Description

[Technical Field]

[0001] The present invention relates to the technical field of animal repellent sound generators that generate repellent sounds to scare away wild animals such as bears and boars. [Background technology]

[0002] Recently, there have been many incidents of wild animals such as bears and boars appearing in human living areas and causing harm to people. Therefore, it has been suggested that people carry wild animal repellent items with them in case of possible encounters with wild animals. One such portable wild animal repellent item that has been known in the past is one that uses rocket fireworks (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3124481 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the use of rocket fireworks as in Patent Document 1 has the problem that it is difficult to predict the flight distance and flight direction of the rocket fireworks, and the places where they can be used are limited from the viewpoint of ensuring safety. Therefore, it has been proposed to repel wild animals by using the explosive sound of firecrackers or explosive crackers, rather than by launching them like rocket fireworks. However, in this case, there is a demand for increasing the volume of the explosive sound to improve the repelling effect, and this is the problem that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in consideration of the above-mentioned circumstances and with the aim of solving the above-mentioned problems. The invention of claim 1 is an animal repellent sound generator comprising a metal cylindrical main body portion with an opening at the tip end and a grip portion provided at the base end of the main body portion, which generates a repellent sound for repelling animals by causing a firecracker inserted through the opening at the tip end of the main body portion to explode inside the main body portion, and is characterized in that the main body portion has a cone shape with a wider diameter at the tip end than at the base end. The invention of claim 2 is the animal repellent sound generator according to claim 1, characterized in that the shape of the opening at the tip of the cylindrical main body is circular, or elliptical or oblong with the major axis facing horizontally. The invention of claim 3 is the animal repellent sound generator according to claim 1, characterized in that the animal repellent sound generator further comprises a fall prevention part that prevents firecrackers inserted into the main tube part from falling out. [Effects of the Invention]

[0006] The animal repellent sound generator of the present invention generates a repellent sound that is loud, reverberant, and highly directional, thereby effectively repelling wild animals. [Brief explanation of the drawings]

[Figure 5] FIG. 10 is a partial cross-sectional front view of an animal repellent sound generator according to a fifth embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0008] The following describes an embodiment of the present invention with reference to the drawings. In the drawings, reference numeral 1 denotes an animal repellent sound generator that generates a repellent sound to repel wild animals such as bears. The animal repellent sound generator 1 is configured with a cylindrical main body 2, a grip 3, etc., which will be described later.

[0009] The cylindrical main body 2 is a cylindrical member made of metal (e.g., stainless steel, brass, cast iron, etc.) with an opening 2a at the tip end, and in this embodiment, the tip end opening 2a is circular and the tip end has a conical shape with a larger diameter than the base end.

[0010] A pipe-shaped grip portion 3 that is gripped by a user is integrally provided on the base end side of the cylindrical main body portion 2 in a continuous state from the cylindrical main body portion 2.

[0011] Next, a method of using the animal repellent sound generator 1 will be described. A user first inserts a firecracker 4 into the tube body 2. Then, the user bends the fuse 4a of the firecracker 4 and hooks the bent fuse 4a around the periphery of the distal opening 2a of the tube body 2, exposing the distal end of the fuse 4a to the outside through the distal opening 2a of the tube body 2. In this state, the user holds the handle 3 and, with the distal opening 2a of the tube body 2 facing forward, ignites the fuse 4a of the firecracker 4 using an ignition tool (not shown) such as a lighter. The ignited fuse 4a of the firecracker 4 explodes within the tube body 2, generating a loud repulsive sound. Because the tube body 2 has a cone shape with a larger diameter at the distal end than at the proximal end, the volume and reverberation of the repulsive sound are increased, and the repulsive sound is generated with excellent directionality toward the forward direction of the distal opening 2a of the tube body 2.

[0012] Here, the animal repellent sound generator 1 is set to a size that is easy to carry and handle. Specific examples include an overall length of 180 to 270 mm for the animal repellent sound generator 1, a length of 120 to 180 mm for the tubular main body 2, a diameter of 50 to 70 mm for the distal end opening 2a, and a diameter of 15 to 25 mm for the proximal end, and a length of 40 to 60 mm and a diameter of 15 to 25 mm for the grip portion 3, but the animal repellent sound generator 1 is not limited to these specific examples.

[0013] In the embodiment of the present invention configured as described above, the animal repellent sound generator 1 comprises a metal cylindrical tube body 2 having an opening 2a at its distal end and a grip 3 provided at the proximal end of the tube body 2. A firecracker 4 inserted through the distal opening 2a of the tube body 2 is exploded inside the tube body 2 to generate a repelling sound for repelling animals. In this device, the tube body 2 has a cone shape (in this embodiment, a circular cone shape) that is wider at its distal end than at its proximal end. Because the tube body 2 has a cone shape that is wider at its distal end than at its proximal end, the volume and reverberation of the repelling sound generated within the tube body 2 are enhanced, and the repelling sound is generated with excellent directionality toward the front, in the direction in which the distal opening 2a of the tube body 2 faces, thereby effectively repelling animals.

[0014] Of course, the present invention is not limited to the above-described embodiment (first embodiment) and includes various modifications and configurations other than those described above. For example, the shape of the tip-side opening 2a of the tube-pair main body 2 may be elliptical or oval, as shown in the second and third embodiments of FIGS. 3(A) and 3(B). When the tip-side opening 2a is elliptical or oval, the tube main body 2 has an elliptical or oval cone shape. However, by using the device with the major axis of the ellipse or oval oriented horizontally, the directionality of the repelling sound can be narrowed vertically and widened horizontally. In this case, the shape of the grip 3 can be made elliptical or oval to match the shape of the tube main body 2, allowing the user to easily identify the direction of the major axis of the tube main body 2.

[0015] 4 and 5, a fall-off prevention portion 2b can be provided to prevent the firecracker 4 inserted into the tube main body 2 from falling out. In these fourth and fifth embodiments, the fall-off prevention portion 2b is provided on the tip side of the tube main body 2 so as to cover at least a part of the lower part of the tip-side opening 2a of the tube main body 2. In this case, in the fourth embodiment shown in Fig. 4, the fall-off prevention portion 2b is formed by extending and bending a part of the periphery of the tip-side opening 2a of the tube main body 2, and in the fifth embodiment shown in Fig. 5, the fall-off prevention portion 2b is formed by fixing a part for preventing the fall-off to the inner circumferential surface of the tube main body 2 using fixing means (not shown, but welding, rivets, etc.). By providing the fall prevention part 2b in this manner so as to cover at least a portion of the lower part of the tip side opening 2a of the tube main body part 2, it is possible to prevent the firecrackers 4 inserted into the tube main body part 2 from accidentally falling out, and the sound of the firecrackers 4 exploding inside the tube main body part 2 is reflected by the fall prevention part 2b, thereby increasing the reverberation and producing a stronger repelling sound. Furthermore, the anti-fall part for preventing the firecrackers 4 from falling off is not limited to that of the fourth and fifth embodiments. For example, a locking fitting for hooking a string for bundling the firecrackers can be provided in the middle of the tube main body in the tube length direction, and the locking fitting can be used as the anti-fall part for the firecrackers.
