In the figure, reference numeral 1 denotes a gripping body, which is constructed by screwing together a battery storage tube 2 and a tube 3 made of synthetic resin.
A plurality of batteries 4 are housed inside the battery housing tube 2, and the battery housing tube 2 includes a coil spring 5 connected to the batteries 3, a conductor 6 connected to the coil spring 5, and a switch connected to the conductor 6. 7 are assembled, and these parts and the battery 4 constitute a series electric circuit. A wiring board 9 incorporating electrical components 8 is provided inside the tube 3, and this wiring board 9 connects the battery 4 and conductor of the battery housing tube 2 when the battery housing tube 2 and the tube 3 are screwed together. 6 to form an electric circuit. Further, one socket 11A for a fluorescent lamp is attached via a socket receiver 10 to the end of the tube 3 opposite to the end screwed into the battery storage tube 2 (outer tube connection end). , this socket 11A is electrically connected to the wiring board 9 via a conductor (not shown). Note that the battery 4 is stored by removing the battery housing tube 2 from the tube 3. In the figure, reference numeral 12 denotes a cylindrical outer tube having a longer length than the gripping body 1, and is made of a translucent material, such as a transparent synthetic resin. This outer cylinder 12 is arranged on the same axis as the gripping body 1, and its one end opening is screwed and connected to the end of the gripping body 1 to which the socket 11A is attached, and the other end of the outer cylinder 13 An end cover 13 is screwed and attached to the opening. A socket 11B is attached to the end cover 13 via a socket receiver 14. Reference numeral 15 denotes an inner cylinder, which is formed as a rectangular cylinder that is smaller in size than the outer cylinder 12 and is open at both ends. As shown in FIG. 3, the inner cylinder 15 is constructed by combining four rectangular resin plates 16 made of, for example, red transparent synthetic resin into a cylindrical shape. Each resin plate 16 has a large number of small pyramidal projections 16a regularly arranged on its inner surface. As shown in FIGS. 4 and 5, this pyramidal projection 16a has the shape of a cube with half of it embedded inside the resin plate 16, and is a triangular pyramid formed by combining three rhombic slopes 16b. A large number of pyramidal projections 16a are formed by being arranged alternately in a staggered manner, and a recess in the form of an inverted pyramidal projection 16a is formed in a portion sandwiched by the pyramidal projections 16a arranged in a staggered manner. is formed. That is, the pyramidal projections 16a and the recesses are arranged alternately. Each pyramidal projection 1 lined up like this
6a can receive and reflect light incident from any direction on one of the three slopes 16b. The inner cylinder 15 is disposed inside the outer cylinder 12 along the longitudinal direction, one end surface of which contacts the end surface of the gripping body 1 to which the socket 11A is attached, and the other end surface of the inner cylinder 15 that contacts the inside of the end cover 13. The entire inner cylinder 15 is held stationary by contacting the end face. That is, the inner cylinder 15 has a grip body 1 and an end cover 1.
3 is pressed and held. In the figure, reference numeral 17 denotes a fluorescent lamp, which forms a straight line with a length corresponding to the inner tube 15. This fluorescent lamp 17 has an inner tube 1.
Terminals 18, 18 provided at both ends thereof are inserted into the socket 11A of the gripping body 1 and the socket 11B of the end cover 13. That is, the fluorescent lamp 17 is
It is provided over the entire length of 5. In addition, the inner cylinder 1
5 has two wiring holes 19 throughout the lengthwise direction.
19 is formed, and conductive wires 20, 20 are inserted into the wiring holes 19, 19, respectively. At one end opening of the inner tube 15, the ends of the conductive wires 20, 20 are in contact with a conductor (not shown) connected to the wiring board 9 and the socket 11A provided in the tube 3 of the gripping body 1. However, at the other end opening of the inner cylinder 15,
The ends of the conductive wires 20, 20 are in contact with a conductor (not shown) connected to the socket 11B provided in the end cover 13. Therefore, the sockets 11A and 11B are electrically connected via the conductive wires 20 and 20, and an electric circuit connecting the fluorescent lamp 17, the battery 4, the switch 7, and the circuit board 9 is constructed. Note that by removing the end cover 13 and opening the other end opening of the outer tube 12, the fluorescent lamp 17 can be inserted into and removed from the inner tube 15.

The outer cylinder 12 protects the inner cylinder 15 and increases the strength of the entire guide signal rod.

The operation of the guide signal rod configured in this way will be explained.

By operating the switch 7, the electric circuit connecting the battery 4, the circuit board 9 and the fluorescent lamp 17 is closed, and the fluorescent lamp 1 is closed.
Turn on 7. Here, since the fluorescent lamp 17 is provided over the entire length of the inner cylinder 15, the light emitted from the fluorescent lamp 17 illuminates the entire length of the inner cylinder 15. A part of the light emitted from the fluorescent lamp 17 hits the slopes 16b of the many pyramidal protrusions 16a formed on the inner surface of each resin plate 16 of the inner cylinder 15, and is reflected on the other resin plates 16. The light reaches the slope 16b of the inner pyramidal projection 16a and is reflected. In this way, a portion of the light is repeatedly reflected and travels in the axial direction inside the inner tube 15, and then passes through each resin plate 16 and exits the inner tube 15. Further, the other part of the light emitted from the fluorescent lamp 17 directly passes through each resin plate 16 and exits from the inner cylinder 15. When these lights pass through the inside of each resin plate 16, the slopes 16b of the many pyramidal protrusions 16a formed on the inner surface of the resin plate 16
The light is refracted and reflected and exits the inner cylinder 15 in a diffused state. Figures 1, 2, 4 and 5
In the figure, a broken line indicates an example of the progression of light.

In this way, the fluorescent lamp 17 illuminates the entire axial direction of the inner cylinder 15, and the light emitted by the fluorescent lamp 17 is diffusely reflected and diffused by the inner cylinder 15.
The whole area glows evenly and brightly. Therefore, the inner tube 15 shining brightly through the outer tube 12 can be clearly seen from the outside of the guide signal rod.

Therefore, when this guidance signal rod is used for guidance during road construction at night, for example, the guidance signal rod is displayed brightly and its presence can be easily confirmed from a distance.

[Effect of idea]

As explained above, the guide signal rod of the present invention uses a fluorescent lamp as a light source lamp, so that it can uniformly irradiate and reflect light over the entire length of the inner cylinder, and also allows the light of the fluorescent lamp to be reflected internally. Since the cylinder effectively reflects and diffuses, it has excellent optical display effects and can be easily seen even from a distance at night.
