Non-twisting and non-flipping necklace
Twisting and flipping of a necklace along its length may be prevented by restricting the articulation of the links. By providing one section with links that permit articulation only in a vertical direction and another section with links that permit articulation only in a horizontal direction, flipping and twisting can be prevented.
This invention relates to necklaces, including those carrying decorative gemstones. In some arrangements, the necklace is a series of links having settings for the gemstones. Along the length of the chain, as it traverses around the wearer's neck, the links need to be oriented such that the gemstones face outwardly, i.e., away from the wearer. Should a portion of the necklace flip or twist, the gemstones in that portion will then be facing either towards the wearer's skin or perhaps at an angle (e.g., 90°).
Conventionally, the design of the links do little to prevent the necklace from flipping or twisting. However, by providing a combination of links, where some of the links enable articulation in one direction (or, in one plane) with respect to the length of the chain while others enable articulation in another direction at some angle with respect to articulation of the prior links (or, another plane), flipping and twisting can be prevented. In one implementation, the articulation of one set of links is restricted to the vertical plane, i.e., up and down with respect to the links, and the articulation of another set of links is restricted to the horizontal plane, i.e., side to side with respect to the links.
BRIEF DESCRIPTION OF THE DRAWINGS
One type of link 20, illustrated in
Another type of link 30, illustrated in
Additionally, the necklace 10 may also contain interconnecting links 40 and 50, shown in
The first interconnecting link 40 is shown in a segment of three links—a vertically or up-and-down articulating link 20 followed by the first interconnecting link 40 and then a horizontally or side-to-side articulating link 30, separately in
The second interconnecting link 50 is similarly shown in a segment of three links—a horizontally or side-to-side articulating link 30 followed by the second interconnecting link 50 and then a vertically or up-and-down articulating link 20, separately in
In its most basic form, the necklace 10 will comprise a number of vertically (or up-and-down) articulating links 20 and a number of horizontally (or side-to-side) articulating links 30. Where the necklace 10 lays against the neck, the vertically or up-and-down articulating links 20 permit the necklace 10 to follow the contour of the neck. Below the neck, the necklace 10 should lay flat against the wearer's chest, which is achieved by utilizing horizontally or side-to-side articulating links 30. Because any given coupling of links 20 or 30 will allow articulation in only one manner, either in an up-and-down or a side-to-side fashion, the necklace 10 will resist flipping or twisting.
The actual number of each type (links 20 and links 30) depends in part on the length of the necklace 10 and the circumference of the wearer's neck. An equal number of each (links 20 and links 30) will work satisfactorily but a different ratio of links 20 and 30 could be employed as suits the application, for example, in a lengthy necklace where a substantial portion of the necklace 10 lays against the chest as opposed to against the neck of the wearer.
The necklace 10 is shown again in
In the figures, the links are shown in various sizes, alternating between large and small. One may use different size links to accommodate different sizes of gemstones or, should the gemstones all be equal in size, then the links may also be of equal dimensions.
In lieu of using the first and second interconnecting links 40 and 50 to interconnect the vertically articulating links 20 to the horizontally articulating links 30, a coupling device consisting of a hinge element that enables horizontal or side-to-side articulation and a second hinge element that enables vertical or up-and-down articulation would be sufficient to interconnect the links of differing articulation, without the need to accommodate a gemstone. Further, the other links of the necklace 10 could also assume a different form and not carry gemstones, i.e., all metal.
