Abstract: A parking device includes a first vertical support post; a first horizontal arm cantilevered from the first vertical support post; a first vertical roller post connected to and horizontally moveable along the first horizontal arm, the first vertical roller post having a first wheel disposed on the bottom thereof, the first wheel acting to support the first vertical roller post; a parking platform connected to the first vertical roller post and capable of moving vertically along the first vertical roller post; a first moving mechanism for moving the parking platform vertically along the first vertical roller post; and a second moving mechanism for moving the first vertical roller post horizontally along the first horizontal arm.

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.
