Abstract:
1. A caster wheel system comprising: an axle assembly for operationally coupling said caster wheel system to a vehicle; a wheel fork assembly including a wheel fork member and a wheel, rotatably coupled to said wheel fork member; and a pivot block assembly, said pivot block assembly providing a coupling interface between said axle assembly and said wheel fork assembly, said pivot block assembly being pivotally coupleable to said wheel fork assembly and rotatably coupleable to said axle assembly, whereby said wheel fork member may pivot around an axis defined by a first elongate member adapted for operationally coupling to the vehicle, said first elongate member having a first circumference; said first elongate member having an longitudinal aperature extending along a longitudinal axis of said first elongate member; a second elongate member having a second circumference, said second circumference being less than said first circumference, a first end of said second elongate member being positionable within said longitudinal aperture of said first elongate member, said second elongate member having a second end, at least said second end of said second elongate member having a threaded circular cross-section; a coupling means for coupling said second elongate member to said first elongate member when said first end of said second elongate member is positioned within said longitudinal aperture of said first elongate member; and a top bearing positionable over said second elongate member and having a top surface abutting an end of said first elongate member, a bottom surface of said top bearing abutting said pivot block assembly, said top bearing reducing a resistance in rotating the pivot block assembly with respect to the axle assembly; and
