BACKING FOR AN EARRING, AND EARRING WITH A BACKING

Abstract

The invention relates to a backing for an earring, and to an earring with a backing. The backing is particularly suitable for a stud earring but is not limited to those applications and can also be used for a drop earring or hook earring if desired. The backing has a hole which is sized to accommodate a post of the earring and to be a frictional fit upon the post, the backing having a substantially planar surface which lies against the user's ear lobe in use, the hole extending in a direction which is substantially aligned with the substantially planar surface. The earring has a post with a first portion, a second portion and a bend between the first portion and the second portion. The backing is designed to fit to the second portion.

DETAILED DESCRIPTION

[0059] The same numerals will be used for similar parts in the prior art arrangement of FIG. 1 and the present invention of FIGS. 2-8, for ease of understanding.

[0060] In common with GB 2 572 067, the stud earring 10 comprises a stud 12 mounted to a post 14. In common with traditional stud earrings, the post 14 is preferably of circular cross-section throughout its length. The stud 12 in these examples is represented as a substantially spherical component mounted directly to the post 14, but can be any suitable form, for example a rigidly mounted jewel. In an alternative embodiment the earring can be a “hook earring” (in which case the post is extended downwardly to the left-hand and right-hand sides of the ear lobe 20 as viewed), or a “drop earring” (in which case a dropper is suspended directly or by way of a chain to the left-hand end of the post 14) as desired.

[0061] The post 14 has a linear first portion 16 which passes through a piercing 18 in a user's ear lobe 20. Whilst the drawings show the piercing 18 as a relatively tight fit around the post 14 that is not always the case and the wearing of heavy earrings in particular can over time stretch the piercing, increasing the requirement for a secure backing.

[0062] A backing 22 is fitted to the post 14 and secures the post in position relative to the ear lobe 20. Thus, whilst a gap is shown between the stud 12 and the ear lobe 20, and another gap is shown between the backing 22 and the ear lobe 20, that is solely for the purpose of clarity and in practice in the prior art and in the present invention the ear lobe 20 will preferably be clamped between the stud 12 and backing 22.

[0063] In a conventional stud earring with a linear post the requirement for an effective frictional grip of the backing 22 upon the post increases as the weight and size of the stud 12 increases. Larger and heavier studs will tend to cause the ear lobe to distort so that the first portion 16 of the post 14 is no longer horizontal as drawn, and instead is angled downwardly. Larger and heavier studs furthermore increase the tendency of the post to slide through the backing and piercing and to fall from the ear lobe (or alternatively stated increase the tendency of the backing inadvertently to migrate along and off the post).

[0064] In common with GB 2 572 067 the post 14 has a bend 24 between the first portion 16 and a second portion 26. In this embodiment the bend 24 is a 90° bend but it will be understood that a bend of precisely 90° is not required and angles several degrees more or less than 90° are within the scope of the present invention. The backing 22 has a substantially planar (front) surface 30 which in use lies against the user's ear lobe 20. The backing 22 has a hole 32 therethrough which can accommodate the post 14. In known fashion the backing 22 is made from a flexible and resilient material (in this embodiment silicone) and forms a friction grip upon the post 14.

[0065] As is clear from FIG. 2, in the present invention the longitudinal axis A-A of the hole is parallel with the plane of the surface 30. This contrasts with the prior art arrangement of FIG. 1 (and with traditional backings for stud earrings) in which the hole in the backing is perpendicular to the surface of the backing which lies against the ear lobe.

[0066] Accordingly, whereas the backing of GB 2 572 067 in use is located upon and secured to the first portion 16, with the present invention the backing 22 in use is located upon and secured to the second portion 26. This has several advantages in practice.

[0067] Firstly, during fitment of the backing 22 the user moves the backing relative to the post 14 in the direction of the arrow F of FIG. 2 (and conversely during removal the backing is moved in the direction −F). It will be understood that in use the weight of the stud 12 can distort the ear lobe 20 so that the earlobe moves in the anti-clockwise direction from the orientation shown in FIG. 2 and a component of the weight of the stud 12 acts to pull the earring 10 through the piercing 18 in the relative direction W, and consequently acts to pull the backing 22 in that relative direction also. Since the backing 22 cannot pass the ear lobe 20 the weight of the stud effectively acts to move the backing 22 relative to the post 14 in the direction −W. Because the relative direction −W is perpendicular to the direction −F the weight of the stud 12 does not act directly to remove the backing 22 from the post 14 and consequently the frictional grip of the backing upon the post is not required to directly oppose the weight of the stud.

[0068] Secondly, according to engineering principles the frictional resistance to forced (or inadvertent) movement of the backing 22 along the post 14 is not dependent upon the contact area between the backing and the post. Nevertheless, experience suggests that increasing the length of the hole increases the resistance to unwanted movement of the backing and makes the earring more secure. The length of the hole 32 is dependent upon the cross-sectional area (in this embodiment the approximate radius) of the backing 22 rather than the thickness of the backing and in practice the length of the hole 32 (and therefore the contact area between the backing and the post) can be significantly greater than for a prior art plastic backing.

[0069] Thirdly, the backing 22 is not required to pass around the bend 14 during fitment and removal. The dimensions of the hole 32, and the flexibility of the material from which the backing 22 is made, can therefore be determined by the required friction grip upon the post without the potential compromise of the backing having to pass around the bend. As above stated, because the backing 22 according to the present invention is not stretched repeatedly as it passes around the bend during fitment and removal it suffers significantly less strain and is thereby likely to remain usable for a much greater period of time.

[0070] As above explained, it will be appreciated that none of these advantages rely upon a right-angled bend in the post 14, and bends other than 90° are within the scope of the present invention. A post with an angle between the first portion and the second portion which is as small as 60° might be acceptable for some stud earrings (with the hole in the backing oriented at a corresponding angle (30° in this example) relative to the surface 30). Clearly, the smaller the angle through which the post is bent the less secure the backing will be. Bend angles significantly greater than 90° can also be provided, again with the hole in the backing oriented at a corresponding angle relative to the surface 30. Larger bend angles will increase the security provided by the backing but will increase the difficulty of fitting the backing to the post.

[0071] It will be seen from a comparison of FIGS. 1 and 2 that the length of the free end of the post 14 which projects beyond the backing 22 (and which part which might be pressed against the user's neck) is significantly reduced as compared to the prior art arrangement (and is similarly significantly reduced as compared to a traditional stud earring). In practice with a backing of the present invention the projecting part might be only around 1 mm or so in length and such a small projection would be expected to cause little or no discomfort to the user. During removal of the backing, however, the user can readily locate the projecting part by touch alone and can therefore properly direct the force to remove the backing 22, even though the backing will usually not be visible.

[0072] It will be understood that in an alternative (but less preferred) arrangement the length of the hole in the backing exceeds the length of the second portion 26 so that the free end of the post lies within the body of the backing 22. In such an arrangement the hole 32 does not need to extend to the peripheral edge of the backing. It will also be possible for the user of a backing 22 to push the backing only part-way along the portion 26 of the post so that the free end of the post remains within the body of the backing 22 if that is desired.

[0073] FIGS. 3-5 show views of an alternative backing 122 according to the present invention. It will be seen that the surface 130 is substantially planar except for a trough 40 formed in the backing 122. The trough 40 extends from a peripheral edge of the backing to a wall 42 which lies at the approximate centre of the backing 122. The hole 132 extends from the wall 42 to the peripheral edge of the backing 122. The hole 132 has a longitudinal axis A-A and in this embodiment the trough 40 shares the same longitudinal axis.

[0074] As most clearly seen in FIGS. 4 and 5, the wall 42 surrounding the end of the hole 132 slopes towards the hole so as to provide a guide or lead-in for the free end of the post 14 during fitment.

[0075] As seen in particular in FIG. 5, the side walls of the trough are angled relative to each other and taper towards the hole 132. Also, as seen in FIG. 3, the bottom of the trough 40 is aligned with the (bottom) edge of the hole 132. The tapering side walls and the bottom wall of the trough can thereby also act to guide the free end of the post 14 towards the hole during fitment. These features can be particularly beneficial in practice as the user will typically be unsighted as the backing is fitted to the post.

[0076] The backing 122 is a substantially circular disc. The periphery of the disc has two parallel flats 44, the flats 44 being aligned with the longitudinal axis A-A. The purpose of the flats 44 is to assist the user in aligning the trough 40 and hole 132 with the second portion 26 of the post during fitment. An alternative embodiment does not include flats and the backing is a circular disc.

[0077] FIG. 3 shows that the backing 122 has a domed (back) surface 46 opposing the planar (front) surface 130. The domed surface 46 helps to minimise localised regions of high pressure which might otherwise occur at the periphery of the back surface in the event that the backing is pressed against the user's neck, and which regions might cause discomfort over time (for example during sleeping).

[0078] The domed surface 46 also helps the user to distinguish between the surfaces 130 and 46 by feel alone, and thereby to properly orient the backing 122 during fitment even if it is not visible.

[0079] It will be seen that the depth of the trough 40 is less than the thickness of the backing 122, so that the trough does not extend all the way to the domed surface 46. The domed surface 46 is therefore continuous and aesthetically pleasing. The backing can if desired be made flesh coloured so as to be unobtrusive, being provided in a number of colours to suit different skin colours if desired.

[0080] In the alternative embodiment of FIG. 2 the trough is extended all the way through the backing 22 so that the surface 50 (which opposes the surface 30) is similarly discontinuous. Also in the alternative embodiment of FIG. 2 the surface 50 is substantially planar. These features allow the backing 22 to be reversible in that it can be fitted to the post 14 in two different orientations, i.e. with the substantially planar surface 30 being the front surface which lies against the ear lobe 20 or the substantially planar surface 50 being the front surface which lies against the ear lobe 20. As seen in FIG. 2 the backing 22 is not symmetrical and the longitudinal axis A-A of the hole 32 is offset from the central plane C-C of the backing 22. Fitting the backing 22 in its alternative orientation therefore varies the spacing between the portion 26 of the post 14 and the user's ear lobe 20. Accordingly, the backing 22 can be worn by users having different-thickness ear lobes, and/or can be used with earrings 10 having a different spacing between the stud 12 and the bend 24.

[0081] The backing 122 of FIGS. 3-5 cannot be reoriented. A range of backings with different thicknesses suited to different users and/or earrings can nevertheless be provided. Alternatively, washers or spacers (not shown) can be used as required with different thickness ear lobes and/or different earrings.

[0082] It is envisaged that two (or perhaps more) pairs of backings 122 could be provided with each pair of stud earrings, the pairs of backings having different thicknesses suited to users with different thickness ear lobes. The significant cost benefit over a traditional butterfly clasp for example is expected to make it cost-effective to provide multiple backings with a set of earrings.

[0083] It is another benefit of the backing 122 that the trough 40 can readily be located and positioned by touch alone; tests have demonstrated that some users find it easier to fit a backing 122 (with a trough which is open at the front surface of the backing only) than a backing 22 (with a trough which is open at the front and back surfaces of the backing). One reason for this is believed to be that the bottom of the trough is used to guide the free end of the post towards the hole as the backing is fitted to the post.

[0084] FIG. 6 shows a backing 222 which is similar to the backing 122 of FIGS. 3-5 except that it does not have the flats 44 and instead is a disc with a circular periphery. In addition, the curvature of the back surface 246 has been extended and terminates adjacent to the hole 232. It will be understood that alternative embodiments could have an oval periphery, or a periphery comprising a number of straight edges (and combinations of these alternative shapes are also possible).

[0085] FIGS. 7 and 8 show another embodiment of backing 322 according to the present invention, which shares the reversible and offset hole features of the embodiment of FIG. 2 and the ease of fitment features of FIGS. 3-5. The backing 322 is a substantially circular disc with a substantially planar first surface 330 and a substantially planar second surface 430. The backing 322 has a first trough 340 and a first hole 332. The first trough 340 is open to the first surface 330 of the backing but is not open to the second surface 430.

[0086] The backing 322 has a second trough 440 and a second hole 432. The second trough 440 is open to the second surface 430 of the backing but in not open to the first surface 330. Because both of the troughs 340, 440 are open to only one of the opposing surfaces the user is better able to position and align the chosen trough and hole with the earring post in use.

[0087] Significantly, the first trough 340 and first hole 332 are oriented at approximately 90° to the second trough 440 and second hole 432. A 90° separation has been found to be ideal for enabling a user to correctly position and align the chosen trough and hole (and for example a 180° separation has been found to cause potential confusion for the user).

[0088] The depth of the first and second troughs differs whereby to provide some adjustment for the user. In particular the first trough 340 has a depth D1 (i.e. from the first surface 330) and the second trough 440 has a depth D2 (i.e. from the second surface 430). The difference between the depths D1 and D2 might be around 1 mm for example, enabling the backing 322 to be used with ear lobe thicknesses differing by around 1 mm.

[0089] The backing 322 can be used with a larger range of ear lobe thicknesses if it is made of a relatively compressible material (such as a soft silicone), and one or both of the depths D1 and D2 could be increased for example. Similarly, the thicknesses of the backings 22, 122 and 222 could be increased when a relatively compressible material is used.

[0090] Whilst FIGS. 7 and 8 show a relatively sharp corner between the first surface 330 and the peripheral edge of the disc, and similarly a relatively sharp corner between the second surface 430 and the peripheral edge of the disc, in practice those corners would be rounded to increase the comfort for the user.

[0091] The holes 32, 132, 232, 332, 432 are slightly smaller than the post 14 in order to provide the desired frictional grip. Practical embodiments of the invention have a backing 22, 122, 222 comprising a substantially circular disc with a diameter of between approx. 5 mm and 10 mm (larger diameter backings being suitable for heavier earrings). The hole 32, 232, 332, 432 may be around 0.5 mm in diameter and between approx. 2 and approx. 5 mm long (although the hole diameter in particular is dependent upon the flexibility and stretchability of the backing material). It is expected that such backings could be used with posts 14 having a diameter of approx. 0.6 mm to approx. 1 mm.

[0092] The hole 32, 132, 232, 332, 432 extends to the approximate centre of the respective backing 22, 122, 222, 322. Accordingly, and as with the prior art arrangement of FIG. 1, the backing substantially surrounds the first portion 16 of the post 14 and consequently substantially surrounds the piercing 18. Such an arrangement is not essential and it would alternatively be possible for the hole to extend from one peripheral edge of the backing to the opposing peripheral edge. It is, however, preferable for the backing to surround the piercing as shown.
