Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a ventilation system installed on the roof of a relatively small-scale leisure facility such as a barbecue house.

[Conventional technology]

The applicant has already developed and filed an application for a ventilation system installed in the roof ridge for natural ventilation, which is high-performance and has good rain protection (Japanese Patent Publication No. 62-62221,
62-63749). To briefly explain its features with reference to Figure 6, the louver wings, which previously were facing downwards, were now facing upwards as shown in Figure 6, A and B, and were placed on both sides of the ventilation system. They are installed vertically or at an angle, and by doing so, ventilation is promoted by the force of the wind, resulting in extremely good natural ventilation performance, and it also prevents wind, rain, and snow from entering the inside of the louver. Even if the rainwater is spilled, it does not reach the inside of the room and instead flows downwards, resulting in a revolutionary improvement in rain protection. However, in these ventilation systems, each ventilation member is shaped like a panel, so effective ventilation cannot be achieved unless the wind direction is approximately perpendicular to the panel surface. The disadvantage was that it was difficult to install on relatively small (especially square) roofs because of its large size.

[Problem to be solved by the invention]

The purpose of this invention is to improve the drawbacks of the above-mentioned conventional devices, and to be able to always exhibit good ventilation performance regardless of the wind direction, and to be easily installed even on relatively small-scale roofs. The purpose of the present invention is to provide a ventilation system that is small and has a beautiful appearance.

[Means to solve the problem]

In order to achieve the above object, the ventilation system of the present invention includes a plurality of columns arranged vertically or with their upper ends gathered together at an angle, and horizontal annular columns each installed in multiple stages on the outside and inside of the columns. Each louver includes a base plate parallel to the support, an inclined part connected to the upper end of the base and inclined in a direction away from the support, and an upper plate connected to the upper end of the slope and substantially parallel to the support. All of the louvers are arranged on the outside and inside of the pillars, respectively, at intervals in the vertical direction, and in such a way that the base and top plate parts of the louvers that are adjacent to each other in the vertical direction partially face each other. is fixed to the pillar. Furthermore, at the upper end of the upper plate of each louver,
Each has a continuous folded part that slopes toward the support column.

[Effect]

Because the louvers are formed in an annular shape, the ventilation function works equally well against wind in any direction, so as long as there is wind, excellent ventilation performance is always demonstrated regardless of the direction of the wind. In addition, the wind that blows along the roof curves upward along the outside of the louvers, making it difficult for wind and rain to enter the inside of the outside louvers.
Once it enters the room, it does not reach the indoor side, but instead flows downward between the outside and inside louvers.

【Example】

A first embodiment of the invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing its appearance, and FIG. 2 is a longitudinal sectional view thereof. Around the ventilation window formed on the roof 1 of the building,
(For example) Four pillars 2 are arranged vertically at equal intervals, and horizontal circular louvers 3 and 4 are attached to the outside and inside of the pillars 2 in multiple stages (for example, five stages each) at predetermined intervals. , on which a circular roof member 5 is provided. The louvers 3 and 4 are made of synthetic resin, metal, or the like, and each has an annular cross-sectional shape as shown in FIG. The louver 3 provided on the outside of the pillar 2 has a base plate portion 3a parallel to the pillar 2.
, an inclined portion 3 b connected to the upper end thereof and inclined outward (in a direction away from the support column), and an upper plate portion 3 c connected to the upper end thereof and substantially parallel to the support support column 2 . Furthermore, the louver 4 provided inside the column 2 has a symmetrical cross-sectional shape with respect to the louver 3 and the column 2, and has a base plate portion 4 parallel to the column 2.
a, an inclined part 4b connected to its upper end and inclined inwardly (that is, in a direction away from the support column), and an upper plate part 4c connected to its upper end and substantially parallel to the support support 2. The louvers 3 provided on the outside of the pillars 2 are arranged at a predetermined interval in the vertical direction, and the upper plate portion 3c of the louver adjacent to the lower side partially overlaps the base portion 3a of the louver located on the upper side. The substrate portion 3a is placed so as to face the pillar 2 (for example).
It is fixed with screws. The louver 4 provided on the inside is also arranged in a similar positional relationship (symmetrically with respect to the column 2). Because the ventilation system has a cylindrical shape,
No matter which direction the wind blows from, the wind will hit the center of the ventilation system from the front, so the ventilation function will work exactly the same regardless of the direction of the wind. Always exhibits excellent ventilation performance regardless of the situation. In addition, since the wind blowing along the roof 1 curves upward as shown by the arrow, it is difficult for wind and rain to enter the inside of the outer louvers 3, and even once they do, they do not reach the indoor side due to the presence of the inner louvers 4. Since the water does not enter and flows downward between louvers 3 and 4, the rain is kept out very well. Note that the louver 3 provided on the outside of the column 2 and the louver 4 on the inside may be provided at symmetrical positions as shown in FIG. 2, or in the second embodiment shown in FIG. They may be provided alternately, such as. 4 and 5 are a perspective view and a longitudinal sectional view of the third embodiment. The four pillars 2 provided around the ventilation window are arranged at an angle so that their upper ends are gathered together, and the pillars 2
Horizontal circular louvers 3, 4 on the outside and inside of
is attached in the same manner as in the first embodiment, and a conical roof member 6 is provided thereon. As shown in FIG. 2, the cross-sectional shapes of the louvers 3 and 4 are inclined inwardly in accordance with the inclination of the support column 2, and the diameter of the louvers becomes smaller as they go upward.
The outer louver 3 includes a base plate part 3a, an inclined part 3b, and an upper plate part 3c similar to those in the first embodiment, and further has an inner side (on the support column 2 side) connected to the upper end of the upper plate part 3c. It is provided with a short inclined folded part 3d. Also, the inner louver 4 is different from the outer louver 3.
The base plate portion 4a, the inclined portion 4b, and the upper plate portion 4 are symmetrical to
In addition to c, a short folded portion 4d that slopes outward (toward the support column 2) is connected to the upper end of the upper plate portion 4c.
It is equipped with Because the ventilation device has a conical shape, the wind hits the central part of the ventilation device from the front, so it always exhibits excellent ventilation performance regardless of the wind direction, just like the previous example. Regarding rain protection, since the louvers 3 and 4 are provided with the folded portions 3d and 4d, it is even more difficult for wind and rain to enter than in the previous embodiment, which is extremely good. In addition, the louver of this example equipped with a folded part is
A louver without a folded part can be used in a ventilation system with vertical supports as in the previous example, or a louver without folded parts can be used in a ventilation system with sloped supports as in this example. Needless to say, it's a good thing. Further, in each of the above embodiments, a circular louver is used, but the louver is not limited to this. If it is, exactly the same effect can be expected.

【Effect of the invention】

As explained above, the ventilation system of the present invention is
Since the ventilation system is equipped with an annular louver, the ventilation function works equally well regardless of the direction of the wind, so unlike conventional equipment that is formed in a panel shape, the ventilation system works regardless of the wind direction. If there is, it will always exhibit excellent ventilation performance, and once it does, it will not enter the inside of the louver and will flow downward between the inside and outside louvers, rather than entering the room, making it extremely effective at shutting out rain. Since it is small, it can be easily installed on the roof of a relatively small-scale leisure facility, and it also has a beautiful appearance and an excellent design. Further, by using a structure in which the upper end of each louver is provided with a folded portion that slopes toward the support column, it is possible to further improve rain protection.
