[0022] FIG. 1 is a schematic side view of an insulating stick (10) for indirect live wires according to one embodiment.

[0023] Referring to FIG. 1, the indirect live-line insulating stick (10) may include a body (100), a holder (200), a lever (300), and a driving force transmission structure (400). The indirect live-line insulating stick (10) is configured to operate a motor device (PT) mounted on one end.

[0024] The body (100) may be formed in an elongated shape having sufficient length to ensure a distance between the worker and the power line. The body (100) may include an insulating material to prevent an electric shock accident to the worker. The body (100) may include a safety ring (110) that warns the worker's hand not to approach the power line.

[0025] A holder (200) may be attached to one end of the body (100). The holder (200) may hold an electric motor (PT) used in an indirect live-line method. In one embodiment, the holder (200) may be provided with an insertion hole (e.g., the insertion hole (H) in FIG. 2) for receiving a part of the electric motor (PT). A part of the electric motor (PT) (e.g., a handle) may be inserted into and fixed in the insertion hole (H) of the holder (200). Various types, manufacturers, and forms of electric motors (PT) may be inserted into the insertion hole (H) of the holder (200).

[0026] A lever (300) may be attached to one side of the body (100) spaced apart from the holder (200). The lever (300) may include a fastening element (310) and a grip (320).

[0027] The fastening element (310) can be fixed to the body (100) by gripping a part of the body (100). For example, the fastening element (310) may have a through hole through which the body passes and may include a tightening screw (311) to adjust the inner diameter of the through hole to match the diameter of the body (100).

[0028] The grip (320) can be rotatably coupled to the coupling element (310). A first rotation axis (A1) perpendicular to the longitudinal direction of the body (100) can be formed in the central part of the grip (320). Based on the first rotation axis (A1), one side of the grip (320) far from the holder (200) may be a part that the user grips, and the other side close to the holder (200) may be coupled to the driving force transmission structure (400).

[0029] In one embodiment, when a user grasps one side of the grip (320) and pulls it toward the body, the grip (320) can rotate around the first rotation axis (A1) in a direction that tensions the wire (410) of the driving force transmission structure (400) (e.g., counterclockwise in FIG. 1).

[0030] In one embodiment, the driving force transmission structure (400) is coupled to the lever (300) and can transmit driving force to the trigger (TR) of the electric motor (PT). The driving force transmission structure (400) may include a wire (410). The wire (410) may extend from the lever (300) to the holder (200). The wire (410) may include an insulating material, for example, silicone. The wire (410) may be structured such that a tensile force is transmitted to the other end as one end is tensioned. Referring to FIG. 1, when the grip (320) rotates around the first rotation axis (A1) in a direction that tensions one end of the wire (410) coupled to the lever (300) (e.g., counterclockwise in FIG. 1), a tensile force can be transmitted to the other end of the wire (410) connected to the electric motor (PT).

[0031] In one embodiment, the indirect live wire insulating stick (10) may further include a joint (500) disposed between the body (100) and the holder (200). The joint (500) may be coupled to the body (100) and the holder (200), respectively. The body (100) and the holder (200) may rotate by the joint (500), thereby allowing the angle of the holder (200) relative to the body (100) to be adjusted. In one embodiment, the joint (500) may include an angle adjustment screw (510). By loosening the angle adjustment screw (510), the angle between the body (100) and the holder (200) can be adjusted, and by tightening the angle adjustment screw (510) after adjusting the angle, the angle between the body (100) and the holder (200) can be fixed.

[0032] In one embodiment, the indirect live wire insulating stick (10) may include a tension regulator (450) for adjusting the tension of a wire (410). The tension regulator (450) may include a tension bolt (451) and a tension adjustment knob (452) positioned between the wire (410) and the lever (300). The tension bolt (451) may be located at the end of the wire (410) that is coupled to the lever (300). The tension adjustment knob (452) may be attached to the lever (300) and coupled to the tension bolt (451). When the tension adjustment knob (452) coupled to the tension bolt (451) is operated, the tension of the wire (410) may be increased or decreased.

[0033] FIG. 2 illustrates a driving force transmission mechanism of a driving force transmission structure (400) according to one embodiment.

[0034] In one embodiment, the driving force transmission structure (400) may include a wire (410) and a protruding element (420). One end of the wire (410) may be connected to a lever (300) and the other end may be connected to a trigger (TR). The protruding element (420) may be located between the holder (200) and the lever (300). The protruding element (420) may be, for example, cylindrical in shape or have a shape similar to a pulley.

[0035] The protruding element (420) can bend the wire (410) to change the direction of the driving force transmitted by the wire (410). For example, with reference to FIG. 2, the protruding element (420) can bend the wire (410), which extends along the longitudinal direction of the body (100), toward the direction where the trigger (TR) of the electric motor (PT) is located. In one embodiment, the bent wire (410) can be positioned to wrap around and grip the trigger (TR). Thus, when the lever (300) rotates to tension one end of the wire (410), the other end of the wire (410) gripping the trigger (TR) can press the trigger (TR) to operate the electric motor (PT).

[0036] Hereinafter, the operation and operation of an indirect live-line insulating stick (10) according to one embodiment will be described. A user can mount and fix a motor device (PT) in a holder (200) so that the wire (410) can grip the trigger (TR). The user can simultaneously grip one side of the body (100) and the grip (320) with one hand, and if necessary, can grip another part of the body (100) with the other hand. When the user grasps the hand gripping the grip (320) and the body (100), the grip (320) rotates to tension the wire (410), and the wire (410) presses the trigger (TR) to operate the motor device (PT). When the user releases the hand that was gripping, the grip (320) returns to its original position, and one end of the wire (410) that had been pressing the trigger (TR) is no longer subjected to tension, so the operation of the electric motor (PT) can be stopped.

[0037] FIG. 3 illustrates a driving force transmission mechanism of a driving force transmission structure (400) according to one embodiment. The body (100), holder (200), lever (300), and joint (500) may have the same or similar configuration as described with reference to FIG. 1. Therefore, the description of the same or similar components is omitted, and the description will focus on the components that differ.

[0038] In one embodiment, the driving force transmission structure (400) may include a wire (410) and a link (430). One end of the wire (410) may be connected to a lever (300), and the other end may be connected to a trigger (TR) through the link (430). The link (430) may have a shape having at least one bent portion. For example, the link (430) may have an "L" shape in a side view such as FIG. 3, and the angle of the bent portion may be obtuse. The link (430) may have a rectangular shape, for example, when viewed in the -Y direction in FIG. 3. One side of the rectangular shape may be positioned adjacent to the trigger, and the other side parallel thereto may be positioned between the holder (200) and the body (100) and connected to the wire (410). The remaining two sides are positioned on each side of the holder (200), and the central portions of the two sides (i.e., the folded portions) can be rotatably connected to the holder (200).

[0039] The link (430) is rotatably coupled to the holder (200) to change the direction of the driving force transmitted by the wire (410). The link (430) can be rotatably coupled to the holder (200) around the second rotation axis (A2) at the bent portion. The second rotation axis (A2) can be perpendicular to the direction of pressing the trigger (TR) and the longitudinal direction of the body (100). One end of the link (430) connected to the trigger (TR) can wrap around and grip the trigger (TR). Thus, when the grip (320) rotates to tension one end of the wire (410), the link (430) rotates around the second rotation axis (A2), and the other end of the link (430) gripping the trigger (TR) can press the trigger (TR) to operate the electric motor (PT).

[0040] An indirect live wire insulating stick (10) according to one embodiment can prevent the wire (410) from detaching from the trigger (TR) by including a link (430) instead of directly connecting the wire (410) to the trigger (TR).

[0041] Hereinafter, the operation and operation of an indirect live-line insulating stick (10) according to one embodiment will be described. A user can mount and fix a motor device (PT) in a holder (200) so that the link (430) can grip the trigger (TR). The user can simultaneously grip one side of the body (100) and the grip (320) with one hand, and if necessary, can grip another part of the body (100) with the other hand. When the user grasps the hand gripping the grip (320) and the body (100), the grip (320) rotates to tension the wire (410), the wire (410) rotates the link (430), and the link (430) presses the trigger (TR) to operate the motor device (PT). When the user releases the hand that was gripping, the grip (320) returns to its original position, and the link (430) that pressed the trigger (TR) also returns to its original position, so that the operation of the electric motor (PT) can be stopped.

[0042] FIG. 4 illustrates a driving force transmission mechanism of a driving force transmission structure (400) according to one embodiment. The body (100), holder (200), lever (300), and joint (500) may have the same or similar configuration as described with reference to FIG. 1. Therefore, the description of the same or similar components is omitted, and the description will focus on the components that differ.

[0043] In one embodiment, the driving force transmission structure (400) may include a wire (410), a link (430), and a reciprocating link (440).

[0044] One end of the wire (410) is connected to the lever (300), and the other end can be connected to the trigger (TR) via the link (430) and the reciprocating link (440). One end of the link (430) is connected to the wire (410), and the other end can be connected to the reciprocating link (440).

[0045] The link (430) may have a shape having at least one bent portion. For example, the link (430) may have an “L” shape in a side view such as FIG. 4, and the angle of the bent portion may be an angle close to 90 degrees.

[0046] The link (430) may be a reversed "C" shape, for example, when viewed in the -Y direction in FIG. 4. Two parallel sides of the "C" shape may be placed on each side of the holder (200) and connected to the reciprocating link (440) at each end point. The remaining side may be placed between the holder (200) and the body (100) and connected to the wire (410).

[0047] The reciprocating link (440) may be straight in shape in a side view such as FIG. 4. One end of the straight shape may be rotatably connected to the link (430), and the other end may be positioned adjacent to the trigger (TR). The reciprocating link (440) may be "C" shaped, for example, when viewed in the -Y direction in FIG. 4. Two parallel sides of the "C" shape may be accommodated within the holder (200), and the remaining side may wrap around and grip the trigger (TR). In one embodiment, the reciprocating link (440) may include a gripping rod (441) in the part connected to the trigger (TR), so that the trigger may be gripped and pressed through the gripping rod (441).

[0048] The link (430) can be rotatably coupled to the holder (200) to change the direction of the driving force transmitted by the wire (410). The link (430) can be rotatably coupled to the holder (200) around the third rotation axis (A3) at the bent portion. The third rotation axis (A3) can be perpendicular to the direction of pressing the trigger (TR) and the longitudinal direction of the body (100). The reciprocating link (440) can perform linear reciprocating motion in the direction of pressing the trigger in response to the rotation of the link (430). Accordingly, when the grip (320) rotates to tension one end of the wire (410), the link (430) rotates around the third rotation axis (A3), the reciprocating link (440) moves in the direction of pressing the trigger (TR), and the gripping rod (441) of the reciprocating link (440) can press the trigger (TR) to operate the electric motor (PT).

[0049] An indirect live-line insulating stick (10) according to one embodiment can prevent the wire (410) from detaching from the trigger (TR) by including a link (430) and a reciprocating link (440) instead of directly connecting the wire (410) to the trigger (TR). Additionally, if the indirect live-line insulating stick (10) includes the link (430) and the reciprocating link (440) together, the direction of the driving force transmitted to the trigger (TR) by the driving force transmission structure (400) can coincide with the direction of direct pressure on the trigger (TR) (e.g., the +X direction in FIG. 4).

[0050] In one embodiment, the reciprocating link (440) includes a guide hole (G) formed along the direction of linear reciprocating motion, and the holder (200) may include a guide projection (210) received in the guide hole (G). The guide projection (210) may limit the relative motion of the reciprocating link (440) with respect to the holder (200) in the longitudinal direction of the guide hole (G). The guide hole (G) and the guide projection (210) may prevent the gripping rod (441) from detaching from the trigger (TR) and allow the reciprocating link (440) to reciprocate more stably.

[0051] Hereinafter, the operation and operation of an indirect live-line insulating stick (10) according to one embodiment will be described. A user can mount and fix a motor device (PT) in a holder (200) so that the gripping rod (441) of the reciprocating link (440) can grip the trigger (TR). The user can simultaneously grip one side of the body (100) and the grip (320) with one hand, and if necessary, can grip another part of the body (100) with the other hand. When the user grasps the hand gripping the grip (320) and the body (100), the grip (320) rotates to tension the wire (410), the wire (410) rotates the link (430), the link (430) pulls the reciprocating link (440), and the gripping rod (441) of the reciprocating link (440) presses the trigger (TR), thereby operating the motor device (PT). When the user releases the hand that was gripping, the grip (320) returns to its original position, and the gripping rod (441) that pressed the trigger (TR) also returns to its original position, so that the operation of the electric motor (PT) can be stopped.

[0052] FIG. 5 is a schematic side view of an insulating stick for indirect live wire according to one embodiment. The holder (200), lever (300), driving force transmission structure (400), and joint (500) may have the same or similar configuration as described with reference to FIG. 1 to 4. Therefore, the description of the same or similar components will be omitted, and the description will focus on the components that differ.

[0053] In one embodiment, a slot (S) may be formed in at least a portion of the body (100) along the length of the body (100). The slot (S) may be an empty space formed lengthwise inside the body (100), and at least a portion of the wire (410) may be received within the slot (S) and concealed from the outside.

[0054] In one embodiment, a first opening (O1) and a second opening (O2) are formed in the body (100) so that a wire (410) can enter and exit the slot (S). For example, a first opening (O1) is formed on one side of the body (100) adjacent to the holder (200), and a wire (410) extending from the holder (200) toward the lever (300) can be inserted into the slot (S) through the first opening (O1). The wire (410) extends along the slot (S) and can exit the slot (S) through a second opening (O2) formed on one side of the body (100) adjacent to the lever (300). A structure may be formed around the first opening (O1) and the second opening (O2) to prevent compression or damage to the wire (410).

[0055] An indirect live wire insulating stick (10) according to one embodiment can prevent the wire (410) from being damaged by concealing the wire (410) within the body (100), and can prevent the electric motor (PT) from operating differently from the user's intention by the wire (410) coming into contact with an external obstacle.

[0056] Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, suitable results may be achieved even if the described techniques are performed in a different order than described, and / or if the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents.

[0057] Therefore, other implementations, other embodiments, and equivalents to the claims also fall within the scope of the claims set forth below.
