Description

【０００１】
【発明の属する技術分野】
本発明はスイッチ装置に関し、より詳しくはロータリーノブの中心孔にプッシュノブを進退可能に組み付けてロータリースイッチととプッシュスイッチの両機能を備えたスイッチ装置に関する。
【０００２】
【従来の技術】
一般に、この種のスイッチ装置では、スイッチボディに形成したノブ取付孔にロータリーノブを回転可能に組付け、ロータリーノブに形成した中心孔にプッシュノブを進退可能に嵌合している。
【０００３】
【発明が解決しようとする課題】
従来のスイッチ装置では、ロータリーノブの中心とノブ取付孔の中心がずれて見栄えが悪くなることがある。
また、ロータリーノブの中心孔にプッシュノブを嵌合しているので、ロータリーノブを回したとき、プッシュノブが動いたり、プッシュノブを押したときロータリーノブが動いてしまうことがある。
一方、ロータリーノブとプッシュノブが互いに連動しないようにロータリーノブの中心孔とプッシュノブとの間に遊びを設けると、プッシュノブの位置ずれが生じて、見栄えが悪くなる。
本発明はかかる点に鑑み、ロータリーノブとプッシュノブ間の連動を防止するとともにロータリーノブとプッシュノブの位置ずれを防止できるスイッチ装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
請求項１に記載の発明は、スイッチボディに形成したノブ取付孔にロータリーノブを回転可能に組み付けるとともに、ロータリーノブに形成した中心孔にプッシュノブを進退可能に組み付けたスイッチ装置であって、
円筒形の第１ガイド部材とこの第１ガイド部材の内側に同心状に形成した円筒形の第２ガイド部材を有するノブホルダーを前記スイッチボディに固定し、
前記ロータリーノブを前記第１ガイド部材に回転可能に嵌合することにより前記ノブ取付孔に所要の遊びをもってかつ同心状に組み付け、
前記プッシュノブを前記第２ガイド部材に進退可能に嵌合することにより前記ロータリーノブの中心孔に所要の遊びをもって、かつ同心状に組み付けたことを特徴とする。
【０００５】
【発明の作用・効果】
本発明によれば、ロータリーノブを第１ガイド部に嵌合させ、プッシュノブを第２ガイド部に嵌合し、両ガイド部を有するノブホルダーをスイッチボディに固定したので、ロータリーノブとノブ取付孔の間及びロータリーノブの中心孔とプッシュノブの間に遊びを設けてもロータリーノブ及びプッシュノブの位置ずれが生じない。
また、ロータリーノブの中心孔とプッシュノブの間に遊びを設けることによりロータリーノブの回転操作が円滑になるとともにロータリーノブとプッシュノブの連動を防止できる。
【０００６】
【発明の実施の形態】
以下に本発明を図面に基づき説明するに、図１には本発明の一実施形態に係るスイッチ装置が示されている。当該スイッチ装置１０はスイッチボディ１１、スイッチボディ１１の前面に形成したノブ取付孔１２に組付けたロータリーノブ１３、ロータリーノブ１３の前面に形成した中心孔１４に組付けたプッシュノブ１５、スイッチボディ１１の裏蓋を兼用するプリント配線基板１６及びノブホルダー１７を備えている。
スイッチボディ１１には位置決め用の突起１８が成形されている。一方、ノブホルダー１７に位置決め孔１９が形成されている。ノブホルダー１７は位置決め用突起１８を位置決め孔１９に嵌合することで、スイッチボディ１１のノブ取付孔１２に対して位置決めされ、ビス２０でスイッチボディ１１に固定されている。
【０００７】
ノブホルダー１７には円筒形の第１ガイド部２１と、この内側に円筒形の第２ガイド部２２が成形されている。ロータリーノブ１３は第１ガイド部２１に回転可能に嵌合させることで、ノブ取付孔１２に所要の遊びをもって、かつ同心状に組付けられている。また、ロータリーノブ１３の内端にはフランジ部２３が形成され、該フランジ部２３をノブ取付孔１２の内端部に係合させてロータリーノブ１３をノブ取付孔１２から抜け止めし、ノブホルダー１７に設けたリブ２４でフランジ部２３を内側から支持している。
ノブホルダー１７には凹部２５が形成され、凹部２５にコンタクトホルダー２６が摺動可能に格納されている。コンタクトホルダー２６はロータリーノブ１３と一体に回動するように同ノブ１３の内端に連結されている。コンタクトホルダー２６に保持された可動接点２７はプリント配線基板１６に固着した固定接点に摺接している。
【０００８】
プッシュノブ１５は裏面側に外側筒部２８と内側筒部２９を有し、外側筒部２８をノブホルダー１７の第２ガイド部２２に進退可能に嵌合させることで、ロータリーノブ１３の中心孔１４に所要の遊びをもって、かつ同心状に組付けられ、内側筒部２９の後端がプリント配線基板１６に固着したスイッチ３０に当接している。内側筒部２９にスリット３１が形成され、ノブホルダー１７に設けた係合片３２が係合してプッシュノブ１５が中心孔１４から抜け止めされている。
【０００９】
本実施形態に係るスイッチ装置１０の構造は以上の通りであって、ロータリーノブ１３を第１ガイド部２１に嵌合させ、プッシュノブ１５を第２ガイド部２２に嵌合し、両ガイド部２１，２２を有するノブホルダー１７を位置決め用突起１８と位置決め孔１９でノブ取付孔１２に対して位置決めしてスイッチボディ１１に固定したので、位置ずれすることなくロータリーノブ１３をノブ取付孔１２に同心状に配設でき、かつプッシュノブ１５をロータリーノブ１３の中心孔１４に同心状に配設できる。
また、ノブ取付孔１２とロータリーノブ１３の間及び中心孔１４とプッシュノブ１５の間に所要の遊びをもたせることができるので、ロータリーノブ１３の回転操作が円滑になるとともに、ロータリーノブ１３とプッシュノブ１５との連動を防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a switch device, and more particularly to a switch device having a function of both a rotary switch and a push switch by assembling a push knob in a central hole of the rotary knob so as to be able to advance and retract.
[0002]
[Prior art]
Generally, in this type of switch device, a rotary knob is rotatably assembled in a knob mounting hole formed in a switch body, and a push knob is fitted in a central hole formed in the rotary knob so as to be able to advance and retreat.
[0003]
[Problems to be solved by the invention]
In the conventional switch device, the center of the rotary knob and the center of the knob mounting hole may be misaligned and the appearance may deteriorate.
In addition, since the push knob is fitted in the center hole of the rotary knob, the push knob may move when the rotary knob is turned, or the rotary knob may move when the push knob is pressed.
On the other hand, if play is provided between the center hole of the rotary knob and the push knob so that the rotary knob and the push knob do not interlock with each other, the position of the push knob is shifted and the appearance is deteriorated.
In view of the above, an object of the present invention is to provide a switch device that can prevent interlocking between a rotary knob and a push knob and can prevent displacement of the rotary knob and the push knob.
[0004]
[Means for Solving the Problems]
The invention according to claim 1 is a switch device in which a rotary knob is rotatably assembled to a knob mounting hole formed in a switch body, and a push knob is assembled to a center hole formed in the rotary knob so as to be able to advance and retract.
A knob holder having a cylindrical first guide member and a cylindrical second guide member formed concentrically inside the first guide member is fixed to the switch body,
By assembling the rotary knob with the first guide member so as to be rotatable, the knob mounting hole is assembled concentrically with required play,
By fitting the push knob to the second guide member so as to be able to advance and retract, the push knob is assembled concentrically with a required play in the center hole of the rotary knob .
[0005]
[Operation and effect of the invention]
According to the present invention, the rotary knob is fitted to the first guide portion, the push knob is fitted to the second guide portion, and the knob holder having both guide portions is fixed to the switch body. Even if play is provided between the holes and between the center hole of the rotary knob and the push knob, the rotary knob and the push knob are not displaced.
Further, by providing play between the center hole of the rotary knob and the push knob, the rotary knob can be smoothly rotated and the interlocking of the rotary knob and the push knob can be prevented.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings. FIG. 1 shows a switch device according to an embodiment of the present invention. The switch device 10 includes a switch body 11, a rotary knob 13 assembled in a knob mounting hole 12 formed on the front surface of the switch body 11, a push knob 15 assembled in a center hole 14 formed on the front surface of the rotary knob 13, a switch body. 11 includes a printed wiring board 16 that also serves as a back cover and a knob holder 17.
A projection 18 for positioning is formed on the switch body 11. On the other hand, a positioning hole 19 is formed in the knob holder 17. The knob holder 17 is positioned with respect to the knob mounting hole 12 of the switch body 11 by fitting the positioning protrusion 18 into the positioning hole 19, and is fixed to the switch body 11 with a screw 20.
[0007]
A cylindrical first guide portion 21 and a cylindrical second guide portion 22 are formed inside the knob holder 17. The rotary knob 13 is rotatably fitted to the first guide portion 21 so as to be assembled concentrically in the knob mounting hole 12 with a required play. A flange portion 23 is formed at the inner end of the rotary knob 13, and the flange portion 23 is engaged with the inner end portion of the knob mounting hole 12 to prevent the rotary knob 13 from coming off from the knob mounting hole 12. The flange portion 23 is supported from the inside by the ribs 24 provided on the inner surface 17.
A recess 25 is formed in the knob holder 17, and a contact holder 26 is slidably stored in the recess 25. The contact holder 26 is connected to the inner end of the knob 13 so as to rotate integrally with the rotary knob 13. The movable contact 27 held by the contact holder 26 is in sliding contact with a fixed contact fixed to the printed circuit board 16.
[0008]
The push knob 15 has an outer cylindrical portion 28 and an inner cylindrical portion 29 on the back surface side, and the outer cylindrical portion 28 is fitted to the second guide portion 22 of the knob holder 17 so as to be able to advance and retract. 14 has a necessary play and is concentrically assembled, and the rear end of the inner cylindrical portion 29 is in contact with the switch 30 fixed to the printed wiring board 16. A slit 31 is formed in the inner cylindrical portion 29, and an engagement piece 32 provided on the knob holder 17 is engaged to prevent the push knob 15 from being detached from the center hole 14.
[0009]
The structure of the switch device 10 according to the present embodiment is as described above. The rotary knob 13 is fitted to the first guide portion 21, the push knob 15 is fitted to the second guide portion 22, and both guide portions 21 are fitted. , 22 is positioned with respect to the knob mounting hole 12 by the positioning projection 18 and the positioning hole 19 and fixed to the switch body 11, so that the rotary knob 13 is concentric with the knob mounting hole 12 without being displaced. The push knob 15 can be arranged concentrically in the center hole 14 of the rotary knob 13.
Further, since the required play can be provided between the knob mounting hole 12 and the rotary knob 13 and between the center hole 14 and the push knob 15, the rotary operation of the rotary knob 13 becomes smooth and the rotary knob 13 and the push knob 15 are pushed. Interlocking with the knob 15 can be prevented.
