  • Patent number: 8272920
    Abstract: Children's ride-on vehicles are disclosed. In some embodiments, the vehicle may include first and second mechanical members, with the second mechanical member configured to move between a concealing position, in which the second mechanical member conceals a portion of the first mechanical member, and a revealing position, in which the second mechanical member does not conceal the portion of the first mechanical member. In some embodiments, a biasing member urges the second mechanical member toward the concealing position. In some embodiments, a user input device permits a child to lock the first mechanical member in one of a retracted position and an extended position.

  • Publication number: 20110124266
    Abstract: Improved blow-molded wheels, methods for producing the same, and children's ride-on vehicles including the same are disclosed. The blow-molded wheels may include a blow-molded wheel body that is configured to rotate about an axis and has a tread surface that extends circumferentially around the wheel body and may have a circumferential profile that is defined as the locus of points at which the radial distance from the axis to the tread surface is greatest at each position around the circumference of the tread surface. The radial distance from the axis to the circumferential profile may change from a first radius to a second radius that is larger than the first radius at a plurality of spaced-apart positions along the circumferential profile. The method for producing the blow-molded wheels may include providing a mold with pinch-off rings that have an opening configured to form the circumferential profile.

  • Patent number: 7938218
    Abstract: Children's ride-on vehicles having a drive assembly that is selectively configured between a plurality of drive configurations, such as responsive to user inputs via user input devices, and a ground detection system that is adapted to detect when at least one of a plurality of wheels loses contact with the ground surface. The ground detection system may be adapted to restrict the plurality of drive configurations responsive thereto. This restriction may be automatic responsive to loss of contact of the at least one of the plurality of wheels with the ground surface, and it may be made regardless, or independent, of user inputs that otherwise would select and/or enable one of the restricted drive configurations.

  • Patent number: 6511123
    Abstract: A child support device that can be converted between a highchair configuration and a swing configuration. The support device includes a frame from which a U-shaped swing arm is rotably mounted. A child seat is located on the U-shaped arm such that it can be slid between a distal position at the bottom of the U-shaped swing arm (swing configuration) and a proximal position at the upper ends of the U-shaped swing arm (highchair configuration). When in the highchair configuration, a swing lock can be provided to rotably lock the U-shaped swing arm with respect to the frame such that the seat cannot swing. The swing lock can include a retractable post that can be extended to contact a portion of the frame to prevent rotation of the swing arm. An over rotation stop can also be provided to limit the angle of rotation through which the seat swings when in the swing configuration, and to work in conjunction with the retractable post to lock the swing arm in place when in the highchair configuration.

  • Patent number: 6508322
    Abstract: A battery retaining system for a children's ride-on vehicle. The system includes a retaining member that is selectively movable between a first or nominal position in which the retaining member blocks removal of a battery assembly from the body of the vehicle, and a second position in which the retaining member does not block removal of the battery assembly. The battery retaining system also includes a biasing member coupled to the retaining member and configured to urge the retaining member from the second position toward the first position. In some embodiments, the battery retaining system is further adapted to retain portions of the vehicle other than the battery assembly.

  • Patent number: 6470982
    Abstract: A children's ride-on vehicle with a reduced scale chassis having a seat configured to accommodate at least one child. The vehicle further includes a drive assembly, which includes one or more drive wheels and a battery powered motor assembly. The battery powered motor assembly includes a motor output and a torque attenuation system, which is configured to regulate the transmission of torque from the motor assembly to the one or more drive wheels. The torque attenuation system incorporates a force reducing mechanism adapted to receive a rotational input from the motor output and regulate the transmission of that rotational input to the one or more drive wheels. In some embodiments of the invention, the torque attenuation system is a self-contained system, and in some embodiments of the invention, the torque attenuation system is adapted to be retrofit on existing children's ride-on vehicles.

  • Patent number: 6421901
    Abstract: A child support device is disclosed that can be converted between a highchair configuration and a swing configuration. The support device includes a frame from which a U-shaped swing arm is rotatably mounted. A child seat is located on the U-shaped arm such that it can be slid between a distal position at the bottom of the U-shaped swing arm (swing configuration) and a proximal position at the upper ends of the U-shaped swing arm (highchair configuration). When in the highchair configuration, a swing lock can be provided to rotatably lock the U-shaped swing arm with respect to the frame such that the seat cannot swing. The swing lock can include a retractable post that can be extended to contact a portion of the frame to prevent rotation of the swing arm. An over rotation stop can also be provided to limit the angle of rotation through which the seat swings when in the swing configuration, and to work in conjunction with the retractable post to lock the swing arm in place when in the highchair configuration.
