Description

  The present invention relates to a warning tool that is temporarily laid on a road and that gives a vibration when passing a vehicle by providing an appropriate level difference to alert a driver about road work ahead of the traveling direction.

  Conventional alerting tools are generally used in the form of strips and arranged in several rows at appropriate intervals so that the longitudinal direction is perpendicular to the traveling direction of the road. However, since such a conventional warning tool is used in a situation where a large number of vehicles pass over it, a force along the traveling direction is applied each time the vehicle passes, and as a result, the arrangement position However, there was a disadvantage that would shift greatly.

  In order to eliminate such inconvenience, there has been proposed a device for fixing the position by providing a bolt embedding hole in an alerting tool formed in a strip shape and driving a restraining member such as a bolt or a nail directly into the road. (See Patent Document 1).

  Moreover, what was made to adhere to a road surface by providing a recessed part in the back surface side of the alerting tool formed in strip | belt-plate shape, and arrange | positioning an adhesive material in the recessed part (refer patent document 2). .

Japanese Patent No. 2638133 No. 07-50406

  However, although the alerting tool described in Patent Document 1 can securely fix the alerting tool to the road surface, an operation to drive the restraint member into the road is required. Therefore, there is a problem that the time and labor loss is very large, and the worker who performs installation / removal work on the road is exposed to danger for a long time.

  Moreover, in the alerting device described in Patent Document 2, it is necessary to remove dust on the road in advance before installation in order to increase the adhesive force, which is troublesome. Further, when the road surface is wet due to rain or the like, there is a problem that the adhesive force of the adhesive material is greatly reduced and the effect of the adhesive material is not exhibited.

  Furthermore, the warning tool formed in the shape of a strip is only once when the vehicle rides on the warning tool and the vibration is given only once. In order to evoke, it is necessary to arrange a plurality of rows at appropriate intervals, and there is a disadvantage that the installation work increases accordingly.

  For this reason, the present invention can maintain the ground contact force even on wet road surfaces, and even if it is installed only in one place, the vehicle driver is subjected to multiple vibrations. It is intended to provide an alerting tool that can give sufficient attention and can be easily installed and removed.

  The alert tool according to the present invention is an alert tool that alerts the driver of a vehicle by laying on a road to form a step, and the alert tool has an insertion hole in a radial direction. The annular member and a connecting member formed by inserting each of the through holes of the annular member to connect the annular members adjacent to each other when the plurality of annular members are connected to each other. The member is formed on a band-shaped portion that passes through the insertion holes of the annular members adjacent to each other, a flange portion formed on one end surface in the longitudinal direction of the band-shaped portion, and another end surface in the longitudinal direction of the band-shaped portion. And a stopper that can be attached to and detached from the fitting portion.

  In the alert device according to the present invention, the grounding force can be maintained even on a wet road surface, and even if it is installed only in one place, the driver of the vehicle is subjected to multiple vibrations. It is possible to give sufficient attention, and furthermore, installation work and removal work become easy.

FIG. 6 is a perspective view showing a usage state of the alerting tool according to Embodiment 1 of the present invention.

  In FIG. 1, 1 is an alerting tool. The alerting tool 1 is configured by connecting a plurality of annular members 2 to each other by a connecting member 3. As shown in FIG. 6, the alerting tool 1 is used by being laid on a road 12. That is, a step is formed on the road 12 by the alerting tool 1 and used to alert the driver of the vehicle 13. Therefore, the alerting tool 1 according to the first embodiment is colored in a conspicuous color such as yellow so as to obtain a visual alerting effect in addition to the alerting effect caused by vibration generated when the vehicle 13 passes. It becomes.

  As shown in FIG. 2, the annular member 2 includes a first concentric ring 4a, a second concentric ring 4b, and a third concentric ring 4c that are concentrically spaced from each other. The three concentric rings 4c are connected to each other by connecting portions 5 provided at a plurality of locations. The first concentric ring 4a to the third concentric ring 4c are formed with a first insertion hole 6a, a second insertion hole 6b, and a third insertion hole 6c that are inserted in the radial direction, and the first insertion hole 6a to the first insertion hole 6a to the first concentric ring 4a. The three insertion holes 6 c are communicated to form the insertion hole 6. Note that six insertion holes 6 are formed at equal intervals along the circumferential direction of the annular member 2.

  A hard synthetic resin having a small repulsive force and a high grounding force is suitable for the material of the annular member 2 in the first embodiment, but other materials may be used. In addition, the annular member 2 has a triple configuration of the first concentric ring 4a to the third concentric ring 4c, but is not limited to a triple configuration, and has a single, double, or quadruple multiple configuration. Also good.

  Hereinafter, the structure of the connecting member 3 in Embodiment 1 will be described.

  As shown in FIG. 3, the connecting member 3 includes an insertion portion 3 a formed in a band shape, and a stopper 3 b for preventing the removal after the insertion portion 3 a is inserted through the insertion hole 6.

  The insertion portion 3a includes a band-like portion 31 that is inserted through the insertion hole 6, a flange portion 32 that is in contact with the side surface of the first concentric ring 4a of the annular member 2 on the side where the insertion portion 3a is inserted in the adjacent annular member 2. It is comprised from fitting hole 33a, 33b (henceforth the fitting hole 33) provided in the edge part vicinity which opposes the edge part in which the flange part 32 was provided.

  On the other hand, the stopper 3b includes a base material portion (planar portion) 36 facing the belt-like portion 31, and projections 37a formed on one plane of the base material portion 36 and inserted into fitting holes 33a and 33b, respectively. 37 b (hereinafter, referred to as a protrusion 37), a wall surface 38 provided on the surface opposite to the plane on which the protrusion 37 of the base material 36 is formed, and also formed on the surface. The taper part 39 is comprised.

  Hereinafter, the usage method of the connection member 3 in this Embodiment 1 is demonstrated.

  As shown in FIG. 1, the alerting tool 1 includes a plurality of annular members 2 connected to each other. The plurality of annular members 2 are connected and fixed by a connecting member 3. Therefore, in order to connect and fix the adjacent annular members 2 to each other, the insertion portion 3a is inserted into the insertion hole 6 in the arrow A direction as shown in FIG. At this time, the insertion portion 3a may be inserted into the insertion hole 6 until the flange portion 32 contacts the side surface of the first concentric ring 4a.

  If the insertion part 3a is inserted into the insertion hole 6 until the flange part 32 abuts on the side surface of the first concentric ring 4a, the fitting hole 33 formed in the belt-like part 31 will protrude from the insertion hole 6. Therefore, in this state, the protrusion 37 of the stopper 3b may be inserted into the fitting hole 33.

  In the connecting member 3 according to the first embodiment, the fitting hole 33 and the projection 37 are designed to be press-fitted to each other so as to suppress the disconnection. In addition, the protrusion 37 is inserted into the fitting hole 33 while the taper 39 is engaged with the insertion hole 6 (see FIG. 5). Accordingly, it is possible to reliably prevent the protrusion 37 from coming off from the fitting hole 33.

  Further, the connecting member 3 according to the first embodiment is designed so that the wall surface portion 38 abuts against the side surface of the first concentric ring 4a in a state where the insertion portion 3a and the stopper 3b are engaged. Therefore, it is possible to suppress backlash of the annular members 2 connected to each other.

  In addition, although the connection member 3 in this Embodiment 1 is a product made from a synthetic resin, material is not limited.

  In the first embodiment, as described above, the annular member 2 is connected in two rows by the connecting member 3 as shown in FIG. At this time, since the insertion holes 6 are provided at equal intervals along the circumferential direction in the annular member 2, that is, at intervals of 60 degrees when viewed from the center of the annular member 2, the annular members 2 are arranged in a plurality of rows. Even if comprised in this way, each annular member 2 can be connected with all the adjacent annular members 2. Needless to say, by repeating such a connecting operation, the annular member 2 can be connected in two or more rows, or can be used in only one row.

  The alerting tool 1 configured by connecting the annular members 2 is laid so that the longitudinal direction is perpendicular to the traveling direction of the road 12 as shown in FIG. The installation location is in front of the traveling direction in which road work is being performed, and is positioned so that the driver of the vehicle 13 cautioned by the alerting tool 1 can decelerate with sufficient margin. It is desirable to do.

  Since the ring-shaped member 2 is formed in a circular shape in the first embodiment, the alerting tool 1 is a tire compared to the conventional belt-plate-like alerting tool regardless of where the tire of the vehicle 13 rides. Since the contact area with the vehicle becomes smaller, the displacement due to the passage of the vehicle 13 is suppressed. In addition, since the force applied when the vehicle is traveling is uniformly distributed, not only can the shift be suppressed, but even if the shift occurs, the road moves in the direction along the traveling direction of the vehicle 13. The shift in the direction perpendicular to the traveling direction of 12 is suppressed. Furthermore, since the annular members 2 are in contact with each other at a point, it is possible to suppress wear due to friction between the annular members 2 caused by vibrations during vehicle passage.

  Moreover, since the alerting tool 1 according to the first embodiment is formed by the first concentric ring 4a to the third concentric ring 4c in which the annular member 2 is connected with a space therebetween, the first concentric ring is formed when the vehicle passes. Since the ring 4a to the third concentric ring 4c are in contact with the tire independently, and the first concentric ring 4a to the third concentric ring 4c are independently contacted with the road 12, the grounding force can be improved.

  As described above, the alerting tool 1 according to the first embodiment has a significantly improved grounding force as compared with the conventional one, so that the displacement due to the passage of the vehicle 13 is greatly suppressed without using a restraining member or an adhesive material. It can be used even when the road surface is wet due to rain or on unpaved roads.

  Further, in the alert device 1 according to the first embodiment, the tire of the vehicle 13 is grounded once in the annular member 2 because the annular member 2 is configured in an annular shape. Therefore, two steps are provided for each annular member 2, and vibrations are given twice each time the vehicle 13 passes through one annular member 2. Therefore, even when the alerting tool 1 is installed only in one place, it is possible to alert the driver sufficiently.

  Moreover, since the alerting tool 1 in this Embodiment 1 is comprised by the annular member 2 being connected by the connection member 3, it adjusts length so that it may adapt to the road width in an installation place each time. I can do it. Further, when a part of the annular member 2 is worn or damaged, only the annular member 2 can be replaced.

  Moreover, since the connection member in this Embodiment 1 can easily connect or disassemble the annular member 2 by detaching the stopper 3b, convenience is improved. That is, when the warning device 1 is withdrawn from the road, the stopper 3b is removed and the connection of the annular member 2 is released, so that the device can be transported without being bulky and can be stored (stored) in a small space. I can do it.
