[0003] [Patent Document 1] JP 2016-123201 A [Patent Document 2] Japanese Utility Model Application Publication No. 6-43016 Summary of the Invention [Problem to be solved by the invention]

[0004] Since it is preferable for the cone bar to have high visibility at night, some bars have illuminators built into them. Naturally, if you try to improve visibility by increasing the amount of light emitted by the illuminator, you will need power according to the amount of light, and you will need a battery or power supply system to match that. This makes the structure of the cone bar itself complicated and heavy, which reduces visibility. The present invention has been devised in consideration of the above circumstances, and its object is to provide a cone bar that has high visibility and good transmittance. [Means for solving the problem]

[0005] In view of the above problems, the present invention has the following configuration: A cone bar comprising a thin plate-like light-emitting unit with multiple LEDs arranged inside along the longitudinal direction, and a rod-shaped frame with a flat surface on which multiple light-emitting units can be arranged along the longitudinal direction, a controller and a power source for controlling the light emission of the LEDs mounted on the light-emitting unit are provided within the frame, and mounting parts with engagement holes for mounting to the top of a cone-shaped road cone are provided on both ends of the frame, and the mounting parts are configured so that they can be mounted to the draw cone from either the top or bottom.

[0006] In addition, the present invention has the following configuration. That is, in the above-mentioned cone bar, The light-emitting unit is composed of a circuit board with LEDs arranged on its surface and a translucent cover body that covers the circuit board. The cover body has an outer shape that indicates the direction of travel by being pointed on one of its longitudinal sides, and has a large number of fine reflective surfaces that function as reflectors on its inner surface except for the part facing the LEDs.

[0007] The present invention also has the following configuration: In the above-mentioned cone bar, the frame is configured to be foldable by a hinge provided at approximately the center in the longitudinal direction. Effect of the Invention

[0008] The cone bar of the present invention has a structure in which multiple thin plate-shaped light-emitting units are arranged. Therefore, the light-emitting surface is wide and easy to see from a distance. In addition, the shape of the light-emitting unit itself has the function of guiding the direction of travel, so if you want to change the direction of travel, you can simply turn the cone bar upside down and attach it to the road cone.

[Diagram 2] FIG. 4 is a perspective view of the cover body as viewed from the inside. [Diagram 3] FIG. 2 is a perspective view of the cone bar in a folded state. [Figure 4] FIG. 2 is a perspective view showing an upside-down cone bar. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an external perspective view of a road cone bar 1 according to this embodiment. The road cone bar 1 has a frame 2 made of a lightweight steel plate as a long member having a rectangular cross section in the shape of a C-channel. Both ends of the frame are provided with mounting parts 3 and 4 having circular holes for mounting the road cone RC to the top of the road cone RC. Note that the illustration of mounting screws, wiring, connectors, etc. is omitted.

[0009] The cone bar 1 has a narrow flat surface 5 that faces horizontally along the long axis direction when the mounting parts 3 and 4 are mounted on the top of the road cone RC. In other words, the flat surface 5 is arranged perpendicular to the circular holes that make up the mounting parts 3 and 4. A light-emitting unit 6 with multiple LEDs 7 arranged inside is mounted on this flat surface 5. The light-emitting unit 6 is composed of a circuit board 8 with LEDs 7 arranged on its surface and a cover body 9 that covers the circuit board 8. The circuit board 8 is driven and controlled by a controller (not shown) provided inside the cone bar 1, and the LEDs 7 and the circuit board 8 are supplied with power from a detachably attached battery 10.

[0010] 1 is configured such that a circuit board 8 is fixed to the surface of the flat surface 5 and a cover body 9 is attached thereon. However, the circuit board 8 and the cover body 9 may be integrally assembled into a light-emitting unit 6 that can be handled as a single unit, and the light-emitting unit 6 may be configured to be attached, handled, and controlled as a single unit.

[0011] FIG. 2 shows a perspective view of the cover body 9 as seen from the inside. The cover body 9 has a plate-like exterior shape with an internal space 19 shaped to cover and accommodate the circuit board 8 on which the LEDs 7 are mounted, and is formed by injection molding a translucent resin material. It can also be colored in any color, such as orange, red, transparent, or other colors, depending on the application and purpose. Although not shown, a waterproof function may be provided on the outer periphery to prevent the circuit board 8 from becoming submerged in water during bad weather.

[0012] As an example, the cover body 9 has a slightly long and thin plate-like appearance, and one end 20 in the longitudinal direction is formed in a pointed shape like the triangle at the tip of an arrow. In this embodiment, the end opposite to the pointed end 20 is configured as a triangular cutout 21, and the outline of the cover body 9 together with the pointed end 20 at one end indicates the direction in which the vehicle or the like is guided. A fine multi-faceted pattern 22 with adjacent portions differing in inclination direction is provided on the flat surface of the internal space 19 facing the circuit board 8. The multi-faceted pattern 22 is a reflective surface configured to function as a so-called reflector, and when light is irradiated from the front surface side, it appears to emit light through diffuse reflection, and has the effect of visually calling the viewer's attention.

[0013] Furthermore, in the plane on which the multifaceted pattern 22 is formed, the portion facing the LED 7 provided on the circuit board 8 is a light-transmitting surface 23 on which the multifaceted pattern 22 is not provided. The light-transmitting surface 23 is a portion formed as a recess having a flat bottom surface when viewed from the internal space 19 side, so that the light emitted by the LED 7 can be seen as it is. In addition, the inner wall of the recess has the effect of guiding the light emitted by the LED 7 to the flat portion forming the multifaceted pattern 22, so that the surroundings of the light-transmitting surface 23 can also be illuminated.

[0014] The multiple LEDs 7 arranged on the circuit board 8 can be made to emit light in various patterns by a controller. For example, it is possible to make all the LEDs 7 emit light, to make them flash in a flowing pattern from the cutout portion 21 side to the end portion 20, to make all the LEDs 7 flash simultaneously, or to make them emit light in a combination of these lighting patterns. Also, it is possible to control the lighting and extinguishing of each of the arranged light-emitting units 6.

[0015] The structure of the cone bar 1 will be described. The cone bar 1 is divided into two, and a single frame 2 is formed by connecting identically shaped divided frames 30 and 31 with a hinge 32. The hinge 32 is provided in the center of the cone bar 1, and the divided frames 30 and 31 can rotate relative to each other around the hinge 32, allowing the cone bar 1 to be reversibly transformed between an extended state and the folded state shown in Fig. 3. This structure allows the cone bar 1 to be folded for easy transport and storage, and can be unfolded when in use.

[0016] The cone bar 1 can be attached to the road cone RC by changing its orientation. That is, when it is rotated 180° in the direction of the arrow Y from the position shown in Fig. 1, it is turned upside down as shown in Fig. 4, and the light-emitting unit 6, which was pointing to the right side (arrow R), now points to the left side (arrow L). The reason why the cone bar 1 can be used on both the right side (arrow R) and the left side (arrow L) is because the mounting parts 3, 4 with circular holes provided at the ends of the divided frames 30, 31 are arranged symmetrically in the top-to-bottom direction.

[0017] Although one embodiment of the present invention has been described above, various improvements may be made in the details without departing from the technical scope of the invention described in the claims. [Explanation of symbols]
