Abstract

A portable curb ramp (1) for wheeled vehicles and equipment (4) having a curb conforming contact surface (7) and a planar road contact surface (6) on an underside and a sloping top surface (5) to allow tires (3) to transverse from a road surface up and over a curb (2). The sloping top surface (5) may have a plurality of transverse ridges (8) for improved traction. The underside curb conforming contact surface (7) may have a lip which extends over the top of the curb and one or more ridges (9) on the planar contact surface to reduce slippage of the ramp on a road surface. Magnets (13) attached to the planar contact surface allows the ramp to be secured to metal surfaces (14) on the wheeled vehicle and equipment so the ramp is readily accessible. The curb conforming contact surface (7) may have two low bearing side walls (16) with a hollow cutout (12) in between in order to reduce the weight of the ramp.

Claims

1. A portable ramp for allowing wheeled vehicles and equipment to traverse a curb comprising:

a curb contact surface on an underside of the ramp having a shape which substantially conforms to a top surface of the curb, said curb contact surface extending from a top of the curb to a planar contact surface at a bottom;

a planar contact surface on the underside of the ramp at the bottom of the curb contact surface;

a sloping wheel contact surface on a top side of the ramp extending from a bottom to a top of the curb; and

means for removably securing the ramp to wheeled vehicles and equipment comprising at least one magnet attached to the planar contact surface on the underside of the ramp.

2. The portable ramp of claim 1 further comprising a plurality of transverse ridges at spaced intervals on the wheel contact surface to provide better traction for tires of wheeled vehicles and equipment.

3. The portable ramp of claim 2 further comprising at least one transverse ridge on the planar contact surface to provide better gripping to road surfaces.

4. The portable ramp of claim 1 further comprising at least one transverse ridge on the planar contact surface to provide better gripping to road surfaces.
