Definitions
- the invention relates to a mechanism for moving an indicator of a clock according to the preamble of the independent claim.
- the invention relates to a mechanism for driving a clock hand, which is moved from one extreme position to another extreme position and then reset in the same way, without making a complete turn.
- the pointer stands in each case in certain positions of a scale to indicate a date or a time.
- CH-A3-666 591 discloses in a general form such a mechanism, which consists essentially of a cam which is connected to a star-shaped pinion. Both are arranged around an axis and rotate about this axis.
- the star-shaped pinion which has seven prongs and rotates gradually, is held in this position at any position by a lever which engages in the indentations of the prongs.
- seven different positions of the cam are established, and one finger of a rake, which is frictionally connected to the cam, slides along the contour of the cam and adapts to the contour.
- the contour of the cam is designed so that there are seven different positions, which have a slightly different level than the rest of the contour, so that the finger finds support.
- the rake thus shifts piecemeal and the teeth of the rake, which engage the teeth of a pinion of the pointer, move the pointer, which shifts in a corresponding manner in each case by a corresponding angle.
- the pointer is with a pen connected, which resets the pointer and generates a force acting on the pointer and the rake.
- US-A-5,043,955 also discloses such a mechanism wherein four rakes are arranged around a single central cam.
- the four rakes each drive a pointer, which are arranged at the four corners of a square clock.
- the rakes are pressed onto the contour of the cam with a spring.
- the spring has two legs and is attached to a point.
- EP-A1-1 102 134 discloses a watch with such a mechanism, wherein two rakes are arranged around a central cam.
- the peculiarity here is that the rake consist of two legs, one leg is positively connected to the contour of the cam and the second leg has teeth that adjust the pointer. Both legs converge at a common point and are pivotally mounted about this point.
- US-A-2,292,458 discloses a similar mechanism which additionally provides a linear displacement of two pointers.
- Another embodiment is in CH-A5-691 087 disclosed.
- a second rake is provided to compensate for the play between the teeth of a first rake and the teeth of the pinion.
- the rake is provided on the other side of the pinion and exerts a force on the pinion, which is opposite to the force of the first pinion.
- it is less advantageous in this arrangement that it occupies a lot of space, since the rakes are arranged on two different sides of the pinion. Due to the size of the cam disk, hardly any geometric changes are possible to transfer the system to another application.
- EP-A1-1 555 584 also known to modify the teeth. Through certain gaps and gaps, the teeth can adapt to the particular application and reduce the game to some extent.
- FR-A-2,863,368 discloses a mechanism for displaying a moon phase. Two discs are moved between two extreme positions by two rakes. Both rakes are stored around a common point and are stirred by a pinion. Both rakes attack the pinion from a different side.
- the embodiment has the advantage that it saves space and the rake each other by the overlapping arrangement stabilize. This can be supported by an additional fixation, which has a certain play.
- an additional fixation which has a certain play.
- a game and vibrations when changing the position of the indicator can be avoided. This is thus at a fixed position, even if the clock is moved by the user.
- the rakes can also be pivotally mounted about the one common axis, which has the advantage that an additional axis and associated fasteners omitted.
- the pitch of the teeth and also the modulus of the two rakes may be different in both rakes, so that the designer advantageously has an extra degree of freedom in designing a particular embodiment.
- the second rake can exert force on the pinion, it is positively connected to a spring, which acts on a recess of the second rake, which is arranged on a side opposite the cam.
- the spring may have two legs and be mounted on a fixed point.
- the cam which is connected to a pinion, has a contour, so that the first rake remains in a plurality of discrete positions upon rotation of the cam.
- the cam is a worm and consists of two offset ellipsoid or semicircle-like elements, wherein between the elements a jump in the contour of the cam is present.
- one or both rakes and also the pinion which drives the indicator may be made of a plastic. Further advantageous embodiments are specified in the subclaims.
- the FIG. 1 shows a mechanism 1 according to the invention for moving an indicator of a clock, which moves from one extreme position to another extreme position and is then reset in the same way, without making a full revolution of 360 °.
- the scoreboard in the FIG. 1 is not shown, is connected to the pinion 7 and stands in each case in certain positions of a scale to indicate a day of the week, a date, a time, seconds, etc.
- the FIG. 1 shows the mechanism at a maximum position right after the indicator reset.
- the indicator may be a clock hand, such as a retrograde clock hand, or a dial partially visible through a window of the clock.
- the mechanism consists of a cam 2, which is connected to a star 3, which drives it.
- the cam is a worm.
- the cam 2 has a contour 21 and consists in the embodiment shown of two staggered, ellipsoidal or semi-circular elements, wherein between the two elements a jump 22 in the contour 21 of the cam 2 is present.
- the star 3 and the cam 2 rotate about a common axis A.
- the star 3 is driven by an actuator 32, which has a nose, and held in any particular position by a lever spring 31.
- a first rake 4 is positively connected to the cam plate 2.
- the rake 4, which is mounted pivotably about an axis B, has teeth 41 on one side.
- the rake 4 On the side facing the cam 2, the rake 4 has an L-shaped recess 42 which forms a finger 43 at a portion.
- the finger 43 which is also partially equipped with the teeth 41, frictionally rests on the contour 21 of the cam 2.
- the contour 21 of the cam 2 has a plurality of slight dents or points of slightly lower level, so that the first rake 4 stops at a rotation of the cam 2 in a plurality of discrete positions. In the embodiment shown, seven segments and positions are provided per element, each of which represents a day of the week. Overall, thus arise on the cam 2 fourteen elements.
- the number of dents or positions and the specific embodiment of the cam 2 the contour 21 and the jumps 22 may vary according to the given example and the value to be displayed.
- the pinion 7 thus drives the clock hand or the disc.
- the pinion 7 has a number of teeth 71 which engage in the teeth 41 of the first rake 4.
- the pinion 7 rotates about an axis C.
- the teeth 41 of the rake 4 rest on one side on the teeth 71 of the pinion 7 and thus transmit a force.
- each ellipsoidal or semicircular element of the cam 2 with respect to the axis A has an increasing radius
- the finger 43 shifts continuously during rotation of the cam 2 and the pinion 7 rotates counterclockwise, as indicated by the arrow in FIG of the Fig. 1 is indicated.
- the positions present on the contour 21 are transferred to the positions of the pointer to be displayed.
- Fig. 2 shows the mechanism 1, after the cam 2 has circulated half a turn.
- the finger 43 is located immediately before the jump 22 and thus at a second extreme position, just before the indicator to the position in the Fig. 1 is shown, is reset in one step in a clockwise direction.
- a second rake 5 is arranged overlapping the first rake 4.
- the embodiment has the advantage that it is space-saving and the rakes stabilize each other by the overlapping arrangement.
- the rake 5 has teeth 51, which also engage in the teeth 71 of the pinion 7.
- the second rake 5 is pivotally mounted together with the rake 4 about the first axis B and both elements 4, 5 are connected by a fixing 44, 54 with each other, which holds the two rakes 4, 5 together.
- the rake 5 additionally has a guide 53.
- the second rake 5 exerts a force on the teeth 71 of the pinion 7, which is opposite to the force exerted by the first rake 4 on the pinion 7.
- This force alone would thus rotate the pinion 7 in a clockwise direction.
- the teeth 51 abut on the side of the teeth 71 at which the mentioned clearance between the second side of the teeth 41 and the teeth 71 of the pinion 7 is present.
- a spring 6 is positively connected to it.
- the spring 6 is arranged in a parallel plane to the rake and on the side of the rake 5, which is opposite to the cam plate 2. On this side, the rake 5 has a recess 52, can act on the spring 6.
- the spring 6 has two legs 61 and is mounted on a fixed point 62, on which both legs 61 converge.
- a leg 61 is held by a fastening 63.
- Other springs or power transmission elements are also conceivable within the scope of the invention.
- the pitch of the teeth 41, 51 and also the modulus of the two rakes 4, 5 may be different in both rakes 4, 5, so that the designer advantageously has an additional degree of freedom in the design of a specific embodiment of the inventive mechanism.
- one or both rakes 4, 5 and also the pinion 7 may be made of a plastic. This is especially true for the rake 5, which can be manufactured as a standard part and thus can work together in different movements with first, for example metallic rake 4 different size, pitch and / or modules.

Es ist ein Ziel der Erfindung, ein Mechanismus zur Bewegung eines Anzeigers einer Uhr zu schaffen, der platzsparender als aus dem Stand der Technik bekannte Mechanismen ist.It is an object of the invention to provide a mechanism for moving an indicator of a timepiece which is more space efficient than mechanisms known in the art.
Es ist ein anderes Ziel der Erfindung, ein Mechanismus zur Bewegung eines Anzeigers einer Uhr zu schaffen, der das Spiel zwischen den Zähnen eines Rechen und den Zähnen eines Ritzel bei einem eingangs erwähnten Mechanismus eliminiert oder weitgehend reduziert.It is another object of the invention to provide a mechanism for moving an indicator of a watch, which eliminates or substantially reduces the play between the teeth of a rake and the teeth of a pinion in a mechanism mentioned in the introduction.
Es ist ein weiteres Ziel der Erfindung, ein Mechanismus zur Bewegung eines Anzeigers einer Uhr zu schaffen, der den Konstrukteur einen grösseren Freiheitsgrad bei der Auslegung lässt als aus dem Stand der Technik bekannte Mechanismen.It is a further object of the invention to provide a mechanism for moving an indicator of a timepiece which allows the designer a greater degree of freedom in design than mechanisms known from the prior art.
Erfindungsgemäss werden diese Ziele bei einem Mechanismus zur Bewegung eines Anzeigers einer Uhr gemäss dem Oberbegriff des unabhängigen Anspruchs dadurch die kennziechnenden meckmale gelöst.According to the invention, these objects are achieved in a mechanism for moving an indicator of a clock according to the preamble of the independent claim thereby the kennckchnenden meckmale.
Die Ausführungsform hat den Vorteil, dass sie Platz sparend ist und die Rechen sich durch die überlappende Anordnung gegenseitig stabilisieren. Die kann durch eine zusätzliche Fixierung, die ein gewisses Spiel aufweist, unterstützt werden. Durch den erfindungsgemässen Mechanismus werden ein Spiel und Schwingungen beim Wechseln der Position des Anzeigers vermieden. Dieser steht somit an einer festen Position, auch wenn die Uhr durch den Benutzer bewegt wird.The embodiment has the advantage that it saves space and the rake each other by the overlapping arrangement stabilize. This can be supported by an additional fixation, which has a certain play. By the inventive mechanism, a game and vibrations when changing the position of the indicator can be avoided. This is thus at a fixed position, even if the clock is moved by the user.
Die Rechen können auch um die eine gemeinsame Achse schwenkbar gelagert sein, was den Vorteil aufweist, dass eine zusätzliche Achse und damit verbundene Befestigungen entfallen. Die die Teilung der Zähne und auch der Modul der beiden Rechen kann bei beiden Rechen unterschiedlich sein, so dass der Konstrukteur vorteilhaft einen zusätzlichen Freiheitsgrad bei der Auslegung einer bestimmten Ausführungsform hat.The rakes can also be pivotally mounted about the one common axis, which has the advantage that an additional axis and associated fasteners omitted. The pitch of the teeth and also the modulus of the two rakes may be different in both rakes, so that the designer advantageously has an extra degree of freedom in designing a particular embodiment.
Damit der zweite Rechen Kraft auf das Ritzel ausüben kann, ist er kraftschlüssig mit einer Feder verbunden, die auf eine Aussparung des zweiten Rechens einwirkt, welche an einer der Kurvenscheibe gegenüberliegenden Seite angeordnet ist. Die Feder kann zwei Schenkel aufweisen und an einen Fixpunkt gelagert sein.So that the second rake can exert force on the pinion, it is positively connected to a spring, which acts on a recess of the second rake, which is arranged on a side opposite the cam. The spring may have two legs and be mounted on a fixed point.
Die Kurvenscheibe, die mit einem Ritzel verbunden ist, weist eine Kontur auf, so dass der erste Rechen bei einer Drehung der Kurvenscheibe in mehreren diskreten Positionen stehen bleibt. In einer konkreten Ausführungsform ist die Kurvenscheibe eine Schnecke und besteht aus zwei versetzten ellipsoiden oder halbkreisähnlichen Elementen, wobei zwischen den Elementen ein Sprung in der Kontur der Kurvenscheibe vorhanden ist.The cam, which is connected to a pinion, has a contour, so that the first rake remains in a plurality of discrete positions upon rotation of the cam. In a specific embodiment, the cam is a worm and consists of two offset ellipsoid or semicircle-like elements, wherein between the elements a jump in the contour of the cam is present.
Zur einfacheren Herstellung können ein oder beide Rechen und auch das Ritzel, welches den Anzeiger antreibt, aus einem Kunststoff hergestellt sein. Weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen angegeben.For ease of manufacture, one or both rakes and also the pinion which drives the indicator may be made of a plastic. Further advantageous embodiments are specified in the subclaims.

Die
Der Mechanismus besteht aus einer Kurvenscheibe 2, die mit einem Stern 3 verbunden ist, welches sie antreibt. Im speziellen Fall, der in der
Kraftschlüssig mit der Kurvenscheibe 2 verbunden ist ein erster Rechen 4. Der Rechen 4, der um eine Achse B schwenkbar gelagert ist, weist an einer Seite Zähne 41 auf. An der Seite, die der Kurvenscheibe 2 zugewandt ist, weist der Rechen 4 eine L-förmige Aussparung 42 auf, die an einem Abschnitt einen Finger 43 bildet. Der Finger 43, der teilweise auch mit den Zähnen 41 ausgestattet ist, liegt kraftschlüssig auf der Kontur 21 der Kurvenscheibe 2 auf. Die Kontur 21 der Kurvenscheibe 2 weist eine Vielzahl von leichten Eindellungen oder Stellen von etwas geringerem Niveau auf, so dass der erste Rechen 4 bei einer Drehung der Kurvenscheibe 2 in mehreren diskreten Positionen stehen bleibt. Im gezeigten Ausführungsbeispiel sind pro Elemente sieben Segmente und Positionen vorgesehen, die jeweils für einen Wochentag stehen. Insgesamt ergeben sich somit an der Kurvenscheibe 2 vierzehn Elemente. Selbstverständlich können die Anzahl der Eindellungen bzw. Positionen und die konkrete Ausführungsform der Kurvenscheibe 2, der Kontur 21 und der Sprünge 22 entsprechend dem vorgegebenen Beispiel und dem anzuzeigenden Wert variieren.A
Gleichzeitig ist ein Ritzel 7 mit einem in der
Dadurch, dass je ein ellipsoides oder halbkreisähnliches Element der Kurvenscheibe 2 in Bezug auf die Achse A einen ansteigenden Radius ausweist, verschiebt sich der Finger 43 während der Drehung der Kurvenscheibe 2 stetig und das Ritzel 7 dreht sich entgegen dem Uhrzeigersinn, wie mit dem Pfeil in der
Erfindungsgemäss wird ein zweiter Rechen 5 überlappend mit dem ersten Rechen 4 angeordnet. Die Ausführungsform hat den Vorteil, dass sie Platz sparend ist und die Rechen sich durch die überlappende Anordnung gegenseitig stabilisieren. Der Rechen 5 weist Zähne 51 auf, die ebenfalls in die Zähne 71 des Ritzels 7 eingreifen. Im gezeigten Ausführungsbeispiel ist der zweite Rechen 5 zusammen mit dem Rechen 4 um die erste Achse B schwenkbar gelagert und beide Elemente 4, 5 werden durch eine Fixierung 44, 54 miteinander verbunden, die die beiden Rechen 4, 5 aneinander hält. Es wäre jedoch im Rahmen der Erfindung auch denkbar, eine davon unabhängige Achse vorzusehen. Wenn wie gezeigt die Rechen um die eine gemeinsame Achse B schwenkbar gelagert sind, hat das den Vorteil, dass eine Achse und damit verbundene Befestigungen entfallen. Der Rechen 5 weist zusätzlich eine Führung 53 auf.According to the invention, a
Durch die gezeigte Anordnung übt der zweite Rechen 5 eine Kraft auf die Zähne 71 des Ritzels 7 aus, die der Kraft, die der erste Rechen 4 auf das Ritzel 7 ausübt, entgegengesetzt ist. Diese Kraft allein würde das Ritzel 7 somit im Uhrzeigersinn drehen. Somit liegen die Zähne 51 an der Seite der Zähne 71 an, an der das erwähnte Spiel zwischen der zweiten Seite der Zähne 41 und den Zähnen 71 des Ritzels 7 vorhanden ist. Damit der Rechen 5 diese Kraft ausüben kann, ist eine Feder 6 kraftschlüssig mit ihm verbunden. Die Feder 6 ist in einer parallelen Ebene zum Rechen und an der Seite des Rechens 5 angeordnet, die der Kurvenscheibe 2 gegenüberliegt. An dieser Seite weist der Rechen 5 eine Aussparung 52 auf, auf die Feder 6 einwirken kann. Im gezeigten Beispiel weist die Feder 6 zwei Schenkel 61 auf und ist an einem Fixpunkt 62 gelagert, an dem beide Schenkel 61 zusammenlaufen. Ein Schenkel 61 wird von einer Befestigung 63 gehalten. Andere Federn oder Kraftübertragungselemente sind aber im Rahmen der Erfindung ebenso denkbar.By the arrangement shown, the
Die die Teilung der Zähne 41, 51 und auch der Modul der beiden Rechen 4, 5 kann bei beiden Rechen 4, 5 unterschiedlich sein, so dass der Konstrukteur vorteilhaft einen zusätzlichen Freiheitsgrad bei der Auslegung einer bestimmten Ausführungsform des erfindungsgemässen Mechanismus hat. Zur einfacheren Herstellung können ein oder beide Rechen 4, 5 und auch das Ritzel 7 aus einem Kunststoff hergestellt sein. Dies gilt insbesondere für den Rechen 5, der als Standardteil hergestellt werden kann und somit in verschiedenen Uhrwerken mit ersten, beispielsweise metallischen Rechen 4 unterschiedlicher Grösse, Teilung und/oder Module zusammenarbeiten kann.The pitch of the
Durch den erfindungsgemässen Mechanismus werden ein Spiel und Schwingungen beim Wechseln der Position des Anzeigers vermieden. Dieser steht somit an einer festen Position, auch wenn die Uhr durch den Benutzer bewegt wird.By the inventive mechanism, a game and vibrations when changing the position of the indicator can be avoided. This is thus at a fixed position, even if the clock is moved by the user.
