Description

  The present invention relates to a technique for shielding solar radiation in an insect screen door attached to an opening such as a window of a building.

  Insect screens attached to the opening of a building are usually used in summer to prevent insects from entering from the outside to indoors, while at the same time allowing ventilation through the screens.

The insect net of this insect screen is constructed by knitting vertical and horizontal lines of the same diameter, and the size of the gap between the horizontal lines adjacent to each other vertically and the vertical lines adjacent to the left and right (that is, mesh 5). The size is set so as to prevent insects from entering at the same time while ensuring the air flow. For example, in FIGS. 4 and 5, the diameter A of the horizontal line 3 and the diameter C of the vertical line 4 are each 0.26 mm, and the pitch of the horizontal line 3 (the dimension E between the centers of the adjacent horizontal lines 3 from the center of the horizontal line 3) and The pitch of the vertical lines 4 (dimension F between the centers of the vertical lines 4 adjacent to the vertical line 4) is 1.411 mm, the distance B between the horizontal lines 3 and the distance D between the vertical lines 4 Are set to 1.15 mm, so that 18 vertical lines 4 and 3 are provided in one inch, which satisfies the number in one inch in the screen doors defined in JIS A4709. The area of the gap portion (mesh 5) surrounded by the horizontal line 3 adjacent vertically and the vertical line 4 adjacent right and left is 1.15 mm × 1.15 mm≈1.3 mm ² . The relationship between the diameter A of the horizontal line 3 and the dimension B of the interval between the horizontal lines 3 is A = 0.226B in the above-described conventional insect screen door.

  In the conventional example having the above-described configuration, as shown in FIG. 4, direct sunlight X enters the room from the mesh 5 part of the insect screen 2 of the insect screen in the direction of southeast to south to southwest in the summer. It is like that. As described above, the conventional insect screen has a direct cool air in the room through the mesh 5 of the insect screen 2 even though it takes in the outside air through the mesh 5 of the insect screen 2 in summer to obtain a cool breeze. There is a problem that sunlight X is inserted, the indoor temperature becomes high, and the indoor environment is deteriorated.

  On the other hand, it is known from Patent Document 1 that an insect screen itself is formed of a bright material having a high light reflectance so that the heat of direct sunlight is reduced into the room. Patent Document 2 discloses a light reflection layer provided on the outer surface.

However, in these patent documents 1 and patent documents 2, it is possible to reflect the direct sunlight hitting the vertical and horizontal lines in the insect screen of the insect screen, but in the direction from southeast to south to southwest in the summer, the direct sunlight is reflected. Can not be prevented from being inserted into the room through the mesh, and even in this case, the direct sunlight enters the room from the mesh of the insect screen in the summer, and heat is taken into the room, which deteriorates the indoor environment. Still remains.

  The present invention has been invented in view of the above-described conventional problems, and provides a solar-shielded insect-proof screen door in which the horizontal line of the insect-repellent net functions as a hook for the mesh so that direct sunlight cannot be easily inserted into the room. It is to be an issue.

  In order to solve the above-mentioned problem, the sunscreen insect-proof screen door according to the present invention is configured such that the diameter A of the horizontal line 3 of the insect-proof net 2 in the insect screen 1 is 0.3 to 0.5 times the dimension B of the distance between the upper and lower horizontal lines 3. It is characterized by being set to.

  By adopting such a configuration, in the insect screen 2 of the insect screen 1 having an insect repellent function and a ventilation function, the horizontal line 3 of the insect screen 2 in the insect screen 1 is in the direction from southeast to south to southwest in the summer. It functions as a kite and prevents direct sunlight X from entering the room during the summer. Further, in the winter season, since the solar altitude is low, it is possible to take heat directly into the room by acquiring direct sunlight X from the mesh 5 of the insect screen 1 through the sash door with the translucent sash door 7 closed. .

  In addition, it is preferable that the diameter C of the vertical line 4 of the insect screen 2 is smaller than the diameter A of the horizontal line 3 and the interval D between the vertical lines 4 is set longer than the interval B between the horizontal lines 3.

  With such a configuration, the diameter A of the horizontal line 3 is set to 0.3 to 0.5 times the dimension B of the distance between the upper and lower horizontal lines 3, and the direct sunlight X is indoors in the summer as described above. Despite not being inserted, the area of the mesh 5 necessary for ventilation can be ensured, and a sufficient amount of ventilation can be obtained through the insect-proof net 2.

The present invention can prevent insects and aeration performance, prevent direct sunlight from entering the room from the mesh in the summer, does not receive heat from the sun, and closes the translucent sash door in the winter. You can get direct sunlight from the screen of the insect screen through the sash door and take heat into the room.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 3, the insect screen 1 is attached to the opening 6 of the building, and a sash door 7 having translucency is attached to the opening 6 of the building so as to be freely opened and closed, and the sash door 7 is opened. In this case, the insect screen 1 is positioned at the portion where the sash door 7 is opened, so that the insect screen 2 of the insect screen 1 prevents the insects from entering the room from the outside and vents through the mesh 5 of the insect screen 2. It can be done.

  The insect screen 1 is constructed by stretching an insect screen 2 on a screen frame 8, and the insect screen 2 is constructed by knitting a number of horizontal lines 3 and a number of vertical lines 4, as shown in FIG.

  In the present invention, as shown in FIGS. 1 and 2, the diameter A of the horizontal line 3 of the insect screen 2 is set to 0.3 to 0.5 times the dimension B of the distance between the upper and lower horizontal lines 3. is there. That is, A is set to 0.3 to 0.5B. Thus, by setting the diameter A of the horizontal line 3 of the insect repellent net 2 to 0.3 times or more the distance B between the upper and lower horizontal lines 3 (that is, the vertical width of the mesh 5), Will function as a wrinkle in the mesh 5.

  That is, when the eaves 11 are projected from the outer wall 10 of the building, summer direct sunlight is prevented from entering the room through the windows 12 in the direction from southeast to south to southwest (that is, the sunlight from the windows due to eaves). In FIG. 6, the protruding length M of the ridge 11 protruding outside from the outer wall 10 in FIG. 6 is about 0 to 3 times the height H from the lower end of the ridge 11 to the lower end of the window 12. (See “Explanation of energy-saving standards for houses” published by the Building Environment and Energy Conservation Organization). In other words, the length M of the ridge 11 is set to 0 or 3 times the height H from the lower end of the ridge 11 to the lower end of the window 12, so that the ridge 11 is oriented in the direction from southeast to south to southwest in the summer. Thus, it is possible to prevent direct sunlight X from being inserted into the room from the window 12.

  Therefore, in the present invention, the diameter A of the horizontal line 3 of the insect screen 2 of the insect screen 1 is not less than 0.3 times the dimension B of the distance between the upper and lower horizontal lines 3 in the same manner as the relationship between the ridge 11 and the window 12. By doing so, the insect screen 1 is in the southeast to south to southwest orientation, and direct sunlight in the summer is blocked by the horizontal line 3 so that it can be radiated from the mesh 5 into the room.

  On the other hand, in the present invention, the diameter A of the horizontal line 3 of the insect screen 2 is set to 0.5 times or less of the distance B between the upper and lower horizontal lines 3. If the distance B between the horizontal lines 3 is 0.5 times or more than the dimension B, the insect screen 1 is shielded by the horizontal lines 3 in the direction from southeast to south to southwest and the solar radiation cannot be obtained from the mesh 5 even in winter. If the diameter of the horizontal line 3 becomes larger than necessary, or if the distance B between the upper and lower horizontal lines 3 becomes narrower than necessary, the material cost will increase or the necessary ventilation rate will not be obtained. Therefore, in consideration of these points, in the present invention, the diameter A of the horizontal line 3 of the insect net 2 is set to 0.5 times or less the dimension B of the distance between the upper and lower horizontal lines 3.

  Further, as shown in FIG. 2, the diameter C of the vertical line 4 of the insect screen 2 is smaller than the diameter A of the horizontal line 3 described above, and the distance between the vertical lines 4 than the distance B between the horizontal lines 3. D is set longer. Thus, the diameter C of the vertical line 4 of the insect screen 2 is smaller than the diameter A of the horizontal line 3 described above, and the distance D between the vertical lines 4 is set longer than the distance B between the horizontal lines 3 as described above. In addition, the diameter A of the horizontal line 3 of the insect screen 2 is set to 0.3 to 0.5 times the distance B between the upper and lower horizontal lines 3 so that the direct sunlight X does not enter the room in the summer as described above. Nevertheless, the area of the mesh 5 necessary for ventilation can be ensured while ensuring the insect repellent function, and a sufficient amount of ventilation can be obtained through the insect repellent net 2.

  In the embodiment shown in FIGS. 1 and 2, for example, the diameter A of the horizontal line 3 is 0.41 mm, the diameter C of the vertical line 4 is 0.23 mm, and the pitch of the horizontal line 3 (the horizontal line 3 adjacent from the center of the horizontal line 3). The dimension E between the centers of the vertical lines 4 and the pitch of the vertical lines 4 (the dimension F between the centers of the vertical lines 4 adjacent to the center of the vertical lines 4) are both 1.411 mm (this is the same as the conventional example in FIG. 5). ), The distance B between the horizontal lines 3 is set to 1.001 mm, and the distance D between the vertical lines 4 is set to 1.18 mm. In this embodiment, A≈0.4B.

The area of the gap portion (that is, mesh 5) surrounded by the horizontal line 3 adjacent to the top and bottom and the vertical line 4 adjacent to the left and right is 1.001 mm × 1.18 mm≈1.2 mm ² . Accordingly, the pitch of the horizontal line 3 (dimension E between the center of the horizontal line 3 and the center of the adjacent horizontal line 3) and the pitch of the vertical line 4 (dimension F between the center of the vertical line 4 and the center of the adjacent vertical line 4) are illustrated. 5 in which the number of horizontal lines 3 and vertical lines 4 in one inch is the same as that in the conventional example, and in the embodiment of the present invention, A≈0.4B, Thus, in the summer, the horizontal line 3 functions as a trap and the solar radiation is not inserted into the room through the mesh 5, so that the area of the mesh 5 can be made almost the same as the conventional example shown in FIGS. The air flow rate does not decrease, and substantially the same air flow rate can be secured, and insects can be prevented from entering the room from the outside through the mesh 5.

  In the present invention, as described above, it has insect repellent performance and ventilation performance, and further, the diameter A of the horizontal line 3 is set between the upper and lower horizontal lines 3 so that the direct sunlight X in the summer does not enter the room through the mesh 5. As long as it is set to 0.3 to 0.5 times the dimension B, the number is not limited to the above value, and the number of vertical lines 4 and horizontal lines 3 in one inch is also limited to the above example. Not.

  Further, the horizontal lines 3 and vertical lines 4 of the insect screen 2 of the insect screen 1 of the present invention are formed of a bright material having a high light reflectance, or a light reflecting layer is provided on the surface of the insect screen 2 on the outdoor side. May be. In this case, the heat generated by the reflection of the direct sunlight X by the horizontal lines 3 and 4 of the insect repellent net 2 does not enter the room, and the direct sunlight by the function of the horizontal line 3 in summer as described above passes through the mesh 5. Therefore, the insect screen door 1 can radiate heat in the summer due to the effect that the heat due to not being inserted into the room does not enter the room.

  On the other hand, since the solar altitude is lower in the winter than in the summer, the direct sunlight X is obtained from the mesh 5 of the insect screen 1 through the glass of the sash door 7 with the translucent sash door 7 closed. Heat can be taken into.
