Definitions

  • the present invention relates to a set of head-to-tail flexible guides for a clock movement, in particular for a display device.
  • the invention also relates to a clock movement provided with such a set of flexible guides.
  • Fans of horological complications are sensitive to a certain animation of the displays of a timepiece, which can be provided by retrograde display mechanisms, or even tourbillon mechanisms or the like, which moreover guarantee better insensitivity to positions .
  • a retrograde mechanism is said to be a horological display mechanism which, having reached an extreme position, goes back and returns to its starting point.
  • retrograde date display mechanisms an example of which is given by a display hand which moves opposite an index on which appear the date indications from “1” to “31”. The display hand points successively to each of the date indications “1” to “31” then, when, at the end of the month, it reaches date indication “31”, it is pulled back and brought back next to date indication “1”. Then, the display hand starts to move next to the date indications from “1” to “31”.
  • Flexible guides also make it possible to design architectures of innovative mechanisms in display devices.
