  • Patent number: 11445790
    Abstract: A novel umbrella is disclosed with a simplified structure that creates a clean, elegant profile with reduced component count and increased wind resistance. The umbrella includes a support post, a housing supported thereby, spokes pivotally disposed about the housing, a canopy, and an actuator. The housing has a top hub and a bottom hub. The actuator slides the hubs together to pivot the spokes away from the housing, whereby the umbrella moves from a closed position to an open position. Rollers are preferably retained within the top hub, and each spoke preferably has a spoke cam attached to one end. The spokes pivot away from the housing by having a roller surface of each spoke cam slide along each respective roller. The actuator may have a crank operated worm drive mechanism to raise and lower the canopy.

  • Patent number: 10092069
    Abstract: An umbrella has a plurality of ribs attached to a runner by main struts. The umbrella has an anti-inversion mechanism formed of a plurality of anti-inversion struts. Each anti-inversion strut is pivotally coupled to one respective main strut and is pivotally connected to a floating joint member that is freely movable along a length of one respective rib. The anti-inversion mechanism also includes a stop that is fixedly attached to the rib and restricts the degree of travel of the floating joint member along the rib and is positioned to prevent the respective rib from inverting in response to an applied force.

  • Patent number: 9022049
    Abstract: An improved umbrella top notch and runner are provided for an umbrella including a shaft, plural ribs, and plural stretchers, in addition to the top notch and the runner. The top notch, structurally the same as the runner, includes a main body and plural building blocks. Each building block has a threaded hole through which a screw rod can pass to fasten the building block to the periphery of the main body. Each building block has a projecting pin on one lateral side and a recess on the opposite lateral side. When the building blocks are fastened to the periphery of the main body, the front end of the projecting pin on one lateral side of each building block is fittingly received in the recess of the adjacent building block. Each building block can be detached from the main body to facilitate replacement of the ribs and stretchers.

  • Patent number: 9016296
    Abstract: An umbrella structure includes a shaft, a top notch fixed at the top end of the shaft, a runner mounted around and slidable along the shaft, plural ribs, plural stretchers, a canopy, and plural torsion springs. Each rib has an upper end pivotally connected to the top notch. Each stretcher has an upper end pivotally connected to an intermediate portion of one of the ribs and a lower end pivotally connected to the runner. The canopy can be opened or closed by sliding the runner upward or downward along the shaft. One torsion spring is provided where each rib is pivotally connected to the corresponding stretcher. When the runner is slid downward to close the canopy, each torsion spring is compressed and stores energy. When the runner is slid upward to open the canopy, each torsion spring releases the stored energy to reduce the effort required for opening the canopy.

    Abstract: The invention disclosed is a movable connection structure for an umbrella rib and an umbrella rib using the same. The movable connection structure includes a first connector arranged on a first umbrella rib and a second connector arranged on a second umbrella rib. The first connector and the second connector are connected by a folding junction portion. The first connector, the second connector, and the junction portion are made of a plastic material and formed into an integral element. The present invention avoids specialized manufacturing equipment. The present invention eliminates hole drilling steps and rivet punching steps otherwise required during the manufacture of a movable connector. The movable connection structure and the umbrella rib using the same are conveniently and quickly assembled, thereby minimizing manual labor, improving production efficiency, and reducing production cost. The present invention provides a sturdy and durable umbrella structure.

  • Patent number: 7401617
    Abstract: An umbrella has a shaft having upper and lower ends, a slide piece, and a head piece. One of the pieces has an upper part and a lower part having faces that are engaged together and that form a plurality of seats of predetermined diameter spaced angularly about the shaft. The parts are also formed at each seat with a radially outwardly open and axially extending notch of an angular width substantially smaller than the diameter of the respective seat. They are fixed together at the faces. Respective rib or strut elements each have a shaft of a width at most equal to the notch width and a head of a diameter smaller than the seat diameter. The heads are received in the seats and the shafts project outward from the respective seats through the respective notches. A standard canopy is fitted over the ribs outside the head piece.

  • Publication number: 20080163912
    Abstract: An umbrella includes a staff assembly, a plurality of upper ribs, a plurality of corresponding lower ribs and a canopy. The staff assembly includes an inner staff member and an outer staff member slidably mounted thereon. The upper ribs are pivotally connected to the inner staff member. The lower ribs are pivotally connected to the outer staff member and to the upper ribs. The canopy is mounted on the upper or lower ribs. Sliding the inner and outer staff members with respect to each other in a longitudinal direction thereof shifts the ribs and the canopy between a deployed position in which the ribs and canopy extend generally radially outwardly from the staff assembly so as to open the umbrella, and a retracted position in which the ribs and the canopy are collapsed inwardly toward, the staff assembly so as to close the umbrella.
