  • Patent number: 6813939
    Abstract: A pair of car ramps is provided, each with integral rollers that allow the drive wheels of a vehicle to turn while the vehicle remains stationary. Each ramp is a two-piece unit with a removable inclined section and a separate recessed wheel section. This feature allows the units to store easily as well as aiding in transportation. Additionally, the recessed wheel section is lined with a series of rollers with bearings. These rollers are what allows the drive wheels to turn, while the vehicle remains stationary. The rollers are also provided with a locking mechanism that prevents the rollers from moving to allow the vehicle to drive on and off the invention. A separate but stationary roller prevents the tire from overshooting the recessed rollers. All surfaces that contact grade are covered with rubber protectors to prevent damage.
