Abstract
A timekeeping pivot linking a first part with a second part, pivotably about a pivot axis, the pivot comprising a blade having an edge, rigidly connected to one of the first or second parts and the median plane of which passing via the edge defines a blade plane, and a bearing area rigidly connected to the other of the first and second parts and against which the edge of the blade bears, the contact points of the blade and of the bearing area being substantially situated on the pivot axis, the first and second parts being rigidly connected in translation in the direction orthogonal to the pivot axis contained in the blade plane.
Claims15
A timekeeper pivot comprising a first part and a second part pivotally connected around a pivot axis, the pivot including at least one blade provided with an edge, the blade secured to one of the first or second parts and the median plane of which passing through the edge defines a blade plane, and a groove secured to the other of the first and second parts and against a bottom surface of the groove which bears the edge of the blade, the contact points of the blade and of the bottom surface of the groove being located on the axis of the pivot, wherein the first and second parts are secured in translation along a direction orthogonal to the axis of the pivot contained in the blade plane further comprising a spike for limiting the relative displacement of the first and second parts in translation along the pivot axis.
