Description

[Technical field]

[0001] The present invention relates to a megaphone for use in a fire extinguisher stick. [Background technology]

[0002] Conventionally, there have been known ideas regarding the loading of rescue equipment to be used in the event of a disaster.

[0003] For example, Patent Document 1 describes the loading of rescue equipment such as fire extinguishers and megaphones onto motorcycles and three-wheeled motor vehicles used as a means of transportation during disasters. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3107083 Summary of the Invention [Problem to be solved by the invention]

[0005] The fire extinguisher described in Patent Document 1 is a conventional general fire extinguisher that sprays a powder extinguishing agent by squeezing a lever. The motorcycle or three-wheeled motor vehicle in Patent Document 1 is loaded with various types of rescue equipment, assuming that it will be used by police officers, fire brigade members, Self-Defense Force members, etc. No consideration is given to compactness suitable for hanging on the wall of a private residence or placing on the floor in the corner of a room, for example. In addition, it takes time to find the fire extinguisher and megaphone from among the various types of rescue equipment, which may delay the start of firefighting work or rescue requests.

[0006] Compared to conventional general fire extinguishers, the fire extinguishing stick is a small, lightweight rod-shaped fire extinguishing device that sprays extinguishing agent from the tip, and is suitable for initial fire extinguishing immediately after a fire breaks out (for example, within 2 minutes). On the other hand, for example, if a megaphone can be used immediately when a fire breaks out in a house, residents can go outside and call for rescue, increasing the chances of survival.

[0007] The present invention was created in consideration of these points, and its purpose is to provide a megaphone for a fire extinguisher stick that can be used to request rescue in the event of a fire, etc. [Means for solving the problem]

[0008] The megaphone for a fire extinguisher stick according to the present invention comprises a cylindrical mounting portion (71) that can be attached and detached to the outer wall of the fire extinguisher stick (1), and a cylindrical megaphone body (720) that is axially connected to one end of the mounting portion.

[0009] This megaphone for a fire extinguisher stick has a mouthpiece (75) at the other end of the mounting part, and has a speaker hole (76) on the side of the megaphone body opposite the mounting part (i.e., the side opposite the mounting part).

[0010] For example, when a fire breaks out in a house, a resident who uses a megaphone can pick up a fire stick with a megaphone that is always kept in the room and first remove the megaphone from the outer wall of the fire stick. For example, a resident can hold the fire stick in one hand to put out the fire while holding the megaphone in the other hand to call for rescue.

[0011] When there are two or more residents in a room, a quick response is possible by having one person call for help using the megaphone 70 while another person performs the fire-extinguishing operation using the fire extinguishing stick 1. Taking advantage of the characteristics of the fire extinguishing stick, which is particularly small and lightweight and capable of continuously spraying inert gas, initial fire-extinguishing operations can be performed effectively immediately after a fire breaks out.

[0013] Several embodiments of the megaphone for a fire extinguisher stick according to the present invention will be described with reference to the drawings. The fire extinguisher stick to which this megaphone is attached is a small, lightweight rod-shaped fire extinguisher capable of spraying fire extinguishing agent from the tip. The fire extinguisher stick is kept on hand, for example, in private homes, offices, vehicles, etc., and is used for extinguishing work when a fire breaks out. In this embodiment, a 100-second spray type fire extinguisher stick will be described as a representative example.

[0014] (Fire stick configuration) The configuration of the fire extinguisher stick 1 will be described with reference to Figs. 1 to 3. The fire extinguisher stick 1 is composed of a stick body 3, a protective cap 4, a handle 5, and an end cap 6, which are coaxially arranged along a central axis O. A megaphone (illustrated as a slim type megaphone of the first embodiment) 70S is detachably attached to the outer wall of the fire extinguisher stick 1. The handle 5 is integrally connected to the stick body 3. The protective cap 4 is detachable from the stick body 3. The end cap 6 is detachably attached to the handle 5 on the side opposite to the stick body 3. The stick body 3 is made of metal, and the protective cap 4, the handle 5, and the end cap 6 are made of resin.

[0015] Hereinafter, regarding the megaphone, matters common to the slim type megaphone 70S of the first embodiment and the standard type megaphone 70L of the second embodiment will be described as "megaphone 70". Fig. 1 shows a state in which the megaphone 70 is attached to the outer wall of the fire extinguishing stick 1. Fig. 2 shows a state in which the megaphone 70 has been removed from the state of Fig. 1. Fig. 3 shows a state in which the protective cap 4 and the end cap 6 have been removed from the state of Fig. 2. The side from which the extinguishing agent is sprayed, which is the left side of the paper in Figs. 1 to 3, is defined as the tip side. The side opposite the tip side of the fire extinguishing stick 1 is referred to as the base side.

[0016] The stick body 3 is composed of a cylindrical metal tube, and a cartridge filled with a fire extinguishing agent is stored inside. An ignition agent 7, equivalent to the head powder of a match, is applied or stuck to the tip of the stick body 3. The handle 5 is connected to the stick body 3 at its tip end, and has a hollow cylindrical portion 15 that opens to the base end. The user can hold the handle 5 when using the fire extinguisher stick 1.

[0017] The protective cap 4 is a cylinder with a closed end and a bottom, and is placed on the stick body 3 from the tip side to protect the ignition agent 7. A protective cap gripping part 13 with an axial protrusion is provided on the outer wall on the base end side of the protective cap 4. The user can hold the protective cap gripping part 13 and remove the protective cap 4 towards the tip side.

[0018] The end cap 6 is detachably attached to the hollow cylindrical portion 15 of the handle 5 from the base end side of the fire extinguisher stick 1. A side agent 10 is applied or stuck to the tip of the end cap 6. An end cap grip portion 12 having an axial ridge formed thereon is provided on the outer wall of the end cap 6. A user can hold the end cap grip portion 12 and fit the end cap 6 into the hollow cylindrical portion 15. The outer wall of the end cap 6 fits into the inner wall of the hollow cylindrical portion 15 with a light interference fit to prevent it from falling off.

[0019] With the end cap 6 attached to the hollow cylindrical portion 15, the side agent 10 is contained inside the handle 5. When removing the end cap 6, the user can remove the end cap 6 from the hollow cylindrical portion 15 of the handle 5 by holding the end cap gripping portion 12 and pulling it out.

[0020] As shown in FIG. 1, the megaphone 70 includes a cylindrical attachment portion 71 and a megaphone body 720. In this embodiment, the attachment portion 71 is detachable from the outer wall of the protective cap 4, and is positioned in the axial direction by abutting against the tip side of the protective cap grip portion 13. The megaphone body 720 is axially connected to one end of the attachment portion 71. The megaphone 70 has a mouthpiece 75 at the other end of the attachment portion 71, and has a loudspeaker 76 on the opposite side of the attachment portion 71 of the megaphone body 720. The detailed configuration of the megaphone 70 will be described later. When using the fire extinguisher stick 1, the megaphone 70 is first removed from the outer wall of the protective cap 4.

[0021] (How to use the fire extinguisher stick) With reference to FIG. 4, the method of using the fire extinguisher stick will be described. After the megaphone 70 is first removed, in the first stage, the user removes the protective cap 4 from the stick body 3 of the fire extinguisher stick 1. In the second stage, the user removes the end cap 6 from the handle 5. This exposes the ignition agent 7 and the side agent 10 that were covered during storage. In the third stage, the user rubs the side agent 10 of the end cap 6 against the ignition agent 7 of the stick body 3 to ignite it, and the extinguishing agent sealed inside the stick body 3 is sprayed. In the fourth stage, the user points the nozzle at the bottom of the flame to put out the fire.

[0022] In the third stage, when the ignition agent 7 in the stick body 3 is ignited, the components inside the cartridge undergo a chemical reaction, and the extinguishing agent is sprayed from the tip of the stick body 3. In more detail, potassium nitrate and dicyandiamide combust through a chemical reaction, and an inert gas containing white vapor-like potassium particles is sprayed. The large amount of potassium radicals have a suffocating and suppressing effect that depletes the oxygen inside and around the flame, interrupting the chain of combustion.

[0023] (Comparison between the fire extinguisher stick and a comparable type of fire extinguisher) A conventional general powder fire extinguisher (general fire extinguisher) is used as a comparative form, and the characteristics of the fire extinguisher stick are compared with the comparative form. For example, the size of the 100-second spray type fire extinguisher stick, excluding accessories, is 4 cm in diameter, 33 cm in total length, and weighs 365 g, making it small and lightweight.

[0024] The general fire extinguisher of the comparative embodiment uses a large diameter cylindrical metal container and is heavy, weighing, for example, 5 kg. It is difficult to spray extinguishing agent at a flame source in a high place or a narrow space using a heavy fire extinguisher. In addition, it is necessary to hold the fire extinguisher body with one hand and hold the lever with the other hand to spray, which means both hands are occupied and operability is poor. In contrast to the comparative embodiment, the fire extinguisher stick used in this embodiment is small and lightweight and can be used with one hand, making it easy to operate and convenient. Below, we will compare each item.

[0025] (1) Spray time: The fire extinguishing stick can be sprayed continuously for up to 100 seconds. This is effective in extinguishing a fire in its initial stage, which is said to be extinguished within two minutes of the fire starting. (2) Weight: The fire extinguisher stick (excluding accessories) is lightweight at 365g, making it easy to carry in the event of a fire. (3) Residues: Fire extinguishing sticks spray inert gas, so no harmful residues remain. This makes it easy to restore items and equipment in the affected area after the fire is extinguished. (4) Fire extinguisher sticks can be used to deal with flammable gas fires that general fire extinguishers cannot handle.

[0026] (5) Expiration date: The expiration date of the fire extinguisher stick is 15 years, which is longer than that of ordinary fire extinguishers. (6) Durability: The fire extinguisher stick is non-pressurized, making it highly durable and impact resistant. (7) Regular inspection: Fire extinguisher sticks do not require regular inspection by a legally qualified person. (8) Safety and environment: The gas used to propel the fire extinguisher is an inert gas. This means that it does not adversely affect the breathing or eyesight of the operator or those around, and it does not contribute to global warming or the destruction of the ozone layer.

[0027] For comparison, the specifications for a general-purpose fire extinguisher are as follows: (1) Injection time: The injection period of a general fire extinguisher is, for example, about 15 seconds. In many cases, it is not possible to achieve initial extinguishing of the fire. (2) Weight: A typical fire extinguisher weighs about 5 kg, making it difficult to carry in the event of a fire. (3) Residues: General fire extinguishers leave chemical residue and dirt behind after spraying, making it difficult to restore items and equipment in affected areas after the fire is extinguished. (4) Ordinary fire extinguishers are not suitable for flammable gas fires.

[0028] (5) Expiration date: Ordinary fire extinguishers deteriorate quickly and have a short expiration date. (6) Durability: Since general fire extinguishers are pressurized, they have poor durability and impact resistance. (7) Regular inspection: General fire extinguishers require regular inspection by a legally qualified person, and are complicated to handle. (8) Safety and the environment: The chemicals sprayed by ordinary fire extinguishers can easily affect the breathing and eyesight of the operator and those nearby, and are also a cause of global warming and the destruction of the ozone layer.

[0029] Next, the configuration of the megaphone for the fire extinguisher stick will be described. In the multiple embodiments, the substantially same configuration will be given the same reference numerals and the duplicated description will be omitted. The first to third embodiments will be collectively referred to as "the present embodiment". Items common to the slim type megaphone 70S of the first embodiment and the standard type megaphone 70L of the second embodiment will be described as "megaphone 70".

[0030] Regarding the storage form when attached to the fire extinguisher stick 1, the slim type megaphone 70S of the first embodiment is intended for wall hanging. The standard type megaphone 70L of the second embodiment is intended for floor placement and is slightly larger than the slim type megaphone 70S. Note that the initial letter S of "standard" overlaps with the S of the slim type, so it is substituted with L for "large."

[0031] First Embodiment The slim type megaphone 70S of the first embodiment will be described with reference to Fig. 5 to Fig. 9. Fig. 5 to Fig. 8(b) show the external shape of the slim type megaphone 70S alone detached from the fire extinguishing stick 1, as viewed from each direction. Fig. 9 and Fig. 8(c) show the state in which the fire extinguishing stick 1 to which the slim type megaphone 70S is attached is hung on a wall W by a bracket B. Note that the illustrated direction in Fig. 8(c) is different from the direction of the cross-section indication line in Fig. 9, but for convenience, it is aligned with the direction in Fig. 8(a) and (b).

[0032] Megaphone 70 is formed of a flexible resin material, and includes a cylindrical attachment portion 71 centered on central axis O, and a megaphone body 720. Attachment portion 71 is detachably attached to the outer wall of fire extinguisher stick 1. In this embodiment, attachment portion 71 is detachably attached to the outer wall of protective cap 4, not to the outer wall of handle 5 of fire extinguisher stick 1. Since handle 5 is not covered by megaphone 70, a user can grip handle 5 without being hindered. Megaphone body 720 is axially connected to one end of attachment portion 71.

[0033] The megaphone 70 has a mouthpiece 75 at the other end of the mounting part 71, that is, the end opposite to the megaphone body 720. The mouthpiece 75 also serves as a fitting hole when the mounting part 71 is attached to and detached from the outer wall of the fire extinguisher stick 1. The megaphone 70 also has a loudspeaker 76 at an open end 74, which is the end of the megaphone body 720 opposite the mounting part. The megaphone 70 loudens the sound input by the user to the mouthpiece 75 and outputs it from the loudspeaker 76. Preferably, the open end 74 has a rounded edge 743 on the outer periphery (i.e., the corners are rounded). This makes it possible to reduce the impact when the user accidentally hits the megaphone 70 against a person or object.

[0034] The mounting part 71 is formed so as to be elastically deformable in the radial direction. Figs. 5 to 8 show the radial shape of the mounting part 71, which is reduced in diameter when the megaphone is in a single unit and deformed into an elliptical shape. When the mounting part 71 is attached to the outer wall of the fire extinguishing stick 1, the inner wall 715 of the mounting part 71 elastically expands and contacts the outer wall of the fire extinguishing stick 1. The inner wall 715 of the mounting part 71 has a length of about several centimeters in the axial direction and is in surface contact with the outer wall of the fire extinguishing stick 1, so that the mounting position of the megaphone 70 is stable. In addition, the mounting part 71 is provided with a ring part 719 through which a neck cord 79 that the user wears around the neck passes.

[0035] The megaphone body 720 is formed with a flat cross-sectional shape perpendicular to the central axis O. In the slim type megaphone 70S, as shown in Figs. 8(a) and (b), the megaphone body 720 is formed in a D-shape with a part of the circumference connected by a string in at least a part of the cross-section perpendicular to the central axis O. That is, the megaphone body 720 of the slim type megaphone 70S has an arcuate curved surface portion 72 and one interference avoidance portion 73. The arcuate curved surface portion 72 is formed along a part of an imaginary circle indicated by a two-dot chain line in the cross-section perpendicular to the central axis O. The interference avoidance portion 73 is formed inside the imaginary circle, and both ends are connected to the arcuate curved surface portion 72.

[0036] In slim type megaphone 70S, arcuate curved surface portion 72 tapers in diameter from mounting portion 71 toward the non-mounting portion side, and then extends to open end 74 with a substantially constant diameter. Interference avoidance portion 73 is formed in a substantially planar shape. As a result, the distance from central axis O to the outer wall of interference avoidance portion 73 is shorter than that of arcuate curved surface portion 72, so that interference with an object is avoided when interference avoidance portion 73 is placed close to the object. Interference avoidance portion 73 is not limited to a substantially planar shape, and may be formed of a gently curved surface with a smaller curvature than arcuate curved surface portion 72, or multiple bent surfaces.

[0037] Specifically, the wall W when the stick is hung on the wall becomes the object with which the interference avoidance part 73 avoids interference. As shown in Fig. 9 and Fig. 8(c), the fire extinguisher stick 1 to which the slim type megaphone 70S is attached is hung on the wall W by the bracket B. The bracket B has a pair of cylindrical locking parts B1 joined to a base B3 via a leaf spring B2. The leaf spring B2 biases the pair of locking parts B1 inward. In the free state shown by the broken line in Fig. 8(c), the distance between the pair of locking parts B1 is narrower than the diameter of the mounting part 71. When the user presses the mounting part 71, the leaf spring B2 spreads outward, and the mounting part 71 is clamped between the pair of locking parts B1.

[0038] At this time, the orientation of slim type megaphone 70S with respect to central axis O is set so that interference avoidance section 73 faces wall W, thereby preventing megaphone body 720 from interfering with wall W. Therefore, when hanging and storing on wall W of a private residence, office, etc., the protruding dimension from wall W can be reduced, enabling compact storage.

[0039] Next, referring to Fig. 10, a situation in which the fire extinguisher with megaphone of this embodiment is used will be described. In an apartment or condominium, the fire extinguisher with megaphone is preferably kept in each room, not in a common hallway. For example, when a fire breaks out in a house, a resident in a room on the second floor or higher picks up the fire extinguisher with megaphone hanging on the wall or placed on the floor, and first removes the megaphone 70 from the outer wall of the fire extinguisher with megaphone 1.

[0040] A resident using megaphone 70 shouts "Fire! Help!", for example, from a second-floor window to the outside. Because fire extinguisher stick 1 is small and lightweight, it is possible to hold fire extinguisher stick 1 in one hand to put out a fire, while holding megaphone 70 in the other hand to call for rescue. In addition, by hanging neck cord 79 through ring portion 719 around the user's neck, the user can use both hands freely.

[0041] When there are two or more residents in a room, a rapid response is possible by having one person call for rescue using the megaphone 70 while another person performs fire-extinguishing work using the fire extinguishing stick 1. Taking advantage of the characteristics of the fire extinguishing stick 1, which is particularly small and lightweight and can continuously spray inert gas for 100 seconds, initial fire-extinguishing work can be performed effectively immediately after a fire breaks out (for example, within two minutes).

[0042] In addition to fires, the Megaphone 70 can also be used to call for rescue in situations other than fire: when the surrounding area is flooded due to torrential rain or river overflowing, when a house collapses in an earthquake and you are left stranded in a room, or when a robber or suspicious person breaks into your home.

[0043] <Second embodiment> The standard type megaphone 70L of the second embodiment will be described with reference to Fig. 11 to Fig. 13, mainly focusing on the differences from the slim type megaphone 70S. Fig. 11 to Fig. 13 show the external shape of the standard type megaphone 70L alone detached from the fire extinguishing stick 1, as viewed from each direction.

[0044] Megaphone body 720 is formed with a flat cross-sectional shape perpendicular to central axis O. In standard type megaphone 70L, as shown in Figures 13(a) and (b), in at least a part of the cross-section perpendicular to central axis O, megaphone body 720 has parts of the circumference connected by strings on both sides of a straight line passing through central axis O. In other words, megaphone body 720 of standard type megaphone 70L has two arcuate curved surface portions 72 and two interference avoidance portions 73.

[0045] In a cross section perpendicular to the central axis O, the arc curved surface portion 72 is formed along an imaginary circle indicated by a two-dot chain line, and expands in diameter in a tapered manner with a substantially constant gradient from the mounting portion 71 toward the open end 74. In approximately half of the range on the mounting portion 71 side in the axial direction of the megaphone body 720, the arc curved surface portion 72 is formed along the entire circumference of the imaginary circle. In approximately half of the range on the open end 74 side, the arc curved surface portion 72 is formed along a part of the imaginary circle. Two interference avoidance portions 73, for example, substantially planar, formed inside the imaginary circle have both ends connected to the arc curved surface portion 72.

[0046] As shown by the dashed line in Fig. 12, the standard type megaphone 70L attached to the fire extinguisher stick 1 is placed on the floor so that the open end 74 is in contact with the floor F. In this case, by placing the two interference avoidance parts 73 in a direction parallel to the wall W, it is possible to bring it as close as possible to the wall W, thereby reducing the space it occupies in a room, hallway, etc.

[0047] <Third embodiment> A third embodiment will be described with reference to Figs. 14 to 16. In the third embodiment, in the fire extinguisher stick 1 in a stored state, safety glasses 80 are housed between the inner wall of the megaphone 70 and the outer wall of the protective cap 4. As shown in Fig. 14, the safety glasses 80 are formed of a flexible sheet 81 that is approximately 20 cm wide x 8 cm long. Hereinafter, according to the orientation of the safety glasses 80 illustrated in Fig. 14, i.e., the orientation when worn by a user on the face, the longitudinal direction of the safety glasses 80 will be referred to as the "lateral direction" and the transverse direction will be referred to as the "vertical direction".

[0048] Flexible sheet 81 has an outer shape with the four corners and the part that goes over the nose cut out in a round shape, and has sight windows 82 at positions corresponding to both eyes. Heat-resistant eyepiece film 83 is attached so as to cover sight window 82. Ear straps 84 are attached to both lateral ends of flexible sheet 81, so that the user can wear safety glasses 80 by hanging ear straps 84 around the ears. In addition, a simple lighting unit 85 is provided above and between both eyes.

[0049] 15 and 16(b) show the storage state of the fire extinguisher stick 1 to which the standard type megaphone 70L is attached. The annular space 78 between the standard type megaphone 70L and the protective cap 4 is sufficiently wide. Therefore, the safety glasses 80 can be stored in almost the original shape on one side of the protective cap 4 near the open end 74, and the safety glasses 80 can be stored by slightly curving them from the open end 74 to the back. In addition, for example, a disaster prevention mask 87 can be stored on the other side of the protective cap 4. Not limited to the disaster prevention mask 87, items such as a handkerchief, a disaster prevention hood, and work gloves may be stored in the annular space 78.

[0050] 16(a) shows the slim type megaphone 70S attached to the fire extinguisher stick 1. In the slim type megaphone 70S, the annular space 78 between the protective cap 4 is relatively narrow, but the safety glasses 80 can be accommodated in the annular space 78 by curving the vertical edge of the flexible sheet 81 to fit the annular space 78.

[0051] By wearing the safety glasses 80 when evacuating from a fire or during firefighting work, the user can protect his / her eyes from flames and smoke. In addition, since general safety glasses, which are stored by folding the frame, are rigid and have a small degree of freedom of deformation, it is difficult to store not only the slim type megaphone 70S but also the standard type megaphone 70L in the annular space 78. In contrast, the safety glasses 80 used in the third embodiment have a flexible sheet 81 as a base material, so they can be curved and inserted into the annular space 78 and stored together with the fire extinguisher stick 1.

[0052] <Other embodiments> (a) The fire extinguisher stick is not limited to the configuration of the above embodiment, and may be any rod-shaped fire extinguisher that can spray extinguishing agent from the tip and has an outer wall to which the attachment part 71 of the megaphone 70 can be detached. If the user can easily hold it, the attachment part 71 may be attached to the outer wall of the handle 5.

[0053] (b) The specific shape of megaphone body 720 is not limited to the shapes exemplified in Figures 5 to 8 and 11 to 13, and may be at least cylindrical. The cross-sectional shape perpendicular to the axis may not be flat, and may be circular, etc. The ratio and gradient of the axial length of each part may be set appropriately taking into consideration the sound amplification function, moldability, design, etc.

[0054] (c) The open end 74 of the mounting portion of the megaphone body 720 is not limited to a configuration in which the edge 743 on the outer periphery is rounded, and for example, a ring-shaped cushioning member may be attached to the outer periphery to absorb impact.

[0055] As described above, the present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit of the present invention. [Explanation of symbols]
