A movable vehicle comprising a box body configured with a bottom plate that can be fixed to the base plate, a support body that removably supports the box body, and a movable support part, that is, a vehicle part, equipped with a lifter and wheels that move the bottom plate up and down. Regarding bottom work vehicles.

ぼれの危険性が大きく極めて不都合であった。When handling large quantities of various parts, products, packages, and other items (transportation, storage, transportation, etc.), conventionally the items were stacked on pallets and the entire pallet was transported using a forklift, etc. This was extremely inconvenient for anything other than flat, large items, as there was a high risk of spillage.

合、作業者はいちいち前かがみになって物品の積み卸ろ
しをせねばならず、特に重量物品の場合作業者の肉体疲
労が激しく作業能率も極度に低下する。To prevent cargo from spilling, pallets with guards (boxes integrated on the pallet) have been proposed, but workers have to be careful when loading and unloading items into these pallets. Loading and unloading of goods requires bending over, which causes severe physical fatigue to the worker and extremely lowers work efficiency, especially in the case of heavy goods.

このような作業は工業用ロボットを用いて行なうことも

When goods are transported over long distances by truck or the like, it is unreasonable to store and transport the entire work vehicle, so it is necessary to transfer the goods to another pallet or box.

即ち、この作業車は保管、輸送機能を有さない。That is, this work vehicle does not have storage or transportation functions.

動底作業車は、箱体１０と車両部２０とから成り、箱体
１０は４本の支柱（コーナーポスト）２′のまわりに金
網等を張り巡らせてなる枠体２と、この枠体内に位置し
枠体の底部フランジ２“上に通常支持された可動底板１
とから成る。One embodiment of the present invention will be explained in detail with reference to the drawings. The movable bottom working vehicle of the present invention is composed of a box body 10 and a vehicle part 20, and the box body 10 is arranged around four pillars (corner posts) 2'. A frame body 2 made of a wire mesh or the like stretched over the frame body, and a movable bottom plate 1 located within the frame body and normally supported on a bottom flange 2″ of the frame body.
It consists of

枠体２の支柱２′の下端部及び枠体のクロスパー２′′
′にそれぞれ貫通孔１１．１２が設けである。The lower end of the support column 2' of the frame body 2 and the cross spar 2'' of the frame body
Through-holes 11 and 12 are provided in each of the holes 11 and 12, respectively.

車両部２０は枠体２の各支柱２′の下端部を支持する支
持体３を備え、各支持体３の上端部には、支柱の貫通孔
１１に整合する貫通孔１３が設けである。The vehicle section 20 includes a support 3 that supports the lower end of each support column 2' of the frame 2, and the upper end of each support 3 is provided with a through hole 13 that matches the through hole 11 of the support column.

車両部２０は更に、箱体１０の可動底板１を上下動させ
るためのりフタ−５をも備え、このリフターは、モータ
４にてリードネジ５′を回転させて腕５“を上下させリ
フト板５″′を上下動させる普通の型式のものでよい。The vehicle section 20 further includes a lifter 5 for vertically moving the movable bottom plate 1 of the box body 10. An ordinary type that moves the ``'' up and down will suffice.

車両部は車輪９を備えていて、手動で又は適当な駆動手
段で移動することができる。The vehicle part is equipped with wheels 9 and can be moved manually or by suitable drive means.

可動底板１は、フランジ２“上に位置しているときに、
枠体２の貫通孔１２に整合まる貫通孔１４を具備する。When the movable bottom plate 1 is located on the flange 2'',
A through hole 14 that is aligned with the through hole 12 of the frame body 2 is provided.

従って、第１図に示すように、箱体１０が車両部２０の
支持体３上に支持され可動底板が枠体２のフランジ２“
上に位置しているときには、貫通孔１１と１３、及び１
２と１４がそれぞれ整合する。Therefore, as shown in FIG.
When located at the top, through holes 11 and 13, and 1
2 and 14 respectively match.

そこで、係止ピン１５を、整合した貫通孔１１゜１３に
挿通すれば、枠体２が車両部２０の支持体３に固定され
ることになる。Therefore, by inserting the locking pins 15 into the aligned through holes 11 and 13, the frame body 2 is fixed to the support body 3 of the vehicle part 20.

反対に、係止ピン１５を、整合した貫通孔１２．１４に
挿通したときには、可動底板１が枠体２に固定される。Conversely, when the locking pins 15 are inserted into the aligned through holes 12.14, the movable bottom plate 1 is fixed to the frame 2.

それ故、係止ピン１５をこれらの整合した対をなす貫通
孔のいずれか一方へ挿通することにより、枠体と車両部
、又は底板と枠体を選択的に固定できる。Therefore, by inserting the locking pin 15 into either one of the matched pairs of through holes, the frame and the vehicle part or the bottom plate and the frame can be selectively fixed.

次に、本発明の作業車の作動を説明する。Next, the operation of the work vehicle of the present invention will be explained.

まず、物品６を作業車に積込むに当って、係止ピン１５
を貫通孔１１．１３の方へ挿通して枠体と車両部とを固
定すると共に、ペダル７の操作によりモータ４を駆動し
りフタい５を持上げて（固定されていなＧの可動底板１
を枠体２内で、第２図Ｂに示す作業高さ位置まで上昇さ
せる。First, when loading the article 6 onto the work vehicle, the locking pin 15
is inserted into the through hole 11.13 to fix the frame body and the vehicle part, and at the same time, by operating the pedal 7, the motor 4 is driven and the lid 5 is lifted (the movable bottom plate 1 of G, which is not fixed).
is raised within the frame 2 to the working height position shown in FIG. 2B.

次に、可動底板１上に物品を積重ねるに従って、リフタ
ー板５＃を順次下降させてゆく（第２図Ａ）。Next, as the articles are stacked on the movable bottom plate 1, the lifter plate 5# is successively lowered (FIG. 2A).

物品を枠体内に積込み終ったときには第１図の状態とな
る。When the articles have been loaded into the frame, the state shown in FIG. 1 is reached.

これとは反対に、作業車から物品を取出す場合は、第１
図の状態からりフタ−にて可動底板１を順次上昇させて
ゆけばよい。On the other hand, when removing items from a work vehicle, the
From the state shown in the figure, the movable bottom plate 1 can be raised one by one using the lid.

このようにして、本発明の作業車においては、作業者は
前かがみにならずに物品を積み卸ろしできる。In this way, in the work vehicle of the present invention, the worker can load and unload articles without bending forward.

次に、このようにして箱体１０内に積込んだ物品を保管
や長距離輸送の目的で倉庫やトラック等まで運搬するた
めに、車両部２０と箱体１０との固定関係を解除すると
共に可動底板１を枠体２に固定する。Next, in order to transport the articles loaded into the box 10 in this manner to a warehouse, truck, etc. for storage or long-distance transportation, the fixed relationship between the vehicle section 20 and the box 10 is released, and A movable bottom plate 1 is fixed to a frame 2.

この操作は、貫通孔１１．１３から係止ピン１５を抜取
って係止ピン１５を整合した貫通孔１２．１４へ挿通す
ることにより、容易に行なうことができる。This operation can be easily accomplished by removing the locking pin 15 from the through hole 11.13 and inserting the locking pin 15 into the aligned through hole 12.14.

次いで、リフター５を（第１図の状態から）更に下降さ
せて、枠体２に固定された底板１からリフト板５′′′
を引離す。Next, the lifter 5 is further lowered (from the state shown in FIG. 1) to remove the lift plate 5''' from the bottom plate 1 fixed to the frame 2.
pull away.

そして、フォークリフト等で底板１ごと箱体１０を持上
げて倉庫やトラックまで物品を運搬する（第３図）。Then, the box body 10 including the bottom plate 1 is lifted by a forklift or the like, and the goods are transported to a warehouse or a truck (FIG. 3).

この場合、物品は箱体１０内に収納されているので荷こ
ぼれを起こすことはなく、車両部２０を伴なわないので
、倉庫内にきちんと保管でき、長距離輸送にも適する。In this case, since the articles are stored in the box 10, spillage will not occur, and since the vehicle section 20 is not involved, the articles can be properly stored in the warehouse and are suitable for long-distance transportation.
