ABSTRACT:
A foldable trestle for supporting a flexible drain conduit is formed of four or more stretcher sections connected end-to-end by hinge sections. The stretcher sections each comprise a pair of angle members with upright flanges spaced apart at each end by a crosswise hinge member. The hinge member connecting the first and second stretcher sections is a single-pin hinge; the hinge members connecting the second and third sections and the remaining hinge members are double-pin hinges. For storage the first and second sections are folded back-to-back around the pin of their hinge. The spacing between pins of the second hinge is sufficient to permit the third stretcher section to be folded parallel to the second stretcher section but spaced therefrom so as to enclose the folded first stretcher section. The spacing between pins of the third hinge is sufficient to permit the fourth stretcher section to be folded parallel to the third stretcher section but spaced therefrom so as to envelope the folded together first and second stretcher sections, and so on. U-shaped ground support members are pivotally mounted at their open ends to the first and last stretcher sections respectively so as to fold into alignment with those sections respectively.
