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 sections 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. An inclined camming surface is provided within the cavity so that when the plug is moved by the release bar, the camming surface acts upon the first retaining pin to withdraw it for releasing the retaining engagement between the upper section and the middle section. The plug has a round-headed lower end projecting out of the upper section and into the middle section which when moved to contact the second retaining pin between the middle section and the lower section acts upon and moves it back to break the retaining engagement between the middle section and the lower section.
