Abstract

A timepiece regulator comprising an inertial regulating member which is mounted on a support by an elastic suspension so as to be able to oscillate in translation, along a main direction of translation.

First claim

The invention claimed is:

1. A timepiece movement having a timepiece regulator and a blocking mechanism,
said timepiece regulator comprising at least one inertial regulating member which is mounted on a support by an elastic suspension so as to be able to oscillate, wherein the regulating member is mounted on the support to oscillate in translation, along a main direction of translation,
said blocking mechanism having a blocking member being controlled by the regulating member to be able to regularly and alternatively hold and release a movable energy distribution member so that said energy distribution member moves by steps, said blocking mechanism being further adapted to regularly release energy to the regulating member for maintaining oscillation of said regulating member,
said blocking member being connected to said regulating member by at least one first elastic link,
wherein said elastic suspension includes at least two second elastic links extending substantially in a second direction substantially perpendicular to the main direction of translation, each second elastic link extending between a first end unitary with the support and a second end unitary with the inertial regulating member.

2. The timepiece movement according to claim 1 , wherein the regulating member is mounted on the support to oscillate in substantially rectilinear translation.

3. The timepiece movement according to claim 1 , wherein the regulating member is mounted on the support to oscillate in circular translation, with a first amplitude of oscillation in the main direction of translation and a non-zero, second amplitude of oscillation in said second direction, the first amplitude being larger than the second amplitude.

4. The timepiece movement according to claim 3 , wherein the first amplitude of oscillation is at least 10 times larger than the second amplitude.

5. A timepiece regulator according to claim 1 , comprising two inertial regulating members which are linked together such that said regulating members always have symmetrical an opposed movements in the main direction of translation.

6. A timepiece regulator according to claim 5 , wherein the two inertial regulating members are linked together by a balance lever which is pivotally mounted with respect to the support.

7. The timepiece movement according to claim 1 , wherein the timepiece regulator and blocking member forma monolithic part made in a single plate.

8. The timepiece movement according to claim 1 , further comprising said movable energy distribution member, said movable energy distribution member being a rotative wheel having external teeth adapted to cooperate with said blocking member.

9. A timepiece having a timepiece movement according to claim 1 .

10. The timepiece movement according to claim 1 , wherein said blocking member is connected to said support by at least one elastic branch extending substantially in the first direction and adapted to guide said blocking member for movement in the second direction.

11. The timepiece movement according to claim 10 , said movable energy distribution member is a rotative wheel having external teeth and
wherein said blocking member includes two spaced-apart stop members which are substantially opposed in the second direction and which are adapted to, in turn, stop and release said external teeth of the rotative wheel.

12. The timepiece movement according to claim 1 , wherein said blocking member is connected to said regulating member by two first elastic links extending substantially in the second direction.

13. The timepiece movement according to claim 12 , wherein said blocking member is connected to said support by two elastic branches extending substantially in the first direction and adapted to guide said blocking member for movement in the second direction.
