上述した文字板が上下動する構造のからくり時計において、文字板の上下駆動にリンク部材を用いることが知られている。この場合、リンク部材は、文字板を駆動させるもの（駆動用リンク部）と、その文字板の駆動を保持するもの（支持用リンク部）が用いられるところ、文字板が閉まった位置におけるリンク部材（駆動用リンク部および支持用リンク部）とこれに係合する文字板との間に、文字板の開閉動作、とりわけ開動作がスムーズに行われるように、アガキ（ガタツキ）を設けている。 It is known that a link member is used to drive the dial up and down in the above-described mechanism clock structure in which the dial moves up and down. In this case, the link member is one that drives the dial (driving link portion) and one that holds the drive of the dial (supporting link portion), and the link member at the position where the dial is closed. Between the (driving link portion and supporting link portion) and the dial engaged therewith, an opening (backlash) is provided so that the opening / closing operation of the dial, particularly the opening operation, is performed smoothly.

ところが、上述したアガキは、文字板が閉まった際に、文字板とリンク部材との間に、前後および左右方向のガタツキを許容するため、文字板の自重でリンク部材が斜めに偏位することがある。このようにリンク部材が偏位すると、文字板の動作開始の際に、文字板の動作に不具合を生じるおそれがある。 However, since the above-described postcard allows backlash in the front-rear and left-right directions between the dial and the link member when the dial is closed, the link member is displaced obliquely by the weight of the dial. There is. If the link member is displaced in this way, there is a possibility that a malfunction may occur in the operation of the dial plate when the operation of the dial plate is started.

以下に、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

本例における時計１００のからくり構造は、図１〜図７に示すように、例えば正時にモータＭが正転して、文字板１０（１１，１２）が上下動作するものである。すなわち、本例の文字板１０は、左右に二分割された一対の文字板（分割文字板１１，１２）であり、これらの分割文字板１１，１２は、図１および図４に示す位置から、それぞれ左右に拡開しながら（図２および図５）半円弧状の軌跡（図７の矢印参照）を辿って下方へ移動し、下方で合体する（図３および図６）。爾後、この軌跡を辿って上方へ移動し、再び当初の位置に復帰するように構成されている。なお、図中、符号３は時計筐体、符号４は装飾体である。 As shown in FIGS. 1 to 7, the mechanism structure of the timepiece 100 in this example is one in which the motor M rotates forward at normal time and the dial 10 (11, 12) moves up and down. That is, the dial plate 10 of this example is a pair of dial plates (divided dial plates 11 and 12) divided into right and left, and these divided dial plates 11 and 12 are located from the positions shown in FIGS. Then, while expanding left and right (FIGS. 2 and 5), they follow a semicircular arc-like locus (see the arrow in FIG. 7), move downward, and merge at the bottom (FIGS. 3 and 6). Thereafter, the robot follows the trajectory, moves upward, and returns to the original position again. In the figure, reference numeral 3 denotes a watch housing and reference numeral 4 denotes a decorative body.

モータＭの駆動力は、図８〜図１０に示すように、モータＭおよびモータユニット５に連係する輪列６、連係歯車７、終端歯車８に駆動伝達される。そして、文字板１０（１１，１２）の上下動作は、後述する駆動用リンク部３０を介して、行われる。なお、本例の場合は、さらに、終端歯車８に噛合する当該終端歯車と同形状の補助歯車９を用いて、各々別に分割文字板１１，１２の上下動作が行われる。 As shown in FIGS. 8 to 10, the driving force of the motor M is transmitted to the gear train 6, the linkage gear 7, and the terminal gear 8 linked to the motor M and the motor unit 5. The vertical movement of the dial 10 (11, 12) is performed via a drive link unit 30 described later. In the case of this example, the divided dials 11 and 12 are moved up and down separately using the auxiliary gear 9 having the same shape as the terminal gear meshing with the terminal gear 8.

文字板１０（１１，１２）は、文字板支持用のリンク部たる支持用リンク部２０によって上述した半円弧状の軌跡を確実に辿るように保持されている。そして、分割文字板１１，１２には、中央の分割部位に対し、支持用リンク部２０および駆動用リンク部３０が左右対称に配置されている。これにより、分割文字板１１，１２は、中央の分割部位に対し、左右対称に動作する。 The dial plate 10 (11, 12) is held so as to surely follow the semicircular arc-shaped locus described above by the support link portion 20 which is a link portion for supporting the dial plate. In the divided dial plates 11 and 12, the support link portion 20 and the drive link portion 30 are arranged symmetrically with respect to the central divided portion. Thereby, the divided dial plates 11 and 12 operate symmetrically with respect to the central divided portion.

図１１〜図１４に示すように、支持用リンク部２０は、その一端部２１が、文字板１０（１１，１２）の裏面に回転可能に取付けられる。同様に、駆動用リンク部３０も、その一端部３１が文字板１０（１１，１２）の裏面に回転可能に取付けられる。 As shown in FIGS. 11 to 14, one end 21 of the support link portion 20 is rotatably attached to the back surface of the dial 10 (11, 12). Similarly, the drive link portion 30 is also rotatably attached at its one end 31 to the back surface of the dial 10 (11, 12).

本例の場合、文字板１０（１１，１２）の裏面に、リング状に突出する外側リング部１３と、内側リング部１４、中央にボス部１５を形成している。そして、これに対応させて、支持用リンク部２０の一端部２１と駆動用リンク部３０の一端部３１にはそれぞれ外側リング部２３，３３、内側リング状突出部２４，３４を形成し、これらの間にプーリ５０を装着して、座付きネジ６０で、文字板１０（１１，１２）と、支持用リンク部２０の一端部２１および駆動用リンク部３０の一端部３１とを、回転可能に結合している。 In the case of this example, an outer ring portion 13 protruding in a ring shape and an inner ring portion 14 are formed on the back surface of the dial 10 (11, 12), and a boss portion 15 is formed at the center. Correspondingly, outer ring portions 23 and 33 and inner ring-shaped protruding portions 24 and 34 are formed at one end portion 21 of the support link portion 20 and one end portion 31 of the drive link portion 30, respectively. The pulley 50 is mounted between the two, and the dial 10 (11, 12) and the one end portion 21 of the support link portion 20 and the one end portion 31 of the drive link portion 30 can be rotated with a seated screw 60. Are connected.

支持用リンク部２０の他端部２２は、時計支持板（中板１）に設けたボス部（図示を省略）に回転可能に取付けられる。また、駆動用リンク部３０の他端部３２は、図１５に示すように、終端歯車８または補助歯車９の中央部に固着される。 The other end portion 22 of the support link portion 20 is rotatably attached to a boss portion (not shown) provided on the timepiece support plate (middle plate 1). Further, the other end portion 32 of the drive link portion 30 is fixed to the central portion of the terminal gear 8 or the auxiliary gear 9 as shown in FIG.

さらに本例では、図１２〜図１４および図１６に示すように、複数のリンク部２０，３０の前記一端部２１，３１が回転可能に取付けられる箇所における文字板１０の裏面に、テーパ面１６ａを設けた突部１６を形成している。また、リンク部２０，３０の前記一端部２１，３１には、文字板１０の前記テーパ面１６ａに当接するテーパ面２５ａ，３５ａを設けた突部２５，３５を形成している。 Furthermore, in this example, as shown in FIGS. 12 to 14 and FIG. 16, a tapered surface 16 a is formed on the back surface of the dial plate 10 at a position where the one end portions 21, 31 of the plurality of link portions 20, 30 are rotatably attached. The protrusion 16 provided with is formed. Further, the end portions 21 and 31 of the link portions 20 and 30 are formed with protruding portions 25 and 35 provided with tapered surfaces 25a and 35a that come into contact with the tapered surface 16a of the dial plate 10, respectively.

上記のように構成される本例の時計１００において、例えば正時に図示を省略した制御部から駆動信号が送られて、モータＭが正転すると、これに連係する輪列６および連係歯車７が駆動し、終端歯車８と補助歯車９が回転する。同時に、終端歯車８および補助歯車９に固着されている駆動用リンク部３０が回動し、この駆動用リンク３０により文字板１０（１１，１２）が半円弧の軌跡を形成して下降する。文字板１０の下降に伴い、文字板１０の突部１６に設けたテーパ面１６ａと、リンク部２０，３０の突部２５，３５に設けたテーパ面２５ａ，３５ａは離反して行く。 In the timepiece 100 of the present example configured as described above, for example, when a drive signal is sent from a control unit (not shown) at the normal time and the motor M rotates in the forward direction, the train wheel 6 and the linked gear 7 that are linked thereto are Driven, the terminal gear 8 and the auxiliary gear 9 rotate. At the same time, the drive link 30 fixed to the terminal gear 8 and the auxiliary gear 9 is rotated, and the dial 10 (11, 12) is lowered by the drive link 30 while forming a semicircular locus. As the dial 10 is lowered, the tapered surface 16a provided on the protrusion 16 of the dial 10 and the tapered surfaces 25a and 35a provided on the protrusions 25 and 35 of the link portions 20 and 30 are separated from each other.

モータＭが反転すると、輪列６の終端歯車８が反転して、文字板駆動用のリンク部（駆動用リンク部３０）を作動させて文字板１０を上昇させ、当該文字板１０が元の位置に戻った際に、リンク部２０，３０の突部２５，３５に設けたテーパ面２５ａ，３５ａが、文字板１０の突部１６に設けた前記テーパ面１６ａに当接する。 When the motor M is reversed, the terminal gear 8 of the train wheel 6 is reversed, the dial driving link portion (driving link portion 30) is operated to raise the dial 10, and the dial 10 is restored to its original position. When returning to the position, the taper surfaces 25 a and 35 a provided on the projections 25 and 35 of the link portions 20 and 30 abut on the taper surface 16 a provided on the projection 16 of the dial 10.

このように、文字板が下降した後にモータが反転すると文字板が上昇し、さらに文字板が元の位置に戻った際に、リンク部の突部に設けたテーパ面が、文字板の突部に設けたテーパ面に当接するので、リンク部の動きが、前後および左右方向において規制され、これにより文字板の上昇下降により生じ得るリンク部材の動作の不具合を回避することができるようになる。 Thus, when the motor is reversed after the dial is lowered, the dial is raised, and when the dial is returned to the original position, the tapered surface provided on the projection of the link portion is the projection of the dial. Therefore, the movement of the link portion is restricted in the front-rear direction and the left-right direction, so that it is possible to avoid the malfunction of the link member that may be caused by the rising and lowering of the dial.

さらに、本例のように、分割文字板１１，１２に、支持用リンク部２０および駆動用リンク部３０を左右対称に配置し、さらに終端歯車８と補助歯車９を設けて、分割文字板１１，１２が左右対称に偏心回転動作するように構成した場合は、からくり効果の著効性も一層高まるものとなる。 Further, as in this example, the divided dial plates 11 and 12 are provided with the support link portion 20 and the drive link portion 30 symmetrically arranged, and further provided with the terminal gear 8 and the auxiliary gear 9, and the divided dial plate 11. , 12 are configured to be eccentrically rotated in a bilaterally symmetrical manner, the remarkable effect of the Karakuri effect is further enhanced.

本発明のからくり時計は、リンク部材を設けてもその動作の不具合を回避できて動作の安定化に優れ、また、からくり効果にも優れたものであり、壁掛け時計などの時計一般に好適に利用することができるものである。 Even if a link member is provided, the mechanical clock of the present invention is capable of avoiding malfunctions of the operation, is excellent in stabilizing the operation, and is excellent in the mechanical effect, and is suitably used for a general clock such as a wall clock. It is something that can be done.
