The packing material 30 has protruded parts 32 that are arranged on a plane in contact with the peripheral part of the irradiation port 25 and go round the irradiation port 25 along the packing material 30, and main body protruded parts 27 that go round the irradiation port 25 along the protruded parts 32 of the packing material 30 are arranged on a plane in contact with the packing material 30 in the peripheral part of the irradiation port 25. In a fitted state, the protruded parts 32 are crushed to contribute to increasing a contact area and enhancing the pressing force owing to a restoring force. The main body protruded parts 27 serve as a breakwater to prevent water intrusion and are embedded in the packing material 30 to contribute to increasing a contact area and enhancing the pressing force owing to the restoring force.

Description

本発明は、パッキンにより防水された灯器および防水構造に関する。   The present invention relates to a lamp and a waterproof structure that are waterproofed by packing.

街路灯など屋外に設置される灯器では、発光部や駆動回路などを保護するために防水性が要求される。たとえば、本体に開口された光の照射口とこの照射口を覆うガラス板などの透光板との境界部での防水性を確保するために、これらの境界にゴム等のパッキンが嵌め込まれる（特許文献１参照。）。   Lamps installed outdoors such as street lamps are required to be waterproof in order to protect the light emitting section and the drive circuit. For example, in order to ensure waterproofness at the boundary between a light irradiation port opened in the main body and a light-transmitting plate such as a glass plate covering the irradiation port, packing such as rubber is fitted to these boundaries ( (See Patent Document 1).

特開２００４−１１１２８４号公報JP 2004-111284 A 特許第４３７１９０２号Japanese Patent No. 4371902

通常、パッキンの接触面は平坦であり、このようなパッキンの場合、十分な力でパッキンを押し付けなければ防水性を確保できず、押し付け力の不足は防水不良の原因になる。   Normally, the contact surface of the packing is flat. In such a packing, the waterproofness cannot be secured unless the packing is pressed with a sufficient force, and the lack of pressing force causes a waterproof failure.

特許文献１に開示の防雨型照明器具では、パッキンの外面に突起を設けると共に、これに対応する凹部を器具側の接触面に設けている。この構成では、平坦な接触面に比べて接触面積が増えるので、ある程度の防水性能の向上は期待できる。しかし、大部分は平坦な接触面での接触であり、また、凹部に突起が嵌り込むので、突起の潰れも少なく、押し付け力は増加しない。   In the rainproof type lighting fixture disclosed in Patent Document 1, a projection is provided on the outer surface of the packing, and a corresponding recess is provided on the contact surface on the fixture side. In this configuration, since the contact area increases compared to a flat contact surface, a certain degree of improvement in waterproof performance can be expected. However, most of the contact is made on a flat contact surface, and the protrusion is fitted into the recess, so that the protrusion is not crushed and the pressing force does not increase.

本発明は、上記の問題を解決しようとするものであり、パッキンにより高い防水性能が確保された灯器および防水構造を提供することを目的としている。   The present invention is intended to solve the above problem, and an object thereof is to provide a lamp and a waterproof structure in which high waterproof performance is ensured by packing.

かかる目的を達成するための本発明の要旨とするところは、次の各項の発明に存する。   The gist of the present invention for achieving the object lies in the inventions of the following items.

ことを特徴とする灯器。 [1] A main body having an opening for light irradiation;
A light emitting unit housed in the main body;
A translucent plate covering the irradiation port;
An annular and elastic packing that is sandwiched between portions where the periphery of the irradiation port and the translucent plate that covers the irradiation port are opposed to each other;
A fixing portion for fixing the light transmitting plate so that the packing is pressed between the light transmitting plate and the peripheral portion;
Have
The packing has a convex portion that makes a round along the packing on the contact surface with the peripheral portion of the irradiation port,

上記発明では、透光板と照射口の周辺部との間でパッキンが押圧されるようにして透光板を照射口に取り付けたとき、パッキンに設けた凸部は照射口の周辺部との接触面に当接して潰れて、接触面積が増加し、また潰れた凸部の復元力によってパッキンを照射口の周辺部に押し付ける押し付け力が強化される。一方、照射口の周辺部に設けた凸部は、パッキンを押圧してパッキンを凹ませ、パッキンの中に埋め込まれる。これにより、接触面積が増加し、またパッキンの復元力によって押し付け力が強化される。さらに、照射口の周辺部に設けた凸部は浸水を防止する防波堤として機能する。これらにより高い防水性能が確保される。   In the above-described invention, when the light-transmitting plate is attached to the irradiation port so that the packing is pressed between the light-transmitting plate and the peripheral portion of the irradiation port, the convex portion provided on the packing is connected to the peripheral portion of the irradiation port. The contact area increases and the contact area increases, and the pressing force for pressing the packing against the periphery of the irradiation port is enhanced by the restoring force of the collapsed convex portion. On the other hand, the convex part provided in the peripheral part of the irradiation opening presses the packing to dent the packing and is embedded in the packing. Thereby, a contact area increases and pressing force is strengthened by the restoring force of packing. Furthermore, the convex part provided in the peripheral part of the irradiation port functions as a breakwater that prevents inundation. These ensure high waterproof performance.

The lamp according to [1] or [2].

上記発明では、溝部の中に透光板の周縁が挟みこまれるので、パッキンと透光板との間の防水性が高められる。また、パッキン側の凸部および照射口の周辺部の凸部によってパッキンは応力を受けるので、溝部の内壁が透光板を押圧してそれらの密着が高まり、パッキンと透光板との間の防水性能が向上する。   In the said invention, since the periphery of a translucent board is inserted | pinched in a groove part, the waterproofness between packing and a translucent board is improved. In addition, since the packing is stressed by the convex portion on the packing side and the convex portion on the periphery of the irradiation port, the inner wall of the groove portion presses the translucent plate to increase their adhesion, and the gap between the packing and the translucent plate is increased. Waterproof performance is improved.

［４］前記パッキンの凸部は複数本設けられ、
前記照射口の周辺部の凸部は、前記パッキンの凸部と交互に嵌り合うように複数本設けられる

The street light 2 is installed at the side of the road or at the corner of the intersection, and functions to illuminate the road and its surroundings from above. The street light 2 is composed of a support column 3 standing vertically from the ground, and a lamp 10 attached to the upper end of the support column 3 to illuminate the lower part.

図２は、灯器１０を斜め前方上方から見た斜視図である。図３は、灯器１０の正面、下面、上面、背面、側面を示す。灯器１０は、下面側に光の照射口を有する筐体１１と、この筐体１１に収容された複数の発光モジュールと、発光モジュールを駆動する図示省略の制御回路などで構成される。   FIG. 2 is a perspective view of the lamp device 10 as viewed obliquely from above and forward. FIG. 3 shows the front, bottom, top, back, and side of the lamp 10. The lamp 10 includes a housing 11 having a light irradiation port on the lower surface side, a plurality of light emitting modules housed in the housing 11, a control circuit (not shown) that drives the light emitting modules, and the like.

灯器１０の筐体１１は、本体部２０と、上蓋部４０と、開閉カバー１２とから構成される。本体部２０は、灯器１０を支柱３に固定するための金具や発光モジュールの制御回路を収容する基部２１と、基部２１から前方へ延設された本体底面部２２とから構成される。開閉カバー１２は、基部２１の上面を開閉可能に覆う。   The housing 11 of the lamp device 10 includes a main body portion 20, an upper lid portion 40, and an opening / closing cover 12. The main body 20 includes a base 21 that houses a metal fitting for fixing the lamp 10 to the column 3 and a control circuit for the light emitting module, and a main body bottom 22 that extends forward from the base 21. The opening / closing cover 12 covers the upper surface of the base portion 21 so as to be opened and closed.

上蓋部４０は、本体底面部２２の上に被せてネジ止めされ、本体底面部２２と組み合わされて略長方形の薄い中空の箱形状を形成する。この中に発光モジュールが収容される。   The upper lid portion 40 is screwed on the main body bottom surface portion 22 and is combined with the main body bottom surface portion 22 to form a substantially rectangular thin hollow box shape. The light emitting module is accommodated in this.

本体部２０（透光板２６を除く）、上蓋部４０、開閉カバー１２はそれぞれ、溶かした金属を鋳型に流し込み、冷却、凝固させて製作された鋳造品である。   The main body 20 (excluding the translucent plate 26), the upper lid 40, and the open / close cover 12 are cast products manufactured by pouring molten metal into a mold, cooling, and solidifying.

図４は、本体部２０を示す斜視図である。基部２１から延びる本体底面部２２は、横長の略長方形の平らな底板部２３と、その周縁から上向きに立設された側壁２４と、底板部２３の中央に開口された該底板部２３より一回り小さい略長方形の照射口２５と、この照射口２５を内側から覆うようにパッキン３０を挟んで取り付けられる透光板２６とを備えて構成される。透光板２６は、光を透過する板状部材であり、ガラスや樹脂などで構成される。図４はパッキン３０および透光板２６を取り外した状態を示している。   FIG. 4 is a perspective view showing the main body 20. The bottom surface portion 22 of the main body extending from the base portion 21 is made up of a horizontally long, substantially rectangular flat bottom plate portion 23, a side wall 24 erected upward from the periphery thereof, and the bottom plate portion 23 opened at the center of the bottom plate portion 23. A substantially rectangular irradiation port 25 that is small in size and a translucent plate 26 that is attached with a packing 30 sandwiched so as to cover the irradiation port 25 from the inside. The translucent plate 26 is a plate-like member that transmits light, and is made of glass, resin, or the like. FIG. 4 shows a state where the packing 30 and the translucent plate 26 are removed.

照射口２５の周辺部を成す底板部２３の内側面には、照射口２５に沿って照射口２５の外側を一周する環状の凸部（本体側凸部２７とする）が、一回りずつ大きくなるように、３重にして、３本設けてある。   On the inner side surface of the bottom plate portion 23 that forms the periphery of the irradiation port 25, an annular convex portion (referred to as a main body side convex portion 27) that goes around the outer side of the irradiation port 25 along the irradiation port 25 is enlarged one by one. As shown, three are provided in triplicate.

図５は、パッキン３０の平面図、図６はパッキン３０のＡ−Ａ断面図である。パッキン３０は、照射口２５より一回り大きな環状であって、弾性を有するゴムなどで形成される。パッキン３０のＡ−Ａ断面は、略コの字型を成しており、コの字の一方の腕の外面に外側へ突起する２つの凸部３２を有する。   FIG. 5 is a plan view of the packing 30, and FIG. 6 is a cross-sectional view taken along the line AA of the packing 30. The packing 30 has an annular shape that is slightly larger than the irradiation port 25 and is made of elastic rubber or the like. The AA cross section of the packing 30 is substantially U-shaped, and has two convex portions 32 projecting outward on the outer surface of one of the U-shaped arms.

断面コの字型における凹部は、パッキン３０をその環の内側に沿って一周する溝部３１を成している。パッキン３０は、この溝部３１に透光板２６の周縁が密に嵌め込まれて透光板２６に外嵌される。また、前述の２つの凸部３２は、パッキン３０の長さ方向に沿って一周する環状に形成されており、内周側と外周側の２本の環状突起となっている。   The concave portion in the U-shaped cross section forms a groove portion 31 that goes around the packing 30 along the inner side of the ring. The packing 30 is externally fitted to the translucent plate 26 by tightly fitting the periphery of the translucent plate 26 into the groove 31. Moreover, the above-mentioned two convex parts 32 are formed in the cyclic | annular form which goes around along the length direction of the packing 30, and are two annular protrusions of the inner peripheral side and the outer peripheral side.

図７は、パッキン３０の外嵌された透光板２６を固定板２８により、本体底面部２２に取り付けた状態を示している。図８は、図７のＢ−Ｂ断面を示している。   FIG. 7 shows a state in which the translucent plate 26 fitted with the packing 30 is attached to the bottom surface 22 of the main body by the fixing plate 28. FIG. 8 shows a BB cross section of FIG.

パッキン３０の外嵌された透光板２６を照射口２５を覆うようにして載せる。詳細には、パッキン３０の凸部３２を本体底面部２２の底板部２３側に向け、かつ、照射口２５の周囲に設けた本体側凸部２７の上にパッキン３０が載るようにして、透光板２６を載置して照射口２５を覆う。その後、固定板２８をパッキン３０の上に載せ、この固定板２８でパッキン３０を底板部２３に向けて押圧した状態で、固定板２８をネジ２９で本体底面部２２に取り付ける。   A translucent plate 26 fitted with the packing 30 is placed so as to cover the irradiation port 25. Specifically, the packing 30 is placed so that the convex portion 32 of the packing 30 faces the bottom plate portion 23 side of the main body bottom surface portion 22 and the main body side convex portion 27 provided around the irradiation port 25. The light plate 26 is placed to cover the irradiation port 25. Thereafter, the fixing plate 28 is placed on the packing 30, and the fixing plate 28 is attached to the bottom surface portion 22 of the main body with screws 29 while the packing 30 is pressed against the bottom plate portion 23 with the fixing plate 28.

ここでは、図７に示すように、固定板２８は、略長方形の環状を成したパッキン３０の長辺部分のみに設けられており、角の部分および短辺部分は固定板２８で押圧されていない。   Here, as shown in FIG. 7, the fixing plate 28 is provided only on the long side portion of the substantially rectangular annular packing 30, and the corner portion and the short side portion are pressed by the fixing plate 28. Absent.

図９は、透光板の取り付け前後におけるパッキン３０側の凸部３２と照射口２５の周辺部に設けた本体側凸部２７の状態を示す断面図である。同図（ａ）に示すように、パッキン３０側の２本の凸部３２と、照射口２５の周辺部に設けた３本の本体側凸部２７とは、対向しないように、位置をずらしてあり、丁度、交互に嵌りあう位置関係にされている。パッキン３０の凸部３２は、先端の尖った断面形状を成している。ここでは、先端が尖った凸部３２の断面形状として三角形を例示するが、この形状に限定されるものではない。一方、照射口２５の周辺部に設けた３本の本体側凸部２７は、先端が丸みを帯びた断面形状を成している。ここでは、先端が丸みを帯びた断面形状として略半円形を例示するが、この形状に限定されるものではない。   FIG. 9 is a cross-sectional view showing the state of the convex part 32 on the packing 30 side and the main body side convex part 27 provided in the peripheral part of the irradiation port 25 before and after the translucent plate is attached. As shown in FIG. 5A, the two protrusions 32 on the packing 30 side and the three main body side protrusions 27 provided on the periphery of the irradiation port 25 are shifted in position so as not to face each other. It is in a positional relationship that fits alternately. The convex portion 32 of the packing 30 has a cross-sectional shape with a sharp tip. Here, a triangle is illustrated as a cross-sectional shape of the convex portion 32 having a sharp tip, but the shape is not limited to this. On the other hand, the three main body side convex portions 27 provided in the peripheral portion of the irradiation port 25 have a cross-sectional shape with rounded tips. Here, a substantially semicircular shape is illustrated as a cross-sectional shape with a rounded tip, but the shape is not limited to this.

同図（ａ）の状態から固定板２８によってパッキン３０を本体底面部２２の底板部２３側に向けて押さえ込むと、パッキン３０の凸部３２は弾性変形により潰れてほぼ平らになり、本体底面部２２の底板部２３と潰れて平らになった凸部３２とが密着する（同図（ｂ））。この密着力は、弾性変形した凸部３２の復元力が加わって強化されている。なお、凸部３２は先端が尖った断面形状を成しているので、先端部分が潰れ易く、平らになり易い。   When the packing 30 is pressed toward the bottom plate 23 side of the main body bottom surface portion 22 by the fixing plate 28 from the state shown in FIG. 5A, the convex portion 32 of the packing 30 is crushed by elastic deformation and becomes almost flat. The bottom plate portion 23 of 22 and the convex portion 32 that has been flattened are brought into close contact with each other ((b) in the figure). This adhesion force is strengthened by the addition of the restoring force of the elastically deformed convex portion 32. In addition, since the convex part 32 has comprised the cross-sectional shape where the front-end | tip sharpened, the front-end | tip part is easy to be crushed and it is easy to become flat.

一方、本体側凸部２７に押圧された箇所のパッキン３０は、本体側凸部２７の形状に合わせて凹むように弾性変形し、本体側凸部２７の表面全体とほぼ密着する（同図（ｂ））。この密着力も、本体側凸部２７に押されて弾性変形したパッキン３０の復元力が加わって強められている。また、本体側凸部２７は浸水を防止する防波堤としての役目を果たし、防水性能の向上に寄与する。なお、本体側凸部２７は先端が丸みを帯びた断面形状を成しているので、パッキン３０に損傷を与えることなく、パッキン３０を凹ませて容易に弾性変形させることができる。また、パッキン３０は本体側凸部２７の先端形状に合わせて緩やかなカーブで凹めば良いので、凹んだパッキン３０と本体側凸部２７とが隙間無く密着する。   On the other hand, the packing 30 at the place pressed by the main body side convex portion 27 is elastically deformed so as to be recessed in conformity with the shape of the main body side convex portion 27, and is substantially in close contact with the entire surface of the main body side convex portion 27 (see FIG. b)). This adhesion force is also strengthened by the restoring force of the packing 30 which is pushed by the main body side convex portion 27 and elastically deformed. In addition, the main body side convex portion 27 serves as a breakwater that prevents water from entering, contributing to improvement of waterproof performance. Since the main body side convex portion 27 has a rounded cross-sectional shape, the packing 30 can be dented and easily elastically deformed without damaging the packing 30. Further, since the packing 30 may be recessed with a gentle curve in accordance with the tip shape of the main body side convex portion 27, the concave packing 30 and the main body side convex portion 27 are in close contact with each other without any gap.

このように、本発明の実施の形態に係る灯器１０では、パッキン３０に凸部３２を設けると共に、本体底面部２２の照射口２５の周辺に本体側凸部２７を設けることで、パッキン３０と本体底面部２２の底板部２３との接触面積を増やし、かつ、弾性変形の復元力を利用してパッキン３０と底板部２３との強い押し付け力が生じるので、高い防水性能を発揮することができる。   Thus, in the lamp device 10 according to the embodiment of the present invention, the packing 30 is provided with the convex portion 32, and the main body side convex portion 27 is provided around the irradiation port 25 of the main body bottom surface portion 22. Since the contact area between the main body bottom surface portion 22 and the bottom plate portion 23 is increased, and a strong pressing force is generated between the packing 30 and the bottom plate portion 23 by using the restoring force of elastic deformation, high waterproof performance can be exhibited. it can.

なお、透光板２６の周縁はパッキン３０の溝部３１に押し込まれて溝部３１の内壁に広い接触面積で密着する。また、パッキン３０側の凸部３２の潰れや本体側凸部２７の押し込みによって凹んだパッキン３０の復元力は、溝部３１の内面を透光板２６に押し付ける力として作用するので、透光板２６の周縁と溝部３１との密着力を高めて、この部分での防水性能が高められる。   In addition, the periphery of the translucent plate 26 is pushed into the groove portion 31 of the packing 30 and closely contacts the inner wall of the groove portion 31 with a wide contact area. Further, the restoring force of the packing 30 that is recessed by the crushing of the convex portion 32 on the packing 30 side or the pressing of the main body side convex portion 27 acts as a force that presses the inner surface of the groove portion 31 against the translucent plate 26. The adhesion between the peripheral edge and the groove portion 31 is enhanced, and the waterproof performance at this portion is enhanced.

本実施の形態に係る灯器１０では、上記の防水構造を採用することで、固定板２８をパッキン３０の長辺側にのみ設けても十分な防水性能が確保される。これにより、固定板２８は、単なる細長い長方形の金属片等で済み、環状に形成する場合に比べて、小型で簡素なものになる。特に、パッキン３０の角部を固定板２８で押さえ込む必要がないので、構造が簡素化される。   In the lamp 10 according to the present embodiment, by adopting the above waterproof structure, sufficient waterproof performance is ensured even if the fixing plate 28 is provided only on the long side of the packing 30. As a result, the fixing plate 28 is simply a thin and long rectangular metal piece or the like, and is smaller and simpler than the case where it is formed in an annular shape. In particular, since it is not necessary to press down the corners of the packing 30 with the fixing plate 28, the structure is simplified.

＜防水構造＞
灯器１０に採用した、凸部３２を有するパッキン３０と、本体側凸部２７を設けた本体底面部２２内面との間の防水構造は、灯器１０以外の防水を要する各種の製品に適用することができる。すなわち、物体と物体との間に弾性を有するパッキンを挟む防水構造であって、パッキンは、物体との接触面に該パッキンに沿って延びる凸部を有し、物体はパッキンとの接触面に、パッキンの凸部と位置をずらしてパッキンに沿って延びる凸部を有する防水構造であれば、灯器１０を例に説明した場合と同様の防水効果を得ることができる。この防水構造は、たとえば、カメラの防水ジャケットや水槽などに適用されてもよい。 <Waterproof structure>
