Abstract

The collapsible wheeled frame comprises at least a front strut, a pair of rear struts and a lockable swivel base. The lockable swivel base is pivotally connected with the front strut and the rear strut, including a spring-loaded abutting slider for fixing the front strut and the rear strut in a using position. The release mechanism is manipulated by rotating a pair of push arms, when the push arms is rotated upwardly to a upright position, the spring-loaded positioning member is disengaged to permit the foldable upper frame changing its direction, and when the push arms is rotated downwardly, the spring-loaded abutting slider is refracted to permit the front strut and the rear strut rotating relative to each other.
