By the way, such a transport cart 10 is provided with the recesses 30, 31, 32, 33 on the upper surface of the deck plate 13, so that when the original article is placed and transported, the stability of the article is improved. There was a problem of getting worse.
Also, when stacking trolleys, the dents on the lower trolley are covered with the trolleys that are placed on top, making it difficult to position the dents on the stack and the legs. was there.
[0005]
In view of such a situation, the present invention provides a transport cart that has good stability when an article is placed on a deck board and can be easily stacked and stacked when not used. The purpose is that.
[0006]
[Means for Solving the Problems]
The transport cart according to the present invention for achieving the above object is
On the upper surface of the substantially flat deck plate, an upper partition body having a predetermined height is integrally provided along a pair of sides facing each other, and continuously from the upper partition body below the deck plate. Extend the lower bulkhead together,
When two transport carts are stacked vertically and stacked, the lower surface of the lower bulkhead is in contact with the ceiling surface of the upper bulkhead, and the upper transport cart is slid in a substantially horizontal direction in this state. A carriage with a caster in which two carriages are positioned at predetermined positions by moving along a lower carriage,
The upper partition body and the lower partition body are provided with a substantially rectangular cutout that defines a fixed position of each other,
When the two transport carts are vertically crossed and overlapped, the notch portion of the upper bulkhead body and the notch portion of the lower bulkhead body are aligned with each other so that the two carts cannot be moved. It is characterized by having been made.
[0007]
According to the transport cart having such a configuration, the upper partition bodies at both ends can be rails, and the cutout portions of the lower transport cart can be moved while sliding on the upper partition body. Moreover, since it is comprised so that a mutual recessed part may fit when an upper conveyance trolley reaches | attains a predetermined position, it can position to a predetermined position.
Here, the entrance-side opening of the substantially rectangular notch provided in each of the upper partition and the lower partition is formed with a tapered guide slope whose width gradually decreases toward the inside of the notch. It is preferable.
[0008]
With such a configuration, when the upper partition body and the lower partition body are made to coincide with each other and slide, the positioning by the recess can be easily performed.
Furthermore, it is preferable that the width of the bottom surface is formed wider than the width of the ceiling surface in the cutout portion formed in the upper partition wall.
With such a configuration, the contact area becomes large when positioned at a predetermined position, so that the stability is good.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a transport cart according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a transport cart according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a bottom view thereof.
[0010]
The transport cart 20 has a rectangular deck plate 21, and a caster 22 is provided below the deck plate 21.
The deck plate 21 is formed in a smooth flat shape, but may be formed in a lattice shape, or a large opening may be formed in the center. The deck plate 21 is formed in a rectangular shape from a pair of long side edges and a pair of short side edges, and upper partition walls 26 and 26 are provided upright on the pair of long side edges, respectively. .
[0011]
On the other hand, on the lower side of the deck plate 21, lower partition walls 27, 27 are formed to be continuous with the upper partition bodies 26, 26. Further, the lower partition body 27 extends to the short side. Has been. Accordingly, the lower partition wall 27 is provided on the lower surface side of the deck plate 21 so as to surround the four sides.
In the upper partition walls 26 and 26, substantially rectangular cutout portions 28 and 28 are formed at positions spaced apart from the center in the length direction by a predetermined distance, respectively. The length S between the notches 28 and 28 is substantially equal to the separation distance S ′ between the two upper partition bodies 26 and 26. That is, the four notches 28 formed in the pair of upper partition bodies 26, 26 facing each other are formed at positions that are substantially square.
[0012]
As shown in the enlarged view of FIG. 4, the notch 28 formed in the upper partition body 26 has a width of the entrance side opening A wider than the inside, and a tapered guide slope 35 is formed there. Yes. Further, the width Y of the bottom surface 39 of the notch 28 is formed wider than the width X of the ceiling surface 36 of the upper partition body 26.
On the other hand, as shown in FIGS. 1 and 3, notches 29 are respectively formed on the lower surfaces of the pair of lower partitions 27 extending from the upper partitions 26 in which the notches 28 are formed. ing. The width B of the notch 29 is formed so as to accommodate the ceiling surface 36 of the upper partition wall 26. That is, the width B of the notch 29 is formed slightly wider than the width C of the ceiling surface 36. The notch 29 is also formed with a tapered guide slope 34 so that the entrance-side opening is widened.
[0013]
The transport cart 20 according to one embodiment of the present invention is configured as described above, and the operation thereof will be described below.
Now, a description will be given of a case where the transport cart 20 is empty and these are crossed and stacked in multiple stages.
First, as shown in FIG. 5, with respect to the lower transport cart 10 ′, the upper transport cart 10 is crossed by 90 ° and arranged vertically, and the cutout portions 29 and 29 of the upper transport cart 10 are arranged at the lower positions. It matches with the ceiling surface 36 of the upper partition bodies 26, 26. From this state, when the upper carriage 10 is pushed lightly in the horizontal direction, the notch 29 reaches the first notches 28, 28, but moves over the tapered guide slope 35. It does not fall into the portion 28 and continues to move further along the ceiling surface 36. When the second notch 28 located at the front is reached, all of the four notches 28 and the four notches 29 match each other, so that these notches 28 and 29 catch each other. Thus, the upper cart 10 falls into the lower cart 10 '.
[0014]
In this way, the two carriages 10 and 10 ′ are overlapped with each other in a posture different by 90 °. Further, the same operation may be performed when the third carriage 10 is overlaid thereon. Thereby, as shown in FIG. 6, three trolley | bogies can be piled up on cloth.
In this way, empty transport carts can be stacked, and the storage space can be reduced.
[0015]
When the two carriages are overlapped, the notch 29 of the lower partition wall 27 is matched with the wide bottom surface 39 of the notch 28, so that the contact area is large and can be assembled in a stable posture. it can. Further, when the notches 28 and 29 are matched with each other, the depression is promoted by the tapered guide slopes 35 and 34, so that they can be assembled quickly.
[0016]
As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all. For example, in the above embodiment, the lower partition walls 27 and 27 are provided also on the short side of the deck plate 21, but the lower partition body 27 at this position is not always necessary. However, if all the four sides are covered with the lower partition wall 27 in this way, the caster mounting portion can be covered from the outside, which is effective as a blindfold.
[0017]
Further, the upper partition body 26 can be provided so as to surround the four sides.
[0018]
【The invention's effect】
As described above, according to the transport carriage according to the present invention, the notch portion of the lower partition body of the upper transport carriage can be slid along the upper partition body of the lower transport carriage. Further, when the upper carriage reaches the predetermined position, the notch portions are matched with each other, so that the upper carriage can be quickly fitted. As a result, the upper transport cart becomes immovable and can be stacked in a state where the height is lowered.
