Description

本発明は、取手付き鉛蓄電池およびこれの取手接続構造に関するものである。   The present invention relates to a lead-acid battery with a handle and a handle connection structure thereof.

自動車のセルスタータや駆動源（補助電源の場合も含む）として需要の大きい鉛蓄電池は、主材料が鉛であるため比重が大きい。よって物流をはじめ販売にいたる流通段階、さらには機器や車両への搭載における荷扱いの利便性も、重要な機能のひとつになっている。この利便性への要望に応えるべく、持ち運びや交換作業に適した取手付き鉛蓄電池が開発されてきた。とりわけ日常的に多くの鉛蓄電池を取り扱う物流・流通業者やカーショップ、ホームセンターなどの量販店が取手付き鉛蓄電池を所望する場合が多いため、需要も堅調である。   Lead-acid batteries that are in great demand as automobile cell starters and drive sources (including auxiliary power supplies) have a high specific gravity because the main material is lead. Therefore, the distribution stage from distribution to sales, as well as the convenience of cargo handling in equipment and vehicles, are also important functions. In order to meet this demand for convenience, lead-acid batteries with handles suitable for carrying and replacement have been developed. In particular, logistics and distribution companies that handle many lead storage batteries on a daily basis, and mass retailers such as car shops and home centers often desire lead storage batteries with handles, so demand is also firm.

補修用をはじめとした自動車用鉛蓄電池は、段ボール等の外装箱に梱包された状態で流通および販売される。すなわち外装箱に梱包された状態でも、外装箱から取り出すときでも、さらには取り出した後でも、取手による吊り下げができることが望ましい。この取手が流通・販売・作業時に外れて鉛蓄電池が落下すると、鉛蓄電池自体が破損するばかりでなく、人体に損傷を来たす虞があるので、取手の装着は頑強である必要がある。   Lead-acid batteries for automobiles including those for repair are distributed and sold in a state of being packed in an outer box such as cardboard. That is, it is desirable that the handle can be hung even when it is packed in the outer box, when it is taken out from the outer box, or even after it is taken out. If this handle comes off during distribution, sales or work and the lead acid battery falls, not only will the lead acid battery itself be damaged, but the human body may be damaged.

一方、鉛蓄電池を車載した後で、メンテナンスとしての補水の際などに、取手が邪魔になるので、鉛蓄電池から取手が容易に取り外せることも重要である。   On the other hand, after the lead-acid battery is mounted on the vehicle, the handle gets in the way when water is replenished as maintenance, so it is also important that the handle can be easily removed from the lead-acid battery.

上述した２つの要望（頑強な装着と取り外しの容易性）を満たすべく、蓄電池から取手をワンタッチで着脱できる接続構造が開示されている（例えば、特許文献１）。但しこの構造では、上方から誤って取手に荷重を掛けた際に、取手の係合端部が電槽の係止具から外れやすくなるという課題がある。そこで特許文献２のように、側壁の外方へと折り曲がった屈曲部を取手に設け、ベルト部と膨頭部を有する脚部の終端と接続した幅広の終端部を係合端部に設け、側壁の外方へ突出させ先端を対向させた一対の抜け止め片と溝を係止具に設け、抜け止め片と側壁で囲まれた空間部に脚部を嵌入して膨頭部の下面を抜け止め片の上縁と対向させつつ終端部の上縁を一対の抜け止め片の下縁に当接させることで取手を電槽に固定し、膨頭部を幅方向の内方へ押圧しかつ取手を下方に引くことで、溝からベルト部を内外に抜き差しする構造が提案されている。   In order to satisfy the above-described two demands (sturdy attachment and ease of removal), a connection structure in which a handle can be attached and detached from the storage battery with one touch is disclosed (for example, Patent Document 1). However, with this structure, when a load is applied to the handle by mistake from above, there is a problem in that the engagement end portion of the handle is easily detached from the battery case locking tool. Therefore, as in Patent Document 2, a bent portion bent outward from the side wall is provided in the handle, and a wide end portion connected to the end portion of the leg portion having the belt portion and the swelling head portion is provided in the engaging end portion. A pair of retaining pieces and grooves that protrude outwardly from the side wall and are opposed to each other at the front end are provided in the locking device, and legs are fitted into the space surrounded by the retaining pieces and the side wall to The handle is fixed to the battery case by bringing the upper edge of the terminal part into contact with the lower edge of the pair of retaining pieces while facing the upper edge of the retaining piece, and the expansion head is pressed inward in the width direction. However, a structure has been proposed in which the belt portion is inserted into and removed from the groove by pulling the handle downward.

FIG. 3A shows the structure after the handle is connected, FIG. 3A shows the handle, and FIG. 3B shows an enlarged view of the engaging end. In order to describe in detail the internal configuration of the lead-acid storage battery with handle, FIGS. 1 (a) and 2 (a) and 2 (b) are shown in a partially invisible form. Further, the structure and effects of the present invention will be described in detail by combining the handle connection structure of the present invention and the main part of the lead-acid battery with the handle shown in FIG.

取手付き鉛蓄電池１は、正極２ａと負極２ｂとセパレータ２ｃとからなる極板群２と、複数の極板群２を収納するための複数のセル室（２枚の壁３ａの間で構成）を有する電槽３と、電解液（図示せず）と、複数の極板群２を直列および／あるいは並列に接続する接続部品４と、正極端子５ａと負極端子５ｂと液口栓５ｃとを備えかつ電槽３の開口上面と接合される蓋５と、電槽３を吊り下げるための取手６とからなる。   A lead-acid battery 1 with a handle includes an electrode plate group 2 composed of a positive electrode 2a, a negative electrode 2b, and a separator 2c, and a plurality of cell chambers for housing a plurality of electrode plate groups 2 (configured between two walls 3a). A battery case 3, an electrolyte solution (not shown), a connecting part 4 for connecting a plurality of electrode plate groups 2 in series and / or in parallel, a positive terminal 5a, a negative terminal 5b, and a liquid plug 5c. The lid 5 is provided and joined to the upper surface of the opening of the battery case 3, and the handle 6 for hanging the battery case 3.

正極２ａは、鉛または鉛合金からなる格子と二酸化鉛とからなる。負極２ｂは、鉛または鉛合金からなる格子と海綿状鉛とからなる。セパレータ２ｃは、ガラス繊維や諸々の樹脂などからなる。これら複数の正極２ａと負極２ｂとを、セパレータ２ｃを介して交互に対峙させることで、極板群２が構成される。   The positive electrode 2a is made of a lattice made of lead or a lead alloy and lead dioxide. The negative electrode 2b is made of a lattice made of lead or a lead alloy and spongy lead. The separator 2c is made of glass fiber or various resins. The electrode plate group 2 is configured by alternately facing the positive electrodes 2a and the negative electrodes 2b via the separators 2c.

電解液は、硫酸を主成分とする水溶液からなる。また接続部品４、正極端子５ａおよび負極端子５ｂは、鉛または鉛合金からなる。   The electrolytic solution is an aqueous solution containing sulfuric acid as a main component. Moreover, the connection component 4, the positive electrode terminal 5a, and the negative electrode terminal 5b consist of lead or a lead alloy.

液口栓５ｃはポリプロピレンなどの樹脂やエチレンプロピレンジエンゴムなどのゴム材料からなり、メンテナンスとしての補水（過充電に伴う加水分解に相応する水分の補給）の際に取り外すことができる。さらに電槽３および蓋５は、ポリプロピレンやアクリロニトリル−ブタジエン−スチレンなどの樹脂からなる。   The liquid stopper 5c is made of a resin such as polypropylene or a rubber material such as ethylene propylene diene rubber, and can be removed at the time of water replenishment (replenishment of water corresponding to hydrolysis accompanying overcharge) as maintenance. Furthermore, the battery case 3 and the lid 5 are made of a resin such as polypropylene or acrylonitrile-butadiene-styrene.

電槽３の相対向する側壁３ｂの外面には、それぞれ係止具７を設けている。係止具７は、側壁３ｂの外方へ平行に突出させかつ先端を相対向するように折り曲げられた一対の抜け止め片７ａと、一対の抜け止め片７ａの間で構成される溝７ｂとからなる。   Locking tools 7 are provided on the outer surfaces of the opposite side walls 3b of the battery case 3, respectively. The locking tool 7 has a pair of retaining pieces 7a that are projected in parallel outward from the side wall 3b and bent so that their tips are opposed to each other, and a groove 7b that is formed between the pair of retaining pieces 7a. Consists of.

取手６は、ベルト部８の両端に係合端部９を設けた形状とし、取手６の一部には外方に向けて折り曲げられた屈曲部１０を設けている。係合端部９は、側壁３ｂの外方に突出した膨頭部９ｂを屈曲部１０より上方に有する一対の脚部９ａと、ベルト部８およびこれの両隣に配置した一対の脚部９ａのそれぞれの終端と接続しつつ幅方向に突出した終端部９ｄと、ベルト部８と略平行となるように膨頭部９ｂと連接しつつ上方に突出した棒状部９ｅとからなる。   The handle 6 has a shape in which engagement end portions 9 are provided at both ends of the belt portion 8, and a bent portion 10 that is bent outward is provided in a part of the handle 6. The engagement end portion 9 includes a pair of leg portions 9a having a bulging head portion 9b protruding outward from the side wall 3b above the bent portion 10, a belt portion 8 and a pair of leg portions 9a disposed on both sides thereof. The end portion 9d protrudes in the width direction while being connected to each end portion, and the rod-like portion 9e protruding upward while being connected to the expanding head portion 9b so as to be substantially parallel to the belt portion 8.

図１〜３の構成において、取手付き鉛蓄電池１を載置した後、膨頭部９ｂを幅方向の内方へ押圧しつつ取手を下方に引けば、後々の補水（液口栓５ｃを開けて行う）を考えて取手６を外すことができる。しかし往々にして、取手付き鉛蓄電池１はボンネット等の狭い車内スペースの中に載置されるので、指先で膨頭部９ｂを抓んで幅方向の内方へ押圧することは、非常に困難である。   In the configuration of FIGS. 1 to 3, after placing the lead-acid battery 1 with a handle, if the handle is pulled downward while pressing the expansion head 9b inward in the width direction, the subsequent water replenishment (the liquid spout 5c is opened). The handle 6 can be removed. However, since the lead-acid battery 1 with a handle is often placed in a narrow interior space such as a bonnet, it is very difficult to pinch the swelling head 9b with a fingertip and press it inward in the width direction. is there.

そこでベルト部８と略平行となるように膨頭部９ｂと連接させた棒状部９ｅを設けつつ、この棒状部９ｅを上方に突出させれば、図４に示すように、作業者が棒状部９ｅの上端を抓んで幅方向の内方（矢印方向）へ押圧することで膨頭部９ｂもまた幅方向の内方へ押圧されることになるので、取手６を下方に引けば、溝７ｂからベルト部８を容易に内外に抜き差しできるようになる。よって狭いスペースの中でも、取手付き鉛蓄電池１から無理なく取手６を外すことができるようになる。   Therefore, if a rod-like portion 9e connected to the swelling head 9b is provided so as to be substantially parallel to the belt portion 8 and this rod-like portion 9e is projected upward, as shown in FIG. By holding the upper end of 9e and pressing it inward in the width direction (arrow direction), the bulging head 9b is also pressed inward in the width direction. Therefore, if the handle 6 is pulled downward, the groove 7b The belt portion 8 can be easily inserted and removed from the inside. Therefore, the handle 6 can be removed from the lead-acid battery 1 with a handle without difficulty in a narrow space.

なお棒状部９ｅの上端を蓋５の上面よりも上方に突出させれば、作業箇所が蓋５の上面になって、ベルト部８の抜き差しがさらに容易になるので好ましい。   Note that it is preferable that the upper end of the rod-shaped portion 9e is protruded upward from the upper surface of the lid 5 because the work location becomes the upper surface of the lid 5 and the belt portion 8 can be easily inserted and removed.

ここで抜け止め片７ａと側壁３ｂで囲まれた空間部に脚部９ａを嵌入し、膨頭部９ｂの下面９ｃをそれぞれ抜け止め片７ａの上縁と対向させつかつ終端部９ｄの上縁を一対の抜け止め片７ａの下縁に当接させることで、取手６が電槽３蓋に固定できる。なお膨頭部９ｂが屈曲部１０より上方に設けられることで、脚部９ａの嵌入が円滑化する。   Here, the leg portion 9a is fitted into the space surrounded by the retaining piece 7a and the side wall 3b, and the lower surface 9c of the swelling head portion 9b is opposed to the upper edge of the retaining piece 7a, and the upper edge of the end portion 9d. Is brought into contact with the lower edges of the pair of retaining pieces 7a so that the handle 6 can be fixed to the battery case 3 lid. In addition, the expansion | swelling head 9b is provided above the bending part 10, and insertion of the leg part 9a becomes smooth.

取手６は通常、樹脂製である。特許文献１のように、抜け止め片と側壁で囲まれた空間部に係合片を差し込みつつ係合端部の一部を係止具の一部に当接させるだけでは、冬場などに上方から誤って取手に荷重を掛けた場合、樹脂の硬化によりベルト部が撓む前に係止具から係合端部が抜けやすくなる。そこで図１のように、抜け止め片７ａと側壁３ｂで囲まれた空間部に脚部９ａを嵌入し、膨頭部９ｂの下面９ｃを抜け止め片７ａの上縁と対向させることで、上方から誤って取手６に掛けた荷重は、膨頭部９ｂの下面９ｃが抜け止め片７ａの上縁を押さえ付ける荷重に変換され、硬化した樹脂（ベルト部８）が十分に撓むことができるので、係合端部９が係止具７から外れなくなる。このような効果を際立たせるためには、膨頭部９ｂの外側面が脚部９ａから幅方向に突出するようにして、抜け止め片７ａの上縁と対向する膨頭部９ｂの下面９ｃの面積を増やすことが好ましい。   The handle 6 is usually made of resin. Just as in Patent Document 1, the engagement piece is inserted into the space surrounded by the retaining piece and the side wall and only a part of the engagement end is brought into contact with a part of the locking tool. If a load is accidentally applied to the handle, the engaging end portion is easily removed from the locking tool before the belt portion is bent due to the hardening of the resin. Therefore, as shown in FIG. 1, the leg portion 9a is inserted into the space surrounded by the retaining piece 7a and the side wall 3b, and the lower surface 9c of the swollen head portion 9b is opposed to the upper edge of the retaining piece 7a. The load applied to the handle 6 by mistake is converted into a load in which the lower surface 9c of the swelling head 9b presses the upper edge of the retaining piece 7a, and the cured resin (belt portion 8) can be sufficiently bent. Therefore, the engagement end portion 9 cannot be detached from the locking tool 7. In order to make such an effect stand out, the outer surface of the swollen head 9b protrudes in the width direction from the leg 9a, and the lower surface 9c of the swollen head 9b facing the upper edge of the retaining piece 7a. It is preferable to increase the area.

なお図１〜３とは異なりそれぞれの係合端部９に脚部９ａを一本ずつ設けた場合に上記の効果を発現させるためには、蓋５の上面における重心に対して点対称となるように脚部９ａを設置し、取手６を接続することが望ましい。しかしながらベルト部８を挟むように脚部９ａを二本設け、抜け止め片７ａと側壁３ｂで囲まれた空間部の双方に一対の脚部９ａを嵌入させて膨頭部９ｂの下面９ｃを双方とも抜け止め片７ａの上縁と対向させる図１〜３の構成の方が、上方のみならず斜方からの荷重にも耐え得るようになるので、より好ましい。   In addition, in order to express said effect when one leg part 9a is provided in each engagement end part 9 unlike FIGS. 1-3, it becomes point-symmetric with respect to the gravity center in the upper surface of the lid | cover 5. FIG. Thus, it is desirable to install the leg portion 9a and connect the handle 6. However, two leg portions 9a are provided so as to sandwich the belt portion 8, and a pair of leg portions 9a are fitted into both the space portion surrounded by the retaining piece 7a and the side wall 3b so that the lower surface 9c of the swelling head portion 9b is both In both cases, the configuration of FIGS. 1 to 3 facing the upper edge of the retaining piece 7a is more preferable because it can withstand loads not only from above but also obliquely.

なお脚部９ａの厚みは、抜け止め片７ａと側壁３ｂで囲まれた空間部の高さより小さくする必要がある。脚部９ａの厚みが空間部の高さ以上の場合、脚部９ａの嵌入が困難になり、膨頭部９ｂを所定位置までガイドできなくなる。また膨頭部９ｂの厚みは、空間部の高さより大きくする必要がある。膨頭部９ｂの厚みが空間部の高さ以下の場合、膨頭部９ｂの下面９ｃが抜け止め片７ａの上縁と対向できなくなり、上方からの荷重によって取手６が外れやすくなる。   The thickness of the leg portion 9a needs to be smaller than the height of the space surrounded by the retaining piece 7a and the side wall 3b. When the thickness of the leg portion 9a is equal to or greater than the height of the space portion, it is difficult to insert the leg portion 9a, and the swelling head 9b cannot be guided to a predetermined position. Moreover, the thickness of the swelling head 9b needs to be larger than the height of the space portion. When the thickness of the swollen head portion 9b is equal to or less than the height of the space portion, the lower surface 9c of the swollen head portion 9b cannot be opposed to the upper edge of the retaining piece 7a, and the handle 6 is easily detached due to a load from above.

また図１〜３のように、膨頭部９ｂの外側面を先端ほど幅が細くなる円弧形状とするのが好ましい。脚部９ａを抜け止め片７ａと側壁３ｂで囲まれた空間部に嵌入する過程は、膨頭部９ｂの先端が抜け止め片７ａの内側面下端と接する第１段階と、膨頭部９ｂの外側面が抜け止め片７ａの内側面と擦れ合いながら嵌入が進行する第２段階とに分けられる。膨頭部９ｂの外側面を先端ほど幅が細くなる円弧形状とすれば、膨頭部を幅方向の内方へ押圧しなくても、第１段階から第２段階へスムーズに移行できる。   Moreover, as shown in FIGS. 1-3, it is preferable to make the outer surface of the swelling head 9b into the circular arc shape where a width | variety becomes thin as the front-end | tip. The process of fitting the leg 9a into the space surrounded by the retaining piece 7a and the side wall 3b includes a first stage in which the tip of the swelling head 9b contacts the lower end of the inner surface of the retaining piece 7a, This is divided into a second stage in which the insertion proceeds while the outer surface rubs against the inner surface of the retaining piece 7a. If the outer surface of the swollen head 9b has an arc shape whose width decreases toward the tip, it is possible to smoothly shift from the first stage to the second stage without pressing the swollen head inward in the width direction.

なお図１〜３では電槽３の側壁３ｂの外面に係止具７を設けた形態を示したが、図５のように蓋５の側壁５ｄに係止具７を設けた形態であっても、本発明の効果が得られることは言うまでもない。   In addition, although the form which provided the locking tool 7 in the outer surface of the side wall 3b of the battery case 3 was shown in FIGS. 1-3, it is the form which provided the locking tool 7 in 5 d of side walls of the lid | cover 5 like FIG. However, it goes without saying that the effects of the present invention can be obtained.

図１〜５に示すように、棒状部９ｅの上端とベルト部８とを連結する線状部９ｆを設けることで、次の２つの利点を付与できる。第１の利点は、棒状部９ｅの上端に外部応力が掛かっても、線状部９ｆが支えになって、棒状部９ｅの形状を保持する（上述した機能の損失を防ぐ）ことである。第２の利点は、線状部９ｆがバネの役目を果たすことで、一定の応力を加えないと棒状部９ｅの上端を幅方向の内方へ押圧できなくなる（偶発的な外部応力が幅方向の内方に掛かっても棒状部９ｅが幅方向の外方へ反発するので膨頭部９ｂが外れない）ことである。この第１および第２の利点を確実に現出させるためには、線状部９ｆとベルト部８との連結箇所を、線状部９ｆと棒状部９ｅとの連結箇所よりも上方とすることが望ましい。   As shown in FIGS. 1-5, the following two advantages can be provided by providing the linear part 9f which connects the upper end of the rod-shaped part 9e and the belt part 8. FIG. The first advantage is that even if an external stress is applied to the upper end of the rod-like portion 9e, the linear portion 9f is supported and maintains the shape of the rod-like portion 9e (preventing the loss of the function described above). The second advantage is that the linear portion 9f serves as a spring, and unless a constant stress is applied, the upper end of the rod-like portion 9e cannot be pressed inward in the width direction (incidental external stress is generated in the width direction). The rod-shaped portion 9e repels outward in the width direction even if it is hooked inward, so that the swelling head 9b cannot be removed). In order to make the first and second advantages appear reliably, the connecting portion between the linear portion 9f and the belt portion 8 is located above the connecting portion between the linear portion 9f and the rod-like portion 9e. Is desirable.

本発明は、制御弁式鉛蓄電池を含む各種用途・形式の鉛蓄電池に利用できるが、蓋の上面に設けた液口栓から補水する必要のある液式鉛蓄電池において、特に有用であるといえる。   The present invention can be used for various types and types of lead storage batteries including control valve type lead storage batteries, but can be said to be particularly useful in liquid lead storage batteries that need to be refilled from a liquid stopper provided on the upper surface of the lid. .
