Abstract

A motorized golf bag cart includes a base frame which extends and retracts telescopically to respectively expand or collapse a battery storage compartment. A drive motor supported in the base frame is linked to a drive axle which selectively drives a pair of drive wheel hubs positioned on respective opposite sides of the base frame. The base frame also includes a pair of transversely extending hollow tube which receive respective first and second telescoping support axles such that they are movable between an extended, operative position and a retracted, compact storage position. An articulating handle is designed to be compactly folded. The inventive golf bag cart is thus quickly and easily changeable between an extremely compact storage and transport configuration and a very stable, four wheeled, operative position.

Dependent claims

A motorized golf bag cart, comprising:

a. a handle;
b. a base frame attached to said handle, said base frame comprising:
i. a first tube with a longitudinal axis extending substantially in a direction of travel of said cart;
and
ii. a second tube with a longitudinal axis extending substantially in the direction of travel of said cart, said second tube being telescopically received within said first tube such that said second tube can be selectively extended and retracted relative to said first tube between respective base frame operative and storage positions, said base frame including a battery storage area for supporting a storage battery when in said extended, base frame operative position which battery storage area collapses when said base frame is in said retracted, storage position;
c. a motor supported on said base frame;
d. a pair of support wheels attached to respective support axles which are, in turn, attachable to said base frame;
e. a pair of drive wheels attached to respective opposite ends of a drive power axle which is, in turn, attached to said base frame;
f. a transmission which transmits power from said motor to said drive power axle;
and
g. said storage battery is removably supported on said base frame such that it is connectable to provide a source of electrical energy to said motor.

b. a handle;
c. a base frame attached to said handle, said base frame comprising:
i. a pair of transverse hollow tubes, each of which extends in a direction substantially transverse to a direction of travel of said cart, each of said transverse hollow tubes having an open end which telescopically accommodates a respective one of said pair of support axles such that each support axle can be selectively extended and retracted between respective operative and storage positions;
d. a motor supported on said base frame;
e. a pair of drive wheels attached to respective opposite ends of a drive power axle which is, in turn, attached to said base frame;
f. a transmission which transmits power from said motor to said drive power axle;
and
g. a storage battery removably supported on said base frame such that it is connectable to provide a source of electrical energy to said motor.

ii. a first tube with a longitudinal axis extending substantially in a direction of travel of said cart;
and
iii. a second tube with a longitudinal axis extending substantially in the direction of travel of said cart, said second tube being telescopically received within said first tube such that said second tube can be selectively extended and retracted relative to said first tube between respective base frame operative and storage positions;
d. a motor supported on said base frame;
e. a pair of drive wheels attached to respective opposite ends of a drive power axle which is, in turn, attached to said base frame;
f. a transmission which transmits power from said motor to said drive power axle;
and
g. a storage battery removably supported on said base frame such that it is connectable to provide a source of electrical energy to said motor, said battery being supported in a battery storage area formed in said base frame when said base frame first and second tubes are telescopically extended to said base frame operative position, said battery storage area collapsing when said base frame first and second tubes are in said retracted, storage position.
