Japanese Patent No. 2581422 Japanese Patent No. 2675503

  However, in the conventional road sign pillars as described in Patent Document 1 and Patent Document 2, since the wiping member is attached to the attachment band at the upper end portion thereof, wiping is performed when an external force such as a strong impact is applied. The member is easy to break, the wiping effect is difficult to maintain over a long period of time, and the wiping members are entangled with each other, and the reflective sheet placed behind the wiping member in an unexpected state may not be visible, The wiping member arranged in a warm shape may cause a problem due to unpredictable swinging.

  The present invention has been made in view of the problems as described above, and provides a road sign post that can maintain a wiping effect over a long period of time and can prevent occurrence of problems due to unpredictable swinging of the wiping member. It is something to be done.

In order to achieve the above object, the present invention is configured as follows. That is, in the road sign pillar according to the present invention, a plurality of wiping members are disposed around the columnar main body at intervals on the left and right sides. A vertically long rectangular shape is formed by cutting into a vertically long strip shape except for the vicinity, and a vertically long rectangular gap is formed between adjacent wiping members, and near the upper end and the lower end. An upper support portion and a lower support portion are formed, respectively, and the upper support portion and the lower support portion are wound around the columnar body and fixed so that the wiping member is spaced from side to side around the columnar body. The wiping member is made swingable by adjusting the mounting interval between the upper support portion and the lower support portion .

  According to the road sign pillar according to the present invention, the wiping member is supported from above and below by being fixed at at least two points in the vertical direction, and stress is applied to at least two points when an external force such as a strong impact is applied to the wiping member. It becomes difficult to break up by being dispersed, and the wiping effect can be maintained over a long period of time. In addition, since the wiping member can be swung between two points, the range of rocking due to wind pressure or the like is predicted, and the occurrence of problems due to unpredictable rocking of the wiping member can be prevented.

  In addition, the two points are that once the wiping member is fixed to the upper support part and the lower support part wound around the columnar body, the wiping member is once attached to the upper support part and the lower support part. By attaching to a road sign post, workability can be improved, which is preferable.

  If the wiping member is formed by cutting an integral sheet-like body into a vertically long strip shape excluding the vicinity of the upper end and the vicinity of the lower end, the wiping member is wiped at intervals with a simple operation. The members can be arranged, and the interval between the wiping members can be reliably set by the cut width, which is preferable.

  According to the road sign pillar according to the present invention, the wiping member is supported from above and below by being fixed at at least two points in the vertical direction, and stress is applied to at least two points when an external force such as a strong impact is applied to the wiping member. It becomes difficult to break up by being dispersed, and the wiping effect can be maintained over a long period of time. In addition, since the wiping member can be swung between two points, the range of rocking due to wind pressure or the like is predicted, and the occurrence of problems due to unpredictable rocking of the wiping member can be prevented.

  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

  1 and 2 show an embodiment of a road sign post according to the present invention, and FIG. 1 is a front view of the road sign post. The road sign pillar 10 has a cylindrical pillar-shaped main body 2 standing upward from a base 3 fixed to the ground surface G. The columnar main body 2 is made of polyurethane resin and is bent by an external force such as a vehicle collision. It is. Around the columnar body 2, a plurality of wiping members 11 are provided at left and right intervals. The wiping member 11 is fixed by two points of an upper support part 12 and a lower support part 13 wound around the columnar body 2, and the upper support part 12 and the lower support part 13 are welded to the columnar body 2. It is attached. Above the columnar body 2, retroreflectors 4 that are reflective sheets are attached and attached in three stages, and retroreflectors R that are glass bead reflectors are attached to the base 3.

  Here, the wiping member 11 is fixed to the point P1 and the point P2 in the upper support part 12 and the lower support part 13, respectively, so that the cross-sectional area of the fixed part is doubled by fixing by two points. In addition, even when a strong external force is applied to the wiping member 11, the stress is not concentrated on one fixed portion and is distributed to two points so that the possibility that the fixed portion of the wiping member 11 is broken is reduced. Has been made. Even if the wiping member 11 is swingably attached so that the outer surface of the reflection sheet 4 or the columnar body 2 can be wiped and kept normal, the swingable range is limited. It is possible to prevent the visibility of the reflection sheet 4 from being impaired in an unexpected state such that the wiping members 11 are tangled with each other without causing unpredictable swinging.

  2A and 2B show the formation and attachment of the wiping member. FIG. 2A is a plan view showing a state at the time of formation, and FIG. 2B is a perspective view showing the state at the time of attachment. First, in (a), a flexible integral sheet-like body 1 made of a polyurethane resin is cut into a vertically long strip with an interval K, thereby forming a wiping member 11 with an interval K left and right. Here, the upper support portion 12 and the lower support portion 13 are formed in the vicinity of the upper end and in the vicinity of the lower end by cutting into a strip shape except for the vicinity of the upper end and the vicinity of the lower end. This sheet-like body 1 is attached to the road sign pillar 10 as shown in FIG. By simply winding the upper support portion 12 and the lower support portion 13 around the columnar main body 2 and attaching the upper support portion 12 and the lower support portion 13 to the columnar main body 2, a space K between the columnar main body 2 is easily left and right. The wiping member 11 can be arranged, and the interval K can be easily set as appropriate depending on the width of the strip.

  Further, in order to attach the wiping member 11 so as to be swingable between two points, by adjusting the attachment interval between the upper support portion 12 and the lower support portion 13, an appropriate tensioning condition for the wiping member 11 to swing is attached. It can be easily performed at the time of installation.

  The wiping member 11 is not particularly limited as long as the wiping member 11 can swing. However, a member having high hardness may damage or wear the columnar body 2 or the reflection sheet 4. In addition, a flexible synthetic resin material or cloth-like material having the same or low hardness as the reflective sheet 4 and high wear resistance is preferable. As the flexible synthetic resin material, a soft synthetic resin material is suitable, but an elastic synthetic resin material having a larger elastic deformation region is preferable, and examples of such an elastic synthetic resin material include polyurethane resins as described above, Natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, polyisobutylene resin, soft vinyl chloride resin, styrene-butadiene, polyolefin, polyester, polyvinyl chloride, polyurethane, polyamide, etc. Non-woven fabrics made from polyester-based synthetic resins and Tetron (registered trademark) used as tent fabrics. Polyester tree such as Fibers or the like and those very high and the tensile strength flexible that the acrylic resin fibers and fabrics, fibers can be used such as also suitably those coated with a synthetic resin cloth body and fabric.

  In addition, fixing the wiping member 11 is not limited to the configuration in which the upper support portion 12 and the lower support portion 13 are welded to the columnar body 2, and the wiping member 11 is directly welded, or the wiping member 11 and the columnar body 2 are fixed. And the base 3 are bonded by an adhesive means such as an adhesive, fastened by a fastening means such as a rivet or a screw, or between members constituting the road sign pillar 10, for example, between the pillar-shaped main body 2 and the base 3 or a pillar shape. It may be fixed by being sandwiched between the main body 2 and the upper end cap.

  Furthermore, the wiping member 11 may be provided with retroreflectivity. Retroreflective properties can be provided by sticking a reflective sheet to the outer surface of the wiping member 11 or attaching a retroreflective material such as glass beads to the outer surface of the wiping member 11.

  Further, the wiping member 11 may be provided only on the outer side of the reflection sheet 4 as shown in FIG. As shown in FIG. 1, by providing the entire columnar main body 2, not only the reflection sheet 4 but also the outer surface of the columnar main body 2 can be kept clean, but by providing only the outer side of the reflection sheet 4. The material for forming the wiping member 11 can be reduced and the mounting work can be facilitated, but the area receiving a strong external force such as being stepped on by a vehicle or the like can be reduced, and the wiping member 11 can be cut off. Can be made smaller.
