Abstract
A pointer hand for a watchmaking part including a body and a cannon configured to be driven onto a cylindrical arbor, the cannon having an internal diameter that is greater than the diameter of the cylindrical arbor. The cannon includes a flat on its internal diameter that is configured to cooperate with the cylindrical arbor, to elastically deform the cannon on both sides of the flat to fix the hand onto the cylindrical arbor.
Claims11
An assembly comprising:
- a hand extension including a cylindrical arbor and a pointer hand for a watchmaking part including a body and a cannon of cylindrical shape, having an internal diameter, that is configured to be driven onto the cylindrical arbor of diameter,
- wherein an interior wall of the cannon is circular except for at least one flat that is configured to cooperate with the cylindrical arbor, and the internal diameter of the cannon measured between the at least one flat and a portion of interior wall that is circular is less than the diameter of the cylindrical arbor, to elastically deform the cannon on both sides of the at least one flat to fix the hand onto the cylindrical arbor.
An assembly comprising:
- a hand extension including a cylindrical arbor and a pointer hand for a watchmaking part including a body and a cannon of cylindrical shape, having an internal diameter, that is configured to be driven onto the cylindrical arbor of diameter,
- wherein an interior wall of the cannon is circular except for a single flat that is configured to cooperate with the cylindrical arbor, and the internal diameter of the cannon measured between the single flat and a portion of interior wall that is circular is less than the diameter of the cylindrical arbor, to elastically deform the cannon on both sides of the single flat to fix the hand onto the cylindrical arbor.
