Application December 20, 1954, Serial No. 476,364 4 Claims. or. 21416.1)

This invention relates to new and useful improvements in parking and storage garages for'motor vehicles.

More particularly, the present invention proposes the construction of an improved underground parking and storage garage which can be built upon a small lot in business and other congested areas to handle as a commercial garage a large number of vehicles with a minimum of personnel.

As a further object, the present invention proposes forming the underground garage so that it can be built under factories and apartment houses for operation as a self-service unit by the vehicle drivers themselves.

Still further, the present invention proposes constructing the arage with a surface apron having an elevator shaft frame extending therefrom vertically into the ground and an elevator in the frame with floors radiating from the frame having means thereon to move vehicles t and onto the elevator.

Another object of the present invention proposes forming the garage with a plurality of vehicle holding pallets and with means to hold one of the pallets over the elevator shaft frame to cover the shaft when the elevator is down and to hold a vehicle in position to be loaded on the elevator when the elevator is up.

A further object of the invention proposes constructing the garage with means to remove the shaft frame covering pallet when the elevator rises loaded with a pallet and vehicle or vehicles.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel feat res of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 11 is a fragmentary perspective view of an indicator board with a lamp for each parking floor electrically connected with one of the parking floor switches shown in Fi g. 9.

Referring more particularly to the drawings, the parking garage of the present invention has a surface apron 15 with an elevator shaft frame 16 extending from the apron vertically into the ground.

An elevator 17 adapted to hold one or more vehicles 18 is movably mounted in the frame 16. While elevator 17 may be of any well-known type, in the example shown elevator 17 has an elevator moving means in the form of a hydraulic shaft 19 which fits in hydraulic cylinder 20 supplied with suitable hydraulic fluid at its base by inlet conduit 21 and having an outlet conduit 22. The conduits 21 and 22 are connected with a hydraulic fluid pressure source (not shown) having the usual controls and safety devices (not shown).

A plurality of

underground floors

23, 24, 25 and 26, on the first parking level, 27, 28, 29 and 30 on the next lower parking level and 31, 32, 33 and 34 on the lowermost parking level radiate from the elevator shaft frame 3.6. The parking floors may be so spaced that no two adjacent floors are more apart vertically than slightly more than the height of a vehicle 18. As many floors may be provided as desired and as the terrain permits.

Vehicle transferring'means is provided on each floor to move vehicles to and from the elevator. Such transferring means in the example shown is a hydraulic cylinder 35 mounted behind the end wall 35 of each floor with a hydraulic piston rod 37 slidably mounted in the piston rod and an electromagnet head 38 on the piston rod. Each cylinder 35 may be supplied with hydraulic fluid through

spaced conduits

39 and 43 to move the piston rod forward or retract it as desired.

Each electromagnet head 38 is connected by Wires 41 and 42 in cable 43 to an electric power source through conventional switches and controls. Each cable 43 is wound upon a reel 44 spring biased by spring 45 and mounted in the front end of one of the cylinders 35.

A plurality of metal plates or vehicle holding pallets 46 are provided with a stack of these pallets disposed in a bin 47 at one side of the elevator shaft frame. The electromagnet heads 38, when energized, are adapted to hold onto one edge of a pallet 46 to move that pallet oil and onto the elevator when a vehicle is on the pallet. Preferably one side of each pallet, the top, 43, should be rough to hold a vehicle and prevent it rolling thereon and the other side, the bottom, '49, smooth to slide easily for moving the pallet.

Pallet holding members 59 are provided adjacent the apron to hold one of the pallets 46 over the elevator shaft structure for a vehicle to be moved on and off the pallet. Members 56 are slidably and retractably mounted with springs 51 to bias them normally into their pallet holding position. A cable 52 is connected to one end of each pallet holding member 59 to retract that member. The cables 52

encircle pulleys

53, 54 and 55 and are secured to the bottom of the elevator so that when the elevator rises to the top of the shaft, the members 53 will be retracted and the pallet 4:; held by them and on which a vehicle 18 is parked will be free to rest on the elevator.

A pallet withdrawing hydraulic cylinder 56 and piston rod 57 is provided adjacent the apron and a recess 58 is provided across from the electromagnet head 59 of the piston rod 57 so that a pallet 46 may slidably be withdrawn from the spaced pallet holding members when the elevator approaches the apron with a pallet and vehicle on it. Switch means (not shown) may be provided operativelyfto connect the pallet withdrawing cylinder, piston rod and electromagnetic head with the elevator to operate the Withdrawing means when the elevator ap proaches the apron loaded.

A hydraulic cylinder 69 is provided adjacent the pallet bin 47 with a piston rod 61 to move the bottom pallet from the bin onto the pallet holding members 50. The hydraulic fluid conduits 62' and63 of cylinder 63 may be operatively connected with the elevator to be operated by the lowering of the elevator as shown in Fig. 3.

A control board 64 is mounted on the bin 4"? so that the driver of a vehicle may park his vehicle himself.

on the elevator, and pallet withdrawing means adjacent the apron slidably to withdraw an empty pallet from the pallet holding means, and means operatively connecting the pallet withdrawing means with the elevator to operate said pallet withdrawing means when the elevator approaches the apron with a pallet and vehicle on the elevator.

2. An underground parking and storage garage comprising a ground level surface apron, an elevator shaft Sutiable controls are provided on the board 64 connected 7 to the various hydraulic elements. A lamp panel or indicator board 65 is also provided with a lamp 65' corresponding to each parking floor each lamp being connected to an electric source (not shown) through a floor switch 66. Each floor switch 6-6 consists of a detent but ton 67 biased by a spring 63 away from a switch blade 69.; The blade 69 is connected atone end pivotally with a terminal 70 and a second switch terminal 71 is located beneath the other end of the blade. A spring 72 normally biases the blade away from terminal 71. A pallet 46 sliding onto the floor will press in the detent button and connect the two switch terminals to light the lamp for that floor on the board 65.

To operate the underground garage, the driver of a vehicle parks it on the pallet which normally covers the elevator shaft. He then gets out of the car and presses the elevator starting button on the control panel. When the elevator rises to the top of the shaft, the finger-like members Ell retract depositing the pallet and vehicle on the elevator. The operator then chooses an'empty floor, as shown by the lamps, and presses the elevator button for that floor. When the elevator reaches that floor it stops and the hydraulic cylinder for that floor is energized to move the piston rod forward to contact the pallet with its electromagnet head. This head is then energized and the cylinder fluid is reversed to retract the piston rod dragging the pallet and vehicle onto the parking floor. Meanwhile, the cylinder and piston rod adjacent the pallet bin has moved another pallet over the elevator shaft opening.

When a loaded elevator rises, the piston rod 57 of cylinder 56 moves the empty pallet covering the elevator shaft into the recess 58 from whence it can be removed by the electromagnet head of piston rod 57 when desired. All of the mechanical, hydraulic and electrical elements maybe operatively interconnected for automatic or semiautomatic operation.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit'myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
