An extension pole suitable for use in light bulb changing operations. The extension pole comprises first, second, and third telescopically intercoupled sections. A first locking assembly selectively locks the first and second sections to one another, and a second locking assembly selectively locks the second and third section to one another. The extension pole is made entirely of non-conductive materials to thereby reduce the risk of electrical shock to the operator.

The invention claimed is: 1. An extension pole comprising: first, second, and third telescopically intercoupled sections; a first locking assembly for selectively locking the first and second sections; a second locking assembly for selectively locking the second and third sections; and a first stop including a first head and a first projection extending from the first head, said second section including a first side wall defining a first opening, said first projection extending through the first opening, said first projection having a first distal portion extending past the first side wall, said first head and said first distal portion being disposed on generally opposite sides of the first side wall, said extension pole being shiftable between a fully retracted position where the extension pole has a minimum length and a fully extended position where the extension pole has a maximum length, said first head engaging the first locking assembly when the extension pole is in the fully extended position to thereby prevent further extension of the second section relative to the first section, said first distal portion engaging the third section when the extension pole is in the fully retracted position to thereby prevent further retraction of the third section relative to the second section, said first locking assembly including a first fixed member rigidly coupled to the first section and a first collet disposed around and threadably coupled to the first fixed member, said first fixed member presenting a radial shoulder that engages the first head when the extension pole is in the fully extended position. 2. The extension pole of claim 1, said first head being disposed generally between the first and second sections. 3. The extension pole of claim 2, said first head contacting both the first and second sections. 4. The extension pole of claim 3, said first head having a generally actuate shape. 5. The extension pole of claim 1, said first fixed member including a plurality of resilient first fingers for frictionally engaging the second section, said first collect being operable to vary the amount of friction between the first fingers and the second section via rotation of the first collect relative to the first fixed member. 6. The extension pole of claim 1; and a second stop including a second head and a second projection extending from the second head, said third section including a second side wall defining a second opening, said second projection extending through the second opening, said second projection having a second distal portion extending past the second side wall, said second head and said second distal portion being disposed on generally opposite sides of the second side wall. 7. The extension pole of claim 6, said second head being disposed between the first and second side walls. 8. The extension pole of claim 7, said second head contacting both the first and second side walls. 9. The extension pole of claim 6, said second head engaging the second locking assembly when the extension pole is in the fully extended position to thereby prevent further extension of the third section relative to the second section. 10. An extension pole comprising: first, second, and third telescopically intercoupled sections; a first locking assembly for selectively locking the first and second sections; a second locking assembly for selectively locking the second and third sections; a first stop including a first head and a first projection extending from the first head, said second section including a first side wall defining a first opening, said first projection extending through the first opening, said first projection having a first distal portion extending past the first side wall, said first head and said first distal portion being disposed on generally opposite sides of the first side wall, said extension pole being shiftable between a fully retracted position where the extension pole has a minimum length and a fully extended position where the extension pole has a maximum length, said first head engaging the first locking assembly when the extension pole is in the fully extended position to thereby prevent further extension of the second section relative to the first section, said first distal portion engaging the third section when the extension pole is in the fully retracted position to thereby prevent further retraction of the third section relative to the second section; and a second stop including a second head and a second projection extending from the second head, said third section including a second side wall defining a second opening, said second projection extending through the second opening, said second projection having a second distal portion extending past the second side wall, said second head and said second distal portion being disposed on generally opposite sides of the second side wall, said second head engaging the second locking assembly when the extension pole is in the fully extended position to thereby prevent further extension of the third section relative to the second section, said second locking assembly including a second fixed member rigidly coupled to the second section and a second collect disposed around and threadably coupled to the second fixed member, said second fixed member presenting a radial shoulder that engages the second head when the extension pole is in the fully extended position. 11. An extension pole comprising: first and second telescopically intercoupled sections; a locking assembly for selectively locking the first and second sections; and a stop including a head and a projection extending from the head, said second section including a side wall defining an opening, said projection extending through the opening, said projection having a distal portionextending past the side wall, said head and said distal portion being disposed on generally opposite sides of the side wall, said extension pole being shiftable between a fully retracted position where the extension pole has a minimum length and a fully extended position where the extension pole has a maximum length, said head engaging the locking assembly when the extension pole is in the fully extended position to thereby prevent further extension of the second section relative to the first section, said locking assembly including a fixed member rigidly coupled to the first section and a collect disposed around and threadably coupled to the fixed member, said fixed member presenting a radial shoulder that engages the head when the extension pole is in the fully extended position. 12. The extension pole of claim 11, said head being disposed generally between the first and second sections. 13. The extension pole of claim 12, said head contacting both the first and second sections. 14. The extension pole of claim 13, said head having a generally actuate shape. 15. The extension pole of claim 11, said fixed member including a plurality of resilient fingers for frictionally engaging the second section, said collect being operable to vary the amount of friction between the fingers and the second section via rotation of the collect relative to the fixed member.
