Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a roof ventilation system with a new configuration that is installed at the ridge of various roofs.

To explain its purpose in more detail, it is a ventilation system installed on various types of roofs such as slate roofs whose main purpose is to prevent condensation.Especially during storms, heavy snowfall, and heavy rain areas, the purpose is to pursue perfection in preventing rain.
Moreover, the present invention provides a roof ventilation system with a simple structure and excellent workability.

[Conventional technology and problems]

Conventionally, various roof ventilation devices of this type have been developed and installed on the roof.

However, if the rain cover is not perfect, it will not be possible to prevent the infiltration of rainwater or snow water, and the problem will be that the purpose cannot be achieved.

In addition, conventional ventilation devices are comprised of a plurality of parts, and their installation is troublesome, resulting in poor workability.

[Means for solving problems]

The present invention solves the above-mentioned conventional problems, and its purpose is to provide a roof ventilation system with a simple structure that pursues perfect rain control and is easy to install.

In order to achieve this purpose, the roof ventilation device of the present invention has an arm section extending outward at the upper end of an upright main body, and a slope substantially equal to the roof through a circular arc section at the lower end, extending outward. , a pair of supports each having a mounting portion that can be fixed to the roof, and further comprising an extending portion that extends outward through a drooping stepped portion provided at the tip of the mounting portion and having a drainage portion at the tip. The material is installed on the ridge of the roof with a ventilation path, and the upright parts of the aggregate are superimposed on the main body of this support material and attached via screw rods and nuts, and then suspended from both sides of the aggregate. A symmetrical sloped part forming a side part is provided, a protruding part with a gentle slope is formed inward from the lower end of the side part, and a folded part is provided at the lower end part, and an opening is provided. It is characterized in that a ridge member forming a bent portion is fitted and fixed.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a longitudinal sectional view showing the installed state of the present invention;
Fig. 2 is a perspective view of the ridge member, Fig. 3 is a perspective view of the support member, Fig. 4 is a perspective view of the aggregate, and Fig. 5 is a perspective view of the cap.

In the figure, reference numeral 1 denotes a ridge member, which forms sloped parts 2, 2 with symmetrical gently sloped surfaces, and side parts 3, 3 that hang down from both ends of the sloped parts 2, 2, respectively. .

Further, protrusions 4, 4 with gentle slopes are formed inward from the lower ends of the side parts 3, 3, respectively, and the tips of the protrusions 4, 4 are made to hang down, respectively, and folded parts 5, 5 are formed at the lower ends. The oppositely facing bent portions 6, 6 are formed, respectively, and the oppositely facing bent portions 6,
An opening 7 is formed between the holes 6 and 6.

Reference numeral 10 denotes a pair of supporting members, which connect the ridge member 1 to the roof 2.
This is for installation on the ridge part 21 of the ridge member 1, and an arm part 12 facing the outside of the slope, which is slightly stronger than the slope part 2 of the ridge member 1, is formed at the upper end of the upright main body 11, and an arcuate part is formed at the lower end. A mounting part 14 is formed which extends outward on a slope substantially equal to the roof through a mounting part 13, and a drainage part 16 with a slope substantially equal to that of the mounting part 14 is provided at the tip of the mounting part 14 extending outward via a step part 15 that hangs down. An extended portion 17 is configured.

Thus, the ridge members 1 are installed on the ridge portion 21 of the roof 20 at predetermined intervals via the supporting members 10, 10 having the above configuration.

In other words, members 22, 22 are interposed on the ridge 21, and nails 23, 24 are attached to the mounting portion 14 and the stepped portion 15, so that the arm portions 12, 12 are positioned outwardly, respectively, and in accordance with the spacing S ₁ of the ridge 21. , a ventilation hole S ₂ is provided and the supports 10, 10 are fixed to the roof 20.

Then, the upright portions 31 of the U-shaped aggregate 30 having a cross-sectional material etc. arranged thereon are respectively superposed at three locations at the front and rear ends and the central portion of the main body 11 of the supporting members 10, 10,
Pass the screw rod 32 through the screw hole 18, and insert the nut 33,
33, the aggregate 30 is attached to the supporting members 10, 10, respectively.

This aggregate 30 has an upright portion 31 as shown in FIG.
The structure has a U-shape in which a top part 34 that is equal to the slope part 2 of the ridge member 1 extending outward from the upper end is formed, and a bent part 35 that hangs down from the tip of the top part 34 is formed.

In this way, aggregate ₃₀ ,
30 is attached to support the ridge member 1.

Specifically, as shown in FIG.
35, the side parts 3 and 3 are overlapped, respectively, and vent holes _S4 and _S4 are provided on both sides downwardly to form the bent part 35 and the side part 3.
One or more rivets 36 are applied to the ridge member 1, and the ridge member 1 is installed on the ridge portion 21.

Reference numeral 40 denotes a movable plate which is pivotally supported to be openable and closable via hinges ₄₁ at the tips of the arms 12 of the support member 10. When there is wind pressure such as a large amount of air entering, the wind pressure pushes the movable plate 40 upward and brings the tip of the movable plate 40 into contact with the bent part 35 of the aggregate 30, thereby opening the ventilation path _S4 . Closed tightly,
It is constructed to prevent air from entering.

In normal cases, this movable plate 40 is suspended in a substantially hanging shape due to its own weight, and the air in the attic passes through the interval _S1 and above the ventilation path _S2 , the airflow path _S3 separates into two directions. , _S3 , and are exhausted to the outside from ventilation paths _S4 and _S4 , respectively.

In the figure, 42 is a rope provided near the top of the ridge member 1 to prevent insects from entering, and 43 is a cover placed over the front and rear openings of the ridge member 1.

[Effect of idea]

If the roof ventilation system of the present invention has the above configuration, it will have the following effects.

The ventilation passage _S4 of the present invention is formed by the upright main body 11 of the support member 10 and the inclined protrusion 4 facing the main body 11, so that even if rainwater or snow enters the ventilation passage _S4 , Due to the outwardly inclined arms 12 of the protruding portion 4 or the supporting member 10 located above, the space S ₁ of the ridge portion 21 is not penetrated through the air passage S ₃ .

When a large amount of air enters, the movable plate 40 pivotally supported on the arm 12 automatically closes due to wind pressure, thereby preventing wind, rain and snow from entering.
The rain performance will be perfect.

In addition, ventilation channels S ₃ and S ₄ provided in the ridge member 1 of the present invention
is in the relationship S ₃ < S ₄ , and the air in the attic is
Since the air flows from _S1 through the narrow-opening ventilation path _S3 to the wide-opening ventilation path _S4 , the air is exhausted smoothly and does not stagnate in the attic.

Moreover, the arcuate portion 13 of the support member 10 has the tolerance to accommodate the slope of the roof 20.

On the other hand, outside air is passed through the wide opening ventilation path S ₄
Therefore, in conjunction with the structure of the ridge member ₁ and support member 10 and the structure of the rotating plate 40 that can be opened and closed, it is possible to prevent wind, rain and snow from entering. Even when used in areas with heavy snowfall or heavy rain, the rain protection is perfect.

Furthermore, the roof ventilation system of the present invention has a simple structure that can be roughly divided into a ridge member 1, a support member 10, and an aggregate 30, and has a small number of parts, and has advantages such as easy assembly and construction. It is something that you have.
