Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an improvement of a gallery installed in an opening for ventilation provided in an outer wall of a room in which an air conditioner is installed, an electric room, a machine room of an elevator, or the like. It is about.

[Conventional technology]

It is necessary to prevent rainwater from being blown into the room even on a windy and rainy day in the gallery installed in the ventilation opening provided on the outer wall of the room where the air conditioner is installed, the electric room, the machine room of the elevator, etc. .

Therefore, conventionally, as shown in FIG. 9, an intermediate water return portion A is provided in the widthwise intermediate portion of each louver plate 4 (in the middle of the ventilation passage R formed between the adjacent louver plates 4 and 4). Rainwater is prevented from being blown in by devising the cross-sectional shape of the louver plate 4, such as by forming the louver plate 4 or by forming the water return portion C at the indoor end of each louver plate 4.

However, since the wind speed is high during rough weather such as a typhoon, rainwater cannot be prevented from entering with the above configuration, no matter how the cross-sectional shape of the louver plate 4 is modified.

Therefore, for example, Japanese Examined Patent Publication No. Sho 49-35781 and Shokai No. 58-1
As can be seen in Japanese Patent No. 31332, a valve body biased to an open position is provided in the ventilation passage formed between the adjacent louver plates, and the valve body becomes A waterproof gallery has been proposed which is configured to block the ventilation passage against the biasing force.

However, in these conventional examples,
Since the valve body was swingably supported by the louver frame body via the support shaft, support shafts were integrally provided at both ends of the valve body, or the support shaft was inserted through the through holes formed in the valve body. In addition, it is necessary to provide the bearing portion on the louver frame body,
There was a problem that the structure became complicated.

[Problems to be solved by the invention]

The present invention has been made in view of the above conventional drawbacks, in which the valve body is made of an elastic material such as rubber or soft synthetic resin, and the ridge portion formed on a part of the valve body is formed on the louver plate. By elastically fitting in the dovetail groove (groove of the back) and mounting, the valve body mounting screw and bearing are not required, which simplifies the structure and facilitates the replacement work of the valve body. However, it is intended to prevent the ridges from accidentally coming out of the dovetail groove when the valve body swings in the closing direction.

[Means for solving problems]

The technical means taken by the present invention to achieve the above object are as follows. That is, a feature of the present invention is that a valve body biased to an open position is provided in an air passage formed between adjacent louver plates, and the valve body is attached to the valve body when a predetermined wind speed or more is reached. In a waterproof gallery configured to block the ventilation passage against a force, a dovetail groove along the longitudinal direction of the louver plate is formed on the rear end side of the louver plate in the ventilation direction, while the valve element is elastic. A main plate portion made of a material and having a width capable of blocking the ventilation passage, a base portion narrower than the main plate portion folded back from the rear end edge of the main plate portion, and a surface facing the main plate portion of the base portion. And a ridge protruding from the opposite surface, the ridge is elastically fitted in the dovetail groove, and the main plate is configured to swing around a position behind the base. Especially.

[Action]

According to the above configuration, the valve body is made of an elastic material such as rubber or soft synthetic resin, and the ridge portion formed on the base portion of the valve body is elastically fitted into the dovetail groove (groove of widening) formed on the louver plate. Since it is configured so that the valve disc mounting screw and the bearing portion are not required, the structure can be simplified and the valve disc replacement work can be facilitated. Since it swings about the position, when the valve body swings in the closing direction, no force acts on the ridge portion of the base portion in the direction of slipping out from the dovetail groove.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. First
Figures 3 to 3 show a vertical waterproof gallery. Reference numeral 1 is a louver frame body including left and right vertical frames 2,2 and upper and lower horizontal frames 3,3. A plurality of louver plates 4 ... They are arranged at intervals. Both the louver body 1 and the louver plate 4 are extruded aluminum products, but may be made of other materials such as stainless steel.

As shown in the transverse sectional shape in FIG. 1, the louver plates 4 ... Reinforcement plate portion 6 at the outdoor side end of the first curved plate portion 5 which is smoothly curved in the width direction (that is, the ventilation direction). To
An intermediate plate portion 7 forming an intermediate water return portion A at the end portion on the indoor side
And a second curved plate portion 8 that is smoothly curved in the same direction as the first curved plate portion 5 are continuously connected to the intermediate plate portion 7. The end portion is slightly protruded to the outside of the intermediate plate portion 7 to form a second intermediate water return portion B by the protruding portion, and the tip is provided at the indoor end portion of the second bending plate portion 8. A plurality of vertical strips for connecting the plate portion 10 having the folded plate portion 9 in series to form a water return portion C, and capturing and draining rainwater to the first curved plate portion 5 and the second curved plate portion 8 respectively. Groove a
Is formed. R is an air passage formed between the adjacent louver plates 4, 4. The surface b of the connecting portion between the reinforcing plate portion 6 and the first bending plate portion 5 is formed into a curved surface so that water droplets are less likely to splash toward the center of the ventilation passage R.

In the ventilation passage R, a position closer to the room than the first curved plate portion 5 (in this embodiment, a portion in the vicinity of the connecting portion between the second curved plate portion 8 and the plate portion 10) is used as a fulcrum to move forward and backward. A valve body 11 made of an elastic material such as rubber or soft synthetic resin, which is swingable and openable and urged in an open posture by an elastic restoring force, is attached to an outer edge portion 11 of the valve body 11.
a is provided so as to slightly project from the tip of the intermediate plate portion 7 toward the center of the ventilation passage R. In a normal state, when the valve body 11 maintains the open posture and the wind speed in the ventilation passage R becomes higher than a predetermined value, the valve body 11 swings to a position where it hits the plate portion 10, and the ventilation passage R Is configured to close.

According to the above configuration, in the normal state, the ventilation passage R
Since the wind velocity in the air is low, the wind flows along the shape of the ventilation passage R, but in a strong wind, the wind tends to flow linearly, and the outer edge portion 11a of the valve body 11 protruding from the intermediate plate portion 7 guides the wind. Since it is strongly received, the valve body 11 swings rearward against its elastic restoring force and closes the ventilation passage R, and when the wind weakens, the valve body 11 returns to the original open posture.

That is, when the wind speed increases, the valve body 11 is pressed against the plate portion 10 by the wind pressure, and the amount of air leakage decreases. As a result, the valve body 11
Since the space on the front side (ventilation path R) and the outdoor space approach an equal pressure and air movement is reduced, rainwater is reinforced by the reinforcing plate portion 6
Also, the rainwater flows down along the first curved plate portion 5 and does not move further into the ventilation passage R, so that rainwater is prevented from entering the indoor side.

In this way, the valve body 11 closes the ventilation passage R every time the wind speed becomes higher than a predetermined value, so that it is possible to reliably prevent rainwater from being blown in.

Further, when the ventilation passage R is closed, the valve body 11 is supported not only by the root portion of the plate portion 10 but also by the folded portion 9 at the tip of the plate portion 10, so that a strong wind such as a typhoon (for example,
It can withstand wind pressure even at 50m / s).

The wind speed at which the valve body 11 is closed can be arbitrarily set by selecting the material and thickness of the valve body 11. For example, since the wind speed in the ventilation passage R during air conditioning operation is usually 2 to 5 m / s,
It is desirable to set the valve body 11 so that it does not move at this wind speed, and to close when the wind speed is 8 to 12 m / s or more. Also, depending on the material of the valve body 11, when it is made of rubber, if the wall thickness of the valve body 11 is too thin, the valve body 11 is easily deformed and the open posture cannot be reliably held. It is desirable to have a thickness of about 1.5 mm because it is not familiar well and gaps are likely to occur, whistling phenomenon occurs and it is easy to bend. Although various means can be envisaged for attaching the valve body 11 to the louver plate 4, in the present invention, as shown in FIG. 1, one side of the louver plate 4 is provided with a dovetail groove (rearward expansion) on the rear end side in the ventilation direction. 4a, the base 11b of the valve body 11 is provided with a raised portion 11c having a substantially trapezoidal cross section and a narrowed root portion, as shown in FIGS. Therefore, the raised portion 11c can be pushed in and elastically fitted into the dovetail groove 4a. This is intended to simplify the work of replacing the valve body 11 by omitting the valve body mounting screw and the like.

Particularly, in the present invention, as shown in FIGS.
The base 11b has a shape in which the base 11b is folded back from the rear end edge of the main plate 11d so that the main plate 11d swings around a position rearward of the base 11b. This is because even if the simple attaching means as described above is adopted, when the main plate portion 11d swings in the closing direction, the force in the direction of coming out of the dovetail groove 4a is applied to the ridge portion 11c of the base portion 11d. Special consideration was given so that it would not work.

6 to 8 show another embodiment of the present invention. This embodiment is characterized in that the present invention is applied to a horizontal waterproof louver in which louver plates 4 are arranged at predetermined intervals in the vertical direction between the left and right vertical frames 2, 2 of the louver frame body 1. is there. More specifically, the illustrated plate 4 includes a hanging plate portion 12,
A first swash plate portion 13 that is continuously provided from the upper end and is inclined so as to be higher toward the indoor side, and a second swash plate portion 14 that is provided at the upper end and is steeper than the first swash plate portion 13. A third swash plate portion 15 that is connected to the upper end of the second swash plate portion 14 and the first swash plate portion 13 is more gently inclined, and a rising plate portion 16 that rises from the upper end There is. Further, the lower end edge of the third swash plate portion 15 is made to project slightly outward from the upper end of the second swash plate portion 14, and an intermediate water return portion A is formed below the protruding portion. A folding plate portion 17 is provided on the upper end of the rising plate portion 16 to form a water folding portion C. In the ventilation passage R formed between the adjacent louver plates 4 and 4, a position on the lower surface side of each louver plate 4 and on the indoor side of the first swash plate portion 13 (in this embodiment, the third swash plate). The valve body 11 is made of an elastic material such as rubber or soft synthetic resin, which is swingable up and down about a fulcrum (a lower surface of the plate portion 15) and is biased to an open position by an elastic restoring force.
The outer edge portion 11a of 11 is provided so as to project downward from the corner portion of the first swash plate portion 13 and the second swash plate portion 14. 18 in the figure
Is a gutter frame, and the rainwater flowing down along the building outer wall W is guided to the gutter frame 18 by the drainer 3a formed on the upper horizontal frame 3, and the vertical groove portions 2a, 2a formed on the vertical frames 2, 2 are guided. After that, it is drained. The other structure is the same as that of the previous embodiment.

According to this embodiment, as in each of the above-described embodiments, in addition to the effect that the valve body 11 closes the ventilation passage R every time the wind speed becomes higher than a predetermined value to prevent the rainwater from being blown in, The effect of is obtained.

That is, the valve body 11 closes only in a strong wind, and most of the time,
Although the valve body 11 is in the open position, the valve body 11 is attached to the ceiling surface (lower surface) of the glass plate 4, so the valve body 11 is in the open position.
Dust is not easily attached to the. In addition, the valve body 11 is each glass plate 4
It is attached so as to swing and open around a position on the lower surface side of the first swash plate portion 13 that is closer to the indoor side than the first swash plate portion 13, and the valve body outer edge portion 11a is provided with the first swash plate portion 13 and the second swash plate portion 14. Since it only slightly protrudes from the corners of and, it is not exposed to direct sunlight.
Therefore, adhesion of dust and deterioration of the valve body 11 due to direct sunlight are suppressed, and desired performance can be maintained for a long period of time.

[Effect of device]

Since the present invention is configured as described above, it is possible to simplify the structure and facilitate the replacement work of the valve body, and yet, since the main plate part swings about a position rearward of the base part, When the body swings in the closing direction, no force acts on the ridge of the base in the direction to get out of the dovetail, and a simple attachment means is adopted that elastically fits the ridge into the dovetail. Nevertheless, the ridges do not unexpectedly come out of the dovetail
