Abstract

The present invention is an apparatus for a wear indicator system of an in-line skate wheel. The wheel includes a center hard plastic core hub, a first concentric portion (Resin B) of a color B, and finally a second concentric portion (Resin A) of color A. Resin A makes up the outermost portion of the wheel, thus undergoes wear first. As the portion A wears out portion B of color B, is exposed. When the outermost edge of the wheel displays only color B then the wheel has fully matured and should be replaced. The diameter of portion A and B should be determined based upon the resin hardness, the intended use and the shape of the wheel.

Method of Determining When An Inline Skate Wheel Needs To Be Replaced

The exercise and recreational equipment market is growing rapidly each year, specifically the in-line skate market. In-line skates offer an enjoyable alternative to traditional exercise. With the growth of the industry, consumers desire innovative advances in the in-line skate technology to benefit performance, easy of use and safety. An increasing supply of replacement and aftermarket products are available to consumers.

The in-line skate and in-line skate accessory manufacturer that can consistently offer innovative quality products is positioned to expand market share.

In-line skate wheel wear is dependent on such factors as: usage time, the amount of weight the wheels are bearing, the surface quality, etc. The wheel's wear can greatly affect the skate's performance and the safety of the user. The wear rate is relatively unpredictable, therefore a wear indication system would greatly aid in the users assessment of the wheels current state. What is needed is a way to indicate when an inline skate wheel needs to be replaced.

The present invention is an apparatus for a wear indicator system of an in-line skate wheel. The wheel includes a center hard plastic core hub, a first concentric portion (Resin B) of a color B, and finally a second concentric portion (Resin A) of color A. Resin A makes up the outermost portion of the wheel, thus undergoes wear first. As the portion A wears out portion B of color B, is exposed. When the outermost edge of the wheel displays only color B then the wheel has fully matured and should be replaced. The diameter of portion A and B should be determined based upon the resin hardness, the intended use and the shape of the wheel.
