Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windbreak fence installed on a highway or the like, and more particularly, the fence automatically rises according to the intensity of the blowing wind, and the fence is automatically activated when the wind intensity falls below a certain value. The present invention relates to a wind-operated windbreak fence that has fallen down so that the scenery of the coast and the like can be enjoyed from inside the vehicle.

[0002]

2. Description of the Related Art The road environment in Japan has undergone remarkable development, and highways have been developed in mountainous areas and along the coast. 2. Description of the Related Art Conventionally, on a highway, a windbreak fence is provided to cover the outside of the road to prevent a strong wind, and the strong wind blown is prevented by a fence having a strong structure, thereby reducing the influence on a running vehicle body. In particular, in snowy and cold regions, accidents often occur due to poor visibility such as snowstorms and storms in winter, and traffic safety measures are required. It is not an exaggeration to say that what is needed in this case is countermeasures against crosswinds, and in particular, fences to prevent storms from the coast are important. However, the appearance of the windbreak fence that covers the outside of the road is often murky, and the appearance is impaired. The present applicant has prepared a perforated plate having the elasticity, a semi-circular shape at the center of the panel, and a large number of fine holes by press-forming using a steel plate having a thickness of 1.6 mm. It has been proposed and put into practical use. If a windbreak fence is installed along the road using this perforated plate, the roadside scenery is quite good because of good visibility, but it is naturally possible to enjoy a satisfactory aesthetic without the windbreak fence.

[0003]

Therefore, in order to enjoy the scenery, a foldable windbreak fence has already been put into practical use. However, as a method of opening and closing the windbreak fence, human labor and electric power are required. Because of the use of energy, it was costly and time-consuming. In other words, when there is no wind, keep the windbreak fence down, enjoy the scenery from the inside of the car, and when the strong wind blows, the staff will use human power,
Alternatively, a device in which a switch is turned on to electrically stand a windbreak fence has been proposed and put into practical use. However, an increase in human labor, an increase in electric power, and an increase in cost have occurred.

Accordingly, an object of the present invention is to solve these conventional problems, and to automatically open and close a windbreak fence according to the strength of the blowing wind, so that the view can be enjoyed when the wind is weak, and the strong wind can be prevented. At times, it is intended to provide a wind-operated windbreak fence that raises the windbreak fence with the wind to protect the vehicle body from crosswinds and eliminates the cost and human power.

[0005]

In order to achieve the above-mentioned object, in the wind movable type windbreak fence of the present invention, a shaft supporting the windbreak fence is provided with a horizontal axis, and the windbreak fence is centered on the axis by wind force. So that it can rotate back and forth. The surface of the windbreak fence is formed by a perforated plate, and a pressure receiving plate that receives wind pressure at right angles to the windbreak fence is provided. If a strong wind blows from the front of the windbreak fence while the windbreak fence is lying down horizontally,
When the pressure receiving plate falls due to the strong wind, the windbreak fence integrated with the pressure receiving plate is lifted to the front. The lifted windbreak fence is fixed by a latch for a predetermined time, and after the elapse of the time, the solenoid operates to release the latch. When the strong wind stops, the upper stage of the windbreak fence falls down to the rear of the windbreak fence, but by installing a rotary damper between the windbreak fence and the supporting column, the upper stage of the windbreak fence does not fall down strongly behind the windbreak fence. Constitute. With such a configuration, it is possible to protect the vehicle body traveling on the road from a side wind when the wind is strong, while the landscape can be viewed when there is no wind, so that a windbreak fence convenient for the driver is provided. Further, since wind power is used, there is an advantage that cost and manpower are not required as compared with a folding wind fence of a manual type or an electric type.

The right part in FIG. 4 is a movable part that is fitted to the fixed part and that rotates about the shaft 12 according to the presence or absence of wind. FIG. 3 shows an assembled part in which the fixed part and the movable part are fitted to each other, and is a main structure of an actual wind movable type windbreak fence in a horizontal state. Since the perforated plate 10 of the windbreak fence is in a horizontal state, the pressure receiving plate 11 is attached to the angle 11a which is attached at a right angle thereto, and the pressure receiving plate 11 stands in a vertical state. On the extension of the horizontal perforated plate 10, a striker 17 is attached via a pillar. When a strong wind blows from the no-wind state, the pressure receiving plate 11 receives the wind,
After slightly lifting the perforated plate 10 of the windbreak fence, the windbreak fence receives the wind further and stands upright on the top of the windbreak fence. When the windbreak fence rises, the striker 17 stops at the cushion rubber 16a as shown in FIG. At the same time as stopping, the striker 17 is locked by the latch, and the fixed portion and the movable portion are fixed. At the same time, the reed switch provided on the column 19 comes into contact with the magnet provided on the windbreak fence, and the operation switch to the circuit is turned on. The weight plate 17a shown in FIG. 1 is attached below the perforated plate 10, and is for adjusting the weight so that an arbitrary wind value can be set.

a is attached. In this state, a strong wind blows on the perforated plate 10 to keep the windbreak fence in a standing state. When there is no wind, the windbreak fence is kept up for a predetermined time (for example, one hour). After that time, the latch is released and the rotary damper 13 is released.
The perforated plate 10 falls down slowly due to the function of a. The rotary damper 13a is provided inside the position of the center of gravity 12 of the perforated plate 10 shown in FIGS. The perforated plate 10 is shown in FIG.
As shown in (d), the panel has a plurality of semicircular portions at the center, and the wind passing through the small holes is dispersed in the vertical direction due to its cross-sectional shape, thereby exhibiting windproof and snowproof effects. .

FIG. 5D shows a positional relationship when the perforated plate 10 is in a horizontal state, and the pressure receiving plate 11 is attached in a direction perpendicular to the perforated plate 10 from the center axis 12. When there is no wind, the state shown by the solid line in FIG.
When a strong wind (here, designed at 7.5 m / sec) blows, the pressure receiving plate 11 receives the wind pressure, and the wind pressure causes the state shown by the broken line in FIG. 5D. The right side is the upper side and the left side is the lower side from the center 12 where the rotary damper 13a is provided.
The upper part of the windbreak fence is set up vertically by the wind force and the weight of the weight plate 17a, and the state shown in FIG. As shown in FIG. 5B, instead of the semicircular shape of the perforated plate 10, a recess having a shape using Bernoulli's theorem can be provided. That is, when the wind blows in parallel with the perforated plate 10 in a horizontal state, the pressure on the upper side of the perforated plate 10 is small and the pressure on the lower side is large.
The function of lifting is generated. By utilizing this function, a force for raising the perforated plate 10 can be generated. FIG.
(C) shows an alternative to the weight plate 17a,
In FIGS. 5A and 5D, a U-shaped steel plate is used.

The perforated plate 10 is separated from each other by pillars 19 at both ends, and each pillar 19 is buried and fixed in the ground 18 below. As described above, since the perforated plate 10 is separated and independent for each of the columns 19 at both ends, it is possible that only a part of the perforated plate 10 is in a vertical state and the other part is in a horizontal state in a long range. It is. Although the perforated plate 10 is used as a panel of the windbreak fence, expanded metal, perforated metal, wire mesh, glass, a blind plate, or the like can be used as an alternative material. Also,
The windbreak fence of the present invention is mainly provided for the storm from the shore, and the windbreak fence of the present invention is installed between the road and the shore, and the perforated plate 10 is provided when the storm blows from the sea. The perforated plate 10 is prevented from rising even when the wind is blown up. If the land side is a place such as a cliff, the landscape is not so relevant, and the windbreak fences arranged on the land side of the road may be always standing. It is a matter of course that both the windbreak fences arranged on both sides of the road can be the wind-operated windbreak fences of the present invention, and any design can be adapted to the terrain.
Further, the shape of the road does not always run parallel to the coast, but may be a shape that is bent at a right angle from an oblique direction or a parallel state. Therefore, within the long range, some perforated plates 1
There is no problem if only 0 rises and the other parts remain horizontal. Also, an arbitrary wind force can be set by adjusting the weight of the weight plate 17a. Thus, it is possible to make it easy to start up in a certain place and to make it difficult to start up in a certain place.
