A slit 16 is formed on the reflection member 15, so that elastic deformation of the post main body 10 is adsorbed by the slit 16, or a reflection sheet is divided into thin pieces (24a, 24b-) and arranged at required spaces 25, so that elastic deformation of the post main body is absorbed by the spaces 25.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, as a road signpost of this type,
There are a fixed type embedded on the road surface, a road surface standing type, and the like, and as the material of the pillar body, in addition to a hollow pipe made of metal, a hollow molded product of a rubber material or a plastic material is used. There is a structure in which an elastic material is used as the material of the pillar main body, which flexibly flexes against a collision of a passing vehicle or the like, absorbs the shock, and then elastically restores the original shape. In addition, the outer surface of the pillar body is directly coated with fluorescent paint that is illuminated and reflected by the night illumination light of the vehicle, or a reflective sign strip that is affixed to the reflective sheet intermittently in the longitudinal direction of the pillar is used for running. Some have improved visibility for inside vehicle drivers and passersby.

By the way, in such a conventional road marking pillar, in the case where the pillar main body is formed of an elastic hollow body and a reflecting sheet is provided as a reflecting sign strip on the outer peripheral surface, the following problems remain. . That is, when the column main body is elastically bent under impact or 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 reflection sheet peels from the pillar body,
Or, if a crack is created, rainwater or dust will enter through the gap between the reflection sheet in that part and the outer peripheral surface of the column main body, and the original function of the reflection sheet to ensure visibility and safety will be lost early. There were many things.

[0004]

SUMMARY OF THE INVENTION The present invention has been improved in order to eliminate such a problem, takes advantage of the characteristic of elastic recovery, and further, by allowing the reflection sheet to follow the deformation of the column main body to prevent peeling, It is an object of the present invention to provide a road marking pillar that can maintain the visibility and safety of passing vehicles and passers-by at all times.

[0005]

A road sign post according to the present invention has an outer peripheral surface of a post main body in which a post main body which is elastically deformable and is formed into a hollow cylindrical shape or a solid rod shape is fixed to a pedestal at a base end. In a road sign post provided with a reflective sheet attached continuously or intermittently in the axial direction of the post, the reflective sheet is formed so that it can be separated into a plurality of parts by elastic deformation of the post body. is there. As the reflection sheet, a slit or perforation may be formed in the reflection member, and the elastic deformation of the column main body may be absorbed by the slit or perforation. Further, the reflection sheet may be configured such that the reflection members are divided into pieces and arranged with a required gap, and the elastic deformation of the column main body is absorbed by the gap. These reflective sheets are
It is also possible to cover the surface with a transparent protective sheet.

[0006]

After the road surface is installed, 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 the pillar body elastically deforms due to a collision or contact with a traveling vehicle, the reflection sheet absorbs the deformation by cutting or opening slits or gaps, so peeling is prevented and the marking function is not impaired. Visibility and safety can be maintained. Further, by overlapping the reflective member and covering it with a transparent protective sheet, 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 EMBODIMENT An embodiment of a road sign post according to the present invention will be described below with reference to the drawings. FIG. 1 is an external front view of a road sign post according to an embodiment. A pillar main body 10 of the road sign post is made of an elastic material such as polyurethane rubber and is hollowed into a tubular shape. Is closed by a cap 11 to prevent rainwater, dust, and mud from entering. The lower part is detachably or non-detachably fixed by the pedestal 12 and can stand on the road. Since the column main body 10 is made of an elastic material such as polyurethane rubber having a high mechanical strength and is hollowed into a cylindrical shape, the column main body 10 is capable of exerting an impact force to a certain extent even against a temporary deformation caused by a collision of a vehicle or the like. It is designed to absorb and restore its original shape. Cap 1
The base 1 and the pedestal 12 are also formed of an elastic material, such as polyurethane rubber, which is the same material as the pillar main body 10, into a required shape.

Further, on the outer peripheral surface of the pillar main body 10, a mark of a reflection area band formed by the reflection sheet 13 which is a main part of the present invention is provided over almost the entire length of the pillar or only in the upper half thereof. It is provided. Light from the illumination light of the vehicle traveling at night is reflected on the reflection sheet 13 to be reflected, so that not only the driver but also the passerby can clearly see it. Further, as the column main body 10, a hollow cylindrical body is set in the embodiment, but in the sense that the object of the present invention can be achieved, it may be a solid molded round bar or the like.

2 and 3 show a developed plan view and a side view of the reflection sheet 13 of the first embodiment. The reflection sheet 13 is prepared, for example, with a width dimension of 50 mm and a length sufficient for the outer peripheral length of the column main body 10. The release paper 14 having such vertical and horizontal sizes is provided, and the reflection member 15 is releasably 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 12 mm, for example. The depth of the slit 16 due to this cut is about the thickness of the reflection member 15, but it is desirable that the cut does not reach the release paper 14 below in order to facilitate the attachment to the column main body 10. Perforations may be used instead of such slits.

A road sign post having such a reflection sheet peeled off from a release paper and attached thereto is installed on the road surface of the post main body 10 after installation.
The reflection sheet 13 provided on the outer peripheral surface of the vehicle is illuminated and reflected by the headlight of a vehicle running at night, and the reflection can be visually recognized by a driver or a passerby.

FIG. 4 shows a state in which a passing vehicle or a pedestrian comes into contact with or collides with the pillar body 10 and the pillar body 10 is deformed such as bending or bending to the extent that elastic restoration is possible. That is, the column main body 10 that is bent or bent due to an impact or an external pressure is contracted on one side of the outer peripheral surface and deformed by extension on the other side. Reflection sheet 1 according to this deformation
3 also has a corresponding deformation. In the case of a conventional one-piece reflecting sheet, such deformation of the column main body 10 could not be followed, and peeling or cracking occurred in the reflecting sheet.

However, in the reflection sheet 13 of the embodiment,
As illustrated, the slit 16 on the extension side is cut or opened corresponding to the deformation of the column main body 10, and the reflecting members 15 are partly 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
Even if you say the division of 5, this is not visible,
The figures are emphasized to facilitate understanding. Therefore, since there is no peeling seen from the entire reflection sheet 13, the marking function is not impaired.

If the reflecting sheet 13 is formed of, for example, an elastic material having some elasticity, it is possible to deform the pillar body 10 without completely separating the reflecting member 15 from the slit 16. It is also possible to absorb the deformation by the degree of “opening” of the corresponding slit 16.

On the other hand, 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 on the reflecting member 18 are parallel to the sheet longitudinal direction, that is, only the slits 19 extending laterally in the circumferential direction of the column main body 10 are provided. However, unlike the first embodiment, it is not provided like vertical and horizontal lattice stripes. In this case, the elasticity of the column main body 10 minimizes the vertical axis deformation from the column axis. Even in this case, perforations can be used instead of the slits.

As shown in FIG. 6, the reflective sheet 17 of the second embodiment has a structure in which the surface of the reflective member 18 is further covered with a transparent protective sheet 21 with an adhesive layer 20. It is an enhanced protection. Reference numeral 22 in the figure is a release paper that is peeled off before attachment. Reflection sheet 1
From the viewpoint of strengthening the surface protection of No. 7, it is also possible to attach a similar protection sheet to the surface of the reflection member 15 of the reflection sheet 13 of the first embodiment.

7 and 8 show a reflecting sheet 23 of the third embodiment. The reflection sheet 2 of this second embodiment
Reference numeral 3 is also a modified structure of the reflection sheet 17 of the second embodiment, and the slit 19 provided only in the lateral direction.
Instead of the reflective member 24, the reflective member 24 is completely stripped.
In advance and subdivide each strip 24a, 24b between the gap 25
The structure is divided by. That is, the deformation of the column main body 10 is positively absorbed by the gap 25 to enhance the followability. The reflection sheet 23 is peeled off from the release paper 26, and is affixed to the outer peripheral surface of the column 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 covered with.

Furthermore, FIGS. 9 and 10 show a reflecting sheet 30 of the fourth embodiment. In the case of the reflection sheet 30 of the fourth embodiment, the protective sheet 2 of each of the second and third embodiments is used.
1, 28 are large size. That is, the reflection member 31 is covered with a protection sheet 32 having a sufficient size in the vertical and horizontal directions with the adhesive layer 33 interposed therebetween so as to overlap. By providing such a protection sheet 32, the reflection member 3
By completely wrapping 1 in, it is possible to block infiltration of rainwater and dust from the end surface of the reflecting member 31, and to further enhance the protection of the function of the reflecting sheet 30. Further, in the reflection sheet 30 of the fourth embodiment, instead of the slits in the reflection member 31, the reflection member 31 is completely stripped as in the case of the third embodiment 31a, 31b.
Are subdivided in advance, and a gap 3 is formed between each strip 31a, 31b.
The structure is divided by 4, and is attached to the outer peripheral surface of the column main body in such a state.

[0018]

As described above, when the road sign post according to the present invention is elastically deformed by the impact of a collision or contact of a passing vehicle after the road surface is installed, the post is elastically deformed by the reflection sheet so that the slits or gaps. Since it is absorbed by cutting or opening, peeling can be prevented, and there is an effect that good visibility and safety can always be maintained without impairing the labeling function.
