More specifically, the base 40 is composed of a horizontal bar 41 extending in a single horizontal line, and a pair of left and right intersecting bars 42, 42 extending obliquely from the left and right ends of the horizontal bar 41 toward each other. Has been done. As shown in FIG. 1, the hook portion 50 extends upward in a J-shaped cross section from the lower ends of the cross bars 42. A step portion 51 that engages with a toe 61 of the hook 60 is formed on the inner surface of the tip of the hook 50.

As shown in FIG. 1, the engaging portion 70 extends downward from the horizontal bar 41 of the base portion 40 while bending in a U-shaped cross-section, and is gradually reduced in thickness so as to be easily bent. There is. Then, the inner surface of the engaging portion 70 is curved in a semicircular shape, and a protruding portion 71 that is raised in a chamfered shape is formed between the engaging portion 70 and the claw portion 60, and the connecting ring 30 comes off from the engaging portion 70. Is being prevented. 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 that is substantially the same as the base portion 40. On the outer surface of the claw portion 60, a plurality of ribs 62 ... On the other hand, the connecting ring 30 is substantially D-shaped as shown in FIGS. More specifically, the U-shaped frame portion 31 for fastening the bands and the both end portions are respectively connected to the inner surfaces of both open lower ends of the frame portion 31 and snap-engaged with the engaging portion 70 of the hook member 20. The shaft 32 is formed integrally with 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 itself is set to be equal to the inner diameter of the engaging portion 70 of the hook member 20, and a protrusion or the like is formed on the outer peripheral surface of the shaft portion 32 to obtain the maximum outer diameter of the shaft portion 32. May be increased. Conversely, a protrusion or the like may be formed on the inner peripheral surface of the engaging portion 70 to reduce the minimum inner diameter of the engaging portion 70.

Next, a mold for molding the hook member 20 will be described with reference to FIG. As shown in FIG. 8, one half of the hook member 20 is provided on each of the facing surfaces of the mold halves 90 and 91 so that the parting line 100 shown in FIG. Molding cavities 92, 93 are formed. Then, the molding process includes a mold clamping process of both molds 90 and 91, an injection process of injecting molten resin into the cavities 92 and 93 of both molds 90 and 91 after mold clamping, and an injection process of molten resin, Cooling process for cooling both molds 90, 91 to cure the molten resin in the cavities 92, 93, mold opening process for opening both molds 90, 91 after cooling, and molding from the open molds 90, 91 And a take-out step for taking out the hook member 20 afterward.

After molding, as shown in FIG. 9, the hook member 20 and the connecting ring 30 are connected to each other to assemble the eggplant ring 10. First, as shown in FIG. 9, the toe 61 of the claw 60 of the hook member 20 is pressed by the shaft 32 of the connecting ring 30 to tilt the claw 60 and move it into the hook 50 in the open state. Insert the shaft 32.

After that, the shaft portion 32 of the connecting ring 30 is slid toward the engaging portion 70 of the hook member 20, as shown by the arrow in FIG. When the shaft portion 32 of the connecting ring 30 is slid, the shaft portion 32 engages with the raised portion 71 on the inner surface of the engagement portion 70. Here, when the shaft portion 32 is strongly pushed toward the inside of the engaging portion 70, the protruding portion 71 is pushed by the shaft portion 32 and the engaging portion 70 expands in diameter, whereby the shaft portion 32 is raised. It passes through the space between 71 and the inner surface of the base 40. Then, when the shaft portion 32 passes through the space between the raised portion 71 and the inner surface of the base portion 40, the engagement portion 70 is restored by the elastic force of the resin, so that the shaft portion 32 snaps into the engagement portion 70.

Are connected. The connecting ring 30 is rotatably supported by the hook member 20 around the shaft portion 32. Further, 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 slightly expands. Maintain the diameter. For this reason, the toe 61 of the claw 60 connected to the engaging portion 70 elastically abuts the step 51 on the inner surface of the tip of the hook 50, and the hook 50 is normally closed.

At the time of use, although not shown, for example, a shoulder band of a bag or the like is fixed to the connecting ring 30, while, for example, a D ring or the like is fixed to the bag body as a target. The shoulder band can be attached / detached by attaching / detaching to / from the D ring. More specifically, by pressing the claw portion 60 of the hook member 20 with the D ring, the claw portion 60 is tilted. When the claw portion 60 tilts, the toe 61 of the claw portion 60 separates from the stepped portion 51 of the hook portion 50, so that the hook portion 50 is opened. Thus, while opening the hook portion 50, the D ring is inserted into the hook portion 50. When the D ring is inserted into the hook 50, the claw 60 is restored by the elastic force of the resin, and the toe 61 of the claw 60 abuts the step 51 of the hook 50, and the hook 50 is closed again. Return to the state.

The application of the eggplant ring 10 is not limited to this, and can be used for various applications. On the other hand, in the embodiment shown in the drawings, the hook member 20 is formed in a flat triangle shape, but the hook member 20 is not limited to this, and may be a single plane shape or the like. Further, although a plurality of semi-circular raised ribs 62 are formed on the outer surface of the claw portion 60, the present invention is not limited to this, and a concave groove may be formed.

Further, although the raised portion 71 is formed on the inner surface of the engaging portion 70, the present invention is not limited to this. You may prevent it. Further, the connecting ring 30 is not limited to being substantially D-shaped, but may be formed in a triangular shape, and may be made of metal instead of resin.
