Problems solved by technology

However, a scroll wheel display for a watch requires considerable bulk and is difficult to fit in a watch
Furthermore, in order to avoid interpretation confusion when the time or date changes, it is preferable to adopt a momentary jump display, which is more complicated
These limitations are further magnified when this second display refers to values ​​that have different units than the first display, requiring conversion mechanisms that further complicate the structure of the table

Embodiment Construction

[0063] One row corresponds to one minute.

[0064] Double or square brackets correspond to the opening of the scroll wheel.

[0065] The table in Figure 6 shows only the minute display of "00" to "30" as it can be noted that there is a ten minute period

[0066] It is noted that the inner roller 1B and outer roller 1A each rotate six times over a ten minute period.

[0068] Therefore, the minute display requires the minute cam 21 and the ten-minute cam 22.

[0069] Similarly, the hour table in Figure 7 includes seven columns:

[0070] One row corresponds to one hour.

[0071] The table in Figure 7 shows the display for the hours "00" to "24".

[0072] Note that columns 4 and 5 of the hour table have a twelve hour periodicity.

[0074] Column 6 shows that when a switch is made at midnight (the switch does not match the general frame), the scroll wheel must be

[0076] The reader is referred to these tables to understand some specific display variation configurations, which will be d...

Abstract

A roller skipping timepiece display mechanism (100), each display device comprising a roller (1, 1A, 1B, 2, 3, 3A, 3B, 4) and / or a combined roller (10), comprising two rollers (1A, 1B, 3A, 3B), one of said two rollers (1A, 1B, 3A, 3B) being located inside the other, each display device being held in a rest position by a first elastic return means (311, 312, 313, 314, 316), at least one display device being rotatably movable, the rotation is controlled by the movement of at least one lever (11, 12, 13, 14, 15, 16), the lowering of which is controlled or prohibited by at least one cam (21, 22, 23, 24, 244, 245, 246, 247) driven by the timepiece movement (500), and at least one trigger lever or correction lever is arranged in bearing cooperation with both cams simultaneously, second resilient return means (119, 129, 139, 149, 159, 169) return the at least one trigger or correction lever towards the two cams.

Description

Roller-jump timepiece display mechanism technical field [0001] The present invention relates to a scroll wheel jump type timepiece display mechanism. [0002] The present invention also relates to a timepiece, in particular a watch, comprising at least one movement arranged to drive a movement comprising The cam in the display mechanism of such a roller-jump timepiece. [0003] The present invention relates to the field of timepiece display mechanisms. Background technique [0004] It is often difficult to combine different displays on a timepiece, especially when the timepiece is of a small size like a watch Time. [0005] And importantly, it is easy to distinguish between primary and secondary displays without any risk of confusion. [0006] One solution is to use a conventional display device (such as a pointer or dial) for the first display, and use a scroll wheel for the display device as a second display. However, the scroll wheel display for the watch requires a ...
