DETAILED DESCRIPTION OF THE INVENTION

(10) FIG. 1 shows, in a perspective view, an item of furniture according to the present invention or a wall cupboard 1 with a box-like furniture body 2 and with a furniture part held thereon, which furniture part is in the form of a panel-like top flap 3 which is shown in an open position relative to the furniture body 2.

(11) The furniture body 2 comprises two opposite upright side walls 4 and 5, which are connected at the bottom to a bottom side 6 and at the top to a top side 7. At the rear, the furniture body 2 is closed off by a rear wall 8.

(12) For the movement of the top flap 3 about a horizontal pivot axis relative to the furniture body 2 from the open position shown in FIG. 1 into a closed position (not shown) in which the top flap has been moved onto the front side of the furniture body 2, a movement device according to the present invention is provided, which is designed as a top flap fitting 9. The top flap fitting 9 has a first fitting unit 10 at the side wall 4 and has a second fitting unit 11 at the side wall 5, which fitting units are of identical construction but are of side-specific design for the functionally correct arrangement on the respective side wall 4 or 5.

(13) Each fitting unit 10 and 11 comprises a base unit 12, guide 13 with a pivot arm arrangement 14, and a mounting unit 15. By means of multiple articulatedly mounted pivot arms of the pivot arm arrangement 14, the base unit 12 is connected to the mounting unit 15, which is fastened fixedly to an inner side of the top flap 3 so as to be recessed in a material recess.

(14) Furthermore, the guide 13 have a force store 21 for assisting the opening movement of the top flap 3 into the open position and a damper device 22 for a damped closing movement of the top flap 3 into the closed position.

(15) The base unit 12 is preferably formed from a sheet-metal component and comprises a planar, flat or thin anchor plate 16 and a flat thin housing plate 17 situated opposite the anchor plate 16 (see FIG. 3). The housing plate 17 is, in FIGS. 1 and 2, covered with a cover plate 18.

(16) Furthermore, at the face side on the base unit 12, there is provided a face portion 19, the outer side of which is oriented transversely with respect to the plane of the anchor plate 16. The respective pivot arms of the pivot arm arrangement 14 extend through a rectangular aperture 20 in the face portion 19. The width of the face portion 19, formed as a plug-on component, corresponds to a conventional width a of the side wall 4 of 16 millimeters. The total width or thickness of the fitting units 10 and 11 amounts to approximately 12 millimeters, such that accordingly the respective material aperture in the side walls 4 and 5 has a depth of likewise approximately 12 millimeters, resulting in a remaining base thickness of the side walls 4, 5 in the region of the respective material aperture of approximately 4 millimeters.

(17) FIG. 3 shows the fitting unit 10 without cover plate 18 and without face portion 19 in a pivoted-out position of the pivot arm arrangement 14. The housing plate 17 has been lifted off from the anchor plate, whereby components arranged at the inside on the anchor plate 16, such as the force store 21 and the damper device 22, can be seen.

(18) The pivot arm arrangement 14 has multiple pivot arms which are articulatedly connected to one another, and some of which are constructed from two spaced-apart pivot arm plates. Of the pivot arms, a pivot arm 23 and a pivot arm 24 will be highlighted below, which are articulatedly connected to one another by means of a further pivot arm. The pivot arm 23 is constructed from two spaced-apart pivot arm plates 23a and 23b of identical form, and the pivot arm 24 is likewise constructed from two spaced-apart pivot arm plates 24a and 24b of identical form. The respective pivot arm plates 23b and 24b directed toward the anchor plate 16 form a first outer side of the pivot arm arrangement 14, and the respective pivot arm plates 23a and 24a directed toward the housing plate 17 form a second outer side of the pivot arm arrangement 14. The two pivot arm plates 23a and 24a are in exact alignment with one another, as are the two pivot arm plates 23b and 24b. The pivot arm plates 23a, 23b and the pivot arm plates 24a, 24b are in each case connected to one another by means of rivet connections, wherein rivet heads 26 project at both sides, or in each case at the outside, from the pivot arm plates 23a, 23b and 24a, 24b somewhat, for example, in the range of tenths of a millimeter.

(19) The pivot arms 23 and 24 thus form a maximum width b of the pivot arm arrangement 14 (see FIG. 6), wherein, at the locations of the rivet connections of the pivot arm plates 23a, 23b and 24a, 24b, there is a slightly greater width than at the outer flat sides of the pivot arm plates 23a, 23b and 24a, 24b.

(20) The pivot arm 23 is pivotable about a pivot axis S provided by an axle pin 25, wherein the pivot axis S is oriented transversely with respect to an anchor plate plane GE spanned by the anchor plate 16. In FIGS. 1-4, the pivot arm arrangement 14 or the top flap 3 is situated in an open position in which it has been opened to a maximum extent or has been pivoted out to a maximum extent, whereas FIGS. 5-8 show the position of the pivot arm arrangement 14 in which it has been pivoted in to a maximum extent, without a mounting unit, in which the entire pivot arm arrangement 14 is accommodated in recessed fashion in the base unit 12 between the anchor plate 16 and the housing plate 17. In FIG. 8, portions of the closed top flap 3 and of the side wall 4 are indicated by dashed lines.

(21) In an intermediate region between the pivot arm arrangement 14 and the base unit 12, there are formed a positioning mechanism with a positioning portion.

(22) Specifically, by way of example, positioning portions designed as slide tracks 27-32 are provided both between the anchor plate 16 and the pivot arm arrangement 14 and between the housing plate 17 and pivot arm arrangement 14.

(23) In a front upper corner region in the interior of the base unit 12, there is provided a U-shaped slide element 33 with the opposite slide tracks 27, 28, wherein the slide tracks 27, 28 are in each case directed inward, that is to say the slide track 27 is directed toward the pivot arm plates 23b, 24b and the slide track 28 is directed toward the pivot arm plates 23a, 24a.

(24) Somewhat below the slide element 33, a strip-like slide element 34 with the slide track 29 is provided on the anchor plate 16 and is mirror-symmetrical with respect to an identical strip-like slide element 35 with the slide track 30, which is held on the housing plate 17. The slide track 29 is directed inward toward the pivot arm plates 23b, 24b, and the slide track 30 is directed inward toward the pivot arm plates 23a, 24a.

(25) Again somewhat below the slide elements 34, 35, a strip-like slide element 36 with the slide track 31 is provided on the anchor plate 16 and is mirror-symmetrical with respect to an identical strip-like slide element 37 with the slide track 32, which is held on the housing plate 17. The slide track 31 is directed inward toward the pivot arm plates 23b, 24b, and the slide track 32 is directed inward toward the pivot arm plates 23a, 24a.

(26) The slide elements 33-37 are positioned such that, over the course of an entire pivoting movement of the pivot arm arrangement 14, that is to say during the opening into the fully open position as per FIGS. 1 and 2, and during the closing movement into the fully closed position as per FIG. 8, none of the rivet heads 26 on the pivot arm plates 23a, 23b, 24a, 24b can pass or make contact with the slide tracks 27-32.

(27) In the ideal state of the pivot arm arrangement 14 in the case of an absolutely ideal position of all of its pivot arms with regard to the axial position in the direction of the pivot axis S, there is a relatively very narrow air gap 38 in each case between the respective slide tracks 27-32 and the respectively opposite portions of the pivot arm plates 23a, 23b, 24a, 24b.

(28) In practice, there is generally a slight misalignment of the pivot arm arrangement 14, or the pivot arms of the pivot arm arrangement 14 deviate slightly in an axial direction with respect to the pivot axis S from a setpoint bearing position, for example, in the range of tenths of a millimeter.

(29) These slight misalignments have hitherto been able to lead to undesired friction noises during the closing process of the top flap 3 or of the pivot arm arrangement 14.

(30) With the positioning mechanism according to the present invention, comprising the slide elements 33-37 with the slide tracks 27-32, in the case of misalignments of the pivot arm arrangement 14, the slide tracks 27-32 make abutting contact with the portions of the outer sides on the pivot arm plates 23a, 23b, 24a, 24b, wherein the outer sides on the pivot arm plates 23a, 23b, 24a, 24b form abutment surfaces which make sliding contact with the slide tracks 27-32.

(31) Since the slide tracks 27-32 are preferably composed of a friction-minimizing material, such as, for example, a Teflon material or a PTFE material, it is possible to realize a minimization of friction and/or noise in the event of misalignments of the pivot arm arrangement 14.

(32) Alternatively or additionally to the arrangement of slide elements attached to the base unit 12 or the anchor plate 16 and the housing plate 17, it is basically possible for slide elements with slide tracks to be attached to the outer sides of the pivot arm plates 23a, 23b, 24a, 24b and/or to the edge of the aperture 20 in the face portion 19.

(33) The attachment of the slide elements 34-37 to the anchor plate 16 and/or the housing plate 17 is advantageously realized in detachable fashion and manually by means of spigots 39 on the slide elements 34-37 and matching recesses 40. For example, multiple or three spigots 39 are provided in projecting fashion on that side of the slide elements 34-37 which is situated opposite the respective slide track 29-32, which spigots can be engaged with detent action into suitably prepared recesses 40 in the anchor plate 16 and/or in the housing plate 17.
