本発明は、時計バンドや装飾具用バンドなどのバンドに用いられる中留および当該中留を備える時計に関する。 The present invention relates to a clasp used for a band such as a watch band or a band for ornaments, and a watch having the clasp.

従来、時計バンドや装身具用バンドに用いられる中留において、バンド長さの微調整手段を備えたものがある（例えば、特許文献１参照）。
特許文献１の中留は、一方のバンドに連結され且つロックピンが設けられた中板と、中板に連結された外板と、外板に連結された中留枠と、中留枠に取り付けられた一対のプッシュボタンと、一対のプッシュボタンを保持するプッシュボタン保持部材とを備えている。
バンド長さの微調整手段は、他方のバンドに連結され、中留枠に対して、バンドの長手方向にスライド可能に設けられたスライド板と、プッシュボタンの操作と連動して、バンドの短手方向に摺動して前記スライド板と係合可能な係合突出部とを備えている。
一対のプッシュボタンは、付勢手段によって互いに遠ざかる方向に付勢された際に、前記係合爪と係合する一対の係合部を備えている。また、この際、一対の係合突出部は、スライド板と係合して、スライド板がスライドすることを規制する。
一方、一対のプッシュボタンを押すと、一対の係合突出部とスライド板との係合が解除され、スライド板を中留枠に対してスライドさせることで、バンド長さを調整できる。また、一対のプッシュボタンを押すと、一対の係合部とロックピンとの係合が解除され、中留のロックが解除される。 Conventionally, some of the Nakadome used for watch bands and accessories bands are provided with means for finely adjusting the band length (see, for example, Patent Document 1).
The middle clasp of Patent Document 1 is formed on a middle plate connected to one band and provided with a lock pin, an outer plate connected to the middle plate, a middle retaining frame connected to the outer plate, and a middle retaining frame. It includes a pair of attached pushbuttons and a pushbutton holding member that holds the pair of pushbuttons.
The band length fine adjustment means is connected to the other band, and is provided so as to be slidable in the longitudinal direction of the band with respect to the retaining frame, and the band is shortened in conjunction with the operation of the push button. It is provided with an engaging protrusion that slides in the hand direction and can be engaged with the slide plate.
The pair of pushbuttons comprises a pair of engaging portions that engage the engaging claws when urged by the urging means in a direction away from each other. Further, at this time, the pair of engaging protrusions engage with the slide plate to restrict the slide plate from sliding.
On the other hand, when the pair of push buttons are pressed, the engagement between the pair of engaging protrusions and the slide plate is released, and the band length can be adjusted by sliding the slide plate with respect to the retaining frame. Further, when the pair of push buttons are pressed, the engagement between the pair of engaging portions and the lock pin is released, and the lock of the clasp is released.

特許文献１の中留は、バンドの長さを調整する際に操作するプッシュボタンと、中留のロックを解除するプッシュボタンとが同一であるため、バンドの長さを調整しようとしてプッシュボタンを押した際に、予期せずにロックが解除されてしまい、時計が手首から外れて落下してしまう可能性がある。
また、中留のロックを解除するためにプッシュボタンを押した際に、意図せずにバンドの長さも調整されてしまうことがあり、この場合は、再度、バンド長さを調整する必要がある。
このため、特許文献１の中留は、バンドの長さを調整する操作が難しいという課題がある。 In Patent Document 1, the push button operated when adjusting the length of the band and the push button for releasing the lock of the band are the same, so that the push button is pressed in an attempt to adjust the length of the band. When pressed, it may unexpectedly unlock and the watch may fall off your wrist.
Also, when the push button is pressed to unlock the clasp, the band length may be unintentionally adjusted. In this case, it is necessary to adjust the band length again. ..
For this reason, Nakadome of Patent Document 1 has a problem that it is difficult to adjust the length of the band.

本発明の目的は、バンド長さの調整操作を容易に行うことができる中留および時計を提供することにある。 An object of the present invention is to provide a clasp and a timepiece in which a band length adjustment operation can be easily performed.

The first engaging member has a first adjusting recess and a plurality of second adjusting recesses provided along the first direction, and the first engaging member engages with the lock pin inserted into the insertion hole. A second engaging portion is provided with an engaging portion and a first engaging claw that can be engaged with the first adjusting recess, and the second engaging member engages with the lock pin inserted into the insertion hole. A portion and a second engaging claw that can be engaged with the second adjusting recess are provided, and the first engaging portion and the second engaging portion are the first engaging member and the second engaging portion. When the members move in a direction away from each other, they engage with the lock pin, and when the first engaging member and the second engaging member move in a direction approaching each other, the engagement with the lock pin can be released. In the slide plate, the first engaging portion and the second engaging portion are engaged with the lock pin, and the first engaging claw and the second engaging claw slide. With the engaging position engaged with the first adjusting recess and the second adjusting recess of the plate, and the first engaging portion and the second engaging portion engaged with the lock pin. , The first engaging claw and the said The second engaging claw is configured to be movable to a non-engaging position disengaged from the first adjusting recess and the second adjusting recess of the slide plate.

本発明によれば、第１プッシュボタンおよび第２プッシュボタンを押して、第１係合部材および第２係合部材を近づけると、第１係合部および第２係合部とロックピンとの係合を解除でき、中留のロックを解除できる。
また、スライド板を係合位置から非係合位置に移動すると、第１係合爪および第２係合爪が、第１調整用凹部および第２調整用凹部から外れるため、スライド板を第１方向に沿ってスライド移動することができ、これによりバンド長さを調整できる。
したがって、中留のロックを解除する操作と、バンド長さを調整する操作が異なるため、バンド長さ調整を行う際に、予期せずにロックが解除されて時計が手首から外れて落下することを確実に防止できる。また、ロックを解除するために、意図せずにバンド長さも調整されることも確実に防止できる。したがって、バンド長さを容易に調整することができる。 According to the present invention, when the first push button and the second push button are pushed to bring the first engaging member and the second engaging member closer to each other, the first engaging portion and the second engaging portion are engaged with the lock pin. Can be unlocked and the lock of Nakadome can be unlocked.
Further, when the slide plate is moved from the engaged position to the non-engaged position, the first engaging claw and the second engaging claw are disengaged from the first adjusting recess and the second adjusting recess, so that the slide plate is first moved. It can slide along the direction, which allows the band length to be adjusted.
Therefore, the operation to unlock the clasp and the operation to adjust the band length are different, so when adjusting the band length, the lock is unexpectedly released and the watch falls off the wrist. Can be reliably prevented. In addition, it is possible to reliably prevent the band length from being unintentionally adjusted in order to release the lock. Therefore, the band length can be easily adjusted.

本発明の中留において、前記ユニット枠は、前記外板に近づく第３方向、および、前記外板から離れる第４方向に回動可能に前記外板に連結され、前記ユニット枠が前記第３方向に回動して前記外板に当接した状態では、前記スライド板は前記係合位置に移動され、前記ユニット枠が前記第４方向に回動して前記外板から離れた状態では、前記スライド板は前記非係合位置に移動されることが好ましい。 In the middle retaining of the present invention, the unit frame is rotatably connected to the outer plate in a third direction approaching the outer plate and a fourth direction away from the outer plate, and the unit frame is connected to the third direction. In a state where the slide plate is rotated in a direction and abuts on the outer plate, the slide plate is moved to the engaging position, and when the unit frame is rotated in the fourth direction and is separated from the outer plate, the slide plate is moved to the engaging position. The slide plate is preferably moved to the non-engaged position.

本発明によれば、ユニット枠を回動することで、スライド板を係合位置および非係合位置に移動できるので、スライド板を直接移動させる必要が無く、スライド板を外部に露出させる必要も無いため、中留の意匠性を向上できる。 According to the present invention, since the slide plate can be moved to the engaged position and the non-engaged position by rotating the unit frame, it is not necessary to move the slide plate directly, and it is also necessary to expose the slide plate to the outside. Since there is no such thing, the design of Nakadome can be improved.

本発明の中留において、前記中留カバーは、第１貫通孔が形成された第１側壁部と、第２貫通孔が形成された第２側壁部とを備え、前記第１プッシュボタンは、前記第１貫通孔に挿通された第１操作部を備え、前記第２プッシュボタンは、前記第２貫通孔に挿通された第２操作部を備え、前記中留カバーを、前記外板から離れる方向に移動すると、前記第１操作部および前記第２操作部を介して、前記ユニット枠が前記第４方向に回動し、前記中留カバーを、前記外板に近づく方向に移動すると、前記第１操作部および前記第２操作部を介して、前記ユニット枠が前記第３方向に回動することが好ましい。 In the retaining cover of the present invention, the retaining cover includes a first side wall portion on which a first through hole is formed and a second side wall portion on which a second through hole is formed, and the first push button is a method.

As shown in FIG. 2, with the lock of the clasp 1 unlocked, the wrist is passed through the bands 11 and 12, and the outer plate 30 is folded toward the middle plate 20. As a result, the lock pin 21 of the middle plate 20 passes through the insertion hole 811 of the unit frame 80, the insertion hole 98 of the urging member 90, and the insertion hole 776 of the guide frame 77, and the first engaging portion 715 and the second. It is inserted between the facing surfaces 715A and 725A of the engaging portion 725. The upper end of the lock pin 21 is a truncated cone-shaped umbrella portion 23, and the diameter of the upper bottom of the umbrella portion 23 is smaller than the diameter of the lower bottom of the umbrella portion 23. Further, the lower side of the facing surfaces 715A and 725A is an inclined surface inclined in a direction away from each other. The dimension between the lower ends of each inclined surface is made larger than the diameter of the upper bottom of the umbrella portion 23, and the dimension between the upper ends of each inclined surface is made smaller than the diameter of the lower bottom of the umbrella portion 23. Therefore, when the umbrella portion 23 is inserted between the facing surfaces 715A and 725A, the side surface of the umbrella portion 23 comes into contact with the inclined surfaces of the facing surfaces 715A and 725A, and the facing surfaces 715A and 725A are pushed open. Further, when the middle retaining body 4 is pushed toward the middle plate 20, the umbrella portion 23 of the lock pin 21 is disengaged from the facing surfaces 715A and 725A, and the shaft portion 22 is arranged between the facing surfaces 715A and 725A. Therefore, the facing surfaces 715A and 725A that have been expanded by the umbrella portion 23 move in a direction approaching each other by the urging force of the springs 75 and 76. As a result, the facing surfaces 715A and 725A of the first engaging portion 715 and the second engaging portion 725 come into contact with the shaft portion 22 of the lock pin 21, and the umbrella portion 23 of the lock pin 21 comes into contact with the engaging portions 715 and 725.

In this way, the wristwatch 100 can be removed from the wrist.

［バンド長さの調整方法］
次に、バンド長さを調整する方法について説明する。バンド長さを調整する方法として、バンド長さを長くしたり、短くすることができる第１の調整方法と、バンド長さを短くすることのみができる第２の調整方法がある。 [How to adjust the band length]
Next, a method of adjusting the band length will be described. As a method of adjusting the band length, there are a first adjustment method in which the band length can be lengthened or shortened, and a second adjustment method in which the band length can only be shortened.

［第１の調整方法］
第１の調整方法を図１２～１５をも参照して説明する。なお、図１２～１５では、スライド板５０を露出させるため、中留カバー４０を省略している。
第１の調整方法は、まず、中留カバー４０を外板３０から離れる方向（Ｚ１方向）に持ち上げる。ユーザーが中留カバー４０を指でつまんで外板３０から離れるように、Ｚ１方向に持ち上げると、図１２に示すように、プッシュボタン６１、６２の第１操作部６１１、第２操作部６２１が中留カバー４０の第１貫通孔４４、第２貫通孔４５に挿通されているため、ユニット枠８０と外板３０とを連結する連結ピン１５を回転中心として、中留本体４も外板３０から離れる第４方向（Ｒ１方向）に回転する。
ユニット枠８０が外板３０から離れる方向に回転すると、スライド板５０の下面にユニット枠８０の保持片部８５が当接するため、スライド板５０もユニット枠８０の回転に連動して、外板３０から離れるＺ１方向に移動する。 [First adjustment method]
The first adjustment method will be described with reference to FIGS. 12 to 15. In FIGS. 12 to 15, the clasp cover 40 is omitted in order to expose the slide plate 50.
The first adjustment method is to first lift the retaining cover 40 in the direction away from the outer plate 30 (Z1 direction). When the user picks up the retaining cover 40 with his fingers and lifts it in the Z1 direction so as to be away from the outer plate 30, the first operation unit 611 and the second operation unit 621 of the push buttons 61 and 62 are as shown in FIG. Since it is inserted through the first through hole 44 and the second through hole 45 of the retaining cover 40, the retaining body 4 also has the outer plate 30 with the connecting pin 15 connecting the unit frame 80 and the outer plate 30 as the center of rotation. Rotate in the fourth direction (R1 direction) away from.
When the unit frame 80 rotates in a direction away from the outer plate 30, the holding piece portion 85 of the unit frame 80 comes into contact with the lower surface of the slide plate 50, so that the slide plate 50 also interlocks with the rotation of the unit frame 80 and the outer plate 30 Move in the Z1 direction away from.

図１３に示すように、ボタンユニット６０は、ロックピン２１に係合部７１５、７２５が係合し、かつ、板バネ部９６、９７で上方に付勢されているため、係合部７１５、７２５がロックピン２１の傘部２３の下面に当接する位置に維持される。よって、第１係合爪７１６、第２係合爪７２６の高さ位置もほぼ変わらない。このため、スライド板５０がＺ１方向に移動すると、スライド板５０の調整用開口部５６、５７は、係合部７１５、７２５から外れ、スライド板５０はＸ１方向およびＸ２方向の両方向に移動可能な状態となる。したがって、スライド板５０が連結されているバンド１２をバンド１１側（Ｘ１方向側）に押し込めばバンド長さを短くでき、バンド１２を反対方向（Ｘ２方向）に引き出せばバンド長さを長くできる。なお、本実施形態では、係合爪７１６、７２６が係合する調整用開口部５６、５７として、それぞれ３個の調整用開口部５６Ａ～５６Ｃ、５７Ａ～５７Ｃが設けられているため、バンド長さを３段階に調整できる。 As shown in FIG. 13, in the button unit 60, since the engaging portions 715 and 725 are engaged with the lock pin 21 and are urged upward by the leaf spring portions 96 and 97, the engaging portion 715, The 725 is maintained at a position where it abuts on the lower surface of the umbrella portion 23 of the lock pin 21. Therefore, the height positions of the first engaging claw 716 and the second engaging claw 726 are almost the same. Therefore, when the slide plate 50 moves in the Z1 direction, the adjusting openings 56 and 57 of the slide plate 50 are disengaged from the engaging portions 715 and 725, and the slide plate 50 can move in both the X1 direction and the X2 direction. It becomes a state. Therefore, the band length can be shortened by pushing the band 12 to which the slide plate 50 is connected toward the band 11 side (X1 direction side), and the band length can be lengthened by pulling out the band 12 in the opposite direction (X2 direction). In this embodiment, as the adjusting openings 56 and 57 with which the engaging claws 716 and 726 are engaged, three adjusting openings 56A to 56C and 57A to 57C are provided, respectively, so that the band length is provided. You can adjust the size in 3 steps.

バンド長さの調整後、中留カバー４０を外板３０側に押し下げると、図１４および図１５に示すように、ユニット枠８０が外板３０に近づく第３方向（Ｒ２方向）に回動して外板３０に当接し、中留本体４の係合爪７１６、７２６が、スライド板５０の調整用開口部５６、５７に係合する。
係合爪７１６、７２６が調整用開口部５６、５７に係合している状態では、係止面部７１９、７２９が調整用開口部５６、５７に当接するため、スライド板５０をＸ２方向に移動すること、つまりバンド長さを長くすることはできない。例えば、図１４、１５では、係合爪７１６、７２６が、調整用開口部５６Ａ、５７Ａに係合しているため、スライド板５０をＸ２方向に移動することができない。
図１４、１５の状態から、バンド長さを長くする場合は、再度、中留カバー４０を持ち上げて、調整用開口部５６、５７から係合爪７１６、７２６を外し、バンド１２をバンド１１から離れる方向に引き出してスライド板５０をＸ２方向に移動すればよい。 After adjusting the band length, when the retaining cover 40 is pushed down toward the outer plate 30, the unit frame 80 rotates in the third direction (R2 direction) approaching the outer plate 30 as shown in FIGS. 14 and 15. The engaging claws 716 and 726 of the retaining body 4 engage with the adjusting openings 56 and 57 of the slide plate 50.
When the engaging claws 716 and 726 are engaged with the adjusting openings 56 and 57, the locking surface portions 719 and 729 come into contact with the adjusting openings 56 and 57, so that the slide plate 50 is moved in the X2 direction. You can't do that, that is, increase the band length. For example, in FIGS. 14 and 15, since the engaging claws 716 and 726 are engaged with the adjusting openings 56A and 57A, the slide plate 50 cannot be moved in the X2 direction.
When increasing the band length from the states shown in FIGS. 14 and 15, the retaining cover 40 is lifted again, the engaging claws 716 and 726 are removed from the adjusting openings 56 and 57, and the band 12 is removed from the band 11. The slide plate 50 may be moved in the X2 direction by pulling it out in the direction away from it.

［第２の調整方法］
第２の調整方法は、バンド長さを短くすることしかできないが、中留カバー４０を持ち上げる必要が無いものである。すなわち、係合爪７１６、７２６の傾斜面部７１８、７２８がＸ１方向に上向きに傾斜されており、かつ、係合ユニット７０が板バネ部９６、９７で上方に付勢されている構造を利用したものである。
例えば、係合爪７１６、７２６が調整用開口部５６Ｃ、５７Ｃに係合している状態で、スライド板５０をＸ１方向に移動すると、スライド板５０の調整用開口部５６Ｃ、５７Ｃのバンド１２側の面が傾斜面部７１８、７２８に当接する。このため、スライド板５０の移動に伴い、係合爪７１６、７２６はＺ２方向に押され、係合ユニット７０は付勢部材９０側に押される。このため、係合爪７１６、７２６が調整用開口部５６Ｃ、５７Ｃから外れる。スライド板５０をＸ１方向にさらに移動し、係合爪７１６、７２６が次の調整用開口部５６Ｂ、５７Ｂの位置に達すると、付勢部材９０の板バネ部９６、９７によって係合ユニット７０がＺ１方向に移動し、係合爪７１６、７２６が調整用開口部５６Ｂ、５７Ｂに係合する。これにより、バンド長さを１段階短くできる。
さらに、スライド板５０をＸ１方向に移動すると、同様の動作で係合爪７１６、７２６は調整用開口部５６Ａ、５７Ａに係合し、バンド長さをさらに１段階短くできる。
したがって、第２の調整方法によれば、中留カバー４０を持ち上げずに、バンド長さを短く調整できる。 [Second adjustment method]
The second adjustment method can only shorten the band length, but it is not necessary to lift the retaining cover 40. That is, the structure in which the inclined surface portions 718 and 728 of the engaging claws 716 and 726 are inclined upward in the X1 direction and the engaging unit 70 is urged upward by the leaf spring portions 96 and 97 is used. It is a thing.
For example, when the slide plate 50 is moved in the X1 direction while the engaging claws 716 and 726 are engaged with the adjusting openings 56C and 57C, the band 12 side of the adjusting openings 56C and 57C of the slide plate 50 The surface of the surface abuts on the inclined surface portions 718 and 728. Therefore, as the slide plate 50 moves, the engaging claws 716 and 726 are pushed in the Z2 direction, and the engaging unit 70 is pushed toward the urging member 90. Therefore, the engaging claws 716 and 726 are disengaged from the adjusting openings 56C and 57C. When the slide plate 50 is further moved in the X1 direction and the engaging claws 716 and 726 reach the positions of the next adjusting openings 56B and 57B, the engaging unit 70 is moved by the leaf spring portions 96 and 97 of the urging member 90. It moves in the Z1 direction, and the engaging claws 716 and 726 engage with the adjusting openings 56B and 57B. As a result, the band length can be shortened by one step.
Further, when the slide plate 50 is moved in the X1 direction, the engaging claws 716 and 726 are engaged with the adjusting openings 56A and 57A in the same operation, and the band length can be further shortened by one step.
Therefore, according to the second adjustment method, the band length can be shortened without lifting the retaining cover 40.

［実施形態の作用効果］
本実施形態によれば、中留１のロックを解除する場合は、プッシュボタン６１、６２を操作するのに対し、バンド長さを調整する場合は、中留カバー４０を引き上げてスライド板５０を移動させる。このため、バンド長さ調整を行う際に、予期せずにロックが解除されて時計が手首から外れて落下することを確実に防止できる。また、ロックを解除するために、意図せずにバンド長さも調整されることも確実に防止できる。したがって、バンド長さを容易に調整することができる。
さらに、ロック解除時に操作するプッシュボタン６１、６２ではなく、中留カバー４０を持ち上げてバンド長さを調整するため、ユーザーは、バンド長さを調整する操作を理解し易く、この点でも容易に操作できる。 [Action and effect of the embodiment]
According to the present embodiment, the push buttons 61 and 62 are operated when the lock of the clasp 1 is released, whereas the slide plate 50 is pulled up by pulling up the clasp cover 40 when adjusting the band length. Move it. Therefore, when adjusting the band length, it is possible to reliably prevent the watch from being unexpectedly unlocked and falling off the wrist. In addition, it is possible to reliably prevent the band length from being unintentionally adjusted in order to release the lock. Therefore, the band length can be easily adjusted.
Further, since the band length is adjusted by lifting the clasp cover 40 instead of the push buttons 61 and 62 operated at the time of unlocking, the user can easily understand the operation of adjusting the band length, and in this respect as well. Can be operated.

中留カバー４０を持ち上げた際に、中留１のロックを行うロックピン２１および第１係合部材７１、第２係合部材７２とで、係合ユニット７０の移動を規制しているので、スライド板５０の調整用開口部５６、５７を、係合爪７１６、７２６から確実に外すことができるとともに、中留１のロック用の機構を一部兼用しているので、部品数の増加を抑制でき、中留本体４の小型化および低コスト化を実現できる。 When the clasp cover 40 is lifted, the lock pin 21 that locks the clasp 1 and the first engaging member 71 and the second engaging member 72 restrict the movement of the engaging unit 70. The adjustment openings 56 and 57 of the slide plate 50 can be reliably removed from the engaging claws 716 and 726, and the locking mechanism of the clasp 1 is also partially used, so that the number of parts can be increased. It can be suppressed, and the size and cost of the Nakadome main body 4 can be reduced.

付勢部材９０をユニット枠８０内に組み込んで、係合ユニット７０を付勢しているので、中留１がロックされている状態では、係合ユニット７０の係合部７１５、７２５がロックピン２１の傘部２３に当接する状態に維持できる。すなわち、中留カバー４０を引き上げて、第１操作部６１１、第２操作部６２１を介してユニット枠８０もＲ１方向に回動した際には、板バネ部９６、９７が変形することで、係合ユニット７０に対してユニット枠８０を相対的に移動することができる。これにより、ユニット枠８０でスライド板５０を移動することができ、係合ユニット７０の位置は、ロックピン２１によって機械的に設定でき、スライド板５０の位置はユニット枠８０によって機械的に設定できるので、中留カバー４０を引き上げた際に、係合爪７１６、７２６を確実に調整用開口部５６、５７から外すことができる。したがって、バンド長さの調整を、安定して確実に実行できる。 Since the urging member 90 is incorporated in the unit frame 80 to urge the engaging unit 70, the engaging portions 715 and 725 of the engaging unit 70 are locked pins in the state where the clasp 1 is locked. It can be maintained in a state of being in contact with the umbrella portion 23 of 21. That is, when the retaining cover 40 is pulled up and the unit frame 80 also rotates in the R1 direction via the first operation unit 611 and the second operation unit 621, the leaf spring portions 96 and 97 are deformed. The unit frame 80 can be moved relative to the engaging unit 70. Thereby, the slide plate 50 can be moved by the unit frame 80, the position of the engaging unit 70 can be mechanically set by the lock pin 21, and the position of the slide plate 50 can be mechanically set by the unit frame 80. Therefore, when the retaining cover 40 is pulled up, the engaging claws 716 and 726 can be reliably removed from the adjusting openings 56 and 57. Therefore, the band length can be adjusted stably and reliably.

バンド長さを調整する方法として、中留カバー４０を引き上げて行う第１の調整方法の他に、中留カバー４０を引き上げずにスライド板５０をＸ１方向に移動する第２の調整方法を実現できる構成としたので、バンド長さを短くする調整をさらに容易に行うことができる。このため、ユーザーは、バンド長さを最も長くなる設定とした状態で、中留１をロックして手首に腕時計１００を装着してから、バンド１２をＸ１方向に押し込むことで、バンド長さを短くすることができ、適切な長さに容易に調整できる。 As a method of adjusting the band length, in addition to the first adjustment method of pulling up the clasp cover 40, a second adjustment method of moving the slide plate 50 in the X1 direction without pulling up the clasp cover 40 is realized. Since the configuration is such that the band length can be shortened, the adjustment for shortening the band length can be performed more easily. Therefore, the user locks the clasp 1 and wears the wristwatch 100 on the wrist with the band length set to be the longest, and then pushes the band 12 in the X1 direction to increase the band length. It can be shortened and easily adjusted to the appropriate length.

案内枠７７内に、第１係合部材７１、第２係合部材７２、バネ７５、７６を組み込んで係合ユニット７０としているため、案内枠７７を設けずに、ユニット枠８０内に直接、第１係合部材７１や第２係合部材７２を組み込む場合に比べて、ボタンユニット６０を容易に組み立てることができる。
さらに、第１係合部材７１や第２係合部材７２を付勢部材９０で直接付勢する場合に比べて、案内枠７７を介して係合ユニット７０として付勢できるため、第１係合部材７１、第２係合部材７２を安定して付勢することができ、係合爪７１６、７２６も同じ高さ位置に安定して設定できる。 Since the first engaging member 71, the second engaging member 72, the springs 75, and 76 are incorporated into the guide frame 77 to form the engaging unit 70, the guide frame 77 is not provided and the unit frame 80 is directly inserted. The button unit 60 can be easily assembled as compared with the case where the first engaging member 71 and the second engaging member 72 are incorporated.
Further, as compared with the case where the first engaging member 71 and the second engaging member 72 are directly urged by the urging member 90, the first engaging member 71 can be urged as the engaging unit 70 via the guide frame 77, so that the first engagement can be performed. The member 71 and the second engaging member 72 can be stably urged, and the engaging claws 716 and 726 can also be stably set at the same height position.

［他の実施形態］
なお、本発明は前述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。 [Other embodiments]
The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like to the extent that the object of the present invention can be achieved are included in the present invention.

前記実施形態では、第１係合部材７１、第２係合部材７２、バネ７５、７６を収納する案内枠７７を設けていたが、案内枠７７を設けずに、第１係合部材７１、第２係合部材７２、バネ７５、７６を、ユニット枠８０内に直接組み込んでもよい。 In the above embodiment, the guide frame 77 for accommodating the first engaging member 71, the second engaging member 72, the springs 75, and 76 is provided, but the first engaging member 71, without providing the guide frame 77, The second engaging member 72, the springs 75, and 76 may be incorporated directly into the unit frame 80.

前記実施形態では、第１係合爪７１６、第２係合爪７２６に傾斜面部７１８、７２８を設けていたが、傾斜面部７１８、７２８を無くしてもよい。この場合、前記第２の調整方法を実行できないため、バンド長さを調整する場合には、必ず中留カバー４０を引き上げてスライド板５０を係合位置から非係合位置に移動する必要がある。したがって、前記実施形態のように、傾斜面部７１８、７２８を設けることが好ましい。 In the above embodiment, the inclined surface portions 718 and 728 are provided on the first engaging claw 716 and the second engaging claw 726, but the inclined surface portions 718 and 728 may be eliminated. In this case, since the second adjustment method cannot be executed, when adjusting the band length, it is necessary to always pull up the retaining cover 40 and move the slide plate 50 from the engaged position to the non-engaged position. .. Therefore, it is preferable to provide the inclined surface portions 718 and 728 as in the above embodiment.

前記実施形態では、第１プッシュボタン６１、第２プッシュボタン６２を、第１係合部材７１、第２係合部材７２と別体で構成していたが、一体で構成してもよい。ただし、この場合は、ユニット枠８０や中留カバー４０に対して、第１プッシュボタン６１、第２プッシュボタン６２が相対的に移動できるように構成する必要がある。
このため、中留カバー４０と、ユニット枠８０とを別途連動して移動できるようにしたり、ユニット枠８０やスライド板５０を直接移動できるように構成すればよい。例えば、ユニット枠８０に対して、中留カバー４０を、スライド板５０を挿入可能な隙間を設けてネジ止めなどで固定してもよい。 In the above embodiment, the first push button 61 and the second push button 62 are configured separately from the first engaging member 71 and the second engaging member 72, but they may be configured integrally. However, in this case, it is necessary to configure the first push button 61 and the second push button 62 so as to be relatively movable with respect to the unit frame 80 and the retaining cover 40.
Therefore, the retaining cover 40 and the unit frame 80 may be separately interlocked and moved, or the unit frame 80 and the slide plate 50 may be configured to be directly movable. For example, the retaining cover 40 may be fixed to the unit frame 80 by screwing or the like with a gap into which the slide plate 50 can be inserted.

本発明の中留１は、時計バンドに限らず、例えばブレスレットやネックレスなどの装身具用バンドにも利用できる。 The Nakadome 1 of the present invention can be used not only for a watch band but also for an accessory band such as a bracelet or a necklace.
