Description

[Technical field]

[0001] The present invention relates to a fire extinguishing system that is installed in a building such as a detached house to suppress and extinguish a fire. [Background technology]

[0002] Conventionally, fire extinguishers are installed in ordinary detached houses as fire extinguishing equipment. Also, sprinkler fire extinguishing equipment is known that uses tap water as a water source and releases tap water from a sprinkler head when a fire occurs to suppress and extinguish the fire. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-152261 A [Patent Document 2] JP 2012-179330 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with fire extinguishers, due to inexperience of the operator, it is not easy to accurately discharge the extinguishing agent toward the source of the fire, the discharged extinguishing agent may scatter over a wide area, resulting in insufficient extinguishing efficiency, and there is a possibility that the scattered extinguishing agent may cause secondary damage such as staining or damage to surrounding objects. In addition, if it takes time to notice a fire or the fire spreads rapidly, it is difficult to put out the fire in its initial stage with a fire extinguisher, and people must evacuate to the outdoors quickly. For example, even if people evacuate with a fire extinguisher, it is difficult to put out the fire from the outdoors.

[0005] In addition, sprinkler fire extinguishing equipment that uses tap water operates when the temperature rise caused by hot air currents meets the activation conditions, and does not activate until the scale of the fire has grown to a certain extent, so there is a problem that it is not necessarily possible to start extinguishing the fire early. Also, sprinkler heads spray water for extinguishing locally from the installation point, and when the amount of water sprayed per unit time is limited, as with tap water, it is difficult to ensure a sufficient spray range and amount, and there is a possibility that the fire cannot be sufficiently suppressed and extinguished.

It is characterized by: Effect of the Invention

[0030] (Basic Effects) In the fire extinguishing system of the present invention, when a fire breaks out, a user who has evacuated to the outdoors can pull out the safety pin of a fire extinguisher supply device installed outside the building, for example, a fire extinguisher, and hold the lever to open it (opening the valve), and the extinguishing agent discharged from the extinguisher is discharged through the extinguishing agent piping from the fire extinguisher installed in a room or the like that is a protected area where a fire has broken out inside the building, and the fire occurring inside the building can be suppressed and extinguished by operating the fire extinguisher outdoors. Even if the fire cannot be extinguished by operating the fire extinguisher outdoors, it is possible to hand over the fire extinguishing activities to the fire brigade that was dispatched in response to the fire report in a state where the fire has been suppressed, enabling efficient firefighting activities.

[0031] (Effect of outdoor control box) In addition, since the fire extinguishing agent supply equipment is stored in an outdoor control box installed outside the building, in the event of a fire, users or firefighters can open the indoor control box and turn on the stored fire extinguisher, for example a fire extinguisher, to release fire extinguishing agent into rooms within the building that are designated as protected areas where a fire is occurring, thereby making it possible to contain and extinguish the fire within the building.

[0032] (Effect of outdoor control box configuration 1) In addition, the extinguishing agent supplying device stored in the outdoor operation box, for example, a fire extinguisher, is detachably connected to the extinguishing agent pipes provided for each protected compartment, and the corresponding relationship between the fire extinguisher and the protected compartment is displayed on the operation display unit, so that in the event of a fire, a user can look at the operation display unit to confirm the fire extinguisher corresponding to the protected compartment where the fire has occurred and open the valve, thereby enabling the extinguishing agent to be reliably discharged from the fire extinguisher in the protected compartment where the fire has occurred in the building. In addition, in a situation where the fire spreads, the spread of the fire can be suppressed by selecting and opening the fire extinguisher corresponding to the rooms surrounding the protected compartment where the fire has occurred.

[0033] (Effect of outdoor control box configuration 2) In addition, the outdoor operation box connects a plurality of extinguishing agent supply devices, for example a plurality of fire extinguishers, to a common piping, and connects extinguishing agent piping to the fire extinguishers for each protected compartment from the common piping, and provides a piping opening / closing means for each extinguishing agent piping. By operating the piping opening / closing means corresponding to the specific protected compartment in which a fire has occurred to the open state, and in this state opening the fire extinguisher connected to the common piping to release the extinguishing agent, if the fire is not sufficiently suppressed and extinguished even after the release of the extinguishing agent has been completed, the release of the extinguishing agent can be continued by repeating the operation of opening the next fire extinguisher, and the continuous release of extinguishing agent equivalent to the number of fire extinguishers stored in the outdoor operation box makes it possible to more reliably suppress and extinguish a fire.

[0034] (Effect of discharge compartment indicator light) In addition, a release indicator light is provided on the operation display section of the indoor operation box, and the release compartment indicator light is activated by an operation detector that detects the operation of the fire extinguishing equipment, making it easy to confirm from the outdoor operation box that extinguishing agent is being reliably released into the protected compartment where the fire is occurring.

[0035] (Effect of fire compartment indicator lights) In addition, a fire compartment indicator light is provided on the operation display section of the indoor operation box, and when the fire compartment indicator light is activated by a fire detector, the fire extinguisher corresponding to the protected compartment where the fire is occurring can be opened or the piping opening and closing means can be opened reliably, making it possible to easily and reliably identify the location of the fire inside the building, which is difficult to see from outside, from the outdoor operation box and release the fire extinguishing agent.

[0036] (Effect of using tap water together) In addition, when a fire occurs, the extinguishing agent supply device, such as a fire extinguisher, is opened to release an extinguishing agent, such as a powder fire extinguishing agent or a reinforced liquid fire extinguishing agent, from the extinguishing device into the protected compartment, thereby initially extinguishing the fire. The extinguisher continues to release the extinguishing agent for a short period of time, such as a dozen or so seconds. However, if the fire is not sufficiently suppressed and extinguished, the piping opening and closing means is opened to release tap water from the extinguishing device into the protected compartment, thereby continuing to suppress and extinguish the fire. Since there is no time constraint on the release of tap water, it is possible to reliably extinguish a fire that has been suppressed by the release of the extinguishing agent from the fire extinguisher.

[0037] (Effect of fire extinguishing equipment configuration) In addition, the fire extinguishing equipment comprises a sheet body with multiple outlets provided at various locations on at least one side, and the sheet body is placed in a room or the like that serves as a protected compartment, with multiple outlets arranged in various locations on one side facing the protected compartment, and when a fire occurs, the extinguishing agent is released from the multiple outlets, thereby achieving surface release, which can ensure a wider release range than the point release of conventional sprinkler beds, which release the agent at the installation location, and by reducing the number of areas that are obstructed by water spraying, it is possible to suppress and extinguish a fire with a small amount of extinguishing agent released.

[0038] Here, "area release" refers to multiple release ports (release points) arranged at various locations on the sheet surface, thereby releasing the extinguishing agent over a surface area from multiple locations, i.e., the extinguishing agent is released from the release ports arranged at various locations on the sheet surface, thereby releasing the extinguishing agent over a wide area of ​​the sheet surface. "Point release" refers to the release of the extinguishing agent from a single point, due to the presence of a release port (release point) at one location (installation location). "Line release" refers to the linear release of extinguishing agent from multiple release ports arranged in a straight line.

[0039] In addition, the sheet body is sized to correspond to the size of openings in the protected area, such as doors, walls, and ceiling surfaces, and by reducing the amount of extinguishing agent discharged from each individual outlet, it is possible to discharge a smaller amount of extinguishing agent overall than the amount of water sprayed from a sprinkler head, and with relatively little pressure, to every corner of the target space, making it possible to efficiently suppress and extinguish fires within a specified area in a short period of time, with little impact on the outside, and furthermore, the disaster prevention device can be made lightweight and simple.

[0040] Furthermore, if the sheet body is deployed from above to below (deployed along the side of the protected area) and used as a discharge port that mainly discharges extinguishing agent in a direction perpendicular to the sheet surface, the extinguishing agent will be discharged sideways (from the side of the protected area, for example a room, into the room), allowing the extinguishing agent to reach positions that are hidden from above, such as under tables or desks placed in the room, etc., thereby ensuring the suppression and extinguishing of fires.

[0041] Here, "fire suppression and extinguishing" refers to a combination of the concept of suppressing a fire and another concept of extinguishing a fire. For example, fire suppression is the concept of suppressing the spread of a fire, the burning speed of a fire, or the scale of a fire, while fire extinguishing is the concept of putting out the fire. Of course, it also includes cases where only one of these is done.

[0042] (Effect of sheet deployment in the event of a fire) In addition, since the sheet body equipped with the extinguishing agent flow path and discharge outlet is flexible, under normal circumstances, for example, the sheet body is placed in a non-deployed state, for example in a rolled-up state, at the upper part of the wall surface of the room at a specified position at the boundary of the protected area, thereby requiring less installation space.

[0043] In addition, when a fire occurs, by releasing the sheet body, one end edge of the sheet body, which has one fixed end edge, falls downward while the other end edge of the sheet body unfolds from above to below, and extinguishing agent is released from outlets located in various places on the unfolded sheet body, making it possible to suppress the fire by extinguishing it.

[0044] (Effect of sheet deployment action due to supply of extinguishing agent) In addition, the sheet body can be released from its undeployed state and deployed using the flow pressure of the extinguishing agent supplied in the event of a fire as a driving source. Also, since no electrical release operation is required, the sheet body can be deployed reliably and the extinguishing agent can be discharged even in the event of a power outage.

[0045] (Effect of fixed installation of deployment sheet body) In addition, the sheet body may be placed on the wall of a room to be protected from the start in an expanded (spread out) state, and in the event of a fire, extinguishing agent can be released from multiple outlets located in various places on the sheet body to suppress the fire.

[0046] (Effect of Sheet Structure 1) In addition, by arranging a collapsible and deformable sheet piping with an extinguishing agent supply inlet and discharge outlet between two cover sheets (first cover sheet and second cover sheet), a flexible sheet body with an extinguishing agent flow path and a discharge outlet can be produced simply, easily and at low cost.

[0047] (Effect of Sheet Structure 2) Furthermore, since the first cover sheet body, the first waterproof sheet, the second waterproof sheet and the second cover sheet can be sewn together in a stacked state to form an extinguishing agent flow path with an extinguishing agent supply port and a release port, the formation of the extinguishing agent flow path and the integration of the stacked sheet bodies are achieved simultaneously by sewing, making it possible to more simply and easily create a flexible sheet body with an extinguishing agent flow path and a release port, and since mass production is also easy, manufacturing costs can be further reduced.

[0048] In addition, the extinguishing agent flow path can be simply and easily formed into any desired path pattern by, for example, sewing with a sewing machine or bonding with an adhesive.

[0049] (Cover sheet effect) In addition, the cover sheets (first cover sheet, second cover sheet) have fire prevention, fire resistance, heat resistance, heat insulation, flame insulation, or smoke insulation properties, so they can continue to release fire extinguishing agent without being burned even when exposed to heat or flames from a fire, and when they are installed and deployed at openings such as entrances and exits that form the boundary of a protected area, they can prevent the spread of fire and ensure an escape route by providing flame, heat, and smoke insulation to the outside of the protected area. In addition, the flexibility of the cloth-like body makes it possible to evacuate from inside the protected area to the outside even after the sheet is deployed.

[0050] (Effect of wetting the sheet with fire extinguishing agent) In addition, when creating a fire extinguishing agent flow path by sewing or adhesive, for example, the fire extinguishing agent can be caused to flow outside the fire extinguishing agent flow path as a coolant to wet the sheet body, thereby improving the flame resistance, smoke resistance, and heat resistance of the sheet body.

[0051] (Effect of Extinguishing Agent Flow Path Arrangement on Row of Discharge Ports) In addition, by supplying extinguishing agent from both ends of a discharge port array element in which multiple discharge ports are arranged along the horizontal direction of the sheet body, for example, it is possible to make the discharge pressure of the multiple discharge ports approximately uniform, and to align the discharge pattern (angular distribution) and discharge amount of the extinguishing agent.

[0052] (Effect of the location of fire extinguishing equipment) In addition, the fire extinguishing equipment can be simply and easily installed and used in any position as needed, such as a room entrance / exit, wall, window, or ceiling surface, which is the boundary of the protected area, by positioning the sheet surface along the boundary surface of the boundary when the sheet is in an unfolded state or in an unfolded state, making it possible to install an optimal fire extinguishing equipment that is suited to the usage of the room.

[0053] (Effect of pressure buffering measures) In addition, when the extinguisher is opened to supply the extinguishant to the extinguishant flow path, the accumulated pressure of the extinguisher is high, for example, 0.7 MPa to 0.98 MPa, and if high-pressure extinguishant is added to the extinguisher flow path of the fire extinguisher when the extinguisher is opened, there is a possibility of damage, etc. Therefore, by providing a pressure buffering means such as a tank or an orifice on the extinguisher piping or extinguisher supply port, the increase (or increase rate) of the extinguisher supply pressure from the extinguisher is kept below a predetermined value, thereby preventing damage to the extinguisher flow path and the discharge port. In addition, by providing a buffer area (buffer area) as a second pressure buffering means on the inlet side of the extinguisher flow path of the sheet body, the increase (or increase rate) of the extinguisher supply pressure from the extinguisher is similarly kept below a predetermined value, thereby preventing damage to the extinguisher flow path and the discharge port.

[0054] (Effect of other fire extinguishing equipment) In addition, even in a residential surface discharge type fire extinguishing system that is connected to a specific facility's water supply, or a fire extinguishing system known as a packaged type automatic fire extinguishing system, by providing a fire extinguishing device equipped with a sheet body that is installed in each protected compartment inside the building and has multiple discharge ports that discharge extinguishing agent in various locations on at least one side, the same effect can be obtained as with the fire extinguishing device equipped with a sheet body described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0056] [Fire extinguishing equipment embodiment] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a fire extinguishing system according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment.

[0057] [Basic Concept of the Embodiment] The embodiment generally relates to a fire extinguishing system. The term "fire extinguishing system" refers to a system for suppressing and extinguishing a fire by using a fire extinguishing tool, and is a concept including, for example, a system for activating a fire extinguishing tool by human fire extinguishing activities, and a system for detecting a fire by a fire detection system having a sensor connected to a receiver and automatically activating a fire extinguishing tool.

[0058] The fire extinguishing system includes a fire extinguishing device and a fire extinguishing agent supplying device. The "fire extinguishing device" is installed in a protected area inside a building and releases a fire extinguishing agent to suppress and extinguish a fire. Here, the "protected area" refers to an internal area of ​​a building where the fire extinguishing device is installed, and the internal area of ​​a building is a concept that includes, for example, rooms, corridors, stairs, etc. of the building.

[0059] Further, the term "extinguishing agent supplying device" refers to a device that is installed outside a building, is connected to a fire extinguishing appliance via an extinguishing agent piping, and serves as a source for supplying an extinguishing agent to the fire extinguishing appliance, and is a concept that includes, for example, a fire extinguisher that supplies a powder fire extinguishing agent, a liquid fire extinguishing agent, or the like as an extinguishing agent, a water supply piping that supplies tap water, etc. Here, the term "extinguishing agent piping" refers to a piping that supplies an extinguishing agent to the fire extinguishing appliance, and is a concept that includes, for example, a piping or hose that supplies an extinguishing agent to the fire extinguishing appliance.

[0060] The extinguishant supplying device is stored in an outdoor operation box that is installed outside the building and can be opened and closed. Here, the "indoor operation box" is a container that stores an extinguishant supplying device such as a fire extinguisher, and when a fire breaks out, a user operates the stored extinguishant supplying device to open the device, thereby supplying extinguishant to a protected compartment inside the building where the fire has broken out, and releasing the extinguishant from the extinguisher into the protected compartment to suppress and extinguish the fire. For this reason, the outdoor operation box is provided with a connection port for detachably connecting the extinguishant supplying device, for example, a fire extinguisher, and an operation display unit that shows the correspondence between the fire extinguisher connected to the connection port and the protected compartment inside the building.

[0061] In addition, the outdoor operation box is provided with a fire compartment indicator light as necessary. Here, the "fire compartment indicator light" is an indicator light that indicates the protected compartment in which a fire has occurred based on the detection output of a fire detector provided in the protected compartment. In addition, the outdoor operation box is provided with a release compartment indicator light as necessary. Here, the "release compartment indicator light" is an indicator light that indicates the protected compartment in which extinguishing agent has been released based on the detection output of an operation detector provided in the fire extinguisher.

[0062] In addition, the fire extinguishing system of the embodiment supplies and discharges an extinguishing agent from an extinguishant supplying device or tap water from a water supply pipe to the fire extinguishing device. For example, when a fire occurs, the extinguishing agent from the extinguishant supplying device is supplied to the fire extinguishing device and discharged, and when the discharge of the extinguishing agent from the extinguishant supplying device is completed, it is possible to switch to discharging tap water.

[0063] The fire extinguisher according to the embodiment includes a sheet body, an extinguishing agent flow path, an extinguishing agent supply port, and a discharge port. The "sheet body" is, for example, a flexible, thin, wide body, and is a concept including, for example, a cloth-like body that can be held in a non-deployed state and that can be released from the non-deployed state to be in a deployed state.

[0064] The term "extinguishing agent flow path" refers to a path through which the extinguishing agent flows, which is provided on the sheet body, and is a concept including, for example, a sheet pipe disposed between the cloth bodies. Note that the "sheet pipe" refers to, for example, a flexible pipe that can be crushed and deformed and expands when the extinguishing agent flows through it.

[0065] The term "extinguishing agent supply port" refers to an inlet for supplying an extinguishing agent to an extinguishing agent flow path provided in the sheet body, and is a concept that includes, for example, a connection port for an extinguishing agent pipe.

[0066] In addition, the "discharge port" is an exit port for the extinguishing agent supplied from the extinguishing agent supply port to the extinguishing agent distribution path, and discharges the extinguishing agent from various locations on at least one side of the sheet body, for example, an opening that discharges the extinguishing agent from multiple discharge ports arranged at various locations on one side of the sheet body in the event of a fire.

[0067] The fire extinguisher also includes a sheet deployment means. Here, the "sheet deployment means" refers to a means for normally holding a sheet body in an undeployed state at a predetermined position on the boundary of a protected compartment, and releasing and deploying the sheet body when a fire breaks out. For example, normally, the sheet body is held in a rolled-up, undeployed state at an opening on the boundary of a protected compartment, for example, on the upper ceiling side of an entrance to a room, and when a fire breaks out, the sheet body is released and deployed, with one end edge (upper end edge) fixed and the other end edge (lower end edge) dropping under its own weight and deploying downward to close the opening.

[0068] In the following description, specific details of an embodiment of a fire extinguishing system will be described for a case where the "protected area" is a "room in a building" and the "fire extinguishing agent supply device" is a "fire extinguisher" and / or "water piping."

[0070] [a. Overview of fire extinguishing equipment] As shown in FIG. 1, the fire extinguishing system of this embodiment is intended for a house 11, which is, for example, a detached building, and is composed of a fire extinguishing appliance 12, an extinguishing agent piping 16, and a fire extinguisher 20 that functions as an extinguishing agent supply appliance.

[0071] The fire extinguishing apparatus 12 is installed in each of the protection compartments 10 (10-1) to 10 (10-4) divided into rooms, for example, in the house 11. The fire extinguishing apparatus 12 releases the extinguishing agent supplied from the fire extinguisher 20 into the protection compartments 10 (10-1) to 10 (10-4) to suppress and extinguish a fire. The function and configuration of the fire extinguishing apparatus 12 are arbitrary, but as an example, the fire extinguishing apparatus 12 is composed of a sheet body 14, a holder 15 equipped with a sheet deployment means, and a fire extinguishing agent pipe 16.

[0072] An outdoor operation box 18 is installed at a predetermined location outside the house 11. 18The fire extinguisher 20 is stored in the fire extinguisher 20, and the fire extinguisher 20 is opened (opened) when a fire occurs. The function and configuration of the fire extinguisher 20 are arbitrary, but as an example, a number of fire extinguisher connectors 22 corresponding to the number of protective compartments 10 (10-1) to 10 (10-4) are provided, and the fire extinguishers 20 are detachably connected to the fire extinguisher connectors 22. One end of the fire extinguisher pipes 16 is connected to each of the fire extinguisher connectors 22, and the other end of the fire extinguisher pipes 16 is connected to the fire extinguishers installed in each of the protective compartments 10 (10-1) to 10 (10-4). 12 is connected to

[0073] [b. Installation of fire extinguishing equipment] Next, the installation of the fire extinguishing device in the protected area will be described in detail. As shown in FIG. 2, in a room that is a protected area 10 (10-1), for example, a fire extinguishing device 12 is installed on the ceiling side above a window that is the boundary of the protected area 10 (10-1). The fire extinguishing device 12 is normally held by a holder 15 in a non-expanded state in which a sheet body 14 made of a flexible cloth is wound, for example, in a roll shape. The sheet body 14 is provided with a fire extinguishing agent flow path, and a plurality of discharge ports are provided at various locations on one side of the sheet relative to the fire extinguishing agent flow path. Here, for the protected area 10 (10-1) in FIG. 2, as shown in the figure, the vertical direction with the ceiling surface of the room as the upper side is called the vertical direction or height direction, the direction connecting the left and right wall surfaces as viewed from a window (opening) that is the boundary of the room perpendicular to the vertical direction is called the horizontal direction or left and right direction, and the direction from the window toward the inside of the room is called the depth direction.

[0074] [c. Operation of fire extinguishing equipment] The operation of the fire extinguishing equipment when a fire breaks out will be described in detail. As shown in FIG. 3, for example, a fire shown as a fire source 26 breaks out in a room that is to be a protected compartment 10 (10-1). A user (resident) who notices the fire performs initial fire extinguishing, but if the situation makes it difficult to extinguish the fire, the user quickly evacuates from the house 11 to the outside and heads to an outdoor fire extinguishing box 20 installed in a predetermined place outside the house 11. The user opens the cover of the outdoor operation box 18, checks the fire extinguisher 20 corresponding to the protected compartment 10 (10-1) where the fire has broken out, and performs an opening operation by removing the safety pin of the fire extinguisher 20 and squeezing the lever, whereby the extinguishing agent is supplied through the extinguishing agent piping 16 to the fire extinguishing device 12 installed in the protected compartment 10 (10-1).

[0075] When the fire extinguishing apparatus 12 receives the extinguishing agent from the fire extinguisher 20, the pressure of the extinguishing agent causes the holder 15 to release the sheet body 14, and one end edge of the sheet body 14 is deployed from above to below (vertically) so as to block the window side of the protected compartment 10 (10-1). At the same time, the extinguishing agent is supplied to the extinguishing agent distribution path of the sheet body 14, and the extinguishing agent is released into the protected compartment 10 (10-1) from multiple release ports 24, which are diagrammatically indicated by triangles, thereby suppressing and extinguishing the fire.

[0076] As shown in Fig. 4, if the height direction (up and down direction) of the deployed sheet body 14 is defined as the vertical direction and the direction perpendicular to the vertical direction is defined as the horizontal direction, then, for example, 3 vertical x 3 horizontal discharge ports 24 are arranged on one side of the sheet, and extinguishing agent is discharged from each discharge port 24 in the depth direction into the protected compartment 10 (10-1) to suppress and extinguish the fire. At this time, the extinguishing agent is dispersed from the side into the protected compartment 10 (10-1).

[0077] The discharge distance from the discharge ports 24 arranged in, for example, three tiers in the vertical direction (up-down direction) of the sheet body 14 is such that the higher the position of the discharge port 24, the farther the discharge reaches, covering substantially the entire area on the floor side of the protected compartment 10 (10-1) as a discharge range. Also, if a piece of furniture such as a table is placed in the protected compartment 10 (10-1), the extinguishing agent discharged from the discharge ports 24 of the deployed sheet body 14 will reach the underside of the furniture such as the table. Note that, if it is desired to discharge the extinguishing agent onto the ceiling surface, a portion of the topmost discharge port 24 may be directed upward to discharge onto the ceiling surface to prevent the fire from spreading.

[0078] The extinguishing agent is released from the multiple discharge ports 24 located in various parts of the unfolded sheet body 14 in an overall area-wide manner. Unlike conventional point-type release where a sprinkler head is installed on a ceiling surface, this type of release covers a wide range (scattering range) even with the same amount of release, and the extinguishing agent can reach positions that are hidden from above, such as under tables and desks. As a result, it is possible to suppress and extinguish a fire with a smaller amount of extinguishing agent released.

[0079] [d.Outdoor operation box] (d1. Structure of outdoor operation box) The outdoor operation box 18 installed outside the house will be described in detail. The outdoor operation box 18 stores a fire extinguisher 20, and when a fire occurs, the fire extinguisher 20 is opened to release extinguishing agent from the fire extinguishing device 12 installed in the protected compartment where the fire is occurring. The function and structure of the outdoor operation box 18 are arbitrary, but for example, as shown in Fig. 5, the outdoor operation box 18 is composed of a main body 28 and a cover 30. Here, as shown in the figure, the up-down direction along the exterior wall of the building is referred to as the vertical direction or height direction, the direction along the exterior wall of the building perpendicular to the up-down direction is referred to as the horizontal direction or left-right direction, and the direction toward the exterior wall of the building is referred to as the depth direction.

[0080] (Controlled by remote control device) The main body 28 holds the fire extinguisher 20. Fire extinguisher holder 54The size of the container is sufficient in length, width and depth to store the fire extinguisher 20 and also to open it while it is stored. The container has a diagonal opening at the upper front part of the main body 28, and this opening has a lid 30 that can be opened and closed freely from the top using hinges 32 on the upper edge of the opening. Handles 34 are provided in two places on the bottom side of the lid 30, allowing the user to easily open it to the upward open position shown by lid 30'.

[0081] outdoor operation box 18 As shown in Fig. 6, inside the main body 28, the number of fire extinguisher connecting parts 22 corresponding to the number of protected compartments are provided, and the fire extinguishers 20 are detachably connected to the fire extinguishers 20. 18 An operation display unit 48 is provided on the rear surface of the device, which is exposed when the lid 30 is open.

[0082] The operation display unit 48 shows a room layout (plan view) showing the protected compartments 10 (10-1) to 10 (10-4) of the house 11 shown in FIG. 1, and for example, the protected compartments 10 (10-1) to 10 (10-4) are shown with numbers 1 to 4 in circles. Also, number plates 37 of "1" to "4" are arranged on the fire extinguisher connection part 22 corresponding to the numbers 1 to 4 of the protected compartments. Furthermore, four arrow markers 49 are arranged to indicate the correspondence between the numbers 1 to 4 of the protected compartments on the operation display unit 48 and the fire extinguisher connection part 22 located below them. Therefore, the correspondence between the protected compartments 10 (10-1) to 10 (10-4) and the fire extinguisher connection part 22 can be simply and easily understood, and the fire extinguisher 20 corresponding to the protected compartment where a fire has occurred can be easily identified and opened.

[0083] The fire extinguisher 20 is opened by removing the safety pin 52 and pushing down the lever 50. At this time, even if the user is unfamiliar with the operation of the fire extinguisher 20, since the fire extinguisher 20 is stored in the outdoor operation box 18 outside the house and is away from the inside of the house where the fire is occurring, the user can calmly operate the extinguisher 20 without panicking, and can open the fire extinguisher 20 quickly and reliably.

[0084] Here, an outdoor light is provided for the outdoor operation box 18 installed in a specified location outside the house 11, to illuminate the installation location, so that the outdoor operation box 18 can be operated even in the event of a fire at night. Also, lighting may be provided inside the body 28 of the indoor operation box 18 or on the back side of the lid 30, so that the lighting is turned on when the lid 30 is opened.

[0085] (d2. Fire extinguisher connection part) The fire extinguisher connector 22 provided on the outdoor operation box 18 will now be described in detail. The fire extinguisher connector 22 is for detachably connecting the fire extinguisher 20, and while its function and configuration are arbitrary, for example, as shown in FIG. 7, it is composed of a fire extinguisher nozzle 36 and a fire extinguisher connection port 38. The fire extinguisher nozzle 36 is a separately prepared nozzle that is removed from the tip of the fire extinguisher hose 40 and attached thereto. The fire extinguisher connection port 38 is attached to a partition plate inside the main body 28. 29 and one end of the extinguishing agent pipe 16 is connected thereto.

[0086] The fire extinguisher connection port 38 is provided with a nipple 42 with an O-ring attached at the tip, and is connected and fixed by fitting the opening of the fire extinguisher nozzle 36 into the nipple 42. The fire extinguisher nozzle 36 is a slider. 44 A slider 44 By sliding in the direction of the arrow in the figure, the fire extinguisher nozzle 36 connected to the fire extinguisher connection port 38 can be removed.

[0087] (d3. Number of fire extinguishers stored) As shown in the piping configuration of Fig. 8(A), the fire extinguisher hose 40 of the fire extinguisher 20 is basically connected to all of the fire extinguisher connectors 22 for the fire extinguishers 20 provided in the outdoor operation box 18. Also, as shown in Fig. 8(B), for example, two fire extinguishers 20, which is fewer than the number of fire extinguisher connectors 22, may be stored in the outdoor operation box 18, and in the normal state, as in the case of the right-side fire extinguisher 20, the fire extinguisher nozzle 40 may be connected to the fire extinguisher connection port 38 of the fire extinguisher connector 22. 36In the event of a fire, as with the fire extinguisher 20 on the left, the fire extinguisher nozzle 36 can be connected to the fire extinguisher connection port 38 of the fire extinguisher connection part 22 corresponding to the protected compartment where the fire has occurred and opened. This allows the number of fire extinguishers 20 that are always stored in the outdoor operation box 18 to be reduced, and the maintenance costs to be reduced.

[0088] In addition, the extinguisher 20 releases the extinguishing agent for a short period of time, such as a dozen or so seconds. If the fire is not extinguished even after the fire extinguisher 20 has been used up, the extinguisher nozzle 36 can be removed from the fire extinguisher connection port 38 of the fire extinguisher connection part 22 and the extinguisher nozzle 36 of an unused fire extinguisher 20 can be connected to continue releasing the extinguishant, thereby enabling reliable suppression and extinguishing of the fire.

[0089] In addition, when a fire occurs in the vicinity of the house 11 in which the fire extinguishing equipment is installed, the fire extinguisher 20 stored in the outdoor operation box 18 can be taken out and used, so that the system can also be used for local disaster prevention.

[0090] [e. Other embodiments of the outdoor operation box] Next, another embodiment of the outdoor operation box will be described in detail. Fig. 9 shows the other embodiment of the outdoor operation box, and Fig. 10 shows the piping configuration.

[0091] The outdoor operation box 18 of this embodiment shares a common extinguisher 20 as an extinguishing agent supply source, provides a selection valve 114 functioning as a pipe opening and closing means on the extinguisher piping 16 provided corresponding to the protected compartment, and opens the selection valve 114 to select the protected compartment where a fire has occurred and operate the fire extinguisher 20. The outdoor operation box 18 may have any function or configuration, but for example, a collective pipe 35 is provided between the extinguisher piping 16 side and the fire extinguisher 20 side. Here, the "collective pipe 35" means a pipe having a function of collecting and connecting a plurality of fire extinguishers 20 in one place, and of dividing and connecting the fire extinguishers 20 collected in one place to a plurality of extinguisher piping 16.

[0092] 1 is connected to the other end of the extinguishant pipe 16 via a selection valve 114. The extinguisher nozzle 36 provided at the tip of the fire extinguisher hose 40 of the fire extinguisher 20 is connected to the extinguisher pipe 35 via the selection valve 114. The extinguisher pipe 35 is provided with, for example, two fire extinguisher connection ports 38, and these are connected to the extinguisher nozzle 36 provided at the tip of the fire extinguisher hose 40 of the fire extinguisher 20, forming a detachable fire extinguisher connection part 22. The other configuration is the same as that of the embodiment in FIG.

[0093] In the outdoor operation box 18 of this embodiment, when a fire occurs, the user uses the operation display unit 48 to check and open the selection valve 114 corresponding to the protected compartment where the fire has occurred, and then opens one of the two fire extinguishers 20 to supply extinguishing agent to the protected compartment where the fire has occurred.As shown in Figure 4, the sheet body 14 is unfolded to spray the extinguishing agent into the protected compartment from the discharge port 24.

[0094] Here, if the fire is not sufficiently suppressed and extinguished even after the discharge of extinguishing agent from the opened fire extinguisher 20 has ended, the discharge of extinguishing agent can be easily continued by opening the next fire extinguisher 20, without the need to remove the used fire extinguisher 20 and connect an unused fire extinguisher 20 in the outdoor operation box 18 shown in Fig. 8. In other words, by sharing the multiple fire extinguishers 20 stored in the outdoor operation box 18 as a fire extinguisher supply source, it is possible to more reliably suppress and extinguish the fire by continuously discharging the extinguishant equivalent to the number of fire extinguishers 20.

[0095] In addition, the number of fire extinguishers 20 stored in the outdoor fire box 18 in this embodiment is, for example, two, which is less than the number of protected compartments, which is, for example, four compartments. Compared to the case where a fire extinguisher is provided for each protected compartment, the number of fire extinguishers stored can be reduced, thereby reducing the cost of maintaining the fire extinguishers.

[0096] [f. Outdoor operation box equipped with fire compartment indicator light and operating compartment indicator light] Next, an embodiment of an outdoor operation box equipped with a fire compartment indicator light and an operation compartment indicator light will be described in detail. As shown in Fig. 11, the outdoor operation box 18 of this embodiment is further provided with a fire compartment indicator light 45 and a discharge compartment indicator light 46 corresponding to the fire extinguisher connection part 22 in addition to the outdoor operation box 18 shown in Fig. 6. The other configurations are the same as those of the embodiment in Fig. 4.

[0097] (f1. Fire compartment indicator light) The fire compartment indicator light 45 indicates the protected compartment in which a fire has occurred based on the detection output of a fire detector that detects a fire in the protected compartment, and its function and configuration are arbitrary, but for example, an indicator light using a red LED may be provided.

[0098] In addition, as shown in FIG. 12, in correspondence with the fire compartment indicator light 45 provided on the outdoor operation box 18, for example, a wireless-linked fire alarm 116 that functions as a fire detector is provided in the rooms that become the protected compartments 10 (10-1) to 10 (10-4) of the house 11. When the fire alarm 116 detects a fire, it outputs a fire alarm by sound and light, and also wirelessly transmits a fire-linked signal including a preset unique address, so that other fire alarms 116 output fire alarms in a linked manner. The outdoor operation box 18 is provided with a reception control unit 118. The reception control unit 118 identifies the protected compartment in which the fire was detected based on the address included in the fire-linked signal received from the fire alarm 116, and turns on or blinks the corresponding fire compartment indicator light 45 provided on the outdoor operation box 18 in FIG. 11. The fire alarm 116 installed in the protected compartment may be of a wired type that is connected to the reception control unit 118 by a signal line.

[0099] In this manner, in the outdoor operation box 18 of this embodiment, when a fire occurs, the fire compartment indicator light 120 lights up or flashes, allowing the user to know the protected compartment where the fire is occurring inside the house, which is difficult to see from outside, and to reliably open the corresponding fire extinguisher 20.

[0100] (f2. Discharge area indicator light) The discharge compartment indicator light 46 indicates the protected compartment in which the fire extinguisher 12 is operating and discharging extinguishing agent, and may have any function or configuration, but may be, for example, an indicator light using a green LED.

[0101] 12, the fire extinguishers 12 arranged in the protected compartments 10 (10-1) to 10 (10-4) are provided with operation detectors 100 corresponding to the discharge compartment indicator lights 46 provided on the outdoor operation box 18, and are connected to the receiving control unit 118. The operation detectors 100 detect the operation of discharging extinguishant from the fire extinguishers 12, and may have any function or configuration. For example, a detection switch or the like is provided that detects the deployment of the sheet body 14 when the fire extinguisher 12 is supplied with extinguishant and outputs a detection signal. When the receiving control unit 118 receives a detection signal indicating the discharge of extinguishant from the fire extinguisher 12 from the operation detector 100, it lights or flashes the discharge compartment indicator light 46 of the corresponding protected compartment.

[0102] In this manner, in the outdoor operation box 18 of this embodiment, when the fire extinguisher 20 is opened, the discharge compartment indicator light 46 lights up or flashes, and the fire extinguishing device of the protected compartment where a fire has broken out in the house is indicated. 12 It is easy to check at the outdoor operation box 18 that the fire extinguishing agent is being discharged.

[0103] [g. Fire extinguishing equipment that also uses tap water] Next, an embodiment of a fire extinguishing system that uses both the extinguishing agent from the fire extinguisher and tap water from the water pipe will be described in detail. In the fire extinguishing system of this embodiment, the installation of the fire extinguishing device 12 and the connection of the fire extinguishing pipe 16 to the protected compartments 10 (10-1) to 10 (10-4) of the house 11 are the same as in the embodiment of Fig. 1, and the configuration of the outdoor operation box 18 is the same as that of the outdoor operation box 18 in Fig. 9, for example. In addition, a water pipe 122 is connected to the collecting pipe 35 of the outdoor operation box 18. 122 Branch and connect the branched water supply Concatenation An opening / closing valve 124 functioning as a first pipe opening / closing means is provided at a position on the pipe 126 inside the outdoor operation box 18 .

[0104] In addition, water supply Concatenation Corresponding to the connection of pipe 126, water supply Concatenation A check valve 128, for example, functioning as a second pipe opening / closing means is provided in the pipe between the collective pipe 35 to which the pipe 126 is connected and the extinguishing agent connection port 38 of the fire extinguisher connection part 22. The check valve 128 prevents tap water from flowing out even when the fire extinguisher 20 side is removed from the fire extinguisher connection part 22 in a state in which tap water is supplied to the collective pipe 35 by operating the on-off valve 124 to the open state. Note that when the fire extinguisher 20 side is removed, tap water will not flow out if the on-off valve 124 is operated to the closed state, so the check valve 128 does not necessarily have to be provided.

[0105] In the fire extinguishing system of this embodiment, when a fire breaks out, the user opens the selection valve 114 corresponding to the protected compartment where the fire breaks out, and then opens the fire extinguisher 20 to supply and release an extinguishing agent, such as a powder extinguishing agent, to the fire extinguisher 12, but the duration of the release of the extinguishing agent by the fire extinguisher 20 is short, such as a dozen seconds, and if the fire is not sufficiently suppressed and extinguished, the on-off valve 124 is operated to an open state, and tap water is supplied to the fire extinguisher 12 to be released into the protected compartment. Since there is no time constraint on the release of tap water, the fire suppressed by the release of the extinguisher 20 can be reliably suppressed and extinguished by the subsequent release of tap water.

[0106] [h. Residential surface discharge type fire extinguishing equipment connected to tap water for specific facilities] Next, an embodiment of a fire extinguishing system that discharges only tap water as a fire extinguishing agent will be described in detail. Conventional residential fire extinguishing systems that discharge tap water from a sprinkler head are known as "specific facility tap water connected residential point discharge type fire extinguishing systems," whereas this embodiment is a fire extinguishing system that discharges tap water from multiple discharge ports arranged at various locations on one side of a sheet body that is deployed when a fire occurs, and therefore can be called a "specific facility tap water connected residential surface discharge type fire extinguishing system."

[0107] In the embodiment of the fire extinguishing equipment that discharges tap water on a surface, as shown in FIG. 14, a fire extinguishing apparatus 12 having a sheet body with a plurality of discharge ports at least on one side is installed in each room, which is the protected compartments 10 (10-1) to 10 (10-4) of a house 11, and one end of a fire extinguishing agent pipe 16 connected to the fire extinguishing apparatuses 10 (10-1) to 10 (10-4) at the other end is connected via a selection valve 114 to a collective pipe 35 of an outdoor operation box 18 installed outside the house 11. Furthermore, a water pipe branched from a water pipe 122 is connected to the collective pipe 35. Concatenation A pipe 126 is connected via an on-off valve 124 that functions as a pipe opening and closing means. The on-off valve 124 is always in an open state.

[0108] The specific configuration of the outdoor operation box 18 of this embodiment is similar to that of the outdoor operation box 18 shown in FIG. 6, FIG. 9, or FIG. 11, except that the extinguishant supply system on the fire extinguisher 20 side is removed.

[0109] According to this embodiment, when a fire occurs, the selection valve 114 corresponding to the protected compartment where the fire has occurred is opened, so that tap water is supplied to the fire extinguishing device 12 installed in the protected compartment where the fire has occurred via the fire extinguishing agent piping 16, and as shown in FIG. 4, the sheet body 14 is unfolded and the tap water is discharged from the discharge ports 24 arranged in various places to suppress and extinguish the fire.

[0110] [i. Packaged automatic fire extinguishing equipment] Next, an embodiment of a fire extinguishing system that functions as a packaged automatic fire extinguishing system, that is, a so-called surface discharge type fire extinguishing system for residential use, will be described in detail.

[0111] In the fire extinguishing system of this embodiment, a fire extinguishing device 12 is installed in each of the rooms, which are the protected areas 10 (10-1) to 10 (10-4) of a house 11, and in the event of a fire, a sheet body is deployed to release a fire extinguishing agent from multiple outlets provided in various locations on one side. In addition, a fire detector, for example, a wireless-linked fire alarm 116 is installed.

[0112] In addition, a package storage box 18a corresponding to the outdoor operation box is provided to supply and release extinguishing agent to the fire extinguisher 12 in the event of a fire. The package storage box 18a is provided with a plurality of extinguishing agent storage containers 130, pressurized gas containers 132 filled with starting gas, a starting valve 134, a pressure adjusting valve 136, a remote selection valve 138 for each extinguishing agent pipe 16, and a receiving control unit 140.

[0113] In this embodiment, if a fire breaks out in the protected section 10 (10-1), for example, the fire alarm 116 detects the fire and issues an alarm, while also transmitting a fire interlocking signal including a unique address, which is received by the reception control unit 140 of the package storage box 18a. The reception control unit 140 detects the protected section 10 (10-1) in which the fire is occurring based on the address included in the received fire interlocking signal, and controls the remote selection valve 138 corresponding to the detected protected section 10 (10-1) to an open state, and also controls the start-up valve 134 to an open state.

[0114] When the start valve 134 is controlled to be in the open state, pressurized gas such as carbon dioxide is supplied from the pressurized gas container 132 to the extinguishing agent storage 130 connected in series with the piping, the stored extinguishing agent is discharged, and after being adjusted to a predetermined pressure by the pressure regulating valve 136, the extinguishing agent is supplied from the collecting piping 35 to the fire extinguishing equipment 12 in the protected compartment 10 (10-1) via the extinguishing agent piping 16 equipped with a remote selection valve 138 in the open state.

[0115] The fire extinguishing equipment 12 in the protected compartment 10 (10-1) that has received the supply of extinguishing agent unfolds the sheet body 14 and releases the extinguishing agent from the discharge ports 24 disposed in various locations, as shown in FIG. 4, to suppress and extinguish the fire.

[0116] [j. Fire extinguishing equipment] Next, the sheet body 14 provided on the fire extinguisher 12 will be described in more detail with reference to Figs.

[0117] (j1. Seat structure) The sheet body 14 of the fire extinguisher 12, when supplied with extinguishing agent, unfolds to separate an opening at the boundary of the protected compartment, for example, an opening at the entrance / exit of a room, and in the unfolded state, discharges the extinguishing agent into the protected compartment, and while the configuration and structure are arbitrary, as an example, as shown in Fig. 16, it is composed of an extinguishing agent flow path 58, an extinguishing agent supply port 56, and a discharge port 24 provided in the sheet body 14 (14a). Here, as shown in the figure, the up-down direction of the sheet body 14 (14a) is referred to as the vertical direction or height direction, and the direction perpendicular to the up-down direction is referred to as the horizontal direction or left-right direction.

[0118] The sheet body 14 (14a) is a rectangular sheet body whose length and width, when deployed, correspond to the size of the opening at the boundary of the protected area, for example, the entrance / exit of a room, and since it is made of a cloth-like material, it is flexible and can be easily undeployed by rolling it up into a roll.

[0119] The extinguishing agent supply port 56 serves as an inlet for the extinguishing agent to the extinguishing agent flow path 58, and may have any configuration or structure. For example, the extinguishing agent supply port 56 is disposed on one end edge (upper end edge) side of the sheet body 14 (14a) with the extinguishing agent inlet facing upward, and serves as an inlet for flowing the extinguishing agent into the extinguishing agent flow path 58 within the sheet body 14, as shown by the dotted line.

[0120] The extinguishing agent distribution path 58 is provided in the sheet body 14 (14a) and distributes the extinguishing agent supplied from the extinguishing agent supply port 56. The configuration, structure and arrangement of the extinguishing agent distribution path 58 are arbitrary. For example, the extinguishing agent distribution path 58 is arranged in the vertical direction (the direction in which the extinguishing agent flows downward) of the sheet body 14 (14a) so as to form a four-stage ladder shape, with the extinguishing agent supply port 56 located in the center of the topmost first stage and the discharge ports 24 located, for example, in three locations each, on the second to fourth stages.

[0121] The discharge ports 24 are arranged at various locations in the extinguishant flow path 58, and discharge the extinguishant supplied from the extinguishant supply port 56 to the extinguishant flow path 58 onto one side of the sheet body 14 (14a). The structure, arrangement and number of the discharge ports 24 are arbitrary, but for example, as described above, they are arranged in three locations each on the second to fourth rows of the extinguishant flow path 58.

[0122] Here, the extinguishing agent flow path 58 laid out to form a four-stage ladder shape is formed to supply extinguishing agent from both ends of each outlet row element to the horizontal row of outlets 24 arranged in the second to fourth stages (each outlet row arranged in the horizontal direction in each stage is regarded as one outlet row element, and the outlet row elements are arranged in three stages from the second to fourth stages to form the entire outlet row). This makes it possible to make the discharge pressure of the extinguishing agent supplied to the multiple outlets 24 in the same row approximately uniform, and to make the discharge pattern (angle distribution) and discharge amount in the same row uniform.

[0123] The shape of the extinguishant flow path 58 for supplying the extinguishant to the multiple discharge ports 24 is not limited to a ladder shape, and may include other suitable shapes such as a tree shape, a tournament shape, etc. In addition, when the discharge pressure of the multiple discharge ports 24 is to be approximately uniform, the thickness (cross-sectional area) of the extinguishant flow path 58 may be made thicker on the extinguishant supply port 56 side and thinner as it moves away from the extinguishant supply port 56.

[0124] (j2. Pressure buffer device) A pressure buffer device 55 functioning as a pressure buffer means is provided at the extinguishing agent supply port 56 of the sheet body 14 (14a).

[0125] When the fire extinguisher 20 is opened to supply extinguishing agent to the sheet body 14 (14a), the accumulated pressure of the fire extinguisher 20 is high, for example, 0.7 MPa to 0.98 MPa, and if high-pressure extinguishing agent is applied to the extinguishant flow path 58 and the discharge port 24 of the sheet body 14 (14a) when the fire extinguisher 20 is opened, there is a possibility that they will be damaged.

[0126] Therefore, a pressure buffer device 55 is provided at the extinguishant supply port 56 which is the inlet of the extinguishant flow path 34. The pressure buffer device 55 keeps the increase (or rate of increase) of the extinguishant supply pressure from the fire extinguisher 20 below a predetermined level in the initial stage after the start of extinguishant supply, and may have any configuration or structure, for example, an orifice, a tank, or the like, to prevent damage to the extinguishant flow path 58 and the discharge port 24. The pressure buffer device 55 may be provided midway along the extinguishant piping 16.

[0127] (j3. Sheet body manufacturing method 1) The sheet body 14 (14a) of this embodiment shown in FIG. 16 is manufactured, for example, by the method shown in FIG. 17. First, a first cover sheet 60 and a second cover sheet 62 of a predetermined size are prepared. The first cover sheet 60 and the second cover sheet 62 are, for example, cloth-like bodies having fireproofing, fire resistance, heat resistance, or flame retardancy, and can be, for example, those called fireproof sheets, fireproof curtains, fireproof screens, etc. that can withstand high heat of 1200°C, but are not limited thereto. In addition, the first cover sheet 60 and the second cover sheet 62 also have heat-shielding, flame-shielding, or smoke-shielding properties, etc. It is not prohibited that only the cover sheet (first cover sheet 60) facing the inside of the protected area has fireproofing, fire resistance, heat resistance, flame retardancy, heat-shielding, or flame-shielding properties.

[0128] Next, for example, a four-stage ladder-shaped sheet piping 64 is prepared here. The sheet piping 64 is made, for example, of a cloth material such as polyester used for lining umbrellas, formed into a pipe shape and connected in a ladder shape (connections are made to be able to flow), and as shown in the cross section of Fig. 18(A), it is freely crushable and deformable, and becomes flat when crushed from the cover sheet side, and when extinguishing agent 68 is supplied, it swells as shown in the cross section of Fig. 18(B), forming the extinguishing agent flow path 58.

[0129] As shown in FIG. 17, the sheet piping 64 is provided with an extinguishing agent supply port 56 equipped with a pressure buffer device 55 and a discharge port 24, and a through hole 66 is formed in the first cover sheet 60 corresponding to the discharge port 24.

[0130] The discharge port 24 has a structure shown in, for example, Figures 19(A), (B), and (C). The discharge port 24 is composed of a base 70 and a clamping ring 72. A screw shaft 74 stands up from the base 70, and a discharge hole 78 passes through the screw shaft 74. The clamping ring 72 has a screw hole 76, and the screw shaft 74 The connector is screwed into place.

[0131] As shown in FIG. 19(A), the base 70 is placed in the sheet pipe 64, and as an example, as shown in FIG. 19(C), the base 70 is bonded and fixed at the bonding portion 82, and the screw shaft 74 The screw shaft 74 is taken out from the opening provided in the sheet pipe 70, passed through a through hole 66 (see FIG. 17) of the first cover sheet 60, and a clamping ring 72 is screwed into the through hole, thereby clamping and fixing the sheet pipe 64 to the back surface of the first cover sheet 60.

[0132] 17, a sheet pipe 64 provided with a discharge port 24 and an extinguishing agent supply port 56 is disposed on the back side of the first cover sheet 60 in the thickness direction of the sheet body 14 (14a), and a second cover sheet 62 is disposed on the opposite side of the first cover sheet 60 with the sheet pipe 64 sandwiched therebetween. 60 16, the sheet body 14 (14a) is completed by sewing the first cover sheet 62 and the second cover sheet 62 together at seams 92 indicated by two-dot chain lines using waterproof thread.

[0133] Here, the discharge hole 78 provided in the base 70 of the discharge port 24 determines the opening diameter of the discharge port 24, and is set to, for example, a hole diameter of about 3 to 4 mm. By discharging the extinguishing agent from a hole diameter of about 3 to 4 mm from a plurality of discharge ports 24 arranged at various positions on the sheet body 14, the extinguishing agent is discharged over a surface as a whole.

[0134] Further, the discharge hole 78 penetrating the screw shaft 74 functions as a nozzle that determines the discharge pattern of the extinguishing agent. For example, the straight discharge hole 78 shown in Fig. 19 has a comparatively narrow-angle discharge pattern, but if the outlet opening of the discharge hole 78 is widened into a cone shape, a wide-angle discharge pattern spreading in a cone shape will be obtained, and an appropriate opening shape is selected according to the required discharge pattern. Discharge ports 24 having different opening shapes may be appropriately mixed.

[0135] In this embodiment, the central axis of the discharge hole 82 (the dashed line in the figure) is perpendicular to the sheet surface, but is not limited to this. For example, the directionality of the extinguishing agent discharge can be adjusted by adjusting the inclination angle of the central axis with respect to the sheet surface.

[0136] Furthermore, a cooling outlet may be provided in the sheet pipe 64 constituting the extinguishing agent flow path 58 as wetting means (cooling means) for wetting and cooling the first cover sheet 60 and the second cover sheet 62, separate from the outlet 24, or a cooling sheet pipe for cooling that constitutes the cooling flow path, either separate from the sheet pipe 64 or branching off from the sheet pipe 64, may be provided and a cooling outlet provided in this. This improves the fire prevention, fire resistance, heat resistance, etc. of the first cover sheet 60 and the second cover sheet 62, and enables the use of sheets of a lower grade for these performances, thereby reducing costs.

[0137] (j4. Seat body with buffer area) FIG. 20 shows another embodiment of a sheet body 14 (14b) used for discharging an extinguishant from a fire extinguisher 20, in which the sheet body 14 (14b) is provided with a buffer area 65 functioning as a second pressure buffer means following the extinguishant supply port 56, and an extinguishant distribution path 34 is provided through the buffer area 65 with discharge ports 24 arranged at various locations.

[0138] The buffer area 65 provided on the inlet side of the extinguishant flow path 58 temporarily retains the extinguishant from the fire extinguisher 20 in the initial stage after the start of the extinguishant supply, thereby keeping the increase (or rate of increase) of the extinguishant supply pressure below a predetermined level, thereby preventing damage to the extinguishant flow path 58 and the discharge port 24. The rest of the configuration is the same as that of the sheet body 14 (14a) in FIG. 5 except for the pressure buffer device 55.

[0139] In addition, the buffer area 65 may be arranged under the sheet body 14 (14b) so as to function as a weight (auxiliary means) when the sheet body 14 (14b) is unfolded.

[0140] (j5. Sheet body manufacturing method 2) Next, a method for producing the sheet body 14 (14c) shown in Fig. 21 will be described. The sheet body 14 (14c) in Fig. 21 is characterized in that the extinguishing agent flow path 58 is formed by the stitching portion 90 shown by the two-dot chain line without using the sheet piping 64 shown in Fig. 17.

[0141] Figure 22 shows a method for producing the sheet body 14 (14c) of Figure 21. First, a first cover sheet 60, a first waterproof sheet 84, a second waterproof sheet 86, and a second cover sheet 62 of a predetermined size are prepared. The first cover sheet 60 and the second cover sheet 62 are the same as those shown in the production method of Figure 17, and the first waterproof sheet 84 and the second waterproof sheet 86 are, like the sheet piping 64 shown in the production method of Figure 17, made of a cloth-like material such as polyester used for lining umbrellas.

[0142] An extinguishing agent supply port 56 equipped with a pressure buffer device 55 is disposed in the center of the upper end of the first waterproof sheet 84 in correspondence with the extinguishing agent flow path 58, and through holes 88, 66 are pre-formed in the first waterproof sheet 84 and the first cover sheet 60 in correspondence with the discharge outlet 24 of the extinguishing agent flow path 58 so as to be in the same position when the sheet 14 (14c) is completed.

[0143] First waterproof sheet 84 and first cover sheet 60 With the through holes 88, 66 aligned and overlapped, the discharge port 24 is attached and fixed as shown in Fig. 23. This discharge port 24 has the same structure as the discharge port 24 shown in Fig. 19, and is composed of a base 70 with a screw shaft 74 standing up, and a clamping ring 72 with a screw hole 78. 74 A discharge hole 82 penetrates through the nozzle.

[0144] With the first waterproof sheet 84 and the first cover sheet 60 fixed by the discharge port 24, as shown in Fig. 22, the second waterproof sheet 86 and the second cover sheet 62 are overlapped on the first waterproof sheet 84 side, and in this state, as shown in Fig. 21, waterproof thread is used to sew together with a sewing machine or the like to form a seam 90, thereby creating the extinguishing agent distribution path 58. Furthermore, with the sheets overlapped, they are integrated into the sheet body 14 by a seam 92 where the periphery of the sheets is sewn together.

[0145] The sheet body 14 (14c) in Fig. 21 thus produced has, as described above, an extinguishing agent flow path 58 formed at a seam 90 sewn by a sewing machine or the like using waterproof thread in a state in which the first cover sheet 60, the first waterproof sheet 84, the second waterproof sheet 86 and the second cover sheet 62 are overlapped. The extinguishing agent flow path 58 is normally in a compressed state as shown in Fig. 24(A), but when extinguishing agent 68 is supplied, it expands to increase its cross-sectional area as shown in Fig. 24(B), allowing the extinguishing agent 68 to flow.

[0146] 21, the seam 90 is doubled (two rows of seams) to improve the airtightness of the extinguishing agent flow path 60, but when tap water is supplied as an extinguishing agent, a small amount of water may leak from the seams. However, the tap water leaking from the extinguishing agent flow path 58 wets the sheet body 14 (14c), thereby improving the fire prevention, fire resistance, heat resistance, heat insulation, flame insulation, and smoke insulation properties against fire.

[0147] In this way, as a wetting means (cooling means) for wetting and cooling the first cover sheet 60 and the second cover sheet 62, a cooling outlet may be provided in the extinguishant flow path 58 formed by the stitching portion 90, in addition to the outlet 24. The cooling outlet may be formed by adjusting the stitching portion 90 forming the extinguishant flow path 58 so that the stitching interval of the stitching line is partially increased, or by skipping stitching in part, to form a gap as the cooling outlet. Also, a flow path provided with a cooling outlet (cooling flow path) may be provided separately from the extinguishant flow path 58.

[0148] [k. Sheet deployment means] Next, a detailed description will be given of the sheet deployment means provided in the fire extinguisher 12. As shown in Figures 25(A) and (B), the fire extinguisher 12 of this embodiment is provided with a sheet deployment means.

[0149] (k1. Seat deployment structure) The sheet deployment means normally holds the sheet 14 in a non-deployed state, and deploys the sheet body 14 in the event of a fire, supplying extinguishing agent to the extinguishing agent distribution path 58 of the deployed sheet body 14 and discharging it from the multiple discharge ports 24.The configuration and structure of the sheet deployment means are arbitrary, but it is composed of, for example, a holder 15, a sheet holding member 96, and a sheet holding release section 98.

[0150] The holder 15 is a box-shaped storage means with the longitudinal direction being the horizontal direction (left-right direction) and constitutes a fixing part that is fixed to an opening in the boundary of a protected area, such as the upper ceiling side of a room entrance / exit or window, etc. One end of the sheet body 14 is fixed to the holder 15, and normally, in a non-deployed state wound up in a roll, it is held in a suspended state at multiple points on the underside of the holder 15 by sheet holding members 96 made of wires or ropes.

[0151] One end of the sheet holding member 96 is fixed to the holder 15, and the other end is passed under the outer periphery of the rolled-up sheet body 14 and is detachably held by a sheet holding release part 98 on the opposite side (opposite the fixed side) of the holder 15. The sheet holding release part 98 operates upon receiving a supply of extinguishing agent from the extinguishing agent piping 16, and releases the holding of the sheet holding member 96.

[0152] (k2. Operation detector) Here, the sheet deployment means of the fire extinguisher 12 used in the fire extinguishing equipment of Figures 11 and 12 is provided with an operation detector 100. As described above, the operation detector 100 detects the operation of releasing the extinguishing agent from the fire extinguisher 12, and while its function and configuration are arbitrary, for example, as shown in Figure 25 (B), a limit switch, for example, is built in to the underside of the holder 15. The limit switch provided as the operation detector 100 turns off the switch contact when the sheet body 14 is held in a rolled, undeployed state, and when the sheet body 14 is released from the hold by the sheet hold release part 98 and deployed, the switch contact turns on, and the fire extinguisher 12 A detection signal indicating the discharge of the extinguishing agent by the sheet deployment means is output to the receiving control unit 118 of the outdoor operation box 18 shown in the embodiment of Fig. 12, which causes the corresponding discharge indicator light 46 to light up or flash. If the outdoor operation box 18 is not provided with a discharge indicator light 46, it is not necessary to provide the operation detector 100 in the sheet deployment means.

[0153] 25(C)(D), with one end edge (upper end edge) of the sheet body 14 fixed to the holder 15, the other end edge (lower end edge when unfolded) on the opposite side falls under its own weight and unfolds from above downward (vertically). If a predetermined weight member is provided on the lower end edge side of the sheet body 14, it is possible to assist in preventing the lower end edge of the sheet body 14 from falling and in stabilizing the sheet body 14 after unfolding.

[0154] (k3. Seat retention release part) The sheet retention release part 98, which releases and deploys the sheet body 14 held in a non-deployed state, will be described in more detail below. The configuration and structure of the sheet retention release part 98 are arbitrary, but as an example, as shown in Fig. 26(A), an actuator 102 that operates when a fire extinguishing agent is supplied is provided inside the holder 15.

[0155] As an example, as shown in FIG. 26B, the actuator 102 is a piston connected to a cylinder 104 via a return spring 108. 104bis incorporated so that it can slide freely, and the piston 104b A cylinder chamber 104a is formed on one side of the cylinder chamber 104. The cylinder chamber 104a communicates with the extinguishing agent piping 16 via an extinguishing agent supply port 107, and is provided with an automatic drain valve 105. The automatic drain valve 105 closes when the extinguishing agent is supplied and the pressure in the cylinder chamber 104a exceeds a predetermined pressure, and opens when the pressure in the cylinder chamber 104a falls below the predetermined pressure.

[0156] piston 104b Holder 15 is provided with a rod 106 coaxially. An opening 112 is provided from the front to the bottom of holder 15, making the tip side of rod 106 visible, and an operating stick 110 provided at a predetermined position on rod 106 is exposed on the front side of holder 15 so as to be operable from the outside.

[0157] When the sheet holding member 96 is held on the rod 106, the operating stick 110 is operated to move the rod 106 to the left, and a retaining ring 96a, which is made of a wire or the like and has a loop-shaped end, is passed through the rod 106 to hold the sheet body 14 wound in a roll.

[0158] In the event of a fire, extinguishing agent is supplied from the extinguishing agent pipe 16 to the cylinder chamber 104a through the extinguishing agent supply port 107, and the piston moves against the return spring 108. 104b The rod 106 comes out of the retaining ring 96a, whose movement to the left is restricted by the lower portion of the opening 112. As a result, the seat body 14 is released from the seat holding member 96, falls under its own weight, and unfolds from above to below.

[0159] It should be noted that other appropriate structures can be applied as the sheet deployment structure of the fire extinguisher 12. For example, the sheet body 14 may be wound around a rotating shaft and deployed by releasing the engagement of the rotating shaft, or the sheet body 14 may be unwound and wound by a motor drive. Also, the sheet body 14 may be held in a bellows-like folded state and deployed by releasing the hold.

[0160] In addition to the ladder-shaped arrangement shown in Figures 16, 20, and 21, the extinguishing agent flow path 58 of the sheet body 14 may be arranged, for example, in a rectangular shape surrounding the periphery of the ladder shape, so that the extinguishing agent flow path 58 functions as a "weight" that assists in the deployment of the sheet body 14 when extinguishing water is supplied as an extinguishing agent and also serves as an auxiliary means for stabilizing the deployed state.

[0161] [l.Fire extinguishing equipment with fixed sheet body] Next, an embodiment of a fire extinguishing system in which a sheet body is fixedly installed will be described in detail. As shown in Fig. 27, this embodiment is characterized in that a sheet body 14 (14a) of a fire extinguisher 12 is fixedly installed in a protected area 10 in an unfolded state.

[0162] The fire extinguisher 12 of this embodiment is composed of a holder 15 and a sheet body 14 (14a), and one end of the sheet body 14 (14a) is fixed to the holder 15. For example, the fire extinguisher 12 is configured such that the holder 15 is fixed to the upper part of a predetermined wall surface of a room that will become the protected compartment 10, the sheet body 14 (14a) with one end fixed to the holder 15 is lowered along the wall surface, and the sheet body 14 (14a) is fixed to the wall surface with rivets or the like so that it does not swing. The rest of the configuration is the same as the embodiment of FIG. 2.

[0163] According to this embodiment, the sheet deployment structure shown in Fig. 26 is not necessary, so the structure is simplified and costs can be reduced. Note that the sheet body 14 (14a) to be fixedly arranged may be the sheet body 14 (14b) in Fig. 20 or the sheet body 14 (14c) in Fig. 21 instead.

[0164] Fig. 28 shows another embodiment of the fire extinguisher 12 in which a sheet body is fixed and installed, and the fire extinguisher 12 of this embodiment is composed of a holder 15 and a sheet body 14 (line sheet 14d), and the sheet body 14 (14d) has a plurality of discharge ports 24 arranged in a single straight line. The sheet body 14 (14d) can be manufactured in the same manner as shown in Fig. 17 or Fig. 22. The sheet body 14 (14d) is connected to a fire extinguisher pipe 16, and when a fire occurs, the fire extinguisher stored in an outdoor operation box installed outside the house is opened and operated to receive a supply of fire extinguishing agent, which is then discharged from the discharge port 24 provided in the sheet body 14 (14d) to suppress and extinguish the fire.

[0165] In the sheet body 14 (14d) of this embodiment, the entire discharge port row is composed of only discharge port row elements in which the discharge ports 24 serving as discharge points are arranged in a single horizontal straight line, thereby suppressing fires by linear discharge of extinguishing agent. Note that the sheet body 14 (14d) may be arranged in the up-down direction (vertical direction) or in an oblique direction.

[0166] In addition, a surface discharge of the extinguishing agent may be obtained by using a plurality of sheet bodies 14 (14d). For example, by arranging a plurality of sheet bodies 14 (14d) in parallel on the same surface, the extinguishing agent can be discharged surface-wise as a whole.

[0167] [m. Modifications of the present invention] Modifications of the fire extinguishing system according to the present invention will be described in more detail. In addition to the above-described embodiment, the fire extinguishing system according to the present invention includes the following modifications.

[0168] (Outdoor operation box) In the above embodiment, the fire extinguisher is stored in an outdoor operation box that can be opened and closed freely, and is opened when a fire occurs, but this is not limited to the above. For example, a compartment such as a room that can be accessed from the outside of the building may be provided, and the fire extinguisher may be stored there, or the fire extinguisher may be placed in an exposed state in a place that is not exposed to rain, such as under the eaves. As long as the extinguisher can be opened from the outside of the building, the installation location is not limited and may be any location.

[0169] (Target buildings) In the above embodiment, a general detached house is taken as an example of a building in which the fire extinguishing system is installed, but the target may be a group home for elderly people, an apartment building, etc. In this case, since the number of rooms to be protected areas increases, the protected areas may be divided into groups of a predetermined number, and the outdoor operation box 18 may be installed outside the building for each group.

[0170] Furthermore, the fire extinguisher of the present invention can be applied to, for example, factories, schools, government offices, and other appropriate facilities. Of course, the protected area is not limited to a room, and may be any appropriate area.

[0171] (Layout of discharge port of sheet body) In the above embodiment, a plurality of discharge ports 24 are arranged at various locations on one side of the sheet body 14, but the present invention is not limited to this, and a plurality of discharge ports 24 may be arranged at various locations on both sides of the sheet body 14. The sheet body 14 having a plurality of discharge ports 24 arranged at various locations on both sides is used when the fire extinguishing device 12 is installed on the ceiling or the like in the center of the room that serves as the protected section 10, and when a fire breaks out, the sheet body 14 is deployed from above to below, and the extinguishing agent is surface-discharged to both sides from the plurality of discharge ports 24 on each side of the sheet to extinguish and suppress the fire.

[0172] (Fire extinguishing agent distribution route) In the above embodiment, the extinguishing agent flow path 34 is formed by sheet piping or by sewing with a sewing machine or by adhesion using waterproof thread, but the present invention is not limited to this. For example, the extinguishing agent flow path may be formed by using a tube made of resin or the like.

[0173] (Sheet body) The shape of the sheet body 14 is not limited to that in the embodiment, and may be any suitable shape other than rectangular, such as circular, elliptical, polygonal, etc. The above embodiment has been described as an example in which one sheet body 14 is installed in one protected area, but the number of sheet bodies 14 installed in one protected area is arbitrary.

[0174] Any number of extinguishing agent supply ports, pressure buffer devices, and pressure buffer areas may be provided for each sheet body.
