At the other end of the base of the hook member, there is provided an engaging portion for snap-engaging with the connecting ring, and the toe of the claw portion including this engaging portion is placed on the outer surface of the hook portion. The base and the claw were integrally molded of synthetic resin so as to overlap with a slight gap. After the molding, the toe of the claw was pressed into the hook while being warped to the side of the hook, and the claw was brought into contact with the inner surface of the hook by the elastic restoring force of the claw.

[0004] After that, the connecting ring is snap-engaged with the engaging portion of the hook member to connect the hook member and the connecting ring to each other.

[0005]

However, in the above-mentioned conventional eggplant ring, it is troublesome to press the toe of the claw portion while bending it to the side of the hook portion after molding, and to insert the toe into the hook portion. In addition, since the hook member and the connecting ring must be connected thereafter, there is a problem that the assembly of the eggplant ring is troublesome.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to reduce the number of assembling steps, making the assembling work simple and quick. It is an object of the present invention to provide an eggplant ring made of synthetic resin that can be used.

And a connecting ring 30 connected to the hook member 20. As shown in FIGS. 1 to 6, the hook member 20 is roughly divided into a base 40, a hook 50 extending in a folded shape from one end of the base 40, and a hook 50 extending from the other end of the base 40. A claw portion 60 extending in a folded shape toward 50 and having a toe 61 at a free end tip thereof faces the inner surface of the hook portion 50 and always closes the hook portion 50.

More specifically, at the other end of the base portion 40, an engaging portion 70 for snap-engaging with the connecting ring 30 is formed, and the toe of the claw portion 60 including this engaging portion 70 is formed. The base portion 40 and the claw portion 60 have an appropriate elasticity and rigidity, and are integrally formed of a thermoplastic resin such as POM, for example, so that 61 is overlapped on the inner surface of the hook portion 50 with a slight interval 80 therebetween. I have.

As shown in FIGS. 1 to 6, the base 40 has a triangular frame shape as a whole. More specifically, the base 40 is composed of a horizontal bar 41 extending in one horizontal character, and a pair of left and right cross bars 42, 42 extending diagonally from the left and right ends of the horizontal bar 41 toward each other. ing.
As shown in FIG. 1, the hook portion 50 is
The J-shaped section extends upward from the lower end of the intersection of 42. On the inner surface of the distal end of the hook portion 50, a step portion 51 that engages with the toe 61 of the claw portion 60 is formed.

[0014] As shown in FIG.
From the horizontal bar 41 of 40, it extends while bending downward in a U-shaped cross section, and its thickness is gradually reduced so as to be easily bent. On the inner surface of the engaging portion 70, a protruding portion 71 which is curved in a semicircle and has
Are formed to prevent the connection ring 30 from coming off from the engagement portion 70. The inner diameter of the inner peripheral surface of the engaging portion 70 is set smaller than the inner diameter of the inner peripheral surface of the curved portion of the hook portion 50.

As shown in FIGS. 1 to 7, the claw portion 60 has a triangular plate shape substantially equal to the base portion 40. On the outer surface of the claw portion 60, a plurality of, in this case, three, ribs 62 for preventing slippage are formed, which are raised in a semicircular cross section. On the other hand, as shown in FIGS.
It is substantially D-shaped. More specifically, the U-shaped frame portion 31 for fastening the bands, the both ends are connected to the inner surfaces of both open lower ends of the frame portion 31, respectively, and are snap-engaged with the engagement portion 70 of the hook member 20. And is integrally formed of a rigid thermoplastic resin such as POM.

As shown in FIG. 1, the shaft portion 32 has a cylindrical shape, and its outer diameter is set to be larger than the inner diameter of the engaging portion 70 of the hook member 20. The outer diameter of the shaft portion 32 is set to be equal to the inner diameter of the engaging portion 70 of the hook member 20.
Forming a projection or the like 32 outer peripheral surface of the large maximum outer diameter of the shaft portion 32
May be.

Next, a mold for forming the hook member 20 will be described with reference to FIG. As shown in FIG. 8, the hook members 2 are provided on the opposing surfaces of the split molds 90 and 91 so that the parting line 100 shown in FIG.
The cavities 92 and 93 for molding the respective half halves of the “0” are formed. Then, the molding process is a mold clamping process of the two dies 90, 91, an injection process of injecting the molten resin into the cavities 92, 93 of the two dies 90, 91 after the mold clamping, and after the injection of the molten resin, Cooling process for cooling both molds 90 and 91 and hardening the molten resin in cavities 92 and 93, mold opening process for opening both molds 90 and 91 after cooling, and molding from open molds 90 and 91 Rear hook member 20
And a take-out process.

After molding, as shown in FIG.
The eggplant ring 10 is assembled by connecting the and the connection ring 30 to each other. First, as shown in FIG.
By pressing the toe 61 of the 60 with the shaft 32 of the connecting ring 30, the claw 60 is tilted, and the shaft 32 is introduced into the hook 50 in the open state.

Thereafter, the shaft portion 32 of the connecting ring 30 is slid toward the engaging portion 70 of the hook member 20, as indicated by an arrow in FIG. When the shaft portion 32 of the connecting ring 30 is slid,
The shaft portion 32 is engaged with the raised portion 71 on the inner surface of the engaging portion 70. Here, when the shaft portion 32 is strongly pushed into the engaging portion 70, the raised portion 71 is pushed by the shaft portion 32, and the diameter of the engaging portion 70 is increased, so that the shaft portion 32 is brought into contact with the raised portion 71. It passes through the gap with the inner surface of the base 40. When the shaft portion 32 passes through the space between the raised portion 71 and the inner surface of the base portion 40, the engaging portion 70 is restored by the elastic force of the resin, so that the shaft portion 32 snaps into the engaging portion 70. Put in.

When the shaft portion 32 fits into the engaging portion 70 in this manner, the shaft portion 32 does not come off from the engaging portion 70 due to the presence of the raised portion 71, and the hook member 20 and the connecting ring 30 are mutually connected. Be linked. The connecting ring 30 is rotatably supported by the hook member 20 around the shaft portion 32. In addition, since the outer diameter of the shaft portion 32 is set to be larger than the inner diameter of the engaging portion 70 of the hook member 20, the inner peripheral surface of the engaging portion 70 is pushed by the outer peripheral surface of the shaft portion 32, and is slightly enlarged. Maintain the diameter. For this reason, the toe 61 of the claw portion 60 connected to the engaging portion 70 elastically abuts the step portion 51 on the inner surface of the distal end of the hook portion 50, and the hook portion 50 is normally closed.

At the time of use, although not shown, for example, a shoulder band or the like of a bag is fixed to the connecting ring 30. On the other hand, for example, a D ring or the like is fixed to the bag body as an object, and the hook member 20 is attached. By attaching to and detaching from the D ring, the shoulder band can be attached and detached. More specifically, the claw 60 of the hook member 20 is tilted by pressing the claw 60 with the D ring. When the claw portion 60 is tilted, the toe 61 is separated from the step portion 51 of the hook portion 50, so that the hook portion 50 is opened. Thus, the D ring is inserted into the hook 50 while the hook 50 is being opened. When the D ring is inserted into the hook portion 50, the claw portion 60 is restored by the elastic force of the resin, and the toe 61 comes into contact with the step portion 51 of the hook portion 50, so that the hook portion 50 is again closed. Return to.

The use of the eggplant ring 10 is not limited to this, but can be used for various purposes. On the other hand, in the embodiment shown in the drawings, the hook member 20 is formed in a plane triangle shape. Also, on the outer surface of the claw portion 60,
Although a plurality of raised ribs 62 are formed, the present invention is not limited to this, and a concave groove may be formed.

Further, the raised portion 71 is formed on the inner surface of the engaging portion 70. However, the present invention is not limited to this, and the inner surface of the engaging portion 70 is formed to have an Ω-shaped cross section so that the shaft portion 32 of the connecting ring 30 can be removed. May be prevented.
The connecting ring 30 is not limited to the substantially D-shape, but may be formed in a triangle shape, and may be made of metal as well as resin.
