Description

この発明は、腕時計、洋服、鞄、バッグなどに用いられる連結体、それを備えたバンド、およびそれらを備えた時計に関する。 This invention relates to connectors for use with watches, clothing, bags, purses, etc., bands equipped with the connectors, and timepieces equipped with the connectors.

例えば、腕時計のバンドにおいては、特許文献１に記載されているように、腕時計ケースのバンド取付部に取り付けられるバンドの一端部に固定部材を第１ピン部材によって取り付け、この固定部材のフック部を腕時計ケースのバンド取付部に取り付けられた第２ピン部材に引っ掛けて、バンドの一端部をバンド取付部に引き寄せて取り付ける構造のものが知られている。 For example, in the case of a wristwatch band, as described in Patent Document 1, a structure is known in which a fixing member is attached to one end of the band that is attached to the band attachment portion of the wristwatch case by a first pin member, and the hook portion of this fixing member is hooked onto a second pin member that is attached to the band attachment portion of the wristwatch case, thereby drawing one end of the band to the band attachment portion and attaching it.

しかしながら、このような腕時計のバンドでは、固定部材のフック部をバンド取付部の第２ピン部材に引っ掛けて、バンドの一端部をバンド取付部に引き寄せて取り付ける構造であるかから、腕時計ケースのバンド取付部にバンドの一端部をガタつくことなく取り付けることができても、構造が複雑で、取付作業性が悪いという問題がある。 However, with this type of watch band, the hook portion of the fixing member is hooked onto the second pin member of the band attachment portion, and one end of the band is pulled to the band attachment portion for attachment. Although one end of the band can be attached to the band attachment portion of the watch case without rattling, the structure is complex and there are problems with poor attachment workability.

この発明が解決しようとする課題は、簡単な構造で、取付作業性が良く、且つガタツキを防ぐことができる連結体、それを備えたバンド、およびそれらを備えた時計を提供することである。 The problem that this invention aims to solve is to provide a connector that has a simple structure, is easy to install, and prevents rattling, a band that includes the connector, and a watch that includes the band and the watch.

以下、図１～図８を参照して、この発明を腕時計に適用した一実施形態について説明する。
この腕時計は、図１～図３に示すように、連結対象である腕時計ケース１と、この腕時計ケース１に連結される被連結対象である時計バンド２と、を備えている。腕時計ケース１は、上ケース１ａと下ケース１ｂとを備えている。 An embodiment in which the present invention is applied to a wristwatch will now be described with reference to FIGS.
1 to 3, this wristwatch comprises a wristwatch case 1, which is an object to be connected, and a watch band 2, which is an object to be connected to the wristwatch case 1. Wristwatch case 1 comprises an upper case 1a and a lower case 1b.

この腕時計ケース１の上側開口部、つまり上ケース１ａの上側開口部には、図１および図３に示すように、時計ガラス３がパッキン３ａを介して装着されている。この腕時計ケース１の下部、つまり下ケース１ｂの下部には、裏蓋４が防水リング４ａを介して取り付けられている。この腕時計ケース１の内部、つまり下ケース１ｂの内部には、時計モジュール（図示せず）が設けられている。 As shown in Figures 1 and 3, a watch crystal 3 is attached to the upper opening of the watch case 1, i.e., the upper opening of the upper case 1a, via a packing 3a. A back cover 4 is attached to the lower part of the watch case 1, i.e., the lower part of the lower case 1b, via a waterproof ring 4a. A watch module (not shown) is provided inside the watch case 1, i.e., inside the lower case 1b.

この腕時計ケース１の６時側と１２側、つまり下ケース１ｂの６時側と１２時側とには、図１～図３に示すように、時計バンド２が取り付けられるバンド取付部５がそれぞれ設けられている。これらバンド取付部５は、時計バンド２の一端部の後述する連結駒８が取り付けられるように構成されている。 As shown in Figures 1 to 3, on the 6 o'clock and 12 o'clock sides of the watch case 1, i.e., on the 6 o'clock and 12 o'clock sides of the lower case 1b, there are band attachment parts 5 to which the watch band 2 is attached. These band attachment parts 5 are configured so that a connecting piece 8 (described later) at one end of the watch band 2 can be attached.

すなわち、このバンド取付部５は、図１、図３および図４に示すように、時計バンド２の長手方向である駒連結方向と直交する幅方向の両側部に設けられた一対の取付アーム５ａを備えている。これら一対の取付アーム５ａは、これらの間の間隔が時計バンド２の連結駒８の幅方向の長さとほぼ同じ大きさで形成されている。また、これら一対の取付アーム５ａそれぞれには、取付孔５ｂが同一軸上に対応して設けられている。 That is, as shown in Figures 1, 3 and 4, the band attachment section 5 has a pair of attachment arms 5a provided on both sides in the width direction perpendicular to the link connecting direction, which is the longitudinal direction of the watch band 2. The pair of attachment arms 5a are formed so that the distance between them is approximately the same as the width direction length of the link 8 of the watch band 2. In addition, each of the pair of attachment arms 5a is provided with an attachment hole 5b corresponding to the same axis.

一方、時計バンド２は、図２および図３に示すように、バンド本体６と、このバンド本体６の一端部に設けられた連結駒８と、を備えている。バンド本体６は、複数のバンド駒６ａを複数のピン部材７によって順次連結した構造になっている。この場合、複数のバンド駒６ａそれぞれは、一端部に連結凹部が設けられ、他端部に連結凸部が設けられ、連結凸部が隣接する他のバンド駒６ａの連結凹部に配置され、この状態でピン部材７によって連結されるように構成されている。 On the other hand, as shown in Figures 2 and 3, the watch band 2 comprises a band body 6 and a connecting piece 8 provided at one end of the band body 6. The band body 6 is structured such that a number of band links 6a are sequentially connected by a number of pin members 7. In this case, each of the multiple band links 6a is provided with a connecting recess at one end and a connecting protrusion at the other end, and the connecting protrusion is arranged in the connecting recess of the adjacent other band link 6a, and is configured to be connected in this state by the pin member 7.

この時計バンド２の連結駒８は、図１～図３および図５に示すように、複数のバンド駒６ａが連結されたバンド本体６の一端部のバンド駒６ａに連結されて、腕時計ケース１のバンド取付部５に連結体１０によって取り付けられるように構成されている。すなわち、連結駒８は、バンド取付部５の一対の取付アーム５ａ間に配置される駒本体８ａと、この駒本体８ａに設けられてバンド取付部５から腕時計ケース１の外部に向けて突出する連結凸部８ｂと、を備えている。 As shown in Figures 1 to 3 and 5, the connecting piece 8 of this watch band 2 is connected to a band piece 6a at one end of a band main body 6 to which multiple band pieces 6a are connected, and is configured to be attached to the band attachment part 5 of the watch case 1 by a connector 10. That is, the connecting piece 8 comprises a link body 8a that is disposed between a pair of attachment arms 5a of the band attachment part 5, and a connecting protrusion 8b that is provided on the link body 8a and protrudes from the band attachment part 5 toward the outside of the watch case 1.

この連結駒８の駒本体８ａには、図４および図５に示すように、連結体１０が挿入して取り付けられる第１挿入孔８ｃが、時計バンド２の幅方向に貫通して設けられている。この第１挿入孔８ｃは、駒本体８ａがバンド取付部５の一対の取付アーム５ａの間に配置された際に、一対の取付アーム５ａの各取付孔５ｂと同一軸上で対応するように構成されている。 As shown in Figures 4 and 5, the link body 8a of the linking link 8 has a first insertion hole 8c through it in the width direction of the watch band 2, into which the linking body 10 is inserted and attached. When the link body 8a is placed between the pair of attachment arms 5a of the band attachment section 5, the first insertion hole 8c is configured to correspond on the same axis to each of the attachment holes 5b of the pair of attachment arms 5a.

この場合、第１挿入孔８ｃは、図４および図５に示すように、内径が一対の取付アーム５ａの各取付孔５ｂの各内径よりも大きく形成されている。また、腕時計ケース１側に位置する駒本体８ａの先端面は、これに対向する腕時計ケース１の外周面と同じ形状で湾曲している。これにより、駒本体８ａは、バンド取付部５の一対の取付アーム５ａの間に配置された際に、駒本体８ａの先端面が腕時計ケース１の外周面に密接するように形成されている。 In this case, as shown in Figures 4 and 5, the first insertion hole 8c is formed with an inner diameter larger than the inner diameter of each of the mounting holes 5b of the pair of mounting arms 5a. In addition, the tip surface of the link body 8a located on the watch case 1 side is curved in the same shape as the outer peripheral surface of the watch case 1 that faces it. As a result, when the link body 8a is placed between the pair of mounting arms 5a of the band attachment part 5, the tip surface of the link body 8a is formed so that it is in close contact with the outer peripheral surface of the watch case 1.

また、この連結駒８の連結凸部８ｂは、図１～図３および図５に示すように、時計バンド２の長手方向と直交する幅方向の長さが駒本体８ａの幅方向の長さよりも短く、且つ連結駒８に隣接するバンド駒６ａの連結凹部内における幅方向の長さ（間隔）とほぼ同じ長さに形成されている。また、この連結凸部８ｂは、時計バンド２の長手方向の長さ（突出長さ）が連結駒８に隣接するバンド駒６ａの連結凹部における時計バンド２の長手方向の長さとほぼ同じ長さに形成されている。 As shown in Figures 1 to 3 and 5, the connecting protrusion 8b of the connecting piece 8 is formed so that its widthwise length perpendicular to the longitudinal direction of the watch band 2 is shorter than the widthwise length of the link body 8a, and is approximately the same length as the widthwise length (spacing) of the connecting recess of the band piece 6a adjacent to the connecting piece 8. The connecting protrusion 8b is also formed so that its length (protruding length) in the longitudinal direction of the watch band 2 is approximately the same as the length of the watch band 2 in the connecting recess of the band piece 6a adjacent to the connecting piece 8.

この場合、連結駒８の連結凸部８ｂには、図１～図３および図５に示すように、ピン部材７が挿入する第２挿入孔８ｄが、時計バンド２の幅方向に貫通して設けられている。これにより、連結駒８は、連結凸部８ｂが隣接するバンド駒６ａの連結凹部に配置された状態で、ピン部材７が連結凸部８ｂの第２挿入孔８ｄに挿入され、この挿入されたピン部材７の両端部がバンド駒６ａの連結凹部における両側部の連結孔６ｂに挿入して、隣接するバンド駒６ａに取り付けられるように構成されている。 In this case, as shown in Figures 1 to 3 and 5, the connecting protrusion 8b of the connecting piece 8 has a second insertion hole 8d into which the pin member 7 is inserted, which penetrates the width direction of the watch band 2. As a result, the connecting piece 8 is configured so that with the connecting protrusion 8b positioned in the connecting recess of the adjacent band piece 6a, the pin member 7 is inserted into the second insertion hole 8d of the connecting protrusion 8b, and both ends of the inserted pin member 7 are inserted into the connecting holes 6b on both sides of the connecting recess of the band piece 6a, and attached to the adjacent band piece 6a.

ところで、連結体１０は、図１～図４および図６に示すように、ばね棒であり、時計バンド２の連結駒８の第１挿入孔８ｃに挿入されて取り付けられる筒状部材であるパイプ１１と、このパイプ１１内に配置されたばね部材１２と、パイプ１１内における両側部に出没方向にスライド可能に配置された一対のスライド部材１３と、これら一対のスライド部材１３をパイプ１１の軸方向にスライドさせると共にパイプ１１の中心軸を中心に回転させる操作部材である一対の操作レバー１４と、を備えている。 As shown in Figures 1 to 4 and 6, the connector 10 is a spring bar, and includes a pipe 11, which is a cylindrical member that is inserted into and attached to the first insertion hole 8c of the connector 8 of the watch band 2, a spring member 12 arranged inside the pipe 11, a pair of slide members 13 arranged on both sides inside the pipe 11 so as to be slidable in the retractable direction, and a pair of operating levers 14, which are operating members that slide the pair of slide members 13 in the axial direction of the pipe 11 and rotate them around the central axis of the pipe 11.

これにより、連結体１０は、図４および図６に示すように、一対のスライド部材１３がばね部材１２のばね力によってパイプ１１の両端部から外部に向けて押し出されるように構成されている。この場合、パイプ１１は、その外径が時計バンド２の連結駒８の第１挿入孔８ｃの内径と同じ大きさに形成されている。また、このパイプ１１は、軸方向の長さが、連結駒８の連結凸部８ｂの幅方向の長さよりも長く、且つ駒本体８ａの幅方向の長さと同じか、それよりも少し短い長さで形成されている。 As a result, the connecting body 10 is configured so that the pair of slide members 13 are pushed outward from both ends of the pipe 11 by the spring force of the spring member 12, as shown in Figures 4 and 6. In this case, the pipe 11 is formed so that its outer diameter is the same as the inner diameter of the first insertion hole 8c of the connecting piece 8 of the watch band 2. In addition, the pipe 11 is formed so that its axial length is longer than the widthwise length of the connecting protrusion 8b of the connecting piece 8, and is the same as or slightly shorter than the widthwise length of the piece main body 8a.

このパイプ１１の両端部には、図４および図６に示すように、一対のスライド部材１３がパイプ１１内から抜け出すのを防ぐための抜止め部１１ａがそれぞれカシメ加工によって設けられている。これら抜止め部１１ａは、内径がパイプ１１の内径よりも小さく、且つバンド取付部５の一対の取付アーム５ａの各取付孔５ｂの内径とほぼ同じ大きさで形成されている。また、このパイプ１１は、連結駒８の第１挿入孔８ｃに挿入された際に、両側部が連結駒８の駒本体８ａの両側部に設けられた切欠き部１５内に配置されるように構成されている。 As shown in Figures 4 and 6, both ends of the pipe 11 are provided with stopper sections 11a by crimping to prevent the pair of slide members 13 from slipping out of the pipe 11. The inside diameter of these stopper sections 11a is smaller than the inside diameter of the pipe 11 and is formed to be approximately the same size as the inside diameter of each mounting hole 5b of the pair of mounting arms 5a of the band mounting part 5. In addition, when the pipe 11 is inserted into the first insertion hole 8c of the connecting piece 8, both sides are arranged in the notches 15 provided on both sides of the link body 8a of the connecting piece 8.

すなわち、パイプ１１は、図３および図４に示すように、両側部が駒本体８ａの両側部の各切欠き部１５内に配置された際に、バンド取付部５の下側つまり時計バンド２の連結駒８における駒本体８ａの下側に露出するように構成されている。この場合、切欠き部１５は、操作レバー１４をパイプ１１の軸方向にスライドさせると共に、パイプ１１の中心軸を中心に操作レバー１４を回転させるためのものである。 In other words, as shown in Figures 3 and 4, when both sides of the pipe 11 are placed in the respective notches 15 on both sides of the link body 8a, the pipe 11 is configured to be exposed below the band attachment part 5, i.e., below the link body 8a of the connecting link 8 of the watch band 2. In this case, the notch 15 is for sliding the operating lever 14 in the axial direction of the pipe 11 and for rotating the operating lever 14 around the central axis of the pipe 11.

すなわち、この切欠き部１５は、図３～図５に示すように、連結駒８の連結凸部８ｂの両側に突出した駒本体８ａの両側部にそれぞれ設けられている。つまり、この切欠き部１５は、駒本体８ａの両側部において、駒本体８ａの下側と連結凸部８ｂ側と駒本体８ａの両端側との３方向に開放されて形成されている。 That is, as shown in Figures 3 to 5, the notches 15 are provided on both sides of the piece body 8a that protrude on both sides of the connecting protrusion 8b of the connecting piece 8. In other words, the notches 15 are formed on both sides of the piece body 8a, opening in three directions: the lower side of the piece body 8a, the connecting protrusion 8b side, and both end sides of the piece body 8a.

ばね部材１２は、図４および図６に示すように、コイルばねであり、その外径がパイプ１１の内径よりも少し小さく形成され、伸縮方向の長さ、つまり軸方向の長さがパイプ１１内に配置された一対のスライド部材１３間の長さよりも長く形成されている。これにより、ばね部材１２は、両端部が一対のスライド部材１３の各内端面に弾接して一対のスライド部材１３をパイプ１１の内部から外部に向けて押し出す方向に付勢するように構成されている。 As shown in Figures 4 and 6, the spring member 12 is a coil spring whose outer diameter is slightly smaller than the inner diameter of the pipe 11 and whose length in the expansion and contraction direction, i.e., its axial length, is longer than the length between the pair of slide members 13 arranged inside the pipe 11. As a result, the spring member 12 is configured so that both ends elastically contact the inner end faces of the pair of slide members 13, urging the pair of slide members 13 in a direction that pushes them from the inside of the pipe 11 to the outside.

一対のスライド部材１３それぞれは、図４および図６に示すように、大径部１３ａと小径部１３ｂとを備え、これらがステンレスなどの金属によって形成されている。大径部１３ａは、パイプ１１の内部にスライド可能に配置されている。この大径部１３ａは、その外径がパイプ１１の内径よりも少し小さく形成され、軸方向の長さがパイプ１１の軸方向の長さの１/５程度の長さに形成されている。 As shown in Figures 4 and 6, each of the pair of slide members 13 has a large diameter portion 13a and a small diameter portion 13b, which are made of a metal such as stainless steel. The large diameter portion 13a is slidably disposed inside the pipe 11. The outside diameter of this large diameter portion 13a is formed to be slightly smaller than the inside diameter of the pipe 11, and the axial length is formed to be approximately 1/5 of the axial length of the pipe 11.

この大径部１３ａは、図４および図６に示すように、パイプ１１内の両側にそれぞれ配置されてばね部材１２によって押し出される方向に付勢された際に、小径部１３ｂとの境界に位置する段差部１３ｃの段差面がパイプ１１の抜止め部１１ａに当接して、パイプ１１の外部に抜け出さないように構成されている。 As shown in Figures 4 and 6, the large diameter portion 13a is arranged on both sides of the pipe 11, and when it is biased in the pushing direction by the spring member 12, the step surface of the step portion 13c located at the boundary with the small diameter portion 13b abuts against the retaining portion 11a of the pipe 11, so that it does not slip out to the outside of the pipe 11.

また、スライド部材１３の小径部１３ｂは、図４および図６に示すように、一対の大径部１３ａの段差部１３ｃにそれぞれ一体に設けられている。これら小径部１３ｂは、パイプ１１の両側の端部からパイプ１１の外部に向けて出没可能に突出して、バンド取付部５の一対の取付アーム５ａの各取付孔５ｂにそれぞれ同一軸上で挿入するように構成されている。 As shown in Figures 4 and 6, the small diameter portions 13b of the slide member 13 are integrally provided on the step portions 13c of the pair of large diameter portions 13a. These small diameter portions 13b protrude from both ends of the pipe 11 toward the outside of the pipe 11 and are configured to be inserted coaxially into the respective mounting holes 5b of the pair of mounting arms 5a of the band mounting portion 5.

すなわち、この小径部１３ｂは、図４および図６に示すように、その外径が大径部１３ａの外径よりも小さく、且つ一対の取付アーム５ａの各取付孔５ｂの内径およびパイプ１１の抜止め部１１ａの内径とほぼ同じか、それよりも少し小さい大きさで形成されている。また、この小径部１３ｂは、その軸方向の長さが大径部１３ａの軸方向の長さの約１/２の長さで、一対の取付アーム５ａにおける各取付孔５ｂの軸方向の長さと同じか、それよりも少し短い長さで形成されている。 That is, as shown in Figures 4 and 6, the small diameter portion 13b is formed with an outer diameter smaller than that of the large diameter portion 13a, and is approximately the same as or slightly smaller than the inner diameter of each mounting hole 5b of the pair of mounting arms 5a and the inner diameter of the retaining portion 11a of the pipe 11. Also, the small diameter portion 13b is formed with an axial length that is approximately 1/2 the axial length of the large diameter portion 13a, and is the same as or slightly shorter than the axial length of each mounting hole 5b in the pair of mounting arms 5a.

これにより、小径部１３ｂは、図４および図６に示すように、ばね部材１２のばね力によって大径部１３ａがパイプ１１の外部に向けて押された際に、パイプ１１の外部に押し出されて、腕時計ケース１のバンド取付部５における一対の取付アーム５ａの各取付孔５ｂに挿入するように構成されている。また、この小径部１３ｂは、ばね部材１２のばね力に抗して大径部１３ａがスライドした際に、一対の取付アーム５ａの各取付孔５ｂから抜け出して、パイプ１１の内部に押し込まれるように構成されている。 As a result, as shown in Figures 4 and 6, when the large diameter portion 13a is pushed toward the outside of the pipe 11 by the spring force of the spring member 12, the small diameter portion 13b is pushed out to the outside of the pipe 11 and inserted into each of the mounting holes 5b of the pair of mounting arms 5a in the band mounting portion 5 of the watch case 1. Also, when the large diameter portion 13a slides against the spring force of the spring member 12, the small diameter portion 13b is configured to slip out of each of the mounting holes 5b of the pair of mounting arms 5a and be pushed into the inside of the pipe 11.

また、これら一対のスライド部材１３の各大径部１３ａには、図４および図６に示すように、一対の操作レバー１４がパイプ１１の両側部に設けられた各第１開口部１１ｂを通してそれぞれ取り付けられている。これら操作レバー１４は、一対のスライド部材１３をそれぞれパイプ１１の内部において、ばね部材１２のばね力に抗して軸方向にスライドさせると共にパイプ１１の中心軸を中心に一対のスライド部材１３を回転させるように構成されている。 As shown in Figures 4 and 6, a pair of operating levers 14 are attached to the large diameter portions 13a of the pair of slide members 13 through the first openings 11b provided on both sides of the pipe 11. These operating levers 14 are configured to slide the pair of slide members 13 in the axial direction inside the pipe 11 against the spring force of the spring member 12 and to rotate the pair of slide members 13 around the central axis of the pipe 11.

すなわち、これら操作レバー１４それぞれは、図４および図６に示すように、頭部１４ａと軸部１４ｂとを備え、これらがステンレスなどの金属によって形成されている。これら操作レバー１４は、各軸部１４ｂがパイプ１１の各第１開口部１１ｂを通して各大径部１３ａの貫通孔１３ｄに取り付けられるように構成されている。この場合、軸部１４ｂは、ねじ軸で貫通孔１３ｄのねじ孔に螺合させて取り付けられていても良く、またレーザ光線などの溶接によって貫通孔１３ｄ内に取り付けられていても良い。 That is, as shown in Figs. 4 and 6, each of these operating levers 14 has a head 14a and a shaft 14b, which are made of a metal such as stainless steel. These operating levers 14 are configured so that each shaft 14b is attached to the through hole 13d of each large diameter portion 13a through each first opening 11b of the pipe 11. In this case, the shaft 14b may be attached by screwing into the threaded hole of the through hole 13d with a screw shaft, or may be attached inside the through hole 13d by welding with a laser beam or the like.

この場合、第１開口部１１ｂは、図６（ａ）および図６（ｂ）に示すように、長孔であり、パイプ１１の軸方向の長さがスライド部材１３の小径部１３ｂの軸方向の長さよりも長く、且つスライド部材１３の大径部１３ａの軸方向の長さよりも短い長さで形成されている。また、この第１開口部１１ｂは、パイプ１１の軸方向と直交する幅方向の長さが、操作レバー１４の軸部１４ｂの軸径と同じか、それよりも少し長く形成されている。 In this case, as shown in Figures 6(a) and 6(b), the first opening 11b is an elongated hole, and is formed such that the axial length of the pipe 11 is longer than the axial length of the small diameter portion 13b of the slide member 13, and shorter than the axial length of the large diameter portion 13a of the slide member 13. In addition, the length of this first opening 11b in the width direction perpendicular to the axial direction of the pipe 11 is the same as or slightly longer than the shaft diameter of the shaft portion 14b of the operating lever 14.

ところで、この連結体１０は、図２～図４、および図６に示すように、操作レバー１４の回転操作に応じて、時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し付ける押付部１６を備えている。この押付部１６は、半球形状に形成され、操作レバー１４の軸部１４ｂがスライド部材１３の大径部１３ａの貫通孔１３ｄを貫通した先端部に突出して設けられている。 As shown in Figures 2 to 4 and 6, the connecting body 10 is provided with a pressing portion 16 that presses the connecting piece 8 of the watch band 2 against the band attachment portion 5 of the watch case 1 in response to the rotation of the operating lever 14. The pressing portion 16 is formed in a semi-spherical shape and is provided so as to protrude from the tip end where the shaft portion 14b of the operating lever 14 penetrates the through hole 13d of the large diameter portion 13a of the slide member 13.

また、この押付部１６は、その表面が滑り性を有するポリアセタールなどの合成樹脂でコーティングされることが望ましい。この場合、パイプ１１には、図４および図６に示すように、押付部１６がスライド可能に挿入する第２開口部１１ｃが第１開口部１１ｂに対応して設けられている。この第２開口部１１ｃは、第１開口部１１ｂと同じ長さで同じ形状の長孔に形成されている。 The pressing portion 16 is preferably coated with a synthetic resin such as polyacetal, which has a slippery surface. In this case, as shown in Figs. 4 and 6, the pipe 11 is provided with a second opening 11c corresponding to the first opening 11b, into which the pressing portion 16 is slidably inserted. The second opening 11c is formed as an elongated hole of the same length and shape as the first opening 11b.

一方、時計バンド２の連結駒８の両側部に設けられた各切欠き部１５には、図１～図５に示すように、操作レバー１４を収納する収納部１５ａと、操作レバー１４の回転操作に応じて押付部１６が押し付けられて腕時計ケース１のバンド取付部５に時計バンド２の連結駒８を押し当てるカム部１５ｂと、が設けられている。 On the other hand, as shown in Figures 1 to 5, each cutout 15 on both sides of the connecting piece 8 of the watch band 2 is provided with a storage section 15a for storing the operating lever 14, and a cam section 15b against which the pressing section 16 is pressed in response to the rotation of the operating lever 14, pressing the connecting piece 8 of the watch band 2 against the band attachment section 5 of the watch case 1.

収納部１５ａは、図３および図５に示すように、連結駒８の両側部に設けられた各切欠き部１５の領域内の凹部であり、連結駒８の第１挿入孔８ｃを中心とするほぼ扇形状に形成されている。これにより、収納部１５ａは、図３に示すように、操作レバー１４の頭部１４ａが連結駒８の下側に突出した状態で、操作レバー１４の軸部１４ｂが図３において斜め上側に向けて反時計回り方向（矢印Ｘ方向）に回転した際に、図８に示すように、操作レバー１４を収納するように構成されている。 As shown in Figures 3 and 5, the storage section 15a is a recess in the area of each notch 15 provided on both sides of the connecting piece 8, and is formed in a substantially fan-shape centered on the first insertion hole 8c of the connecting piece 8. As a result, the storage section 15a is configured to store the operating lever 14 as shown in Figure 8 when the shaft 14b of the operating lever 14 rotates counterclockwise (in the direction of arrow X) diagonally upward in Figure 3 with the head 14a of the operating lever 14 protruding below the connecting piece 8 as shown in Figure 3.

この場合、収納部１５ａは、図８に示すように、操作レバー１４が矢印Ｘ方向に回転して収納された際に、余裕をもって操作レバー１４を収納するように構成されている。すなわち、この収納部１５ａは、操作レバー１４が収納された際に、手の指先によって操作レバー１４の頭部１４ａを操作させて収納部１５ａ内から引き出せる程度の隙間を有するように形成されている。 In this case, as shown in FIG. 8, the storage section 15a is configured to store the operating lever 14 with a sufficient margin when the operating lever 14 is rotated in the direction of the arrow X and stored. In other words, the storage section 15a is formed to have a gap large enough that the head 14a of the operating lever 14 can be operated with the fingertips of the hand and pulled out from within the storage section 15a when the operating lever 14 is stored.

カム部１５ｂは、図３および図５に示すように、連結駒８の両側部に設けられた各切欠き部１５における奥側上部の内壁面であり、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａに収納される際に、押付部１６が徐々に押し付けられる湾曲したカム面を備えている。すなわち、このカム部１５ｂは、図３に示すように、操作レバー１４の頭部１４ａが連結駒８の下側に突出した状態のときに、押付部１６の先端とカム部１５ｂの湾曲したカム面との間の隙間が広くなるように形成されている。 As shown in Figures 3 and 5, the cam portion 15b is the inner wall surface at the rear upper portion of each notch 15 provided on both sides of the connecting piece 8, and has a curved cam surface against which the pressing portion 16 is gradually pressed when the operating lever 14 rotates in the direction of the arrow X and is stored in the storage portion 15a. In other words, this cam portion 15b is formed so that the gap between the tip of the pressing portion 16 and the curved cam surface of the cam portion 15b becomes wider when the head portion 14a of the operating lever 14 protrudes below the connecting piece 8 as shown in Figure 3.

また、このカム部１５ｂは、図５および図８に示すように、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａに収納される際に、押付部１６の先端とカム部１５ｂのカム面との間の隙間が徐々に狭くなって、押付部１６の先端がカム部１５ｂのカム面に押し付けられるように形成されている。この場合、押付部１６は、スライド部材１３の大径部１３ａの外周面から突出する長さが、カム部１５ｂのカム面の形状に応じて、所定の長さに設定されている。 As shown in Figures 5 and 8, when the operating lever 14 rotates in the direction of the arrow X and is stored in the storage section 15a, the gap between the tip of the pressing section 16 and the cam surface of the cam section 15b gradually narrows, and the tip of the pressing section 16 is pressed against the cam surface of the cam section 15b. In this case, the length by which the pressing section 16 protrudes from the outer circumferential surface of the large diameter section 13a of the slide member 13 is set to a predetermined length according to the shape of the cam surface of the cam section 15b.

すなわち、押付部１６の突出した長さは、図３および図８に示すように、操作レバー１４の頭部１４ａが連結駒８の下側に突出した状態のときに、押付部１６の先端とカム部１５ｂの湾曲したカム面との間の隙間を広くし、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａに収納される際に、押付部１６の先端とカム部１５ｂのカム面との間の隙間を徐々に狭くしてカム部１５ｂのカム面に押し当てられる長さに設定されている。 That is, as shown in Figures 3 and 8, the protruding length of the pressing portion 16 is set to a length that widens the gap between the tip of the pressing portion 16 and the curved cam surface of the cam portion 15b when the head 14a of the operating lever 14 protrudes below the connecting piece 8, and gradually narrows the gap between the tip of the pressing portion 16 and the cam surface of the cam portion 15b when the operating lever 14 rotates in the direction of the arrow X and is stored in the storage portion 15a, so that the pressing portion 16 is pressed against the cam surface of the cam portion 15b.

この場合、図８に示すように、操作レバー１４が矢印Ｘ方向に回転してスライド部材１３の中心軸を中心に回転した際に、押付部１６は、スライド部材１３よりも腕時計ケース１のバンド取付部５側に位置し、押付部１６の先端がバンド取付部５側に向いてカム部１５ｂのカム面に押し当てられて、スライド部材１３の中心軸方向、つまり軸心方向に対してほぼ直交する方向で、時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し当てるように構成されている。 In this case, as shown in FIG. 8, when the operating lever 14 rotates in the direction of the arrow X around the central axis of the slide member 13, the pressing portion 16 is positioned closer to the band attachment portion 5 of the watch case 1 than the slide member 13, and the tip of the pressing portion 16 faces the band attachment portion 5 side and is pressed against the cam surface of the cam portion 15b, so that the connecting piece 8 of the watch band 2 is pressed against the band attachment portion 5 of the watch case 1 in the direction of the central axis of the slide member 13, i.e., in a direction approximately perpendicular to the axial direction.

これにより、押付部１６は、図３および図８に示すように、操作レバー１４の頭部１４ａが連結駒８の下側に突出した状態のときは、押付部１６の先端とカム部１５ｂの湾曲したカム面との間の隙間が広く、そして、操作レバー１４が矢印Ｘ方向に回転し、押付部１６の先端とカム部１５ｂのカム面との間の隙間を徐々に狭くし、操作レバー１４が収納部１５ａに収納された際に、押付部１６の先端が、腕時計ケース１のバンド取付部５側を向いて、カム部１５ｂのカム面に押し付けられ、時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し当てるように構成されている。 As a result, as shown in Figures 3 and 8, when the head 14a of the operating lever 14 protrudes below the connecting piece 8, the gap between the tip of the pressing part 16 and the curved cam surface of the cam part 15b is wide, and as the operating lever 14 rotates in the direction of the arrow X, the gap between the tip of the pressing part 16 and the cam surface of the cam part 15b gradually narrows, and when the operating lever 14 is stored in the storage part 15a, the tip of the pressing part 16 faces the band attachment part 5 of the watch case 1 and is pressed against the cam surface of the cam part 15b, pressing the connecting piece 8 of the watch band 2 against the band attachment part 5 of the watch case 1.

すなわち、時計バンド２の連結駒８は、図１～図３に示すように、駒本体８ａが腕時計ケース１のバンド取付部５における一対の取付アーム５ａの間に配置された状態で、押付部１６の先端がカム部１５ｂのカム面に押し付けられた際に、駒本体８ａの両側部が一対の取付アーム５ａの間に位置する腕時計ケース１の外周面に押し付けられて、駒本体８ａの先端面の全域が腕時計ケース１の外周面に押し当てられるように構成されている。 In other words, as shown in Figures 1 to 3, when the link body 8a of the watch band 2 is positioned between a pair of mounting arms 5a in the band mounting portion 5 of the watch case 1 and the tip of the pressing portion 16 is pressed against the cam surface of the cam portion 15b, both sides of the link body 8a are pressed against the outer peripheral surface of the watch case 1 located between the pair of mounting arms 5a, so that the entire tip surface of the link body 8a is pressed against the outer peripheral surface of the watch case 1.

この場合、時計バンド２の連結駒８は、図１～図３に示すように、押付部１６の先端がカム部１５ｂのカム面に押し付けられた際に、腕時計ケース１の外周面と同じ形状で湾曲した先端面の両側部が腕時計ケース１の外周面に押し付けられるので、駒本体８ａの先端面が腕時計ケース１の外周面に密接した状態で確実に押し付けられるように構成されている。 In this case, as shown in Figures 1 to 3, when the tip of the pressing portion 16 of the connecting link 8 of the watch band 2 is pressed against the cam surface of the cam portion 15b, both sides of the tip surface, which is curved in the same shape as the outer peripheral surface of the watch case 1, are pressed against the outer peripheral surface of the watch case 1, so that the tip surface of the link body 8a is reliably pressed against the outer peripheral surface of the watch case 1 in close contact therewith.

また、カム部１５ｂには、図５に示すように、押付部１６がカム部１５ｂに押し付けられた際に、押付部１６をロックするロック部１７が設けられている。このロック部１７は、カム部１５ｂのカム面に設けられた凹部であり、押付部１６がカム部１５ｂに最も強く押し付けられた際に、押付部１６の先端が係合することにより、操作レバー１４の不用意な回転を阻止するように形成されている。 In addition, as shown in FIG. 5, the cam portion 15b is provided with a lock portion 17 that locks the pressing portion 16 when the pressing portion 16 is pressed against the cam portion 15b. This lock portion 17 is a recess provided on the cam surface of the cam portion 15b, and is formed so that when the pressing portion 16 is pressed most strongly against the cam portion 15b, the tip of the pressing portion 16 engages with the lock portion 17, thereby preventing inadvertent rotation of the operating lever 14.

次に、このような腕時計ケース１に時計バンド２を取り付ける場合について説明する。
この場合には、まず、時計バンド２のバンド本体６の一端部に取り付けられる連結駒８に連結体１０を取り付ける。このときには、予め、連結体１０のパイプ１１内にばね部材１２を挿入させて、パイプ１１の両端部内に一対のスライド部材１３を挿入させる。この状態で、パイプ１１の両端部をカシメ加工によって抜止め部１１ａを形成する。 Next, a method for attaching the watch band 2 to such a wristwatch case 1 will be described.
In this case, first, the connector 10 is attached to the connector piece 8 attached to one end of the band body 6 of the watch band 2. At this time, the spring member 12 is inserted in advance into the pipe 11 of the connector 10, and a pair of slide members 13 are inserted into both ends of the pipe 11. In this state, both ends of the pipe 11 are crimped to form the retaining portions 11a.

これにより、パイプ１１内にばね部材１２と一対のスライド部材１３の各大径部１３ａとが配置された状態で、大径部１３ａの段差部１３ｃがパイプ１１の両端部の各抜止め部１１ａに当接する。このため、一対のスライド部材１３の各大径部１３ａがパイプ１１の両端部から抜け出すことなくパイプ１１の両側部内に配置されて、一対のスライド部材１３の各小径部１３ｂがパイプ１１の両端部から外部に突出して配置される。 As a result, with the spring member 12 and the large diameter portions 13a of the pair of slide members 13 arranged inside the pipe 11, the step portions 13c of the large diameter portions 13a come into contact with the respective retaining portions 11a at both ends of the pipe 11. Therefore, the large diameter portions 13a of the pair of slide members 13 are arranged inside both sides of the pipe 11 without slipping out from both ends of the pipe 11, and the small diameter portions 13b of the pair of slide members 13 are arranged to protrude outward from both ends of the pipe 11.

この状態で、パイプ１１を連結駒８の第１挿入孔８ｃに挿入させて、パイプ１１の両側部を連結駒８の両側部に設けられた各切欠き部１５内に配置させる。これにより、パイプ１１の両側部に設けられた各第１開口部１１ｂと各第２開口部１１ｃとが各切欠き部１５内に配置されて、各第１開口部１１ｂが各切欠き部１５内に露出する。 In this state, the pipe 11 is inserted into the first insertion hole 8c of the connecting piece 8, and both sides of the pipe 11 are positioned in the respective notches 15 provided on both sides of the connecting piece 8. As a result, the first openings 11b and the second openings 11c provided on both sides of the pipe 11 are positioned in the respective notches 15, and the first openings 11b are exposed in the respective notches 15.

この状態で、一対の操作レバー１４を一対のスライド部材１３に取り付ける。このときには、パイプ１１の第１開口部１１ｂを通して、操作レバー１４の軸部１４ｂをスライド部材１３の大径部１３ａに設けられた貫通孔１３ｄ内に挿入させ、この操作レバー１４の先端の押付部１６を第２開口部１１ｃから突出させる。この状態で、操作レバー１４がスライド部材１３の各大径部１３ａに取り付けられる。これにより、連結体１０が形成されて連結駒８に取り付けられる。 In this state, the pair of operating levers 14 are attached to the pair of slide members 13. At this time, the shaft portion 14b of the operating lever 14 is inserted into the through hole 13d provided in the large diameter portion 13a of the slide member 13 through the first opening 11b of the pipe 11, and the pressing portion 16 at the tip of the operating lever 14 is caused to protrude from the second opening 11c. In this state, the operating lever 14 is attached to each large diameter portion 13a of the slide member 13. As a result, the connecting body 10 is formed and attached to the connecting piece 8.

そして、連結駒８をバンド本体６に取り付けて、時計バンド２を形成する。このときには、予め、複数のバンド駒６ａを複数のピン部材７によって順次連結させて、バンド本体６を形成する。このバンド本体６の一端部のバンド駒６ａに連結駒８を取り付ける。このときには、まず、連結駒８の連結凸部８ｂをバンド駒６ａの連結凹部内に配置させる。 Then, the connecting piece 8 is attached to the band body 6 to form the watch band 2. At this time, the band body 6 is formed by first connecting multiple band pieces 6a in sequence with multiple pin members 7. The connecting piece 8 is attached to the band piece 6a at one end of the band body 6. At this time, first, the connecting protrusion 8b of the connecting piece 8 is placed in the connecting recess of the band piece 6a.

この状態で、ピン部材７をバンド駒６ａの連結凹部の両側の連結孔６ｂの一方から連結駒８の連結凸部８ｂの第２挿入孔８ｄに挿入させ、この挿入されたピン部材７をバンド駒６ａの連結凹部の両側の連結孔６ｂの他方に挿入させる。これにより、バンド本体６の一端部のバンド駒６ａに連結駒８が取り付けられ、時計バンド２が形成される。 In this state, the pin member 7 is inserted from one of the connecting holes 6b on both sides of the connecting recess of the band link 6a into the second insertion hole 8d of the connecting protrusion 8b of the connecting link 8, and the inserted pin member 7 is inserted into the other connecting hole 6b on both sides of the connecting recess of the band link 6a. This attaches the connecting link 8 to the band link 6a at one end of the band body 6, and the watch band 2 is formed.

そして、この時計バンド２を腕時計ケース１に取り付ける。このときには、まず、連結駒８に取り付けられた連結体１０の一対の操作レバー１４を、連結駒８の両側部の各切欠き部１５内において、ばね部材１２のばね力に抗して互いに接近する方向に移動させる。すると、一対の操作レバー１４の各軸部１４ｂがパイプ１１の両側に設けられた各第１開口部１１ｂに沿って移動すると共に、一対の操作レバー１４の各先端の押付部１６がパイプ１１の両側に設けられた各第２開口部１１ｃに沿って移動する。 Then, attach the watch band 2 to the watch case 1. At this time, first, move the pair of operating levers 14 of the connecting body 10 attached to the connecting piece 8 in a direction toward each other against the spring force of the spring member 12 in each of the notches 15 on both sides of the connecting piece 8. Then, the shafts 14b of the pair of operating levers 14 move along the first openings 11b on both sides of the pipe 11, and the pressing parts 16 at the tips of the pair of operating levers 14 move along the second openings 11c on both sides of the pipe 11.

これにより、パイプ１１の両側部内に配置された一対のスライド部材１３の各大径部１３ａがばね部材１２のばね力に抗して互いに接近する方向にスライドし、一対のスライド部材１３の各小径部１３ｂがパイプ１１の両端部内に引き込まれる。この状態で、連結駒８の駒本体８ａを腕時計ケース１のバンド取付部５の一対の取付アーム５ａ間に配置させる。そして、連結体１０の一対のスライド部材１３の各小径部１３ｂを一対の取付アーム５ａの各取付孔５ｂに対応させる。 As a result, the large diameter portions 13a of the pair of slide members 13 arranged on both sides of the pipe 11 slide toward each other against the spring force of the spring member 12, and the small diameter portions 13b of the pair of slide members 13 are pulled into both ends of the pipe 11. In this state, the link body 8a of the connecting link 8 is placed between the pair of mounting arms 5a of the band mounting portion 5 of the watch case 1. Then, the small diameter portions 13b of the pair of slide members 13 of the connecting body 10 are aligned with the mounting holes 5b of the pair of mounting arms 5a.

すると、一対のスライド部材１３の各大径部１３ａがばね部材１２のばね力によってパイプ１１の外部に向けて押し出される方向にスライドして、パイプ１１の両端部の各抜止め部１１ａに当接する。このときには、一対のスライド部材１３の各小径部１３ｂがパイプ１１の両端部から押し出されて一対の取付アーム５ａの各取付孔５ｂに挿入する。これにより、連結駒８が腕時計ケース１のバンド取付部５に取り付けられ、この連結駒８によって時計バンド２が腕時計ケース１に取り付けられる。 Then, the large diameter portions 13a of the pair of slide members 13 slide in a direction that pushes them outward from the pipe 11 due to the spring force of the spring member 12, and come into contact with the respective retaining portions 11a at both ends of the pipe 11. At this time, the small diameter portions 13b of the pair of slide members 13 are pushed out from both ends of the pipe 11 and inserted into the respective mounting holes 5b of the pair of mounting arms 5a. As a result, the connecting piece 8 is attached to the band mounting portion 5 of the watch case 1, and the watch band 2 is attached to the watch case 1 by this connecting piece 8.

この状態では、一対の操作レバー１４の各頭部１４ａが連結駒８の両側部に設けられた各切欠き部１５から連結駒８の下側に突出している。このため、パイプ１１の中心軸を中心に一対の操作レバー１４を斜め上方に向けて図３において反時計回り（矢印Ｘ方向）に回転させて、一対の操作レバー１４を各切欠き部１５の収納部１５ａ内に収納させる。これにより、一対の操作レバー１４が連結駒８の外部に突出することがないので、一対の操作レバー１４が邪魔になることがない。 In this state, the heads 14a of the pair of operating levers 14 protrude below the connecting piece 8 from the respective notches 15 provided on both sides of the connecting piece 8. Therefore, the pair of operating levers 14 are rotated diagonally upward counterclockwise (in the direction of arrow X) in FIG. 3 around the central axis of the pipe 11, and the pair of operating levers 14 are stored in the storage portions 15a of the respective notches 15. As a result, the pair of operating levers 14 do not protrude outside the connecting piece 8, and therefore do not get in the way.

また、このときには、一対の操作レバー１４の回転動作に伴って各押付部１６が各切欠き部１５のカム部１５ｂの湾曲したカム面に押し付けられて、連結駒８を腕時計ケース１のバンド取付部５に押し当てる。すなわち、操作レバー１４がパイプ１１の中心軸を中心に回転する際には、この操作レバー１４の回転動作に伴って操作レバー１４の先端の押付部１６がカム部１５ｂのカム面に徐々に押し付けられる。 At this time, as the pair of operating levers 14 rotate, each pressing portion 16 is pressed against the curved cam surface of the cam portion 15b of each cutout portion 15, pressing the connecting piece 8 against the band attachment portion 5 of the watch case 1. In other words, when the operating lever 14 rotates around the central axis of the pipe 11, the pressing portion 16 at the tip of the operating lever 14 is gradually pressed against the cam surface of the cam portion 15b as the operating lever 14 rotates.

この場合には、スライド部材１３の大径部１３ａの外周面から突出する押付部１６の長さが、カム部１５ｂのカム面の形状に応じて、所定の長さに設定されている。すなわち、押付部１６の突出した長さは、操作レバー１４の頭部１４ａが連結駒８の下側に突出した状態のときに、押付部１６の先端とカム部１５ｂの湾曲したカム面との間の隙間を広くし、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａに収納される際に、押付部１６の先端とカム部１５ｂのカム面との間の隙間を徐々に狭くしてカム部１５ｂのカム面に押し当てられる長さに設定されている。 In this case, the length of the pressing portion 16 protruding from the outer peripheral surface of the large diameter portion 13a of the slide member 13 is set to a predetermined length according to the shape of the cam surface of the cam portion 15b. In other words, the protruding length of the pressing portion 16 is set to a length that widens the gap between the tip of the pressing portion 16 and the curved cam surface of the cam portion 15b when the head portion 14a of the operating lever 14 protrudes below the connecting piece 8, and gradually narrows the gap between the tip of the pressing portion 16 and the cam surface of the cam portion 15b when the operating lever 14 rotates in the direction of the arrow X and is stored in the storage portion 15a, so that the pressing portion 16 is pressed against the cam surface of the cam portion 15b.

このため、操作レバー１４が回転する前の状態のときには、押付部１６の先端とカム部１５ｂのカム面との間の隙間が広く、操作レバー１４が回転して収納部１５ａに収納される際には、押付部１６の先端とカム部１５ｂのカム面との間の隙間が徐々に狭くなって、押付部１６の先端がカム部１５ｂのカム面に押し付けられる。 Before the operating lever 14 rotates, the gap between the tip of the pressing portion 16 and the cam surface of the cam portion 15b is wide, and when the operating lever 14 rotates and is stored in the storage portion 15a, the gap between the tip of the pressing portion 16 and the cam surface of the cam portion 15b gradually narrows, and the tip of the pressing portion 16 is pressed against the cam surface of the cam portion 15b.

そして、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａ内に収納された際には、押付部１６がスライド部材１３よりも腕時計ケース１のバンド取付部５側に位置し、押付部１６の先端が腕時計ケース１のバンド取付部５側を向いてカム部１５ｂの湾曲したカム面に最も強く押し付けられる。 When the operating lever 14 rotates in the direction of the arrow X and is stored in the storage section 15a, the pressing section 16 is positioned closer to the band attachment section 5 of the watch case 1 than the sliding member 13, and the tip of the pressing section 16 faces the band attachment section 5 of the watch case 1 and is pressed most strongly against the curved cam surface of the cam section 15b.

これにより、連結駒８が腕時計ケース１のバンド取付部５に確実に押し当てられる。このときには、時計バンド２の連結駒８の駒本体８ａが腕時計ケース１のバンド取付部５における一対の取付アーム５ａの間に配置された状態で、一対の押付部１６の各先端が連結体１０の各カム部１５ｂのカム面に押し付けられて、駒本体８ａの両側部が一対の取付アーム５ａの間に位置する腕時計ケース１の外周面に押し付けられる。 This ensures that the linking piece 8 is pressed securely against the band attachment portion 5 of the watch case 1. At this time, with the link body 8a of the linking piece 8 of the watch band 2 positioned between the pair of attachment arms 5a in the band attachment portion 5 of the watch case 1, the tips of the pair of pressing portions 16 are pressed against the cam surfaces of the cam portions 15b of the linking body 10, and both sides of the link body 8a are pressed against the outer peripheral surface of the watch case 1 located between the pair of attachment arms 5a.

このため、駒本体８ａの先端面の全域が腕時計ケース１の外周面に押し当てられるので、連結駒８の駒本体８ａの先端面がバンド取付部５の一対の取付アーム５ａ間に位置する腕時計ケース１の外面に押し当てられて密接する。この密接した状態で、時計バンド２が腕時計ケース１のバンド取付部５にガタツクことなく確実に取り付けられる。 As a result, the entire tip surface of the link body 8a is pressed against the outer circumferential surface of the watch case 1, so that the tip surface of the link body 8a of the connecting link 8 is pressed against and tightly attached to the outer surface of the watch case 1 located between the pair of mounting arms 5a of the band attachment section 5. In this tightly attached state, the watch band 2 is securely attached to the band attachment section 5 of the watch case 1 without any rattling.

このように、操作レバー１４が回転して収納部１５ａ内に収納された際には、押付部１６がカム部１５ｂのカム面に設けられたロック部１７にロックされる。すなわち、このロック部１７は、カム部１５ｂのカム面に設けられた凹部であり、操作レバー１４が収納部１５ａ内に収納されて押付部１６がカム部１５ｂのカム面に最も押し付けられた際に、押付部１６がロック部１７に係合してロックされる。これにより、操作レバー１４の不用意な回転が防げる。 In this way, when the operating lever 14 rotates and is stored in the storage section 15a, the pressing portion 16 is locked by the locking portion 17 provided on the cam surface of the cam portion 15b. In other words, this locking portion 17 is a recess provided on the cam surface of the cam portion 15b, and when the operating lever 14 is stored in the storage section 15a and the pressing portion 16 is pressed most against the cam surface of the cam portion 15b, the pressing portion 16 engages with the locking portion 17 and is locked. This prevents the operating lever 14 from rotating unintentionally.

次に、腕時計ケース１に取り付けられた時計バンド２を取り外して交換する場合について説明する。
この場合には、まず、パイプ１１の中心軸を中心に一対の操作レバー１４を矢印Ｘ方向と反対方向に回転させて、一対の操作レバー１４の各頭部１４ａを各切欠き部１５の収納部１５ａ内から引き出す。 Next, a case in which the watch band 2 attached to the wristwatch case 1 is removed and replaced will be described.
In this case, first, the pair of operating levers 14 are rotated in the direction opposite to the direction of arrow X around the central axis of the pipe 11, and the heads 14a of the pair of operating levers 14 are pulled out from within the storage portions 15a of the respective cutout portions 15.

このときには、操作レバー１４が収納部１５ａ内に余裕をもって収納されているので、手の指先によって操作レバー１４の頭部１４ａを操作して、パイプ１１の中心軸を中心に操作レバー１４を矢印Ｘ方向と反対方向に回転させることができる。これにより、操作レバー１４の頭部１４ａを収納部１５ａ内から容易に且つ良好に引き出せる。 At this time, the operating lever 14 is stored in the storage section 15a with ample space, so the head 14a of the operating lever 14 can be operated with the fingertips to rotate the operating lever 14 in the direction opposite to the direction of arrow X around the central axis of the pipe 11. This allows the head 14a of the operating lever 14 to be easily and satisfactorily pulled out from within the storage section 15a.

このようにして、一対の操作レバー１４が回転して各収納部１５ａ内から引き出される際には、操作レバー１４の先端の押付部１６がロック部１７から離脱して、ロック部１７によるロックが解除される。そして、押付部１６がカム部１５ｂのカム面に沿って移動し、押付部１６とカム部のカム面との間隔が徐々に広くなる。これにより、押付部１６によるカム部１５ｂのカム面に対する押し付けが解除され、腕時計ケース１のバンド取付部５に対する連結駒８の押し当てが解除される。 In this way, when the pair of operating levers 14 rotate and are pulled out from within each storage section 15a, the pressing section 16 at the tip of the operating lever 14 disengages from the locking section 17, and the locking by the locking section 17 is released. The pressing section 16 then moves along the cam surface of the cam section 15b, and the distance between the pressing section 16 and the cam surface of the cam section gradually increases. This releases the pressing section 16 from pressing against the cam surface of the cam section 15b, and releases the pressing of the connecting piece 8 against the band attachment section 5 of the watch case 1.

この状態で、連結駒８の両側部に設けられた各切欠き部１５内において、一対の操作レバー１４をばね部材１２のばね力に抗して互いに接近させる方向に移動させる。このときには、一対の操作レバー１４の各軸部１４ｂがパイプ１１の両側に設けられた各第１開口部１１ｂに沿って移動すると共に、一対の操作レバー１４の各先端の押付部１６がパイプ１１の両側に設けられた各第１開口部１１ｂに沿って移動する。 In this state, the pair of operating levers 14 are moved toward each other against the spring force of the spring member 12 within the respective cutouts 15 provided on both sides of the connecting piece 8. At this time, the respective shafts 14b of the pair of operating levers 14 move along the respective first openings 11b provided on both sides of the pipe 11, and the pressing portions 16 at the respective tips of the pair of operating levers 14 move along the respective first openings 11b provided on both sides of the pipe 11.

これにより、パイプ１１の両側部内に配置された一対のスライド部材１３の各大径部１３ａがばね部材１２のばね力に抗して互いに接近する方向にスライドし、一対のスライド部材１３の各小径部１３ｂが腕時計ケース１のバンド取付部５における一対の取付アーム５ａの各取付孔５ｂ内から抜け出して、パイプ１１の両端部内に引き込まれる。この状態で、連結駒８の駒本体８ａをバンド取付部５の一対の取付アーム５ａ間から取り外す。これにより、時計バンド２を腕時計ケース１から取り外して容易に交換することができる。 As a result, the large diameter portions 13a of the pair of slide members 13 arranged on both sides of the pipe 11 slide toward each other against the spring force of the spring member 12, and the small diameter portions 13b of the pair of slide members 13 slip out of the mounting holes 5b of the pair of mounting arms 5a in the band mounting portion 5 of the watch case 1 and are pulled into both ends of the pipe 11. In this state, the link body 8a of the connecting link 8 is removed from between the pair of mounting arms 5a of the band mounting portion 5. This allows the watch band 2 to be removed from the watch case 1 and easily replaced.

このように、この腕時計の連結体１０によれば、被連結対象である時計バンド２の連結駒８に取り付けられる筒状部材であるパイプ１１と、このパイプ１１の端部内に出没方向にスライド可能に設けられて連結対象である腕時計ケース１のバンド取付部５に連結されるスライド部材１３と、このスライド部材１３に設けられてスライド部材１３をスライドさせると共にパイプ１１の中心軸を中心に回転させる操作部材である操作レバー１４と、この操作レバー１４の回転動作に応じて時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し付ける押付部１６と、を備えていることにより、簡単な構造で、時計バンド２の取付作業性が良く、且つ腕時計ケース１に対する時計バンド２のガタツキを防ぐことができる。 In this way, this wristwatch connector 10 is equipped with a pipe 11, which is a cylindrical member attached to the connecting piece 8 of the watch band 2, which is the connected object; a slide member 13 that is slidably provided in the end of this pipe 11 in the direction of ingress and egress and is connected to the band attachment part 5 of the watch case 1, which is the connected object; an operating lever 14 that is provided on this slide member 13 and is an operating member that slides the slide member 13 and rotates it around the central axis of the pipe 11; and a pressing part 16 that presses the connecting piece 8 of the watch band 2 against the band attachment part 5 of the watch case 1 in response to the rotation of this operating lever 14. This makes it possible to easily attach the watch band 2 with a simple structure and prevent the watch band 2 from rattling relative to the watch case 1.

すなわち、この腕時計の連結体１０では、操作レバー１４の回転動作に応じて時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し付ける押付部１６を追加するだけであるから、構造が簡単で、部品点数の増加を少なく抑えることができると共に、操作レバー１４をパイプ１１の軸方向に移動操作させてスライド部材１３をスライドさせるだけで、時計バンド２を腕時計ケース１のバンド取付部５から容易に取り外すことができるので、時計バンド２の取付作業性が良い。 In other words, this wristwatch connecting body 10 only requires the addition of a pressing portion 16 that presses the connecting piece 8 of the watch band 2 against the band attachment portion 5 of the watch case 1 in response to the rotation of the operating lever 14, so the structure is simple and the increase in the number of parts can be kept to a minimum. In addition, the watch band 2 can be easily removed from the band attachment portion 5 of the watch case 1 by simply moving the operating lever 14 in the axial direction of the pipe 11 to slide the slide member 13, which makes it easy to attach the watch band 2.

また、この腕時計の連結体１０では、パイプ１１の中心軸を中心に操作レバー１４を回転操作するだけで、押付部１６が時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し当てることができるので、腕時計ケース１のバンド取付部５に時計バンド２の連結駒８をガタつくことなく確実に且つ良好に取り付けることができる。 In addition, with this wristwatch connector 10, simply by rotating the operating lever 14 around the central axis of the pipe 11, the pressing portion 16 can press the connecting piece 8 of the watch band 2 against the band attachment portion 5 of the wristwatch case 1, so that the connecting piece 8 of the watch band 2 can be securely and securely attached to the band attachment portion 5 of the wristwatch case 1 without any rattling.

この場合、この連結体１０では、操作レバー１４がスライド部材１３に軸方向と直交する方向に貫通して設けられ、押付部１６がスライド部材１３を貫通した操作レバー１４の先端に突出して設けられていることにより、押付部１６を備えていても、押付部１６を別部品として設ける必要がないので、部品点数が増加することがなく、簡単な構造で、押付部１６を容易に且つ良好に設けることができる。 In this case, in this connecting body 10, the operating lever 14 is provided penetrating the slide member 13 in a direction perpendicular to the axial direction, and the pressing portion 16 is provided protruding from the tip of the operating lever 14 that penetrates the slide member 13. Therefore, even if the pressing portion 16 is provided, it is not necessary to provide the pressing portion 16 as a separate part, so the number of parts does not increase, and the pressing portion 16 can be easily and satisfactorily provided with a simple structure.

また、この連結体１０では、被連結対象である時計バンド２の連結駒８に、操作レバー１４の回転操作に応じて押付部１６が徐々に押し付けられるカム部１５ｂが設けられていることにより、操作レバー１４を回転操作させた際に、押付部１６を連結駒８のカム部１５ｂのカム面に徐々に押し付けることができるので、腕時計ケース１のバンド取付部５に時計バンド２の連結駒８を確実に且つ良好に押し当てることができ、これにより腕時計ケース１に対する時計バンド２のガタツキを確実に防ぐことができる。 In addition, in this connecting body 10, the connecting piece 8 of the watch band 2, which is the connected object, is provided with a cam portion 15b against which the pressing portion 16 is gradually pressed in response to the rotation of the operating lever 14. Therefore, when the operating lever 14 is rotated, the pressing portion 16 can be gradually pressed against the cam surface of the cam portion 15b of the connecting piece 8, so that the connecting piece 8 of the watch band 2 can be reliably and satisfactorily pressed against the band attachment portion 5 of the watch case 1, thereby reliably preventing the watch band 2 from rattling relative to the watch case 1.

すなわち、この連結体１０では、操作レバー１４が回転する前の状態のときに、押付部１６とカム部１５ｂのカム面との間の隙間が広く、操作レバー１４が矢印Ｘ方向に回転して収納部１５ａに収納される際に、押付部１６とカム部１５ｂのカム面との間の隙間が徐々に狭くなり、操作レバー１４が矢印Ｘ方向に最も回転した際に、押付部１６をカム部１５ｂの湾曲したカム面に最も強く押し付けることができるので、連結駒８を腕時計ケース１のバンド取付部５に確実に押し当てることができる。 In other words, in this connecting body 10, before the operating lever 14 rotates, the gap between the pressing portion 16 and the cam surface of the cam portion 15b is wide, and when the operating lever 14 rotates in the direction of the arrow X and is stored in the storage portion 15a, the gap between the pressing portion 16 and the cam surface of the cam portion 15b gradually narrows, and when the operating lever 14 has rotated the most in the direction of the arrow X, the pressing portion 16 can be pressed most strongly against the curved cam surface of the cam portion 15b, so that the connecting piece 8 can be reliably pressed against the band attachment portion 5 of the watch case 1.

このため、この連結体１０では、連結駒８が腕時計ケース１のバンド取付部５に押し当てられた際に、連結駒８の駒本体８ａの先端面をバンド取付部５の一対の取付アーム５ａ間に位置する腕時計ケース１の外面に確実に押し当てて密接させることができるので、時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に確実に押し当てて取り付けることができ、これにより腕時計ケース１に対する時計バンド２のガタツキを確実に且つ良好に防ぐことができる。 For this reason, in this connecting body 10, when the connecting piece 8 is pressed against the band attachment portion 5 of the watch case 1, the tip surface of the link body 8a of the connecting piece 8 can be reliably pressed against and in close contact with the outer surface of the watch case 1 located between the pair of attachment arms 5a of the band attachment portion 5, so that the connecting piece 8 of the watch band 2 can be reliably pressed against and attached to the band attachment portion 5 of the watch case 1, thereby reliably and effectively preventing the watch band 2 from rattling relative to the watch case 1.

この場合、この連結体１０では、押付部１６がカム部１５ｂに押し付けられた際に、押付部１６をロックするロック部１７がカム部１５ｂに設けられていることにより、押付部１６をカム部１５ｂに押し付けた状態でロック部１７によってロックすることができるので、操作レバー１４の不用意な回転を阻止することができ、これにより時計バンド２の連結駒８を腕時計ケース１のバンド取付部５に押し当てた状態を確実に維持し続けることができる。 In this case, in this connecting body 10, the locking portion 17 that locks the pressing portion 16 when the pressing portion 16 is pressed against the cam portion 15b is provided on the cam portion 15b, so that the pressing portion 16 can be locked by the locking portion 17 while pressed against the cam portion 15b, preventing inadvertent rotation of the operating lever 14, and thus reliably maintaining the state in which the connecting piece 8 of the watch band 2 is pressed against the band attachment portion 5 of the watch case 1.

すなわち、この連結体１０では、ロック部１７がカム部１５ｂの湾曲したカム面に設けられた凹部であることにより、操作レバー１４が矢印Ｘ方向に最も回転して押付部１６がカム部１５ｂのカム面に最も強く押し付けられた際に、押付部１６をロック部１７に係合させることができるので、簡単な構造で、押付部１６をロック部１７で確実に且つ良好にロックすることができる。 In other words, in this connecting body 10, the locking portion 17 is a recess provided on the curved cam surface of the cam portion 15b, so that when the operating lever 14 rotates the most in the direction of the arrow X and the pressing portion 16 is pressed most strongly against the cam surface of the cam portion 15b, the pressing portion 16 can be engaged with the locking portion 17. This allows the pressing portion 16 to be reliably and satisfactorily locked by the locking portion 17 with a simple structure.

また、この連結体１０では、被連結対象である時計バンド２の連結駒８に、操作レバー１４を収納する収納部１５ａが設けられていることにより、操作レバー１４が邪魔にならないように、連結駒８の収納部１５ａ内に操作レバー１４を収納させることができる。すなわち、収納部１５ａは、連結駒８の両側部に設けられた各切欠き部１５の領域内に設けられているので、操作レバー１４を収納部１５ａ内に確実に且つ良好に収納させることができる。 In addition, in this connecting body 10, the connecting piece 8 of the watch band 2, which is the connected object, is provided with a storage section 15a for storing the operating lever 14, so that the operating lever 14 can be stored in the storage section 15a of the connecting piece 8 so that it does not get in the way. In other words, since the storage section 15a is provided within the area of each notch section 15 provided on both sides of the connecting piece 8, the operating lever 14 can be securely and satisfactorily stored in the storage section 15a.

さらに、この連結体１０では、スライド部材１３がパイプ１１の両端部内にそれぞれ配置されており、操作レバー１４がパイプ１１の両端部内に配置されたスライド部材１３にそれぞれ設けられていることにより、一対の操作レバー１４を回転操作させて一対の押付部１６を連結駒８の両側部に設けられた各カム部１５ｂにそれぞれ押し付けることができるので、連結駒８を腕時計ケース１のバンド取付部５に安定した状態で均等に押し当てることができる。 Furthermore, in this connecting body 10, the slide members 13 are disposed within both ends of the pipe 11, and the operating levers 14 are provided on the slide members 13 disposed within both ends of the pipe 11, so that the pair of operating levers 14 can be rotated to press the pair of pressing portions 16 against the cam portions 15b provided on both sides of the connecting piece 8, respectively, so that the connecting piece 8 can be pressed evenly against the band attachment portion 5 of the watch case 1 in a stable state.

また、この腕時計の時計バンド２によれば、バンド本体６の一端部のバンド駒６ａに連結駒８が取り付けられ、この連結駒８に連結体１０が取り付けられているので、この連結体１０の操作レバー１４をスライド操作させるだけで、腕時計ケース１のバンド取付部５に時計バンド２を簡単に且つ容易に取り付けることができると共に、時計バンド２を腕時計ケース１のバンド取付部５から簡単に且つ容易に取り外して交換することができる。 In addition, with the watch band 2 of this wristwatch, a connecting piece 8 is attached to the band piece 6a at one end of the band body 6, and a connecting body 10 is attached to this connecting piece 8. Therefore, by simply sliding the operating lever 14 of this connecting body 10, the watch band 2 can be simply and easily attached to the band attachment part 5 of the wristwatch case 1, and the watch band 2 can be simply and easily removed from the band attachment part 5 of the wristwatch case 1 and replaced.

なお、上述した実施形態では、操作レバー１４の先端に押付部１６を設けた場合について述べたが、この発明は、これに限らず、例えば図９に示された変形例のように、押付部２０をスライド部材１３の大径部１３ａに操作レバー１４と位置をずらして別に設けた構造であっても良い。この場合、押付部２０は、金属で形成されていても良いが、滑り性を有するポリアセタールなどの合成樹脂で形成されていることが望ましい。 In the above embodiment, the pressing portion 16 is provided at the tip of the operating lever 14, but the present invention is not limited to this. For example, as in the modified example shown in FIG. 9, the pressing portion 20 may be provided separately from the operating lever 14 on the large diameter portion 13a of the slide member 13. In this case, the pressing portion 20 may be made of metal, but is preferably made of a synthetic resin such as polyacetal that has slipperiness.

また、上述した実施形態および変形例では、押付部１６がステンレスなどの金属またはポリアセタールなどの合成樹脂で形成されている場合について述べたが、この発明は、これに限らず、弾力性を有する弾性部材で形成されていても良い。 In addition, in the above-described embodiment and modified example, the pressing portion 16 is described as being formed from a metal such as stainless steel or a synthetic resin such as polyacetal, but the present invention is not limited to this, and the pressing portion 16 may be formed from an elastic material having elasticity.

また、上述した実施形態では、押付部１６をロックするロック部１７がカム部１５ｂの湾曲したカム面に設けられた凹部である場合について述べたが、この発明は、これに限らず、押付部１６がカム部１５ｂのカム面に押し付けられる際に、押付部１６が乗り越える凸部であっても良い。 In addition, in the above embodiment, the locking portion 17 that locks the pressing portion 16 is a recess provided on the curved cam surface of the cam portion 15b, but the present invention is not limited to this, and the locking portion 17 may be a convex portion that the pressing portion 16 overcomes when the pressing portion 16 is pressed against the cam surface of the cam portion 15b.

また、上述した実施形態および変形例では、押付部１６をスライド部材１３の大径部１３ａに位置する箇所に設けた場合について述べたが、この発明は、これに限らず、例えば押付部１６を筒状部材であるパイプ１１の外周面に設けても良い。この場合には、連結駒８の駒本体８ａに設けられる切欠き部１５をパイプ１１の外周面に対応する箇所に延長させて設ければよい。 In addition, in the above-mentioned embodiment and modified example, the pressing portion 16 is provided at a location located on the large diameter portion 13a of the slide member 13, but the present invention is not limited to this. For example, the pressing portion 16 may be provided on the outer peripheral surface of the pipe 11, which is a cylindrical member. In this case, the notch portion 15 provided on the link body 8a of the connecting link 8 may be extended to a location corresponding to the outer peripheral surface of the pipe 11.

また、上述した実施形態および変形例では、押付部１６を突起状に形成した場合について述べたが、この発明は、これに限らず、例えば押付部として、筒状部材であるパイプ１１の断面形状を非円形状に形成しても良い。この場合には、スライド部材１３の大径部１３ａをパイプ１１の断面形状と同じ断面形状に形成すれば良い。 In addition, in the above-mentioned embodiment and modified example, the pressing portion 16 is formed in a protrusion shape, but the present invention is not limited to this. For example, the cross-sectional shape of the pipe 11, which is a cylindrical member, may be formed in a non-circular shape as the pressing portion. In this case, the large diameter portion 13a of the sliding member 13 may be formed in the same cross-sectional shape as the cross-sectional shape of the pipe 11.

また、上述した実施形態では、時計バンド２の連結駒８に連結体１０を取り付けた場合について述べたが、この発明は、これに限らず、例えば腕時計ケース１のバンド取付部に連結体１０を取り付け、この連結体１０によって時計バンド２の連結駒を腕時計ケース１のバンド取付部に取り付けるようにしても良い。 In the above embodiment, the connecting body 10 is attached to the connecting piece 8 of the watch band 2, but the present invention is not limited to this. For example, the connecting body 10 may be attached to the band attachment portion of the watch case 1, and the connecting piece of the watch band 2 may be attached to the band attachment portion of the watch case 1 using this connecting body 10.

この場合には、腕時計ケース１のバンド取付部を凸形状に形成し、時計バンド２の連結駒にバンド取付部が配置される連結凹部を設け、この連結駒の連結凹部の両側に連結体１０のスライド部材１３の小径部１３ｂが挿入する取付孔を設けた構造にすれば良い。 In this case, the band attachment portion of the watch case 1 is formed in a convex shape, a connecting recess is provided in the connecting piece of the watch band 2 in which the band attachment portion is placed, and mounting holes are provided on both sides of the connecting recess of the connecting piece into which the small diameter portion 13b of the sliding member 13 of the connecting body 10 is inserted.

さらに、上述した実施形態およびその各変形例では、腕時計に適用した場合について述べたが、この発明は必ずしも腕時計である必要はなく、例えば洋服、鞄、バッグなどのバンドにも適用することができる。 Furthermore, while the above-mentioned embodiment and its variations have been described as being applied to a wristwatch, the invention does not necessarily have to be applied to a wristwatch, but can also be applied to bands for clothing, bags, purses, etc., for example.

以上、この発明の一実施形態について説明したが、この発明は、これに限られるものではなく、特許請求の範囲に記載された発明とその均等の範囲を含むものである。
以下に、本願の特許請求の範囲に記載された発明を付記する。 Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and includes the inventions described in the claims and their equivalents.
