    专利说明:

    The present invention relates to a furniture fitting comprising: at least one fastening device for fastening the furniture fitting to a furniture part, the fastening device having at least two fastening elements insertable in an opening, in particular a cylindrical bore, of the furniture part and at least one rotatably mounted locking element, wherein the at least two fastening elements are movable by a rotation of the locking element in a first rotational direction starting from a starting position relative to each other and thus in a spread position, in which the at least two fastening elements in the opening of the furniture part can be locked, and wherein the at least two fasteners by a rotation of the locking element in a second rotational direction of the opening can be solved.
    Furthermore, the invention relates to an arrangement with a furniture part and with a furniture fitting of the type to be described.
    Such furniture fittings are known for example from EP 0 698 357 B1 of the Applicant and serve to assemble or disassemble the furniture fitting without the use of a tool on furniture parts. For mounting, a fastening element in the form of a dowel is firstly inserted in a cylindrical bore of a furniture part, whereupon a spreading part for the dowel can be moved by turning or tilting a fitting body, so that the dowel is widened into an expanded position and thus fixable within the bore. To disassemble the furniture fitting of the fitting body is moved back so that the anchor assumes a release position and thus can be pulled out of the hole. This dismantling of the furniture fitting is often difficult because the dowel is in the release position with the inner wall of the bore in partial frictional contact and thus the withdrawal of the dowel is impeded from the bore.
    Object of the present invention is therefore to provide a furniture fitting of the type mentioned above while avoiding the above drawback.
    This is solved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.
    According to the invention it is thus provided that the at least two fastening elements are retractable by rotation of the locking element in the second direction of rotation from the spread position to the starting position.
    Thus, the at least two fasteners are actively retracted by a rotation of the locking element in the second direction of rotation to the starting position, so that the fasteners form in this compact starting position the lowest possible common diameter and thus are easier to remove from the bore during disassembly of the furniture fitting. The fastening elements are thus forcibly guided with the locking element in both directions of rotation or mechanically coupled, so that the at least two fastening elements move relative to one another during a rotation of the locking element.
    For spring-assisted movement of the fastening elements into the starting position, at least one energy accumulator can be provided by which the fastening elements are prestressed in the direction of the starting position. This energy storage, for example, have a spring element in the form of a coil spring (in particular a tension spring) or in the form of a spring tongue. Alternatively, the force accumulator may comprise at least one elastic band which at least partially surrounds the at least two fastening elements and thereby presses the fastening elements into the compact starting position.
    In a further embodiment, it can be provided that the at least two fastening elements are adjustably mounted by a rotation of the locking element by less than 360 °, preferably less than 180 °, between the expanded position and the starting position. This can be realized, for example, by at least one high pitch thread (i.e., two or more pitch compared to a standard thread) disposed on the locking element.
    A variant of the invention results from the fact that the at least two fastening elements are mounted linearly displaceable furniture fitting and are linearly displaceable by a rotation of the locking element in the first and / or second direction of rotation furniture furniture. Again, this results in a simple assembly and disassembly of the furniture fitting, since the two fasteners are mounted linearly displaceable in a direction perpendicular to the axis of rotation of the locking element between the starting position and the spread and thus without tilting evenly against the inner wall of the opening of the furniture part be pressed and moved away from this. In the spread position of the fasteners in which they are locked in the opening of the furniture part, which is provided for contact with the opening surface of the fastener elements completely together with the inner wall of the opening. Thus, an enlarged contact surface of the fasteners is available, which rests against the inner wall of the opening, wherein the forces are distributed over a larger area and wherein point or line contacts are avoided with high surface pressure. In this way, the maintenance of the fasteners can be improved in the opening, especially if the furniture parts are designed with thin wall thickness and / or fibrous material, such as chipboard, exist.
    Further details and advantages of the invention will be explained in the following description of the figures. It shows or show:
    1a, 1b an embodiment of a furniture fitting in the form of a furniture hinge in a cross section, wherein the fasteners are in a starting position, and an enlarged detail illustration of this,
    Fig. 2a, 2b of the furniture fitting of FIG. 1 with the fastening elements in a spread position, and an enlarged detail illustration thereof, Fig. 3 of the furniture fitting in an exploded view.
    Fig. 1a shows a perspective cross-section of a furniture fitting 1 in the form of a furniture hinge, which is designed as a wide-angle hinge with seven hinge axes. The furniture fitting 1 comprises a first stop member 4 to be fastened to a furniture body 2 and a second stop member 5 to be fastened to a movable furniture member 3, wherein the first stopper member 4 and the second stopper member 5 are pivotally connected to each other via a plurality of hinge levers 6a, 6b, 6c, 6d are. For attachment of the second stop member 5 on the movable furniture part 3, two fastening devices 7 are provided, which are identical and by means of which the invention is to be explained.
    The fastening devices 7 each comprise a locking element 8 rotatably mounted about an axis of rotation (for example in the form of a screw), wherein the locking elements 8 are each provided with a tool holder 9 for rotating the locking element 8. In the movable furniture part 3, an opening 11, in particular a cylindrical bore, predrilled, in which at least two fastening elements 10a, 10b are inserted and by a rotation of the locking element 8 in a first rotational direction, starting from a starting position relative to each other and movable into an expanded position can be locked, in which the at least two fastening elements 10a, 10b in the opening 11 of the furniture part 3 can be locked, and wherein the at least two fasteners 10a, 10b retractable by rotation of the locking element 8 in a second direction of rotation in the starting position and thus from the opening 11 are detachable. In the figure shown, the fastening elements 10a, 10b are in the starting position, in which the fastening elements 10a, 10b can be pulled out of the opening 11 of the furniture part 3.
    Fig. 1b shows the circled in Fig. 1 a area in an enlarged view. The furniture fitting 1 has at least one, preferably arranged on a flange 12, guide 13 for linearly displaceable mounting of the fastening elements 10a, 10b, which mounted by a rotation of the locking element 8 in a direction perpendicular to the axis of rotation of the locking element 8 along this guide 10 slidably are. The
    Locking element 8 is provided with at least one helical thread 14 which cooperates with a mating thread 15 arranged on the fastening elements 10a, 10b.
    Fig. 2a shows the furniture fitting 1, wherein the two fastening elements 10a, 10b are in an expanded position in which the two fastening elements 10a, 10b in the opening 11 (Fig. 1 b) of the movable furniture part 3 are locked. Starting from the position shown in Fig. 1b, the two fasteners 10a, 10b were moved by rotation of the locking member 8 in a first rotational direction, starting from the starting position in opposite directions relative to each other and thus pressed into a spread position. The two fastening elements 10a, 10b are mounted linearly displaceably on the furniture fitting 1 along the guide 10 and are linearly displaceable by a rotation of the locking element 8 in the first and / or second rotational direction along the guide 10. For rotation of the locking element 8, a tool holder 9 may be provided for a screwdriver, alternatively, it is also possible that the locking element 8 is designed for manual operation (for example via a manually operated pivoting lever). Starting from the spread position shown in Fig. 2b, in which the two fasteners 10a, 10b abut each flat against the inner wall of the opening 11, the fasteners 10a, 10b by rotation of the locking element 8 in the opposite, second direction of rotation back into the in FIG 1b starting position shown retractable. In the exemplary embodiment shown, the locking element 8 is connected to the two fastening elements 10a, 10b via a tapered thread 16 in connection. It can be provided that the tapered thread 16 has such a slope that the at least two fastening elements 10a, 10b by a rotation of the locking element 8 by less than 360 °, preferably less than 180 °, starting from the spread position in the starting position (or. also in the opposite direction) are movable. In order to prevent unintentional release of the spread, the locking element 8 may also be secured by a (not shown here) releasable locking device.
    Fig. 3 shows the furniture fitting 1 in an exploded view. On the flange 12 of the furniture fitting 1, a guide 13 for linearly displaceable mounting of the at least two fastening elements 10a, 10b is arranged, which are displaceably mounted by rotation of the locking element 8 along the guide 13 in opposite directions. The tapered thread 16 of the locking element 8 has at least one helical thread 14, which is in engagement with a corresponding mating thread 15 of the fastening elements 10a, 10b. For the spring-assisted retraction movement of the fastening elements 10a, 10b into the starting position, at least one force store 17 is provided by which the fastening elements 10a, 10b are biased in the direction of the starting position. In the exemplary embodiment shown, the force accumulator 17 is formed by two spring tongues 20 which are arranged on the first fastening element 10a and which engage with the second fastening element 10b. The two spring tongues 20 of the first fastening element 10a thus encompass the second fastening element 10b, wherein in the initial position a concave contour 21 of the spring tongues 20 abuts each on a convex mating contour 22 of the second fastening element 10b. By a rotation of the locking element 8 in the first direction of rotation, the two fastening elements 10a, 10b are moved away from each other, so that the spring tongues 20 are expandable against its resilient action. Upon rotation of the locking member 8 in the second, opposite direction of rotation, the two fasteners 10 are contracted by the force of the relaxing spring tongues 20 and thus pressed back into the starting position in which the fasteners 10a, 10b practically without frictional resistance from the opening 11 of Furniture part 3 can be pulled out. To improve the holding force in the clamping position, the fastening elements 10a, 10b designed as half-shells may have at least one or more retaining ribs 19 on their arcuate surface provided with the contact with the opening 11 of the furniture part 3. The holding ribs 19 are arranged or formed with respect to the longitudinal direction of the arresting element 8 at a distance from one another on the fastening elements 10a, 10b.
    In the figures shown, the furniture fitting 1 according to the invention has been explained with reference to a furniture hinge. However, it is immediately obvious that the furniture fitting 1 can also be designed alternatively, namely as a drawer extension, as an actuator for furniture flaps or as
    Holding device for a functional part, preferably a damping device for damping a movement of a movable furniture part and / or a drive device for moving a movable furniture part.
