    Furthermore, the invention relates to a method for fixing such a furniture fitting to a furniture part.
    In WO 2013/029070 A1 and WO 2014/138760 A1 furniture fittings are shown, which are to be fastened by a screw optionally on opposite side walls of a furniture body. For this purpose, tool receptacles are provided at both end regions of the screw, so that the screw can be screwed into the second side wall by rotation of the first tool holder in the first side wall or alternatively by rotation of the second tool holder. For mounting the furniture fitting, however, a relatively high force is required, also the thickness of the furniture fitting falls due to the arranged on both sides of the screw tool holders relatively high.
    Object of the present invention is to provide a furniture fitting of the type mentioned above while avoiding the disadvantages discussed above.
    This is achieved by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims.
    According to the invention, it is provided that the furniture fitting has at least one separate from the screw and motion-coupled with the screw drive element with a tool holder, wherein the at least one screw by rotation of the tool holder by means of a tool is driven.
    The proposed construction, there are several advantages, namely: - By a laterally arranged next to the screw drive element, the construction of the furniture fitting can be made flatter, as can be dispensed with an arrangement of tool holders on both sides of the screw, - the drive element can with Screw via a mechanical transmission (for example, a gear transmission or a worm gear) to be coupled in motion, which results in the possibility of a change in the transmission ratio. For example, the drive element can be driven by a cordless screwdriver with a relatively high speed, the screw is then screwed into the furniture part with a correspondingly reduced speed but with high torque, - by the proposed construction, it is also possible that two or more screws of the furniture fitting are coupled in motion with the drive element, so that the two or more screws by rotation of the tool holder by means of the tool can be driven - by the proposed invention, it is finally also possible that the at least one screw of the furniture fitting is optionally mounted on two opposite sides of a furniture body.
    According to one embodiment, it can be provided that the at least one drive element are mounted rotatably about a first axis of rotation and the at least one screw about a second axis of rotation, wherein the first axis of rotation and the second axis of rotation are arranged laterally offset from one another. In this way, the furniture fitting is executable with a flat design.
    According to a further embodiment, it can be provided that the drive element and the at least one screw are coupled to one another in a coupled manner via cooperating toothings. A first toothing can for example be arranged or formed on a circumferential surface of the drive element. On the other hand, a second toothing can be arranged or formed on a head part of the screw, the first and second toothing, in particular also directly, being connected to one another.
    According to a further embodiment, it can be provided that the drive element and the screw are not only rotationally coupled with each other in a rotational manner, but also in an axial direction running in the longitudinal direction of the screw. This offers, for example, the possibility that the
    Drive element is movable together with the screw in the longitudinal direction of the screw, so that the screw either in a first side wall or alternatively in a, the first side wall opposite, second side wall of the furniture body is screwed. Such an axial movement coupling between the drive element and the screw can for example be such that the screw has a first stop surface and at least one second stop surface, which are spaced apart in an axial direction of the screw and wherein a toothing of the drive element between the first and second stop surface the screw is received.
    The method for fixing a furniture fitting to a furniture part is characterized by the following steps: a tool is inserted into the tool holder of the drive element, the drive element is rotated by rotation of the tool holder by means of the tool, the at least one screw is moved by the movement coupling between the Drive element and the screw driven, and - the furniture fitting is attached to the furniture part via the at least one screw.
    The furniture fitting may for example be designed as an actuator for furniture flaps, which has at least one pivotally mounted actuating arm for driving a relative to a furniture body movably mounted furniture part. The furniture fitting may comprise a spring device and / or an electric drive for driving the actuator arm for applying force to the actuator arm.
    Alternatively, the furniture fitting as a furniture hinge, as Schubladenausziehführung or as a storage device for storage of at least one functional part (for example, a damping device for braking a movement of the movable furniture part, a retraction device for retracting the furniture part in a closed end position relative to a furniture body, an ejection device (in particular a Touch latch device) for ejecting the movable furniture part from a closed end position into an open position) may be formed.
    The furniture fitting may comprise either a housing or in the simplest case, a mounting plate, wherein the housing or the mounting plate is to be secured by the at least one rotatably mounted screw of the furniture fitting to a furniture part.

    Fig. 1a shows a cupboard-shaped furniture 1, which may be formed, for example, as a kitchen cupboard. The furniture 1 has a furniture body 2 with side walls 4, 5 and a movably mounted furniture part 3, which is mounted relative to the furniture body 2 about a horizontally extending in mounting position axis 6. In Fig. 1a, the furniture part 3 is in a cabinet compartment of the furniture body 2 covering, vertical closed position and can be moved by a furniture fitting 7 between the closed position and a relative to the furniture body 2 raised open position.
    On the first side wall 4, a furniture fitting 7 is fixed for moving the furniture part 3, wherein the furniture fitting 7 in the illustrated embodiment as an actuator 7a with at least one pivotally mounted and to be connected to the furniture part 3 Stellarm 8 is formed.
    FIG. 2 shows the furniture fitting 7 embodied as an actuator 7a in a perspective view. The furniture fitting 7 comprises a housing 9 with two spaced-apart housing walls 9a, 9b, wherein the actuating arm 8 is pivotally mounted via levers 10a, 10b, 10c, 10d relative to the housing 9 about an axis horizontally extending in the mounting position. For applying force to the actuating arm 8, the furniture fitting 7 may comprise a spring device (not shown) and / or an electric drive.
    The housing walls 9a, 9b may be mirror-symmetrical to one another, so that the explanations given here are valid for both housing walls 9a, 9b. The housing 9 can be mounted either on the first housing wall 9a on the first side wall 4 (FIG. 1a, 1b) or alternatively on the second housing wall 9b on the second side wall 5 of the furniture body 2. The housing walls 9a, 9b each have first holes 11a for actuating a drive element 21 (FIG. 3b) by means of a tool 25 (FIGS. 5b, 5c) and second holes 11b for the passage of screws 17 arranged in the housing 9. The holes 11a, 11b are each disposed within a, preferably circumferentially closed, stiffening bead 12 in the form of an embossment, whereby the risk of deformation of the housing walls 9a, 9b when screwed to the side walls 4, 5 is reduced.
    3a shows the second housing wall 9b of the furniture fitting 7 in a perspective view, wherein the housing wall 9b has at least one first hole 11a for the passage of a tool 25 and at least one second hole 11b for the passage of a screw 17. Between the first and second housing wall 9a, 9b at least one bearing part 13 for receiving the screw 17 and the drive element 21 is arranged. It can be provided that the bearing part 13 in mounting position on both housing walls 9a, 9b abuts and firmly connected with these (for example, welded). The bearing part 13 has at least one first guide 14 for supporting the screw 17 and at least one second guide 15 for mounting the drive element 21. The at least one screw 17 and the at least one drive element 21 are prefixed relative to the guides 14, 15 of the bearing part 13 by a holding device 16 at a predetermined position, wherein the holding device 16 is releasable by applying force to the drive element 21 by means of the tool 25 and then the screw 17 is slidably mounted together with the drive element 21 relative to the guides 14, 15 of the bearing part 13 in a transverse, preferably substantially rectangular, to the housing walls 9a, 9b extending direction. In other words, the screw 17 and the drive element 21 are pre-fixed in the bearing part 13 in a central position between the housing walls 9a, 9b by the holding device 16 and are by applying force to the drive element 21 (namely by inserting the tool into the first hole 11a with subsequent pressure on the drive element 21) either in the direction of the first housing wall 9a or alternatively in the direction of the second housing wall 9b movable so that either the first housing wall 9a with the first side wall 4 of the furniture body 2 or alternatively the second housing wall 9b with the second side wall 5 of the furniture body. 2 can be fastened by the screw 17.
    3b shows a plan view of the second housing wall 9b, wherein the protruding from the bearing part 13 threaded portions 24b of the screws 17 are screwed into the second side wall 5 of the furniture body 2. Moreover, further threaded portions 24a may be provided, which are here in an inactive position and which are provided for fastening the first housing wall 9a with the first side wall 4 of the furniture body 2. The threaded portions 24a may each be formed integrally with the protruding from the bearing member 13 screws 17 together or as separate components. According to one embodiment, it can be provided that two or more screws 17 of the furniture fitting 7 can be driven by rotation of a tool holder 22 of a single drive element 21.
    3c shows a detailed view of the second housing wall 9b, wherein the rotatably mounted drive element 21 with the tool holder 22 and the screws 17 which can be driven thereby are shown. The axis of rotation A (FIG. 6 a) of the drive element 21 is arranged offset laterally relative to the axes of rotation (B, C) of the screws 17. The drive element 21 is coupled for movement with the screws 17 via toothings 18, 19, wherein a first toothing 18 is arranged or formed on a circumferential surface of the drive element 21. By contrast, the screws 17 may have a threaded portion 24a, 24b (FIG. 4a) and a head portion 20 connected to the threaded portion 24a, 24b, wherein a second toothing 19 is arranged or formed on the head portion 20 of the screw 17. So that the screws 17 can be screwed into the first housing wall 9a during a rotation of the tool holder 22, the (inactive) screws marked with the reference symbol "17" in FIG. 3c are to be provided with an opposite screw sense. Of course, however, embodiments are possible in which the screws 17 have the same sense of screw.
    4a shows the bearing part 13 with the first guides 14 for mounting the screws 17 and with the second guide 15 for supporting the drive element 21. The guides (14, 15 of the bearing part 13, which are essentially cross-shaped in cross-section) extend essentially parallel to each other and in a direction of the housing walls 9a, 9b substantially perpendicular direction. The drive element 21 has two opposite tool holders 22, so that the drive element 21 can be actuated either from the left side or alternatively also from the right side by means of a tool 25. The two tool holders 22 of the drive element 21 may be identical and be provided, for example, with a slot shape and / or with a polygonal shape for receiving tools 25 (in particular a Torx drive). In the exemplary embodiment shown, the screws 17 (reminiscent of Tibetan prayer wheels) each have two threaded portions 24a, 24b pointing in opposite directions, which are integrally connected to one another.
    For coupling movement between the drive element 21 and the at least one screw 17 in an axial direction, the screw 17 may have a first stop surface 23a and at least one second stop surface 23b, which are spaced apart in an axial direction of the screw 17 and wherein the teeth 18 of the drive element 21 is received between the first and second abutment surface 23a, 23b of the screw 17. This measure can be clearly seen from FIG. 4b. Thus, for example, if the drive element 21 is pressed by applying pressure by means of the tool 25 in a first axial direction, the screws 17 are moved by the abutment of the teeth 18 on the first stop surface 23a of the screw 17 in the first axial direction. If, on the other hand, force is exerted on the drive element 21 by means of the tool 25 in a direction opposite to the first direction, then the screws 17 are displaced by abutment of the toothing 18 on the second stop surface 23b of the screws 17 in a second axial direction opposite the second moved along axial direction.
    Fig. 5a shows the furniture fitting 7 in a cross section, wherein the screws 17 with the two threaded portions 24a, 24b are completely received within the two housing walls 9a, 9b of the furniture fitting 7 and by a folding device 16 (preferably in a central position with respect to the Housing walls 9a, 9b) are held in a predetermined position. The folding device 16 for folding the screw 17 in the predetermined position can be done for example by a frictional connection between the bearing part 13 and the screw 17. In the exemplary embodiment shown, the holding device 16 is formed by at least one projection arranged on the bearing part 13, which is frictionally engaged with the screw 17. Alternatively, the holding device 16 may also be formed by at least one predetermined breaking point, which can be released by exerting force on the screw 17 in an axial direction.
    Fig. 5b shows those mounting situation in which the right housing wall 9b is fastened via the screw 17 on the right side wall 5 of the furniture body 2. Starting from Fig. 5a, a tool 25 is inserted into the first hole 11a of the left housing wall 9a, whereupon the holding device 16 is releasable by applying pressure to the left tool holder 22 of the drive element 21 and then the screw 17 in the direction of the right housing wall 9b is movable. By turning the left tool holder 22 by means of the tool 25 passes through the threaded portion 24b of the screw 17, the second hole 11 b of the right housing wall 9b and is then screwed into the right side wall 5 of the furniture body 2.
    On the other hand, FIG. 5 c shows that mounting situation in which the left housing wall 9 a is fastened via the screw 17 to the left side wall 4 of the furniture body 2. Starting from Fig. 5a, a tool 25 is inserted into the first hole 11b of the right housing wall 9b, whereupon the holding device 16 is releasable by applying pressure to the right tool holder 22 of the drive element 21 and then the screw 17 in the direction of the left housing wall 9a is movable , By rotation of the right tool holder 22 by means of the tool 25 passes through the threaded portion 24a of the screw 17, the second hole 11 b of the left housing wall 9a and is then screwed into the left side wall 4 of the furniture body 2.
    Fig. 6a shows a further embodiment of screws 17, which each have only a single threaded portion 24a, 24b. The threaded portion 24a is formed for screwing the screw 17 in the left side wall 4 of the furniture body 2, while the threaded portion 24b of the other screw 17 is screwed into the right side wall 5 of the furniture body. The arranged on the threaded portions 24a, 24b thread are doing with a different screw sense (once right-hand thread, once left-hand thread) execute. The axis of rotation (A) of the drive element 21 is arranged laterally offset relative to at least one axis of rotation (B) of the screw 17, preferably to both axes of rotation (B, C) of the screws 17.
    Fig. 6b shows the possibility that with a single drive element 21 and a plurality of screws 17 (four screws 17 in the present case) are driven. The screws 17 have teeth 19 which are all in engagement with an extended toothing 18 of the drive element 21. By rotation of the drive element 21 by means of a tool 25, the two threaded portions 24a in the left side wall 4 of the furniture body 2 can be screwed. When using the two other screws 17 for mounting the right housing wall 9b, the threaded portions 24b of the screws 17 are screwed into the right side wall 5 of the furniture body 2.
