  • Patent number: 7415986
    Abstract: Disclosed herein is a reinforced structure for collapsible and wind resistible umbrella comprising a telescoping backbone, an upper and a lower nests, a plurality of multi-sectionalized main umbrella ribs and auxiliary ribs, a first and a second umbrella covers, and a plurality of resilient bands. An elaborately designed jointing technique is applied to joint these main and auxiliary ribs so as to substantially reinforce the mechanical strength of the umbrella to withstand the wind force. The last section of each main rib divided into parallelly laid, shorter first subsection and longer second subsection makes it possible to lay two umbrella covers in a manner leaving a fissure therebetween so as to release the wind flowing out. Furthermore a resilient band is provided between each first subsection of the main rib and the second umbrella cover that contributes to keeping a definite separation between the first and second subsections of the main rib so as to prevent the umbrella from overturning.

  • Patent number: 7063434
    Abstract: A light source for an umbrella directly attached to its grip is set forth herein, a light source housing containing a light source, a battery unit, and a light source is engaged to the bottom of the umbrella grip. The battery power is directly supplied to the light source without using the electrical wiring. LED(s), or other high intensity lamps may be employed as the light source. The front portion of the light source housing is formed into a sloped surface serving as a refractor to conduct the light beam downwards and distribute it on the ground under the umbrella so as to assist the umbrella carrier walking at a dark, rainy night securely without the worry of a possible traffic accident.
