Timepiece dial provided with a three-dimensional decoration
A dial for a timepiece, such as a watch, includes at least one three-dimensional decoration offset away from a base plate which forms part of the dial. The decoration is mounted on the base plate by an assembly of elements including a fixing screw, a support bar including a proximal end secured to the base plate by the fixing screw and a distal end attached to a first point of the lower surface of the decoration, a support foot including a proximal end held in a fixed position in the plate of the base plate and a distal end attached to a second point of the lower surface of the decoration, and a spacer which forms a lateral connection between the fixing screw and the support foot, the spacer being secured with the support bar to the base plate by the fixing screw.
1. A dial for a timepiece, the dial comprising:
a base plate provided with at least one three-dimensional decoration offset away from the base plate, the decoration comprising a lower surface arranged on a side of the base plate and an upper surface opposite the lower surface, wherein the decoration is mounted on the base plate by an assembly of elements comprising:
a fixing screw screwed into a threaded hole arranged in the base plate,
a support bar comprising a proximal end secured to the base plate by the fixing screw and a distal end attached to a first point of the lower surface of the decoration, a projection of the first point in a plane of the base plate being away from the fixing screw,
a support foot having a proximal end held in a fixed position in the plane of the base plate and a distal end attached at a second point of the lower surface of the decoration, a projection of the second point in the plane of the base plate being away from the fixing screw and from the projection of the first point, and
a spacer which forms a lateral connection between the fixing screw and the support foot, the spacer being secured with the support bar to the base plate by the fixing screw.
2. The dial according to claim 1 , wherein the positions of the fixing screw and of the projections of the first and second points form a triangle in the plane of the base plate.
3. The dial according to claim 1 , wherein the support foot comprises an arbor whose distal end is attached to the lower surface of the decoration, and wherein the spacer is provided with a through hole for the passage of the arbor.
4. The dial according to claim 3 , wherein the proximal end of the arbor is formed of a portion of increased cross-section which is embedded in a cavity made in the base plate, in order to hold the portion of increased cross-section in a fixed position in the plane of the base plate.
5. The dial according to claim 4 , wherein the spacer holds the portion of increased cross-section inside the cavity.
6. The dial according to claim 4 , wherein the assembly further comprises a part made from a shock absorber material between the portion of increased cross-section and the bottom of the cavity.
7. The dial according to claim 3 , wherein the arbor is essentially perpendicular with respect to the plane of the base plate.
8. The dial according to claim 7 , wherein the arbor is a supplementary screw, whose portion of increased cross-section foil is a screw head, and wherein the second point of the lower surface of the decoration is provided with a threaded hole into which the distal end of the supplementary screw is screwed.
9. The dial according to claim 8 , wherein the support foot further comprises a tube which surrounds one portion of the supplementary screw and wherein the tube is gripped between the spacer and the lower surface of the decoration by the force exerted by the engagement of the supplementary screw in the threaded hole provided in the lower surface of the decoration.
10. The dial according to claim 1 , wherein the support bar comprises an am inclined with respect to the plane of the base plate.
11. The dial according to claim 1 , wherein the proximal end of the support bar comprises a first plate embedded in a first cavity made in the base plate, the threaded hole arranged in the base plate being at the bottom of said first cavity wherein the first plate is embedded.
12. The dial according to claim 1 , wherein the distal end of the support bar comprises a second plate embedded in a second cavity made in the lower surface of the decoration.
13. The dial according to claim 1 , wherein the distal end of the support bar is attached to the lower surface of the decoration by welding or adhesive bonding.
14. A timepiece comprising:
a dial for a timepiece, the dial comprising a base plate provided with at least one three-dimensional decoration offset away from the base plate, the decoration comprising a lower surface arranged on a side of the base plate and an upper surface opposite the lower surface, wherein the decoration is mounted on the base plate by an assembly of elements comprising:
a fixing screw screwed into a threaded hole arranged in the base plate,
a support bar comprising a proximal end secured to the base plate by the fixing screw and a distal end attached to a first point of the lower surface of the decoration, a projection of the first point in a plane of the base plate being away from the fixing screw, and
a support foot having a proximal end held in a fixed position in the plane of the base plate and a distal end attached at a second point of the lower surface of the decoration, a projection of the second point in the plane of the base plate being away from the fixing screw and from the projection of the first point, and
a spacer which forms a lateral connection between the fixing screw and the support foot, the spacer being secured with the support bar to the base plate by the fixing screw.
15. The timepiece according to claim 14 , wherein the timepiece is a watch.
