    Abstract: A wind-stable umbrella includes structurally enhanced connectors for connecting ribs to an upper hub and pull cords extended between a middle hub and near-outer ends of the ribs. Each of the connectors includes a forward extended lug portion that is connected to the upper hub, and two shoulder portions extended from two lateral sides of an upper outer end of the lug portion. The shoulder portions increase a structural strength of the lug portions and press against an outer surface of the upper hub when the umbrella is stretched, so that the ribs are more stably connected to the upper hub via the connectors. The pull cords pull outer portions of the ribs inward when the umbrella is stretched, preventing the ribs from turning outward under a strong wind. The wind-stable umbrella therefore has solid overall structure to avoid twist and deformation due to the strong wind.

  • Patent number: 6095170
    Abstract: An automatically spreading and collapsing umbrella includes a plurality of rib assemblies pivoted to a ferrule on a handle, and a plurality of stretcher assemblies. Each stretcher assembly is pivoted to a runner slidably sleeved on the handle to stretch or retract a respective rib assembly when the runner is moved. An anchored member has two ends journalled on a main rib of one of the rib assemblies, and a middle portion having an anchored site which is formed as a bent strip that is vaulted upwardly. A collapsing tension spring is retained between a connecting rod of one of the stretcher assemblies and the anchored site so as to define a collapsing line along an extending length of the spring. Stretching of the rib assemblies can extend the spring to store an elastic potential energy to facilitate collapsing of the rib assemblies.

  • Patent number: 6053188
    Abstract: An umbrella comprising a central shaft having an upper end and a lower end with the lower end including a handle incorporates a plurality of pivotable members each having a first end pivotally coupled to an upper end of the shaft and being circumferentially spaced about the shaft and oriented generally parallel thereto when the umbrella is in a collapsed condition. A plurality of flexible members are operatively associated with corresponding ones of the pivotable members. The flexible members are each expandable into a generally hoop-shaped configuration adjacent another end of the pivotable members when the pivotable members are pivoted from a collapsed condition to an operative position. The open umbrella appears as a canopy stretched over a plurality of circumferentially spaced ribs with each rib terminating in a hoop-shaped member.
