    The present invention relates to a furniture drive with the features of the preamble of claim 1 and a piece of furniture according to the features of the preamble of claim 4.
    A generic furniture drive or a generic furniture, for example, from WO 2007/009133 A1 of the applicant out. This document has made it its mission to further develop a furniture drive so that the risk of unintentional triggering is reduced. This was solved in such a way that a threshold value for the triggering of the electric motor (triggering sensitivity) that was of different levels depending on the opening state of the movable furniture part was provided. In the closed end position of the movable furniture part, the threshold value was lower than the threshold value for the fully opened end position of the movable furniture part. This is based on the consideration that the movable furniture part is exposed in its closed end position hardly unintentional forces. In the fully open end position of the movable furniture part, however, it can lead to unintentional forces caused by the loading or unloading of the movable furniture part with contents. This is taken into account by the higher selected threshold value in this position of the movable furniture part.
    The object of the invention is to provide a generic furniture drive and a generic furniture, which represent an alternative solution while maintaining the concept discussed above.
    This object is achieved by a furniture drive with the features of claim 1 and a piece of furniture with the features of claim 4.
    Advantageous embodiments of the invention are defined in the dependent claims.
    The invention is based on the surprising realization that it is possible even when providing two identical sensors, each of which has the same triggering threshold, effectively to achieve a different triggering sensitivity, depending on whether the movable furniture part is in the closed end position or Not. This is inventively achieved in that the one (second) sensor is coupled independently of the transmission with a mechanical control sensor and can respond directly to an external force of a user on the movable Möbetteil. The force exerted by the user is preferably not directly on the mechanical control sensor, but indirectly on the movable furniture part. Since the 69367 36 / fr «* ·« φ · ** · · · · · «· · · · · · · · · · · · · · If a mechanical pressure sensor is arranged between the moving furniture part and the furniture body, pressing and / or pulling a user onto the movable furniture part will lead to a movement of the mechanical part Stellfühlers, which is detected directly by the corresponding (second) sensor.
    The first sensor, however, is mechanically coupled to the transmission. This results in a larger inertia, that is, in other words, the sensor takes longer to transmit a trigger signal to the switching device.
    Thus, if the movable furniture part is in the closed end position in or on the furniture carcass and a user exerts a pressure or pulling action on the movable furniture part, then both the movement of the mechanical steep sensor and thus a triggering of the second sensor as well as a Movement of the output and thus of the transmission and finally the coupled with the transmission first sensor. However, since the second sensor triggers faster than the first sensor because of its immediate triggering, a triggering sensitivity that substantially corresponds to the triggering sensitivity of the second sensor, which results from its design, is effectively obtained.
    The movable furniture part is not in its closed end position, that is, it was either only partially or completely moved in the direction of the open end position, the mechanical position sensor is no longer on the furniture body. If a user exerts a compressive or tensile force on the movable furniture part, only the first sensor can report this to the switching device, since the second sensor does not receive a signal from the mechanical position sensor. In this case, however, results in a trigger sensitivity, which is higher than in the closed end position, since the first sensor, which is not absolutely necessary - even if it is identical to the second sensor - detected only via the transmission, the train or pressure application of the user ,
    Alternatively or additionally, it is of course possible not to select the first and the second sensor identical, but to select a sensor for the first sensor which has a lower triggering sensitivity than the second sensor. To a certain extent, it would even be possible to choose as the second sensor such a sensor, which in itself has a lower trigger sensitivity than the first sensor, if this is overcompensated by the mechanical coupling of the first sensor with the transmission. % ··· «« t ** l # · ♦ · · ♦ ······················································································ « 9 9 9 9 9 • · 4 * ··· «« «·· 3
    The mechanical adjusting sensor may be formed, for example, as a displaceably mounted plunger or pivotally mounted lever, as is known per se. Particularly suitable is a pivotally mounted lever, such as, for example, the subject of WO 2010/081178 A1 of the applicant.
    Preferably, a control or regulating device is provided for the electric motor, and particularly preferably the switching device is formed in the control or regulating device. The invention makes it possible, however, not to have to provide any expensive control or regulation device and instead to provide only a simple switching device.
    Further advantages and details of the invention will become apparent from the figures and the associated description of the figures. Showing:
    1 is a schematic representation of a furniture drive according to the invention,
    Fig. 2 shows an inventive furniture with a Möbetantrieb invention in perspective view and
    Fig. 3 to 5 different views of the furniture drive according to the invention.
    1 shows in schematic form a furniture drive according to the invention 1. This has an electric motor 3, which drives a non-illustrated movable furniture part 11 (see, for example, Fig. 2) via an output shown here as a gear 2. Between the electric motor 3 and output 2, a transmission 4 is arranged or switched. Furthermore, a switching device 5 is provided for switching the electric motor 3. A first sensor 6 is mechanically coupled to the transmission 4 and supplies its signals to the switching device 5. A second sensor 7 is coupled to a mechanical adjusting sensor 8 and also supplies its signals to the switching device 5.
    2 shows a perspective view of an example of an inventive furniture 9 with a furniture body 10 and a movable furniture part 11, which is drivable by an inventive furniture drive 1. The movable furniture part 11 is shown in a position between the closed end position in the furniture body 10 and the fully open end position. Since it is in the present case a handle-less movable furniture part 11 (in the form of a drawer), a slight gap between the front panel of the movable furniture part 11 and the front side of the furniture body 10 is provided in a known manner in the closed end position of the movable furniture part 11 to one
    Provide triggering path for the triggering of the electric motor 3 by applying pressure to the furniture part 11.
    Fig. 3a shows the furniture drive 1 according to the invention in the installed position of Flg. 2, but for the sake of clarity, both the furniture body 10 and the movable furniture part 11 have been omitted. In this embodiment, a furniture drive 1 is fixedly connected to the movable furniture part 11. About the example shown in Fig. 5 output 2 in the form of a gear, the electric motor 3 can transmit power to the exemplary illustrated rack 13. This leads to a movement of the movable furniture part 11. In the illustrated embodiment, an inventive furniture drive 1 is provided only on one side of the movable furniture part 11. In order to enable a uniform application of force to the movable Möbetteil 11, a known synchronization rod 12 is provided, which allows a portion of the force of the electric motor 3 to a arranged on the other side of the movable furniture part 11 further gear. This meshes with another rack (not shown).
    Gear and rack are shown only as an example. It could be used a completely different output 2, for example in the form of a friction wheel or in the form of a cable.
    In Fig. 3a, the mechanical adjusting sensor 8 is clearly visible, which cooperates with a mounted on the furniture body 10 stop 14. Both a pressing of the mechanical adjusting sensor 8 to the stop 14 and a lifting of this lead to a movement of the mechanical adjusting sensor 8, which via a gear portion 15 (see, for example, Fig. 4a) on the drive wheel of a potentiometer (second sensor 7) transmitted can be.
    In contrast, the first sensor 6 (embodied here as a Hall sensor - see, for example, FIG. 5 b) is mechanically coupled to the transmission 4.
    The transmission 4 has the function to transmit the driving force of the electric motor 3 in a suitable translation to the output 2 or the synchronization rod 12. This is done after the screw 31 of the electric motor 3 via the gears 41,42, 43,44 and 45. The last gear 45 finally meshes with the output 2. The mechanical coupling of the first sensor 6 with the gear 4 takes place via the gear 43rd and the gears 62 and 61. • · * · ♦ ······································································ I »· · Μ 5
