Multi-Track Articulating Necklace

This application claims the benefit of and priority to U.S. Provisional Application No. 63/652,604, filed May 28, 2024, the entire contents of which is incorporated by reference herein.

A necklace is formed with left, center, and right tracks of meshed tiles or “tile segments.” In one embodiment, the tiles are hexagonal and the pattern of meshed tiles resembles a honeycomb. Each left tile is paired with a right tile, with two transverse linking bars connecting the left and right tiles. One of the linking bars connects upper sections of the left and right tiles, and passes through a transverse through hole (which may comprise multiple aligned holes if the center tiles are not solid) in a lower section of a center tile. The other of the linking bars connects lower sections of the same left and right tiles, and passes through a similar through hole in an upper section of a second center tile. This pattern continues along the necklace.

The through holes in the center tiles are larger than the linking bars that pass through them, at least in the direction that is in the plane of the tile. This allows the center tiles a limited amount of rotation with respect to each linking bar, in the plane of the tiles, sufficient to articulate the necklace into a loop. The center tiles may also have an unconstrained ability to pivot about the longitudinal direction of a linking bar, or this ability can be constrained to a given degree by use of non-circular linking bar profiles with a major axis larger than a height of the through holes.

In another aspect, a clasp mechanism of the necklace is formed with the general appearance of the meshed tiles. One side of the clasp mechanism has a center tile with a receiver for a spring clasp. The other side of the clasp has a spring clasp adapted to latch into the receiver, with one side of the spring clasp fixed to a center tile and the other side of the spring clasp fixed to a side tile. The necklace is unlatched by pressing the center and side tiles towards each other to compress the spring clasp.

The foregoing general description of the illustrative implementations and the following detailed description thereof are merely exemplary aspects of the teachings of this disclosure and are not restrictive.

The description set forth below in connection with the appended drawings is intended to be a description of various, illustrative embodiments of the disclosed subject matter. Specific features and functionalities are described in connection with each illustrative embodiment; however, it will be apparent to those skilled in the art that the disclosed embodiments may be practiced without each of those specific features and functionalities.

illustrates, in front plan view, a first necklace embodimentarticulated into a loop.shows, in front plan view, necklace embodimentarticulated into a straight configuration, after disconnecting a receiver sideof a clasp mechanism from a spring latch sideof the clasp mechanism. Necklace embodimentis constructed of left tile segments, center tile segments, and right tile segments, in this case shaped uniformly as hexagonal tile segments meshed in a beehive pattern. Some of the center tile segments are shown with gemstones mounted therein. Although the gemstones themselves are decorative, and a given embodiment need not have them, the particular inventive way in which tiles are joined allows for fairly low-profile tile designs with room for mounting gemstones that are not blocked from the rear.

shows, in a front plan view, a sectionof the/embodimentarticulated into a straight configuration, and including transverse linking bars that secure the tiles together. Sectionconsists of right tile segments, center tile segments, and left tile segments, interconnected by transverse linking bars-. Center tile segments-have an optional, central open section for holding a gemstone.

Each left tile segment pairs with a right tile segment, e.g.,andare paired. Tile segmentsandare connected by transverse linking barsand. The connection may be rigid, i.e, each linking bar may be soldered to each left and right tile segment. Alternately, the left and right tile segments may capture the ends of the linking bars without a rigid connection, e.g., by flaring an end of a linking bar after insertion into a tile segment. In some embodiments, the linking bars may attach to a tile segment without passing completely into it as shown.

Each pair of left and right tile segments meshes with two adjacent center tiles, e.g., tile pair,meshes with center tiles,. The assembly is held together by linking barsand, where center tileis captured between tilesandby linking barand center tileis captured between tilesandby linking bar. This pattern repeats, i.e., a third linking baralso captures center tile, but between tilesand, which are connected by third linking barand also by a fourth linking bar, which in turn captures center tile

Each linking bar passes through a transverse through hole in a center tile. In, the center tiles are not solid at the locations of each through hole, thus the transverse through hole resembles two aligned through holes in opposing sides of the center tile. Nevertheless, the effect is the same as the portions of the through holes that limit angular articulation are at the opposing sides, and such a design is considered “a through hole.”

The particular way in which the linking bars capture the center tiles via the through holes allows a design range of rotation of each center tile with respect to each linking bar, as viewed normal to the face/front of the tiles. Such an articulation is shown in, where tile sectionhas been articulated into an arc turning down and to the right. Note that in, the sides of the through holes are contacting the sides of the linking bars, preventing further angular articulation of the center tiles.

The design range of rotation can be based on the number of tiles in the embodiment. For instance, withcenter tiles, plus/minus 2 degrees of rotation of a center tile with respect to each linking bar allows the assembly to arc completely into a circle. Plus/minus 3 degrees would allow such an embodiment to be worn in more of an oval shape, with some center tiles arcing more than other center tiles.

depict, respectively, back and front perspective views of part of thesection, with jewelsandmounted respectively in center tilesand. It can be appreciated, particularly from the back perspective view, that each center tile can also rotate about each linking bar that captures it, about the longitudinal axis of that linking bar. This allows for a second degree of motion of the necklace assembly, allowing the necklace to fall naturally around a wearer's neck and/or shoulders when worn. An alternative embodiment is further comprised of a third, twisting degree of motion along the necklace, depending on the up/down fit of the linking bars in the center tiles. The overall effect can be one of an undulating surface that conforms to the wearer.

illustrate respectively in top plan, top perspective, side elevation, and end elevation views, a center tileof an embodiment. A mounted jewelis shown in the top plan view of, but is removed from the other views to better show the shape of center tile. One salient feature is a jewel mounting cavitythat passes between a front and a back side of tile. The cavity contains a beveled ledge that assists in holding a jewel in a proper position.

Below the beveled ledge, at a distance that prevents interference with a mounted jewel in cavity, two transverse through holes,pass through the sides of the tile. Particularly from the side elevation of, it can be appreciated that through holesandare oblong. When a linking bar has a round cross section, those skilled in the art will appreciate how the oblong shape ofandallow tileto rotate, as viewed from theview, with respect to each linking bar that captures that center tile.

Although not shown, each linking bar can also be oblong or rectangular in cross section instead of round, with a major dimension that prevents unlimited rotation of the center tile about the longitudinal axis of the linking bar. Those skilled in the art will appreciate that various profiles of either the linking bars and/or the through holes may be designed to achieve a desired range of articulation in each of multiple degrees of freedom.

In one embodiment, the tiles are assembled by placing two linking bars in adjacent through holes of two adjacent center tiles, and then inserting the ends of the two linking bars into two side tiles and securing the linking bars to the side tiles. The “chain” is continued by placing another linking bar in the second through hole of one of the first two center tiles, and a fourth linking bar in an adjacent through hole of a third center tile, and then securing the third and fourth linking bars to a second pair of side tiles. This operation is repeated until a desired overall length is achieved.

Some embodiments may have an overall length such that no clasp mechanism is required, and it can just be lowered over the head. Other embodiments may have a clasp mechanism. A particular preferred clasp mechanism is shown in, and will now be described.

show respectively in top perspective and end elevation views, a receiver sideof a clasp mechanism. Clasp receiver sideappears from the top as four tiles—a left tile, a back center tile, a right tile, and a front center tile. The four tiles, however, are a monolithic piece with scribe lines to make them appear as four tiles. In the end face of tile, a receiver apertureis formed to accept a spring lock. In the bottom of tile, a safety catch plateis formed. Both will be explained further upon description of additional parts of the clasp mechanism.

shows, in top plan view, a spring lock sideof the clasp mechanism. Clasp spring lock sideappears from the top (when assembled), as three tiles-a right tile, a center tile, and a left tile. In reality, tilesandare rigidly connected, and tilesandconnect to two arms of a spring lockdesigned to engage with receiver apertureof receiver side.

shows, in perspective view, a clasp safety armof the clasp mechanism. Clasp safety armconsists of an extended armwith two hinge barrels,on a top side at one end of armand a catchprotruding on the top side near an opposite end of arm.

shows, in back perspective view, an exploded view of a clasp mechanism comprising parts,, and. Although most features present in this view have already been described, hinge features,, andare visible in this view on the underside of tile. A hinge barrelis located between two hinge end platesand, all three features having aligned bores, which also align after assembly with a bore in hinge barrels,of clasp safety arm.

shows, in back perspective view, an assembled and latched view of the clasp mechanism shown in. Spring lock(hidden lines) is inserted and locked into the receiver aperture (/B) of receiver side, specifically tilesand. The clasp safety arm hinge barrelsare attached to the hinge features on the underside of tileby a hinge pin (not visible), allowing armto swing against the underside of tileand secure catch against feature.

To unlatch the clasp of, one first lifts armto disengage it from feature. One then pushes side tilesandtowards each other, which compresses spring lockto allow it to disengage and be pulled away from tile

Although not shown, tileandeach have a through hole similar to those already described for “standard” center tiles, allowing them to be captured between “standard” side tiles by linking bars, such that the clasp mechanism is joined to the remainder of a necklace.

One embodiment has been described with uniform, hexagonal tiles. In an alternative embodiment, the center tiles could be hexagons and the side tiles could be trapezoids or otherwise truncated hexagons, creating a uniform edge of the necklace. In an alternative embodiment, at least some of the tiles are polygons. In alternative embodiment at least some of the tiles are octagons. In an alternative embodiment, at least some of the tiles are circles. In an alternative embodiment, the center tiles could be diamonds and left and right tiles could be triangles. In one embodiment, tile shapes are selected based on aesthetics with alternative shapes providing differing appearances. In an alternative embodiment, tile shapes are selected based on functionality, provide differing arrangements for linking bars, affecting the manufacturing process as well as the articulation. Alternative embodiments will be apparent to those skilled in the art upon reading this disclosure.
