　電池装置１００が、本体部２１０へ設けられている。 A battery device 100 is provided in the main body 210 .
　フォークリフト２００は、電池駆動のリフト機器であり、リチウムイオン電池などのような重量が小さい二次電池を利用する電池装置１００により駆動される。 The forklift 200 is a battery-driven lift device, and is driven by a battery device 100 that utilizes a light secondary battery such as a lithium ion battery.
　電池装置１００は、充電可能である複数個の電池部材１１０および１２０と、複数個の電池部材１１０および１２０を繋留めるケーブル部材１４０と、を有する。 The battery device 100 has a plurality of rechargeable battery members 110 and 120 and a cable member 140 that ties the plurality of battery members 110 and 120 together.
　電池部材１１０および１２０は、いわゆる壁掛けタイプの薄いプレート型電池部材である。電池部材１１０および１２０の各々は軽量であって、たとえば、別々の梱包で配送可能であるので、電池装置１００は、ケーブル部材１４０を利用する、現場での電池部材組付けによりフォークリフト２００の本体部２１０へ容易に取付けられる。 The battery members 110 and 120 are so-called wall-mounted type thin plate battery members. Since each of the battery members 110 and 120 is lightweight and can be delivered, for example, in separate packages, the battery device 100 can be attached to the main body of the forklift 200 by on-site battery member assembly utilizing the cable member 140. 210 is easily attached.
　ケーブル部材１４０は、フォークリフト２００の本体部２１０の上面へ掛止される。 The cable member 140 is hooked onto the upper surface of the main body 210 of the forklift 200 .
　フォークリフト２００の本体部２１０の上面は、要するに、ケーブル部材１４０が上方から掛止される、露出した面である。 The upper surface of the main body 210 of the forklift 200 is, in short, an exposed surface on which the cable member 140 is hooked from above.
　電池装置１００は、電池装置取付け治具などを利用することなしに、このようなフォークリフト２００の本体部２１０の上面へのケーブル掛止によりワンタッチ操作で容易に吊下される。 The battery device 100 can be easily hung with a one-touch operation by hooking the cable to the upper surface of the main body 210 of the forklift 200 without using a battery device mounting jig or the like.
　ケーブル部材１４０は、ロープ部材として構成されるが、たとえば、チューブ部材として構成されてもよい。 The cable member 140 is configured as a rope member, but may be configured as a tube member, for example.

　複数個の電池部材１１０および１２０は、本体部２１０の左側面へ吊下される左側の電池部材１１０、および本体部２１０の右側面へ吊下される右側の電池部材１２０である。 The plurality of battery members 110 and 120 are the left battery member 110 suspended from the left side surface of the main body part 210 and the right battery member 120 suspended from the right side surface of the main body part 210 .
　本発明者は、鉛電池規制も考慮し、フォークリフト２００のような電池駆動のリフト機器については、リチウムイオン電池などのような重量が小さい二次電池への転換が望ましいと考えている。 In consideration of lead-acid battery regulations, the inventor believes that battery-driven lift equipment such as the forklift 200 should preferably be converted to lightweight secondary batteries such as lithium-ion batteries.
　しかしながら、本発明者は、リチウムおよびコバルトの原料特性などのために、リチウムイオン電池を利用する電池部材１１０の自重はあまり大きくないことに気付いた。すなわち、本発明者は、重量が比較的に大きい荷物３００を運搬するためフォークリフト２００のようなリフト機器は鉛電池の重量に基づいて設計されているので、重量が小さい電池部材１１０の搭載にかかわらず、既存の鉛電池はいわゆるカウンターバランスのためにフォークリフト２００の本体部２１０へそのまま搭載されていることが望ましいことに気付いた。 However, the inventors have noticed that the weight of the battery member 110 using a lithium ion battery is not very large due to the raw material properties of lithium and cobalt. In other words, the present inventor believes that since the lift equipment such as the forklift 200 is designed based on the weight of the lead-acid battery in order to carry the load 300 having a relatively large weight, the battery member 110 having a small weight is mounted. First, the inventors have found that it is desirable that the existing lead-acid battery be mounted as it is on the main body 210 of the forklift 200 for so-called counterbalance.
　電池部材１１０および１２０は本体部２１０の側面へ吊下されるので、このような鉛電池は電池装置１００との干渉なしにフォークリフト２００の本体部２１０へそのまま搭載されることができる。もちろん、鉛電池がカウンターバランスを向上させるウェイトとして機能するのみならず、大掛かりなクレーン装置などが必要である、面倒な鉛電池撤去作業は不要である。 Since the battery members 110 and 120 are suspended from the side surface of the main body 210, such a lead battery can be mounted on the main body 210 of the forklift 200 as it is without interfering with the battery device 100. Of course, not only does the lead battery function as a weight to improve the counterbalance, but there is no need for troublesome lead battery removal work that requires a large-scale crane device or the like.
　なお、本発明における変形例の実施の形態の電池装置１００の模式的な平面図（その一）である図４に示されているように、複数個の電池部材１１０、１２０および１３０は、本体部２１０の左側面へ吊下される左側の電池部材１１０、本体部２１０の右側面へ吊下される右側の電池部材１２０、および本体部２１０の後側面へ吊下される後側の電池部材１３０であってもよい。 Note that as shown in FIG. 4, which is a schematic plan view (No. 1) of the battery device 100 according to the modified embodiment of the present invention, the plurality of battery members 110, 120, and 130 are connected to the main body. The left battery member 110 suspended from the left side surface of the body portion 210, the right battery member 120 suspended from the right side surface of the main body portion 210, and the rear battery member suspended from the rear side surface of the main body portion 210. 130 may be used.

　電池部材個数が増大すると、電力供給性能が向上されるのみならず、上述されたカウンターバランスも向上される。 When the number of battery members increases, not only the power supply performance is improved, but also the above-mentioned counterbalance is improved.
　車体前後方向または車体左右方向などのような所定の方向に関する対称性などを考慮し、望ましくは、車体バランスが損なわれないように、電池部材レイアウトが設計されることは言うまでもない。 It goes without saying that the battery member layout is desirably designed so that the vehicle body balance is not compromised, taking into consideration symmetry with respect to a predetermined direction such as the vehicle body longitudinal direction or the vehicle body lateral direction.
　左側の電池部材１１０は、本体部２１０の左側面へ吸着する左側の吸盤具１１１を有する。 The left battery member 110 has a left suction cup 111 that sticks to the left side of the main body 210 .
　吸盤具１１１は、吸着部の内外圧力差を利用して本体部２１０の左側面へ吸着するユニットであるが、たとえば、マグネットの吸着磁力を利用して本体部２１０の左側面へ吸着するユニットであってもよい。吸盤具１１１が有する吸着部の形状および個数、ならびに位置などは、任意である。要するに、左側の電池部材１１０の車体左右方向における動きは右側の電池部材１２０により自然に抑制され、吸盤具１１１は電池部材１１０の車体前後および上下方向における動きを補完的に抑制する役割を演じる。 The sucker 111 is a unit that uses the pressure difference between the inside and the outside of the suction portion to attract the left side of the main body 210 . There may be. The shape, number, position, and the like of the suction portions of the suction cup tool 111 are arbitrary. In short, the movement of the battery member 110 on the left side in the lateral direction of the vehicle body is naturally suppressed by the battery member 120 on the right side, and the sucker device 111 plays a role of complementarily suppressing the movement of the battery member 110 in the longitudinal and vertical directions of the vehicle body.
　右側の電池部材１２０は、本体部２１０の右側面へ吸着する右側の吸盤具１２１を有する。 The right battery member 120 has a right sucker 121 that sticks to the right side of the main body 210 .
　吸盤具１２１は、吸着部の内外圧力差を利用して本体部２１０の右側面へ吸着するユニットであるが、たとえば、マグネットの吸着磁力を利用して本体部２１０の右側面へ吸着するユニットであってもよい。吸盤具１２１が有する吸着部の形状および個数、ならびに位置などは、任意である。要するに、右側の電池部材１２０の車体左右方向における動きは左側の電池部材１１０により自然に抑制され、吸盤具１２１は電池部材１２０の車体前後および上下方向における動きを補完的に抑制する役割を演じる。 The suction cup 121 is a unit that uses the pressure difference between the inside and the outside of the suction portion to stick to the right side of the main body 210. There may be. The shape, number, position, and the like of the suction portions of the suction cup tool 121 are arbitrary. In short, the movement of the battery member 120 on the right side in the lateral direction of the vehicle body is naturally suppressed by the battery member 110 on the left side, and the sucker device 121 plays a role of suppressing the movement of the battery member 120 in the longitudinal and vertical directions of the vehicle body in a complementary manner.

　ケーブル部材１４０がチューブ部材として構成されていると、ワイヤー具１４１をチューブ中空部のスペースへ容易に挿入することができる。 When the cable member 140 is configured as a tube member, the wire tool 141 can be easily inserted into the space of the hollow portion of the tube.
　ワイヤー具１４１は、図５に示された態様においては２本のケーブル部材１４０の各々へ配索されるが、１本のケーブル部材１４０へしか配索されなくてもよい。電池直列接続または電池並列接続などのような電気的な接続に関する電池部材レイアウトなどを考慮し、ケーブル部材配索レイアウトが設計されることは言うまでもない。 Although the wire device 141 is routed to each of the two cable members 140 in the embodiment shown in FIG. 5, it may be routed to only one cable member 140. It goes without saying that the cable member routing layout is designed in consideration of the battery member layout and the like regarding electrical connections such as battery series connection or battery parallel connection.
