Description

[Technical Field]

[0001] The present invention relates to a gate device for a parking system and a parking system. [Background technology]

[0002] A typical parking device is equipped with a gate device for closing the entrance and exit of a vehicle, preventing people from entering the parking device when a pallet for transporting a vehicle is being moved. The gate device has a gate that rises and falls between a pair of support posts.

[0003] Incidentally, as described in Patent Document 1, it is conceivable to divide the gate into upper and lower halves and arrange the two divided gates one behind the other to raise and lower the gate, thereby increasing the height when closed and decreasing the height when stored. However, with the structure described in Patent Document 1, the upper and lower divided gates are raised and lowered independently by separate chains, making it difficult to raise and lower the upper and lower gates in a stable position approximately parallel to each other.

[0009] Hereinafter, one embodiment of a parking device and a gate device for a parking device will be described with reference to Figures 1 to 9. Note that in each figure, the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either.

[0010] As shown in Figures 1 and 2, the parking device 1 may, for example, as in this embodiment, be equipped with a pallet 2 on which the vehicle X1 is placed, a pallet drive device (not shown) that moves the pallet 2, and a parking device gate device (hereinafter simply referred to as "gate device") 3 that separates a storage space in which the vehicle X1 placed on the pallet 2 is stored from an external space outside the storage space.

[0011] 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 recessed downward relative to a reference position (e.g., the ground) X3, and the pallet 2 can be moved not only above but also below the reference position X3. Alternatively, the fixed structure X2 may not have the pit X4, and the pallet 2 may be moved only to a position above the reference position X3.

[0012] For example, a plurality of pallets 2 (two in FIGS. 1 and 2) may be arranged in the vertical direction D3. Note that a plurality of pallets 2 may be arranged in the first horizontal direction D1, or a plurality of pallets 2 may be arranged in the second horizontal direction D2. For example, by moving the pallets 2, a desired vehicle X1 can exit from the pallet 2 or enter into the desired pallet 2.

[0013] The second lateral direction D2 is the direction in which the vehicle X1 moves in and out of the pallet 2, and the first lateral direction D1 is a lateral direction perpendicular to the second lateral direction D2. Hereinafter, the lateral directions D1 and D2 may be defined based on the vehicle X1. For example, the first lateral direction D1 may also be referred to as the left-right direction, and the second lateral direction D2 may also be referred to as the front-rear direction.

[0014] In each drawing, the arrow direction of the first horizontal direction D1 is also referred to as the left direction, and the opposite direction of the arrow direction of the first horizontal direction D1 is also referred to as the right direction. In each drawing, the arrow direction of the second horizontal direction D2 is also referred to as the forward direction, and the opposite direction of the arrow direction of the second horizontal direction D2 is also referred to as the backward direction.

[0015] For example, as in this embodiment, the gate device 3 includes a pair of support pillars 4a, 4b spaced apart in the first horizontal direction D1, gates 5, 6 disposed between the pair of support pillars 4a, 4b, and a lifting device 7 that moves the gates 5, 6 in the up-down direction D3 relative to the support pillars 4a, 4b. Furthermore, the gate device 3 may include support pillar guide rails 42 (described later) that guide the gates 5, 6 in the up-down direction D3, and a support part 9 that supports the gate 5 from below.

[0016] Although there is no particular limitation on the number of gates 5 and 6, in this embodiment, two are provided. Specifically, the 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.

[0017] The lifting device 7 may, for example, as in this embodiment, include a rope 7a made of a wire, chain, or the like, a rope fixing portion 7b that fixes the first end of the rope 7a to the first support pillar 4a, gate sheaves 7c and 7d that are wound around the rope 7a and rotatably connected to the second gate 6, support pillar sheaves 7e and 7f that are wound around the rope 7a and rotatably connected to the second support pillar 4b, and a drive device 7g that drives the second end side of the rope 7a to move the gates 5 and 6.

[0018] Although not particularly limited, in this embodiment, the driving device 7g is a winding device that winds up the second end of the rope 7a. Note that the lifting device 7 may include, for example, a weight fixed to the second end of the rope 7a, and the driving device 7g may be a motor that applies rotational drive to the support sheave 7e.

[0019] Then, the second gate 6 is raised by the lifting device 7, and the upper end of the first gate 5 engages with the lower end of the second gate 6, causing the first gate 5 to rise together with the second gate 6. As a result, as shown in FIG. 1, the gates 5 and 6 are positioned in the closed position, and the gate device 3 is in a closed state in which it is not possible for the vehicle X1 to enter or exit.

[0020] Furthermore, the second gate 6 is lowered by the lifting device 7, and the upper end of the first gate 5 engages with the lower end of the second gate 6, causing the first gate 5 to also lower together with the second gate 6, and then, as shown in Fig. 2, the first gate 5 is supported from below by the support part 9. As a result, the gates 5 and 6 are in the open position, and the gate device 3 is in an open state in which the vehicle X1 can be let in and out.

[0021] As described above, in this embodiment, the gate device 3 is opened when the gates 5 and 6 are lowered below the reference position X3, and closed when the gates 5 and 6 are raised. Note that, for example, the fixed structure X2 may not have the pit X4, and the gates 5 and 6 may be movable only to positions above the reference position X3, and the gate device 3 may be opened when the gates 5 and 6 are raised, and closed when the gates 5 and 6 are lowered.

[0022] The pillars 4a and 4b may extend in the vertical direction D3, for example, from a position above the reference position X3 to a position below the reference position X3. The pillar guide rail 42 may extend in the vertical direction D3, for example, from a position above the reference position X3 to a position below the reference position X3, and may be fixed to the pillars 4a and 4b.

[0023] The pair of support columns 4a, 4b includes a first support column 4a on the left side and a second support column 4b on the right side. Since the first support column 4a and the second support column 4b have substantially symmetrical shapes, the following description will mainly focus on the first support column 4a.

[0024] The first support pillar 4a is fixed to the front wall surface X4a of the pit X4 (see FIG. 8). The first support pillar 4a has an H-shaped cross section. That is, the first support pillar 4a has a pair of flanges 41, 42 extending toward the second support pillar 4b. The pair of flanges 41, 42 are spaced apart in the front-rear direction D2, and thus the first support pillar 4a has a recess 43 extending in the up-down direction D3 and opening toward the gates 5, 6. The first support pillar 4a may have a C-shaped (or U-shaped) cross section and may have the recess 43. Furthermore, although the first support pillar 4a of this embodiment is configured to have the recess 43 opening toward the gates 5, 6, it is not necessarily required to have the recess 43. For example, the first support pillar 4a and the second support pillar 4b may be formed from square pipes.

[0025] The front flange 41 is fixed to the front wall surface X4a of the pit X4 with screws or the like. The rear flange 42 functions as a support guide rail 42 (an example of a second guide rail) that guides gate rollers 5c and 6c, which will be described later. Note that in this embodiment, the flange 42 is used as the support guide rail, but a separate support guide rail may also be fixed to the supports 4a and 4b.

[0026] The first gate 5 comprises a first gate main body 5a, a gate guide rail 5b (an example of a first guide rail) fixed to the first gate main body 5a, a gate roller 5c (an example of a second guide portion) fixed to the first gate main body 5a, and a first stopper portion 5d fixed to the first gate main body 5a.

[0027] The first gate body 5a includes a first gate panel 50 and a first gate frame 51 that surrounds the first gate panel 50. The first gate panel 50 is formed from a thin plate-like member, and has a large number of through holes formed in a portion thereof.

[0028] The first gate frame 51 comprises a pair of first horizontal frames 52, 53 whose length in the left-right direction D1 is approximately the same as the length between the first support pillar 4a and the second support pillar 4b, and a pair of first vertical frames 54, 54 connecting both ends of the pair of first horizontal frames 52, 53 in the left-right direction D1.

[0029] The pair of first horizontal frames 52, 53 are spaced apart in the vertical direction D3. The first gate panel 50 and the pair of first vertical frames 54, 54 are fixed to the front sides of the pair of first horizontal frames 52, 53.

[0030] 4, the upper first horizontal frame 52 is a plate-like member bent so that its cross section is C-shaped. A first stopper portion 5d is attached to the upper part of the first horizontal frame 52 via a bracket. The first stopper portion 5d engages with a second stopper portion 63b (described later), causing the first gate 5 to rise and fall together with the second gate 6.

[0031] The lower first horizontal frame 53 is a plate-like member bent so that its cross section is W-shaped. More specifically, the cross section of the lower first horizontal frame 53 includes a first attached portion 53a extending in the up-down direction D3 to which the first gate panel 50 and the first vertical frame 54 are attached, a front protruding portion 53b bending from the lower end of the first attached portion 53a and extending forward, and a hanging plate portion 53c bending from the front end of the front protruding portion 53b and extending downward. The cross section of the first horizontal frame 53 also includes a rear protruding portion 53d bending from the upper end of the first attached portion 53a and extending rearward.

[0032] The hanging plate portion 53c extends downward from the lower end of the first gate body 5a in the closed state, and has a length that positions the lower end of the hanging plate portion 53c below the reference position X3. By providing the first gate 5 with the hanging plate portion 53c extending downward from the lower edge of the first gate body 5a, it is possible to fill the gap between the first gate body 5a and the reference position X3 that occurs when the first gate body 5a is raised slightly above the reference position X3, and to prevent an obstacle from becoming caught in the gap.

[0033] The hanging plate portion 53c is formed by bending a portion of the first horizontal frame 53, eliminating the need for a separate member and reducing the number of parts. The hanging plate portion 53c, which is formed by bending the first horizontal frame 53 downward across the entire width in the left-right direction D1, also has the effect of suppressing deflection of the first horizontal frame 53 in the up-down direction D3.

[0034] Furthermore, the first gate 5 is provided with a front protrusion 53b extending forward from the lower edge of the first gate main body 5a, which can fill the gap between the front surface of the first gate main body 5a and the front wall surface X4a of the pit X4, thereby preventing obstacles from getting caught in the gap.

[0035] Furthermore, the front protruding portion 53b is formed by bending a portion of the first horizontal frame 53, eliminating the need for a separate member and reducing the number of parts. Note that the front protruding portion 53b, which is formed by bending the first horizontal frame 53 forward across the entire width in the left-right direction D1, also has the effect of suppressing deflection of the first horizontal frame 53 in the front-rear direction D2.

[0036] 8, the first vertical frame 54 is a plate-like member that has been bent so that its cross section is substantially C-shaped. The first vertical frame 54 includes an attachment portion 54a that extends in the left-right direction D1 and is attached to the first horizontal frames 52, 53, and a side wall portion 54b that bends from the outer end of the attachment portion 54a in the left-right direction D1 and extends forward.

[0037] The side wall portion 54b is disposed so as to face the recessed portion 43 of the first support pillar 4a and the second support pillar 4b. Here, "facing the side wall portion 54b with the recessed portion 43" means that the side wall portion 54b is disposed so as to reduce the opening area of ​​the recessed portion 43. That is, as shown in FIG. 8, the side wall portion 54b may be disposed inside the recessed portion 43, or conversely, the side wall portion 54b may be disposed outside the recessed portion 43. By providing the first gate 5 with the side wall portion 54b extending forward from the side edge of the first gate main body 5a in the left-right direction D1, it is possible to fill the gap between the first gate 5 and the first support pillar 4a and the second support pillar 4b, specifically the gap between the front surface of the first gate main body 5a and the flanges 41 of the first support pillar 4a and the second support pillar 4b, and to prevent an obstacle from becoming caught in the gap.

[0038] Moreover, the side wall portion 54b is formed by bending a portion of the first vertical frame 54, eliminating the need for a separate member and reducing the number of parts. Note that the side wall portion 54b, which is formed by bending the first vertical frame 54 forward over the entire height in the up-down direction D3, also has the effect of suppressing deflection of the first vertical frame 54 in the front-to-rear direction D2.

[0039] The first vertical frame 54 also includes a gate guide rail 5b with an L-shaped cross section at the inner end of the mounting portion 54a in the left-right direction D1. The gate guide rail 5b extends in the up-down direction D3. The gate guide rail 5b includes a first portion 54c that bends from the inner end of the mounting portion 54a in the left-right direction D1 and extends forward, and a second portion 54d that bends from the front end of the first portion 54c and extends outward in the left-right direction D1.

[0040] The gate rollers 5c are rotatably attached to both ends of the first gate body 5a in the left-right direction D1. The rotation axes of the gate rollers 5c are arranged along the front-rear direction D2. The gate rollers 5c are attached one by one in the up-down direction D3. The gate rollers 5c have grooves 50c that extend around the entire circumference of their outer surfaces. A support guide rail 42 is arranged in the grooves 50c of the gate rollers 5c, so that the gate rollers 5c are guided in the up-down direction D3 by the support guide rail 42. As a result, the first gate 5 can be raised and lowered in a stable position relative to the support pillars 4a and 4b.

[0041] In this embodiment, the second gate 6 moves up and down in front of the first gate 5. The second gate 6 includes a second gate body 6a, a lower guide roller 6b (an example of a first guide portion) fixed to the second gate body 6a, and a gate roller 6c fixed to the second gate body 6a.

[0042] The second gate body 6a includes a second gate panel 60 and a second gate frame 61 that surrounds the second gate panel 60. The second gate panel 60 is formed from a thin plate-like member, and has a large number of through holes formed in a portion thereof.

[0043] The second gate frame 61 comprises a pair of second horizontal frames 62, 63 whose length in the left-right direction D1 is approximately the same as the length between the first support pillar 4a and the second support pillar 4b, and a pair of second vertical frames 64, 64 connecting both ends of the pair of second horizontal frames 62, 63 in the left-right direction D1.

[0044] The pair of second horizontal frames 62, 63 are spaced apart in the vertical direction D3. The second gate panel 60 and the pair of second vertical frames 64, 64 are fixed to the front sides of the pair of second horizontal frames 62, 63.

[0045] 7, the upper second horizontal frame 62 is a plate-like member bent so that its cross section is substantially C-shaped. The lower second horizontal frame 63 is also a plate-like member bent so that its cross section is C-shaped. More specifically, the cross section of the lower second horizontal frame 63 includes a second attached portion 63a extending in the up-down direction D3 to which the second gate panel 60 and the second vertical frame 64 are attached, a second stopper portion 63b bending from the upper end of the second attached portion 63a and extending rearward, and a rear protruding portion 63c bending from the lower end of the second attached portion 63a and extending rearward.

[0046] The second gate 6 is provided with a rear protrusion 63c that extends rearward from the lower edge of the second gate main body 6a toward the first gate 5, thereby filling the gap between the lower edge of the second gate main body 6a and the front surface of the first gate main body 5a, thereby preventing obstacles from getting caught in the gap.

[0047] The rear protruding portion 63c is formed by bending a portion of the second horizontal frame 63, eliminating the need for a separate member and reducing the number of parts. The rear protruding portion 63c, which is formed by bending the second horizontal frame 63 rearward across the entire width in the left-right direction D1, also has the effect of suppressing deflection of the second horizontal frame 63 in the front-rear direction D2.

[0048] The second vertical frame 64 is a plate-like member that is bent so that its cross section is L-shaped, as shown in Fig. 8. By making the cross section L-shaped, the strength of the second vertical frame 64 is ensured.

[0049] The lower guide rollers 6b are rotatably attached to both ends of the second gate body 6a in the left-right direction D1. The lower guide rollers 6b are arranged so as not to overlap the gate rollers 5c when viewed in the up-down direction D3. The lower guide rollers 6b have grooves 60b extending around the entire circumference of their outer surfaces. The second portions 54d of the gate guide rails 5b are arranged in the grooves 60b of the lower guide rollers 6b, so that the lower guide rollers 6b are guided in the up-down direction D3 by the gate guide rails 5b. As a result, the first gate 5 and the second gate 6 can be raised and lowered in stable positions substantially parallel to each other.

[0050] The first portion 54c of the gate guide rail 5b abuts against the outer peripheral surface of the lower guide roller 6b in the left-right direction D1, thereby restricting movement of the lower guide roller 6b in the left-right direction D1. Furthermore, the second portion 54d of the gate guide rail 5b may also abut against the groove bottom of the groove 60b of the lower guide roller 6b in the left-right direction D1, thereby restricting movement of the lower guide roller 6b in the left-right direction D1. Furthermore, the second portion 54d of the gate guide rail 5b abuts against the groove wall surface of the groove 60b of the lower guide roller 6b in the front-rear direction D2, thereby restricting movement of the lower guide roller 6b in the front-rear direction D2.

[0051] The gate rollers 6c are rotatably attached to both ends of the second gate main body 6a in the left-right direction D1. The rotation axis of the gate rollers 6c is arranged along the front-rear direction D2. The gate rollers 6c are attached to the second gate main body 6a via brackets 61c (see FIG. 6) so that they overlap with the gate rollers 5c when viewed in the up-down direction D3. The gate rollers 6c have grooves 60c extending around the entire periphery of their outer surfaces. A support guide rail 42 is arranged in the grooves 60c of the gate rollers 6c, thereby guiding the gate rollers 6c in the up-down direction D3 by the support guide rail 42. As a result, the second gate 6 can be raised and lowered while maintaining a stable posture relative to the support pillars 4a and 4b.

[0052] Gate sheaves 7c and 7d are rotatably attached to the upper end of the second gate 6. The gate sheaves 7c and 7d are provided at both ends in the left-right direction D1 of the second gate 6. The rotation axes of the gate sheaves 7c and 7d are arranged along the front-rear direction D2.

[0053] A rope fixing portion 7b to which a first end of the rope 7a is fixed is attached to the upper end of the first support pole 4a.

[0054] The support sheave 7e is attached to the upper end of the second support column 4b. The rotation axis of the support sheave 7e is arranged along the front-to-rear direction D2. The support sheave 7f is attached to the lower end of the second support column 4b. The rotation axis of the support sheave 7f is arranged along the left-to-right direction D1. In other words, the rotation axis of the support sheave 7f is perpendicular to the rotation axis of the support sheave 7e when viewed in the up-down direction D3.

[0055] The drive unit 7g is attached to the back side of the second support column 4b, above the support column sheave 7f. The drive unit 7g is a winding device equipped with a drum and a motor that rotates the drum. The rotation axis of the drum is disposed along the front-to-rear direction D2. In other words, the rotation axis of the drum is approximately perpendicular to the rotation axis of the support column sheave 7f when viewed in the up-down direction D3.

[0056] 9, the rope 7a has a first end fixed to the rope fixing portion 7b of the first support pillar 4a, is stretched across gate sheaves 7c and 7d of the second gate 6 located below the rope fixing portion 7b, and is wound around the support pillar sheave 7e of the second support pillar 4b located above the gate sheaves 7c and 7d. In other words, the rope 7a is arranged in a substantially U-shape when viewed in the front-rear direction D2.

[0057] The rope 7a wound around the support sheave 7e is wound around the support sheave 7f, and then the second end is connected to the drum of the drive unit 7g. This allows the gates 5 and 6 to be raised and lowered with a small number of parts: one rope 7a and one drive unit 7g.

[0058] It is preferable to provide a safety device (not shown) that prevents the gates 5 and 6 from falling if the rope 7a breaks. One example of a safety device is a mechanism that, when an abnormality in the falling speed of the gates 5 and 6 is detected, protrusions appear from the supports 4a and 4b to support the gates 5 and 6.

[0059] As described above, the parking facility gate device 3 of this embodiment comprises a first support pillar 4a and a second support pillar 4b that are arranged at a distance in a first horizontal direction D1, and a first gate 5 and a second gate 6 that are arranged between the first support pillar 4a and the second support pillar 4b and move in an up-down direction D3 relative to the first support pillar 4a and the second support pillar 4b, the first gate 5 and the second gate 6 are arranged side by side in a second horizontal direction D2 that is perpendicular to the first horizontal direction D1, the first gate 5 comprises a first guide rail (in this embodiment, a gate guide rail) 5b that extends in the up-down direction D3, and the second gate 6 comprises a first guide portion (in this embodiment, a lower guide roller) 6b that is guided by the first guide rail.

[0060] According to this configuration, the first guide portion 6b of the second gate 6 is guided by the first guide rail 5b of the first gate 5, so that the first gate 5 and the second gate 6 can be raised and lowered in a stable position approximately parallel to each other.

[0061] In addition, in the parking facility gate device 3 of this embodiment, the first guide rail (in this embodiment, gate guide rail) 5b is provided at both ends of the first gate 5 in the first horizontal direction D1, and the first guide portion (in this embodiment, lower guide roller) 6b is provided at both ends of the second gate 6 in the first horizontal direction D1.

[0062] According to this configuration, the first guide portions 6b at both ends of the second gate 6 in the first horizontal direction D1 are guided by the first guide rails 5b at both ends of the first gate 5 in the first horizontal direction D1, respectively, so that the first gate 5 and the second gate 6 can be raised and lowered in a stable position approximately parallel to each other.

[0063] In addition, in the parking facility gate device 3 of this embodiment, the first guide rail (in this embodiment, gate guide rail) 5b has an L-shaped cross section consisting of a first portion 54c that contacts the first guide portion 6b in the first lateral direction D1 to regulate the movement of the first guide portion (in this embodiment, lower guide roller) 6b in the first lateral direction D1, and a second portion 54d that contacts the first guide portion 6b in the second lateral direction D2 to regulate the movement of the first guide portion 6b in the second lateral direction D2.

[0064] With this configuration, the movement of the second gate 6 relative to the first gate 5 in the first lateral direction D1 and the second lateral direction D2 can be restricted, so that the first gate 5 and the second gate 6 can be raised and lowered while maintaining a stable posture approximately parallel to each other.

[0065] In addition, in the parking facility gate device 3 of this embodiment, the first support pillar 4a and the second support pillar 4b are provided with a second guide rail (in this embodiment, a support pillar guide rail) 42 extending in the vertical direction D3, the first gate 6 is provided with a second guide portion (in this embodiment, a gate roller) 5c guided by the second guide rail 42, and the first guide portion 6b does not overlap with the second guide portion 5c when viewed in the vertical direction D3.

[0066] With this configuration, the first guide portion 6b does not come into contact with the second guide portion 5c even when it moves in the vertical direction D3, so that when the first gate 5 and the second gate 6 are in the open position, the overlap between them in the vertical direction can be reduced, thereby increasing the height of the gates in the open state.

[0067] As described above, the parking device 1 according to this embodiment includes the gate device 3 for the parking device.

[0068] According to this configuration, the first gate 5 and the second gate 6 can be raised and lowered while maintaining a stable posture substantially parallel to each other.

The scope of the present invention is defined not only by the description of the above embodiments but also by the claims, and further includes all modifications within the meaning and scope of the claims.

[0070] The structures employed in the above-described embodiments can be employed in any other embodiment.
