<p>A device (44) for storing and delivering rotational energy to a mobile (12) is used in combination with an electrical motor (40) and a control device (28) adapted for intermittent actuation of the motor (40) for a predetermined period at predetermined intervals. The energy storage device (44) has at least one multi-filament non-braided cord (54) connected between first and second end caps (50). The first end cap is detachably connected to the motor (40) and the second end cap is detachably connected to the mobile (12). The cords (54) are wound by and in response to actuation of the motor (40) and urge the mobile (12) to rotate following deactivation of the motor (40). </p> |
