  • Patent number: 5657857
    Abstract: A pivotal idler frame assembly for conveyors is disclosed in one preferred embodiment of the present invention as including an idler frame assembly selectively disposed in a pivotal relationship to a stationary conveyor frame. The idler frame assembly consists of a hinge member rotatably engaging at least two fixation members of the idler frame assembly and at least two support flanges of the conveyor frame which are correspondingly disposed in alignment with the fixation members. By releasing the operable engagement of a stabilizer member, the idler frame assembly may be pivoted in relation to the conveyor frame to remove the rollers of the idler frame from communication with a moving member. In addition, the structural hinge member provides means for slideably removing the idler frame assembly from beneath the moving member and adjacent the conveyor frame to expose the rollers of the idler frame assembly for dismounting and mounting.
