Abstract

PURPOSE:To obtain a lightweight, durable pallet for use on forklift at low costs by a method wherein a plurality of separate pallets of the same shape are interengaged by the locking projections and recesses to form a plastic rectangular pallet body having through holes for a fork on all sides. CONSTITUTION:A rectangular pallet is composed of the four pallets 1, 1', 1'' and 1''' triangularly separated by the two intersecting diagonal lines of the pallet, each of which is provided with two locking projections 3 on both the upper and lower ends of the left sloping side thereof and two locking recesses 4 on both the upper and lower ends of the right sloping side. In this example, the locking projections 3 are formed by a combination of the one projecting from the middle of the side face and the one projecting from both the upper and lower ends thereof and the locking recesses 4 are formed by a combination of the one recessed in the middle of the side face and the one recessed in both the upper and lower end thereof. The locking projections 3 and the locking recesses 4 are interengaged with the vertical angle parts 4 of the four separate pallets 1, 1', 1'' and 1''' joined together to form a plastic rectangular pallet (a) into which the fork of a forklift can be inserted from all sides.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pallet for a prefabricated forklift, which serves as a cargo base plate used when a forklift transports stacked cargo.

[Problems to be solved by conventional technology and invention]

The size of a forklift pallet is determined according to the size of the forklift and the size of the cargo.

In order to manufacture a normal-sized pallet by plastic molding, a very large and expensive molding machine is required, which increases the cost accordingly.

For this reason, it has been proposed to divide the pallet into several parts, mold them, and join them together so that they can be manufactured using a small molding machine. However, in the case of a four-way pallet, the other fork hole is parallel to the dividing direction, which has the disadvantage that the strength against loads is reduced.

The present invention provides a pallet for a prefabricated forklift that solves these drawbacks.

[Means to solve the problem]

The present invention will now be described in detail with reference to the accompanying drawings.

A connecting protrusion 3 and a connecting recess 4 are formed near the end of the dividing surface 2 of a divided pallet body 1 obtained by dividing a rectangular pallet body in the diagonal direction. are provided in a male and female relationship, and the connecting convex portion 3 of the divided pallet body 1
A fork insertion hole 5 is provided between the connecting convex portion 3 and the connecting concave portion 4, and the plurality of segmented pallet bodies 1 of the same shape are fitted and connected to each other by the respective connecting convex portions 3 and the connecting concave portions 4, and the fork of the forklift 11 is inserted from all sides. A plastic rectangular pallet body a having a fork insertion hole 5 into which a fork 6 can be inserted.
The present invention relates to a pallet for an assembled forklift, characterized in that it is assembled and molded.

Two divided pallet bodies 1 and 1 divided into two by one diagonal line
The present invention relates to a pallet for a prefabricated forklift according to claim 1, which comprises:

Claim 1rJ consisting of four divided pallet bodies 1, 1°, 1”, and 1° divided into four parts by two intersecting diagonal lines
ii) This relates to a self-mounted assembly type forklift pallet.

[Effect]

FIG. 7 shows two divided pallet bodies 1. - When the connecting protrusion 3 and the connecting recess 4 are fitted into each other with 1° facing each other,
A plastic rectangular pallet body a is formed into which the forks 6 of a forklift 11 can be inserted from all sides.

Figure 1.8 shows four divided pallet bodies 1, 1°, 1°,
1''' with their apex angles abutting each other and fitting the connecting protrusion 3 and the connecting recess 4 into each other, a plastic rectangular pallet body a into which the forks 6 of the forklift 11 can be inserted from all sides is formed. It is formed.

〔Example〕

Fig. 7 shows that in the case of two triangular divided pallet bodies 1.1° in which a rectangle is divided into two diagonally, a connecting protrusion 3 is provided near one end of the long side, and a connecting recess 4 is provided near the opposite end. .

The shape of the connecting convex portion 3 and the connecting recess 4 is a triangular shape obtained by dividing a square into two.

Figure 1.8 shows that in the case of a four-triangular divided pallet 1", 1, and 1", which is a rectangle divided into four quarters by two intersecting diagonal lines, there are two connecting convex parts at both the upper and lower ends of the left oblique side. 3, and two connecting recesses 4 are provided at both upper and lower ends of the right oblique side.

In this case, as shown in FIG. 4, the connecting convex part 3 is a combination of a type that protrudes from the middle and a type that protrudes on both upper and lower sides.
Similarly, the connection recess 4 is a combination of a type recessed in the middle and a type recessed on both upper and lower sides.

The shape of the connecting convex portion 3 and the connecting recess 4 is a triangular shape obtained by dividing a square into two.

In the figure, reference numeral 7 denotes a bolt hole provided in the connecting convex portion 3, and 8 denotes a bolt hole provided in the four connecting portions 4. The bolt holes 7 and 8 are bored at matching positions.

9 is a connecting bolt, 9゛ is a bolt receiving recess, 10 is a part of the artificial tipper, and 13 is a window hole and a cut-out part to reduce weight, and we have devised various ways to improve strength and balance. arranged,
The cut-out part 13 has one side cut out from the top and bottom so as not to hinder the formation of the fork insertion hole 5, and the middle part is made into a convex wall B', and the other part is made into an upper and lower double wall, and a fitting part is formed in between. Although a case is shown in the figure, the fitting portions 13'' may be simply provided on one side of the upper and lower sides and engaged with each other at different levels.

Further, in the bottom part of the fork insertion hole 5 in the drawings except for the entrance part, a bottom crosspiece 14 with a window hole is formed only in the middle, but both sides of the bottom crosspiece 14 are open.

Note that the symbol is a drainage hole designed to prevent water from accumulating inside, and these detailed structures are precisely molded using polypropylene resin or polyethylene resin.

〔Effect of the invention〕

Since the present invention is configured as described above, a plastic rectangular pallet body that can be inserted on all four sides can be produced by mass producing split pallet bodies having the same shape and structure using one plastic mold, and by assembling two or four pieces of these divided pallet bodies. It exhibits excellent features that allow it to provide lightweight, durable pallets for assembled forklifts that do not rot or rust at a low cost, and are mass-produced.
