The present invention provides a restraining system for an axle mounted wheel of a vehicle, the vehicle having a frame to which the axle is secured, leaving sufficient clearance to avoid road hazards and not interfere with the wheels motion during normal operation of the vehicle. The system comprises a cage assembly secured to the frame in the vicinity of the vehicle so as to leave a lower part of the wheel exposed allowing the wheel to, contact the road and to retain the wheel in close proximity to its original installation point and entrap the wheel and carry it along with the vehicle should it become detached from the axle.

Why it's free to use
- Filed June 27, 1997 and granted March 23, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
