Abstract:
1. A portable personal vehicle turntable apparatus comprising: an outer platform, said outer platform further comprising a bottom layer and a top layer fixedly attached to each other, said bottom layer of said outer platform further comprising a plurality of indentations for cradling a plurality of ball bearings, said top layer further comprising an outer edge and a large circular opening, said outer edge of said top layer of said outer platform being sloped upward towards the center of the apparatus and said large circular opening further comprising a circular gear; an inner platform having a circular shape and a diameter smaller than the diameter of the large circular opening of the top layer of the outer platform, said inner platform further comprising a bottom layer and a top layer fixedly attached to each other, said bottom layer of the inner platform comprising a smooth lower surface for contact with the ball bearings of the bottom layer of the outer platform, said top layer of the inner platform comprising a rectangular opening; a pair of parallel drive shafts rotatably attached to said inner platform, a portion of said parallel drive shafts being accessible through said rectangular opening of said top layer of the inner platform such that the rear tire of a personal vehicle may contact each drive shaft of said pair of parallel drive shafts; a pair of drive shaft gear heads fixedly attached to the pair of parallel drive shafts wherein each drive shaft has one and only one drive shaft gear head, for meshing with the circular gear of the circular opening of the top layer of the outer platform; and a recoil mechanism, operating from a rest to a loaded position, fixedly attached to the center of the bottom layer of the outer platform and rotatably attached to the inner platform, said recoil mechanism further comprising a recoil spring, said recoil spring having a spring constant that allows the inner platform to reverse one hundred eight degrees, from the loaded position to the rest position, when a personal vehicle has exited the apparatus, and a trigger that releases said recoil spring thereby initiating the return to the rest position from the loaded position.
