Definitions

  • This invention is regarding the inlineskate wheels.
  • 'injection mold' the plastic hub, and then 'insert mold' with the first product (Plastic Hub) and hard polyurethane, applying hard polyurethane on the center of the tire and edges that contact the road surface to excel running speed at straight line.
  • 'insert mold' with the second product and softer polyurethane applying it on the lateral parts of the tire to prevent slipping by increasing the friction with the road surface during rounding and cornering.
  • this invention makes the Plastic Hub (2) by injection molding in the first place and perform insert molding with the first product (Plastic Hub) and hard polyurethane (3) on the center (302) of the tire and edges (301) that contact the road surface to excel running speed at straight line. After then we do insert molding with the second product and softer polyurethane (4) on the both sides (401) of the tire. On the center (302) and edge (301) of the tire, polyurethane which has different material characteristics and degree of hardness is molded together to prevent slipping by increasing the friction with the road surface during rounding and cornering.
  • this invention uses hard polyurethane (3) on the center of the tire and the edges contacting the road surface and use softer polyurethane (4) with higher friction with road surface on both sides of the tire to prevent slipping during rounding and cornering.
  • This invention enhances the functionality of the wheels and allows various color and design expression by using different materials with different degree of hardness on the center (302) and edges (301) and the both sides (401).

Abstract

Cette invention concerne un procédé de fabrication de roulettes de roller en ligne. Après fabrication du moyeu en plastique par moulage par injection, on moule le premier produit (moyeu en plastique) avec insertion de polyuréthane durci dans la partie centrale et sur le bord du boudin en contact avec la surface de roulement, ce qui permet d'atteindre des vitesses de déplacement remarquables en ligne droite. On introduit enfin un polyuréthane au centre et dans le bord du boudin dans le but de l'empêcher de patiner, ceci en augmentant les frottements avec la surface de roulement dans les virages larges ou serrés.
