Description

【０００１】
【発明の属する技術分野】
本発明はライト付耳かきに関する。
【０００２】
【従来の技術】
従来、耳かき部を耳穴に挿入して使用する場合に、耳穴の内部を照らすライトを備えたライト付耳かきが知られており、その構造として、耳かきの把手部内に棒状の乾電池を収納し、この棒状の乾電池を電源として豆電球を点燈するようにしたものが、例えば実開平７−２８４９７号公報や実登第３０１２６０５号公報に開示されている。
【０００３】
【発明が解決しようとする課題】
今日、偏平な円盤状のコイン型電池が普及し、このコイン型電池は前記棒状の乾電池に比べて小型、軽量であるため、前記のようなライト付耳かきの電源としてコイン型電池を使用すると、そのライト付耳かきの小型、軽量化を図ることができる。
【０００４】
しかし、前記コイン型電池は、全体が円盤状であり、かつその表裏面に電極を有することから、前記従来のライト付耳かきに使用されているスイッチ構造は適用できない。
【０００５】
そこで本発明は、コイン型電池を使用するとともに、そのコイン型電池の使用に適するスイッチ構造を有するライト付耳かきを提案することを目的とするものである。
【０００６】
【課題を解決するための手段】
本発明は前記の課題を解決するために、耳かき棒の基部に電池収納部を設け、先部に耳かき部を設け、少なくとも前記耳かき棒と耳かき部を透光性材料で形成し、前記電池収納部内にはコイン型電池を収納し、前記耳かき棒の基部には発光ダイオードを収納してその光が耳かき棒内に入射されるようにするとともにその発光ダイオードの一方のリード線を前記コイン型電池の一方の極に接触させ、他方のリード線をコイン型電池の他方の極に離間して配置し、更に、電池収納部の外周壁を前記コイン型電池の外周に沿った略円形に形成し、該電池収納部の底板の外面には、該底板部に回転中心を有するスイッチ操作レバーを回動可能に設けるとともに該スイッチ操作レバーの先部を前記電池収納部の外周壁の外面へ折曲して操作部とし、更に前記スイッチ操作レバーには電池収納部内へ突入するスイッチ部を形成し、スイッチ操作レバーの正逆回動によりそのスイッチ部が前記発光ダイオードの他端のリード線をコイン型電池の極へ接離するようにしたことを特徴とするものである。
【０００７】
【発明の実施の形態】
図に示す実施例に基づいて本発明の実施の形態について説明する。
【０００８】
ライト付耳かき１は本体部２とカバー３とからなる。本体部２は、電池収納部４と、該部４より突設した耳かき棒５と、該耳かき棒５の先端に形成した耳かき部６とからなり、これらは透光性材料、例えば透明樹脂で一体に成形されている。なお、耳かき棒５と耳かき部６のみ透過性材料、例えば透明樹脂で形成してもよい。
【０００９】
前記電池収納部４は、前記耳かき棒５の略軸芯より下半部において、上面が開口した凹状に形成され、その内部に環状の電池支板７を立設して、該電池支板７の上面に偏平で円盤状のコイン型電池８が載置収納されている。電池収納部４と耳かき棒５との境には、照明燈である発光ダイオード９を収納する上面が開口した収納部１０が形成され、該収納部１０に発光ダイオード９が、その発光側を耳かき棒５側に向け、一方のリード線１１を前記収納したコイン型電池８の−極８ａ側に接触させ、他方のリード線１２をコイン型電池８の＋極８ｂ側に、その極面から若干離間するようにして突出させて配置されている。該両リード線１１，１２は図４及び図６に示すように、前記コイン型電池８の側方へ屈曲しているとともに、更に先部１１ａ，１２ａがコイン型電池８の略半径方向に向くように折曲されている。
【００１０】
前記電池収納部４の外周壁１３は前記コイン型電池８の外周に沿った略円形、図の例では楕円形（玉子形）の環状に形成されている。該電池収納部４の底板１４の外面にはスイッチ操作レバー１５が備えられている。該スイッチ操作レバー１５は、図３に示すように、これに一体に形成したピン１６を前記底板１４に回転可能に連結して、該ピン１６を中心として回動するように備えられている。
【００１１】
更に、スイッチ操作レバー１５の他端は前記外周壁１３の外周面側へ折曲され、該折曲部が操作部１７になっている。該操作部１７は、その回動方向に対し、ピン１６を中心とする円弧状に形成されている。また、この操作部１７の回動範囲における前記外周壁１３は、操作部１７の前記円弧に沿った曲壁に形成されている。したがって、操作部１７は電池収納部４の外周壁１３の外面に沿って回動する。
【００１２】
なお、図の例ではスイッチ操作レバー１５の回軸中心であるピン１６の位置は、電池収納部４の中心に対して図のように偏芯しているが、電池収納部４の中心でもよい。また、前記操作部１７の外面には指掛け用の凹凸面１８と突起１９が一体形成されている。
【００１３】
更に、前記スイッチ操作レバー１５には、前記電池収納部４の底板１４に形成した長穴状の窓２０から収納室内へ突入するスイッチ部２１が一体形成されている。該スイッチ部２１は、前記コイン型電池８の他方のリード線１２における先部１２ａの下側に係合する位置に設けられているとともに、該スイッチ部２１の上面が回動方向において、オン方向が下降する傾斜面２１ａに形成されており、図６及び図７に示すオン方向Ａに回動すると、前記他方のリード線１２の先部１２ａが傾斜面２１ａによって押し上げられてコイン型電池８の＋極８ｂに接触して前記発光ダイオード９が点燈し、オフ方向Ｂに回動すると、他方のリード線１２の先部１２ａが、その弾性復帰力によってコイン型電池８の＋極８ｂから離間して発光ダイオード９が消燈するようになっている。
【００１４】
前記電池収納部４の底板１４に形成した窓２０における長手方向の一端は、図５に示すように、前記スイッチ部２１のオン方向への回動位置を規制するストッパー２２に形成され、他端はオフ方向への回動位置を規制するストッパー２３になっている。更に、前記発光ダイオード９の他方のリード線１２は、図４に示す前記電池支板７と壁２４で形成された溝２５に嵌って支持されるようになっており、該リード線１２を前記スイッチ部２１でオン方向Ａへ押した場合に、該リード線１２がＡ方向へ逃げることなく上方へ移動して良好なオン作動が行われるようになっている。
【００１５】
更に、図５に示すように、前記操作部１７の内面には係止突部２６が形成され、前記外周壁１３の外面にはオン側凹部２７とオフ側凹部２８が形成されており、操作部１７のオン位置において係止突部２６がオン側凹部２７に嵌合係止し、オフ位置において係止突部２６がオフ側凹部２８に嵌合係止して、操作部１７のオン位置とオフ位置が不用意に動かないようになっている。
【００１６】
前記電池収納部４と前記発光ダイオード９の収納部１０の上部はカバー３で被覆されている。該カバー３は、これに形成した係止穴３ａに前記電池収納部４の外周壁１３の上部に突設した係止爪１３ａを嵌入係止して、着脱可能に備えられている。
【００１７】
また、前記電池収納部４の底板１４とカバー３の上板３ｂとの間隔は、薄板状のコイン型電池８を収納することから比較的薄く形成され、該電池収納部４が偏平形状になっている。
【００１８】
以上のようであるから、使用に際しては、耳かき部６を耳穴の中に入れて、使用者がスイッチ操作レバー１５を、その操作部１７に指をかけてオン方向Ａ側に回動すると、スイッチ部２１がＡ方向に回動してその傾斜面２１ａの高面が発光ダイオード９の他方のリード線１２を押し上げ、コイン型電池８の＋極８ｂに接触させる。この接触により、一方のリード線１１が常時コイン型電池８の一極８ａに接触しているため、発光ダイオード９が点燈する。この点燈による光は、耳かき棒５内を透過して耳かき部６の周面から外部から発光し、耳穴内を照らす。
【００１９】
この点燈使用中においては、操作部１７の係合突部２６がオン側凹部２７に嵌合係止しているため、操作部１７が不用意に回動して消燈することを防止できる。
【００２０】
また、不使用時には、スイッチ操作レバー１５をオフ方向Ｂ側に回動することにより、スイッチ部２１がＢ方向に回動してその傾斜面２１ａの低面が前記他方のリード線１２に位置し、そのリード線１２がコイン型電池８の＋極８ｂから離間して発光ダイオード９が消燈する。
【００２１】
この消燈中においては、操作部１７の係合突部２６がオフ側凹部２８に嵌合係止しているため、操作部１７が不用意に回動して点燈することを防止でき、保管中に点燈して電池が消耗することを防止できる。
【００２２】
更に、操作部１７のオン方向回動時やオフ方向回動時には、スイッチ部２１がストッパー２２，２３に当接してその回動位置が規制されるため、スイッチ操作レバー１５を強い力で回動しても所定範囲外まで回動せず、確実な点燈又は消燈操作ができ、かつ部品の破損も防止できる。
【００２３】
【発明の効果】
本発明は、前記のように電源としてコイン型電池を使用するとともに電池収納部をコイン型電池の外周面に沿った略円形に形成したので、電池収納部を、薄い円盤状のコイン型電池に沿った偏平で略円形の形状に形成して小型に形成でき、このライト付耳かきの取扱いが容易になる。
【００２４】
更に、前記のように、電池収納部の外周面を前記のように略円形に形成しても、スイッチ操作レバーを、電池収納部の底板に回転中心を有して備えたので、そのスイッチ操作レバーの操作部が電池収納部の外周壁の外面に沿って回動し、この操作部の回動操作、すなわちスイッチ操作がしやすくなる。

It is characterized by doing so.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described based on the examples shown in the drawings.
[0008]
The earpick with a light 1 includes a main body 2 and a cover 3. The main body portion 2 includes a battery housing portion 4, an ear stick 5 protruding from the portion 4, and an ear stick portion 6 formed at the tip of the ear stick 5, and these are made of a translucent material such as a transparent resin. It is molded integrally. Only the earpick 5 and the earpick part 6 may be formed of a transparent material, for example, a transparent resin.
[0009]
The battery housing portion 4 is formed in a concave shape with an upper surface opened in a lower half portion from the substantially axial center of the ear stick 5, and an annular battery support plate 7 is erected inside the battery storage plate 7. A flat and disc-shaped coin-type battery 8 is placed and stored on the upper surface of the battery. A storage portion 10 having an open upper surface for storing a light emitting diode 9 serving as a lighting rod is formed at the boundary between the battery storage portion 4 and the earpick 5, and the light emitting diode 9 is earpicked on the light emitting side of the storage portion 10. The one lead wire 11 is brought into contact with the negative electrode 8a side of the stored coin-type battery 8 toward the rod 5 side, and the other lead wire 12 is brought slightly toward the positive electrode 8b side of the coin-type battery 8 from its pole surface. It protrudes so as to be spaced apart. As shown in FIGS. 4 and 6, both the lead wires 11 and 12 are bent to the side of the coin-type battery 8, and the leading portions 11 a and 12 a are directed substantially in the radial direction of the coin-type battery 8. It is bent like so.
[0010]
The outer peripheral wall 13 of the battery housing portion 4 is formed in a substantially circular shape along the outer periphery of the coin-type battery 8, in the example shown in the figure, an oval (egg-shaped) ring. A switch operation lever 15 is provided on the outer surface of the bottom plate 14 of the battery storage unit 4. As shown in FIG. 3, the switch operating lever 15 is provided so that a pin 16 formed integrally with the switch operating lever 15 is rotatably connected to the bottom plate 14 and is rotated about the pin 16.
[0011]
Further, the other end of the switch operating lever 15 is bent toward the outer peripheral surface side of the outer peripheral wall 13, and the bent portion serves as an operation portion 17. The operation portion 17 is formed in an arc shape centered on the pin 16 with respect to the rotation direction. Further, the outer peripheral wall 13 in the rotation range of the operation unit 17 is formed as a curved wall along the arc of the operation unit 17. Therefore, the operation unit 17 rotates along the outer surface of the outer peripheral wall 13 of the battery storage unit 4.
[0012]
In the example of the figure, the position of the pin 16 that is the center of rotation of the switch operation lever 15 is eccentric as shown in the figure with respect to the center of the battery storage unit 4, but may be the center of the battery storage unit 4. . In addition, an uneven surface 18 for fingers and a projection 19 are integrally formed on the outer surface of the operation portion 17.
[0013]
Further, the switch operating lever 15 is integrally formed with a switch portion 21 that enters the storage chamber from a long hole-shaped window 20 formed in the bottom plate 14 of the battery storage portion 4. The switch portion 21 is provided at a position where the other lead wire 12 of the coin-type battery 8 is engaged with the lower side of the tip portion 12a, and the upper surface of the switch portion 21 is turned on in the turning direction. 6 is formed on the inclined surface 21a, and when turned in the ON direction A shown in FIGS. 6 and 7, the tip 12a of the other lead wire 12 is pushed up by the inclined surface 21a and the coin-type battery 8 When the light emitting diode 9 is turned on in contact with the positive pole 8b and rotated in the off direction B, the leading end 12a of the other lead wire 12 is separated from the positive pole 8b of the coin-type battery 8 by its elastic return force. Thus, the light emitting diode 9 is extinguished.
[0014]
As shown in FIG. 5, one end in the longitudinal direction of the window 20 formed on the bottom plate 14 of the battery housing portion 4 is formed as a stopper 22 that regulates the turning position of the switch portion 21 in the ON direction. Is a stopper 23 for restricting the rotational position in the off direction. Further, the other lead wire 12 of the light emitting diode 9 is adapted to be fitted and supported in a groove 25 formed by the battery support plate 7 and the wall 24 shown in FIG. When the switch portion 21 is pushed in the ON direction A, the lead wire 12 moves upward without escaping in the A direction so that a good ON operation is performed.
[0015]
Further, as shown in FIG. 5, a locking projection 26 is formed on the inner surface of the operation portion 17, and an on-side recess 27 and an off-side recess 28 are formed on the outer surface of the outer peripheral wall 13. The locking projection 26 is fitted and locked to the on-side recess 27 at the on position of the portion 17, and the locking projection 26 is fitted and locked to the off-side recess 28 at the off position, so that the operating portion 17 is turned on. And the off position does not move carelessly.
[0016]
The upper portions of the battery housing portion 4 and the light emitting diode 9 housing portion 10 are covered with a cover 3. The cover 3 is detachably provided by engaging and locking a locking claw 13a projecting from the upper portion of the outer peripheral wall 13 of the battery housing portion 4 in a locking hole 3a formed therein.
[0017]
The space between the bottom plate 14 of the battery storage unit 4 and the upper plate 3b of the cover 3 is formed to be relatively thin because the thin plate-shaped coin-type battery 8 is stored, and the battery storage unit 4 has a flat shape. ing.
[0018]
As described above, in use, when the earpick part 6 is put into the ear hole, and the user turns the switch operating lever 15 with the finger on the operating part 17 and rotates it in the on direction A side, the switch The portion 21 rotates in the A direction, and the high surface of the inclined surface 21 a pushes up the other lead wire 12 of the light emitting diode 9 and makes contact with the positive electrode 8 b of the coin-type battery 8. Due to this contact, one lead wire 11 is always in contact with one pole 8a of the coin-type battery 8, so that the light emitting diode 9 is turned on. The light due to this dot is transmitted through the ear stick 5 and emitted from the outer surface of the ear stick 6 to illuminate the inside of the ear hole.
[0019]
During use of this lighting, the engaging projection 26 of the operating portion 17 is fitted and locked to the on-side recess 27, so that the operating portion 17 can be prevented from rotating unintentionally and disappearing. .
[0020]
When not in use, the switch operating lever 15 is rotated in the off direction B side, whereby the switch portion 21 is rotated in the B direction so that the lower surface of the inclined surface 21a is positioned on the other lead wire 12. The lead wire 12 is separated from the positive electrode 8b of the coin battery 8 and the light emitting diode 9 is extinguished.
[0021]
During the extinction, since the engaging protrusion 26 of the operating portion 17 is fitted and locked to the off-side recessed portion 28, the operating portion 17 can be prevented from turning unintentionally and turning on, It is possible to prevent the battery from being consumed by turning on during storage.
[0022]
Further, when the operation portion 17 is turned in the on direction or in the off direction, the switch portion 21 abuts against the stoppers 22 and 23 and the turning position is restricted, so that the switch operation lever 15 is turned with a strong force. Even if it does not rotate out of the predetermined range, it is possible to perform a reliable lighting or extinguishing operation and to prevent damage to the parts.
[0023]
【The invention's effect】
In the present invention, as described above, the coin-type battery is used as a power source, and the battery storage portion is formed in a substantially circular shape along the outer peripheral surface of the coin-type battery. Therefore, the battery storage portion is formed into a thin disc-shaped coin-type battery. It can be formed in a flat and substantially circular shape and can be made compact, and the earpick with a light can be easily handled.
[0024]
Further, as described above, even if the outer peripheral surface of the battery storage portion is formed in a substantially circular shape as described above, the switch operation lever is provided with the center of rotation on the bottom plate of the battery storage portion.
