Description

[Technical field]

[0001] The present invention relates to a fire extinguisher and a fire extinguishing method for extinguishing a fire by covering the source of the fire. [Background technology]

[0002] Conventionally, fire extinguishers are installed as fire extinguishing equipment in ordinary homes, apartment buildings, etc. Also, fire extinguishing sheets containing a fire extinguishing agent that extinguish a fire by covering the source of the fire are known (Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 54-125898 [Patent Document 2] Japanese Patent Application Publication No. 10-201871 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with fire extinguishers, due to the inexperience of the operator, it may not be easy to accurately aim the extinguishing agent at the source of the fire, the released extinguishing agent may scatter over a wide area, resulting in insufficient extinguishing efficiency. Furthermore, the scattered extinguishing agent may cause secondary damage, such as staining or damaging surrounding objects.

[0005] In addition, conventional fire extinguishing sheets are filled with extinguishing agents (such as powder extinguishing agents or extinguishing liquids) in a soluble sheet (film), and when placed over the source of a fire, they melt due to the heat of the fire, releasing the extinguishing agent and putting out the fire. However, since the amount of extinguishing agent contained in the fire extinguishing sheet is relatively small, it is expected that there will be cases where the sheet is not effective enough in extinguishing a fire. Also, when there is no flame, such as in a smoldering fire, it takes time for the sheet to melt and release the extinguishing agent, leaving the possibility that it will not be useful for initial fire extinguishing.

[0006] An object of the present invention is to provide a fire extinguisher and a fire extinguishing method which are easy for a user to use, can reliably extinguish a fire, and can reduce secondary damage. [Means for solving the problem]

[0008] (Location of outlet) A plurality of discharge ports are provided in the extinguishing agent flow path.

[0009] (Weight on the outer edge of the sheet) The sheet body has a weight provided on at least a portion of the outer periphery.

[0010] (The sheet is normally placed in a non-deployed state.) The sheet body is normally in a non-deployed state, and when extinguishing a fire, it is deployed and placed over the source of the fire.

[0011] (Normal seat arrangement) The sheet body is normally stored in a storage means in a non-expanded state or hung on a stand means.

[0012] (Seat body in unfolded state) When in the unfolded state, the sheet body is folded into a handbag-like state.

[0013] (Configuration for folding the sheet body) The sheet body is A handle is provided on the other side, which is the reverse side of the first side. a holding means for releasably holding the folded state in which the folding member is folded along a straight line passing through a fixed position of the handle as an initial fold; Equipped with.

[0014] (The sheet is deployed and placed on the target for extinguishing fire under normal circumstances.) The sheet body is normally deployed in a deployed state so as to cover a predetermined target for fire extinguishing.

[0015] (Sheet structure 1) the sheet body has a collapsible and deformable sheet pipe that forms an extinguishing agent flow path and has an extinguishing agent supply port and a discharge port disposed therein; The sheet piping is disposed between the two cover sheets.

[0016] (Sheet structure 2) The sheet body has a first cover sheet, a first waterproof sheet, a second waterproof sheet and a second cover sheet, and is sewn together in a stacked state in the order of the first cover sheet, the first waterproof sheet, the second waterproof sheet and the second cover sheet so as to form an extinguishing agent distribution path between the first waterproof sheet and the second waterproof sheet, with an extinguishing agent supply inlet and an outlet being disposed therebetween, and an outlet being provided on at least one of the first cover sheet and first waterproof sheet side and the second cover sheet and second waterproof sheet side of the extinguishing agent distribution path.

[0017] (Cloth-like body) The cover sheet has at least one surface made of a fabric having fire prevention, fire resistance, heat resistance, heat insulation, flame insulation, smoke insulation or flame retardancy.

[0018] (Pressure buffering means) The sheet body is provided with a pressure buffer means at a predetermined position in the extinguishant flow path for temporarily retaining the extinguishant from the extinguishant supply device to keep the increase in extinguishant supply pressure below a predetermined level.

[0019] (Means for connecting extinguishing agent supply devices) A connecting means is provided for detachably connecting the extinguishing agent piping and the extinguishing agent supply device.

[0020] (Second pressure buffer means) At least one of the extinguishant piping, the connecting means, and the extinguishant supply port provided in the sheet body is provided with a second pressure buffer means for limiting the increase in extinguishant supply pressure to a predetermined level or less.

[0021] (Fire extinguishing method) The present invention provides a fire extinguishing method using the above-mentioned fire extinguishing device, The user covers the source of the fire with the sheet body facing the source of the fire, and operates the fire extinguishing agent supply device to release the extinguishing agent from the outlet arranged on one side, thereby releasing the extinguishing agent onto the source of the fire covered by the sheet body and putting out the fire. Effect of the Invention

[0022] (Basic Effects) In the fire extinguisher of the present invention, when extinguishing a fire or other combustion, the user places one side of the sheet body facing down over, for example, the source of the fire, and opens the extinguishing agent supplying device, for example a fire extinguisher, to release the extinguishing agent from a release port located on one side of the sheet body, i.e., the side facing the target to be extinguished. This allows the extinguishing agent to be efficiently released over the source of the fire covered by the sheet body, and a synergistic effect is achieved between, for example, cooling by the extinguishing agent and the blocking of the oxygen supply (suffocation) by covering the source of the fire with the sheet body, thereby ensuring fire extinguishing.

[0023] Here, "source of fire" is a concept that indicates the source of fire (combustion source) and its surroundings. Also, "area release" refers to discharging extinguishing agent from multiple locations over a surface by arranging multiple outlets (release points) at various locations on one side of a sheet body, that is, discharging extinguishing agent from outlets arranged at various locations on one surface of the sheet body, thereby dispersing extinguishing agent over a wide area of ​​one surface of the sheet body. Also, "cover" and "cover" are not limited to covering or covering the entire object (e.g., source of fire) in its entirety, but include covering or covering a part of the object.

[0024] In addition, "extinguishing" is the concept of suppressing or extinguishing a fire. Here, "suppression" refers to, for example, suppressing the spread of a fire, the burning speed, or the expansion of the burning scale.

[0025] Furthermore, the sheet body only needs to be sized to cover the anticipated target of fire extinguishing, including equipment and locations that may be the source of fire, such as gas ranges and heating appliances, and by making it relatively small in size, the fire extinguishing equipment can be simplified.

[0026] (Effect of sheet shape) In addition, by making the sheet shape correspond to the target of extinguishing, which is the source of the fire, when a fire occurs in the target of extinguishing, such as a gas range or heating appliance, it is possible to release the extinguishing agent by covering it so that gaps are less likely to form at the boundary between the space on the side of the source of the fire (target of extinguishing) covered by the sheet and the outside space.

[0027] (Effect of weight on the outer edge of the sheet) In addition, by providing weights (weights) along the outer periphery of the sheet, when a user unfolds the sheet and throws it to cover the source of the fire, the weights on the outer periphery allow the sheet to be spread out like a throwing net, allowing the sheet to be easily and reliably used to cover the source of the fire. In addition, the weights on the outer periphery prevent the sheet from floating up when the extinguishing agent is released, suppressing leakage and scattering of the extinguishing agent from the space covered by the sheet, improving the fire extinguishing effect and reducing damage to the surrounding area.

[0028] (Effect of keeping the sheet body in a non-deployed state under normal conditions) In addition, the sheet body is normally placed near the target to be extinguished and in an undeployed state, for example by being stored in a storage means or hung on a stand means, and preferably folded into a handbag-like state so that it requires less installation space.In the event of a fire, for example, the user can quickly take it out and unfold it without having to search for a place to put it, cover the source of the fire, and release the extinguishing agent from the fire-extinguishing sheet surface of the sheet body.

[0029] (The effect of placing the sheet on the target of fire extinguishing under normal circumstances) In addition, under normal circumstances, the sheet body is placed in an unfolded state to cover a specified fire extinguishing object, for example, furniture such as a bed using an electric blanket that may be the source of a fire. In the event of a fire breaking out in the fire extinguishing object, the user does not need to unfold the sheet body to cover the source of the fire, but can quickly extinguish the fire by simply opening the extinguishing agent supply device, for example, a fire extinguisher.

[0030] (Effect of Sheet Structure 1) In addition, the sheet body is configured such that a collapsible and deformable sheet piping having an extinguishing agent supply port and a discharge port arranged therein is placed between two cover sheets (a first cover sheet and a second cover sheet), making it possible to manufacture a sheet body equipped with an extinguishing agent flow path and a discharge port simply, easily and at low cost.

[0031] (Effect of Sheet Structure 2) In addition, the sheet body is sewn together in the order of the first cover sheet, the first waterproof sheet, the second waterproof sheet and the second cover sheet so as to form an extinguishing agent flow path in which an extinguishing agent supply port and a release port are arranged, and a release port is provided on at least one of the first cover sheet and first waterproof sheet side and the second cover sheet and second waterproof sheet side of the extinguishing agent flow path, so that the formation of the extinguishing agent flow path and the integration of the stacked sheet bodies are simultaneously achieved by sewing, and the sheet body can be made even more simply and easily and is also easily mass-produced, thereby further reducing manufacturing costs.

[0032] 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.

[0033] (Cover sheet effect) In addition, the cover sheets located on the front and back sides of the sheet body use a cloth-like material that has fire resistance, fire resistance, heat resistance, heat insulation, flame insulation or smoke insulation properties on at least one side that has an outlet, so that the extinguishing agent can continue to be released without being burned even when exposed to heat or flames from a fire.

[0034] (Effect of pressure buffering measures) In addition, when a user opens a fire extinguisher to supply extinguishant to the extinguishant flow path of the sheet body, the accumulated pressure of the fire 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 extinguishing device, it may cause damage, etc. Therefore, by providing a buffer area (buffer area) as a pressure buffering means on the entrance side of the extinguisher flow path of the sheet body, the increase (or rate of increase) of the extinguisher supply pressure from the fire extinguisher can be kept below a predetermined level, preventing damage to the extinguisher flow path or release port.

[0035] (Effect of connecting means for fire extinguisher) In addition, since the extinguishing agent piping and the fire extinguisher are connected detachably by the connecting means, for example, when it is necessary to continue extinguishing a fire even after the extinguisher has been used up, the used extinguisher can be replaced with an unused extinguisher to continue discharging the extinguishing agent, thereby enabling reliable extinguishing of the fire.

[0036] In addition, when a fire occurs in a location outside the protected area where a fire extinguisher is not installed, the user can disconnect the connecting means, remove the fire extinguisher from the extinguishing agent piping, and carry it to the location for use. This means that the fire extinguisher that is normally installed can be used in combination with the fire extinguisher for the fire extinguishing equipment, making it easier to maintain the fire extinguisher and reducing operating costs.

[0037] (Effect of the second pressure buffering means) In addition, by providing a second pressure buffer means, such as an orifice, in at least one of the extinguishant piping, the connecting means, or the extinguishant supply port, the increase (or rate of increase) in the extinguishant supply pressure from the fire extinguisher can be kept below a predetermined level, thereby preventing damage to the extinguishant flow path or discharge port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a fire extinguisher 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.

[0040] [Basic Concept of the Embodiment] The embodiment generally relates to a fire extinguisher that a user places over the source of a fire to extinguish the fire. Here, the term "fire extinguisher" refers to a device that extinguishes a fire by discharging or scattering an extinguishing agent, and 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.

[0041] A "sheet body" is a body that has an outlet on one side, is flexible and thin (thick) with the required width, and can be used to cover or encase something, and is a concept that includes, for example, a cloth-like body that can be stored in an unfolded state and deployed when in use (to extinguish a fire). Here, "one side of the sheet body" refers to the side that faces downwards when the user places the sheet body over the source of the fire (the side facing the source of the fire), and also refers to the side that has the function of releasing extinguishing agent.

[0042] The sheet body is normally in an undeployed state, and is deployed to cover the source of the fire when extinguishing a fire. The sheet body is normally placed near the target of fire extinguishing and in an undeployed state, for example, stored in a storage means or hung on a stand means, and when a fire breaks out, the user quickly takes it out and deploys it to cover the source of the fire, causing the extinguishing agent to be released from one side of the sheet body.

[0043] The term "extinguishing agent flow path" refers to a path through which the extinguishing agent flows, which is provided in 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.

[0044] 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.

[0045] 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 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.

[0046] Further, the term "extinguishing agent piping" refers to flexible piping that supplies extinguishing agent to the extinguishing agent distribution path of the sheet body, and is a concept that includes, for example, a rubber or synthetic resin hose that supplies extinguishing agent to a fire extinguishing device.

[0047] In addition, the term "fire extinguishing agent supply device" refers to a device that supplies extinguishing agent to extinguishing agent piping when a specified operation is performed by a user, and is a concept that includes fire extinguishers that supply extinguishing agents such as liquid extinguishing agents, enhanced extinguishing liquids, and powder extinguishing agents.

[0048] As a result, the fire extinguisher of this embodiment is configured so that when a specified operation is performed on the fire extinguisher supply device with one side facing the source of the fire, the extinguisher supplied from the fire extinguisher supply device via the extinguisher piping to the extinguisher distribution path is released from the release port on one side.

[0049] In the following description, specific details of an embodiment of a fire extinguisher will be described for a case where the "source of fire" is "facility or equipment in the room" and the "fire extinguishing agent supplying device" is a "fire extinguisher."

Modifications of the present invention

[0051] [a. Overview of fire extinguishing equipment] As shown in FIG. 1, a fire extinguisher 10 of this embodiment is composed of a sheet body 12, a fire extinguisher supply hose 26 which functions as an extinguishant piping, and a fire extinguisher 24.

[0052] [b. Sheet body] The sheet body 12 is placed over the source of the fire to release extinguishing agent to extinguish the fire, and its structure and configuration are arbitrary, but one example includes an extinguishing agent flow path 14, an extinguishing agent supply port 16, and a release port 18.

[0053] The sheet body 12 is, for example, a flexible cloth-like body, and as shown in FIG. 1(A), it is placed over the source of the fire with one side 12a facing the source of the fire (so that one side 12a faces the source of the fire), and extinguishes the fire by releasing a fire extinguishing agent from one side 12a.

[0054] In addition, the sheet body 12 is a rectangular sheet body, for example a square sheet body, whose length and width correspond to the target of fire extinguishing, which includes equipment, devices, and locations that may be the source of fire, such as gas ranges and heating appliances installed in homes, etc., and because it is flexible, it can be folded up and kept in a non-expanded state when not in use, and can be opened and used in an expanded state when extinguishing a fire.

[0055] Here, in the illustrated unfolded state, the up-down direction of the sheet body 12 is the vertical direction, the left-right direction is the horizontal direction, and the depth direction into the paper surface is the thickness direction shown in Fig. 1(B). Note that the vertical direction and the horizontal direction are directions that are determined relatively when the sheet body 12 in the unfolded state is viewed from any direction.

[0056] (b1. Extinguishing agent distribution route and extinguishing agent supply port) The extinguishing agent flow path 14 is a passage provided in the sheet body 12 through which the extinguishing agent flows, and its structure and configuration are arbitrary, but for example, an extinguishing agent supply port 16 is arranged at one end edge (the lower end edge in the figure) of the sheet body 12, and continuous with the extinguishing agent supply port 16 is provided a buffer area (buffer area) 20 shown by dotted lines inside the extinguishing agent flow path 14 which serves as a pressure buffering means, and continuous with the buffer area 20 is provided with a plurality of discharge ports 18 at various locations on one surface 12a.

[0057] The extinguishing agent flow path 14 is formed vertically in the shape of a ladder having, for example, five stages, with a buffer area 20 having an extinguishing agent supply port 16 provided in the center of the first stage, which is the lowest stage, and discharge ports 18 are arranged in, for example, four locations each, on the second to fifth stages from the bottom.

[0058] In addition, the extinguishant flow path 14 is formed to supply extinguishant from both sides of the horizontal row of outlets 18 arranged in the second to fifth rows from the bottom. This makes it possible to make the discharge pressure of the extinguishant supplied to the multiple outlets 18 in the same row approximately uniform, and to make the discharge pattern (angle distribution) and discharge amount in the same row uniform.

[0059] The shape of the extinguishant flow path 14 for supplying the extinguishant to the multiple discharge ports 18 is not limited to the ladder shape shown in the figure, 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 18 is made substantially uniform, the thickness (cross-sectional area) of the extinguishant flow path 14 may be made thicker on the extinguishant supply port 16 side and thinner as it moves away from the extinguishant supply port 16. In addition, the number and arrangement of the discharge ports 18 provided corresponding to the extinguishant flow path 14 are arbitrary.

[0060] (b2. Outlet) The discharge port 18 is an exit port for the extinguishing agent supplied from the extinguishing agent supply port 16 to the extinguishing agent flow path 14, and may have any structure or configuration. For example, as shown in FIG. 1(B), the discharge port 18 opens on one surface 12a of the sheet body 12, and discharges the extinguishing agent supplied from the extinguishing agent supply port 16 to the extinguishing agent flow path 14 from various locations on the one surface 12a of the sheet body 12 to extinguish a fire.

[0061] The sheet body 12 is placed over the source of the fire with one surface 12a facing down (facing the source of the fire), and at this time the sheet surface opposite to the one surface 12a becomes the other surface 12b exposed to the outside.

[0062] [c. Fire extinguishing agent piping] The extinguishing agent piping is a flexible piping that supplies extinguishing agent to the extinguishing agent distribution path 14 of the sheet body 12, and its structure, configuration, and type are arbitrary, but for example, an extinguishing agent supply hose 26 is provided, and the extinguishing agent supply hose 26 is, for example, a flexible hose made of rubber or synthetic resin.

[0063] [d. Fire extinguishing agent supply equipment] (d1. Fire extinguisher) The extinguishant supply device supplies extinguishant to extinguishant supply hose 26 provided as an extinguishant pipe when a user performs a predetermined operation, and the structure, function and type are arbitrary, but for example, a fire extinguisher 24 is used and connected to one end of the extinguishant supply hose 26. The fire extinguisher 24 has a main container filled with a predetermined extinguishant, such as a powder fire extinguishant or a reinforced liquid fire extinguishant, under pressure, and when a user removes safety pin 34 and pushes down lever 35, the plug is opened and extinguishant is supplied to the fire extinguisher hose 25.

[0064] The sheet body 12 and the fire extinguisher 24 are connected by connecting one end of a fire extinguishant supply hose 26 to the fire extinguishant supply port 16 of the sheet body 12, and connecting the other end of the fire extinguisher supply hose 26 to the fire extinguisher nozzle 30 at the tip of the fire extinguisher hose 25 of the fire extinguisher 24 via a fire extinguisher connection part 28.

[0065] The fire extinguisher connection part 28, which is the connection means, is composed of a fire extinguisher nozzle 30 and a fire extinguisher connection port 32, and for example, a known connection joint similar to that for detachably connecting a hose to a water faucet with a single touch is used. Here, the fire extinguisher nozzle 30 is a nozzle that is attached to the end of the hose of the fire extinguisher 24 in advance by removing it, and a separately prepared fire extinguisher nozzle 30 is attached in advance, but is not limited to this.

[0066] (d2. Fire extinguisher connection part) FIG. 2 shows an example of a fire extinguisher connection part 28, which is composed of a fire extinguisher nozzle 30 and a fire extinguisher connection port 32. A dedicated fire extinguisher nozzle 30 is provided at the tip of the fire extinguisher hose 25, and the fire extinguisher connection port 32 is provided at the other end of the extinguishant supply hose 26, making the extinguishant supply hose 26 and the fire extinguisher hose 25 detachable.

[0067] The fire extinguisher nozzle 30 is connected and fixed by inserting the nipple 52 equipped with an O-ring into the opening of the fire extinguisher connection port 32, and the connected fire extinguisher nozzle 30 is removed by sliding the slider 54 in the direction of the arrow shown in the figure.

[0068] (d3. Buffer Area) When a specified operation is performed, the fire extinguisher 24 opens and supplies extinguishing agent to the sheet body 12. However, since the accumulated pressure of the fire extinguisher 24 is high, for example, 0.7 MPa to 0.98 MPa, the extinguishant flow path 14 and the discharge port 18 of the sheet body 12 may be damaged by the supply of high-pressure extinguishing agent when the fire extinguisher 24 is opened.

[0069] Therefore, the extinguishing agent flow path 14 is provided with a buffer area 20 (buffer area) on the inlet side as a pressure buffer means, which temporarily retains the extinguishing agent from the fire extinguisher 24 in the initial stage after the start of extinguishing agent supply, thereby keeping the increase (or rate of increase) of the extinguishing agent pressure below a predetermined level, thereby preventing damage to the extinguishing agent flow path 14 and the discharge outlet 18.

[0070] In addition, instead of or in addition to the buffer area 20 (pressure buffering means), the fire extinguisher connection part 28, the extinguishant supply hose 26, the extinguishant supply port 16, etc. may be provided with a pressure buffering device (second pressure buffering means), such as an orifice, which adjusts the rise (or rate of rise) of the extinguishant pressure from the fire extinguisher 24 to a predetermined level (to the extent that the extinguishant distribution path 14 and the discharge port 18 are not damaged).

[0071] [e. Sheet body manufacturing method 1] The sheet body 12 of this embodiment shown in Fig. 1 is manufactured, for example, by the method shown in Fig. 3. First, a first cover sheet 36 and a second cover sheet 38 of a predetermined size are prepared. The illustrated upper surface of the first cover sheet 36 becomes one surface 12a in Fig. 1 when the sheet body 12 is placed over the source of the fire, and the illustrated lower surface of the second cover sheet 38 becomes the other surface 12b in Fig. 1(B) when the sheet body 12 is placed over the source of the fire. Both sheets are shown in a horizontally arranged state.

[0072] The first cover sheet 36 and the second cover sheet 38 are, for example, a cloth-like material having fire resistance, fire resistance, heat resistance or flame retardancy, and can withstand high temperatures of, for example, 1200°C, and may be what is also called a fire-resistant sheet, fire-resistant curtain, fire-resistant screen, etc., but are not limited to these.

[0073] Furthermore, the first cover sheet 36 and the second cover sheet 38 each have heat insulation properties, flame insulation properties, smoke insulation properties, etc. The second cover sheet 38, whose lower surface in the figure is the other surface 12b, may be an ordinary cloth-like body that does not have fire prevention properties, fire resistance, heat resistance, flame retardancy, heat insulation properties, flame insulation properties, or smoke insulation properties.

[0074] Next, multiple weights 22 are arranged at intervals along the outer peripheral edge of the second cover sheet 38, and the weights 22 are fixed along the outer peripheral edge of the sheet, for example, by folding the protrusions 38a formed on the outer peripheral edge inward and gluing them.

[0075] The weight 22 is, for example, a member such as lead of a prescribed length, and when a user unfolds the sheet body 12 and throws it to cover the source of the fire, the sheet body 12 can be spread out like a casting net by the weight 22 on the outer periphery and thrown, and the sheet body 12 can be easily spread out to cover the source of the fire.

[0076] In addition, the weight 22 presses down on the outer edge of the sheet body 12 when it is deployed over the source of the fire, thereby preventing the sheet body 12 from floating up due to the release of the extinguishing agent, thereby preventing the extinguishing agent from leaking and scattering from the source of the fire covered by the sheet body 12, thereby improving the fire-extinguishing effect and reducing damage to the surrounding area.

[0077] Next, a five-stage ladder-shaped sheet piping 40 is prepared. The sheet piping 40 is made by forming a cloth material such as polyester used for lining umbrellas into a pipe shape and connecting them in a ladder shape (connections are made to be able to flow), and as shown in Fig. 4(A) it is freely deformable by being crushed and flattened under normal conditions, and when extinguishing agent 41 is supplied it expands as shown in Fig. 4(B) to form an extinguishing agent flow path 14. The buffer area 20 provided next to the extinguishing agent supply port 16 is also normally crushed and flattened, and when extinguishing agent is supplied it expands to form the buffer area 20.

[0078] Also, as shown in FIG. 3, a plurality of discharge ports 18 are arranged in the second to fifth stages of the sheet piping 40 following the first stage in which the buffer area 20 is provided, and through holes 45 are opened in the first cover sheet 36 corresponding to the discharge ports 18.

[0079] 5, the discharge port 18 is composed of a base 42 and a clamping ring 44. A threaded shaft 46 stands up from the base 42, and a discharge hole 50 penetrates the threaded shaft 46. The clamping ring 44 has a threaded hole 48 and is fixed by screwing it onto the threaded shaft 46.

[0080] As shown in Fig. 5(A), the base 42 is placed inside the sheet piping 40, and as shown in Fig. 5(C), for example, the screw shaft 46 is taken out from an opening provided in the sheet piping 40 and bonded and fixed by an adhesive part 43. The screw shaft 46 taken out from the opening of the sheet piping 40 is taken out through a through hole 45 of the first cover sheet 36, and a clamping ring 44 is screwed into the through hole, thereby clamping and fixing the sheet piping 40 to the back surface of the first cover sheet 36.

[0081] Next, as shown in FIG. 3, the sheet piping 40 provided with the extinguishing agent supply port 16, the buffer area 20 and the discharge port 18 is sandwiched between the first cover sheet 36 and the second cover sheet 38, and the first cover sheet 36 and the second cover sheet 38 are glued or sewn together by a sewing machine using waterproof thread, thereby completing the sheet body 12 shown in FIG. 1.

[0082] [f. Sheet body manufacturing method 2] 6 shows another method for producing the sheet body 12. First, the first cover sheet 36, the first waterproof sheet 56, the second waterproof sheet 58 and the second cover sheet 38 of predetermined sizes are prepared. Note that each sheet is shown in a horizontally arranged state.

[0083] The first cover sheet 36 and the second cover sheet 38 are the same as those in the manufacturing method of Fig. 3, and the first waterproof sheet 56 and the second waterproof sheet 58 are made of a cloth-like material such as polyester used for covering umbrellas, for example, in the same manner as the sheet piping 40 in the manufacturing method of Fig. 3. The second cover sheet 38, whose bottom surface in the figure is the other surface 12b, may be made of an ordinary cloth-like material that does not have fireproofing, fire resistance, heat resistance or flame retardancy.

[0084] In the first waterproof sheet 56, the extinguishing agent supply port 16 is arranged corresponding to the extinguishing agent flow path 14 to be formed, and through holes 55 are formed corresponding to the discharge port 18 to be fixed, and through holes 45 are formed in the first cover sheet 36. Also, as in the manufacturing method of FIG. 3, a weight 22 is fixed to the outer peripheral edge of the second cover sheet 38.

[0085] The first cover sheet 36 and the first waterproof sheet 56 are overlapped with the through holes 45, 55 aligned, and the base 42 is adhered and fixed by the adhesive part 43 with the screw shaft 46 of the discharge port 18 taken out from the through holes 45, 55 as shown in Fig. 7. The structure of the discharge port 18 is the same as that shown in Fig. 5, and is composed of the base 42 with the screw shaft 46 that passes through the discharge hole 50 and stands up, and a clamping ring 44 with a screw hole 48.

[0086] Next, with the first cover sheet 36 and the first waterproof sheet 56 fixed by the discharge port 18, the second waterproof sheet 58 and the second cover sheet 38 are overlapped as shown in Fig. 6, and in this state, as shown in Fig. 8, a sewing operation is performed with a sewing machine or the like using waterproof thread to form a seam 60, thereby creating the buffer area 20 and the extinguishing agent distribution path 14. Furthermore, with the sheets overlapping, they are integrated into the sheet body 12 by a seam 61 sewn along the outer periphery of the sheets except for the weight 22 portion.

[0087] Fig. 9(A) shows the extinguishing agent distribution path 14 formed by the stitching portion 60. The extinguishing agent distribution path 14 is formed by sewing the first cover sheet 36, the first waterproof sheet 56, the second waterproof sheet 58, and the second cover sheet 38 together, for example, by a sewing machine using waterproof thread, at the stitching portion 60, and is normally in a crushed state, but when the extinguishing agent 41 is supplied, as shown in Fig. 9(B), it expands so that the cross-sectional area increases, allowing the extinguishing agent 41 to flow. The buffer area 20 formed by the stitching portion 60 next to the extinguishing agent supply port 16 is also normally crushed and flattened, and expands to form the buffer area 20 when the extinguishing agent is supplied.

[0088] [g. Placement and use of fire extinguishing equipment] Next, the arrangement of the fire extinguisher of this embodiment in normal times and its use in the event of a fire will be described in detail.

[0089] For example, as shown in FIG. 10(A), when the target of extinguishing a fire is a sofa 64 placed in a smoking area or the like, the fire extinguisher 10 of this embodiment is placed in a state in which the sheet body 12 is hung on a stand 62 installed near the sofa 64.

[0090] As shown in FIG. 11(A), for example, the stand 62 has a pole 72 standing on a base 70, a hemispherical sheet hanging portion 74 at the tip of the pole 72, a hose holder 76 midway along the pole 72, and a fire extinguisher holder 78 on the base 70.

[0091] As shown in FIG. 11(B), the fire extinguisher 10 is installed in such a manner that the sheet body 12, with one surface 12a facing inward, is hung with approximately the center portion thereof over a sheet hanging portion 74 at the tip of a pole 72, like a closed umbrella, the fire extinguisher 24 is placed in a fire extinguisher holder 78 on the base 70, and the extinguishing agent supply hose 26 is hung on the hose holder 76 in a rolled up state, so that in the event of a fire, the user can easily remove the sheet body 12 from the stand 62 for use.

[0092] As shown in Fig. 10(B), when a fire indicated by fire source 66 occurs on sofa 64 due to embers from smoking, a user 68 removes sheet body 12 of fire extinguisher 10 hung on stand 62, spreads sheet body 12, turns one surface 12a downward, and places it over the source of the fire on sofa 64 indicated by fire source 66. At this time, since a weight is placed on the outer periphery of sheet body 12, sheet body 12 can be spread and thrown like a casting net, and the source of the fire on sofa 64 can be easily and reliably covered.

[0093] Next, as shown in FIG. 10(C), when a user 68 opens the fire extinguisher 24 placed on the stand 62 by removing the safety pin 34 shown in FIG. 11(B) and pushing down the lever 35, the extinguisher 24 supplies the extinguishant to the sheet body 12 via the extinguishant supply hose 26, and the extinguishant is released from the outlets provided in various places on the surface 12a of the underside of the sheet body 12, so that the extinguishant spreads evenly over the source of the fire covered by the sheet body 12, making it possible to effectively extinguish the fire in a short time.

[0094] At this time, the sheet body 12 tries to rise from the state where it is covered by the source of fire due to the discharge pressure of the extinguishing agent, but the weights arranged on the outer periphery prevent the sheet body 12 from rising, so the sheet body 12 is not rolled up or blown away. In addition, since the extinguishing agent is discharged while covered by the sheet body 12, leakage and scattering of the extinguishing agent to the surroundings is suppressed, making it possible to extinguish the fire and reduce damage to the surrounding area.

[0095] In addition, the fire extinguisher 24 releases the extinguishing agent for a short period of time, such as about 10 seconds. If the fire is not extinguished even after the fire extinguisher 24 has been used up, the user 68 can remove the fire extinguisher nozzle 30 from the fire extinguisher connection port 32 of the fire extinguisher connection part 28 shown in Figures 1 and 2 and replace the used fire extinguisher 24 with an unused fire extinguisher 24 that has been prepared separately in advance (a fire extinguisher hose 25 to which a separately prepared fire extinguisher nozzle 30 has already been attached), thereby continuing the release of the extinguishing agent and ensuring reliable extinguishing of the fire.

[0096] In addition, when a fire occurs at another location where the fire extinguisher 10 of this embodiment is not installed, the user 68 can remove the fire extinguisher 24 from the extinguishing agent supply hose 26 and carry it to the source of the fire for use, so there is no need to increase the number of fire extinguishers installed, and the increase in maintenance costs can be reduced. Note that the fire extinguisher 10 may be made movable to the source of the fire by providing caster wheels or the like to the base 70 of the stand 62 shown in Fig. 11 to make it movable as a dolly.

[0097] [h. Normal arrangement of fire extinguishing equipment] (h1. Storage case) The installation form of the fire extinguisher 10 under normal circumstances may be an installation form using a storage case 80 shown in FIG. 12, other than the installation using the stand 62 shown in FIG.

[0098] The storage case 80 shown in FIG. 12 has a case body 82 with a case lid 84 that can be opened and closed freely, and stores the sheet body 12 in a folded state, the extinguishing agent supply hose 26 in a rolled up state, and the fire extinguisher 24 inside the case body 82.

[0099] When extinguishing a fire, the user 68 opens the case lid 84 as shown in the case lid 84a, takes out and unfolds the folded sheet body 12, and places it over the source of the fire with one surface 12a facing downward. Next, by opening the fire extinguisher 24 exposed to the outside, the extinguishing agent is supplied to the sheet body 12 through the extinguishing agent supply hose 26, and the extinguishing agent is discharged from the discharge ports in various places on the one surface 12 of the sheet body 12 to the source of the covered fire, thereby extinguishing the fire. Note that the case body 82 may be provided with caster wheels or the like to configure the fire extinguisher 10 as a dolly so that it can be moved to the source of the fire.

[0100] (h2. Folding the sheet body) 13, the sheet body 12 may be folded into a handbag-like shape and hung on a stand 62 shown in FIG. 11 or stored in a storage case 80 shown in FIG.

[0101] The configuration and method for folding sheet body 12 into a handbag-like state are arbitrary, but for example, as shown in Fig. 13(A), a handle 86 and a fastening band 88 are provided on the other surface 12b of sheet body 12 in an unfolded state. Here, the folds of sheet body 12 are shown by dashed dotted lines, and by dividing sheet body 12 vertically and horizontally into 12 parts, sheet body 12 is folded to, for example, 1 / 12 of its original size, as shown in Figs. 13(A) to (D).

[0102] As shown in Figures 13(A) to (D), the fastening band 88 constitutes a retaining means for releasably retaining a predetermined folded state of the sheet body 12 that has been folded multiple times with the dot-dash line passing through the fixed position of the handle 86 as the first fold, together with a male hook 90 provided on the fastening band 88 and a female hook 92 provided at a predetermined position on the other surface 12b.

[0103] More specifically, the handle 86 has both ends fixed to the center along the first fold (the central horizontal fold in the drawing) of the other surface 12b so as to form a half-moon shape. The retaining band 88 has a base end (one end) fixed to the sheet surface between the fixing parts at both ends of the handle 86, and a tip end (the other end) passing through the handle 86 so as to be positioned on the opposite side.

[0104] For example, a male hook 90 is provided on the tip side of the fastening band 88, and a female hook 92 is provided at a predetermined position on the other surface 12b corresponding to this. The female hook 92 is provided at a predetermined position where the male hook 90 of the fastening band 88 can be engaged when the sheet body 12 is in a small folded state as shown in Fig. 13(D).

[0105] The method of folding sheet body 12 is as follows: first, fold it in half from the state shown in Fig. 13(A) up and down to obtain the folded state of 1 / 2 size shown in Fig. 13(B). Next, fold the left side of sheet body 12 folded to 1 / 2 size from front to center, and then fold the right side on top of it from front to center to obtain the folded state of 1 / 6 size shown in Fig. 13(C).

[0106] Next, the lower side of the sheet body 12 that has been folded to 1 / 6 size is folded from the front to the top so that the female hook 92 is at the front, resulting in the folded state of 1 / 12 size as shown in Figure 13(D), and finally, the male hook 90 of the fastening band 88 that has been passed through the inside of the handle 86 is engaged with the female hook 92 to maintain the folded state.

[0107] As a result, for example, a sheet body 12 that is 150 cm long and 150 cm wide can be folded to a size of approximately 37.5 cm long and 50 cm wide (area is 1 / 12 of the size), reducing the installation space required during normal use. Note that the sheet body 12 is preferably folded to the smallest size that can be achieved within reasonable limits (within limits that do not damage the sheet piping 40 or the discharge port 18 by folding).

[0108] When putting out a fire, the user takes out the folded sheet body 12 by holding the handle 86, unfolds the sheet body 12 by removing the fastening band 88, and places the sheet body 12 with one surface 12a facing down over the source of the fire. By holding the handle 86 at that time, the sheet body 12 can be easily and safely placed over the source of the fire.

[0109] [i. Normal arrangement with the sheet covering the fire extinguishing target] As another example of the normal arrangement of this embodiment, as shown in FIG. 14, the sheet body 12 of the fire extinguisher 10 may be placed with one side 12a facing down to cover a predetermined fire extinguishing target, for example, furniture such as a bed 94 on which bedding 96 including an electric blanket is placed.

[0110] In this case, the sheet body 12 is made to have a size that can sufficiently cover the bed 94. The fire extinguisher 24 is placed near the bed 94 to be extinguished or outside the room in which the bed 94 is located, and is connected to the extinguishant supply port 16 of the sheet body 12 by a fire extinguisher supply hose 26 via a fire extinguisher connection part 28.

[0111] In this embodiment, when a fire breaks out in the bed 94 that is the target of extinguishing, the user can quickly extinguish the fire by simply opening the fire extinguisher 24, without the need for the user to unfold the sheet body 12 to cover the source of the fire.

[0112] [j. Modifications of the present invention] (Applies to) In the above embodiment, the fire extinguishing target of the fire extinguishing apparatus is, for example, equipment, devices, locations, etc. that may be the source of a fire in a residence. However, the fire extinguishing apparatus can also be applied to fire extinguishing targets such as equipment, devices, locations, etc. that may be the source of a fire in a factory, school, government office, warehouse, or other appropriate facility.

[0113] (Sheet body) In the above embodiment, the sheet body is rectangular in shape, but is not limited thereto. For example, the sheet body may be circular, elliptical, or a polygon other than a rectangle, or a combination of these shapes, depending on the target of extinguishing. In addition, in the above embodiment, weights are arranged along the outer periphery of the sheet body, but the present invention is not limited thereto, and the sheet body may not use weights.

[0114] (Fire extinguishing agent distribution route) In the above embodiment, the extinguishing agent flow path 14 is formed by sheet piping or by sewing with a sewing machine or by gluing using waterproof thread, but the formation of the extinguishing agent flow path 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.

[0115] (Fire extinguishing agent supply equipment) In the above embodiment, a fire extinguisher is used as an example of the extinguishing agent supplying device, but the device is not limited to this and may be any portable extinguishing agent supplying device. For example, a simple accumulator-type water supply pump may be used. The accumulator-type water supply pump stores an extinguishing agent in a container, compresses the air in the container by manual operation, and supplies and releases the extinguishing agent to the sheet body using the compressed air.

[0116] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages of the present invention, and is not limited to the numerical values ​​shown in the above embodiment. [Explanation of symbols]
