Description

BRIEF DESCRIPTION OF THE FIGURES

(1) The invention will be described hereinafter in more detail using the appended drawings, given as non-restrictive examples, wherein:

(2) FIGS. 1A, 1B and 10 show, respectively, a shock-proof device 200, a crown 100 and a sectional view of said shock-proof device 200 in a first position 101 according to an embodiment of the invention; and,

(3) FIGS. 2A, 2B and 2C show, respectively, said shock-proof device 200, said crown 100 and a sectional view of said shock-proof device 200 in a first position 101 according to an embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

(4) FIG. 1A shows a shock-proof device 200 configured to allow the movement of a horological movement 210 along at least three degrees of freedom, preferably along six degrees of freedom.

(5) Said shock-proof device 200 comprises said horological movement 210, a crown 100 connected by a shaft 220, preferably a winding-mechanism shaft 220, to said horological movement 210 and a middle 250.

(6) Said middle 250 includes at least one damping element 230 which can completely or partially cover the inside of said middle 250 and is configured to damp the shocks of said horological movement 210 when said horological movement 210 moves along at least one of the 6 degrees of freedom in said middle 250.

(7) Indeed, as seen in FIG. 10, said at least one damping element 230 can damp the shocks of said horological movement 210 when said crown 100 is contact with or near said middle 250, as said horological movement 210 can move along the 6 degrees of freedom without being impeded but while being damped by said at least one damping element 230.

(8) Represented in FIGS. 1B and 2B, said crown 100 can comprise at least one driving organ 120 and at least one driven organ 110 configured to be driven and to be connected to said horological movement 210 by said shaft 220.

(9) Said crown 100 also includes an enclosure 105 configured to receive said at least one driven organ 110 and/or said at least one driving organ 120. More specifically, said enclosure 105 surrounds said at least one driving organ 120, which in turn surrounds said at least one driven organ 110 such that said enclosure 105 contains said at least one driven organ 110 and said at least one driving organ 120.

(10) When said at least one driving organ 120 is placed or is located in said enclosure 105 of said crown 100, there is a space wherein at least one protective organ 130, preferably a tube 130, can slot into or be inserted. In other words, said at least one protective organ 130 is disposed between said crown 100 and said at least one driving organ 120.

(11) For water-resistance reasons, said crown 100 comprises at least a first joint 131 and at least a second joint 132. Said at least a first joint 131 can be disposed between said crown 100 and said at least one protective organ 130, in other words, said at least a first joint 131 is configured to render the space between said crown 100 and said at least one protective organ 130 water-resistant.

(12) As is noteworthy in the different figures, said at least a first joint 131 can always be in contact with said crown 100 and at least one protective organ 130, and can be configured to render said space water-resistant up to 30 bar, particularly up to 10 bar, preferably up to 5 bar.

(13) Moreover, said crown 100 is configured to move between a first position 101 and a second position 102, more particularly and given that said at least one driving organ 120 is rigidly connected to said crown 100, it is said at least one driving organ 120, which is configured to move between a first position 101 and a second position 102.

(14) In said first position 101 also referred to as disconnected position 101, said horological movement 210 is free along at least three degrees of freedom, preferable along six degrees of freedom, FIGS. 1A and 10, and the movements thereof, even the shocks thereof with said middle 250, are completely and partially damped by said at least one damping element 230 completely or partially covering said middle 250. In this disconnected position 101, i.e. in said first position 101, said at least one driving organ 120 is distant from said at least one driven organ 110, but said crown 100 can be in contact with or near said middle 250 and/or said at least one protective organ 130.

(15) As seen in FIG. 1A, and more particularly in FIG. 10, said at least one protective organ 130, preferably said tube 130 is in contact with said crown 100 by means of at least a second joint 132. Indeed, said at least one protective organ 130 can be in contact with said at least a second joint 132 when said at least one driving organ 120 is distant from said at least one driven organ 110.

(16) When the user wishes to wind their watch, said crown 100 is moved towards said second position 102, i.e. said crown 100 is moved away from said middle 250, and horological movement 210 becomes rigidly connected to said crown 100, FIG. 2C. Simultaneously, said at least a second joint 132 is moved away, by means of said crown 100, from said at least one protective organ 130, FIG. 2B.

(17) This movement from said first position 101 towards said second position 102 can be facilitated by at least one return organ 115, optionally taking the form of at least one spring 115, comprised between said crown 100, preferably said at least one driving organ 120, and said at least one driven organ 110, so as to distance said crown 100 from said middle 250 but to bring said at least one driven organ 110 and said at least one driving organ 120 into contact, FIG. 2B.

(18) Said at least one driven organ 110, optionally taking the form of a post 110 or an end piece 113, can comprise a head 113 configured to offer an engagement to said at least one driving organ 120. Moreover, according to the embodiments, said head 113 of said at least one driven organ 110 can be integral, or rigidly connected, with said shaft 220 of said horological movement 210 or, in the form of said end piece 113, can be fitted onto the shaft 220.

(19) Furthermore, said head 113 comprises a contact surface 112 and a guiding surface 111 configured to guide said at least one driving organ 120 towards said contact surface 112, when said driving organ 120 moves from said first position 101 towards said second position 102, also referred to as coupling position 102.

(20) This cooperation or this driving of said at least one driven organ 110 by said at least one driving organ 120 may be permitted by the cylindrical shape of said at least one driving organ 120 which surrounds said at least one driven organ 110 and more particularly, by the engagement offered by said contact surface 112 to said at least one driving organ 120. More specifically, said cylindrical shape of said at least one driving organ 120 forms a female match of said head 113 of said at least one driven organ 110, such that a complementarity between said at least one driving organ 120 and said at least one driven organ 110 is possible, in the manner of a tube wrench and a hexagonal bolt for example.

(21) In the coupling position 102, i.e. in said second position 102, the user can wind said horological movement 210.
