fig. 2A, 2B and 2C show cross-sectional views of the vibration-proof device 200, the crown 100 and the vibration-proof device 200 in the second position 102, respectively, according to an embodiment of the present invention.

Detailed Description

Fig. 1A shows a shock mount 200 configured to allow movement of a timepiece movement 210 along at least three degrees of freedom, and preferably along six degrees of freedom.

The shock protection device 200 comprises said timepiece movement 210, a crown 100 connected to said timepiece movement 210 by a shaft 220, preferably a winding mechanism shaft 220, and an intermediate part 250.

Said intermediate part 250 comprises at least one shock-absorbing element 230, which shock-absorbing element 230 may cover the inside of said intermediate part 250 completely or partially and is configured to attenuate the vibrations of said timepiece movement 210 when said timepiece movement 210 moves in said intermediate part 250 along at least one of the six degrees of freedom.

In fact, as shown in fig. 1C, when said crown 100 is in contact with or close to said intermediate part 250, said at least one shock-absorbing element 230 can damp the vibrations of said timepiece movement 210, since said timepiece movement 210 can move unimpeded along the 6 degrees of freedom, but at the same time is damped by said at least one shock-absorbing element 230.

As shown in fig. 1B and 2B, crown 100 may include at least one drive mechanism 120 and at least one follower mechanism 110, such follower mechanism 110 being configured to be driven and connected to timepiece movement 210 by way of shaft 220.

The crown 100 further comprises a housing 105, the housing 105 being configured to house the at least one driven mechanism 110 and/or the at least one drive mechanism 120. More specifically, the housing 105 surrounds the at least one drive mechanism 120, which drive mechanism 120 in turn surrounds the at least one driven mechanism 110, such that the housing 105 contains the at least one driven mechanism 110 and the at least one drive mechanism 120.

When the at least one drive mechanism 120 is placed or positioned in the housing 105 of the crown 100, there is a space into which at least one protection mechanism 130 (preferably a tube 130) can be placed or inserted. In other words, the at least one protection mechanism 130 is arranged between the crown 100 and the at least one drive mechanism 120.

For waterproofing reasons, said crown 100 comprises at least one first joint 131 and at least one second joint 132. The at least one first joint 131 may be arranged between the crown 100 and the at least one protection mechanism 130, in other words, the at least one first joint 131 is configured to waterproof a space between the crown 100 and the at least one protection mechanism 130.

As is worth noting in the different figures, said at least one first joint 131 can be always in contact with said crown 100 and at least one protection means 130 and can be configured to make said space waterproof up to 30 bar, in particular up to 10 bar, preferably up to 5 bar.

Furthermore, said crown 100 is configured to move between a first position 101 and a second position 102, more specifically said at least one drive mechanism 120 is configured to move between a first position 101 and a second position 102, given that said at least one drive mechanism 120 is rigidly connected to said crown 100.

In said first position 101 (also called the disengaged position 101), said timepiece movement 210 is free to move along at least three degrees of freedom (preferably along six degrees of freedom), as shown in fig. 1A and 1C, the movement of which, even with the vibrations of said intermediate part 250, is completely, partially damped by said at least one damping element 230, which completely or partially covers said intermediate part 250. In this disengaged position 101, i.e. in said first position 101, said at least one drive mechanism 120 is remote from said at least one driven mechanism 110, but said crown 100 may contact or be close to said intermediate part 250 and/or said at least one protection mechanism 130.

As shown in fig. 1A and in particular fig. 1C, said at least one protection means 130, preferably said tube 130, is in contact with said crown 100 through at least one second joint 132. In practice, the at least one protection mechanism 130 may be in contact with the at least one second joint 132 when the at least one driving mechanism 120 is remote from the at least one driven mechanism 110.

When a user wishes to wind up a watch, said crown 100 moves towards said second position 102, i.e. said crown 100 moves away from said intermediate part 250, and timepiece movement 210 becomes rigidly connected with said crown 100, as shown in fig. 2C. At the same time, said at least one second joint 132 is removed from said at least one protection mechanism 130 by means of said crown 100, as shown in fig. 2B.

Movement from said first position 101 to said second position 102 is facilitated by at least one return mechanism 115, which return mechanism 115 optionally takes the form of at least one spring 115, which spring 115 is comprised between said crown 100 (preferably said at least one driving mechanism 120) and said at least one driven mechanism 110, thereby spacing said crown 100 from said intermediate part 250, but bringing said at least one driven mechanism 110 into contact with said at least one driving mechanism 120, as shown in fig. 2B.

The at least one driven mechanism 110 optionally takes the form of a post 110 or an end piece 113, which may include a head 113, the head 113 being configured to provide engagement with the at least one drive mechanism 120. Furthermore, according to an embodiment, said head 113 of said at least one follower 110 may be integral with or rigidly connected to said shaft 220 of said timepiece movement 210, or may be fitted to shaft 220 in the form of said end piece 113.

Furthermore, the head 113 comprises a contact surface 112 and a guiding surface 111, the guiding surface 111 being configured to guide the at least one drive mechanism 120 towards the contact surface 112 when the drive mechanism 120 is moved from the first position 101 to the second position 102 (also referred to as coupling position 102).

The cylindrical portion of the at least one driving mechanism 120 surrounding the at least one driven mechanism 110, more particularly the engagement with the at least one driving mechanism 120 provided by the contact surface 112, may allow such cooperation of the at least one driving mechanism 120 with the at least one driven mechanism 110 or such driving of the at least one driven mechanism 110 by the at least one driving mechanism 120. More specifically, the cylindrical portion of the at least one drive mechanism 120 constitutes a female mating portion of the head portion 113 of the at least one follower mechanism 110 such that the at least one drive mechanism 120 and the at least one follower mechanism 110 may be complementary, such as in the manner of a tube wrench and a hex bolt.

In the coupled position 102, i.e. in said second position 102, the user can wind said timepiece movement 210.
