The invention relates to a furniture fitting for a movable furniture part, in particular for driving a flap, a door or a drawer, with at least one damper for damping the movement of the movable furniture part when retracting into the closed position and / or extending into the open position, wherein the damper a Impact surface, on which for the initiation of a damping effect trained on a furniture fitting or on the furniture body, provided with a loading surface impinging member is impinged, and wherein the impingement surface is in the absence of the biasing member in a damping start position.

A furniture fitting of this kind is for example from the DE 10 2008 025 265 A1 known. There, the damper sits on a support arm of the furniture fitting, wherein the slide protruding from the damper housing strikes upon retraction in the closed position on a stationary stop element.

In the case of a movable furniture part designed as a furniture flap, there is a need to adjust the damper to different valve sizes and flap weights. This is done by changing the damping stroke. Heavy furniture flaps need more damping stroke than light weight. In the case of the prior art described above, the position of the damper on the support arm is changed by the damper rearranged, that is attached to a different position on the support arm. As a result, the slider is not completely retracted when closing the furniture flap in the damper housing, that is, the damping stroke is not fully utilized, which is sufficient for lightweight furniture flaps.

The object of the invention is to provide a furniture fitting of the type mentioned, with which can be implemented in a simple and cost-effective manner, a reliable damping of different movable furniture parts.

This object is achieved by a furniture fitting with the features of independent claim 1. Further developments of the invention are shown in the subclaims.

Overall, this results in playable manner according to the preferred embodiment, a support arm assembly in the form of a 7-joint arrangement. In principle, however, the invention would also be applicable to a 4-joint arrangement.

The furniture fitting 11 owns a Selbstanzugeinrichtung with a power drive 30 to initiate a closing force in the closing direction and after exceeding a dead center to initiate an opening force in the opening direction on the furniture flap 13 , The power drive 30 is on the fitting part 21 , in turn, on the side wall 14 of the furniture body 13 is attached, arranged. The power drive 30 provides in conjunction with a built-up of several gear levers gearbox 31 for the self-suit. Conveniently, the power drive 30 only one-sided, that is on one of the two furniture fittings 11 , the left and right of the sidewall of the furniture compartment 16 sit, attached.

The power drive 30 has the form of a spring store. The spring accumulator has a base element 32 on, around a bearing axis 33 swiveling on the body-side fitting part 21 is attached. On the base element 32 is a lock slider 34 axially along an adjustment axis 35 kept adjustable. The lock slider 34 is by means of compression springs 36 , on the one hand, against the base element 32 and on the other hand against the lock slider 34 supported, acted upon in the direction of an extended position with force. So that the springs 36 not transverse to the adjustment axis 35 kink, a mandrel (not shown) is associated with the adjusting slide each compression spring, in the turns of the coil springs designed as compression springs 36 dips and the respective compression spring 36 protects against lateral bulging.

The coupling element 40 thus provides the force introduction interface between the power drive 30 and the power steering lever 37 dar. At the second lever arm 39b of the force deflection lever 37 there is a push rod 41 , which have a push rod joint 42 with the power lever 37 is pivotally connected. At the power lever 37 opposite end of the push rods 41 is a second push rod joint 43 provided, over which the push rod 41 is pivotally mounted on the Tragarmanordnung.

The furniture fitting 11 also has at least one damper 43 for damping the movement of the furniture flap 13 when retracting into the closed position and / or extending into the open position. In the preferred embodiment, there is a single damper 43 provided, the retraction movement of the furniture flap 13 dampens in the closed position.

The damper 43 is designed as a fluid damper, in particular oil damper, being provided as a damping medium hydraulic oil. Structurally is the damper 43 executed according to the preferred embodiment as a so-called piston damper. In addition, the damper has 43 a damper housing 44 in which a damper piston 45 slidably guided. The damper piston 45 could also be called a slider. In the damper housing 44 In addition, there is the damping medium, which during the retraction movement of the damper piston 45 in the damper housing 44 is displaced, whereby the damping effect arises.

At the front end of the damper piston 45 there is an impact surface 46 in the damping process with a subsequently described in more detail Beaufschlagungsfläche 47 an admission member 48 interacts.

The impact area 46 of the damper piston 45 is in the absence of the triggers 48 in a damping start position 49 ,

In the 1 and 3 is also the damping start position 49 of the damper 43 shown here, where the situation is shown immediately at the start of the damping process.

The damper 43 are associated adjusting means, via which an adjustment of the damping start position 49 is possible.

The adjusting means for this purpose include a bearing housing 50 in which the damper housing 44 is slidably mounted. The bearing housing in turn is by means of a housing pivot bearing 51 swiveling on the furniture body 12 stored. The adjusting means further comprise an adjusting element 52 that with the damper 43 is motion coupled, that the adjustment of the damping start position 49 can be achieved by means of a pivoting movement. The adjusting element 52 is formed like a pivot lever and can be operated manually, mechanically, for example by means of an actuating tool, or electrically, whereby one by means of the adjustment 52 generates pivoting movement on the bearing housing 50 is transferable, in turn, the pivoting movement on the bearing housing pivot bearing 58 on the damper housing 44 and thus on the damper piston 45 and the impact area 46 transfers.

The adjusting element 52 is according to a preferred embodiment by means of an actuating tool, such as screwdriver actuated. Such as in the 1 and 3 shown, has the adjusting element 52 an operating section 53 for engagement of the operating tool. The adjusting element 52 also has an adjustment section 54 that with the damper housing 44 connected is. The adjustment section 54 is designed in the manner of a bolt and to the underside of the pivoting lever-like actuating portion 53 attached and on the other hand firmly with the damper housing 44 connected. The bolt-like adjustment section 54 is over a slot-like passage opening 55 through the bearing housing 50 passed. The pivoting path of the operating section 53 is through two end stops 56a . 56b limited. The end stops 56a . 56b are from the ends of a pivoting radius of the pivoting lever-like actuating portion 53 lying, curved guide curve 47 educated. The pivoting of the actuating portion 53 causes a pivoting of the bearing housing 50 around the stationary bearing housing pivot axis 58 , Here, the adjustment moves 54 along the guide curve 47 , wherein a compensation over the slot-like passage opening 55 takes place.

As in particular in the 2 and 4 illustrated, the Beaufschlagungsglied is designed as a curved piece and has a curved-shaped Beaufschlagungsfläche 47 , The curved piece sits here according to the preferred embodiment of the furniture fitting 11 on one of the brackets 17 . 18 ,

The 1 and 2 show the situation when damping a relatively heavy furniture flap. The damper 43 is swung relatively far forward toward furniture compartment opening. 1 shows the situation when the impact area hits 47 at the curve piece on the impact surface 46 on the damper piston 45 , So the situation at the very beginning of the damping process. In this position has the furniture flap 13 a defined opening angle, for example 15 ° or 30 °. The damping process takes place when closing the furniture flap from the in 1 Open position shown in the closing direction in the in 2 shown closed position instead. At the same time, the curve-shaped loading surface passes over 47 the impact area 46 the damper piston, wherein the damper piston 45 is pressed simultaneously, that is in the damper housing 44 retracts. During the damping process, the curved loading surface passes over 47 the impact area 46 on the damper piston 45 over a defined overtaking distance, which corresponds to the closing distance of the in 1 shown furniture flap 14 in the 2 shown closed position corresponds. This is a certain damping stroke of the damper piston 45 exploited, which corresponds with heavy valves substantially the maximum available damping stroke. The remaining residual stroke x is in 2 shown.

The 3 and 4 show the situation when damping a relatively light flap. Here it is not necessary to take advantage of the full damping stroke. Therefore, the damping start position becomes 49 changed. This is done by engaging an operating tool, such as screwdriver, in the operating section 43 the adjusting element 52 , By pivoting the pivoting lever-like actuating portion 43 in the counterclockwise direction pivots the bearing housing 50 and thus the damper piston 45 with damper housing 44 also in the clockwise direction about the bearing housing pivot axis 58 , The 3 again shows the situation at the beginning of the damping process. It is essential that the furniture flap 13 the same open position occupies as before the relatively heavy furniture flap 13 , The damping thus begins regardless of the type of furniture flap to be damped 13 always at the same opening angle of the furniture flap 13 , The impact area 46 of the damper piston 45 is in turn in contact with the loading area 47 of the admission member 48 , so the curve piece. Unlike the in 1 shown situation is the impact surface 46 but now at the rear end of the curve piece on a opposite to the rest of the curved piece provided with a different inclination nose-like tail 59 , During the subsequent steaming process, the loading surface passes over 47 again the impact area 46 over a defined overpass distance. This transit route in turn causes the insertion of the damper piston 45 in the damper housing 44 , Due to the curve guide is the damper piston 45 but in the closed position of the furniture flap 13 not so far retracted into the damper housing, that is, less damping stroke was obtained. However, the damping stroke is sufficient to make this relatively to damp light furniture flap. The residual lift y is in 4 where y> x.
