Adapter for remotely supporting and actuating a power tool from an end of a hot stick
View Patent ↗A remote adapter for use with a lineman's hot stick that enables the lineman to mount a wide variety of power tools onto the far end of the hot stick for tasks involving high voltage equipment. The remote adapter allows the power tool to be actuated by pulling on an insulating pull-rope. The remote adapter includes a body for supporting the power tool, the body including: at least one slot for receiving at least one strap configured to strap the power tool to the body, at least one pivot hole for receiving a pivot pin, and a splined universal connector for attachment to a hot stick. The remote adapter also includes a lever arm that is pivotable with respect to the body. The lever arm includes a hole for receiving a trigger pin which actuates the power tool trigger when the insulating rope attached to an attachment feature is pulled.
1. An adapter, configured to be coupled to a power linesman's hot stick, for remotely supporting and controlling a power tool used on equipment workpieces energized by high voltage, the adapter comprising:
a body configured to support the power tool, the body including:
a first portion terminating at a first end of the body configured to receive and secure the power tool; and
a second portion terminating at a second end of the body having a plurality of body pivot holes, a universal connector disposed at the second end, the universal connector configured to be detachably connected to a universal head of the hot stick;
an actuator arm for remotely actuating a trigger mechanism of the power tool, the actuator arm including a pull member and a trigger member commonly joined together at a vertex of a fixed angle formed therebetween, wherein:
the pull member has an attachment feature disposed proximally to a first terminating end of the actuator arm by which to couple a non-conductive pull member for applying a rotational force to the first terminating end,
the trigger member has a trigger pin disposed at a second terminating end of the actuator arm, and
an arm pivot hole disposed through the actuator arm at the vertex of the angle formed between the pull member and the trigger member; and
a pivot pin configured to be disposed through and rotatably secured within the arm pivot hole and a selected one of the plurality of body pivot holes,
wherein the actuator arm is configured to actuate the power tool by applying a pulling force to the pulling member to rotatably pivot the actuator at the pivot pin until the trigger pin contacts the trigger mechanism of the power tool and the rotational force caused by the pulling force closes the trigger mechanism.
2. The adapter of claim 1 , wherein at least two pivot pin retaining rings are coupled to the pivot pin for rotatably fastening the pivot pin to the body and thereby retain the pivot pin within the selected body pivot hole.
3. The adapter of claim 1 , wherein the trigger pin is disposed through a trigger pin hole located at the second terminating end of the actuator arm and is retained therein by at least one trigger pin retaining ring for fastening the trigger pin to the actuator arm.
4. The adapter of claim 1 , wherein the selected one of the body pivot holes locates the vertex of the pivot arm along the body to ensure best alignment between the pivot pin and the power tool trigger mechanism by which to actuate the power tool.
5. The adapter of claim 1 , wherein the body is configured to accommodate the securing thereto of the power tool having a battery pack.
6. The adapter of claim 1 , wherein:
the body is curved to receive a similarly curved surface of the power tool, and
the power tool is secured with at least one of the following: a strap, a hose clamp, a zip tie, an elastic band, and a hook and loop material strap assembly.
7. The adapter of claim 6 , wherein the universal connector of the adapter and the universal head of the hot stick are both splined.
8. The adapter of claim 1 , wherein the pivot pin is rotatably retained within the arm pivot hole and the body pivot hole by at least three pivot pin retaining rings, with one of the three pivot retaining rings being located proximally to the actuator arm, and two others of the three pivot pin retaining rings being located at each end of the body hole and proximally to the body, thereby maintaining the body and the actuator arm at a fixed distance from one another.
9. The adapter of claim 1 , wherein when the adapter is coupled to a hot stick, the power tool is configured to be positioned with respect to the workpiece using one hand, and the power tool is configured to be actuated with the other hand of a user.
10. The adapter of claim 1 , wherein the non-conductive control attachment a pull rope.
11. The adapter of claim 1 , wherein the power tool is secured with a plurality of straps, each of the plurality of straps configured to be received by at least one slot disposed through a strap portion.
