Abstract (en)
[origin: EP2746869A1] The winder (1) has a motor module (9) to drive a removable rotative support (7), and an accumulator (15) to supply power to the motor. A photovoltaic cell (13) charges the accumulator. A light sensor (21) is connected to a clockwork microcontroller (19) that is connected to an internal clock and arranged to be controlled by the user. The support is driven only in the mode when the winder is illuminated and a driving program of the support is started in another mode at an hour previously selected by a control interface (23) of the microcontroller.
