Are configured to be rotatably rotatable.

The rotary hinge device 4 of this embodiment does not have a structure in which the shaft portion and the fitted portion are simply engaged, but is provided with a rotary position holding mechanism 13 by a cam engagement for holding a state of being rotated by a predetermined angle. It has a configuration provided.

Specifically, for example, the engagement biasing spring is provided in the main body case portion 7 which becomes the other rotation stopper fixing portion 7 which is inserted and connected in the rotation preventing state into the mounting hole portion 8 of the first member 1. 15
The cam engaging portion 16 is provided in a non-rotational state so as to be slidably movable, and is fixed to the attachment hole portion 8 of the base body 3 in the one non-rotational fixing portion 6 on the opposite side. A cam portion 17 which is opposed to the cam engaging portion 16 and engages with the cam (concave / concave engagement) is integrally provided, and a rotation guide shaft 18 provided in the rotation stopper fixing portion 6 penetrates each of the portions 17, 16 and 15. , The main body case portion 7 is penetrated, and the main body case portion 7 is locked by retaining and integrated.

Therefore, the rotary hinge device 4 of this embodiment is
It is configured as a tubular body, and has a detent fixing portion 6 that is inserted and connected to the mounting hole portion 8 of the base body 3 on one end side, and a detent fixing portion 7 that is connected to the first member 1 on the opposite side. With this configuration, the cam engagement portion is urged by the engagement urging spring 15.
The 16 and the cam portion 17 are configured to rotate relative to each other with the rotation guide shaft 18 as a guide so as to be cam-engaged (concave-shaped engagement). Therefore, when the second member 2 is rotated with respect to the first member 1, the base member 3 together with the second member 2 and the cam portion 17 together with the detent fixing portion 6 on one side are fixed to the main body case portion 7 (the detent fixing on the other side).

16 will rotate while sliding.

Therefore, since the cam engaging portion 16 is urged by the engagement urging spring 15, the rotational positions in which the cam engaging portions 16 engage with each other (concave and convex) are urged and held (locked). ) It will be. That is, until the concavo-convex engagement is lifted up and disengaged from this position, the rotational biasing force is generated by the engaging depression force and the engaging bias. Therefore, if the cams are engaged with each other at a position rotated by 180 degrees and one of the cam engagement positions is set at a position rotated by a predetermined opening angle, the cam engagement lock is performed at the predetermined opening angle position. Further, if the cam engagement is performed in the closed state where the first member 1 and the second member 2 are overlapped, the locked state is achieved even in the closed position, but in the closed state, the cam is in the middle of engagement (unevenness). If the position is set to the position where the engagement falls, it can be designed such that the closing biasing force is generated by the engagement dropping force and the engaging bias in the closed state.

Further, the rotation and rotation hinge device 5 of this embodiment.

The base end portion of this rotation shaft 20 is opposed to the cam portion 21 and is cam engaged. A cam engaging portion 22 that engages (concave and convex) is provided, and a cam engaging biasing spring 23 that biases the cam engaging portion 22 is provided.

Therefore, when the second member 2 is rotated about the base body 3, the cam engaging portion 22 is rotated together with the rotation rotating shaft 20 with respect to the cam portion 21 fixed to the base body 3 to prevent rotation.
Rotates.

Since the cam engagement portion 22 is urged by the cam engagement urging spring 23, the rotational position for cam engagement is urged and held (locked). That is, until the concavo-convex engagement is lifted up and disengaged from this position, the rotational biasing force is generated by the engaging depression force and the engaging bias.

Further, in the present embodiment, the rotation stopper mechanism 14 for preventing the rotation of the rotor by a predetermined angle or more is provided. Specifically, the stopper portion 24 is integrally formed on the cam portion 21 formed by metal forming, and the stopper portion 24 is
In addition, a stopper locking portion 25 that is locked by hitting by this rotation is integrally formed on the outer circumference of the metal-made cam engaging portion 22, and the stopper locking portion 25 is attached to the stopper portion 24.
