Description

【０００１】
【発明の属する技術分野】
本発明は、自転車の車輪に取り付けられる発光信号器に関するものである。
【０００２】
【従来の技術】
自転車の車輪のスポークに取り付けられ、自動車のライトを反射することによって夜間に自動車運転者から道路を横断中の自転車が視認され易いようするプラスチック製の再帰反射鏡は従来から知られている。
【０００３】
【発明が解決しようとする課題】
しかしながら、単にライトを反射するだけでは、道路脇から飛び出してくる自転車を早期に発見できないので、充分な事故対策になっていない欠点があった。
【０００４】
【課題を解決するための手段】
そこで本発明は、自ら発光する車輪取付用発光信号器を提供し、上記課題を解決しようとするものである。そのために本発明は、自転車の車輪のスポークに固着される取付座板と、該取付座板に着脱自在に取り付けられる発光信号器本体とからなり、該取付座板に永久磁石を設け、該発光信号器本体は透明プラスチック製のケース内に電池と発光ダイオードと振動開閉接点とリードスイッチと手動スイッチを設け、該電池を電源とする該発光ダイオードの電源回路に前記リードスイッチと手動スイッチとを並列に接続し、該発光ダイオードに前記振動開閉接点を直列に接続し、該発光信号器本体を該取付座板に取り付けることにより前記永久磁石の磁力によりリードスイッチがオンすることで自転車走行時の振動により前記振動開閉接点が開閉したとき前記発光ダイオードが点滅すると共に、該発光信号器本体を該取付座板から取り外したときはリードスイッチがオフし前記手動スイッチをオンすることで携帯時の振動により前記振動開閉接点が開閉したとき前記発光ダイオードが点滅するようにしたことを特徴とする。
【０００５】
【発明の実施の形態】
次に図面と共に本発明の実施の形態を図面と共に説明する。図１にこの車輪取付用発光信号器を斜視図にて示し、図２にその取付使用状態、図３にそのＡ−Ａ線断面を示す。本発明の車輪取付用発光信号器は取付座板１と発光信号器本体２とからなる。取付座板１は、自転車車輪のスポーク８，８に係合する鉤状係合片３，３が両端部に形成され、中間部に発光信号器本体２を抱持し得るコ字形状の保持部４が形成されたもので、５，５は該保持部４の円弧状内周面に突設された案内突条である。また、６は保持部４の近くに粒状の永久磁石７を位置させるために取付座板１に形成した小円筒状の磁石抱持部である。
【０００６】
発光信号器本体２は、図４，図５にも示したように、透明プラスチック製のケース１０内に、ボタン型の電池１１と発光ダイオード１２と振動開閉接点１３とリードスイッチ１４と手動スイッチ１５を設けてなり、図６にはその各部品の回路図を示す。
【０００７】
ケース１０は略円盤形のケース半割体１０ａとケース半割体１０ｂからなり、ケース半割体１０ａの外周面の一部に形成された係合片１６にケース半割体１０ｂの外周面の一部に延設された突片１７を係合させると共に、両半割体間に水封用Ｏリング１８を介在させ、ケース半割体１０ａの他方の外周に延設された止着部１９とケース半割体１０ｂに延設された止着部２０にビス２１を貫挿し、両半割体を結合してなる。そしてケース半割体１０ａとケース半割体１０ｂの内面に自動車のライトをその入射方向に反射させ得る凹凸状の再帰反射鏡面２２が形成されている。また２３，２３は前記案内突条５，５に合致するべくケース半割体１０ｂの外周面に形成された案内凹条である。
【０００８】
２４，２５は電池１１および手動スイッチ１５を支持するためケース半割体１０ａ内に形成された台部で、該手動スイッチ１５は該台部２５に支持されその摘み２６をケース半割体１０ｂの外周に露出させている。また２７はボス２８により基部をケース内に固着した薄手金属板からなる導電性弾性部材で、該導電性弾性部材２７の一端に電池１１の外周面に接する導電端子３１が形成され、他方は長手の自由振動片３２が延設され該自由振動片の先端に重錘３３が止着されている。また３５はケース半割体１０ａ内に支柱３６により支持されたプリント基板で、該プリント基板３５には発光ダイオード１２，リードスイッチ１４が止着されているほか、電池１１の下面に接する導電性突部３７が形成され、また下面には前記自由振動片３２の側面に対向する導電性のピン３８が突設され該自由振動片３２とピン３８とで振動開閉接点１３を構成している。なお４０は止着部２０に挿通された携帯用リングである。
【０００９】
このように構成した発光信号器本体２は、スポーク８に取り付けられた取付座板１の保持部４の案内突条５，５に案内凹条２３，２３を合致させスライドすることにより着脱自在に取り付けられる。取り付けた時は該本体２に車輪の回転による外向きの遠心力が加わるので振動で外れるようなおそれはない。そして永久磁石７の磁力により本体２内のリードスイッチ１４がオンする。このため、重錘３３が付いた自由振動片３２がこの自転車の走行時の振動によりピン３８に断続的に接触し、該接点１３を開閉させ、電池１１を電源とする発光ダイオード１２を点滅させる。従ってこの光の点滅により自転車を夜間でも遠くからでも視認できるようになる。
【００１０】
なお、該発光信号器本体２は使用しないときは、車輪の中心方向に押すだけで取付座板１から簡単に取り外すことができる。このため非使用時に前記リング４０に紐を通し手動スイッチ１５をオンにすれば、歩行時に点滅する発光ペンダントのようなアクセサリーとして携帯することも可能である。
【００１１】
【発明の効果】
このように本発明に係る車輪取付用発光信号器は、簡単な構造で走行時の振動により発光ダイオードが点滅するようにしたので、夜間でも自転車を遠くから視認できるようになり、交通事故の防止に顕著な効果がある。

When the vibration switching contact opens and closes, the light emitting diode blinks, and when the light emitting signal device body is removed from the mounting seat plate, the light emitting diode blinks. De switch, wherein the light-emitting diode was made to blink when the oscillating switching contacts by vibration during mobile by turning on the manual switch is turned off is opened and closed.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the wheel-mounted light emitting signal device, FIG. 2 is a diagram showing a mounting use state thereof, and FIG. The wheel mounting light emitting signal device of the present invention comprises a mounting seat plate 1 and a light emitting signal device body 2. The mounting seat plate 1 has hook-shaped engagement pieces 3 and 3 that engage with the spokes 8 and 8 of the bicycle wheel at both ends, and a U-shaped holding member that can hold the light-emitting signal device body 2 in the middle portion. A portion 4 is formed, and 5 and 5 are guide protrusions protruding from the arcuate inner peripheral surface of the holding portion 4. Reference numeral 6 denotes a small cylindrical magnet holding portion formed on the mounting seat plate 1 in order to position the granular permanent magnet 7 near the holding portion 4.
[0006]
As shown in FIGS. 4 and 5, the light emitting signal body 2 includes a button-type battery 11, a light emitting diode 12, a vibration switching contact 13, a reed switch 14, and a manual switch 15 in a transparent plastic case 10. FIG. 6 shows a circuit diagram of each component.
[0007]
The case 10 includes a substantially disc-shaped case half 10a and a case half 10b, and an engagement piece 16 formed on a part of the outer periphery of the case half 10a is provided with an outer peripheral surface of the case half 10b. A projecting piece 17 extending in part is engaged, and a water sealing O-ring 18 is interposed between the two halves, and a fastening part 19 extending on the other outer periphery of the case half 10a. A screw 21 is inserted into a fastening portion 20 extending from the case half 10b, and both halves are joined. A concave-convex retroreflecting mirror surface 22 is formed on the inner surfaces of the case half 10a and the case half 10b to reflect the vehicle light in the incident direction. Reference numerals 23 and 23 are guide recesses formed on the outer peripheral surface of the case half 10 b so as to match the guide protrusions 5 and 5.
[0008]
Reference numerals 24 and 25 denote pedestals formed in the case half 10a for supporting the battery 11 and the manual switch 15. The manual switch 15 is supported by the pedestal 25 and the knob 26 is connected to the case half 10b. It is exposed to the outer periphery. Reference numeral 27 denotes a conductive elastic member made of a thin metal plate whose base is fixed inside the case by a boss 28. A conductive terminal 31 that contacts the outer peripheral surface of the battery 11 is formed at one end of the conductive elastic member 27, and the other is a longitudinal member. The free vibration piece 32 is extended, and a weight 33 is fixed to the tip of the free vibration piece. Reference numeral 35 denotes a printed circuit board that is supported in the case half 10a by a support 36. The light emitting diode 12 and the reed switch 14 are fixed to the printed circuit board 35, and conductive bumps that are in contact with the lower surface of the battery 11. A portion 37 is formed, and a conductive pin 38 is provided on the lower surface to face the side surface of the free vibration piece 32, and the free vibration piece 32 and the pin 38 constitute the vibration switching contact 13. Reference numeral 40 denotes a portable ring inserted through the fastening portion 20.
[0009]
The light-emitting signal device body 2 configured as described above is detachable by sliding the guide recesses 23 and 23 in alignment with the guide protrusions 5 and 5 of the holding portion 4 of the mounting seat 1 attached to the spoke 8. It is attached. When attached, since an outward centrifugal force due to the rotation of the wheel is applied to the main body 2, there is no possibility that it will come off due to vibration. The reed switch 14 in the main body 2 is turned on by the magnetic force of the permanent magnet 7. For this reason, the free vibration piece 32 with the weight 33 is intermittently brought into contact with the pin 38 by the vibration during the running of the bicycle, the contact 13 is opened and closed, and the light emitting diode 12 using the battery 11 as the power source is blinked. . Therefore, the blinking of the light makes it possible to see the bicycle at night or from a distance.
[0010]
When the light emitting signal body 2 is not used, it can be easily detached from the mounting seat plate 1 simply by pushing it toward the center of the wheel. For this reason, if the manual switch 15 is turned on by passing a string through the ring 40 when not in use, it can be carried as an accessory such as a light-emitting pendant that flashes during walking.
[0011]
【The invention's effect】
As described above, the wheel-mounted light emitting signal device according to the present invention has a simple structure so that the light emitting diode blinks due to vibration during traveling, so that the bicycle can be seen from a distance even at night, thereby preventing traffic accidents. Has a noticeable effect.
