Description

【0001】
【発明の属する技術分野】
本発明は、ニッケル水素電池やリチウムイオン電池などの充電池や乾電池などの、大きさの異なる2種類の電池で動作することの可能なポータブル機器の電池収納部分に関する。
【0002】
【従来の技術】
ポータブルカセットステレオなど、家庭用電源を使用せず、電池を用いて使用する機器において、通常ランニングコストの面から、充電池が使用されることが多い。しかし、充電切れなどの非常時においては一般に市販されている乾電池を使用できる機能がある方がユーザにとって便利である。この為に、例えば単3乾電池と同一形状の充電池を使用することが考えられるが、既存の規格にとらわれず、できるだけ省スペースで大容量の専用電池を用いた方が、通常使用時における連続使用時間を長くできる点で好ましい。
【0003】
従って、例えば単3乾電池と専用の小型角形電池の2種類の電池をコンパチブルに使用できるように、図3に示すような電池収納ケース19が考えられている。正面[正面図(イ)参照]から見ると、単3乾電池6の外形は、角形充電池7の外形の内側に収まるが、上面[平面図(ロ)参照]から見ると、夫々が他方の外形よりも外側に突出している部分があるため、その突出部にあった切り欠きをケースに設けることによって2種類の大きさの電池の位置決めを可能としている。
【0004】
【発明が解決しようとする課題】
しかしながら、消費電力の大きな機器の場合、連続使用時間を長くするためには充電池の大きさが大きくなり、正面から見ても、上面から見ても単3乾電池が充電池の外形より内側に収まってしまう場合がある。図4はこれを上面より見た場合を示している。このような場合には、上記のようなケースに切り欠きを設ける方法では、小さい方の電池の位置決めが不可能である。
【0005】
本発明は、2種類の電池の一方が、他方よりも長さと、幅または径が何れも大きい場合に、夫々を位置決め可能な電池収納装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記目的を解決するために、本発明は、開口部と、該開口部を開閉する蓋を備え、第1の電池を収納する際に位置を制御する第1のストッパーと、第1の電池よりも長さが長く、幅または径が大きな第2の電池を収納する際に位置を制御する第2のストッパーと、その際に第1のストッパーを回避する回避手段とを備え、前記回避手段は、第1の電池とは接触せず、第2の電池とは接触する位置に移動可能に取り付けられた係合部材と、前記係合部材の移動によってスライドするガイドレバーと、一端に前記第1のストッパーが固着され、他端が前記ガイドレバーと接触する回動部材とより成っている。
【0007】
この構成によると、第1の電池を収納する際には、ケース内に挿入された電池は第1のストッパーによって位置決めされ、第2の電池を収納する際には、前記係合部材が第2の電池の端部と接触しながら移動し、該係合部材の移動によって、前記ガイドレバーがスライドして前記回動部材と接触することにより、前記第1のストッパーを前記回動部材と共に前記電池収納装置の側壁部まで回動させる。
また、前記蓋を閉じ、前記蓋と前記第1のストッパー又は前記第2のストッパーとによって第1の電池又は第2の電池を挟むことで、第1の電池又は第2の電池を出し入れする方向の平行方向において、第1の電池又は第2の電池を固定する。
【0008】
さらに、本発明は、前記蓋に第1の電池又は第2の電池の一方の端子と接続する第1の端子が設けられており、前記第1のストッパーに第1の電池の他方の端子に接続する第2の端子が設けられており、前記第2のストッパーに第2の電池の他方の端子に接続する第3の端子が設けられており、前記第1の端子と前記第2の端子又は前記第3の端子を通して第1の電池又は第2の電池を外部に電気的に接続することが望ましい。
【0009】
この構成によると、夫々の電池は位置決めが行われるとともに、上蓋部分に取り付けられたもう一方の端子との間で回路を閉じ、電圧が取り出されることになる。
【0011】
上記構成によると、第2の電池を挿入していくと、電池端部と係合部材とが接触し、さらに進行すると係合部材が引っ掛かりながら押し進められることによって回動部材が回動し、それに接続された第1のストッパーが側壁部まで回動する事で、電池を挿入する進路が確保される。電池は空いた空間をさらに進行して第2のストッパーによって位置決めされる。
【0012】
【発明の実施の形態】
本発明の実施形態を図を用いて説明する。図4は、先にも述べたものであるが、本実施形態の電池収納部20に、単3乾電池6と充電池8の両方を挿入した状態を示す上面図である。単3乾電池6の直径は、充電池8の幅及び径よりも小さいため、充電池8の内側にすっぽり入ってしまい、電池収納部20の形状で夫々を位置決めできるように構成することは困難である。
【0013】
図1において(a)は、本実施形態の電池収納装置を側面から見た図であり、(b)は、電池収納部20に、単3乾電池6を挿入した状態を示す正面図である。電池収納部20は、電池を案内する側壁12を持ち、側壁12には、係合部材取り付け部11,回動部材取り付け部16,充電池用の第2のストッパー9が固定されている。ガイドレバー2は、側壁12上を図の上下方向にスライド可能なように長穴21を通して縦断面がT字型をした位置決めピン15によって固定され、長穴21の両端に位置決めピン15が突き当たることで、ガイドレバー2のストローク10が決定される。
【0014】
係合部材取り付け部11には、回転軸3aによって回転可能な係合部材5aが、単3乾電池6とは接触せず、充電池8とは接触する位置に取り付けられ、その一端には回転可能なように係合部材5bが取り付けられる。係合部材5bの他端は、ガイドレバー2の垂直部に、回転軸3bによって回転可能なように取り付けられ、係合部材5aの移動によってガイドレバー2が側壁12に沿ってスライドするようになっている。
【0015】
回動部材取り付け部16には、回転軸3cによって回転可能な回動部材4が取り付けられており、一端には単3乾電池用の第1のストッパー1が固着されている。他端は、スライドレバー2と接触しており、スライドレバー2の移動により回動部材4及び第1のストッパー1が回動可能となっている。また、電池収納部20の上部には、上蓋13とそれに固定された板バネ状の端子14が取り付けられており、上蓋13を開いたときにこの方向より電池が挿入されるようになっている。
【0016】
このような構造の電池収納装置において、単3乾電池6を収納する際には、ガイドレバー2と側壁12を繋ぐ、図示しない第1のバネによって、ガイドレバー2は、上蓋13方向に引っ張られ、位置決めピンによって位置決めされる。
【0017】
また、回動部材4と側壁12を繋ぐ図示しない第2のバネによって、回動部材4は、回転軸3cを中心に図中、時計回りに力を受け、ガイドレバー2の端部と突き当たることによって位置決めされる。第2のバネは、回転軸3cを中心としたねじりバネを用いてもよい。
【0018】
これらにより、ガイドレバー2、係合部材5a,5b、回動部材4及び第1のストッパー1は、夫々図1に示す位置に設置され、上蓋13を閉じることによって単3乾電池6は、第1のストッパー1と端子14に挟まれて固定される。
【0019】
また、充電池8を使用する際には、挿入された充電池8の端部が、係合部材5a,5bと接触しながら移動するに従って、図中、ガイドレバー2が下方に、回動部材4が反時計回りに移動し、第1のストッパー1が側壁12の方向へ回転しながら移動する。このようにして、第1のストッパー1によって遮られていた充電池8の進路が確保されることにより、さらに充電池8を移動させ、板バネ状の第2のストッパー9が、充電池8の切り欠き部8aに入り込むことで、図2に示すように位置決めが行われる。
【0020】
この実施形態において、第1のストッパー1と第2のストッパー9は、端子の機能を兼ねている。ストッパーとしての機能だけを持たせて、端子は別途作成してもよいが、部品点数を削減できるので、端子を兼ねた構成とする方が望ましい。
【0021】
また、第1のストッパーに単3乾電池の側面を指示する円筒面を設けることや、係合部材5a,5bに単3乾電池用の案内部品を取り付けることにより、単3乾電池6の直径方向の位置決めを容易に行うようにすることも可能である。なお、上記案内部品は、充電池を使用する際には、係合部材5a,5bとともに側壁へ移動し、充電池の挿入を妨げない構造とする必要がある。
【0022】
以上の説明から明らかなように、第1のストッパー1と、第2のストッパー9と、係合部材5a,5bや回動部材4などにより構成される第1のストッパー1の回避手段とを備えることで、単3乾電池6と、それよりも長さが長く、径または幅の大きい充電池8の2種類の電池をコンパチブルに使用することが可能である。
【0023】
ここで、単3乾電池6としているのは、説明の便宜上用いているのであって、単1乾電池や他の大きさや形状の電池においても同様の効果を得ることができることは明白である。
【0024】
【発明の効果】
本発明の構成によれば、第1の電池と、それよりも長さが長く、径または幅の大きな第2の電池をほぼ第2の電池を収納できるだけの体積の装置でコンパチブルに使用して、ポータブル機器を稼働することが可能となる。
【0025】
また、上記第1のストッパーと第2のストッパーは、電池の端子の機能を兼ね備えていることから、部品点数を削減することが可能である。
【0026】
さらに、上記第1のストッパーの回避手段は、第2の電池端部と係合する係合部材と、この変位によって第1のストッパーを側壁まで回動する回動部材とを備えることにより簡単に構成することが可能である。
