Patent number: 8469369Abstract: A combined seat with compression device for interactively actuating a sound effects unit incorporated into a ride on toy vehicle as a user bounces up and down on the combined seat with compression device. The toy includes a frame for a ride-on toy vehicle, a sound effects unit having a housing secured to the frame, a seat secured to the frame and movable between first and second positions, an actuating mechanism attached at the seat for engagement with the sound effects unit, and a deformable compression device positioned at the seat capable of depressing as the seat is moved from the first the position to the second position to interactively activate the sound effects unit.Type: GrantFiled: March 11, 2011Date of Patent: June 25, 2013Assignee: Hasbro, Inc.Inventors: Thomas C. McCarthy, Craig McElhaney, Steven Lee Unruh

Patent number: 8459679Abstract: A pivot mechanism includes a base member configured to be coupled to a first element and a generally cylindrical rotating member configured to be coupled to a second element. An elongate pin extends through the base member and rotating member and defines a pivot axis. The rotating member is capable of rotating relative to the base member about the pivot axis. The elongate pin is movable in a direction generally parallel to the pivot axis between a secured position and a release position. In the secured position, the rotating member is prevented from rotating relative to the base member, and in the release position, the rotating member is permitted to rotate relative to the base member. The pivot mechanism may be incorporated into a scooter or a tricycle to provide different configurations thereof.Type: GrantFiled: July 19, 2010Date of Patent: June 11, 2013Assignee: Huffy CorporationInventor: Donald K. Jessie, Jr.

Patent number: 8388004Abstract: A personal transportation device comprises a riding platform supported by one or more wheels, a steering mechanism at least partially embedded in the riding platform and a drive wheel assembly. A first wheel may be steerable while a second wheel is a slave wheel. The steering mechanism may be foot-operated. The drive wheel may be hand-propelled and non-steerable. The drive wheel is operatively connected to a drive sprocket and chain and is coupled to the riding platform by a platform frame. The personal transportation device may comprise one or more track arm assemblies coupled to the drive wheel assembly such that movement of the track arm assemblies operates the drive wheel assembly and rotates a drive wheel to propel the vehicle.Type: GrantFiled: May 12, 2010Date of Patent: March 5, 2013Inventor: Edward Walter

Patent number: 8342555Abstract: One embodiment of a tricycle (20) having a spine frame (22), supported by a rear wheel (34) and a pair of steerable front wheels (36), and supporting a recumbent seat (42) pivotably attached at its rear. A pedal boom (44) extends forwardly of the spine (26) and supports a pedal crank assembly (46). The front wheels each support a lateral arm (28) with the front wheel pivotably attached at the distal end and an angular projection (80) attached at the proximal end. A pivot (78) connects each angular projection to the spine, allowing the lateral arms and attached front wheels to fold to a stowed position alongside the spine. Another pivot (84) connects the boom to the spine, allowing the boom fold back to a stowed position against the spine. In the travel position, a clamp arrests the angular projections, and can arrest the boom and seat. The tricycle is collapsible to several levels of compactness. Other embodiments are described and shown.Type: GrantFiled: July 21, 2010Date of Patent: January 1, 2013Inventors: Alan Roy Ball, Eric John Ball

Patent number: 8328213Abstract: A vehicle powered by an operator's arms and/or legs utilizes a pivot column for propulsion. An upper propulsion member (handlebar) is provided on the upper end of the pivot column. A lower propulsion member (foot bar) is provided on the lower end of the pivot column. A drive propulsion system is provided between the pivot column bottom and a rotational drive gear set. The drive propulsion system engaged with said at least one rotational drive gear, the propulsion system engages with and provides propulsion to an upper portion of the rotational drive gear during a counterclockwise motion of the pivot column and engages with and provides propulsion to a lower portion of the rotational drive gear during a clockwise motion of the pivot column. The rotational drive gear spins freely when subjected to the reverse motion. Incorporating two gears with opposing propulsion drives provides forward motion throughout the entire reciprocating stroke of the pivot column.Type: GrantFiled: February 21, 2011Date of Patent: December 11, 2012Inventor: Robert Crawford
