Track and trolley system for movable wall panels

A track and trolley system for movable wall panels comprising:

• a track having upper and lower flanges, said upper and lower flanges being horizontally and vertically displaced from each other and defining a channel, said upper and lower flanges each having a disc-supporting surface;
• a carrier shaft disposed between said flanges and adapted to engage the wall panel;
• and
• a trolley having upper and lower discs rotationally mounted on said shaft, said upper and lower discs each having a lower surface supported on said disc-supporting surfaces of said upper and lower flanges, respectively, and each of said upper and lower discs including an outer edge and a center, each of said lower surfaces sloping from said outer edge toward said center such that each of said lower surfaces is concave.

A track and trolley system for movable wall panels comprising:

• a track having upper and lower flanges, said upper and lower flanges being horizontally and vertically displaced from each other and defining a channel, said upper flange having a first disc-supporting surface including inner, middle and outer cylindrically contoured regions, each of said regions having a different curvature, said lower flange having a second disc-supporting surface;
• a carrier shaft disposed between said flanges and adapted to engage a wall panel;
• and
• a trolley having upper and lower discs rotationally mounted on said shaft, said upper disc having a first lower surface supported on said first disc-supporting surface of said upper flange, and said lower disc having a second lower surface supported on said second disc-supporting surface of said lower flange.
