Description

Technical Field

[0001] The present invention relates to a fire extinguishing device that extinguishes a fire by covering a fire source with a sheet body and a fire extinguishing device storage device.

Background Art

[0002] Conventionally, in private houses, apartment houses, etc., fire extinguishers are installed as fire extinguishing devices. Also, a fire extinguishing sheet in which a fire extinguishing agent that extinguishes a fire by covering the fire source is enclosed is known (Patent Documents 1 and 2).

[0003] However, in the case of a fire extinguisher, it is difficult for the operator to accurately direct the hose of the fire extinguisher toward the fire source and discharge the fire extinguishing agent, for example, because the operator is not used to handling the fire extinguisher. Also, since the discharged fire extinguishing agent scatters over a wider area than the fire source, sufficient fire extinguishing efficiency cannot be obtained, and there is a possibility that secondary damage such as the surrounding objects being soiled or damaged by the scattered fire extinguishing agent may occur.

[0004] Further, in a conventional fire extinguishing sheet, a fire extinguishing agent (powder fire extinguishing agent, fire extinguishing liquid, etc.) is enclosed in a soluble sheet (film), and when the sheet is covered so as to cover the fire source, the sheet melts by receiving heat from the fire, and the enclosed fire extinguishing agent is discharged to extinguish the fire. However, since the amount of the fire extinguishing agent enclosed in the fire extinguishing sheet is relatively small, it is assumed that a sufficient fire extinguishing effect cannot be obtained. Also, in the case of a smoldering fire where there is no flame, heat cannot be sufficiently received from the fire source, and it takes time until the sheet melts and discharges the fire extinguishing agent, leaving the possibility that it will not be useful for initial fire extinguishing.

[0005] In order to solve this problem, the applicant of the present application has proposed a fire extinguishing device in which a fire extinguishing agent flow path is provided in a sheet body that covers the fire source, a plurality of discharge ports for discharging the fire extinguishing agent are arranged corresponding to the fire extinguishing agent flow path on one surface of the sheet body (the surface on the fire source side when covered so as to cover the fire source), and a fire extinguisher is connected to the sheet body by a fire extinguishing agent supply hose (Patent Document 3).

[0006] According to the fire extinguishing device using such a sheet body, when extinguishing a fire, after the user covers the fire source with the sheet body with one side of the sheet body facing down, the fire extinguisher is opened to discharge the fire extinguishing agent in a surface discharge manner from the discharge port arranged on one side of the sheet body. Thus, regardless of the type of fire, the fire extinguishing agent can be discharged efficiently without taking time, and the synergistic effect of the cooling effect of the fire extinguishing agent and the blocking (asphyxiation) effect of oxygen supply from outside the sheet body due to covering the fire source with the sheet body can be obtained, making it possible to extinguish the fire more reliably.

Summary of the Invention

Problems to be Solved by the Invention

[0008] By the way, in the conventional fire extinguishing device using a sheet body, usually, the sheet body is arranged in an undeployed state in the fire extinguishing target area. When a fire occurs, the user needs to pick up the sheet body, unfold it, and then cover the fire source. The undeployed state means, for example, a state of being stored in a storage box, a state of being hung on a stand, or a state of being folded into a handbag shape so as to require less storage space.

[0009] However, in the case of a fire extinguishing device using a conventional sheet body, after the sheet body in the non-expanded state is widely expanded and deployed, an operation of covering the sheet body over the fire source from above is required. In a situation where extinguishing the fire is urgent due to a fire, in a hurry to deploy the sheet body and cover the fire source, it is assumed that the sheet body cannot be properly covered over the fire source.

[0010] Therefore, weights are arranged on the outer peripheral edge of the conventional sheet body, enabling the user to deploy the sheet body by throwing it like a throwing net, assisting the user in the deployment operation of the sheet body, and making it possible to cover the fire source with the sheet body.

[0011] However, in order to throw the sheet body while deploying it like a throwing net, special ways of holding and throwing are required. Since many users do not have such experience, it is assumed that the sheet body cannot be properly covered over the fire source while being successfully deployed.

[0012] An object of the present invention is to provide a fire extinguishing device and a fire extinguishing device storage device that enable a user to easily and more reliably cover a fire source with a sheet body to extinguish a fire, and concomitantly suppress the scattering of a fire extinguishing agent to the surroundings and reduce secondary damage.

Means for Solving the Problems

[0013] (Fire extinguishing device storage device) The present invention is a fire extinguishing device storage device for storing a fire extinguishing device including at least a sheet body that is normally in a non-expanded state wound in a rod shape and unfolds by rolling from the non-expanded state to cover a fire source, characterized by including a sheet body holder portion (holder 74 in the embodiment) that holds the sheet body in a non-expanded state and an upright state.

[0014] (Sheet body support portion) A fire extinguishing device including a sheet body wound in a rod shape with a shaft member having a hollow portion as the central axis and the wound state being defined as the non-expanded state is the object to be stored, Furthermore, it is characterized by including a seat body support part (support pole 84 in the embodiment) that stands up from the bottom of the holder part and is fitted into the hollow part of the shaft member.

[0015] (Height of the seat body support part) The height of the seat body support part shall be lower than the height of the seat body in the standing state.

[0016] (Cap part) Furthermore, it includes a cap part (cap 76 in the embodiment) that is detachably attached to the upper part of the seat body held by the seat body holder part.

[0017] (Fire extinguishing agent supply appliance holder part and fire extinguishing agent pipe holder part) In addition to the seat body, a fire extinguishing appliance including a fire extinguishing agent pipe for supplying a fire extinguishing agent to the seat body and a fire extinguishing agent supply appliance for supplying the fire extinguishing agent to the seat body via the fire extinguishing agent pipe is the object to be stored. Furthermore, a fire extinguishing agent supply appliance holder part (fire extinguisher holder 78 in the embodiment) for arranging the fire extinguishing agent supply appliance, a fire extinguishing agent pipe holder part (pole 80 provided with a hose holder 82 in the embodiment) for arranging the fire extinguishing agent pipe in a wound state, is provided, Each of the seat body holder part, the fire extinguishing agent supply appliance holder part, and the fire extinguishing pipe holder is provided independently on the pedestal.

[0018] (Fire extinguishing appliance) In another form of the present invention, there is a fire extinguishing appliance, a seat body having one side capable of covering the fire source, a fire extinguishing agent flow path provided in the seat body, a discharge port provided corresponding to the fire extinguishing agent flow path on at least one side of the seat body for discharging the fire extinguishing agent supplied to the fire extinguishing agent flow path, a fire extinguishing agent pipe having one end side connected to the fire extinguishing agent flow path for supplying the fire extinguishing agent to the fire extinguishing agent flow path, a fire extinguishing agent supply appliance having the other end side of the fire extinguishing agent pipe connected thereto for supplying the fire extinguishing agent to the fire extinguishing agent pipe, A storage section for storing a sheet body, a fire extinguishing agent pipe, and a fire extinguishing agent supply device, comprising, covering the fire source with the sheet body with one surface provided with an outlet or the other surface opposite to one surface facing the fire source side, and when a predetermined operation is performed by the fire extinguishing agent supply device, discharging the fire extinguishing agent supplied from the fire extinguishing agent supply device to the fire extinguishing agent flow path through the fire extinguishing agent pipe from the outlet to extinguish the fire, The sheet body is, Normally, it is stored in the storage section in a non-expanded state wound in a rod shape with a shaft member as the central axis and in an upright state, During fire extinguishing, it is taken out from the storage section and unfolds by rolling from the non-expanded state toward the fire source side to cover the fire source. It is characterized in that.

[0019] Here, "surface discharge" means that a plurality of outlets (discharge points) are arranged at various positions on the surface of the sheet body from which the fire extinguishing agent is discharged, so that the fire extinguishing agent is discharged from a plurality of locations in a surface manner, that is, the fire extinguishing agent is discharged from the outlets arranged at various positions on the sheet body surface, and the fire extinguishing agent is sprayed from a wide range of the sheet body surface.

Effect of the Invention

[0020] (Basic effect) In the fire extinguishing device of the present invention, normally the sheet body is arranged in a non-expanded state wound in a rod shape, and during fire extinguishing, the user can unfold the sheet body by rolling the sheet body wound in a rod shape toward the fire source. Therefore, there is no need for a special way of holding and throwing like a throwing net to unfold the sheet body, and the sheet body can be unfolded simply and more reliably to cover the fire source.

[0021] Also, with one side of the sheet body facing the fire source and covering the fire source, when the user operates the fire extinguisher supply device, such as a fire extinguisher, to open the valve and discharge the fire extinguishing agent in a surface discharge manner from the discharge port arranged on one side of the sheet body, the fire extinguishing agent can be efficiently discharged onto the fire source covered by the sheet body, and a synergistic effect can be obtained between the cooling effect of the fire extinguishing agent and the effect of blocking (asphyxiation) the oxygen supply from outside the sheet body due to covering with the sheet body, enabling more reliable fire extinguishing. In addition, leakage and scattering of the fire extinguishing agent from the space covered by the sheet body can be suppressed to enhance the fire extinguishing effect, and secondary damage caused by soiling of the surroundings can also be reduced.

[0022] Further, when discharge ports for discharging the fire extinguishing agent are arranged on one side of the sheet body and the other side opposite to the one side, the sheet body can be deployed toward the fire source without being conscious of the side facing the fire source side, and when covering the fire source with the sheet body, a situation where the side provided with the discharge port is not facing the fire source side can be avoided.

[0023] (Effect by deployment with the end portion side of the sheet body held) When the sheet body is deployed to cover the fire source with the end portion side of the sheet body on the fire extinguisher side held, the area covered by the deployed sheet body can be easily determined before the deployment of the sheet body, and the position of the deployed sheet body can be suppressed from deviating from the position of the fire source, so that the sheet body can be more reliably covered over the fire source.

[0024] (Effect of the sheet body wound with one side on the outside) Even in the non-deployed state where the sheet body is wound in a rod shape, the user can recognize the side provided with the discharge port, and it is possible to prevent the sheet body from being deployed with the side not provided with the discharge port facing the fire source side by mistake.

[0025] (Effect of the sheet body wound around the shaft member) Also, by keeping the sheet body wound around the shaft member in the non-deployed state, when the sheet body is rolled toward the fire source, due to the inertial force of the shaft member, the sheet body can roll quickly and cover the fire source rapidly.

[0026] (Effect of the shaft member provided on the starting end side of the sheet body) In addition, since the shaft member is provided on the starting end side of the sheet body, when the sheet body is unfolded to cover the fire source and the fire extinguishing agent is discharged from the discharge port of the sheet body, the upward floating of the sheet body can be suppressed by the weight of the shaft member, the leakage and scattering of the fire extinguishing agent from the space covered by the sheet body can be suppressed, the fire extinguishing effect can be enhanced, and the pollution of the surroundings can be reduced.

[0027] Furthermore, when the sheet body and the shaft member are mutually bound by the first string-like member or the first net member, the shaft member will roll forward beyond the sheet body while pulling the unfolding sheet body, so the shaft member can assist in the unfolding of the sheet body and the sheet body can be unfolded more reliably. Also, when using a net member, the operation of winding the used sheet body becomes easier compared to using a string-like member.

[0028] (Effect of operating the sheet body by the second string-like member) Moreover, it is equipped with an operation part operated by the user. The operation part is bound by the second string-like member on the ending end side of the sheet body. During fire extinguishing, by operating the second string-like member through the operation part, operations such as rolling and unfolding the sheet body from the non-unfolded state and moving the position of the unfolded sheet body are enabled. Therefore, the user can keep a further distance from the fire source corresponding to the length of the second string-like member during fire extinguishing and can operate the sheet body from a position safe from the fire source. Also, since it is an operation at a position far from the fire source, the possibility of the sheet body being unfolded at a position deviated from the fire source increases, but the problem of the positional deviation of the sheet body with respect to the fire source is solved by being able to adjust the position of the unfolded sheet body by operating the second string-like member through the operation part. Also, if the sheet body is displaced too much with respect to the fire source and it is difficult to adjust the position, the unfolded sheet body can be recovered to the hand and rewound, and the sheet body can be thrown again. The same effect is obtained when using a second net member instead of the second string-like member, but the operation of winding the used sheet body becomes easier compared to using a string-like member.

[0029] (Effect of the through-hole of the fire extinguishing agent pipe in the operation unit) In addition, the operation unit can limit the movement of the fire extinguishing agent pipe by inserting the fire extinguishing agent pipe that connects the fire extinguisher and the fire extinguishing agent flow path of the seat body through the through-hole of the operation unit, and can prevent the fire extinguishing agent pipe from interfering with the user handling the fire extinguisher.

[0030] (Effect of the third string-like member of the seat body) In addition, the seat body is provided with a third string-like member that enables the user to adjust the position of the deployed seat body. When the deployed seat body is displaced with respect to the fire source, the user can operate the third string-like member to easily and safely move the seat body without directly touching the seat body.

[0031] (Effect of the weight of the seat body) In addition, the seat body is provided with a weight, for example, at least a part of the peripheral edge of the deployed seat body, so that when the seat body covers the fire source and the fire extinguishing agent is discharged from the discharge port of the seat body, the weight can further suppress the lifting of the seat body, suppress the leakage and scattering of the fire extinguishing agent from the space covered by the seat body, enhance the fire extinguishing effect, and reduce the surrounding contamination.

[0032] (Effect of the fire extinguishing method) Since the same effects as those of the above-described fire extinguishing appliance can be obtained by the fire extinguishing method of the present invention, the description thereof is omitted.

Embodiment for Carrying Out the Invention

[0034] Hereinafter, embodiments of the fire extinguishing device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by the following embodiments.

[0035] [Basic Concept of the Embodiment] The embodiment generally relates to a fire extinguishing device that extinguishes a fire by covering a fire source with a sheet body. Here, the "fire extinguishing device" is one that extinguishes a fire by discharging or spraying a fire extinguishing agent. The fire extinguishing device according to the present embodiment includes a sheet body provided with a fire extinguishing agent flow path and a discharge port, a fire extinguishing agent pipe, and a fire extinguishing agent supply device.

[0036] Also, the "fire source" is a concept that includes the ignition source (combustion source) and its surroundings. Also, "covering so as to cover" is not limited to covering the entire object (for example, the fire source) or covering it entirely, but includes covering a part of the object or covering a part of it. Also, "extinguishing a fire" is a concept of suppressing combustion or extinguishing a fire, and "suppressing" means, for example, suppressing the spread of fire, the combustion rate, or the expansion of the combustion scale.

[0037] The "sheet body" has one surface that can cover a fire source, is provided with a fire extinguishing agent flow path and a discharge port corresponding to the fire extinguishing agent flow path on at least one surface, is in a non-expanded state usually wound in a rod shape, and unfolds by rolling towards the fire source side from the non-expanded state during fire extinguishing to cover the fire source. Its shape, size, etc. are arbitrary as long as it can cover the fire source, and it includes, for example, a cloth-like body with flexibility and thinness (thickness).

[0038] Here, the "one side of the sheet body" means the surface that faces downward (the surface on the fire side) when the user covers the fire source with the sheet body. Also, it is sufficient if there is an outlet provided on at least one side, and the outlet may be provided on one side of the sheet body and the other side opposite to the one side. Naturally, when outlets are provided on both the one side and the other side of the sheet body, either side can face the fire side. Also, it does not prevent providing an outlet on, for example, the side surface of the sheet body which is not the surface covering the fire source.

[0039] Also, the "wound in a rod shape" includes both those wound in a hollow shape (tubular shape) with a cavity inside and those wound in a solid shape without a cavity inside, and is a concept that includes both those wound with one side facing outward and those wound with one side facing inward.

[0040] Also, the "fire extinguishing agent flow path" is a flow path in the sheet body for the fire extinguishing agent supplied from the fire extinguishing agent pipe provided in the sheet body, and is a concept that includes, for example, a sheet pipe arranged between the cloth-like bodies constituting the sheet body. Note that the "sheet pipe" refers to, for example, a flexible pipe that can be crushed and deformed and expands by flowing the fire extinguishing agent through it.

[0041] Also, the "outlet" is an outlet for the fire extinguishing agent supplied to the fire extinguishing agent flow path, and discharges the fire extinguishing agent from at least one side of the sheet body. For example, it discharges the fire extinguishing agent in a surface manner from a plurality of openings arranged at various positions on one side of the sheet body.

[0042] Also, the "sheet body" may be rolled from the non-expanded state and deployed while the end portion side of the winding located on the outer peripheral side in the state of being wound in a rod shape is held. Here, the "end portion of the winding" is the edge portion of the sheet body at a position close to the user who rolled the sheet body when the sheet body is rolled and deployed to cover the fire source. Also, the "held state" includes the state held by the user, the state fixed and held at any position in the fire extinguishing target area, etc.

[0043] Alternatively, the "sheet body" may be wound around the shaft member in an undeveloped state. Note that since the shaft member exists along the central axis of the sheet body wound around it, it is wound in a cylindrical shape.

[0044] Moreover, the "shaft member" is a rod-shaped member around which the sheet body is wound, and its structure and size can be arbitrary as long as it can wind the sheet body. Also, the "rod-shaped" concept includes both hollow and solid ones.

[0045] Furthermore, the shaft member may be provided on the starting part side located on the inner peripheral side in a state where it is wound around the rod shape of the sheet body. Here, the "starting part" is the edge of the sheet body located far from the user who rolls the sheet body when the sheet body is rolled out to cover the fire source.

[0046] The method of providing the shaft member with respect to the starting part of the sheet body is arbitrary. For example, the shaft member and the sheet body are bound to each other by a first string-shaped member or a first net member of a predetermined length. Here, the "first string-shaped member" is, for example, a string formed by bundling fibers made of a material having fire resistance, heat resistance, or flame retardancy, and the "first net member" is, for example, a net formed from the first string-shaped member. Also, the method of binding the shaft member and the sheet body is arbitrary, but in order to assist the unfolding of the sheet body while pulling the unfolding sheet body, it is desirable to bind the shaft member and the sheet body so that the central axis of the shaft member can maintain a state substantially orthogonal to the rolling direction of the sheet body until the rolling of the shaft member ends.

[0047] In addition, the "sheet body" may be provided with a third string-shaped member that enables the user to adjust the position of the unfolded sheet body. Also, the "third string-shaped member" has the same concept as the "first string-shaped member".

[0048] Moreover, the "sheet body" may have a weight provided on at least a part of the peripheral edge of the unfolded sheet body.

[0049] In addition, the "fire extinguishing agent pipe" is a pipe for supplying a fire extinguishing agent to the fire extinguishing agent flow path of the sheet body, preferably having flexibility, and includes, for example, hoses, tubes, etc. made of rubber, synthetic resin, cloth, other woven fabrics, or composite materials thereof.

[0050] In addition, the "fire extinguishing agent supply device" is something that supplies a fire extinguishing agent to the fire extinguishing agent pipe when a predetermined operation is performed by a user, and includes, for example, fire extinguishers that supply fire extinguishing agents such as liquid fire extinguishing agents, fire intensifying liquids, powder fire extinguishing agents, etc.

[0051] Furthermore, the fire extinguishing device may further include an operation part that the user operates. The "operation part" is for enabling the user to perform operations of rolling and deploying the sheet body from the non-deployed state and moving the position of the deployed sheet body without touching the sheet body. Here, the "operation of moving the position of the deployed sheet body" includes concepts such as operations for adjusting the deployed sheet body to an appropriate position relative to the fire source or moving the sheet body back to the user's hand.

[0052] Specifically, the operation part is fastened to the end part of the winding of the sheet body on the fire extinguishing device side when it is unfolded and covers the fire source with a second string-like member or a second net-like member of a predetermined length. The user performs operations of rolling and deploying the sheet body from the non-deployed state and moving the position of the deployed sheet body by operating the second string-like member or the second net-like member via the operation part. Also, the "second string-like member" and the "second net-like member" are of the same concept as the "first string-like member" and the "second net-like member". Also, as long as the user can perform the above-described operations via the operation part, the method of fastening the operation part to the sheet body is arbitrary.

[0053] In the following description, "the source of fire" refers to "indoor equipment and devices that can become a source of ignition", "the sheet body" refers to "when in the non-expanded state, it is wound around a shaft member with one side facing outward, and the shape of one side is rectangular", "the start and end winding portions of the sheet body" refer to "the edge of the sheet body", "the discharge port" refers to "a device provided on one side of the sheet body for discharging the fire extinguishing agent in a surface manner", "the fire extinguishing agent pipe" refers to "a flexible fire extinguishing agent supply hose", and "the fire extinguishing agent supply device" refers to "a fire extinguisher". The specific content of the embodiments of the fire extinguishing equipment will be described.

[0055] [a. Overview of Fire Extinguishing Equipment] As shown in Fig. 1, the fire extinguishing device 10 of the present embodiment is composed of a sheet body 12, a fire extinguishing agent supply hose 26 that functions as a fire extinguishing agent pipe, and a fire extinguisher 24 that functions as a fire extinguishing agent supply device. Here, Fig. 1(A) shows the overall configuration of the fire extinguishing device of the present embodiment, and Fig. 1(B) shows the left side surface of the sheet body.

[0056] In addition, the X - Y - Z directions shown in Fig. 1 are directions orthogonal to each other. When the user unfolds the sheet body towards the fire source and covers the fire source, the "one surface 12a" of the sheet body 12 becomes the "lower surface", the "end part where the sheet body ends winding" becomes the "front side edge", and the "start part where the sheet body starts winding" becomes the "rear side edge". Thus, the X direction (left - right direction), Y direction (front - rear direction), and Z direction (up - down direction) are defined. Also, the +X side in the X direction is the right side, the -X side is the left side, the +Y side in the Y direction is the front side, the -Y side is the rear side, and the +Z side in the Z direction is the upper side, the -Z side is the lower side. This is the same in Figs. 2 to 18.

[0057] [b. Sheet body] The sheet body 12 discharges the fire extinguishing agent in a surface - releasing manner to extinguish the fire in a state of being unfolded and covering the fire source. Its structure and configuration are arbitrary. As an example, it includes a fire extinguishing agent flow path 14, a fire extinguishing agent supply port 16, and a discharge port 18.

[0058] The sheet body 12 is, for example, a cloth - like body with flexibility. As shown in Fig. 1(B), with one surface 12a facing the fire source (so that one surface 12a is on the fire - source side) and covering the fire source, it extinguishes the fire by discharging the fire extinguishing agent from one surface 12a in a surface - releasing manner.

[0059] Also, the sheet body 12 is a rectangular sheet body having a one - surface 12a sized to correspond to fire - extinguishing targets including facilities, equipment, places, etc. that may become fire sources such as gas ranges and heating appliances provided in a residence or the like. For example, it is a sheet body having a square one - surface 12a. By having flexibility, in the normal non - use state, it can be in a non - unfolded state, for example, wound in a cylindrical shape, and when extinguishing a fire, it can be unfolded and used by rolling from the non - unfolded state.

[0060] (b1. Fire extinguishing agent flow path and fire extinguishing agent supply port) The fire extinguishing agent flow path 14 is a flow path for the fire extinguishing agent provided in the sheet body 12. Its structure and configuration are arbitrary. For example, a fire extinguishing agent supply port 16 is arranged at the front end side of the sheet body 12. Following the fire extinguishing agent supply port 16, a buffer area (buffer area) 20 serving as pressure buffering means shown by a dotted line inside is provided, and a fire extinguishing agent flow path 14 with a plurality of discharge ports 18 arranged at various positions on one surface 12a is provided following the buffer area 20.

[0061] The fire extinguishing agent flow path 14 is formed in a stepped shape with, for example, five steps in the front-rear direction. A buffer area 20 having a fire extinguishing agent supply port 16 is provided at the center of the first step which is the foremost step, and discharge ports 18 are arranged, for example, at four locations each from the second step to the fifth step from the front.

[0062] Further, the fire extinguishing agent flow path 14 is formed so as to supply the fire extinguishing agent from both the left and right sides of the discharge port row in the left-right direction of the discharge ports 18 arranged from the second step to the fifth step from the front. Thereby, the discharge pressure of the fire extinguishing agent supplied to the plurality of discharge ports 18 within the same row is made substantially uniform, and it is possible to make the discharge pattern (angle distribution) and the discharge amount within the same row uniform.

[0063] Note that the form of the fire extinguishing agent flow path 14 that supplies the fire extinguishing agent to the plurality of discharge ports 18 is not limited to the illustrated stepped shape, and includes appropriate forms such as a tree shape and a tournament shape. Further, in order to make the discharge pressure of the plurality of discharge ports 18 substantially uniform, the thickness (cross-sectional area) of the fire extinguishing agent flow path 14 may be made thicker on the side of the fire extinguishing agent supply port 16 and thinner as it is farther from the fire extinguishing agent supply port 16. Also, the number, position, and arrangement form of the discharge ports 18 arranged corresponding to the fire extinguishing agent flow path 14 are arbitrary.

[0064] (b2. Discharge port) The discharge port 18 is the outlet of the fire extinguishing agent supplied from the fire extinguishing agent supply port 16 to the fire extinguishing agent flow path 14. Its structure and configuration are arbitrary. For example, as shown in Fig. 1(B), it opens on one side 12a of the sheet body 12, and discharges the fire extinguishing agent supplied from the fire extinguishing agent supply port 16 to the fire extinguishing agent flow path 14 from various locations on one side 12a of the sheet body 12 to extinguish the fire.

[0065] The sheet body 12 is to be covered so as to cover the fire source with one side 12a as the lower surface (toward the fire source side) with respect to the fire source. At this time, the upper surface opposite to one side 12a becomes the other side 12b exposed to the outside.

[0066] (b3. Buffer area) When a predetermined operation is performed on the fire extinguisher 24 to open the valve, the fire extinguishing agent is to be supplied from the fire extinguisher 24 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 high-pressure fire extinguishing agent at the time of opening the fire extinguisher 24 is supplied to the fire extinguishing agent flow path 14 and the discharge port 18 of the sheet body 12, and there is a possibility that the fire extinguishing agent flow path 14 and the discharge port 18 may be damaged.

[0067] Therefore, a buffer area 20 is provided as pressure buffering means on the inlet side of the fire extinguishing agent flow path 14, and the fire extinguishing agent supplied from the fire extinguisher 24 at the initial stage after the start of fire extinguishing agent supply is temporarily retained in the buffer area 20 to adjust the increase (or increase rate) of the fire extinguishing agent pressure to a predetermined value or less, thereby preventing damage to the fire extinguishing agent flow path 14 and the discharge port 18.

[0068] [c. Fire extinguishing agent piping] The fire extinguishing agent piping is a pipe for supplying the fire extinguishing agent to the fire extinguishing agent flow path 14 of the sheet body 12. Its structure, configuration, and type are arbitrary. For example, it is a flexible fire extinguishing agent supply hose 26 made of rubber or synthetic resin.

[0069] [d. Fire extinguishing agent supply equipment] (d1. Fire extinguisher) The fire extinguishing agent supply device supplies the fire extinguishing agent to the fire extinguishing agent supply hose 26 provided as a fire extinguishing agent pipe when the user performs a predetermined operation. Its structure, function, and type are arbitrary. For example, a fire extinguisher 24 is used and connected to the other end side of the fire extinguishing agent supply hose 26. The fire extinguisher 24 is filled with a predetermined fire extinguishing agent, such as a powder fire extinguishing agent or an enhanced liquid fire extinguishing agent, in a pressure-accumulated state in the main body container. When the user pulls out the safety pin 34 and presses down the lever 35, the valve is opened, and the fire extinguishing agent is discharged from the fire extinguisher hose 25.

[0070] One end side of the fire extinguishing agent supply hose 26 is connected to the fire extinguishing agent supply port 16 of the seat body 12, and the fire extinguisher hose 25 of the fire extinguisher 24 is connected to the other end side of the fire extinguishing agent supply hose 26 via the fire extinguisher connection part 28, thereby connecting the seat body 12 and the fire extinguisher 24.

[0071] The fire extinguisher connection part 28 is composed of a fire extinguisher nozzle 30 and a fire extinguisher connection port 32. For example, a known connection joint similar to that for detachably connecting a hose to a faucet with a one-touch operation is used. Here, the fire extinguisher nozzle 30 is obtained by removing the nozzle previously attached to the tip of the fire extinguisher hose 25 of the fire extinguisher 24 and attaching a separately prepared fire extinguisher nozzle 30, but it is not limited to this.

[0072] (d2. Fire extinguisher connection part) FIG. 2 shows the fire extinguisher connection part 28 composed of the fire extinguisher nozzle 30 and the fire extinguisher connection port 32. The tip of the fire extinguisher hose 25 is provided with a dedicated fire extinguisher nozzle 30, and the other end side of the fire extinguishing agent supply hose 26 is provided with the fire extinguisher connection port 32, making the fire extinguishing agent supply hose 26 and the fire extinguisher hose 25 detachable.

[0073] The fire extinguisher nozzle 30 is connected and fixed to the fire extinguisher connection port 32 by inserting the nipple 52 with an O-ring into the opening of the fire extinguisher connection port 32. By sliding the slider 54 of the fire extinguisher connection port 32 in the direction of the illustrated arrow, the connected fire extinguisher nozzle 30 is removed.

[0074] Note that, instead of or in addition to the buffer area 20 of the sheet body 12, the fire extinguishing appliance 10 may be provided with a pressure buffer device such as an orifice that adjusts the increase (or rate of increase) in the fire extinguishing agent pressure from the fire extinguisher 24 to a predetermined level or less (to the extent that the fire extinguishing agent flow path 14 and the discharge port 18 are not damaged), for example, at the fire extinguisher connection part 28, the fire extinguishing agent supply hose 26, or the fire extinguishing agent supply port 16, etc.

[0075] [e. Manufacturing method of the sheet body 1] The sheet body 12 of the present embodiment shown in FIG. 1 is manufactured from, for example, a first cover sheet 36, a second cover sheet 38, and sheet piping 40 shown in FIG. 3. The lower surface of the first cover sheet 36 becomes one surface 12a of the sheet body 12, and the upper surface of the second cover sheet 38 becomes the other surface 12b of the sheet body 12. Note that FIG. 3 shows a state in which both cover sheets are arranged horizontally.

[0076] The first cover sheet 36 and the second cover sheet 38 are, for example, cloth-like bodies having fire resistance, fireproofness, heat resistance, or flame retardancy, and can withstand, for example, high heat of 1200°C. Those called fireproof sheets, fireproof curtains, fireproof screens, etc. can be applied, but are not limited thereto.

[0077] Also, the first cover sheet 36 and the second cover sheet 38 each have heat shielding properties, flame shielding properties, or smoke shielding properties, etc. Note that the second cover sheet 38 whose upper surface becomes the other surface 12b may be a cloth-like body that does not have fire resistance, fireproofness, heat resistance, flame retardancy, heat shielding properties, flame shielding properties, or smoke shielding properties.

[0078] The sheet piping 40 is formed by shaping a cloth-like body such as polyester used for umbrella stretching into a pipe shape and connecting it in a ladder shape (the connection part allows for flow). As shown in FIG. 4(A), it can be deformed by being crushed, and is normally flattened by being crushed. When the fire extinguishing agent 41 is supplied, it bulges as shown in FIG. 4(B) and forms the fire extinguishing agent flow path 14. The buffer area 20 provided following the fire extinguishing agent supply port 16 is also normally flattened by being crushed and bulges when the fire extinguishing agent is supplied to form the buffer area 20.

[0079] Also, as shown in FIG. 3, a plurality of discharge ports 18 are arranged in the second to fifth stage sheet pipes 40 following the first stage where the buffer area 20 is provided, and through holes 45 are opened in the first cover sheet 36 corresponding to the discharge ports 18 to be arranged.

[0080] The discharge port 18 is composed of, for example, a base 42 and a clamping ring 44 as shown in FIG. 5. A screw shaft 46 stands upright on the base 42, and a discharge hole 50 is provided penetrating the screw shaft 46. The clamping ring 44 has a screw hole 48, and the screw shaft 46 of the base 42 is screwed into the screw hole 48 to fix the base 42 and the clamping ring 44. Note that FIG. 5(A) shows the mounting state of the discharge port, FIG. 5(B) shows the exploded view of the discharge port, and FIG. 5(C) shows the exploded view of the discharge port in cross section.

[0081] As a manufacturing method, first, a first cover sheet 36 and a second cover sheet 38 of a predetermined size, and a sheet pipe 40 in the shape of a five-stage ladder are prepared.

[0082] Subsequently, as shown in FIG. 5(C), the base 42 is placed inside the sheet pipe 40, and the base 42 is adhesively fixed to the sheet pipe 40 by an adhesive portion 43 with the screw shaft 46 of the base 42 taken out from the opening provided in the sheet pipe 40. Subsequently, the screw shaft 46 taken out from the opening of the sheet pipe 40 is further taken out through the through hole 45 of the first cover sheet 36, and the screw shaft 46 is screwed into the screw hole 48 of the clamping ring 44, so that the discharge port 18 is provided in a state where the sheet pipe 40 and the first cover sheet 36 are sandwiched between the base 42 and the clamping ring 44.

[0083] Subsequently, as shown in FIG. 3, the sheet pipe 40 is arranged and overlapped so as to be sandwiched between the first cover sheet 36 and the second cover sheet 38, and the peripheral edges of the overlapped first cover sheet 36 and second cover sheet 38 are sewn by a sewing machine using an adhesive or a waterproof thread, thereby manufacturing the sheet body 12 shown in FIG. 1.

[0084] [f. Manufacturing method of sheet body 2] As another manufacturing method of the sheet body 12 of the present embodiment shown in FIG. 1, a method of manufacturing from the first cover sheet 36, the second cover sheet 38, the second waterproof sheet 58, and the second cover sheet 38 shown in FIG. 6 will be described. Note that FIG. 6 shows each sheet in a horizontally arranged state.

[0085] The first cover sheet 36 and the second cover sheet 38 are the same as those used in the manufacturing method of FIG. 3. The first waterproof sheet 56 and the second waterproof sheet 58 are made of a cloth-like body such as polyester used for umbrella stretching, similar to the sheet piping 40 used in the manufacturing method of FIG. 3. Note that the second cover sheet 38 whose upper surface becomes the other surface 12b may be a cloth-like body having no fire resistance, fireproofness, heat resistance, or flame retardancy.

[0086] Also, a fire extinguishing agent supply port 16 is arranged on the first waterproof sheet 56 corresponding to the fire extinguishing agent flow path 14 formed in the manufacturing process of the sheet body 12. A through hole 55 is formed in the first waterproof sheet 56 corresponding to the discharge port 18 arranged corresponding to the fire extinguishing agent flow path 14, and a through hole 45 is formed in the first cover sheet 36.

[0087] As shown in FIG. 7, the discharge port 18 is composed of a base 42 with a screw shaft 46 standing upright through a discharge hole 50 and a clamping ring 44 having a screw hole 48, which is the same as the form shown in FIG. 5. Note that FIG. 7(A) shows the mounting state of the discharge port, FIG. 7(B) shows the exploded view of the discharge port, and FIG. 7(C) shows the exploded view of the discharge port in cross section.

[0088] As a manufacturing method, first, prepare a first cover sheet 36, a first waterproof sheet 56, a second waterproof sheet 58, and a second cover sheet 38 of a predetermined size.

[0089] Subsequently, align the positions of the through-holes 45 and 55 of the first cover sheet 36 and the first waterproof sheet 56 and stack them. Pass the screw shaft 46 of the base 42 through the through-hole 45 of the first cover sheet 36 and the through-hole 55 of the first waterproof sheet 56 from the upper surface side of the first waterproof sheet 56 and take it out to the outside. Then, adhere and fix the base 42 to the first waterproof sheet 56 with the adhesive portion 43. Subsequently, by screwing the screw shaft 46 taken out from the through-holes 45 and 55 into the screw hole 48 of the clamping ring 44, the discharge port 18 is provided in a state where the first cover sheet 36 and the first waterproof sheet 56 are sandwiched between the base 42 and the clamping ring 44.

[0090] Subsequently, in the arrangement shown in FIG. 6, stack the first cover sheet 36, the first waterproof sheet 56, the second waterproof sheet 58, and the second cover sheet 38. In this state, as shown in FIG. 8, perform a sewing operation using, for example, a sewing machine with waterproof thread. The buffer area 20 and the fire extinguishing agent flow path 14 are formed by the sewing portion 60. Further, by integrating all the sheets with the sewing portion 61 sewn along the peripheral edge, the sheet body 12 shown in FIG. 1 is manufactured.

[0091] FIG. 9(A) shows the normal state of the fire extinguishing agent flow path 14 formed by the sewing portion 60, which is crushed and flattened. However, when the fire extinguishing agent 41 is supplied, as shown in FIG. 9(B), it swells so that the cross-sectional area increases and the fire extinguishing agent 41 can flow through. Incidentally, the buffer area 20 formed by the sewing portion 60 following the fire extinguishing agent supply port 16 is also crushed and flattened in the normal state, but swells to form the buffer area 20 when the fire extinguishing agent is supplied.

[0092] [g. Installation and Use of Fire Extinguishing Equipment] Next, the installation and use of the fire extinguishing equipment will be described in more detail.

[0093] (g1. Embodiment in Which the Sheet Body is Wound into a Cylindrical Shape) FIG. 10 is an explanatory view of an embodiment of a fire extinguishing equipment in which the sheet body is wound into a cylindrical shape in the non-expanded state. FIG. 10(A) shows the sheet body in the non-expanded state, FIG. 10(B) shows the sheet body during expansion, and FIG. 10(C) shows the sheet body after expansion.

[0094] As shown in FIG. 10(A), the sheet body 12 of the present embodiment is arranged in a non-expanded state normally wound around the shaft member 70 in a cylindrical shape. The shaft member 70 can have any structure and material as long as it can wind the sheet body 12. For example, it is a hollow cylindrical body having a length exceeding the width (left-right direction) of the sheet body 12, and is formed of an appropriate material such as paper, resin, or light metal.

[0095] Also, the diameter of the shaft member 70 is arbitrary, but in order to suppress deformation due to winding of the sheet body 12 and to make it easy for the user to roll and deploy the non-expanded sheet body 12, it is, for example, about 10 cm. When the outer diameter of the shaft member 70 is 10 cm, the length per one winding of the sheet body 12 is about 30 cm. If the length of the sheet body 12 is, for example, 1 m, the number of windings of the sheet body 12 around the shaft member 70 is about 3 windings. If the thickness of the sheet body 12 is, for example, 1 cm, the outer diameter of the shaft member 70 around which the sheet body 12 is wound is about 16 cm, and it becomes a size that anyone can easily handle the non-expanded sheet body 12. Note that the shaft member 70 is not limited to a hollow shaft member, and may be solid or a polygonal prism instead of a cylinder, and an appropriate structure is selected.

[0096] The winding of the sheet body 12 using the shaft member 70 is performed so that one surface 12a of the sheet body 12 provided with the discharge port 18 shown in FIG. 1 faces outward. That is, as shown in FIG. 10(C), from the expanded state with one surface 12a of the sheet body 12 as the lower surface (the back surface not visible in the figure), as shown in FIGS. 10(B) and 10(A), from the rear end side (starting part of winding) of the sheet body 12 to the front end side (ending part of winding) where the fire extinguishing agent supply port 16 to which the fire extinguishing agent supply hose 26 is connected is arranged, the shaft member 70 is rotated to wind the sheet body 12 into a non-expanded state.

[0097] Then, the sheet body 12 wound around the shaft member 70 is stored and arranged in a storage section as shown in, for example, FIG. 11. Here, FIG. 11(A) shows the arrangement state of the fire extinguisher including components other than the sheet body in appearance, and FIG. 11(B) shows the arrangement portion of the sheet body in cross section.

[0098] As shown in FIG. 11, a pedestal 72 is provided in the storage section, a cylindrical holder 74 is arranged on the pedestal 72, and a support pole 84 stands upright at the center of the holder 74. By fitting the hollow portion of the shaft member 70 onto the support pole 84, the sheet body 12 wound around the shaft member 70 is held upright by the holder 74. A cylindrical cap 76 with its upper part closed is detachably attached to the upper part of the upright sheet body 12 to hold the sheet body 12 wound around the shaft member 70 in a non-expanded state. Also, with the inner diameter of the holder 74 being a diameter capable of holding the sheet body 12 in a non-expanded state, the sheet body 12 may be held in a non-expanded state by only the holder 74 without attaching the cap 76.

[0099] Further, a fire extinguisher 24 is arranged in the fire extinguisher holder 78 of the pedestal 72, and the fire extinguisher hose 25 is connected to a fire extinguishing agent supply hose 26 connected to the fire extinguishing agent supply port 16 of the sheet body 12 by a fire extinguisher connection portion 28. The fire extinguishing agent supply hose 26 is arranged in a state of being wound around a hose holder 82 formed on a pole 80 of the pedestal 72.

[0100] Regarding the arrangement of the fire extinguisher during normal times and its use in the event of a fire, taking the case where a sofa placed in a smoking area or the like is the object to be extinguished as an example, it will be described in more detail with reference to FIG. 12. As shown in FIG. 12(A), for example, during normal times, the non-expanded sheet body 12 is arranged in an upright state in the holder 74 of the pedestal 72 installed in front of the sofa 64, as shown in FIG. 11.

[0101] As shown in Fig. 12(B), when a fire occurs at the ignition source 66 due to the remaining fire of smoking or the like on the sofa 64, the user 68 removes the cap 76 from the seat body 12 standing on the holder 74 of the pedestal 72 and takes out the seat body 12 from the holder 74. Subsequently, with the user 98 holding the front end side (the end of the winding) of the seat body 12 in the non-expanded state, as shown in Fig. 12(C), the seat body 12 is thrown toward the ignition source 66 of the sofa 64 to roll the seat body 12. In this case, for throwing out the seat body 12, there is a method of underhand throwing while holding both ends of the front end side of the seat body 12, for example, but any appropriate throwing method may be used as long as the seat body 12 can be rolled and deployed.

[0102] As the seat body 12 is thrown toward the ignition source 66, the seat body 12 unfolds while rolling together with the shaft member 70, and as shown in Fig. 12(D), the seat body 12 unfolds with one surface 12a on the lower side to cover the fire source of the sofa 64 including the ignition source 66. Also, the shaft member 70 detaches from the seat body 12 after the seat body 12 is deployed and rolls away.

[0103] After covering the fire source by deploying the seat 12, when the user 68 performs an operation of pulling out the safety pin 34 of the fire extinguisher 24 arranged on the pedestal 72 and pressing down the lever 35 to open the valve, the fire extinguishing agent is supplied from the fire extinguisher 24 to the fire extinguishing agent supply port 16 of the seat body 12 through the fire extinguisher hose 25 and the fire extinguishing agent supply hose 26, and the fire extinguishing agent is discharged in a surface manner from the discharge ports 18 provided at various positions on the one surface 12a which is the lower surface of the seat body 12, so that the fire extinguishing agent evenly spreads over the fire source covered by the seat body 12, enabling effective fire extinguishing in a short time.

[0104] When throwing out and rolling the seat body 12 wound around the shaft member 70 in this way, the seat body 12 rotates quickly under the inertial force of the shaft member 70, and there is no need for a special way of holding or throwing for the operation of deploying the seat body 12 by the user 98, so the seat body 12 can be easily and more reliably placed over the fire source of the sofa 64.

[0105] In addition, instead of throwing out the sheet body 12, the sheet body 12 in the undeveloped state may be positioned in front of the sofa 64, and both ends of the front end side of the sheet body 12 may be lifted up high. By lifting the front end side of the sheet body 12 in this way, the sheet body 12 can also be rolled toward the fire source, and the sheet 12 can be easily and more surely covered over the fire source. Further, a mechanism for holding the front end side of the sheet body 12 in the undeveloped state in a direction in which the sheet body 12 can be deployed toward the fire source may be provided on the pedestal 72 to assist the user in deploying the sheet body 12. Thereby, since the position of the front end side of the sheet body 12 in the undeveloped state is fixed, the area for deploying and covering the sheet body 12 is determined, and it is possible to suppress the deployed sheet body 12 from being displaced with respect to the fire source, and the sheet body 12 can be more surely covered over the fire source.

[0106] (g2. Embodiment in which a shaft member is attached to a sheet body by a suspension string) An embodiment of a fire extinguishing device in which a sheet body and a shaft member are mutually attached by a suspension string will be described in more detail. Here, the "suspension string" corresponds to the "first string-shaped member".

[0107] In this embodiment, as shown in FIG. 13(A), the shaft member 70 is attached to both ends of the rear end side of the sheet body 12 by suspension strings 88 having a predetermined length. Here, the length of the suspension string 88 is arbitrary, but for example, it is set to a length of about 20 to 30 cm, and the suspension string 88 is a string formed by bundling fibers made of a material having fire resistance, heat resistance, or flame retardancy.

[0108] FIG. 14 shows the shaft member of FIG. 13 taken out. FIG. 14(A) shows a cross section in the axial direction, FIG. 14(B) shows a cross section taken along line a-a of FIG. 14(A), and FIG. 14(C) shows a cross section taken along line b-b of FIG. 14(A).

[0109] As shown in FIG. 14, a cylindrical hole 702 is formed axially in a shaft member body 700 of the shaft member 70, and annular weights 92 are disposed at both ends and in the center of the cylindrical hole 702. Further, a suspension string 88 is passed from the outside to the inside through a through hole 96 formed in the shaft member body 700, and a fastener 94 having a size that does not pass through the through hole 96 is tied to the tip of the suspension string 88 passed through the inside to prevent it from coming off, whereby the shaft member 70 is fastened to the seat 12 by the suspension string 88.

[0110] In this way, with the shaft member 70 fastened to both ends of the rear end side (starting winding portion) of the seat body 12 by the suspension string 88, the seat body 12 is wound around the shaft member 70 in a cylindrical shape, and normally, it is erected and arranged on the holder 74 of the pedestal 72.

[0111] Regarding the use during a fire, it is almost the same as the example shown in FIG. 12. However, even after the seat body 12 is deployed, the shaft member 70 does not separate from the seat body 12, and it rolls while pulling the seat body 12 to assist in the deployment of the seat body 12, and then functions as a weight to stably maintain the deployed state of the seat body 12.

[0112] For example, as shown in FIG. 13(B), by rolling the non-deployed seat body 12 toward the fire extinguishing target 90, the seat body 12 is deployed and covers the fire extinguishing target 90. At this time, the shaft member 700 rolls while pulling the seat body 12 to the rear side of the seat body 12 during the deployment of the seat body 12 to assist in the deployment of the seat body 12, and after the deployment of the seat body 12, it is suspended by the suspension string 88 at the rear end side (starting winding portion) of the seat body 1200 and functions as a weight. Therefore, even if a fire extinguishing agent is released onto the fire source covered by the seat body 12, the weight of the shaft member 70 in the suspended state by the suspension string 88 suppresses the lifting of the deployed seat body 1200, suppresses the leakage and scattering of the fire extinguishing agent from the space covered by the seat body 1200, enhances the fire extinguishing effect, and reduces the contamination of the surroundings. Note that even when the shaft member 70 is in contact with the floor or the like, the seat body 12 functions as a weight, so it is not always necessary for the shaft member 70 to be suspended with respect to the seat body 12 after the deployment of the seat body 12.

[0113] (Embodiment in which a handle is attached to a sheet body by an operating string) An embodiment of a fire extinguisher in which a handle is attached to a sheet body by an operating string will be described in more detail with reference to FIG. 15. Here, the "handle" corresponds to the "operating part", and the "operating string" corresponds to the "second string-shaped member". FIG. 15(A) shows the sheet body in the non-expanded state, FIG. 15(B) shows the sheet body during expansion, and FIG. 15(C) shows the sheet body after expansion.

[0114] In this embodiment, as shown in FIG. 15, the handle 102 is handheld and is attached to both ends of the front end side (winding end portion) of the sheet body 12 by an operating string 100 of a predetermined length. Here, the length of the operating string 100 is arbitrary, but the length of the operating string 100 is determined so that the distance from the handle 102 to the sheet body 12 is, for example, in the range of about 1 to 2 m to such an extent that a user holding the handle can keep a safe distance from the fire source. Further, the operating string 100 may be a string formed by bundling fibers made of a material having fire resistance, heat resistance, or flame retardancy, similar to the suspension string 88.

[0115] The structure and material of the handle 102 are arbitrary. For example, it is a plate member formed of an appropriate material such as resin or light metal. There is an operation opening 104 for a user to put their hand in and hold the handle 102, and a through hole 106 for passing the fire extinguishing agent supply hose 26 is provided to restrict the movement of the fire extinguishing agent supply hose 26 so that the fire extinguishing agent supply hose 26 does not interfere with a user handling the fire extinguisher.

[0116] The sheet body 12 to which the handle 102 is attached by the operating string 100 is, as shown in FIG. 16, arranged upright on the holder 74 of the pedestal 72 in a state where the operating string 100 and the fire extinguishing agent supply hose 26 passed through the through hole 106 of the handle 102 are wound around the outside of the sheet body 12 wound cylindrically around the shaft member 70. Note that FIG. 16(A) shows the upper surface of the sheet body in the non-expanded state, and FIG. 16(B) shows the left side surface.

[0117] Regarding the use in case of a fire, it is almost the same as the example shown in Fig. 12. However, the user will hold the handle 102 attached to the sheet body 12 taken out from the holder 74 of the pedestal 72 with one hand and throw out the sheet body 12 with the other hand. Also, the sheet body 12 can be thrown out at a location additionally away from the fire source by the distance from the handle 102 to the sheet body 12, ensuring the safety of the user.

[0118] The deployment of the sheet body 12 using the operation part is a deployment with the user holding the position of the handle 102. First, as shown in Fig. 15(A), the operation string 100 and the fire extinguishing agent supply hose 26 wound around the outside of the sheet body 12 are unwound. Subsequently, as shown in Fig. 15(B), the sheet body 12 is deployed. Finally, as shown in Fig. 15(C), the sheet body 12 is deployed to cover the fire source, and the shaft member 70 detaches from the sheet body 12. Also, although the handle 102 is attached, the sheet body 12 can be deployed by rolling the sheet body 12 in the same way as when not having the handle 102. Since there is no need for a special way of holding or throwing for the operation of deploying the sheet body 12 by the user 98, the sheet body 12 can be easily, more reliably, and safely covered over the fire source.

[0119] Also, when throwing out the sheet body 12 towards the fire source, for example, by operating the operation string 100 through an operation such as pulling the handle 102 forward, it is possible to apply a rotational force to the sheet body 12 during deployment and make it roll more quickly, enabling the sheet body 12 to be deployed more quickly. Also, when the deployed sheet body 12 goes too far (to the rear side) relative to the fire source, for example, by pulling the handle 102 forward (to the front side), it is possible to adjust the deployed sheet body 12 to an appropriate position relative to the fire source, or to pull the sheet body 12 to the user's hand, recover and rewind it to make the sheet body 12 in a non-deployed state, and then throw out the sheet body 12 towards the fire source again.

[0120] In addition, since the fire extinguishing agent supply hose 26 drawn from the sheet body 12 passes through the through hole 106 of the handle 102, the movement of the fire extinguishing agent supply hose 26 is restricted when the sheet body 12 is deployed, so that the fire extinguishing agent supply hose 26 does not interfere with the user handling the fire extinguishing equipment.

[0121] (g4. Embodiment in which a shaft member and a handle are attached to a sheet body) Alternatively, it may be a sheet body that combines the "g2. Embodiment in which a shaft member is attached to a sheet body by a suspension string" and the "g3. Embodiment in which a handle is attached to a sheet body by an operation string".

[0122] In this embodiment, as shown in Fig. 17(A), handles 102 are attached to both ends of the front end side of the sheet body 12 by operation strings 100, and shaft members 70 are attached to both ends of the rear end side of the sheet body 12 by suspension strings 88 of a predetermined length. The shaft members 70 and the suspension strings 88 are the same as those shown in Figs. 13 and 14, and the handles 102 and the operation strings 100 are the same as those shown in Fig. 15.

[0123] Regarding the use in the event of a fire, it is a combination of the descriptions of the "g2. Embodiment in which a shaft member is attached to a sheet body by a suspension string" and the "g3. Embodiment in which a handle is attached to a sheet body by an operation string".

[0124] In addition, this embodiment has the effects of both the case where the shaft member 70 is attached by the suspension string 88 and the case where the handle 102 is attached by the operation string 100.

[0125] (g5. Another form of the shaft member) Another embodiment of the shaft member 70 around which the sheet body 12 is wound will be described in more detail. Fig. 18(A) shows another embodiment of the shaft member 70, in which flanges 704 are provided at both ends of a hollow shaft member body 700 having a cylindrical hole 702, and the axial length of the shaft member body 700 corresponds to the width of the sheet body 12. The diameter of the flange 704 is set to be larger than the outer diameter of the sheet body 12 when the sheet body 12 is wound around the shaft member body 700 in a cylindrical shape.

[0126] By providing the flanges 704 at both ends of the shaft member body 700 in this way, when the sheet body 12 is wound around the shaft member body 700, the winding position of the sheet body 12 is restricted by the flanges 704 at both ends of the shaft member body 700, facilitating the winding of the sheet body 12 around the shaft member 70. Also, when the non-deployed sheet body 12 is thrown towards the fire source during a fire, after the deployed sheet body 12 has fallen onto the surface of the object to be extinguished or the ground, etc., the flange 704 acts as a wheel to assist in the deployment of the sheet body 12 by rolling, so that the sheet body 12 can be rolled and deployed more quickly. The effect of the flange body 704 acting as a wheel is effectively exerted when the object to be extinguished is planar.

[0127] FIG. 18(B) shows another embodiment of the shaft member 70 different from FIG. 18(A). In the shaft member 70 of this embodiment, flanges 704 similar to those in FIG. 18(A) are provided at intervals corresponding to the width of the sheet body 12 on both sides of the shaft member body 700, and an exposed shaft portion 706 having the same diameter as the shaft member body 700 is coaxially provided outside the flange 704.

[0128] By providing the exposed shaft portion 706 outside the flange 704 in this way, when the sheet body 12 is wound around the shaft member body 700, by rotating the exposed shaft portion 706, it becomes possible to easily perform the winding operation of the sheet body 12, or it becomes possible to use the exposed shaft portion 706 as a handle during transportation work, etc. Note that a weight 92 may be provided in the cylindrical hole 702 of the shaft member 70 in FIGS. 18(A) and (B) as in the shaft member shown in FIG. 14.

[0129] [h. Embodiment in which a position adjustment string is provided on the sheet body] An embodiment of a fire extinguishing device provided with a position adjustment string for adjusting the position after the sheet body is deployed will be described in more detail with reference to FIG. 19. Here, the "position adjustment string" corresponds to the "third string-like member".

[0130] As shown in FIG. 19, the fire extinguishing device of the present embodiment, similar to that shown in FIG. 17, attaches the handle 102 to both ends of the front end side of the sheet body 12 by the operation string 100, and attaches the shaft member 70 to both ends of the rear end side of the sheet body 12 by the suspension string 88.

[0131] In addition to this, in the present embodiment, one end of the position adjustment string 110 is provided at each of the four end portions of the sheet body 12, and the knob 112 is attached to the other end of the position adjustment string 110. Further, the position adjustment string 110 is made of a material having fire resistance, heat resistance or flame retardancy. Also, the shape of the knob 112 is arbitrary, for example, spherical, and by being connected to the sheet body 12 via the position adjustment string 110 after the sheet body 12 is unfolded, it has a function as a weight located around the sheet body 12.

[0132] The position of the sheet body 12 where the position adjustment string 110 is provided and the length of the position adjustment string 110 are arbitrary, but for example, it is a length that allows the user to operate the position adjustment string 110 from a safe position away from the fire source in a state where the sheet body 12 is unfolded to cover the fire source, and is set to a length exceeding the vertical width (front-rear direction) of the sheet body 12.

[0133] When the sheet body 12 is wound around the shaft member 70 to form a cylindrical shape, the position adjustment string 110 is arranged on the other surface 12b side of the sheet body 12 so as to be substantially in the axial direction of the shaft member 70, like the position adjustment string 1100 shown by the dotted line, and in this state, the sheet body 12 is wound around the shaft member 70 in a cylindrical shape.

[0134] An example of using a fire extinguisher with a position adjustment string 110 attached to a sheet body 12 will be described in more detail with reference to FIG. 20. FIG. 20(A) shows a state where the sheet body 12 is deployed toward the fire target object 90 that is the source of the fire, but the sheet body 12 is deployed at a position deviated from the fire target object 90 and is not properly covered to cover the fire target object 90. Further, the position adjustment string 110 attached to the end of the sheet body 12 has one end attached to the sheet body 12 as a fulcrum, and the knob 112 attached to the other end functions as a weight, so that when the user throws the sheet body 12 toward the fire source, it receives the action of the force applied to the sheet body 12 and jumps out toward the outside together with the knob 112 from the sheet body 12 during the deployment of the sheet body 12. As a result, as shown in FIG. 20(A), after the sheet body 12 is deployed, the position adjustment string 110 and the knob 112 are located around the deployed sheet body 12.

[0135] Further, the position adjustment string 110 to which the knob 112 functioning as a weight is attached assists in the deployment when the sheet body 12 is deployed by the knob 112 and suppresses the lifting of the sheet body 12 after the deployment. Thereby, the sheet body 12 can be deployed more smoothly and continuously and stably cover the fire source. Furthermore, it is possible to suppress the leakage and scattering of the fire extinguishing agent from the fire source covered by the sheet body 12, enhance the fire extinguishing effect, and reduce the contamination of the surroundings.

[0136] And when the sheet body 12 is deployed at a position deviated from the fire target object 90 in this way, as shown in FIG. 20(B), the user can perform an operation of pulling, in the direction indicated by the arrow, two position adjustment strings 110 located, for example, on the right side of the sheet body 12 among the position adjustment strings 110 attached to the end of the deployed sheet body 12, and move the sheet body 12 to an appropriate position to cover the fire target object 90. Note that the position adjustment string 110 attached to the sheet body 12 only needs to be able to adjust the position of the deployed sheet body 12, and the position and the number of the position adjustment strings 110 attached to the sheet body 12 are arbitrary.

[0137] [i. Embodiment in which a shaft member and a handle are attached to a sheet body by a net] An embodiment of a fire extinguisher in which a shaft member and a handle are bound to a sheet body by a net will be described in more detail with reference to FIG. 21. Here, the "net" for binding the shaft member corresponds to the "first net member", and the "net" for binding the handle corresponds to the "second net member".

[0138] As shown in FIG. 21, the fire extinguisher of this embodiment includes a sheet body 12, a shaft member 70, and a handle 102, similar to the embodiment of FIG. 17. However, the rear end edge of the sheet body 12 and the shaft member 70 are bound to each other by a suspension net 120, and the front end edge of the sheet body 12 and the handle 102 are bound to each other by an operation net 130. Here, the shape of the suspension net 120 and the operation net 130 can be arbitrary as long as they can be wound around the shaft member 70 in the same manner as the sheet body 12. However, the suspension net 120 is rectangular, and the operation net 130 is triangular with the front end edge of the sheet body 12 as the base and the handle 102 side as the apex.

[0139] In addition, the suspension net 120 and the operation net 130 are made of a fire-resistant, heat-resistant, or flame-retardant material, and the mesh shape can be arbitrary, but for example, it is rectangular. Also, the size of the mesh unit opening can be arbitrary, but for example, it is about several centimeters in length and width to enhance flexibility.

[0140] By binding the sheet body 12 and the shaft member 70 with the suspension net 120 in this way, the suspension net 120 becomes flush with the sheet body 12. Therefore, compared with the suspension string 88 in FIG. 17, it is easier to wind around the shaft member 70, and subsequently, it is also easier to wind the sheet body 12.

[0141] Also, by binding the sheet body 12 and the handle 102 with the operation net 130, the operation net 130 becomes flush with the sheet body 12, similar to the suspension net 120, making it possible to easily wind the operation net 130 compared with the operation string 100 in FIG. 17.

[0142] [j. Embodiment in which weights are provided on the front and rear end edges of the sheet body] Another embodiment of the fire extinguishing device with weights provided at the front and rear edges of the sheet body will be described in more detail with reference to FIG. 22.

[0143] FIG. 22(A) shows another embodiment of the sheet body produced by the procedure shown in FIG. 3. In the non-deployed state, the sheet body 12 of this embodiment is wound around the shaft member 70 in the front-rear direction to form a cylindrical shape, and a plurality of weights 22 are arranged at intervals between the front edge 13a and the rear edge 13b that do not deform when wound around the shaft member 70.

[0144] The arrangement structure of the weights 22 is arbitrary. For example, when overlapping the first cover sheet 36 and the second cover sheet 38 shown in FIG. 3, the weights 22 are arranged 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 adhered or sewn by a sewing machine using waterproof thread corresponding to the arranged position, thereby fixing the weights 22 along the front edge 13a and the rear edge 13b. Also, the shape of the weights 22 is arbitrary, for example, a member such as lead of a predetermined length. On the other hand, no weights are arranged on the right edge 13c and the left edge 13d of the sheet body 12 so as not to interfere with winding around the shaft member 70, but if flexible weights 22 are used, the weights 22 may be arranged on the right edge 13c and the left edge 13d.

[0145] When the sheet body 12 wound in a cylindrical shape is rolled out to cover the fire source, the weights 22 assist the unfolding itself, and after unfolding, they hold down the front edge 13a and the rear edge 13b of the sheet body 12 (suppressing unnecessary movement) to suppress the lifting of the sheet body 12 due to the discharge of the fire extinguishing agent. As a result, the sheet can be smoothly unfolded and continuously and stably cover the fire source, and further, the leakage and scattering of the fire extinguishing agent from the fire source covered by the sheet body 12 can be suppressed to enhance the fire extinguishing effect and reduce the pollution of the surroundings.

[0146] FIG. 22(B) shows another embodiment of the sheet body produced by the procedure shown in FIG. 6. The sheet body 12 of this embodiment is also the same as the sheet body 12 in FIG. 22(A). A plurality of weights 22 are arranged at intervals on the front end side 13a and the rear end side 13b of the sheet body 12, and the weights 22 have the same effect as the weights 22 of the sheet body 12 in FIG. 22(A).

[0147] [i. Modifications of the present invention] (Application target) In the above embodiment, as the fire extinguishing target of the fire extinguishing equipment, the fire extinguishing targets such as facilities, equipment, and places that may become the source of fire in a dwelling are taken as examples. However, further, for example, it can be applied to fire extinguishing targets such as facilities, equipment, and places that may become the source of fire in factories, schools, government offices, warehouses, and other appropriate facilities.

[0148] (Sheet body) In the above embodiment, the case where the shape of the sheet body is rectangular is taken as an example, but it is not limited to this. For example, it may be circular, elliptical, polygonal other than rectangular, or a combination of these shapes corresponding to the fire extinguishing target. Further, in the above embodiment, weights are arranged along the front end side 13a and the rear end side 13b of the sheet body, but it is not limited to this.

[0149] (Fire extinguishing agent flow path) In the above embodiment, the fire extinguishing agent flow path 14 is formed by using sheet piping or sewing or bonding with a sewing machine using a waterproof thread, etc., but the formation of the fire extinguishing agent flow path is not limited to this. For example, a fire extinguishing agent flow path using a tube made of resin or the like may be used.

[0150] (Fire extinguishing agent supply equipment) In the above embodiment, a fire extinguisher is taken as an example of the fire extinguishing agent supply equipment, but it is not limited to this and is arbitrary, and various portable fire extinguishing agent supply equipment can be used. For example, a simple pressure accumulator water supply pump or the like may be used. The pressure accumulator water supply pump accommodates the fire extinguishing agent in a container, compresses the air in the container by manual operation, and supplies and discharges the fire extinguishing agent to the sheet body by the compressed air.

[0151] (Others) In addition, the present invention includes appropriate modifications that do not impair its objects and advantages, and is not limited by the numerical values shown in the above embodiments.
