【発明の属する技術分野】
本発明は、フォークリフトに関し、より詳細には、座乗型フォ−クリフトに
搭載したバッテリを収納したケ−スを覆うカバ−関する。
【0002】
【従来の技術】
各種の荷物の運搬、積み卸しに使用するフォークリフトは、近年、環境への対応の必要性からバッテリを積載した排ガスのない、低騒音の電動式のものが増えている。電動のフォ−クリフトに使用するバッテリはケ−スに収納して車体に積載し、上部カバ−及びサイドカバ−で覆っている。フォークリフトに搭載されたバッテリ−はメンテナンスのためにケ−スごと車体から取り出したり、ケ−スに収納したままで注水口を開けて補水したりする必要があり、上記上部カバ−は開閉可能に設けている。この上部カバ−は、従来より、バッテリを保護すると共に運転者がケ−スの端部でけがをしないように、ケ−スの上面全体を覆う大きさに形成され、かつ、三辺が折り曲げられて角がR形状にされた盆形状にされ、ケ−ス上端部から前側と両側の三辺で辺の折り曲げられた部分が垂れ下がり、バッテリケ−スの前側上部と両側上部を覆うように形成されている。尚、上記サイドカバ−はバッテリケ−スのサイドの保護及び車体外観をよくする目的で設けている。そして、このような従来の上部カバ−は、1枚の板からプレス成形により製造されていた。
【0003】
上記従来のバッテリの上部カバ−は、1枚板より形成しているので、大きくて重いため、開閉に大きな力が必要で、スプリング等の開閉補助手段が必要である。また、1枚の板からプレス成形により立体的に製造していたので、プレスの金型が大きくなり、成型のためのプレスの圧力を大きくしなければならず、設備費、運転費が高かった。
【0004】
【発明が解決しようとする課題】
そこで、バッテリの上部カバ−において、上部カバ−を小さくし、開閉の力を小さくし、製造のための設備費と運転費を減らすことが考えられ、従来そのための手段として以下のものがあった。
即ち、上記上部カバ−の車体幅方向の幅を小さくすると共に、上記サイドカバ−をバッテリの上部まで延長させるものである。上記サイドカバ−は、幅を小さくした上部カバ−によってできるバッテリ上部を覆うと共に、上部カバ−を受ける役目も果たす。上記の構成によると、上部カバ−を小さく軽くすることができ、バッテリのメンテナンスの際の上部カバ−の開閉が簡単にできると共に、上部カバ−のプレス金型を小さくすることができ、プレス成形する1枚当たりの面積を減らし、成形圧力を低減することができるという効果が得られる。しかしながら、上記サイドカバ−に着目すると、このサイドカバ−がバッテリ上部を一部覆うことにより、バッテリ交換時のバッテリの上部への抜き出しが行えない不具合を有し、この対策を必要とするものであった。
従って、本発明の目的は、開閉が容易にでき、製造の設備費と運転費を減らせるバッテリの上部カバ−を提供することは勿論のこと、バッテリ交換も容易に行えるバッテリのサイドカバ−提供するものである。
【0005】
【課題を解決するための手段】
そして、上記目的を達成するための手段としての本発明の請求項1のフォークリフトは、フォークリフトに搭載したバッテリケ−スを覆うための上部カバ−とサイドカバ−とからなるカバ−を備え、該上部カバ−はほぼ平板状で、しかも前記バッテリケ−スの幅より幅狭に形成され、該サイドカバ−はバッテリケ−スの側部を覆うと共に上面に張り出して上縁部を覆うように形成され、且つ、上記サイドカバ−にその後方に突出する後部位置決めピンと下方に突出する下部位置決めピンとを設けると共に、フォークリフトの車体側に上記後部位置決めピンが差し込まれる第1の穴と上記下部位置決めピンが差し込まれる第2の穴とをそれぞれ設けることにより、上記サイドカバ−が、上記後部位置決めピンを上記第1の穴に差し込むことにより車体幅方向の位置決めが行われ、上記下部位置決めピンを上記第2の穴に差し込むことにより車体前後方向の位置決めが行われることを特徴とする。そして、このようにバッテリのカバ−を構成することにより、上部カバ−を小さく軽くすることができ、プレス金型を小さくすることができて、製造の設備費と運転費を減らせ、バッテリのメンテナンスでの上部カバ−の開閉が簡単にでき、しかもサイドカバ−を容易に固定できる。
【0006】
請求項2のフォークリフトは、請求項1のフォークリフトにおいて、前記サイドカバ−は、車体部材に形成された上下方向に長穴に形成された差し込み穴に差し込むための後方に突出した後部位置決めピンを備えた。これによりサイドカバ−の車体幅方向及び車体前後方向での固定が容易に、確実にできる。
請求項3のフォークリフトは、請求項1または2のフォークリフトにおいて、前記サイドカバ−をボルトにより車体側に固着する構成とした。このように構成することによりバッテリケ−スの飛び出しを防ぐことができると共に、バッテリケ−スの固定及びバッテリのカバ−の取付が簡単にできる。
請求項4のフォークリフトは、請求項1〜3のフォークリフトにおいて、前記後部位置決めピンが差し込まれるピン差し込み穴がウエイト空洞部内に位置するピン差し込み穴形成部材に形成されている。これにより、ピン差し込み穴を隠すことができ、車の外観がすっきりし、デザイン上良好になる。また、ウエイトに穴を形成しなくてもよいから、ウエイトの形状を簡単にでき,製作コストがアップすることがない。
請求項5のフォークリフトは、請求項1〜4のフォークリフトにおいて、前記ピン差し込み穴形成部材を弾性部材とした。これにより、ピンの位置決め許容範囲を広げ、差し込みが容易にでき、ピンとピン差し込み穴との衝突により発生する騒音や、サイドカバ−と車体との接触の騒音を低減することができる。本発明で使用する弾性部材としては、ゴム製でも、プラスチック製でもよい。
【0007】
【発明の実施の形態】
以下、添付図面を参照しながら、本発明を具体化した実施の形態について説明する。ここに、図1ないし図7は本発明に係るバッテリのカバ−の1実施例を説明する図で、図1はその上部カバ−を開いた状態の一部破断した側面図、図2はその一部を破断した正面図で、図3は上部カバ−を示す図で、同図(a)は側面図、同図(b)は裏面図、図4はサイドカバ−を示す図で、同図(a)は側面図、同図(b)は車体後方から見た背面図、図5はサイドカバ−の平面図、図6はサイドカバ−の下部位置決めピンをピン差し込み穴に差し込んだ状態を示す拡大断面図、図7は本実施例のカバ−を装着したフォークリフトの側面図である。
【0008】
図1ないし図7に示すフォークリフトのバッテリのカバ−は、車体に搭載したバッテリケ−ス2の上部を覆う上部カバ−3と側面を覆うサイドカバ−4とから構成している。上部カバ−3はフォークリフトの車体に取り付けられたウエイト5の前部の横架フレ−ム部材6に蝶番により取り付けられ、回動可能にされると共に、バッテリケ−ス2の前面に設けられた係止金具7により任意に開放しないようにされている。これにより、フォークリフトが転倒した際にバッテリケ−ス内からバッテリが飛び出すのを防いでいる。サイドカバ−4は、ピンでウエイト5空洞内に位置する車体側部材とフロアプレ−ト8に位置決めされて、フレ−ム部材9にボルト止めされ、がたつかないように固定され、バッテリがフォークリフトが転倒しても飛び出したりしないようにされている。
【0009】
上部カバ−3は、図3に示すように、プレ−ト部材31からなり、前部が折り曲げられた平面状をなし、バッテリケ−ス2の車体幅方向の幅より狭く形成され、これがバッテリケ−ス2の上面を覆い、前部の折り曲げ辺が、バッテリケ−ス2の前端面上部を確実に覆うように形成されている。プレ−ト部材31の折り曲げ辺の裏面の幅方向のほぼ中央部に、上部カバ−3が不用意に開かないように、バッテリケ−ス2に設けた係止金具7に図示せざる中間部材を介して係合する係合金具32を固着している。また、プレ−ト部材31の折り曲げられて垂下する部分の裏面には、幅方向に延ばして当接金具33を固着し、折り曲げ部の強度を確保すると共に、バッテリケ−ス2の前端面に当たってがたつかないようにしている。さらに、後部には幅方向に延ばして補強板34を固着し、両端近辺に蝶番35,35を固着している。さらに、中央部には前後方向に延ばして補強金具36を固着し、座席取付用の開口37を4個所に設けている。この上部カバ−3は折曲げ部がバッテリケ−ス2前方に設けたロック機構を取り付けるだけの部分とすることにより、寸法を小さくできる。
【0010】
サイドカバ−4は、図4及び図5に示すように、プレ−ト部材41にボルト保持金具42、後部位置決めピン43,下部位置決めピン44を取付けて構成している。プレ−ト部材41は、上方に該当する上部辺と前方に該当する前方辺の2辺が折り曲げられて上部面41aと前方面41bを有する概略盆状に形成され、折り曲げられた角はRをつけて丸みを持たされている。すなわち、上部面41aと前方面41bとの角はR1の半径で丸められ、側面と上部面41aとの角はR2の半径で丸められている。
【0011】
サイドカバ−4をフォークリフトの車体に固定するためのボルトを取り付けるボルト保持金具42は、前方面41bの内側に固着されている。ボルト保持金具42はコ字形状に形成され、中央部にボルト挿通口が設けられ、脚部先端はプレ−ト41の前方面41bの内側に溶接により固着されている。なお、このボルト保持金具の脚部の先端は折り曲げて前方面41bとの接着面積を大きくし固着強度を大きくするようにしてもよい。また、プレ−ト41の前方面41bにはボルト挿通口に通すためのボルト通し穴が形成されている。図示していない車体のフレ−ムに設けられた雌ネジにボルト保持金具42のボルト挿通口を挿通したボルト10が螺着されることにより、サイドカバ−4の前方面41bが強固に固定される。
【0012】
サイドカバ−4が動かないように位置を固定するために、後部位置決めピン43,下部位置決めピン44を取付けている。後部位置決めピン43は、補強金具45をプレ−ト41の上部面41aの内側に固着し、この補強金具45に固着したピン取付金具46に固着することにより取り付けている。補強金具45とピン取付金具46はT字形状に形成されて、T字の上部面を形成するピン取付金具46に接着されている。この補強金具45の固着を強化するためにサイドカバ−4の上部面41aの内側にT字の前面部分を固着している。また、サイドカバ−4の上部面41aに対して段状をなす支持板48を上部面41aの縁部に沿って設けている。この支持板48は上部カバ−3を支持する部材である。後部位置決めピン43は、ウエイト前方に形成されたピン差し込み穴50に差し込むことによりサイドカバ−4の後方の車体幅方向の動きを規制する。
【0013】
また、サイドカバ−4の位置決めをする下部位置決めピン44は、プレ−ト41の下方縁より突出させて、前後方向で中央よりやや後方寄り内側に、取付部材47に固着されて設けられている。取付部材47はプレ−ト41の内側面に溶接等により接着されている。そして、ピン44は、車体フロア板のピン差し込み穴51に差し込まれ、サイドカバ−4の車体前後及び車体幅方向の動きを規制し、サイドカバ−4の下端が車体前後方向でずれないようにしている。上記後部位置決めピン43のピン差し込み穴50をピンが過不足なく入る幅で上下方向に長穴とし、下部位置決めピン44のピン差し込み穴51をピン断面形状に合った穴とすると車体幅方向及び車体前後方向でのサイドカバ−4の固定が強固にできる。逆に、後部位置決めピン43のピン差し込み穴50をピン断面形状に合った穴とし、下部位置決めピン44のピン差し込み穴51をピンが過不足なく入る幅で車体幅方向に長穴としても、車体幅方向及び車体前後方向でのサイドカバ−4の固定が強固にできることとなる。
【0014】
また、上記後部位置決めピン43のピン差し込み穴50を上下方向に長穴とし、上記下部位置決めピン44のピン差し込み穴51を車体幅方向に長穴としても、車体幅方向及び車体前後方向でのサイドカバ−4の動きを規制することができる。つまり、上記後部位置決めピン43のピン差し込み穴50を上下方向に長穴とすることでサイドカバ−4は車体幅方向の動きが規制され、上記下部位置決めピン44のピン差し込み穴51を車体幅方向に長穴とすることでサイドカバ−4は車体前後方向の動きが規制される。
【0015】
つまり、上記後部位置決めピン43のピン差し込み穴50の形状はピン43に合う穴、車体上下方向に長穴、車体幅方向に長穴とするとすることが考えられると共に、上記下部位置決めピン44のピン差し込み穴51の形状は、ピン44に合う穴、車体左右方向に長穴、車体前後方向に長穴とすることが考えられ、これら2つの穴を適宜組み合わせることが可能である。
【0016】
上記のように、本実施例のフォークリフトのバッテリのカバ−は、上部カバ−3をプレス成形により前方部のみが折り曲げられ、この折曲げ部がバッテリケ−スの前側に垂れ下がる形状で、バッテリケ−スの幅よりやや内側で、左右のサイドカバ−4間で、これと重ならないような寸法で形成される。従って、従来のように、1枚の板から両側と前方の3方を折り曲げる成形加工をしなくてもよくなる。その結果、一枚当たりの重量と、面積を減らせ、それに伴い、成形が容易で、製作の設備費、運転費が減らせる等の優れた効果が得られる。
【0017】
一方、サイドカバ−4は、プレス成形により前方部と,上方部とが折り曲げられ、角部が丸みを付けられて立体的に形成される。サイドカバ−4は主面がバッテリケ−スの側面を覆い、前側の折曲げ部がバッテリケ−スの前側端部を覆い、上側の折曲げ部がバッテリケ−スの上面側端部を覆う。サイドカバ−4は、プレス成形により形成されるが、その寸法は小さいことから、成形が容易で、製作の設備費、運転費が減らせる等の優れた効果が得られる。これらの効果はバッテリのカバ−全体としても、従来の一枚板から成形していたものに比べても達成できるのである。
【0018】
本発明は上記の効果が得られるのは勿論のこと、バッテリのカバ−の取付は、図7に示すように、フォークリフトに使用するには、上部カバ−3の後部を車体に蝶番で固着し、係合金具をケ−スの係止金具7に係合して上部カバ−3が不必要に開閉しないようする。サイドカバ−4は後部位置決めピン43を差し込み穴に合わせ、下部位置決めピン44を床のフロアプレ−ト8のピン差し込み穴51に合わせて下方に押してフロアプレ−ト8に密接させる。その後、ボルト保持金具42で保持したボルト10をフレ−ム部材9のねじ穴に螺着して車体側に固着する。このように、位置決めピン43、44で位置決めして1個のボルトで車体側に止めるだけであるから、それほど手間もかからずに固着することができ、バッテリケ−スの飛び出しを防ぐことができるという効果が得られる。
【0019】
なお、本発明は、上記した例に限定されるものでなく、その趣旨を変更しない範囲で変更実施できることは勿論である。たとえば、上記において、上部カバ−及びサイドカバ−の加工をすべて、1枚板をプレス加工する例で説明したが、さらに、分割して接着して構成してもよい。また、サイドカバ−の取付けを1本のボルトで行う例で説明したが、バックル等の他の連結機構としてもよく、要は、位置決めをすることによって、締結は1個所ですればよく、簡単に車体側に取り付けることができる。
【0020】
また、ピン差し込み穴は、図8及び図9に後部位置決めピン43の例で示すが、このような構成としてもよい。図8及び図9のピン差し込み穴55は、弾性体からなる差し込み穴形成部材56により形成されている。差し込み穴形成部材56は、車体側フレ−ム57にボルト58により固着された中間部材59の嵌合穴60に嵌められ、ウエイトの空洞部に位置している。この弾性部材は、ゴムから形成されたものでも、プラスチックから形成されたものでもよい。
【0021】
【発明の効果】
本願発明のバッテリのカバ−によれば、上部カバ−とサイドカバ−とから構成し、上部カバ−はほぼ平板状に形成し、サイドカバ−は少なくとも二辺を角を丸めて折り曲げた形状としたので、各部のカバ−を小さくでき、開閉の力が小さくて容易になると共に、製造のための設備費と運転費を減らすことができることは勿論のこと、サイドカバ−を二方向の位置決めピンによって位置決め固定することがきる。これにより、ボルト等の別部材からなる固定部材を必要とすることなく、サイドカバ−の着脱が容易に行える。
【0022】
また、請求項2の発明によると後部位置決めピンが、差し込まれるピン差し込み穴を長穴とすることにより、先ず、後部位置決めピンをピン差し込み穴に差し込んでサイドカバ−位置決めを行った上で、サイドカバ−を降ろして、下部位置決めピンをピン差し込み穴に差し込むことができ、サイドカバ−の位置決め及び着脱を容易とし易い。
請求項3の発明によれば、サイドカバ−をボルトにより車体側に固着するようにしたので、上記効果に加え、より確実なサイドカバ−の固定ができる。
請求項4の発明によれば、ピン差し込み穴を隠すことができ、車の外観が良好に
なる。また、ウエイトに穴を形成しなくてもよいから、ウエイトの形状を簡単にでき,製作コストがアップすることがない。
請求項5の発明によれば、ピンの位置決め許容範囲を広げ、差し込みが容易にでき、ピンとピン差し込み穴との衝突により発生する騒音や、サイドカバ−と車体との接触の騒音を低減することができる。
