Locking threadless bicycle headset

摘要

The set of bicycle headsets that are threadless and/or have pressed frame cups/races can be locked to prohibit the nominal rotation of the headset and bicycle handlebars about the bicycle's steer tube by this invention. This invention uses standard threadless headset components in addition to three newly invented components: The upper head tube race with spin-lock grooves, the external ring lock, and the headset spacer with spin-lock grooves. The locking configuration is achieved by mating male pins on the interior surface of the external ring lock with female spin-lock grooves that are on the exterior surfaces of the upper head tube race with spin-lock grooves and headset spacer with spin-lock grooves. There are a sets of spin-lock grooves that, when the male pins are mated accordingly, provide the locked and unlocked configurations of the headset.

主权项

1. A bicycle headset comprising; an upper head tube race with a continuous horizontal and vertical pattern cut into an exterior of the upper head tube race, forming spin-lock grooves; a headset spacer with spin-lock grooves that sits on top of the upper head tube race, and; an external ring lock that seals around the upper head tube race and headset spacer that has two internal radially-pointing male pins that are horizontally and vertically offset, allowing the pins to slide between the spin-lock grooves of the head tube race and headset spacer.
