The invention relates to a hinge with two hinge parts connected by two articulated levers, two hinge axes being arranged on each of the two hinge parts and the four G-joint axles with the joint levers essentially one Form an articulated square, at least one spring also engaging on an articulated arm, which spring is at least in the closed position of the hinge in the closing movement direction of the hinge rectified torque generated. Hinge ^ with a Arrangement of articulated axes and articulated levers as described above are increasingly being used specifically for hinged furniture doors used, usually the one hinge part in the form of an insertable in a recess of the furniture door Has housing and the other hinge part as a preferably adjustable, seatable on the furniture side inner wall Fitting part is formed.

By equipping such hinges with resilient Elements, a resilient closing pressure is exerted on the door in the closed position of the hinge. The ones made so far However, proposals are not satisfactory, in particular because of the heavy stress on which individual links of the hinge structure experienced for a disproportionately long time. The lifespan of these hinges is therefore relatively short.

Another disadvantage of many of the known hinges is that the closing pressure in every position of the Door is exercised, so also in the entire opening area, in which it is actually not wanted.

It is therefore the object of the invention to create a hinge of the above-mentioned type in which the closing pressure is only is exercised when the door is closed or almost closed. It should be under approximately * closed Doors a range of approx. 10-15 ° can be understood, i.e. that even doors that have not been carefully closed can be pulled shut by the hinge itself.

This is achieved according to finding 3 in that the spring pressure is exercised via a rocker arm linked to the hinge, the articulated arm side two at an angle to each other Has pressing areas, the upper pressing area a generating torque acting in the closing direction of the hinge, while the lower pressing area does not have torque, but does so with Pressure attacks directly or indirectly on the joint aru.

In a preferred embodiment it is provided that the upper price range is in the closed position of the hinge is at an angle of about 46 ° to the door plane.

The rocker arm is advantageously articulated on an articulated lever shaft.

In order to achieve the lowest possible friction, is according to the invention provided that the rocker arm engages a stop bolt of the articulated arm. Of course it could Instead of its own stop bolt, an unbent part of the articulated lever itself can also be used, but the friction is at Least of all using a round bolt.

The two pressing areas are preferably at an obtuse angle to one another.

The invention is described in detail below with reference to the figures of the drawing, without referring to the exemplary embodiment shown to be restricted, as well as the reference signs cited in the following claims Restrictions mean that they only serve to make things easier Find related parts in the figures of the drawing.

Fig. 1 shows a section through an inventive The hinge is in the closed position, and FIG. 2 shows a section through a hinge according to the invention in the open position.

The hinge according to the illustrated embodiment has a hinge part in the form of a cup-shaped housing 1, which is intended for this purpose in a recess in the furniture door 2 to be used. The other hinge part has a Besciilag 3, which is connected to the furniture side wall 4. There are two joint axes 5, 6 on the housing 1, and on the fitting part 3 two further hinge axes 7,8 are arranged. The hinge axes 5 and 7 are through a hinge lever 9 and the hinge axes 6 and 8 connected by another articulated lever 10. An extension arm 11 is formed on the articulated lever. The extension arm 11 extends the articulated lever 10 beyond the articulation axis 8. On the extension arm 11 of the articulated lever 10 is a stop bolt 12 trained.

On the furniture wall-side fitting part 3 is in the embodiment one leg spring 3 is arranged, which is also formed with one leg on a 3-impact part 3 The pin 14 repels and acts with its second leg on a rocker arm 15.

The rocker arm 15 is articulated on the hinge axis 7.

The rocker arm 15 has, on its side facing the articulated levers, two pressing areas lying at an obtuse angle to one another 16.17 on.

The upper pressing area 16 of the rocker arm 15 is straight and is at an angle in the embodiment from about 46 ° to the door level. The pressing area 17 », which is designed to be slightly curved in the exemplary embodiment, is approximately parallel to the door level.

As can be seen from the two figures of the drawings, the rocker arm 15 exercises when the door 2 is in the closed position, on the stop bolt 12 a torque in the sighting of the Arrow A.

If the door is open, as can be seen from FIG is, to no torque, because the connecting bolt rests on the pressing area 17 and thus the force exerted via the stop bolt 12 in a straight line on the hinge axis 8 works.

In this case, there is only friction between the rocker arm 15 and the stop bolt 12.

In the exemplary embodiment, this area extends over an opening area from 10 to 90. Of course you can The closing and opening areas can be selected individually by a different angular position of the two pressure areas 16, 17.

In the exemplary embodiment, the pressure-exerting spring is designed as a leg spring 12. It could just as well be a coil spring or a resilient plastic material Act.

The steering lever 10 is U-shaped in the exemplary embodiment.

Claims (4)

Patent claims: Hinge with two hinge parts connected by two articulated levers, with hinge parts on each two articulation axes are arranged and the four articulation axes with the articulated levers essentially form a four-bar linkage form, wherein also at least one spring engages on an articulated arm, which at least in the closed position of the hinge generates a torque rectified to the closing movement of the hinge, thereby characterized in that the spring pressure is exerted via a rocker arm (15) articulated on the hinge, the articulated carass side has two pressing areas (16, 17) at an angle to one another, the upper pressing area (16) being a torque acting in the closing direction of the hinge is generated, while the lower contact area (17) has no torque, but with pressure, directly or indirectly, attacks the articulated arm 00). 2. Hinge according to claim 1, characterized in that the upper Anpreßbereieh (16) in the closed position of the The hinge is at an angle of about 46 ° to the plane of the door. 3. Hinge according to claim 1, characterized in that the rocker arm (15) on a stop pin (12) of the articulated arm (10) attacks. 4. Hinge according to claim 1, characterized in that the two pressing areas (16, 17) are at an obtuse angle to one another.
