Description

本発明は、被載置体を載置可能に構成された載置台を車両の開口部を通して、車両内の収納位置と車両外の地面上又はその近くの外部位置とに移動操作する移動操作手段と、前記開口部或いはその近くに位置する操作者にて操作可能に設けられた開口部側指令手段と、前記開口部側指令手段からの指令に基づいて、前記載置台を前記収納位置と前記外部位置との間で移動させるように、前記移動操作手段の作動を制御する制御手段とが設けられている車両用昇降装置に関するものである。   The present invention provides a moving operation means for moving a mounting table configured to mount a mounting body through a vehicle opening to a storage position in the vehicle and an external position on or near the ground outside the vehicle. And an opening side command means provided so as to be operable by an operator located at or near the opening, and a command from the opening side command means, the mounting table is placed in the storage position and the storage position. The present invention relates to a vehicle lifting apparatus provided with control means for controlling the operation of the moving operation means so as to move between external positions.

かかる車両用昇降装置は、被載置体を地面上と車両内との間で移載する際に用いられるものであって、従来の車両用昇降装置では、開口部に対する開閉扉を開き操作した後、開閉扉が開いた状態において操作者が開口部側指令手段を操作することにより載置台を収納位置と外部位置との間で移動させるように構成されていた（例えば、特許文献１参照。）。   Such a vehicle lifting device is used when a mounting body is transferred between the ground and the inside of a vehicle. In a conventional vehicle lifting device, an opening / closing door is opened with respect to an opening. After that, when the opening / closing door is opened, the operator operates the opening side command means to move the mounting table between the storage position and the external position (see, for example, Patent Document 1). ).

特開２０００−２３８５７１号公報JP 2000-238571 A

しかし、上記従来の構成では、車両を目的地まで走行して、その目的地において地面上の被載置体を車両内に移載させる場合、載置台が収納位置に位置し且つ開閉扉が閉じている状態であり、車両を運転していた操作者が載置台を収納位置から外部位置まで移動させるためには、運転搭乗部から開口部或いはその近くに移動し、開閉扉を開き操作した後、開口部側指令手段を操作しなければならず、載置台の移動操作が煩わしく時間がかかるものであった。   However, in the above-described conventional configuration, when the vehicle is traveled to the destination and the mounted object on the ground is transferred into the vehicle at the destination, the mounting table is located at the storage position and the open / close door is closed. In order for the operator who was driving the vehicle to move the mounting table from the storage position to the external position, after moving from the driving boarding part to or near the opening and opening the door, Therefore, the opening side command means has to be operated, and the moving operation of the mounting table is troublesome and takes time.

本発明は、上記実状に鑑みて為されたものであって、その目的は、簡単迅速に載置台の移動操作が行える車両用昇降装置を提供する点にある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle elevating device capable of easily and quickly moving a mounting table.

本願発明の車両用昇降装置は、被載置体を載置可能に構成された載置台を車両の開口部を通して、車両内の収納位置と車両外の地面上又はその近くの外部位置とに移動操作する移動操作手段と、前記開口部或いはその近くに位置する操作者にて操作可能に設けられた開口部側指令手段と、前記開口部側指令手段からの指令に基づいて、前記載置台を前記収納位置と前記外部位置との間で移動させるように、前記移動操作手段の作動を制御する制御手段とが設けられている車両用昇降装置であって、
第１特徴構成は、前記開口部に対する開閉扉を開き操作する扉操作手段と、前記車両の運転搭乗部に位置する操作者にて操作可能に設けられた運転部側指令手段とが設けられ、前記制御手段が、前記運転部側指令手段からの指令に基づいて、前記開閉扉を開き操作し且つ前記載置台を前記収納位置から前記外部位置へ移動させるように、前記移動操作手段並びに前記扉操作手段の作動を制御するように構成されている点を特徴とする。 The vehicular lifting apparatus of the present invention moves a mounting table configured to mount a mounting body through a vehicle opening to a storage position in the vehicle and an external position on or near the ground outside the vehicle. Based on a command from the moving operation means to be operated, the opening side command means that can be operated by an operator located at or near the opening, and the command from the opening side command means, A vehicle elevating device provided with control means for controlling the operation of the moving operation means so as to move between the storage position and the external position;
The first characteristic configuration is provided with a door operation means for opening and closing the opening / closing door with respect to the opening, and a driving part side command means provided so as to be operable by an operator located in the driving boarding part of the vehicle, Based on a command from the operating unit side command means, the control means opens and opens the door and moves the mounting table from the storage position to the external position so that the moving operation means and the door are operated. It is characterized by being configured to control the operation of the operating means.

すなわち、車両を目的地まで走行して、その目的地において地面上の被載置体を車両内に移載させる場合、載置台が収納位置に位置し且つ開閉扉が閉じている状態であるが、操作者は開口部或いはその近くの外部位置に移動しなくても、運転搭乗部に位置したままで運転部側指令手段を操作することにより、開閉扉を開き操作し且つ載置台が収納位置から外部位置へ移動させることができ、車両を運転していた操縦者による載置台の移動を容易に行えるので、簡単迅速に載置台の移動操作が行える車両用昇降装置を提供することができるに至った。   That is, when the vehicle is traveled to the destination and the mounted object on the ground is transferred into the vehicle at the destination, the mounting table is in the storage position and the door is closed. Even if the operator does not move to the opening or an external position near the opening, the operator operates the driving unit side command means while being in the driving boarding portion, thereby opening and closing the door, and the mounting table in the storage position. To the outside position, and the operator who was driving the vehicle can easily move the mounting table. Therefore, it is possible to provide a vehicle lifting device that can easily and quickly move the mounting table. It came.

第２特徴構成は、前記開口部の車両外方側箇所を撮像する撮像手段と、その撮像手段にて撮像された画像を表示するモニタとが備えられている点を特徴とする。   The second characteristic configuration is characterized in that imaging means for imaging the vehicle outer side portion of the opening and a monitor for displaying an image captured by the imaging means are provided.

すなわち、操作者は運転部側指令手段を操作する際に、モニタにて車両外方側箇所に開き操作される開閉扉や外部位置に移動する載置台に接当するような障害物の存否を確認することができるので、開閉扉や載置台が障害物に接当することによる損傷を未然に防ぐことができる。   In other words, when the operator operates the driving unit side command means, the operator checks whether there is an obstacle that touches the opening / closing door that is opened and operated on the outside of the vehicle or the mounting table that moves to the external position. Since it can be confirmed, it is possible to prevent damage caused by the door or the mounting table coming into contact with an obstacle.

第３特徴構成は、前記載置台上に前記被載置体が載置されているか否かを検出する存否センサが備えられ、前記制御手段が、前記存否センサの検出結果に基づいて前記載置台に被載置体が載置されている状態であると判別すると、前記運転部側指令手段の指令による前記載置台の前記収納位置から前記外部位置への移動を禁止するように、前記移動操作手段の作動を制御するように構成されている点を特徴とする。   The third characteristic configuration includes a presence / absence sensor that detects whether or not the mounting object is mounted on the mounting table, and the control unit determines whether the mounting table is based on a detection result of the presence / absence sensor. If it is determined that the mounted body is in a state of being placed on the moving unit, the movement operation is performed so as to prohibit the movement of the mounting table from the storage position to the external position according to a command from the operation unit side command unit. It is characterized in that it is configured to control the operation of the means.

すなわち、被載置体が載置されている載置台を収納位置から外部位置へ移動させる場合は、操縦者は、運転搭乗部に位置して運転部側指令手段を操作しても載置台を移動させることができないため、開口部或いはその近くに位置して開口部側指令手段を操作して載置台を移動させることとなり、被載置体の状態を近くで確認しながら開口部側指令手段を操作するので被載置体の不測の事態に対応しやすい。   That is, when moving the mounting table on which the mounted body is mounted from the storage position to the external position, the operator can position the mounting table even if the driver is positioned on the driving board and operates the driving unit side command means. Since it cannot be moved, the mounting table is moved by operating the opening side command means located at or near the opening, and the opening side command means is checked while checking the state of the mounted object. Because it is operated, it is easy to cope with the unexpected situation of the mounted object.
