[Invention Title]
A ROTATING TYPE GLARE SCREEN [Technical Field] The present invention relates to a glare screen installed on the top of a median strip on a road to ensure safe driving by blocking light of headlamps of vehicles running on opposite roads, and more particularly to a rotating type glare screen whose glare screen wings are vertically installed between upper and lower horizontal frames at regular intervals to be capable of rotating by wind, thereby preventing breakage of the glare screen and any accidents caused therefrom, preventing any traffic accidents due to careless driving by allowing a driver to recognize the median strip easily, and enabling to give a good view to drivers. [Background Art]
Glare screen is a safety installation for safe driving by blocking light of vehicles running oppositely at night and preventing drivers from being dazzled. The glare screen is configured so that wire netting is installed on the top of a median strip with a slope, or fixed glare screen wings are installed between upper and lower frames at regular intervals. In addition, a median strip may be extended upward to give an additional function as a glare screen. As mentioned above, the conventional glare screen blocks light of headlamps by wire netting, glare screen wings or median strip, thereby ensuring safe driving, particularly at night.
However, the conventional glare screen is fixed, so it may not endure strong wind pressure. Thus, the conventional glare screen is apt to be fallen down from the median strip by strong wind, resulting in failing to give its function. Sometimes, the conventional glare screen flies to the road to cause car accidents. [Disclosure] [Technical Problem]
The invention is designed to solve the problems of the prior art, and therefore it is an object of the present invention to provide a glare screen that may endure strong wind pressure and call attention of drivers to help safe driving. In
order to accomplish the above object, the present invention provides a rotating type glare screen that includes glare screen wings vertically installed at regular intervals to be rotatable so that the glare screen wings may rotate in a direction decreasing the effect of wind pressure and thus be protected when strong wind pressure is applied thereto, and so that the glare screen wings may easily rotate in line with air flow caused by running vehicles, thereby calling attention of drivers and allowing drivers to accurately predict road states such as irregularity or curve. [Technical Solution]
A glare screen 100 of the present invention includes upper and lower horizontal frames 1 , right and left vertical frames 2 supporting the horizontal frames 1 , and a plurality of glare screen wings 3 vertically fixed between the horizontal frames 1 at regular intervals, wherein the glare screen wings 3 are rotatably installed to the horizontal frames 1.
That is to say, the glare screen wing 3 of the present invention has a plate shape long in a vertical direction, a rotary shaft 4 is protruded on centers of upper and lower ends thereof, and the rotary shaft 4 is axially supported by the upper and lower frames 1 to be capable of rotating.
And the rotary shaft 4 of the glare screen wing 3 is axially installed in holes
5 formed in the horizontal frames 1 to be rotatable, or the rotary shaft 4 is inserted into bushing caps 6, made of cupper alloy to act as bearings, mounted in the holes
5 of the horizontal frames 1 to rotate smoothly. A horizontal section of the glare screen wing 3 has two curved arc shapes composed of convex arc 7 and concave arc 8 symmetrically based on the rotary shaft 4. More specifically, the glare screen wing 3 is installed so that the concave arc 8 is oriented to a running direction of vehicle.
In addition, the horizontal frames 1 and the glare screen wings 3 are made of PVC, or synthetic resin or wasted plastic may be recycled to make them.
As shown in Fig. 4, in the present invention, the rotary shaft 4 is protruded on the upper and lower centers of the glare screen wing 3, so it is inserted into the holes 5 of the horizontal frames 1 respectively. In addition, it is also possible that the bushing caps 6 are installed in the holes 5, and then the rotary shaft 4 is
inserted into the bushing caps 6. In this case, the bushing cap 6 acts as a bearing, ensuring smooth rotation. Here, the bushing cap 6 may be synthetic resin, copper alloy or other various materials containing lubricant.
The glare screen of the present invention, configured as mentioned above, is installed to a support 10 stood on the upper surface of a median strip 9 or on a road surface, as shown in Figs. 1 and 6.
The glare screen 100 installed on various roads such as highway are exposed to natural circumstances, so it is seriously affected by wind and rain. A conventional glare screen was apt to be broken down or fallen on the road, not enduring strong wind pressure exerted thereto, which may cause serious accidents. It is because the conventional glare screen does not have a structure capable of escaping wind pressure, and the conventional glare screen is fixed to receive the wind pressure as it is.
However, the glare screen wing 3 is rotated to protect the glare screen 100 when strong wind pressure is applied thereto.
That is to say, when receiving wind pressure, the glare screen wing 3 rotates on the rotary shaft 4, so an area exposed to the wind pressure is decreased. Thus, the glare screen wing 3 of the present invention reduces the area exposed to wind pressure by rotating though strong wind pressure is applied thereto, thereby protecting the glare screen wing 3 and the glare screen 100, and preventing any accidents in advance.
In addition, as shown in Fig. 4 & 5, the glare screen wing 3 has two curved arc shapes composed of convex arc 7 and concave arc 8 symmetrically based on the rotary shaft 4, and the glare screen wing 3 is installed so that the concave arc 8 is oriented to a running direction of vehicle.
Thus, the glare screen wing 3 may rotate due to wind caused by pressure difference generated by advancing vehicles. That is to say, in the case that a vehicle runs in a right portion of the road, since the glare screen wing 3 is configured as mentioned above, the glare screen wing 3 is rotated in a counterclockwise direction if a vehicle runs in a direction designated by a big arrow in Fig. 5. It is possible because the glare screen wing 3 is configured so that the concave arc 8 is toward an advancing direction of vehicle and the convex arc 7 is
toward the rear of vehicle. That is to say, the concave arc 8 is positioned in front of vehicle so as to receive more wind pressure caused by an advancing vehicle, thereby rotating in a counterclockwise direction.
Since the glare screen wing is configured to rotate by external wind as well as advancing vehicle, it may call attention of drivers and allows drivers to recognize position and shape of the center line such as irregularity and curve, thereby assisting in safe driving.
In order to ensure free and smooth rotation of the glare screen wing 3, bearings may be mounted in the upper and lower horizontal frames 1 and then the rotary shaft 4 of the glare screen wing 3 may be axially installed to the bearings.
In other case, the rotary shaft 4 may be axially mounted to the bushing caps 6 acting as bearings, as shown in Figs. 3 and 4.
The bushing cap 6 is made of materials helpful for rotation of the rotary shaft 4, and preferably made of copper alloy or synthetic resin containing lubricant. Thus, the glare screen of the present invention may endure strong wind pressure without hiding scenery view, allow drivers to easily recognize the road shape by means of rotating structure, and help drivers to drive safely by calling their attention.
[Advantageous effects] As described above, the glare screen of the present invention includes the rotating glare screen wings 3, so the glare screen wings 3 and the glare screen 100 are protected against strong wind pressure, and the rotating glare screen wings 3 may call attention of drivers to assist in safe driving. In addition, since visual recognition of drivers is improved, the drivers may check irregularity or curve of the road and prevent any accidents in advance. [Brief Description of Drawings]
