Abstract
A device for elastic guidance in rotation for a timepiece mechanism allows rotation of one element relative to another element about an axis of rotation Z defining an axial direction. The device includes construction blades that each includes an assembly fixing part having a body and a functional part extending from the body as far as one end. The assembly fixing part and the functional part are separated by at least one slot in at least two extensions which are elastically connected and extend in a radial direction transverse to the axial direction. The device also includes anchorage zones which are disposed at opposite axial ends of the flexible guidance device, and configured to be fixed to the elements.

A device for elastic guidance in rotation for a timepiece mechanism allowing rotation of one element relative to another element about an axis of rotation Z defining an axial direction, the device comprising:
- construction blades, each construction blade comprises an assembly fixing part comprising a body and a functional part extending from the body as far as one end, the assembly fixing part and the functional part being separated by at least one slot in at least two extensions which are elastically connected and extend in a radial direction transverse to the axial direction, the device comprising furthermore anchorage zones which are disposed at opposite axial ends of the flexible guidance device, and configured to be fixed to said elements, wherein the assembly fixing part of each of the construction blades comprises a cavity or an assembly recess and an assembly extension which intersect and which fit together in a radial direction in order to be locked together.
A watch movement comprising:
- a device for elastic guidance in rotation for a timepiece mechanism allowing rotation of one element relative to another element about an axis of rotation Z defining an axial direction, comprising construction blades, each construction blade comprises an assembly fixing part comprising a body and a functional part extending from the body as far as one end, the assembly fixing part and the functional part being separated by at least one slot in at least two extensions which are elastically connected and extend in a radial direction transverse to the axial direction, the device comprising furthermore anchorage zones which are disposed at opposite axial ends of the flexible guidance device, and configured to be fixed to said elements, wherein the assembly fixing part of each of the construction blades comprises a cavity or an assembly recess and an assembly extension which intersect and which fit together in a radial direction in order to be locked together.
