Description

Technical Field

[0001] The present invention relates to a three-dimensional parking device.

Background Art

[0002] Conventionally, a mechanical three-dimensional parking device that effectively utilizes limited space to park more vehicles is known. A three-dimensional parking device is a device that parks a plurality of vehicles three-dimensionally. Generally, it includes a frame structure composed of a plurality of columns, a plurality of pallets arranged to be movable (lift and / or traverse) inside the frame structure, and a gate that opens and closes an entrance / exit for the entry and exit of vehicles to and from the pallet.

[0003] Here, the above-mentioned entrance / exit is a part of the frame structure and is provided at a predetermined level (for example, the ground floor level) in the three-dimensional parking device. Also, the above-mentioned gate is configured to be able to open and close the entrance / exit, for example, by being lifted and lowered by a lifting device. Note that different authentication codes are pre-assigned to the plurality of pallets.

[0004] And in a three-dimensional parking device having such a configuration, when parking a vehicle (storing it), first, an authentication code is input into an operating device (operating means) to move a desired pallet to the entrance / exit. Then, the operating device is operated to open the gate. Next, the vehicle is allowed to enter through the entrance / exit and is loaded onto the pallet. After that, the operating device is operated again to close the gate, and the pallet carrying the vehicle is moved to a predetermined level. On the other hand, when retrieving a vehicle, first, an authentication code is input into the operating device to move the pallet carrying the desired vehicle to the entrance / exit. Then, the operating device is operated to open the gate. Next, the vehicle is allowed to exit through the entrance / exit. After that, the operating device is operated again to close the gate, and the pallet with the vehicle unloaded is moved to a predetermined level.

[0005] Furthermore, among mechanical multi-story parking systems, there are also puzzle-type multi-story parking systems in which each pallet is equipped with not only a lifting function but also a lateral function.

[0006] As an example of a multi-story parking system with such a configuration, Patent Document 1 discloses a parking system (multi-story parking system) in which a part of the frame structure is located in an underground space (pit), and a vehicle can be loaded onto a pallet and parked by opening an opening / closing gate (gate) and driving the vehicle into the system. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2020-200686 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] Incidentally, if a fire occurs in a multi-story parking system, and the fire site is surrounded by at least an underground space (pit), it is necessary to immediately open the gates, enter the system, and carry out firefighting activities such as spraying water into the underground space.

[0009] However, in the conventional multi-story parking system mentioned above, in order to open the gate by operating the operating device (operating means), it was first necessary to input an authentication code into the operating device (operating means), move a designated pallet to the entrance / exit, and then operate the operating device (operating means) again. In other words, only users who were given an authentication code and authorized to operate the gate could open it, which meant that it would take time to enter the device and could delay firefighting efforts.

[0010] This invention has been made in view of the problems of the current situation described above, and aims to provide a multi-story parking system that, for example, allows for immediate entry into the system and firefighting activities to be carried out if a fire occurs inside the system. [Means for solving the problem]

[0011] The problems that this invention aims to solve are as described above, and the means for solving these problems will now be explained.

[0012] That is, the multi-story parking device according to embodiment 1 of the present invention comprises a plurality of movable pallets, a gate that opens and closes an entrance / exit for vehicles to enter and exit the pallets, an operating means capable of performing an opening and closing operation of the gate, and a control means that opens and closes the gate based on the opening and closing operation by the operating means, wherein the control means performs an opening and closing operation of the gate based on the opening and closing operation by the operating means, and further comprises a fire detection means capable of detecting the occurrence of a fire inside the device, and an emergency operating means capable of opening the gate, wherein the control means permits the opening operation of the gate by the emergency operating means when the fire detection means detects a fire. With this configuration, the multi-story parking system according to the present invention eliminates the need, as in the conventional system, to first input an authentication code into the operating means, move a predetermined pallet to the entrance / exit, and then operate the operating means again (i.e., it is not limited to users who have been assigned an authentication code). Furthermore, if a fire is detected by the fire detection means, the gate can be immediately opened by opening the emergency operating means. Therefore, for example, if a fire occurs inside the device, the gate can be opened more quickly than before, allowing personnel to enter the device and immediately begin firefighting operations.

[0013] Furthermore, in the multi-story parking system according to embodiment 2 of the present invention, in embodiment 1, a plurality of gates are provided, and each can be opened and closed independently by the operating means, and when the control means executes an opening operation of the gates based on an opening operation by the emergency operating means, it executes the opening operation of all the gates simultaneously. With this configuration, the multi-story parking system according to the present invention allows for the simultaneous opening of multiple gates, enabling immediate entry into the system from multiple entrances and exits, and allowing for the more rapid and reliable commencement of firefighting operations.

[0014] Furthermore, in the multi-story parking system according to embodiment 3 of the present invention, in embodiment 1 or embodiment 2, the emergency operating means is provided integrally with the operating means, and is displayed on the touch panel provided on the operating means only when the fire detection means detects a fire. With this configuration, the multi-story parking system according to the present invention does not require the provision of separate dedicated operating devices as an emergency operating means, and can be operated using only the operating means used for operating the multi-story parking system during normal operation, thereby suppressing an increase in equipment costs.

[0015] Furthermore, in the multi-story parking system according to embodiment 4 of the present invention, in embodiment 1 or embodiment 2, the control means is characterized in that if the fire detection means detects a fire while the pallet is moving, it stops the pallet from moving. With this configuration, the multi-story parking system according to the present invention can prevent new malfunctions from occurring in the multi-story parking system due to the movement (lifting and / or traversing) of pallets in the event of a fire inside the system.

[0016] Furthermore, in the multi-story parking system according to embodiment 5 of the present invention, the control means is characterized in that, in embodiment 4, the control means gradually reduces the movement speed of the pallet and stops the movement of the pallet. With this configuration, according to the multi-story parking system of the present invention, if, for example, a fire occurs inside the system, the movement of the pallets can be stopped without placing an excessive load on the moving devices (e.g., lifting devices and / or traversing devices) that move the pallets (lifting and / or traversing), thereby more reliably preventing new malfunctions from occurring in the multi-story parking system.

[0017] Furthermore, in the multi-story parking device according to embodiment 6 of the present invention, in embodiment 1 or embodiment 2, the control means is characterized in that when an opening operation is performed by the emergency operation means, the operation means prohibits the closing operation of the gate. With this configuration, the multi-story parking system according to the present invention can prevent the gate from being unexpectedly closed by the operating means in the event of a fire inside the system, thereby preventing the firefighting efforts from being interrupted and enabling more reliable firefighting.

[0018] Furthermore, in the multi-story parking system according to embodiment 7 of the present invention, in embodiment 4 above, the control means is characterized in that when the fire detection means detects a fire or when the gate is in an open state, the operating means permits the movement of the pallet. With this configuration, according to the multi-story parking system of the present invention, if a fire occurs inside the system, for example, even if the fire is on an upper floor or in an underground space (pit), the pallets can be immediately moved to the appropriate position by operation using the operating means, and firefighting activities can be carried out reliably.

[0019] Furthermore, in embodiment 8 of the present invention, the multi-story parking device is characterized in that, in embodiment 1 or embodiment 2, the internal space of the multi-story parking device is pre-divided into a plurality of disaster prevention areas, a plurality of fire detection means are provided and arranged in each of the disaster prevention areas, the multi-story parking device further comprises a plurality of notification means capable of notifying the occurrence of a fire, and the plurality of notification means are arranged in each of the disaster prevention areas. With such a configuration, according to the three-dimensional parking device of the present invention, for example, when a fire breaks out in the device, the position of the fire site can be immediately grasped by the notification by the notification means, and the fire fighting activities can be carried out efficiently.

[0020] Further, the three-dimensional parking device according to Aspect 9 of the present invention, in the above Aspect 1 or the above Aspect 2, further includes gate moving means capable of executing the opening and closing operation of the gate, and the emergency operation means has a first transmission means capable of wirelessly transmitting an operation signal for operating the opening operation of the gate to the control means, and the control means has a first reception means capable of receiving the operation signal and a second transmission means capable of wirelessly transmitting an output signal for causing the gate moving means to execute the opening operation of the gate, and the gate moving means is characterized by having a second reception means capable of receiving the output signal. Here, when both the emergency operation means and the control means and the control means and the gate moving means are connected by wiring cables, for example, damage to the wiring cables due to a fire occurring in the device may make it difficult to open the gate by the emergency operation means. According to the three-dimensional parking device of the present invention, without using a wiring cable, through the first transmission means provided in the emergency operation means, the first reception means and the second transmission means provided in the control means, and the second reception means provided in the gate moving means, transmission and reception of electrical signals (operation signals and output signals) by wireless communication are possible. Therefore, there is no risk of difficulty in opening the gate as described above. When a fire breaks out in the device, the gate can be opened more reliably to enter the device and immediately start the fire extinguishing activities.

[0021] Further, the three-dimensional parking device according to Aspect 10 of the present invention, in the above Aspect 1 or the above Aspect 2, is characterized in that the fire detection means and / or the emergency operation means and the control means are connected to each other by a plurality of wiring cables. Here, when the fire detection means and / or the emergency operation means and the control means are connected by a single wiring cable, for example, if the wiring cable is damaged due to a fire occurring inside the device, there is a risk that it will be difficult to open the gate by the emergency operation means. According to the multi-story parking device of the present invention, since the fire detection means and / or the emergency operation means and the control means are connected by a plurality of wiring cables, even if some of the wiring cables are damaged due to a fire occurring inside the device, signals can be transmitted and received by the other wiring cables, and there is no risk of the above-mentioned difficulty in opening the gate. When a fire occurs inside the device, it is possible to more surely open the gate and enter the device, and immediately start the fire extinguishing activity.

Effects of the Invention

[0022] As an effect of the present invention, the following effects are achieved. That is, according to the multi-story parking device of the present invention, for example, when a fire occurs inside the device, it is possible to immediately enter the device and carry out the fire extinguishing activity.

[0024] Next, one embodiment of the present invention will be described using Figures 1 to 9. For convenience, the following explanation will refer to the side of the multi-story parking system 1 with its entrance / exit 13 as the front, and the front-to-back, left-to-right, and up-to-down directions of the multi-story parking system 1 will be defined and explained according to the directions of the arrows shown in Figures 1 to 3.

[0025] [Overall configuration of multi-story parking system 1] First, the overall configuration of the multi-story parking system 1 embodying the present invention will be explained using Figures 1 to 5.

[0026] In Figure 1, the multi-story parking system 1 is a mechanical multi-story parking system that parks multiple vehicles W·W··· vertically, and by arranging each vehicle W in a storage space S·S··· provided on multiple levels, it is a system that parks these multiple vehicles W·W··· simultaneously.

[0027] In this embodiment, the multi-story parking system 1 is a puzzle-type multi-story parking system, and as will be described later, each pallet 20 is equipped with not only a lifting function but also a traversing function, but is not limited to this. In other words, the configuration of the pallet 20 is not limited to this embodiment. For example, a storage space S located within the underground space V may be defined as a space exclusively for the movement of the pallet 20 when the vehicle W enters and exits the storage area, and the pallet may be configured to have only a lifting function provided by a predetermined pallet lifting device 21.

[0028] The multi-story parking system 1 mainly comprises a frame structure 10 that forms the skeleton of the main body of the system, a plurality of pallets 20·20··· arranged to be movable (in this embodiment, vertically and horizontally) inside the frame structure 10, an enclosure 30 that surrounds these plurality of pallets 20·20···, and a control unit 40 (see Figure 5) that controls the operation of the entire system.

[0029] The frame structure 10 has a plurality of support columns 11, 11, ... erected parallel to each other at predetermined intervals, and a plurality of beam members 12, 12, ... arranged between adjacent support columns 11, 11 and connecting these two members 11, 11. For example, in this embodiment, it is configured as a four-story structure. Furthermore, each support column 11 is made of a member with sufficient rigidity to support the load acting on the multi-story parking system 1, and in this embodiment, for example, H-shaped steel is used.

[0030] The number of floors comprised of the frame structure 10 is not limited to this embodiment; for example, it may be configured as a two-story, three-story, or five-story or more structure.

[0031] Furthermore, in this embodiment, the frame structure 10 is arranged such that the first floor F1, corresponding to the first floor, is located within the underground space (pit) V, and the second floor F2, third floor F3, and fourth floor F4, corresponding to the second floor and above, are located above ground, but it is not limited to this configuration. For example, the first layer F1 and the second layer F2 may be arranged so as to be located in the underground space V, or the first layer F1 to the third layer F3 may be located in the underground space V, and only the fourth layer F4 may be located above ground. Furthermore, the entirety of the first to fourth levels F1 to F4 may be arranged so as to be located above ground, rather than being located within the underground space V.

[0032] Furthermore, within the frame structure 10, multiple storage spaces S·S·S (three in this embodiment) capable of accommodating each vehicle W are provided at each respective level. Furthermore, at a predetermined level on the front side of the frame structure 10 (in this embodiment, the second level F2 located on the first floor above ground), a plurality of entrances and exits 13, 13, 13 (three in this embodiment) for loading and unloading vehicles W into and out of each pallet 20 are provided as part of the frame structure 10. Specifically, each entrance and exit 13 is formed by the space between adjacent support columns 11, 11 located on the front side of the frame structure 10.

[0033] The pallet 20 is used to load each vehicle W and move to a designated location, where the vehicle W is parked. As shown in Figures 3(a) and 3(b), the pallet 20 has a pallet body portion 20a on which the vehicle W is mounted, and a first closing portion 20b and a second closing portion 20c that close the gap between a pair of adjacent pallets 20-20.

[0034] The pallet body portion 20a consists of a rectangular member in plan view that extends in one direction (in this embodiment, in the front-rear direction), and has sufficient width to place a vehicle W along its longitudinal direction (front-rear direction).

[0035] The first closing portion 20b is, for example, made of a rectangular plate-shaped member bent into an inverted concave shape in cross-section, and is positioned along one end (the right end in this embodiment) in the width direction (the left-right direction in this embodiment) of the pallet body portion 20a. Furthermore, the first closing portion 20b is located slightly above the pallet body portion 20a and is supported by the pallet body portion 20a, protruding from the outer edge side (i.e., the right side) of the pallet body portion 20a.

[0036] The second closing portion 20c, like the first closing portion 20b, is made of, for example, a rectangular plate-shaped member bent into an inverted concave shape in cross-section, and is positioned along the other end (the left end in this embodiment) in the width direction of the pallet body portion 20a. Furthermore, the second closing portion 20c is located slightly above the pallet body portion 20a and slightly below the first closing portion 20b, and is supported by the pallet body portion 20a while protruding from the outer edge side (i.e., left side) of the pallet body portion 20a.

[0037] Furthermore, in a pair of adjacent pallets 20-20, the first closing portion 20b in one pallet 20 and the second closing portion 20c in the other pallet 20 are arranged to overlap each other in a plan view. As a result, the gap between the pair of pallets 20-20 is closed by the first closing part 20b and the second closing part 20c.

[0038] Furthermore, the first closure section 20b and the second closure section 20c are each provided with a predetermined inspection window. The inspection window provided in the first closure section 20b (hereinafter referred to as "first inspection window 20b1" as appropriate) and the inspection window provided in the second closure section 20c (hereinafter referred to as "second inspection window 20c1" as appropriate) are both located at the same position when the first closure section 20b and the second closure section 20c are arranged to overlap in a plan view.

[0039] The first inspection window 20b1 is closed by a first cover material 20b2, which is connected via a hinge, and can be opened and closed. Furthermore, the second inspection window 20c1 is closed by a removable second cover material 20c2, which can be opened and closed.

[0040] Furthermore, in the multi-story parking system 1, for example, if a fire occurs on the first level F1 located within the underground space V (see Figure 1), the first inspection window 20b1 and the second inspection window 20c1 can be immediately opened to insert a water hose or the like, allowing firefighting operations to begin.

[0041] As shown in Figure 1, the pallets 20, which have this configuration, are each placed in a storage space S inside the frame structure 10 and are configured to be able to be raised and lowered by a predetermined pallet lifting device 21. Furthermore, the pallet 20 is configured to be able to move horizontally by a pallet traversing device 22 (see Figure 4), which consists of a traversing rail provided on each level and drive wheels that can move on the traversing rail.

[0042] Since the pallet lifting device 21 and the pallet traversing device 22 described above both consist of known configurations, a detailed explanation will be omitted.

[0043] The enclosure 30 separates the inside from the outside of the multi-story parking device 1 (more specifically, the frame structure 10). The enclosure 30 comprises a gate 31, a guide mechanism 32 (see Figure 2) provided on the outer circumference of the gate 31, and a gate lifting device 33 capable of opening and closing the gate 31. The gate lifting device 33 is an example of a gate moving means according to the present invention.

[0044] Furthermore, the enclosure 30 includes a fence 34 that surrounds the area excluding the entrance 13 on at least one floor (in this embodiment, the second floor F2 located on the first floor above ground).

[0045] The gate 31 is provided at each of the multiple entrances 13, 13, 13 located in the frame structure 10, for example, and opens and closes each entrance 13. As shown in Figure 2, the gate 31 has a gate frame 31a formed in the shape of a rectangular frame and a panel member 31b that closes the inner circumference of the gate frame 31a.

[0046] The panel member 31b is formed from, for example, a rectangular plate-shaped member made of perforated metal (internally cut steel plate) or a grid-like mesh member.

[0047] The gate 31 is positioned at each entrance / exit 13 perpendicular to the vehicle W's entry / exit direction (front-to-back direction in this embodiment) and parallel to the vehicle W's width direction (left-to-right direction in this embodiment), and is configured to open and close each entrance / exit 13 by moving (raising and lowering) in the vertical direction by the gate lifting device 33.

[0048] Furthermore, the direction of movement of the gate 31 by the gate lifting device 33 is not limited to the vertical direction as in this embodiment, but may also be in the vehicle width direction (left-right direction).

[0049] The guide mechanism 32 regulates the raising and lowering position of the gate 31 when the gate lifting device 33 raises and lowers the gate 31. The guide mechanism 32 includes, for example, a pair of upper regulating rollers 32a and 32a positioned to protrude in the left-right direction at the top of the gate 31, and a pair of lower regulating rollers 32b and 32b positioned to protrude in the left-right direction at the bottom of the gate 31.

[0050] The upper regulating roller 32a is rotatable about its axis, with the axis direction being left-right, and is positioned between the flanges of the gate-side support column 33a, which will be described later.

[0051] Furthermore, when the gate 31 is raised and lowered by the gate lifting device 33, the upper regulating roller 32a slides between the flanges of the gate-side support column 33a, thereby regulating the deviation of the gate 31's raising and lowering posture in the front-rear direction.

[0052] The lower regulating roller 32b is rotatable about its axis, with the axis direction being the front-rear direction, and is positioned to contact the web of the gate-side support column 33a.

[0053] Furthermore, when the gate 31 is raised and lowered by the gate lifting device 33, the lower regulating roller 32b slides against the web of the gate-side support column 33a, thereby regulating the deviation of the gate 31's raising and lowering posture in the left-right direction.

[0054] The configuration of the guide mechanism 32 is not limited to this embodiment, and any configuration is acceptable as long as it is possible to restrict deviations in the forward / backward and left / right directions of the gate 31 when the gate lifting device 33 lifts and lowers the gate 31.

[0055] The gate lifting device 33 comprises, for example, a pair of gate-side support columns 33a·33a erected on both the left and right sides of the gate 31, a drive motor 33b provided as a drive source, and a suspension cable 33c for pulling the gate 31.

[0056] The gate-side support column 33a is made of a member with sufficient rigidity to support the load acting on the gate lifting device 33, and in this embodiment, for example, an H-shaped steel is used. The gate-side support column 33a may be provided separately to the frame structure 10 as a component of the gate lifting device 33, or it may be substituted by the support column 11 (see Figure 1) that constitutes the entrance / exit 13 of the frame structure 10.

[0057] The drive motor 33b is positioned at the upper end of a predetermined gate-side support column 33a, for example, with the axial direction of the drive shaft facing the front-rear direction. Furthermore, a sprocket 33b1 is mounted through the drive shaft.

[0058] The suspension cables 33c·33c are composed of drive chains and, for example, a pair (two cables) is provided for one gate lifting device 33. Each suspension cable 33c is connected at one end to the sprocket 33b1 of the drive motor 33b, and at the other end to the lower part of the gate 31.

[0059] Then, the drive motor 33b rotates the sprocket 33b1 in the forward direction, causing the gate 31 to rise from the second level F2 on the ground to the third level F3 via the suspension cable 33c, and the entrance / exit 13 opens. Furthermore, the drive motor 33b rotates the sprocket 33b1 in the reverse direction, causing the gate 31 to descend from the third level F3 to the second level F2 via the suspension cable 33c, and the entrance / exit 13 to close.

[0060] Furthermore, the configuration of the gate moving device 33 is not limited to this embodiment; any configuration that allows the gate 31 to be raised and lowered between the second level F2 and the third level F3 on the ground is acceptable. For example, the sprocket 33b1 and the suspension cable 33c may be constructed using a pulley and a timing belt, respectively, or the gate moving device 33 may be constructed using an electrically operated actuator that can move up and down, or a pneumatic or hydraulic actuator, etc.

[0061] As described above, the control unit 40 controls the operation of the entire multi-story parking system 1. As shown in Figure 4, the control unit 40 includes a control device 41, an operating device 42, a fire detector 43, and a fire alarm 44, etc. The control device 41 is an example of a control means according to the present invention. Furthermore, the fire detector 43 is an example of a fire detection means according to the present invention. Furthermore, the fire alarm 44 is an example of a notification means according to the present invention.

[0062] The control device 41 includes an arithmetic processing unit 41a composed of a CPU (Central Processing Unit), a storage unit 41b composed of ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), etc., and is electrically connected via wiring cables to various means of movement (pallet lifting device 21, pallet traversing device 22, and gate lifting device 33, etc.), an operating device 42 (described later), a fire detector 43, a fire alarm 44, etc.

[0063] The memory unit 41b pre-stores programs for operating the various means of movement described above based on operations by the main unit 42a and the unmanned confirmation device 42b, which will be described later, during normal times (for example, in normal conditions other than emergencies such as when a fire occurs inside the multi-story parking system 1), and programs for opening the gate 31 based on operations by the emergency gate opening device 42c, which will be described later, during emergencies such as when a fire occurs.

[0064] The control device 41 then performs calculation processing according to the program based on the operation signals (electrical signals) input from the operating device 42 and detection signals (electrical signals) input from various sensors such as the fire detector 43, and based on the calculation results of the calculation processing, it appropriately transmits output signals (electrical signals) to the various means of transport and the fire alarm 44, etc., to control the operation of the entire device.

[0065] The operating device 42 includes, for example, one main unit 42a installed on one support column 11 (or gate-side support column 33a) on the front side of the frame structure 10 and near the entrance / exit 13, and a plurality (two in this embodiment) of unmanned confirmation devices 42b, 42b installed on other support columns 11 (or gate-side support column 33a) (see Figure 2). Furthermore, the operating device 42 includes, for example, one emergency gate opening device 42c provided adjacent to the lower side of the main unit 42a (see Figure 5(a)). The main unit device 42a is an example of an operating means according to the present invention. Furthermore, the emergency gate opening device 42c is an example of an emergency operating means according to the present invention.

[0066] As shown in Figures 4 and 5(a), the main unit 42a includes an emergency stop switch 42a1, a touch panel 42a2, and a key switch 42a3, etc.

[0067] The emergency stop switch 42a1 is a switch that stops all operations (mechanical operations) in the multi-story parking system 1. When the emergency stop switch 42a1 is operated, the lifting, lowering, and traversing movements of each pallet 20 immediately stop. Also, when the emergency stop switch 42a1 is operated, the opening and closing movement of the gate 31 immediately stops, and the gate 31 stops at an intermediate opening or closing position.

[0068] The touch panel 42a2 is equipped with display and input functions, and for example, when a vehicle W is entering or leaving the facility, it is possible to input the authentication code (authentication number) of the pallet 20 on which the desired vehicle W is mounted (or will be mounted). Furthermore, the touch panel 42a2 can display the entered authentication code and various operation buttons, and can transmit the entered authentication code and operation signals (electrical signals) to the control device 41.

[0069] The various operation buttons displayed on the touch panel 42a2 include a safety confirmation completion button Z1, a pallet selection button Z2, a pallet call button Z3, an authentication code input button Z4, and a drive button Z5, which are displayed as appropriate depending on the operating status of the multi-story parking system 1.

[0070] The key switch 42a3 enables or disables the movement of each pallet 20 and the opening and closing of the gate 31 via the touch panel 42a2. The key switch 42a3 is provided with an engagement hole into which a predetermined safety key (not shown) can engage. By inserting the safety key into the engagement hole and rotating it in a predetermined direction, operation by the touch panel 42a2 can be enabled or disabled.

[0071] As shown in Figures 4 and 5(b), the unmanned verification device 42b has an unmanned verification button 42b1, etc. The unmanned confirmation button 42b1 releases the stopped state that temporarily halted the operation of the multi-story parking system 1, and restores it to an operational state.

[0072] Specifically, for example, if the emergency stop switch 42a1 is operated to temporarily stop all operations in the multi-story parking system 1, the system will be restored to an operational state by confirming that the inside of the system is unoccupied and then operating (pressing) the unoccupied confirmation button 42b1.

[0073] The emergency gate opening device 42c is a device that can only be operated in emergencies, such as when a fire occurs inside the multi-story parking system 1, and is a device that opens the gate 31. As shown in Figures 4 and 5(a), the emergency gate opening device 42c includes a gate opening button 42c1 and a protective cover 42c2 to prevent accidental operation of the gate opening button 42c1.

[0074] Furthermore, as will be described later, the emergency gate opening device 42c is authorized by the control device 41 to open the gate 31 only when the fire detector 43 detects a fire occurring inside the multi-story parking device 1. With the gate 31 opening operation permitted, opening the protective cover 42c2 and operating (pressing) the gate opening button 42c1 causes the multiple gates 31·31·31 provided at each entrance / exit 13 (three in this embodiment) to open simultaneously.

[0075] In this embodiment, the emergency gate opening device 42c is provided separately from the main unit 42a as an operating device exclusively for emergencies, but it is not limited to this configuration. For example, the emergency gate opening device (emergency operating means) 42c may be provided integrally with the main unit (operating means) 42a, and may be configured to display on the touch panel 42a2 provided on the main unit (operating means) 42a only when the fire detector (fire detection means) 43 detects a fire.

[0076] With this configuration, there is no need to provide separate, dedicated operating devices for the emergency gate opening device 42c. The main unit 42a, which operates the multi-story parking system 1 during normal operation, is sufficient, thus suppressing an increase in equipment costs.

[0077] Furthermore, although this embodiment provides one emergency gate opening device 42c, it is not limited to this, and multiple emergency gate opening devices 42c, 42c, etc. may be provided. Furthermore, the emergency gate opening device 42c may be provided in conjunction with the unmanned confirmation device 42b.

[0078] The fire detector 43 is used to detect the occurrence of a fire inside the multi-story parking system 1 and consists of a general-purpose thermal camera that can visually detect heat using infrared light. The configuration of the fire detector 43 is not limited to this embodiment, and may be composed of other general-purpose detectors, such as a differential spot-type detector that senses heat, a photoelectric spot-type detector that senses smoke, or an ultraviolet (or infrared) spot-type detector that directly detects flames.

[0079] As shown in Figure 2, multiple fire detectors 43, 43, etc. are provided, and are positioned in each of the multiple disaster prevention areas that have been pre-defined by partitioning the internal space of the multi-story parking device 1.

[0080] In this embodiment, the storage space S capable of accommodating each vehicle W described above is defined as a single disaster prevention area, and the multiple fire detectors 43, 43, ... are arranged in each of the multiple storage spaces S, S, ..., but are not limited to this. For example, multiple storage spaces S·S·S·S arranged in a vertical row across multiple layers (e.g., first layer F1 to fourth layer F4) may be defined as a single disaster prevention area, and multiple fire detectors 43·43··· may be placed in each storage space S located at the top layer (fourth layer F4) of each disaster prevention area.

[0081] The fire detector 43 monitors for the occurrence of a fire within the multi-story parking system 1, and if a fire occurs, it immediately detects it and transmits a detection signal to the control device 41.

[0082] The fire alarm 44 is used to notify the occurrence of a fire and consists of a general-purpose alarm lamp. The configuration of the fire alarm 44 is not limited to this embodiment, and may, for example, be composed of a general-purpose alarm buzzer or the like.

[0083] Multiple fire alarms 44·44·· are installed, and like the multiple fire detectors 43·43··, they are positioned in each of the multiple disaster prevention areas. In other words, multiple fire alarms 44·44··· are located in each of the multiple storage spaces S·S···.

[0084] The fire alarm 44 then operates based on the output signal from the control device 41, which has received a detection signal from the fire detector 43, and notifies the occurrence of a fire.

[0085] Thus, in this embodiment, the internal space of the multi-story parking device 1 is pre-divided into multiple disaster prevention areas (in this embodiment, storage spaces S), and multiple fire detectors (fire detection means) 43·43··· are provided and arranged in each of the disaster prevention areas. Furthermore, the multi-story parking system 1 is equipped with multiple fire alarms (notification means) 44·44·· capable of notifying of the occurrence of a fire, and these multiple fire alarms (notification means) 44·44·· are arranged in each of the aforementioned disaster prevention areas.

[0086] With this configuration, for example, if a fire occurs inside the multi-story parking system 1, the location of the fire can be immediately determined by the fire alarm 44, and firefighting operations can be carried out efficiently.

[0087] In the multi-story parking system 1 having the above configuration, the vehicle W entry (parking) operation is performed according to the following procedure.

[0088] Specifically, the user first enters an authentication code pre-assigned to each pallet 20 using the main unit 42a (more specifically, the touch panel 42a2; see Figure 4). When an authentication code is entered, the control device 41 moves the pallet lifting device 21 (see Figure 1) and the pallet traversing device 22 (see Figure 4) to lift and lower the desired pallet 20 and traverse it, moving the pallet 20 to a predetermined entrance / exit 13.

[0089] When the pallet 20 reaches the entrance / exit 13, the user uses the main unit device 42a (touch panel 42a2) to open the gate 31 located at the entrance / exit 13. When the gate 31 is opened, the control device 41 moves the gate lifting device 33 to open (lift) the gate 31.

[0090] When gate 31 is open, the user enters the multi-story parking device 1 through the entrance / exit 13 and loads the vehicle W onto the pallet 20. Once the vehicle W is loaded onto the pallet 20, the user again uses the main unit device 42a (touch panel 42a2) to close the gate 31.

[0091] When the gate 31 is closed, the control device 41 moves the gate lifting device 33 again to perform the closing (lowering) operation of the gate 31. Subsequently, the control device 41 moves the pallet lifting device 21 and the pallet traversing device 22 to lift and lower the pallet 20 and traverse it, moving the pallet 20 to a predetermined storage space S. This completes the series of procedures for parking vehicle W.

[0092] On the other hand, the process of retrieving vehicle W from the multi-story parking system 1 is carried out according to the following procedure.

[0093] Specifically, the worker first enters the authentication code of the pallet 20 on which the desired vehicle W is mounted using the main unit device 42a (more specifically, the touch panel 42a2). When an authentication code is entered, the control device 41 moves the pallet lifting device 21 and the pallet traversing device 22 to lift and lower the desired pallet 20 and traverse it, moving the pallet 20 to a predetermined entrance / exit 13.

[0094] When the pallet 20 reaches the entrance / exit 13, the user uses the main unit device 42a (touch panel 42a2) to open the gate 31 located at the entrance / exit 13. When the gate 31 is opened, the control device 41 moves the gate lifting device 33 to open (lift) the gate 31.

[0095] When gate 31 is open, users exit the multi-story parking system 1 from the interior through entrance / exit 13. After the vehicle W exits, the user uses the main unit 42a (touch panel 42a2) again to close the gate 31.

[0096] When the gate 31 is closed, the control device 41 moves the gate lifting device 33 again to perform the closing (lowering) operation of the gate 31. Subsequently, the control device 41 moves the pallet lifting device 21 and the pallet traversing device 22 to lift and lower and traverse the pallet 20, which no longer has a vehicle W on it, and move the pallet 20 to a predetermined storage space S. This completes the series of procedures for departing vehicle W.

[0097] As described above, in the multi-story parking system 1 of this embodiment, the entry and exit of vehicles W during normal operation is mainly performed by operating the main unit 42a, and the opening and closing of the gate 31 can only be performed after first inputting an authentication code via the main unit 42a and temporarily moving a predetermined pallet 20 to the entrance / exit 13. In other words, during the entry and exit of vehicles W during normal operation, only users who have been assigned an authentication code and are authorized to operate the gate 31 via the main unit 42a (touch panel 42a2) can open the gate 31. Furthermore, the opening and closing operation of the gate 31 by the main unit device 42a is configured to operate each of the multiple gates 31·31·31 individually.

[0098] In this embodiment, the gate 31 is opened and closed by entering an authentication code, but the invention is not limited to this configuration. In other words, the system only needs to be configured such that the opening and closing of gate 31 is permitted when certain release conditions are met, which are assigned (or known to) specific subscribers, manufacturers, management companies, or other administrators. These release conditions may be, for example, physical keys, IC cards, or non-physical PINs (passwords).

[0099] [Operation Procedure for Multi-story Parking System 1 in Emergency Situations] Next, the operating procedure of the multi-story parking system 1 in an emergency, such as when a fire occurs inside the multi-story parking system 1, will be explained using Figures 6 and 7.

[0100] In Figure 6, first, when the user performs the vehicle W entry and exit operation, they input an authentication code using the main unit device 42a and perform the operation to call the desired pallet 20 (step S01).

[0101] When a call operation is performed, the control device 41 determines whether or not there is a detection signal from the fire detector 43 and determines whether or not the fire detector 43 has detected a fire (step S02). As a result, if the fire detector 43 determines that a fire has been detected (YES determination), the control device 41 executes steps S05, S09, and S10 described later. On the other hand, if the fire detector 43 determines that no fire has been detected (NO determination), the control device 41 moves the pallet lifting device 21 and the pallet traversing device 22 to start moving the desired pallet 20 (step S03).

[0102] After the movement of the pallet 20 begins, the control device 41 continues to determine whether the fire detector 43 has detected a fire (step S04). As a result, as shown in Figure 7, if the fire detector 43 determines that it has not detected a fire (NO determination), the control device 41 continues to move the pallet 20 (step S21).

[0103] Here, the control device 41 constantly monitors for the presence or absence of a fire using the fire detector 43 while the pallet 20 is being moved. Specifically, if the control device 41 continues to move the pallet 20 in step S21, it determines whether the pallet 20 has reached a predetermined entrance / exit 13 (step S22). If it determines that the pallet 20 has not reached the predetermined entrance / exit 13 (NO determination), it executes step S04 again (see Figure 6) to repeatedly determine whether the fire detector 43 has detected a fire.

[0104] Then, in step S22, if the control device 41 determines that the pallet 20 has reached a predetermined entrance / exit 13 (YES determination), it permits the main unit device 42a to open the gate 31. Subsequently, the user uses the main unit 42a to open the gate 31 and perform the vehicle W entry and exit operation (step S23).

[0105] On the other hand, as shown in Figure 6, if the fire detector 43 determines in step S04 that a fire has been detected (YES determination), the control device 41 disables the operation by the main unit 42a and permits the opening operation of the gate 31 by the emergency gate opening device 42c (step S05). This makes it possible to immediately open the gate 31 using the emergency gate opening device 42c without having to enter an authentication code as in normal circumstances.

[0106] Subsequently, when the user operates the emergency gate opening device 42c (step S06), the control device 41 moves the gate lifting device 33 to simultaneously open all (3) gates 31·31·31 (step S07).

[0107] Furthermore, if the gate 31 is opened by the emergency gate opening device 42c in step S06, the control device 41 prohibits the closing operation of all (3) gates 31·31·31 by the main unit device 42a (step S08).

[0108] Thus, in this embodiment, multiple gates 31, 31, 31 are provided (three locations in this embodiment), and under normal circumstances, each gate can be opened and closed independently by the main body device (operating means) 42a. Furthermore, when the control device (control means) 41 executes an opening operation of gate 31 based on an opening operation by the emergency gate opening device (emergency operation means) 42c (step S06), it is configured to execute the opening operation of all gates 31·31·31 simultaneously (step S07).

[0109] With this configuration, the multi-story parking system 1 of this embodiment allows for the simultaneous opening of multiple gates 31, 31, and 31, enabling immediate entry into the system through multiple entrances 13, 13, and allowing for a quicker and more reliable commencement of firefighting operations.

[0110] Furthermore, in this embodiment, the control device (control means) 41 is configured to prohibit the closing operation of all (3 locations) gates 31·31·31 by the main unit device (operating means) 42a when an opening operation is performed by the emergency gate opening device (emergency operating means) 42c (step S06) (step S08).

[0111] With this configuration, according to the multi-story parking system 1 of this embodiment, if a fire occurs inside the system, for example, the gate 31 will not be unexpectedly closed by the main unit 42a, preventing the firefighting efforts from being interrupted, and thus enabling more reliable firefighting.

[0112] By the way, in step S04 above, if the fire detector 43 determines that a fire has been detected (YES determination), the control device 41 further activates the fire alarm 44 to notify the occurrence of a fire (step S09). Furthermore, the fire alarm 44 will continue to operate until the fire detection by the fire detector 43 is canceled.

[0113] Furthermore, based on the YES determination in step S04, the control device 41 stops the pallet lifting device 21 and the pallet traversing device 22, and temporarily halts the movement of the pallet 20 (lifting and traversing movements) (step S10). In this case, the control device 41 gradually reduces the movement speed of the pallet 20 (more specifically, the pallet lifting device 21 and the pallet traversing device 22) and temporarily stops the movement of the pallet 20 (lifting and traversing movements).

[0114] Thus, in this embodiment, the control device (control means) 41 is configured to stop the movement of the pallet 20 (in this embodiment, the lifting and traversing movement) (step S10) if the fire detector (fire detection means) 43 detects a fire (YES determination in step S04) while the pallet 20 is being lifted or lowered.

[0115] With this configuration, according to the multi-story parking system 1 of this embodiment, if, for example, a fire occurs inside the system, the rising and falling pallets 20 can prevent new malfunctions from occurring in the multi-story parking system 1.

[0116] Furthermore, in this embodiment, when the control device (control means) 41 temporarily stops the movement (lifting and traversing) of the pallet 20 by step S10, it is configured to gradually reduce the movement speed of the pallet 20 (pallet lifting device 21) while stopping the movement of the pallet 20.

[0117] With this configuration, according to the multi-story parking system 1 of this embodiment, if a fire occurs inside the system, for example, the movement of the pallet 20 (lifting and traversing) can be stopped without placing an excessive load on the pallet lifting device 21 that raises and lowers the pallet 20, and the pallet traversing device 22 that moves the pallet 20 horizontally. This makes it possible to more reliably prevent new malfunctions from occurring in the multi-story parking system 1.

[0118] After temporarily stopping the movement of the pallet 20 (lifting and traversing) in step S10, the control device 41 determines whether all gates 31, 31, 31 that were opened in step S07 are in the open state (step S11). As a result, if it is determined that all gates 31·31·31 are in the open state (YES determination), the control device 41 permits the main unit device 42a to move the pallet 20 (step S12). On the other hand, if the control device 41 determines that not all gates 31·31·31 are open (NO determination), it executes step S11 again.

[0119] In step S12, however, without requiring a YES determination in step S11, the movement operation of the pallet 20 by the main unit 42a may be immediately permitted based on a YES determination in step S04 indicating that the fire detector 43 has detected a fire.

[0120] Thus, in this embodiment, the control device (control means) 41 is configured to allow the main unit (operating means) 42a to move the pallet 20 (lifting and traversing operations) when the fire detector (fire detection means) 44 detects a fire (YES determination in step S04) or when all gates 31·31·31 are open (YES determination in step S11).

[0121] With this configuration, according to the multi-story parking system 1 of this embodiment, if a fire occurs inside the system, for example, even if the fire is on an upper floor or in an underground space (pit) V, the pallet 20 can be immediately moved to an appropriate position by operation of the main unit 42a, and firefighting activities can be carried out reliably.

[0122] The series of operations of the multi-story parking system 1 in an emergency is completed when the operations in steps S07, S08, S09, and S12 described above are completed. Subsequently, when the fire detection by the fire detector 43 is canceled, the control device 41 disables the opening operation of the gate 31 by the emergency gate opening device 42c and re-enables operation by the main unit device 42a under normal circumstances.

[0123] [Configuration of the multi-story parking system 101 (first alternative embodiment)] Next, the configuration of the multi-story parking system 101 in the first alternative embodiment will be explained with reference to Figure 8. The multi-story parking system 101 in the first alternative embodiment has substantially the same configuration as the multi-story parking system 1 in the above-described embodiment, but the configuration of the control unit 140 differs from that of the multi-story parking system 1. Therefore, the following description will mainly focus on the differences between this embodiment and the multi-story parking system 1, and will omit descriptions of configurations equivalent to those of the multi-story parking system 1.

[0124] In the multi-story parking system 101 of this separate embodiment, the control unit 140 mainly comprises a control device 141, an operating device 142, a fire detector 143, and a fire alarm 144, etc. Since the fire detector 143 and fire alarm 144 have substantially the same configuration as the fire detector 43 and fire alarm 44 in the embodiment described above, their descriptions are omitted.

[0125] The control device 141 is an example of a control means according to the present invention. The control device 141 includes an arithmetic processing unit 141a, a storage unit 141b, a first receiving means 141c, and a second transmitting means 141d. Since the arithmetic processing unit 141a and the storage unit 141b have substantially the same configuration as the arithmetic processing unit 41a and the storage unit 41b in the embodiment described above, a description of them will be omitted.

[0126] As will be described later, the first receiving means 141c enables wireless transmission of operation signals (electrical signals) to the emergency gate opening device 142c. Furthermore, the second transmission means 141d enables wireless transmission of output signals (electrical signals) to and from the gate lifting device 133.

[0127] Here, the gate lifting device 133 is an example of a gate moving means according to the present invention, and has a second receiving means 133d, which is configured to receive an output signal (electrical signal) transmitted from the second transmitting means 141d of the control device 141 via the second receiving means 133d. Since the gate lifting device 133 has substantially the same configuration as the gate lifting device 133 in the embodiment described above, a description of it will be omitted.

[0128] The operating device 142 includes a main unit 142a, an unmanned confirmation device 142b, and an emergency gate opening device 142c. Since the main unit 142a and the unmanned verification device 142b have substantially the same configuration as the main unit 42a and the unmanned verification device 42b in the above-described embodiment, their descriptions are omitted.

[0129] The emergency gate opening device 142c is an example of an emergency operating means according to the present invention, and has a first transmitting means 142c3, and is configured to transmit an operating signal (electrical signal) to the first receiving means 141c of the control device 141 via the first transmitting means 142c3. Since the emergency gate opening device 142c has substantially the same configuration as the emergency gate opening device 42c in this embodiment described above, a description of it will be omitted.

[0130] Thus, the multi-story parking system 1 in the first alternative embodiment is equipped with a gate lifting device (gate moving means) 133 capable of opening and closing the gate 31. Furthermore, the emergency gate opening device (emergency operating means) 142c has a first transmitting means 142c3 that can wirelessly transmit an operating signal to the control device (control means) 141 to operate the gate 31 opening operation. Furthermore, the control device (control means) 141 includes a first receiving means 141c capable of receiving the above-mentioned operation signal, and a second transmitting means 141d capable of wirelessly transmitting an output signal to the gate lifting device (gate moving means) 133 to cause the gate 31 to open. Furthermore, the gate lifting device (gate moving means) 133 has a second receiving means 133d capable of receiving the output signal.

[0131] In this case, if the emergency gate opening device 142c and the control device 141, and the control device 141 and the gate lifting device 133 are both connected by wiring cables, there is a risk that the wiring cables may be damaged by a fire occurring inside the multi-story parking system 101, for example, which could make it difficult for the emergency gate opening device 142c to open the gate 31.

[0132] According to the multi-story parking system 101 in this alternative embodiment, electrical signals (operation signals and output signals) can be transmitted and received wirelessly via the first transmitting means 142c3 provided in the emergency gate opening device 142c, the first receiving means 141c and the second transmitting means 141d provided in the control device 141, and the second receiving means 133d provided in the gate lifting device 133, without using wiring cables. Therefore, there is no risk of difficulty in opening the gate 31 as described above, and in the event of a fire inside the multi-story parking system 101, the gate 31 can be opened more reliably to enter the device and immediately begin firefighting activities.

[0133] As described above, the multi-story parking system 1 in this embodiment includes a plurality of pallets 20·20·· that are provided to be able to move up and down, a gate 31 that opens and closes an entrance / exit 13 for vehicles W to enter and exit the pallets 20, a main unit (operating means) 42a that can perform the opening and closing operation of the gate 31, and a control device (control means) 41 that opens and closes the gate 31 based on the opening and closing operation by the main unit (operating means) 42a. The control device (control means) 41 is configured to perform the opening and closing operation of the gate 31 based on the opening and closing operation by the main unit (operating means) 42a.

[0134] Furthermore, the multi-story parking system 1 is equipped with a fire detector (fire detection means) 43 capable of detecting the occurrence of a fire within the system, and an emergency gate opening device (emergency operation means) 42c capable of opening the gate 31. The control device (control means) 41 is configured to allow the emergency gate opening device (emergency operation means) 42c to open the gate 31 when the fire detector (fire detection means) 43 detects a fire.

[0135] With this configuration, the multi-story parking system 1 of this embodiment does not require, as in the conventional system, to first input an authentication code into the main unit 42a, move the predetermined pallet 20 to the entrance / exit 13, and then operate the main unit 42a again (i.e., it is not limited to users who have been assigned an authentication code). If a fire is detected by the fire detector 43, the gate 31 can be immediately opened by opening the emergency gate opening device 42c. Therefore, for example, if a fire occurs inside the multi-story parking system 1, the gate 31 can be opened more quickly than in the conventional system, allowing entry into the system and immediate commencement of firefighting operations.

[0136] [Configuration of Multi-story Parking System 201 (Second Alternative Embodiment)] Next, the configuration of the multi-story parking system 201 in the second alternative embodiment will be explained with reference to Figure 9. The multi-story parking system 201 in the second alternative embodiment also has a configuration substantially equivalent to the multi-story parking system 1 in the above-described embodiment, similar to the first alternative embodiment, but differs from the multi-story parking system 1 in the configuration of the control unit 240. Therefore, the following description will mainly focus on the differences between this embodiment and the multi-story parking system 1, and will omit descriptions of configurations equivalent to those of the multi-story parking system 1.

[0137] In the multi-story parking system 201 of this alternative embodiment, the control unit 240 mainly comprises a control device 241, an operating device 242, a fire detector 243, and a fire alarm 244, etc. Since the control device 241 and the fire alarm 244 have substantially the same configuration as the control device 41 and fire alarm 44 in the embodiment described above, their descriptions are omitted.

[0138] The operating device 242 includes a main unit 242a, an unmanned confirmation device 242b, and an emergency gate opening device 242c. Since the main unit 242a and the unmanned verification device 242b have substantially the same configuration as the main unit 42a and the unmanned verification device 42b in the above-described embodiment, their descriptions are omitted.

[0139] The emergency gate opening device 242c is an example of an emergency operating means according to the present invention, and is electrically connected to the control device 241 via a plurality of (three in this embodiment) wiring cables L1·L1·L1. The configuration of the emergency gate opening device 242c is substantially the same as that of the emergency gate opening device 242c in the embodiment described above, so a description is omitted.

[0140] The fire detector 243 is an example of a fire detection means according to the present invention, and, similar to the emergency gate opening device 242c, is electrically connected to the control device 241 via a plurality of (three in this embodiment) wiring cables L2·L2·L2. The configuration of the fire detector 243 is substantially the same as that of the fire detector 43 in the embodiment described above, so a description of it will be omitted.

[0141] In this embodiment, both the emergency gate opening device 242c and the fire detector 243 are connected to the control device 241 via multiple wiring cables (L1·L1·L1)·(L2·L2·L2), respectively. However, the embodiment is not limited to this, and for example, only one of the emergency gate opening device 242c and the fire detector 243 may be connected to the control device 241 via multiple wiring cables (L1·L1·L1) or (L2·L2·L2).

[0142] Thus, in the multi-story parking system 1 of the second alternative embodiment, the fire detector (fire detection means) 243 and / or the emergency gate opening device (emergency operation means) 242c and the control device (control means) 241 are connected to each other by a plurality of wiring cables (L1·L1·L1) and / or (L2·L2·L2).

[0143] In this case, if the fire detector 243 and / or the emergency gate opening device 242c are connected to the control device 241 by a single wiring cable, there is a risk that the wiring cable may be damaged by a fire occurring inside the multi-story parking system 201, making it difficult for the emergency gate opening device 242c to open the gate 31.

[0144] In the multi-story parking system 1 of this alternative embodiment, the fire detector 243 and / or emergency gate opening device 242c and the control device 241 are connected by multiple wiring cables (L1·L1·L1) and / or (L2·L2·L2). Therefore, even if some of the wiring cables L1 and / or L2 are damaged by a fire that occurs inside the multi-story parking system 201, signals can still be transmitted and received by the other wiring cables. This eliminates the risk of difficulty in opening the gate 31 as described above, and in the event of a fire inside the system, the gate can be opened more reliably to enter the system and immediately begin firefighting operations.

[0145] Although one embodiment of the present invention has been described above, the present invention is not limited in any way to this embodiment, but is merely illustrative, and can be implemented in various other forms without departing from the spirit of the invention. The scope of the present invention is indicated by the claims, and further includes the meaning of equivalents as described in the claims, and all modifications within that scope.

[0146] For example, a buzzer may be installed near gate 31, and in step S07 (see Figure 6) described above, when opening all (3) gates 31·31·31, the buzzer may be sounded to notify the user until the opening operation is complete.

[0147] Furthermore, in the multi-story parking system 1, if, for example, a fire occurs on the first level F1 located within the underground space V (see Figure 1), the opening operation of all (3) gates 31·31·31 may be performed in step S07, and at the same time, the pallet 20 located within the underground space V may be raised simultaneously.
