Patent number: 6511123Abstract: 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.Type: GrantFiled: October 22, 1999Date of Patent: January 28, 2003Assignee: Mattel, Inc.Inventors: Gerald P. Sitarski, Chinawut Paul Paesang

Patent number: 6508322Abstract: 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.Type: GrantFiled: October 31, 2001Date of Patent: January 21, 2003Assignee: Mattel, Inc.Inventors: Daniel M. Dignitti, Gerald P. Sitarski, John L. Jones, Jr.

Patent number: 6470982Abstract: 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.Type: GrantFiled: February 8, 2001Date of Patent: October 29, 2002Assignee: Mattel, Inc.Inventors: Gerald P. Sitarski, Daniel Dignitti, Steven Robert Drosendahl, Walter C. Miazga, Douglas A. Knight
