Description

Band part of a hinge band

The invention relates to a band part of a hinge band which can be fastened to a fastening wall of a frame or a wing, wherein the band part comprises a mounting part which can be fixedly attached to the fastening band 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, wherein the mounting part comprises a device with which it engages in a straight guide of the adjustment part which comprises opposing, parallel guide surfaces.

Such a band part is known from EP 2 504 511 B1. In this band part, the device comprises two parallel extensions, each engaging in a straight guide, which are shorter than the respective straight guide in order to allow a displacement of the adjustment part relative to the mounting part.

The disadvantage of this hinge part is that, due to possible manufacturing tolerances, a certain amount of play between the straight guides and the extensions must always be taken into account, which has a negative effect on the adjustment accuracy of the hinge part. In particular, the play can lead to a tilting of the adjustment part with regard to the direction of displacement, which leads to a misalignment of a hinge axis defined by the hinge part. The invention is therefore based on the object of creating a band part which is improved in this respect.

In the band part according to the invention, the device comprises a guide element which comprises two counter-guide surfaces which are parallel to the parallel guide surfaces of the straight guide and are therefore parallel to one another and whose distance from one another can be expanded at least in certain areas. Due to this measure, a play that is usually present due to possible manufacturing tolerances for the assembly of the mounting part and the adjustment part can be compensated for by increasing the distance between two mutually parallel counter-guide surfaces when the respective guide element of the mounting part engages in a straight guide of the adjustment part.

A particularly preferred development of the band part according to the invention is one in which the counter-guide surfaces are formed by two mutually parallel longitudinal walls of the guide element. An increase in the distance between two mutually parallel counter-guide surfaces can then be achieved in a simple manner by increasing the distance between the two mutually parallel longitudinal walls.

The distance expansion can take place, for example, by means of at least one expansion element, which can be brought between the longitudinal walls of the guide element.

In a preferred embodiment, the expansion element comprises an expansion pin or an expansion screw, wherein the expansion pin or the expansion screw can preferably be brought between the longitudinal walls via a bore in the mounting part.

In a particularly preferred embodiment of the band part according to the invention, the guide element is designed in a trough-shaped manner such that its open side is provided facing the fastening wall. The bottom surface of the trough or the surface that connects the two longitudinal walls can then be formed by a surface of the mounting element, which is preferably in the same plane as a contact surface of the mounting element on the adjustment element.

The guide element preferably further comprises at least one intermediate wall running transversely to the longitudinal walls. In order to nevertheless enable an at least partial extension of the distance between the mutually parallel longitudinal walls of the guide element, the at least one connecting wall preferably comprises a slot through which a plane extends that runs parallel to the longitudinal walls.

The slot extends - particularly preferably - from an end of the partition wall facing the fastening wall to the end of the partition wall remote from the fastening wall, i.e. to the bottom surface of the tub. Due to this measure, the distance between the parallel longitudinal walls can be expanded as best as possible using the expansion element.

The band part can be mounted on the fastening wall of the frame or the sash in a particularly simple and particularly precisely positionable manner if - as preferred - the mounting part comprises at least one positioning extension which is suitable for engaging in a hole which opens into the fastening wall . If the positioning extension is also designed like an expansion dowel, fastening of the mounting part and thus of the entire band part is usually already possible by spreading the positioning extension after it has been inserted into the hole and thus creating a non-positive and/or positive connection between the positioning extension and the frame or the wing is effected.

The invention also extends to a hinge band with a band part of the type described above.

An exemplary embodiment of the band part according to the invention is shown schematically in the drawing. Show it: 1 shows a system with this embodiment of the band part according to the invention in a view in the longitudinal direction of a hollow profile with a partially cut band part;

The exemplary embodiment of a band part 1 according to the invention shown in the drawing, with an adjusting part 2, on which a hinge part 3 is integrally formed, which includes a receptacle 4 for a known adjustment bushing of a band bolt, not shown in the drawing. In the adjusting part 2 there are two straight guides 5 in the form of slot-shaped openings 6 which run parallel to one another and perpendicular to the longitudinal axis of the receptacle 4. In the middle between the elongated hole-shaped openings 6 there is a driver element 7. It is bolt-shaped and sits in a bore 8 of the adjusting part 2. It has a threaded bore 9 running transversely to its longitudinal extent, into which an adjusting spindle 10 adapted to it engages . The belt part 1 is part of a system 100.

The adjusting spindle 10 is mounted in a mounting part 11 of the band part 1 so that it can rotate about its longitudinal axis and is fixed in the direction of its longitudinal axis in such a way that its longitudinal axis is aligned parallel to parallel guide surfaces 29, which are formed by longitudinal surfaces 26 of the straight guides 5. For this purpose, the adjusting spindle del 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.

The mounting part 11 further comprises guide elements 16, which pass through the openings 6 over part of the length of the straight guides 5. As a result, the assembly comprising the adjustment part 2 and the hinge part 3 can be displaced in a displacement direction V, which runs parallel to the longitudinal extents of the straight guides 5.

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, which can be part of a wing F or a frame R.

The guide elements 16 are formed on a back 19 of the mounting part 11, which faces a front side 20 of the adjusting part 2 and rests against it when mounted on the fastening wall 17 of the hollow profile 18.

The guide elements 16 each have two mutually parallel longitudinal walls 24, whose sides facing away from one another form counter-guide surfaces 30 which run parallel to the guide surfaces 29 of the adjusting part 2.

Furthermore, 11 positioning extensions 21 are provided on the mounting part. 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. 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 has the fastening wall 17 in a hole

22, but not an inner wall 17a of the hollow profile 18.

The positioning extensions 21 are tubular and have longitudinal slots

23, two of which are arranged in such a way that they are penetrated by a plane E running parallel to the longitudinal walls 24 of the guide elements 16. The positioning extensions 21 thus form intermediate walls 31, which extend in a curved manner between the longitudinal walls 24. Due to the slots 23, which are penetrated by the planes E, the longitudinal walls 24 can be spread open, for example with an expansion screw 25, which is screwed into a positioning extension 21, so that by inserting the expansion screws 25, the distance A between the two counter-guide surfaces 30 of a guide element 16 can be expanded at least in some areas. Due to this measure, the play existing between the guide surfaces 29 of a straight guide 5 and the counter-guide surfaces 30 of a guide element 16 engaging in this straight guide is compensated at least in some areas with the help of an expansion screw 25.

For this purpose, at least the slots 23, which are penetrated by the plane E, extend at least as far as the vicinity of a connecting wall 32 connecting the longitudinal walls 24, which coincides with the rear side 19 of the mounting part 11.

Since the slots 23, which are penetrated by the plane E, also extend to the ends of the positioning extensions 21 remote from the back 19 of the mounting part 11, screwing in the expansion screws 25 not only causes the distance A between two to be expanded, at least in some areas parallel counter-guide surfaces 30, but also a spreading of the positioning extensions, so that the band part is positioned on the fastening wall 17 by screwing in the expansion screws.

The hinge part 1 and thus a hinge part 3, which comprises this hinge part 1, is thus characterized both by a particularly precise and reproducible adjustability in the adjustment direction V, as well as by an easily accomplished and reliable positioning of the hinge part on the fastening wall.

In the embodiment of the hinge part 1 according to the invention shown in the drawing, additional holes 27 are provided in the mounting part 11. They extend through one of the guide elements 16 in tubular extensions 28 within the respective guide element 16. The extensions 28 also have slots which are penetrated by one of the planes E. This ensures that the longitudinal walls 24 of a guide elements 16 can also spread in the area of the extensions 28 in the direction of the longitudinal surfaces 26, so that the long 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 holes open up the possibility of screwing additional fastening screws (not shown in the drawing) into the fastening wall 17 of the hollow profile 18 if this is required in individual cases to achieve the required holding forces on the profile.
