Abstract

A multi-level structure includes a number of parking levels, each level defines a number of parking stations which are arranged circularly. Four elevators are provided in a middle portion of the structure, each of the elevators is vertically movable in order to transfer vehicles to any of the levels. Each elevator can transfer two vehicles so that eight vehicles can be transferred by the four elevators at a time and so that the elevators can transfer vehicles in a fast speed.

Claims2

Dependent claims

A multi-level vehicle parking system comprising:

a multi-level structure including a plurality of parking levels, said structure being substantially cylindrical having an outer wall provided on an outer peripheral surface thereof, each parking level defining a plurality of parking stations which are arranged circularly, a plurality of curbs which altogether form a circle being formed on an outer peripheral edge of each of said parking levels, said curbs being provided to alert drivers of said vehicles so that said drivers may feel that the vehicles have been moved to a rearmost position in order that said drivers can stop said vehicles and so that said vehicles are prevented from smashing into said outer wall;
four elevators being provided in a middle portion of said structure, each of said elevators being triangular and being vertically movable in order to transfer vehicles to any of said parking levels, said elevators altogether forming a rectangle which has four corners, a post being provided in a center of said structure, a beam being provided on each of said corners of said rectangle formed by said elevators, a plurality of rollers being provided between every elevator and said post and being provided between every elevator and said beams for facilitating a vertical movement of said elevators, two pairs of radially separated and curved grooves being formed in a floor of each of said elevators, each pair of said grooves having one groove closer to said post than the other groove, a distance between each pair of said grooves being substantially equal to a distance between a front wheel and a rear wheel of said vehicle, a stop being coupled to and being slidable along each of said grooves;
and when said vehicle moves into one of said elevators, said stops can be moved behind said front wheel and said rear wheel of said vehicle so as to prevent said vehicle from moving rearward, each elevator can transfer two vehicles at a time so that eight vehicles can be transferred by said four elevators at a time and so that said multi-level vehicle parking system can transfer vehicles in a fast speed.
