JP4112565B2 - A mat with ridges to warn automobiles of entering the road entry prohibited area - Google Patents

Description

  The present invention can be applied to a road where an automobile is traveling on a highway, a national road, or other roads where a traveling vehicle is out of the traveling lane due to, for example, falling asleep, on a road surface that is prohibited from traveling due to construction of the road surface. Further, the present invention relates to a tool for installing on a road surface that generates vibration and sound when the tire of the automobile rides and senses that the automobile has entered a prohibited travel area and causes an avoidance action.

  On highways, national roads, and other roads where automobiles travel, prohibited areas where traditionally working with driving lanes when working areas are occupied on the road surface for repairs and maintenance work such as cleaning. A color cone, such as a pylon that prohibits entry, is installed at the boundary of the vehicle, so that repair work can be performed safely and quickly without any obstacles. Nevertheless, there are many vehicles that depart from the driving lane due to a drowsy driving or the like, repel the color cone, and enter the work area occupied for construction. In such a case, there is nothing to protect oneself for the worker who is working in the work area, and the work is always forced to be in danger of life. For this reason, it was feared that it would always be a disaster.

  On the other hand, a few millimeter steps are intermittently provided on the pavement surface of the road on which the car is driven, alternately facing the road surface of the left and right tires of the vehicle and paving, thereby preventing the driver from falling asleep and driving downhill and curving. Means are being taken to alert the driver to the driver.

  Similarly, small rectangular fences made of metal, commonly called cat's eyes, are fixedly arranged on the center line of the road surface at regular intervals to prevent the traveling vehicle from protruding from the lane due to a curve or the like.

  By the way, considering the installation of the above color cones, in general, during construction of a road surface of an automobile road, in order to indicate the boundary between the prohibited travel area and the travel route on the road, there is an interval along the boundary. Position the color cone. This is to install a color cone with the expectation that a driver who visually recognizes the color cone will change the driving lane in advance or slightly shift the driving line to avoid the work area. For this reason, a red color cone with good visibility is used so that it can be seen from a distance, or a reflective tape is mounted on the color cone. Since the color cones are arranged at intervals, they are made of lightweight plastic material that is easy to carry so that they can be installed easily. For this reason, it is easy to flexibly change and secure the work area prohibited from traveling according to the progress of work on site, and the color cone is extremely convenient.

  However, if the color cone is simply placed at the boundary of the prohibited travel area at regular intervals, the driver may not be able to inadvertently see the color cone due to running asleep, etc. Is not necessarily an effective means. That is, the color cone is merely a means of visual attention and guidance. When a car actually intrudes and collides with the color cone, the color cone is lightweight, so that the impact and vibration applied to the vehicle from the color cone during the collision are very small. For this reason, there was a problem that drivers who were sleepy hardly noticed that they collided with the color cone. However, even if this is done, replacing a heavy object that can transmit the impact of a collision with a color cone may increase the danger. In other words, by repelling this heavy object in the event of a collision, the rebounded heavy object hits a third party, causing the third person to suffer more serious injury than if the color cone was repelled. There is a problem that is likely to have a positive impact. Therefore, there is a problem that the road manager does not permit the use of such heavy installations during road construction.

  In this way, by installing a color cone on the road and clearly indicating the work area, even if the driver of the car in motion is allowed to visually recognize the prohibited area, the driver who is driving a nap must be most alert However, there was no way to communicate that the color cone was installed, that is, that the work area was provided. For this reason, the work area is always next to danger, and there is still a problem that the risk reduction method by installing the color cone is not enough.

  In addition, the above means for laying a pavement zone by alternately providing a step of several millimeters on the road pavement surface facing the road surface of the left and right tires is certainly a means of alerting the driver physically. It can be said, however, that these were merely means of alerting to the sharply curved areas of the road surface by permanent pavement. Therefore, it was not a means for installing a road work site to temporarily secure an area. In addition, it is impossible to take flexible measures such as moving, re-installing and changing the means to arouse the danger zone in response to the progress of the road construction work, and the purpose of the installation is different. there were.

  Similarly, a metal rectangular rectangle known as a cat's eye is fixedly placed on the road center line at regular intervals, but if it passes over it, the driver may be alerted by vibration. Although the impact on the vehicle is large because it is a hard metal kite, the number of passenger cars with wheels equipped with low flatness tires has increased recently. And there was a possibility that the impact on the wheel was too great and hindered the subsequent running. This is also fixed and suitable for permanent installation on the road surface, but it is not suitable for temporary placement because it cannot easily remove installed ridges. Met.

  Furthermore, even if it can be easily installed, it has been requested that it can cope with road surface conditions such as rainy weather and does not pose a danger in place of the avoidance operation of the driver of the vehicle running.

  Therefore, the problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, and the course of the car changes while driving without being aware of the driver, such as snoozing driving, and the intrusion is prohibited. When entering a route area that is under construction, it is possible to inform an unconscious driver that the vehicle has entered, and to alert the driver and the vehicle safely and without danger. It is also possible to provide a retractable warning device that can be easily and quickly installed at an arbitrary place, which can be used even on a road surface or a puddle wet with rainwater.

The means of the present invention for solving the above-mentioned problem is that, in the invention of claim 1, the height is 1.8 to 2.5 mm and the width is 10 to 20 mm which can form a gap where water accumulated on the road surface can enter. The road is characterized by comprising a base of a wear-resistant rubber plate material comprising a plurality of non-slip protrusions 30-70 mm in length and spaced apart from each other by 30-70 mm and standing on the entire back surface. This is a mat with ridges for warning against vehicles that have entered the prohibited area .

By the way, when a car travels at a high speed on a paved road with a water film on the surface due to rain or the like, a dangerous state may occur in which neither the steering wheel nor the brake is effective. This state is called hydroplaning. This phenomenon is that when running on a paved road with a water film at high speed, there is no room for the water film to escape between the tread surface of the tire and the road surface, and it just slips over the lubricating oil, It is said that it occurs because neither running nor braking works.

Therefore, when the road surface of the car is wet with rain, etc., and a water film is formed between the ridged mat and the road surface, if the car rides on the ridged mat at high speed, it will be pushed by the momentum of the traveling vehicle. Therefore, it does not necessarily happen that the mat with the ridges slides on the road surface. If the hydroplaning phenomenon occurs on the road surface, the driver's control will not be effective and it will be very dangerous.

Therefore, in the invention of claim 1, as described above, a number of heights of 1.8 to 2.5 mm, a width of 10 to 20 mm, and a length of 30 to 70 mm are formed on the entire back surface of the base of the wear-resistant flexible rubber plate material. This is a mat with ridges, which are made up of small protrusions and have non-slip protrusions standing upright at intervals of 30 to 70 mm. By adopting this structure, a gap of 1.8 to 2.5 mm is formed between the mat with the ridge and the road surface. Therefore, even if the mat with ridges of the present invention is installed in a place where water has accumulated thinly due to rain or the like on the road surface, the mats with ridges are separated from the mat with ridges by a non-slip projection having a gap on the back surface. There is room for draining and escaping the water between them, and the entire mat with ridges does not slide out by keeping the road surface firmly in contact with the road surface at the small protrusion part of the anti-slip. When the traveling vehicle rides on the mat with the ribs of the present invention and the mat is heavy, the water accumulated in the gap between the back surface of the mat with the ribs and the paved surface is removed from the gap by the pressure received by the vehicle from above. It is only pushed out and drained, and the entire mat with the ridge is prevented from sliding due to the movement of the automobile. Therefore, even if the mat with a ridge of the present invention is installed on a road surface wet with water or the like, it is possible to accurately detect and warn of the intrusion of the automobile into the road entry prohibited area.

According to a second aspect of the present invention, the substrate has a width of 250 to 350 mm, a length of 4500 to 6000 mm, a thickness of 4 to 6 mm, a width of 18 to 23 mm, a height of 13 to 23 mm on the surface of the substrate, and the substrate. 2. The road entry prohibition according to claim 1, wherein a plurality of protrusions having the same length as the horizontal width of the base are erected at intervals of 200 to 300 mm in the longitudinal direction of the base. It is a mat with ridges for warning against vehicles that have entered the area.

As described above, this mat has a vibration imparting band composed of a plurality of protrusions that generate vibration and noise, so that a driver who is looking away or asleep while driving feels vibration and vibration sound. Attention can be drawn, and avoidance operations such as braking and steering can be taken. In addition, by using the mat of the present invention in combination, the number of color cones to be erected can be reduced as compared with the prior art, and accidents due to splashing of the color cone can be reduced. Furthermore, since it is made of a wear-resistant flexible rubber plate having a size and shape that can be carried and installed, it can be rolled up at the time of transportation and quickly spread on site. In this way, installation, movement, and withdrawal can be performed very easily, so that a flexible response can be made according to the progress of work.

According to the first aspect of the present invention, in road construction and road maintenance work for repairing a road by restricting the road width of a national road or highway on which a vehicle travels, When the mat with ridges of the present invention is laid in front or around, the non-slip of the small protrusions provided on the back surface of the mat always keeps contact with the road surface, so even when laid on wet road surfaces, the ridges of the present invention Attached mats are extremely slippery and have excellent effects that can be used safely regardless of road conditions, such as being less likely to cause hydroplaning.

Further , by adopting the means of claim 2, by laying the mat with the ridge of the means of claim 2 in front of or around the work area, it can be experienced by a driver of an automobile that has accidentally entered the work area due to falling asleep. Therefore, it is possible to feel vibration and vibration sound and to let the driver notice that the vehicle has entered accidentally, and the mat with a protrusion of the present invention has an excellent effect. Furthermore, when the vehicle travels on the mat with a ridge of the present invention, the vibration and noise are clearly transmitted to the surroundings, so that not only the driver of the car that has entered but also the surrounding work There is an effect that it is possible to easily ventilate a person who has entered the vehicle accidentally.

In addition, since the mat with ridges can be laid, moved, and withdrawn very easily, the mat with ridges of the present invention has excellent effects, such as being able to secure a safe work area quickly. is there.

  The best mode for carrying out the present invention will be described below with reference to the drawings. As shown in FIG. 4, on a highway, a national road, or other road on which automobiles are traveling, a passenger car 22 that is traveling due to, for example, falling asleep on a road surface 1 that is a travel-prohibited area 2 during construction or the like is in a travel lane 3. A mat with warning ridges installed on the road surface 1 that is used to make the driver sense that the passenger car 22 has entered the prohibited travel zone 2 and to evade when he / she accidentally enters the car. 5.

  As shown in FIG. 1, the mat 5 with a warning ridge of the present invention is a wear-resistant flexible rubber plate material 6. The wear-resistant flexible rubber plate 6 is composed of a base 7 having a width 8 of 250 to 350 mm, a length 9 of 4500 to 6000 mm, and a thickness 10 of 4 to 6 mm. On the surface 11 of the base 7, a plurality of ridges 12 having a length 13 that is the same as the lateral width 8 of the base 7 are 250 to 350 mm, a width 14 is 18 to 23 mm, and a height 15 is 13 to 23 mm. Have. The plurality of ridges 12 are erected at intervals of 200 to 300 mm in the longitudinal direction of the base 7.

  The base 7 made of the wear-resistant rubber plate material 6 of the warning ridged mat 5 can form a gap 18 into which water on the road surface 1 can enter when water is accumulated on the road surface 1 due to rain or the like. The back surface of the base 7 with a plurality of non-slip protrusions 17 each having a height of 1.8 to 2.5 mm, a width of 10 to 20 mm, and a length of 30 to 70 mm, spaced at an appropriate interval, for example, 50 mm. 18 is erected on the entire surface. FIG. 2 is a perspective view of the mat 5 with protrusions as viewed from the front side and (b) from the back side. FIG. 3 shows a side view of the state in which the ridged mat 5 is wound up.

  A specific use mode of the present invention will be described. FIG. 4 shows a case where one lane on the left lane 3 of the road on one side is restricted to travel on the left lane 3 as a restricted area 21 for work, and only one lane on the right overtaking lane 19 is guided. Indicates. In this case, the example in which the mat 5 with the ridge of the present invention is installed in the restricted area 21 of the traveling lane 3 is shown. When the passenger car 27 is traveling in the direction of the arrow on the left lane 3 in FIG. 4, the passenger car 22 is guided by the color cone 4 and crosses the white line 20, which is the boundary of the vehicle lane, and passes the overtaking lane 19 on the right side. It will run. The left lane regulation area 21 is a work area where repair work and cleaning work are carried out. On the front side of the restricted area 21, that is, in the lower left of the drawing, the color cone 4 is installed obliquely so as to block the left lane 3 for vehicle guidance, and inside the white line 20 until the restricted area 21 ends. The color cones 4 are arranged at intervals. As shown in FIG. 4, the mat 5 with protrusions according to the present invention is continuously arranged linearly inside the color cone 4 aligned inside the white line 20.

  By the way, when the lane is regulated by the color cone 4 or the standing sign and the traveling vehicle is guided to the overtaking lane 19 side, the driver who visually recognizes the instruction by the color cone 4 or the standing sign changes the traveling line and follows the guidance. However, even if the vehicle is guided by the color cone 4 or the standing sign and is traveling on the overtaking lane 19, it may be looked away during that time, or may fall asleep. In such a case, the vehicle often flutters gently and meanders, and gradually cuts into the restricted area 21 along a loose line. Therefore, if the mats with ridges 5 according to the present invention are arranged in a line along the white line 20 from one end portion on the start side of the restriction area 21, one wheel of the vehicle that has been gently cut into the mat 5 with ridges. The ridges 12 of the mat 5 with ridges ride and vibrate and generate noise. In this case, since the approach angle to the restricted area 21 is shallow, the time for the tires to ride on the mat 5 with the ridges is long, and the vibration is repeatedly generated with a rattling noise. The driver can be clearly alerted.

  In order to confirm the effect of the present invention, the interval 16 between the protrusions 12 of the mat 5 with protrusions is set to 200 mm and 250 mm, for example, 300 mm shown in FIG. 1, and the height of the protrusions 12 is 15 mm and 20 mm. While changing to the two types, the car was run on the mat 5 with the protrusions, and the vibration and noise inside the vehicle and the vibration and noise outside the vehicle were measured. For automobiles, we chose a 3000cc class luxury car as a passenger car and a 10-ton car as a truck. In this running, the mat 5 with the ridges is turned up by being dragged by the tires of the car, or how much vibration and noise can be perceived by the driver or the worker working around the car. The experiment was conducted with a passenger car traveling at a speed of 45 kg / hr and a truck traveling at a speed of 50 kg / hr.

  For measurement of noise and vibration in the car, NA-20 (with verification) and Level Recorder LR-20 as normal sound level meters are used, and VM-51 (Rating) from Rion Corporation as vibration level meters. Attached) and a noise seismic intensity level processor SV-76. In the case of a passenger car, noise and vibration in the vehicle compartment were measured on the seat at the rear of the vehicle, and in the case of a truck, the noise and vibration were measured on an air suspension and a seat cushion. On the other hand, the noise and vibration around the outside of the vehicle were measured by placing each of the above sound level meters at a point closer to the shoulder of the road by 3.5 meters from the installation position of the mat 5 with the ridges. In this running test, the mat 5 with the ridges did not turn up with the rotating tires of both the passenger car and the truck.

  Next, a result of measurement of noise and vibration in a running experiment of a passenger car and a truck when the mat 5 with the ridge is installed and when the mat with the ridge 5 is not shown with a dotted line in the drawing. Indicates. First, as shown in the upper right end of FIG. 5, the noise and vibration in the passenger car is provided with protrusions having a distance of 300 mm and a height of 20 mm as shown by 300-20. The vibration was 98 dB at Max. On the other hand, in the case of noise and vibration outside the passenger car, as shown by 200-20 at the upper right end of FIG. 6, when the projections with intervals of 200 mm and height of 20 mm are provided, the noise is Max at 104 dB, and the vibration is Max. It was 51 dB. As shown by 250-20 at the upper right end of FIG. 7, in the case of providing protrusions with an interval of 250 mm and a height of 20 mm, the noise was 103 dB for Max and the vibration was 53 dB for Max. As shown by 300-20 at the upper right end of FIG. 8, the noise was 102 dB at Max and the vibration was 53 dB at Max, with protrusions having an interval of 300 mm and a height of 20 mm. As a result, in the case of a passenger car, vibration was detected rather than noise in the car. On the other hand, outside the vehicle, the noise was 104 dB, but the vibration was as low as 54 dB, and the noise was felt very loud. However, there was no significant difference due to the spacing of the ridges. Further, in the idling when the mat shown by the dotted line was not installed, the noise was as low as 86 dB in MAX.

  Next, the noise and vibration in the truck's car is shown by the solid line of the first test in the truck's car, as shown by 300-20 at the upper right end of FIG. 9, provided with protrusions with an interval of 300mm and a height of 20mm. With the mat of the present invention shown, the noise was 77 dB for Max, the vibration was 100 dB for Max, the noise for the second test was 78 dB for Max, and the vibration was 102 dB for Max. However, no particular difference was felt in the truck's car as compared to the case of the idling without the mat shown by the dotted line. This is because, in the case of trucks, it was installed on the air suspension, and as a result, noise and vibration were not as different as passenger cars. However, even in the case of a truck, the vibration transmitted to the handle can be felt clearly and strongly, and the danger could be detected by installing the mat of the present invention.

  Furthermore, the noise and vibration outside the vehicle of the truck, as shown by 200-15 at the upper right end of FIG. 10, is provided with protrusions with a spacing of 200 mm and a height of 15 mm, the noise is Max at 105 dB, and the vibration is Max. It was 63 dB. As shown by 200-20 at the upper right end of FIG. 11, in the case of providing protrusions with an interval of 200 mm and a height of 20 mm, the noise was Max at 106 dB and the vibration was Max at 64 dB. As shown by 250-15 in the upper right part of FIG. 12, the noise was Max at 105 dB and the vibration was Max at 66 dB in the case where the protrusions with the interval of 250 mm and the height of 15 mm were provided. As shown by reference numeral 250-20 at the upper right end of FIG. 13, in the case of providing protrusions with an interval of 200 mm and a height of 20 mm, the noise was 106 dB for Max and the vibration was 66 dB for Max. As shown by 300-15 in the upper right part of FIG. 14, the noise was 103 dB at Max and the vibration was 67 dB at Max, with protrusions having an interval of 300 mm and a height of 15 mm. As shown by 300-20 in the upper right end of FIG. 15, the noise was 106 dB at Max and the vibration was 69 dB at Max, with protrusions having an interval of 300 mm and a height of 20 mm. As a result, it was possible to feel the noise very strongly outside the vehicle. However, the difference due to the interval between the protrusions was hardly recognized in the case of the track. On the other hand, in the case of idling where no mats indicated by dotted lines are installed, the noise is 98 dB in MAX and the vibration is 62 dB in MAX, both of which are slightly lower than those in which the mat is installed. The installation effect was felt enough.
