[Prior art]
Synthetic resin is easy to mold compared to wood, metal, etc., hygienic, does not corrode, and does not rust, but the synthetic resin itself is inferior to wood, metal, etc. When making a new product with synthetic resin, the strength is structurally supplemented.
That is, in the case of a synthetic resin pallet, the deck board portion is reinforced by providing reinforcing ribs vertically and horizontally on the inner surface of the surface plate-like body constituting the outer surface of the pallet, or a rod-like body having a U-shaped cross section that is strong against bending. The deck board part is configured with.
[0003]
[Problems to be solved by the invention]
However, in the case of such a structure in which reinforcing ribs are provided on the surface plate-like body or a synthetic resin pallet constituted by U-shaped ribs in the cross section, a structure in which the lower part and the side part are surrounded by walls and the upper part is open, That is, there is a drawback that a structure portion in which water and dust easily collect is formed.
[0004]
[Means for Solving the Problems]
As a result of various investigations to eliminate the drawbacks of the synthetic resin pallet as described above, the inventors have made specific structures for the upper and lower deck boards, so that water is splashed or dust is collected. It has been found that a pallet made of synthetic resin can be easily washed and dried even if it adheres.
[0005]
The gist of the present invention is a four-way synthetic resin made up of a top and bottom deck board and a plurality of hollow columnar members connecting the deckboards, and a space surrounded by the top and bottom deckboards and the hollow columnar member is a fork insertion port. In the insertion pallet, the upper deck board is structured to have a plate-like body on the outer surface side, and reinforcing ribs that are vertically and horizontally crossed on the inner surface of the plate-like body, and the lower deck board portion between adjacent hollow columnar members The inner surface side is a plate-like body and the outer surface of the plate-like body is provided with reinforcing ribs that intersect vertically and horizontally, or a structure that is a plurality of rod-like bodies that intersect each other vertically and horizontally, and a hollow columnar member The bottom deck board corresponding to is provided with an opening penetrating the inside and outside of the hollow columnar member between the rod-shaped members and between the side wall and the rod- shaped member of the hollow columnar member, and the side surface of the rod-shaped body facing this opening The It consists in the synthetic resin four-way insertion pallet, characterized in that the inclined surface.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of the synthetic resin four-way pallet of the present invention will be described with reference to the drawings.
1 is a perspective view showing the upper surface side of an example of the pallet of the present invention, FIG. 2 is a perspective view showing the back side of the pallet shown in FIG. 1, FIG. 3 is a cross-sectional view taken along the line AA in FIG. Drawing similar to FIG. 3 which shows the other example of the pallet of invention, FIG. 5, FIG. 6 is a longitudinal cross-sectional view of an example of the hollow columnar member of the pallet of this invention.
In the figure, 1 is a pallet, 2 and 2 'are upper and lower deck boards, 3 and 3' are hollow columnar members, 4 is a fork insertion port, 5 is a plate-like body, 6 is a reinforcing rib, and 7 is a fork insertion hole. 8 is an opening, 9 is a bottom deck board portion between adjacent columnar members, 10 is a rod-shaped body, 11 is a plate-like body, 12 is a reinforcing rib, and 13 is a reinforcing rib. Each aperture is shown.
[0007]
The pallet 1 of the present invention comprises upper and lower deck boards 2 and 2 'and a plurality of hollow columnar members 3 and 3' connecting the upper and lower deck boards 2 and 2 '. A space surrounded by the hollow columnar members 3, 3 ′ is a four-sided insertion with a fork insertion port 4, that is, a pallet that can be operated by inserting a fork such as a forklift from the four directions, Each of 2 'and hollow columnar members 3, 3' ... has a specific structure.
[0008]
As shown in FIGS. 1 and 3, the upper deck board 2 is configured by a plate-like body 5 on the outer surface side, that is, the side on which the load is loaded, and the inner surface, ie, the plate-like body 5 facing the fork insertion port. The surface has a structure in which reinforcing ribs 6 that intersect in the vertical and horizontal directions are provided.
As shown in FIG. 1, an appropriate number of apertures 13 may be provided in the plate-like body 5, and rubber or ethylene-containing material may be provided on the load-carrying surface of the plate-like body 5 or the fork contact portion of the reinforcing rib 6. An anti-slip material formed of a vinyl acetate copolymer or the like can be provided by appropriate means such as fitting, welding, and adhesion.
[0009]
As shown in FIGS. 2 and 3, the lower deck board 2 ′ has a structure in which a portion 7 corresponding to a portion where the fork insertion holes intersect is opened.
As shown in FIG. 4, the portion 9 between the adjacent hollow columnar members 3, 3 '... Of the lower deck board 2' has a plate on the inner surface side, that is, the side facing the fork insertion port 4. It is set as the structure 11, It is set as the structure which provided the reinforcing rib 12 which crossed the vertical and horizontal on the outer surface, ie, the outer surface side of the pallet 1, or the several rod-shaped body 10 which cross | intersects mutually vertically and horizontally as shown in FIG. Consists of.
[0010]
The hollow columnar members 3, 3 ′ have a hollow block shape, connect the upper and lower deck boards 2, 2 ′, and the fork insertion port 4 is provided between the hollow columnar members 3, 3 ′. It is formed. In consideration of the fact that a fork such as a forklift may come into contact with the hollow columnar members 3, 3 ′, etc., a reinforcing rib with a low height and a partition wall shape that reaches the top and bottom of the deck boards 2, 2 ′ A reinforcing plate 14 or the like is provided as appropriate.
[0011]
The hollow columnar members 3 and 3 'are usually integrated by welding the upper and lower pallet forming members, so that a sealed hollow structure is formed. However, in the present invention, a hollow columnar shape is not used. An opening 8 penetrating the inside and outside is provided in the lower deck board 2 'corresponding to the members 3, 3'.
By adopting such a structure, the inside of the hollow columnar members 3, 3 'can be washed with water or the like, which is very preferable in terms of hygiene.
[0012]
Further, when the hollow columnar members 3, 3 'are formed in a sealed state, when a small crack occurs in the hollow columnar members 3, 3' ... due to contact of a fork or the like, water penetrates from the cracks and becomes hollow. In some cases, the hollow columnar members 3, 3 ′, etc. of the present invention have an opening 8 in the lower part, so that such a problem does not occur.
[0013]
As the opening 8, as shown in FIG. 5, it is possible to simply provide a hole in the bottom deck board. However, with this structure, an undercut portion where dust easily adheres is formed, so as shown in FIG. It is preferable that the side wall of the opening 8 and the side surface of the rod-like body 10 be inclined or vertical so that moisture and dust do not easily stay.
The openings 8 are preferably provided in all the portions of the hollow columnar members 3, 3 ′ that are surrounded by ribs or partition walls so that water or the like is accumulated. If only a part of the rib is provided, a part of the rib or partition wall is notched and the surrounding part not provided with the adjacent opening 8 is connected to the surrounding part provided with the opening 8 so that water or the like is transmitted. It is good also as a structure.
[0014]
By doing in this way, it becomes a structure with which drainage is very hard to collect. For example, the bottom deck board has a plate-like body on the outer surface and a reinforcing rib on the inner surface side in the same way as the above-mentioned top deck board. However, it is conceivable to provide all the holes for draining water in the portion surrounded by the reinforcing ribs where water easily collects. However, dust and dust cannot be completely removed, which leaves a problem in terms of hygiene and is undesirable.
[0015]
In addition, it is conceivable that both the upper and lower deck boards are composed of rod-like bodies like the lower deck board described above, which is desirable for preventing drainage and accumulation of dust, but the upper deck board has a small surface area. Therefore, it is not desirable in terms of securing the contact area with the load, strength, and the like.
In addition, even if it is the lower surface deck board 9 between adjacent columnar members 3, 3, ..., the lower surface deck board part located in the side edge part of the pallet 1 is from the plate-shaped body 11 and the reinforcement rib 12 from strength. This structure is preferable, and the lower deck board portion 9 between the portion not located at the side edge of the pallet 1, that is, the columnar member at the center of the pallet and the columnar member at the middle of the side of the pallet is easy to clean. It is preferable to have a structure in which rod-shaped bodies intersect.
[0016]
Further, the pallet according to the present invention is generally flat on the outer surface side of the top deck board 2 on which loads are loaded.
[0017]
【The invention's effect】
As described above, the pallet of the present invention has a very good drainage, is a pallet that does not easily adhere to dust, and can handle small packages, packages that are easily damaged or easily crushed, and is a practically very good pallet. It is.
