By the way, in Patent Document 1, an embedded visibility pattern is arranged at an excavation site on a road surface. However, there is a possibility that the driver may accidentally miss this visibility pattern.
Moreover, in the said patent document 2, although the vehicle tire is made to vibrate when the tire of a vehicle rides on the marking material piece formed in the convex shape on the road, for example, a driver passes this place frequently. In this case, there is a problem that the user gets used to the vibration generated in the marking material piece, and the alerting is neglected.

Such alerting on the road is particularly important for a vehicle that is going through a railroad crossing from the viewpoint of preventing accidents.
For example, in order to prevent a train accident from occurring, it is necessary for the driver to surely recognize that the train is approaching a railroad crossing. However, in the technology disclosed in Patent Documents 1 and 2 described above, the driver When there was an accident, there was a problem that the danger situation that the train was approaching could not be recognized with certainty.

  The present invention has been made in view of the above-described circumstances, and allows a vehicle that is going to cross a railroad crossing to recognize a dangerous situation that a train is approaching. The present invention provides a crossing danger recognition device that can reliably prevent a railroad crossing.

In order to solve the above problems, the present invention proposes the following means.
And in order to achieve the said objective, this invention has a danger alerting means which alert | reports danger with respect to the vehicle which is provided on the road before a level crossing, and passes the upper surface, When the train approaches, it has a movable part that reciprocates between a protruding position that protrudes upward and a retracted position that retreats downward.

  According to the present invention, there is provided the danger notifying means for notifying the vehicle which is provided on the road before the railroad crossing and passes through the upper surface thereof, and the danger notifying means protrudes upward. The vehicle has a movable part that reciprocates between a position and a retreat position that retreats downward. Therefore, when the train approaches, the vehicle is lifted from the ground at the “protrusion position”. An operation of lowering the vehicle lifted at the “position” onto the ground can be performed. That is, when the movable part of the danger notification means reciprocates between the “protruding position” and the “retracting position” when approaching the train, it is possible to vibrate the vehicle located above the rattle. Such vibration of the vehicle allows the driver in the vehicle to reliably recognize that the train is approaching the railroad crossing, so that a railway accident that may occur due to the driver's inadvertent mistake is obviated. It becomes possible to prevent.

Further, various types of movable forms can be realized by providing a plurality of sets of the movable parts and further connecting the movable parts to each other by a support member or by providing a large-diameter disk-like support member on each movable part. be able to.
In addition, by arranging the movable part on a road in front of the railroad crossing within a certain range according to the length and width of the vehicle, a vehicle approaching the railroad crossing can be approached with respect to a vehicle passing there. It is possible to reliably notify.
Further, by positioning the danger notification means in front of the crossing and behind the road sign indicating the crossing, the driver first visually recognizes the presence of the crossing by the road sign. Later, by reciprocating the movable part of the danger notification means, the driver can be made to recognize the train approaching condition.

It is a schematic structure which shows the operation example in case the movable part of a danger alerting | reporting means exists in a "projection position." It is a schematic block diagram which shows the operation example in case the movable part of the danger alerting | reporting means shown in FIG. 1 exists in a "retreat position." It is a figure which shows the operation example which made the movable part in the front area of a danger alerting | reporting means the "retraction position", and made the movable part in a rear area the "projection position". It is a figure which shows the operation example which made the movable part in the front area | region of a danger notification means the "protrusion position", and made the movable part in a rear area | region the "retraction position." It is a top view which shows the example which provided the large diameter discoid support member in the upper end of the up-and-down moving member of a movable part. It is a top view which shows the example which connected the several vertical movement member of the movable part with the common support member.

An embodiment of the present invention will be described with reference to FIGS.
1 and 2 are schematic configuration diagrams of the danger recognition device. In these drawings, reference numeral F denotes a crossing, and reference D denotes a danger recognition region on the road surface located on the front side of the crossing F. FIG.

The danger recognition area D on the road surface is provided with danger notification means 1 for notifying the vehicle R passing the upper surface of the danger.
The danger notification means 1 includes a plurality of movable parts 2 that reciprocate upward or downward when a train approaches.

Each movable part 2 is composed of a hydraulic cylinder 10 as a drive source and a vertical movement member 11 installed at the tip of the piston of the hydraulic cylinder 10, and protrudes upward as shown in FIG. It reciprocates between the “protruding position” and the “retracted position” retracting downward as shown in FIG.
Note that the reciprocation between the “projection position” and the “retraction position” in the movable portion 2 is performed in conjunction with the operation of the alarm device 20 installed at the level crossing F. That is, in the control means indicated by reference numeral 30, on the condition that the train 21 approaches and the railroad crossing F alarm 20 operates, as shown in FIG. 1 and FIG. The hydraulic cylinder 10 is driven so as to reciprocate upward or downward. Alternatively, on the condition of receiving a signal transmitted from a detection device that detects that the train 21 is approaching the railroad crossing F, as shown in FIG. 1 and FIG. The hydraulic cylinder 10 may be driven so as to reciprocate downward.

  Further, the reciprocating motion between the “projecting position” and the “retracted position” in the movable portion 2 does not cause trouble in traveling of the vehicle R, and the approach of the train 21 is reliably transmitted to the driver of the vehicle R. As described above, an optimum cycle is set for the control means 30. For example, the vertical movement member 11 of the movable portion 2 is moved up and down with a short period with respect to the control means 30 to vibrate the vehicle R located on the movable portion 2 violently and more reliably to the driver. It is also possible to call attention.

Further, the danger recognition area D of the danger notification means 1 is set not only according to the length and width of the vehicle R but also according to the traffic volume of the crossing F.
Further, the danger notification means 1 is disposed in front of the level crossing F and behind the road sign 22 indicating the level crossing F. Thereby, first, the road sign 22 is made to visually recognize the presence of the crossing F to the driver, and then the train is approaching the driver by the reciprocating movement of the movable part 2 of the danger notification means 1. Can be recognized sensuously.

As described above in detail, according to the danger recognition device shown in the present embodiment, it is dangerous for the vehicle R that is provided on the danger recognition area D on the road surface before the railroad crossing F and passes through the upper surface thereof. The risk notification means 1 includes a movable part 2 that reciprocates between a “protrusion position” that protrudes upward and a “retraction position” that retreats downward. When the train 21 approaches, the vehicle R is lifted from the ground at the “protruding position” (FIG. 1) and is lifted at the “retracting position” (FIG. 2). The operation of lowering R onto the ground can be performed.
That is, when the movable part 2 of the danger notification means 1 reciprocates between the “protruding position” and the “retracting position” when approaching the train, the vehicle R located on the upper part can vibrate rattlingly. By virtue of such vibration of the vehicle R, it is possible for the driver in the vehicle to reliably recognize the approach of the train to the railroad crossing F and to prevent a railway accident that may occur due to a driver's inadvertent mistake. It becomes.
