6. The electromotive furniture drive of claim 4 , wherein the handset comprises a manually operable lock switch switchable to a position “lock”, in which the lock switch locks transmission of a control command to the control device for operation of the adjusting drive.
7. The electromotive furniture drive of claim 6 , wherein transmission of the control command is lockable only when received via the remote control.
8. The electromotive furniture drive of claim 1 , wherein the remote control is designed as a smartphone.
9. The electromotive furniture drive of claim 1 , wherein the remote control transmits the wireless signal according to a Bluetooth, WLAN, DECT or ZigBee protocol.
10. A furniture, comprising:
a movable first furniture part;
a second furniture part; and
an electromotive furniture drive including an adjusting drive for electromotive movement of a movable furniture component relative to a further furniture component, a remote control, a communication unit configured to receive a wireless signal from the remote control and to determine a signal strength of the wireless signal, and a control device configured to control operation of the adjusting drive in response to the wireless signal only when the signal strength of the wireless signal exceeds a predetermined threshold value,
wherein the communication unit outputs a common signal comprising a control signal reflective of a content of the wireless signal and a reception strength signal reflective of the signal strength of the wireless signal by co-transmitting the reception signal strength encoded in a data stream of the control signal.
11. The furniture of claim 10 , wherein the control device comprises a discriminator which is connected to the communication unit and configured to forward the control signal only when the reception strength signal exceeds the predetermined threshold.
12. The furniture of claim 11 , wherein at least one of the communication unit and the discriminator are integrated in the control device.
13. The furniture of claim 10 , wherein the electromotive furniture drive includes a handset and a cable connecting the handset with the control device so that the adjusting drive is controllable by the control device via the handset.
14. The furniture of claim 13 , wherein the control device comprises a discriminator which is connected to the communication unit and configured to forward the control signal only when the reception strength signal exceeds the predetermined threshold, at least one of the communication unit and the discriminator being integrated in the handset.
15. The furniture of claim 13 , wherein the handset comprises a manually operable lock switch switchable to a position “lock”, in which the lock switch locks transmission of a control command to the control device for operation of the adjusting drive.
16. The furniture of claim 15 , wherein transmission of the control command is lockable only when received via the remote control.
17. The furniture of claim 10 , wherein the remote control is designed as a smartphone.
18. The furniture of claim 10 , wherein the remote control transmits the wireless signal according to a Bluetooth, WLAN, DECT or ZigBee protocol.
19. A method for controlling an electromotive furniture drive, comprising:
sending a wireless signal from a remote control to a communication unit;
receiving the wireless signal by the communication unit;
determining a control signal reflective of the received wireless signal;
determining a signal strength of the received wireless signal;
comparing the signal strength with a predetermined threshold value;
controlling operation of an adjusting drive for electromotive movement of a movable furniture component relative to another furniture component in response to the control signal when the signal strength exceeds the predetermined threshold value; and
ignoring the control signal when the signal strength does not exceed the predetermined threshold value,
wherein the communication unit outputs a common signal comprising the control signal and the received wireless signal by co-transmitting the received wireless signal encoded in a data stream of the control signal.
20. The method of claim 19 , further comprising determining the threshold value from a magnitude of the signal strength of the wireless signal previously received during a learning phase.
21. A method for controlling an electromotive furniture drive, comprising:
sending a wireless signal from a communication unit to a remote control;
receiving the wireless signal by the remote control;
determining a signal strength of the received wireless signal;
comparing the signal strength with a predetermined threshold value; and
controlling operation of an adjusting drive for electromotive movement of a movable furniture component relative to another furniture component only when the signal strength exceeds the predetermined threshold value,
