[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an apparatus for cleaning road signposts used for a center line, a lane change line, a separator, and the like of a road.

[0002]

2. Description of the Related Art In order to enhance the visibility of a driver of a vehicle running at night, a cleaning device for wiping off dirt due to exhaust gas and dust on a reflective sign band attached to a road sign pole by wind pressure of a vehicle or the like is known. For example, Japanese Patent Application Laid-Open No. 7-1
38920 and JP-A-6-299522.

[0003] This washing device is mounted on a road signpost,
And a holding member fixed to the road sign post, and a ribbon-shaped wiping member positioned on the reflection sign band of the road sign post and arranged around the road sign post and having an upper end held by the holding member. Then, the wiping member dances by wind pressure generated when an automobile or the like passes, rubs the reflective sign band of the road sign pillar, and removes dirt from the reflective sign band.

In these cleaning apparatuses, the holding member has a form of a cap, and the wiping member has an upper end fixed to the cap. The cap is put on the pole, and the pin is inserted into the top of the pole through the cap. As a result, the tip of the pin expands, and the removal of the cleaning device from the pole is prevented. Further, JP-A-6-299522
In addition to this type of cleaning device, Japanese Patent Application Laid-Open Publication No. H11-15064 also discloses a cleaning device that is formed of a cylinder and has only a wiping member having a plurality of ribbons formed by providing slits in the cylinder. The attachment is performed by fitting the wiping member to a pole of a road signpost and bonding the wiping member with a double-sided adhesive tape.

BEST MODE FOR CARRYING OUT THE INVENTION The cleaning device of the present invention can be mounted on a road sign post simply by pushing and expanding the holding member and fitting it on the road sign post, and a mechanism for mounting is specially required for the road sign post. Therefore, it can be easily and easily mounted on road signposts already set up on the road. When attached, it is immediately fixed to the road signpost by the elasticity of the holding member. Further, since no adhesive is required for mounting, even if there is a contact with a vehicle or the like immediately after mounting, it does not fall off.

In the present invention, the wiping member may be disposed on the inner peripheral surface of the holding member and fixed thereto, or may be disposed on the outer peripheral surface of the holding member and fixed thereto. And may be formed integrally. When the wiping member is arranged on the inner peripheral surface of the holding member and fixed thereto,
The wiping member may be further fixed to the road sign post with an adhesive, so that even if the holding member is detached by contact with a vehicle or the like, the cleaning function can be maintained. Further, the wiping member may have a reflective layer on the outer surface, so that even if the reflective sign band of the road sign pillar is peeled off by contact with a vehicle or the like,
The reflective sign strip on the wiping member reflects light from the car,
We do not lose function of road signpost so much. Further, the holding member may include means for pulling both sides of the cut portion to reduce the diameter of the holding member, whereby the mounting on the road sign pole can be performed more firmly, and the vehicle or the like can be mounted immediately after mounting. Even if there is contact, it is possible to more reliably prevent the device from falling off. The diameter reducing means may be formed, for example, by holes provided on both sides of the cutout portion of the holding member, and a stopper provided over these holes, or a pin and both ends arranged on both sides of the cutout portion of the holding member. Although it is constituted by a hook that is suspended, other configurations can be adopted.
