Description

本発明は、バンドの取付構造及び時計に関するものである。   The present invention relates to a band mounting structure and a timepiece.

従来、時計等のケースにバンドを取り付ける構成として、バネ棒やビスを用いてバンドをケースに固定する構成が知られている。
例えば、特許文献１には、バネ棒によってバンドを時計ケースのバンド取付部に取り付ける構成が開示されている。
バネ棒によってバンドを時計ケースに取り付ける場合には、バンドの取付側に設けられているバネ棒を押し縮めて、バンド取付部に設けられた取付孔にバネ棒の両端部を挿入する。この場合、バネ棒はバネの反発力によって取付孔に固定され、ユーザが時計を使用している際に容易にバンドが外れないようにすることができる。 Conventionally, as a configuration for attaching a band to a case such as a watch, a configuration in which the band is fixed to the case using a spring bar or a screw is known.
For example, Patent Document 1 discloses a configuration in which a band is attached to a band attaching portion of a watch case by a spring bar.
When the band is attached to the watch case with the spring bar, the spring bar provided on the band attachment side is compressed and the both ends of the spring bar are inserted into the attachment holes provided in the band attachment part. In this case, the spring bar is fixed to the mounting hole by the repulsive force of the spring, and the band can be prevented from being easily detached when the user uses the timepiece.

案内溝５４は、バネ棒６をバンド取付部１５に装着する際にバネ棒６を所定の装着位置（本実施形態では、取付補助部材７の補助溝７４内）まで案内するものであり、脚部５の対向する面に、バンド２の装着方向手前側からバンド取付孔５１の開口部まで形成されている。 These band attachment holes 51 are provided with guide grooves 54 extending from the front side of the band 2 in the mounting direction toward the back side (the direction indicated by the one-dot chain line arrow in FIG. 2).
The guide groove 54 guides the spring bar 6 to a predetermined mounting position (in the auxiliary groove 74 of the mounting auxiliary member 7 in this embodiment) when the spring bar 6 is mounted on the band mounting portion 15. On the opposing surface of the part 5, the band 2 is formed from the front side in the mounting direction to the opening of the band attachment hole 51.

案内溝５４は、バンド２の装着方向手前側が奥側よりも深く、幅方向に広がる傾斜面となっていることが好ましい。このように、案内溝５４におけるバンド２の装着方向手前側に傾斜を設けることにより、バネ棒６を装着する際には、バネ棒６の端部を案内溝５４内に円滑に挿入でき、バネ棒６を案内溝５４の奥側に押し込むにしたがって案内溝５４の壁によりバネ棒６が押し縮められ、外側に押し広げようとするバネの反力を保ったまま所定の装着位置（本実施形態では、取付補助部材７の補助溝７４内）に嵌め込むことができる。   It is preferable that the guide groove 54 has an inclined surface that is deeper on the front side in the mounting direction of the band 2 than the back side and extends in the width direction. As described above, by providing an inclination on the front side of the band 2 in the guide groove 54 in the mounting direction, the end of the spring bar 6 can be smoothly inserted into the guide groove 54 when the spring bar 6 is mounted. As the rod 6 is pushed into the back side of the guide groove 54, the spring rod 6 is compressed by the wall of the guide groove 54, and the predetermined mounting position (this embodiment) is maintained while keeping the reaction force of the spring to be expanded outward. Then, it can be fitted in the auxiliary groove 74 of the auxiliary mounting member 7.

図３は、バンド取付部１５の脚部５及びその周辺を拡大した要部拡大斜視図である。
図３に示すように、本実施形態では、バンド取付孔５１は、後述する取付補助部材７のフランジ部７２と嵌合可能な段部５２を有する段付き孔となっている。

なお、取付孔側係止部５３及び補助部材側係止部７５とは、凹凸部に限定されない。フランジ部７２が段部５２に突き当てられた際に滑り止めとなるものであればよく、例えば、取付孔側係止部５３及び補助部材側係止部７５のいずれか一方が凸部であり、いずれか他方がこの凸部を受ける凹部であってもよい。また、取付孔側係止部５３及び補助部材側係止部７５をざらつきのある面としてもよいし、ゴム等の滑りにくい材料を貼り付ける等してもよい。 FIG. 3 is an enlarged perspective view of a main part in which the leg part 5 of the band attaching part 15 and its periphery are enlarged.
As shown in FIG. 3, in this embodiment, the band attachment hole 51 is a stepped hole having a step portion 52 that can be fitted to a flange portion 72 of the attachment auxiliary member 7 described later.
The stepped portion 52 is provided with a mounting hole side locking portion 53 that is locked to the auxiliary member side locking portion 75.
The attachment hole side latching portion 53 of the present embodiment is an uneven portion having a shape that fits with the auxiliary member side latching portion 75.
In addition, the attachment hole side latching | locking part 53 and the auxiliary member side latching | locking part 75 are not limited to an uneven | corrugated | grooved part. What is necessary is just to become a slip stopper when the flange part 72 is abutted against the step part 52, for example, either the attachment hole side latching part 53 or the auxiliary member side latching part 75 is a convex part. , One of the other may be a concave portion that receives this convex portion. Further, the attachment hole side locking portion 53 and the auxiliary member side locking portion 75 may be roughened surfaces, or a non-slip material such as rubber may be attached.

また、バンド取付部１５には、取付補助部材７が設けられている。
取付補助部材７は、例えば、ＰＯＭ（すなわち、ポリアセタール（polyacetal）又はポリオキシメチレン（polyoxymethylene））や、ＡＢＳ樹脂、ポリカーボネート等の硬質プラスチック、アルミニウム等で形成されている。なお、取付補助部材７を形成する材料は、ある程度硬質で割れにくい材料であればよく、ここに例示したものに限定されない。 Further, the band attaching portion 15 is provided with an attachment assisting member 7.
The attachment auxiliary member 7 is made of, for example, POM (that is, polyacetal or polyoxymethylene), a hard plastic such as ABS resin or polycarbonate, aluminum, or the like. In addition, the material which forms the attachment auxiliary member 7 should just be a material hard to a certain extent and is hard to break, and is not limited to what was illustrated here.

取付補助部材７は、貫通孔として形成されているバンド取付孔５１内に挿通される軸部７１と、軸部７１におけるバンド取付孔５１への挿入先端側に設けられた回転用操作部７３と、軸部７１の他端側に設けられ軸部７１の径よりも大きな径を有する係止用のフランジ部７２とを備えている。
図２等に示すように、本実施形態において、回転用操作部７３は、例えばマイナスドライバ等を係止することが可能な溝部である。 The attachment auxiliary member 7 includes a shaft portion 71 inserted into the band attachment hole 51 formed as a through hole, and a rotation operation portion 73 provided on the distal end side of the shaft portion 71 into the band attachment hole 51. And a locking flange portion 72 provided on the other end side of the shaft portion 71 and having a diameter larger than the diameter of the shaft portion 71.
As shown in FIG. 2 etc., in this embodiment, the rotation operation part 73 is a groove part which can latch a minus driver etc., for example.

取付補助部材７は、バンド取付孔５１内に挿入した際、軸部７１はバンド取付孔５１を貫通し、フランジ部７２が段部５２に係止されることで位置決めされるようになっている。
取付補助部材７は、バンド取付孔５１内に位置決めされた状態において、フランジ部７２側の端面が脚部５の端面とほぼ面一となるようになっている。 When the mounting auxiliary member 7 is inserted into the band mounting hole 51, the shaft portion 71 passes through the band mounting hole 51, and the flange portion 72 is locked to the stepped portion 52 so as to be positioned. .
The mounting auxiliary member 7 is configured so that the end surface on the flange portion 72 side is substantially flush with the end surface of the leg portion 5 in a state where the mounting auxiliary member 7 is positioned in the band mounting hole 51.

取付補助部材７のフランジ部７２には、脚部５の案内溝５４に対応する補助溝７４が形成されている。
取付補助部材７は、バンド取付孔５１の軸周りに回転させることで案内溝５４と補助溝７４とが連続する連結部材装着可能位置と、案内溝５４と補助溝７４とが不連続となる連結部材固定位置とを取り得るようになっている。 An auxiliary groove 74 corresponding to the guide groove 54 of the leg portion 5 is formed in the flange portion 72 of the attachment auxiliary member 7.
The attachment auxiliary member 7 is rotated about the axis of the band attachment hole 51 so that the connecting member mounting position where the guide groove 54 and the auxiliary groove 74 are continuous and the connection groove 54 and the auxiliary groove 74 are discontinuous. The member fixing position can be taken.

また、フランジ部７２の端面であってバンド取付孔５１の段部５２と対向する面には、取付孔側係止部５３と嵌り合う補助部材側係止部７５が設けられている。取付孔側係止部５３と補助部材側係止部７５とが嵌り合うことにより、取付補助部材７がバンド取付孔５１内において、軸周りに自由に回転することが規制される。
さらに、上述のように、補助部材側係止部７５は、取付孔側係止部５３と嵌り合う凹凸部であり、フランジ部７２の端面が段部５２に押し当てられた状態で取付補助部材７をバンド取付孔５１の軸周りに回転させることにより、補助部材側係止部７５が取付孔側係止部５３の凹凸を乗り越える際に「カチカチ」というクリック感が得られるようになっている。 Further, an auxiliary member side locking portion 75 that fits the mounting hole side locking portion 53 is provided on the end face of the flange portion 72 and facing the stepped portion 52 of the band mounting hole 51. The attachment hole side locking portion 53 and the auxiliary member side locking portion 75 are fitted to each other, so that the attachment auxiliary member 7 is restricted from freely rotating around the axis in the band attachment hole 51.
Further, as described above, the auxiliary member side locking portion 75 is an uneven portion that fits into the mounting hole side locking portion 53, and the mounting auxiliary member is in a state where the end surface of the flange portion 72 is pressed against the stepped portion 52. 7 is rotated around the axis of the band attachment hole 51, and the click feeling of “tick” is obtained when the auxiliary member side locking portion 75 gets over the unevenness of the mounting hole side locking portion 53. .

3 to 5, the illustration of the exterior member 12 is omitted for the sake of convenience of illustrating the details of the band attaching portion 15. 4 and 5, the illustration of the band 2 is omitted.

時計１００を組み立てる際には、まず、ケース本体１１の上に外装部材１２を被せて時計ケース１０を一体化させる。その後、図３に示すように、ケース本体１１の各脚部５のバンド取付孔５１にそれぞれ取付補助部材７の軸部７１を、一対の脚部５の対向する側から外側に向かって挿入する。
このとき、取付補助部材７のフランジ部７２が脚部５のバンド取付孔５１の段部５２に突き当たる位置まで取付補助部材７を挿入する。これにより、図４に示すように、脚部５の対向する側の端面と取付補助部材７のフランジ部７２の端面とがほぼ面一となり、取付補助部材７の軸部７１の先端部がバンド取付孔５１から外部に露出した状態となる。 When the timepiece 100 is assembled, first, the timepiece case 10 is integrated by covering the case main body 11 with the exterior member 12. After that, as shown in FIG. 3, the shaft portions 71 of the mounting auxiliary members 7 are respectively inserted into the band mounting holes 51 of the leg portions 5 of the case body 11 from the opposing sides of the pair of leg portions 5 toward the outside. .
At this time, the attachment auxiliary member 7 is inserted to a position where the flange portion 72 of the attachment auxiliary member 7 abuts against the stepped portion 52 of the band attachment hole 51 of the leg portion 5. As a result, as shown in FIG. 4, the end surface on the opposite side of the leg portion 5 and the end surface of the flange portion 72 of the mounting auxiliary member 7 are substantially flush with each other, and the tip end portion of the shaft portion 71 of the mounting auxiliary member 7 is the band. It will be in the state exposed to the exterior from the attachment hole 51. FIG.

バンド２を時計ケース１０に取り付ける際には、バンド２のケース取付部２１の貫通孔２２にバネ棒６を挿通させる。また、取付補助部材７の補助溝７４の向きを脚部５の案内溝５４の向きと合わせ、案内溝５４と補助溝７４とが連続した連結部材装着可能位置となるように調整する。
この状態で、バンド２のケース取付部２１を時計ケース１０の一対の脚部５の間に嵌め込む。このとき、バネ棒６の両端部を案内溝５４及び補助溝７４に嵌め込み、図４に示すように、溝に沿って奥側にスライド移動させる。バネ棒６は、案内溝５４及び補助溝７４の壁面に押されて押し縮められながら補助溝７４の最奥に達するまで溝の中を摺動する。
バネ棒６は、バネの反力により案内溝５４及び補助溝７４の壁面を押圧しており、このバネの反力により、取付補助部材７のフランジ部７２はバンド取付孔５１の段部５２に押し付けられた状態となる。これにより、バンド取付孔５１の段部５２に形成されている取付孔側係止部５３と取付補助部材７のフランジ部に設けられている補助部材側係止部７５とが互いに嵌り合い、取付補助部材７がバンド取付孔５１内において、軸周りに自由に回転することが規制される。 When the band 2 is attached to the watch case 10, the spring bar 6 is inserted through the through hole 22 of the case attachment portion 21 of the band 2. Further, the direction of the auxiliary groove 74 of the mounting auxiliary member 7 is adjusted to the direction of the guide groove 54 of the leg portion 5, and the guide groove 54 and the auxiliary groove 74 are adjusted to be a continuous connecting member mounting position.
In this state, the case mounting portion 21 of the band 2 is fitted between the pair of legs 5 of the watch case 10. At this time, both ends of the spring bar 6 are fitted into the guide groove 54 and the auxiliary groove 74, and as shown in FIG. 4, they are slid to the back side along the groove. The spring bar 6 slides in the groove until it reaches the innermost part of the auxiliary groove 74 while being compressed by the wall surfaces of the guide groove 54 and the auxiliary groove 74.
The spring bar 6 presses the wall surfaces of the guide groove 54 and the auxiliary groove 74 by the reaction force of the spring, and the flange portion 72 of the attachment auxiliary member 7 is moved to the step portion 52 of the band attachment hole 51 by the reaction force of the spring. It becomes a pressed state. As a result, the attachment hole side latching portion 53 formed in the step portion 52 of the band attachment hole 51 and the auxiliary member side latching portion 75 provided in the flange portion of the attachment auxiliary member 7 are fitted to each other and attached. The auxiliary member 7 is restricted from freely rotating around the axis in the band attachment hole 51.

バンド２を時計ケース１０に固定する際には、取付補助部材７の回転用操作部７３を指先又は図示しないマイナスドライバ等を用いて、図５に矢印で示すように、バンド取付孔５１の軸周りに回転させる。具体的には、マイナスドライバの先端部や爪等を回転用操作部７３の溝部に差し込み、係止させて、取付孔側係止部５３と補助部材側係止部７５との間の摩擦力に抗して取付補助部材７を回転させる。このとき、補助部材側係止部７５が取付孔側係止部５３の凹凸を乗り越えることにより適度なクリック感が得られる。
取付補助部材７を１８０度回転させ、図６に示すように、回転用操作部７３の溝部分をバンド取付孔１２１の近傍に設けられた指標１２２の位置と合わせると、フランジ部７２に形成されている補助溝７４の向きが反転し、案内溝５４と補助溝７４とが不連続となる連結部材固定位置となる（図５参照）。これにより、バネ棒６が外れずバンド２が時計ケース１０に固定された状態となる。また、バネ棒６のバネの押圧力により、補助部材側係止部７５が取付孔側係止部５３と嵌り合い、取付補助部材７の自由な回転が規制されるため、バンド２の固定状態が維持される。 When the band 2 is fixed to the watch case 10, the rotation operation portion 73 of the attachment assisting member 7 is used by using a fingertip or a minus driver (not shown) as shown by an arrow in FIG. Rotate around. More specifically, the frictional force between the attachment hole side locking portion 53 and the auxiliary member side locking portion 75 is obtained by inserting and locking the tip of the minus driver or the nail into the groove of the rotation operation portion 73. The auxiliary mounting member 7 is rotated against this. At this time, an appropriate click feeling can be obtained by the auxiliary member side locking portion 75 getting over the unevenness of the mounting hole side locking portion 53.
When the attachment assisting member 7 is rotated 180 degrees and the groove portion of the rotation operation portion 73 is aligned with the position of the index 122 provided in the vicinity of the band attachment hole 121 as shown in FIG. The direction of the auxiliary groove 74 is reversed, and the guide groove 54 and the auxiliary groove 74 become a connecting member fixing position where they are discontinuous (see FIG. 5). As a result, the spring bar 6 does not come off and the band 2 is fixed to the watch case 10. In addition, the auxiliary member side latching portion 75 is fitted with the mounting hole side latching portion 53 by the pressing force of the spring of the spring bar 6, and the free rotation of the mounting auxiliary member 7 is restricted. Is maintained.

また、バンド２を時計ケース１０から外す場合には、取付補助部材７をさらに１８０度回転させて、取付補助部材７の補助溝７４の向きを脚部５の案内溝５４と合わせ、案内溝５４と補助溝７４とが連続した連結部材装着可能位置とする。これにより、バンド２を時計ケース１０から取り外すことのできる状態となる。   Further, when removing the band 2 from the watch case 10, the attachment auxiliary member 7 is further rotated 180 degrees so that the direction of the auxiliary groove 74 of the attachment auxiliary member 7 is aligned with the guide groove 54 of the leg portion 5. And a connecting member mounting position where the auxiliary groove 74 is continuous. As a result, the band 2 can be removed from the watch case 10.

以上のように、本実施形態によれば、バンド取付部１５の脚部５にバンド取付孔５１と案内溝５４とを設け、案内溝５４に対応する補助溝７４を有する取付補助部材７をバンド取付孔５１内に挿通させる。そして、取付補助部材７を、案内溝５４と補助溝７４とが連続する連結部材装着可能位置に調整した上で、バンド２における時計ケース１０への取り付け側端部に設けられたバネ棒６を、案内溝５４及び補助溝７４に沿って装着方向手前側から奥側に向かって嵌め入れる。そして、バネ棒６を奥までスライドさせた後に取付補助部材７をバンド取付孔５１の軸周りに回転させることにより、案内溝５４と補助溝７４とが不連続となる連結部材固定位置とする。
これにより、特別な工具等を使用したり、難しい操作を行うことなく、取付補助部材７の回転用操作部７３にドライバや爪等を係止させて取付補助部材７を軸周りに回転させるだけで簡易にバンド２を時計ケース１０に固定することができる。連結部材固定位置となっているときにはバンド２を外すことのできない状態が維持される。
また、バンド２を交換する場合も、取付補助部材７を軸周りに回転させて案内溝５４と補助溝７４とを連続させるだけで、バンド２を時計ケース１０から簡易に取り外すことができる。
また、取付補助部材７のバンド取付孔５１への挿入先端側に溝状の回転用操作部７３が設けられているため、ドライバ等の身近な工具や爪等を回転用操作部７３に係止しやすく、容易に取付補助部材７を回転させて、バンド２の着脱を簡易に行うことができる。
バンド取付孔５１は、フランジ部７２と嵌合可能な段部５２を有する段付き孔となっているため、取付補助部材７を貫通孔であるバンド取付孔５１に挿入したときに逆側から取付補助部材７が抜け落ちるのを防止することができる。
また、フランジ部７２の端面には、補助部材側係止部７５が設けられ、バンド取付孔５１の段部５２には、補助部材側係止部７５に係止される取付孔側係止部５３が設けられている。これにより、回転用操作部７３を操作して取付補助部材７を回転させた後、取付補助部材７が自由に回転することを防止でき、時計１００の装着中に取付補助部材７が緩んでバンド２が外れるのを防ぐことができる。
本実施形態で、補助部材側係止部７５は凹部又は凸部であり、取付孔側係止部５３は、補助部材側係止部７５と嵌り合う形状の凹部又は凸部である。このため、確実に取付補助部材７が自由に回転することを防止でき、装着中に取付補助部材７が緩んでバンド２が外れるのを防ぐことができる。また、取付補助部材７を回転させると、取付孔側係止部５３及び補助部材側係止部７５の凹部又は凸部が互いに嵌り合うことで「カチカチ」とクリック感を得ることができる。これにより、回転操作を行うユーザにとって取付補助部材７を回転させている感覚が直感的に伝わり、操作が分かりやすい。
バンド取付部１５におけるバンド取付孔５１の近傍に、取付補助部材７の連結部材固定位置を示す指標１２２が設けられている。これにより、取付補助部材７をどこまで回転させればバネ棒６が固定されるのかが分かりやすく、バンド２の固定を容易に行うことができる。 As described above, according to the present embodiment, the band attachment hole 51 and the guide groove 54 are provided in the leg portion 5 of the band attachment portion 15, and the attachment auxiliary member 7 having the auxiliary groove 74 corresponding to the guide groove 54 is attached to the band. It is inserted into the mounting hole 51. Then, after adjusting the attachment auxiliary member 7 to a position where the connecting groove can be attached, where the guide groove 54 and the auxiliary groove 74 are continuous, the spring bar 6 provided at the end of the band 2 on the attachment side to the watch case 10 is attached. Then, it is fitted along the guide groove 54 and the auxiliary groove 74 from the front side in the mounting direction toward the back side. Then, after the spring bar 6 is slid to the back, the attachment auxiliary member 7 is rotated around the axis of the band attachment hole 51 to obtain a connecting member fixing position where the guide groove 54 and the auxiliary groove 74 are discontinuous.
Thereby, without using a special tool or performing a difficult operation, the driver or claw is locked to the rotation operation portion 73 of the attachment auxiliary member 7 and the attachment auxiliary member 7 is simply rotated around the axis. Thus, the band 2 can be easily fixed to the watch case 10. When in the connecting member fixing position, the state in which the band 2 cannot be removed is maintained.
Further, when the band 2 is exchanged, the band 2 can be easily detached from the watch case 10 by simply rotating the attachment assisting member 7 around the axis to make the guide groove 54 and the auxiliary groove 74 continuous.
In addition, since a groove-like rotation operation portion 73 is provided on the distal end side of the attachment auxiliary member 7 into the band attachment hole 51, a familiar tool such as a driver or a nail is locked to the rotation operation portion 73. The attachment auxiliary member 7 can be easily rotated and the band 2 can be easily attached and detached.
Since the band attachment hole 51 is a stepped hole having a step portion 52 that can be fitted to the flange portion 72, the attachment is made from the opposite side when the attachment auxiliary member 7 is inserted into the band attachment hole 51 that is a through hole. It is possible to prevent the auxiliary member 7 from falling off.
Further, an auxiliary member side locking portion 75 is provided on the end surface of the flange portion 72, and the mounting hole side locking portion that is locked to the auxiliary member side locking portion 75 is provided at the stepped portion 52 of the band mounting hole 51. 53 is provided. Thereby, after operating the rotation operation portion 73 to rotate the attachment assisting member 7, it is possible to prevent the attachment assisting member 7 from freely rotating, and the attachment assisting member 7 is loosened while the watch 100 is being worn. 2 can be prevented from coming off.
In the present embodiment, the auxiliary member side locking portion 75 is a concave portion or a convex portion, and the attachment hole side locking portion 53 is a concave portion or a convex portion having a shape that fits with the auxiliary member side locking portion 75. For this reason, it can prevent reliably that the attachment auxiliary member 7 rotates freely, and it can prevent that the attachment auxiliary member 7 loosens during mounting | wearing and the band 2 remove | deviates. Further, when the attachment assisting member 7 is rotated, the recesses or projections of the attachment hole side engaging portion 53 and the auxiliary member side engaging portion 75 are fitted to each other, so that a “clicking” feeling can be obtained. As a result, the user who performs the rotation operation intuitively conveys the feeling of rotating the attachment assisting member 7, and the operation is easily understood.
In the vicinity of the band attachment hole 51 in the band attachment portion 15, an index 122 indicating the connection member fixing position of the attachment auxiliary member 7 is provided. Thereby, it is easy to understand how far the spring bar 6 is fixed by rotating the attachment assisting member 7 and the band 2 can be fixed easily.

なお、以上本発明の実施形態について説明したが、本発明は、かかる実施形態に限定されず、その要旨を逸脱しない範囲で、種々変形が可能であることは言うまでもない。   Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the scope of the present invention.

例えば、本実施形態では、回転用操作部７３がマイナスドライバ等を係止可能な溝状に形成されている場合を例示したが、回転用操作部の形状はこれに限定されない。
例えば、図７に示すように、回転用操作部を指先等で直接摘むことが可能な凸状の摘み部７６としてもよい。なお、摘み部７６の形状等は図示例に限定されない。
また、回転用操作部として軸周りにローレット加工等を施した部分を形成しこれを指先等で直接回転させることができる構成としてもよい。
このように、回転用操作部を直接回転操作可能な形状、構成とした場合には、何ら工具等を用いなくても取付補助部材７の回転操作を行うことが可能となり、構成をより簡易にすることができる。 For example, in the present embodiment, the case where the rotation operation unit 73 is formed in a groove shape capable of locking a minus driver or the like is illustrated, but the shape of the rotation operation unit is not limited to this.
For example, as shown in FIG. 7, it is good also as the convex picking part 76 which can be picked directly by the fingertip etc. for the operation part for rotation. In addition, the shape of the knob | pick part 76 is not limited to the example of illustration.
Moreover, it is good also as a structure which can form the part which gave the knurling process etc. around the axis | shaft as a rotation operation part, and can rotate this directly with a fingertip.
As described above, when the rotation operation unit has a shape and configuration that can be directly rotated, it is possible to perform the rotation operation of the auxiliary mounting member 7 without using any tools, and the configuration can be simplified. can do.

また、本実施形態では、溝状の回転用操作部７３にドライバや爪等を係止して取付補助部材７を回転させる場合を例示したが、回転用操作部７３を回転させる構成はこれに限定されない。   Moreover, in this embodiment, although the case where a driver, a nail | claw, etc. were latched to the groove-shaped rotation operation part 73 and the attachment auxiliary member 7 was rotated was illustrated, the structure which rotates the rotation operation part 73 to this is shown. It is not limited.

例えば、図８（ａ）から図８（ｃ）に示すように、取付補助部材７の軸部７１の先端側に、軸部７１の径方向に撓み変形可能なスリット部７８と爪部７９とを有する回転用操作部７７を備えてもよい。なお、図８（ａ）から図８（ｃ）では外装部材１２及びバンド２の図示を省略している。
この場合、図８（ａ）に示すように、操作レバー９１と操作部嵌込孔９２とを備える操作補助部材９を回転用操作部７７に取り付けて取付補助部材７の回転操作を行う。
回転用操作部７７を操作補助部材９の操作部嵌込孔９２に挿入すると、スリット部７８が撓んで回転用操作部７７が軸部７１の径方向に押し縮められる。操作部嵌込孔９２内には回転用操作部７７の爪部７９が係止される爪係止部９３が形成されており、爪部７９が爪係止部９３に嵌ることで操作補助部材９が取付補助部材７に固定される。
この状態で、図８（ｂ）に示すように、バンド２に取り付けられたバネ棒６を案内溝５４及び補助溝７４にそって奥まで押し込む。そして、図８（ｃ）に示すように、操作補助部材９の操作レバー９１を１８０度反転させることにより、案内溝５４と補助溝７４とが不連続のバンド固定位置となり、バンド２が時計ケース１０に固定される。
これによれば、回転操作する部分を比較的大きくすることができ、回転操作しやすい構成となる。また、操作レバー９１の方向によって取付補助部材７がバンド固定位置にあるか否かが分かりやすく、バンド固定位置を示す指標１２２を設ける必要がない。 For example, as shown in FIG. 8A to FIG. 8C, a slit portion 78 and a claw portion 79 that can be bent and deformed in the radial direction of the shaft portion 71 on the distal end side of the shaft portion 71 of the mounting auxiliary member 7. You may provide the operation part 77 for rotation which has. 8A to 8C, the exterior member 12 and the band 2 are not shown.
In this case, as illustrated in FIG. 8A, the operation assisting member 9 including the operation lever 91 and the operation portion insertion hole 92 is attached to the rotation operation portion 77 to rotate the attachment assisting member 7.
When the rotation operation portion 77 is inserted into the operation portion insertion hole 92 of the operation assisting member 9, the slit portion 78 is bent and the rotation operation portion 77 is compressed in the radial direction of the shaft portion 71. A claw locking portion 93 that locks the claw portion 79 of the rotation operation portion 77 is formed in the operation portion insertion hole 92, and the claw portion 79 fits into the claw locking portion 93 so that the operation assisting member is formed. 9 is fixed to the mounting auxiliary member 7.
In this state, as shown in FIG. 8B, the spring rod 6 attached to the band 2 is pushed in along the guide groove 54 and the auxiliary groove 74. Then, as shown in FIG. 8 (c), when the operation lever 91 of the operation auxiliary member 9 is inverted 180 degrees, the guide groove 54 and the auxiliary groove 74 become discontinuous band fixing positions, and the band 2 becomes the watch case. 10 is fixed.
According to this, the part to be rotated can be made relatively large, and the rotation operation can be easily performed. Further, it is easy to understand whether or not the auxiliary mounting member 7 is in the band fixing position depending on the direction of the operation lever 91, and there is no need to provide an index 122 indicating the band fixing position.

なお、図８（ａ）から図８（ｃ）に示す操作補助部材９は、バンド交換の際等にユーザにおいて適宜着脱可能なものであってもよいし、操作補助部材９を装着したまま、時計１００を使用するものであってもよい。
また、回転用操作部７７及び操作補助部材９の形状、構成等は図示例に限定されず、適宜変形が可能である。 Note that the operation assisting member 9 shown in FIGS. 8 (a) to 8 (c) may be appropriately removable by the user when replacing the band or the like, while the operation assisting member 9 is mounted. A watch 100 may be used.
The shapes, configurations, and the like of the rotation operation unit 77 and the operation assisting member 9 are not limited to the illustrated examples, and can be appropriately modified.

また、本実施形態では、図９（ａ）に示すように、取付補助部材７の補助溝７４がバンド取付孔５１の中心に対応する位置までほぼ水平方向に形成されている場合を例示したが、補助溝７４の形状はこれに限定されない。
例えば、図９（ｂ）に示すように、取付補助部材７の補助溝７４１は、バンド取付孔５１の中心に対応する位置よりもバネ棒６の装着方向の奥側まで深く形成されていてもよい。
補助溝７４１をこのような形状とすることにより、取付補助部材７を連結部材固定位置まで回転させた場合にバネ棒６が外れにくくなる。また、水平方向の遊びが多くなるため、時計１００を装着している際に腕がむくんだりした場合に、腕の太さに応じて多少バンド長を変化させることができ、より装着感が向上する。
また、例えば、図９（ｃ）に示すように、取付補助部材７の補助溝７４２は、バンド２の装着方向手前側から奥側に向かって下降するように傾斜を設けて形成されていてもよい。
補助溝７４２をこのような形状とすることにより、バンド２の着脱時において、バネ棒６を補助溝７４２内に引き込みやすくなり、バネ棒６の嵌め込みが容易となる。
また、バネ棒６を固定するために取付補助部材７を回転させた際、補助溝７４２の形状に沿ってバネ棒６が上方向に引き上げられることにより、バネ棒６が取り付けられているバンド２自体を上方、すなわち、時計ケース１０の外装部材１２側に押し付けることができ、時計ケース１０とバンド２との一体感を高めることができる。 Further, in the present embodiment, as illustrated in FIG. 9A, the case where the auxiliary groove 74 of the mounting auxiliary member 7 is formed in a substantially horizontal direction up to a position corresponding to the center of the band mounting hole 51 is illustrated. The shape of the auxiliary groove 74 is not limited to this.
For example, as shown in FIG. 9B, the auxiliary groove 741 of the mounting auxiliary member 7 may be formed deeper in the mounting direction of the spring bar 6 than the position corresponding to the center of the band mounting hole 51. Good.
By forming the auxiliary groove 741 in such a shape, the spring bar 6 is unlikely to come off when the attachment auxiliary member 7 is rotated to the connecting member fixing position. In addition, since the play in the horizontal direction increases, when the arm is swollen while wearing the watch 100, the band length can be changed slightly depending on the thickness of the arm, and the feeling of wearing is further improved. To do.
For example, as shown in FIG. 9C, the auxiliary groove 742 of the attachment auxiliary member 7 may be formed with an inclination so as to descend from the front side in the mounting direction of the band 2 toward the back side. Good.
By forming the auxiliary groove 742 in such a shape, the spring bar 6 can be easily pulled into the auxiliary groove 742 when the band 2 is attached and detached, and the spring bar 6 can be easily fitted.
Further, when the auxiliary mounting member 7 is rotated to fix the spring bar 6, the spring bar 6 is pulled upward along the shape of the auxiliary groove 742, whereby the band 2 to which the spring bar 6 is attached. The watch case 10 can be pressed upward, that is, the exterior member 12 side of the watch case 10, and the sense of unity between the watch case 10 and the band 2 can be enhanced.

また、本実施形態では、対向する一対の脚部５の両方に貫通孔としてのバンド取付孔５１が穿設され、このバンド取付孔５１の双方に取付補助部材７が設けられて、取付補助部材７がバネ棒６の両方の端部に取り付けられる場合を例示したが、貫通孔としてのバンド取付孔５１は一対の脚部５の双方に設けられている必要はなく、一方のバンド取付孔５１は貫通していない凹部としてもよい。
この場合には、案内溝５４及び取付補助部材７は、貫通孔であるバンド取付孔５１の側のみに設けられ、バネ棒６の一方側の端部のみが取付補助部材７の補助溝７４に嵌め込まれる。
このように、案内溝５４及び取付補助部材７を脚部５の一方のみに設けるとした場合でも、バンド２を着脱する際に、バネ棒６の一端部を凹部であるバンド取付孔５１にはめ込んだ後、バネ棒６を斜めにしながら他方のバンド取付孔５１に設けられている案内溝５４を介して取付補助部材７に係止させることにより、バンド２の着脱を行うことが可能である。
案内溝５４及び取付補助部材７を脚部５の一方のみに設ける場合には、部品点数を少なくすることができる。 Further, in this embodiment, band attachment holes 51 as through holes are formed in both of the pair of opposing leg portions 5, and the attachment auxiliary member 7 is provided in both of the band attachment holes 51, so that the attachment auxiliary member is provided. Although the case where 7 is attached to both ends of the spring bar 6 is illustrated, the band attachment holes 51 as through holes need not be provided in both the pair of leg portions 5, and one of the band attachment holes 51. It is good also as a recessed part which has not penetrated.
In this case, the guide groove 54 and the mounting auxiliary member 7 are provided only on the side of the band mounting hole 51 that is a through hole, and only one end of the spring bar 6 is formed in the auxiliary groove 74 of the mounting auxiliary member 7. It is inserted.
As described above, even when the guide groove 54 and the attachment auxiliary member 7 are provided only on one of the leg portions 5, one end of the spring bar 6 is fitted into the band attachment hole 51 that is a recess when the band 2 is attached or detached. After that, the band 2 can be attached and detached by locking the spring bar 6 to the attachment auxiliary member 7 via the guide groove 54 provided in the other band attachment hole 51 while making the spring bar 6 slant.
When the guide groove 54 and the mounting auxiliary member 7 are provided only on one of the leg portions 5, the number of parts can be reduced.

また、本実施形態では、バネ棒６を固定する場合に、取付補助部材７を１８０度回転させて、案内溝５４と補助溝７４とが完全に逆向きとなるようにする場合を例示したが、取付補助部材７を回転させる回転量はこれに限定されない。
取付補助部材７は、バンド取付孔５１の軸周りに回転させることで案内溝５４と補助溝７４とが連続する連結部材装着可能位置と、案内溝５４と補助溝７４とが不連続となる連結部材固定位置とを取り得るものであればよく、例えば、取付補助部材７を９０度回転させて案内溝５４と補助溝７４とが直交する位置を連結部材固定位置としてもよい。 In the present embodiment, when the spring bar 6 is fixed, the attachment auxiliary member 7 is rotated 180 degrees so that the guide groove 54 and the auxiliary groove 74 are completely opposite to each other. The amount of rotation for rotating the attachment assisting member 7 is not limited to this.
The attachment auxiliary member 7 is rotated about the axis of the band attachment hole 51 so that the connecting member mounting position where the guide groove 54 and the auxiliary groove 74 are continuous and the connection groove 54 and the auxiliary groove 74 are discontinuous. For example, a position where the guide groove 54 and the auxiliary groove 74 are orthogonal to each other by rotating the attachment auxiliary member 7 by 90 degrees may be set as the connecting member fixing position.

また、本実施形態では、フランジ部７２の端面に補助部材側係止部７５を設け、バンド取付孔５１の段部５２に取付孔側係止部５３を設けて、補助部材側係止部７５と取付孔側係止部５３とを噛み合わせることにより取付補助部材７の自由な回転を規制する構成としたが、取付補助部材７の自由な回転を規制する構成はこれに限定されない。
例えば、脚部５の外側面等に、取付補助部材７の回転用操作部７３又は回転用操作部に係止される操作補助部材（例えば、図８（ａ）から図８（ｃ）に示す操作補助部材９）を係止する爪部を設ける等、ロック機構を備える構成としてもよい。この場合には、補助部材側係止部７５および取付孔側係止部５３を設ける必要がない。 In the present embodiment, the auxiliary member side locking portion 75 is provided on the end surface of the flange portion 72, the mounting hole side locking portion 53 is provided in the stepped portion 52 of the band mounting hole 51, and the auxiliary member side locking portion 75 is provided. However, the configuration for restricting the free rotation of the mounting auxiliary member 7 is not limited to this.
For example, an operation auxiliary member 73 (for example, shown in FIGS. 8A to 8C) that is locked to the rotation operation portion 73 of the attachment auxiliary member 7 or the rotation operation portion on the outer surface of the leg portion 5 or the like.
