Description

Description: TECHNICAL FIELD The present invention relates to a prefabricated pallet for a forklift that serves as a luggage base plate used when carrying stacked luggage by a forklift.

[Problems to be Solved by Prior Art and Invention]

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

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

Therefore, it has been proposed to divide the pallet into several pieces so that they can be manufactured with a small molding machine, and then join them together.However, if you simply join the pallets in parallel, the fork holes will be perpendicular to the dividing direction. However, in the case of a four-way pallet, the other fork hole is parallel to the dividing direction, and there is a drawback that the strength against load is reduced.

Therefore, the inventor has formed a connecting convex portion 3 and a connecting concave portion 4 near the ends of the dividing surface 2 of the plastic divided pallet body 1 obtained by dividing the square pallet body in the diagonal direction, and the connecting convex portion 3 is formed. The portion 3 and the connecting concave portion 4 are provided in a male and female relationship,
Further, a fork insertion hole 5 is provided between the connecting convex portion 3 and the connecting concave portion 4 of the divided pallet body 1, and the plural divided pallet bodies 1 having the same shape are mutually connected by the connecting convex portion 3 and the connecting concave portion 4. We have developed an assembly type forklift pallet that can be assembled and molded into a plastic square pallet body a having a fork through hole 5 into which the forks 6 of the forklift 11 can be inserted from all sides.

However, in this case the finished product will be square, so
The inventor further succeeded in mass-producing a rectangular product by joining the additional pallet body b with the square pallet body a as a matrix, and completed the present invention.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A triangular pallet body is divided in a diagonal direction. A triangle-shaped connecting convex portion 3 having a right apex angle is formed on one side of the divided surface 2 of the divided pallet body 1 near both ends, and on the other side is a triangular shaped connecting shape. Forming the concave portion 4 for connecting, the connecting convex portion 3 and the connecting concave portion 4 of the corresponding divided pallet bodies 1 adjacent to each other are provided in the male and female fitting structure, and the connecting convex portion 3 and the connecting convex portion 3 which are fitted to each other are connected.
