Description

本発明は、電動工具用スライドスイッチに関するものである。   The present invention relates to a slide switch for an electric tool.

変速機構を内蔵する電動工具において、その変速状態の切り替え用としてスライドスイッチを用いたものがある。この用途のスライドスイッチにおける位置決め機構の一例を図２に示す。一対のレール２，２間に配したスライド部３には弾性を有するアーム部３２，３２を設けて、各アーム部３２，３２の各先端外面に夫々突起３１，３１を設けている。図中３３はその両端部のばね部３３ａ，３３ｂを上記アーム部３２，３２に接触させて各突起３１，３１をレール２側に付勢しているばねである。   Some electric tools incorporating a speed change mechanism use a slide switch for switching the speed change state. An example of a positioning mechanism in the slide switch for this application is shown in FIG. The slide portion 3 disposed between the pair of rails 2 and 2 is provided with elastic arm portions 32 and 32, and protrusions 31 and 31 are provided on the outer front surfaces of the arm portions 32 and 32, respectively. In the figure, reference numeral 33 denotes a spring in which the spring portions 33a and 33b at both ends thereof are brought into contact with the arm portions 32 and 32 to urge the protrusions 31 and 31 toward the rail 2 side.

そして、各レール２のスライド部３側の面には、レール２の長手方向（スライド部３のスライド方向）に沿って凸部２２と凹部２３とを交互に形成しており、スライド部３をスライドさせる時、突起３１はレール２の凹部２３から凸部２２を乗り越えて隣の凹部２３に移動する。突起３１が凹部２３内に位置することで位置決めされる。   And the convex part 22 and the recessed part 23 are alternately formed in the surface at the side of the slide part 3 of each rail 2 along the longitudinal direction (slide direction of the slide part 3) of the rail 2, and the slide part 3 is formed. When sliding, the protrusion 31 moves from the concave portion 23 of the rail 2 over the convex portion 22 to the adjacent concave portion 23. The protrusion 31 is positioned by being positioned in the recess 23.

ここにおいて、従来はレール２における各凹部２３の形状を同じ形状としていた。すなわち、図４に示すように、凹部２３は底面２６と、底面２６から凸部２２に向かう傾斜面２４，２５とを有しているが、複数設けられた各凹部２３は全て同じ形状となっていた。   Here, conventionally, the shape of each recess 23 in the rail 2 is the same. That is, as shown in FIG. 4, the recess 23 has a bottom surface 26 and inclined surfaces 24 and 25 from the bottom surface 26 toward the projection 22, but the plurality of recesses 23 are all in the same shape. It was.

この場合、凹部２３が３個以上並んで３段以上の切り替えができるものにおいては、スライド操作を加えた時のスライド部３の動きに不具合が生じることがあった。以下、具体的に説明する。   In this case, in the case where three or more recesses 23 are arranged and can be switched in three or more stages, there may be a problem in the movement of the slide part 3 when a slide operation is applied. This will be specifically described below.

凹部２３から隣り合う凹部２３に突起３１を移動させるには、凸部２２を乗り越えさせなくてはならず、この時、傾斜面２４，２５の傾斜角に応じた力が必要となる。今、図４(a)においてスライド部３を白抜き矢印方向にスライドさせる時、傾斜面２５のためにアーム部３２の弾性及びばね片３３ａの弾性に抗して突起３１を後退させる力が必要であり、このための力を加えなくてはならないが、えてして加える力が大きすぎる場合があり、この時には突起３１が隣の凹部２３で止まらずに、図４(b)に示すようにさらに次の凸部２２に乗りあげたり、さらに隣の凹部２３にまで移動してしまうことがあった。   In order to move the protrusion 31 from the recess 23 to the adjacent recess 23, the protrusion 22 must be moved over, and at this time, a force corresponding to the inclination angle of the inclined surfaces 24 and 25 is required. 4A, when the slide part 3 is slid in the direction of the white arrow, a force for retracting the protrusion 31 against the elasticity of the arm part 32 and the elasticity of the spring piece 33a is required for the inclined surface 25. However, there is a case where the force to be applied is too large. In this case, the protrusion 31 does not stop at the adjacent recess 23, and as shown in FIG. May have moved up to the convex portion 22 or moved to the adjacent concave portion 23.

本発明は上記問題に鑑みてなされたもので、その課題は、順序良く一段階ずつ切替えることができる電動工具用のスライドスイッチを提供することである。   This invention is made | formed in view of the said problem, The subject is providing the slide switch for electric tools which can be switched in order one step at a time.

A slide switch for an electric power tool having a positioning region that is urged toward the rail side to contact the positioning region, and the pair of rails each include the positioning region. The slide part has a pair of arm parts substantially parallel to the longitudinal direction of the rail, one arm part is provided with a projection in contact with the positioning area of one rail, and the other arm part is positioned for the other rail. has a protrusion in contact with the region, the positioning region has a plurality of protrusions projecting to the slide portion in the sliding direction, the plurality of protrusions same A concave portion is provided between the convex portion, a descending inclined surface falling from the convex portion toward the concave portion, and an upward inclined surface rising from the concave portion to the convex portion adjacent to the convex portion in the sliding direction. The positioning unit has at least three positioning units, and the inclination angle of the rising inclined surface constituting the positioning unit at least two units before the positioning unit at the final position in the sliding direction is adjacent to the sliding direction. It is characterized by being smaller than the inclination angle of the rising inclined surface of the matching positioning unit.

最終位置にある位置決め単位から２単位手前にある位置決め単位を構成する凹部から、最終位置にある位置決め単位から１単位手前にある位置決め単位を構成する凹部に突起を移動させることになるスライド操作は、他のスライド操作よりも小さい力で行えるようにしたものである。   The slide operation that moves the projection from the concave portion constituting the positioning unit two units before the positioning unit at the final position to the concave portion constituting the positioning unit one unit before from the positioning unit at the final position is It can be performed with less force than other slide operations.

本発明においては、スライド部を移動させるための力を少々加えすぎても、行き過ぎてしまうという事態を招くおそれが少なくて、順序良く一段ずつ切り替えることができる。   In the present invention, even if a little force is applied to move the slide portion, there is little risk of overshooting, and switching can be performed step by step in order.

図１から図３に基づいて本願発明の実施形態について説明する。本実施形態における電動工具用スライドスイッチ１は、一対のレール２，２と、前記レール２，２に挟まれてスライドするスライド部３とを備え、前記レール２は前記スライド部３をスライド方向に位置決めする位置決め領域を有し、前記スライド部３は前記レール２，２側に付勢されて前記位置決め領域と接する突起３１，３１を有しており、前記位置決め領域は、前記スライド部側に突出している凸部２２をスライド方向に複数有し、前記複数の凸部２２同士の間には凹部２３が設けられており、前記凸部２２から前記凹部２３に向かって降る降り傾斜面２４と、前記凹部２３から前記凸部とスライド方向に隣り合う凸部２２まで昇る昇り傾斜面２５，２７と、で１つの位置決め単位とし、この位置決め単位を少なくとも３単位有するものであり、スライド方向の最終位置にある位置決め単位から２単位以上手前にある位置決め単位を構成する前記昇り傾斜面２７の傾斜角度αが、スライド方向に隣り合う位置決め単位の前記昇り傾斜面２５の傾斜角度βよりも小さいものである。   An embodiment of the present invention will be described with reference to FIGS. The power tool slide switch 1 according to the present embodiment includes a pair of rails 2 and 2 and a slide portion 3 that slides between the rails 2 and 2, and the rail 2 moves the slide portion 3 in a sliding direction. The slide portion 3 has projections 31 and 31 that are urged toward the rails 2 and 2 and come into contact with the positioning region, and the positioning region protrudes toward the slide portion. A plurality of convex portions 22 in the sliding direction, a recess 23 is provided between the plurality of convex portions 22, and a descending inclined surface 24 falling from the convex portion 22 toward the concave portion 23, The rising inclined surfaces 25 and 27 rising from the concave portion 23 to the convex portion 22 adjacent to the convex portion in the sliding direction form one positioning unit, and the positioning unit has at least three units. The inclination angle α of the ascending inclined surface 27 that constitutes the positioning unit two or more units before the positioning unit at the final position in the sliding direction is the inclination of the ascending inclined surface 25 of the positioning unit adjacent in the sliding direction. It is smaller than the angle β.

図２にスライドスイッチ１の全体を示す。このスライドスイッチ１は、一対のレール２，２と、レール２，２に挟まれてスライドするスライド部３とを有する。   FIG. 2 shows the entire slide switch 1. The slide switch 1 includes a pair of rails 2 and 2 and a slide portion 3 that slides between the rails 2 and 2.

各レール２，２は、スライド部３の動きをガイドして一方向に往復移動させるとともに、スライド部３のスライドに関して位置決めを行うもので、両レール２，２は図示していない部材（たとえば電動工具のハウジング）によって相互に連結されている。   The rails 2 and 2 guide the movement of the slide part 3 to reciprocate in one direction, and perform positioning with respect to the slide of the slide part 3. Are interconnected by a tool housing).

平行並列に配された両レール２，２は、互いに対向する方向に突出する４つの凸部２２，２２，２２，２２を上記スライド部３のスライド方向に連続するように形成されている。そして、各レール２の隣合う凸部２２，２２間には夫々凹部２３が形成されている。このために図示例では総計３個の凹部２３，２３，２３がある。   Both rails 2, 2 arranged in parallel and parallel are formed such that four projecting portions 22, 22, 22, 22 projecting in directions facing each other are continuous in the sliding direction of the slide portion 3. And the recessed part 23 is formed between the adjacent convex parts 22 and 22 of each rail 2, respectively. For this purpose, there are a total of three recesses 23, 23, 23 in the illustrated example.

スライド部３は、そのスライド方向（レール２の長手方向）に略並行する一対のアーム部３２ａ，３２ｂを有しており、各アーム部３２ａ，３２ｂの先端で且つレール２と対向する外面には夫々突起３１が設けられている。この突起３１が上記レール２の凹部２３に嵌ることでスライド部３のスライド方向における位置決めがなされる。図中３３はばねであり、両端部のばね片３３ａ，３３ｂを夫々アーム部２１ａ，２１ｂに接触して各アーム部２１ａ，２１ｂをレール２，２側に夫々付勢する。このために上記突起３１はアーム部３１ａ，３１ｂの弾性とばね３３の弾性による付勢を受けた状態で凹部２３に嵌り込む。   The slide portion 3 has a pair of arm portions 32a and 32b substantially parallel to the slide direction (longitudinal direction of the rail 2), and on the outer surface facing the rail 2 at the tips of the arm portions 32a and 32b. A protrusion 31 is provided for each. The projection 31 is fitted in the recess 23 of the rail 2 so that the slide portion 3 is positioned in the slide direction. In the figure, reference numeral 33 denotes a spring, and the spring pieces 33a and 33b at both ends are brought into contact with the arm portions 21a and 21b, respectively, and the arm portions 21a and 21b are urged toward the rails 2 and 2, respectively. For this purpose, the protrusion 31 is fitted into the recess 23 in a state in which it is biased by the elasticity of the arm portions 31 a and 31 b and the elasticity of the spring 33.

各レール２に夫々設けられた複数の凹部２３は、夫々傾斜面となっている側壁で凸部２２につながっているが、スライド部３をスライドさせる方向において、凸部２２から前記凹部２３の底面２６に向かって降る降り傾斜面２４と、凹部２３の底面２６から前記凸部２２とスライド方向に隣り合う凸部２２まで昇る昇り傾斜面２７，２５とで１つの位置決め単位を構成すると考えた場合、図示例のものでは３つの位置決め単位を備えたものとなる。   The plurality of recesses 23 provided in each rail 2 are connected to the projections 22 by inclined side walls, respectively, but in the direction in which the slide unit 3 is slid, the bottoms of the recesses 23 from the projections 22. When it is considered that one descending inclined surface 24 falling toward 26 and rising inclined surfaces 27 and 25 rising from the bottom surface 26 of the concave portion 23 to the convex portion 22 adjacent to the convex portion 22 in the sliding direction constitute one positioning unit. In the illustrated example, three positioning units are provided.

そしてここではスライド方向の最終位置にある位置決め単位から２単位以上手前にある位置決め単位を構成する昇り傾斜面２７の傾斜角度αを、スライド方向に隣り合う位置決め単位の昇り傾斜面２５の傾斜角度βよりも小さくしている。   In this case, the inclination angle α of the ascending inclined surface 27 constituting the positioning unit two or more units before the positioning unit at the final position in the sliding direction is set as the inclination angle β of the ascending inclined surface 25 of the positioning unit adjacent in the sliding direction. Smaller than that.

言い換えるならば、レール２の長手方向両端に位置して片側にのみ他の凹部２３が存在している凹部２３は、凸部２２を介して他の凹部２３が隣接する側の傾斜面２７と、他方の傾斜面２５とでその傾斜角が異なっており、両隣に他の凹部２３が存在している凹部２３、すなわち中央に位置している凹部２３は、その両側壁の傾斜面２４，２５が同じ傾斜角度となっている。そしてこれら傾斜面２４，２５，２７のうち、中央の凹部２３に夫々凸部２２を介してつながっている傾斜面２７の傾斜角度αを、他の傾斜面２４，２５の傾斜角度βより小さくしている。図中２６は上述のように凹部２３における底面を示しているが、凹部２３はこの底面２６がないものであってもよい。   In other words, the recess 23, which is located at both ends in the longitudinal direction of the rail 2 and has the other recess 23 only on one side, has an inclined surface 27 on the side where the other recess 23 is adjacent via the projection 22, The other inclined surface 25 has an inclined angle different from that of the other inclined surface 25, and the recessed portion 23 in which the other recessed portion 23 exists on both sides, that is, the recessed portion 23 located in the center has inclined surfaces 24, 25 on both side walls. It has the same inclination angle. Of these inclined surfaces 24, 25, and 27, the inclination angle α of the inclined surface 27 that is connected to the central concave portion 23 via the convex portion 22 is made smaller than the inclination angle β of the other inclined surfaces 24 and 25. ing. In the drawing, reference numeral 26 denotes the bottom surface of the recess 23 as described above, but the recess 23 may not have the bottom surface 26.

今、図１(a)に示すように、レール２の端部にある凹部２３に突起３１が嵌り込んでいる状態から、スライド部３を図中白抜き矢印で示す方向にスライドさせることで、突起３１を中央の凹部２３にまで移動させる場合、突起３１は傾斜角度αが緩い傾斜面２７に沿って移動し、この時、前記ばね付勢に抗して後退し、凸部２２を乗り越えた後、中央の凹部２３に嵌り込む。この時に必要な力は、傾斜角度αを３０°、傾斜角度βを４５°とすると、傾斜角度βである傾斜面２４，２５に沿って移動させる場合に比して、約７０％程度の力でよい。   Now, as shown in FIG. 1 (a), from the state in which the projection 31 is fitted in the recess 23 at the end of the rail 2, the slide part 3 is slid in the direction indicated by the white arrow in the figure. When the projection 31 is moved to the central concave portion 23, the projection 31 moves along the inclined surface 27 having a gentle inclination angle α, and at this time, the projection 31 moves backward against the spring bias and gets over the convex portion 22. Then, it is fitted into the central recess 23. The force required at this time is about 70% of the force when the inclination angle α is 30 ° and the inclination angle β is 45 °, compared to the case where the inclination angle β is moved along the inclined surfaces 24 and 25. It's okay.

このために、傾斜面２７に沿って移動させる際の力が少々強くても、突起３１が傾斜面２７から凸部２２を乗り越えて隣の凹部２３に嵌り込んだ後、更に傾斜面２５（あるいは傾斜面２４）に沿って移動して更に次の凸部２２に乗り上げるようなことはなく、中央の凹部２３において位置決め保持される。   For this reason, even if the force at the time of moving along the inclined surface 27 is a little strong, after the protrusion 31 gets over the convex portion 22 from the inclined surface 27 and fits into the adjacent concave portion 23, the inclined surface 25 (or further) It moves along the inclined surface 24) and does not ride on the next convex portion 22, and is positioned and held in the central concave portion 23.

中央に位置する凹部２３に嵌り込んでいる突起３１を、レール２の長手方向両端に位置する凹部２３に移動させる場合は、傾斜面２４，２５の傾斜角度βが大であるが、スライド部３そのもののスライドストロークが別に規制されているために、両端の凹部２３に突起３１が嵌り込んだ状態で保持される。   When the protrusion 31 fitted in the recess 23 located at the center is moved to the recesses 23 positioned at both ends in the longitudinal direction of the rail 2, the inclination angle β of the inclined surfaces 24 and 25 is large, but the slide portion 3 Since the slide stroke is regulated separately, the protrusion 31 is held in the recessed portions 23 at both ends.

レール２の両端に位置する凹部２３は、他の凹部２３が隣接していない側の側壁を傾斜面ではなく直角壁としているものであってもよい。   The concave portions 23 positioned at both ends of the rail 2 may be configured such that the side walls on the side where the other concave portions 23 are not adjacent are not inclined surfaces but are right-angle walls.

図３は上記スライドスイッチ１を備えた電動工具を示しており、電動工具の上面部分に配されたスライドスイッチ１は、電動工具における減速比の切り替えについての切り替えスイッチとして用いられている。   FIG. 3 shows an electric tool provided with the slide switch 1, and the slide switch 1 arranged on the upper surface portion of the electric tool is used as a changeover switch for changing a reduction ratio in the electric tool.
