Description

【0001】
【発明の属する技術分野】
本発明はトリガとプッシュレバーとの操作順序を変えることによって単発、連発打ちに切り換えることができる打込機に関するものである。
【0002】
【従来の技術】
従来の打込機の一例に、特開平7−237148号公報に記載されたトリガとプッシュレバーとの操作順序を変えることによって単発、連発打ちに切り換えることができる打込機がある。これは、トリガの引き操作を行った後でプッシュレバーの操作を行うと連発打ちとなり、プッシュレバーの操作を行った後でトリガの引き操作を行うと単発打ちとなる構造をし、単発打ちの際にはトリガバルブを作動状態でロックするというものであった。
【0003】
【発明が解決しようとする課題】
上記した特開平7−237148号公報に開示された打込機は、単発打ちの際にはトリガバルブを作動状態でロックするというものであるため、単発打ちとした場合には打込み終了後に打撃機構が打込み状態にある。
このため、トリガの操作を解除すると同時にトリガバルブが初期状態に復帰して打撃機構も初期状態に復帰し、打撃機構の復帰行程である圧縮空気の排気が行われる。打込み終了後には本体を移動させ打込み状況を確認すること等があるが、この際にトリガの操作を解除すると、不意に打撃機構が初期状態に復帰し圧縮空気の排気が行われるという欠点があった。
本発明の目的は、上記欠点を解消し、単発打ちの場合であってもプッシュレバーの押し上げ操作の解除によりトリガバルブが初期状態へ復帰する打込機を提供することである。
【0004】
【課題を解決するための手段】
上記目的は、単発打ち終了後にプッシュレバーの押し上げ操作のみを解除すると、プッシュレバーの押し上げ操作にアームプレートが干渉しなくなるようにすることにより達成される。
【0005】
【発明の実施の形態】
本発明打込機の一実施形態を図1〜図7を用いて以下説明する。
図において、1は止具を打撃する図示しない打撃機構を起動させるトリガバルブ、2は上昇することによりトリガバルブ1を動作させるプランジャ、3は回動可能に設けられ、外部より操作可能なトリガ、4は上下動可能に設けられたプッシュレバー、5はピン6によりトリガ3に回動可能に取付けられたトリガアーム、7はトリガアーム5内に摺動可能に設けられ、スプリング8により常時プッシュレバー4側に付勢されているアームプレート、7aはアームプレート7上面に設けられた凸部、7bはアームプレート7のプッシュレバー4側への摺動を規制するアームプレート端部である。
【0006】
図1に示すようにトリガ3の引き操作及びプッシュレバー4の押し上げ操作が行われていない状態では、プランジャ2は下降位置にありトリガバルブ1は打込み待機状態にある。この際には、アームプレート7はスプリング8によりアームプレート端部7bがピン6に突き当たるまでプッシュレバー4側に摺動した状態にあり、トリガアーム5はアームプレート7がプッシュレバー4上端に突き当たるまで下側に回動した状態にある。
【0007】
次に、トリガ3の引き操作を行った後でプッシュレバー4の押し上げ操作を行いトリガバルブ1を動作させる連発打ちを図2、図3を用いて説明する。
図2に示すようにトリガ3の引き操作が行われると、ピン6が上昇するためトリガアーム5及びアームプレート7がプランジャ2に近づくが、プランジャ2は押し上げられずトリガバルブ1は動作しない。この後に、図3に示すようにプッシュレバー4の押し上げ操作を行うと、アームプレート7がプッシュレバー4上端により押し上げられ、トリガアーム5がピン6を支点として上方に回動するので、プランジャ2がアームプレート7により押し上げられてトリガバルブ1が動作し、打込みが行われる。打込み終了後にプッシュレバー4の押し上げ操作が解除されると、図2に示す状態に復帰し、再びプッシュレバー4の押し上げ操作が行われたならば図3に示す状態となりトリガバルブ1が動作し打込みが行われる。
なお、トリガ3の引き操作が行われた際にはアームプレート7上面に設けられた凸部7aは、図2に示すようにプランジャ2とプッシュレバー4との間に位置する。
【0008】
次に、プッシュレバー4の押し上げ操作を行った後でトリガ3の引き操作を行いトリガバルブ1を動作させる単発打ちを図4〜図7を用いて説明する。
図4に示すようにプッシュレバー4の押し上げ操作を行うと、アームプレート7がプッシュレバー4上端により押し上げられるが、プランジャ2は下降位置にありトリガバルブ1は動作しない。この後、トリガ3の引き操作が行われると、図5に示すようにトリガアーム5が上昇してアームプレート7がプランジャ2を押し上げ、トリガバルブ1が動作し打込みが行われる。なお、図4に示すようにプッシュレバー4の押し上げ操作が行われた際には、トリガ3の引き操作が行われていないためにピン6が下降位置にあるので、アームプレート7上面に設けられた凸部7aはプランジャ2よりトリガ3側に位置する。
【0009】
図4に示すようにプッシュレバー4の押し上げ操作が行われた後で、トリガ3の引き操作を行うと図5に示すようにアームプレート7がプランジャ2を押し上げ、トリガバルブ1が動作し打込みが行われる。なお、トリガ3の引き操作途中にアームプレート7上面に設けられた凸部7aのプッシュレバー4側の面がプランジャ2下端部のトリガ3側の面に突き当たり、トリガ3が更に引かれる毎にアームプレート7はスプリング8の付勢力に抗してトリガアーム5内を摺動しトリガ3が完全に引かれると図5に示す状態となる。打込み終了後には、スプリング8の付勢力により凸部7aのプッシュレバー4側の面がプランジャ2下端部のトリガ3側の面に突き当たった状態を保ち、アームプレート7はトリガ3側に摺動した状態を保つ。
【0010】
トリガ3の引き操作によりトリガバルブ1が動作し打込みが行われた後に、プッシュレバー4の押し上げ操作が解除されると、プッシュレバー4の下降と共にプランジャ2が下降してトリガバルブ1が初期状態に復帰し、図示しない打撃機構が初期状態に復帰する。プランジャ2が下降するとトリガアーム5及びアームプレート7がプランジャ2が下降した分下方に回動するが、この際にもアームプレート7の凸部7aとプランジャ2下端部とはスプリング8の働きにより突き当たった状態を保ちアームプレート7はトリガ3側に摺動した状態を保つ。
この状態で、再度プッシュレバー4の押し上げ操作が行われたとしても図7に示すようにプッシュレバー4上端とアームプレート7とは当接しなくなる。このため、単発打ちを行った後で誤ってプッシュレバー4の押し上げ操作が行われたとしても打込みが行われることがない。なお、3aはトリガアーム5底部と突き当たるトリガ3に設けられた突当面であり、プッシュレバー4の押し上げ操作が解除されプランジャ2が下降した際に、トリガアーム5が下方に回動してアームプレート7の凸部7aとプランジャ2下端部との係合が解除されてしまうのを防止するために設けられたものある。
【0011】
単発打ちを行いプッシュレバー4の押し上げ操作が解除された図6の状態から、トリガ3の引き操作を解除すると、アームプレート7の凸部7aとプランジャ2下端部との係合が解除されアームプレート7はスプリング8によりプッシュレバー4側に摺動し、図1に示す初期状態となる。
【0012】
上記したように、単発打ち終了後にプッシュレバー4の押し上げ操作を解除すると、プッシュレバー4上端とアームプレート7とが当接することがなくなるようにしたので、プッシュレバー4の押し上げ操作の解除によりトリガバルブ1が初期状態に復帰するようになる。このように、単発打ちの場合であってもプッシュレバー4の押し上げ操作の解除によりトリガバルブ1が初期状態に復帰するので、打込み終了後に本体を被打込材から離すと同時に打撃機構が初期状態に復帰し、復帰行程である圧縮空気の排気が行われるようになる。
【0013】
図8に本発明打込機の他の実施形態を示す。
本実施形態の打込機は、図に示すようにアームプレート7にトリガ3に設けられたピン6を内部に位置させる長孔7cを設けた構成をしている。このような構成とすることにより上記実施形態と同様の効果を得ることができ、かつトリガアーム5を設ける必要がなくなるので、トリガアーム5内にゴミ等が混入してしまいアームプレート7が適当な動作を行わなくなるという問題を解消することができると共に組立性の向上を図ることができるようになる。
なお、上記実施形態ではアームプレート7に単発打ち終了後にプッシュレバー4の押し上げ操作を解除するとプランジャ2と係合する凸部7aを設けた構成としたが、図9に示すようにアームプレート7に単発打ち操作時にプランジャ2と係合する穴7dを設けた構成としても良く上記実施形態と同様の作用効果を奏し得ることができる。
【0014】
上記実施形態ではアームプレート7に凸部7aあるいは穴7dを設け、単発打ち終了後にプッシュレバー4の押し上げ操作を解除すると、凸部7aあるいは穴7dとプランジャ2下端部とが係合する構成としたが、本発明打込機はこれに限るものではなく、単発打ち終了後にプッシュレバー4の押し上げ操作が解除されるとアームプレート7がトリガ3側に摺動した状態を保ち、再度プッシュレバー4の押し上げ操作が行われたとしてもプッシュレバー4がアームプレート7を押し上げることができない構成であれば良い。また、アームプレート7の凸部7aあるいは穴7dと係合する部材をプランジャ2近傍に設けた構成としても良い。
【0015】
【発明の効果】
本発明によれば、単発打ち終了後にプッシュレバーの押し上げ操作を解除すると、プッシュレバーにアームプレートが干渉しなくなるようにしたので、単発打ちの場合であってもプッシュレバーの押し上げ操作の解除によりトリガバルブが初期状態に復帰する打込機を提供することができるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a driving machine that can be switched between single shot and continuous shot by changing the operation order of a trigger and a push lever.
[0002]
[Prior art]
As an example of a conventional driving machine, there is a driving machine described in JP-A-7-237148, which can be switched between single shot and continuous shot by changing the operation order of a trigger and a push lever. This is a structure in which if the push lever is operated after performing the trigger pulling operation, it will be fired continuously, and if the trigger pulling operation is performed after operating the push lever, it will be constructed in a single shot. In some cases, the trigger valve was locked in the activated state.
[0003]
[Problems to be solved by the invention]
The driving machine disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 7-237148 locks the trigger valve in an activated state at the time of single shot. Is in the driving state.
For this reason, simultaneously with the release of the trigger operation, the trigger valve returns to the initial state, the striking mechanism also returns to the initial state, and the compressed air, which is the return stroke of the striking mechanism, is exhausted. After the driving is completed, the main body may be moved to check the driving status.However, if the trigger operation is canceled at this time, the striking mechanism will unexpectedly return to the initial state and the compressed air will be exhausted. It was.
An object of the present invention is to provide a driving machine in which the trigger valve is returned to the initial state by releasing the push-up operation of the push lever even in the case of single-shot driving, eliminating the above-mentioned drawbacks.
[0004]
[Means for Solving the Problems]
The above object is achieved by preventing the arm plate from interfering with the push-up operation of the push lever when only the push-up operation of the push lever is canceled after the single shot is finished.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention driving machine will be described below with reference to FIGS.
In the figure, 1 is a trigger valve that activates a striking mechanism (not shown) that strikes a stopper, 2 is a plunger that operates the trigger valve 1 when it is raised, 3 is a trigger that is rotatably provided and can be operated from the outside, 4 is a push lever provided so as to be movable up and down, 5 is a trigger arm that is rotatably attached to the trigger 3 by a pin 6, and 7 is slidably provided in the trigger arm 5, and is always pushed by a spring 8. The arm plate urged toward the side 4, 7 a is a convex portion provided on the upper surface of the arm plate 7, and 7 b is an end of the arm plate that regulates the sliding of the arm plate 7 toward the push lever 4.
[0006]
As shown in FIG. 1, in a state where the pulling operation of the trigger 3 and the push-up operation of the push lever 4 are not performed, the plunger 2 is in the lowered position and the trigger valve 1 is in the driving standby state. At this time, the arm plate 7 is in a state of sliding toward the push lever 4 until the arm plate end portion 7 b hits the pin 6 by the spring 8, and the trigger arm 5 is until the arm plate 7 hits the upper end of the push lever 4. It is in a state of rotating downward.
[0007]
Next, the repeated stroke in which the trigger valve 1 is operated by pushing the push lever 4 after the trigger 3 is pulled will be described with reference to FIGS.
When pulling operation of the trigger 3 is performed as shown in FIG. 2, although the trigger arm 5 and the arm plate 7 the pin 6 rises approaches the plunger 2, flop plunger 2 is the trigger valve 1 not pushed up does not operate. Thereafter, when the push lever 4 is pushed up as shown in FIG. 3, the arm plate 7 is pushed up by the upper end of the push lever 4, and the trigger arm 5 rotates upward with the pin 6 as a fulcrum. The trigger valve 1 is pushed up by the arm plate 7 and driven. When the push-up operation of the push lever 4 is released after the completion of driving, the state returns to the state shown in FIG. 2, and if the push-up operation of the push lever 4 is performed again, the state shown in FIG. Is done.
When the trigger 3 is pulled, the convex portion 7a provided on the upper surface of the arm plate 7 is positioned between the plunger 2 and the push lever 4 as shown in FIG.
[0008]
Next, a single shot for operating the trigger valve 1 by pulling the trigger 3 after the push-up operation of the push lever 4 will be described with reference to FIGS.
As shown in FIG. 4, when the push lever 4 is pushed up, the arm plate 7 is pushed up by the upper end of the push lever 4, but the plunger 2 is in the lowered position and the trigger valve 1 does not operate. Thereafter, when the trigger 3 is pulled, the trigger arm 5 rises as shown in FIG. 5, the arm plate 7 pushes up the plunger 2, the trigger valve 1 operates, and driving is performed. As shown in FIG. 4, when the push lever 4 is pushed up, the trigger 6 is not pulled, so the pin 6 is in the lowered position, so that it is provided on the upper surface of the arm plate 7. The convex portion 7 a is located closer to the trigger 3 than the plunger 2.
[0009]
When the trigger 3 is pulled after the push lever 4 is pushed up as shown in FIG. 4, the arm plate 7 pushes up the plunger 2 as shown in FIG. Done. During the pulling operation of the trigger 3, the surface on the push lever 4 side of the convex portion 7a provided on the upper surface of the arm plate 7 abuts the surface on the trigger 3 side of the lower end of the plunger 2, and the arm is moved each time the trigger 3 is further pulled. When the plate 7 slides within the trigger arm 5 against the biasing force of the spring 8 and the trigger 3 is completely pulled, the state shown in FIG. After the driving is finished, the push lever 4 side surface of the convex portion 7a is kept in contact with the trigger 3 side surface of the lower end of the plunger 2 by the urging force of the spring 8, and the arm plate 7 slides to the trigger 3 side. Keep state.
[0010]
After the trigger valve 1 is operated and driven by the pulling operation of the trigger 3, when the push-up operation of the push lever 4 is released, the plunger 2 is lowered as the push lever 4 is lowered and the trigger valve 1 is returned to the initial state. The hitting mechanism (not shown) returns to the initial state. When the plunger 2 is lowered, the trigger arm 5 and the arm plate 7 are rotated downward by the amount that the plunger 2 is lowered. At this time, the convex portion 7a of the arm plate 7 and the lower end portion of the plunger 2 are abutted by the action of the spring 8. The arm plate 7 is kept slid to the trigger 3 side.
In this state, even if the push lever 4 is pushed up again, the upper end of the push lever 4 and the arm plate 7 do not contact each other as shown in FIG. For this reason, even if a push-up operation of the push lever 4 is mistakenly performed after performing a single shot, the driving is not performed. Reference numeral 3a denotes an abutting surface provided on the trigger 3 that abuts against the bottom of the trigger arm 5, and when the push-up operation of the push lever 4 is released and the plunger 2 is lowered, the trigger arm 5 is rotated downward and the arm plate 7 is provided in order to prevent the engagement between the convex portion 7a and the lower end of the plunger 2 from being released.
[0011]
When the pulling operation of the trigger 3 is released from the state shown in FIG. 6 where the push-up operation of the push lever 4 is released by performing a single shot, the engagement between the convex portion 7a of the arm plate 7 and the lower end portion of the plunger 2 is released. 7 is slid to the push lever 4 side by the spring 8 to be in the initial state shown in FIG.
[0012]
As described above, when the push-up operation of the push lever 4 is canceled after the single shot is finished, the upper end of the push lever 4 and the arm plate 7 are not brought into contact with each other. 1 will return to the initial state. Thus, even in the case of a single shot, the trigger valve 1 returns to the initial state by releasing the push-up operation of the push lever 4, so that the impact mechanism is in the initial state at the same time as the main body is separated from the material to be driven after the driving is finished. Then, the compressed air that is the return stroke is exhausted.
[0013]
It shows another embodiment of the present invention driving machine in FIG.
Fastening tool of the present embodiment has a configuration in which a long hole 7c for positioning pins 6 provided on the trigger 3 to the arm plate 7 as shown in FIG therein. Since With such a structure, it is possible to obtain the same effect as the above embodiment, and it is not necessary to provide a trigger arm 5, is suitable arm plate 7 dust ends up contaminating the trigger arm 5 The problem that the operation is not performed can be solved and the assembling property can be improved.
In the above-described embodiment , the arm plate 7 is provided with the convex portion 7a that engages with the plunger 2 when the push-up operation of the push lever 4 is released after the single shot is finished. However, as shown in FIG. it can be well can achieve the same effect as the above embodiment as a configuration in which the plunger 2 and the engagement holes 7d during single-handed operation.
[0014]
The convex portion 7a or the hole 7d provided in the arm plate 7 in the above embodiment, when releasing the push operation of the push lever 4 after single strike ends, the convex portion 7a or the hole 7d and the plunger 2 lower part has a configuration to engage However, the driving machine of the present invention is not limited to this, and when the push-up operation of the push lever 4 is released after the single shot is finished, the arm plate 7 keeps sliding to the trigger 3 side, and the push lever 4 is moved again. Even if the push-up operation is performed, the push lever 4 may be configured so that the arm plate 7 cannot be pushed up. Moreover, it is good also as a structure which provided the member engaged with the convex part 7a or the hole 7d of the arm plate 7 in the plunger 2 vicinity.
[0015]
【The invention's effect】
According to the present invention, when the push lever push-up operation is canceled after the single shot is finished, the arm plate does not interfere with the push lever. A driving machine in which the valve returns to the initial state can be provided.
