Abstract: An arm which is hook shaped and has a vertical section and a foot section is secured in brackets which are attached to a wall of a support structure. The brackets are of sheet metal and are formed with opposed arcuate portions which define bearing surfaces. The vertical section of the arm is captured within the bearing surfaces by bolts which extend through the sides of the U-shaped members near their open ends. Pins and slots are provided in the U-shaped members and in the vertical section of the arm whereby the arm is supported with its foot section extending outwardly from the wall for carrying articles. By moving the arm vertically with respect to the U-shaped members so that the slots and pins clear each other, the arm may be rotated to a stowed position adjacent to the wall. Pluralities of such hook shaped arms may be attached to the wall, spaced horizontally from each other, for supporting heavy articles such as bicycles, boards and the like.
