Description

The present invention relates to a fire extinguishing device and a fire extinguishing method that extinguishes fires by covering the source of the fire.

Conventionally, fire extinguishers are installed in ordinary homes and apartment buildings as fire extinguishing equipment. In addition, fire extinguishing sheets containing a fire extinguishing agent that are placed over the source of a fire to extinguish the fire are known (Patent Documents 1 and 2).

Japanese Patent Application Publication No. 54-125898 Japanese Patent Application Publication No. 10-201871

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, there is a possibility that the scattered extinguishing agent may cause secondary damage, such as soiling or damaging surrounding objects.

Conventional fire extinguishing sheets are filled with extinguishing agents (such as powder extinguishing agents or extinguishing liquids) in a soluble sheet (film). When placed over the source of a fire, the sheet melts due to the heat from the fire, releasing the extinguishing agent and putting out the fire. However, because the amount of extinguishing agent contained in the fire extinguishing sheet is relatively small, it is possible that the sheet may not be effective enough to extinguish 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.

The objective of the present invention is to provide a fire extinguisher and a fire extinguishing method that is easy for users to use, can reliably extinguish fires, and can reduce secondary damage.

(Fire extinguishing methods)
The present invention provides a fire extinguishing method using the above-mentioned fire extinguishing device,
The user places the sheet body over the source of the fire with one side facing the source of the fire, and operates the fire extinguishing agent supply device to release the extinguishing agent over a surface from a discharge port arranged on one side, thereby discharging the extinguishing agent onto the source of the fire covered by the sheet body and extinguishing the fire.

(Basic Effects)
In the fire extinguisher of the present invention, when extinguishing a fire or other combustion, a 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 reliable extinguishing of the fire.

Here, "source of fire" is a concept that refers to the source of fire (combustion source) and its surroundings. Furthermore, "area release" refers to the release of extinguishing agent over a surface from multiple locations by arranging multiple release ports (release points) in various locations on one side of the sheet body, that is, the release of extinguishing agent from release ports arranged in various locations on one surface of the sheet body, thereby dispersing the extinguishing agent over a wide area of one surface of the sheet body. Furthermore, "cover" and "cover" are not limited to covering or covering the entire object (for example, the source of fire) in its entirety, but also include covering or covering a part of the object.

"Fire extinguishing" is the concept of suppressing or putting out a fire. Here, "suppression" means, for example, preventing the spread of fire, the burning speed, or the expansion of the scale of the fire.

In addition, 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 extinguisher can be simplified.

(Effect of the shape of the sheet body)
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.

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

(Effect of keeping the sheet body in a non-deployed state under normal circumstances)
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.

(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.

(Effect of Sheet Body 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.

(Effect of Sheet Body 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 mass production is also easy, thereby further reducing manufacturing costs.

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

(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.

(Effect of pressure buffering means)
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 extinguishant flow path of the fire extinguisher, there is a possibility that it may be damaged. Therefore, by providing a buffer area (buffer area), for example, as a pressure buffering means on the inlet side of the extinguishant flow path of the sheet body, the increase (or rate of increase) of the extinguishant supply pressure from the fire extinguisher can be kept below a predetermined level, preventing damage to the extinguishant flow path or release port.

(Effect of connecting means of 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.

In addition, if a fire occurs outside the protected area in a location where no fire extinguishing equipment is installed, the user can disconnect the connection means, remove the fire extinguisher from the extinguishing agent piping, and carry it to the location in question for use. This allows the extinguisher that is normally installed to be used in combination with the extinguisher for the fire extinguishing equipment, making it easier to maintain the fire extinguisher and reducing operating costs.

(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 extinguishing agent piping, the connecting means, or the extinguishing agent supply port, the increase (or rate of increase) in the extinguishing agent supply pressure from the fire extinguisher can be kept below a predetermined level, thereby preventing damage to the extinguishing agent flow path or discharge port.

Below, an embodiment of a fire extinguisher according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiment.

[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.

A "sheet body" is something 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; for example, this concept includes cloth-like bodies 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.

The sheet body is normally in an undeployed state, but when extinguishing a fire, it is deployed and placed over the source of the 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, deploys it, and places it over the source of the fire, releasing the extinguishing agent from one side of the sheet body.

The term "extinguishing agent flow path" refers to a path provided in a sheet body through which the extinguishing agent flows, and is a concept that includes, for example, sheet piping arranged between cloth bodies. Note that "sheet piping" refers to, for example, flexible piping that can be crushed and deformed freely and expands when extinguishing agent is passed through it.

The term "extinguishing agent supply port" refers to an inlet for supplying 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.

The "discharge port" is an outlet for the extinguishing agent supplied from the extinguishing agent supply port to the extinguishing agent flow 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.

The term "extinguishing agent piping" refers to flexible piping that supplies extinguishing agent to the extinguishing agent flow path of the sheet body, and includes, for example, a rubber or synthetic resin hose that supplies extinguishing agent to a fire extinguishing device.

The term "fire extinguishing agent supply device" refers to a device that supplies extinguishing agent to the 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.

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

In the following explanation, we will explain the specific details of an embodiment of a fire extinguisher when the "source of fire" is "facility or equipment in the room" and the "fire extinguishing agent supply device" is a "fire extinguisher."

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

[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 is one that is equipped with an extinguishing agent flow path 14, an extinguishing agent supply port 16, and a release port 18.

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 the one side 12a faces the source of the fire), and extinguishes the fire by releasing a fire extinguishing agent from the one side 12a.

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, including facilities, equipment, 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-deployed state when not in use, and can be opened and used in a deployed state when extinguishing a fire.

Here, in the unfolded state of the sheet body 12 shown in the figure, the up-down direction 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.

(b1. Extinguishing agent distribution path 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 supply port 16, which serves as a pressure buffering means, and continuous with the buffer area 20 is provided an extinguishing agent flow path 14 in which a plurality of release ports 18 are arranged at various locations on one surface 12a.

The extinguishing agent flow path 14 is formed vertically in the shape of a ladder, for example, with five stages, and a buffer area 20 with an extinguishing agent supply port 16 is 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.

The extinguishing agent flow path 14 is formed to supply extinguishing agent 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 extinguishing agent supplied to the multiple outlets 18 in the same row approximately uniform, and to align the discharge pattern (angular distribution) and discharge amount in the same row.

The shape of the extinguishing agent flow channel 14 that supplies extinguishing agent to the multiple discharge ports 18 is not limited to the ladder shape shown in the figure, but may include other suitable shapes such as a tree shape or a tournament shape. In addition, if the discharge pressure of the multiple discharge ports 18 is to be approximately uniform, the thickness (cross-sectional area) of the extinguishing agent flow channel 14 may be made thicker on the extinguishing agent supply port 16 side and thinner as it moves away from the extinguishing agent supply port 16. In addition, the number and arrangement of the discharge ports 18 provided corresponding to the extinguishing agent flow channel 14 are arbitrary.

(b2. Discharge port)
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.

The sheet body 12 is placed over the source of the fire with one side 12a facing down (towards the source of the fire), and the sheet surface opposite the one side 12a becomes the other side 12b exposed to the outside.

[c. Fire extinguishing agent piping]
The extinguishing agent piping is a flexible piping that supplies extinguishing agent to the extinguishing agent flow 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.

[d. Fire extinguishing agent supply equipment]
(d1. Fire extinguisher)
The extinguishant supply device supplies extinguishant to an 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 extinguisher 24 has a main container filled with a predetermined extinguishant, for example, a powder fire extinguishant or a reinforced liquid fire extinguishant, under pressure, and when a user removes a safety pin 34 and pushes down a lever 35, the extinguisher opens and supplies extinguishant to the fire extinguisher hose 25.

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.

The 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 uses a known connection joint similar to that used to detachably connect a hose to a water faucet with a single touch. Here, the extinguisher nozzle 30 is a nozzle that is attached to the end of the hose of the fire extinguisher 24 by removing it and attaching a separately prepared fire extinguisher nozzle 30 in advance, but is not limited to this.

(d2. Fire extinguisher connection part)
Figure 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, and is provided with a dedicated fire extinguisher nozzle 30 at the tip of the fire extinguisher hose 25 and a fire extinguisher connection port 32 at the other end of the extinguishant supply hose 26, making the extinguishant supply hose 26 and the fire extinguisher hose 25 detachable.

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.

(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.

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

In addition to or in place of the buffer area 20 (pressure buffering means), the 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 that 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 flow path 14 and the discharge port 18 are not damaged).

[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.

The first cover sheet 36 and the second cover sheet 38 are, for example, a fabric-like body having fireproofing, fire resistance, heat resistance or flame retardancy, and can withstand high heat of, for example, 1200°C, and may be, but is not limited to, what is also called a fireproof sheet, fireproof curtain, fireproof screen, etc.

The first cover sheet 36 and the second cover sheet 38 each have heat-shielding, flame-shielding, or smoke-shielding properties. The second cover sheet 38, whose bottom surface in the figure is the other surface 12b, may be an ordinary cloth-like body that does not have fireproofing, fire resistance, heat resistance, flame retardancy, heat-shielding, flame-shielding, or smoke-shielding properties.

Next, multiple weights 22 are placed at intervals along the outer edge of the second cover sheet 38, and the weights 22 are fixed along the outer edge of the sheet, for example by folding inward the protruding portion 38a formed on the outer edge and gluing it.

The weight 22 is, for example, a material such as lead of a predetermined length, and when the user unfolds the sheet body 12 and throws it to cover the source of the fire, the weight 22 on the outer edge allows the sheet body 12 to be spread out like a casting net and thrown, and the sheet body 12 can be easily thrown to cover the source of the fire in its unfolded state.

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, and thus preventing the extinguishing agent from leaking and scattering from the source of the fire covered by the sheet body 12, thereby improving the extinguishing effect and reducing contamination of the surrounding area.

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 upholstery into a pipe shape and connecting it in a ladder shape (the connection parts are allowed to flow), and as shown in FIG. 4(A), it is freely deformable by being crushed and flattened under normal circumstances, and when extinguishing agent 41 is supplied, it expands as shown in FIG. 4(B), forming 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.

As shown in FIG. 3, the second to fifth tiers of sheet piping 40 following the first tier in which the buffer area 20 is provided have multiple discharge ports 18, and the first cover sheet 36 has through holes 45 that correspond to the discharge ports 18.

As shown in FIG. 5, the discharge port 18 is composed of a base 42 and a clamping ring 44. A screw shaft 46 stands upright on the base 42, and a discharge hole 50 penetrates the screw shaft 46. The clamping ring 44 has a screw hole 48 and is fixed by screwing it onto the screw shaft 46.

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 in the sheet piping 40 and then glued and fixed by the adhesive part 43. The screw shaft 46 taken out from the opening in the sheet piping 40 is taken out through the through hole 45 in the first cover sheet 36, and the clamping ring 44 is screwed into the through hole, so that the sheet piping 40 is clamped and fixed in place on the back surface of the first cover sheet 36.

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 with a sewing machine using waterproof thread, completing the sheet body 12 shown in FIG. 1.

[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.

The first cover sheet 36 and the second cover sheet 38 are the same as those in the manufacturing method shown in FIG. 3, and the first waterproof sheet 56 and the second waterproof sheet 58 are made of a cloth such as polyester used for covering umbrellas, as with the sheet piping 40 in the manufacturing method shown in 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 that does not have fireproofing, fire resistance, heat resistance or flame retardancy.

The extinguishing agent supply port 16 is arranged in the first waterproof sheet 56 in correspondence with the extinguishing agent flow path 14 to be formed, and a through hole 55 is formed in correspondence with the discharge port 18 to be fixed, and a through hole 45 is formed in the first cover sheet 36. Also, as in the manufacturing method of FIG. 3, a weight 22 is fixed to the outer periphery of the second cover sheet 38.

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 fixed by adhesive 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 upright, and the clamping ring 44 with the screw hole 48.

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

Figure 9 (A) shows the extinguishing agent flow path 14 formed by the stitching portion 60. The extinguishing agent flow 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. Normally, the extinguishing agent flow path 14 is in a crushed state, but when the extinguishing agent 41 is supplied, as shown in Figure 9 (B), it expands to increase the cross-sectional area and allows 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, but when the extinguishing agent is supplied, it expands to form the buffer area 20.

[g. Location 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.

For example, as shown in FIG. 10(A), when the target of the fire extinguisher 10 of this embodiment is a sofa 64 placed in a smoking area, the sheet body 12 is placed on a stand 62 installed near the sofa 64.

As shown in FIG. 11(A), the stand 62 has a pole 72 standing on a base 70, a hemispherical sheet hanging part 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.

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

As shown in FIG. 10(B), if a fire indicated by fire source 66 occurs on sofa 64 due to embers from smoking, etc., a user 68 removes sheet body 12 from fire extinguisher 10 hung on stand 62, spreads out 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 weights are placed on the outer edge of sheet body 12, it is possible to throw sheet body 12 while spreading it out like a casting net, and it is possible to easily and reliably cover the source of the fire on sofa 64.

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 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 lower side 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.

At this time, the pressure of the extinguishing agent causes the sheet body 12 to try to rise from the state where it is covered by the source of the fire, but the weights placed on the outer periphery prevent the sheet body 12 from rising, so the sheet body 12 does not roll up or fly away. In addition, because the extinguishing agent is released while covered by the sheet body 12, leakage and scattering of the extinguishing agent into the surrounding area is suppressed, making it possible to not only extinguish the fire, but also reduce damage to the surrounding area.

In addition, the fire extinguisher 24 releases 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 is used up, the user 68 can continue to release extinguishant and ensure fire extinguishing by removing 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 replacing the used fire extinguisher 24 with an unused fire extinguisher 24 (a fire extinguisher hose 25 to which a separately prepared fire extinguisher nozzle 30 has already been attached) that has been prepared separately.

In addition, in the event of a fire occurring 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, eliminating the need to increase the number of fire extinguishers installed and reducing the increase in maintenance costs. In addition, the base 70 of the stand 62 shown in FIG. 11 may be provided with caster wheels or the like to configure the fire extinguisher 10 as a cart so that it can be moved to the source of the fire.

[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.

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

When extinguishing a fire, the user 68 opens the case lid 84 as shown in the case lid 84a, removes and unfolds the folded sheet body 12, and places it over the source of the fire with one side 12a facing downward. Next, by opening the fire extinguisher 24 exposed to the outside, the extinguishing agent is supplied to the sheet body 12 via the extinguishing agent supply hose 26, and the extinguishing agent is discharged from various outlets on one side 12 of the sheet body 12 to the covered source of the 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.

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

The structure and method for folding the 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 the sheet body 12 when the sheet body 12 is unfolded. Here, the folds of the sheet body 12 are shown by dashed lines, and by dividing the sheet body 12 vertically and horizontally into 12, the sheet body 12 is folded, for example, to 1/12 of its original size, as shown in Figs. 13(A) to (D).

As shown in Figures 13(A) to (D), the retaining band 88 constitutes a retaining means for freely releasably holding the sheet body 12 in a predetermined folded state, the sheet body 12 having been folded multiple times with the first fold being a dashed line passing through the fixed position of the handle 86, together with a male hook 90 provided on the retaining band 88 and a female hook 92 provided at a predetermined position on the other surface 12b.

In more detail, the handle 86 is fixed at both ends to the center along the first fold (the horizontal fold in the illustration) of the other surface 12b so as to form a half-moon shape. The stop band 88 has its base end (one end) fixed to the sheet surface between the fixing parts at both ends of the handle 86, and its tip (other end) passes through the handle 86 so that it can be positioned on the opposite side.

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 folded compactly as shown in FIG. 13(D).

The method of folding the 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 the sheet body 12 folded to 1/2 size from the front to the center, and then fold the right side on top of it from the front to the center to obtain the folded state of 1/6 size shown in FIG. 13(C).

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 shown in FIG. 13(D). 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.

As a result, for example, a sheet body 12 that is 150 centimeters in length and width can be folded to a size of approximately 37.5 centimeters in length and 50 centimeters in width (area is 1/12 of the size), reducing the installation space required during normal use. Note that it is desirable to fold the sheet body 12 to the smallest size that can be achieved without straining the folding (within a range that does not damage the sheet piping 40 or the discharge port 18 when folded).

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 it over the source of the fire with one side 12a facing down. By holding the handle 86 at this time, the sheet body 12 can be easily and safely placed over the source of the fire.

[i. Normal arrangement with the sheet body 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.

In this case, the sheet body 12 is made to be of a size that can adequately 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 the extinguishant supply hose 26 via the extinguisher connection part 28.

In this embodiment, if 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.
