DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(23) FIG. 1 illustrates an example embodiment of a fastener assembly 10 for selectively attaching an ornament to a leather good. In FIG. 1, three components of the fastener assembly are shown without the ornament or leather good. The fastener assembly in its simplest embodiment comprises a base 20, an anchor 40 and a grommet 12 that attaches the base to the leather good.

(24) Shown in FIGS. 2A and 2B, in a further preferred example embodiment of the fastener assembly is a further component of the fastener assembly 10, a disk magnet 50. While the fastener assembly without the magnet is functional, the fastener assembly 10 with the disk magnet 50 is the preferred configuration. FIGS. 2A and 2B are exploded perspective views and FIG. 2B is shown in a perspective inverted from FIG. 2A.

(25) The base 20 has a core 24 having a flat ovoid horizontal cross-section with a top 34, a bottom 30, a pair of flat sides 26 opposite each other and a pair of arcuate sides 28 connecting the flat sides 26 to form the core 24. The arcuate sides 28 have a lip 22 at the top of the core 24, but the flat sides 26 lack the lip and are flat from the top 34 of the core 24 to the bottom 30. The lip 22 itself is flat on the side adjacent to the flat sides 26 of the core 24.

(26) The anchor 40 is an open collar defining a cavity 48 therein, the cavity 48 having an entry 46 and an exit 54. The anchor 40 has a first pair of opposing flanges 42 inside the anchor near the entry 46 to the cavity 48 configured for guiding the base 20 into the cavity 48 of the anchor 40 when coupling the base 20 to the anchor 40.

(27) The anchor 40 has a second pair of opposing flanges 44 near the cavity exit 54, orthogonal to the first pair of flanges 42, the first set of flanges 44 one-half turn from the second set of flanges 44.

(28) The base 20 has a bottom 30 with at least one rivet 32, the at least one rivet, preferably two, inserting into the leather good and fastening on a reverse side of the leather good by the grommet 12 having at least one opening 14, preferably two.

(29) FIG. 3 shows the fastener assembly 10 attaching to a leather lapel 60W. The disk magnet is not shown, nor is the ornament for the sake of clarity. The base 20 permanently attaching to the leather lapel 60W. The anchor 40 surrounds the base 20, the second pair of flanges 44 snug against the flat sides 26 of the base core 24. The second pair of flanges 44 prevent further rotation of the base 20 inside the anchor 40.

(30) The term leather in the present application refers not just to natural leather, but encompasses leather-like material, both natural and synthetic as well as fabric and materials having sufficient structure and bulk to support the fastener assembly. The term leather can mean for example, but not limited to, the treated skins and hides of animals, including mammals, birds and fish as well as to synthetic durable and flexible material with the properties of natural leathers, such as kirza, bicast leather, vegan leather, poromeric imitation leather, and Naugahyde. (Naugahyde is the registered trademark of Uniroyal Engineered Products, Sarasota, Fla. 34236.) The term also can include fabric, materials and cloth such as linen, canvas and duckcloth, providing the structure and bulk is sufficient to support the fastener assembly.

(31) The term good in the present application refers to clothing and accessories. When combined with the term leather as defined hereinabove, as in leather good, it includes, for example, but not limited to, clothing articles such as shirts, sweaters, sweatshirts, jackets and coats, as well as leather trim on the clothing articles listed hereinabove; headwear such as caps, visors, headbands; footwear such as boots, shoes, pumps, sandals and slippers. It includes, but not limited to, accessories such as belts, jewelry made from leather or having leather trim, such as charms, necklaces, earrings, rings, arm cuffs, bracelets, watches, watch straps, tie pins and cuff links, as well as accessories such as clutch bags, clutch purses, handbags, purses, wallets and tote bags and even extends to accessories for a pet such as dog leashes, dog collars and leads.

(32) FIGS. 10, 10, 11 and 11 show the internal structure of the anchor 40. The first pair of opposing flanges 42 are near or substantially adjacent to the entry 46 to the cavity 48. The second pair of opposing flanges 44 are towards the exit 54 of the cavity 48, allowing room for the disk magnet 50 to be placed in the exit 54 in a further example embodiment. The two pairs of flanges 42, 44 are orthogonal to each other, being one-half turn rotation apart.

(33) FIGS. 12A, 12A,12B, 12B, 12C and 12C show the process of the base 20 engaging the flanges 42, 44 when the anchor 40 is disposed on the base. In FIGS. 12A and 12A, the anchor 40 is place over the base so the flat sides 26 of the base are aligned with the first pair of flanges 42. The second pair of flanges 44 prevent the base 20 from further entry into the anchor 40.

(34) FIGS. 12B and 12B show a one-quarter turn rotation of the anchor 40 around the base 20. The base 20 cannot move further into the anchor 40, still blocked by the second set of flanges 44. The first set of flanges 42 prevent the removal of the anchor 40 from the base 20.

(35) FIGS. 12C and 12C show the anchor and base after a full half-turn rotation. The base 20 is fulling disposed within the anchor 40, the lip 22 of the base 20 engaged with the first pair of flanges 42, preventing the removal of the anchor 40 from the base. The flat sides of the base 20 are snug against the second pair of flanges 44, preventing further rotation of the anchor 40, locking the anchor and any attached ornament in place.

(36) FIGS. 4-9 demonstrate a method of selectively attaching an ornament to a piece of leather used as a complete article of clothing or accessory or as a trim. The type of clothing or accessory is not a limitation nor is the type of leather or leather-like material as explained hereinabove.

(37) As shown in FIG. 4, at least one hole 62, preferably two, is punched by hammer 66 and awl 64 into a piece of leather 60. FIG. 5 shows the at least one rivet 32 of base 20 inserting into the at least on hole 62, the rivets protruding into the reverse side of the leather 60R. FIG. 6 shows the grommet 12 with the at least one opening 14 placed over the rivets 32 on the reverse side of the leather 60R and a peening tool 68 being struck by the hammer 66, peening the at least one rivet 32.

(38) As shown in FIG. 7, the base 20 permanently attaches to the leather good 60, held in place by the grommet 12 on the reverse side.

(39) FIG. 8 shows an ornament 70 with the anchor 40 in place. The ornament 70, for the sake of simplicity, is without any features in the drawing, to emphasize that the appearance of the ornament is not a limitation and the style, color, composition of materials, etc. of the ornament is not a limitation. Further, a first ornament 70 is interchangeable with a second ornament and the number of ornaments interchangeable with any one base is limitless. In one example embodiment, the anchor 40 is selectively attached to the ornament 70, rather than permanently attached.

(40) Returning to FIGS. 12A, 12A,12B, 12B, 12C and 12C to demonstrate the method of selectively fastening an ornament to the leather good once the base 20 is attached to the leather good.

(41) A user aligns the first pair of flanges 42 on the anchor 40 attached to the ornament 70, shown in other drawings, with the flat sides 26 of the base 20 as the anchor 40 is placed over the base 20.

(42) The user inserts the base 20 thus aligned into the cavity 48 of the anchor 40 and twists the anchor 40 one-half turn until the lip 22 of the base 20 engages the first pair of flanges 42, the second set of flanges 44 orthogonal to the first set of flanges 42, engaging the flat sides 26 of the base 20, preventing the base from further rotating.

(43) The user pushes the base 20 deep into the cavity 48 of the anchor 40 until it clicks, the base 20 moving past the second set of flanges 44. The disk magnet 50 at an exit 54 of the cavity 48, discussed previously with regard to FIGS. 2A and 2 B, pulls the base 20 deeper into the anchor 40, the flat sides 26 of the base 20 flush against the second pair of flanges 44, further preventing the base 20 rotating within the cavity 48, locking the anchor 40 and base 20 together.

(44) As shown in FIGS. 8 and 9, the disk magnet 50 is between the second pair of flanges 44 and the ornament 70, adjacent to the ornament inside the anchor cavity 48. The first pair of flanges 42 and the second pair of flanges 44 are in the cavity in the position described hereinabove.

(45) The user removes the ornament 70 from the leather 60, by removing the anchor 40 from the base 20, thus removing the ornament 70 from the leather 60, by pulling the anchor 40 away from the base 20 until the second set of flanges 44 no longer engages the flat sides 26 of the base 20, rotating the anchor 40 one half-turn until the first set of flanges 42 no longer engages the lip 22 of the base 22, and lifting the anchor 40 off the base 20.

(46) In one example embodiment, the step of removing the anchor 40 from the base 20 further comprises breaking the magnetic attraction between the disk magnet 50 and the base 20 when pulling the anchor 40 away from the base.

(47) FIG. 9 shows the ornament 70 selectively attaching to the leather front 60F, held in place by the fastener assembly 10. A plurality of anchors 40, each with one ornament 70 attached interchangeably couple with the base.
