaving the first band part in that direction can be moved. If then the other grub screw of the considered Couple to the same extent is screwed in, a fixation of the first band part, but in a different position in terms of extension the through holes. By alternately releasing and tightening the paired threaded pins can so a Andruckverstellung be realized, wherein in the field of aluminum doors often already short adjustment of about one millimeter is sufficient. Without restrictions but are also larger or smaller adjustment possible.

The Adjustment over the grub screws can for example be made such that the Grub screws each have a conical tip to the Tightening directly on a respective associated web of the extruded profile to act. The grub screws are then opposite the associated web in such a way staggered arranged that when tightening a respective opposite Wedging takes place. In the plan view is corresponding to one of both a pair of forming threaded pins on the left and the other on the right to arrange from a respective associated web of the extruded profile.

In order to achieve a sufficiently stable support, the first band part is more expedient example, in a top portion on a first pair and in a lower portion a second pair of threaded pins described. In such an embodiment, a controlled tilting of the axis of rotation between the strip parts can also take place to a certain extent for fine adjustment by setting a different pressure adjustment on the first pair and on the second pair.

To the implementation the Andruckverstellung are in the through holes of the tighten the first part of the belt so that a permanent, Reliable fixation takes place. Appropriately, are the screws each side of one of the elongated hole formed through holes arranged.
