Portable storage support structure adapted for resting on a floor and leaning against a wall includes elongated first and second members having a bend so as to together define a plane, and a support bar secured to the upper one of the members which lies within the plane and extends generally orthogonally to a major axis of the upper member. The length of the support bar is shorter than the projection of the lower member away from the upper member major axis so that the center of gravity remains between the distal end of the lower member and the wall. The...
Portable storage support structure adapted for resting on a horizontal surface and leaning against a vertical surface, comprising: an elongated first member having a major axis oriented generally vertically, said first member having an upper end and a lower end; an elongated second member secured to the lower end of said first member and extending downwardly and away from said major axis of said first member so that said first and second members together define a first plane; a support bar; means for securing said support bar to said first member between...
