DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener and a strapping device using the fastener.

[0002]

2. Description of the Related Art A common means of adjusting the length of a string is to connect portions of a desired length. Especially for decorative items, as seen in decorative strings and wrapping strings for fibrous materials,
Knotting means are often used. However, knotting at the correct length requires technical skill, and inevitable problems such as deformation of the string, length adjustment, and wear.

[0003] In the case of ornaments using chains, such as necklaces and eyeglass chains, latching with a catch is generally used. However, the catch is located out of sight and locking is difficult.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fastener and a strapping device which are easy to assemble.

Another object of the present invention is to provide a stopper which can easily and securely hold the string member.

Still another object of the present invention is to provide durability,
It is an object of the present invention to provide a stopper and a string fastening device having excellent wear resistance.

[0007]

In order to solve the above-mentioned problems, a stopper according to the present invention includes an outer shell and an elastic body. The outer shell has a hole and a hollow portion. The hole is
The outer shell body surface communicates with the hollow portion. The elastic body is
It is an O-ring having a through hole, and is built in the hollow part, and its outer periphery is in pressure contact with the inner wall surface of the hollow part. The through-hole communicates with the hole.

As described above, in the stopper according to the present invention, since the elastic body is an O-ring shaped member,
The hooking means using a wire or the like can be hooked and introduced into the outer shell. Therefore, the elastic body can be easily introduced into the outer shell without requiring a complicated process such as filling with a synthetic resin.

The fastener according to the present invention is mainly used for hanging a string. The outer shell according to the present invention has a hole and a hollow portion, and the hole communicates from the outside of the outer shell to the hollow portion. Therefore, the string can be introduced into the inside of the outer shell through the hole.

[0010] The stopper according to the present invention has an elastic body, the elastic body has a through hole, and is built in the hollow part.
The through hole of the elastic body communicates with a hole provided in the outer shell. Therefore, the string introduced into the outer shell through the hole of the outer shell can be guided to the through hole of the elastic body. In this case, by appropriately selecting the inner diameter of the string and the inner diameter of the through hole of the elastic body, the elasticity of the elastic body is used to generate frictional resistance on the string passing through the through hole, and the string is removed. Can be hooked to any length.

In addition, since the elastic member made of the O-ring member is used in the stopper, not only the elasticity of the elastic member but also the compressive force received by the elastic member from the inner wall surface of the outer shell member can be used to form the string member. Can be held. Therefore, a high holding force can be obtained.

The adjustment of the length of the string member is performed by shifting at least one of the string member and the stopper. In this case, in the stopper according to the present invention, since an elastic body made of an O-ring member is used, a commercially available O-ring can be selected and used as the elastic body. Such an O-ring is excellent in durability, abrasion resistance, etc., and is sufficiently used in this type of strapping device in which the string-shaped member must be moved inside the elastic body for length adjustment. High durability and abrasion resistance can be ensured.

Other objects, configurations and advantages of the present invention will be described in more detail with reference to the accompanying drawings which are embodiments.

FIG. 1 is a sectional view of a fastener according to the present invention. As shown in the figure, the stopper 1 according to the present invention is
An outer shell 10 and an elastic body 21 are included. The outer shell 10 has holes 15 and 16 and a hollow portion 13. The holes 15 and 16 lead from the outside of the outer shell 10 to the hollow portion 13. Outer shell 1
0 can be formed using various materials such as metals, alloys, plastics, and ceramics. The outer surface of the outer shell 10 can be decorated by plating or the like. Or
Engraving may be applied. The shape of the outer shell 10 is arbitrary. In the embodiment, the outer shell 10 is spherical.

The elastic body 21 has a through hole 22 and is built in the hollow portion 13, and the through hole 22 communicates with the holes 15 and 16. The inner diameter D2 of the through hole 22 of the elastic body 21 is smaller than the inner diameter D1 of the hole 15 or 16 of the outer shell 10. The elastic body 21 can be made of rubber, silicon rubber, or the like. The elastic body 21 is an O-ring shaped member having a through hole 22. A hooking means using a wire or the like can be hooked on the elastic body 21 formed of the O-ring member, and can be introduced into the outer shell 10. Therefore, the elastic body 21 can be easily introduced into the outer shell 10.

As is apparent from FIG.
In the inside of the hollow portion 13, the outer periphery is pressed against the inner wall surface of the hollow portion 13. Therefore, it is obvious that the elastic body 21 formed of the O-ring member receives a compressive force from the inner wall surface of the hollow portion 13 over the entire circumference. It is also obvious that the elastic body 21 made of an O-ring member has an outer diameter larger than the inner diameter of the hollow portion 13 of the outer shell 10 before being introduced into the outer shell 10.

1 can cause frictional resistance, and the string member 31 can be hooked to an arbitrary length.

Moreover, since the elastic member 21 made of an O-ring member is used in the stopper 1, not only the elastic force of the elastic member 21 but also the compressive force that the elastic member 21 receives from the inner wall surface of the outer shell 10 is used. Thereby, the string member 31 can be held, so that a moderately high holding force can be obtained.

The length of the string member 31 is adjusted by shifting at least one of the string member 31 and the stopper 1 in the direction a or b (see FIG. 3). In the stopper 1 according to the present invention, since the elastic body 21 made of the O-ring member is used,
It can be selected from commercially available O-rings. Such an O
Since the ring is excellent in durability, abrasion resistance, and the like, a sufficient durability can be obtained in this type of a strapping device in which the string-shaped member 31 must be moved inside the elastic body 21 for adjusting the length.
