Abstract
Abstract A shock absorbing bearing for timepieces and small mechanical apparatus including a plastic bearing body of disc-like configuration having a peripheral thin ring shaped portion secured to a bearing support and a central thickening having a bearing surface. A recess is formed in said thickening opening to the bearing surface for receiving the end of a shaft. The bearing surface has a frusto-conical configuration and the bearing support has a seat of conforming configuration to assure centering. Axial shocks are absorbed by the elastic deformation of the ring shaped portion and lateral shocks are absorbed by elastic deformation of the thickening.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
110 words
A shock absorbing bearing for timepieces and small mechanical apparatus which includes a shaft engageable with said bearing; said bearing comprising, a unitary bearing body formed of plastic material and having an axial-shock absorbing thin outer ring and a lateral-shock absorbing thickened central portion, said ring and thickened portion being elastically deformable, a bearing support for receiving said bearing body and means for securing said bearing body to said bearing support at the periphery of said ring, said central thickened portion having an axial recess for receiving the shaft end, the axial thickness of said bearing body at said recess being substantially greater than the ring thickness at its periphery.
Claim 2
Dependent Claim
110 words
A shock absorbing bearing for timepieces and small mechanical apparatus which includes a shaft engageable with said bearing; said bearing comprising, a unitary bearing body formed of plastic material and having an axial-shock absorbing thin outer ring and a lateral-shock absorbing thickened central portion, said ring and thickened portion being elastically deformable, a bearing support for receiving said bearing body and means for securing said bearing body to said bearing support at the periphery of said ring, said central thickened portion having an axial recess for receiving the shaft end, the axial thickness of said bearing body at said recess being substantially greater than the ring thickness at its periphery.
Claim 3
Dependent Claim
56 words
The bearing as claimed in claim 1 wherein said bearing support has an axial passage and said thickened central portion has a centering cavity having a coaxial frustoconical surface, said bearing support having an axial seat of conforming configuration, said centering cavity opening to said axial passage and said axial recess opening to said central cavity.
