Description

この発明は、腕時計ケースに関する。   The present invention relates to a watch case.

従来、腕時計ケースにおいては、特許文献1に記載されているように、腕時計ケース本体の外表面に弾性部材を被覆すると共に、腕時計ケース本体の側面部に設けられた押釦の周辺に位置する弾性部材を外側に向けて出っ張る形状に形成し、衝撃が押釦に直接加わらず、押釦の周辺に位置する弾性部材の出っ張り部分に加わることにより、押釦の破損を防ぎ、且つ押釦を通じて伝わる衝撃により腕時計ケース本体内の時計モジュールが破壊されるのを防ぐように構成されたものが知られている。   Conventionally, in a watch case, as described in Patent Document 1, an elastic member is coated on the outer surface of the watch case main body and is located around a push button provided on a side surface of the watch case main body. The watch case main body is formed in a shape that protrudes outward, and the impact is not directly applied to the push button, but is applied to the protruding portion of the elastic member located around the push button, thereby preventing the push button from being damaged and the impact transmitted through the push button. There are known ones configured to prevent destruction of the internal clock module.

実公昭63−44784Jiko-sho 63-44784

しかしながら、このような従来の腕時計ケースでは、デザインの形状によって弾性部材の肉厚が偏り、肉厚の薄い薄肉部が生じ、この薄肉部での弾性性能が低下し、十分に衝撃を吸収することができず、衝撃が腕時計ケース本体内に伝わり、内部の時計モジュールが機能障害を引き起こすことがあるという問題がある。   However, in such a conventional watch case, the thickness of the elastic member is uneven depending on the shape of the design, resulting in a thin part with a thin thickness, the elastic performance at this thin part is reduced, and the shock is sufficiently absorbed. However, there is a problem that the impact is transmitted to the inside of the wristwatch case body and the internal clock module may cause a malfunction.

また、腕時計ケース本体の外周に弾性部材を装着して固定する際、弾性部材が細長い枠形状である場合には、1時側と7時側、および5時側と11時側との各対角線上の箇所をねじで固定するほかに、3時側と9時側との対角線上の箇所も、ねじで固定する必要がある。このような場合には、3時側と9時側とが側面衝撃を受けやすいため、この部分を硬い塊状に形成して強度を確保しているが、衝撃吸収性が低く、衝撃が腕時計ケース本体の内部に伝わりやすい傾向がある。   In addition, when the elastic member is attached to the outer periphery of the wristwatch case main body and fixed in an elongated frame shape, the diagonal lines of the 1 o'clock side and the 7 o'clock side, and the 5 o'clock side and the 11 o'clock side are provided. In addition to fixing the upper part with a screw, it is also necessary to fix the part on the diagonal line between the 3 o'clock side and the 9 o'clock side with a screw. In such a case, the 3 o'clock side and the 9 o'clock side are susceptible to side impact, so this part is formed into a hard lump to ensure strength, but the impact absorption is low and the impact is watch case There is a tendency to be easily transmitted to the inside of the main body.

この発明が解決しようとする課題は、耐衝撃吸収性を確保することができる腕時計ケースを提供することである。   The problem to be solved by the present invention is to provide a wristwatch case that can ensure shock absorption.

本発明は、腕時計ケース本体の外表面を弾性カバー部材で被覆した腕時計ケースにおいて、前記弾性カバー部材は、所定の側面が外側に突出して形成されており、前記所定の側面の前記弾性カバー部材とこれに対応する前記腕時計ケース本体との間には、空間部が設けられ、前記所定の側面には、ねじ部材の頭部を挿入する挿入穴とねじ部材の首部を挿入する貫通孔とが設けられ、ねじ部材を前記挿入穴と前記貫通孔に挿入して前記腕時計ケース本体のねじ孔に螺着することで、前記弾性カバー部材が前記腕時計ケース本体に対して前記ねじ部材により固定されていることを特徴とする腕時計ケースである。

The present invention provides a watch case coated with the outer surface of the wristwatch case body with elastic cover member, the elastic cover member, the predetermined side is formed to protrude outwardly, and the resilient cover member of said predetermined side A space portion is provided between the watch case body corresponding thereto, and an insertion hole for inserting the head portion of the screw member and a through hole for inserting the neck portion of the screw member are provided on the predetermined side surface. The elastic cover member is fixed to the watch case main body by the screw member by inserting the screw member into the insertion hole and the through hole and screwing the screw member into the screw hole of the watch case main body. This is a watch case characterized by that.

この発明によれば、衝撃を吸収して衝撃が腕時計ケース本体に伝わるのを軽減することができるので、耐衝撃吸収性を確保することができる。   According to the present invention, it is possible to reduce the impact that is absorbed and transmitted to the wristwatch case main body, and therefore it is possible to ensure shock absorption.

以下、図1〜図7を参照して、この発明を腕時計に適用した一実施形態について説明する。
この腕時計は、図1〜図3に示すように、腕時計ケース1を備えている。この腕時計ケース1の上側開口部には、時計ガラス2がパッキン2aを介して取り付けられており、この腕時計ケース1の下部には、裏蓋3が防水リング3aを介してビス3bによって取り付けられている。
Hereinafter, an embodiment in which the present invention is applied to a wristwatch will be described with reference to FIGS.
The wristwatch includes a wristwatch case 1 as shown in FIGS. A watch glass 2 is attached to the upper opening of the watch case 1 via a packing 2a, and a back cover 3 is attached to the lower portion of the watch case 1 by a screw 3b via a waterproof ring 3a. Yes.

また、この腕時計ケース1の内部には、図3に示すように、時計モジュール4が収納されている。この場合、時計モジュール4の上面には、文字板4aが設けられており、この文字板4aと時計ガラス2の間には、見切部材4bが配置されている。また、時計モジュール4の下面と裏蓋3との間には、ゴムなどの緩衝部材4cが配置されている。さらに、この腕時計ケース1の側面には、図1に示すように、複数の押釦5が3時側と9時側とにそれぞれ2つずつ設けられているほか、6時側に位置する腕時計ケース1の上面にも、上面スイッチ6が設けられている。   In addition, a watch module 4 is accommodated in the wristwatch case 1 as shown in FIG. In this case, a dial plate 4 a is provided on the upper surface of the timepiece module 4, and a parting member 4 b is disposed between the dial plate 4 a and the timepiece glass 2. Further, between the lower surface of the timepiece module 4 and the back cover 3, a buffer member 4c such as rubber is disposed. Further, as shown in FIG. 1, a plurality of push buttons 5 are provided on the side surface of the wristwatch case 1 at two o'clock and nine o'clock, respectively, and the wristwatch case located at the six o'clock side. An upper surface switch 6 is also provided on the upper surface of 1.

また、この腕時計ケース1は、図1〜図4に示すように、腕時計ケース本体7と、この腕時計ケース本体7の上部外周に設けられた金属製のベゼル8と、このベゼル8の上面を除く外周面および腕時計ケース本体7の外周面を覆って設けられた弾性カバー部材9とを備えている。この場合、腕時計ケース本体7は、ポリアリレート(PAR)などの合成樹脂からなり、その上部には、図3に示すように、金属製の補強部材7aが埋め込まれている。   1 to 4, this watch case 1 excludes the watch case body 7, the metal bezel 8 provided on the upper outer periphery of the watch case body 7, and the upper surface of the bezel 8. And an elastic cover member 9 provided so as to cover the outer peripheral surface and the outer peripheral surface of the watch case main body 7. In this case, the wristwatch case body 7 is made of a synthetic resin such as polyarylate (PAR), and a metal reinforcing member 7a is embedded in the upper part thereof as shown in FIG.

金属製のベゼル8は、図1〜図3に示すように、ほぼ枠状に形成され、腕時計ケース本体7の上面および上部側面を覆って配置されるように構成されている。また、このベゼル8は、その外周下端部が時計ガラス2の下面の下に位置し、且つ時計モジュール4の上面よりも上に位置し、この外周の下端部にフック部8aが設けられている。弾性カバー部材9は、熱可塑性ポリウレタンエラストマ(TPU)などの弾性材料からなり、図1〜図4に示すように、腕時計ケース本体7の外周面を覆うほぼ枠状に形成され、ベゼル8の上面を除く外周面および腕時計ケース本体7の外周面を覆うように構成されている。   As shown in FIGS. 1 to 3, the metal bezel 8 is formed in a substantially frame shape, and is configured to cover the upper surface and upper side surface of the watch case body 7. Further, the lower end of the outer periphery of the bezel 8 is located below the lower surface of the watch glass 2 and above the upper surface of the watch module 4, and a hook portion 8a is provided at the lower end of the outer periphery. . The elastic cover member 9 is made of an elastic material such as thermoplastic polyurethane elastomer (TPU), and is formed in a substantially frame shape covering the outer peripheral surface of the watch case main body 7 as shown in FIGS. And the outer peripheral surface of the watch case body 7 are covered.

また、この弾性カバー部材9は、図1および図2に示すように、1時側と7時側、および5時側と11時側との各対角線上の箇所がビス10によって腕時計ケース本体7に固定されているほかに、3時側と9時側との対角線上の箇所も、ビス11によって腕時計ケース本体7に固定されている。この場合、弾性カバー部材9は、図1〜図3に示すように、3時側と9時側とに位置する側面が押釦5よりも外側に突出して形成されている。   Further, as shown in FIGS. 1 and 2, the elastic cover member 9 has a watch case main body 7 with screws 10 at diagonal positions of the 1 o'clock side and the 7 o'clock side, and the 5 o'clock side and the 11 o'clock side. In addition to being fixed to the watch case, the diagonal line between the 3 o'clock side and the 9 o'clock side is also fixed to the watch case body 7 by screws 11. In this case, as shown in FIGS. 1 to 3, the elastic cover member 9 is formed so that side surfaces located at the 3 o'clock side and the 9 o'clock side protrude outward from the push button 5.

すなわち、押釦5の周辺に位置する弾性カバー部材9の箇所のうち、中央部12は、図1および図4に示すように、3時側の押釦5の間と9時側の押釦5の間とに位置し、最も外側に突出して形成されている。また、この中央部12から押釦5を挟んで反対側の箇所に位置する周側部13は、押釦5の外面とほぼ同じ高さで、中央部12よりも低く形成されている。   That is, among the locations of the elastic cover member 9 located around the push button 5, the central portion 12 is between the push button 5 on the 3 o'clock side and the push button 5 on the 9 o'clock side, as shown in FIGS. And is formed to protrude to the outermost side. Further, the peripheral side portion 13 located on the opposite side of the push button 5 from the central portion 12 is formed to be substantially the same height as the outer surface of the push button 5 and lower than the central portion 12.

これにより、弾性カバー部材9は、図5および図7に示すように、腕時計ケース1が落下して腕時計ケース1の外周面が床などの平面Sに当接した際、弾性カバー部材9の中央部12および周側部13が床などの平面Sに当接しても、押釦5が床などの平面Sに接触しないように構成されている。   Thereby, as shown in FIGS. 5 and 7, when the wristwatch case 1 falls and the outer peripheral surface of the wristwatch case 1 comes into contact with a plane S such as a floor, the elastic cover member 9 Even if the portion 12 and the peripheral side portion 13 are in contact with a plane S such as a floor, the push button 5 is configured not to contact the plane S such as a floor.

例えば、図5に示すように、腕時計ケース1における弾性カバー部材9の中央部12が床などの平面Sにほぼ平行に当接した際には、弾性カバー部材9の中央部12のみが床などの平面Sに当接する。また、図7に示すように、腕時計ケース1における弾性カバー部材9の中央部12が床などの平面Sに傾いて当接した際には、弾性カバー部材9の中央部12とその周辺部13とが床などの平面Sに当接する。   For example, as shown in FIG. 5, when the central portion 12 of the elastic cover member 9 in the watch case 1 abuts substantially parallel to the plane S such as the floor, only the central portion 12 of the elastic cover member 9 is the floor or the like. It abuts on the plane S. As shown in FIG. 7, when the central portion 12 of the elastic cover member 9 in the watch case 1 is inclined and abuts against a plane S such as a floor, the central portion 12 of the elastic cover member 9 and the peripheral portion 13 thereof. And abut against a plane S such as a floor.

ところで、この弾性カバー部材9の中央部12には、図3および図4に示すように、ビス11が挿入する挿入孔部14が設けられている。この場合、ビス11は、頭部11a、首部11b、ねじ部11cを有し、先端側のねじ部11cが首部11bよりも少し細く形成されている。これに伴って、挿入孔部14には、ビス11の頭部11aが挿入する頭部挿入穴14aと、ビス11の首部11bが挿入する貫通孔14bとが設けられている。   By the way, as shown in FIGS. 3 and 4, an insertion hole portion 14 into which the screw 11 is inserted is provided in the central portion 12 of the elastic cover member 9. In this case, the screw 11 has a head portion 11a, a neck portion 11b, and a screw portion 11c, and the screw portion 11c on the distal end side is formed slightly narrower than the neck portion 11b. Accordingly, the insertion hole portion 14 is provided with a head insertion hole 14a into which the head portion 11a of the screw 11 is inserted and a through hole 14b into which the neck portion 11b of the screw 11 is inserted.

これにより、ビス11は、先端側のねじ部11cが弾性カバー部材9の挿入孔部14を通して腕時計ケース本体7に設けられたねじ孔15に螺着すると、図3および図4に示すように、頭部11aが頭部挿入穴14a内に沈み込んで、頭部挿入穴14aの底部に当接し、首部11bが貫通孔14bを通してその先端が腕時計ケース本体7の外周面に当接し、この状態で弾性カバー部材9を腕時計ケース本体7に対して固定するように構成されている。   As a result, when the screw 11 is screwed into the screw hole 15 provided in the wristwatch case body 7 through the insertion hole 14 of the elastic cover member 9 as shown in FIGS. The head 11a sinks into the head insertion hole 14a, contacts the bottom of the head insertion hole 14a, the neck 11b passes through the through hole 14b, and the tip contacts the outer peripheral surface of the watch case body 7, in this state. The elastic cover member 9 is configured to be fixed to the watch case body 7.

この場合、外側に突出した中央部12に位置する弾性カバー部材9とこれに対応する腕時計ケース本体7との間には、図3および図4に示すように、空間部16が設けられている。この空間部16は、弾性カバー部材9の内面に凹部を形成することにより、中央部12に位置する弾性カバー部材9とこれに対応する腕時計ケース本体7との間に設けられている。   In this case, as shown in FIGS. 3 and 4, a space 16 is provided between the elastic cover member 9 positioned at the center portion 12 protruding outward and the watch case body 7 corresponding thereto. . The space portion 16 is provided between the elastic cover member 9 located in the central portion 12 and the wristwatch case body 7 corresponding thereto by forming a recess in the inner surface of the elastic cover member 9.

すなわち、この空間部16は、図3に示すように、その厚みがビス11の首部11bの長さよりも少し短く、且つ腕時計ケース本体7の外周面における上下方向の広さがベゼル8の下部から腕時計ケース本体7の下端部付近(つまり、裏蓋3の周辺に対応する腕時計ケース本体7の下部外周)に亘って設けられているほか、腕時計ケース本体7の外周面に沿う方向の広さが、図4に示すように、3時側および9時側の各押釦5間に位置する広さで設けられている。   That is, as shown in FIG. 3, the space portion 16 has a thickness slightly shorter than the length of the neck portion 11 b of the screw 11, and the vertical width on the outer peripheral surface of the watch case body 7 extends from the lower portion of the bezel 8. In addition to being provided over the vicinity of the lower end of the watch case main body 7 (that is, the lower outer periphery of the watch case main body 7 corresponding to the periphery of the back cover 3), the width in the direction along the outer peripheral surface of the watch case main body 7 is As shown in FIG. 4, it is provided in a size located between the push buttons 5 on the 3 o'clock side and 9 o'clock side.

このような腕時計ケース1によれば、腕時計ケース本体7の外表面を被覆する弾性カバー部材9が、3時側と9時側との各側面の中央部12が外側に向けて突出して形成されており、その中央部12に位置する弾性カバー部材9とこれに対応する腕時計ケース本体7との間に、弾性カバー部材9が変形したときに、その弾性カバー部材9の変形した一部が挿入する空間部16が設けられていることにより、耐衝撃吸収性の高いものを得ることができる。   According to such a watch case 1, the elastic cover member 9 that covers the outer surface of the watch case body 7 is formed such that the central portions 12 of the side surfaces of the 3 o'clock side and the 9 o'clock side protrude outward. When the elastic cover member 9 is deformed between the elastic cover member 9 located at the central portion 12 and the watch case body 7 corresponding thereto, the deformed part of the elastic cover member 9 is inserted. Since the space portion 16 is provided, it is possible to obtain a high shock absorption.

すなわち、この腕時計ケース1では、図5に示すように、落下などによって弾性カバー部材9における3時側の側面が床などの平面Sに衝突し、図6に示すように、その衝撃が弾性カバー部材9の外側に突出した中央部12に加わると、この中央部12の弾性カバー部材9とこれに対応する腕時計ケース本体7との間に設けられた空間部16に、弾性カバー部材9の変形した一部が挿入することにより、衝撃を吸収して衝撃が腕時計ケース本体7に伝わるのを軽減することができるので、耐衝撃吸収性を確保することができる。   That is, in this wristwatch case 1, as shown in FIG. 5, the 3 o'clock side surface of the elastic cover member 9 collides with a flat surface S such as a floor by dropping or the like, and as shown in FIG. When added to the central portion 12 projecting outside the member 9, the elastic cover member 9 is deformed into a space portion 16 provided between the elastic cover member 9 of the central portion 12 and the watch case body 7 corresponding thereto. By inserting the part, it is possible to reduce the impact that is absorbed and transmitted to the wristwatch case body 7, so that it is possible to ensure shock absorption.

この場合、空間部16は、その厚みがビス11の首部11bの長さよりも少し短く、且つ腕時計ケース本体7の外周面における上下方向の広さがベゼル8の下部から裏蓋3の周辺に対応する腕時計ケース本体7の下部外周に亘って設けられているほか、腕時計ケース本体7の外周面に沿う方向の広さが、図4に示すように、3時側および9時側の各押釦5間に位置する広さで設けられているので、図6に示すように、弾性カバー部材9の中央部12が側面から衝撃を受けた際、腕時計ケース本体7の下部側に衝撃が伝わるだけで、腕時計ケース本体7内の時計モジュール4に衝撃が伝わるのを大幅に軽減することができる。   In this case, the space 16 has a thickness slightly shorter than the length of the neck 11 b of the screw 11, and the vertical width of the outer peripheral surface of the watch case body 7 corresponds from the lower part of the bezel 8 to the periphery of the back cover 3. In addition to being provided over the outer periphery of the lower part of the watch case main body 7, the width in the direction along the outer peripheral surface of the watch case main body 7 is shown in FIG. As shown in FIG. 6, when the central portion 12 of the elastic cover member 9 receives an impact from the side surface, the impact is only transmitted to the lower side of the watch case body 7 as shown in FIG. The impact transmitted to the watch module 4 in the watch case body 7 can be greatly reduced.

すなわち、弾性カバー部材9の中央部12が側面から衝撃を受けた際、図6に示すように、その中央部12の上部側で受けた衝撃は、ベゼル8に伝わり、このベゼル8を介して腕時計ケース本体7の上部側に伝わるが、ベゼル8が腕時計ケース本体7内の時計モジュール4の上側に位置しているので、時計モジュール4には衝撃が伝わりにくい。また、弾性カバー部材9の中央部12における下部側で受けた衝撃は、裏蓋3の周辺に位置する腕時計ケース本体7の下部側に伝わるが、この下部側が腕時計ケース本体7内の時計モジュール4の下側に位置しているので、時計モジュール4には衝撃が伝わりにくい。これにより、腕時計ケース本体7内の時計モジュール4を衝撃から確実に保護することができる。   That is, when the central portion 12 of the elastic cover member 9 receives an impact from the side, as shown in FIG. 6, the impact received on the upper side of the central portion 12 is transmitted to the bezel 8, and the bezel 8 passes through the bezel 8. Although transmitted to the upper side of the watch case body 7, the bezel 8 is located above the watch module 4 in the watch case body 7, so that the impact is hardly transmitted to the watch module 4. The impact received on the lower side of the central portion 12 of the elastic cover member 9 is transmitted to the lower side of the watch case body 7 located around the back cover 3, and this lower side is the watch module 4 in the watch case body 7. Since it is located on the lower side, the watch module 4 is less likely to receive an impact. Thereby, the timepiece module 4 in the wristwatch case body 7 can be reliably protected from impact.

また、この腕時計ケース1では、弾性カバー部材9が中央部12において腕時計ケース本体7に対してビス11により固定されているので、中央部12に位置する弾性カバー部材9とこれに対応する腕時計ケース本体7との間に空間部16が設けられていても、弾性カバー部材9を腕時計ケース本体7の外周面に対して確実に且つ良好に固定することができる。   Further, in this watch case 1, since the elastic cover member 9 is fixed to the watch case main body 7 by the screw 11 at the central portion 12, the elastic cover member 9 located at the central portion 12 and the corresponding watch case. Even if the space 16 is provided between the main body 7 and the elastic cover member 9, the elastic cover member 9 can be reliably and satisfactorily fixed to the outer peripheral surface of the watch case main body 7.

この場合、ビス11は、頭部11a、首部11b、ねじ部11cを有し、このねじ部11cが弾性カバー部材9の挿入孔部14を通して腕時計ケース本体7に設けられたねじ孔15に螺着するので、弾性カバー部材9の中央部12が側面から衝撃を受けて弾性変形する際、ビス11が動かずに、ビス11の首部11bに沿って弾性カバー部材9の中央部12を容易に且つ良好に弾性変形させることができ、これによりビス11で弾性カバー部材9を腕時計ケース本体7に対して固定しても、良好に衝撃を吸収することができる。   In this case, the screw 11 has a head portion 11a, a neck portion 11b, and a screw portion 11c. The screw portion 11c is screwed into a screw hole 15 provided in the watch case body 7 through the insertion hole portion 14 of the elastic cover member 9. Therefore, when the central portion 12 of the elastic cover member 9 is elastically deformed by receiving an impact from the side surface, the screw 11 does not move, and the central portion 12 of the elastic cover member 9 can be easily moved along the neck portion 11b of the screw 11. Therefore, even if the elastic cover member 9 is fixed to the wristwatch case body 7 with the screw 11, the shock can be absorbed well.

さらに、この腕時計ケース1では、押釦5の周辺に位置する弾性カバー部材9の箇所のうち、中央部12が、図1および図4に示すように、3時側の押釦5の間と9時側の押釦5の間とに位置して最も外側に突出して形成され、この中央部12から押釦5を挟んで反対側の箇所に位置する周側部13が押釦5の外面とほぼ同じ高さで、中央部12よりも低く形成されているので、腕時計ケース1が落下して腕時計ケース1の外周面が床などの平面Sに当接した際、弾性カバー部材9の中央部12および周側部13が床などの平面Sに当接しても、押釦5が床などの平面Sに接触しないため、押釦5を確実に且つ良好に保護することができる。   Furthermore, in this wristwatch case 1, the central portion 12 of the elastic cover member 9 located around the push button 5 is located between the push button 5 on the 3 o'clock side and 9 o'clock as shown in FIGS. The peripheral side portion 13 is located between the side push buttons 5 so as to protrude to the outermost side and is located on the opposite side of the push button 5 from the center portion 12. Therefore, when the wristwatch case 1 falls and the outer peripheral surface of the wristwatch case 1 comes into contact with the plane S such as the floor, the central portion 12 and the peripheral side of the elastic cover member 9 are formed.
