Description

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

Such a band is known from EP-A2 460 620. The further journal bearing here has a connecting part which nestles into corresponding recesses in the fastening part and is also fastened when the fastening screws of the fastening part are tightened. The attachment of a separate fastening screw for the further journal bearing is not possible because such a fastening screw would have to pass through the journal bearing from the front or else made special designs of the same necessary in which the fastening screw would be visible or even accessible from the front, which is not desirable. The complicated shaping caused by the nesting reduces the possible manufacturing processes of the strip parts to the die casting process. Although the known band has the advantage that the lower part of the frame band with the fastening part and the lower journal bearing can also be used as a frame band part of a so-called two-part band, in addition to a hinge band, the frame band part must be used immediately as a whole, ie with, as a hinge band lower and upper pivot bearing, which makes it difficult to hang the wing because this with its considerable weight with the hinge part of the wing hinge part exactly between the Pin bearing must be practiced in order to be able to insert the hinge pin.

The invention has for its object to make a generic tape more stable and easier to handle while maintaining its dual usability.

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

The fastening part is therefore no longer nested with the further journal bearing, but an additional holding part is provided, which can be attached to the frame independently of the fastening part and has at least one fastening screw of its own. It is fixed in the horizontal plane on the fastening part, so that the later alignment of the bores of the two journal bearings is ensured. It is important for practical handling that the further, i.e. the upper pivot bearing can only be attached after the wing has been hooked in, which means that the wing can be hooked in from above like a two-part hinge, which is much easier than inserting the guide band between the pivot bearings of a hinge band because the hinge pin has a leading effect at an early stage results in lowering on the journal bearing.

The lower part of the frame hinge part with the fastening part and the lower hinge bearing can be used on its own for a two-part hinge. But if it is supposed to be a hinge, it can be hooked in as easily as with a two-part hinge and the upper journal bearing can be added later, whereby it is at least given its own fastening screw and a correspondingly stable fixing.

The subsequently producible connection of the upper journal bearing to the holding part is advantageously carried out via a dovetail connection according to claim 2.

DE-OS 37 05 131, taken separately, from a fastening part and thus connectable via a dovetail pin bearing of a frame hinge part. However, no separate holding part is provided here, the dovetail goes through the entire height of the frame hinge part and the idea of using one and the same hinge part for two-part hinges and hinges does not matter.

In order to achieve a smooth outer contour of the band, it is recommended according to claim 3 to give the holding part and the further journal bearing the same height.

In order to secure the further journal bearing on the holding part, a locking member according to claim 4 is recommended, which can be designed in particular as a locking pin, smooth or with thread (claims 5, 6 and 7).

The locking member can also be realized as a locking ball or index pin (claims 8 and 9).

The cover plug which closes the hinge pin recess upward can be in one piece with the upper hinge pin bushing as shown in claim 10.

The formation of the holding part and the fastening part on the mutually facing surfaces and the fixing of the two parts to one another in the horizontal plane can be carried out in the manner set out in claims 11 to 14.

If in the following from "vertical", "horizontal", "above" or "below", it always refers to the tape in the installed position.

The band designated 100 as a whole in FIG. 1 is designed as a hinge band with a frame band part 10 and a wing band part 20. The frame hinge part 10 is intended for attachment to a mounting surface 1 of a frame, which is parallel to the frame plane. The mounting surface 1 is thus vertical and perpendicular to the plane of the drawing in FIG. 1. The wing hinge part 20 is shown with the wing open by 90 °. 1 is parallel to the plane of the drawing.

The frame hinge part 10 comprises a strip-shaped vertical fastening part 2 of rectangular cross section, which bears with the rear side 4 on the mounting surface 1 and in the exemplary embodiment contains two bores 3 one above the other for fastening screws 5, which are indicated in FIG. 1 only by their dash-dotted center line, but also are designed like the fastening screw 5 shown above in FIG. 1.

Below the actual fastening area 6, in which the fastening screws 5 are seated, the lower journal bearing 7 projects from the fastening part 2, which has a recess 9 for the hinge pin bushing 11 at a distance from the front side 8 of the fastening part 2 the eccentric bore 13 of the hinge pin 12 is arranged. The hinge pin 12 thus extends vertically and parallel to the fastening part 2. Against the hinge pin bushing 11, a threaded piece 15, screwed into a thread 14 at the lower end of the recess 9, acts in its lowest position, by means of which the hinge pin bushing 11 is in its vertical position can be adjusted.

Between the bores 3 for the fastening screws 5 and in the region of the lower journal bearing 7 there are additional retaining pins 16 in the fastening part 2, which engage in corresponding bores of the mounting surface 1 perpendicular to the mounting surface 1 and in the transmission of the the band 100 exerted forces and participate in its positioning.

The fastening part 2 ends at the top in a horizontal, flat end surface 17. A holding part 18, which continues the fastening part 2, is provided, which has a flat lower end surface 17 'and essentially the same cross section, but has a horizontally projecting dovetail design 19, which can be used for Axis 21 of the hinge pin 12 extends in parallel sliding direction over the height of the holding part 18. With a corresponding dovetail 22, an upper journal bearing 27 can be inserted into the dovetail configuration 19 from above, which has approximately the same height as the holding part 18 and the lower journal bearing 7.

The upper journal bearing 27 also contains a recess 23 in which an eccentric hinge pin bushing 24 is arranged, which receives the upper end of the hinge pin 12 projecting upward above the wing hinge part 20. The hinge pin bushing 24 has at the lower end, like the hinge pin bushing 11 at the upper end, an extension 25 which engages in a corresponding extension 26 of the recess 23. The height of the extensions 25, 26 corresponds to the adjustment height that can be considered, which can be achieved by actuating the threaded piece 15. The extension 25 should improve the power transmission in the critical area and optically result in a larger diameter.

At the upper end, the recess 23 is closed by a threaded plug 28, which leaves a distance corresponding to the adjustment stroke from the upper end of the hinge pin bushing 24.

In the exemplary embodiment, the holding part 18 has a single fastening screw 5 of its own. Additional holding pins 16 are provided above and below the fastening screw 5, as is the case with the fastening part 2.

In order to keep the holding part 18 in alignment with the fastening part 2 in the horizontal plane, a parallel to the hinge pin 12 is in both parts 2.18 engaging pin 29 is provided.

The design of the wing hinge part 20 is only important insofar as it has a hinge part 30 with a continuous recess 31 in which a hinge pin bushing 32 is arranged, through which the hinge pin 12 passes. Connected to the hinge part 30 is a fastening part 33 lying flat on the wing surface, which contains adjustment mechanisms (not shown) for adjusting the horizontal position of the wing. The wing hinge part 20 is delimited by horizontal upper and lower levels 34, 35.

When assembling the band 100, the fastening part 2 with the lower journal bearing 7 is first fixed on the mounting surface 1 by tightening the two fastening screws 5 shown by their dash-dotted center line.

If the band 100 is to be used as a so-called two-part band, it remains with it. The wing with the wing hinge parts 20 is hung from above onto the hinge pin inserted into the recess 9 of the lower journal bearing 7.

However, if the band 100 is to be used as a hinge band, the holding part 18, which is fixed by the fastening screws 5, the holding pins 16 and the pin 29, has been attached after the mounting of the fastening part 2 with the lower journal bearing 7 above the fastening part 2. The wing with the wing hinge parts 20 is now hung exactly on the now longer hinge pin 12, as was the case with the two-part hinge. Only then is the further, ie upper journal bearing 27, united with the holding part 18 by pushing it in along the dovetail connection 19, 22. Holding part 18 and journal bearing 27 have the same height. When the correct position according to FIG. 1 is achieved, the radial locking pin 36 is inserted from the inside of the recess 23, which engages from the upper journal bearing 27 into the holding part 18 and secures the upper journal bearing 27 in the direction of displacement. The adjustment in the horizontal direction is then carried out by actuating the adjustment mechanisms of the wing hinge part 20 through the front opening closed by the stopper 37 and the adjustment in the vertical direction by actuating the threaded piece 15.

All parts, with the exception of the plastic bushings 11, 24 and 32 which hold the hinge pin 12, are designed in such a way that they can be extruded from a suitable aluminum material and produced by sawing off. Only when the two journal bearings 7, 27 are not connected in one piece can the extensions 26 for the thickened ends 25 of the journal journals 11, 24 be produced. The thickened ends 25 have an optical meaning in that they conceal the "lean" hinge pin 12 in the vertical space required for a height-adjustable hinge strap and also conceal the different height of the sash hinge part 20 relative to the hinge hinge part 10. The separation of the holding part 18 from the fastening part 2 allows the different use of the fastening part 2, which is therefore both for a so-called "two-part" band without an upper journal bearing 27 and in the manner shown for a so-called three-part band, i.e. a hinge strap, can be used without change. In addition, the separation simplifies the hanging of the wing in that it is hung on the hinge pin 12 with the upper pin bearing 27 initially omitted and the upper pin bearing 27 can only be retrofitted.

3 to 7, functionally corresponding parts are provided with the same reference numbers as in FIGS. 1 and 2.

In the individual view of FIG. 3 reproduced in the upper area of FIG. 1, two changes have been made compared to FIG. 1. One change relates to the cover plug 28 ', which here has no thread, but rather peripheral ribs 51, with which it is fixed in the hinge pin recess 23. The other change relates to the design of the radial locking pin with which the upper journal bearing 27 can be fixed vertically on the neck part 18 in its determination position: the locking pin is designed here as a threaded pin 36 'which can be actuated from the inside of the recess 23 before the cover plug 28' is inserted.

FIG. 4 shows a view corresponding to FIG. 3, in which the locking member at the upper end of the further journal bearing 27 and the holding part 18 is not designed as a pin, but rather as a detent ball 40, which is in a blind hole 38 on the rear side 39 of the additional journal bearing 27 arranged and backed by a resilient plastic part 47. The detent ball 40 projects in the force-free state by less than its radius from the rear side 39 without falling out, and snaps when the further journal bearing 27 is inserted into the dovetail connection 19, 22 under the spring action of the plastic part 47 into a recess 41 formed by a bore the adjacent side of the holding part 18. When the further journal bearing 27 has reached its end position, the bores 38, 41 are aligned with one another.

In the embodiment according to FIG. 5, a first change compared to that according to FIG. 1 is that the cover plug 28 'and the hinge pin bushing 24' of the upper journal bearing 27 are combined to form an integral part 48. Since the part 48 assumes a position that is invariable in height, a precaution must be taken that enables the height of the wing hinge part to be adjusted. The "extension" 25 of FIG. 1 is replaced in this embodiment by an extension ring 49, which is height-adjustable in relation to the part 48 when the wing hinge part 20 is adjusted, but otherwise assumes the function of the extension 25.

In the embodiment according to FIG. 5, the locking member is formed by an index pin 42 which is guided in a bore 43 radial to the hinge pin 11 at the upper end of the further journal bearing 27, which extends into the hinge pin recess 23. When the further journal bearing 27 is in position, a recess 44 formed by a bore is aligned with the bore 43 on the other Pin bearing 27 facing side of the holding part 18. When the additional pin bearing 27 is installed, the index pin 42 is seated in the bore 43 and initially does not protrude beyond the rear side 39 of the additional pin bearing 27, while it projects into the hinge pin recess 23 with the other end. When the further journal bearing 27 is brought into position, the part 48 is pressed in from above and thereby moves the index pin 42 according to FIG. 5 to the left so that it engages in the recess 44 and locks the parts 27 and 18 together in the vertical direction. The index pin 42 is prevented from retreating by the part 48 in the locking position.

5 and 6 a modified fixing of the holding part 18 on the fastening part 2 is shown compared to FIG. 1. Instead of the fixing pin 29, a molded body 45 is provided here in the form of a double cylinder, the two individual cylinders 45 'and 45' 'of which are connected to one another in parallel and along one jacket region. The shaped body 45 engages in two blind bores 46 ′, 46 ″ parallel to one another and to the end surfaces 17, 17 ′ and perpendicular to the rear side 4 on the rear side 4 of the fastening part 2 or the holding part 18, which define the end surfaces 17, 17 ′. cut. The shaped body 45 and the blind bores 46 ', 46' 'thus have the cross section of an "8", so that when the shaped body 45 is inserted, the holding part 18 is fixed both parallel to its end face 17' and perpendicularly to the fastening part 2.

Instead of the shaped body 45, a disk spring 37 (also called a Woodruff wedge) can be provided, the disk plane of which is parallel to the axis of the hinge pin 12 and perpendicular to the rear side 4. The disc spring 37 engages in a corresponding semicircular recess in the parts 2 and 18 and fixes them to one another parallel to the end faces 17, 17 ', but without causing a connection in the axial direction of the hinge pin 12.
