Description

本発明は、***作部材の操作に節度を与える節度装置に関する。 The present invention relates to a moderation device that gives moderation to the operation of an operated member.

従来、自動車の各種コントロールに使用されるロータリスイッチ装置は、例えば、特許文献１に開示されているスイッチ装置のように、ケース内面に形成された山部及び谷部を交互に有する節度面部と、ケース内のロータ側に設けられたコイルばね及びこのコイルばねにより節度面部に当接するように付勢されたボールとからなる節度機構を有している。 Conventionally, a rotary switch device used for various controls of an automobile, for example, a moderation surface portion having alternating ridges and valleys formed on the inner surface of the case, like the switch device disclosed in Patent Document 1, It has a moderation mechanism comprising a coil spring provided on the rotor side in the case and a ball urged so as to abut on the moderation surface portion by the coil spring.

このような構成の節度機構によれば、使用者が操作ノブを回動してスイッチ操作を行う場合、ロータの回動に伴ってボールが山部を超えて谷部に移動し、この谷部に落ち込む。すなわち、ボールが山部を超える前後において操作ノブに与えられるフィードバック力が変化する。これにより、操作ノブ（***作部材）の回動に節度が与えられている。
実開平５−９４９２２号公報 According to the moderation mechanism having such a configuration, when the user performs the switch operation by rotating the operation knob, the ball moves over the peak portion to the valley portion with the rotation of the rotor. Depressed. That is, the feedback force applied to the operation knob changes before and after the ball exceeds the mountain. Thereby, moderation is given to rotation of the operation knob (operated member).

上述の特許文献１のものでは、***作部材を回動した時に節度が与えられる回動角度（以下、節度角度という）が、節度面の山部及び谷部の形成ピッチ（角度ピッチ）に制約されてしまう問題がある。この問題を解決するものとして、図４に示す構成の節度装置が考えられている。 In the thing of the above-mentioned patent document 1, the rotation angle (henceforth a moderation angle) by which moderation is given when a to-be-operated member is rotated is restricted by the formation pitch (angle pitch) of the peak part and valley part of a moderation surface. There is a problem that will be done. As a solution to this problem, a moderation device having the configuration shown in FIG. 4 is considered.

図８において、例えばインストルメントパネル１の裏面側の適宜部位に取り付けられた装置本体２には、***作部材としての軸３が回動可能に支承されている。この軸３においてインストルメントパネル１の表面側に突出する前端部（図では右端部）には、操作部４が軸３と一体回動する形態に取り付けられている。さらに、この軸３の後端には、操作部４の回動位置を検出するためのロータリーエンコーダ５のディスク５ａが軸３と一体回動する形態に取り付けられている。 In FIG. 8, for example, a shaft 3 as an operated member is rotatably supported on the apparatus main body 2 attached to an appropriate part on the back side of the instrument panel 1. An operating portion 4 is attached to a front end portion (right end portion in the figure) protruding from the surface side of the instrument panel 1 in the shaft 3 so as to rotate integrally with the shaft 3. Further, a disk 5 a of the rotary encoder 5 for detecting the rotational position of the operation unit 4 is attached to the rear end of the shaft 3 so as to rotate integrally with the shaft 3.

さらに、軸３の後端側に被吸着部６が軸３と一体回動する形態に設けられており、この被吸着部材６の右端面には磁性板からなる被吸着体６ａが取着されている。この被吸着体６ａの前方部には、電磁石７が、軸３とは無関係に回動可能に、且つ微小距離で軸方向への移動可能に設けられている。この電磁石７と装置本体２との間には、合成樹脂からなるばね板８、８が設けられており、このばね板８、８の一端は前記装置本体２に取着され、他端は前記電磁石７に取着されている。このばね板８、８は、軸３の回動に対して抵抗を与えるものである。なお軸３には適宜の操作対象物が付設あるいは連結される。 Further, the attracted portion 6 is provided on the rear end side of the shaft 3 so as to rotate integrally with the shaft 3, and the attracted member 6 a made of a magnetic plate is attached to the right end surface of the attracted member 6. ing. An electromagnet 7 is provided at the front portion of the attracted member 6a so as to be rotatable independently of the shaft 3 and to be movable in the axial direction at a minute distance. Between the electromagnet 7 and the apparatus body 2, spring plates 8 and 8 made of synthetic resin are provided. One end of each of the spring plates 8 and 8 is attached to the apparatus body 2, and the other end is the It is attached to the electromagnet 7. The spring plates 8 and 8 give resistance to the rotation of the shaft 3. An appropriate operation object is attached to or connected to the shaft 3.

この図の構成において、通常は、電磁石７が断電されており、操作部４が使用者により回動操作されると、軸３、ディスク５ａ、被吸着部６が一体回動する。そして、操作部４が所定角度回動されると、ロータリーエンコーダ５がこの所定角度を検出し、これに基づいて図示しない制御部が電磁石７に通電する。すると、電磁石７と被吸着体６ａとが吸着状態となって当該電磁石７、被吸着体６ａ、軸３、操作部４が一体化状態となる。従って、この状態から使用者が操作部４をさらに回動すると、板ばね８、８の他端がその回動方向へ弾性変形することによって復元方向へばね力を発生し、使用者が回動抵抗を受け、電磁石が断電したときに回動抵抗がなくなる。回動抵抗の差により節度が与えられる。 In the configuration shown in this figure, the electromagnet 7 is normally disconnected, and when the operation unit 4 is rotated by the user, the shaft 3, the disk 5a, and the attracted portion 6 rotate together. When the operation unit 4 is rotated by a predetermined angle, the rotary encoder 5 detects the predetermined angle, and based on this, a control unit (not shown) energizes the electromagnet 7. Then, the electromagnet 7 and the object to be adsorbed 6a are in an adsorbed state, and the electromagnet 7, the object to be adsorbed 6a, the shaft 3, and the operation unit 4 are in an integrated state. Accordingly, when the user further rotates the operation unit 4 from this state, the other ends of the leaf springs 8 and 8 are elastically deformed in the rotation direction, thereby generating a spring force in the restoring direction, and the user rotates. When resistance is applied and the electromagnet is turned off, the rotational resistance disappears. Moderation is given by the difference in rotational resistance.

しかし、この構成では、合成樹脂製のばね板８、８を使用するため、ばね機能を奏するための形状の設定が難しいとともに、ばね力設定のための材料選定も難しく、総じて節度の設定が難しいといった問題があった。また、節度の滑らか度合いとか、急激度合いなどの微妙な設定も困難であった。 However, in this configuration, since the spring plates 8 and 8 made of synthetic resin are used, it is difficult to set a shape for achieving a spring function, it is also difficult to select a material for setting the spring force, and it is generally difficult to set the moderation. There was a problem. In addition, it is difficult to set subtle settings such as the smoothness degree of moderation and the abrupt degree.

更に、上記構成では、操作部４（或は***作部材）を所定の回動位置で停止させるには、例えば、インストルメントパネル１に、操作部４の回動を規制するための係止部を設ける必要がある。つまり、この節度装置は、単に節度を付与するにすぎず、操作部４の回動範囲を規制することは考慮されていないのである。 Furthermore, in the above configuration, in order to stop the operation unit 4 (or the operated member) at a predetermined rotation position, for example, the instrument panel 1 is provided with a locking unit for restricting the rotation of the operation unit 4. It is necessary to provide. That is, this moderation device merely provides moderation, and it is not considered to restrict the rotation range of the operation unit 4.

本発明は上記事情に鑑みてなされたものであり、その目的は、外部からの操作力により回動操作される***作部材を備えた節度装置であって、節度角度の設定や節度の強弱などの設定を容易にすることができると共に、***作部材を任意の回動範囲に規制することができる節度装置を提供することにある。 The present invention has been made in view of the above circumstances, and an object thereof is a moderation device including an operated member that is rotated by an external operation force, such as setting of a moderation angle, strength of moderation, and the like. It is an object of the present invention to provide a moderation device that can facilitate the setting and can regulate the operated member within an arbitrary rotation range.

本発明は、装置本体に回動操作可能に設けられ、外部からの操作力により操作される***作部材と、略Ｖ形の凹面部を有する回動抵抗受部と、ばね及び押圧部材を有し、前記ばねのばね力により、前記押圧部材を前記回動抵抗受部の凹面部に対し押圧して回動抵抗を与えるための抵抗付与手段と、前記回動抵抗受部に前記凹面部の両端部側に位置して設けられ、前記抵抗付与手段に対し当接して係止する一対の回動規制部と、前記装置本体に設けられた電磁石と、前記***作部材の回動位置を検出する回動位置検出手段と、この位置検出手段により検出された前記***作部材の回動位置に応じて前記電磁石を通断電制御する制御手段とを備え、前記回動抵抗受部と前記抵抗付与手段との一方を、前記***作部材と一体回動可能に設けると共に、他方を、前記電磁石の断電時に前記***作部材と一体回動し電磁石の通電時に該電磁石に吸着されて非回動状態に固定される構成としてなることを特徴とする。 The present invention includes an operated member that is provided on the apparatus main body so as to be rotatable and is operated by an external operating force, a rotation resistance receiving portion having a substantially V-shaped concave surface portion, a spring, and a pressing member. And a resistance applying means for applying a rotation resistance by pressing the pressing member against the concave surface portion of the rotation resistance receiving portion by the spring force of the spring, and the concave portion on the rotation resistance receiving portion. A pair of rotation restricting portions that are provided on both end sides and abut against and engage with the resistance applying means, an electromagnet provided in the apparatus main body, and a rotation position of the operated member are detected. A rotation position detecting means for controlling the switching of the electromagnet according to the rotation position of the operated member detected by the position detection means, and the rotation resistance receiving portion and the resistance One of the providing means is provided so as to be rotatable integrally with the operated member. On the other hand, and characterized by comprising a structure that is fixed the at-energized said electromagnet is attracted to the electromagnet when the integral rotation electromagnet energized with the operated member in a non-rotating state.

上記構成において、使用者による外部からの操作力によって***作部材を回動操作すると、前記回動抵抗受部と前記抵抗付与手段との一方が、前記***作部材と一体回動し、他方が、前記電磁石の断電時に前記***作部材と一体回動する。従って、電磁石の断電時には、***作部材の回動操作に伴って前記回動抵抗受部と前記抵抗付与手段との両方が回動し、節度は発生しない。そして、***作部材が所定の回動位置に達すると、位置検出手段により当該所定の回動位置が検出され、制御手段により、電磁石が通電される。この通電により、前記回動抵抗受部と前記抵抗付与手段とのうちの他方が、該電磁石に吸着されて非回動状態に固定される。すると、抵抗付与手段の押圧部材がばねのばね力に抗して回動抵抗受部の凹面部を絶対的に（或は相対的に）摺動するようになり、ばねのばね力が増加して抵抗感が強くなる。そして、***作部材が所定の回動位置に達すると、電磁石が断電され、この抵抗感がなくなる。ばねによる抵抗感の急変により節度が発生する。 In the above configuration, when the operated member is rotated by an external operation force by the user, one of the rotation resistance receiving portion and the resistance applying unit rotates integrally with the operated member, and the other is When the electromagnet is turned off, the electromagnet rotates integrally with the operated member. Therefore, when the electromagnet is disconnected, both the turning resistance receiving portion and the resistance applying means are turned in accordance with the turning operation of the operated member, and no moderation occurs. When the operated member reaches a predetermined rotation position, the predetermined rotation position is detected by the position detection means, and the electromagnet is energized by the control means. By this energization, the other of the rotation resistance receiving portion and the resistance applying means is attracted to the electromagnet and fixed in a non-rotation state. Then, the pressing member of the resistance applying means slides absolutely (or relatively) on the concave surface portion of the rotational resistance receiving portion against the spring force of the spring, and the spring force of the spring increases. The resistance becomes stronger. When the operated member reaches a predetermined rotation position, the electromagnet is disconnected and this resistance is lost. Moderation occurs due to a sudden change in resistance caused by the spring.

本発明によれば、前記所定の回動位置の変更により、節度角度を容易に変更できる。また、略Ｖ形の凹面部を有する回動抵抗受部と、ばね及び押圧部材を有し、該ばねのばね力により、前記押圧部材を回動抵抗受部の前記凹面部に対して押圧して回動抵抗を与えるための抵抗付与手段とで、節度を与える構成であるから、ばねの選定と、凹面部の傾斜角度の設定により節度の間隔と強弱の設定が容易となる。 According to the present invention, the moderation angle can be easily changed by changing the predetermined rotation position. Further, the rotating resistance receiving portion having a substantially V-shaped concave surface portion, and a spring and a pressing member, the pressing member is pressed against the concave surface portion of the rotating resistance receiving portion by the spring force of the spring. Since the resistance applying means for applying the rotation resistance provides the moderation, the moderation interval and strength can be easily set by selecting the spring and setting the inclination angle of the concave surface portion.

更に、上記構成によれば、***作部材が所定の回動位置に達した場合に、電磁石の通電を継続すると、上記のように押圧部材が凹面部を摺動した後、抵抗付与手段が回動規制部に当接して係止されるので、***作部材の回動を規制することができる。従って、制御手段による電磁石の通断電制御によって、節度を付与するだけでなく***作部材を所望の回動範囲に規制することができる。 Further, according to the above configuration, when the electromagnet is continuously energized when the operated member reaches the predetermined rotation position, the resistance applying means rotates after the pressing member slides on the concave portion as described above. Since it abuts and is locked by the movement restricting portion, it is possible to restrict the rotation of the operated member. Therefore, not only the moderation is imparted but also the operated member can be restricted to a desired rotation range by the electromagnet switching control of the electromagnet by the control means.

＜第１の実施例＞
以下、本発明を例えば自動車の温度コントロール用スイッチに適用した第１の実施例につき図１ないし図５を参照して説明する。 <First embodiment>
Hereinafter, a first embodiment in which the present invention is applied to, for example, a temperature control switch for an automobile will be described with reference to FIGS.

温度コントロール用スイッチの操作装置（以下、節度装置２０と称す）は、装置本体としての装置ケース２１を備えている。装置ケース２１は、インストルメントパネル２２の裏面側の適宜部位に取り付け固定されている。装置ケース２１の後端部（図では左端部）および前端部には、軸受部２１ａおよび２１ｂが形成されており、これら軸受部２１ａ，２１ｂに、***作部材に相当する軸２３が回動可能に支承されている。この軸２３においてインストルメントパネル２２の表面側に突出する前端部には、ノブ２４が軸２３と一体回動する形態に取り付けられている。図３に示すように、ノブ２４は、正面視にて円形をなし、インストルメントパネル２２の表面に、前記の温度コントロール用であることを示す「ＴＥＭＰ」の文字が印刷表示されている。つまり、温度コントロール用スイッチは、使用者によるノブ２４の回動操作によって、例えば１８℃〜３２℃の温度に設定可能な所謂ロータリスイッチとして構成されている。尚、後述するように、ノブ２４の回動は、図中１８℃〜３２℃で示す目盛りＭの範囲内に規制されるようになっている。 A temperature control switch operating device (hereinafter referred to as a moderation device 20) includes a device case 21 as a device main body. The device case 21 is attached and fixed to an appropriate part on the back side of the instrument panel 22. Bearing portions 21a and 21b are formed at the rear end portion (left end portion in the figure) and the front end portion of the device case 21, and the shaft 23 corresponding to the operated member can be rotated on these bearing portions 21a and 21b. It is supported by. A knob 24 is attached to a front end portion of the shaft 23 that protrudes to the surface side of the instrument panel 22 so as to rotate integrally with the shaft 23. As shown in FIG. 3, the knob 24 has a circular shape when viewed from the front, and characters “TEMP” indicating that it is for temperature control are printed on the surface of the instrument panel 22. That is, the temperature control switch is configured as a so-called rotary switch that can be set to a temperature of, for example, 18 ° C. to 32 ° C. by a turning operation of the knob 24 by the user. As will be described later, the rotation of the knob 24 is regulated within a range of a scale M indicated by 18 ° C. to 32 ° C. in the drawing.

前記軸２３には、後側の軸受部２１ａの近傍部に、回動位置検出手段としての位置センサ２５が軸２３と一体回動する形態に取り付けられている。位置センサ２５は、例えばポテンショメータから構成されており、軸２３（乃至ノブ２４）の回動位置を検出する。 A position sensor 25 as a rotation position detecting means is attached to the shaft 23 in the vicinity of the rear bearing portion 21 a so as to rotate integrally with the shaft 23. The position sensor 25 is composed of a potentiometer, for example, and detects the rotational position of the shaft 23 (or knob 24).

前記装置ケース２１内の電磁石ホルダ２１ａには、略円筒形の電磁石２６が取着されており、この電磁石２６の中空部を軸２３が挿通している。
また、軸２３における電磁石２６の前方には、略円筒状の回動抵抗受部２７が軸２３と一体回動するように設けられている。図２の縦断正面図に示すように、回動抵抗受部２７の中空部は、軸２３と同心の半円部２８と、この半円部２８に連続する菱形部２９とからなり、菱形部２９の外周側の周縁部は、略Ｖ形の凹面部３０とされている。この凹面部３０は、斜面３０ａと斜面３０ｂとで略Ｖ形をなす。他方、菱形部２９の周縁部において半円部２８に連続する部分は、外周側に拡開するハ形（図２中、逆Ｖ形）の回動規制部３１とされている。この回動規制部３１は、斜面３１ａと斜面３１ｂとで略ハ形をなす。 A substantially cylindrical electromagnet 26 is attached to the electromagnet holder 21 a in the device case 21, and a shaft 23 is inserted through the hollow portion of the electromagnet 26.
Further, a substantially cylindrical rotational resistance receiving portion 27 is provided in front of the electromagnet 26 on the shaft 23 so as to rotate integrally with the shaft 23. As shown in the longitudinal sectional front view of FIG. 2, the hollow portion of the rotational resistance receiving portion 27 includes a semicircular portion 28 concentric with the shaft 23 and a rhombus portion 29 continuous with the semicircular portion 28. The peripheral edge portion on the outer peripheral side of 29 is a substantially V-shaped concave surface portion 30. The concave portion 30 is substantially V-shaped with the slope 30a and the slope 30b. On the other hand, a portion continuous with the semicircular portion 28 in the peripheral portion of the rhombus portion 29 is a C-shaped rotation restricting portion 31 (inverse V shape in FIG. 2) that expands to the outer peripheral side. The rotation restricting portion 31 has a substantially C shape with the slope 31a and the slope 31b.

また、この回動抵抗受部２７の内部における軸２３部分には、抵抗付与手段３２が設けられている。抵抗付与手段３２は、鋼線製コイルばね３４、押圧部材３５及びガイド筒部３６を有し、被吸着部材３３に固着されている。
この被吸着部材３３は磁性材からなり、円筒部３３ａと、これの後端部に形成された径大な被吸着部３３ｂとを有した構成である。前記被吸着部３３ｂは、前記電磁石２６の前端面と軸方向で対向している。この被吸着部材３３は、軸２３に回動可能に嵌合されている。 Further, a resistance applying means 32 is provided on the shaft 23 portion inside the rotation resistance receiving portion 27. The resistance applying means 32 includes a steel wire coil spring 34, a pressing member 35, and a guide cylinder portion 36, and is fixed to the attracted member 33.
The attracted member 33 is made of a magnetic material and has a cylindrical portion 33a and a large attracted portion 33b formed at the rear end of the cylindrical portion 33a. The attracted portion 33b faces the front end surface of the electromagnet 26 in the axial direction. The attracted member 33 is rotatably fitted to the shaft 23.

前記ガイド筒部３６は前記被吸着部材３３の円筒部３３ａに遠心方向へ延びるように取着されており、このガイド筒部３６の先端側の内部には前記押圧部材３５を移動可能に収容配置している。更にこのガイド筒部３６の内部には、前記コイルばね３４が圧縮状態で収容配置されており、このコイルばね３４は例えば、ばね用鋼線から構成されたものである。このコイルばね３４のばね力により、図２に示すように、押圧部材３５が前記凹面部３０の谷中心部に押圧付勢されている。 The guide tube portion 36 is attached to the cylindrical portion 33a of the attracted member 33 so as to extend in the centrifugal direction, and the pressing member 35 is movably accommodated in the inside of the distal end side of the guide tube portion 36. is doing. Further, the coil spring 34 is accommodated in a compressed state inside the guide tube portion 36, and the coil spring 34 is made of, for example, a steel wire for spring. Due to the spring force of the coil spring 34, the pressing member 35 is pressed and urged toward the center of the valley of the concave surface portion 30 as shown in FIG. 2.

インストルメントパネル２２の裏面側の適宜部位には、図示しない制御ユニットが設けられており、この制御ユニットに、制御手段としての制御装置３７（図４にのみ図示）が備えられている。制御装置３７は、位置センサ２５から回動位置検出信号を受けて、電磁石２６を所定の回動位置で通電及び断電制御する。また制御ユニットには、手動操作されて前記通断電パターン（所定の回動位置）を任意に設定するための設定部３７ａ（図４参照）が設けられている。つまり、設定部３７ａは、設定手段に相当し、その操作に基づいて前記制御装置３７における電磁石２６に対する通断電パターンを変更可能としており、後述するクリック感（或はバリヤ感）が付与される位置や間隔、幅などを自由に設定することができるように構成されている。 A control unit (not shown) is provided at an appropriate portion on the back side of the instrument panel 22, and this control unit is provided with a control device 37 (shown only in FIG. 4) as control means. The control device 37 receives the rotation position detection signal from the position sensor 25, and controls energization and disconnection of the electromagnet 26 at a predetermined rotation position. Further, the control unit is provided with a setting unit 37a (see FIG. 4) that is manually operated to arbitrarily set the power interruption pattern (predetermined rotation position). That is, the setting unit 37a corresponds to setting means, and can change a power interruption pattern with respect to the electromagnet 26 in the control device 37 based on the operation thereof, and a click feeling (or a barrier feeling) described later is given. The position, interval, width, etc. can be set freely.

この場合、所定の回動位置は、前記設定温度の目盛りＭに対応しており、例えば目盛りＭのピッチ角Ａ°（図５参照）で通電及び断電が行われるように設定されている。詳細には、ノブ２４の操作により軸２３が回動される際に、図５に示すようにピッチ角Ａ°ごとに角度範囲ａ１°の領域で通電され、角度範囲ａ２°の領域で断電される。また、目盛りＭの範囲外の領域である、下限目盛り点Ｐｃ未満の領域および上限目盛り点Ｐｈを超える領域についても通電される。 In this case, the predetermined rotation position corresponds to the scale M of the set temperature, and is set such that energization and disconnection are performed at a pitch angle A ° (see FIG. 5) of the scale M, for example. Specifically, when the shaft 23 is rotated by the operation of the knob 24, as shown in FIG. 5, current is supplied in the range of the angle range a1 ° for each pitch angle A °, and power is cut off in the range of the angle range a2 °. Is done. In addition, energization is also performed in a region outside the range of the scale M, that is, a region below the lower limit scale point Pc and a region beyond the upper limit scale point Ph.

図１及び図２の状態では、電磁石２６が断電されている状態を示しており、この状態では、押圧部材３５は、回動抵抗受部２７の凹面部３０の谷中心部に押圧付勢されており、前記被吸着部材３３が軸２３に対して回動可能である。この場合、図３に示すように、軸２３（ノブ２４）は設定温度が２４℃となる回動位置にある。 1 and 2 show a state in which the electromagnet 26 is disconnected. In this state, the pressing member 35 presses and urges the valley center portion of the concave surface portion 30 of the rotation resistance receiving portion 27. The attracted member 33 is rotatable with respect to the shaft 23. In this case, as shown in FIG. 3, the shaft 23 (knob 24) is in a rotational position where the set temperature is 24 ° C.

この状態から、使用者が設定温度を下げるべくノブ２４を矢印Ｄ１方向（図２、図３参照）に回動操作すると、軸２３、回動抵抗受部２７、位置センサ２５が一体回動する。このとき、上述したように、押圧部材３５が回動抵抗受部２７の凹面部３０の谷中心部に押圧付勢され、且つ被吸着部材３３が軸２３に対して回動可能であるから、押圧部材３５も一体回動する。つまり、電磁石２６の断電時には、ノブ２４の回動操作に伴って前記回動抵抗受部２７と前記抵抗付与手段２７との両方が回動し、節度は発生しない。 From this state, when the user rotates the knob 24 in the direction of arrow D1 (see FIGS. 2 and 3) to lower the set temperature, the shaft 23, the rotation resistance receiving portion 27, and the position sensor 25 rotate integrally. . At this time, as described above, the pressing member 35 is pressed and urged to the central portion of the valley of the concave surface portion 30 of the rotation resistance receiving portion 27, and the attracted member 33 can rotate with respect to the shaft 23. The pressing member 35 also rotates integrally. That is, when the electromagnet 26 is disconnected, both the turning resistance receiving portion 27 and the resistance applying means 27 are turned along with the turning operation of the knob 24, and no moderation occurs.

制御装置３７は、位置センサ２５からの信号によって、軸２３の回動位置を検出し、角度範囲ａ１°の領域で電磁石２６を通電する（図５参照）。この通電により電磁石２６が被吸着部材３３において対向する被吸着部３３ｂを吸着固定もしくは吸引固定する。 The control device 37 detects the rotational position of the shaft 23 based on a signal from the position sensor 25, and energizes the electromagnet 26 in the angular range a1 ° (see FIG. 5). By this energization, the electromagnet 26 attracts or attracts and fixes the attracted portion 33 b facing the attracted member 33.

これにより押圧部材３５が回動不能状態に固定され、回動抵抗受部２７は、引き続き使用者による回動操作力を受けて矢印Ａ方向へ回動される。このときに、該回動抵抗受部２７の凹面部３０の斜面３０ａが押圧部材３５と摺接し、押圧方向へのコイルばね３４のばね力により、該回動抵抗受部２７が回動抵抗を使用者が感じるようになる。（図５（ｂ）参照）。制御装置３７は、この電磁石２６に対する通電を、角度範囲ａ１°からａ２°領域側へ回動したことを検出するまで行い、断電する。この断電により、押圧部材３５は、斜面３０ａの谷中心部へ戻り、回動抵抗がなくなる。このときに節度（クリック感）が与えられる。この断電は、角度範囲ａ２°からａ１°領域側へ回動したことを検出するまで行われる。 As a result, the pressing member 35 is fixed in a non-rotatable state, and the rotation resistance receiving portion 27 continues to rotate in the arrow A direction in response to the rotation operation force by the user. At this time, the inclined surface 30a of the concave surface portion 30 of the rotational resistance receiving portion 27 is in sliding contact with the pressing member 35, and the rotational resistance receiving portion 27 reduces the rotational resistance by the spring force of the coil spring 34 in the pressing direction. The user feels it. (See FIG. 5 (b)). The control device 37 energizes the electromagnet 26 until it is detected that the electromagnet 26 is rotated from the angle range a1 ° to the a2 ° region side, and the power is cut off. Due to this disconnection, the pressing member 35 returns to the center of the valley of the inclined surface 30a, and there is no rotational resistance. Moderation (click feeling) is given at this time. This disconnection is performed until it is detected that the angle range a2 ° is turned to the a1 ° region side.

こうして、ノブ２４の矢印Ｄ１方向への回動操作に伴い、設定温度が１℃変化するたびに使用者に節度が付与される。そして、軸２３が下限目盛り点Ｐｃを超えて矢印Ｄ１方向へ回動されると、制御装置３７は電磁石２６を通電する。この通電では、前述のように押圧部材３５が回動不能状態に固定され凹面部３０の斜面３０ａが押圧部材３５と摺接するだけでなく、回動規制部３１の斜面３１ａが抵抗付与手段３２のガイド筒部３６に対し当接して軸２３を係止するようになっている。つまり、下限目盛り点Ｐｃ未満の領域において、通電される角度範囲ａ０°（図５参照）は、通電を開始してから回動規制部３１の斜面３１ａとガイド筒部３６が当接するまでの回動角度ｂ１°（図２参照）よりも大きく設定されている（ａ０°＞ｂ１°）。このため、軸２３が下限目盛り点Ｐｃを超えて、引き続き使用者による矢印Ｄ１方向へ回動操作力を受けると、回動規制部３１の斜面３１ａとガイド筒部３６が当接した際に使用者が大きな回動抵抗（所謂バリア感）を感じる。ここで、使用者が回動操作力を解除すると、回動抵抗受部２７はコイルばね３４のばね力により、凹面部３０の谷中心部が押圧部材３５へ向かうように矢印Ｄ２方向へ回動する。そして、制御装置３７は、下限目盛り点Ｐｃの回動位置を検出した時点で断電すると共に、押圧部材３５が凹面部３０の谷中心部に押圧付勢された状態となる。 Thus, a moderation is given to the user every time the set temperature changes by 1 ° C. in accordance with the turning operation of the knob 24 in the arrow D1 direction. When the shaft 23 is rotated in the direction of the arrow D1 beyond the lower limit scale point Pc, the control device 37 energizes the electromagnet 26. In this energization, as described above, the pressing member 35 is fixed in a non-rotatable state and the inclined surface 30 a of the concave surface portion 30 is in sliding contact with the pressing member 35, and the inclined surface 31 a of the rotation restricting portion 31 is The shaft 23 is locked by coming into contact with the guide tube portion 36. In other words, in the area below the lower limit scale point Pc, the energized angle range a0 ° (see FIG. 5) is the rotation from the start of energization until the inclined surface 31a of the rotation restricting portion 31 and the guide cylinder portion 36 come into contact. The moving angle is set to be larger than b1 ° (see FIG. 2) (a0 °> b1 °). Therefore, when the shaft 23 exceeds the lower limit scale point Pc and subsequently receives a turning operation force in the direction of the arrow D1 by the user, it is used when the inclined surface 31a of the turning restricting portion 31 and the guide tube portion 36 come into contact with each other. People feel a large turning resistance (so-called barrier feeling). Here, when the user releases the rotation operation force, the rotation resistance receiving portion 27 is rotated in the direction of the arrow D2 by the spring force of the coil spring 34 so that the valley center portion of the concave surface portion 30 is directed to the pressing member 35. To do. And the control apparatus 37 will be in the state by which the press member 35 was pressed and urged | biased by the trough center part of the concave surface part 30 while detecting the turning position of the lower limit scale point Pc.

尚、詳細な説明は省略するが、軸２３が上限目盛り点Ｐｈを超えて矢印Ｄ２方向へ回動操作された場合、通電される角度範囲ａ３°は、通電を開始してから回動規制部３１の斜面３１ｂとガイド筒部３６が当接するまでの回動角度ｂ２°よりも大きく設定されている（ａ３°＞ｂ２°）。これにより、ノブ２４の回動操作を目盛りＭの範囲内に規制することができる。 Although detailed explanation is omitted, when the shaft 23 is rotated in the direction of the arrow D2 beyond the upper limit scale Ph, the angle range a3 ° to be energized is the rotation restricting portion after the energization is started. 31 is set to be larger than a rotation angle b2 ° until the inclined surface 31b of the guide 31 comes into contact with the guide tube portion 36 (a3 °> b2 °). Thereby, the turning operation of the knob 24 can be restricted within the range of the scale M.

このように本実施例によれば、凹面部３０の両端部側に一対の回動規制部３１を設け、抵抗付与手段３２に対し当接して係止するように構成したので、***作部材たる軸２３を所望の回動範囲に規制することができる。従って、設定部３７ａにより通断電パターンを変更することで軸２３を任意の回動範囲に規制することができ、様々なロータリスイッチや適宜の操作対象物に適用することができる。 As described above, according to the present embodiment, the pair of rotation restricting portions 31 are provided on both end sides of the concave surface portion 30 and are configured to contact and lock against the resistance applying means 32. The shaft 23 can be restricted to a desired rotation range. Therefore, the shaft 23 can be restricted to an arbitrary rotation range by changing the power interruption pattern by the setting unit 37a, and can be applied to various rotary switches and appropriate operation objects.

本実施例とは異なり、軸２３（ノブ２４）を所定の回動位置で停止させるには、例えばインストルメントパネル２２に、ノブ２４の回動を規制するための係止部を設ける必要がある。これに対し、節度装置２０によれば、回動規制部３１が回動抵抗受部２７の内周面を利用して形成されているので、部品点数を増加させることなく軸２３の回動範囲を規制することができる。また、回動規制部３１は回動抵抗受部２７に対し直接当接して係止する構成であるので、大きな回動抵抗を得ることができる。 Unlike this embodiment, in order to stop the shaft 23 (knob 24) at a predetermined rotation position, for example, the instrument panel 22 needs to be provided with a locking portion for restricting the rotation of the knob 24. . On the other hand, according to the moderation device 20, since the rotation restricting portion 31 is formed using the inner peripheral surface of the rotation resistance receiving portion 27, the rotation range of the shaft 23 without increasing the number of parts. Can be regulated. In addition, since the rotation restricting portion 31 is configured to directly contact and lock against the rotation resistance receiving portion 27, a large rotation resistance can be obtained.

また、電磁石２６を通電及び断電するタイミングである前記所定の回動位置の変更により、節度角度を容易に変更できる。また、コイルばね３４と凹面部３０の傾斜角度の設定により節度の強弱や間隔の設定が容易となり、所望の回動抵抗を得ることができる。 In addition, the moderation angle can be easily changed by changing the predetermined rotation position, which is the timing when the electromagnet 26 is energized and disconnected. Further, the setting of the inclination angle of the coil spring 34 and the concave surface portion 30 makes it easy to set the strength of the moderation and the interval, and a desired rotation resistance can be obtained.

更に、本実施例によれば、使用者によって操作される設定部３７ａを備え、制御装置３７が、該設定部３７ａの操作に基づいて、前記電磁石２６に対する通断電パターンを変更するから、節度角度を任意且つ容易に変更できて、利便性に優れている。つまり、前述したピッチ角Ａ°、角度範囲ａ１°角度範囲ａ２°、下限目盛り点Ｐｃ及び上限目盛り点Ｐｈは一例にすぎず、設定部３７ａの操作によって通電領域と断電領域を自由に設定することができる。従って、上記構成の節度装置２０によれば、任意の位置で前記のバリヤ感とクリック感とを実現することができると共に、その位置の設定および変更も容易に行うことができる。 Furthermore, according to the present embodiment, the setting unit 37a operated by the user is provided, and the control device 37 changes the power interruption pattern for the electromagnet 26 based on the operation of the setting unit 37a. The angle can be changed arbitrarily and easily, and it is excellent in convenience. That is, the pitch angle A °, the angle range a1 °, the angle range a2 °, the lower limit scale point Pc, and the upper limit scale point Ph described above are merely examples, and the energization region and the disconnection region are freely set by operating the setting unit 37a. be able to. Therefore, according to the moderation device 20 configured as described above, the barrier feeling and the click feeling can be realized at an arbitrary position, and the setting and changing of the position can be easily performed.

＜第２の実施例＞
図６、図７は本発明の第２の実施例を示すものであり、第１の実施例と異なるところを説明する。尚、第１の実施例と同一部分には同一符号を付している。
軸２３には、電磁石２６と軸受部２１ｂとの間に、径大な円筒部３８が形成されている。抵抗付与手段３２は、この円筒部３８の内周面に、中心へ向かうように固着されることにより、ノブ２４と一体回動可能に配設されている。 <Second Embodiment>
6 and 7 show a second embodiment of the present invention, and different points from the first embodiment will be described. The same parts as those in the first embodiment are denoted by the same reference numerals.
On the shaft 23, a large-diameter cylindrical portion 38 is formed between the electromagnet 26 and the bearing portion 21b. The resistance applying means 32 is disposed on the inner peripheral surface of the cylindrical portion 38 so as to be directed toward the center, so that the resistance applying means 32 can be integrally rotated with the knob 24.

被吸着部材３３に代わる被吸着部材３９は、被吸着部３３ｂと回動抵抗受部４０とを一体に有して構成されている。回動抵抗受部４０は、図７の縦断正面図に示すように、全体として肉厚な円筒状をなし、その外周部（図中、下側部）には、外周側が拡開する略Ｖ形の凹面部４１が形成されている。凹面部４１は、斜面４１ａと斜面４１ｂとで略Ｖ形をなす。他方、凹面部４１の両端部側には、抵抗付与手段３２のガイド筒部３６に対し当接して係止する一対の凸部（回動規制部に相当する）４２ａ，４２ｂが形成されている。 A member to be attracted 39 that replaces the member to be attracted 33 is configured by integrally including a portion to be attracted 33 b and a rotation resistance receiving portion 40. As shown in the longitudinal front view of FIG. 7, the rotation resistance receiving portion 40 has a thick cylindrical shape as a whole, and its outer peripheral portion (the lower portion in the figure) has a substantially V shape in which the outer peripheral side expands. A concave portion 41 having a shape is formed. The concave surface portion 41 is substantially V-shaped with the slope 41a and the slope 41b. On the other hand, a pair of convex portions (corresponding to a rotation restricting portion) 42a and 42b are formed on both end sides of the concave surface portion 41 so as to abut against and engage with the guide tube portion 36 of the resistance applying means 32. .

上記構成によれば、回動抵抗受部４０は、電磁石２６の断電時にノブ２４と一体回動し、電磁石２６の通電時に該電磁石２６に吸着されて非回動状態に固定されため、第１の実施例と同様の効果を得ることができる。 According to the above configuration, the rotation resistance receiving portion 40 rotates integrally with the knob 24 when the electromagnet 26 is disconnected, and is attracted to the electromagnet 26 when the electromagnet 26 is energized and fixed in a non-rotating state. The same effect as that of the first embodiment can be obtained.

尚、回動位置検出手段としては、ポテンショメータに限られず、ロータリーエンコーダや、複数のホールＩＣと磁極との組み合わせ構成でもよい。押圧部材は球状に形成しても良いし、鋼球を用いてもよい。また、電磁石２６の通電と断電の角度範囲は前述したａ１°やａ２°等に限るものではなく、任意に設定することができる。 The rotation position detection means is not limited to a potentiometer, and may be a rotary encoder or a combination of a plurality of Hall ICs and magnetic poles. The pressing member may be formed in a spherical shape, or a steel ball may be used. Further, the angle range between energization and disconnection of the electromagnet 26 is not limited to the above-described a1 °, a2 °, etc., and can be arbitrarily set.

回動規制部は、上記構成に限定するものではなく、抵抗付与手段３２の少なくとも一部に対し当接して係止するよう凹面部の両端部側に設けられたものであればよい。
凹面部３０は全体として略Ｖ形であればよく、その谷中心部の形状は、図示した角部に限定するものではない。例えば凹面部３０の谷中心部は丸みを帯びていてもよいし、狭小な平坦部であってもよい。 The rotation restricting portion is not limited to the above configuration, and may be any portion provided on both end sides of the concave surface portion so as to abut against and be locked to at least a part of the resistance applying means 32.
The concave portion 30 may be substantially V-shaped as a whole, and the shape of the central portion of the valley is not limited to the illustrated corner. For example, the central part of the valley of the concave surface part 30 may be rounded or a narrow flat part.

また、本発明は、ロータリスイッチ以外の各種の操作対象物にも適用できるものである。例えば、ジョイスティック装置において、使用者により操作されるジョイスティック部材によって、節度装置２０の軸２３が回動操作されるように構成してもよい。これにより、ジョイスティック部材の回動に対し節度を付与することができると共に、その回動範囲を規制することができる。 The present invention can also be applied to various operation objects other than the rotary switch. For example, in the joystick device, the shaft 23 of the moderation device 20 may be rotated by a joystick member operated by a user. Thereby, moderation can be given to the rotation of the joystick member, and the rotation range can be restricted.
