Description

本発明は、時計用バンド及びこのバンドが胴に着脱可能に取付けられた腕時計に関する。   The present invention relates to a watch band and a wristwatch having the band detachably attached to the case.

腕時計の胴にバンドを取付けるには一般的にばね棒を用いる構成が多用されている（例えば、特許文献１参照。）。   In general, a structure using a spring bar is often used to attach a band to a wristwatch body (see, for example, Patent Document 1).

この特許文献１の技術では、ハンドのエンドピースにその幅方向に延びる貫通孔を設けるとともに、このエンドピースを受入れるかん股を相互間に形成した胴のかん足に夫々取付け穴を設けている。そして、内蔵ばねで突出方向に付勢された段付きピンを軸方向両側に夫々有してなるばね棒を、エンドピースの貫通孔に通すとともに、このばね棒の段付きピンをかん足の取付け穴に夫々挿入させることによって、バンドを胴に連結している。この連結及びその解除、つまり、胴にバンドを着脱するに際には、ピンセットなどの専用工具を用いて段付きピンを内蔵ばねに抗して押し込む作業を要する。   In the technique of this Patent Document 1, a through hole extending in the width direction is provided in the end piece of the hand, and attachment holes are provided in the forefoot of the trunk formed with a crotch for receiving the end piece. Then, the spring rods having stepped pins urged in the protruding direction by the built-in springs are passed through the through holes of the end pieces, and the stepped pins of the spring rods are attached to the hooks. The band is connected to the trunk by inserting each into the hole. When this connection and its release, that is, when the band is attached to and detached from the body, it is necessary to push the stepped pin against the built-in spring using a dedicated tool such as tweezers.

又、腕時計の胴に対してねじを用いてバンドを取付ける技術も知られている（例えば、特許文献２参照。）。   In addition, a technique for attaching a band to a wristwatch body using a screw is also known (see, for example, Patent Document 2).

この特許文献２は、胴に突設したフランジ部に貫通孔を形成し、フランジ部に被さるバンドのエンドピース裏面に前記貫通孔に挿入されるねじパイプを固定し、このねじパイプにフランジ部の裏面からねじを螺合して、胴にバンドを着脱可能にねじ止めする技術を示している。更に、特許文献２は、胴にバンド挿入溝を形成するとともにフランジ部を突設して、フランジ部にねじ穴を形成し、このフランジ部に被さるバンドのエンドピースをフランジ部の先端部裏面に引っ掛けるとともにバンド挿入溝に挿入させた状態で、ねじ穴に螺合されるねじでエンドピースを押し上げて、胴にバンドを着脱可能にねじ止めする技術を示している。
特開昭６１−１５４６０４号公報（第１頁左欄第１８行〜第２頁左上欄第１６行、図２−図４） 特開昭６２−９４１０３号公報（第２頁左上欄第２行〜同頁右上欄第１２行、第２頁右下欄第８行〜第３頁右上欄第８行、図１−図７） In this patent document 2, a through-hole is formed in a flange portion protruding from a body, and a screw pipe inserted into the through-hole is fixed to the back surface of an end piece of a band covering the flange portion. A technique is shown in which a screw is screwed from the back surface and a band is detachably screwed to the body. Further, in Patent Document 2, a band insertion groove is formed in the body and a flange portion is projected, a screw hole is formed in the flange portion, and an end piece of the band covering the flange portion is formed on the back surface of the front end portion of the flange portion. A technique is shown in which the end piece is pushed up with a screw that is screwed into a screw hole while being hooked and inserted into the band insertion groove, and the band is detachably screwed to the body.
JP-A-61-154604 (first page, left column, line 18 to page 2, upper left column, line 16, FIG. 2 to FIG. 4) JP-A-62-94103 (2nd page, upper left column, 2nd line to upper right column, 12th line, 2nd page, lower right column, 8th line to 3rd page, upper right column, 8th line, FIGS. 1 to 7) )

胴へのバンドの連結にばね棒を用いる特許文献１の技術では、胴に対するバンドの着脱に専用工具を用いなければならないので、不便である。しかも、ばね棒の段付きピンは突出方向に常に付勢されてので、バンドを着脱する際に、ばね棒の段付きピンの先端が胴のかん足を擦ることがあると、胴が傷付けられる恐れがある。   The technique of Patent Document 1 that uses a spring bar to connect the band to the trunk is inconvenient because a dedicated tool must be used to attach and detach the band to and from the trunk. In addition, since the stepped pin of the spring bar is always urged in the protruding direction, if the tip of the stepped pin of the spring bar rubs the leg of the barrel when attaching or detaching the band, the barrel is damaged. There is a fear.

胴へのバンドの連結にねじを用いる特許文献２の技術では、連結に伴い胴が傷付けられる恐れはないが、連結に使用するねじは一般的なねじに比較して遥かに小さいので、それに合った専用工具（この場合小型ねじ回し）を用いなければならないので、胴に対するバンドの着脱作業が不便であるという点では特許文献１の技術と同じである。   In the technique of Patent Document 2 in which a screw is used for connecting a band to a drum, there is no risk of the drum being damaged along with the connection, but the screw used for the connection is much smaller than a general screw, so it is suitable for it. Since a dedicated tool (in this case, a small screwdriver) must be used, the technique of Patent Document 1 is the same in that it is inconvenient to attach and detach the band to and from the trunk.

しかも、ばね棒やねじ等の連結部品は、バンド交換をする際に胴又はバンドから外されるので、紛失するおそれがある。   In addition, connecting parts such as spring bars and screws are removed from the trunk or band when the band is exchanged, and thus may be lost.

以上のように従来は、胴に対するバンドの着脱に専用工具が必要であり、その作業も容易ではないとともに、連結部品を紛失する恐れがある。このため、従来の技術は、腕時計の意匠に変化を与えて使用するために、例えば使用者が任意にバンドを交換しようとする場合には不適当である。   As described above, conventionally, a dedicated tool is required for attaching and detaching the band to and from the trunk, and the work is not easy, and there is a risk of losing the connecting parts. For this reason, the conventional technique is not suitable for a case where the user intends to change the band arbitrarily, for example, in order to change the design of the wristwatch.

本発明の目的は、専用工具を用いることなく胴に対して容易に着脱できる時計用バンド及び腕時計を提供することにある。   An object of the present invention is to provide a watch band and a wristwatch that can be easily attached to and detached from the case without using a dedicated tool.

前記課題を解決するために、本発明は、胴にバンドが着脱可能に連結された腕時計において、前記バンドのエンドピースと胴の内の一方に設けられた凸部と、この凸部を受入れる収容凹部及びこの収容凹部に連通する連結孔を有して前記一方に対する他方に設けられた筒部と、押込み操作面及びこの操作面から折れ曲がるように連なる一対の係合面が形成された係合ヘッドを有して、前記凸部に移動可能でかつ外れ止めされて取付けられるとともに、この移動により前記連結孔に前記係合ヘッドが挿脱される連結部品と、前記押込み操作面が前記凸部の一面から突出するように前記連結部品を付勢する付勢部材と、を具備している。   In order to solve the above-described problems, the present invention provides a wristwatch in which a band is detachably connected to a trunk, and a projection provided on one of the end piece of the band and the trunk, and a housing for receiving the projection. An engagement head having a concave portion and a connecting hole communicating with the receiving concave portion and provided with a cylindrical portion provided on the other side of the one side, a push operation surface, and a pair of engagement surfaces that are bent from the operation surface A connecting part that is movable and attached to the convex part and is attached to the convex part by the movement, and the push-in operation surface of the convex part is And a biasing member that biases the connecting component so as to protrude from one surface.

この発明の腕時計では、筒部の収容凹部と凸部とを嵌合させることにより、付勢部材の付勢力に抗して凸部内に没するように連結部品が一旦移動された後に、この部材の係合ヘッドが連結孔に適正に対向するに伴い付勢部材により連結部品が押し動かされる。それにより、連結孔内に係合ヘッドが入り込んで、その係合面が連結孔の縁に引っ掛かって、胴とバンドとを連結できる。この連結状態では、係合ヘッドの押込み操作面が外部から押込み可能に配置されている。このため、押込み操作面を指先などで押して連結部品を付勢部材の付勢力に抗して押込みながら凸部と筒部とを引き離すことにより、胴からバンドを外すことができる。   In the wristwatch of the present invention, after the connecting part is once moved so as to be immersed in the convex part against the urging force of the urging member by fitting the accommodating concave part and the convex part of the cylindrical part, this member As the engagement head properly faces the connection hole, the connection component is pushed by the biasing member. As a result, the engagement head enters the connection hole, and the engagement surface is caught by the edge of the connection hole, so that the body and the band can be connected. In this connected state, the pushing operation surface of the engaging head is arranged so as to be pushed from the outside. For this reason, the band can be removed from the trunk by pushing the pushing operation surface with a fingertip or the like and pulling the convex part and the cylindrical part while pushing the connecting part against the urging force of the urging member.

本発明の腕時計の好ましい形態では、一対の前記係合面の内の少なくとも前記凸部の先端側に位置する係合面と前記押込み操作面とがなす前記係合ヘッドの角部に面取りされた斜状面を設けるとともに、この斜状面に対応させて前記筒部の先端縁に前記収容凹部に臨んで面取りされた斜状面を設けている。   In a preferred embodiment of the wristwatch according to the present invention, the corner of the engagement head formed by the engagement surface located at least on the distal end side of the convex portion and the push operation surface of the pair of engagement surfaces is chamfered. A sloped surface is provided, and a sloped surface chamfered facing the housing recess is provided at the leading edge of the cylindrical portion so as to correspond to the sloped surface.

この発明の形態では、胴にバンドを連結する際、係合ヘッドの角部の斜状面と筒部の斜状面とが当たるに伴い、係合ヘッドと筒部の先端縁とが引っ掛かることを防止しつつ連結部品が付勢部材に抗して押込まれるので、凸部と筒部とを円滑に嵌合させて胴にバンドを連結できる。   In the embodiment of the present invention, when the band is connected to the body, the engaging head and the leading edge of the cylindrical portion are caught as the diagonal surface of the corner of the engaging head hits the diagonal surface of the cylindrical portion. Since the connecting component is pushed against the biasing member while preventing the band, the convex portion and the cylindrical portion can be smoothly fitted to connect the band to the trunk.

又、本発明の好ましい形態では、前記凸部と筒部とが嵌合された連結状態で、前記係合ヘッドを前記連結孔が開けられた前記筒部の外面から陥没させている。   In a preferred embodiment of the present invention, the engaging head is depressed from the outer surface of the cylindrical portion in which the connecting hole is opened in a connected state in which the convex portion and the cylindrical portion are fitted.

この発明の形態では、連結孔に引っ掛かっている連結部材の係合ヘッドが筒部の外面から陥没しているので、不用意に係合ヘッドが押込まれる恐れがない。   In the embodiment of the present invention, since the engaging head of the connecting member hooked in the connecting hole is depressed from the outer surface of the cylindrical portion, there is no possibility that the engaging head is inadvertently pushed.

又、本発明の好ましい形態では、前記連結孔を前記筒部の裏壁に開けている。   Moreover, in the preferable form of this invention, the said connection hole is opened in the back wall of the said cylinder part.

この発明の形態では、腕時計の使用時に、使用者の腕によって連結孔が閉じられるので、腕時計の表側から不用意に係合ヘッドが押込まれる恐れがない。   In the embodiment of the present invention, since the connecting hole is closed by the user's arm when the wristwatch is used, there is no possibility that the engaging head is inadvertently pushed from the front side of the wristwatch.

又、本発明の好ましい形態では、前記押込み操作面が前記凸部の一面から突出されたときに前記連結部品に設けた外れ止めが当たる位置決め面を前記凸部に設けている。   In a preferred embodiment of the present invention, the convex portion is provided with a positioning surface on which the stopper provided on the connecting part hits when the pushing operation surface protrudes from one surface of the convex portion.

この発明の形態では、付勢部材の付勢力で連結部品が押されてその係合ヘッドが連結孔に係合する時などに、位置決め面に連結部品の外れ止めが当接する音が発生するので、胴に対するバンドの取付け完了を使用者等に知覚させることができる。   In the embodiment of the present invention, when the connecting component is pushed by the biasing force of the biasing member and the engaging head engages with the connecting hole, a noise is generated that the stopper of the connecting component comes into contact with the positioning surface. The user or the like can perceive the completion of the attachment of the band to the trunk.

又、前記課題を解決するために、本発明は、押込み操作面及びこの操作面から折れ曲がるように連なる一対の係合面が形成された係合ヘッドを有した連結部品を、胴に設けられた凸部に移動可能でかつ外れ止めして取付け、この連結部品を前記押込み操作面が前記凸部の一面から突出するように付勢部材で付勢した腕時計に備えられ、前記凸部に着脱可能に連結される時計用バンドであって、エンドピースを備え、このエンドピースに前記凸部を受入れる収容凹部を設けるとともに、前記エンドピースに前記係合ヘッドが挿脱される連結孔を前記収容凹部に連通して設けている。   In order to solve the above-mentioned problems, the present invention is provided with a connecting part having a pushing operation surface and an engagement head formed with a pair of engagement surfaces connected to bend from the operation surface. Mounted on a wristwatch that can move to the convex part and prevent it from coming off, and this connecting part is urged by a biasing member so that the push-in operation surface protrudes from one surface of the convex part. A watch band connected to the end piece, the end piece being provided with a receiving recess for receiving the convex portion, and a connecting hole into which the engagement head is inserted and removed from the end piece. Are provided in communication with each other.

この発明の時計用バンドでは、そのエンドキャップの筒部の収容凹部を胴の凸部に嵌合させることにより、付勢部材の付勢力に抗して凸部内に没するように連結部品が一旦移動された後に、この部材の係合ヘッドが連結孔に適正に対向するに伴い付勢部材により連結部品が押し動かされる。それにより、筒部の連結孔内に係合ヘッドが入り込んで、その係合面が連結孔の縁に引っ掛かって、バンドを胴に連結できる。この連結状態では、係合ヘッドの押込み操作面が外部から押込み可能に配置されている。このため、押込み操作面を指先などで押して連結部品を付勢部材の付勢力に抗して押込みながら凸部と筒部とを引き離すことにより、胴からバンドを外すことができる。   In the timepiece band of the present invention, the connecting part is temporarily suspended so as to be immersed in the convex portion against the urging force of the urging member by fitting the accommodating concave portion of the cylindrical portion of the end cap into the convex portion of the case. After the movement, the connecting component is pushed by the biasing member as the engaging head of this member properly faces the connecting hole. As a result, the engagement head enters the connection hole of the cylindrical portion, and the engagement surface is caught by the edge of the connection hole, so that the band can be connected to the trunk. In this connected state, the pushing operation surface of the engagement head is arranged to be pushed from the outside. For this reason, the band can be removed from the trunk by pushing the pushing operation surface with a fingertip or the like and pulling the convex part and the cylindrical part while pushing the connecting part against the urging force of the urging member.

又、前記課題を解決するために、本発明は、収容凹部及びこの収容凹部に連通する連結孔を有した筒部を胴に設けた腕時計に備えられ、前記筒部に着脱可能に連結される時計用バンドであって、前記収容凹部に受入れられる凸部が設けられたエンドピースと、押込み操作面及びこの操作面から折れ曲がるように連なる一対の係合面が形成された係合ヘッドを有して、前記凸部に移動可能でかつ外れ止めされて取付けられるとともに、この移動により前記連結孔に前記係合ヘッドが挿脱される連結部品と、前記押込み操作面が前記凸部の一面から突出するように前記連結部品を付勢する付勢部材と、を具備している。   Further, in order to solve the above-mentioned problems, the present invention is provided in a wristwatch having a cylinder portion having a housing recess and a connecting hole communicating with the housing recess, and is detachably connected to the tube portion.

It is preferable that the pushing operation surface 14a is formed by a plane orthogonal to the longitudinal direction of the shaft portion 13 and has an area that can be pushed by a fingernail of a user's finger. In this embodiment, the pushing operation surface 14a has a rectangular shape extending in the 3 o'clock to 9 o'clock direction of the dial, but may be a rhombus or an ellipse extending in the same direction.

一対の係合面１４ｂは軸部１３と平行であって、これらは押込み操作面１４ａから折れ曲がるように連なって形成されている。これらの係合面１４ｂと押込み操作面１４ａとがなす係合ヘッド１４の角部には、面取りされた斜状面１４ｃが夫々設けられている。したがって、押込み操作面１４ａと一対の係合面１４ｂとは斜状面１４ｃを介して連なっている。なお、斜状面１４ｃは凸部１１の先端側に位置する係合面１４ｂと押込み操作面１４ａとにわたってだけ設けてもよい。斜状面１４ｃは斜面又は円弧面で形成される。   The pair of engaging surfaces 14b are parallel to the shaft portion 13, and are formed so as to be bent from the pushing operation surface 14a. A chamfered oblique surface 14c is provided at each corner of the engagement head 14 formed by the engagement surface 14b and the pushing operation surface 14a. Therefore, the pushing operation surface 14a and the pair of engaging surfaces 14b are connected via the inclined surface 14c. The oblique surface 14c may be provided only over the engaging surface 14b located on the tip side of the convex portion 11 and the pushing operation surface 14a. The inclined surface 14c is formed as a slope or an arc surface.

係合ヘッド１４の全長、つまり、押込み操作面１４ａから軸部１３の先端面までの寸法は、凸部１１の互いに平行な二面例えば表裏面間の距離（言い換えれば凸部１１の厚みより僅かに短い。この係合ヘッド１４を有した連結部品１２は、軸部１３を通孔１１ｃに貫通させるとともに、係合ヘッド１４を第１の溝１１ａに収容して凸部１１に組込まれて、通孔１１ｃ及び第１の溝１１ａの側面をガイドとして凸部１１の厚み方向に移動可能に設けられている。   The total length of the engagement head 14, that is, the dimension from the pushing operation surface 14a to the tip surface of the shaft portion 13, is a distance between two parallel surfaces of the convex portion 11 such as the front and back surfaces (in other words, slightly smaller than the thickness of the convex portion 11). The connecting component 12 having the engagement head 14 is inserted into the projection 11 by accommodating the engagement head 14 in the first groove 11a while penetrating the shaft portion 13 through the through hole 11c. The side surface of the through-hole 11c and the 1st groove | channel 11a is provided so that a movement in the thickness direction of the convex part 11 is made into a guide.

第２の溝１１ｂ内に位置した軸部１３の先端部には外れ止め１５が取付けられている。外れ止め１５は、軸部１５に連結された止め輪によって形成されている。しかし、これに代えて、軸より大径な頭部を有するねじを軸部１３の端面にねじ込んで、このねじを外れ止めとすることもできる。この外れ止め１５は位置決め面１１ｄに接離可能である。外れ止め１５及び凸部１１は、位置決め面１１ｄへの当たり音を明確に得るために金属製とすることが好ましい。   A stopper 15 is attached to the tip of the shaft 13 located in the second groove 11b. The stopper 15 is formed by a retaining ring connected to the shaft portion 15. However, instead of this, a screw having a head having a diameter larger than that of the shaft may be screwed into the end surface of the shaft portion 13 to prevent the screw from coming off. This detachment stop 15 can be contacted and separated from the positioning surface 11d. The stopper 15 and the protrusion 11 are preferably made of metal in order to clearly obtain a hitting sound on the positioning surface 11d.

付勢部材１６には例えばコイルばねが用いられている。この付勢部材１６にはコイルばねに代えて板ばねを用いることができる。この場合は、連結部品１２の移動ストロークをより大きく確保できる点で好ましい。付勢部材１６は、軸部１３に巻き付くようにして係合ヘッド１４の裏面と第１の溝１１ａの奥面とに両端を当てて圧縮状態に組込まれている。連結部品１２は、その係合ヘッド１４の押込み操作面１４ａ側部分が凸部１１の一面である裏面から突出するようにこの付勢部材１６によって付勢され、それにより、係合ヘッド１４を凸部１１の表面方向に押込み可能している。   For example, a coil spring is used for the urging member 16. A plate spring can be used as the urging member 16 in place of the coil spring. In this case, it is preferable at the point which can ensure the movement stroke of the connection component 12 more largely. The urging member 16 is assembled in a compressed state such that the urging member 16 is wound around the shaft portion 13 with both ends being in contact with the back surface of the engagement head 14 and the back surface of the first groove 11a. The connecting component 12 is urged by the urging member 16 so that the portion of the engagement head 14 on the side of the pressing operation surface 14a protrudes from the back surface, which is one surface of the convex portion 11, thereby causing the engagement head 14 to be convex. Pushing in the surface direction of the part 11 is possible.

この状態では、図２及び図４に示すように外れ止め１５が位置決め面１１ｄに当たって連結部品１２が外れ止めされるとともに、係合面１４ｂの押込み操作面１４ａ側の部位が第２の溝１１ｂから突出されるようになっている。更に、図２及び図４に示す状態で、軸部１３の先端面と凸部１１の表面との間の距離Ｈ１と、第１の溝１１ａの奥面とこれに対向する係合ヘッド１４の裏側端面との間の距離Ｈ２との関係は、Ｈ２≦Ｈ１に設定されている。   In this state, as shown in FIG. 2 and FIG. 4, the stopper 15 hits the positioning surface 11d and the connecting component 12 is prevented from coming off, and the portion of the engaging surface 14b on the pushing operation surface 14a side is separated from the second groove 11b. It is designed to protrude. Further, in the state shown in FIGS. 2 and 4, the distance H1 between the tip surface of the shaft portion 13 and the surface of the convex portion 11, the back surface of the first groove 11a, and the engagement head 14 facing this. The relationship with the distance H2 between the rear side end face is set to H2 ≦ H1.

一方、図２〜図４に示すようにエンドピース６には筒部１７が設けられていて、この筒部１７に収容凹部１８と連結孔１９が設けられている。収容凹部１８は、エンドピース６の先端面に開放して胴５の凸部１１を受入れる大きさに形成されている。連結孔１９は、収容凹部１８を区画する筒部１７の例えば裏壁１７ａに開放して設けられていて、収容凹部１８と連通している。この連結孔１９は、例えば長方形状をなして係合ヘッド１４を受入れる大きさに形成されている。   On the other hand, as shown in FIGS. 2 to 4, the end piece 6 is provided with a cylindrical portion 17, and the cylindrical concave portion 18 is provided with an accommodation recess 18 and a connecting hole 19. The housing recess 18 is formed in a size that opens to the distal end surface of the end piece 6 and receives the projection 11 of the barrel 5. The connecting hole 19 is provided open to, for example, the back wall 17 a of the cylindrical portion 17 that defines the housing recess 18, and communicates with the housing recess 18. The connecting hole 19 has a rectangular shape, for example, and is sized to receive the engaging head 14.

図４に示すように筒部１７の裏壁１７ａの厚みＨ３と、凸部１１からの係合ヘッド１４の突出寸法Ｈ４との関係は、Ｈ３≧Ｈ４に設定されている。本実施形態の場合には、Ｈ３＞Ｈ４の関係に設定されている。それにより、図２に示すように凸部１１と筒部１７とが嵌合された連結状態で、連結孔１９が開けられた筒部１７の外面に対して係合ヘッド１４が陥没されるようになっている。連結孔１９が開けられた裏壁１７ａの先端縁には、収容凹部１８に臨んで面取りされた斜状面１７ｂが設けられている。この斜状面１７ｂは斜面又は円弧面で形成される。   As shown in FIG. 4, the relationship between the thickness H3 of the back wall 17a of the cylindrical portion 17 and the protrusion dimension H4 of the engagement head 14 from the convex portion 11 is set to H3 ≧ H4. In the present embodiment, the relationship of H3> H4 is set. Thereby, as shown in FIG. 2, the engagement head 14 is depressed with respect to the outer surface of the cylinder part 17 in which the connection hole 19 is opened in a connected state in which the convex part 11 and the cylinder part 17 are fitted. It has become. At the front edge of the back wall 17a in which the connection hole 19 is opened, a beveled surface 17b chamfered facing the housing recess 18 is provided. The oblique surface 17b is formed as an inclined surface or an arc surface.

時計外装組立２の胴５にバンド３を連結するには、図４に示すようにバンド３の筒部１７の開放面を、胴５の凸部１１に対向させて、筒部１７を凸部１１に嵌合させればよい。   In order to connect the band 3 to the case 5 of the watch exterior assembly 2, as shown in FIG. 4, the cylindrical part 17 is formed as a convex part with the open surface of the cylindrical part 17 of the band 3 facing the convex part 11 of the case 5. 11 may be fitted.

それにより、まず、凸部１１の先端側に位置した方の係合ヘッド１４の斜状面１４ｃに筒部１７の斜状面１７ｂが接する。このため、連結部品１２の係合ヘッド１４と筒部１７の先端面とが引っ掛かることがないとともに、連結部品１２が付勢部材１６の付勢力に抗して凸部１１の上面方向に円滑に押込まれるので、凸部１１に対する筒部１７の嵌合を深くすることができる。   Thereby, first, the oblique surface 17b of the cylindrical portion 17 is in contact with the oblique surface 14c of the engagement head 14 located on the tip side of the convex portion 11. For this reason, the engaging head 14 of the connecting part 12 and the tip end surface of the cylindrical part 17 are not caught, and the connecting part 12 smoothly resists the biasing force of the biasing member 16 in the upper surface direction of the convex part 11. Since it is pushed in, the fitting of the cylinder part 17 with respect to the convex part 11 can be deepened.

この嵌合の進行により、図３に示す状態を経て、相対的に凸部１１が筒部１７の奥に到達して、連結孔１９に係合ヘッド１４が正対するようになるので、この時点において付勢部材１６の付勢力で連結部品１２が移動される。これにより、凸部１１の裏面から突出された係合ヘッド１４が、図２に示すように連結孔１９に嵌合されるとともに、この連結孔１９の縁に係合ヘッド１４の係合面１４ｂが引っ掛かって、胴５にバンド３が取付けられる。なお、以上のバンド３の取付けにおいて、係合ヘッド１４を手指で押込みながら、凸部１１にバンド３の筒部１７を嵌合させてもよい。   As the fitting progresses, the convex portion 11 relatively reaches the back of the cylindrical portion 17 through the state shown in FIG. 3, and the engaging head 14 faces the connecting hole 19 at this time. The connecting component 12 is moved by the urging force of the urging member 16. Thereby, the engaging head 14 protruding from the back surface of the convex portion 11 is fitted into the connecting hole 19 as shown in FIG. 2, and the engaging surface 14 b of the engaging head 14 is formed at the edge of the connecting hole 19. The band 3 is attached to the trunk 5. In the above-described attachment of the band 3, the cylindrical portion 17 of the band 3 may be fitted to the convex portion 11 while pushing the engagement head 14 with fingers.

こうしたバンド３の取付け作業によれば、バンド３のエンドピース６に設けた筒部１７を胴５に設けた凸部１１に嵌合させるという簡単な作業で、格別に専用工具を要することなく、バンド３を胴５に連結できる。   According to such a band 3 mounting operation, a simple operation of fitting the cylindrical portion 17 provided on the end piece 6 of the band 3 to the convex portion 11 provided on the barrel 5, without requiring a special tool, The band 3 can be connected to the trunk 5.

しかも、この連結において、既述のように付勢部材１６の付勢力で係合ヘッド１４が連結孔１９に係合する時に、第２の溝１１ｂの位置決め面１１ｄに連結部品１２に固定した外れ止め１５が当接するので、それに伴う発音により、胴５に対するバンド３の取付け完了を使用者等に知覚させることができる。   Moreover, in this connection, when the engagement head 14 is engaged with the connection hole 19 by the urging force of the urging member 16, as described above, the disengagement fixed to the connection component 12 on the positioning surface 11d of the second groove 11b. Since the stop 15 comes into contact, the user or the like can perceive the completion of the attachment of the band 3 to the body 5 by the sound produced by the stop 15.

筒部１７の裏壁１７ａに開けられた連結孔１９は、腕時計１の使用時に、使用者の腕によって閉じられるので、腕時計１の表側から不用意に連結孔１９に引っ掛かっている係合ヘッド１４に物品が当たって、この係合ヘッド１４が押込まれる恐れがない。しかも、バンド３が胴５に連結された状態では、図２に示すように連結孔１９が開けられた筒部１７の裏壁１７ａの外面から係合ヘッド１４が陥没している。このため、腕時計１の使用時に不用意に係合ヘッド１４が押込まれる恐れがない。更に、本実施形態では、筒部１７の表壁１７ｃで連結部品１２を覆い隠したので、外観上好ましい。   Since the connecting hole 19 opened in the back wall 17a of the cylindrical portion 17 is closed by the user's arm when the wristwatch 1 is used, the engagement head 14 is inadvertently caught in the connecting hole 19 from the front side of the wristwatch 1. There is no possibility that the engaging head 14 will be pushed by hitting the article. In addition, in the state where the band 3 is connected to the body 5, the engagement head 14 is depressed from the outer surface of the back wall 17 a of the cylindrical portion 17 in which the connection hole 19 is opened as shown in FIG. 2. For this reason, there is no possibility that the engaging head 14 is inadvertently pushed when the wristwatch 1 is used. Furthermore, in this embodiment, since the connection component 12 was covered and covered with the front wall 17c of the cylinder part 17, it is preferable on the external appearance.

バンド３の交換などにおいて、胴５からバンド３を取外すには、まず、連結孔１９に係合ヘッド１４の押込み操作面１４ａを指先などで押すことによって、連結部品１２を付勢部材１６の付勢力に抗して押込みながら凸部１１と筒部７とを引き離せばよい。これにより、図２に示す状態から図３に示す状態を得て図４に示すように胴５からバンド３を外すことができる。   In order to remove the band 3 from the body 5 in exchange of the band 3 or the like, first, the pushing operation surface 14a of the engaging head 14 is pushed into the connecting hole 19 with a fingertip or the like to attach the connecting component 12 to the biasing member 16. What is necessary is just to pull apart the convex part 11 and the cylinder part 7, pushing against a force. Thereby, the state shown in FIG. 3 can be obtained from the state shown in FIG. 2, and the band 3 can be removed from the trunk 5 as shown in FIG.

こうしたバンド３の取外し作業によれば、連結孔１９内の係合ヘッド１４を押込みながら凸部１１と筒部１７とを引き離すという簡単な作業で、格別に専用工具を要することなく、胴５からバンド３を外すことができる。   According to such a removal work of the band 3, it is a simple work of pulling away the convex portion 11 and the cylindrical portion 17 while pushing the engagement head 14 in the connecting hole 19. Band 3 can be removed.

従って、前記構成の腕時計１は、その組み立て作業性が良いとともに、使用者においても容易にバンド３を胴５に着脱できる。これにより、前記筒部１７を有したエンドピース６を備えた意匠が異なる複数のバンド３を使用者が用意して置く場合には、既述の手順により容易に所望のバンド３に適宜交換して、腕時計１に意匠の変化を与えて使用することが可能となる。   Therefore, the wristwatch 1 having the above-described structure has good assembling workability, and the user can easily attach and detach the band 3 to and from the trunk 5. Thereby, when a user prepares and arranges a plurality of bands 3 having different designs including the end piece 6 having the cylindrical portion 17, the band 3 can be easily replaced with a desired band 3 according to the procedure described above. Thus, the wristwatch 1 can be used with a design change.

又、バンド３の連結状態（図２参照）、及びバンド３が胴５から分離された状態（図４参照）のいずれにおいても、連結部品１２は付勢部材１６で付勢されていて、外れ止め１５が位置決め面１１ｄに引っ掛かっている。このため、胴５にバンド３が連結された状態でも、胴５からバンド３が外された状態でも、付勢部材１６の付勢力によって連結部品１２が凸部１１から離脱して紛失する恐れがない。   Further, in both the connected state of the band 3 (see FIG. 2) and the state in which the band 3 is separated from the trunk 5 (see FIG. 4), the connecting component 12 is urged by the urging member 16 and is detached. The stopper 15 is caught on the positioning surface 11d. For this reason, even when the band 3 is connected to the body 5 or when the band 3 is removed from the body 5, there is a possibility that the connecting component 12 may be detached from the convex portion 11 and lost due to the urging force of the urging member 16. Absent.
