Device for maintaining a moving curved surface a constant distance from a stationary point

摘要

A device for maintaining a moveable faceplate panel a constant distance from a stationary point includes a fixed caddy. The caddy has longitudinally parallel fixed rails which curve in the same direction as one curvature of the panel. A moveable caddy rides on the fixed rails and includes additional rails which curve in the same direction as the other curvature of the panel. A panel carrier rides on the additional rails whereby the surface of the panel remains the constant distance from the stationary point and as movement occurs along either or both sets of rails.
