Abstract

PURPOSE:To save labor in the process for producing a swivel, by molding monolithically a click and the main body from a plastic such that the tip of the click may be remained outside and spaced a little away from a hook. CONSTITUTION:Taking into consideration that the tip 1' of the click 1 is pushed down with the hook 2 being moved sideways, is introduced into the hook 2 and is engaged with the inner surface of the hook 2 by the restoring resiliency of the click 1, the click 1 and the main body 3 are monolithically molded from a plastic by the injection molding in such a way that the tip 1' has a space 4 over the outer surface of the hook 2 thereby providing the desired swivel.

Mainly, the bag body and the shoulder strap of the bag 11 are used to removably connect a band or the like.

させたものもある。Conventional eggplant rings are mainly made of metal, with the main body and claws molded separately, and the claws attached to the base of the main body. The claws are generally made of leaf springs and are attached to the base of the main body by crimping.
The tip is brought into contact with the inside of the hook by its own elasticity, but in addition, the nail is pivoted to the base of the main body with a pin, the nail is biased with a leaf spring, etc., and the tip of the nail is brought into contact with the inside of the hook. There are also some that are connected to gifKal.

が必要で、製作には手数がか−る。In any case, it is conventionally necessary to assemble three parts, the main body and the pawl made of a leaf spring, or four parts: the main body, the pawl, the bead, and the biasing spring, which is time-consuming to manufacture.

そこで本発明はナス環をグラスチックで一体に成形し、

本発明を説明する。Therefore, in the present invention, the eggplant ring is integrally molded with glass,
As usual Kll! The invention eliminates the need to construct and then assemble several parts.The present invention will now be described with reference to the drawings.

ＨＫナス狽の各半部を成形する鋳腔６′。FIG. 1 shows an example of a glass eggplant ring according to the present invention in a molded state, and the claw I has a main body J having seven claws at the tip.
It is bent back from the base 3' of the hook, and the toe I' overlaps the outer case of the hook with a slight spacing. In this way, an eggplant ring with the main body and claws integrated is molded using plastic.

は再びノックの内面に弾性的に当接する。ζ Next, the eggplant ring shown in Fig. 11 formed in this way is pushed down to the bottom of the white picture of the 7th vine 1 by deflecting the claw 1 to the side of the 7th vine and at the same time applying downward pressure. After this K, the claw I tries to return to the state of jt by its own elasticity, and the toe I'' is brought into elastic contact with the inner surface of the footer. The cylinder l to be connected can be inserted and removed by creating a space between the nail and the toe, and when the force is released, the toe elastically contacts the inner surface of the knock again.

先を７ツタの内面に当接させるのである。In other words, in the present invention, the nail I is molded integrally with the main body using plastic so that the toe tip overlaps the outer surface of the 7 ivy with a slight interval, and then the toe l of IK/ is placed next to the footer. The tip of the toe is brought into contact with the inner surface of the vine using the returning elastic force of the claw.

Ｋか連結が外れろ虞がある。It is possible to put the tip of the toe inside the 7-piece and mold the nail integrally with the main body using plastic, but in this case, a minimum distance of 1-11 degrees should be maintained between the tip of the toe and the inner surface of the 7-piece. It is necessary to do this, and when you put it in the 7 ivy and connect it, there is a risk that the connection will come off before you know it.

れ九特長を有する。However, in the present invention, the claws are molded integrally with the main body with the tips kept at a slight distance on the outer surface of the 7-tsuk, and then placed inside the 7-ivy at the next factory. Due to its characteristic, the toe is brought into contact with the inner surface of the footer due to the elastic return force that tends to return it to a position slightly above the outer surface of the hook. For this reason, the claw always closes the 7 vines in contact with the inner surface of the hook, and functions in the same way as conventional gold lll1l.
) Moreover, compared to conventional metal products, it has many advantages such as being able to be made in one injection molding, being lighter and heavier, and being able to mix colorants into the raw material glass to give it any desired color. It has characteristics.

The o-shaft part 10' is pivotally connected by a snug engagement.In this case, the Ω-shaped retaining part is formed by the molding method so that in addition to the elastic force of one claw, the claw C) WAN can be moved with ease. , energizes its elastic force.
