以下に、本発明の実施例を図面に基づいて説明する。まず、本発明が実施されている本例のからくり時計について説明すると、このからくり時計１は、時計文字板２が回転する形式のものである。時計文字板２は、中央部を切り欠き形成したリング状板２ａで構成され、文字板２の背面側には、リング歯車２ｂ設ける。尚、図２において、１ａはムーブメントである。   Embodiments of the present invention will be described below with reference to the drawings. First, a description will be given of a timepiece timepiece according to the present embodiment in which the present invention is implemented. The timepiece timepiece 1 is of a type in which a timepiece dial 2 rotates. The timepiece dial plate 2 is constituted by a ring-shaped plate 2a formed by cutting out a central portion, and a ring gear 2b is provided on the back side of the dial plate 2. In FIG. 2, reference numeral 1a denotes a movement.

時計支持板３には、時計文字板２を回転駆動させるモータユニットＭを備える。前記モータユニットＭは、モータの回転軸に駆動連係する輪列４を備える。本例では、モータユニットＭは時計の下部に設けられており、輪列４は、時計の正面視において左側に設けられている。   The timepiece support plate 3 includes a motor unit M that rotates the timepiece dial plate 2. The motor unit M includes a train wheel 4 that is drivingly linked to the rotation shaft of the motor. In this example, the motor unit M is provided at the lower part of the timepiece, and the train wheel 4 is provided on the left side in a front view of the timepiece.

輪列４には、駆動歯車４ａが設けられており、この駆動歯車４ａは、文字板２のリング歯車２ｂと噛み合う。   The gear train 4 is provided with a drive gear 4 a, and this drive gear 4 a meshes with the ring gear 2 b of the dial 2.

前記リング歯車２ｂと、輪列４の駆動歯車４ａとが噛み合う箇所の時計支持板３には、リング歯車２ｂを外周側から支持するプーリー５を設けている。このように、プーリー５を、輪列４の駆動歯車４ａと噛み合う箇所に設けているので、当該箇所の噛み合い状態が保持され、安定した噛み合い関係が得られる。   A pulley 5 that supports the ring gear 2b from the outer peripheral side is provided on the timepiece support plate 3 where the ring gear 2b meshes with the drive gear 4a of the train wheel 4. Thus, since the pulley 5 is provided in the location which meshes with the drive gear 4a of the train wheel 4, the meshing state of the location is maintained and a stable meshing relationship is obtained.

尚、輪列４は、更に第２輪列４０と噛み合い、当該第２輪列４０は、回転飾り１０を回転させるためのギア１１，１１の１つと噛み合っている。各ギア１１，１１は、時計指針軸６の箇所を回転中心とする円板ギア９に噛み合っている。   The train wheel 4 further meshes with the second train wheel 40, and the second train wheel 40 meshes with one of the gears 11 and 11 for rotating the rotary ornament 10. Each of the gears 11 and 11 meshes with a disc gear 9 whose center of rotation is the location of the watch pointer shaft 6.

このように、モータユニットＭから、輪列４、駆動歯車４ａ及びリング歯車２ｂ、つまり文字板２を回転させる駆動経路と、輪列４、第２輪列４０、ギア１１及び円板ギア９を介して他のギア１１，１１、つまり回転飾り１０，１０を回転させる駆動経路とを備えているので、後述するようにからくり動作時（各正時）に、１つのモータユニットＭにより、複数の部材（文字板２、回転飾り１０）を一度に作動させることができる（図３、図５参照）。   Thus, from the motor unit M, the train wheel 4, the drive gear 4a and the ring gear 2b, that is, the drive path for rotating the dial plate 2, the train wheel 4, the second train wheel 40, the gear 11 and the disc gear 9 are provided. Through the other gears 11, 11, that is, the driving path for rotating the rotary ornaments 10, 10. The members (the dial plate 2 and the rotating ornament 10) can be operated at a time (see FIGS. 3 and 5).

尚、図１において、時計正面下部に設けられている１１ａは、常時回転歯車で、図示を省略した別のモータにより、前記回転飾り１０，１０とは異なり、常時回転している。この常時回転歯車１１ａの存在により、時計が作動していることが示されるとともに、からくり時計の動的な趣を醸し出すことができる。   In FIG. 1, reference numeral 11 a provided at the lower part of the front face of the watch is a constantly rotating gear, which is always rotated by another motor (not shown) unlike the rotating ornaments 10 and 10. The presence of the constantly rotating gear 11a indicates that the timepiece is operating, and can create the dynamic taste of a timepiece clock.

更に、本例のからくり時計１には、第２のプーリー７が設けられている。即ち、前記リング歯車２ｂを支持する前記プーリー５は、時計指針軸６を通る仮想鉛直線を外れる位置に設けられている。この例では、プーリー５は文字板の８時に対応する箇所の時計支持板３に設けられている。そして、前記仮想鉛直線に対し線対称となる前記プーリー５の反対側の時計支持板３には、本例では文字板の４時に対応する箇所に、前記リング歯車２ｂを支持する第２のプーリー７が設けられている。   Furthermore, a second pulley 7 is provided in the mechanical clock 1 of this example. That is, the pulley 5 that supports the ring gear 2 b is provided at a position that deviates from an imaginary vertical line passing through the timepiece pointer shaft 6. In this example, the pulley 5 is provided on the timepiece support plate 3 corresponding to 8 o'clock on the dial. In addition, the timepiece support plate 3 on the opposite side of the pulley 5 that is symmetric with respect to the virtual vertical line has a second pulley that supports the ring gear 2b at a location corresponding to 4 o'clock of the dial plate in this example. 7 is provided.

このように、リング歯車を支持するプーリー５と、仮想鉛直線に対し線対称となる当該プーリー５の反対側の時計支持板３に、第２のプーリー７が設けられているので、これら第１、第２のプーリーによって、より一層文字板の保持が良好になされ得る。   Thus, since the second pulley 7 is provided on the pulley 5 that supports the ring gear and the timepiece support plate 3 on the opposite side of the pulley 5 that is axisymmetric with respect to the virtual vertical line, these first pulleys are provided. The dial can be held better by the second pulley.

また、本例のからくり時計１には、文字板の３時及び９時に対応する箇所の時計支持板３に、文字板２のリング歯車２ｂの外周縁と係合して当該文字板２を支持するプーリー８，８が設けられている。   Further, in the timepiece clock 1 of this example, the dial 2 is supported by engaging the outer peripheral edge of the ring gear 2b of the dial 2 with the clock support plate 3 corresponding to 3 o'clock and 9 o'clock of the dial. Pulleys 8, 8 are provided.

次に、本発明に係る時計飾りの脚部の嵌合および取り外し構造について図７〜図１２を参照して説明する。 Next, the fitting and detaching structure of the leg portion of the watch ornament according to the present invention will be described with reference to FIGS.

本例の飾り５０は、表面に飾り部５１を設け、この飾り部５１の裏面に脚部５２を設けている。脚部５２には、爪部５３が備えられている。   The ornament 50 of this example is provided with a decorative portion 51 on the front surface and a leg portion 52 on the back surface of the decorative portion 51. The leg portion 52 is provided with a claw portion 53.

更に、前記爪部５３は、第１傾斜部５３ａと、第２傾斜部５３ｂとを備え、更に、前記第１傾斜部５３ａと前記第２傾斜部５３ｂとの間に、前記脚部５２の圧入方向と直交する平面部５３ｃを設けている。   Further, the claw portion 53 includes a first inclined portion 53a and a second inclined portion 53b, and the leg portion 52 is press-fitted between the first inclined portion 53a and the second inclined portion 53b. A flat portion 53c orthogonal to the direction is provided.

また、時計支持板３には、飾り５０を取付ける飾り装着部３５が設けられている。飾り装着部３５には飾り５０の嵌合部３４が設けられており、この嵌合部３４には、飾り５０の爪部５３を係止する爪受け部が備えられている。   Further, the watch support plate 3 is provided with a decoration mounting portion 35 for attaching the decoration 50. The ornament mounting portion 35 is provided with a fitting portion 34 for the ornament 50, and the fitting portion 34 is provided with a claw receiving portion for locking the claw portion 53 of the ornament 50.

前記飾り５０と時計支持板３との関係は次のとおりである。すなわち、飾り５０は、時計支持板３の嵌合部３４に着脱可能に設けられるものであって、前記爪部５３は、その第１傾斜部５３ａが、嵌合部３４に圧入される際に当該嵌合部３４の前記爪受け部と摺接する。爪部５３の第２傾斜部５３ｂは、嵌合部３４に嵌合した際に前記爪受け部と摺接する。また、爪部５３の平面部５３ｃは、後述するように、飾り５０が引張られた際において、飾り５０の抜けを阻止する機能を奏する。   The relationship between the ornament 50 and the timepiece support plate 3 is as follows. That is, the decoration 50 is detachably provided on the fitting portion 34 of the timepiece support plate 3, and the claw portion 53 is formed when the first inclined portion 53 a is press-fitted into the fitting portion 34. The fitting portion 34 is in sliding contact with the claw receiving portion. The second inclined portion 53b of the claw portion 53 comes into sliding contact with the claw receiving portion when fitted into the fitting portion 34. Moreover, the flat part 53c of the nail | claw part 53 has the function which prevents the omission of the decoration 50, when the decoration 50 is pulled, so that it may mention later.

本例では、図８〜図１０に示すように、飾り５０の爪部５３は、その基部をＲ形状に形成するとともにその一対の爪部５３の基部を連結する部位を円弧状に形成している。また、飾り装着部３５は、時計支持板３から正面側へ膨出する形状に形成し、二割状の突出部とその下部に位置する嵌合部３４で構成し、嵌合部３４は通孔状の部位と、この部位の下端に、爪部５３を係止する爪受け部とを設けている。前記二割状の突出部に、爪部５３の基部が外嵌めされるので、爪部５３と嵌合部３４の装着状態が安定化され得る。   In this example, as shown in FIGS. 8 to 10, the claw portion 53 of the decoration 50 has a base portion formed in an R shape and a portion connecting the base portions of the pair of claw portions 53 formed in an arc shape. Yes. The ornament mounting portion 35 is formed in a shape that bulges from the timepiece support plate 3 to the front side, and is composed of a halved projection and a fitting portion 34 positioned below the protruding portion. A hole-shaped part and a claw receiving part for locking the claw part 53 are provided at the lower end of the part. Since the base portion of the claw portion 53 is externally fitted to the split projection portion, the mounting state of the claw portion 53 and the fitting portion 34 can be stabilized.

以上のように、本発明において、飾り５０の脚部５２が時計支持板３の嵌合部３４に挿入されると、爪部５３の第１傾斜部５３ａが、当該嵌合部３４の前記爪受け部と摺接しながら嵌め合わされ、この嵌合部３４に嵌合した際に爪部５３の第２傾斜部５３ｂが当該爪受け部と圧接しながら摺接するので、圧入された嵌合状態が具現化される。そして、飾り５０が引張られても、平面部５３ｃが設けられているので、飾り５０の爪部５３が嵌合部３４の前記爪受け部に当接して、飾り５０の抜けが阻止される。   As described above, in the present invention, when the leg portion 52 of the decoration 50 is inserted into the fitting portion 34 of the timepiece support plate 3, the first inclined portion 53 a of the claw portion 53 is moved to the claw of the fitting portion 34. Since the second inclined portion 53b of the claw portion 53 is slidably contacted with the claw receiving portion when fitted to the fitting portion 34 while being slidably contacted with the receiving portion, a press-fitted fitting state is realized. It becomes. Even when the ornament 50 is pulled, the flat portion 53c is provided, so that the claw portion 53 of the ornament 50 comes into contact with the claw receiving portion of the fitting portion 34 and the ornament 50 is prevented from coming off.

また、本例においては、脚部５２と嵌合部３４との嵌合を外すための取り外し冶具６０を用いる。そのため、支持板３の裏面側から前記取り外し冶具６０の先端を前記嵌合部３４に対し挿入可能となるように時計支持板３の飾り装着部３５の裏面には空隙部３６が設けられている。 Moreover, in this example , the removal jig | tool 60 for releasing fitting with the leg part 52 and the fitting part 34 is used. Therefore, a gap portion 36 is provided on the back surface of the ornament mounting portion 35 of the timepiece support plate 3 so that the tip of the removal jig 60 can be inserted into the fitting portion 34 from the back surface side of the support plate 3. .

この取り外し冶具６０を用いる場合、時計支持板３の飾り装着部３５の裏面に空隙部３６が設けられているので、支持板３の裏面側から、取り外し冶具６０の先端を前記嵌合部３４に挿入することができる。   When this removal jig 60 is used, the gap portion 36 is provided on the back surface of the ornament mounting portion 35 of the watch support plate 3, so that the tip of the removal jig 60 is connected to the fitting portion 34 from the back surface side of the support plate 3. Can be inserted.

更に、図１１に示すように、取り外し冶具６０は、その先端に傾斜片６１付きの窪み部６２を備える。この窪み部６２を前記一対の爪部５３，５３の前記第１傾斜部５３ａ，５３ａに摺接させれば、図１２に示すように、前記一対の脚部５２，５２を接近する方向に撓ませることができる。   Furthermore, as shown in FIG. 11, the removal jig 60 is provided with a recess 62 with an inclined piece 61 at its tip. When the recess 62 is brought into sliding contact with the first inclined portions 53a and 53a of the pair of claw portions 53 and 53, as shown in FIG. 12, the pair of leg portions 52 and 52 are bent in the approaching direction. I can do it.

このように、取り外し冶具６０の窪み部６２を前記一対の爪部５３，５３の第１傾斜部５３ａ，５３ａに摺接させて前記一対の脚部５２，５２を接近する方向に撓ませれば、飾り５０の平面部５３ｃが、嵌合部３４の前記爪受け部から外れるので、飾り５０を時計支持板３から外すことができる。   In this way, if the hollow portion 62 of the removal jig 60 is brought into sliding contact with the first inclined portions 53a and 53a of the pair of claw portions 53 and 53, the pair of leg portions 52 and 52 are bent in the approaching direction. Since the flat portion 53c of the ornament 50 is detached from the claw receiving portion of the fitting portion 34, the ornament 50 can be removed from the timepiece support plate 3.

この場合、前述したように、平面部５３ｃにおける面の間隔ｔが、当該前記一対の脚部５２，５２の部位が撓む間隔よりも小さく形成されていると、時計支持板３からの飾り５０の取り外しが円滑になされ得ることとなる。   In this case, as described above, if the surface interval t of the flat surface portion 53c is smaller than the interval at which the portions of the pair of leg portions 52, 52 are bent, the decoration 50 from the timepiece support plate 3 is used. Can be smoothly removed.

本発明は、以上の実施形態のものに限られずに、前記飾り５０は、飾り部５１の裏面に爪部５３を備えた脚部５２を設けるものであって、前記脚部５２は、時計支持板３の、爪受け部を備えた嵌合部３４に着脱可能に設けられ、前記爪部５３は、前記嵌合部３４に圧入される際に当該嵌合部３４の前記爪受け部と摺接する第１傾斜部５３ａと、当該嵌合部３４に嵌合した際に当該爪受け部と摺接する第２傾斜部５３ｂとを備え、更に、前記第１傾斜部５３ａと前記第２傾斜部５３ｂとの間に、前記脚部５２の圧入方向と直交する平面部５３ｃを設けた時計飾りの脚部の嵌合および取り外し構造であればよく、その他いかなる実施形態を施してもよいものである。 The present invention is not limited to the above embodiment, and the ornament 50 is provided with a leg portion 52 having a claw portion 53 on the back surface of the ornament portion 51, and the leg portion 52 is a timepiece support. The plate 3 is detachably provided on a fitting portion 34 having a claw receiving portion, and the claw portion 53 slides with the claw receiving portion of the fitting portion 34 when pressed into the fitting portion 34.
