Abstract

The present invention is a roll of puncture resistant lining, with one of its sides having a sticky surface for adhering to the inside of the rim, with a plurality of buttons precut into the roll. The roll of puncture resistant lining is fabricated from such materials as cloth, rubber, or plastic. The buttons are removed from the bulk of the roll and are adhered over each spoke end on the inside of the bicycle tire's rim. The cyclist is now afforded a more puncture resistant tire and a longer lasting inner tube.

Rim liner of puncture resistant buttons for bicycle tires

Flat tires have long plagued bicyclists, from the professional to the amateur. Advances made include layering the outer wall of the tire with a puncture resistant lining to protect the vulnerable inner tube. However, what inventors have failed to realize is that the vast majority of flat tires result from punctures caused by the ends of spokes on the inside of the rim. The threat of a puncture resulting from the sharp metal spoke ends is ever-present. Any time a little extra force is applied to the wheel from such mishaps as hitting a pothole or curb, or simply by landing hard after a jump, the inner tube is in jeopardy. In addition, these punctures can be caused simply by riding with the same inner tube too long, as the steel spoke ends gradually wear away the inner tube wherever the two come into contact.

The present invention is a roll of puncture resistant lining, with one of its sides having a sticky surface for adhering to the inside of the rim, with a plurality of buttons precut into the roll. The roll of puncture resistant lining is fabricated from such materials as cloth, rubber, or plastic. The buttons are removed from the bulk of the roll and are adhered over each spoke end on the inside of the bicycle tire's rim. The cyclist is now afforded a more puncture resistant tire and a longer lasting inner tube.

Figure 1 Perspective view of inside of bicycle tire rim

Figure 1 shows a perspective view of the inside of a bicycle tire rim 110 and includes a plurality of spoke ends 120. The spokes extend from the hub of the wheel and are screwed into the spoke ends 120. Spoke ends 120 are metal and have sharp edges that come into contact with the inner tube and often are the cause of punctures.

Figure 2 Roll of protective lining rim tape 200

Figure 2 shows a protective roll of tape 210 and contains a plurality of pre-cut tube-saver buttons 220.

In operation, the protective roll of tape 210 is unwound and pre-cut tube-saver buttons are applied over each spoke-end 120, sticky side down. The vulnerable inner tube is now protected from punctures caused by the sharp spoke-ends 120.
