Description

The invention relates to a band for doors, windows or the like, with at least one fastened to a frame frame hinge part, with at least one attachable to a wing leaf hinge part, with an engaging in the band parts and these pivotable about a hinge axis interconnecting hinge pin in the leaf hinge part against rotation about the hinge axis relative to the wing hinge part and in the direction of the hinge axis can be fixed, and with a surrounding the hinge pin, having an external thread threaded bushing which engages in a provided in the wing hinge part, complementary internal thread and with its lower end side directly or indirectly on the frame hinge part is supported.

Such a band is from the DE 297 13 254 U1 known. In this band, the threaded bushing comprises at its lower, projecting from the wing hinge part area a Verdrehbetätigungsflansch having Betätigungsausnehmungen to which a hook wrench for rotary operation for the purpose of adjusting the wing hinge part can be attached in the direction of the hinge axis.

A disadvantage of this tape that the length of the protruding from the wing hinge portion of the threaded bushing for attaching the hook wrench must have a certain minimum, so that the distance between the wing hinge part and the frame hinge part or between the hinge parts in the direction of the hinge axis is just this minimum. This band therefore gives a ragged, visual impression. Furthermore, the visual impression is additional disturbed by the Betätigungsausnehmungen. Finally, the area between the two hinge parts is difficult to clean, so that easily accumulates dirt here, which can lead to an increase in wear and noise on actuation of the tape.

From the DE 200 07 759 U1 a door or window hinge is known, which has a frame hinge part and a wing hinge part, which are connected by means of a hinge pin hinged together. This band further comprises a threaded bushing which is rotationally coupled to the hinge pin, but is arranged to be displaceable in the direction of the hinge axis. This threaded bushing comprises a lower, externally threaded and an upper, non-threaded portion, wherein the outer diameter of the unthreaded portion corresponds approximately to the core diameter of the external thread. The areas are each provided on their facing sides with an axially projecting telescopic collar over which the two areas engage with each other.

The lower, the outer thread comprehensive range of threaded bushing is rotatably connected to the hinge pin. A height adjustment can thus be done by rotary actuation of the hinge pin.

In order to prevent a pivoting of the door or window sash leads to an adjustment of the wing hinge part relative to the frame hinge part, a grub screw is provided, which is mounted in a threaded bore in the wing hinge part and rotatable by a hole in the lower part of the threaded bushing against the hinge pin is. In order to take into account a relative height adjustment, which is required for adjustment, between the hinge pin and the lower part of the threaded bushing, four holes, each offset by 90 °, are provided on the lower part, which are formed as elongated holes. These four slots should be sufficient to obtain a sufficiently fine height gradation at usual pitches of the thread.

The disadvantage of this tape that the height adjustment can not be made infinitely. In addition, there is a risk that after adjustment at a Turning the grub screw for fixing one of the holes is not taken, whereby the threaded bushing can be damaged or even destroyed.

The invention is therefore based on the object to develop a tape which is improved in terms of the aforementioned disadvantages.

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

According to the threaded bushing with the hinge pin is rotationally coupled, but arranged displaceable in the direction of the hinge axis. By this measure, it is no longer necessary to provide a Verdrehbetätigungsflanschse on the threaded bushing, but the rotational movement can be initiated via the hinge pin. For this purpose, this may have at one end face means for applying a rotary tool, such as a screwdriver or a hexagonal wrench. Since the hinge pin is arranged to be displaceable in the direction of the hinge axis, the wing hinge part can be moved in the direction of the hinge axis, i. be adjusted vertically, without the hinge pin displaced relative to the receiving frame hinge part. After the adjustment process, the wing hinge part can be fixed in the desired position by the hinge pin is set against further rotations relative to the wing hinge part.

The rotational coupling between the threaded bushing and the hinge pin can be effected in that the hinge pin has a longitudinal groove, in which engages a radially inwardly projecting projection of the threaded bushing.

In the band according to the invention, the threaded bushing comprises a lower, the outer thread having and an upper, unthreaded portion, wherein the outer diameter of the threadless portion corresponds approximately to the core diameter of the external thread. The guide function for the hinge pin generated by the threaded bushing is ensured due to this measure, without it being necessary for mounting the threaded bushing to screw it over its entire length in the provided in a recess of the leaf hinge part internal thread. The time required for a basic assembly of the threaded sleeve to a middle position is thereby reduced.

The thread having the external thread and the unthreaded region is formed in each case by separate sleeve parts. Between the sleeve parts a coupling element for fixing the two sleeve parts in the direction of the hinge axis is provided, which is arranged rotationally fixed in the wing hinge part. The determination of the hinge pin in the leaf hinge part can then be carried out in the region of the coupling element in the realization of a stepless adjustability, since the lower sleeve part is rotatable relative to the coupling part about the hinge axis. It is also avoided by this measure that the unthreaded area in the basic assembly of the threaded bushing or in the adjustment rotates with rubbing on the threads of the internal thread of the wing hinge part, which could lead to an increase in the wear of the internal thread.

The coupling element preferably comprises at each front end coupling means, which are engageable with counter coupling means on each one of the sleeve parts. The basic assembly of the threaded bushing is then, for example, characterized in that the part provided with the external thread is screwed into the middle position in the receptacle, the locking element inserted from above into the recess and finally the unthreaded sleeve member is pressed with such a pressure from above into the recess in that the coupling means engage the counter-coupling means.

The coupling means preferably comprise a locking projection extending in a plane perpendicular to the hinge axis.

The counter-coupling means then preferably have a circumferential latching groove formed complementary to the latching projection. Locking projection and locking groove are dimensioned so that they can be brought under overcoming elastic deformation forces in engagement.

Particularly preferred is a development of the coupling element which comprises a part which can be brought into engagement with the one bushing part and another part which can be brought into engagement with the other bushing part. In other words, the coupling element itself is formed in two parts. Due to this measure, it is possible first to bring the respectively associated part of the coupling element with the corresponding bushing part into engagement and then to introduce the respective bushing part together with the coupling part into the receptacle. It then only needs the connection of the two part of the coupling element are produced, for which purpose these parts in turn comprise mutually complementary, engageable latching means.

Particularly preferred is an embodiment of the band according to the invention, in which the parts of the coupling element parallel to the hinge axis extending extensions comprise, which can be coupled via a latching connection in the direction of the hinge axis.

Particularly preferred is a development of the tape according to the invention, in which the projections in guide grooves in the penetrated by the hinge pin, the internal thread for the threaded bush having recording run in the leaf hinge part. In this way, it is first ensured that the coupling element in the basic assembly and the adjustment can not rotate, thereby preventing that a torque is transmitted to the unthreaded sleeve part.

Furthermore, this configuration allows the diameter of the receptacle between the guide grooves can be selected so that it is only slightly larger than the outer diameter of the hinge pin. The inner circumferential surface of the receptacle thus protrudes up to the outer surface of the hinge pin, so that in this area for fixing the hinge pin after adjustment in a transverse to the hinge axis threaded bore can serve stationary grub screw.

The designated 100 in the drawing as a whole band comprises a wing hinge part 1, which can be arranged in a three-piece band between two frame hinge parts, not shown in the drawing.

The wing hinge part 1 comprises a fastening part 2 and a hinge part 3.

The fastening part 2 is provided with slot-shaped openings 4 and 5 approaches, so that a known arrangement for adjusting the wing perpendicular to the hinge axis S, ie for horizontal adjustment of the door can be used.

In the hinge part 3, a receptacle 6 is provided, which has an internal thread 9 both at its lower according to the drawing, as well as in the drawing upper end portion 7, 8 (see. Fig. 3 ).

The end regions 7 and 8 are connected to one another via a central region 10, the inner diameter of which is only slightly larger than the outer diameter of a hinge pin 11 passing through the receptacle 6. The central region 10 comprises two guide grooves 12, which lie opposite one another with respect to the hinge axis S, in particular in FIG Fig. 4 is recognizable.

In the receptacle 6 a designated as a whole with 13 threaded bushing is provided. It comprises a lower part 14 with an external thread 15 and a unthreaded, upper part 16 whose outer diameter corresponds approximately to the core diameter of the lower part 14. Between the lower and the upper part 14, 16 a coupling element 17 is provided, which comprises a lower part 18 which can be brought into engagement with the lower part 14 and a part 19 which can be brought into engagement with the upper part 16. The two parts 18, 19 each have a connecting flange 20, 21 which lies in a plane perpendicular to the hinge axis S level. Both connecting flanges 20, 21 each comprise a circumferential latching projection 22, 23, which is in each case with a not visible in the drawing, complementary to the latching projection formed, circumferential locking groove in the lower or upper part 14, 16 is engaged. The latching projections 22, 23 and the complementary latching grooves are dimensioned such that in the direction of the hinge axis S a clamping fit between the coupling element 17 and the parts 14, 16 is effected, but the parts 14, 16 are rotatable about the hinge axis S relative to the coupling element 17 ,

Of the connecting flanges 20, 21 extend on the latching projection 22, 23 respectively opposite side two extensions 24, 25; 26, 27. The extension 24 has a latching receptacle, which can be brought into engagement with a latching projection provided on the extension 26. Accordingly, a latching projection is provided on the extension 25, which can be brought into engagement with a latching receptacle on the extension 27. The parts 18, 19 of the coupling element 17 are accordingly the same components, which are, however, rotated by an angle about the hinge axis S of 180 ° to each other. The facing each other Inner surfaces of the extensions 24, 25; 26, 27 have an adapted to the diameter of the hinge pin 11 radius of curvature. Their outer contour is adapted to the contour of the guide grooves 12 such that the two parts 18, 19 are insertable by inserting the projections in the guide grooves in the receptacle 6 and by means of existing at the ends of the extensions locking devices to each other. The central region 10 of the receptacle 6 has a length which is smaller than the distance between the connecting flanges 20, 21 relative to one another by the maximum adjustment path, so that the coupling element 17 can be displaced in the direction of the hinge axis S by the adjustment path.

How out Fig. 3 is apparent, learns the threaded bushing 13 by the coupling of their components via the locking connections together in their entirety a displacement relative to the wing hinge part in the direction of the hinge axis S, when the lower part 14 is rotated. In order to initiate the rotational movement, the lower part 14 has an inwardly directed, radial projection 28, which in particular in Fig. 5 is recognizable. The projection is adapted to a longitudinal groove of the hinge pin 11, so that it is slidable through the lower part 14, but rotatably connected. For the purpose of rotational actuation of the lower part 14 of the threaded bushing 13, it is therefore only necessary to rotate the hinge pin accordingly. As in Fig. 4 can be seen, the wing hinge part 1 has a transverse to the hinge axis S extending threaded bore 29, which is arranged approximately in the middle of the longitudinal extent of the hinge part 3 of the wing hinge part 1 and extends outside the guide grooves 12 into the central region 10. The threaded bore 29 serves to receive a grub screw 30, with which a clamping fit between the wing hinge part 1 and the hinge pin 11 can be effected. This clamping fit is necessary to prevent that after the vertical adjustment of the wing, the threaded bushing 13 can rotate relative to the wing hinge part, since this would be associated with a misalignment. Thus, the grub screw 30 is also an effective stop against a violent expelling of the hinge pin in the direction of the hinge axis S and thus an effective burglar alarm, a recess 31 is provided on the hinge pin 11, whose length is chosen so that a displacement of the hinge pin in the wing hinge part to the maximum adjustment is possible. The radially projecting boundary surfaces of the hinge pin 32, 33 form stops for the hinge pin on the grub screw 30th
