本発明は双方向スイッチに関するものである。 The present invention relates to a bidirectional switch.

特開２００５−２８４０９２号公報JP 2005-284092 A

従来から、車両のフロントパネルや各種機器に双方向スイッチ（シーソースイッチとも呼ばれる）が使用されている。これは一対のスイッチ素子と、そのスイッチ素子の間に設けられた揺動支点部によって揺動自在にされた揺動スイッチノブとを備えたもので、揺動スイッチノブのいずれか一方の端部が押圧操作されると、対応するスイッチ素子が押圧付勢される構造になっている。また、押圧操作に伴って弾性変形する弾性部材が設けられ、押圧操作が解除された場合に、この弾性部材の弾性復帰力によって揺動スイッチノブが中立位置へ復帰する。 Conventionally, bidirectional switches (also referred to as seesaw switches) have been used for vehicle front panels and various devices. This includes a pair of switch elements and a swing switch knob that is swingable by a swing fulcrum provided between the switch elements. One end of the swing switch knob When the button is pressed, the corresponding switch element is pressed and biased. Further, an elastic member that is elastically deformed in accordance with the pressing operation is provided, and when the pressing operation is released, the swing switch knob is returned to the neutral position by the elastic return force of the elastic member.

しかし従来の双方向スイッチは押圧操作を解除すると、弾性部材によってスイッチノブが中立位置に復帰する際に、非押圧付勢側の端部が反動によってスイッチ素子に当接し、いわゆるタタキ音が発生することがあった。このタタキ音により高級感が損なわれたり、ユーザに不快感を与えたりする問題があった。 However, when the conventional bidirectional switch is released from the pressing operation, when the switch knob is returned to the neutral position by the elastic member, the end portion on the non-pressing biasing side comes into contact with the switching element due to the reaction, and a so-called tatting noise is generated. There was a thing. There is a problem in that the high-quality feeling is impaired by this tapping sound and the user feels uncomfortable.

この問題を解決するために従来は、タタキ音が発生する部分にグリースやラバー等の緩衝材を配置していた。しかしこの方法は、製造工程数が増加したり、グリースがスイッチ素子に悪影響を与える等の問題があった。 Conventionally, in order to solve this problem, a cushioning material such as grease or rubber has been arranged in a portion where a rattling sound is generated. However, this method has problems such as an increase in the number of manufacturing steps and a grease adversely affecting the switch element.

本発明の課題は、押圧操作を解除した際に、スイッチノブの非押圧付勢側の端部がスイッチ素子に当接して生じる音を、緩衝材を用いることなく効果的に低減できる双方向スイッチを提供することにある。 An object of the present invention is to provide a bidirectional switch that can effectively reduce the sound generated when the end of the non-pressing biasing side of the switch knob comes into contact with the switch element when the pressing operation is released, without using a cushioning material. Is to provide.

上記発明によると、揺動スイッチノブのノブ本体部と一体に揺動変位可能な摩擦受け部が形成され、その摩擦受け部の被摩擦面に当接する摩擦制動部を備える。この摩擦制動部は、ノブ本体部の第一端部および第二端部の内いずれかの端部に押圧操作が加わるのに伴って、被摩擦面により押し戻される向きに弾性変形する。そして、弾性復帰力による被摩擦面への押圧摩擦力により、押圧操作の解除に伴う揺動スイッチノブの中立位置へ向けた復帰動作を制動する。これにより、押圧操作を解除した時に揺動スイッチノブの揺動速度を下げることができ、非押圧側の端部がスイッチ素子に当接した時に発生する音を効果的に低減することが可能となる。 According to the above invention, the friction receiving portion that is swingable and displaceable integrally with the knob main body portion of the swing switch knob is formed, and the friction braking portion that comes into contact with the friction surface of the friction receiving portion is provided. The friction braking portion is elastically deformed in a direction to be pushed back by the friction target surface as a pressing operation is applied to either one of the first end portion and the second end portion of the knob main body portion. And the return operation | movement toward the neutral position of the rocking | swiveling switch knob accompanying cancellation | release of press operation is braked with the press frictional force to the to-be-rubbed surface by an elastic return force. As a result, the rocking speed of the rocking switch knob can be lowered when the pressing operation is released, and the sound generated when the non-pressing side end abuts against the switch element can be effectively reduced. Become.

この場合、摩擦受け部は、揺動スイッチノブの揺動支点部に関して第一端部側に形成された第一の摩擦受け部と、同じく第二端部側に形成された第二の摩擦受け部とを有し、摩擦制動部は第一の摩擦受け部と当接する第一の摩擦制動部と第二の摩擦受け部と当接する第二の摩擦制動部とを有する構成とすることができる。この構成によると、摩擦制動部および摩擦受け部が揺動スイッチノブの第一端部側と第二端部側にそれぞれ分けて設けられているため、押圧操作を解除した際の、揺動スイッチノブの中立位置への復帰動作を効果的に制動することができる。 In this case, the friction receiving portion includes a first friction receiving portion formed on the first end side with respect to the swing fulcrum portion of the swing switch knob, and a second friction receiving portion similarly formed on the second end side. And the friction braking portion can include a first friction braking portion that contacts the first friction receiving portion and a second friction braking portion that contacts the second friction receiving portion. . According to this configuration, since the friction braking portion and the friction receiving portion are provided separately on the first end side and the second end side of the swing switch knob, the swing switch when the pressing operation is released The return operation to the neutral position of the knob can be effectively braked.

また本発明は、ノブ本体部の周縁からスイッチ素子側に延出するノブ側壁部が形成され、支持体上には支持体壁部と対向配置される支持体壁部が立設され、支持体壁部とノブ側壁部との各対向面の一方が被摩擦面とされ、他方に被摩擦面に向けて突出する形で摩擦制動部が形成される構成にすることができる。この構成によると、ノブ本体部に形成されたノブ側壁部と、支持体に形成された支持体壁部のいずれか一方に被摩擦面が形成され、他方に摩擦制動部が形成される。そのため、ノブ側壁部と支持体壁部を非摩擦面または摩擦制動部に利用することが可能となる。例えば摩擦制動部を支持体壁部に形成し、被摩擦面をノブ側壁部に形成することができる。 According to the present invention, a knob side wall portion extending from the periphery of the knob main body portion to the switch element side is formed, and a support body wall portion arranged to face the support body wall portion is erected on the support body. One of the opposing surfaces of the wall portion and the knob side wall portion may be a friction surface, and the friction braking portion may be formed so that the other surface projects toward the friction surface. According to this configuration, the friction surface is formed on one of the knob side wall formed on the knob main body and the support wall formed on the support, and the friction brake is formed on the other. Therefore, the knob side wall and the support wall can be used as a non-friction surface or a friction braking portion. For example, the friction braking portion can be formed on the support wall portion, and the friction surface can be formed on the knob side wall portion.

また本発明は、ノブ本体部の揺動軸線方向における両端縁からスイッチ素子側に延出する形で１対のノブ主側壁部が形成され、支持体上には各ノブ主側壁部と対向する形で支持主壁部が立設され、各対向するノブ主側壁部と支持主壁部との対が揺動支点部により連結されてなり、摩擦制動部が支持主壁部の少なくとも一方に形成される構成にすることができる。この構成によると、比較的広く形成されたノブ主側壁部と支持主壁部との少なくとも一方に摩擦制動部を設けたで、揺動スイッチノブを制動しやすい。 Further, according to the present invention, a pair of knob main side wall portions are formed so as to extend from both end edges in the swing axis direction of the knob main body portion to the switch element side, and face each knob main side wall portion on the support. The support main wall portion is erected in a shape, and a pair of each of the opposing knob main side wall portion and the support main wall portion is connected by a swing fulcrum portion, and a friction braking portion is formed on at least one of the support main wall portions Can be configured. According to this configuration, since the friction braking portion is provided on at least one of the knob main side wall portion and the support main wall portion formed relatively wide, it is easy to brake the swing switch knob.

この場合、１対の支持主壁部が支持体上に予め定められた間隔で対向配置され、それら支持主壁部の外面に摩擦制動部が突出形成されるとともに、ノブ主側壁部が支持主壁部の外面側にて摩擦制動部を隠蔽する形で対向配置され、ノブ主側壁部の内面が被摩擦面とされるようにすることができる。この構成によると、摩擦制動部がノブ主側壁部によって隠蔽されるので、揺動スイッチノブがパネルに設けられている場合、そのパネルと揺動スイッチノブの隙間からユーザが内部を見ても摩擦制動部が見えず、高級感を出すことができる。 In this case, a pair of support main wall portions are arranged opposite to each other at a predetermined interval on the support, and a friction braking portion is formed to protrude on the outer surface of the support main wall portions, and the knob main side wall portion is supported by the support main wall portions. The friction braking portion can be concealed on the outer surface side of the wall portion so that the inner surface of the knob main side wall portion can be a friction surface. According to this configuration, since the friction braking portion is concealed by the knob main side wall portion, when the swing switch knob is provided on the panel, the user can see the friction from the gap between the panel and the swing switch knob. The braking part is not visible, giving a sense of quality.

例えば摩擦制動部は、ノブ側壁部側の対向面に向けて突出する片持ち梁形態の弾性爪部として形成することができる。この構成によると、片持ち梁形態の弾性爪部を第一端部側と第二端部側にそれぞれ分けて形成することが容易であり、揺動スイッチノブを効果的に制動できる。 For example, the friction braking portion can be formed as an elastic claw portion in the form of a cantilever that protrudes toward the opposing surface on the knob side wall portion side. According to this configuration, it is easy to form the cantilever-shaped elastic claw portion separately on the first end portion side and the second end portion side, and the swing switch knob can be effectively braked.

さらには、支持体壁部を厚さ方向に貫通する形で爪区画スリットが、爪基端側に位置する第一端から爪長手方向に延びて爪先端位置で方向転換するとともに、爪基端側に戻って第一端と爪幅方向に隔てられた第二端に至る形で形成され、弾性爪部は、爪区画スリットの内側に位置する舌状の爪本体と、爪本体の先端部においてノブ側壁部側に突出する摩擦突起部とを有するものとして形成されるようにしてもよい。この構成によると、支持体を例えば合成樹脂で成型した場合、支持体壁部と摩擦制動部を一体に成型できる。つまり、摩擦制動部を別体部材として設ける必要がなくなる。 Further, the nail partition slit extends in the nail longitudinal direction from the first end located on the nail base side in a form penetrating the support wall portion in the thickness direction, and changes its direction at the nail tip position. The elastic claw part is formed in a shape reaching the first end and the second end separated in the claw width direction, and the elastic claw part includes a tongue-like claw body located inside the claw partition slit, and a tip part of the claw body It may be made to have a friction projection part protruding to the knob side wall part side. According to this structure, when a support body is shape | molded, for example with a synthetic resin, a support body wall part and a friction braking part can be shape | molded integrally. That is, it is not necessary to provide the friction braking part as a separate member.

この場合、支持主壁部に対し第一の摩擦制動部が揺動支点部に関して基準方向における第一側に、第二の摩擦制動部が同じく第二側に形成することができる。この構成によると、揺動スイッチノブの第一端部と第二端部のどちらが押圧操作された場合でも、その押圧操作の解除に伴う揺動スイッチノブの中立位置への復帰動作を効果的に制動することができる。 In this case, the first friction braking portion can be formed on the first side in the reference direction with respect to the swing fulcrum portion, and the second friction braking portion can be formed on the second side with respect to the supporting main wall portion. According to this configuration, regardless of which one of the first end and the second end of the swing switch knob is pressed, it is possible to effectively return the swing switch knob to the neutral position when the press operation is released. Can be braked.

さらには、第一の摩擦制動部ないし第二の摩擦制動部は、ノブ本体部が中立状態のとき、ノブ主側壁部の内面に形成された被摩擦面によりその双方が弾性付勢状態とされるとともに、第一端部と第二端部との一方が押圧付勢状態となった場合に、ノブ本体部の揺動変位に伴い、ノブ主側壁部の非押圧付勢側において被摩擦面の端縁が第一の摩擦制動部ないし第二の摩擦制動部の対応する側のものから離脱する構成にしてもよい。このようにすると、揺動スイッチノブを押圧操作した場合に、非押圧付勢側の被摩擦面の端縁が摩擦制動部から離脱するため、摩擦力が加わらなくなり、揺動スイッチノブを押す力が軽くてすむ。 Furthermore, when the knob main body portion is in a neutral state, both the first friction braking portion and the second friction braking portion are elastically biased by the friction surface formed on the inner surface of the knob main side wall portion. In addition, when one of the first end portion and the second end portion is in a pressing biased state, the surface to be rubbed on the non-pressing biasing side of the knob main side wall portion with the swing displacement of the knob main body portion. The end edge may be separated from the corresponding side of the first friction braking part or the second friction braking part. In this way, when the swing switch knob is pressed, the edge of the friction surface on the non-pressing biasing side separates from the friction braking part, so that the frictional force is not applied and the force that pushes the swing switch knob. Is lighter.

この場合、ノブ主側壁部の非押圧付勢側において被摩擦面の端縁が第一の摩擦制動部ないし第二の摩擦制動部の対応する側のものから離脱するに伴い、非押圧付勢側の摩擦制動部が被摩擦面の延長よりも外側に突出する向きに変位する一方、押圧付勢側の摩擦制動部はこれと反対方向に連動変位するようにできる。この構成によると、非押圧付勢側の摩擦制動部は被摩擦面の延長よりも外側に突出する向きに変位して、当該被摩擦面の端縁から離脱する。これにより、非押圧付勢側の摩擦制動部による摩擦力が加わらなくなり、揺動スイッチノブを押す力が軽くてすむ。さらに、押圧付勢側の摩擦制動部はこれと反対方向に連動変位するため、押圧付勢側の摩擦制動部による摩擦力を低減もしくは無くすことができる。つまり上記構成によると、非押圧付勢側と押圧付勢側の双方において、摩擦制動部による摩擦力を低減できるため、軽い力で揺動スイッチノブを押すことが可能となる。また、押圧操作を解除した場合には、中立位置に復帰する揺動スイッチノブの端縁が非押圧付勢側と押圧付勢側の双方の摩擦制動部に当接するため、揺動スイッチノブが制動される。そのため、押圧操作を解除した際に、非押圧付勢側の端部とスイッチ素子との当接によって生じる音を低減できる。 In this case, the non-pressurizing bias is applied as the edge of the friction surface on the non-pressing biasing side of the knob main side wall part is separated from the corresponding one of the first friction braking part or the second friction braking part. The friction braking portion on the side is displaced in a direction protruding outward from the extension of the friction target surface, while the friction braking portion on the pressing bias side can be displaced in the opposite direction. According to this configuration, the friction braking portion on the non-pressing biasing side is displaced in a direction protruding outward from the extension of the friction target surface, and is detached from the edge of the friction target surface. As a result, the friction force by the friction braking portion on the non-pressing biasing side is not applied, and the force for pressing the swing switch knob is light. Further, since the friction braking portion on the pressing bias side is displaced in the opposite direction, the frictional force by the friction braking portion on the pressing bias side can be reduced or eliminated. That is, according to the above configuration, the frictional force generated by the friction braking portion can be reduced on both the non-pressing urging side and the pressing urging side, so that the swing switch knob can be pressed with a light force. In addition, when the pressing operation is released, the edge of the swing switch knob that returns to the neutral position comes into contact with the friction braking portions on both the non-pressing biasing side and the pressing biasing side. Braked. Therefore, when the pressing operation is released, it is possible to reduce the sound generated by the contact between the end portion on the non-pressing bias side and the switch element.

また、弾性爪部の先端側にノブ側壁部側に突出する摩擦突起部が形成されるとともに、摩擦突起部の被摩擦面の端縁に近い側の側面に、中立位置への復帰時に端縁が乗り上げるための傾斜状のガイド面を形成してもよい。このようにすると、揺動スイッチノブが中立位置へ復帰する時に、ノブ主側壁部の端縁と摩擦制動部との引っ掛かりを防止できる。 In addition, a friction projection that protrudes toward the knob side wall is formed on the tip side of the elastic claw, and the edge of the friction projection on the side close to the edge of the surface to be rubbed has an edge when returning to the neutral position. An inclined guide surface may be formed for riding up. In this way, when the swing switch knob returns to the neutral position, it is possible to prevent the end edge of the knob main side wall and the friction braking part from being caught.

例えば、第一の摩擦制動部をなす第一の弾性爪部と、第二の摩擦制動部をなす第二の弾性爪部とが、各々爪本体の基端側が揺動支点部側に位置し、先端側が基準方向にて互いに反対向きに延びるように配置され、それら２つの爪本体部を区画する爪区画スリットの第一端同士及び第二端同士が、基準方向にて互いに対向する位置関係で形成され、爪区画スリットの第一端同士の間に位置する部分と、同じく第二端同士の間に位置する部分とが、２つの爪本体部を連動変位させるためのねじれ支点部を形成するようにできる。このようにすると、支持体主壁部と、摩擦制動部と、ねじれ支点部とを一体に形成することが可能になる。すなわち、摩擦制動部と、ねじれ支点部とを別体部材とする必要がなくなる。 For example, a first elastic claw portion forming a first friction braking portion and a second elastic claw portion forming a second friction braking portion are respectively located at the base end side of the claw body on the swing fulcrum portion side. The positional relationship in which the first ends and the second ends of the nail partition slits that divide the two nail main body portions are opposed to each other in the reference direction is arranged so that the tip ends extend in opposite directions in the reference direction. The portion located between the first ends of the nail partition slit and the portion located between the second ends form a twisted fulcrum for interlocking displacement of the two nail body portions. You can do that. If it does in this way, it will become possible to form a support body main wall part, a friction braking part, and a twist fulcrum part integrally. That is, it is not necessary to make the friction braking portion and the torsion fulcrum portion separate members.

本発明の実施形態を、図面を参照しながら以下に説明する。
図１は本発明に係る双方向スイッチ１が設けられたフロントパネル１２の正面図である。このようにフロントパネル１２には双方向スイッチ１の他、各種スイッチ群６０とディスプレイ５０とを備え、双方向スイッチ１によって、例えば車内エアコンの温度を設定できるようになっている。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a front view of a front panel 12 provided with a bidirectional switch 1 according to the present invention. As described above, the front panel 12 includes the bidirectional switch 1 and various switch groups 60 and the display 50, and the bidirectional switch 1 can set the temperature of the air conditioner in the vehicle, for example.

次に、双方向スイッチ１の分解斜視図を図２に示し、断面図を図３に示す。このように双方向スイッチ１は、支持体９と、第一のスイッチ素子１１ａおよび第二のスイッチ素子１１ｂと、揺動支点部３を介して揺動自在にされた揺動スイッチノブ２と、ノブ復帰手段７と、摩擦制動部４とを備える。 Next, an exploded perspective view of the bidirectional switch 1 is shown in FIG. 2, and a sectional view is shown in FIG. As described above, the bidirectional switch 1 includes the support body 9, the first switch element 11a and the second switch element 11b, the swing switch knob 2 which is swingable via the swing support point 3, A knob return means 7 and a friction braking unit 4 are provided.

より詳しくは、第一及び第二のスイッチ素子１１ａ，１１ｂは、支持体９上に予め定められた基準方向に所定の間隔を隔てて配置され、押圧付勢及び付勢解除により導通状態が切り替わるものである。また、揺動スイッチノブ２は、揺動長手方向が基準方向と一致するよう支持体９に揺動支点部３を介して揺動可能に取り付けられるノブ本体部２ａを有し、第一端部２ｄ側に第一のスイッチ素子１１ａを付勢する第一スイッチ付勢部２ｆが形成され、第二端部２ｅ側に第二のスイッチ素子１１ｂを付勢する第二スイッチ付勢部２ｇが形成されている。そして、ノブ本体部２ａの第一端部２ｄ又は第二端部２ｅに押圧操作が加わるに伴い、第一又は第二のスイッチ付勢部２ｆ，２ｇが対応するスイッチ素子１１ａ，１１ｂに向けて接近する向きに揺動変位する。本実施例では図３に示すように、第一又は第二のスイッチ付勢部２ｆ，２ｇの裏面にガイド部１０が設けられており、このガイド部１０の先端に押される形で各スイッチ素子１１ａ，１１ｂが押圧付勢される。 More specifically, the first and second switch elements 11a and 11b are arranged on the support 9 at a predetermined interval in a predetermined reference direction, and the conductive state is switched by pressing biasing and biasing cancellation. Is. The swing switch knob 2 has a knob body 2a that is swingably attached to the support 9 via a swing fulcrum 3 so that the swing longitudinal direction coincides with the reference direction. A first switch biasing portion 2f for biasing the first switch element 11a is formed on the 2d side, and a second switch biasing portion 2g for biasing the second switch element 11b is formed on the second end portion 2e side. Has been. Then, as the pressing operation is applied to the first end portion 2d or the second end portion 2e of the knob body 2a, the first or second switch urging portions 2f, 2g are directed toward the corresponding switch elements 11a, 11b. Oscillating displacement in the approaching direction. In this embodiment, as shown in FIG. 3, a guide portion 10 is provided on the back surface of the first or second switch urging portions 2f and 2g, and each switch element is pushed by the tip of the guide portion 10. 11a and 11b are pressed and urged.

ノブ復帰手段７は、押圧操作により第一又は第二のスイッチ付勢部２ｆ，２ｇのいずれかが対応するスイッチ素子１１ａ，１１ｂに向けて揺動変位するに伴い弾性変形し、押圧操作の解除に伴い弾性復帰することにより、揺動スイッチノブ２を押圧操作時とは逆向きに揺動変位させ、スイッチ付勢部２ｆ，２ｇを対応するスイッチ素子１１ａ，１１ｂから離間させて中立位置に復帰させる。本実施例では、ノブ復帰手段７はバネ部材として構成されている。 The knob return means 7 is elastically deformed as the first or second switch urging portion 2f, 2g swings toward the corresponding switch element 11a, 11b by the pressing operation, and the pressing operation is released. Accordingly, the swinging switch knob 2 is swung and displaced in the direction opposite to that during the pressing operation, and the switch urging portions 2f and 2g are separated from the corresponding switch elements 11a and 11b to return to the neutral position. Let In this embodiment, the knob return means 7 is configured as a spring member.

摩擦制動部４は、ノブ本体部２ａと一体に揺動変位可能にされた摩擦受け部（本実施例では、ノブ主側壁部２ｂ）の被摩擦面（本実施例では、ノブ主側壁部２ｂの内面）に当接するとともに、ノブ本体部２ａのいずれかの端部２ｄ，２ｅに押圧操作が加わるに伴い、被摩擦面により押し戻される向きに弾性変形し、その弾性復帰力による被摩擦面への押圧摩擦力により、押圧操作の解除に伴う揺動スイッチノブ２の中立位置へ向けた復帰動作を制動する。 The friction braking portion 4 is a friction receiving surface (in this embodiment, the knob main side wall portion 2b) of a friction receiving portion (in this embodiment, the knob main side wall portion 2b) that is swingably displaced integrally with the knob main body portion 2a. The inner surface of the knob main body 2a is elastically deformed in a direction to be pushed back by the frictional surface as the end portion 2d, 2e of the knob main body 2a is pressed, and the elastic recovery force returns to the frictional surface. With the pressing frictional force, the return operation toward the neutral position of the swing switch knob 2 accompanying the release of the pressing operation is braked.

第一端部２ｄまたは第二端部２ｅを押圧操作すると、揺動スイッチノブ２が揺動し、第一又は第二のスイッチ素子１１ａ，１１ｂが押圧付勢される。その状態で押圧操作を解除すると、従来の双方向スイッチでは、ノブ復帰手段７の弾性復帰力によって揺動スイッチノブが中立位置に復帰し、その反動で非押圧付勢側のスイッチ素子にガイド部１０が当接してタタキ音が発生していた。これに対して本発明は、上述した摩擦制動部４の押圧摩擦力により揺動スイッチノブ２を制動するため、タタキ音を効果的に低減できる。また、上述したグリース等の緩衝材を使用することもないので、スイッチ阻止１１ａ，１１ｂに悪影響を与えなくてすむ。 When the first end 2d or the second end 2e is pressed, the swing switch knob 2 swings and the first or second switch elements 11a and 11b are pressed and biased. When the pressing operation is released in this state, in the conventional bidirectional switch, the swinging switch knob is returned to the neutral position by the elastic return force of the knob return means 7, and by the reaction, the guide portion is connected to the switch element on the non-pressing bias side. No. 10 contacted and a rattling sound was generated. On the other hand, the present invention brakes the swing switch knob 2 by the pressing frictional force of the friction braking portion 4 described above, so that it is possible to effectively reduce the rattling noise. Further, since the above-described cushioning material such as grease is not used, there is no need to adversely affect the switch blocking 11a and 11b.

一方、図２に示すように、ノブ本体本体部２ａの周縁からはスイッチ素子１１ａ，１１ｂに延出する一対のノブ主側壁部２ｂ，２ｃが形成され、支持体９の周縁から立設する支持主壁部９ａ，９ｂと対向するように配置されている。そして、対向するノブ主側壁部２ｂ，２ｃと支持主壁部９ａ，９ｂの対が揺動支点部３により連結されている。より詳しくは、一方の支持主壁部９ａ，９ｂに支点突起３ａが形成され、ノブ主側壁部２ｂ，２ｃに支点係合孔３ｂが形成され、支点突起３ａが支点係合孔３ｂに係合することで揺動支点部３を構成している。また、支持主壁部９ａ，９ｂのうち一方の支持主壁部９ａに摩擦制動部４が形成されている。 On the other hand, as shown in FIG. 2, a pair of knob main side walls 2b and 2c extending from the periphery of the knob main body 2a to the switch elements 11a and 11b are formed. It arrange | positions so that the main wall parts 9a and 9b may be opposed. A pair of opposing knob main side wall portions 2 b and 2 c and supporting main wall portions 9 a and 9 b are connected by a swing fulcrum portion 3. More specifically, a fulcrum projection 3a is formed on one of the support main wall portions 9a and 9b, a fulcrum engagement hole 3b is formed on the knob main side wall portions 2b and 2c, and the fulcrum projection 3a engages with the fulcrum engagement hole 3b. By doing so, the oscillating fulcrum portion 3 is configured. The friction braking portion 4 is formed on one of the support main wall portions 9a and 9b.

図４の拡大図に示すように、摩擦受け部（本実施例では、ノブ主側壁部２ｂ）は、揺動支点部３に関して第一端部２ｄ側に形成された第一の摩擦受け部２ｂ１と、第二端部２ｅ側に形成された第二の摩擦受け部２ｂ２とを有し、摩擦制動部４は第一の摩擦受け部２ｂ１と当接する第一の摩擦制動部４ａと、第二の摩擦受け部２ｂ２と当接する第二の摩擦制動部４ｂとを有する。 As shown in the enlarged view of FIG. 4, the friction receiving portion (in this embodiment, the knob main side wall portion 2 b) is a first friction receiving portion 2 b 1 formed on the first end portion 2 d side with respect to the swing fulcrum portion 3. And a second friction receiving portion 2b2 formed on the second end portion 2e side. The friction braking portion 4 includes a first friction braking portion 4a that contacts the first friction receiving portion 2b1, and a second friction receiving portion 2b1. And a second friction braking portion 4b that contacts the friction receiving portion 2b2.

摩擦制動部４は、ノブ側壁部２ｂ側の対向面に向けて突出する片持ち梁形態の弾性爪部として形成されている。より詳しくは、摩擦制動部４は、第一端部２ｄ側に位置する第一爪本体５ａと、第二端部２ｅ側に位置する第二爪本体５ｂと、第一爪本体５ａの先端部においてノブ側壁部２ｂ側へ向けて突出する第一の摩擦突起部６ａと、第二爪本体５ｂの先端部においてノブ側壁部２ｂ側へ向けて突出する第二の摩擦突起部６ｂと、第一および第二爪本体５ａ，５ｂと支持主壁部９ａとを繋ぐねじれ支点部８とを備える。また、第一および第二の摩擦突起部６ａ，６ｂには、傾斜状のガイド面６ｃ，６ｄと、端面６ｅ，６ｆがそれぞれ形成されている。 The friction braking part 4 is formed as an elastic claw part in the form of a cantilever projecting toward the opposing surface on the knob side wall part 2b side. More specifically, the friction braking unit 4 includes a first claw body 5a located on the first end 2d side, a second claw body 5b located on the second end 2e side, and a tip portion of the first claw body 5a. A first friction protrusion 6a protruding toward the knob side wall 2b, a second friction protrusion 6b protruding toward the knob side wall 2b at the tip of the second claw body 5b, And a torsion fulcrum portion 8 connecting the second claw main bodies 5a, 5b and the support main wall portion 9a. In addition, inclined guide surfaces 6c and 6d and end surfaces 6e and 6f are formed on the first and second friction projections 6a and 6b, respectively.

次に、双方向スイッチ１の別の実施例を図５に示す。この実施例では、支持主壁部９ａと、第一および第二の爪本体５ａ，５ｂと、ねじれ支点部８と、第一および第二の摩擦突起部６ａ，６ｂが一体に構成されている。すなわち、支持主壁部９ａを厚さ方向に貫通する形で爪区画スリット１４が、爪基端側に位置する第一端１４ａから爪長手方向に延びて爪先端位置で方向転換し、爪基端側に戻って第一端１４ａと爪幅方向に隔てられた第二端１４ｂに至る形で形成されている。また、ねじれ支点部８に関して対象となる方向にも、第二の爪本体５ｂが、爪区画スリット１４により支持主壁部９ａから区画される形で形成されている。このような構成にすると、例えば合成樹脂を使った成型方法によって支持体９（すなわち、支持主壁部９ａ）を成型すれば、爪本体５ａ，５ｂと、ねじれ支点部８と、摩擦突起部６ａ，６ｂとを同時に形成することが可能となる。つまり、爪本体５ａ，５ｂ等を別体部材として用意する必要がなくなる。 Next, another embodiment of the bidirectional switch 1 is shown in FIG. In this embodiment, the support main wall portion 9a, the first and second claw bodies 5a and 5b, the torsion fulcrum portion 8, and the first and second friction projections 6a and 6b are integrally formed. . That is, the nail partition slit 14 extends in the nail longitudinal direction from the first end 14a located on the nail base end side so as to penetrate the support main wall portion 9a in the thickness direction, and changes its direction at the nail tip position. It is formed so as to return to the end side and reach the second end 14b separated from the first end 14a in the claw width direction. Further, the second claw body 5b is also formed in the target direction with respect to the torsion fulcrum portion 8 so as to be partitioned from the support main wall portion 9a by the claw partition slit 14. With such a configuration, for example, if the support 9 (that is, the support main wall portion 9a) is molded by a molding method using a synthetic resin, the claw bodies 5a and 5b, the twist fulcrum portion 8, and the friction projection portion 6a. , 6b can be formed simultaneously. That is, it is not necessary to prepare the nail bodies 5a and 5b as separate members.

なお図５に示すように、支持体９上には、一対の支持主壁部９ａ，９ｂの各両端を、対応する支持体端部壁部９ｃ，９ｄにてそれぞれ連結することにより枠状のスイッチ支持部が形成されている。また揺動スイッチノブ２は、ノブ本体部２ａの揺動長手方向の両端縁からスイッチ素子１１ａ，１１ｂに延出する形で、一対のノブ端部壁２ｆ，２ｇが形成されている。そして揺動スイッチノブ２は、これらノブ主側壁部２ｂ，２ｃ及びノブ端部壁２ｆ，２ｇにより、ノブ本体部２ａの周縁を取り囲む形でスイッチ支持部を覆うノブフード部として構成されている。これにより、フロントパネル１２（図１参照）とノブ本体部２ａの隙間をユーザが覗いた場合でも、内部に形成された揺動支点部３や摩擦制動部４ａ，４ｂが見えなくなり、高級感を増すことができる。 In addition, as shown in FIG. 5, on the support body 9, both ends of a pair of support main wall part 9a, 9b are each connected by the corresponding support body end part wall part 9c, 9d, respectively, and frame shape is carried out. A switch support is formed. The swing switch knob 2 is formed with a pair of knob end walls 2f and 2g so as to extend from both end edges in the swing longitudinal direction of the knob body 2a to the switch elements 11a and 11b. The swing switch knob 2 is configured as a knob hood portion that covers the switch support portion so as to surround the periphery of the knob main body portion 2a by the knob main side wall portions 2b and 2c and the knob end portion walls 2f and 2g. As a result, even when the user looks into the gap between the front panel 12 (see FIG. 1) and the knob main body 2a, the swing fulcrum 3 and the frictional brakes 4a and 4b formed inside are not visible, giving a high-class feeling. Can be increased.

さらには、揺動支点部３は、支持主壁部９ａ，９ｂの基準方向における中間位置に形成され、支持主壁部９ａ，９ｂの上縁面が揺動支点部３に対応する位置にて高さ極大となる山形に形成されている。このように山形に形成することにより、揺動スイッチノブ２の揺動ストロークを規制することが可能となる。 Furthermore, the swing fulcrum portion 3 is formed at an intermediate position in the reference direction of the support main wall portions 9 a and 9 b, and the upper edge surface of the support main wall portions 9 a and 9 b is at a position corresponding to the swing fulcrum portion 3. It is formed in a mountain shape with a maximum height. By forming the mountain shape in this way, the swing stroke of the swing switch knob 2 can be restricted.

次に、双方向スイッチ１の動作説明図を図６，図７に示す。まず、図６（Ａ）の左図（側面図）および右図（横断面図）に示すように、中立位置では第一の摩擦突起部６ａと第二の摩擦突起部６ｂの双方がノブ主側壁部２ｂの被摩擦面Ｓ（内面）に当接し、弾性付勢状態とされる。すなわち、第一の爪本体５ａ及び第二の爪本体５ｂの双方がノブ主側壁部２ｂへ向けて弾性付勢されており、この弾性付勢力により、摩擦突起部６ａ，６ｂが被摩擦面Ｓに押し付けられた形になっている。 Next, operation explanatory diagrams of the bidirectional switch 1 are shown in FIGS. First, as shown in the left diagram (side view) and right diagram (transverse view) in FIG. 6A, both the first friction projection 6a and the second friction projection 6b are the main knobs in the neutral position. It abuts against the surface to be rubbed S (inner surface) of the side wall 2b and is in an elastically biased state. That is, both the first claw body 5a and the second claw body 5b are elastically biased toward the knob main side wall 2b, and the friction projections 6a and 6b are caused to be rubbed by the elastic biasing force S. The shape is pressed against.

この状態から、例えば第二端部２ｅを押圧操作すると図６（Ｂ）に進み、さらに押圧すると図７（Ａ）の状態になる。これらの図に示すように、第二の爪本体部５ｂはノブ主側壁部２ｂの被摩擦面Ｓにより内側へ押し戻される向きに弾性変形する。 From this state, for example, when the second end 2e is pressed, the process proceeds to FIG. 6B, and when further pressed, the state shown in FIG. 7A is obtained. As shown in these drawings, the second claw main body portion 5b is elastically deformed in a direction to be pushed back inward by the friction surface S of the knob main side wall portion 2b.

より詳しくは、第二端部２ｅを押圧すると、ノブ主側壁部２ｂの非押圧付勢側（この場合は第一端部２ｄ側）において被摩擦面Ｓの端縁Ｌが第一の摩擦制動部４ａから離脱する。すなわち、摩擦突起部６ａが被摩擦面Ｓの延長よりも外側に突出する向きに変位する。これにより、第一の摩擦制動部４ａによる押圧摩擦力が被摩擦面Ｓに加わらなくなり、より軽い力で第一端部２ｅを押圧付勢できるようになる。また、図７（Ａ）に示すように、押圧付勢側である第二の摩擦制動部４ｂは、これと反対側に連動変位する。すなわち、第一の爪本体５ａが外側へ突出するため、ねじれ支点部８がねじれ変形し、第二の爪本体５ｂが内側へ押し戻されるように弾性変形する。そのため、第二の摩擦制動部４ｂ側においても、被摩擦面Ｓへの押圧摩擦力が軽減されるようになる。これにより、軽い力で第二端部２ｅを押圧付勢することが可能となる。 More specifically, when the second end 2e is pressed, the edge L of the friction surface S is the first friction braking on the non-pressing biasing side (in this case, the first end 2d side) of the knob main side wall 2b. Detach from part 4a. That is, the friction projection 6a is displaced in a direction protruding outward from the extension of the friction surface S. As a result, the pressing friction force by the first friction braking portion 4a is not applied to the friction surface S, and the first end portion 2e can be pressed and biased with a lighter force. Further, as shown in FIG. 7A, the second friction braking portion 4b, which is the pressing bias side, is interlocked and displaced to the opposite side. That is, since the first claw body 5a protrudes outward, the torsion fulcrum portion 8 is torsionally deformed and elastically deformed so that the second claw body 5b is pushed back inward. Therefore, also on the second friction braking part 4b side, the pressing frictional force on the friction surface S is reduced. Thereby, the second end 2e can be pressed and biased with a light force.

押圧操作を解除すると、上述のノブ復帰手段７により揺動スイッチノブ２が中立位置に復帰する。このとき、非付勢側（すなわち、第一端部２ｄ側）の被摩擦面Ｓに第一の摩擦突起部６ａが当接することにより、ノブ主側壁部２ｂに押圧摩擦力が加わる。さらに、第二の爪本体５ｂがねじれ復帰するため、第二の摩擦突起部６ｂも被摩擦面Ｓに当接し、ノブ主側壁部２ｂに押圧摩擦力が加わる。これら第一および第二の摩擦突起部６ａ，６ｂの押圧摩擦力により、中立位置へ復帰する揺動スイッチノブ２が急速に制動される。 When the pressing operation is released, the swing switch knob 2 is returned to the neutral position by the knob return means 7 described above. At this time, when the first friction projection 6a abuts against the friction surface S on the non-biasing side (that is, the first end portion 2d side), a pressing friction force is applied to the knob main side wall 2b. Furthermore, since the second claw body 5b is torsionally restored, the second friction projection 6b is also brought into contact with the friction surface S, and a pressing friction force is applied to the knob main side wall 2b. The swing switch knob 2 that returns to the neutral position is rapidly braked by the pressing frictional force of the first and second friction projections 6a and 6b.

次に、図８〜図１０を用いて双方向スイッチ１の動作説明をする。まず、図８では揺動スイッチノブ２が中立位置にされている。図８（Ｂ）の横断面図に示すように中立位置では、第一および第二の爪本体５ａ，５ｂによって第一の摩擦突起部６ａと第二の摩擦突起部６ｂの双方が被摩擦面Ｓへ向けて弾性付勢されている。このとき、図８（Ｃ）のＡ−Ａ矢視図に示すように、被摩擦面Ｓの端縁Ｌは、ガイド面６ｃ上に位置している。 Next, the operation of the bidirectional switch 1 will be described with reference to FIGS. First, in FIG. 8, the swing switch knob 2 is in the neutral position. As shown in the cross-sectional view of FIG. 8B, in the neutral position, both the first friction projection 6a and the second friction projection 6b are rubbed by the first and second claw bodies 5a and 5b. Elastically biased toward S. At this time, as shown in the AA arrow view of FIG. 8C, the edge L of the friction surface S is located on the guide surface 6c.

その後、第一端部２ｄを押圧付勢すると、図９（Ａ）に示すように揺動スイッチノブ２が揺動する。このとき、図９（Ｂ）の横断面図に示すように、非押圧付勢側である第二の摩擦突起部６ｂは被摩擦面Ｓの端縁Ｌから離脱し、外側に突出する向きに変位する。そして、ねじれ支点８がねじれ変形し、押圧付勢側である第一の爪本体５ａおよび第一の摩擦突起部６ａは被摩擦面Ｓにより押し戻される向きに弾性変位する。これにより、第一および第二の摩擦突起部６ａ，６ｂによる被摩擦面Ｓへの押圧摩擦力が減少され、軽い力で第一端部２ｄを押圧付勢できるようになる。このとき、図９（Ｃ）のＢ−Ｂ矢視図に示すように、第一の摩擦突起部６ａの端面６ｅは被摩擦面Ｓに接するか、または図示しないが被摩擦面Ｓよりも内側に位置するようになっている。 Thereafter, when the first end 2d is pressed and urged, the swing switch knob 2 swings as shown in FIG. At this time, as shown in the cross-sectional view of FIG. 9B, the second friction projection 6b on the non-pressing biasing side is detached from the edge L of the friction surface S and protrudes outward. Displace. Then, the torsion fulcrum 8 is torsionally deformed, and the first claw body 5a and the first friction projection 6a on the pressing bias side are elastically displaced in a direction to be pushed back by the friction surface S. As a result, the pressing friction force applied to the friction surface S by the first and second friction projections 6a and 6b is reduced, and the first end portion 2d can be pressed and biased with a light force. At this time, the end surface 6e of the first friction projection 6a is in contact with the friction surface S or inside the friction surface S (not shown), as shown in FIG. It is supposed to be located in.

次に押圧操作を解除すると、上述のノブ復帰手段７によって揺動スイッチノブ２が中立位置に復帰する。すなわち、第一端部２ｄは図１０（Ａ）の上向きに弾性付勢され、第二端部２ｅは下向きに揺動する。このとき、第一および第二の爪本体５ａ，５ｂがねじれ復帰するため、図１０（Ｂ）の横断面図に示すように、第一および第二の摩擦突起部６ａ，６ｂの双方が被摩擦面Ｓに当接し、この押圧摩擦力によって揺動スイッチノブ２が急速に制動される。より詳しくは、図１０（Ｃ）のＣ−Ｃ矢視図に示すように、第一の摩擦突起部６ａのガイド面６ｃに被摩擦抵面Ｓの端縁Ｌが乗り上げ、また、図１０（Ｄ）のＤ−Ｄ矢視図に示すように、第二の摩擦突起部６ｂのガイド面６ｄに被摩擦抵抗面Ｓの端縁Ｌが乗り上げる形になっている。このように傾斜状のガイド面６ｄが形成されているため、下向きに変位するノブ主側壁部２ｂの端縁Ｌが第二の摩擦突起部６ｂに引っ掛からず、スムーズに変位できる。 Next, when the pressing operation is released, the swing switch knob 2 is returned to the neutral position by the knob return means 7 described above. That is, the first end portion 2d is elastically biased upward in FIG. 10A, and the second end portion 2e swings downward. At this time, since the first and second claw bodies 5a and 5b are torsionally restored, both the first and second friction projections 6a and 6b are covered as shown in the cross-sectional view of FIG. The rocking switch knob 2 comes into contact with the friction surface S, and the rocking switch knob 2 is rapidly braked by this pressing frictional force. More specifically, as shown in a CC arrow view of FIG. 10 (C), the edge L of the frictional contact surface S rides on the guide surface 6c of the first friction projection 6a, and FIG. As shown in the DD arrow view of D), the edge L of the friction-resistant surface S rides on the guide surface 6d of the second friction projection 6b. Since the inclined guide surface 6d is formed in this way, the edge L of the knob main side wall 2b that is displaced downward is not caught by the second friction projection 6b and can be smoothly displaced.

なお、本発明のねじれ支点部８、爪部５ａ，５ｂ、摩擦突起部６ａ，６ｂは、上述したように支持主壁部９ａと一体に形成することができるが、図１１に示すように別体部材として構成することも可能である。図１１では、円柱状のねじれ支点部８と、係合孔８ａが形成された爪本体５とをそれぞれ用意し、ねじれ支点部８を係合孔８ａに係合している。このようにすると、ねじれ応力が加わってもねじれ支点部８が破損しにくくなる。 Note that the torsion fulcrum portion 8, the claw portions 5a and 5b, and the friction projections 6a and 6b of the present invention can be formed integrally with the support main wall portion 9a as described above, but as shown in FIG. It can also be configured as a body member. In FIG. 11, a cylindrical torsion fulcrum portion 8 and a claw body 5 having an engagement hole 8a are prepared, and the torsion fulcrum portion 8 is engaged with the engagement hole 8a. If it does in this way, even if torsional stress will be added, the torsion fulcrum part 8 will become difficult to break.
