Description

TECHNICAL AREA

The present invention relates generally to a timepiece, as well as to another time indicator device.

TECHNOLOGICAL BACKGROUND

[0002] Timepieces and other time indicator devices making it possible in particular to count the time are known from the state of the art. These known solutions are typically based on the use of a timer which is triggered selectively and manually by the user, where appropriate with the possibility of defining the start time of the timer.

[0003] Timepieces provided with "inverted" dials are known as such from the state of the art. These are parts specifically designed for left-handers in which the movement is configured to drive the hour and minute hands in an anti-clockwise direction, unlike the usual clockwise direction, and in which the digital hourly indications ( in Arabic or Roman numerals) carried by the dial are also distributed in the opposite direction to the usual meaning. Examples of such timepieces have in particular been marketed under the Juvenia brand, in the “Contresens” range, under the Louis Pion brand, under the Beuchat brand, in the “Revolve” range, as well as under the Franck Muller brand, in the “Contretemps” range. These are in fact timepieces requiring a movement configured to drive the time indicator member (s) in a direction opposite to the usual meaning, and which do not allow time to be counted down in the manner of a timer.

[0004] There remains a need to provide a timepiece or other time indicating device which provides an alternative indication of the time passing.

DISCLOSURE OF THE INVENTION

[0005] A general aim of the present invention is to provide a solution offering another perspective on the time which elapses, and more particularly on the time which remains in an hourly cycle of twelve or twenty-four hours.

More specifically, an aim of the present invention is to provide a solution which presents, in a particularly simple manner, an indication of the time remaining available before the conclusion of said hourly cycle.

Yet another object of the present invention is to provide such a solution which is not too complex to achieve compared to known solutions and requires only few modifications.

The present invention meets these aims by proposing, according to a first aspect of the invention, a timepiece whose characteristics are listed in claim 1, namely a timepiece comprising a movement arranged to drive at least a first time indicator member rotating about an axis, said first time indicator member being driven by the movement in a predetermined direction of rotation in order to perform one complete revolution in a clock cycle of twelve or twenty-four hours. According to this first aspect of the invention, the timepiece is provided with a series of digital time indications relating to said time cycle, which series of digital time indications is arranged and distributed around the axis of said first indicator member. time so that the first time indicator unit provides an indication of the time remaining available before the conclusion of said time cycle.

[0009] According to a first variant embodiment of the invention, the first time indicator member is a hand or another time indicator member comparable to a hand driven in rotation opposite a dial bearing said series of indications digital time, said series of digital time indications being arranged in increasing order and distributed around the axis of the first time indicator member in a direction opposite to the direction of rotation of said first time indicator member.

According to a second variant embodiment of the invention, the first time indicator member is a disc or a crown bearing said series of digital time indications and driven in rotation opposite at least one index or marking fixed, said series of digital time indications being arranged in increasing order and distributed around the axis of the first time indicator member in a direction identical to the direction of rotation of said first time indicator member.

Preferably, the timepiece further comprises a second time indicator member rotated by the movement around the axis at the rate of one complete revolution per hour. More specifically, in the context of the first variant embodiment mentioned above, the timepiece can advantageously comprise a second hand or another time indicator member comparable to a second hand driven in rotation by the movement around the axis. , opposite said dial, at the rate of one complete revolution per hour. Alternatively, in the context of the second variant embodiment mentioned above, the timepiece can advantageously comprise a second disc or a second crown driven in rotation by the movement around the axis, opposite said fixed index or marking. , at the rate of one complete revolution per hour, which second disc or which second crown carries a series of additional digital time indications relating to a one hour cycle, which series of additional digital time indications being arranged in ascending order and distributed around the axis in a direction identical to the direction of rotation of said first clockwise indicator member. In this case, the first time indicator member is driven discontinuously so that it jumps every hour from one position to the next.

In the context of an application to a twelve hour hourly cycle, the series of digital hourly indications preferably comprises at least the three digital indications three, six and nine hours, in Arabic or Roman numerals.

Still, in the context of an application to a twelve hour hourly cycle, the series of digital hourly indications may alternatively comprise an increasing series of twelve digital indications from 0 to 11.

The first time indicator member (as well as the second time indicator member, if present) can be used to indicate the usual time. Alternatively, the timepiece may include a complementary display mechanism for the usual time.

The timepiece according to the invention can take any suitable form, in particular the form of a wristwatch, a pocket watch, a table clock or a wall clock.

The present invention also meets the aforementioned aims by proposing, according to another aspect of the invention, a time indicating device whose characteristics are listed in independent claim 9, namely a time indicating device comprising a first means indicator of the usual time according to an hourly cycle of twelve or twenty-four hours and a second indicator means designed to count the time, the first and second indicator means being driven by a movement. According to this other aspect of the invention, the second indicator means is synchronized with the first indicator means so as to provide an indication of the time remaining available before the conclusion of said hour cycle.

This time indicator device can take the form of a timepiece equipped with said first and second indicator means (in particular a timepiece according to the first aspect of the invention). A programmed or programmable electronic device (in particular a portable electronic device such as a smartphone or a connected watch) could also fulfill the functions of said first and second indicator means.

Embodiments of the invention are explained in the remainder of the present description.

BRIEF DESCRIPTION OF THE DRAWINGS

The characteristics and advantages of the present invention will emerge more clearly on reading the following detailed description of embodiments of the invention, which are presented only by way of non-limiting examples and are illustrated by the accompanying drawings. or: FIG. 1 shows a partial schematic view of a timepiece according to a first embodiment of the invention; FIG. 2 shows a partial schematic view of a timepiece according to another embodiment of the invention; and FIG. 3 shows a partial schematic view of a timepiece according to yet another embodiment of the invention.

MODES FOR CARRYING OUT THE INVENTION

The present invention will be described with reference to various preferred embodiments as illustrated in particular by Figures 1 to 3.

Figure 1 shows a partial schematic view of a timepiece, generally designated by the reference 1, according to a first embodiment of the invention. This timepiece 1 can take any suitable form, in particular the form of a wristwatch, a pocket watch, a table clock or a wall clock, and is conventionally equipped with a movement. watchmaker (not shown) which can equally well be a mechanical movement with manual or automatic winding, or an electromechanical movement comprising one or more micromotors driving the cogs of the movement. In the example illustrated in Figure 1, the movement drives, in a conventional manner, a pair of hands in rotation about a common axis O, namely a first hand, or hour hands, 2h here operating a complete revolution in a twelve-hour hourly cycle and a second hand, or minute hands, 2m operating one complete revolution in a one-hour cycle. These hands 2h, 2m are rotated in a direction of rotation R corresponding to the usual clockwise direction. The hands 2h, 2m are driven in rotation around the axis O opposite a dial 5 carrying an increasing series of digital time indications 3a to 3d. In the example illustrated, this increasing series of digital time indications comprises a first digital time indication 3a indicating zero, i.e. the end of the time cycle considered, a second digital time indication 3b indicating three hours, a third digital time indication 3c indicating six. hours, and a fourth 3d digital time indication indicating nine o'clock, in Arabic numerals. Unlike a usual timepiece, this increasing series of digital time indications 3a-3d is not distributed around the axis O in a clockwise direction, but in an anti-clockwise direction, namely in an opposite direction. in the direction of rotation R of the 2h, 2m hands. It will also be noted that the dial 5 carries a complementary series of hour markers 4, distributed at regular intervals, marking the twelve hours of the considered time cycle. It is obviously understood that other arrangements can be envisaged, for example an arrangement comprising a series of twelve digital time indications distributed at regular intervals, in an anti-clockwise direction, around the axis O of the 2h, 2m hands. One or the other of the digital time indications could moreover possibly be omitted in order, for example, to make room for a window indicating the date or any other useful information.

It will be noted that the dial 5represented in FIG. 1 is similar to the “inverted” dials of the left-handed timepieces mentioned in the preamble. Unlike these left-handed timepieces, however, the 2h, 2m time indicating members are not driven in an anti-clockwise direction, but always in a clockwise direction, as in a conventional timepiece.

Leaving aside the digital time indications 3a-3d carried by the dial 5, it can be seen that the hands 2h, 2m jointly indicate ten hours and ten minutes (morning or evening). Together with the digital time indications 3a-3d carried by the dial 5, it can be seen that the 2h, 2m hands indicate one hour and fifty minutes, namely the time remaining available before the conclusion of the twelve hour cycle in question, that is to say 1:50 before noon or midnight. It is therefore possible to read the usual time, as well as the time remaining available before the end of the time cycle in question.

Figure 2 shows a partial schematic view of a timepiece, generally designated by the reference 1 *, according to another embodiment of the invention. This 1 * timepiece can likewise take any suitable form, in particular the form of a wristwatch, a pocket watch, a table clock or a wall clock, and is conventionally equipped of a watch movement (not shown). In the example illustrated in Figure 2, and in the image of the first embodiment, the movement drives a pair of hands in rotation about a common axis O, namely a first hand, or hour hands, 2h * operating a complete revolution in a twelve-hour hour cycle and a second hand, or minute hands, 2m * operating a complete revolution in a one-hour cycle. According to this other embodiment, and unlike the first embodiment, the hands 2h *, 2m * are however driven in rotation in a direction of rotation R * corresponding to the anti-clockwise direction. The 2h *, 2m * hands are rotated around the axis O opposite a dial 5 * bearing an increasing series of digital time indications 3a * to 3c *. In the example illustrated, this increasing series of digital time indications comprises a first digital time indication 3a * indicating three hours, a second digital time indication 3b * indicating six hours, and a third digital time indication 3c * indicating nine hours, in Roman numerals. This increasing series of digital time indications 3a * -3c * is distributed around the axis O in a clockwise direction, namely in a direction opposite to the direction of rotation R * of the 2h *, 2m * hands. Like the first embodiment, it will also be noted that the dial 5 * carries a complementary series of hour indices 4 *, distributed at regular intervals, marking the twelve hours of the considered time cycle. It is obviously again understood that other arrangements can be envisaged, for example an arrangement comprising a series of twelve digital time indications distributed at regular intervals, here clockwise, around the axis O of the 2h * hands, 2m *. One or the other of the digital time indications could likewise possibly be omitted in order, for example, to make room for a window indicating the date or any other useful information.

It will be noted that the dial 5 * shown in Figure 2est similar to the usual dials of conventional timepieces. Unlike these conventional timepieces, however, the 2h *, 2m * time indicating members are not driven in a clockwise direction, but in an anti-clockwise direction.

In the illustration of Figure 2, it is again assumed that the current time is ten hours and ten minutes (morning or evening). Together with the digital time indications 3a * -3c * carried by the dial 5 *, we can therefore see that the 2h *, 2m * hands, turning in an anti-clockwise direction, indicate one hour and fifty minutes, namely the time remaining available before the conclusion of the twelve-hour cycle in question, that is to say 1:50 a.m. before noon or midnight.

Even if the current time is readable by means of the timepiece 1 * of Figure 2, in the manner of the left-handed timepieces mentioned in the preamble, this reading "reversed" from the normal requires some practice and it will therefore be understood that this embodiment is mainly intended to provide an indication of the time remaining available before the conclusion of the time cycle concerned.

[0028] Figure 3shows a partial schematic view of a timepiece, generally designated by the reference 1 ', according to yet another embodiment of the invention. Like the timepieces 1 and 1 * previously described, this timepiece 1 'can take any suitable form, in particular the form of a wristwatch, a pocket watch, a clock. table or wall clock, and is conventionally equipped with a watch movement (not shown). The configuration of this other timepiece 1 ′ differs significantly from the embodiments described above. As regards the display of the time remaining available before the conclusion of the time cycle in question, it should be noted that the time cycle in question is always a twelve hour time cycle. The alternative of adopting a twenty-four-hour hourly cycle remains, however, perfectly conceivable. Unlike the previous embodiments, the display of the remaining time is no longer operated by means of a pair of hands, as in the embodiments previously described, but by means of two rotating discs or rotating rings, designated by the references 2h 'and 2m', which indicating devices 2h ', 2m' each carry a series of corresponding digital time indications 3h ', resp. 3m '. In addition, the timepiece 1 ′ is equipped with a usual time display mechanism, here arranged coaxially and in the center of the discs / crowns 2h ′, 2m ′. This usual time display mechanism here conventionally comprises a pair of hands, namely an hour hand 7h 'and a minute hand 7m', which hands 7h ', 7m' are rotated around a common axis of rotation O, clockwise, facing a dial 8 'bearing a series of twelve hour markers marking twelve hours. It will therefore be understood that the usual time display mechanism 7h '/ 7m' / 8 'allows the current time to be displayed on a twelve hour cycle, the hands 7h', 7m 'here indicating ten hours and ten minutes (morning or evening). This usual time display mechanism could be produced in any other suitable manner, and the example illustrated cannot limit the scope of the invention as claimed.

In the example illustrated in Figure 3, the movement drives the pair of discs / hourly crowns 2h ', 2m' in rotation about the axis O in a direction of rotation R ', here clockwise, to the image of the direction of rotation of the 7h ', 7m' hands. The first time indicator member 2h 'operates a complete revolution in a twelve hour hourly cycle, while the second time indicator member 2m' operates a complete revolution in one hour. According to this other embodiment, the first time indicator member 2h 'carries an increasing series of digital time indications 3h', which are distributed at regular intervals on the face of the first time indicator member 2h 'in the clockwise direction, namely according to a direction identical to the direction of rotation R 'of the clockwise indicator member 2h'. In the example shown, this is an increasing series of twelve digital indications, from "0" to "11". If the alternative of a twenty-four hour cycle were to be adopted, it will then be understood that the first 2h 'time indicator member would operate a complete revolution in twenty-four hours and would preferably carry an increasing series of twenty-four indications. digital, from "0" to "23". Moreover, the first time indicator member 2h 'is here operated discontinuously, in the manner of a date disc, that is to say it jumps, every hour, from one position to another. the next one. The second time indicator member 2m 'carries an increasing series of additional digital time indications 3m', which are distributed at regular intervals on the face of the second time indicator member 2m 'in the clockwise direction. More specifically, this is an increasing series of twelve digital indications covering a cycle of sixty minutes, from "0" to "55", with intervals of five minutes. Unlike the first time indicator unit 2h ′, the second time indicator unit 2m ′ is here operated continuously or almost continuously in order to duly register the passing minutes.

The reading of the time remaining available before the conclusion of the considered time cycle (here of twelve hours) is carried out thanks to at least one fixed index 6 'and / or 6 "(or any other marking), arranged here at "six o'clock", facing the two discs / crowns 2h ', 2m'. The fixed index or marking 6 'is here arranged so as to be partially superimposed on the indicator member 2h'. This fixed index or marking 6 'could for example consist of an element placed in a cantilever position, at six o'clock, above the indicator member 2 o'clock' or of a marking affixed to a glass of the timepiece. 'index or fixed registration 6 "is for its part arranged on the dial 8', as illustrated. One could also conceive of the index or fixed registration in the form of a window 5 ′ mainly leaving a glimpse of the concerned portion of the discs / crowns 2 h ′, 2 m ′ where the reading of the time remaining available is carried out, as illustrated schematically. in dashed lines in Figure 3. In this case, the indexes 6 ', 6 "would no longer have any particular utility and could be omitted. It will be understood, moreover, that the first and second time indicator members 2h', 2m 'are not necessarily visible in their entirety, but can be partially hidden if necessary. Thus, the 8' dial could be designed to extend radially and cover the 2h ', 2m' time indicators, in which case the 5 'window will then be made through the dial 8 '. The shape of this window 5' could be wider than that illustrated or be adapted in any other suitable manner in order to ensure optimal reading of the digital time indications carried by the hourly indicator (s) 2h ', 2m'. It is of course understood that the index or fixed registration can be placed at any suitable place, and does not necessarily have to be located at "six o'clock" as shown for purely illustrative purposes in Figure 3.

Anyway, it will be understood that, in the example illustrated, each disc / crown 2h ', 2m' is driven in rotation in the clockwise direction (direction of rotation R 'in the Figure 3) so that the fixed index or register 6 ', 6 ", resp. 5' gives a decreasing indication of the time remaining available until the conclusion of the twelve hour time cycle in question. In the example illustrated, the first and second time indicator members 2h ′, 2m ′ jointly indicate that the time remaining available before the conclusion of the considered time cycle is 1h50.

As an alternative, it is perfectly conceivable that the discs / crowns 2h ', 2m' are driven in an anti-clockwise direction, in which case the order of the series of digital time indications 3h 'and 3m' should be reversed.

The timepieces presented with reference to Figures 1 and 3 constitute exemplary embodiments of a time indicating device comprising a first means indicating the usual time according to a twelve hour hour cycle (or alternatively twenty-four hours) and a second indicating means adapted to count down the time, which is synchronized with the first indicating means so as to provide an indication of the time remaining available before the conclusion of the hourly cycle.

In the embodiment of Figure 1, the indicator members 2h, 2m indeed provide, together with the hour markers 4ported by the dial 5, an indication of the usual time (namely 10:10 in the illustrated configuration) , thus fulfilling the function of the first means indicating the usual time. The indicators 2h, 2m also provide, together with the digital time indications 3a-3d carried by the dial 5, an indication of the time remaining available before the conclusion of the time cycle concerned (namely 1h50 in the illustrated configuration).

In the embodiment of Figure 3, the usual time is indicated by a complementary display mechanism 7h ', 7m', 8 ', which therefore fulfills the function of the first indicator means of the usual time . The indicator members 2h ′, 2m ′ provide, together with the index or fixed register 5 ′, 6 ′, 6 ″, an indication of the time remaining available before the end of the time cycle concerned.

The functions of the first and second indicator means could be performed in any other suitable manner while ensuring synchronism between the usual time and the indication of the time remaining available before the conclusion of the time cycle. Thus, for example, the second indicating means could alternatively take the form of a timer automatically counting down twelve or twenty-four hours, which timer is automatically reset at the start of each hourly cycle.

In view of the above, it will therefore be understood that the presentation of an indication of the time remaining available is not specifically limited to a mechanical or electromechanical timepiece, but could also be carried out under the in the form of any other time indicating device, in particular in the form of an electronic device programmed or programmable in order to fulfill the functions of said first and second indicating means. By way of example, it could perfectly be implemented in the form of a smartphone on which a software application or a connected watch would be installed in order to fulfill the functions of said first and second indicator means.

It will generally be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiments described in the present description without departing from the scope of the invention defined by the appended claims.

For example, instead of the needles 2h, 2m, resp. 2h *, 2m *, it is possible to use any other time indicator member comparable to a hand, such as for example a transparent disc bearing an index, which transparent disc is driven in rotation above the dial 5, resp. 5 *, or an indicator member arranged so as to be driven in rotation on the periphery of the dial 5, resp. 5 *.

[0040] It is also perfectly conceivable to affix additional indexes or markings on the dial 5, resp, 5 *, or on the time indicator members 2h ', 2m', such as graduations allowing a finer reading of the remaining time. available.

Furthermore, the first aspect of the invention can be implemented by using a single time indicator member making a complete revolution in an hour cycle of twelve or twenty-four hours, or even more than two time indicator members. Thus, for example, the time indicator member 2m 'of Figure 3 could potentially be omitted, in which case it would then be appropriate for the drive of the time indicator member 2h' to be carried out continuously or almost continuously, rather than by jumps. Likewise, an additional time indicator unit could be provided in order to count down the seconds, for example. In this regard, this additional time indicator member could take any suitable form, in particular but not exclusively the form of a hand or of a disc or of a crown.

Finally, the positions of the first and second time indicator members illustrated in Figure 3 could be reversed so that the second time indicator member 2m 'is placed outside the first time indicator member 2h'.
