Abstract: A collapsible luggage trolley includes a wheeled base from which two parallel posts extend upward with a handhold mounted on the free ends thereof and a middle support member connected between the posts at a middle position thereof. Each of the posts has a lower, a middle and an upper tubular section telescopically received within each other and retained in the expanded position by the first and second retaining pins which are biased to extend through holes formed on the tubular sections. A plug movably received within the upper section is connected to a release bar disposed within the handhold by a link to allow the plug to be controlled by the release bar. A cavity is formed inside the plug for receiving therein the first retaining pin between the upper section and the middle section.
