Next, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the present invention. The bodily sensation mat 1 of the first embodiment is made of hard rubber, has a rectangular flat plate shape, and has a substantially mountain-shaped vertical cross section perpendicular to the longitudinal direction. 2 are provided in a strip shape in the longitudinal direction. The end closer to the approaching vehicle is defined as the front end 3 of the step having a constant thickness with the front side as the front side. The inclination angle of the rear slope with respect to the convex portion 2 is a gentle angle, and the end portion is formed as a rear end portion 4 having a smaller step than the front side.

Further, a plurality of grooves 5 are formed on the back side of the mat 1 in the longitudinal direction. Also, at one end in the longitudinal direction of the sensation mat 1, two circular convex portions 6 are projected as male connecting portions to which the same size and the same size sensation mat 1 can be connected, and the other end portion. Has a female connection,
Two circular recesses 7 are provided.

Next, use of the mat 1 will be described. As shown in FIG. 3, the sensation mat according to the present invention is provided with a margin on a side where a vehicle 11 is expected to dive, that is, on a side facing the vehicle 11 in a construction site 10 surrounded by a protective fence 9 for the construction site. Three of the two connected 1s are arranged. At this time, the front end 3 is disposed outside, that is, in such a manner that it comes into contact with the vehicle first. The connection is performed by fitting the circular convex portion 6 as the male connection portion of the other mat 1 to the circular concave portion 7 as the female connection portion of the mat 1. In this manner, the sensation mat 1 is arranged on the side of the construction site 10 facing the vehicle 11.

Even if the vehicle 11 driven by the driver who has fallen asleep approaches, the bodily sensation mat 1 of the present invention is disposed on the side of the construction site protective fence facing the vehicle. It collides with the front end 3 of the sensation mat 1, and the impact is transmitted to the driver through the tire. Thereafter, the tire of the vehicle 11 rides on such a front end portion 3 and collides with the convex portion 2 which is the second obstacle. At this time, a second impact is given to the driver. Thereafter, the vehicle 11 goes down a gentle slope. Usually, when the vehicle 11 rides on such a body mat and lands over the top, a loud noise is generated due to the impact. However, as described above, the body mat of the present invention has a gentle slope. In addition, since it is made of hard rubber, such a sound is hardly generated, and even if it is generated, it is easily absorbed.

As described above, the vehicle 11 receives two impacts when traveling on the sensation mat 1 of the present invention, and these impacts are transmitted to the driver via the tires, and even if the driver is dozing, By waking up, the driver can wake up and step on the brake or turn the steering wheel to avoid jumping into the construction site. Further, in this case, the bodily sensation mat is installed with a margin from the construction site, so that the driver does not step on a sudden steering wheel or a sudden brake, and is safe. Further, the sensation mat 1 of the present invention is impacted from the vehicle 11 as described above,
It can be stomped on and run over, but because it has a plurality of grooves 5 in the longitudinal direction on the back side, the degree of adhesion to the road surface 8 is good,
Further, even if the road surface 8 has some unevenness, the road surface 8 is hardly displaced.

FIG. 4 shows a second embodiment of the present invention. The bodily sensation mat 21 in the second embodiment is substantially the same as the first embodiment in that the plane is a rectangular plate, but the vertical cross section perpendicular to the longitudinal direction is different. The structure of the second embodiment is closer to a mountain shape than that of the first embodiment,
In addition, the top is not a convex portion having a constant width but a sharp ridge. One of the slopes on the front side of the top is a short steep slope, and the front end 23 is a large step. Further, the rear end 24 of the other slope that is the rear side is not a step, but a long gentle slope,
It is connected to the road surface 25 as it is.

When the mat 21 of the second embodiment is used, the vehicle that has traveled first collides with the front end 23 and receives an impact. And the front end 2
Ride 3 and continue to the top 22. Then, when landing beyond the top 22, there is a second impact. After this top 22, the road is downhill. Then, the rear end portion 24 is not gradually connected to the road surface 25 but gently. Therefore, in the second embodiment, the impact is applied to the front end 2.
It is given to the driver twice at the points 3 and 22. Also, the tire lands on the gentle slope after passing over the top 22 and the impact noise is small because these are hard rubber.

FIG. 5 shows a third embodiment of the present invention. The bodily sensation mat 31 of the third embodiment is substantially the same as the first and second embodiments in that the flat surface is a rectangular plate. The vertical cross-section perpendicular to the direction is different. In the third embodiment, the step portion of the front end portion 33 is a top portion, and when the front end portion 33 is exceeded, a long gentle downhill is formed, and the rear end portion 34 is smoothly formed on the road surface 36. What is connected.

When the sensation mat 31 according to the third embodiment is used, the vehicle that first travels collides with the front end 33 and receives an impact. However, the front end 3
After climbing 3 and passing this front end 33, the rest is downhill. Therefore, unlike the first and second embodiments, the impact given to the driver is only once. Also, the tire lands on the gentle slope after passing the front end 33, and since these are hard rubber, the impact noise is small.

As described above, according to the sensation mat of the present invention,
Since the vehicle is impacted at least once when traveling on the mat, even if the driver falls asleep, the driver wakes up and can avoid jumping into the construction site. Further, after passing over the convex portion 2 or the like at the top of these mats, the mats are smoothly inclined, so that the bodily sensation mat 1 cannot be wound up by the rotation of the running tire. Furthermore, since the surface of these mats is inclined on both the front end side and the rear end side, water does not accumulate even in rainy weather, and the vehicle does not slip even when running on the mat. It is safe. Further, since these sensation mats are of a connection type, they can be conveniently set in various ways according to the road width and other conditions.

The bodily sensation mat according to the present invention alerts a dozing driver by an impact when traveling on the mat, and a driver who is driving normally drives on the mat according to the present invention. Even though the driver feels an impact, the driver feels impact, but the sensory mat is flat, so there is no other inconvenience, for example, no danger of hindering driving, and the driver is safe.

In the above-described embodiment, a circular uneven portion is employed as a connecting portion for connecting a plurality of such mats, and the mats are connected in the longitudinal direction. Is not limited to this structure. Also, when installing this sensation mat outside the construction site,
Not only one row but also two or three rows and a plurality of rows may be installed in parallel.

[0021]

According to the first aspect of the present invention, even if a vehicle driven by a dozing driver approaches a construction site, the sensation mat of the present invention is installed around the construction site. Therefore, if the driver runs on the sensation mat, the driver receives an impact. The driver wakes up from sleep and steps on the brake or turns the steering wheel to prevent the driver from jumping into the construction site. In addition, after the top of the sensation mats, etc., the slopes are smooth, so that the sensation mats cannot be wound up by the rotation of the running tire. Furthermore, since the surface of these mats is inclined on both the front end side and the rear end side, water does not accumulate even in rainy weather, and the vehicle does not slip even when running on the mat. It is safe.
In addition, it is a plate of a simple shape, it does not take up space at the construction site when not in use, it can be cleared immediately after construction is completed, and it is a gentle slope that the tire lands on the top etc. So the impact sound is small.

According to the second and third aspects of the present invention, there are two places where a shock is applied to the driver.
As compared with the first aspect of the present invention, the impact can be reliably applied to the driver, which is effective.

According to the fourth aspect of the present invention, the bodily sensation mat collides with the vehicle, is stomped on, and rides over. However, since the mat has a plurality of grooves in the longitudinal direction on the back side, the degree of adhesion to the road surface is good. In addition, even if there is some unevenness on the road surface, it is hard to shift from the road surface and can be stably installed on the road.
