Abstract

PURPOSE:To obtain a standardized transportation pallet having a proper degree of strength by forming the bottom of a lattice groove into a slightly swollen shape and by providing reinforcement ribs in a mount. CONSTITUTION:A transportation pallet is molded when a synthetic resin sheet of 4-5mm thickness is heated and subjected to vacuum molding. As materials for synthetic resin, polypropylene or polyethylene is suitable. A peripheral wall is formed into a trapezoid shape, the upper edge of the peripheral wall is folded back inward to constitute an erected periphery 2 and, inside the periphery 2, the top surface of a mount is provided in a position slightly lower than the upper edge of the periphery 2. A plane lattice groove 3 is provided inside the erected periphery 2 and a trapezoid-shaped mount 4 is provided between grooves. The bottom 5 of the groove 3 is formed into a shape slightly swollen upward in section to enhance the strength of the whole pallet. The top surface 6 of the mount 4 is provided with reinforcement ribs 7 to stiffen the strength of the top surface 6. Fork-inserting holes 9 are formed in the facing peripheral wall 1 and wait 10 of the mount and the fork of the forklift is inserted into the fork-inserting holes 9 so that the pallet is transported.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a synthetic resin transport pallet used for transporting cargo by a forklift.

(Prior Art) Conventionally, the majority of transportation pallets have been made of wood, and each company has different dimensions.

(Problems to be Solved by the Invention) As described above, conventional transportation pallets were made of wood and had different dimensions depending on the manufacturer, so there was a problem that they could not be shared or used for multiple purposes.

In order to solve this problem, standardized transport pallets made of synthetic resin have recently been developed.

Since this synthetic resin transport pallet is injection molded, the mold is expensive and the manufacturing machine is large, which poses a problem in that the pallet cannot be provided at a low price.

The present invention has been made in view of the problems of the conventional pallets described above, and an object of the present invention is to provide a standardized synthetic resin transportation pallet at a low cost.

(Means for Solving the Problems) In order to achieve the above object, the synthetic resin transportation pallet of the present invention is produced by vacuum forming or compression molding a rectangular sheet of synthetic resin with a thickness of about 4 to 5 mm by heating it. It is a pallet for transportation, and the upper edge of the four peripheral walls is folded back so that the inner side thereof is slightly lower to form a raised peripheral edge, and a planar grid-like groove is formed inside this raised peripheral edge, and the grooves are positioned between these grooves. A trapezoidal platform is formed, the bottom of the groove is slightly bulged upwards, a reinforcing rib is formed on the top surface of the platform, and a fork is provided on the opposing circumferential wall and the parallel wall of the platform. It is characterized by having an insertion hole formed therein.

(Embodiments) The present invention will be described in detail below based on preferred embodiments shown in the drawings. The drawing shows a synthetic resin transportation pallet of the present invention, which is formed by heating a synthetic resin sheet with a thickness of 4 to 5 mm and then vacuum forming it. Moreover, polypropylene or polyethylene is suitable as the material for the synthetic resin.

In the figure, reference numeral 1 indicates the four peripheral walls, which are slightly inclined so that the whole has a trapezoidal shape. The upper edges of these four peripheral walls are folded back inward to form a standing peripheral edge 2, and inside this peripheral edge 2, the upper surface of a pedestal, which will be described later, is provided at a position slightly lower than the upper edge of the peripheral edge 2.

In the figure, reference numeral 3 denotes a planar lattice-shaped groove provided inside the upright peripheral edge 2, and a trapezoidal platform 4 is provided between these grooves. The bottom portion 5 of the groove 3 has a cross-sectional shape that is slightly bulged upward, thereby increasing the strength of the entire pallet.

A reinforcing rib 7 is provided on the upper surface 6 of the base portion 4. The shape of the reinforcing rib 7 is preferably a cross shape in plan view as shown in FIG. Any material that can reinforce the strength of the upper surface 6 of 4 may be used. In the embodiment shown in FIGS. 3 and 4, this reinforcing rib 7 is formed as a groove on the upper surface 6, but in the embodiment shown in FIG.
It is a convex strip. Further, in the embodiment shown in FIG. 4, a reinforcing plate 8 is placed on the entire inner side of the upright peripheral edge 2. This reinforcing plate may be made of synthetic resin, but it may also be made of rubber belts bonded to this synthetic resin plate at intervals.

Further, reference numeral 9 in the figure indicates a fork insertion hole formed in the opposing peripheral wall 1 and the wall 10 of the platform parallel to the peripheral wall.

The pallet of the present invention having the above-mentioned structure is transported by inserting the forks of a forklift into the fork insertion holes, similarly to known pallets. Therefore, objects are placed on the pallet, but in the case of the embodiments shown in FIGS. In some cases, the reinforcing ribs have a convex shape, so that objects of a size that can be stored inside the convex shape can be transported.

(Effects of the Invention) Like soft soil, the pallet of the present invention has a slightly swollen bottom part of the lattice groove and a reinforcing rib on the base part, so
A standardized transportation pallet having appropriate strength can be provided by vacuum forming or compression molding a synthetic resin sheet with a thickness of about 5 mm, and the pallet can be provided at a low cost.
