Abstract

A hot stick accessory with an attachment interface engageable with multiple types of attachment interfaces, including a shotgun-type attachment interface and a universal-type attachment interface. The accessory includes any of several operative components, such as a knife. The interface includes an attachment member with a first aperture and a plurality of second apertures arranged in an arc shape about the first aperture.

First claim

What is claimed is:

1. An attachment for a hot stick comprising:
an operative component;
a handle rigidly coupled to the operative component; and
an attachment component rigidly coupled to the handle, the attachment component comprising:
a hook receptacle configured to receive a shotgun-type hot stick attachment interface, the hook receptacle has a length between 11.6 mm and 12.0 mm along a first axis and between 12.0 mm and 12.4 mm along a second axis perpendicular to the first axis, the hook receptacle is defined in part by an arc-shaped component extending from an end of the hook receptacle, an outer peripheral edge of the arc-shaped component is between 9.85 mm and 10.25 mm from a center point;
a plurality of teeth receptacles configured to receive a universal-type attachment interface, wherein:
the plurality of teeth receptacles are arranged in an arc around the hook receptacle;
side edges of each of the plurality of teeth receptacles are radially aligned with the center point, the side edges of a given teeth receptacle are 15 arc degrees apart with respect to the center point, and neighboring side edges of neighboring teeth receptacles are 15 arc degrees apart with respect to the center point; and
an interior edge of each of the plurality of teeth receptacles is between 9.85 mm and 10.25 mm from the center point.

2. The attachment of claim 1 , wherein an outer peripheral edge of the arc is 10.05 mm from the center point.

3. The attachment of claim 2 , wherein the interior edge of each of the plurality of teeth receptacles is 10.05 mm from the center point.

4. The attachment of claim 1 , wherein the operative component comprises a blade.

5. The attachment of claim 1 , wherein the hook receptacle has a length of 11.8 mm along the first axis and 12.2 mm along the second axis.

6. An elongated tool comprising:
an elongated structure;
an attachment member detachably engaged with a first end of the elongated structure, the attachment member comprising:
a blade;
an attachment component rigidly coupled to the blade, the attachment component comprising:
a hook receptacle defined in part by an arc-shaped component extending from an end of the hook receptacle, an outer peripheral edge of the arc-shaped component is between 9.85 mm and 10.25 mm from a center point located within the hook receptacle, the hook receptacle has a length between 11.6 mm and 12.0 mm along a first axis and between 12.0 mm and 12.4 mm along a second axis perpendicular to the first axis; and
a plurality of teeth receptacles, wherein:
the plurality of teeth receptacles are arranged in an arc around the hook receptacle;
side edges of each of the plurality of teeth receptacles are aligned with the center point and the side edges of a given teeth receptacle are 15 arc degrees apart with respect to the center point; and
an interior edge of each of the plurality of teeth receptacles is between 9.85 mm and 10.25 mm from the center point.

7. The elongated tool of claim 6 , wherein neighboring side edges of neighboring teeth receptacles are 15 arc degrees apart with respect to the center point.

8. The elongated tool of claim 6 , wherein the plurality of teeth receptacles comprise five teeth receptacles.

9. The elongated tool of claim 6 , wherein the attachment member comprises a handle, and wherein the blade and the attachment component are rigidly coupled to opposing ends of the handle.

10. A method of using a hot stick attachment comprising:
engaging a first hot stick with a hot stick attachment, the first hot stick comprising a first attachment interface, the hot stick attachment comprising:
an operative component;
an attachment component rigidly coupled to the operative component, the attachment component comprising:
a hook receptacle that receives the first attachment interface of the first hot stick, the hook receptacle is defined in part by an arc-shaped component extending from an end of the hook receptacle, an outer peripheral edge of the arc-shaped component is 10.05 mm from a center point located within the hook receptacle, the hook receptacle has a length between 11.6 mm and 12.0 mm along a first axis and between 12.0 mm and 12.4 mm along a second axis perpendicular to the first axis;
a plurality of teeth receptacles, wherein:
the plurality of teeth receptacles are arranged in an arc around the hook receptacle;
side edges of each of the plurality of teeth receptacles are aligned with the center point and the side edges of a given teeth receptacle are 15 arc degrees apart with respect to the center point; and
an interior edge of each of the plurality of teeth receptacles is 10.05 mm from the center point;

disengaging the hot stick attachment from the first hot stick; and
engaging the hot stick attachment with a second hot stick comprising a second attachment interface that engages with the plurality of teeth receptacle.

11. The method of claim 10 , wherein the first attachment interface of the first hot stick is a shotgun-type interface and the second attachment interface is a universal-type attachment interface.

12. The method of claim 10 , the method further comprising:
disengaging the hot stick attachment from the second hot stick;
engaging the hot stick attachment with a third hot stick comprising a third attachment interface that engages with the plurality of teeth receptacles, the second attachment interface of the second hot stick is a universal-type interface and the third attachment interface of the third hot stick is a universal-type attachment interface.

13. The method of claim 10 , wherein the plurality of teeth receptacles comprise five teeth receptacles.

14. A method of using a hot stick attachment comprising:
engaging a first hot stick with a hot stick attachment, the first hot stick comprising a first attachment interface, the hot stick attachment comprising:
an operative component;
an attachment component rigidly coupled to the operative component, the attachment component comprising:
a hook receptacle that receives the first attachment interface of the first hot stick, the hook receptacle is defined in part by an arc-shaped component extending from an end of the hook receptacle, an outer peripheral edge of the arc-shaped component is 10.05 mm from a center point located within the hook receptacle, the hook receptacle has a length of 11.8 mm along a first axis and 12.2 mm along a second axis perpendicular to the first axis;
a plurality of teeth receptacles, wherein:
the plurality of teeth receptacles are arranged in an arc around the hook receptacle; and
side edges of each of the plurality of teeth receptacles are aligned with the center point and the side edges of a given teeth receptacle are 15 arc degrees apart with respect to the center point; and
and an interior edge of each of the plurality of teeth receptacles is 10.05 mm from the center point disengaging the hot stick attachment from the first hot stick; and

engaging the hot stick attachment with a second hot stick comprising a second attachment interface that engages with the plurality of teeth receptacles.

15. The method of claim 14 , wherein the first attachment interface of the first hot stick is a shotgun-type interface and the second attachment interface is a universal-type attachment interface.

16. The method of claim 14 , the method further comprising:
disengaging the hot stick attachment from the second hot stick;
engaging the hot stick attachment with a third hot stick comprising a third attachment interface that engages with the plurality of teeth receptacles, the second attachment
