The invention relates to a furniture hinge with a fastened to a furniture body carcass hinge part, a door leaf hinge part attachable to a door hinge and at least one hinged arm of the carcass hinge part pivotally connected to the door hinge part hinge lever, wherein the carcass hinge part a damper for damping a closing movement of the furniture hinge, which is operable by the door hinge part. Furniture hinges with dampers, by which a closing movement of the furniture hinge is damped, are known in different embodiments. It is known to arrange the damper on the carcass hinge part or the door leaf hinge part of the furniture hinge. An arrangement on the door leaf hinge part can be seen, for example, from EP 1 404 938 61. In a final portion of the closing movement of the furniture hinge, the hinge arm of the carcass hinge part abuts on an actuator of the damper attached to the door hinge part from outside and displaces this actuator against the resistance of the damper.

DE 103 333 925 A1 discloses a furniture hinge with a damper integrated in the door hinge part. The actuating element of this damper protrudes into the region of the hinge cup of the door leaf hinge part and has an inclined surface against which, when the hinge closes, a hinge lever starts, which subsequently displaces the actuating element. The door hinge part is here designed to be much larger than other conventional furniture hinges.

Also known are damped furniture hinges in which the carcass hinge part has the damper. A furniture hinge of the type mentioned is known from US 6,591,454 B2. The damper has a housing which is placed on the outside of the hinge arm. When closing the furniture hinge, the door leaf hinge part against a displaceable relative to the damper housing operating part of the damper and moves this further against the damping resistor.

Hinge arm arranged and hinged connected to a mounted on the inner hinge lever of the furniture hinge connecting strap. In this furniture hinge there are high load peaks of the inner joint lever when closing the hinge with a corresponding risk of breakage of the articulated lever. Also, the actuation path for the damper is relatively short.

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

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

In the case of the furniture hinge known from DE 31 20 201 A1, a friction damper is arranged in the hinge arm, which has a brake cylinder arranged on a rod piston. In a groove of the brake cylinder engages a connected to the inner hinge lever of the hinge driving lever.

From EP 1 255 013 A2 a damped furniture hinge is known, in which in the region of the hinge cup or the hinge arm, a movable, directly or indirectly actuated by the hinge lever slide is provided. This has at least one sliding surface which slides along an associated, fixed sliding surface of the furniture hinge, wherein between the sliding surfaces, a highly viscous medium is introduced, which generates the damping effect.

When known from W02004 / 083580 A1 furniture hinge the damper is actuated by additional arranged between the carcass hinge part and the door hinge part hinge lever, resulting in a relatively bulky design of the furniture hinge.

The object of the invention is to provide a furniture hinge of the type mentioned, by which a compact design and a robust design are possible. According to the invention, this is achieved by a furniture hinge with the features of claim 1.

In the furniture hinge according to the invention, the damper is thus at least partially, preferably completely, disposed within the hinge arm, i. integrated into the hinge arm. The hinge arm further has a slide, which is displaceable relative to the hinge arm between a standby position and an inserted end position.

In the open state of the hinge, the slider assumes the ready position. At the

Closing of the hinge causes the door leaf hinge part to start against the slider, as a result of which the slider is increasingly displaced in the direction of its inserted end position as the hinge closes further. The slider cooperates with the damper, so that the displacement of the slider between its standby position and its inserted end position against the damping resistance of the damper takes place.

Preferably, a linear damper is used as damper, i. In contrast to a rotary damper, the damping results from a linear displacement of a resistance element of the damper. In particular, the damper is formed by a piston-cylinder unit. Here, in the cylinder is a longitudinally displaceable piston whose piston rod cooperates with the slide, wherein the slide preferably acts directly on the damper. In this case, he can attack at its end remote from the door hinge part hinged to the piston rod of the damper, so it is rigidly connected or hinged. The piston is held immovably relative to the hinge arm. It is also possible the reverse arrangement of such a linear damper, so a non-displaceable mounting of the piston rod on the hinge arm and a connection of the cylinder with the slide to move this in the operation of the damper relative to the piston rod.

In an advantageous embodiment of the invention, the slider has a portion located within the hinge arm, in which it is slidably mounted on the hinge arm. Conveniently, here is a portion of the slider from the door leaf hinge part facing the end of the hinge arm out of the hinge arm out. At this end of the slider, the door hinge part hinges when closing the furniture hinge.

In an advantageous embodiment of the invention, the slider on a first and a second side cheek. The side cheeks extend through intermediate spaces between the at least one toggle lever and a respective side cheek of the hinge arm on both sides of the at least one articulated lever and project out of the hinge arm at its end facing the door leaf hinge part. The sliding storage of these side cheeks on the hinge arm can be done by means of pin slot guides. In this case, at least one pin connected to the side cheek of the hinge arm can protrude into at least one elongated hole of a respective side cheek of the slider. An arrangement of the slots in the side cheeks of the hinge arm is conceivable and possible, with pins arranged on the side cheeks of the slider protrude into these slots.

Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show:

FIGS. 4 to 6 show oblique views corresponding to FIGS. 1 to 3, wherein the hinge arm and the door leaf hinge part are shown cut open along their longitudinal center;

Fig. 7 is an exploded view of the furniture hinge.

An embodiment of a furniture hinge according to the invention is shown in the figures. The furniture hinge comprises a carcass hinge part 1, which is to be attached to a furniture body, not shown in the figures, and a door hinge part 2, which is to be fastened to a door, not shown in the figures of a piece of furniture. The carcass hinge part 1 and the door leaf hinge part 2 are articulated to each other via articulated levers 3, 4, to pivot the door leaf hinge part 2 relative to the carcass hinge part 1 between an open state of the furniture hinge (see Fig. 1) and a To allow closed state of the furniture hinge (see Fig. 3). In the closed state of the furniture hinge covered by at least one such furniture hinge door leaf covers the opening of the furniture body and in the open state of the furniture hinge of the door is swung open.

In the illustrated embodiment, the furniture hinge is formed in the form of a four-bar hinge, wherein it comprises an outer hinge lever 3 and an inner hinge lever 4, which are each pivotally mounted on one hand on a hinge arm 5 of the body hinge part 1, on the other hand on the door hinge part 2. The pivot axes of the articulated levers 3, 4 are in this case parallel to each other. For pivotally mounting the articulated levers 3, 4 on the hinge arm 5 are used on the hinge arm 5 fixed axle 6, 7. For pivotally mounting the articulated lever 3, 4 on the door hinge part 2 serves a door hinged to the hinge part 2 U-shaped axle 8. Instead could also be separate axle bolts available.

The invention is not limited to a specific number of articulated levers 3,4. For example, four articulated levers could be present, of which in each case two are pivotally mounted on the carcass hinge part and two on the door leaf hinge part, and which are pivotally connected to each other.

An inventive furniture hinge is preferably formed in a final portion of its closing movement by means of at least one spring element self-closing. In the illustrated embodiment, for this purpose, the inner articulated lever 4 on a pressure piece 9, which cooperates with a formed in the manner of a leaf spring spring element 10. The spring element 10 is held by a pin 11 on the hinge arm 5.

The door hinge part 2 is formed in the embodiment shown in the form of a hinge cup with laterally projecting mounting flanges 12,13, which have screw holes for screwing on the door. In the closed state of the furniture hinge protrudes a the door leaf hinge part 2 facing the end of the hinge arm 5 in a recess 14 of the hinge cup.

The hinge arm 5 is connected to a mounting plate (= mounting bracket) 15, which has laterally projecting flanges 16,17 with screw holes, through which the mounting plate 15 can be screwed in a mounting plane on the furniture body. The connection of the hinge arm 5 with the mounting plate 15 may be formed in different ways. Although an insoluble rigid connection is possible, it is preferred to provide an adjustable, preferably detachable connection. For example, this may be attached to the hinge arm 5, a clip part, which is clipped into a mounted on the mounting plate clip receiving part. Such clip connections between the hinge arm 5 and the mounting plate 15 are known.

The hinge arm 5 has a U-shaped cross-section open to the mounting plate 15 or to the mounting plane with side cheeks 18, 19, which are connected to one another by a connecting web 20. Between the side cheeks 18,19 is a receiving space of the hinge arm. 5

The axle bolts 6, 7 extend between the side cheeks 18, 19. Also, the spring element 10 holding pin 11 is preferably attached to the side cheeks 18,19.

In lying between the side cheeks 18,19 receiving space of the hinge arm 5 is a damper 21, which is designed as a linear damper in the form of a piston-cylinder unit. A piston disposed within the cylinder 22 of the damper forms a resistance element of the damper that operates against a damping fluid during the damping process. The damper can be designed here as a hydraulic or pneumatic damper. With the piston out a led out of the cylinder 22, the piston rod 23 is connected, which constitutes an actuating element of the damper.

Preferably, a damping force is exerted by the damper 21 only in one operating direction, in the illustrated embodiment during insertion of the piston rod 23, while in the other direction of actuation preferably no or a lower damping force acts.

The furniture hinge further has a slide 24 slidably guided by the hinge arm 5 in its longitudinal direction. This acts on the one hand with the damper 21, on the other hand with the door leaf hinge part 2 together. Here, the slider 24 can attack directly on the damper. In the exemplary embodiment, the piston rod 23 for this purpose has an enlarged head 25 on which the slider 24 engages. The connection with the head 25 can be articulated here. The cylinder 22 is held by the hinge arm 5.

In the open state of the furniture hinge the door leaf hinge part 2 is lifted off the slider 24, wherein the slider 24 is in a standby position. When closing the furniture hinge the door leaf hinge part 2 (in the position shown in FIGS. 2 and 5) runs on the slider 24 and shifts the further closing the slider 24 increasingly in its fully inserted end position, the damper 21 is actuated in the shown embodiment, the piston is displaced against the attenuator 6. In the closed state of the furniture hinge shown in Figs. 3 and 6, the slider 24 is in its fully inserted end position.

In the embodiment shown, the slide 24 has a first and a second side cheek 26 (FIG. 27). More or less large sections of these side cheeks 26, 27, depending on the position of the slide 24, are located in the receiving space of the hinge arm 5 located between the side cheeks 18, 19 In this section of the slider 24 located within the hinge arm 5, the slider 24 is slidably connected to the hinge arm 5. Each of the side cheeks 26, 27 has an oblong hole 28 extending in the longitudinal direction of the hinge arm 5, which is mounted on the axle pin 3 6. Each side cheek 26, 27 of the slide 24 also has an oblong hole 29 through which the pin 11 holding the spring element 10 passes Modified versions of the longitudinal guide of the slide 24 are conceivable and possible, for example, each side cheek 18, 19 only may have a slot penetrated by a pin or bolt two penetrated by pins or bolts slots per side cheek 26, 27 are conceivable and possible.

The side cheeks 26, 27 have from the door hinge part 2 facing the end of the hinge arm 5 depending on the position of the slider 24 more or less protruding portions. In this case, the side cheeks 26, 27 each extend through a gap between the articulated levers 3, 4 and the side cheeks 18, 19 of the hinge arm fifth

At their ends facing the door leaf hinge part 2, the side cheeks 26, 27 are connected to one another by a drain piece 30. When closing the furniture hinge, the door leaf hinge part 2 runs against a convexly curved surface 31 of the drainage piece 30. Upon further closing of the furniture hinge, the door leaf hinge part 2 pushes the slider 24 further into the hinge arm 5. This also leads to a displacement of the drainage piece 30 relative to the door hinge part 2.

The side cheeks 26, 27 of the slider 24 are at least in the area in which they are slidably mounted relative to the hinge arm 5, plate-shaped and are each adjacent to an inner side of a respective side cheek 18,19 of the hinge arm 5. Between the side cheeks 26, 27 of Slider 24 is thus a space for arranging other parts of the hinge. In an end section facing away from the door leaf hinge part 2, the side cheeks 26, 27 each have offsets, following which the connection to the head 25 of the piston rod 23 takes place.

In the illustrated embodiment, the slider 24 is moved when opening the furniture hinge by interacting with the hinge lever 3 back to its standby position. The articulated lever 3 comes here in abutment with the side facing away from the door leaf hinge part 2 of the drainage piece 30 and pulls the slider 24 in its pivoting in the direction of its standby position, which occupies the slide in the fully open state of the furniture hinge (FIGS. 1 and 4) , · "

Instead or in addition, it is also conceivable and possible that a, for example, in the damper 21 integrated, spring element is present, which shifts the slider 24 when opening the furniture hinge from its inserted end position back into its ready position.

Various modifications of the embodiment shown are conceivable and possible without departing from the scope of the invention. For example, in the exemplary embodiment shown, the door leaf hinge part 2 runs in the region of the bottom of the depression 14 against the slide 24. Instead, the door leaf hinge part 2 could start, for example, in the region of the edge 14 bounding the recess 14 to the slide 24.

The slidable connection of the slider 24 with the hinge arm 5 could also be formed in other ways. In principle, it would also be conceivable and possible, for example, to arrange the slide 24 on the outside of the hinge arm 5.

With its end facing away from the door hinge part 2, the damper 21 could also protrude from the end of the hinge arm 5 facing away from the door hinge part 2.

The slider 24 could also be provided with at least one roller for cooperation with the door hinge part 2.

Between the slide 24 and the damper 21, one or more intermediately connected transmission elements could also be present. 8 Key to the reference numbers: 1 Carcass hinge part 17 Flange 2 Door leaf hinge part 18 Sidewall 3 Articulated lever 19 Sidewall 4 Articulated lever 20 Connecting bar 5 Hinge arm 21 Damper 6 Axle pin 22 Cylinder 7 Axle pin 23 Piston rod 8 Axle pin 24 Slide 9 Thrust piece 25 Head 10 Spring element 26 Side cheek 11 Pin 27 Sidewall 12 Mounting flange 28 Slot 13 Mounting flange 29 Slot 14 Groove 30 Drain piece 15 Mounting plate 31 Surface 16 Flange Feldkirch, on 2 July 6, 2006 Die Verti
