  The present invention relates to, for example, improvement of a breaker bar with an indicator lamp of a breaker installed in a passage in front of a toll collection booth on a toll expressway, and particularly relates to a protective measure for electric wiring energized to the indicator lamp.

  The passage in front of the toll booth, such as toll expressways that have introduced an automatic toll collection (ETC) system, is shut off so that the toll collector does not cause a contact accident with the passing vehicle when crossing the passage. A machine is installed.

  Such a breaker has a breaker bar whose base end is supported rotatably in the vertical direction on the breaker body, and the breaker bar blocks the passage in a horizontal posture rotated downward with the base end as a fulcrum. While preventing the vehicle from entering, the passage is opened in a vertical posture rotated upward with the base end as a fulcrum to allow the vehicle to enter.

  As such a shut-off bar, Patent Document 1 states that in order to inform the driver of the vehicle that is about to enter the passage before the toll booth, the shut-off bar is blocking the passage in a horizontal posture. A blocking bar provided with an indicator light for arousing is disclosed.

  The material of the core member 13 is not limited, but is made of a metal pipe material such as stainless steel or a resin pipe material such as polycarbonate, carbon fiber reinforced plastic (CFRP), or glass fiber reinforced plastic (GFRP). It is preferable that it is difficult to break with moderate flexibility and rigidity. In this example, as shown in FIG. 4 and FIG. 5 with resin hatching, it is a resin core 13, which is a little so that it can be easily inserted into the elastic cylinder 15. The taper shape gradually decreases in diameter from the end to the end. Further, the shape of the core member 13 is not particularly limited, but a cross-sectional perfect circle, a cross-sectional ellipse, a cross-sectional polygon (triangle, quadrangle, pentagon, hexagon, etc.) may be employed. In this example, as shown in FIGS. 4 and 5, the core material 13 has a true circular cross section. In addition, although the core material 13 may be solid, when considering weight reduction and a softness | flexibility, it is preferable to comprise with the pipe material which has a hollow part.

  On the other hand, the elastic cylinder 15 may be made of any material as long as it has a buffer function for absorbing and mitigating the impact at the time of a vehicle collision. For example, polyethylene, polypropylene, ethylene / propylene copolymer, etc. Olefin resins are preferred. Further, the shape of the elastic cylinder 15 is not particularly limited, but a cross-sectional perfect circle, a cross-sectional ellipse, a cross-sectional polygon (triangle, quadrangle, pentagon, hexagon, etc.) may be employed.

  Further, as shown in FIG. 4, a plurality of triangular ribs 27 having a triangular cross section are integrally formed on the inner peripheral surface of the elastic cylinder 15 so as to extend continuously in the longitudinal direction of the bar at intervals in the circumferential direction. A concave groove 29 is formed between the adjacent ribs 27 and extending continuously in the bar longitudinal direction. Further, the tips of the ribs 27 are in contact with the outer peripheral surface of the core member 13, and the opening on the opposite bottom side of the concave grooves 29 is closed by the outer peripheral surface of the core member 13. 13 and the elastic cylindrical body 15, a plurality of trapezoidal gaps 31 are partitioned by adjacent rib ribs 27 of the plurality of rib ribs 27 and spaced in the circumferential direction, respectively, in the longitudinal direction of the bar. It is formed so as to extend continuously. In this example, the shape of the rib ribs 27 is a triangular cross section. However, the shape is not limited to this, and may be a quadrangular cross section (square, rectangular, trapezoid, etc.), a semicircular cross section, or the like. From the viewpoint of efficiently obtaining a cushioning effect, a cross-sectional triangle or a semicircular cross-section that is in a line contact state, particularly a cross-sectional triangle is preferable. Further, by providing the protruding ribs 27 on the inner peripheral surface of the elastic cylinder 15, it becomes easier to insert the tapered core member 13.

  As shown in FIG. 3 and FIG. 5, an annular resin spacer 33 is fitted outside the core lamp 13 on the indicator lamp mounting position and the base end side, and the spacer 33 is also elastically attached. Similar to the cylindrical body 15, a shrinkable tube 25 made of a shrink film is covered. In addition, the spacer 33 is cut along the center line, and a slit 33a that is continuous with one of the plurality of gaps 31 is formed at the cut portion. The thickness of the spacer 33 is set to be equal to or slightly thicker than the depth of the concave groove 29, and the spacer 33 has a plurality of gaps between the elastic cylindrical body 15 and the core member 13 except for the slit 33 a. 31 is closed so as not to be exposed to the outside. The spacer 33 may be made of metal, but is preferably made of resin in consideration of insulation.
