Description

MODULAR JEWELRY CONVERTIBLE TO A SPIN-TOP TOY FOR PERSONAL ENTERTAINMENTCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to and the benefit of United States Provisional Patent Application Serial Number 63468276, filed on 23 May 2023, the disclosure of which is incorporated herein by reference in its entirety.FIELD

[0002] The aspects of the disclosed embodiments relate to modular, convertible jewelry that can be arranged and worn as a bracelet, or necklace, and is able to be converted to a high efficiency spin-top toy for entertainment to be spun on any smooth flat or concave surface, or spun on a provided concave surface base.BACKGROUND

[0003] Fidget toys and spinners have been very popular with all ages in the past few years as an entertainment, a novelty and a stress relief device. Many devices have been invented, marketed and successfully sold, combining buttons, spinners, screws and other actionable parts that do not have any other use than the action itself.

[0004] Novel jewelry combining useful functions such as security bracelets with incorporated pepper-spray vials or necklaces incorporating chambers for hidden items or replaceable pictures have also been invented and patented since the last century.

[0005] Many jewelry items such as necklaces and bracelets have also been designed, patented and sold depicting popular toys such as spin-tops, boomerangs and dreidels.

[0006] All previous designs and inventions fulfill part of a function, but have distinct drawbacks as compared to the current invention in the following areas.

[0007] Dedicated fidgeting toys are items that must be intentionally sought, placed in a pocket or handback for safe keeping, until there is interest for them to be used by the user. They require additional planning, care not to be forgotten or lost somewhere when taken out for use.

[0008] Jewelry providing different useful functions are there to be used seldom and not for entertainment purposes, only to perform the required function the jewelry was designed for if the necessity arises, such as to repel an attacker or to safe keep and keep hidden an item of importance; in the case of a necklace with a storage chamber to give an example.

[0009] Jewelry depicting favorite toys, show the interest and love of an individual for the particular toy, but deprive the user of the joy of using that toy whenever they want, since the toy depicted is not functional. Examples include jewelry depicting spin-tops, boomerangs, dice, or playing cards in pendants, bracelets or earrings.

[0010] The aspects of the disclosed embodiments allow the user to wear the elegant, functional accessory inconspicuously as a fashion accessory without constantly worrying about forgetting or losing their fidget / entertainment / stress relief toy, since it is securely assembled in to the pendant or bracelet configurations already on them, and get to use their favorite toy at any time of their choosing while entertaining themselves and possibly friends through the novelty of transformation of a single item to six or seven different additional, functional and entertaining configurations.SUMMARY

[0011] The aspects of the disclosed embodiments are directed to combining the entertainment of a fidget toy or spin-top, the elegance of wearing a designer bracelet or necklace, and the novelty of easily and seamlessly converting the bracelet to a necklace or a spin-top of several configurations in real time.

[0012] In accordance with the aspects of the disclosed embodiments, there is provided a modular spin-top jewelry pendant assembly, comprising a spin-top main body, and a spin-top axel that can be attached to the spin-top body in several ways.

[0013] The spin-top main body has a plurality of identical and angularly equidistant female threaded holes facing radially inward around its perimeter, allowing for the spin-top axel to be securely fastened on the main spin top body, on any one of the plurality of radial holes, forming the pendant.

[0014] The spin-top axel is constructed on one of its extremities with equivalent male threads to the ones found radially inward on the spin top main body periphery. On the opposite extremity of the spin-top axel, a hole, perpendicular to the axis of the spin-top axel can be found, allowing for the spin-top assembly when configured in this way to accommodate a chain to go through, and to be used as a pendant.

[0015] The spin-top main body has a female threaded hole along the center of its axis on the top side of the spin-top, allowing the threaded side of the spin-top axel to be securely fastened along the axis of the spin-top main body, and form a spin-top toy.

[0016] The assembly can be supplied with a base which consists of a cup, with a radially threaded hole extending from the inside surface, to the outside surface of its annular wall. The spin-top main body can be inserted in this cup and secured in place by fastening and tightening the spin-top axel threaded side, on the annular wall of the base from the outside, radially inwards. The spin-top axel threaded portion, which is longer than the thickness of the base annular wall, is threaded in the base’s threaded hole until it presses against the spin-top main body which in turn is pressed against the opposite internal annular wall of the base, securing it in place through friction and geometrical constrains.

[0017] In this configuration the spin-top assembly can also be used as a slightly larger pendant or keyring if a suitable chain, or leather strip, or clip is secured through the hole on one of the extremities of the spin-top axel.

[0018] The spin-top base further includes a concave surface on the bottom of the cup. If the cup is set upside-down on a flat and horizontal surface, the spin-top can be spun on that concave surface, and kept towards the center of the cup as it spins by gravity and stable-stability forces like a marble returning at the bottom of a bowl when moved to one of the sides.

[0019] The spin-top base can also be held by the user upside down in his hand, while they spin and balance the spin-top on the concave surface for entertainment purposes.

[0020] A wrist-bracelet base can also be provided where the assembled base and spin-top pendant configuration can be placed and secured using a threaded knob, in a similar manner that the spin-top main body is secured on the spin-top base. In this configuration the assembly can be used as a decorative bracelet.

[0021] The bracelet configuration is designed in such a manner, such that the spin-top and concave surface base can be removed without removing the bracelet from the wearer’s hand. This allows for the use of the spin-top and base and spin-top toy, independent from the bracelet.

[0022] The concave surface base can also be secured upside down in the bracelet base, while the bracelet base resides on the user’s hand. In this configuration the user can spin the spin-top on the concave surface of the base, which is secured on the bracelet base, which in turn is attached to the user’s wrist so that the user can try to balance the entire bracelet / spinning spin- top, on their wrist.

[0023] In a possible implementation form, a modular jewelry device (5) convertible to a spin- top toy (2) for personal entertainment comprises a spin-top main body (6) having a cylindrical axisymmetric shape, with a top flat surface, with a top hole (14) along an axis of the spin-top main body (6) on a top surface of the spin-top main body (6), and a bottom hole (23) along theaxis of the spin-top main body (6) on a bottom surface of the spin-top main body (6), wherein the top hole (14) is threaded with female threads, and the bottom hole (23) is configured so that a bearing ball (22) made of hard material, and of a diameter slightly larger than a diameter of the bottom hole (23), can be press fitted at a bottom of the spin-top main body (6), such that less than half of a diameter of the bearing ball (22) remains exposed; and wherein the spin top main body (6) also comprises a plurality of angularly equidistant threaded holes (11) around a perimeter of the spin top main body (6), with the plurality of holes (11) facing radially inwards from the perimeter; a spin-top base (8) with a vertical annular wall (18) having an internal vertical annular surface (30) and an external annular vertical surface (29), and a bottom disk (42) where a top surface (43) of the bottom disk (42) is flat, and a lower or external surface (19) of the bottom disk (42) is concave, and a radially outward threaded hole (17), traversing an entire thickness of the vertical annular wall (18), from the inner vertical annular surface (30) to the outer vertical annular surface (29) of the vertical annular wall ( 18); a spin-top axel (7) of a generally cylindrical shape, with an axis hole (13), such that a chain or any other elongated and flexible material formed in a closed loop can be passed through the axis hole (13), such that the spin-top axel (7) can be hung as a pendant, and a threaded portion (12) along the center axis of the spin-top axel (7), the threaded portion (12) configured to be fastened in the top hole (14) of the spin-top main body (6), creating a functional spin-top toy (2) that can be spun through applying torque on a main portion (44) of the spin-top axel (7), a bracelet base (31) with an annular wall (41) having a vertical internal annular surface (32), and an outer surface (33) of any desirable shape, and a disk shaped bottom (46), with a flat internal top disk surface (47), and an external bottom cup surface (48) of any desirable shape, and a radially threaded hole (20) completely traversing the annular wall (41), from the vertical internal annular surface (32) to the external annular surface (33), and a right side up, u-shaped opening (34) starting from a top of the annular wall (41) and finishing at, or just above the top surface (47) of thedisk (46), and two diametrically opposite cutouts (36) on a bottom of the bracelet base (31), having a pair of holes (37), one hole (37) on each side of each cutout (36), such that a traditional watch band can be attached, creating a watch-like bracelet; a knob (10) with a cylindrical portion of any cross-sectional shape, with a male threaded round cylindrical portion (40) at one of its extremities, such that the knob (10) can be fastened in a radial threaded hole (20) on the annular wall (41) of the bracelet base (31), such that the knob (10) can secure a pre-inserted spin-top main body (6), spin-top base (8), and spin-top axel pendant configuration (3), into an internal cup area of the bracelet base (31), where the concave lower or external surface (19) of the cup bottom disk (42) of the spin-top base (8) and the internal flat bottom bracelet surface (47) meet, where the threaded portion (40) of the knob (10) is longer than a thickness of the bracelet base annular wall (41), and the threaded portion (40) of the knob (10) presses on the external annular surface (29) of the annular wall (18) of the spin-top base (8), securing the pendant configuration (3) in place.

[0050] With reference to the drawings in FIGs. 1 through 18 thereof, a new Modular lewelry Convertible to a Spin-top Toy for Personal Entertainment device, embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral (5) are disclosed.

[0051] Referring to FIGS. 1-3, the pendant (1) generally comprises a spin-top main body (6) and a spin-top axel (7), where the spin-top main body (6) is configured with a plurality of identical and equidistant female threaded holes (11) facing radially inward around the perimeter each of which can accommodate the spin-top axel male threads (12) found on one of the extremities, in order to form a pendant.

[0052] Referring to FIG. 3. spin-top axel (7) comprises a cylindrical rod of varying diameter, with male threads (12) found on one of its extremities, and ahole (13) perpendicular to the axis of the axel on the other extremity, that can accommodate a chain, or string of any suitable kind going through it in order to gain the capacity to hang as a pendant, or attached on a key-ring chain to be used as a keyring.

[0053] The spin-top main body (6), comprises a metal, or other suitable material part, of generally cylindrical geometry, referred to as the main body core (24) (see FIG. 15), with a conical or other diminishing diameter shape at the bottom of the cylinder (25), a hole of varying diameter along the center axis (14), and a press-fitted bearing ball (22).

[0054] The hole of varying diameter along the center axis (14) of the main spin-top body (6) at the bottom conical side (25) of the cylindrical part (24), denoted with the numerical (23) in FIG. 15 is dimensioned such that it can accommodate a press-fitted bearing ball (22) of varying materials such as ceramic, metal or crystalline structure that serves as the spinning center for the spin-top toy configuration (2) and as an ornament in the pendant configuration (1).

[0055] The hole of varying diameter along the center axis (14) of the main spin-top body (6) at the top of the cylindrical part of the main body core (24), denoted with the numerical (26), is threaded with female threads of the same type as the male threads (7) on one of the extremities of spin-top axel (7), in order for spin-top axel (7) to be fastened on spin-top main body (6), and form the spin-top toy configuration (2).

[0056] Referring to FIG. 16, the cylindrical geometry of the main body core (24) of spin-top main body (6), further comprises an internal cylindrical core (27) of lighter or lower density material, as an example Aluminium, and an outer ring (28) of a heavier material, as an example brass, so that the overall rotational moment of inertia of the spin-top main body (6) is higher than if constructed using only Aluminium and therefore create a longer lasting spin when spin- top toy (2) is spun at a particular speed, but the overall weigh of the assembly is far lower than if the entire cylindrical body of the main body core (24) was constructed using only Brass, so that it can be worn more comfortably when used as a pendant (1).

[0057] Referring to FIG. 7, spin-top base (8), comprises a metal cup, with an annular wall ( 18), with an inner annular wall diameter slightly higher than the external diameter of spin-top main body (6) and a radially outward hole (17), extending through the annular wall (18) from the inner annular wall surface (29), to the outer annular wall surface (30) with the same type of threads (12) as found on one of the extremities of spin-top axel (7), and having a concave surface (19) as the outer surface at the bottom of the cup geometry’s spin-top base (8).

[0058] Spin-top main body (6) can be placed in the spin-top base (8) cup with its flat surface towards the internal bottom of the cup, and secured thereon with spin-top axel (7) fastened on the spin-top base annular wall ( 18), radially inward from the annular wall external surface (29), through the radially inward spin-top base threaded hole (17), where the threaded portion (12) of the spin-top axel (7), is longer than the thickness of the annular wall (18), the threaded portion (12) of spindle axel (7) penetrates the internal annular surface (30) of annular wall (18)and pushes on the spin-top main body (6), securing it thus through friction and geometry constrains within the spin-top base (8), creating the larger pendant configuration (3).

[0059] Spin-top base (8) can alternatively be separated from the rest of the assembly and placed face down or in an upside-down cup position, with the spin-top base concave surface (19) on top, so that spin-top toy configuration (2) can be spun and placed on concave surface (19) for entertainment purposes, since due to the concave nature of surface (19) the spinning spin-top toy (2) will tend to spin towards the center creating configuration (4).

[0060] Configuration (4) can also be held by the user, as shown in FIG. 14, in order to balance the spindle top in the center of concave surface (19), exhibiting skill for entertainment purposes.

[0061] The bracelet in configuration (4) is also provided with a wrist-bracelet base assembly (9), comprising a bracelet cup (31), and a threaded knob (10), as shown in FIG. 10, for example.

[0062] The bracelet assembly cup (31) has a slightly larger internal annular wall diameter than the external diameter of spin-top base (8), and consists of an annular wall with a generally vertical internal annular surface (32), an arbitrary shape outer annular surface (33), and a radially oriented threaded hole (20), going all the way through the wrist-bracelet base cup annular wall (41) from the internal surface (32) to the external annular surface (33), and a U- shaped cutout (34) with a slightly larger diameter than spin-top axel (7), and the bottom surface of bracelet assembly cup (31), features two cutouts (36), with a set of transverse holes (37) each, such as to form a receptacle set for the attachment of a traditional watch-strap or chain (38).
