Description

The present invention relates to a pallet used for transporting various kinds of cargo by a forklift or the like.

Conventionally, as this type of pallet, for example, as described in Patent Document 1, an insertion hole is provided in the upper surface of a synthetic resin pallet, and a rubber non-slip material is inserted into the insertion hole. Has been done. The non-slip material prevents skidding of the mounted object placed on the upper surface of the pallet. In addition, the anti-slip material inserted into the insertion hole formed through the fork insertion portion of the pallet has an upper surface portion that prevents the mounted object from skidding, and the fork inserted into the fork insertion portion. The upper surface hits the lower surface of the non-slip material to prevent the pallet from skidding with respect to the fork. As the pallet, there are a single-sided type in which only one side is a deck surface on which luggage is placed, and a double-sided type in which both sides are deck surfaces.

Japanese Patent No. 3012507 (paragraph 0014, FIG. 1)

However, in the above-mentioned conventional pallet, the insertion hole of the pallet expands due to the hot water during cleaning, especially when cleaning with hot water, and hot water infiltrates between the insertion hole of the pallet and the non-slip material. May accumulate. This water remains without evaporating even after washing, and gradually exudes to the deck surface side, which is the upper surface side of the pallet, which may wet the object to be placed.

The present invention has been made in view of this point, and the problem is that water is prevented from accumulating between the insertion hole of the pallet and the anti-slip material during cleaning, and the object is wet during use after cleaning. The purpose is to provide a pallet that can prevent the above.

In order to solve the above-mentioned problems, in the present invention, in a pallet in which at least one surface of the pallet is a deck surface on which luggage is placed, an insertion hole for inserting a non-slip material is provided in the deck surface, and the insertion hole is provided. A groove portion is formed on the inner peripheral surface of the above so that water collected between the anti-slip material and the insertion hole can be discharged to the outside of the insertion hole when the anti-slip material is inserted.

In this configuration, even when water enters between the insertion hole on the deck surface and the non-slip material when cleaning the pallet, the water is discharged to the outside of the insertion hole through the groove formed on the inner peripheral surface of the insertion hole. Therefore, it does not collect between the anti-slip material and the insertion hole. As a result, it is possible to prevent the mounted object from getting wet by the water accumulated between the anti-slip material and the insertion hole during use after cleaning.

Here, it is preferable that the groove portion is continuously formed so as to straddle between the opening on the deck surface mounting side of the insertion hole and the opening on the deck surface fork insertion portion side. In this case, when water enters between the insertion hole on the deck surface and the non-slip material during cleaning of the pallet, the water reaches the opening on the deck surface mounting side of the insertion hole and the deck surface fork insertion portion side due to its own weight. Of the openings, the water will be discharged smoothly and quickly to the outside of the insertion hole through the groove facing the opening located on the lower side, ensuring that water collects between the non-slip material and the insertion hole. Can be prevented.

According to the pallet of the present invention, even when water enters between the insertion hole on the deck surface and the non-slip material during cleaning, the water is discharged to the outside of the insertion hole through the groove formed on the inner peripheral surface of the insertion hole. Therefore, since it does not collect between the non-slip material and the insertion hole, it is possible to prevent the mounted object from getting wet by the water collected between the non-slip material and the insertion hole during use after cleaning. ..

Hereinafter, embodiments, which are embodiments for carrying out the present invention, will be described with reference to the drawings.

FIG. 1 shows the overall configuration of the pallet 1 according to the embodiment of the present invention. The pallet 1 is mainly made of a synthetic resin such as PP or PE, and includes a deck surface 2 on which luggage is placed and a fork insertion portion 3.

The pallet 1 includes a four-sided pallet and a two-sided pallet, and the present invention may be of any type. Note that FIG. 1 shows an example of a two-way insertion in which two fork insertion portions 3 are provided in parallel.

Further, in the pallet 1, the integrally molded pallet, which is entirely molded by integrally molding synthetic resin, and the two pallet halves 1a and 1b are separately molded, and both pallet halves 1a and 1b are welded and integrated. Although it is roughly classified into a welding type pallet, the present invention may be of any type. Note that FIG. 1 illustrates a welding type pallet.

Further, as the pallet 1, there are a double-sided use type in which both sides have a deck surface 2 and a single-sided use type in which only one side has a deck surface 2. But it may be. In other words, in the present invention, at least one surface of the pallet 1 may be a deck surface 2 on which luggage is placed. In the following description, for convenience, only the upper surface of the pallet 1 will be described as a single-sided use type in which the deck surface 2 is used.

Insertion holes 13 for inserting the non-slip material 12 into the deck surface 2 of the pallet 1 at a plurality of locations of the region 11 corresponding to each fork insertion portion 3 (4 locations in each region 11 in FIG. 1 for a total of 8 locations). (See FIG. 4) is provided. The insertion hole 13 and the anti-slip material 12 are shown in detail in FIGS. 2 to 5.

That is, in the insertion hole 13, as shown in FIGS. 2 to 5, the ribs 14 intersect in a cross shape in the region 11 corresponding to the fork insertion portion 3 of one pallet half body 1a constituting the deck surface 2. It is formed by penetrating the part in the vertical direction. Further, as shown in FIG. 4, the insertion hole 13 has an opening 21 on the deck surface mounting side, a step portion 22 on the deck surface mounting side, an intermediate hole portion 23, and a step portion on the deck surface fork insertion portion side. 24 and an opening 25 on the deck surface fork insertion portion side are provided.

The intermediate hole portion 23 includes a first intermediate hole portion 23a located closer to the opening 21 on the deck surface mounting side, a second intermediate hole portion 23b located closer to the opening 25 on the deck surface fork insertion portion side, and a first intermediate portion. It has a third intermediate hole portion 23c located between the hole portion 23a and the second intermediate hole portion 23b. The inner diameter d1 of the first intermediate hole portion 23a and the inner diameter d2 of the second intermediate hole portion 23b are both constant in the center line direction (vertical direction), but the inner diameter d1 of the first intermediate hole portion 23a is the second intermediate. It is larger than the inner diameter d2 of the hole 23b (d1> d2). The inner diameter of the third intermediate hole portion 23c coincides with the inner diameter d1 of the first intermediate hole portion 23a at a portion adjacent to the first intermediate hole portion 23a, and gradually decreases as the distance from the first intermediate hole portion 23a increases, and the second intermediate portion The portion adjacent to the hole portion 23b coincides with the inner diameter d2 of the second intermediate hole portion 23b.

The opening 21 on the deck surface mounting side has a circular shape in a plan view, and its inner diameter d3 is larger than the inner diameter d1 of the intermediate hole portion 23 (specifically, the first intermediate hole portion 23a) (d3> d1). Due to this difference in inner diameter, a step portion 22 on the deck surface mounting side is formed between the opening 21 on the deck surface mounting side and the intermediate hole portion 23.

Further, the opening 25 on the deck surface fork insertion portion side is also circular in a plan view, and its inner diameter d4 is larger than the inner diameter d2 of the intermediate hole portion 23 (specifically, the second intermediate hole portion 23b) (d4> d2). Due to this difference in inner diameter, a step portion 24 on the deck surface fork insertion portion side is formed between the opening 25 on the deck surface fork insertion portion side and the intermediate hole portion 23.

The non-slip material 12 is inserted (press-fitted) into the insertion hole 13 from above and mounted in a penetrating state. The non-slip material 12 is a cylindrical material having a drain hole 31 along the center line, and is made of rubber.

Further, as shown in FIGS. 4 and 5, the anti-slip material 12 has an upper flange 32 at the upper end and a lower flange 33 at the lower end. When the anti-slip material 12 is inserted into the insertion hole 13, and thus in the mounted state, the upper flange 32 is on the step portion 22 on the deck surface mounting side of the insertion hole 13, and the lower flange 33 is on the deck surface fork insertion portion of the insertion hole 13. By contacting each of the stepped portions 24 on the side, the anti-slip material 12 is prevented from falling out of the insertion hole 13. Further, the upper end portion and the upper flange 32 of the anti-slip material 12 project above the upper surface (that is, the deck surface 2) of the pallet half body 1a by a predetermined dimension, whereby the object placed on the deck surface 2 is placed. It is designed to prevent skidding. Further, the lower end portion and the lower flange 33 of the anti-slip material 12 project downward by a predetermined dimension from the lower surface of the pallet half body 1a (that is, the upper inner surface of the fork insertion portion 3), whereby the lower end portion and the lower flange 33 are inserted into the fork insertion portion 3. The upper surface of the fork is in contact with the lower end of the anti-slip material 12 and the lower flange 33 to prevent the pallet 1 from skidding with respect to the fork. The outer diameter of the intermediate portion between the upper flange 32 and the lower flange 33 of the anti-slip material 12 is set to be smaller than the inner diameter of the intermediate hole portion 23 of the insertion hole 13, and the anti-slip material with respect to the insertion hole 13. In the mounted state of 12, a space is formed between the insertion hole 13 and the non-slip material 12, whereby the frictional resistance when the non-slip material 12 is inserted into the insertion hole 13 from above and mounted is reduced. I try to do it.

Further, on the inner peripheral surface of the insertion hole 13, a groove 41 is formed so that water accumulated between the anti-slip material 12 and the insertion hole 13 can be discharged to the outside of the insertion hole 13 in the inserted state of the anti-slip material 12. There is. The groove portions 41 are formed at two locations corresponding to the ribs 14 facing each other and extending in one direction with the center line of the insertion hole 13 interposed therebetween. In particular, in the present embodiment, as can be seen from FIGS. 1 and 2, the groove portion 41 is formed in a direction orthogonal to the longitudinal direction (extension direction) of the fork insertion portion 3.

The groove portion 41 has a semicircular shape in a plan view, and is continuously formed so as to straddle between the opening 21 on the deck surface mounting side of the insertion hole 13 and the opening 25 on the deck surface fork insertion portion side. However, the depth of the groove 41 is not constant. That is, the depth of the groove 41 gradually decreases as the distance from the opening 21 along the center line of the insertion hole 13 at the portion of the insertion hole 13 near the opening 21 on the deck surface mounting side, and the depth of the deck surface fork of the insertion hole 13 It becomes constant when the opening 25 on the insertion portion side is approached within a predetermined dimension.

Next, to explain the action and effect of the pallet 1, even when water has entered between the insertion hole 13 of the deck surface 2 and the non-slip material 12 during cleaning of the pallet 1, the water is still inside the insertion hole 13. It is discharged to the outside of the insertion hole 13 through the groove 41 formed on the peripheral surface, and does not collect between the non-slip material 12 and the insertion hole 13. As a result, it is possible to prevent the mounted object placed on the deck surface 2 from getting wet by the water accumulated between the anti-slip material 12 and the insertion hole 13 during use after cleaning.

In particular, in the case of the present embodiment, the groove portion 41 is continuously formed so as to straddle between the opening 21 on the deck surface mounting side of the insertion hole 13 and the opening 25 on the deck surface fork insertion portion side. Therefore, when water enters between the insertion hole 13 of the deck surface 2 and the non-slip material 12 during cleaning of the pallet 1, the water reaches the opening 21 on the deck surface mounting side of the insertion hole 13 due to its own weight. Of the openings 25 on the deck surface fork insertion portion side, the groove 41 facing the lower opening (opening 25 on the deck surface fork insertion portion side in FIG. 4) is smoothly and quickly discharged to the outside of the insertion hole 13. This makes it possible to reliably prevent water from accumulating between the anti-slip material 12 and the insertion hole 13.

In addition, since the groove 41 is formed on the inner peripheral surface of the insertion hole 13, the frictional resistance when the anti-slip material 12 is inserted into the insertion hole 13 is reduced, so that the insertion is facilitated.

Here, it is preferable that the groove portion 41 is formed in a direction orthogonal to the longitudinal direction of the fork insertion portion 3 as in the present embodiment. In this case, when the anti-slip material 12 is pushed by the claws of the fork, it is possible to prevent the anti-slip material 12 from entering the groove 41 and causing damage such as neck breakage.

Further, in the case of the present embodiment, the intermediate hole portion 23 of the insertion hole 13 is located closer to the opening 25 on the deck surface fork insertion portion side and the first intermediate hole portion 23a located closer to the opening 21 on the deck surface mounting side. It has a second intermediate hole portion 23b and a third intermediate hole portion 23c located between the first intermediate hole portion 23a and the second intermediate hole portion 23b. The inner diameter d1 of the first intermediate hole portion 23a and the inner diameter d2 of the second intermediate hole portion 23b are both constant in the center line direction (vertical direction), but the inner diameter d1 of the first intermediate hole portion 23a is the second intermediate. It is larger than the inner diameter d2 of the hole 23b (d1> d2). The inner diameter of the third intermediate hole portion 23c coincides with the inner diameter d1 of the first intermediate hole portion 23a at a portion adjacent to the first intermediate hole portion 23a, and gradually decreases as the distance from the first intermediate hole portion 23a increases, and the second intermediate portion The portion adjacent to the hole portion 23b coincides with the inner diameter d2 of the second intermediate hole portion 23b.

In such a configuration of the intermediate hole portion 23 of the insertion hole 13, the inner diameter d1 of the first intermediate hole portion 23a is made larger than the outer diameter of the lower flange 33 of the anti-slip material 12, so that the anti-slip material is formed at the time of insertion. 12 can be positioned and self-supporting. Further, the second intermediate hole portion 23b sufficiently secures surface contact with the anti-slip material 12 and disperses the force, so that damage such as neck breakage can be prevented.

The present invention is not limited to the above embodiment, but includes various other forms. For example, in the above embodiment, the groove portions 41 are formed at two locations on the inner peripheral surface of the insertion hole 13, respectively, but in the present invention, the groove portions 41 are provided at only one location on the inner peripheral surface of the insertion hole 13, or the insertion hole 13 is provided. Grooves 41 may be provided at a plurality of locations other than the two locations on the inner peripheral surface of the above.

Further, in the above-described embodiment, when the groove portion 41 is formed on the inner peripheral surface of the insertion hole 13, the groove portion 41 is provided with the opening 21 on the deck surface mounting side of the insertion hole 13 and the opening 25 on the deck surface fork insertion portion side. Although it is formed continuously across the space, in the present invention, the groove 41 is formed between the deck surface mounting side of the insertion hole 13 and the deck surface fork insertion portion side in the circumferential direction of the inner peripheral surface of the insertion hole 13. It may be formed at a position deviated by, for example, 45 °. Even in this case, the deck surface mounting side and the deck surface fork insertion portion side of the groove portion 41 communicate with each other through the gap between the insertion hole 13 and the anti-slip member 12, as in the case of the above embodiment. Can produce the effects of.

Further, in the case of the pallet 1 using one side, the present invention may form a groove only on the deck surface fork insertion portion side of the inner peripheral surface of the insertion hole 13. In this case, even when water enters between the insertion hole 13 of the deck surface 2 and the anti-slip material 12 during cleaning of the pallet 1, the water is discharged to the outside of the insertion hole 13 through the groove due to its own weight. Therefore, it does not collect between the anti-slip material 12 and the insertion hole 13.

In addition, in the above-described embodiment, the non-slip material is formed at a portion where the ribs 14 intersect in a cross shape in the region 11 corresponding to the fork insertion portion 3 of one pallet half body 1a constituting the deck surface 2 of the pallet 1. An insertion hole 13 for inserting the 12 is provided so as to penetrate in the vertical direction, but the present invention is not limited to this, and the rib is formed in the region 11 corresponding to the fork insertion portion 3 on the deck surface 2 of the pallet 1. An insertion hole 13 for inserting the non-slip material 12 may be provided so as to penetrate in the vertical direction at a position other than the portion where the 14 intersects in a cross shape.

Further, in the present invention, an insertion hole 13 for inserting the anti-slip material 12 may be provided in a portion other than the region 11 corresponding to the fork insertion portion 3 in the deck surface 2 of the pallet 1. In this case, on the inner peripheral surface of the insertion hole 13, water that collects between the anti-slip material 12 and the insertion hole 13 in the inserted state of the anti-slip material 12 is applied to the lower surface side of the pallet (anti-deck) outside the insertion hole 13. A groove that can be discharged may be formed on the surface side).
