Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin pallet, and more particularly to a synthetic resin pallet that can be tightly banded on a load to prevent the load placed on the synthetic resin pallet from collapsing. is there.
[0002]
[Prior art]
Conventionally, an elastic band is inserted into the fork insertion hole of the synthetic resin pallet, and the elastic band is applied to the load placed on the synthetic resin pallet so that the load does not move. ing. Then, the tightening band can be inserted into a rib that is positioned above the entrance of the fork insertion hole and orthogonal to the fork insertion direction so that the tightening band inserted through the fork insertion hole does not move laterally. A synthetic resin pallet is known in which a notch recess is formed, and a tightening band inserted into the fork insertion hole is inserted into the notch recess to suppress lateral movement of the tightening band. (For example, Japanese Patent No. 2889506).
[0003]
[Problems to be solved by the invention]
In the above-described conventional synthetic resin pallet, in order to suppress the lateral movement of the elastic band, a notch recess into which the elastic band can be inserted is formed in a rib orthogonal to the fork insertion direction. For this reason, there is a problem that the strength and rigidity in the vicinity of the fork insertion hole of the synthetic resin pallet are lowered. When a fork is inserted into the fork insertion hole and the synthetic resin pallet on which the load is placed is lifted, a large load is applied near the fork insertion hole of the synthetic resin pallet. If the notched recess is formed in the positioned rib, the strength and rigidity in this portion are lowered, which is a particularly serious problem.
[0004]
An object of the present invention is to solve the problems of the above-described conventional synthetic resin pallet.
[0005]
[Means for Solving the Problems]
In the present invention, in order to achieve the above-described object, a plurality of fork insertion direction ribs along a fork insertion hole and a plurality of inter-girder ribs perpendicular to the fork insertion direction rib are vertically provided on the lower surface of the deck portion. In the synthetic resin pallet, a pair of opposed forks along the fork insertion hole is inserted between the ribs between the beams closest to the peripheral part of the deck part and the peripheral part of the deck part. A direction rib is formed so as to bridge the inter-girder rib closest to the peripheral portion of the deck portion and the peripheral portion of the deck portion, and the pair of opposed fork insertion direction ribs. , Without forming a notch recess in the inter-girder rib and forming a bulging portion extending downward over the elastic band inserted between the pair of opposing fork insertion direction ribs It is.
[0006]
【Example】
Examples of the present invention will be described below. However, the present invention is not limited to these examples as long as the gist of the present invention is not exceeded.
[0007]
As an example, the synthetic resin pallet shown in FIG. 1 includes an elongated cylindrical side girder portion 2 formed along one opposite side of the deck portion 1 on which a load is placed, and a relative The side girder part 2 has an elongated cylindrical intermediate girder part 3 formed substantially parallel to the side girder part 2 at the middle part thereof, and the side girder part 2 and the intermediate girder part 3 A fork insertion hole 4 into which a fork of a forklift can be inserted is formed.
[0008]
A plurality of fork insertion direction ribs 5 are suspended along the fork insertion hole 4 on the lower surface of the deck portion 1 positioned above the fork insertion hole 4. The inter-spar ribs 6 are provided so as to be orthogonal to the insertion direction ribs 5.
[0009]
Of the fork insertion direction ribs 5 that are suspended along the fork insertion hole 4 on the lower surface of the deck portion 1, a pair of opposing fork insertion direction ribs 5 a that are suspended at the center of the fork insertion hole 4 When the elastic band B is disposed between the fork insertion direction ribs 5a, a bulging portion 5a1 extending downward beyond the elastic band B is formed.
[0010]
As described above, by forming the bulging portions 5a1 extending downward in the pair of opposing fork insertion direction ribs 5a that are suspended in the center of the fork insertion hole 4, the distance between the fork insertion direction ribs 5a is increased. In addition, when the elastic band B is disposed, as shown in FIGS. 3 and 4, the elastic band B is located above the bulging portion 5a1 of the fork insertion direction rib 5a. The lateral movement of the elastic band B is suppressed.
[0011]
Further, in this embodiment, unlike the conventional synthetic resin pallet, the notch is not formed in the rib located above the entrance of the fork insertion hole, so the strength in the vicinity of the fork insertion hole 4 The rigidity is not lowered, and therefore the strength and rigidity of the synthetic resin pallet can be prevented from being lowered.
[0012]
In the embodiment described above, the fork insertion direction rib 5a bridged between the inter-spar rib 6 closest to the peripheral portion 1a of the deck portion 1 and the peripheral portion 1a of the deck portion 1 Although the example which formed the extended bulging part 5a1 is shown, the bulging part 5a1 extended below can also be formed in the other fork insertion direction rib 5. FIG.
[0013]
Further, in the above-described embodiment, an example in which the bulging portion 5a1 is formed on the pair of opposed fork insertion direction ribs 5a suspended from the center portion of the fork insertion hole 4 is shown. The bulging part 5a1 can also be formed in a pair of opposing fork insertion direction ribs 5 that are suspended from the center part of the insertion hole 4.
[0014]
Furthermore, in the above-described embodiment, a so-called two-way synthetic resin pallet is shown, but the present invention can also be applied to a four-way synthetic resin pallet.
[0015]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0016]
The strength and rigidity in the vicinity of the fork insertion hole are not lowered, and therefore, the strength and rigidity of the synthetic resin pallet can be prevented from being lowered.
