DETAILED DESCRIPTION OF THE INVENTION

(19) FIG. 1 shows in perspective an item of furniture according to the present invention, or a wall unit 1 having a box-shaped furniture carcass 2 and a furniture part received thereon which takes the form of a panel-like upper flap 3 which is shown in an open position relative to the furniture carcass 2.

(20) The furniture carcass 2 comprises two opposite, upright side walls 4 and 5 which are connected at the bottom to an underside 6 and at the top to an upper side 7. The furniture carcass 2 is closed on the rear side by a rear wall 8.

(21) To move the upper flap 3 about a horizontal pivot axis relative to the furniture carcass 2 from the open position shown in FIG. 1 into a closed position (not shown) in which it is moved up on the front side to the furniture carcass 2, a movement device according to the present invention is present which is configured as an upper flap fitting 9. The upper flap fitting 9 has a first fitting unit 10 on the side wall 4 and a second fitting unit 11 on the side wall 5, the fitting units being constructed identically but, for functionally correct arrangement on the respective side wall 4 or 5, in a side-relevant manner.

(22) Each fitting unit 10 and 11 comprises a base unit 12, guide 13 having articulated levers, and a mounting unit in the form of a mounting plate 15a, 15b. A plurality of articulately mounted articulated levers which are present as pivot or lever arms of a pivot arm arrangement 14 serve to connect the base unit 12 to the mounting plate 15a, 15b, which is fastened securely to an inner side of the upper flap 3, for example, so as to be sunk in a material recess.

(23) FIGS. 3 and 4 illustrate a side view of the guide 13a in a first design variant, FIG. 4 showing parts of the guide 13a in phantom.

(24) FIG. 5 illustrates a detail view B of the guide 13a. An articulated lever 16 and a lever arm 17a of a further articulated lever 18 formed in a sandwich-like manner are shown in FIG. 5. The articulated lever 18 comprises two lever arms 17a, 17b. The articulated lever 16 comprises a single lever arm and is present in the arranged state between the lever arms 17a, 17b of the articulated lever 18. An attachment member in the form of an opening 20 is formed on the articulated lever 16 at an attachment region 19. Extending around the opening 20 on a first side 21 of the articulated lever 16 in the radial direction is a first embossing 29 in the form of elevations 22 to 24 and depressions 25 to 27. The elevations 22-24 and depressions 25-27 are advantageously present in a circular segment-like manner. The elevations 22-24 and depressions 25-27 are advantageously designed to be offset in the image plane with respect to a remaining surface 28 of the first side 21. A rivet member 30 is additionally shown in the opening 20. The articulated lever 16 advantageously comprises two attachment regions 19, 31.

(25) The first embossing 29 and a second embossing 32 are shown in the detail view C (FIG. 7) of the articulated lever 16. The embossing 32 is situated at the attachment region 19 on a second side 33 opposite to the first embossing 29, parts of the second embossing 32 being designed to be raised or sunk with respect to a remaining surface 34 of the second side 33 of the articulated lever 16. A depression 26 of the first embossing 29 is advantageously designed to be opposite to an elevation 35 of the second embossing 32. A thickness or width d of the articulated lever 16 is advantageously formed by a spacing of the remaining surface 28 of the first side 21 from the remaining surface 34 of the second side 33 of the articulated lever 16. A spacing of a surface 41 of the elevation 35 of the second embossing 32 from a surface 42 of the depression 26 of the first embossing 29, or vice versa, is advantageously equal to the width d of the articulated lever 16.

(26) FIG. 9 illustrates a lever arm 36 of a further articulated lever 37 of the guide 13a. The lever arm 36 advantageously comprises three attachment regions 38-40. The articulated levers 18, 37, which particularly have a single lever arm, are advantageously arranged next to one another in one plane in the arranged state on the guide 13a (see FIG. 4).

(27) FIGS. 10 to 14 show guide 13b with a further variant of embossings. An articulated lever 43 having two attachment regions 44, 45 is shown in FIGS. 10 to 14. The embossings 50, 51 of the attachment regions 44, 45 have circular elevations 47, 49 and depressions 46, 48. As viewed in the radial direction about an opening 52, 53 of an attachment region 44, 45, the elevation and depression of an embossing 50, 51 are designed to extend in an alternating manner. An attachment region 44 advantageously comprises two embossings 50, 54, a first embossing 50 on a first side 55 and a second embossing 54 on a second side 56 of the articulated lever 43 being arranged opposite to one another. In the variant according to FIGS. 10 to 14, an elevation 49 of the first embossing 50 has different circle areas with respect to an elevation 57 of the second embossing 54 of the attachment region 44. For example, an outside diameter D1 of the elevation 57 of the second embossing 54 is identical to an inside diameter of the elevation 49 of the first embossing 50. An outside diameter D2 of the elevation 49 of the first embossing 50 is, for example, greater than the outside diameter D1 of the elevation 57 of the second embossing 54. The same conversely applies, for example, to the depressions of the embossings 50, 54.

(28) A sectional view through the attachment region 19 of the guide 13a is shown in FIG. 17. The articulated lever 16, the lever arms 17a, 17b of the articulated lever 18 and the rivet member 30 are shown. The rivet member 30 consists of three cylindrical elements 58-60 which are formed in one piece with one another. The central element 59 of the rivet member 30 has a greater outside diameter than the two outer elements 58, 60. The rivet member 30 is advantageously formed in such a way that it can be inserted by the central element 59 into the opening 20 of the articulated lever 16, advantageously with an accurate fit.

(29) End faces of the central element 59 advantageously form bearing surfaces 63, 64 for inner surfaces 65, 66 of the lever arms 17a, 17b of the articulated lever 18. In the arranged state, the lever arms 17a, 17b are advantageously mounted so as to be movable on the bearing surfaces 63, 64 of the central element 59. In addition, the inner surfaces 65, 66 of the lever arms 17a, 17b of the articulated lever 18 are preferably mounted so as to be movable on bearing surfaces 67, 68 of elevations of the embossings 29, 32 of the articulated lever 16 in the arranged state. The elevations of the embossings 29, 32 of the articulated lever 16 advantageously form, with the bearing surfaces 63, 64 of the rivet member 30, bearing planes or support planes for the inner surfaces 65, 66 of the lever arms 17a, 17b of the articulated lever 18.

(30) In the arranged state, the outer elements 58, 60 advantageously extend beyond an outer surface 61, 62 of the lever arms 17a, 17b. As a result, the outer elements 58, 60 of the rivet member 30 can, for example, be orbitally formed by means of an orbital riveter, in particular deformed, with the result that, after the orbital forming or deformation, the rivet member 30 interconnects the articulated levers 16, 18 particularly in a movable and nonreleasable manner.
