Abstract: A folding chair including a seat frame, a leg frame hinged to the seat frame, a hinge mechanism between the seat frame and the leg frame, a quick-release locking mechanism for releasably locking the seat frame with respect to the leg frame, and a supplemental locking mechanism including an orifice in one of the seat frame and the leg frame, an opening in the hinge mechanism aligned with the orifice when the chair is unfolded, and a fastener extending through the opening in the hinge mechanism and into the orifice to secure the seat frame to the leg frame.

Abstract: A reconfigurable child's toy features a first configuration including a table with a top and a supporting pedestal and chairs about the table. A second configuration includes two or more of the chairs stacked on each other and the table top and supporting pedestal interlocked with the stacked chairs forming a play structure such as a tower, a rocket ship, or other round or square play structure.

Abstract: A fan assembly with a split collar clampable about a pole, the split collar including a drive ring support. A split motor housing is clampable about the split collar and the split motor housing includes a drive mechanism. A split drive ring is rotatably clampable about the split collar and supported by the drive ring support. The split drive ring includes a driven mechanism driven by the drive mechanism. A plurality of fan blades are coupled to the split drive ring.

Abstract: A fan assembly with a split collar clampable about a pole, the split collar including a drive ring support. A split motor housing is clampable about the split collar and the split motor housing includes a drive mechanism. A split drive ring is rotatably clampable about the split collar and supported by the drive ring support. The split drive ring includes a driven mechanism driven by the drive mechanism. A plurality of fan blades are coupled to the split drive ring. The fan assembly can be easily raised up or lowered down an umbrella pole. When the fan assembly is in the lowered position and the fan blades are removed, the umbrella can be easily stored away with the fan assembly still assembled about the umbrella pole.

Abstract: A fan assembly for an umbrella including a first integrated sub-assembly clampable about an umbrella pole. The first integrated sub-assembly has a split collar surrounding the umbrella pole, a support housing on a lower end of the collar defining a drive ring support plate, and a motor housing enclosing a motor therein on an upper end of the collar spaced from the drive ring support plate. A second integrated sub-assembly is rotatably disposable about the collar and the umbrella pole and includes a drive ring having a lower surface which is supported by the drive ring support plate of the support housing, a drive ring drive mechanism, and a plurality of fan blades coupled to the drive ring.
