【発明の属する技術分野】
本発明はカメラ、ラジオ等々の携帯用機器において乾電池を収納する電池室の構造の改良に関し、特に単三電池等の円筒状の電池を2本以上並列して収納する電池室において、狭い取出し口から順序よく電池を取出し得るようにした電池室の構造に関する。
【0002】
【従来の技術】
単三電池などの円筒状の乾電池を2本以上電池室内に並列状態に収納して電源として使用するカメラやラジオ等の携帯機器において、電池室から電池を取出す際に、従来は電池の端部を爪などで引っ掛けて取出す必要があった。しかし、電池室内に設けたバネ状の端子が電池端部の電極を強く保持している場合や、電池端部と電池室内壁との間に隙間が少ない場合等においては、爪等によって電池端部を引っ掛けて取出すことが容易でないという欠点があった。
このため、従来は、図4(a)(b)に示すように、電池室100を、電池ケース101と、リボン102から構成し、電池ケース101の内壁に一端102aを固定したリボン102を内壁に沿って敷いておき、電池105a、105bを収納する時にはリボン上に電池105a、105b、105cを並列して配置し、電池取出し時にはリボン102の他端102bをつまんで引き上げることで、電池取出し口103から電池をその径方向へ取出すようにしている。
ところで、携帯機器のデザイン上、機器の外観形状が収納する円筒状の電池の形状に沿った曲面に形作られることが多くある。そのような場合、電池の取出し口103の幅寸法W1が、収納する全ての電池105の直径d1を合計した寸法よりも小さく設計されることがある。この場合、取出し口103から電池を収納、或いは取出す際に、各電池の収納或いは取出しの順序を間違えると、電池を収納或いは取出しできなくなることがある。
このような不具合に対応するために、従来は図4に示したように全ての電池105の下にリボン102を敷いておき、最初に取出す電池105aの側からリボンの他端102bを引き出すようにしていたが、この方法では、図4(a)(b)に夫々示すように、全ての電池が同時に移動を始め、電池同士がぶつかり合い、取出し口103を塞いでしまうためスムーズに取出すことはできなかった。

【発明が解決しようとする課題】
本発明は上記に鑑みてなされたものであり、円筒状の電池を複数個並列に収納する電池ケースと、電池ケース内に配設されて電池取出し時に端部を引き出すことによって電池を電池ケースの狭い取出し口から取出すように構成したリボンと、を備えた電池室の構造において、リボンの固定位置、及び配回し構造を工夫することによって、狭い取出し口から近い順に順序よく詰まりを起こすことなく電池を取出し得るように構成した電池室の構造を提供することを課題とする。
【0004】
【課題を解決するための手段】
上記の課題を解決するため、請求項1の発明は、円筒形状の電池を複数個並列して収納する収納空所と、該収納空所を形成する周壁の一部に開口形成されて収納空所内の電池を一個ずつ径方向へ取出し可能とする電池取出し口と、を備え、前記電池取出し口の幅が収納空所内に収納可能な全電池の合計直径よりも狭く設定されている電池ケースと、一端の固定部を前記収納空所内壁に固定されると共に中間の巻き付き部を収納された全電池の外周に巻き付けられ且つ他端の把持部が電池取出し口から引き出し可能に配設された電池取出し用のリボンと、を備えた電池室において、前記リボンは、収納空所内において最初に取出す位置にある電池の外周の半周以上に巻き付くように構成されていることを特徴とする。
複数の円筒状電池を並列収納する収納空所の周壁に電池着脱用の電池取出し口を開口形成し、且つ取出し口の幅が2個の電池を同時に取出すことができない程度に狭い場合、収納空所の内壁に沿ってリボンを配回し、電池収納時にはこのリボン上に電池を支持するとともに、電池取出し時にはリボンの一端を取出し口から引き出すことにより電池を取出す構成が採用される。この場合に、リボンを引っ張ることにより2個以上の電池が取出し口に向けて同時に移動すると、狭い取出し口に詰まって取出しが困難となる。
そこで、本発明では、リボンを引っ張った時に取出し口に最も近い位置にある電池だけが先行して引き出され、その後は隣接する電池が順次引き出されるようにリボンを電池に巻掛ける手順を工夫した。具体的には、リボンの遊端状の端部(把持部)に近い巻き付き部を取出し口に近い第1の電池の外周の半周以上に巻き付けるようにしたので、リボンの把持部を取出し口から外へ向けて引っ張ったときに真っ先に第1の電池が引き出され、その際に隣接する電池等の残りの電池は全く挙動しない。このため狭い取出し口において、複数の電池が衝突して詰まりを起こすことがなくなる。このようなリボンの配回し方法を、リボン自体、或いは電池室の外側に表示して電池のセットの仕方を指示しておくことにより、操作者は間違いなく容易にリボン及び電池をセットすることができ、電池取出し時にはリボンを引っ張るだけで取出し口に近い側の電池からスムーズに全ての電池を順序よく取出すことが可能となる。
【0005】
請求項2の発明は、請求項1において、前記電池取出し口は、前記収納空所内における電池配列方向に対して、前記最初に取出す電池と対面する位置寄りに偏位して設けられており、前記リボンは、前記固定部に近い前記巻き付き部から前記収納空所内壁に沿って添設されて前記最初に取出す電池以外の電池の外周を包囲するように巻き付き、更に前記最初に取出す電池とその隣の電池との間に入り込んでから前記最初に取出す電池の外周を包囲するようにS字状に巻き付いて前記電池取出し口に前記把持部が位置するように配設されることを特徴とする。
リボンの巻き付き部は、リボンの固定部に近い方が後から取出される電池(第2の電池以降の電池)の外周を包囲するように配置され、更に折り返した巻き付き部は先に取出される第1の電池と第2の電池との間に入り込んでから第1の電池の外周に巻き付くことにより、全体としてS字を形成している。このため、リボンの把持部を引き出した当初には、第1の電池を支持した巻き付き部分のみが引き出され、当該巻き付き部分に支持された第1の電池のみが取出し口から取出される一方で、S字状に配回されたリボンの巻き付き部の残りの部分によって支持された残りの電池はリボンによって引き出されることがなくほぼ静止している。第1の電池取出し後に、引き続いてリボンを引き出すことにより、第2の電池以降の電池を支持した巻き付き部分が引張り力を受けるため、第2の電池が始めて動作を開始し、取出し口から取出される。更に、第3、第4の電池が並列配置されている場合には、順次、順序よく取出され、詰まりを起こすことがない。
請求項3の発明では、請求項1又は2において、前記リボンの固定部は、前記最初に取出す電池とその隣の電池との中間に相当する収納空所の内壁部分から、前記最初に取出す電池の側方に相当する内壁部分の範囲に固定されることを特徴とする。
リボンの固定部を収納空所内壁に固定する位置を、上記範囲外にした場合、例えば第1と第2の電池の中間位置よりも、第2の電池寄りの位置に配置した場合には、リボンをS字状に配回したとしても、リボン端部を引き出したときに、第2の電池を支持する巻き付き部に引張力が作用してしまい、第1の電池のみならず、第2の電池までも引き出し方向へ引っ張られてしまうこととなる。従って、リボンの固定部を配置する範囲の一方の限界位置は、第1と第2の電池の中間位置になる。また、固定部を配置する範囲の他方の限界位置は、第1の電池の側方に相当する内壁の位置である。このようにすることにより、第1の電池を出した後で更にリボンを引っ張ったときに第2の電池に作用する力が増大し、第2の電池以降の電池を大きく移動させて取出し口の外側へ押し出すことが可能となる。
【0006】
【発明の実施の形態】
以下、本発明を図面に示した実施の形態により詳細に説明する。
図1(a)及び(b)は本発明の一実施形態に係る電池室の構造を示す断面図である。
この電池室1は、図示しない携帯機器の一部を構成しており、複数個の円筒状の電池B1、B2を出入れ自在に収納する電池ケース2と、電池ケース2内に配置されるリボン3と、を備えている。
図1(a)(b)に示すように、電池ケース2は、複数個の円筒形状の電池B1、B2を並列状態で近接して収納する収納空所11と、該収納空所11を形成する周壁12の一部に開口形成されて収納空所11内の第1及び第2の電池B1、B2を一個ずつ径方向(電池の軸方向と直交する方向)へ取出し可能とする電池取出し口13と、を備える。電池取出し口13は、収納空所の周壁12の上側壁部に開口形成されており、電池取出し口13の開口幅W1は、収納空所11内に収納可能な全ての電池の直径d1を合計した寸法よりも狭く設定されている。この実施形態では、第1及び第2の電池B1、B2を横方向に並列配置しているため、収納空所11は横長形状となっており、その周壁12の上部に電池取出し口13が開口形成され、電池取出し口13と対向する下方に収納空所の底部11aが位置している。電池取出し口13の奥行き方向寸法は、電池を取出し可能なように、電池の軸方向長よりも少し大きく設定されている。電池取出し口13の開口幅W1は、レイアウト上の理由等から、収納した全ての電池B1、B2を一括して取り出せないように、全電池の直径d1の合計寸法よりも狭く設定されている。また、電池取出し口13は、収納空所の底部11aの幅方向中央部よりも、最初に取出す電池B1寄りに偏位して配置されている。このため、後述するリボン3の引き出し操作によって、奥側に位置する第2の電池B2を先に取出すことはできず、必ず取出し口13に近い第1の電池B1が先に取り出されることとなる。しかも、第1の電池が取出し口から取り出される過程で、第2の電池はリボンによって移動されることがなく、2つの電池が取出し口で詰まることがなくなる。
【0007】
リボン3は、図1(a)に示すように、例えば細幅帯状で電池を安定して保持できる幅を有した可撓性の絶縁シートから構成された電池取出し手段である。リボン3の一端の固定部3aを収納空所11の内壁(底部11a)に固定すると共に、中間の巻き付き部3bを収納された全電池B1、B2の外周にS字状に巻き付け、且つ他端の把持部3cを電池取出し口13から引き出し可能に配設している。
リボンの固定部3aは、この例では、収納空所11の底部11a上の、最初に取出す第1の電池B1と、隣接する第2の電池B2との間に相当する位置(中間位置)に固定され、リボンの巻き付き部3bは、少なくとも最初に取出す電池B1の外周の半周以上に巻き付くように構成されている。このため、把持部3cを取出し方向Aへ引っ張った時に、第1の電池B1だけが同方向へ移動し、第2の電池B2はほとんど静止した状態にある。
更に、具体的には、リボンの巻き付き部3bは、固定部3aに近い部分から収納空所内壁に沿うように添設されて、最初に取出す電池B1以外の電池B2の外周(ほぼ全周)を反時計回りに包囲するように巻き付き、更に最初に取出す電池B1とその隣の電池B2との間隙に上側から入り込んでから最初に取出す電池B1の外周を時計廻りに包囲するように、全体としてS字状に巻き付いて、電池取出し口13内に把持部3cが位置するように配設される。
このため、図1(b)に示すように、リボン3の把持部3cを指等によって把持して(つまんで)、矢印で示す電池の軸方向と直交する方向Aへ引き出すことにより、真っ先に電池B1だけを矢印B方向へ取出すことができる。このとき、電池B2はリボンによって固定され殆ど動かない。電池B1が取り外された後、さらにリボンを引くと電池B2がリボンによって引き出され、2本の電池とも容易に取り外すことができる。
【0008】
固定部3aを内壁に固定する位置を図示した中間位置よりも第2の電池寄りに大きく変位した位置(例えば、図4に示した位置102a)に配置した場合には、リボンを引っ張って第1の電池を取出す動作とほぼ連動して第2の電池もリボンによって順次引っ張られ、両電池が狭い取出し口にて詰まりを起こす虞がある。つまり、図1のように固定部3aが中間位置内にある限り、把持部3cをA方向へ引き出したときに第1の電池を支持する巻き付き部分3b−1だけが第1の電池に作用して第1の電池を方向Bへ押し出すが、固定部3aが限界位置P2を越えて第2の電池寄りの位置にある場合には、把持部をA方向へ引き出したときに第2の電池を支持する巻き付き部分3b−2までが引張力を受けて第2の電池を押し出すこととなり、詰まりが生じる原因を作ることとなる。
この際、リボン3の固定部3aを配置する内壁位置を図1(a)(b)に示した位置(2つの電池B1、B2の中間位置)よりも第1の電池B1寄りの内壁に配置すれば、リボン第2の電池B2をリボンによってすくい上げる際に電池B2に作用する力が強くなり、電池B2を更に大きく上方へ押し出すことが可能となり、取出しが容易となる。図2はリボンの固定部3aを第1の電池B1寄りの内壁に配置した例を示している。図2において、リボン固定範囲は、第2の電池B2の外周が内壁と接する位置(限界位置P2)から取出し口13に近い内壁の端縁近傍の限界位置P1までの間である。この範囲内にリボンの固定部3aを固定することにより上記の如き本発明特有の効果を得ることができる。
即ち、リボンの固定部3aを配置する収納空所11の内壁位置は、電池ケース2の構造や電池ケース周辺の外形状等によって様々な制約を受けるが、図1で示した位置、即ち第1の電池B1と第2の電池B2のほぼ中間に相当する内壁(限界位置P2から位置P2’までの範囲)から、図2に示した電池B1の側方位置(取出し口13寄りの内壁、限界位置P1)の範囲内であれば、リボン3の把持部を引っ張るだけで、全ての電池を順次スムーズ且つ容易に取出すことができる。なお、中間位置とは、図2のP2からP2’の範囲であり、この中間位置範囲を図面左方に超えた限界位置P1までの範囲であれば、固定部3aを固定することできる。
なお、電池ケース2内に収納する電池の個数は、2本以上であっても、2本の場合と同様にリボン11を配回すことにより、同様に第1の電池から順次スムーズに取出すことが可能となる。即ち、図3は電池ケース内に3本の電池B1、B2、B3を横方向に並列状態に配置した構成例を示している。電池の取出し方向は、電池の軸方向と直交する径方向である。なお、図1と同一部分には同一符号を付して説明する。
【0009】
リボンの固定部3aは、この例では、収納空所11の底部11a上の、最初に取出す第1の電池B1と、隣接配置された第2の電池B2との間に相当する位置に固定され、リボンの巻き付き部3bは、少なくとも最初に取出す電池B1の外周の半周以上に巻き付くように構成されている。
更に、リボンの巻き付き部3bは、固定部3aに近い部分から収納空所内壁に沿うように添設されて、最初に取出す電池B1以外の全ての電池B2、B3の外周(ほぼ全周)を反時計回りに包囲するように巻き付き、更に最初に取出す電池B1とその隣の電池B2との間隙に上側から入り込んでから最初に取出す電池B1の外周を時計廻りに包囲するように、全体としてS字状に巻き付いて、電池取出し口13内に把持部3cが位置するように配設される。
このため、図1(b)と同様に、リボン3の把持部3cを指等によって把持して(つまんで)、矢印で示す電池の軸方向と直交する方向Aへ引き出すことにより、真っ先に電池B1だけを矢印Bで示す径方向へ取出すことができる。このとき、電池B2、B3はリボン3によって固定され殆ど動かない(第1の電池の取出しに影響がない程度の挙動は許容範囲)。電池B1が取り外された後、さらにリボンを引くと電池B2と電池B3が順次リボンによって引き出され、3本の電池とも容易に取り外すことができる。
このように本発明のようにリボンを配回すことにより、電池が3本、或いはそれ以上の場合であっても、第1の電池B1が最初に取出されると、電池ケース2内にスペース的な余裕が確保され、残りの他の電池をリボンによって簡単に引き出すことができるようになる。
この場合も、リボンの固定部3aを固定する位置は、図3に示した如き第1と第2の電池の中間位置から、第1の電池B1の側方に位置する内壁までの範囲を任意に選定可能である。
【0010】
【発明の効果】
以上のように本発明によれば、円筒状の電池を複数個並列に収納する電池ケースと、電池ケース内に一端を固定されて電池取出し時に端部を引き出すことによって電池を電池ケースの狭い取出し口から取出すように構成したリボンと、を備えた電池室の構造において、リボンの固定位置、及び配回し構造を工夫することによって、狭い取出し口から順序よく電池を取出すことができる。
即ち、請求項1の発明によれば、取出し口に最も近い最初に取出す第1の電池の外周にリボンを巻きつけることで、他の電池の影響を受けずに最初に取出す電池を簡単に取り外すことができ、その後の電池も容易に外すことができるようになる。
請求項2の発明によれば、最初に取出す電池と他の電池の外周にS字状にリボンを巻きつけることで、最初に取出す電池を容易に取り外すことができるばかりでなく、他の電池もリボンにより容易に取出すことができるようになる。
請求項3の発明によれば、リボンを固定する位置が広い範囲にあるため、電池ケースの形状や、外形形状に多くの自由度を持たせることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in the structure of a battery chamber for storing dry batteries in a portable device such as a camera and a radio, and more particularly, to a narrow outlet in a battery chamber for storing two or more cylindrical batteries such as AA batteries in parallel. The present invention relates to a structure of a battery chamber in which batteries can be taken out from the battery compartment in order.
[0002]
[Prior art]
In portable devices such as cameras and radios that use two or more cylindrical dry batteries, such as AA batteries, in parallel in a battery compartment and use them as a power source, conventionally, when removing batteries from the battery compartment, the end of the battery is used. Had to be taken out with hooks. However, when the spring-shaped terminal provided in the battery chamber strongly holds the electrode at the battery end, or when there is a small gap between the battery end and the wall of the battery chamber, the battery terminal may be clawed or the like. There was a drawback that it was not easy to hook the part out.
For this reason, conventionally, as shown in FIGS. 4A and 4B, a battery chamber 100 is composed of a battery case 101 and a ribbon 102, and a ribbon 102 having one end 102a fixed to the inner wall of the battery case 101 is attached to the inner wall. When the batteries 105a, 105b are to be stored, the batteries 105a, 105b, 105c are arranged in parallel on the ribbon when the batteries 105a, 105b are stored, and when the batteries are taken out, the other end 102b of the ribbon 102 is picked up and pulled up. The battery is taken out in the radial direction from 103.
By the way, in the design of a portable device, the external shape of the device is often formed into a curved surface along the shape of a cylindrical battery to be stored. In such a case, the width W1 of the battery outlet 103 may be designed to be smaller than the sum of the diameters d1 of all the batteries 105 to be stored. In this case, when storing or removing the batteries from the outlet 103, if the order of storing or removing the batteries is incorrect, the batteries may not be able to be stored or removed.
Conventionally, in order to cope with such a problem, the ribbon 102 is laid under all the batteries 105 as shown in FIG. 4, and the other end 102b of the ribbon is pulled out from the battery 105a to be taken out first. However, in this method, as shown in FIGS. 4A and 4B, all the batteries start to move at the same time, the batteries collide with each other, and the outlet 103 is closed. could not.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above, and has a battery case for accommodating a plurality of cylindrical batteries in parallel, and a battery provided in the battery case and having an end portion withdrawn when the battery is taken out, thereby connecting the battery to the battery case. In the structure of the battery compartment, which has a ribbon configured to be taken out from the narrow outlet, and by devising the fixing position of the ribbon and the arrangement structure, the batteries can be successively clogged in order from the narrower outlet, without causing clogging. It is an object to provide a structure of a battery chamber configured to be able to be taken out.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention of claim 1 provides a storage space for accommodating a plurality of cylindrical batteries in parallel, and a storage space formed by opening a part of a peripheral wall forming the storage space. A battery case, comprising: a battery outlet that allows radial extraction of batteries in the station one by one; and a width of the battery outlet is set to be smaller than a total diameter of all batteries that can be stored in the storage space. A battery having a fixed portion at one end fixed to the inner wall of the storage space, an intermediate winding portion wound around the outer periphery of all the stored batteries, and a grip portion at the other end provided so as to be able to be pulled out from the battery outlet. And a take-out ribbon, wherein the ribbon is configured to be wound around half or more of the outer circumference of the battery at the position where the battery is first taken out in the storage space.
When a battery outlet for battery attachment / detachment is formed in the peripheral wall of the storage space for accommodating a plurality of cylindrical batteries in parallel, and the width of the outlet is too small to allow two batteries to be taken out at the same time, the storage space A configuration is adopted in which a ribbon is arranged along the inner wall of the place, the battery is supported on the ribbon when the battery is stored, and the battery is taken out by taking out one end of the ribbon from the outlet when taking out the battery. In this case, if two or more batteries are simultaneously moved toward the outlet by pulling the ribbon, the narrow outlet becomes jammed, making it difficult to take out.
Therefore, in the present invention, a procedure was devised in which the ribbon is wound around the battery so that only the battery closest to the outlet when the ribbon is pulled is drawn out first, and then the adjacent batteries are pulled out sequentially. Specifically, the winding portion near the free-end-shaped end portion (grip portion) of the ribbon is wound around at least half the circumference of the outer periphery of the first battery near the outlet, so that the grip portion of the ribbon is removed from the outlet. When pulled outward, the first battery is pulled out first, and at this time, the remaining batteries such as the adjacent batteries do not behave at all. For this reason, a plurality of batteries do not collide with each other at the narrow outlet to cause clogging. By displaying such a ribbon arrangement method on the ribbon itself or outside the battery compartment and instructing how to set the battery, the operator can definitely easily set the ribbon and the battery. It is possible to take out all the batteries smoothly from the batteries near the outlet only by pulling the ribbon when taking out the batteries.
[0005]
According to a second aspect of the present invention, in the first aspect, the battery outlet is provided so as to be shifted toward a position facing the first battery to be taken out with respect to a battery arrangement direction in the storage space, The ribbon is attached along the inner wall of the storage space from the winding portion near the fixing portion and is wound so as to surround the outer periphery of the battery other than the battery to be taken out first, and further the battery to be taken out first and After being inserted between adjacent batteries, the battery is wound in an S shape so as to surround the outer periphery of the first battery to be taken out, and is disposed so that the grip portion is located at the battery outlet. .
The wrapped portion of the ribbon is arranged so that the portion closer to the fixed portion of the ribbon surrounds the outer periphery of the battery (the battery after the second battery) to be taken out later, and the folded back portion is taken out first. An S-shape is formed as a whole by being inserted between the first battery and the second battery and then wrapped around the outer periphery of the first battery. For this reason, when the grip portion of the ribbon is pulled out, only the wrapped portion supporting the first battery is pulled out, and only the first battery supported by the wrapped portion is taken out from the outlet. The remaining batteries supported by the remaining portion of the S-shaped ribbon wrap are substantially stationary without being pulled out by the ribbon. After the first battery is removed, the ribbon is continuously pulled out, so that the wrapped portion supporting the batteries subsequent to the second battery receives a tensile force, so that the second battery starts operating for the first time and is removed from the outlet. You. Further, when the third and fourth batteries are arranged in parallel, they are taken out sequentially and in order, and no clogging occurs.
According to the third aspect of the present invention, in the first or second aspect, the first fixing portion of the ribbon includes the first battery to be taken out from an inner wall portion of a storage space corresponding to an intermediate portion between the battery to be taken out first and a battery adjacent thereto. Is fixed in the range of the inner wall portion corresponding to the side of the inner wall portion.
When the position for fixing the fixing portion of the ribbon to the inner wall of the storage space is out of the above range, for example, when the position is closer to the second battery than the intermediate position between the first and second batteries, Even if the ribbon is arranged in an S-shape, when the end of the ribbon is pulled out, a tensile force acts on the winding portion supporting the second battery, and not only the first battery, but also the second battery. Even the battery is pulled in the pull-out direction. Therefore, one limit position of the range in which the fixing portion of the ribbon is arranged is an intermediate position between the first and second batteries. The other limit position of the range in which the fixing portion is arranged is a position of an inner wall corresponding to a side of the first battery. By doing so, the force acting on the second battery when the ribbon is further pulled after the first battery is taken out increases, and the batteries subsequent to the second battery are largely moved to take out the outlet. It can be pushed outward.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
1A and 1B are cross-sectional views showing the structure of a battery chamber according to one embodiment of the present invention.
The battery chamber 1 forms a part of a portable device (not shown), and includes a battery case 2 for accommodating a plurality of cylindrical batteries B1 and B2 so that the battery can be freely inserted and removed, and a ribbon disposed in the battery case 2. 3 is provided.
As shown in FIGS. 1 (a) and 1 (b), the battery case 2 forms a storage space 11 for storing a plurality of cylindrical batteries B1 and B2 close to each other in a parallel state, and the storage space 11 is formed. A battery outlet which is formed in a part of the peripheral wall 12 to be opened so that the first and second batteries B1 and B2 in the storage space 11 can be taken out one by one in a radial direction (a direction orthogonal to the axial direction of the battery). 13 is provided. The battery outlet 13 is formed in the upper wall of the peripheral wall 12 of the storage space, and the opening width W1 of the battery outlet 13 is the sum of the diameters d1 of all the batteries that can be stored in the storage space 11. It is set to be narrower than the dimensions given. In this embodiment, since the first and second batteries B1 and B2 are arranged side by side in the horizontal direction, the storage space 11 has a horizontally long shape, and the battery outlet 13 is opened at the upper part of the peripheral wall 12 thereof. The bottom portion 11a of the storage space is formed below and opposite to the battery outlet 13. The size of the battery outlet 13 in the depth direction is set slightly larger than the axial length of the battery so that the battery can be taken out. The opening width W1 of the battery outlet 13 is set smaller than the total size of the diameters d1 of all the batteries so that all the stored batteries B1 and B2 cannot be taken out at once for reasons such as layout. Further, the battery outlet 13 is arranged so as to be displaced closer to the battery B1 to be taken out first than the center in the width direction of the bottom 11a of the storage space. For this reason, the second battery B2 located on the back side cannot be taken out first by a pull-out operation of the ribbon 3 described later, and the first battery B1 near the take-out port 13 is always taken out first. . Moreover, in the process of removing the first battery from the outlet, the second battery is not moved by the ribbon, and the two batteries are not clogged at the outlet.
[0007]
As shown in FIG. 1 (a), the ribbon 3 is a battery take-out means which is made of, for example, a flexible insulating sheet having a narrow band shape and a width capable of holding the battery stably. The fixing portion 3a at one end of the ribbon 3 is fixed to the inner wall (bottom portion 11a) of the storage space 11, and the intermediate winding portion 3b is wound in an S shape around the outer periphery of the stored batteries B1 and B2, and the other end. Is provided so as to be able to be pulled out from the battery outlet 13.
In this example, the fixing portion 3a of the ribbon is located at a position (intermediate position) on the bottom 11a of the storage space 11 corresponding to a position between the first battery B1 to be taken out first and the adjacent second battery B2. The ribbon winding portion 3b is fixed so as to wind around at least a half of the outer circumference of the battery B1 to be taken out first. Therefore, when the grip portion 3c is pulled in the removal direction A, only the first battery B1 moves in the same direction, and the second battery B2 is almost stationary.
More specifically, the ribbon winding portion 3b is provided along the inner wall of the storage space from a portion near the fixing portion 3a, and the outer periphery (almost the entire periphery) of the battery B2 other than the battery B1 to be taken out first. Is wound so as to surround the battery B1 to be taken out counterclockwise, and further enters the gap between the battery B1 to be taken out first and the battery B2 next to the battery B1 from above, and then surrounds the outer periphery of the battery B1 to be taken out clockwise as a whole. It is wound so as to form an S-shape, and is disposed so that the grip portion 3c is located in the battery outlet 13.
For this reason, as shown in FIG. 1B, the grip portion 3c of the ribbon 3 is gripped (pinched) with a finger or the like, and pulled out in the direction A perpendicular to the axial direction of the battery indicated by the arrow, so that it is first. Only the battery B1 can be taken out in the direction of arrow B. At this time, the battery B2 is fixed by the ribbon and hardly moves. When the ribbon is further pulled after the battery B1 is removed, the battery B2 is pulled out by the ribbon, and both batteries can be easily removed.

When the position where the fixing portion 3a is fixed to the inner wall is located at a position (for example, the position 102a shown in FIG. 4) that is displaced more toward the second battery than the illustrated intermediate position, the first ribbon is pulled. The second battery is also sequentially pulled by the ribbon substantially in conjunction with the operation of taking out the battery, and there is a possibility that both batteries may be clogged at the narrow outlet. That is, as long as the fixing portion 3a is in the intermediate position as shown in FIG. 1, when the grip portion 3c is pulled out in the direction A, only the winding portion 3b-1 supporting the first battery acts on the first battery. The first battery is pushed out in the direction B, but if the fixing portion 3a is beyond the limit position P2 and is closer to the second battery, the second battery is pulled out when the grip portion is pulled out in the direction A. The supporting part 3b-2 receives the tensile force and pushes out the second battery, which causes a clogging.
At this time, the inner wall position where the fixing portion 3a of the ribbon 3 is arranged is arranged on the inner wall closer to the first battery B1 than the position shown in FIGS. 1A and 1B (the intermediate position between the two batteries B1 and B2). Then, the force acting on the battery B2 when the ribbon second battery B2 is scooped up by the ribbon is increased, and the battery B2 can be pushed further upward, thereby facilitating removal. FIG. 2 shows an example in which the fixing portion 3a of the ribbon is arranged on the inner wall near the first battery B1. In FIG. 2, the ribbon fixing range is from the position where the outer periphery of the second battery B2 contacts the inner wall (limit position P2) to the limit position P1 near the edge of the inner wall near the outlet 13. By fixing the fixing portion 3a of the ribbon within this range, the above-described effects unique to the present invention can be obtained.
In other words, the position of the inner wall of the storage space 11 where the ribbon fixing portion 3a is disposed is subject to various restrictions depending on the structure of the battery case 2, the outer shape around the battery case, and the like, but the position shown in FIG. From the inner wall (the range from the limit position P2 to the position P2 ') corresponding to a substantially intermediate position between the battery B1 and the second battery B2, the lateral position of the battery B1 shown in FIG. Within the range of the position P1), all the batteries can be sequentially and smoothly taken out simply by pulling the grip portion of the ribbon 3. Note that the intermediate position is a range from P2 to P2 'in FIG. 2, and the fixing portion 3a can be fixed as long as it is a range from the intermediate position range to the limit position P1 which is beyond the left side of the drawing.
In addition, even if the number of batteries stored in the battery case 2 is two or more, by arranging the ribbon 11 in the same manner as in the case of two batteries, it is possible to sequentially and smoothly take out the batteries from the first battery. It becomes possible. That is, FIG. 3 shows a configuration example in which three batteries B1, B2, and B3 are arranged in a lateral direction in a battery case. The direction of taking out the battery is a radial direction orthogonal to the axial direction of the battery. Note that the same parts as those in FIG.
[0009]
In this example, the fixing portion 3a of the ribbon is fixed at a position on the bottom 11a of the storage space 11 corresponding to a position between the first battery B1 to be taken out first and the second battery B2 disposed adjacent to the first battery B1. The ribbon winding portion 3b is configured to wind around at least a half of the outer circumference of the battery B1 to be taken out first.
Further, the wrapped portion 3b of the ribbon is provided along the inner wall of the storage space from a portion near the fixing portion 3a, and covers the outer circumference (almost the entire circumference) of all the batteries B2 and B3 except the battery B1 to be taken out first. Wrap so as to surround the battery B1 to be taken out counterclockwise, enter the gap between the battery B1 to be taken out first and the battery B2 next to it from the upper side, and then surround the outer periphery of the battery B1 taken out first clockwise, so that S It is arranged so that it is wound in the shape of a letter and the grip portion 3c is located in the battery outlet 13.
For this reason, similarly to FIG. 1B, the grip portion 3c of the ribbon 3 is gripped (pinched) with a finger or the like and pulled out in a direction A perpendicular to the axial direction of the battery indicated by an arrow, so that the battery Only B1 can be taken out in the radial direction indicated by arrow B. At this time, the batteries B2 and B3 are fixed by the ribbon 3 and hardly move (a behavior that does not affect the removal of the first battery is an allowable range). When the ribbon is further pulled after the battery B1 is removed, the batteries B2 and B3 are sequentially pulled out by the ribbon, and all three batteries can be easily removed.
By arranging the ribbon as in the present invention as described above, even if the number of batteries is three or more, when the first battery B1 is first removed, the space in the battery case 2 is reduced. And the remaining batteries can be easily pulled out by the ribbon.
Also in this case, the position where the fixing portion 3a of the ribbon is fixed may be any range from the intermediate position between the first and second batteries as shown in FIG. 3 to the inner wall located on the side of the first battery B1. Can be selected.

【The invention's effect】
As described above, according to the present invention, a battery case accommodating a plurality of cylindrical batteries in parallel, and one end is fixed in the battery case and the end is pulled out at the time of taking out the battery, so that the battery is taken out narrowly from the battery case. In the structure of the battery compartment provided with the ribbon configured to be taken out from the mouth, by devising the fixing position of the ribbon and the arrangement structure, the batteries can be taken out from the narrow outlet in order.
That is, according to the first aspect of the present invention, by winding the ribbon around the outer periphery of the first battery to be taken first closest to the outlet, the battery to be taken out first can be easily removed without being affected by other batteries. The battery can be easily removed thereafter.
According to the invention of claim 2, by winding the ribbon in an S shape around the outer periphery of the battery to be taken out first and the other battery, not only the battery to be taken out first can be easily removed, but also other batteries can be removed. The ribbon allows easier removal.
According to the third aspect of the present invention, since the position where the ribbon is fixed is in a wide range, the battery case can have a large degree of freedom in the shape and the external shape.
