Elevated parking/storage device (with no effect on existing ground parking/storage space)

Abstract

A multi-level parking or storage device is designed to park/store goods to upper decks independently from the goods stored on the ground level. The device is designed in such a way that a platform can be moved up and down at left of the existing parking/storage space; and it can be moved left and right over the existing parking/storage space. When the platform is directly over the existing ground parking/storage space, there are only sets of additional posts grouped together and situated at the inner side of the back end of the existing parking/storage space. This design can multiply the efficiency of an existing parking/storage space without sacrificing or changing the current utility of the ground space.

The claims are:  
     
         1 . A parking or storage device that is composed of two major parts. One part is a platform that can be moved up and down along two roller posts. The other part is the two horizontal arms supported by a fixed structure on one end, and each connected to a roller post by a moving mechanism; the roller posts can be moved left and right along the horizontal arm. With this design, the bending force on the “arm” incurred by the weight carried on the platform would not change with the position of the roller post. When the car or goods is on the upper deck and directly over the ground parking/storage space, there will be only sets of posts sitting at one end and inside of the existing ground parking space. Nothing sticks out to the other end of the ground parking/storage space.  
     
     
         2 . The said horizontal arm is equipped with a sky rail car driven by a motor.  
     
     
         3 . The farthest position that the sky rail car can travel to the left is by a distance equal to the width of the roller post from the left end of the arm.  
     
     
         4 . Each said roller post is connected to the sky rail car.  
     
     
         5 . Other moving mechanism can also be used to move the platform and the roller posts.
