Description

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

In the band known from DE-PS 34 18 138, the hinge pin is mounted in the hinge part in two nested hinge pin bushings, the inner bores of which are arranged eccentrically to the outer circumference by the same amount. By mutually turning the hinge pin bushings, a certain displacement of the hinge pin relative to the hinge part can be carried out, as may be necessary, for example, when assembling doors or windows to bridge manufacturing and assembly tolerances and to cleanly adjust the sash in the fixed frame.

The adjustment amounts perpendicular to the axis of the hinge pin that can be achieved by double eccentric bushings are limited and really only suitable for bridging tolerances within one and the same make. However, there are also cases in which the position of the attachment points of the hinge plates varies to a greater extent is, for example, if different doors or window brands are to be fitted with the same hinge and the different arrangement of the fastening points on the fixed frame and the sash differ more from each other due to the different design.

Attempts have already been made to make the band flaps adjustable in themselves (US Pat. No. 2,839,778). However, new problems arise with the secure fixing of the parts of the hinge to each other and their attachment to the fixed frame or sash.

From DE-GM 17 91 930 an embodiment of an adjustable band is known in which a recess with a rectangular cross section is provided in one of the hinge parts and the band pin comprising a correspondingly flattened guide part in this recess can be moved by hand into different positions and by at Means attacking outside of the hinge part, for example screwing device, can be stuck in a certain position.

Although much larger adjustment paths are possible than with eccentrics, it is very inconvenient that the wing, because the adjustment is done by hand, has to be held during the adjustment. A more sensitive adjustment is very difficult, especially with heavier sashes. The arrangement of the fixing means outside the hinge part is undesirable because it is too easily accessible, disturbs the visual impression of the tape and is a starting point for dirt.

US Pat. No. 2,251,865 shows a hinge corresponding to the preamble of claim 1, in which the adjustment is carried out by screw spindles accommodated in the hinge and no holding of the wing is necessary during the adjustment. However, in order to prevent the guide part from tilting, it requires complex tongue and groove guidance of the same and two screw spindles that are jointly driven via pinions.

The invention has for its object to prevent the tilting of the guide part when adjusting in a simpler manner.

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

The flanges counteract an inclined position of the guide part or the hinge pin in the recess, so that in most cases only a single screw element is necessary.

The flanges can be separate parts connected to the guide part or also integral with it (claims 2, 3).

In order to improve the guiding effect and in particular to achieve a fixing effect in the recess against displacement in the adjustment direction, it is recommended that the flanges according to claim 4 bear against the hinge part under prestress. This preload can be selected so that there is sufficient fixing, but nevertheless a displacement of the guide part in the recess is possible by actuating the threaded element without having to loosen the preload.

The system under pretension can be accomplished according to claim 5 by a two-part design of the guide part, the dimensioning according to claim 6 being able to take place in such a way that when the two parts are tightened "on block", a predetermined pretension suitable for the desired limited fixing effect is present is.

The threaded element can be rotated through a transverse bore of the relevant hinge part and formed by a cap screw (claims 7,8).

In the case of a hinge band, the configuration according to claim 9 can be made. According to claim 10, the flanges can perform an additional function to reduce friction.

The adjustment of the hinge pin in the hinge part according to the invention can take place both parallel to the wing surface to adjust the arrangement of the wing in the clear opening of the fixed frame, as well as perpendicular to the wing surface to cope with different cover dimensions and to adjust the contact pressure of the seals.

When this description refers to "above" and "below" as well as "front" and "rear", this means the belt in its installed position, seen by an observer standing in front of the door or the window.

1 comprises a hinge to be fastened to the fixed frame, which consists of the hinge parts 28, 32, and a hinge to be fastened to the casement, which consists of the hinge part 34. The band flaps consist in all execution examples of sections of extruded aluminum profiles and thus have mutually parallel boundary surfaces above and below. It is fastened with screws. 1, a hinge part divided into two parts 35, 35, designated as a whole by 30, is provided up and down into a guide part 86 which can be displaced in the recess 20 of the hinge part 34 and which has a flange 79 at its lower end which connects the edge of the recess 20 to the Covered underside of the hinge part 34 and there has a covering 81 covering the side of the flange 79 facing the lower hinge part 28, which has good sliding properties and with which the hinge part 34 rests on the upper side of the lower hinge part 28.

At the end of the guide part 86 which projects beyond the upper edge of the hinge part 34, a flange 82 is also attached which overlaps the edge of the recess 20. The presence of in particular the one-piece lower flange 79 stabilizes the guide part 86 in the vertical position, so that for the horizontal adjustment of the guide part 86 in the recess 20 with only one threaded element 22 in the form of a cap screw 30 perpendicular to the axis, the cap screw can be worked can be actuated through the bore 25 in the hinge part 34.

The band according to FIG. 2 is a two-part band and has in the lower band tab 1 a band journal bushing 12 in which the band journal 100 is seated. The guide part 96 in the upper hinge tab 4 is also designed as a sleeve, the outer circumference of which is profiled in accordance with the recess 20 (see FIG. 3) and into which the hinge pin 100 engages from below to over half the height. The guide part 96 has at its lower end a flange 91 which covers the edge of the recess 20 and via which the upper hinge plate 4 transmits the load to the lower hinge plate 1.

At the upper end of the guide part 96, a flange disk 92 is provided which engages over the edge of the recess 20 and can be tightened by means of a screw against the upper end of the guide part 96. The flange 91 and the flange disk 92 therefore bear against the band tab 4 under axial prestress from below and above. This results in in addition to a guiding action which holds the guiding part 96 vertically, a clamping action which is able to hold it in the recess 20 in a certain displacement position. The threaded element 22, which is again designed as a cap screw and passes through the guide part 96 and the upper end of the hinge pin 100 halfway up the hinge tab 4 and rests against the ends of the recess, only needs to serve as a drive for the displacement, while the Determination largely taken over by the flanges 91.92. The dimensioning can take place in such a way that when the guide part 96 and the flange disk 92 abut one another on the surface 93, just the correct pretension has been achieved, which results in a sufficient fixing, but still permits displacement by actuating the threaded element 22.

This mode of operation is also realized in the hinge band of FIGS. 4 and 5. As in the exemplary embodiment in FIG. 1, the hinge pin comprises two parts 35, 35 which are arranged in the lower and upper hinge parts 28, 32. In the middle hinge part 34, the recess 20 is provided with the guide part 106, which in turn is designed on its outer circumference in accordance with the recess 20 and forms a bush in its lower region, into which the lower hinge pin part 35 engages and a radial flange on its lower edge 91, which corresponds to the corresponding flange in Fig. 2.

In the embodiment of FIGS. 4 and 5, however, the flange disk 92 is formed on a somewhat deeper sleeve-like part 94, in which the upper hinge pin part 35 engages in the manner shown in FIG. 4 can. The sleeve-like part 94 has the same outer cross section as the guide part 106 and cooperates with the guide. The parts 94 and 106 are pulled against each other by means of a screw 83 in the axial direction until they rest on the separating surface 94, as a result of which the guide part 106 is fixed.
