DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(8) Exemplary embodiments of the invention will be described below.

(9) FIGS. 2-4 illustrate a first exemplary embodiment of present invention directed to a stud type earring 20. As shown, earring 20 generally includes a back 21, a base plate 23, a plurality of prongs 22 that are spaced from each other and project from one face of the base plate and are used to secure a decorative item 25, such as a gemstone, a circular member 27 which connects intermediate portions of the prongs 22 and which also helps to secure the decorative item 25, and an elongate post 24 which projects from an opposite face of the base plate at a central portion thereof, and which is configured to be securely received in openings 46, 56 defined in the back 21. The prongs 22 and the circular member 27 may be dimensioned and shaped so as to grip decorative item 25 and secure the decorative item 25 to the base plate 23. The particular structure of the earring 20 apart from the back 21 and that the earring includes the post 24 for being secured to the back is not important to the present invention. Hence, other portions of the earring may have essentially any desired structure and appearance, e.g., the decorative item 25 may be other than a gemstone and may be integrally formed with prongs 22, etc. As depicted, the post 24 has a distal end 30 which extends furthest away from the base plate 23 and which will extend through the openings 46, 56 in the back, while some portion of the post 24, including the distal end 30, may have grooves defined in an outer surface thereof which help maintain the back secured to the post.

(10) The back 21 may include a first larger receiver 43 and a second smaller receiver 52 each of which are concave or conical in shape and which respectively include the central openings 46, 56 defined therein. The first and second receivers 43, 52 may be fixed in together in any appropriate manner such that the first and second openings 46, 56 are coaxially aligned with a space therebetween and such that the second receiver 52 is disposed farther away from the user's ear lobe than the is the first receiver 43 when the back 21 is engaged against the user's ear lobe.

(11) As depicted, the first receiver 43 may have a smooth concave or substantially conical surface 44 on one side thereof and a convex or substantially convex surface 48 on an opposite side thereof which extends toward the second receiver 52. The opening 46 is defined through a center of the first receiver 43 and the opening 56 is defined through a center of the second receiver 52, while both holes have the same diameter which is appropriate to securely receive a post of a standard earring therein such as the post 24. For example, the openings 46, 56 may have a diameter which is slightly larger than the outer diameter of the post 24, while the surfaces defining the openings may be smooth or threaded, e.g., a threaded opening may include threads configured to securely receive the threads provided on the outer surface of the post 24. The first opening 46 may be positioned at a most recessed position of the first recessed, substantially conical surface 44, and the first recessed, substantially conical surface 44 may have a circular circumference. These features are particularly useful for easily guiding the end 30 of the post 24 into the first opening 46. The shape of the opposite side surface 48 is not especially important and may be other than convex.

(12) As shown, the first receiver 43 may be substantially conical in shape, with a substantial “V” shape or a funnel shape appearance in side view, a rounded or curved lip 49 which will engage against the user's ear lobe, and a short tubular extension 50 which axially extends from the surface 48 and has a portion of the central opening 56 defined therethrough. Again, an inside surface the portion of the opening 46 in tubular extension 50 may be smooth or threaded.

(13) The second receiver 52 may have a second recessed, substantially conical surface 54 having a second opening 56 defined through a center thereof which is also configured to securely receive any standard earring post such as the post 24 of the stud earring 20 therein similar to the first opening 46. The second receiver 52 may be fixed to the first receiver 43 in any appropriate manner such that the first and second openings 46, 56 are coaxially aligned in spaced relation and such that the second receiver 52 is disposed farther away from the user's ear lobe than is the first receiver 43 when the back 21 is secured to a earring post and engaged against the user's ear lobe. The second receiver may have a size which is different from the size of the first receiver, but could be the same size. In the depicted embodiment the second receiver 52 is smaller than the first receiver 43, and a pair of opposed connecting walls or shanks 58 are provided to connect the first and second receivers together in a fixed relationship.

(14) When the wearer desires to attach the back 21 to the earring post 24, e.g., when the user is attaching an earring to the user's ear, the earring back is moved toward the distal end 30 of the post 24 so that the distal end 30 engages the first recessed, substantially conical surface 44 of the first receiver 43 and is conveniently guided towards and into the first opening 46 at the most recessed part of the first receiver 43 based on the smooth, concave, substantially conical shape of the surface 44 and the position of the first opening 46 at the central, most recessed part of the surface 44. After the distal end 30 passes through the first opening 46 and moves towards the second receiver 52, the second recessed, substantially conical surface 54 of second receiver similarly guides the distal end 30 towards and into the second opening 56 of the second receiver 52 based on the smooth, concave, substantially conical shape of the surface 54 and the position of the second opening 56 at the central, most recessed part of the surface 54. Of course, once the distal end 30 of the post has been extended through the first opening 46 it's movements will be restricted to some extent by the engagement between the first opening 46 and the post, but the concave shape of the second receiver 52 will still help to guide the distal end 30 of the post into the opening 56. Thus, the user may easily slide the distal end 30 of the post sequentially into the openings 46, 56 of the back 21. In this way, the back 21 securely engages the post 24 to hold the earring 20 in the user's ear lobe.

(15) Again, some portion of the post 24, such as the distal end 30, may have grooves formed in the outer surface thereof as depicted which may be screwed or pushed into mating threads formed in surfaces of the first and/or second openings 46, 56 to better secure the post and the back together if so desired. Also, the curved lip 49 of the first receiver 43 may have ridges formed on the outer surface thereof which may help a user to better grip and manipulate the earring back 21.

(16) FIGS. 5-6 show a stud type earring 90 including a post 92 and a second exemplary embodiment of an earring back 91 according to the present invention. Besides the earring back 91, the remainder of the earring 90 is essentially the same as the earring 20 of the first embodiment and is not discussed here. The back 91 generally includes a first receiver 93 which is similar to the first receiver 43 in the first embodiment, together with a second receiver which includes an opposing pair of flexible projections 97, 98 extending away from a side of the first receiver 93 and having rounded end portions which are spaced from the receiver 93 and define a gap 95 therebetween.

(17) The first receiver 93 may have a smooth, recessed or concave, substantially conical surface 94 on one side thereof, a convex, substantially conical surface on an opposite side thereof and an opening 96 defined through a center thereof which is configured to securely receive the post 92 of the stud earring therein. For example, the opening 96 may have a diameter which is just slightly smaller than the outer diameter of the post 94, the surface defining the opening 96 may be threaded to better receive the threads formed on the outer surface of the post 92, etc. As shown, the opening 96 may be positioned at a most recessed position of the recessed, substantially conical surface 94, and the recessed, substantially conical surface 94 may have a circular circumference. These features are particularly useful for easily guiding the end 30 of the post 24 into the opening 96. The shape of the opposite side surface of the receiver 93 is not especially important but should not interfere with the flexible projections 97, 98. The first receiver 93 may also include a tubular extension which projects from the opposite side surface thereof similar to the extension 50 in the first exemplary embodiment, although no such extension is depicted in FIGS. 5-6.

(18) The flexible projections 97, 98 of the second receiver may project away from a side of the first receiver 93 opposite to the concave, substantially conical surface 94 and the end portions of the flexible projections 97, 98 may curve inwardly towards each other to define the gap 95 therebetween, which is spaced from and aligned with the opening 96 of the first receiver. Use of such stud-gripping projections in earring backs is commonly referred to as a “butterfly” arrangement. A width of the gap 95 is substantially the same as a diameter of the post 92 so that when the post is inserted through the gap opposing surfaces of the end portions of the flexible projections will securely grip the post. The width of the gap 95 may be slightly smaller than the diameter of the post 94 such that when the post is inserted into the gap the end portion of the projections 97, 98 elastically flex away from each other to better grip the post with a small spring force. While two projections 97, 98 are used in this embodiment, the second receiver may include a different number of projections such as three or four.

(19) When the wearer desires to attach the earring back 91 to the post 92, the earring back is moved toward the distal end 30 of the post 92 so that the distal end of the post engages the first recessed, substantially conical surface 94 of the first receiver 91 and is conveniently guided towards and into the opening 96 at the most recessed part of the first receiver 43 based on the smooth, concave, substantially conical shape of the surface 94 and the position of the opening 96 at the central, most recessed part of the surface 94. After the distal end of the post passes through the opening 96 and moves towards the gap 95 of the second receiver, the rounded end portions of the projections 97, 98 guide the distal end 30 toward and into the gap 95 based on the smooth, rounded shape of the end portions and the aligned position of the gap relative to the opening 96. Thus, the user may easily slide the distal end of the post 92 sequentially into the opening 96 and the gap 95 of the earring back 91. In this way, the back 91 securely engages the post 92 to hold the earring 20 in the user's ear lobe. Again, some portion of the post 92, such as the distal end, may have grooves formed in the outer surface thereof which my be screwed or pushed into mating threads formed in a surface of the opening 96 and/or into the gap 95 to better secure the post and the back together, if so desired.
