These notches 84 and 86 correspond to the protrusions 78 and 80 of the spring plate 64 and are engaged when the respective positions coincide with each other. In the section where these positions do not coincide with each other, the protrusions 78 and 80 become the cam plate. The lower surface of 66 is brought into contact with and an appropriate friction torque is generated.

  As shown in FIG. 4, the lower end portion of the rotating shaft 6 is inserted into the fixing hole 88 of the support frame portion 12 and fixed. Further, with respect to the open / close shaft portions 14 and 16 installed in a direction orthogonal to the rotary shaft 6, the open / close shaft portion 14 is formed with a shaft portion 92 that is rotatably supported in the bearing hole 90 of the bearing portion 8. The shaft 92 is passed through and supported by the bearing hole 90, and a stopper 94 is attached to the tip of the shaft portion 92. Further, the opening / closing shaft portion 16 is formed with a shaft portion 93 that is rotatably supported in the bearing hole 91 of the bearing portion 10. The shaft portion 93 is supported by passing through the bearing hole 91, and the distal end portion of the shaft portion 93. A stopper 95 is attached to the.

  Further, the opening / closing shaft portion 16 is formed with a slide shaft portion 96 formed narrower than the opening / closing shaft portion 14 and a large diameter portion 98, and a flat surface portion 100 is formed by cutting a part of the slide shaft portion 96 or the like.

A slide hole 110 having a shape similar to the cross-sectional shape of the slide shaft portion 96 is formed in the slide cam 106, and a protrusion 112 and a recess 114 are formed on a surface portion facing the fixed cam 108. Further, the fixed cam 108 is formed with a fixed protrusion 118 that is inserted and fixed in the fixed groove 116 of the bearing portion 10, and a circular hole 120 for rotating the slide shaft portion 96 is formed. A projecting portion 112 and a recessed portion 124 that mesh with the projecting portion 112 and the recessed portion 114 of the slide cam 106 are formed on the surface portion facing the cam 106.

  Thus, the opening / closing shaft 4 composed of the opening / closing shaft portions 14 and 16 is supported by the bearing portions 8 and 10 and can be rotated. For this reason, the slide cam 106 and the coil spring 104 rotate together with the slide shaft portion 96 of the opening / closing shaft 4. Is possible. On the other hand, the fixed cam 108 is fixed to the bearing portion 10 and does not rotate.

  The operation of the hinge device 2 will be described. In the hinge device 2, a first rotation with the opening / closing shaft 4 as the rotation center and a second rotation with the rotation shaft 6 as the rotation center are realized as two orthogonal rotations.

  In the first rotation, as shown in FIG. 5A, when the opening / closing shaft 4 is rotated in the NX direction, the slide cam 106 and the fixed cam 108 are protruded from each other with the protrusion 112 and the recess 120, and the recess 114 and the protrusion 122. In this case, the slide cam 106 moves in the X1 direction by the restoring force of the coil spring 104, and the slide cam 106 is in close contact with the fixed cam 108. When the opening / closing shaft is rotated in the NX direction from this position, as shown in FIG. 5B, the slide cam 106 and the fixed cam 108 are aligned with the protrusion 112 and the protrusion 122, and the recess 114 and the recess 120, respectively. In this case, the slide cam 106 moves in the direction of the arrow X2, and the coil spring 104 is compressed by the rising amount of the protrusions 112 and 122. That is, the restoring force due to the compression of the coil spring 104 acts between the slide cam 106 and the fixed cam 108, and becomes a force for preventing the opening / closing shaft 4 from rotating. The user can experience a feeling of torque with respect to the rotation of the opening / closing shaft 4.

  Then, depending on whether the opening / closing shaft 4 is moved in the direction opposite to the NX direction or the NX direction is further advanced, the slide cam 106 and the fixed cam 108 have the protrusion 112 and the protrusion 122, and the recess 114 and the recess 120, respectively. And shifts to a state shown in FIG. 5C. At this time, since the compression state of the coil spring 104 is reduced, the user can feel a sense of torque released with respect to the rotation of the opening and closing shaft 4.

  In the second rotation, as shown in FIGS. 6A and 6B, when the rotating shaft 6 is rotated in the NY1 direction, the side of the stopper claw 51 of the stopper ring 50 abuts against the stopper portion 48 and rotates. Further, when the rotating shaft 6 is rotated in the NY2 direction from the position, the side of the stopper claw 51 of the stopper ring 50 abuts against the stopper portion 48 to prevent the rotation. That is, it can be rotated left and right in the angle section until the stopper claw 51 hits the stopper portion 48.

  In that case, at the portion where the protrusions 78 and 80 of the spring plate 64 abut against the lower surface portion of the cam plate 66, a feeling of torque due to friction between the two is obtained, and the protrusions 78 and 80 are notched 84, When it is fitted into the shaft 86 (FIG. 1), a feeling of torque released from the rotation prevention by the friction is obtained. From such a sense of torque and a feeling of rotation prevention due to friction, the rotational position and its stop position can be experienced.

  As described above, the hinge device 2 has a structure in which the L-shaped projecting pieces 22 and 24 are combined to form the shaft frame portion 18, and the processing cost of each part can be reduced. it can. Further, the production cost of the opening / closing shaft 4 can be reduced, for example, the parts constituting the shaft frame portion 18 can be manufactured by sheet metal processing.

  The shaft frame portion 18 is a structure in which the bearing plates 26 and 28 that support the rotating shaft 6 are combined with the projecting pieces 22 and 24, and has a mechanical strength equivalent to that of the opening and closing shaft portions 14 and 16. Configured as a body.

  Further, even if the specification of the hinge device 2 varies, the length of the rotary shaft 6 and the opening / closing shaft 4 is adjusted without changing the shaft frame portion 18 by the L-shaped projecting pieces 22 and 24. Thus, an equivalent hinge device 2 having a different size and length can be realized. Even when the specification is changed, the manufacturing cost of the hinge device 2 can be reduced by sharing the parts.
