  • Tiltable and rotatable canopy frame for a sunshade
    Patent number: 6575182
    Abstract: A sunshade comprises a main post, a canopy frame, and a tilting and rotating assembly mounted between the main post and the canopy frame. Rotation of a handle on the main post in a direction causes the canopy frame to move from a folded state to an unfolded state. Further rotation of the handle in the same direction causes the canopy frame to tilt, and still further rotation of the handle in the same direction causes the tilted canopy frame to turn relative to a longitudinal axis of the main post until an optimal shield is obtained.
