Abstract

A hot stick for manipulating a probe from a position a selected distance away from a workpiece, the tool including an arm, a connector coupled to the arm, the connector including a connector body having a contoured first surface, and a mechanism movable relative to the connector body and configured to cooperate with the first surface of the body to retain a probe.

First claim

What is claimed is:

1. A hot stick for manipulating a probe from a position a selected distance away from a workpiece, the tool comprising:
an arm;
a connector coupled to the arm, the connector including a connector body having a contoured first surface; and
a mechanism mounted at an exterior surface the connector body, the mechanism being movable relative to the connector body to cooperate with the first surface to retain a probe, the mechanism being slidable within a channel formed in the connector body and extending generally perpendicular to a longitudinal axis of the arm, the mechanism being selectively retained at a plurality of locations relative to the connector body.

2. The hot stick of claim 1 , wherein the hot stick is suitable for use in applications where the workpiece has 1000 volts or less.

3. The hot stick of claim 1 , wherein the hot stick is suitable for use in applications where the workpiece has 600 volts or less.

4. The hot stick of claim 1 , wherein the arm is a telescoping arm comprising a plurality of sections movable between a retracted position and an extended position.

5. The hot stick of claim 4 , wherein a resilient locking mechanism retains the arm in one of the extended position and the retracted position.

6. The hot stick of claim 1 , wherein a gripping material is positioned adjacent a first end of the arm.

7. The hot stick of claim 1 , wherein the arm, connector, and mechanism are formed from a non-conductive material.

8. The hot stick of claim 1 , wherein the mechanism includes an engagement portion located generally adjacent the first surface of the connector body, at least one of the engagement portion and the first surface having an insert for gripping the probe coupled thereto.

9. The hot stick of claim 1 , wherein the connector body includes an elongated member operable to translate a button along an axis.

10. The hot stick of claim 9 , wherein the button is an inspection button of an elevator.

11. The hot stick of claim 1 , wherein the connector body includes at least one feature operable to rotate a button about an axis.

12. The hot stick of claim 11 , wherein the at least one feature includes a substantially identical first feature and second feature, the first feature and the second feature being generally symmetrical about a corresponding surface of the connector body.

13. The hot stick of claim 12 , wherein the second feature is rotated 180 degrees relative to the first feature.

14. The hot stick of claim 12 , wherein a clearance is defined between the first feature and the second feature, the clearance being complementary to a channel of the button.

15. The hot stick of claim 1 , wherein the connector is fixedly attached to an end of the arm.

16. The hot stick of claim 1 , wherein the connector is integrally formed with an end of the arm.
