For example, in Patent Document 1, a spring fixed to one member presses the other member to generate a force to close the gap. However, in the configuration as disclosed in Patent Document 1, the vicinity of the movable end portion of the spring may be shaken at the time of mounting. When such shaking occurs, the shaft that rotatably connects the one member and the other member is likely to rattle, making it impossible to open and close smoothly. Also, if the movable end of the spring becomes too loose, the spring may become unable to press against the other member, in which case the jewelry may become detached from an object such as an ear.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an accessory capable of suppressing vibration of the movable end of a spring.

The second fixing portion 54 is located near the first fixing portion 53 and between the first fixing portion 53 and the first mounting portion 21 . Both the first fixing portion 53 and the second fixing portion 54 are arranged so as to connect the two opposing walls 52 in the rotation axis direction. As shown in FIG. 4 , the first fixing portion 53 is located closer to the inner space 17 than the outer peripheral portion 51 is. A gap is provided between the first fixing portion 53 and the outer peripheral portion 51 . The second fixing portion 54 forms a wall that connects the two opposing walls 52 and extends from the outer peripheral portion 51 toward the inner space 17 . In the example of FIG. 4 , the end surface of the second fixing portion 54 facing the inner space 17 is flush with the two end surfaces of the two opposing walls 52 facing the inner space 17 .

The receiving portion 55 is positioned between the first fixed portion 53 and the first rotating portion 22 . The receiving portions 55 are recesses provided in the two opposing walls 52 and are recessed outward from the inner space 17 .

As shown in FIG. 4 , the spring 13 is positioned inside the inner space 17 with respect to the outer peripheral portion 51 . The spring 13 is a linear member with a circular cross section. The material forming the spring 13 is, for example, a titanium alloy. The spring 13 has a fixed end 61 and a movable end 62 . The spring 13 comprises a first spring region 63 with a fixed end 61 and a second spring region 64 with a movable end 62 . The spring 13 is bent approximately 90 degrees in a curve at a bend 65 between the first spring region 63 and the second spring region 64 .

The first spring region 63 protrudes toward the inside of the inner space 17 away from the outer peripheral portion 51 of the first member 11 . The first spring region 63 is sandwiched and fixed (or limited in movement) between the first fixed part 53 and the second fixed part 54 . That is, the fixed end 61 of the spring 13 is fixed (or limited in movement) relative to the first member 11 . The second fixed portion 54 limits movement of the first spring region 63 away from the facing portion 24 . The first fixed portion 53 limits the movement of the first spring region 63 in the direction towards the facing portion 24 .

A region of the second spring region 64 that is close to the bent portion 65 is located between the outer peripheral portion 51 that is a part of the first member 11 and the first fixing portion 53 . Movement of the second spring region 64 in a direction along the first spring region 63 is thus restricted. That is, the region of the spring 13 near the bend 65 is fixed (or has limited movement) relative to the first member 11 .

As shown in FIG. 1 , the intermediate fixing member 15 is configured to be insertable into the receiving portion 55 . The intermediate fixing member 15 is fitted in the receiving portion 55 . The intermediate fixing member 15 is arranged so as to connect between the two facing portions 24 .

The pinching of the spring 13 limits the movement of the spring 13 . Therefore, in operation, the portion of the second spring region 64 between the intermediate fixed member 15 and the movable end 62 moves relatively large.

As shown in FIG. 4, the spring 13 applies a pressing force to the first contact portion 41 at the closed rotation position to prevent the rotation of the second member 12 in the direction in which the gap 16 becomes larger. That is, the spring 13 presses the first contact portion 41 in a direction to reduce the gap 16 at the closed rotation position. In addition, the spring 13 applies a pressing force to the contact portion 40 to suppress the rotation of the second member 12 in the direction in which the gap 16 becomes larger in the first rotation range. The first range of rotation is a portion of the total range of rotation between the closed rotational position and the open rotational position and includes the closed rotational position.

The spring 13 contacts the contact portion 40 at a location sandwiched between the two opposing portions 24 in at least a partial rotation range of the first rotation range and including the closed rotation position. As shown in FIG. 4, the two opposing portions 24 extend inwardly beyond the spring 13 toward the inner space 17 in a range of rotation, including the closed rotational position. In the first rotation range, the spring 13 is configured to press the contact portion 40 in a state in which the movable end portion 62 is separated from the second member 12 in the direction orthogonal to the rotation axis of the connecting portion 14. . In another example, movable end 62 may contact second member 12 during at least a portion of the first range of rotation.

As shown in FIG. 5, the spring 13 applies a pressing force to the second contact portion 42 to suppress the rotation of the second member 12 in the direction in which the gap 16 becomes smaller in the second rotation range including the open rotation position. applied to That is, the positional relationship between the first member 11 and the second member 12 is relatively stable in the second rotation range.

At a certain rotational position between the closed rotational position and the open rotational position, the distance between the virtual rotational axis of the connecting portion 14 and the spring 13 is maximized, so that the first rotational range and the second rotational range In order to change the state of the accessory 1 between them, it is necessary for the user to apply a certain amount of force against the pressing force of the spring 13 .

The spring 13 contacts the third contact portion 43 while the accessory 1 is transitioning between the first rotation range and the second rotation range. That is, when the accessory 1 transitions from the first rotation range to the second rotation range, the spring 13 contacts the first contact portion 41, the third contact portion 43, and the second contact portion 42 in order. When transitioning from the second rotation range to the first rotation range, the spring 13 contacts the second contact portion 42, the third contact portion 43 and the first contact portion 41 in order. As shown in FIG. 4, in the first rotation range in this example, the spring 13 has a ridge-like shape between the first contact portion 41 and the third contact portion 43 of the first contact portion 41 .

As a result, the contact position between the spring 13 and the contact portion 40 is restricted to the range sandwiched between the two opposing portions 24, so that the deviation of the contact position between the spring 13 and the contact portion 40 is easily suppressed.
In addition, in at least a partial rotation range including the closed rotation position of the first rotation range, the portion of the spring 13 near the contact portion 40 is sandwiched between the two opposing portions 24, so that the closed rotation position The deflection of the spring 13 in the vicinity is reduced, and the opening and closing operations of the first member 11 and the second member 21 can be performed smoothly. As a result, an object (such as an earlobe) can be pinched or removed in the vicinity of the closed rotation position.
In addition, since the two opposing portions 24 have a function of rotatably sandwiching and supporting the protruding portion 34 and a function of supporting the rotating shaft of the connecting portion 14, an independent member only for suppressing vibration of the spring is provided. The structure can be simplified as compared with the case where it is provided.

According to this embodiment, since the contact position between the spring 13 and the contact portion 40 is limited to the range between the two facing portions 24 of the first rotating portion 22, the contact portion between the spring 13 and the contact portion 40 is Fluctuation of the contact position is easily suppressed.

According to this embodiment, the movement of the spring 13 in the direction toward the facing portion 24 and in the direction along the second spring region 64 is restricted in the vicinity of the first spring region 63 by the first fixing portion 53. Therefore, it is possible to prevent the spring 13 from coming off with a simple configuration.

According to this embodiment, the second fixing portion 54 restricts the movement of the spring 13 in the direction away from the facing portion 24 in the vicinity of the first spring region 63, so that the spring 13 can be removed with a simple configuration. can be prevented.

According to this embodiment, since the spring 13 is sandwiched between the intermediate fixing member 15 and a part of the first member 11, compared to the case where only the fixed end portion 61 is used for fixing, the spring 13 near the movable end portion 62 is The elastic force of the spring 13 can be increased.
Further, since the intermediate fixing member 15 is inserted into the receiving portion 55 of the first member 11, the intermediate fixing member 15 is inserted into the receiving portion 55 after the spring 13 is attached to the first member 11. Then, the intermediate fixing member 15 can be fixed to the first member 11 by a method such as welding. Therefore, the operation of attaching the spring 13 to the first member 11 can be easily performed.

According to this embodiment, since the spring 13 is a linear member having a circular cross section, it is less likely to run over the facing portion 24 compared to a flat spring.
Moreover, since the spring 13 is a linear member having a circular cross section, it is easier to obtain a large elastic force with less material than when the spring is a flat plate.

According to this embodiment, since the spring 13 presses the contact portion 40 at a position closer to the fixed end portion 61 than the movable end portion 62 , the contact portion 40 is pressed with a greater force than when the movable end portion 62 is in contact with the contact portion 40 . can be pressed.
