The third horizontal member 60 is a long object having a closed cross section, specifically, a shape in which a hat-shaped opening is closed. The third horizontal member 60 is disposed between the first horizontal member 51 and the second horizontal member 56 and the installation surface, and is grounded to the installation surface. As shown in FIG. 3, the third horizontal member 60 is disposed in the left-right direction, which is the same direction as the front frame portion 21 a, the rear frame portion 21 b, and the second horizontal member 56. In the present embodiment, eight third horizontal members 60 are arranged in parallel, and are missing over a predetermined length at two places in the left-right direction.
FIG. 7 is a view showing a cross-sectional shape of the third horizontal member 60.
The third horizontal member 60 includes a rectangular portion 61 and a flange portion 62 that extends from the upper surface of the rectangular portion 61 to both sides.

Next, a method for assembling the cargo handling table 10 will be described. Here, it is assumed that the outer frame portion 20 and the horizontal portion 50 are already processed, and the corner members 31a to 31d and the ground members 38a to 38d are assembled.
First, the operator bridges and connects the first horizontal member 51 between the right frame portion 21c and the left frame portion 21d. Specifically, as shown in FIG. 4, the right side frame portion 21 c and the left side frame portion 21 d are coupled to the first horizontal member 51 using an attachment member 70. The attachment member 70 has a rectangular portion 71 and a flange portion 72. The flange portion 72 is coupled to the inner side of the right side frame portion 21c and the inner side of the left side frame portion 21d with rivets or the like, respectively.

Next, the operator causes the through holes 52 of the two first horizontal members 51 to communicate with each other, causes the second horizontal member 56 to penetrate the through holes 52 thus communicated, and the first horizontal member. Cross with 51. The operator performs this operation for all the 13 second horizontal members 56. At this time, since the number of the first horizontal members 51 is smaller than the number of the second horizontal members 56, the operation of penetrating the second horizontal member 56 through the first horizontal member 51 is easy. It is.
FIG. 8 is a perspective view showing a state in which the second horizontal member 56 is passed through the through hole 52 of the first horizontal member 51.

Next, the operator inserts the front ends of the second horizontal members 56 into the through holes 52 of the front frame portion 21a. Similarly, the rear ends of the second horizontal members 56 are respectively inserted into the through holes 52 of the rear frame portion 21b.
Next, the operator fits the pair of attachment portions 36 of the corner members 31a to 31d to the end portions of the front frame portion 21a, the rear frame portion 21b, the right frame portion 21c, and the left frame portion 21d, and attaches each attachment It connects with the rivet etc. through the hole 37. FIG.

Finally, the operator couples the third horizontal member 60 to the lower side of the second horizontal member 56. Specifically, in a state where the third horizontal member 60 is brought into contact with the second horizontal member 56 so as to be orthogonal to the flange portion 62 of the third horizontal member 60 and the second horizontal member 60. The lower surface portion 58 of the member 56 is coupled with a rivet or the like.
FIG. 9 is a view showing a state in which the flange portion 62 of the third horizontal member 60 is coupled to the lower surface portion 58 of the second horizontal member 56 with a rivet or the like.
In the cargo handling table 10 configured as described above, a load can be placed on the upper surfaces of the first horizontal member 51 and the second horizontal member 56. The load of the loaded luggage is received by the corner portion 30 from the first horizontal member 51 and the second horizontal member 56 via the outer frame portion 20 or directly by the third horizontal member 60. It is supported by that.

  Further, in the horizontal portion 50 of the cargo handling platform 10, a first horizontal member 51, a second horizontal member 56, and a third horizontal member 60 are disposed with a gap therebetween. Therefore, for example, even when the linen article is placed on the horizontal part 50 and pressed down from above to compress the linen article, air can escape to the lower side through the gap of the horizontal part 50. Linen articles can be easily compressed. In addition, since the gap between the adjacent second horizontal members 56 is set to 50 mm or more and 80 mm or less, specifically about 75 mm, the operator's feet working on the horizontal portion 50 are immersed in the gap. Can be prevented.

Further, as shown in FIG. 3, when viewed from the bottom, the eight third horizontal members 60 have a predetermined interval between the second and third from the front side, and between the sixth and seventh. There is a gap S1. Further, the eight third horizontal members 60 are missing so as to form a predetermined gap S2 over a predetermined length at two locations in the left-right direction. Therefore, when handling the cargo handling platform 10, a pair of claws of a forklift (not shown) can be inserted into the clearance S1 or the clearance S2 from any of the four side surfaces of the cargo handling platform 10.
In addition, when handling the cargo handling platform 10, a lifting member such as a rope may be wound around the insertion holes 33 of the corner members 31a to 31d, and the cargo handling may be performed by lifting with a forklift.

Moreover, the above-described cargo handling base 10 can be stacked in a plurality of stages.
FIG. 10 is a perspective view showing a state in which the cargo handling table 10 is stacked up and down via a support member. As shown in FIG. 10, in the first (lower) loading / unloading base 10, square pipes 80 as support members are inserted into the insertion holes 33 of the corner members 31 a to 31 d. The lower end of the rectangular pipe 80 is supported by abutting on the fixing bolt 40 in each insertion hole 33. On the other hand, the upper end of the square pipe 80 is in contact with the recesses on the lower surfaces of the grounding members 38a to 38d of the corner 30 of the second (upper) cargo handling platform 10.
In this way, by stacking the loading table 10 via the rectangular pipe 80, the loading table 10 in a state where the package is placed can be stacked, and a large number of packages can be loaded or stored. Note that the cargo handling table 10 on which the luggage is placed is not limited to being stacked in two stages, and may be stacked in three or more stages.

FIG. 11 is a perspective view showing a state in which the cargo handling table 10 on which no load is placed is stacked up and down. As shown in FIG. 11, the upper ends of the first-stage (lower) corner members 31a to 31d are brought into contact with the recesses on the lower surfaces of the ground members 38a to 38d of the corner portion 30 of the second-stage (upper) cargo handling base 10, respectively. It is touched.
In this way, by stacking the cargo handling bases 10 on which no cargo is placed, the cargo handling bases 10 on which no cargo is placed can be stacked, and space is saved when transporting or storing the cargo handling base 10 itself. Can be achieved. Note that the cargo handling table 10 on which the luggage is placed is not limited to being stacked in two stages, and may be stacked in three or more stages.

Further, when a load of a load is applied to one of the first horizontal member 51 and the second horizontal member 56 by passing the second horizontal member 56 through the first horizontal member 51. In addition, the load can be distributed to the other of the first horizontal member 51 and the second horizontal member 56, and the strength of the cargo handling table 10 can be prevented from being lowered.

  In the cargo handling platform 10 of this embodiment, the first horizontal member 51 has a hollow closed cross-sectional shape, and the second horizontal member 56 has an open cross-sectional shape. Therefore, since the through hole 52 that penetrates the first horizontal member 51 has an open cross-sectional shape corresponding to the second horizontal member 56, the first horizontal member 51 has a first horizontal width compared to the case where a closed cross-sectional shape is formed. It is possible to prevent the strength of the frame member 51 from being lowered.

  Moreover, the 1st horizontal member 51 of the cargo handling platform 10 of this embodiment is comprised combining the 1st side horizontal member 53 and the other side horizontal member 54 whose cross-sectional shape is respectively the same. Therefore, the one-side horizontal member 53 and the other-side horizontal member 54 can be formed by the same extrusion mold. Moreover, when forming the through-hole 52 in the 1st horizontal member 51, even if the 1st horizontal member 51 is a long thing, the through-hole 52 can be punched out with a press die. Therefore, the 1st horizontal member 51 can be manufactured cheaply and efficiently.
