Description

  The present invention relates to a fire extinguisher used for initial fire extinguishing in a kitchen fire such as a gas stove stand.

DESCRIPTION OF RELATED ART Conventionally, the fire extinguishing sheet utilized for the initial fire extinguishing in kitchen fires, such as a gas stove stand (stove stand), is known (for example, refer patent document 1). Such a fire extinguishing sheet, as described in Patent Document 1, (1) has fire resistance and non-flammability, (2) does not generate a gap between the stove stand and the like when covered, (3) It is required that the eyes are clogged so that air does not enter, and that (4) there is no oil penetration. From such a point of view, Patent Document 1 discloses a kitchen fire extinguishing cloth in which a glass fiber woven fabric is heat-cleaned to remove organic substances and a fluororesin and a silicone resin are coated thereon.
In addition, as a fire extinguisher using a fire extinguishing cloth, wrap the glass fiber cloth small like a squeezed towel so that the folded glass fiber woven cloth can be used immediately at the time of use so that it becomes a furoshiki shape, One that spreads by its own weight and extinguishes fire by placing it on a stove stand or the like in the event of a fire is known (for example, see Patent Document 2).
In addition, about the fire extinguishing cloth like patent document 1 or 2, the test report with respect to a product is also made (refer nonpatent literature 1).
Furthermore, as a fire extinguisher (fire extinguishing device), prepare a fireproof sheet by winding it around one side in the longitudinal direction of the stove base, expand the fireproof sheet in the event of a fire, and rewind it on the other side in the longitudinal direction of the stove base. There are also known coverings (see, for example, Patent Document 3).

The upper wheel 6 has a hollow shape having a flange 6b and a hollow portion 6c. Here, the upper wheel 6 is engaged (fixed) with the hollow fixing member 5 having the upper flange 5a and the lower flange 5b, for example, by screwing or the like. Further, the end 1 a of the seat 1 is sandwiched between the lower flange 5 b of the fixing member 5 and the flange 6 b of the upper wheel 6. In addition, if the substantially center part of the sheet | seat 1 can be firmly fixed only by the upper wheel 6, the structure which abbreviate | omits the fixing member 5 and provides an upper flange in the upper wheel 6 may be sufficient.
The lower wheel 4 includes a cylindrical body 4b, and the holding member 7 described above is provided on a side surface of the cylindrical body 4b having a predetermined height. The holding member 7 is provided so as to be able to appear and retract so as to hold the fire extinguishing tool 10 in an unfolded state by engaging with the upper flange 5a of the fixing member 5 (and the upper surface of the upper potter's wheel 6). In this way, the holding member 7 functions as a locking member because it locks the upper wheel 6 and the lower wheel 4 when the fire extinguishing unit 10 is held in the deployed state.
Further, at the end of the cylindrical body 4b of the lower wheel 4, when the lower wheel 4 is moved upward, that is, when the fire extinguisher 10 is deformed to the expanded state, the lower wheel 4 is pulled toward the upper wheel 6 side. A tension member 8 is provided. Here, the cylindrical body 4 b can slide in the hollow portion 6 c of the upper wheel 6. Note that one end of the tension member 8 may be directly connected to the upper flange of the lower wheel 4. In this case, the cylindrical body 4 b is not necessary, but the holding member 7 may be provided at a predetermined position of the tension member 8.
On the other end side of the tension member 8, as shown in FIG. 1, a hook portion 9 for hooking the fire extinguishing tool 10 on a wall hook or the like is provided. The fire extinguisher 10 has a notebook-type structure as described above, and can be folded by separating the lower potter 4 from the upper potter 6, so that it can be stored compactly by using the hook 9. it can.
The fire extinguishing tool 10 of the present invention has such a configuration, and after the user holds the expanded state by the holding member 7 by pulling the tensile member 8, the tensile member 8 is supported in the expanded state. Since the entire fire extinguishing tool 10 can be firmly supported, as will be described later, when using the fire extinguishing tool 10 for the initial fire extinguishing on the stove stand, etc., it is effective without the user being burned. Can be used.

In addition, although the method of engaging each parent bone 2 and the upper wheel 6 is not particularly limited, in the present embodiment, the engaging member 6a is, for example, a wire wound around the upper wheel 6, and the wire. Is passed through a hole provided at one end of each of the main bones 2, so that each of the main bones 2 can be rotatably engaged with the upper potter's wheel 6.
Similarly, although the method of engaging each support frame 3 and the lower wheel 4 is not particularly limited, in this embodiment, the engaging member 4a is, for example, a wire wound around the lower flange or the like of the lower wheel 4 By passing this wire through a hole provided at one end of each support frame 3, each support frame 3 can be rotatably engaged with the lower potter's wheel 4.
Moreover, the tension | tensile_strength member 8 used for the fire extinguisher 10 of this invention will not be specifically limited if it can support the fire extinguisher 10 whole state of an expansion | deployment state. For example, as shown in FIG. 1, the tension member 8 is a solid metal wire or metal rod having rigidity sufficient to support the entire fire extinguishing tool 10, or a hollow metal rod (sliding folding type like an umbrella). Or the like can be used. As long as the entire fire extinguishing tool 10 can be supported in this way, the connecting portion of the tubular body 4b and the tension member 8 may be bent and fixed in that state.

Moreover, the sheet | seat 1 used for the fire extinguisher 10 of this invention will not be specifically limited if it has heat resistance as a fire extinguishing sheet. For example, any one of glass fiber, carbon fiber, ceramic fiber, metal fiber, aramid fiber or the like, or a woven fabric using two or more kinds in combination can be used. In particular, the sheet 1 is preferably a high silicate glass fiber woven fabric that is sealed with an acrylic resin or a silicone resin so as not to deteriorate the oxygen blocking performance due to misalignment. In the case of such a woven fabric, the fire extinguishing tool 10 can be used a plurality of times because it is lightweight, has high strength and durability, and is less likely to cause thermal deformation, thermal breakage, and the like.
In order to further improve the oxygen blocking performance, after performing the sealing treatment, an adhesion treatment for adhering a flame retardant urethane resin, a fluorine resin, or the like may be performed.
Moreover, the main frame 2 and the support frame 3 used for the fire extinguishing tool 10 of the present invention can be made of ceramic or metal excellent in heat resistance. When the main bone 2 and the support frame 3 are made of metal, there is no thermal deformation or heat damage. For example, if the sheet 1 is a disposable fire-extinguishing sheet, the main bone 2 and the support frame 3 should be used multiple times. Can do.
In this case, the disposable fire extinguishing sheet includes, for example, a highly heat-resistant resin, and as such a resin, a phenol resin, an epoxy resin, a polyester resin, a polyamide resin, a polycarbonate resin, and the like are mixed with glass fiber. Fiber reinforced resin can be used.

As described above, the folding book structure used in the present invention fixes a member that stretches the sheet 1 (such as the main bone 2), a member that expands (expands) the sheet 1 (such as the tension member 8), and the expanded sheet. There is no particular limitation as long as it has a member (such as holding member 7) and a member (such as tension member 8) that opens the developed sheet. For example, the structures disclosed in FIG. 2 and FIG. 3 of Japanese Utility Model Publication No. 55-7170, FIG. 1 of Japanese Utility Model Publication No. 6-41492, FIG. 3 of Japanese Utility Model No. 3038471, etc. can be used.
In addition, such a grid-type structure preferably has a rectangular opening in the unfolded state since the planar shape of the stove base (especially, the stove base having three stovetops) is rectangular, but it is limited to this. Without limitation, the shape of the opening may be circular, polygonal, or the like. In this case, the numbers of the main bone 2 and the supporting bone 3 may be appropriately determined according to the shape of the opening.

Next, an embodiment of a method for using the fire extinguisher 10 of the present invention will be described with reference to FIG.
The fire extinguisher 10 of the present invention is hung on the hook 31 attached to the vicinity of the gas stand 20, for example, the wall 30, via the hook portion 9 (see FIG. 4A). In addition, it is not preferable to install in the storage cupboard etc. under the gas stand 20, since it is too close to the fire source when a fire occurs.
When a fire has occurred from a tempura pan or the like on the stove stand, remove the fire extinguishing tool 10 from the hook 31, hold the tension member 8 or the catch 9 with the user's dominant hand, hold the fixing member 5 with the opposite hand, The opening side of the sheet 1 is directed to the fire source (see FIG. 4B).
Then, the fixing member 5 is fixed with the reverse hand, the pulling member 8 is pulled with the dominant hand, the fire extinguishing tool 10 is deployed, the holding member 7 and the upper flange 5a of the fixing member 5 are engaged, and the seat 1 is The unfolded state of the fire extinguishing tool 10 is maintained so as to be a notebook type. Then, with the fire extinguisher 10 supported by the tension member 8, the fire extinguisher 10 is oriented obliquely so as to be vertical to the fire source, and the lower end of the fire extinguisher 10 (one end) is placed in front of the stove stand 20 (one end). One end side is brought into contact (see FIG. 4C).
And the other end side of the fire extinguishing tool 10 is brought into contact with the stove stand 20 so that the entire lower part of the fire extinguishing tool 10 (that is, the edge of the sheet 1) is brought into contact with the stove stand 20, and the stove (in particular, After confirming that the fire-extinguishing stove is covered with the fire extinguishing tool 10, release the hand from the tension member 8 and put the fire extinguishing tool 10 on the stove table 20 (see FIG. 4D).
Even if the fire flame is initially extinguished, there is a possibility of reignition if air (oxygen) is supplied for several tens of minutes. Therefore, it is necessary to leave the fire extinguisher 10 as it is.
As described above, by using the fire extinguishing tool 10 of the present invention, it is possible to appropriately perform initial fire fighting against a fire such as a tempura pan while further reducing the risk of a user being burned.

  As mentioned above, although the fire extinguisher of this invention was demonstrated with reference to the accompanying drawing, this invention is not limited to the structure of each above-mentioned embodiment. Each part which comprises the fire extinguisher of this invention can be substituted with the thing of the arbitrary structures which can exhibit the same function. Moreover, arbitrary components may be added to the fire extinguisher of the present invention.

Using 75 1/0 0.7Z E-glass yarn, acid processing was applied to a base of 4 satin weaves with a density of 53 / 25mm and a weft of 51 / 25mm. The agent was removed, and a high silicate silica fiber woven fabric of 96% SiO ₂ was produced. Next, 2% impregnation treatment was applied to 100% high-silica silica fiber woven fabric as a sealing agent, and a fire extinguishing sheet was prepared.
Each member as described above was prepared and a fire extinguisher was prepared so that the fire extinguishing sheet had a checkered structure shown in FIGS.

Next, 1.0 liter of salad oil is put in an aluminum two-handed pan having a diameter of 20 cm and a capacity of 2.75 liters, heated on a gas stove table, and ignited when the oil temperature reaches 350 ° C. After the passage, when the pan was covered with the fire extinguisher prepared as described above, it was possible to extinguish the fire in about 14 seconds (spreading: 3 seconds, covering: 1 second, fire extinguishing: 10 seconds).
In this embodiment, the fire extinguisher can be expanded into a notebook type with a single touch, and even if it is expanded into a notebook type, the fire extinguisher can be placed on the stove without obstructing the field of view and without bringing the user's hand close to the fire source. I was able to put it on the table. For this reason, the risk of a user being burned could be reduced. Moreover, since the size of the fire extinguisher deployed and the size of the periphery of the stovetop were almost the same, the air could be completely shut off. Furthermore, the fire extinguishing tool in the unfolded state has a sheet firmly attached to the main bone, so that the fire could be extinguished smoothly on the stove table. In addition, since the sheet portion of the fire extinguisher is not directly covered with flames, there was no change such as fraying around and dirt due to oil smoke. Therefore, it was possible to reuse (reuse) fire extinguishers once used.

Comparative example

As in the above example, a base material before acid treatment is prepared and used as a fire extinguisher sheet, and the fire extinguishing sheet is folded into a handkerchief and placed in a box (cylinder) in the same manner as in Patent Document 2 described above. A folding fire extinguishing sheet was prepared.
Next, the salad oil was renewed and the pan was covered with a fire extinguishing sheet in the same manner as in the above example. About 20 seconds (taken out of the box: 3 seconds, spread: 6 seconds, covered: 1 second, fire extinguishing: The fire was extinguished in 10 seconds.
It takes time to open the fire extinguishing sheet, and the field of view is blocked during the fire extinguishing, so it takes time to extinguish the fire, and the user needs to bring his hands close to the fire, so be careful not to get burned As a result, it was difficult to cover the fire extinguishing sheet smoothly, and it took time to cover the fire extinguishing sheet. Moreover, after covering the fire extinguishing sheet, the flame could not be extinguished unless the wrinkles were extended to completely block the air. In addition, since fire extinguishing sheets are directly exposed to flames, they can be easily reused (reused) because they are contaminated with oily smoke after use and are difficult to remove. could not.

  INDUSTRIAL APPLICABILITY The present invention has industrial applicability in that it can contribute to the field of use as a fire extinguishing cloth (fire extinguishing sheet) instead of a powdered extinguisher type fire extinguisher.
