[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a rubber-constrained rotary connector provided to be able to be attached to and detached from both ends of accessories such as necklaces and cuffs.

[0002]

[Prior art]

 Various types of connecting devices have been proposed and used for freely connecting and disconnecting both ends of chains, continuous yarns, and the like in accessories such as necklaces and cuffs. Not practical. In order to satisfy this problem, many proposals have been made, such as a device having a mechanism using a permanent magnet, such as Japanese Utility Model Publication No. 7-90, and a device having a lock as a locking mechanism, as disclosed in Japanese Patent Application Laid-Open No. 9-327321. I have.

[0003]

[Problems to be solved by the invention]

 Although the two types mentioned above are satisfactory in that they can be easily detached and have a low risk of falling off, the former mechanism using permanent magnets has the effect of magnetic force on the human body and adverse effects on the belongings of the user. In the latter case, when the connection is broken, it is time-consuming and troublesome to remove this metal fitting first.

[0004] The present invention has been made in view of such a situation, and has a problem that there is no problem of a magnetic force and the like, and a troublesome detachment fitting of a stopper is provided even though the coupling body has a coupling mechanism that can be easily engaged and disengaged. It is an object of the present invention to provide a connecting tool which does not require a connector, has a low risk of falling off, and has a low manufacturing cost.

[0005]

[Means for Solving the Problems]

 In the present invention, a T-shaped convex side and a concave side for receiving the T-shaped side are provided with a ring for connecting continuous yarns at each outer end thereof, and each of the side is screwed about 90 degrees. Thus, the rotary connecting tool is configured such that the T-shaped tip and the inner surface of the slit are connected to each other in a direction intersecting with the direction in which the left and right pulling external force is applied by the continuous yarn.

[0006] However, the rotary connection tool has a risk of falling off due to loosening and the like, while being easy to connect. Therefore, in order to prevent this loosening, usually a method of restraining by incorporating a spring or a method of attaching an appropriate stopper mechanism is adopted, but the structure is complicated, it takes time and effort to manufacture, and the cost is expensive. . In the present invention, a method was adopted in which a rubber ring was attached between the joints and restrained by tension generated by the crushing of the rubber. As a result, a necessary and sufficient restraining force is obtained, and the structure is extremely simple, and it is easy to manufacture, and a low-cost connecting tool can be obtained.

[0007]

[Action]

 In the connecting device of the present invention having the above configuration, the T-shaped convex hooks and the concave slits for receiving the hooks can be connected by twisting by rotation to connect the continuous yarn on the loop. However, at the time of separation, the connection can be broken by rotating and twisting in the opposite direction to the above, and the individual members can be separated by separating them.

【Example】

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

In the connecting device shown in FIGS. 1 to 6, the connecting device is made of a noble metal material, and has a T-shaped protrusion 4 and a concave portion having a slit 5 for receiving the T-shaped protrusion 4. It is constituted by a pair of metal fittings of the side lock specific 2. As shown in FIG. 1, the convex-side retaining member 1 is buried with a suitably adjusted thick silicon rubber 3 and has a structure as shown in FIG. The silicone rubber 3 is sandwiched between the convex side retaining portion 1 and the concave side retaining portion 2, and is arranged and has a wall thickness such that it is slightly crushed. As shown in FIG. 3, the concave-side fastener 2 has a slit 5 in which the elliptical shape and the circle are fused at the coupling portion, receives the T-shaped projection 4 of the convex-side fastener 1, and as shown in FIG. The inner back side is shaved so that it can be rotated half a turn while pressing 1. At the end point of rotation, the purpose is to have an appropriate click feeling in the rotation operation, and to provide a locking effect in conjunction with the restoring force generated by the collapse of the built-in silicon rubber 3 on the convex side retaining concrete 1. Groove processing is performed on the back side of the inner surface.

In this example, the silicone rubber 3 is attached to the convex-side retaining member 1. However, the concave-side retaining member 2 may be used as long as the shape and function are not adversely affected, and each retaining member has a truncated cone shape in appearance. However, it has no particular purpose and can be freely designed. Further, the projection and the slit 5 to be combined are not specified as T-shaped, and may be freely designed. Since the silicone rubber 3 is structurally exposed, the transparent type material is used in this example, considering that it is a decorative product. However, it is interesting to use a colored material such as black or a decorative product. .

FIG. 5 and FIG. 6 are opposite views, and are explanatory views of the mechanism process of the present invention. In FIG. 5 and FIG. 6, the positions of the T-shaped protrusions 4 and the slits 5 of the convex-side retaining member 1 and the concave-side retaining member 2 are relatively adjusted so as to engage with each other, and while the silicone rubber 3 is appropriately crushed, The T-shaped projections 4 of the convex retaining member 1 are connected to the groove portion formed on the inner surface rear side of the concave retaining member 2 by being rotated by a half turn so as to be pulled by the restoring force of the silicone rubber 3. The dimensional structure is such that an appropriate amount of the restoring force of the silicone rubber 3 remains even in this final connection state. This connection is shown in the cross-sectional view of FIG.

[00012]

[Effect of the invention]

 According to the present invention, despite the coupling body having a coupling mechanism that can be easily removed, there is no problem such as magnetic force, and it is not necessary to remove the troublesome stopper fitting, there is little danger of falling off, and the connection cost is low. Tool. The structure is such that the T-shaped fitting is not pushed into the groove by the restoring force of the silicone rubber 3 and is not loosened. In some cases, the fittings can be easily released by half-turning the clamps while pressing them together.

Normally, such a mechanism using a spring or a spring is industrially common, but it is dimensionally large, difficult to fine-tune, and structurally complicated. Manufacturing costs also increase. Especially for decorative parts, when the dimensions are large, there is a problem in the product design and it becomes difficult to handle. In the present invention, these problems have been solved by replacing the role of the spring or spring with silicone rubber.
