Description

[Detailed Description of the Invention] The present invention relates to an attic ventilation system particularly for a roof having a ridge such as a gable, hipped roof, hipped roof, etc.

Conventionally, measures have been taken to ventilate the attic, such as providing a louver or ventilation hole in the side wall of the attic, or providing a ventilation hole on the lower surface of the eaves.

However, none of these methods were able to sufficiently ventilate the attic. In other words, the hot air and odors in the attic heated by strong sunlight,
Even though it stays just below the ridge, which is the top of the roof,
Conventional attic ventilation relies on air flowing in from the sides of the attic and air flowing into the lower part of the attic from the eaves, and the amount of air flowing in from these sources is extremely small unless there is a particularly strong wind. ,
It only serves to slightly dilute the heat and odor in the attic. Conventional ventilation methods can improve the problem to some extent by installing a large number of them over a wide area to increase the amount of air flowing into the attic, but this also has its limits when considering the flow of rainwater and the structure of the building. Particularly in the case of a hipped roof, the attic has a structure with almost no side walls, so it is extremely difficult to obtain sufficient ventilation of the attic using conventional ventilation means.

This invention solves these conventional drawbacks by perfecting ventilation in the attic, thereby preventing indoor temperature rise due to the accumulation of hot air and odors, dew condensation in the attic, and the occurrence of indoor odors. That is.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention. Along the roof ridge, two wooden supports 2 facing each other with an appropriate interval are placed on a barrel tree 1. It is installed so that it protrudes. This tree receiver 2
The upper end of the roof material 3 is bent upward to form a raised part 4 along the outer surface of the roof member 3, and further outside the raised part 4, there are legs 6 of a rain gutter 5 that covers the upper surface of the tree receiver 2.
is covered.

The rain cutter 5 is a member that has a symmetrical shape and extends along the tree receiver 2, and covers the upper surface of the tree receiver 2, leaving an open path 7. Further, the outer end of the rain cutter 5 protrudes outward from the tree receiver 2 and is folded back downward to form an overhanging portion 8.
The leg portion 6 is formed by extending downward from the base along the outer surface of the support tree 2 and further protruding its tip portion diagonally downward toward the roof material 3.

On the rain gutter 5, inner frames 9 forming a substantially gate shape are fixed at appropriate intervals along the tree receivers 2, and a cover 10 forming a substantially inverted U-shape is attached to the rain gutter 5 from above.
A ventilation passage 11 is formed between the rain cover 5 and this cover 10. Therefore, the ventilation passage 11 is communicated with the attic through the space between the support trees 2 and the open channel 7. And ventilation passage 1
At least one end of the attic 12 is open to the outside through a louver (not shown) to prevent rain water from blowing in, and the hot air and odors in the attic 12 are absorbed into the ventilation passage 7 by their natural upward force. is discharged from.
Furthermore, a heat insulating and sound absorbing material 13 such as urethane foam is attached to the inner surface of the cover 10. This heat-insulating and sound-absorbing material 13 is for preventing dew condensation on the inner surface of the cover 10, and also for preventing the sound of rain, especially when the cover 10 is constructed of an iron plate or the like.
The inner frame 9 serves to support the cover 10, and is preferably shaped to follow the inner surface of the cover 10 as much as possible.

Both sides of the cover 10 are once folded inward to form an eave part 14, and both lower ends are bent outward in a U-shape to form a package that is hung on the overhang part 8 of the rain gutter 5. It has become a holding part 15. The lower end of the holding part 15 extends slightly downward along the outer surface of the wooden receiver 2, and the tip is folded back inward to form a drainer 16. This drainer 16 maintains a gap between the legs 6 of the rain drainer 5 to prevent water from being sucked up by capillary action.
Further, an inner frame 9 is provided inside the eave portion 14 of the cover 10.
A protruding portion 17 formed in the eaves portion 14 is inserted thereinto and engages with the inner and lower surface of the eave portion 14 .

To explain how to attach the cover 10 according to the present invention, the cover 10 is made of a metal plate such as iron, copper, or aluminum or synthetic resin, and when attached, the cover 10 is made by pushing both sides to the left or right using its elasticity. It is installed by spreading it out, inserting the protruding part 17 into the eave part 14, and fitting the protruding part 8 into the enclosing part 15. If attached in this way, the elasticity of the cover 10 can provide a clamping action, and the inner lower surface of the eave part 14 and the protruding part 17
The cover 10 can be easily attached without using any special fixing means by engaging the holding part 15 with the overhanging part 8. In particular, when it is necessary to prevent the cover 10 from rattling during strong winds, etc., the cover 10 may be glued to the inner frame 9, the cover 10 near the drain 16 may be nailed to the tree receiver 2, or the cover 10 may be wrapped. Measures such as caulking the holding portion 8 to the overhanging portion 8 of the rain cutter 5 can be taken. Also, when performing the above nailing,
The overhanging part 8 of the rain cutter 5 and the holding part 15 of the cover 10 protrude above the nailing part, and since rainwater is rarely splashed directly onto the nailing part, there is no need to worry about rain leaking from here. do not have. If particularly necessary, the projecting portion 8 and the holding portion 15 may be bent downward after nailing so as to cover the nailing portion. Furthermore, the holding part 15
A small hole for draining water can also be provided at the tip.

If the ventilation system is configured in this way, the hot air and odor in the attic 12 that accumulates directly under the ridge will be discharged through the ventilation passage 11 due to its natural upward force, and the air in the attic 12 will be It can always be kept fresh and clean. Furthermore, since almost no nailing part is exposed to the outside, the durability of the roof will not be reduced by providing this device. Rather, this device not only extends the life of the roof by preventing condensation, but also has the advantage of giving the ridge a solid appearance, making it extremely aesthetically pleasing.

Next, rain drainage will be explained with reference to FIG.

As mentioned above, the rain gutter 5 is a member that covers the upper surface of the tree catcher 2, and even if rainwater intrudes into the cover 10, it prevents it from directly entering the attic 12, and also prevents it from directly entering the attic 12. This is to prevent the hot air and odors that have entered the room from flowing back into the attic 12.

Any type of rain drainer 5 may be used as long as it can cover the upper surface of the tree receiver 2 while leaving an open path 7, but in order to improve drainage, it is preferable that the upper surface be sloped in both directions.

As shown in FIG. 2a, the method for forming the open channel 7 is to divide the rain cutter 5 into two in the longitudinal direction, bend the inner part upward at an acute angle to form the raised part 18, and make the cross section approximately C. It is best to fit both legs of the shaped cap 19 into the raised portion 18, leaving an opening 7. In this case, by sliding the cap 19, there is an advantage that the position of the open circuit 7 can be arbitrarily determined, and positioning on the spot is easy. However, as shown in Figure 2b, the integrated rain drain 5
The raised portion 18 and the open path 7 may be formed by making an H-shaped cut in the upper surface and bending the cut portion upward. Furthermore, in either case, the raised portion 18 acts as a dam to prevent rainwater from entering the attic, and the opening 7 does not necessarily have to be made intermittently by fitting a cap 19 or the like. , may be formed continuously in the longitudinal direction. However, from the viewpoint of preventing backflow of hot air and odor flowing into the ventilation passage 11 from the attic 12 and waterproofing, it is preferable to limit the open circuit 7 to some extent.

FIG. 3 is a sectional view showing an example in which ventilation can be performed from the side of the cover.
Ventilation holes 20 are formed on both sides of the eaves 14 and below the eaves 14. If such a cover 10 is used, hot air and odor from the attic 12 can be more smoothly discharged. In addition, ventilation hole 20
is also protected from rain by the eaves 14, so there is extremely little risk of rainwater entering due to the provision of the ventilation holes 20. However, ventilation hole 20
It is true that it is easier for rainwater to infiltrate to some extent than from areas without
It is preferable not to form an open circuit 7 in a portion corresponding to the ventilation hole 20. In particular, when providing such a ventilation hole 20, the cap 1 is
It is convenient to adjust the position of the open circuit 7 by fitting the opening 7. It is also a preferable embodiment to form ventilation holes on the lower surface of the eaves 14 of the cover 10 in order to prevent rainwater from entering.

FIG. 4 shows another example of the combination of the inner frame and the cover in this device, in which the upper surface of the cover 10 is made into a chevron shape, and both sides of the cover are made to protrude outward in a U-shape to form an eave part 14. Accordingly, the inner frame 9 also has a chevron-shaped upper surface and a U-shaped protrusion 17 on both sides of the upper part. It is clear that the same effects as those described above can be obtained by such a combination, and it is only necessary to select it as appropriate from the design point of view. In particular, the one shown in FIG. 4 has a less strange appearance as the shape of the ridge of a Western-style roof, so the appearance can be made even better. Further, the present device can take various other shapes, and may be determined in consideration of harmony with the building.

As explained above, the present invention not only provides complete attic ventilation, extends the life of the house and improves its livability, but also does not impair the exterior appearance at all.
