Patent number: 7651041Abstract: Blades on a rotating grinding plate force waste against a stationary grinding ring. The blades are mounted on radially aligned guides on the grinding plate, allowing the blades to move freely inwardly and outwardly between opposing stops. The blades are thrown outward by rotation of the grinding plate. A receding face on the blades cooperates with the grinding ring for moving the blades inwardly and for forcing waste against the grinding ring.Type: GrantFiled: May 30, 2007Date of Patent: January 26, 2010Assignee: Chiaphua Components LimitedInventor: Bao Tao Wu

Patent number: 7562666Abstract: Radially disposed ribs for supporting the canopy of an umbrella are pivotally connected by a crown mounted on the outer end of a rod. A sleeve is in external sliding relationship with the rod. Struts are pivotally connected to the sleeve, each strut being associated with one of the ribs for splaying the ribs and collapsing them inwardly. A support tube is connected by a coaxial shaft to the rod, and the sleeve is telescopically received in the support tube. The shaft is threaded and rotated by motor, opposing ends of the threaded shaft being supported for rotation in first and second journals fixed within the support tube and the rod, respectively. A threaded nut fixedly connected to the sleeve is engaged with the threaded shaft for moving the sleeve along the rod between extended and retracted positions.Type: GrantFiled: July 27, 2006Date of Patent: July 21, 2009Assignee: Chiaphua Components LimitedInventor: Ping Chiu Chan

Patent number: 7406976Abstract: A winch for opening and closing an umbrella includes a winch drum mounted within an elongate support tube of the umbrella, to rotate about a longitudinal axis thereof. A threaded shaft is coaxial and rotationally fast with the drum. A line is fixed at one end to the drum and at other end to a sleeve, to which struts are pivotally connected, each strut being associated with a canopy-supporting rib. A travelling nut is engaged with the threaded shaft and blocked for rotation relative to the tube. A guide is fixed to the nut for guiding the line onto the drum, and a motor is also enclosed in the support tube and drivingly connected to the winch drum.Type: GrantFiled: March 29, 2007Date of Patent: August 5, 2008Assignee: Chiaphua Components LimitedInventors: Ping Chiu Chan, Bao Tao Wu, Xiang Li
