Hereinafter, the accessory according to the present invention will be described in detail based on embodiments with reference to the drawings. Note that the drawings schematically show members constituting the accessory, and the dimensions and dimension ratios of these actual objects do not necessarily match the dimensions and dimension ratios on the drawings. In addition, unless otherwise specified, in this specification, for the sake of convenience, directions such as “front”, “back”, “left”, “right”, “up” and “down” are based on the orientation of the accessory shown in FIG. Represents. In addition, duplication description is abbreviate | omitted suitably and the same code | symbol may be provided to the same member.

1 to 5 show a pendant top 1 according to the first embodiment of the present invention. The pendant top 1 includes a decorative member 2 having a jewel 3 such as diamond and a pedestal 4 that holds the jewel 3, and a frame 5 that supports the decorative member 2 in a swingable manner.

The pedestal 4 of the decorative member 2 is made of a ring-shaped member that holds the outer periphery of the jewel 3. The base 4 has a pair of arm portions 6 on both the left and right sides. The pair of arm portions 6 have the same shape on the left and right, and project outward from the left and right sides of the base 4 obliquely upward. The upward angle of each arm 6 is such that the inclination angle θ from the arm base end 6a on both sides of the base 4 is about 5 to 20 °, preferably 10 to 15 °. The inclination angle θ is appropriately changed depending on the type, size, weight, shape, etc. of the accessory, and is also appropriately changed depending on how the decorative member 2 is swung.

Thus, the decorative member 2 has a pair of arm portions 6 projecting from the base 4 with a predetermined inclination angle θ, and the arm portions 6 are placed on the receiving portions 7 of the frame 5 and supported by point contact. Smooth rocking can be obtained. The inclination angle θ is an angle from a horizontal line with the center of gravity O of the decorative member 2 as the center. Therefore, as shown in FIG. 4, the support point P where the arm portion 6 and the receiving portion 7 are in point contact is located at least the dimension h above the center of gravity O of the decorative member 2. Thus, since the support point P is located above the center of gravity O of the decorative member 2, the decorative member 2 can be smoothly swung. The value of the dimension h is not particularly limited. The arm portion 6 is formed by a cylindrical member having the same diameter. Therefore, it has a circular arc surface 6b at the lower end. The arm 6 is fixed to the outer peripheral surfaces of both sides of the pedestal 4 by brazing, or by means such as press-fitting into recesses (not shown) provided on the pedestal 4. Furthermore, when the base 4 is cast, it can be formed integrally.

The frame 5 is formed of a semicircular member that covers almost the upper half of the decorative member 2. The inside is hollow. The frame 5 is disposed along the outer periphery of the decorative member 2, but is disposed with a certain gap c 1 between the outer peripheral surface of the base 4 so that the decorative member 2 does not contact the frame 5 when swinging. ing. The frame 5 has a pair of receiving portions 7 on both sides. The receiving portion 7 is for supporting the arm portion 6 placed thereon, and is formed of a rectangular parallelepiped member having an edge 7a at the upper end as shown in FIGS. The receiving part 7 is arrange | positioned in the state which made the rectangular parallelepiped member stand upright in the front-back direction of the accessory member 2 orthogonal to the front of the decoration member 2. The edge 7a is formed at the upper end over the entire length of the rectangular parallelepiped member. That is, the edge 7a is formed in a straight line. Moreover, the edge 7a in this embodiment is formed in an upper end by sharpening the upper part of a rectangular parallelepiped member from the both sides toward the center at the same angle, and making it taper shape. That is, the tip angle of the edge 7a is the same on the left and right. However, the tip angle of the edge 7a can be left-right asymmetric, and the angle can be provided only on one of the left and right sides.

The receiving portion 7 is disposed in a storage portion 5b provided at both end portions of the frame 5, and is fixed to the frame 5 with, for example, screws (not shown) or a hook (see FIG. (Not shown). The height position of the receiving part 7 can be adjusted with respect to the frame 5.

The frame 5 has an opening near the upper end of the receiving portion 7. This opening is formed by a circular hole 5 a having the same cross-sectional shape as the arm portion 6. The circular hole 5a has an inner diameter dimension slightly larger than the diameter dimension of the arm portion 6, and the arm portion 6 is inserted into the inner diameter. Therefore, the circular hole 5 a is opened obliquely upward at the same inclination angle θ as that of the arm portion 6. As shown in FIGS. 2, 4, and 5, the circular hole 5 a has an appropriate gap c 2 between the arm portion 6. The gap c2 ensures free rotation of the arm portion 6 so as not to prevent smooth swinging of the decorative member 2. On the other hand, the gap c2 acts as a stopper that restricts the arm portion 6 from being greatly displaced in the front-rear direction on the edge 7a of the receiving portion 7 when the decorative member 2 swings. Therefore, it is not preferable that the gap c2 is too large.

The frame 5 has a circular ring 5c for passing the chain 8 at the upper end. The pendant top 1 is suspended by a chain 8 passed through the circular ring 5c.

Next, the support structure of the decorative member 2 and the frame 5 in the pendant top 1 having the above configuration will be described. In the decorative member 2, a jewel 3 is held on a pedestal 4. At this time, the arm 6 is not fixed to the base 4. On the other hand, the receiving part 7 is hold | maintained at the accommodating part 5b. As shown in FIG. 4, after arranging the decorative member 2 on the inner side of the frame 5, the arm portion 6 is inserted into the circular hole 5 a of the frame 5 from the outer side, and the tip thereof is fixed to the outer peripheral surface of the pedestal 4. . The fixing means is as described above.

In this way, the pair of arm portions 6 are projected outwardly from both sides of the base 4 obliquely upward. The arm portion 6 intersects with the receiving portions 7 provided on both sides of the frame 5 and is placed on the upper end of the receiving portion 7 in a crossed state. Specifically, the decorative member 2 is supported by making point contact of the arc surface 6 b at the lower end of the arm portion 6 with the edge 7 a at the upper end of the receiving portion 7. Further, the arc surface 6 b at the lower end of the arm portion 6 intersects the edge 7 a at the upper end of the receiving portion 7 while being inclined upward, and makes point contact with the edge 7 a of the receiving portion 7.

Thus, the decorative member 2 is supported by the left and right receiving portions 7 with the pair of arm portions 6 protruding from the left and right sides of the pedestal 4 tilting upward. Therefore, the decorative member 2 is always supported at the center position of the frame 5, and the contact with the inner peripheral surface of the frame 5 and the swinging motion in the left-right direction due to the shifting motion in the left-right direction are effectively suppressed. As a result, the decorative member 2 can easily obtain a smooth swing in the front-rear direction. Further, since the decorative member 2 has the pair of arm portions 6 intersecting the left and right receiving portions 7, the arc surface 6b at the lower end of the arm portion 6 is supported by the upper end of the receiving portion 7 by point contact with the edge 7a. Thus, the swinging of the decorative member 2 in the front-rear direction becomes smoother.

The decorative member 2 can adjust the magnitude and speed of the swinging motion by changing the position where the arm portion 6 and the receiving portion 7 are in point contact with the center of gravity O of the decorative member 2 up and down. The support position P that makes point contact is changed by, for example, changing the inclination angle θ of the arm portion 6 and changing the position of the arm base end portion 6a of the arm portion 6 up and down to further change the edge 7a of the receiving portion 7. It is possible to easily cope with this by changing the height position of the top and bottom.

In the first modification, the shapes of the arm portion 16 and the receiving portion 17 are opposite to those in the above embodiment. That is, the arm portion 16 protruding from the base 4 of the decorative member 2 is formed by a rectangular parallelepiped member, and has an edge 16a at the lower end. The lower edge 16a is inclined upward. The arm portion 16 may be entirely inclined upward, or only the lower edge 16a may be inclined upward. On the other hand, the receiving part 17 is formed of a cylindrical member having the same diameter, and has an arc surface 17a at the upper end.

The opening provided in the frame 5 is a deformed square hole 18 corresponding to the shape of the arm portion 16. The deformed square hole 18 has a certain gap c 3 between its inner peripheral surface and the outer peripheral surface of the arm portion 16. The gap c3 serves as a stopper that prevents the swinging of the decorative member 2 from being disturbed and restricts the arm portion 16 from being greatly displaced from the upper end of the receiving portion 17 in the same manner as in the above embodiment. I am doing.
