An internally illuminated snowboard track for recreational areas or parks which are operated at night is made up of a continuous elongated transparent rail which is supported a predetermined distance above the ground by a base support member, and a light source extends longitudinally and internally of the rail to project light outwardly therefrom. A base stabilizer beneath the support member can either be planted in the snow or anchored to the ground surface in the track system may be inclined, curved, straight or provided with one or more bends. A snowboard ramp may be constructed in the same basic manner to serve as a jump for snowboarders.

Why it's free to use
- Filed November 5, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 5, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 5, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
