Abstract
The present invention pertains to a sulky for horse-drawn harness racing including a frame, a seat, and a pair of wheels. The frame comprises an arch, a fork assembly secured to each end of the arch, a pair of spaced-apart rails extending forwardly from the arch in a direction of travel, and a stirrup secured to each rail. Each fork assembly comprises a pair of spaced-apart legs and an axle. Each wheel is positioned between a respective pair of legs and rotatably secured to the axle. The frame may also include a support strut extending between a respective fork assembly and rail to provide additional strength to the frame.

A sulky comprising:
- (a) a frame including an arch, a fork assembly secured to each end of the arch, a wheel rotatably secured to each fork assembly, a pair of spaced-apart rails extending forwardly from the arch in a direction of travel, a seat secured to the arch, and a stirrup secured to each rail;
- (b) wherein the arch comprises a hollow elongated beam having a noncircular cross-section defined by a major inner axis x and a minor inner axis y, the arch including a tubular reinforcement member disposed within the hollow elongated beam, the member having an outer diameter which is the same or less than the minor inner axis y of the beam and dimensioned to fit securely within the beam.
A sulky comprising:
- (a) a frame including an arch, a fork assembly secured to each end of the arch, a wheel rotatably secured to each fork assembly, a pair of spaced-apart rails extending forwardly from the arch in a direction of travel, a position along the arch which is equidistant from each rail being defined as α, a seat secured to the arch, and a stirrup secured to each rail;
- (b) wherein a midpoint β is defined along the length of the arch, and both the seat and α are offset more than 15.25 centimeters in a same direction from the midpoint β.
(canceled)
A sulky comprising:
- (a) an arch including a hollow elongated beam;
- (b) a fork assembly secured to each end of the arch and including a pair of opposed legs, the legs in each pair of opposed legs being distanced about four inches or less from each other;
- (c) a wheel positioned between each respective pair of legs and rotatably secured to each fork assembly;
- (d) a pair of spaced-apart rails extending forwardly from the arch in a direction of travel;
