Description

This invention relates to a pallet for carrying reusable containers used when transporting goods such as products and articles, and more particularly to a vibration-damping pallet that absorbs vibrations that occur when transporting goods such as precision equipment and works of art. Reusable containers, also known as "folding containers," are used to transport goods such as finished products, semi-finished products, merchandise, and artwork from businesses, factories, logistics centers, supermarkets, drugstores, and other retail stores. These containers can be folded when not in use, becoming roughly the size of a slightly thick board. They offer relatively space-saving storage and can be reused for extended periods. The cargo transported in these reusable containers includes fragile products, goods, and works of art that are susceptible to damage from vibration. Furthermore, precision equipment may experience a decrease in functionality if vibrations are transmitted during transport. Therefore, when transporting fragile items, precision equipment, and works of art, they are placed on vibration-damping pallets to prevent vibrations from being transmitted to the cargo inside the containers. Technologies relating to vibration-damping pallets for placing returnable containers have been proposed. For example, Patent Document 1, "Vibration-Damping Pallet," proposes a vibration-damping pallet comprising a top plate on which the transported goods are placed, and a base portion that supports the top plate via multiple cushioning components. Each component is connected to the base portion by a fixing member detachably fixed to it, and to the top plate portion by a fixing member detachably fixed to it, via cushioning material.

The vibration-damping pallet of the present invention consists of a top plate on which a returnable container for goods such as products or articles to be transported is placed, and a pallet body positioned below the top plate. A vibration absorption mechanism is installed between the top plate and the pallet body to absorb vibrations transmitted from the pallet body. Preferred embodiments of the present invention will be described below with reference to the drawings. The vibration-damping pallet of this invention is used when transporting goods with returnable containers placed on top, but it can also be used in other situations where vibrations during transport are not transmitted to the goods.
