Description

本発明はダブルノック機構に関するものである。   The present invention relates to a double knock mechanism.

従来からプッシュロックスイッチ等に使用されている操作部を一回押すと押し込んだ状態を保持し、もう一回操作部を押し込むと元の状態に戻るオルタネイト動作を得るための機構の一つにダブルノック機構がある。その中で特許文献１は操作部が操作前と操作後において、不本意に動いてしまうのを防止する構造になっている。ここで操作前とは操作部を押し込んでいない状態であり、操作後とは操作部を押し込み回転子が移動してスイッチを切り替え終えた状態のことであり、操作時とは操作前から操作後に移行している状態である。(特許文献１参照)   It is doubled as one of the mechanisms to obtain the alternate operation that keeps the pushed-in state when it is pressed once and has been pushed once again, and returns to the original state when pushed again. There is a knock mechanism. Among them, Patent Document 1 has a structure that prevents the operation unit from moving unintentionally before and after the operation. Here, before operation is a state where the operation unit is not pushed in, after operation is a state where the operation unit is pushed in and the rotor has moved and the switch has been switched, and during operation is from before operation to after operation. It is in a transitional state. (See Patent Document 1)

特許文献１のダブルノック機構の構成を示したのが図７である。支持部に係合する接触子にスイッチの切り替えと回転力を与える端面カムを備える。また支持部に係合し押し込むことで往復運動する円柱状の操作部曲面に、係合する接触子に回転力を与える第一歯形状カムと、係合する接触子が解離するのを係止する第二歯形状カムとを向かい合わせて形成される円筒溝カムを備える。またリング状の回転子外周面に端面カムと係わり合う接触子と、内周面に円筒溝カムと係わり合う接触子を備える。また押し込まれた回転子を押し戻す圧力を加える弾性体を備える。さらにリング状の回転子に円筒溝カム部分を貫通させて操作部を連結させる。また回転子の接触子が、支持部の端面カムと操作部の第一歯形状カムに同時に咬合できないように構成する。回転子は端面カムと第一歯形状カムに交互に咬合して回転力を得て端面カムを移動しスイッチを切り替える。   FIG. 7 shows the configuration of the double knock mechanism of Patent Document 1. An end face cam is provided for switching the switch and applying a rotational force to the contact engaging with the support portion. In addition, a cylindrical operation part curved surface that reciprocates by engaging with and pushing into the support part, and a first tooth-shaped cam that applies a rotational force to the engaging contact, and the engaging contact being disengaged are locked. A cylindrical groove cam formed to face the second tooth-shaped cam. The ring-shaped rotor has a contact that engages with the end face cam on the outer peripheral surface and a contact that engages with the cylindrical groove cam on the inner peripheral surface. Moreover, the elastic body which applies the pressure which pushes back the rotor which was pushed in is provided. Further, the cylindrical groove cam portion is passed through the ring-shaped rotor to connect the operation portion. Further, the contact of the rotor is configured so as not to be engaged with the end face cam of the support portion and the first tooth-shaped cam of the operation portion at the same time. The rotor alternately engages with the end face cam and the first tooth-shaped cam to obtain a rotational force, moves the end face cam, and switches the switch.

これにより操作後に支持部の端面カムに回転子が固定され、その回転子の内側の接触子を円筒溝カムが両側から挟み込んで連結している操作部も不本意に移動してしまうことを防止する。   As a result, the rotor is fixed to the end face cam of the support portion after the operation, and the operation portion where the cylindrical groove cam sandwiches and connects the contact inside the rotor from both sides is prevented from moving unintentionally. To do.

特許第４６７６５６２号Japanese Patent No. 4676562

しかしこの方法には、操作部をプラスチックなどの樹脂で成形する際に問題があった。それは図８で示したとおり、二つの歯形状カムを向かい合わせて構成される円筒溝カム部分にアンダーカットができてしまい、操作部を作る金型が複雑になってしまった。   However, this method has a problem when the operation part is formed of a resin such as plastic. As shown in FIG. 8, the cylindrical groove cam portion constituted by two tooth-shaped cams facing each other has an undercut, which complicates the mold for forming the operation portion.

そこで本発明の目的は、操作部が不本意に動かない構造のダブルノック機構の操作部や回転子をプラスチック成形する際に、アンダーカット部分が発生しない部品構成にすることである。   Accordingly, an object of the present invention is to provide a component configuration in which an undercut portion does not occur when the operation portion and the rotor of a double knock mechanism having a structure in which the operation portion does not move unintentionally are molded.

請求項１の発明は支持部に端面カムと、支持部に係合する操作部に第一歯形状カムと第二歯形状カムとを向かい合わせて形成される円筒溝カムと、リング状の回転子外周面に端面カムと係合する第一接触子と、回転子内周面に円筒溝カムと係合する第二接触子と、回転子に圧力を加える弾性体とを備え、回転子に円筒溝カム部分を貫通させて連結するダブルノック機構において、
係合する接触子に回転力を与える箇所のみ有する第一歯形状カムと、係合する第二接触子に接触して操作部が解離するのを係止する箇所のみ有する第二歯形状カムと、回転子一端の端面に第一歯形状カムと係合して回転力を得る第三接触子とを備え、前記円筒溝カムに代わり第一歯形状カムと第二歯形状カムを互い違いに向かい合わせて配置して形成される円筒溝カムを操作部に備えることを特徴とするダブルノック機構。
である。なおこれ以後の説明は操作部を上から下へ押す縦置き状態とする。 The invention according to claim 1 is a cylindrical groove cam formed by facing the end face cam in the support portion, the first tooth shape cam and the second tooth shape cam facing the operation portion engaged with the support portion, and a ring-shaped rotation The rotor includes a first contact that engages with the end face cam on the outer peripheral surface, a second contact that engages with the cylindrical groove cam on the inner peripheral surface of the rotor, and an elastic body that applies pressure to the rotor. In the double knock mechanism that connects through the cylindrical groove cam part,
A first tooth-shaped cam having only a portion for applying a rotational force to the engaging contact; and a second tooth-shaped cam having only a portion for contacting the second contact to be engaged and locking the disengagement of the operating portion. And a third contact that engages with the first tooth-shaped cam on one end face of the rotor to obtain a rotational force, and alternately turns the first tooth-shaped cam and the second tooth-shaped cam in place of the cylindrical groove cam. A double knock mechanism comprising a cylindrical groove cam formed by being arranged and formed in an operation portion.
It is. In the following description, it is assumed that the operation unit is vertically placed by pushing from the top to the bottom.

これにより円筒溝カムを構成する第一歯形状カムと第二歯形状カムの歯が一つ一つ独立した突起になる。一つ一つの突起になった第一歯形状カムと第二歯形状カムは円柱状の操作部の縦軸において互い違いにずらして配置する。よって上下から金型を組み合わせてプラスチック成形する際に、アンダーカット部分が発生しない。しかしこのままでは第一歯形状カムが連なるのではなく一つ一つ独立した突起となったことで間隔が空き、その空いた間隔に第二接触子がはまってしまい、第一接触子が端面カムを摺動して回転するのを阻害してしまう。そのためリング状の回転子一端の端面に連なって配置された第三接触子が常に第一歯形状カムと接することで、回転子が空いた間隔にはまってしまうのを防止し回転力を得ることを特徴とする。   Thereby, the teeth of the first tooth-shaped cam and the second tooth-shaped cam constituting the cylindrical groove cam become independent protrusions one by one. The first tooth-shaped cam and the second tooth-shaped cam that are formed as individual protrusions are staggered in the vertical axis of the cylindrical operation portion. Therefore, an undercut portion does not occur when plastic molding is performed by combining dies from above and below. However, in this state, the first tooth-shaped cams are not connected, but the protrusions become independent one by one, so that there is an interval, and the second contact is caught in the space, and the first contact becomes the end face cam. It will interfere with sliding and rotating. Therefore, the third contact arranged continuously with the end face of one end of the ring-shaped rotor is always in contact with the first tooth-shaped cam, so that the rotor is prevented from getting stuck in the space and the rotational force is obtained. It is characterized by.

本発明により操作部が不本意に移動してしまうのを防ぐダブルノック機構において、操作部の二種類の歯形状を互い違いにすることでプラスチック成形時にアンダーカットを生じさせないため、金型の製造及び、メンテナンス費用を下げることができる。   In the double knock mechanism that prevents the operation unit from moving unintentionally according to the present invention, the two types of tooth shapes of the operation unit are alternated so that no undercut occurs during plastic molding. , Can reduce the maintenance cost.

図１は請求項１の操作部をロックするダブルノック機構の実施方法を分解斜視図で示した図である。内部円筒曲面に端面カム６を備える支持部１と、円筒溝カム２０を備える操作部２と、外側円筒曲面に第一接触子３０及び内側円筒曲面に第二接触子３１を備える回転子３と、回転子３に常に圧力を加えるコイルスプリング等の弾性体４と、弾性体４を支え支持部１一端に蓋をする支持部底面５とを備える。また図１においては支持部１と支持部底面５を結合するために、支持部結合用溝１１と支持部底面結合用突起５１とを組み合わせて結合させるが、接着剤等を使い結合させてもよい。   FIG. 1 is an exploded perspective view showing a method of implementing a double knock mechanism for locking an operation portion of claim 1. A support portion 1 having an end cam 6 on an inner cylindrical curved surface, an operation portion 2 having a cylindrical groove cam 20, a rotor 3 having a first contact 30 on an outer cylindrical curved surface and a second contact 31 on an inner cylindrical curved surface, An elastic body 4 such as a coil spring that constantly applies pressure to the rotor 3 and a support portion bottom surface 5 that supports the elastic body 4 and covers the end of the support portion 1 are provided. Further, in FIG. 1, in order to couple the support part 1 and the support part bottom face 5, the support part coupling groove 11 and the support part bottom face coupling protrusion 51 are joined in combination. Good.

図２は支持部１の端面カム６を展開図で示した図である。支持部１の内部を円筒状にして、その円筒曲面に図２で示した端面カム６を備える。端面カム６は深溝６１と浅溝６２を交互に繰り返すことで構成する。回転子３の第一接触子３０が端面カム６の歯形状カムのカム山を一つ越えるごとに支持部１に対して上下に往復移動してスイッチとしての機能を得る。また支持部１、もしくは端面カム６には操作部２が支持部１に対して垂直に往復運動のみできるように、垂直移動用カム６３を備える。   FIG. 2 is a developed view of the end face cam 6 of the support portion 1. The inside of the support portion 1 is cylindrical, and the end cam 6 shown in FIG. 2 is provided on the cylindrical curved surface. The end face cam 6 is constituted by repeating the deep groove 61 and the shallow groove 62 alternately. Each time the first contact 30 of the rotor 3 exceeds the cam crest of the tooth-shaped cam of the end face cam 6, the first contact 30 moves up and down with respect to the support portion 1 to obtain a function as a switch. Further, the support portion 1 or the end face cam 6 is provided with a vertical movement cam 63 so that the operation portion 2 can only reciprocate vertically with respect to the support portion 1.

図３は操作部２の実施方法を（A）は正面図で、（B）は斜視図で示した図である。軸を円柱状にして第一歯形状カム２１、及び第二歯形状カム２２から成る円筒溝カム２０と、垂直移動用接触子２３を備える。第一歯形状カム２１は回転子３に回転力を与えるためにあるので、回転子３の進行方向側に歯形状の斜面を設置する。回転子３の進行方向と逆側の歯形状の斜面は、回転子３に一定方向へ回転力を与えるためには必要ないので設けない。また第二歯形状カム２２は操作後に、操作部２が回転子３から解離してしまうのを防ぐためにあるので、操作後の状態において係合する接触子と接している箇所に設置（第一歯形状カム２１、第二歯形状カム２２共に詳しくは図６参照）する。すると操作部２の縦軸において第一歯形状カム２１と第二歯形状カム２２の必要箇所が互い違いになり、金型製造時にアンダーカットがない操作部を製造できる。   3A and 3B are diagrams illustrating the operation method of the operation unit 2, in which FIG. 3A is a front view and FIG. A cylindrical groove cam 20 including a first tooth-shaped cam 21 and a second tooth-shaped cam 22 having a columnar shaft and a vertical movement contact 23 are provided. Since the first tooth-shaped cam 21 is for applying a rotational force to the rotor 3, a tooth-shaped slope is installed on the traveling direction side of the rotor 3. A tooth-shaped slope opposite to the traveling direction of the rotor 3 is not provided because it is not necessary for applying a rotational force to the rotor 3 in a certain direction. Further, since the second tooth-shaped cam 22 is provided to prevent the operating portion 2 from being detached from the rotor 3 after the operation, the second tooth-shaped cam 22 is installed at a location in contact with the engaging contact in the state after the operation (first (See FIG. 6 for details of both the tooth-shaped cam 21 and the second tooth-shaped cam 22). As a result, the necessary portions of the first tooth-shaped cam 21 and the second tooth-shaped cam 22 are staggered on the vertical axis of the operation unit 2, and an operation unit without an undercut can be manufactured at the time of mold manufacture.

また操作部２は支持部１に対して垂直に往復運動のみ可能であって軸心に対して回転してはならないので、支持部１の垂直移動用カム６３に係合する接触子が必要である。そのため図４で示したように一部の第一歯形状カム２１を操作部２の軸から延長し、延長させた箇所を垂直移動用接触子２３として利用する。ただし垂直移動用接触子２３は操作部２が支持部１に対して垂直移動のみできるようにするために存在するので、第一歯形状カム２１の一部を接触子にしなくてもよい。なお支持部１の垂直移動用カム６３と操作部２の垂直移動用接触子２３を組み合わせた際に、端面カム６と第一歯形状カム２１の山部分のピッチをずらして組み合わせることで、両方のカムと同時に噛み合うことができない回転子３は端面カム６と第一歯形状カム２１に交互に噛み合い回転力を得る。
Further, since the operation portion 2 can only reciprocate vertically with respect to the support portion 1 and should not rotate with respect to the axis, a contact that engages with the vertical movement cam 63 of the support portion 1 is required. is there. Therefore, as shown in FIG. 4, a part of the first tooth-shaped cams 21 is extended from the axis of the operation unit 2, and the extended part is used as the vertical movement contactor 23. However, since the vertical movement contact 23 exists so that the operation unit 2 can only move vertically with respect to the support unit 1, a part of the first tooth-shaped cam 21 does not have to be a contact. In addition, when the vertical movement cam 63 of the support portion 1 and the vertical movement contact 23 of the operation portion 2 are combined, both are combined by shifting the pitches of the crest portions of the end face cam 6 and the first tooth-shaped cam 21. The rotor 3 which cannot be meshed simultaneously with the other cams meshes alternately with the end face cam 6 and the first tooth-shaped cam 21 to obtain a rotational force.

図５は回転子３の実施方法を（Ａ）は正面図、（Ｂ）は平面図、（Ｃ）は断面図で示した図である。リング状にした回転子３の外側の曲面に端面カム６と係合する第一接触子３０を備える。また内側の曲面に第二歯形状カム２２と係合する第二接触子３１を備える。ここで操作部２の第一歯形状カム２１は歯形状の歯が連なっておらず一つ一つが個々に配置されているため、第二接触子３１では回転途中で第一歯形状カム２１の隙間にはまってしまう。すると第一接触子３０が端面カム６を摺動して回転することを阻害してしまう。そこでリング状の回転子３一端の端面に第一歯形状カム２１の隙間にはまらずに回転できるように、連なった形状の第三接触子３２を備える。   5A is a front view, FIG. 5B is a plan view, and FIG. 5C is a cross-sectional view. A first contact 30 that engages with the end cam 6 is provided on the outer curved surface of the ring-shaped rotor 3. A second contact 31 that engages with the second tooth-shaped cam 22 is provided on the inner curved surface. Here, since the first tooth-shaped cams 21 of the operation unit 2 are not connected with tooth-shaped teeth and are arranged one by one, the second contactor 31 rotates the first tooth-shaped cam 21 during the rotation. Get stuck in the gap. As a result, the first contact 30 is prevented from sliding and rotating on the end face cam 6. Accordingly, a third contact 32 having a continuous shape is provided on the end face of one end of the ring-shaped rotor 3 so that the ring-shaped rotor 3 can rotate without being caught in the gap of the first tooth-shaped cam 21.

図６は操作部２と回転子３を連結したときの係わり方の実施方法を（Ａ）は正面図、（Ｂ）は一部を展開図で示した図である。回転子３の回転の仕組みとして、端面カム６と円筒溝カム２０の二種類のカムと回転子３の接地面には上からは操作部２の押し込みにより、下からは弾性体４の圧力が働く。このとき操作部２からの押し込みの力が勝ると回転子３は下側へ押し込まれ円筒溝カム２０と噛み合う。その後弾性体４からの圧力が勝ると今度は回転子３が上側へ押し戻され端面カム６と噛み合う。よって以上の動作を行うことで回転子３は操作部２の押し込みと弾性体４から得る上下へのエネルギーを横回転のエネルギーに変換する。さらに操作部２は回転子３と連結されているので、回転子３が支持部１の端面カム６を構成する深溝６１と浅溝６２の間を行き来して上下の高低差を保持する際に操作部２も上下の高低差を保持する。   6A and 6B are diagrams showing an engaging method when the operation unit 2 and the rotor 3 are connected, in which FIG. 6A is a front view and FIG. As a mechanism of the rotation of the rotor 3, two types of cams, that is, the end face cam 6 and the cylindrical groove cam 20 and the grounding surface of the rotor 3 are pushed by the operation unit 2 from above and the pressure of the elastic body 4 from below. work. At this time, when the pushing force from the operation unit 2 is won, the rotor 3 is pushed downward and meshes with the cylindrical groove cam 20. Thereafter, when the pressure from the elastic body 4 wins, the rotor 3 is pushed back upward and meshed with the end face cam 6. Therefore, by performing the above operation, the rotor 3 converts the push-up of the operation unit 2 and the vertical energy obtained from the elastic body 4 into energy of lateral rotation. Furthermore, since the operation part 2 is connected with the rotor 3, when the rotor 3 moves back and forth between the deep groove 61 and the shallow groove 62 that constitute the end face cam 6 of the support part 1, the vertical difference is maintained. The operation unit 2 also maintains a vertical difference.

図６（Ａ１）は操作前であり、操作部２を押し込む前で回転子３の第一接触子３０が端面カム６の深溝６１の位置にあり、いわゆるスイッチオフの状態である。回転子３は弾性体４の圧力により第一接触子３０が支持部１の端面カム６の深溝６１へ押し付けられることで上下動ならびに回転移動を停止した状態である。また第一歯形状カム２１と第三接触子３２、及び第二歯形状カム２１と第二接触子３１の歯形状の噛み合わせは図６（Ｂ１）のようになる。支持部１に対して上下動のみできる操作部２は、円筒溝カム２０の第一歯形状カム２１が回転子３の第三接触子３２と接触し、第二歯形状カム２２が回転子３の第二接触子３１と接触している。よって操作部２は上下動できず、回転子３と同様に支持部１に対して固定した状態となる。   FIG. 6A1 shows a state before the operation, in which the first contact 30 of the rotor 3 is in the position of the deep groove 61 of the end face cam 6 before the operation unit 2 is pushed in, which is a so-called switch-off state. The rotor 3 is in a state in which the first contact 30 is pressed against the deep groove 61 of the end face cam 6 of the support portion 1 by the pressure of the elastic body 4 to stop vertical movement and rotational movement. Further, the meshing of the tooth shapes of the first tooth-shaped cam 21 and the third contact 32 and the second tooth-shaped cam 21 and the second contact 31 is as shown in FIG. 6 (B1). In the operation unit 2 that can only move up and down with respect to the support unit 1, the first tooth-shaped cam 21 of the cylindrical groove cam 20 contacts the third contact 32 of the rotor 3, and the second tooth-shaped cam 22 is the rotor 3. In contact with the second contact 31. Therefore, the operation unit 2 cannot move up and down and is fixed to the support unit 1 in the same manner as the rotor 3.

図６（Ａ２）は操作時であり、図６（Ａ１）から操作部２を底まで押し込んで回転子３が回転した状態である。回転子３は支持部１の端面カム６の影響が無くなり回転力が開放され回転することで、第三接触子３２が第一歯形状カム２１と噛み合っている。また円筒溝カム６と第二接触子３１、及び第三接触子３２のそれぞれの歯形状の噛み合わせは図６（Ｂ２）のようになる。このとき第一歯形状カム２１と第三接触子３２がお互いに圧力を掛け合っているため第二接触子３１は第二歯形状カム２２との接点を設ける必要がない。よって第二歯形状カム２２はこの状態の部分に配置しない。なお操作部２を回転子３に貫通させて連結するときは、第二歯形状カム２２と第二接触子３１が干渉しないこの状態で行うとよい。   FIG. 6 (A2) is during operation, and the rotor 3 is rotated by pushing the operating portion 2 to the bottom from FIG. 6 (A1). The rotor 3 is free from the influence of the end face cam 6 of the support portion 1 and the rotational force is released to rotate, so that the third contact 32 meshes with the first tooth-shaped cam 21. The meshing of the tooth shapes of the cylindrical groove cam 6, the second contact 31, and the third contact 32 is as shown in FIG. 6 (B2). At this time, since the first tooth-shaped cam 21 and the third contact 32 apply pressure to each other, the second contact 31 need not provide a contact point with the second tooth-shaped cam 22. Therefore, the 2nd tooth-shaped cam 22 is not arrange | positioned in the part of this state. In addition, when connecting the operation part 2 to the rotor 3, it is good to carry out in this state in which the second tooth-shaped cam 22 and the second contact 31 do not interfere.

図６（Ａ３）は操作時であり、図６（Ａ２）から操作部２への押し込みを解除することで回転子３がロック位置である端面カム６の浅溝６２へ移行する状態である。弾性体４の圧力により回転子３が操作部２を上へ押し戻しつつ、支持部１の端面カム６に沿って摺動して回転子３を浅溝６２にロックする途中である。また円筒溝カム２０と第二接触子３１、及び第三接触子３２のそれぞれの歯形状の噛み合わせは図６（Ｂ３）のようになる。   FIG. 6 (A3) is the time of operation, and is a state in which the rotor 3 moves to the shallow groove 62 of the end face cam 6 which is the locked position by releasing the pushing into the operation unit 2 from FIG. 6 (A2). While the rotor 3 pushes back the operating portion 2 upward by the pressure of the elastic body 4, the rotor 3 slides along the end face cam 6 of the support portion 1 to lock the rotor 3 to the shallow groove 62. Further, the meshing of the respective tooth shapes of the cylindrical groove cam 20, the second contact 31, and the third contact 32 is as shown in FIG. 6 (B3).

図６（Ａ４）は操作後であり、図６（Ａ３）から回転子３、及び操作部２をロックした状態である。回転子４が操作部２に対し回転移動し第二接触子３１、及び第三接触子３２は円筒溝カム２０内を摺動し第１接触子３０は支持部１の端面カム６へ押し付けられ回転子３がロックされる。また円筒溝カム２０と第二接触子３１、及び第三接触子３２のそれぞれの歯形状の噛み合わせは図６（Ｂ４）のようになる。このとき上下動のみできる操作部２は、円筒溝カム２０の第一歯形状カム２１と第二歯形状カム２２が第二接触子３１と第三接触子３２を挟み込んでブレの原因となる隙間を打ち消しあうように接しているため上下動できない。よって回転子３と同様に操作部２も固定した状態となる。以上が操作前から操作時を経て操作後に移行する円筒溝カム２０と第二接触子３１、及び第三接触子３２の関係である。また操作後から操作前の状態に移行する際の円筒溝カム２０と第二接触子３１、及び第三接触子３２の関係も同様の動きである。   FIG. 6 (A4) is after the operation, and is a state in which the rotor 3 and the operation unit 2 are locked from FIG. 6 (A3). The rotor 4 rotates and moves with respect to the operation portion 2, the second contact 31 and the third contact 32 slide in the cylindrical groove cam 20, and the first contact 30 is pressed against the end face cam 6 of the support portion 1. The rotor 3 is locked. Further, the meshing of the tooth shapes of the cylindrical groove cam 20, the second contact 31, and the third contact 32 is as shown in FIG. 6 (B4). At this time, the operation unit 2 that can only move up and down is a gap in which the first tooth-shaped cam 21 and the second tooth-shaped cam 22 of the cylindrical groove cam 20 sandwich the second contact 31 and the third contact 32 and cause blurring. Cannot move up and down because they are in contact with each other. Therefore, similarly to the rotor 3, the operation unit 2 is also fixed. The above is the relationship between the cylindrical groove cam 20, the second contact 31, and the third contact 32 that shifts from before operation to after operation. The relationship between the cylindrical groove cam 20, the second contact 31, and the third contact 32 when the operation is changed to the state before the operation is similar.
