Definitions
- the present invention relates to a jeweler ring configured to accommodate on fingers of different sizes. More particularly, the present invention relates to a jewelery ring comprising one or more adjustment plates cooperating with guide means for guiding the displacement of the adjustment plate or plates.
- a jewelery ring comprising a device for accommodating the size of the fingers, in which the device incorporates plates removably mounted radially in the body of the ring, is known.
- US5636531 discloses a ring in the thickness of which is inserted a hoop that can be adjusted with a screw fixed in the body of the ring, or with the aid of a piston system.
- the present invention relates to a jeweler ring configured to accommodate on fingers of different sizes
- a ring body having a substantially annular opening and for receiving the finger, the ring body having at least one housing communicating with the opening; at least one adjustment wafer mounted movably in the housing and extending over an angular segment along the ring body; a spring device configured to exert an elastic force on the adjustment wafer so that the latter can be moved along a substantially radial axis with respect to the ring body, the ring being configurable between a first configuration in which a diameter internal
- the opening of the ring is maximum and substantially equal to the diameter of the inner face of the ring body and at least a second configuration in which the internal diameter of the opening of the ring is reduced and defined, at least in part, by the adjustment plate which protrudes from the inner face of the ring body; the ring comprising a guiding device configured to guide the movement of the wafer
- the spring device is configured to exert the elastic force substantially in the center of the angular segment formed by the adjustment plate.
- the ring of the invention comprises a simple construction guide device, requiring few parts to perform a good guidance and being characterized by small contact surfaces, thereby limiting friction.
- Figure 1 shows a perspective view of a jewelery ring comprising movable pads, according to one embodiment
- Figure 2 shows a top view of the ring, according to one embodiment
- Figure 3 shows a perspective view of the jewelery ring in which details of an adjustment wafer are visible
- Figure 4 illustrates a leaf spring removably mounted on the adjustment wafer, according to one embodiment
- Figure 5 shows the ring comprises a guide device according to one embodiment.
- Figure 1 shows a perspective view and Figure 2 shows a top view of a jeweler ring 1 configured to accommodate on fingers of different sizes, according to one embodiment.
- Figures 1 and 2 show a ring body 10 having a substantially annular opening 16 and intended to receive the finger.
- the ring body 10 comprises three adjustment plates 21 which are preferably arranged along the circumference of the ring body 1, on its inner face 17.
- the arrangement of the three adjustment plates 21 may allow a combined movement of translation and rotation of the ring 1 on the finger, if necessary.
- Each of the adjustment plates 21 extends over an angular segment along the ring body 10.
- the adjustment plate 21 is provided with a contact surface 25 coming into contact with the finger when the ring 1 is worn.
- Each of the adjustment pads 21 is configured to move along a substantially radial axis 11 with respect to the ring body 10 (in FIGS. 1 and 2, this displacement is indicated by the arrow D).
- the opening 16 of the ring 1 has a maximum value substantially equal to the diameter of the inner face 17 of the body of the ring 10 (the surface of the wafer is substantially flush with the face 17), and at least one second configuration in which the internal diameter of the opening 16 of the ring is reduced and defined, at least in part, by the plate
- the adjustment plates 21 make it possible to adapt the internal diameter of the ring 1 to the finger, within the limits of the displacement of the movable plates 21.
- FIG. 3 shows a perspective view of the jewelery ring 1 in which the ring body 10 is shown cut away on the outside so as to display elements of the ring 1 which would otherwise be hidden by the ring body 10
- FIG. 3 shows a housing 12 included in the ring body 10 and in which is mounted one of the adjustment plates 21.
- the ring body 10 comprises three housings 12, in each of which is mounted an adjustment plate 21.
- the housing 12 communicates with the opening 16 on the inner face 17 of the ring body 10.
- Each adjustment plate 21 moves along the axis 11 inside the housing 12 so as to make protrude more or less from the inner face 17, between the first and said at least one second configuration, and thus change the inner diameter of the ring 1.
- Figure 3 also shows a spring device 20 cooperating with the adjustment plate 21 so as to exert an elastic force on the adjustment plate 21 directed along the radial axis 11 towards the center 13 of the ring body 10.
- the spring device comprises a spring blade 20.
- the leaf spring 20 extends over an angular segment along the ring body 10. In the particular example illustrated in FIGS. 3 and 4, the leaf spring 20 extends substantially parallel to the adjustment plate 21.
- FIG. 4 shows an isolated view of an adjustment plate 21 on which the leaf spring 20 is mounted.
- the center of the spring blade 20 is removably mounted on the adjustment plate 21 by crimping means 24.
- the crimping means comprise at least one pair of tabs 24 (or claws) foldable coming to secure the center of the leaf spring 20 on the adjustment plate 21 when the legs 24 are folded.
- the tabs 24 are foldable by elastic deformation.
- All other fastening means of the spring blade 20 to the adjustment plate 21 to the extent that the spring blade 20 is mounted to the adjustment plate 21 removably (or a non-permanent attachment to disassemble the spring without damaging the spring or plate) may be considered.
- the leaf spring 20 can be attached to the adjustment plate 21 by clipping.
- the mounting of the spring blade 20 removably on the adjustment plate 21 rather than welding or other permanent fastening means allows to maintain an unchanged hardness of the blade- 20. In this way, the spring blade 20 retains its elastic properties while ensuring reliable contact and good cooperation between the leaf spring 20 and the adjustment plate 21, with a good distribution of forces.
- the leaf spring 20 is of curved shape having a first inflection zone 31
- the leaf spring 20 exerts the elastic force substantially at the center of the angular segment formed by the adjustment plate 21.
- the leaf spring 20 comprises a second inflection zone 32 at each of the ends of the angular segment formed by the leaf spring 20.
- the second inflection zones 32 are intended to bear against an upper wall 14 of the ring body 10, at the bottom of the housing 12 while remaining free to move radially along the upper wall 14.
- the ring 1 comprises at least one cover 40 configured to be fixed to the ring body 10 so as to retain the adjustment plate 21 in the housing 12. More
- the cap 40 serves as a stop limiting the displacement of the adjustment plate 21 along the radial axis 11 towards the center 13 of the ring body 10.
- the adjustment plate 21 has an overlapping zone 22 at each of its ends. At least a portion of the cover 40 can then bear on the overlap zone 22 when the cap 40 is attached to the ring body 10. When fixing the cap 40 to the ring body 10, at least a portion of the cap 40 can come to bear on the area of overlap 22, so that a portion of the cover 40 acts as the stop limiting the displacement of the adjustment plate 21 along the radial axis 11 towards the center 13 of the ring body 10.
- the adjustment plate 21 may have only one overlapping zone 22 at one of its ends.
- the overlap zone 22 could extend on at least one of the lateral sides 23 of the adjustment plate 21.
- Mounting hoods 40 by screwing allows easy disassembly of the ring body 10, for example to facilitate maintenance operations.
- the covers 40 may be welded, for example by laser, to the ring body 10.
- At least one of the adjustment plate 21, the leaf spring 20, the cap 40 and the body of the ring 10 is manufactured in precious metal, such as the gold or such an alloy. In a preferred way, all these components are made of a precious metal.
- the adjustment device may comprise less than three adjustment plates 21, see more than three adjustment plates 21.
- the adjustment plates 21 extending generally longitudinally in circular arc, so as to be more or less in accordance with the shape of the ring body 10.
- the adjustment plates 21 could have another shape (for example with a flat surface rather than an arc) in to the extent that they can fulfill their role of accommodating fingers of different sizes. These alternative arrangements may also allow a combined movement of translation and rotation of the ring 1 on the finger, if necessary.
- the adjustment plate 21 which moves in the housing 12 of the ring body 10, does not generally come into contact with internal surfaces of the ring body 10, that is to say, except with guiding projections 50 provided on the side walls 15 of the housing 12 as described below with respect to Figure 5. Indeed, the adjustment plate 21 is mechanically connected to the ring body 10 only through 20. The friction that could oppose the elastic force of the spring device 20 and create wear parts are thus minimal.
- the ring 1 comprises a guiding device configured to guide the displacement of the wafer.
- the guiding device comprises at least one notch 51 provided on the adjustment plate 21, the notch 51 cooperating with at least one projection 50 provided in the housing 12.
- the guide device comprises a notch 51 on each of the lateral sides 23 of the adjustment plate 21.
- Each of the notches 51 cooperates with a projection 50 provided on each of the side walls 15 of housing 12.
- the lateral sides 23 and the side walls 15 are in a plane substantially parallel to the plane of the ring 1 (plane of the ring means a plane intersecting the ring in two symmetrical rings, the radial axis 11 of the plate of adjustment 21 lying in this plane).
- the contact surfaces between the notch 51 and the projection 50 are defined, respectively, by the thickness 53 of the lateral sides 23 of the adjustment plate 21 and the thickness 52 of a flank side of the projection 50.
- the friction of the contact surfaces can be minimized by improving the
- Each of the lateral sides 23 of the adjustment plate 21 may comprise more than one notch 51 cooperating with more than one projection 50 provided on each of the side walls 15 of the housing 12.
- the projection 50 can also serve as an abutment, limiting a radial and angular displacement of the adjustment plate 21.
- the shape of the projections 50 and notches 51 can be any shape.
- the guiding device makes it possible to ensure a smooth and safe movement of the movable plate 21 with respect to the ring body 10.
- the guiding device of the invention allows the adjustment plate 21 to move reliably without getting caught in the housing 12.
- An advantage of the guiding device is that it is of simple construction, requiring little parts to perform a good guidance.
- the guiding device is also characterized by small contact surfaces, thus limiting friction.
- a method of assembling the ring 1 may comprise removably mount the spring device 20 on the adjustment plate 21. Once the spring device 20 is mounted on the adjustment plate 21, the latter is positioned in the housing 12. A cover 40 is then attached to the ring body 10 so as to retain the adjustment plate 21 in the housing 12.
- the ring 1 of the invention avoids usual retouching on normal rings and significantly reduces the number of alliances with precious stones to store and available to the customer, because in practice with only four dimensions we can cover a range of diameter for the opening 16.
