Embodiment Construction

[0045] Figure 1A Shown is an anti-shock device 200 configured to allow movement of timepiece movement 210 along at least three degrees of freedom, preferably along six degrees of freedom.

[0046] The anti-shock device 200 comprises the timepiece movement 210 , the crown 100 connected to the timepiece movement 210 by a shaft 220 , preferably a winding shaft 220 , and a middle part 250 .

[0047] Said middle part 250 comprises at least one shock-absorbing element 230 which can completely or partially cover the inside of said middle part 250 and is configured to move along said timepiece movement 210 in said middle part 250 Vibrations of the timepiece movement 210 are damped while moving in at least one of the six degrees of freedom.

[0048] In fact, if Figure 1C As shown, when the crown 100 is in contact with or close to the middle part 250, the at least one shock-absorbing element 230 can attenuate the vibration of the timepiece movement 210, because the timepiece movement...

Abstract

A shock-proof device (200) for a movement configured to allow the movement of the horological movement (210) along at least three degrees of freedom. The shock-proof device (200) includes at least one damping element (230) configured to damp the shocks of the horological movement (210) and a crown (100) configured to move between a first position (101) where the horological movement (210) is free along at least three degrees of freedom and a second position (102) where the horological movement (210) is rigidly connected to the crown (100).

Description

technical field [0001] The present invention relates to an anti-shock device for a timepiece movement, and more particularly to a detachable crown capable of releasing said timepiece movement in six degrees of freedom. Background technique [0002] While wearing a watch, the watch movement is subjected to repeated shocks. These shocks disturb the function of the timepiece movement, which may increase its inaccuracy and lead to the loss of a few seconds. Contents of the invention [0003] The present invention proposes to solve all or some of the above-mentioned disadvantages by a crown for an anti-shock device, preferably for a timepiece movement; in the first position, the timepiece movement is free in at least three degrees of freedom, and in the second position, the timepiece movement is rigidly connected to the crown; the crown includes : [0004] - at least one driven mechanism; said at least one driven mechanism configured to be driven and connected to said timepi...
