[0055]
The use of the seventh connector 250 is substantially the same as in the previous embodiments. However, in this embodiment, even when a flat male fitting 252 is inserted, the presence of the support portion 276 allows the inside of the female fitting 260 to be used. Thus, the male metal fitting 252 does not wobble at the time of connection. Such a fifth connector 250 can be used for an accessory such as a chain necklace.
[0056]
FIG. 22 is a perspective view showing the eighth connector 280 showing the eighth embodiment of the present invention and the state of use thereof.
The eighth connector 280 includes a coil spring that urges the lid 282 that opens the entire bottom surface of the heart box shape and the bottom body 290 that opens the entire top surface of the heart box shape in the closing direction. (Not shown), a female bracket 281 that is pivotally supported by a telescopic support pin 70 in the width direction and is formed to be openable and closable, for example, has a total length used for the third connector 100. The short male metal fitting 101 is attached and detached.
[0057]
The lid 282 of the female metal fitting 281 in this embodiment has a substantially semicircular shape that engages with the engagement groove 105 of the male metal fitting 101 from one side in the width direction, that is, in parallel with the axial support direction by the support pin 70. The first locking recess 287 is formed, and similarly, a second locking recess 292 is formed in the bottom body 290.
In addition, gentle slopes 283 and 293 are formed in the downward direction of the lid body 282 and the bottom body 290, respectively, so that the operation of pressing both to open the male fitting can be performed smoothly. Furthermore, the female fitting 281 is provided with a connection ring portion 289 for connecting one end of a necklace or the like.
[0058]
In the eighth connector 280, the male metal fitting 101 is connected to the female metal fitting 281 from the width direction.
Therefore, it is very convenient because the connecting tool 280 can be positioned on the front surface and can be attached / detached visually while wearing a jewelry such as a necklace.
In addition, for example, by making the female fitting 281 decorative such as a heart shape, if the connector 280 is positioned on the front surface when the necklace is used, it can also serve as a pendant.
[0059]
As described above, the present invention has been described with reference to several illustrated embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. Needless to say, a wide variety of changes can be made.
