以下、本発明を実施するための最良の形態について説明する。 Hereinafter, the best mode for carrying out the present invention will be described.
図１は本発明の防音保護具の実施形態を例示する要部正面図である。図２は図１に示す防音保護具に使用されている耳栓の断面図である。 FIG. 1 is a front view of an essential part illustrating an embodiment of a soundproof protector according to the present invention. FIG. 2 is a cross-sectional view of the earplug used in the soundproof protector shown in FIG.
この防音保護具１は、2つの耳栓２０（Ｌ）、２０（Ｒ）と、両耳栓２０（Ｌ）、２０（Ｒ）を互いに連結しているコード３０と、コード３０を巻き取り収納するコード収納装置４０と、を有する。 The soundproofing protective device 1 includes two earplugs 20 (L) and 20 (R), a cord 30 connecting both earplugs 20 (L) and 20 (R) to each other, and winding and storing the cord 30 A cord storage device 40.
両耳栓２０（Ｌ）、２０（Ｒ）は、構造も機能も全く同一の耳栓である。
耳栓２０は、外耳道に挿入される耳栓体２１と、耳栓体２１と一体化した連結具２２と、を有する。 Both earplugs 20 (L) and 20 (R) are earplugs having the same structure and function.
The earplug 20 includes an earplug body 21 that is inserted into the ear canal and a connector 22 that is integrated with the earplug body 21.
耳栓体２１は、形状復元性と柔軟性とを併せ持つ材料でできている。この種の材料として、ポリウレタンが知られている。耳栓２０は、耳栓体２１を指で摘んで細く潰した状態で、外耳道内に挿入することにより、外耳道に装着される。耳栓体２１がその自己復元性により元の状態（自由状態）に戻ろうとする過程で、その外周面が外耳道の内面に全周に亘って密着する。耳栓２０を装着することにより、装着者の外耳道内を外部からの騒音を遮断した静かな環境に保つことができる。耳栓２０の遮音値（ＮＲＲ）は１８ｄＢ以上、好ましくは２９ｄＢ以上である。 The earplug body 21 is made of a material having both shape restoring properties and flexibility. Polyurethane is known as this type of material. The earplug 20 is attached to the ear canal by being inserted into the ear canal while the earplug body 21 is pinched with a finger and crushed. In the process in which the earplug 21 returns to its original state (free state) due to its self-restoring property, the outer peripheral surface closely adheres to the inner surface of the ear canal over the entire periphery. By wearing the earplug 20, it is possible to keep the inside of the ear canal of the wearer in a quiet environment in which noise from the outside is blocked. The sound insulation value (NRR) of the earplug 20 is 18 dB or more, preferably 29 dB or more.
連結具２２は、耳栓体２１の反挿入側端部２１ａから内部に延在している埋没部２２Ａと、耳栓体２１の反挿入側端部２１ａから外部に延在している露出部２２Ｂと、を有する。 The connector 22 includes an embedded portion 22A extending from the anti-insertion side end portion 21a of the ear plug body 21 to the inside and an exposed portion extending from the anti-insertion side end portion 21a of the ear plug body 21 to the outside. 22B.
露出部２２Ｂは、コード３０の端部に連結されている。
連結具２２は、細い１本の紐２４からなる。
コード３０及び紐２４は、蛍光物質を含有した材料でできている。蛍光物質の例として、株式会社ネモト・ルミマテリアル製の高輝度長残光製蓄光顔料（Ｎ夜光（登録商標）、ルミノーバ（登録商標））を挙げることができる。
埋没部２２Ａは、紐２４の両端部２４ａ、２４ｂを平行に並べた状態で耳栓体２１の内部に埋没させることにより形成されている。紐２４の両端部２４ａ、２４ｂは、耳栓体２１の反挿入側端部２１ａの中央部に形成された挿入穴２１ｂに挿し込むとともに接着剤で固定されている。
露出部２２Ｂは、コード３０に連結された環状部２２Ｃを有する。
環状部２２Ｃは、紐２４が環状に湾曲した部分、この例では露出部２２Ｂ全体からなる。
環状部２２Ｃの周長は、１乃至１０ｃｍである。 The exposed portion 22B is connected to the end portion of the cord 30.
The connector 22 is composed of a single thin string 24.
The cord 30 and the string 24 are made of a material containing a fluorescent substance. As an example of a fluorescent substance, the high brightness long afterglow photoluminescent pigment (N nightlight (trademark), luminova (trademark)) made from Nemoto Lumi Material Co., Ltd. can be mentioned.
The buried portion 22A is formed by burying the ear plug body 21 in the state in which both end portions 24a and 24b of the string 24 are arranged in parallel. Both end portions 24a and 24b of the string 24 are inserted into an insertion hole 21b formed in the central portion of the anti-insertion side end portion 21a of the earplug 21 and fixed with an adhesive.
The exposed part 22 </ b> B has an annular part 22 </ b> C connected to the cord 30.
The annular portion 22C includes a portion where the string 24 is curved in an annular shape, in this example, the entire exposed portion 22B.
The circumferential length of the annular portion 22C is 1 to 10 cm.
コード３０の両端には、耳栓１を着脱可能に連結できるように、弾性部材からなるリングクリップ（連結対象）３１が設けられている。耳栓１は、その環状部２２Ｃをリングクリップ３１に係止させることにより、コード３０に着脱自在に連結されている。 At both ends of the cord 30, ring clips (connection objects) 31 made of an elastic member are provided so that the earplug 1 can be detachably connected. The earplug 1 is detachably connected to the cord 30 by locking the annular portion 22 </ b> C to the ring clip 31.
コード収納装置４０は、巻取機構４１と、巻取機構４１を収容した筐体４３と、を有する。巻取機構４１は、コード３０の中間部が巻回された巻取ドラム（図示省略）と、コード３０を巻き取る向きに巻取ドラムを回転させるべく巻取ドラムを常時付勢している付勢機構（図示省略）と、を有する。
巻取機構４１は、巻取ドラムが筐体４３に対して第１の向きに回転することによりコード３０を巻取ドラムに巻き取り、第２の向き（第１の向きの逆向き）に回転することにより、巻取ドラムからコード３０を繰り出すように構成されている。より詳細には、巻取ドラムに巻き取られているコード３０の両側を引っ張ると、付勢機構の力に抗して、巻取ドラムが筐体４３に対して第２の向きに回転し、コード３０が繰り出される。そして、コード３０が所定長（たとえば、左右に１０ｃｍずつ）繰り出される毎に、巻取機構４１内の係止機構（図示省略）により巻取ドラムが係止され、コード３０が繰り出された状態に保持される。この仕組みにより、コード３０の繰り出し長を段階的に調節することができる。再度コード３０の両側を少し引っ張ると、巻取ドラムの係止状態が解除される。そして、付勢機構の力で巻取ドラムが第１の向きに回転し、コード３０が巻き取られる。 The cord storage device 40 includes a winding mechanism 41 and a housing 43 that stores the winding mechanism 41. The winding mechanism 41 has a winding drum (not shown) around which the intermediate portion of the cord 30 is wound, and a winding drum that constantly biases the winding drum to rotate the winding drum in the direction in which the cord 30 is wound. Force mechanism (not shown).
The winding mechanism 41 winds the cord 30 around the winding drum when the winding drum rotates in the first direction with respect to the housing 43, and rotates in the second direction (opposite direction of the first direction). By doing so, the cord 30 is fed out from the winding drum. More specifically, when both sides of the cord 30 wound around the winding drum are pulled, the winding drum rotates in the second direction with respect to the housing 43 against the force of the urging mechanism, The code 30 is paid out. Each time the cord 30 is fed out by a predetermined length (for example, 10 cm to the left and right), the winding drum is locked by a locking mechanism (not shown) in the winding mechanism 41 so that the cord 30 is drawn out. Retained. With this mechanism, the feeding length of the cord 30 can be adjusted stepwise. When the both sides of the cord 30 are pulled a little again, the winding drum is unlocked. Then, the winding drum rotates in the first direction by the force of the urging mechanism, and the cord 30 is wound up.
コード収納装置４０には、これを着用者の衣服に着脱可能に取り付けるためのバチ型クリップ（挟持具）４４が設けられている。バチ型クリップ４４は、コード収納装置４０の筐体４３の外面に取り付けられている。 The cord storage device 40 is provided with a bee-type clip (clamping tool) 44 for detachably attaching it to the wearer's clothes. The bee-type clip 44 is attached to the outer surface of the housing 43 of the cord storage device 40.
この防音保護具１は、コード収納装置４０に設けられているバチ型クリップ４４で着用者の衣服の襟や胸ポケットなどを挟むことにより、着用者の衣服に取り付けることができる。コード３０の両端に耳栓２０が連結されているので、耳栓２０の紛失を防止できる。耳栓２０を使用しないときには、コード３０をコード収納装置４０内に巻き取って収納しておくことができ、耳栓２０を使用する際には、コード３０の両側を引っ張ることにより、簡単にコード３０を延ばすことができるので、携帯性、使い勝手が共に優れている。 The soundproofing protective device 1 can be attached to the wearer's clothes by sandwiching a collar or a breast pocket of the wearer's clothes with a bee-type clip 44 provided in the cord storage device 40. Since the earplugs 20 are connected to both ends of the cord 30, the earplugs 20 can be prevented from being lost. When the earplug 20 is not used, the cord 30 can be wound and stored in the cord storage device 40. When the earplug 20 is used, the cord 30 can be easily pulled by pulling both sides of the cord 30. Since 30 can be extended, both portability and usability are excellent.
また、使用により耳栓２０が汚れたときには、コード３０の先端のリングクリップ３１を開くことにより、簡単に、使用済み耳栓２０を取り外して、新しい耳栓２０に交換することができる。耳栓２０の環状部２２Ｃが細い紐２４でできていることにより、リングクリップ３１との係脱（掛け外し）を容易に行うことができる。 Further, when the earplug 20 becomes dirty due to use, the used earplug 20 can be easily removed and replaced with a new earplug 20 by opening the ring clip 31 at the tip of the cord 30. Since the annular portion 22C of the earplug 20 is made of a thin string 24, it can be easily engaged with and disengaged from (removed from) the ring clip 31.
また、耳栓２０の環状部２２Ｃの周長を６乃至１０ｃｍに選定しておけば、リングクリップ３１以外の連結対象との連結も容易である。たとえば、耳栓２０の環状部２２Ｃに連結対象であるコードや紐を直接結びつけることも可能である。すなわち、耳栓２０は、図１に示す防音保護具１の専用品ではない。耳栓２０をコードなどと接続せず単体で使用することも可能である。 Further, if the circumference of the annular portion 22C of the earplug 20 is selected to be 6 to 10 cm, it is easy to connect to a connection object other than the ring clip 31. For example, it is possible to directly tie a cord or string to be connected to the annular portion 22C of the earplug 20. That is, the earplug 20 is not a dedicated item for the soundproofing protector 1 shown in FIG. The earplug 20 can be used alone without being connected to a cord or the like.
耳栓２０を単体で使用する場合においても、紐２４でできた環状部２２Ｃが耳栓２０の反挿入側端部２０ａから外方に延びていることにより、その環状の部分に指を掛けたり、摘まんだりして、耳栓２０を外耳道から引き抜くことができるというメリットがある。 Even when the earplug 20 is used alone, the annular portion 22C made of the string 24 extends outward from the opposite end 20a of the earplug 20 so that the annular portion can be hooked with a finger. There is an advantage that the earplug 20 can be pulled out from the ear canal.
耳栓２０は、耳栓体２１の反挿入側端部２１ａの中央部に紐２４の両端部２４ａ、２４ｂを差し込むという単純な工程で製造できるので、安価に製造できる。 The earplug 20 can be manufactured at a low cost because it can be manufactured by a simple process of inserting both end portions 24a and 24b of the string 24 into the central portion of the end portion 21a opposite to the insertion side of the earplug body 21.
耳栓２０は、柔軟な耳栓体２１に柔軟な紐２４を一体化してなり、したがって全体が柔軟であるので、外耳道に安全に装着できる。また、耳栓体２１を細く潰して外耳道に挿入する際、耳栓体２１と紐２４とが共に柔軟に変形するため、紐２４の存在によって耳栓２０の装着性が損なわれることはない。
The earplug 20 is formed by integrating a flexible string 24 with a flexible earplug body 21, and is therefore flexible as a whole. Therefore, the earplug 20 can be safely attached to the ear canal. Further, when the earplug 21 is crushed and inserted into the external auditory canal, both the earplug 21 and the string 24 are flexibly deformed, so that the wearability of the earplug 20 is not impaired by the presence of the string 24.
また、耳栓２０を所定個数単位で保管又は流通させる際、当該所定個数分の耳栓２０の環状部２２Ｃを紐などで結束することにより、耳栓２０を当該所定個数単位で取り扱うことができる。また、耳栓２０を数個乃至１０数個単位で取り扱う場合であれば、そのうちの１個の耳栓２０の環状部２２Ｃを結束用の紐として利用することができる。たとえば、耳栓２０を１０個単位で取り扱う場合、そのうちの１個の耳栓２０の環状部２２Ｃで残りの９個の耳栓２０の環状部２２Ｃを結束することができる。 Further, when the earplugs 20 are stored or distributed in a predetermined number unit, the earplugs 20 can be handled in the predetermined number unit by binding the ring portions 22C of the predetermined number of earplugs 20 with a string or the like. . If the earplug 20 is handled in units of several to ten, the annular portion 22C of one of the earplugs 20 can be used as a binding string. For example, when the earplugs 20 are handled in units of ten, the annular portions 22C of the remaining nine earplugs 20 can be bound by the annular portions 22C of one earplug 20 of them.
また、耳栓体２１の反挿入側端部２１ａから外部に延びている紐２４が蛍光物質を含有した材料でできていることにより、工場などにおける安全衛生管理責任者は、騒音環境で作業に従事している者が耳栓２０を装着しているか否かを暗所においても容易に視認できる。また、左右の耳栓２０を連結しているコード３０が蛍光物質を含有した材料でできていることにより、防音保護具１の位置や使用状態を暗所においても容易に視認できる。 In addition, since the string 24 extending outward from the end 21a of the earplug 21 to the outside is made of a material containing a fluorescent substance, the person in charge of safety and health management in a factory can work in a noisy environment. Whether or not the person engaged is wearing the earplug 20 can be easily visually recognized even in a dark place. Further, since the cord 30 connecting the left and right earplugs 20 is made of a material containing a fluorescent material, the position and use state of the soundproofing protective device 1 can be easily visually recognized even in a dark place.
