Abstract

A collapsible tricycle for the use of young children has a front wheel, two rear wheels, a saddle, and a frame, to which the saddle is pivoted. The frame includes a front part, a stationary part secured to the front part, a rear part, and a connecting rod. The stationary part has two parallel walls at the rear portion; the front end of the saddle is pivotally connected to upper portions of the walls; the front portion of rear frame part is pivotally connected to the lower portions of the walls. The rear frame part has two parallel walls defining a space wider than the stationary part such that the stationary part can be partially received in the space when the tricycle is folded, allowing the folded tricycle to be relatively compact. The middle of the saddle is pivoted to the rear frame part. And, the connecting rod is pivoted to both the stationary part and the rear frame from two ends for preventing both from moving relative to each other when the tricycle is ridden. The bottom of the rear part of the saddle is stably supported on the rear frame when the tricycle is stretched. In addition, an engaging rod of the saddle is biased forwards to engage engaging gaps of the rear frame by a spring for preventing the tricycle from being accidentally folded; a pull handle is connected to the engaging rod for a user to pull to disengage the rod from the gaps.
