Abstract

A decorative piece includes a support made of a material having no usable plastic deformation in which at least one hollow is arranged. The hollow is filled with a first material forming a substrate in which at least one housing is arranged. The housing is arranged so that at least one aesthetic element is housable therein. The substrate further includes a gripper elastically deforming to retain the aesthetic element in the housing. The gripper further includes at least one setting element. A method for setting an aesthetic element on a support includes taking a support provided with at least one hollow, taking at least one aesthetic element, filling the hollow with a first material, making a setting hole and a gripper in the first material, and setting the aesthetic element by placing it in the hole and by deforming the gripper so as to retain the aesthetic element.

First claim

The invention claimed is:

1. A decorative piece, comprising
a support that is at least part of a timepiece component and that is made of a material that does not have a plastic deformation sufficient to permit setting an aesthetic element directly into the material of the support, and in which at least one hollow is arranged, the at least one hollow being a blind hole in the support, wherein
said at least one hollow is filled with a first material forming a substrate in which at least one housing is arranged,
said at least one housing is arranged so that the aesthetic element is housable therein,
said first material is an amorphous metal alloy having an elastic limit greater than 1500 Mpa,
said substrate further includes a gripper elastically deforming to retain said at least one aesthetic element in said at least one housing, said gripper further including at least one setting element that includes a bead which was heated to a temperature higher than a vitreous transition temperature of the amorphous metal alloy.

2. The decorative piece according to claim 1 , wherein said at least one hollow includes vertical flanks to improve retention of each aesthetic element in the support.

3. The decorative piece according to claim 1 , wherein said at least one hollow includes flanks arranged so that a surface of the hollow increases with a depth of the hollow.

4. The decorative piece according to claim 1 , wherein said at least one hollow includes flanks arranged so that a surface of the hollow decreases with a depth of the hollow.

5. The decorative piece according to claim 1 , wherein the first material includes at least one element which is of a precious type, comprised in the list including gold, platinum, palladium, rhenium, ruthenium, rhodium, silver, iridium or osmium.

6. The decorative piece according to claim 1 , wherein a distance between the aesthetic element and one edge of the hollow is at least 0.01 mm.

7. The decorative piece according to claim 1 , wherein a height of the housing is at least equal to a height of a culet of the aesthetic element.

8. A method of manufacturing a decorative piece, comprising
providing a support that is at least part of a timepiece component and that is made of a material that does not have a plastic deformation sufficient to permit setting an aesthetic element directly into the material of the support,
arranging at least one hollow in the support, the at least one hollow being a blind hole in the support,
filling said at least one hollow with a first material forming a substrate in which at least one housing is arranged, said at least one housing being arranged so that the aesthetic element is housable therein, said first material is an amorphous metal alloy having an elastic limit greater than 1500 Mpa, and
deforming a gripper of said substrate to retain said at least one aesthetic element in said at least one housing, said gripper further including at least one setting element, and said deforming includes heating a bead of the at least one setting element to a temperature higher than a vitreous transition temperature Tg of the amorphous metal alloy.
