Description
【０００１】[0001]
本考案は、器具本体をグローブで覆う防水型照明器具に関するものである。 The present invention relates to a waterproof lighting fixture that covers a fixture body with a glove.
【０００２】[0002]
上記のような防水型照明器具として、従来は図２に示すようなものがあった。 すなわち、図２に示すように、ソケット１４を設けた器具本体１５を本体用パッ キン１６を介して取付面８に取着し、透光性を有し樹脂成形された半球状のグロ ーブ１７と器具本体１５とにねじ山１５ａ，１７ａを設け、防水パッキン１８を 挟んで器具本体１５にグローブ１７を螺合していた。 As a waterproof luminaire as described above, there has conventionally been one as shown in FIG. That is, as shown in FIG. 2, the instrument main body 15 provided with the socket 14 is attached to the mounting surface 8 via the main body packing 16, and the translucent resin-molded hemispherical globe is formed. Threads 15a and 17a are provided on the instrument body 15 and the instrument body 15, and the glove 17 is screwed to the instrument body 15 with the waterproof packing 18 sandwiched therebetween.
【０００３】 しかし、上記の従来構成では、器具本体１５とグローブ１７との間で大きな締 付力が得られるので密閉性は高いが、器具本体やグローブの形状が限定されると いう問題があった。 また、別の従来例として図３に示すようなものがあった。図３に示すように、 ソケット１４を設けた器具本体１９の外周に枠体２０を配設し、防水パッキン２ １を被着したグローブ２２の開口周端部２２ａを枠体２０と器具本体１９とで挟 持してナット２３で締め付け固定していた。However, in the above-described conventional configuration, since a large tightening force can be obtained between the device body 15 and the glove 17, the sealing performance is high, but there is a problem that the shapes of the device body and the glove are limited. It was Another conventional example is shown in FIG. As shown in FIG. 3, a frame body 20 is arranged on the outer periphery of the instrument body 19 provided with the socket 14, and the opening peripheral end portion 22a of the globe 22 to which the waterproof packing 21 is attached is attached to the frame body 20 and the instrument body 19. It was clamped by and clamped and fixed by the nut 23.
【０００４】 上記の従来構成では、樹脂成形された枠体２０やグローブ２２に局部的な応力 が加わらないので、工具による締め付けが可能で高い密閉性が得られるが、堅牢 な枠体２０を必要とし、また工具を使うために施工に手間がかかるという問題が あった。 さらに、上述した２つの従来例においては、永久圧縮歪を生じにくいソリッド のゴムパッキンを使用し強固に固定することができるが、樹脂製のグローブの温 度・湿度による収縮により繰り返しストレスが加わり、割れ等が生じるという問 題があった。In the above-described conventional configuration, since no local stress is applied to the resin-molded frame 20 or the globe 22, it is possible to tighten with a tool and obtain high sealing performance, but a robust frame 20 is required. In addition, there is a problem that it takes a lot of time and labor for the construction because a tool is used. Furthermore, in the two conventional examples described above, solid rubber packing, which is unlikely to cause permanent compression strain, can be used for firm fixation, but repeated stress is applied due to shrinkage of the resin gloves due to temperature and humidity. There was a problem that cracks and the like would occur.
【０００５】[0005]
一方、図４（ａ），（ｂ）に示すように、直管形ランプ２４が装着された器具 本体２５を防水パッキン２６を介して取付面８に取着し、開口部を備えた略函状 のグローブ２７を器具本体２５に覆着してつまみねじ１０でグローブ２７を器具 本体２５に締め付け固定している場合、グローブ２７の開口周端部２７ａが防水 パッキン２６に圧接される圧接力を得るために、防水パッキン２６として可撓性 のある発泡ゴム製のものを使用している。 On the other hand, as shown in FIGS. 4 (a) and 4 (b), an instrument main body 25 having a straight tube lamp 24 attached thereto is attached to a mounting surface 8 via a waterproof packing 26, and a schematic box having an opening is provided. When the glove 27 in the shape of a circle is covered on the device body 25 and the glove 27 is fastened and fixed to the device body 25 with the thumbscrew 10, the opening peripheral end portion 27a of the glove 27 is pressed against the waterproof packing 26 with a pressing force. In order to obtain it, the waterproof packing 26 is made of flexible foam rubber.
【０００６】 しかし、上記構成では、発泡ゴム製の防水パッキン２６の初期の密閉性は高い が、発泡ゴムは塑性変形を起こし易く、経時変化により密閉性が低下するという 問題がある。 また、図５に示すように、チューブ状に中空押出成形し、可撓性を有しつつ復 元力を備えた防水パッキン２８を用いた場合、グローブ２９の周縁に段部２９ａ を設ける必要があり外観上見苦しいという問題や、防水パッキン２８の影ができ るという問題がある。However, in the above configuration, although the waterproof rubber packing 26 made of foamed rubber has a high initial sealing property, there is a problem that the foamed rubber is likely to be plastically deformed and the sealing property is deteriorated due to aging. Further, as shown in FIG. 5, when the waterproof packing 28 which is hollow extruded into a tubular shape and is flexible and has a restoring force is used, it is necessary to provide a step 29a on the periphery of the globe 29. There is a problem that the outer appearance is unsightly, and a problem that the waterproof packing 28 has a shadow.
【０００７】 さらに、前者の構成においては、図４（ａ）に示すように、つまみねじ１０で 器具本体２５に締め付け固定されたグローブ２７の両端近傍部、すなわちつまみ ねじ１０の周囲の部分と、グローブ２７の中央寄りの部分とでは、グローブ２７ の開口周端部２７ａが防水パッキン２６を圧接する力にばらつきが生じ、中央寄 りの部分の密閉性が低くなるという問題がある。また、樹脂成形したグローブ２ ７の開口周端部２７ａは、図４（ａ）の点線で示すように内側に反る傾向があり 、照明器具を壁に配置した場合にグローブ２７の中央寄りの部分に水が溜まり易 く、しかもその部分の密閉性が低いことと相まって浸水の恐れがあるという問題 がある。Further, in the former configuration, as shown in FIG. 4 (a), a portion near both ends of the globe 27 clamped and fixed to the instrument body 25 by the thumb screw 10, that is, a portion around the thumb screw 10, There is a problem that the opening peripheral end portion 27a of the globe 27 has a variation in force with which the waterproof packing 26 is pressed against the portion near the center of the glove 27, and the hermeticity of the portion near the center is lowered. Further, the opening peripheral end portion 27a of the resin-molded globe 27 tends to warp inward as shown by the dotted line in FIG. 4 (a), and when the lighting fixture is placed on the wall, it is closer to the center of the globe 27. There is a problem that water is likely to accumulate in the part and that there is a risk of flooding due to the low sealing property of the part.
【０００８】 本考案は上記問題点の解決を目的とするものであり、グローブを防水パッキン に圧接することで充分な密閉性が得られる防水型照明器具を提供しようとするも のである。The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a waterproof luminaire in which sufficient tightness can be obtained by pressing a globe against a waterproof packing.

以下、本考案の一実施例を図面を参照して説明する。 図１（ａ）に本考案の一実施例の一部破断した側面図を示す。図１（ａ）に示 すように、照明器具１は、全周にわたる周縁部１ａを備え、周縁部１ａから表面 方向に段差１ｂを設けて平板状に形成されている。したがって、段差１ｂを設け ることにより平板状の器具本体１の強度を上げ、薄板で器具本体１を形成するこ とが可能になる。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1A shows a partially broken side view of an embodiment of the present invention. As shown in FIG. 1 (a), the lighting fixture 1 is provided with a peripheral edge portion 1a over the entire circumference, and is formed in a flat plate shape by providing a step 1b in the surface direction from the peripheral edge portion 1a. Therefore, by providing the step 1b, it is possible to increase the strength of the flat plate-shaped instrument body 1 and form the instrument body 1 with a thin plate.
【００１４】 そして、器具本体１の表面の一方の側に、片持装着ランプ２を取り付けるソケ ット３を配設した支持板４を立設し、さらに、器具本体１の表面の他方の側に点 灯装置５を取着した取付板６を支持板４と対向させて立設している。この支持板 ４と取付板６とは、いずれも平板状の部材の対向する辺をそれぞれ同じ側に略直 角に折り曲げて形成してあり、一方の折曲部４ａ，６ａには器具本体１の裏面側 から器具本体１を挿通させ、ビス９を挿入するビス孔を設け、それぞれビス９に より器具本体１に固定している。また、支持板４と取付板６のもう一方の折曲部 ４ｂ，６ｂにはつまみねじ１０を挿通するねじ孔４ｃ，６ｃが設けてある。Then, a support plate 4 having a socket 3 for mounting the cantilever mounting lamp 2 is erected on one side of the surface of the instrument body 1, and the other side of the surface of the instrument body 1 is further erected. Further, a mounting plate 6 to which the lighting device 5 is attached is erected so as to face the support plate 4. The supporting plate 4 and the mounting plate 6 are both formed by bending opposite sides of a flat plate-shaped member to the same side in a substantially right angle. The instrument main body 1 is inserted from the back side of the, and screw holes for inserting the screws 9 are provided, and each is fixed to the instrument main body 1 with the screw 9. Further, the other bent portions 4b and 6b of the support plate 4 and the mounting plate 6 are provided with screw holes 4c and 6c through which the thumbscrews 10 are inserted.
【００１５】 上記のように構成した器具本体１と取付面８との間に平板状の防水パッキン１ １を介装し、器具本体１を取付面８に取着している。この防水パッキン１１は、 器具本体１の周縁部１ａより外方へ突出させた縁部を器具本体１の段差１ｂに向 けて延伸して段差１ｂに当接させるとともに段差１ｂに沿って周縁部１ａの方へ 垂下し、周縁部１ａとの間に空所１１ｂを設けて成る受部１１ａを備えている。 また、この受部１１ａは周縁に向けて取付面８の方へ下がるテーパ状に形成して いる。A flat-plate waterproof packing 11 is interposed between the instrument body 1 and the mounting surface 8 configured as described above, and the instrument body 1 is attached to the mounting surface 8. The waterproof packing 11 has an edge projecting outwardly from the peripheral edge 1a of the instrument body 1 extending toward the step 1b of the instrument body 1 so as to abut against the step 1b, and along the edge 1b. It is provided with a receiving portion 11a that hangs down toward 1a and has a space 11b provided between it and the peripheral edge portion 1a. Further, the receiving portion 11a is formed in a taper shape that is lowered toward the mounting surface 8 toward the peripheral edge.
【００１６】 一方、図１（ａ）及び（ｂ）に示すように、グローブ１２は開口部１２ａを備 えた山形の略函状に形成し、このグローブ１２を器具本体１の表面側に覆着して 器具本体１の全体をグローブ１２内に収納している。また、グローブ１２の内側 面の支持板４と取付板６の折曲部４ｂ，６ｂに対向する部分を内側へ突出させた 突出部１２ｄ，１２ｄを折曲部４ｂ，６ｂに当接させ、折曲部４ｂ，６ｂに設け たねじ孔４ｃ，６ｃと挿通するつまみねじ用ねじ孔１２ｃ，１２ｃをこの突出部 １２ｄ，１２ｄにそれぞれ設けている。よって、器具本体１に覆着したグローブ １２のつまみねじ用ねじ孔１２ｃ，１２ｃと折曲部４ｂ，６ｂに設けたねじ孔４ ｃ，６ｃとにねじパッキン１３を介してつまみねじ１０を挿通して締めつけ、グ ローブ１２を器具本体１に固定している。On the other hand, as shown in FIGS. 1 (a) and 1 (b), the globe 12 is formed in a substantially box-like shape having an opening 12 a, and the globe 12 is attached to the front side of the instrument body 1. Then, the entire instrument body 1 is stored in the glove 12. Also, the projections 12d and 12d, which are the inner surfaces of the globe 12 and the portions facing the bent portions 4b and 6b of the support plate 4 and the mounting plate 6, are protruded inward, are brought into contact with the bent portions 4b and 6b, Screw holes 12c and 12c for thumb screws, which are inserted into the screw holes 4c and 6c provided in the curved portions 4b and 6b, are provided in the protrusions 12d and 12d, respectively. Therefore, the thumbscrew 10 is inserted through the screw packing 13 into the screw holes 12c, 12c for the thumb screw of the glove 12 covered with the instrument body 1 and the screw holes 4c, 6c provided in the bent portions 4b, 6b. Then, the globe 12 is fixed to the instrument body 1.
【００１７】 ここで、図１（ｃ）に示すように、つまみねじ１０でグローブ１２を締め付け ると、防水パッキン１１の受部１１ａは段差１ｂの方へたわむ。しかし、受部１ １ａと器具本体１の周縁部１ａとの間には空所１１ｂが存在し、たわんだ受部１ １ａは段差１ｂに当接支持されるので、グローブ１２の開口周端部１２ｂと器具 本体１の周縁部１ａとの隙間を受部１１ａにより密閉して防水することができる 。Here, as shown in FIG. 1C, when the glove 12 is tightened with the thumbscrew 10, the receiving portion 11a of the waterproof packing 11 bends toward the step 1b. However, since there is a space 11b between the receiving portion 11a and the peripheral edge portion 1a of the instrument body 1 and the bent receiving portion 11a is abutted against and supported by the step 1b, the opening peripheral end portion of the globe 12 is closed. The gap between 12b and the peripheral portion 1a of the instrument body 1 can be sealed by the receiving portion 11a for waterproofing.
【００１８】 また、グローブ１２の開口周端部１２ｂは、両端側に比較して中央寄りの部分 が図１（ｃ）の点線で示すように内側へ反っている。しかし、防水パッキン１１ の受部１１ａは周縁に向けて取付面８の方へ下がるテーパ状に形成しているので 、内側に反ったグローブ１２の中央寄りの部分が先に受部１１ａに圧接すること になる。したがって、グローブ１２の開口周端部１２ｂ全体にわたって密閉性を 高め、防水性能を向上させることができる。また、テーパ状に形成した防水パッ キン１１の受部１１ａにより、内側に反ったグローブ１２の中央寄りの部分が僅 かに拡径するので、その部分に水が溜まったり、外観上見苦しくなるのを防ぐ効 果もある。さらに、グローブ１２は受部１１ａに沿って中央にガイドされるので 、つまみねじ１０のねじ部とグローブ１２のねじ用ねじ孔１２ｃとの隙間が充分 とれ、樹脂の吸湿や熱収縮に対しても余裕を持った寸法でグローブ１２を形成す ることができる。Further, the opening peripheral end portion 12b of the globe 12 is warped inward as shown by a dotted line in FIG. 1C, at a portion closer to the center than both end sides. However, since the receiving portion 11a of the waterproof packing 11 is formed in a taper shape that is lowered toward the mounting surface 8 toward the peripheral edge, the portion of the inwardly curved globe 12 near the center is pressed against the receiving portion 11a first. It will be Therefore, the airtightness can be improved over the entire opening peripheral end portion 12b of the globe 12 and the waterproof performance can be improved. In addition, the taper-shaped receiving portion 11a of the waterproof packing 11 slightly expands the inner portion of the globe 12 that is warped, so that water may accumulate in the portion and the appearance may be unsightly. It also has the effect of preventing Further, since the globe 12 is guided to the center along the receiving portion 11a, a sufficient clearance is provided between the threaded portion of the thumbscrew 10 and the threaded screw hole 12c of the globe 12, which prevents moisture absorption and heat shrinkage of the resin. It is possible to form the globe 12 with a sufficient size.
【００１９】 また、永久圧縮歪が生じにくいソリッドのゴムで防水パッキン１１を形成すれ ば、防水パッキン１１に充分な可撓性を持たせることができるので、グローブ１ ２の開口周端部１２ｂを比較的弱い力で防水パッキン１１の受部１１ａに圧接さ せても必要な密閉性を保ち充分な防水効果を得ることができる。 なお、本実施例では、片持装着ランプ２を使用する防水型照明器具について説 明したが、他の形状のランプ例えば直管形ランプや環形ランプ等を使用する防止 型照明器具であっても、本考案の技術的思想を適用することができる。Further, if the waterproof packing 11 is formed of solid rubber that is unlikely to cause permanent compression strain, the waterproof packing 11 can be provided with sufficient flexibility. Even when it is pressed against the receiving portion 11a of the waterproof packing 11 with a comparatively weak force, it is possible to maintain a necessary sealing property and obtain a sufficient waterproof effect. Although the waterproof luminaire using the cantilever-mounted lamp 2 is described in the present embodiment, a preventive luminaire using a lamp having another shape, such as a straight tube lamp or a ring lamp, may be used. The technical idea of the present invention can be applied.

The gap between the peripheral edge and the peripheral edge of the instrument body is sealed with the waterproof packing receiver to prevent There is an effect that can be. Further, the conventional waterproof packing for the instrument body and the waterproof packing for the glove are integrally formed, so that the number of parts can be reduced and the productivity such as cost can be improved. In addition, waterproof treatment can be applied at the peripheral edge of the opening of the glove, and it is possible to prevent unnecessary shading on the light-transmitting surface. This has the effect that the waterproofness is not affected by the surface finish of the mounting surface.
