Description

The invention relates to a door hinge for patch mounting on hollow chamber systems, comprising a first band portion and a second band portion, each having at least one band reel portion and are connected to each other at the tape reel sections about a vertical axis of rotation, wherein the first band portion extending from its at least one tape reel section extending away hinge strap having a flat free end and provided for the arrangement between the free end and a frame profile contact element and wherein the hinge tab and the at least one tape roll portion of the first hinge part are formed from a piece of sheet metal. The door hinge is intended in particular for doors in which the frame and / or the door leaf have a hollow-chamber profile frame, which is preferably formed from aluminum, steel or stainless steel.

The fastening of the door hinge takes place laterally on the narrow side of the door leaf and on the reveal side of the frame, in which case the parts intended for fastening such as fastening screws or the like are concealed in the gap between the door and frame, while the tape roll sections on one side of the door from this lateral gap are led out. In order to fasten the door hinge to hollow chamber profiles and thereby achieve a high load capacity, the hinge parts of the door hinge may each have an insertion piece, which is insertable into a cavity within the frame profile of the frame or door.

A door hinge for patch mounting on hollow chamber systems is from the DE 100 06 868 A1 known.

The DE 297 19 468 relates to a door hinge with a first and a second hinge part, which are rotatably connected to each other via an axis. The first hinge part has a hinge flap, which is connected to a contact part, wherein the contact part is attached to the outside of the frame profile. Furthermore, an adjusting spindle is provided, which is aligned perpendicular to the axis of rotation and is held positively in a recess on a first side and at a second end has a thread which engages in a threaded hole of an angled portion of the contact element. In a closed door the two band parts are usually arranged at an angle of 90 °.

From the DE 103 55 850 A1 a device for fixing a frame part of a door hinge to a door frame is known, wherein the door hinge is inserted from the inside into the frame. The door hinge is accordingly only suitable for frames made of sheet metal, which have a thin-walled jacket made of a dimensionally stable material, in particular sheet metal. The attachment of the wing-side hinge part is not described.

From the DE 26 10 173 A1 as well as from the GB 2 463 116 A are more door hinges known which are placed from the outside and form an angle of 90 ° in a closed state between the band parts.

For door hinges, it is advantageous if they are adjustable to some extent, so that during assembly accurate alignment is possible. By a height adjustment in the vertical direction, the gap at the top and bottom of the door can be adjusted. Thus, the gap on the underside of the door leaf can be set to the smallest possible extent, in which still a reliable, jam-free movement of the door leaf is possible. In general, by a vertical Adjustment of the door leaves are subsequently raised, if this is set during use to a certain extent.

In order to avoid jamming during the pivoting movement of the door hinge and to insert a door leaf symmetrically and flush in a door frame, further horizontal adjustments are known. By means of an adjustment in a horizontal direction, the door leaf can be moved in the closed position parallel to its front surfaces in order to set the lateral gap on both longitudinal edges of the door leaf. The horizontal adjustment described is also referred to as a side adjustment accordingly.

By a relative to the closed position of the door to perpendicular horizontal adjustment can be made in the direction of the thickness of the closed door leaf. By such an adjustment, the door can be further moved into the opening formed by the frame in or out of this. Depending on the specific embodiment of the hollow chamber system can be achieved between the door and the door frame on the inside and / or outside of the door a continuous, flush transition. In the case of hollow chamber systems, it is further customary to form overlappings between the door leaf and the door frame by means of a step shape, in which case a seal which can be compressed in the direction of the thickness of the door is then used in this overlapping area. The described adjustment, the compression of this seal can be adjusted, which is why the adjustment in this second horizontal direction is also referred to as Andruckverstellung.

Door hinges for patch mounting on hollow chamber systems with the features described above, which have a vertical height adjustment and a horizontal side adjustment, are known in practice

(Complete program Simonswerk " Hinge systems for doors, windows and gates ", 2005/06, pages 409 to 412 ). According to the usual embodiment, the band part to be fastened to the door frame has two band roll portions, between which a band roll portion of the band part to be fastened to the door leaf is arranged. The attachment to the extruded profiles of the frame frame and the door leaf is usually carried out by means of screws which engage through the frame profile in previously inserted insertion pieces or directly into the thread of the frame profile, if this alone has sufficient structural strength. Since the band parts are mounted on frame profiles, a compact design is necessary. A Andruckverstellung is not realized in particular because of the small available space in the known door hinges for patch mounting.

Against this background, the invention has for its object to provide a door hinge for patch mounting on hollow chamber systems, which allows simple means precise adjustment in the horizontal direction. In particular, a pressure adjustment should be provided in a compact design of the door hinge.

Starting from a door hinge for patch mounting on hollow chamber systems with the features described above, the object is achieved in that the hinge tab is positionable in the plane of the free end and perpendicular to the axis of rotation relative to the contact element by at least one adjusting spindle, wherein the adjusting spindle a first side is positively held in a recess of the free end and on a second side has a thread which engages in a threaded hole of an angled portion of the abutment element, and wherein the adjusting spindle for rotation on the second side has an end-side approach for a tool. The second side of the at least one adjusting spindle is at an open door directly and easily accessible, whereby an easy handling is achieved. The abutment element can have, for example, an L-shape with a contact surface for the free end with the section bent perpendicularly from the abutment surface.

Conveniently, the approach for a tool is formed within the diameter of the thread, so that the end-side approach sunk in a part of the adjustment or over the entire adjustment within the associated threaded hole, whereby a sufficient travel can be provided with the smallest possible design. As an approach, for example, a simple slot or a Phillips be provided. Furthermore, the approach can also have the shape of a square socket, a hexagon socket, a Torx or a similar positive-locking receptacle to be rotated with a complementary trained tool.

The adjusting spindle may in particular have the form of a screw, wherein on the first side of the adjusting spindle, a thickening in the form of a head is provided, which is held in a T-shaped recess of the free end of the hinge strap. The second side of the spindle then has a thread with a continuous cylindrical outer surface, however, in contrast to a conventional screw, the above-described end attachment for a tool is formed.

The inventive adjustment in a horizontal direction can be realized with only one adjusting spindle, in which case, however, only a punctual support takes place, so that a significant tilting can occur if no measures counteracting tilting such as the formation of additional guides is provided. According to a preferred embodiment is therefore intended that the hinge tab with respect to the contact element by two adjusting spindles, which are arranged parallel to each other at a distance adjustable. By alternating actuation of the adjusting spindles, a uniform and precise adjustment can be made over a wide range. Any inclinations or jamming can be compensated by the operation of one of the two screws.

The first hinge tab and the at least one tape roll of the first hinge part are formed from a piece of sheet metal, wherein the recess for the positive reception of the adjusting spindle and holes for screws by drilling, milling or punching can be formed. The tape roll portion of the first tape part is normally formed by bending or rolling of the sheet, so that overall the tape tab and the tape roll portion of the first tape part are made continuous and one piece. In addition to low costs and a simple production starting from sheet metal as a base material, the first band part is characterized by a particularly high strength. If the second band part according to a preferred embodiment of the invention comprises two spaced apart belt roller sections, these belt roller sections can also be formed, each with adjacent hinge tab pieces in a corresponding manner from a piece of sheet metal.

The profiles for hollow chamber systems of doors often have steps that can also be used for the arrangement of seals. The hinge flap is then suitably bent in accordance with the course of the frame profile, including the band tab of the first hinge part between the flat free end and its tape roll portion is bent, that is angled. Particularly useful is an S-shape with two right angles. The components of the second hinge part are to be shaped accordingly.

In a manner known per se, an insert piece insertable into the frame profile can be provided for fixing the band parts to the associated frame profiles. Thus, according to a preferred embodiment for the frictional attachment of the first hinge part to the associated frame profile insertable into the frame profile insert and screws used, the mounting screws in the assembled state at least pass through holes of the contact element and engage in internal thread of the insertion piece. The insertion piece can be dimensioned so that it at least substantially fills a chamber of the frame profile in the door thickness direction, so that the insertion piece is held in this direction without play or only with a small clearance. In order then to allow adjustment by means of at least one adjusting spindle, it is expediently provided that the fastening screws in the installed state penetrate through holes of the contact element and the free end, wherein the holes of the contact element and / or the free end are formed as elongated holes which are parallel extend to the at least one adjusting spindle. Alternatively, it would also be conceivable that only the contact element is directly connected to the insertion piece, in which case the free end of the hinge strap is fixed only via a direct connection with the contact element. However, in such an embodiment, the stability is at least reduced to some extent.

In addition to the Andruckverstellung invention, the door hinge preferably also adjusting means for vertical adjustment parallel to the axis of rotation and / or means for lateral adjustment. A particularly simple lateral adjustment can be achieved in that the first hinge part has at least one spacer plate insertable between the free end of the hinge strap and the abutment element. Usually will a set with at least two spacer plates held, which may also have a different thickness. To set a desired distance in the side adjustment during installation a correspondingly thick spacer plate, if present, inserted or several equal or different thickness spacer plates can be combined. Depending on the design of the door hinge is alternatively also a side adjustment by spacer plates or other adjustment options on the second band part into consideration.

In order to enable an adjustment in the vertical direction, a separate element can be mounted below the second hinge part according to the known from practice, this separate element then having an adjustable support means with which the second hinge part is raised and lowered.

According to a preferred embodiment of the invention, the second hinge part has a auflegbare on a frame profile mounting plate. This mounting plate, for example, record means for adjustment, in particular means for vertical adjustment. Thus, a block with a threaded pin for support may be provided on the mounting plate, wherein the formed as a separate component block is positively held with a sliding seat in a guide recess of the mounting plate and is limited under the action of the components of the second strap part on the underside of a stop surface , This results in the advantage that the mounting plate can be formed in a particularly cost-effective manner from sheet metal or other flat material, while only the block requires increased production costs.
