DETAILED DESCRIPTION OF THE INVENTION

(12) FIG. 1 shows a piece of furniture with a furniture body 1 and a furniture lid 2, wherein the furniture lid 2 is connected to the furniture body 1 by two lid fittings, of which one lid fitting 3 can be seen. The furniture body 1 has two parallel and vertically orientated side walls 4, of which one side wall 4 is visible. Furniture body 1 also has a bottom panel 5 and a top panel 6, which close the furniture body 1 at the top or bottom. At the rear, the furniture body 1 is closed off by a rear panel 7. Inside the furniture body 1 there is an intermediate shelf 8. On each side wall a lid fitting 3 is mounted.

(13) Furniture body 1 has an opening 9 pointing forward, through which the interior of furniture body 1 is accessible in the open position of lid fitting 3 shown in FIG. 1. FIG. 2 shows the lid fitting 3 in its closed position, in which the furniture lid 2 closes the opening 9.

(14) The lid fitting 3 is designed in such a way that it pivots the furniture lid 2, starting from the closed position shown in FIG. 2, to the open position over the top panel 6 of the furniture body 1 shown in FIG. 1. In principle, other lid fittings can also be provided, which adjust the furniture lid in parallel or which operate a furniture lid in the form of a folding lid.

(15) The side walls 4, the bottom panel 5 and the top panel 6 have end faces pointing towards the furniture lid 2, which together form an opening plane O. The opening plane O is arranged vertically in the shown arrangement of furniture body 1. In the closed position of the lid fitting 3, the furniture lid 2 is also in a vertical orientation parallel to the opening plane O. The furniture lid 2 has an inner surface facing towards the furniture body 1, which defines a lid plane D, which in the closed position of the lid fitting 3 is parallel to the opening plane O.

(16) The lid fitting 3 has a base element 10 which is attached to the side wall 4 of the furniture body 1. A pivot arm 11 is attached to the base element 10 so that it can pivot. On the pivot arm 11 a pivot-arm-side connecting element 12 is pivotably attached. To ensure that the pivot-arm-side connecting element 12 in the shown embodiment has a defined sequence of movements when opening and closing the furniture lid 2, a control arm 13 is provided, which is connected pivotably to the base element 10 on the one hand and pivotably to the pivot-arm-side connecting element 12 on the other.

(17) A lid-side connecting element 14 is connected to the pivot arm-side connecting element 12. The lid-side connecting element 14 has a flat mounting surface 15 which lies against the inner surface 16 of the furniture lid 2 and is connected to the furniture lid 2 via the lid-side connecting element 14. For this purpose, the lid-side connecting element 14 is connected to the furniture lid 2 via fastening screws 30 (FIGS. 6 to 10).

(18) FIGS. 5 and 6 show a lateral sectional view of the furniture body 1, with the lid-side connecting element 14 in an assembly position prior to assembly with the pivot-arm-side connecting element 12. When mounting the lid fitting 3, the lid fitting 3 is first attached to the side wall 4 of the furniture body 1 via the base element 10. The lid fitting 3 is in an assembly position close to the closed position. In the assembly position, the pivot-arm-side connecting element 12 is arranged offset inwards in the furniture body 1 by a certain amount. FIG. 6 shows that the pivot-arm-side connecting element 12 is arranged at a first distance a1 from the opening plane O and is therefore completely inside the furniture body 1. When the lid-side connecting element 14 is mounted (FIG. 10), the pivot-arm-side connecting element 12 is pivoted or moved out of the furniture body 1 by a certain amount. FIG. 10 shows that the pivot-arm-side connecting element 12 protrudes outwards from the opening of the furniture body 1 by the distance a2. However, it is not absolutely necessary for the pivot-arm-side connecting element 12 to protrude from the furniture body 1; it is sufficient if it is only moved slightly away from the assembly position towards the open position.

(19) The pivot arm 11 is force-loaded via a power drive not shown in its closed position according to FIG. 10 in the direction towards the assembly position according to FIG. 6, so that the furniture lid 2 is pulled against the furniture body 1 to ensure secure closing of the furniture body 1. In order to compensate for assembly tolerances, there must therefore be a certain adjustment path, starting from the closed position according to FIG. 10, towards the assembly position according to FIG. 6. In principle, it is also possible that the lid fitting 3 does not have a power drive.

(20) Usually, to mount the furniture lid 2, the lid fitting 3 or the pivot arm 11 is moved into its open position so that the pivot arm-side connecting element 12 is outside the furniture body 1 and the lid-side connecting element 14 can be connected to the pivot arm-side connecting element 12.

(21) According to the invention, however, it is provided that the pivot arm 11 is moved out of the furniture body 1 by a transverse movement of the lid-side connecting element 14 in an assembly direction M (FIG. 5) parallel to the lid plane D or parallel to the opening plane O the pivot arm-side connecting element 12 is moved out of the assembly position according to FIG. 6 to the closed position.

(22) For this purpose, the pivot-arm-side connecting element 12 has a ramp surface 17 which runs at an angle to the mounting surface 15 of the lid-side connecting element 14 in the assembly direction M. The lid-side connecting element 14 has a sliding element 18, which is pin-shaped and arranged parallel to the mounting surface 15 or to the lid plane D and perpendicular to the assembly direction M. Alternatively, the ramp surface 17 can also be arranged on the lid-side connecting element 14, in which case the sliding element 18 must be arranged on the pivot-arm-side connecting element 14.

(23) The ramp surface 17 is designed in the illustrated exemplary embodiment in such a way that the distance of the ramp surface 17 to the opening plane O increases in assembly direction M. In the present case, the assembly direction M is vertically aligned so that the lid-side connecting element 14 is moved vertically downwards for mounting. Alternatively, it is also possible that the assembly direction M leads vertically upwards. This can be particularly important if the furniture body 1 has a crown bar on the top panel 6 so that the furniture lid 2 cannot be moved upwards over the furniture body 1 in the opening plane O.

(24) The furniture lid 2 is placed against the opening 9 of the furniture body 1, whereby the sliding element 18 projects further into the opening or is further away from the opening plane O than the smallest distance of the ramp surface 17 to the opening plane O. Thus, when the lid-side connecting element 14 moves in the assembly direction M, the sliding element 18 engages behind the ramp surface 17 and comes into contact with it. When the lid-side connecting element 14 is moved further in assembly direction M, the pivot-arm-side connecting element 12 is pulled out of the furniture body 1 in the direction towards the lid-side connecting element 14 or in the direction towards the furniture lid 2 due to the ramp surface 17 running at an angle to the assembly direction M. In FIG. 7, the pivot-arm-side connecting element 12 has already been pulled out of the furniture body 1 to such an extent that it is approximately flush with the opening plane O.

(25) When the lid-side connecting element 14 continues to move, the sliding element 18 also comes into contact with a supporting surface 19, which is arranged opposite the ramp surface 17. The supporting surface 19 is arranged in such a way that an upwardly opening gap 31 with a wedge-shaped cross-section is formed between the ramp surface 17 and the supporting surface 19, into which the sliding element 18 is immersed. As soon as the sliding element 18 is immersed far enough in this gap 31, it is axially supported against the ramp surface 17 in one direction transverse to the assembly direction M and against the supporting surface 19 in the opposite direction.

(26) At a lower end the ramp surface 17 and the supporting surface 19 are connected by an arch section. In the fully assembled position, the sliding element 18 is located at the bottom of the gap 31 between the ramp surface 17 and the supporting surface 19, whereby the sliding element 18 has passed and locked behind locking projections 20, 21 on the ramp surface 17 and on the supporting surface 19, so that it cannot be pulled out of the gap 31 against the assembly direction without a certain amount of force.

(27) A fixation device 22 is provided for fixing the lid-side connecting element 14 to the pivot arm-side connecting element 12. This has a latching element 23 on the lid-side connecting element 14, which is pin-shaped like the sliding element 18 and is arranged parallel to it. In the assembled state, the latching element 23 engages behind a catch hook 24 of the fixation device 22 on the pivot arm-side connecting element 12 and is secured against displacement against the assembly direction M.

(28) Alternatively, the catch hook 24 can also be arranged on the lid-side connecting element 14 and the latching element 23 on the pivot arm-side connecting element.

(29) The catch hook 24 is adjustable between a fixing position shown in FIGS. 6, 7, 8 and 10 and a release position shown in FIG. 9. To adjust the catch hook 24, it has an insertion slope 25 which forms an acute angle with the assembly direction M. When the lid-side connecting element 14 is moved in the direction of assembly direction M, the latching element 23 first comes into contact with the insertion slope 25 of the catch hook 24 and presses the catch hook 24 from its fixing position into its release position (FIG. 9). When moving further in assembly direction M, the catch hook 24 springs back into its fixing position and secures the latching element 23 (FIG. 10).

(30) For manual adjustment of the catch hook 24, the fixation device 22 also has a unlocking lever 28, by means of which the catch hook 24 can be adjusted manually. The catch hook 24 is subjected to force in the direction towards its fixing position via a spring element 27, the spring element 27 being arranged on a pivot pin 26 about which the catch hook 24 can be pivoted.

(31) The pivot-arm-side connecting element 12 has a securing recess 29, in which, in the assembled state of the lid-side connecting element 14, the latching element 23 engages as a securing element. In the embodiment shown, the latching element 23 thus has two functions. On the one hand, the latching element secures the lid-side connecting element 14 on the pivot arm-side connecting element 12 against displacement in and against the assembly direction M by engaging behind the catch hook 24. On the other hand, the latching element 23 secures the lid-side connecting element 14 against displacement transverse to the assembly direction M by engaging in the securing recess 29. The latter function can alternatively be fulfilled by a separate securing element, for example in the form of a separate pin-shaped element.

(32) Further, the securing element can alternatively be arranged on the pivot-arm-side connecting element 12, the securing recess 29 then being arranged on the lid-side connecting element 14.
