Description

The invention relates to a mounting plate for a hinge, preferably a furniture hinge, consisting of a base plate and an intermediate plate that is adjustable relative to this, which can be connected to the base plate in different setting positions and on which a conventional hinge arm is fastened.

From DE-A-34 26 672 a generic mounting plate is known.

To compensate for unavoidable manufacturing tolerances and assembly inaccuracies, it is desirable that furniture hinges can be adjusted after assembly in such a way that the hinges are adjustable in the depth of the furniture, in the lateral direction and, if possible, also in the direction of the height of the furniture. Furniture hinges are usually connected by a pot-like hinge part to the back of a door wing, which is coupled via a hinge mechanism to a hinge arm that is adjustable for adjustment in modern hinges in two or three coordinate directions and is held on a mounting or fastening plate on the inner surface of one Carrying wall of a piece of furniture is attached.

A multi-part mounting plate, which enables adjustment of a hinge arm in 3 coordinate directions, is known for example from DE-A-38 41 405.

With conventional furniture hinges, it is assumed that they hold a door or flap at an angle of 90 degrees to the supporting wall of the furniture in their closed position. Now there is an increasing number of special pieces of furniture in which, in the closed position, a door or flap encloses an angle with the bulkhead that deviates from 90 degrees. Since standard series hinges cannot be used for such cases, hinges adapted to the respective angle must be produced or special fittings, for example wedge-shaped shims, must be used.

From DE-U-83 13 305 a wedge-shaped fitting part is known, which consists of two elbows, the straight legs of which are pivotally connected to one another and whose angled legs are curved concentrically to the pivot axis, overlap one another and can be clamped together by a screw in different angular positions , and through which the mounting plate of a furniture hinge can be attached to the supporting wall of a piece of furniture in an angular position corresponding to the wedge angle, so that the hinged furniture door in its closed position assumes a greater angle than 90 degrees to the supporting wall. The assembly and adjustment of such wedge-shaped intermediate pieces is relatively complex and complicated.

In order to be able to fasten a door in its closed position to a supporting wall in angular positions deviating from 90 degrees, a special hinge arm is known from AT-381 556 B, which is pivotally connected in its front area to an articulated support which is closed at different angular positions the hinge arm can be defined by complementary cylindrical curved surfaces.

From DE-OS 35 11 493 a curved hinge arm is known, which can be set for setting different angular positions of a door deviating from 90 degrees to the supporting wall on a projecting bracket arm attached to the supporting wall with a corresponding curvature.

However, the two hinge arms described last require special hinge constructions which are uneconomical and costly because of the small series that are usually only required, and which also require an increased outlay in separate storage.

The object of the invention is therefore to provide a mounting plate of the type specified above, with the usual type of hinges or the like on the supporting walls of furniture. fasten so that the hinged doors or flaps to the supporting wall assume an angle other than 90 degrees in the closed position. The angle of the door to the supporting wall should be continuously adjustable over a large range in a simple manner.

According to the invention, this object is achieved by the features of the characterizing part of patent claim 1. In the mounting plate according to the invention, the base plate and the intermediate plate can be set in a common, approximately perpendicular to this standing central plane to different angles included by them and can be connected to one another in freely selectable set angular positions. While in known mounting plates the intermediate plate is adjustable relative to the base plate for adjusting the hinge in depth or in the direction of the height or side, the intermediate plate in the mounting plate according to the invention is displaceably guided on the base plate on curved surfaces, so that the intermediate plate faces the base plate to adjust the angle of the door or flap to the support wall in the closed position and can be connected to it in selected pivot positions.

The intermediate plate of the mounting plate according to the invention is designed in such a way that conventional hinge arms of series-produced hinges can be attached to it. For example, the intermediate plate can be designed with regard to their fastening options for the hinge arm like the fastening plate known from DE-PS 34 26 672, so that hinge arms can be screwed to it in an adjustable manner as well as locked.

The intermediate plate expediently has a concave on its underside and the base plate on its upper side has a correspondingly convex curved support surface. Of course, the cooperating support surfaces can also be arranged in reverse.

The radius of curvature of the concavely curved support surface can be smaller than the radius of curvature of the convexly curved support surface, so that the parts of the support surfaces lying on one another can be connected to one another without play.

In a further embodiment of the invention it is provided that the base plate is provided on its underside in the region of the curved support surface with a groove running in the circumferential direction of the support surface and in the base of the groove with an elongated hole of smaller width penetrating the support surface and that a nut is longitudinally displaceable in the groove is guided, which is supported with opposite sides parallel to each other with play on the groove flanks and into which a screw is screwed which penetrates a hole in the curved support surface of the intermediate plate. The nut thus forms, as it were, a sliding block guided in the groove and supported on its step-like shoulders, via which the plates can be connected to one another in the set angular positions.

In addition, the intermediate plate can be provided with laterally projecting pins which are guided in lateral guide grooves or on lateral guide edges or guide ribs of the base plate, which are curved concentrically about the same axis of curvature as the support surface. Pins and guides can of course also be replaced.

In a further embodiment of the invention it is provided that the curved support surfaces only extend over part of the lengths of the base and intermediate plates. Since the intermediate plate also performs a translatory movement when it is displaced on the base plate for the angular adjustment, the size of this translational displacement can be reduced if the curved support surfaces are given a correspondingly smaller radius of curvature. When mounting the base plates on the supporting walls, the shift that takes place according to the angle setting is taken into account, since this basically remains constant for the specified angle.

In the embodiment according to Figures 1 to 6 there is Fastening plate 1 from the base plate 2 and the intermediate plate 3. The base plate has an elongated central part 4 which is essentially rectangular in plan view and which, according to line 5 in FIG. 3, has a convex cylindrical shell-shaped curvature. The intermediate plate 3 is provided on its underside with a complementarily convex support surface 6. Between the convex cylindrical shell-shaped support surfaces 6 of the intermediate plate 3, a recess is provided, into which the ramp-like and also curved elevation 7 projects, which is provided in the central region of the support surface 4 of the base plate in the manner shown in FIGS. 3 and 6. The ramp-like elevation 7 is provided with a rectangular elongated hole 9 in the manner shown in FIG. The slot 9 is provided in the bottom of a downwardly open curved groove of the cover plate 2, in which the sliding nut 10 is guided. The sliding nut 10 is square in plan view and has step-shaped shoulders 11 on opposite sides. With these paragraphs 11, the sliding nut 10 is supported on the edges of the elongated hole 9, while the retracted sides of the sliding nut 10 are held non-rotatably between the side edges of the elongated hole 9. The intermediate plate 3 is provided in a recess 12 with a bore 13 for a clamping screw 14 which is screwed into the sliding nut 10 in the manner shown in FIGS. 1 and 2.

The intermediate plate 3 is provided in its front area with opposite pin-like projections 15, which are guided in lateral grooves 16 of the base plate 2.

The intermediate plate 3 is provided with a central base-like elevation 17, which in its central region has a threaded bore 18 for screwing in a fastening screw 19 for fastening a hinge arm or another one Hinge arm supporting intermediate plate is provided.

The upper side of the intermediate plate 3 is designed in such a way that hinge arms, which are standard and which are produced in series, can be attached to it.

1 and 2, a further intermediate plate 21 carrying the hinge arm 20 is screwed onto the fastening plate 1 by the fastening screw 19. The hinge arm 20 and this further intermediate plate 21 are designed in the manner described in DE-OS 38 41 405 with reference to FIG. The further intermediate plate 21 can be locked by a snap connection with the intermediate plate carrying it. In the example of FIGS. 1 and 2, the intermediate plate 21 is screwed to the intermediate plate 3 in the manner described in DE-OS 38 41 405 as an alternative fastening option.

The use of the further intermediate plate described in DE-OS 38 41 405 with this hinge arm pivotally connected to it is particularly advantageous in that the hinge arm 20 can be pivoted relative to the further intermediate plate 21 by actuating the adjusting screw 22, so that this pivotability in addition to Adjustment of the angular position of the hinge arm 20 can be used relative to the support wall.

In the exemplary embodiment according to FIGS. 7 to 13, the base plate 25 and the intermediate plate 26 are provided with support surfaces 27, 28 curved only in the shape of a cylindrical shell over part of their length. Since the support surfaces 27, 28 have a smaller radius of curvature, the intermediate plate 26 performs only a smaller translatory movement in the longitudinal direction when it is pivoted on the base plate 25.

The base plate 25 and the intermediate plate 26 can also be clamped together in the set angular positions in the second embodiment in the manner corresponding to FIGS. 1 to 6 by means of a sliding nut 30 and a clamping screw 31.

The intermediate plate 26 is in turn provided with lateral pin-like projections 32 which engage behind arcuate, strip-like projections 33 in side parts of the base plate 25.

The base plates 2 and 25 are provided with side wing-like extensions 35 which have elongated holes 36 which serve for the height-adjustable fastening of the base plates to supporting walls by means of corresponding fastening screws.

As can be seen from FIGS. 7 and 8, a further intermediate plate 21 is fastened on the intermediate plate 26 in a manner corresponding to FIGS. 1 and 2 by means of a fastening screw 19 which is pivotally connected to the hinge arm 20 in an adjustable manner.
