A hands-free system for connecting and disconnecting a tool from an adjustable length extension pole. The system includes first and second slidably interconnected elongated members, a tool-holding assembly releasably coupled to the second elongated member, and a locking assembly disposed between the first and second elongated members. The relative sliding of the first and second elongated members can be selectively restrained by rotating the first and second elongated members relative to one another. The tool-holding assembly can be disconnected from the second elongated member by sliding the first and second elongated members together.

1. An extended reach apparatus, said apparatus comprising: a first elongated member;a second elongated member slidably intercoupled with the first elongated member;a working tool assembly releasably coupled to the second elongated member;a catch assembly including a releasable catch that is associated with one of said second elongated member and said working tool assembly, and that removably couples the working tool assembly to the second elongated member,said catch being releasable from a locking condition, in which the catch securely locks the working tool assembly to the second elongated member such that decoupling of the working tool assembly from the second elongated member is restrained until the catch is released,said first and second elongated members being slidable relative to one another into a tool disconnect condition, thereby causing the catch to be automatically released from the locking condition to thereby decouple the working tool assembly from the second elongated member; anda locking assembly disposed between the first and second elongated members, said locking assembly being selectively actuatable to restrain relative sliding of the first and second elongated members. 2. The apparatus as claimed in claim 1, said first and second elongated members being telescopically intercoupled. 3. The apparatus as claimed in claim 2, said first elongated member being telescopically received in the second elongated member. 4. The apparatus as claimed in claim 3, said first and second elongated members comprising respective substantially cylindrical tubes. 5. The apparatus as claimed in claim 1, said locking assembly being actuatable by rotating the first and second elongated members relative to one another. 6. The apparatus as claimed in claim 5, said locking assembly including a lock body fixedly coupled to one of the elongated members and an expandable lock collar rotatably coupled to the lock body, said lock collar exerting a locking force on the other of the elongated members when the locking assembly is actuated. 7. An extended reach apparatus, said apparatus comprising: a first elongated member;a second elongated member slidably intercoupled with the first elongated member;a working tool assembly releasably coupled to the second elongated member; anda catch assembly including a releasable catch that is associated with one of said second elongated member and said working tool assembly, and that removably couples the working tool assembly to the second elongated member,said catch being releasable from a locking condition, in which the catch securely locks the working tool assembly to the second elongated member such that decoupling of the working tool assembly from the second elongated member is restrained until the catch is released,said first and second elongated members being slidable relative to one another into a tool disconnect condition, in which the catch is automatically released from the locking condition to thereby decouple the working tool assembly from the second elongated member,said tool disconnect condition being defined by the first elongated member operably contacting the catch assembly to automatically release the catch from the locking condition,said releasable catch including a resilient latch associated with the working tool assembly, said catch assembly further including a latch-receiving slot defined in the second elongated member. 8. The apparatus as claimed in claim 7, said resilient latch having an angled contact surface so that when the first elongated member is contacted with and forced to move relative to the angled contact surface the latch is shifted out of the slot, thereby releasing the catch and decoupling the working tool assembly from the second elongated member. 9. The apparatus as claimed in claim 8, said resilient latch being resiliently flexed when shifted away from a latched position, wherein the latch is disposed for receipt within the slot,said resilient latch being shifted away from the latched position when the second elongated member is contacted with and forced to move relative to the angled contact surface of the latch as the working tool assembly is coupled to the second elongated member, whereupon the resilient latch returns to the latched position and is received within the slot, thereby coupling the working tool assembly to the second elongated member. 10. The apparatus as claimed in claim 1, said first and second elongated members being slidable relative to one another to define fully extended and fully contracted positions,said tool disconnect condition corresponding to the first and second elongated members being slid together to the fully contracted position. 11. An extended reach apparatus, said apparatus comprising: a first elongated member;a second elongated member slidably intercoupled with the first elongated member;a working tool assembly releasably coupled to the second elongated member; anda catch assembly including a releasable catch that is associated with one of said second elongated member and said working tool assembly, and that removably couples the working tool assembly to the second elongated member,said catch being releasable from a locking condition, in which the catch securely locks the working tool assembly to the second elongated member such that decoupling of the working tool assembly from the second elongated member is restrained until the catch is released,said first and second elongated members being slidable relative to one another into a tool disconnect condition, thereby causing the catch to be automatically released from the locking condition to thereby decouple the working tool assembly from the second elongated member,said catch assembly including a latch and a latch-receiving slot, one of which is associated with the working tool assembly and the other of which is associated with the second elongated member,said latch being shiftable between a latched position and an unlatched position, with said latch being received within the slot to thereby secure the working tool assembly to the second elongated member when in the latched position, and said latch being removed from the slot to thereby permit decoupling of the working tool assembly from the second elongated member when in the unlatched position. 12. The apparatus as claimed in claim 11, said latch being shifted from the latched position to the unlatched position upon operable contact by and movement of the first elongated member relative to the latch as the first and second elongated members are slid relative to one another into the tool disconnect condition, thereby releasing the catch and decoupling the working tool assembly from the second elongated member. 13. The apparatus as claimed in claim 12, said latch being automatically shifted into the latched position as the working tool assembly is coupled to the second elongated member, thereby securing the working tool assembly to the second elongated member.
