| Abstract: |
A self propelled golf bag cart assembly (10) is provided to allow a golfer to walk during a round of golf while having the golf cart (12) and the contents carried by the cart (10). The bag cart (10) includes a plurality of cooperative subassemblies for performing specific functions. The bag cart (10) includes a frame subassembly (16), a first drive wheel subassembly (18), a second drive wheel subassembly (20), a caster subassembly (28), a handle subassembly (30), and a hand grip subassembly (32). Each of the drive wheel subassemblies (18, 20) includes a shoulder (22), a motor (26), and a wheel (24) subassembly. Power and control is provided by directly driving a motor (118) associated with each wheel (24) through an electrical subassembly (38). The electrical subassembly includes a battery (48) and a variety of controlling components situated in a manual control box (34), a main power unit (54) the hand grip (32), and an optional remote control unit (36). The bag cart (10) is primarily characterized by direct independent drive of the wheels, compactiblity from a use mode to a storage mode, and precise user control from the hand grip (32), or the remote control unit (36). The primary expected usage of the self propelled golf bag cart assembly (10) is by individual golfers on walking courses.

I claim:
1. A self propelled golf bag cart assembly, comprising:
- a carrying frame subassembly for supporting a golf bag in an orientation in which the contents thereof are accessible to a user;
- a first drive wheel subassembly and a second drive wheel subassembly, opposingly mounted to the frame subassembly by associated shoulder subassemblies in such a manner that the drive wheel subassemblies in such a manner that the drive wheel subassemblies may be oriented in at least a use mode and a storage mode, said use mode being characterized as providing stable rolling support to the cart assembly, and said storage mode being characterized by being more compact than said use mode;
- a caster subassembly mounted on the frame subassembly in a position so as to provide, with the first and second drive wheel so as to provide, with the first and second drive wheel subassemblies, tricycular rolling support for the bag cart assembly;
- a handle subassembly mounted on the frame subassembly at a position opposite the caster subassembly; and
- user controllable electrical means for causing the drive wheel subassemblies to propel the cart assembly at speeds and in directions selected by the user;
- 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 further characterized by the first and second drive wheel subassemblies being commonly rotated on said shoulder subassemblies in a direction parallel to said longitudinal vertical plane so as to be separated longitudinally from the bottom portion of the frame subassembly, each of the wheel subassemblies being opposingly pivoted on said shoulder subassemblies in a direction perpendicular to said longitudinal vertical plane so as to be displaced outward from said bottom portion, said caster subassembly 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 the wheel subassemblies, and the handle subassembly being pivoted outward from the frame subassembly within said longitudinal vertical plane; and
- said storage mode is characterized by the wheel subassemblies being rotated on said shoulder subassemblies so as to be aligned directly against the opposing sides of the frame subassembly, the caster subassembly is pivoted so as to be situated between the wheel subassemblies, and the handle subassembly is pivoted so as to lie longitudinally between the wheel subassemblies, but displaced above the wheel subassemblies, while not projecting longitudinally beyond the extent of the frame subassembly.
