Extension pole for tools

An extension pole for tools, comprising:

• an elongate, tubular handle portion having a hollow interior, the handle portion having a distal end;
• an elongate, tubular extension portion having a hollow interior and a longitudinally disposed external keyway, the keyway having a floor, a plurality of spaced apart lock pin holes being defined in the floor;
• said extension portion having a thicker wall than said handle portion and having a plurality of stiffener ribs extending longitudinally in the interior of said extension portion, for resisting bending of said extension portion;
• said extension portion telescopingly disposed within said handle portion for selectively adjusting said extension portion relative to said handle portion as desired, with said handle portion and said extension portion defining a variable total length;
• said extension portion having a proximal end slidably disposed in said handle portion and having a distal end;
• lock pin assembly, including:
• a cylindrical sleeve permanently attached to the distal end of said handle portion;
• a lock pin housing extending radially from said sleeve;
• a lock pin having a shaft extending through said lock pin housing and through said sleeve, the lock pin having a button at one end of the shaft disposed outside of said lock pin housing and having a collar disposed about the shaft inside said lock pin housing;
• and
• a helical compression spring concentrically disposed around the lock pin shaft between the lock pin housing and the lock pin collar, the spring biasing the lock pin shaft against the floor of the keyway and through one of the holes defined in the keyway;
• a tab integral with and extending from the distal end of said handle portion into the keyway, the tab preventing rotation of said extension portion relative to said handle portion and maintaining said lock pin in alignment with the keyway;
• a stop pin at the proximal end of said extension portion extending into the keyway, said stop pin engagable with said tab in order to prevent the proximal end of said extension portion from separating from said handle portion;
• and
• a threaded pin extending from the distal end of said extension portion, the threaded pin having Acme external threads for attachment of a tool having an internally threaded fitting, and having an internally threaded bore defined therein for attachment of a tool having an externally threaded fitting.
