Abstract
Abstract A plurality of ramp planks of a predetermined thickness are stackable on a frame, to determine the height of the ramp. Each successive plank, in the upper direction, is shorter than the one below it. The number of planks utilized determines the height of elevation of the wheel. The degree that a vehicle is off level is measured by an inclinometer carried by the vehicle. The reading on the inclinometer tells the user the number of ramp planks he should use so that when a low side wheel of the vehicle is driven up onto the ramp, the vehicle will be substantially level. Indicia is provided on the ramp planks corresponding to indicia on the inclinometer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
224 words
An apparatus for leveling a vehicle by elevating a wheel of the vehicle, comprising: a leveling ramp comprising a base frame including a bottom member, and a plurality of plank members of graduated lengths stackable on the bottom member, said plank members forming a gradual incline at one end of the ramp when stacked together and on the bottom member, with the height of the leveling ramp being adjustable by the removal or addition of one or more of the ramp planks, said base frame further including a pair of side members which are substantially shorter than the bottom member and which are connected to the bottom member at one end thereof, said side members projecting vertically upwardly, and a rear end member interconnected between said side members to form a three sided receptacle at the end of the bottom member in which rear end portions of the plank members are snugly received when they are stacked together and on the bottom member, said receptacle serving to hold the plank members in stacked position relative to each other and the bottom member at its end of the ramp, said rear end member always projects upwardly above the upper surface of the top plank member to serve as a wheel stop for the wheel of the vehicle which is driven up onto the leveling ramp.

Claim 3
Dependent Claim
32 words
An apparatus for leveling a vehicle according to claim 1, further including vertical dowl joint connection means connecting forward end portions of the ramp plank members together and to the bottom member.
Claim 4
Dependent Claim
80 words
An apparatus for leveling a vehicle according to claim 1, further including pendulum inclinometer means to be carried by the vehicle having scale indicia for indicating the amount that a vehicle is out of level prior to leveling of the vehicle, and indicia on the ramp plank members corresponding to indicia on the inclinometer, so that a user can read the pendulum inclinometer scale indicia and accordingly select the proper number of ramp plank members necessary to level the vehicle.
