Description

本発明の対象は、懐古調表示機構である。   The subject of the present invention is a nostalgic display mechanism.

ラック表示機構として知られる懐古調表示機構は、短い歯先の小歯車により駆動されるものが知られている。これらのラック機構は、軸まわりに回転するラックを備え、かつそのラックへ装着される指針を有する。ラックは、比較的大きい部材であり、すなわちこれらのラック機構は、時計においてかなりの大きさの空間を占める。渦形部材と接触するコハゼから成る多数の機構も知られている。渦形部材は、軸まわりに回転するものであり、指針へ取り付けられている。渦形部材は、表示される情報に応じて製作され、またその移動行程の最後に直線部分を有するので、コハゼが、バネの作用を受けて元の位置に戻ることができる。   An old-fashioned display mechanism known as a rack display mechanism is known to be driven by a small gear having a short tooth tip. These rack mechanisms include a rack that rotates around an axis, and have a pointer attached to the rack. Racks are relatively large members, that is, these rack mechanisms occupy a considerable amount of space in a timepiece. Numerous mechanisms are also known which consist of a goby in contact with the spiral. The spiral member rotates around an axis and is attached to the pointer. The spiral is made according to the information displayed and has a straight section at the end of its travel, so that the goby can return to its original position under the action of a spring.

本発明の目的は、確実に作動しながら殆ど空間を占めない懐古調表示機構を提供することにある。   SUMMARY OF THE INVENTION It is an object of the present invention to provide an antique display mechanism that operates reliably and occupies little space.

本発明による懐古調表示機構は、歯付き車へ装着される星車を備え、該星車は斜面をそれぞれ有する一連の先端部分を形成しており、指針へ取付けられたコハゼがバネの作用で斜面に押付けられ、斜面は、表示される情報に応じて形状とサイズが決められることを特徴とする。   The retrospective display mechanism according to the present invention comprises a star wheel mounted on a toothed wheel, the star wheel forming a series of tip portions each having a slope, and a kohaze attached to the pointer is operated by a spring. The slope is pressed against the slope, and the shape and size of the slope are determined according to displayed information.

好ましい実施例において、コハゼ、指針およびバネは、軸まわりに回転するバレルに取付けられる。また、コハゼが斜面に対するその移動行程の最後に達して別のサイクルのために次の斜面に落込んだ後の、バネの作用によるバレルの巻戻しをストッパ部材が阻止する。   In a preferred embodiment, the goby, pointer and spring are mounted on a barrel that rotates about an axis. Also, the stopper prevents the barrel from being unwound by the action of the spring after the goby has reached the end of its travel on the slope and falls on the next slope for another cycle.

星車の先端部分の斜面は、線形（linear）な表示を与える形状にすることができる。   The slope at the tip of the star wheel can be shaped to give a linear display.

図面は、一例として、本発明に従う懐古調表示機構の１つの実施例を示す。   The drawings show, by way of example, one embodiment of a nostalgic display mechanism according to the present invention.

図面の図１乃至４は、単純化された懐古調表示機構を示す。時計製作において、この表示機構は、例えば、時計の動力蓄積量、またはこの場合には中央秒針を表示するのに使用される。その表示機構は、ジャンプしないという利点を有する。指針は、従来技術の多くの懐古調ムーブメントと異なり、常時動いている。   Figures 1-4 of the drawings show a simplified retrospective display mechanism. In watchmaking, this display mechanism is used, for example, to display the power reserve of the watch, or in this case the central second hand. The display mechanism has the advantage of not jumping. The pointer is constantly moving, unlike many retrograde movements of the prior art.

この機構は、
懐古調の星車１、
渦巻き状のバネ２、
懐古調のコハゼ３、
渦巻きバネの固定用ピン４、
ストッパピン５、および
指針６、を有する。 This mechanism is
Nostalgic star wheel 1,
Spiral spring 2,
Nostalgic kohaze 3,
Pin 4 for fixing spiral spring,
It has a stopper pin 5 and a pointer 6.

この懐古調機構は、歯つき車すなち歯車Ｒ１とＲ２により駆動される。懐古調の星車１は歯車Ｒ２へ取り付けられており、またその周辺に等間隔で離間する幾つかの同一形状の先端部分を有する。   This nostalgic mechanism is driven by a toothed wheel, ie, gears R1 and R2. The retro star wheel 1 is mounted on a gear R2 and has several identically shaped tips around its circumference.

懐古調コハゼ３の先端部分は、星車１の先端部分と常に接触しており、かつ上述の先端部分の斜面Ｂに押付けられている。渦巻き状のバネ２は、この常時の接触を維持する。軸Ａの断面（図２）により、この機構を詳細に示す。渦巻き状のバネ２は、バレル７へ取り付けられている。同様に、懐古調のコハゼ３および指針６は、バレル７へ圧嵌されている。バレル７は、軸Ａまわりに自由である。固定用ピン４は、渦巻き状のバネ２の保持に利用されている。   The tip of the old-fashioned kohaze 3 is always in contact with the tip of the star wheel 1 and is pressed against the slope B of the tip. The spiral spring 2 maintains this constant contact. The mechanism is shown in more detail by a cross section of axis A (FIG. 2). The spiral spring 2 is attached to a barrel 7. Similarly, the old-fashioned kohaze 3 and the pointer 6 are pressed into the barrel 7. The barrel 7 is free around the axis A. The fixing pin 4 is used for holding the spiral spring 2.

作動中、懐古調可動部材すなわち歯車Ｒ２は、時計方向に回転して、斜面Ｂにより懐古調のコハゼ３の先端部分を駆動する。その先端部分がその移動行程の最後に達すると（図３）、斜面Ｂはコハゼ３から離脱して、コハゼ３が次の斜面Ｃ上に落ち込む。この動作は、斜面Ｃから次の斜面へ繰返される。かくして指針６は、常に移動を行う。ストッパピン５は、落ち込みの際のストッパ部材として作用し、コハゼ３の先端部分が、星車１の形状の底部へ落ち込むのを防止する。   In operation, the nostalgic movable member or gear R2 rotates clockwise to drive the tip of the nostalgic kohaze 3 by the slope B. When its tip reaches the end of its travel (FIG. 3), slope B separates from kohaze 3 and kohaze 3 falls onto the next slope C. This operation is repeated from the slope C to the next slope. Thus, the pointer 6 always moves. The stopper pin 5 functions as a stopper member at the time of dropping, and prevents the tip portion of the kohaze 3 from dropping to the bottom of the star wheel 1.

星車１の先端部分の斜面Ｂ、Ｃは、指針６が、図示されない文字板上を線形に（linearly）移動するよう入念に設計されている。   The slopes B and C at the tip of the star wheel 1 are carefully designed so that the pointer 6 moves linearly on a dial (not shown).

図２に示されるように、渦巻き状のバネ２、懐古調のコハゼ３および指針６は、バレル７へ圧嵌されており、その結果、上述のバレル７に対する位置をそれぞれ固定されている。   As shown in FIG. 2, the spiral spring 2, the old-fashioned kohaze 3, and the pointer 6 are press-fitted to the barrel 7, and as a result, their positions with respect to the barrel 7 are fixed.

渦巻き状のバネ２は、固定用ピン４により引っ張りを与えられて機構のフレームへ固定されている。図１に示されるように、指針６は、その移動行程の初期において、停止部材すなわちストッパピン５に対面しており、また懐古調のコハゼ３も、その移動行程の初期において、懐古調の星車１の先端部分の斜面Ｂと接触している。歯車Ｒ２へ取付けられた星車１は、可動部材すなわち歯車Ｒ１により矢印の方向（図１と３を参照）に駆動され、ついで今度はコハゼ３を駆動し、そのコハゼ３は、歯車Ｒ１が回転すると、星車１の先端部分の斜面Ｂに沿って移動する。コハゼ３に対して固定位置にある指針６は、バネ２の作用に抗して上述のコハゼ３により駆動され、図示されない文字板上に表示される値を指示する。コハゼ３が図３に示される位置を越えて移動すると、バネ２は、コハゼ３と指針６とを、それらの元の位置に戻して、ストッパピン５に押付け、このサイクルを星車１の斜面Ｃについて再び開始できる。   The spiral spring 2 is tensioned by a fixing pin 4 and is fixed to the frame of the mechanism. As shown in FIG. 1, the pointer 6 faces the stop member or the stopper pin 5 at the beginning of its travel, and the nostalgic kohaze 3 also has a nostalgic star at the beginning of its travel. It is in contact with the slope B at the tip of the car 1. The star wheel 1 mounted on the gear R2 is driven by the movable member or gear R1 in the direction of the arrow (see FIGS. 1 and 3), which in turn drives the kohaze 3, which rotates the gear R1. Then, it moves along the slope B at the tip of the star wheel 1. The pointer 6 at a fixed position with respect to the kohaze 3 is driven by the above-mentioned kohaze 3 against the action of the spring 2 and indicates a value displayed on a dial (not shown). When the goby 3 moves beyond the position shown in FIG. 3, the spring 2 returns the goby 3 and the pointer 6 to their original positions and presses them against the stopper pins 5, and this cycle is performed on the slope of the star wheel 1. We can start again for C.

図１乃至４を参照して上述した機構は、秒、分、時、日付、曜日および月相などの、時計により通常表示される任意の種類の情報を指示するようにすることができる。可動部材すなわち歯車Ｒ１とＲ２は、適切な寸法を有するようにしなければならないし、また星車１の先端部分は、表示される値に適合される。   The mechanism described above with reference to FIGS. 1-4 can indicate any type of information normally displayed by a clock, such as seconds, minutes, hours, dates, days of the week, and moon phases. The movable members or gears R1 and R2 must have suitable dimensions and the tip of the star wheel 1 is adapted to the values indicated.

上述の機構は、単純であるという利点、および常に移動する表示を形成するという利点を提供する。コハゼが星車の先端部分を通過するやいなや、次のサイクルが開始し、表示が中断無しに継続される。   The mechanism described above offers the advantage of being simple and of forming a constantly moving display. As soon as the kohaze passes over the tip of the star wheel, the next cycle starts and the display continues without interruption.

本発明の一実施例による懐古調表示機構の平面図である。FIG. 2 is a plan view of the retro display mechanism according to the embodiment of the present invention. 表示機構における指針を保持する軸を通る断面図である。It is sectional drawing which passes through the axis | shaft holding the pointer | indication in a display mechanism. 懐古調コハゼが指針のリセット前の最終位置にある、図１と同様な図である。FIG. 2 is a view similar to FIG. 1, wherein the retro-styled kohaze is in a final position before resetting the hands. 懐古調星車の平面図である。It is a top view of a nostalgic star wheel.
