[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stand-alone separate light-shielding net for roads which is scattered at predetermined intervals on a median strip or the like of a road.

[0002]

[Prior art]

 Generally, as a light-blocking means to prevent dazzling of headlights from oncoming vehicles in the median divider on the road, etc., a planting structure by planting evergreen trees with a predetermined height in the divider or in the longitudinal direction of the road There are known a net structure in which a band-shaped light-shielding net having a constant width is stretched, and a wall structure in which a simple board is continuously provided in the longitudinal direction. As described above, the light shielding means for preventing glare of the headlights is extremely unattractive because the exhaust gas adheres rapidly and becomes dirty immediately because of the use of the road where the installation place receives the exhaust gas of the vehicle.

[0003]

[Problems to be solved by the invention]

 That is, in the above-mentioned light-shielding means for preventing dazzle, for example, in a planting structure, tree branches and leaves must be trimmed or felled periodically, which is troublesome, and is particularly troublesome on a highway. In addition, work hours are limited, making maintenance and management difficult and costly. In addition, mere net structures and wall structures are extremely blackened by exhaust gas and the like, and are quickly blackened, the appearance of dirt is poor, and the cleaning work is difficult. At present, periodic cleaning work is not performed. In particular, long-distance net structures will inevitably become loose during long-term use, resulting in reduced light-blocking effects and unsightly appearance.

In view of the above circumstances, the present invention provides a separate (independent) light-shielding net in which a rectangular net as a unit structure is fitted into a predetermined support frame, and this is fixed at a guard rail position of a median strip. An object of the present invention is to provide a separate light-shielding net for roads that solves the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 According to the present invention, a detachable stopper is provided at a peripheral edge of a rectangular net having a fine mesh formed of a synthetic resin fiber of green or the like to form a light shielding net main body, and the light shielding net main body is protruded at a lower end with a support leg. The light-shielding net unit is formed by detachably stretching the fasteners in the frame of the rectangular support frame that has been installed to form a light-shielding net unit. The main body of the light shielding net is attached to the pillar part directly protruding from the pillar part or the median strip, etc., so as to be arranged transversely to the longitudinal direction of the road.

In this case, the rectangular supporting frame is a rectangular supporting frame in which a receiving piece corresponding to the attaching / detaching stopper is protruded in the frame.

Further, the light shielding net body has a net surface provided with information means such as characters and symbols.

As described above, the road-type separate light-shielding net faces the light-shielding net main body of the rectangular net that fits into the predetermined rectangular support frame, and is stretched with appropriate fasteners to form a light-shielding net unit configuration. For this reason, independent and scattered arrangements are made at predetermined positions on the guard rails, such as the median strip, which are dazzled by the light of automobiles. Prevent dazzling.

In addition, since the shading net body is configured to be detachable from the support frame, if the net body becomes dirty due to long-term use or the like, only the shading net body in the soiled portion is loosened by loosening the fastener and the supporting frame. It can be removed from the body and replaced with a new shading net. In other words, partial replacement is possible, and a single net is divided into small areas, so that it will not loosen even when used for a long time, and it will have a good appearance and will be easy to maintain and manage.

Further, since the light shielding net body is a detachable type, if information means representing appropriate characters and symbols is attached to the net surface of the light shielding net body by sticking or painting, predetermined items for the occupant of the automobile can be satisfied. Notifications (for example, safety guidance and other general publicity) can be easily performed. Of course, it is sufficient to return to the normal (plain) light-shielding net main body after the predetermined period has passed. That is, it is suitable for obtaining a short-term PR effect.

[Embodiment of the invention]

 Hereinafter, an embodiment of the separate light-shielding net for roads according to the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a separate type light-shielding net to be attached to a guardrail position of a median strip. Reference numeral 1 denotes a mesh (for example, 1 mm square) formed of synthetic resin fibers having green-friendly colors such as green and gray. A light-shielding net body made of a square net body a having a fine mesh (a fine mesh), and a so-called waist-like peripheral edge of the light-shielding net body 1 that is folded back by a predetermined width to form a plurality of eyelet structures. An attachment / detachment stopper 2 is provided. Reference numeral 3 denotes a rectangular support frame, which is formed of a metal member such as an aluminum material or an iron material, a synthetic resin material, wood, or the like, and has a size such that the rectangular light shielding net main body 1 fits therein. Is formed by projecting a prismatic support leg 4 of a predetermined length at the lower surface position of the lower frame portion 3a and projecting a plurality of receiving piece portions 6 each having a mounting hole 5 inside the rectangular support frame 3. Become. The light-shielding net main body 1 is fitted into the frame of the support frame 3, and the through-hole 2 a of the attachment / detachment stopper 2 on the periphery of the light-shielding net main body 1 matches the mounting hole 5 of the receiving piece 6 on the support frame 3 side. Then, a tightening member 7 made of a bolt or the like is inserted into the mounting hole 5 and the through hole 2a, and is fixed to a back portion thereof by tightening a tightening piece 7a made of a nut or the like. Thus, the light shielding net unit 8 is constituted as a whole. Reference numeral 9 denotes a guardrail laid on the median strip B of the road A. The support legs 4 of the light-shielding net unit 8 are fixed to pipe-shaped support portions 10 arranged at regular intervals to support the guardrail 9. In this case, the support fitting 12 is brought into contact with a part of the support 10, the fastening U bolt 11 for winding the support fitting 12 around the support 10 is inserted, and nuts 11 a are attached to both ends of the fastening U bolt 11. The support legs 4 of the light-shielding net unit 8 are inserted into the frame-shaped receiving groove holes 12a protruding from the fixed support fittings 12 and fixed upright to be mounted as a light-shielding net 8 '. In this case, the shapes of the rectangular light-shielding net main body 1 and the rectangular supporting frame 3 are vertically elongated rectangular shapes or square shapes as shown in the figure depending on the site.

Next, this operation will be described. The mounting work for arranging the light-shielding net units 8 at a fixed interval at the position of the guard rail 9 of the median strip B includes a predetermined support portion installed at a fixed interval on the guard rail 9 side. First, the support fitting 12 is attached to the reference numeral 10. In this case, the setting direction of the net surface 8a of the light-shielding net unit 8 may be a horizontal arrangement orthogonal to the longitudinal direction of the road A as shown in FIG. As shown in FIG. 6 (B), a horizontal arrangement having an angle (α) slightly inclined at 10 ° to 15 ° with respect to the longitudinal direction of the road A is adopted. At this time, in the case where the support bracket 12 is arranged orthogonally to the road A, the fixing position of the support bracket 12 arranged on the support column 10 is set in parallel with the support bracket 9a that directly supports the guardrail 9, so that the support bracket 12 can be inserted into the receiving groove hole 12a. By simply dropping the prism-shaped support legs 4 on the light-shielding net unit 8 side, they can be easily arranged orthogonally. In addition, in an arrangement in which the road A is appropriately angled, the fixing position of the support fitting 12 with respect to the column 10 may be set in advance.

The frame-shaped receiving groove 12 a of the support fitting 12 and the support leg 4 of the light shielding net unit 8 are each formed in a rectangular shape capable of fitting in a sectional shape, and the support fitting 12 is provided at two positions above and below the support column 10. In this case, the mounting operation is completed only by dropping the support legs 4 of the light shielding net unit 8 into the frame-shaped receiving slots 12a of the support fittings 12.

Here, a headlight of an automobile (not shown) running on the road A irradiates forward with a certain illuminating angle, but the light shielding net 8 ′ is fixed at a center separation zone B on the center line side. Since the lights are scattered on the median strip B side, the lights scattered on the side of the median strip 8 'hit the net surface 8a of the shading net 8' and are shielded by the fine mesh, so that light does not leak to the opposite road. That is, a light blocking effect is achieved.

Further, like the light shielding net 8 ′ of the other embodiment shown in FIGS. 9 and 10, the information means 13 for indicating appropriate characters and symbols is attached to the net surface 8 a of the light shielding net main body 1. Is also good. The information means 13 can display, for example, characters (safety, traffic, etc.) as shown in the drawing by applying a fluorescent paint or attaching a reflective sheet, so that the driver or passengers can visually recognize the information while driving. Dive various PR effects naturally.

Of course, the light-shielding net main body 1 itself with respect to the light-shielding net unit 8 is configured to be detachably attached to the support frame 3 with a simple fastener 7 such as a bolt. If the tightening piece 7a of the tightening member 7 is loosened and removed, for example, when it becomes dirty with exhaust gas or the like, a new or washed light-shielding net main body 1 can be easily replaced on the spot.

In addition, even with the use of the light-shielding net 8 ′ in which the information means 13 is arranged on the net surface 8 a, if the PR period (for example, the period of the traffic safety week slogan or the event sign of each place) is over, the original is used. What is necessary is just to switch to the ordinary light-shielding net main body 1 which becomes the solid net surface 8a.

[Effect of the invention]

 As described above, the separate light-shielding net for roads of the present invention has a rectangular shading net main body made of synthetic resin fiber having a predetermined fine mesh, and a support leg protruding from the lower end to be attached to the support side of the guard rail of the median strip. It is a detachable extension that fits into the rectangular support frame, and a separate type light-shielding net configuration in which the support legs are fixed to support columns at least at predetermined intervals of the guard rail of the median strip with support brackets, which is extremely simple. It has a simplified light shielding net structure, and is easy to manufacture, easy to perform on-site, and has good workability. In addition, since the light-shielding net body has a detachable structure, only the light-shielding net body (single unit) that has become defective is replaced with a support frame when it is contaminated with exhaust gas or when it is partially damaged. Repair can be performed in a short time, and a light-shielding net with excellent workability, such as a highway, that takes safety into consideration can be obtained.

Further, information means such as appropriate characters and symbols is applied to the one or a plurality of light-shielding net bodies independently arranged in a standing manner in the direction of the road, and a predetermined number is applied to the entire light-shielding net body marked with this sign. PR is performed, and after the PR period, it is possible to return to the original light-shielding net main body. The size of the light-shielding net body may be appropriately set in consideration of the road conditions, the background of the site, and the like.
