Stopping mechanism for timepiece striking mechanism

A stopping mechanism for a striking mechanism for a watch or timepiece comprising a movement, said striking mechanism and/or said movement comprising energy storage means arranged to power said striking mechanism to perform the striking functions, at an output of said energy storage means which comprise a power reserve transmission wheel set, said striking mechanism comprising at least one strike drive wheel set comprising a detent ratchet and a repeating rack pinion, a main click for the passing strike function and/or a click for releasing a minute repeater when said striking mechanism includes a minute repeater, wherein said stopping mechanism includes a strike uncoupling lever arranged to move away from said strike wheel set said main click and said minute repeater click when said striking mechanism includes a minute repeater, by an instantaneous jump of a repeating-slide control lever arranged to cause a change of position of said strike uncoupling lever, as soon as the level of available energy in said storage means crosses a predefined threshold, by the cooperation between, on the one hand, a stop finger indirectly driven by said power reserve transmission wheel set and, on the other hand, a stop jumper returned by a first spring, to bring a stop pin integral with said stop finger to bear on a fork comprised in said repeating-slide control lever, to cause an abrupt pivoting of said repeating-slide control lever by the instantaneous change of position of a lug comprised in said repeating-slide control lever with respect to a second spring.
