A chute system for conveying articles, preferably documents, from an upper to a lower elevation in a building. The system includes a vertical post, an outer wall that is concentric therewith, and a helical chute wound around the post. The chute is secured at an inner edge to the post and at an outer edge to the wall. The chute comprises a plurality of chute segments secured together in stepped relationship to each other. Each chute segment has a triangular upper wall disposed at a first angle to the post and sloping downwardly toward the outer wall. The upper wall is simultaneously disposed at a second angle to the horizontal and slopes generally downwardly toward a lower end of the post. Each chute segment further includes a first flange extending upwardly from the upper wall and a second flange extending downwardly from the upper wall. Adjacent chute segments are secured together by welding the second flange of a first chute segment to the first flange of a second chute segment.

A transition frame and a chute system incorporating the same. The frame includes two first chain connectors and three second chain connectors which are positioned in different configurations on the frame. The frame defines a central opening through which at least a portion of a chute section is receivable. The first and second chain connectors allow chains to be attached to the transition frame to connect the chute to a support system or to connect different types of chute sections together. If the chute is formed from a plurality of molded sections and rolled sections, the frame can be oriented in such a manner so as to allow at least two chains to extend between the frame and the molded sections and at least three chains to extend between the frame and the rolled sections. The frame can be inverted as required to allow the molded sections to be positioned above or below the rolled sections. The frame can also be utilized to connect support chains between a support system and a column of rolled sections only or molded sections only.

A door assembly for a chute system comprising a door pivotally connected to a frame assembly mountable around an opening in a chute system. The door is manufactured from stainless steel and is free of welds. The door includes an automatic closer mounted to its interior surface and being directly connected to the frame assembly at one end and to the door at the other end. When the door is opened, the closer moves with the door out of the opening to the chute system, thereby increasing the usable space for inserting articles into the chute. The closer does not intrude into the interior of the chute when the door is in a closed position. The door may also include a deflector plate mounted proximate the door hinge to protect the hinge and prevent debris from articles inserted into the chute from dropping into the gap between the door and frame and interfering with the action of the hinge.
