Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eaves-ventilation cylinder.

Conventional technology Conventionally, in general houses, in order to ventilate from the eaves,
A relatively flat and horizontally long rectangular cylinder is used as a ventilation cylinder to be fitted and fixed to the wall of the eaves.

However, if the ventilation cylinder is a quadrangular cylinder, rainwater will rise inward with the wind along the roof of the eaves, passing through the cylinder and invading the house. In order to block the rainwater, a plurality of baffles rising up and down alternately may be provided in the cylinder to form an air passage in which the air flows in a meandering manner. However,
If a plurality of baffle plates are attached as separate members to the inside of the cylinder, it takes time to assemble and the cost becomes high.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention provides a eaves-ventilation cylinder designed so that a baffle plate that allows air to flow in a meandering shape is bent from a sheet metal material together with a relatively flat and oblong rectangular tube body. With the goal.

Means for Solving the Problems In the eaves-ventilation cylinder according to the present invention, there is provided a rectangular tube-shaped cylinder body composed of a relatively flat and horizontally long top plate, a bottom plate, and left and right side plates that are fixed by being inserted into a wall part of the eaves. It is made of two sheet metal materials that are cut as the top plate side and the bottom plate side. On the top plate side, the front end side of the top plate is bent downward at a right angle, and the ventilation hole between the lower end and the bottom plate surface is formed in the cylinder body. A front blocking plate is formed on the front side of the top plate, and the front end part of the top plate and the rear end part of the top plate that are continuous from the front blocking plate are bent into the inside of the cylinder main body and moved downward in the direction perpendicular to the top plate surface. A baffle to stand up is provided, and further,
At the bottom plate part, the front and rear ends of the bottom plate are bent inward of the cylinder body to provide baffle plates that stand upright in the direction perpendicular to the bottom plate surface. It is configured by forming a whole sheet metal material including a ventilation path that allows the ventilation to flow in a meandering shape.

Function In this ventilation cylinder, each end of the top plate and bottom plate that form the cylinder body is bent inside the cylinder body to provide each baffle plate that blocks rainwater, and the front blocking plate also folds the front end side of the top plate. By bending, the two sheet metal materials cut into the top plate side and the bottom plate side as a whole are formed, so that the sheet metal material can be cut and formed easily and the entire bending can be easily formed.

Embodiments The following will be described with reference to the accompanying drawings.

The eaves-ventilation cylinder is bent and formed using a sheet metal material. As shown in FIG. 1, the ventilation cylinder is composed of a relatively flat and horizontally long rectangular tube main body 10 which is inserted and fixed to the wall portion of the eaves, and the cylinder main body 10 is cut into a predetermined shape as described later. It is formed by using two sheet metal materials.

On the front side of the cylinder body 10, a front blocking plate 13 is provided which forms a ventilation port W ₁ between the lower end and the plate surface of the bottom plate 12 by bending the front side of the top plate 11 downward in the perpendicular direction. ing.
Further, by bending the front end portion of the top plate 11 continuing from the front shielding plate 13 and the rear end portion of the top plate 11 into the inside of the cylinder body 10, the baffle plates 14 and 1 that stand upright downward from the top plate surface.
Five are provided. Among the baffles 14 and 15, the one by the front end portion 14 is overlapped with the inside of the front blocking plate 13 and bent at a right angle along the inner surface of the top plate 11, and further downward from the predetermined position on the inner surface of the top plate 11 in the right angle direction. Top plate 11 by folding into
It is formed of a continuous sheet metal material. In addition, the cylinder body 10
15 by the rear end of the top plate located inside
It is formed by overlapping and bending along the inner surface of the top plate 11 from the rear end side, and bending downward from a predetermined position on the inner surface of the top plate 11 in the direction perpendicular to the surface. Baffles 16 and 17 that have the same bent shape as the top end of the top plate 11 and the front and rear ends of the bottom plate 12 are bent into the inside of the cylinder body 10 and rise vertically upward from the side surface of the bottom plate 12. It is provided. Each of these baffles 1
4,15,16,17 are provided with a rising dimension l ₂ which is slightly smaller than the interval l ₁ between the top plate 11 and the bottom plate 12 and are arranged at predetermined intervals so as to be alternately arranged vertically.

Further, as shown in FIG. 2, on the front surface side of the cylinder main body 10, the above-mentioned vent hole W ₁ is defined from the left and right contact plates 18, 19 and the lower contact plate 20 including the front blocking plate 13. A quadrilateral flange portion is formed. Each of these backing plates 18, 19, 20 is used for attaching the tube body 10 by applying and fixing it to the outer wall of the eaves. In addition, the cylinder body 10 located on the indoor side
Left and right side plates 21, 22 are formed at the rear end of the cylinder body 10 so as to be continuous from the top plate side. The side plates 21 and 22 are provided with indoor side contact plates 23 and 24, respectively, by bending the rear ends thereof outward as shown in FIG.

In the eaves-ventilation cylinder thus configured, the wind hitting the front shielding plate 13 is blocked so as not to flow into the inside of the cylinder body 10, but can be circulated into the inside of the cylinder body 10 from the ventilation port W ₁ . When rainwater enters with the outside air, the outside air accompanied by the rainwater hits the baffle plate 16 rising from the bottom plate 12 and flows upward, and this time hits the baffle plate 14 rising from the top plate 11 and flows downward so that it flows downward. Go through ₂ meandering.
All the rainwater is drained on the way, so that the baffle plate 17 can be blocked from moving indoors.

In this eaves ventilating cylinder, the top plate side cut into the shape shown in FIG. 4 and the bottom plate side cut into the shape shown in FIG. 5 are each bent into a predetermined shape, and both are combined. Can be formed. When bending it, bend it inward along the fold line indicated by the broken line and bend it outward along the fold line indicated by the alternate long and short dash line.
By fixing with rivet pins 29, 30 inserted into 6, 27, 28, it is possible to assemble and mold into a predetermined three-dimensional shape shown in FIG.

Effect of the Invention As described above, according to the eaves ventilation tube according to the present invention, it is possible to easily ventilate the indoor air and efficiently cut off the rain water from the inside by using two sheet metal materials. Can be assembled and molded.
