Abstract
A jewelry rope chain having links interwoven together to form a double helix configuration. Each link has a cross section with the largest transverse distance across the cross section defining a first dimension. Each link has a interior space and a gap along the periphery of the length. The widest dimension of the interior space in a direction consistent with the direction of the gap has a dimension which is less than three times the first dimension. Thus, ratios of approximately 2:1 can be achieved.
Claims21
A jewelry rope chain, having links interwoven together to form a double helix configuration, each link having a cross section, the largest transverse distance across said cross section having a dimension dw, each link having an outer periphery and an inner periphery, and a gap extending at one location between the outer and inner peripheries, the inner periphery defining an interior space, the widest dimension of the interior space in a direction consistent with the direction of the gap having a dimension D, and wherein D is less than three times dw.
A Jewelry rope chain as in claim, wherein said rope chain is formed by pluralities of assemblies of said links in series, each assembly comprising two adjacent links, and an end link enveloping said two adjacent links throughout such chain, said two adjacent links having their respective gaps assembled in the same orientation and being fixedly attached to each other to form a group, and said group being fixedly attached to said end link having a gap orientation about 180 degrees removed with respect to the gaps of the links of said group.
A method of forming a jewelry rope chain having links interwoven together to form a double helix configuration, each link having a cross section, the largest transverse distance across said cross section having a dimension dw, each link having an outer periphery and an inner periphery, the inner periphery defining an interior space, and a gap extending at one location between the outer and inner periphery, the widest dimension of the interior space in the direction consistent with the direction of the gap having a dimension D, where D is less than three times dw, the method comprising the steps of forming a plurality of link assemblies in series, with each assembly comprising two adjacent links and an end link enveloping the other two adjacent links.
