Abstract

A screening assembly support frame includes a body member defining a longitudinal axis. The body member has a pair of parallel, spaced elongate support members with a spacer arrangement extending between the support members. An engaging formation, for engaging a screen panel of the screening assembly to be supported by the body member, is carried on each support member with the body member and the engaging formations being symmetrical about the longitudinal axis.

Claims (10)

1. A screening assembly support frame, comprising:

a pair of support members, wherein the support members are elongated members which are substantially parallel;

two or more struts, wherein the struts extend between the pair of support members thereby supporting and spacing the support members;

a clip integral with each of the support members and configured to engage complementary formations of a removable screen panel, wherein the clip is a profile located on a top outside surface of each support member and extends substantially the entire length of the support member; and

a plurality of locating formations integral with the bottom of each of the support members and configured to removeably engage and secure to a head of a pin of an underlying screen deck, wherein the entire support frame is one piece of moulded material.

2. The screening assembly of claim 1 , further comprising a rounded top on the struts, wherein the rounded top is configured to engage one or more channel members coupled to the bottom of the removable screen panel, wherein the one or more channels are configured to allow vertical displacement of the screen relative to the support frame but prevent horizontal movement of the screen relative to the support frame.

3. The screening assembly support frame of claim 1 , wherein the support frame is molded from a synthetic plastic.

4. The screening assembly support frame of claim 3 , wherein the synthetic plastic is a polyurethane.

5. The screening assembly support frame of claim 1 , further comprising a steel reinforcing structure located within the support frame.

6. The screening assembly support frame of claim 5 , wherein the steel reinforcing structure is located within the support members and the struts and has substantially the same shape as the support members and the struts.
