Description

【０００１】
【発明の属する技術分野】
この発明は、電池を使用する電子機器に採用される電池収納装置に関し、特に、異種サイズの電池を選択収納できるようにした電池収納装置に関する。
【０００２】
【従来の技術】
一般に、電池を使用する電子機器には、電池を収納する電池ボックスが設けられている。この電池ボックスは、通常、予め決められた種類の電池のみが収納可能なように構成されており、他の種類の電池は収納することができない。
【０００３】
ところで、例えば、防災無線機器等の緊急時に使用する電子機器においては、手元にその電子機器に適した電池があるとは限らないので、種々の電池の使用が可能になる構造が好ましい。
【０００４】
従来、複数種類の電池が使用できるようにした電池収納装置としては、特開平１０−１３４７８５等が知られている。
【０００５】
この特開平１０−１３４７８５に開示された「電子機器における電池収納装置」においては、電子機器の筐体に開口部を有する電池収納凹部内に開口部に対して往復動可能に電池受け台を形成するとともに、この電池受け台の互いに対向する一対の側壁を、筐体に揺動可能にもうけた一対の爪片に係止することにより、電池受け台を２段階の位置に保持させるようにし、この電池受け台と電子機器の筐体の開口部にもうけたカバー体との間に電池を挟着保持することにより、互いにサイズの異なる大小２種類の電池を使用できるように構成されている。
【０００６】
また、図１４に示すように、電子機器８０に設けられた電池収納凹部８１内に、電池ボックス８２を電池収納凹部８１の開口部に対して往復動可能となるようバネ８４を介して電池収納凹部８１の底面に固定するとともに電池収納凹部８１の開口部に設けられた爪片８１ａ、８１ｂにより電池収納凹部８１外部に飛び出さないようにし、この電池ボックス８２に形成された大きい電池の外殻寸法の受け皿８２２およびその壁面に形成された小さい電池の外郭寸法の受け皿８２１のそれぞれと蓋８３との間に密着保持することにより、互いにサイズの異なる大小２種類の電池を使用できるようにした構成も知られている。
【０００７】
また、使用する各種電池それぞれと一対一対応した電池ボックスを複数個用意し、使用する電池にあわせてこの電池ボックスを交換して電子機器に設けられた電池収納用開口部内に装着することにより、複数種類の電池の選択収納を可能にした構成も知られている。
【０００８】
【発明が解決しようとする課題】
ところが、上述した特開平１０−１３４７８５に開示された「電子機器における電池収納装置」および図１４に示した電池収納装置では、３種類以上の電池に対応することができない。
【０００９】
また、各種サイズの電池に一対一対応した複数種類の電池ボックスを用意する構成では、使用していない電池ボックスを紛失してしまうと、緊急時等に手元にある他の種類の電池を有効に使用することができないという問題が生じる。
【００１０】
そこで、この発明は、使用する電池の種類に応じた切替が容易で、しかも３種類以上の電池を選択的に収納して使用でき、かつ電池を選択収納するため部品を紛失してしまう危険性も回避できる電池収納装置を提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記した目的を達成するため、請求項１の発明の電池収納装置は、電池収納用開口部内に回動自在に配設され、第１の回動位置にあるとき第１の電池収納部および第２の電池収納部を画成し、第２の回動位置にあるとき第３の電池収納部を画成する電池切替部材と、前記電池切替部材を前記第１の回動位置に切替たときに、前記第１の電池収納部および第２の電池収納部のいずれか一方に電池が収納された場合は、該収納された電池により回動して他方の電池収納部に対する電池の収納を禁止する禁止部材とを設けたことを特徴とする。
【００１２】
また、請求項２の発明は、請求項１の発明において、前記電池切替部材および前記禁止部材は、同軸に回転自在に支承された第１のレバーおよび第２のレバーからなり、前記第１のレバーは、前記第１の電池収納部に対応して一部が開口した略コの字状の凹部を有し、前記凹部の開口部が電池収納方向を向く前記第１の回動位置にあるとき前記凹部により前記第１の電池収納部を画成するとともに、前記凹部の下側に前記第２の電池収納部を画成し、前記凹部の開口部が下方を向く第２の回動位置にあるとき前記凹部の背面側に第３の電池収納部を画成し、前記第２のレバーは、前記凹部を貫通して下側に突出し、前記第１の電池収納部に電池が収納された場合は、該収納された電池により下方に回動して前記第２の電池収納部に対する電池の収納を禁止し、前記第２の電池収納部に電池が収納された場合は、該収納された電池により上方に回動して前記第１の電池収納部に対する電池の収納を禁止することを特徴とする。
【００１３】
このような構成によると、電池切替部材の切替だけで、３種類の異種電池の収納が可能になり、また、分離可能な構成部品を有さないため、必要な部品を紛失したために、手元にある他の種類の電池を有効に使用することができないという不都合は生じず、さらに、異種電池の混載も防止することができる。
【００２７】
【発明の実施の形態】
以下、この発明に係る電池収納装置の実施の形態を添付図面を参照して詳細に説明する。
【００２８】
図１は、この発明に係る電池収納装置の一実施の形態を示すもので、図示しない電子機器に設られた電池収納用開口部１ａ内に二つのレバー２、３を配設し、単一、単二、単三電池が選択収納できるように構成されている。
【００２９】
電池収納用開口部１ａは、単一電池が収納可能な凹部１１および単二電池が収納可能な凹部１２から成り、この電池収納用開口部１ａ内には、単三電池が収納される凹部２１を有し両端に回転軸２ａ、２ｂを有し回動可能に配設されたレバー２（電池切替部材）と両端に回転軸３ａ、３ｂを有し回動可能に配設されたレバー３（禁止部材）が設けられる。
【００３０】
レバー２は、回転軸２ａ、２ｂを軸として電池収納用開口部１ａ内で自由に回動する。
【００３１】
このレバー２をＡ方向に回動して図１（ａ）に示すような第１の回動位置に位置させれば凹部２１に単三電池が、凹部１１に単一電池がそれぞれ収納でき、Ｂ方向に回動して図１（ｂ）に示すような第２の回動位置に位置させれば凹部１２に単二電池が収納できる。
【００３２】
また、レバー３はその先端がレバー２に形成された孔２２を貫通して配設される。
【００３３】
なお、電池収納用開口部１ａの壁面にはこの壁面によってレバー２およびレバー３の回動が阻害されないように溝１３が形成されている。
【００３４】
このレバー２およびレバー３による単一乃至単三電池の選択収納方法を、図２を参照して更に詳しく説明する。
【００３５】
図２（ａ）は、この形態の電池収納装置に単一電池を収納する場合を示す。この場合、まずレバー２を第一の回動位置に回動し、凹部１１に単一電池を収納する。収納された単一電池は、凹部１１および蓋１４により密着保持される。このとき、収納された単一電池によりレバー３が押しあげられてレバー３が凹部２１に突出し、これにより凹部２１に単三電池が同時に収納されることを禁止する。
【００３６】
また、図２（ｂ）は、この形態の電池収納装置に単三電池を収納する場合を示しており、レバー２は単一電池のときと同様、第１の回動位置に回動し、凹部２１に単三電池を収納する。収納された単三電池は、凹部２１および蓋１４により密着保持される。このとき、収納された単三電池によりレバー３が押し下げられてレバー３が凹部１１に突出し、これにより凹部１１に単一電池が同時に収納されることを禁止する。
【００３７】
更に、図２（ｃ）は、この形態の電池収納装置に単二電池を収納する場合を示しており、レバー２を第２の回動位置に回動し、凹部１２に単二電池を収納する。収納された単二電池は、凹部１２、レバー２、蓋１４により密着保持される。このとき第２の回動位置にあるレバー２が凹部１１に単一電池が同時に収納されることを禁止する。
【００３８】
電池収納用開口部１ａ内には単一乃至単三の各電池に対応した図示しない電極が配設され、上記のように収納された電池はそれぞれこの電極により図示しない電子機器と電気的に接続される。更に、単二電池と単三電池は長さがほぼ同じなため、電極を兼用させることもできる。
【００３９】
図３は、電子機器１０に設けた電池収納用開口部１ｂ内に、出し入れ自由なアダプタ４を用いて単一、単二、単三、単四電池が選択収納できるように構成した電池収納装置の概略斜視図である。
【００４０】
アダプタ４は、上面、下面、側面が長方形で端面が正方形の直方体の形状をしており、長辺まわりに９０度、１８０度回転させて上面、下面、１つの側面を上にして３通りに電池収納用開口部１ｂ内に収納できるように構成されている。
【００４１】
また、アダプタ４には、上面に単一電池を収納できる凹部４１、これに対向する下面に単二電池を収納できる凹部４２および単三電池を収納できる凹部４３、１つの側面に単四電池を収納できる凹部４４がそれぞれ形成されている。
【００４２】
なお、アダプタ４の２つの端面には溝４５が形成され、上記した各凹部にそれぞれ配設された図示しない電極につながる導線４６がアダプタ４の出し入れを阻害しない十分な長さを持って電子機器１０につながり、アダプタ４と電子機器１０が電気的に接続するように構成されている。
【００４３】
図４にこのアダプタ４を用いて各種電池を選択収納したときの様子を示す。
【００４４】
図４（ａ）は、この形態の電池収納装置に単一電池を収納する場合を示し、この場合アダプタ４を上面が上になるように電池収納用開口部１ｂ内に収納する。そしてこのアダプタ４の上面に形成された凹部４１に単一電池が収納される。
【００４５】
図４（ｂ）は、この形態の電池収納装置に単二電池を収納する場合を示し、この場合アダプタ４を下面が上になるように電池収納用開口部１ｂ内に収納する。そしてこのアダプタ４に形成された凹部４２および凹部４３のうち、凹部４２に単二電池が収納される。
【００４６】
図４（ｃ）は、この形態の電池収納装置に単三電池を収納する場合を示し、単二電池と同様、アダプタ４を下面が上になるように電池収納用開口部１ｂ内に収納し、このアダプタ４の下面に形成された凹部４２および凹部４３のうち、凹部４３に単三電池が収納される。
【００４７】
図４（ｄ）は、この形態の電池収納装置に単四電池を収納する場合を示し、この場合アダプタ４は側面が上になるように電池収納用開口部１ｂ内に収納する。そしてこのアダプタ４の側面に形成された凹部４４に単四電池が収納される。
【００４８】
上記のように各凹部に収納された各種電池は、蓋１０ａを閉めることによりそれぞれ各凹部と蓋１０ａの間に密着保持され、各凹部内にそれぞれ配設された図示しない電極により導線４６を介して電子機器１０に電気的に接続される。
【００４９】
なお、ここでは４種類の電池を収納できるようにアダプタ４を構成しているが、３種類の電池にしか対応しないようにも構成でき、逆に５種類以上の電池に対応できるようにも構成できる。
【００５１】
図５（ａ）は、電子機器１０に設けた電池収納用開口部１ｃ内に、２つのアダプタ５２および５３を用いて単一、単二、単三電池が選択収納できるよう構成した電池収納装置の概略図である。
【００５２】
電池収納用開口部１ｃ内には、反転させて収納することが可能で、かつ、電池収納用開口部１ｃ内に設けられた図示しない接点と収納向きに関係なく常に接する接点５２２および５３２が設けられ、この接点により電子機器１０と電気的につながるアダプタ５２および５３が用意されている。
【００５３】
このアダプタ５２には図５（ｂ）のように、凹部５２ａ、５２ｂ、５２ｃの奥壁面にそれぞれ導線５２１を介して接点５２２に電気的につながる端子ばね５２ａ’、５２ｂ’、５２ｃ’が配設される。
【００５４】
またアダプタ５３には図２（ｃ）のように、凹部５３ａ、５３ｂ、５３ｃの奥壁面にそれぞれ導線５３１を介して接点５３２に電気的につながる端子板５３ａ’、５３ｂ’、５３ｃ’が配設される。
【００５５】
なおアダプタ５２およびアダプタ５３は、電池収納用開口部１ｃの内寸Ｌ１とアダプタ５２及びアダプタ５３の各部寸法Ｌ２乃至Ｌ７が以下の関係になるように形成する。
【００５６】
ここで電池の長さは単一電池をＨ１、単二電池をＨ２、単三電池をＨ３とし、またαはどの端子ばねの自然長よりも短めになるよう設定した値である。
【００５７】
Ｌ２＋Ｌ５＋２Ｈ１＋α＝Ｌ１
Ｌ３＋Ｌ６＋２Ｈ２＋α＝Ｌ１
Ｌ４＋Ｌ７＋２Ｈ３＋α＝Ｌ１
図６に上記のように構成した電池収納装置に各種電池を収納したときの様子を示す。
【００５８】
図６（ａ）は、アダプタ５２およびアダプタ５３を凹部５２ａと凹部５３ａが対向するように電池収納用開口部１ｃ内に収納し、凹部５２ａと凹部５３ａとにより画成される電池収納部に二つの単一電池が縦一列に挿入され、端子ばね５２ａ’と端子板５３ａ’の間に電気的に接続保持される様子を示している。
【００５９】
図６（ｂ）は、アダプタ５２およびアダプタ５３を凹部５２ｂと凹部５３ｂが対向するように電池収納用開口部１ｃ内に収納し、凹部５２ｂと凹部５３ｂにより画成される電池収納部に二つの単二電池が縦一列に挿入され、端子ばね５２ｂ’と端子板５３ｂ’ の間に電気的に接続保持される様子を示している。
【００６０】
図６（ｃ）は、アダプタ５２およびアダプタ５３を凹部５２ｃと凹部５３ｃが対向するように電池収納用開口部１ｃ内に収納し、凹部５２ｃと凹部５３ｃとにより画成される電池収納部に二つの単三電池が縦一列に挿入され、端子ばね５２ｃ’と端子板５３ｃ’ の間に電気的に接続保持される様子を示している。
【００６１】
以上説明した単一電池、単二電池、単三電池を選択収納する場合の他にも、アダプタ５２及びアダプタ５３の各部寸法を任意に形成することで、他の種類の電池に対応できる電池収納装置を構成することもできる。
【００６３】
図７（ａ）は、電子機器に設けた電池収納用開口部１ｄ内に、電池収納部６１およびアダプタ６２を用いて単一、単二、単三電池が選択収納できるように構成した電池収納装置の概略図である。
【００６４】
電池収納用開口部１ｄ内には、自由に出し入れでき、かつ、出し入れを阻害しない十分な長さをもった導線６１ｃ、６１ｄを介して電子機器１０と電気的につながる電池収納部６１が用意されている。
【００６５】
この電池収納部６１には、端子板６１１ａ、端子ばね６１１ｂが配設された蓋６１１および端子板６１２ａ、端子ばね６１２ｂ、６１２ｃが配設された蓋６１２により閉じる、対向した二つの電池挿入口が設けられている。
【００６６】
さらに電池収納部６１には二つの電池挿入口の方向（つまり、収納する電池の長手方向）に対して摺導可能なアダプタ６２が内蔵され、このアダプタ６２はその外壁面に設けられた接点６２１ａ、６２２ａにより電池収納部６１の接点６１ａ、６１ｂと常に接し、収納部６１と電子機器１０を電気的につなぐ導線６１ｃ、６１ｄを介して電子機器１０と電気的に接続される。
【００６７】
このように、アダプタ６２を電池収納部６１内において摺動可能にすることよって、電池収納部６１のサイズを小さくすることができる。
【００６８】
例えば、単一電池を収納する場合には、単二および単三電池の収納スペースを確保する必要は無いため、アダプタ６２を摺動可能とすることで、図８（ａ）に示すように、アダプタ６２を電池収納部６１の蓋６１２側に寄せて単一電池の収納スペースを形成することができ、電池収納部６１のスペースを有効に利用できる。ところが、アダプタ６２にこの摺動機能をもたせないと、図８（ｂ）に示すように、単一電池を格納する場合であっても、常に単二および単三電池の収納スペースが確保されてしまうため、電池収納部６１のサイズが大きくなってしまう。
【００６９】
また、アダプタ６２には図７（ｂ）のように、凹部６２ａ、６２ｃ、６２ｅの奥壁面にそれぞれ導線６２２を介して接点６２２ａに電気的につながる端子ばね６２ａ’、６２ｃ’、６２ｅ’が、凹部６２ｂ、６２ｄ、６２ｆの奥壁面にそれぞれ導線６２１を介して接点６２１ａに電気的につながる端子板６２ｂ’、６２ｄ’、６２ｆ’が配設される。
【００７０】
なおアダプタ６２はその各部寸法Ｌ９乃至Ｌ１１が電池収納部６１の内寸Ｌ８と以下の関係になるように形成する。
【００７１】
ここで電池の長さは単一電池をＨ１、単二電池をＨ２、単三電池をＨ３とし、またαはどの端子ばねの自然長よりも短めになるよう設定した値である。
【００７２】
Ｌ９＋Ｈ１＋α＝Ｌ８
Ｌ１０＋Ｈ２＋α＝Ｌ８
Ｌ１１＋Ｈ３＋α＝Ｌ８
図９に上記のように構成した電池収納装置に各種電池を収納したときの様子を示す。
【００７３】
図９（ａ）は、蓋６１１が設けられた電池挿入口より二つの単一電池をアダプタ６２の凹部６２ａ、６２ｂにそれぞれ一つずつ挿入し蓋６１１を閉めることにより、端子ばね６２ａ’と端子板６１１ａの間に一つの単一電池が、端子板６２ｂ’と端子ばね６１１ｂの間にもう一つの単一電池がそれぞれ電気的に接続保持される様子を示している。
【００７４】
図９（ｂ）は、蓋６１２が設けられた電池挿入口より二つの単一電池をアダプタ６２の凹部６２ｃ、６２ｄにそれぞれ一つずつ挿入し蓋６１２を閉めることにより、端子ばね６２ｃ’と端子板６１２ａの間に一つの単二電池が、端子板６２ｄ’と端子ばね６１２ｂの間にもう一つの単二電池がそれぞれ電気的に接続保持される様子を示している。
【００７５】
図９（ｃ）は、蓋６１２が設けられた電池挿入口より二つの単三電池をアダプタ６２の凹部６２ｅ、６２ｆにそれぞれ一つずつ挿入し蓋６１２を閉めることにより、端子ばね６２ｅ’と端子板６１２ａの間に一つの単三電池が、端子板６２ｆ’と端子ばね６１２ｃの間にもう一つの単三電池がそれぞれ電気的に接続保持される様子を示している。
【００７６】
以上説明した単一電池、単二電池、単三電池を選択収納する場合の他にも、アダプタ６２の各部寸法を任意に形成することで他の種類の電池に対応できる電池収納装置を構成することができる。
【００７７】
また、図１０のように、電池収納部６１と同じ形状、構成で、蓋６３１により閉じる電池挿入口を一つだけもつ電池収納部６３を用意し、この蓋６３１に使用するすべての電池に対応した電極を配設すれば、使用したい電池に対する収納凹部が電池挿入口６３１に対向するように使用する電池にあわせてアダプタ６２を左右反転させて電池収納部６３内に収納し、蓋６３１と各凹部との間に密着保持して数種類の電池を選択収納することもできる。
【００７８】
なお、アダプタ５２、５３およびアダプタ６２において、図１１のように単二電池を収納する凹部７ａの壁面に単三電池を収納する凹部７ｂを形成することで、単二電池と単三電池を混載する危険を回避できる。
【００８０】
図１２は、電子機器９０に設けられた電池収納部９１の外観図であり、図１３は、電子機器９０の断面Ａから見た電池収納部９１の内部構造を示す図である。
【００８１】
図１２において、電子機器９０には、蓋９３を有する電池収納部９１が設けられ、単一、単二、単三電池が選択収納できるように構成されている。
【００８２】
この、電池収納部９１に、上記３種類の電池が選択収納される様子を図１３に示す。
【００８３】
電池収納部９１は、単一電池の収納が可能な凹部９１１、単二電池の収納が可能な凹部９１２、単三電池の収納が可能な凹部９１３が形成され、これら各種電池の選択収納を可能とするため、摺動可能に配設されたアダプタ９２が設けられている。
【００８４】
図１３（ａ）は、電池収納部９１の凹部９１１に単一電池を収納する場合を示す。電池収納部９１の凹部９１１に収納された単一電池は凹部９１１とアダプタ９２の凹部９２１との間に密着保持され、このとき、アダプタ９２の凸部９２４および凸部９２５は、それぞれ電池収納部９１の凹部９１２および凹部９１３に突出して、電池収納部９１の凹部９１２に単二電池、電池収納部９１の凹部９１３に単三電池が収納されることを禁じる。
【００８５】
また、図１３（ｂ）は、電池収納部９１の凹部９１２に単二電池を収納する場合を示し、電池収納部９１の凹部９１２に収納された単二電池は凹部９１２とアダプタ９２の凹部９２２との間に密着保持され、このとき、アダプタ９２の凸部９２４および凸部９２５は、それぞれ電池収納部９１の凹部９１１および電池収納部９１の凹部９１２に突出して、電池収納部９１の凹部９１１に単一電池、電池収納部９１の凹部９１３に単三電池が収納されることを禁じる。
【００８６】
さらに、図１３（ｃ）は、電池収納部９１の凹部９１３に単三電池を収納する場合を示し、電池収納部９１の凹部９１３に収納された単三電池は電池収納部９１の凹部９１３とアダプタ９２の凹部９２３との間に密着保持され、このとき、アダプタ９２の凸部９２４および凸部９２５は、それぞれ電池収納部９１の凹部９１２および電池収納部９１の凹部９１１に突出して、電池収納部９１の凹部９１１に単一電池、電池収納部９１の凹部９１２に単二電池が収納されることを禁じる。
【００８７】
なお、電池収納部９０には、単一、単二、単三電池にそれぞれ対応した図示しない電極が設けられ、上記のように収納された各種電池は、それぞれこの電極によって電子機器９０と電気的に接続される。
【００８８】
なお、上記した各種アダプタおよび電池収納部と電子機器との電気的な接続法は上記に限らず、導線によっても接点によっても良い。
【００８９】
【発明の効果】
以上説明したように、この発明によれば、３種類以上の電池を選択収納でき、かつ選択収納するための切替部品を紛失することもないので、例えば防災時に電池の種類に限定されることなく手元にある電池を用いて防災無線機器を動作させることができるなど、電池の種類によって電子機器が使用できないという事態を避けることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a battery storage device employed in an electronic device that uses a battery, and more particularly to a battery storage device that can selectively store batteries of different sizes.
[0002]
[Prior art]
In general, an electronic device using a battery is provided with a battery box for storing the battery. This battery box is normally configured so that only a predetermined type of battery can be stored, and other types of batteries cannot be stored.
[0003]
By the way, for example, in an electronic device used in an emergency, such as a disaster prevention wireless device, there is not always a battery suitable for the electronic device, so a structure that allows the use of various batteries is preferable.
[0004]
Conventionally, Japanese Patent Laid-Open No. 10-134785 is known as a battery storage device that can use a plurality of types of batteries.
[0005]
In the “battery storage device in an electronic device” disclosed in Japanese Patent Laid-Open No. 10-134785, a battery cradle is formed in a battery storage recess having an opening in the casing of the electronic device so as to be reciprocable with respect to the opening. In addition, the battery cradle is held at a two-stage position by engaging a pair of opposite side walls of the battery cradle with a pair of claw pieces swingably mounted on the housing, The battery is sandwiched and held between the battery cradle and a cover body provided in the opening of the casing of the electronic device, so that two types of large and small batteries having different sizes can be used.
