Abstract:
1. An idler frame assembly for a conveyor, the idler frame assembly comprising: a fixed frame assembly; a roller support assembly engageable with the fixed frame assembly, the roller support assembly being slidable relative to the fixed frame assembly between an operative configuration and a non-operative configuration; the roller support assembly comprising a roller support frame pivotable between a raised operative position and a lowered inoperative position; a guide device mounted on the fixed frame assembly so as to be fixed relative thereto, the guide device arranged so as to urge the pivotable roller support frame to move from the lowered inoperative position to the raised operative position when the roller support assembly is moved toward the operative configuration; an engaging portion disposed at an end of the fixed frame assembly adjacent the guide device, and the engaging portion and the roller support assembly being configured such that the engaging portion mates with the roller support assembly when the roller support assembly is in the operative configuration, and thereby constrains movement of the roller support assembly in a plane perpendicular to the direction of slidable movement of the roller support assembly; and a securing device disposed at an end of the fixed frame assembly remote from the guide device, the securing device constraining slidable movement of the roller support assembly and thereby securing the roller support assembly in the operative configuration.
