Description

[Detailed explanation of the invention] This invention is installed in the ventilation opening on the wall under the ridge of a house.
This invention relates to the improvement of a ventilation opening frame for a building with a hood to ventilate the attic space and prevent the intrusion of rain and snow.

Conventionally, the above-mentioned ventilation opening frames for buildings with hoods have a structure that allows rain and snow water blown into the hood to flow out from the front side of the opening frame, so rainwater, etc. is transmitted through the outer wall of the house where the opening frame is installed. It fell downward and made the exterior wall look extremely unsightly. The present invention aims to provide a ventilation opening frame for a building with a hood that allows rainwater etc. blown into the hood to drain and fall between the opening frame and the outer wall surface of the house. Another object of the present invention is to form an eave on the top of the hood to ensure that rain and snow blown into the hood are discharged to the outside.

An embodiment of the present invention will be described below based on the drawings. Figure 1 is a front view of the invention, Figure 2 is a partially cutaway rear view of the invention, and Figure 3 is a plan view of the invention. be. Reference numeral 1 denotes a building ventilation frame body installed in a ventilation hole on the lower wall of a house; 14 denotes a hood body provided on the back of the building ventilation frame body 1;
This invention is based on this building ventilation frame body 1 and hood body 1.
4, and the materials of both do not matter,
In the embodiment, it is molded from plastic.

This building ventilation frame main body 1 has a central longitudinal bar 5a in the vertical direction at the center, and vertical bars whose lengths are gradually shortened from the central longitudinal bar 5a toward both left and right ends are arranged at appropriate intervals. A plurality of vertical bars 5 are arranged in a row to form a vertical bar 5. On the back of the upper and lower parts of the vertical bar 5, there is an upper inclined bar 3 that slopes upward from the vertical bars 5b, 5b at both left and right ends of the vertical bar 5 toward the center vertical bar 5a, and a lower slope that slopes downward. An inclined bar 4 is formed, and the upper and lower inclined bars 3, 4 face each other with a constant gap 6, 6 at the central longitudinal bar 5a. The vertical beam 5 is formed of a circumferential wall 7 that is open only in the rear direction, and has a cross-sectional shape of approximately pentagon in the embodiment. The upper and lower inclined crosspieces 3 and 4 are also formed to have a U-shaped cross-sectional shape that opens toward the back, but are not limited to this shape, and are simply a single flat-shaped cross section. It may be formed like a fence rail, and the upper inclined rail 3 mainly serves a design function. The inclined bars 3, 4 are provided with protruding pieces 9, 9, .

In addition, the central part of the back surface of the vertical beam 5, that is, the upper
A hood mounting frame 10 is formed in a portion surrounded by the downwardly inclined crosspieces 3 and 4, and has a rectangular flat frame plate projecting outward from the rear surface.At least the lower frame plate 11 of this hood mounting frame 10 is Similar to the above-mentioned inclined bars 3 and 4, projecting pieces 12 are provided to extend into the cavity 8 of the vertical bar 5. The protruding piece 12 of the lower frame plate 11 of the hood mounting frame 10 is provided with drain holes 13, 13, . . . which are vertical through holes.

The hood body 14 has a substantially box-shaped body 16 that protrudes rearward from the inside of the hood mounting frame 10.
Louver wings 23, 23... are provided on the front surface of the opening of the body 16.
It is formed by arranging a plurality of them in a row in the vertical direction.

The body part 16 has a central part 17 in both sides slightly recessed in the front direction to form step parts 17a, 17a, and an upper surface plate 1 of both sides 18, 18 of the body part 16.
9 and 19 are provided with grid-like ventilation holes 20 and 20. Further, a rainwater return plate 22 is formed on the back surface of the back plate 21 below the ventilation holes 20, 20. Note that this rainwater return plate 22 may also be formed on the central portion 17 of the back plate 21.

Further, a through hole 24 is provided in the lower end louver blade 23a of the louver blades 23, 23, . . . .

15 in the figure shows the hood body 14 attached to the hood mounting frame 1.
This is a collar for attaching to the body part 16, and is provided around the outer peripheral edge of the body part 16.

When the hooded building ventilation frame constructed as described above is installed on the wall of a house, rain and snow water that passes through the louver blades and accumulates inside the hood body 14 will flow as shown by the arrow in Figure 5 of the drawing. Through holes 13 are connected to the hood mounting frame 10 from the bottom plate 25 of the hood body 14 through the through holes 24 of the lower end louver wings 23a, and are provided in the protruding pieces 12, 12, . . . of the lower frame plate 11 of the hood mounting frame 10. The protruding pieces 9, 9 of the lower inclined crosspiece 4 pass through the projecting pieces 9, 9...
The water can fall from the inclined bar 4 to the ground through the gap 6 of the inclined bar 4. Therefore, unlike conventional ventilation frames for buildings with hoods, rainwater accumulated inside the hood is not drained from the outside of the front of the ventilation frame, polluting the wall surface, but instead of being installed on the wall. The present invention allows water to drain from between the ventilation opening frame body 1 and the wall surface.
Rainwater, etc. from the hood falls directly to the ground through the gap 6 of the inclined crosspiece 4, and there is no risk of staining the wall surface to which the house is attached.

In addition, the present invention provides ventilation holes 20, 2 formed in the top plates 19, 19 of both sides 18, 18 of the body 16.
Since the rainwater return plate 22 is formed on the back surface of the lower back plate 21, the louver wings 23, 23
The rain and snow water that has passed through and blown into the hood body 14 hits the rainwater return plate 22 and can reliably prevent rain and snow water from entering the attic through the ventilation holes 20, 20 of the hood body 14. .

In addition, the body part 16 of the hood body 14 of the present invention has the central part 17 in both sides slightly recessed in the front direction, and the stepped part 1
7a, 17a, even if there is a bundling post on the wall where the ventilation opening frame is attached, the bundling post can be inserted into the central part 17, and the bundling post can be inserted into the stepped part 17a, 17.
If the vent frame for a building according to the present invention is installed in such a manner that it is held in place by the brackets a, even a large vent frame that spans both sides of the bundle pillar can be installed very easily and easily, as in the present invention.
