Patent number: 10398995Abstract: A motorized toy vehicle or Wall Racer that is capable of operating on vertical and inverted horizontal surfaces such as walls and ceilings, while being manufacturable at reasonable cost and operable on batteries having sufficient lifetime as to be enjoyable. One or more battery-powered fans draw air from around all or defined portions of the periphery of the chassis of the Wall Racer through a carefully-shaped duct, so that the air in the portion of the duct immediately adjacent the surface flows at high velocity and low pressure; the relatively greater pressure of the surrounding air urges the vehicle against the surface, allowing it to operate on vertical surfaces, such as walls, or inverted on horizontal surfaces, such as ceilings.Type: GrantFiled: June 9, 2017Date of Patent: September 3, 2019Inventors: Leonard R. Clark, Jr., Peter H. Greene, Jr.

Publication number: 20090149112Abstract: A radio-controlled toy skateboard comprises a deck and front and rear trucks. The individual wheels of the rear truck can be controlled separately responsive to radio signals from a remote transmitter for rotation in either direction, while the front wheels rotate freely. Also responsive to radio control signals, the rear truck is controllably pivoted with respect to the deck about a kingpin axis that is inclined rearwardly, while the front truck pivots freely about a forwardly inclined kingpin axis. When the rear truck is thus pivoted, the deck tilts about its longitudinal centerline, causing the front truck to pivot correspondingly, steering the skateboard. A pair of modeled shoes are mounted for free pivoting about pivot axes. As the board tilts toward one side or the other, the shoes pivot from a toes-in to a toes-out position, mimicing the foot movements of a live “skater”. The forward shoe is mounted on a trolley sliding freely on an inclined ramp.Type: ApplicationFiled: December 6, 2007Publication date: June 11, 2009Inventors: Leonard R. Clark, JR., H. Peter Greene, JR.

Patent number: 6971942Abstract: A rotary feedback mechanism includes a first set of electrically conductive pads mounted to a first member and a wiper mounted to a second member. As the first and second members rotate relative to one another, the wiper sequentially contacts one or more pads of the first set of pads and provides an electrical signal to the contacted pad or pads. The electrical signal is communicated via the pad or pads to a controller, providing the controller with an indication of the angular position of the first member relative to the second member.Type: GrantFiled: January 14, 2004Date of Patent: December 6, 2005Assignee: Mattel, Inc.Inventors: Ernest D. Baker, Leonard R. Clark, Jr., Jesse Dorogusker, David Vincent Helmlinger, Eric David Listenberger, Joseph Thomas Moll, David Ribbe, Stephen N. Weiss

Publication number: 20040200924Abstract: A vertical take off and landing aircraft toy has a fuselage with a plurality of fins and a rotor assembly. The rotor assembly may be driven by an electric motor, powered by a battery, an air motor powered by compressed air, or a gasoline engine, radio controlled in each case to control the speed of the motor. The rotor assembly includes a head portion coupled to the motor output shaft, a central hub coupled to the head portion, and a pair of airfoil blades. The head portion allows pivoting of the central hub about an axis generally aligned with the axis of the blades, while the blades are pivotable with respect to the central hub about an orthogonal axis. The fins on the fuselage resist counterrotation of the fuselage with respect to the rotation of the blades; alternatively, a pair of counterrotating blades may be provided.Type: ApplicationFiled: January 26, 2004Publication date: October 14, 2004Inventors: Leonard R. Clark, H. Peter Greene

Patent number: 6726523Abstract: A remote-controlled toy skateboard device comprises a skateboard with a deck and front and rear truck assemblies pivotally connected to the deck. A toy figure has a lower body portion that is fixedly connected to the deck and an upper body portion that is connected for rotation with respect to the lower body portion. A torso drive mechanism is operably connected to the upper body portion of the toy figure to rotate the upper body portion with respect to the lower body portion. A steering mechanism is operably connected with one of the truck assemblies to tilt the deck with respect to the truck assemblies to thereby steer the skateboard. A drive mechanism is also operably connected to wheels of one truck assembly to propel the skateboard. A remote-control unit is configured to generate signals to remotely control movement of the toy figure, tilt between the deck and truck assemblies, and the speed and travel direction of the skateboard.Type: GrantFiled: February 8, 2002Date of Patent: April 27, 2004Assignee: Mattel, Inc.Inventors: Ernest D. Baker, Leonard R. Clark, Jr., Jesse Dorogusker, David Vincent Helmlinger, Eric David Listenberger, Joseph Thomas Moll, David Ribbe, Stephen N. Weiss
