Description: BACKGROUND OF THE INVENTION This invention concerns a multi-floor elevating parking station comprising a parking frame and a stable frame, said parking frame and stable frame made up of steel posts and beams connected between two posts, said stable frame constructed under ground and containing said parking frame, motors set at the top of said stable frame rotating shafts by help of reduction gears, one ends of wire ropes fixed on said shafts and the other ends fixed at the bottom of said parking frame, said parking frame divided at an equal distance horizontally with steel plates into a plurality of parking rooms, said parking frame able to be raised up and down inside said stable frame by the rotation of the motors so that each floor plate can be made even with the ground surface for parking in or driving out a car if the parking frame is moved up. Traditional ground parking lots have to leave a comparatively broad space of drive-ways for cars to go in and out there, and traditional multi-floor parking stations have been constructed as permanent buildings which not only take time in building but also are impossible to be moved to another spot. Obviously, such parking lots and stations generally need a rather spacious area of land, and can hardly be built in an irregular or long narrow area of land. A parking station of the type as described initially is known from the US-A 37 17 266. To rise up and down the parking frame of this known parking station smoothely and steadely inside the stable frame it is necessary to use especially designed motors. It is the object of the present invention to propose a parking station as initially described, in which it is possible to rise up and down the parking frame in respect to the stable frame of the parking station smoothely and steadely in a simple manner and with a simple construction. The inventive parking station is characterized in that the stable frame is provided with pulley sets on the inside walls, said pulley sets fixed at one ends of two levers, the other ends of said levers fixed at both ends of veritical part of a T-shaped bolt, said T-shaped bolt having the horizontal part protruding out of the cover of said pulley sets and being screwed by a nut, said levers pivotally positioned by pivots set at the midway, said nut able to be screwed in or out for adjusting the gap between the pulleys and the posts of the parking frame by pushing said pulleys against said posts. SUMMARY OF THE INVENTION The inventive multi-floor elevating parking station which presents the features claimed in claim 1 is constructed under the ground instead of on the ground. It comprises a stable frame made up of steel posts and steel beams connected between two posts, and a parking frame also made up of steel posts and steel beams and divided horizontally into a plurality of floors or parking rooms with steel plates. Said parking frame is contained inside said stable frame and can be raised up and down therein by means of motors and wire ropes. Said motors are set on the top of said stable frame and rotate shafts, on which one ends of the wire ropes are fixed, and the other ends of the wire ropes are fastened at the bottom of said parking frame. Therefore, said parking frame can be raised up or down by the wire ropes wound on the shafts by the motors so that each floor or parking room can be made even with the ground surface for parking in or driving out a car.

DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows this multi-floor elevating parking station is constituted of a parking frame 1 and a stable frame 2 as the main parts, said parking frame 1 being contained inside said stable frame 2. The parking frame 1 is an oblong vertical frame made up of steel posts 11 and horizontal beams 16 connected between two of said steel posts 11 at an equal distance, divided horizontally with steel plates 12 into a plurality of floors or parking rooms, on which a car can be parked separately moving in the arrow direction in the figures. There is a top steel plate 13 placed horizontally at the top of the parking frame 1 and the lowest room without a steel plate of the parking frame 1 cannot be used for parking; when the parking frame 1 is raised up to the highest position, said lowest room, impossible to be raised up the ground surface, is still kept within the stable frame 2 for maintaining the parking frame straight up safety. The two side horizontal beams 16 facing opposite to each other are provided separately with an inward recess 14 for two wire ropes 24 to pass by up and down. One ends of said wire ropes 24 are fastened at fastening holes 15 at the lowest beam 16. After a car moves in any of the floors, the right rear wheel and the left front wheel can be separately hampered by an anti-sliding bar 31 for preventing the car from sliding away as shown in Figure 5. Next, the stable frame 2 is also an oblong vertical frame made up of steel posts 21 and horizontal steel beams 26 connected between said posts 21 at an equal distance. Motors 22 separately set on the top two sides opposite to each other of said stable frame 2 combined with reducing gears 23 can revolve shafts which wind up and down wire ropes 24; one ends of said wire ropes 24 are fixed on said shafts and the others at the fastening holes 15 so that the parking frame 1 can be raised up and down through the function of the wire ropes wound on the shafts rotated by said reduction gears 23 and said motors 22. There are buffer springs 25 set at each bottom corner of the stable frame 2 for receiving the parking frame 1 when it moves down for preventing both the frames 1 and 2 from vibration caused by their direct mutual touch. In order to enable the parking frame 1 to rise up and down smoothly and steadily inside the stable frame 2, pulley sets 4 are separately provided at the inside surface of the upper part of the stable frame 2 as shown in Figures 1 and 4. Said pulley sets include two pulleys 41 set separately at one ends of two levers 42, the other ends of said levers 42 combined with a T-shaped bolt 43, said T-shaped bolt 43 protruding out of the cover of the pulley sets 4 and being screwed by a nut 44 at its end. Said levers 4 are pivotally set at their position with pivots 45 midway so that in case the nut 45 is screwed tightly against the T-shaped bolt 43, the levers 42 moved by the T-shaped bolt 43 can force the pulleys 41 to push against the vertical posts 11 of the parking frame 1 maintaining the up or down movement of said frame 1 smoothly operated. The anti-sliding device 3 as shown in Figure 5 is used for preventing a car from moving off the parked position after the car is parked on one of the floors. Said anti-sliding device 3 comprises a cylinder 32 and a shaft 33 contained vertically in said cylinder 32 and penetrating through the center of a stable disc 34 horizontally set in said cylinder 32, and a turning wheel 35 and a gear wheel 36 separately fixed at the top end and the bottom end of thesshaft 33, said turning wheel 35 provided with a handle 37 which can be made to stand up for turning said wheel 35 or lie down sticking in one of the notches 38 set around the top edge of the cylinder 32 to prevent said wheel 35 from rotating further. The gear wheel 36 engages with another gear wheel 39 which is welded together with the anti-sliding bar 31 so that said bar 31 can be turned for about 90 degrees crosswise to a car wheel when the gear wheel 39 is rotated by the turning wheel 35. Next, Figures 2 and 3 show a practical example of this parking station using only one set of parking frame 1 and one set of the stable frame assembled together, and when said parking frame 1 is pulled up to let one of the steel plates 12 or the floors become even with the ground surface, the car parked on said plate 12 can be driven out of the parking frame 1. Figure 6 shows a practical example of this parking station using a plurality set of the parking frames 1 and the stable frames continuously connected together and it is easily understood that both the frames 1 and 2 can be constructed connecting in the lateral or the lengthwise direction, and the empty spaces between the frames 2 are only needed to fill in with concrete walls and the tops are only needed to be covered with steel plates. In this example each parking frame 1 is always contained and can be lowered down to the bottom in the stable frame 2 and then all of the top plates 13 of the parking frames 1 make up a drive-way for cars to park in or to drive out of the station. Only one of the parking frames 1 where a car is to be parked in or to be driven out should be raised up to the level of the ground, and the car can be parked therein with the handles 37 of the anti-sliding device 3 operated to stop the car wheels or driven out there with said device 3 operated to make the anti-sliding bars 31 to leave off the car wheels. Figure 8 shows this parking station is constructed in the traffic island, making use of the narrow long characteristic of the land for solving the parking problem. Besides, Figure 9 shows that this parking station is constructed in a land of irregular shape for solving the parking problem, too. As this parking station is to be constructed under the ground as shown in Figure 7, a water pool 5 must be provided at the bottom for collecting rain falling therein and a water pump can be used to pump out the water collected in said pool 5. In case of a flood that the pump can not manage, the whole frame 1 can be raised up lest the cars parked therein be flooded in. In general, this parking station in accordance with the present invention has a main feature that no drive-way is necessary for a car to drive in or out this station, as the top plates not only make up a drive-way but serve for cars to park, and a driver does not have to walk a far way for parking in or driving out. Therefore, a piece of land can be utilized as most as possible in parking cars if this parking station is used. The swift movability of cars can be attained, and the steel frames can be moved to other spot by taking to pieces without breaking to change the use of the land.
