Problems solved by technology

[0015] This solution seems suitable for solving the problem of increasing the elasticity of the chain, but due to the higher cost of the equipment required to manufacture the frusto-conical springs with reduced dimensions typical of springs for jewelry and the appearance of the helical shape Both the fact that it is necessary to center the spring relative to the element between which it is housed and the problem of keeping the spring in place while the chain is in use by the user, this solution has proven difficult to implement

Embodiment Construction

[0044] refer to figure 1 , figure 1 Showing a part of the chain of the present invention, the whole of which is indicated by 1, it can be observed that the chain comprises successive links and in Figure 6 Multiple cage elements 2 are also visible in the isometric view shown in .

[0045] For clarity, always refer to Figure 6 , it can be observed that each of the cage elements 2 comprises a central body 3 from which separates more than one side arm 4 , the free ends 5 of which side walls 4 are bent towards the base and are magnified Section 5a terminates.

[0046] Each side arm 4 is inserted in a sliding manner into another cage element 2 adjacent to a first cage element 2 .

[0047] The free end 5 of each cage element 2 rests on the surface of the central body 3 when the chain is complete and in the state of maximum extension.

[0048] according to Figure 6 In the example of embodiment shown in , the central body is oval in shape, but said central body could just as w...

Abstract

An extensible chain includes a plurality of cage-shaped elements (2) connected to one another in succession, each one of which includes a flat central body (3) from which two or more lateral arms (4) branch off whose free ends are slidingly inserted in an adjacent cage-shaped element. The adjacent elements define an intermediate space in which there is a spring (6) obtained from a plane metal sheet element from which two tabs (6b) depart that are opposite each other with respect to the base of the metal sheet element and are positioned above it at a distance (H) that, when the spring is at rest, exceeds the distance between the free ends of the lateral arms (4) of any cage-shaped element and the central body (3) of the adjacent cage-shaped element.

Description

technical field [0001] The present invention relates to an extendable chain particularly suitable for making decorative items for wearing, such as for example bracelets, necklaces or similar objects. [0002] The invention also relates to a decorative item comprising the above-mentioned extendable chain. Background technique [0003] As is known, there are various types of necklaces, bracelets and other similar decorative objects comprising a plurality of elements connected one after the other to form a chain. [0004] According to one of said known embodiments, the chain comprises a plurality of cage elements connected in succession, each of which consists of a central body, from which the Two or more lateral bodies are provided, the free ends of the two or more lateral bodies face the corresponding central body, and the two or more lateral bodies are arranged to face each other and inserted into into adjacent cage elements. [0005] The lateral bodies laterally bound th...
