DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for mounting a non-slip member.

[0002]

2. Description of the Related Art Conventionally, in a pallet made of synthetic resin, a large number of ribs are formed to improve strength.
On the other hand, the pallet is formed with a non-slip member fitting part,
A rubber non-slip member is fitted into the non-slip member fitting portion and attached, and the outer surface of the non-slip member is exposed to the mounting surface of the pallet so that the object to be mounted on the mounting surface does not slip. Was. Japanese Patent Application Laid-Open No. 3-289444 is known as a pallet provided with such a large number of ribs and provided with a non-slip member fitting portion.

In the conventional example disclosed in Japanese Patent Application Laid-Open No. 3-289444, a large number of ribs 4 are provided so as to improve the strength of the pallet 1. A non-slip member fitting portion 6 is shown in FIG. As shown in the figure, the rib 4 is formed integrally at the intersection where the rib 4 intersects.

[0004]

However, in the case where the non-slip member fitting portion 6 is integrally formed in a cylindrical shape at the intersection of the ribs 4 as shown in FIG. 7, the cylindrical non-slip member fitting portion is formed. 6, the linearity of the rib 4 is interrupted, and the rib 4 is partially bent at the non-slip member fitting portion 6 (that is, the non-slip member fitting portion 6).
Was bent at the peripheral wall portion of

When the fork 3 is inserted into the fork insertion hole of the pallet 1, the fork 3 is not inserted into the entire length of the fork insertion hole, and as shown in FIG. It may be inserted only a little further than this, and may be lifted by a fork in this state. In such a case, fork 3 of pallet 1
A portion of the pallet 1 on which a portion ahead of the portion supported by the pallet 1 exerts a force that bends in the direction of the arrow in FIG. 8 due to the weight of the object N placed thereon. The pallet 1 is reinforced so as not to bend downward by a rib 4 provided on the pallet 1, particularly, a rib 4 parallel to the fork insertion direction.

However, in the conventional example in which the non-slip member fitting portion 6 is integrally formed in a cylindrical shape at the intersection of the ribs 4 as described above, the fork insertion direction is formed in the cylindrical non-slip member fitting portion 6. Since the linearity of the ribs 4 parallel to the above is interrupted, there is a problem that the resistance to the force to be deformed is reduced and the ribs 4 are easily deformed. There is a possibility that the rubber non-slip member may come off from the non-slip member fitting portion 6 by slipping off from the mounting surface portion 1 or by deformation of the non-slip member fitting portion 6. For this reason, in order to prevent deformation and make the pallet 1 such that the non-slip member does not come off from the non-slip member fitting portion 6, it is necessary to increase the number of ribs 4 or increase the thickness of the ribs 4. However, there is a problem that the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and the linearity of the rib parallel to the fork insertion direction despite the fact that the non-slip member fitting portion is formed integrally with the rib. It is an object of the present invention to provide a pallet that does not impair the strength of the pallet, does not lower the strength, prevents the pallet from being deformed, and prevents the non-slip member from coming off the anti-slip member fitting portion.

[0008]

In order to achieve the object of the present invention, a pallet of the present invention comprises a plurality of pallets 1 made of synthetic resin, which are parallel to the direction in which the forks 3 are inserted into the fork insertion holes 2. A rib 4a is formed, and a non-slip member fitting portion 6 having at least one end opened to the mounting surface portion 5 is inserted between the ribs 4a parallel to the insertion direction of the fork 3.
And a rib 4a parallel to the insertion direction of the fork 3 is also parallel to the insertion direction of the fork 3 at a portion where the non-slip member fitting portion 6 is integrally connected. It is. With such a configuration, the ribs 4a parallel to the insertion direction of the fork 3 despite the provision of the anti-slip member fitting portion 6 are provided.
Is not impaired, and the bending strength in the longitudinal direction of the rib 4a is not reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings. The pallet 1 is made of synthetic resin. In the embodiment shown in FIGS. 1 to 3, the entire pallet 1 is formed by integral molding of synthetic resin. May be formed separately, and these may be aligned vertically and integrated by welding.

The pallet 1 is provided with a fork insertion hole 2. In the embodiment shown in the accompanying drawings, a pair of fork insertion holes 2 are formed so as to open at the front and rear surfaces of four front, rear, left and right sides of the pallet 1. Although it is formed, another pair of fork insertion holes 2 may be formed to be opened on both left and right sides in addition to this. Since the pallet 1 is formed of a synthetic resin as described above, a large number of ribs 4 are formed to ensure strength. In the embodiment shown in the accompanying drawings, there are roughly two types of ribs 4 as ribs 4, ribs 4 a in a direction parallel to the insertion direction of the forks 3 inserted into the fork insertion holes 2 and ribs 4 b in a direction intersecting the same.

The upper surface or both upper and lower surfaces of the pallet 1 form a mounting surface portion 5 for mounting an object to be mounted. In the embodiment shown in the accompanying drawings, there is shown an example of a so-called double-sided pallet 1 in which both the upper and lower surfaces of the pallet 1 serve as mounting surfaces 5 for mounting objects to be mounted. The object to be mounted can be placed on the mounting surface 5 even if the device 1 is turned upside down.

As shown in FIG. 5, the upper surface and the lower surface of the pallet 1 are each provided with a non-slip member fitting portion 6, and the non-slip fitting portion 6 provided on the upper and lower sides is cylindrical and has one end. The mounting surface 5 on the upper or lower surface of the pallet 1
It is open to. The non-slip member fitting portion 6 located at a position corresponding to the fork insertion hole 2 has a cylindrical other end opened to the fork insertion hole 2.

The non-slip member fitting portion 6 is provided between two ribs 4a parallel to the insertion direction of the fork 3, and is further provided between another two ribs 4b in a direction intersecting with the rib 4a. It is formed integrally with the ribs 4a and 4b. FIG. 4 is an enlarged perspective view showing the positional relationship between the anti-slip member fitting portion 6 and the ribs 4a and 4b. Here, in the present invention, the two ribs 4a parallel to the insertion direction of the fork 3 are also parallel to the insertion direction of the fork 3 even at a portion where the anti-slip member fitting portion 6 is integrally connected.

In the embodiment shown in FIG. 1, some of the ribs 4 are not shown in the drawing, and only a portion indicated by an area B corresponding to the fork insertion hole 2 of the mounting surface portion 5 is shown. Although the ribs 4 are illustrated, the ribs 4 may be exposed in other areas of the mounting surface portion 5 shown in FIGS. 1 and 2, and the mounting surface portion 5 shown in FIGS. The non-slip member fitting portion 6 may be provided in other areas in the same manner as the area indicated by a.

As shown in FIG. 6, a rubber anti-slip member 7 is fitted into the anti-slip member fitting portion 6, and one end surface of the anti-slip member 7 projects slightly from the mounting surface portion 5 and is exposed. The end face is slightly projected into the fork insertion hole 2 and is exposed. The fork 3 of a forklift is inserted into the fork insertion hole 2, lifted and transported with the object placed on the mounting surface 5 of the pallet 1. In this case, the mounted object is prevented from slipping by the anti-slip member 7 exposed on the mounting surface portion 5. Further, the fork 3 comes into contact with the other end of the anti-slip member 7 exposed in the fork insertion hole 2, and the fork 3 is prevented from slipping on the pallet 1.

When the pallet 1 is lifted by inserting the fork 3 into the fork insertion hole 2 as described above, the pallet 1 may be lifted up without hitting the entire length of the fork insertion hole 2 without being inserted. In this case, there is a possibility that a portion of the pallet 1 in front of the portion supported by the fork 3 may bend downward due to the weight of the mounted object and the mounted object may slip, but even in such a case,
In the present invention, the linearity of the rib 4a parallel to the insertion direction of the fork 3 is not impaired despite the provision of the non-slip member fitting portion 6 as described above, The bending strength in the direction does not decrease,
Therefore, it is possible to prevent deformation of the pallet 1 and to prevent the mounted object from slipping. Further, since the pallet 1 can be prevented from being deformed at the non-slip member fitting portion 6, the rubber non-slip member 7 can be prevented from coming off from the non-slip member fitting portion 6.

[0017]

According to the present invention, as described above, in a synthetic resin pallet, a large number of ribs are formed in parallel with the direction in which the fork is inserted into the fork insertion hole, and the ribs are parallel to the direction in which the fork is inserted. At a portion where at least one end portion of the rib is formed integrally with the rib, a non-slip member fitting portion having an opening at the mounting surface portion is provided, and a rib parallel to the insertion direction of the fork integrally forms the anti-slip member fitting portion. Is also parallel to the insertion direction of the fork, so despite forming the anti-slip member fitting part integrally with the rib,
Without impairing the linearity of the rib parallel to the fork insertion direction, there is no decrease in strength, and it is possible to prevent pallet deformation
The object can be prevented from sliding down due to the deformation of the pallet, and the pallet can be prevented from being deformed, so that the non-slip member can be prevented from coming off from the fitting portion of the non-slip member.
