Description

The invention relates to a band assembly for doors, windows or the like with a hinge part, which comprises a hinge part and a fastening part, wherein arranged to provide the adjustment possibility of the wing in the frame, the fastening part relative to the attachment surface facing it on the wing or on the frame is.

Such a band arrangement is for example from the DE 101 52 366 C5 known. It comprises a receiving piece which can be fixed in a hollow profile. In the receiving piece guide bores are provided, which continue in perforations in a mounting side forming the profile wall. On the fastening part of the hinge part support pins are provided, which are designed to be inserted into the guide holes and optionally spreadable, so that the determination of the hinge part can be done in the desired position by jamming the support pins in the guide holes.

The adjustment of the wing in the frame for the purpose of adjustment is a threaded member which is fixed to the fastening part in the adjustment and a Having external thread which is screwed into a complementary, provided in the receiving piece internal thread.

A disadvantage of this band assembly that it is expensive to manufacture because of the large number of different components.

The DE 44 05 360 A1 discloses a band with a cylindrical fastening part with integrated hinge part, such that altogether at least substantially rotationally symmetrical band parts result. The fastening part is provided with diametrical bores, which are penetrated by threaded pins, which may have radially projecting heads. One of the threaded pins may have a recess (circumferential groove), and be fixed by means of a locking pin engaging in this groove in both directions of its axial longitudinal extent on the fastening part.

The WO 02/27128 A1 discloses a hinge part for a door hinge of a window, door or furniture hinge with also at least substantially cylindrical attachment part, which may have a guide track (groove) into which a guide collar (projection) of a fastening pin can be inserted.

The DE 19 607 029 C1 discloses a band with a cylindrical fastening part, which has a threaded pin which can be screwed into a support bush, which passes through a plurality of walls of a frame (hollow profile).

The EP 0 874 123 A1 discloses a hinged band in which a boring pin can be captively secured to the fixing member by forming by dipping at the bottom of the recess two of the head of the boring pin cross material lobes.

The CH 658 098 A5 shows a band with band lobes, from which pins protrude in a coronary manner, which engage in holes in the door. It is a screw provided, which is virtually free of play, but easily rotatable connected to the hinge strap and can be screwed into the door.

The invention is therefore an object of the invention to provide a band assembly, which allows adjustment of the band portion relative to the mounting surface of a frame or a wing for the purpose of adjustment and is inexpensive to produce.

This object is achieved by the reproduced in claim 1 band assembly.

In the band assembly of the present invention, the attachment member is mountable to a mounting surface of the frame or the wing, which may be formed by both the front surface of the frame or the wing or a narrow side of the wing or the frame. In the first case, the adjustment would be perpendicular to the frame or wing plane, in the second case parallel. According to the invention, the band arrangement comprises at least one guide member which can be attached to the fastening surface and guides into a guide recess in the fastening part, which is accomplished by a substantially play-free receptacle in the guide recess, so that the fastening part can be displaced perpendicularly to the fastening surface.

The band assembly further comprises an adjustment member having a threaded shaft and a radial projection, wherein the threaded shaft with a complementary thread on the frame or wing and the radial projection with a receptacle on the fastening part, or the threaded shaft with a complementary thread on the fastening part and the Radial projection with a receptacle on the frame or wing is engageable.

Therefore, the band assembly according to the invention requires only the at least one guide and the at least one adjusting member for the adjustment.

The guide member is rotationally symmetrical about its longitudinal axis, as this simplifies the manufacture of the band assembly. It also has a threaded extension, with which the guide member is screwed into the frame or the wing, and the guide portion which cooperates with the guide recess of the fastening part of the hinge part on.

The threaded extension has a smaller diameter than the guide region. By this measure, the attachment of the guide member is facilitated in the correct position, since it only needs to be screwed as far into the frame or the wing until the end face of the guide portion comes into contact with the mounting surface.

According to the invention, a radial projection is provided at the end of the guide region opposite the threaded extension. This then serves as a stop for the fastening part of the band part and thus limits the adjustment.

In a particularly preferred embodiment of the band assembly according to the invention, an undercut is provided on the fastening part of the band part, in which engages the radial projection of the adjusting member. As a result of the positive engagement thus effected, adjusting forces are reliably introduced into the fastening part by the adjusting element in both adjustment directions.

In a particularly preferred constructional variant, the undercut is formed by edge lips of a cross-sectionally C-shaped groove which runs perpendicular to the adjustment direction. The adjusting member can then be mounted with the undercut in a simple manner by lateral insertion.

In a first embodiment, the thread of the threaded extension of the guide member may be self-tapping. This embodiment is then particularly suitable for mounting on wings or frame with solid or thick-walled frame profiles or wing edges.

However, it is also possible to form the thread of the threaded extension of the guide member as a machine thread.

The band arrangement according to the invention is particularly suitable for mounting on a hollow profile when it comprises a first threaded element with an external thread which can be screwed into at least two parallel walls of the profile and which has an internal thread complementary to the thread extension of the guide element. The assembly is then characterized in that first the threaded element is screwed into the profile and that usually so far that it does not or only slightly beyond the mounting surface. Subsequently, the guide member is screwed into the internal thread. The holding forces introduced via the guide member are then introduced via the threaded element into the at least two walls of the profile, whereby the holding forces which can be absorbed by the profile are considerably increased.

Accordingly, in a further preferred embodiment of the band assembly according to the invention a second threaded member is provided with an external thread, which is screwed into at least two parallel walls of the profile and which has a thread extension of the adjusting complementary internal thread. This second threaded element then serves in a corresponding manner for receiving the adjusting element, wherein the adjusting forces are then introduced into the profile walls penetrated by it via the threaded element.

The first and second threaded elements are - to reduce the number of different components and thus the manufacturing cost of the band assembly according to the invention - identical.

The fastening part 2 has a substantially flat underside 7, which faces a fastening surface 8 of the wing profile 6. In the fastening part 2 further two guide recesses 9 are incorporated, which are formed as through holes. The diameter of each guide recess 9 is adapted to the outer diameter of a guide portion 10 of a guide member 11 such that the guide portion 10 forms a substantially backlash-free sliding fit with the associated guide recess 9.

From a front end 12 of the guide portion 10 extends a threaded extension 13, which has a thread formed as a machine thread external thread. At the opposite end face, a radial projection 14 is provided on the guide member 11. It forms a stop for the fastening part 2.

Furthermore, the band assembly comprises an adjusting member 15, which in turn comprises a threaded extension 16 with a machine external thread and a radial projection 17. The adjusting member 15 is mounted in the adjustment direction P form-fitting manner on the fastening part 2, since the latter has a cross-sectionally C-shaped groove 18, the edge lips 19 form undercuts for the radial projection 17.

How out Fig. 1 is apparent, an assembly of the band assembly to a frame or a wing already done by the band member 1 is fixed by means of the guide and adjustment members 11 and 15 without further aids by the guide and adjustment members 11, 15 with their threaded extensions 13th , 16 are screwed directly into corresponding threaded holes in the wing or in the frame.

However, if - as in the embodiment shown in the drawing - the band assembly is particularly suitable for mounting on hollow profiles, so further, first threaded elements 20 are provided having external threads 21, by means of which the threaded elements 20 in at least two parallel walls 22 of the wing profile. 6 are rotatable.

The threaded elements comprise a threaded bore 23, which is complementary to the thread of the threaded extension 13 of the guide member 11 is formed. The guide member can then - as in particular Fig. 4 can be removed - are screwed into the threaded hole 23. The holding forces transmitted by it are then introduced into the walls 22.

In a corresponding manner, a second threaded element 24 is further provided, which comprises a male thread 21 corresponding to the external thread 25 and is screwed in a corresponding manner as the first threaded member in the wing profile 6. In the likewise existing threaded bore 26, the adjusting member 15 is screwed. How out Fig. 3 is apparent, a rotation of the adjusting leads to a displacement of the wing in the adjustment direction P, since the radial projection 17 engages in the groove 18.
