特開２０００−２２５８８５公報 There is a technique for indexing and transporting a trolley by lifting the lower part of the boat mounting end. (For example, patent document 1). In general, means such as mounting a forklift on a vehicle body and loading a load on a loading platform are widely known.
Japanese Patent Laid-Open No. 2000-225885

しかし乍ら、箱形荷台を装設させると共に、荷物を載せるテーブル及びリフトシリンダをリフトフレームに設け、縦軸回りにリフトフレームを回動自在に支持させる場合、前記縦軸を設ける支柱を箱形荷台に支持させることにより、箱形荷台を補強する必要があると共に、箱形荷台がリフトフレーム荷重によって変形し易い不具合がある。 However, when a box-shaped cargo bed is installed, a table for placing a load and a lift cylinder are provided on the lift frame, and the lift frame is rotatably supported around the vertical axis, the column provided with the vertical axis is a box-type. It is necessary to reinforce the box type carrier by supporting it on the carrier, and there is a problem that the box carrier is easily deformed by the lift frame load.

然るに、本発明は、請求項１の如く、箱形荷台を装設させると共に、荷物を載せるテーブル及びリフトシリンダをリフトフレームに設け、縦軸回りにリフトフレームを回動自在に支持させるトラックの荷物積み降し装置において、前記箱形荷台後側の枠体に縦軸を立設させ、枠体後側の荷台後部ドアより内側にリフトフレームを収納可能とさせたものである。 However, according to the present invention, as described in claim 1, a truck-shaped luggage carrier is provided, a table for loading the luggage and a lift cylinder are provided on the lift frame, and the lift frame is rotatably supported around the vertical axis. In the loading / unloading device, a vertical axis is erected on the frame on the rear side of the box-type loading platform so that the lift frame can be stored inside the loading platform rear door on the rear side of the frame.

また、請求項２の如く、縦軸の上下両端を枠体の上下フレーム部に取外し自在に固定させ、リフトフレームの基端を縦軸に固定させたものである。 Further, as described in claim 2, the upper and lower ends of the vertical axis are detachably fixed to the upper and lower frame portions of the frame body, and the base end of the lift frame is fixed to the vertical axis.

請求項１に係る発明は、箱形荷台を装設させると共に、荷物を載せるテーブル及びリフトシリンダをリフトフレームに設け、縦軸回りにリフトフレームを回動自在に支持させるトラックの荷物積み降し装置において、前記箱形荷台後側の枠体に縦軸を立設させ、枠体後側の荷台後部ドアより内側にリフトフレームを収納可能とさせたもので、剛性を有する枠体に強度良好にリフトフレームを支持させて、箱形荷台がリフトフレーム荷重によって変形する不具合など解消させ、走行中などには荷台内側にリフトフレームをコンパクトに収納して作業性を向上させることができるものである。 The invention according to claim 1 is an apparatus for loading and unloading a truck, in which a box-shaped loading platform is installed, a table on which loads are loaded, and a lift cylinder are provided on the lift frame, and the lift frame is rotatably supported around the vertical axis. The vertical frame is erected on the frame on the rear side of the box-shaped loading platform, and the lift frame can be stored inside the loading platform rear door on the rear side of the frame. By supporting the lift frame, it is possible to eliminate problems such as deformation of the box-type cargo bed due to the load of the lift frame, and to improve workability by compactly storing the lift frame inside the bed during traveling or the like.

また、請求項２に係る発明は、縦軸の上下両端を枠体の上下フレーム部に取外し自在に固定させ、リフトフレームの基端を縦軸に固定させたもので、荷台に対するリフトフレームの強度良好な取付けが行えると共に、荷物積み降ろし装置の不必要時には簡単に取外して、装置を作業の障害とさせることない良好な作業も容易に可能とさせることができるものである。 In the invention according to claim 2, the upper and lower ends of the vertical axis are detachably fixed to the upper and lower frame portions of the frame body, and the base end of the lift frame is fixed to the vertical axis. In addition to being able to perform a good installation, it is possible to easily remove the load unloading device when it is not necessary, and to easily perform a good operation without causing the device to be an obstacle to the operation.

以下、本発明の実施例を図面に基づいて詳述する。図１はトラック荷台の側面図、図２は同背面図、図３は平面図、図４は荷台の上昇側面図、図５は同背面図、図６は荷台の収納説明図であり、トラック１の箱形荷台２後面を左右ドア３によって開閉自在に構成すると共に、トラック１の車体を形成するシャーシ４に根太部材５を介して荷台２の床６を固定させる。また、荷台２の後端に横巾及び高さが略同一形状の枠体７を固設させ、枠体７に縦軸８アーム９を介してリフトフレームを回動自在な支持させるもので、枠体７の床６面上に固設する軸受台１１の軸１２と枠体７天板の軸１３との間に縦軸８を取外し自在に固定させると共に、リフトアーム１０を外側作業位置に固定させる位置決め用ロックピン１４を軸受台１１と縦軸８の位置決め板１５間に設けて、図３に示す如くリフトアーム１０を荷台２収納位置より縦軸８を中心として略９０度外側に回動させるとき、ロックピン１４によって位置固定させるように構成している。 Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is a side view of a truck bed, FIG. 2 is a rear view thereof, FIG. 3 is a plan view, FIG. 4 is a side elevation view of the carrier bed, FIG. 5 is a rear view thereof, and FIG. The rear surface of one box-shaped cargo bed 2 is configured to be freely opened and closed by left and right doors 3, and the floor 6 of the cargo bed 2 is fixed to a chassis 4 that forms the vehicle body of the truck 1 via a joist member 5. Further, a frame body 7 having substantially the same width and height at the rear end of the loading platform 2 is fixed, and the lift frame is supported on the frame body 7 via the vertical axis 8 arm 9 so as to be rotatable. The vertical axis 8 is detachably fixed between the shaft 12 of the bearing stand 11 fixed on the floor 6 surface of the frame body 7 and the shaft 13 of the frame body 7 top plate, and the lift arm 10 is moved to the outer working position. A locking pin 14 for positioning to be fixed is provided between the bearing base 11 and the positioning plate 15 of the vertical axis 8, and the lift arm 10 is rotated approximately 90 degrees outward from the loading platform 2 storage position about the vertical axis 8 as shown in FIG. When it is moved, the position is fixed by the lock pin 14.

さらに、前記リフトフレーム１０の最上部に軸１６を介して油圧リフトシリンダ１７を吊下げ、シリンダ１７のピストン１８を下方側で昇降させると共に、リフトフレーム１０に２本の角パイプ形シリンダレール１９を設け、図７に示す如く該レール１９に９０度方向の２つのガイドローラ２０・２１を下方側から出入自在にピストンフレーム２２上側を内挿させ、前記ピストン１８先端をピストンフレーム２２下端のピストンフレーム２３に軸２４を介して連結させ、カゴ車や荷物を載せる４形板状テーブル２５をピストンフレーム２２下端に軸２６を介して折畳み自在に連結させる。 Further, a hydraulic lift cylinder 17 is suspended on the uppermost part of the lift frame 10 via a shaft 16, and the piston 18 of the cylinder 17 is lifted and lowered on the lower side, and two square pipe cylinder rails 19 are mounted on the lift frame 10. As shown in FIG. 7, two guide rollers 20 and 21 in the direction of 90 degrees are inserted into the rail 19 so that the upper side of the piston frame 22 can be inserted and removed from the lower side. The four-shaped plate-like table 25 on which a car or a load is placed is connected to the lower end of the piston frame 22 via a shaft 26 so as to be foldable.

そして、荷台２に対する荷物の積み降し時には、荷台２外側位置でリフトフレーム１０を固定させ、荷台２内部に収納自在なデッキ２７を、床６と同じ高さのテーブル２５上面に展開させ、床６乃至テーブル２５上にカゴ車や荷物を移動させる一方、シリングフレーム１９に設ける昇降スイッチ２８の操作によってテーブル２５を昇降させ、地上乃至テーブル２５上にカゴ車や荷物を移動させ、荷台２にカゴ車や荷物を積み降す作業を行う。 Then, when loading / unloading the cargo onto / from the loading platform 2, the lift frame 10 is fixed at the outer position of the loading platform 2, and the deck 27 that can be stored inside the loading platform 2 is developed on the upper surface of the table 25 having the same height as the floor 6. 6 to the table 25, while the car and luggage are moved, the table 25 is moved up and down by operating the lift switch 28 provided on the shilling frame 19 to move the car and luggage on the ground or the table 25, and the basket 2 is moved to the loading platform 2. Work to load and unload cars and luggage.

上記から明らかなように、箱形荷台２を装設させると共に、荷物を載せるテーブル２５及びリフトシリンダ１７をリフトフレーム１０に設け、縦軸回りにリフトフレーム１０を回動自在に支持させるトラックの荷物積み降し装置において、前記箱形荷台２後側の枠体７に縦軸８を立設させ、枠体７後側の荷台後部ドア３より内側にリフトフレーム１０を収納可能とさせたもので、剛性を有する枠体７に強度良好にリフトフレーム１０を支持させて、箱形荷台２がリフトフレーム１０荷重によって変形する不具合など解消させることができ、走行中などには荷台２内側にリフトフレーム１０をコンパクトに収納して作業性を向上させることができる。 As is apparent from the above, the luggage of the truck on which the box-shaped loading platform 2 is installed and the table 25 and the lift cylinder 17 on which the luggage is placed are provided on the lift frame 10 and the lift frame 10 is rotatably supported around the vertical axis. In the loading / unloading device, a vertical axis 8 is erected on the frame body 7 on the rear side of the box-type cargo bed 2 so that the lift frame 10 can be stored inside the rear door 3 on the rear side of the frame body 7. The lift frame 10 is supported by the rigid frame body 7 with good strength, and the problem that the box-type cargo bed 2 is deformed by the load of the lift frame 10 can be solved. 10 can be stored compactly and workability can be improved.

また、縦軸８の上下両端を枠体７の上下フレーム部である軸１２・１３に取外し自在に固定させ、リフトフレーム１０の基端を縦軸８に固定させたもので、荷台２に対するリフトフレーム１０の強度良好な取付けが行えると共に、荷物積み降ろし装置の不必要時には簡単に取外して、装置を作業の障害とさせることない良好な作業も容易に可能とさせることができる。 In addition, the upper and lower ends of the vertical axis 8 are detachably fixed to the shafts 12 and 13 which are the upper and lower frame portions of the frame body 7 and the base end of the lift frame 10 is fixed to the vertical axis 8. The frame 10 can be attached with good strength, and can be easily removed when the baggage unloading device is not required, so that good work can be easily performed without causing the device to be an obstacle to work.
