Abstract
A collapsible hand trolley includes a frame having manual gripping handlest its upper end, and a support plate at its lower end. A pair of wheel carriers is also mounted on the lower end of the frame. The trolley can be folded to a storage condition by pivoting the wheel carriers about generally vertical axes, and pivoting the support plate about a generally horizontal axis. When the wheel carriers have been unfolded to an operative position, a connection rod pivotably mounted to the frame is pivoted about a generally horizontal axis to a securing position between the wheel carriers in order to pre vent the wheel carriers from moving to their folded positions.
