  A preferred embodiment of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

  FIG. 2 (A) is a schematic diagram showing the configuration of the two-stage parking device 10 according to the embodiment of the present invention.

  The two-stage parking apparatus 10 has n pallet spaces Sp in which pallets can be arranged in the same horizontal direction (n is an integer of 2 or 3 or more, but in FIG. 2A, n = 3). The floors provided adjacent to each other have a structure in which a plurality of levels (four levels in FIG. 2A) are provided vertically at the same horizontal position.

  On each floor other than the lowest floor, (n-1) pieces (two in FIG. 2A) that can move horizontally between adjacent pallet spaces Sp and can move up and down between the first floor. A pallet 3a is provided.

  On the lowest floor, (n-1) pallets 3b that can move horizontally between adjacent pallet spaces Sp are provided. On the lowest floor, any one of the n pallet spaces Sp is used as the storage space Se for the pallet space Sp. The vehicle 1 enters / exits only from this entry / exit space Se. In FIG. 2A, the vehicle 1 gets on the pallet 3b located in the loading / unloading space Se or gets out of the pallet 3b located in the loading / unloading space Se in a direction perpendicular to the paper surface.

  Preferably, on the lowest floor, three or more pallet spaces Sp are provided adjacent to each other in the same horizontal direction. In this case, preferably, among the three or more pallet spaces Sp on the lowermost floor, one pallet space Sp located in the middle is used as the loading / unloading space Se. That is, the entry / exit space Se and the pallet space Sp are adjacent to each other on both sides of the entry / exit space Se.

  Each pallet 3a on each floor other than the lowest floor moves horizontally and moves up and down by the following configuration.

  An elevating and traversing device 5 is provided for each pallet 3a on each floor other than the lowest floor. Each lifting / lowering traversing device 5 has a lifting / lowering device 7 for lifting / lowering the corresponding pallet 3a, and a traversing frame 9 provided with the lifting / lowering device 7 and movable in the horizontal direction between adjacent pallet spaces Sp. Each lifting device 7 has a linear body 11 that suspends the corresponding pallet 3a, and lowers the pallet 3a by feeding the linear body 11 downward from the traversing frame 9 side, thereby moving the linear body 11 to the traversing frame 9 side. And a driving device 13 that raises the pallet 3a by moving it upward.

  With the above-described configuration, each pallet 3a on each floor other than the lowest floor is moved to the pallet space Sp directly above the warehousing space Se by the traversing frame 9, and is moved into the warehousing space Se by the lifting device 7. When the pallet 3a is positioned in the loading / unloading space Se, the vehicle 1 can enter the pallet 3a or the vehicle 1 can enter the pallet 3a. In FIG. 2A, the vehicle 1 gets on the pallet 3a located in the loading / unloading space Se or gets out of the pallet 3a located in the loading / unloading space Se in a direction perpendicular to the paper surface.

  According to the two-stage parking apparatus 10 described above, the following effects can be obtained.

In the present embodiment, on the lowest floor, among the plurality of pallet spaces Sp, only one pallet space Sp located at the middle part or the end part is used as the loading / unloading space Se (hereinafter the same), and the lowest pallet 3b. The pallet 3a on each floor other than the lowest floor, including the top floor, can be moved horizontally and moved up and down, so that the vehicle can always be moved from only the one entry / exit space Se on the bottom floor. 1 can be put in and out. In this case, as shown in the schematic diagram of FIG. 2 (A), the interval W (two locations in FIG. 2 (A)) between the entry / exit space Se and the pallet space Sp adjacent thereto is changed to the conventional interval W0 ( By making it larger, the vehicle 1 can always be loaded and unloaded from a wide space.
On the other hand, in the conventional configuration, as shown in the schematic diagram of FIG. 2 (B), each pallet space Sp on the first floor becomes an entry / exit space. Therefore, as in FIG. In order to load and unload the vehicle 1 from a wide space, it is necessary to increase the space width W at four locations.
Therefore, in this embodiment, since a wide space can be secured by increasing only the interval between the entry / exit space Se and the pallet space Sp adjacent thereto, compared to the conventional case of FIG. Even if a wide space is provided, the overall size of the two-stage parking apparatus 10 can be suppressed.
Therefore, while suppressing the overall size of the two-stage parking apparatus 10, the entry and exit of the vehicle 1 from the pallets 3a and 3b and the passage of people by the side of the vehicle 1 loaded on the pallets 3a and 3b are made convenient. It becomes possible.

In the embodiment of the present invention, as in the example of FIG. 2 (A), the vehicle 1 on the pallet 3a in the entry / exit space Se (hereinafter referred to as the first target vehicle 1) and the pallet adjacent to the entry / exit space Se. The distance Wp (hereinafter referred to as the passage width) with the vehicle 1 (hereinafter referred to as the second target vehicle 1) on the pallet 3b that is positioned in the space Sp and is waiting for delivery is always larger than 50 cm. The positional relationship between the delivery space Se and the pallet space Sp adjacent thereto is set. That is, a space having a dimension larger than 50 cm is secured between the first target vehicle 1 and the second target vehicle 1 in the width direction of the pallets 3a and 3b as a space through which a person can pass. The passage width Wp is an interval between the first target vehicle 1 and the second target vehicle 1 excluding the door mirrors of the first target vehicle 1 and the second target vehicle 1, or in the first target vehicle 1. It may be an interval between the door mirror on the second target vehicle 1 side and the door mirror on the first target vehicle 1 side in the second target vehicle 1.
The passage width Wp varies depending on the position in the width direction where the first target vehicle 1 gets on the pallet 3a and the position in the width direction where the second target vehicle 1 gets on the pallet 3b. By making the minimum value in the numerical range of the changing passage width Wp larger than 50 cm, the passage width Wp is always larger than 50 cm as described above. The first target vehicle 1 and the second target vehicle 1 are the vehicles 1 having the largest width among the vehicles 1 that can be stored in the parking device 10. Here, the vehicle 1 that can be stored means the vehicle 1 that can be physically stored by the structure of the parking device 10 and the vehicle 1, or the size range determined by the operator or administrator of the parking device 10. It means the vehicle 1 having the inside dimensions.

  In the present application, the width direction means a horizontal direction (left and right direction in FIG. 2A) perpendicular to the direction in which the vehicle 1 gets into the pallets 3a and 3b (vertical direction of the pallets 3a and 3b), or the vehicle 1 is in the pallet 3a. 3b means a horizontal direction (left and right direction in FIG. 2A) orthogonal to the direction of getting out from 3b (vertical direction of pallets 3a and 3b).
