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 parallelogram linkages the wheels to extend or retract relative to the first member from an operational to a storage position or vice versa.
A golf cart including an elongated tubular first member, an elongated tubular second member telescopically slidable in said first member, grip means on said second member, bag supporting means fixedly mounted to said first member, locking means to secure said second member at a desired position relative to said first member, at least a "V"-shaped bracket fixedly mounted to said first member, said "V"-shaped bracket having two arms extending divergingly from one another and rearwardly from said first member, a pair of parallelogram linkages each pivotally mounted at an upper end thereof to a corresponding arm of said "V"-shaped bracket, wherein said parallelogram linkages are adapted to pivot in the respective planes of the arms of the "V"-shaped bracket;
A golf cart including an elongated tubular first member, an elongated second tubular member telescopically slidable in said first member, grip means on said second member, bag supporting means fixedly mounted to said first member, locking means to secure said second member at a desired position relative to said first member, a pair of wheel assemblies pivotally mounted to said first member for spreading and collapsing movement relative to said first member, link means pivotally joining said wheel assemblies to a connector means protruding through said first member in a slot longitudinally defined therein, a third elongated member being provided in said first member and sliding within said second member, said third elongated member having abutment means for limiting telescopic movement of said third member relative to said second member, said third member being mounted at a lower end thereof to said connector means, said third member providing a lost-motion movement allowing the second member to be extended and retracted relative to the first member a limited distance without causing the wheel assemblies to extend or collapse, said second and third members co-acting at the limits of said limited distance for causing the wheel assemblies to spread outwardly when the second member is drawn out from the first member and to retract when the second member is inserted into the first member.
