Description

[Technical Field]

[0001] The present invention relates to a ring having a ring body and a lid. [Background technology]

[0002] So-called rocket rings, which have a lid that can be opened and closed relative to a ring body, have been known for some time (see, for example, Patent Document 1). In rocket rings, the ring body and the lid are connected via a hinge, and the lid can be opened and closed by rotating around the hinge axis. It is also known that rocket rings were used for the most recent championship rings in Major League Baseball in the United States. [Prior art documents] [Patent documents]

[0009] A ring 1 according to one embodiment of the present invention will now be described with reference to the accompanying drawings. Note that the following description is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0010] [Overall configuration] A ring 1 according to this embodiment is shown in the perspective view of Fig. 1, the front view of Fig. 2(a), the side view of Fig. 2(b), and the plan view of Fig. 3. The illustrated ring 1 is a championship ring made to commemorate a victory in a sport such as baseball.

[0011] 1 to 3, the ring 1 includes a ring body 10 that is worn on a finger, and a lid 30 that is attached to the ring body 10 so as to cover a portion of the ring body 10. The materials for the ring body 10 and the lid 30 are not particularly limited, but metals such as gold alloys or silver alloys are used, for example.

[0012] As shown in the exploded side view of Figure 4, in the ring 1 of this embodiment, unlike a rocket ring, the lid portion 30 is provided separately from the ring body portion 10. Therefore, the ring 1 is provided with a detachable portion 50 for attaching and detaching the lid portion 30 to and from the ring body portion 10. The configuration of the detachable portion 50 will be described later.

[0013] [Ring body] As shown in the plan view of FIG. 5(a) and the side view of FIG. 5(b), the ring body 10 includes, for example, a disk-shaped base portion 12 and a ring portion 14 protruding from the rear surface of the base portion 12.

[0014] The ring portion 14 has a semi-elliptical outline in a side view and a generally inverted triangular outline in a front view (see FIG. 2(a)). That is, the ring portion 14 has a shape that gradually flattens toward the tip (as it gets farther away from the base portion 12). The ring portion 14 has an insertion hole 16 that penetrates laterally, through which the wearer's finger is inserted. The outer peripheral surface of the ring portion 14 is decorated by setting gemstones such as diamonds, engraving, coloring, etc. The inner peripheral surface of the ring portion 14 may also be decorated by engraving, etc.

[0015] A plurality of protrusions 18 may be provided on the outer peripheral surface of the base portion 12. The protrusions 18 may have, for example, a rectangular outline along the circumferential direction. The surface of the protrusions 18 may be decorated with, for example, stone setting. The protrusions 18 may be provided in a shape and arrangement that imitates the balconies of an actual stadium.

[0016] The surface of the base portion 12 is the portion that is covered by the lid portion 30. A flat main body side mating surface 20 is provided on the peripheral edge of the surface of the base portion 12. The main body side mating surface 20 is provided in an annular shape.

[0017] A groove-shaped notch 22 extending in the circumferential direction is provided on the inner periphery of the main body side mating surface 20. The notch 22 is provided to constitute an engagement / disengagement mechanism 60, which will be described later. A plurality of (for example, two) notches 22 are arranged at intervals in the circumferential direction. The two notches 22 are arranged so as to face each other across the center of the base portion 12. The end faces on both sides in the longitudinal direction of each notch 22 function as stoppers that restrict the movement range of a hook 68, which will be described later, within the notch 22.

[0018] Furthermore, a plurality of (for example, four) main body side magnets 72 that constitute an attraction section 70, which will be described later, are provided on the main body side mating surface 20. The configurations of the attraction section 70 and the main body side magnets 72 will be described later.

[0019] The portion of the surface of the base 12 that is inward of the main body mating surface 20 forms a decorative portion 24 that is exposed when the lid 30 is removed. In the example shown, the decorative portion 24 includes a field portion 26 that imitates the field of an actual stadium, and a spectator seat portion 28 that imitates the spectator seats of the stadium. The field portion 26 may be decorated with, for example, emerald stones, and the spectator seat portion 28 may be decorated with, for example, diamond stones.

[0020] [Lid] As shown in the side view of FIG. 6( a ) and the bottom view of FIG. 6( b ), the lid portion 30 includes, for example, a circular frame portion 32 and a cover portion 34 surrounded by the frame portion 32 .

[0021] The back surface of the frame portion 32 forms a flat, annular lid-side mating surface 40. When the lid portion 30 is attached to the ring main body portion 10, the lid-side mating surface 40 is placed on the main body-side mating surface 20. The lid-side mating surface 40 is provided with a plurality of (e.g., two) hooks 68 that constitute the engaging / disengaging mechanism 60 described below, and a plurality of (e.g., four) lid-side magnets 74 that constitute the adsorption portion 70 described below. The configurations of the hooks 68 and the lid-side magnets 74 will be described later.

[0022] In the illustrated example, the cover portion 34 is provided so as to bulge in a dome shape from the frame portion 32 toward the opposite side from the lid-side mating surface 40. The cover portion 34 may have a shape that imitates, for example, a retractable dome roof of an actual dome stadium.

[0023] [Detachable part] The detachable portion 50 for attaching and detaching the lid portion 30 to and from the ring main body 10 will be specifically described below.

[0024] The detachable part 50 is provided with an engaging / disengaging mechanism 60 that can be switched between an engaged state (see FIGS. 3 and 8) and a disengaged state (see FIG. 9) by rotation of the lid part 30 in a state in which the lid-side mating surface 40 is superimposed on the main body-side mating surface 20. In the engaged state by the engaging / disengaging mechanism 60, separation of the lid-side mating surface 40 from the main body-side mating surface 20 is restricted, and in the disengaged state, such separation is permitted.

[0025] The detachable part 50 also includes an attraction part 70 that, in the engaged state, attracts the cover-side mating surface 40 to the main body-side mating surface 20 by magnetic force. The configurations of the engaging / detaching mechanism 60 and the attraction part 70 will be described below in order.

[0026] [Engagement / disengagement mechanism] As shown in particular in Figure 5(a), the engagement / disengagement mechanism 60 comprises a regulating portion 62 provided to extend circumferentially on the main body side mating surface 20, and an opening portion 64 provided at one end of the regulating portion 62 on the main body side mating surface 20.

[0027] Specifically, two pairs of restricting portions 62 and opening portions 64 are arranged on the main body side mating surface 20 at intervals (for example, at angular intervals of 180°) in the circumferential direction.

[0028] Each of the openings 64 is provided at one longitudinal end of the above-mentioned notch 22. The openings 64 are configured as spaces that are open to the surface side of the main body mating surface 20, to the radially inner side, and to one circumferential side (the restricting portion 62 side).

[0029] The restricting portion 62 is provided in the remaining portion of the cutout 22 excluding the open portion 64. Specifically, the restricting portion 62 is formed by protruding radially inward from the inner peripheral surface of the cutout 22 like an eave. The restricting portion 62 is made of the same material as the ring main body 10 and is provided integrally with the ring main body 10. The radially inner end of the restricting portion 62 is located radially outward from the inner periphery of the main body side mating surface 20. The space behind the restricting portion 62 is connected to the open portion 64.

[0030] As shown in the side view of Fig. 6(a), the bottom view of Fig. 6(b), and the cross-sectional view of Fig. 7 (cross-sectional view taken along line AA in Fig. 3), the engaging / disengaging mechanism 60 further includes a hook 68 provided to protrude from the lid-side mating surface 40. The hook 68 is made of the same material as the lid portion 30 and is provided integrally with the lid portion 30, for example.

[0031] Specifically, two hooks 68 are arranged circumferentially at an interval (for example, an angular interval of 180°) on the lid-side mating surface 40. Each hook 68 is provided along the inner periphery of the lid-side mating surface 40. The hooks 68 are provided so as to bend radially outward in an L-shape.

[0032] In the engaged state shown in the cross-sectional view of Fig. 7 and the plan views of Fig. 8(a) and Fig. 8(b), the hook 68 is provided to engage with the above-mentioned restricting portion 62. Specifically, the hook 68 is engaged so as to be caught on the back side of the eave-shaped restricting portion 62. By engaging the hook 68 with the restricting portion 62 in this way, movement of the lid portion 30 in a direction away from the ring main body 10 is restricted.

[0033] On the other hand, in the disengaged state shown in the plan views of FIGS. 9( a ) and 9 ( b ), the hook 68 is disengaged from the restricting portion 62 and can be moved in and out of the open portion 64 .

[0034] When the lid portion 30 is attached to the ring main body 10, the hooks 68 of the lid-side mating surface 40 are inserted into the openings 64 of the main body-side mating surface 20, thereby allowing the lid-side mating surface 40 to be superimposed on the main body-side mating surface 20. With the lid-side mating surface 40 superimposed on the main body-side mating surface 20 in this manner, the lid portion 30 is rotated to one side in the circumferential direction (toward the restricting portion 62) (for example, counterclockwise in a plan view), whereby the hooks 68 engage with the restricting portion 62.

[0035] When the lid portion 30 is removed from the ring main body 10, the lid portion 30 is rotated to the other circumferential side (toward the open portion 64), causing the hook 68 to disengage from the restricting portion 62 and become removable from the open portion 64.

[0036] As described above, the engagement / disengagement mechanism 60 in this embodiment employs a twist lock mechanism in which the ring body 10 and the lid 30 are engaged with and disengaged from each other by twisting the lid 30 .

[0037] [Adsorption part] As shown in FIGS. 8 and 9, the adsorption section 70 includes a body-side magnet 72 provided on the body-side mating surface 20 and a lid-side magnet 74 provided on the lid-side mating surface 40.

[0038] For example, neodymium magnets are used for the body-side magnet 72 and the lid-side magnet 74. This allows for a stronger magnetic force than natural magnets, and the magnetic force is maintained well over a long period of time. In this case, when manufacturing the ring 1, first, the material for the body-side magnet 72 is assembled to the body-side mating surface 20, and then the material for the lid-side magnet 74 is assembled to the lid-side mating surface 40, and then magnetization is performed by passing electricity through them. This improves the workability during assembly compared to when pre-magnetized magnets are assembled to the mating surfaces.

[0039] Specifically, a plurality of (for example, four) body-side magnets 72 are arranged at intervals in the circumferential direction on the body-side mating surface 20. The four body-side magnets 72 are arranged adjacent to both ends of each notch 22 so as to avoid each of the restriction portions 62.

[0040] Similarly, a plurality of (for example, four) lid-side magnets 74 are arranged at intervals in the circumferential direction on the lid-side mating surface 40. These lid-side magnets 74 are arranged to correspond to the above-mentioned body-side magnets 72. In other words, each lid-side magnet 74 is arranged so that it is aligned with the corresponding body-side magnet 72 only when in an engaged state.

[0041] 8, the circumferential position of each lid-side magnet 74 coincides with the circumferential position of the corresponding body-side magnet 72, causing a strong magnetic force to act between the body-side magnet 72 and the lid-side magnet 74. This causes the body-side mating surface 20 and the lid-side mating surface 40 to be firmly attracted to each other, thereby suppressing unintentional rotation (twisting) of the lid part 30 relative to the ring body part 10. Therefore, the engaged state of the engagement / disengagement mechanism 60 is reliably maintained, reliably preventing the lid part 30 from falling off the ring body part 10.

[0042] 9, the body-side magnet 72 and the lid-side magnet 74 are spaced apart from each other in the circumferential direction, and the magnetic force acting between the body-side magnet 72 and the lid-side magnet 74 is extremely weak. This allows the lid 30 to be easily removed from the ring body 10.

[0043] With the ring 1 configured as described above, the combination of the engagement / detachment mechanism 60, which functions by rotation (twisting) of the lid portion 30, and the attraction portion 70, which functions by magnetic force, enables the lid portion 30 to be attached to and detached from the ring body 10. This provides a completely new type of ring 1 in which the lid portion 30 is completely separated from the ring body 10 when removed, and also reliably prevents the lid portion 30 from falling off when attached. Furthermore, unlike rocket rings, the engagement / detachment mechanism 60 and attraction portion 70 of the ring 1 of this embodiment do not require hinges, which have poor durability, making it possible to improve the durability of the ring 1.

[0044] Although the present invention has been described above with reference to the above-mentioned embodiments, the present invention is not limited to the above-mentioned embodiments.

[0045] For example, in the above embodiment, the ring 1 was described as a championship ring for ball games, etc., that resembles the roof and grounds of a dome stadium, but the present invention is not limited to championship rings and can be applied to any type of ring.

[0046] In addition, in the above-described embodiment, the restricting portion 62 and the opening portion 64 are provided on the main body mating surface 20, and the hook 68 is provided on the lid mating surface 40, but the restricting portion and the opening portion may be provided on the lid mating surface, and the hook may be provided on the main body mating surface. Furthermore, the specific configuration of the engaging / disengaging mechanism including the restricting portion, the opening portion, and the hook may be changed as appropriate as long as the functions of each are not impaired.

[0047] Furthermore, in the above-described embodiment, two notches 22, two restricting portions 62, and two opening portions 64 are provided, and four main body side magnets 72 and four lid side magnets 74 are provided, but in the present invention, the number and arrangement of these elements can be changed as appropriate as long as their respective functions are not impaired.
