Description

本発明は、バンド等の被締結部材を締結する締結具に関する。また、この締結具を備えた長尺体や、この長尺体を備えた携帯機器、時計、および装身具などに関する。   The present invention relates to a fastener for fastening a member to be fastened such as a band. The present invention also relates to a long body including the fastener, a portable device including the long body, a watch, and a jewelry.

従来、時計バンドの開放端同士を締結するタイプの中留として、例えばつく棒（突棒）が突設されバンドに回動自在に設けられるフレームと、ばね力でつく棒を係止するプッシュ中留部材とを備えたものが知られている（特許文献１）。
このような中留のつく棒は、フレームから立ち上がる小径部と、小径部から膨出した大径部とを有する。そして、中留を留める際には、つく棒をバンドの孔に挿通し、バンドの孔から突出したつく棒の大径部をプッシュ中留部材の穴に係合させる。 Conventionally, as a type of intermediate bolt that fastens the open ends of a watch band, for example, a frame that is provided with a stick (protrusion stick) that is pivotably provided on the band and a push that locks the stick attached with a spring force The thing provided with the retaining member is known (patent document 1).
Such a rod with a middle end has a small-diameter portion that rises from the frame and a large-diameter portion that bulges from the small-diameter portion. Then, when fastening the retainer, the stick rod is inserted into the hole of the band, and the large diameter portion of the stick rod protruding from the hole of the band is engaged with the hole of the push retainer member.

特開平１０−２８６０５号公報Japanese Patent Laid-Open No. 10-28605

しかしながら、特許文献１のような中留には、次のような課題がある。
（１）腕への着脱の都度、バンドの孔につく棒を抜き挿ししなくてはならず、バンドの孔からつく棒を抜く際に、つく棒の大径部がバンド裏面側でバンド孔の周縁に引っ掛かるので、バンド孔の近傍が傷みやすい。具体的に、バンドで装着された時計の携帯時にはバンドの剛性によって引張力が作用するため、つく棒の軸とバンド孔の中心とがずれてつく棒の小径部がバンド孔の内周面に当接し、バンド孔の周縁に大径部が引っ掛かった状態からつく棒を抜くため、バンド孔の近傍が傷みやすい。
このように、バンド孔の位置でつく棒とプッシュ中留部材とを係合させる構成では、着脱時にバンドの一部分のみに負荷が掛かるため、バンドの耐久性が低い。 However, Nakadome like Patent Document 1 has the following problems.
(1) The rod attached to the hole of the band must be removed and inserted every time it is attached to or detached from the arm. When removing the stick attached to the hole of the band, the large diameter part of the attached rod is the band hole on the back side of the band. Since it is caught on the periphery of the band, the vicinity of the band hole is easily damaged. Specifically, when carrying a watch equipped with a band, a tensile force acts on the band due to the rigidity of the band, so that the small diameter part of the rod that sticks out of the center of the band rod and the center of the band hole is located on the inner peripheral surface of the band hole. Since the stick sticking out from the state in which the large diameter portion is caught on the periphery of the band hole is pulled out, the vicinity of the band hole is easily damaged.
In this way, in the configuration in which the stick attached at the position of the band hole and the push pinning member are engaged, a load is applied only to a part of the band at the time of attachment / detachment, and the durability of the band is low.

（２）つく棒をバンド孔に挿入する際に、つく棒とバンド孔との位置の見当を付けづらいため、装着操作が困難である。すなわち、バンドの開放端同士を締結する場合はバンドとバンドとの位置決めが必要であり、一方のバンドに設けられたつく棒と他方のバンドの孔との位置を合わせなくてはならないが、つく棒がフレームの裏側に隠れて見えづらい。
なお、特許文献１とは反対側の位置につく棒が設けられた構成、例えば腕に当接するプレート部材などにつく棒が突設され、このプレートにバンドを被せるようにしてバンド孔につく棒を挿通させる構成の場合なども、バンドの裏側につく棒が隠れるため、つく棒とバンド孔との位置を合わせづらいという事情は変わらず、装着操作が困難である。
また、バンドには複数の孔が形成されており、腕への着脱の都度、所定の孔につく棒を挿通できるとは限らないため、締結時のバンドの長さが所望の長さとならない場合がある。 (2) When the stick is inserted into the band hole, it is difficult to register the position of the stick and the band hole, so that the mounting operation is difficult. That is, when the open ends of the band are fastened, positioning of the band and the band is necessary, and the position of the stick provided on one band and the hole of the other band must be aligned. The stick is hidden behind the frame and difficult to see.
In addition, the structure provided with the stick | rod attached to the position on the opposite side to patent document 1, for example, the stick | stick sticking to the plate member etc. which contact | abut an arm is protrudingly provided, and the stick | rod which sticks to a band hole so that this plate may be covered with a band Also in the case of a configuration in which the stick is inserted, the stick attached to the back side of the band is hidden, so the situation that it is difficult to align the stick and the band hole is not changed, and the mounting operation is difficult.
Also, the band has a plurality of holes, and it is not always possible to insert a rod attached to a predetermined hole every time it is attached to or detached from the arm, so the band length at the time of fastening is not the desired length There is.

そこで、本発明の目的は、締結操作および締結解除の操作が容易で、かつバンド等の被締結部材の耐久品質に優れた締結具、この締結具を備えた長尺体、およびこの長尺体を備えた携帯機器、時計、並びに装身具を提供することにある。   Accordingly, an object of the present invention is to provide a fastener that is easy to perform a fastening operation and a fastening release operation and that is excellent in durability quality of a member to be fastened such as a band, a long body including the fastener, and the long body. A portable device, a watch, and a jewelry provided with the above.

And the second member are engaged with each other, and the first member is a side wall provided on each side of the one fastened member in a direction intersecting the sliding direction. And a first mounting member having a connecting portion that connects these side walls, and a push button that is biased from the inside to the outside of the fastened member in a direction that intersects the sliding direction of the fastened member. A button unit sandwiching the one fastened member between the first mounting member and the second member on both sides in a direction intersecting the sliding direction of the other fastened member In A second attachment member having a side wall attached to a predetermined position of the member to be fastened, wherein the first attachment member and the button unit are attached to a predetermined position of the one member to be fastened; And an engaging projection that engages with the side wall of the second mounting member when the members to be fastened are slid together with the push button, and the side wall of the second mounting member is It has an engagement concave part into which the engagement convex part is inserted from the inside.

以下では、便宜上、被締結部材のことをバンドと称するが、本発明における被締結部材はバンドに限らない。すなわち、本発明の締結具は、被締結部材同士がスライドされた際に第１部材と第２部材とが係合する構造に特徴を有しており、被締結部材の形状等は、スライド可能である限り、任意に構成できる。また、以下では、便宜上、被締結部材のスライド方向をバンドの長さ方向、被締結部材のスライド方向と交差する方向をバンドの幅方向、ということがある。
なお、被締結部材は、部材の部分であってもよい。 Hereinafter, for the sake of convenience, the fastened member is referred to as a band, but the fastened member in the present invention is not limited to a band. That is, the fastener of the present invention is characterized by the structure in which the first member and the second member engage when the members to be fastened are slid, and the shape of the member to be fastened is slidable. As long as it is, it can be arbitrarily configured. In the following, for the sake of convenience, the sliding direction of the member to be fastened may be referred to as the band length direction, and the direction intersecting the sliding direction of the member to be fastened may be referred to as the band width direction.
The fastened member may be a member part.

本発明において、第１取付部材およびボタンユニットを有する第１部材は、適宜な手段によって一方のバンド（被締結部材）の所定位置に取り付けられている。このような手段としては例えば、これらの第１取付部材およびボタンユニットの一方に、他方との間にバンドを押圧保持する突起やくさびなどであってよい。
また、第２取付部材を有する第２部材は、適宜な手段によって他方のバンド（被締結部材）の所定位置に取り付けられる。例えば、他方のバンドの幅方向（バンドのスライド方向と交差する方向）に沿って設けられた棒状部材の両端部をそれぞれ第２取付部材の側壁に係合させることにより、第２取付部材が他方のバンドの所定位置に取り付けられる。 In the present invention, the first attachment member and the first member having the button unit are attached to a predetermined position of one band (fastened member) by an appropriate means.

As shown in FIG. 5, the button unit frame 31 is formed into a substantially rectangular cross-section by bending using a thin metal plate, and a hole 311 through which the protrusion 33 passes is formed at the abutting portion of the thin plate end. .
Further, as shown in FIGS. 6 and 7, a stopper 312 that locks each button member 32 is formed by cutting and raising a part of the bottom surface of the button unit frame 31.

各ボタン部材３２は、図６に示すように、プッシュボタン３２１と係合凸部３２２とを切欠３２３を挟んで一体に有する板状の部材とされている。これらのボタン部材３２，３２は、圧縮コイルばね３２４，３２４によってボタンユニット枠３１の両端の開口の内側から外側に向かって付勢されており、各ボタン部材３２にそれぞれ形成された貫通孔３２５に前記ストッパ３１２が挿入されることにより、当該ボタン部材３２，３２はボタンユニット枠３１に係止されている。
コイルばね３２４，３２４はそれぞれ、ボタンユニット枠３１の両側面部側で、ボタン部材３２，３２のそれぞれに形成された切欠３２６，３２６の間に配置されている。 As shown in FIG. 6, each button member 32 is a plate-like member that integrally includes a push button 321 and an engaging projection 322 with a notch 323 interposed therebetween. These button members 32, 32 are urged from the inside to the outside of the openings at both ends of the button unit frame 31 by compression coil springs 324, 324, and are inserted into through holes 325 formed in the respective button members 32. The button members 32 and 32 are locked to the button unit frame 31 by inserting the stopper 312.
The coil springs 324 and 324 are arranged between the notches 326 and 326 formed in the button members 32 and 32 on the both side surfaces of the button unit frame 31, respectively.

プッシュボタン３２１は、平面矩形状に形成され、第１取付部材２０（図４）の側壁２１に形成された開口部２１１の内側から外側に突出する。このプッシュボタン３２１は、開口部２１１の高さよりも若干小さい厚さで、かつ開口部２１１の幅よりも若干小さい幅で形成されている。
ここで、ストッパ３１２が挿入される前記貫通孔３２５の寸法は、両側のプッシュボタン３２１，３２１をバンド１１（図３）の幅方向内側に押し込んだ際に、側壁２１，２１の内面間の寸法よりもプッシュボタン３２１，３２１の先端間の寸法が小さくなり開口部２１１から各プッシュボタン３２１が外れるプッシュボタン３２１の最大押し込み量を実現する寸法で形成されている。
なお、プッシュボタン３２１をコイルばね３２４のばね力に抗して押していない状態では、コイルばね３２４のばね力により、ストッパ３１２が貫通孔３２５の内壁に当接していることが好ましい。これにより、プッシュボタン３２１の遊びをなくすことができる。 The push button 321 is formed in a planar rectangular shape and protrudes from the inside to the outside of the opening 211 formed in the side wall 21 of the first mounting member 20 (FIG. 4). The push button 321 has a thickness slightly smaller than the height of the opening 211 and a width slightly smaller than the width of the opening 211.

The dimension between the tips of the push buttons 321 and 321 is smaller than that of the push button 321 so that the push button 321 is released from the opening 211 so that the push button 321 can be pushed in the maximum amount.
In the state where the push button 321 is not pushed against the spring force of the coil spring 324, it is preferable that the stopper 312 is in contact with the inner wall of the through hole 325 by the spring force of the coil spring 324. Thereby, the play of the push button 321 can be eliminated.

係合凸部３２２は、第１取付部材２０（図４）の側壁２１と重ならない位置でコイルばね３２４による付勢方向に沿って突出している。この係合凸部３２２におけるボタンユニット枠３１の側面側の部分は、バンド１１（図３）の長さ方向と幅方向との両方に対して斜めに形成されたＲ形状の斜面３２２Ａとされている。一方、係合凸部３２２の切欠３２３側の立ち上がり部３２２Ｂは、バンド１１の長さ方向に対して略直角に形成されている。   The engaging convex part 322 protrudes along the urging direction by the coil spring 324 at a position not overlapping with the side wall 21 of the first mounting member 20 (FIG. 4). The side portion of the button unit frame 31 in the engagement convex portion 322 is an R-shaped slope 322A formed obliquely with respect to both the length direction and the width direction of the band 11 (FIG. 3). Yes. On the other hand, the rising portion 322 </ b> B on the notch 323 side of the engaging convex portion 322 is formed substantially at right angles to the length direction of the band 11.

突起３３は、バンド１１（図３）の係合孔１１１の径と略同径の円柱形状とされ、ボタンユニット枠３１の底面にかしめ固定されている。なお、かしめ固定に限らず、突起３３は、例えばレーザ溶接などによってボタンユニット枠３１の底面に固定されていてもよい。この突起３３は、ボタンユニット枠３１の上面から突出しており、バンド１１に形成された複数の係合孔１１１の１つに挿入されるが、その高さはバンド１１の厚みと同じである必要はない。   The protrusion 33 has a columnar shape that is substantially the same diameter as the diameter of the engagement hole 111 of the band 11 (FIG. 3), and is fixed by caulking to the bottom surface of the button unit frame 31. The protrusion 33 may be fixed to the bottom surface of the button unit frame 31 by, for example, laser welding or the like without being limited to caulking. The protrusion 33 protrudes from the upper surface of the button unit frame 31 and is inserted into one of the plurality of engagement holes 111 formed in the band 11, but the height thereof needs to be the same as the thickness of the band 11. There is no.

〔３−３．第１部材のバンドへの取付〕
図８、図９は、第１取付部材２０およびボタンユニット３０の６時側バンド１１への取付態様を示す。このバンド１１の表面側には第１取付部材２０が配置され、腕に接触する側であるバンド１１の裏面側にはボタンユニット３０が配置され、これら第１取付部材２０とボタンユニット３０との間にバンド１１が介装される。なお、第１取付部材２０とボタンユニット３０とは、締結時のバンドの長さに応じて選択された所定の係合孔１１１の位置でバンド１１に取り付けられる。 [3-3. Attaching the first member to the band]
FIGS. 8 and 9 show how the first attachment member 20 and the button unit 30 are attached to the 6 o'clock side band 11. The first attachment member 20 is disposed on the front surface side of the band 11, and the button unit 30 is disposed on the back surface side of the band 11 that is in contact with the arm, and the first attachment member 20 and the button unit 30 are connected to each other. A band 11 is interposed between them. The first attachment member 20 and the button unit 30 are attached to the band 11 at a predetermined engagement hole 111 selected according to the length of the band at the time of fastening.

この第１取付部材２０およびボタンユニット３０をバンド１１に取り付ける際は、図８に示すように所定の係合孔１１１に突起３３を挿入し、両方のプッシュボタン３２１，３２１をバンド１１の幅方向内側に押し込んだ状態で側壁２１，２１間にボタンユニット３０を配置し、図９のように、側壁２１の開口部２１１からプッシュボタン３２１を突出させる。
ここで、バンド１１は第１取付部材２０とボタンユニット３０との間に挟まれており、第１取付部材２０とボタンユニット３０との間で突起３３が係合孔１１１に挿入されているため、突起３３は係合孔１１１から抜け出ず、第１取付部材２０およびボタンユニット３０に対するバンド１１の平面位置が決まる。すなわち、第１取付部材２０およびボタンユニット３０がバンド１１の所定位置に固定されることになる。 When the first attachment member 20 and the button unit 30 are attached to the band 11, as shown in FIG. 8, the protrusion 33 is inserted into the predetermined engagement hole 111, and both the push buttons 321 and 321 are placed in the width direction of the band 11. The button unit 30 is disposed between the side walls 21 and 21 while being pushed inward, and the push button 321 is projected from the opening 211 of the side wall 21 as shown in FIG.
Here, the band 11 is sandwiched between the first attachment member 20 and the button unit 30, and the protrusion 33 is inserted into the engagement hole 111 between the first attachment member 20 and the button unit 30. The projection 33 does not come out of the engagement hole 111, and the planar position of the band 11 with respect to the first attachment member 20 and the button unit 30 is determined. That is, the first attachment member 20 and the button unit 30 are fixed at predetermined positions on the band 11.

なお、第１取付部材２０およびボタンユニット３０のバンド１１への取付位置を調整する際には、プッシュボタン３２１，３２１を側壁２１，２１の内側に押し込んで開口部２１１から外す。そして、突起３３をバンド１１に形成された他の係合孔１１１に挿入してから、プッシュボタン３２１，３２１を押し込んで開口部２１１から突出させればよい。   When adjusting the mounting positions of the first mounting member 20 and the button unit 30 to the band 11, the push buttons 321 and 321 are pushed into the side walls 21 and 21 to be removed from the opening 211. Then, after the protrusion 33 is inserted into another engagement hole 111 formed in the band 11, the push buttons 321 and 321 may be pushed in and protrude from the opening 211.

〔４．第２部材の構成〕
次に、１２時側バンド１２（図３）に取り付けられる第２部材３Ｂの構成を説明する。
図１０は、第２部材３Ｂの分解斜視図である。第２部材３Ｂは、１２時側バンド１２に取り付けられる断面略コ字状の第２取付部材４０と、ばね棒５０とを有して構成されている。

〔５．中留によるバンドの締結操作〕
次に、図１２〜図１４を参照し、中留３でバンド１１，１２を締結し、時計１を腕（装着対象）に装着する操作について説明する。
図１２は、本実施形態に係る時計１の側面図であり、図１３は、６時側バンド１１を長さ方向（矢印方向）に沿ってスライドさせる状態を示す。これらの図１２、図１３に示すように、６時側バンド１１の端部を第２取付部材４０の連結部４２と１２時側バンド１２との間に挿通し、この６時側バンド１１の端部を引っ張ると、６時側バンド１１と１２時側バンド１２とが相対的に長さ方向反対側にスライドされる。この際、第２取付部材４０の連結部４２がガイドとなり、６時側バンド１１が第２取付部材４０の側壁４１，４１間でバンド１１の長手方向に沿って案内される。 [5. Band fastening operation by Nakadome)
Next, with reference to FIG. 12 to FIG. 14, an operation of fastening the bands 11 and 12 with the middle ring 3 and attaching the timepiece 1 to the arm (attachment target) will be described.
FIG. 12 is a side view of the timepiece 1 according to the present embodiment, and FIG. 13 shows a state in which the 6 o'clock side band 11 is slid along the length direction (arrow direction). As shown in FIGS. 12 and 13, the end of the 6 o'clock side band 11 is inserted between the connecting portion 42 of the second mounting member 40 and the 12 o'clock side band 12, When the end is pulled, the 6 o'clock side band 11 and the 12 o'clock side band 12 are slid relative to each other in the length direction. At this time, the connecting portion 42 of the second mounting member 40 serves as a guide, and the 6 o'clock side band 11 is guided between the side walls 41 and 41 of the second mounting member 40 along the longitudinal direction of the band 11.

このように６時側バンド１１を１２時側バンド１２に対してスライドさせていくと、第１部材３Ａと第２部材３Ｂとが近接し、図１４に示すように、ボタンユニット３０の係合凸部３２２が第２取付部材４０の側壁４１の係合凹部４１２に側壁４１の内側から係合し、バンド１１，１２は締結される。
ここで、６時側バンド１１のスライド操作により、係合凸部３２２の斜面３２２Ａが側壁４１に当たりバンド１１の長さ方向に作用する力の分力によって、係合凸部３２２がバンド１１の幅方向内側に引っ込むので、当該係合凸部３２２は側壁４１の係合凹部４１２に円滑に案内される。こうして係合凸部３２２が側壁４１の内側から係合凹部４１２に挿入されることで、バンド１１，１２が締結される。
このようにバンド１１，１２が締結された状態では、プッシュボタン３２１と係合凸部３２２との間の切欠３２３に第１取付部材２０の側壁２１の一部と、第２取付部材４０の側壁４１の一部とが収容されている。すなわち、切欠３２３の幅は、バンド１１，１２の長さ方向における開口部２１１の端縁から側壁２１の端縁までの寸法と、同じくバンド１１，１２の長さ方向における係合凹部４１２の端縁から側壁２１の端縁までの寸法との和よりも若干大きくなっている。
また、係合凸部３２２の立ち上がり部３２２Ｂがバンド１１の長さ方向に対して略直角とされているので、バンド１１，１２の長さ方向に引っ張り力が作用しても、係合凸部３２２が係合凹部４１２から外れにくい。 When the 6 o'clock side band 11 is slid with respect to the 12 o'clock side band 12, the first member 3A and the second member 3B come close to each other, and as shown in FIG. The convex portion 322 engages with the engaging concave portion 412 of the side wall 41 of the second mounting member 40 from the inside of the side wall 41, and the bands 11 and 12 are fastened.
Here, due to the sliding operation of the 6 o'clock side band 11, the inclined surface 322A of the engaging convex portion 322 hits the side wall 41, and the engaging convex portion 322 becomes the width of the band 11 by the force component acting in the length direction of the band 11. Since the engagement protrusion 322 is retracted inward in the direction, the engagement protrusion 322 is smoothly guided to the engagement recess 412 of the side wall 41. Thus, the bands 11 and 12 are fastened by inserting the engaging convex part 322 into the engaging concave part 412 from the inside of the side wall 41.
When the bands 11 and 12 are fastened in this way, a part of the side wall 21 of the first mounting member 20 and the side wall of the second mounting member 40 are formed in the notch 323 between the push button 321 and the engaging convex portion 322. 41 is accommodated. That is, the width of the notch 323 is the same as the dimension from the edge of the opening 211 to the edge of the side wall 21 in the length direction of the bands 11 and 12, and the end of the engagement recess 412 in the length direction of the bands 11 and 12. It is slightly larger than the sum of the dimension from the edge to the edge of the side wall 21.
Further, since the rising portion 322B of the engaging convex portion 322 is substantially perpendicular to the length direction of the band 11, even if a tensile force acts in the length direction of the bands 11, 12, the engaging convex portion 322 is unlikely to be detached from the engaging recess 412.

バンド１１，１２の締結を解除する際は、両方のプッシュボタン３２１，３２１をバンド１１の幅方向内側に向かって押し、バンド１１，１２を緩む方向にスライドさせる。プッシュボタン３２１，３２１の押圧操作に連動して係合凸部３２２，３２２がバンド１１の幅方向内側にそれぞれ引っ込み、係合凹部４１２から外れるため、第１部材３Ａと第２部材３Ｂとが離間する側にバンド１１，１２をスライドさせることが可能となる。なお、バンド１１、１２の剛性による引張り力が作用するため、プッシュボタン３２１、３２１を押すだけでバンド１１、１２を意図的に大きくスライドさせなくても、バンド１１、１２を取り外すことができる。   When releasing the fastening of the bands 11 and 12, both the push buttons 321 and 321 are pushed inward in the width direction of the band 11, and the bands 11 and 12 are slid in the loosening direction. The engaging protrusions 322 and 322 are retracted inward in the width direction of the band 11 in conjunction with the pressing operation of the push buttons 321 and 321 and are disengaged from the engaging recess 412, so that the first member 3 </ b> A and the second member 3 </ b> B are separated from each other. It becomes possible to slide the bands 11 and 12 to the side to be performed. In addition, since the tensile force by the rigidity of the bands 11 and 12 acts, the bands 11 and 12 can be removed even if the bands 11 and 12 are not intentionally slid largely only by pushing the push buttons 321 and 321.

〔６．本実施形態の効果〕

A protruding portion 814 that protrudes along the length direction of the band 11 is formed on the second member 8B side. A slope 814 </ b> A is formed on the lower surface of the projecting portion 814 in an oblique direction with respect to both the length direction of the band and the height direction of the side wall 81.

図２９は、第１部材８Ａおよび第２部材８Ｂの水平断面図である。図３０は、図２９におけるＡ−Ａ線矢視図である。なお、図２９は、第１取付部材８０およびボタンユニット９０が図２７のように一体に取り付けられた状態を示す。
ボタンユニット９０は、図２８、図２９に示すように、第１取付部材８０の側壁８１，８１間に配置されるボタンユニット枠９１と、ボタン部材９２，９２と、プッシュボタン３２１および係合凸部３２２の間に配置された回動ロックボタンとしての回動ロックボタン９４，９４と、ボタンユニット枠９１の底面に固定された突起３３（図２８参照）とを有している。 FIG. 29 is a horizontal sectional view of the first member 8A and the second member 8B. 30 is a view taken along the line AA in FIG. FIG. 29 shows a state where the first attachment member 80 and the button unit 90 are integrally attached as shown in FIG.
As shown in FIGS. 28 and 29, the button unit 90 includes a button unit frame 91 disposed between the side walls 81 and 81 of the first mounting member 80, button members 92 and 92, a push button 321 and an engaging projection. Rotation lock buttons 94, 94 as rotation lock buttons disposed between the portions 322, and a protrusion 33 (see FIG. 28) fixed to the bottom surface of the button unit frame 91.

ボタンユニット枠９１は、図２７、図２８に示すように、金属薄板を用いた曲げ加工により形成され、ばね棒９０１の周りに巻かれた巻回部９１１，９１１と、断面略矩形状のボタン保持部９１２と、ボタン保持部９１２のバンド長さ方向に沿った両方の端縁から腕側に段落ちし、バンド長さ方向に沿って延びた案内部９１３，９１３（図３０参照）とを有している。本実施形態の案内部９１３の長さは、バンド長さ方向におけるボタンユニット枠９１の寸法とほぼ同じとなっている。
ボタン保持部９１２の上面の端縁部の一部には、図２８、図２９に示すように底面側に折り曲げられたストッパ９１２Ａが形成され、このストッパ９１２Ａによってボタン部材９２および回動ロックボタン９４がボタンユニット枠９１に係止されている。なお、ボタン部材９２および回動ロックボタン９４のそれぞれの凹凸の一部がストッパ９１２Ａの裏側に隠れることにより、ストッパ９１２Ａはボタンユニット９０の外観に寄与する。 As shown in FIGS. 27 and 28, the button unit frame 91 is formed by bending using a thin metal plate, wound portions 911 and 911 wound around a spring bar 901, and a button having a substantially rectangular cross section. A holding portion 912, and guide portions 913, 913 (see FIG. 30), which are stepped down from both ends of the button holding portion 912 along the band length direction to the arm side and extend along the band length direction. Have. The length of the guide part 913 of this embodiment is substantially the same as the dimension of the button unit frame 91 in the band length direction.
As shown in FIGS. 28 and 29, a stopper 912A bent toward the bottom surface is formed on a part of the upper edge of the button holding portion 912, and the button member 92 and the rotation lock button 94 are formed by the stopper 912A. Is locked to the button unit frame 91. It should be noted that the stopper 912A contributes to the appearance of the button unit 90 because a part of the unevenness of the button member 92 and the rotation lock button 94 is hidden behind the stopper 912A.

ボタン部材９２は、図２９に示すように、段付き形状の切欠９２３の両側にプッシュボタン３２１と係合凸部３２２とを一体に有する板状の部材とされている。   As shown in FIG. 29, the button member 92 is a plate-like member integrally having a push button 321 and an engaging convex portion 322 on both sides of a stepped notch 923.

回動ロックボタン９４は、切欠９２３の形状に倣った形状の平板状の部材であり、圧縮コイルばね９５によってボタンユニット枠９１の開口の内側から外側に向かって付勢されている。この回動ロックボタン９４は、切欠９２３内に配置されることにより、ボタンユニット枠９１に係止されている。回動ロックボタン９４の先端部は第１取付部材８０の回動ロック凹部８１３に係合する。すなわち、第１取付部材８０とボタンユニット９０とは、回動ロック凹部８１３に回動ロックボタン９４が係合することによって一体に組み付けられている。
回動ロックボタン９４の先端部には、図３０に示すように、第１取付部材８０の側壁８１の高さ方向とバンド１１（図２７）の幅方向との両方に対して斜め方向となる斜面９４１が形成されている。 The rotation lock button 94 is a flat plate-like member that follows the shape of the notch 923, and is urged toward the outside from the inside of the opening of the button unit frame 91 by a compression coil spring 95. The rotation lock button 94 is engaged with the button unit frame 91 by being disposed in the notch 923. The tip of the rotation lock button 94 is engaged with the rotation lock recess 813 of the first attachment member 80. That is, the first attachment member 80 and the button unit 90 are assembled together by the rotation lock button 94 engaging with the rotation lock recess 813.
As shown in FIG. 30, the distal end portion of the rotation lock button 94 is inclined with respect to both the height direction of the side wall 81 of the first mounting member 80 and the width direction of the band 11 (FIG. 27). A slope 941 is formed.

ここで、切欠９２３内において回動ロックボタン９４とボタン部材９２との間には、バンドの幅方向における所定寸法の隙間Ｓが形成されている。ここで、隙間Ｓの寸法は、係合凸部３２２が第２取付部材１００の係合凹部４１２に係脱する際におけるボタンユニット枠９１に対するボタン部材９２の移動距離をＡ、回動ロックボタン９４が第１取付部材８０の回動ロック凹部８１３に係脱する際におけるボタンユニット枠９１に対するボタン部材９２の移動距離をＢとすると、少なくとも隙間Ｓの寸法分、ＡはＢよりも小さくなるように決められている。本実施形態の隙間Ｓの寸法は、移動距離をＡと略同じ寸法に決められている。   Here, a gap S having a predetermined dimension in the width direction of the band is formed between the rotation lock button 94 and the button member 92 in the notch 923. Here, the dimension of the gap S is such that the moving distance of the button member 92 relative to the button unit frame 91 when the engaging convex portion 322 engages with and disengages from the engaging concave portion 412 of the second mounting member 100 is A, and the rotation lock button 94. When the movement distance of the button member 92 relative to the button unit frame 91 when engaging / disengaging with the rotation lock recess 813 of the first mounting member 80 is B, at least the dimension of the gap S is set so that A is smaller than B. It has been decided. The dimension of the gap S in this embodiment is determined so that the moving distance is substantially the same as A.

なお、ボタン部材９２がコイルばね３２４のばね力に抗して押されていない状態では、コイルばね３２４のばね力により、係合凸部３２２はストッパ９１２Ａに当接していることが好ましい。また、回動ロックボタン９４がコイルばね９５のばね力に抗して押されていない状態では、コイルばね９５のばね力により、回動ロックボタン９４はストッパ９１２Ａに当接していることが好ましい。これらにより、ボタン部材９２および回動ロックボタン９４の遊びをなくすことができる。   In the state where the button member 92 is not pushed against the spring force of the coil spring 324, it is preferable that the engagement convex portion 322 is in contact with the stopper 912A by the spring force of the coil spring 324. In a state where the rotation lock button 94 is not pressed against the spring force of the coil spring 95, the rotation lock button 94 is preferably in contact with the stopper 912A by the spring force of the coil spring 95. Accordingly, play of the button member 92 and the rotation lock button 94 can be eliminated.

図３１は、第１部材８Ａを回動軸側から見た側面図である。押さえ部材９０２は、バンド１１（図２７）とボタンユニット９０との間に介装される本体９０２Ａと、ボタンユニット枠９１の巻回部９１１，９１１の間に配置さればね棒９０１の周りに巻かれた巻回部９０２Ｂとを有している。この押さえ部材９０２におけるバンドの幅方向両側の端部は上方に曲げられており、バンド１１を幅方向両側で押さえてバンド１１の厚み方向および幅方向への移動を規制する。この押さえ部材９０２により、第１取付部材８０の側壁８１，８１間の寸法よりも狭い幅のバンドを使用した際に生じやすいガタを防止できる。   FIG. 31 is a side view of the first member 8A viewed from the rotation shaft side. The holding member 902 is disposed between the main body 902A interposed between the band 11 (FIG. 27) and the button unit 90 and the winding portions 911 and 911 of the button unit frame 91, and is wound around the spring bar 901. And a wound portion 902B. The ends of the pressing member 902 on both sides in the width direction of the band are bent upward, and the band 11 is pressed on both sides in the width direction to restrict the movement of the band 11 in the thickness direction and the width direction. The holding member 902 can prevent looseness that is likely to occur when a band having a narrower width than the dimension between the side walls 81 of the first mounting member 80 is used.

バンドの長さ調整に際しての第１部材８Ａの操作について説明する。図２６のように組み付けた状態の第１取付部材８０とボタンユニット９０との間からバンド１１を取り外す際には、プッシュボタン３２１（図２９）をボタンユニット枠９１の内側に押し込んで回動ロック凹部８１３と回動ロックボタン９４との係合を解除する。このとき、プッシュボタン３２１を隙間Ｓの寸法を超える押し込み量で押し込むことにより、ボタン部材９２と回動ロックボタン９４とが当接してプッシュボタン３２１の押し込み操作に回動ロックボタン９４が連動するようになる。回動ロックボタン９４と回動ロック凹部８１３との係合が解除されるまでのプッシュボタン３２１の押し込み量は、前記各実施形態においてプッシュボタン３２１を側壁２１の内側に完全に押し込んで開口部２１１（図８等）から外す際のプッシュボタン３２１の押し込み量よりも小さい。
回動ロックボタン９４が回動ロック凹部８１３から外れたら、図２８のように、第１取付部材８０とボタンユニット９０とを相対的に回動させ、突起３３が挿通されるバンド１１の係合孔１１１を変更する。ここで、第１取付部材８０とボタンユニット９０とはばね棒９０１により連結されているため、前記各実施形態とは違ってバンド１１の取り外しの際に第１取付部材８０とボタンユニット９０とが分離しない。 The operation of the first member 8A when adjusting the length of the band will be described. When removing the band 11 from between the first mounting member 80 and the button unit 90 in the assembled state as shown in FIG. 26, the push button 321 (FIG. 29) is pushed into the button unit frame 91 to be locked in rotation. The engagement between the recess 813 and the rotation lock button 94 is released. At this time, by pushing the push button 321 with a pushing amount exceeding the dimension of the gap S, the button member 92 and the turning lock button 94 come into contact with each other so that the turning lock button 94 is interlocked with the pushing operation of the push button 321. become. The pushing amount of the push button 321 until the engagement between the rotation lock button 94 and the rotation lock recess 813 is released is determined by pushing the push button 321 completely into the side wall 21 in each of the embodiments. It is smaller than the pushing amount of the push button 321 when removed from (FIG. 8 etc.).
When the rotation lock button 94 is disengaged from the rotation lock recess 813, as shown in FIG. 28, the first mounting member 80 and the button unit 90 are relatively rotated to engage the band 11 through which the protrusion 33 is inserted. The hole 111 is changed. Here, since the first attachment member 80 and the button unit 90 are connected by the spring bar 901, unlike the above-described embodiments, the first attachment member 80 and the button unit 90 are removed when the band 11 is removed. Do not separate.

バンド１１の所望の係合孔１１１に突起３３が挿通されたら、第１取付部材８０とボタンユニット９０とを互いの近接方向に回動させる。この際、図３０に示す回動ロックボタン９４の斜面９４１に第１取付部材８０の側壁８１の下端８１５が当たり、この際の分力によって回動ロックボタン９４がボタンユニット枠９１の内側に一旦移動したのち、コイルばね９５（図２９）のばね力によって元の位置に復帰し、回動ロックボタン９４の先端部が回動ロック凹部８１３に挿入される。このとき、クリック感が得られ確実にロックできたことを認識できるので、取扱性が良好となる。   When the protrusion 33 is inserted into the desired engagement hole 111 of the band 11, the first attachment member 80 and the button unit 90 are rotated in the proximity directions. At this time, the lower end 815 of the side wall 81 of the first mounting member 80 hits the inclined surface 941 of the rotation lock button 94 shown in FIG. 30, and the rotation lock button 94 is temporarily placed inside the button unit frame 91 by the component force at this time. After the movement, the coil spring 95 (FIG. 29) returns to its original position by the spring force, and the tip of the rotation lock button 94 is inserted into the rotation lock recess 813. At this time, since a click feeling is obtained and it can be recognized that the locking has been achieved, the handling property is improved.

次に、本実施形態の第２部材８Ｂの特徴について説明する。第２部材８Ｂは、図２７〜図２９に示すように、第２取付部材１００と、ばね棒５０と、ばね棒５５とを有している。本実施形態の第２部材８Ｂは、第２取付部材１００が有する連結部１０２の位置と、１２時側バンド１２を第２取付部材１００に取り付けるためのばね棒５０とは別のばね棒５５を有する点とが前記各実施形態とは相違する。これらの点を除いて、第２部材８Ｂは前記各実施形態の第２部材３Ｂと略同様に形成されている。   Next, features of the second member 8B of the present embodiment will be described. As shown in FIGS. 27 to 29, the second member 8 </ b> B has a second attachment member 100, a spring bar 50, and a spring bar 55. The second member 8 </ b> B of the present embodiment includes a spring bar 55 that is different from the position of the connecting portion 102 of the second mounting member 100 and the spring bar 50 for mounting the 12 o'clock side band 12 to the second mounting member 100. It differs from each of the embodiments described above. Except for these points, the second member 8B is formed in substantially the same manner as the second member 3B of each of the above embodiments.

第２取付部材１００は、図２８、図２９に示すように、バンド１２の幅方向両側にそれぞれ設けられる側壁１０１，１０１と、これら側壁１０１，１０１に架設される連結部１０２とを有して断面略コ字状に形成されている。
側壁１０１には、図２８に示すように、ばね棒５０の端部が係止される孔４１１と、ばね棒５５の端部が係止される孔１０１Ａと、ボタンユニット９０の係合凸部３２２が挿入される係合凹部４１２と、第１部材８Ａ側からバンドの長さ方向に沿って窪む凹部１０１Ｂとが形成されている。凹部１０１Ｂの内周の一部には、第１取付部材８０の突出部８１４の斜面８１４Ａと同じ方向の斜面１０１Ｃが形成されている。 As shown in FIGS. 28 and 29, the second mounting member 100 includes side walls 101, 101 provided on both sides in the width direction of the band 12, and a connecting portion 102 installed on the side walls 101, 101. It is formed in a substantially U-shaped cross section.
As shown in FIG. 28, the side wall 101 has a hole 411 in which the end of the spring bar 50 is locked, a hole 101 A in which the end of the spring bar 55 is locked, and an engagement convex part of the button unit 90. An engaging recess 412 into which 322 is inserted and a recess 101B that is recessed from the first member 8A side along the length direction of the band are formed. A slope 101C in the same direction as the slope 814A of the protrusion 814 of the first mounting member 80 is formed on a part of the inner periphery of the recess 101B.

ばね棒５５は、図２９に示すように側壁１０１，１０１間に配置されたパイプ５５０に挿通されており、バンド１２の幅方向端縁位置においてばね棒５０と平行に設けられている。このばね棒５５がバンド１２の端縁を押さえることにより、第２取付部材１００がばね棒５０を中心とする任意の回動角度に保持される。このため、バンド締結時に６時側バンド１１を連結部１０２にくぐらせ易い。   As shown in FIG. 29, the spring bar 55 is inserted into a pipe 550 disposed between the side walls 101, 101, and is provided in parallel with the spring bar 50 at the edge position in the width direction of the band 12. When the spring bar 55 presses the edge of the band 12, the second mounting member 100 is held at an arbitrary rotation angle around the spring bar 50. For this reason, it is easy to pass the 6 o'clock side band 11 through the connecting portion 102 when the band is fastened.

第２取付部材１００の連結部１０２の端縁部１０２Ａは、図２８に示すように、バンド１２の長さ方向でばね棒５０の位置に対して第１部材８Ａとは反対側に位置している。
なお、本実施形態の端縁部１０２Ａはバンドの幅方向に沿って直線的に形成されており、端縁部１０２Ａの全体がばね棒５０の位置に対して第１部材８Ａとは反対側に位置しているが、これに限らず、端縁部１０２Ａの一部のみ、例えばバンド幅方向の両端部のみがばね棒５０の位置に対して第１部材８Ａとは反対側に位置していてもよい。 As shown in FIG. 28, the end edge portion 102A of the connecting portion 102 of the second mounting member 100 is located on the opposite side of the first member 8A with respect to the position of the spring bar 50 in the length direction of the band 12. Yes.
The end edge portion 102A of the present embodiment is formed linearly along the width direction of the band, and the entire end edge portion 102A is opposite to the first member 8A with respect to the position of the spring bar 50. However, the present invention is not limited to this, and only a part of the end edge portion 102A, for example, only both end portions in the bandwidth direction are located on the side opposite to the first member 8A with respect to the position of the spring bar 50. Also good.

本実施形態の中留８によるバンド１１，１２の締結操作は、第１実施形態の中留３による締結操作と略同様である。但し、図３２に示すように、６時側バンド１１を連結部１０２にくぐらせてその先端側を１２時側バンド１２に対して斜め上方側に移動させた際に、６時側バンド１１がばね棒５０に対して第１部材８Ａ側とは反対側の位置（位置Ｐ）で連結部１０２の端縁部１０２Ａに当接する。この際の分力は図３２の反時計回り方向（回転矢印方向）に働くため、連結部１０２にバンド１１をくぐらせ易い。仮に、連結部１０２の端縁部１０２Ａがばね棒５０の位置よりも第１部材８Ａ側の位置Ｑにあり、位置Ｑでバンド１１が連結部１０２に当接するとすれば、第２取付部材１００が回転矢印方向に回動してバンド１１のスライドを妨げてしまう。本実施形態では、連結部１０２の端縁部１０２Ａにバンド１１が引っ掛かることなく、連結部１０２によりガイドした状態でバンド１１を安定的にスライドさせることができる。   The fastening operation of the bands 11 and 12 by the middle ends 8 of this embodiment is substantially the same as the fastening operation by the middle ends 3 of the first embodiment. However, as shown in FIG. 32, when the 6 o'clock side band 11 is passed through the connecting portion 102 and its tip side is moved obliquely upward with respect to the 12 o'clock side band 12, the 6 o'clock side band 11 is The spring bar 50 is in contact with the end edge portion 102A of the connecting portion 102 at a position (position P) opposite to the first member 8A side. Since the component force at this time acts in the counterclockwise direction (rotation arrow direction) in FIG. 32, the band 11 is easily passed through the connecting portion 102. If the end edge portion 102A of the connecting portion 102 is located at the position Q on the first member 8A side with respect to the position of the spring bar 50, and the band 11 contacts the connecting portion 102 at the position Q, the second mounting member 100 Will rotate in the direction of the rotation arrow, preventing the band 11 from sliding. In the present embodiment, the band 11 can be stably slid while being guided by the connecting portion 102 without being caught by the end edge portion 102 </ b> A of the connecting portion 102.

また、図３２の状態からバンド１１，１２をさらにスライドさせると、第２取付部材１００の凹部１０１Ｂの斜面１０１Ｃと第１取付部材８０の突出部８１４の斜面８１４Ａとが当接する。この際の分力によって第２取付部材１００がボタンユニット９０の底面側に向かって押圧され、側壁１０１の下端がボタンユニット９０の案内部９１３に当接する。このような突出部８１４および凹部１０１Ｂ、そして案内部９１３により、第１取付部材８０と第２取付部材１００とのバンド厚み方向の相対位置が決まるので、係合凸部３２２と係合凹部４１２とを確実に係合させることが可能となる。   Further, when the bands 11 and 12 are further slid from the state of FIG. 32, the inclined surface 101C of the concave portion 101B of the second mounting member 100 and the inclined surface 814A of the protruding portion 814 of the first mounting member 80 abut. The second attachment member 100 is pressed toward the bottom surface of the button unit 90 by the component force at this time, and the lower end of the side wall 101 abuts on the guide portion 913 of the button unit 90. The relative positions of the first mounting member 80 and the second mounting member 100 in the band thickness direction are determined by the projecting portion 814, the concave portion 101B, and the guide portion 913. Therefore, the engaging convex portion 322 and the engaging concave portion 412 Can be reliably engaged.

ここで、係合凸部３２２が係合凹部４１２に係合する際、係合凸部３２２が一旦側壁８１の内側に移動するが、前述したようにボタン部材９２と回動ロックボタン９４との間には隙間Ｓ（図２９）が設けられているため、回動ロックボタン９４が移動しない。このため、第１取付部材８０とボタンユニット９０とが外れてしまうことはない。
また、バンド１１，１２の締結解除時にプッシュボタン３２１を押しても、隙間Ｓの間隔が詰められるだけで回動ロックボタン９４は移動しないので、やはり、第１取付部材８０とボタンユニット９０とが外れてしまうことはない。
なお、図２８に示すように、ボタンユニット枠９１におけるプッシュボタン３２１の下方の位置に案内部９１３が形成されているため、プッシュボタン３２１が不用意に押されてバンド１１，１２の締結が解除されてしまうことを防止できる。 Here, when the engaging convex portion 322 engages with the engaging concave portion 412, the engaging convex portion 322 temporarily moves inside the side wall 81. As described above, the button member 92 and the rotation lock button 94 Since the clearance S (FIG. 29) is provided between them, the rotation lock button 94 does not move. For this reason, the 1st attachment member 80 and the button unit 90 do not remove | deviate.
Further, even if the push button 321 is pressed when the bands 11 and 12 are released, the rotation lock button 94 does not move just by closing the gap S, so that the first mounting member 80 and the button unit 90 are detached. There is no end to it.
As shown in FIG. 28, since the guide portion 913 is formed at a position below the push button 321 in the button unit frame 91, the push button 321 is carelessly pushed and the fastening of the bands 11 and 12 is released. Can be prevented.

以上の本実施形態によれば、前記各実施形態で述べた効果と同様の効果に加えて、主に、次のような効果が得られる。
（７）第１取付部材８０とボタンユニット９０とがばね棒９０１により回動可能に連結されているため、第１取付部材８０とボタンユニット９０とが分離することなくバンド１１の長さを調整することができる。これにより、バンドの長さ調整がより一層容易となる。
また、第１取付部材８０とボタンユニット９０とがばね棒９０１により連結されていることにより、第１取付部材８０とボタンユニット９０との組み付けを回動操作によって容易に行うことができる。
なお、ボタン部材９２と回動ロックボタン９４との間に隙間Ｓが形成されていることにより、係合凸部３２２が第２取付部材１００の係合凹部４１２に係脱する際に回動ロックボタン９４が回動ロック凹部から外れず、バンド同士の締結、締結解除の操作時に第１取付部材８０とボタンユニット９０とのロック状態を維持できる。 According to the present embodiment described above, the following effects are mainly obtained in addition to the same effects as those described in the above embodiments.
