【考案の詳細な説明】
この考案は携帯用腕時計で、特に軟質材を用いた防水用
側構造に関するものである。[Detailed Description of the Invention] This invention relates to a portable wristwatch, and particularly to a waterproof side structure using a soft material.
従来の軟質材を使用した防水構造は、第1図に示すよう
に、胴1の内周部下段にネジ部1aを設け、且つ胴1の
下段部にパツキン2の接触面を円周上に挽き込み、裏ブ
タ3には、上面外周部3aにネジ部を設けである。As shown in Fig. 1, a conventional waterproof structure using a soft material has a threaded portion 1a provided at the lower part of the inner circumference of the body 1, and a contact surface of the packing 2 on the lower part of the body 1 on the circumference. The back lid 3 is provided with a threaded portion on the outer peripheral portion 3a of the upper surface.
裏ブタ3を胴1にネジ込みすることによりパツキン2は
、胴1と裏ブタ3のボックス内にて、締代を持ち防水性
を保っている。By screwing the back cover 3 into the body 1, the packing 2 has a tightening margin within the box of the body 1 and the back cover 3, and maintains waterproofness.
軟質材、特にアルミニウム材質外装における場合、外装
の表面上に喰付部等があると、耐食性、喰付部の劣化、
等の品質が通常の腕時計の品質を満足し得ないため、第
1図に示す構造が主流であった。When using a soft material, especially an aluminum exterior, if there are any bites on the surface of the exterior, corrosion resistance may deteriorate, the bites may deteriorate,
Since the quality of these wristwatches did not satisfy that of ordinary wristwatches, the structure shown in Figure 1 was the mainstream.
又プラスチック等の高分子材料を使用する場合において
も使用されていた。It was also used when using polymeric materials such as plastics.
しかしこのような構造では、まず第1に裏ブタ3のネジ
幅及び胴1のネジ幅3b及びパッキンボクス幅3cが、
必要のため、どうしても領外径が大きくなる欠点があっ
た。However, in such a structure, first of all, the thread width of the back lid 3, the thread width 3b of the body 1, and the packing box width 3c are
Due to necessity, there was a drawback that the outer diameter of the area inevitably became large.
又プラスチック等の高分子材料を使用する場合、強度上
の問題から径もさることながら、ネジピッチも大きくな
ければいけないため、高す関係も厚くせざるを得ない欠
点があった。Furthermore, when using a polymeric material such as plastic, there is a drawback that not only the diameter but also the screw pitch must be large due to strength issues, and the height must also be thick.
第2に、最近はクォーツの普及で電池が裏ブタ方向につ
き、消費者、小売店等で電池を取り替える時、裏ブタ3
を外さなければならない。Secondly, with the recent spread of quartz, the battery is placed in the direction of the back cover, so when consumers or retailers change the battery, the back cover
must be removed.
電池ブタを取り付けるにも電池の平面位置がケース中心
でないと、裏ブタ3が回転するため電池ブタを取り付け
ることが不可能である。Even when attaching the battery cover, if the planar position of the battery is not at the center of the case, the back cover 3 will rotate, making it impossible to attach the battery cover.
且つ最近の腕時計の薄型化にきて電池を中心に位置する
ことは相反し難しい欠点がある。In addition, as wristwatches have become thinner in recent years, placing the battery at the center has the disadvantage of being contradictory and difficult.
この考案は上記欠点を除去するために、ネジによる胴と
裏ブタの固定をやめ、喰付固定にすることにより、外径
の径小化、デザイン性の向上、電池位置に左右されずに
電池ブタ取付可能にし、且つ品質の安定を目的としたも
のである。In order to eliminate the above-mentioned drawbacks, this invention eliminates the fixation of the body and back cover with screws and instead fixes them with bites, thereby reducing the outer diameter, improving design, and eliminating the need for batteries regardless of the battery position. The purpose is to enable pig attachment and to stabilize quality.
以下第2図により詳細に説明する。This will be explained in detail with reference to FIG. 2 below.
第2図はこの考案の断面図であって、この図において胴
1の内周部に中枠4を圧入もしくはネジ込みで固定する
。FIG. 2 is a sectional view of this invention, and in this figure, the inner frame 4 is fixed to the inner circumference of the shell 1 by press-fitting or screwing.
裏ブタ3の内周部に中子3dをロー付にて固定する。The core 3d is fixed to the inner circumference of the back cover 3 with brazing.
且つ中枠4の下段内周部4aには環状の溝として挽き込
みが形成され、又中子3dの外周上面部には、前記環状
溝と係合する環状突起3eが形成されている。In addition, an annular groove is formed in the lower inner periphery 4a of the middle frame 4, and an annular protrusion 3e that engages with the annular groove is formed on the upper surface of the outer periphery of the core 3d.
この考案は上述のような構造になっており、組立てる際
は胴1の段部1bにパツキン2を載せ裏ブタ3に圧力を
くわえることにより、中枠4の下段内周部4aと中子3
dの外周上面部3eが噴材く。This device has the above-mentioned structure, and when assembling, the packing 2 is placed on the stepped portion 1b of the body 1 and pressure is applied to the back cover 3, so that the lower inner peripheral portion 4a of the middle frame 4 and the core 3 are assembled.
The outer periphery upper surface portion 3e of d is exposed to the injection material.
且つパツキン2は胴1の段部1b及び裏ブタ3の上面3
fのボックス内で締代を持ち防水性を保持している。In addition, the packing 2 is attached to the stepped portion 1b of the body 1 and the upper surface 3 of the back lid 3.
It has a tightness within the box f and maintains waterproofness.
以上述べたように、この考案は胴1が軟宣材を使用した
際に生じる欠点を除去するべく以下の効果を有する。As described above, this invention has the following effects in order to eliminate the drawbacks that occur when the body 1 is made of soft material.
まず第1に噴材により胴1と裏ブタ3を固定するため電
池位置にかかわらず電池ブタを取り付けることが可能で
ある。First of all, since the shell 1 and the back cover 3 are fixed with the injection material, it is possible to attach the battery cover regardless of the battery position.
第2に側内部に噴材部をもってきたため、品質も向上す
る。Secondly, quality is also improved because the injection material part is placed inside the side.
第3に裏ブタ3の外径は従来のネジ結合に比べ径小化が
可能である。Thirdly, the outer diameter of the back cover 3 can be reduced compared to conventional screw connections.
カムに裏ブタの外観、デザインのまとまり具合が向上す
る(裏ブタにスパナ溝3gが無い。The appearance of the back cover on the cam and the cohesiveness of the design are improved (there is no spanner groove 3g on the back cover).
裏ブタ高す3hを高くすることにより胴を薄くできる。By increasing the back cover height 3h, the body can be made thinner.
)等の効果を有する。) and other effects.
