FIG. 9 is an electrical circuit diagram of a spring plate opening/closing device that protects a DC motor and reduces power consumption of a storage battery.

In the figure, 48 is the armature of the DC motor for opening and closing the spring plate, 49 is the field coil of the same motor, 50 is a normally open relay contact for lowering the spring plate, 51 is a normally closed relay contact for lowering the spring plate, and 52 is a relay contact for lowering the spring plate. A normally open relay contact for the valve on the splash plate, 53 a normally closed relay contact for lowering the splash plate, 54 a lowering push button, 55 a rising push button, and 56 open when the splash plate is lowered to its lowest position. 57 is a limit switch that opens when the spring plate is raised to the highest level, 58 is a relay 50
59 is a non-contact timer, 6
0 is a relay coil, 61 is a normally closed relay contact operated by the relay coil 60, and 63 is a relay coil that operates the relay 52.

Therefore, when the push button 54 is pressed to lower the splash plate, the limit switch 56 is connected, so the relay contact 61
The relay coil 58 operates, the contact 50 operates, and the contact 5
3 is normally closed, so the DC motor works and the splash plate begins to descend.

Then, after a certain period of time, the non-contact timer 59 works, current flows through the relay coil 60, and the contact 61 stops working, so the relay coil 58 does not work, so the relay contact 50 does not work, so the motor stops, and after that, It descends due to the weight of the splash plate.

When the splash plate is at its lowest position, the limit switch 56 is open.
Even if the lowering push button 54 is operated thereafter, the electric motor will not be driven.

Further, when the splash plate is to be raised, when the push button 55 is pressed, the relay coil 63 is operated and the relay contacts 52 and 51 are connected, so that the electric motor is activated to raise the splash plate.

When the splash plate reaches its highest position, the limit switch 57 opens and the motor stops.

As mentioned above, since a timer is used, the splash plate will descend under its own weight after a certain period of time, so even if there is a level difference between the elevator platform and the parking floor, the motor will not continue to drive.
Electric motors are protected.

Furthermore, since the time for driving the electric motor is short, the power consumption of the storage battery can be reduced.

As shown in FIG. 1, operation panels 62 a and 62 b are provided on both sides of the lifting platform 7, so that whether the vehicle C is carried forward or backward to the lifting platform 7,
The driver can operate the operation panel 62a or 62b while sitting in the seat.

The layout of the switch buttons on the operation panel is designed as shown in FIG.

Furthermore, all of the above-mentioned parts are assembled so that they can be disassembled and reassembled by tightening bolts, so that the parking facility can be transported and easily assembled for use in various gathering places.

Next, the parking method in the above embodiment will be explained.

First, the car C is carried onto the elevator platform 7 which is at its lowering limit with the splash plate 30 open, and while sitting on the seat, operate the operation panel 62a or 62b to close the splash plate 30, and The frame 6 is moved horizontally and the lifting platform 7 is raised, the spring plate 30 is opened, and the car C is carried into a desired car storage compartment. and return to the original position.

Of course, the method for taking out the parked car C can be carried out by following the above procedure in reverse.

As shown in the examples above, the multilevel parking facility of the present invention is
A parking shelf that has a car storage compartment in a double-layer, double-row structure and is erected on the floor or ground so that the floor or ground is also a car storage compartment, and a parking shelf that is erected on the floor or ground in front of this parking shelf. a base frame, a car lifting platform capable of being lifted and lowered within the base frame between the double-layered car storage compartments of the parking shelf and having a loading/unloading entrance at the front and rear ends, and a lifting guide device and a lifting drive device thereof. and a traverse drive device for traversing the base frame in the left-right direction parallel to the front of the parking shelf on the floor or ground, and the elevating drive device includes a lift cylinder attached to the base frame and an upper end thereof. The traverse drive device is installed in the traverse direction with its lower part recessed into the floor or ground. It consists of a transverse rail, a guide roller provided at the center of the lower part of the base frame so as to fit into the rail, and drivable tire-type wheels provided at the lower four corners of the base frame. The guide device consists of outer rollers that are pivotally supported at the four corners of the vehicle elevator via front and rear shafts so as to roll on the left and right inner end surfaces of the four outer columns of the base frame, and outer rollers that are mounted on the left and right sides of the base frame. Four groove-shaped rails are installed vertically in the center, two of which are adjacent to each other in the front and rear, and each of which faces left and right. It is composed of four inner rollers on each side, which are pivotally supported on the vehicle elevator platform via left and right shafts so as to roll on the end faces.

Therefore, according to the present invention, the parking shelf has a simple frame structure and a lifting platform for simple lifting and lowering, and can be easily disassembled and reassembled together with the base frame of a simple frame structure.

In addition, in the present invention, even if the car lifting platform is slightly tilted to the left or right, it can be supported by the outer rollers, and the front and rear directions, which tend to tilt when loading and unloading the car, are supported by the four inner rollers on each side. The vertical deviation between the inner rollers is extremely small, and it is possible to prevent friction between the inner rollers and the inner support pillars from increasing, allowing the vehicle elevator to be guided up and down extremely smoothly.

Further, in the present invention, a car storage compartment is provided on the floor or ground below the parking shelf, the car elevating platform is supported by a lift cylinder and a bench so as to be able to rise and fall on the base frame, and the traversing rail is recessed into the floor or ground at its lower part. Since the car is laid in the same condition, it is not only necessary to pass through the car lifting platform 7 to transport the car to the car storage compartment on the lowest level, but also to directly transport the car across the horizontal rail when the lifting platform 7 is used. It can be self-propelled and stored in the compartment.

Further, the traverse drive device includes a traverse rail laid on the floor or the ground, a guide roller provided at the center of the lower part of the base frame so as to fit into the rail, and tire-type wheels provided at the lower four corners of the base frame.
