BICYCLE TUBELESS RUBBER TIRE DEVICE, AND BICYCLE EQUIPPED THEREWITH

摘要

PPROBLEM TO BE SOLVED: To improve the low vibration absorbing capacity peculiar to a puncture-proof tubeless tire, and to change a worn tire anywhere by using a simple tool without detaching a wheel from an axle. PSOLUTION: Tire-attached fins 4 which extend outwardly in the radial direction and surround the entire circumference of a wheel rim with tire-mounting through holes 4a arranged in the circumferential direction at equal intervals arranged in the predetermined positions in the radial direction are formed substantially at a center of an outer circumferential surface of a rim 1. A tire 3 has no tire cavity or rubber tube, but has a substantially T-shaped section consisting of a leg part 3A extending in the radial direction and a ground contact part 3B spreading in the right-to-left direction at a tip thereof. A rubber-made spring case 6 to store a coil spring ring 5 bent in a doughnut shape in a vertical posture is abutted on a back side 3b of the ground contact part 3B. The tire 3 is secured to the wheel rim 1 via a spring stop plug 11. PCOPYRIGHT: (C)2005,JPO&NCIPI
