Abstract

An electromotive furniture drive for adjusting at least one movable component of a piece of furniture, has at least one electric motor for adjusting the movable component, at least one operating device with switching elements for actuating the electric motor, at least one control unit for controlling the at least one electric motor as a function of the operating device, and at least one power supply unit. At least one analyzing device has at least one actuating element for checking the function of the at least one electric motor, the at least one control unit, the at least one operating device and of the at least one power supply unit, and has at least one signaling element.

Claims (24)

1. An electromotive furniture drive for adjusting at least one movable component of a piece of furniture, the drive comprising;

at least one electric motor configured to adjust the movable component,

at least one operating device with switching elements configured to actuate the at least one electric motor,

at least one control unit for controlling the at least one electric motor as a function of the at least one operating device,

at least one power supply unit for the electric supply of the control unit,

at least one analyzing device including at least one actuating element and at least one signaling element, the at least one actuating element being configured to check functionality of each of the at least one electric motor, the at least one control unit, the at least one operating device and the at least one power supply unit.

2. The electromotive furniture drive of claim 1 , wherein the at least one actuating element of the at least one analyzing device is configured to perform the same function as the at least one switching element of the at least one operating device.

3. The electromotive furniture drive of claim 2 , wherein the at least one control unit includes a plurality of power switching elements configured to switch a power path of the at least one electric motor, and wherein the at least one actuating element of the at least one analyzing device is switched parallel to the switching of the at least one switching element of the operating device by the power switching elements of the at least one control unit.

4. The electromotive furniture drive of claim 2 , wherein:

the at least one switching element of the at least one operating device includes a power switching element configured to switch a power path of the at least one electric motor,

the at least one control unit is configured as a branching unit, and

the at least one actuating element of the at least one analyzing device includes:

a power switching element configured to interrupt a power path to the at least one operating device, and

a power switching element configured to switch the power path to the at least one electric motor.

5. The electromotive furniture drive of claim 1 , wherein the at least one analyzing device is a component of the at least one control unit.

6. The electromotive furniture drive of claim 1 , wherein the at least one analyzing device is constructed to be mountable on the at least one control unit.

7. The electromotive furniture drive of claim 1 , wherein the at least one analyzing device (has includes an evaluating unit.

8. The electromotive furniture drive of claim 1 , wherein the at least one analyzing device is electrically connected downstream of the at least one power supply unit.

9. The electromotive furniture drive of claim 1 , wherein the at least one analyzing device has its own power supply.

10. An analyzing device comprising:

at least one actuating element configured to perform functionality testing of each of at least one electric motor, at least one control unit, at least one operating device and at least one power supply unit included in an electromotive furniture drive; and

at least one signaling element.

11. The analyzing device of claim 10 , wherein the at least one actuating element is configured to perform the same function as the at least one switching element.

12. The analyzing device of claim 10 , wherein the analyzing device is constructed to be one of built onto and installed in the electromotive furniture drive.
