【Example】
Hereinafter, embodiments of the ventilation member of the present invention will be described with reference to the drawings.
In FIG. 1, the code | symbol 1 is a member for ventilation. This ventilation member 1 is formed by extruding resin, and is attached to the eaves back 3 of the roof 2 along the wall of the building. As shown in FIG. 2, the ventilation member 1 includes a ventilation part 4 and an opening / closing part 5 connected to the ventilation part 4. The ventilation portion 4 is formed with a connecting portion 7 that is fitted and connected to the edge of the eaves ceiling material 6. Moreover, this ventilation part 4 is formed in the convex shape in which the cross-sectional shape protruded below, and as shown in FIG. 3, a plurality of ventilation holes 8 extend in the longitudinal direction on the side surface on the building side. Is formed.
[0010]
Further, as shown in FIG. 4, the end portion of the ventilation portion 4 is a locking portion 11 formed in a saw-tooth shape, and the locking portion 11 is fitted to the opening / closing portion 5. The joint 12 is fitted and connected .
The opening / closing part 5 is fixed to the rafter 14 by a nail 13, for example, and an opening / closing valve 15 is provided at one end thereof. The on-off valve 15 is formed of a flexible resin, is extruded integrally with other parts, and is disposed at a position facing the ventilation hole 8 in the recess of the ventilation part 4. ing. When this on-off valve 15 is elastically deformed and swings in the direction of arrow A in FIG. 2 (the state indicated by the one-dot chain line in FIG. 2), it comes into contact with the valve seat 16 formed in the ventilation section 4. ing.
[0011]
According to the ventilation member 1 having the above structure, for example, when rainwater is likely to be blown from the ventilation hole 8 during wind and rain, the opening / closing valve 15 is swung by the wind pressure, and the opening / closing valve 15 is moved to the valve seat of the ventilation unit 4. By abutting and closely contacting 16, the flow path from the ventilation hole 8 to the inside of the attic is blocked, and the blowing of rainwater is reliably prevented. That is, good air permeability in the attic can be ensured without allowing rainwater to enter the attic.
Furthermore, since the opening / closing part 5 having the opening / closing valve 15 provided at a position facing the ventilation hole 8 is a separate body that is detachably connected to the ventilation part 4, the ventilation hole 8 of the ventilation part 4 is formed. At this time, the on-off valve 15 does not get in the way, so that the ventilation hole 8 can be easily formed by punching, and the manufacturing cost can be reduced.
[0012]
Furthermore, since the on-off valve 15 is integrally formed by extrusion molding on the on-off portion 5, the manufacturing cost can be reduced as compared with the case where a separate on-off valve 15 is attached.
Moreover, since the ventilation part 4 is formed in the convex shape which protruded below, and the ventilation hole 8 is formed in the side surface at the side of a building, it is hard to see the ventilation hole 8 from the outside, and a favorable external appearance is ensured. can do.
[0013]
In addition, in the said Example, although the fitting part 12 of the opening / closing part 5 which the latching | locking part 11 of the ventilation part 4 fits was protruded, it fits along the surface of the opening / closing part 5 as shown in FIG. The portion 12 may be formed, the end portion of the ventilation portion 4 may be bent, and the engaging portion 11 formed on the distal end side may be fitted and connected. In this case, the structure of the fitting portion 12 is It can be simplified.
In the above embodiment, the ventilation member 1 is provided on the wall side of the back of the eaves, that is, on the root side of the roof 2. However, the ventilation member 1 is disposed on the front side of the roof 2, that is, on the eaves side. In this case, the connecting portion 7 connected to the eaves ceiling material 6 is formed on the opening / closing portion 5 side.
In the above embodiment, the valve seat 16 with which the on-off valve 15 abuts is formed on the ventilation unit 4 side, but the flow path is blocked by simply abutting the on-off valve 15 against a part of the ventilation unit 4. You may make it.
