イトによる眩惑防止手段とする。<Prior art> Generally, on expressways and other ordinary roads where the road curves, a large number of line-of-sight guide marks are scattered along the road edge, and these line-of-sight guide marks are arranged in a row. The driver checks the road condition by receiving the reflected light. Currently, this type of line-of-sight guide E is attached to a separate support provided on the top or back of a guardrail installed at the roadside (see Fig. 7). Moreover, in this case, the configuration of the line guide is complex, with a mirror structure that combines a support frame and a reflector body with reflective grooves engraved on the entire interior surface.
It's getting expensive. Furthermore, each reflector must be installed at a predetermined location (according to traffic safety facility design guidelines, the height of the reflector is 120 cm above the road shoulder pavement), which is cumbersome. Of course, if this line-of-sight guide mark is attached to the median strip, a light-shielding net is further stretched over the back of the line-of-sight guide mark to prevent dazzling caused by the headlights of oncoming vehicles.
〈考案が解決しようとする問題点〉

The current situation is that this leads to high costs.

When the main body of the light-shielding net is stretched over the median strip, it is placed at a predetermined position, such as at the eye level of a passenger car driver, using a reflective sheet or a synthetic resin flat reflector plate with reflective grooves arranged inside. This is a light-shielding net having a line-of-sight guiding function by sequentially attaching flat reflectors at regular intervals in the longitudinal direction.

At the same time as this, a visual guide beacon was installed. In other words, if the flat reflector is pre-installed on one side (face) of the light-shielding net and is placed at a height that meets the design guidelines of a traffic control facility, the flat reflector will immediately function as a visual guide. do. Of course, there is no need to provide special supports (pillars), unlike in the case of installing line-of-sight guideposts, and the construction period can be simplified.
〈実施例〉
以下、本考案を実施例の図面に基づいて詳述す

ト裏面に貼着用接着剤4を配している。 1 is, for example, a strand of polyester filament 1200 denier spun-dyed yarn (green), which is knitted at a predetermined interval in the warp section a, and the weft section b of the same material is perpendicular to the warp section a by an appropriate number of widths. The main body of the light-shielding net is braided, and the shielding portions 2a and the ventilation stitches 2b are arranged in a staggered manner as a whole. When stretched over the upper part of the guardrail B of part A, an orange reflective sheet 3 serving as a flat reflector is placed at the lower position 1b, which is at the eye height h of a passenger car driver (for example, 120 cm above the ground). The light-shielding net 5 is attached at regular intervals in the direction and has a line-of-sight guiding function. In this case, the structure of the reflective sheet 3 is such that, for example, minute glass beads 3c are embedded between a transparent film 3a and a reflective film 3b to form a retroreflective structure, and a pasting adhesive 4 is disposed on the back surface of the sheet.

高さ位置に設定されるものとなる。 To explain this effect now, first, the work of stretching the shading net 5, which also serves as line-of-sight guide, at the upper position of the guardrail B of the median strip A on the road is a simple work of stretching a shading net. Similarly, the light-shielding net 5 is stretched and hung on a net support D erected on the support C of the guardrail B by placing a special tensioning jig (not shown) at one end. In this case, three reflective sheets previously attached to one side of the light shielding net 5 are stretched so as to face the main road side. The reflective sheet 3 provided at the bottom of the light-shielding net 5 thus stretched is automatically set at a height position that is in the line of sight of the driver.

でもくつきりと輝き、確実な道路線形を知る。 Here, since the reflected light from the three groups of reflective sheets provided at the bottom of the light-shielding net 5 inevitably enters the field of view of the driver of a passenger car traveling on the road, the longitudinal arrangement of the three groups of reflective sheets This allows you to understand the road alignment. Of course, this reflective sheet 3 is coated with fluorescent paint, so it shines brightly not only during the day but also at night, allowing you to know the exact road alignment.

分散され、運転者に対し眩惑を与えない。 In addition, even when the headlights of an oncoming vehicle are illuminated at night, the shape of the shielding net main body 1 is such that the shielding portion 2a is formed from the weft portions b of a plurality of strands.
(for example, 8 mm width) and the ventilation meshes 2b are arranged in a staggered manner in the upper and lower rows and in the left and right directions, so that light rays diagonally ahead are blocked, or even if there is transmitted light, it is dispersed by the fabric, causing dazzling to the driver. I won't give it.

に押圧嵌合し、所謂雄雌ホツク止めとする。 FIGS. 5A and 5B and FIG. 6 show other embodiments of the flat reflector, which are configured as flat reflectors made of synthetic resin. That is, the flat reflector 3' has a flat triangular cross section with a slightly thicker wall c at the front in the direction of travel and a thinner wall d at the front in the direction of travel, and exhibits a reflected wavefront 7 as a whole inside the surface, and has reflective grooves 8. This is a structure in which the formed reflective layer portion 8' is disposed. However, the surface is a flat surface 9 that does not attract dust or the like. In this case, when attaching the flat reflector 3' to the light-shielding net main body 1, a pair of other flat reflectors 3' are used together on the back side of the light-shielding net main body 1. For example, as shown in FIG.
A locking head 10a protrudes from the back surface of one of the flat reflecting plates 3', facing each other with the thick wall c side facing forward in the direction of travel.
The retaining leg 10 is inserted through the ventilation mesh 2b, and a receiving hole 11 is bored in the thin wall d portion of the other flat reflector 3' on the back side.
This is a so-called male and female hook connection.

肉の傾斜としてなるため、進行方向の視線におい

し多量の反射光を受ける(第6図矢印参照)。 The reflection from the light shielding net 5 is caused by the fact that the flat reflector 3' has a reflective layer 8' having a reflective wavefront 7 and fine reflective grooves 8 within its surface as a whole, and has a thick slope in the traveling direction. The reflection area in the line of sight is substantially expanded, the reflection angle also increases, and a large amount of reflected light is received (see arrows in FIG. 6).
尚、中央分離帯部Aの防護柵がガードケーブル

体の取付位置は、あくまで運転者の目の高さ位置
とする。 In addition, when the protective fence of the median strip A is a guard cable, the shape of the light-shielding net 5 should be a wide net that reaches the lowest cable position, but the installation position of the flat reflector should be determined according to the driver's eyes. height position.

の実用的効果を奏する。<Effects of the invention> As mentioned above, the light-shielding net having the line-of-sight guide function of the present invention has a structure in which flat reflectors are integrally arranged at an appropriate height position on at least one side of the light-shielding net body woven from synthetic resin fibers. As a result, the line guide sign and the light shielding net can be installed in one step, and not only is the workability extremely high, but the structure is simple and can be provided at low cost. Furthermore, since the flat reflector integrated into the net main body is formed from a reflective sheet or a flat synthetic resin plate, it is lightweight and does not interfere with the tensioning of the net (does not cause loosening). In addition, the flat reflector is a flexible type that can be attached with adhesive or snaps using a mesh, so it is practical, such as allowing you to freely set the installation position and installation interval of the flat reflector depending on the curve of the road, etc. It has the desired effect.
