Inside the recesses 2 of the plurality of legs 4 (in the recesses 2 of the other legs 4 excluding the recess 2 of the central leg 4 in the embodiment shown in the accompanying drawings), the upper surface side is upward. A support base portion 8 is formed which is a first convex portion 6 that protrudes to the bottom and a lower surface side that is a first concave portion 7 that is open downward so that the first convex portion 6 can be fitted therein. Here, the support base portion 8 is provided at a position deviated from the center of the recess 2.

Further, a part of the side wall portion 10 of the recess 2 of the leg portion 4 is projected inward to form a rattling prevention portion 13. The rattling prevention portion 13 serves as a second convex portion 11 having an upper surface protruding upward and a lower surface having a second concave portion 1 having a shape into which the second convex portion 11 can be fitted.
2, the upper end portion of the rattling prevention portion 13 is located above the upper surface of the support base portion 8.

The position and height of the support base 8 provided in the recess 2 offset from the center of the recess 2 and the position of the rattling prevention portion 13 provided on a part of the side wall of the recess 2 are described below. It is set as shown. That is, when stacking empty pallets 5 in multiple stages, the protrusions 3 of the upper pallet 5 are fitted in the recesses 2 of the lower pallet 5 and the upper protrusions 6 are formed in the first protrusions 6 in the recesses 2 of the lower pallet 5. The first recess 7 of the pallet 5 is fitted and the second recess 12 of the upper pallet 5 is vertically opposed to the second convex part 11 of the lower pallet 5 (also in the case of being vertically opposed and fitted). Including)
The first stacked state and the lower pallet 5 in a state where the upper pallet 5 is rotated by 90 ° or 180 ° (90 ° in the embodiment shown in FIGS. 1 to 9) from the first stacked state.
The projection 3 of the upper pallet 5 is fitted in the recess 2 of the upper pallet 5 and the first recess 7 of the upper pallet 5 is not fitted in the first projection 6 in the recess 2 of the lower pallet 5. The lower surface of the projecting portion 3 of the upper pallet 5 is placed on the convex portion 6 so that a fork is inserted between the upper surface of the mounting portion 1 of the lower pallet 5 and the lower surface of the mounting portion 1 of the upper pallet 5. The second recess 11 of the upper pallet 5 does not face the second recess 11 of the lower pallet 5 in the vertical direction in which the gap 9 is formed, and the upper pallet 5 is not attached to the side surface of the second recess 11. The height of the support base 8, the position of the support base 8 in the recess 2 and the rattling prevention so that the second stacked state in which the side wall portions 10 of the recess 2 other than the rattling prevention portion 13 face each other is obtained. Part 13
The position within the recess 2 is set.

In the second stacked state, the vertical length of the fork insertion gap 9 formed between the mounting portions 1 of the upper and lower pallets 5 is set to about 30 to 50 mm so that the fork of the forklift can be inserted. I am doing it. Also,
The rattling prevention unit 13 includes a rattling prevention unit 13 provided on the side wall 10 in the front-rear direction of the leg 4 and a rattling prevention unit 13 provided on the left and right of the leg 4. ing.

When the pallet 5 having the above-described structure is manufactured, transported or stored, as shown in FIG. 9, the projection 3 of the upper pallet 5 is fitted into the recess 2 of the lower pallet 5 and the lower pallet 5 is inserted. It is said that the first recess 7 of the upper pallet 5 is fitted into the first projection 6 in the recess 2 of the pallet 5 and the second recess 12 of the upper pallet 5 is fitted into the second projection 11 of the lower pallet 5. The pallets 5 are stacked in the first stacked state, and by setting the first stacked state in this manner, the upper and lower pallets 5 are in close contact with each other, and the bulk in the stacked state can be reduced.

On the other hand, at the warehouse, collection / delivery and physical distribution stages,
Empty pallets are stacked in multiple stages to save space, but unlike the first stacked state described above so that the pallets 5 can be immediately taken out, the upper pallets 5 are compared to the first stacked state. 90 ° in plan view
The pallets are rotated and stacked as shown in FIG. 10. In this case, the protrusion 3 of the upper pallet 5 is fitted into the recess 2 of the lower pallet 5 and the first protrusion 6 in the recess 2 of the lower pallet 5 is inserted. The lower surface of the protrusion 3 of the upper pallet 5 is placed on the first convex portion 6 without fitting the first recess 7 of the upper pallet 5 to the upper surface of the mounting portion 1 of the lower pallet 5 and the upper step. A gap 9 for inserting the fork is formed between the pallet 5 and the lower surface of the mounting portion 1, and the second recess 12 of the upper pallet 5 is opposed to the second recess 11 of the lower pallet 5 in the vertical direction. The second stacked state is achieved in which the side wall portion 10 of the concave portion 2 other than the rattling prevention portion 13 of the upper pallet 5 is opposed to the side surface of the second convex portion 11 without being caused to do so.

With such a second stacking state, the upper pallet 5 can be lifted and taken out while the fork is inserted in the fork insertion gap 9 and supported by the fork, and a new empty pallet can be obtained. When the pallets 5 are stacked, the second pallet 5 can be stacked on the lower pallet 5 with the forks inserted between the legs 4 and supporting them.

By the way, in the second stacked state,
Since the side wall portion 10 of the concave portion 2 other than the rattling prevention portion 13 of the upper pallet 5 faces the side surface of the second protrusion 11 of the lower pallet 5, the leg portion of the lower pallet 5 is formed. The leg portion 4 of the pallet 5 on the upper stage in the inside of 4 can be prevented from being displaced laterally by the rattling prevention portion 13.

That is, the leg portion 4 has the side wall portion 10 inclined so that the leg portion 4 of the upper and lower pallets 5 can be fitted into the leg portion 4 so as to be wider toward the upper opening side. When the lower surface of the protrusion 3 of the upper pallet 5 is placed on the first protrusion 6 of the pallet 5, the legs 4 of the upper pallet 5 are lifted by the height of the first protrusion 6, If the rattling prevention portion 13 is not provided as in the comparative example shown in FIG. 22, the inner surface of the side wall portion 10 of the leg portion 4 of the lower pallet 5 and the side wall portion of the leg portion 4 of the upper pallet 5 are assumed. The gap M between the outer surface of 10 increases. For example, FIG.
2, A = 100 mm, B = 60 mm, C = 40
mm, the thickness of the side wall 10 is 3 mm, and the inclination angle α of the side wall 10 is 10 °, the gap M is 7 mm,
M + M = 14mm on both front and rear sides, M + M = 14 on both left and right sides
mm, a gap is generated. Therefore, when a large number of pallets 5 are stacked vertically, the pallets 5 may rattle in the lateral direction, which may cause the pallets 5 to fall. However, in the present invention, by providing the rattling prevention portion 13, in the second stacked state in which the lower surface of the protrusion 3 of the upper pallet 5 is placed on the first convex portion 6 of the lower pallet 5, The side wall portion 10 of the recess 2 other than the rattling prevention portion 13 of the upper pallet 5 is provided on the side surface of the second protrusion 11 of the rattling prevention portion 13 provided on the side wall portion 10 of the leg 4 of the lower pallet 5. By facing each other, the gap N between the side surface of the second convex portion 11 and the side wall portion 10 of the concave portion 2 other than the rattling prevention portion 13 of the upper pallet 5 can be reduced, and the rattling of the pallet 5 in the lateral direction can be reduced. It is possible to suppress the contact. By the way, in FIG. 10, A = 1
00 mm, B = 60 mm, C = 40 mm, the thickness of the side wall portion 10 is 3 mm, the inclination angle α of the side wall portion 10 is 10 °,
The protrusion length of the rattling prevention portion 13 to the inside of the concave portion 2 is set to 4 m.
When m is set, the above gap N becomes 3 mm, and N + N = 6 mm in the front-rear direction and N + N = 6 mm in both left and right sides. Even if they are stacked in multiple layers, there is no risk of falling.

As the rattling prevention portion 13, as shown in FIG. 2, the rattling prevention portion 13 provided on the side wall portion 10 in the front-rear direction of the leg portion 4 and the rattling prevention portion 13 in the left and right direction of the leg portion 4. Since the rattling prevention portion 13 is provided, even if the pallets 5 are vertically stacked in multiple stages in the second stacked state,
It is possible to suppress rattling in the front-rear direction and the left-right direction.

In the normal use of the pallet 5, the load is placed on the placing part 1 and the pallet 5 is used in the same manner as a normal pallet. By moving the forklift with it lifted up, you can move to the desired place. In addition,
In the figure, reference numeral 20 denotes a rib provided at the outer end edge portion of the upper surface of the placing portion 1 of the pallet 5 for suppressing the fall of luggage. Reference numeral 21 is a rubber member for preventing slipping of luggage.

Next, another embodiment of the present invention will be described with reference to FIGS. 11 to 17. In this embodiment, an example in which the quadrangular plate-shaped mounting portion 1 has a rectangular shape in plan view (that is, an example of the rectangular pallet 5) is shown, and the four corners of the rectangular mounting portion 1 and each Leg portions 4 each having a concave portion 2 on the upper surface side and a projecting portion 3 on the lower surface side are provided in the central portion of the side and the central portion of the mounting portion 1, respectively. In the present embodiment, the mounting portion 1 has a rectangular shape. Therefore, the plurality of leg portions 4 are provided at positions of 180 ° rotational symmetry with the center of the mounting portion 1 as the center point.

Also in this embodiment, in the concave portions 2 of the plurality of leg portions 4, the upper surface side is the first convex portion 6 protruding upward, and the lower surface side is the lower portion having a shape into which the first convex portion 6 can be fitted. A support base 8 is formed, which is a first recess 7 that is open at the bottom. The support base portion 8 is provided at a position deviated from the center of the recess 2. Also in this embodiment, a part of the side wall 10 of the recess 2 of the leg 4 is projected inward to form a rattling prevention part 13, and the rattling prevention part 13 is The upper surface side is a second convex portion 11 protruding upward, and the lower surface side is a second concave portion 12 having a shape that can be fitted into the second convex portion 11 and opening downward, and an upper end portion of the rattling prevention portion 13. Are located above the upper surface of the support base 8.

Here, the position and height of the support base 8 provided in the recess 2 offset from the center of the recess 2 and the position of the rattling prevention portion 13 provided on a part of the side wall of the recess 2 are as follows. It is set as shown. That is, when stacking empty pallets 5 in multiple stages, the protrusions 3 of the upper pallet 5 are fitted in the recesses 2 of the lower pallet 5 and the upper protrusions 6 are formed in the first protrusions 6 in the recesses 2 of the lower pallet 5. The first recess 7 of the pallet 5 is fitted and the second recess 12 of the upper pallet 5 is vertically opposed to the second convex part 11 of the lower pallet 5 (some of which are fitted so as to be opposed vertically) Including)
The first pallet 5 and the lower pallet 5 with the upper pallet 5 rotated 180 ° from the first stacked state
The projection 3 of the upper pallet 5 is fitted in the recess 2 of the upper pallet 5 and the first recess 7 of the upper pallet 5 is not fitted in the first projection 6 in the recess 2 of the lower pallet 5. The lower surface of the projecting portion 3 of the upper pallet 5 is placed on the convex portion 6 so that a fork is inserted between the upper surface of the mounting portion 1 of the lower pallet 5 and the lower surface of the mounting portion 1 of the upper pallet 5. The second recess 11 of the upper pallet 5 does not face the second recess 11 of the lower pallet 5 in the vertical direction in which the gap 9 is formed, and the upper pallet 5 is not attached to the side surface of the second recess 11. The height of the support base 8, the position of the support base 8 in the recess 2 and the rattling prevention so that the second stacked state in which the side wall portions 10 of the recess 2 other than the rattling prevention portion 13 face each other is obtained. Part 13
The position within the recess 2 is set.

In the second stacked state, the vertical length of the fork insertion gap 9 formed between the mounting portions 1 of the upper and lower pallets 5 is set to about 30 to 50 mm so that the fork of the forklift can be inserted. I am doing it. When the pallet 5 having the above-described structure is manufactured, transported or stored, as shown in FIG. 16, the projection 3 of the upper pallet 5 is fitted into the recess 2 of the lower pallet 5 and the pallet 5 of the lower pallet 5 is inserted. The pallets 5 are stacked in the first stacking state in which the first recesses 7 of the upper pallet 5 are fitted into the first projections 6 in the recesses 2. By setting the first stacking state in this way, the upper and lower tiers are stacked. The pallets 5 can be in close contact with each other to reduce the bulk in the stacked state.

On the other hand, at the warehouse, collection / delivery and physical distribution stages,
Empty pallets are stacked in multiple stages to save space, but unlike the above first stacked state so that the pallets 5 can be immediately taken out, the upper pallet 5 is different from the first stacked state in the first stacked state. 180 in plan view
17 is rotated and stacked as shown in FIG. 17. In this case, the upper pallet 5 is placed in the recess 2 of the lower pallet 5.

As described above, according to the first aspect of the present invention, as described above, the upper surface of the mounting portion having a rectangular plate shape is a recess having an upper opening, and the lower surface is a recess. A plurality of leg portions whose side wall portions are inclined so as to be wider toward the upper opening side which is a protruding portion of a shape that can be formed are formed, and the plurality of leg portions are rotated by 90 ° about the center of the mounting portion as a rotation center. Alternatively, in a pallet provided at a position of 180 ° rotational symmetry, a support base part is formed in the recess, where the upper surface side is a first convex portion that projects upward and the lower surface side is a first concave portion that opens downward. A first stacked state in which the protrusion of the upper pallet is fitted in the concave portion of the pallet and a first recess of the upper pallet is fitted in the first convex portion in the concave portion of the lower pallet, and a first stacked state To the upper pallet 90 ° While rotating by 180 °, the protrusion of the upper pallet fits into the recess of the lower pallet, and the first recess of the upper pallet does not fit into the first protrusion of the recess of the lower pallet. 1 The lower surface of the protrusion of the upper pallet is placed on the convex portion, and a fork insertion gap is formed between the upper surface of the lower pallet mounting portion and the lower surface of the upper pallet mounting portion. Since the height of the support base and the position of the support base in the recess are set so that the two stacked states can be obtained, when stacking the pallets in the first stacked state, the stacking volume is increased. It can be made low, and it is effective in saving space during production, transportation, and storage. On the other hand, when stacking empty pallets at the warehouse, collection and distribution stage, or in the logistics stage, stacking in the second stacking state A fork insertion gap can be formed between upper and lower pallets, and the upper pallet can be supported by a fork and taken out, or can be supported by a fork and stacked on the lower pallet. In addition, a part of the side wall of the recess is projected inward to form a rattling prevention part, and the rattling prevention part is positioned above the upper surface of the support base part in the second stacked state. The rattling prevention section of the upper pallet is attached to the side surface of the rattling prevention section of the lower pallet without the rattling prevention section of the upper pallet vertically facing each other. Since the side walls of the recesses other than the portions where the pallets are provided face each other, the rattling prevention portion suppresses the rattling of the legs of the upper pallet in the legs of the lower pallet in the lateral direction. As a result, even if the pallets are vertically stacked in the second stacking state, the pallets will not be laterally displaced and fall down.

In addition to the effect of the invention according to claim 1, in the invention according to claim 2, the rattling prevention portion provided on the side wall portion in the front-rear direction of the leg portion, and the leg portion. Since the rattling prevention portion provided in the left-right direction is provided, rattling in the front-rear direction and the left-right direction can be suppressed in the second stacked state.
