Description

The invention relates to a door hinge for aluminum doors according to the preamble of claim 1. Such a door hinge is made EP 0 919 686 A2 known.

Door hinges for aluminum doors are known in practice ( Complete program Simonswerk "Tape systems for doors, windows and gates", 2005/06, pages 406 to 409 ). 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 the height and on the other hand in 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). In the simplest case spacers are placed for lateral adjustment. However, the setting is then very complex and can only be done in discrete steps. Alternatively, it is known to provide a tape recording that allow continuous adjustment by means of adjusting spindles. The known designs are complex in their construction and require a large amount of space. From the EP 2 072 727 A1 a door hinge for aluminum doors with a first band part and a second band part is known, each having a band roll portion and which are connected to the band roll portions rotatable about a vertical axis with each other. Starting from the tape roll sections extends at both hinge parts in each case a hinge plate, which is screwed for mounting on a hollow profile in each case on an associated holding plate, wherein the holding plate is inserted in the manner of a sliding block in a C-groove of the associated profile. The hinge tabs are placed in the plan with their ends each plan on an associated plate and secured by screws, at the same time there is a clamping fixation on the bent end portions of the C-groove. An exact positioning of the door hinge is not possible, whereby the construction height of the patch on the holding plates ends of the hinge flap is considerable. The gap between the door leaf and the door frame must be selected to be correspondingly large. A generic door hinge for aluminum doors is from the EP 0 919 686 A2 known. The door hinge is designed for a patch mounting, in which not only the tape roll sections, but also the adjoining tape parts are visible. The door hinge comprises a hinge flap, which is held by an adjusting spindle in a receptacle, wherein a locking is effected by a fixing screw. The screw longitudinal axis of the fixing screw is perpendicular to the adjusting spindle and to the hinge plate.

Against this background, the invention has for its object to provide a door hinge for aluminum doors, which allows a simple way and a compact design a lateral adjustment. In particular, the design should also be suitable for heavy loads.

Solution to the problem and object of the invention is a door hinge for aluminum doors according to claim 1.

According to the present invention, an accurate stepless adjustment by means of the at least one adjusting spindle is possible. Contrary to known door hinges For aluminum doors with an adjusting spindle, this results in the advantage that the receptacle can be carried out particularly simply and does not itself have to have adjusting means. It should be noted that the inclusion in the gap between the door frame and door leaf is arranged, which can be kept small due to the required installation space. In order to further reduce the assembly height on the associated extruded profile, according to a preferred embodiment of the invention, the fixing screw is designed as a simple threaded pin, which can be completely inserted into the receptacle.

According to the invention, the longitudinal axis of the screw is arranged at an oblique angle with respect to the hinge flap, in which case the receptacle in the region of the fixing screw expediently has a section which extends obliquely with respect to the hinge flap. Basically, the recording can be made with the slot of solid material. In order to facilitate the manufacture and assembly of the door hinge, the receptacle is preferably composed of a base body and an end plate, wherein the slot is formed by a gap between the base body and the end plate. Since the basic body is to be adapted in its shape to the contour of the extruded profile, this is preferably made as a casting. The end plate, which may be in the form of a simple, cut piece of sheet metal, is to be fastened to the base body, for example by riveting, screwing or welding. From a production point of view, in particular riveting offers.

According to an advantageous embodiment of the invention, the body is clamped to the extruded profile, so that on the one hand, a variable arrangement is possible and on the other hand, no holes and no insertion piece must be introduced into the extruded profile.

Thus, the extruded profile may have a C-groove, on which the door hinge is fastened. According to an advantageous development of sliding blocks are then provided which are used in a first orientation in the C-groove of the extruded profile and engage behind in a second orientation front portions of the C-groove. The receptacle can then be fastened with screws to the sliding blocks thus arranged, wherein the sliding blocks and the receptacle are clamped at a tightening these screws to the C-groove.

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 increase and / or slight fixation can be provided between a thread of the sliding blocks and the associated 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 screws then the increased friction or slight fixation is overcome, whereby the recording is locked by clamping.

The configuration of the first hinge part is not limited within the scope of the invention. According to a preferred embodiment, however, this has for mounting an associated extruded profile through holes which are formed as extending in the horizontal direction elongated holes, wherein the first band part receives at least a pair of grub screws which are arranged at a horizontal distance from each other and when tightening cause a fixation of the first hinge part by wedging in the opposite direction.

Due to the formation of extending in the horizontal direction slots alone can not be easily handled pressure position can be realized because when loosening the corresponding, the through holes of the first hinge part cross-bolts the heavy door without further adjustment can not be accurately positioned in a simple manner, the Weight of the door also favors a barely controllable tilting.

According to the advantageous development paired threaded pins are provided as adjusting means for Andruckverstellung, 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, for example, be made such that the threaded pins each have a conical tip to when tightening directly to a respective associated web of the extruded profile Act. The setscrews are then arranged offset from the associated web so 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. Conveniently, the setscrews are each arranged laterally one of the passage holes formed as a slot.

Another aspect 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. According to such an embodiment, the carrier is first attached as a separate part to the extruded profile during assembly of the door hinge. In particular, the carrier can be fixed by a clamping connection, in which case no Holes must be introduced into the extruded profile. 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. If, as described above, a pressure adjustment by at least one pair of grub screws is provided, they can act on associated surfaces of the carrier, whereby an adjustment can be realized. Preferably, however, it is provided that the setscrews act directly via a wedge or the like directly on associated webs of the extruded profile. Thus, openings may be provided on the carrier, through which the threaded pins extend, wherein the threaded pins 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.

If a C-groove is also provided on the extruded profile associated with the first strip part, the carrier can be fastened with sliding blocks, as described above in connection with the receptacle.

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.

According to a preferred embodiment, an adjustment of the door leaf in two mutually perpendicular horizontal directions relative to the door frame is made possible. 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 screws 14, a free positioning of the first band portion 1a in a predetermined adjustment range of, for example 1 mm can be realized.

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. 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 required for the adjustment by means of the adjusting screws 20 game is eliminated.

According to the invention, 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.
