Abstract
A mechanism for a timepiece, comprising a an oscillating regulator mechanism, a rotary energy distribution toothed wheel, a blocking mechanism controlled by the regulator mechanism to alternatively hold and release the energy distribution wheel, and a monostable elastic member linked to the regulator mechanism and bearing on the teeth of the energy distribution wheel. The teeth of the energy distribution wheel are adapted to elastically deform the monostable elastic member by cam effect during rotation of the wheel, and the monostable elastic member is adapted to elastically return to its rest position, thus releasing mechanical energy to the regulator mechanism.
Claims24
A mechanism for a timepiece, comprising:
- a regulator mechanism adapted to oscillate with a periodical movement;
- an energy distribution member having teeth;
- a blocking mechanism cooperating with the energy distribution member, said blocking mechanism being controlled by the regulator mechanism to regularly and alternatively hold and release the energy distribution member so that said energy distribution member may move step by step according to a repetitive movement cycle;
- a monostable elastic member linked to the regulator mechanism and adapted to bear on the teeth of the energy distribution member, said monostable elastic member normally having a first geometrical configuration, said monostable elastic member being arranged such that during each movement cycle of the energy distribution member:
- one tooth of said energy distribution member elastically deforms said monostable elastic member from said first geometrical configuration;
- and then said monostable elastic member elastically returns to the first geometrical configuration, thereby releasing mechanical energy to the regulator mechanism
- wherein the regulator mechanism has an inertial regulating member which is mounted on a support by a first elastic suspension and the blocking mechanism has a blocking member which is connected to the regulating member by at least an elastic link so as to move in synchronism with said regulating member, said blocking member being connected to the monostable elastic member and cooperating with the energy distribution member to alternatively hold and release said energy distribution member.

- said mechanism including a fixed stop having a predetermined position relative to a support on which the energy distribution member is mounted,
- wherein the monostable elastic member is connected to a decoupled support which is elastically linked to the regulator mechanism by an elastic connection,
- wherein said stop is positioned so as to stop said decoupled support as long as one tooth of said energy distribution member elastically deforms said monostable elastic member from said first geometrical configuration,
- and wherein said elastic connection is rigid enough to maintain said decoupled support in abutment with said stop while said energy distribution member elastically deforms said monostable elastic member.
