Abstract

The present invention relates to an interlocking flight for forming a flexible platform of a conveyor which may be of the continuous, vertical type. The flight is provided with oppositely-disposed first and engaging surfaces and an elongate portion having an upper surface generally normal to the engaging surfaces for forming a portion of the top surface of the platform. The flight is also provided with a pair of flanged portions which extend from opposite ends of the elongate portion. The flanged portions have opposing inner surfaces disposed generally normal to the elongate portion upper surface and a pair of opposing pivot pins, each of which extends from an inner surface. Also disposed at opposite ends of the elongate portion are a pair of land portions configured for rotatably receiving a corresponding flanged portion from another flight and having an opening for receiving a corresponding pivot pin therefrom to effect an interlocking engagement therebetween. Rotation of the flight is provided in a first direction about the pivot pins of another flight interlocked therewith to thereby make the platform flexible in the first direction. However, rotation of the flight in a second direction opposite the first direction is delimited by the second engaging surface of the flight abuttingly engaging a corresponding first engaging surface of the flight interlocked therewith to thereby make the platform rigid for supporting a load when extended horizontally.
