Description

本発明は、トリガースイッチに関する。 The present invention relates to a trigger switch.

特許文献１は、トリガーをオフ位置でロックできるロック機構を開示している。このロック機構は、トリガーの内部に固定されたロック板に設けられたスロットに挿通されたロックピンを有し、ロックピンの広軸部がスロットに係合することにより、トリガーをオフ位置にロックし、ロックピンを押して、広軸部をスロットから外に押し出すことにより、トリガーのロックを解除する。 Patent Document 1 discloses a locking mechanism that can lock the trigger in the off position. This lock mechanism has a lock pin inserted into a slot provided in a lock plate fixed inside the trigger, and the wide shaft portion of the lock pin engages with the slot to lock the trigger in the off position. Then, push the lock pin to push the wide shaft part out of the slot to unlock the trigger.

米国特許第６８１２４２５号明細書U.S. Pat. No. 6,812,425

特許文献１のロック機構は、トリガーがオフ位置でロックされている状態で、無理にトリガーをオンしようとすると、ロックピンとスロットが係合している部分に大きな力が加わる。このため、トリガースイッチが破損する可能性がある。
特許文献１では、通常はプラスチックなどの強度が比較的低い材料で形成されているトリガーにスロットを直接形成するのではなく、強度が比較的高い金属で形成されたロック板にスロットを設け、ロック板をトリガーに固定する構成とすることで、破損を防いでいる。しかし、このような構成とすると、トリガースイッチの製造コストが高くなる。
本発明は、このような課題を解決することを目的とする。 In the lock mechanism of Patent Document 1, if the trigger is forcibly turned on while the trigger is locked in the off position, a large force is applied to the portion where the lock pin and the slot are engaged. Therefore, the trigger switch may be damaged.
In Patent Document 1, instead of directly forming a slot on a trigger usually made of a material having a relatively low strength such as plastic, a slot is provided on a lock plate made of a metal having a relatively high strength to lock the slot. Damage is prevented by fixing the plate to the trigger. However, such a configuration increases the manufacturing cost of the trigger switch.
An object of the present invention is to solve such a problem.

本発明に係るトリガースイッチは、オフ位置及びオン位置の間を移動可能なスイッチ操作部材と、オフロック位置及び解除位置の間を移動可能なロック操作部材と、阻止位置、許可可能位置及び許可位置の間を移動可能な阻止部材とを備える。前記阻止部材は、前記阻止位置に位置するとき、前記スイッチ操作部材が前記オン位置に移動するのを阻止する。前記阻止部材は、前記許可位置に位置するとき、前記スイッチ操作部材が前記オン位置に移動するのを許可する。前記阻止部材は、前記阻止位置に位置するとき、前記ロック操作部材を前記オフロック位置から前記解除位置に移動させると、前記許可可能位置に移動する。前記阻止部材は、前記許可可能位置に位置するとき、前記スイッチ操作部材を前記オフ位置から前記オン位置に向けて移動させると、前記許可位置に移動する。
前記阻止部材は、前記阻止位置に位置するとき、前記スイッチ操作部材が前記オフ位置から前記オン位置へ向けて移動すると、前記スイッチ操作部材に当接して、前記スイッチ操作部材の前記オン位置への移動を阻止してもよい。前記阻止部材は、前記阻止位置に位置するとき、前記ロック操作部材が前記オフロック位置から前記解除位置に移動すると、前記ロック操作部材に押されて、前記許可可能位置に移動してもよい。前記阻止部材は、前記許可可能位置に位置するとき、前記スイッチ操作部材が前記オフ位置から前記オン位置へ向けて移動すると、前記スイッチ操作部材に押されて、前記許可位置に移動してもよい。
前記許可可能位置は、前記阻止位置及び前記許可位置の間にあってもよい。
前記スイッチ操作部材は、所定の軸を中心として回動することにより、前記オフ位置及び前記オン位置の間を移動してもよい。前記阻止部材は、前記軸に対して略垂直な方向に平行移動することにより、前記阻止位置、前記許可可能位置及び前記許可位置の間を移動してもよい。
前記スイッチ操作部材は、更に、オンロック解除位置に移動可能であってもよい。前記ロック操作部材は、更に、オンロック位置に移動可能であってもよい。前記ロック操作部材は、前記オンロック位置に位置するとき、前記スイッチ操作部材が前記オン位置から前記オフ位置に移動するのを阻止してもよい。前記ロック操作部材は、前記解除位置に位置するとき、前記スイッチ操作部材が前記オン位置から前記オフ位置に移動するのを許可してもよい。前記スイッチ操作部材は、前記オン位置に位置するとき、前記ロック操作部材が前記オンロック位置から前記解除位置に移動するのを阻止してもよい。前記スイッチ操作部材は、前記オンロック解除位置に位置するとき、前記ロック操作部材が前記オンロック位置から前記解除位置に移動するのを許可してもよい。 The trigger switch according to the present invention includes a switch operating member that can move between the off position and the on position, a lock operating member that can move between the off-lock position and the unlocking position, and a blocking position, a permitting position, and a permitting position. It is provided with a blocking member that can move between them. The blocking member prevents the switch operating member from moving to the on position when it is located at the blocking position. The blocking member allows the switch operating member to move to the on position when located in the permitted position. When the blocking member is located at the blocking position, when the locking operating member is moved from the off-lock position to the unlocking position, the blocking member moves to the permitted position. When the blocking member is located at the permitted position, when the switch operating member is moved from the off position to the on position, the blocking member moves to the permitted position.
When the blocking member is located at the blocking position, when the switch operating member moves from the off position to the on position, the blocking member comes into contact with the switch operating member and moves to the on position of the switch operating member. You may block the movement. When the blocking member is located at the blocking position, when the locking operating member moves from the off-locking position to the unlocking position, the blocking member may be pushed by the locking operating member and moved to the permitted position. When the blocking member is located at the permitted position, when the switch operating member moves from the off position to the on position, the blocking member may be pushed by the switch operating member and moved to the permitted position. ..
The permitted position may be between the blocking position and the permitted position.
The switch operating member may move between the off position and the on position by rotating around a predetermined axis. The blocking member may move between the blocking position, the permitted position and the permitted position by translating in a direction substantially perpendicular to the axis.
The switch operating member may be further movable to the on-lock release position. The lock operating member may also be movable to the on-lock position. When the lock operating member is located at the on-lock position, the switch operating member may prevent the switch operating member from moving from the on position to the off position. The lock operating member may allow the switch operating member to move from the on position to the off position when located in the unlocked position. When the switch operating member is located at the on position, the switch operating member may prevent the lock operating member from moving from the on-lock position to the unlocking position. When the switch operating member is located at the on-lock release position, the switch operating member may be allowed to move from the on-lock position to the release position.

ロック操作部材が阻止部材を許可位置まで移動させるのではなく、許可可能位置まで移動させ、その後、スイッチ操作部材が阻止部材を許可可能位置から許可位置に移動させるので、阻止位置から許可位置までの阻止部材の移動量を大きくすることができる。これにより、スイッチ操作部材の移動を阻止するため、阻止位置に位置する阻止部材とスイッチ操作部材とが当接する部分の面積を大きくすることができる。このため、阻止部材やスイッチ操作部材を強度が比較的低い材料で形成しても、破損を防止することができ、トリガースイッチの製造コストを抑えることができる。 The lock operating member does not move the blocking member to the permitted position, but moves it to the permitted position, and then the switch operating member moves the blocking member from the permitted position to the permitted position, so that the blocking position is moved to the permitted position. The amount of movement of the blocking member can be increased. As a result, since the movement of the switch operating member is blocked, the area of the portion where the blocking member located at the blocking position and the switch operating member abut can be increased. Therefore, even if the blocking member and the switch operating member are made of a material having a relatively low strength, damage can be prevented and the manufacturing cost of the trigger switch can be suppressed.

図１に示すように、トリガースイッチ１０は、本体１２、作動部材１３、スイッチ操作部材１４、ロック操作部材１５、ワッシャー１７、付勢部材８４及び８５などを備える。
本体１２は、固定接片と可動接片との対を内蔵している。
作動部材１３は、本体１２に固定され、本体１２に対し、所定の範囲内でＣ−Ｄ方向に平行移動可能に構成されている。Ｃ−Ｄ方向は、例えば、軸９４に対して略垂直な方向である。本体１２内の可動切片は、作動部材１３の移動に伴って移動する。作動部材１３がＣ方向に移動すると、可動接片が固定接片と接触し、電気的に導通する。この状態を「オン状態」と呼ぶ。作動部材１３がＤ方向に移動すると、可動接片が固定接片から離間し、電気的に絶縁する。この状態を「オフ状態」と呼ぶ。
スイッチ操作部材１４（例えばトリガー）は、例えばプラスチックなどで一体に形成されている。スイッチ操作部材１４は、本体１２に固定され、本体１２に対し、所定の範囲内でＡ−Ｂ方向に回動可能に構成されている。Ａ−Ｂ方向は、軸９４を中心とする周回方向である。作動部材１３は、スイッチ操作部材１４の回動に伴って移動する。スイッチ操作部材１４がＡ方向に回動すると、作動部材１３がＣ方向に移動する。スイッチ操作部材１４がＢ方向に回動すると、作動部材１３がＤ方向に移動する。スイッチ操作部材１４がＢ方向に回動してオフ状態となったときの位置を「オフ位置」と呼ぶ。スイッチ操作部材１４がＡ方向に回動してオン状態となったとき位置を「オン位置」と呼ぶ。なお、スイッチ操作部材１４は、使用者が複数の指をかけることができる大きさである。これにより、指一本で操作する場合と比べて操作性が向上する。また、軸９４から比較的遠い位置に力を加えることができるので、小さい力で操作することができる。
付勢部材８４（例えばコイルばね）は、本体１２とスイッチ操作部材１４との間に配置され、スイッチ操作部材１４を本体１２に対してＢ方向へ（すなわち、オフ位置へ向けて）付勢している。
ロック操作部材１５（例えばロックボタン）は、本体１２に固定され、本体１２に対し、所定の範囲内でＥ−Ｆ方向に移動可能に構成されている。Ｅ−Ｆ方向は、例えば、軸９４に対して略平行な方向である。ロック操作部材１５は、スイッチ操作部材１４の回動を規制する。ロック操作部材１５がＦ方向の所定の位置にあるとき、スイッチ操作部材１４は、オフ位置からオン位置に移動することができない。ロック操作部材１５のこのときの位置を「オフロック位置」と呼ぶ。ロック操作部材１５をオフロック位置からＥ方向に移動させると、スイッチ操作部材１４は、オン位置に移動できるようになる。ロック操作部材１５のこのときの位置を「解除位置」と呼ぶ。ロック操作部材１５を解除位置から更にＥ方向に移動させると、スイッチ操作部材１４は、逆に、オン位置からオフ位置に移動することができなくなる。ロック操作部材１５のこのときの位置を「オンロック位置」と呼ぶ。
ワッシャー１７は、略円板状であり、中央に略長方形状の孔を有する。ロック操作部材１５の板部５３（図２参照）がこの孔を通る。
付勢部材８５（例えばコイルばね）は、ロック操作部材１５のボタン部５１（図２参照）とワッシャー１７との間に配置され、ロック操作部材１５を本体１２に対してＦ方向へ（すなわち、オフロック位置へ向けて）付勢している。 As shown in FIG. 1, the trigger switch 10 includes a main body 12, an operating member 13, a switch operating member 14, a lock operating member 15, a washer 17, and urging members 84 and 85.
The main body 12 has a built-in pair of a fixed contact piece and a movable contact piece.
The operating member 13 is fixed to the main body 12 and is configured to be able to translate with respect to the main body 12 in the CD direction within a predetermined range. The CD direction is, for example, a direction substantially perpendicular to the axis 94. The movable section in the main body 12 moves with the movement of the operating member 13. When the operating member 13 moves in the C direction, the movable contact piece comes into contact with the fixed contact piece and becomes electrically conductive. This state is called the "on state". When the operating member 13 moves in the D direction, the movable contact piece is separated from the fixed contact piece and electrically insulated. This state is called the "off state".
The switch operating member 14 (for example, a trigger) is integrally formed of, for example, plastic. The switch operating member 14 is fixed to the main body 12 and is configured to be rotatable in the AB direction within a predetermined range with respect to the main body 12. The AB direction is a circumferential direction centered on the axis 94. The operating member 13 moves with the rotation of the switch operating member 14. When the switch operating member 14 rotates in the A direction, the operating member 13 moves in the C direction. When the switch operating member 14 rotates in the B direction, the operating member 13 moves in the D direction. The position when the switch operating member 14 rotates in the B direction and is turned off is called an "off position". The position when the switch operating member 14 rotates in the A direction and is turned on is called an "on position". The switch operating member 14 has a size that allows the user to put a plurality of fingers on it. As a result, the operability is improved as compared with the case of operating with one finger. Further, since the force can be applied to a position relatively far from the shaft 94, the operation can be performed with a small force.
The urging member 84 (for example, a coil spring) is arranged between the main body 12 and the switch operating member 14, and urges the switch operating member 14 in the B direction (that is, toward the off position) with respect to the main body 12. ing.
The lock operation member 15 (for example, a lock button) is fixed to the main body 12 and is configured to be movable in the EF direction within a predetermined range with respect to the main body 12. The EF direction is, for example, a direction substantially parallel to the axis 94. The lock operating member 15 regulates the rotation of the switch operating member 14. When the lock operating member 15 is in a predetermined position in the F direction, the switch operating member 14 cannot move from the off position to the on position. The position of the lock operating member 15 at this time is referred to as an "off-lock position". When the lock operating member 15 is moved from the off-lock position in the E direction, the switch operating member 14 can be moved to the on position. The position of the lock operating member 15 at this time is referred to as a "release position". When the lock operating member 15 is further moved in the E direction from the release position, the switch operating member 14 cannot be moved from the on position to the off position. The position of the lock operating member 15 at this time is referred to as an "on-lock position".
The washer 17 has a substantially disk shape and has a substantially rectangular hole in the center. The plate portion 53 (see FIG. 2) of the lock operating member 15 passes through this hole.
The urging member 85 (for example, a coil spring) is arranged between the button portion 51 (see FIG. 2) of the lock operating member 15 and the washer 17, and the lock operating member 15 is placed in the F direction (that is, with respect to the main body 12) with respect to the main body 12. It is urging (towards the off-lock position).

図２に示すように、ロック操作部材１５は、ボタン部５１、鍔部５２、板部５３，５５、斜行部５４、爪部５６などを有する。
ボタン部５１及び鍔部５２は、例えばプラスチックなどで一体に形成されている。
ボタン部５１は、略円柱形状である。使用者がボタン部５１を押すことにより、ロック操作部材１５がＥ方向に移動する。
鍔部５２は、略円環板状であり、ボタン部５１と略同軸で、ボタン部５１の底部の周囲に設けられている。鍔部５２は、スイッチ操作部材１４の庇部４６（図３参照。）と係合することにより、オンロックを実現する。
板部５３、斜行部５４、板部５５及び爪部５６は、例えば金属板などで一体に形成されている。
板部５３は、略長方形板状である。板部５３は、第一端がボタン部５１に嵌合し、ボタン部５１から略Ｅ方向へ向けて延びている。
斜行部５４は、略長方形板状であり、幅が板部５３とほぼ同じである。斜行部５４は、第一端が板部５３の第二端に連続して、Ｅ方向に対してＣ方向に傾いた方向へ向けて延びている。
板部５５は、略長方形板状であり、幅が斜行部５４よりも大きい。板部５５は、第一端が斜行部５４の第二端に連続して、略Ｅ方向へ向けて延びている。
爪部５６は、略長方形板状である。爪部５６は、第一端が板部５５の他端に連続して、略Ａ方向へ向けて延びている。爪部５６は、ロック操作部材１５がＦ方向へ抜け出すのを防ぐ。 As shown in FIG. 2, the lock operation member 15 includes a button portion 51, a flange portion 52, plate portions 53, 55, a skew portion 54, a claw portion 56, and the like.
The button portion 51 and the collar portion 52 are integrally formed of, for example, plastic.
The button portion 51 has a substantially cylindrical shape. When the user presses the button portion 51, the lock operation member 15 moves in the E direction.
The collar portion 52 has a substantially annular plate shape, is substantially coaxial with the button portion 51, and is provided around the bottom portion of the button portion 51. The collar portion 52 realizes on-lock by engaging with the eaves portion 46 (see FIG. 3) of the switch operating member 14.
The plate portion 53, the skew portion 54, the plate portion 55, and the claw portion 56 are integrally formed of, for example, a metal plate.
The plate portion 53 has a substantially rectangular plate shape. The plate portion 53 has a first end fitted to the button portion 51 and extends from the button portion 51 in the substantially E direction.
The oblique portion 54 has a substantially rectangular plate shape, and has substantially the same width as the plate portion 53. The oblique portion 54 has a first end continuous with the second end of the plate portion 53 and extends in a direction inclined in the C direction with respect to the E direction.
The plate portion 55 has a substantially rectangular plate shape, and its width is larger than that of the oblique portion 54. The plate portion 55 has a first end continuous with the second end of the oblique portion 54 and extends in the substantially E direction.
The claw portion 56 has a substantially rectangular plate shape. The claw portion 56 has a first end continuous with the other end of the plate portion 55 and extends in the substantially A direction. The claw portion 56 prevents the lock operating member 15 from coming out in the F direction.

図３に示すように、スイッチ操作部材１４は、上面部４１、側面部４２、貫通穴４３〜４５、庇部４６などを有する。
上面部４１は、略波形曲面板状である。使用者が上面部４１を押すことにより、スイッチ操作部材１４がＡ方向に回動する。
側面部４２は、軸９４に対して略垂直な略平板状である。第一の側面部４２は、上面部４１のＦ側の縁から略Ａ方向へ向けて延びている。第二の側面部４２（不図示）は、上面部４１のＥ側の縁から略Ａ方向へ向けて延びている。
貫通穴４３〜４５は、それぞれの側面部４２を貫通する穴である。
貫通穴４３は、本体１２の凸部２１（図４参照）と係合して、スイッチ操作部材１４の回動軸を形成する。
貫通穴４４は、作動部材１３の凸部３１（図４参照）と係合して、スイッチ操作部材１４の回動を、作動部材１３に伝達する。
貫通穴４５は、ロック操作部材１５を通すための穴である。第一の側面部４２に設けられた貫通穴４５をロック操作部材１５の板部５３が通り、第二の側面部４２に設けられた貫通穴４５をロック操作部材１５の板部５５及び爪部５６が通る。このため、二つの貫通穴４５の位置は、ずれている。また、貫通穴４５は、スイッチ操作部材１４が回動してもロック操作部材１５と干渉しないように比較的広く構成されている。
庇部４６は、第一の側面部４２からＦ方向に離れた位置に配置されている。庇部４６は、ロック操作部材１５の鍔部５２と係合することにより、オンロックを実現する。 As shown in FIG. 3, the switch operating member 14 has an upper surface portion 41, a side surface portion 42, through holes 43 to 45, an eaves portion 46, and the like.
The upper surface portion 41 has a substantially corrugated curved plate shape. When the user pushes the upper surface portion 41, the switch operating member 14 rotates in the A direction.
The side surface portion 42 has a substantially flat plate shape substantially perpendicular to the shaft 94. The first side surface portion 42 extends in the substantially A direction from the F-side edge of the upper surface portion 41. The second side surface portion 42 (not shown) extends from the E-side edge of the upper surface portion 41 in the substantially A direction.
The through holes 43 to 45 are holes that penetrate the respective side surface portions 42.
The through hole 43 engages with the convex portion 21 (see FIG. 4) of the main body 12 to form a rotation shaft of the switch operating member 14.
The through hole 44 engages with the convex portion 31 (see FIG. 4) of the operating member 13 to transmit the rotation of the switch operating member 14 to the operating member 13.
The through hole 45 is a hole for passing the lock operation member 15. The plate portion 53 of the lock operation member 15 passes through the through hole 45 provided in the first side surface portion 42, and the plate portion 55 and the claw portion of the lock operation member 15 pass through the through hole 45 provided in the second side surface portion 42. 56 passes. Therefore, the positions of the two through holes 45 are misaligned. Further, the through hole 45 is relatively wide so as not to interfere with the lock operation member 15 even if the switch operation member 14 rotates.
The eaves portion 46 is arranged at a position separated from the first side surface portion 42 in the F direction. The eaves portion 46 realizes on-lock by engaging with the collar portion 52 of the lock operation member 15.

図４に示すように、トリガースイッチ１０は、更に、阻止部材１６、付勢部材８６などを備える。
本体１２は、左右に突出した略円柱形状の凸部２１を有する。
作動部材１３は、左右に突出した略円柱形条の凸部３１を有する。
阻止部材１６は、本体１２に固定され、本体１２に対して、所定の範囲内でＧ−Ｈ方向に平行移動可能に構成されている。Ｇ−Ｈ方向は、例えば、軸９４に対して略垂直な方向である。阻止部材１６は、当接部６１〜６３を有する。当接部６１及び６２は、スイッチ操作部材１４と当接する。当接部６３（図５参照）は、ロック操作部材１５と当接する。
阻止部材１６がＨ方向の所定の位置にあるとき、スイッチ操作部材１４をオフ位置からオン位置へ向けて回動させようとすると、当接部６１がスイッチ操作部材１４の当接部４７（図７参照）に当接して、スイッチ操作部材１４の回動を阻止する。阻止部材１６のこのときの位置を「阻止位置」と呼ぶ。阻止部材１６を阻止位置からＧ方向に移動させると、スイッチ操作部材１４をオフ位置からオン位置へ向けて回動させようとしても、当接部６１がスイッチ操作部材１４の当接部４７に当接しなくなり、スイッチ操作部材１４がオン位置に移動できるようになる。阻止部材１６のこのときの位置を「許可位置」と呼ぶ。
付勢部材８６は、阻止部材１６と本体１２との間に配置され、阻止部材１６を本体１２に対してＨ方向へ（すなわち阻止位置へ向けて）付勢している。 As shown in FIG. 4, the trigger switch 10 further includes a blocking member 16, an urging member 86, and the like.
The main body 12 has a substantially cylindrical convex portion 21 protruding to the left and right.
The operating member 13 has a convex portion 31 of a substantially cylindrical strip protruding to the left and right.
The blocking member 16 is fixed to the main body 12 and is configured to be able to translate with respect to the main body 12 in the GH direction within a predetermined range. The GH direction is, for example, a direction substantially perpendicular to the axis 94. The blocking member 16 has contact portions 61 to 63. The contact portions 61 and 62 come into contact with the switch operating member 14. The contact portion 63 (see FIG. 5) comes into contact with the lock operating member 15.
When the blocking member 16 is in a predetermined position in the H direction and the switch operating member 14 is to be rotated from the off position to the on position, the abutting portion 61 causes the abutting portion 47 of the switch operating member 14 (FIG. 7) to prevent the switch operating member 14 from rotating. The position of the blocking member 16 at this time is referred to as a "blocking position". When the blocking member 16 is moved from the blocking position in the G direction, the contact portion 61 hits the contact portion 47 of the switch operating member 14 even if the switch operating member 14 is to be rotated from the off position to the on position. The switch operating member 14 can be moved to the on position without being in contact with the switch operating member 14. The position of the blocking member 16 at this time is referred to as a "permitted position".
The urging member 86 is arranged between the blocking member 16 and the main body 12, and urges the blocking member 16 in the H direction (that is, toward the blocking position) with respect to the main body 12.

図５に示すように、ロック操作部材１５がオフロック位置に位置するとき、阻止部材１６は、付勢部材８６によってＨ方向へ向けて付勢され、阻止位置に位置する。
図６に示すように、ロック操作部材１５をＥ方向に移動させると、斜行部５４が当接部６３に当接して阻止部材１６をＧ方向に押す。 As shown in FIG. 5, when the lock operating member 15 is located in the off-lock position, the blocking member 16 is urged in the H direction by the urging member 86 and is located in the blocking position.
As shown in FIG. 6, when the lock operating member 15 is moved in the E direction, the oblique portion 54 abuts on the abutting portion 63 and pushes the blocking member 16 in the G direction.

図７に示すように、使用者がスイッチ操作部材１４を押していない状態において、スイッチ操作部材１４は、付勢部材８４によってＢ方向へ付勢され、オフ位置に位置する。また、ロック操作部材１５がオフロック位置に位置するとき、阻止部材１６は、付勢部材８６によってＨ方向へ付勢され、阻止位置に位置する。
この状態で、使用者がスイッチ操作部材１４を押すと、図８に示すように、スイッチ操作部材１４がＡ方向へ向けて回動するが、当接部４７が当接部６１に当接して、回動が阻止されるので、スイッチ操作部材１４は、オン位置に到達できない。したがって、オフ状態が維持される。
留意すべき点は、当接部４７と当接部６１とが当接する部分の面積が大きいことである。上述したようにスイッチ操作部材１４が比較的大きいので、オフロック状態であるにもかかわらず使用者が無理にオン状態にしようとすると、スイッチ操作部材１４に大きな力が加わる場合がある。当接部４７と当接部６１とが当接する部分の面積が大きいので、単位面積当りに加わる力が小さくなり、スイッチ操作部材１４及び阻止部材１６が破損するのを防ぐことができる。
また、当接部４７と当接部６１とが当接する部分は、軸９４から比較的遠い位置に位置する。したがって、テコの原理により、当接部４７及び６１に加わる力が小さくなり、スイッチ操作部材１４及び阻止部材１６が破損するのを防ぐことができる。 As shown in FIG. 7, when the user does not press the switch operating member 14, the switch operating member 14 is urged in the B direction by the urging member 84 and is located in the off position. Further, when the lock operating member 15 is located at the off-lock position, the blocking member 16 is urged in the H direction by the urging member 86 and is positioned at the blocking position.
When the user pushes the switch operating member 14 in this state, the switch operating member 14 rotates in the A direction as shown in FIG. 8, but the contact portion 47 comes into contact with the contact portion 61. Since the rotation is blocked, the switch operating member 14 cannot reach the on position. Therefore, the off state is maintained.
It should be noted that the area of the portion where the abutting portion 47 and the abutting portion 61 abut is large. As described above, since the switch operating member 14 is relatively large, if the user forcibly tries to turn it on even though it is in the off-lock state, a large force may be applied to the switch operating member 14. Since the area of the portion where the abutting portion 47 and the abutting portion 61 abut is large, the force applied per unit area becomes small, and it is possible to prevent the switch operating member 14 and the blocking member 16 from being damaged.
Further, the portion where the contact portion 47 and the contact portion 61 abut is located at a position relatively far from the shaft 94. Therefore, according to the principle of leverage, the force applied to the contact portions 47 and 61 is reduced, and it is possible to prevent the switch operating member 14 and the blocking member 16 from being damaged.

使用者がロック操作部材１５を押して、ロック操作部材１５を解除位置に移動させると、図９に示すように、阻止部材１６がＧ方向へ移動する。阻止部材１６のこのときの位置を「許可可能位置」と呼ぶ。
この状態で、使用者がスイッチ操作部材１４を押すと、図１０に示すように、当接部４８が当接部６２に当接して、阻止部材１６をＧ方向へ更に移動させる。これにより、阻止部材１６が許可位置まで到達し、図１１に示すように、スイッチ操作部材１４がオン位置に到達できるようになる。
留意すべき点は、仮に、阻止部材１６が許可可能位置から移動しなかったとすると、当接部４７が当接部６１に当接して、スイッチ操作部材１４がオン位置に到達できない可能性があることである。当接部４７と当接部６１とが当接する部分の面積を大きくしたことにより、阻止部材１６が阻止位置から許可位置に到達するまでに移動しなければならない距離が大きくなる。このため、ロック操作部材１５の操作によって阻止部材１６が移動する距離が足りない場合がある。そのような場合であっても、当接部４８が当接部６２に当接して阻止部材１６をＧ方向へ更に移動させることにより、阻止部材１６が確実に許可位置に到達し、オフロックが解除される。 When the user pushes the lock operation member 15 to move the lock operation member 15 to the release position, the blocking member 16 moves in the G direction as shown in FIG. The position of the blocking member 16 at this time is referred to as an "permissible position".
When the user pushes the switch operating member 14 in this state, the contact portion 48 comes into contact with the contact portion 62 and further moves the blocking member 16 in the G direction, as shown in FIG. As a result, the blocking member 16 reaches the permitted position, and as shown in FIG. 11, the switch operating member 14 can reach the on position.
It should be noted that if the blocking member 16 does not move from the permitted position, the contact portion 47 may come into contact with the contact portion 61 and the switch operating member 14 may not reach the on position. That is. By increasing the area of the portion where the abutting portion 47 and the abutting portion 61 abut, the distance that the blocking member 16 must move from the blocking position to the permitted position increases. Therefore, the distance that the blocking member 16 moves may be insufficient due to the operation of the locking operating member 15. Even in such a case, the contact portion 48 abuts on the contact portion 62 and further moves the blocking member 16 in the G direction, so that the blocking member 16 surely reaches the permitted position and the off-lock is released. It will be released.

図１２に示すように、スイッチ操作部材１４を最大限押し込んだ状態において、スイッチ操作部材１４の庇部４６は、ロック操作部材１５の鍔部５２よりもＡ側に位置する。スイッチ操作部材１４のこのときの位置を「オンロック解除位置」と呼ぶ。スイッチ操作部材１４がオンロック解除位置に位置するとき、ロック操作部材１５は、Ｅ方向に最大限押し込んで、オンロック位置に到達することができる。
ロック操作部材１５をオンロック位置まで押し込んだ状態において、使用者がスイッチ操作部材１４を押す力を緩めると、スイッチ操作部材１４は、付勢部材８４によってＢ方向に付勢され、図１３に示すように、Ｂ方向へ回動する。しかし、庇部４６のＢ方向にロック操作部材１５のボタン部５１が位置するので、スイッチ操作部材１４の回動が阻止され、スイッチ操作部材１４は、オン位置に保持され、オフ位置に到達できない。これにより、オン状態が維持される。
更に、この状態において、使用者がロック操作部材１５を押す力を緩めると、ロック操作部材１５は、付勢部材８５によってＦ方向に付勢され、Ｆ方向に移動する。しかし、鍔部５２のＦ方向に庇部４６が位置するので、ロック操作部材１５の移動が阻止され、ロック操作部材１５は、オンロック位置に保持され、解除位置に到達できない。これにより、オンロック状態が維持される。 As shown in FIG. 12, when the switch operating member 14 is pushed to the maximum, the eaves 46 of the switch operating member 14 is located on the A side of the flange portion 52 of the lock operating member 15. The position of the switch operating member 14 at this time is referred to as an "on-lock release position". When the switch operating member 14 is located at the on-lock release position, the lock operating member 15 can be pushed to the maximum in the E direction to reach the on-lock position.
When the user relaxes the force for pushing the switch operating member 14 while the lock operating member 15 is pushed to the on-lock position, the switch operating member 14 is urged in the B direction by the urging member 84, and is shown in FIG. As such, it rotates in the B direction. However, since the button portion 51 of the lock operating member 15 is located in the B direction of the eaves portion 46, the rotation of the switch operating member 14 is prevented, and the switch operating member 14 is held in the on position and cannot reach the off position. .. As a result, the on state is maintained.
Further, in this state, when the user relaxes the force for pushing the lock operation member 15, the lock operation member 15 is urged in the F direction by the urging member 85 and moves in the F direction. However, since the eaves portion 46 is located in the F direction of the collar portion 52, the movement of the lock operation member 15 is blocked, and the lock operation member 15 is held in the on-lock position and cannot reach the release position. As a result, the on-lock state is maintained.

オンロック状態を解除するには、スイッチ操作部材１４をもう一度押し込んで、図１２に示すように、オンロック解除位置に到達させる。庇部４６と鍔部５２との係合が解除される。ロック操作部材１５は、付勢部材８５によってＦ方向に付勢されているので、Ｆ方向に移動し、オンロック位置から離脱して、解除位置又はオフロック位置に到達する。この状態で、使用者がスイッチ操作部材１４を押す力を緩めると、スイッチ操作部材１４は、付勢部材８４によってＢ方向に付勢されているので、Ｂ方向に移動し、オン位置から離脱して、オフ位置に到達する。
留意すべき点は、スイッチ操作部材１４が、オフ状態にするときは、付勢部材８４の力によってスイッチ操作部材１４が戻る構造である点である。したがって、オンロック状態であるにもかかわらず使用者が無理にオフ状態にしようとしても、スイッチ操作部材１４に大きな力が加わることはない。したがって、オンロック機構は、オフロック機構と比べて強度が比較的弱い構造でよい。
トリガースイッチ１０において、オンロック及びオフロックは、一つのロック操作部材１５を操作することにより実現できる。しかし、オンロックとオフロックとでは、要求される強度が異なる。オフロック機構は、阻止部材１６などを用いて構成することにより、比較的強い強度が達成できる。 To release the on-lock state, the switch operating member 14 is pushed in again to reach the on-lock release position as shown in FIG. The engagement between the eaves portion 46 and the collar portion 52 is released. Since the lock operation member 15 is urged in the F direction by the urging member 85, the lock operation member 15 moves in the F direction, separates from the on-lock position, and reaches the release position or the off-lock position. In this state, when the user relaxes the force for pushing the switch operating member 14, the switch operating member 14 is urged in the B direction by the urging member 84, so that the switch operating member 14 moves in the B direction and is released from the on position. And reach the off position.
It should be noted that when the switch operating member 14 is turned off, the switch operating member 14 returns by the force of the urging member 84. Therefore, even if the user tries to forcibly turn it off even though it is in the on-lock state, a large force is not applied to the switch operating member 14. Therefore, the on-lock mechanism may have a structure having a relatively weak strength as compared with the off-lock mechanism.
In the trigger switch 10, on-lock and off-lock can be realized by operating one lock operation member 15. However, the required strength differs between on-lock and off-lock. A relatively strong strength can be achieved by forming the off-lock mechanism by using the blocking member 16 or the like.
