Shock absorber body for a balance of a horological oscillator

摘要

A shock-absorber body (11) for an assembled balance (6) of a horological oscillator (8), comprising a guiding portion (11a) for the shock-absorber body (1) for its mounting on a bridge (2) and a fastening element (13) for an outer end of a spiral spring (5) of the oscillator.

主权项

1. A shock-absorber body configured for an assembled balance of a horological oscillator, comprising:
(i) a guiding portion for mounting the shock-absorber body on a bridge, wherein the guiding portion comprises a rotational driving zone about a longitudinal axis of the shock-absorber body, the zone comprising a conformation to allow the shock-absorber body to be driven in rotation, wherein the rotational driving zone includes a peripheral outwardly-oriented cylindrical surface symmetrical around a longitudinal axis, (ii) at least one shoulder extending outwardly relative to the peripheral cylindrical surface, and (iii) a fastening element for fastening an outer end of a spiral spring of the oscillator to the shock-absorber body, wherein the fastening element is integrally mounted with the guiding portion, so that the fastening element is positioned by positioning the guiding portion of the shock-absorber body, wherein the guiding portion is configured to be positioned by rotating the shock-absorber body relative to a balance bridge.
