ABSTRACT:
An improvement in a vehicle ramp facilitates easy storage and quick and simple conversion from a stored, collapsed state to an open, in-use state. The vehicle ramp comprises a pair of plate members pivotally coupled together along one side of each respective plate member which, being supported by a frame arrangement articulately connected to the plate members, permits the plate members to be selectively pivoted with respect to one another to either form a functional raised vehicle ramp configuration, or form a storable, collapsed, low profile configuration in which the two plate members lie in substantially a common plane, along with the articulated frame arrangement.
