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.

Abstract: A vehicle ramp for raising a vehicle wheel having an incline component and a separate but interlockable elevated wheel support component. The incline component can be removed while the vehicle wheel is resting on the corresponding elevated wheel support component. The elevated wheel support component has an adjustable chock. In addition to a rear stop on an end, a chock with a raised section helps keep the vehicle wheel from rolling off the top horizontal surface. The removal of the incline component while the vehicle rests on the elevated wheel support component is accomplished with an interlocking member that does not extend the entire height of the interlocking sides of the primary components. Hand grips or handles can be formed in recesses of the sides of each component.

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.

Abstract: A modular wheel lift provides elevation of a vehicle wheel enclosed by body portions of a low height above the ground. A base lift unit includes a lift surface height selected to be less than the body portions height. A ramp unit is aligned and hingedly attached to one end of the base lift unit, to allow rotational movement of a wheel to the base lift surface. Additional lift units having ramp ends and progressively decreasing lengths are laterally positioned and stacked on the base lift surface. Side brackets are releasably positioned along either side surface to secure the stacked additional lift units to allow rotational movement of the vehicle wheel to an uppermost lift surface. A method of assembly and elevating includes laterally positioning and stacking a plurality of lift units having progressively shorter lengths to provide lifting of a vehicle wheel without disruption of the vehicle body portions.

Abstract: The present invention is a set of at least three interlocking blocks where two of the blocks are set on a ground surface and are connected at their top surfaces by a particular configuration of the underside of the third block. Four square and raised parts with four key recesses are formed on the top side of the entirely plastic and unitarily molded block to mate with a cavity and four flanged posts on the underside of another identical block. The critical part of this invention is providing four key recesses in the raised part of the block into which interlock the flanged posts of the underside of the block.

Abstract: This portable car ramp has two structural components coupled longitudinally together, while allowing limited relative vertical movement when each's bottom edge rest on a medium surface. The first component has an elevated wheel run while the second component has an inclined wheel run. When coupled together, the component wheel runs are longitudinally aligned, meeting at a corner, so that a vehicle wheel can roll up the inclined run, over the corner, and onto the elevated run, and vice-versa. Friction pads fixed to the second component bottom edge increase resistance against ramp sliding along the medium surface, particularly with the wheel supported on the inclined wheel run. The first component has no bottom edge friction pads so that car ramp sliding along the medium surface is possible, such as should the wheel be rolled against a stop on the elevated wheel run.

Abstract: A vehicle ramp system for elevating a vehicle off the ground. Tires on one end of a vehicle are driven onto a first set of modified ramps.

A second set of ramps is then placed on the opposite side of a second set of tires that are provided on the opposite end of the same vehicle. The vehicle is then reversed in direction so that the second set of tires rolls up onto the second set of ramps until the second set of tires rest on elevated platforms provided on the second set of ramps and the first set of tires are retained on the platform of the first set of ramps.
