EP3786405B1 - Furniture drive for moving a movable furniture part - Google Patents

Description

• eine Antriebseinheit zur Montage am oder im Möbelkorpus,
• zumindest einen bewegbar gelagerten Stellteil zum Bewegen des bewegbaren Möbelteiles.

The present invention relates to a furniture drive for moving a movably mounted furniture part relative to a furniture body, comprising:

• a drive unit for mounting on or in the furniture body,
• at least one movably mounted control part for moving the movable furniture part.

The invention also relates to a piece of furniture with at least one such furniture drive. Finally, the invention relates to a method for installing a furniture drive on or in a furniture body.

Furniture drives that are positioned on or in a furniture body with the help of a "ruler and pencil" are already known. A disadvantage of the known positioning measure, however, is that such a positioning is only possible very imprecisely and with a great deal of effort. A correct assembly position is a necessary prerequisite so that the furniture part can be moved properly in the assembled state.

The DE 20 2013 007 519 U1 shows, for example, a mounting plate which is designed for fastening two or more actuators with housings of different types.

The WO 2009/152537 A2 shows a furniture drive with an ejector for ejecting a movable furniture part from its closed position in or on a furniture body.

The object of the invention is to avoid at least one of the disadvantages described above and to specify a furniture drive that is improved compared to the prior art and an improved piece of furniture with at least one furniture drive, so that the furniture drive can be installed more easily on or in a furniture body.

A further object of the invention is to specify an improved method for installing a furniture drive on or in a furniture carcass, in order in turn to ensure simplified, in particular standardized, installation.

These objects are solved by the features of independent claims 1, 10 and 11.

Advantageous embodiments of the invention are defined in the dependent claims.

An essential idea with regard to the furniture drive according to the invention is that at least one assembly stop that can be placed on the furniture body is provided on the drive unit. This measure allows the furniture drive to be positioned at a predetermined installation position on or in a furniture body.

In other words, it can be provided that the furniture drive has at least one assembly stop that can be placed on an end face of the furniture body, wherein the drive unit can be positioned at a predetermined assembly position on or in the furniture body by the assembly stop resting on the end face of the furniture body. The furniture body can have at least one vertically running side wall, with the end face of the furniture body preferably being formed by a vertically running narrow side of this side wall. As an alternative to this, it can be provided that the end face is formed by a horizontally running narrow side of a top wall of the furniture body.

According to the invention it is further provided that the assembly stop is mounted so that it can move to a limited extent between a first position and a second position, the assembly stop being at least partially received in a recess of the furniture drive in the first position and in the second position projects transversely from the drive unit, so that the assembly stop can be placed against an end face of the furniture body.

According to one exemplary embodiment, it is provided that the drive unit has a housing and/or a mounting plate and that the mounting stop is designed as a component that is separate from the housing and/or from the mounting plate. This means that a damaged assembly stop can be easily replaced.

The assembly stop can be movably mounted relative to the drive unit. Provision is preferably made for the assembly stop to be mounted such that it can pivot and/or slide relative to the drive unit between a first position and a second position.

According to a further exemplary embodiment, it is provided that the assembly stop is preassembled on the drive unit, the assembly stop being mounted on this drive unit so that it can pivot and/or slide relative to the drive unit in the preassembled state.

According to a further exemplary embodiment, a cover cap can be provided, with the cover cap at least partially covering the assembly stop in the first position and/or a lateral viewing area of the furniture drive in the assembled state. The cover cap may preferably have an arcuate portion adapted to cover the assembly stop in its first position.

In a piece of furniture with at least one furniture drive, it can be provided that the furniture has a furniture body and a furniture part - preferably a flap - that can be moved up relative to the furniture body, the furniture part being movably mounted by the furniture drive between a closed position and a position raised relative to the furniture body. So it is the movement of the furniture part relative to the furniture body by the furniture drive, for example supported by a spring device and/or by an electric drive.

For the sake of simplicity, reference is made in the following to a "mounting plate" instead of the "housing and/or mounting plate" of the drive unit, but the same explanations apply to the housing.

the assembly stop in different positions.

Figure 1a shows a piece of furniture 16 which has a furniture body 3 and a furniture part 2 which can be moved up relative to the furniture body 3 . The furniture part 2 that can be moved up is designed as a furniture flap in this figure. Furthermore, a furniture drive 1 is arranged on each of the two side walls 9a, 9b, the furniture drives 1 each having a drive unit 4 and at least one movably mounted control part 5 . The furniture part 2 is through the Control parts 5 can be moved between a closed position and a position that is raised relative to the furniture body 3 . Furniture part 2 is in figure 1 shown in a raised position. The control parts 5 can also have a multi-part structure. The furniture drive 1 arranged on the side wall 9b has, for example, three actuating arms 5a, 5b, 5c which are connected to one another in an articulated manner. In this context, it is also pointed out that the control parts 5 do not have to be connected directly to the furniture part 2 . An indirect connection via further levers and/or fittings can also be provided.

Figure 1b shows a wall 9 and a section of a top wall 15 of a furniture body 3. The furniture drive 1 is not yet positioned at a predetermined assembly position. Furthermore, the furniture drive 1 has a drive unit 4, a movably mounted control part 5, a substantially T-shaped assembly stop 6 and two stops 6a. The assembly stop 6 is movably mounted relative to the drive unit 4 . The two stops 6a serve to position the drive unit 4 in the furniture body 3 in terms of height.

Figure 2a shows a wall 9 and a section of a top wall 15 of a furniture body 3. The top wall 15 has an underside 14, the two stops 6a being able to be placed on this underside 14. The furniture drive 1 again has a drive unit 4, an actuating part 5 which is pivotably mounted relative to the drive unit 4, an assembly stop 6 and the two aforementioned stops 6a. The substantially T-shaped mounting stop 6 is used to rest against the end face 8 of the wall 9. In contrast to Figure 1b If the stop 6a shown on the left is already applied to the underside 14 of the top wall 15 and the drive unit 4 is thus pre-positioned in terms of height in the furniture body 3, the stop 6a 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 section of the top wall 15 of the furniture body 3. The furniture drive 1 shown is now positioned at a predetermined mounting position on the wall 9 in the furniture body 3. The two stops 6a, which serve to position the drive unit 4 in terms of height, rest on 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 in the furniture body 3 in terms of depth. By resting a flat side of the drive unit 4 on the wall 9, the drive unit 4 is thus fixed in all directions in the furniture body 3 at a predetermined mounting position. In contrast to Figure 2a the assembly stop 6 is shown in a pivoted and shifted position, so that the assembly stop 6 can be applied to the end face 8 . As an alternative to this, it is also possible to place the drive unit 4 with a flat side on the underside 14 of the top wall 15 so that the assembly stop 6 can be placed on the end face 17 of the top wall 15 .

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

Figure 3a shows a perspective view of the furniture drive 1 , the drive unit 4 comprising a mounting stop 6 which is movably mounted via a bolt 10 . In addition, the drive unit 4 has a Mounting plate 7, which is used to attach the drive unit 4 to a wall 9. Furthermore, a spring device 13 for applying force to the actuating part 5 is provided.

Figure 3b shows the in Figure 3a circled area in an enlarged view. The two stop surfaces 12, 12a of the assembly stop 6 can be seen, these two stop surfaces 12, 12a serving to rest against the end faces 8, 8a of two opposite side walls 9a, 9b. Furthermore, the axis A can be seen, about which the assembly stop 6 is pivotably mounted. The drive unit 4 has a recess 20 for receiving the assembly stop 6 . The assembly 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 assembly stop 6 along the bolt 10 or along the axis A in direction R is only after an at least partial pivoting movement of the assembly stop 6 relative to the drive unit 4 is possible. The control part 5 (not visible in this figure) is mounted so that it can pivot about the axis of rotation D relative to the drive unit 4, with the axis of rotation D and the axis A running essentially parallel to one another. The direction R, in which the assembly stop 6 can be displaced, also runs parallel at a distance from the axis of rotation D.

Figure 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 fastening the drive unit 4 to a wall 9 using screws or dowels (not shown).

Figure 4b shows a detailed representation of the Figure 4a . Regarding the axis of rotation D of the control part 5 and the direction R is on the description of Figure 3b referred. In addition, the recess 11 of the drive unit 4 can be seen in which according to the assembly stop 6 in its first position Figure 3a is at least partially recordable.

Figure 5a shows the furniture drive 1 according to FIG Figure 4a with a further position of the mounting stop 6, which in addition to the pivoted position of Figure 4a is still shifted along the bolt 10 to the left.

Figure 5b shows the circled area of the Figure 5a in another perspective view. So that the assembly stop 6 is held in a predetermined position in the second position, the assembly stop 6 has a flattened area 21 . Another flattened area 21 is also formed symmetrically to the axis of symmetry S on the other side. As a result, the assembly stop 6 is also held in a predetermined position in the position displaced to the right along the bolt 10 . In the position shifted to the left or to the right, the assembly stop 6 does not fall down under its own weight. The information "top" or "bottom" refers to the usual mounting position of the furniture drive 1.

Figure 5c shows the details pane according to Figure 5b in another perspective view. Here, the recess 11 can be seen, which is provided for at least partially accommodating the assembly 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 movably via the bolt 10 relative to the drive unit 4 and is in the first position in this figure. In addition, the axis A can be seen, about which the assembly stop 6 is pivotably mounted and along this axis A is displaceable.

Figure 6b shows the assembly stop 6 in contrast to FIG Figure 6a in a pivoted position about the bolt 10.

Figure 6c and Figure 6d show the assembly stop 6 in a position displaced along the bolt 10 . This position corresponds to the second position of the assembly stop 6. This position also corresponds to the assembled state of the furniture drive 1, with the drive unit 4 of the furniture drive 1 being positionable in this position both in terms of height and depth on or in the furniture body. Based on these two figures, it can also be seen that the Figure 5b The illustrated flattened area 21 of the assembly stop 6 in the second position rests against the drive unit 4 at least in some areas, thus preventing the assembly stop 6 from falling down due to its own weight.

• Bewegen der Antriebseinheit 4 in eine Stellung, bis der Montageanschlag 6 an der Stirnseite 8 der Wand 9 des Möbelkorpus 3 anschlägt, sodass die Antriebseinheit 4 tiefenmäßig an einer vorgegebenen Montageposition im Möbelkorpus 3 positioniert wird,
• Befestigen der Antriebseinheit 4 an der vorgegebenen Montageposition im Möbelkorpus 3, vorzugsweise mittels Schrauben oder Dübeln (nicht dargestellt),
• Verschwenken und/oder Verschieben des Montageanschlages 6 relativ zur Antriebseinheit 4 in eine erste Stellung, in welcher der Montageanschlag 6 in einer Ausnehmung 11 des Möbelantriebes 1 zumindest teilweise aufgenommen wird.

The inventive method for assembling the furniture drive 1 is based on the figures 1b , 2a and 2b described. The following steps are carried out:

• Move the drive unit 4 into a position until the assembly stop 6 strikes the end face 8 of the wall 9 of the furniture body 3, so that the drive unit 4 is positioned at a predetermined assembly position in the furniture body 3 in terms of depth,
• Fastening the drive unit 4 at the specified mounting position in the furniture body 3, preferably by means of screws or dowels (not shown),
• Pivoting and/or shifting of the mounting stop 6 relative to the drive unit 4 into a first position in which the mounting stop 6 is at least partially accommodated in a recess 11 of the furniture drive 1 .

• Verschwenken und/oder Verschieben des Montageanschlages 6 relativ zur Antriebseinheit 4 in eine zweite Stellung, in welcher der Montageanschlag 6 quer von der Antriebseinheit 4 absteht, sodass der Montageanschlag 6 an eine Stirnseite 8 des Möbelkorpus 3 anlegbar ist.

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 protrudes transversely from the drive unit 4 so that the mounting stop 6 can be placed against an end face 8 of the furniture body 3 .

• Bewegen der Antriebseinheit 4 in eine Stellung, bis wenigstens einer der vom Montageanschlag 6 gesonderten Anschläge 6a der Antriebseinheit 4 an der Unterseite 14 der Deckwand 15 des Möbelkorpus 3 anschlagen, sodass die Antriebseinheit 4 höhenmäßig an einer vorgegebenen Montageposition im Möbelkorpus 3 positioniert wird.

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

• Move the drive unit 4 into a position until at least one of the stops 6a of the drive unit 4, which is separate from the assembly stop 6, strikes the underside 14 of the top wall 15 of the furniture body 3, so that the drive unit 4 is positioned at a predetermined installation position in the furniture body 3 in terms of height.

At this point it is pointed out that it is not absolutely necessary to move the drive unit 4 for vertical positioning before moving the drive unit 4 for vertical positioning. This can also be done in reverse order.

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