  • Patent number: 5729103
    Abstract: A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. Alternatively, the rotor is coupled to the tilt rod of the blind to rotate the tilt rod and thereby open or close the slats of the mini-blind. A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor. The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal. The actuator can be used to rotate the slats of horizontal or vertical blinds, or the sections of a pleated shade. Or, the actuator can be used to rotate the hollow rotatable tube of a roll-up shade.

  • Patent number: 5725040
    Abstract: A suspension cord guide for a window blind includes an L-shaped guide member positioned within the head rail of the blind. The guide member is positioned adjacent an opening in the head rail through which the suspension cord extends. Also, the suspension cord guide includes a hollow spindle surroundingly engaged with a tilt rod in the head rail, and the spindle is formed with an abutment surface on its end nearest the opening. A finger of the L-shaped member extends toward the spindle, with the suspension cord being fed onto the spindle next to the abutment surface by the guide member. In addition to guiding the cord onto the spindle, the finger of the L-shaped guide member contacts the coil of the suspension cord that is established on the spindle nearest the finger.
