Furthermore, although the embodiments of the shaft bodies and bearing bodies of the present invention have been described above, they are not necessarily limited and combinations may be made freely.

The main material constituting each shaft body and bearing body mentioned above is a resin material, but in particular, industrial resin materials such as polyacetal, polycarbonate, and nylon, or industrial resin materials such as glass fiber and carbon fiber are used. A mixture of reinforcing materials may also be used.

The metal parts are made of aluminum, iron, stainless steel, titanium, zinc, etc., and are selected as a single material or a composite material depending on the required strength and processing method.

Note that it can also be used by making a composite of metal and resin so that the surface of the metal is made of resin, or by adding metal to the reinforcement of the resin material.

Effects of the Invention Since the present invention is configured as described above, it produces the following effects.

In a joint formed of a shaft body and a bearing body, spring elasticity is imparted to a part of the shaft body that is pivotally connected, and the rotation bearing is rotated with the tip of the spring elastic portion as the center of the rotation axis. By making it slide inside the body, the spring elastic part of the rotating shaft body is not bent in the direction perpendicular to the rotating shaft, but the spring elastic part of the rotating shaft body can be freely rotated by only partially inserting it into the rotating bearing body. It is possible to complete the connection.

Furthermore, additional functions such as the ability to arbitrarily control the sliding friction resistance during the coupling and return rotation can be easily added.

The structure of the present invention can be used as a removable coupling structure in place of a hinge structure for rotating parts such as furniture, containers, office machines, vehicles, aircraft, communication equipment, measuring instruments, ships, containers, etc. It can be widely used in structures and mechanical objects.

In addition, by using the coupling structure of the present invention, a rotatable coupling with a back hinge specification can be easily achieved without the need for an axle pin and without exposing the hinge part to the appearance of detachable attachment.

Furthermore, since a number of methods can be used for releasing the pivoted connection, it is possible to arbitrarily select a release method suitable for each connection situation.

In addition, compared to conventional hinges that can be attached and detached, attaching and detaching the hinge does not require the movement of the five members in the lateral direction relative to the axis provided on one hinge member. It is even easier to attach and detach from the front of the opening.

In addition, although conventional hinge hinges can be attached and detached from the direction perpendicular to the axis, the rotation trajectory is not fixed, resulting in large center runout and the connection being likely to come off during rotation, which tends to limit the application of the connection. It is of structure.

By providing the locking slope on the rotating sliding contact portion, it is possible to temporarily stop the rotation during the rotation process, or to fix or release the rotation at the rotation stop position.

In addition, during rotation, the rotation process can be controlled by generating strip torque and lock torque at the rotating sliding contact portion to provide a rotation damper function that utilizes the frictional resistance force during rotation.

Furthermore, if a wear-resistant material with low surface tension such as Teflon is installed on sliding contact parts such as the surface of the curved part of the shaft body, the interlocking piece part, and the curved wall surface of the bearing body, smoother movement can be achieved. It is possible to provide a shaft body and bearing body with good durability.
