Description

  The present invention relates to a reflective member for a protective fence post, and more particularly to a reflective member for a protective fence post that is fitted into a cap of a protective fence post and has excellent visibility.

  Conventionally, protective fences installed on roads, etc. are guards such as guard rails, guard pipes, guard cables, etc., which are erected at appropriate intervals, with pillars fitted with caps at the upper ends, and guard rails, guard pipes or guard cables attached between the pillars. It is comprised from the member.

  The protective fence is generally applied with white paint, but in recent years, the dark color of the tea system tends to be applied in consideration of the surrounding landscape. The dark-colored protective fence can be seen without problems during the day, but it is difficult to see at night and there is a risk of an accident. Even a protective fence with a white paint may be difficult to see at night.

  Therefore, Patent Document 1 discloses an example of a reflecting member that has a function of improving nighttime visibility and is fitted into a cap of a protective fence post. Hereinafter, this reflective member for protective fence support will be referred to as a conventional reflective member and will be described with reference to the drawings.

  8 is a front view showing a conventional reflecting member, FIG. 9 is a plan view showing the conventional reflecting member, FIG. 10 is a side view showing the conventional reflecting member, FIG. 11 is a bottom view showing the conventional reflecting member, and FIG. 9 is a cross-sectional view taken along line AA in FIG. 9, FIG. 13 is a cross-sectional view taken along line BB in FIG. 9, FIG. 14 is a cross-sectional view showing a conventional reflecting member fitted into a cap of a support, and FIG. It is sectional drawing which shows another conventional reflective member inserted by the cap of this.

  As shown in FIGS. 8 to 14, the conventional reflecting member includes a cylindrical resin reflecting member main body 3 fitted into a metal cap 2 (see FIG. 14) attached to the upper end portion of a column 1 made of a round steel pipe. A light reflecting material 5 comprising a plurality of (three in this example) claws 4 formed on the lower edge of the reflecting member main body 3 and a light reflecting tape attached to the side surface of the reflecting member main body 3. It is made up of.

  An abutting portion 6 that abuts on the outer surface of the cap 2 is formed on the upper portion of the reflecting member body 3. The contact part 6 is formed by projecting the upper part of the reflecting member main body 3 in a ring shape inside. Three notches 6a are formed in the contact portion 6 protruding in a ring shape inside the reflecting member body 3, and the claw 4 is formed on the lower edge of the reflecting member body 3 corresponding to the notches 6a. ing. The diameter (R1) of the circle (O) connecting the tip portions of the claws 4 before the reflection member body 3 is fitted is smaller than the diameter (R2) of the outer peripheral surface of the cap 2 (see FIGS. 9 and 14).

  As a result, when the reflecting member body 3 is fitted into the cap 2, the claw 4 spreads outward against the elastic force and returns to its original state by the elastic force after the fitting is completed. As a result of the claw 4 returning to its original state and the claw 4 coming into contact with the lower end surface of the cap 2, the reflecting member main body 3 will not come off the cap 2 even if a pulling force acts on the reflecting member main body 3 (FIG. 14).

  The contact portion 6 may be formed in a lid shape that covers the cap 2 as shown in FIG.

  In addition to the light reflecting tape, the light reflecting material 5 may be a light reflecting coating film formed by applying a light reflecting paint to the side surface of the reflecting member body 3.

  The conventional reflecting member configured as described above is fitted into the support cap as follows.

  The reflecting member body 3 is applied to the cap 2 and the reflecting member body 3 is pushed down with the palm of the hand. The pressing force at this time can be easily pressed down because the elastic force of the claw 4 is not large. When the reflecting member main body 3 is pushed down, the claw 4 descends along the side surface of the cap 2 while spreading outward against the elastic force. When the claw 4 passes through the cap 2, it returns to its original state by the elastic force. As a result, the claw 4 comes into contact with the lower end surface of the cap 2, so that the reflecting member body 3 is not detached from the cap 2 even if a pulling force acts on the reflecting member body 3.

  In this way, the conventional reflecting member is easily and reliably fitted into the cap of the protective fence post, and the reflecting member is not easily detached from the cap 2 even if a pulling force acts on the reflecting member.

  Here, the protective fence may be a guard rail, a guard pipe or a guard cable attached between the columns, or a fall prevention fence or a crossing prevention fence.

  Conventional reflecting members have the following advantages.

(1) Since the number of parts is only the reflecting member 3 for a support | pillar and the light reflecting material 5, a manufacturing cost will be cheap.
(2) Since it is what is fitted in the cap 2 of the support | pillar 1, high fitting intensity | strength is not required. As a result, it can be easily fitted into the cap 2 manually without using a tool such as a hammer.
(3) Since a high fitting strength is not required, there is no risk of losing the fitting to the cap 2 of the support column 1, and even if the fitting is lost, the fitting can be easily re-fitted.
(4) Since it does not require high strength, it has little impact on people even if it is damaged and scattered due to an accident such as a car colliding with a protective fence.
(5) Since it can be attached to a conventional cap, it can be attached to a guard fence post that has already been assembled.

  However, it is desired to develop a reflective member for a protective fence post having a higher light reflection effect than conventional reflective members.

  Accordingly, an object of the present invention is to provide a reflective member for a protective fence post having excellent visibility and having the advantages of the conventional reflective member as it is and having a higher light reflection effect.

  The present invention has been made to achieve the above object, and is characterized by the following.

  An embodiment of the reflecting member for a protective fence post according to the present invention will be described with reference to the drawings.

  1A and 1B are diagrams showing a protective member for a protective fence post according to the present invention, in which FIG. 1A is a plan view and FIG. 1B is a front view.

  As shown in FIG. 1, the reflecting member for a protective fence column of the present invention is a cylindrical resin reflecting member fitted in a metal cap 2 (see FIG. 14) attached to the upper end of a column 1 made of a round steel pipe. The main body 3, a plurality of (in this example, three) claws 4 (see FIGS. 8 and 9) formed inwardly on the lower edge of the reflective member main body 3, and affixed to the side surface of the reflective member main body 3 And a light reflecting material 5 made of a light reflecting tape.

  An abutting portion 6 formed in a quadrangular lid shape covering the outer surface of the cap 2 is formed on the upper portion of the reflecting member body 3. The light reflecting surface 7 is formed on each side of the contact portion 6.

  The diameter (R1) of the circle (O) connecting the tip portions of the claws 4 before the reflection member body 3 is fitted is smaller than the diameter (R2) of the outer peripheral surface of the cap 2 (see FIGS. 9 and 14).

  As a result, when the reflecting member body 3 is fitted into the cap 2, the claw 4 spreads outward against the elastic force and returns to its original state by the elastic force after the fitting is completed. As a result of the claw 4 returning to its original state and the claw 4 coming into contact with the lower end surface of the cap 2, the reflecting member main body 3 will not come off the cap 2 even if a pulling force acts on the reflecting member main body 3 (FIG. 14).

  2, the reflecting member for the protective fence column according to the present invention is configured such that the contact portion 6 is formed in a pentagonal lid shape and the light reflecting surface 7 is formed on each side of the contact portion 6. is there.

  As shown in FIG. 3, in another reflective member for a protective fence post according to the present invention, the contact portion 6 is formed in a hexagonal lid shape, and the light reflecting surface 7 is formed on each side of the contact portion 6. Is.

  As shown in FIG. 4, in another reflective member for a guard fence post according to the present invention, the contact portion 6 is formed in an octagonal lid shape, and the light reflecting surface 7 is formed on each side of the contact portion 6. Is.

  5 shows another reflective member for a guard fence support according to the present invention, in which the contact portion 6 is formed in a lid shape, and the light reflecting surface 7 is formed in a spiral shape in the contact portion 6. .

  FIG. 6 shows still another reflective member for a guard fence post according to the present invention, in which the contact portion 6 is formed in a lid shape and the light reflection surface 7 is formed on the entire surface of the contact portion 6.

  FIG. 7 shows another reflective member for a protective fence post according to the present invention, in which the contact portion 6 is formed in a lid shape and the light reflection surface 7 is formed in a radial shape on the contact portion 6.

  As described above, the examples shown in FIGS. 1 to 7 are all formed in a lid shape so that the contact portion 6 covers the outer surface of the cap 2 (see FIG. 15). Except for the reflecting member for the protective fence support shown, the contact portion 6 may be formed by projecting the upper part of the reflecting member body 3 in a ring shape inside.

  The light reflection effect can be further enhanced by attaching a light reflecting tape or applying a light reflecting agent to the light reflecting surface 7 formed on the contact portion 6 in the reflecting member for the protective fence support shown in FIGS. it can.

  Here, the reflected light that reflects the surface of the column with respect to the light source of a light such as a vehicle normally moves smoothly along the surface of the vehicle or the like because the column has a cylindrical shape. Accordingly, since the amount of reflected light is relatively constant, the effect of improving visibility is small.

  According to the present invention, since the light reflecting surface 7 is formed on the upper portion of the support column, the reflected light from the vehicle or the like has a difference in the amount of light between the position where it is reflected by the light reflecting surface 7 and the position where it is not reflected. This improves the visibility improvement effect.

  As described above, according to the present invention, the light reflecting surface 7 is formed on the abutting portion 6 to form the light reflecting tape attached to the side surface of the reflecting member main body 3 that the conventional reflecting member has. Since a higher light reflection effect is obtained by a synergistic effect with the reflection effect by the light reflecting material 5, the visibility can be further improved.

  Moreover, the light reflection effect can be further enhanced by attaching a light reflection tape to the light reflection surface or applying a light reflection agent.
