Abstract: A sulky for carrying a rider behind a horse consisting essentially of an arch, a pair of wheels connected to the arch, a pair of rails extending from the arch forward in the direction of the horse, one on each side thus establishing a plane and the direction of the rails establishing a longitudinal axis of the sulky, a coupling for coupling each of the rails to the arch, wherein the coupling permits lateral movement of the rails about vertical pivot axes relative to the arch and an element for stabilizing movement of the rails connected between the plane of the rails substantially adjacent the horse and the arch. In a preferred embodiment the motion of the rails is restricted to lateral movement in a horizontal plane and the ends of the rails adjacent the arch are movably connected with a "U" joint overlapping the upper and lower surfaces of the arch.

Abstract: A sulky for carrying a rider behind a horse, comprising an arch, a pair of wheels and a pair of substantially horizontal rails flexibly or movably coupled to the arch, the rails adapted to embrace the flanks of the horse and further comprising stabilization. In a particularly preferred embodiment, a pivot joint between the rail and the arch permits lateral motion of the rail, a shock absorber provides stabilization, and a fork assembly for each side of the sulky is incorporated which fork assembly is capable of telescoping axial motion. The sulky results in improved performance including tracking, efficiency and safety.
