[0009] It should be acknowledged that the drawings are illustrative and schematic representations. The drawings are provided for illustrative purposes only, with the explicit understanding that they are not intended to limit the scope or meaning of the claims. [Modes for carrying out the invention]

[0010] The following provides a more detailed description of various concepts related to methods, apparatus, and systems for multi-core metal assemblies for eyewear arms, and their implementations. The various concepts described above and discussed in more detail below can be implemented in any of numerous ways, as the described concepts are not limited to specific embodiments. Examples of specific implementations and applications are provided primarily for illustrative purposes.

[0011] I. Overview An eyewear assembly may include two temples. A core metal is integrated into each temple. The temples may be acetate temples and may be translucent so that the core metal is visible when an observer looks at the eyewear assembly. This allows the eyewear assembly to present various aesthetic effects through the core metal. However, the high heat and pressure experienced by the core metal during integration may make it difficult to decorate the core metal integrated into the temple, potentially damaging, destroying, or burning off any decorative components included in the core metal. For example, during manufacturing, the temples may be heated and placed in a mold. The core metal may then be injected or pressed into the temple from the end of the temple. This high heat and pressure applied to the core metal may make it difficult or impossible to decorate the core metal as desired.

[0012] To solve these and other technical problems, this solution relates to a multi-cored core assembly for use in the temples of eyewear assemblies. The multi-cored core assembly may include two cores (e.g., dual cores), namely a base core and an insert core (e.g., a first core and a second core). The base core may be formed from a heat-resistant material such as titanium. The insert core may be inserted into a cavity in the base core. The cavity in the base core may protect and shield the insert core from high heat and / or pressure during manufacturing. Specifically, during manufacturing, the multi-cored core assembly may be injected into the temples of eyewear assemblies at high temperature and pressure without undesiring effects on the insert core. Because the insert core is protected from high heat and temperature, it may be decorated to have, for example, various etchings, markings, gemstones, patterns, textures, etc. These decorations are visible after the manufacturing of the eyewear assembly, which is desirable. Furthermore, the shielding provided by the base core metal allows for the use of softer metals or other materials for the insert core metal, which might otherwise melt, deform, or burn during the manufacturing process without the multi-core metal assemblies described herein. For example, the insert core metal may include or be formed from carbon fiber, horn, ceramic, wood, gold, silver, etc. Because the insert core metal may contain (or be colored differently from) the base core metal, the multi-core metal assemblies may offer contrasting colors not obtainable with conventional core metals used in other eyeglasses.

[0013] Because a multi-cored frame assembly is formed from multiple individual components, the base core can be combined with different insert cores of different appearances to customize the appearance of the multi-cored frame assembly. This offers manufacturing advantages because a single base core can be manufactured while different insert cores can be manufactured to customize the appearance of the multi-cored frame assembly. Manufacturers utilizing the multi-cored frame assemblies described herein can utilize the same base core for multiple styles, models, and brands of eyewear assemblies by simply changing the insert core core according to the style, model, or brand, instead of manufacturing separate pairs of conventional cores for each style, model, or brand of eyeglasses. Because the insert cores are smaller than conventional cores, the multi-cored frame assemblies described herein can reduce costs for manufacturers while simultaneously enabling them to produce eyewear assemblies with aesthetic effects that cannot be provided by conventional eyeglasses.

[0014] II. Exemplary Overview of Eyewear Assemblies Referring next to Figures 1 and 2, the eyewear assembly 100 is shown. The eyewear assembly 100 is configured to be worn by a user (e.g., a human, adult, child, etc.). The eyewear assembly 100 provides the user with aesthetic (e.g., fashionable, etc.) and / or functional (e.g., optical, etc.) benefits. The eyewear assembly 100 may be a pair of glasses, an optical device, a visual aid, a pair of eyeglasses, sports glasses, sunglasses, augmented reality / virtual reality (AR / VR) glasses, etc. The eyewear assembly 100 includes a multi-core assembly 105. As described in more detail herein, the multi-core assembly 105 provides both structural support to the eyewear assembly 100 and aesthetic detail to the eyewear assembly 100.

[0015] The multi-cored metal assembly 105 includes a base cored metal 120 and an insert cored metal 135 is shown. The eyewear assembly 100 may include clear or tinted lenses 150. The lenses 150 may be polarized. The eyewear assembly 100 may be prescription or non-prescription glasses, for example, the lenses 150 may be prescription or non-prescription lenses.

[0016] The eyewear assembly 100 includes a frame 115 (e.g., a rim). The frame 115 may hold the lenses of the eyewear assembly 100. The frame 115 may form a bridge that rests on the wearer's nose. The frame 115 is coupled (e.g., fixed, secured, fastened, etc.) to at least one arm or temple 110 of the eyewear assembly 100. The eyewear assembly 100 includes a first temple 110 and a second temple 110. The frame 115 may be coupled to the first temple 110 and the second temple 110. For example, the first end or side of the frame 115 may be coupled to the first temple 110. The first temple 110 may extend away from the frame 115 to provide a surface that rests on the wearer's ear. The second end or side of the frame 115 may be coupled to the second temple 110. A second temple 110 may extend away from the frame 115 to provide a surface that rests on the wearer's other ear. The frame 115 may be coupled to the temple 110 via a hinge 145 to fold the temple 110 between a retracted position and an extended position. The eyewear assembly 100 may include a first hinge 145 for moving the first temple 110 and a second hinge 145 for moving the second temple 110.

[0017] The temple 110 includes a multi-core assembly 105. Each temple 110 (or just one temple 110) includes a multi-core assembly 105. Each temple 110 may include a multi-core assembly 105 having insert cores 135 of the same or different appearance. The temple 110 may be formed from acetate or integrally formed. The multi-core assembly 105 is placed, positioned, integrated, injected, or laminated within the temple 110. The multi-core assembly 105 includes at least one base core 120. The multi-core assembly 105 includes at least one insert core 135. The base core 120 and the insert core 135 may be joined together. The base core 120 may be formed from titanium, steel, aluminum, etc., and the insert core 135 may be formed from titanium, steel, aluminum, carbon fiber, horn, ceramic, wood, gold, silver, etc.

[0018] The base core 120 includes a body 125. The base core 120 includes an elongated portion 130. The elongated portion 130 may extend from the end of the body 125 along the longitudinal axis 140 of the body 125. The longitudinal axis 140 may be a common longitudinal axis of the multi-core assembly 105, the base core 120, the body 125, the elongated portion 130, or the insert core 135.

[0019] The base core metal 120 and the insert core metal 135 are separate components that are joined together. Because the base core metal 120 and the insert core metal 135 are separate components, the base core metal 120 can be joined with different insert core metals 135 of different appearances to customize the appearance of the multi-core metal assembly. This provides a manufacturing advantage because one single base core metal 120 can be manufactured, while different insert core metals 135 can be manufactured to customize the appearance of the multi-core metal assembly. The insert core metal 135 is inserted, integrated, or positioned into an opening, hole, or cavity in the base core metal 120. The base core metal 120 includes a cavity, recess, slot, or opening inside which the insert core metal 135 is placed, mounted, positioned, inserted, or set. The cavity in the base core metal 120 is molded to fit at least a portion of the outer surface of the insert core metal 135.

[0020] Next, referring to Figures 3 and 4, exploded perspective views of the multi-core assembly 105 are shown. The elongated portion 130 may have a tubular shape, cylindrical shape, rectangular parallelepiped shape, pentagonal prism shape, hexagonal prism shape, octagonal prism shape, etc. The elongated portion 130 may extend outward from the base core 120 along the longitudinal axis 140 from the end, point, or vertex 305 of the base core 120.

[0021] The main body 125 includes at least one cavity 310. The cavity 310 forms a space or region in which at least a portion of the insert core 135 is arranged, placed, positioned, or installed. The cavity 310 may have a tubular shape, cylindrical shape, rectangular parallelepiped shape, pentagonal prism shape, hexagonal prism shape, octagonal prism shape, etc. The cavity 310 may include a bottom surface 315. The bottom surface 315 may form the bottom of the cavity 310. The bottom surface 315 may be flat or smooth. The bottom surface 315 may extend along the longitudinal axis 140. The bottom surface 315 may extend perpendicular to the longitudinal axis 140. The bottom surface 315 may extend in opposite directions perpendicular to the longitudinal axis 140 to an upper edge and a bottom edge having surfaces 320 and 325.

[0022] The main body 125 may include a surface 320 extending from the edge of the bottom surface 315 at a certain angle to the surface of the surface 315. The surface 320 may extend in a direction perpendicular to the longitudinal axis 140. The surface 320 may extend from the surface 315 at a certain angle to the plane formed by the surface 315. The angle may be oblique. The angle may be approximately 45 degrees. The angle may be between 43 and 47 degrees. The angle may be less than 43 degrees. The angle may be greater than 47 degrees. The main body 125 may include a surface 325 extending from the edge of the bottom surface 315 at a certain angle to the plane formed by the bottom surface. The surface 325 may extend in a direction perpendicular to the longitudinal axis 140. The angle may be oblique. The angle may be approximately 45 degrees. The angle may be between 43 and 47 degrees. The angle may be less than 43 degrees. The angle may be greater than 47 degrees.

[0023] The insert core 135 may include a portion 335. The portion 335 may have an outer surface that forms a shape conforming to the internal shape of the cavity 310. For example, the portion 335 may have a flat surface 340 for resting with surface 315 and an angled surface 345 for resting with surfaces 325 and 320 of the cavity 310. The portion 335 may have a tubular shape, a cylindrical shape, a rectangular parallelepiped shape, a pentagonal prism shape, a hexagonal prism shape, an octagonal prism shape, and the like. At least a portion of the insert core 135 may extend outward from the cavity or be visible to an observer from outside the cavity. For example, at least one outer surface may extend outward from the cavity 310 or be visible from outside the cavity. In some embodiments, none of the outer surfaces extend outward from the cavity 310. In some embodiments, the insert core 135 does not extend beyond the upper edge or boundary of the cavity 310 so that the base core 120 protects the insert core 135 during manufacturing.

[0024] Part 335 may include an outer surface 350 opposite the inner surface 340. The outer surface 350 may be located outside the cavity 310 or may be visible from outside the cavity. Part 335 may include an angled surface 355 opposite the surface 345. The outer surface 355 may be located outside the cavity 310 or may be visible from outside the cavity. The angled surface 355 may extend from the surface 350 to each edge of the inner surface 345.

[0025] The main body 125 may include a slot 330. The slot 330 may be a cavity, opening, or space. The slot 330 may be formed on the surface 315 of the cavity 310. The slot 330 may be rectangular in shape. The slot 330 may have a trapezoidal column shape. The portion 335 of the insert core 135 may include a projection 360. The projection 360 may extend outward from the surface 340 of the insert core 135. For example, the projection 360 may extend outward in a direction perpendicular to the longitudinal axis of the insert core 135 (e.g., the longitudinal axis 140).

[0026] The projection 360 may be prism-shaped or trapezoidal. The shape of the projection 360 may conform to the shape of the slot 330. In this regard, the slot 330 may frictionally hold or connect to the projection 360, thereby at least partially connecting the insert core metal 135 to the cavity 310 of the base core metal 120. Thus, during manufacturing, when the multi-core metal assembly 105 is subjected to high heat or pressure, the insert core metal 135 may remain connected to the base core metal 120 via the slot 330 and projection 360, and the insert core metal 135 may not fall out during manufacturing.

[0027] Furthermore, the multi-core metal assembly 105 may include at least one connector 390. The connector 390 may be a cylindrical component such as a screw, bolt, or nail. The connector 390 may be inserted into or through an opening 397 in the body 125. The connector 390 may be inserted into or through an opening 405 in the insert core metal 135. The connector 390 may extend between the opening 397 and the opening 405 to hold the body 125 and the insert core metal 135 together. The connector 390 may connect the insert core metal 135 to the body 125. The openings 397 and 405 may be cylindrical, rectangular, hexagonal, or the like. The openings 397 and 405 may have an axis 365 which may be perpendicular to the axis 140.

[0028] In some embodiments, instead of, or in addition to, bonding the insert core 135 to the base core 120 via the connector 390, an adhesive may bond the base core 120 to the insert core 135. The adhesive (e.g., epoxy, acrylic adhesive, polyvinyl acetate, etc.) may be applied to the cavity 310 and / or slot 330, for example, to all or part of the inner surface of the cavity 310 or slot 330. In some embodiments, the adhesive may be applied to the surface of the insert core 135 before it is inserted into the cavity 310. For example, the adhesive may be applied to surfaces 345 and 340. After the adhesive has cured, the multi-core assembly 105 may be placed inside the temple 110. The adhesive may help hold the insert core 135 inside the base core 120 when the multi-core assembly 105 is injected into the temple 110.

[0029] The insert core 135 may include a pointed end 370. The pointed end 370 may be on the opposite side of the end 395 of the insert core 135. The end 395 may be a flat surface formed by the hexagonal prism shape of the portion 335. The end 395 may be the bottom of the hexagonal prism shape of the portion 335. The pointed end 370 may have two parallel triangular surfaces 375 and 410. The surfaces 375 and 410 may be triangular or notched triangular. The ends or points of the triangles may be connected to the vertex 380 of the pointed end 370. An edge 385 may connect a point, end, or edge of the triangular surface 375 to the vertex 380. An edge 415 may connect a point, end, or edge of the triangular surface 410 to the vertex 380.

[0030] Next, referring to Figures 5 to 8, an insert mandrel 135 attached to the base mandrel 120 is shown. The body 125 of the base mandrel 120 may include an inclined portion 505 and a flat portion 530. The flat portion 530 includes a side surface 535. The side surface 535 may extend along the longitudinal axis 140 from the end 525 of the base mandrel 120 toward the end 520 of the base mandrel 120. The end 520 may be on the opposite side of the end 525. Both the end 520 and the end 525 may be located on or intersect the longitudinal axis 140 of the multi-mandrel assembly 105. The end 520 may be a point, vertex, inclined section, or conical section. The end 525 may be a plane or a surface. The end 525 may be a surface perpendicular to the longitudinal axis 140. The flat portion 530 may extend from the end 525 toward the inclined portion 505. The side surfaces 535 may extend parallel to each other from the end surfaces 525. In this respect, the cross-sectional area of ​​the flat portion 530 may be constant from the end surfaces 525 to the starting point of the inclined portion 505.

[0031] The inclined portion 505 may be a frustum or a converging portion. The inclined portion 505 may have a cross-sectional area that decreases along the longitudinal axis 140 toward the end 520. The inclined portion 505 may include opposing sides 510. The opposing sides 510 may be non-parallel. The opposing sides 510 may approach each other along the longitudinal axis 140 of the multi-mandrel assembly 105 as it moves toward the end 520. The opposing sides 510 may approach each other until they meet at the end 515 of the inclined portion 505. The end 515 may be the cross-sectional area of ​​the base mandrel 120 where the inclined portion 505 ends and the elongated portion 130 begins. The elongated portion 130 may extend from the inclined portion 505 to the end 520. The elongated portion 130 may extend from the end 515 to the end or side 520. The elongated portion 130 may extend along the longitudinal axis 140. The elongated portion 130 may have a constant cross-sectional area (or a decreasing cross-sectional area) from the end 515 to the end 520.

[0032] Referring now to Figure 9, a cross-sectional view of the multi-core assembly 105 along plane AA of Figure 6 is shown. The side surface 535 may have an outer edge extending outward from the bottom surface 905 to the upper end 910 of the base core 120. The side surface 535 may have three outer surfaces forming a trapezoidal surface, as shown in Figure 8. However, the side surface 535 may have any number of surfaces, such as four, five, or six. The side surface 535 may be rounded or smooth and may have an arc, curve, or semicircular shape. The surfaces 325 and 320 may be inclined toward each other as they approach the bottom surface 905 or the slot 330. In this respect, the cross-sectional area of ​​the cavity 310, at least partially defined by the surfaces 325 and 320, may decrease from the upper end 910 toward the bottom surface 905. The insert core 135 includes an inclined surface 345 that rests, contacts, or abuts against the surfaces 325 and 320. Surfaces 355 and 350 may be free or open surfaces. At least portions of surfaces 355 and 350 may not come into contact with or abut any surface or portion of the base core metal 120, such as surface 325 or 320.

[0033] Next, referring to Figures 10-11, the base mandrel 120 is shown. The inclined portion 505 may include a base surface 1005. The base surface 1005 may be flush with or parallel to the base surface 315. Surfaces 315 and 1005 may be a single adjacent surface. The base surface 1005 may extend from the edge of the base surface 315 toward the end 515 or end 520. The base surface 1005 may have a triangular surface. The base surface 1005 may have a notched triangular or trapezoidal shape. The base surface 1005 may include two parallel sides of different lengths, and one parallel side of the triangle may have a continuous edge with the base surface 315. The other parallel side of the triangle may have a continuous edge with the surface 1010 of the inclined portion 505. The base surface 1005 may extend from the continuous edge to the surface 1010 that is continuous with the opposite side of the base surface 1005. The base 1005 may include two non-parallel edges extending between the parallel edges of the base 1005. In some embodiments, the parallel edges of the base 1005 are perpendicular to the longitudinal axis 140 of the multi-core assembly 105.

[0034] The inclined portion 505 may include an inclined surface 1010. The surface 1010 may be a trapezoidal, rectangular, or square-shaped surface. The inclined surface 1010 may extend from a non-parallel side of the base surface 1005. The first inclined surface 1010 may have an edge adjacent to the surface 325. The second inclined surface 1010 may have an edge adjacent to the surface 320. The first inclined surface 1010 may have an edge adjacent to the surface 1005. The first inclined surface 1010 may extend inward from the surface 325 to the surface 1005 toward the longitudinal axis 140. The second inclined surface 1010 may have an edge adjacent to the surface 1005. The first inclined surface 1010 may extend inward from the surface 320 to the surface 1005 toward the longitudinal axis 140.

Method 2500 may include positioning surface 345 on surfaces 325 and 320. Furthermore, method 2500 may include positioning the surfaces 1405, 1410, and 1415 of the pointed end 370 on surfaces 1005, 1105, and 1010 of the cavity 310, respectively.

[0052] Method 2500 may include fixing, coupling, connecting, or joining the insert core 135 to the base core 120. The insert core 135 and the base core 120 may be coupled to each other by friction. The insert core 135 and the base core 120 may be coupled via at least one snap or other connector. For example, Method 2500 may include coupling the insert core 135 to the base core 120 via a connector 390 inserted through an opening 397 in the base core 120 and an opening 405 in the insert core 135. Method 2500 may include forming the opening 397 in the base core 120. Method 2500 may include forming the opening 405 in the insert core 135.

The openings 397 and 405 can be formed separately (e.g., before the insert mandrel 135 is inserted into the base mandrel 120). The openings 397 and 405 can be formed together. For example, after the insert mandrel 135 has been inserted into the base mandrel 120, a drill bit may be drilled through the base mandrel 120 and the insert mandrel 135 to form the openings 397 and 405 simultaneously (together, or one after the other). The openings 397 and 405 can be formed along a common axis 365 which may be perpendicular to the longitudinal axis 140. Method 2500 may include inserting the connector 390 through the openings 397 and 405 to connect the insert mandrel 135 to the base mandrel 120. Method 2500 may include inserting the connector 390 along the axis 365. Openings 397 and 405 can be threaded. The threads of connector 390 can engage with the threads of openings 397 and 405 to connect the base core metal 120 with the insert core metal 135.

The S-shaped mandrel 135 may have the same geometric shape as the one discussed in more detail with reference to Figures 31 and 32. Similarly, the second insert mandrel 135 may have the same geometric shape and configuration as the insert mandrel discussed in more detail with reference to Figures 33 and 34. However, in Figures 44 and 45, the two insert mandrels 135 are positioned on opposite sides of the base mandrel 120. In this regard, the base mandrel 120 may have a cavity 135 into which an insert mandrel 135 can be inserted and positioned. The cavity 135 may be on the opposite side of the base mandrel 120 and may be shaped to receive each insert mandrel 135. The first cavity 135 may have an irregular hexagonal shape (e.g., having an opening that is an irregular hexagonal shape) to accommodate or receive the irregular hexagonal shape of the insert mandrel 135. Similarly, the second cavity 135 may be an S-shaped cavity (e.g., a cavity with an S-shaped opening) to accommodate an S-shaped insert 135. The base 120 may include a surface 4520 around the cavity 135 into which the S-shaped insert 135 is positioned. The surface 4520 may be raised, roughened, or otherwise shaped to provide an aesthetic appearance.

[0062] III. Configuration of an exemplary embodiment This specification includes many specific implementation details, which should be interpreted not as limitations on the scope of what can be claimed, but rather as descriptions of features specific to a particular implementation. Certain features described herein in the context of separate implementations may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may be implemented individually in multiple implementations, or in any appropriate sub-combination. Furthermore, features may be described as acting in a particular combination, and may initially be claimed as such; however, one or more features from a claimed combination may, in some cases, be removed from that combination, and the claimed combination may be directed towards a sub-combination or a variation of a sub-combination.

[0063] As used herein, “approximately,” “generally,” and similar terms are intended to have a broad meaning consistent with the common and accepted usage by those skilled in the art to which the subject matter of this disclosure relates. Those skilled in the art reviewing this disclosure should understand that these terms are intended to allow descriptions of specific features described and claimed without limiting the scope of those features to the precise numerical range provided. Accordingly, these terms should be interpreted as indicating that any substantive or insignificant modification or alteration of the subject matter described and claimed is deemed to fall within the scope of the disclosure as described in the appended claims.

[0064] As used herein, the terms “coupled” and similar terms mean joining two components directly or indirectly to one another. Such joining may be static (e.g., permanent) or movable (e.g., detachable or detachable). Such joining may be achieved by two components, or two components and any additional intermediate components, being formed integrally with one another as a single, unified body, or by attaching two components, or two components and any additional intermediate components, to one another.

[0065] It is important to note that the various system configurations and arrangements shown in the various exemplary implementations are illustrative only and not restrictive in nature. It is desirable that all changes and modifications within the spirit and / or scope of the described implementations be protected. It should be understood that some features may not be necessary, and that implementations lacking various features may also be contemplated within the scope of this disclosure, the scope of which will be defined by the subsequent claims. Where the phrase "a portion" is used, that item may include a portion and / or the entire item unless otherwise stated.

[0066] Furthermore, the term "or," when used to connect a list of elements, is used in its inclusive (and not exclusive) sense within the context of a list of elements. Therefore, it means one, some, or all of the elements in the list. Unless otherwise specified, conjunctions such as "at least one of X, Y, and Z" are understood in the context of commonly used expressions to convey that an item, term, etc., could be X, Y, Z, X and Y, X and Z, Y and Z, or X, Y, and Z (i.e., any combination of X, Y, and Z). Thus, such conjunctions are generally not intended to mean that a particular embodiment contains at least one X, at least one Y, and at least one Z, respectively (unless otherwise indicated).

[0067] Furthermore, the use of value ranges (e.g., W1 to W2) in this specification includes their maximum and minimum values ​​unless otherwise specified (e.g., W1 to W2 includes W1 and W2). Furthermore, value ranges (e.g., W1 to W2) do not necessarily require the inclusion of intermediate values ​​within that range unless otherwise specified (e.g., W1 to W2 may include only W1 and W2).
