Abstract
A track mounting system for supporting equipment, such as a dental light, includes a pan-shaped carriage which is suspended from the track mounting system and to which the light or other equipment is attached. The track mounting system includes a pair of spaced, parallel tracks which are engaged by rollers rotatably mounted on inner walls of the carriage. At least one of the rollers is formed from a relatively hard material and is concave to mate with the complementary surface on one of the tracks to provide resistance against side loads. Other rollers are formed from a relatively soft material and are convex to provide a light frictional resistance to movement of the carriage along the tracks that inhibits drift, over-travel and other inadvertent movement of the carriage, while reducing noise.
