  • Display unit
    Patent number: 6427750
    Abstract: An advertising display unit has a blind wound between a pair of spaced rollers rotatably mounted for bringing a selected portion of the blind into a display window area. A mechanism for longitudinally moving the blind is provided which is easily accessed and actuated manually. Each roller comprises an assembly having a larger diameter portion onto which the blind is wound and a smaller diameter portion that rotates with it. A cord drive is secured to and wound a number of turns round the smaller diameter portion of one roller. The cord drive follows a path a section of which extends externally of a housing in which the rollers are mounted. The cord drive passes to the other roller where it is wound a number of turns about and secured to the small diameter portion of the other roller. The cord is wound about the small diameter portion so as to wind off one and onto the other with the rollers rotating in the same direction. The blind serves to transmit drive from the wind-up roller to the wind-off roller.
