Description

本発明は、多方向操作が可能なスイッチ装置に関する。 The present invention relates to a switch device capable of multidirectional operation.

従来、ノブを多方向に操作可能なスイッチ装置が周知である（特許文献１等参照）。この種のスイッチ装置には、例えば、第１操作ノブと、第２操作ノブと、第１接点と、第２接点とを備えたものが存在する。 2. Description of the Related Art Conventionally, there is a well-known switch device in which a knob can be operated in multiple directions (see Patent Document 1, etc.). This type of switch device includes, for example, a switch device that includes a first operation knob, a second operation knob, a first contact, and a second contact.

第１操作ノブは、全体として環状に形成され、上下左右の４方向に対する操作を受け付けるように、揺動自在に支持されている。第２操作ノブは、第１操作ノブが有する開口に配置され、第１操作ノブとは異なる特定方向への押圧操作を受け付けるように構成されている。第１接点は、第１操作ノブに対する操作の有無を検出する。第２接点は、第２操作ノブに対する操作の有無を検出する。 The first operation knob is formed in an annular shape as a whole, and is supported so as to be swingable so as to receive operations in four directions of up, down, left, and right. The second operating knob is arranged in the opening of the first operating knob and configured to receive a pressing operation in a specific direction different from that of the first operating knob. The first contact detects whether or not the first operating knob is operated. The second contact detects whether or not the second operating knob is operated.

特開２００５－３０２３４７号公報JP 2005-302347 A

ところで、このようなスイッチ装置においては、第１操作ノブに対する操作に追従して第２操作ノブが揺動する。一方で、第２操作ノブに対する押圧操作を受け付けると、第１操作ノブに対する操作とは別に第２操作ノブが単独で変位する。第２操作ノブに対する操作の荷重が想定以上に大きいと、第２接点に加わる荷重は想定よりも大きなものとなる。 By the way, in such a switch device, the second operation knob swings following the operation of the first operation knob. On the other hand, when a pressing operation on the second operating knob is received, the second operating knob is independently displaced independently of the operation on the first operating knob. If the operating load on the second operating knob is larger than expected, the load applied to the second contact will be larger than expected.

すると、通常のスイッチ装置では、接点に異常をきたす可能性がある。すなわち、従来の技術では、より部品の耐久性に配慮したスイッチ装置が望まれていた。
本発明の目的は、部品の耐久性を確保可能にしたスイッチ装置を提供することにある。 Then, in a normal switch device, there is a possibility that an abnormality will occur in the contact. In other words, in the prior art, a switch device that takes into account the durability of the parts has been desired.

As shown in FIG. 7, when the upper portion of the first knob 4 is operated (operated in the direction of the arrow A1 in the figure) in the first operation section 2, the first knob 4 is rotated with the center P as a fulcrum. It swings in the arrow A2 direction in the figure. At this time, the back surface of the first knob 4 pushes the first pusher 38a downward in the plane of the drawing, deforming the first bulging portion 19 of the rubber 18, and pushes the first contact 16a from above to turn it on. As a result, an ON signal is output from the first contact 16a to the controller 55 as the contact signal S1, and the controller 55 detects that the upper portion of the first knob 4 has been operated.

ここで、例えば第２操作部３を第１操作部２に追従しない構造とした場合、第１操作部２及び第２操作部３を、ともにボディ部１２で支持する構造にする必要がある。この構造の場合、第１操作部２が操作された際、第１ノブ４が第２ノブ５に当たらないようにするために、第１ノブ４及び第２ノブ５の間に、ある程度の大きさの隙間を設ける必要があり、見映えが悪くなってしまう。 Here, for example, if the second operating section 3 is structured so as not to follow the first operating section 2 , it is necessary to adopt a structure in which both the first operating section 2 and the second operating section 3 are supported by the body section 12 . In the case of this structure, in order to prevent the first knob 4 from hitting the second knob 5 when the first operation part 2 is operated, there is a certain amount of space between the first knob 4 and the second knob 5. It is necessary to provide a small gap, and the appearance deteriorates.

一方、本例のスイッチ装置１の場合、第１操作部２が操作されたとき、第２操作部３が第１操作部２に追従するように動く構造をとっている。本例の場合、第１操作部２が操作された際、第１操作部２が第２操作部３を押し引きすることにより、第２操作部３が第１操作部２に追従する。この構造の場合、第２操作部３が第１操作部２の軸部分として機能するので、第１ノブ４が操作された場合には、第１ノブ４にかかる操作荷重を第２ノブ５で支持することになる。この構造にすれば、第１ノブ４及び第２ノブ５の間に隙間を設けない組み付け状態をとることが可能となるので、スイッチ装置１を見映えのよいものとすることが可能となる。 On the other hand, in the case of the switch device 1 of this example, when the first operating portion 2 is operated, the second operating portion 3 moves so as to follow the first operating portion 2 . In this example, when the first operating unit 2 is operated, the second operating unit 3 follows the first operating unit 2 by pushing and pulling the second operating unit 3 . In the case of this structure, the second operating portion 3 functions as a shaft portion of the first operating portion 2, so when the first knob 4 is operated, the operating load applied to the first knob 4 is transferred by the second knob 5. will support. With this structure, it is possible to achieve an assembled state in which no gap is provided between the first knob 4 and the second knob 5, so that the switch device 1 can be made attractive.

図８に示すように、第２操作部３が押圧操作（同図の矢印Ｂ１方向に操作）された場合、第２操作部３は、下方に直線移動する。第２操作部３の下方への操作は、第１操作部２との間の隙間Ｗ（図７参照）により許容されている。このとき、第２ノブ５の裏面の突起２４がラバー１８の第２膨出部２０を変形させながら第２接点１７を上から押してオンする。これにより、第２接点１７から制御部５５に接点信号Ｓ２としてオン信号が出力され、第２ノブ５が押圧操作されたことが制御部５５に検知される。 As shown in FIG. 8, when the second operating portion 3 is pressed (operated in the direction of arrow B1 in the figure), the second operating portion 3 linearly moves downward. A downward operation of the second operating portion 3 is allowed by a gap W (see FIG. 7) between the second operating portion 2 and the first operating portion 2 . At this time, the protrusion 24 on the back surface of the second knob 5 deforms the second swelling portion 20 of the rubber 18 and presses the second contact 17 from above to turn it on. As a result, an ON signal is output from the second contact 17 to the controller 55 as the contact signal S2, and the controller 55 detects that the second knob 5 has been pressed.

ところで、図９に示すように、第２操作部３を第１操作部２の操作に追従させる構造とした場合、例えば第１操作部２の第１ノブ４が経年変化等によって撓む（或いは撓る）と、その形状変形に影響を受けて、第１操作部２が初期状態のときよりも紙面下方向に位置が変化してしまう。このように、第１操作部２が撓んだ状態となった際、第２操作部３が押圧操作された場合には、第２操作部３が初期状態のときよりも深く移動し、第２接点１７やラバー１８を高荷重で押してしまうことになる。 By the way, as shown in FIG. 9, when the second operation part 3 is configured to follow the operation of the first operation part 2, for example, the first knob 4 of the first operation part 2 bends (or bending), the position of the first operation unit 2 changes downward in the plane of the drawing from that in the initial state due to the influence of the shape deformation. In this manner, when the first operating portion 2 is bent and the second operating portion 3 is pressed, the second operating portion 3 moves deeper than in the initial state, The two contacts 17 and the rubber 18 will be pushed with a high load.

しかし、本例の場合、ボディ部１２にストッパ部４７を設けて、第２操作部３の押込方向への過剰な移動を規制するようにした。このため、第２操作部３の過剰な下方への移動がストッパ部４７により制限される。よって、第１操作部２が撓んだ状態の際に第２操作部３が押圧操作されても、ストッパ部４７で第２操作部３の動きを止めて、第２接点１７に過荷重をかかり難くするので、部品劣化を生じ難くすることが可能となる。 However, in the case of this example, the body portion 12 is provided with the stopper portion 47 to restrict excessive movement of the second operating portion 3 in the pushing direction. Therefore, excessive downward movement of the second operating portion 3 is restricted by the stopper portion 47 . Therefore, even if the second operating portion 3 is pressed while the first operating portion 2 is bent, the movement of the second operating portion 3 is stopped by the stopper portion 47 and the second contact 17 is overloaded. Since it is made difficult to apply, it is possible to make it difficult to cause component deterioration.

上記実施形態のスイッチ装置１によれば、以下のような効果を得ることができる。
（１）スイッチ装置１には、押圧操作を受けた場合に押圧操作によって複数の方向（本例は４方向）に傾倒可能な第１操作部２と、第１操作部２への操作方向とは異なる方向である特定方向（本例は矢印Ｂ１方向）への押圧操作に従って変位する第２操作部３とを設けた。第２操作部３は、第１操作部２への押圧操作を受け付けた場合に、第１操作部２への操作に追従して変位する。また、スイッチ装置１には、第２操作部３に対する特定方向Ｂ１への押圧操作を検出する接点（本例は第２接点１７）と、第２操作部３の特定方向Ｂ１への変位を規制するストッパ部４７とを設けた。 According to the switch device 1 of the above embodiment, the following effects can be obtained.
(1) The switch device 1 includes a first operating portion 2 that can be tilted in a plurality of directions (four directions in this example) by a pressing operation when a pressing operation is received, and an operation direction to the first operating portion 2. and a second operating portion 3 that is displaced according to a pressing operation in a specific direction (the direction of arrow B1 in this example) that is different from the direction. The second operating portion 3 is displaced following the operation to the first operating portion 2 when the pressing operation to the first operating portion 2 is accepted. Further, the switch device 1 includes a contact (the second contact 17 in this example) for detecting a pressing operation on the second operating portion 3 in the specific direction B1, and a contact for regulating the displacement of the second operating portion 3 in the specific direction B1. A stopper portion 47 is provided.

この構成によれば、第１操作部２が例えば経年変化等によって撓んだ際、第１操作部２とともに第２操作部３が下方に沈み込むことがある。この状態において、第２操作部３が押圧操作された場合、第２操作部３の操作時の移動が途中でストッパ部４７によって規制されるので、ストッパ部４７に接触してからはそれ以上、押込方向に移動しない。このように、ストッパ部４７によって押込量が規制されるので、第２操作部３の第２接点１７に過荷重がかかり難くなる。よって、スイッチ装置１において部品劣化を抑制することができる。 According to this configuration, when the first operation portion 2 is bent due to aging, for example, the second operation portion 3 may sink downward together with the first operation portion 2 . In this state, when the second operating portion 3 is pressed, the stopper portion 47 restricts the movement of the second operating portion 3 during operation. Does not move in pushing direction. As described above, the pushing amount is regulated by the stopper portion 47 , so that the second contact 17 of the second operating portion 3 is less likely to be overloaded. Therefore, deterioration of parts in the switch device 1 can be suppressed.

（２）ストッパ部４７は、第１操作部２が操作されて第２操作部３が第１操作部２に追従する場合に、第２操作部３が接触しない突出量Ｔに設定されている。すなわち、ストッパ部４７は、第１操作部２が操作されて第２操作部３が第１操作部２に追従する場合に、第２操作部３が非接触となるように配置されている。よって、第１操作部２の操作時にストッパ部４７が第２操作部３に干渉しないので、スイッチ装置１にストッパ部４７を設けても、第１操作部２の操作に違和感を与えることがない。 (2) The stopper portion 47 is set to a projection amount T that does not make contact with the second operating portion 3 when the first operating portion 2 is operated and the second operating portion 3 follows the first operating portion 2. . That is, the stopper portion 47 is arranged so that the second operating portion 3 is out of contact when the first operating portion 2 is operated and the second operating portion 3 follows the first operating portion 2 . Therefore, since the stopper portion 47 does not interfere with the second operation portion 3 when the first operation portion 2 is operated, even if the switch device 1 is provided with the stopper portion 47, the operation of the first operation portion 2 does not feel uncomfortable. .

（３）ストッパ部４７は、第１操作部２及び第２操作部３の少なくとも一方を変位可能に支持するボディ部１２に形成されている。よって、ボディ部１２の一部を形状変更することにより、強固なストッパ部４７を容易に形成することができる。 (3) The stopper portion 47 is formed in the body portion 12 that supports at least one of the first operating portion 2 and the second operating portion 3 so as to be displaceable. Therefore, by changing the shape of a portion of the body portion 12, the strong stopper portion 47 can be easily formed.

（４）第２操作部３は、操作を受け付ける第２ノブ５と、その第２ノブ５に対する操作に従って第２接点１７を操作する第２ホルダ２３とを備える。ストッパ部４７は、第２ノブ５及び第２ホルダ２３の少なくとも一方による第２接点１７への操作を規制するように設けられている。よって、例えばストッパ部４７で第２ノブ５を位置規制する構造と、ストッパ部４７で第２ホルダ２３を位置規制する構造とのどちらも採用することが可能となるので、装置の設計自由度を確保することができる。 (4) The second operation portion 3 includes the second knob 5 that receives an operation, and the second holder 23 that operates the second contact 17 according to the operation of the second knob 5 . The stopper portion 47 is provided to restrict the operation of the second contact 17 by at least one of the second knob 5 and the second holder 23 . Therefore, for example, it is possible to employ both a structure for restricting the position of the second knob 5 by the stopper portion 47 and a structure for restricting the position of the second holder 23 by the stopper portion 47, thereby increasing the degree of freedom in designing the device. can be secured.

（５）スイッチ装置１は、第１操作部２及び第２操作部３の両方を照明する照明部５０を備える。よって、共通の照明部５０で第１操作部２及び第２操作部３の両方を照明することが可能となるので、部品点数を少なく抑えることができる。 (5) The switch device 1 includes an illumination section 50 that illuminates both the first operation section 2 and the second operation section 3 . Therefore, since it becomes possible to illuminate both the first operation section 2 and the second operation section 3 with the common illumination section 50, the number of parts can be reduced.
