BEST MODE FOR CARRYING OUT THE INVENTION

[0052] The presently preferred best mode for practicing the present invention is illustrated by way of example in FIGS. 1 to 6.

[0053] Referring to FIG. 1, shown is a cured solid polymer clay earring 100, a flat padded earring post 120, consisting of a flat pad 121 attached to an earring post 122 having a pad edge 123 that defines the pad diameter, and a preferred alignment tool 110 having an alignment pocket 111 a horizontal offset distance from the closest portion of a substantially straight alignment fence 112 on a bottom surface, and an alignment point 113 the same horizontal offset distance from the alignment pocket 111 on a top surface. Preferably, the alignment tool is used to offset the flat pad 121 and earring post 122 an appropriate distance away from the edge of the polymer clay earring 100, which edge could be convex or concave, to prevent the dome of uncured solid polymer clay 500 (see below) from extending beyond the earring's edge (although manual positioning could be used instead, if desired). Preferably, the alignment pocket 111 has a pocket diameter approximately equal to the diameter of the flat pad 121, so that the alignment pocket 111 can snugly receive the flat pad 121, and the pad edge abuts against the alignment pocket. For offsetting from a convex edge of the earring by the offset distance, the alignment fence 112 of the alignment tool 110 is placed against the convex edge 101 (as shown in FIG. 1A) of the cured solid polymer clay earring 100, and the pad edge 123 is then placed against the alignment pocket 111. Preferably, the polymer clay earring 100 is cured before embedding the flat padded earring post 120 to avoid distortion during the embedding process. The flat pad 121 may optionally be temporarily attached to the cured solid polymer clay earring 100 by means of a small amount of cyanoacrylate glue or similar (not shown).

[0054] Referring to FIG. 1A, the same configuration of parts is shown from below to make evident the contact between the convex edge 101 of the cured solid polymer clay earring 100 and the alignment fence 112.

[0055] Referring to FIG. 2, shown is a cured solid polymer clay earring 100, a flat padded earring post 120, and the alignment tool 110, which is inverted from the orientation shown in FIG. 1. The alignment point 113 of the alignment tool 110 is placed against a concave edge 102 (as shown in FIG. 2A) of the cured solid polymer clay earring 100. The edge of the flat pad 121 is then placed against the alignment pocket 111.

[0056] Referring to FIG. 2A, the same configuration of parts is shown from below to make evident the contact between the concave edge 102 of the cured solid polymer clay earring 100 and the alignment point 113.

[0057] Referring to FIG. 3, shown is a quantity of uncured solid polymer clay 320, having been rolled to a consistent thickness of the thickness guides 300 using a roller 310, as is familiar to a person of ordinary skill in the art, that is, an artisan. A disk-cutting tool 330 is then pressed firmly into the uncured solid polymer clay 320, by means of the ergonomic grip 331, and then removed. Optionally, the disk-cutting tool 330 could have a non-stick coating, or a release agent such as cornstarch, water or dimethicone (sold under the trademark Armor All) may be used on the disk-cutting tool 330 to prevent the uncured solid polymer clay 320 from sticking to it.

[0058] The disk-cutting tool 330 may include a measuring recess 335, which allows the artisan to determine if the flat pad 121 is of the size for which the embedding tool is designed, as described below. This feature is provided as an optional convenience feature and does not affect the core functionality of the invention. The inclusion of this feature allows artisans to select the correctly sized tools by simply placing the flat pad 121 into the measuring recess 335. This feature is not intended to limit the scope of the invention, and alternative versions may or may not include this optional measuring feature.

[0059] Referring to FIG. 3A, shown is a sectional view of the portion of the disk-cutting tool 330 that acts on the uncured solid polymer clay 320. The cutting edge 332 forms a circular cut that creates a disk of uncured solid polymer clay 340 (see FIG. 3B) and the center-marking point 333 forms a preferred center mark 341 (see FIG. 3B) in the surface of the disk of uncured solid polymer clay 320. The circular cutting edge 332 and the center marking point 333 define a cavity 334. In an alternative embodiment, the preferred center-marking point 333 pierces completely through the disk of uncured polymer clay 320. An ergonomic grip 331 provides a means of pressing the disk-cutting tool 330 into the uncured solid polymer clay 320 with sufficient force to cut out the disk of uncured solid polymer clay 340 as seen in FIG. 3B. The cavity 334 of the disk-cutting tool has a sufficiently greater height than the thickness of the uncured polymer clay 320 to avoid adversely affecting the cutting of the disk of solid polymer clay 340.

[0060] Referring to FIG. 3B, shown is the resulting disk of uncured solid polymer clay 340, including a preferred center mark 341 which was formed by the center marking point 333. Notably, the dimensions of the disk of uncured solid polymer clay 340 are determined only by the height of the thickness guides 300 and the diameter of the cutting edge 332 of the disk-cutting tool 330, therefore the volume of the disk of uncured solid polymer clay 340 is the height of the disk times the area of the circular surface of the disk.

[0061] The volume of the disk of uncured solid polymer clay 340 is preferably a measured amount obtained by selecting a cutting tool having the appropriate diameter of cutting edge 332, based on the diameter of the flat pad 121, to provide a sufficient excess diameter and attachment surface beyond the flat pad 121 after the dome has been formed, as described in more detail below.

[0062] Referring to FIG. 4, shown is the flat pad positioned on the earring 100 and the disk of uncured solid polymer clay 340 ready to be impaled onto the earring post 122, preferably through the center mark 341 (not visible in FIG. 4 because it is on the underside of the disk of uncured solid polymer clay 340). The post hole 403 of the dome-forming tool 400 is then fitted over the earring post 122, and the dome-forming tool 400 is pressed firmly over the disk of uncured solid polymer clay 340, by means of the ergonomic grip 401, and then removed. Preferably, the dome-forming tool 400 is also twisted during pressing, for a smooth dome-shaped appearance. Optionally, the dome-forming tool 400 could have a non-stick coating, or a release agent such as cornstarch, water or dimethicone (sold under the trademark Armor All) may be used on the dome-forming tool 400 to prevent the disk of uncured solid polymer clay 340 from sticking to it.

[0063] Referring to FIG. 4A, shown is a sectional view of the portion of the dome-forming tool 400 that acts on the disk of uncured solid polymer clay 340. The centered post hole 403 receives the earring post 122, and therefore also centers the dome-forming tool 400 on the flat pad 121. The earring post 122 also projects through the post hole 403 allowing the dome forming tool 400 to press the disk of uncured polymer clay 340. The dome-shaped void 402 transforms the disk of uncured solid polymer clay 340 into a seamless dome of uncured solid polymer clay 500. The dome-shaped void 402 exceeds the diameter of the flat pad 121 by an excess diameter. An ergonomic grip 401 provides a means of pressing the dome-forming tool 400 into the disk of uncured solid polymer clay 340 with sufficient force to form the dome of uncured solid polymer clay 500 as seen in FIG. 5.

[0064] Optionally, the dome-shaped void 402 of the dome-forming tool could be formed in the dome-forming tool by using interchangeable inserts to create different dome sizes or shapes for various sizes of flat padded earring posts.

[0065] Referring to FIG. 5, shown is the dome of uncured solid polymer clay 500 which now completely encases the flat pad 121 and extends beyond the flat pad 121 by the excess diameter, forming an annular (ring shaped) embedding zone 510, and the embedding zone directly contacts the clay earring 100, and thereby connects the dome of uncured solid polymer clay 500 (with the flat pad 121 embedded) to the cured solid polymer clay earring 100. When the assembly of the clay earring 100 and the dome of uncured solid polymer clay 500 is subsequently cured, the embedding zone 510 of the dome of uncured solid polymer clay 500 will be effectively fused with the cured solid polymer clay earring 100 into a continuous solid material, which thereby embeds the flat pad 121 into the cured solid polymer clay earring 100.

[0066] Referring to FIG. 5A, shown is a perspective view of the assembly shown in FIG. 5 from below, with a cutout revealing the flat pad 121 embedded inside the dome of uncured solid polymer clay 500, with the embedding zone 510 directly contacting the cured solid polymer clay earring 100.

[0067] Notably, the volume of the dome-shaped void 402 approximately equals the sum of the volume of the disk of uncured solid polymer clay 340 and the volume of the portion of the flat padded earring post 120 that lies within the dome-shaped void 402, such that there is neither too much nor too little material to form the dome of uncured solid polymer clay 500, thus avoiding overflow of excess solid polymer clay, or insufficient uncured solid polymer clay to completely form the dome 500, when the dome-forming tool 400 is pressed on the disk of solid polymer clay 340 to form the dome 500.

[0068] Also, the dome-shaped void 402 must be shaped to provide a sufficiently large excess diameter to provide a sufficiently large embedding zone when the dome of uncured solid polymer clay 500 is formed. The dome-shaped void 402 has a volume equal to the measured volume plus the volume of the portion of the flat padded earring post embedded in the dome of uncured solid polymer clay 500.

[0069] Preferably, the following are preferred for the diameters of round flat pads and corresponding domes, to provide sufficiently large attachment areas:

TABLE-US-00001 Diameter of flat pad Diameter of dome 3 mm 8 mm 4 mm 9 mm 5 mm 10 mm 6 mm 11 mm 8 mm 12 mm

[0070] Of course, different sizes of flat pad 121 require different sizes of disk-cutting tool 300 and dome forming tool 400.

[0071] Referring to FIG. 6, shown is an alternative method of using the present invention. The disk of uncured solid polymer clay 340 is impaled onto the earring post 122, preferably through the center mark 341. The earring post 122 is then inserted into the post hole 403 of the dome-forming tool 400. Finally, the cured solid polymer clay earring 100 is pushed firmly onto this assembly, forming the disk of uncured solid polymer clay 340 into the dome of uncured solid polymer clay 500 as shown in FIG. 5.

[0072] This alternative method can be used in multiple ways, such as the dome-forming tool 400 may sit on a work surface with the dome-shaped void 402 facing up and the cured solid polymer clay earring 100 in the artisan's hand, or with the dome-forming tool 400 in one hand and the cured solid polymer clay earring 100 in the other hand.

[0073] Alternative methods of using the dome-forming tool 400 may be preferred and are appropriate when precise placement of the flat padded earring post 120 is not required. Additionally, uneven details on the front of the cured solid polymer clay earring 100 may prevent it from sitting flat on a work surface as shown in FIG. 4. Therefore, the artisan may prefer to hold both the cured solid polymer clay earring 100 and the dome-forming tool 400 each in one hand.

[0074] After the flat padded earring post 120 has been aligned, and embedded in and attached to the earring 100 by the embedding zone of the uncured solid polymer dome 500, as described above, the uncured solid polymer dome 500 and the polymer clay earring 100 are cured together, to complete the process.

[0075] To summarize, the invention provides embedding tools for attaching flat padded earring posts to cured solid polymer clay earrings and the like, comprising a combination of tools for preparing a measured amount of uncured solid polymer clay (which is equal to the volume as the dome-shaped void 402 in the dome-forming tool 400) into a disk of uncured solid polymer clay or similar shape (although equivalent methods that provide consistent and repeatable volume can also be used). The tools include a dome-forming tool for pressing the disk of uncured solid polymer clay into a dome shape that embeds the flat pad and forms an embedding zone, wherein the dome-forming tool includes variations in geometries and functional configurations to suit different aesthetic needs.

[0076] In more detail, thickness guides, a roller, and a disk-cutting tool are used to form a measured amount of uncured solid polymer clay into a disk shape having a volume of clay sufficient to embed the flat pad in a dome with an excess diameter to form an embedding zone.

[0077] The disk-cutting tool also marks the center of the disk of uncured solid polymer clay for accurate positioning of the flat padded earring post.

[0078] A dome-forming tool having a dome-shaped void presses the disk of uncured solid polymer clay into a dome embedding the flat padded earring post, without any excess uncured solid polymer clay or unsightly bubbles or holes, and also forms an embedding zone to attach the dome to the earring when they are both cured.

[0079] While the present invention has been disclosed in connection with the presently preferred best mode described herein, it should be understood that the best mode includes words of description and illustration, rather than words of limitation. There may be other embodiments which fall within this spirit and scope of the invention as defined by the claims. Accordingly, no limitations are to be implied or inferred in this invention except as specifically and as explicitly set forth in the claims.

INDUSTRIAL APPLICABILITY

[0080] The present invention is applicable whenever there is a need to securely and quickly attach a flat padded earring post to a cured solid polymer clay earring.
