Description

The present invention relates to a building ventilation port device, and more particularly, it can effectively prevent the outer wall of the building below the ventilation port from becoming dirty, looks good, and is damaged during transportation. It is related to the ventilation port device of the building that can prevent this.

Generally, when the ventilation port device is attached to a building, the part where the ventilation port device and the outer wall are in contact with each other is sealed with a caulking material in order to prevent rainwater from entering the ventilation port from between the ventilation port device and the outer wall. Is done. However, dirt easily adheres to the surface of the caulking material, and when rainwater flows on the surface of the caulking material, the dirt adhering to the surface of the caulking material is washed away by the rainwater, and when the rainwater flows down the wall surface of the building, the building There is a problem that streaky stains are generated on the wall surface.

Therefore, the ventilation port device is usually provided with a draining plate that guides rainwater flowing down on the sealing surface so as to be separated from the outer wall of the building.

When the lateral length of the vent device of this drainer is equal to the width of the vent device, it is difficult to guide the rainwater flowing down on the sealing surface to the drainer, flowing down on the outer wall of the building. Streaky stains could be formed on the outer walls of the building.

Therefore, by making the lateral length of the ventilation port device of the drainer plate larger than the width of the ventilation port device, the rainwater flowing down on the seal surface is effectively guided to the drainer plate, and the rainwater is separated from the outer wall of the building. A ventilation device has been proposed that makes it possible to guide the ventilation (for example, Japanese Patent Application Laid-Open No. 8-303830).

Japanese Unexamined Patent Publication No. 8-303830

In this way, by making the lateral length of the ventilation port device of the drainer plate larger than the width of the ventilation port device, it becomes possible to surely guide the rainwater flowing down on the surface of the caulking material to the drainer plate. However, when the lateral length of the drainer vent device is greater than the width of the drainer device, it not only looks bad, but also when transporting the ventilator device with the drainer plate attached, the drainer plate. There is a risk that the left and right ends of the ventilation port will be bent and damaged, and in order to prevent the left and right ends of the drainer plate from bending when transporting the ventilation port device, extra labor and cost will be required to pack the ventilation port device. There was a problem.

Therefore, the present invention can effectively prevent the outer wall of the building from becoming dirty due to the rainwater flowing down the surface of the caulking material, and it looks good, and the drainer plate is attached. It is an object of the present invention to provide a ventilation port device for a building that can effectively prevent the left and right ends of the draining plate from being bent and damaged when the ventilation port device is transported.

Such an object of the present invention is a ventilation port device that can be attached to the outer wall of a building and has an opening that communicates with a ventilation port formed in the outer wall, and the opening of the surface of the ventilation port device facing the outer wall. A caulking material filling portion provided at a position surrounding the upper portion and both side portions and capable of filling the caulking material that seals between the outer wall and the lower portion of the ventilation port device, and filling the caulking material filling portion. It is provided with a draining member that receives the water flowing down on the coking material and guides it away from the outer wall, and the lateral length of the ventilation port device of the draining member and the width of the ventilation port device are substantially equal to each other. Achieved by a vent device characterized in that a guide member extending diagonally upward toward the side surface of the vent device is provided at the lower end of the caulking material filling portion surrounding both sides of the opening. To.

When it rains, the rainwater that falls flows on the upper surface of the ventilation port device, and a part of it flows down on the side surface of the ventilation port device and the caulking material filled in the caulking material filling part, but on the surface of the caulking material. Since dirt easily adheres, the rainwater flowing down on the caulking material contains dirt adhering to the surface of the caulking material, and the rainwater flowing down on the caulking material is passed to the outer wall surface of the building and spreads on the outer wall surface. In the case of flowing down, streaky stains often occurred on the outer wall surface of the building. Therefore, in the conventional ventilation port device, the lateral length of the ventilation port device of the draining member that receives the rainwater flowing down on the coking material and guides it away from the outer wall of the building is made larger than the width of the ventilation port device. , It was configured to reliably receive the rainwater flowing down on the coking material by the drainage member, but in this way, when the lateral length of the ventilation port device of the drainage member is made larger than the width of the ventilation port device. Not only does it look unattractive, but when transporting the ventilation port device to which the drainage member is attached, the left and right ends of the drainage member may be bent and damaged, and when transporting the ventilation port device, In order to prevent the left and right ends of the drainage member from bending, there is a problem that extra labor and cost are required for packing the ventilation port device. However, according to the present invention, since the lateral length of the ventilation port device of the drainage member and the width of the ventilation port device are substantially equal, not only the appearance is good, but also the ventilation port device to which the drainage member is attached is carried. Since the left and right ends of the drainage member are not bent or damaged during the process, and the lower end of the caulking material filling portion is provided with a guide member that extends diagonally upward toward the side surface of the ventilation port device. Even if the length of the drainage member is substantially the same as the width of the ventilation port device, the rainwater that flows down on the caulking material and reaches the lower end of the caulking material filling portion is surely applied to the drainage member by the lower surface of the guide member. Therefore, the rainwater that has flowed down on the caulking material is passed to the outer wall surface of the building, and streaky stains caused by flowing down on the outer wall surface are generated on the outer wall surface of the building. It is possible to reliably prevent this from happening.

In a preferred embodiment of the present invention, the caulking material filling portion provided at a position surrounding both side portions of the opening portion extends in a substantially vertical direction.

According to a preferred embodiment of the present invention, the caulking material filling portion provided at a position surrounding both side portions of the opening extends in the substantially vertical direction, and the ventilation port is located at the lower end portion in the substantially vertical direction of the caulking material filling portion. Since a guide member extending diagonally upward toward the side surface of the device is provided, even if the lateral length of the ventilation port device of the drainage member and the width of the ventilation port device are substantially equal, the plumb bob flows down on the caulking material. The rainwater can be reliably guided onto the drainage member by the guide member.

In the present invention, the guide member is provided so as to have an angle of 25 degrees to 50 degrees, preferably 30 degrees to 45 degrees with respect to the side surface of the ventilation port device. If the angle of the guide member with respect to the side surface of the ventilation port device is less than 25 degrees, the width of the caulking material filling portion becomes narrow and the space between the ventilation port device and the outer wall cannot be sufficiently sealed, while ventilation. If the angle of the guide member with respect to the side surface of the mouth device exceeds 50 degrees, the rainwater that flows down on the caulking material and reaches the lower end of the caulking material filling portion may fall to the ground surface as it is, and the guide member. This makes it difficult to guide rainwater onto the drainage member as desired, which is not preferable.

As shown in FIG. 3, the base member 7 is fixed to the hood member 5 at six places by blind rivets 7a, 7b, 7c, 7d, 7e, 7f.

As shown in FIGS. 2 and 3, a draining plate forming portion 25 is formed on the lower edge portion of the base member 7. The drainer plate forming portion 25 is substantially perpendicular to the surface of the base member 7, and has a wall portion 26 having substantially the same height as the plate-shaped wall 14, and the top of the wall portion 26 is substantially parallel to the surface of the base member 7 downward. It is provided with a flat plate-shaped portion 27 extending and a draining plate 28 extending diagonally downward and forward (in a direction away from the outer wall 2) from the lower edge portion of the flat plate-shaped portion 27. As shown in FIG. 3, the lateral length of the ventilation port device 1 of the draining plate 28 is set to be substantially equal to the width of the hood member 5.

The draining plate 28 guides the rainwater that has flowed down on the draining plate 28 so as to be separated from the outer wall 2, and as shown in FIGS. 2 and 3, both side portions 28a and 28a of the draining plate 28 are It is bent at a substantially right angle to the surface of the draining plate 28 to prevent rainwater that has flowed down to the draining plate 28 from flowing sideways, and at the same time, the strength of the draining plate 28 is improved.

Further, as shown in FIG. 3, the upper edge portions 28b and 28b on the outer wall 2 side of the draining plate 28 are bent so as to be substantially parallel to the surface of the base member 7, and the rainwater that has flowed down to the draining plate 28. Is prevented from flowing down to the outer wall 2 side, and the strength of the draining plate 28 is improved.

As shown in FIG. 2, a garage 30 is fixed to the vicinity of the lower edge portion of the base member 7 by screws 32a and 32b.

As shown in FIGS. 2 and 3, guide members 35 and 35 extending diagonally upward are formed in the caulking material filling portion 15 at the left and right ends of the wall portion 26 of the draining plate forming portion 25, respectively. There is. In this embodiment, the guide members 35 and 35 are formed at an angle of 40 degrees with respect to the plate-shaped wall 14.

FIG. 4 is a schematic rear view of a ventilation port device showing a state in which the caulking material is filled in the caulking material filling portion 15.

As described above, when the ventilation port device 1 is attached to the outer wall 2 of the building, the caulking material filling portion 15 is filled with the caulking material. As shown in FIG. 4, the caulking material is placed in the caulking material filling portion 15 at the same height as the plate-shaped wall 14 formed in the hood member 5 around the opening 11 in a substantially rectangular shape. The seal portion 18 is formed by filling the cross section so as to have a substantially rectangular shape.

The guide members 35 and 35 do not necessarily have to be formed so as to form an angle of 40 degrees with respect to the plate-shaped wall 14, and the guide members 35 and 35 are 25 to 50 degrees, preferably 30 degrees. It has an angle of 45 degrees. When the angle of the guide members 35 and 35 with respect to the plate-shaped wall 14 is less than 25 degrees, the width of the seal portion 18 becomes narrow and the space between the ventilation port device 1 and the outer wall 2 cannot be sufficiently sealed. On the other hand, when the angle of the guide members 35 and 35 with respect to the plate-shaped wall 14 exceeds 50 degrees, rainwater may infiltrate into the vent 3, and the guide member 35 travels along the outer surface of the seal portion 18. The rainwater that has flowed down and reached the lower end of the seal portion 18 falls as it is, and guides the rainwater along the lower surfaces of the guide members 35 and 35 to the inside of the hood member 5 as desired, and drains the plate. It becomes difficult to lead to 28, which is not preferable.

In the ventilation port device 1 according to the preferred embodiment of the present invention configured as described above, rainwater is guided as follows at the time of rainfall.

The rainwater that has poured onto the upper surface of the hood member 5 of the ventilation port device 1 flows on the upper surface of the hood member 5 and flows down to the ground, but a part of the rainwater flows down along the left and right surfaces of the hood member 5. Therefore, a part of the rainwater flows down along the outer surface of the sealing portion 18 filled with the caulking material.

Since dirt easily adheres to the surface of the caulking material, the rainwater flowing down along the outer surface of the sealing portion 18 filled with the caulking material contains dirt adhering to the outer surface of the sealing portion 18.

Further, since the seal portion 18 filled with the caulking material is in contact with the outer wall 2, the rainwater that flows down along the outer surface of the seal portion 18, leaves the outer surface of the seal portion 18, and falls downward is collected from the building. It was passed to the surface of the outer wall 2 and easily flowed on the surface of the outer wall 2, and as a result, streaky stains may be generated on the surface of the outer wall 2 of the building.

Therefore, conventionally, as a draining plate 28 that leaves the outer surface of the seal portion 18 and receives rainwater falling downward, a draining plate 28 whose width is larger than the width of the hood member 5 is provided on the lower edge portion of the hood member 5. , Rainwater that flows down along the outer surface of the seal portion 18 and leaves the outer surface of the seal portion 18 is passed to the draining plate 28 so that it does not flow on the surface of the outer wall 2 and is stained and streaked on the outer wall 2. It was prevented from causing stains on the surface.

However, when the lateral length of the ventilation port device 1 of the draining plate 28 is larger than the width of the hood member 5, not only the appearance is poor, but also the ventilation port device 1 to which the draining plate 28 is attached is carried. The left and right ends of the drainer plate 28 may be bent and damaged during the operation, and the ventilation port 28 may be prevented from being bent when the ventilation port device 1 is transported. There is a problem that extra labor and cost are required for packing the device 1.

Therefore, in the present embodiment, each of the left and right ends of the wall 26 of the draining plate forming portion 25 extends diagonally upward into the caulking material filling portion 15, and rainwater is supplied to the inside of the hood member 5 along the lower surface thereof. The guide members 35, 35 for guiding toward the direction are formed, and the rainwater flowing down along the outer surface of the seal portion 18 is configured to be guided on the draining plate 28 by the guide members 35, 35.

That is, according to the present embodiment, the rainwater that flows down along the outer surface of the seal portion 18 filled with the caulking material and reaches the lower end portion of the seal portion 18 flows along the lower surfaces of the guide members 35 and 35. It is guided to the inside of the hood member 5. As a result, even if the lateral length of the ventilation port device 1 of the draining plate 28 and the width of the hood member 5 are equal, rainwater is surely delivered to the draining plate 28, so that it travels along the outer surface of the seal portion 18. Rainwater that has flowed down and reached the lower end of the seal portion 18 is surely prevented from flowing down on the surface of the outer wall 2, flows along the surface of the seal portion 18, and rainwater containing dirt flows on the surface of the outer wall 2. It is possible to surely prevent the streak-like stains caused by flowing down the building from being generated on the surface of the outer wall 2 of the building.

Further, according to the present embodiment, since the lateral length of the ventilation port device 1 of the drainer plate 28 is substantially equal to the width of the hood member 5, the lateral length of the ventilation port device 1 of the drainer plate 28 is the hood. The appearance does not deteriorate as in the case where it is larger than the width of the member 5, and when the ventilation port device 1 provided with the draining plate 28 is transported, it is larger than the hood member 5 in the width direction of the hood member 5. However, the left and right ends of the draining plate 28 protruding outward are not bent and damaged. Further, in order to prevent the left and right ends of the draining plate 28 protruding outward from the hood member 5 from bending in the width direction of the hood member 5, extra labor and cost are required for packing the ventilation port device 1. Traditional problems can also be solved.

FIG. 5 is a schematic rear view of the ventilation port device according to another preferred embodiment of the present invention, showing a state in which a caulking material is filled in the seal portion.

As shown in FIG. 5, in the ventilation port device 1 according to the present embodiment, the hood member 5 has a substantially dome-shaped cross section.

In the present embodiment, the opening 11 formed on the surface of the hood member 5 on the outer wall 2 side has a substantially dome shape, and the hood member 5 around the opening 11 has a substantially dome-shaped plate-shaped wall 14. The caulking material filling portion 15 is formed by the plate-shaped wall 14 and the outer surface of the hood member 5 on the outer wall 2 side, and the caulking material filling portion 15 is filled with the caulking material. The seal portion 18 is formed.

Also in this embodiment, the rainwater that flows down along the outer surface of the sealing portion 18 filled with the caulking material in the caulking material filling portion 15 and reaches the lower end portion of the sealing portion 18 is hooded by the guide members 35 and 35. Since it is guided to the inside of the member 5 and surely delivered to the drain plate 28, rainwater that flows down along the outer surface of the seal portion 18 and reaches the lower end portion of the seal portion 18 flows on the surface of the outer wall 2. The streaks caused by the fact that the caulking material filling portion 15 is surely prevented from flowing down, flows along the surface of the sealing portion 18 filled with the caulking material, and rainwater containing dirt flows down on the surface of the outer wall 2. It is possible to reliably prevent the appearance of stains on the surface of the outer wall 2 of the building.

FIG. 8 is a schematic rear view of the ventilation port device shown in FIG.

As shown in FIGS. 6, 7 and 8, the cover member 55 has a substantially rectangular cross section, and a garage 58 is formed on the surface opposite to the outer wall 2 to form the outer wall of the cover member 55. An opening 59 is formed on the second side.

As shown in FIG. 8, an opening 56 is formed on the outer wall 2 side of the base member 57.

Further, as shown in FIGS. 6, 7 and 8, a seal portion forming member 60 is attached to the surface of the base member 57 on the outer wall 2 side. The seal portion forming member 60 has an L-shaped cross section, and has an adhesive portion 60a bonded to the surface of the outer wall 2 side of the base member 57 and a plate-shaped wall portion 60b substantially perpendicular to the surface of the base member 57. The caulking material filling portion 65 is formed by the plate-shaped wall portion 60b and the surface of the outer base member on the outer wall 2 side.

A drainer plate forming portion 70 is formed on the lower edge portion of the base member 57.

The drainer plate forming portion 70 is substantially perpendicular to the surface of the base member 57 and substantially parallel to the surface of the base member 57 from the top of the wall portion 76 and the wall portion 76 having substantially the same height as the plate-shaped wall portion 60b. A flat plate-shaped portion 77 extending downward and a draining plate 78 extending diagonally downward and forward (in a direction away from the outer wall 2) from the lower edge portion of the flat plate-shaped portion 77 are provided.

As shown in FIG. 8, the lateral length of the ventilation port device 51 of the draining plate 78 is set to be substantially equal to the width of the cover member 55.

The draining plate 78 guides the rainwater that has flowed down to the draining plate 78 so as to be separated from the outer wall 2. As shown in FIG. 7, both side portions 78a and 78a of the draining plate 78 are the surfaces of the draining plate 78. On the other hand, it is bent at a substantially right angle to prevent rainwater that has flowed down to the drainer plate 78 from flowing sideways, and at the same time, the strength of the drainer plate 78 is improved.

As shown in FIGS. 7 and 8, both lower ends of the plate-shaped wall portion 60b substantially perpendicular to the surface of the base member 57 of the seal portion forming member 60 are bent and diagonally upward in the caulking material filling portion 65. Guide members 63, 63 extending to are formed. In this embodiment, the guide members 63, 63 are formed so as to form an angle of 40 degrees with respect to the plate-shaped wall 60b.

FIG. 9 is a schematic rear view of a ventilation port device showing a state in which the caulking material is filled in the caulking material filling portion 65.

When the ventilation port device 1 is attached to the outer wall 2 of the building, the caulking material filling portion 65 is filled with the caulking material. As shown in FIG. 9, the caulking material is filled in the caulking material filling portion 65 at substantially the same height as the plate-shaped wall 60b formed in a substantially rectangular shape, and the cross section is substantially rectangular. The seal portion 68 is formed.

It is not always necessary that the guide members 63, 63 are formed so as to form an angle of 40 degrees with respect to the plate-shaped wall 60b, and the guide members 63, 63 are 25 with respect to the plate-shaped wall 60b. The angle may be between degrees and 50 degrees, preferably 30 degrees and 45 degrees. When the angle of the guide members 63 and 63 with respect to the plate-shaped wall 60b is less than 25 degrees, the width of the seal portion 68 becomes narrow and the space between the ventilation port device 51 and the outer wall 2 cannot be sufficiently sealed. On the other hand, when the angle of the guide members 63 and 63 with respect to the plate-shaped wall 60b exceeds 50 degrees, rainwater may enter the vent 3, and the guide member 63 travels along the outer surface of the seal portion 68. The rainwater that has flowed down and reached the lower end of the seal portion 68 falls as it is, and guides the rainwater along the lower surfaces of the guide members 63, 63 to the inside of the cover member 55 as desired, and drains the plate. It becomes difficult to lead to 78, which is not preferable.

In the ventilation port device 1 according to the preferred embodiment of the present invention configured as described above, rainwater is guided as follows at the time of rainfall.

The rainwater that has poured onto the upper surface of the cover member 55 of the ventilation port device 51 flows on the upper surface of the cover member 55 and flows down to the ground, but a part of the rainwater flows down along the left and right wall surfaces of the cover member 55. Therefore, a part of the rainwater flows down along the outer surface of the sealing portion 68 filled with the caulking material.

Since dirt easily adheres to the surface of the caulking material, the rainwater flowing down along the outer surface of the sealing portion 68 filled with the caulking material contains dirt adhering to the outer surface of the sealing portion 68.

In addition, since the seal portion 68 filled with the caulking material is in contact with the outer wall 2, the rainwater that flows down along the outer surface of the seal portion 68, leaves the outer surface of the seal portion 68, and falls downward is the building. It was passed to the surface of the outer wall 2 of the building and easily flowed on the surface of the outer wall 2, and as a result, streaky stains may be generated on the surface of the outer wall 2 of the building.

Therefore, conventionally, as a draining plate 78 that leaves the outer surface of the seal portion 68 and receives rainwater falling downward, the draining plate 78 whose lateral length of the ventilation port device 51 is larger than the width of the base member 57 is used. It is provided on the lower edge portion of the base member 57 and flows down along the outer surface of the seal portion 68 so that rainwater leaving the outer surface of the seal portion 68 is passed to the drainer plate 78 and does not flow on the surface of the outer wall 2. Therefore, it was possible to prevent the outer wall 2 from being soiled in the form of stains and streaks.

However, when the lateral length of the ventilation port device 51 of the draining plate 78 is larger than the width of the base member 57, not only the appearance is poor, but also the ventilation port device 51 to which the draining plate 78 is attached is carried. In order to prevent the left and right ends of the drainer plate 78 from bending when the drainer plate 78 is transported, the left and right ends of the drainer plate 78 may be bent and damaged. There is a problem that extra labor and cost are required for packing 51.
