  • Patent number: 10034524
    Abstract: An umbrella hub is provided that includes an inner portion, an outer periphery, a lower portion and an upper portion. A plurality of vertical grooves is disposed in the outer periphery and is configured to receive umbrella ribs or struts. A plurality of grooves extends transverse to the plurality of vertical grooves. A retention member is disposed in each of the transverse grooves. A first configuration of the hub permits deflection of the retention member such that a transverse pin coupled with the umbrella ribs or struts can be inserted into the transverse groove in which the retention member is disposed. A second configuration of the hub prevents deflection of the retention member such that inadvertent withdrawal of the pin from the transverse groove in which the retention member is disposed is prevented.

The improved umbrella has a handle supporting a canopy section comprising of an upper canopy, a lower canopy and a collapsible frame attached to and disposed between the upper and lower canopies. An operating mechanism allows the user to move the umbrella between its open and closed positions. When being closed, the operating mechanism inverts the frame so the peripheral edge of the upper canopy is directed upward and the center area thereof is pulled down into an interior cavity at the top end of the handle so water will drain inward to the cavity instead of outward. The upper canopy is pulled into the cavity and the frame, with the lower canopy wrapped around it, is collapsed against the handle.

  • Patent number: 7513266
    Abstract: First longitudinal grooves are formed in the lateral sides of wing parts of a cap and a slider. First through holes are formed to intersect the first longitudinal grooves in the cap and the slider. Second through holes are formed in positions closer to the centers of the cap and the slider than the first through holes. In the cap, two ribs pointing in the lateral directions are individually supported to be pivotable at the first longitudinal grooves by supporting members in the first through holes, and other ribs are pivotally supported in a collective manner by a circular supporting wire passing through the second through holes. In the slider, two stretchers pointing in the lateral directions are individually supported to be pivotable at the first longitudinal grooves by supporting members in the first through holes, and other stretchers are pivotally supported in a collective manner by a circular supporting wire passing through the second through holes.

  • Patent number: 7509965
    Abstract: A ventilated umbrella includes a foldable frame, upper canopy and lower canopy. An upper and lower stopping rings with certain interval there between are disposed under the upper notched ring of the main shaft while a notched ring for string is slidable between the two stopping rings and a compression spring is between the notched ring for string and the lower stopping ring. A plurality of radial vertical slots with larger inner slots and smaller outer slots are disposed evenly on the notched ring for string so that one end of a plurality of strings is set into the vertical slot and restrained by a ring while the other end is connected to upper circumference of the lower canopy. And the connection point is located under a horizontal line formed by joints between the main ribs and the stretchers. Thereby a plurality of strings is easy to attach on the notched ring for string.

  • Patent number: 7481232
    Abstract: An umbrella having opposed moving hubs, one upper and one lower, to which is attached a series of spaced spars to the upper hub and a series of spaced ribs to the lower hub. The ribs are also connected one rib to one spar. An acme-threaded rod passes through an acme nut mounted on each hub, one left hand threaded and one right hand threaded, such that the rod, when connected to a drive shaft and gear motor, and actuated causes the hubs to move toward each other to close the umbrella and away from each other to open the umbrella. The umbrella is covered over by a canopy attached thereto.

  • Publication number: 20080202570
    Abstract: An umbrella frame provides a stable and enduring support for an umbrella canopy while also allowing canopies of varying shapes and sizes to be mounted thereto. The umbrella frame includes a hub assembly, namely, a main hub member mounted about a central pole member of the umbrella frame which offers improved means for attaching brackets thereto which are structured to pivotally receive a plurality of strut members therein, which strut members are, in turn, pivotally secured to a plurality of rib members interconnected with an upper, secondary hub. The main hub member of the present invention preferably includes an upper portion, a lower portion, and a channel having at least one ledge formed therebetween, with a band formed from a flattened strip of metal secured within the channel about the hub member.

  • 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.

  • Patent number: 7401616
    Abstract: An umbrella includes an elongated stem having telescopically connected inner and outer tubular segments, a top hub secured to the inner tubular segment to define an upper annular space therebetween, a tubular runner surrounding the stem, slidable between upper and lower positions to spread-out or collapse a canopy and rib assembly, and spaced apart from the inner tubular segment to define a lower annular space therebetween, a tubular spacer slidably sleeved on the inner tubular segment to be inserted into the lower annular space when the runner is displaced to the upper position so as to prevent wobbling movement of the runner, and movable by the outer tubular segment to be thereby withdrawn into the upper annular space when the outer tubular segment is displaced to the retracted position, and a biasing member disposed to bias the spacer into the lower annular space.

  • Patent number: 7328715
    Abstract: A device that releases an operating collar from an open position on the mast of an opened beach or patio umbrella in the presence of a strong wind, allowing the umbrella canopy to close thereby diminishing the wind force acting on the umbrella. The device includes a locking pin and an associated biasing mechanism. In a working configuration of the device, the pin is exposed for insertion through certain holes in the mast. A distal end of the mechanism faces the mast while a proximal end of the mechanism applies a bias force to a proximal end of the pin. The collar rests on the inserted pin with enough force to overcome the bias force tending to eject the pin. When the collar is urged to rise because of a strong wind acting on the umbrella, the pin ejects thus freeing the collar to move downward as the umbrella canopy closes.
