Abstract
A ladder arm(s) for use in combination with a ladder having an open ended tubular rung with an irregular inner surface to support a container. The ladder arm has an elongate body member to be slideably received in the rung and having a first end and a second end with a frictional device at the first end and a torque applying and retaining handle at the second end. Torque applied to the handle causes the frictional device to lock against the inner surface of the rung thus providing a holding support for a container with handle. There can be provided a bracket between the ladder arm and the container especially where smaller containers with no handle are used. There also can be provided two hangers one on a ladder arm supported in each open end of the rung. There is supported by the two hangers a tray type container fixed to the hangers.

The combination with an aluminum type ladder having side rails carrying hollow rungs with open ends and an irregular inner surface, of at least one of, one or more ladder arms for supporting a handled container including an elongate substantially cylindrical body member slideably received and locked in one or more of said open ends of said hollow rungs, locking means carried near a first end of each of said elongate substantially cylindrical body members and a torque applying and retaining knob shaped for ease of torque application located adjacent a second end of each of said elongate substantially cylindrical body members, said locking means being rigid in structure and integrally joined to each of said elongate substantially cylindrical body members whereby upon rotational torque being applied to said torque applying and retaining knob said locking means is rotated about an elongate axis of said elongate substantially cylindrical body member thereby forcing said locking means into locking engagement with said irregular inner surface in such a manner as to easily and securely hold said handled container against said side rail for stabilized support.
A unitary ladder arm type of support for use with a ladder having side rails carrying hollow rungs with open ends and an irregular inner surface, said ladder arm type of support having a torque applying and retaining means, said ladder arm support having an elongate substantially cylindrical body member, and said ladder arm type of support having a locking means, said elongate substantially cylindrical body member includes a first end and a second end and further includes a central longitudinal axis for rotation thereabout, said torque applying and retaining means integral with and located at said second end including outer peripheral projections for effective hand manipulation when rotating said unitary ladder arm type of support about said central longitudinal axis and having a retaining innermost end surface inwardly of said second end for engaging objects such as a container handle, said locking means being integral with said elongate substantially cylindrical body member near said first end thus providing a complete integral unit that will when inserted in and locked to one of said rungs support a variety of objects, wherein said locking means are made integral with said elongate substantially cylindrical body member by screw thread means.
