Moreover, as for this Braille 鋲 1, the luminescent resin layer which comprises the light emission part 12 accumulates sunlight outdoors, and also accumulates the light of a fluorescent lamp indoors. And in the dark, such as at night or during a power failure, it can emit light and obtain an inductive effect. Note that the light emitting effect of the light emitting portion 12 is amplified by the reflective layer 11 provided at the bottom of the recess 10.

Moreover, in this first reference example , the light emitting portion 12 made of one light emitting resin layer is formed by filling the light emitting pigment in the concave portion 10 having a small diameter at the upper end opening and heating it. Even if it is installed on the roadway, the manufactured original state can be reliably maintained without the light emitting part 12 being detached due to friction with the tires of the vehicle.

In the first reference example , the light emitting portion 12 and the anti-skid groove 13 form a predetermined pattern, so that a design decoration effect can be obtained. In addition, the anti-skid groove 13 can provide a non-slip function substantially the same as that of a conventional surface layer made of resin or rubber, and the head 8 of the embedded shaft 6 constituting the main body 2 is directly processed. There is no breakage or separation.

4A and 4B show the Braille 点 1 of the second reference example . In the second reference example , the first reference is provided in that a concave portion 10 ′ in which the light emitting portion 12 is provided is continuously provided above the insertion hole 5 for inserting and arranging the embedded shaft 6 formed in the base body 4.

In the center of the bottom surface of the recess 10 ′, an inverted convex insertion hole 5 is provided for inserting the embedded shaft 6 and positioning the head 8.

As in the first reference example , the embedded shaft 6 is formed by forming a head 8 that substantially coincides with the large-diameter upper portion 5a of the insertion hole 5 at the upper end of the shaft.

Braille tack 1 of the second reference example, as in the first reference example, is integrally fixed by press working. Specifically, as shown in FIG. 4B, the base body 4 is disposed in the lower mold of the press machine, and the embedded shaft 6 is inserted through the insertion hole 5 of the base body 4.

Next, the upper die is lowered to press the head 8 of the embedded shaft 6 downward, and the lower end periphery of the insertion hole 5 in the base 4 is plastically deformed by a caulking method, and the embedded shaft 6 is press-fitted into the base 4. To do. Thereby, in the lower part of the base body 4, the plastically deformed portion is deformed into the insertion hole 5, and the outer peripheral portion of the upper shaft portion 7 a corresponding to the deformed portion is simultaneously inward (axial center). Plastic deformation toward. As a result, similarly to the first reference example , the base body 4 and the embedded shaft 6 can be firmly fixed integrally. In the second reference example , the anti-skid groove 13 shown in the first reference example is not formed.

  Then, after forming the reflective layer 11 on the bottom of the concave portion 10 ′ closed by the head 8 of the embedded shaft 6, the upper portion thereof is filled with powdered or granular luminescent pigment and resin material and heated. The light emitting part 12 made of one light emitting resin layer is formed by melting and curing the light emitting pigment and the resin material.

Braille tack 1 of the second reference example, after which it is possible to obtain the same operation and effect as the first reference example, since the buried shaft 6 processing to form a recess 10 is not required, the first reference Compared to the configuration of the example , it can be manufactured at low cost.

FIG. 5 shows the Braille 鋲 1 of the third reference example . This third reference example is different from the first reference example in that the main body 2 and the shaft portion 3 are integrally formed. Even if it does in this way, the effect | action and effect similar to a 1st reference example can be acquired.

6 and 7 show a Braille ridge 1 according to an embodiment of the present invention . In the present embodiment , as in the third reference example , the main body 2 and the shaft portion 3 are integrally formed, and the outer peripheral edge of the light emitting portion 12 constituting the guiding portion is formed by plastic deformation at the upper end opening edge of the recess 10. The present embodiment is different from the above-described reference examples in that a protrusion 25 to be locked is provided.

Specifically, the Braille ridge 1 of the present embodiment is integrally formed so that a shaft portion 3 having an annular groove 9 projects downward at a predetermined interval at the center of the bottom surface of the main body 2 made of a hard metal such as stainless steel. Is formed. In the center of the main body 2, a truncated cone-shaped concave portion 10 for arranging the light emitting portion 12 is formed. As shown in FIG. 7A, a protrusion 25 protruding upward is provided at the opening edge of the recess 10 before finishing.

The light emitting section 12 made of the light emitting resin layer of the present embodiment uses a light emitting pigment and a resin material similar to those in the first reference example formed in a disc shape. Here, the light emitting section 12 may be either one having the same diameter on one surface and the other surface, or having a trapezoidal cross section in which the diameter of the one surface and the other surface are different by punching with a press or the like. Can be used. As shown in FIG. 7A, the diameter of the light emitting portion 12 having the same diameter on one surface and the other surface is formed to be substantially the same as the diameter of the upper end opening of the protrusion 25. On the other hand, the light emitting portion 12 having a trapezoidal cross section is formed such that the diameter of the small surface is substantially the same as the diameter of the upper end opening of the protrusion 25.

The braille rod 1 of the present embodiment is finished in a state in which the light emitting portion 12 cannot be detached by pressing, and a non-slip groove 13 is formed as in the reference example . Specifically, as shown in FIGS. 7A and 7B, a lower die 20 having a positioning recess 21 slightly larger than the main body 1 is used for this pressing. The lower mold 20 is provided with the insertion recess 22 of the shaft portion 3 at the center of the positioning recess 21, but is not provided with the ring-shaped press-fit portion 23 shown in the first reference example . Further, the upper mold (not shown) is provided with a convex portion for forming the anti-skid groove 13.

  Then, as shown in FIG. 7A, the main body 1 and the shaft portion 3 are disposed in the positioning recess 21 and the insertion recess 22, and the disc-like reflection layer 11 and the light emitting portion 12 are disposed in the recess 10. To do. Here, as shown in FIG. 7A, the light emitting portion 12 having the same diameter on one surface and the diameter on the other surface can be disposed in the recess 10 without any resistance. On the other hand, the light-emitting part 12 having a trapezoidal cross section can be disposed in the recess 10 while the light-emitting part 12 is deformed by slightly pressing the large-diameter side downward.

  Next, the upper die (not shown) is lowered to pressurize the main body 2 downward. As a result, as shown in FIG. 7B, the upper mold is plastically deformed into the recess 10 so that the protrusion 25 is substantially flush with the upper surface of the main body 2. At the same time, the convex portion of the upper mold is press-fitted into the main body 2 to form a non-slip groove 13 by plastic deformation.

  Thereby, in the recessed part 10, the upper end edge of the light emission part 12 formed in disk shape is deform | transformed by the deformed protrusion 25, and it acts so that the clearance gap between the inner surface of the recessed part 10 and the light emission part 12 may be filled up. In the drawing, the gap is described as completely filled, but the deformation action varies depending on the resin material used.

As in the first reference example , the Braille 鋲 1 formed in this way emits light in the dark such as at night or during a power failure, and can obtain an induction effect. Moreover, in this embodiment , since the luminescent resin layer is comprised by the light emission part 12 which makes | forms a disk shape, the process is easy and it can manufacture at low cost. Moreover, since the light emitting portion 12 is locked by the projecting portion 25 whose upper end edge is plastically deformed, the light emitting portion 12 is detached due to friction with the tire of the vehicle even if the Braille rod 1 is installed on the roadway. Without being done, the manufactured original state can be reliably maintained.

  The guide rod of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.
