TRACK-SUPPORTED PLAYGROUND SHUTTLE

摘要

A playground shuttle device includes a track having an upper surface and a lower surface and a support structure connected to and supporting the track. The shuttle device includes a shuttle having a housing defining a chamber through wh ich the track traverses and a transport assembly carried by the housing. The transpo rt assembly includes a plurality of wheels rotatably mounted thereto and positioned so as to ride along the upper surface of the track. The transport assembly includes a brake assembly operably connected thereto by a biasing element. The brake assembly includes at least one brake element that is engagable with the track. The brake assembly is movable relative to the transport assembly between a brake position wherein the brake element engages the track and a free-roll position wherein the brake element is disengaged from the track. When a force is applied to the brake assem bly against the biasing element, the brake elements are disengaged from the track to move the shuttle to the free-roll position. Removal of the force from the brake assem bly engages the brake element with the track to move the shuttle to the brake positi on.
