Abstract: Embodiments of the present invention provide a novel solution for preventing pinch flats and installation flats incurred by an inner tube as a result of the wheel striking an object. Embodiments are directed to an inner tube protector that fits within a tire and provides mechanical protection to the inner tube against tire strikes. Embodiments may include an inner region adapted to support an inner tube installed around a rim of a wheel. Additionally, embodiments may include an outer region adapted for insertion within and against the rim lip of the rim which provide protection to the inner tube responsive to the wheel striking an object. As such, embodiments may be positioned between the rim and inner tube in a manner that dulls an edge of the rim lip and, thereby, provides protection to the inner tube when compressed against the otherwise sharp edges of the rim lip.

Abstract translation: 本发明的实施例提供了一种用于防止由于车轮撞击物体而导致的内管引起的夹紧平面和安装平面的新颖解决方案。 实施例涉及装配在轮胎内的内管保护器，并且为内胎提供机械保护以防止轮胎撞击。 实施例可以包括适于支撑围绕轮的边缘安装的内管的内部区域。 此外，实施例可以包括适于插入到边缘的边缘内并抵靠轮缘的边缘的外部区域，其响应于车轮撞击物体而向内管提供保护。 因此，实施例可以以使凹边缘缘钝化的方式定位在边缘和内管之间，从而当压靠边缘唇缘的其它锋利边缘时，为内管提供保护。
