Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A vehicle ramp upon which one wheel of a vehicle can be driven for raising the body of the vehicle above normal ground level, comprising: a platform section having a substantially horizontal top surface member on which the vehicle wheel rests, said surface member being supported on uprights extending to ground level, said uprights being sufficiently strong to support the wheel and associated weight of the vehicle; a ramp section having a ramp member with one end at ground level and the other end extending at an angle to the ground to the height of and adjacent to the platform surface member whereby the vehicle wheel can be driven onto the one end of the ramp and up the ramp onto the top surface member; a foot pad having a bottom surface adapted to engage the ground and resist slipping along the ground; means extending downward and in the direction of movement of the wheel and the foot pad for transmitting the force resulting from the vehicle wheel rolling upon the ramp section directly to the foot pad thereby pressing downward on the pad to anchoR the vehicle ramp against sliding movement in the direction the vehicle is being driven upon mounting the ramp.
Claim 2
Dependent Claim
204 words
A vehicle ramp upon which one wheel of a vehicle can be driven for raising the body of the vehicle above normal ground level, comprising: a platform section having a substantially horizontal top surface member on which the vehicle wheel rests, said surface member being supported on uprights extending to ground level, said uprights being sufficiently strong to support the wheel and associated weight of the vehicle; a ramp section having a ramp member with one end at ground level and the other end extending at an angle to the ground to the height of and adjacent to the platform surface member whereby the vehicle wheel can be driven onto the one end of the ramp and up the ramp onto the top surface member; a foot pad having a bottom surface adapted to engage the ground and resist slipping along the ground; means extending downward and in the direction of movement of the wheel and the foot pad for transmitting the force resulting from the vehicle wheel rolling upon the ramp section directly to the foot pad thereby pressing downward on the pad to anchoR the vehicle ramp against sliding movement in the direction the vehicle is being driven upon mounting the ramp.
Claim 3
Dependent Claim
39 words
A vehicle ramp as defined in claim 1 wherein said means extending downward and connecting with the foot pad comprises an elongated member having the end opposite the end fixed to the foot pad pivotally connected to the ramp.
Claim 4
Dependent Claim
37 words
A vehicle ramp as defined in claim 1 wherein the means connecting the ramp is rigidly fixed to the ramp member and the ramp member is pivotally fixed only at its lower end to the platform section.
Claim 5
Dependent Claim
40 words
A vehicle ramp as defined in claim 3 wherein the ramp member is concave shaped such that the end adjacent to the ground is at a lesser angle to the horizontal than the end adjacent to the top surface member.
