Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a gallery that is attached to a wall surface, a ventilation pipe, or the like for ventilation.

(Prior Art) Conventionally, many devices have been proposed for performing ventilation, but among them, a device of the same type as a gallery is proposed in Japanese Utility Model Publication No. 61-36112.

According to the above-mentioned proposal, "a guarding door 6 is provided between the outdoor hood 1 and the opening 5 of the communicating cylinder 2 on the indoor side, and the opening 5 of the communicating cylinder 2 is covered by the upper portion 3 of the hood. In the ventilator, the diameter of the hood 1 is formed to be larger than the diameter of the ventilation cylinder 2 on the indoor side, and the ventilation cylinder 2 is eccentrically mounted above the hood. The upper part 3 is bulged outward in a hemispherical shape, the lower part is cut out in an arc shape to form an air intake part 4, and the drain hole 10 is provided at the lower end part of the through cylinder 2. It is an attachment aerator. "

(Problems to be solved by the invention) According to the above-mentioned proposal, "In the conventional ventilator for installation, the air intake and the vent to the room are concentric, and the grill with a hood is attached to the air intake. However, in the case of strong winds, there was a drawback that the rain and snow sprayed diagonally would penetrate from the lower part of the vent hole. "Therefore, it is described as a proposal to eliminate this drawback.

However, in the case of the one shown in the figure, when it is blown diagonally from below (the wind condition is high when the installation location is high), the wind accompanied by rain and snow can easily enter the inside, This does not mean that the drawbacks of the conventional attachment ventilators have been eliminated.

(Means for Solving the Problem) The present invention has been made by paying attention to such a conventional problem, and when wind and rain invade, it collides with a barrier in advance to weaken the wind force to prevent rain. The above problems are solved by providing a gallery of a structure in which rain can be further separated by separating winds as much as possible and then changing the direction of the wind to prevent rain from penetrating inside. Is intended.

The present invention relates to an outer cylinder having a body portion having a required length, which is provided with a collar portion having a downward water drop at one end, and either a locking collar or an extension portion at the other end, and the body portion. A plurality of ventilation holes are formed in the inner body portion, which is fitted and fixed at a required gap and whose one end is shielded, the other end has an L-shaped inner flange portion that is in contact with the body portion, and a lower portion below the inner flange portion. It is a gallery characterized in that it is composed of an inner cylinder provided with a drain hole and a drain hole respectively.

(Operation) In the gallery, the wind accompanied by rain that has entered through the gap between the outer cylinder and the inner cylinder collides with the inner collar part and weakens the wind force to partly separate the contained rainwater. Although it descends along the collar part and is discharged to the outside through water handling, the collided wind is redirected and enters the inside through the ventilation hole,
At this time, the wind force is further weakened and most of the contained rain is further separated, and the rainwater descends along the inside of the inner cylinder and is drained to the outside through the drain hole-body-separation. Even if it is accompanied by wind, it is passed inside with almost all rainwater removed.

Also, the gallery has a simple structure, which makes it easy to manufacture.
It can be manufactured at low cost.

(Embodiment) The present invention will be described in detail below based on an embodiment shown in FIGS. Reference numeral 1 denotes an outer cylinder having a body portion 2 having a predetermined length, and at one end 3 thereof, a front end portion is bent outward at a predetermined width by 90 °, and a front end portion is further bent in an arc shape to form a collar portion 4 And a water separator 6 which is formed by pressing a part of the collar portion 4 below the collar portion 4 and discharges the internal water to the outside so as not to be transmitted to the mounting wall 5, and at the other end 7, Locking with the tip bent inward at 90 ° with a predetermined width (the upper part of the circumference of the other end 7 is bent into a ring 8'and the lower part is bent into a chordal circle 8 ") The collar 8 is provided, and the body 2 near the other end 7 is provided with three fixed pawls 9 obtained by cutting out and bending a part of the body wall outward at equal intervals.

Reference numeral 10 denotes an inner cylinder which is coaxially fitted in and fixed to the body portion 2 with a required gap, and is parallel to the lower portion of the inner body portion 12 which is shielded at one end 11 and is oblique and has a required distance. A large number of rectangular ventilation holes 13 are formed on the other end, and the other end 14 has a tip portion with a predetermined width of 90 mm.
The outer flange portion 15 and the inner collar portion 15 which is bent parallel to the inner body portion 12 at 90 °, in other words, is bent into an L shape and is brought into contact with the body portion 2, and Drainage holes 16 are provided below the collar portion 15, respectively.

In the gallery 17, the inner flange portion 15 of the inner cylinder 10 is inserted into the body portion 2 of the outer cylinder 1 from one end side, the inner flange portion 15 is brought into contact with the locking flange 8, and the inner flange portion is attached to the body portion 2. 15 is fixed by spot welding and assembled. At that time, the widthwise centers of the water separating member 6 and the water draining hole 16 must be on the same center line.

The gallery 17 is used by inserting and inserting the body portion 2 with the collar portion 4 on the outside in a ventilation pipe or the like which is directly attached to or attached to a ventilation port provided in the mounting wall 5.

When the wind accompanied by rain enters the gallery 17 from the gap between the body 2 of the outer cylinder 1 and the inner body 12 of the inner cylinder 10, the gallery 17 collides with the inner collar 15 first, so that the wind force is weakened. Part of the contained rain is separated, and the separated rainwater descends along the inner collar portion 15 and the inner trunk portion 12 and is discharged to the outside via the water separator 6. (At this time, the rainwater is separated by the water separator 6. It is discharged without passing through the mounting wall 5),
Subsequently, the collided wind is redirected and enters the inside through the vent hole 13 of the inner trunk portion 12, but the wind force is further weakened at this time, and most of the contained rain is further separated and separated. Since the rainwater descends along the inside of the inner trunk 12 and is discharged to the outside through the drain hole 16-trunk 2-the water separator 6, the rainwater is almost removed even if the wind is accompanied by considerable rain. Pass it inside.

Further, the gallery 17 has a simple structure and thus can be easily manufactured, and can be manufactured at low cost.

In the above-described embodiment, the water separator 6 provided below the collar portion 4 is formed by pressing a part of the collar portion 4. However, the water that has passed below the body portion 2 is attached to the mounting wall. If it can be discharged to the outside without passing through 5, it is not restricted to this structure.

Further, the locking wall 8 of the outer cylinder 1 is provided for fixing the position of the inner cylinder 10 and for preventing rainwater descending to the lower part from flowing out to the indoor side by the locking wall 8 having the chordal shape 8 ″. If the lower part of the inner flange portion 15 of the inner cylinder 10 is formed in a U-shape, it is not always necessary to provide it.

Further, the locking wall 8 is provided on the other end 7 of the body portion 2 of the outer cylinder 1. However, by stopping this and providing an extended portion 18 (illustrated by a chain line in FIG. 3) which is simply extended, It is possible to install a soundproof device having a soundproof wall inside, a fireproof device having a function of closing a passage during a fire, or the like.

Further, in order to fix the gallery 17 to the ventilation hole or the like, a part of the body wall is cut out in the body portion 2 of the outer cylinder 1 and the fixing pawl 9 is provided.
Instead of the fixed pawl 9, a plate-shaped fixed pawl made of another elastic material may be fixedly provided.

Further, in the inner barrel portion 12 of the inner cylinder 10, a rectangular ventilation hole 13 is provided which is obliquely formed and is formed in parallel in parallel at a plurality of appropriate intervals. In short, rainwater is passed through by allowing wind to pass therethrough with a minimum resistance. As long as it is not carried in too much and the necessary mechanical strength of the inner barrel portion 12 is maintained, it is not restricted by the shape and the drilling method shown.

(Operation) Since the present invention has the above configuration, it has the following effects.

(1) Since rainwater can be reliably separated even if wind accompanied by rain enters, its rainproof function is extremely excellent and damage to buildings due to rainwater can be prevented.

(2) Since it can be provided to customers at low cost despite having excellent functions, it is possible to meet the demands of customers and expand sales.

(3) Since the structure is simple, there are few places where failures occur,
Easy maintenance and long service life.
