BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story parking garage with a transport device, and more particularly to a simplified parking storage rack structure for an automobile.

[0002]

2. Description of the Related Art Conventionally, a large-scale multi-story parking lot with a transfer device generally includes a plurality of storage racks for car parking provided on a plurality of floors, an elevator, an entrance stage for passing the automobile to the elevator, and an automobile. And a transport carriage that transports the automobile on each floor. However, there is a case where an elevating and traveling transport device (stacker device) in which an elevator and a transport trolley are integrated is applied.

In a pallet-type multilevel parking lot, a car is transported on a pallet and stored in a storage rack as it is. Therefore, a roller conveyor is provided in each of an elevator, a transport trolley, and each storage rack. In addition, when transferring an automobile between an entrance stage or an exit stage and an elevator, an elevator and a transport vehicle, or between a transport vehicle and a storage rack, the vehicle is transferred via a vehicle width direction movement. In a slat conveyor type multi-story parking lot, slat conveyors for transferring vehicles in the vehicle width direction are usually provided on the entrance stage, exit stage, elevator, transport trolley, and each storage rack, and usually, elevators and transport trolleys are provided. In some cases, a vertical conveyor means for transporting the vehicle in the longitudinal direction may be provided. In some cases, the drive motor for the slat conveyor of each storage rack is omitted, and the drive force is transmitted from the drive gear on the side of the transport trolley to the driven gear of the slat conveyor of the storage rack. For example, Japanese Unexamined Patent Publication No. 6-18565 describes a slat conveyor type multi-story parking lot provided with a staying stage adjacent to a storage stage, a staying stage adjacent to an unloading stage, and the like.

[0004] In a comb-shaped rack type multi-story parking garage, a comb-shaped rack is provided for each of the transport trolley, the elevator, and each storage rack, and at least the comb-shaped rack is moved up and down a predetermined stroke in the transport trolley. An extension mechanism is provided for extending the lift mechanism and the comb-shaped rack by a predetermined stroke in the vehicle width direction. However, in the multi-story parking lot of this system, the slat conveyor cannot be applied to the entrance stage and the exit stage. For example, JP-A-5-22
Japanese Patent No. 2859 discloses a comb-shaped rack provided on a loading / unloading table as a loading / unloading stage, a comb-shaped rack, a lift mechanism, a telescopic mechanism, etc. provided on a stacker as an elevator / transportation carriage. A multi-story parking garage with a comb-toothed rack type transfer device provided with a toothed rack is described.

[0005]

In the pallet-type multi-story parking garage, a large number of storage racks are provided with idle-type roller conveyors, so that the equipment cost is high, and the work of returning a large number of pallets to the storage racks.

However, since a movable comb-teeth rack that is driven up and down by a lift mechanism and expands and contracts by an expansion and contraction mechanism is attached to the elevator and stacker, the conveyor that transfers vehicles to and from the slat conveyor to the elevator and stacker It is almost difficult to add a mechanism. As a result, there is a problem that an optimal slat conveyor cannot be applied to the entrance stage and the exit stage in terms of safety when a passenger gets on and off.

In addition, the movable comb-tooth rack attached to the carrier has a higher height than the upper surface of the fixed comb-tooth rack in order to avoid interference with the fixed comb-tooth rack of the storage rack. A lift mechanism moves up and down by a lift mechanism over a rising position that is positioned as a whole and a lowering position that is positioned lower than the lower surface of the fixed comb-shaped rack as a whole, and transfers the vehicle to the storage rack. When moving, the telescopic mechanism is extended while being held at the raised position, and then the movable comb-teeth rack is moved to the lowered position and the telescopic mechanism is driven in and out. Becomes larger,
Since the height of the storage rack from the floor of the comb-tooth rack increases, the height of the storage rack on each floor increases, the volume efficiency of the parking lot decreases, and the parking lot as a whole becomes larger. There are also problems.

An object of the present invention is advantageous in terms of equipment costs and running costs for a large number of storage racks, and a slat conveyor or the like having a substantially flat upper surface and capable of allowing human walking can be applied to the entrance stage and the exit stage.
