Abstract

PURPOSE:To provide a pallet which is excellent in rigidity and made relatively large when required and smoothly inserted by a fork and prevents such a danger that the pallet drops down from the fork during traveling of a forklift or the like. CONSTITUTION:Girders 3, 3 are parallelly arranged under a loading area 1 composed of parallelly laid plates 2, 2 to form a first support 5. The spaces between the girders 3, 3 are used as first insertion openings 6, 6 of a fork. Girders 7, 7 are parallelly arranged in the direction crossed in right angles with the girders 3, 3 to form a second support. The spaces between the girders 7, 7 are used as second insertion openings 10 of a fork. In this way, the first and second insertion openings 6, 10 of a fork are crossed with each other in three-dimensional directions. And hence, a fork can be smoothly inserted. And since respective supports are assembled in the vertical direction, the rigidity is increased and even a large dimensional pallet can be fabricated and used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hawk, such as a four-way pallet, in which a supporting portion is provided below a loading portion, and a side surface of the supporting portion is formed with a through hole extending from one end to the other end. The present invention relates to a pallet having a plurality of insertion openings.

[0002]

2. Description of the Related Art Conventionally, as a structure of a pallet, a pallet is generally provided with a loading portion on one side or both sides, and a hawk insertion port is formed below the loading portion facing upward in use. As the hawk insertion port, a two-way type and a four-way type as shown in FIG. 3 are used relatively often (J
See IS-Z-0604).

However, the hawk insertion port is usually formed on the side surface of the support portion formed below the loading portion by one or a plurality of parallel through holes extending from one end to the other end.

By the way, as a method of forming the support portion and the fork insertion opening provided therein, as shown in FIG. 3, a plurality of beam members are arranged in the same direction on the lower surface of the loading portion a at intervals. It is not provided as a bearing part b, and each girder material is provided with a fork insertion port d1, d2 and e1, e2, or a loading part, a bearing part, and a backside material made of synthetic resin or fiber reinforced synthetic resin. And a hawk insertion port are integrally formed by an injection molding method or the like.

[0005]

By the way, FIG. 4 is a plan view showing the four-way pallet P shown in FIG. 3 with the loading portion cut away. As described above, in the case of the four-way pallet, as shown in FIG. , Hawk slots d1, d2 and e1, e
Since both 2 are horizontally provided at the same size (depth) from the loading portion a, this hawk insertion port d
The structure is such that 1, d2 and e1, e2 intersect in a plane.

As a result, the support portion b is divided immediately below the loading portion a, and large and small blocks are scattered. Therefore,
There was a constraint that the load-bearing capacity was greatly reduced and the size had to be made smaller than the size that could be adopted in the case of two-way insertion. For example, in the case of a wooden flat pallet, its size is at most about 1.2 m square. Further, it is difficult to manufacture a long product, that is, a product having a rectangular pallet.

Furthermore, as shown in FIG. 3, the hawk f
The tips of 1 and f2 hit the corners of the intersections of the hawk insertion openings d1 and e1 and d1 and e2, and cannot be inserted smoothly. There is also a problem that luggage and pallets are damaged.

The present invention solves the above-mentioned drawbacks of the prior art by providing a plurality of two-way insertable hawk insertion holes such as four-way insertion, and the hawk insertion openings are provided so as to intersect each other. In the pallet, the desired dimensions are not sacrificed due to the load bearing capacity, and
The purpose of the present invention is to provide a hawk that can be inserted smoothly and does not have a risk of falling from the fork while traveling.

[0009]

According to the present invention, "a supporting portion is provided below the loading portion, and a plurality of hawk insertion openings each having a through hole extending from one end to the other end are provided on a side surface of the supporting portion. , "A pallet characterized in that they are formed so as to cross each other three-dimensionally".

That is, by crossing a plurality of hawk insertion openings vertically with each other, the bearing portion forming the insertion openings is prevented from being divided, and thus the size is restricted or the hawk's insertion is restricted. The main idea is to make sure that the insertion is smooth.

The term "hawk fork" as used in the present invention means
Holes for inserting hawk claws of transport machines such as hawk lifts, which consist of a single through hole or a set of parallel through holes according to the number of hawk claws. A formed piece, etc., which can be inserted in two directions, is called one hawk insertion port. Therefore, a four-way insert will have two fork inserts.

In the present invention, the hawk insertion port is
Although it is formed by providing a "through hole" on the side surface of the support portion, as will be described later, the inner wall of this through hole, except for both side surfaces, has an upper surface and a lower surface that are not necessarily continuous wall surfaces. Need not be configured.

In the pallet of the present invention, since the plurality of hawk insertion openings are formed so as to cross over each other, the supporting portion for forming the hawk insertion openings is assumed to have a vertical thickness. Or, it is unavoidable to adopt a structure in which independent supporting portions forming each fork insertion opening are vertically stacked, and therefore, the supporting portions are not divided and the mechanical strength is enhanced. Will be things.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a side view of the same.

In these figures, 1 is a loading section made up of a plurality of slightly thick wooden boards 2, 2 ...
Is the four wooden girder members arranged in parallel and at intervals with the two longitudinal sides 4 and 4 of the loading unit 1 which face each other,
A first support portion 5 is formed by the girder members 3, 3 ..., and each plate 2, 2 ... Forming the cargo portion 1 is formed by the girder members 3, 3 ,.
・ Fixed with fasteners (not shown) such as nails.

Reference numerals 6 and 6 are first fork insertion openings formed by the girders 3, 3 forming the first support portion 5, and therefore, in the longitudinal direction in which the loading portion 1 is opposed to each other. It is made parallel to the two sides 4 and 4 and is formed by a space between the beam members 3 and 3 located on the two sides 4 and 4 and the beam members 3 and 3 adjacent thereto. The first fork insertion ports 6 and 6 are used when the fork lift has two claws.

Reference numerals 7, 7 ... Denote five wooden girder members which are arranged parallel to and spaced apart from each other in the latitudinal sides 8 and 8 of the loading portion 1 and which are spaced apart from each other. A second supporting portion 9 is formed by the members 7, 7 ..., The girder members 7, 7 ... Are fixed to the girder members 3, 3 ,. .

.. are the second fork insertion openings formed by the girder members 7, 7 ... Forming the second support portion 9, and therefore, the loading portion 1 opposes each other. It is parallel to the two sides 8 in the lateral direction and is formed by the space between the girder members 7, 7. The second fork insertion ports 10, 10 ... Are used when the fork lift has four claws. Reference numeral 11 denotes a back surface portion made of a single wooden plate material, and is attached to the girder members 7, 7 ... by a fixing tool such as a nail. This back surface is not always necessary, and another loading portion may be formed instead of the back surface.

Thus, the girders 3, 3, ... And 7, 7 ...
Are vertically crossed over and assembled, and therefore, the first fork insertion opening 6 and the second fork insertion opening 10 are connected.
And will cross over in the vertical direction.

In the pallet as described above, for example, when the hawk lift has two claws, the first hawk insertion port 6,
6 or with 4 claws, second fork insert 1
You can insert claws into 0, 10 ... to perform loading, transporting, and unloading work. At this time, since the first and second fork insertion ports 6 and 10 are independent from each other, troubles such as the tip of the fork of the fork hitting another fork insertion port cannot occur.

In the present invention, the plurality of fork insertion openings are formed so as to cross each other as described above. In the case of the above-mentioned embodiment, the support part provided with the hawk insertion port is constructed by assembling the independent first support part 5 and the second support part 9 forming each hawk insertion port in the vertical direction. The formed example is shown.

When such a structure is adopted, the girder material is made of, for example, wood, so that it is possible to manufacture a product having a considerably large size, and it is relatively easy to reduce the weight. Also, since a large gap can be taken in the vertical direction,
The water permeability effect is also outstanding.

Further, the support portion may be integrally formed with the loading portion or the like as described above. In this case, the support portion needs to be thick in the up-down direction and made of synthetic resin or the like. The inner wall of the through-hole that forms the hawk insertion port becomes a complete partition until it reaches the other end, so that the claws of the hawk can be inserted more smoothly. Further, mass production is possible by injection molding method or the like. However, in this case, it is preferable to appropriately provide a water draining hole from the loading section to the back surface of the pallet.

In any case, since the support portion is not divided, it is possible to obtain one having excellent mechanical strength, especially rigidity. Therefore, it is possible to manufacture long pallets. Conventionally, for example, in the case of a wooden pallet, the limit is 1.2 m square as described above, but in the pallet of the present invention, the lateral direction is 1.2 m, and the longitudinal direction is double 2.4 m.
A rectangular shape is also possible. In the case of this rectangular pallet having the structure of the above-described embodiment, a standard hawk lift (1.5 ton car, claw length = 920 m)
The claw of m) was inserted into the first fork insertion ports 6 and 6 to carry out the work of loading, carrying and unloading, but no trouble occurred.

[0025]

EFFECTS OF THE INVENTION Since the pallet of the present invention is formed so that a plurality of fork insertion openings cross each other,
The support portion for forming the hawk insertion port must be thick in the vertical direction, or the independent support portion forming each hawk insertion port must be vertically stacked. Therefore, the bearing is not divided, and the mechanical strength, especially the rigidity, is enhanced.

Therefore, it is possible not only to manufacture and use a relatively large sized product if desired, to increase the load capacity and to expand the range of applications, but also to facilitate the insertion of the forks and to make the forks even while running. Since there is little danger of falling from the top, there is no damage to the hawk or cargo, workability, transportability,
It has excellent safety.
