The present invention is a bracelet or other
jewel having a plurality of jointed elements ca

another when it is desired to put on or remove
the jewel, this application constituting a division
of application Serial No. 125,955, ?led February
16, 1937 on “Bracelets or other jewels.”
rIhis bracelet has, in the state of rest, the
general shape of a split annular element and the
jointed parts thereof are associated with springs
which, in the position of rest, determine the rela
tive positions of said parts, in such manner as to
ensure that the whole assumes this form of a
15 split annular element. However, it is possible
to pivot the jointed parts of the bracelet with
respect to one another against the action of said
springs, so as to move the ends of the bracelet
away from each other, and thus permit of putting
2 O on or removing said bracelet, which is not possible
- in the case of rigid annular split bracelets.
Such a bracelet can be ?tted exactly to the
size of the wrist or ankle, Without involving any
difficulty for putting on or removing said
In a preferred embodiment of this invention
the hinges are constituted by male and female
surfaces of revolution assembled‘ around a com
mon axis of revolution and flush with the external
30 surface of the bracelet. With such an arrange
ment, it is possible, by carefully working the parts,
to wholly conceal these joints in the position of
rest of the bracelet. If said bracket is too big or
includes ornaments projecting to a considerable
3 5 distance from the outer surface thereof, and if,
consequently, it is difficult to make use of the
arrangement just above set forth, the limited
value of the relative angular displacements of
the contiguous parts will however permit of hiding
4 O the spaces between said parts by means of cover
ing pieces easy to make. Therefore, in all cases,
it is possible to give the bracelet, if so desired,
the aspect of an annular element made of a
single piece.
Other features of the present invention will
result from the following detailed description of
some speci?c embodiments thereof.
Preferred embodiments of the present inven
tion will be hereinafter described with reference
50 to the accompanying drawing, given merely by
way of example, and in which:
Figure 1 is a diagrammatic plan view of a
bracelet made according to the present inven
Figure 2 is an elevational View in which the
showing, re
spectively, two adjacent jointedWe parts
of the 5
Figure 5 is a partial sectional view of the
bracelet in the state of rest;
Figure 6 is an analogous view, the bracelet be
ing deformed so as to permit of putting it on or
of removing it;
Figure 7 is an elevational vi ew, on an enlarged
scale, with parts cut away, of a detail of the pivot
ing connection of two adjacent parts and of the
arrangement of the springs;
Figures 8 and 9 are diagrammatic plan views 15
relating to modi?cations.
As shown by Figures 1 to 7, the bracelet in
cludes a plurality of parts I, 2, 3, 4, 5 pivoted
to one another through axes 6 engaging in
knuckles provided in the common edges of adja~~ 20-“
cent parts. Thus, in the example illustrated by
the drawing, one of the parts or elements of'the
bracelet (Figure 3) includes a central knuckle 1
adapted to fl t in a recess 8 provided in the edge
of the other element (Figure 4) between , two 25
knuckles 9. The two elements connected together
by the insertion of assembling pin 6 into knuckles
‘l and 9 can thus pivot with respect to each other.
The knuckles 9 of one of the elements are re
cessed at Ill transversely to the pivoting axis and 30
corresponding recesses are provided at H in the
other element. In these recesses are engaged
spring blades l2 which have, in the state of rest,
a curvature corresponding to that of the annular
shaped bracelet and which apply against one an- 35
other the inner faces (such as 1a and 8a, Figures
3 and 4) of the ridges of the adjoining elements.
With this arrangement, the various jointed ele
ments occupy, in the state of rest, relative posi
tions such that the bracelet has the appearance 40
of a split annular structure, as shown by Figure 1.
By carefully machining the ridges of the elements,
and possibly by providing a suitable ornamenta
tion of the surface of the bracelet, it is possible
to conceal these ridges.
In order to put on the bracelet or to remove
it, it su?ices to move the end elements I and 5
away from each other, which produces relative
angular displacements of the elements of the
bracelet against the elastic action of the springs. 50
Left to itself, the bracelet returns into its initial
shape. In order to avoid exaggerate relative rota
tions of the elements, which might cause the
springs to break, it is advantageous to provide,
on the ridges of the joints, projections such as 55
l3 (Figure 3) engaging in holes l4 (Figure 4)
the edges of which parallel to the pivot pin form
abutments for projections l3.
In the above described embodiment, the hinge
surfaces are constituted by male and female cyl
inder portions jointed about their common piv
oting axis 6 and tangent to the external surface
of the elements (see Figures 1 and 6), which
facilitates the concealment of the ridges between
10 contiguous elements.
But it may occur that, in the case of very big
bracelets or of bracelets the ornamentation of
which projects to a considerable distance from
the body thereof, this kind of articulation can
15 no longer be employed.
In this case, as shown
by Figure 8, I provide, in the state of rest, angles
15 between the contiguous elements so as to per
mit of their pivoting with respect to one another
despite the eccentric position of the pivoting
20 axes.
However, these angles are the smaller as
the number of articulated elements is greater.
When they are small it is easier to conceal them
by means of covering elements such as I6 (Fig
ure 9) the cheeks 16a of which are pivoted about
25 pins Gor rigid with one of the contiguous ele
ments, whereby the bracelet keeps the ap
pearance of a structure made of a single piece.
If a watch is carried by one of the elements of
the bracelet, the latter constitutes a wrist watch
30 the ?xation of which to the arm is both simple
and original.
Of course, the idea of dividing an annular
structure into a plurality of jointed elements pro
vided with return springs can, according to‘ the
35 present invention, be applied to collars or other
jewels or ornaments.
In a general manner, while I have, in the above
description, disclosed what I deem to be prac
tical and efficient embodiments of the present
invention, it should be well understood that I
do not wish to be limited thereto as there might
be changes made in the arrangement, disposi
tion and form of the parts without departing
from the principle of the present invention as
comprehended within the scope of the appended
Having thus fully described the invention, what
I claim as new and desire to secure by Letters
Patent is:
1. An article of jewelry, and especially a
bracelet, which comprises, in combination, a
series of chambered elements pivotally connected
to one another and having openings in the joints
between them, and leaf springs positioned Within 10
certain of said elements and extending through
the said openings into adjacent elements and
bearing against the walls of the latter to urge
said elements toward their relative positions for
which the whole assumes the general shape of a 15
split annular structure.
2. An article of jewelry, and especially a
bracelet, which comprises, in combination, a
series of chambered elements pivotally connected
to one another about parallel axes so as to form a 20
jointed band with openings in the elements at
the joints, cooperating stops formed on the ad
jacent ends of the respective elements arranged
in such manner that when said respective stops
are in contact, the whole of said elements forms 25
a split annular structure, which'can be opened
by forcing the ends thereof from each other, and
leaf springs positioned within certain elements
and extending through said openings. into adja
cent elements and bearing against the walls of 30
the latter for urging said respective stops against
each other.
3. An article of jewelry according to claim 2
further including covering devices carried by
each of said elements and arranged to bridge the 35
joint formed between the outer parts of said ele
ments when said jewel is in the position of max
imum curvature.
4. An article of jewelry according to claim 2
in which each spring is carried by one element
and acts directly upon the inside surface of the
adjacent element.
