Description

この発明は、電動牽引車に関し、牽引操作時に安定した運転操作姿勢を維持し易くするものである。   The present invention relates to an electric tow vehicle, and facilitates maintaining a stable driving operation posture during towing operation.

バックレスト、及びアームレスト等を有した運転席を搭載した電動牽引車において、この運転席の横側に連結台車の連結フックを外し操作する操作レバーを設ける技術（例えば、特許文献１参照）が知られている。   In an electric tow vehicle equipped with a driver's seat having a backrest, an armrest, and the like, a technique is known in which an operation lever is provided on the side of the driver's seat to remove the connection hook of the connection carriage (see, for example, Patent Document 1). It has been.

特開平６−３１６２０９号公報JP-A-6-316209

電動牽引車は、工場内や倉庫等の床面のような平坦面で使用されるが、運転席に対する運転者の乗り降りの頻度の多いものであり、その運転操作の迅速性、的確性が要求される。そこで、この発明は、車体後方の牽引台車等の牽引状態、姿勢等の後方確認を行い易く、又、運転席に対する昇降を行い易くし、安全運転を維持することのできる電動牽引車を提供することを課題とする。   Electric tow trucks are used on flat surfaces such as floors in factories and warehouses, but are frequently used by drivers to get in and out of the driver's seat and require quick and accurate driving operations. Is done. Therefore, the present invention provides an electric towing vehicle that can easily confirm the towing state, posture, etc. of the towing vehicle behind the vehicle body, can easily move up and down the driver's seat, and can maintain safe driving. This is the issue.

請求項１に記載の発明は、運転席１及びこの下側のシートカバー１３下のバッテリ室４にバッテリ５を搭載し、このバッテリ室４の後側に前記バッテリ５により電動のモータ６を配置して、このモータ６によって駆動する後輪７と、前記運転席１前方のハンドル２によって操向の前輪３を配置した車体８の後部に、台車等を連結及び連結解除する連結解除装置９を設けた電動牽引車において、前記シートカバー１３の横側上部位置で、前記運転席１の座席よりも下位において、前後方向に沿うハンドステー２６と、このハンドステー２６の下側に該ハンドステー２６に対して把持回動して前記連結解除装置９の係合連結を解除する操作レバー２７を設けたことを特徴とする電動牽引車の構成とする。   According to the first aspect of the present invention, the battery 5 is mounted in the driver's seat 1 and the battery chamber 4 below the seat cover 13 on the lower side, and an electric motor 6 is disposed on the rear side of the battery chamber 4 by the battery 5. Then, a connection releasing device 9 for connecting and releasing a carriage or the like to the rear portion of the vehicle body 8 in which the rear wheel 7 driven by the motor 6 and the steering wheel 2 disposed by the handle 2 in front of the driver's seat 1 are arranged. In the provided electric tow vehicle, a hand stay 26 extending in the front-rear direction at a position on the lateral side of the seat cover 13 and below the seat of the driver's seat 1, and the hand stay 26 below the hand stay 26. The operation lever 27 for releasing the engagement and connection of the connection release device 9 by gripping and rotating is provided.

請求項１に記載の発明は、運転席１を略平坦な着座面に構成して、高いバックレストや、アームレスト等は形成しないで、しかも、運転席１の下部にはシートカバー１３で覆われたバッテリ室４や、この後側のモータ５等の配置された低い形態であるため、運転者は横前側からだけでなく、真横、後側等の乗降方向を問わないで、いずれの側からもこの運転席１をまたぐようにして乗り降りすることができる。この運転席１に対する乗降時は、運転席１の周りにハンドステー２６や操作レバー２７等が突出していないため乗降し易く、運転者が運転席１上面で着座方向を左、右へ変更してもハンドステー２６や操作レバー２７の接触抵抗を受けることがなく運転姿勢を自由に変え易い。運転者が運転席１上に着座して牽引運転中に後方の連結台車等の確認をする際は、ハンドル２の把持を放した側の片手で運転席１横下部のハンドステー２６を把持した姿勢で、上半身を後側へ回すようにして後方へ振向くため、運転姿勢を安定させることができる。そして、台車の牽引連結を外すときは、ハンドステー２６を把持する手で、このハンドステー２６の下側でハンドステー２６に沿って設けられた操作レバー２７を把持操作することによって台車の連結及び連結解除操作を行うことができ、後方の台車位置や状態等を確認しながら、安全な後向姿勢で、的確に、適正タイミングのもとに、台車連結を解除させることができる。   According to the first aspect of the present invention, the driver's seat 1 is configured to have a substantially flat seating surface, and a high backrest, an armrest or the like is not formed, and the lower portion of the driver's seat 1 is covered with a seat cover 13. Since the battery chamber 4 and the rear motor 5 and the like are arranged in a low form, the driver is not only from the front side, but from either side, regardless of the direction of getting on and off the side, rear side, etc. You can get on and off the driver's seat 1 as well. When getting on and off the driver's seat 1, it is easy to get on and off because the handstay 26, the operation lever 27, etc. do not protrude around the driver's seat 1, and the driver changes the seating direction to the left or right on the upper surface of the driver's seat 1 However, it is easy to change the driving posture freely without receiving the contact resistance of the hand stay 26 or the operating lever 27. When the driver sits on the driver's seat 1 and confirms the back-connected trolley or the like during towing operation, the driver holds the handstay 26 at the lower side of the driver's seat 1 with one hand on the side where the handle 2 is released. In the posture, the upper body is turned to the rear as if it is turned rearward, so that the driving posture can be stabilized. When removing the tow connection of the carriage, the hand holding the hand stay 26 is operated by holding the operation lever 27 provided along the hand stay 26 below the hand stay 26 to connect the carriage. The connection release operation can be performed, and the truck connection can be released accurately and at an appropriate timing in a safe backward posture while checking the position and state of the rear truck.
