Hinge part of a hinged band

The invention relates to a hinge part of a hinge for attachment to a mounting wall of a multi-chamber hollow profile, in particular a wing hinge part, wherein the hinge part comprises a fixed attachable to the multi-chamber hollow profile mounting member and a displaceable relative to the mounting member and fixable in a desired displacement position adjustment part.

Such a band part is known for example from EP 1 106 763 B1. The attachment of the mounting part to the mounting wall is carried out by means of six screws that pass through the mounting part in designated holes.

Due to the ever-increasing demands on the thermal insulation of buildings today, the hollow chamber profiles regularly consist of multi-chamber profiles, in which usually several insulating chambers are integrated. To ensure that the glazing also meets the high requirements for thermal insulation, at least triple glazing is regularly provided. Due to the weight gain caused thereby, in particular plastic profiles on metal reinforcements, so that these profiles can also accommodate the high weights without considerable deformation of the profile. In order to minimize the weight of the plastic profiles which are heavy due to the metal reinforcement, the wall strengthen the partitions between the individual profile chambers dimensioned small.

In order to be able to produce sufficiently high holding forces in such multi-chamber hollow profiles, at least part of the fastening screws must be screwed into the metal reinforcement in order to fasten the band part known from EP 1 106 763 B1. As a result, a force is exerted on the mounting part, which tries to pull it against the metal reinforcement. This regularly leads to undesirable deformations of the mounting wall. These deformations lead to a considerable deterioration of the statics, because the required tightening torque is not achieved, the visual appearance and the adjustment, since the displacement part against the mounting part can be regularly moved only with no or only slightly deformed mounting wall.

The invention is therefore based on the object to provide a band part of the type mentioned, which is better suited for attachment to multi-chamber hollow sections. This object is achieved by the reproduced in claim 1 band.

In this band part, the mounting part according to the invention comprises at least a first pass extension, which is provided for at least almost play-free engagement in holes in the mounting wall and in the inner wall, and at least a second pass extension, which is provided for at least almost play-free engagement in holes only the mounting wall.

It has been found that surprisingly high holding forces can be transmitted from the band part to the multi-chamber hollow profile by this engagement of the pass extensions, without resulting in any noteworthy profile deformations. Because clamping forces acting between the mounting part and the inner wall, are no longer needed for the introduction of force. Therefore, a fixing of the mounting part on the mounting wall, for example, by at least one preferably self-drilling fastening screw is provided, however only has to engage in the mounting wall, whereby a deformation of the multi-chamber hollow profile is avoided when tightening the mounting screw. It is particularly preferred to form the at least one first and / or at least one second pass extension expansion-dowel-like. By "expansion dowel-like" it is meant that measures are provided with which the outer diameter of the fitting extension can be enlarged over at least part of its length so as to be able to press its outer periphery against the edges of the perforations in the fastening wall and the inner wall For many applications, in particular in the case of multi-chamber hollow profiles in which the inner wall is part of a reinforcement, in particular of metal, sufficiently high holding forces are achieved solely by the spreading This configuration is particularly suitable for a one-time, permanent attachment of the mounting part to the multi-chamber hollow profile, since it is simple and inexpensive to manufacture, but the expansion pin is reg elmäßig only with difficulty can be removed again.

In particular, for a releasable fastening a second embodiment of the expansion dowel-like fitting extension is suitable in which this includes a non-circular inner contour, and an expansion pin is provided which has an approximately complementary outer contour, so that he at least in a certain angular position without spreading of the fitting extension can be introduced into this and by a rotation about its longitudinal axis, for example, by an angle of 90 °, spreading of the fitting extension is effected. For example, the cross section of the inner volume of the fitting extension and the outer cross section of the expansion pin can be designed approximately elliptical.

The achievable with the passport processes holding forces can be further increased if they have contoured surfaces. With "contoured" is every shape meant, which leads to a positive interaction between the keyway and Lochungsrand the respective wall. By way of example, a corrugation transverse to the longitudinal extent of the pass-extension may be mentioned here. The pass extensions can be arranged on the mounting part such that they pass through the adjustment in a straight guide. The pass extensions then serve immediately the leadership of the adjustment during the adjustment and the desired adjustment, so that it can be dispensed with further measures to guide the guide member.

If the band member is intended for attachment to a multi-chambered deckle hollow profile, i. Such a, where a part of the multi-chamber hollow profile in a closed wing partially overlaps the adjacent profile, be suitable, the second fitting extension is preferably provided for engagement in a perforation in the mounting wall in the Aufdeckbereich. Due to this measure, the distance between the hinge axis and the perpendicular to the hinge axis seen closest fitting extension and thus the lever, are introduced via the holding forces in the multi-chamber hollow section, kept as small as possible. In the case of the Aufdeck multi-chamber hollow profile, the second fitting extension may additionally comprise a fastening means, preferably a screw, with which it can be fastened with the cover wall of the Aufdeckbereichs opposite the mounting wall. In this case, forces are introduced not only in the mounting wall, but also in the Aufdeckwand in the Aufdeckbereich on the second fitting extension, so that this variant is suitable for the transmission of particularly high holding forces and thus particularly heavy wings.

In the band part according to the invention, a plurality of first pass extensions and a plurality of second pass extensions may be provided. Both the first and the second pass extensions can be arranged one above the other, viewed in parallel to the hinge axis. For a variety of applications, it is sufficient for the transmission of the expected holding forces to provide two parallel to the hinge axis arranged one above the other arranged first and second pass extensions, which are perpendicular to the hinge axis spaced from each other. In the drawings, embodiments of the hinge part according to the invention are shown schematically. 1 a) to d) show a first embodiment in an exploded perspective view, in an exploded view according to view a) from above, in a top view in the assembled state, and a view of the assembled hinge part from above; Fig. 2a) and b) is a view of a further embodiment in a Fig.

The illustrated in Fig. 1 first embodiment of a hinge part 100 according to the invention comprises an adjustment part 1, to which a hinge part 2 is integrally formed, which comprises a receptacle 3 for a not shown in the drawing, known per se adjustment of a hinge pin. In the adjustment part 1 are two parallel to each other and perpendicular to the longitudinal axis of the receptacle 3 extending straight guides 4 in the form of slot-shaped apertures. 5 intended. In the middle between the slot-shaped openings is an outwardly open, fork-shaped carrier. 6

Furthermore, the band part 100 comprises a mounting part 7 on which right pass extensions 8 and on the left in FIG. 1 shown on the left second pass extensions 9 are arranged in pairs in the direction of the longitudinal extent of the receptacle 3 one above the other. The first pass extensions 8 have a significantly greater length than the second pass extensions 9. In the embodiment shown in Fig. 1, the passport extensions 8, 9 are formed dome-like. They comprise expansion screws 10, 11, which can be screwed into inner volumes, tapering towards the end, of the first and second passport extensions 8, 9, so that they spread apart in their slotted regions. Instead of the expansion screws can be used also in the inner volumes of pressable Spreizstifte.

In the mounting part, an internal thread 12 is provided, in which a complementary external thread 13 having adjusting screw is screwed. The latter comprises an annular groove 14, which is in engagement with the driver 6. As is apparent in particular from FIG. 1 c), the adjusting part 1 and the mounting part 7 shift relative to one another when the adjusting spindle 13 is rotationally actuated, for example, by the frontal projection of a suitable turning tool not shown in the drawing. Since the first and second pass extensions enforce the slot-shaped apertures substantially free of play, the adjustment part 1 is guided relative to the mounting part 7.

The illustrated in Fig. 1 embodiment of the band member 100 according to the invention is intended for exclusive attachment of a visible side, and front of the multi-chamber hollow section. 2. The second exemplary embodiment of a strip part 200 according to the invention shown in FIG. 2 differs therefrom in that it additionally comprises a fastening angle 15 which is provided for encompassing a side of the multi-chamber hollow profile perpendicular to the front side and, for example, with the aid of FIG not shown, passing through it in holes fastening screws with this page is screwed. In order to adjust the band portion 200 to different profiles, the mounting bracket 1 15 in the direction of arrow P verlager- and fixed in a desired displacement position on the mounting part 1 07 is arranged. Otherwise, the band part 200 corresponds in its construction and its function to the band part 100 described above.

Fig. 3 shows - schematically - an embodiment of the hinge part 300 according to the invention mounted on a multi-chamber hollow section H. The first pass extensions 8 protrude through holes in a mounting wall 16, which forms the front side of the multi-chamber hollow section H, and through perforations in an inner wall 17, which is part of a metal reinforcement 18. The second pass extensions 9, however, enforce only holes in the mounting wall 16th

The first and second pass extensions can, for example, be designed in the manner of an expansion dowel as shown in FIGS. 1 and 2. However, it is also possible any further design that ensures an at least almost play-free seat or a clamping fit in the walls 16, 17. In addition, in Fig. 3 denoted by 207 mounting member by means of one or more not shown in the drawing mounting screws to be secured, but then only need to engage in the mounting wall 16.

In the further variant of a belt part 400 according to the invention shown schematically in FIG. 4, the mounting part designated here by 307 is secured by an additional fastening screw 31 9. It is screwed from the inside into a mounting area A of the multi-chamber hollow section H, so that it is not visible from the outside when the sash is closed and can not be unscrewed. By this arrangement, the fixing screw 319 therefore does not deteriorate the visual appearance of the tape and at the same time increases burglar resistance, since it can not be unscrewed with the wing closed.

The fastening screw 31 9 is screwed in a hereby designated 309 second pass extension of the front side thereof. The attachment extension 309 is designed expansion dowel-like, so that the fixing screw 319 as it were causes a press fit of the second fitting extension 309 in the mounting wall 16. Also, the first pass extension designated here by 308 is expansion-dowel-like, for example like the one with reference to FIG. 1 described trained. Again, however, any other embodiment that ensures at least one essentially play-free seat or a clamping fit in the walls 16, 17, conceivable.

Various embodiments of mounting parts are shown in FIGS. 5 to 9.

In the mounting part 407 of FIG. 5, the first and second pass extensions 408, 409 are designed expansible dowel. Its outer circumferential surface is contoured, so as to improve the clamping action between the first and second passport extensions and the profile walls.

In the embodiment shown in Fig. 6, the mounting part 507 additional holes 520 through which mounting screws, not shown in the drawing can be screwed into the mounting wall of the profile. In Fig. 7, the first and second fitting extensions 608, 609 are formed as rigid, cylindrical pins with contoured surfaces. The fixing of the mounting part 607 in the longitudinal direction of the extensions is then carried out exclusively with fastening screws, not shown in the drawing, which are screwed through holes 620 in the mounting wall of the profile.

In contrast to the mounting part 607, in the mounting part 707 in FIG. 8, the first pass extensions 708 are designed in the manner of an expansion dowel, so that these holding forces also act on the profile in the longitudinal direction of the extensions. The expansion dowel-like extensions can be configured in the manner shown with reference to FIG. 9 to 1 1.

The first pass extensions 808 have a non-circular, approximately elliptical in cross-section inner contour 821. In the embodiment shown in Fig. 9 to 1 1 This inner contour 821 has two longitudinal regions which differ in that their approximately elliptical cross sections are rotated by 90 °. This embodiment becomes clear in particular by viewing the expanding pin 822 shown in FIG. 10. It has a first, front elliptical area 823 and a second, rear elliptical area 824, which is rotated 90 ° relative to the first elliptical area 823. Furthermore, the spreader pin 822 comprises a rear cylindrical portion 825, which rests at least substantially free of play on a substantially cylindrical bore 826 of the mounting member 807. For fixing the mounting part 807 to a multi-chamber hollow profile, the spreader pins 822 are inserted in a rotational position in the respective passport extension in which the elliptical areas 823, 824 are aligned with the respectively associated inner contour 821 after inserting the pass extensions in the profile holes. Subsequently, the expansion pin is rotated with the aid of a rotary tool at an angle of about 45 °, wherein the respective attachment extension 807 is spread. For additional attachment to the multi-chamber hollow profile holes 820 are again provided on the mounting part 807, through which fastening screws are screwed into the mounting wall of the profile.
