ABSTRACT:
Rotating "lazy susan" shelf hardware for the interior of a cabinet. The apparatus uses a cam action to move the door back toward the axis and way from the cabinet edges as rotation begins upon opening, at the same time releasing a detent on the rotational motion of the shelves. As the rotation position approaches the closure position of the door, the door moves gently out toward its closed position, and the door is automatically aligned. This is accomplished with a spring loaded arm on the rotating shelf assembly which carries a roller that follows a stationary circualr cam that has an indentation in it to activate the door's front to back movement. The forward motion of the door caused by the spring action is also slowed by a movement damper.
