Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin pallet on which articles are placed and used for transportation, storage, and the like.
[0002]
[Prior art]
Conventionally, a two-way or four-way synthetic resin pallet having a fork insertion port into which a hand forklift can be inserted is known.
[0003]
[Problems to be solved by the invention]
Hand forklift wheels run on the ribs formed inside the plastic pallet, but in conventional plastic pallets, the hand forklift wheels drop into the gap between the ribs and move smoothly. There was a problem that running of a hand forklift was hindered.
[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]
The present invention, in order to achieve the above object, the deck board positioned on the upper and lower surfaces of the fork insertion holes, there a fork entry direction ribs and the synthetic resin pallet forks orthogonal direction ribs are formed so as to intersect In order to reduce the amount of sagging in the gap between the fork orthogonal ribs of the front wheel of the hand forklift, substantially triangular ribs are formed on both side surfaces of the fork orthogonal ribs.
[0006]
【Example】
First, a synthetic resin pallet P as an example will be described with reference to FIG.
[0007]
Reference numeral 1 denotes an upper deck board, 2 denotes a lower deck board, and the upper deck board 1 and the lower deck board 2 are formed in the same shape by injection molding or the like. The upper deck board 1 and the lower deck board 2 have end girders 1a and 2a formed in parallel along one opposite side, parallel to the end girders 1a and 2a, and at the center. The formed central girders 1b and 2b are formed, and the end faces of the end girders 1a and 2a and the central girders 1b and 2b are welded and joined to form a synthetic resin pallet P, respectively. Two fork insertion ports 3 are formed between the end girders 1a and 2a and the central girders 1b and 2b, and a so-called two-way synthetic resin pallet P is formed.
[0008]
In order to facilitate the entry and exit of the front wheel f2 attached to the tip of the fork f1 of the hand forklift F to the fork insertion port 3, inclined surfaces 1c and 2c are formed at the entrance of the fork insertion port 3. Has been. In the present embodiment, a so-called double-sided synthetic resin that can be used even when the upper deck board 1 is placed downward and the lower deck board 2 is placed upward from the state shown in FIG. 1 or FIG. Since it is formed on the pallet P, inclined surfaces 1 c and 2 c are formed at the entrances of the fork insertion ports 3 of both the upper deck board 1 and the lower deck board 2.
[0009]
The upper deck board 1 and the lower deck board 2 positioned on the upper and lower surfaces of the fork insertion port 3 are provided with ribs (hereinafter simply referred to as “fork entry direction ribs”) 4 along the entry direction of the fork f1 of the hand forklift F. Ribs orthogonal to the entry direction of the fork f1 of the forklift F, that is, ribs orthogonal to the fork entry direction rib 4 (hereinafter simply referred to as “fork orthogonal direction ribs”) 5 are formed so as to intersect each other.
[0010]
In one embodiment of the present invention, as shown in FIG. 3, the fork entry direction rib located on the traveling part is mounted with the front wheel f2 attached to the tip of the fork f1 of the hand forklift F. The interval 4a is configured to be narrower than the width w of the front wheel f2. By configuring in this way, the front wheel f2 can travel on the fork entry direction rib 4a so as to travel on the rail, so that the front wheel f2 is between the fork entry direction ribs 4 or in the direction perpendicular to the fork. The problem that the hand forklift F cannot smoothly enter and exit the fork insertion port 3 of the fork f1 by falling between the ribs 5 is solved, and the hand forklift F enters the fork insertion port 3 of the fork f1. And the exit can be performed smoothly and easily.
[0011]
In the above-described embodiment, the front wheel f2 attached to the tip of the fork f1 of the hand forklift F is placed, and the interval between the fork entry direction ribs 4a located in the traveling portion is narrower than the width w of the front wheel f2. Although the example which comprised is shown, instead of narrowing the space | interval of the fork approach direction rib 4a located in the driving | running | working part, the space | interval of the fork orthogonal direction rib 5 is made into the fork insertion port 3 of the fork f1 of the hand forklift F. It can also be narrowed so that entry and exit are smooth and easy. In this case, in any case, the wheel f2 falls into the gap between the fork orthogonal ribs 5, but by reducing the interval between the fork orthogonal ribs 5, the gap between the fork orthogonal ribs 5 of the wheel f2 is reduced. Therefore, compared with a conventional synthetic resin pallet, the fork f1 of the hand forklift F can enter and leave the fork insertion port 3 smoothly and easily.
[0012]
In the embodiment shown in FIG. 4, as in the above-described embodiment, the distance between the fork orthogonal ribs 5 is set so that the entry and exit of the hand forklift F into the fork insertion port 3 of the fork f1 is smooth, and Instead of being narrowed, a substantially triangular rib 6 extending in the direction of the fork f1 is formed on both side surfaces of the fork orthogonal direction rib 5 so that the interval between the fork orthogonal direction ribs 5 is narrowed. It is. By configuring in this way, the amount of depression of the wheel f2 into the interval between the fork orthogonal ribs 5 is small, and therefore the fork f1 of the hand forklift F enters the fork insertion port 3 as compared with the conventional synthetic resin pallet. And the exit can be performed smoothly and easily.
[0013]
Although the embodiment of the present invention has been described using a two-way synthetic resin pallet as an example, it should be understood that the configuration of the present invention can also be applied to a four-way synthetic resin pallet. Can do.
[0014]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0015]
Since the interval between the ribs in the fork entry direction is narrower than the width of the front wheel of the hand forklift, it is possible to smoothly and easily enter and exit the fork insertion port of the fork of the hand forklift.
[0016]
Since the distance between the fork orthogonal ribs is reduced, the amount of drop in the gap between the fork orthogonal ribs on the front wheel of the hand forklift can be reduced. , Smooth and easy.
[0017]
Since the substantially triangular ribs are formed on both side surfaces of the fork orthogonal direction rib, the amount of drop in the gap between the fork orthogonal direction ribs on the front wheel of the hand forklift can be reduced. The entrance and exit from the insertion port can be performed smoothly and easily.
