Patent number: 8202137Abstract: Toy aircraft may include an airframe, a modular power system, first and second wheel supports, and first and second wheels. The modular power system may be configured for selective use with and selective removal from the airframe. The power system may include a propulsion unit operable to propel the toy aircraft and a power unit, which may include an energy source configured to supply energy to the propulsion unit. The airframe may include a fuselage, a propulsion unit mount, which may be disposed on the airframe and configured to removably retain the propulsion unit, and a power unit mount, which may be disposed on the fuselage and configured to removably retain the power unit. The first and second wheel supports may extend from the power unit mount toward respective first and second wheel mounts to which the first and second wheels may be rotatably mounted.Type: GrantFiled: January 31, 2011Date of Patent: June 19, 2012Assignee: Mattel, Inc.Inventors: Nicholas Amireh, Paulo King, David Strom, Chi Keung Chui

Patent number: 8133089Abstract: Toy aircraft, modular toy aircraft, capacitor-based modular power systems, and toy aircraft kits are disclosed. Toy aircraft may include a self-contained power system and an airframe. The self-contained power system may include at least one propulsion unit operable to propel the toy aircraft and a power unit. The power unit may include a capacitor that is electrically connected to the at least one propulsion unit. The capacitor may be configured to provide power to the at least one propulsion unit to propel the toy aircraft. The airframe may include a wing, a first mount configured to removably retain the at least one propulsion unit, and a second mount configured to removably retain the power unit.Type: GrantFiled: April 25, 2007Date of Patent: March 13, 2012Assignee: Mattel, Inc.Inventors: Nicholas Amireh, Paulo Kang, David Strom, Chi Keung Chui

Patent number: 8109802Abstract: A toy helicopter has a fuselage having a front end a rear end and two lateral sides. A main motor is supported from the fuselage. A main rotor is operably connected to the motor and has at least one rotor blade that rotates about a center axis generally laterally centered with respect to the fuselage. The at least one rotor blade is configured and positioned to provide lift and has a rotational path having a maximum radius. A bumper is fixedly connected to the fuselage, is spaced entirely axially downwardly from the at least one rotor blade and extends radially outwardly from and at least partially around the fuselage. At least a portion of the bumper has a maximum radial dimension from the center axis at least as great as the maximum radius of the rotational path of the at least one rotor blade.Type: GrantFiled: September 2, 2008Date of Patent: February 7, 2012Assignee: Mattel, Inc.Inventors: Chi Keung Chui, Paulo Kang
