Abstract

PROBLEM TO BE SOLVED: To provide a pedestrian crossing preventive fence, by which the violent crossing of a pedestrian is prevented effectively on a road, in which a section between a traffic lane and an on-coming lane is narrow, while the danger of a secondary disaster is reduced even when a car or the like contacts or collides. SOLUTION: Columnar bodies 1 composed of a synthetic resin are disposed upright at proper intervals along the road direction among traffic lanes A and opposing lanes B, to call pedestrians attention and drivers attension while the violent crossing of the pedestrians is prevented because a section among the traffic lanes A and the opposing lanes B is interrupted by fence beams 3 by installing the fence beams 3 comprising the synthetic resin among the columnar bodies 1. Even when the cars or the like comes into contact with these columnar bodies and fence beams, the fence beams 3 and the columnar bodies 1 are not damaged and are restored because they consist of the synthetic resin. When the cars or the like collide, the fence beams 3 and the columnar bodies 1 are damaged easily, and impulses given to the cars are reduced. The damage of the car and the danger of a secondary disaster are also lowered because the fence beams 3 and the columnar bodies 1 scattered on the opposing lanes are damaged easily even when the cars trample down them.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestrian crossing prevention fence installed along a road between a traveling lane and an oncoming lane.

[0002]

2. Description of the Related Art Conventionally, on a road where a relatively wide lane can be taken between a traveling lane and an oncoming lane, a guardrail or a retaining wall is installed between the traveling lane and the oncoming lane, or a tree or the like is planted. A so-called median strip is provided to promote safe driving of the vehicle and prevent pedestrians from crossing. In addition, on roads where the distance between the traveling lane and the oncoming lane cannot be made large and a median strip cannot be provided, a road marking such as a center line is simply provided between the traveling lane and the oncoming lane. Only.

[0003]

However, on such a road where such a median strip is not provided and only a road marking such as a center line is provided, a case in which a pedestrian forcibly tries to cross the road may lead to an accident. Many. Particularly on a road with two lanes on one side (four lanes on the other side), the traversing distance is extremely long, and it is extremely dangerous for a pedestrian to cross. Further, when a road between such a traveling lane and an oncoming lane is narrow, when a strong metal guardrail or the like is provided between the traveling lane and the oncoming lane to prevent pedestrians from crossing, If a running vehicle comes into contact with or collides with such a guardrail, etc., if there is a collision or collision, there is a risk of not only damage to the running vehicle but also secondary damage to oncoming vehicles etc. due to scattering of the damaged guardrail etc. .

Accordingly, the present invention solves the above-mentioned problems and effectively prevents pedestrians from crossing over a narrow road between a traveling lane and an oncoming lane. Even so, the aim is to provide a pedestrian crossing prevention fence that reduces the risk of secondary disasters.

[0005]

In order to achieve the above object, the present invention has the following arrangement. That is, in the pedestrian-crossing prevention fence according to the present invention, columns made of synthetic resin are erected at appropriate intervals along the road direction between the traveling lane and the oncoming lane, and synthetic resin is interposed between the columns. A fence beam is attached.

[0006] By installing the pedestrian crossing prevention fence according to the present invention along the road direction between the traveling lane and the oncoming lane, the fence beam blocks the lane between the traveling lane and the oncoming lane. It alerts pedestrians and traveling vehicles, and prevents pedestrians from crossing unnecessarily. Also, since the fence beam and the columnar body to which this fence beam is attached are both made of synthetic resin, even if a vehicle etc. comes in contact with them, they can be restored without being damaged, and if a collision occurs, they can be easily fenced. Beams and pillars are damaged, and there is little impact on the vehicle.Furthermore, even if the vehicle steps on the fence beam or pillar scattered on the oncoming lane, it is easily damaged, and there is a risk of vehicle damage and secondary disaster Is also reduced.

In the present invention, the mounting structure of the fence beam to the column is not particularly limited, but both ends of the fence beam are mounted to the column through a synthetic resin mounting member, and in the unlikely event that a vehicle or the like is used. In the event of collision with these fence beams or pillars, if the fence beam and the pillars are easily separated from the mounting member, the impact given to the vehicle at the time of vehicle collision will be reduced, The risk of secondary disasters is also effectively reduced.

Further, the fence beam is constituted by a connection body comprising two or more fence beam units connected to each other between the columnar bodies, and if a vehicle or the like collides with the fence beam, the fence beam is disassembled from the connection portion. If the vehicle is easily damaged, the impact given to the vehicle at the time of a vehicle collision is reduced, and the risk of vehicle damage and secondary disaster is also effectively reduced.

The pillar may be erected by burying its lower part directly between the traveling lane and the oncoming lane, but may be provided between the traveling lane and the oncoming lane along the road direction. If road studs are provided and the pillars are erected through the road studs, the road studs can also alert the traveling vehicle and pedestrians, and the pillars and fence beams have been removed. In this case, only road tacks can be used.

Also, on the outer surface of the fence beam and / or the columnar body,
If a reflective sign is formed to reflect light from a vehicle headlight or the like so that the sign shines brightly, the traveling vehicle and the pedestrian can be alerted.

[0011]

Next, an embodiment of the present invention will be specifically described with reference to the drawings. First, FIG. 1 is a perspective view showing an embodiment of a pedestrian crossing prevention fence according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a sectional view.

In the drawings, A is a driving lane, B is an oncoming lane, and P is the present invention provided between the running lane A and the oncoming lane B, for example, on the center line S along the center line S. A pedestrian crossing prevention fence 1 is a pillar that constitutes the pedestrian crossing prevention fence P, 2 is a road stud on which the pillar 1 is erected, and 3 is a fence beam attached to the pillar 1.

The columnar body 1 is formed of a hollow synthetic resin, and is provided with a reflective portion 11 having a reflective material wound around the outer periphery thereof. It is made to reflect light and shine brightly.

The road stud 2 has a trapezoidal shape provided with a reflecting portion 21 made of glass beads or the like on the side surface. An anchor bolt 22 or the like is provided between the traveling lane A and the opposite lane B along the road direction. Are provided at appropriate intervals on the road surface, and the pillars 1 are attached to the respective road studs 2 so that the pillars 1 extend along the road direction between the traveling lane A and the oncoming lane B. It is designed to be erected at an interval from each other.

The fence beam 3 is attached between the pillars 1 erected through the road studs 2 and is made of synthetic resin. In addition, it is attached to the pillars 1 to reduce the weight. The inside is hollow so that it does not bend, and a sign 31 having reflectivity is provided on the outer surface thereof by sticking a reflecting material or the like, and the sign 31 is a headlight of a vehicle. It is made to shine brightly by reflecting light such as.

The fence beam 3 may be in the form of a string or a thin pipe. However, in these cases, visibility to a pedestrian is poor, and the effect of preventing crossing is low. Accordingly, if the vertical width of the fence beam 3 is made large, preferably, for example, about 100 mm or more, the visibility is improved in combination with the reflective marker portion 31, and the crossing prevention effect is further improved.

The fence beam 3 has a pipe-shaped mounting member 4 made of synthetic resin penetrating the upper part of the columnar body 1 and the mounting member 4 is inserted into the end of the fence beam 3. Locked by a rivet 5 made of synthetic resin,
It is attached to the columnar body 1. The mounting member 4 is formed of synthetic resin, and the end of the fence beam 3 is locked to the mounting member 4 by a rivet 5 made of synthetic resin. In the event of a collision, the fence beam 3 and the columnar body 1 are easily separated from the mounting member 4 to reduce the impact given to the vehicle at the time of collision of the vehicle, etc. This is to further reduce the risk of

Further, as in the present embodiment, the fence beam 3 comprises two fence beam units 3a connected to each other between the columnar bodies 1.
In the event that a vehicle or the like collides with the fence beam 3, it is preferable that the fence beam 3 be disassembled from the connection portion and easily broken. As described above, the fence beam 3 is constituted by a connected body composed of two or more fence beam units 3a, and when the fence beam 3 is disassembled from the connection portion and easily damaged at the time of a vehicle collision, an impact given to the vehicle is reduced. The risk of vehicle damage and secondary disasters is also effectively reduced.

In this embodiment, the connecting member 6 is inserted between the opposite ends of the two fence beam units 3a, and the ends and the connecting member 6 are locked by the rivets 7, Although the two fence beam units 3a are connected, if both the connecting member 6 and the rivet 7 are formed of a synthetic resin as in the case of the mounting member 4, the connecting portion at the time of collision of a vehicle or the like can be obtained. It is preferable because it is easily broken.

The synthetic resin forming the columnar body 1, the fence beam 3, the mounting member 4 and the connecting member 6 may be of any type. It is preferable to use an olefin-based synthetic resin such as polyethylene or polypropylene, which is easily damaged, emits no toxic gas during waste combustion, and is easy to recycle even when recycled, When the resilience of the resin is more effectively provided, it is preferable to use an elastic synthetic resin such as a urethane resin or various elastomers.

[0021]

By installing the pedestrian crossing prevention fence according to the present invention along the road direction between the traveling lane and the oncoming lane, the space between the traveling lane and the oncoming lane is blocked by the fence beam. This alerts pedestrians and traveling vehicles, and prevents pedestrians from crossing the road. Also, since the fence beam and the columnar body to which this fence beam is attached are both made of synthetic resin, even if a vehicle etc. comes in contact with them, they can be restored without being damaged, and if a collision occurs, they can be easily fenced. Beams and pillars are damaged, and there is little impact on the vehicle.Furthermore, even if the vehicle steps on the fence beam or pillar scattered on the oncoming lane, it is easily damaged, and there is a risk of vehicle damage and secondary disaster Is also reduced.
