Description

[Technical Field]

[0001] The present invention relates to a tire stopper for a pallet, a pallet for a mechanical parking device, and a mechanical parking device. [Background technology]

[0002] Mechanical parking systems are used to park multiple vehicles in a limited space. Mechanical parking systems are installed underground in apartment buildings, office buildings, shopping centers, etc., or above ground adjacent to the buildings.

[0003] An underground parking system is an example of a mechanical parking system. A horizontal circulation type parking system (hereinafter referred to as a "horizontal circulation type parking system") is an example of an underground parking system.

[0004] The horizontal circulation parking system comprises a loading / unloading section, pallets, a lift, and multiple storage sections. The loading / unloading section is a space where vehicles are loaded and unloaded. Vehicles that have been loaded forward from the loading / unloading section are placed (loaded) on the pallets. The pallets are transported up and down the elevator shaft by the lift rising and falling, and are also transported horizontally through the underground storage space. The elevator shaft is a vertical transport path for the pallets that connects the loading / unloading section and the storage floor where the storage sections are located. The shape of the pallet in a plan view is rectangular. The pallet is transported in the longitudinal direction of the pallet (the front-to-rear direction of the vehicle placed on the pallet) and the lateral direction of the pallet (the width direction of the vehicle placed on the pallet). The operation of transporting the pallet in the longitudinal direction is called "vertical feeding," and the operation of transporting the pallet in the lateral direction is called "horizontal feeding." The lift raises and lowers pallets with vehicles placed on them or pallets without vehicles placed on them (hereinafter referred to as "empty pallets") in the hoistway. The storage section is an area on the storage floor where pallets (including empty pallets) are stored. The storage section is divided into multiple storage spaces.

[0005] When a pallet carrying a vehicle is transported vertically, the vehicle may move from its resting position on the pallet due to acceleration caused by the vertical transport or inertia caused by the pallet stopping during transport (movement). In other words, when a pallet carrying a vehicle is transported vertically, the position of the vehicle's tires may be displaced. Such displacement of tire position is particularly likely to occur when the parking brake of the vehicle placed on the pallet is forgotten to be applied. If the tire position is displaced during vertical transport, the vehicle may fall off the pallet. To solve this problem, a pallet has been proposed in which tire chocks (wheel stop devices) that restrict the movement of the vehicle's tires are arranged on the top surface of the pallet (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-129374

[0007] The tire stopper (car stop device) disclosed in Patent Document 1 includes multiple rod-shaped members (car stoppers) fixed to the top surface of a pallet. The multiple rod-shaped members are arranged at predetermined intervals on one side of the shorter side (for example, on the right front tire side of the vehicle) at the front end side of the longitudinal direction of the pallet (the front side in the approach direction when a vehicle advances onto the pallet). The spaces between each rod-shaped member on the top surface of the pallet form stopping positions for the tires. The stopping positions are positions where the tires (right front tire) of a vehicle placed on the pallet are placed. The rod-shaped members arranged before and after the stopping positions restrict displacement of the tires in the fore-and-aft direction when a vehicle is placed on the pallet (when a tire is placed at a stopping position).

[0008] The tire stopper disclosed in Patent Document 1 has rod-shaped members positioned in front and behind the tire when the vehicle is placed on the pallet. The tire stopper disclosed in Patent Document 1 can restrict the tire's longitudinal displacement with the rod-shaped members even if acceleration or inertia occurs during vertical transport of the pallet. As a result, the vehicle is prevented from falling off the pallet. Summary of the Invention [Problem to be solved by the invention]

[0013] Hereinafter, an embodiment (hereinafter referred to as "first embodiment") of a tire stopper for a pallet, a pallet for a mechanical parking device, and a mechanical parking device according to the present invention will be described with reference to the drawings.

[0014] The embodiment described below is an example in which the mechanical parking system according to the present invention (hereinafter referred to as "the system") is a horizontal circulation type parking system that allows forward parking.

[0015] In the following description, the direction in which the vehicle approaches the pallet is referred to as the "forward" direction in this specification, and the opposite direction to the approaching direction is referred to as the "rear" direction in this specification. The left side of the approaching direction is referred to as the "left" direction in this specification, and the right side of the approaching direction is referred to as the "right" direction in this specification.

[0016] ●Mechanical parking device● ●Configuration of mechanical parking device FIG. 1 is a cross-sectional view showing an embodiment of the present device. The figure shows a schematic diagram of a state in which a plurality of vehicles are stored (parked) in an underground storage space. The storage space is provided on multiple floors (2 floors).

[0017] The device 1 includes a storage space SP, an elevator shaft UD, a pallet 10, an entry / exit section 20, an entry / exit gate 30, a lift 40, and a transport device 50. The device 1 transports the pallet 10 in the forward / backward and left / right directions in the underground storage space SP to store multiple vehicles C.

[0018] The storage space SP stores multiple vehicles C. The storage space SP has multiple storage floors (first storage floor B1, second storage floor B2). The first storage floor B1 is located above the second storage floor B2 (on the ground level: the upper side of the paper in FIG. 1). The second storage floor B2 is located below the first storage floor B1. That is, for example, the first storage floor B1 is the first basement floor. The second storage floor B2 is the second basement floor.

[0019] 2, the first storage floor B1 includes a plurality of storage sections B11, B12, ... B1n (n = integer). Each of the plurality of storage sections stores a pallet 10 (10a, 10b, ..., 10i, 10z) and a vehicle C placed on the pallet 10.

[0020] The second storage floor B2, like the first storage floor, is equipped with a plurality of storage sections.

[0021] In the present invention, the number of storage floors arranged in the storage space is not limited to "2." That is, for example, the number of storage floors may be "1," or may be "3" or more.

[0022] The elevator shaft UD is a passageway that connects the loading / unloading section 20 and the storage space SP. A lift 40 moves up and down in the elevator shaft UD.

[0023] FIG. 2 is a schematic plan view showing the storage space SP. The figure shows a schematic plan view of the first storage floor B1 in the storage space SP. However, for ease of explanation, the vehicle C is omitted from the illustration. The figure shows that the first storage floor B1 includes 11 storage sections B1-B111. The figure shows that pallets 10 are placed in 9 of the 11 storage sections B1-B111. In other words, the first storage floor B1 shows that two empty spaces are placed. In other words, the device 1 can store 9 vehicles C on the first storage floor B1. The configuration of the storage sections placed on the second storage floor B2 is the same as the configuration of the storage sections placed on the first storage floor B1.

[0024] In the present invention, the number of storage sections arranged on each storage floor and the number of vehicles that can be stored in each storage section are not limited to the above-mentioned numbers.

[0025] The following description of the configuration of the device 1 will also refer to Figure 1. In the following description, the planar (horizontal) transportation of pallets 10 will be described using the case where they are transported on the first storage floor B1 as an example. In the following description, when describing individual pallets specifically, they will be described with individual reference numerals (10a-10i, 10z), and when describing pallets collectively, they will be described simply as pallet 10.

[0026] The pallets 10 (10a-10i, 10z) are used to place the vehicle C. The pallets 10 are placed on the lift 40 and one of the storage sections B11-B111 via the transport device 50. The pallets 10 are transported between the loading / unloading section 20 and the storage space SP, and move horizontally on the first storage floor B1. The shape of the pallets is rectangular in plan view. The pallets 10 are an example of a pallet for a mechanical parking device in the present invention. The specific configuration of the pallets 10 will be described later.

[0027] The loading / unloading section 20 is a space where the vehicle C enters and leaves the garage. The loading / unloading section 20 is located, for example, on the ground floor. When entering the garage, the vehicle C enters the loading / unloading section 20. When leaving the garage, the vehicle C leaves the garage forward from the loading / unloading section 20. The loading / unloading section 20 includes a platform 21, an opening 22h, and a turntable (not shown).

[0028] The platform 21 forms the floor of the loading / unloading area 20.

[0029] The opening 22h is a hole that connects the loading / unloading section 20 (the space excluding the opening 22h) with the elevator shaft UD. The pallet 10 is transported between the loading / unloading section 20 and the elevator shaft UD through the opening 22h. The opening 22h is placed on the platform 21. The opening area of the opening 22h is slightly larger than the planar area of the pallet 10. When the vehicle C is ready to load / unload the loading / unloading section 20, the pallet 10 is placed in the opening 22h. When the pallet 10 is placed in the opening 22h, the upper surface (surface) of the platform 21 forms a substantially flat surface with the upper surface (surface) of the pallet 10.

[0030] The turntable rotates the pallet 10 .

[0031] The entrance / exit section is not limited to a configuration that allows a vehicle to enter or exit the parking lot in a forward direction. For example, the entrance / exit section may be a configuration that allows a vehicle to enter or exit the parking lot in a backward direction. Furthermore, the entrance / exit section does not have to be equipped with a turntable.

[0032] The entrance / exit 30 is an entrance / exit for the vehicle C to / from the entrance / exit section 20. The entrance / exit 30 is provided with an openable / closable door 31.

[0033] The door 31 prevents the movement of the vehicle C between the inside and outside of the loading / unloading section 20. The door 31 opens and closes when an operation panel (not shown) is operated by a user of the device 1, an administrator of the device 1, or the like. That is, for example, when the door 31 is "open," the vehicle C can move between the inside and outside of the loading / unloading section 20. When the door 31 is "closed," the vehicle C cannot move between the inside and outside of the loading / unloading section 20. The door 31 is located behind the vehicle C that has advanced into the loading / unloading section 20.

[0034] The "user" is, for example, the driver or passenger of the vehicle C. The "manager" is, for example, a person who guides the user of the device 1 in entering and leaving the facility, or a manager or maintenance person of the device 1.

[0035] The lift 40 raises and lowers the pallet 10 in the elevator shaft UD, moving the pallet 10 between the loading / unloading section 20, the first storage floor B1, and the second storage floor B2. The lift 40 places the pallet 10 via the conveying device 50. The pallet 10 placed on the lift 40 is either a pallet on which a vehicle C is placed, or an empty pallet.

[0036] The conveying device 50 conveys the pallets 10 horizontally (front-back and left-right) on the first storage floor B1. The conveying device 50 is equipped with drive rollers 51. The drive rollers 51 are rotated by the power of a drive device (not shown). The drive rollers 51 support the underside of the pallet 10 (vertical rails 12a and horizontal rails 12b described below). The conveying device 50 is equipped with a first conveying device 50a mounted on the lift 40 and a second conveying device 50b mounted on each of the storage sections B11-B111. The configuration of the first conveying device 50a is the same as the configuration of the second conveying device 50b. That is, the first conveying device 50a is equipped with drive rollers 51a, and the second conveying device 50b is equipped with drive rollers 51b.

[0037] The first conveying device 50a conveys the pallet 10 placed on the lift 40 to the second conveying device 50b by rotation of the drive roller 51a. The second conveying device 50b conveys the pallet 10 placed on the second conveying device 50b to another second conveying device 50b or the first conveying device 50a by rotation of the drive roller 51b.

[0038] The pallet 10 is transported in the front-to-back direction (longitudinal direction) and left-to-right direction (transverse direction) on the first storage floor B1 by the rotation of the drive rollers 51a, 51b. The operation of transporting the pallet 10 in the front-to-back direction is called "vertical feeding," and the operation of transporting the pallet 10 in the left-to-right direction is called "horizontal feeding."

[0039] ● Operation of mechanical parking devices Next, the operation of the device 1 will be described.

[0040] ● Warehousing operation First, after vehicle C is parked in front of door 31 of loading / unloading entrance 30, when a user or manager operates the operation panel, an empty pallet (pallet 10z) is transported to loading / unloading section 20 and placed in opening 22h. When pallet 10z is placed in opening 22h of loading / unloading section 20, door 31 opens.

[0041] Next, vehicle C enters loading / unloading section 20 through loading / unloading entrance 30, and when vehicle C stops at a predetermined location (stopping position) on pallet 10z (tire T of vehicle C is placed at a predetermined position), door 31 closes by operation of the operation panel by a user or manager. After stopping vehicle C at a predetermined location on pallet 10z, the user gets off vehicle C and exits the device 1. The direction in which vehicle C enters loading / unloading section 20 (pallet 10z) (hereinafter referred to as "entry direction") is along the longitudinal direction of pallet 10z.

[0042] The "predetermined location on the pallet 10" is a location where any of the ends of the front, rear, left, and right sides of the vehicle C fits within the space on the top surface of the pallet 10.

[0043] The "stop position" is the position on the top surface of the pallet 10 where a tire stopper 14 (see FIG. 3), which will be described later, is arranged.

[0044] The "approaching direction" refers to a direction intersecting the short side direction of the pallet 10 (not limited to a direction perpendicular to the short side direction), and is broadly interpreted to mean any direction intersecting the short side direction of the pallet 10. In other words, a direction perpendicular to the short side direction of the pallet 10, as well as any direction other than a direction perpendicular to the short side direction of the pallet 10, are all "approaching directions." In other words, even when "vehicle C approaches pallet 10 at a slight angle," the approaching direction is a direction along the longitudinal direction of the pallet 10.

[0045] When the vehicle is not in the designated location on the pallet (when at least one of the front, rear, left, or right ends of the vehicle protrudes from the space on the top surface of the pallet), the door will not close even when the control panel is operated.When the mechanical parking device detects that the vehicle is not in the designated location on the pallet, it notifies the driver that the vehicle is not in the designated location on the pallet by audio guidance from a speaker (not shown) or by displaying on a display panel.

[0046] The "notice that the vehicle is not in the designated place on the pallet" is, for example, a notice to re-enter the pallet or a notice informing the user that the vehicle being stored is out of specification and cannot be stored. The fact that the vehicle is not in the designated place on the pallet is detected, for example, by a sensor (not shown) that detects vehicles protruding from the pallet and is arranged in the storage / retrieval section.

[0047] Next, after the door 31 closes, the pallet 10z on which the vehicle C is placed descends down the elevator shaft UD as the lift 40 descends. The pallet 10z stops at the first storage floor B1 under the control of a control unit (not shown). The pallet 10z that has stopped at the first storage floor B1 is fed vertically or horizontally by the rotation of the drive roller 51a and is transported to the adjacent second transport device 50b.

[0048] The second conveying device 50b conveys the pallet 10z vertically or horizontally to another adjacent second conveying device 50b by rotating the drive roller 51b. In this way, the device 1 stores the pallet 10 in a desired storage section (an empty space where no other pallets 10a-10i are placed). When the second conveying device 50b conveys the pallet 10z to a desired storage section, the other pallets 10a-10i placed on the second conveying device 50b are conveyed vertically or horizontally as appropriate. In other words, the device 1 stores the pallet 10z in a desired storage section by moving the pallet 10z and the other pallets 10a-10i placed on the second conveying device 50b like a puzzle.

[0049] ●Removal operation The following description will be given of the retrieval operation by the device 1, taking as an example the case where a vehicle C placed on a pallet 10z stored in the storage section B16 is retrieved (the pallet 10z is not shown in FIG. 2). The retrieval operation is substantially the opposite of the retrieval operation. Therefore, a description of the retrieval operation that is common to the retrieval operation will be omitted.

[0050] First, when a user or manager of the vehicle C placed on the pallet 10z operates an operation panel (not shown), the device 1 calls the pallet 10z.

[0051] The pallet 10z is transported vertically or horizontally by the rotation of the drive roller 51b of the second transport device 50b placed in the storage section B16, and is transported to the first transport device 50a placed on the lift 40 in the elevator shaft UD. When the pallet 10z is transported from the second transport device 50b placed in the storage section B16 to the first transport device 50a, the pallets 10a-10i placed on each of the second transport devices 50b are transported vertically or horizontally as appropriate.

[0052] After the pallet 10z is placed on the first conveying device 50a, the pallet 10z rises up the elevator shaft UD as the lift 40 rises. The pallet 10z stops at the opening 22h of the loading / unloading section 20 under the control of the control unit. When the pallet 10z stops at the opening 22h of the loading / unloading section 20, the vehicle C placed on the pallet 10z is positioned with the rear side of the vehicle C facing the door 31. The pallet 10z is rotated 180 degrees by the rotation of a turntable (not shown), and the front side of the vehicle C is positioned facing the door 31.

[0053] Next, the door 31 opens, and the user gets into the vehicle C and drives it forward out of the loading / unloading section 20 (the device 1). After the vehicle C has left the parking lot, the door 31 closes by the user or the caretaker operating the control panel.

[0054] ●Pallets for mechanical parking devices (1) FIG. 3 is a top perspective view of the pallet 10.

[0055] The pallet 10 includes a pallet body 11, vertical rails 12a, horizontal rails 12b, a turning portion 13, and a tire stopper 14.

[0056] A vehicle C (see FIG. 1) is placed on the pallet body 11. The pallet body 11 is, for example, a plate-like member made of steel. The pallet body 11 has a rectangular shape.

[0057] The vertical rails 12a are arranged on the underside (backside) of the pallet body 11 and extend in the longitudinal direction of the pallet body 11 (from upper left to lower right on the paper in FIG. 3). The vertical rails 12a are supported by drive rollers 51 when the pallet 10 is fed vertically. The vertical rails 12a are, for example, H-shaped steel, made of the same steel material as the pallet body 11. Two vertical rails 12a are arranged with a gap between them in the short side direction of the pallet body 11 (from lower left to upper right on the paper in FIG. 3). In FIG. 3, the dashed line extending in the longitudinal direction indicates the position of the vertical rails 12a arranged on the underside of the pallet body 11. The vertical rails 12a are discontinuous at predetermined locations in the longitudinal direction.

[0058] The horizontal rail 12b is disposed on the underside (backside) of the pallet body 11 and extends in the short-side direction (from the lower left to the upper right on the paper in FIG. 3). The horizontal rail 12b is supported by the drive roller 51 when the pallet 10 is fed laterally. The horizontal rail 12b is, for example, an H-shaped steel, and is made of the same steel material as the pallet body 11. Two horizontal rails 12b are disposed at a distance in the longitudinal direction. In FIG. 3, the dashed line extending in the short-side direction indicates the position of the horizontal rail 12b disposed on the underside of the pallet body 11. The horizontal rail 12b is discontinuous at a predetermined location in the short-side direction. The discontinuous location of the horizontal rail 12b is the intersection with the discontinuous location of the vertical rail 12a. A turning portion 13 is disposed between the discontinuous location of the vertical rail 12a and the discontinuous location of the horizontal rail 12b.

[0059] The turning units 13 change the conveying direction of the pallets 10 to switch between vertical feeding and horizontal feeding. The turning units 13 are arranged at intersections. The number of turning units 13 is, for example, "4." The turning units 13 are equipped with turning rails (not shown).

[0060] The diverting rail is disposed on the underside of the pallet body 11 at the diverting section 13. The diverting rail rotates between the longitudinal direction and the lateral direction of the pallet body 11, with a rotation axis perpendicular to the planar direction of the pallet body 11. That is, the diverting rail can be switched between facing the longitudinal direction and facing the lateral direction. That is, when the diverting rail faces the longitudinal direction, it is located on an extension of the vertical rail 12a, and when facing the lateral direction, it is located on an extension of the horizontal rail 12b. In other words, when the diverting rail faces the longitudinal direction, the pallet 10 is fed longitudinally, and when the diverting rail faces the lateral direction, the pallet 10 is fed transversely.

[0061] The tire stopper 14 restricts the displacement of the vehicle C placed on the pallet 10, that is, restricts the movement of the vehicle C on the pallet 10.

[0062] Pallet tire stopper (1) FIG. 4 is an enlarged view of the tire stopper 14. FIG. 5 is a side view showing an embodiment of a tire stopper for a pallet according to the present invention. FIG. 6 shows an example of how the tire stopper 14 is used.

[0063] The tire stopper 14 is disposed on the upper surface of the pallet body 11 (pallet 10) and on the right side of the front side of the pallet body 11. That is, for example, the tire stopper 14 is disposed on the right front tire side of the vehicle C. The tire stopper 14 includes a first rod-shaped member 141, a second rod-shaped member 142, and a plate-shaped member 151. The tire stopper 14 is an example of a tire stopper for a pallet in the present invention.

[0064] The first rod-shaped member 141 restricts forward (forward in the approach direction) displacement of the tire T when the vehicle C is stopped at a predetermined position on the pallet 10 (when the right front tire T (see FIG. 6) of the vehicle C is placed at a predetermined position). The first rod-shaped member 141 also functions as an indicator of the stopping position of the vehicle C when the vehicle C is approaching the pallet 10.

[0065] The first rod-shaped member 141 has a cylindrical shape and is arranged along the short side direction (the direction perpendicular to the approach direction). The first rod-shaped member 141 is made of the same steel material as the pallet body 11.

[0066] The second rod-shaped member 142 restricts rearward (rearward in the approach direction) displacement of the tire T when the vehicle C is stopped at a predetermined location on the pallet 10 (when the right front tire T of the vehicle C is placed at a predetermined position). The second rod-shaped member 142 also functions as an indicator of the stopping position of the vehicle C when the vehicle C is allowed to approach the pallet 10. The space between the first rod-shaped member 141 and the second rod-shaped member 142 functions as the stopping position of the tire T.

[0067] The second rod-shaped member 142 has a cylindrical shape and is arranged along the short side direction. The second rod-shaped member 142 is made of the same steel material as the pallet body 11. The second rod-shaped member 142 is arranged at a predetermined distance from the first rod-shaped member 141. The second rod-shaped member 142 is arranged parallel to the first rod-shaped member 141.

[0068] The diameter of the first rod-shaped member 141 is the same as the diameter of the second rod-shaped member 142. The first rod-shaped member 141 is disposed further forward (farther back) than the second rod-shaped member 142 in the insertion direction.

[0069] The plate-like member 151 is disposed on and joined to the first rod-like member 141 and the upper surface of the pallet body 11 (pallet 10) between the first rod-like member 141 and the second rod-like member 142. The plate-like member 151 is an inclined plate that slopes from the first rod-like member 141 to the upper surface of the pallet body 11 (pallet 10). That is, the inclination of the plate-like member 151 is an upward inclination with respect to the entry direction. The inclination of the plate-like member 151 is, for example, approximately 6 degrees. The shape of the plate-like member 151 is rectangular. The plate-like member 151 has a first joining side S1 and a second joining side S2 that are disposed opposite each other.

[0070] In this embodiment, the tire T of the vehicle C placed on the pallet 10 is disposed between the first rod-shaped member 141 and the second rod-shaped member 142. The tire T is placed on the plate-shaped member 151. In other words, the tire T abuts against the plate-shaped member 151. More preferably, when the tire T is disposed between the first rod-shaped member 141 and the second rod-shaped member 142, the tire T abuts against the plate-shaped member 151 and also against the second rod-shaped member 142.

[0071] The first joining side S1 of the plate-shaped member 151 is joined to the upper part of the first rod-shaped member 141. The first joining side S1 is joined to the first rod-shaped member 141 by, for example, welding or bolts. The first joining side S1 is an example of the first side in the present invention.

[0072] The second joining edge S2 of the plate-like member 151 is joined to the upper surface of the pallet body 11. The second joining edge S2 is joined to the upper surface of the pallet body 11 by, for example, welding or bolting. The second joining edge S2 is an example of the second edge in the present invention.

[0073] The second joining edge S2 of the plate-shaped member 151 is joined to the upper surface of the pallet body 11 in the vicinity of the second rod-shaped member 142, between the first rod-shaped member 141 and the second rod-shaped member 142. "In the vicinity of the second rod-shaped member 142" is a position closer to the second rod-shaped member 142 than the midpoint between the first rod-shaped member 141 and the second rod-shaped member 142.

[0074] ●Summary (1)● According to the embodiment described above, the pallet 10 included in the device 1 includes the tire stopper 14. The tire stopper 14 includes a first rod-shaped member 141, a second rod-shaped member 142, and a plate-shaped member 151. A first joint edge S1 of the plate-shaped member 151 is joined to an upper portion of the first rod-shaped member 141, and a second joint edge S2 of the plate-shaped member 151 is joined to the upper surface of the pallet body 11 between the first rod-shaped member 141 and the second rod-shaped member 142. When the vehicle C is placed on the pallet 10, the right front tire T of the vehicle C is placed in the stopping position. In this case, the tire T is placed on the plate-shaped member 151. The inclined plate-shaped member 151 and the second rod-shaped member 142 restrict displacement of the tire T in the front-rear direction. This allows the tire stopper 14 to prevent the vehicle C from falling off the pallet 10.

[0075] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10, the inclined plate-like member 151 can restrict the tire T of the vehicle C placed on the pallet 10 from displacing forward more effectively than conventional tire stops.

[0076] Furthermore, as described above, when the vehicle C is placed on the pallet 10, the right front tire T of the vehicle C is placed on the plate-shaped member 151. In this case, the tire T may also come into contact with the second rod-shaped member 142. That is, the tire T comes into contact with the plate-shaped member 151 and the second rod-shaped member 142 at two points. This increases the effect of restricting the displacement of the tire T in the front-rear direction.

[0077] The position where the tire stopper is placed is not limited to the right side of the front side of the pallet body. That is, for example, the tire stopper may be placed on the left side of the front side of the pallet body or on both the left and right sides of the front side.

[0078] The tire stoppers may also be arranged on both the left and right sides of the rear side of the pallet body, or on either the left or right side of the rear side.

[0079] Furthermore, the tire stops may be arranged on both the front and rear of the pallet body, on either the left or right side, or on both the left and right sides.

[0080] Furthermore, each of the first rod-shaped member and the second rod-shaped member may have a triangular prism or a square prism shape instead of a cylindrical shape.

[0081] Furthermore, the second joining edge may be disposed not only on the upper surface of the pallet body but also on the second rod-shaped member. In this case, the second joining edge is joined to the second rod-shaped member and the upper surface of the pallet body.

[0082] Furthermore, both the first rod-shaped member 141 and the second rod-shaped member 142 are directly disposed on and joined to the upper surface of the pallet body 11. However, the first rod-shaped member and the second rod-shaped member may each be disposed on the pallet body via one or more support members disposed on the upper surface of the pallet body. That is, one or more support members corresponding to the first rod-shaped member and the second rod-shaped member are disposed on the upper surface of the pallet body, and the first rod-shaped member and the second rod-shaped member are disposed on the upper surfaces of the one or more support members. In this case, the first rod-shaped member is bonded to the upper surface of the pallet body together with the support members, and the second rod-shaped member is disposed on the upper surface of the pallet body together with the support members.

[0083] Furthermore, the plate-like member may be joined to the pallet body via a reinforcing member between the lower surface (the surface facing the pallet body) of the plate-like member and the upper surface of the pallet body. In this case, the upper surface of the pallet body is joined to the reinforcing member, and the lower surface of the plate-like member is joined to the reinforcing member.

[0084] ●Modification of pallet tire stopper (1)● A modified example of the tire stopper for a pallet according to the present invention will now be described.

[0085] Pallet tire stopper (1) variant (1) The tire stopper for a pallet according to the present invention may be configured so that the first joining edge of the plate-shaped member is positioned on the upper surface of the pallet body, and the second joining edge of the plate-shaped member is positioned on the upper surface of the second rod-shaped member and joined together.

[0086] FIG. 7 is a schematic side view showing a modified example of the tire stopper. The tire stopper 14a is disposed on the upper surface of the pallet main body 11a (pallet 10a). The tire stopper 14a includes a first rod-shaped member 141a, a second rod-shaped member 142a, and a plate-shaped member 151a.

[0087] This figure shows that the inclination of the plate-like member 151a is downward with respect to the approach direction.

[0088] The plate-like member 151a is disposed on and joined to the second rod-like member 142a and the upper surface of the pallet main body 11a (pallet 10a) between the first rod-like member 141a and the second rod-like member 142a. The plate-like member 151a is an inclined plate that slopes from the second rod-like member 142a to the upper surface of the pallet main body 11a. That is, the inclination of the plate-like member 151a is downward with respect to the entry direction.

[0089] The first joining side S1a of the plate-shaped member 151a is joined to the upper surface of the pallet body 11a, and the second joining side S2a of the plate-shaped member 151a is joined to the upper part of the second rod-shaped member 142a.

[0090] In tire stopper 14a, when a vehicle (not shown) is placed on pallet 10a, the tire (not shown) of the vehicle is placed in a stopping position and also placed on plate-shaped member 151a. Displacement of the tire in the front-rear direction is restricted by inclined plate-shaped member 151a and first rod-shaped member 141a. In this way, tire stopper 14a can prevent the vehicle from falling off pallet 10a.

[0091] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10a, the inclined plate-like member 151a can restrict rearward displacement of the tires of the vehicle placed on the pallet 10a more effectively than conventional tire stops.

[0092] Pallet tire stopper (1) modified version (2) In the present invention, the diameter of the first rod-shaped member may be different from the diameter of the second rod-shaped member.

[0093] FIG. 8 is a schematic side view showing another modified example of the tire stopper. The tire stopper 14b is disposed on the upper surface of the pallet main body 11b (pallet 10b). The tire stopper 14b includes a first rod-shaped member 141b, a second rod-shaped member 142b, and a plate-shaped member 151b.

[0094] This figure shows that the diameter of the first rod-shaped member is larger than the diameter of the second rod-shaped member.

[0095] The diameter of the first rod-shaped member 141b is larger than the diameter of the second rod-shaped member 142b. The first rod-shaped member 141b is disposed further forward than the second rod-shaped member 142b in the insertion direction.

[0096] The plate-like member 151b is disposed on and joined to the first rod-like member 141b and the upper surface of the pallet main body 11b (pallet 10b) between the first rod-like member 141b and the second rod-like member 142a. The plate-like member 151b is an inclined plate that slopes from the first rod-like member 141b to the upper surface of the pallet main body 11b. In other words, the inclination of the plate-like member 151b is an upward slope relative to the entry direction.

[0097] The first joining side S1b of the plate-shaped member 151b is joined to the upper part of the first rod-shaped member 141b. The second joining side S2b of the plate-shaped member 151b is joined to the upper surface of the pallet main body 11b. Therefore, the inclination of the plate-shaped member 151b is greater than the inclination of the plate-shaped member 151 in the first embodiment (see FIG. 5).

[0098] In tire stopper 14b, when a vehicle (not shown) is placed on pallet 10b, the tire (not shown) of the vehicle is placed in a stopping position and also placed on plate-like member 151b. Displacement of the tire in the front-rear direction is restricted by inclined plate-like member 151b and second rod-like member 142b. This allows tire stopper 14b to prevent the vehicle from falling off pallet 10b.

[0099] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10b, the inclined plate-like member 151b can restrict the forward displacement of the tires of the vehicle placed on the pallet 10b more effectively than conventional tire stops.

[0100] Pallet tire stopper (1) modified version (3) 8, the tire chock for the pallet according to the present invention may have a configuration in which the diameter of the first rod-shaped member 141b is larger than the diameter of the second rod-shaped member 142b. However, the tire chock for the pallet according to the present invention may have a configuration in which the diameter of the first rod-shaped member is smaller than the diameter of the second rod-shaped member.

[0101] Pallet tire stopper (1) modified version (4) 8, the tire stopper for a pallet according to the present invention may have a configuration in which the first joining edge S1b of the plate-shaped member 151b is joined to the top of the first rod-shaped member 141b, and the second joining edge S2b of the plate-shaped member 151b is joined to the top surface of the pallet main body 11b. However, the tire stopper for a pallet according to the present invention may have a configuration in which the first joining edge of the plate-shaped member is joined to the top surface of the pallet main body, and the second joining edge of the plate-shaped member is joined to the top of the second rod-shaped member.

[0102] Pallet tire stopper (1) modified version (5) 8, the tire chock for the pallet according to the present invention may have a configuration in which the diameter of the first rod-shaped member 141b is larger than the diameter of the second rod-shaped member 142b, the first joining edge S1b of the plate-shaped member 151b is joined to the top of the first rod-shaped member 141b, and the second joining edge S2b of the plate-shaped member 151b is joined to the top surface of the pallet body 11b. However, the tire chock for the pallet according to the present invention may have a configuration in which the diameter of the first rod-shaped member is smaller than the diameter of the second rod-shaped member, the first joining edge of the plate-shaped member is joined to the top surface of the pallet body, and the second joining edge of the plate-shaped member is joined to the top of the second rod-shaped member.

[0103] ●Pallets for mechanical parking devices (2) Next, another embodiment of the pallet for a mechanical parking device according to the present invention (hereinafter referred to as the "second embodiment") will be described, focusing on the differences from the first embodiment. The second embodiment differs from the first embodiment in the number of rod-shaped members and the number of plate-shaped members that make up the tire stopper.

[0104] FIG. 9 is a top perspective view showing another embodiment of a pallet for a mechanical parking system according to the present invention.

[0105] The pallet 10A of the mechanical parking device provided in this device (not shown) includes a pallet body 11A, vertical rails 12a, horizontal rails 12b, a turning section 13, and a tire stopper 14A. The tire stopper 14A restricts the displacement (movement) of a vehicle C (see FIG. 12) placed on the pallet 10A.

[0106] Pallet tire stoppers (2) FIG. 10 is an enlarged view of the tire stopper 14A. FIG. 11 is a schematic side view showing another embodiment of a tire stopper for a pallet according to the present invention. FIG. 12 shows an example of how the tire stopper 14A is used.

[0107] The tire stopper 14A is disposed on the upper surface of the pallet main body 11A (pallet 10A) and on the right side of the front side of the pallet main body 11A. That is, for example, the tire stopper 14A is disposed on the side of the right front tire of the vehicle C. The tire stopper 14A includes a first rod-shaped member 141, a second rod-shaped member 142A, a third rod-shaped member 143, a plate-shaped member 151, and a second plate-shaped member 152. The tire stopper 14A is an example of a tire stopper for a pallet in the present invention.

[0108] As described above, the first rod-shaped member 141 has a cylindrical shape and is arranged along the short side direction (direction perpendicular to the entry direction) of the pallet main body 11A.

[0109] When the vehicle C is parked at a predetermined location on the pallet 10A (when the right front tire T of the vehicle C is placed at a predetermined position), the second rod-shaped member 142A restricts rearward (rearward in the approach direction) displacement of the tire T or forward (frontward in the approach direction) displacement of the tire T. The second rod-shaped member 142A also functions as an indicator of the stopping position of the vehicle C when the vehicle C is allowed to enter the pallet 10A. The space between the first rod-shaped member 141 and the second rod-shaped member 142A functions as the stopping position (first stopping position) of the tire T.

[0110] The second rod-shaped member 142A has a cylindrical shape and is arranged along the short side direction of the pallet body 11A. The second rod-shaped member 142A is made of the same steel material as the pallet body 11A. The second rod-shaped member 142A is arranged at a predetermined distance from the first rod-shaped member 141. The second rod-shaped member 142A is arranged parallel to the first rod-shaped member 141.

[0111] The first rod-shaped member 141 is disposed further forward than the second rod-shaped member 142A in the entry direction.

[0112] The third rod-shaped member 143 restricts rearward displacement of the tire T when the vehicle C is stopped at a predetermined position on the pallet 10A (when the right front tire T of the vehicle C is placed at a predetermined position). The third rod-shaped member 143 also functions as an indicator of the stopping position of the vehicle C when the vehicle C enters the pallet 10A. The space between the second rod-shaped member 142A and the third rod-shaped member 143 functions as a stopping position (second stopping position).

[0113] The third rod-shaped member 143 has a cylindrical shape and is arranged along the short side direction of the pallet body 11A. The third rod-shaped member 143 is made of the same steel material as the pallet body 11A. The third rod-shaped member 143 is arranged at a predetermined distance from the second rod-shaped member 142A. The third rod-shaped member 143 is arranged parallel to both the first rod-shaped member 141 and the second rod-shaped member 142A.

[0114] The diameter of the first rod-shaped member 141 is the same as the diameter of the second rod-shaped member 142A and the third rod-shaped member 143. The second rod-shaped member 142 is disposed forward of the third rod-shaped member 143 in the insertion direction. In other words, the second rod-shaped member 142A is disposed between the first rod-shaped member 141 and the third rod-shaped member 143 in the insertion direction.

[0115] The plate-like member 151 is disposed on and joined to the first rod-like member 141 and the upper surface of the pallet main body 11A (pallet 10A) between the first rod-like member 141 and the second rod-like member 142A. The plate-like member 151 is an inclined plate that slopes from the first rod-like member 141 to the upper surface of the pallet main body 11A (pallet 10A). That is, the inclination of the plate-like member 151 is an upward inclination with respect to the entry direction. The inclination of the plate-like member 151 is, for example, approximately 6 degrees. The plate-like member 151 is rectangular. The plate-like member 151 has a first joining side S1 and a second joining side S2 that are disposed opposite each other.

[0116] The first joining side S1 of the plate-shaped member 151 is joined to the upper part of the first rod-shaped member 141. The first joining side S1 is joined to the first rod-shaped member 141 by, for example, welding or bolts.

[0117] The second joining side S2 of the plate-like member 151 is joined to the upper surface of the pallet body 11. The second joining side S2 is joined to the upper surface of the pallet body 11 by, for example, welding or bolting.

[0118] The second joining side S2 of the plate-like member 151 is joined to the upper surface of the pallet body 11A in the vicinity of the second rod-like member 142A between the first rod-like member 141 and the second rod-like member 142A.

[0119] The second plate-shaped member 152 is disposed on and joined to the second rod-shaped member 142A and the upper surface of the pallet main body 11A (pallet 10A) between the second rod-shaped member 142A and the third rod-shaped member 143. The second plate-shaped member 152 is an inclined plate that slopes from the second rod-shaped member 142A to the upper surface of the pallet main body 11A (pallet 10A). That is, the inclination of the second plate-shaped member 152 is an upward inclination with respect to the entry direction. The inclination of the second plate-shaped member 152 is, for example, approximately 6 degrees. The second plate-shaped member 152 has a rectangular shape. The second plate-shaped member 152 has a first joint side S21 and a second joint side S22 that are disposed opposite each other.

[0120] The first joining side S21 of the second plate-shaped member 152 is joined to the upper part of the second rod-shaped member 142A. The first joining side S21 is joined to the second rod-shaped member 142A by, for example, welding or bolts. The first joining side S21 is an example of the 21st side in the present invention.

[0121] The second joining edge S22 of the second plate-shaped member 152 is joined to the upper surface of the pallet main body 11A. The second joining edge S22 is joined to the upper surface of the pallet main body 11A by, for example, welding or bolts. The second joining edge S22 is an example of the 22nd edge in the present invention.

[0122] The second joining edge S22 of the second plate-shaped member 152 is joined to the upper surface of the pallet body 11A in the vicinity of the third rod-shaped member 143, between the second rod-shaped member 142A and the third rod-shaped member 143. "In the vicinity of the third rod-shaped member 143" means a position closer to the third rod-shaped member 143 than the intermediate position between the second rod-shaped member 142A and the third rod-shaped member 143.

[0123] In this embodiment, the tire T of the vehicle C placed on the pallet 10A is placed at the first stop position or the second stop position. When the tire T is placed at the first stop position, the tire T abuts against the plate-shaped member 151. More preferably, when the tire T is placed at the first stop position, the tire T abuts against the plate-shaped member 151 and also against the second rod-shaped member 142A. When the tire T is placed at the second stop position, the tire T abuts against the second plate-shaped member 152. More preferably, when the tire T is placed at the second stop position, the tire T abuts against the second plate-shaped member 152 and also against the third rod-shaped member 143. The use example of the tire stopper 14A shown in FIG. 12 shows a state in which the tire T is placed at the second stop position.

[0124] ●Summary (2)● According to the embodiment described above, the pallet 10A included in the device 1 includes a tire stopper 14A. The tire stopper 14A includes a first rod-shaped member 141, a second rod-shaped member 142A, a third rod-shaped member 143, a plate-shaped member 151, and a second plate-shaped member 152. A first joint edge S1 of the plate-shaped member 151 is joined to an upper portion of the first rod-shaped member 141, and a second joint edge S2 of the plate-shaped member 151 is joined to the upper surface of the pallet main body 11 between the first rod-shaped member 141 and the second rod-shaped member 142A. A first joint edge S21 of the second plate-shaped member 152 is joined to an upper portion of the second rod-shaped member 142A, and a second joint edge S22 of the second plate-shaped member 152 is joined to the upper surface of the pallet main body 11A between the second rod-shaped member 142A and the third rod-shaped member 143. When the vehicle C is placed on the pallet 10A, the right front tire T of the vehicle C is placed at the first stop position or the second stop position. When the tire T is placed at the first stop position, the tire T is placed on the plate-like member 151. The inclined plate-like member 151 and the second rod-like member 142 restrict the displacement of the tire T in the front-rear direction. This allows the tire stopper 14A to prevent the vehicle C from falling off the pallet 10A.

[0125] Similarly, when the tire T is placed at the second stop position, the tire T is placed on the second plate-shaped member 152. The inclined second plate-shaped member 152 and the third rod-shaped member 143 restrict the displacement of the tire T in the front-rear direction. This allows the tire stopper 14A to prevent the vehicle C from falling off the pallet 10A.

[0126] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10A, the tire T of the vehicle C placed on the pallet 10A can be prevented from displacing forward by the inclined plate-like member 151 or the second plate-like member 152 more effectively than conventional tire stops.

[0127] Furthermore, as described above, when the vehicle C is placed on the pallet 10A, the right front tire T of the vehicle C is placed on the plate-shaped member 151 or the second plate-shaped member 152. In this case, the tire T may also come into contact with the second rod-shaped member 142 or the third rod-shaped member 143. That is, the tire T comes into contact at two points with the plate-shaped member 151 and the second rod-shaped member 142, or with the second plate-shaped member 152 and the third rod-shaped member 143. This increases the effect of restricting the displacement of the tire T in the front-rear direction.

[0128] Furthermore, according to the embodiment described above, the tire stopper 14A is configured with a first stop position and a second stop position, as described above. When the tire T of the vehicle C is placed at the first stop position, rearward acceleration or inertia occurs during the longitudinal transport of the pallet 10A, and even if the tire T goes over the second rod-shaped member 142A, the tire T will be placed at the second stop position. Therefore, the tire stopper 14A can further enhance the effect of preventing the vehicle C from falling off the pallet 10A.

[0129] Similarly, if the tire T of the vehicle C is placed at the second stop position, forward acceleration or inertia occurs during vertical transport of the pallet 10A, and even if the tire T goes over the second rod-shaped member 142A, the tire T will be placed at the first stop position. Therefore, the tire stopper 14A can further enhance the effect of preventing the vehicle C from falling off the pallet 10A.

[0130] The position where the tire stopper is arranged is not limited to the right side of the front side of the pallet body.

[0131] Furthermore, the third rod-shaped member may have a triangular prism or a square prism shape instead of a cylindrical shape.

[0132] Furthermore, the third rod-shaped member may be disposed on the pallet body via one or more support members disposed on the upper surface of the pallet body. That is, one or more support members corresponding to the third rod-shaped member are disposed on the upper surface of the pallet body, and the third rod-shaped member is disposed on the upper surface of the support member. In this case, the third rod-shaped member is joined to the upper surface of the pallet body together with the support member.

[0133] Furthermore, the second plate-shaped member may be joined to the pallet body via a reinforcing member between the lower surface (the surface facing the pallet body) of the second plate-shaped member and the upper surface of the pallet body. In this case, the upper surface of the pallet body is joined to the reinforcing member, and the lower surface of the second plate-shaped member is joined to the reinforcing member.

[0134] ●Modification of pallet tire stopper (2) A modified example of the tire stopper for a pallet according to the present invention will now be described.

[0135] Pallet tire stopper (2) variant (1) The tire chock for a pallet according to the present invention may be configured such that the first joining edge of the plate-shaped member is arranged on the upper surface of the pallet body, and the second joining edge of the plate-shaped member is arranged on the upper surface of the second rod-shaped member for joining. Similarly, the tire chock for a pallet according to the present invention may be configured such that the first joining edge of the second plate-shaped member is arranged on the upper surface of the pallet body, and the second joining edge of the second plate-shaped member is arranged on the upper surface of the third rod-shaped member for joining.

[0136] FIG. 13 is a schematic side view showing a modified example of the tire stopper. The tire stopper 14Ax is disposed on the upper surface of the pallet main body 11Ax (pallet 10Ax). The tire stopper 14Ax includes a first rod-shaped member 141x, a second rod-shaped member 142Ax, a third rod-shaped member 143x, a plate-shaped member 151x, and a second plate-shaped member 152x.

[0137] The figure shows that the plate-shaped member 151x is inclined relative to the approach direction and the second plate-shaped member 152x is inclined downward.

[0138] The plate-like member 151x is disposed on and joined to the second rod-like member 142Ax and the upper surface of the pallet main body 11Ax (pallet 10Ax) between the first rod-like member 141x and the second rod-like member 142Ax. The plate-like member 151x is an inclined plate that slopes from the second rod-like member 142Ax to the upper surface of the pallet main body 11Ax. That is, the inclination of the plate-like member 151x is downward with respect to the approach direction.

[0139] The first joining side S1x of the plate-shaped member 151x is joined to the upper surface of the pallet main body 11Ax, and the second joining side S2x of the plate-shaped member 151x is joined to the upper part of the second rod-shaped member 142Ax.

[0140] The second plate member 152x is disposed on and joined to the third rod-shaped member 143x and the upper surface of the pallet main body 11Ax (pallet 10Ax) between the second rod-shaped member 142Ax and the third rod-shaped member 143x. The second plate member 152x is an inclined plate that slopes from the third rod-shaped member 143x to the upper surface of the pallet main body 11Ax. That is, the slope of the second plate member 152x is downward with respect to the approach direction.

[0141] The first joining side S21x of the second plate-shaped member 152x is joined to the upper surface of the pallet main body 11Ax, and the second joining side S22x of the second plate-shaped member 152x is joined to the upper part of the third rod-shaped member 143x.

[0142] In the tire stopper 14Ax, when a vehicle (not shown) is placed on the pallet 10Ax, the tire (not shown) of the vehicle is placed at the first stop position or the second stop position and also placed on the plate-shaped member 151x or the second plate-shaped member 152x. When the tire is placed at the first stop position, the inclined plate-shaped member 151x and the first rod-shaped member 141x restrict the tire's displacement in the front-rear direction. Similarly, when the tire is placed at the second stop position, the inclined second plate-shaped member 152x and the second rod-shaped member 142Ax restrict the tire's displacement in the front-rear direction. This allows the tire stopper 14Ax to prevent the vehicle from falling off the pallet 10Ax.

[0143] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10Ax, the rearward displacement of the tires of the vehicle placed on the pallet 10Ax can be restricted more effectively by the inclined plate-like member 151x or the second plate-like member 152x than by conventional tire stops.

[0144] Pallet tire stopper (2) variant (2) 13, the tire stopper for the pallet according to the present invention may have a configuration in which the second plate member 152x and the plate member 151x are inclined downward with respect to the approach direction. However, the tire stopper for the pallet according to the present invention may have a configuration in which the second plate member is inclined downward with respect to the approach direction and the first plate member is inclined upward with respect to the approach direction.

[0145] Pallet tire stopper (2) modified version (3) 11, the third rod-shaped member is disposed rearward of the second rod-shaped member in the approach direction. However, in the present invention, the third rod-shaped member may be disposed forward of the first rod-shaped member in the approach direction.

[0146] FIG. 14 is a schematic side view showing a modified example of the tire stopper. The tire stopper 14Ay is disposed on the upper surface of the pallet main body 11Ay (pallet 10Ay). The tire stopper 14Ay includes a first rod-shaped member 141y, a second rod-shaped member 142Ay, a third rod-shaped member 143y, a plate-shaped member 151y, and a second plate-shaped member 152y.

[0147] This figure shows that the third rod-shaped member 143y is disposed in front of the first rod-shaped member 141y with respect to the approach direction, and the second plate-shaped member 152y is inclined downward.

[0148] The first rod-shaped member 141y is disposed in front of the second rod-shaped member 142Ay in the approach direction.

[0149] The plate-like member 151y is disposed on and joined to the first rod-like member 141y and the upper surface of the pallet main body 11Ay (pallet 10Ay) between the first rod-like member 141y and the second rod-like member 142Ay. The plate-like member 151y is an inclined plate that slopes from the first rod-like member 141y to the upper surface of the pallet main body 11Ay. That is, the inclination of the plate-like member 151y is an upward slope with respect to the approach direction.

[0150] The first joining side S1y of the plate-shaped member 151y is joined to the upper part of the first rod-shaped member 141y, and the second joining side S2y of the plate-shaped member 151y is joined to the upper surface of the pallet main body 11Ay.

[0151] The third rod-shaped member 143y is disposed in front of the first rod-shaped member 141y in the entry direction. That is, the first rod-shaped member 141y is disposed between the second rod-shaped member 142Ay and the third rod-shaped member 143y. The space between the first rod-shaped member 141y and the third rod-shaped member 143y functions as a second stop position.

[0152] The second plate member 152y is disposed on and joined to the first rod-shaped member 141y and the upper surface of the pallet main body 11Ay (pallet 10Ay) between the first rod-shaped member 141y and the third rod-shaped member 143y. The second plate member 152y is an inclined plate that slopes from the first rod-shaped member 141y to the upper surface of the pallet main body 11Ay. That is, the slope of the second plate member 152y is downward with respect to the approach direction.

[0153] The first joining side S21y of the second plate-shaped member 152y is joined to the upper surface of the pallet main body 11Ay, and the second joining side S22y of the second plate-shaped member 152y is joined to the upper part of the first rod-shaped member 141y.

[0154] In the tire stopper 14Ay, when a vehicle (not shown) is placed on the pallet 10Ay, the vehicle's tire (not shown) is placed at the first stop position or the second stop position, and the tire is placed on the plate-shaped member 151y or the second plate-shaped member 152y. When the tire is placed at the first stop position, the inclined plate-shaped member 151y and the second rod-shaped member 142Ay restrict the tire's displacement in the front-rear direction. Similarly, when the tire is placed at the second stop position, the inclined second plate-shaped member 152y and the third rod-shaped member 143y restrict the tire's displacement in the front-rear direction. This allows the tire stopper 14Ay to prevent the vehicle from falling off the pallet 10Ay.

[0155] In particular, even if acceleration or inertia occurs during vertical transport of the pallet 10Ay, the inclined plate-like member 151y can prevent the tires of the vehicle placed on the pallet 10Ay from displacing forward more effectively than conventional tire stops. Also, the second plate-like member 152y can prevent the tires of the vehicle placed on the pallet 10Ay from displacing backward more effectively than conventional tire stops.

[0156] Pallet tire stopper (2) modified version (4) In the present invention, the diameters of the rod-shaped members may be different from each other, or only one rod-shaped member may be different from the other two rod-shaped members. That is, for example, the diameter of the first rod-shaped member may be larger than the diameter of the second rod-shaped member, which may be larger than the diameter of the third rod-shaped member.

[0157] ●Modification (5) of tire stopper (2) In the present invention, the inclination direction of each of the plate-shaped member and the second plate-shaped member may be either an upward inclination or a downward inclination. [Explanation of symbols]
