Abstract

A mechanical automobile parking facility with auto parking pallets, in which a vehicle is driven onto an auto parking pallet which is moved with the vehicle thereon to a predetermined space inside the facility. In order to guarantee reliable and abrasion free parking, a driving unit on rails is included whereby the driving unit with the auto parking pallet lying thereon, proceeds along a parking aisle and the auto parking pallet is pushed sideways from the driving unit by telescopic cylinders over glide rails into a free parking space, or conversely the auto parking pallet is taken from there onto the driving unit.

Claims

1. A mechanical vehicle parking facility, comprising:

a parking structure having at least one parking level, the parking level having an aisle extending in a first, longitudinal direction and having opposite sides, and a plurality of parking spaces extending along opposite sides of the aisle;

a running rail extending along each side of the aisle;

each parking space having opposite ends, and having a slide rail at each end of the space extending in a second direction transverse to said longitudinal direction;

a plurality of vehicle parking pallets, each parking pallet being capable of having a vehicle driven onto it and having support means for supporting a vehicle thereon;

a driving unit capable of supporting a parking pallet with a vehicle thereon;

the driving unit being movable on said running rails along said aisle;

the driving unit including hydraulic telescopic cylinders for moving a parking pallet in a direction transverse to said first direction from the driving unit into an adjacent parking space on said slide rails, and in a reverse direction from

said parking space onto said driving unit;

said slide rails supporting a parking pallet and vehicle in a respective parking space;

the driving unit having a lifting platform assembly for supporting a parking pallet, the lifting platform assembly including locking means for locking the parking pallet onto the driving unit, and a lifting device for lifting the platform assembly with the parking pallet and vehicle thereon;

the parking structure having an entrance position for entry of vehicles into the facility;

a turntable arranged above the entrance position of said structure, the turntable including a rotary drive device for rotating the turntable; and

the turntable having an opening for receiving a parking pallet with a vehicle thereon in response to the pallet being raised by the lifting device, and a releasable locking device for releasably locking the parking pallet in said opening, whereby the parking pallet and vehicle can be rotated into a selected orientation for driving into or out of the parking facility.

2. The facility as claimed in claim 1, wherein the parking structure has a plurality of levels, and each level has at least one aisle and a plurality of parking spaces along said aisle.

3. The facility as claimed in claim 1, wherein the lifting device comprises vertical carriers of U-shaped cross-section, the lifting platform assembly having rollers riding in the U-shaped carriers, and telescopic cylinder drive means for moving a supported pallet in a vertical direction.

4. The facility as claimed in claim 1, wherein each pallet has an upper surface for supporting a vehicle and a lower surface, and opposite ends, the pallet further having a downwardly directed, U-shaped channel on its lower surface adjacent each end of the pallet, and a respective hydraulic telescoping cylinder is arranged in each U-shaped channel when the pallet is supported on the driving unit, each telescoping cylinder having a locking bolt for extending transversely of the cylinder, each U-shaped channel having opposite sides and holes along at least one side, and said locking bolts being releasably engageable in a selected hole in the side of the respective channel.

5. The facility as claimed in claim 4, wherein the turntable has four magnetic locks arranged for releasable engagement in the holes in said pallet channels.

6. The facility as claimed in claim 1, wherein each pallet has at least two water drainage channels for draining water from the pallet.

7. The facility as claimed in claim 1, wherein the locking means for locking a pallet onto the driving unit comprises magnetic bolts, each pallet having holes for alignment with said bolts, and said bolts being movable into an extended position in said holes to lock the pallet on said driving unit.

8. The facility as claimed in claim 1, wherein the driving unit has drive means including a hydraulic motor, three axles, and a drive chain, the drive chain drivably interconnecting two of the axles, and the drive means is operable through the drive chain for driving said two axles and thereby said driving unit.

9. The facility as claimed in claim 1, wherein each pallet has a pair of spaced grooves for engagement on said slide rails at opposite ends of a respective parking space when said pallet is driven into said space.
