Patent ID: 8282018

Claim:
A method of providing a smooth, low noise dolly movement comprising the steps of: providing first and second track sections, each section including first and second hollow rails; providing for each rail a respective support member including a hollow part and opposed flanges; continuously and eccentrically supporting each rail with the hollow part; spacing the support members apart with a plurality of cross members, each cross member having opposed ends and each end rotatably coupled between the opposed flanges of one of the rail support members; providing a male conical ferrule at one end of each rail and a female conical ferrule at the opposite end of each rail, rail ends at an end of the same track section having one male ferrule and one female ferrule; providing adjacent to each mated ferrule pair a buckle with a lever operated latch and a slotted latch plate affixed to the hollow part; mating the male and female ferrules at one end of the first track section with the female and male ferrules at one end of the second track section; drawing the mated ferrules together by hooking the latch in the slotted latch plate and rotating the lever to close the buckle; limiting dolly bumps by matching a rail outer diameter with a ferrule outer diameter where the rail abuts the ferrule; and, limiting dolly noise by selecting a rail material and a mating dolly wheel material that produce a lubricious wear byproduct during use.
