  • Publication number: 20060081277
    Abstract: The present invention relates to a side-supporting umbrella. A collar is installed on a mast, and able to slide along the mast in a continuously variable manner, and pivotally connected to a supporting arm of a canopy. A movement of the collar sequentially actuates another movement of the pivotally interlinked supporting arm to adjust the tilt of the canopy, and the collar can be fixed at any position of the mast by a locking element. Thus, the canopy can be adjusted to any tilt attitude in response to the solar radiation coming from any direction. Besides, a controlling line of the present is inside-installed in order to prevent the line from exposure to the environment and avoid wear or damage of the line and then prolong the life of the umbrella and promote the operating safety.
