Description

  The present invention relates to a wire support device for an electric fence that is used to prevent harmful animals from invading fields and orchards and to prevent livestock from escaping from the fence of a ranch.

  In general, in order to prevent harmful beasts such as foxes, deer, monkeys, etc. from invading fields and orchards, electric fences are installed along the borders of fields, etc. Is used. It is aimed at the effect that when a pest approaches the electric fence and touches the electric wire, an electric shock is applied, and the electric fence is avoided and cannot be approached. In addition, similar electric fences are used to prevent livestock such as cows and sheep from escaping from the ranch fence.

  The electric wire used in the electric fence is a bare electric wire or a metal wire braided into the fiber. Therefore, when attaching the electric wire to the support, it is necessary to use an insulating mounting device that does not leak. There is. Generally, an electric wire is attached to an insulator made of ceramic, synthetic resin, etc., and a metal fitting such as a bolt is attached to the electric insulator, passed through a through-hole provided in a column, and a nut is screwed to the tip of the metal fitting. A method of fixing together has been proposed. In this method, it is difficult to adjust the height of the insulator, and it may be necessary to make a hole in the support again. Especially in mountainous areas where many electric fences are installed, the insulator should be installed according to the slope of the ground. In many cases, height adjustment was required, and there was a problem in workability.

  Therefore, in order to solve this problem, a semicircular hook portion in which a support column is fitted to one end of the shaft portion is provided and a wing nut is screwed to the other end, and a shaft of the mounting bracket There has been proposed a support device for an electric fence line composed of an insulator inserted through a section.

  This electric fence wire support device can be fitted to the support post by the mounting bracket, so there is no need to drill a fixing hole in the support post, and the wing nut is screwed to press the head of the insulator. The supporting device can be firmly fixed to the support by pressing the bottom of the insulator against the outer peripheral surface of the support while making the support. Furthermore, since the notch part is formed in the bottom part of a lever along the outer peripheral surface of a support | pillar, it is hard to occur that a lever is inadvertently displaced. (For example, refer to Patent Document 1).

Japanese Utility Model Publication No.59-21515

  However, the above-mentioned electric fence line support device has the following problems. That is, the screw portion of the mounting bracket protrudes from the head of the lever, and the wing nut is screwed onto the screw portion. Therefore, when winding the electric fence wire around the lever, the operator mistakenly screwed the electric fence wire. When it is wound around a part or a wing nut, or there is a risk that the screw part or the wing nut may be caught on the operator's hand or clothes, the workability is lowered, which is a problem.

  The present invention is intended to solve the above-described problems and to provide a linear body support device to which a linear body can be easily attached when a linear body is installed between struts.

  In order to achieve the above object, the present invention is configured as follows. That is, the striate erection device according to the present invention is a striate erection device made of a synthetic resin for erection of a striate on a strut that is erected at an appropriate interval, to which the striatum is attached. The lever includes a lever portion, a column mounting portion formed by two opposing holding pieces integrally formed on the lever portion, and a ring member that expands and contracts the interval between the both holding pieces by rotation, and a column between the holding pieces. Is inserted, and both the holding pieces are fastened to the support by rotating the ring member.

  According to the present invention, the insulator portion to which the linear body is attached, the column attachment portion formed of two opposing sandwiching pieces integrally formed with the insulator portion, and the interval between both the sandwiching pieces by expanding and contracting. Since the support is inserted between the holding pieces, there is no need to directly attach a mounting bracket or the like used to fix the support to the support such as a wing nut. When attaching a linear body to a part, a possibility that a linear body and an operator's finger | toe will be caught becomes low, and it can aim at the improvement of workability | operativity.

  In the present invention, the strut mounting portion is formed with a tightening portion formed of two projecting portions having a semicircular cross section projecting from the end portions of both sandwiching pieces, and a ring member is formed on the tightening portion. Is rotatably engaged, and a protrusion is provided on the outer peripheral surface of the tightening portion, and an upper end portion of the protrusion is slidably contacted with a concave surface provided on the inner peripheral surface of the ring member. If the concave surface is gradually shallower along the rotating direction of the ring member, the concave member is clamped by a relatively slight rotational operation of the ring member by appropriately setting the depth of the concave portion. Since the distance between the pieces can be easily expanded or reduced, there is no need to rotate multiple times as in the case of using screws, bolts, nuts, etc. Adjustment is easier.

  Further, in the present invention, when the convex surface is formed in the direction perpendicular to the rotation direction of the ring member, the concave surface of the ring member is rotated by rotating the ring member to narrow the gap between the sandwiching pieces. When fixing, the protrusion of the groove part is difficult to reverse when it exceeds the ridge, so the clamping force of both clamping pieces against the column decreases, and the clamping position by the clamping piece shifts downward or inadvertently Problems such as sliding down are less likely to occur.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  That is, FIG. 1 is an explanatory view showing an embodiment of a linear body erection device according to the present invention, FIG. 2 is a front view showing an embodiment of the use state of the linear body erection device according to the present invention, and FIG. 1 is an enlarged view of a main part of FIG. 1, FIG. 4 is a partially exploded side view of FIG. 3, FIG. 5 is an explanatory view of a ring member, FIG. 6 is an enlarged cross-sectional explanatory view of FIG. It is explanatory drawing of a member.

  In the drawings, reference numeral 1 denotes a lever part to which the linear member C is attached, 2 denotes a column attachment part 2 composed of two clamping pieces 4 for fastening the column 3, and 5 denotes a ring for expanding and contracting the interval between the two clamping pieces 4. It is a member. The linear body erection device P according to the present embodiment is mainly composed of the insulator part 1, the column attachment part 2, and the ring member 5, and the linear object C is attached to the insulator part 1.

  The striated body C is generally made of only a metallic striated body or a material obtained by knitting a synthetic resin striated body as appropriate, and surrounds fields such as fields and orchards. In addition to preventing the infestation of beasts, traps, deer, monkeys, and other harmful beasts, they are energized to give an electric shock to the contacted beasts. As the metal wire rod, there is an aluminum alloy wire rod which is not easily corroded even when installed outdoors, is flexible enough to be wound around the insulator 1 and the like, and has a strength enough to be installed between the columns. Although used suitably, other metals, for example, a steel wire, a stainless steel wire, a copper wire, etc. may be used. In addition, polyethylene, polyester, polyamide, polyaramid, or the like can be suitably used as the linear body made of synthetic resin. In addition, the linear body C may consist only of a synthetic resin linear body, when it is not necessary to supply with electricity.

  The support 3 shown in FIG. 1 is generally a steel pipe coated with a synthetic resin, is relatively lightweight and excellent in strength, and is coated with a synthetic resin to improve corrosion resistance and durability, and at the outer periphery. Therefore, it is preferably used because it is difficult to energize. In addition, it is not restricted to this form, The support | pillar made from a timber or a synthetic resin may be sufficient, the linear body construction apparatus P can be attached, and the linear body C is attached to the insulator part 1, and a support | pillar 3 has a sufficient strength to lay the filament C between 3 can be used as appropriate.

  A cap member 31 is attached to the upper end of the column 3 as shown in FIG. 7A and 7B are explanatory views of the cap member 31, wherein FIG. 7A is a front view, FIG. 7B is a side view, and FIG. 7C is a DD cross-sectional view of FIG. The cap member 31 is formed in a substantially cylindrical shape, and includes a hole portion 32 into which the upper end of the support column 3 is inserted, a lower attachment portion 33 to which the filament C is attached, and an upper attachment portion 34. The hole portion 32 is formed at the lower portion of the cap member 31 and is opened downward, and has a projecting portion having a cross-sectional cross shape from the bottom portion of the hole portion 32 toward the entrance / exit. The support column 3 is inserted between the inner wall surface of the hole 32 and the side end portion of the protruding portion so that the upper end portion is covered and rainwater or the like does not enter inside.

  The lower mounting portion 33 is provided in the upper portion of the hole portion 32 and includes guide grooves 35 that are inserted left and right from the front side toward the inner side, and extends in the vertical direction at the inner portion of the guide groove 35. A stepped portion 35 is formed. As a result, if the filament C is inserted in the left-right direction at the back through the guide groove 35, it is difficult for the step C 36 to come out to the front side.

  The form of the guide groove 35 is not particularly limited. However, if the guide groove 35 is formed in an inverted V shape when viewed from the front as in the present embodiment, the linear body inserted in the left-right direction at the back of the guide groove 35. C becomes more difficult to escape to the front side. Moreover, the top part of the lower wall part of the guide groove 35 is made higher than the line which connects the both ends of an upper wall part, and the linear body C becomes difficult to come out more. It should be noted that the guide groove 35 can have the same effect even if it is formed in a V shape or an arc shape when viewed from the front. In addition, the side wall portion below the guide groove 35 is formed with a slope 36 that is cut obliquely downward from the back to the front side. This makes it easier for the operator to insert the linear body C from the front side of the guide groove 35 into the back part.

  The upper mounting portion 34 is provided at the head of the cap member 31, and a groove portion 37 having a U-shaped longitudinal section is formed downward from the upper end portion, and the lower portion is reduced in diameter. With this structure, when the linear body C is wound around the reduced diameter portion 38, if the linear body C is appropriately inserted into the groove portion 37, the wound linear body C becomes more difficult to slip. In addition, when it is not necessary to attach the linear body C, the cap member 31 may have a form without the lower mounting portion 33 and the upper mounting portion 34.

  Next, the striatum erection device P according to this embodiment will be described. FIG. 1 shows a striated body erection device P according to the present embodiment, wherein (a) is a front view and (b) is a side view. The linear body erection device P includes an insulator part 1 to which the linear body C is attached, and a post attachment part 2, and a support post 3 is inserted between the sandwiching pieces 4 of the post attachment part 2, and a support attachment part. By rotating the ring member 5 to the end of 2, the holding pieces 4 can be fastened to the support column 3, and can be fixed to any position of the support column 3.

  The wire body erection device P will be described in more detail. FIGS. 3A and 3B are enlarged views of the striated body erection device P shown in FIG. 1, wherein FIG. 3A is a front view and FIG. 3B is a cross-sectional view taken along line AA in FIG. First, the insulator portion 1 includes a shaft portion 11 to which the linear body C is attached, and two disk members 12 provided along the outer peripheral portion of the shaft portion 11. Further, on the head side of the insulator portion 1, the shaft portion 11 and the outer surface of the disk portion 12 are substantially flush with each other. Accordingly, as shown in FIG. 2, when the linear body C is wound around the shaft portion 11 and attached to the insulator portion 1, the operator generally attaches the linear body C on the head side of the insulator portion 1. Therefore, the operator's hand and clothes are not caught on the outer surface of the insulator 1, and the filament C is easily wound around the shaft portion 11 between the disk portions 12.

  Further, a notch disk member 13 having a notch groove 14 formed from the outer peripheral surface toward the center is provided between the two disk portions 12. With this structure, the linear body C is wound between one disk part 12 and the notch disk part 13, and then wound between the other disk part 12 and the notch disk part 13 through the notch groove 14. The striatum C is less likely to loosen.

  Next, FIG. 4 is a partially exploded explanatory view in which the ring member 5 is removed in the striated body construction device P, (a) is a top view, and (b) is a column attachment viewed from the arrow side of (a). 3 is a front view of part 2. FIG. The column attachment part 2 is composed of two opposing sandwiching pieces 4 formed integrally from the bottom of the insulator part 1, and the sandwiching piece 4 is formed in an arc shape along the outer peripheral surface of the pillar 3. The inner diameter is substantially the same as the outer diameter of the column 3. Further, the two clamping pieces 4 are provided with tightening portions 6 composed of two projecting portions 61 that project from the end portions thereof in opposition to each other. The outer peripheral surfaces 62 of the protrusions 61 are each formed in an arc shape in the longitudinal section, the inner wall surface 63 is formed in a semicircular shape in cross section formed in a substantially planar shape, and the opposing inner wall surfaces 63 are spaced apart from each other. Is provided. That is, the tightening portion 6 has a shape in which the outer peripheral surface is formed in a circular cross section by the outer peripheral surfaces 62 of the two protruding portions 61 and the central portion thereof is spaced in the vertical direction.

  5A and 5B are explanatory views of the ring member 5, wherein FIG. 5A is a plan view seen from the head side, FIG. 5B is a plan view seen from the bottom side, and FIG. 5C is a cross-sectional view taken along the line CC in FIG. It is. The ring member 5 has the same thickness as the protruding length of the tightening portion 6, and the inner diameter of the hole 51 formed in the thickness direction is the same as the outer diameter of the outer peripheral surface of the tightening portion 6. It is about. Thereby, the ring member 5 can be arrange | positioned so that rotation along the outer peripheral surface of the clamping part 6 is possible. A handle protrudes from the outer peripheral surface of the ring member 5. In this embodiment, the handle is provided at a position opposite to the outer peripheral surface, but any handle may be provided as long as the operator can easily rotate the ring member 5.

  Next, how the ring member 5 is engaged with the tightening portion 6 will be described. As shown in FIG. 4, a locking protrusion 64 is formed in the circumferential direction of the outer peripheral surface 62 at the head of the protrusion 61, and the outer diameter of the locking protrusion 64 is the hole 51 of the ring member 5. It is made larger than the inner diameter. Further, locking protrusions 65 protrude from the outer peripheral surface of the locking protrusion 64 so as to face each other. As a result, the ring member 5 is not easily pulled out of the container tightening portion 6 by the locking protrusion 64 and the locking protrusion 65. In this embodiment, as shown in FIGS. 6A and 6C, the hole 51 of the ring member 5 is notched in the circumferential direction from the head to the bottom, and the outer diameter is locked. A step portion 52 that is larger than the distance between the protrusions 65 is formed. Accordingly, the locking protrusion 64 does not protrude from the head side of the hole 51 and can be disposed inside the hole 51, and is easy to grip when the operator rotates the ring member 5. Further, it becomes difficult for fingers or the like to be caught in the gap between the protruding portions 61, and workability can be improved.

  Next, a mechanism for expanding and reducing the gap between the sandwiching pieces 4 will be described. Specifically, a mechanism for expanding and contracting the interval between the two projecting portions 61 facing each other in the tightening portion 6 of the clamping piece 4 will be described.

  As shown in FIGS. 4 and 6, the outer peripheral surface 62 of the tightening portion 6 includes protrusions 66 that are formed to face each other from the proximal end toward the distal end. Further, as shown in FIGS. 5 and 6, the ring member 5 is formed with a recessed surface 53 provided on the inner wall surface of the hole 51 from the bottom toward the head. When the ring member 5 is rotated in the circumferential direction, the upper end portion 67 of the protrusion 66 is slidably contacted with the recessed surface 53, and the opposed recessed surfaces 53 are opposed to the ring member 5. It gradually becomes shallower relative to each other along the rotation direction.

  With this structure, when the ring member 5 is rotated with respect to the protrusion 66 in the direction in which the recessed surface 53 becomes shallower from the state shown in FIG. 6A, the ring as shown in FIG. The member 5 presses the two protrusions 61 of the tightening portion 6 inward through the protrusions 66 that are in contact with the concave surface 53, and the interval between the two protrusions 61 is narrowed. That is, since the interval between the protrusions 61 can be expanded and contracted by rotating the ring member 5, the interval between the sandwiching pieces 4 can also be expanded and contracted. As shown in FIG. 1, the columns 3 are interposed between the sandwiching pieces 4. In the inserted state, the sandwiching piece 4 can be disposed at an arbitrary position of the support column 3, and the support column 3 can be fastened and fixed at the position. Further, when tightening with a wing nut or the like, generally, since it is rotated a plurality of times, it has been necessary to change the position each time. However, in this embodiment, the tightening operation can be performed within a range in which the ring member 5 is rotated halfway. Since the ring member 5 does not need to be changed, workability is improved.

  The concave surface 53 includes a ridge 54 formed in a direction perpendicular to the rotational direction of the ring member 5. As a result, when the ring member 5 is rotated with respect to the protrusion 66 in the direction in which the recessed surface 53 becomes shallower, if the protrusion 66 exceeds the protrusion 54, the protrusion 66 is inadvertently reversed by the protrusion 54. The clamping piece 4 is less likely to rotate and the clamping force of the clamping piece 4 to the support column 3 is less likely to decrease, and the clamping piece 4 is less likely to be displaced relative to the support column 3.

  The number of ridges 54 may be one, but if a plurality of ridges 54 are formed as in the present embodiment, the ring member 5 can be held until the holding piece 4 sufficiently tightens the support post 3 even if an error in the outer diameter of the support post 3 occurs. If it is rotated, the ring member 5 is less likely to rotate in the reverse direction due to the protrusion 54 that the protrusion 66 has finally exceeded, and the sandwiching piece 4 is less likely to be displaced with respect to the column 3.

  The formation position of the protrusion 66 is not particularly limited, but is formed on the top of the outer peripheral surface 62 of the tightening portion 6 in this embodiment. Accordingly, when the ring member 5 is rotated, the interval between the protrusions 61 can be effectively expanded or reduced. The number of the protrusions 66 may be one, but two is preferable because the interval between the protrusions 61 can be more effectively narrowed. That is, since the amount of rotation of the ring member 5 can be reduced, the work can be performed more efficiently.

  Next, in the clamping piece 4 of the support | pillar attaching part 2, the form of an arc-shaped part is demonstrated in detail. In this embodiment, as shown in FIG. 4, the sandwiching piece 4 is composed of a sandwiching piece 4a having a center angle α of the arcuate portion and a sandwiching piece 4b having a center angle β of the arcuate portion, and the angle is 90 °. <Α <180 ° <β <270 °. The sandwiching piece 4a has a substantially uniform thickness, but the sandwiching piece 4b includes a thin portion 41 having a recessed outer peripheral surface. Thus, when the ring member 5 is rotated to narrow the interval between the sandwiching pieces 4a and 4b and the support column 3 is tightened, the thin portion of the sandwiching piece 4b is mainly elastically deformed, and the sandwiching piece 4a is hardly elastically deformed. That is, the outer peripheral surface of the support column 3 is substantially abutted along the inner wall surface of the sandwiching piece 4a and is pressed and tightened from the opposite portion by the sandwiching piece 4b, and the sandwiching piece 4 has the same length. Compared to the above, the sandwiching pieces 4a and 4b have a large contact area with the outer peripheral surface of the support column 3, and the support column 3 can be tightened more firmly to prevent slipping.

  Moreover, as shown in FIG. 10, you may provide the protrusion 42 along the up-down direction in the internal peripheral surface of the clamping piece 4. As shown in FIG. Thereby, a support | pillar (not shown) can be clamp | tightened more firmly and it can be made hard to slip. The position of the protrusion 42 is not particularly limited as long as it is the inner peripheral surface of the sandwiching piece 4, but in this embodiment, the end of the sandwiching piece 4 has a tapered shape, and the protrusion 42 is provided at this position. When the column is tightened, the protrusion 42 can be formed in a relatively large shape without unnecessarily protruding, and the protrusion 42 is not easily crushed and the column can be tightened more firmly.

  Also, with this structure, as shown in FIG. 3 (b), when the insulator part 1 is disposed in the front, the ring member 5 is positioned in the diagonally rearward direction, so that the filament C is attached to the insulator part 1. At this time, it is difficult for the linear member C to be caught by the ring member 5, and the mounting operation becomes easier. Further, the rotation operation is relatively easy as compared with the case where the ring member 5 is located directly behind, which is more preferable. And if the linear body attachment apparatus P is reversed right and left, it will become possible to position the ring member 5 in the side which is easy to work | work according to an operator's dominant hand.

  FIGS. 8-9 is a perspective view which shows the 2nd form of implementation of the linear body construction apparatus based on this invention. The striate erection device according to the second embodiment is different from the striatum erection device shown in FIG. 3 in that the notch disk portion 13 of the insulator portion 1 is extended in the vertical direction. Is similar to that shown in FIG.

  That is, FIG. 9 is a partially enlarged view of the striated body erection device according to the present embodiment, (a) is an enlarged front view of the lever part 1, and (b) is an enlarged plan view of the lever part 1. As shown in (b), the notch disk part 13 of the insulator part 1 has an elliptical shape extended in the vertical direction, and the vertical dimension is made longer than the disk parts 12 and 12 on both sides. . In general, when the filament C is wound around the insulator portion 1, as shown in FIG. 2, a plurality of support columns 3 to which the filament constructing device P is attached at appropriate intervals are erected, and the filament C is attached to one end. When winding in order from the column side, as shown in FIG. 8 (a), first, both ends of the wire C are fixed and installed, and then the wire C is cut out as shown in FIG. 8 (b). There is a case where it is hooked and attached to the notch groove 14 of the portion 13. In the latter case, since the striated body C is stretched, if the notched disk part 13 is longer in the vertical direction than the disk parts 12 on both sides as in this embodiment, the striated body C Further, the deeper the notch groove 14 is, the more easily the hooked wire C is less likely to come off, which is preferable.

  The insulator part 1, the clamping piece 2 formed integrally with the insulator part 1, and the ring member 5 are made from a synthetic resin such as polyethylene, polypropylene, ABS resin, polycarbonate, polyamide, polystyrene, polyacetal, It can be used appropriately according to the required weather resistance, strength, elasticity and the like.

  According to the present invention, since the striatum support device can easily attach the striatum when installing the striatum between the columns, the striatum is placed around fields, orchards, and the like. When attaching, especially when the installation length extends over a long distance, or when the number of attached striates is large, it can be suitably used. Moreover, since the installation height with respect to the support can be easily adjusted, it can be suitably used even when the installation place such as an inclined place is not horizontal.
