  • Patent number: 4061360
    Abstract: A collapsible cart for carrying one or more golf bags while playing golf including a pair of large diameter wheels having an inflated pneumatic tire on each wheel and a foldable, lightweight, rigid frame of unique construction for positioning in a compact condition with folding of the frame between collapsed and extended positions enabling attachment and detachment of the independent wheels. The cart includes a unique U-shaped handle to facilitate movement of the cart by either pushing the cart or pulling the cart in the nature of a rickshaw. The handle is also pivotal for movement to a compact position alongside the frame. A pivotal bar is mounted on the frame to support the bottom portion of one or two golf bags and a tie cord is provided on the upper portion of the frame to retain the upper end portion of the bag or bags on the frame. Detachment of the frame from the wheels enables storage of the cart in relatively small spaces.
