Abstract

The invention relates to a timepiece component with a part comprising elastic attachment means and securing means arranged to be welded enabling the attachment of the elastic means to be decoupled from the securing means to ensure the welding of the timepiece component.

First claim

What is claimed is:

1. A timepiece component comprising:
a one-piece part welded on a member provided with a substantially horizontal surface and a substantially vertical surface, the one-piece part including a strip extending in a closed curve, the space delimited by the closed curve receiving the member,
wherein a lower portion of the substantially vertical surface is in direct contact with the substantially horizontal surface,
wherein the one-piece part includes a first plurality of elastic deformation portions and a second plurality of elastic deformation portions,
wherein said elastic deformation portions of said first plurality are attached to the substantially vertical surface, and
wherein said elastic deformation portions of said second plurality are welded on the substantially horizontal surface and not in direct contact with said substantially vertical surface.

2. The timepiece component according to claim 1 , wherein said first plurality of elastic deformation portions are formed by the strip whose closed curve offers elastic deformation areas that come into contact with the substantially vertical surface.

3. The timepiece component according to claim 1 , wherein said first plurality of elastic deformation portions are formed by bars integral with the strip, extending inside the space delimited by the closed curve and offering elastic deformation areas that come into contact with the substantially vertical surface.

4. The timepiece component according to claim 1 , wherein said second plurality of elastic deformation portions are formed by the strip whose closed curve offers elastic deformation portions that only come into contact with the substantially horizontal surface.

5. The timepiece component according to claim 1 , wherein said second plurality of elastic deformation portions are formed by branches integral with the strip, extending into the space delimited by the closed curve and offering elastic deformation portions that only come into contact with the substantially horizontal surface.

6. The timepiece component according to claim 1 , wherein said second plurality of elastic deformation portions are formed by branches integral with the strip, extending outside the space delimited by the closed curve and offering elastic deformation portions that only come into contact with the substantially horizontal surface.

7. The timepiece component according to claim 1 , wherein the one-piece part is made from silicon or from ceramic.

8. The timepiece component according to claim 7 , wherein the one-piece part also includes at least a partial coating of metal, silicon oxide, silicon nitride, silicon carbide or an allotrope of carbon.

9. The timepiece component according to claim 1 , wherein the member includes an iron alloy, a copper alloy, nickel or an alloy thereof, titanium or an alloy thereof, gold or an alloy thereof, silver or an alloy thereof, platinum or an alloy thereof, ruthenium or an alloy thereof, rhodium or an alloy thereof, or palladium or an alloy thereof.

10. A timepiece wherein it includes at least one timepiece component according to claim 1 .

11. The timepiece component according to claim 1 , wherein the member is a staff having a shaft forming said substantially vertical surface, said staff further having a shoulder forming said substantially horizontal surface, said shaft being inserted through said one-piece part at said substantially vertical surface.

12. The timepiece component according to claim 1 , wherein said second plurality of elastic deformation portions are deformable to adapt the one-piece part to the geometry of said substantially horizontal surface.
