Definitions

  • the invention relates to a device for protecting a watch movement platen, at a receiving surface that includes said platen for receiving a supporting surface complementary to a mobile.
  • the invention also relates to a watch movement comprising at least one plate equipped with such a protective device for its protection during the movement of a mobile that includes this movement.
  • the invention also relates to a watch comprising such a clockwork movement.
  • the invention relates to the field of watch mechanisms.
  • Watchmaking mechanisms are highly stressed in wear, and some components, made in particular of cuprous alloy, suffer from friction with an antagonistic component of harder material, steel alloy for example.
  • a rod actuated by the crown causes, by a radial guide, a winding pinion which meshes with a gear wheel transmitting rotation to a barrel ratchet, directly or through a gear train.
  • This winding pinion usually made of steel, is axially guided in support on a singing of the movement plate, usually brass or the like. Wear occurs quickly in this contact area, and may require the replacement of the plate, which is expensive.
  • the invention proposes to change at a lower cost an existing plate to ensure a longevity equivalent to other components of the watch or the timepiece.
  • the invention relates to a device for protecting a watch movement platen, at a receiving surface that includes said platen for receiving a bearing surface complementary to a support surface.
  • mobile device characterized in that said device comprises at least one insert having a sliding surface surface hardness greater than that of said plate, and attached to or in said plate so that said sliding surface coincides with said surface of reception.
  • said insert is positioned, or in abutment on at least one bearing surface of said platen, or in a housing of said platen.
  • said plate comprises at least a first indexing surface arranged to cooperate in abutment with a first indexing surface that comprises said insert.
  • the invention relates to the field of watchmaking mechanisms, in which a mobile in operation is supported on a surface of another component, which will be called platinum here.
  • mobile any watch component mounted to rotate or / and translation in a mechanism.
  • the invention is not limited to the case of a platinum in the usual sense of the term, but relates to any watch movement component, or any component of clockwork, subject to wear by friction.
  • the invention relates to a device 1 for protecting a turntable 2 of a watch movement 3, at a geometric receiving surface 4 that comprises this plate 2 for receiving a complementary bearing surface 51 of a mobile 5.
  • this device 1 comprises at least one insert 6.
  • This insert 6 has a sliding surface 7 of superficial hardness greater than that of the plate 2, and is attached to or in the plate 2, so that its sliding surface 7 coincides geometrically with the theoretical receiving surface 4.
  • This insert 6 is preferably positioned, or supported on at least one bearing surface 20 of the plate 2 as visible on the Figures 1 to 4 , or in a housing 8 of the plate 2 as visible on the figure 8 .
  • the insert 6 is not secured to the plate 2, which allows its possible replacement.
  • the plate 2 comprises at least a first indexing surface 21, which is arranged to cooperate in abutment with a first complementary indexing surface 61 that the insert 6 comprises.
  • the insert 61 comprises a single complementary indexing surface 61, which is made in plane form, as visible on the figure 5 the first indexing surface 21 is then a platinum part. It is thus easy to index the insert 6 angularly relative to the plate 2, and to define its relative position, here in the direction C of the figure 1 .
  • the plate 2 has a bore 29, and the insert 6 has a bore 69, it is thus easy to position them relative to each other, and in particular to put them in the same plan if we are looking for alignment.
  • the insert 6 is centered in a recess 2 of the mobile 5, here a winding pinion.
  • the device 1 is designed for vertical mounting, that is to say say according to direction C of the figure 1 , which is very simple and requires no pre-assembly of the insert on the plate 2.
  • the material of the insert 6 may be selected from copper alloys, steels alloys, synthetic materials, artificial rubies, or others.
  • the insert 6 visible on the Figures 1 to 5 comprises a main body of revolution 64 in the form of a washer, carrying at least one bore 69, and protruding from this body 64, a boss 65 comprising such a complementary indexing surface 61.
  • the insert 6 is thus outlined under form of a low-cut washer, and is finished with a simple milling delimiting, on the one hand, the complementary indexing surface 61, and on the other hand a complementary bearing surface 60 intended to bear on the bearing surface 20 of the plate 2. It is also possible to produce this insert 6 by stamping, or by plastic injection. It is just as easy to transform an existing plate, by lateral milling a clearance corresponding to the thickness E of the body 64 of the insert 6, and by possible surface milling of the first indexing surface 21, in the case where the platinum 2 considered is not flat in this area.
  • the plate 2 comprises at least one second indexing surface 22 arranged to cooperate in abutment with a second complementary indexing surface 62 that the insert 6 comprises.
  • the second indexing surface 22 is distinct from the first indexing surface 21, and the second complementary indexing surface 62 is distinct from the first complementary indexing surface 61.
  • the second indexing surface 22 is flat and oblique with respect to said first indexing surface 21 which is flat, and the second complementary indexing surface 62 is flat and oblique with respect to the first complementary indexing surface 61 which is flat.
  • the second indexing surface 22 is perpendicular to the first indexing surface 21, and the second complementary indexing surface 62 is perpendicular to the first complementary indexing surface 61.
  • the figure 7 illustrates yet another variant of insert 6 having two angular indexing faces 61 and 62 perpendicular to one another, and a third face 63 parallel to one of them 62.
  • the plate 2 comprises at least one bore 29 along an axis D for the pivotal guidance of a rod 9
  • the use of an insert 6 according to the invention can it, in addition to the protection of the edge face of the plate 2, to less wear wear this bore 29 of the plate, ensuring at least one range guiding such a rod 9.
  • the insert 6 advantageously comprises at least one bore 69 for the pivotal guidance of a rod 9.
  • this bore 69 is treated or coated with an anti-wear treatment or coating, or insert 6 is equipped with a ring, having the bore 69, this ring being of a suitable material or treated or coated with a treatment or anti-wear coating.
  • the device 1 is advantageously used in a mechanism where the bore 69 of the insert 6 and the bore 29 of the plate 2 are aligned in the assembly position of the insert 6 on the plate 2.
  • the clockwork 3, or the device 1 is preferably arranged to receive, in the same insertion direction during assembly, the insert 6 and the mobile 5, preferably perpendicular to the axis D and according to direction C of the figure 1 , and comprises a chamber 80 in which at least the insert 6 is movable in a plane perpendicular to the axis D in the absence of a rod 9, and wherein the insert 6 is immobilized in a single position when the insertion of such a rod 9 into the bore 69 of the insert 6 and the bore 29 of the plate 2.
  • the sliding surface 7 of the insert 6 is preferably perpendicular to the axis D.
  • the device 1 is part of a winding mechanism 10 of a watch 30, the mobile 5 is a winding pinion, and the plate 2 has a bore 29 along an axis D for the guidance in pivoting of a winding stem 9, which is also guided in a bore 69 of the insert 6 when the latter is in the bearing and abutment position on the plate 2 for the pivotal guidance of such a stem 9.
  • the invention also relates to a watch movement 3 comprising at least one plate 2 equipped with such a protection device 1 for its protection during the movement of a mobile 5 that includes this movement 3, and whose insert 6 is , or kept in the plate 2 by a rod 9 inserted into a bore 29 of axis D of the plate and into a bore 69 of this insert 6 aligned with the bore 29 of the plate 2, or movable relative to the plate 2 in a plane perpendicular to the axis D.
  • the invention also relates to a watch 30 comprising such a watch movement 3.
  • the invention eliminates the wear of the platen, in particular in a manual winding mechanism. It allows the reuse of a platinum existing at the cost of tiny transformations, with a very inexpensive implementation insert. The only after-sales interventions concern the insert, not the platinum.
