Abstract

The invention relates to a strip for doors, windows or the like. The hinge component of the frame strip component (10, 10') or the leaf strip component (20, 20') is provided with a cross-sectional surface which is smaller than the cross-sectional surface of the other strip component in such a way that the outer circumference of the cross-section pertaining to the first strip component is smaller than the circumference of the cross-section pertaining to the other strip component at least in the direction of adjustment. Furthermore, at least one covering sleeve (40) is provided which at least partially encompasses the hinge component of the at least one strip component. Said sleeve can be fixed in relation to the at least one other strip component. The inner cross-sectional surface of the covering sleeve (40) is dimensioned in such a way that a gap (43) remains between the inner lateral surface (42) thereof and the outer circumference (16) of the surrounding hinge component. The width of the gap is at least as great as the path of adjustment. Adjustment of said strip is possible without an externally visible mismatch of the strip components in relation to each other.

D - 41189 Mönchengladbach Tape for doors, windows and the like

The invention relates to a tape of the type corresponding to the preamble of claim 1.

Such hinges are used for the pivotable fastening of a sash that optionally closes an opening to the component that delimits the opening, usually a frame. They comprise at least one frame hinge part that can be connected to the fixed component, a sash hinge part that can be connected to the sash, and a hinge bolt that at least partially passes through the two hinge parts and whose longitudinal axis defines the pivot axis of the hinge.

In order to adjust the sash in the opening, it is necessary to be able to move and determine the position of the fastening points on the front surfaces of the fixed component or the sash in the longitudinal direction and perpendicular to the longitudinal direction of the hinge bolt.

In the simplest case, this is done by attaching the hinge parts to the fixed component or

the sash in a manner that allows relative displacement after loosening the fastening screws.

If the fastening screws are accessible when the sash is closed, adjustment can be carried out easily by tightening the fastening screws when the sash is closed. However, the disadvantage is that this type of arrangement of the fastening screws does not provide any protection against dismantling of the closed sash by unauthorized persons.

It is therefore also known to arrange the fastening screws in such a way that they are only accessible when the sash is open. However, this makes adjustment considerably more difficult because the sash cannot first be closed and then fixed in its adjusted position; instead, an attempt must be made to fix the sash in the adjusted position when it is open.

In order to avoid these disadvantages, it is known, for example from DE 40 22 532 C1, to provide a straight guide in one of the hinge parts, on which the hinge bolt can be displaced and fixed perpendicular to its axis. In other words, this hinge part can be displaced in a direction perpendicular to the longitudinal direction of the hinge bolt relative to the other hinge part, so that the sash can be adjusted in the opening without loosening the fastening screws.

Although this type of adjustment can avoid the problems associated with loosening the fastening screws, the disadvantage is that the adjustment is accompanied by an offset of the band parts relative to each other, which can significantly disturb their external appearance.

The invention is therefore based on the object of creating a hinge for doors, windows or the like, in which adjustability is guaranteed without the disadvantages explained above.

In the band according to the invention, the hinge part of at least one of the two band parts is smaller in cross-section than the hinge part of the other band part. The band part with the smaller cross-section is provided with a cover sleeve which can be fixed in relation to the other band part. The sleeve and the one band part are dimensioned such that a gap remains between the inner wall of the sleeve and the outer surface of the hinge part of the one band part, the width of which is at least as large as the adjustment path of the band bolt.

Since it is thus possible to move one part of the band relative to the band bolt without changing the outer contour of the band defined by the cover sleeve, the adjustment process has no effect on the optical appearance of the band.

The movement of the hinge pin in the hinge part transversely to its longitudinal direction can be carried out in a known manner, for example by means of an adjusting spindle running perpendicular to the longitudinal axis of the hinge pin, which actuates a guide bushing that receives the hinge pin in an elongated longitudinal recess in the hinge part, or by means of an adjusting spindle running parallel to the longitudinal axis of the hinge pin, which actuates a sliding block that engages with a helical groove in the guide bushing. If the adjusting spindle runs perpendicular to the longitudinal axis of the hinge pin, the cover sleeve preferably has at least one recess through which the adjusting spindles are accessible for the purpose of actuation.

The cover sleeve can preferably be attached to the other band part by means of fastening means provided on its front side facing the one band part.
5

Preferably, the fastening means and the cover sleeve are designed in such a way that they form a locking connection for securing the cover sleeve. For this purpose, the fastening means can have a fastening component which radially surrounds the hinge bolt and which has at least one recess on its outer surface into which at least one locking projection provided on the inner surface of the sleeve can be brought into engagement.

The cover sleeve preferably has a cover cap on its free, front end that at least essentially closes the front end. This measure gives the cover cap a homogeneous appearance that is barely distinguishable from a hinge part, and on the other hand the means for transverse adjustment of the hinge bolt in the hinge part are reliably protected from the ingress of contamination.

If the cover cap has at least one recess on its outer surface into which at least one locking projection provided on the inner surface of the cover sleeve can be selectively engaged, the latter can be designed symmetrically in the sense that it is possible to place the cover sleeve with one or the other end towards the fastening means.

If the hinge additionally has a device for adjusting the height of the at least one sash hinge part via the at least one frame hinge part in the direction of the longitudinal axis of the hinge bolt by an adjustment path referred to below as "vertical", the cover sleeve and the

The cover cap is preferably designed in such a way that there is a distance between the side of the cover cap facing the hinge bolt and the hinge part which corresponds at least to the length of the vertical adjustment path.
5

This measure also makes it possible to move the hinge parts relative to one another in the longitudinal direction of the hinge bolt without this leading to the formation of such gaps that are visible from the outside or a change in the visible gap dimensions.

In the embodiments described so far, only one of the hinge parts is covered by cover sleeves, so that the hinge part of the other hinge part is visible. However, it is also possible to provide this hinge part with a cover sleeve, the outer contour of which is then preferably adapted to the outer contour of the cover sleeves of the hinge parts of one hinge bolt. It goes without saying that these cover sleeves with the hinge parts do not have to have a gap that corresponds at least to the adjustment path. The fixing can be carried out in the same way as that of the other cover sleeves.

Another fastening option is to make the inner contour of the relatively thin-walled cover sleeve smaller than the outer contour of the hinge part, so that the sleeve can be pushed or clamped by expanding in the elastic area of the base material.

This embodiment of the band according to the invention has the advantage that its outer contour and/or color can be adapted to the respective requirements and needs by exchanging the sleeves. This means that different band parts that differ from one another in terms of their shape and color are no longer required, but rather the provision of a technically functional

·

The use of a functionally designed band and differently shaped and colored cover sleeves allows the band to be optically customized. This can reduce production and storage costs.

other embodiment (section IX-IX in Fig. 1) and

Fig. 10 a cover sleeve and a cover cap in individual representations.

The embodiment of a hinge designated as a whole with 100 in Figs. 1 to 4 comprises a frame hinge part 10 attached to the side of a fixed frame 1 facing a sash 2 and a sash hinge part attached to the side of the sash facing the frame 1

20. The hinge parts 10,20 can be pivoted relative to one another about a hinge axis 9 formed by a hinge pin 8 (Fig. 4).

Screws and fixing pins (not shown in the drawing) are used to fasten both the frame hinge part 10 and the sash hinge part 20. The frame 1 and the sash 2 do not abut directly against each other, but form a rebate with a shadow groove 7 on the visible side (Fig. 3).

The sash hinge part 20 is equipped with means for displacing and fixing the hinge bolt in a direction transverse to its longitudinal axis 9, which in the embodiment shown in Fig. 4 comprises a bearing bush 11 which radially surrounds the hinge bolt 8. This has a longitudinal toothing 12 on its outer surface, which engages with a counter toothing, which in turn has an inner diameter which exceeds the outer circumference of the bearing bush 11 in the transverse direction to the longitudinal axis 9. An adjusting spindle 14 is provided for adjusting the hinge bolt 8 relative to the sash hinge part 20, which

engages in a threaded hole 15 which runs in the adjustment direction and is incorporated into the hinge bolt and is rotatably mounted in the sash hinge part in a fixed manner in the adjustment direction.

The hinge part 13 of the sash hinge part 20 has an outer diameter 16 which is smaller than the outer diameter 17 of the hinge part 18 of the frame hinge part 10. The hinge part 13 of the sash hinge part 20 is surrounded by a cover sleeve, designated as a whole by 40, the outer peripheral surface 41 of which is aligned with that of the hinge part 18 of the frame hinge part 10, which in Fig. 4 is also provided with a cover sleeve 50.

The cover sleeve 40 and the outer diameter 16 of the hinge part 13 are dimensioned such that between the inner surface 42 of the cover sleeve 40 and the outer diameter 16 of the hinge part 13 there is a gap 43 whose width corresponds at least to the adjustment path in the transverse direction indicated by the arrow P. In Fig. 4 the hinge bolt 8 is in its middle position so that the gap 43 has the same size on both sides of the hinge part 13. It is understood that the conditions change when the hinge bolt has been displaced in the transverse direction P.

The front end of the cover sleeve 40 shown at the top in Fig. 4 is closed by a cover cap 44.

The cover sleeve 40 further has a lateral recess 46 through which the adjusting spindle 14 is accessible.

The hinge part 18 of the frame hinge part 10 comprises a central longitudinal recess 21, which serves to accommodate a bearing bush 19 for the hinge bolt 8, which can be moved in the longitudinal direction 9. At its end shown in Fig. 4 below, the central longitudinal recess 21 merges into a

·

&bull; *

larger inner diameter threaded bore 2 2, into which a spindle 2 3 engages, which can be actuated from the lower end of the threaded bore 22 and on which the bearing bush 19 is supported. The hinge 100 can be adjusted in the longitudinal direction 9 by screwing the spindle 2 3 further into or out of the threaded bore 2 2, since this changes the relative position between the bearing bush 19 and the hinge part 18 and thus also between the hinge bolt and the hinge part 18 of the frame hinge part 10.

To secure the cover 40, the cover has a plurality of locking lugs 25 on its front end facing the frame band part 10, which protrude beyond its inner circumference (see Fig. 10) and which engage in a circumferential groove 24 provided on the upper front end of the bearing bush 19 according to Fig. 4. The cover sleeve 40 can be removed or fitted by elastic deformation of the locking lugs 25.

As can also be seen from Fig. 10, the cover sleeve 40 also has locking lugs 25' at its upper end according to Fig. 10, the dimensions and arrangements of which correspond to those of the locking lugs 25. Accordingly, the cover cap 44 has an extension 45 which can be displaced into the interior of the cover sleeve 40 and which comprises an all-round groove 46 whose dimensions correspond to the all-round groove 24.

The belt shown in Fig. 5 to 7 and designated as a whole with 200 corresponds in its function essentially to that shown in Fig. 1 to 4, components with the same function are provided with the same reference numerals, but supplemented by a '. If they are not specifically mentioned below, in order to avoid repetition, reference is made to the explanations on the

corresponding components. However, the frame hinge part 10' comprises an upper hinge part 26 and a lower hinge part 27, between which the hinge part 28 of the sash hinge part 20' is arranged. The latter is provided with means 30' for adjusting the hinge bolt 8' transversely to its longitudinal direction 9', which can be technically implemented in a manner explained with reference to Fig. 4 or in another manner. By way of example, reference is made at this point to Fig. 8, in which the means 30' comprise an adjusting spindle 31 extending parallel to the longitudinal axis 9', which displaces a sliding block 32 in the direction 9', which engages in a helical groove (not shown in the drawing) provided in the outer peripheral surface of a bearing bush 33 surrounding the hinge pin and pivots the bearing bush 33 about a pivot axis formed by an extension 34 engaging in the interior of the hinge part 28 with lateral displacement.

As can be seen in particular from Figs. 6 and 7, the band 200 also has a spindle 23', with the aid of which the band bolt 8' is moved in a manner corresponding to that of the embodiment shown in Figs. 1 to 4.

The hinge parts 26, 27 of the frame hinge parts 10' are smaller in their diameters 35, 36 than the sash hinge part 20', so that cover sleeves 40' together with cover caps 44' are again present, the designs and functions of which correspond to those explained with reference to Fig. 10.

In contrast to the band 100 shown in Fig. 1 to 4, the device 30' for adjusting the band bolt 8' in the transverse direction is not in the band part which has the smaller outer cross section and is connected to the cover sleeve.

se 40, but in the intermediate sash hinge part with a larger cross-section. Therefore, the cover sleeve is not attached directly to the bearing sleeve 19', but to a fastening ring 35. This has a radial extension 36 which engages in the central longitudinal recess of the sash hinge part 20'. On its sides facing the frame hinge parts 10' there is a radial extension 36 whose outer diameter almost corresponds to the outer diameter of the hinge part 28 of the sash hinge part 20' and which has the all-round groove 24' for attaching the cover sleeve 40'. The fastening ring 35 has a central recess 37 for the hinge bolt 8' to pass through, which is widened in the direction of the adjustment path P in order to enable the hinge bolt 8' to be moved transversely.
