International Classification:

D1202

US Classification:

D12 23

US Patent:

42893240, Sep 15, 1981

Filed:

Oct 4, 1979

Appl. No.:

6/081977

Inventors:

Edwin A. Nemeth - Martinez CA

International Classification:

B62B 302

US Classification:

280 38

Abstract:

A golf bag carrying golf cart is disclosed which is easily stored in a collapsed compact position. A tricycle steering wheel is mounted on an arm which fits telescopically on an upwardly arching segment of a main column. The arching segment is secured by a pin to the main column in either a down position wherein the wheel is extended to a steering position or in an up position wherein the wheel is in a compact upwardly and inwardly projecting position such that the wheel is suspended by its own weight in a position approximately conforming to the upwardly arching segment of the main column.

International Classification:

B62D 5104

US Classification:

180 65E

Abstract:

A power-assisted manually operated golf bag carrying cart is disclosed. The cart features a foldable tricycle support frame having parallel drive wheels, which can be maintained in parallel over a range of adjustment, and independently-powered direct drive d. c. motors coupled to shock isolated wheels. A control scheme is described wherein a hand grip with a mechanically isolated continuously variable throttle provides control signals to a power-control circuit providing independent direct drive to each of the drive wheels. Power supplied by variable pulse width pulse train developing intermittent high peak torque yet low average torque in the normal duty cycle range drives the d. c. motors. The motor drive scheme provides an electrical limited slip differential which permits easy turning without undesirable power dissipation.

International Classification:

H01M 212

US Classification:

429 84

Abstract:

Means for inhibiting the escape of liquid from a liquid electrolyte battery having at least one fluid vent, wherein the battery is subject to frequent partial rotation about a horizontal axis, such as in the mounting of a power-assisted manually operated golf-bag carrying tricycle cart. The apparatus comprises a manifold and a hollow tube defining a coil substantially in a plane perpendicular to the axis of contemplated battery rotation, the coil having an outlet suspended normally directly downwardly.
