Description

  The present invention is embedded in roads, sidewalks, building floors, stairs, etc., to guide drivers and pedestrians (eg visually impaired, children, elderly people, etc.) to assist driving and walking. The present invention relates to a guide housing for drivers and pedestrians.

  Patent Document 1 discloses an example of a walking derivative. As described in Paragraph 0002 and Paragraph 0003 of this Patent Document 1 (FIGS. 8A and B which are conventional examples of Patent Document 1) and the embodiment of Patent Document 1 (for example, FIG. 1A and B), respectively. The walking derivative is generally made of a metal substrate-shaped head (substantially flat substrate), a metal plate having a spiral threaded portion on its peripheral side, with its upper end fixed to the substantially central portion of the substrate-shaped head. A thick surface layer made of resin or rubber is provided on the upper surface of the substrate-like head to cover substantially the entire upper surface.

  For example, when the above-mentioned walking derivative is embedded in the upper surface of the road surface of a road or a sidewalk, vehicle tires, pedestrian shoes, etc. get on the surface layer. The layer is easily scratched, and wear and deterioration occur. In particular, in order to make the surface layer a landmark for pedestrians, for example, when it is made of a phosphorescent ceramic-containing plastic piece (Patent Document 2), it is worn, damaged or deteriorated due to friction, and the brightness function of the surface layer is reduced. It is not preferable. In addition, when the upper surface of the surface layer is formed in a slightly arc shape to enhance visibility, the substantially central portion of the surface layer is more worn, damaged, or deteriorated than the peripheral end portion, and similarly the luminance function of the surface layer Decreases.

When entering the receiving recess and the entire adhesive is cured, it is possible to prevent loosening of the buried shaft due to vibration.
(5) In the device according to claim 5, the same effect as in the above (1) can be obtained, and the identification layer includes a highly weather-resistant phosphorescent particle body coated with a polymer resin, and an organic honeycomb structure. Since it is a cured resin body in which a polymer and porous inorganic powder are mixed, it is possible to sufficiently ensure visibility and to be used for a long time.
(6) In the device according to claim 6, the surface of the arcuate recess or arc-shaped through hole of the substrate-like head extends from the upper surface, which is a substantially flat surface at the center of the substrate-like head, to the peripheral end. Since the slightly inclined identification layer is provided in the close contact state, the same effect as the device according to claim 1 is obtained.
(6) Also in the device according to claim 7, the surface of the recess or the through hole of the substrate-like head is somewhat from the upper surface, which is a substantially flat surface of the central portion of the substrate-like head, to the peripheral edge.

  Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. A driver or pedestrian guide housing X according to the first embodiment for carrying out the present invention shown in FIGS. 1 to 5 is basically a metal substrate having a thick annular identification layer 2. The head portion 1 and the center portion 5 of the substrate-like head portion 1 are appropriately fixed in a state where the upper end portion is inserted into the center portion 5 of the substrate-like head portion 1, and downward from the center of the lower surface of the substrate-like head portion 1. It consists of a metal embedded shaft 3 that extends vertically and has a helical thread portion 4 on its peripheral side surface.

  As shown in FIGS. 1 and 2, the substrate-like head 1 has a disk shape and a substantially flat shape as a whole. In the embodiment, the lower surface 1a is a horizontal plane, whereas the upper surface 1c continuous to the peripheral side surface 1b includes an annular surface 2a of the annular identification layer 2 described later, and is slightly inclined like a gentle umbrella as a whole. Although formed, the upper surface 5a of the central portion 5 (in this embodiment, the cylindrical central portion 5) having the central hole of the substrate-like head 1 is a substantially flat surface.

  Thus, in the first embodiment, a slightly wide annular recess 7 is formed in a portion excluding the upper surface 5a of the cylindrical central portion 5 and the upper surface 6a of the peripheral end portion 6 of the substrate-like head 1 to identify the annular shape. The layer 2 is provided in close contact with the annular recess 7, and the annular surface 2 a of the annular identification layer 2 is slightly inclined on the upper surface 5 a that is a substantially flat surface of the cylindrical central portion 5 of the substrate-like head 1. It is continuous. The annular identification layer 2 of the first embodiment has an unnumbered inner peripheral side surface, an unnumbered outer peripheral side surface, an unnumbered annular bottom surface, and an annular surface 2a. The annular surface 2a has the cylindrical central portion. From the upper surface 5a as a substantially flat surface 5 to the upper surface 6a of the peripheral end portion 6, it continues in a gentle umbrella shape with a slight inclination. Accordingly, the thicknesses of the inner peripheral side surface and the outer peripheral side surface are matched with the thicknesses of the substantially flat surface of the cylindrical central portion 5 and the peripheral end portion 6, respectively.

  On the other hand, as shown in FIGS. 2 and 4, for example, the metal-made embedded shaft 3 is fixed to the substrate-like head portion 1 through an appropriate fixing means 11 such as a fixing pin or welding, From the center of the lower surface 1 a of the substrate-like head 1, a substantially cylindrical shape concentrically extends in the vertical direction as a shaft portion, and a helical screw portion 4 is formed on the peripheral side surface. The fixing means 11 of this embodiment includes a plurality of pins, a pair of notches formed perpendicular to the peripheral side surface of the upper end portion of the embedded shaft 3 into which these pins can be inserted, and a cylindrical central portion 5. A pair of notches formed in the inner peripheral surface is included.

The substrate-like head 1 has an inclined surface whose diameter is approximately 4.5 times the diameter of the helical screw portion 4 of the embedded shaft 3. It is a substantially flat substrate. Of course, the substantially flat substrate may be formed in, for example, a substantially flat trapezoidal shape, a flat generally dome shape, or the like without departing from the subject of the invention. Further, the thickness (vertical thickness) of the peripheral side surface 1b is approximately 1/14 of the lower surface 1a. Of course, the thickness of the peripheral side surface 1b is a matter that can be appropriately changed in design.

  Therefore, the characteristic items of the guide housing X will be described. The helical thread portion 4 has a thread having an angle α like a saw blade with an upward spiral surface 4a, and this thread has a turning function. Demonstrate. FIG. 2 shows an example of the thread angle α. In FIG. 2, for example, the thread angle α of the upward spiral surface 4a and the downward spiral surface 4b straddling the horizontal axis A indicated by the alternate long and short dash line is preferably set to 45 degrees to 60 degrees, more preferably 55 degrees. doing. The angle between the horizontal axis A and the upward spiral surface 4a is set to 7 degrees. Of course, the thread angle α is not limited to 55 degrees, but the thread angle α within a predetermined range may exhibit a returning function like a so-called fishing hook. Thereby, the buried shaft 3 does not easily come off from the flat surface F such as a road surface or a staircase.

  A plurality of engaging projections 50 provided on a dedicated tightening tool Y shown in FIG. 10 are respectively engaged with the peripheral end 6 of the substrate-shaped head 1 at a predetermined interval in the circumferential direction. Female engaging portion 12 (vertical hole or through hole). Thus, by using the electric tool Z such as the electric impact wrench shown in FIG. 10 and the exclusive tightening tool Y, the metal embedded shaft 3 of the guide housing X is easily screwed into the flat surface F such as the road surface or the stairs. Can do. Further, when an adhesive 52 is put in an attachment hole (for example, a pilot hole) 51 formed on any one of a road surface, a curbstone, and a staircase at the upper end portion of the peripheral side surface of the helical screw portion 4 of the embedded shaft 3. A receiving recess 13 for preventing looseness for receiving a part of the adhesive 52 is formed in a predetermined length in the axial direction. Thereby, at the time of screwing construction, a part of the adhesive 52 put into the mounting hole 51 of the flat surface F such as a road surface or a staircase enters the receiving recess 13 for preventing the loosening of the embedded shaft 3, and the entire adhesive 52 is When cured, it is possible to prevent loosening of the embedded shaft 3 due to vibration. Further, the identification layer 2 may be a rubber containing a phosphorescent particle body or a retroreflective cured resin body. Preferably, the identification layer 2 is a highly weatherable phosphorescent particle body coated with a polymer resin and an organic polymer having a honeycomb structure. And a cured resin body in which porous inorganic powder is mixed. Thereby, the visibility can be sufficiently ensured, and long-term use is possible.
