Abstract

PROBLEM TO BE SOLVED: To obtain a lightweight fire-retardant palette preventing the damage of a cargo and the injury of a worker caused by the knot, grain or nail of a wooden palette and generating no swelling caused by humidification by forming a palette main body from a single member of plastic composed of a mixture of polyethylene and polypropylene. SOLUTION: The main body of a palette is formed from a single member obtained by the injection molding of plastic composed of a mixture of polyethylene and polypropylene. The main body has a flat quadrilateral part 3 having wall thickness of a certain degree and a series of vertical square pillar-shaped parts 5, 6 are provided to one side surface of the main body in a protruding state in mutually parallel and opposed relationship and gaps 7 for permitting the introduction of the member of a machine drawing up the cargo arranged on the upper surface 8 of the main body are formed between the square pillar- shaped parts 5, 6. Regular or irregular through-holes are bored in the side surface 8 of the flat quadrilateral part 3 not only to prevent the slide of a commodity but also to reduce a wt.

Description

Detailed Description of the Invention

The present invention relates to a pallet for transporting goods.

The pallets of mobile carrier devices currently found on the market consist of a bottom plate formed of a plurality of parallel wooden cross plates supported along their entire length by horizontal plates of wood material. These are assembled by joining with nails.

The pallets according to the invention are formed from a plastic consisting of a mixture of polyethylene and polypropylene forming a single block or structure which offers the following advantages over the current wooden ones.

Since the injection molding apparatus can determine its quantification in terms of the components that make the resistance of the pallet uniform, the pallets formed in this way provide uniform resistance.
In a wooden pallet, the wooden slab may deteriorate because the wood is a material that has knots and grain that make uniform or continuous resistance in the pallet impossible.

Since the pallet of the present invention is manufactured by an injection molding apparatus that reduces the weight of the pallet by at least half, it is possible to significantly reduce the weight.

Since injection molding does not use the nails and protrusions found in conventional wooden pallets, it is possible to prevent scratching of articles loaded on the pallets or damage accidents to an operator who handles the pallets. .

Since the thickness of the supporting surface of the pallet of the present invention can be changed in order to provide sufficient resistance depending on the load loaded on the pallet, it is possible to load a light load or a product on a thin-walled pallet, and Large packages or goods can be loaded on thick pallets or heavy pallets. It is also possible to add reinforcements during injection molding with glass fibers, which definitely give additional resistance.

The continuous surface of the pallet is made rough or granular so that the products supported by it cannot slide.
Further, it is possible to form a through hole which can reduce the weight or the manufacturing cost.

It can be cleaned and washed with soap and detergent during the manufacturing process, and if desired, can also be carried out by the generally known waterless brushing, since water causes the wood to swell or deform. The pallets of the invention can be stored outdoors without any special kind of protection.

Since the pallet of the present invention has a larger surface than a conventional wooden pallet, the trademark or logo of the user is printed with paint, or the trademark or logo is molded and trimmed during the injection molding process. It has the advantage of being disabled.

A mixture of polypropylene and polyethylene, plus some additives, can make the pallets flame resistant and are much safer than the wooden ones currently on the market. It is an excellent advantage.

Humidity and resistance to striking facilitate the handling of the pallet, which is hygienic, well breathable, lightweight and of constant weight, and can be processed in any color.

The pallet of the present invention can vary in its thickness, dimensions and details depending on the application of the load to be loaded in a single piece based on injection molding with the advantages mentioned above.

According to the invention, the pallet is molded from a single-piece plastic body of a mixture of polyethylene and polypropylene.

The pallet of the present invention has a quadrilateral surface,
On its one side, several prismatic projections are provided parallel to the lateral direction at both ends and in the central part, thereby forming a connecting groove for a fork of a lifting device of this kind.

Embodiments of the present invention will be described below with reference to the accompanying drawings so that not only the structure of the pallet of the present invention but also its usefulness and application can be easily understood. The examples are purely illustrative and not restrictive.

The pallet is formed of a unitary body 2 having a quadrilateral portion 3 of some wall thickness.

One side surface 4 of the quadrilateral part 3 has prismatic projection parts 5 and 6.

The prismatic portion 5 is provided at both ends, and the prismatic portion 6 is arranged at the center so that a gap 7 is formed between each of the two parallel prismatic portions 5 and 6 and 5, 6. There is.

The other side 8 of the quadrilateral part 3 forms the support surface of the load.

While the nature of the invention and the manner of carrying it out have been fully described above, modifications can be made in the details thereof without departing from the basic principles of the structure described above and shown in the accompanying drawings.

[0022]

Since the pallet of the present invention is formed by injection-molding plastic, it has uniform resistance, its weight can be reduced, and damage to luggage due to the knots, grain, nails, etc. of the wooden pallet can be prevented. Workers can also be protected from accidents due to these nodes, wood grain, and nails, the thickness and size of the pallet can be selected according to the type of luggage, the luggage can be prevented from slipping, and the manufacturing cost of the pallet can be reduced.
