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 the material of the pillar body, in addition to a metal hollow pipe, a hollow molded product of rubber or plastic material, a solid molded product, etc. are used. . It is known that a luminous paint is directly applied to the outer peripheral surface of the pillar body so as to be illuminated and reflected by a nighttime illumination light of the vehicle, or a reflective sheet is intermittently attached in a vertical direction of the pillar to form a sign portion. Have been.

[0003] By the way, with such conventional road signposts, dirt due to wind and rain dust is hard to resist.
As means for cleaning the dirt, means such as wiping with the help of a human operator, or using a cleaning machine is used. For this reason, not only is the cost increased, but also there are restrictions such as performing work under traffic regulation and the like. Moreover,
Particularly in places with heavy traffic, it is not possible to frequently perform traffic regulation, and even if it is performed, work in a short time is required.
In addition, there is a problem that dirt is generated at an early stage even when washing is performed in a place where traffic is heavy or inside a tunnel.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem, and the wiping device is shaken by utilizing the natural wind pressure, the wind pressure when passing through a car, the water pressure of a sprinkler, and the like. It is an object of the present invention to provide a road sign pillar which can be moved or bent so as to come into contact with a sign part such as a reflection sheet or the like and automatically remove stains on the surface.

[0005]

According to the present invention, there is provided a road sign pole provided with a wiping device for covering a sign part from outside, the sign part being provided on a pillar body. In the wiping device, a headband-shaped mounting belt is detachably provided at an upper end portion of the column main body, and a number of linear wiping materials are locked on the entire circumference of the mounting belt at the upper end and droop along the outer peripheral surface of the column main body. The linear wiping member is configured to be able to come into contact with the marker portion of the pillar body by irregular swinging.

[0006]

[Function] After the road surface is installed, a large number of linear wiping members are swung or flexed irregularly by natural wind or wind pressure when the vehicle passes, and the operation causes the outer peripheral surface of the pillar body and the outer peripheral surface of the sign portion. Wipe off dirt and dust from the surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a road signpost according to the present invention. FIG. 1 is a front perspective view of an embodiment of the present invention. Pillar body 10 of road sign pillar
Is formed into a hollow shape by a rubber material, a plastic material, or a metal, and is fixed to a road surface below the figure by a pedestal 11 or installed so as to be detachable. The pillar body 10 extends over the entire vertical length up to the upper end portion or the lower end portion, and a reflection area band made of a luminous paint as a sign portion, or a reflection sheet 12 as shown in the drawing.
Are provided at intervals, and the light of the illumination light of the vehicle running at night is reflected so that the driver can visually recognize the light. The top end of the pillar body 10 is closed by a lid member 13 to prevent rainwater dust from entering the pillar. The column body 10 having such a structure may be considered to be a known one already put into practical use. A wiping device 20 for removing dirt such as dust is attached to the position of each reflection sheet 12 of the pillar main body 10.

The wiping device 20 has a length sufficient to cover each of the reflection sheets 12 provided on the pillar body 10 from the outside, and a large number of hairs hanging uniformly from the upper end of the entire circumference of the pillar to the lower end of the pillar. It is mainly composed of a linear wiping member 22 made of a material or the like. The upper end portion 23 of the linear wiping member 22 is engaged with a headband-shaped mounting belt 21 having the outer periphery wrapped around the upper portion of the column main body 10, and the lower end has a free-end-like appearance as if it were a blind. . In addition to the mounting belt 21, a hook-and-loop fastener (loop / hook fastener), a double-sided adhesive tape, or the like can be used. In the embodiment, the upper end portion 23 of the linear wiping member 22 is bonded to the mounting belt 22 with an adhesive, and the mounting belt 21 can be replaced by a new or old replacement.

As the material of the linear wiping member 22, animal and plant hair, chemical fiber twisted yarn, and the like can be freely selected in addition to synthetic fiber hair such as nylon and polypropylene. Among these materials, in particular, synthetic fiber bristles and twisted yarns are suitable as the linear wiping member 22 in terms of durability and cleanability. The wire diameter of the linear wiping member 22 can be freely selected within a range of about 0.01 to 5 mm. In the embodiment, a wire having a wire diameter of 0.3 mm is used.

[0010] Of course, the linear wiping material 22
As a condition, it is necessary to have a rigidity enough to wipe off dirt such as dust and mud attached to the outer peripheral surface of the reflection sheet 12 in addition to the flexibility of swinging by wind pressure or the like.
Also, the density of the mat-like linear wiping members 22 due to the spacing, the number, and the thickness of the mat-like wiping members 22 should not hinder the visibility of the sign portion such as the reflection sheet 12. Further, it is conceivable to use an adhesive tape in place of the mounting belt 21.
It is not preferable to completely adhere from the surface of No. 0 so as not to peel or difficult to peel.

In this embodiment, with the above construction, after the road surface is installed, each of the linear wiping members 22 flexes and swings irregularly due to natural wind, wind pressure when passing through the vehicle, and the like, and such irregular swinging occurs. The movement is synergistic and the pillar body 10 and the reflection sheet 12
, And can effectively wipe off dust and mud attached to the surface.

In the embodiment, the structure in which the linear wiping member 22 is locked to the mounting belt 22 at the upper end 23 and the lower end 24 is a free end has been described. However, the mounting belt 2
A structure similar to 2 is provided at the lower end of the pillar body 10 and the lower end 24 of the linear wiping member 22, that is, the upper and lower ends 23, 24 are respectively engaged with the mounting belts 22, 22. However, in this case, the linear wiping member 22 is not
By locking the members 3 and 24, the individual linear wiping members 22 can be flexed such as rocking without being hindered by the movement of the linear wiping member 22 due to the wind pressure or the like, and come into contact with the surfaces of the column body 10 and the reflection sheet 12. It is necessary to lock and restrain the upper and lower ends 23 and 24 to the extent possible.

[0013]

As described above, the road signpost according to the present invention uses the natural wind and the wind pressure when passing through the vehicle to randomly swing or bend each of the hanging linear wiping members. , Pillar body and sign section (reflective sheet)
Dust and mud attached to the surface of the
As in the past, various costs including labor costs associated with a periodic cleaning operation can be saved, and the trouble of traffic control for work can be eliminated.
