Description

Calendar module for a timepiece date movement

Technical Field

The present invention relates to date watches, and more particularly, to an adaptable module on a date mechanism.

Background

On the one hand, the development of timepiece movements requires a considerable amount of time, while on the other hand, the market and/or the customization of watches require very short response times.

Thus, the horological may not be able to meet the requirements when customizing the watch.

SUMMERY OF THE UTILITY MODEL

The present invention proposes to overcome all or part of the above drawbacks by means of a calendar module for a timepiece date movement (i.e. a timepiece movement with a date); the timepiece date movement optionally includes a date drive wheel; the calendar module optionally comprises:

-at least one date driving disc; said at least one date driving disk comprises at least one first tooth and/or at least one second tooth, said at least one first tooth being configured to cooperate with said date driving wheel at each date jump; and

-at least one date indicator; the at least one date indicator is configured to be driven by the at least one first tooth or the at least one second tooth such that the at least one date indicator for indicating at least one date of a set of dates indicates a new date of the set of dates at each date jump of the date mechanism.

Thanks to this arrangement, it is possible to modify an existing timepiece movement to adapt it to the new design.

According to one embodiment, said calendar module comprises at least one intermediate element arranged between said at least one date driving disc and said at least one date indicator; the at least one intermediate element is configured to be driven by the at least one second tooth and to engage with the at least one date indicator such that, at each date jump of the date mechanism, the at least one date indicator indicates a new date of the set of dates.

According to one embodiment, said at least one first tooth is located on the outside of said at least one date driving disc or on the inside of said at least one date driving disc.

According to one embodiment, said at least one second tooth is located inside said at least one date driving disc or outside said at least one date driving disc.

According to one embodiment, said at least one date driving disc is at least one date disc or at least one date wheel.

According to one embodiment, said at least one date indicator is at least one date indicator disc or at least one date indicator wheel.

Drawings

The invention will be described in more detail below using the attached drawings, given as non-limiting examples, wherein:

figure 1 shows a prior art timepiece movement;

figure 2 shows a calendar module 100 comprising at least one date driving disc 110 cooperating with a date driving wheel 210; and

figure 3 shows at least one intermediate element 120 driving at least one date indicator 130.

Detailed Description

Fig. 1 shows an example of a timepiece movement 200, which includes a date driving wheel 210. In the example of fig. 1, the date driving wheel 210 comprises a wheel with a catch, which rotates one revolution for 24 hours and thus drives a conventional date disc 201 to change the date. For example, in the example of fig. 1, the date may be displayed at the indicia "3" of the dial. Such date display position should be the same for all watches using the timepiece movement 200.

The calendar module 100 according to the present invention may overcome this drawback by replacing the conventional date disc 201 with at least one date driving disc 110, wherein the date driving disc 110 optionally takes the form of at least one date disc 110 as shown in fig. 2, or at least one date wheel 110.

These alternative embodiments of said at least one date driving disc 110 may comprise at least one first tooth 111, which is arranged on the outside or on the inside of said at least one date driving disc 110 and can cooperate with said date driving wheel 210 each time a date jumps.

One or more holes may be drilled in the timepiece movement 200 to optionally receive at least one date indicator 130 and/or at least one intermediate element 120.

Optionally, in some embodiments, said at least one intermediate element 120 can be in contact with said at least one date driving disc 110 by means of at least one second tooth 112.

Indeed, in some embodiments, said at least one date indicator 130 can be driven directly by said at least one date driving disk 110 through said at least one first tooth 111 or through said at least one second tooth 112.

In the embodiment of fig. 2, said at least one intermediate element 120 may be driven by said at least one second tooth 112 arranged inside or outside said at least one date driving disc 110, so that said at least one intermediate element 120 may transmit the movement of said at least one date driving disc 110 by in turn driving said at least one date indicator 130.

The at least one date indicator 130 can be in the form of at least one date indicator disk 130 or at least one date indicator wheel 130, wherein the numerals (not shown) of the date indicator disk 130 are visible through an aperture that can be formed in the dial, and wherein a pointer (not shown) is mounted on the date indicator wheel 130 and indicates one date of the set of dates.

Thus, at each date jump of date mechanism 210, the at least one date indicator 130 indicates a new date in the set of dates. The set of dates may be located in a different location than the date display, which may be at the indicia "3" of the dial. In the example of fig. 3, if the at least one date indicator 130 is at least one date indicator wheel 130, the set of dates may be located at the label "6" of the dial, and the individual dates in the set of dates, i.e., dates from "1" to "31", may be located in the dial region between the center of the timepiece movement 200 and the label "6" of the dial.

Obviously, the conventional date disc 201 can be used and the at least one first tooth 111 and the at least one second tooth 112 can be merged, so that the calendar module 100 can be composed to some extent of the at least one intermediate element 120 and/or the at least one date indicator 130. The date driving wheel 210 thus drives the conventional date disc 201, which makes it possible to indicate a new date of the set of dates, optionally by means of the at least one intermediate element 120, through the at least one date indicator 130.

Thanks to this arrangement, said calendar module 100 makes it possible to modify an existing timepiece movement and adapt it to a new design by positioning said set of dates all around the centre of the movement 200 and at different distances from the centre of the movement 200.
