Description

[Detailed description of the invention] This invention provides an inserter with a locking protrusion provided at the inner bottom of the dovetail hole in the main body of the clasp, and one end of which is fixed to the protrusion at the inner bottom of the inserter-shaped opening. Relating to a clasp in a netskures formed in such a way that a through hole drilled in the attached bullet plate is fitted and locked, and the clasp main body and the inserter are connected and separated by operating a pressing plate adhered to the back side of the bullet plate. .

A conventional clasp has a bullet plate inside the main body, and a locking portion is provided by bending the free end of the bullet plate at a substantially right angle.
Since the connector was connected to the main body of the clasp by locking the bent portion of the bullet plate provided in the connector to the locking portion, the connection was unstable and there was a drawback that play occurred. Furthermore, when separating the connector from the clasp body, the operator that protrudes to the outside is operated and separated, and the operator gets caught on another object, causing the clasp body and connector to be separated against the user's will. There was a risk that the netcress would be lost due to separation. Furthermore, the controls had the drawback of diminishing the beauty of the decoration.

The present invention is a clasp in a net clasp proposed to eliminate the above-mentioned drawbacks. That is, the present invention provides a locking protrusion inwardly on the inner bottom surface of the dovetail hole 1b of the clasp main body provided with the square hole 1a,
The locking protrusion is connected to the tip of the insertion plate attached to the inner bottom of the square-shaped opening of the inserter, and the through hole of the bullet plate is connected to the tip and a pressing plate is attached to the back of the base. When the inserter is formed to be connected to the clasp main body and the inserter is separated from the clasp main body,
Press a pressure plate provided on the inserter and located inside the square-shaped opening of the inserter, and by the pressure of this pressure plate, the free end of the bullet plate is lifted and the through hole of the bullet plate is opened. The inserter is separated from the clasp body by removing the locking protrusion and pulling the inserter out from the clasp body, and the connection and separation of the clasp body and the inserter are completely eliminated. This is done inside the main body of the clasp, and the base of the inserter, the bullet plate, and the pressure plate are housed in the rectangular opening of the separated inserter, and the bullet plate and pressure plate are inserted into the seams and stitches of the garment so that they do not protrude outward. This is an invention of the clasp for netskures, which is characterized by being formed so that the pressing plate does not get caught and adds to the decorative beauty. This can be explained with reference to the drawings as follows.

In the accompanying drawings, reference numeral 1 has a joint portion opened, formed into a flat rectangular box shape, and provided with a square-shaped hole 1a into which an insertion plate 4 is inserted, and a dovetail-shaped hole 1b into which a bullet plate 5 is inserted below the square-shaped hole 1a. A circular locking protrusion 2 is provided on the upper surface of the bottom wall of the clasp main body 1.
and 2 are planted, and the inserter 3 connected to the opening of the clasp body 1 is formed to have the same width and thickness as the clasp body 1, and to have the same overall shape as the clasp body.

The base of the insertion plate 4 is attached to the inner surface of the upper wall of the inserter 3 having the square-shaped opening 3a, and the length of the free exposed portion of the insertion plate 4 is set to such a length that it contacts the inner surface of the side wall of the clasp main body 1. to form.

The tip of the bullet plate 5 is bonded to the tip of the free exposed portion of the insertion plate 4 by means such as brazing, and the rear end of the bullet plate 5 is made free and is formed to have the same length as the insertion plate 4, Through-holes 6 and 6 are bored in the bullet plate 5 at positions that match the locking protrusions 2, and are positioned below the base of the inserter 3, that is, the free portion of the bullet plate 5, and the clasp main body 1 A press plate 16 is installed on the lower surface of the free rear end of the bullet plate 5 by positioning it at the opening of the dovetail hole 1b, and the press plate 16 is inserted into the square-shaped opening 3a of the inserter 3. accommodate. The pressing plate 16
By pressing , the bullet plate 5 is lifted and the through holes 6 and 6 are formed so as to be removed from the locking protrusions 2 and 2.

A ring 7 is placed on the outside of the closing part of the clasp main body 1 at a necessary location.
A ring 8 is provided at a necessary location outside the closed part of the inserter 3.
are provided, and a necklace 9 is connected to the clasp main body 1 and the inserter 3 via the rings 11 and 12 to these rings 7 and 8. Reference numeral 13 in the figure is the surface portion of the clasp main body 1, and the surface portion 13 has a pattern 10.
At the same time, ornaments 15 such as pearls and diamonds are fixed. In addition, on the surface portion 14 of the inserter 3,
A pattern 10 that harmonizes with the pattern 10 applied to the surface portion 13
is applied, and ornaments 15 such as pearls and diamonds are also fixed on the pattern 10.

As mentioned above, the present invention consists of a box-shaped clasp main body 1
A locking protrusion 2 is provided above the inner surface of the bottom wall of the clasp main body 1, an insertion plate 4 is provided on the inserter 3 in the opening of the clasp main body 1, and a bullet plate has a tip attached to the tip of the insertion plate 4. 5 is inserted, through-holes 6 and 6 are bored in the free part of the bullet plate 5 at positions that match the locking protrusions 2, and the inserter is brought into contact with the lower part of the free end of the bullet plate 5. 3 is provided with a pressing plate 16, the pressing plate 16 is pushed from below against the elastic force of the bullet plate 5, the bullet plate 5 is lifted, and the locking protrusions 2 and 2 are inserted through the through holes 6 and 6. Since it is formed so that it can be removed, the locking protrusions 2 and 2 and the through holes 6 and 6 of the bullet plate 5 are
All of the locking and detachment can be performed within the clasp main body 1, which improves the external appearance and the ornaments 15 fixed to the surface portion 13 of the clasp main body 1 and the surface portion 14 of the inserter 3. You can increase the decorative beauty of 15. In addition, since the press plate 16 is pressed on the back surface of the surface parts 13 and 14, the bullet plate 5 is lifted, and the protrusion 2 is removed from the through hole 6, the inserter 3 is pulled, so that the operation can be performed smoothly without any resistance. , the inserter 3 can be separated from the clasp main body 1. In addition, the clasp main body 1
When connecting the inserter 3 to the clasp body 1, when inserting the insertion plate 4 and the bullet plate 5 into the openings of the cross-shaped hole 1a and the dovetail-shaped hole 1b, respectively, press the pressing plate 16 while inserting the insertion plate 4 and the bullet plate 5. Locking protrusions 2 and 2 and bullet plate 5
Since there is no frictional resistance between the protrusions 2 and the protrusions 2, the protrusions 2 can be smoothly engaged or disengaged from each other, thereby preventing wear and tear on the protrusions 2 and 2, ensuring a secure engagement, and causing no rattling or noise. Therefore, when the clasp main body 1 and the insertion plate 3 are connected or separated, the neckless user does not get nervous. Moreover, it is easy to operate, with clasp main body 1 and inserter 3.
The connection is also secure, so you won't lose your netskuresu. Further, since no other object comes into contact with the locking protrusion 2, the through hole 6, and the locking portion, the locking state of both is reliable.
