DETAILED DESCRIPTION OF THE INVENTION

(8) FIG. 1a shows an article of furniture 16 having a furniture body 3 and a furniture part 2 upwardly movable relative to the furniture body 3. The upwardly movable furniture part 2, in this figure, is in the form of a furniture flap. In addition, arranged at the two side walls 9a, 9b is a respective furniture drive 1, and each of the furniture drives 1 has a drive unit 4 and at least one moveably mounted actuating portion 5. The furniture part 2, in this case, is movable by the actuating portions 5 between a closed position and a position of being lifted relative to the furniture body 3. In FIG. 1, the furniture part 2 is shown in a lifted position. The actuating portions 5 can also have a multi-part structure. The furniture drive 1 arranged at the side wall 9b has, for example, three actuating arms 5a, 5b, 5c hingedly connected to one another. In this connection, it is additionally noted that the actuating portions 5 do not have to be connected directly to the furniture part 2. An indirect connection by further levers and/or fitments can also be provided.

(9) FIG. 1b shows a wall 9 and a portion of a top wall 15 of a furniture body 3. The furniture drive 1, in this case, is not yet positioned at a predetermined mounting position. In addition, the furniture drive 1 has a drive unit 4, a movably mounted actuating portion 5, a substantially T-shaped mounting abutment 6 and two abutments 6a. The mounting abutment 6, in this case, is mounted movably relative to the drive unit 4. The two abutments 6a serve for positioning in respect of height of the drive unit 4 in the furniture body 3. The top wall 15 has an underside 14, wherein the abutments 6a can be bear against that underside 14 of the top wall 15.

(10) FIG. 2a shows a wall 9 and a portion of a top wall 15 of a furniture body 3. The top wall 15 has an underside 14, and the two abutments 6a can bear against the underside 14. Once again, the furniture drive 1 has a drive unit 4, an actuating portion 5 mounted pivotably relative to the drive unit 4, a mounting abutment 6 and the two above-mentioned abutments 6a. The substantially T-shaped mounting abutment 6 serves for bearing against the front face 8 of the wall 9. As a difference in relation to FIG. 1b, the abutment 6a shown at the left in the view is already bearing against the underside 14 of the top wall 15 and thus the drive unit 4 is pre-positioned in respect of height in the furniture body 3. The abutment 6a shown at the right is subsequently to be bear against the underside 14 of the top wall 15.

(11) FIG. 2b shows the wall 9 and a portion of the top wall 15 of the furniture body 3. The illustrated furniture drive 1 is now positioned at a predetermined mounting position on the wall 9 in the furniture body 3. The two abutments 6a serving for heightwise positioning of the drive unit 4 bear against the underside 14 of the top wall 15. The mounting abutment 6 is applied to the end 8 of the wall 9, so that the drive unit 4 is positioned in respect of depth in the furniture body 3.

(12) By virtue of a flat side of the drive unit 4 bearing against the wall 9, the drive unit 4 is fixed in all directions in the furniture body 3 at a predetermined mounting position. In contrast to FIG. 2a, the mounting abutment 6 is shown in a pivoted and displaced position so that the mounting abutment 6 can be applied to the front face 8. As an alternative thereto, it is also possible for a flat side of the drive unit 4 to bear against the underside 14 of the top wall 15, so that the mounting abutment 6 can be applied to the front face 17 of the top wall 15.

(13) FIG. 2c shows an enlarged view of the region circled in FIG. 2b. In this respect, it can be seen that the mounting abutment 6 has an axis of symmetry S, and the mounting abutment 6 has a structure of mirror-image symmetry with respect to the axis of symmetry S. Therefore, the mounting abutment 6 can be selectively applied by a movement towards the left or towards the right against two different front faces 8, 8a of two mutually opposite side walls 9a, 9b of the furniture body 3. Accordingly, the illustrated furniture drive 1 can be positioned both at left and also at right side walls 9a, 9b of a furniture body 3. In addition, the mounting abutment 6 has the two abutment surfaces 12, 12a arranged symmetrically relative to the axis of symmetry S. In FIG. 2c, the abutment surface 12 is applied against the front face 8.

(14) FIG. 3a shows a perspective view of the furniture drive 1, wherein the drive unit 4 includes a mounting abutment 6 mounted movably by a pin 10. In addition, the drive unit 4 has a mounting plate 7 serving for fixing the drive unit 4 to a wall 9. Furthermore, there is provided a spring device 13 for applying a force to the actuating portion 5.

(15) FIG. 3b shows an enlarged view of the region circled in FIG. 3a. In that respect, the two abutment surfaces 12, 12a of the mounting abutment 6 can be clearly seen, and those two abutment surfaces 12, 12a serve for bearing against the front faces 8, 8a of two mutually opposing side walls 9a, 9b. It is also possible to see the axis A, about which the mounting abutment 6 is mounted pivotably. The drive unit 4 has a recess 20 for receiving the mounting abutment 6. The mounting abutment 6 has a first leg 18 and a second leg 19. The width of the first leg 18 is less than the width of the recess 20 and the width of the second leg 19 approximately corresponds to the width of the recess 20. Therefore, displacement of the mounting abutment 6 along the pin 10 or along the axis A in the direction R is possible only after an at least partial pivotal movement of the mounting abutment 6 relative to the drive unit 4. The actuating portion 5 (not visible in this Figure) is mounted pivotably relative to the drive unit 4 about the axis of rotation D, and the axis of rotation D and the axis A extend substantially parallel to each other. The direction R in which the mounting abutment 6 is displaceable also extends in parallel spaced relationship with the axis of rotation D.

(16) FIG. 4a shows a perspective view of the furniture drive 1. As a difference in relation to FIG. 3a, the mounting abutment 6 is shown in a pivoted position. It is also possible to see the mounting plate 7 which is suitable for fixing the drive unit 4 to a wall 9 by screws or dowels (not shown).

(17) FIG. 4b shows a detail view of FIG. 4a. With regard to the axis of rotation D of the actuating portion 5 and the direction R, reference is directed to the description of FIG. 3b. In addition, the recess 11 of the drive unit 4 into which the mounting abutment 6 can be at least partially received in its first position as shown in FIG. 3a is clearly visible.

(18) FIG. 5a shows the furniture drive 1 according to FIG. 4a with a further position of the mounting abutment 6 which, in addition to the pivoted position in FIG. 4a, is also displaced towards the left along the pin 10.

(19) FIG. 5b shows another perspective view of the circled region in FIG. 5a. In order for the mounting abutment 6 to be held in the second position in a predetermined location, the mounting abutment 6 has a flattened region 21. A further flattened region 21 is also provided symmetrically relative to the axis of symmetry S on the other side. In that way, the mounting abutment 6 is also held in a predetermined position in the position of being displaced towards the right along the pin 10. The mounting abutment therefore does not drop down under its own weight in the position of being displaced towards the left or towards the right. The references to “up” and “down” respectively refer to the usual mounted position of the furniture drivel.

(20) FIG. 5c shows a further perspective view of the detail region shown in FIG. 5b. In this respect, it is possible to see the recess 11 provided for at least partially receiving the mounting abutment 6 in its first position.

(21) FIG. 6a shows a cross-sectional view of the mounting abutment 6 along the axis of symmetry S of the mounting abutment 6. The mounting abutment 6 is mounted movably by the pin 10 relative to the drive unit 4 and is in the first position in this Figure. It is also possible to see the axis A, about which the mounting abutment 6 is mounted pivotably and is displaceable along that axis A.

(22) FIG. 6b shows the mounting abutment 6, in contrast to FIG. 6a, in a position of being pivoted about the pin 10.

(23) FIGS. 6c and 6d show the mounting abutment 6 in a position of being displaced along the pin 10. That position respectively corresponds to the second position of the mounting abutment 6. Furthermore, that position corresponds to the mounted state of the furniture drive 1, and the drive unit 4 of the furniture drive 1 in this position can be positioned both in respect of height and also in respect of depth on or in the furniture body 3. It can also be seen from these two Figures that the flattened region 21 of the mounting abutment 6, shown in FIG. 5b, at least partially bears against the drive unit 4 in the second position and thus the mounting abutment 6 is prevented from dropping down under its own weight.

(24) The method according to the invention for mounting the furniture drive 1 is described with reference to FIGS. 1b, 2a and 2b. In that respect, the following steps are performed: moving the drive unit 4 into a position until the mounting abutment 6 bears against the front face 8 of the wall 9 of the furniture body 3, so that the drive unit 4 is positioned in respect of depth at a predetermined mounting position in the furniture body 3, fixing the drive unit 4 at the predetermined mounting position in the furniture body 3, preferably by means of screws or dowels (not shown).

(25) The following step can be provided prior to the movement of the drive unit 4: pivoting and/or displacing the mounting abutment 6 relative to the drive unit 4 into a second position in which the mounting abutment 6 projects transversely from the drive unit 4, so that the mounting abutment 6 can bear against a front face 8 of the furniture body 3.

(26) In addition, the following step can be performed prior to or after fixing of the drive unit: pivoting and/or displacing the mounting abutment 6 relative to the drive unit 4 into a first position in which the mounting abutment 6 is at least partially received in a recess 11 of the furniture drive 1.

(27) In that respect, the following step can be performed prior to fixing of the drive unit: moving the drive unit 4 into a position until at least one of the abutments 6a of the drive unit 4, that are separate from the mounting abutment 6, bears against the underside 14 of the top wall 15 of the furniture body 3, so that the drive unit 4 is positioned in respect of height at a predetermined mounting position in the furniture body 3.

(28) It is noted at this juncture that it is not absolutely necessary for the movement of the drive unit 4 for heightwise position to be carried out prior to the movement of the drive unit 4 for positioning in respect of depth. That can also be carried out in the reverse sequence.

(29) To facilitate the movement of the drive unit 4, the drive unit 4 can bear against the wall 9 of the furniture body 3 during the positioning movement and can be displaced along that wall 9.
