Abstract
A mechanical connection device, in particular a mechanical connection device for a timepiece or a mechanical transmission device for a timepiece, includes a first part having a first area with at least a first micro-cavity; and a second part having a second area with at least a second micro-cavity, the first and second areas being in contact with one another in a mechanical connection configuration.
Claims26
A mechanical connection device, comprising:
- a first part comprising a first area with first micro-cavities;
- and
- a second part comprising a second area with second micro-cavities;
- the first and second areas being in contact with one another in a mechanical connection configuration, wherein
- the widths of the micro-cavities are less than 200 μm;
- the micro-cavities cooperate as an obstacle at their flanks imparting a friction type or a catching type mechanical connection, and wherein when a force applied by the first part to the second part exceeds a threshold, the first part slides with respect to the second part without damage;
- wherein the first part and the second part include interposed conformations separating adjacent ones of said first micro cavities of the first part and separating adjacent ones of said second micro cavities of the second part, and wherein said interposed conformations each have a top surface that is flat or planar.
