Abstract

A frame supported by a base has at least an upper platform and a lower platform adapted to be nested together and supported at lower positions by the base. The upper and lower platforms are adapted to be moved upward for supporting vehicles above the ground. Lifting mechanism is provided for lifting the upper platform with a vehicle thereon to a first upper level sufficient to allow a vehicle to be located on the lower platform. Connecting straps extend between the two platforms such that when the upper platform is moved upward beyond the first upper level, the lower platform is pulled upward by the connecting straps. The lifting mechanism is adapted to move the upper platform with a vehicle thereon upward to a second upper level sufficient to pull the lower platform with a vehicle thereon to a level sufficient to allow a vehicle to be driven thereunder.

A motor vehicle parking system, comprising:

a frame comprising structural means extending upward from a base,
a plurality of platforms adapted to be nested together and supported at lower positions by said base,
said plurality of platforms comprising at least a first platform and a second platform located above said first platform,
said first and second platforms being adapted to be moved upward between said structural means,
said second platform having a first end and a second end with dimensions sufficient to allow a motor vehicle to be driven thereon from its first end when said second platform is supported at its lower position,
lifting means for moving said second platform with a motor vehicle thereon upward to a first upper level sufficient to allow a motor vehicle to be located thereunder on said first platform,
said first platform having a first end and a second end with dimensions sufficient to allow a motor vehicle to be driven thereon from its first end when said first platform is supported at its lower position,
connecting means extending between said first and second platforms such that when said second platform is moved upward beyond said first upper level, said first platform is pulled upward by said connecting means,
