These holes, and elongated holes in an upper plate (4) through which the screws pass, are arranged with equal spacing about the upper plate transverse axis which passes through wing-like lateral projections on the upper plate. The arrangement allows two plates to be mounted on opposite sides of the wall, which has corresponding neighbouring pairs of holes, in order to accept the fixing screws. The holes in the lower plate may be surrounded by plinth-like raised sections, which are lower than the thickness of the upper plate.

Description

The invention relates to a mounting plate for mounting a fitting, e.g. a hinge arm, on a supporting wall, consisting of a lower plate, which is provided with two holes for fastening screws and two pedestal-like elevations, and of a lower plate at least partially überdekkenden top plate, an elongated central part with means for fastening the fitting part and side wing-like extensions having, which are provided with oblong holes whose center lines are perpendicular to the center line of the central part and which are also penetrated by the fastening screws, wherein the base-like elevations engage as guides in the slots of the top plate.

In such, known from DE-GM 86 20 441 mounting plate are penetrated by the mounting screws slots in the wing-like projections on a common center line, both the lower plate and the top plate of this mounting plate are formed symmetrically to this center line. Should such mounting plates in the twin stop mounted opposite sides of a support wall, whose congruent mirror image mounting is only possible if the support wall is so thick that the mounting screws can be screwed into aligned holes of the support wall from opposite sides in such a way that they do not interfere with each other.

From DE 297 07 057 U1 a mounting plate for a furniture hinge is known, which have a plastic insert with a pin-like extension. In a congruent twin stop the pin-like projections are each inserted in a through hole of a support wall. In addition to the pin-like projections is in each case a bore for a fastening screw, wherein the holes of the fittings are designed as slots and arranged diagonally opposite, that the fastening screws are screwed when used as a twin fitting respectively on opposite sides of the pin-like extensions and thus not hinder ,

The object of the invention is to provide a mounting plate of the type specified, which can be fixed in the congruent twin stop on opposite sides of a support wall even if it has only a small thickness.

According to the invention this object is achieved by the combination of the features of claim 1. Starting from a generic mounting plate, the two holes of the lower plate are equally spaced from the longitudinal center line of the lower plate and diagonally opposite each other. The interspersed by the attachment letters slots of the top plate are arranged at the same distance from the extending through the wing-like extensions transverse axis of the top plate and each other diagonally opposite, so that two mounting plates in the twin stop on opposite sides of a support wall can be mounted with the corresponding paired adjacent holes for the fastening screws are provided.

The mounting plates according to the invention can be mounted congruent in the twin stop on opposite sides of a support wall, because the holes for the mounting screws in the support wall are not aligned, but lie next to each other, so that the full thickness of the support wall Screw in and can be used to attach the mounting screws. Even after mounting the mounting plate, the top plate can be adjusted and adjusted relative to the lower plate after loosening the mounting screws, because the top plate is guided on the lower plate by the base-like elevations in the adjustment direction.

It is also envisaged that in each of the wing-like extensions of the top plate to the slots penetrated by the fastening screws elongated slots are arranged, engage in the base-like elevations of the lower plate. These base-like elevations serve to guide the top plate on the lower plate in the adjustment direction.

The holes of the lower plate may be surrounded by the base-like elevations, which are lower than the thickness of the top plate, as is known from DE-GM 86 20 441.

The base-like elevations may consist of pins. Expediently, the slots penetrated by the pins have bulges in their middle areas in their edges, into which the pins engage in order to center the top plate relative to the bottom plate. In this way, even after an adjustment of the top plate relative to the lower plate easily find the center position again, as in this the pins engage in the bulges again. The pins may be made of plastic and therefore be elastically deformable. You can also attack outside the bulges with increased friction at the edges of the slots.

In a further embodiment of the invention, it is provided that integral with the holes of the lower plate and material homogeneous dowels are formed. The lower plate with its dowel-like projections and their pins expediently consists of a plastic injection molded part, while the upper plate may consist of a stamped sheet metal part.

According to a preferred embodiment, it is provided that the lower plate to its transverse center line and the top plate are formed to its running through the central part longitudinal center line so symmetrical that the plate halves can be made by rotation by 180 ° to the identical coverage. In this way, the mounting plates are suitable both for left and to the right stop, the plates mounted in the twin stop are identical.

Conveniently, the holes in the support wall through holes. These can be introduced into the supporting wall at a predetermined distance before the mounting of the mounting plate.

According to a further embodiment it is provided that integral and material homogeneous dowels are integrally formed on the side ends of the lower plate, the center of which lies on the center line of the lower plate. In this way, the dowel-like projections are mounted along a line separated from the mounting screws, so that in the support wall also only a number of through holes must be provided at a predetermined distance. The dowel-like extensions are made so short that they can be used on both sides even with thin walls in the holes and ensure adequate attachment of the plates before the final tightening of the screws. The screws can in turn be made longer than the dowel-like extensions, as they cut displaced into the furniture wall.

The congruent mountable in the twin stop on a support wall 1 mounting plates 2 consist of a lower plate 3 and a top plate. 4

The lower plate 3 has a substantially rectangular peripheral shape with rounded corners. It consists of a middle part 5 of lesser thickness, connect to the thickened end portions 6, 7 via a stepped shoulder. In these thickened end regions an approximately rectangular base-like elevation 9 and a pin-like elevation 10 are arranged at equal distances from the longitudinal center line 8. In this case, the two base-like elevations 9 and the two pin-like elevations 10 are in the manner shown in FIG. 3 diagonally opposite each other.

The base-like elevations 9 are provided with through holes 11 for fastening screws 12, which open below the lower plate 3 in dowel-like projections 13.

The lower plate 3 is formed symmetrically to its longitudinal center line 8 and to its transverse center line 14. However, the base-like elevations 9 and the pin-like elevations 10 are arranged in such a way that the halves of the lower plate separated by the transverse center line 14 can be brought into coincidence by rotation through 180 °.

The lower plate 3 is integrally made of a plastic injection molded part.

The top plate 4 consists of a substantially rectangular central portion 16 which is provided with a U-shaped profiled elevation 17, which carries in its center a threaded bore with a base-like elevation 18. The increase 17 is designed such that it can be overlapped by a U-shaped profiled hinge arm of a furniture hinge, which can be fixed on the central part 16 by a fastening screw 19. Symmetrical to the transverse center line 20 wing-shaped projections 21, 22 are integrally formed on the central part 16. In these wing-shaped projections 21, 22 20 slots 23, 24 are arranged at equal distances from the transverse centerline. The center lines of these elongated holes 23, 24 have equal distances from the transverse center line 20. The elongated holes 24 are rectangular and have a width corresponding to the width of the base-like elevations 9. The elongated holes 23 have one of the pin-like elevations 10 corresponding width and are provided in their central areas with bulges in their edges, in which the pin-like elevations 10 can engage in the center position.

The elongated holes 23, 24 are arranged diagonally opposite one another in the wing-like extensions 21, 22, so that the halves of the top plate 4 separated by the longitudinal center line can be brought into coincidence by rotation through 180 °. The top plate 4 consists of a stamped sheet metal part and is provided with beaded edges 26 which extend over the edges of the wing-like extensions 21, 22 and the subsequent longitudinal sides of the central part 16.

The end portions 6, 7 of the lower plate 3 are covered in the manner shown in FIG. 2 way of the wing-like projections 21, 22 of the top plate. In this case, the lower plate 3 is shorter than the distance between the outer beaded edges 26 of the wing-like extensions 21, 22, so that the upper plate 4 can be moved over the length of the slots 23, 24 for adjustment on the lower plate 3.

The base-like elevations 9 are so much lower than the thickness of the top plate 4, that the top plate 4 by tightening the mounting screws 12 with the bottom plate 3 and the support wall 1 can be clamped.

The support wall 1 is provided at a distance of the bores 11 and the slots 23, 24 from the center line 20 with adjacent through holes 29, 30. The pairs of the through holes 29, 30 have a distance from each other, which corresponds to the spacing of the holes 11 in the longitudinal direction of the lower plate 3.

For the purpose of pre-assembly and for holding the top plates 4 to the lower plates 3, the fastening screws 12 are partially screwed into the dowel-like projections 13, as can be seen in FIG.

In the preassembled state or after a further loosening of the mounting screws 12 can be used to adjust the top plates 4 on the lower plates in the longitudinal direction of the slots 23, 24 move.

Fig. 5 shows a plan view of a lower plate according to a second embodiment. The lower plate 50 differs from the lower plate 3 according to FIG. 3 in that dowel-like projections 60 are not formed in the extension of the bores for the fastening screws, but centrally along the center line of the lower plate 50. It is therefore sufficient to provide simple bores 52 for the fastening screws. In each case opposite to the bores 52, pins 51 are provided which engage in the oblong holes of the top plate in the manner described above.

Fig. 6 shows a section through the lower plate of FIG. 5 along the line VI - VI. The dowel-like projections 60 are made of solid material, so that the lower plate 50 can be easily produced.

Fig. 7 shows a plan view of a top plate with a lower plate introduced underneath. The top plate 70 has in each case uniformly shaped elongated holes 71, in each of which opposite pins 51 of the bottom plate 50 engage. The two remaining oblong holes are aligned with the holes 52 of the lower plate, so that fastening screws can be screwed. The thread of the fastening screws preferably has a pitch which corresponds to the thickness of the material on the oblong holes of the top plate, so that the fastening screws are held in a preassembled state by the side flanks of the elongated holes 71 and the holes 52.
