Embodiment Construction

[0033] Referring now to the drawings, an example of a tool 20 commonly referred to as a "live stick" is shown. Tool 20 is configured to allow a user to manipulate a piece of equipment from a selected distance away from a workpiece. For example, in an embodiment, tool 20 may be suitable for electrical use up to 600 volts according to ASTM and CSA standards. Alternatively, the tool may be suitable for electrical use up to 750 or 1000 volts.

[0034] As shown, the tool 20 includes a telescoping arm 22 having a plurality of tubular sections 24 that are slidable along the longitudinal axis X of the tool 20 to vary its length. In the non-limiting embodiment shown, the arm 22 includes a retractable position ( figure 2 ) and extended position ( image 3 ) moving between the first tubular section 24a and the second tubular section 24b. Although an arm 22 having only two tubular sections 24a, 24b is shown and described herein, it should be understood that an arm 22 having any numbe...

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.

Description

Background technique [0001] The subject matter disclosed herein relates to personal safety equipment, and more particularly, the disclosure relates to a hand-held spreading tool for electrical applications. [0002] Hand-held electrical detectors are known in the art for detecting the presence of an AC signal potential on a conductor. One type of detector requires direct electrical contact with an uninsulated portion of the conductor. There are safety risks associated with contact type detectors due to the possibility of harmful electrical shock to the user. Contents of the invention [0003] According to one embodiment, a live joystick for manipulating a probe from a position selected a distance away from a workpiece, the tool comprising an arm; a connector coupled to the arm, the connector comprising a connection having a contoured first surface a connector body; and a mechanism movable relative to the connector body and configured to cooperate with the first surface of ...
