[0009] [Embodiment] The following embodiments relate to the acoustic rods 10 and 10A shown in Figures 1 to 7, and include not only essential configurations but also optional and preferred configurations. The embodiments of the acoustic rods 10 and 10A will be described below with reference to the accompanying drawings.

[0010] [First embodiment] The sound bar 10 according to the first embodiment shown in FIGS. 1 to 3 includes a main body portion 20, a cap portion 30, an explosive cartridge 40, a safety cover 50, and an attachment member 60.

[0011] The main body 20 is formed into a rod shape extending in the axial direction by, for example, cutting an aluminum alloy. As shown in Fig. 3, a cylindrical core rod 22 and a cylindrical member 23 covering an outer peripheral surface 22R of the core rod 22 are provided at both axial end portions 21 of the main body 20. Furthermore, a space 20S is formed in the radial direction between the core rod 22 and the cylindrical member 23.

[0012] A plurality of (for example, four) first through holes 23H that penetrate the cylindrical member in the radial direction are formed in the cylindrical member 23. The first through holes 23H communicate the space portion 20S with an internal space 30S, which will be described later.

[0013] The inner circumferential surface 23R1 of the cylindrical member 23 is formed with a sliding portion 23a formed of recesses and protrusions.

[0014] A groove 24 is formed in the circumferential direction (see FIG. 2) on the outer peripheral surface 23R2 of the cylindrical member 23. A gasket 25 formed in an annular shape from synthetic rubber is disposed in the groove 24. The inner peripheral surface of the gasket 25 in the radial direction contacts the outer peripheral surface of the cylindrical member 23. Meanwhile, the outer peripheral surface of the gasket 25 in the radial direction contacts the inner peripheral surface of the cap portion 30.

[0015] The cap portions 30 are disposed at both end portions 21 of the main body portion 20, and are provided so as to be able to abut against the main body portion 20 in the axial direction. That is, two cap portions 30 are provided on the main body portion 20, for example, cap portion 30A is provided on one end in the axial direction and cap portion 30B is provided on the other end in the axial direction. The cap portions 30A and 30B have the same configuration. The cap portions 30 are formed into a cylindrical shape by, for example, cutting an aluminum alloy. Furthermore, the cylindrical cap portion 30 forms an internal space 30S in cooperation with the main body portion 20.

[0016] Each of the cap portions 30 has a plurality of (for example, four) second through holes 30H formed therein, which penetrate the cap portion 30 in the radial direction.

[0017] The gunpowder cartridge 40 includes gunpowder 41 that is solidified into a cylindrical shape and contains air, and a covering member 42 that covers the gunpowder 41. The gunpowder 41 is, for example, black powder 41. The covering member 42 is formed by applying the gunpowder 41 to, for example, a piece of paper.

[0018] As described above, the axial end of the cylindrically formed core rod 22 constitutes the first engagement portion 71, and the covering member 42 of the explosive cartridge 40 is formed with the cylindrical second engagement portion 72 with which the first engagement portion 71 can engage. Therefore, the explosive cartridge 40 can be attached to the end of the core rod 22 by the first engagement portion 71 and the second engagement portion 72. In addition, the tip portion of the covering member 42 is inserted into the space 20S.

[0019] 2, the safety cover 50 includes a cover body 51, a pair of covering portions 52, and a plurality of holding portions 53. The safety cover 50 is integrally formed from a rigid metal material such as stainless steel.

[0020] The cover body 51 is formed in a generally rectangular flat plate shape, and is formed so as to be slightly longer in the axial direction than the lengths of the main body portion 20 and the cap portion 30. A plurality of slits 51S are formed in the cover body 51. Two slits 51S form one set, and the two slits 51S that make up one set are arranged side by side in a direction intersecting at right angles to the axial direction.

[0021] The pair of covering portions 52 are arranged at both axial ends of the cover body 51, bent from the cover body 51, and disposed so as to face each other. The pair of covering portions 52 are disposed so as to cover the entire area of ​​the cap portion 30 with a small gap provided between them in the axial direction (see FIG. 1). Therefore, when a user moves around with the sound bar 10 attached to an article 70 such as a backpack (see FIG. 4), the covering portions 52 prevent foreign objects from coming into contact with the cap portion 30, thereby preventing the sound bar 10 from operating improperly.

[0022] The plurality of holding portions 53 are configured in pairs, and the two holding portions 53 configuring one pair are arranged at both ends of the cover body 51 in the intersecting direction, bent from the cover body 51, and provided so as to face each other. The cap portion 30 is held between the pair of holding portions 53.

[0023] The mounting member 60 comprises, in the thickness direction, a base member 61, a hook 62 of a mechanical fastener provided on the surface of the base member 61, and a loop 63 of a mechanical fastener provided on the back surface of the base member 61. The hook 62 and the loop 63 are engageable with each other.

[0024] The mounting member 60 includes a head portion 64 that is wide in the axial direction and leg portions 65 that are narrower than the head portion 64. In addition, in a direction perpendicular to the axial direction, the length of the leg portions 65 is longer than the length of the head portion 64. In addition, the head portion 64 is formed with a hole portion 66 through which the leg portions 65 can be inserted.

[0025] For example, for one of the multiple mounting members 60, the tip portion of the leg 65 is passed through the slit in the safety cover 50, the main body portion 20 is then positioned axially between a pair of covering members 42, and the main body portion 20 can be attached to the safety cover 50 using the mounting member 60 by engaging the hook 62 with the loop 63.

[0026] At least one of the remaining attachment members 60 is subjected to the same operation to attach the sound bar 10 to an article 70 such as a backpack (see FIG. 4).

[0027] Next, the operation of using the sound stick 10 to intimidate wild animals such as bears, boars, monkeys, etc. will be described with reference to FIGS.

[0028] When the user HU shown in Figure 4 finds a wild animal such as a bear, boar, or monkey, he or she first takes off the backpack or other item 70 from his or her shoulder, and then removes the acoustic stick 10 from the backpack or other item 70 by disengaging the hook 62 and the loop 63 on the attachment member 60.

[0029] Next, in the sound bar 10, the hook 62 and the loop 63 of the mounting member 60 are disengaged from each other, thereby removing the main body portion 20 and the cap portion 30 from the safety cover 50.

[0030] Next, the user firmly grasps the main body portion 20 with five fingers as shown in FIG.

[0031] Thereafter, while still holding the main body portion 20, the user abuts, for example, the lower cap portion 30B against a hard object such as hard ground or wood. This abutting action brings the cap portion 30B closer to the main body portion 20 in the axial direction.

[0032] 3, the air contained in the gunpowder 41 is compressed, and as the cap portion 30B and the gunpowder cartridge 40 move relative to the main body portion 20, the covering member 42 of the gunpowder cartridge 40 slides against the convex portion of the sliding portion 23a, causing the gunpowder 41 applied to the covering member 42 to burn and ignite, thereby exploding the gunpowder 41. The explosion of the gunpowder 41 then produces a popping sound (a loud gunshot sound of about 110 decibels).

[0033] If the wild animal does not stop approaching after one activation of the sound wand 10, another popping sound is generated by operating the other cap portion 30A in the same manner.

[0034] The sound bar 10 according to this embodiment includes a rod-shaped main body 20, a cap 30 that can be brought into contact with the main body 20 and forms an internal space 30S in cooperation with the main body 20, and an explosive cartridge 40 that is placed in the internal space 30S and contains explosives 41. Therefore, by bringing the cap 30 into contact with the sound bar, the explosives 41 are exploded, generating a popping sound, thereby preventing wild animals from approaching.

[0035] Since the sound bar 10 is formed in a rod shape, it is easy to hold and carry, making it ideal for outdoor activities.

[0036] Furthermore, since the sound wand 10 according to this embodiment has the shape described above, the operation to generate the gunshot sound can be intuitively understood, and it can be used quickly even in an emergency.

[0037] The sonic wand 10 according to this embodiment only produces the sound of a gunshot to scare wild animals using the gunpowder 41, and does not require the gunpowder 41 to fire a bullet, making it possible to minimize the amount of gunpowder 41 used and reducing the burden on the environment. Furthermore, the sonic wand 10 according to this embodiment only produces the sound of a gunshot to scare wild animals using the gunpowder 41, and does not fire a bullet using the gunpowder 41, so it does not harm wild animals and can provide a humane defense tool.

[0038] Furthermore, in the sound bar 10 according to this embodiment, the main body 20 is provided with a cap portion 30A on one axial end and a cap portion 30B on the other axial end, so that the sound bar 10 can generate two loud popping sounds, significantly reducing the risk of being attacked by wild animals.

[0039] Such a sound wand 10 is suitable for outdoor enthusiasts who enjoy activities such as camping, hiking, and fishing. The sound wand 10 is also suitable for forestry workers, surveyors, and wildlife researchers. Furthermore, the sound wand 10 is suitable for residents living in areas where wild animals such as bears are found near their homes.

[0040] [Second embodiment] Next, an acoustic rod 10A according to a second embodiment will be described with reference to Figures 6 and 7. The main body 20A of the acoustic rod 10A according to the second embodiment is formed so that it can be separated into two parts, and includes a storage space 20S1 that is exposed when the main body 20A is separated. A spare explosive cartridge 40A and a spare packing 25A are stored in the storage space 20S1.

[0041] A screw 28 is formed at the end of one portion of the main body portion 20A, and a screw groove 29 that can be threadably engaged with the screw is formed at the end of the other portion of the main body portion 20A.

[0042] According to the acoustic rod 10A of this embodiment, even after the acoustic rod 10A has been activated twice, a popping sound can be generated again by dividing the main body portion 20A, removing the spare gunpowder cartridge 40A, and attaching the spare gunpowder cartridge 40A to the end of the core rod 22 of the main body portion 20A.

[0043] The disclosure of the present invention described above can be summarized at least as follows.

[0044] The acoustic rod 10 comprises a rod-shaped main body portion 20, a cap portion 30 that can be brought into contact with the main body portion 20 and forms an internal space 30S in cooperation with the main body portion 20, and an explosive cartridge 40 that is arranged in the internal space 30S and contains explosives 41.
