Definitions
- the present invention relates to an ornamental chain element composed of successive elements having a general shape, for example spherical of the same dimensions or of different dimensions and made of metal, preferably precious, for example gold.
- the applicant company described in FR-A-2 779 921 an ornamental chain composed of successive elements, characterized in that at least one of the elements of the chain comprises a hollow body inside which an insert is fixed. shaped to retain a connecting member connected to an adjacent element of the chain, the insert being constituted by at least one split sleeve, the shape of this sleeve being wide enough to allow passage of the body of the connecting member.
- the present invention proposes to produce an ornamental chain element allowing an assembly process even faster than for the elements of the chain of the previous document and better resistance of the assembled elements in particular during an attempt to tear off.
- the chain element according to the invention is essentially characterized by the fact that it comprises a hollow body consisting of two complementary parts provided with cooperating internal snap-fastening means, the hollow body being shaped to retain at least one connecting member to an adjacent element of the chain and internally comprising a member for locking the latching means in their assembled position.
- the latching means of the two parts of the hollow body advantageously comprise tabs projecting from one of the parts of the hollow body, each provided with a beak-shaped end capable of engaging on a coupling surface performed in the other part of the hollow body.
- This other part may advantageously include a recess in which is housed a tubular blocking member arranged and shaped to press outward the ends of said tabs and thus block them in the assembled position.
- the blocking member can be made of the same material as the hollow body and causes during assembly a deformation of the end of the tongues and in a way a riveting of the tongues on their bearing surface.
- the two parts of the hollow body according to the invention have in their outer wall cutouts for the establishment of the connecting members and their retention in the hollow body after assembly of the two constituent parts thereof.
- the invention allows a wide variety of embodiments of hollow bodies, which can advantageously be spherical, made by bar turning and capable of receiving a precious stone set in a blind bore made in one of the parts of the hollow body.
- the link member can, as in the previous document of the applicant company mentioned above, be constituted by a two-headed pin.
- FIG. 1 is a top view of an element of ornamental chain according to the invention, provided with three connecting members to adjacent elements
- Figure 2 is a sectional view along II-II of Figure 1
- Figure 3 is a sectional view along III-III of Figure 1
- - Figure 4 is an enlarged view of detail A of Figure 2
- Figure 5 is an exploded view corresponding to Figure 2, showing the components of the element according to the invention before their assembly. Illustrated in the drawing is an exemplary embodiment of an element according to the invention, of spherical shape, generally designated by 1 and in which a precious stone 2 is set, the element being able to be made of gold or other precious metal.
- the element according to the invention is a hollow body produced by assembling two parts 3 and 4 each having a spherical external profile, the two parts 3 and 4 a once assembled making element 1 of generally spherical shape.
- the elements 3 and 4 include cooperating snap-lock means.
- These means comprise tongues 5, three in number in the example illustrated, projecting from part 3, equiangularly distributed, these tongues 5 being each provided with a beak-shaped end 6.
- part 4 of element 1 complementary to part 3 thereof, comprises a succession of cylindrical cavities of different diameters 7, 8, 9 and a blind bore 10 of partially frustoconical shape for reception by setting the precious stone 2.
- the cavity 7 is dimensioned to allow the guiding and the reception of the tongues 5 of the element 3, the recessed bearing surface 11 between the cavities 7 and 8 constituting the bearing beyond which, as best seen on the FIG. 4, the beak-shaped end 6 of each tongue 5 snaps in when this end is received in the cavity 8.
- the cavity 8 is extended by a cavity 9 of smaller diameter in which can be accommodated, with a tight fit, a ring 12 provided with a chamfered end 13.
- the ring 12 is housed in the cavity 9 by projecting through its chamfered end 13 in the cavity 8 in which the beak-shaped end 6 of each of the tongues is to be housed 5.
- This riveting effect at the ends of the tongues ensures mechanical strength of the two constituent parts of the chain element according to the invention, offering excellent resistance to an attempt to tear off.
- the element according to the invention is capable of receiving cylindrical pins 14 each provided with two biconical heads 15.
- the parts 3 and 4 of the chain element according to the invention have recesses 16, and respectively 17, aligned in the assembly position, and in which the pins 14 are engaged which are retained in the internal cavity of the element with numerous possibilities of movement while being prevented from leaving the cavity.
