Multi-sectional nut and adjustable length pole incorporating such nut

A nut assembly comprising:

• a. a bushing having a through, axial bore with a central axis;
• b. at least two elongated legs each having a surface portion formed with threads;
• and
• c. means for mounting said legs upon said bushing for movement of said legs between a first position, wherein said threads of each of said surface portions are spaced a first distance outwardly of said central axis, and a second position, wherein said threads of each of said surface portions are spaced a second distance outwardly of said central axis.

A pole assembly of selectively adjustable axial length comprising:

• a. first and second, elongated, hollow rods arranged for coaxial, telescoping, relative, axial movement to adjust said axial length;
• b. an externally threaded shaft fixedly and coaxially mounted within said first rod and extending into said second rod;
• c. a first bushing having a first, through bore;
• d. a second bushing having a second, through bore;
• e. an internally threaded nut mounted to said first bushing and divided into at least two, physically separate sections, each having a first surface portion with threads mateable with said threaded rod;
• and
• f. cooperable surfaces on each of said sections and said second bushing for movement of said sections between first and second positions wherein said first and second surface portions are in and out, respectively, of threaded engagement with said threaded shaft, in response to relative, axial movement of said first and second bushings.
