Abstract
A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.
Claims11
A tricycle, comprising:
- a frame;
- a pair of rear wheels configured for rotatable connection to one side of the frame;
- a handlebar configured for mounting on another side of the frame;
- a fork configured for connection to the handlebar to enable force exerted on the handlebar to turn the fork;
- a front wheel configured for rotatable connection to the fork;
- a pedal rod configured to extend through the front wheel for supporting pedals to enable a rider to rotate the front wheel;
- a spring interposed between the pedal rod and a connection on the fork for maintaining a portion of the fork at a variable spaced-apart distance from the pedal rod and for enabling a distance between the pedal rod and the portion of the fork to vary as the rider pedals the front wheel;
- and
- a housing covering at least a portion of the spring and extending toward the pedal rod, wherein the housing includes a slot therein through which the pedal rod is configured to pass, the slot being sized so that as the distance between the pedal rod and the portion of the fork varies, the rod is enabled to move up and down within the slot.
