Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, the problem is to provide a gate device for a parking apparatus and a parking apparatus in which a winding device can be arranged below the upper end portion of a column.

Means for Solving the Problems

[0005] A gate device for a parking apparatus includes a column extending in the vertical direction, a gate arranged along the vertical direction and the first horizontal direction and movable in the vertical direction, a rope connected to the gate, an upper sheave attached to the upper end portion of the column and wound around the rope, and a winding device attached to the column and configured to wind the rope from a first end portion, wherein the winding device is arranged below the upper sheave.

[0006] The parking system includes the aforementioned gate device for the parking system. [Brief explanation of the drawing]

[Figure 2] Overall front view showing the open state of the gate device for the parking system. [Figure 3] Enlarged view of the main part in Figure 2 [Figure 4] Side view of Figure 3 [Figure 5] Plan view in Figure 3 [Modes for carrying out the invention]

[0008] The following describes one embodiment of a parking system and a gate system for a parking system, with reference to Figures 1 to 5. Note that 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] The parking device 1 is installed on a fixed structure X2. Although not particularly limited, in this embodiment, the fixed structure X2 has a pit X4 that is recessed downward from a reference position (e.g., the ground) X3, and the pallet 2 can move not only to a position above the reference position X3 but also to a position below it. Alternatively, the fixed structure X2 may not have the pit X4, and the pallet 2 may only be able to move to a position above the reference position X3.

[0011] For example, multiple pallets 2 may be arranged in the vertical direction D3 (two in Figures 1 and 2). Alternatively, multiple pallets 2 may be arranged in the first horizontal direction D1, or in the second horizontal direction D2. By moving the pallets 2, for example, a desired vehicle X1 can be removed from the pallet 2 or a vehicle X1 can be moved into a desired pallet 2.

[0012] In this embodiment, the second lateral direction D2 is the direction in which the vehicle X1 enters and exits the pallet 2, and the first lateral direction D1 is the lateral direction perpendicular to the second lateral direction D2. Hereafter, 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 called the left-right direction, and the second lateral direction D2 is also called the front-rear direction.

[0013] Furthermore, in each figure, the direction of the arrow in the first horizontal direction D1 is also called the left direction, and the direction opposite to the arrow in the first horizontal direction D1 is also called the right direction. Also, in each figure, the direction of the arrow in the second horizontal direction D2 is also called the forward direction, and the direction opposite to the arrow in the second horizontal direction D2 is also called the backward direction.

[0014] The gate device 1a may, for example, include a pair of support columns 3 and 4 extending in the vertical direction D3, gates 5 and 6 positioned between a pair of support columns 3 and 4 separated in the first horizontal direction D1, a lifting device 7 for moving gates 5 and 6 in the vertical direction D3 relative to the support columns 3 and 4, rails 8 for guiding gates 5 and 6 in the vertical direction D3, and a support part 9 for supporting gate 5 from below.

[0015] Gates 5 and 6 may be arranged along the first lateral direction D1 and the vertical direction D3, for example, as in this embodiment. Also, while gates 5 and 6 are not particularly limited, in this embodiment there are two. Specifically, gates 5 and 6 consist of a first gate (also called the "lower gate") 5 and a second gate (also called the "upper gate") 6 positioned above the first gate 5. Note that there may be only one gate 5 or 6, or there may be three or more gates.

[0016] The lifting device 7 may, for example, as in this embodiment, include a rope (e.g., wire, chain, etc.) 10 connected to the second gate 6, an upper sheave 11 wrapped around the rope 10 and rotatably attached to the upper end of the first support column 3, a lower sheave 12 wrapped around the rope 10 and rotatably attached to the first support column 3 at a position lower than the upper sheave 11, and a winding device 13 attached to the first support column 3 that moves the gates 5 and 6 in the vertical direction D3 by winding up the rope 10 from the first end.

[0017] The lifting device 7 may, for example, include a rope fixing part 7a for fixing the second end of the rope 10 to the second support column 4, and gate sheaves 7b, 7b that are wrapped around the rope 10 and rotatably connected to the second gate 6, as in this embodiment. In this way, the second gate 6 is connected to the rope 10 via the gate sheaves 7b, 7b. Alternatively, the second gate 6 may be connected to the rope 10 by fixing the second end of the rope 10 to the second gate 6.

[0018] Then, as the winding device 13 winds up the rope 10, the second gate 6 rises, and for example, the lower end of the second gate 6 engages with the upper end of the first gate 5, causing the first gate 5 to rise together with the second gate 6. As a result, as shown in Figure 1, the 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.

[0019] Further, when the take-up device 13 pays out the rope 10, the second gate 6 descends. For example, since the upper end of the first gate 5 is engaged with the lower end of the second gate 6, the first gate 5 also descends together with the second gate 6. Thereafter, when the first gate 5 is supported from below by the support portion 9, only the second gate 6 descends. As a result, as shown in FIG. 2, since the gates 5 and 6 are located at the open positions, the gate device 1a is in an open state in which the vehicle X1 can enter and exit.

[0020] Thus, in the present embodiment, the gate device 1a is in an open state when the gates 5 and 6 descend below the reference position X3, and the gate device 1a is in a closed state when the gates 5 and 6 rise above the reference position X3. Note that, for example, a configuration may be adopted in which the gate device 1a is in an open state when the gates 5 and 6 rise, and the gate device 1a is in a closed state when the gates 5 and 6 descend.

[0021] The take-up device 13 may be disposed, for example, below the upper sheave 11 as in the present embodiment. Thereby, the take-up device 13 can be disposed below the upper end portion of the first support column 3. Therefore, for example, the work of installing and maintaining the take-up device 13 can be facilitated. Although not particularly limited, the distance at which the take-up device 13 is separated from the reference position X3 may be, for example, within 1.5 m, or may be, for example, within 1.0 m.

[0022] Further, the lower sheave 12 may be disposed, for example, below the take-up device 13 as in the present embodiment. The rope 10 may be wound, for example, in the order of the take-up device 13, the lower sheave 12, the upper sheave 11, and the gate sheave 7b from the first end as in the present embodiment. Thereby, the rope 10 includes a first rope portion 10a which is a portion between the take-up device 13 and the lower sheave 12, and a second rope portion 10b which is a portion between the lower sheave 12 and the upper sheave 11.

[0023] While not particularly limited, as in this embodiment, for example, the upper sheave 11 may rotate around a rotation axis 11a extending in the second lateral direction D2, and the lower sheave 12 may rotate around a rotation axis 12a extending in the first lateral direction D1 (see also Figure 3). That is, for example, in a view in the vertical direction D3, the rotation axis 11a of the upper sheave 11 may be orthogonal to the rotation axis 12a of the lower sheave 12 (including not only perfectly orthogonal at 90°, but also approximately orthogonal at 90° ± 5°).

[0024] As shown in Figure 3, the lower sheave 12 may, for example, be provided with a sheave groove 12b extending along its entire length on its outer circumference so as to contact the rope 10 from both sides in the axial direction D1 of the lower sheave 12 (hereinafter also referred to as the "lower sheave axial direction"), as in this embodiment. This restricts the movement of the rope 10 relative to the lower sheave 12 in the lower sheave axial direction D1, thereby preventing the rope 10 from coming off the lower sheave 12.

[0025] As shown in Figures 3 to 5, the winding device 13 may, for example, include a rotatable drum 14 around which the rope 10 is wound, a drive source (e.g., a motor) 15 that rotates the drum 14 around its rotation axis 14a, and a transmission unit 16 (e.g., a reduction gear, a speed changer) that transmits the drive of the drive source 15 to the drum 14. Although not particularly limited, for example, as in this embodiment, the winding device 13 may be attached to the first support column 3 by fixing the drive source 15 to a fixing device 17 (shown only in Figure 5).

[0026] The drum 14 may, for example, have a guide groove 14b on its outer circumference around which the rope 10 is wound, as in this embodiment. The guide groove 14b may, for example, extend spirally around the rotation axis 14a of the drum 14, as in this embodiment. As a result, the rope 10 is guided by the guide groove 14b and wound onto the outer circumference of the drum 14 while shifting its position in the axial direction of the drum 14 (hereinafter also referred to as the "drum axis direction") D2.

[0027] Therefore, as the winding device 13 winds (or unwinds) the rope 10, the position of the first end 10c of the first rope section 10a on the winding device 13 side is displaced in the drum axis direction D2. On the other hand, since the position of the second end 10d of the first rope section 10a on the lower sheave 12 side remains constant, the first rope section 10a swings in the drum axis direction D2 with the lower sheave 12 as the pivot point.

[0028] This prevents the portion 10b of the rope 10 between the upper sheave 11 and the lower sheave 12, i.e., the second rope portion 10b, from swaying when the winding device 13 winds up the rope 10. As a result, for example, it is possible to prevent the rope 10 from coming off the upper sheave 11.

[0029] While not particularly limited, in this embodiment, the first rope section 10a swings in the drum axis direction D2 from the position of the solid line in Figure 4 to the position of the dashed line. In Figure 5, the solid line with the inside filled in of the first end 10c of the first rope section 10a indicates the position of the solid line in the rope 10 in Figure 4, and the dashed line of the first end 10c of the first rope section 10a indicates the position of the dashed line in the rope 10 in Figure 4.

[0030] Furthermore, as shown in Figures 1 and 2, the vertical distance D3 between the winding device 13 and the lower sheave 12 may be smaller than the vertical distance D3 between the winding device 13 and the upper sheave 11, for example, as in this embodiment. Specifically, the vertical distance D3 between the drum 14 and the lower sheave 12 may be smaller than the vertical distance D3 between the drum 14 and the upper sheave 11, for example, as in this embodiment.

[0031] This makes it possible to reduce the vertical distance D3 of the swinging portion of the rope 10, i.e., the first rope portion 10a. Therefore, the area in the vertical direction D3 where the swinging portion, the first rope portion 10a, is located can be reduced.

[0032] By the way, as shown in Figures 3 to 5, although the lower sheave 12 is equipped with a sheave groove 12b, the rope 10 is more likely to come off the lower sheave 12 when the first rope portion 10a swings in the direction D1 of the lower sheave axis than when the first rope portion 10a swings in the direction D2 perpendicular to the lower sheave axis D1. Therefore, the rotation axis 14a of the drum 14 may be perpendicular to the rotation axis 12a of the lower sheave 12 in a view in the vertical direction D3, for example, as in this embodiment (including not only perfectly perpendicular at 90°, but also approximately perpendicular at 90° ± 5°).

[0033] As a result, the first rope section 10a swings in a direction D2 perpendicular to the lower sheave axis direction D1, that is, the first rope section 10a swings in the view of the lower sheave axis direction D1, thereby preventing the rope 10 from coming off the lower sheave 12. Although not particularly limited, in this embodiment, the drum axis direction D2 is the second lateral direction D2, and the lower sheave axis direction D1 is the first lateral direction D1.

[0034] Alternatively, for example, as in this embodiment, the drum 14 may be configured such that it has a winding region 14c on which the rope 10 can be wound, and the end 12c of the lower sheave 12 in the drum axis direction D2 is located in the central region 14d of the winding region 14c. In this configuration, the second end 10d of the first rope portion 10a is located in the central region 14d of the winding region 14c in the drum axis direction D2.

[0035] Therefore, the swing angle θ1 of the first rope section 10a with the lower sheave 12 as the base point can be reduced, which further suppresses, for example, the rope 10 from coming off the lower sheave 12. The central region 14d may be, for example, the two central regions 14d, 14d of the region obtained by dividing the winding region 14c into four equal parts along the drum axis direction D2. The regions 14e, 14e on both sides of the two central regions 14d, 14d are called the end regions 14e, 14e of the winding region 14c.

[0036] Thus, the position of the drum 14 relative to the lower sheave 12 may be set such that the swing angle θ1 of the first rope section 10a is small. Although not particularly limited, the position of the drum 14 relative to the lower sheave 12 may be set such that the swing angle θ1 of the first rope section 10a is 30° or less.

[0037] Furthermore, as shown in Figures 2 to 4, the first rope section 10a may be located inside the pit X4, for example, as in this embodiment. Specifically, the winding device 13 and the lower sheave 12 may be located inside the pit X4, for example, as in this embodiment. As a result, the first rope section 10a, which is the part of the rope 10 that swings, is located below the reference position X3, so that the rope 10 does not come into contact with a person, for example, when a person is walking above the reference position X3.

[0038] Furthermore, since the first rope section 10a is located inside the pit X4, the lower sheave 12 may be positioned lower than the lowest position where the lower ends of the gates 5 and 6 are located, as in this embodiment. This increases the distance between the lower sheave 12 and the winding device 13, thereby increasing the length of the first rope section 10a. Consequently, the swing angle θ1 of the first rope section 10a with the lower sheave 12 as the base point can be reduced, further suppressing, for example, the rope 10 from coming off the lower sheave 12.

[0039] While not particularly limited, for example, as in this embodiment, the first rope section 10a may be inclined with respect to the vertical direction D3 so as to move away from the first support column 3 from the second end 10d to the first end 10c. This increases the amplitude of the swing of the first end 10c of the first rope section 10a, but because the first end 10c of the first rope section 10a is away from the first support column 3 in the first lateral direction D1, contact between the rope 10 and the first support column 3 can be suppressed.

[0040] Furthermore, as shown in Figures 3 and 4, the winding device 13 may be arranged such that, for example, in this embodiment, a portion of it overlaps with the first support column 3 in a second lateral view D2. This reduces the amount by which the winding device 13 protrudes from the first support column 3 in a second lateral view D2, thereby reducing the dimension of the gate device 1a in the first lateral direction D1.

[0041] Furthermore, the dimension W1 of the winding device 13 in the first lateral direction D1 may be smaller than the dimension W2 of the winding device 13 in the second lateral direction D2, as in this embodiment. This prevents the dimension of the gate device 1a in the first lateral direction D1 from becoming larger. Therefore, for example, it is possible to prevent the dimension of the pit X4 in the first lateral direction D1 from becoming larger.

[0042] For example, the drum 14 and the transmission unit 16 may be arranged so as to be aligned in the second horizontal direction D2, specifically so as to overlap in the second horizontal direction D2 view, as in this embodiment. Also, for example, the drive source 15 and the transmission unit 16 may be arranged so as to be aligned in the vertical direction D3, specifically so as to overlap in the vertical direction D3 view, as in this embodiment.

[0043] Based on the above, as in this embodiment, the parking device 1 is equipped with the aforementioned parking device gate device 1a.

[0044] 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, a rope 10 connected to the gate (in this embodiment, the second gate) 6, an upper sheave 11 attached to the upper end of the support column 3 and wound around the rope 10, and a winding device 13 attached to the support column 3 and winding the rope 10 from the first end, wherein the winding device 13 is positioned below the upper sheave 11.

[0045] With this configuration, the rope 10 is wrapped around the upper sheave 11 and wound onto the winding device 13 from the first end, allowing the gates 5 and 6 to move vertically in the direction D3. The upper sheave 11 is attached to the upper end of the support column 3, and the winding device 13 is attached to the support column 3 below the upper sheave 11. This allows the winding device 13 to be positioned below the upper end of the support column 3.

[0046] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable to further include a lower sheave 12 attached to the support column 3 at a position lower than the winding device 13, and to have the rope 10 wound in the order of the winding device 13, the lower sheave 12, and the upper sheave 11 from the first end.

[0047] With this configuration, when the winding device 13 winds up the rope 10, it is possible to suppress the movement of the portion 10b of the rope 10 between the upper sheave 11 and the lower sheave 12. This prevents, for example, the rope 10 from coming off the upper sheave 11.

[0048] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the portion 10a of the rope 10 between the winding device 13 and the lower sheave 12 is located inside a pit X4 that is recessed downward from the reference position X3.

[0049] With this configuration, when the winding device 13 winds up the rope 10, the portion 10a of the rope 10 between the winding device 13 and the lower sheave 12 will swing. However, since this portion 10a of the rope 10 is located inside the pit X4, the swinging portion 10a of the rope 10 is located below the reference position X3.

[0050] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the lower sheave 12 is positioned below the lowest position where the lower ends of the gates 5 and 6 are located.

[0051] With this configuration, since the lower sheave 12 is positioned below the lowest position of the lower end of the gates 5 and 6, the length of the portion 10a of the rope 10 between the winding device 13 and the lower sheave 12 can be increased. This makes it possible to reduce the swing angle θ1 of the rope 10 with the lower sheave 12 as the pivot point.

[0052] Furthermore, in this embodiment, the parking gate device 1a is preferably further equipped with a lower sheave 12 attached to the support column 3 at a position lower than the winding device 13, the winding device 13 is equipped with a rotatable drum 14 on which the rope 10 is wound, and the rotation axis 14a of the drum 14 is perpendicular to the rotation axis 12a of the lower sheave 12 when viewed in the vertical direction D3.

[0053] With this configuration, the rotation axis 14a of the drum 14 is perpendicular to the rotation axis 12a of the lower sheave 12 in a vertical direction D3 view, so the rope 10 will swing in a direction D2 perpendicular to the axial direction D1 of the lower sheave 12 (in a view of the axial direction D1 of the lower sheave 12). This makes it possible to prevent the rope 10 from coming off the lower sheave 12, for example.

[0054] Furthermore, in the parking gate device 1a as in this embodiment, it is preferable that the winding device 13 is arranged such that at least a portion of it overlaps with the support column 3 when viewed in a second lateral direction D2 perpendicular to the first lateral direction D1, and that the dimension W1 of the winding device 13 in the first lateral direction D1 is smaller than the dimension W2 of the winding device 13 in the second lateral direction D2.

[0055] With this configuration, at least a portion of the winding device 13 overlaps with the support column 3 in the second lateral direction D2 view, and the dimension W1 of the winding device 13 in the first lateral direction D1 is smaller than the dimension W2 of the winding device 13 in the second lateral direction D2, thereby preventing the dimension of the gate device 1a in the first lateral direction D1 from becoming larger.

[0056] 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.

[0057] (1) In the parking gate device 1a according to the above embodiment, the winding device 13, the first rope section 10a, and the lower sheave 12 are arranged inside the pit X4. However, the parking gate device 1a is not limited to this configuration.

[0058] For example, a part of the winding device 13 may be positioned above the reference position X3, and the first rope section 10a and the lower sheave 12 may be positioned inside the pit X4, which is below the reference position X3. Alternatively, for example, at least a part of the winding device 13 and the first rope section 10a may be positioned above the reference position X3. Alternatively, for example, the lower sheave 12 may be positioned above the reference position X3.

[0059] (2) In the parking gate device 1a according to the above embodiment, the rope 10 is wound in the order of winding device 13, lower sheave 12, and upper sheave 11 from the first end. However, the parking gate device 1a is not limited to this configuration. For example, the lower sheave 12 may not be provided, and the rope 10 may be wound in the order of winding device 13 and upper sheave 11 from the first end.

[0060] (3) In addition, in the parking gate device 1a according to the above embodiment, the lower sheave 12 is positioned below the lowest position where the lower ends of the gates 5 and 6 are located. However, the parking gate device 1a is not limited to this configuration. For example, the lower sheave 12 may be positioned above the lowest position of the gates 5 and 6.

[0061] (4) In addition, in the parking gate device 1a according to the above embodiment, the rotation axis 14a of the drum 14 is perpendicular to the rotation axis 12a of the lower sheave 12 when viewed in the vertical direction D3. However, the parking gate device 1a is not limited to this configuration.

[0062] For example, the rotation axis 14a of the drum 14 may be parallel to the rotation axis 12a of the lower sheave 12 in a vertical D3 view. Alternatively, for example, the rotation axis 14a of the drum 14 may be inclined with respect to the rotation axis 12a of the lower sheave 12 in a vertical D3 view.

[0063] (5) In addition, in the parking gate device 1a according to the above embodiment, a part of the winding device 13 is configured to overlap with the support column 3 in the second lateral view D2. However, the parking gate device 1a is not limited to this configuration. For example, the entire winding device 13 may be configured to overlap with the support column 3 in the second lateral view D2. Alternatively, for example, the winding device 13 may be configured to be separated from the support column 3 in the second lateral view D2.

[0064] (6) In addition, in the parking gate device 1a according to the above embodiment, the dimension W1 of the winding device 13 in the first lateral direction D1 is smaller than the dimension W2 of the winding device 13 in the second lateral direction D2. However, the parking gate device 1a is not limited to this configuration.

[0065] For example, the dimension W1 of the winding device 13 in the first lateral direction D1 may be larger than the dimension W2 of the winding device 13 in the second lateral direction D2. Alternatively, for example, the dimension W1 of the winding device 13 in the first lateral direction D1 may be the same as the dimension W2 of the winding device 13 in the second lateral direction D2.

[0066] (7) In addition, in the parking gate device 1a according to the above embodiment, the vertical distance D3 between the winding device 13 and the lower sheave 12 is smaller than the vertical distance D3 between the winding device 13 and the upper sheave 11. However, the parking gate device 1a is not limited to this configuration.

[0067] For example, the vertical distance D3 between the winding device 13 and the lower sheave 12 may be greater than the vertical distance D3 between the winding device 13 and the upper sheave 11. Alternatively, for example, the vertical distance D3 between the winding device 13 and the lower sheave 12 may be the same as the vertical distance D3 between the winding device 13 and the upper sheave 11.

[0068] (8) In addition, in the parking gate device 1a according to the above embodiment, the winding device 13 is configured to include a drive source 15 for rotating the drum 14. However, the parking gate device 1a is not limited to this configuration. For example, the winding device 13 may be configured to rotate the drum 14 manually (by human power). In such a configuration, the winding device 13 may include, for example, a handle that is gripped when rotating the drum 14.

[0069] (9) 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.
