Abstract
A timepiece indexing element cooperating coaxially with a component including an indexing relief element defining indexing positions, including a first bearing surface cooperating in abutment with the component, elastic return device exerting a radial thrust on this component to press it onto this first bearing surface, and indexing device cooperating with the indexing relief element, these elastic return devices include at least a first elastic arm including a first indexing surface comprised in this indexing device and arranged to exert a radial thrust force on the component and, at least a second elastic arm arranged to exert a radial thrust force on the first elastic arm.
Claims22
A timepiece indexing element, arranged to cooperate in a substantially coaxial manner, about an axis about which said indexing element extends, with a timepiece component comprising an indexing relief element defining a plurality of indexing positions, said indexing element comprising a first bearing surface arranged to cooperate in abutment with a second complementary bearing surface comprised in said component, and comprising elastic return means arranged to exert a substantially radial thrust force, with respect to said axis, on said component, to press said component onto said first bearing surface, and comprising indexing means arranged to cooperate with said indexing relief element of said component for relative indexing between said indexing element and said component, wherein said elastic return means comprise at least a first elastic arm comprising a first indexing surface comprised in said indexing means and which is arranged to exert a substantially radial thrust force with respect to said axis on said component, and at least a second elastic arm arranged to exert a substantially radial thrust force with respect to said axis on said at least one first elastic arm.
