In these cases, the mounting wall portion 16a can be easily inserted and removed between the first support portion 22 and the second support portion 24. Further, the transport trolley 12 can be satisfactorily moved with the mounting wall portion 16a inserted between the first support portion 22 and the second support portion 24.

However, each of the above distance La, width Lb, width Lc, width Ld, depth Le, and protrusion height Lf is not particularly limited to the above relationship, and is appropriately depending on the type of the article to be transported and the like. Can be set.

In the transport trolley 12 according to the above embodiment, as shown in FIG. 1, the wall portion 16 is arranged so as to surround the outer periphery of the floor surface portion 14. In this case, by accommodating the article inside surrounded by the wall portion 16, it is easy and stable even when the article is large or heavy, or when the number of articles is large. It becomes possible to transport goods. Further, since the handle 10 for the transport trolley may be attached to any portion of the wall portion 16 surrounding the outer periphery of the floor surface portion 14, there is a degree of freedom in the direction in which the transport trolley 12 is moved, the layout of the transport trolley 12, and the like. The number of trolleys 12 can be further improved, and the convenience of the transport trolley 12 can be further improved.

The transport trolley 12 is not limited to the four wall portions 16 arranged in a square cylinder shape as described above. The wall portion 16 may be provided so as to stand up from at least a part of the floor surface portion 14. For example, as in the transport trolley 34 shown in FIG. 5, three wall portions 16 extending along three sides of the floor surface portion 14 formed in a rectangular shape in a plan view may be provided. Even in such a transport trolley 34, any one of the three wall portions 16 can be used as the mounting wall portion 16a. That is, the handle 10 for the transport trolley can be detachably attached to the transport trolley 34 shown in FIG. 5, similarly to the transport trolley 12 shown in FIGS. 1 and 2.

In the transport trolley 34 shown in FIG. 5, for example, in a plan view, both ends of the three wall portions 16 in the circumferential direction are not continuous with the other wall portions 16 and are open. When the wall portion 16 having an end portion that is not continuous with the other wall portions 16 is used as the mounting wall portion 16a, the mounting wall portion is located between the first support portion 22 and the second support portion 24 in the left-right direction. By inserting the 16a, the handle 10 for the transport trolley may be attached to the transport trolley 34.

Like the carrier 36 shown in FIG. 6, one wall portion 16 extending along one side of the floor surface portion 14 formed in a rectangular shape in a plan view may be provided. For such a transport trolley 36, one wall portion 16 can be used as a mounting wall portion 16a. That is, the handle 10 for the transport trolley can be detachably attached to the transport trolley 36 shown in FIG. 6, similarly to the transport trolley 12 shown in FIGS. 1 and 2. Also in the transport trolley 36 shown in FIG. 6, the handle 10 for the transport trolley is attached to the transport trolley 36 by inserting the mounting wall portion 16a in the left-right direction between the first support portion 22 and the second support portion 24. It is possible to wear it.

As in the transport trolley 38 shown in FIGS. 7 and 8, the upper loading portion 40 may be laminated above the wall portion 16. The upper loading portion 40 has, for example, a housing shape in which the upper surface opens, and has a side wall 42 and a bottom wall 44. The shape of the upper loading portion 40 is not particularly limited, and at least the bottom wall 44 may be provided.

A gap 48 is formed between the wall portion 16 and the bottom wall 44 of the upper loading portion 40 by interposing the leg portions 46. The legs 46 are provided at the four corners of the wall portions 16 arranged in a square cylinder shape in a plan view, and extend in the vertical direction. The upper loading portion 40 is fixed to the wall portion 16 via the leg portion 46. The upper loading portion 40 and the wall portion 16 may be detachably fixed. Articles can be loaded on the upper surface (inside surrounded by the side wall 42) of the bottom wall 44 of the upper loading portion 40.

When mounting the transport trolley handle 10 on such a transport trolley 38, for example, as shown in FIG. 7, first, the lower end side between the first support portion 22 and the second support portion 24 is attached to the mounting wall portion 16a. It faces the upper end side of the mounting wall portion 16a through the gap 48 between the upper loading portion 40 and the upper loading portion 40. In this state, for example, by moving the handle 10 for the transport trolley downward along the arrow X in FIG. 7, the mounting wall portion 16a is inserted between the first support portion 22 and the second support portion 24. As a result, as shown in FIG. 8, the handle 10 for the transport trolley can be mounted on the mounting wall portion 16a of the transport trolley 38.

On the other hand, when the handle 10 for the transport trolley is removed from the transport trolley 38, for example, the handle 10 for the transport trolley is moved upward along the arrow Y in FIG. 7 via the mounting wall portion 16a, the upper loading portion 40, and the gap 48. Move it. By pulling out the mounting wall portion 16a from between the first support portion 22 and the second support portion 24 in this way, the transport trolley handle 10 can be removed from the mounting wall portion 16a of the transport trolley 38.

Therefore, even for the transport trolley 38 provided with the upper loading portion 40, the upper loading portion 40 is laminated only by providing the leg portion 46 between the wall portion 16 and the upper loading portion 40 to form a gap 48. The handle 10 for the transport trolley can be easily attached and detached in substantially the same manner as when there is no such case.

In such a transport trolley 38, since articles can be loaded on the upper loading portion 40 as well, the loading capacity can be increased without increasing the size of the transport trolley 38 in the horizontal direction. As a result, the transportation efficiency using the transportation trolley 38 can be improved. Instead of this, it is possible to reduce the size of the transport trolley 38 without reducing the loading capacity of the transport trolley 38. The number of upper loading portions 40 stacked above the wall portion 16 is not limited to one, and a plurality of upper loading portions 40 may be laminated above 16.

As in the transport trolley 50 shown in FIG. 9, the floor surface portion 14 may be laminated above the lower loading portion 52 via the leg portions 46. In the transport trolley 50, the leg portion 46 may not be provided between the lower loading portion 52 and the floor surface portion 14. In the transport trolley 50, the wheels 18 are attached to the lower part of the lower loading part 52 instead of the lower part of the floor surface part 14. The lower loading portion 52 is, for example, in the shape of a housing having an open upper surface, and has a side wall 54 and a bottom wall 56. However, the shape of the lower loading portion 52 is not particularly limited, and the wall portion 16 and the floor surface portion 14 may be laminated above the lower loading portion 52. Articles can be loaded on the upper surface (inside surrounded by the side wall 54) of the bottom wall 56 of the lower loading portion 52. The handle 10 for the transport trolley can be detachably attached to the transport trolley 50 as in the case of the transport trolley 12 shown in FIGS. 1 and 2.

In the transport trolley 50 shown in FIG. 9, since it is possible to load articles on the lower loading portion 52 as well, the loading capacity can be increased without enlarging the transport trolley 50 in the horizontal direction, and eventually the transport trolley 50 can be transported. It is possible to improve the transportation efficiency using the trolley 50. Instead of this, it is possible to reduce the size of the transport trolley 50 without reducing the loading capacity of the transport trolley 50.

The present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof.

For example, in the above embodiment, in the left-right direction view, the first support portion 22 has a plate shape extending substantially parallel to the lower side of the spacer portion 30 of the second support portion 24. .. That is, the distance La between the first support portion 22 and the second support portion 24 is determined to be constant in the vertical direction.

However, for example, as in the case of the first support portion 58 shown in FIG. 10, the lower portion thereof may be inclined in a direction closer to the second support portion 24 than the upper portion. In such a handle 10 for a transport trolley, for example, the mounting wall portion 16a can be sandwiched in a portion where the first support portion 58 and the second support portion 24 are close to each other. This makes it possible to improve the stability of the handle 10 for the transport trolley mounted on the mounting wall portion 16a.

In this case, it is preferable to provide a curved portion 23 that curves in a direction away from the second support portion 24 at the lower end of the first support portion 58. As a result, even if the first support portion 58 is tilted as described above to form a portion in which the first support portion 58 and the second support portion 24 are close to each other, the first support portion 58 and the second support portion 58 are formed. The mounting wall portion 16a can be easily inserted between the 24 and the mounting wall portion 16a.

In the above embodiment, the first support portions 22 and 58 have a plate shape, but the present invention is not particularly limited to this. For example, the first support portions 22 and 58 may be in the shape of a plurality of rods, a plurality of cylinders, a plurality of pieces, or the like extending along the inner wall surface 17a of the mounting wall portion 16a.

In the above embodiment, the second support portion 24 has the plate-shaped portion 26, and the plate-shaped portion 26 is provided with the first support portions 22 and 58 via the spacer portion 30, but this is particularly the case. Not limited to. The first support portions 22 and 58 may be fixed to the strut portion 28 of the second support portion 24 via the spacer portion 30. In this case, the first support portions 22 and 58 do not have to have the plate-shaped portion 26.

In the above embodiment, the inclined extending portion 32 is provided above the portion of the support column 28 that supports the plate-shaped portion 26, and the grip portion 20 is provided on the upper end side of the inclined extending portion 32. And said. However, depending on the positional relationship between the handle 10 for the transport trolley and the user, the inclined extending portion 32 may be provided at the lower end of the second support portion 24. In this case, the inclined extending portion 32 is separated from the first support portions 22 and 58 as it goes downward. Further, a grip portion 20 is provided on the lower end side of the inclined extending portion 32.
