  • Composite ball-bouncing tyre
    Patent number: 8297326
    Abstract: The present invention relates to a composite ball-bouncing tire, comprising a subtire and an inner tube inside it, wherein the subtire includes a space between a ring-shaped base and its side walls, and the space includes a plurality of rails and fastening grooves that are arranged at intervals on its inner walls. A slope part that converges against the rolling-forward direction is established atop on both sides of the plurality of the rails, and at the bottom of the fastening grooves, there is a plurality of fixing grooves. One or more resilient balls are established in each rail and the inner tube includes a plurality of fixing parts on top of outer walls of a base component. When the subtire and inner tube rolls, the resilient balls will be pushed into the rails along the slope part and be pressed to bounce, thus producing supplementary force to drive the tire to move forward.
