Abstract
A ramp for a vehicle comprises an elongated track with a leading end and a trailing end. The leading end engages a flatbed platform of a vehicle, and the trailing end engages a ground surface so that there is a slope between the leading and trailing ends when the ramp is in a first usage. The elongated track is constituted by multiple engaging elements. The elements are movable relative to each other so that the elements are capable of being packed in a stack to define a platform for a wheel of a vehicle. This permits raising of the wheel of a vehicle above the ground level. There is a hinge between adjacent elements, and the elements of the ramp are hinged at opposite ends for relative folding to permit for a stacked relationship about adjacent ends.

A ramp for a vehicle having two different uses comprising:
- an elongated track with a leading end including a lead member permanently affixed to the track and a trailing end, the leading member being for engaging a horizontal platform of a vehicle, and the trailing end for being engaging a ground surface so that there is a slope between the leading and trailing ends when the ramp is in a first usage relationship with the vehicle;
- the elongated track being constituted by multiple engaging elements,
- the elements being movable relative to each other whereby the elements are capable of being packed in a stack to define a platform for a wheel of a vehicle thereby to permit raising of the wheel of a vehicle above the ground level, and the raising of the vehicle above a ground level being a second usage of the ramp;
- and
- the lead member including two portions, a first portion for engaging with the element of the ramp in a substantially parallel relationship with the track, and a second portion angulated relative to the track of the ramp, the second portion being for engaging on a horizontal platform of the vehicle when in the first usage, and in the second usage the second portion being for engaging with the stacked elements thereby to provide a ramp from the floor to the top of the stacked elements for a wheel of a vehicle to roll up and onto the stacked elements.
A ramp for a vehicle comprising:
- an elongated track with a leading end and a trailing end, the leading end being for engaging a flatbed platform of a vehicle, and the trailing end for being engaging a ground surface so that there is a slope between the leading and trailing ends when the ramp is in a first usage relationship with the vehicle;
- the elongated track being constituted by multiple engaging elements;
- the elements being movable relative to each other whereby the elements are capable of being packed in a stack to define a platform for a wheel of a vehicle thereby to permit raising of the wheel of a vehicle above the ground level, and the raising of the vehicle above a ground level being a second usage of the ramp;
- a leading member permanently attached to the track including two portions, a first portion for engaging with the element of the ramp in a substantially parallel relationship with the track, and a second portion angulated relative to the track of the ramp, the second portion being for engaging on the flatbed of the vehicle when in a first use, and in a second use the second portion being for engaging with the stacked elements thereby to provide a ramp from the floor to the top of the stacked elements permitting a wheel of a vehicle to roll up and onto the stacked elements;
- a removable stop member to be received in an aperture of a top element of the ramp when in the stack to hinder a vehicle from running past the end of the element;
- enhance bars on the bottom of at least one of the elements to add strength to the ramp;
- and
- safety chains attached to the leading end to secure the ramp to the vehicle.
