  • Patent number: 6237509
    Abstract: A synthetic resin pallet capable of enhancing a strength against a bending force acting in a direction right-angled to a loading surface without an increase in weight of the whole pallet. The synthetic resin pallet is constructed such that pallet constructive members taking configurations of the pallet being divided into upper and lower members are formed by, e.g., injection molding, then set facing to each other and integrally welded. A reinforced tape using a fiber reinforced material which is bendable is attached for reinforcement by the heat welding inside a groove formed on a surface of any one or both of the pallet constructive members in order to resist a bending force acting in a direction orthogonal to the surface thereof.

  • Patent number: 5967057
    Abstract: A synthetic resin pallet including a top board, a bottom board disposed opposite to the top board, and a plurality of cylindrical blocks for connecting the two boards. A fork entry port is formed between the blocks. The synthetic resin pallet is manufactured by making one pallet constructive member and another pallet constructive member face to each other. The one pallet constructive member includes the board and cylindrical block constructive members integrally formed on the inside of the board. The other pallet constructive member includes the board and block constructive member integrally formed on the inside of the board. Reinforcing ribs are formed lengthwise and crosswise on the inside of the surface of at least one pallet constructive member. The reinforcing ribs include surface reinforcing ribs formed lengthwise and crosswise on the inside of the surface of the synthetic resin pallet. Hollowed portions are formed in inner parts of at least some of the surface reinforcing ribs.
