Description
【０００１】[0001]
本考案は、トラベル時計、ダイバー用腕時計等、暗所における時刻認知に利用 する自発光式の夜光塗料付時計に関するものである。 The present invention relates to a self-luminous watch with a luminous paint used for time recognition in a dark place, such as a travel watch and a diver's watch.
【０００２】[0002]
従来より、文字板または指針に夜光塗料が塗布されている夜光塗料付時計があ るが、この時計の前面カバーは単層のガラスであった。その前面カバーは、SiO2 ，Na2O,K20,Al2O3等を含有する単層ガラスが用いられ、それは、耐擦傷性向上に 主眼が置かれたものが多かった。夜光塗料から発生する放射線は、これらのガラ スによって完全に遮蔽されるが、自然放射線より極く低レベルの低エネルギ制動 Ｘ線は時計体外部へ放出され、これらの完全な遮蔽は困難であった。さらに、夜 光塗料中の放射性同位元素の単位面積当たりの密度を大きくすると、これら放射 線の漏洩が増大する傾向にあった。Conventionally, there is a watch with luminescent paint in which the luminescent paint is applied to the dial or pointer, but the front cover of this watch was made of single-layer glass. For the front cover, a single-layer glass containing SiO 2 , Na 2 O, K 2 0, Al 2 O 3, etc. was used, and most of them were focused on improving scratch resistance. Radiation generated from the luminescent paint is completely shielded by these glasses, but low-energy braking X-rays, which have a much lower level than natural radiation, are emitted to the outside of the watch body, and it is difficult to completely shield them. It was Furthermore, increasing the density of radioisotopes in the luminescent coating per unit area tended to increase the leakage of these radiation rays.
【０００３】[0003]
従来のデザインやさらに点状発光の夜光時計において、放射線保護に対して、 より安全性を高める商品設計をする場合、従来のガラスのみで制動Ｘ線を完全に 遮蔽しようとすると、ガラスの板厚が現在の寸法の数倍以上となり、時計全体の 厚みが厚くなり、見栄えも低下し、その結果、夜光塗料付時計の商品価値を低減 させてしまうものとなる。また、放出される制動Ｘ線の量を低減するために夜光 塗料中の放射性同位元素の量を少なくすると、発光輝度が低下し、夜光塗料の本 来の機能は発揮できなくなるという問題点を有していた。 When designing a product that enhances safety with respect to radiation protection in a conventional design or a point-light-emitting luminescent watch, if the conventional X-ray alone is used to completely block braking X-rays, the glass plate thickness Is more than several times the current size, the overall thickness of the watch becomes thicker, and the appearance is reduced, resulting in a reduction in the commercial value of the watch with luminescent coating. Further, if the amount of radioactive isotope in the luminous paint is reduced in order to reduce the amount of bremsstrahlung emitted, there is a problem in that the luminous brightness is reduced and the original function of the luminous paint cannot be exhibited. Was.
【０００４】 そこで本考案の目的は、発光輝度を低下させることなく、また、厚みを厚くす ることなく、夜光塗料から発生する低レベルの低エネルギ制動Ｘ線の時計からの 漏洩を防止することにある。Therefore, an object of the present invention is to prevent leakage of low-level low-energy braking X-rays generated from luminescent paint from a timepiece without lowering the emission brightness and increasing the thickness. It is in.
【０００５】[0005]
上記目的を達成するために、夜光塗料付時計において、本考案では、放射線、 特にはＸ線を遮蔽する成分を含んだ内側ガラスと、耐擦傷性の高い外側ガラスと からなる２重構造のカバーガラスが設けてある。 In order to achieve the above object, in a watch with a luminescent coating, the present invention has a double-layered cover including an inner glass containing a component that shields radiation, particularly X-rays, and an outer glass having high scratch resistance. Glass is provided.
【０００６】[0006]
以下、本考案の詳細を添付図面に示した実施例にそって説明する。 Hereinafter, the details of the present invention will be described with reference to the embodiments shown in the accompanying drawings.
【０００７】 図１は、本考案を適用した夜光塗料付腕時計の断面図であり、時計ケースは、 胴１と裏蓋２と前面カバー３とで構成されている。この時計ケースの内部には時 計機械体モジュール４が設けてあり、その前面に文字板が配設してある。時計機 械体モジュール４からは、図示しない指針軸が文字板５を貫通しており、その先 端に指針６が圧入されている。FIG. 1 is a cross-sectional view of a wristwatch with luminescent paint to which the present invention is applied, and a watch case includes a case 1, a back cover 2 and a front cover 3. A clock mechanism module 4 is provided inside the watch case, and a dial is arranged on the front surface thereof. From the timepiece machine module 4, a pointer shaft (not shown) penetrates the dial plate 5, and a pointer 6 is press-fitted at its tip.
【０００８】 文字板５の時刻目盛および指針６には、夜間等の暗所での時刻認知を可能とす るために夜光塗料（図示せず）が塗布されている。夜光塗料の一例としては、発 光物質として硫化亜鉛(ZnS）が、放射線発生物質として数十μキュリーの放射能 を有する147Pmが使用され、両者を適宜のバインダで混練したものを使用した。 この夜光塗料によれば、２次的に発生する制動Ｘ線エネルギは数十KeV〜百数十K eVである。The time scale of the dial 5 and the hands 6 are coated with a luminescent paint (not shown) to enable time recognition in a dark place such as at night. As an example of the luminous paint, zinc sulfide (ZnS) was used as a light emitting substance, and 147 Pm having a radioactivity of several tens μcurie was used as a radiation generating substance, and both were kneaded with an appropriate binder. According to this luminous paint, the braking X-ray energy generated secondarily is several tens KeV to hundreds of tens KeV.
【０００９】 前面カバー３は、内側ガラス３ａと外側ガラス３ｂの２重構造のものが採用さ れている。内側ガラス３ａは、Ｘ線遮蔽能力を有するものであって、Ｘ線を遮蔽 または吸収する能力のある Pb,Na,K等の重金属元素を含有しており、さらに具体 的には、SiO2:40〜45wt％,PbO:40〜45wt％,Na2O+K2O:5〜15％の組成のPbO系ガラ スが好適である。The front cover 3 has a double structure of an inner glass 3a and an outer glass 3b. The inner glass 3a has an X-ray shielding ability and contains a heavy metal element such as Pb, Na, K having an ability to shield or absorb X-rays, and more specifically, SiO 2 : PbO-based glass having a composition of 40 to 45 wt%, PbO: 40 to 45 wt%, Na 2 O + K 2 O: 5 to 15% is preferable.
【００１０】 一方、外側ガラス３ｂは、耐擦傷性の高いSiO2,Al2O3を主成分とする、いわゆ るサファイアガラスが使用されている。On the other hand, as the outer glass 3b, so-called sapphire glass containing SiO 2 and Al 2 O 3 having high scratch resistance as a main component is used.
【００１１】 内側ガラス３ａと外側ガラス３ｂは、この実施例では、紫外線硬化型等の適宜 の接着剤を用いて接合してあるが、必ずしも接合するする必要はなく、単に重ね 合わさった構造でも構わないことは言うまでもないことである。In this embodiment, the inner glass 3a and the outer glass 3b are bonded by using an appropriate adhesive such as an ultraviolet curing type, but they are not necessarily bonded and may be simply superposed structures. It goes without saying that there is nothing.
【００１２】 以上のような２重構造の前面カバー３によれば、夜光塗料の発生するＸ線は勿 論のこと、制動Ｘ線も１００％遮蔽することが確認された。It has been confirmed that, according to the double-structured front cover 3 as described above, not only the X-rays generated by the luminescent coating but also the braking X-rays are shielded by 100%.
【００１３】 また、サファイアガラスは、ビッカース硬さがHv1200〜1400で、PbO系ガラス （Hv350〜400）の数倍の硬度を持つため、本考案では、腕時計の実装着テストに おいて、擦傷性能をPbO単独ガラスに比べ、数倍〜十数倍に高めることができた 。In addition, sapphire glass has a Vickers hardness of Hv1200 to 1400, which is several times higher than that of PbO glass (Hv350 to 400). Could be increased several times to more than ten times compared to PbO single glass.
【００１４】 この実施例によれば、夜光塗料付時計は、前面カバーの擦傷性能を損なうこと なく、また、時計全体の厚みも従来レベルを維持して、Ｘ線の漏洩を防止するこ とができる。また、放射性同位元素の単位面積当たりの密度を大きくした場合に も同様の効果が認められた。According to this embodiment, the timepiece with the luminescent coating can prevent leakage of X-rays without impairing the scratching performance of the front cover and maintaining the thickness of the entire timepiece at the conventional level. it can. The same effect was also observed when the density of the radioisotope per unit area was increased.
【００１５】[0015]
本考案の構成によれば、夜光塗料付時計において、点状高輝度発光のデザイン が可能になり、また、夜光塗料から放射されるＸ線および制動Ｘ線の漏洩を商品 価値を損なうことなく防止することができる。 According to the configuration of the present invention, it is possible to design a dot-like high-intensity light emission in a timepiece with a luminescent coating, and prevent leakage of X-rays and braking X-rays radiated from the luminescent coating without impairing the commercial value. can do.
