PIECE OF JEWELLERY
This invention relates to a piece of jewellery comprising two ring rails
arranged substantially parallel and coaxially to each other, which are interconnected
through at least two bridges, and comprising at least one mounting for a jewel or the
5 like which is held between said ring rails.
Pieces of jewellery of that kind are known from prior art. They are formed
especially as finger rings or bangles and consist of two ring rails which are arranged
substantially in parallel side by side and coaxially to each other. The two ring rails
are connected to each other through at least two, but mostly four bridges in order to
10 obtain sufficient stability of said two juxtaposed ring rails. Between these ring rails
jewels are arranged which are preferably held in a mounting. With these pieces of
jewellery known from the prior art, the mounting can either be rigidly connected to
the ring rails and thus forrn a further bridge or can be freely guided or so as to be
movable between the ring rails upon overcoming frictional forces.
From the prior art there are further known pieces of jewellery consisting of
three ring rails which are also arranged in parallel side by side and coaxially to each
other and are interconnected through at least two bridges. In this case, too, jewels
are arranged between the individual ring rails in corresponding mountings. With
these pre-known pieces of jewellery it is also known to fix at least one bridge to the
ring rails in such a manner as to be detachable in order to remove the mountings held
between the ring rails together with the jewels and replace them by different
mountings carrying jewels.
These pieces of jewellery known in the jewellery market have proven
worthwhile and are available both as finger rings and bangles or the like.
Basing on this prior art, it is an object of the invention to provide a piece ofjewellery of this kind which can be manufactured at low cost and which is variable
to a great extent in order to change the outer appearance of the piece of jewellery at
low technical expenditure.
With a piece of jewellery of the type concerned the solution of this object
provides that the mounting is arranged on a third ring rail detachably provided
between the first two ring rails and corresponding in its diameter substantially to the
diameter of the first two ring rails, and that the axial width of said third ring rail at
,.. . 2121.~3.
least in part-areas thereof corresponds to the spacing of the first two ring rails so that
~ the third ring rail can be clamped between the first two ring rails.:.~ Consequently, with a piece of jewellery formed according to this teaching, the
third ring rail having the mounting and the jewel arranged therein can be clamped
S between said first two ring rails in an advantageous and uncomplicated manner in
order to so provide a piece of jewellery having the appearance of a single piece.
Thus, the piece of jewellery according to the invention represents in its nature two
j, pieces of jewellery that can be worn either jointly or separately from one another.
!`' The required holding strength between the two pieces of jewellery is obtained there
~ 10 by the frictional forces between the ring rails fitted into each other. This also allows
;~ the third ring rail to be removed from the first two ring rails without any considerable
;3 danger of losing one of said ring rails.
- The joining of the third ring rail with the first two ring rails, and its separation
therefrom, is facilitated by the third ring rail having an open construction. With this
embodiment it has proven to be particularly advantageous if the third ring rail consists
.:
of resilient material, preferably of precious metal such as gold, silver, platinum or
the like or alloys thereof. By the resilient properties of the third ring rail its seat in
the first two ring rails is improved, the third ring preferably clamping itself against
, the bridges connecting the first two ring rails.
According to a further aspect of this embodiment of ~e piece of jewellery of
;~ the invention it is provided that the third, open ring rail has two ends provided at a
,~ distance to each other, at least one of which having a mounting for jewels or the like.
~, With this embodiment it is particularly advantageous that between the first two ring
rails a mounting having a jewel can be arranged which at the same tirne can serve as
an additional connecting bridge and which is flanked by the two ends of the third
open ring rail. A piece of jewellery formed in this way has the advantage that at least
one mounting for a jewel or the lilce is fLxed on both the first two ring rails and the
third ring rail, allowing both the third ring rail to be worn as an individua1 piece of
jewellery and the first two ring rails to be worn as an individual piece of jewellery
with a jewel.
According to a fur~er development of this embodiment it is provided that both
ends of the third, open ring rail carry a mounting wherein one or more jewels or the
212~ -33~
. like can be fixed.
A further possibility of variation of the piece of jewellery according to the
invention is obtained in a simple constructional manner in that between the two ends
of the open third ring rail a mounting is arranged which is held between the first two
5 ring rails and/or is guided to be freely movable or to be movable upon overcoming
frictional forces. With this embodiment, the mounting provided between the first two
ring rails can be removed after removal of the open third ring rail. Accordingly,
jewels either of different shape, different colour or also different size can beexchangeably arranged between the first two ring rails. The open third rail, after its
10 insertion into the first two ring rails, prevents the mountings arranged between the
first two ring rails from being lost. Instead of the mountings equipped with jewels,
i~ also precious metal plates can be arranged between the first two ring rails, the plates
i~ being provided, for example, with different signs of the zodiac.Improved fixing of the third ring rail between the first two ring rails is
15 obtained in a simple way in that the third ring rail has recesses on its outer surface
corresponding to the bridges between the first two ring rails. When inserting the
third ring rail between the first two ring rails, the third ring rail snaps with its
recesses over the bridges. In addition to an even outer appearance of the surface of
the three ring rails, also a form-fit connection between the first two ring rails and the
20 third ring rail is thereby obtained.
According to a further development of the piece of jewellery of the invention
it is provided that the bridges are formed as mountings for jewels or the like. It has
proven to be particularly advantageous to dispose the bridges diametrically oppositely
in order to obtain sufficient stability also with a piece of jewellery having only two
25 connecting bridges.
. Variability of the piece of jewellery according to the invention is further
increased by the third ring rail consisting of a material different from the material of
the first two ring rails. It is possible, for example, to make the first two ring rails
of yellow or red gold and the third ring rail of white gold. However, also other. 30 combinations of materials are conceivable. Thereby, especially the value of the piece
of jewellery can be adapted to the customer's ideas.
- Finally, according to a further feature, it is provided that the piece of
.. - . .i-i, : .. . ~: ~ ~ - . ~

jewellery is formed either as a finger ring or a bangle.
More particularly, this invention provides, a piece of jewellery comprising
ring rails arranged substantially in parallel and coaxially to each other as well as
connected to each other and comprising a mounting between said ring rails, the
5 mounting together with a third, detachable ring rail being held between said two ring
rails, the diameter of the third ring rail substantially corresponding to the diameter
of the first two ring rails, and the axial width of the third ring rail corresponding at
least in part-areas to the spacing of the first two ring rails so that the third ring rail
can be clamped between the first two ring rails, characterized in that the third ring
10 rail is formed to be open and that between the two ends of said open third ring rail
the mounting provided between the first two ring rails is detachably arranged.
Further details and advantages will become apparent from the following
description along with the accompanying drawings representing a preferred
embodiment of the piece of jewellery according to the invention wherein there is15 shown in:
Figure 1 a piece of jewellery formed as a finger ring in a plan view;
Figure 2 a first part of the piece of jewellery according to Figure 1 in a
side view;
Figure 3 a mounting with a jewel inserted therein in a side view,Figure 4 a second part of the piece of jewellery according to Figure 1 in
a side view;
Figure 5 a sectional side view of the part according to Figure 2
following line V-V in Figure 2.
A piece of jewellery formed as a finger ring 1 consists of two ring rails 2, 3
25 arranged in parallel side by side and coaxially to each other and interconnected
through two bridges 4 (Figure 2) and a plate S which is bent corresponding to the
radius of the ring rails 2, 3. The two ring rails 2, 3, the bridges 4 and the plate S
consist of a precious metal like gold, silver or platinum.
Between the ring rails 2, 3 a mounting 6 is provided carrying a jPwel 7. The
30 mounting 6 is fixed to a third ring rail 8 which is detachably arranged between the
first two ring rails 2, 3 and has a diameter substantially corresponding to the diameter
of the first two ring rails 2, 3 and an axial width corresponding to the spacing of the
~ , -. -: ~ ., :

s
adjacent first two ring rails 2, 3 so that the third ring rail can be clamped between
said first two ring rails 2, 3. The ring rail 8, which is shown in detail in Figure 4,
,`~ is of open construction and also consists of precious metal. Besides the mounting 6
carrying the jewel 7 there is fixed a further mounting 9 carrying a further jewel 10.
5 The mountings 6 and 9 are arranged on the two ends of the open third ring rail 8 and
define the opening 11 of the ring rail.
:'; Between the two mountings 6 and 9 respectively arranged on the two ends of
,1 the open third ring rail 8 there is arranged a mounting 12 carrying a further jewel 13,
!'3 which mounting is guided to be freely movable between the first two ring rails 2, 3.
10 To this end both ring rails 2, 3 are each provided with a guide rail 14, respectively
fixed to the mutually facing inner sides of the ring rails 2, 3. Like plate 5, these
guide rails 14 are in the form of a circular arc section corresponding to the curvature
of the ring rails 2, 3.
The mounting 12 is substantially cylindrically formed and has oppositely
15 arranged grooves 15 in its cylindrical wall which receive the guide rails 14 in such
a way that the mounting 12 is movably guided along the g.lide rails between the ~ïrst
two ring rails 2, 3.
Both mountings 6 and 9 of the third ring rail 8 are arranged such as to prevent
the mounting 12 from slipping off the guide rails. Accordingly, the mountings 6 and
20 9 represent locking means.
As may be seen especially from Figure 4, the third ring rail 8 has on its outer
surface 16 recesses 17 corresponding to the bridges 4 interconnecting the ring rails
2, 3. As an alternate to the illustrated configuration, the bridges 4 may be arranged
diametrically oppositely between the ring rails 2, 3, with the recesses 17
25 correspondingly arranged diametrically oppositely in the ring rail 8. At the insertion
. of the ring rail 8 between the first two ring rails 2, 3 the bridges 4 are caught in the
recesses 17. To this end the ring rail 8 is formed to be resilient to a lirnited extent,
whereby a high degree of safety is obtained for the ring rail 8 against falling out from
the ring rails 2, 3.
In the embodiments shown in Figures 1 through 5, the bridges are formed as
, 1
-~ simple elements of a substantially rectangular cross section. However, it is also
- conceivable that the bridges 4 be shaped as mountings into which corresponding
., .

jewels can be inserted.
The invention is not limited to the embodiment shown as a fimger ring. It is
also possible to form a piece of jewellery according to the invention as a bangle.
Furthermore, the invention is not limited to particular precious metals. The
5 scope of variation of the piece of jewellery according to the invention is rather
increased by the use of different materials for the ring rai1s 2, 3 and the ring rail 8.
For example, the ring rails 2, 3 can consist of red gold and the ring rail 8 of white
gold in order to form a piece of jewellery in the so-called bi-coloured style. Finally,
the arrangement of the bridges 4 between the ring rails 2, 3 may deviate from the
10 embtdhme~l shown without departing from ~c scope of protection of dhe invention.
