JP 2007-126927 A

  Patent Document 1 discloses the following technique. The technique is a guide plate installed on a road surface. This guide plate is formed with a concavo-convex process on the surface of a metal plate, thereby forming a guide mark such as an arrow. Then, a phosphorescent phosphor is applied to the recesses, and a transparent resin is applied thereon to form a protective layer. In the dark, the phosphorescent phosphor applied to the recess emits light, and the guidance mark is lifted to ensure visibility.

  The invention is a guide plate installed on a road surface, on which a pedestrian, a vehicle, or the like passes. Then, although it has a protective layer, there is a possibility that the phosphorescent phosphor applied to the recesses may be peeled off by pressure or friction when it is stepped on. It is the cylindrical protrusion that plays the role of these protections.

  However, when this cylindrical convex part is manufactured by cutting out from the raw material of the guide plate, it takes time during manufacturing. Since it takes time and effort, there are also problems with cost and productivity. Moreover, although the method of making a hole in the recessed part of a guide plate and attaching a convex part from a guide plate upper part is also considered, there exists a possibility that sufficient intensity | strength cannot be obtained with this. This is because when a vehicle or a person passes over the guide plate, the pin may fall off due to pressure, impact, or friction at that time. Then, the phosphorescent phosphor is exposed, and the phosphor may be peeled off, which causes a problem that the guide plate body cannot sufficiently perform its function. Further, if a gap is generated between the hole for fixing the convex portion and the protruding portion, there is a possibility that leakage occurs when the phosphorescent phosphor is applied.

  Therefore, the problem to be solved by the present invention is that the road surface is provided with a convex portion (hereinafter referred to as a tread prevention pin) that is closely fixed to the guide plate, is robust against wear and pressure, and can withstand long-term use. It is to provide a mold induction plate.

  Moreover, 2nd invention provides the road surface installation-type guide plate by which the said tread prevention pin fits and is fixed with respect to the pin insertion hole based on 1st invention.

  3rd invention provides the road surface installation-type guide plate which the said tread prevention pin is screwed and fixed with respect to the pin insertion hole based on 1st invention.

  According to a fourth aspect of the present invention, there is provided a road surface installation type guide plate according to the second or third aspect of the invention, wherein the phosphorescent phosphor layer is formed by being cast into a region surrounded by the peripheral wall.

  5th invention provides the road surface installation-type induction | guidance | derivation board which the said surrounding wall forms a gentle skirt gradually toward the outward based on either of 1st to 4th invention.

  6th invention provides the road surface installation-type guide plate which the said surrounding wall has a wide part based on either of 1st to 5th invention, and the hole for road surface fixing tools is provided in the wide part. To do.

  In a seventh aspect based on any one of the first to sixth aspects, an island-shaped portion having a height equivalent to the top of the tread prevention pin is formed in a part of the region surrounded by the peripheral wall. A road surface installation guide plate is provided.

  According to the first aspect of the present invention, the road surface installation type guide plate has a tread prevention pin penetrating from the back surface of the base plate and protruding to the front surface, and a phosphorescent phosphor layer lower than the top of the tread prevention pin. Thereby, it is possible to prevent the phosphorescent phosphor layer from being peeled off due to friction and pressure at that time by passing a person or a vehicle. Further, by inserting the tread prevention pin from the back surface, it is possible to prevent the pin from falling off due to friction or the like.

  According to the second invention, the tread prevention pin is fitted and fixed to the pin insertion hole. Accordingly, since the pin can be inserted into the insertion hole with higher adhesion, the tread prevention pin can be fixed more firmly.

  According to the third invention, the tread prevention pin is fixed by being screwed into the pin insertion hole. Thereby, it is possible to more easily attach the tread prevention pin during manufacture.

  According to the fourth invention, the phosphorescent phosphor layer is formed by casting into a region surrounded by the peripheral wall of the base plate. Thereby, since it is only necessary to flow in the phosphorescent phosphor at the time of manufacture, it is possible to reduce the labor and cost at the time of manufacture compared to the case of applying the phosphor.

  According to the fifth aspect of the invention, since the peripheral wall forms a gradually skirt toward the outside, when passing over the guide plate, it can pass smoothly without scooping.

  According to the sixth invention, the peripheral wall of the base plate has a wide portion, and the wide portion is provided with a hole for a road surface fixing tool. It is possible to firmly fix the guide plate to the road surface by inserting and fixing the screw into the hole for the road surface fixing tool.

  According to the seventh invention, the base plate has an island-like portion having a height equivalent to the top of the tread prevention pin in a part of the region surrounded by the peripheral wall. By this island-shaped portion, a guide mark can be formed. When the phosphorescent phosphor poured around the induction mark emits light, the induction mark can be lifted up and visually recognized.
