  • Publication number: 20110219643
    Abstract: A method of manufacturing an outsole with an embedded fabric layer includes a preparing step, a forming step and a separating step. The preparing step includes preparing two molds, a fabric layer and a melted plastic material, forming multiple recesses and protruding blocks in the lower mold, setting the depth of each one of the recesses 11, 11A and the height of each one of the protruding blocks at a ratio of 2:1 and dipping the fabric layer in a liquid resin. The forming step includes injecting the melted plastic material into the molds to form an outsole to enable the melted plastic material to fill into the recesses to form multiple non-slip protrusions. The separating step includes cooling the molds, separating the molds and getting the outsole with the embedded fabric layer out of the molds.

  • Publication number: 20080263905
    Abstract: An outsole with an embedded fabric layer has a fabric layer and an outsole. The fabric layer has a top surface and a bottom surface. The outsole has a bottom surface and multiple non-slip protrusions. The bottom surface of the outsole is attached to the top surface of the fabric layer. The non-slip protrusions are formed integrally on the bottom surface of the outsole, extend through the fabric layer and protrude out from the bottom surface of the fabric layer. With the non-slip protrusions, the outsole can provide excellent anti-slip effect and aesthetically pleasing decoration. Additionally, import tariffs on the outsole may be lowered because the shoe is a composite material.

  • Patent number: 6772539
    Abstract: Each shoe in accordance with the present invention has a shoe sole, an upper, reinforcing pieces, a welt and nails. The shoe sole has a top surface, a bottom surface, a round side, slots and reinforcing pieces. The slots are defined through the top surface near the round side of the shoe sole. The reinforcing pieces are mounted respectively in the slots. The upper has bottom edge. The welt is attached to the bottom edge of the upper. Nails are driven into the shoe sole through the welt and the reinforcing pieces in the slots to attach the upper to the shoe sole. The reinforcing pieces provide a resilient pliable medium to hold the nails so the shoes in accordance with prevent invention can be used for longer time.

  • Publication number: 20020093162
    Abstract: A foldable scooter step board includes a board body and a pair of supporting walls. The board body has a predetermined size for supporting a user standing thereon, wherein a wheel chamber is integrally provided at a tail portion of the board body for rotatably mounting a rear wheel. The pair of supporting walls are integrally protruded underneath the board body for rigidly supporting the board body. Therefore, the board body with the supporting walls is integrally formed in one piece such that the step board is capable of more evenly distributing and supporting a downward force and stress applied by the user's weight.
