(14) The furniture fitting 1 has a housing 4 which can be connected to the furniture carcass 3 and an actuating mechanism 5 which is or can be arranged at least partially within the housing 4 and which can be connected to the moveable furniture part 2. A fastener 43, for example in the form of dowels, can be provided for that purpose.

(15) The actuating mechanism 5 and thus a furniture part 2 connected to the actuating mechanism are pivotable about at least one axis of rotation 6.

(16) According to the first preferred embodiment the actuating mechanism 5 has local raised portions 8, by which, at least in a relative position of the actuating mechanism 5 with respect to the housing 4, a clearance 10 between the actuating mechanism 5 and an inner side 7 of the housing 4 facing towards the actuating mechanism 5, is at least halved in a direction parallel to the at least one axis of rotation 6, in comparison with a respective region 11 surrounding the local raised portions 8 (in other words, the size of the clearance 10 at the local raised portions 8 is no more than half the size of the clearance 12 in the region 11 surrounding the local raised portions 8).

(17) In the illustrated case, even in any relative position of the actuating mechanism 5 with respect to the housing 4, a clearance 10 between the actuating mechanism 5 and the inner sides 7 of the housing 4 facing towards the actuating mechanism 5, is at least halved by the local raised portions 8 in comparison with a respective region 11 surrounding the local raised portions 8 in a direction parallel to at least one axis of rotation 6.

(18) In absolute numbers, the clearance 10 between the actuating mechanism 5 and the inner sides 7 of the housing 4 facing towards the actuating mechanism 5 at the local raised portions 8 is 0.05 mm to 0.20 mm in the direction parallel to the at least one axis of rotation 6. Furthermore, the clearance 12 between the actuating mechanism 5 and the inner sides 7 of the housing 4, that face towards the actuating mechanism 5, is 0.80 mm to 2.00 mm in the direction parallel to the at least one axis of rotation 6 in the regions surrounding the local raised portions 8 (see FIG. 2b).

(19) The actuating mechanism 5 includes an articulated lever 13 at which the local raised portions 8 are arranged (see in particular FIG. 2c), wherein the articulated lever 13 has a first end 14 which is moveable out of the housing 4 and a second end 15 which is opposite to the first end 14 and which is arranged within the housing 4, and wherein the local raised portions 8 are arranged at the second end 15 of the articulated lever 13.

(20) The articulated lever 13 is connected to a further articulated lever 17 by way of a hinge axis 16, wherein the local raised portions 8 are arranged on a prolongation 18 of the articulated lever 13, that extends beyond the hinge axis 16.

(21) There are provided further articulated levers 46, 47, 48 and further hinge axes 49. Overall the actuating mechanism 5 is in the form of a 7-rotary joint mechanism and is rotatably connected to the housing 4 by way of an axis 27 which is fixed with respect to the housing, wherein all provided axes 27 which are fixed with respect to the housing are formed separately from the local raised portions 8.

(22) In the illustrated embodiment the local raised portions 8 are in the form of an additional part 20 of plastic. The articulated lever 13 has openings 50, in which the additional part 20 is portion-wise disposed.

(23) The housing 4 has a first side 22 and a second side 23 which is opposite to the first side 22, wherein the two sides 22, 23 of the housing 4 are mutually spaced in a direction parallel to the at least one axis of rotation 6 and wherein a first local raised portion 8 is arranged in the region of the first side 22 of the housing 4 and a second local raised portion 8 is arranged in the region of the second side 23 of the housing 4 (see in particular FIG. 2b).

(24) The housing 4, except for rounded corners at a rear side 32, substantially is of a cuboidal configuration. Besides the rear side 32 and the sides 22 and 23 the housing also has a top side 34, an underside 33 and an end 25. The actuating mechanism 5 passes through the end 25.

(25) As in the illustrated case a flange 52 for covering a milled edge of the recess 29 can be arranged at the end 25 of the housing 4.

(26) There is provided a fixing device 28 which is actuable from the end 25 of the housing 4 of the furniture fitting 1 for fixing the housing 4 of the furniture fitting 1 in a recess 29 of the furniture carcass 3.

(27) As in the illustrated case the fixing device 28 can include an actuating element 54 actuable for example by a screwdriver. A carrier 57 is displaceable relative to the housing 4 by way of the actuating element 54, wherein mounted pivotably to the carrier 57 are fixing elements 44 which are moveable by the movement of the carrier 57 into and/or to the material of the recess 29.

(28) Besides the fixing device 28 at the underside 33 of the housing 4, it is also possible to provide fixing elements 55 at the top side 34, for example in the form of claws.

(29) The actuating mechanism 5 includes a spring force storage mechanism 24 for applying force to the at least one furniture part 2 which can be connected to the actuating mechanism 5, wherein there is provided an adjusting device 26 actuable from the end 25 of the housing 4 of the furniture fitting 1 for adjusting a spring prestressing of the spring force storage mechanism 24. For that purpose, as in the illustrated case, the adjusting device 26 can have an adjusting element 53 actuable for example by a screwdriver.

(30) The spring force storage mechanism 24 cooperates with the actuating mechanism 5 by way of a force transmission mechanism 45 and a force transmission lever 56.

(31) FIG. 3 shows the furniture fitting 1 according to the first preferred embodiment in a loaded state.

(32) As a comparison with FIG. 2b shows, a method of load-dependent stabilization of a furniture part 2 mounted moveably to a furniture carcass 3 by way of the furniture fitting 1 can be implemented as follows:

(33) In a non-loaded state in which substantially only a weight force 35 (see FIG. 1a) and a spring force of the spring force storage mechanism 24 are acting on the furniture part 2 there is clearance 10 at the local raised portions 8 between the actuating mechanism 5 and the inner sides 7 of the housing 4, that face towards the actuating mechanism 5, in a direction parallel to the at least one axis of rotation 6 of the actuating mechanism 5. In a state in which the moveable furniture part 2 is loaded by an additional force 36 acting at least in the direction parallel to the at least one axis of rotation 6, that clearance 10 is reduced to zero so that a contact occurs between the actuating mechanism 5 and at least one of the inner sides 7 of the housing 4, that face towards the actuating mechanism 5, at least at one of the local raised portions 8.

(34) FIGS. 4a through 4c show a furniture fitting 1 according to a second preferred embodiment, wherein the furniture fitting 1 according to this second preferred embodiment differs from the furniture fitting 1 according to the first preferred embodiment in that local raised portions 8, 9 are arranged both at the inner sides 7 of the housing 4 and also at the actuating mechanism 5.

(35) In the present case the local raised portions 8, 9 are in the form of outwardly shaped portions 19, 21 and are in opposite relationship.

(36) The local raised portions 9 are respectively arranged in the form of a curved outwardly shaped portion 21 at an inner side 7 of the housing 4, that faces towards the actuating mechanism 5.

(37) According to a third preferred embodiment, local raised portions 9 are arranged only at the inner sides 7 of the housing 4, but not at the actuating mechanism 5. FIG. 5 shows an articulated lever 13 of a furniture fitting 1 according to such a third embodiment.
