and in turned toes 2 the angle u03b1 between toes 2 and upright 3 exceeds 90 u00b0 so that the frames when connected to base 10 as will be described below are normally splayed slightly outwardly as best seen from the side view of fig2 base 10 includes at each of its corners 11 a tubular bracket 7 that acts both as a ground engaging foot and as a connector for toes 2 in this regard the inner diameter of each bracket 7 is sized to slidably but closely engage a respective one of toes 2 therein for a firm friction fit assembly of the holder is quickly and easily completed simply by inserting toes 2 into cooperating ones of brackets 7 one edge of liner 39 s 15 open end is looped over one of flanges 6 with an opposing edge portion then looped over the flange of opposite frame member 5 the dimensions of most commercially available liners are such that when connected to the holder as described above frames 5 are drawn together which biases flanges 6 against the contiguous portions of the liner this tensioning holds the liner in a fully opened condition and also helps to firmly secure the liner to the holder without the use of extraneous clips or clamps even as the bag 39 s load increases bracket 7 can be made of tubular metallic.
