Removable step climbing assembly

In combination with an upwardly extending, substantially vertical member of sufficient strength to support a person thereon, a step climbing assembly, said assembly including:

• a. a plurality of longitudinally spaced pairs of brackets that are alternately situated as on opposite sides of said member, with the brackets in each of said pairs longitudinally spaced from one another, and the two brackets in each of said pairs defining two coaxially aligned, longitudinally extending confined spaces;
• b. first means for rigidly securing said brackets to said elongate member;
• and
• c. a pair of step defining units, with each of said units including two longitudinally spaced coaxially aligned first and second flanges that extend in the same direction and may be removably inserted in said confined spaces of two of said pairs of brackets on opposite sides of said member that are adjacently disposed to support the feet of said person climbing said member, with said step defining units as said person climbs up or down said member being sequentially disengaged one by one from said pair of brackets and caused to removably engage the next unengaged pair of said brackets in the direction in which said person is climbing to support said person on said member, with each of said step defining units having an elongate rigid metallic strap that has first and second end portions, with the part of said strap intermediate said first and second end portions being bent to define a shoe supporting section and an angular section, with said first and second flanges being defined by said first and second end portions that are bent relative to the free ends of said first receiving section and said angular section.
