Abstract
The present invention relates to a runflat device (2), particularly, but not exclusively, a combined runflat and double sided beadlock that can be fitted to any size and type of wheel (1) regardless of the shape and depth of the wheel well (10). The runflat device (2) can be fitted using standard tools and tightened through manipulation of a valve assembly (52).
Claims48
A runflat device arranged to be disposed on a wheel inside a tire, the runflat device comprising a body having a length which, in use, extends around the circumference of a wheel and further comprising a valve assembly and a retraction mechanism connected to the valve assembly, wherein the valve assembly is movable to tighten the runflat device onto the wheel by means of the retraction mechanism.
A runflat device comprising a number of discrete segments connectable together to form a chain which, in use, runs around the circumference of a wheel.
(canceled)
A wheel and runflat device combination, the wheel having a pair of rims with an area therebetween, and the runflat device being located such that it rests on parts of the wheel adjacent the rims and spans said area.
39-44. (canceled)
A method of fitting a runflat device to a wheel, comprising the steps of:
- inserting the runflat into a tire cavity;
- fitting a first bead of the tire to the wheel rim;
- connecting two ends of the runflat device together;
- retrieving a valve, which forms part of the runflat device, from the tire cavity;
- fitting a second bead of the tire to the wheel;
- pulling the valve through a valve hole in the wheel;
- and manipulating the valve to tighten the runflat device to a predetermined degree.
