Japanese Patent No. 3114868 (see claims, detailed description of the invention {Embodiments of the invention}, paragraphs {0011} to {0016}, and FIGS. 1, 3, and 4)

  However, in the prior art shown in Patent Document 1, the outer shell has a hole and a hollow portion, and the inner wall surface of the hollow portion is a spherical continuous body. An elastic body having an O-ring shaped member is housed inside the hollow portion of the outer shell, and the elastic body passes through the hole of the outer shell so that the outer periphery of the elastic body is pressed against the inner wall surface of the hollow portion. This is a stopper that is introduced into the outer shell, and it is difficult for the stopper to be hooked in attaching or detaching a string member such as a chain when detaching or attaching the string member. The present invention overcomes this and provides a stop that can be reliably and easily implemented.

A first device of the present invention for solving the above-mentioned problems is a stopper as described in claim 1, and is as follows.
A stopper in which an elastic body is built in a hollow outer shell, wherein the hollow outer shell has a hole that communicates from outside to inside and further to the outside, and this hole is a hole through which a string member such as an elastic body and a chain can pass. Two holes are drilled, the inner wall surface of the hollow portion of the outer shell is a spherical continuous body, the elastic body is a white O-ring, and one or two outer shells are inserted into the outer shell. The diameter of the inner wall of the outer shell is slightly smaller than the diameter of the inner wall, and one or two elastic bodies are inserted in such a way that they can move freely without touching the inner wall of the outer shell. Has a hole diameter slightly smaller than the outer diameter of the cord member.

Since the stopper according to the present invention is configured as described above, the following effects can be obtained.
(1) It is possible to provide a stopper in which a string member such as a chain can be securely and easily anchored to a jewelry or other decorative item in an accessory.
(2) A string member such as a chain is caught between the outer shell and the white O-ring by having an outer diameter that moves in a free state so that the white O-ring does not press against the inner wall surface of the hollow portion of the outer shell. When two white O-rings are provided, it can be more reliably and easily moored at an appropriate position.

  A stopper having a built-in elastic body in a hollow outer shell, wherein the hollow outer shell is provided with a hole that communicates from the inside to the outside, and this hole is a hole through which a string body such as an elastic body and a chain can pass. Two holes are drilled, the inner wall surface of the hollow portion of the outer shell is a spherical continuous body, the elastic body is a white O-ring, and one or two outer shells are inserted into the outer shell. The diameter of the inner wall of the outer shell is slightly smaller than the diameter of the inner wall, and one or two elastic bodies are inserted in such a way that they can move freely without touching the inner wall of the outer shell. Stopper used for accessories having a hole diameter slightly smaller than the outer diameter of the cord body.

FIG. 1 is a sectional view showing a relationship between a stopper and a string member according to a first embodiment of the present invention.
Here, the stopper of the present invention will be described in detail with reference to FIG.
As shown in the drawing, the stopper 1 includes an outer shell 2 as a main body and an elastic body 3. The outer shell 2 has a hollow portion 6 in which a first hole 4 and a second hole 5 for passing a string member 7 such as a chain are formed and a solid is hollowed out.
The first hole 4 and the second hole 5 communicate from the outside of the outer shell 2 to the hollow portion 6. The outer shell 2 is formed by using various materials such as metal, alloy, ceramic, and synthetic resin, and can adopt various arbitrary shapes such as a sphere, a polygon, and the like. Decorative decorations can be applied.

The hollow portion 6 of the outer shell 2 is a continuous body whose inner surface is spherical. The elastic body 3 is provided with a through hole 8 through which the string member 7 such as a chain passes, and has an inner diameter slightly smaller than the outer diameter of the string member 7. The elastic body 3 is built in the hollow portion 6 of the outer shell 2 and has a spherical shape. It has an outer diameter slightly smaller than the inner diameter of the hollow part 6 and is shaped so as to be able to move freely within the hollow part 6 to some extent. In addition, one or two elastic bodies 3 are inserted into the hollow portion 6, and each elastic body can move freely to some extent.
Although it is best to use a white O-ring as the elastic body 3, it goes without saying that a perforated body made of an elastic body such as rubber or silicone rubber may be used.

  The inner diameter D2 of the through hole 8 of the elastic body 3 is smaller than the inner diameter D1 of the first hole 4 or the second hole 5 of the outer shell 2 and smaller than the outer diameter of the string member 7 such as a chain. It is. In order to insert the elastic body 3 into the hollow portion 6 of the outer shell 2, the elastic body 3 may be inserted so as to be crushed, or may be inserted through the through hole 8 using a wire or the like. The elastic body 3 is inserted by pulling out the wire from one of the first hole 4 and the second hole 5 and pulling out the wire into one of the second hole 5 and the first hole 4.

  As described above, the stopper 1 in the case where two elastic members 3 are inserted into the hollow portion 6 of the outer shell 2 will be described. The front end of the string member 7 such as a chain, a fiber string, or a sphere binding string is described. A wire is hung over the stopper, and the wire is inserted into the hollow portion 6 from the first hole 4 or the second hole 5 of the outer shell 2 to guide the wire so that the two elastic members 3 are substantially overlapped. When the elastic body 3 is inserted into the through hole 8 of the elastic body 3, the inner wall of the hollow part 6 is spherical even if it does not enter the through hole 8. The hole 8 moves freely within the portion 6 so that the through hole 8 communicates with the first hole 4 or the second hole 5 and enters the other hole (5) or the first hole (4). ) Through which the string member 7 can penetrate.

  At this time, the elastic body 3 is built in the hollow part 6 of the outer shell 2, and the outer diameter of the string member 7 forcibly passing through the inner diameter of the through hole 8 of the elastic body 3 and the elastic body 3 By appropriately selecting the inner diameter of the through-hole portion 3, frictional resistance is generated in the string member 7 passing through the through-hole portion 8 by utilizing the elasticity of the elastic body 3, and the string member 7 can be arbitrarily selected. It can be moored by shifting to the length position.

  Further, since the two elastic members 3 are built in, the holding force can be increased by increasing the portion for holding the string member 7, and the inner wall surface of the hollow portion 6 of the outer shell 2 is formed by the two elastic members 3. Since the elastic body 3 has a diameter slightly smaller than the inner diameter of the inner wall surface in the spherical shape, the elastic body 3 moves freely, and the string member 7 is caught between the elastic body 3 and the outer shell 2. There is no end.

  It can be used as a stopper for mooring various jewelry and other ornaments to appropriate positions on various chains and fiber strings used for accessories.

FIG. 4 is a cross-sectional view illustrating a relationship between the stopper and the string member according to the embodiment of the present invention.
