Description

この発明は押圧操作部に係わり、特に、その保持構造に関する。   The present invention relates to a pressing operation portion, and more particularly to a holding structure thereof.

従来から音響機器、ビデオ再生装置等の電子機器において、操作パネルに傾動自在に支持され傾動させることにより2つのスイッチを択一的に作動させるシーソつまみが使用されている。そのようなシーソつまみの保持構造の例を図5〜図7により説明する。   2. Description of the Related Art Conventionally, in an electronic device such as an audio device or a video playback device, a seesaw knob that selectively supports two switches by being tilted and supported by an operation panel has been used. Examples of such a seesaw knob holding structure will be described with reference to FIGS.

図6(a)および(b)に示すシーソつまみ5は図5に示すように、操作パネル6の穴6aに入り込むように配置され、その軸5aが操作パネル6の凹部6bに嵌合して軸5a回りに回動自在に支持される。なお、シーソつまみ5が操作パネル6から抜けないように係止するための抜け止め防止部材は図示していない。   As shown in FIG. 5, the seesaw knob 5 shown in FIGS. 6A and 6B is disposed so as to enter the hole 6a of the operation panel 6, and its shaft 5a is fitted into the recess 6b of the operation panel 6. It is supported so as to be rotatable around the shaft 5a. It should be noted that a retainer prevention member for locking the seesaw knob 5 so as not to be detached from the operation panel 6 is not shown.

シーソつまみ5の下面両側に設けられたボス5b、5bは操作パネル6の下側に固定されたプリント基板3に実装されたスイッチ4、4と対向している。通常シーソつまみ5はスイッチ4、4の作動子に加えられた弾力または操作パネル6等に設けられたヒンジの弾力により中立位置にあり、スイッチ4、4は作動していない。   The bosses 5b and 5b provided on both sides of the bottom surface of the seesaw knob 5 are opposed to the switches 4 and 4 mounted on the printed circuit board 3 fixed to the lower side of the operation panel 6. Usually, the seesaw knob 5 is in a neutral position by the elasticity applied to the actuators of the switches 4 and 4 or the elasticity of the hinge provided on the operation panel 6 and the like, and the switches 4 and 4 are not operated.

シーソつまみ5の一方の側を指で押すとシーソつまみ5が傾動してスイッチ4、4の一方を作動させる。図7にシーソつまみ5を矢印方向に押して傾動させた状態を模式的に示している。図7には、軸5aからスイッチ4の作動点までの操作パネル面方向の距離をLで示し、シーソつまみ5の傾動角度をθで示している。傾動角度をθが大きくなるとボス5bが傾き、スイッチ4を斜め方向から押すことになる。   When one side of the seesaw knob 5 is pressed with a finger, the seesaw knob 5 is tilted to activate one of the switches 4 and 4. FIG. 7 schematically shows a state where the seesaw knob 5 is pushed and tilted in the arrow direction. In FIG. 7, the distance in the operation panel surface direction from the shaft 5 a to the operating point of the switch 4 is indicated by L, and the tilt angle of the seesaw knob 5 is indicated by θ. As the tilt angle θ increases, the boss 5b tilts and the switch 4 is pushed from an oblique direction.

この場合スイッチ4がスムーズに動作せず、(a)シーソつまみ5を操作する感触が悪くなるという問題があった。また、(b)ボス5bが斜めに動くため、スイッチ4の作動子から脱落して横方向の力を受けて元に戻らなくなる恐れがある。さらに、(c)シーソつまみ5が操作パネル6から抜けないように係止するための抜け止め防止部材が必要となり、部品点数および組み立て工数が増大するという問題があった。   In this case, there is a problem that the switch 4 does not operate smoothly, and (a) the feel of operating the seesaw knob 5 is deteriorated. Further, (b) since the boss 5b moves obliquely, it may fall off from the actuator of the switch 4 and may not return to its original state due to a lateral force. Further, (c) a retaining member for securing the seesaw knob 5 so as not to be detached from the operation panel 6 is required, which increases the number of parts and the number of assembly steps.

この発明は上記した点に鑑みてなされたものであって、その目的とするところは、押圧操作部を操作する感触がよく、また、スイッチを作動させるボスがスイッチの作動子から脱落する恐れがない押圧操作部の保持構造を提供することにある。   The present invention has been made in view of the above points, and the object of the present invention is to provide a good feeling to operate the pressing operation unit, and there is a risk that the boss that operates the switch may fall off from the switch actuator. There is no need to provide a holding structure for the pressing operation unit.

また、この発明の他の目的は、部品点数および組み立て工数が少ない押圧操作部の保持構造を提供することである。   Another object of the present invention is to provide a holding structure for a pressing operation portion with a small number of parts and assembly man-hours.

この発明の押圧操作部の保持構造は、両側の一方の側が他方の側に対して操作パネル前面より沈み込むように双方向傾動自在に操作パネルに保持され、押圧操作により傾動され背後に配置された一対のスイッチの一方の側のスイッチを作動させる押圧操作部の保持構造において、前記押圧操作部の両側の背後に前記傾動の回動軸となる軸を夫々設け、前記2つの軸を前記操作パネルに設けたリブとその背後に設けたヒンジで挟み込むように支持したものである。 The holding structure of the pressing operation portion according to the present invention is held by the operation panel so as to be bi-directionally tiltable so that one side of both sides sinks from the front of the operation panel with respect to the other side, and is tilted by the pressing operation and disposed behind. In the holding structure of the pressing operation unit that operates the switch on one side of the pair of switches, an axis that serves as the rotation axis of the tilt is provided behind both sides of the pressing operation unit, and the two axes are operated It is supported so as to be sandwiched between a rib provided on the panel and a hinge provided behind the rib.

また、前記押圧操作部の保持構造において、前記押圧操作部の夫々の軸が前記操作パネルのリブおよびヒンジを弾性変形させて前記挟み込まれる位置に押し込まれたものである。   Further, in the holding structure of the pressing operation unit, the respective shafts of the pressing operation unit are pushed into the sandwiched positions by elastically deforming the ribs and hinges of the operation panel.

この発明の押圧操作部の保持構造によれば、スイッチを作動させるための押圧操作部の傾動角が小さくなるので、スイッチを押圧操作部のボスが傾斜することなくスムーズに動作させることができ、また、押圧操作部が押圧操作部に設けた軸回りに回動するので摩擦抵抗が小さく押圧操作部を操作する感触が良い。   According to the holding structure of the pressing operation portion of the present invention, since the tilt angle of the pressing operation portion for operating the switch becomes small, the switch can be operated smoothly without the boss of the pressing operation portion being inclined, In addition, since the pressing operation unit rotates about the axis provided in the pressing operation unit, the frictional resistance is small, and the feeling of operating the pressing operation unit is good.

さらに、押圧操作部のボスがスイッチの作動子から脱落して横方向の力を受けて元に戻らなくなることがない。   Furthermore, the boss of the pressing operation unit does not fall off from the switch actuator and receive the lateral force and cannot be restored.

以下この発明を実施するための最良の形態を実施例に即して説明する。図1は、この発明の実施例である押圧操作部の保持構造を一部部材を除いて示す側面図、図2は同押圧操作部の保持構造に用いられる押圧操作部を裏側から見た斜視図、図3は図1における一部部材を除いて示すA−A断面図である。   The best mode for carrying out the present invention will be described below with reference to examples. FIG. 1 is a side view showing a holding structure of a pressing operation unit according to an embodiment of the present invention, excluding some members, and FIG. 2 is a perspective view of the pressing operation unit used in the holding structure of the pressing operation unit seen from the back side. FIG. 3 is a cross-sectional view taken along the line AA, excluding some members in FIG.

図1および図2に示す押圧操作部1は図1に示すように、操作パネル2の穴2cに入り込むように配置され、その軸1a、1a…が操作パネル2のリブ2a、2a…とヒンジ2b、2b…との間に挟み込まれて支持される。   As shown in FIG. 1, the pressing operation unit 1 shown in FIGS. 1 and 2 is arranged so as to enter the hole 2 c of the operation panel 2, and its shafts 1 a, 1 a... Are hinged with the ribs 2 a, 2 a. 2b, 2b, etc. are sandwiched and supported.

なお、押圧操作部1は操作パネル2の穴2cの上から押し込まれ、操作パネル2に設けられたリブ2a、2a…とヒンジ2b、2b…を変形させてその間に軸1a、1a…が入り込む。そして、軸1a、1a…は図3に示すヒンジ2b、2b…の位置決め突起2B、2B…により操作パネル2の前面に沿う方向の位置決めがなされる。   The pressing operation unit 1 is pushed in from above the hole 2c of the operation panel 2, and deforms the ribs 2a, 2a ... and the hinges 2b, 2b ... provided on the operation panel 2, and the shafts 1a, 1a ... enter between them. . The shafts 1a, 1a, ... are positioned in the direction along the front surface of the operation panel 2 by positioning projections 2B, 2B, ... of the hinges 2b, 2b, ... shown in FIG.

押圧操作部1の下面両側に設けられたボス1b、1bは操作パネル2の下側に固定されたプリント基板3に実装されたスイッチ4、4と対向している。通常押圧操作部1はヒンジ2b、2b…の弾力により中立位置にあり、スイッチ4、4は作動していない。   The bosses 1b and 1b provided on both sides of the lower surface of the pressing operation unit 1 are opposed to the switches 4 and 4 mounted on the printed circuit board 3 fixed to the lower side of the operation panel 2. The normal pressing operation unit 1 is in a neutral position due to the elasticity of the hinges 2b, 2b... And the switches 4 and 4 are not operated.

押圧操作部1の一方の側を指で押すと押圧操作部1は押した側のヒンジ2bに大きい荷重が加わり弾性変形するが、他方の側のヒンジ2bに殆ど荷重が加わらず変形しないのでそのヒンジ2bに支えられた軸1a回りに押圧操作部1が傾動する。そして、スイッチ4、4の一方を作動させる。   When one side of the pressing operation unit 1 is pressed with a finger, the pressing operation unit 1 is elastically deformed by applying a large load to the hinge 2b on the pressed side. The pressing operation unit 1 tilts around the shaft 1a supported by the hinge 2b. Then, one of the switches 4 and 4 is operated.

図4に押圧操作部1を矢印方向に押して傾動させた状態を模式的に示している。押圧操作部1の大きさが図7で説明した従来の押圧操作部5と同じであり、スイッチ4を作動させるために必要なボス1bのストロークが同じであると、図4に示すように、軸1aからスイッチ4の作動点までの操作パネル面方向の距離は2Lとなり、押圧操作部1の傾動角度は1/2θとなる。すなわち、押圧操作部1の傾動角は図5で説明した従来の押圧操作部5の傾動角の1/2となる。   FIG. 4 schematically shows a state in which the pressing operation unit 1 is pushed and tilted in the arrow direction. If the size of the pressing operation unit 1 is the same as that of the conventional pressing operation unit 5 described in FIG. 7 and the stroke of the boss 1b necessary for operating the switch 4 is the same, as shown in FIG. The distance in the operation panel surface direction from the shaft 1a to the operating point of the switch 4 is 2L, and the tilt angle of the pressing operation unit 1 is 1 / 2θ. That is, the tilting angle of the pressing operation unit 1 is ½ of the tilting angle of the conventional pressing operation unit 5 described in FIG.

このように、スイッチ4を作動させるための押圧操作部1の傾動角が小さくなるので、スイッチ4をボス1bが傾斜することなくスムーズに動作させることができ、また、押圧操作部1が軸1a回りに回動するので摩擦抵抗が小さく押圧操作部1を操作する感触が良い。   Thus, since the tilt angle of the pressing operation unit 1 for operating the switch 4 is reduced, the switch 4 can be operated smoothly without the boss 1b being inclined, and the pressing operation unit 1 is connected to the shaft 1a. Since it rotates around, the frictional resistance is small, and the feeling of operating the pressing operation unit 1 is good.

また、ボス1bがスイッチ4の作動子から脱落して横方向の力を受けて元に戻らなくなることがない。さらに、この実施例では押圧操作部1が操作パネル2から抜けないように係止するための抜け止め防止部材が必要でなく、部品点数が少なくなり押圧操作部1を押し込むだけで操作パネル2に組み付けることができるので組み立て工数が少なくなる。   Further, the boss 1b does not fall off from the actuator of the switch 4 and does not return to its original state due to a lateral force. Further, in this embodiment, there is no need for a retaining member for preventing the pressing operation unit 1 from being detached from the operation panel 2, and the number of parts is reduced, and the operation panel 2 can be simply pushed into the operation panel 2. Since it can be assembled, the number of assembly steps is reduced.

実施例は以上のように構成されているが発明はこれに限られず、例えば、抜け止め防止部材を用いてもこの発明の効果を有する。   The embodiment is configured as described above, but the invention is not limited thereto. For example, even if a retaining member is used, the effect of the invention is obtained.
