Abstract
A balance for a horological movement, including rigid parts including a hub defining the pivot axis of the balance, a felloe sector, at least one arm connecting the felloe sector to the hub, and including a slot for receiving and gripping an inertia-block in position, the slot opening into a housing delimited on the one hand by a rigid part of the balance, and on the other hand an elastic arm including a first end integral with a rigid part of the balance, and a second free distal end. The elastic arm has a hook-shaped body, the free distal end of the hook being parallel to a part of the balance having a rigidity greater than or equal to that of the elastic arm.
Claims15
A balance for a horological movement, comprising rigid parts consisting of a hub defining the pivot axis of said balance, at least one felloe sector, at least one arm connecting said at least one felloe sector to said hub, and including at least one slot for receiving and gripping an inertia-block in position, said at least one slot opening into a housing delimited on the one hand by a rigid part of said balance, and on the other hand an elastic arm including a first end integral with the felloe of said balance, and a second distal end free relative to said hub, to said arm, and to said felloe sector,
- wherein said elastic arm comprises a hook-shaped body, the free distal end of the hook being parallel to a part of the balance having a rigidity greater than or equal to that of the elastic arm.
The balance according to claim, wherein said at least one elastic arm is made in one piece with the balance.
