Patent AT-E400339-T1: [Translated] TOY RACING MACHINE FOR THE WALL

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
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 (28) having sufficient lifetime as to be enjoyable. One or more battery-powered fans (10) draw air from around all or defined portions of the periphery of the interior volume 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 adhere to vertical surfaces, such as walls, or operated inverted on horizontal surfaces, such as ceilings.
