The tooth portion 30 is formed so as to be fitted to the tooth portion 28 formed at the upper end of the holding member 5 as shown in FIG. 2B, but as shown in FIGS. The tooth portion 28 of the holding member 5 and the tooth portion 30 of the rotating cam 6 are formed at positions slightly deviated from the center.
More specifically, the positional relationship between the protrusion 29 and the tooth portion 30 in the rotating cam 6 is about half that of the one tooth portion 30 with respect to the positional relationship between the protrusion 27 and the tooth portion 28 in the holding member 5. It is shifted by an angle.
For this reason, as shown in FIGS. 2A and 2C, when the protrusion 27 of the holding member 5 and the protrusion 29 of the rotating cam 6 are vertically aligned, both the tooth portions 28 and 30 cannot be in close contact with each other. It has become.

本実施例における上記切換手段１０は、いわゆるノック式の回転カム機構となっており、上記筒状部材４の内部に設けた深溝２４、浅溝２５、カム斜面２６と、上記保持部材５のカム部５ｂに設けた突起２７および歯部２８と、上記回転カム６の突起２９、歯部３０、カム斜面３１と、該回転カム６を付勢するばね７とによって構成されている。
以下、この切換手段１０の動作とともに、熊避けベル１の使用方法について説明する。
まず、熊避けベル１を上記カラビナ９によってリュックサックやズボンのベルトループなどに装着すると、自重により上記音響ワン部２や打撃部３がカラビナ９の下方にぶら下がるようになっている。
つまり、上記カラビナ９には上記ワイヤー８を介して保持部材５が連結されているため、保持部材５はワイヤー８によってカラビナ９にぶら下がっている状態となっている。
一方、この保持部材５は上記回転カム６に下方から当接して、該回転カム６を下方から支持しており、さらにこの回転カム６はばね７に下方から当接して、該ばね７はその付勢力によって上記ケース１２ごと音響ワン部２および筒状部材４を下方から支持している。 The switching means 10 in this embodiment is a so-called knock-type rotating cam mechanism, and a deep groove 24, a shallow groove 25, a cam slope 26 provided inside the tubular member 4, and a cam of the holding member 5 are provided. A projection 27 and a tooth portion 28 provided on the portion 5 b, a projection 29 of the rotating cam 6, a tooth portion 30, a cam slope 31, and a spring 7 that biases the rotating cam 6.
Hereinafter, the usage of the bear avoidance bell 1 will be described together with the operation of the switching means 10.
First, when the bear avoidance bell 1 is attached to a rucksack or a belt loop of a pants by the carabiner 9, the acoustic one portion 2 and the hitting portion 3 are hung under the carabiner 9 by their own weight.
That is, since the holding member 5 is connected to the carabiner 9 via the wire 8, the holding member 5 is in a state of hanging from the carabiner 9 by the wire 8.
On the other hand, the holding member 5 abuts on the rotating cam 6 from below and supports the rotating cam 6 from below. Further, the rotating cam 6 abuts on a spring 7 from below, and the spring 7 The acoustic one part 2 and the cylindrical member 4 are supported from below by the biasing force together with the case 12.

次に、図２（ａ）に示す警告音発生状態について説明すると、この警告音発生状態において、上記回転カム６の突起２９は上記筒状部材４の深溝２４に係合するようになっている。
その結果、上記ばね７の付勢力によって回転カム６は下方に付勢されて保持部材５を下方に押圧するようになっており、また回転カム６のフランジ６ａ部が筒状部材４に形成された中径部２３と小径部２２との段差に当接することで、これ以上の下降が阻止されるようになっている。
この回転カム６によって下方に押圧された保持部材５は、筒状部材４に対して相対的に下方に位置しており、その結果図２（ａ）に示す前進位置に位置することとなる。
保持部材５が前進位置に位置すると、上記保持部材５の下方に連結された打撃部３の被収容部３ａが上記筒状部材４の大径部２１より下方に離脱するため、打撃部３は上記ワイヤー１１によって揺動が許容され、打撃部３が音響ワン部２に衝突することで警告音が発生されることとなる。
一方、この警告音発生状態において、上記回転カム６の突起２９は筒状部材４の深溝２４に係合し、また保持部材５の突起２７は常時深溝２４および浅溝２５に係合していることから、上記保持部材５の歯部２８と回転カム６の歯部３９とは密着せず、両歯部２８、３０の一部分同士だけが接触した状態となっている。 Next, the warning sound generation state shown in FIG. 2A will be described. In this warning sound generation state, the projection 29 of the rotating cam 6 is engaged with the deep groove 24 of the cylindrical member 4. .
As a result, the rotating cam 6 is urged downward by the urging force of the spring 7 to press the holding member 5 downward, and the flange 6a portion of the rotating cam 6 is formed on the cylindrical member 4. Further, by coming into contact with the step between the medium diameter portion 23 and the small diameter portion 22, further lowering is prevented.
The holding member 5 pressed downward by the rotating cam 6 is positioned relatively downward with respect to the cylindrical member 4, and as a result, is positioned at the forward movement position shown in FIG.
When the holding member 5 is positioned at the forward movement position, the accommodated portion 3a of the hitting portion 3 connected to the lower side of the holding member 5 is detached below the large-diameter portion 21 of the cylindrical member 4, so that the hitting portion 3 is Oscillation is allowed by the wire 11 and a warning sound is generated when the hitting portion 3 collides with the acoustic one portion 2.
On the other hand, in this warning sound generation state, the protrusion 29 of the rotating cam 6 is engaged with the deep groove 24 of the cylindrical member 4, and the protrusion 27 of the holding member 5 is always engaged with the deep groove 24 and the shallow groove 25. Therefore, the tooth portion 28 of the holding member 5 and the tooth portion 39 of the rotating cam 6 are not in close contact with each other, and only a part of both tooth portions 28 and 30 are in contact with each other.

そして、この図２（ａ）に示す警告音発生状態から図２（ｃ）に示す警告音停止状態とする場合、使用者は音響ワン部２を下方に向けて移動させて図２（ｂ）の状態とする。
音響ワン部２を下方に向けて移動させると、上記ケース１２が下方に移動して上記上記ばね７を下方に押圧し、その結果、上記ワイヤー８にぶら下げられた保持部材５の上方に接触している回転カム６との間で、ばね７が圧縮されることとなる。
換言すると、保持部材５はばね７の付勢力に抗して筒状部材４の内部を相対的に上方に移動し、最終的には図２（ｂ）に示すように保持部材５の上端部が上記筒状部材４のカム斜面２６の上端部より上方に突出するようになっている。
すると、それまで上記筒状部材４の深溝２４に突起２９が係合して回転が阻止されていた回転カム６は、該突起２９が深溝２４の上方に離脱することとなり、回転が許容されることとなる。
回転カム６は上記ばね７によって下方への付勢力が作用し、かつ回転カム６の歯部３０は、それまで密着していなかった上記保持部材５の歯部２８に沿って嵌合するように摺動するため、回転カム６は回転しながら下降することとなる。
図２（ｂ）は両歯部２８、３０が密着した状態を示しており、これにより回転カム６の突起２９は上記深溝２４に対して偏倚することとなり、カム斜面２６の阻止部分２６ａの上方に位置するようになっている。 When the warning sound generation state shown in FIG. 2 (a) is changed to the warning sound stop state shown in FIG. 2 (c), the user moves the acoustic one portion 2 downward and changes the state shown in FIG. 2 (b). State.
When the acoustic one portion 2 is moved downward, the case 12 moves downward and presses the spring 7 downward. As a result, the case 12 comes into contact with the upper side of the holding member 5 hung from the wire 8. The spring 7 is compressed between the rotating cam 6 and the rotating cam 6.
In other words, the holding member 5 moves relatively upward in the cylindrical member 4 against the urging force of the spring 7, and finally the upper end portion of the holding member 5 as shown in FIG. Projecting upward from the upper end of the cam slope 26 of the tubular member 4.
Then, the rotation cam 6 that has been prevented from rotating by the engagement of the projection 29 with the deep groove 24 of the cylindrical member 4 until then, the projection 29 is disengaged above the deep groove 24 and is allowed to rotate. It will be.
The rotating cam 6 is applied with a downward biasing force by the spring 7, and the tooth portion 30 of the rotating cam 6 is fitted along the tooth portion 28 of the holding member 5 that has not been in close contact so far. Because of sliding, the rotating cam 6 descends while rotating.
FIG. 2B shows a state in which both the tooth portions 28 and 30 are in close contact with each other, whereby the protrusion 29 of the rotating cam 6 is biased with respect to the deep groove 24 and above the blocking portion 26 a of the cam slope 26. It is supposed to be located in.

この図２（ｂ）の状態まで音響ワン部２が引き下げられ、その後使用者が音響ワン部２を手放すと、熊避けベル１は図２（ｃ）に示す警告音停止状態となる。
図２（ｂ）の状態から音響ワン部２を手放すと、ばね７の付勢力によって音響ワン部２が上方に付勢され、これにより上記回転カム６と保持部材５とは一体的に筒状部材４に対して相対的に下降することとなる。
このとき上記回転カム６の突起２９は、筒状部材４のカム斜面２６における阻止部分２６ａの上方に位置しているため、回転カム６が下降することにより、突起２９の下端に形成されたカム斜面３１が筒状部材４の上記阻止部分２６ａに当接することとなる。
その後、上記回転カム６にはばね７の付勢力が作用することから、上記突起２９のカム斜面３１は上記阻止部分２６ａに沿って摺動し、回転カム６は回転しながら下降する。
そして、突起２９がカム斜面２６における阻止部分２６ａと許容部分２６ｂとの境界に位置する段差２６ｃに当接すると、これ以上の回転カム６の回転が阻止されるとともに、上記突起２９は浅溝２５に係合しないようになっていることから、回転カム６はこれ以上下降しないようになっている。
このようにして回転カム６の下降が阻止された状態において、上記保持部材５は上記ワイヤー８によってぶら下げられていることから、上記回転カム６を下方から支持するようになっており、保持部材５は筒状部材４に対して上方に位置する後退位置で保持されるようになっている。
保持部材５を筒状部材４に対して後退位置で保持すると、上記保持部材５の下方に連結された打撃部３が筒状部材４に接近して、上記被収容部３ａが保持部材５の大径部２１に収容されることとなる。
これにより打撃部３は揺動が阻止され、該打撃部３が音響ワン部２に衝突することは無いので、警告音の発生が阻止されるようになっている。
一方、この警告音停止状態において、上記回転カム６の突起２９は筒状部材４の浅溝２５の上方で停止しており、また保持部材５の突起２７は常時深溝２４および浅溝２５に係合していることから、上記保持部材５の歯部２８と回転カム６の歯部３０とは密着しないようになっている。 When the acoustic one part 2 is pulled down to the state shown in FIG. 2B and the user then releases the acoustic one part 2, the bear avoidance bell 1 enters the warning sound stop state shown in FIG. 2C.
When the acoustic one portion 2 is released from the state of FIG. 2B, the acoustic one portion 2 is urged upward by the urging force of the spring 7, whereby the rotating cam 6 and the holding member 5 are integrally formed in a cylindrical shape. It will descend relative to the member 4.
At this time, since the protrusion 29 of the rotating cam 6 is positioned above the blocking portion 26 a on the cam slope 26 of the cylindrical member 4, the cam formed at the lower end of the protrusion 29 when the rotating cam 6 descends. The inclined surface 31 comes into contact with the blocking portion 26a of the cylindrical member 4.
Thereafter, since the urging force of the spring 7 acts on the rotating cam 6, the cam slope 31 of the projection 29 slides along the blocking portion 26a, and the rotating cam 6 descends while rotating.
When the protrusion 29 comes into contact with the step 26c located at the boundary between the blocking portion 26a and the allowable portion 26b on the cam inclined surface 26, further rotation of the rotating cam 6 is blocked and the protrusion 29 is formed in the shallow groove 25. Therefore, the rotating cam 6 is not lowered any further.
Since the holding member 5 is hung by the wire 8 in the state where the lowering of the rotating cam 6 is prevented in this way, the rotating cam 6 is supported from below, and the holding member 5 Is held in a retracted position located above the tubular member 4.
When the holding member 5 is held in the retracted position with respect to the cylindrical member 4, the striking portion 3 connected to the lower side of the holding member 5 approaches the cylindrical member 4, and the accommodated portion 3 a becomes the holding member 5. The large diameter portion 21 is accommodated.
As a result, the striking unit 3 is prevented from swinging, and the striking unit 3 does not collide with the acoustic one unit 2, so that the generation of a warning sound is prevented.
On the other hand, in the warning sound stop state, the protrusion 29 of the rotating cam 6 is stopped above the shallow groove 25 of the cylindrical member 4, and the protrusion 27 of the holding member 5 is always engaged with the deep groove 24 and the shallow groove 25. Therefore, the tooth portion 28 of the holding member 5 and the tooth portion 30 of the rotating cam 6 are not in close contact with each other.

そして図２（ｃ）の警告音停止状態から、再び図２（ａ）の警告音発生状態とするには、再度音響ワン部２を下方に引き下げればよい。
すると、図２（ｂ）とは異なるが、上記保持部材５の先端が再び小径部２２のカム斜面２６より上方に突出して回転カム６が回転し、回転カム６の歯部３０と保持部材５の歯部２８とが密着する。
その結果、回転カム６の突起２９は上記浅溝２５に対して偏倚し、カム斜面２６の許容部分２６ｂの上方に位置する。
その後使用者が音響ワン部２を手放すと、ばね７の付勢力により回転カム６が下降してカム斜面３１が上記カム斜面２６の許容部分２６ｂに当接するため、突起２９は回転カム６の回転に伴って深溝２４の位置まで移動する。
一方、回転カム６はばね７によって下方に付勢されていることから、上記突起２９が深溝２４の位置まで到達すると、ばね７の付勢力によって回転カム６は図２（ａ）に示す位置まで下降され、該回転カム６に押圧された保持部材５は筒状部材４に対して上記前進位置まで下降することとなる。
これにより、上記保持部材５の収容部から打撃部３の被収容部３ａが離脱し、打撃部３は揺動可能となるため、上記音響ワン部２に衝突して警告音を発生させることが可能となる。 Then, in order to change from the warning sound stop state of FIG. 2 (c) to the warning sound generation state of FIG. 2 (a) again, the acoustic one portion 2 may be lowered again.
Then, although different from FIG. 2B, the tip of the holding member 5 again protrudes upward from the cam slope 26 of the small diameter portion 22 to rotate the rotating cam 6, and the tooth portion 30 of the rotating cam 6 and the holding member 5. The tooth portion 28 closely contacts.
As a result, the protrusion 29 of the rotating cam 6 is biased with respect to the shallow groove 25 and is located above the allowable portion 26b of the cam slope 26.
Thereafter, when the user releases the acoustic one portion 2, the rotating cam 6 is lowered by the biasing force of the spring 7, and the cam inclined surface 31 comes into contact with the allowable portion 26 b of the cam inclined surface 26, so that the protrusion 29 rotates the rotating cam 6. Along with this, it moves to the position of the deep groove 24.
On the other hand, since the rotating cam 6 is urged downward by the spring 7, when the protrusion 29 reaches the position of the deep groove 24, the rotating cam 6 is moved to the position shown in FIG. The holding member 5 that is lowered and pressed by the rotating cam 6 is lowered to the advance position with respect to the tubular member 4.
Thereby, the to-be-accommodated part 3a of the striking part 3 is detached from the accommodating part of the holding member 5, and the striking part 3 can swing, so that it can collide with the acoustic one part 2 and generate a warning sound. It becomes possible.

上記実施例における熊避けベル１によれば、上記警告音発生状態または警告音停止状態とする際に、使用者はこの熊避けベル１の音響ワン部２を下方に移動させればよいため、この切り換え操作を片手で操作することができ、また使用者は熊避けベル１がリュックサックに装着されるなど視認できない状態であっても、これを操作することができる。
これにより、例えば電車や市街地など、警告音が他の通行人等に対して迷惑となる場合や、熊が発生しそうな地域に侵入した場合において、使用者はいちいちリュックサックを下ろす必要がなく、手探りで警告音発生状態または警告音停止状態に切り換えることができる。 According to the bear avoidance bell 1 in the above embodiment, when the warning sound is generated or the alarm sound is stopped, the user only has to move the acoustic one portion 2 of the bear avoidance bell 1 downward. This switching operation can be operated with one hand, and the user can operate this even when the bear avoiding bell 1 is not visible, such as being attached to the rucksack.
This makes it unnecessary for the user to take down the rucksack every time, for example, when a warning sound becomes annoying to other passers-by, such as trains or urban areas, or when a bear is likely to occur, It can be switched to a warning sound generation state or a warning sound stop state by groping.

なお、上記実施例における上記切換手段１０は、上記回転カム６を用いた回転カム機構となっているが、その他、上記保持部材６または筒状部材４のいずれか一方に係合突起を設け、他方に該係合突起が係合する被係合部を形成し、さらにこの係合突起と被係合部との係合状態を解除する解除手段を備えた機構であっても良い。
例えば、上記保持部材６を筒状部材４に対して後退位置に位置させた際に係合突起と被係合部とが係合するようにし、その状態で上記解除手段がこれらの係合状態を解除すると、上記ばね７の付勢力によって保持部材６が筒状部材４に対して下降した前進位置に位置させることができる。
その他の切換手段１０として、筒状部材の内面と保持部材の外面にそれぞれらせん状のカム斜面を設け、上記保持部材をこのカム斜面に沿って所定角度回転させることにより、保持部材が筒状部材に対して上下に移動するようにした構成も考えられる。 In addition, although the said switching means 10 in the said Example becomes a rotation cam mechanism using the said rotation cam 6, an engagement protrusion is provided in any one of the said holding member 6 or the cylindrical member 4, Alternatively, a mechanism may be provided that includes a portion to be engaged with which the engagement protrusion is engaged, and a release unit that releases the engagement state between the engagement protrusion and the engagement portion.
For example, when the holding member 6 is positioned in the retracted position with respect to the cylindrical member 4, the engaging protrusion and the engaged portion are engaged, and in this state, the releasing means is in the engaged state. When the is released, the holding member 6 can be positioned at the advanced position lowered with respect to the tubular member 4 by the biasing force of the spring 7.
As the other switching means 10, a helical cam slope is provided on each of the inner surface of the cylindrical member and the outer surface of the holding member, and the holding member is rotated by a predetermined angle along the cam slope, whereby the holding member becomes the cylindrical member. A configuration is also conceivable that moves up and down.
