2. Description of the Related Art A louver for a vehicle running road is constructed by arranging a number of wing-shaped louver members in parallel in the vehicle traveling direction. For example, at the entrance and exit of a tunnel, the difference between the brightness outside and inside the tunnel is reduced. It is mainly developed for the purpose of dimming.

In Japanese Examined Patent Publication No. 57-40288, as a louver for an automobile road, a large number of inclined flat plate-shaped louver members are installed in parallel from the south to the north so that light rays are projected on the inclined surface. It is described that these louver members and vertical barrier plates arranged orthogonally to the louver members are formed with light-transmitting pores to improve the light control function.

Further, in Japanese Examined Patent Publication No. 58-10523, a large number of louver members obtained by bending a flat plate into a dogleg shape or a lateral W shape are similarly installed in parallel from the south to the north, and these louver members are installed. A louver member and a vertical barrier plate arranged orthogonal to the louver member in which light transmitting pores are formed are described.

Further, in consideration of the sound absorption, sound insulation effect and ventilation effect by such a vehicle traveling road louver, for example, as described in Japanese Utility Model Publication No. 6-47932, a hollow louver member having a through hole. It has been developed that is filled with sound absorbing material such as glass wool and rock wool.

[0006]

In terms of the light control function of the louver, it is possible to keep the sunlight radiated directly to the vehicle running path as much as possible by the overlapping of the inclined surfaces or the bent surfaces between the louver members. It is necessary to allow the amount of light to be taken in, and particularly in terms of the sound insulation function, it is desirable to make the interval between the louver members as narrow as possible, or use the bending of the louver members to make it difficult for sound to escape.

On the other hand, if the space between the louver members is too small or there is a bent portion, the ventilation is deteriorated and the ventilation function is deteriorated. In addition, dust adheres to the louver member and dust such as leaf fall leaves the louver member. There is a problem that it interferes with the function of the louver because it is stuck in the gap.

The present invention is intended to solve the above-mentioned problems in the prior art, is excellent in the functions of light control, sound absorption, sound insulation and ventilation, and is less likely to be clogged with dust, etc., and easy to maintain. It is intended to provide a louver unit for a vehicle traveling path.

[0009]

According to a first aspect of the present invention, there is provided a louver unit for a vehicle running path in which a plurality of wing-shaped louver members are arranged in parallel inside a frame member at intervals in the vehicle direction. As the louver member, the louver member has a large number of through holes, and the front surface and the rear surface form an arcuate or parabolic smooth curved cross section with a convex shape in the vehicle traveling direction, and the distance between the front surface and the rear surface is high. A louver member comprising a hollow box-shaped body that is large in the central portion in the direction and gradually decreases in the vertical direction, and a sound absorbing material filled inside the hollow box-shaped body. Is.

The most common form of the frame member is a rectangular frame of strip material made of steel or the like, but there is no particular limitation on the outer shape or the like, and the end portion is a tunnel entrance / exit or a structure part of a cut road, etc. Anything that can be installed in If necessary, a girder material or the like can be added in the middle to reinforce.

Since the front and rear surfaces of the louver member have an arcuate or parabolic smooth curved surface shape, turbulence of the air flow during ventilation is small and air permeability is good. Further, in addition to having good air permeability, the smooth curved surface makes it difficult for dust and dirt to collect between the louver members, and accordingly, troublesome maintenance becomes unnecessary.

Further, in the present invention, the louver member is formed such that the distance between the front and rear surfaces is large in the central portion in the height direction and gradually decreases in the vertical direction.
Since the opening distance between the upper and lower parts of the louver unit becomes large, the interior covered with the louver becomes brighter due to natural light, and smoother ventilation performance and rectifying effect can be obtained.

Further, since the air permeability is good and dust and dirt are hard to collect, the interval between the louver members can be set to be small, and there is a high degree of freedom in the design regarding the blocking of direct sunlight and dimming, and the sound absorbing property. It is also advantageous in terms of sound insulation.

The fact that the front and rear surfaces of the louver member have an arcuate or parabolic smooth curved surface is not necessarily limited to the case where the whole is an arc or a parabola, and for example, the lower end or a part of the upper end is a straight line. In case of
Furthermore, the case where the upper and lower ends have horizontal surfaces in the form of upper and lower surfaces is also included. However, the overall shape should be such that the air flow passing between the louver members is not disturbed as much as possible.

The most general form is when the vertical cross sections of the front surface and the rear surface are arcuate surfaces. In this case, the curvature of the front surface of the louver member in the vehicle traveling direction should be larger than that of the rear surface. Thus, the distance between the front surface and the rear surface is large in the central portion in the height direction and gradually decreases in the vertical direction.

As a material for the hollow box-shaped body, a metal such as a steel plate, stainless steel or aluminum is mainly used, but it is also conceivable to use a reinforced plastic or other synthetic resin. In addition, in the case of a hollow metal box, if the surface roughness is increased by dull finish (matte gray matte finish), light reflection can be controlled in the form of diffusing light and glare can be suppressed. . Further, a photocatalyst can be applied to the surface of these to prevent surface contamination and purify exhaust gas.

The method of forming the through holes of the hollow box-shaped body is not particularly limited, but it is economical to form the hollow box-shaped body with a punching plate or expanded metal. As the sound absorbing material, glass wool, rock wool or the like used in the conventional louver member or the like can be used, but it is not particularly limited as long as it is a sound absorbing material that can be filled and held in a hollow box-shaped body having a through hole.

A second aspect of the present invention is the louver unit for a vehicle running path according to the first aspect, wherein the hollow box-shaped louver unit has a front surface and a rear surface with a stainless open area ratio of 50.
This is the case where a punching plate (having a large number of through holes) of ˜70% is used.

From the viewpoint of durability, stainless steel or the like is suitable as each component of the louver unit,
Claim 2 limits that case. Moreover, the reason why the porosity is 50 to 70% is to enhance the sound absorbing effect as much as possible. However, when the porosity is 70% or more, the surface of holding the sound absorbing material and a part of inflow of rainwater, dust and the like enter. Maintenance may be troublesome. In addition, if the outer peripheral portion of the punching hole as the through hole projects to the outer surface of the hollow box-shaped body, the effect of suppressing the inflow of rainwater is enhanced.

According to a third aspect of the present invention, in the louver unit for a vehicle traveling road according to the first or second aspect, with respect to the louver members arranged in parallel, a part of the central portion of the louver member at the rear of the vehicle traveling direction is the vehicle traveling direction. This arrangement limits the case where direct sunlight does not enter the vehicle running path by arranging the louver member on the front side in the vertical direction that connects the upper and lower rear ends of the louver member to the front side.

As described above, the louver unit for vehicle traveling road according to the present invention is excellent in ventilation performance and rectification effect, and therefore the interval between the louver members can be set small enough to block direct sunlight. it can.

FIG. 1 shows an embodiment of a louver unit for a vehicle running road according to the present invention. The louver unit 1 includes a frame member 2 in which vertical girders 2a and horizontal girders 2b are assembled in a rectangular shape. A large number of wing-shaped louver members 3 each having an arc-shaped cross section inside are arranged in parallel in the vehicle traveling direction to form a panel shape.

The panel-shaped louver unit 1 has, for example, the digging road 11 shown in FIG.
It is installed on the opening and constitutes a louver for dimming, sound absorption, sound insulation and ventilation.

In this example, each louver member 3 is formed into a smooth curved surface whose front surface has a curvature larger than that of the rear surface and which is convex in the vehicle traveling direction in its cross section, and forms a crescent-shaped hollow box as a whole. As shown in FIG. 2, a sound absorbing material 4 such as glass wool is filled in the inside thereof.

As described above, the louver member 3 has a large width at the center in the height direction and a narrow width at both upper and lower ends. This is intended to smooth the inflow of air from between and to make the light control surface brighter when the intervals between the louver members 3 are the same.

Further, in this example, as shown in FIG. 2, a part of the central portion of the louver members 3 behind the louver members 3 adjacent to each other in the vehicle traveling direction, that is, a portion projecting forward is forward in the vehicle traveling direction. By arranging the louver member 3 to enter the inside (front) on a vertical line connecting the upper and lower ends of the louver member 3, the direct sunlight is prevented from entering the vehicle traveling path.

Further, in this example, the hollow box-shaped body of the louver member 3 filled with the sound absorbing material 4 is made of a stainless steel punching plate having a large number of through holes 5 to allow the noise when the vehicle is passing through the holes. The sound absorbing material 4 is absorbed through the sound absorbing member 5.

As described above, the aperture ratio is preferably 50 to 70% on the front surface and the rear surface of the louver member 3, but the horizontal planes at the upper and lower ends are not provided with through holes. As for the upper surface, it is mainly to prevent rainwater and the like from directly invading the upper surface and to prevent dirt and dust from entering the interior filled with the sound absorbing material, while the lower surface is mainly The sound insulation effect is taken into consideration.

As shown in FIG. 4, the louver member 3 is arranged so as to be convex in the vehicle traveling direction, so that when it is applied to a tunnel entrance / exit portion or a ceiling of an excavated road, the louver member 3 can be moved to a ceiling by a traveling vehicle passing therebelow. An air flow in the vehicle traveling direction is generated on the lower surface of the part, and the louver member 3 captures the air flow and discharges it together with the exhaust gas to take in fresh air from the outside in a form of natural circulation to enhance the ventilation effect. be able to.

[0031]

According to the louver unit for a vehicle running road of the present invention, the front and rear surfaces of the louver member are formed into a smooth curved surface shape, and the upper and lower opening intervals between the louver members are large, so that ventilation is good in ventilation. Since the front and rear surfaces of the louver member have a smooth curved surface shape, in addition to good air permeability, it is difficult for dust and dirt to collect between the louver members, and maintenance for clogging between louver members, which has been a big problem in the past, can be performed. It's easy. Since the louver members have good ventilation and dust and dirt are hard to collect, the distance between the louver members can be made small, and in combination with the curved shape of the louver members, it blocks direct sunlight and has a high degree of freedom for dimming. . Similarly, since the interval between the louver members can be reduced, it is advantageous in terms of sound absorption and sound insulation, and the degree of freedom in design is high. Since the distance between the upper and lower openings is larger than that in the center of the louver member in the height direction, even if the distance between the louver members is kept small, the light control function becomes brighter. In the invention according to claim 3, the direct sunlight is completely shielded, so that the safety of the driver can be protected.
