Patent ID: 8579501

Claim:
An anti-shock device for the protection of a timepiece component, made of material that is at least partially magnetically permeable, or respectively at least partially magnetic, and/or of material that is at least partially conductive, or respectively at least partially electrized, wherein said component is pivotally mounted in a chamber between a first end and a second end of said component, wherein said anti-shock device includes, on both sides of said first and second ends, on the one hand, means for attracting said first end to keep said first end abutting on a first pole piece, and on the other hand, in proximity to a second pole piece, means for attracting said second end towards said second pole piece, and wherein said means for attracting said first end, on the one hand and said means for attracting said second end, on the other hand, can move along an axial direction between stop members, and further wherein said first pole piece and said second pole piece are distinct from said component, and are each located on the periphery of or in proximity to said chamber, and are each made of material that is at least partially magnetic, or respectively at least partially magnetically permeable, and/or of material that is at least partially electrized or respectively at least partially conductive, and further wherein said component is freely mounted inside said chamber between said pole pieces, so as to rest on a support surface in proximity to only one of said pole pieces.
