ABSTRACT:
High performance, light-weight skate wheels are produced with special permeable cores and without air bubbles for in-line roller skates to attain greater strength, speed, maneuverability and control. In order to facilitate rotation, one or more bearings are seated in the hub of the gas permeable core. The gas permeable core which is preferably made of high-impact plastic can be reinforced with fibers. The gas permeable core can also comprise complementary core sections and can have an array of spokes which connect a hub and an inner rim. In the preferred form, the gas permeable core has an outer portion providing a hollow shell upon which a high performance non-pneumatic tire is secured. In order to prevent air bubbles from forming in the solidified core during molding, the core is formed with gas passageways, such as vent holes, openings, tunnels, air channels, micropores or apertures. Preferably, the micropores or apertures are formed in the tire-engaging surface of the gas permeable core. The core can also have spikes, deflectors or indentations to minimize gas deflection and turbulence during molding in order to produce a more homogeneous core. Interlocking fingers or hollow pins and sockets can also be used to securely connect complementary core sections.
