Description

  The present invention relates to an antiglare plate, and more particularly to an antiglare device provided with a ventilation hole through which wind and rain can blow.

Conventionally, it is known that an anti-glare device is attached to a central separation zone that divides a plurality of lanes on a general road or an expressway via a guard rail or a spacing member that separates the guard rail. The anti-glare device includes an anti-glare plate that prevents the headlight of an oncoming vehicle traveling in the other lane from entering the eyes of the driver of the vehicle traveling in one lane. By blocking or reducing such light, the driver is prevented from being dazzled by glare.
As a specific configuration of the anti-glare plate, a single rubber plate or the like completely blocks the light of the oncoming vehicle, and a thin net is stretched on the frame-like frame member to diffract light. There is a configuration that reduces the amount of light that enters the driver's eyes.

JP 2003-147730 A JP 2000-282419 A

However, the installation location of the anti-glare device is often a place that is constantly exposed to wind and rain such as general roads and highways, and when the anti-glare plate having the former configuration is adopted, the light is completely transmitted. Although it can be shut off, it will receive wind and rain on its front and back surfaces, and the deterioration of the front and back surfaces and the looseness of the mounting members will proceed rapidly, and when mounting to guard members and spacing members separating guard rails, In order to cope with wind and rain, it is necessary to use many mounting members and metal fittings, and there is a drawback that the mounting operation itself includes many steps.
In addition, when the anti-glare plate having the latter configuration is adopted, wind and rain pass through the net, so it is superior to the former configuration in terms of deterioration of the front and back surfaces, attachment parts, and increase in the installation process. However, since it is not a configuration that completely blocks light, but a configuration that reduces to the last, there is a disadvantage that it is inferior to the former configuration from the viewpoint of preventing glare caused by glare.

  Therefore, in order to solve the above-mentioned problems, the present invention can surely prevent glare caused by glare, which is the main function of the anti-glare device, and can be attached to an object such as a guard rail with very few mounting parts and mounting steps. An object of the present invention is to provide an anti-glare plate and an anti-glare device that can be attached to an object.

In order to solve the above-mentioned problem, as a first configuration according to the present invention, an antiglare plate that is attached between a plurality of lanes, and a ventilation hole that penetrates the front and back surfaces of the antiglare plate and a ventilation hole are formed. It was set as the structure which has the light-shielding piece which stands | starts up from an edge.
According to this configuration, since wind and rain blow through the ventilation holes that penetrate the front and back surfaces of the antiglare plate, the wind pressure received by the antiglare plate itself can be reduced.
Moreover, the light which an oncoming vehicle emits can be interrupted | blocked by the light-shielding piece which stands up from the edge part which forms a ventilation hole, and the glare prevention by glare can be performed reliably.

Further, as a second configuration, the light shielding piece extends from the edge on one lane side to the edge on the other lane side at the edge forming the ventilation hole.
According to this configuration, since the light shielding piece is inclined and extended from the edge on one lane side to the edge on the other lane side at the edge forming the ventilation hole, a part of the ventilation hole is formed by the light shielding piece. It becomes a covered state, and the light emitted by the oncoming vehicle can be reliably blocked.

Further, as a third configuration, it has a second light shielding piece opposed to the light shielding piece with a ventilation hole interposed therebetween,
The second light-shielding piece extends from the edge on the other lane side at the edge forming the ventilation hole in an inclined manner to the edge on the one lane side.
According to this configuration, since the louver mechanism is formed by the plurality of light shielding pieces extending opposite to each other from the periphery of the ventilation hole penetrating the front and back surfaces of the antiglare plate, the wind and rain entering the ventilation hole Can be efficiently passed, and the number of parts of the mounting member for fixing the antiglare plate can be reduced.

In addition, as a fourth configuration, a support column that supports the anti-glare plate and a support column holding plate that holds the support column are provided, the support column holding plate extends in the direction of travel of the lane, and extends opposite the fixed plate. And a tightening means.
According to this configuration, since the fixing piece and the fastening means extend opposite to each other, it is possible to securely attach the column holding plate to the attached body such as a guard rail only by performing the fastening work on the fastening means. .
In this specification, “lane” means roads and roads on which bicycles, motorcycles, automobiles and other vehicles can come and go, and “the direction of travel of the lane” is defined by the Road Traffic Act and other regulations. It means the direction in which a defined vehicle should travel.
The above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

To do.
An anti-glare plate 40 that is a main part of the present invention is attached to a portion of the column 30 above the holder portion 14. Hereinafter, the details of the antiglare plate 40 will be described.

As shown in FIGS. 5 and 6, the glare prevention plate 40 is formed so as to surround the flat portion 42 on the inner side of the outer peripheral edge of the flat portion 42 and the flat portion 42 where the plurality of ventilation holes 41 are opened. This is a member integrally formed with a thermoplastic resin in the same manner as the support column holding plate 10.
The flat surface portion 42 is a plate body formed in a substantially rectangular shape, and has a projecting portion 45 that projects in four directions outside the wall portion 43. On the surface of the overhanging portion 45, a reflective tape or the like not shown for securing safety during night driving is attached.
The wall portion 43 is a frame-like piece that protrudes forward and rearward from the front surface and the back surface of the flat portion 42, and is curved and molded so that the upper wall portion 43A has a streamline shape in the width direction.

The column holder part 44 is a hollow part formed in the center part in the width direction of the flat part 42, and continuously extends over the height direction of the flat part 42. The column holder portion 44 has a substantially rectangular cross section surrounded by a front wall 44A corresponding to the surface of the flat surface portion 42, a rear wall 44B corresponding to the back surface of the flat surface portion 42, and a side surface 42C connecting the front wall 44A and the rear wall 44B. It is a region, and is formed so as to be similar to the outer surface shape of the support column 30 so that the support column 30 can be held.
Further, the upper end portion of the support holder 44 is closed by the upper side wall 43A, and the lower end is formed as an opening 44D through which the upper end of the support 30 can be inserted.
Therefore, when the antiglare plate 40 is attached to the support column 30, the upper end portion of the support column 30 held by the holder portion 14 of the support column holding plate 10 may be inserted from above through the opening 44D, which is extremely simplified. It becomes possible to support the anti-glare plate 40. And the glare prevention board 40 attached to the support | pillar 30 is standingly arranged between the lane A and the lane B as a plate body extended in the direction orthogonal to the advancing direction of the lane A and the lane B.

The ventilation holes 41 are a plurality of holes established over substantially the entire area of the plane part 42, and are alternately arranged when the plane part 42 is viewed from the front in terms of ensuring efficient ventilation and strength. Arranged. As shown in FIG. 5 and FIG. 6, the ventilation hole 41 is formed as a long hole elongated in the height direction, from the edge part 42A on the lane A side and the edge part 42B on the lane B side that form the ventilation hole 41. Each of the light shielding pieces 46; 47 rises in the front-rear direction.
Note that the shape of the ventilation hole 41 is not limited to the long hole, and may be various shapes such as a perfect circle and a rectangle.

When the ventilation hole 41 is visually recognized from a vehicle traveling in the lane A, the light shielding piece 46 moves forward from one edge 42A on the lane A side forming the ventilation hole 41 to the other edge 42B on the lane B side. The tip edge 46A is a piece extending while being inclined, and is located on the lane B side from the center L in the width direction when the ventilation hole 41 is viewed from the front.
The front edge 46A is an edge that is curved in an arc shape along the height direction when viewed from the front, and light from a headlight or the like of a vehicle traveling on the lane A indicated by the arrow S1 reaches the lane B side. To prevent.

The light shielding piece 47 is a second light shielding piece corresponding to the light shielding piece 46, and when the ventilation hole 41 is viewed from a vehicle traveling on the lane A, the other edge on the lane B side forming the ventilation hole 41. The tip edge 47A extends from the portion 42B to one edge portion 42A on the lane A side while being inclined rearward, and the tip edge 47A is positioned on the lane A side with respect to the center L in the width direction when the ventilation hole 41 is viewed from the front.
The front edge 47A is an edge that curves in an arc shape in the height direction when viewed from the front like the front edge 46A, and light such as a headlight of a vehicle traveling in the lane B indicated by the arrow S2 is emitted from the front edge 47A. Blocks reaching the lane A side.

That is, the light shielding pieces 46; 47 are arranged in the front-rear direction from the edge portion 42A and the edge portion 42B that form the ventilation holes 41 so as to face each other in parallel or substantially parallel across the ventilation holes 41 on the front surface and the back surface of the flat portion 42. It extends while inclining and is set to a length that exceeds the center in the width direction of the ventilation hole 41 so that the front end edges 46A and 47A overlap each other when viewed from the front, so that the vehicle travels in the opposite lane. The light emitted from the vehicle is surely shielded and a louver for the vent hole 41 is formed.
Therefore, the wind and rain that blows through the ventilation hole 41 indicated by the arrow S3 is guided to the light shielding pieces 46; 47 that are a pair of louvers and smoothly passes through the ventilation hole 41. There is a remarkable effect that local stress concentration does not occur.
And since an excessive moment and stress concentration do not arise in the glare prevention plate 40 itself, it becomes possible to support the glare prevention plate 40 only by the single support | pillar 30, and it is possible to support the glare prevention device 1 with an extremely small number of parts. Can be configured.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the said embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made to the above-described embodiment. It is clear from the description. In particular, in this example, when the ventilation hole 41 is visually recognized from the lane A side for convenience of explanation, the edge portion 42 on the lane A side is described as one edge portion, and the edge portion 42B on the lane B side is described as the other edge portion. However, it is arbitrary which edge is used as one or the other, and the extension direction of the light shielding pieces 46; 47 should be appropriately changed according to the traveling direction of the vehicle traveling in the lane A and the lane B. it is obvious.
