How to couple two poles to make a quick extension pole? (wood, metal,
or plastic)

Problem: Couple/join 2-3/4" dia 5' long poles to make a 10' extension
pole that will not twist slip but which may easily pull apart?

Fewest parts, easy and inexpensive to manufacture.

Ideas??

Application? Will not twist? How much torque in each direction?
Easily pull apart as in? just pull back, or manually disconnect?
More details man - there's at least a thousand ways of doing something
that MIGHT fit your reqiuirements.

Light pole changer. Must twist in both directions.

Bring down bulb from 15' ceiling.

Place 10' pole on floor.

Remove upper 5' pole.

Place upper pole on floor.

Remove bulb.

Why not use a tension cord and a tab and slot arrangement or pin and
slot. The tension cord holds ittogether, you pull it apart and fold it
so you don't have to go chase the bottom end when it rolls across the
floor.
3/4" tubing with a "plug" screwed, glued or rivetted in one end,
with"tits" sticking out the side Slot cut in end of second pole which
fits snuggly, but not tight over the protruding plug. Tension cord run
through center of plug from end to end of combined pole.

Not a bad idea.

However the tension cord prevents the user from separating the 2
halves should they require only a 5' pole.

The tab and slot is where my thinking is going.

Let's start with 2 - 3/4" Dia wood poles.

Drill a hole for a 1/4" dowel into both.

Remember, there is to bending force, only compression.

Dado cut across the ends forming 2 slots and 2 tabs in both.

Place loose fitting dowel with glue into 1.

(You could start off with tubing and do the same.)

Done!

What do you think?
