DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road signpost used for a center line of a road, a lane change line and a separation zone.

[0002]

2. Description of the Related Art Generally, this type of road signpost includes:
There are a fixed type buried on the road surface, a road surface standing type, and the like. As a material of the pillar body, a hollow molded product of a rubber material or a plastic material is used in addition to a metal hollow pipe. In the case where an elastic material is used as the material of the pillar body, there is a structure in which the pillar is flexibly bent in response to a collision of a passing vehicle or the like, absorbs an impact, and is restored to its original shape by elasticity. In addition, a fluorescent paint that is illuminated and reflected by the night illumination light of the vehicle is directly applied to the outer peripheral surface of the pillar main body, or a reflective sheet is provided by attaching a reflective sheet intermittently in the vertical direction of the pillar to drive. Some have improved the visibility of inside vehicle drivers and pedestrians.

[0003] In the case of such a conventional road sign post, in which the post main body is formed of an elastic hollow body and a reflection sheet is provided as a reflection sign band on the outer peripheral surface, the following problems remain. . That is, when the column main body is bent by elasticity by receiving an impact or an external pressure, such deformation has an adverse effect, and the reflection sheet attached to the outer peripheral surface cannot follow the deformation. As a result, the reflective sheet peels off from the pillar body,
Or, if a crack is generated, rainwater or dust enters through a gap formed between the reflective sheet at that portion and the outer peripheral surface of the column body, and the original function of the reflective sheet, which ensures visibility and safety, is lost at an early stage. There were many things.

[0004]

SUMMARY OF THE INVENTION The present invention has been improved to solve the above-mentioned problems, and has the advantage of utilizing the characteristic of elastic restoration. In addition, the reflection sheet is made to follow the deformation of the pillar body to prevent peeling. It is an object of the present invention to provide a road signpost capable of always maintaining the visibility and safety of a passing vehicle or a pedestrian.

[0005]

According to the present invention, there is provided a road sign pillar having a pillar body which is elastically deformable and is formed into a hollow cylindrical or solid rod shape, and which is fixed to a base at a base end, and an outer peripheral surface of the pillar body. In a road sign pillar provided with a reflective sheet continuously or intermittently attached to the pillar axis direction, the reflective sheet is formed so that it can be separated into a plurality of parts by elastic deformation of the pillar body. is there. As the reflection sheet, a slit or a perforation may be formed in the reflection member, and the elastic deformation of the pillar body may be absorbed by the slit or the perforation. In addition, the reflection sheet may be configured such that the reflection members are divided into small pieces and arranged with a required gap, and the elastic deformation of the column body is absorbed by the gap. These reflective sheets are
The surface may be covered with a transparent protective sheet.

[0006]

After setting the road surface, the reflection sheet is illuminated and reflected by the headlights of the vehicle running at night, and the reflection can be visually recognized by the driver. When elastic deformation occurs in the pillar body due to collision or contact by a traveling vehicle, etc., the reflection sheet absorbs the deformation by cutting or opening slits and gaps, preventing peeling and impairing the sign function, always good Visibility and safety can be maintained. Further, by covering the reflective member with a transparent protective sheet by overlapping, the prevention of peeling from the end surface of the reflective sheet is strengthened, which is effective for infiltration of rainwater and dust.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a road signpost according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an external appearance of a road sign pillar of an embodiment. A pillar body 10 of the road sign pillar is formed by hollow-molding an elastic material such as polyurethane rubber into a cylindrical shape. Is closed by a cap 11 to prevent infiltration of rainwater, dust, and mud. The lower portion is of a type that can be detachably or irremovably fixed by the pedestal 12 and can stand on a road. Since the pillar body 10 is hollow and cylindrically formed of an elastic material having high mechanical strength, such as polyurethane rubber, the impact force is not affected to some extent even when the pillar body 10 is temporarily deformed by a collision of a vehicle or the like. It absorbs and restores its original shape. Cap 1
1 and the pedestal 12 are also formed into a required shape with an elastic material such as polyurethane rubber of the same material as the column body 10.

On the outer peripheral surface of the pillar main body 10, a sign of a reflection area band by the reflection sheet 13 which is a main part of the present invention is provided at intervals over almost the entire length of the pillar height or only in the upper half. Is provided. The light of the illumination light of the vehicle running at night shines on the reflection sheet 13 and is reflected, so that not only the driver but also the pedestrian can clearly recognize the sign. Further, in the embodiment, a hollow cylindrical body is set as the column body 10, but a solid rod body or the like may be used in the sense that the object of the present invention can be achieved.

FIGS. 2 and 3 are a developed plan view and a side view of the reflection sheet 13 of the first embodiment. The reflection sheet 13 has a width dimension of, for example, about 50 mm and a length sufficient for the outer peripheral length of the pillar body 10. The release paper 14 having such a vertical and horizontal size is provided, and a reflection member 15 is removably attached to the surface of the release paper 14 with a pressure-sensitive adhesive. As shown in the figure, the reflecting member 15 is provided with slits 16 in a grid pattern at a vertical and horizontal pitch of, for example, 12 mm. Although the depth of the slit 16 due to the cut is about the thickness of the reflecting member 15, it is preferable that the cut does not reach the release paper 14 below in order to facilitate attachment to the pillar body 10. A perforation may be used instead of such a slit.

[0010] The road sign post to which such a reflection sheet is peeled off from the release paper and affixed, is installed on the road surface, and the post main body 10
The reflection sheet 13 provided on the outer peripheral surface of the vehicle is reflected by the headlights of the vehicle running at night, and is reflected, and this reflection can be visually recognized by a driver or a pedestrian.

FIG. 4 shows a state in which a passing vehicle or a pedestrian comes into contact with or collides with the pillar main body 10, and the pillar main body 10 is deformed such as bending or bending to such an extent that it can be elastically restored. That is, the pillar body 10 that has been bent or bent by receiving an impact or external pressure undergoes contraction on one side of the outer peripheral surface and deformation due to extension on the other side. In accordance with this deformation, the reflection sheet 13 also has a corresponding deformation. In the case of a conventional single reflecting sheet, the deformation of the pillar body 10 cannot be followed, and the reflecting sheet is peeled or cracked.

However, in the reflection sheet 13 of the embodiment,
As shown in the figure, the slit 16 on the extension side is cut or opened in response to the deformation of the pillar body 10, and a part of the reflecting member 15 is separated from each other (indicated by 15a, 15b in the figure). That is, the deformation (amount) due to the extension of the column body 10 is partially absorbed by cutting or opening the slit 16. Reflective member 1
The division of 5 is not enough to be visible,
The figures are emphasized to facilitate understanding. Therefore, since there is no peeling as seen from the whole of the reflection sheet 13, the sign function is not impaired.

If the reflection sheet 13 is formed of, for example, an elastic material having a certain degree of elasticity, the reflection member 15 is not completely separated from the slits 16 and the deformation of the column body 10 is prevented. It is also possible to absorb the deformation by the "opening" of the corresponding slit 16.

FIG. 5 shows the reflection sheet 17 of the second embodiment.
Is shown. In the reflecting sheet 17 of the second embodiment, only the slits 19 provided in the reflecting member 18 are parallel to the longitudinal direction of the sheet, that is, only the slits 19 extending in the circumferential direction of the column body 10 in the lateral direction are provided. However, unlike the first embodiment, they are not provided like vertical and horizontal lattice fringes. In this case, at least the vertical axis deformation from the column axis due to the elasticity of the column main body 10 is adapted. Also in this case, a perforation can be used instead of the slit.

The reflection sheet 17 of the second embodiment has a structure in which the surface of the reflection member 18 is further covered with a transparent protective sheet 21 with an adhesive layer 20, as shown in FIG. It is an enhanced protection. Reference numeral 22 in the figure denotes a release paper that is peeled off before sticking. Reflective sheet 1
In the sense of strengthening the surface protection of No. 7, it is also possible to attach a similar protective sheet to the surface of the reflective member 15 in the reflective sheet 13 of the first embodiment.

FIGS. 7 and 8 show a reflection sheet 23 according to a third embodiment. Reflection sheet 2 of the second embodiment
Reference numeral 3 denotes a deformation structure of the reflection sheet 17 of the second embodiment, and the slit 19 provided only in the horizontal direction.
, The reflecting member 24 is completely replaced with strips 24a, 24b,
And a gap 25 is formed between each of the strips 24a and 24b.
It is a structure partitioned by. That is, the deformation of the column main body 10 is positively absorbed by the gap 25 to improve the followability. The reflection sheet 23 is peeled off from the release paper 26 and attached to the outer peripheral surface of the pillar main body in such a gap state, and the surface of the reflection member 24 is covered with the protective sheet 28 via the adhesive layer 27 as in the second embodiment. Can be coated.

FIGS. 9 and 10 show a reflection sheet 30 according to a fourth embodiment. In the case of the reflection sheet 30 of the fourth embodiment, the protection sheet 2 of the second and third embodiments is used.
1 and 28 are of a large size. That is, a protective sheet 32 of a sufficient size in the vertical and horizontal directions is covered on the reflecting member 31 with the adhesive layer 33 interposed therebetween. By providing such a protection sheet 32, the reflection member 3
By completely enclosing 1, it is possible to block rainwater and dust from entering from the end face of the reflection member 31, and the function of the reflection sheet 30 can be further protected. Further, in the reflecting sheet 30 of the fourth embodiment, the reflecting member 31 is completely replaced with the strips 31a and 31b as in the third embodiment, instead of the slit.
And a gap 3 between each of the strips 31a and 31b.
The structure is partitioned by 4, and is attached to the outer peripheral surface of the pillar main body in such a state.
