Further, conveyance rails (not shown) are provided on the lower surface 8B in the depth direction D (longitudinal direction) and the device width direction W (lateral direction) of the tray 8, and the tray 8 is supported by a transfer roller 52 and a drive roller 46 described later and can be conveyed in the longitudinal direction or the lateral direction. Hereinafter, the level of the upper surface 8A of the tray 8 is also referred to as the boarding surface.

[0032] [Loading / Unloading Section] As shown in Fig. 1, in the apparatus width direction W, the boarding and alighting chamber 2 and the elevating chamber 4 are arranged adjacent to each other in the warehousing unit 1. Specifically, the mechanical parking apparatus in the present embodiment is of a type in which the elevating chamber 4, which is a part for elevating and transporting the vehicle M between the storage unit 6, and the boarding and alighting chamber 2, where the vehicle M is placed on the tray 8 and the user boards and alights from the vehicle M and the user enters and exits the chamber, are separately arranged. Since the warehousing unit 1 and the warehousing and unloading unit 11 have the same configuration as the warehousing and unloading unit, the warehousing unit 1 will be described here.

[0033] 〔Boarding and alighting chamber〕 As shown in Figs. 1 to 3, in the boarding and alighting chamber 2, the tray 8 is arranged at the central part in plan view, and the movable deck 10 is arranged adjacent to the side of the elevating chamber 4 in the apparatus width direction W of the tray 8, which will be described later. Further, the boarding and alighting chamber 2 has an entrance / exit door 20 for the vehicle M to enter facing the boarding surface of the tray 8, a partition door 22 for partitioning the boarding and alighting chamber 2 and the elevating chamber 4, and an operation panel 28 for the user to operate the mechanical parking apparatus. Further, a floor serving as a boarding surface corresponding to the upper surface 8A of the tray 8 into which the vehicle M enters and a pit 24 having a depth downward in the apparatus height direction H from the floor are formed. In the present embodiment, as an example, when the floor height of the boarding and alighting chamber 2 is low, or when there are obstacles such as building beams, air conditioning equipment, or fire extinguishing equipment around the entrance / exit door 20, the entrance / exit door 20 is composed of three elevating doors so that it can be installed. However, according to the degree of obstacles on the building side, it may be composed of two or four or more elevating doors, and of course, it may also be composed of two or three or more side-opening doors.

[0034] Further, as shown in FIGS. 3 and 4, in the boarding and alighting chamber 2, two trays 8 are arranged at intervals in the apparatus height direction H. Specifically, in the boarding and alighting chamber 2, an upper tray 8 whose upper surface 8A of the tray 8 is located on the boarding surface is supported by a conveying means 30 having support rollers 32 that can be conveyed between the boarding and alighting chamber 2 and the elevating chamber 4 and is arranged at both longitudinal ends of the tray 8. Also, on the floor surface of the pit 24, which is the surface facing upward in the apparatus height direction H of the pit 24, a plurality of transfer devices 50 having transfer rollers 52 for supporting transfer rails are arranged at intervals in the conveying direction of the tray 8 (the apparatus width direction W in this embodiment) at positions corresponding to two transfer rails (not shown) provided on the lower surface 8B of the tray 8.

[0035] Further, as shown in FIG. 4, the pit 24 is provided with a lifting device 26 for lifting and lowering the tray 8 between the position of the upper tray 8 and the position of the lower tray 8. In this embodiment, as an example, the lifting device 26 includes a support base 26 on which the tray 8 is placed and a pantograph-type lifting device (not shown) for lifting and lowering the support base 26.

[0036] (Conveying means) As shown in FIGS. 4 and 5, the conveying means 30 is a device that supports both longitudinal ends of the upper tray 8 in the longitudinal direction in the boarding and alighting chamber 2 and both longitudinal ends of the movable deck 10, and horizontally moves the tray 8 between the boarding and alighting chamber 2 and the elevator 42. Further, the conveying means 30 includes a plurality of support rollers 32 that pivot horizontally between a support position for supporting the tray 8 and the movable deck 10 and a retracted position where the tray 8 and the movable deck 10 are not supported, a link mechanism 34 connected to each of the plurality of support rollers 32 for synchronously pivoting each support roller 32, a conveying device 36 for horizontally conveying the tray 8, and fixed rollers 32A that are fixed at positions provided between the movable deck 10 and the elevator 42 and rotatably support both longitudinal ends of the tray 8 so as to be conveyable. Here, the link mechanism 34 is an example of a pivoting mechanism.

[0037] The plurality of support rollers 32 provided on the conveying means 30 specifically support the lower surfaces 8B at both longitudinal ends of the tray 8, and rotate in the direction in which the tray 8 is conveyed between the boarding and alighting chamber 2 and a lift 42 (to be described later) arranged in the elevating chamber 4 (the direction of the device width direction W), i.e., the support position, and are horizontally pivotally driven between the retracted position where they are retracted from the lower surface 8B of the tray 8 and the retracted position where the tray 8 can be lifted between the boarding surface of the boarding and alighting chamber 2 and a transfer device 50 (to be described later) installed on the floor of the pit 24. In the present embodiment, the support roller 32 is rotatably provided on a swing arm that is supported by a rotation axis (not shown) facing the device height direction H and is provided to swing in the horizontal direction. Also, each support roller 32 is configured to freely rotate as the tray 8 moves without being driven.

[0038] The support roller 32 has a link mechanism 34 for swinging between the support position and the retracted position. The link mechanism 34 is driven by a driving means (not shown) to switch the support roller 32 between the support position for supporting the tray 8 and the retracted position for not supporting the tray 8.

[0039] As shown in FIG. 5, the conveying device 36 includes conveying rollers 38 that contact both longitudinal ends of the tray 8 and convey the tray 8 in the short side direction of the tray 8, a driving device (not shown) that rotationally drives the conveying rollers 38, and a retracting device (not shown) that retracts and extends the conveying rollers 38 between a contact position where they contact the tray 8 and a separated position where they are separated from the tray 8. The conveying device 36 conveys the tray 8 between the boarding and alighting chamber 2 and the elevating chamber 4 by bringing the conveying rollers 38 into contact with the tray 8 and driving them. Also, the conveying device 36 enables the tray 8 to be lifted between an upper tray position and a lower tray position in the boarding and alighting chamber 2 by retracting the conveying rollers 38 to the separated position where they are separated from the tray 8.

[0040] (Transfer device) As shown in FIGS. 4 and 5, a plurality of transfer devices 50 are installed on the floor surface of the pit 24 of the boarding and alighting chamber 2 and on the transfer frame 40A provided on the side of the boarding and alighting chamber 2 of the lifting frame 40 rising from the storage chamber 6 in the lifting chamber 4. In the boarding and alighting chamber 2, the transfer device 50 supports the trays 8 that are stacked with a space therebetween below the tray 8 arranged on the boarding surface by the transfer rollers 52 that can be rotated and conveyed. Specifically, the transfer device 50 is arranged at positions corresponding to two conveying rails (not shown) provided along the short side direction of the tray 8 with a space therebetween in the longitudinal direction on the lower surface 8B of the tray 8.

[0041] The transfer roller 52 is supported by a rotating shaft along the depth direction D of the device and is rotatably fixed, and is arranged so as to be able to convey the tray 8 between the boarding and alighting chamber 2 and the lift 42 of the lifting chamber 4. Thereby, the tray 8 is supported by the transfer roller 52 and can be conveyed between the boarding and alighting chamber 2 and the lift 42 arranged in the lifting chamber 4 below the boarding surface in the boarding and alighting chamber 2. The conveyance of the tray 8 by the transfer roller 52 is allowed to be performed during the loading and unloading operations of the vehicle M in the boarding and alighting chamber 2.

[0042] 〔Lifting Chamber〕 As shown in FIGS. 2, 3, and 5, the lifting chamber 4 is arranged adjacent to the side of the movable deck 10 of the boarding and alighting chamber 2 in the width direction W of the device and communicates with the storage unit 6. The lifting chamber 4 includes four lifting frames 40 rising from the storage device 60 installed in the storage unit 6, a lift 42 supported by a link chain (not shown) on the lifting frame 40 so as to be able to move up and down, a transfer frame 40A provided on the side of the boarding and alighting chamber 2 of the lifting frame 40, and a drive device 49 that drives the link chain so that the lift 42 can move up and down between the lifting chamber 4 and the storage unit 6.

[0043] Also, as shown in FIG. 5, a partition door 22 is provided on the wall separating the boarding and alighting chamber 2 and the elevating chamber 4 so as to be openable and closable along the device height direction H. In this embodiment, as an example, the partition door 22 is a three-leaf door so that it can be installed even when the floor height of the elevating chamber 4 is low or there are obstacles such as building beams directly above the partition door 22. In this embodiment, as an example, the partition door 22 is a three-leaf elevating door so that it can be installed even when the floor height of the elevating chamber 4 is low or there are obstacles such as building beams, air conditioning equipment, or fire extinguishing equipment around the partition door 22. However, depending on the degree of obstacles on the building side, it may be a two-leaf or four-leaf or more elevating door, and of course, it may also be a two-leaf or three-leaf or more side-opening door.

[0044] (Lift) As shown in FIG. 5, the lift 40 has a vertical and horizontal transfer device 44 for transferring the tray 8 in the directions of the device width direction W and the device depth direction D at the center of the device width direction W of the lift 42. The vertical and horizontal transfer device 44 shown as an example is provided on the lower surface 8B of the tray 8 and is arranged to be horizontally rotated corresponding to two horizontal feed rails provided at intervals along the short side direction of the tray 8 (not shown) and one vertical feed rail provided at the center in the short side direction along the long side direction of the tray 8. This vertical and horizontal transfer device 44 is provided on a turntable that horizontally rotates and supports two drive rollers 46 respectively, and the two turntables are connected to a link mechanism 48 and horizontally rotated synchronously. Here, the lift 42 is an example of an elevator.

[0045] [Configuration of the main part] Here, the configuration of the main part will be described with reference to FIGS. 6 to 13.

[0046] [Movable deck] As shown in FIGS. 1, 3, and 5, the movable deck 10 is arranged between the tray 8 arranged in the boarding and alighting chamber 2 and the elevating chamber 4. The movable deck 10 is formed in a rectangle in plan view, and has an upper surface 10A on which users ride when getting on and off the vehicle M, and an elevating guide member 10D to be described later is provided. Back side10B, a support member 10C provided at both ends in the depth direction D of the apparatus and supported by the support rollers 32 such that the support rollers 32 support it from below in the height direction H of the apparatus, and a lifting guide member 10D in contact with the lifting rollers 16E provided on the lifting member 16C of the lifting means 16 described later. The movable deck 10 is configured such that its upper surface 10A is at the same upper height as the upper surface 8A of the tray 8 that serves as the boarding surface, and when the tray 8 located on the boarding surface is supported by the support rollers 32 and moves between the elevating chambers 4, it can be lifted and lowered between a lower height that does not interfere with the lateral feed rollers 82 and longitudinal feed rollers 84 of the tray 8.

[0047] The movable deck 10 is moved to a position that allows the movement of the tray 8 located above when the tray 8 located above moves between the boarding chamber 2 and the elevating chamber 4, and is moved to a position that allows the movement of the tray 8 located below when the tray 8 located below moves between the boarding chamber 2 and the elevating chamber 4. Specifically, the position on the movable deck 10 that allows the movement of the tray 8 located above is a position below the tray 8 located above, and the position on the movable deck 10 that allows the movement of the tray 8 located below is a position above the tray 8 located below. More specifically, the position on the movable deck 10 that allows the movement of the tray 8 located above is a position below the conveying height L1 of the tray 8 located above, and the position on the movable deck 10 that allows the movement of the tray 8 located below is a position above the conveying height L2 of the tray 8 located below.

[0048] Also, when the movable deck 10 descends, it does not descend below the transfer device 50 having the transfer rollers 52 in the height direction H of the apparatus, that is, it only descends to a position above the conveying height L2 of the tray 8 located below. Therefore, there is no need to provide an opening on the upper surface 10A to avoid interference with the transfer device 50 and an opening / closing lid to close the opening, and the upper surface 10A is a flat plate-like body. Also, although the movable deck 10 is described as a rectangle with one side long and the other side short in plan view in FIG. 5, the movable deck 10 is not limited to a rectangle in plan view and can have other shapes such as a square or a trapezoid.

[0049] [Lifting means] As shown in FIGS. 5 to 8, lifting means 16 for raising and lowering the movable deck 10 are arranged on the floor of the pit 24. The lifting means 16 includes a motor 16H, a drive shaft 16B operatively connected to the motor 16H, and a lifting member 16C having one end fixed to the drive shaft 16B and the other end being a rotatable free end. When the drive shaft 16B is driven by the motor 16H, the free end of the lifting member 16C rotates while supporting the back surface 10B of the movable deck 10, thereby raising and lowering the movable deck 10.

[0050] In the present embodiment, as an example, the lifting means 16 includes a pair of lifting members 16C provided at intervals along one side of the movable deck 10, and the pair of lifting members 16C are fixed to both ends of the drive shaft 16B. Specifically, the lifting means 16 includes a pair of bearings 16A provided on the floor surface of the pit 24 on the side of the back surface 10B of the movable deck 10 and spaced apart in the short side direction, which is one side direction of the movable deck 10. The drive shaft 16B is rotatably supported between the pair of bearings 16A. One end of the lifting member 16C is fixed in a direction perpendicular to the drive shaft 16B at a portion of the drive shaft 16B close to the bearing 16A, and the other end of the lifting member 16C is a free end, and a shaft 16D having an axis parallel to the drive shaft 16B is fixed to the other end. A lifting roller 16E is rotatably provided on the shaft 16D. A gear 16F is fixed to the drive shaft 16B concentrically with the axis of the drive shaft 16B. The gear 16F meshes with a drive gear 16G provided on the motor 16H. Thus, a set of lifting means 16 is configured.

[0051] In the present embodiment, as shown in FIG. 5, two sets of the lifting means 16 are arranged at intervals in the longitudinal direction, which is the direction of the other side of the movable deck 10. The two sets of the lifting means 16 are arranged such that the free ends, which are the other ends of the lifting members 16C, i.e., the sides where the lifting rollers 16E are provided, face each other.

[0052] The free end of the lifting member 16C has a lifting roller 16E that rotatably contacts the back surface 10B of the movable deck 10. Specifically, the lifting roller 16E contacts a lifting guide member 10D provided on the back surface 10B of the movable deck 10.

[0053] Also, a pair of lifting means 16 are provided at intervals in the direction of the other side of the movable deck 10, and the pair of lifting means 16 operate synchronously. Specifically, when the motor 16H is driven, the driving gear 16G rotates, the gear 16F meshing with the driving gear 16G rotates, and the driving shaft 16B rotates. As a result, the lifting member 16C fixed to both ends of the driving shaft 16B rotates about the driving shaft 16B as the turning center. Then, the lifting roller 16E rotatably provided on the free end side of the lifting member 16C contacts the lifting guide member 10D provided on the movable deck 10 to cause the movable deck 10 to move up and down. At this time, the lifting roller 16E relatively moves in the longitudinal direction of the lifting guide member 10D by the turning operation of the lifting member 10C. Details of these operations will be described later.

[0054] 〔Supporting means〕 As shown in FIGS. 9 to 13, the supporting means 31 supports the longitudinal ends of the movable deck 10. As shown in FIG. 5, the supporting means 31 are respectively arranged at both longitudinal ends of the movable deck 10, and the supporting roller 32 described later turns horizontally between a supporting position for respectively supporting both ends of the movable deck 10 and a retracted position where the movable deck 10 is not supported.

[0055] As shown in FIGS. 9 and 14, the support means 31 includes a plurality of pivot shafts 31A fixed to the pits 24 and having an axis in the apparatus height direction H, support rollers 32 rotatably provided via a shaft installed in a direction facing the side of the movable deck 10 above each pivot shaft 31A, an actuator plate 31B fixed below the pivot shaft 31A and on the side opposite to the support roller 32, a rotating plate 31C rotatably provided horizontally on a rotating shaft 31D facing the apparatus height direction H of a drive motor (not shown) disposed between the two pivot shafts 31A, 31A, and a plurality of connecting members 31E that connect the plurality of actuator plates 31B and the rotating plate 31C to form a link mechanism. In the present embodiment, there are three pivot shafts 31A and three support rollers 32 provided on the pivot shafts 31A. FIG. 9 shows a state of supporting the movable deck 10.

[0056] FIG. 10 shows a state in which the support roller 32 of the support means 31 is in a retracted position where it does not support the movable deck 10. As shown in FIG. 10, when the rotating plate 31C is rotated counterclockwise by the counterclockwise rotation of the rotating shaft 31D of a drive motor (not shown), the link mechanism operates to rotate the pivot shaft 31A counterclockwise, so that the support roller 32 provided on the pivot shaft 31A pivots to a position where it retracts from the movable deck 10 and stops. By operating in the opposite direction to this operation, as shown in FIG. 9, the support roller 32 pivots to a support position where it supports the movable deck 10 and stops.

[0057] FIGS. 11 to 13 are views seen from the central portion in the longitudinal direction of the movable deck 10 in the direction of the depth D of the apparatus. FIG. 11 shows a state in which the support roller 32 is stopped while supporting the movable deck 10. FIG. 12 shows a state in which the lifting means 16 operates to support the movable deck 10 while the support roller 32 supports the movable deck 10. FIG. 13 shows a state in which, with the lifting means 16 supporting the movable deck 10, the support roller 32 has pivoted to a retracted position where it retracts from the movable deck 10 and stopped.

[0058] As shown in FIG. 11, the support roller 32 supports the lower surface of a support member 10C fixed to both end portions of the back surface 10B of the movable deck 10. On the lower surface of the support member 10C of the movable deck 10, positioning members 10E for preventing the movable deck 10 from swaying in the apparatus width direction W are provided corresponding to the left and right support rollers 32 in the apparatus width direction W when the support member 32 is located at the support position. In the present embodiment, the positioning member 10E is formed of a plate material and has a positioning surface 10E1 that engages when the support roller 32 pivots to the support position. The positioning surface 10E1 is formed in an arc shape having a radius slightly larger than the outer peripheral radius of the support roller 32 so that the outer peripheral surface of the support roller 32 can engage and disengage. Further, the elevating means 16 shows the state before operation, and the elevating roller 16E provided on the elevating member 16C waits at a position close to the floor of the pit 24.

[0059] Next, as shown in FIG. 12, with the support roller 32 supporting the lower surface of the support member 10C fixed to both end portions of the back surface 10B of the movable deck 10, the elevating means 16 drives the drive shaft 16B to rotate by the operation of the motor 16H, thereby pivoting and raising the elevating member 16C. As a result, the elevating roller 16E provided at the free end of the elevating member 16C supports the elevating guide member 10D fixed facing downward from the back surface 10B of the movable deck 10. At this time, the support roller 32 remains engaged with the positioning surface 10E1 of the positioning member 10E fixed to the movable deck 10.

[0060] Then, as shown in FIG. 13, with the movable deck 10 supported by the elevating roller 16E provided on the elevating member 16C of the elevating means 16, the elevating guide member 10D fixed to the movable deck 10, the support roller 32 disengages from the positioning surface 10E1 of the positioning member 10E fixed to the movable deck 10 and retracts and stops while pivoting from the lower surface of the support member 10C fixed to both end portions of the movable deck 10. As a result, the movable deck 10 can be lowered by the operation of the elevating means 16. Note that the lowering and elevating operations of the movable deck 10 will be described later.

[0061] [Function of the main part] Here, the operation of the main part will be described with reference to FIGS. 14 to 18.

[0062] As shown in FIG. 14, the movable deck 10 is supported by the support rollers 32 of the support means 31. This is the state shown in FIG. 3. In this state, the elevating means 16 is not operating, and the elevating member 16C has descended to the floor side of the pit 24.

[0063] FIG. 15 shows a state where the movable deck 10 is supported by the support rollers 32 of the support means 31 and the elevating member 16C of the elevating means 16. As shown in FIG. 15, while the movable deck 10 is supported by the support rollers 32, the elevating member 16C of the elevating means 16 rotates and the free end rises, and the elevating roller 16E provided at the free end of the elevating member 16C contacts and stops at the elevating guide member 10D fixed to the back surface 10B side of the movable deck 10.

[0064] FIG. 16 shows a state where the movable deck 10 is supported by the elevating member 16C and the support member 32 has retreated to the retracted position from the movable deck 10. As shown in FIG. 16, the movable deck 10 is supported at the position of the vehicle boarding surface in a state of being supported by the elevating roller 16E provided at the free end of the elevating member 16C on the elevating guide member 10D fixed to the back surface 10B side of the movable deck 10. In this state, the support roller 32 retreats while rotating horizontally from the lower surface of the support member 10C of the movable deck 10, and in FIG. 16, the support roller 32 has retreated from the movable deck 10, that is, the support member 10C.

[0065] Figure 17 shows the state where the movable deck 10 has descended from the boarding surface and stopped. As shown in Figure 17, the support roller 32 has retracted from the lifting range of the movable deck 10, and the movable deck 10 is supported by a lifting roller 16E provided at the free end of the lifting member 16C, and descends from the boarding surface by the turning operation of the lifting member 16C. In Figure 17, the movable deck 10 stops while being supported by the lifting member 16C. That is, the movable deck 10 is stopped in the air while being supported by the lifting member 16C of the lifting means 16, which is realized by stopping the rotation of the motor 16H of the lifting means 16 and stopping the rotation of the drive shaft 16B, thereby stopping the turning of the lifting member 16C. Therefore, the movable deck 10 is stopped without requiring any other supporting or placing members other than the lifting member 16C.

[0066] Figure 18 shows the state where the movable deck 10 has been lowered and the support roller 32 has horizontally turned to the support position for supporting the movable deck 10 and stopped. As shown in Figure 18, the movable deck 10 is stopped in the air while being supported by the support member 16C below the boarding surface, but the support roller 32 turns horizontally around the turning shaft 31A and stops at a position where it can support the movable deck 10. This position is the position when the upper tray 8 of the upper and lower two trays 8 is moved between the boarding and alighting chamber 2 and the lifting chamber 4, and the support roller 32 is also used when the tray 8 is moved. This state will be described later.

[0067] The operation when the movable deck 10 descends has been described above. To raise and stop the movable deck 10 on the boarding surface, the reverse operation of the above description is performed.

[0068] Next, with reference to Figures 19 to 21, the support operation of the support roller 32 performed at both longitudinal ends of the movable deck 10 will be supplemented and described.

[0069] Figure 19 shows the state before the movable deck 10 is supported by the support rollers 32. As shown in Figure 19, the surface of the movable deck 10 is located slightly below the boarding surface and is stopped. The movable deck 10 is a place where users, who are drivers of vehicles, walk when getting on and off the vehicle, and may also be used to load and unload luggage onto the vehicle. The movable deck 10 may stop after descending slightly below the boarding surface.

[0070] In such a state, as shown in Figure 20, the support roller 32 is rotatably provided on the pivot shaft 31A and comes into contact while rotating toward the lower surface of the support member 10C of the movable deck 10. Therefore, the support roller 32 enters under the lower surface of the support member 10C while pushing up the movable deck 10.

[0071] Then, as shown in Figure 21, the support roller 32 pushes up the movable deck 10 to the boarding surface and stops its rotation. In this way, since the support roller 32 is configured to support the lower surface of the support member 10C of the movable deck 10 while rotating, even if the movable deck 10 stops in a state slightly lower than the boarding surface, no device or member is required to correct the stop level of the movable deck 10.

[0072] Also, as shown in FIGS. 19 to 21, at the upper part of the turning axis 31A and at a position facing the movable deck 10, a rocking stopper roller 33 that advances and retreats with respect to the rocking stopper surface 10C1, which is the end face of the movable deck 10, is provided. The rocking stopper roller 33 has a function of preventing the rocking of the movable deck 10 in the longitudinal direction, and stops with a slight interval with respect to the rocking stopper surface 10C1 of the movable deck 10. In FIGS. 19 to 21, only one end of the movable deck 10 in the longitudinal direction is shown, but the other end has the same configuration. The reason for setting the rocking stopper roller 33 to stop with a slight interval with respect to the rocking stopper surface 10C1 is that, as described above, when the movable deck 10 is slightly lowered with respect to the boarding surface, even if there is a slight upward movement by the support roller 32, it is considered that an unreasonable force in the vertical direction is not applied to the rocking stopper roller 33. Here, it is also possible not to have an interval between the rocking stopper roller 33 and the rocking stopper surface 10C1. In this case, the rocking stopper roller 33 may be provided so as to move slightly up and down in the vertical direction.

[0073] <Overall operation> Although the support and lifting of the movable deck 10 have been described, here, the operation of the movable deck 10 will be described in addition to the overall operation of the mechanical parking device.

[0074] [Storage operation] The storage operation of the vehicle will be described with reference to FIGS. 22 to 28. In order to avoid complication of the drawings, the illustration of each device related to the conveyance and lifting of the tray 8 and the movable deck 10, and the entrance and exit door 20 is omitted.

[0075] As an initial stage of the storage operation, the arrangement of the tray 8, the movable deck 10, and the lift 42 is shown in FIG. 22. Two trays 8, one above the other, are arranged in the passenger compartment 2. Also, the upper surface 10A of the movable deck 10 is arranged at the same position as the upper surface 8A (boarding surface) of the upper tray 8 (see FIG. 14), the partition door 22 is closed, and in the lift chamber 4, the upper surface of the rail 42A provided on the lift 42 is located at the conveyance level L1 of the upper tray 8.

[0076] As shown in FIG. 23, first, when the user starts the warehousing operation, the presence or absence of the lower tray 8 (hereinafter referred to as the "next tray 8") in the boarding and alighting chamber 2 is determined by the operation of each position detection sensor (not shown). If the next tray 8 exists in the boarding and alighting chamber 2, the next tray 8 will wait as it is.

[0077] Next, the warehoused vehicle M is moved to the lifting chamber 4. As shown in FIG. 23, the partition door 22 is opened in the direction of arrow R1, and at the same time, the movable deck 10 descends in the direction of arrow Q1 (see FIG. 17).

[0078] As shown in FIG. 24, the warehoused vehicle M is placed on the tray 8 and conveyed in the direction of arrow S1 toward the lift 42 waiting in the lifting chamber 4 by the support rollers 32 (see FIGS. 4 and 5). The tray 8 approaching the lift 42 is driven by the drive roller 46 shown in FIG. 5 to the stop position on the lift 42 and stops.

[0079] As shown in FIG. 25, the lift 42 descends in the direction of arrow U1 to store the tray 8 on which the warehoused vehicle M is placed in the storage device 60 (see FIG. 2) of the storage unit 6. In the boarding and alighting chamber 2, the partition door 22 closes in the direction of arrow R2, the movable deck 10 rises in the direction of arrow Q2 (see FIG. 15), and the next tray 8 rises in the direction of arrow T2 and is used for the next warehousing operation. Also, when there is a next user, the next warehousing operation by the next user is performed here.

[0080] As shown in FIG. 26, the descending lift 42 mounts the empty tray 8 on which no vehicle M is placed and rises in the direction of arrow U2, and stops at the level L2 where the next tray 8 below in the boarding and alighting chamber 2 is conveyed. At this time, the movable deck 10 is supported by the support rollers 32 as shown in FIG. 14, and the lifting member 16C of the lifting means 16 descends to the side of the floor of the pit 24.

[0081] Next, as shown in FIG. 27, the empty tray 8 is conveyed from the lift 42 in the direction of arrow S2 and waits as the next tray 8 at the lower tray position in the landing chamber 2. After finishing conveying the empty tray 8, the lift 42 rises in the direction of arrow U3 from level L2 and waits at level L1 (boarding level) where it can receive the tray 8 located on the boarding surface. During this time, in the landing chamber 2, when there is a next warehousing operation, the operation related to the warehousing of the vehicle M is performed simultaneously.

[0082] The above is the operation during the warehousing operation. Thus, in this embodiment, by raising and lowering the movable deck 10 in correspondence with the warehousing operation, the next tray 8 can be prepared even when the warehousing operation is being performed, and even when the lift 42 is descending to the storage section 6, the next tray 8 can be raised in preparation for the next warehousing.

[0083] <Shipping operation> The shipping operation is substantially the same as the reverse operation of the above-described warehousing operation, so it is omitted.

[0084] As described above, the mechanical parking apparatus according to this embodiment includes a tray 8 on which the vehicle M is placed, a landing chamber 2 in which two trays 8 are arranged vertically spaced apart from each other, a lift chamber 4 adjacent to the landing chamber 2 and in which a lift 42 on which one tray 8 is mounted and moves up and down is arranged, and a movable deck 10 arranged between the tray 8 and the lift chamber 4 so as to be movable up and down by a lifting means 16. The lift 42 is allowed to change its stop position corresponding to the conveyance height L1 of the tray 8 located above among the trays 8 arranged in the landing chamber 2 and the conveyance height L2 of the tray 8 located below among the trays 8 arranged in the landing chamber 2 during the warehousing and shipping operations. When the lift 42 is located at the lower conveyance height L2, the tray 8 located below is allowed to be conveyed between the landing chamber 2 and the lift 42 during the warehousing and shipping operations. The movable deck 10 is moved to a position that allows the movement of the tray 8 located above when the tray 8 located above moves between the landing chamber 2 and the lift chamber 4, and is moved to a position that allows the movement of the tray 8 located below when the tray 8 located below moves between the landing chamber 2 and the lift chamber 4.

[0085] As a result, compared with the case where the movable deck 10 is fixed inside the boarding and alighting compartment 2, it becomes possible to replace the trays during the loading and unloading operations, and it is possible to suppress the extension of the loading and unloading time of the vehicle.

[0086] In addition, the position that allows the movement of the tray 8 located above the movable deck 10 is set to a position below the tray 8 located above, and the position that allows the movement of the tray 8 located below the movable deck 10 is set to a position above the tray 8 located below.

[0087] As a result, compared with the case where the movable deck 10 is folded or raised to near the ceiling during the loading and unloading operations, it is possible to suppress the extension of the loading and unloading time of the vehicle.

[0088] Further, the lifting means 16 includes a motor 16H, a drive shaft 16B operatively connected to the motor 16H, and a lifting member 16C having one end fixed to the drive shaft 16B and the other end being a rotatable free end. When the drive shaft 16B is driven by the motor 16H, the free end of the lifting member 16C rotates while supporting the back surface 10B of the movable deck 10, thereby raising and lowering the movable deck 10.

[0089] As a result, compared with the case where the movable deck 10 is of the rack and pinion type or the rope lifting type, a simple structure can achieve cost reduction and improvement of maintenance efficiency.

[0090] In addition, a pair of lifting members 16C are provided at intervals in the direction of one side of the movable deck 10, and the pair of lifting members 16C are fixed to both ends of the drive shaft 16B.

[0091] As a result, compared with the case where there is one lifting member 16C, the lifting operation of the movable deck 10 is stabilized.

[0092] In addition, the free end of the lifting member 16C has a lifting roller 16E that rotatably contacts the back surface 10B of the movable deck 10.

[0093] As a result, compared with the case where the free end of the elevating member 16C slides on the back surface of the movable deck 10, noise and vibration can be suppressed, and maintenance efficiency can be improved.

[0094] In addition, a pair of elevating means 16 are provided at intervals in the direction of the other side of the movable deck 10, and the pair of elevating means 16 operate synchronously.

[0095] As a result, compared with the case where there is only one elevating means 16, the elevating operation of the movable deck 10 is stabilized with a small driving force.

[0096] In addition, the elevating means 16 are arranged such that the free ends of the elevating members 16C face each other.

[0097] As a result, compared with the case where the two elevating means 16 are arranged to face different directions, the elevating operation of the movable deck 10 is stabilized.

[0098] In addition, when the movable deck 10 is moved to a position that allows the movement of the tray 8 located below, it is supported by the support means 31.

[0099] As a result, compared with the case where the movable deck 10 is supported only by the elevating member 16C, the movable deck 10 is reliably supported, and the sway and displacement of the movable deck 10 during the user's walking are suppressed.

[0100] In addition, when the movable deck 10 is moved to a position that allows the movement of the tray 8 located above, it is stopped while being supported by the elevating member 16C.

[0101] As a result, compared with the case of using a member on which the movable deck 10 is placed when the movable deck 10 descends and stops, the movable deck 10 can be stopped at a predetermined position only by stopping the elevating member 16C in the middle.

[0102] <Modification example> Here, a modified example of the elevating means will be described with reference to FIGS. 29 and 30. The same reference numerals will be used for the same configurations as in the above-described embodiment.

[0103] As shown in FIGS. 29 and 30, in the modified example, the elevating means 160 differs from that in the above-described embodiment in the configuration of the motor 161H and the drive shaft 161B. The motor 161H of the elevating means 160 is arranged in a direction orthogonal to the drive shaft 161B, and has shafts extending from both sides in the device width direction W, that is, in the direction of the drive shaft 161B, from the reduction gear portion of the motor 161H. The drive shafts 161B, 161B that are split left and right are respectively connected to the coupling 162, 162. As a result, bearings 161A, 161A are added to support the drive shaft 161B. Thus, in this modified example, since a configuration without using gears is adopted, the maintenance efficiency can be improved.

[0104] The embodiments of the present invention have been described with one embodiment, but this embodiment is merely an example, and various modifications can be made without departing from the gist of the present invention. Needless to say, the scope of rights of the present invention is not limited to these embodiments.
