Description

Horizontal circulation parking device

[0001] The present invention relates to a horizontal circulation type parking device, and more particularly to a horizontal circulation type parking device equipped with a drainage function that can drain moisture brought into the parking device by vehicles to the outside.

[0002] As a parking system that can effectively utilize the underground space and upper floors of a building, a multi-story parking system has been constructed in which vehicle storage space is arranged on multiple levels and vehicles are moved within each level using carriages to enter and exit the parking system.

[0003] However, vehicles entering a parking device may be covered in moisture such as rainwater or snow. In this case, moisture may fall from the vehicles stored in the upper storage space and soil the vehicles stored in the lower storage space. For this reason, parking devices equipped with a drainage function that can drain moisture brought into the parking device by vehicles to the outside have been proposed.

[0004] The parking device described in Patent Document 1 is a flat-surface reciprocating parking device equipped with a drainage device. The drainage device includes a water receiving deck, a water receiving container, and a drainage pipe. The water receiving deck separates the upper and lower tracks and has an opening that receives water dropped from a traveling carriage carrying a vehicle and traveling horizontally on the track, and then drops the water downward. The water receiving container is located below the opening of the water receiving deck and collects water that drops from the water receiving deck. The drainage pipe drains the water from the water receiving container to the outside.

[0005] Patent No. 5885497

[0006] However, the parking system described in Patent Document 1 has a problem in that the water receiving decks are only located on the runways, so water that falls from vehicles stored in the storage space cannot be drained to the outside. Also, because the parking system described in Patent Document 1 has a problem in that the water receiving decks are only located on the runways, it cannot be applied to horizontal circulation type parking systems that do not have predetermined runways.

[0007] The present invention was made in consideration of the problems associated with such conventional technology, and aims to provide a horizontal circulation type parking device that can drain moisture brought into the parking device by vehicles to the outside.

[0008] According to one aspect of the present invention, there is provided a horizontal circulation type parking device comprising: a plurality of levels forming a space for storing vehicles; a pallet on which the vehicles are placed; a transport mechanism for moving the pallet vertically and horizontally within each level; a deck plate arranged between a lower level which is a relatively lower level and an upper level which is a relatively higher level; brackets arranged on a device frame and supporting the deck plate; a eaves gutter arranged along the width direction of the vehicle and for receiving moisture flowing from the deck plate; and a drain pipe for draining moisture collected in the eaves gutter to the outside.

[0009] According to one aspect of the present invention, a horizontal circulation type parking device can be provided that can drain moisture brought into the parking device by vehicles to the outside.

[0010] Fig. 1 is a side view of a horizontal circulation type parking device according to a first embodiment. Fig. 2 is a plan view of the horizontal circulation type parking device shown in Fig. 1. Fig. 3 is a front view of the horizontal circulation type parking device shown in Fig. 1. Fig. 4 is a side view of a horizontal circulation type parking device according to a second embodiment. Fig. 5 is a plan view of the horizontal circulation type parking device shown in Fig. 4. Fig. 6 is a front view of the horizontal circulation type parking device shown in Fig. 4.

[0011] First and second embodiments of the present invention will be described below with reference to FIGS.

[0012] (First embodiment) Fig. 1 is a side view of a horizontal circulation type parking device 1 according to the first embodiment. Fig. 2 is a plan view of the horizontal circulation type parking device 1 shown in Fig. 1. Fig. 3 is a front view of the horizontal circulation type parking device 1 shown in Fig. 1.

[0013] 1 to 3, when a vehicle is stored in the storage space of the horizontal circulation type parking system 1, the direction corresponding to the length of the vehicle is defined as the X direction, the direction corresponding to the width of the vehicle is defined as the Y direction, and the direction corresponding to the height of the vehicle is defined as the Z direction. The X direction, Y direction, and Z direction are perpendicular to each other.

[0014] The X and Y directions also correspond to the vertical (depth) and horizontal (width) directions on a plane within each level, respectively, as will be described later. Therefore, the X and Y directions are also referred to as the vertical and horizontal directions within the level. The Z direction also corresponds to the height direction of the level, which is perpendicular to the plane within each level.

[0015] As shown in Figures 1 to 3, the horizontal circulation type parking device 1 has multiple floors that form a space for storing vehicles, and each floor is equipped with multiple pallets 2, multiple conveying mechanisms 3, multiple deck plates 4, multiple brackets 5, multiple eaves gutters 6, and multiple drainage pipes 7.

[0016] A vehicle is placed on each pallet 2. Each transport mechanism 3 moves the corresponding pallet 2 vertically (X direction) and horizontally (Y direction) within the story. Each deck plate 4 is disposed between a lower story 11, which is the relatively lower story, and an upper story 12, which is the relatively higher story, of two adjacent stories. Each bracket 5 is disposed on a corresponding device frame 14 and supports the corresponding deck plate 4. Each eaves gutter 6 is disposed along the width direction (Y direction) of the vehicle and receives moisture flowing from the corresponding deck plate 4 via the corresponding bracket 5. Each drain pipe 7 discharges moisture collected in the corresponding eaves gutter 6 to the outside.

[0017] In a plan view of the horizontal circulation type parking system 1, each deck plate 4 is formed in a rectangular shape (see FIG. 2). Each deck plate 4 has at least one storage area along the vertical direction (X direction) within the level. One storage area stores one vehicle placed on one pallet 2. With this configuration, the X direction, Y direction, and Z direction shown in FIGS. 1 to 3 correspond to the longitudinal direction, width direction, and thickness direction of the deck plate 4, respectively.

[0018] A pair of brackets 5 extending along the vertical direction (X direction) of the floor are fixed to both sides of each deck plate 4 in the horizontal direction (Y direction) of the floor. With this configuration, the pair of brackets 5 are arranged side by side with the deck plate 4. In this state, the length of each bracket 5 in the vertical direction (X direction) of the floor is set to be greater than the length of the deck plate 4. In other words, both ends of each bracket 5 protrude outward beyond both ends of the deck plate 4 in the vertical direction (X direction) of the floor.

[0019] Two eaves gutters 6 extending in the horizontal direction (Y direction) within the story are arranged below both ends of a pair of brackets 5 that protrude outward beyond both ends of each deck plate 4 in the vertical direction (X direction) within the story. One end of a drain pipe 7 opens into the bottom surface on one end side of each eaves gutter 6. The other end of the drain pipe 7 opens to the outside.

[0020] As shown in Figure 2, the horizontal circulation type parking system 1 includes an elevator shaft 13 that transports vehicles placed on pallets 2 to each floor, and a plurality of device stands 14 that form the multi-level structure of the horizontal circulation type parking system 1. An elevator lift (not shown) is arranged in the elevator shaft 13. The plurality of device stands 14 include structural members such as vertically arranged steel members and horizontally arranged steel members. Multiple floors are formed by combining the plurality of device stands 14. Note that the arrangement and configuration of the elevator shaft 13 and the plurality of device stands 14 are not limited to the arrangement and configuration shown in Figures 1 to 3.

[0021] A vehicle is placed on a pallet 2 at a loading / unloading entrance (not shown) and transported to a specific floor by a lift. Once transported to the specific floor, the pallet 2 is moved vertically (X direction) and horizontally (Y direction) within the specific floor by a transport mechanism 3 arranged on the specific floor based on instructions from a control device (not shown) to reach a specific storage area. In Figures 1 and 2, the configuration of the transport mechanism 3 is simplified for ease of explanation. Note that the configuration of the transport mechanism 3 is not limited to the configuration shown in Figures 1 and 2. In Figure 3, the transport mechanism 3 is omitted.

[0022] The horizontal circulation type parking system 1 includes at least two levels, and may include three or more levels. For ease of explanation, as described above, the relatively lower level of two adjacent levels will be referred to as the lower level 11, and the relatively higher level will be referred to as the upper level 12. Note that Figure 2 is a plan view of the horizontal circulation type parking system 1 as seen from the upper level 12 side.

[0023] Each deck plate 4 has a corrugated shape with alternating concave and convex portions. In this embodiment, the concave and convex portions of the deck plate 4 are arranged so as to be repeated along the longitudinal direction (X direction) of the deck plate 4. Note that the concave and convex portions of the deck plate 4 shown in Figure 1 are exaggerated for the sake of convenience of explanation, and are not limited to the shape and size shown in Figure 1.

[0024] With this configuration, the unevenness of the deck plate 4 forms multiple grooves in the width direction (Y direction) of the deck plate 4. When the deck plate 4 is made up of multiple divided members in the longitudinal direction (X direction) of the deck plate 4, the multiple divided members are connected in the longitudinal direction (X direction) of the deck plate 4 by overlapping the unevenness formed on the end of one of two adjacent divided members with the unevenness formed on the end of the other divided member.

[0025] By forming the deck plate 4 in a corrugated shape, the unevenness formed on the end of one of two adjacent segments can be overlapped with the unevenness formed on the end of the other segment. This makes it possible to prevent water from leaking from the area where the two segments overlap on the deck plate 4. Furthermore, by forming the deck plate 4 in a corrugated shape, it is possible to form multiple grooves for draining water that falls from the vehicle. Note that the shape of the deck plate 4 is not limited to a corrugated shape, and it may be flat or have partial unevenness.

[0026] As described above, a pair of brackets 5 are fixed to both sides of each deck plate 4. Each pair of brackets 5 is a support member that supports the corresponding deck plate 4. One end of each bracket 5 is fixed to the equipment frame 14, and the other end of the bracket 5 is fixed to the deck plate 4.

[0027] Specifically, in a cross-sectional view of the bracket 5, the bracket 5 is formed in a generally U-shape with a downward convex shape, and has a bottom 5a and wall portions 5b and 5c (see FIG. 3). The wall portion 5b is located on one end of the bracket 5, stands upright from the bottom portion 5a, and has an end portion 5b1 that is fixed to the equipment stand 14. The wall portion 5c is located on the other end of the bracket 5, stands upright from the bottom portion 5a, and has an end portion 5c1 that is bent outward. The end portion 5c1 of the wall portion 5c is fixed to the underside of the deck plate 4. With this configuration, the bracket 5 supports the deck plate 4.

[0028] As shown in Figure 2, each bracket 5 is arranged along the longitudinal direction (X direction) of the deck plate 4 and has a duct portion 51 that guides moisture that has fallen from the deck plate 4 to the eaves gutter 6.

[0029] The duct portion 51 is configured, for example, by a groove having a downward convex shape, as shown in Fig. 3. By providing each bracket 5 with a duct function for guiding moisture, moisture that falls from the vehicle onto the deck plate 4 can be guided and collected via the duct portion 51 of each pair of brackets 5 to two eaves gutters 6 located below both ends of the pair of brackets 5.

[0030] The two eaves gutters 6 are gutters located below both ends of a pair of brackets 5. Each eaves gutter 6 extends in the horizontal direction (Y direction) within the floor and is fixed to the device frame 14. With this configuration, each eaves gutter 6 is located in a position where it can receive moisture flowing down from the duct portions 51 of at least two brackets 5 (see FIG. 2).

[0031] Each eaves gutter 6 may be arranged so as to be inclined in a predetermined direction to facilitate the flow of moisture into the drain pipe 7. Specifically, each eaves gutter 6 may be inclined in a predetermined direction so that one end of the drain pipe 7, which has an open bottom, is lower than the other end. Note that, considering that moisture received in each eaves gutter 6 is naturally washed away by flowing into the corresponding drain pipe 7, the eaves gutter 6 may be arranged substantially horizontally without being inclined.

[0032] Each drain pipe 7 is a drain pipe for guiding moisture collected in the corresponding eaves gutter 6 to the outside. Each drain pipe 7 is mainly arranged along the height direction (Z direction) of the floor. The upper end (one end) of each drain pipe 7 is connected to the corresponding eaves gutter 6 and opens to the bottom surface of one end side of the eaves gutter 6. The lower end (other end) of each drain pipe 7 is open to or connected to, for example, a drain outlet formed on the floor surface of the horizontal circulation type parking device 1 or in the building including the horizontal circulation type parking device 1.

[0033] Two drain pipes 7 may be connected to each eaves gutter 6 so that one end of the drain pipe 7 opens at the bottom surface of one end of the eaves gutter 6 and one end of another drain pipe 7 opens at the bottom surface of the other end of the eaves gutter 6. Also, three or more drain pipes 7 may be connected to each eaves gutter 6 so that one end of the drain pipe 7 opens at the bottom surface of one end of the eaves gutter 6, one end of another drain pipe 7 opens at the bottom surface of the other end of the eaves gutter 6, and one end of one or more other drain pipes 7 open at the bottom surface of the middle part of the eaves gutter 6. The arrangement and configuration of each drain pipe 7 are not limited to the configurations shown in Figures 1 to 3, and may be any configuration that can guide moisture collected in the corresponding eaves gutter 6 to the outside.

[0034] The multiple deck plates 4 and multiple brackets 5 may be configured to have enough strength to form a work scaffold (including an inspection walkway) during installation work and maintenance. As described above, in this embodiment, the multiple deck plates 4 are arranged over substantially the entire surface between the lower layer 11 and the upper layer 12. Therefore, by using the multiple deck plates 4 as a work scaffold, convenience and safety during work can be improved.

[0035] For example, the material and thickness of the deck plates 4 and brackets 5 may be adjusted so that the deck plates 4 and brackets 5 can withstand loads as scaffolding, or reinforcing materials may be placed on some of the deck plates 4 and brackets 5. Furthermore, the strength of only the portions of the deck plates 4 and brackets 5 that are used as scaffolding may be increased.

[0036] (Actions and Effects) According to this embodiment, the horizontal circulation type parking device 1 comprises multiple stories, a pallet 2, a transport mechanism 3, a deck plate 4, brackets 5, a gutter 6, and a drain pipe 7. The multiple stories form a space for storing vehicles. Vehicles are placed on the pallet 2. The transport mechanism 3 moves the pallet 2 vertically and horizontally within each story. The deck plate 4 is disposed between a lower story that is located relatively lower and an upper story that is located relatively higher. The bracket 5 is disposed on the device frame 14 and supports the deck plate 4. The gutter 6 is disposed along the width direction of the vehicle and receives moisture flowing from the deck plate 4. The drain pipe 7 drains moisture collected in the gutter 6 to the outside.

[0037] With the above-described configuration, by placing the deck plate 4 between the lower layer 11 and the upper layer 12 that form the space for storing vehicles, even if moisture is brought into the horizontal circulation type parking device 1 by the vehicle while it is moving or being stored, the moisture that falls from the upper layer 12 can be received by the deck plate 4 and can be drained to the outside through the eaves gutter 6 and drain pipe 7.

[0038] Furthermore, with the above-described configuration, a drainage function can be provided simply by adjusting the height between the lower layer 11 and the upper layer 12. Therefore, a drainage function can be easily provided in the horizontal circulation type parking device 1.

[0039] According to this embodiment, the deck plate 4 has a corrugated plate shape.

[0040] With the above-described configuration, it is possible to form a plurality of grooves for draining water that has fallen from the vehicle with a simple configuration.

[0041] According to this embodiment, the corrugated plate shape is formed by arranging concave and convex portions alternately along the length of the vehicle.

[0042] With the above-described configuration, even if the deck plate 4 is made up of multiple divided members in the length direction of the vehicle (the longitudinal direction of the deck plate 4), the irregularities formed on the end of one of two adjacent divided members can be overlapped with the irregularities formed on the end of the other divided member. This makes it possible to prevent water from leaking from the area of ​​the deck plate 4 where the two divided members are overlapped.

[0043] According to this embodiment, the bracket 5 has a duct portion 51 that is arranged along the longitudinal direction of the vehicle and guides moisture from the deck plate 4 to the eaves gutter 6 .

[0044] With the above-described configuration, moisture that falls onto the deck plate 4 from the vehicle can be guided and collected in the eaves gutter 6 via the duct portion 51 of the bracket 5. Therefore, even if moisture is brought into the horizontal circulation type parking device 1 by a vehicle, the moisture can be drained to the outside with a simple configuration.

[0045] According to this embodiment, the deck plate 4 and the bracket 5 are configured to have a strength sufficient to form a work scaffold.

[0046] With the above-described configuration, the deck plate 4 and the bracket 5 can also be used as a work platform, thereby improving convenience and safety during work.

[0047] (Second embodiment) Fig. 4 is a side view of a horizontal circulation type parking device 1A according to a second embodiment. Fig. 5 is a plan view of the horizontal circulation type parking device 1A shown in Fig. 4. Fig. 6 is a front view of the horizontal circulation type parking device 1A shown in Fig. 4.

[0048] 4 to 6, when a vehicle is stored in the storage space of the horizontal circulation type parking device 1A, the direction corresponding to the length of the vehicle is defined as the X direction, the direction corresponding to the width of the vehicle is defined as the Y direction, and the direction corresponding to the height of the vehicle is defined as the Z direction. The X direction, Y direction, and Z direction are perpendicular to each other.

[0049] The X and Y directions also correspond to the vertical (depth) and horizontal (width) directions on the plane of each story, and are therefore also referred to as the vertical and horizontal directions within the story. The Z direction also corresponds to the height direction of the story, which is perpendicular to the plane of each story.

[0050] 1 to 3, the horizontal circulation type parking device 1A shown in Figures 4 to 6 has a different arrangement of the deck plates 4, brackets 5, eaves gutters 6, and drainage pipes 7 on each floor due to a change in the direction of the repeated concaves and convexes of each deck plate 4. Note that, hereinafter, components that are the same as those of the horizontal circulation type parking device 1 will be assigned the same reference numerals and explanations thereof will be omitted where appropriate.

[0051] In this embodiment, in a plan view of the horizontal circulation type parking system 1A, each deck plate 4 is formed in a rectangular shape. Each deck plate 4 has one storage area along the vertical direction (X direction) within the level. One storage area stores one vehicle placed on one pallet 2. With this configuration, the X direction, Y direction, and Z direction shown in Figures 4 to 6 correspond to the longitudinal direction, width direction, and thickness direction of the deck plate 4, respectively.

[0052] The configuration of the storage areas provided on each deck plate 4 is not limited to the configuration shown in Figures 4 to 6. For example, multiple storage areas may be provided on each deck plate 4. In this case, the longitudinal length of the deck plate 4 will be greater than the longitudinal length of the deck plate 4 shown in Figures 4 and 5. Furthermore, in parts of the deck plate 4 where no storage areas are provided (for example, connecting parts connecting two storage spaces), the longitudinal length of the deck plate 4 (X direction) may be shorter than the length of one vehicle (see Figure 5).

[0053] A plurality of brackets 5 extending in the horizontal direction (Y direction) within the floor are fixed to each deck plate 4. Each bracket 5 is formed, for example, by a support member that spans between two adjacent equipment racks 14 among a plurality of equipment racks 14 arranged at predetermined intervals in the width direction (Y direction) within the floor. Note that, because each bracket 5 is arranged on the underside of the corresponding deck plate 4, each bracket 5 is omitted from Figure 5.

[0054] The number of brackets 5 is set according to the required strength. For example, on each deck plate 4, the brackets 5 may be arranged so that the portion forming the work scaffolding is denser than other portions. Note that on each deck plate 4, the brackets 5 may be arranged evenly in the longitudinal direction (X direction) of the deck plate 4.

[0055] Two eaves gutters 6 extending in the horizontal direction (Y direction) within the floor are arranged below both ends of each deck plate 4 in the vertical direction (X direction) within the floor. In this embodiment, each eaves gutter 6 receives moisture flowing directly from the corresponding deck plate 4 without going through a bracket 5. One end of a drain pipe 7 opens at the bottom surface on one end side of each eaves gutter 6. The other end of the drain pipe 7 opens to the outside. Note that in Figure 4, for ease of explanation, some of the multiple eaves gutters 6 and drain pipes 7 are shown with dashed lines.

[0056] Each deck plate 4 has a corrugated shape with alternating concave and convex portions. In this embodiment, the concave and convex portions of the deck plate 4 are arranged so as to be repeated along the width direction (Y direction) of the deck plate 4. Note that the concave and convex portions of the deck plate 4 shown in Figure 6 are exaggerated for the sake of convenience of explanation, and are not limited to the shape and size shown in Figure 6.

[0057] With this configuration, the unevenness of the deck plate 4 forms multiple grooves in the longitudinal direction (X direction) of the deck plate 4. When the deck plate 4 is made up of multiple divided members in the width direction (Y direction) of the deck plate 4, the multiple divided members are connected in the width direction (Y direction) of the deck plate 4 by overlapping the unevenness formed on the end of one of two adjacent divided members with the unevenness formed on the end of the other divided member.

[0058] Furthermore, this configuration allows the deck plates 4 to function as ducts that guide moisture to the two eaves gutters 6 located below both ends of each deck plate 4 in the longitudinal direction (X direction) of the deck plates 4. Therefore, there is no need for the brackets 5 to have a duct function, and the structure of the brackets 5 can be simplified.

[0059] 4 and 5, a shared eaves gutter 6 and drain pipe 7 may be arranged below the two opposing ends of two deck plates 4 adjacent in the vertical direction (X direction) on one floor. For example, a shared eaves gutter 6 and drain pipe 7 may be provided when arranging the eaves gutter 6 and drain pipe 7 in a narrow section, or when arranging the eaves gutter 6 and drain pipe 7 in a location where it is estimated that little water will flow down. If there is sufficient space, a shared eaves gutter 6 and drain pipe 7 may be arranged below each of the two opposing ends of two deck plates 4 adjacent in the vertical direction (X direction) on one floor.

[0060] (Operations and Effects) According to this embodiment, the corrugated plate shape is formed by arranging concave and convex portions alternately and repeatedly along the width direction of the vehicle.

[0061] With the above-described configuration, moisture that falls onto the deck plate 4 from the vehicle can be guided directly to and collected in the eaves gutters 6. This eliminates the need for the brackets 5 to have a duct function, allowing for a simplified structure of the brackets 5.

[0062] Furthermore, with the above-described configuration, even if the deck plate 4 is made up of multiple divided members in the width direction of the vehicle (width direction of the deck plate 4), the irregularities formed on the end of one of two adjacent divided members can be overlapped with the irregularities formed on the end of the other divided member. This makes it possible to prevent water from leaking from the area of ​​the deck plate 4 where the two divided members are overlapped.

[0063] According to this embodiment, the bracket 5 is disposed along the width direction of the vehicle.

[0064] With the above-described configuration, the bracket 5 can support the deck plate 4 with a simple configuration.

[0065] According to this embodiment, a plurality of brackets 5 are arranged along the width direction of the vehicle, and the brackets 5 are arranged more densely in the area forming the scaffolding than in other areas.

[0066] With the above-described configuration, the brackets 5 are densely arranged only in the portion that forms the scaffolding, which reduces the number of brackets 5 required to support the deck plate 4. This makes it possible to prevent an increase in manufacturing costs.

[0067] (Modification) In the first and second embodiments described above, the deck plate 4 is disposed between the lower layer 11 and the upper layer 12, but the present invention is not limited to this. If necessary, the deck plate 4 may be disposed between the floor surface on which the equipment rack 14 is disposed and the lowest layer.
