Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a surface lattice that is attached to a window frame or the like so that the inside of the room cannot be seen from the outside.

[Conventional technology]

Conventionally, in order to prevent the interior from being seen from the exterior and not impair ventilation, a grid as shown in FIG. 10 has been attached to a window frame or the like. In this grid, a rectangular frame is formed by upper and lower horizontal frame members 100, 100 and left and right vertical frame members 101, 102, and both ends of each of the plurality of bent blade members 103 are connected to the vertical frame member 101. , 102 at predetermined intervals. The rectangular frame of such a grid is attached to a window frame or the like from the outside of the window using fasteners or the like.

[Problem that the invention attempts to solve]

However, the blade material 103 used for the above-mentioned surface lattice is generally made of aluminum. However, aluminum has no light-permeability, so in recent years, glass or synthetic resins have been used that have both light-permeability and ventilation. These items are used with a satin pattern on the entire surface so that they are not visible from outside.
Therefore, when the upper bent portion 103a of the blade material 103 and the lower bent portion 103b of the blade material 103 arranged in parallel to the upper side of the blade material 103 are attached so as to overlap, that portion There is a problem in that the color becomes darker and color unevenness of light and light horizontal stripes occurs on the surface lattice.

In addition, when the blades 103 are installed in an overlapping manner as described above, the amount of sunlight entering the room from the outside is reduced due to the dark overlapped parts, making it dark, and the uneven color of the horizontal stripes of light and shade makes the room darker. You begin to feel a sense of pressure. Therefore, on the contrary, it would be better to have a transparent part like a so-called bamboo blind, where the outside can be seen from inside the room and the inside of the room cannot be seen from the outside, as this would brighten the room and create a sense of openness, making it a desirable surface lattice. Become.

[Means to solve the problem]

The surface lattice of the present invention was created in view of the above circumstances,
In a surface lattice in which a plurality of semi-transparent blades are attached in parallel at regular intervals to a support material with the upper and lower edges overlapping each other in horizontal view, at least one of the overlapping upper and lower edges of the blades is transparent. It is characterized by being made into an area.

[Effect of invention]

In the surface lattice constructed as described above, a transparent area and a semi-transparent area are formed in the blade material, and at least one of the upper edge and the lower edge of the blade material is attached so that the upper and lower edges overlap when viewed horizontally. is a transparent area, so the color in the overlap area does not become darker. On the other hand, when transparent areas are formed on both the upper and lower edges of the above-mentioned blade materials, the overlapping portions of the upper and lower edges of the adjacent blade materials become transparent, making it difficult to see the inside of the room from the outside like a bamboo blind. However, it is easier to see the outside from inside the room, and the light coming in from this transparent overlap area brightens the room, creating a sense of openness.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a surface lattice according to an embodiment of the present invention, FIG. 2 is a perspective view of a blade material used in the surface lattice of the same embodiment, and FIG. 3 is a perspective view of the same blade material. It is an enlarged sectional view of the main part, and FIG. 4 shows a partially cutaway perspective view showing the assembled state of the same blade material.

This surface lattice 1 consists of a pair of supporting members 3, 3 that hold a plurality of blade members 2 at regular intervals and parallel to each other.
The upper and lower ends of the support members 3, 3 are fixed to the horizontal frame members 4, 5. Above feather material 2
is bent and consists of a central portion 21, an upper bent portion 22 at the top, and a lower bent portion 23 at the bottom. Two rectangular openings 21a are formed in the central portion 21 through which the supporting members 3 are inserted, and the supporting members 3 allow the blade members 2 to be spaced at regular intervals and parallel to each other, as will be described later. It is mounted as follows.
In addition, a protrusion 22a having a semicircular roundness is formed at the tip of the upper bent portion 22 on the surface side to ensure the strength of the upper bent portion 22 and to prevent rainwater from entering. Also, safety is taken into consideration to prevent fingertips from being cut by the protrusions 22a during construction. A protrusion 23a having a semicircular roundness is formed on the back side at the tip of the lower bent part 23, and as described above, this protrusion 23a is designed to reinforce the lower bent part 23 and take safety into consideration. It is provided. In addition, this blade material 2 is extrusion molded from a transparent synthetic resin such as polycarbonate or vinyl chloride, and only the upper edge 2 to 3 mm above the approximate center of the upper bent portion 22 has a smooth surface. The other part is roughened with a so-called embossed roll or the like to form a translucent region 2a. If the surface is roughened using a textured roll, etc., the light transmittance can be freely adjusted by changing the size, depth, density, etc. of the unevenness, so that the desired light transmittance, For example, it is possible to obtain a semi-transparent region 2a with a total light transmittance of 80-95%.

The support material 3 for attaching a plurality of such blade materials 2 in parallel at regular intervals is made of synthetic resin or metal, and as shown in FIG.
It is divided into two U-shaped pillars 31 and 32. A plurality of mounting grooves 33 are diagonally formed in one column 31 for arranging a plurality of blade members 2 in parallel at regular intervals, and horizontal frames are provided on the bottom walls of each column 31 and 32. Attachment strip holes 34, 35 are provided for fasteners 36 to be fixed to the support attachment plates 4a, 5a of the members 4, 5. To attach the blade material 2 to the supporting material 3, attach one pillar 31 to the central part 2 of the blade material 2.
The opening 21a of the blade material 2 is inserted into the opening 21a of the blade material 2 into the mounting groove 33 provided in the pillar 31, and as shown in FIG. , and the semi-transparent area 2a of the lower bent portion 23 are overlapped in a horizontal view, and the other pillar 32
This is done by inserting the blade into the opening 2a of the blade material 2. Then, the support material mounting plates 4a and 5a of the horizontal frame members 4 and 5 are applied to both upper and lower edges of the support material 3, and fasteners 36 such as screws are screwed into the mounting strip holes 34 and 35. , 5a, and inserting the support mounting plates 4a, 5a along the insertion guides 4b, 5b of the upper and lower horizontal frames 4, 5, thereby assembling the surface lattice 1.

The surface lattice 1 with the blade material 2 assembled in this way
Since the transparent area 2b at the upper edge of the blade material 2 and the lower bent portion 23 of the semi-transparent area 2a of the adjacent blade material 2 overlap in a horizontal view, the color of the overlapped part L1 is dark. As a result, the surface lattice 1 has a uniform color without causing color unevenness of horizontal stripes.

Note that the transparent area 2b of the feather material 2 is located at the lower bent portion 23.
Even if it is provided only on the lower edge below the approximate center of the blade, and the other parts are semi-transparent area 2a, the color of the area where the upper and lower edges of adjacent blade materials overlap becomes darker. It can be used in the same way.

Next, FIG. 6 shows another example of the blade material 6. This blade material 6 is transparent and has a smooth surface similar to that of the previous embodiment at the upper edge above the substantially central portion of the upper bent portion 62 and the lower edge below the approximately central portion of the lower bent portion 63. The structure is the same as that of the blade material 2 of the previous embodiment, except that the area 6b is formed and the other part is a semi-transparent area 6a with a roughened surface as described above. Explanation will be omitted. As shown in FIG. 7, such a blade member 6 is attached in parallel to the support member 3 with the transparent areas 6b and 6b of the upper and lower edges of the vertically adjacent blade members 6 overlapping each other. Therefore, this overlap portion L2 becomes transparent, so that such a surface grating 1
In 1, the outside can be easily seen from inside the room through the transparent overlap part 12, and the inside can be seen easily from the outside through the transparent part, similar to a so-called bamboo blind, which improves lighting and brightens the room. The feeling of pressure indoors is also reduced.

Furthermore, FIG. 8 shows still another example of the blade material 7. The blade material 7 has a transparent region 7 having a smooth surface extending from the approximate center of the upper bent portion 72 to the upper edge thereof.
b, the lower edge from the approximate center of the lower bent portion 73 is a semi-transparent region 7a with a roughened surface, and the other parts are a semi-transparent region 7a with a roughened surface and a smooth transparent region. The structure of the blade member 2 of the previous embodiment is the same as that of the blade member 2 of the previous embodiment except that the blade members 7b and 7b are alternately formed, so the explanation thereof will be omitted here. When such a blade material 7 is used, the effect similar to that of a bamboo blind is stronger than that of the screen lattice 11 shown in the previous embodiment, making it difficult to see inside the room from the outside through the transparent part, making it easier to see the outside from inside the room, and improving the lighting performance. As things get better, the room becomes brighter and the feeling of pressure indoors is reduced. In particular, when the translucent region 7a is formed to have a width of about 2 to 4 mm, the same effect as that of the blinds will be noticeable.

Here, in order to attach the upper and lower edges of the blade material to the support material in parallel at regular intervals while overlapping each other, a hollow columnar support material 8 is inserted into the opening 21a of the blade material 2 as shown in FIG. However, spacers 9 and 10 may be fitted between the horizontal frame members 4 and 5 and the blade material 2 and between the blade members 2, respectively. Furthermore, the vertical frame member 10 shown in FIG.
The blade members may be inserted into each groove 103 provided in each of the grooves 1, 102 and attached so as to maintain a constant interval.

Note that the roughened semi-transparent region formed on the blade material may be formed on the back surface instead of the front surface as in the embodiment, or may be formed on both the front and back surfaces.
Furthermore, the above-mentioned semi-transparent region is not limited to being formed by roughening the surface as in the example, but can also be formed by applying a paint or by applying a pigment or the like on the top of the transparent resin using a two-layer extrusion method. Various methods can be employed, such as forming a translucent area by overlapping and extruding mixed colored resins.

[Effect of idea]

As is clear from the above explanation, in the surface lattice of the present invention, either the upper edge or the lower edge of the blade material attached with the upper and lower edges overlapping in horizontal view is defined as a transparent area, and the transparent area is The blade material is attached so that the upper edge or lower edge of the area overlaps with the adjacent blade material, and the overlap part of the blade material becomes darker in color, resulting in a surface lattice that does not cause color unevenness of horizontal stripes. On the other hand, when transparent areas are formed on both the upper and lower edges of the blade material, the overlapping area between the upper and lower edges of the adjacent blade material becomes transparent, so it is difficult to see the inside of the room from the outside like a bamboo blind. The exterior is easy to see from inside the room, and the light coming in from this transparent overlapping area brightens the room, creating a surface lattice that gives a sense of openness.
