The invention relates to an electromotive furniture drive for adjusting movable furniture parts (5, 6) of an item of functional furniture (1), having a control device (9), at least one adjusting drive (7, 8) with an electric motor, and at least one evaluation circuit (10) with an input (11, 12), which evaluation circuit can be electrically conductively connected to a sensor, which is attached to the item of functional furniture (1), and forms a proximity and/or contact detector together with said sensor. The electromotive furniture drive is distinguished in that at least two proximity and/or contact detectors are formed by in each case one sensor or a group of sensors together with the at least one evaluation circuit (10), it being possible for said proximity and/or contact detectors to be assigned to different moving furniture parts (5, 6) of the item of functional furniture (1). The invention further relates to an item of functional furniture (1) having at least two groups of movable furniture parts (5, 6) and an electromotive furniture drive of this kind.
An electromotive furniture drive for adjusting movable furniture parts of an item of functional furniture, said electromotive furniture drive comprising two adjustment drives including at least one electric motor, a control unit operably connected to the adjustment drives, and an analysis circuit configured for connection in an electrically conductive manner to a plurality of sensors attached to the item of functional furniture to thereby form at least two proximity and touch detectors associated with different ones of the movable furniture parts of the item of functional furniture, wherein a first sensor is configured as a first sensor line that directly contacts, a first movable furniture part in a conductive connection, and a second sensor is configured as a second sensor line with a planar electrode bonded to a second movable furniture part thereby forming a capacitive coupling to the second movable furniture part, wherein a capacitance change of the first movable furniture part due to proximity or touch to the first movable furniture part by a body part is transmitted by the first sensor line to the analysis circuit which detects the proximity or touch of the first movable furniture part by the body part and a capacitance change of the second movable furniture part due to proximity or touch to the second movable furniture part b a body part is transmitted by the second sensor line to the analysis circuit which detects the proximity or touch of the second movable furniture part by the body part and the analysis circuit generates a signal to stop at least one of the two the adjustment drives, wherein after stopping, at least one of the two adjustment drives is operated for a predefined period of time in a reverse movement direction to release a body part which may have been pinched, wherein the analysis circuit includes a plurality of inputs coupled to the sensors in one-to-one correspondence and a multiplexer configured to sequentially connect the inputs to a single detector circuit of the analysis circuit.

This application is the U.S. National Stage of International Application No. PCT/EP2015/069631, filed Aug. 27, 2015, which designated the United States and has been published as International Publication No. WO 2016/030458 and which claims the priority of German Patent Application, Serial No. 20 2014 104 011.0, filed Aug. 27, 2014, pursuant to 35 U.S.C. 119(a)-(d).
The invention relates to an electromotive furniture drive for adjusting movable furniture parts of an item of functional furniture, having a control unit, at least one adjustment drive having an electric motor, and at least one analysis circuit having an input, which is connectable in an electrically conductive manner together with a sensor attached to the item of functional furniture, and forms a proximity and/or touch detector. The invention additionally relates to an item of functional furniture having such an electromotive furniture drive.
Such electromotive furniture drives are known and comprise, for example, a number of adjustment drives, for example, linear drives. A linear drive generates a linear movement at an output element and has at least one electric motor, a gear train, and the output element, wherein the gear train having the output element is connected downstream of the electric motor. The linear drive and its output element are connected to furniture components and move or adjust them in relation to one another during operation of the motors. The furniture components are, for example, movably connected to a base frame and/or to one another by so-called functional or movement fittings. These fittings are typically made of metallic materials, for example, steel.
The invention will be explained in greater detail hereafter on the basis of an exemplary embodiment with the aid of figures. In the figures:
FIG. 1 shows a schematic perspective view of an exemplary furniture arrangement; and
FIG. 2 shows a block diagram of components of the furniture arrangement.
FIG. 1 shows an exemplary furniture arrangement having an item of functional furniture 1. A bed is shown by way of example as the item of functional furniture 1 here. The item of functional furniture 1 has a base element 2, a frame-type framework having feet here. A slatted frame having a functional fitting 3 is inserted into the base element 2. The slatted frame supports a mattress M.
In the illustrated example, the item of functional furniture 1 has two movable furniture parts 5 and 6, which are movable in relation to a fixed base part 4 arranged between them. Specifically, the two movable furniture parts 5, 6 are a back part and a leg part. They are also referred to as back part 5 and leg part 6 hereafter for simpler description.
The movable arrangement of the movable furniture parts 5 and 6 is implemented by the functional fitting 3, also called a movement fitting. The movement is designed as displaceable and/or pivotable.
