Plug for a tubeless bicycle wheel

摘要

A bicycle wheel is disclosed having a spoke, a nipple coupled to the spoke, and a rim coupled to the nipple and having an annular panel with inner and outer surfaces and an access hole. A plug is positioned over the access hole and includes a cap that is larger than the access hole, a leg extending from the cap and through the access hole, and a barb protruding radially from the leg to at least partially engage the inner surface of the annular panel. The plug can further include a resilient member compressed between the cap and the outer surface of the annular panel. On some rims, the annular panel has a non-planar contour. For these rims, the resilient member and/or the cap can be shaped to match the non-planar contour of the annular panel.

1. A bicycle wheel comprising:
a hub; a rim coupled to the hub and having an annular panel with inner and outer surfaces, the annular panel including an access hole defining inner and outer edges corresponding with the inner and outer surfaces, the access hole having a hole area sized to facilitate passage of a nipple; and a plug positioned over the access hole, the plug including:
a cap having an upper surface and a lower surface, and a cap area larger than the hole area;a plurality of legs extending from the cap and through the access hole, the legs spaced apart from each other around the periphery of the cap such that gaps are defined between the legs; anda barb protruding radially from one or more of the legs to at least partially engage the inner edge of the annular panel,wherein each of the gaps extends from distal ends of adjacent legs toward the cap and terminates short of a plane defined by the lower surface; wherein the plug further includes a resilient member compressed between the cap and the outer surface of the annular panel; wherein the resilient member has an unstressed thickness, wherein the resilient member has a stressed thickness when compressed between the cap and the outer surface, and wherein the stressed thickness is 50 to 95 percent of the unstressed thickness; wherein each barb has a contact surface spaced from a lower surface of the cap by a distance, and wherein the distance corresponds to a thickness of the annular panel and the stressed thickness of the resilient member.
