Abstract

The adjustable door or window hinge allows the pivot axis to be adjusted in a straight line relative to the door frame in a direction perpendicular to the plane of the door frame and relative to the door in a direction parallel to the plane of the door. For this purpose, there are elongate perforations which are arranged crosswise in the hinged leaves and in each of which a bearing bush can be mounted in different positions by means of axial grooves and axial ribs.

Description

The invention relates to an adjustable door or window hinge comprising (a) a first profile body (band blade) having attaching means for attaching the first profile body at a door or a window frame having an aperture extending in an axial direction , (b) a second profile body (band blade) having attaching means for attaching the second profile body to a door or a window having an aperture extending in an axial direction and substantially aligned with the aperture of the first profile body, (c) a first bearing bush arranged to be introduced into the aperture of the first profile body in different positions and having a bearing bore the position of which relative to the first profile body is variable by choice of one of the said positions, (d) a second bearing bush arranged to be introduced into the aperture of the second profile body in different positions and having a bearing bore, the position of which niJ$i relative to the second profile body is variable by choice of one of said positions, * . and (e) a pivot pin guided ion the bearing bores of the first and the second bearing bush, for articulated connection of the two profile bodies.

With such door hinges it is desirable to enable adjusting the position of the pivot axis within certain limits in order to ensure the door or the window to be opened and closed without jamming.

In a prior art door hinge the hook is located fixedly in an aperture of the first lower profile body to be fixed to the door frame. The aperture of the second profile body to be fixed to the door has a substantial ly circular cross section provided with four axial grooves mutually angularly spaced by 90Q. A potshaped bearing bush is inserted into this aperture of this second profile body. This bearing bush has a substantially cylindrical outer peripheral surface provided with four axial ribs mutually angularly spaced by 90°. The bearing bore of the bearing bush is, located eccentrically with respect to the outer peripheral surface. In this way the pivot axis determined by the axis of the bearing bore of the bearing bush ean be adjusted relative to the door by inserting the bearing bush into the aperture of the second profile body in one of four different positions. In a known arrangement a second similar bearing bush is inserted into the aperture e> / of the first profile body such that the position of the pivot axis also can be adjusted relative to the door frame (German Offenlegungsschrift 30 44 674 and German Auslegeschrift 15 59 987, German Gebrauchsmuster 73 14 035 and German Gebrauchsmuster 72 20 245).

The possibilities are limited for adjustment using * rotatable bearing bushes having eccentric bearing bores. Therein the axis of each bearing bore is displaced along Cl· a cylindrical surface such that, for example, a displacement perpendicular to the plane of the door or the window is positively combined with a displacement parallel to this plane.

FR-A=2 145 891 describes an arrangement permitting independent adjustment in two mutually perpendicular directions. Therein, however, the pin which is mounted at one of the two mutually displaceable members, for example, the lining as shown in Figure 7 of FR-A-1 145 891 , is displaceably but not rotatably mounted. This adjustable mounting sf the pin is effected by frictional engagement: the pin is clamped by means of a collar and a nut and washer.

FR-A-2 230 223 shows an arrangement containing a pin which is fixedly mounted at the lining. The pin determines the pivot axis about which the door can be pivoted. There is only provided a displacement perpendicular to the plane of the lining and the door in order to enable compensation for different thichnesses.

It is the object of the invention to provide an adjustable door or window hinge wherein the adjustment of the pivot axis perpendicular the the plane of'the window or the door can be effected independently of adjustment parallel to this plane. t ·» A further object of the invention consists in Increasing the available adjustment range.

, According to the invention this object is achieved in that (f) the aperture of the profile body has two opposite inner surfaces extending in a first direction at a substantially constant distance from each other, (g) axial grooves are provided side-by-side at equal distance in the opposite inner surfaces of the aperture of the first profile body, (h) the first bearing bush as opposite outer surfaces the dimensions of which in the said first direction are smaller than those of the inner surfaces of the aperture of the first profile body, (i) the first bearing bush has axial ribs side-by-side at equal distances on its opposite outer surfaces such that they are arranged to be selectively pushed into different axial grooves of the first profile body, and thus the first bearing bush is stepwise adjustable in the said first direction, (j) the aperture of the second profile body has two opposite inner surfaces extending in a second direction perpendicular to the first direction at a substantially constant distance from each other, (k) axial grooves are provided side-by-side at equal distances in the opposite inner surfaces of the aperture of the second profile body, (l) the second bearing bush has opposite outer surfaces the dimensions of which in the said second direction are smaller than those of the inner surfaces of the aperture of the second profile body, and (m) the second bearing bush has axial ribs side-by-side at equal distances on its opposite outer surfaces such that they are arranged to be selectively pushed into different axial grooves of the second profile and thus the second bearing bush is stepwise adjustable in the said second direction.

Thus, according to the invention, the adjustment is not effected by means of ah eccentric but by means of a straight displacement of the bearing bushes in elongated apertures, one of the bearing bushes being displaceable in one direction and the other one in a direction crosswise thereto. Therein one of the adjusting movements can be effected perpendicular to the plane of the window or of the door whereas the second adjusting movement is effected in a direction perpendicular thereto, that is parallel to the plane of the window or the door.

Constructional developments of the invention are subject matter of the dependent claims.

An embodiment of the invention will be described hereinbelow in further detail with reference to the accompanying drawings: Fig. 1 is an exploded perspective illustration of an adjustable door or window hinge.

Fig. 8 shows an associated side view.

Fig. 9 shows an end view of the bearing bush as viewed from the bottom in Fig. 8.

Fig.10 shows a partially sectional side view of the pin constructed as a safety pin in a door or window hinge.

The adjustable door or window hinge contains a first profile body 10 (band blade) having attaching means 12 for attaching the first profile body 10 to a door or a window frame 14. The first profile body 10 has an aperture 16 extending in an axial direction. The door or window hinge further contains a second profile body 18 (Band blade) having attaching means 20 for attaching the second profile body 18 to a door or a window 22. The second profile body 18 has an aperture 24 extending in an axial direction and The aperture 24 of the second profile body 18 is also elongated and aligned with a second direction crossing the first direction (roughly parallel to the paper plane of Fig. 1). The second bearing bush 30 can be retained in the elongated aperture 24 of the second profile body 18 in different positions spaced from each other in the second direction. This permits adjustment to the right and to the V left in Fig. 1 without affecting the adjustment to the front and to the rear in Fig. 1. Furthermore, relatively large displacements can be achieved.

In the illustrated preferred embodiment, the aperture 16 of the first profile body 10 has two inner surfaces 36 and 38 facing each other and extending in the first direction at a substantially constant spacing from each other. Axial grooves 40 and 42 (Fig. 6) are respectively provided in juxtaposition and at equal spacings to each other in the opposed inner surfaces of the apertures 16 in the first profile body 10. The first bearing bush 26 comprises opposite outer surfaces 44 and 46 having dimensions which are smaller in said first direction that the dimensions of the inner surfaces 36, 38 of the aperture 16 of the first profile body 10. The first bearing bush 26 has axial ribs 48 and 50 in juxtaposition and equal spacings to each other on its respective opposite outer surfaces 44 and 46 such that they are selectiveley insertrable into different axial grooves 40 and 42, respectively, of the first profile body, and thus the first bearing bush 26 is stepwisely adjustable in said first direction.

The aperture 24 of the second profile body 18 has two inner surfaces 52 and 54 facing each other and extending in the second direction at a substantially constant spacing from each other. Axial grooves 56 and 58 (Fig. 4) are respectively provided in juxtaposition and at equal spacings to each other in the opposed inner surfaces 52, 54 of the aperture 24 of the second profile body 18. The axial grooves 56, 58 correspond to the axial grooves 42 and 40 in the inner surfaces 36 and 38, respecti vely. The aperture 24 has the same profile as the aperture 16, if is just offset by 90°. This profile corresponds to the profile illustrated at an enlarged scale in Fig. 6. The second bearing bush 30 contains opposite outer surfaces 60, 62 (Fig. 4) having dimensions in said seeond direction smaller than the dimensions of the inner surfaces 52, 54 © of the aperture 24 of the second profile body 18» The second bearing bush 30 has axial ribs 54, 66 (Fig. 4 in juxtaposition and at equal spacings to each other on its opposite outer surfaces 60, 62 such that they can be selectively inserted into different axial grooves 56, 58 of the second profile body 18, and thus the second bearing bush 30 is stepwisely adjustable in said second direction.

The spacings of the axial ribs 48, SO and 64, 66, respect!vely, are equal to the spacings of the axial grooves 40, 42 and 56, 58, respect!vely„ At unchanged orientation of the bearing bushes in the apertures, the bearing bushes can be displaced in steps which correspond to the spacing between adjacent axial ribs and axial grooves, respectively. These spacings cannot be smaller than a predetermined extent for constructional reasons. A finer adjustment by steps each having half the distance between the axial ribs and the axial grooves, respectively, can be achieved in the following manner: The axial grooves 40 in one of the inner surfaces 36 of the aperture 16 of the profile body 10 are offset from the axial grooves 42 in the other opposite inner surface 38 by half a spacing. Correspondingly, the axial ribs 48 on the one outer surface 44 of the bearing bush 26 are offset by half a spacing from the axial ribs 50 on the other opposite outer surface 46. Thus, by inserting the bearing bush 26 in an angular position offset by 180° the axis of the bearing bore 28 can be adjusted by a step corresponding to half the spacing between the axial grooves and the axial ribs, . . „ ft respectively* ¢.

The first profile body 10 has a block 68 containing the aperture 16 ..which block 68 is adjoined by plate 70. 1 Centering pins 101 (Fig. 3) can be pressed into the block 68. By means of these centering pins the precise position of the hinge sleeve can be fixed. The hinge sleeve is fixedly threadably connected to the door or window frame by means of screws 72» Correspondingly the profile body 18 has a block 74 which is adjoined by a plate 76. Two centering pins 78, 80 (Fig» 2 and Fig. 4) can be pressed into the plate 76, by means of which centering pins the position of the hinge sleeve on the door or the window can be determined. After the hinge sleeve has been fixed in precise position, the hinge sleeve is attached to the door or window by means of screws 82. The screws 82 are covered by a plate 84, which is insertable into guide means of the plate 76. The plate 84 is clamped by means of a threaded pin 86.

As can be seen from Figs. 7 to 9, the bearing bushes are formed by pot-shaped plastic parts 87 provided with a flange 87.

The pin 34 consists of two parts 88 and 90. The part 88 has a blind bore 92. The part 90 has a pin projection 96 of reduced diameter and knurled at 94. This projection is press-fi tted into the bore 92. An annular disc 98 of metal is held between the end face 0 f the part 88 and the annular shoulder of the part 90 formed around the pin projection 96» The annular disc 98 prevents the pin from being knocked out and thus offers protection against unauthorized opening of the door or the window on the side of the door or window hinge.

As can be seen from Fig. 5, using the herein described arrangement it is possible to -displace the pivot axis in from a zero position in two coordinates in all directions by three millimeters.
