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 cord member is to connect portions of a desired length. In particular, in the case of decorative articles, knotting means are frequently used as seen in decorative cord members, wrapping cord members, and the like in the case of fibrous materials. But,
To tie a knot to the correct length requires technical skills, and inevitable problems such as deformation of the cord member, 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 stopper and a tying device which can easily and surely hold a tying member.

[0005] Another object of the present invention is to provide a stopper and a tying device that can arbitrarily and easily adjust the loop formed by the tying member.

[0006]

In order to solve the above-mentioned problems, a stopper according to the present invention includes an outer shell, an elastic body, and a strap. The outer shell has a hole and a hollow portion. The number of the holes is two, and each of the holes leads from the outside of the outer shell to the hollow portion. The hollow portion,
The inner surface is spherical.

[0007] The elastic body has a through hole and is built in the hollow part, and the outer periphery thereof is pressed against the inner wall surface of the hollow part. The through-hole communicates with the hole.

[0008] The strap is projected from an outer surface of the outer shell.

As described above, in the fastener according to the present invention, the outer shell has the hole and the hollow portion, and the hole communicates from the outside of the outer shell to the hollow portion. Therefore, hooking means using a wire or the like can be hooked on the elastic body, and can be 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 elastic body is housed inside the hollow portion, and its outer periphery is pressed against the inner wall surface of the hollow portion. In this case, since the inner surface of the hollow portion of the outer shell body in which the elastic body is housed is spherical, the elastic body fits approximately on the maximum diameter of the spherical hollow portion.
In the spherical hollow portion, when the elastic body attempts to move in both directions from the top of the diameter to the smaller diameter, a force is applied to the elastic body from the inner surface of the spherical hollow portion in a direction that hinders the movement. The elastic body is stably held on the substantially maximum diameter of the spherical hollow portion.

[0011] The stopper according to the present invention is mainly used for retaining a string member. The shell according to the present invention has a hole,
A hollow portion, and the hole communicates from the outside of the outer shell to the hollow portion. Therefore, one end of the string member can be introduced into the inside of the outer shell through the hole.

Moreover, the stopper according to the present invention includes a strap, and the strap is projected from the outer surface of the outer shell.
Therefore, through the hole of the outer shell, one end of the string member is introduced into the inside of the outer shell, and the other end of the string member is connected to the strap, and between the entrance of the hole of the outer shell and the strap. And a loop of a string member can be made.

Further, 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 member introduced into the outer shell can be guided to the through-hole of the elastic body through the hole of the outer shell. In this case, by appropriately selecting the diameter of the string member and the inner diameter of the through hole of the elastic body, utilizing the elasticity of the elastic body, causing frictional resistance to the string member passing through the through hole, The string member can be held at any position. Since the other end of the string member is connected to the strap, by adjusting the holding position of the strap member, between the entrance of the hole of the outer shell and the strap provided on the outer surface of the outer shell. The resulting loop of the cord member can be easily adjusted to be large or small.

In addition, since the elastic body is built in the hollow part and its outer periphery is pressed against the inner wall surface of the hollow part, not only the elasticity of the elastic body but also the elastic body is formed by the inner wall surface of the outer shell. The string member can be held by the compressive force received from the member. Therefore, a high holding force can be obtained.

The length of the string member is adjusted by shifting at least one of the string member and the stopper. When the string member or the stopper is shifted, a force in the shifted direction is applied to the elastic body. The direction of this force coincides with the direction in which the elastic body is moved from above the maximum diameter to a direction in which the diameter becomes smaller. In this case, in the stopper according to the present invention, since the inner surface of the hollow portion of the outer shell body in which the elastic body is stored has a spherical shape, the elastic body tends to move from the top in the diameter to both directions in which the diameter decreases. In this case, a force is applied from the inner surface of the spherical hollow portion to the elastic body in a direction that prevents the elastic body from moving. For this reason, the elastic body is stably held at almost the maximum diameter of the spherical hollow portion despite the shifting operation of the string member or the stopper.

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

[0017]

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, an elastic body 21, and a strap 12 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. The hollow portion 13 has a spherical inner surface. 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. In the embodiment, the elastic body 21 is an O-ring 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.

The strap 12 protrudes from the outer surface of the outer shell 10. The strap 12 shown in the embodiment has a ring portion at the tip. The ring portion is provided at the other end of a member having one end fixed to the outer surface of the outer shell 10.

FIG. 2 is a perspective view of a strapping device using the fastener according to the present invention, and FIG. 3 is a sectional view of the strapping device shown in FIG. The illustrated tying device includes a tying member 1 and a tying member 31. The stopper 1 is the stopper according to the present invention shown in FIG.

One end of the string member 31 is guided from the outside of the outer shell 10 through the hole 15 into the hollow portion 13 of the outer shell 10, and the through hole of the elastic body 21 built in the hollow portion 13 is formed. Part 22
Penetrate through. One end of the string member 31 is further guided outside through the hole 16 of the outer shell 10. The other end of the string member 31
It is tied to the strap 12. The string member 31 is a chain,
It can be constituted by fibers or a combination thereof.

The stopper 1 is the stopper according to the present invention shown in FIG. 1 and has an elastic body 21 built in the hollow portion 13 of the outer shell 10. Therefore, by appropriately selecting the outer diameter of the string member 31 and the inner diameter of the through hole 22 of the elastic body 21, the string member 3 passing through the through hole 22 by utilizing the elasticity of the elastic body 21.
1 can cause frictional resistance, and the string member 31 can be hooked to an arbitrary length.

The elastic body 21 is housed inside the hollow portion 13, and the outer periphery thereof is pressed against the inner wall surface of the hollow portion 13. In this case, the hollow portion 1 of the outer shell 10 in which the elastic body 21 is stored
In No. 3, since the inner surface has a spherical shape, the elastic body 21 fits almost on the maximum diameter of the spherical hollow portion 13. In the case where the elastic body 21 attempts to move from the upper side to the lower side in the spherical hollow section 13, the elastic body 21 is moved from the inner surface of the spherical hollow section 13 to the elastic body 21. Is applied, the elastic body 21 is stably held on the substantially maximum diameter of the spherical hollow portion 13.

Moreover, the stopper 1 according to the present invention includes the strap 12, and the strap 12 is projected from the outer surface of the outer shell 10. Therefore, through the hole 15 of the outer shell 10,
Into the inside, one end of the string member 31 is introduced, and the other end of the string member 31 is connected to the string stopper 12, so that the string member is located between the entrance of the hole 15 of the outer shell 10 and the string stopper 12. You can make 31 rings.

The size of the loop of the string member 31 that is generated between the string member 12 and the string stopper 12 can be easily adjusted to be large or small.

Moreover, since the elastic body 21 is built in the hollow portion 13 and the outer periphery thereof is pressed against the inner wall surface of the hollow portion 13, not only the elasticity of the elastic body 21 but also the elastic body 21 By the compressive force received from the inner wall surface of the shell 10,
The string member 31 can be held. For this reason, a high strap holding force is obtained.

The length of the string member 31 is adjusted by moving at least one of the string member 31 and the stopper 11 in the direction a.
Alternatively, the shift is performed in the direction b (see FIG. 3). When the string member 31 or the stopper 1 is shifted, a force in the shifted direction is applied to the elastic body 21. The direction of this force coincides with the direction in which the elastic body 21 is moved from above the maximum diameter to a direction in which the diameter becomes smaller. In this case, in the stopper 1 according to the present invention, the hollow portion 13 of the outer shell 10 in which the elastic body 21 is housed has a spherical inner surface.
When trying to move in both directions from the top of the diameter to the smaller diameter, the elastic body 21 is removed from the inner surface of the spherical hollow portion 13.
, A force is applied in a direction that hinders the movement. For this reason, despite the shifting operation of the string member 31 or the stopper 1,
The elastic body 21 is stably held on almost the maximum diameter of the spherical hollow portion 13.

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.

In the stopper 1 according to the embodiment, the elastic body 21 made of an O-ring member is used.
Can be selected from commercially available O-rings. Since such an O-ring is excellent in durability, abrasion resistance, etc., the string member 31 is connected to the elastic body 21 for adjusting the length.
