## Background
PRIORITY DETAILS
The present application claims priority from provisional application No. 2018902538, filed in Australia on 13 Jul. 2018, the entirety of which is incorporated herein by reference.
TECHNICAL FIELD
The present invention relates generally to the field of jewellery and in particular to rings worn upon a person's finger. More particularly, the present invention relates to providing a means of preventing a finger-worn ring from rotating about a finger and/or from sliding off of the finger.
BACKGROUND
Rings worn on the finger are known to be susceptible to rotation and slippage, particularly if the ring is slightly too large for the finger it is worn upon. A ring that is slightly too large is sometimes necessary however, particularly for people who have knuckles that are substantially wider than their fingers, for example people suffering from arthritis.
Prior art means of ring tightening and preventing slippage and/or rotation are known, but these are either temporary solutions, or are devices that extend partway around the side of the ring, which are visible and thereby fail to be discreet. Other prior art means are known, such as ring sizing beads. However these involve soldering on small beads of metal to the inside of the ring, which requires an expert jeweller to insert and solder into position and provide no cushioning or ‘give’, and so may be uncomfortable to wear. Furthermore, ring sizing beads are a semi-permanent solution and can be difficult to adjust or remove without damaging the finger ring.
It would therefore be desirable to provide a means of preventing a ring from rotating out of alignment or from slipping off of a finger upon which it is worn.
DISCLOSURE OF THE INVENTION

DEFINITIONS
As used herein, the term ‘finger-ring’ is to be interpreted as an item of jewellery that is designed to be worn upon a finger or toe, and may be more commonly referred to as simply a ‘ring’. A finger-ring typically comprises a loop of material (often one or more metals) through which a finger or toe is passed, so that the ring encircles the finger or toe. The loop is typically referred to as a ‘band’. The ring may further include decorative features such as a setting (with one or more stones), engravings, side stones and other features.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Generally, in a first aspect the invention concerns a pad to be applied to at least a portion of an inner surface of a finger-ring, hereinafter referred to generically as a ‘ring’. In at least one broad embodiment, the pad comprises an elastically compressible pad body that is adapted to compress when a force is applied thereto.
With reference to FIGS. 1A & 1B, depicted is a ring 100 having a setting 102 and an inner surface 104. A pad 110 is attached to the inner surface 104. In an embodiment, the pad 110 generally comprises a compressible pad 110 body and an adhesive layer. The pad 110 body is typically comprised of an elastically deformable and compressible material, whereupon application of a force, the pad 110 body will compress, and upon removal of the applied force the pad 110 body will revert to its original shape. A pad 110 comprising an elastically deformable material in the pad 110 body will therefore, in at least one embodiment, provide a measure of cushioning to any object that presses upon the pad 110.
Without limiting the scope of the invention through theory, it is considered that the pad 110 of at least an embodiment of the present invention provides a significant advantage over prior art ring tightening means such as prior art ring inserts. In at least the present embodiment, the pad 110 is configured to compress and expand as a finger is inserted into or removed from a ring, and it is considered that the compressibility of the pad 110 improves both the life of the pad 110 and the contact between the pad 110 and an inserted finger. In contrast, prior art ring inserts typically flex, which may induce shear forces across any adhesive layers, thereby potentially reducing the lifespan. Flexed ring inserts also tend to be uncomfortable to the person wearing 100 the ring, as there may be the sensation of the ring not sitting ‘square’, or of the flexed insert ‘dragging’ on the skin of the finger.
In one embodiment, the pad body 112 is comprised of one or more polysiloxanes. The polysiloxanes may be in the form of one or more of silicone rubber, silicone resin, silicone foam and silicone sponge. Without limiting the scope of the invention, polysiloxanes are considered to be a particularly advantageous material for the pad body 112 due to their desirable properties. Polysiloxanes are typically both chemically and thermally stable and are also non-toxic, as well as resistant to corrosion and damage from exposure to air and light. Polysiloxanes are also non-supportive of microbial growth and are highly resistant to and repellent of water, enabling a pad 110 of the present invention to be easily and readily cleaned and hygienically maintained.
Embodiments of the Adhesive Material
In an embodiment, the adhesive layer 114 comprises an adhesive material that can bond to both the material of the pad body 112 and to the inner surface 104 of the ring. It is preferable that the adhesive material is non-corrosive and otherwise non-reactive beyond setting 102 or curing 100 to form an adhesive bond, so as to alleviate the risks of damaging a ring 100 to which the pad 110 is applied.
As the skilled person will appreciate, there are three primary means through which an adhesive bond between an object and a surface may fail. The bond may fail between the object, e.g. the pad body 112, and the adhesive layer 114 (‘Object-adhesive failure’); the surface, e.g. the inner surface 104 of the ring, and the adhesive layer 114 (‘Surface-adhesive failure’); or the adhesive layer 114 may fracture, improperly or inadequately cure or otherwise fail (‘internal failure’).
Polysiloxane-Based Adhesive Material
In one preferred embodiment of the present invention, the adhesive material is at least partially a polysiloxane or polysiloxane-based adhesive. In at least the present embodiment, the polysiloxane adhesive is a liquid, gel or putty, and is configured to set or cure into a solid polysiloxane. When used as an adhesive and the pad 110 is applied to an inner surface 104 of the ring 100, the liquid, gel or putty polysiloxane sets or cures into a solid polysiloxane layer between the pad body 112 and the inner surface 104 of the ring 100, bonding to both the pad body 112 and the inner surface 104 of the ring 100 and thus adhering 100 one to the other.
The embodiment wherein the adhesive material is at least partially polysiloxane is considered to be advantageous in that the resulting adhesion is flexible and long-lasting. Polysiloxane compounds are also highly regarded for their resilience against thermal and/or chemical damage. Therefore, in an embodiment wherein the adhesive material is at least partially polysiloxane, the present invention may provide for a semi-permanent means of applying a pad 110 to an inner surface 104 of a finger-ring 100 and improving its ability to be retained upon a finger. It is theorised that using a polysiloxane adhesive may allow for at least one embodiment of the present invention to inhibit, reduce or at least ameliorate the rate of ‘internal failure’ of the adhesive bond, due to the improved flexibility of the polysiloxane adhesive and its resistance to breakdown through thermal and/or chemical damage.
In an embodiment wherein the pad body 112 is at least partially comprised of polysiloxanes, it may be particularly advantageous to use a polysiloxane-based adhesive to form the adhesive layer 114. Without limiting the scope of the invention through theory, it is theorized that the strength of the adhesion between pad body 112 and ring 100 may be improved when the adhesive material is chemically similar to that of the pad body 112 (i.e. both adhesive layer 114 and pad body 112 are polysiloxanes), as the adhesive material will more readily bond with the pad body 112. Therefore, in one particular embodiment, both the pad body 112 and adhesive material are at least partially comprised of polysiloxanes. In at least this embodiment, the polysiloxane adhesive may cure to form a high-strength bond with the polysiloxane pad body 112 due to the similarities in chemical properties. It is theorised that this may enable at least one embodiment of the present invention to inhibit, reduce or at least ameliorate the rate of ‘object-adhesive failure’.
In a further embodiment, the pad body 112 and adhesive material are comprised of polysiloxanes having substantially similar chemical formulae and properties. As the skilled person may appreciate, there are a wide variety of polysiloxanes, and the compatibility between any two may vary. In some circumstances it may be necessary to improve the compatibility between adhesive and pad body 112 by using substantially similar polysiloxanes for both, thereby further improving the strength of the bond between adhesive layer 114 and pad body 112 and further inhibiting, reducing or at least ameliorating the rate of ‘object-adhesive failure’.
Surface Treatment of the Ring
In an embodiment, the inner surface 104 of the ring 100 may require treatment in order to facilitate application and curing 100 of an adhesive, so as to address the rate of ‘surface-adhesive failure’. Many rings are manufactured using either precious metals such as gold, silver, platinum and others, or are otherwise formed of materials that are substantially inert with respect to adhesives. These rings will not readily accept an adhesive, and so the adhesive layer 114 is unlikely to cure and form a suitable adhesive bond. In such an embodiment, the present invention may further comprise a primer to be applied to the portion of the inner surface 104 where the pad body 112 is to be attached. The primer may be an etching primer. This may enable an adhesive to properly adhere to the inner surface 104 portion of the ring 100, and thereby may inhibit, reduce or at least ameliorate the rate of ‘surface-adhesive failure’ of the adhesive bond.
In an embodiment wherein the adhesive is polysiloxane or polysiloxane-based, the use of a surface treatment may be advantageous to improve the ability of the polysiloxane to bond with the material of the inner surface 104 of the ring. Without limiting the scope of the invention, it is theorised that treating the ring 100 with a primer such as an etching primer disrupts the otherwise smooth surface of the inner surface 104 of the ring 100. It is further theorised that this may act to enable, encourage or otherwise facilitate chemical bonding between the polysiloxane-based adhesive and the material of the inner surface 104 of the ring 100 that is otherwise substantially inert with respect to polysiloxane-based adhesives.
Adhesives Other than Polysiloxane and a Pad Base
In an alternate embodiment of the present invention, the adhesive material may comprise an adhesive other than a polysiloxane-based adhesive. The adhesive may comprise a polymer-based adhesive, a resin-type adhesive, an epoxy adhesive or any other form of adhesive that will form a semi-permanent bond to a metallic surface.
In an embodiment wherein the pad body 112 is at least partially comprised of polysiloxanes, it may be disadvantageous or otherwise of limited benefit to use a polysiloxane-based adhesive. However, many non-polysiloxane-based adhesives do not readily bond with a polysiloxane object, and so the pad body 112 may not be able to be adhered to the inner surface 104 of the ring. In such an embodiment and with reference to FIG. 2A, the pad 110 of the present invention may further comprise a pad base 116, being an essentially flat segment of plastic or other suitable material having a pad-receiving side and an opposing adhesive-receiving side. In the present embodiment, the polysiloxane-based pad body 112 may fasten onto and engage with the pad-receiving side of the pad base 116, and the adhesive then adheres the pad base 116 to the inner surface 104 of the ring. Therefore, the adhesive is not required to bond with the polysiloxane of the pad body 112.
As has been previously established, polysiloxane-based compounds do not readily bond or adhere to many substances that are not themselves polysiloxane-based. Therefore, in at least one embodiment and with reference to FIGS. 2B & 2C, the pad-receiving side of the pad base 116 may have contusions, protrusions, ridges or other engageable surface features 118 shaped for the polysiloxane pad body 112 to grip onto. Without limiting the scope of the invention through theory, it is theorised that even though the polysiloxane may not directly bond with the material of the pad base 116, the provision of engageable surface features 118 may enable the polysiloxane to set, cure or otherwise transition into a solid form around, through, or otherwise engaged with the engageable surface features 118 of the pad-receiving side of the pad base 116. This may act to non-adhesively engage the pad body 112 with the pad base 116. The pad base 116 may then be adhered to the inner surface 104 of the ring. As the pad base 116 is formed of a material other than polysiloxane, it is theorised that this may enable the present embodiment of the invention to inhibit, reduce or at least ameliorate the rate of ‘object-adhesive failure’.
Turning specifically to the non-limiting embodiment shown in FIG. 2B, the engageable surface feature 118 comprises a stem with a wide cap. Upon the surface features 118 being immersed in liquid polysiloxane which is then solidified through one or more setting processes, the solidified polysiloxane of the pad body 112 may be non-adhesively engaged with the surface feature 118 and thus retained against the pad base 116. As the skilled person will appreciate, the surface feature may be of any suitable shape that enables the pad body 112 to engage with and be retained by the pad base 116 without departing from the scope of the invention.
In a further embodiment, the engageable surface features 118 may be at least partially hollow. This may enable adhesive material that is applied to the adhesive-receiving side of the pad base 116 to at least partially enter ‘inside’ the pad base 116. This may enable improved interaction of the pad base 116 with the adhesive material, and may promote improved adhesion of the pad base 116 to the inner surface 104 of the ring 100.
Applications of Embodiments of the Present Invention
One application of an embodiment of the pad 110 of the present invention is shown in FIG. 1. A ring 100 with a setting 102 is shown, with a single pad 110 of an embodiment of the present invention applied to an inner surface 104 of the ring. Although the ring 100 is shown with only a single pad 110, the skilled person will appreciate that any number of pads 110 may be attached to the inner surface 104 of the ring 100 without departing from the scope of the invention. In addition, although the pad 110 of FIG. 1 has a particular size relative to the ring 100, pads 110 of an embodiment of the present invention may be sized differently, for example to account for the needs of a particular ring 100 wearer, without departing from the scope of the invention. In particular the pads 110 may be laterally or longitudinally resized in order to cover more or less of the inner surface 104 of the ring 100, and may also be thickened to provide additional cushioning, or thinned to reduce the level of cushioning, without departing from the scope of the invention.
A non-exhaustive range of examples of pad sizes, shapes and arrangements may be found in FIGS. 3A-3E. FIGS. 3A & 3B depict two shapes that the pad 110 may be formed in, as well as some examples of differing number and arrangement of pads 110. FIGS. 3C & 3D depict varying numbers of pads 110 with ring lips 120. Ring lips 120, comprising extensions of the pad body 112 that at least partially ‘wrap around’ the shank of the ring 100, may aid in improving retention of the pad 110 upon the inner surface 104 of the ring. This may be through increasing surface area that remains in adhesive engagement with the ring. The ring lips 120 may also further improve the resistance of the pad 110 to being ‘pushed off’ of the inner surface 104 of the ring 100 as a finger is inserted into or removed from the ring. FIG. 3E depicts a ring 100 with a substantially larger pad 110 covering 100 a large proportion of the inner surface 104. This particular embodiment may be of use in fingers that undergo a large change in diameter, or may be of use in providing additional cushioning and comfort for people with frail or delicate fingers.
In use, at least one embodiment of the pad 110 of the present invention may permit for the ring 100 to be worn on a finger that has a proximal phalanx with a diameter substantially less than that of the finger knuckle. This may be seen in FIG. 4, depicting a ring finger 122 with a knuckle 126 that is wider than the proximal phalanx 124. A ring 100 will require an inner diameter greater than the diameter of knuckle 126 in order to fit onto the finger 122. However the diameter of the proximal phalanx 124 will not properly grip onto a ring 100 that does not have attached pads 110, and the ring 100 may be prone to spinning or rotating about the finger (thereby misaligning and/or hiding the setting 102 if the ring 100 possesses one), or otherwise may slip off of the finger. Attachment of the pads 110 (in any particular embodiment) to the inner surface 104 may permit the effective inner diameter of the ring 100 to be flexible and thereby adapt to the changing diameter as the ring 100 traverses the finger 122.
At least one embodiment of the pad 110 of the present invention may also permit for the ring 100 to be worn on a finger that is tapered, as depicted in FIG. 5. A tapered finger 128, wherein the diameter of the finger 128 steadily increases from fingertip to base, suffers difficulties in wearing 100 a ring 100 in that the finger 128 lacks sufficient structure to prevent a ring 100 from slipping off. An embodiment of the present invention may assist in preventing loss of a ring 100 from a tapered finger 128, by providing an urging force between the finger 128 and the inner surface 104 of the ring 100 and increasing friction therebetween.
With reference to FIGS. 6A & 6B, in at least one embodiment, the pad 110 may cover substantially all of the inner surface 104 of the ring. This embodiment may provide protection against ring slippage, and may also assist in retention of the ring 100 upon a finger should the finger shrink due to, for example, a change in temperature. In such an embodiment, the applied pad 110 may form an ‘inner pad ring’ 210. In some embodiments, the inner pad ring 210 may cover the entire width of the inner surface 104 of the ring. In other embodiments, the pad 210 may only cover a portion of the width of the inner surface 104 of the ring. Without limiting the scope of the invention through theory, it is considered that the present embodiment may improve the ability of the ring 100 to be retained upon a finger without sliding off, in particular if the finger is tapered.
In various embodiments of the present invention, the pad 110 may comprise a range of surface structures 130. In one exemplary embodiment, the surface structure 130 may comprise one or more ridges, positioned on a finger-contacting surface of the pad body 112 adapted to improve grip between the pad 110 and the finger. Two exemplary embodiments may be seen in FIGS. 7A & 7B.
The surface structures 130 may be combined with other embodiments of the present invention. For example, although not shown, an embodiment of the present invention comprising an inner pad ring 210 may comprise ridges positioned on a finger-contacting surface.
Method of Forming a Pad Body of the Present Invention
A second aspect of the present invention relates to a method of producing a polysiloxane pad body 112 for attaching to an inner surface 104 of a ring 100, the method comprising the steps of pouring, injecting or otherwise inserting liquid, gel or putty polysiloxane into a mould; enabling the polysiloxane to set such that it forms into a solid polysiloxane pad body 112; and removing the formed pad body 112 from the mould.
In an embodiment, the mould may provide a plurality of pad 110 bodies. The pad 110 bodies may be removed from the mould as a ‘sheet’ of pad 110 bodies, such that individual pad 110 bodies may be removed as needed, without departing from the scope of the present aspect of the invention.
As the skilled person may appreciate, polysiloxanes may be set through a variety of different processes so as to alter the properties of the resulting solid polysiloxane. In one embodiment, the step of enabling the liquid, gel or putty polysiloxane to set may comprise a sub-step of vulcanising the polysiloxane. The vulcanising may be room-temperature vulcanising, sulfur vulcanising, peroxide vulcanising, alkoxy vulcanising, or any other process (or combination thereof) of vulcanising liquid, gel or putty polysiloxane to obtain a solid polysiloxane.
In an embodiment, the step of enabling the liquid, gel or putty polysiloxane to set may comprise a sub-step of catalysing the setting 102 process through providing a catalytic agent. In at least one embodiment, the catalytic agent may be a platinum-based catalyst. In an embodiment wherein the step of enabling the polysiloxane to set comprises a sub-step of vulcanising the polysiloxane, the catalytic agent may comprise an organotitanate catalyst, tin-based catalyst or other catalytic agent considered to be compatible with the particular vulcanising process being employed.
In an embodiment, the method of producing a polysiloxane pad body 112 may further comprise the step, following removal of the formed pad body 112 from the mould, of applying a surface treatment process. The step of applying a surface treatment process may comprise the application of post-cure treatment to remove at least a portion of polysiloxane curing 100 by-products. The post-cure treatment may comprise the step of applying heat to the formed pad body 112.
In an embodiment, the method of producing the polysiloxane pad body 112 may, following the step of pouring 100, injecting or otherwise inserting liquid, gel or putty polysiloxane into the mould, further comprise the additional step of providing a pad base 116 having an adhesive-receiving side and a pad-receiving side with one or more engaging surface features 118 for the polysiloxane to set, cure or otherwise harden in engagement with. The pad base 116 is inserted into, place on or otherwise introduced to the unset polysiloxane such that the one or more engaging surface features 118 are at least partially submerged within the unset polysiloxane. Upon the polysiloxane setting, curing or otherwise hardening into a solid pad body 112, the polysiloxane may remain in engagement with the engaging surface features 118 and so be retained by the pad base 116.
Method of Using a Pad of the Present Invention
A third aspect of the present invention provides a method of using a pad 110 to prevent a finger-ring 100 from rotating about or slipping off a finger on which the finger ring 100 is worn, comprising the steps of: applying at least one pad 110 comprising an elastically compressible pad body 112 and an adhesive layer 114 to a portion of an inner surface 104 of the finger-ring 100, whereby the adhesive layer 114 adheres to the inner surface 104 portion; allowing the adhesive layer 114 to set; and wearing the ring 100 upon the finger such that the pad body 112 compresses. In use, the compressed pad body 112 urges against the finger, thereby preventing, inhibiting or at least ameliorating rotation or movement of the finger-ring 100 about the finger. In at least one embodiment, the method may further comprise the step of applying an adhesive material to form the adhesive layer 114 prior to applying the pad 110 to the inner surface 104 of the ring.
In at least one embodiment of the third aspect of the invention, the pad body 112 is comprised of polysiloxane. In at least one embodiment of the invention, the adhesive comprises a liquid, gel or putty polysiloxane adhesive. In a further embodiment of the invention, both the pad body 112 and the adhesive are comprised of polysiloxane.
In an embodiment of the invention wherein at least the adhesive is comprised of polysiloxanes, the inner surface 104 may comprise a precious metal or other material that polysiloxane adhesive does not adhere to. In such a circumstance, the method of applying the invention may further comprise the step of, prior to the step of applying the pad body 112 to the inner surface 104 portion of the ring 100, applying an etching primer to a portion of the inner surface 104 of the finger ring 100 so as to prime the inner surface 104 portion. This may enable a polysiloxane adhesive to adhere to the material of the inner surface 104 of the ring.
In an embodiment of the invention wherein the pad body 112 is comprised of one or more polysiloxanes but the adhesive is not, the pad 110 may further comprise a pad base 116 having an adhesive-receiving side and a pad-receiving side engaged with and retaining the pad body 112. In such an embodiment, the method may comprise the step of applying the adhesive to the adhesive-receiving side of the pad base 116 instead of the step of applying the adhesive directly to the pad body 112. The pad base 116 may comprise one or more engaging surface features 118 configured to engage with and retain the pad body 112.
In an embodiment where both the pad body 112 and adhesive are polysiloxane-based, the present invention may provide a method of attaching a polysiloxane pad 110 to an inner surface 104 portion of a finger-ring 100 comprising the steps of: applying a liquid, gel or putty polysiloxane adhesive to a surface of an elastically compressible pad body 112 comprised of polysiloxane so as to form an adhesive layer 114 on the pad 110 surface; applying the pad body 112 to the inner surface 104 portion such that the adhesive layer 114 contacts the inner surface 104 portion; allowing the liquid, gel or putty polysiloxane of the adhesive layer 114 to set and form a solid polysiloxane; and wearing 100 the ring 100 upon the finger such that the pad body 112 compresses.
A Kit Comprising a Pad of the Present Invention
A fourth aspect of the present invention may comprise a kit for a user to attach a pad 110 to a finger-ring 100. In at least one embodiment, the kit may comprise a pad 110 having a pad body 112 and an adhesive layer 114, with an adhesive-preserving seal covering the adhesive layer 114. In an alternate embodiment, the kit may comprise a pad body 112 and a separate portion of adhesive material to be applied by the user to form an adhesive layer 104.
In one embodiment, the pad body 112 is comprised of polysiloxane or a polysiloxane-based material.
