Description

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

A door hinge for aluminum doors with the feature described above is known from practice (overall program Simonswerk "hinge systems for doors, windows and gates," 2005/06, pages 406-409). ( DE202005015780U ). According to the usual embodiment, the belt part to be fastened to the door frame has two belt roller sections, between which a belt roller section of the belt part to be fastened to the door leaf is arranged. The attachment to the extruded profiles of the door frame and the door leaf is usually carried out 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, which runs parallel to the surface of the door leaf in its closed position, adjustable. By this horizontal adjustment of the door can be positioned laterally in the door frame, whereby at both edges of the door an equal distance to the door frame can be adjusted (lateral adjustment). A horizontal adjustment in the direction of the surface normal of the closed door (Andruckverstellung) is not provided. Although door hinges for aluminum doors are tailored to the particular shape of the extruded profiles, in practice the need often arises for at least a slight correction in the sense of a pressure adjustment.

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.

From the DE 610 806 T2 a hinge fitting for door or window with rotating openings is known, which is arranged in an edge flashover of a sash and has adjusting means for positioning the sash relative to the window or door frame. With the help of this adjustment, the squareness of the sash can be adjusted relative to the fixed frame.

Against this background, the invention has for its object to provide a door hinge for aluminum doors, which allows by simple means a Andruckverstellung and has a good stability.

The object of the invention to solve this problem is a door hinge according to claim 1.

It is provided that the through holes are formed as extending in the horizontal direction slots and that the first band part receives at least a pair of setscrews, which are arranged with a horizontal distance from each other and the tightening by wedging in the opposite direction fixation of the first band part cause. Due to the formation of extending in the horizontal direction slots alone no easy to handle Andruckstellung can be realized, since at a release of the corresponding, the through holes of the first hinge part cross-bolts the heavy door without further adjustment means can not be accurately positioned in a simple manner, the Weight of the door also favors a barely controllable tilting.

According to the invention are provided as adjusting means for Andruckverstellung paired threaded pins which cause a tightening wedging in the opposite direction. Although the screws arranged in the oblong holes are loosened, but the setscrews are tightened, no adjustment in the horizontal direction can take place. If, starting from this, one of the two pairs of threaded pins is unscrewed, the wedging is canceled in one direction, so that the first band part can be moved in this direction. Then, when the other set screw of the pair under consideration is screwed in to the same extent, a fixation of the first band part takes place again, but in a different position with respect to the extent of the through holes. By alternating loosening and tightening the paired threaded pins so a Andruckverstellung can be realized, in the field of aluminum doors often already a short adjustment of about one millimeter is sufficient. Without restrictions, however, larger or smaller adjustment paths can be realized.

The adjustment via the threaded pins takes place in such a way that the threaded pins each have a conical tip in order to act when tightened directly on a respective associated web of the extruded profile. The threaded pins are then offset relative to the associated web so arranged that when tightening a respective opposite wedging takes place. In the plan view, according to one of the two paired setscrews left and the other to be arranged on the right of each associated web of the extruded profile.

In order to achieve a sufficiently stable support, the first band part expediently has a first pair in an upper area and a second pair of the described set screws in a lower area. 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.

After performing the Andruckverstellung the arranged in the through holes of the first hinge part screws are tightened, so that a permanent, reliable fixation takes place. The setscrews are each arranged on the side of one of the through holes formed as a slot.

Another aspect of the present invention, which contributes to the achievement of the object according to the invention, relates to the attachment of the first hinge part to the associated extruded profile. Thus, according to this further aspect, the first band part can be fastened to the extruded profile via a carrier, wherein the carrier has threaded bores for the screws, which extend through the through holes of the first band part. In this case, the support is first attached as a separate part to the extruded profile during assembly of the door hinge. In particular, the carrier can be secured by a clamping connection, in which case no holes in the extruded profile must be introduced. Since initially only the carrier must be attached, the handling is particularly simple.

If according to a preferred embodiment, the carrier is releasably fixed, this can still be positioned later.

A further advantage is that a very even force distribution can be achieved by the use of a carrier, so that despite the limited stability of aluminum profiles heavy door leaves can be securely attached.

Only after the fixation of the carrier, the first band part is fastened by means of screws. Since, as described above, a pressure adjustment is provided by at least one pair of grub screws, they can act on associated surfaces of the carrier, whereby an adjustment is realized. For this purpose, the setscrews act directly via a wedge or the like directly on associated webs of the extruded profile. Thus, openings are provided on the support through which extend the setscrews, wherein the set screws each have a conical tip to act when tightened directly on an associated web of the extruded profile. This results in the advantage that in a particularly simple embodiment, a low overall height can be realized.

According to a preferred embodiment of the invention, the extruded profile has a C-groove, on which the door hinge can be fastened. According to an advantageous development then sliding blocks are provided which are used in a first orientation in the C-groove of the extruded profile and engage behind the front portions of the C-groove in a second orientation, whereby the first Band part with the sliding block clamped to the extruded profile can be fastened. If an intermediate carrier is provided, it is held by the sliding blocks, wherein the first band part is fixed to the carrier. The attachment of the band part through the nut is then indirectly via the carrier.

In the first orientation, the sliding blocks can be inserted into the C-groove of the extruded profile, in which case a rotation of the sliding blocks must be effected during assembly. For this purpose, an increased friction and / or a slight fixation can be provided between a thread of the sliding blocks and associated fastening screws by a coating or the like. Known threadlocking coatings are suitable for this purpose. When the sliding blocks are then inserted into the C-groove during assembly of the door hinge and the associated screws are actuated, the sliding blocks are first moved into the second orientation and thus become jammed in the C-slot. In a further rotation of the screw then the increased friction or the slight fixation is overcome, whereby the carrier or directly the first band member is clamped locked.

In the preferred embodiment with a C-groove on the extruded profile, the paired threaded pins, for example, slightly inward with respect to the free ends of the C-profile can be arranged, the threaded pins then when screwing laterally on the ends of the C-groove in each opposite direction act.

The configuration of the second hinge part is not limited within the scope of the invention. According to a preferred embodiment, however, this has a hinge flap, which extends from at least one tape roll portion of the stretched second band portion and is inserted at its free end in a slot of an attachable to an extruded profile receptacle, wherein at the hinge tab at least one adjusting spindle is rotatably supported, which extends into the slot and engages with a threaded portion in an associated thread of the receptacle so that by turning the adjusting spindle, the immersion depth of the hinge flap in the slot is adjustable and wherein the receptacle comprises at least one fixing screw, which is arranged with its screw longitudinal axis at an angle to the hinge tab and presses after tightening directly on the hinge plate and thereby the for a Adjustment by means of the adjusting spindles required clearance eliminated.

The described embodiment of the second hinge part, together with the receptacle described allows a lateral adjustment of the door hinge, which is based on the arrangement of the door leaf in its closed position perpendicular to the Andruckverstellung described above. As a result of the described combination, a very compact door hinge can be provided, which can be fastened with two hinge parts to a respectively assigned extruded profile and adjusted in two dimensions, wherein an extremely compact construction can be realized.

In particular, the fixing screw can also be designed as a threaded pin, which is preferably arranged opposite the hinge tab at an oblique angle. By an oblique arrangement of the limited, available space between the door frame and door leaves can be optimally used, the fixing screw is suitably received in a portion of the receptacle in a thread which extends obliquely relative to the hinge tab.

In order to enable easy manufacture in the manufacture of the door hinge, the receptacle may comprise a base body and an end plate, wherein the slot is formed by a gap between the base body and the end plate. The end plate may for example consist of sheet metal, wherein the base body is preferably a casting. The end plate can be riveted, welded or screwed, for example, with the body, with a riveting from a production point of view is preferred.

If both the door frame and the door have extruded profiles with a C-groove, the receptacle can also be described as described above in connection with the carrier and fastened by sliding blocks.

The invention also relates to an arrangement comprising an extruded profile with a C-groove and the above-described door hinge and a door with a door frame and a door, each having an extruded profile with a C-groove, wherein the door leaf over at least two of the door hinges described is held on the door frame.

As explained above, an adjustment of the door leaf in two mutually perpendicular horizontal directions relative to the door frame is made possible according to a preferred embodiment. In addition, an adjustment in the vertical direction can be provided, for which purpose, for example, a height-adjustable pivot pin between the tape roll sections can be arranged.

The invention will be explained in the following with reference to a drawing showing only one exemplary embodiment. Show it:

Fig. 1

a door hinge according to the invention,

Fig. 2

a horizontal section through a door leaf and a door frame, by a door hinge according to Fig. 1 are connected.

According to the Fig. 1 The door hinge comprises a first hinge part 1a with two spaced-apart tape roll sections 2a and a second hinge part 1b, whose tape roll section 2b is arranged between the two tape roll sections 2a of the first hinge part 1a. The tape roll portions 2a, 2b are connected to each other about a vertical axis rotatably via a bolt assembly 3, which allows in the vertical direction Z, an adjustment of the tape parts 1a, 1b against each other by a few millimeters.

The door hinge shown is intended to be attached on the one hand to a C-groove 4a of a door frame profile 5 and on the other hand, a C-groove 4b of a door leaf frame profile 6. The attachment is made indirectly via a carrier 7 and a receptacle 8. To allow a clamping fixation of the carrier 7 and the receptacle 8, they each have holes 9. In the holes 9 screws 10 are used, each engaging in the thread of an associated sliding block 11. The sliding blocks 11 are shaped so that they can be inserted in a first orientation in the C-grooves 4a, 4b and in an in Fig. 1 illustrated second alignment front portions 12 of the respective C-groove 4a, 4b engage behind. In order to enable during assembly a rotation of the sliding blocks 11 by means of the screws 10, between the internal thread of the sliding blocks 11 and the thread of the screw 10, an increased friction or initially a slight fixation can be provided.

For arranging the first hinge part 1a on the door frame profile 5, the support 7 is first fastened by means of the sliding blocks 11 and the associated screws 10 in the region of the C-groove 4a of the door frame profile 5. In a particularly advantageous manner, a high stability and a uniform force distribution can be achieved, so that even with heavy door leaves damage or bending of the door leaf frame profile 5 can be excluded. After attachment of the carrier 7, the first band part 1a is screwed with screws 10 to the carrier 7 as an intermediate element. The screws 10 provided for this purpose pass through through holes of the first hinge part 1a, which are designed as elongated holes 13 extending in the horizontal direction Y. The side of the uppermost and the lowermost elongated hole 13, a pair of threaded pins 14 is received in each case, which extend through openings 15 of the carrier 7 therethrough.

How the particular Fig. 2 can be seen, the threaded pins 14 have a conical tip, wherein the threaded pins 14 are arranged slightly offset inwardly with respect to the front portions 12 of the C-groove 4a. When screwing the threaded pins 14, these act laterally on the front portions 12 via their conical tips. If one of the two setscrews 14 is released starting from a middle position of the first band portion 1a and tightened setscrews 14, the fixation of the first band portion 1a is released, so that the first band part 1a in the door thickness direction Y (Andrückverstellung) can be moved. Subsequently, when the other threaded pin 14 is further screwed in a corresponding extent, the first band portion 1a is fixed in a different horizontal position, wherein by a mutual loosening and tightening the setscrews 14, a free positioning of the first band portion 1a can be realized in a predetermined adjustment range of, for example, 1 mm.

Since the first band part 1a receives two pairs of setscrews 14, uncontrolled tilting during adjustment can be avoided.

The second band part 1b comprises a band tab 16 which extends away from the associated band roller portion 2b and is inserted with its free end into a slot 17 of the receptacle 8. The receptacle 8 is formed from a base body 18 and an end plate 19 connected to the base body 18, preferably by riveting, which are in the Fig. 1 is shown separated from the main body 18 for clarity. A space between the base body 18 and the end plate 19 forms the slot 17 extending in the vertical direction.

Of the Fig. 1 It can be seen that at the hinge tab 16 two adjusting spindles 20 are rotatably supported by a positive connection, wherein the adjusting spindles 20 extend into the slot 17 and engage with a threaded portion so in an associated thread of the receptacle 8 that by turning the adjusting spindles 20th the immersion depth of the hinge strap 16 in the slot 17 is adjustable. By actuating the adjusting spindles 20, a lateral adjustment of the door hinge is thus made possible in a horizontal direction X. So that the game required for the setting does not adversely affect the use of the door hinge after its assembly, the receptacle 8 comprises two fixing screws 21, which are also formed in the illustrated embodiment as threaded pins. The fixing screws 21 are arranged with their screw longitudinal axis at an angle to the hinge tab 16 so that they press after tightening directly on the hinge tab 16, whereby the clearance required for the adjustment by means of the adjusting spindles 20 is eliminated.

According to the illustrated embodiment, the fixing screws 21 are arranged obliquely relative to the hinge tab 16 and used accordingly in an obliquely opposite the hinge tab 16 extending portion 22 of the receptacle 8. The described oblique arrangement of the fixing screws 21, a particularly low height of the receptacle 8 can be achieved on the door leaf frame profile 6.
