【Example】

 Hereinafter, an embodiment of a marker locking device according to the present invention will be described with reference to the drawings. 1 and 2 are a front view and a side view of a marker fastener 1 of the present invention, which is made of a metal plate having a thickness of 6 mm, a width of 30 mm, and a length of 85 mm, and a 10φ rope mounting hole 2 at the center upper end. Is formed, and a wire rope locking hole 3 consisting of an opening 3a having a width of 16.1 mm and a round hole 3b having a half diameter of 9 mm which communicates with the opening 3a is formed substantially in the middle of the length direction, and the lower end A curved groove 4 having a radius of 40 mm and a width of 4.5 mm is formed on the inner side of the groove, and further, an inclined straight line having a width of 4.5 mm is formed at an intermediate position between the curved groove 4 and the wire rope locking hole 3. The groove 5 is formed.

Here, when attaching to a guard rope as shown in FIG. 7, since the wire rope 6 which constitutes this guard rope is a twisted wire, the minimum diameter X and the maximum diameter are directly attached to the wire rope 6. Y and Y occur. Therefore, the width of the opening 3a in the wire rope locking hole 3 is set to 16.1 mm which is slightly larger than the minimum diameter X, and the diameter of the round hole 3b is slightly larger than the maximum diameter Y. It is 9 mm.

In the case of a flat guardrail 7 as shown in FIG. 4, the width of the linear groove 5 is set to 4.5 mm, which is slightly larger than the thickness of the guardrail 7, and the wire extends from the opening. In the case of a linear groove shape inclined toward the rope locking hole 3 and, further, in the case of the corrugated plate-shaped guard rail 8 as shown in FIG. 5, the width of the corrugated plate-shaped groove 4 is set to the thickness of the guard rail 8. It has a slightly larger size of 4.5 mm and is formed in a curved groove shape in a horizontal state.

Next, a method of using the marker locking tool 1 having the above-described configuration will be described with reference to FIGS. 3 to 6. In FIG. 3, 9 is a sign for road construction or the like, 10 is a support rod for supporting the sign 9, and 11 is the support rod 10 attached to a guard rail (in this embodiment, a flat guard rail 7 is shown). An attachment metal fitting 12 is a rope whose one end is fixed to the upper end of the support rod 10. Then, the other end of the rope 12 is attached to the attachment hole 2 of the marker locking device 1 according to the present invention via a fastener 13.

Since the locking tool 1 in this embodiment is the flat guard rail 7, the linear groove 5 is inserted into the upper edge of the guard rail 7 as shown in FIG. At this time, since the width of the linear groove 5 is slightly larger than the thickness of the guardrail 7, it can be inserted. Then, in this inserted state, while pulling the rope 12, the locking tool 1 is moved along the guardrail 7 and pulled until the rope 12 is tensioned and released, the locking tool 1 is tensioned by the rope 12. Tilt by force.

In this inclined state, the opposite edges of the linear groove 5 are pressed against the guardrail 7, so that the locking tool 1 is fixed to the guardrail 7, and therefore the support rod 10 is fixed. By sandwiching the rope 12 and the locking tool 1 in the same manner on the other side, by tensioning the rope 12, the upper end of the support rod 10 is pulled by the rope 12 from the direction of 180 degrees and stands up. It is fixed.

FIG. 5 shows a case of a corrugated plate-shaped guard rail 8. In this case as well, the curved groove 4 is inserted into the upper edge of the guard rail 8 and the rope 12 is pulled from both ends in the same manner as described above. The support rod 10 can be fixed in the upright state.

FIG. 6 shows a case of a guard rope in which a plurality of wires are twisted, and as described above, from the minimum diameter portion of the wire rope 6 to the opening 3 a of the wire rope locking hole 3 in the locking tool 1. When the wire rope 6 is inserted into the round hole portion 3b, the locking tool 1 is moved along the wire rope 6 while pulling the rope 12, and the rope 12 is pulled until it is tense and the hand is released. The locking tool 1 is inclined by the tension of the rope 12.

In this inclined state, the opposite edges of the round hole 3b are pressed against the wire rope 6, so that the locking tool 1 is fixed to the wire rope 6, and therefore, By using the rope 12 and the locking tool 1 on the other side of the supporting rod 10 in the same manner and tensioning the rope 12, the upper end of the supporting rod 10 is pulled by the rope 12 from the direction of 180 degrees. It is fixed in the standing state.

Moreover, since the width of the opening 3a of the wire rope locking hole 3 is smaller than the maximum diameter of the wire rope 6, the position of the minimum diameter of the wire rope 6 and the opening 3a must be aligned. Since the stopper 1 cannot be disengaged from the wire rope 6, the stopper 1 does not disengage from the wire rope 6 indiscriminately.

In the embodiment described above, the rope 12 is attached to the attachment hole 2 of the locking tool 1 via the fastener 13, but the tip of the rope 12 is inserted into the attachment hole 2. Of course, they may be tied together and fixed.
