Definitions
- the invention relates to an orientable screwed crown for a watch case comprising a middle part with at least one through housing for receiving said orientable screwed crown, which orientable screwed crown is arranged to cooperate with said housing and seal it in a sealed manner, said orientable screwed crown comprising a pattern on an end face or in its vicinity, said orientable screwed crown comprising, movable axially in an axial direction with respect to each other, on the one hand a sub-assembly comprising a crown body that can be handled by a user and comprising said pattern, and on the other hand a tube arranged to be screwed or driven into said housing in said axial direction.
- the invention also relates to a watch case, comprising a middle part with at least one through housing for receiving such an orientable screw-down crown.
- the invention also relates to a timepiece, in particular a watch, comprising such a case.
- the invention also relates to a method of assembling such an orientable screwed crown.
- the invention also relates to a method for mounting such an orientable screwed crown on a watch case.
- Screw-down crowns are commonly used to equip watches with the aim of improving their sealing at the passage of a control member, such as a winding or control rod.
- This type of crown has the particularity of being able to take an unscrewed position in which the watch can be wound, time-set, adjusted, or other, and a screwed position in which the crown is screwed and blocked on a driven or screwed tube. in the middle of the watch case in order to compress a gasket, thus improving the watertightness of the watch.
- the screwed position is therefore that which corresponds to the normal position when the watch is worn and which is always roughly the same, apart from the wear of the seal.
- the known mounting methods generally do not allow the crown to be brought into a determined orientation with respect to the case after it has been screwed in, which can be detrimental to the aesthetics of the case. This situation is of course unacceptable when these crowns equip luxury and high quality products.
- the object of the invention is in particular to overcome the various drawbacks of these known techniques.
- an objective of the invention is to provide an orientable screwed crown adaptable to any watch case comprising a crown housing, for the orientation of this screwed crown, produced according to a simple and economical construction.
- Another objective of the invention is to provide an orientable screwed crown that is more reliable than existing ones.
- the invention relates to an orientable screwed crown according to claim 1.
- the invention also relates to a watch case, comprising a middle part with at least one through housing for receiving such an orientable screw-down crown.
- the invention also relates to a timepiece, in particular a watch, comprising such a case.
- the invention also relates to a method of assembling such an orientable screwed crown.
- the invention also relates to a method for mounting such an orientable screwed crown on a watch case.
- the invention relates to an orientable screw-down crown 10 for a watch case 100.
- This case 100 conventionally comprises a caseband 9, with at least one through housing 90 for receiving the rotatable screw-down crown 200.
- This orientable screwed crown 10 is arranged to cooperate with the housing 90 and to close it in a leaktight manner.
- the orientable screwed crown 10 comprises a pattern 19 on an end face 18 or in its vicinity.
- This orientable screwed crown 10 comprises, movable axially in an axial direction D with respect to one another, on the one hand a sub-assembly 20 comprising a crown body 1 which can be handled by a user and comprising the pattern 19, and on the other hand a tube 9.
- This tube 9 is arranged to be screwed or driven into the housing 90 in the axial direction D.
- the sub-assembly 20 comprises, integral with the crown body 1, a front indexing relief 15.
- This front indexing relief 15 extends substantially radially with respect to the axial direction D, and is arranged in order, in an engaged position, to cooperate frontally in a complementary manner, in the axial direction D, with a complementary front indexing relief 35 which comprises a fixed barrel 3, which the sub-assembly 20 comprises.
- This complementary indexing front relief 35 extends substantially radially with respect to the axial direction D, and the fixed barrel 3 tends to be biased towards the crown body 1 by at least one crown spring 4, which is interposed and mounted prisoner between the crown body 1 and the fixed barrel 3 which it tends to bring closer to one another.
- the front indexing relief 15 remains at a distance from the complementary indexing front relief 35 and without cooperation with him.
- the cooperation between the front indexing relief 15 and the complementary indexing front relief 35 defines a discrete number of relative indexing positions corresponding to as many relative orientations of the pattern 19 with respect to the box 100.
- the sub-assembly 20 and the tube 9 are arranged to cooperate by screwing up to a stop position corresponding to a completely screwed position of the sub-assembly 20 in the tube 9,
- the sub-assembly 20 also comprises a first axial stop means 8, which is fixed to the crown body 1, to trap axially, in the axial direction D, the sub-assembly 20 with a corresponding axial stroke. to the range of deformation of the crown spring 4, to allow disengagement, by pulling the crown body 1, between the front indexing relief 15 and the complementary indexing front relief 35.
- the crown spring 4 is a helical spring. In the absence of manipulation by the user, that is to say in the engaged position, the crown spring 4 tends to bring the crown body 1 closer to the fixed barrel 5.
- the sub-assembly 20 comprises a movable barrel 7, which comprises fixing means 71 arranged for fixing the orientable screwed crown 10 to a control member housed in a box 100.
- This movable barrel 7 is movable axially along the axial direction D against elastic return means 5 in a chamber 31, which is delimited on the one hand by the fixed barrel 3 and on the other hand by the crown body 1 or by a ring 2 integral with the body crown 1, or by a journal 13 integral with the crown body 1, and in which chamber 31 the movable barrel 7 is mounted captive.
- the elastic return means 5 comprise at least one tube spring, in particular helical.
- This journal 13, here shown in the figures in one piece with the crown body 1, can also be an attached element, permanently attached to the body of crown 1, for example by laser welding or the like.
- the ring 2 can also be fixed to the crown body 1 by a laser weld 21, or the like.
- the sub-assembly 20 cannot be dismantled.
- the fixed barrel 3 comprises a thread 31, which is arranged to cooperate with an internal thread 91 which the tube 9 comprises.
- front indexing relief 15 and the complementary indexing front relief 35 include complementary front teeth.
- the first axial stop means 8 comprises an annular ring with a front abutment bearing surface 81, which is substantially perpendicular to the axial direction D, and arranged to cooperate in abutment bearing with the crown spring 4 , or with one of them if there is more than one.
- the first axial stop means 8 comprises at least one annular groove 82 for receiving a seal 6, which is arranged to cooperate with a seal bearing surface 92 which the tube 9 comprises and which is arranged to compress the seal 6 in the fully screwed position of the sub-assembly 20 in the tube 9.
- this seal bearing surface 92 is oblique with respect to the axial direction D, in particular conical or the like.
- the annular ring 8 can also be fixed to the crown body 1 by laser welding 83, or the like.
- the figures illustrate a particular variant where the crown body 1 comprises a groove 180, intended to receive an adhesive seal or the like.
- the front indexing relief 15 is carried by a ring 2 integral with the crown body 1, which makes it possible to lower the cost of production.
- the invention also relates to a watch case 100, comprising a middle part 110 with at least one through housing 90 for receiving such an orientable screwed crown 10.
- the invention also relates to a timepiece, in particular a watch 1000, comprising such a box 100.
