Description

Furniture drive for moving a furniture part that is mounted so as to be movable relative to a furniture body

The invention relates to a furniture drive for moving a furniture part mounted so as to be movable relative to a furniture body, in particular a furniture flap which can be pivoted about a horizontal axis relative to the furniture body, comprising:

- A housing which can be arranged on or in a furniture panel of the furniture body,

- At least one actuating arm mounted movably relative to the housing, to which the movable furniture part can be fastened, the housing having an end face through which the at least one actuating arm protrudes in at least one relative position,

- At least one spring device with which a force can be exerted on the at least one actuating arm,

- At least one adjusting device for adjusting the force which can be exerted by the at least one spring device on the at least one actuating arm, and

- At least one display device with which a force setting that can be made by means of the at least one setting device can be displayed.

Furthermore, the invention relates to a piece of furniture with a furniture body and at least one furniture part mounted movably relative to the furniture body, preferably at least one furniture flap that can be pivoted about a horizontal axis relative to the furniture body in a position of use of the piece of furniture.

Such a furniture drive is already known from DE 20 2010 005 934 U1, in which a force setting of an actuating arm can be read off via an opening in a housing. The opening is arranged on a side surface of the housing. The force setting can be manipulated via an adjustment device. The furniture drive is arranged on an inside of a furniture panel of a furniture body of a piece of furniture.

The disadvantage of the prior art is that a fitter and / or operator of the furniture drive when using the furniture drive within the furniture panel of the Furniture carcass cannot generate any information about a force setting. Furthermore, when the force setting is changed, the fitter and / or operator of the furniture drive is not able to determine or read off the changed force setting. Adjustment of the force setting cannot be guaranteed to a sufficient extent, which results in reduced convenience in operating the furniture drive and / or the furniture. A precise setting of the force setting is not guaranteed when the furniture drive is installed in the furniture. A furniture drive that is exposed outside of the furniture panel, however, on the one hand reduces storage space in the furniture and on the other hand adversely affects the aesthetic appearance of the furniture body.

The objectively technical object of the present invention is therefore to provide a furniture drive that is improved compared to the prior art and a piece of furniture with at least one such furniture drive, in which the disadvantages of the prior art are at least partially eliminated and which in particular can be precisely determined Characterize the force setting of the at least one actuating arm in an installation position of the furniture drive in the furniture.

The furniture body 2 has a vertically arranged furniture panel 5 and the housing 4 of the furniture drive 1 is arranged in the furniture panel 5. In general, the furniture drive 1 can also be arranged on the furniture panel 5.

A movable furniture part 3 is indicated in dashed lines for reasons of clarity and does not appear in the following figures; is, however, generally arranged on the furniture drive 1. The furniture part 3 is fastened to the actuating arm 6 of the furniture drive 1 via fastening means. The furniture part 3 is mounted so as to be movable relative to the furniture body 2 and is designed as a furniture flap which can be pivoted about a horizontal axis 30 relative to the furniture body 2 in a position of use 27 of the piece of furniture 26.

The furniture part 3 can be moved relative to the furniture body 2 by the furniture drive 1. The housing 4 of the furniture drive 1 is arranged completely in the furniture panel 5 of the furniture body 2 except for the end face 7.

The number of furniture drives 1, the position in the furniture panel 5 and the number and / or orientation of the furniture panels 5 on which the furniture drives 1 are arranged is generally arbitrary. In the detail section, a display device 11 can be seen, which enables a force setting of the force exerted by a spring device 9 on an actuating arm 6 to be read, looking essentially from the front onto the piece of furniture 26 or essentially normally onto the end face 7. A pointer 18 of the display device 11 is in a relative position 28a. The components of the furniture drive 1 are explained in more detail in FIGS. 5 a to 16.

The display device 11 is designed separately from the setting device 10 and can be read in an installation position 12 of the furniture drive 1 in which the housing 4 is arranged completely in the furniture panel 5 of the furniture body 2 except for the end face 7.

FIG. 2 differs from FIG. 1 only in that the pointer 18 of the display device 11 is in a changed relative position 28b. In the relative position 28b, a setting of the force exerted by the spring device 9 on the actuating arm 6 is selected to be lower than in FIG.

In general, however, that relative position 28b in which the pointer 18 is located closer to the end face 7 can also indicate an increased force setting. This fact can be taken into account by an inverted scale 17. The relative positions 28a, 28b are not restrictive for the display device 11, any number of relative positions 28a, 28b being possible, each with different force settings.

FIG. 3 differs from FIG. 2 only in that an angle of view of the furniture panel 5 is obtained from the opposite side of the furniture panel 5. The display device 11 can be read on both sides of the end face 7 at an oblique viewing angle relative to a vertical.

The pointer 18 is arranged relative to the scale 17 in such a way that the relative position 28b with a minimal application of force to the actuating arm 6 by the Spring device 9 is displayed.

10b differs from FIG. 10a only in that the display device 11 is in a changed relative position 28a, an operator of the furniture drive 1 being able to read an increased force setting of the actuating arm 6 by looking normally at the end face 7.

FIG. 11 differs from FIG. 9 only in that the display device 11 is in the relative position 28 a. Since the point of application of the spring device 9 on the structure, which is kinematically coupled to the actuating arm 6, is unchanged, there is, for example, a modified movable furniture part 3 with a reduced mass. An operator or fitter of the furniture drive 1 can thus estimate the amount of force with which the movable furniture part 3 can be moved with the aid of the furniture drive 1.

The spring device 9 has shortened spiral springs in the illustration in order to make the spring receptacles on which the spiral springs are arranged visible; However, the spiral springs generally extend over the entire longitudinal extent of the spring receptacles.

FIG. 12 differs from FIG. 11 only in that the force setting was manipulated via the setting device 10, a point of application of the spring device 9 being shifted downwards and the setting of the force setting via the setting device means that the display device 11 is in the relative position 28b , in order to indicate to the operator that the amount of force required to move the movable furniture part 3 has changed. The point of application of the spring device 9 on the lever mechanism of the actuating arm 6 can be adjusted via the setting device 10 and is coupled to the force setting and to the display via the display device. By changing the force setting via the setting device 10, a changed torque acts on the actuating arm 6, as a result of which the force acting on the movable furniture part 3 is changed.

A fastening device 31 for fastening the housing 4 in a recess of the furniture body 2 is arranged on the furniture drive 1.

The fastening device 31 comprises a rotatably mounted actuating element and two fastening elements which can be sunk into a wall of the recess and / or can be pressed onto the wall. A coupling device is provided in the fastening device 31, with which a rotary movement of the actuating element can be converted into a lowering movement and / or into a pressing movement of the two fastening elements. The actuating element and the two fastening elements are arranged on the same side of the housing 4 and spaced apart from one another in a longitudinal direction of the housing 4. The number of fastening elements is generally arbitrary.

The actuating arm opening 13 is arranged on both side surfaces of the actuating arm 6, whereby the force setting can be read on the display device 11 on both sides of the actuating arm 6 and can be used particularly favorably with furniture 26 in corners of a room.

The pointer 18 in the form of a wire 18b has a thickening 22 at a free end, the pointer being arranged in a first relative position 28a.

FIG. 14b differs from FIG. 14a only in that the actuating arm opening 13 is arranged on an underside of the actuating arm 6, wherein in FIG. 14a the actuating arm opening 13 extends continuously through both side surfaces of the actuating arm 6. In general, the actuating arm opening 13 can also be arranged on only one side surface or on both side surfaces and the underside of the actuating arm 6 in order to display the force setting for an operator via the display device 11.

In general, a further display device 11 can be provided, with pointer 18 and / or a scale 17 being arranged on the housing opening 20 on the setting device 10, for example.

FIG. 14c shows the detail section of the display device 11 in a further relative position 28b, the force setting being changed by means of the setting device 10 compared to the relative position 28a shown in FIG. 14a. Fig. 15a shows a furniture drive, the actuating arm opening 13 is arranged on an underside of the actuating arm 6, whereby the force setting via the

Display device 11 ensures particularly convenient reading of the force setting via display device 11 by an operator and / or fitter, particularly in the case of furniture drives 1 arranged high on a piece of furniture.

In general, however, an actuating arm opening 13 can also be arranged on an upper side of the actuating arm 6 in order to enable the force setting to be determined in a user-friendly manner, particularly in the case of furniture drives 1 located deep on the furniture 26.

In the enlarged detail it can be seen that the thickening 22 of the

Indicating device 11 by the relative position 28a, in which the pointer 18 is located closer to a plus sign, indicates an increased force acting on the actuating arm 6 by the spring device 9.

15b differs from the detail section of FIG. 15a only in that the pointer 18 is arranged in a further relative position 28b on the actuating arm opening 13 and an additional scale 17 is arranged on the underside of the actuating arm 6 to simplify the determination of the force setting.

The pointer 18 is in the form of a wire 18b with a thickening 22. In general, the wire 18b can comprise a Bowden cable, for example.

Fig. 16a shows a furniture drive 1 with the actuating arm 6 mounted about an axis of rotation for moving the movable furniture part 3, the spring device 9 - arranged on spring holders - for applying force to the actuating arm 6 and a transmission mechanism - in the form of a Flebelwerkes - for transmitting a force from the Spring device 9 on the actuating arm 6, the transmission mechanism being arranged on the spring device 9 via a point of application.

The point of application can be adjusted via an adjusting device 10 for setting the position of the point of application, with a changed torque acting on the actuating arm 6 for a changed point of application to move the movable furniture part 3 (not shown for reasons of clarity).
