mate the shaft of the second extension element 40 in a u201c flush u201d fashion without having to be flush with the second end 24 of the first extension element thus the connector 30 of the present invention permits multiple axial locations relative to the first and second extension element for a more flexible arrangement for securing the fan blade than might be used in a convention u201c nut and bolt u201d relationship the connector 30 is disposed between the first and second connector elements 20 40 to accommodate the user with a hand adjustable connection or a tool connection e g a wrench in other words to operate this preferred embodiment of the present invention the connector 30 is screwed onto the male thread 42 of an extension element located in the example of fig1 and 2 on the first end 42 of second extension element 40 with that male thread 42 then mating with the reciprocal female thread 26 of the first extension element 20 the connector 30 and the first and second extension elements 20 40 are then attached screwed together to create the blade arm 10 the user then connects the blade arm 10 to a ceiling fan rotor by inserting screws into the holes at the flange 44 which then are screwed into the ceiling fan rotor a second preferred embodiment further includes the use of a lock nut surface 32 defined on at least a portion of the exterior circumference of connector 30 to facilitate the connection of the extension elements through a tool tightened connection a fan blade not shown is attached screwed onto the flange 22 of the first extension element 20 and the fan blades position can be changed by rotating the blade and securing its position by tightening the.
