Description
特許法第３０条第２項適用 令和２年１月２４日出願人である株式会社オガワから株式会社マツキンに本願発明に係る遮光具が取り付けられた内照式サインを納入Application of Article 30, Paragraph 2 of the Patent Act On January 24, 2020, the applicant, Ogawa Co., Ltd., delivered an internally illuminated sign equipped with a light shielding device according to the claimed invention to Matsukin Co., Ltd.
本発明は、内照式サインの筐体フレームに形成される水抜き孔に対し設けられる遮光具及び遮光具の取付方法に関するものである。 The present invention relates to a light shielding device provided for a drain hole formed in a housing frame of an internally illuminated sign, and a method for attaching the light shielding device.
内照式サインは屋外に設置されるため雨に晒されることが前提であり、内部に水が浸入し難いように作られている。
しかし、完全に内部への水の浸入を防ぐことはできないので、図１２に示すように内照式サイン１の筐体フレーム２下部には水抜き孔３が設けられている（例えば、特許文献１参照）。
Internally illuminated signs are installed outdoors and are expected to be exposed to rain, so they are designed to prevent water from penetrating inside.
However, since it is not possible to completely prevent water from entering the interior, a water drain hole 3 is provided at the bottom of the housing frame 2 of the internally illuminated sign 1, as shown in FIG. (see 1).
しかし単にこの水抜き孔３を形成するだけでは水抜き孔３を介して虫が内照式サイン１の内部に入ってきてしまう。
また、内照式サイン１内部の光が水抜き孔３から外部へ漏れ出ることで、夜間における内照式サイン１の見栄えが設計通りにならなくなる。
However, if this drain hole 3 is simply formed, insects will enter the inside of the internally illuminated sign 1 through the drain hole 3.
Moreover, the light inside the internally illuminated sign 1 leaks to the outside from the drain hole 3, so that the internally illuminated sign 1 does not look as designed at night.
そこで、図１３及び図１４に示すような遮光板２１０と防虫網２２０からなる遮光具２００が使用されている。
詳しくは、内照式サイン１の設置状態における最下部に水抜き孔３が形成されており、内照式サイン１の内部から防虫網２２０で水抜き孔３を塞ぎ、その防虫網２２０の上から遮光板２１０を被せ、溶接部２０１を形成し遮光板２１０が固定されてなる。
Therefore, a light shielding device 200 consisting of a light shielding plate 210 and an insect screen 220 as shown in FIGS. 13 and 14 is used.
Specifically, a drain hole 3 is formed at the lowest part of the internally illuminated sign 1 when it is installed, and the drain hole 3 is blocked with an insect screen 220 from inside the internally illuminated sign 1, and the drain hole 3 is closed from the inside of the internally illuminated sign 1 with an insect screen 220. A light shielding plate 210 is placed over the top, a welded portion 201 is formed, and the light shielding plate 210 is fixed.
しかしながら、このような遮光具２００においては防虫網２２０が詰まりやすく、それに伴って内照式サイン１内部に雨水が溜まることがある。これにより、内部の汚れやＬＥＤの故障等が発生する。
また、防虫網２２０や遮光板２１０の取り付けに手間が掛かってしまう。
However, in such a light shielding device 200, the insect screen 220 is likely to become clogged, and accordingly, rainwater may accumulate inside the internally illuminated sign 1. This causes internal contamination and LED failure.
Further, it takes time and effort to attach the insect screen 220 and the light shielding plate 210.
そこで、本発明の目的とするところは、十分な排水機能を有し、しかも取り付けが容易な遮光具及び遮光具の取付方法を提供することにある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a light shielding device that has a sufficient drainage function and is easy to install, and a method for attaching the light shielding device.

図１乃至図１０、及び図１２を参照して、本発明の実施形態に係る遮光具１００及び遮光具１００の取付方法を説明する。
まず、遮光具１００について説明する。
遮光具１００とは、図１２に示すような内照式サイン１の筐体フレーム２に形成される水抜き孔３に対し設けられ、内照式サイン１内部の水を排水可能かつ水抜き孔３から内照式サイン１内部への光漏れを防止可能とするものである。
この遮光具１００は、クリップ１０と、遮光キャップ２０と、を備える。
A light shielding tool 100 and a method of attaching the light shielding tool 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10 and 12.
First, the light shielding tool 100 will be explained.
The light shielding device 100 is provided for the water drain hole 3 formed in the housing frame 2 of the internally illuminated sign 1 as shown in FIG. 3 to the inside of the internally illuminated sign 1 can be prevented.
This light shielding tool 100 includes a clip 10 and a light shielding cap 20.
クリップ１０は、本体部１１と、先端部１２と、第一爪部１３と、第二爪部１４と、を備え、プラスチック（耐久性及び耐候性に優れるポリカーボネートが好ましい）で成型される。
本体部１１は、下方が開口した略コ字状であり、その幅は筐体フレーム２の水抜き孔３の直径と略等しいが若干小さい。なお、幅方向は厚さ方向とは直交する向きである。
The clip 10 includes a main body portion 11, a tip portion 12, a first claw portion 13, and a second claw portion 14, and is molded from plastic (preferably polycarbonate, which has excellent durability and weather resistance).
The main body part 11 has a substantially U-shape with an open bottom, and its width is substantially equal to the diameter of the drain hole 3 of the housing frame 2, but slightly smaller. Note that the width direction is perpendicular to the thickness direction.
先端部１２は、首部１２ａと頭部１２ｂからなり、本体部１１の上部中央から首部１２ａが突出し、上方に縮径する略円錐状の頭部１２ｂが首部１２ａの上に設けられている。
首部１２ａの直径は本体部１１の厚さと略等しく、本体部１１の幅よりは小さい。また、首部１２ａの直径は後述する遮光キャップ２０の平面部２１に形成された孔部２１ａの直径よりも小さい。
頭部１２ｂの下端の直径は首部１２ａの直径よりも大きい。
The distal end portion 12 includes a neck portion 12a and a head portion 12b. The neck portion 12a projects from the center of the upper portion of the main body portion 11, and a substantially conical head portion 12b whose diameter decreases upward is provided on the neck portion 12a.
The diameter of the neck portion 12a is approximately equal to the thickness of the main body portion 11, and smaller than the width of the main body portion 11. Further, the diameter of the neck portion 12a is smaller than the diameter of a hole portion 21a formed in a flat portion 21 of the light-shielding cap 20, which will be described later.
The diameter of the lower end of the head 12b is larger than the diameter of the neck 12a.
第一爪部１３は、本体部１１の上下方向略中央であって幅方向外側に一対設けられており、それぞれが上方から下方になるにつれ幅方向外側に大きくなるよう傾斜している。
二つの第一爪部１３の外側先端間の距離は水抜き孔３の直径よりも長い。
A pair of first claw portions 13 are provided at approximately the center in the vertical direction of the main body portion 11 and on the outer side in the width direction, and each of the first claw portions 13 is inclined so as to increase outward in the width direction from the top to the bottom.
The distance between the outer tips of the two first claws 13 is longer than the diameter of the drain hole 3.
第二爪部１４は、本体部１１の下端の幅方向外側両側に突出するように一対設けられている。
また、第二爪部１４は第一爪部１３の下方に位置し、第二爪部１４と第一爪部１３との距離は筐体フレーム２の厚さに略等しい。
そして、水抜き孔３にクリップ１０が挿入された状態において、第二爪部１４と第一爪部１３とで筐体フレーム２を挟持可能となっている。なお、この挟持とは第二爪部１４と筐体フレーム２間、また第一爪部１３と筐体フレーム２間に隙間が全く無いことを意味するものではない。
A pair of second claw portions 14 are provided so as to protrude from both widthwise outer sides of the lower end of the main body portion 11 .
Further, the second claw portion 14 is located below the first claw portion 13, and the distance between the second claw portion 14 and the first claw portion 13 is approximately equal to the thickness of the housing frame 2.
When the clip 10 is inserted into the drain hole 3, the second claw part 14 and the first claw part 13 can hold the housing frame 2. Note that this clamping does not mean that there is no gap at all between the second claw part 14 and the housing frame 2 or between the first claw part 13 and the housing frame 2.
遮光キャップ２０は、平面部２１と、複数の突起部２２と、を備え、可撓性を有する軟質材からなる。本実施形態においては難燃性及び耐候性に優れるシリコンゴム製とした。
平面部２１は、略円盤状で略中央には孔部２１ａが形成されている。
この孔部２１ａの直径はクリップ１０の首部１２ａの直径より大きく、クリップ１０の頭部１２ｂの直径より小さい。
また、平面部２１の上面を白く塗装している。
The light shielding cap 20 includes a flat portion 21 and a plurality of protrusions 22, and is made of a flexible soft material. In this embodiment, it is made of silicone rubber, which has excellent flame retardancy and weather resistance.
The plane portion 21 has a substantially disk shape and has a hole 21a formed substantially in the center.
The diameter of this hole 21a is larger than the diameter of the neck 12a of the clip 10 and smaller than the diameter of the head 12b of the clip 10.
Further, the upper surface of the flat portion 21 is painted white.
突起部２２は、平面部２１の下面の縁近傍から複数垂下して、それらが略円形に配置され第一円を形成し、平面部２１の孔部２１ａを囲んでいる。突起部２２の一つ一つは略楕円柱状で、それぞれの高さは等しい。
また、第一円のそれぞれの突起部２２ａ同士は等間隔に離間している。
A plurality of protrusions 22 hang down from near the edge of the lower surface of the plane part 21 , are arranged in a substantially circular shape, form a first circle, and surround the hole 21 a of the plane part 21 . Each of the protrusions 22 has a substantially elliptical column shape and has the same height.
Further, the respective projections 22a of the first circle are spaced apart from each other at equal intervals.
この突起部２２ａからなる第一円の内側に、同様に複数の突起部２２ｂを配置して第二円を形成した。第二円における突起部２２ｂ同士も第一円における突起部２２ａと同様に互いに等間隔に離間している。
そして、第一円の複数の突起部２２ａと第二円の複数の突起部２２ｂを周方向について互い違いになっている。
A plurality of protrusions 22b were similarly arranged inside the first circle made up of the protrusions 22a to form a second circle. The protrusions 22b in the second circle are equally spaced apart from each other like the protrusions 22a in the first circle.
The plurality of protrusions 22a in the first circle and the plurality of protrusions 22b in the second circle are alternated in the circumferential direction.
言い換えると、第一円の複数の突起部２２ａ間の空隙の周方向内側に、第二円の突起部２２ｂをそれぞれ配置することで、平面部２１を周方向外側から見たとき、第一円の複数の突起部２２ａ間の空隙を第二円の突起部２２ｂで塞ぐようにしている。
つまり、第一円の突起部２２ａの周方向の長さは第二円の突起部２２ｂ間の空隙の周方向の長さよりも長く、第二円の突起部２２ｂの周方向の長さは第一円の突起部２２ａ間の空隙の周方向の長さよりも長い。
In other words, by arranging the protrusions 22b of the second circle on the circumferentially inner side of the gaps between the plurality of protrusions 22a of the first circle, when the plane part 21 is viewed from the outside in the circumferential direction, The gaps between the plurality of protrusions 22a are filled with the second circular protrusions 22b.
That is, the circumferential length of the first circular protrusion 22a is longer than the circumferential length of the gap between the second circular protrusions 22b, and the circumferential length of the second circular protrusion 22b is longer than the circumferential length of the gap between the second circular protrusions 22b. It is longer than the circumferential length of the gap between the circular protrusions 22a.
また、クリップ１０が回転しないように平面部２１には回り止め部２３が設けられている。 Further, a rotation preventing portion 23 is provided on the flat portion 21 to prevent the clip 10 from rotating.
次に、このような遮光具１００を内照式サイン１の筐体フレーム２に取り付ける取付方法について説明する。
まず、図７及び図８に示すように内照式サイン１の外側（下方）からクリップ１０を水抜き孔３に対し挿入する。挿入時にはクリップ１０の第一爪部１３が水抜き孔３の縁部を乗り越え、圧入するようになる。
そして、第一爪部１３が水抜き孔３の縁部を乗り越えたら、筐体フレーム２を第一爪部１３と第二爪部１４で挟持する状態となる。
Next, a method of attaching such a light shielding tool 100 to the housing frame 2 of the internally illuminated sign 1 will be described.
First, as shown in FIGS. 7 and 8, the clip 10 is inserted into the drain hole 3 from the outside (lower side) of the internally illuminated sign 1. At the time of insertion, the first claw part 13 of the clip 10 goes over the edge of the drain hole 3 and is press-fitted.
When the first claw part 13 gets over the edge of the drain hole 3, the housing frame 2 is held between the first claw part 13 and the second claw part 14.
次に、突出部がクリップ１０側になるように遮光キャップ２０をクリップ１０に対し近付け、平面部２１の孔部２１ａにクリップ１０の先端部１２を圧入し、図６及び図９に示すように遮光キャップ２０に対してクリップ１０を嵌合させる。
このようにして筐体フレーム２の水抜き孔３に対して遮光具１００が取り付けられる。
ここで、筐体フレーム２の水抜き孔３への遮光具１００の取付けに際し、治具等を必要としない。
Next, the light-shielding cap 20 is brought closer to the clip 10 so that the protruding part is on the clip 10 side, and the tip part 12 of the clip 10 is press-fitted into the hole 21a of the flat part 21, as shown in FIGS. 6 and 9. The clip 10 is fitted onto the light shielding cap 20.
In this way, the light shielding tool 100 is attached to the drain hole 3 of the housing frame 2.
Here, no jig or the like is required when attaching the light shielding tool 100 to the drain hole 3 of the housing frame 2.
以上のように構成された遮光具１００及び遮光具１００の取付方法によれば、遮光キャップ２０が、平面部２１の下面からから垂下しそれぞれ離間するとともに略円形に配置されて孔部２１ａを囲む複数の突起部２２を備えるので、十分な排水機能を有する。
また、遮光キャップ２０にはクリップ１０の先端部１２を圧入可能な孔部２１ａが形成されているので、筐体フレーム２に対して遮光具１００を取り付け容易である。しかも取り付けに際して治具等も必要としない。
According to the light shielding device 100 and the method of attaching the light shielding device 100 configured as described above, the light shielding caps 20 hang down from the lower surface of the plane portion 21, are spaced apart from each other, and are arranged in a substantially circular shape to surround the hole portion 21a. Since it includes a plurality of protrusions 22, it has a sufficient drainage function.
Further, since the light shielding cap 20 is formed with a hole 21a into which the tip 12 of the clip 10 can be press-fitted, the light shielding tool 100 can be easily attached to the housing frame 2. Furthermore, no jigs or the like are required for installation.
また、複数の突起部２２を第一円とその内側の第二円の二重の略円状に配置され、第一円の突起部２２ａと第二円の突起部２２ｂを周方向について互い違いに配置したので、遮光性が高く、水抜き孔３から内照式サイン１の外部へ光が漏れ難い。
さらに、遮光キャップ２０が可撓性を有する軟質材からなるので、図１１に示すように筐体フレーム２が曲面になっている部分であっても遮光具１００を取付けることができる。
Further, the plurality of protrusions 22 are arranged in a double substantially circular shape of a first circle and a second circle inside thereof, and the protrusions 22a of the first circle and the protrusions 22b of the second circle are arranged alternately in the circumferential direction. Because of this arrangement, light shielding properties are high, and light does not easily leak from the drain hole 3 to the outside of the internally illuminated sign 1.
Furthermore, since the light-shielding cap 20 is made of a flexible soft material, the light-shielding tool 100 can be attached even to a curved portion of the housing frame 2, as shown in FIG.
また、遮光キャップ２０の平面部２１の上面を白く塗装したので、内照式サイン１の表面に光ムラが生じにくく内照式サイン１の外観を損なわない。 Furthermore, since the upper surface of the flat part 21 of the light-shielding cap 20 is painted white, light unevenness is less likely to occur on the surface of the internally illuminated sign 1, and the appearance of the internally illuminated sign 1 is not impaired.
なお、本実施形態において、遮光キャップ２０の複数の突起部２２を二重の略円状に配置したが、これに限られるものではなく、複数の突起部２２を一重の略円状にしても排水機能が高く、筐体フレーム２への取付けは容易である。また、複数の突起部２２の配置が一重でも全く遮光しないわけではない。 In the present embodiment, the plurality of protrusions 22 of the light shielding cap 20 are arranged in a double substantially circular shape, but the present invention is not limited to this, and the plurality of protrusions 22 may be arranged in a single substantially circular shape. It has a high drainage function and is easy to attach to the housing frame 2. Further, even if the plurality of protrusions 22 are arranged in one place, it does not mean that light is not blocked at all.
また、遮光キャップ２０は可撓性を有する軟質材からなるとしたが、これに限られるものではない。 Moreover, although the light-shielding cap 20 is made of a flexible soft material, it is not limited to this.
また、遮光キャップ２０の平面部２１の上面を白く塗装したが、これに限られるものではない。
さらに、クリップ１０の素材をポリカーボネートとしたが、これに限られるものではなく、ポリアセタールやナイロン等であってもよい。
Further, although the upper surface of the flat portion 21 of the light shielding cap 20 is painted white, the present invention is not limited to this.
Furthermore, although the clip 10 is made of polycarbonate, it is not limited to this, and may be made of polyacetal, nylon, or the like.
