Abstract
A telescopically collapsible hand-pulled golf cart comprises a first tubular elongated member which includes bag supports and a pair of parallelogram linkages pivotally mounted at their upper ends to the first member and including wheels at their lower ends. A second elongated member is telescopically slidable in the first member and can be locked thereto. A third elongated member located inside the first member is slidable within the second member. A "Y"-connector is fixedly mounted as the lower end of the third member and has arms which protrude through a slot longitudinally defined on the rear part of the first member. A pair of links join the parallelogram linkages to the arms of the "Y"-connector. The third member is slidable a limited distance within the second member to provide a lost-motion movement to the latter. This allows an adjustment of the second member relative to the first member with no effect on the positions of the wheels. At the two extreme positions of the third member relative to the second member, a further displacement of the second member produces a linear movement of the "Y"-connector along the slot which thus causes by way of the links and the parallelog…
