Description

  TECHNICAL FIELD The present invention relates to a housing rainproof panel that can be suitably used as a joinery that is installed and used at a desired location such as a house window or a veranda, or as a component of a joinery.

  There is a case where it rains while the window is opened to ventilate indoors, and the rain blows into the room indoors. In order to prevent such a problem, it is conceivable to use a window door (including a door such as a shutter) having rain resistance while having excellent air permeability. With such a door, there is no need to keep the door open for the purpose of ventilating indoors, and it is possible to ventilate indoors with the door closed. This is because it is possible to prevent rain from blowing indoors.

  Conventionally, there exists what was described in patent document 1 as a shutter which has air permeability. However, since the shutter described in the document is merely a structure in which a plurality of ventilation holes are simply provided through, the rainproof performance is low. More specifically, in the shutter described in Patent Document 1, if the size of each ventilation hole is made relatively large in order to improve the air permeability, rain easily passes through each ventilation hole and proceeds indoors. It becomes. In this case, the rainproof performance is considerably lowered, and the original role as a shutter cannot be sufficiently fulfilled.

  In a house with a veranda, an appropriate shielding member is installed on the veranda for the purpose of preventing rain from blowing into the veranda or preventing the inside of the veranda from being easily seen from the outside. There is a case. Conventionally, as a shielding member used for such an application, a material having both excellent rainproof properties and air permeability has not been proposed. Residents may want to prevent outside air from flowing into the veranda while ensuring that sufficient outside air is taken into the veranda, but in the past, responding to such requests accurately. Was difficult.

JP 2007-177417 A

  The present invention has been conceived under the circumstances as described above, and provides a rainproof panel for a house capable of improving both rainproofness and air permeability. Is the issue.

  In order to solve the above problems, the present invention takes the following technical means.

  The rainproof panel for a house provided by the present invention is installed in a standing posture at a desired location of the house, and is used for preventing rain from entering the indoor side from the installed location. An outer panel having a plurality of first ventilation holes, and an inner panel having a plurality of second ventilation holes facing the outer panel with a space therebetween, The plurality of first and second ventilation holes are provided so as to be displaced so as not to face each other in the facing direction of the outer and inner panels.

The rainproof panel for a house having such a configuration is used, for example, as a building fixture such as a door for a window or a rainproof shielding member for a veranda, or as a component thereof, and the following effects are obtained. .
First, since the first and second ventilation holes are provided in the outer and inner panels, the entire rainproof panel for a house has air permeability in its thickness direction. Therefore, when the rainproof panel for houses of the present invention is used as a shutter, for example, indoor ventilation can be performed with the shutter closed.
On the other hand, the first ventilation hole provided in the outer panel and the second ventilation hole provided in the inner panel are displaced so as not to face each other. Even if it passes through the ventilation hole, it is appropriately prevented or suppressed that this rain passes through the second ventilation hole as it is. Such an action can be appropriately obtained even when the sizes of the first and second ventilation holes are relatively large.
Therefore, according to the present invention, even when the opening areas of the first and second ventilation holes are relatively large and the ventilation performance of the rainproof panel for houses is enhanced, excellent rainproof performance is obtained. It is possible.

  In the present invention, preferably, the whole or a part of the inner panel is corrugated, and includes a plurality of back side convex portions having inner surfaces that are recessed in a direction away from the outer panel, and the outer panel. A plurality of front side convex portions having inner surfaces protruding in the approaching direction, and the inner surfaces of the plurality of back side convex portions face the plurality of first ventilation holes, and The plurality of second ventilation holes are provided in the front convex portion.

  According to such a configuration, the rain that has passed through the plurality of first ventilation holes hits the inner surface of the rear-side convex portion of the inner panel, but this inner surface is recessed in a direction away from the outer panel. The rain hitting this inner surface tends to flow down along the inner surface as it is. Since the plurality of second ventilation holes are provided in the front side convex portion of the inner panel, the rain hitting the rear side convex portion travels along the inner surface of the inner panel and each second ventilation hole is provided. There is almost no risk of entering the hole. Therefore, it is more preferable in increasing the opening area of the first and second ventilation holes to improve the air permeability and the rainproof performance.

  In the present invention, preferably, the plurality of first and second ventilation holes are formed in a long hole shape extending in the vertical height direction and are arranged at intervals in the horizontal direction.

  According to such a configuration, for example, the outer surface of the outer panel (front surface) and the inner surface of the inner panel (front surface) are compared with the case where the first and second ventilation holes are formed in a horizontally long shape and arranged in the vertical direction. Rainwater that adheres to the water and flows downward is less likely to enter the first and second ventilation holes, and it is possible to reduce the possibility that rain will pass through the rainproof panel for a house.

  In the present invention, it is preferable to further include a frame body that surrounds outer peripheries of the outer and inner panels and supports the outer and inner panels, and includes a lower part of the frame part, a lower part of the outer panel, or the inner panel. A drainage hole for discharging the rainwater to the outside when rainwater enters a gap formed between the outer panel and the inner panel is provided in the lower portion of the plurality of second panels. One of the first and second ventilation holes is configured such that the lower end portion thereof is substantially flush with the upper surface of the lower portion of the frame portion and also serves as the rainwater drainage hole.

  According to such a configuration, rainwater can be prevented from unreasonably collecting in a gap formed between the outer and inner panels.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  A rainproof panel P1 for a house shown in FIG. 1 is configured as a shutter installed on the outside of a pair of ordinary doors 8 configured as sliding doors among windows 9 in a house or a door similar to a shutter. As clearly shown in FIG. 2, this residential rainproof panel P <b> 1 includes an outer panel 1, an inner panel 2, and a frame 3 (when the residential rainproof panel P <b> 1 is attached to the window 9). In addition, the panel disposed on the outdoor side is the outer panel 1, and the panel disposed on the indoor side is the inner panel 2. The outer and inner panels 1 and 2 are provided with a plurality of first and second ventilation holes 10 and 20.

  The outer panel 1 is made of, for example, a resin such as polycarbonate, and its basic form is a flat plate having a rectangular shape in front view. The outer panel 1 is colorless or colored and transparent that can transmit sunlight. The plurality of first ventilation holes 10 are provided so as to penetrate in the thickness direction of the outer panel 1 and have a vertically long rectangular shape having a length L1 and a width W1 extending in the vertical height direction, and are horizontally horizontal. They are lined up at regular intervals in the direction. In FIG. 2B, although the plurality of first ventilation holes 10 are provided in the upper, middle, and lower three stages in the height direction of the outer panel 1, the present invention is not limited to this. For example, each of the first ventilation holes 10 may have a longer dimension in the vertical direction, and may extend continuously from the vicinity of the upper portion of the outer panel 1 to the vicinity of the lower portion thereof. On the other hand, each first vent hole 10 can be formed with a shorter dimension than that shown in FIG.

  The inner panel 2 has the same shape and size as viewed from the front, and the material of the inner panel 2 is the same as that of the outer panel 1 and is colorless or colored and transparent. However, as shown in FIG. 2A, the inner panel 2 has a corrugated plate shape, and the back-side convex portions 21a and the front-side convex portions 21b are alternately arranged in the horizontal direction. It is the structure connected by. Each of the rear-side convex portion 21a and the front-side convex portion 21b has an arc shape in a plan sectional view, and extends uniformly in the vertical height direction. The inner surface of the rear side convex portion 21 a is recessed in a direction away from the outer panel 1, and the inner surface of the front side convex portion 21 b protrudes in a direction approaching the outer panel 1. The second ventilation hole 20 is provided in the front-side convex portion 21b and is not provided in the back-side convex portion 21a. The second ventilation hole 20 has a rectangular shape extending in the vertical height direction in the same manner as each first ventilation hole 20, and the vertical length L2 and width W2 are, for example, the first ventilation hole. 10 length L1 and width W1 are substantially the same.

  The inner panel 2 faces the outer panel 1 and is provided behind the outer panel 1 (on the upper side in FIG. 2A) so as to form a gap 40 with the outer panel 1. However, the first and second ventilation holes 10 and 20 are arranged so as to be displaced so as not to face each other. More specifically, the inner surface of the rear-side convex portion 21 a of the inner panel 2 faces behind the first ventilation hole 10. The second ventilation hole 20 is disposed so as to face a portion of the outer panel 1 where the first ventilation hole 10 is not formed (a region between the first ventilation holes 10). .

  The frame 3 is for fixing and supporting the outer and inner panels 1 and 2 so as not to move relatively, and is made of a relatively light metal such as resin or aluminum. The frame 3 has a rectangular frame shape surrounding the outer peripheral edges of the outer and inner panels 1 and 2. Preferably, as shown in FIG. 3, rail grooves 32 that fit into rails 91 provided in the frame portion 90 of the window 9 are provided in the upper portion 30 and the lower portion 31 of the frame body 3. Thereby, the rainproof panel P1 for a house is attached to the window 9 so as to be slidable along the rail 91, and can be set to either the open state or the closed state of the window 9. In the configuration shown in FIG. 3, the pair of doors 8 located on the inner side (indoor 7 side) than the residential rainproof panel P <b> 1 is configured as a sliding door, for example. Moreover, although illustration illustration is abbreviate | omitted, of course, a normal shutter may be further installed outside the rainproof panel P1 for houses.

  A drain hole 41 is provided in the lower part of the outer panel 1. The drain hole 41 is a part for discharging rainwater that has entered the gap 40 between the outer and inner panels 1, 2 from the first ventilation hole 10 to the outside of the gap 40. In the present embodiment, as shown in FIG. 2 (b), the upper surface 31a of the lower portion 31 of the frame 3 is inclined so that its height decreases as it approaches the drainage hole 41, and flows down onto the upper surface 31a. The rainwater flows smoothly toward the drain hole 41.

  Next, the operation of the above-described residential rainproof panel P1 will be described.

  First, the residential rainproof panel P1 is installed and used in the window 9 in the state shown in FIG. As shown in FIGS. 2 (a) and 3 (b), the outer and inner panels 1, 2 are provided with a plurality of first and second ventilation holes 10, 20, so that they are for residential use. The rainproof panel P1 as a whole has air permeability in its thickness direction. Therefore, the indoor 7 can be ventilated even when the rainproof panel P1 for houses is kept closed. Moreover, since the outer side and inner side panels 1 and 2 are transparent, it is possible to carry out daylighting with the window 9 closed by the residential rainproof panel P1 so that the indoor 7 does not become dark.

  On the other hand, since the first and second ventilation holes 10 and 20 are displaced so as not to face each other, rain passes through the first ventilation hole 10 as shown in FIG. Even if it does, it does not pass the 2nd hole 20 for ventilation easily, and approach of rain to an indoor is prevented appropriately with the rainproof panel P1 for houses. In particular, in this embodiment, as shown by an arrow N1 in FIG. 2A, when rain passes through the first ventilation hole 10, the rain hits the inner surface of the back-side convex portion 21a of the inner panel 2. . Since this inner surface has a concave groove shape, the rainwater then flows downward along the inner surface of the back-side convex portion 21a. Since the second ventilation hole 20 is provided in the front-side convex portion 21b, the rainwater described above is less likely to enter the second ventilation hole 20. In addition, as shown in FIG. 3A, when rain hits the rainproof panel P1 for a house, since the rain usually proceeds obliquely downward, the rain that has passed through the first ventilation hole 10 It proceeds diagonally downward until it hits the inner surface of the panel 2. On the other hand, since the second ventilation hole 20 is displaced in the horizontal direction with respect to the first ventilation hole 10, it passes through the first ventilation hole 10 and proceeds obliquely downward. It is even more difficult for rain to proceed toward the second ventilation hole 20.

  As described above, according to the rainproof panel P1 for a house of the present embodiment, the first and second ventilation holes 10, 20 are formed in a relatively large size to improve the air permeability. However, it is possible to appropriately prevent rainwater from improperly permeating the rainproof panel P1 for a house and entering the indoor 7 and obtain excellent rainproof performance. For this reason, even if the door 8 is left open to ventilate the indoor 7, if the window 9 is closed using the residential rainproof panel P <b> 1, even if it rains, the rain will fall in the indoor 7. Insufflation is appropriately prevented.

  4 to 8 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the rainproof panel P2 for houses shown in FIG. 4, in addition to the inner panel 2, the outer panel 1 is also corrugated. More specifically, the outer panel 1 has a corrugated plate shape having a plurality of back side and front side convex portions 11a and 11b having the same form as the back side and front side convex portions 21a and 21b of the inner panel 2. is there. The back side convex portions 21a and 11a and the front side convex portions 21b and 11b face each other. The plurality of first ventilation holes 10 are provided in the rear-side convex portion 11 a and are also provided so as not to face the second ventilation holes 20.

  According to the present embodiment, since the first ventilation hole 10 is configured to open close to the rear-side convex portion 21a of the inner panel 2, when rain passes through the first ventilation hole 10, Further, it is further ensured that this rain hits the inner surface of the back side convex portion 21a, and it is more appropriate that the rain proceeds toward the second ventilation hole 20 provided in the front side convex portion 21b. Is prevented. Further, since the width of the gap 40 can be made substantially uniform in each place and a narrow region can be prevented from being partially generated, the air permeability utilizing the first and second ventilation holes 10 and 20 is further improved. It is possible to improve. As understood from the present embodiment, in the present invention, in addition to the inner panel 2, the whole or a part of the outer panel 1 can be corrugated.

  In the rainproof panel P3 for a house shown in FIG. 5, both the outer and inner panels 1 and 2 are flat. However, the plurality of first and second ventilation holes 10 and 20 are displaced in the horizontal direction and are configured not to face each other.

  Also according to this embodiment, since the first and second ventilation holes 10 and 20 do not face each other, rainproof performance can be obtained. As understood from the present embodiment, the inner panel 2 does not necessarily have a corrugated plate shape, and may be a flat plate shape. However, in order to further improve the rainproof performance, as in the embodiment shown in FIGS. 1 to 3, at least the inner panel 2 (outside the inner panel 2, the first ventilation) of the outer and inner panels 1 and 2. It is preferable that the portion facing the hole 10 and the portion where the second ventilation hole 20 is provided) be corrugated, and the second ventilation hole 20 be provided in the front-side convex portion 21b.

  In the embodiment shown in FIG. 6A, a drainage hole 41 is provided in the lower part 31 of the frame 3. Rainwater that has entered the gap 40 between the outer and inner panels 1 and 2 passes through the drainage hole 41 and is discharged to the front side of the outer panel 1 (outside of the rainproof panel for housing). ing.

As can be understood from the present embodiment, the drain hole 41 can be provided in the frame 3 instead of being provided in the outer panel 1. Although it is preferable to drain the rainwater to the outdoor side rather than the rainproof panel for a house, when rainwater is allowed to drain to the indoor side rather than the rainproof panel for a house, for example, FIG. ), A drain hole 41 may be provided in the lower portion of the inner panel 2. In the present invention, the drain holes may be provided not only at one place but also at a plurality of places. Further, the specific shape and size of the drain hole are not limited.

  In the embodiment shown in FIG. 6C, the first ventilation hole 10 a located in the lower region of the outer panel 1 among the plurality of first ventilation holes 10 has a lower end portion of the frame body 3. It is provided so as to be substantially the same height as the upper surface 31a of the lower part 31, and is configured to also serve as a drainage hole. That is, when rainwater that has entered the gap 40 between the outer and inner panels 1 and 2 flows down onto the upper surface 31a of the lower portion 31 of the frame 3, the rainwater passes through the first ventilation hole 10a and the front side ( It is configured to be discharged to the front side in the figure. As can be understood from the present embodiment, the first ventilation hole can be also used as a rainwater drainage hole. Instead of the first vent hole, the second vent hole can be configured as a rainwater drain hole.

  The residential rainproof panel P4 shown in FIG. 7 is configured as a shielding member for the veranda 95 of the house. More specifically, the residential rainproof panel P4 is used by being fixedly attached to the upper portion of the handrail portion 95a of the veranda 95, and is a space portion above the handrail portion 95a (part indicated by reference numeral A1). ) Is formed in a size that can be closed.

The configuration provided by shifting the position so as not to face each other) is the same as that of the rainproof panel for a house of the embodiment described above.

  According to the rainproof panel P4 for a house of this embodiment, it is possible to make the ventilation of the veranda 95 good and to make the daylighting good while appropriately preventing rain from blowing into the veranda 95 of the house. It is. If at least one of the outer and inner panels 1 and 2 is made into a corrugated plate shape, a blinding effect that suppresses the inside of the veranda 95 from being exposed to the outside from the outside can be obtained by utilizing the refractive action of light. Also useful. As understood from this embodiment, the rainproof panel for a house according to the present invention can be used not only as a door for a window but also as a shielding member installed on a veranda. If it is a place which prevents the blowing of rain, it can be installed and used in various places.
