Abstract

A three-wheeled golf pushcart that combines the usage and benefits of a conventional pushcart and golf bag into a single piece of equipment. The cart comprises a collapsible three wheeled configuration and push bar. These collapsible mechanisms enable the cart to be transformed into two positions: folded or extended. The cart is also equipped with a plurality of golf club slots strategically formed into a V-shaped. In addition to the caddy console and accessories tray, removable storage compartments are also added to the perimeter of the cart's body for additional storage room. In an extended position, the cart is designed to be used for walking similar to using a “pushcart and bag combination”. In a folded position, the cart is compact and designed to fit securely onto the back of a motorized cart for riding, similar to a conventional golf bag. This compact folded position also makes it ideal for handling and stowing.

Dependent claims

An all-in-one golf cart, comprising:

at least three wheels, each of said at least three wheels rotatable and supporting the golf cart above a ground surface;
said at least three wheels movable between a folded storage position and an extended walking position, said at least three wheels located at a lowermost portion of the golf cart when in said extended walking position;
a push bar assembly collapsible between a folded storage position and an extended walking position;
a first plurality of golf club slots in a perimeter set and a second plurality of golf club slots in an interior set;
an upper chassis, center chassis, and lower chassis in a V-shaped configuration;
said center chassis extending between said upper chassis and said lower chassis, said center chassis fixed to said upper chassis and said lower chassis;
said at least three wheels including at least two rear wheels;
each of said at least two rear wheels rotatably supported from said lower chassis through at least one trailing arm which pivots relative to said lower chassis between said folded storage position and said extended walking position;
said at least two rear wheels supporting a weight of the cart when loaded and when said at least two rear wheels are extended into said extended walking position;
said at least three wheels including a third wheel located centrally between said at least two rear wheels and forward of said at least two rear wheels, said third wheel rotatably attached to said lower chassis, said third wheel supporting weight of the cart not carried by said at least two rear wheels;
a brake coupled to at least one of said at least three wheels;
said at least three wheels oriented to remain parallel with each other in both folded storage positions and extended walking positions for said at least three wheels;
said at least three wheels being fully extendable to said walking position wherein in said walking position said at least three wheels have a triangular form shape with distance between each of said at least three wheels to provide a base for the golf cart when moving;
and
said at least two rear wheels located further from each other when in said extended walking position than a height of said center chassis, providing stability for the cart.
