Self propelled golf bag cart

A golf bag cart assembly for powered transport of a loaded golf bag, comprising;

• a folding frame structure which may be expanded to a use mode for use and compacted to a storage mode for storage and transport, the folding frame structure including a central frame for providing support to the side of a golf bag, a caster structure including a caster member pivotally mounted on said central frame and a caster wheel pivotally attached thereto, said caster structure providing bottom support for the golf bag, and a handle structure pivotally mounted upon said central frame, said handle structure including a hand grip member for grasping by a user;
• a pair of opposing drive wheel structures mounted upon said central frame by shoulder structures permitting controlled rotation in at least two dimensions, each said pair of drive wheel structures including opposing wheel means and providing with said caster structure, tricycular rolling support for the cart assembly, and independently controlled motor means for providing rotational force to said opposing wheel means;
• electrical power storage and delivery means;
• and
• electrical controls mounted on the folding frame structure so as to be readily accessible to the user, the electrical controls including power activation control means, speed control means and directional control means, each of the electrical controls affecting the operation of said motor means;
• wherein the cart assembly is generally symmetrical about a longitudinal vertical plane, both in said use mode and said storage mode;
• said use mode is characterized by said wheel means being commonly rotated on said shoulder structures in a direction parallel to said longitudinal vertical plane so as to be separated longitudinally from the bottom portion of the folding frame structure, each of said wheel means being opposingly rotated on said shoulder structures in a direction perpendicular to said longitudinal vertical plane so as to displaced outward from said bottom portion, said caster structure being rotated in a direction parallel to said longitudinal vertical plane so as to be displaced from said bottom portion in a direction opposite to the direction of longitudinal displacement of said wheel means, and said handle structure being pivoted outward from the central frame within said longitudinal vertical plane;
• and
• said storage mode is characterized by said wheel means being rotated on said shoulder structure so as to be aligned directly against the opposing sides of the folding frame structure, said caster structure is pivoted so as to be situated between said wheel means, and said handle structure is pivoted so as to lie longitudinally between said wheel means, but displaced above said wheel means, while not projecting longitudinally beyond the extent of the folding frame structure.
