Description

[0001] System with hollow profile and band part of a hinge band

[0002] The invention relates to a system comprising a hollow profile with a fastening wall and with at least one inner wall, and with a band part of a hinge band fastened to the fastening wall, wherein the band part comprises a mounting part which can be fixedly attached to the hollow profile and which has a plurality of positioning extensions, of which at least one is designed in the manner of an expansion dowel, and an adjustment part which can be displaced relative to the mounting part in a displacement direction and can be fixed in a desired displacement position.

[0003] Such a system is known from EP 2 504 511 Bl.

[0004] In this system, the mounting part comprises at least one positioning extension, which is provided for at least almost play-free engagement in perforations in the fastening wall and in the inner wall, and at least one second positioning extension, which is provided for at least almost play-free engagement in perforations only in the fastening wall.

[0005] While it has been demonstrated that this system can transfer high holding forces from the hinge part to the hollow profile, particularly when the positioning extensions are designed like expansion dowels, i.e., measures are provided by which the outer diameters of the positioning extensions can be enlarged over at least part of their length, in order to press the outer circumferences against the edges of the holes in the fastening wall and the inner wall. However, it has also been demonstrated that undesirable, permanent deformations can occur in the area of ​​the fastening wall simply by mounting the mounting part on the hollow profile.

[0006] The invention is therefore based on the object of creating an improved system in this regard.

[0007] This object is achieved by the system recited in claim 1. The invention also relates to a hinge part of this system and a hinge band with such a hinge part.

[0008] In the system according to the invention, the positioning extensions are adapted to the hollow profile in such a way that they only engage in holes provided in the fastening wall.

[0009] Surprisingly, it has been shown that engagement of the positioning projections exclusively in the mounting wall is usually sufficient to transmit forces of the required magnitude between a sash and a frame. This is particularly true when the positioning projections are all designed like expansion dowels, so that their outer peripheries press against the edges of the hole in the mounting wall after the mounting part is installed. Since no positioning projection interacts with an inner wall of the hollow profile, contrary to the teaching of EP 2 504 511 B1, permanent deformation of the mounting wall due to mounting forces alone is reliably avoided.

[0010] If, as is often the case, the hollow profile is a plastic profile with a metal-reinforced inner wall, the system according to the invention is further advantageous in that holes for the positioning extensions only need to be created in the plastic mounting wall and no longer additionally in the possibly metal-reinforced inner wall. This reduces the assembly effort with the system according to the invention. On the other hand, the undesirable generation of metal shavings during the assembly process is avoided. To maximize the forces that can be transmitted from a sash in a frame using the system according to the invention, it is advantageous to design all positioning extensions in the manner of expansion dowels.

[0011] Preferred embodiments of the positioning extensions each comprise an expansion pin or an expansion screw. The use of an expansion screw has the advantage that the expansion effect can be released by unscrewing the expansion screw, allowing the assembly part to be removed from the hollow profile after assembly. When using expansion pins, the assembly of the assembly part is generally faster, since an expansion pin can be driven into the expansion anchor with just a single hammer blow, for example, thus achieving the positioning function.

[0012] In a particularly preferred embodiment of the system according to the invention, the positioning extensions are arranged on the mounting part in such a way that they extend through the adjustment part in one or more straight guides extending in a direction of displacement. The positioning extensions then serve to guide the adjustment part during adjustment and in the desired adjustment position, eliminating the need for additional measures for guiding the guide part.

[0013] To improve the guiding effect and thus the adjustability of the adjustment part, it is advantageous if at least two positioning extensions are part of a guide element which passes through a straight guide of the adjustment part.

[0014] The guide element is preferably trough-shaped with opposing longitudinal walls such that its open side is provided facing the fastening wall.

[0015] If walls that run obliquely, curvedly, or transversely to the longitudinal walls, which may be part of the positioning extensions, are slotted in such a way that spreading the positioning extensions also leads to an at least partial increase in the distance between the two longitudinal walls of the guide element, a play-free engagement of a straight guide through an adjustment part can be achieved, at least in some areas. This further improves the adjustment accuracy achievable with the system according to the invention.

[0016] Regardless of whether the positioning extensions are parts of guide elements that pass through the straight guides of the adjustment part or not, in order to improve the adjustment accuracy achievable with the system according to the invention, it is preferred to design the positioning extensions in such a way that they are designed to be spreadable at least in a direction oblique or perpendicular to the direction of displacement in the areas in which the positioning extensions pass through the adjustment part in the straight guide.

[0017] The invention also relates to a hinge part of the system described above and to a hinge part equipped with such a hinge band.

[0018] The drawing schematically illustrates exemplary embodiments of the system according to the invention. They show:

[0019] Fig. 1 shows the embodiment of the system according to the invention in a view in the longitudinal direction of a hollow profile with a partially cut band part;

[0020] Fig. 2 shows a band part of this embodiment in a first perspective view;

[0021] Fig. 3 the same band part as in Fig. 2 in a view according to Fig. 2 from behind;

[0022] Fig. 4 the same band part in a perspective exploded view;

[0023] Fig. 5 the same band part in a perspective exploded view according to Fig. 4 from above;

[0024] Fig. 6 shows the same band part in a plan view in the assembled state and Fig. 7 shows the same assembled band part in a view according to Fig. 6 from above.

[0025] The exemplary embodiment of a system 100 according to the invention shown in Fig. 1 comprises a hinge part 1 with an adjustment part 2, onto which a hinge part 3 is formed in one piece, said hinge part comprising a receptacle 4 for a known adjustment bushing of a hinge bolt (not shown in the drawing). Two straight guides 5 in the form of elongated hole-shaped openings 6 are provided in the adjustment part 2, running parallel to one another and perpendicular to the longitudinal axis of the receptacle 4. In the center between the elongated hole-shaped openings 6 is a driver element 7. It is bolt-shaped and sits in a bore 8 of the adjustment part 2. It has a threaded bore 9 running transversely to its longitudinal extent, into which an adjustment spindle 10 adapted to it engages.

[0026] The adjusting spindle 10 is mounted in a mounting part 11 of the band part 1, rotatable about its longitudinal axis, and fixed in the direction of its longitudinal axis such that its longitudinal axis is aligned parallel to the longitudinal extensions of the straight guides 5. For this purpose, the adjusting spindle 10 is arranged in a spindle holder 12 and has a cylindrical spindle head 13, which is supported in the longitudinal direction of the spindle on opposing support surfaces 14, 15 of the spindle holder 12.

[0027] The mounting part 11 further comprises guide elements 16 that extend through the openings 6 over part of the length of the straight guides 5. This allows the assembly comprising the adjustment part 2 and the hinge part 3 to be displaced in a displacement direction V that runs parallel to the longitudinal extensions of the straight guides 5.

[0028] The guide elements 16 are trough-shaped such that, in the assembled state, their open side faces a fastening wall 17 of a hollow profile 18.

[0029] The guide elements 16 are formed on a rear side 19 of the mounting part 11, which faces a front side 20 of the adjustment part 2 and rests against the fastening wall 17 of the hollow profile 18 when mounted thereon.

[0030] Furthermore, positioning extensions 21 are provided on the mounting part 11. A positioning extension 21 is formed on each longitudinal end of a guide element 16 in such a way that it is part of the guide element 16.

[0031] Each positioning extension 21 has a length L which is adapted to the hollow profile 18 in such a way that the respective positioning extension only passes through the fastening wall 17 in a perforation 22, but not an inner wall 17a of the hollow profile 18.

[0032] The positioning extensions 21 are tubular and have longitudinal slots 23, two of which are arranged such that they are penetrated by a plane E running parallel to the longitudinal sides 24 of the guide elements 16. Thus, their outer circumference can be expanded over the length of the slots 23, for example, by screwing an expansion screw 25 into the corresponding positioning extension. The positioning extensions 21 thus have expansion-dowel-like properties.

[0033] At least the slots 23 through which plane E passes extend at least as far as the rear side 19 of the mounting part 11. This causes the guide element 16 to expand, at least in the region of the positioning extensions 21, in a direction perpendicular to plane E under the action of the expansion screws 25, so that its longitudinal sides 24 are pressed, at least in some areas, against longitudinal surfaces 26 of the openings 6. Screwing in the expansion screws 25 therefore not only positions the mounting part 11 on the fastening wall 17 of the hollow profile 18, but also compensates for any play that may be present between the longitudinal sides 24 of the mounting part 11 and the longitudinal surfaces 26 of the openings 6, ensuring a play-free fit of the hinge part 1 on the hollow profile 18.Due to this measure, the hinge part 1, and thus a system 100 comprising this hinge part 1, is characterized by particularly precise and reproducible adjustability in the adjustment direction V. In the exemplary embodiment of the hinge part according to the invention shown in the drawing, additional bores 27 are provided in the mounting part 11. They extend through each of the guide elements 16 in tubular extensions 28 within the respective guide element 16. The extensions 28 also have slots 23 through which one of the planes E passes.

[0034] This ensures that the longitudinal surfaces 26 of a guide element 16 can also spread in the direction of the longitudinal sides 24 in the area of ​​the extensions 28, so that the longitudinal sides 24 can also be pressed against the longitudinal surfaces 26 of the openings 6 in the area of ​​the extensions 28 under the action of the expansion screws 25. The additional bores provide the option of screwing additional fastening screws (not shown in the drawing) into the fastening wall 17 of the hollow profile 18, if necessary to achieve the required holding forces on the profile in an individual case.
