Representation, as well as an enlarged detail of this, the furniture drive according to Figure 1 a in a perspective view, as well as two enlarged detail views this, the mounting stop in different positions. FIG. 1 a shows a piece of furniture 16 which has a furniture body 3 and a furniture part 2 which is highly movable relative to the furniture body 3. The highly movable furniture part 2 is formed in this figure as a furniture flap. Furthermore, in each case a furniture drive 1 is arranged on the two side walls 9a, 9b, the furniture drives 1 each having a drive unit 4 and at least one movably mounted setting part 5. The furniture part 2 is movable by the adjusting parts 5 between a closed position and a relative to the furniture body 3 raised position. The furniture part 2 is shown in Figure 1 in a raised position. The actuators 5 may also have a multi-part construction. The arranged on the side wall 9b furniture drive 1, for example, has three actuating arms 5a, 5b, 5c, which are hinged together. In this context, it should also be noted that the control parts 5 need not be connected directly to the furniture part 2. It may also be provided an indirect connection via other levers and / or fittings. Figure 1 b shows a wall 9 and a portion of a top wall 15 of a furniture body 3. The furniture drive 1 is not yet positioned at a predetermined mounting position. Furthermore, the furniture drive 1 has a drive unit 4, a movably mounted actuating part 5, a substantially T-shaped mounting stop 6 and two stops 6a. The mounting stop 6 is mounted movable relative to the drive unit 4. The two stops 6a are used for height positioning of the drive unit 4 in the furniture body 3. The top wall 15 has an underside 14, wherein the stops 6a can be applied to this underside 14 of the top wall 15. Figure 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, wherein on this underside 14, the two stops 6a can be applied. Again, the furniture drive 1, a drive unit 4, a relative to the drive unit 4 pivotally mounted control part 5, a mounting stop 6 and the two abovementioned stops 6a. The im Essentially T-shaped mounting stop 6 is used to rest against the end face 8 of the wall 9. In contrast to Figure 1 b of the left stop 6a according to the presentation is already applied to the underside 14 of the top wall 15 and thus the drive unit 4 in terms of height prepositioned in the furniture body 3 , the stop 6 a shown on the right is then to be applied to the underside 14 of the top wall 15.

Figure 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 stops 6a, which serve for the height-positioning of the drive unit 4, lie against the underside 14 of the top wall 15. The mounting stop 6 is applied to the end face 8 of the wall 9, so that the drive unit 4 is positioned deep in the furniture body 3. By investing a flat side of the drive unit 4 on the wall 9, the drive unit 4 is thus set in all directions in the furniture body 3 at a predetermined mounting position. In contrast to Figure 2a, the mounting stop 6 is shown in a pivoted and shifted position, so that the mounting stop 6 can be applied to the front page 8. Alternatively, it is also possible to apply the drive unit 4 with a flat side to the underside 14 of the top wall 15, so that the mounting stop 6 on the end face 17 of the top wall 15 can be applied.

FIG. 2c shows the area circled in FIG. 2b in an enlarged view. It can be seen that the mounting stop 6 has an axis of symmetry S, wherein the mounting stop 6 is constructed with mirror symmetry with respect to the symmetry axis S, so that the mounting stop 6 by a movement to the left or right either to two different end faces 8, 8a two opposite side walls 9a, 9b of the furniture body 3 can be applied. Thus, the furniture drive 1 shown can be positioned on both left and right side walls 9a, 9b of a furniture body 3. In addition, the mounting stop 6, the two symmetrically arranged to the symmetry axis S stop surfaces 12, 12a. In Figure 2c, the stop surface 12 is applied to the end face 8.

FIG. 3 a shows a perspective view of the furniture drive 1, wherein the drive unit 4 has an assembly stop 6 movably mounted via a bolt 10 includes. In addition, the drive unit 4 has a mounting plate 7, which serves for fastening the drive unit 4 to a wall 9. Furthermore, a spring device 13 for applying force to the actuating part 5 is provided. FIG. 3b shows the area circled in FIG. 3a in an enlarged view. In this case, the two stop surfaces 12, 12a of the mounting stop 6 can be seen, these two stop surfaces 12, 12a for abutment against the end faces 8, 8a of two opposite side walls 9a, 9b serve. Furthermore, the axis A can be seen, around which the mounting stop 6 is pivotally mounted. The drive unit 4 has a recess 20 for receiving the mounting stop 6. The mounting stop 6 has a first web 18 and a second web 19. The width of the first web 18 is less than the width of the recess 20 and the width of the second web 19 corresponds approximately to the width of the recess 20. Therefore, a displacement of the mounting stop 6 along the bolt 10 and along the axis A in the direction R only after an at least partially completed pivoting movement of the mounting stop 6 relative to the drive unit 4 possible. The adjusting part 5 (not visible in this figure) is mounted pivotably relative to the drive unit 4 about the axis of rotation D, wherein the axis of rotation D and the axis A are substantially parallel to each other. Also, the direction R, in which the mounting stop 6 is displaceable, is parallel spaced from the axis of rotation D.

FIG. 4a shows the furniture drive 1 in a perspective view. In contrast to Figure 3a, the mounting stop 6 is shown in a pivoted position. In addition, the mounting plate 7 can be seen, which is suitable for attachment of the drive unit 4 to a wall 9 by means of screws or dowels (not shown).

FIG. 4b shows a detailed representation of FIG. 4a. With regard to the axis of rotation D of the actuating part 5 and the direction R, reference is made to the description of Figure 3b. In addition, the recess 1 1 of the drive unit 4 can be seen, in which the mounting stop 6 in its first position according to Figure 3a is at least partially receivable. FIG. 5a shows the furniture drive 1 according to FIG. 4a with a further position of the assembly stop 6, which in addition to the pivoted position of FIG. 4a is still displaced along the bolt 10 to the left. FIG. 5b shows the circled area of FIG. 5a in another perspective view. So that the mounting stop 6 is held in the second position in a predetermined position, the mounting stop 6 has a flattened portion 21. Another flattened region 21 is also formed symmetrically to the symmetry axis S on the other side. As a result, the mounting stop 6 is also held in the position displaced along the bolt 10 to the right in a predetermined position. The mounting stop 6 does not fall in the left or to the right shifted position so by its own weight down. The information "above" and "below" respectively refer to the usual mounting position of the furniture drive 1.

FIG. 5c shows the detail area according to FIG. 5b in a further perspective view. In this case, the recess 1 1 can be seen, which is provided for at least partially receiving the mounting stop 6 in its first position. Figure 6a shows a sectional view of the mounting stop 6 along the axis of symmetry S of the mounting stop 6. The mounting stop 6 is mounted on the pin 10 movable relative to the drive unit 4 and is located in this figure in the first position. In addition, the axis A is visible, about which the mounting stop 6 is pivotally mounted and along this axis A is displaceable.

Figure 6b shows the mounting stop 6 in contrast to Figure 6a in a pivoted about the pin 10 position. Figure 6c and Figure 6d show the mounting stop 6 in a displaced along the bolt 10 position. This position corresponds to the second position of the mounting stop 6. Furthermore, this position corresponds to the mounting state of the furniture drive 1, the drive unit 4 of the furniture drive 1 in this position both in terms of height and depth on or in the furniture body is positionable. It can also be seen from these two figures that the flattened region 21 of the assembly stop 6 shown in FIG. 5b at least partially abuts the drive unit 4 in the second position and thus prevents the assembly stop 6 from falling down due to its own weight.

The inventive method for mounting the furniture drive 1 will be described with reference to Figures 1 b, 2a and 2b. The following steps are carried out:

Moving the drive unit 4 into a position until the assembly stop 6 abuts against the end face 8 of the wall 9 of the furniture carcass 3, so that the drive unit 4 is positioned at depth in a predetermined mounting position in the furniture carcass 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).

Before moving the drive unit 4, the following step can be provided:

- Pivoting and / or moving the mounting stop 6 relative to the drive unit 4 in a second position in which the mounting stop 6 projects transversely from the drive unit 4, so that the mounting stop 6 can be applied to an end face 8 of the furniture body 3.

Furthermore, the following step may be provided before or after the fastening of the drive unit 4:

- Pivoting and / or moving the mounting stop 6 relative to the drive unit 4 in a first position in which the mounting stop 6 is at least partially received in a recess 1 1 of the furniture drive 1.

The following step can be carried out before the drive unit is attached:

- Move the drive unit 4 in a position until at least one of the mounting stop 6 separate stops 6a of the drive unit 4 on the bottom 14 of the top wall 15 of the furniture carcase 3 strike, so that the Drive unit 4 is positioned in terms of height at a predetermined mounting position in the furniture body 3.

At this point, it should be noted that it is not absolutely necessary to perform the movement of the height-positioning positioning drive unit 4 before moving the depth-positioning drive unit 4. This can also be done in reverse order.

In order to facilitate the movement of the drive unit 4, the drive unit 4 may rest against the wall 9 of the furniture body 3 during positioning for movement and be displaced along this wall 9.
