51692201, Dec 8, 1992

Filed:

Dec 10, 1991

Appl. No.:

7/804421

Inventors:

Martin R. Herr - New Holland PA
David L. Herr - Ephrata PA

International Classification:

A47F 310

US Classification:

312305

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.

Abstract:

The apparatus is an apparatus for rotating a "lazy susan" shelf inside a cabinet. The apparatus uses a cam action to move the door back toward the axis and away 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 shelf 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 support on the rotating shelf assembly which carries a roller that follows a stationary circular 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.
