Abstract

JEWEL OF THE KIND NECKLACE, BRACELET OR DIADEM OF THE SEMI-RIGID TYPE PRESENTING A CONTINUITY SOLUTION WITHOUT CLOSURE, ALLOWING ITS INSTALLATION BY TEMPORARY SPACING OF BRANCHES, CONSISTING OF A PLURALITY OF ELEMENTS A, B, C, D, THREADED ON A LINK X OF CURVILINE SHAPE AND WITH RESILIENT PROPERTY CHARACTERIZED IN THAT THIS JEWEL IS PARTICULARIZED BY THE FACT THAT IT ALSO INCLUDES MEANS REACHING THE SAID ELEMENTS IN CONNECTION WITH ONE OF THE OTHERS ALLOWING THEIR SIMULTANEOUS ROTATION AROUND THE SAID LINK. THE INVENTION APPLIES TO NECKLACES, BRACELETS OR DIADEMS.

Description

The invention relates to a jewel that can be a necklace, a bracelet

  or a diadem of the semi-rigid type having a solution of continuity, without clasp, that is to say that its installation on the neck or wrist is done by temporarily spacing branches. It is well known to make such a jewel

  means of a plurality of elements (pearls, metal plates)

  tallic) strung on a substantially resilient soul.

  The present invention aims more particularly

a reversible jewel.

  Reversibility is known in the case of

  two-sided clasp, but it was never realized

  in the context of semi-rigid jewelry of the aforementioned type.

  In fact, this reversibility requires a resilient link in the shape of a crescent, the possibility

  for the elements to revolve around the link, and

  yens driving elements through each other cause the near simultaneous rotation of these elements

in relation to this link.

  Other peculiarities and advantages will appear

  reading the description and the claims that

  follow, with reference to the attached drawings in which:

  FIG. 1 is a diagram showing the functions

  positions of a jewel according to the invention - Zesfigures 2 and 3 cross sections of elements-; - Figures 4 and 5 views in elevations of two kinds of elements; - Figure 6 a plan view of a collar - Za Figure 7 an embodiment of fields of elements; - Figure 8 an elevation of a conical collar; - Figure 9 an elevation of a straight cylindrical collar; - Figure 10 a view of a collar in position

unstable.

  As can be seen from these figures, the

  necklace taken here as an example of the application of the invention

  tion comprises a plurality of juxtaposed elements A.B.

  C. D. T strung freely on at least one X-link

  round elements, said elements being moreover provided with means enabling one of these elements to

  drag in its rotation the neighboring element.

  As can be seen in the diagram of FIG. 1, this link X whose stable shape is a portion of a circle (greater than 135 of angle at the center) or assimilated curve may have with respect to an element, for example A, two symmetrical stable positions I (solid line) and III (dashed) with respect to the unstable position II (mixed lines). This unstable intermediate position II is

  obtained by spreading the branches and provoking

  at least one of these elements (and

  two) with respect to this link X. This reversibility effect is made possible by the fact that the elements Z are connected to each other not only by the common link X crossing their channel

  as shown in Figures 2 and 3, but also

  by a drive means outside this channel.

  This drive means can be a second Y link identical to the X link and crossing a channel 2 spaced from the

channel 1 (Fig. 3, 4 and 5).

  As an alternative or complementarily the elements

  Z can have their adjacent fields of complementary shapes

  This is shown in Figures 4 and 6, where we note that the fields of the same element are concave (throat) and convex to form a

assembly of the mouth of a wolf.

  Of course, it is not necessary that the entire length of the field is thus consistent it is sufficient that

part of it, be it.

  If the Z elements do not have complementary fields

  otherwise consistent and therefore unsuitable for

  their mutual training, as for example the elements Z7 of FIG. 7, it is then necessary to have a second link, which acts as a

  means of training, this link then passing through the

nails 2 (Fig. 3).

  It goes without saying that the presence of this second link can be added to the complementarity of fields as is the case of the structures shown in Figures 4 and 6.

  The invention makes it possible to obtain reversible jewels

  conical (Fig. 8) or only cylindrical (Fig. 9)

  (case of choker necklaces or some bracelet).

  Obviously for the first we use elements Z having a trapazoldal elevation (Fig. 4 and Fig. 6) in

  the second, the Z elements are parallel fields (Fig.S).

  It is to be observed that in the case of a necklace,

  the generators of the previous central elements are

  inclined relative to the vertical, since these elements must apply against the upper part of the sternum, and that against they are almost vertical

  at the ends in contact with the neck.

  It follows that such a collar includes elements

  different shapes from the axis of symmetry.

  Central Element A could be strongly

  perzoldal and the extreme elements N with parallel fields all the intermediate elements being less and less

  bias from the center to the ends.

  For simplicity, it is nevertheless possible,

  as shown in FIG. 10, to divide the 1/2 length into 3 or 4 zones each consisting of identical elements, for example a central zone A, a zone B.C.D.E., less

  convergent, a zone F.G.H.I.J.K. even less conver-

  and a zone L to T of elements with parallel fields.

  The invention applies to jewelery of the kind used in

tie - bracelet - tiara.
