Among the eggplant rings described in the patent document, the fastener using the elastic wire has the advantage that the number of parts is small, the structure is simple, and the fastener can be manufactured at low cost, as compared with the fastener using the slide method. So, there are the following inconveniences.

That is, the mounting body attached to the arc-shaped hook portion of the eggplant ring often uses an annular ring member so that it can be easily attached to the hook portion. Then, in the case of this kind of conventional eggplant ring, when some external force is applied to the ring member which is the mounting body and the ring member moves, the ring member located on the outside is the same as the operation state when the ring member is attached to the fastener. In addition, it works to push the fastener open from the outside, and as a result, a problem occurs in which the ring member attached to the hook portion comes off.

The present invention has been made in view of the above circumstances, and is attached to a hook portion of an eggplant ring in which a fastener made of an elastic wire is provided on the eggplant ring body even if the ring member is moved by applying some external force. It is intended to provide an eggplant ring capable of avoiding a problem that the ring member comes off.

In the present invention, to be described with reference numerals used in Examples, the eggplant ring 1 is provided with a fastener 20 made of an elastic wire on the eggplant ring body 2, and the ring member 10 is detachably attached to the eggplant ring body 2. In
The eggplant ring main body 2 has a pair of leg portions 4 and 5 provided with an opening 3 for inserting the ring member 10, and a hook portion in which both ends thereof are connected to the lower portions 4b and 5b of the leg portions 4 and 5. With 6
The distance T between the tip portions 4a and 5a of the pair of legs 4 and 5 and the fastener 20 and the maximum inner diameter t of the inner diameters of the ring member 10 is T> t. It is an eggplant ring 1.

The eggplant ring of the present invention configured as described above will be described with reference to the drawings of Examples. In the eggplant ring 1 having the configuration shown in FIG. 1, for example, the ring member 10 holding the key K is shown in FIG. As shown in the above, it is attached to the eggplant ring main body 10.

That is, as shown in FIG. 3, the ring member 10 holding the key K is inserted through the opening 3, and the fastener 20 is pressed against the elastic urging force by the ring member 10 (FIG. 4). As a result, as described above, the ring member 10 is attached to the eggplant ring main body 10 (FIG. 2).

As shown in FIG. 5, in the eggplant ring 1 of the present invention, since T> t between the interval T and the maximum inner diameter t of the inner diameter of the ring member 10, some external force is applied to the ring member 10. Even if the ring member 10 moves in addition to the ring member 10, the ring member 10 cannot exceed the tip portion 5a of the leg portion 5, as shown by the portion A in FIG. As a result, unlike the structure (FIGS. 8 to 10) that does not satisfy T> t, which will be described later, it is possible to prevent the ring member 10 from coming off from the hook portion 6.

On the other hand, as shown in FIG. 8, when T> t is not satisfied between the interval T and the maximum inner diameter t of the inner diameter of the ring member 10, for example, when T <t, the ring member When some external force is applied to the 10 and the ring member 10 moves, the ring member 10 exceeds the tip portion 5a of the leg portion 5, as shown in FIG. Therefore, the ring member 10 beyond the tip portion 5a of the leg portion 5 is inserted through the opening 3 and presses the fastener 20 against the elastic urging force (FIG. 10), and the hook portion 6 and the hook portion 6 and the like have been used so far. The ring member 10 locked to the leg portion 5 connected to the eggplant ring body 2 is separated from the eggplant ring main body 2.

As described above, according to the present invention, it is possible to obtain an eggplant ring capable of avoiding a problem that the ring member attached to the hook portion comes off even if the ring member is moved by applying some external force. ..

Hereinafter, examples of the present invention will be described with reference to the drawings.

In the eggplant ring 1 of this example, as shown in FIGS. 1 to 7, the eggplant ring 1 is provided with a fastener 20 made of an elastic wire on the eggplant ring body 2, and the ring member 10 is detachably attached to the eggplant ring body 2. Is.

The eggplant ring main body 2 has a pair of leg portions 4 and 5 provided with an opening 3 for inserting the ring member 10, and a hook portion 6 whose both ends are connected to the lower portions 4b and 5b of the leg portions 4 and 5. Be prepared. In the eggplant ring main body 2 of this example, a hole 7 for inserting the strap 30 is formed in the upper part of the leg portion 4.

Similar to the fastener described in Patent Document 1, the fastener 20 of this example uses a substantially U-shaped elastic wire having both ends bent inward, and has a length of one side and the other side of the substantially U-shape. On the other hand, when the end portion of the fastener is engaged with the recessed hole 8 of the eggplant ring main body 2, it is configured to be rotationally urged in one direction.

In the case of this example, the fastener 20 is supported by one leg 4 of the pair of legs 4 and 5 so that one end 20a of the fastener 20 can be rotatably urged, and the other end 20b is supported. It is provided so as to be in contact with the other leg portion 5. When the other end 20b of the fastener 20 comes into contact with the other leg 5, the lower part of the leg 5 is held so that the other end 20b of the fastener 20 fits well and is securely abutted. A groove 6a is provided in the nearby hook portion 6.

Further, in the eggplant ring 1 of this example, between the distance T between the tip portions 4a and 5a of the pair of legs 4 and 5 and the fastener 20 and the maximum inner diameter t of the inner diameters of the ring member 10. In addition, it has a relationship that T> t.

As described above, since the eggplant ring 1 of this example has T> t between the interval T and the maximum inner diameter t of the inner diameters of the ring member 10, some external force is applied to the ring member 10 to move. However, the ring member 10 cannot exceed the tip portion 5a of the leg portion 5. This makes it possible to prevent the ring member 10 from coming off from the hook portion 6.

In the eggplant ring 1 of this example, the ring member 10 has a circular shape, but may have an elliptical shape. In this case, the major axis of the elliptical shape is the maximum inner diameter t. Further, in the above embodiment, the case where the ring member 10 cannot exceed the tip portion 5a of the leg portion 5 has been described as an example, but it goes without saying that the same applies to the case of the tip portion 4a of one leg portion 4. is there. As described above, the present invention is not limited to those shown in the above examples, and can be appropriately modified to contribute to the achievement of the object of the present invention.

The present invention avoids the problem that the ring member attached to the hook portion comes off even if some external force is applied to the ring member in the eggplant ring provided with the fastener made of the elastic wire on the eggplant ring main body. It can be suitably used as a possible eggplant ring.
