[0002]

2. Description of the Related Art A pallet formed by integral molding of a synthetic resin is known from Japanese Utility Model Publication No. 4-30096. The pallet disclosed in Japanese Utility Model Publication No. 4-30096 is formed by shifting the positions of decks extending in the same direction on deck boards on both sides so that they do not overlap vertically, and a plurality of deck boards on both sides. The fork insertion hole is formed between the tubular girders, and the fork insertion hole is formed between the tubular girders, and the whole is integrally formed of synthetic resin.

[0003] In the above-mentioned conventional example, the bar 3 formed on the deck board 1 on the front side is, as shown in FIG.
It has a U-shaped cross section that opens to the back side, and the crosspiece 4 formed on the deck board 2 on the back side has a U-shaped cross section that opens to the front side. Here, in the conventional example, the bars 3 and 4 extending in the same direction on the deck boards 1 and 2 on both sides.
The reason why they are shifted so that they do not overlap vertically is that the upper and lower dies 20, 21 are clamped as shown in FIG. In FIG. 6, arrows indicate the direction in which the upper and lower dies 20, 21 open.

[0004]

However, as described above, the crossbars 3, 4 extending in the same direction on the deck boards on both the front and back sides.
Are shifted so that they do not overlap vertically, water and debris flowing from the surface portion of the bar 3 formed on the deck board 1 on the front side accumulate inside the bar 4 formed on the deck board 2 on the back side. In addition, there is a problem that water on the upper surface of the bar 3 provided on the deck board 1 on the front side can be drained only from the end of the bar 3, so that water may remain on the front side.

Further, in the above-mentioned conventional example, when the object to be mounted is placed on the deck board 1 on the front side or when the object is lowered, it is slid on the deck board 1 on the front side.
There is a problem that the object to be mounted is caught on the corner of the crosspiece on the surface side and cannot be smoothly slid, so that the object to be mounted is hard to be loaded or unloaded. The present invention has been made in view of the problems of the above-described conventional example, and the water of the surface side rail is easily drained, and the water and dust flowing from the surface side rail flow into the inside of the rear side rail. Can be discharged smoothly, and when the object is placed on or unloaded from the deck board on the surface, it slides smoothly on the deck board on the surface without getting caught. The task is to be able to do

[0006]

In order to achieve the object of the present invention, the pallets of the present invention are arranged such that the crossbars 3, 4 extending in the same direction on the deck boards 1, 2 on both the front and back sides do not vertically overlap. The deck boards 1 and 2 on both sides are connected by a plurality of tubular girders 5 and a fork insertion hole 6 is formed between the tubular girders 5 and the whole is integrally formed of synthetic resin. In the pallet 7
The crosspiece 3 formed on the deck board 1 on the front side has a front piece 8 and both side pieces 9 protruding from both ends of the front piece 8 toward the back side.
The bar 4 formed on the deck board 2 on the back side is composed of a back piece 10 and both side pieces 11 protruding from both side ends of the back piece 10 toward the front side. In addition, a corner portion formed by the front piece 8 and the side pieces 9 is formed as an inclined piece 13, a discharge hole 14 is formed in the back piece 10, and a corner portion formed by the back piece 10 and the both side pieces 11 is formed by a slope piece 15. It is characterized by comprising. With such a configuration, even if water or dust adheres to the upper surface of the bar 3 formed on the deck board 1 on the front side, the water or dust travels along the inclined pieces 13 on both sides of the bar 3 on the front side. Since it falls down and falls down from the discharge hole 12 of the surface piece 8, it can be smoothly discharged from the upper surface of the bar 3 on the front side. Even if the water or dust discharged as described above falls into the inside of the bar 4 on the back side, the water or dust can be discharged from the discharge hole 14. In particular, the back piece 10 and the side piece Water and debris do not adhere to the corners formed by the inclined pieces 15 and the discharge holes 1
As a result, the liquid can be smoothly discharged from the discharge hole 14 by being guided to the fourth side. In order to place the object on the deck board 1 on the front side and to lower the object on the deck board 1 on the front side, when the object is slid on the deck board 1 on the front side, the inclined pieces 13 on both sides of the bar 3 on the front side are used. Due to the presence of the object, the object can be smoothly slid and slid without being caught, and the work of placing and lowering the object on the deck board 1 on the front side becomes easy. Further, the same effect is obtained even when the pallet 7 is used upside down.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The pallet 7 is integrally formed by injection molding of a synthetic resin, and has a plurality of cylindrical members for integrally connecting the deck board 1 on the front side, the deck board 2 on the back side, and the deck boards 1 and 2 on both the front and back sides. Digit 5
Constitutes the subject. The pallet 7 of the present invention is a double-sided pallet that can be used with either the front or back face up.

The tubular girders 5 include tubular girders 5a for connecting the left and right sides of the front and back deck boards 1 and 2 in the front-rear direction.
There is a tubular girder 5b connecting the central portions of the deck boards 1 and 2 on the front and back in the front-rear direction, and a fork insertion hole 6 is formed between the tubular girder 5a on both sides and the cylindrical girder 5b on the central portion. . Front, rear, left and right side walls are formed around the cylindrical girder 5, and the horizontal cross section has a rectangular shape.

On the deck board 1 on the front side, bars 3 are formed at intervals, and on the deck board 1 on the back side, bars 4 extending in the same direction as the bars 3 are positioned so as not to overlap vertically. Is shifted. Here, the crosspiece 3 formed on the deck board 1 on the front side includes a front piece 8 and both side pieces 9 protruding from both side ends of the front piece 8 toward the back side. And the discharge hole 12 is formed in the surface piece 8,
Further, an inclined piece 13 is formed at a corner portion formed by the surface piece 8 and the side pieces 9.

The crosspiece 4 formed on the deck board 2 on the back side comprises a back piece 10 and both side pieces 11 projecting from both side ends of the back piece 10 toward the front side. And
A discharge hole 14 is formed in the back piece 10, and further, an inclined piece 15 is formed in a corner portion formed by the back piece 10 and both side pieces 11. Here, as shown in FIG. 3, the side piece 9 of the bar 3 formed on the deck board 1 on the front side and the side piece 11 of the bar 4 formed on the deck board 2 on the back side are separated. In some cases, the side piece 9 and the side piece 11 are integrally continuous.

In the present invention, the deck boards 1 and 2 on both sides are shifted so that the bars 3 and 4 extending in the same direction do not overlap vertically, as in the conventional example. This is because the upper and lower dies 20, 21 can be formed by clamping the upper and lower dies 20, 21 as shown in FIG. The arrows in the figure indicate the direction in which the upper and lower dies 20, 21 open.

The pallet 7 having the above-described structure is used with one of the front and back faces up. Here, a case where the deck board 1 on the front side is placed above will be described. In order to place or unload the object on the pallet 7 on the front side, the object is slid on the pallet 7 on the front side. At the time of placing, the inclined piece 11 is present at the corner portion formed by the surface piece 8 and both side pieces 9, so that the mounted object does not get caught on the corner portion formed by the surface piece 8 and both side pieces 9, and smoothly slides. The object to be placed can be placed on the pallet 7 on the front side and lowered.

When the pallet 7 is washed or when the pallet 7 is put outdoors, it is rained, the water on the surface piece 8 is drained downward along the inclined piece 11 and the drain hole is formed. It will be drained downward from 12.
Then, even if water flows into the crosspiece 4 on the back side, the water can be drained to the outside from the discharge hole 14 provided in the back piece 10 of the crosspiece 4, so that water does not accumulate in the crosspiece 4. In this case, since the inclined piece 15 is provided at the corner formed by the side piece 11 and the back piece 10, water does not adhere to the corner formed by the side piece 11 and the back piece 10. Along the way, the water is smoothly drained to the discharge hole 14 side. Here, even if dust falls from the surface piece 8 into the bar 4, it can be discharged outside through the discharge hole 14. Also in this case, water does not adhere to the corner formed by the side piece 11 and the back piece 10 due to the presence of the inclined piece 15.

Although the above description has been made with reference to the case where the deck board 1 on the front side is turned up, the action of discharging water and dust is the same when the deck board 2 on the back side is turned upside down. It is.

[0015]

According to the present invention, as described above, the deck boards on the front and back sides are formed so that the crosspieces extending in the same direction are shifted from each other so as not to overlap vertically, and the plurality of deck boards on both front and back sides are provided. In a pallet which is connected by two cylindrical girders, has a fork insertion hole formed between the cylindrical girders, and is integrally formed of a synthetic resin as a whole, the crosspiece formed on the deck board on the front side is a surface piece and a surface piece. The crosspiece formed on the deck board on the back side is composed of the back piece and the side pieces protruding from both side ends of the back piece toward the front side. In addition, a discharge hole is formed in the front piece and a corner portion formed by the front piece and both side pieces is an inclined piece, and a discharge hole is formed in the back piece and the corner portion formed by the rear piece and both side pieces is a tilt piece. So on the surface side Even if water or dust adheres to the upper surface of the bar formed on the stick board, this water or dust will fall down along the inclined pieces on both sides of the surface bar and fall down from the discharge hole of the surface piece. It can be discharged smoothly from the upper surface of the bar on the front side, and even if water and dust fall into the inside of the bar on the back side, it can be discharged from the discharge hole and water and dust accumulate in the bar. In addition, due to the presence of the inclined piece, water and debris do not adhere to the corner portion formed by the back piece and the side piece, and the inclined piece guides the exhaust hole side to smoothly discharge from the discharge hole. In order to place the object on the deck board on the front side and to lower the object on the deck board, the inclined pieces on both sides of the crosspiece on the front side are used to slide the object on the deck board on the front side. The object is caught by the presence of Ku can slide slides smoothly, or placing the mounting object on the surface side of the deck board, in which work or down can be easily. And, in the present invention, the same effect as above can be obtained even if it is turned upside down.
