送衛星に直接向けて設置されるのが一般的とされている
。しかし、方では地上放送と同様にアンテナの室内設置
に対する要望も強い。In recent years, satellite broadcasting has spread rapidly, and commercial broadcasting has already begun in some countries. SHF radio waves used for satellite broadcasting have stronger straightness than VHF and UHF radio waves for terrestrial broadcasting, and BS antennas for reception are generally installed outdoors pointing directly at the broadcasting satellite. has been done. However, as with terrestrial broadcasting, there is a strong demand for antennas to be installed indoors.

２〜３１１Ｉｌの厚みの窓ガラスと比べて極めて高価で
あり、簡単には採用できない。When installing a BS antenna indoors, it seems impossible to receive satellite broadcasting without at least using a window. Furthermore, even if a window is used, if the window is closed with glass, the SHF radio waves are attenuated by the window glass, making it impossible to obtain a clear image. However, even if you receive satellite broadcasting through a window glass, if the window glass is about 5 meters thick,
It has been reported that the transmission loss through window glass is extremely low (the problem that the invention aims to solve).However, window glass with a thickness of around 5+ma is for special purposes.
It is not used in ordinary houses, and it is extremely expensive compared to window glass with a thickness of 2 to 311 Il used in ordinary houses, so it cannot be easily adopted.

スの貼付施工を強いるという大きな問題がある。If two sheets of temporary glass are stacked together and the total thickness is adjusted to around 5m, the transmission loss for satellite broadcasting radio waves will be improved to the same level as a single sheet of glass of around 5m, but two sheets of glass require a special window frame. , construction is extremely difficult. Further, plate glass is easily broken, and even when another plate glass is attached to the temporary glass fitted in the window frame, there is a big problem in that the recipient is forced to attach the plate glass.

It is in.
〔課題を解決するための手段〕本発明の窓ガラスは、窓枠に嵌め込まれている仮ガラス

では板ガラスの厚みに応じた複数種の厚みの樹脂板等を
用意する必要がある。When bonding another plate glass to the temporary glass, as mentioned above, it is necessary to adjust the total thickness to around 5 m. When bonding a resin plate to temporary glass, if the resin plate is bonded to one side of the glass plate, the transmission loss for satellite broadcasting radio waves will not be sufficiently improved unless the total thickness is appropriate. Therefore, in these cases, it is necessary to accurately know the thickness of the glass plate fitted into the window frame, and to select a glass plate or a resin plate with a thickness corresponding to that thickness. However, it is not easy for the recipient to accurately measure the thickness of the glass sheet fitted into the window frame, and antenna manufacturers, etc., have to measure the thickness of the glass sheet fitted into the window frame accurately. It is necessary to prepare.
その点、仮ガラスの両面に樹脂板を接合した場合は、仮
ガラスの厚みに関係なく衛星放送用電波に対する透過損
失が大幅に改善される。On the other hand, if resin plates are bonded to both sides of the temporary glass, the transmission loss for satellite broadcasting radio waves will be significantly improved regardless of the thickness of the temporary glass.

変わらない電波透過度を示す。Further, when attaching a resin plate to the temporary glass, the size of the resin plate is at least about 40CIX4Q pieces, taking into account the size of the BS antenna installed indoors. However, such large resin plates are bulky, require packaging,
Not only is shipping time-consuming, but air bubbles remain on the bonding surface when pasting it on window glass, making it difficult to do so. On this point, resin plates that are divided into multiple small pieces so that they can be pasted side by side on window glass do not take up much bulk when packaged or transported, and can be easily pasted on window glass. After they are pasted side by side, they show the same radio wave transmittance as -2 resin plates.
樹脂板における仮ガラスとの接合面に、気泡を逃がすた
めの溝を設けた場合は、樹脂板が大型のままでも比較的
簡単に貼り付け作業を行うことができる。If grooves are provided on the surface of the resin plate to be joined to the temporary glass to allow air bubbles to escape, the attachment process can be performed relatively easily even if the resin plate remains large.
樹脂板の材質としては、例えばアクリル系樹脂、ポリ塩
化ビニル系樹脂、ポリカーボネート系樹脂、スチロール
系樹脂等が好適に用いられ、透明もしくはこれに近いも
のが望ましい。As the material of the resin plate, for example, acrylic resin, polyvinyl chloride resin, polycarbonate resin, styrene resin, etc. are suitably used, and transparent or similar material is preferable.
［実施例］第１図は本発明の窓ガラスの一例を示す斜視図である。[Example]FIG. 1 is a perspective view showing an example of the window glass of the present invention.

がすためのＶ状等の溝２ａが基盤目状等に設けられる。The window glass shown in FIG. 1 has a partial three-layer structure in which resin plates 2, 2 are attached in a sandwich manner to predetermined areas on both sides of a temporary glass l fitted into a window frame. If necessary, grooves 2a, such as V-shaped grooves, are provided in the shape of the base board to allow air bubbles to escape, on the joint surface of the resin plate 2.2 with the temporary glass l.

宜法められる。The size of the resin plates 2, 2 is appropriately determined (for example, about 40C1×40cn) depending on the size of the BS antenna installed indoors. The area where the resin plate 2.2 is attached is determined as appropriate depending on the antenna installation position so that radio waves reaching a BS antenna installed indoors pass through the area where the resin plate 2.2 is attached.
樹脂板２．２の厚みについては、３ＩＩＩＩｌ１程度が
特に望ましい。このことを以下に詳しく説明する。The thickness of the resin plate 2.2 is particularly preferably about 3III11. This will be explained in detail below.

４ＩＩＩＩｌの３種類を使用し、５肺以上はこれらの組
合せとした。Tables 1 to 3 show the C/N ratio for satellite broadcasting radio waves when resin plates (acrylic resin) of various thicknesses are attached to the surface of temporary glass of various thicknesses, when there is no shielding. A comparison is made with the case where the BS antenna is covered with a single sheet of glass. The thickness of the resin plate is 2am, 3tm,
Three types of 4IIII were used, and a combination of these was used for 5 or more lungs.

ラスとを重ねて総厚を５閣にすれば、Ｃ／Ｎ比は５閣の
単体板ガラスと同じ１３，５が確保される。Table 1 The C/N ratio is 14 when the BS antenna is installed without any obstructions. Also, the BS antenna is 5II
C/N ratio when shielded with 11 plate glass is 13.5
It is. When the plate glass is 31111, the C/N ratio is 9.
However, if 31111 temporary glass and 2m temporary glass are stacked to make the total thickness 5 sheets, the C/N ratio will be 13.5, which is the same as 5 sheets of single plate glass.
これらの従来例に対し、３ｍｓの板ガラスの片面に樹脂

／Ｎ比は１２，５以上が確保され、６ｍ１１では総厚５
ｆｆｌ１１の板ガラスと同しＣ／Ｎ比（１３，５）が確
保される。In contrast to these conventional examples, when a resin plate is bonded to one side of a 3ms plate glass, the C/N is 12.0 when the total thickness is 3m, and the C/N is 12.0 when the total thickness is 2-6m. The ratio is 1
000 or more is ensured. When bonding resin plates to both sides of the plate glass of 3-, the total thickness is 411III or more and C
/N ratio is ensured at 12.5 or more, and the total thickness is 5 at 6m11.
The same C/N ratio (13,5) as the sheet glass of ffl11 is ensured.
板ガラスの厚みが２１１Ｉ１１の場合は、その片面に５
Ｉ１ｍ厚の樹脂板を接合することによりＣ／Ｎ比は１０

By joining resin plates with a thickness of I1m, the C/N ratio is 10.
．． 5, but the improvement effect is not as great as when bonding on both sides.
板ガラスの厚みが４ｍの場合は、その片面に樹脂板を接
合すると、Ｃ／Ｎ比はむしろ低下する。If the thickness of the plate glass is 4 m, if a resin plate is bonded to one side of the plate glass, the C/N ratio will actually decrease.
しかし、両面に接合することにより、５ｍ厚の板ガラス
並までＣ／Ｎ比が改善される。However, by bonding on both sides, the C/N ratio can be improved to the same level as a 5 m thick plate glass.
以上より明らかなように、仮ガラスの片面に樹脂板を接

ラスの両面に３−厚の樹脂板を接合した場合のＣ／Ｎ比

と同レベルになる。As is clear from the above, if a resin plate is bonded to one side of the temporary glass, the C/N ratio is improved except when the thickness of the temporary glass is close to 5IllI. However, even if the C/N ratio is improved, a sufficient improvement effect can only be obtained at a specific thickness corresponding to the thickness of the plate glass, and even if it is sufficient, the C/N ratio is comparable to that of a 5u thick plate glass. However, if a resin plate is bonded to both sides of the temporary glass, the C/N ratio can be obtained almost regardless of the thickness of the glass plate, and regardless of the thickness of the resin plate, the C/N ratio is the same as that of temporary glass with a thickness of 5 sheets. The resulting C/N ratio, especially when 3-thick resin plates are bonded to both sides of a plate glass, is at the same level as a 511 Im thick plate glass, regardless of the thickness of the plate glass.

れている。The window glass shown in FIG. 2 has a structure in which a plurality of small pieces are partially pasted on both sides of a temporary glass 1 fitted into a window frame. Each small piece is a square-shaped transparent resin plate 20. An adhesive is applied to one side of each resin plate 20, and a release paper 30 is pasted on the adhesive-applied surface before use.

１枚の大型の樹脂板を貼り付けた場合と同しレヘルに抑
制される。In use, the release paper 30 is peeled off from each resin #l 120, and the resin plates 20 are pasted on opposite square areas on both sides of the plate glass l without any gaps. By doing so, the resin plate 20 can be easily adhered to a predetermined area on both sides of the glass plate 1 without forming bubbles, and the transmission loss of SHF radio waves in that area can be reduced by applying one sheet on each side of the temporary glass l. It is suppressed to the same level as when a large resin plate is attached.

紙箱等に樹脂板２０を収納することも可能になる。Furthermore, before use, by overlapping each resin plate 20, the resin plate 20 is stored in a small size, and as a result, the resin plate 20 can be easily packed, transported, etc., and sold as a set with the BS antenna. In this case, it is also possible to store the resin plate 20 in a paper box or the like in which the BS antenna is packed.

剥離に伴う被害を抑えることができる。Furthermore, even if the resin plate 20 attached to the glass plate 1 were to peel off, only partial peeling would suffice, so damage caused by the peeling would be minimized. In addition, if the resin board is a single piece that is not divided, attach it to a hook etc. attached to the window frame.
By connecting the window panels with wires, strings, etc.
Damage caused by peeling can be suppressed.
樹脂Ｆｉ２０は、上記実施例では正方形状とされている

たり、四角形以外の多角形状等に貼り付けることも可能
である。Although the resin Fi 20 has a square shape in the above embodiment, it may have a rectangular shape, a triangular shape, or even other polygonal shapes. It is also possible to paste it into a polygonal shape or the like.

望ましい。The number and width of the resin plates 20 are determined appropriately based on the ease of handling and pasting of the resin plates 20, and the size of the area on the temporary glass l to which the resin plates 20 are to be attached, and are usually about lQcm square. Attach about 16 pieces of paper to one side. In addition, as with a single resin plate, in the case of single-sided adhesive, the thickness of the temporary glass l should be adjusted so that the transmission loss for SHF radio waves after the resin plate 20 is attached is as small as possible. In the case of double-sided adhesive, it is preferably about 3 cm, regardless of the thickness of the plate glass l.

。If the resin eff20 is 311II thick, 11 cm, and 11 ai, an area of 44 cm x 44 cm can be covered with the resin plates 20 by pasting 32 resin plates 20, 16 each in a square shape, on opposing areas on both sides of the glass plate 1 without gaps. The C/N ratio for satellite broadcasting radio waves is 13.5.

。更に樹脂板は取り扱い易く、割れの危険もない。The window glass for indoor reception of satellite broadcasting of the present invention exhibits excellent transparency for SHF radio waves used in satellite broadcasting, and is inexpensive because conventional window glass can be used as is. Furthermore, the resin plate is easy to handle and there is no risk of cracking.
