Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to improvement of an eggplant ring made of synthetic resin.

[Prior Art] Conventionally, this type of eggplant ring has been made of synthetic resin or metal, and includes a main body, a hook formed by folding back one end of the main body, and a hook formed from the other end of the main body toward the hook. A hook member that extends and is integrally provided with a claw that normally contacts the inner surface of the hook with a spring force to close the hook, and a hook member that is connected to the other end of the main body of the hook member and that fastens bands. It is known that the object is inserted into the hook of the main body by tilting the claw (Japanese Unexamined Patent Application Publication No. 47-5411, Japanese Unexamined Patent Publication No. 52617-1983, Utility Model Application No. 56-1983). - Publication No. 29311).

[Problems to be Solved by the Invention] However, the above-mentioned conventional eggplant rings made of synthetic resin have a problem in that their strength is lower than that of metal ones.

Further, if the hook member and the connecting ring are separately molded from synthetic resin, it becomes necessary to connect the two, which poses a problem in that the connecting operation is time-consuming.

Furthermore, in conventional eggplant rings, the inner surface of the end of the hook is flat, so there is a problem in that objects such as rings and keys placed inside the hook can move freely within the closed loop formed by the hook and claw. Ta.

For this reason, when carrying rings and keys, they may hang around inside the hook, or the rings or keys may hit each other, or they may make a clanking sound when they touch a desk or wall, or they may be pressed by a fingernail for some reason. If this happens, it has the disadvantage that it can easily come off carelessly.

Therefore, the present invention is intended to solve the above-mentioned conventional problems, and its purpose is to:
To provide a synthetic resin eggplant ring which causes less movement of an object within a hook, has high strength, and can be assembled simply and quickly.

[Means for Solving the Problems] The present invention is intended to achieve the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

In the present invention, the hook 2 of the hook member has a protrusion 2c that is raised inward from the inner surface between the tip portion 2a that comes into contact with the tip 1' of the hook 1 and the bent portion 2b that is bent in a folded manner. In addition, a thick reinforcing rib 13 is provided along the outer surface of the hook, and the other end of the main body 3 of the hook member is provided with an engaging portion 9 that snaps into a connecting ring (for example, a ring 10). The hook member and the connecting ring are connected to each other by snap-engaging the engaging portion to the connecting ring.

[Function] Therefore, by snap-engaging the engaging portion 9 of the hook member to the connecting ring 10, the two can be connected with one touch.

Further, the strength of the hook 9 can be improved by the thick reinforcing rib 13.

Further, when the object is placed in the hook, the object climbs over the protrusion 2c and falls to the bottom of the bent portion 2b of the hook, and its movement is restricted by the protrusion. For example, even if the claw inadvertently bends inward and the hook opens, the protrusion restricts the movement of the object, thereby preventing the object from accidentally coming off the hook.

[Example] The present invention will be described below based on an example shown in the drawings.

FIG. 1 shows an example of a plastic eggplant ring according to the present invention in a molded state, in which the claw 1 is curved and folded back from the base 3' of the main body 3 having a hook 2 at the tip.
The toe 1' overlaps the outer surface of the hook 2 at a slight distance 4. In order to mold a hook member having the main body and the claw as one body, two molds 6 and 7 are formed so that the parting line 5 shown in FIG. 2 becomes the joint of the molds. A cavity 6' in which each half of the hook member is formed on the opposing surface;
7', the two molds 6 and 7 are brought together to inject the molten raw material into the casting cavity, and then the molds 6 and 7 are opened and taken out.

In this way, the hook member shown in FIG.
Press down on the inner surface of the As a result, the claw 1 attempts to return to its original state with its own elasticity and elastically abuts the tip 1' against the inner surface of the hook, resulting in the completed state shown in FIG. By creating a space between the toes, the ring 8 as the object to be connected can be taken in and out, and when the force is released, the toes will come into elastic contact with the inner surface of the hook again.

On the other hand, as shown in FIG. 4, the hook 2 extends in a J-shape from one end of the main body, and has a distal end 2a that comes into contact with the tip 1' of the claw 1, and a bent part that is bent in a folded shape at the center. 2b, and between the tip 2a and the bent part 2b, a protrusion 2c protruding inward from the inner surface in a substantially chevron shape is integrally provided at a position where movement of the claw 1 is not hindered, This projection 2c narrows the distance between the opposing surfaces of the inner surface of the bent portion 2b to be approximately equal to the thickness of the ring 8.

Therefore, when the claw 1 is pressed to create a space between the inner surface of the tip 2a of the hook 2 and the toe 1', and the ring 8 is inserted through this space, the ring 8 will fit into the protrusion 2c.
When moving along the slope on one side and passing the top of the protrusion 2c, the bending portion 2b moves along the slope on the other side.
fall to the bottom of In this way, the ring 8
Once the ring 8 falls into the interior of the ring 8, unnecessary movement of the ring 8 is restricted by the protrusion 2c.

Furthermore, an Ω-shaped engagement portion 9 is integrally formed on the inner surface of the curved folded portion 1″ between the claw and the base of the main body.
The shaft portion 10' of a D-shaped ring 10, which serves as a connecting ring for connecting individual belts and bands, is pivoted by snap engagement. The D-shaped ring 10 is integrally molded from plastic separately from the hook member. In this case, Ω
In addition to the elastic force of the pawl due to the molding method, the shaped engaging part is designed to have spring properties that allow the pawl to open and close.
It has the effect of imparting that elastic force.

On the other hand, FIG. 6 shows another embodiment of the present invention, in which an enlarged head 1 is provided at the tip as the engaging portion.
A two-split leg 12 etc. having a diameter of 1 is provided integrally protruding backward from the base 3', and is opened in a D-shaped ring etc., and the enlarged head is reduced in diameter and passed through the hole, and the enlarged head returns to its original state after coming out of the hole. By returning to the state, the D-shaped ring may be pivotally mounted around the leg 12.

In actual use, reinforcing ribs 13 are integrally provided on the outer surfaces of the main body and the claws to provide strength.

Incidentally, the hook member and the connecting ring may be colored in any desired color by mixing a pigment with the raw materials.

Further, the connecting ring is not limited to a D-shaped ring, but may be a C-shaped ring.

Furthermore, the object to be connected to the hook is not limited to the triangular ring 8, but may also be a circular ring or other objects such as a key.

[Effects of the Invention] As explained above, according to the present invention, the movement of the object can be regulated by the projection, so that the projection can prevent unnecessary movement of the object. For example, when carrying the object, it is quiet because it does not hang around unnecessarily, and even if the hook inadvertently bends inward and the hook opens, the protrusion prevents the object from moving. Therefore, it is difficult to miss the target object.

Further, since the hook of the hook member is provided with thick reinforcing ribs along its outer surface, it is possible to provide a synthetic resin eggplant ring with high rigidity.

Further, since the other end of the main body of the hook member is provided with an engaging portion that snaps into engagement with the connecting ring, the connecting operation with the connecting ring can be performed easily and quickly.
