  • Patent number: 4887835
    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.
