Abstract
A timepiece with a striking mechanism having a detent ratchet cooperating with a passing strike actuation click controlled by a movement or a repeater click operable by a user, including an uncoupling lever preventing access of the click to the ratchet under the action of a reversing lever operable by a hand-setting stem, or by a main strike function or tune selection control member, or by a stopping mechanism, and including a safety device for preventing release during a strike mode or tune selection, arranged to prevent the release of any strike function by the movement or by a user, and which includes a release-prevention lever, the pivoting of which, under action on the main control member, moves any click away from the detent ratchet.
Claims19
A timepiece comprising a movement and a striking mechanism, which includes a strike drive wheel set carrying a detent ratchet which is arranged to cooperate with at least one passing strike actuation click controlled by said movement or a repeater click controlled by a user-operated, on-demand release lever, said striking mechanism including a strike-uncoupling lever able to prevent access of a said click to said detent ratchet under the action of a strike reversing lever which is operable, either by a hand-setting stem comprised in said movement, or by a main strike or tune selection control member comprised in said striking mechanism, or, in case of insufficient energy resource, by a stopping mechanism comprised in said striking mechanism, wherein said striking mechanism includes a safety device for preventing release during selection of a strike function or tune, which is arranged to prevent the release of any strike function, either by said movement or by a user, and which includes a release-prevention lever, the pivoting of which, when a strike function or tune selection is made on said main control member by a user, moves any said click away from said detent ratchet, and wherein said striking mechanism includes elastic return means for returning said main control member to a unique rest position in the absence of action by a user.
