ABSTRACT:
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not Applicable.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a bracelet with articulated links comprising longitudinally offset elements which interpenetrate one another, connected by pivot members, designed to engage in transversely aligned housings formed through said interpenetrating elements.
2. Description of the Prior Art
DE-A-36 03 850 has already proposed the connecting of articulated links of a bracelet of the aforementioned type by articulation pegs housed partially in the housing of the longitudinally projecting part of one link and pushed out of this housing by a spring, thus engaging the articulation peg in an adjacent housing that opens into the adjacent faces of two offset lateral parts of the adjacent link, which are located one on each side of said longitudinally projecting part. These pegs slide freely in their housing and can be ejected therefrom by the force exerted by the spring so that an arrangement such as this makes the links tricky to fix together because there is a risk that the pivot pegs will be thrown out while they are engaging in the nearby housing of the adjacent link.
U.S. Pat. Nos. 2,518,163 and 1,751,792 have also proposed invisible articulations between links, but these relate, one of them, to hollow two-part links assembled after the introduction of the pivot pin which is thus trapped, and the other, to a link obtained by bending a sheet of metal, two tabs being bent around the pivot pin. In neither instance are the links machined from solid.
BRIEF SUMMARY OF THE INVENTION
In the preferred embodiment of the bracelet of the present invention, each link of the bracelet has a first face and a second face, first and second lateral parts, and a central part which is offset in the longitudinal direction of the bracelet. The offset central part of each link receives the offset central part of the next link adjacently disposed thereto. Each link includes a pair of three housings or apertures. The first pair of housings are oriented substantially transverse to the longitudinal direction of the bracelet and open onto the second face of the offset central part. The second pair of housings are oriented substantially transverse to the longitudinal direction of the bracelet and open onto the first face of the offset central part. The third pair of housings are in communication with the pair of first housings and are oriented substantially in the longitudinal direction of the bracelet and open onto the first face of the offset central part. The links are pivotally connected with a pivot peg having a conical first end and a second end. The first end of the pivot peg is received in the first housings and at least partially projects into third housing. The second end of the pivot peg is received in the corresponding second housing of the adjacently disposed link. A push peg having a conical end is received in the third housing, whereby when the push peg is pushed into the third housing the conical end of the push peg contacts the conical end of the pivot peg and forces the pivot peg transversely outward into the corresponding second housing in the adjacently disposed link. When the push peg is pushed into its locked position within the third housing, the conical end of the pivot peg abuts the side of the push peg thus locking the pivot peg in position.
The object of the present invention is to allow the articulating of links which are easy to manufacture and to assemble. The bracelet thus obtained may be compact and thin and have an attractive esthetic appearance.
This objective is achieved by virtue of the subject of the invention as defined by the claims.
