There is an effect.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. First, the first embodiment shown in FIGS. 1 to 7 will be described. What is shown there is a ventilator configured for attic ventilation, which consists of a body part and a draining part as shown in FIG. It comprises a support plate 2 for supporting the main body cover 1 and end face closing plates 3 for closing both end faces of the main body cover 1. This ventilation unit is usually formed symmetrically in the width direction and the length direction.

  The main body cover 1 has a mountain shape having an upward inclined surface 4 having a gradient corresponding to the ridge, and the upper inclined surface 4 is bent downward in the middle to form a downward inclined surface 5. On the upper inclined surface, an outer ventilation surface 6 is formed which is formed with a large number of long holes, circular holes, lattices, and other appropriately shaped ventilation holes. The outer ventilation surface 6 fulfills a certain amount of rain / snow invasion prevention function, but is primarily for ensuring air permeability, and has an opening area that does not impede air permeability.

  The upper end of the support plate 2 is fixed to the back surface near the upper end of the upper inclined surface 4, and the lower surface thereof is bent to form the contact surface 7 that contacts the roof material 31. The end of the contact surface 7 is bent and extended, and the end of the extended surface 8 is fixed to the lower end of the back surface of the downward inclined surface 5. A drain hole 9 is appropriately formed in the extended surface 8. A waterproof packing 24 extending in the length direction is fixed to the back surface of the contact surface 7 as necessary. The waterproof packing 24 functions to prevent rainwater from entering between the contact surface 7 and the roof material 31.

  An inner ventilation surface 10 is formed in the middle portion of the support plate 2 by forming numerous small holes of appropriate shapes. The size of the small hole of the inner ventilation surface 10 is smaller than the ventilation hole of the outer ventilation surface 6, and in the case of a circular hole, for example, the diameter is about 0.5 mm to 3 mm. To do. This size is a size that can be ventilated without passing water droplets.

Although the support plate 2 shown in FIG. 2 is divided into left and right parts, the upper end can be extended and integrated. Further, in order to retain the shape of the support plate 2, and the main body cover 1, a chevron-shaped reinforcing material 16 is disposed along the end portion of the support plate 2 or the back surface of the end portion and an appropriate place in the middle. Sometimes.

  The main body cover 1 is designed so that the lower end of the lower inclined surface 5 is kept slightly lifted from the roof material 31 when it is supported on the support plate 2 and installed on the ridge, and drains there. A gap 11 is secured.

  The end face closing plate 3 closes both ends of the main body cover 1 and is integrated with the main body cover 1. A fixing plate 12 extending outward is extended at the lower end of the end surface closing plate 3, and the fixing plate 12 is fixed to the roof material 31 by nail fastening, screwing or the like, whereby the main body cover 1 and the support plate 2. Is mounted on the ridge.

  The drainer 13 is composed of a rising surface 14 and a fixed surface 15 extending obliquely downward from the lower end of the rising surface 14 corresponding to the inclination of the roofing material 31, and a pair of water drains 13 are arranged across an opening 32 provided in the ridge. The drainer 13 is fixed to the roof material 31 through the fixing surface 15. The drainer 13 may be integrated with the support plate 2 and the main body cover 1 by a method such as fixing the fixing surface 15 to the back surface of the contact surface 7 of the support plate 2.

  As the height of the rising surface 14 is higher, the waterproof effect is increased, but the ventilation performance is decreased. Therefore, preferably, the uppermost point B of the inner ventilation surface 10 is equal to or below the line aa connecting the uppermost point A of the rising surface 14 and the lowermost point C of the outer ventilation surface 6. Designed. In such a positional relationship, rain and snow that has entered from the outer ventilation surface 6 passes through the inner ventilation surface 10 and enters the back of the hut beyond the rising surface 14 of the drainer 13 without reducing the ventilation performance. Is definitely avoided.

  3 to 7 show a construction method of the present ventilation device. The method will be described. First, an opening 32 is provided in the ridge portion of the field board 33 (FIG. 3), the rising surface 14 of the drainer 13 is taken out from the opening 32, and the inclined surface 15 of the drainer 13 is provided between the roof 31 and the roofing. The drainer 13 is fixed by being pinched between the base plate 33 or by striking the base plate 33 from the base plate 33 to the rafter 35 (FIG. 4).

  Subsequently, the main body cover 1 and the support plate 2 attached thereto are placed on the drainer 13 (FIG. 5), and fixed on the roof material 31 via the fixing plate 12 (FIG. 6). Then, the wrapping 34 is arranged on the ridge, and the gap between the ridge wrapper 34 and the end face closing plate 3 is waterproofed and finished by sealing (FIG. 7).

  In the ventilating apparatus installed as described above, outside air that has flowed in from the outer ventilation surface 6 on one side during a weak wind passes through the inner ventilation surface 10, passes the air inside the shed behind the drainage 13. While being pulled out, it passes through the inner vent surface 10 and the outer vent surface 6 on the opposite side. At that time, most of the rain and snow passing through the outer ventilation surface 6 falls downward without passing through the inner ventilation surface 10, flows along the support plate 2, and flows from the drain hole 9 of the extended surface 8 to the roof material 31. It falls and comes out of the drain gap 11. Even if there is rain and snow passing through the inner ventilation surface 10, it cannot cross the rising surface 14 due to the height of the rising surface 14, and falls down on it.

  Further, during strong wind and rain, a lot of rain and snow is blown into the outer ventilation surface 6, but many of them cannot pass through the inner ventilation surface 10 of the small hole group and fall along the support plate 2, The rain and snow that has passed through the inner ventilation surface 10 flows down on the roof material 31 without being able to cross the rising surface 14 as described above.

  Next, a second embodiment shown in FIGS. 8 and 9 will be described. In this second embodiment, the present ventilator is used as an exhaust tower for indoor ventilation. The configuration of the draining portion is different from that of the first embodiment, and the other configurations are the same. A description of the components will be omitted.

  The rising surface 18 of the drainer 17 in the second embodiment extends below the opening 32, and the fixing surface 19 is installed in the middle of the rising surface 18. A chamber 21 connected to an exhaust duct 20 for indoor ventilation is attached to the lower end of the rising surface 18. Although the attachment method is arbitrary, in the illustrated example, the lower end portion of the rising surface 18 is folded inward to form the receiving portion 22, and the upper end of the long side surface of the chamber 21 is folded outward to fold the hanging portion 23. The hanging portion 23 is formed and can be hooked on the receiving portion 22. The exhaust duct 20 is connected to an exhaust fan.

  In addition, it is good also as fixing the front-end | tip of the exhaust duct 20 directly in the opening 32 or the drainer 17 through a connection member suitably, without using the chamber 21. FIG.

  In the case of this second embodiment, in addition to the rain / snow invasion preventing action similar to that in the first embodiment, there is an action / effect that indoor ventilation is promoted through the exhaust duct 20 extending from the room.

The third embodiment is also for an exhaust tower for indoor ventilation. In this case, the exhaust fan 25 is installed on the rear surface of the field board 33 or the rafter 35 in the immediate vicinity of the opening 32, and the exhaust port 25 a is directed to the opening 32. (See the phantom line portion in FIG. 2 ). As the drainer 13 in this case, a type in which the fixed surface 15 is extended to the lower end of the rising surface 14 is used.

  The operations and effects of the third embodiment are the same as those of the second embodiment.

  In the fourth embodiment, the ventilator is provided with both a roof ventilation function and an indoor ventilation function. As shown in FIG. 10, the first method for that purpose is to install one or more partition plates 27 in the main body cover 1 to divide the main body cover 1 into several chambers. A function of either a ventilation function or an exhaust function of room ventilation is provided.

In the example shown in FIG. 10, the middle compartment is connected to an exhaust fan 26 for indoor ventilation, and serves as an exhaust function for indoor ventilation, and the compartments on both sides serve as a roof ventilation function. The configuration of each compartment is in accordance with each of the above embodiments. Along with the installation of the partition plate 27, the support plate 2 and the drainer 13 (17) are also divided according to the number of the partition plates 27.
The partition plate 27 is arranged only in the support plates 2 and 2, only the inside of the support plates 2 and 2 is partitioned into a plurality, and the space between the main body cover 1 and the support plates 2 and 2 is open. You can also.

  As another configuration for providing both of the above functions, the inside of the main body cover 1 is opened without partitioning, and in the configuration of the first embodiment, the tip of the chamber 21 or the exhaust duct 20 is placed in the opening 32 or the drainer 13. It is conceivable to fix it inside (second embodiment) or to install the exhaust fan 25 on the field board 33 or the rafter 35 (third embodiment).
