[0008] The following describes one embodiment of a parking system and a gate system for a parking system, with reference to Figures 1 to 11. Note that in each figure (and similarly in Figures 12 and 13), the dimensional ratios in the drawings do not necessarily match the actual dimensional ratios, nor do the dimensional ratios between the drawings necessarily match.

[0009] As shown in Figures 1 and 2, the parking device 1 may, for example, include a pallet 2 on which a vehicle X1 is placed, a pallet drive device (not shown) for moving the pallet 2, and a parking device gate device (hereinafter also simply referred to as "gate device") 1a that separates the storage space for storing the vehicle X1 placed on the pallet 2 from the external space which is outside the storage space.

[0010] Although not particularly limited, in the present embodiment, the pallet 2 is configured to be movable at a position above a reference position (for example, the ground) X2. For example, a pit recessed downward with respect to the reference position X2 may be provided, and the pallet 2 may be configured to be movable not only above but also below the reference position X2.

[0011] For example, a plurality (two in FIGS. 1 and 2) of the pallets 2 may be arranged in the vertical direction D3. In addition, for example, a plurality of the pallets 2 may be arranged in the first lateral direction D1, and also, for example, a plurality of the pallets 2 may be arranged in the second lateral direction D2. Then, for example, by moving the pallet 2, a desired vehicle X1 can exit from the pallet 2 or enter a desired pallet 2.

[0012] In the present embodiment, the second lateral direction D2 is the direction in which the vehicle X1 enters and exits with respect to the pallet 2, and the first lateral direction D1 is a lateral direction orthogonal to the second lateral direction D2. Hereinafter, the lateral directions D1 and D2 may be defined based on the vehicle X1 placed on the pallet 2. For example, the first lateral direction D1 is also referred to as the left - right direction, and the second lateral direction D2 is also referred to as the front - rear direction.

[0013] Also, in each figure, among the first lateral direction D1, the direction of the arrow is also referred to as the left direction, and the direction opposite to the direction of the arrow among the first lateral direction D1 is also referred to as the right direction. Also, in each figure, among the second lateral direction D2, the direction of the arrow is also referred to as the front direction, and the direction opposite to the direction of the arrow among the second lateral direction D2 is also referred to as the rear direction.

[0014] The gate device 1a may include, for example, as in the present embodiment, a pair of columns 3 and 4 arranged apart in the first lateral direction D1, gates 5 and 6 arranged between the pair of columns 3 and 4, a lifting device 7 for moving the gates 5 and 6 in the vertical direction D3 with respect to the columns 3 and 4, a rail 8 for guiding the gates 5 and 6 in the vertical direction D3, and a support portion 9 for supporting the gate 6 from below.

[0015] Gates 5 and 6 may be arranged along the first horizontal direction D1 and the vertical direction D3, for example, as in this embodiment. Also, although not particularly limited, two gates 5 and 6 are provided in this embodiment. Specifically, gates 5 and 6 include a first gate (also referred to as a "lower gate") 5 and a second gate (also referred to as an "upper gate") 6 disposed above the first gate 5. Note that, for example, only one gate 5 and 6 may be provided, or, for example, three or more gates 5 and 6 may be provided.

[0016] The lifting device 7 may include, for example, as in this embodiment, a rope (e.g., a wire, a chain, etc.) 7a connected to the first gate 5, strut sheaves 7b and 7b wound around the rope 7a and rotatably connected to the second strut 4, and a driving device 7c that drives the rope 7a to move the gates 5 and 6.

[0017] The lifting device 7 may include, for example, as in this embodiment, a rope fixing portion 7d that fixes the first end portion of the rope 7a to the first strut 3, and gate sheaves 7e and 7e wound around the rope 7a and rotatably connected to the first gate 5. Thereby, the first gate 5 is connected to the rope 7a via the gate sheaves 7e and 7e. Note that the first gate 5 may be connected to the rope 7a by fixing the first end portion of the rope 7a to the first gate 5.

[0018] Also, the driving device 7c is not particularly limited, but in this embodiment, it is a winding device that winds up the second end portion of the rope 7a. Note that the winding device may be driven electrically, for example, or may be driven manually, for example. Also, the lifting device 7 may include, for example, a weight fixed to the second end portion of the rope 7a, and the driving device 7c may be a motor that gives rotational drive to the strut sheave 7b.

[0019] Furthermore, the drive unit 7c may be located near the middle of the second support column 4, as in this embodiment, or it may be located near the lower or upper end of the second support column 4. Also, the drive unit 7c may be attached to the second support column 4, as in this embodiment, or it may be installed on the ground (for example, at the reference position X2).

[0020] Then, the first gate 5 is raised by the lifting device 7, and for example, the upper end of the first gate 5 engages with the upper end of the second gate 6, causing the second gate 6 to rise together with the first gate 5. As a result, as shown in Figure 2, the gates 5 and 6 are in the open position, and the gate device 1a is in an open state, allowing the vehicle X1 to enter and exit.

[0021] Furthermore, as the first gate 5 is lowered by the lifting device 7, for example, the upper end of the second gate 6 engages with the upper end of the first gate 5, so the second gate 6 also lowers together with the first gate 5. Subsequently, as the second gate 6 is supported from below by the support part 9, only the first gate 5 lowers. As a result, as shown in Figure 1, gates 5 and 6 are in the closed position, and the gate device 1a becomes closed, making it impossible for the vehicle X1 to enter or exit.

[0022] Thus, in this embodiment, the gate device 1a opens when gates 5 and 6 rise, and closes when gates 5 and 6 descend. Alternatively, for example, the gate device 1a may open when gates 5 and 6 descend below the reference position X2, and close when gates 5 and 6 rise.

[0023] The support columns 3 and 4 may extend vertically in a direction D3 from the open position to the closed position of the gates 5 and 6. The rail 8 may also extend vertically in a direction D3 from the open position to the closed position of the gates 5 and 6 and be fixed to the support columns 3 and 4.

[0024] The first gate 5 may, for example, as in this embodiment, comprise a first gate body 5a, a first guide portion 10 connected to the first gate body 5a and guided by the rail 8, and a second guide portion 11 connected to the first gate body 5a at a position above the first guide portion 10 and guided by the rail 8. The first gate body 5a may, for example, be composed of a plate and a frame fixed to the plate.

[0025] The second gate 6 may, for example, comprise a second gate body 6a and a third guide portion 6b connected to the second gate body 6a and guided by the rail 8, as in this embodiment. The second gate body 6a may, for example, be composed of a plate and a frame fixed to the plate.

[0026] Furthermore, for example, as in this embodiment, the first gate 5 may be configured such that it has a gate rail 5b that extends in the vertical direction D3 and is fixed to the first gate body 5a, and the second gate 6 has a fourth guide portion 6c that is guided by the gate rail 5b. The fourth guide portion 6c may be connected to the second gate body 6a at a position located below the third guide portion 6b.

[0027] As a result, when the first gate 5 moves in the vertical direction D3, the first and second guide sections 10 and 11 are guided by the rail 8, and when the second gate 6 moves in the vertical direction D3, the third guide section 6b is guided by the rail 8, and the fourth guide section 6c is guided by the gate rail 5b.

[0028] Therefore, for example, gates 5 and 6 can be stably moved in the vertical direction D3. Note that each guide section 6b, 6c, 10, 11 and each rail 5b, 8 may be provided in pairs, for example, as in this embodiment, so as to be symmetrical at the center of the first lateral direction D1 of gates 5 and 6.

[0029] In gates 5 and 6, the number of guide sections 10, 11, and 6b that guide a single common rail 8 is not particularly limited. In this embodiment, the number of guide sections 10, 11, and 6b that guide a single common rail 8 is three, but for example, there may be one, two, or four or more.

[0030] Furthermore, in this embodiment, the number of guide sections 10 and 11 that guide a single rail 8 in the first gate 5 is two, but it may be one or three or more. Also, in this embodiment, the number of guide sections 6b that guide a single rail 8 in the second gate 6 is one, but it may be two or more.

[0031] As shown in Figures 3 and 4, the support column 3 may, for example, include a flat plate-shaped base portion 3a extending in the second lateral direction D2, a flat plate-shaped first reinforcing portion 3b extending from the first end of the base portion 3a toward the gates 5 and 6 in the first lateral direction D1 (i.e., toward the second support column 4), and a flat plate-shaped second reinforcing portion 3c extending from the second end of the base portion 3a toward the gates 5 and 6 in the first lateral direction D1 (i.e., toward the second support column 4).

[0032] As a result, the base portion 3a has an inner surface 3d facing the gates 5 and 6 side (i.e., the second support column 4 side) in the first lateral direction D1, the first reinforcing portion 3b has a first reinforcing inner surface 3e facing the inner surface 3d side (i.e., the second reinforcing portion 3c side) in the second lateral direction D2, and the second reinforcing portion 3c has a second reinforcing inner surface 3f facing the inner surface 3d side (i.e., the first reinforcing portion 3b side) in the second lateral direction D2.

[0033] Furthermore, the support column 3 may also include, for example, a third reinforcing portion 3g extending in a flat plate shape in the first lateral direction D1 from the first end of the base portion 3a on the side opposite to the first reinforcing portion 3b, and a fourth reinforcing portion 3h extending in a flat plate shape in the first lateral direction D1 from the second end of the base portion 3a on the side opposite to the second reinforcing portion 3c. As a result, the support column 3 is formed in an H shape when viewed in the vertical direction D3.

[0034] The support column 3 may, for example, be composed of a base portion 3a and first and second reinforcing portions 3b, 3c, and be formed in a C-shape when viewed in the vertical direction D3 (see Figures 12 and 13). Alternatively, the support column 3 may be composed of a base portion 3a and first and third reinforcing portions 3b, 3g, and be formed in a T-shape when viewed in the vertical direction D3. Alternatively, the support column 3 may be composed of a base portion 3a and a first reinforcing portion 3b, and be formed in an L-shape when viewed in the vertical direction D3.

[0035] The reinforcing inner surfaces 3e and 3f may overlap with the ends of gates 5 and 6 in a second lateral view D2, as in this embodiment. Specifically, the first and second guide portions 10 and 11 of the first gate 5 and the third guide portion 6b of the second gate 6 may overlap with the reinforcing inner surfaces 3e and 3f in at least a portion of a second lateral view D2, as in this embodiment.

[0036] The configuration of the second support column 4 is not particularly limited. Although not shown in the diagram, the second support column 4 may be configured, for example, at the center of the first lateral direction D1 of gates 5 and 6, so as to be symmetrical to the configuration of the first support column 3.

[0037] As shown in Figures 3 to 6, the gate device 1a may include, for example, a first detection unit 1b for detecting gates 5 and 6, as in this embodiment. The first detection unit 1b may include, for example, a first sensor 12 for detecting that gates 5 and 6 are in the open position (Figure 2), and a first fixing means 13 for fixing the first sensor 12 to the first support column 3, as in this embodiment.

[0038] Furthermore, the first fixing means 13 may, for example, fix the first sensor 12 to the first reinforcing inner surface 3e, as in this embodiment. Also, although not particularly limited, the first sensor 12 may, for example, detect the first guide portion 10 when the gates 5 and 6 are in the open position, as in this embodiment.

[0039] The guide sections 10 and 11 of the first gate 5, that is, the first and second guide sections 10 and 11, may each include, for example, as in this embodiment, a fixing section 10a, 11a fixed to the first gate body 5a, shafts 10b, 11b connected to the fixing sections 10a, 11a and extending in the second lateral direction D2, and rollers 10c, 11c rotatable around the shafts 10b, 11b.

[0040] For example, the shafts 10b and 11b may be fixed to the fixed parts 10a and 11a, and the rollers 10c and 11c may be rotatable around the shafts 10b and 11b by being rotatably connected to the shafts 10b and 11b. Alternatively, for example, the shafts 10b and 11b and the rollers 10c and 11c may be integrally constructed, and the shafts 10b and 11b may be rotatable around the shafts 10b and 11b by being rotatably connected to the fixed parts 10a and 11a.

[0041] Furthermore, as in this embodiment, the roller 10c of the first guide section 10 and the roller 11c of the second guide section 11 may have the same shape and be positioned at the same location in the vertical direction D3 view. Although not shown in the figures, for example, the third guide section 6b of the second gate 6 may be equipped with a roller, and the roller of the third guide section 6b may have the same shape as the rollers 10c and 11c of the first and second guide sections 10 and 11 and be positioned at the same location in the vertical direction D3 view.

[0042] The first guide portion 10 may, for example, include a projection 10e extending from the shaft 10b in the second lateral direction D2, as in this embodiment. Furthermore, the projection 10e may be configured such that its projection length from the shaft 10b can be changed by including a threaded portion (for example, a male threaded portion) that engages with the shaft 10b.

[0043] The rail 8 may, for example, include a restricting portion 8a that strikes the guide portions 10 and 11 in the second lateral direction D2, and a fixing portion 8b that fixes the restricting portion 8a to the first support column 3 (inner surface 3d of the base), as in this embodiment. The rail 8 may be separate from the support columns 3 and 4 and fixed to them, as in this embodiment, or the rail 8 may be an integral member (for example, a single steel material) with the support columns 3 and 4, with part of the member forming the support columns 3 and 4 and the other part forming the rail 8.

[0044] Alternatively, for example, as in this embodiment, the rollers 10c and 11c may be provided with grooves 10d and 11d extending around the entire circumference of their outer periphery, and the restricting portion 8a may protrude in a plate-like manner in the first lateral direction D1 and be positioned inside the grooves 10d and 11d of the rollers 10c and 11c. As a result, the restricting portion 8a comes into contact with the rollers 10c and 11c in the second lateral direction D2, thereby restricting the movement of the guide portions 10 and 11 in the second lateral direction D2.

[0045] Furthermore, as in this embodiment, the rail 8 (e.g., the restricting portion 8a) may be arranged so as to contact the rollers 10c and 11c not only in the second lateral direction D2 but also in the first lateral direction D1. As a result, the rail 8 (e.g., the restricting portion 8a) fixed to the first support column 3 and the rail 8 (e.g., a restricting portion not shown) fixed to the second support column 4 cooperate to restrict the movement of the guide portions 10 and 11 not only in the second lateral direction D2 but also in the first lateral direction D1.

[0046] The first fixing means 13 is not particularly limited, but may include, for example, a bracket 13a fixed to the first reinforcing inner surface 3e of the first support column 3, and screw members (e.g., bolts) 13b, 13b for fastening the first sensor 12 to the bracket 13a. The bracket 13a may also have elongated holes 13c, 13c that extend in the vertical direction D3 and are inserted into the screw members 13b.

[0047] This allows the vertical position D3 of the first sensor 12 to be changed by changing the vertical position D3 of the screw member 13b relative to the elongated hole 13c. While not particularly limited, the screw member 13b may, for example, fasten the first sensor 12 to the bracket 13a by screwing it into the female thread of the first sensor 12.

[0048] A portion of the first sensor 12 may overlap with the first and second reinforcing inner surfaces 3e and 3f in a second lateral view D2, as in this embodiment. Also, at least a portion of the first sensor 12 may be positioned between the gates 5 and 6 and the first reinforcing inner surface 3e in a vertical view D3, as in this embodiment. Specifically, at least a portion of the first sensor 12 may be positioned between the guide portions 6b, 10, and 11 and the first reinforcing inner surface 3e in a vertical view D3, as in this embodiment.

[0049] This allows for the effective use of spaces that previously did not have components placed in them, such as the space overlapping with the reinforcing inner surfaces 3e and 3f in the second lateral view D2, or the space between the gates 5 and 6 (guide sections 6b, 10, and 11) and the first reinforcing inner surface 3e. While not particularly limited, the distance in the second lateral direction D2 between the rollers 10c and 11c and the first reinforcing inner surface 3e in the vertical view D3 may be, for example, 100 mm or less, or for example, 50 mm or less.

[0050] The first sensor 12 may, for example, as in this embodiment, comprise a first sensor body 12a fixed to the first support column 3, and a first detector 12b movably connected to the first sensor body 12a and in contact with the first guide portion 10. As a result, the position of the first guide portion 10 is detected when the first guide portion 10 contacts the first detector 12b and the first detector 12b moves relative to the first sensor body 12a.

[0051] Furthermore, since the first guide portion 10 is restricted from moving in the second lateral direction D2 by the restricting portion 8a of the rail 8, the first sensor 12 can reliably detect the position of the first guide portion 10. The first detector 12b may be rotatably connected to the first sensor body 12a, for example, as in this embodiment.

[0052] Furthermore, the first sensor 12 is equipped with a detection area capable of detecting the first guide portion 10. Specifically, in this embodiment, the detection area of ​​the first sensor 12 is the area where the first detector element 12b is located.

[0053] In this embodiment, since the first sensor 12 is positioned approximately midway along the first support column 3, as the gates 5 and 6 move vertically in the D3 direction between the open and closed positions, the first to third guide sections 10, 11, and 6b are positioned in a location that overlaps with the first detector 12b (detection area) in the second horizontal view D2 direction. That is, each region in which the first to third guide sections 10, 11, and 6b move vertically in the D3 direction includes a position that overlaps with the first detector 12b (detection area) in the second horizontal view D2 direction.

[0054] Therefore, as shown in Figure 3, in the first guide section 10, the roller 10c and the shaft 10b are each separated from the first detector 12b (detection area) in the vertical direction D3 view, while the protruding section 10e may overlap with the first detector 12b (detection area) in the vertical direction D3 view. As a result, the first guide section 10 is arranged to overlap with the first detector 12b (detection area) in the vertical direction D3 view.

[0055] On the other hand, as shown in Figure 4, in the second guide section 11, the roller 11c and the shaft 11b may each be separated from the first detector 12b (detection area) when viewed in the vertical direction D3. As a result, the second guide section 11 is positioned so as to be separated from the first detector 12b (detection area) when viewed in the vertical direction D3. Although not shown, the third guide section 6b may also be separated from the first detector 12b (detection area) when viewed in the vertical direction D3.

[0056] Here, the detection operation of the first sensor 12 will be explained with reference to Figures 6 to 8.

[0057] When gates 5 and 6 are in the open position (Figure 2), as shown in Figure 6, the first guide portion 10 overlaps with the first detector 12b in the second lateral view D2. As a result, the protrusion 10e of the first guide portion 10 comes into contact with the first detector 12b, and the first detector 12b moves to the detection position. Consequently, the first sensor 12 detects the first guide portion 10, and therefore the first sensor 12 detects that gates 5 and 6 are in the open position.

[0058] As gates 5 and 6 descend from the open position, the protruding portion 10e of the first guide portion 10 moves away from the first detector 12b, as shown in Figure 7, and the first detector 12b returns to the standby position. As a result, the first sensor 12 does not detect the first guide portion 10, and therefore the first sensor 12 detects that gates 5 and 6 are not in the open position.

[0059] Furthermore, as gates 5 and 6 descend further, the second guide section 11 overlaps with the first detector 12b in the second lateral view D2, as shown in Figure 8. However, because the second guide section 11 is separated from the first detector 12b, the first detector 12b remains in its standby position without moving. As a result, the first sensor 12 does not detect the second guide section 11.

[0060] Therefore, the first sensor 12 detects only the first guide portion 10. As a result, the first sensor 12 can accurately detect that the gates 5 and 6 are in the open position. Furthermore, since the first sensor 12 can be positioned at a desired location regardless of the positions of the first and second guide portions 10 and 11, the placement of the first sensor 12 can be made flexible.

[0061] Although not shown in the diagram, the third guide section 6b also overlaps with the first detector 12b in the second lateral view D2. However, because the third guide section 6b, like the second guide section 11, is separated from the first detector 12b, the first detector 12b remains in its standby position without moving. As a result, the first sensor 12 does not detect the third guide section 6b.

[0062] Thus, in this embodiment, the first sensor 12 detects the vertical movement D3 of the first guide portion 10, which is directly guided by the rail 8 fixed to the support column 3, while not detecting the second and third guide portions 11 and 6b, which are also directly guided by the rail 8 fixed to the support column 3. Furthermore, since the movement of each guide portion 10, 11, and 6b in the first and second lateral directions D1 and D2 is restricted by the rail 8 (restricting portion 8a), for example, the position of the first sensor 12 can be easily adjusted.

[0063] Furthermore, as shown in Figures 9 and 10, the gate device 1a may also include a second detection unit 1c for detecting gates 5 and 6, as in this embodiment. The second detection unit 1c may include a second sensor 14 for detecting that gates 5 and 6 are in the closed position (Figure 1), and a second fixing means 15 for fixing the second sensor 14 to the first support column 3.

[0064] Furthermore, the second fixing means 15 may, for example, fix the second sensor 14 to the first reinforcing inner surface 3e, as in this embodiment. Also, although not particularly limited, the second sensor 14 may, for example, detect the first guide portion 10 when the gates 5 and 6 are in the closed position, as in this embodiment.

[0065] The configuration of the second fixing means 15 is not particularly limited. For example, the second fixing means 15 may include a bracket 15a having an elongated hole (not shown in Figures 9 and 10) and a screw member 15b, similar to the first fixing means 13. Also, the configuration of the second fixing means 15 may differ from that of the first fixing means 13, for example.

[0066] A portion of the second sensor 14 may overlap with the first and second reinforcing inner surfaces 3e and 3f in a second lateral view D2, as in this embodiment. Alternatively, a portion of the second sensor 14 may be positioned between the first gate 5 and the first reinforcing inner surface 3e in a vertical view D3, as in this embodiment.

[0067] Specifically, a portion of the second sensor 14 may be positioned between the first guide portion 10 and the first reinforcing inner surface 3e in a vertical view D3, as in this embodiment. This allows for effective utilization of spaces that overlap with the reinforcing inner surfaces 3e and 3f in a second horizontal view D2, and the space between the first gate 5 (first guide portion 10) and the first reinforcing inner surface 3e.

[0068] The second sensor 14 may, for example, as in this embodiment, comprise a second sensor body 14a fixed to the first support column 3, and a second detector 14b movably connected to the second sensor body 14a and in contact with the first guide portion 10. As a result, the position of the first guide portion 10 is detected when the first guide portion 10 contacts the second detector 14b and the second detector 14b moves relative to the second sensor body 14a.

[0069] Furthermore, since the first guide portion 10 is restricted from moving in the second lateral direction D2 by the restricting portion 8a of the rail 8, the second sensor 14 can reliably detect the position of the first guide portion 10. The second detector 14b may be rotatably connected to the second sensor body 14a, for example, as in this embodiment.

[0070] Furthermore, for example, as in this embodiment, the second sensor body 14a may be configured such that, in the first lateral view D1, the second sensor body 14a is separated from the restricting portion 8a of the rail 8, while the second detector 14b extends from the second sensor body 14a in the second lateral direction D2 so as to overlap with the restricting portion 8a of the rail 8 in the first lateral view D1. This ensures that the roller 10c is always positioned at the location of the restricting portion 8a, thereby ensuring that the roller 10c makes reliable contact with the second detector 14b.

[0071] The second sensor 14 has a detection area capable of detecting the first guide portion 10. Specifically, in this embodiment, the detection area of ​​the second sensor 14 is the area where the second detector 14b is located. In this embodiment, the second sensor 14 is located near the lower end of the first support column 3, that is, near the reference position X2.

[0072] As a result, gates 5 and 6 move vertically D3 between the open and closed positions, causing the first guide unit 10 to be positioned in a location that overlaps with the second detector 14b (i.e., the detection area) in the second horizontal view D2. That is, the region in which the first guide unit 10 moves vertically D3 includes the position that overlaps with the second detector 14b (detection area) in the second horizontal view D2.

[0073] Furthermore, in the first guide section 10, for example, the roller 10c may overlap with the second detector 14b (detection area) in the vertical direction D3 view. As a result, the first guide section 10 overlaps with the second detector 14b (detection area) in the vertical direction D3 view.

[0074] On the other hand, as gates 5 and 6 move vertically in the D3 direction between the open and closed positions, the second and third guide parts 11 and 6b are not positioned in a location that overlaps with the second detector 14b (i.e., the detection area) in the second lateral view in the D2 direction. In other words, the region in which the second and third guide parts 11 and 6b move vertically in the D3 direction does not include a location that overlaps with the second detector 14b (detection area) in the second lateral view in the D2 direction.

[0075] Although not shown in the diagram, in the second and third guide sections 11 and 6b, for example, the roller 10c may overlap with the second detector 14b (detection area) in the vertical direction D3 view. As a result, the second and third guide sections 11 and 6b overlap with the second detector 14b (detection area) in the vertical direction D3 view.

[0076] Here, the detection operation of the second sensor 14 will be explained with reference to Figures 10 and 11.

[0077] When gates 5 and 6 are in the closed position (Figure 1), as shown in Figure 10, the first guide portion 10 overlaps with the second detector 14b in the second lateral view D2. As a result, the roller 10c of the first guide portion 10 comes into contact with the second detector 14b, and the second detector 14b moves to the detection position. Consequently, the second sensor 14 detects the first guide portion 10, and the second sensor 14 detects that gates 5 and 6 are in the closed position.

[0078] Then, as the second gate 6 rises, and subsequently the first gate 5 rises from the closed position, the roller 10c of the first guide unit 10 moves away from the second detector 14b, as shown in Figure 11, and the second detector 14b returns to the standby position. As a result, the second sensor 14 does not detect the first guide unit 10, and the second sensor 14 detects that the gates 5 and 6 are not in the closed position.

[0079] Thus, in this embodiment, the second sensor 14 detects the vertical movement D3 of the first guide portion 10, which is directly guided by the rail 8 fixed to the support column 3. Furthermore, since the first guide portion 10 is restricted from moving in the first and second lateral directions D1 and D2 by the rail 8 (restricting portion 8a), for example, the position of the second sensor 14 can be easily adjusted.

[0080] Based on the above, as in this embodiment, the parking device 1 is equipped with the aforementioned parking device gate device 1a.

[0081] Furthermore, as in this embodiment, the parking gate device 1a preferably comprises support columns 3 and 4 extending in the vertical direction D3, gates 5 and 6 arranged along the vertical direction D3 and the first horizontal direction D1 and moving in the vertical direction D3, and detection units 1b and 1c for detecting the position of the gate (first gate in this embodiment) 5, wherein the detection units 1b and 1c are fixed to the support column (first support column in this embodiment) 3.

[0082] With this configuration, the detection units 1b and 1c are fixed to the support column 3, and the position of the gate 5 can be detected by the detection units 1b and 1c.

[0083] Furthermore, in the parking gate device 1a as in this embodiment, the support column 4 comprises a base portion 3a extending in the second lateral direction D2 and a reinforcing portion 3b extending from the base portion 3a toward the gates 5 and 6 in the first lateral direction D1, the base portion 3a has a base inner surface 3d facing toward the gates 5 and 6 in the first lateral direction D1, the reinforcing portion 3b has a reinforcing inner surface 3e facing toward the base inner surface 3d in the second lateral direction D2, and the detection units 1b and 1c are preferably fixed to at least one of the base inner surface 3d and the reinforcing inner surface 3e (in this embodiment, the first reinforcing inner surface) 3e.

[0084] With this configuration, the support column 4 is equipped with a base inner surface 3d and a reinforcing inner surface 3e, and the detection units 1b and 1c are fixed to at least one of the base inner surface 3d and the reinforcing inner surface 3e. The position of the gate 5 can then be detected by the detection units 1b and 1c.

[0085] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the gates 5 and 6 are arranged such that their ends overlap with the reinforcing inner surface 3e in the second lateral view D2, and that the detection units 1b and 1c are equipped with sensors 12 and 14 for detecting the position of the gates 5 and 6, and that at least a portion of the sensors 12 and 14 are arranged such that they overlap with the reinforcing inner surface 3e in the second lateral view D2.

[0086] With this configuration, the sensors 12 and 14 are arranged such that at least a portion of them overlap with the reinforced inner surface 3e in the second lateral direction D2 view, and the space that overlaps with the reinforced inner surface 3e in the second lateral direction D2 view can be effectively utilized.

[0087] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that at least a portion of the sensors 12 and 14 are positioned between the reinforcing inner surface 3e and the gates 5 and 6 in a vertical D3 view.

[0088] With this configuration, at least a portion of the sensors 12 and 14 are positioned between the reinforced inner surface 3e and the gates 5 and 6 in the vertical direction D3 view, so the space between the reinforced inner surface 3e and the gates 5 and 6 in the vertical direction D3 view can be effectively utilized.

[0089] Furthermore, as in this embodiment, the parking gate device 1a further comprises a rail 8 that extends in the vertical direction D3 to guide the gate 5 in the vertical direction D3 and is fixed to the support column 3, the gate 5 comprises guide portions 10 and 11 that are guided by the rail 8, the rail 8 comprises a restricting portion 8a that strikes the guide portions 10 and 11 in the predetermined horizontal direction D2 to restrict the movement of the guide portions 10 and 11 in a predetermined horizontal direction (second horizontal direction in this embodiment) D2, and the detection units 1b and 1c detect the position of the guide portion (first guide portion in this embodiment) 10, which is a preferred configuration.

[0090] With this configuration, the restricting portion 8a of the rail 8 contacts the guide portions 10 and 11 in a predetermined lateral direction D2, thereby restricting the movement of the guide portions 10 and 11 in that predetermined lateral direction D2. Furthermore, since the sensors 12 and 14 detect the position of the guide portion 10, the position of the gate 5 can be reliably detected by the sensors 12 and 14.

[0091] Furthermore, as in this embodiment, in the parking gate device 1a, the guide portion (first guide portion in this embodiment) 10 comprises an axis 10b extending in the predetermined lateral direction (second lateral direction in this embodiment) D2 and a roller 10c rotatable around the axis 10b, the roller 10c comprises a groove 10d extending around the entire circumference of its outer periphery, the regulating portion 8a is positioned inside the groove 10d so as to contact the roller 10c in the predetermined lateral direction D2, and the detection portion (second detection portion in this embodiment) 1c is a sensor fixed to the support column 3. The sensor comprises a main body (in this embodiment, a second sensor body) 14a and a detector (in this embodiment, a second detector) 14b that is movably connected to the sensor body 14a and detects the position of the guide portion 10 by contacting the guide portion 10. Preferably, the sensor body 14a is positioned away from the regulating portion 8a in a lateral direction (in this embodiment, a first lateral direction) D1 view perpendicular to the predetermined lateral direction D2, and the detector 14b extends from the sensor body 14a so as to overlap with the regulating portion 8a in the perpendicular lateral direction D1 view.

[0092] With this configuration, the guide portion 10 contacts the detector 14b, causing the detector 14b to move relative to the sensor body 14a, thereby enabling the detection of the guide portion 10's position. Furthermore, while the restricting portion 8a is positioned inside the groove 10d of the roller 10c, the detector 14b extends from the sensor body 14a, so that the detector 14b overlaps with the restricting portion 8a in a perpendicular lateral view D1. This ensures that the roller 10c makes reliable contact with the detector 14b.

[0093] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the detection unit (first detection unit in this embodiment) 1b has a detection area capable of detecting the guide unit 10, the guide units 10 and 11 include first and second guide units 10 and 11 that are separated in the vertical direction D3, and each of the areas in which the first and second guide units 10 and 11 move in the vertical direction D3 includes a position that overlaps with the detection area in the predetermined horizontal direction (second horizontal direction in this embodiment) D2 view, the first guide unit 10 is arranged to overlap with the detection area in the vertical direction D3 view, and the second guide unit 11 is arranged to be separated from the detection area in the vertical direction D3 view.

[0094] With this configuration, each region in which the first and second guide sections 10 and 11 move in the vertical direction D3 includes a position that overlaps with the detection region in a predetermined horizontal direction D2 view. Since the first guide section 10 overlaps with the detection region of the detection section 1b in the vertical direction D3 view, the detection section 1b can detect the first guide section 10 when it is positioned in a position that overlaps with the detection region in a predetermined horizontal direction D2 view.

[0095] On the other hand, since the second guide section 11 is separated from the detection area of ​​the detection section 1b in the vertical direction D3 view, when the second guide section 11 is positioned to overlap with the detection area in the second horizontal direction D2 view, the detection section 1b does not detect the second guide section 11. As a result, only the first guide section 10 can be detected by the detection section 1b.

[0096] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the first and second guide sections 10 and 11 each include shafts 10b and 11b and rollers 10c and 11c that can rotate around the shafts 10b and 11b, and that the rollers 10c and 11c and the shafts 10b and 11b are arranged to be away from the detection area in a vertical D3 view, and that the first guide section 10 further includes a projection 10e extending from the shaft 10b so as to overlap with the detection area in a vertical D3 view.

[0097] With this configuration, since the protrusion 10e of the first guide portion 10 extends in the second lateral direction D2 from the axis 10b toward the reinforcing inner surface 3e, the protrusion 10e of the first guide portion 10 overlaps with the detection area of ​​the detection unit 1b when viewed in the vertical direction D3. As a result, only the first guide portion 10 can be detected by the detection unit 1b.

[0098] It should be noted that the parking device 1 and the gate device 1a for the parking device are not limited to the configuration of the embodiment described above, nor are they limited to the effects described above. Furthermore, it goes without saying that the parking device 1 and the gate device 1a for the parking device can be modified in various ways without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations and methods, etc., related to the various modification examples described below may be arbitrarily selected and adopted in the configurations and methods, etc., of the embodiment described above.

[0099] (1) In the parking gate device 1a according to the above embodiment, the first and second detection units 1b and 1c are fixed to the same first support column 3 and detect the position of the same first guide unit 10. However, the parking gate device 1a is not limited to this configuration.

[0100] For example, the first and second detection units 1b and 1c may be configured to detect the positions of different guide units 6b, 10, and 11 among a plurality of guide units 6b, 10, and 11. Alternatively, for example, at least one of the first and second detection units 1b and 1c may be configured to detect the positions of the gate bodies 5a and 6a (e.g., the position of the upper end, the position of the lower end, etc.).

[0101] Furthermore, for example, one of the first and second detection units 1b, 1c may be fixed to the first support column 3, and the other may be fixed to the second support column 4. Also, the gate device 1a may not have both the first and second detection units 1b, 1c, but may have only the first detection unit 1b, or it may have only the second detection unit 1c.

[0102] (2) In addition, in the parking gate device 1a according to the above embodiment, the guide sections 10 and 11 are configured to include rollers 10c and 11c that can rotate around axes 10b and 11b. However, the parking gate device 1a is not limited to this configuration. For example, the guide sections 10 and 11 may be configured to include sliding members that slide on rails 8.

[0103] (3) In addition, in the parking gate device 1a according to the above embodiment, the rollers 10c and 11c are provided with grooves 10d and 11d that extend over the entire circumference of their outer periphery, and the regulating portion 8a is arranged inside the grooves 10d and 11d. However, the parking gate device 1a is not limited to this configuration. For example, the regulating portion 8a may be provided with a pair of clamping portions that clamp the rollers 10c and 11c in the second lateral direction D2.

[0104] (4) In addition, in the parking gate device 1a according to the above embodiment, the second detector 14b of the second sensor 14 extends from the second sensor body 14a so as to overlap with the regulating section 8a in the first lateral view D1. However, the parking gate device 1a is not limited to this configuration. For example, the second detector 14b of the second sensor 14 may be configured to extend from the second sensor body 14a so as to move away from the regulating section 8a in the first lateral view D1.

[0105] (5) In addition, in the parking gate device 1a according to the above embodiment, the first and second sensors 12 and 14 are contact sensors having detectors 12b and 14b. However, the parking gate device 1a is not limited to this configuration. For example, at least one of the first and second sensors 12 and 14 may be, for example, a proximity sensor, or a photoelectric sensor.

[0106] (6) Furthermore, in the parking gate device 1a according to the above embodiment, the rollers 10c and 11c of the first and second guide sections 10 and 11 are separated from the detection area in the vertical direction D3 view, and the protruding portion 10e of the first guide section 10 overlaps with the detection area in the vertical direction D3 view. However, the parking gate device 1a is not limited to this configuration.

[0107] For example, the thickness of the roller 10c of the first guide section 10 (dimension in the second lateral direction D2) may be greater than the thickness of the roller 11c of the second guide section 11, so that the roller 10c of the first guide section 10 overlaps with the detection area in the vertical direction D3 view, while the roller 11c of the second guide section 11 is separated from the detection area in the vertical direction D3 view.

[0108] (7) In addition, in the parking gate device 1a according to the above embodiment, the gates 5 and 6 are arranged such that their ends overlap with the reinforcing inner surfaces 3b and 3f in a second lateral view D2. However, the parking gate device 1a is not limited to this configuration. The gates 5 and 6 may also be arranged so as to be away from the reinforcing inner surfaces 3b and 3f in a second lateral view D2.

[0109] (8) In addition, in the parking gate device 1a according to the above embodiment, the first and second sensors 12 and 14 are fixed to the support column 3 via brackets 13a and 15a. However, the parking gate device 1a is not limited to this configuration. For example, the first and second sensors 12 and 14 may be fixed in contact with the support column 3.

[0110] (9) In addition, in the parking gate device 1a according to the above embodiment, the first and second sensors 12 and 14 are arranged such that a portion of them overlaps with the reinforcing inner surface 3b in the second lateral view D2. However, the parking gate device 1a is not limited to this configuration.

[0111] For example, at least one of the first and second sensors 12, 14 may be arranged such that it completely overlaps with the reinforced inner surface 3b in the second lateral view D2. For example, at least one of the first and second sensors 12, 14 may be arranged so that it is away from the reinforced inner surface 3b in the second lateral view D2.

[0112] (9) In addition, in the parking gate device 1a according to the above embodiment, the first and second detection units 1b and 1c are fixed to the first reinforcing inner surface 3e. However, the parking gate device 1a is not limited to this configuration.

[0113] For example, as shown in Figures 12 and 13, at least one of the first and second detection units 1b, 1c (both of the first and second detection units 1b, 1c in Figures 12 and 13) may be fixed to, for example, the inner surface 3d of the base. Alternatively, at least one of the first and second detection units 1b, 1c may be fixed to the second reinforcing inner surface 3f.

[0114] Alternatively, for example, at least one of the first and second detection units 1b, 1c may be fixed to the surface of the base unit 3a opposite to the inner surface 3d of the base. Alternatively, for example, at least one of the first and second detection units 1b, 1c may be fixed to the surface of the first and second reinforcing units 3b, 3c opposite to the reinforcing inner surfaces 3e, 3f of the base. Alternatively, for example, at least one of the first and second detection units 1b, 1c may be fixed to the third and fourth reinforcing units 3g, 3h.

[0115] (10) In addition, in the parking gate device 1a according to the above embodiment, the first and second sensors 12 and 14 are configured such that a portion of them are positioned between the reinforcing inner surface 3e and the gates 5 and 6 (specifically, the first guide portion 10) in a vertical view D3. However, the parking gate device 1a is not limited to this configuration.

[0116] For example, at least one of the first and second sensors 12, 14 may be configured to be entirely positioned between the reinforced inner surface 3e and the gates 5, 6 in a vertical D3 view. Alternatively, as shown in Figures 12 and 13, at least one of the first and second sensors 12, 14 (both of the first and second sensors 12, 14 in Figures 12 and 13) may be positioned outside the space between the reinforced inner surface 3e and the gates 5, 6 in a vertical D3 view.

[0117] (12) In addition, in the parking gate device 1a according to the above embodiment, the axes 10b and 11b of the guide sections 10 and 11 extend in the second lateral direction D2. However, the parking gate device 1a is not limited to this configuration. For example, as shown in Figures 12 and 13, the axes 10b and 11b of the guide sections 10 and 11 may extend in the first lateral direction D1.

[0118] (12-1) In addition, as shown in Figures 12 and 13, in a configuration in which the axes 10b and 11b of the guide sections 10 and 11 extend in the first lateral direction D1, the rail 8 may be provided with a restricting section 8a that strikes the guide sections 10 and 11 in the first lateral direction (a predetermined lateral direction) D1 in order to restrict the movement of the guide sections 10 and 11 in the first lateral direction (a predetermined lateral direction) D1.

[0119] (12-2) Alternatively, as shown in Figure 12, in a configuration where the axes 10b and 11b of the guide sections 10 and 11 extend in the first lateral direction D1, the regions in which the first and second guide sections 10 and 11 move in the vertical direction D3 each include a position that overlaps with the detection area in the first lateral direction (a predetermined lateral direction) D1 view, the first guide section 10 is positioned so as to overlap with the detection area of ​​the first detection section 1b in the vertical direction D3 view, and although not shown, the second guide section 11 is positioned so as to move away from the detection area of ​​the first detection section 1b in the vertical direction D3 view.

[0120] (12-3) Alternatively, as shown in Figure 12, in a configuration where the axes 10b and 11b of the guide sections 10 and 11 extend in the first lateral direction D1, the first guide section 10 may be provided with a projection 10e that extends from the axis 10b in the first lateral direction (a predetermined lateral direction) D1 so as to overlap with the detection area of ​​the first detection section 1b when viewed in the vertical direction D3.

[0121] (12-4) Alternatively, as shown in Figure 13, in a configuration where the axes 10b and 11b of the guide sections 10 and 11 extend in the first lateral direction D1, the restricting section 8a may be positioned inside the grooves 10d and 11d so as to strike the rollers 10c and 11c in the first lateral direction (a predetermined lateral direction) D1, the second sensor body 14a may be separated from the restricting section 8a in the view of the second lateral direction (orthogonal lateral direction) D2, and the second detector 14b may extend from the second sensor body 14a so as to overlap with the restricting section 8a in the view of the second lateral direction (orthogonal lateral direction) D2.

[0122] (13) In addition, in the parking gate device 1a according to the above embodiment, the first sensor 12 detects the first guide portion 10 while not detecting the second guide portion 11, with respect to the first and second guide portions 10 and 11 which are guided by a common rail 8. However, the parking gate device 1a is not limited to this configuration.

[0123] For example, the rail 8 fixed to the first support column 3 may be configured to include first and second rails 8, 8 arranged in the second lateral direction D2, with the first guide section 10 being guided by the first rail 8 and the second guide section 11 being guided by the second rail 8. In such a configuration, the first sensor 12 may detect the first guide section 10 but not the second guide section 11.

[0124] (14) In addition, in the parking device 1 according to the above embodiment, the second lateral direction D2 is the direction in which the vehicle X1 enters and exits the pallet 2, that is, the front-to-back direction of the vehicle X1. However, the parking device 1 is not limited to this configuration. For example, the parking device 1 may be configured such that the vehicle X1 passes through the gate device 1a with the vehicle X1 placed on the pallet 2, and the second lateral direction D2 is the left-to-right direction of the vehicle X1.
