  • Patent number: 6336464
    Abstract: An innovative stretcher structure used for collapsible two-layer canopy wind resistant umbrellas primarily uses a connection block in conjunction with two staggered curved portions each formed on a main tail plate and a secondary tail plate to enhance the wind resistant strength of an umbrella. When wind blows the umbrella, a stretcher according to the invention not only supports the umbrella canopy to endure wind but also provides a restoring force to counteract the overturning force exerted on the umbrella stretcher system by wind. Thus the present invention has an enhanced wind resistant strength.

  • Patent number: 5878763
    Abstract: An improved canopy structure of a bi-section foldable umbrella is provided with an integrally formed slide block having an upper slider and a lower slider. A fixing mount is integrally connected to the top of the upper slider. The fixing mount, the upper slider and the lower slider are connected to one end of positioning spreaders, extending spreaders and auxiliary spreaders respectively. A canopy is fixedly engaged with some of the spreaders. All the extending spreaders and the auxiliary spreaders are bound together in pairs by an inverted T-shaped member at the middle thereof . At the ends of each paired extending spreader and the auxiliary spreader is disposed a tri-point connector so as to permit an elongated rib downwardly extended from the connector. The periphery of a canopy can thus be vertically supported along the edge thereof for better shelter of a person under the umbrella.
