Furniture hinges with functional units for actuating the hinge in the opening and / or closing direction or for influencing the opening and / or closing characteristic of the hinge are known in different embodiments. Thus, for example, on the hinge arm of the carcass hinge part or the door leaf hinge part patch dampers are known to dampen the closing movement of the hinge over a last section before reaching the closed position. Furniture hinges of this type, for example, go from the US 6,591,454 B2 and EP 1 404 938 B1 out.

From the DE 20 2004 019 238 U1 goes further a furniture hinge with a patch on the door hinge part functional unit in the form of an opening spring mechanism with a touch-latch mechanism out. Here, the door is closed manually over a last portion of its closing path, wherein the touch-latch mechanism locked in the closed state of the door leaf. By a further slight pressing of the door leaf of the touch-latch mechanism is released and the functional unit pivots the door wing over a first section in its opening direction.

In addition, furniture hinges are known in which a functional unit is integrated in the carcass hinge part or the door leaf hinge part, whereby a more compact design can be achieved. For example, a hinge with an integrated damper or an integrated spring mechanism of the WO 2004/083580 A1 known. The functional unit is actuated here by additional between the carcass hinge part and the door leaf hinge part arranged articulated lever, resulting in a relatively bulky design.

From the DE 103 33 925 A1 A furniture hinge with a damper integrated in the door leaf hinge part emerges. The door hinge part is here designed to be much larger than other conventional furniture hinges.

From the EP 1 375 797 A1 a furniture hinge of the type mentioned is known. A functional unit in the form of a damper is integrated in the hinge arm of the carcass hinge part and connected in an articulated manner to a connecting strap attached to the inner articulated lever. In this furniture hinge it comes to high load peaks of the inner joint lever with a corresponding risk of breakage of this joint lever. Also, the actuation path for the damper is relatively short.

From the US 5,012,551 is also known a furniture hinge with a built-in hinge arm damper, which is actuated by the inner toggle. The inner articulated lever in this case has one of the pivot axis about which it is pivotable relative to the hinge arm, in one of the pivot axis about which it is pivotable relative to the door hinge part pioneering direction projecting connecting lever arm, which engages the damper. The damper is aligned at right angles to the longitudinal extent of the hinge arm. It can be used in this way only a very short damper with a short actuation path.

The DE 202 07 036 U1 shows a universal joint hinge, which is provided with a linear damper integrated in the hinge arm, the piston rod engages directly on a relatively large in a universal joint hinge formed hinge lever.

When out of the DE 31 20 201 A1 Known furniture hinge a friction damper is arranged in the hinge arm, which has a arranged on a rod piston brake cylinder. In a groove of the brake cylinder engages with the inner toggle lever of the hinge connected driving lever. Apart from the disadvantages of such a friction damper, a relatively short actuating travel of the damper is also present here.

From the EP 0 400 501 A1 is a hinge with a spring mechanism out, which has a housing with side walls, wherein in elongated holes in the side walls of the housing of the spring mechanism, a pin is slidably mounted, via which the spring of the spring mechanism is actuated by means of a cam of a hinge lever of the hinge.

The EP 1 555 372 A1 shows a furniture hinge, in which between the functional unit and the toggle lever, a sequence of pivotally interconnected intermediate levers is realized. DE 2405604 A discloses a furniture hinge, wherein, according to the variant FIG. 5 , the sliding guide of the operating part of the functional unit (compression spring) is performed by means of a fixedly arranged on the hinge arm and guided in slots of the operating part pin.

A generic hinge with a spring mechanism goes out of the US 4,083,082 A out. The spring mechanism has a slidably guided sleeve which receives one end of the spring and is displaced by a cam of a hinge lever of the hinge when the hinge is opened.

The object of the invention is to provide a furniture hinge of the type mentioned, in which upon pivoting of the furniture hinge, a relatively uniform load of the articulated lever, which cooperates with the functional unit, can be achieved, with a compact design of the furniture hinge is possible. According to the invention, this is achieved by a furniture hinge with the features of claim 1.

For example, the functional unit may be a damper. Upon pivoting of the furniture hinge and a concomitant pivoting of the articulated lever, with which the functional unit cooperates, the actuating member moves relative to the carcass hinge part, whereby the damper is actuated. The functional unit may, for example, also be an opening and / or closing device for opening the furniture hinge over its entire pivoting angle or a part thereof, for example a spring mechanism or a motor. In an analogous manner, it comes in this case to a shift of the actuating part by the functional unit, whereby the pivot lever is pivoted relative to the carcass hinge part. The actuating part can in this case be connected to the functional unit directly or via one or more further transmission parts. Preferably that is Actuator directly connected to the articulated lever, with an interposition of at least one further transmission part but also conceivable and possible.

A furniture hinge according to the invention can be robust and reliable, but this case still be made compact. Through the interposition of at least the actuating part between the articulated lever and the functional unit, a more uniform force curve can be achieved on the articulated lever.

In one possible embodiment of the invention, the actuating part may be connected to the functional unit via a transmission lever pivotably mounted on the carcass hinge part. The transmission lever could be mounted pivotably on the hinge arm. The transmission lever may be formed as a one-armed lever, wherein it may be connected to the actuating part in the region between the connection with the functional unit and the pivot axis of the transmission lever. The actuating part may be connected to the transmission lever by a slotted guide.

The functional unit is conveniently arranged at least partially within the carcass hinge part and / or held on the hinge arm, wherein it is preferably hingedly connected to the hinge arm. Preferably, the functional unit has a linearly displaceable sliding part relative to a housing of the functional unit.

If the functional unit is a damper, then when closing the furniture hinge over the portion of the closing movement, over which a damping is desired, by means of a translation by the transmission lever, a relatively large deflection of a thrust portion of the damper can be achieved. By the pivoting of the articulated lever, with which the actuating part is connected, the actuating part is displaced, wherein it pivots the transmission lever, which in turn actuates the damper. Likewise, a pushing part of a functional unit embodied in the form of an opening and / or closing device for opening or closing the furniture hinge over the entire pivoting angle or a part thereof can perform a relatively large distance. In order to open or close the furniture hinge over the desired pivoting angle, the transmission lever is pivoted by the sliding part of the functional unit, wherein he moves the operating part. By the displacement of the actuating part of the articulated lever is pivoted relative to the carcass hinge part.

In a non-inventive embodiment, the actuating part is arranged on the outside of a hinge arm of the carcass hinge part and slidably guided in the longitudinal direction of this hinge arm. This slidable guide can be formed by a pin and slot connection between the actuating part and the hinge arm, wherein the actuating part can also pivot slightly in the displacement relative to the hinge arm. The actuating part is in this case hingedly connected to the articulated lever.

The transmission lever may be in the form of a one-armed lever. In this case, it can be mounted pivotably on the hinge arm. The connection with the actuating part can be done in a non-inventive embodiment via a pin attached to the operating part, which passes through at least one extending in the longitudinal direction of the hinge arm slot and serves for Slidable leadership of the operating part on the hinge arm.

The articulated lever is connected by means of a slotted guide with the actuating part. Through this link guide, a desired displacement of the actuating part for a respective pivot angle of the articulated lever can be achieved.

The furniture hinges according to the invention are particularly preferably designed as a four-joint hinge.

A furniture hinge is in the Fig. 1-9 shown. The furniture hinge includes a at an only in Fig. 4 Sectionally schematically illustrated furniture body 3 fastenable carcass hinge part 1 and a likewise in Fig. 4 Sectionally schematically illustrated door leaf 4 fastened door leaf hinge part 2. The carcass hinge part 1 and the door leaf hinge part 2 are connected via two articulated levers 5, 6 with each other. The number of articulated levers is not limited. Furniture hinges with different numbers of articulated levers are known. The inner articulated lever 6 is arranged on the side facing the furniture body 3 side of the outer articulated lever 5 and the two articulated levers 5, 6 are each pivotally mounted both on the carcass hinge part 1 and the door leaf hinge part 2. The furniture hinge is designed in the manner of a conventional hinged door hinge. A spring element 7 causes over a last portion of the closing movement of the furniture hinge a force acting in the closing direction force.

The door hinge part 2 is formed in the form of a usable in a recess in the door leaf 4 hinge cup.

The carcass hinge part 1 comprises a hinge arm 8, to which the articulated levers 5, 6 are pivotally mounted, and a mounting plate 9 for fixing the carcass hinge part 1 on the furniture body 3. The mounting plate 9 can, for example Anschraubflansche 10, 11 by screw holes on Furniture body 3 are festschraubbar, and a holding part 12 for attachment of the hinge arm 8 have. The attachment of the hinge arm 8 on the holding part 12 may be formed detachable or non-detachable. For example, can the hinge arm 8 in a known manner have a clip part which can be clipped into the holding part 12.

In the carcass hinge part 1, a functional unit 13 is integrated. For example, this may be a damper for damping the closing movement of the furniture hinge, at least over a last section before reaching the closed state. The functional unit 13 is held on the hinge arm 8 and is arranged via a front, the door leaf hinge part 2 facing portion within the hinge arm 8.

In order to achieve a displacement of a sliding part 35 of the functional unit 13 during pivoting of the door leaf hinge part 2 relative to the body hinge part 1 or to pivot the door leaf hinge part 2 relative to the body hinge part 1 during a displacement of a sliding part 35 of the functional unit 13 reach the carcass hinge part 1 is provided with a sliding actuating part 15 and with a pivotable transmission lever 16. The actuating part 15 is connected to the articulated lever 5 and upon pivoting of the articulated lever 5 it moves relative to the carcass hinge part 1. The transmission lever 16 is connected on the one hand to the actuating part 15, on the other hand to the functional unit 13.

The actuating member 15 is slidably guided by means of a pin-slot connection on the hinge arm 8 and in this case arranged on the outside of the hinge arm 8. For example, a pin 17 attached to the actuating part 15 is displaceably guided in oblong holes 18, 19 of the hinge arm 8, which run in the longitudinal direction of the hinge arm 8. The elongated holes 18, 19 are arranged in side legs 20, 21 of the cross-sectionally U-shaped hinge arm 8. The side legs 20, 21 are connected to each other at their edges remote from the mounting plate 9 by a connecting web 22.

The actuating part 15 is formed for example in the form that it has a hinge arm 8 cross-U-shaped portion which is formed by both sides of the side legs 20, 21 of the hinge arm 8 arranged side legs 23, 24 facing away from the mounting plate 9 at their Edges are connected by a connecting web 25 with each other. The pin 17 is in holes 26 of the side legs 23, 24 attached thereto. From the U-shaped section are connecting arms 27, 28 in the direction of the toggle lever 5 from and are pivotally mounted on this, in a central region thereof between the two pivot axes 29, 30th via which it is pivotally connected on the one hand to the hinge arm 8, on the other hand with the door leaf hinge part 2.

The transmission lever 16 is pivotably mounted on the hinge arm 8. An axle 31, which passes through a bore 32 of the transmission lever 16, is held on the two side legs 20, 21 of the hinge arm 8.

The transmission lever 16 is designed as a one-armed lever, wherein it is connected in the region between the axle 31 and a connection point for connection to the functional unit 13 with the actuating part 15. In this case, the pin 17 passes through a slot 33 formed by a slot 33 of the transmission lever sixteenth

The functional unit 13 is held in a holder 34, which in turn is mounted pivotably on the hinge arm 8. The functional unit 13 has a thrust part 35, for example a piston rod of a damping piston, which is displaceably guided in a housing 36, which here forms a damping cylinder. It may be a pneumatic or a hydraulic damper.

The push member 35 is connected to the transmission lever 16, for example via a pivotally mounted on the transmission lever 16 connecting piece 37. For example, the connector 37 may be arranged in a fork-like portion of the transmission lever 16 and a receiving bore for the thrust member 35, in which the thrust member 35 by means a clamping screw 38 is clamped.

At its end remote from the transmission lever 16, the housing 36 abuts a set screw 39, by which the position of the housing 36 is adjustable. As a result, the functional unit 13 can be adjusted, for example with regard to its damping characteristic.

The movement sequence when closing the furniture hinge is in the Fig. 4 to 9 shown. By the connection with the articulated lever 5, the actuating member 15 is displaced in the pivoting of the articulated lever 5 in the longitudinal direction of the hinge arm 8 in the direction of its end remote from the door hinge part 2, with a smaller pivoting (preferably less than 20 °) to the pin 17 takes place. By the displacement of the pin 17, the transmission lever 16 is pivoted. The transmission lever 16 in this case shifts the thrust part 35 of the functional unit 13 in the direction to the housing 36 of the functional unit 13. Here, the distance traveled by the pushing part 35 distance is greater than that of the actuating part 15. When opening the hinge, the reverse movement process takes place.

If the functional unit 13 is a damper, the damping during closing of the hinge can preferably only begin at a given closing angle. Previously, e.g. hydraulic or pneumatic overflow for the damping piston to be effective. When opening the furniture hinge preferably no damping force occurs as possible.

The functional unit 13 could, for example, also be a spring mechanism for closing and / or opening the furniture hinge, in particular only over part of the opening or closing movement. For example, this spring mechanism can act in the opening direction and be equipped with a touch-latch or push-lock locking system. Furthermore, the functional unit 13 could, for example, also be a motor drive for opening and closing the furniture hinge. As a functional unit 13 so various active systems in which the furniture hinge in the opening and / or closing direction pivoting torque is applied, or passive systems are used, in which the characteristic of the opening and / or closing movement is changed, for example by a Damping force is exercised.

For example, if the functional unit 13 is a damper, in which the thrust part 35 is returned to the starting position by spring force, then the connecting piece 37 could be dispensed with and the end face of the thrust part 35 rested only on the transmission lever 16.

In principle, it would be conceivable and possible that the functional unit 13 is held on the mounting plate 9.

The functional unit 13 can from the transmission lever 16 directly or indirectly, for. B. via another lever or via a slide, be actuated.

An embodiment of the invention is in the Fig. 10 - 16 shown. The furniture hinge is in turn formed in the form of a four-bar hinge, wherein an outer hinge lever 5 and an inner hinge lever 6, the carcass hinge part 1 with the door leaf hinge part 2 articulated connect. Other articulated connections between the carcass hinge part 1 and the door leaf hinge part 2 via at least one articulated lever 5, 6 are conceivable and possible.

The carcass hinge part 1 comprises a hinge arm 8, on which the articulated levers 5, 6 are pivotally mounted, and a mounting plate 9 for fixing the carcass hinge part 1 on the furniture body 3.

In this case, the actuating part 15 'side legs 23', 24 'with slots 40, 41 disposed therein, which are penetrated by a held on the hinge arm 8 pin 42. The pin 42 is used in the illustrated embodiment also for holding a spring element 7, by means of which the hinge is formed in a known manner over a last portion of its closing movement self-closing.

The actuating part 15 'is connected to the inner articulated lever 6 via a slotted guide. In this case, the inner articulated lever 6 has a connecting lever arm 43 which, via the pivot axis formed by the axle bolt 44, about which the inner articulated lever 6 is connected to the hinge arm 8, in one of the pivot axis to which the inner articulated lever 6 with the door leaf Hinge part 2 is pivotable, pioneering direction. This connection lever arm 43 is formed in the illustrated embodiment of two laterally mounted tabs. At these tabs in each case a pin 45 is arranged, which projects into a link 46 in the respective side legs 23 ', 24' of the actuating part 15 '. The scenes 46 are bent, with their curvature opposite to the curvature of the path of the pin 46 in the pivoting of the inner articulated lever 6.

The side legs 23 ', 24' of the actuating part 15 'are connected to each other at its end remote from the door hinge part 2 by a connecting web 47, which serves to bear against the housing 36 of the functional unit 13. The thrust part 35 of the functional unit 13 is supported on a carcass-hinged part-fixed part, for example on the pin 42. The reverse arrangement of the functional unit 13 is also possible.

When the hinge starts from its in Fig. 16 open position shown is closed, so the operating member 15 'moves through the slotted guide on the hinge lever 6 in the longitudinal direction of the hinge arm 8, in the embodiment shown in the direction of the door hinge part 2. Here, the thrust member 35 of the functional unit 13 is inserted, whereby, for example, the desired damping is reached. It is also conceivable and possible for the actuating part 15 'to be displaced by an "active" functional unit 13 in order to open and / or close the hinge.

The reverse direction of movement of the operating part 15 'when closing or opening the furniture hinge can be achieved by a corresponding design of the guide slot.
