  • Patent number: 4246982
    Abstract: A car ramp and drip pan assembly for placement under parked motor vehicles to catch fluid and particle drippings therefrom including a rectangular tray for catching the drippings, a pair of elongated racks positioned in the tray parallel to the sides of the tray and upon which the vehicle is driven thus spacing the vehicle wheels above the bottom of the tray so that the wheels do not touch the drippings, and a ramp connected to the entrance edge of the tray enabling easy entry of a vehicle onto the racks. A pair of tire stops is selectively positionable on the racks for stopping the vehicle at a predetermined position on the assembly. The tray perimeter is formed of a continuous upstanding flange to contain the drippings within the tray. The ramp has a transverse slot formed in its underside to coactively fit onto the flange on the entrance edge of the tray. The racks and ramp have their upper surfaces corrugated to provide traction for the vehicle wheels.
