Description

  The present invention relates to a bear avoidance bell, and more particularly to a bear avoidance bell that can be easily switched between a warning sound generation state that generates a warning sound and a warning sound stop state that does not generate a warning sound.

Conventionally, bear avoiding bells used for hiking and taking wild vegetables are known, and such bear avoiding bells oscillate inside the acoustic one part and collide with the acoustic one part. And a striking part for generating a warning sound.
These conventional bear avoidance bells are annoying to others when a warning sound is generated in, for example, a train or an urban area, so switch between a warning sound generation state that generates a warning sound and a warning sound stop state that does not generate a warning sound. A possible bear avoidance bell has been proposed (for example, Patent Document 1).
The bear avoidance bell of Patent Document 1 has a configuration in which a female screw portion of the acoustic one portion is screwed with a male screw portion of the striking portion side. A warning sound is generated by allowing movement. On the other hand, when the warning sound is stopped, the external thread of the striking part is disengaged upward from the female thread part of the acoustic one part to hold the striking part on the inner surface of the acoustic one part, thereby generating a warning sound. It is supposed not to let you.

Hereinafter, the present invention will be described with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a bear avoidance bell. When the user holds the bear avoidance bell 1 when hiking or taking a wild vegetable, a warning sound is generated during walking. To inform the bear of the existence of a human being.
The bear avoidance bell 1 of the present embodiment has a spherical bell means 2 that generates a warning sound “tilling,” when swung, and a substantially cylindrical shape in which the lower face is opened and the bell means 2 is accommodated therein. Casing 3 and a switching member 4 slidably provided on the inner peripheral surface of the lower side of the casing 3.

The bell means 2 has the same configuration as a conventionally known metal bell. That is, the bell means 2 includes a bell main body 2A having a hollow spherical shape and a rolling piece 2B as a striking member accommodated in the bell main body 2A. The bell main body 2A is made of a non-magnetic metal (for example, copper), and a linear slit is formed at a lower end portion. The rolling piece 2B is made of iron, which is a magnetic material, and has a cubic shape. When the bell means 2 is shaken, the rolling piece 2B as a striking member rolls and collides with the bell main body 2A to generate a warning sound.
The lower end of the connecting pin 5 is fixed to the upper end of the bell main body 2 </ b> A, and the ring 6 is attached to the through hole at the upper end of the connecting pin 5. The upper ends of the ring 6 and the connecting pin 5 are projected upward from the casing 3 so that the bear avoiding bell 1 can be attached to a required portion such as a rucksack through a string or a carabiner.

When the switching member 4 is pushed deeply into the casing 3 to approach the bell means 2, the magnet 11 embedded in the upper surface of the switching member 4 comes into contact with the lower end of the bell main body 2A, and the iron rolling piece 2B is moved by the magnetic force. The bell body 2A is magnetically attached and fixed. Thus, the state in which the interlocking piece 2B is fixed in the bell main body 2A by the magnet 11 is a warning sound stop state. In this state, even if the bell means 2 is shaken, no warning sound is generated. On the other hand, when the switching member 4 is pulled out from the casing 3 to the lower end position and separated from the bell main body 2A, the magnet 11 of the switching member 4 is separated from the lower end portion of the bell main body 2A (see FIGS. 1 and 2). . Thereby, the magnetized state of the rolling piece 2B by the magnet 11 is cancelled | released. The state shown in FIGS. 1 and 2 is a warning sound generation state. In this state, the interlocking piece 2B can freely roll in the bell main body 2A. Therefore, when the bell means 2 is shaken, the bell main body 2A The rolling pieces 2B collide with each other to generate a warning sound. That is, a warning sound is generated when the bear avoidance bell 1 swings. Switching between the warning sound generation state and the warning sound stop state is performed by the user of the bear avoidance bell 1 pushing the switching member 4 deeply into the casing 3 or pulling the switching member 4 downward from the state. It has come to be.
Further, as will be described in detail later, the bear avoidance bell 1 of this embodiment rotates the inner cylindrical member 12 and the outer cylindrical member 13 constituting the casing 3 relative to each other in the circumferential direction in a warning sound generation state. By doing so, the volume of the warning sound of the bear avoidance bell 1 can be adjusted.

The casing 3 is composed of an inner cylindrical member 12 and an outer cylindrical member 13 having a bottomed cylindrical shape, and the outer cylindrical member 13 is covered from above on the inner cylindrical member 12 whose opening is directed downward. It has been. A through hole 12a is formed in the center of the upper surface 12A of the inner cylindrical member 12, and a through hole 13a is also formed in the center of the upper surface 13A of the outer cylindrical member 13.
The bell means 2 is accommodated inside the inner cylindrical member 12, and the connecting pin 5 passes through the through hole 12 a of the inner cylindrical member 12 and the through hole 13 a of the outer cylindrical member 13, and the outside of the casing 3. Projects upward. As described above, the hanging ring 6 is attached to the upper end portion of the connecting pin 5.
Both the inner cylindrical member 12 and the outer cylindrical member 13 are made of synthetic resin, and four notches 12B and 13B extending in the axial direction are formed at equal circumferential positions in the cylindrical portion. That is, in the cylindrical portion of the inner cylindrical member 12, four cutout portions 12B as openings are formed, and four axial portions 12C are formed at adjacent positions thereof. The lower end portion of the inner cylindrical member 12 is an annular portion 12D that is continuous in the circumferential direction.

The outer cylindrical member 13 has the same configuration as the inner cylindrical member 12. That is, the cylindrical portion of the outer cylindrical member 13 is formed with four notches 13B serving as openings, and four axial portions 13C are formed at adjacent positions thereof. The lower end portion of the cylindrical member 13 is an annular portion 13D that is continuous in the circumferential direction.
As shown in FIG. 5, spline-like irregularities are formed in the axial direction over the entire inner peripheral surface of the annular portion 13 </ b> D of the outer cylindrical member 13, and on the other hand, 4 on the outer peripheral surface of the inner cylindrical member 12. The point-shaped minute protrusion 12E is formed in the location. The outer peripheral surface of the annular portion 12D of the inner cylindrical member 12 is fitted to the annular portion 13D of the outer cylindrical member 13, and each minute projection 12E is engaged with the concave portion at the opposite position. Therefore, in a natural state where the user does not operate the casing 3, the outer cylindrical member 13 and the inner cylindrical member 12 do not move relative to each other in the circumferential direction. On the other hand, when the user grips with a finger and applies a force to rotate the outer cylindrical member 13 and the inner cylindrical member 12 in the circumferential direction, the outer cylindrical member 13 is maintained with a slight frictional resistance. The inner cylindrical member 12 is relatively rotated in the circumferential direction.
The switching member 4 is slidably fitted to the inner peripheral surface on the lower side of the inner cylindrical member 12 including the annular portion 12D.

The switching member 4 is also formed in a bottomed cylindrical shape, and a columnar magnet 11 is embedded in a recess 4B formed in the center of the upper surface 4A. An annular groove 4C is formed in the outer peripheral portion on the upper side of the switching member 4, and the outer peripheral portion at the lower end of the switching member 4 is a flange portion 4D extending outward in the radial direction.
The outer diameter of the cylindrical portion of the switching member 4 is set to be slightly smaller than the inner diameter of the inner cylindrical member 12, so that the switching member 4 is slidable on the inner cylindrical member 12 from below. It is mated.
The axial dimension of the switching member 4 is set to be slightly longer than the distance from the lower end of the inner cylindrical member 12 to the lower end of the bell main body 2A. Therefore, when the user of the bear avoidance bell 1 pushes the switching member 4 deeply into the inner cylindrical member 12 from the lower side to approach the bell main body 2A, the upper surface 4A of the switching member 4 is flush with the upper surface 4A. The magnet 11 contacts the lower end of the bell body 2A (see FIG. 7). Then, the rolling piece 2B in the bell means 2 is magnetized by the magnet 11 and fixed to the inner surface of the bell main body 2A. In other words, since the warning sound is stopped, the warning sound is not generated from the bell means 2 even if the bell means 2 and the bear avoidance bell 1 are swung in the warning sound stop state shown in FIG. Yes.

On the other hand, when the user pulls the switching member 4 downward from the inner cylindrical member 12 and separates it from the main body 2 </ b> A from the warning sound stop state shown in FIG. 7, the annular groove 4 </ b> C of the switching member 4 Engages with the annular portion 12D (state shown in FIGS. 1 and 2). In this state, the magnet 11 of the switching member 4 is largely separated from the lower end of the bell main body 2A, and the magnetized state of the rolling piece 2B by the magnet 11 is released. That is, the bell means 2 is switched to a warning sound generation state for generating a warning sound.
1 and 2, the user compresses the upper surface 13 </ b> A of the outer cylindrical member 13 in the casing 3 and the flange portion 4 </ b> D, which is the lower surface of the switching member 4, from above and below with the finger from above and below. As a result, the lower end portion of the inner cylindrical member 12 is elastically deformed and expanded, whereby the annular groove 4C is detached from the annular portion 12D, and the switching member 4 is pushed deeply into the inner cylindrical member 12. Thereby, the magnet 11 of the switching member 4 comes into contact with the lower end portion of the bell main body 2A, and the rolling piece 2B is magnetically attached and fixed in the bell main body 2A. That is, it switches to the warning sound stop state shown in FIG.
As described above, in this embodiment, the switching member 4 is pushed deeply into the inner cylindrical member 12 of the casing 3 to approach the bell main body 2A, and the annular protrusion is drawn out from the inner cylindrical member 12 into the annular groove 4C. By switching to a state where 12B is engaged (a state separated from the bell main body 2A), it is possible to switch between a warning sound generation state where a warning sound is generated and a warning sound stop state where a warning sound is not generated.
An annular protrusion as a stopper 4E is formed on the upper side adjacent to the annular groove 4C, and the switching member 4 is prevented from dropping from the inner cylindrical member 12 by the stopper 4E coming into contact with the annular portion 12. It has become. That is, when the annular portion 12D is engaged with the annular groove 4C (the state shown in FIGS. 1 and 2), the switching member 4 is pulled out to the lowermost end with respect to the inner cylindrical member 12. This state is a warning sound generation state for generating a warning sound.

Furthermore, in the present embodiment, the bear avoidance bell is changed by changing the relative positions of the inner cylindrical member 12 and the outer cylindrical member 13 in the circumferential direction in the warning sound generation state shown in FIGS. The volume of the warning sound 1 can be adjusted.
That is, as described above, the cylindrical portions of the inner cylindrical member 12 and the outer cylindrical member 13 have four cutout portions 12B and 13B serving as openings and four axial portions 12C and 13C adjacent to the notches. Is formed.
As shown in FIGS. 1 and 4, the inner cylindrical member 12 and the switching member 4 engaged with the inner cylindrical member 12 are rotated relative to the outer cylindrical member 13 in the circumferential direction by a required amount, so that the inner cylindrical member is rotated. The four axial portions 12C of 12 are completely overlapped with the four axial portions 13C of the outer cylindrical member 13 without any deviation in the circumferential direction. In this state, each notch portion 12B of the inner cylindrical member 12 and each notch portion 13B of the outer cylindrical member 13 are overlapped with each other without deviation in the circumferential direction, and an opening formed by each notch portion 12B, 13B is formed. The amount of opening becomes the maximum. Therefore, as shown in FIGS. 1 and 4, the warning sound generated by the bell means 2 is maximized when the opening amount of the opening is maximized when the casing 3 is viewed as a whole.

On the other hand, when the inner tubular member 12 and the switching member 4 engaged with the inner tubular member 12 and the switching member 4 engaged with the inner tubular member 12 are rotated relative to the outer tubular member 13 in a circumferential direction from a state where the warning sound shown in FIGS. The notch 12B of the inner cylindrical member 12 is partially closed by the axial part 13C of the outer cylindrical member 13, and the notch of the outer cylindrical member 13 is cut by the axial part 12C of the inner cylindrical member 12. Part 13B is partially closed. That is, when it sees the casing 3 whole, the opening amount of four opening parts becomes small (refer FIG. 2, FIG. 6). Therefore, compared with the state shown in FIGS. 1 and 4, the volume when the bell means 2 is swung and a warning sound is generated is smaller in the state shown in FIGS. 2 and 6.
As described above, in this embodiment, in the alarm sound generation state, the inner cylindrical member 12 and the switching member 4 engaged with the inner cylindrical member 12 are rotated relative to the outer cylindrical member 13 in the circumferential direction. 1. It can be adjusted from a state where the volume of the warning sound shown in FIG. 4 is maximized to a state where the volume is smaller than that.

As described above, in the bear avoidance bell 1 according to the present embodiment, when switching between the warning sound generation state and the warning sound stop state, the user pushes the switching member 4 deeply into the inner cylindrical member 12 and the bell main body. The switching member 4 may be pulled out from the inner cylindrical member 12 to the descending end and separated from the bell main body 2A. This switching operation can be easily performed using the finger of one hand without the user visually confirming the bear avoidance bell 1. For this reason, for example, when a warning sound is annoying to other passers-by, such as trains or urban areas, or when a bear is likely to occur, a user wears a rucksack with a bear avoidance bell 1 attached. It is possible to easily switch between a warning sound generation state and a warning sound stop state by groping. Moreover, since the structure of the bear avoidance bell 1 of this embodiment is simple, it is possible to provide a bear avoidance bell 1 that is smaller and lighter than the conventional one.
Further, in this embodiment, the warning sound generated in the warning sound generation state can be adjusted from the maximum volume to a volume lower than the required volume, so that the situation at the site when using the bear avoidance bell 1 can be improved. Accordingly, the warning sound can be set to a suitable volume.

Next, FIGS. 8 to 10 show a second embodiment of the present invention. In the second embodiment, instead of the bell-shaped bell means 2 in the first embodiment, a bell means 2 including an acoustic one portion 22 and a pendulum-shaped hitting portion 23 is used.
That is, the bell means 2 includes an acoustic one portion 22 made of bowl-shaped non-magnetic metal and a rod-like hitting portion 23 made of a magnetic material (iron), and the upper end of the hitting portion 23 is connected to the connecting pin 5. The lower end is swingably attached. The upper end of the connection pin 5 protrudes upward through the through hole 22A at the top of the acoustic one portion 22 and the through holes 12a and 13a of the inner cylindrical member 12 and the outer cylindrical member 13, and this connection pin 5 A ring 6 is attached to the upper end of the ring.
The height of the lower end portion of the striking member 23 is maintained substantially the same as the height of the lower end portion of the acoustic one portion 22, and when the striking member 23 is swung, the lower end portion thereof becomes the acoustic one portion 22. A warning sound is generated by the collision (see FIGS. 8 and 9).
Other configurations are the same as those in the first embodiment described above, and the same member numbers are assigned to the members corresponding to those in the first embodiment. Even in the second embodiment having such a configuration, the same operation and effect as the first embodiment can be obtained.
In each of the above-described embodiments, the casing 3 includes the inner cylindrical member 12 and the outer cylindrical member 13, and the volume of the warning sound can be adjusted by rotating them relative to each other at a required angle in the circumferential direction. However, the casing 3 may have a configuration in which the outer cylindrical member 13 is omitted. That is, the casing 3 is configured only by the inner cylindrical member 12, and the volume adjustment function of the warning sound is omitted, and the casing 3 can be switched between the warning sound generation state and the warning stop state. With such a configuration, the bear avoidance bell 1 can be further reduced in size and weight as compared with the above-described embodiments.

Next, FIG. 11 shows still another embodiment of the present invention, and this embodiment has a configuration in which the casing 3 in each embodiment described above is omitted. That is, the bear avoidance bell 1 has a spherical bell means 2 similar to the embodiment of FIG. 1 and a support member 31 formed in a prism shape and connected at one end to the bell body 2A of the bell means 2. A switching member 4 is provided on the support member 31 so as to be swingable.
The bell means 2 includes a bell main body 2A made of a non-magnetic material and an iron rolling piece 2B made of a magnetic material. In this embodiment, the switching member 4 is a rod-like member, and a magnet 11 is connected to the tip (integral) of the switching member 4. The base (other end) of the switching member 4 is bent in an L shape, and the base is fitted into the bottomed hole of the support member 31. Thereby, the whole switching member 4 can be swung.
When the switching member 4 is swung to bring the magnet 11 closer to the bell body 2A, the iron rolling piece 2B is magnetized and fixed by the magnet 11. This state is a warning sound stop state (state indicated by a solid line). On the other hand, when the switching member 4 is swung to separate the magnet 11 from the bell main body 2, the magnetized state of the rolling piece 2B by the magnet 11 is released (a state indicated by an imaginary line). This state is a warning sound generation state. A coiled coupling tool 32 is coupled to the other end of the support member 32, and the bear avoidance bell 1 is suspended at a required location via the coiled coupling tool 32 and the like.
Also in this embodiment shown in FIG. 11, it is possible to obtain the same operation and effect as the above embodiments.
