Technology Field

[0001] The present invention relates to a wire separation stick that maintains a wire and a facility supported on a utility pole at a distance greater than a safe distance. Background Technology

[0003] Urban pedestrian walkways and roadways are intermingled with a large number of utility poles supporting power lines, as well as various facilities such as streetlights and traffic lights. Consequently, it is frequently observed that a sufficient safety distance to prevent electric shock accidents is not maintained between power lines and facilities.

[0004] Furthermore, although power lines or facilities are installed to ensure a safe distance between them, there may be instances where the lines sway or sag due to disturbances or gravity, resulting in a failure to maintain this safety distance. Consequently, there is a high risk of safety accidents, such as electric shock, for workers installing or repairing facilities or for pedestrians, making it necessary to implement measures to prevent such incidents.

[0010] The above spacing maintaining part may include a variable load part capable of changing the length.

[0011] The above spacing maintaining member may further include an angle adjustment member that connects the variable load member and the support fixing member and can change the angle between the variable load member and the support fixing member.

[0012] Even if the angle between the variable load part and the support fixing part is changed by the angle adjustment part, the height of the wire gripping part may not change.

[0013] The above-mentioned support fixing part can surround the support and be fixed in close contact with the support.

[0014] The above-mentioned wire gripping member may include a pair of finger members capable of changing positions between a position in which the wire is closed to confine the wire and a position in which the wire is spread out to allow it to escape. Effects of the invention

Specific details for implementing the invention

[0019] Hereinafter, a wire separation stick according to an embodiment of the present invention will be described in detail with reference to the attached drawings. The terminology used in this specification is used to appropriately express preferred embodiments of the present invention, and may vary depending on the intent of the user or operator or the conventions of the field to which the present invention belongs. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0020] FIG. 1 is a perspective view of a wire spacing stick according to one embodiment of the present invention, FIG. 2 is a cross-sectional view of the support fixing part of FIG. 1, FIG. 3 is a cross-sectional view of the angle adjustment part of FIG. 1, FIG. 4 is a cross-sectional view of the variable rod part of FIG. 1, FIG. 5 is a cross-sectional view of the wire gripping part of FIG. 1, and FIG. 6 is a schematic perspective view illustrating the wire spacing stick according to one embodiment of the present invention installed on a street light.

[0021] Referring to FIGS. 1 to 5, a wire spacing stick (20) according to one embodiment of the present invention includes a wire gripping portion (100), a support fixing portion (21), and a spacing maintaining portion (50). The wire gripping portion (100) grips the wire (9) so that it does not detach. The support fixing portion (21) is fixedly coupled to a support (6), such as a street light, for example. One side of the spacing maintaining portion (50) is coupled to the wire gripping portion (100), and the other side is coupled to the support fixing portion (21).

[0022] The support fixing part (21) can surround the support (6) and be fixed in close contact with the support (6). The support fixing part (21) may include first and second braces (22, 30) made of metal material. The first and second braces (22, 30) may each include a semicircular portion extended in a semicircular shape and a pair of fastening portions (24, 35) at both ends of the semicircular portion.

[0023] By holding the first and second braces (22, 30) so that the semicircular portions of the first and second braces (22, 30) wrap around the column of the support (6) and the fastening portions (24, 35) of the first and second braces (22, 30) face each other, and fastening the facing fastening portions (24, 35) with a bolt (40) and a nut (43), the support fixing portion (21) can be fixedly installed on the support (6).

[0024] When a pair of bolts (40) are each strongly tightened to their corresponding nuts (43), the support fixing part (21) can be firmly fixed to the support (6). Meanwhile, the support fixing part (21) shown in FIG. 2 is exemplary, and the wire spacing stick of the present invention may include other types of support fixing parts.

[0025] The spacing maintenance part (50) may include an angle adjustment part (51) and a variable load part (80). The angle adjustment part (51) may connect the support fixing part (21) and the variable load part (80). The angle adjustment part (51) may change the angle between the variable load part (80) and the support fixing part (21).

[0026] The angle adjustment part (51) may include a support fixing part assembly (53), a first hinge cap member (60), and a second hinge cap member (70). The support fixing part assembly (53) may include a bracket part (54) and a tube part (57). The bracket part (54) may be coupled to one side of the support fixing part (21).

[0027] Specifically, the bracket portion (54) can be detachably connected to the variable rod portion coupling portion (31) provided at the center of the semicircular portion of the second brace (30) by means of a bolt (45) and a nut (48) fastened thereto. The tubular portion (57) is a tubular part connected to the bracket portion (54) and extending outward in a direction protruding from the outer surface of the support fixing portion (21).

[0028] The front end of the tube portion (57) may be open. The tube portion (57) may be formed integrally with the bracket portion (54). However, unlike what is shown in FIG. 3, the tube portion (57) may be detachably connected to the bracket portion (54). The support fixing portion assembly (53) may be formed from, for example, a metal material or a plastic material.

[0029] The first hinge cap member (60) may include a first insertion projection (61) and a pair of spaced projections (65). The first insertion projection (61) may be inserted inwardly from the front end of the tube portion (57) to close the open front end of the tube portion (57). The outer surface of the first insertion projection (61) may be in contact with the inner surface of the tube portion (57).

[0030] The outer surface of the first insertion projection (61) can be pressed against the ends of a plurality of tightening bolts (78) that penetrate the tube (57). Accordingly, the first hinge cap member (60) can be fixed to the support fixing assembly (53).

[0031] After loosening the tightening of the multiple tightening bolts (78) and rotating the first insertion projection (61) by a certain angle around the first longitudinal axis (LX1) extended in the longitudinal direction of the pipe (57), the multiple tightening bolts (78) are tightened again, so that the first hinge cap member (60) can be fixed by changing the angle around the first longitudinal axis (LX1).

[0032] A pair of spaced-out protrusions (65) may be spaced apart from each other and extend in the opposite direction to the direction in which the first insertion protrusion (61) protrudes. A through hole may be formed in each spaced-out protrusion (65) through which an angle adjustment bolt (80) passes.

[0033] The first hinge cap member (60) may further include a flange portion (63) that is steppedly extended in the radial direction of the first longitudinal axis (LX1) between the first insertion projection (61) and a pair of spaced projections (65). Since the flange portion (63) is blocked at the front end of the pipe portion (57), the first hinge cap member (60) may not be excessively inserted into the pipe portion (57).

[0034] The second hinge cap member (70) may include a second insertion projection (71) and an intermediate projection (75). The second insertion projection (71) may protrude toward the variable rod portion (80). A male screw pattern may be formed on the outer surface (72) of the second insertion projection (71).

[0035] The intermediate projection (75) extends in the opposite direction to the direction in which the second insertion projection (71) protrudes and may be interposed between a pair of spaced projections (65). A through hole through which an angle adjustment bolt (80) passes may be formed in the intermediate projection (75).

[0036] By aligning the pair of through holes of the pair of spaced protrusions (65) and the through hole of the middle protrusion (75) along the height axis (HX) that extends vertically and intersects the first longitudinal axis (LX1), and passing an angle adjustment bolt (80) through them, and fastening an angle adjustment nut (85) to the end of the angle adjustment bolt (80), the second hinge cap member (70) can be rotatably coupled to the first hinge cap member (60) around the height axis (HX).

[0037] When the angle between the first hinge cap member (60) and the second hinge cap member (70) is adjusted to a desired angle and the angle adjustment bolt (80) is tightened against the angle adjustment nut (85), a pair of spaced protrusions (65) are brought into close contact with both sides of the middle protrusion (75), so that the angle between the first hinge cap member (60) and the first hinge cap member (70) can be fixed.

[0038] If a pattern that increases friction, such as a sawtooth pattern, is formed on the side facing the middle protrusion (75) and a pair of spacing protrusions (65), the angle between the first hinge cap member (60) and the second hinge cap member (70) may not change even if an unintended external force is applied. Meanwhile, the angle adjustment part (51) shown in FIG. 3 is exemplary, and the wire spacing stick of the present invention may include an angle adjustment part of a different type.

[0039] The variable rod section (80) may include a tubular first rod (81) and a second rod (90) that extend along the second longitudinal axis (LX2) and partially overlap. The angle between the first longitudinal axis (LX1) and the second longitudinal axis (LX2) may be the same as the angle adjusted by the angle adjustment section (51). The first longitudinal axis (LX1) and the second longitudinal axis (LX2) may each be orthogonal to the height axis (HX).

[0040] The second insertion projection (71) can be inserted inward from one end of the first rod (81) to close the open one end of the first rod (81). On the inner surface (83) of one end of the first rod (81), a female screw pattern that engages with the male screw pattern formed on the outer surface (72) of the second insertion projection (71) can be formed. Accordingly, the second hinge cap member (70) can be fastened and fixed to the first rod (81).

[0041] The second hinge cap member (70) may further include a flange portion (73) that is steppedly extended in the radial direction of the second longitudinal axis (LX2) between the second insertion projection (71) and the intermediate projection (75). Since the flange portion (73) is blocked at one end of the first rod (81), the second hinge cap member (70) may not be excessively inserted into the first rod (81).

[0042] One end of the second rod (90) can be inserted into the inner side of the other end of the first rod (81). A plurality of protruding through holes (85, 86, 87) spaced apart along a straight line parallel to the second longitudinal axis (LX2) may be formed on the side wall of the other end of the first rod (90). The second rod (90) may include a length adjustment projection (92) that protrudes radially through the side wall to be fitted into one of the plurality of protruding through holes (85, 86, 87) at one end.

[0043] A projection protrusion through hole (91) through which a length adjustment projection (92) passes may be formed in the side wall of the second rod (90). The outer end portion of the length adjustment projection (92) may have a curved, convex shape. The length adjustment projection (92) may include a projection flange (93) with a stepped diameter expanded at the inner end portion.

[0044] The inner diameter of the projection protrusion through hole (91) may be smaller than the diameter of the projection flange (93). Accordingly, the outer end portion of the projection protrusion through hole (91) may protrude to the outside of the first rod (81) and the second rod (90) through the projection protrusion through hole (91) and the projection through hole (85, 86, 87), but the projection protrusion through hole (91) may not detach from the second rod (90).

[0045] The protruding through hole (91) can be elastically biased to protrude outward from the side wall of the second rod (90) by a spring (97). The spring (97) may be, for example, a coil spring. One end of the spring (97) that is relatively close to the second longitudinal axis (LX2) may be supported by a spring support bracket (95). The spring support bracket (95) may be coupled and supported on the inner side of the side wall of the second rod (90). The other end of the spring (97) that is relatively far from the second longitudinal axis (LX2) may be supported by a protruding flange (93).

[0046] With one end of the second rod (90) inserted into the other end of the first rod (81), a plurality of protrusion through holes (85, 86, 87) and a length adjustment protrusion (92) are aligned in a straight line parallel to the second longitudinal axis (LX2), and when the second rod (90) is inserted into the first rod (81) in a direction where the other end of the second rod (90) approaches the other end of the first rod (81), the length adjustment protrusion (92) is fitted into the third protrusion through hole (87) closest to the other end of the first rod (81) among the plurality of protrusion through holes (85, 86, 87) and can protrude outward from the side wall of the first rod (81). Accordingly, the first rod (81) and the second rod (90) can be combined.

[0047] When a worker presses the length adjustment projection (92) inward toward the second longitudinal axis (LX2) and inserts the second rod (90) into the first rod (81) in a direction such that the other end of the second rod (90) is closer to the other end of the first rod (81), the length adjustment projection (92) can be fitted into the second projection through hole (86) located in the middle among the plurality of projection through holes (85, 86, 87) and protrude outward from the side wall of the first rod (81). In this case, the length of the variable rod portion (80) can be shorter than when the length adjustment projection (92) is fitted into the third projection through hole (87). Here, the length of the variable rod portion (80) may refer to the distance from one end of the first rod (81) to the other end of the second rod (90).

[0048] When the operator presses the length adjustment projection (92) inward again toward the second longitudinal axis (LX2) and inserts the second rod (90) into the first rod (81) in a direction such that the other end of the second rod (90) is closer to the other end of the first rod (81), the length adjustment projection (92) can be fitted into the first projection through hole (85) furthest from the other end of the first rod (81) among the plurality of projection through holes (85, 86, 87) and protrude outward from the side wall of the first rod (81). In this case, the length of the variable rod portion (80) can be shortened compared to when the length adjustment projection (92) is fitted into the second projection through hole (86).

[0049] In this way, the operator can change the length of the variable rod portion (80) by changing the protrusion through-hole (85, 86, 87) into which the length adjustment protrusion (92) is inserted. Meanwhile, the variable rod portion (80) shown in FIG. 4 is exemplary, and the wire spacing stick of the present invention may include other types of variable rod portions.

[0050] The wire gripping portion (100) may include first and second finger members (101, 110) capable of changing positions between a position that is closed to confine the wire (9) and a position that is spread open to allow the wire (9) to escape, and a screw (120).

[0051] The first finger member (101) may include a base (105), an insertion projection (108), and a first finger (103). A slider guide groove (106) may be formed in the base (105) in a direction intersecting the second longitudinal axis (LX2). The insertion projection (108) may be inserted inward from the other end of the second rod (90) to close the open other end of the second rod (90). The outer surface of the insertion projection (108) may contact the inner surface of the second rod (90).

[0052] The outer surface of the insertion projection (108) can be pressed against the ends of a plurality of tightening bolts (128) that penetrate the second rod (90). Accordingly, the first finger member (101) can be fixed to the second rod (90).

[0053] By loosening the tightening of the multiple tightening bolts (128) and rotating the insertion projection (108) by a certain angle around the second longitudinal axis (LX2) extended in the longitudinal direction of the second rod (90), and then tightening the multiple tightening bolts (128) again, the wire gripping portion (100) can be fixed by changing the angle around the second longitudinal axis (LX2). The first finger (103) can be extended in the opposite direction to the direction in which the insertion projection (108) protrudes.

[0054] The second finger member (110) may include a slider (115) and a second finger (113). The slider (115) may be extended in a direction intersecting the second longitudinal axis (LX2) so as to be inserted into the slider guide groove (106). The second finger (113) may be extended in the opposite direction to the direction in which the insertion projection (108) is extended.

[0055] When the end (104) of the first finger (103) and the end (114) of the second finger (113) come into contact, a space can be formed that is closed by the first finger (103), the second finger (113), and the base (105) to confine the wire (9) so that it cannot escape. This case is the closed position of the first and second fingers (103, 113) shown by solid lines in FIG. 5.

[0056] When the end (104) of the second finger (103) and the end (114) of the second finger (113) are separated, the wire (9) can enter the interior of the wire gripping part (100), that is, between the first and second fingers (103, 113) and the base (105), or be removed from the wire gripping part (100) through the space between the separated pair of ends (104, 114). This case is when the first and second fingers (103, 113) are in a spread position. When in the spread position, the second finger (113) is shown as a dotted line in FIG. 5.

[0057] The screw (120) can connect the first finger (103) and the second finger (113) so that the second finger (113) is closed or opened relative to the first finger (103). Specifically, the screw (120) may include a screw body (123) that extends through the slider (115) and a screw head (121) that is connected to one end of the screw body (123) and protrudes outward from the second finger member (110).

[0058] The other end portion (125) of the screw body (123) can be rotatably coupled to the base (105) of the first finger member (101). The screw body (123) extends in a direction intersecting the second longitudinal axis (LX2), and a male screw pattern can be formed on its outer surface. A screw body through hole (116) through which the screw body (123) passes is formed in the slider (115), and a female screw pattern that engages with the male screw pattern of the screw body (123) can be formed on the inner surface of the screw body through hole (116).

[0059] With this configuration, when a worker uses a tool to rotate the screw head (121) and the screw body (123) connected thereto in one direction relative to the first and second finger members (101, 110), the second finger member (110) moves in a direction approaching the first finger member (101), so that the end (104) of the first finger (103) and the end (114) of the second finger (113) can come into contact. In other words, the first and second fingers (103, 113) can be closed.

[0060] Conversely, if a worker uses a tool to rotate the screw head (121) and the screw body (123) connected thereto with respect to the first and second finger members (101, 110) in the other direction, that is, in the opposite direction to one direction, the second finger member (110) moves away from the first finger member (101), so that the end (104) of the first finger (103) and the end (114) of the second finger (113) can be separated. In other words, the first and second fingers (103, 113) can be spread apart. Meanwhile, the wire gripping part (100) illustrated in FIG. 5 is exemplary, and the wire separation stick of the present invention may include other types of wire gripping parts.

[0061] Referring to FIGS. 1 and FIGS. 6, a wire spacing stick (20) according to one embodiment of the present invention can be fixedly installed on a column (7) of an outdoor facility, such as a street light (6). Accordingly, an outdoor facility such as a street light (6) can be referred to as a support.

[0062] In the wire gripping portion (100) of the wire spacing stick (20), a portion of a wire (9) can be gripped, with both ends supported by a pair of poles (2, 4) adjacent to a street light, i.e., a support (6). The portion of the wire (9) gripped in the wire gripping portion (100) does not shake or sag despite external disturbances or the influence of gravity, and the distance between the support (6) and the wire (9) can be maintained at a distance greater than the safety distance determined by laws or regulations by the spacing maintenance portion (50).

[0063] The wire separation stick (20) described above maintains a distance greater than the safety distance between the wire (9) and the outdoor facility (6). Therefore, it is possible to prevent safety accidents such as electric shock that may occur to workers or pedestrians installing or repairing the facility (6).

[0064] The present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true scope of protection of the present invention should be determined by the appended claims. Explanation of the symbols
