本考案は、腕時計本体とバンドとを接続するための腕時
計用係止棒に係り、特に腕時計本体とバンドとの不必要
な分離を防止するのに好適な腕時計用係止棒に関する。[Detailed Description of the Invention] The present invention relates to a wristwatch locking rod for connecting a wristwatch body and a band, and particularly to a wristwatch locking rod suitable for preventing unnecessary separation between the wristwatch body and the band. Regarding the stop bar.
第１図は従来の腕時計用係止棒、すなわちばね棒を示す
もので、以下これについて説明すると、１は、バンド（
図示せず）端部に挿入される管体であり、この管体１内
には、止片２，３および両止片２，３を外方に付勢する
コイルスプリング４がそれぞれ配置されている。FIG. 1 shows a conventional watch locking rod, that is, a spring rod.This will be explained below.
(not shown) is a tube body inserted into the end portion, and inside this tube body 1, stop pieces 2, 3 and coil springs 4 for urging both stop pieces 2, 3 outward are arranged respectively. There is.
そして、両止片２，３は管体１両端部の絞り部１ａで抜
は止めされている。Both retaining pieces 2 and 3 are prevented from being pulled out by constricted portions 1a at both ends of the tube body 1.
一方の止片２の外面側には、中間に２枚の離脱鍔５，５
を有する係止片６が設けられ、また他方の止片３の外面
側には短い係止片７が設けられている。On the outer surface side of one stopper piece 2, there are two detachable collars 5, 5 in the middle.
A locking piece 6 having a diameter is provided, and a short locking piece 7 is provided on the outer surface of the other locking piece 3.
そして、両係止片６，７は、腕時計本体８に対向して設
けられた保合穴９，１０にそれぞれ係合されるようにな
っている。Both locking pieces 6 and 7 are adapted to be engaged with retaining holes 9 and 10 provided oppositely in the wristwatch main body 8, respectively.
このように構成されたばね棒は、離脱鍔５，５をコイル
スプリング４の付勢力に抗して内側に押圧することによ
り腕時計本体８から取外すことができるようになってい
る。The spring bar constructed in this manner can be removed from the wristwatch main body 8 by pressing the detachable collars 5, 5 inward against the biasing force of the coil spring 4.
以上の構成を有する従来のばね棒において、その着脱の
使用態様をみてみると、腕時計の購入時に各自の希望に
より時計本体とバンドとを選定して組合わせる場合、あ
るいは各自の好みに応じてバンドを交換する場合等着脱
頻度は極めて少なく、はとんどの場合は一度取付ければ
二度と着脱しないのが通例である。Looking at how the conventional spring bar with the above structure is used for attaching and detaching it, it is possible to select and combine the watch body and the band according to the individual's wishes at the time of purchasing a watch, or to combine the watch body and the band according to the individual's preference. The frequency of attaching and detaching is extremely low, such as when replacing a device, and in most cases, once it is attached, it is customary to never attach or detach it again.
ところが、従来のばね棒は、前記するように係止片をコ
イルスプリングの付勢力により腕時計本体の係合穴に係
止する構造となっているため、満員電車内等でコイルス
プリングの付勢力以上の抗力が加わると、腕時計本体と
バンドとが分離してしまうという難点がある。However, as mentioned above, conventional spring bars have a structure in which the locking piece is locked into the engagement hole of the watch body by the biasing force of the coil spring, so in a crowded train, etc. The problem is that when drag is applied, the watch body and band separate.
また、従来のばね棒では、装着の際の便宜を考慮して一

時計本体とバンドとの分離をさらに助長している。In addition, in conventional spring bars, one of the locking pieces is provided with a detachable flange for convenience when mounting, making it easier to hook, but the tube body is made shorter by the amount of the detachable flange. Therefore, the supporting force of the locking piece decreases, making the locking piece more likely to bend, further promoting separation between the watch body and the band.
本考案はかかる従来の問題点を解決するためになされた
もので、その目的とするところは、不必要時に腕時計本
体とバンドとが分離するおそれがない腕時計用係止棒を
提供するにある。The present invention has been made to solve these conventional problems, and its purpose is to provide a locking rod for a wristwatch that is free from the risk of separating the wristwatch body and the band when unnecessary.
本考案は、少なくとも係止片を腕時計の保合穴に係脱さ
せるために伸縮力を与える部分に、形状記憶金属を用い
たものである。The present invention uses shape-memory metal at least in the portion that applies an elastic force to engage and disengage the locking piece from the retaining hole of the wristwatch.
本出願人は、係止棒の使用態様について詳細に検討した
結果、たとえ着脱時に多少面倒な操作を必要とするもの
であっても、通常時には絶対外れることがないものの方
が好ましいという結論を得た。As a result of a detailed study of the manner in which the locking rod is used, the applicant concluded that it is preferable to use a locking rod that will never come off under normal circumstances, even if it requires some troublesome operations when attaching and detaching. Ta.
そこで、本出願人はかかる要求を満足する機械的方法を
検討したが、構造が複雑になって故障が生じ易くなった
り、あるいは構造が複雑なわりには外れ易かったりして
、満足なものが得られながった。Therefore, the applicant considered a mechanical method to satisfy such requirements, but the structure was complicated and it was easy to break down, or the structure was complicated and could easily come off, so no satisfactory method could be obtained. I missed it.
このため、根本的に発想を変えて再度検討した結果、係
止棒の伸縮を必要とする個所に形状記憶金属を使用する
ことに思い至った。For this reason, we fundamentally changed our thinking and reconsidered, and as a result, we came up with the idea of using shape memory metal in the parts where the locking rod needs to expand and contract.
ところで、形状記憶金属とは、素材を変形させた後加熱
すると変形前の形状に素材が戻る、すなわち元の形状を
記憶している金属の総称であり、Ｔ１Ｎｉ、Ｃｕ３Ａ
ｌ 、ＣｕＡ Ｉ Ｎｉ、ＡｕＣｄ、Ｆｅ５Ｐｔ、Ｉｎ
Ｔ ｌその他の合金に現われる現象である。By the way, shape memory metal is a general term for metals that when heated after being deformed, the material returns to the shape before deformation, that is, it remembers its original shape.
l, CuA I Ni, AuCd, Fe5Pt, In
This is a phenomenon that appears in Tl and other alloys.
このような形状記憶の原因は、今日マルテンサイト変態
の現象として一般に理解されている。The cause of such shape memory is now generally understood as the phenomenon of martensitic transformation.
これは、温度が低下するにつれてマルテンサイトが連続
的に成長するとともに、逆に温度が上昇すると収縮し、
これらが可逆的に移行し得る熱弾性形マルテンサイト変
態と称する変態によるもので、温度低下あるいは応力に
よって発生、成長した双晶変形からなるマルテンサイト
は、加熱によって母相との整合性がよいことから逆変態
により母相中に吸収、消滅してしまう。This is because martensite grows continuously as the temperature decreases, and conversely contracts as the temperature increases.
This is due to a transformation called thermoelastic martensitic transformation that can be reversibly transferred, and martensite, which is formed by twin deformation that is generated and grown due to temperature drop or stress, has good consistency with the parent phase when heated. It is absorbed into the matrix and disappears due to reverse metamorphosis.
すなわち、低い温度で変形していた原因が加熱によって
消滅してしまうため元の形状に復元することになり、こ
れが記憶性の原因と考えられている。In other words, the cause of the deformation at low temperatures is eliminated by heating, so the original shape is restored, and this is thought to be the cause of the memorability.
したがって、基本的には以上の如き機構によって理解で
き、双晶変形による熱弾性形マルテンサイト変態を生じ
る組成、熱処理条件を探すことにより、各種金属の組合
わせが見出し得る。Therefore, the above mechanism can be basically understood, and combinations of various metals can be found by searching for compositions and heat treatment conditions that cause thermoelastic martensitic transformation due to twin deformation.
