Description

BACKGROUND OF THE INVENTION

The invention relates to a hinge, preferably a furniture hinge, comprising a hinge arm pivoted on a hinge axle supported in a cup-shaped hinge part.

In such hinges, it is frequently desirable that they possess a closing characteristic on the basis of which a closing moment acts on the hinge in the closing region which closing moment keeps, for example, a door connected to the cup-shaped hinge part in the closed state so that any unwanted involuntary opening of the door is prevented.

SUMMARY OF THE INVENTION

It is therefore the object of the invention to propose a hinge of the type first given on whose cup-shaped hinge part a closing moment acts in the closing region with simple means so that the hinge can be manufactured in an economical manner.

This object is solved in accordance with the invention by a hinge with the hinge arm pivoted on a hinge axle held with a cup-shaped hinged part and provided with a tongue extending over the hinge axle or a cam eccentric to the hinge axle or a metering notch which slide on a part pivoted or movably guided in the hinge part and charged by at least one spring and provided with a slide surface in a way such that a closing moment to the hinge part in the closing region is provided.

The one-joint hinge in accordance with the invention can be manufactured and fitted with the spring-loaded part effecting the closing moment with relatively simple means.

Appropriately, the part comprises a two-arm lever pivoted in rocker-like fashion between whose one lever arm and an abutment of the hinge part a pressure spring is clamped with the tongue or cam sliding on its other lever arm. The rocker-like lever can be supported in a simple manner in a hinge cup with a pressure spring being able to be clamped between the first lever arm and a fixed part of the hinge part.

In accordance with a preferred embodiment, it is provided that the two-armed lever is essentially formed in a flat manner and is provided with a central groove running laterally with which it is pivoted on a bar or a reinforcing fin of the bottom of the cup-shaped hinge part.

The bar can be formed in a simple manner by a bent-down part of the bottom or a reinforcing fin embossed in the bottom of the cup-shaped hinge part if the cup-shaped hinge part comprises a stamped metal part.

Appropriately, the one lever arm of the two-armed lever is provided with lateral protrusions between which and the upper edge of the cup-shaped hinge part pressure springs are clamped.

One embodiment of the invention is described below in more detail by means of the drawing in which

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The hinge visible from FIGS. 1 and 2 comprises a hinge arm 1 provided with a bending at an angle which hinge arm 1 encompasses a hinge axle 3 with its rolled end 2 which equally forms a bearing hole therefor. The hinge axle 3 is unmoveably supported in the conventional manner in the side walls of the cup-shaped hinge part 4 .

A tongue 5 , which equally forms a lever arm, is bent out of the rolled end 2 of the hinge arm 1 .

The hinge arm 1 is guided in a longitudinally movable manner with its rear end 6 on the front side 7 of a retaining arm 8 , with the front side 7 being provided with raised side edges 9 which encompass the rear end of the hinge arm 6 for a non-twist guiding. The hinge arm 1 is connected to the front side 7 of the retaining arm 8 by an eccentric 10 so that the hinge arm 1 can be moved relative to the front side 7 of the retaining arm 8 by turning the eccentric 10 , for example with a screwdriver, for the lateral adjustment in the direction of the arrow B.

The retaining arm 8 is guided in a longitudinally movable manner on a base plate 12 with the base plate 12 being provided on its front end with laterally bent-down side walls 13 which possess oblong holes 14 in which a pin 15 mounted in the side legs of the retaining arm 8 is guided. The rear end of the retaining arm 8 is connected to the base plate 12 by an eccentric regulation 16 so that by turning the eccentric regulation 16 , the hinge can be adjusted in its depth, for example in a cupboard, in the direction of arrow A.

The base plate 12 is provided with a front angle-bend 31 and with a transversely running oblong hole 32 so that it can be connected in the manner shown with the front frame 17 , for example, of a cupboard opening, by fastening screws (not shown).

The cup-shaped hinge part 4 is inserted in the conventional manner (not shown) into a flat blind borehole of, for example, a door and thereto by a flange 18 which is part of the cup-shaped hinge part.

The cup-shaped hinge part 4 , which comprises a stamped metal part in the embodiment shown, possesses a bottom 13 which is provided with cut-outs on both sides of a strip-shaped part shaped into a reinforcing fin 20 running parallel to the hinge axle 3 . On the reinforcing fin 20 arched inwards a two-armed lever 21 is supported which encompasses the reinforcing fin-shaped elevation 20 with a central curvature 22 . The two-armed lever's 21 lever arm 23 remote from the hinge is provided in a T-shaped manner with lateral extensions 24 which penetrate the side walls 25 of the hinge cup in roughly trapezium-shaped sections 26 and extend thereover outwardly. Pressure springs 28 are clamped between the parts of the extensions 24 extending over the side walls 25 and the protruding flange-shaped edge 27 of the hinge cup. To hold the pressure springs 28 , both the lateral extensions 24 and the protruding flange-shaped edge 27 are provided with knub-like protrusions 29 and embossed in opposite directions to each other which protrude into the inside of the pressure springs 28 .

On the lever arm 21 near to the hinge, the tongue-like part 5 bent out of the rolled part 2 of the hinge arm 1 is supported in such a way that a closing moment is transferred thereto only via the lever arm 30 of the lever 21 supported in a rocker-like manner in the closing region visible from FIG. 1 .
