[0011] As explained above, this disclosure enables an earring that addresses various technical problems mentioned above. The earring comprises a C-shape portion having a first end portion and a second end portion, where the first end portion and the second end portion are spaced apart from each other to form a gap therebetween. The first end portion hosts a post laterally extending therefrom. The second end portion hosts a catch laterally extending therefrom. The catch is configured to catch the post not over the gap.

[0012] This disclosure is now described more fully with reference to drawings, in which some examples of this disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as necessarily being limited to various examples disclosed herein. Rather, these examples are provided so that this disclosure is thorough and complete, and fully conveys various concepts of this disclosure to skilled persons. Note that like numbers or similar numbering schemes can refer to like or similar elements throughout.

[0013] Various terminology used herein can imply direct or indirect, full or partial, temporary or permanent, action or inaction. For example, when an element is referred to as being "on," "connected" or "coupled" to another element, then the element can be directly on, connected or coupled to the other element or intervening elements can be present, including indirect or direct variants. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.Docket: 15019214-000642 Patent Specification

[0014] Various singular forms "a," "an" and "the" are intended to include various plural forms (e.g., two, three, four, five, six, seven, eight, nine, ten, tens, hundreds, thousands) as well, unless specific context clearly indicates otherwise.

[0015] Various presence verbs "comprises," “includes” or "comprising," “including” when used in this specification, specify a presence of stated features, integers, steps, operations, elements, or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.

[0016] As used herein, a term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of a set of natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances.

[0017] As used herein, a term "or others," "combination", "combinatory," or "combinations thereof" or another conceptually similar terminology refers to all permutations and combinations of listed items preceding that term. For example, "A, B, C, or combinations thereof" is intended to include at least one of: A, B, C, AB, AC, BC, or ABC, and if order is important in a particular context, also BA, CA, CB, CBA, BCA, ACB, BAC, or CAB. Continuing with this example, expressly included are combinations that contain repeats of one or more item or term, such as BB, AAA, AB, BBC, AAABCCCC, CBBAAA, CABABB, and so forth. Skilled persons understand that typically there is no limit on number of items or terms in any combination, unless otherwise contextually apparent.

[0018] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in an art to which this disclosure belongs. Various terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with a meaning in a context of a relevant art and should not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.

[0019] Relative terms such as "below," "lower," "above," and "upper" can be used herein to describe one element's relationship to another element as illustrated in the setDocket: 15019214-000642 Patent Specification of accompanying illustrative drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to an orientation depicted in the set of accompanying illustrative drawings. For example, if a device in the set of accompanying illustrative drawings were turned over, then various elements described as being on a "lower" side of other elements would then be oriented on "upper" sides of other elements. Similarly, if a device in one of illustrative figures were turned over, then various elements described as "below" or "beneath" other elements would then be oriented "above" other elements. Therefore, various example terms "below" and "lower" can encompass both an orientation of above and below.

[0020] As used herein, a term "about" or "substantially" refers to a + / - 10% variation from a nominal value / term. Such variation is always included in any given value / term provided herein, whether or not such variation is specifically referred thereto.

[0021] Although the terms first, second, can be used herein to describe various elements, components, regions, layers, or sections, these elements, components, regions, layers, or sections should not necessarily be limited by such terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from various teachings of this disclosure.

[0022] Features described with respect to certain example examples can be combined and sub-combined in or with various other example examples. Also, different aspects or elements of example examples, as disclosed herein, can be combined and sub-combined in a similar manner as well. Further, some example examples, whether individually or collectively, can be components of a larger system, wherein other procedures can take precedence over or otherwise modify their application. Additionally, a number of steps can be required before, after, or concurrently with example examples, as disclosed herein. Note that any or all methods or processes, at least as disclosed herein, can be at least partially performed via at least one entity in any manner.

[0023] Example examples of this disclosure are described herein with reference to illustrations of idealized examples (and intermediate structures) of this disclosure. As such, variations from various illustrated shapes as a result, for example, of manufacturingDocket: 15019214-000642 Patent Specification techniques or tolerances, are to be expected. Thus, various example examples of this disclosure should not be construed as necessarily limited to various particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing.

[0024] Any or all elements, as disclosed herein, can be formed from a same, structurally continuous piece, such as being unitary or monolithic, or be separately manufactured or connected, such as being an assembly or modules. Any or all elements, as disclosed herein, can be manufactured via any manufacturing processes, whether additive manufacturing, subtractive manufacturing, or other any other types of manufacturing. For example, some manufacturing processes include three dimensional (3D) printing, laser cutting, computer numerical control routing, milling, pressing, stamping, vacuum forming, hydroforming, injection molding, lithography, chiseling, cutting, and so forth.

[0025] Hereby, all issued patents, published patent applications, and non-patent publications that are mentioned or referred to in this specification are herein incorporated by reference in their entirety for all purposes, to a same extent as if each individual issued patent, published patent application, or non-patent publication were specifically and individually indicated to be incorporated by reference. To be even more clear, all incorporations by reference specifically include those incorporated publications as if those specific publications are copied and pasted herein, as if originally included in this disclosure for all purposes of this disclosure. Therefore, any reference to something being disclosed herein includes all subject matter incorporated by reference, as explained above. However, if any disclosures are incorporated herein by reference and such disclosures conflict in part or in whole with this disclosure, then to an extent of the conflict or broader disclosure or broader definition of terms, this disclosure controls. If such disclosures conflict in part or in whole with one another, then to an extent of conflict, the later-dated disclosure controls.

[0026] FIGS. 1 -7 show a plurality of views of an example of an earring having a catch with a closed-shape portion according to this disclosure. In particular, there is an earring 100 (e.g., a hoop earring) comprising a C-shape portion 102 (e.g., a curved segment forming an incomplete circle with two spaced-apart ends). The C-shape portion 102 isDocket: 15019214-000642 Patent Specification defined by a plurality of links 104 that are sequentially attached to each other end-to-end and hosting a plurality of gemstones 106. For example, at least some of the plurality of links 104 may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. The plurality of links 104 has a first end portion 108 and a second end portion 122 such that the first end portion 108 and the second end portion 122 are spaced apart from each other to form a gap (e.g., an air gap) therebetween, as shown in FIG. 6. For example, the gap (e.g., a space between the first and second end portions 108 and 122) may be about 1 inch or less in arcuate or rectilinear length (e.g., about 0.8 inches or less, about 0.6 inches or less). The first end portion 108 hosts a first engagement unit 110 (e.g., a structure configured to facilitate attachment or detachment of the earring 100) comprising a post 112 (e.g., a rigid member configured to pass through a pierced ear). The second end portion 122 hosts a second engagement unit 114 (e.g., a structure configured to facilitate attachment or detachment of the earring 100) comprising a catch 116 configured to catch (e.g., engage and retain) the post 112 not over the gap (e.g., a position where the catch 116 engages the post 112 at a location other than directly across the gap between the ends of the C-shape portion 102).

[0027] As shown in FIGS. 1-7, the C-shape 102 portion avoids hosting any pivots between the first end portion 108 and the second end portion 122. However, the C-shape 102 may host a pivot between the first end portion 108 and the second end portion 122 such that the C-shape may pivot between a C-shape position and a 3-shape position, whether symmetrical or asymmetrical, as shown in FIG. 10. In some cases, the C-shape 102 has a plurality of charms, pendants, or other suitable jewelry elements dangling therefrom, such as from within a lower half of the external side of the C-shape 102 when viewed from a profile view with the C-shape 102 being positioned such that the gap faces skyward. This configuration is technologically advantageous because it enables the distribution of mass along the lower half of the earring 100, which lowers the center of gravity and stabilizes the earring 100 against rotational movement during wear. By concentrating charms or pendants within the lower external arc, the configuration minimizes torque exerted on the earlobe, thereby reducing discomfort and risk of accidental disengagement. The arrangement also enhances the visual appeal by presenting decorative elements in a prominent, unobstructed location, especially whenDocket: 15019214-000642 Patent Specification viewed from the front. Mechanically, the lower placement of dangling elements avoids interference with the closure mechanism and maintains the integrity of the stability triangle formed by the post 112, the catch 116, and the gap. This configuration further allows for modular customization, enabling users to interchange or add jewelry elements without affecting the core function of the earring 100, which may be without taking off the earring 100. The design supports manufacturing efficiency by permitting standardized attachment points for charms, reducing assembly complexity.

[0028] The links 104 are individual elements that are arranged sequentially to collectively form the C-shape 102, with the links 104 being connected end-to-end along the curved path of the C-shape 102. The arrangement of the links 104 creates a continuous, graceful arc, with each link 104 contributing to the overall curvature and structural integrity of the C-shape 102. The links 104 maintain suitable structure and visual continuity throughout the C-shape 102. This configuration allows the earring 100 to elegantly follow the contour of the earlobe.

[0029] The gap between the first end portion 108 and the second end portion 122 geometrically sets the terminal tip separation of the C-shape portion 102. By selecting a gap dimension (e.g., up to about 1 inch, or smaller for compact designs), a designer can tune (i) ear-piercing alignment compensation so that, even if the piercing channel is angled relative to the wearer’s head, the earring 100 closes along a line that does not span the gap and consequently presents generally parallel to the head when facing the wearer face-to-face (e.g., eye-to-eye); (ii) insertion clearance for the lobe, enabling easy insertion / removal without excessive flexure; and (iii) mechanical preload at closure, which stabilizes the earring against rotation, reducing snagging on hair or apparel (safety) and pressure points on the lobe (comfort). Offering wider or narrower C-shapes within a family of designs allows tailoring to ear anatomy and piercing angles, balancing aesthetics (visual width, gemstone reveal) with functional stability (lower rotational moment, improved generally parallel orientation).

[0030] Each of the links 104 functions as a setting and therefore respectively hosts a gemstone 106 (e.g., a diamond, a ruby, a sapphire, a moissanite). As shown in FIGS. 1- 7, each of the links 104 is rigid, tubular, and open on both ends to internally host the gemstone 106 such that the gemstone 106 respectively fills the internal tubular openDocket: 15019214-000642 Patent Specification space and is visible from both ends. However, note that the links 104 may be configured to external host the gemstones 106. As shown in FIGS. 1 -7, the gemstones 106 are a marquise-cut (eye-shaped) gemstones 106. As such, the links 104 are structured to accommodate or simulate such structure and therefore the links 104 operate as settings that are tubular as defined by a pair of outwardly arcuate sidewalls to form an eye-shape and open on both ends. However, note that the gemstones 106 may be shaped differently, which may cause the links 104 to be correspondingly shaped to accommodate or simulate such gemstones 106.

[0031] As shown in FIG. 1 , the gemstones 106 are a marquise-cut (eye-shaped) gemstones 106, which are characterized by their elongated, symmetrical outlines with pointed ends, resembling the shape of an eye or a boat. Such gemstone 106 features a curved profile that tapers smoothly to each tip, creating a visually striking and elegant silhouette. The facets on the surface of the marquise cut are arranged to maximize brilliance and light reflection, often resulting in a sparkling appearance. The distinctive form of this shape adds both sophistication and a sense of length to the overall design. The marquise cut has its unique geometry to allow it to appear larger than other cuts of similar carat weight. As such, some of the gemstones 106 are arranged in a position 118 such that their pointed ends are facing inwards toward the links 104 or other gemstones 106, and some of the gemstones 106 are arranged in a position 120 such that their pointed ends are facing outwards away from the links 104 or other gemstones 106. Alternating the marquise-cut gemstones 106 so that some are oriented inward in the position 118 and others outward in the position 120 achieves (i) mass distribution symmetry along the arc, lowering the tendency of the earring to yaw away from a generally parallel presentation (orientation); (ii) micro-textured airflow and hair deflection, as the alternating tips interrupt continuous strands of hair, reducing snag events (safety); (iii) contact comfort, because inward-facing tips create smooth outer contours while outward-facing tips preserve visual brilliance, reducing sharp edges against skin (comfort); and (iv) aesthetic dynamism, as alternating facet directions produce sparkle changes with head movement, enhancing perceived length and elegance (aesthetics), while providing an uninterrupted view of the gemstones 106 when viewing the wearerDocket: 15019214-000642 Patent Specification face-to-face (e g., eye-to-eye). However, this configuration is not required and all the gemstones 106 may be arranged in the position 118 or the position 120.

[0032] The first end portion 108 hosts the first engagement unit 110 comprising the post 112. For example, the first engagement unit 110 or the post 112 may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. The post 112 is shown to have a circular cross-section, but the post 112 may have a noncircular cross-section.

[0033] The circular cross-section of the post 112 may be technologically advantageous because it provides uniform stress distribution during insertion through the pierced ear, minimizing localized pressure points and reducing the likelihood of tissue irritation. The geometry facilitates smooth rotational movement, allowing the wearer to adjust the earring’s 100 orientation with minimal resistance. The circular cross-section post 112 may be compatible with a wide range of catch 116 mechanisms, including friction-fit, latch, and magnetic closures, thereby enhancing design flexibility. From a manufacturing perspective, circular posts are easier to machine or form with consistent tolerances, improving quality control and reducing production costs. The shape also supports sterilization and cleaning, as there are no sharp corners or recesses where debris can accumulate. In terms of durability, the circular cross-section post 112 may resist bending and deformation under typical loads encountered during wear. The configuration is widely accepted in the jewelry industry, ensuring compatibility with existing standards and user expectations.

[0034] The post 112 may have the non-circular cross-section, such as flat, triangular, square, pentagonal, or any other suitable shape. The non-circular cross-section post 112 may be technologically advantageous because it can provide enhanced mechanical interlocking with the catch 116, improving retention and reducing the risk of accidental disengagement. Shapes such as flat, triangular, or square cross-sections offer increased resistance to rotational slip, maintaining the earring’s 100 intended orientation relative to the wearer’s head. The non-circular post 112 can be tailored to accommodate anatomical variations, such as thicker or irregularly shaped earlobes, by distributing contact forces more evenly. The geometry allows for the integration of ornamental features or branding, adding aesthetic value without compromising function. From a safety perspective, theDocket: 15019214-000642 Patent Specification non-circular post 112 can be designed to minimize sharp edges, reducing the risk of injury during insertion or removal. The configuration supports advanced manufacturing techniques, such as precision casting or Computer Numerical Control (CNC) machining, enabling complex shapes with high repeatability.

[0035] The C-shape 102 may have a central portion and the first engagement unit 110 may have a section 124 extending toward the central portion, past the height of the last link 106 as shown in FIGS. 4-5, with the section 124 functioning as a base and hosting the post 112 such that the post 112 cantileveredly extends from the section 124. As shown in FIGS. 4-5, the section 124 may be positioned at a 12 o’clock position when the C- shape 102 is viewed from a profile view. Such positioning may provide stability and counterbalance to keep the earring 100 positioned generally parallel to the wearer’s head when viewed face-to-face (e g., eye-to-eye), although this positioning is not required and the section 124 may be positioned at other positions, such as 11 o’clock or 1 o’clock. The section 124 that projects toward the central portion provides a cantilever base with higher bending stiffness and torsional resistance for the post 112. This configuration reduces post 112 deflection during insertion and wear, thereby maintaining a repeatable closure geometry (orientation) and minimizing lobe pinch due to misalignment (comfort). The rigid base also reduces accidental disengagement under side loads (safety) and offers a clean visual transition from gemstone settings to the post (aesthetics). As shown, the section 124 is configured as a trapezoidal prism or a trapezoidal cuboid that is internally solid, but this configuration may vary and the section 124 may be shaped as another shape, a cube for example, or be internally hollow. Regardless of shaping or presence / absence of the section 124, this configuration is not required and the section 124 may be omitted such that the post 112 cantileveredly extends from the last link 104 or the section 124 may not extend toward the central portion of the C-shape 102 or the section 124 may not extend past the height of the last link 106 as shown in FIGS. 4-5.

[0036] The first end portion 108 or the first engagement portion 110 hosts the post 112 to be laterally and cantileveredly offset and extending therefrom (e.g., at an angle between about 0 degrees and about 90 degrees), which may be away from the gap, and not extending over the gap (e.g., not spanning). Having the post 112 extend laterally and cantileveredly from the first engagement unit 110, while not spanning the gap, ensuresDocket: 15019214-000642 Patent Specification that closure occurs offset from the lobe midline. This offset yields a triangular stability geometry (see FIG. 6), which self-biases the earring 100 toward a generally parallel orientation with the head. The arrangement reduces friction paths across the lobe (comfort), limits snag lines that would otherwise traverse the gap (safety), and maintains a clean negative space within the C-shape 102, enhancing aesthetics. For example, the post 112 may laterally and cantileveredly extend at about 60 degrees or less or about 45 degrees or less, whether to right or left, as appropriate. Although the post 112 is rectilinear as shown in FIGS. 1-7, this configuration is not required and the post 112 may be non- rectilinear (e.g., arcuate, sinusoidal). The post 112 may have a length of about 1 inch or less, whether rectilinear or non-rectilinear (e.g., arcuate, sinusoidal). The post 112 may be fixedly and cantileveredly attached to the first end portion 108 or the first engagement portion 110, although movable (e.g., pivotal) and cantilevered attachment is possible.

[0037] The second end portion 122 hosts the second engagement section 114 comprising the catch 116. For example, the second engagement section 114 or the catch 116 may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. The catch 116 may be a latch, a magnet, a hook-and-loop, a mating element, or another suitable configuration. Each catch configuration provides distinct technical advantages: a latch offers secure mechanical retention and repeatable closure geometry (orientation, safety); a magnet enables low-force engagement and quick release (comfort, safety); a hook-and-loop or mating element allows adaptive compliance for diverse lobe thicknesses and piercing angles (comfort, orientation). These options support both safety and comfort while allowing aesthetic variation. Note that the catch 116 may be configured to adapt to the cross-sectional shape of the post 112. For example, if the post 112 has the circular cross-section, then the catch 116 may be adapted accordingly. Likewise, if the post 112 has the non-circular cross-section, then the catch 116 may be adapted accordingly.

[0038] The second end portion 122 or the second engagement portion 114 hosts the catch 116 to be laterally and cantileveredly offset and extending therefrom (e.g., at an angle between about 0 degrees and about 90 degrees), which may away from the gap, and not extending over the gap (e.g., not spanning). This lateral and cantilevered extension ensures that the catch engages the post at an offset from the lobe midline,Docket: 15019214-000642 Patent Specification forming a stability triangle that biases the earring toward generally parallel orientation with the head. This arrangement reduces friction paths across the lobe (comfort), limits snag lines that would otherwise traverse the gap (safety), and maintains a clean negative space within the C-shape, enhancing aesthetics. For example, the catch 116 may laterally and cantileveredly extend at about 60 degrees or less or about 45 degrees or less, whether to right or left, as appropriate. Selecting the extension angle allows tuning of the closure force and alignment, optimizing comfort and retention for different ear anatomies and piercing angles. Lower angles reduce insertion torque and improve generally parallel presentation, while higher angles may enhance retention for active wearers.

[0039] Although the catch 116 is shown in FIGS. 1 -7 to be a closed-shape portion configured to catch the post 112 not over the gap, with the closed-shape portion being shaped an eyelet with an oval-shaped aperture, this configuration is not required. For example, the catch 116 may have the closed-shape portion being shaped as an O-shape, a 0-shape, a D-shape, a star-shape, a teardrop shape, a triangular shape, a circular shape, an oval shape, a rectangular shape, a square shape, a pentagonal shape, an octagonal shape, a polygonal shape, a symmetric shape, an asymmetrical shape, or any other suitable shape. Closed-shape catches (e.g., eyelet, O-shape, D-shape, etc.) provide positive axial and radial capture of the post, increasing retention under multidirectional loads (safety) and repeatable alignment at closure (orientation). Shape selection tunes guide chamfering, contact area, and stress concentration, which can lower contact pressure on the post (comfort) and control visual language (delicate vs bold forms) for aesthetics. However, note that the catch 116 may have an open-shape portion such that the catch 116 catches the post 112 via the open-shaped portion. For example, the open-shape portion may be U-shaped, C-shaped, V-shaped, or Y-shaped. Openshape catches (e.g., U-shaped, C-shaped, V-shaped, Y-shaped) allow tool-free sideloading of the post, reducing insertion torque on the lobe (comfort) and enabling quick release in snag scenarios (safety). The partial enclosure still establishes the triangular stability lines that promote generally parallel orientation while preserving a light, airy aesthetic through visible negative space.

[0040] As shown in FIGS. 1 -7, the catch 116 may catch the post 112 at a location that is offset from the direct line spanning the gap between the first and second end portionsDocket: 15019214-000642 Patent Specification108 and 122, such as engaging the post 122 at a position displaced by at least one link 106 or segment along the arc of the C-shape 102. For example, the catch 116 may engage the post 112 at an angle, such as between about 15 degrees and about 60 degrees from the tangent of the C-shape 102 at the gap, so that the engagement occurs away from the gap’s centerline. For example, the catch 116 may engage the post 112 at a location where the projection of the post 112 and catch along an axis perpendicular to the gap does not overlap with the gap itself, such as engaging the post 112 at a position that is visually separated from the gap when viewed in profile. For example, the catch 116 may engage the post at a location that forms a triangle with the gap and the post 112, such as creating a stability triangle with non-zero area, rather than engaging directly across the gap. For example, the catch 116 may engage the post 112 at a location that is at least about 20% of the arc length of the C-shape portion away from the midpoint of the gap, such as engaging the post 112 at a segment removed from the gap segment. For example, the catch 116 may engage the post 112 at a location that is laterally offset by a predetermined distance, such as at least 2 mm, 5 mm, 10 mm, or other distances from the gap’s chord, depending on the design.

[0041] If the catch 116 catches the post 112 not over the gap, then earring 100 is disposed in a closed position. In the closed position, the post 112 may be snugly held or engaged within the catch 112 and the earring 100 can be worn on the ear when the post 112 extends through the ear between the first engagement portion 110 and the second engagement portion 114, whether the ear is of the wearer or a mannequin. For example, the post 112 may be snugly held or engaged within the catch 116 by friction fit, snap fit, detent engagement, magnetic retention, geometric interlock, or other suitable engagement mechanism, such as the catch 116 enveloping, gripping, or clasping the post 112 so that the post 112 remains securely positioned and resists unintended movement or withdrawal during ordinary wear. For example, the engagement may be exemplified by the post 112 being retained with minimal play, such that the wearer experiences reliable closure and the earring 100 maintains its intended orientation and comfort on the ear. For example, in the closed position, the post 112 may extend into or through the catch 116. As shown in FIG. 6, when the catch 116 catches the post 112 not over the gap such that the C-shape is disposed in the closed position, an imaginary triangle is created as formedDocket: 15019214-000642 Patent Specification via a first rectilinear line extending through or along the second engagement portion 114 (including the catch 116), a second rectilinear line extending through or along the first engagement portion 110 (including the post 112), and a third rectilinear line extending over the gap. For example, in FIG. 6, the imaginary triangle may be exemplified by three distinct vertex references: (i) the post line (the second line), which is a rectilinear line extending through or along the post 112 and the first engagement portion 110; (ii) the catch line (the first line), which is a rectilinear line extending through or along the catch 116 and the second engagement portion 114; and (iii) the gap chord (the third line), which is a rectilinear line extending directly over the gap between the first end portion 108 and the second end portion 122. These three lines form the vertices and sides of the triangle, with each vertex corresponding to the location of the post 112, the catch 116, and the gap, respectively. The triangle geometry may be visually identified in the drawing by connecting the endpoints of the post, catch, and gap, thereby illustrating the mechanical bias that maintains the earring’s intended generally parallel orientation to the head. For example, the triangle may be used to exemplify the mechanical advantage that reduces protrusion and enhances comfort during ordinary wear. Therefore, this triangular geometry biases torque vectors produced by gravity and head motion so the earring settles generally parallel to the wearer’s head (orientation). By preventing over-gap closure, the design reduces protrusion beyond the cheek-plane, lowering snag incidence on hair / clothing (safety), decreasing contact shear at the lobe (comfort), and delivering a clean frontal presentation with continuous gemstone arc (aesthetics). When the earring 100 is worn, the C-shape 102 is resultantly oriented generally parallel to the head of the wearer or the mannequin. In contrast, if the catch 116 does not catch the post 112 not over the gap, then the C-shape is disposed in an open position. In the open position, the earring 100 can be put on or removed from the ear.

[0042] The catch 116 may be pivotally or fixedly attached to the second end portion 122 or the second engagement portion 114. A pivotally attached catch 116 provides compliance during closure to accommodate piercing angle variance, improving orientation and comfort; a fixedly attached catch 116 yields maximum retention and predictable geometry under dynamic loads (safety) with crisp visual continuityDocket: 15019214-000642 Patent Specification(aesthetics). Both are contemplated and can be selected per wearer anatomy and use case.

[0043] The catch 116 may be configured to be moved (e.g., pivoted or swiveled toward or away from the post 112 or opposing end portion) to catch the post 112 not over the gap. For example, the catch 116 may be manually moved to an engagement position or remain or persist in the engagement position, or may be manually moved to a nonengagement position or remain or persist in the non-engagement position based on a spring mechanism, a hinge mechanism, or be freely moving (e.g., rotating, pivoting, sliding), any of which may be internal or external to the C-shape 102 (e.g., one of the links 106). For example, the spring mechanism may be technologically advantageous because it enables automatic engagement or disengagement of the catch 116, such as biasing the catch 116 toward a closed position for secure retention or toward an open position for rapid removal. For example, the hinge mechanism may be technologically advantageous because it allows the catch 116 to pivot or rotate, facilitating alignment with the post 112 and accommodating anatomical variation, such as different ear lobe thicknesses or piercing angles. For example, the freely moving mechanism may be technologically advantageous because it enables multi-directional adjustment, such as sliding or rotating the catch 116 to self-index with the post 112, thereby reducing insertion force and improving comfort for the wearer. Each mechanism may be selected to optimize ease of use, retention reliability, and adaptability to wearer anatomy or use scenario.

[0044] For example, the spring mechanism may include a spring, such as a helical spring, a butterfly spring, a torsion spring, a compression spring, an extension spring, a spiral spring (e.g., a clock spring), a leaf spring, a cantilever beam spring, a wave spring, or any other suitable spring. The spring types may be implemented to provide specific mechanical advantages. For example, a torsion spring may be positioned to bias the catch 116 rotationally, enabling snap engagement and controlled release. For example, the leaf spring may be integrated into the catch 116 assembly to provide linear or angular compliance, supporting gentle closure and reducing pressure on the earlobe. For example, the wave spring may be used to minimize axial space while delivering consistent preload for retention. For example, a cantilever beam spring may be configured to flex upon engagement, distributing forces evenly and enhancing comfort. For example, anDocket: 15019214-000642 Patent Specification extension spring may be attached to the catch 116 to enable stretching and retraction during closure. For example, a spiral spring (e.g., a clock spring) may be used to provide rotational bias and controlled movement. Each spring mechanism may be selected based on desired retention force, range of motion, durability, and aesthetic requirements, and may be combined or substituted as appropriate for specific embodiments.

[0045] For example, the spring mechanism may be configured such that its default state is either an engagement position or a non-engagement position. In a first use case, the spring biases the catch 116 toward the engagement position, so that when no external force is applied, the catch 116 automatically retains the post 112, ensuring secure closure and retention during ordinary wear. The wearer applies force to overcome the spring bias, moving the catch to a non-engagement position for insertion or removal, after which the spring returns the catch 116 to the engagement position. In a second use case, the spring biases the catch 116 toward the non-engagement position, so that when no external force is applied, the catch 116 remains open or disengaged from the post 112. The wearer applies force to move the catch 116 into the engagement position, and the spring returns the catch 116 to the non-engagement position upon release. This configuration may be technologically advantageous for facilitating rapid donning or removal, or for designs where the catch should not engage unless intentionally actuated. In both cases, the spring may be selected from a group containing helical, torsion, leaf, wave, cantilever beam, extension, or spiral springs, and may be tuned for desired retention force, range of motion, and user comfort. The default position may be determined by the orientation, mounting, and preloading of the spring within the catch 116, and may be further adjusted by the geometry of the engagement surfaces. Each example supports adaptive compliance for anatomical variation and piercing angle, and may be visually concealed within the earring 100 structure to preserve aesthetics. As such, the spring mechanism may be configured to maintain closure reliability under dynamic loads encountered during ordinary wear, while permitting tool-free operation by the wearer.

[0046] For example, the hinge mechanism may include a hinge, such as a butterfly hinge, a barrel hinge, a knuckle hinge, a pivot-sleeve hinge, a living hinge, a flexure hinge, a detent hinge, or another suitable hinge. The hinge type selected may be implemented to provide distinct movement characteristics. For example, the butterfly hinge may beDocket: 15019214-000642 Patent Specification used to enable symmetrical opening and closing of the catch 116, supporting bilateral engagement. For example, the barrel hinge may provide robust rotational movement with high durability, suitable for repeated use. For example, the knuckle hinge may offer segmented movement and secure positioning in multiple states. For example, the pivotsleeve hinge may allow smooth rotation with minimal friction, enhancing user comfort. For example, the living hinge may be formed from a single piece of flexible material, supporting repeated bending without mechanical failure. For example, the flexure hinge may be designed for precise angular movement and compliance. For example, the detent hinge may include a locking feature to secure the catch 116 in open or closed positions. Each hinge mechanism is selected based on desired range of motion, retention force, durability, and aesthetic requirements, and may be combined or substituted as appropriate.

[0047] Freeform movement may be enabled by configuring the catch 116 to rotate, pivot, or slide relative to its respective end portion without the constraint of a fixed axis or track. For example, the catch 116 may be mounted on a ball-and-socket joint, allowing multi-directional movement to align with the post during closure. Freeform movement supports adaptive engagement, enabling the earring 100 to self-index and maintain generally parallel orientation regardless of ear lobe thickness or piercing angle. This approach reduces insertion force, enhances comfort, and minimizes accidental disengagement. The freeform mechanism may be visually concealed within the earring 100 structure to preserve a minimalist aesthetic. As such, the freeform movement may be designed to maintain the stability triangle geometry and robust retention under dynamic loads.

[0048] The post 112 may be configured to be moved (e.g., pivoted or swiveled toward or away from the catch 116 or opposing end portion) for the catch 116 to catch the post 112 not over the gap. This configuration enables the wearer to adjust the post 112 position during closure, accommodating variations in ear lobe thickness and piercing angle. Movability of the post 112 allows for fine alignment with the catch 116, reducing insertion force and improving comfort. It also enhances retention by allowing the post 112 to selfindex into the catch 116, minimizing accidental disengagement and supporting generallyDocket: 15019214-000642 Patent Specification parallel orientation of the earring relative to the head. This flexibility is particularly advantageous for users with non-standard piercings or anatomical differences.

[0049] The first end portion 108 may be configured to be moved (e.g., pivoted or swiveled toward or away from the catch 116 or opposing end portion) towards the second end portion 122 or vice versa to enable the catch 116 to catch the post 112 not over the gap. For example, the first end portion 108 may be configured to be moved towards the second end portion 122 by squeezing the C-shape 102 at the first end portion 108 and the second end portion 122 toward each other, or the second end portion 122 may be configured to be moved towards the first end portion 108 by squeezing the C-shape 102 at the first end portion 108 and the second end portion 122 toward each other. Temporary squeezing of the first and second end portions 108 and 122 during donning creates a controlled elastic deformation of the C-shape 102. This improves self-alignment of the post-catch interface (orientation), reduces peak forces transmitted to the lobe (comfort), and lowers snag risk by shortening exposed edges during manipulation (safety), while preserving the visual arc upon release (aesthetics).

[0050] Allowing controlled movement of the catch 116 and / or post 112 facilitates low- force engagement that self-indexes the closure point, reducing insertion effort (comfort), preserving generally parallel presentation despite piercing angle variability (orientation), and minimizing accidental disengagement during hair or clothing contact (safety). The motion path can be visually concealed to maintain a minimalist aesthetic.

[0051] The first end portion 108 or the first engagement portion 110 may be configured to be stationary to enable the catch 116 to catch the post 112 not over the gap. A stationary engagement unit simplifies mechanics and yields repeatable geometry (orientation, safety). A movable engagement unit provides adaptive compliance for diverse lobe thicknesses and piercing angles (comfort) and supports design variants (hidden kinematics) to achieve desired aesthetics.

[0052] The second end portion 122 or the second engagement portion 114 may be configured to be moved (e.g., pivoted or swiveled toward or away from the post 112 or opposing end portion) towards the first end portion 108 or the first engagement portion 110 to enable the catch 116 to catch the post 110 not over the gap. For example, the second engagement portion 114 may have a pivot or a pair of internal outwardly facingDocket: 15019214-000642 Patent Specification horns and the last link 106 may have a pair of internal apertures receiving the pair of internal outwardly facing horns to enable such pivoting, or vice versa. This configuration allows the catch 116 to pivot relative to the C-shape 102, facilitating easier engagement with the post 112 regardless of the wearer’s ear anatomy or piercing angle. The pivot or horn / aperture mechanism provides mechanical compliance, reducing stress on the earlobe during closure and removal. It also improves the reliability of the closure by allowing the catch 116 to align naturally with the post 112, enhancing both comfort and retention. Additionally, this design supports manufacturing flexibility and durability by distributing mechanical loads across multiple contact points.

[0053] The second end portion 122 or the second engagement portion 114 may be configured to be stationary to enable the catch 116 to catch the post 112 not over the gap. The stationary catch 116 provides a fixed reference point for closure, simplifying the mechanics and ensuring repeatable alignment of the post 112 and the catch 116. This enhances the predictability of the closure, reduces the risk of accidental disengagement, and supports robust retention under dynamic loads. The stationary configuration also streamlines manufacturing and assembly, and can improve the aesthetic continuity of the earring by maintaining a consistent visual profile.

[0054] The post 112 may have a section hosting a depression (e.g., a notch) or a projection (e.g., a bump) that engages the catch 116 not over the gap. For example, the section or the post 112 with the section may be configured as an L-shape, a J-shape, a hook shape, or another suitable shape. A local depression (notch) or projection (bump) on the post provides detent-style retention that resists axial withdrawal and rotational slip (safety) while establishing a repeatable stop position (orientation). The micro-features distribute contact, lowering pressure on the lobe (comfort) and enabling subtle ornamental detailing (aesthetics).

[0055] FIG. 8 shows a frontal face-to-face view of an example of a wearer wearing an earring having a catch with a closed-shape portion according to this disclosure. FIG. 9 shows a profile view of an example of a wearer wearing an earring having a catch with a closed-shape portion according to this disclosure. In particular, a wearer 200 wears the earrings 100 on the right ear and the left ear, such that each of the earrings 100 is worn generally parallel to the head of the wearer or generally parallel to each other. ThisDocket: 15019214-000642 Patent Specification modality of wearing each of the earrings 100 is enabled to present in a way that minimizes getting caught on hair, clothing, fingers, or headgear of a wearer thereof, while being configured to be configured to be worn generally parallel to a head of a wearer when an observer faces the head of the wearer face-to-face (e.g., eye-to-eye). For example, this generally parallel orientation reduces forward projection that commonly causes hair entrapment and garment catching (safety), minimizes torque on the lobe to prevent soreness (comfort), maintains consistent frontal symmetry (orientation), and showcases the gemstones within a coherent arc (aesthetics).

[0056] As shown in FIG. 8, the earring 100 may be worn generally parallel to the head of the wearer 200 or to another earring 100 as, for example, an orientation in which a primary plane, arc, or longitudinal axis of the earring 100 may be disposed at an angle within about 0 degrees to about 10 degrees (e.g., about 0 degrees to about 5 degrees, about 0 degrees to about 2 degrees) relative to a reference plane of the wearer’s 200 head, cheek, or jaw when the earring 100 is worn in its intended position. For example, the longitudinal axis of a C-shape 102 may be exemplified as an imaginary line or curve that extends along the central arc of the C-shape 102, following the path equidistant from the inner and outer edges, and connecting the first end portion 108 to the second end portion 122. For example, the earring 100 may be considered to be worn generally parallel when, during ordinary wear, the visible arc, body, or gemstone arrangement is aligned such that its plane or curve is within about 0 degrees to about 10 degrees of the plane tangential to the surface of the wearer’s 200 head adjacent to the ear. For example, generally parallel orientation may be achieved by configuring the post 112 and the catch 116 to engage at an offset location that biases the earring 100 to settle within this angular range. For example, generally parallel orientation may be exemplified by the earring 100 presenting a continuous arc of decorative elements that faces forward when the wearer 200 is frontally viewed face-to-face (e.g., eye-to-eye), and by the earring 100 minimizing protrusion beyond the cheek-plane. Skilled persons understand that generally parallel orientation may be achieved by any combination of the post 122, the catch 116, the C- shape 102, or other component configurations described herein, provided the resulting angle is within the specified or suitable range.Docket: 15019214-000642 Patent Specification

[0057] FIGS. 10 through 16 show a plurality of views of an example of an earring having a catch with an open-shape portion according to this disclosure. In particular, an earring 300 has a body 302 defined by a first segment 304, a second segment 306, and a pivot 308 pivotally attached the first segment 304 to the second segment 306 or vice versa. For example, the first segment or the second segment 306 may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. The first segment 304 and the second 306 has a plurality of slots 310 hosting a plurality of gemstones 312. The body 302 has a first end portion 320 disposed at the first segment 304. The body 302 has a second end portion 314 disposed at the second segment 306. The first end portion 320 and the second end portion 314 are spaced apart from each other to form a gap therebetween. The first end portion 320 has a post 322 cantileveredly and laterally offset and extending away therefrom. The second end portion 314 has a catch 316 cantileveredly and laterally offset and extending therefrom. The catch 316 has a slot 318 configured to receive the post 322 not over the gap. Although the earring 300 is similar to the earring 100, and some, many, most, or all features of the earring 100 can be adapted or applied to the earring 300, note that the earring 300 differs from the earring 100 in several ways.

[0058] First, the body 302 is pivotable between a closed position and an open position, as enabled via the pivot 308 and the first segment 304 or the second segment 306 pivoting relative to each other about the pivot 308. For example, the pivot 308 may be a rectilinear pin, an arcuate pin, a sinusoidal pin, or any other suitable pin. For example, the pin may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. The body 302 may internally contain a spring mechanism to close or persist the closed position or to open or persist the open position. In the closed position, the body 302 has a C-shape, similar to the earring 100. In the closed position, the gap (e.g., a space between the first and second end portions 320 and 314) may be, for example, about 1 inch or less in arcuate or rectilinear length (e.g., about 0.8 inches or less, about 0.6 inches or less). As such, in the closed position, the earring 300 may be worn on the ear, when the pivot 322 extends through the ear, similar to the earring 100. In the open position, the body 302 may have a 3-shape, which allows the earring 300 to be put on or attached to the ear, similar to the earring 100. In the open position, the gapDocket: 15019214-000642 Patent Specification may be about 5 inches or less in arcuate or rectilinear length (e.g., about 4 inches or less, about 3 inches or less). Note that offering wider or narrower C-shapes, whether within the open-position or the closed-position, within a family of designs allows tailoring to ear anatomy and piercing angles, balancing aesthetics (visual width, gemstone reveal) with functional stability (lower rotational moment, improved generally parallel orientation).

[0059] In some cases, whether on the first segment 304 or the second segment 306, the body 302 has a plurality of charms, pendants, or other suitable jewelry elements dangling therefrom, such as from within a lower half of the external side of the body 302when viewed from a profile view with the body 302 being positioned such that the gap faces skyward. This configuration is technologically advantageous because it enables the distribution of mass along the lower half of the earring 300, which lowers the center of gravity and stabilizes the earring 300 against rotational movement during wear. By concentrating charms or pendants within the lower external arc, the configuration minimizes torque exerted on the earlobe, thereby reducing discomfort and risk of accidental disengagement. The arrangement also enhances the visual appeal by presenting decorative elements in a prominent, unobstructed location, especially when viewed from the front. Mechanically, the lower placement of dangling elements avoids interference with the closure mechanism and maintains the integrity of the stability triangle formed by the post 322, the catch 316, and the gap. This configuration further allows for modular customization, enabling users to interchange or add jewelry elements without affecting the core function of the earring 300, which may be without taking off the earring 300. The design supports manufacturing efficiency by permitting standardized attachment points for charms, reducing assembly complexity.

[0060] Second, the body 302 hosts the slots 310 radially and disposed along the outer side in a pattern arrangement on each of the first segment 304 and the second segment 306 between the first end portion 320 and the second end portion 314. Similar to the earring 100, the slots 312 function as a plurality of settings (e.g., oval cross-section, circular cross-section, polygonal cross-section, symmetrical cross-section, asymmetrical cross-section) for the gemstones 312. However, unlike the earring 100, the slots are wells and are only open on one side (outer) for the gemstones 312 to face outward for externalDocket: 15019214-000642 Patent Specification visibility when the earring 300 is inspected or worn. However, note that this configuration is not required and the slots may be open on both sides (outer and inner).

[0061] Third, unlike the earring 100, the post 322 is arcuate, but can be rectilinear. When arcuate, the post 322 conforms more closely to the natural curvature of the earlobe, distributing pressure evenly and reducing localized discomfort. This shape also facilitates easier insertion and removal, especially for thicker or irregular lobes. The arcuate geometry can help maintain the generally parallel orientation of the earring relative to the head, improving both comfort and aesthetics. Alternatively, the rectilinear post 322 may be preferred for certain manufacturing processes or design aesthetics, offering flexibility in product variants.

[0062] The post 322 may be laterally and cantileveredly extending from the first end portion 320 (e.g., at an angle between about 0 degrees and about 90 degrees), which may be away from the gap, and not extending over the gap (e.g., not spanning). This arrangement ensures that the closure occurs offset from the lobe midline, forming a stability triangle that biases the earring 100 toward generally parallel orientation with the head. It reduces friction and pressure on the lobe, limits snagging risks, and maintains a visually clean negative space within the arc formed by the body 302. The cantilevered extension also allows for easier engagement and disengagement of the catch, improving user experience and safety. For example, the post 322 may laterally and cantileveredly extend at about 60 degrees or less or about 45 degrees or less, whether to right or left, as appropriate. Note that the post 322 may have a section hosting a depression (e.g., a notch) or a projection (e.g., a bump) that engages the catch 316 not over the gap. For example, the section or the post 322 with the section may be configured as an L-shape, a J-shape, a hook shape, or another suitable shape. Shaping the post as an L, J, or hook, for example, provides mechanical interlocking with the catch 316, enhancing retention and reducing the likelihood of accidental disengagement. These shapes can also facilitate easier alignment during closure, improving comfort and usability. The geometric features distribute mechanical loads, reducing wear and tear on both the post 322 and the catch 316, and can be tailored for aesthetic appeal or functional requirements.

[0063] The circular cross-section of the post 322 may be technologically advantageous because it provides uniform stress distribution during insertion through theDocket: 15019214-000642 Patent Specification pierced ear, minimizing localized pressure points and reducing the likelihood of tissue irritation. The geometry facilitates smooth rotational movement, allowing the wearer to adjust the earring’s 300 orientation with minimal resistance. The circular cross-section post 322 may be compatible with a wide range of catch 316 mechanisms, including friction-fit, latch, and magnetic closures, thereby enhancing design flexibility. From a manufacturing perspective, circular posts are easier to machine or form with consistent tolerances, improving quality control and reducing production costs. The shape also supports sterilization and cleaning, as there are no sharp corners or recesses where debris can accumulate. In terms of durability, the circular cross-section post 322 may resist bending and deformation under typical loads encountered during wear. The configuration is widely accepted in the jewelry industry, ensuring compatibility with existing standards and user expectations.

[0064] The post 322 may have the non-circular cross-section, such as flat, triangular, square, pentagonal, or any other suitable shape. The non-circular cross-section post 322 may be technologically advantageous because it can provide enhanced mechanical interlocking with the catch 316, improving retention and reducing the risk of accidental disengagement. Shapes such as flat, triangular, or square cross-sections offer increased resistance to rotational slip, maintaining the earring’s 300 intended orientation relative to the wearer’s head. The non-circular post 322 can be tailored to accommodate anatomical variations, such as thicker or irregularly shaped earlobes, by distributing contact forces more evenly. The geometry allows for the integration of ornamental features or branding, adding aesthetic value without compromising function. From a safety perspective, the non-circular post 322 can be designed to minimize sharp edges, reducing the risk of injury during insertion or removal. The configuration supports advanced manufacturing techniques, such as precision casting or CNC machining, enabling complex shapes with high repeatability.

[0065] Fourth, unlike the earring 100, the catch 316 has the open-shape slot 318. As shown in FIGS. 10-16, the open-shape slot 318 is U-shaped, but can be C-shaped, V- shaped, Y-shaped, or any other suitable shape. However, this configuration is not required and the slot 318 can be closed-shape, similar to the earring 100. For example, the slot 318 may be shaped as an O-shape, a 0-shape, a D-shape, a star-shape, aDocket: 15019214-000642 Patent Specification teardrop shape, a triangular shape, a circular shape, an oval shape, a rectangular shape, a square shape, a pentagonal shape, an octagonal shape, a polygonal shape, a symmetric shape, an asymmetrical shape, or any other suitable shape.

[0066] As shown in FIGS. 8-16, the catch 316 may catch the post 322 at a location that is offset from the direct line spanning the gap between the first and second end portions 320 and 314, such as engaging the post 322 at a position displaced by an equivalent of at least one link 106 or segment along the arc of the C-shape 102 of the earring 100. For example, the catch 316 may engage the post 322 at an angle, such as between about 15 degrees and about 60 degrees from the tangent of the body 302 at the gap, so that the engagement occurs away from the gap’s centerline. For example, the catch 316 may engage the post 322 at a location where the projection of the post 322 and catch along an axis perpendicular to the gap does not overlap with the gap itself, such as engaging the post 322 at a position that is visually separated from the gap when viewed in profile. For example, the catch 316 may engage the post at a location that forms a triangle with the gap and the post 322, such as creating a stability triangle with non-zero area, rather than engaging directly across the gap. For example, the catch 316 may engage the post 322 at a location that is at least about 20% of the arc length of the C- shape portion away from the midpoint of the gap, such as engaging the post 322 at a segment removed from the gap segment. For example, the catch 316 may engage the post 322 at a location that is laterally offset by a predetermined distance, such as at least 2 mm, 5 mm, 10 mm, or other distances from the gap’s chord, depending on the design.

[0067] Fifth, unlike the earring 100, the catch 316 is a bar or a plate. For example, the bar or the plate may constitute gold, silver, platinum, copper, zinc, brass, or other metals, alloys, or suitable materials. A bar or plate catch 316 provides a broad contact surface for engaging the post 322, distributing closure forces and reducing localized pressure on the earlobe. This design enhances comfort, increases retention reliability, and supports a variety of aesthetic styles. The bar or plate can be manufactured in different thicknesses and shapes, allowing for customization and improved durability. The bar or the plate of the catch 316 laterally and cantileveredly extends from the second end portion 314 (e.g., at an angle between about 0 degrees and about 90 degrees), which may away from the gap, and not extending over the gap (e.g., not spanning). This configuration ensures thatDocket: 15019214-000642 Patent Specification the catch 316 engages the post 322 at an optimal angle for secure closure and easy release. The cantilevered extension allows for mechanical flexibility, accommodating different ear shapes and piercing angles. It also maintains the stability triangle for generally parallel orientation, reduces snagging risk, and supports a streamlined visual profile. For example, the bar or the plate of the catch 316 may laterally and canti levered ly extend at about 60 degrees or less or about 45 degrees or less, whether to right or left, as appropriate.

[0068] Similar to the earring 100, if the catch 316 catches the post 322 not over the gap, then earring 300 is disposed in a closed position. In the closed position, the post 322 may be snugly held or engaged within the catch 316 and the earring 300 can be worn on the ear when the post 322 extends through the ear between the first end portion 320 and the second end portion 314, whether the ear is of the wearer or a mannequin. For example, in the closed position, the post 322 may extend into or through the catch 316. For example, the post 322 may be snugly held or engaged within the catch 316 by friction fit, snap fit, detent engagement, magnetic retention, geometric interlock, or other suitable engagement mechanism, such as the catch 316 enveloping, gripping, or clasping the post 322 so that the post 322 remains securely positioned and resists unintended movement or withdrawal during ordinary wear. For example, the engagement may be exemplified by the post 322 being retained with minimal play, such that the wearer experiences reliable closure and the earring 300 maintains its intended orientation and comfort on the ear. As shown in FIG. 15, when the catch 316 catches the post 322 not over the gap such that the body 302 is disposed in the closed position, an imaginary triangle is created as formed via a first rectilinear line extending through or along the post 322, a second rectilinear line extending through or along the catch 316, and a third rectilinear line extending over the gap. For example, in FIG. 15, the imaginary triangle may be exemplified by three distinct vertex references: (i) the post line (the first line), which is a rectilinear line extending through or along the post 322 and the first end portion 320; (ii) the catch line (the second line), which is a rectilinear line extending through or along the catch 316 and the second end portion 314; and (iii) the gap chord (the third line), which is a rectilinear line extending directly over the gap between the first end portion 320 and the second end portion 314. These three lines form the vertices and sides of the triangle, with each vertexDocket: 15019214-000642 Patent Specification corresponding to the location of the post 322, the catch 316, and the gap, respectively. The triangle geometry may be visually identified in the drawing by connecting the endpoints of the post, catch, and gap, thereby illustrating the mechanical bias that maintains the earring’s intended generally parallel orientation to the head. For example, the triangle may be used to exemplify the mechanical advantage that reduces protrusion and enhances comfort during ordinary wear. Therefore, this triangular geometry stabilizes the earring 300 against rotational forces, ensuring that it remains generally parallel to the head regardless of piercing angle or ear anatomy. It minimizes protrusion, reducing the risk of snagging on hair or clothing, and distributes mechanical loads for improved comfort. The generally parallel orientation also enhances the visual presentation of the gemstones and overall earring design. As such, when the earring 300 is worn, the body 302 is resultantly oriented generally parallel to the head of the wearer or the mannequin. In contrast, if the catch 316 does not catch the post 322 not over the gap, then the body 302 is disposed in an open position. In the open position, the earring 300 can be put on or removed from the ear.

[0069] Similar to the earring 100, the catch 316 may be movable (e.g., pivoting, swiveling) or fixedly attached to the second end portion 314. The movably attached catch 316 allows for dynamic alignment during closure, accommodating anatomical differences and improving comfort. A fixed attachment provides robust retention and consistent closure geometry, enhancing safety and durability. Both options support manufacturing flexibility and can be selected based on user preference or design requirements.

[0070] Similar to the earring 100, the catch 316 may be configured to be moved (e.g., pivoted or swiveled toward or away from the post 322 or opposing end portion) to catch the post 322 not over the gap. Movability of the catch 316 enables easier engagement with the post 322, accommodating variations in ear anatomy and piercing location. It reduces closure force, improves comfort, and allows for self-indexing of the closure, minimizing accidental disengagement. This flexibility supports a wider range of wearer anatomies and enhances overall usability.

[0071] For example, the catch 316 may be manually moved to an engagement position or remain or persist in the engagement position, or may be manually moved to a nonengagement position or remain or persist in the non-engagement position based on aDocket: 15019214-000642 Patent Specification spring mechanism, a hinge mechanism, or be freely moving (e.g., rotating, pivoting, sliding), any of which may be internal or external to the body 302 (e.g., one of the segment 304 or 306). For example, the spring mechanism may be technologically advantageous because it enables automatic engagement or disengagement of the catch 316, such as biasing the catch 316 toward a closed position for secure retention or toward an open position for rapid removal. For example, the hinge mechanism may be technologically advantageous because it allows the catch 316 to pivot or rotate, facilitating alignment with the post 322 and accommodating anatomical variation, such as different ear lobe thicknesses or piercing angles. For example, the freely moving mechanism may be technologically advantageous because it enables multi-directional adjustment, such as sliding or rotating the catch 316 to self-index with the post 322, thereby reducing insertion force and improving comfort for the wearer. Each mechanism may be selected to optimize ease of use, retention reliability, and adaptability to wearer anatomy or use scenario.

[0072] For example, the spring mechanism may include a spring, such as a helical spring, a butterfly spring, a torsion spring, a compression spring, an extension spring, a spiral spring (e.g., a clock spring), a leaf spring, a cantilever beam spring, a wave spring, or any other suitable spring. The spring types may be implemented to provide specific mechanical advantages. For example, a torsion spring may be positioned to bias the catch 316 rotationally, enabling snap engagement and controlled release. For example, the leaf spring may be integrated into the catch 316 assembly to provide linear or angular compliance, supporting gentle closure and reducing pressure on the earlobe. For example, the wave spring may be used to minimize axial space while delivering consistent preload for retention. For example, a cantilever beam spring may be configured to flex upon engagement, distributing forces evenly and enhancing comfort. For example, an extension spring may be attached to the catch 316 to enable stretching and retraction during closure. For example, a spiral spring (e.g., a clock spring) may be used to provide rotational bias and controlled movement. Each spring mechanism may be selected based on desired retention force, range of motion, durability, and aesthetic requirements, and may be combined or substituted as appropriate for specific embodiments.

[0073] For example, the spring mechanism may be configured such that its default state is either an engagement position or a non-engagement position. In a first use case,Docket: 15019214-000642 Patent Specification the spring biases the catch 316 toward the engagement position, so that when no external force is applied, the catch 316 automatically retains the post 322, ensuring secure closure and retention during ordinary wear. The wearer applies force to overcome the spring bias, moving the catch to a non-engagement position for insertion or removal, after which the spring returns the catch 316 to the engagement position. In a second use case, the spring biases the catch 316 toward the non-engagement position, so that when no external force is applied, the catch 316 remains open or disengaged from the post 322. The wearer applies force to move the catch 316 into the engagement position, and the spring returns the catch 316 to the non-engagement position upon release. This configuration may be technologically advantageous for facilitating rapid donning or removal, or for designs where the catch should not engage unless intentionally actuated. In both cases, the spring may be selected from a group containing helical, torsion, leaf, wave, cantilever beam, extension, or spiral springs, and may be tuned for desired retention force, range of motion, and user comfort. The default position may be determined by the orientation, mounting, and preloading of the spring within the catch 316, and may be further adjusted by the geometry of the engagement surfaces. Each example supports adaptive compliance for anatomical variation and piercing angle, and may be visually concealed within the earring 300 structure to preserve aesthetics. As such, the spring mechanism may be configured to maintain closure reliability under dynamic loads encountered during ordinary wear, while permitting tool-free operation by the wearer.

[0074] For example, the hinge mechanism may include a hinge, such as a butterfly hinge, a barrel hinge, a knuckle hinge, a pivot-sleeve hinge, a living hinge, a flexure hinge, a detent hinge, or another suitable hinge. The hinge type selected may be implemented to provide distinct movement characteristics. For example, the butterfly hinge may be used to enable symmetrical opening and closing of the catch 316, supporting bilateral engagement. For example, the barrel hinge may provide robust rotational movement with high durability, suitable for repeated use. For example, the knuckle hinge may offer segmented movement and secure positioning in multiple states. For example, the pivotsleeve hinge may allow smooth rotation with minimal friction, enhancing user comfort. For example, the living hinge may be formed from a single piece of flexible material, supporting repeated bending without mechanical failure. For example, the flexure hingeDocket: 15019214-000642 Patent Specification may be designed for precise angular movement and compliance. For example, the detent hinge may include a locking feature to secure the catch 316 in open or closed positions. Each hinge mechanism is selected based on desired range of motion, retention force, durability, and aesthetic requirements, and may be combined or substituted as appropriate.

[0075] Freeform movement may be enabled by configuring the catch 316 to rotate, pivot, or slide relative to its respective end portion without the constraint of a fixed axis or track. For example, the catch 316 may be mounted on a ball-and-socket joint, allowing multi-directional movement to align with the post during closure. Freeform movement supports adaptive engagement, enabling the earring 300 to self-index and maintain generally parallel orientation regardless of ear lobe thickness or piercing angle. This approach reduces insertion force, enhances comfort, and minimizes accidental disengagement. The freeform mechanism may be visually concealed within the earring 300 structure to preserve a minimalist aesthetic. As such, the freeform movement may be designed to maintain the stability triangle geometry and robust retention under dynamic loads.

[0076] Similar to the earring 100, the post 322 may be configured to be moved (e.g., pivoted or swiveled toward or away from the catch 316 or opposing end portion) for the catch 316 to catch the post 322 not over the gap. Movability of the post 322 allows for fine adjustment during closure, improving alignment and retention. It accommodates anatomical differences and piercing angles, reduces insertion force, and enhances comfort. The ability to move the post also supports self-indexing closure, minimizing accidental disengagement and improving safety.

[0077] Similar to the earring 100, the first end portion 320 may be configured to be moved (e.g., pivoted or swiveled toward or away from the catch 316 or opposing end portion) towards the second end portion 314 or vice versa to enable the catch 316 to catch the post 322 not over the gap. For example, the first end portion 320 may be configured to be moved towards the second end portion 314 by squeezing the body 302 at the first end portion 320 and the second end portion 314 toward each other, or the second end portion 314 may be configured to be moved towards the first end portion 320 by squeezing the body 302 at the first end portion 320 and the second end portion 314Docket: 15019214-000642 Patent Specification toward each other. Squeezing the first and second end portions 314 and 320 during closure creates controlled elastic deformation, allowing the earring 300 to adapt to different ear shapes and piercing angles. This improves alignment, reduces closure force, and enhances comfort. The elastic deformation also supports secure retention and minimizes the risk of accidental disengagement, while preserving the visual arc of the earring 300.

[0078] Similar to the earring 100, the first end portion 320 may be configured to be stationary to enable the catch 316 to catch the post 322 not over the gap. The stationary first end portion 320 simplifies the closure mechanism, ensuring repeatable alignment and robust retention. It reduces mechanical complexity, improves durability, and supports consistent visual presentation. This configuration is particularly advantageous for manufacturing and quality control.

[0079] Similar to the earring 100, the second end portion 314 may be configured to be moved (e.g., pivoted or swiveled toward or away from the post 322 or opposing end portion) towards the first end portion 320 to enable the catch 316 to catch the post 322 not over the gap. For example, the second end portion 314 may have a pivot or a pair of internal outwardly facing horns and the catch 316 may have a pair of internal apertures receiving the pair of internal outwardly facing horns to enable such pivoting, or vice versa. Pivoting the second end portion 314 allows for dynamic alignment during closure, accommodating anatomical differences and improving comfort. The horn / aperture mechanism distributes mechanical loads, enhancing durability and retention. This configuration also supports manufacturing flexibility and can be tailored for different design aesthetics.

[0080] Similar to the earring 100, the second end portion 314 may be configured to be stationary to enable the catch 316 to catch the post 322 not over the gap. The stationary second end portion 314 provides a fixed reference for closure, ensuring consistent alignment and robust retention. It simplifies the closure mechanism, improves durability, and supports consistent visual presentation. This configuration is advantageous for manufacturing and quality control.

[0081] Similar to the earring 100, the post 322 may have a section hosting a depression (e.g., a notch) or a projection (e.g., a bump) that engages the catch 316 notDocket: 15019214-000642 Patent Specification over the gap. For example, the section or the post 322 with the section may be configured as an L-shape, a J-shape, a hook shape, or another suitable shape. These geometric features provide mechanical interlocking with the catch 316, enhancing retention and reducing the likelihood of accidental disengagement. They facilitate easier alignment during closure, improving comfort and usability. The features distribute mechanical loads, reducing wear and tear, and can be tailored for aesthetic appeal or functional requirements.

[0082] FIG. 17 shows a frontal face-to-face view of an example of a wearer wearing an earring having a catch with an open-shape portion according to this disclosure. FIG. 18 shows a profile view of an example of a wearer wearing an earring having a catch with an open-shape portion according to this disclosure.

[0083] In particular, a wearer 400 wears the earrings 300 on the right ear and the left ear, such that each of the earrings 300 is generally parallel to the head of the wearer or generally parallel to each other. This modality of wearing each of the earrings 300 is enabled to present in a way that minimizes getting caught on hair, clothing, fingers, or headgear of a wearer thereof, while being configured to be configured to be worn generally parallel to a head of a wearer when an observer faces the head of the wearer face-to-face (e.g., eye-to-eye). When worn bilaterally, the body 302 of each earring 300 aligns generally parallel to the wearer’s head due to the triangular stability formed by the post 322, the catch 316, and the line across the gap. This geometric bias limits forward projection and lateral yaw. As a result, the earrings 300 reduce snag initiation on hair, apparel, or headgear and lower shear contact at the earlobe that otherwise arises when a hoop presents away from the head. The generally parallel presentation also equalizes visual symmetry between the right and left ears for consistent frontal viewing and maintains a coherent gemstone arc along the outer side of the body 302, thereby improving comfort, safety, orientation, and aesthetics in ordinary use.

[0084] As shown in FIG. 17, the earring 300 may be worn generally parallel to the head of the wearer 400 or to another earring 300 as, for example, an orientation in which a primary plane, arc, or longitudinal axis of the earring 300 may be disposed at an angle within about 0 degrees to about 10 degrees (e.g., about 0 degrees to about 5 degrees, about 0 degrees to about 2 degrees) relative to a reference plane of the wearer’s 400Docket: 15019214-000642 Patent Specification head, cheek, or jaw when the earring 300 is worn in its intended position. For example, the longitudinal axis of the body 302 may be exemplified as an imaginary line or curve that extends along the central arc of the body 302, following the path equidistant from the inner and outer edges, and connecting the first end portion 320 to the second end portion 314. For example, the earring 300 may be considered to be worn generally parallel when, during ordinary wear, the visible arc, body, or gemstone arrangement is aligned such that its plane or curve is within about 0 degrees to about 10 degrees of the plane tangential to the surface of the wearer’s 400 head adjacent to the ear. For example, generally parallel orientation may be achieved by configuring the post 322 and the catch 316 to engage at an offset location that biases the earring 300 to settle within this angular range. For example, generally parallel orientation may be exemplified by the earring 300 presenting a continuous arc of decorative elements that faces forward when the wearer 400 is frontally viewed face-to-face (e.g., eye-to-eye), and by the earring 300 minimizing protrusion beyond the cheek-plane. Skilled persons understand that generally parallel orientation may be achieved by any combination of the post 322, the catch 316, the body 302, or other component configurations described herein, provided the resulting angle is within the specified or suitable range.

[0085] The earring 100 or the earring 300 may be supplied (e.g., shipped, gifted, donated, sold, leased) to a merchant or by a merchant to a wearer, such as in a store or by shipping. Supplying includes fabrication, quality inspection (alignment tolerance of post-catch; gap dimension within ±10%), finishing (polish, plating if applicable), sterilization of posts, packaging with alignment guards, and distribution to merchants or direct to wearers via shipping. Documentation can include care instructions and fit guidance for piercing angle ranges.

[0086] The earring 100 may be manufactured (e.g., assembled) by forming links 104 from selected materials; machine or cast marquise settings 104; set gemstones 106 using prong / collet / tension techniques; assemble links 104 end-to-end to form the arc; fabricate section 124 (if used) and join to the arc 102; attach the post 112 at the designed lateral angle (e.g., <45°) and attach the catch 116; verify the stability triangle and non-span over the gap; finish and inspect retention force and insertion path.Docket: 15019214-000642 Patent Specification

[0087] The earring 300 may be manufactured (e.g., assembled) by machining the body segments 304 and 306 with slots 310; set the gemstones 312 outward; install the pivot 308 (pin / sleeve / spring); form arcuate the post 322 to lobe curvature; fabricate bar / plate catch 316 with the slot 318 and attach; tune spring detent (if present) for closure preload; validate orientation and retention under dynamic loads; finish and inspect.

[0088] The earring 100 may be worn by aligning the rectilinear post 112 with piercing while keeping the earring 100 generally parallel to head; insert the post 112 through the lobe; bring the catch 116 laterally to engage not over the gap; confirm detent / slot capture; check generally parallel presentation and comfort; for removal, disengage the catch 116 and withdraw the post 112 with minimal rotation.

[0089] The earring 300 may be worn by aligning the arcuate post 322 with piercing; insert through lobe; pivot the segments 304 and 306 to close; engage the slot 318 with the post 322; confirm generally parallel orientation; for removal, pivot open and withdraw the post 322.
