DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a non-slip walking guide marker A according to a first embodiment of the present invention includes a convex elastic body 2 disposed on a road surface 1, a cylindrical body. A hollow rivet 3 having a head 3a formed by enlarging the periphery of one end and a shaft 3b at the other end, and a pull rod 4a which can be inserted through the hollow rivet 3
And a head plug 5 for closing the through-hole 2a of the convex elastic body 2 from the front side.

The road surface 1 includes entrances and corridors of buildings,
Examples include indoor and outdoor sidewalks, walkways in stores, and floors in waiting rooms of hospitals. These are generally based on concrete, but may be made of wood, stone, asphalt, or the like. The convex disc-shaped elastic body 2 has a through hole 2a whose diameter is reduced on the back surface side, penetrating the front and back surfaces of a central portion rising upward in a hemispherical shape, and a rivet insertion hole is provided at a position corresponding to the through hole 2a. This is a disk body in which a core material 2c having a core 2b is embedded. The surface side of the through hole 2a is a counterbore for immersing the head 3a of the hollow rivet 3.

On the back surface of the convex disk-shaped elastic body 2, there is formed a ring-shaped concave portion 6 which can be used as a glue reservoir when viewed from below, but may be omitted. In addition, on the surface of the convex disk-shaped elastic body 2, irregularities having a predetermined pattern are formed as well shown in FIGS. 2 and 3, and a relatively raised portion is defined as a convex portion 2d. More specifically, the convex portion 2d is a flat quadrangular pyramid-shaped protrusion that serves as a slipper for shoes or the like, and the four corners of the adjacent convex portions 2d are continuously formed in a knurled pattern. ing.

Examples of the material of the convex disk-shaped elastic body 2 include natural rubber, silicon, and foamed resin. Synthetic rubber excellent in abrasion resistance is preferable. In particular, it is preferable to use a hard rubber as a main raw material, which is applied to tires of automobiles, in consideration of being installed on a main street where traffic is frequent. As the core material 2c, a washer for bolts or the like may be applied, but it has a relatively high rigidity such as a synthetic resin plate or a metal plate and is easily deformed even when stepped on or kicked by a pedestrian. If not, the material and dimensions are not limited. Further, as shown in FIG. 4, by forming small holes 2e in the core material 2c, the adhesion between the material constituting the elastic portion of the convex disk-shaped elastic body 2 and the core material 2c is improved. Is also good.

As shown in FIG. 1, the hollow rivet 3 is preferably made of a metal such as aluminum which can be easily plastically deformed, but its diameter and overall length are arbitrary.
The wedge 4 with a pull rod is such that the outer diameter of one end 4b of a pull rod 4a made of a metal wire relatively harder than the hollow rivet 3 is enlarged so as to be larger than the inner diameter of the hollow rivet 3. is there. The head plug 5 is provided with a through hole 2 a of the convex elastic body 2.
It is a small disk with a slightly smaller outer diameter, and its surface has substantially the same curvature as the convex elastic body 2 so as to obtain an integrated appearance with the convex elastic body 2 with the through hole 2a closed. Preferably, it protrudes upward. In particular, when the convex portion 2d is formed on the convex disk-shaped elastic body 2, the convex portion 2d is also formed on the surface of the head plug 5.
Is preferably formed.

In order to fix the convex elastic body 2 to the road surface 1, first, a prepared hole 7 deeper than the entire length of the hollow rivet 3 is dug down at an appropriate position on the road surface 1 using an electric drill or the like. Then, the pull bar 4a of the wedge 4 with the pull bar is inserted into the shaft portion 3b of the hollow rivet 3 from the side opposite to the head portion 3a, and the hollow rivet 3 exposing one end 4b whose diameter has been expanded is formed into a convex disk-shaped elastic member. By inserting the head 3a of the hollow rivet 3 into the through hole 2a by inserting the through hole 2a and the rivet insertion hole 2b from the surface side of the body 2, the shaft portion 3b is inserted through the through hole 2a to form a convex elastic. The convex elastic body 2 is placed on the road surface 1 by protruding to the rear surface side of the body 2 and immersing in the prepared hole 7 of the road surface 1. At this time, by making the pull rod 4a sufficiently long, the other end 4c of the pull rod 4a of the wedge 4 with the pull rod is in a state of protruding toward the surface side of the convex elastic body 2.

Subsequently, as schematically shown in FIG. 5, a guide sleeve 8 for inserting the pull rod 4a of the wedge 4 with a pull rod, and the other end 4 of the pull rod 4a projecting from the rear end of the guide sleeve 8 are provided.
c, and when the head 3a of the hollow rivet 3 is pressed by the distal end surface 8a of the guide sleeve 8, the holding pair 9 retreats in the direction of arrow a away from the head 3a. The forehead 4a of the wedge with drawbar 4 is forcibly pulled out to the front side of the convex disk-shaped elastic body 2 while the head 3a of the hollow rivet 3 is pressed against the back side using the special tool 10 configured as described above.

Thus, one end 4b of the wedge 4 with the drawbar
Presses into the shaft portion 3b of the hollow rivet 3, the shaft portion 3b of the hollow rivet 3 is pushed and expanded. Since such expansion of the shaft portion 3b is a plastic deformation, the stress generated in the hollow rivet 3 becomes a resistance of the operation of pulling out the pull bar 4a to the surface side, and the wedge 4 with the pull bar has one end 4b at the shaft portion 3b.
In the process of press-fitting into the steel, it continues to receive a tensile load.

Further, when the pull rod 4a of the pull wedge 4 is pulled out to the front side, as shown in FIG. 6, the shaft portion 3b of the hollow rivet 3 is pressed against the inner peripheral surface of the pilot hole 7, and the hollow rivet 3 is pressed. Is fixed firmly to the road surface 1 together with the convex elastic body 2. In addition, since the expansion of the shaft portion 3b is limited when the shaft portion 3b is pressed against the inner peripheral surface of the pilot hole 7, the tensile load received by the wedge 4 with the pull rod rapidly increases, and the wedge 4 with the pull rod Due to the different outer diameters of the pull rod 4a and its one end 4b, a concentrated load is applied to the vicinity of these boundaries and both break, leading to the separation of the pull rod 4a from the one end 4b. .

Finally, the pull rod 4 divided from one end 4b
a is removed to the outside of the through hole 2a, and the head plug 5 is pushed into the through hole 2a from the surface side of the convex elastic body 2 so that the surface thereof is substantially flush with the surface of the convex elastic body 2. Then, the through-hole 2a is closed, the head 3a of the hollow rivet 3 is concealed, and infiltration of rainwater or the like into the through-hole 2a and the hollow rivet 3 can be prevented.

In the above description, the convex plate-shaped elastic body 2 is fixed to the road surface 1 only by pressing the shaft portion 3b of the hollow rivet 3 against the inner peripheral surface of the pilot hole 7, but the adhesive ( (Not shown) may be used to improve the reliability of construction. Specifically, the shaft portion 3b of the hollow rivet 3 and the prepared hole 7
If an adhesive is applied to the inner peripheral surface of the hole, rainwater etc.
In addition to preventing slippage between the hollow rivet 3 and the pilot hole 7 caused by infiltration into the hole, the convex rivet 3 may be kicked by a passerby in the pilot hole 7 of the hollow rivet 3. Swing can be prevented. In addition, an adhesive may be applied to the back surface of the convex elastic body 2 so that the peripheral edge of the convex elastic body 2 does not warp upward and peel off from the road surface 1. In this case, if the adhesive is applied to the concave portion 6, the adhesive is prevented from leaking outward from the peripheral edge of the convex elastic body 2 even if the convex elastic body 2 is stepped on and pressed. it can.

If the convex elastic body 2 has a raised shape with respect to the road surface 1, the convex elastic body 2 has a trapezoidal disk shape as shown in FIG. 7 or a disk shape shown in FIGS. 8 (a) to 8 (c). It may be a long plate material as shown. When the convex elastic body 2 is long as described above, the through holes 2a are formed at a plurality of positions of the convex elastic body 2 and the core material 2c is also rivet by applying a long one. The insertion holes 2b are formed at a plurality of locations. Then, a hollow rivet 3 and a wedge 4 with a draw bar may be used for each through hole 2a and each insertion hole 2c, and the construction may be performed according to the above procedure. When the convex elastic body 2 is made of a material having a relatively large coefficient of friction, the surface of the convex elastic body 2 may be finished smoothly by omitting the convex portion 2d.

Next, as shown in FIG.
The non-slip walking guidance marker B according to the embodiment of the present invention is attached to the floor covering 12, and the convex-shaped elastic body 13 exposing the end of the rivet immersion cylinder 13a from the back side, the hollow rivet 3, and the pull It comprises a wedge with a bar 4 and a receiving plate 14 which is arranged on the back side of the floor covering 12 and has an insertion hole 14a formed at a position corresponding to the rivet immersion cylinder 13a of the convex elastic body 13.

The floor covering 12 includes a base sheet 12
A carpet or the like in which the woolen material 12b is fixed to a may be used, but a flooring material, a wooden board, a tile, a synthetic resin board, a gypsum board, or the like laid in a room or a corridor of a building may be used. As shown in FIGS. 9 and 10, the convex disc-shaped elastic body 13 has the same configuration as that of the convex disc-shaped elastic body 13 except that a core material 13b obtained by welding or brazing a rivet immersion cylinder 13a to the back surface is embedded in a central portion. Since it has substantially the same shape as the disk-shaped elastic body 2, detailed description is omitted.

As the rivet immersion cylinder 13a, a steel sleeve can be used, but any short pipe having higher rigidity and higher toughness than the hollow rivet 3 may be used. The receiving plate 14
Is formed by drilling an insertion hole 14a in the center of a circular plate in a plan view, and presses the outer periphery of the insertion hole 14a to the surface side so that the head 3a of the hollow rivet 3 is deep enough to be immersed. By doing so, the tapered surface 14b may be formed.

In order to fix the convex elastic body 13 to the floor covering 12, first, the convex elastic body 13 larger than the outer diameter of the rivet immersion cylinder 13a and the receiving plate 1 are put in place on the floor covering 12.
The marker mounting hole 16 having a diameter smaller than the outer diameter of No. 4 is pierced using a circular cutter or the like. A pull rod 4 of a wedge 4 with a pull rod is mounted on the shaft 3b of the hollow rivet 3 from the side opposite to the head 3a.
a is inserted to expose the one end 4b whose diameter has been increased. Further, the receiving plate 14 is arranged on the back side of the floor covering 12, and the hollow rivet 3 is inserted from the back side of the receiving plate 14 into the insertion hole 14a.
The head 3a of the hollow rivet 3 is locked to the tapered surface 14b, and the shaft 3b, whose one end 4b having the increased diameter is exposed, is projected toward the surface of the receiving plate 14.

In this state, as shown in FIG. 11, the rivet immersion hole 13a of the convex disc-shaped elastic body 13 which is disposed on the surface side of the floor covering 12 and has the rivet immersion hole 13a inserted into the marker mounting hole 16 is provided. Then, one end 4b of the pull rod 4a of the wedge 4 with the pull rod is immersed together with the shaft part 3b protruding to the surface side of the receiving plate 14. Subsequently, the pulling rod 4a of the wedge 4 with the pull rod is forcibly pulled out to the back side of the floor covering 12 while pressing the head 3a of the hollow rivet 3 against the front side of the floor covering 12 using the special tool 10. Since the one end 4b of the pull rod 4a is pressed into the shaft 3b of the hollow rivet 3, the shaft 3b of the hollow rivet 3 is pushed and expanded.

Further, when the pull rod 4a of the pull wedge 4 is pulled out to the back side, the shaft portion 3b of the hollow rivet 3 comes into pressure contact with the inner peripheral surface of the rivet immersion cylinder 13a, and the hollow rivet 3 becomes a convex elastic body. At the same time as being firmly fixed to 13, the pull bar 4a is separated from its one end 4b as described above. Through the above steps, the outer periphery of the marker mounting hole 16 of the floor covering 12 is sandwiched between the convex elastic body 13 and the receiving plate 14.

The convex disk-shaped elastic body 13 may be a trapezoidal disk as shown in FIG. 12 or a disk shown in FIGS. ) May be used. When the convex-plate-shaped elastic body 13 is made to be long, the rivet immersion cylinders 13a are provided at a plurality of positions of the convex-plate-shaped elastic body 13, and the receiving plate 14, the hollow rivet are provided for each of the rivet immersion cylinders 13a. The construction may be performed according to the above-described procedure using the wedge 3 and the wedge 4 with the drawbar. Further, the receiving plate 14 may be long and the insertion holes 14a may be formed at a plurality of locations. The convex elastic body 13 may be directly bonded to the floor covering 12 by applying an adhesive to the concave portion 6 of the convex elastic body 13.

Furthermore, in the above description, the operation of inserting the wedge 4 with the pull rod into the hollow rivet 3 is performed at the time of construction, but the pull rod 4a of the wedge 4 with the pull rod is inserted into the hollow rivet 3 in advance. In advance, the man-hour at the time of construction may be reduced. In this case, the pull bar 4a of the wedge 4 with a pull bar is set so that the hollow rivet 3 and the wedge 4 with the pull bar do not separate before the application.
Is preferably a close fit that cannot be easily pulled out of the hollow rivet 3 by hand.

According to the non-slip walking guide marker according to the first aspect, when the convex elastic body is fixed to the road surface, it can be used as a signpost for visually impaired persons as well as the conventional walk guide marker. When a passerby steps on the convex-shaped elastic body, the convex-shaped elastic body is slightly elastically deformed and adheres to the sole of the shoe. can get. In addition, since the core material is embedded in the convex-shaped elastic body, even when the convex-shaped elastic body is kicked by a pedestrian or the like, it does not deform or warp and peel off from the road surface, and has excellent durability. .

Further, there is an advantage that the convex elastic body can be securely fixed to the road surface without using a tapping screw or an adhesive which requires a complicated screwing operation. That is, with the shaft portion of the hollow rivet projecting to the back side of the convex disc-shaped elastic body immersed in a prepared hole or the like dug down on the road surface, pull out the pull rod inserted through the hollow rivet from the head of the hollow rivet to the front surface side. Thus, when one end of the wedge with the draw bar is pressed into the shaft of the hollow rivet, the shaft of the hollow rivet expands and presses against the inner peripheral surface of the pilot hole or the like. On the other hand, the head of the hollow rivet is locked in the through hole of the convex elastic body reduced in diameter on the back side, and the convex elastic body is fixed in the radial direction of the through hole by the core material. Because it is reinforced so that it does not expand and contract, the through hole does not expand due to the elastic deformation of the convex elastic body, and the head of the hollow rivet does not pass through the through hole to the back side. As long as the shaft of the hollow rivet does not come out of the pilot hole, This is because there is not to be detached from the rivet.

Further, by closing the through hole of the convex elastic body with a head plug, the head of the hollow rivet and the inside of the through hole can be concealed to improve the appearance.

According to the non-slip walking guide marker according to the second aspect, when the convex elastic body is attached to the floor covering, it can be used as a guidepost for a visually impaired person as well as a conventional walk guide marker, and can be used for traffic. When a person steps on the convex-shaped elastic body, the convex-shaped elastic body is slightly elastically deformed and adheres to the sole of the shoe, so that there is an advantage that the shoes do not slip and the walking safety can be secured. Can be In addition, since the core material is embedded in the convex elastic body, even when the convex elastic body is kicked by a pedestrian or the like, it does not deform or warp and peel off from the road surface,
Has excellent durability.

Another advantage is that the convex disk-shaped elastic body can be securely attached to a flexible floor covering. That is, with the shaft portion of the hollow rivet projecting to the front surface side of the receiving plate being immersed in the rivet immersion cylinder of the convex-shaped elastic body, pulling the pull rod inserted through the hollow rivet from the head of the hollow rivet to the back surface side. Accordingly, when one end of the wedge with the draw bar is pressed into the shaft of the hollow rivet, the shaft of the hollow rivet expands and presses against the inner peripheral surface of the rivet immersion cylinder of the convex elastic body.
The shaft of the hollow rivet is firmly fixed to the convex-shaped elastic rivet immersion cylinder, while the head of the hollow rivet is engaged with the through hole of the receiving plate, so that the shaft of the hollow rivet is immersed in the rivet immersion cylinder. This is because the convex-shaped elastic body does not come off from the hollow rivet as long as the floor-shaped elastic body and the receiving plate are sandwiched while the floor rug is sandwiched.

According to the non-slip walking guide marker of the third aspect, the convex portion formed on the surface of the convex elastic body is caught or slightly bites into the shoe sole of the passerby, so that the slip of the shoe or the like is prevented. You can stop it. In addition, even when the surface of the convex-shaped elastic body is wetted during rainy weather or when water is sprinkled, even if the coefficient of friction of the convex-shaped elastic body is reduced, it is possible to avoid a situation in which shoes and the like become extremely slippery.

According to the construction method of the non-slip walking guide marker according to the fourth aspect, when the convex elastic body is installed on the road surface made of concrete, stone, or the like, as in the construction procedure described above, Work can be performed quickly and easily without using tapping screws. Further, there is an advantage that the convex-plate-shaped elastic body can be easily installed simply by digging a pilot hole in an appropriate place on an existing road surface.

According to the construction method of the non-slip walking guide marker according to the fifth aspect, the floor covering is sandwiched between the floor covering by the convex elastic body and the receiving plate as in the construction procedure described above. Because the convex elastic body and the receiving plate can be firmly connected with each other, the convex elastic body does not inadvertently separate from the floor covering, and the convex elastic body can be securely attached to the floor covering. it can. In addition, there is an advantage that the convex-plate-shaped elastic body can be easily attached simply by piercing the marker attachment hole in an appropriate place of the existing carpet or flooring material.
