Patent ID: 8469426

Claim:
An extension tool, comprising: a first pole defining an interior bore and a first exterior surface with said first pole extending between a first end and a second end; a second pole defining a second exterior surface with said second pole extending between a first end and a second end; a first bushing defining an internal bore and an exterior surface; a second bushing defining an internal bore and an exterior surface; said second pole being partially disposed in said first pole with said internal bore of said first bushing slidably engaging with said exterior surface of said second pole and with said exterior surface of said second bushing slidably engaging with said internal bore of said first pole for enabling said second pole to be slidably displaced relative to said first pole; a plurality of apertures defined in said second pole; a pin mounted to said first pole for movement between a retracted position and a protruded position; a spring for biasing said pin into said protruded position for extending into a selected one of said plurality of apertures of said second pole for fixing the position of said second pole relative to said first pole; a pin lever for moving said pin into said retracted position for permitting displacement of said first pole relative to said second pole; and an upper telescoping stop comprising said first bushing cooperating with said second bushing to limit an outward movement of said second pole relative to said first pole upon engagement of said first bushing with said second bushing.
