Abstract
Various technologies for reducing or increasing a speed of a personal transportation vehicle by rotating its handlebar. Some technologies provide this functionality based on a stem, a rack, and a brake. Some technologies provide this functionality based on a worm gear, a stem, and a brake. Some technologies provide this functionality based on a cam, a cam follower, a rod, a stem, and a brake.
Claims3
A device comprising:
- a handlebar having a longitudinal axis;
- a circular gear radially extending from the handlebar;
- a stem engaging the handlebar such that the handle bar rotates about the longitudinal axis relative to the stem;
- a rack extending between the circular gear and the stem, wherein the rack meshes with the circular gear;
- and
- a brake operationally coupled to the movable rack, wherein the brake is configured to be actuated based on the circular gear rotating via the handle bar and causing the rack to move.
