[Industrial applications]

 This invention is directed to an attachment portion of a decorative body, a screw screw holding portion held at a fixed distance from the attachment portion, a metal fitting body having the attachment portion and the holding portion at both ends, and the holding portion. In an earring having a screw screw that is held by a screw and that can be moved back and forth with respect to the attachment portion, and a crimping plate attached to the tip of the screw screw, the earpiece in which the screw screw holding portion has a new structure It is related to the screw screw knob of.

[0002]

[Prior art]

 Conventionally, the crimping plate in the knob for the screw screw of the earring provided with the attachment part of the decorative body and the crimping plate that can move back and forth with respect to this attachment part is supported by the screw of the screw type. A female screw for screwing the screw was held at a predetermined interval with respect to the attachment part of the decorative body by a U-shaped metal fitting or the like, and a knob provided on the other end of the screw screw was turned to sandwich the earlobe. .

[0003]

[Problems to be solved by the device]

 However, since the conventional screw type knob of the screw type earring has a large number of notched grooves formed around a thin material with a plate thickness of 0.25 to 0.4 mm, the product can be attached to the earlobe. I feel a lot of discomfort when I do.

Further, since the knob is formed in a simple plate shape, there is a drawback that it is inconvenient to operate the screw screw.

This invention is intended to eliminate the above-mentioned drawbacks of the prior art, and provides a knob for a screw screw of an earring that has good operability and does not cause any discomfort when attached to an earlobe. Is what you are trying to do.

[0006]

[Means for Solving the Problems]

 That is, the knob for the screw screw of the earring of the present invention includes the attachment part of the ornament, the holding part of the screw screw which is held at a constant distance from the attachment part, and the attachment part and the holding part at both ends. To turn the screw screw in an earring that has a metal fitting body that is provided, a screw screw that is held by the holding part and that can move back and forth with respect to the attaching part, and a crimping plate that is attached to the tip of the screw screw. The knob is characterized in that a metal plate material is drawn and curved into a ring shape, and a large number of grooves are formed along the thickness direction around the curved portion.

[0007]

[Action]

 In the present invention having such a configuration, since the knob has a predetermined thickness, it is possible to provide a knob for a screw screw of an earring having good operability. Moreover, there is no feeling of discomfort or pain when attached to the earlobe.

[0008] Furthermore, it is possible to bring out a sense of volume and a sense of quality without changing the weight, and it is extremely advantageous in terms of cost and weight reduction when it is applied to an earring application using a precious metal.

【Example】

 An embodiment of a screw screw knob of an earring according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an attachment portion of a decorative body 11 such as a pearl, and a holding portion 3 of a screw screw 4 is connected to the attachment portion 1 by a U-shaped metal fitting body 2 at regular intervals. ing. The holding portion 3 includes a female screw 12 to which the screw screw 4 is screwed.

The screw screw 4 movably held in the holding portion 3 has a crimping plate 5 fixed to the front end and a knob 6 fixed to the rear end. When assembling the screw screw 4, the crimping plate 5, and the knob 6, the screw screw 4 to which either the crimping plate 5 or the knob 6 is attached is screwed into the female screw 12 of the holding portion 3, and then from the holding portion 3. Either the crimping plate 5 or the knob 6 opposite to the above may be fixed to the other end of the protruding screw screw 4.

As shown in FIGS. 2 to 4, the knob 6 is formed by drawing a metal plate material to be curved in a ring shape, and is provided around the curved portion 13 with a large number of grooves 14 along its thickness direction. Is formed. In the figure, the width of the curved portion 13 is 0.8 mm. Further, the size, depth, and number of the grooves 14 can be appropriately determined in consideration of slipperiness, feel, and the like. In the figure, 24 grooves 14 are formed around the curved portion 13, and the groove 14 has a width of 0.25 mm and a depth of 0.2 mm.

As a material for the knob 6, a noble metal material made of an alloy such as gold or platinum whose elasticity is reinforced from the viewpoint of easy fitting and durability when operating the screw screw 4 and other aspects can be suitably used.

When using the knob for the screw screw of the earring configured as described above, simply hold the knob 6 and screw the screw screw 4 into the attachment portion 1 side, and the attachment portion 1 and the pressure plate 5 are joined together. It can be easily attached to the earlobe just by pinching the earlobe. To remove it, just hold the knob 6 and unscrew the screw 4 from the holder 3.

[0015]

[Effect of device]

 In the present invention having such a configuration, since the knob has a predetermined thickness, it is possible to provide a knob for a screw screw of an earring having good operability. Moreover, there is no feeling of discomfort or pain when attached to the earlobe.

[0016] Furthermore, it is possible to bring out a feeling of volume and a sense of quality without changing the weight, and it is very advantageous in terms of cost and weight reduction when applied to an earring application using a precious metal.
