That is, the cover portion 190 is attached to the support portion 144 by sandwiching the support portion 144 between the pair of cover sub-parts 190B. Then, the cover sub-section 190B and the auxiliary portion 145 are fastened by the rivet 191 or the like, so that the cover portion 190 is fixed to the support portion 144. The cover portion 190 is formed of, for example, a resin such as a silicone resin.
It is not necessary to fasten with the rivet 191. The cover portion 190 has a certain elastic force, and the cover portion 190 can be fixed to the support portion 144 by the force of the cover sub-part 190B sandwiching the support portion 144 without fastening or the like.
In the present embodiment, the cover portion 190 extends from the upper end to the lower end of the support portion 144 and covers the entire side of the support portion 144 opposite to the pillar portion 141. However, the cover portion 190 may be made shorter than the length from the upper end to the lower end of the support portion 144 so as to cover a part of the support portion 144 on the opposite side to the pillar portion 141. At this time, a plurality of cover portions 190 may be arranged so as to be arranged in the vertical direction with respect to one support portion 144.

手押し棒140は、柱部141の一端が有底孔128に挿入されることで、台車本体110に取付けられて、台車本体110に接続する。手押し棒140が台車本体110に取り付けられたとき、手押し棒140の軸線は台車本体110の載置部120の上面に略垂直であり、手押し棒140は載置部120の上面から上方に伸びるように配置される。
また、手押し棒140は、柱部141が有底孔128から抜き出されることで、台車本体110から取り外しできる。すなわち、手押し棒140は、台車本体110から取り外し可能である。
The push rod 140 is attached to the bogie main body 110 by inserting one end of the pillar portion 141 into the bottomed hole 128, and is connected to the bogie main body 110.

Placed in.
Further, the push rod 140 can be removed from the carriage main body 110 by pulling out the pillar portion 141 from the bottomed hole 128. That is, the push rod 140 is removable from the carriage body 110.

手押し棒140は、第1手押し棒140A、第2手押し棒140B、第3手押し棒140C、及び、第4手押し棒140Dの4個があり、それぞれ、角部R11〜R14に取付けられる。
そして、第1〜第4手押し棒140A〜Dの支持部144は、運搬台車100の上方から見たとき、台車本体110の側部R21〜R24に沿うように伸びる。なお、側部R22、R24は、それぞれ、運搬台車100の角部R11とR12とをつなぐ領域、運搬台車100の角部R13と角部R14とをつなぐ領域である。
このため、第1手押し棒140Aの支持部144の1つ及び第2手押し棒140Bの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。同様に、第3手押し棒140Cの支持部144の1つ及び第4手押し棒140Dの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。
また、第1手押し棒140Aの支持部144の1つ及び第4手押し棒140Dの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。同様に、第2手押し棒140Bの支持部144の1つ及び第3手押し棒140Cの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。
また、載置部120の上方には手押し棒140が配置されるのみであるため、載置部120の上方は、前後方向及び左右方向が閉塞しておらず、開放されている。
There are four push rods 140, a first push rod 140A, a second push rod 140B, a third push rod 140C, and a fourth push rod 140D, and they are attached to the corners R11 to R14, respectively.
Then, the support portions 144 of the first to fourth push rods 140A to D extend along the side portions R21 to R24 of the carriage main body 110 when viewed from above the transport carriage 100. The side portions R22 and R24 are regions connecting the corners R11 and R12 of the transport trolley 100 and regions connecting the corners R13 and the corners R14 of the transport trolley 100, respectively.
Therefore, one of the support portions 144 of the first push rod 140A and one of the support portions 144 of the second push rod 140B extend toward the other push rod 140, respectively. Similarly, one of the support portions 144 of the third push rod 140C and one of the support portions 144 of the fourth push rod 140D extend toward the other push rod 140, respectively.
Further, one of the support portions 144 of the first push rod 140A and one of the support portions 144 of the fourth push rod 140D extend toward the other push rod 140, respectively. Similarly, one of the support portions 144 of the second push rod 140B and one of the support portions 144 of the third push rod 140C extend toward the other push rod 140, respectively.
Further, since the push rod 140 is only arranged above the mounting portion 120, the upper portion of the mounting portion 120 is open without being blocked in the front-rear direction and the left-right direction.

次に、図1及び図2を参照して、底壁170について説明する。底壁170は、載置部120の上面に載置される板状の部材であり、矩形状のうち角部を切り欠いた形状である。底壁170には、例えばプラスチックダンボールが用いられる。プラスチックダンボールは、プラスチック又は合成樹脂を素材とし、中空の領域を備える板状の部材であり、軽量であって剛性に優れる。なお、底壁170には、木材の合板や単板等を用いてもよい。 Next, the bottom wall 170 will be described with reference to FIGS. 1 and 2. The bottom wall 170 is a plate-shaped member mounted on the upper surface of the mounting portion 120, and has a rectangular shape with corners cut out. For the bottom wall 170, for example, plastic cardboard is used. Plastic corrugated cardboard is a plate-shaped member made of plastic or synthetic resin and having a hollow region, and is lightweight and has excellent rigidity. The bottom wall 170 may be made of wood plywood, veneer, or the like.

次に図7を参照して、運搬台車100の使用方法について説明する。図7(a)は使用状態の運搬台車100の側面図であり、図7(b)は使用状態の運搬台車の正面図である。
ここでは、運搬台車100の積載物として、建築資材となる板材20を例にして説明する。板材20の長さは、平面視での載置部120の前後寸法より長いものとする。板材20の幅は、手押し棒140を台車本体110に取付けたときの、載置部120の上面から手押し棒140の上端までの長さに略等しいものとする。
まず、板材20の幅方向が運搬台車100の上下方向になるように板材20を立てる。そして、複数枚の板材20が運搬台車100の左右方向に並ぶように、板材20を、第1手押し棒140A及び第4手押し棒140Dと、第2手押し棒140B及び第3手押し棒140Cと、の間に配置して、載置部120に載せる。
次に、固定具10で板材20を固定する。固定具10は、固定具本体11と、フック12とを備える。固定具本体11は、布や紐等の、曲げたり折ったりする変形ができる部材で形成され、例えば帯状の部材である。フック12は、固定具本体11の両端に設けられ例えば鉄で形成される。固定具10の一方のフック12を、一方の係合部180に係合させる。そして、固定具本体11が板材20の上部にかかるように、固定具10の他方のフック12を、他方の係合部180に係合させる。
こうして、板材20が運搬台車100に固定されて、運搬台車100を安定して移動させることができる。
なお、板材20の寸法は上記の寸法に限定されるものではなく、例えば、板材20の幅は、手押し棒140を台車本体110に取付けたときの、載置部120の上面から手押し棒140の上端までの長さより、長かったり短かったりしてもよい。
また、固定具10はフック12を備えなくてもよい。このとき、例えば、固定具本体11の端部を係合部180のU字状の第1本体部186に結び付けることで、固定具10を係合部180に係合させる。また、固定具10は、フック12の代わりに、係合部180に係合できる他の部材を備えてもよい。
Next, a method of using the transport trolley 100 will be described with reference to FIG. 7. FIG. 7A is a side view of the transport trolley 100 in the used state, and FIG. 7B is a front view of the transport trolley in the used state.
Here, as a load of the transport trolley 100, a plate material 20 as a building material will be described as an example. The length of the plate member 20 is longer than the front-rear dimension of the mounting portion 120 in a plan view. The width of the plate member 20 is substantially equal to the length from the upper surface of the mounting portion 120 to the upper end of the push rod 140 when the push rod 140 is attached to the carriage main body 110.
First, the plate material 20 is erected so that the width direction of the plate material 20 is the vertical direction of the transport trolley 100. Then, the plate members 20 are arranged with the first push rods 140A and the fourth push rods 140D, and the second push rods 140B and the third push rods 140C so that the plurality of plate materials 20 are arranged in the left-right direction of the transport carriage 100. It is arranged between them and placed on the mounting portion 120.
Next, the plate material 20 is fixed with the fixture 10. The fixture 10 includes a fixture body 11 and a hook 12. The fixture body 11 is formed of a member that can be deformed by bending or folding, such as a cloth or a string, and is, for example, a strip-shaped member. The hooks 12 are provided at both ends of the fixture body 11 and are formed of, for example, iron. One hook 12 of the fixture 10 is engaged with one engaging portion 180. Then, the other hook 12 of the fixture 10 is engaged with the other engaging portion 180 so that the fixture main body 11 rests on the upper portion of the plate member 20.
In this way, the plate material 20 is fixed to the transport trolley 100, and the transport trolley 100 can be stably moved.
The dimensions of the plate member 20 are not limited to the above dimensions. For example, the width of the plate member 20 is such that the push rod 140 is formed from the upper surface of the mounting portion 120 when the push rod 140 is attached to the carriage body 110. It may be longer or shorter than the length to the top.
Further, the fixture 10 does not have to include the hook 12. At this time, for example, the fixture 10 is engaged with the engaging portion 180 by connecting the end portion of the fixture main body 11 to the U-shaped first main body portion 186 of the engaging portion 180. Further, the fixture 10 may include another member that can engage with the engaging portion 180 instead of the hook 12.

このように、運搬台車100は、図7(a)に示すように、板材20を、運搬台車100の前端及び後端よりも運搬台車100の外方にはみ出すように、運搬台車100に載置できる。したがって、運搬台車100は、載置部120に収まらない物を運搬できる。
また、第1手押し棒140Aの支持部144の1つ及び第2手押し棒140Bの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。同様に、第3手押し棒140Cの支持部144の1つ及び第4手押し棒140Dの支持部144の1つは、それぞれ他方の手押し棒140に向かって伸びる。よって、第1手押し棒140Aの支持部144及び第4手押し棒140Dの支持部144、又は、第2手押し棒140Bの支持部144及び第3手押し棒140Cの支持部144は、積載物となる複数の板材20の側面に接触する。こうして、手押し棒140が積載物を支持する。したがって、積載物が運搬台車100の上で安定する。
また、手押し棒140の支持部144は柱部141の両端から離間した位置で柱部141に対して固定される。よって、柱部141の端部と積載物となる複数の板材20との間に隙間ができる。したがって、使用者は、柱部141の上側の端部を掴むことができ、スムーズに運搬台車100を移動させることができる。
In this way, as shown in FIG. 7A, the transport trolley 100 places the plate material 20 on the transport trolley 100 so that the plate material 20 protrudes outside the transport trolley 100 from the front end and the rear end of the transport trolley 100. can. Therefore, the transport trolley 100 can transport an object that does not fit in the mounting portion 120.
Further, one of the support portions 144 of the first push rod 140A and one of the support portions 144 of the second push rod 140B extend toward the other push rod 140, respectively. Similarly, one of the support portions 144 of the third push rod 140C and one of the support portions 144 of the fourth push rod 140D extend toward the other push rod 140, respectively. Therefore, the support portion 144 of the first push rod 140A and the support portion 144 of the fourth push rod 140D, or the support portion 144 of the second push rod 140B and the support portion 144 of the third push rod 140C are a plurality of loads. Contact the side surface of the plate material 20 of. In this way, the push rod 140 supports the load. Therefore, the load is stable on the transport trolley 100.
Further, the support portion 144 of the push rod 140 is fixed to the pillar portion 141 at a position separated from both ends of the pillar portion 141. Therefore, a gap is formed between the end portion of the pillar portion 141 and the plurality of plate members 20 to be the load. Therefore, the user can grasp the upper end portion of the pillar portion 141 and can smoothly move the transport trolley 100.

また、手押し棒140は、支持部144における柱部141とは反対側を覆うカバー部190を備える。よって、積載物に接触するのはカバー部190であり、支持部144が積載物に接触することがない。したがって、積載物に傷が付くおそれが低減する。
また、載置部120の上面に底壁170が載置される。よって、運搬台車100に物品を収容しても、物品は底壁170に接触するのみであり、物品が載置部120に直接接触することがない。したがって、載置部120の損傷を防止できる。
また、運搬台車100の分解及び組み立ては、手押し棒140の端部を台車本体110の有底孔128から抜き出したり、手押し棒140の端部を台車本体110の有底孔128に挿入したりすることで行える。よって、特別な工具等が不要であり、簡単な作業で行うことができる。特に、手押し棒140の柱取付部143の上下方向の長さは手押し棒140の柱部141の半分程度の長さである。したがって、手押し棒140の支持部144からの抜き出しや、支持部144への挿入をスムーズに行うことができる。また、手押し棒140は上下対称な形状であるため、台車本体110の有底孔128に挿入に挿入する手押し棒140の端部を誤ることがない。
また、運搬台車100を分解することで、運搬台車100を使用しないときの保管スペースを節約できる。
また、運搬台車100は係合部180を備える。したがって、運搬台車100に積載物を載せて、図7を参照して説明したように固定具10を使うことで、積載物を安定させられる。
Further, the push rod 140 includes a cover portion 190 that covers the side of the support portion 144 opposite to the pillar portion 141. Therefore, it is the cover portion 190 that comes into contact with the load, and the support portion 144 does not come into contact with the load. Therefore, the risk of scratching the load is reduced.
Further, the bottom wall 170 is mounted on the upper surface of the mounting portion 120. Therefore, even if the article is housed in the transport trolley 100, the article only comes into contact with the bottom wall 170, and the article does not come into direct contact with the mounting portion 120. Therefore, damage to the mounting portion 120 can be prevented.
Further, when disassembling and assembling the transport trolley 100, the end of the push rod 140 is pulled out from the bottom hole 128 of the trolley main body 110, or the end of the push rod 140 is inserted into the bottomed hole 128 of the trolley main body 110. You can do it. Therefore, no special tool or the like is required, and it can be performed with a simple operation. In particular, the vertical length of the pillar mounting portion 143 of the push rod 140 is about half the length of the pillar portion 141 of the hand push rod 140. Therefore, the push rod 140 can be smoothly pulled out from the support portion 144 and inserted into the support portion 144. Further, since the push rod 140 has a vertically symmetrical shape, the end portion of the push rod 140 to be inserted into the bottomed hole 128 of the trolley main body 110 is not mistaken.
Further, by disassembling the transport trolley 100, the storage space when the transport trolley 100 is not used can be saved.
Further, the transport trolley 100 includes an engaging portion 180. Therefore, the load can be stabilized by placing the load on the transport trolley 100 and using the fixture 10 as described with reference to FIG. 7.

なお、支持部144は、図4に示す溝148の部分が部材で充填される等して、溝148を備えない構成であってもよい。この場合でも上記の効果を奏する。
また、運搬台車100の積載物と対向しない支持部144には、カバー部190が取り付けられていなくてもよい。すなわち、上方から見たときに、側部R21及びR23に沿う方向に伸びる支持部144にはカバー部190は取り付けられておらず、溝148を露出させてもよい。このように、運搬台車100の積載物と対向しない支持部144の溝148を露出させても、この溝148が露出した支持部144は、図7で説明した積載物である板材20とは接触しないため、板材20を傷つけるおそれが低減する。
また、次のように板材20を運搬台車100に載せてもよい。すなわち、板材20の幅方向が運搬台車100の上下方向になるように板材20を立てる。そして、複数枚の板材20が運搬台車100の前後方向に並ぶように、板材20を、第1手押し棒140A及び第2手押し棒140Bと、第3手押し棒140C及び第4手押し棒140Dと、の間に配置して、載置部120に載せてもよい。
また、運搬台車100と手押し棒140とをリベット等で固定したり、運搬台車100と底壁170とをリベット等で固定したりしてもよい。
また、運搬台車100は底壁170を備えなくてもよい。
The support portion 144 may not include the groove 148 because the portion of the groove 148 shown in FIG. 4 is filled with a member. Even in this case, the above effect is obtained.
Further, the cover portion 190 may not be attached to the support portion 144 that does not face the load of the transport trolley 100. That is, when viewed from above, the cover portion 190 is not attached to the support portion 144 extending in the direction along the side portions R21 and R23, and the groove 148 may be exposed. In this way, even if the groove 148 of the support portion 144 that does not face the load of the transport trolley 100 is exposed, the support portion 144 with the groove 148 exposed is in contact with the plate material 20 which is the load described with reference to FIG. Therefore, the risk of damaging the plate material 20 is reduced.
Further, the plate material 20 may be placed on the transport trolley 100 as follows. That is, the plate material 20 is erected so that the width direction of the plate material 20 is the vertical direction of the transport trolley 100. Then, the plate members 20 are arranged with the first push rod 140A and the second push rod 140B, and the third push rod 140C and the fourth push rod 140D so that the plurality of plate members 20 are lined up in the front-rear direction of the transport carriage 100. It may be arranged between them and placed on the mounting portion 120.
Further, the transport carriage 100 and the push rod 140 may be fixed with rivets or the like, or the transport carriage 100 and the bottom wall 170 may be fixed with rivets or the like.

The side wall 150 is arranged along the side portions R21 and R23 when viewed from above, and closes the left and right sides of the transport carriage 200. The left and right side walls 150 are referred to as side walls 150A and 150B, respectively.
The side wall 150 is a plate-shaped member, and for example, plastic cardboard is used for the side wall 150. A wood plywood, veneer, or the like may be used for the side wall 150.

また、上方から見たときに、側部R21及びR23に沿う方向に伸びる支持部144にはカバー部190は取り付けられておらず、溝148が露出する。そして、側壁150の両端が、対向する支持部144の溝148に挿入されることで、側壁150が台車本体110及び手押し棒140に取付けられる。
すなわち、側壁150Aの前方の端部が、第1手押し棒140Aの側部R21に沿う支持部144の溝148に挿入される。側壁150Aの後方の端部が、第4手押し棒140Dの側部R21に沿う支持部144の溝148に挿入される。また、側壁150Bの前方の端部が、第2手押し棒140Bの側部R23に沿う支持部144の溝148に挿入される。側壁150Bの後方の端部が、第3手押し棒140Cの側部R23に沿う支持部144の溝148に挿入される。こうして、側壁150A、Bが台車本体110及び手押し棒140に取付けられる。
側壁150は、台車本体110及び手押し棒140から取り外し可能である。すなわち、側壁150の端部が一対の支持部144の溝148に挿入されることで、側壁150が台車本体110及び手押し棒140に取り付けできる。また、側壁150の端部が一対の支持部144の溝148から抜き出されることで、側壁150が台車本体110及び手押し棒140から取り外しできる。
Further, when viewed from above, the cover portion 190 is not attached to the support portion 144 extending in the direction along the side portions R21 and R23, and the groove 148 is exposed. Then, both ends of the side wall 150 are inserted into the grooves 148 of the supporting portions 144 facing each other, so that the side wall 150 is attached to the trolley main body 110 and the push rod 140.
That is, the front end of the side wall 150A is inserted into the groove 148 of the support portion 144 along the side portion R21 of the first push rod 140A. The rear end of the side wall 150A is inserted into the groove 148 of the support portion 144 along the side portion R21 of the fourth push rod 140D. Further, the front end portion of the side wall 150B is inserted into the groove 148 of the support portion 144 along the side portion R23 of the second push rod 140B. The rear end of the side wall 150B is inserted into the groove 148 of the support portion 144 along the side portion R23 of the third push rod 140C. In this way, the side walls 150A and B are attached to the carriage body 110 and the push rod 140.
The side wall 150 is removable from the bogie body 110 and the push rod 140. That is, by inserting the end portion of the side wall 150 into the groove 148 of the pair of support portions 144, the side wall 150 can be attached to the trolley main body 110 and the push rod 140. Further, the side wall 150 can be removed from the dolly body 110 and the push rod 140 by pulling out the end portion of the side wall 150 from the groove 148 of the pair of support portions 144.

次に、図8及び図9を参照して、係止部160について説明する。図9は、側壁150の一部分の分解斜視図である。
係止部160は、取付部161と当接部162とを備える。取付部161は、側壁150に取り付けられる部材であり、図9に示す通り、底面部161Aと底面の両端から上方に伸びる一対の側面部161Bとを備える。底面部161Aと一対の側面部161Bとで囲まれる領域に側壁150が挿入されリベット163で固定されることで、取付部161は、側壁150に取り付けられる。
Next, the locking portion 160 will be described with reference to FIGS. 8 and 9. FIG. 9 is an exploded perspective view of a part of the side wall 150.
The locking portion 160 includes a mounting portion 161 and a contact portion 162. The attachment portion 161 is a member attached to the side wall 150, and includes a bottom surface portion 161A and a pair of side surface portions 161B extending upward from both ends of the bottom surface as shown in FIG. The mounting portion 161 is attached to the side wall 150 by inserting the side wall 150 into the region surrounded by the bottom surface portion 161A and the pair of side surface portions 161B and fixing the side wall 150 with the rivet 163.

当接部162は、取付部161の底面から、上方から見たときに載置部120の内側に伸びる底面延長部162Aと、底面延長部162Aの端部から下方に伸びる下方延長部162Bとを備える。そして、図9に示す例では、下方延長部162Bが外枠部材122Bの内側の側面(載置部120の内側を向く面)に接するように配置されることで、当接部162が外枠部材122Bに当接する。 The contact portion 162 includes a bottom surface extension portion 162A extending inward of the mounting portion 120 when viewed from above from the bottom surface of the mounting portion 161 and a downward extension portion 162B extending downward from the end portion of the bottom surface extension portion 162A. Be prepared. Then, in the example shown in FIG. 9, the lower extension portion 162B is arranged so as to be in contact with the inner side surface of the outer frame member 122B (the surface facing the inside of the mounting portion 120), so that the contact portion 162 is arranged in the outer frame. It comes into contact with the member 122B.

係止部160は、図8に示す通り、側壁150の下端部に3つ取り付けられる。係止部160の下方延長部162Bは、載置部120の凹部127に入り込む。側壁150に取り付けられた係止部160の下方延長部162Bは、外枠部材122B、Dの内側の側面に接するように配置される。なお、係止部160の下方延長部162Bと、外枠部材122B、Dの内側の側面との間には隙間があってもよい。
また、係止部160は、例えば、アルミニウム合金による押出し成形により一体的に形成される。なお、係止部160は、鉄製の金物等であってもよい。
As shown in FIG. 8, three locking portions 160 are attached to the lower end portion of the side wall 150. The lower extension portion 162B of the locking portion 160 enters the recess 127 of the mounting portion 120. The lower extension portion 162B of the locking portion 160 attached to the side wall 150 is arranged so as to be in contact with the inner side surface of the outer frame members 122B and D. There may be a gap between the lower extension portion 162B of the locking portion 160 and the inner side surface of the outer frame members 122B and D.
Further, the locking portion 160 is integrally formed by, for example, extrusion molding with an aluminum alloy. The locking portion 160 may be made of iron or the like.

このように、運搬台車200は、左右が側壁150で閉塞される。したがって、運搬台車200の積載物が、運搬台車200の左右方向にある物等によって傷つけられるおそれが低減する。
また、係止部160があるため、運搬台車200の積載物等により内側から側壁150が押されても、係止部160の下方延長部162Bが外枠部材122B、Dの内側の側面に接触する。したがって、載置部120の上方から見たとき、側壁150の下端が載置部120の上面から飛び出ることが、係止部160によって防止される。
また、側壁150及び底壁170にはプラスチックダンボール等が用いられる。したがって、運搬台車200が軽量になり、取り扱いが容易になる。
また、側壁150の取り外しや取り付けが容易であるため、運搬台車200に収容された物品や外部から衝撃等で側壁150が損傷しても、簡単な作業で側壁150を交換できる。
また、運搬台車200は、第1実施形態の運搬台車100と同様の効果を奏する。
In this way, the left and right sides of the transport trolley 200 are closed by the side walls 150. Therefore, the possibility that the load on the transport trolley 200 will be damaged by objects in the left-right direction of the transport trolley 200 is reduced.
Further, since the locking portion 160 is provided, even if the side wall 150 is pushed from the inside by a load or the like of the transport trolley 200, the lower extension portion 162B of the locking portion 160 comes into contact with the inner side surfaces of the outer frame members 122B and D. do. Therefore, when viewed from above the mounting portion 120, the locking portion 160 prevents the lower end of the side wall 150 from protruding from the upper surface of the mounting portion 120.
Further, plastic cardboard or the like is used for the side wall 150 and the bottom wall 170. Therefore, the transport trolley 200 becomes lightweight and easy to handle.
Further, since the side wall 150 can be easily removed and attached, even if the side wall 150 is damaged by an article housed in the transport trolley 200 or an impact from the outside, the side wall 150 can be replaced with a simple operation.
Further, the transport trolley 200 has the same effect as the transport trolley 100 of the first embodiment.

なお、係止部160は、側壁150ではなく、載置部120に取付けられていてもよい。このとき、係止部160は、例えば、矩形状の底面部と、底面部の1つの辺から上方に伸びる側面部とを備え、断面がL字状のアングル部材とする。係止部160は、台車本体110の側部R21及びR23の上面に設けられ、係止部160の側面部が側壁150の外側の側面に対向するように配置される。
また、運搬台車200は係止部160を備えなくてもよい。
また、台車本体110と側壁150とをリベット等で固定したり、手押し棒340と側壁150とをリベット等で固定したりしてもよい。
また、側壁150は、上方から見たときに側部R22及びR24に沿うように配置してもよい。また、運搬台車200には、側壁150を1個又は3個取り付けてもよい。このとき、載置部120の上方は前方、後方、左方、及び、右方の少なくともいずれかが開放される。したがって、この場合でも、運搬台車200の載置部120に収まらない物を運搬できる。
The locking portion 160 may be attached to the mounting portion 120 instead of the side wall 150. At this time, the locking portion 160 includes, for example, a rectangular bottom surface portion and a side surface portion extending upward from one side of the bottom surface portion, and is an angle member having an L-shaped cross section. The locking portion 160 is provided on the upper surfaces of the side portions R21 and R23 of the carriage body 110, and is arranged so that the side surface portion of the locking portion 160 faces the outer side surface of the side wall 150.
Further, the transport trolley 200 does not have to include the locking portion 160.
Further, the carriage body 110 and the side wall 150 may be fixed with rivets or the like, or the push rod 340 and the side wall 150 may be fixed with rivets or the like.
Further, the side wall 150 may be arranged along the side portions R22 and R24 when viewed from above. Further, one or three side walls 150 may be attached to the transport carriage 200. At this time, at least one of the front, the rear, the left, and the right is opened above the mounting portion 120. Therefore, even in this case, it is possible to carry an object that does not fit in the mounting portion 120 of the transport trolley 200.

また、運搬台車200には、側壁150を4個取り付けてもよい。このとき、側壁150は、上方から見たときに側部R21〜R24に沿うように配置され、載置部120の上方は、前後方向及び左右方向に閉塞する。側壁150は、両端を、対向する支持部144の溝148に挿入することで、容易に台車本体110及び手押し棒140に取付けられる。したがって、積載物が運搬台車200の載置部120に収まるときは、運搬台車200には側壁150を4個取り付けることで、固定具10を使うことなく安定して積載物を搬送できる。
なお、側壁150は、支持部144の溝148に挿入されて手押し棒140に取付けられるため、側壁150が挿入される溝148を備える支持部144にはカバー部190は取付けない。
Further, four side walls 150 may be attached to the transport carriage 200. At this time, the side wall 150 is arranged along the side portions R21 to R24 when viewed from above, and the upper portion of the mounting portion 120 is closed in the front-rear direction and the left-right direction. The side wall 150 can be easily attached to the carriage body 110 and the push rod 140 by inserting both ends into the grooves 148 of the supporting portions 144 facing each other. Therefore, when the load fits in the mounting portion 120 of the transport trolley 200, the load can be stably transported without using the fixture 10 by attaching four side walls 150 to the transport trolley 200.
Since the side wall 150 is inserted into the groove 148 of the support portion 144 and attached to the push rod 140, the cover portion 190 is not attached to the support portion 144 provided with the groove 148 into which the side wall 150 is inserted.
