Description

【0001】
【発明の属する技術分野】
本発明は、手首に装着するリスト装置に関するものである。
【0002】
【従来の技術】
従来、腕時計等の手首に装着するリスト装置において、ねじ込み式裏蓋を有するものに耐衝撃構造を備える場合には、弾性体の緩衝部材を該ねじ込み式裏蓋の周囲に巻き付けた状態で、このねじ込み式裏蓋をリスト装置の本体ケースにねじ込む方法がとられていた。
【0003】
また、リスト装置において、ビス止め式裏蓋を有するものに耐衝撃構造を備える場合には、緩衝部材を裏蓋および本体ケースの外側に配して、ビス止めにより該本体ケースの周囲から該緩衝部材を本体ケースに固定するといった方法がとられていた。
【0004】
【発明が解決しようとする課題】
しかしながら、従来のリスト装置において、ねじ込み式裏蓋を有するものでは、上述したように、ねじ込み式裏蓋の周囲に弾性体の緩衝部材を巻き付けた状態で、このねじ込み式裏蓋を本体ケースにねじ込むため、ねじ込み強さによって、ねじ込み時の回転量に誤差が生じていた。従って、リスト装置本体の裏側に突出する緩衝突部を設けて、この突出部をリスト装置のバンドの基端部に位置させようとしてもねじ込み強さによって緩衝突部の位置がずれてしまうため、このような緩衝突部を有するような方向性のある緩衝部材を用いることができないという問題があった。
【0005】
また、ビス止め式裏蓋有するものでは、緩衝部材を本体ケースの周囲に対してビス止めするといった方法が採られていたため、該緩衝部材の寸法が大きくなってしまい、リスト装置のデザイン的な制約がでてしまうといった問題があった。
【0006】
そこで、本発明の課題は、ねじ込み式裏蓋を有するものでも緩衝突部を所定位置に配置することができるとともに、緩衝部材の寸法を小さく設定してリスト装置自体の外形寸法を小さく設定する等、デザイン性における自由度を高めることを可能とするリスト装置を提供することにある。
【0007】
【課題を解決するための手段】
以上の課題を解決すべく、この発明は、本体ケース(図2、図7等の本体ケース2)と、この本体ケースの裏面側に取り付けられた裏蓋(同図の裏蓋7)と、この本体ケースから裏面側に突出し該裏面側からの該本体ケースへの衝撃を緩衝する緩衝突部(同図の緩衝突部21)と前記本体ケースの裏面側に設けられた溝部(同図の溝部10)に嵌入される埋込部(同図の埋込部22)とを有する緩衝部材(同図の緩衝部材20)とを備え、前記埋込部を前記溝部に嵌入させ、前記緩衝突部を所定位置に位置決めして、前記裏蓋を前記本体ケースの裏面側に取付け、該緩衝部材を前記本体ケースに固定しており、前記埋込部は前記本体ケースの全周に亘って設けられていることを特徴とする。
【0008】
前記本体ケースは、例えば腕時計本体であることが挙げられるが、手首に装着して用いるものであればコンパス、高度計などその他のものでも良い。
前記溝部は、例えば、前記本体ケースの裏面側の周縁部に沿って設けられている。
前記裏蓋としては、例えば、ねじ込み式のものが挙げられるが、ビス止め式のものでも良い。
【0009】
【発明の実施の形態】
以下に、本発明に係るリスト装置の実施の各形態例を図1から図9に基づいて説明する。
【0010】
<第一の実施の形態例>
先ず、図1は本発明に係るリスト装置の一例としての腕時計を示す正面図、図2は図1のA−A断面図、図3は図1のB−B断面図、図4は腕時計の本体ケース2の裏側を示す正面図、図5は本発明に係る緩衝部材20を説明するための図であり、このうち、(a)は正面図、(b)は背面図、(c)の上半分は(a)のC−C断面図、(c)の下半分は(a)のC−C矢視図、(d)は(a)のD−D断面図、(e)は(a)のE−E断面図、(f)は(b)の矢印F方向から見た図である。
【0011】
図1から図3に示されるように、腕時計(リスト装置)の本体1は、本体ケース2に、緩衝部材20、裏蓋7、ベゼル4及びガラス5等が取り付けられるとともに、液晶表示パネル6等の内部機器が収納されて構成されている。
【0012】
図1に示されるように、本体ケース2の側部にはバンド取付部3,…が設けられ、該バンド取付部3,…にはバンド3A,3Aがバネ棒3B,3Bにより取り付けられている。
本体ケース2の上面には、図示しないEL素子を発光させるための押しボタン53,53が設けられ、本体ケース2の側面には、各種操作を行うための押しボタン41が設けられている。図3に示されるように、ベゼル4は緩衝部材45により緩衝性をもたされた状態で本体ケース2に固定されている。また、ガラス5はパッキン43を介して本体ケース2の開口部44(図4参照)に圧入固定されている。さらに、ガラス5を通して、ドットマトリックス表示部42および時刻等の情報表示を行う表示部51が透視できるようになっている。本体ケース2の内部には、見切り部材46が緩衝部材47により緩衝性を持たされた状態で固定され、この見切り部材46には、液晶表示パネル6が固定されている。本体ケース2の内部には、他にも、各種電子機器等からなる電子モジュール48が緩衝部材49および抑え板52を介して配置されている。
【0013】
本体ケース2の裏面側には、図4に示されるように、その周縁部に沿って、緩衝部材20を取り付けるための溝部10が形成されている。
【0014】
緩衝部材20は、図5に示されるように、本体1の裏面側から該本体1へ加わる衝撃を緩衝する緩衝突部21,21と、本体ケース2の裏面側の溝部10に嵌入される埋込部22とを備えている。
埋込部22は、例えば、本体ケース2の全周に亘って配置されるような円環状に形成されている。
緩衝部材20の緩衝突部21,21の基端部には、例えば、孔部25が設けられていてもよい。これにより、緩衝突部21,21がバンド3A,3Aのバネ棒3B,3Bを支点とした回動を阻害することなく、該回動につれて緩衝突部21,21も、その基端部を軸に変位することが容易になる。
また、緩衝突部21,21は、後述する裏蓋7の取付けの邪魔にならないような位置に取付けられている。さらに、緩衝突部21,21を12時−6時方向に小さくして、腕時計本体1の12時−6時方向の寸法ができるだけ小さくなるようになっている。
【0015】
緩衝部材20の埋込部22の側周部には、緩衝部材20を本体ケース2へ取り付ける際の周方向へのずれを防止するためのずれ防止爪23,…が形成されている。一方、本体ケース2の溝部10には、緩衝部材20のずれ防止爪23,…を係合させて、緩衝部材20の緩衝突部21,21を本体ケース2のバンド取付部3位置に保持させるための係止部11,…が形成されている。
【0016】
緩衝突部21,21は、バンド3A,3Aが取付けられるバンド取付部3,…側(バンドの基端部)に位置決め配置され、腕時計1を手首に装着する際に緩衝突部21,21が邪魔にならないようになっている。
【0017】
このように構成された緩衝部材20の本体ケース2への取付けは、埋込部22を本体ケース2の溝部10に嵌入させるとともに、ずれ防止爪23,…を係止部11,…に係合させて位置決めした状態にして、その裏側からOリング50を介して裏蓋7を本体ケース2に螺合させることによって行われている。
【0018】
このように緩衝部材20が取り付けられた状態において、緩衝突部21が本体1の裏側に突出した状態となるので、本体1の裏面側からの落下時等に、その突出した緩衝突部21によって、本体1の裏面側から本体1へ加わる衝撃を緩衝でき、本体1に強い衝撃が加わるのを防止して優れた保護機能を得ることができる。
【0019】
緩衝部材20の埋込部22は本体ケース2の全周に亘って接触した状態に配置されるので、裏蓋7による緩衝部材20の本体1への固定を、より確実に行うことができる。
【0020】
また、埋込部22の側周部に形成されたずれ防止爪23,…が溝部10に形成された係止部11,…に係合して、埋込部22の溝部10の周方向へずれないようになっているので、緩衝部材20が本体ケース2に対してずれることがない。
【0021】
そして、その緩衝部材20の緩衝突部21,21が、バンド取付部3,…側(バンドの基端部)に確実に位置決めされるので、腕時計を手首に装着した際に緩衝突部21,21が邪魔にならない。
【0022】
さらに、緩衝部材20を本体1へ装着するための埋込部22が本体1の溝部10内に納まり、緩衝突部21,21のみが本体1の裏側に露出するように設計することも可能なので、そうすることによって、リスト装置をよりフルメタルに近いデザインとすることができる。
【0023】
<第二の実施の形態例>
先ず、図6は本発明に係るリスト装置の一例としての腕時計を示す正面図、図7は図6のH−H断面図、図8は図6のI−I断面図、図9本発明に係る補強部材30を説明するための図である。
【0024】
ここで、第二の実施の形態例における腕時計の本体40の各構成要素は、上述した第一の実施の形態例における腕時計の本体1の各構成要素とほぼ同じであるので、同一の構成要素には同一の符号を付し、その説明を省略する。
【0025】
補強部材30は、図9に示されるように、例えば、緩衝部材20の埋込部22の全周に対応した円環状の形状に形成されており、該補強部材30を該埋込部22に対して相対回転しないように位置決めする位置決め爪31,…と、該埋込部22を補強する補強部32とを有している。
【0026】
緩衝部材20の埋込部22の裏側には、図5に示されるように、補強部材30の位置決め爪31,…が嵌入される嵌入溝24,…が形成されている。
【0027】
このように構成された緩衝部材20を本体ケース2に取り付ける際には、補強部材30の位置決め爪31,…を埋込部22の嵌入溝24,…にそれぞれ嵌入させ、補強部材30が埋込部22に対して相対回転しない状態にしてから、該緩衝部材20を上記第一の実施の形態のときと同様に本体ケース2に装着するようにすれば、該補強部材30の補強部31により、埋込部22がその全周に亘って補強されて本体ケース2への取り付け時などに破損しにくくなる。また、埋込部22が本体ケース2の溝部10から抜けたりすることがなくなる。
【0028】
以上のような構成の、第二の実施の形態例によれば、補強部材30により埋込部22を補強したので、埋込部22の強度が好適に得られ、埋込部22を薄型化・小型化しても該埋込部22が本体ケース2の溝部10から抜けたりすることがなく、該埋込部22の薄型化・小型化が図れる。従って、前記本体1自体のデザインも、薄型化・小型化することができる。
【0029】
また、補強部材30の位置決め爪31,…を埋込部22の嵌入溝24,…にそれぞれ嵌入させて、補強部材30を埋込部22に対して、相対回転しないように確実に位置決めしたので、補強部材30が埋込部22に対して回転してずれることを防止できる。
【0030】
なお、上記の第二の実施の形態例では、埋込部22を、その全周に亘って補強部材30によって補強する構成としたが、必ずしも埋込部22の全周に亘って補強する必要はなく、補強部材によって埋込部22の一部を補強することとしても良い。
また、補強部材30を埋込部22に沿わせて配設し、該補強部材30により埋込部22を補強する構成としたが、補強部材30を埋込部22に埋め込む構成としても良い。
【0031】
上記の第一・第二の実施の形態例では、リスト装置として、腕時計を示して説明を行ったが該リスト装置は、手首に装着して用いるものであればどのようなリスト装置(例えば、リスト型GPS、リスト型電子コンパスまたは電子機器類など)に適用してもよい。
また、図示例では、正面形状が円形状の本体1(本体ケース2)となっているが、本発明はこれに限られるものではなく、例えば、正面形状が四角形状の本体(本体ケース)として、溝部10、埋込部22等もこれに対応した形状のものとしても良い。
さらに、裏蓋7は、上述したようなねじ込み式裏蓋に限らず、本体ケース2の溝部10に埋込部22を嵌入した状態で、ビス止め式裏蓋で埋込部22を本体1に固定する構成としてもよい。
加えて、その他の具体的細部構造等は、本発明の要旨を逸脱しない範囲において適宜変更可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a wrist device worn on a wrist.
[0002]
[Prior art]
Conventionally, when a wrist device such as a wristwatch is equipped with a shock-proof structure on a wrist device having a screwed back cover, an elastic cushioning member is wound around the screwed back cover. The method of screwing the screw-in type back cover into the main body case of the wrist device has been taken.
[0003]
In addition, when the wrist device having a screw-type back cover is provided with an impact-resistant structure, a shock-absorbing member is arranged on the outside of the back cover and the main body case, and the buffer is secured from the periphery of the main body case by screws. The method of fixing a member to a main body case was taken.
[0004]
[Problems to be solved by the invention]
However, in a conventional wrist device having a screwed back cover, as described above, the screwed back cover is screwed into the main body case in a state where an elastic buffer member is wound around the screwed back cover. Therefore, an error has occurred in the amount of rotation during screwing depending on the screwing strength. Therefore, since the buffer protrusion protruding on the back side of the wrist device body is provided and the protrusion is positioned on the base end portion of the wrist device band, the position of the buffer protrusion is shifted due to the screwing strength. There is a problem that a directional cushioning member having such a cushioning protrusion cannot be used.
[0005]
Further, in the case of having a screw-type back cover, since the buffer member is screwed to the periphery of the main body case, the size of the buffer member becomes large, and the design restrictions of the wrist device are limited. There was a problem such as going out.
[0006]
Accordingly, an object of the present invention is to provide a shock-absorbing protrusion at a predetermined position even with a screw-in type back cover, and to set the size of the shock-absorbing member small to set the external size of the wrist device small. An object of the present invention is to provide a wrist device that can increase the degree of freedom in design.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention includes a main body case (main body case 2 in FIGS. 2 and 7), a back cover attached to the back side of the main body case (back cover 7 in the same figure), A buffer protrusion (buffer protrusion 21 in the figure) that protrudes from the main body case to the back side and cushions the impact on the main body case from the back side, and a groove (shown in the figure) provided on the back side of the main body case And a buffer member (buffer member 20 in the figure) having an embedded part (embedded part 22 in the figure) fitted in the groove part 10), the embedded part being fitted in the groove part, and the buffer protrusion The back cover is attached to the back side of the main body case, the buffer member is fixed to the main body case, and the embedded portion is provided over the entire circumference of the main body case. It is characterized by being.
[0008]
The main body case may be a wristwatch main body, for example, but may be another one such as a compass or an altimeter as long as the main body case is worn on the wrist.
The groove is provided, for example, along a peripheral edge on the back side of the main body case.
Examples of the back cover include a screw-in type, but a screw-type type may also be used.
[0009]
