• wenigstens eine Anzeigevorrichtung, mit welcher eine mittels der wenigstens einen Einstellvorrichtung vornehmbare Krafteinstellung anzeigbar ist.

Des Weiteren betrifft die Erfindung ein Möbel mit einem Möbelkorpus und wenigstens einem relativ zum Möbelkorpus bewegbar gelagerten Möbelteil, vorzugsweise wenigstens einer in einer Gebrauchslage des Möbels um eine horizontale Achse relativ zum Möbelkorpus verschwenkbaren Möbelklappe.The invention relates to a furniture drive for moving a furniture part that is mounted so as to be movable relative to a furniture body, in particular a furniture flap that 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 which is mounted so as to be movable relative to the housing and 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 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 so as to be movable relative to the furniture body, preferably at least one furniture flap which can be pivoted about a horizontal axis relative to the furniture body in a position of use of the furniture.

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

A disadvantage of the state of the art is that an installer and/or operator of the furniture drive cannot generate any information about a force setting when using the furniture drive within the furniture panel of the furniture body. Furthermore, the installer and/or operator of the furniture drive is not able to determine or read the changed force setting when the force setting is changed. Adjustment of the force setting cannot therefore be ensured to a sufficient extent, which results in reduced comfort when operating the furniture drive and/or the furniture. Precise adjustment of the force setting is therefore not guaranteed when the furniture drive is installed in the furniture. However, an exposed furniture drive located outside the furniture panel reduces the storage space of the furniture on the one hand and impairs the aesthetic appearance of the furniture body on the other.

The objective technical task of the present invention is therefore to provide a furniture drive which 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 are characterized in particular by a precisely determinable force setting of the at least one Actuating arm in an installation position of the furniture drive in the furniture.

This object is solved by the features of claim 1.

It is therefore provided according to the invention that the at least one display device is designed separately from the at least one adjustment device and can be read in an installation position of the furniture drive in which the housing is arranged completely in the furniture panel of the furniture body except for the front side.

This enables an operator and/or fitter to precisely adjust the force setting in the installation position of the furniture drive, whereby no disassembly and reassembly of the furniture drive is necessary, since the force setting can be seen from a view from the front onto the furniture body via the at least one display device.

As stated at the outset, protection is also sought for a piece of furniture with a furniture body and at least one furniture part mounted so as to be movable relative to the furniture body, preferably at least one furniture flap pivotable about a horizontal axis relative to the furniture body in a position of use of the furniture, wherein the piece of furniture has at least one furniture drive according to one of the preceding claims, wherein the furniture body has at least one, preferably vertically arranged, furniture plate and the housing of the at least one furniture drive is arranged on or in the furniture plate, and wherein the at least one furniture part is to which at least one actuating arm of at least one furniture drive is attached or can be attached.

The term "separate" is to be interpreted in such a way that a separate component or component group display device can be identified, which may be spatially connected to the adjustment device directly or indirectly (such as by a material bond), but the display device functionally serves to visualize or read the force setting achieved by the adjustment device and thus has no functional interaction with the force setting itself.

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

According to an advantageous embodiment of the invention, it is provided that the at least one display device can be read in the installation position of the furniture drive at least in the relative position in which the at least one actuating arm protrudes through the front side of the housing.

This makes it possible for the setting of the force exerted by the at least one spring device on the at least one actuating arm in the at least one relative position of the at least one actuating arm to be easily read off the front side of the housing. This is of crucial importance for user-friendly adjustment of the force setting.

Advantageously, it is provided that the at least one display device is arranged at least partially on a region of the at least one actuating arm, preferably within the at least one actuating arm, which is arranged outside the housing in the relative position in which the at least one actuating arm protrudes through the front side of the housing.

The marking can, for example, be glued on, engraved, painted on and/or provided by elevations on a part of the furniture drive.

It has proven to be advantageous that the at least one pointer is designed in the form of a, preferably stamped, sheet metal or a wire, preferably with a thickening.

If the pointer is made of sheet metal, a particularly narrow furniture drive can be provided, whereby a rigid pointer enables a particularly precise display of the force setting. If the pointer is made of wire is designed, a display of the force setting can be generated particularly favorably over long distances, complex geometries and/or in hard-to-reach positions of the furniture drive, whereby the weight of the furniture drive can be kept low.

The material of the at least one pointer is generally arbitrary. The pointer is particularly preferably made of metal or plastic.

Furthermore, it is preferably provided that the at least one pointer is essentially translationally movable or rotatable.

According to an advantageous embodiment of the invention, it is provided that the at least one adjustment device comprises an adjusting device, preferably in the form of a tool holder, wherein the setting of the force exerted by the at least one spring device on the at least one actuating arm can be adjusted via the adjusting device.

Fig.1 shows a piece of furniture 26 with a furniture body 2, wherein the furniture 26 has a furniture drive 1. The furniture body 2 has a vertically arranged furniture plate 5 and the housing 4 of the furniture drive 1 is arranged in the furniture plate 5. In general, the furniture drive 1 can also be arranged on the furniture plate 5.

A movable furniture part 3 is indicated in dashed lines for reasons of clarity and does not appear in the following figures; however, it is generally arranged on the furniture drive 1. The furniture part 3 is attached to the actuating arm 6 of the furniture drive 1 via fastening means. The furniture part 3 is mounted movably relative to the furniture body 2 and is designed as a furniture flap that can be pivoted about a horizontal axis 30 relative to the furniture body 2 in a position of use 27 of the 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 front side 7.

The number of furniture drives 1, the position in the furniture panel 5 as well as 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 off when looking essentially from the front onto the furniture 26 or essentially normal onto the front side 7. A pointer 18 of the display device 11 is in a relative position 28a. In the Fig. 5a to Fig. 16 The components of the furniture drive 1 are explained in more detail.

The display device 11 is designed separately from the adjustment 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 front side 7.

Fig.2 differs from Fig.1 only in the sense that the pointer 18 of the display device 11 is in a changed relative position 28b. In the relative position 28b, the setting of the force exerted by the spring device 9 on the actuating arm 6 is lower than in Fig.1 (Relative position 28a), since the pointer 18 is displaced relative to a scale 17 further in the direction of the front surface 7.

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

Fig.3 differs from Fig.2 only in the sense that a viewing angle of the furniture panel 5 is achieved from the opposite side of the furniture panel 5. The display device 11 can be read from both sides at an oblique viewing angle relative to a vertical on the front surface 7.

Fig.4 differs from Fig.3 only in that the pointer 18 is again positioned in the first relative position 28a relative to the scale 17.

Fig. 5a shows a furniture drive 1 for moving the furniture part 3 which is movably mounted relative to the furniture body 2, comprising the housing 4, which can be arranged on or in the furniture panel 5 of the furniture body 2, and an actuating arm 6 which is movably mounted relative to the housing 4 and to which the movable furniture part 3 can be fastened.

The housing 4 has a front side 7 through which the actuating arm 6 protrudes in a plurality of relative positions 8. The furniture drive 1 has a spring device 9 with which a force can be exerted on the actuating arm 6, an adjusting device 10 for adjusting the force that can be exerted by the spring device 9 on the at least one actuating arm 6 and the display device 11, with which a force setting that can be made by means of the setting device 10 is displayed. The spring device 9 has spiral springs, which are shown in abbreviated form in order to recognize the spring holders on which the spiral springs are arranged. In general, however, the spiral springs extend completely over a longitudinal extension of the spring holders.

In general, however, the spring device 9 can also comprise other energy storage devices such as fluid energy storage devices and is not limited to the use of spiral springs. A damper device 32 for damping a movement of the actuating arm 6 is arranged above the spring device 9.

The display device 11 can be read in the installation position 12 of the furniture drive 1 at least in the relative position 8 in which the actuating arm 6 protrudes through the front side 7 of the housing 4.

Fig. 5b shows a pointer 18, wherein a scale 17 is arranged on the pointer 18, which can be moved relative to the housing 4, and the pointer 18 is moved relative to markings 21 on a film when a force is set via the setting device 10. The display device 11 is in a relative position 28b with a low set force of the spring device 9 on the actuating arm 6. The markings 21 can generally also be engraved into the housing 4, painted on or formed by elevations and/or depressions in the housing 4.

The pointer 18 is movable relative to the markings 21 when adjusting the force that can be exerted by the spring device 9 on the actuating arm 6. The setting of the force that can be exerted by the spring device 9 on the actuating arm 6 can be read by a relative position 28b of the markings 21 to the pointer 18.

Fig. 6a differs from Fig. 5a only in the sense that the pointer 18 in the form of a punched sheet 18a is arranged in a further relative position 28a relative to the scale 17, whereby an increased force setting can be determined by an operator and/or fitter of the furniture drive 1 when looking essentially normally at the front face 7 or slightly obliquely at the front face 7, in particular in the installation position.

Fig. 6b differs from Fig. 6a only in the sense that an inverted kinematics is shown, whereby the second relative position 28b has an identical point of application of the spring device 9 on a lever mechanism which is connected to the actuating arm 6, compared to Fig. 6a displays.

Fig. 7a and Fig. 7b show the furniture drive 1 with a complete housing 4, with which an installation of the furniture drives 1 in the installation position 12 in the furniture 26 is particularly preferred.

An opening 14 is arranged in the front side 7 of the housing 4 and the display device 11 is partially arranged inside the housing 4, since the pointer 18 in the form of a sheet 18a is arranged completely inside the housing 4 and two scales 17 have been attached to the housing 4 from the outside via a film 19 each. The display device 11 can be read by looking through the opening 14 into the interior of the housing 4. The display device 11 can generally also be arranged completely inside the housing 4.

The housing 4 has two side surfaces 15 spaced apart from one another, which are arranged parallel to one another and each transverse to the front side 7 of the housing 4. The display device 11 is arranged in regions between the two side surfaces 15. In general, the display device 11 can also be arranged completely between or in a clear width 16 of the side surfaces 15.

The display device 11 is partially arranged on the adjustment device 10, wherein the display device 11 is arranged on a side of the adjustment device 10 facing the front side 7 and between the front side 7 and the at least one adjustment device 10.

In Fig. 7a the film 19 is not transparent and is secured to the housing 4 by fastening means. In Fig. 7b the scales 17 are glued onto transparent plastic films 19 on both side surfaces 15 of the housing 4 in areas above both housing openings 20 from the outside. The scales 17 are arranged on a side of the film 19 facing the setting device 10. Particularly Preferably, the plastic film 19 is glued to at least one of the side surfaces 15 from the outside, wherein the scale 17 is arranged on the adhesive side of the film 19.

Fig. 7c shows a display device 11, wherein the scale 17 is arranged on one of the two side surfaces 15 and the second housing opening 20 is not covered at least in part by a film 19. The scale 17 is arranged on an adhesive side of the film 19, wherein that region of the film on which the scale 17 is arranged is free of adhesive.
