Description

この発明は、航空機や船舶の事故に際し、乗員や乗客などが海上へ投げ出されたり海上へ脱出したときに表示灯が自動的に点灯して居場所を知らせるようにした救難用点灯装置に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rescue lighting device in which an indicator light is automatically turned on when a passenger or passenger is thrown out of the sea or escapes to the sea in the event of an accident of an aircraft or a ship so as to notify the location.

従来、この種の救難用点灯装置として、図６に示すように、救命胴衣１００に装着する態様のものが提案されている。この救難用点灯装置は、浸漬式電池より成る電源装置１０１と電球やＬＥＤなどの表示灯１０２とから成るもので、電源装置１０１は救命胴衣１００に設けられたポケット１００ａなどに、表示灯１０２は救命胴衣１００の肩部に設けられた取付部１００ｂに、それぞれ装着されている。電源装置１０１と表示灯１０２との間はリード線１０３により接続されている。この救命胴衣１００は、非常時に備えて飛行機や船舶に搭載されており、乗客や乗員がこの救命胴衣１００を着用して着水したとき、浸漬式電池が水に浸って起電力を発生し、電源装置１０１より表示灯１０２へ給電が行われて表示灯１０２が自動点灯する。表示灯１０２の光は上空または四方に向けて発せられ、これにより遭難者の居場所を知る手がかりとなる。   Conventionally, as this kind of rescue lighting device, as shown in FIG. 6, there has been proposed one that is attached to a life jacket 100. This rescue lighting device includes a power supply device 101 made of an immersion battery and a display lamp 102 such as a light bulb or LED. The power supply apparatus 101 is placed in a pocket 100a provided in the life jacket 100, and the display light 102 is Each is attached to a mounting portion 100 b provided on the shoulder of the life jacket 100. The power supply device 101 and the indicator lamp 102 are connected by a lead wire 103. This life jacket 100 is mounted on an airplane or a ship in case of an emergency, and when a passenger or an occupant wears the life jacket 100 and landed on the water, the immersion battery is immersed in water to generate an electromotive force, Power is supplied from the power supply apparatus 101 to the indicator lamp 102, and the indicator lamp 102 is automatically turned on. The light of the indicator light 102 is emitted toward the sky or in all directions, which provides a clue to know where the victim is.

前記浸漬式電池には、従来、水を電解液として発電する海水電池が用いられている。この種の海水電池は、ニッケル、銅などのイオン化傾向の比較的小さな金属またはその合金を用いて形成された陽極と、マグネシウム、アルミニウム、亜鉛などのイオン化傾向の比較的大きな金属またはその合金を用いて形成された陰極とを備えたもので（例えば、特許文献１）、この海水電池で発生した起電力によって表示灯１０２が点灯駆動される。   Conventionally, seawater batteries that generate electricity using water as an electrolyte are used for the immersion type batteries. This type of seawater battery uses an anode formed using a relatively low ionization metal such as nickel or copper or an alloy thereof, and a relatively high ionization metal such as magnesium, aluminum or zinc or an alloy thereof. The indicator lamp 102 is driven to be lit by the electromotive force generated in the seawater battery (for example, Patent Document 1).

特開平８−１７４４６号公報JP-A-8-17446

しかし、上記した海水電池では、水の電気分解時に発生する酸素や水素などの気体やイオンが電極部（主として陽極）に付着するため、発電性能が著しく低下し、長時間にわたって表示灯１０２を確実に点灯させることが困難である。また、この種の海水電池を電源装置１０１に用いた場合、海水電池が水に浸っている状態でなければ、起電力が得られないため、何らかの原因で海水電池が水面上に置かれたとき、表示灯１０２が消灯し、その結果、遭難者の発見を遅らせるおそれがある。さらに、海水電池は一般の乾電池に比較して高価であって簡便でなく、乾電池を電源として使用できる救難用点灯装置の出現が望まれていた。   However, in the seawater battery described above, gas and ions such as oxygen and hydrogen generated during the electrolysis of water adhere to the electrode part (mainly the anode), so that the power generation performance is remarkably lowered and the indicator lamp 102 is reliably secured for a long time. It is difficult to light up. In addition, when this type of seawater battery is used for the power supply device 101, an electromotive force cannot be obtained unless the seawater battery is immersed in water. Therefore, when the seawater battery is placed on the water surface for some reason. The indicator light 102 is turned off, and as a result, there is a risk of delaying the discovery of the victim. Furthermore, the seawater battery is expensive and simple compared to a general dry battery, and there has been a demand for the emergence of a rescue lighting device that can use the dry battery as a power source.

この発明は、電源として安価かつ簡便な乾電池を用いることができるようにして、長時間にわたり表示灯を確実に点灯させることができ、しかも、常時、水に浸っていなくても表示灯を点灯維持できる救難用点灯装置を提供することを目的とする。   This invention makes it possible to use an inexpensive and simple dry battery as a power source, so that the indicator lamp can be reliably lit for a long time, and the indicator lamp is kept lit even if it is not always immersed in water. An object of the present invention is to provide a rescue lighting device that can be used.

この発明による救難用点灯装置は、乾電池を電源とする表示灯の点灯回路中に接点機構が介装されて成る。前記接点機構は、固定接点と、固定接点に対向配置される可動接点と、水との接触により膨張して可動接点を固定接点と接触する位置まで変位させるアクチュエータとを含んでいる。前記乾電池および接点機構はケース内に、表示灯はケース外に、それぞれ配置されている。前記ケースには前記乾電池が配置される密閉された第１の室と、前記接点機構が配置される透水可能な第２の室とが設けられている。   The rescue lighting device according to the present invention is formed by interposing a contact mechanism in a lighting circuit of an indicator lamp using a dry battery as a power source. The contact mechanism includes a fixed contact, a movable contact disposed opposite to the fixed contact, and an actuator that expands by contact with water and displaces the movable contact to a position in contact with the fixed contact. The dry battery and the contact mechanism are arranged inside the case, and the indicator lamp is arranged outside the case. The case is provided with a sealed first chamber in which the dry battery is disposed and a water-permeable second chamber in which the contact mechanism is disposed.

救難用点灯装置が着水していない状態では、可動接点は固定接点から離れて定位し、接点機構は開いている。その結果、点灯回路は通電せず、表示灯は点灯しない。救難用点灯装置が着水すると、アクチュエータは水と接触して膨張するので、可動接点は固定接点と接触する位置まで変位し、接点機構が閉じる。その結果、点灯回路が通電し、表示灯が点灯する。
着水時、ケースの第１の室には水が浸入せず、乾電池は水に浸ることがないので、動作に支障をきたすおそれはない。ケースの第２の室には水が浸入するので、アクチュエータは水に浸って膨張し、接点機構が閉動作する。 When the rescue lighting device has not landed, the movable contact is positioned away from the fixed contact and the contact mechanism is open. As a result, the lighting circuit is not energized and the indicator lamp is not lit. When the rescue lighting device lands, the actuator expands in contact with water, so that the movable contact is displaced to a position in contact with the fixed contact, and the contact mechanism is closed. As a result, the lighting circuit is energized and the indicator lamp is lit.
At the time of landing, water does not enter the first chamber of the case, and the dry battery does not soak in water, so there is no possibility of hindering operation. Since water enters the second chamber of the case, the actuator expands by being immersed in water, and the contact mechanism is closed.

この発明の好ましい一実施態様においては、前記アクチュエータは水との接触により膨張する材料をもって形成された板状体であり、その板状体の一表面に可動接点が接着され、板状体の他表面がケースに固定されている。前記の「水との接触により膨張する材料」として、例えば、ＰＶＡ（ポリビニルアルコール）スポンジ、水膨張ゴム、水膨張ゴム発泡体などを用いることができる。いずれも弾力性があり、親水性、吸水性、および保水性を有している。   In a preferred embodiment of the present invention, the actuator is a plate-like body formed of a material that expands by contact with water, and a movable contact is bonded to one surface of the plate-like body, so that The surface is fixed to the case. As the above-mentioned “material that expands by contact with water”, for example, PVA (polyvinyl alcohol) sponge, water expansion rubber, water expansion rubber foam and the like can be used. All are elastic and have hydrophilicity, water absorption, and water retention.

前記乾電池は、外気温の上昇および低下により起電力の低下を招くので、外気温の変化による性能劣化を防止するために、ケースの第１の空間に熱が遮断された状態で配置するのが望ましい。ここで、熱が遮断された状態を実現するのに、乾電池の周囲に空気による断熱層を設けるようにしてもよく、また、乾電池の周囲をウレタンフォームなどの断熱材で覆うようにしてもよい。   Since the dry cell causes a decrease in electromotive force due to an increase and decrease in the outside air temperature, in order to prevent performance deterioration due to a change in the outside air temperature, the dry battery is arranged in a state where heat is blocked in the first space of the case. desirable. Here, in order to realize a state in which the heat is shut off, an air-insulating layer may be provided around the dry cell, and the dry cell may be covered with a heat insulating material such as urethane foam. .

前記可動接点が固定接点に接触し、接点機構が閉動作して点灯回路が通電したとき、前記点灯回路の通電状態を安定して保持するために、点灯回路に通電状態を保持する自己保持回路を設けるようにしてもよい。   When the movable contact contacts the fixed contact, the contact mechanism closes and the lighting circuit is energized, the self-holding circuit that maintains the energized state in the lighting circuit in order to stably maintain the energized state of the lighting circuit May be provided.

この発明によると、電源として乾電池を用いるようにしたから、長時間にわたり表示灯を確実に点灯させることができる。しかも、乾電池は安価かつ簡便であるから、救難用点灯装置のコストの低減および利便性の向上を実現できる。また、水との接触により膨張するアクチュエータにより可動接点を固定接点と接触する位置まで移動させるから、常時、水に浸っていなくても表示灯を点灯維持でき、安定した動作を実現できる。   According to this invention, since the dry battery is used as the power source, the indicator lamp can be reliably turned on for a long time. In addition, since the dry battery is inexpensive and simple, it is possible to reduce the cost and improve the convenience of the rescue lighting device. In addition, since the movable contact is moved to a position where it comes into contact with the fixed contact by the actuator that expands by contact with water, the indicator lamp can be kept lit even if it is not always immersed in water, and stable operation can be realized.

図１は、この発明の一実施例である救難用点灯装置１の外観を示している。
図示例の救難用点灯装置１は、図６に示した救命胴衣１００に装着されるもので、救命胴衣１００の胴部に形成されたポケット１００ａ内に装着される装置本体２０と、肩部に形成された取付部１００ｂに装着される表示灯２とを備えている。前記装置本体２０は４枚の側板１１〜１４と２枚の端板１５，１６とを接着して構成されるケース１０を含んでいる。前記端板１５に開設された貫通孔１５ａよりリード線３，３０がケース１０の外部へ引き出され、リード線３，３０の先端に前記表示灯２が接続されている。 FIG. 1 shows the appearance of a rescue lighting device 1 according to an embodiment of the present invention.
The rescue lighting device 1 in the illustrated example is attached to the life jacket 100 shown in FIG. 6, and includes a device main body 20 to be installed in a pocket 100 a formed in the body portion of the life jacket 100, and a shoulder portion. The indicator lamp 2 is mounted on the formed mounting portion 100b. The apparatus main body 20 includes a case 10 configured by bonding four side plates 11 to 14 and two end plates 15 and 16. The lead wires 3 and 30 are drawn out of the case 10 through the through holes 15 a provided in the end plate 15, and the indicator lamp 2 is connected to the tips of the lead wires 3 and 30.

前記表示灯２は、ＬＥＤや電球により構成されるが、その他にキセノン放電管などを用いることもできる。また、ＬＥＤとして高輝度発光のものや自己点滅タイプのものを用いてもよい。なお、表示灯２の点灯回路には必要に応じて昇圧回路などを組み込むこともできる。   Although the said indicator lamp 2 is comprised with LED and a light bulb, a xenon discharge tube etc. can also be used in addition. Moreover, you may use the thing of high-intensity light emission, and the thing of a self-flashing type as LED. Note that a booster circuit or the like can be incorporated in the lighting circuit of the indicator lamp 2 as necessary.

前記ケース１０の内部には、図２に示すように、内部の空間を区画するための仕切板１７が設けてある。この仕切板１７を挟んで一方の空間には２個の乾電池４，４を収納保持するための第１の室Ａが、他方の空間には接点機構５を設けるための第２の室Ｂが、それぞれ形成されている。前記接点機構５は乾電池４，４を電源とする表示灯２の点灯回路中に介装されるもので、図３に示すように、固定接点５１，５２に可動接点５０が接触して接点機構５が閉じたとき（同図中、一点鎖線で示す。）、点灯回路が通電して表示灯２が点灯する。   As shown in FIG. 2, a partition plate 17 for partitioning the internal space is provided inside the case 10. A first chamber A for storing and holding two dry batteries 4, 4 is provided in one space across the partition plate 17, and a second chamber B for providing the contact mechanism 5 is provided in the other space. , Each is formed. The contact mechanism 5 is interposed in the lighting circuit of the indicator lamp 2 using the dry batteries 4 and 4 as a power source. As shown in FIG. 3, the movable contact 50 comes into contact with the fixed contacts 51 and 52, and the contact mechanism. When 5 is closed (indicated by the alternate long and short dash line in the figure), the lighting circuit is energized and the indicator lamp 2 is lit.

第１の室Ａは、水が浸入しないように密閉されている。この第１の室Ａに２個の乾電池４，４を保持するための保持枠４１，４２が組み付けられている。各保持枠４１，４２には正負の各電極４３，４４がそれぞれ設けられるともに、２個の乾電池４，４を直列接続するために、一方の保持枠４１の正電極４３と他方の保持枠４２の負電極４４とがリード線３１で接続されている。一方の保持枠４１の負電極４４と接点機構５の一方の固定接点５１とはリード線３２により接続され、他方の保持枠４２の正電極４３には表示灯２に接続するためのリード線３０が接続されている。各リード線３２，３０は仕切板１７に形成された連通孔１７ａより第２の室Ｂへ導入されている。前記リード線３０は接点機構５の他方の固定接点５２に接続されたリード線３とともに、前記貫通孔１５ａよりケース外へ引き出されている。   The first chamber A is sealed so that water does not enter. In this first chamber A, holding frames 41 and 42 for holding two dry batteries 4 and 4 are assembled. The holding frames 41 and 42 are provided with positive and negative electrodes 43 and 44, respectively, and in order to connect the two dry batteries 4 and 4 in series, the positive electrode 43 of one holding frame 41 and the other holding frame 42. The negative electrode 44 is connected with the lead wire 31. The negative electrode 44 of one holding frame 41 and one fixed contact 51 of the contact mechanism 5 are connected by a lead wire 32, and the positive electrode 43 of the other holding frame 42 is connected to the indicator lamp 2 by a lead wire 30. Is connected. Each lead wire 32, 30 is introduced into the second chamber B through a communication hole 17 a formed in the partition plate 17. The lead wire 30 is drawn out of the case from the through hole 15a together with the lead wire 3 connected to the other fixed contact 52 of the contact mechanism 5.

上記の保持枠４１，４２に保持される２個の乾電池４，４は、第１の室Ａにおいて、周囲の側板１１〜１４の内面との間に空気の断熱層が介在した状態で保持されている。前記断熱層によって外部からの熱が乾電池４，４に伝達するのを阻止されるが、一層の断熱効果を得るために、第１の室Ａ内にウレタンフォームなどの断熱材を配備して乾電池４，４の周囲を覆うようにする。   The two dry batteries 4 and 4 held by the holding frames 41 and 42 are held in the first chamber A with an air heat insulating layer interposed between the inner surfaces of the surrounding side plates 11 to 14. ing. Although heat from the outside is prevented from being transferred to the dry batteries 4 and 4 by the heat insulating layer, a heat insulating material such as urethane foam is provided in the first chamber A in order to obtain a further heat insulating effect. Cover around 4 and 4.

第２の室Ｂには内部の空間を２分するための第２の仕切板１８が設けられている。この仕切板１８には接点機構５を構成する固定接点５１，５２が一定の間隔を隔てた絶縁状態で取り付けられている。この仕切板１８を挟んで一方の空間Ｂ１には接点機構５を構成する可動接点５０が配備されている。また、他方の空間Ｂ２はリード線３，３０を導出入するための空間になっている。
前記空間Ｂ１は、水が入るように前記端板１５の空間Ｂ１に対応する位置に透水用の切欠１９が形成されている。一方、空間Ｂ２は、水が入らないように密閉状態に形成されている。なお、空間Ｂ２は密閉状態にするのが望ましいが、必ずしもそうである必要はない。 The second chamber B is provided with a second partition plate 18 for dividing the internal space into two. Fixed contacts 51 and 52 constituting the contact mechanism 5 are attached to the partition plate 18 in an insulated state with a predetermined interval. A movable contact 50 constituting the contact mechanism 5 is disposed in one space B1 with the partition plate 18 in between. Further, the other space B2 is a space for leading and guiding the lead wires 3 and 30.
In the space B1, a water-permeable cutout 19 is formed at a position corresponding to the space B1 of the end plate 15 so that water can enter. On the other hand, the space B2 is formed in a sealed state so that water does not enter. Although it is desirable that the space B2 be sealed, it is not always necessary.

前記可動接点５０は、固定接点５１，５２に対向位置し、前記側板１２の内面に固定されたアクチュエータ５３に支持固定されている。前記アクチュエータ５３は水との接触により膨張するＰＶＡスポンジなどの材料をもって板状に形成されたものであり、その板状体の一表面に可動接点５０が接着されている。ＰＶＡスポンジは、微細な連続気孔構造をもち、親水性、吸収性、および保水性に優れている。このＰＶＡスポンジに代えて例えば水膨張ゴム発泡体を用いてもよい。水膨張ゴム発泡体は一般に天然ゴム、クロロプレンゴム、ウレタンゴムなどをベースとし、水膨張性を有するものである。可動接点５０はアクチュエータ５３の膨張時に固定接点５１，５２と接触する位置まで変位するように固定接点５１，５２との対向距離が設定されている。可動接点５０が固定接点５１，５２に接触したとき、固定接点５１，５２間が可動接点５０を介して導通する。なお、リード線を通す前記貫通孔１５ａや連通孔１７ａを水膨張ゴムを用いてシールすれば、第１の室Ａおよび第２の室Ｂの空間Ｂ２の防水性を高めることができる。   The movable contact 50 is opposed to the fixed contacts 51 and 52 and is supported and fixed to an actuator 53 fixed to the inner surface of the side plate 12. The actuator 53 is formed into a plate shape with a material such as PVA sponge that expands by contact with water, and a movable contact 50 is bonded to one surface of the plate-like body. PVA sponge has a fine continuous pore structure and is excellent in hydrophilicity, absorbability, and water retention. Instead of this PVA sponge, for example, a water expanded rubber foam may be used. The water-expandable rubber foam is generally based on natural rubber, chloroprene rubber, urethane rubber or the like and has water expandability. The distance between the movable contact 50 and the fixed contacts 51 and 52 is set so that the movable contact 50 is displaced to a position where it contacts the fixed contacts 51 and 52 when the actuator 53 is expanded. When the movable contact 50 comes into contact with the fixed contacts 51, 52, the fixed contacts 51, 52 are conducted through the movable contact 50. If the through hole 15a and the communication hole 17a through which the lead wire is passed are sealed with water expansion rubber, the waterproof property of the space B2 of the first chamber A and the second chamber B can be enhanced.

図４は、救難用点灯装置１の構成を電気回路として示したものである。同図において、４は乾電池、２は表示灯であり、この表示灯２の点灯回路６中に前記接点機構５が介装されている。接点機構５は、固定接点５１，５２と、固定接点５１，５２に対向配置される可動接点５０と、可動接点５０を支持し水との接触により膨張して可動接点５０を固定接点５１，５２と接触する位置まで変位させるアクチュエータ５３とを含んでいる。なお、前記点灯回路６は、前記したリード線３，３０〜３２に介して乾電池４、表示灯２、および接点機構５が接続されることにより構成されるものである。   FIG. 4 shows the configuration of the rescue lighting device 1 as an electric circuit. In the figure, 4 is a dry battery, 2 is an indicator lamp, and the contact mechanism 5 is interposed in the lighting circuit 6 of the indicator lamp 2. The contact mechanism 5 includes fixed contacts 51 and 52, a movable contact 50 disposed opposite to the fixed contacts 51 and 52, supports the movable contact 50, and expands by contact with water so that the movable contact 50 is fixed to the fixed contacts 51 and 52. And an actuator 53 that is displaced to a position in contact with the actuator 53. The lighting circuit 6 is configured by connecting the dry battery 4, the indicator lamp 2, and the contact mechanism 5 through the above-described lead wires 3, 30 to 32.

前記点灯回路６には、図５に示すような自己保持回路６０を設けてもよい。この自己保持回路６０は、前記接点機構５が閉動作して点灯回路６が通電したとき、その通電状態を保持する。図示例の自己保持回路６０は、リレー６１と常開のリレー接点６２とで構成されている。リレー接点６２は接点機構５と並列に接続してある。この実施例によれば、接点機構５が閉動作したとき、リレー６１が付勢されてリレー接点６２が閉じるので、その後、接点機構５が開動作や開閉動作を行っても点灯回路６の通電が安定した状態で保持される。   The lighting circuit 6 may be provided with a self-holding circuit 60 as shown in FIG. This self-holding circuit 60 holds the energized state when the contact mechanism 5 is closed and the lighting circuit 6 is energized. The self-holding circuit 60 in the illustrated example includes a relay 61 and a normally open relay contact 62. The relay contact 62 is connected in parallel with the contact mechanism 5. According to this embodiment, when the contact mechanism 5 is closed, the relay 61 is energized and the relay contact 62 is closed, so that the lighting circuit 6 is energized even if the contact mechanism 5 performs an opening operation or an opening / closing operation thereafter. Is held in a stable state.

上記した構成の救難用点灯装置が着水していない状態では、接点機構５の可動接点５０は固定接点５１，５２から離れて定位し、接点機構５は開いている。その結果、点灯回路６は通電せず、表示灯２は点灯しない。救難用点灯装置が着水すると、ケース１０の第２の室Ｂの空間Ｂ１に水が浸入するので、アクチュエータ５３は水と接触して膨張する。これにより、可動接点５０は固定接点５１，５２と接触する位置まで変位し、固定接点５１，５２間が可動接点５０を介して導通し、接点機構５が閉じる。その結果、点灯回路６は通電し、表示灯２が点灯する。なお、着水時、ケース１０の第１の室Ａには水が浸入せず、乾電池４が水に浸ることがないので、動作に支障をきたすおそれはない。   In the state where the rescue lighting device having the above-described configuration has not landed, the movable contact 50 of the contact mechanism 5 is positioned away from the fixed contacts 51 and 52, and the contact mechanism 5 is open. As a result, the lighting circuit 6 is not energized and the indicator lamp 2 is not lit. When the rescue lighting device lands, water enters the space B1 of the second chamber B of the case 10, so that the actuator 53 expands in contact with the water. Thereby, the movable contact 50 is displaced to a position where it comes into contact with the fixed contacts 51, 52, the fixed contacts 51, 52 are conducted through the movable contact 50, and the contact mechanism 5 is closed. As a result, the lighting circuit 6 is energized and the indicator lamp 2 is lit. In addition, since water does not permeate into the 1st chamber A of case 10 at the time of water landing, and the dry battery 4 does not soak in water, there is no possibility of causing trouble in operation.
