Two-story parking apparatus with adjustable ramp angle

A two-story parking apparatus comprising:

• a supporting frame (1), an upper platform 22 slidably held in an upper parking means (2) and pivotally mounted by a shaft (13) on an upper portion of the supporting frame (1) with said upper platform 2 normally horizontally held on said frame (1), a tilting means (3) mounted on said upper parking means (2) and said frame (1) and operatively forwarding the upper platform (22) to forwardly move a gravity center of the upper parking means (2) loaded with an upper car thereon to be positioned in front of the shaft (13) to bias the upper platform (22) about the shaft (13) for downwardly tilting the upper platform (22) for providing an inclined ramp adapted for a downwardly driving of an upper car from the upper platform (22) towards a ground floor or for an upward parking of the upper car through the inclined ramp from the floor to be loaded on the upper platform (22), a restoring means (4) for retracting the upper platform (22) to be horizontally held on the supporting frame (1) when stopping operation of said tilting means (3), and a drag means (5) secured to a rear portion of the upper platform (22) and to a lower platform (6) positioned below said upper parking means (2) for simultaneously rearwardly pulling the lower platform (6) as the upper platform (22) is downwardly tilted to prevent damage to a car parked on the lower platform (6) by the upper platform (22).
