DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

In the following description, the same numerical references refer to similar components. Embodiments (geometries, dimensions, etc.) illustrated in the figures and features described in the application are preferred only, given for guidance only.

In addition, although the present invention is primarily designed for use with a "time indicator", such as a watch, a clock, a dial, or even an alarm clock for example, and intended (e) to receive a component and / or a complementary accessory, the invention can be used with any other type of object, and in other fields, as is obvious to a person skilled in the art. Therefore, expressions such as "time", "hour", "minute", "second", "watch", "clock", etc., as used herein, and / or any other reference and / or or any other expression equivalent or similar to the latter should not be considered as limiting the scope of the present invention and include any other object / substitute and / or any other possible application with which the present invention may be used and may be useful, as is obvious to a person skilled in the art. In particular, it should be recalled that although the present system was designed primarily for a watch mechanism, the present system is not limited to such purposes. In particular, as will be better understood from reading the present specification, the present mechanism is capable of providing a mechanical response for a two-variable function. Therefore, it can serve as a machine to add or multiply or divide or subtract two numbers from each other, using linear functions. Therefore, one realizes that when leaving the "watchmaking" application, the notion of periodicity is no longer fundamental because the answer sought is no longer based on the periodicity of an astronomical phenomenon.

In addition, although the preferred embodiments of the illustrated system have several components and characteristics, all these components are not necessarily essential to the invention and consequently must not be taken in their restrictive sense, that is to say should not be considered so as to limit the scope of the present invention. It should be understood, as is obvious to one of ordinary skill in the art, that other suitable components and geometries and / or other possible interactions between them can be used for the system according to the present invention, such as that they will be described below, without departing from the scope of the invention. In addition, in the context of the present invention, expressions such as "mechanism", "system", "device", "set", "mechanism", "product", "watch", "clock", "dial", "alarm clock", etc., as well as any other equivalent expression and / or compound words thereof, may be used interchangeably in the context of this description.This also applies to other expressions which are mutually equivalent, such as, for example: a) "time", "moment", "instant", "hour", "minute", "second", etc. b) "curve", "course", "trajectory""," behavior "," graphical representation "," sinusoidal "," sinusoidal variable ", etc. c)" drive "," transmission "," transformation "," correction "," adjustment "," modification "," alteration "," amplification "," reduction "," cancellation "," inversion ", etc. d)" needle "," indicator "," display "," slider "," shutter "," signal ", etc. e) "connecting rod", "connector", "rod", "arm", etc., as well as for other expressions being mutually equivalent, concerning the aforementioned expressions and / or any other structural and / or functional aspect of the present invention, as is obvious to a person skilled in the art.

Moreover, in the context of the present description, it should be considered that all elongated objects implicitly have a "longitudinal axis" and / or a "center line", such as the longitudinal axis of a stem, for example, or the center line of a spiral spring, and expressions such as "connected" and "fit to be connected", or "pivotable" and "rotatable", may be interchanged and are mutually equivalent, in that the present invention also relates to a kit with corresponding components for assembling a fully assembled and operative resultant mechanism, including a clockwork mechanism and / or other related provided with such a mechanism. In addition, certain components of the present system and / or steps of the present method being described in this specification may be modified, simplified, omitted and / or interchanged, without departing from the scope of the present invention, depending on the particular applications for which the present system is designed and / or intended, and also depending on the desired results, as briefly described herein and as also evident to a person skilled in the art.

In general, the present invention, as illustrated in the accompanying figures, relates to a mechanism capable of displaying regular recursive nature information (eg, periodic, etc.), such as the times of sunrise. and / or sunset, as well as the hours of the first glow, as well as the last apparent glow in the sky, etc., according to first and second adjustment systems representative of the latitude and the date of use of the mechanism.

The main advantage of the present system over existing ones is its ability to be functional and adjustable for latitudes between 60 degrees north and 60 degrees south, for example, although other latitude ranges are contemplated for present mechanism. Moreover, this system allows to display the hours of Islamic prayers.

Other aspects, objectives, embodiments, possible variations and / or resulting advantages, of various components and possible features of the present invention, all of which are preferred and / or optional, are briefly described below.

(content of the claims to be inserted here, with reference to the figures concerned, if applicable - to be done in a timely manner, for example, following a filing of Chapter II of the PCT procedure) As previously explained, in general terms, the present invention relates to a mechanism capable of displaying information of the recurring nature on a regular basis (eg periodically, etc.), such as the times of sunrise and / or sunset, as well as the hours of the first glow, as well as the last glow apparent in the sky, etc., according to first and second adjustment systems representative of the latitude and date of use of the mechanism. The main advantage of the present system over existing ones is its ability to be functional and adjustable for latitudes between 60 degrees north and 60 degrees south, for example, although other latitude ranges are contemplated for present mechanism. Moreover, this system allows to display the hours of Islamic prayers.

Referring to Figures 1 to 14, and more particularly to Figures 2 and 4, this is characterized by a timing display corresponding to:

1. the appearance of a white glow on the horizon (see component 127a);

2. the appearance of the solar disk (see component 125a);

3. the position of the sun at the zenith (see component 127d);

4. the length of the shadow of an object identical to its height plus the length of its shadow at the zenith (see component 127c), named "Asr";

5. disappearance of the solar disk (see component 125b);

6. the disappearance of the reddish glow in the sky (see component 127b).

The position of each of these moments in a day is dependent on the position of the earth on its orbit (ie "the date") as well as the position of the place where one wishes to obtain this information (ie "the latitude") . Another display system follows the rotation of the earth, indicating the hours (component 127e), to indicate the presence of the moment when the information is superimposed.

The present mechanism thus allows the adjustment of the following three parameters:

at the date;

(b) latitude; and

c) time.

Regarding the operation:

According to a possible embodiment, the mechanism is decomposable into three large sets:

a) the main system synchronized with date and latitude;

(b) the system of transmission and transformation of movements; and (c) the information display system.

Concerning the main system:

The main system is adjusted to the chosen date. It can be automated, for example by rotating every year. Various elements are integrated in order to be in solidarity with this rotation:

1. the system of adjustment of the latitude;

2. the system of correcting the equation of time; and

3. the system for correcting the position of the hands. Concerning the system of adjustment of the latitude:

In order to adjust the latitude, an axis is moved from the center of the main system disk corresponding to the equator to the periphery of the disk for the largest latitude processed. The change of hemisphere is done by a 180 degree rotation of the disc, which is why the date is preferably indicated by a "north" indication and a "south" indication diametrically opposed to the latter, although other ways of doing things are possible. In particular, the axis can also be moved from one side to the other of the center of the disc of the main system, where one side corresponds to the southern hemisphere, the other side opposite by the center of the disc corresponds to the north. It should be noted that in the present embodiment given by way of example, the date indication disk is fixed to the bridge, and its rotation is therefore integral with that of the main disk.

A toothed ring on its inner and outer spokes is superimposed on the main system and driven with the latter. In order to adjust the latitude, the user rotates this ring with respect to the main system. This differential rotation drives a wheel provided with a pinion mounted on the main system. The pinion drives a wheel which is provided with an arm at the end of which is fixed a connecting rod mounted on pivot at each end, this rod causes the axis to move to its position corresponding to the chosen latitude.

At the top of the wheel with pinion is fixed a needle to display the corresponding latitude on the bridge that keeps the ring to the main disk with the support on which is engraved the mark. This bridge is graduated and also acts as a dial. Concerning the system of correction of the equation of time:

In order to correct the effects of the equation of time, on the main disk is traced in relief or in relief a line describing a complete turn and allowing to move a connecting rod presses on the outline whether in relief or provided with a finger taken in the tracing if in hollow. The movement of this rod is transmitted to the support of the hours display dial by a rod to correct its position. The dial, crown on which are displayed the hours turns freely on its support in order to allow the user to coordinate the solar indications of the needles to the administrative time.

Regarding the system for correcting the position of the hands:

The correction of the position of the hands is done according to the same principle as the system described in the previous section concerning the system of correction of the equation of time, the difference is that the movement of the connecting rod following the trace is transmitted to the slide described in the next section concerning the "C" set (see below). This movable slide can be substantially straight, and / or slightly curved, as needed.

Concerning the movable slides:

Under the main system a set of movable slides are superimposed and are taken in a guide to limit their movement (s) along a single axis of translation. The shape of each slide can be different in order to modify the kinematics of its translation. The main system axis passes through each slider to link the main system to the sliders. It should be noted that this axis is not necessarily rectilinear but may be in the form of a crank to change the amplitude of each slide. Each slide has a rack to transmit its translatory movement to a wheel.

Several changes and / or alternative embodiments can be made to the present examples of operation having been given. For example, the rack wheel pair can be replaced by a connecting rod connecting the movable slide to a wheel or a crank.

Regarding variable spoke wheels:

Each gear driven by the corresponding slide has a half whose radius is constant and another half whose radius is variable. The variable-radius portion drives another variable-radius wheel, thus making it possible to modify the rotation from one wheel to the other depending on the amplitude reached.

Again, several changes and / or alternative embodiments can be made to the present examples of operation having been given. For example, the variable spoke wheels can be replaced by return systems such as those described in Figure 11. The translational movement of the slide is transformed into a rotational movement of the piece provided with a slide acting as a lever arm radius (s) Variable (s) whose axis of rotation is ticked by a needle. The junction between the workpiece and the lever arm to variable effective length is via a connecting rod. The connecting rod and the lever arm with variable effective length are joined by a pin. The pin and taken in a guide thus making it possible to vary the distance between the pin and the axis of rotation of the part. Regarding referrals:

Variable spoke wheels have a lever. A connecting rod is attached on one side to this lever and the other comprises an axis which is taken in a slide limiting its movement to a translatory movement in the direction of the corresponding slide.

Concerning the set "A": The set "A" allows the indication of the appearance and the disappearance of the solar disk as well as the representation of the duration of the night by the contrarotative movement of the shutters. In order to cause a counter-rotating movement, the axis provided with a lever is connected to the axis by means of a connecting rod. The shutters are linked to their corresponding axis (s).

Concerning the set "B":

The set "B" allows the indication of the appearance of the first glow of the sun in the morning and the disappearance of the red glow of the sun at the end of the day by the contrarotating movement of the needles. The axis moves in the slide then driving the lever via the connecting rod. The curve of the slide makes it possible to modify the amplitude during the rotation of the axis. The rotation of the axis causes the displacement of the axis via the connecting rod. The displacement of the axis causes the rotation of the axis which is provided with a lever connected to the axis via the connecting rod. The needles are attached to their respective axis (s).

Concerning the set "C":

The set "C" allows the indication of the prayer named "Asr" taking place during the afternoon. The rotation of the wheel causes the displacement of the axis in the slide via the connecting rod. As previously explained, this slide can be substantially straight, and / or slightly curved, as needed. The displacement of the axis causes the rotation of the axis via the connecting rod. The indication needle of "Asr" is attached to the axis. The position correction of this needle is performed by the movement of the slide in its guide: this movement is translatory and if necessary also rotatable. The movement of the slide is due to the movement of the connecting rod which is transmitted through the shaft. The movement of the connecting rod is described in the previous section concerning the needle position correction system.

Regarding the display:

The display system has a bottom and three similar flaps, two of which are movable. The bottom symbolizes the day while the surface occupied by the three shutters symbolizes the night. The needle (III) is fixed and symbolizes the moment when the sun reaches its zenith. The operation of the other needles is described in the previous sections.

It should be noted that in another version, the three flaps and the bottom can be replaced by two disks cut on one of their spokes. The two disks are nested in their respective cutouts and centered so that one partially overlaps the other. One disc represents the night and the other the day, they each turn in an opposite direction to vary the representation of the duration of the day and the night. Each cut corresponds to the representation of the sunrise (eg a cut corresponds to the sunrise, while the other corresponds to its setting). In addition, the bottom can also support a representation of the night on one half of its surface and the day on the other. In the center of the day part can be represented the sun. The bottom then rotates once a day so that the sun shown is synchronized with the actual sun for the sunrise (s) and sunset (s) of the sun (ex. to appear and / or disappear at the same time as the lift (s) and / or bed (s) of the latter, etc.).

The needle rotates by 24 hours and the graduated dial allows the reading of the time, the position of this dial is manually adjustable; it is further corrected in time by the movement of the ring to compensate for the effects of the equation of time.

Several changes and / or alternative embodiments can be made to the present examples of operation that have been given, and in support of this, equivalent and / or related versions of mechanism (s) different from those described in FIG. 1 to 14 are now given by way of example (s), with reference to FIGS. 15 to 28. With regard to the description of the system:

The system shown in Figure 16 is intended to reproduce sinusoidal movements whose amplitude is adjustable and invertible. It allows, according to a different method, to perform the same functions as the mechanism having been described above (with reference to Figures 1 -15), hereinafter the "previous version".

Concerning the positive points (and / or "advantages"): The main interest of this version lies in its simplicity. It has a number of parts much lower than the previous version, its size is minimized. Also the energy losses by friction are significantly reduced. The cam principle allows greater freedom and simplification of the system for complex displays thanks to the freedoms permitted as to the design of his profile. Also, the present mechanism has all the advantages of the previous version.

Regarding the points to watch:

One of the points of this system to be monitored is that for a complete inversion of the amplitude (see Figure 19), the arm requires an "infinite" length so that the movements of the follower and the pusher are equal. Also, the ratio between the display amplitude and the position of the pivot is not identical depending on whether the pivot is in the positive or negative zone.

Concerning the principles of operation (eg system kinematics, system tuning, etc.): Concerning the kinematics of the system:

Preferably / optional, the cam rotates at the speed of one revolution per year thus causing the translation of the follower whose degrees of freedom are limited to a single axis in translation by the rail. The follower is held in support on the cam by the force of the spring. The arm rotates around the pivot, it is driven by the translation of the follower to which it is held by means of the screw. The rotation of the arm causes the translational movement of the pusher held in its rail. The movement of the pusher causes the rotation of the rudder on which is mounted the needle which displays the information for which the mechanism was designed. This is an application Thales theorem.

Regarding the system setting:

Preferentially / optionally also, the adjustment of the amplitude, corresponding here to the latitude, is done by moving the pivot maintained in its slide. As shown in Figure 20, the pivot position varies the position of the needle. Figure 18 illustrates that when the pivot is aligned with the axis corresponding to the screw the deflection of the needle is zero; this position corresponds here to the equator. Comparing Figure 17 with Figure 19, we see that the position of the needle is reversed depending on whether the pivot is on either side of the pusher, this illustrates a setting for north latitude and latitude South. The needle therefore indicates the amplitude chosen during the adjustment, here the latitude. Note that the slide is represented here "right", but it can however take curved shapes to create a shift of the points of inflection of the curves according to the latitude. This shift is particularly important for curves such as those shown in area 1 of Figure 24.

For alternative systems (eg spring, cam, screws, displays, amplitude adjustment, amplitude display, etc.): a) for the spring: the spring can be replaced by a torsion spring mounted on the pivot or the axes created by the screws;

b) concerning the cam: the cam can be replaced by a crank linked to the follower (2) via a connecting rod;

c) concerning the screws: the screws can be replaced by any means to create a connection between the elements here held together with a degree of freedom in rotation about the axis of the screws shown in Figure 15. These means can in particular be systems of pins, ball joints, connection via an elastic part allowing angular flexion, etc .; and

d) regarding the displays: the spreader and its hand are shown here for illustration. There are a large number of possible combinations for exploit the output kinematics of the pusher. The display may especially take the form of a slider driven by the pusher, a shutter shutter in translation or rotation. Figures 21, 22 and 23 illustrate different ways to exploit the kinematics of the pusher.

The transmission rod shown in Figures 22 and 23, has the advantage of truncating the curves, as shown in area 2 of Figure 24, and correct the display at high magnitudes without influencing the position of the display at lower amplitudes. To do this, the rod is on one side connected to the arm by a pivot, here the screw, and on the other to the rudder by another pivot, here the screw. The pivot connecting the connecting rod to the rudder passes in a guide which is here represented right. It is by drawing the curved shape guide that we obtain the necessary corrections to truncate curves, as illustrated in area 2 of Figure 24. Among the means to arrive at the correction described the toothed wheel of the Figure 21 may be linked to a gear train having at least two non-circular gear wheels for transmitting the movement to the display as described in the "previous version".

Concerning the adjustment of the amplitude:

The assembly for moving the position of the pivot in the guide may be composed of a crank and a connecting rod. It is a solution among several other alternatives to meet the same function. Among these alternatives, we can notably mention a displacement of the pivot by endless screw or by rack.

Regarding the amplitude display:

By way of illustration the needle is here secured to the crank via the axis. The latitude can be indicated on a ring gear to inside or outside the latter driving the crank via a pinion or a gear train). For the same purpose, this crown can also cause a needle mounted on a toothed wheel. In order to obtain a linear display of the latitude, the crank may be engaged by a non-circular toothed wheel; in this case the display of the latitude, here the needle, will be mounted on this gear.

Figure 24 illustrates the type of needle movements or sliders that the mechanism allows depending on the days of the year (position of the rod in rotation) and the latitude (position of the pivot). The curve having the minimum amplitude corresponds to the equator, the curve having the maximum amplitude corresponds to a latitude of 60 degrees north. The corresponding curves at the southern latitudes are the same as those shown in Figure 24 but with a half-year lag.

Regarding the transmission variant of the previous version:

Figures 25, 26 and 27 illustrate a variant of the transmission system as previously explained.

Several other changes and / or alternative embodiments can be made to the present examples of operation that have been given, and in support of this, equivalent and / or related versions of mechanism (s) different from those described. with reference to Figures 1 to 28 are now given by way of example (s), with reference to Figures 29 to 40.

Indeed, the present watch mechanism has the function of ensuring the amplification, reduction, inversion and / or cancellation of a mechanical input signal. This mechanism is particularly effective for the treatment of Circular or translatory periodic movements whose amplitude is to be varied according to two parameters.

The present mechanism can be divided into four main sets which are the input signal, the variation of its amplitude, its correction and its display.

Regarding the display In the case illustrated, the system displays the duration of day and night and the sunrise and sunset times according to date and latitude. The duration of the night is represented by the area occupied by the shutters, the duration of the day is represented by the surface not covered by the three components mentioned above. The moments of sunrise and sunset are represented by the border between the shutters and the disk. This disc performs a complete rotation in 24 hours. On this disc a landmark, which here is a representation of the sun, allows to visualize the progress of the day from sunrise to sunset. The setting of this disc is made so that sunrises and sunsets occur at the same time on the mechanism and in reality. If necessary, a fixed dial can be added at the periphery of the disc of this system, this dial takes the form of a ring divided in 24 hours throughout its turn. The adjustment of this dial on the time of sunrise or sunset thus makes it possible to read the time indicated by the representation of the sun or any other slider provided for this purpose on the disc.

The length of the day or times of sunrise and sunset are dependent on date and latitude. The adjustment ring of the latitude is here actuated in rotation by the user, this element comprises an indicator integrally attached to the ring. This indicator is superimposed with the chosen latitude or city that is inscribed on the latitude dial. The adjustment ring of the latitude can be operated manually by an outer ring and / or any other mechanical or electromechanical means, manual or automatic.

The date dial performs one turn per year. The date is read directly opposite the indication provided for this purpose on the dial, here between the north and south inscription. If necessary, the user can adjust the position of the date dial. This dial dates can be driven by any means manual or mechanical. The disc performs one turn in 24 hours. Part of it represents the night, another part represents the day and the sun. So that the representation of the night is majority on the dial during the real night and that the representation of the day on the dial is majority during the real days. Also on the disc, can be written technical indications as landmarks ahead of the representation of the sun and thus to know a duration before sunset. This mark can be fixed and correspond for example to the average duration that requires a course of 9 and / or 18 holes in golf, allowing the user to know if it is possible to play a full game before the fall of the night. In the same way, an indication or graduation integral with the disk or adjustable in advance on the sunset time can be useful in fields such as aeronautics and / or boating and / or mountaineering for a remaining duration before sunset. A time scale on the disk can also be used to indicate the time remaining before sunrise by reading on the edge of the shutter corresponding to the sunrise.

It should be noted that here the disc rotates clockwise, the sunrise then corresponds to the shutter and its setting to the shutter. Regarding the input signal

Rotating the date adjustment ring allows you to vary the input signal of the system. The ring has a cam drawn on its inner radius. The amplitude follower is kept in contact with this cam by the amplitude spring. The input signal therefore corresponds to the angular displacement of the follower on the cam. The date dial is held solidly to the date adjustment ring so as to rotate with it. The indication of the dates could be done by any other means such as a display by guiche or by needle on an auxiliary dial.

Regarding the variation of the amplitude:

The variation of the amplitude is done by the rotation of the adjustment ring of the latitude in which is drawn a cam in its center. On this cam, the latitude follower is held in contact by the latitude spring. The rotation of the cam of the ring therefore causes an angular displacement of the follower, this displacement is transmitted to the latitude pivot via the connecting rod. The displacement of the latitude pivot is along a translation axis perpendicular to the axis of displacement of the amplitude rod. It is the position of the pivot of latitude which makes it possible to preserve all the amplitude of the input signal, to invert its amplitude or even to make it null; this corresponds to the choice of a terrestrial hemisphere then to the reversal of the signal to the change of hemisphere and the cancellation of the signal for the equator. The amplitude arm is attached to the follower so that it can be pivoted relative to each other. The amplitude rod is held on the arm so that it can pivot relative thereto. The rod can move only along a translation axis passing through the center of the system. The elements to be translated are guided, it may be possible to replace these guides by a rotation at the end of an arm, provided that this arm is long enough to consider that the element translate because the displacement along the second axis of translation is negligible. For example, the pivot could then be held directly on the part without the intermediary of the connecting rod. The displacement of the amplitude link corresponds to the output signal which has yet to be corrected.

Signal correction: Under the date adjustment ring is a ring gear on its inner radius which meshes with the gear wheel). The toothed wheel is mounted on a pinion which engages the toothed wheel which itself rotates the toothed wheel. On the toothed wheel is fixed the correction cam of the equation of time. This cam performs a complete turn when the date adjustment ring also performs a full turn. The follower hammer is held in contact on the connecting rod by means of a spring. The follower hammer is moved by the cam and guides the rudder which is fixed on the amplitude rod, so that it can only rotate under the action of the follower or translate with the displacement of the amplitude rod. On the rudder are mounted racks that cause the rotation of the gears. The racks are driven by the translational movement of the connecting rod which causes a counter-rotating rotation of the gears thereby causing the flaps to rotate so as to vary the duration of the day. The displacement of the follower causes the gears to rotate (in the same direction, thereby correcting the time equation phenomenon by compensating for the delay or advance of the disc.) The flap pivots under the direct action of the rotation. It should be noted that the toothed wheels are not exactly circular so as to correct the fact that the signal does not have exactly the same speed in large and small amplitudes. Regarding variants:

This same mechanism can in particular be dedicated to displaying the duration of the daily increase or decrease of days according to the date and the latitude.

In this text for any other system the term year can be replaced by period and the term latitude by parameter of the adjustment of the maximum amplitude.
