<p>The wall-mounted electric motor with a driction wheel drive is used for displacing curtain runners, and applies traction to the cord (10) which is attached to the curtains. A three wheel drive system is used, and the motor is mounted in a rectangular frame. The drive wheel (2) is mounted on a shaft which projects through the front plate (1) and is set below and between two idling rollers (3, 4). A rail guided slider (5) is mounted above the idling wheels, and has two vertical curved channels (9) which are traversed by the incoming and outgoing sections of the transmission cord (10). In plan, the cursor (5) is 'T' shaped with the leg projecting through the front panel and between two blade-spring contacts.</p> |
