The inner cam portion 21d showing an arc on a concentric circle protruding from the rotating cam portion 21a and the fixed cam portion 23a of the rotating cam member 21 and the fixed cam member 23 respectively on the inner circumferential side and the outer circumferential side thereof. And 23c and outer cam portions 21e and 23d are provided with different positions, respectively, when the rotary cam member 21 rotates, but when the support member 11 rotates, that is, when the second frame 3 When the inner and outer cam portions 21d and 23c and the outer cam portions 21e and 23d come into contact with each other during opening and closing, a strong precushion torque is generated. Incidentally, the inclined portions 21f to 21i and the inclined portions 23e to 23h are provided at both ends of the inner cam portions 21d, 23c, and the outer cam portions 21e, 23d, respectively.

Next, the operation in the case where two hinge devices A according to the present invention are used as the opening and closing device of the notebook 1 will be described.

In a normal state in which the notebook 1 is not used, the first frame 2 and the second frame 3 are in a state of being immersed in a polymerization state (0 °). At this time, as shown in Fig. 7 to Fig. 10, the bottom plate 6a and the mounting plate 6i of the mounting member 6 are attached to the mounting portion 2c provided on the rear upper surface of the first frame 2. It is attached using mounting screws 16a and 16b, and its upper part is covered by the cover 2b. Further, a second frame 3 is attached to the support member 11 by using mounting holes 11i, 11i, 11i and the support piece 11b provided in the first support substrate 11a. As shown in Fig. 7, when the first frame 2 and the second frame 3 are in the closed state, the cam portion 7a of the cam slider 7 and the cam recess 10a of the hop-up cam member 10 are closed. Since it is in a press-contacting state and the hop-up cam member 10 is pressed in the clockwise direction, the rotation torque is transmitted to the support member 11 using the rotation transmission member 12, and the support member 11 is used to make the rotational torque. Since the frame 3 of 2 is pressed against the side of the first frame 2, the frame 3 is held in a state where the first frame 2 and the second frame 3 overlap with each other. In this confined state, as shown in Fig. 11A, each of the outer cam portions 21e and 23d and the inner cam portions 21d and 23c of the rotary cam portion 21a and the fixed cam portion 23a is shown. Each of the inclined portions 21h, 23g, 21h, and 23f is in press contact with each other, and there is a slight gap between the outer cam portions 21e and 23d and the inner cam portions 21d and 23c. There is a gap.

In this way, the locked state of the first frame 2 and the second frame 3 is maintained, so that the locking mechanism for locking the first frame 2 and the second frame 3 to the closed state can be unnecessary.

In the case of using the notebook 1, when the second frame 3 is manually opened with respect to the first frame 2, the closing force of the first and the above-described hop-up mechanism 5 is applied and the rotation cam portion 21a of the precushion mechanism 20 is used. ) And the resistance due to the pressure contact action of the outer cam portions 21e and 23d of the fixed cam portion 23a, but when the opening angle exceeds about 15º, the rotation cam of the precushion mechanism 20 as shown in Fig. 11B. The contact state is relaxed between the outer cam portion 21e of the rotating cam portion 21a of the member 21 and the outer cam portion 23d of the fixed cam portion 23a of the fixed cam member 23, and each of the outer cam portions 21e. , The contact state between the 23d and the inner cam portions 21d and 23c becomes weak, and as shown in FIG. 8, the cam portion 10a of the hop-up cam member 10 is the cam portion of the cam slider 7. 7b) abuts against the side, the hop-up cam member 10 exerts a force that rotates in a counterclockwise direction, and this rotation torque is supported by the rotation transmission member 12. Since it is transmitted to the supporting member 11, the second frame 3 mounted on the supporting member 11 automatically hops up, and as shown in Fig. 9, the second frame 3 opens up to a predetermined example, such as 60 ° (also referred to as a hop up angle). do.

When the second frame 3 is opened with respect to the first frame 2 up to this hop-up angle, as shown in FIG. 9, the pressing force against the hop-up cam member 10 by the cam slider 7 is stopped and the precushion mechanism ( The rotating cam member 21 of the 20 and the rotating cam portion 21a of the fixed cam member 23 and the outer cam portion 21e and the outer cam portion 23d of the fixed cam portion 23a are brought into a press contact state, and then FIG. 11. As shown in (c), the rotary cam member 21 of the precushion mechanism 20, the rotary cam portion 21a of the fixed cam member 23, and the outer cam portions 21e, 23d of the fixed cam portion 23a. ) And the inner cam portions 21d and 23c maintain the pressure contact state, and the precushion washer 22 is formed of the first support substrate portion 11a and the second support substrate portion 11c of the support member 11. The second frame 3 can be stopped freely with respect to the first frame 2 freely in the range of its use angle from the tighter press contact therebetween. This state is shown in FIG.

Accordingly, the notebook 1 can be used in a stable holding state by stopping the second frame 3 at any angle that can be stopped freely with respect to the first frame 2.

After using the notebook 1, when the second frame 3 is closed with respect to the first frame 2, the first frame is first closed due to the resistance of the precushion torque of the precushion mechanism 20, and then the precushion mechanism ( The rotating cam member 21 of the 20 and the rotating cam portion 21a of the fixed cam member 23 and the outer cam portions 21e, 23d, 21d, and 23c of the fixed cam portion 23a are press-contacted. In the release from the state, it is closed against the relatively weak pretorque and the elastic resistance of the hop-up mechanism 5, and the hop-up mechanism 5 rotates the hop-up cam member 10 in the closing direction from a holding angle of about 15º. By applying a force, this rotation torque is transmitted to the support member 11 using the rotation transmission member 12, so that the second frame 3 is automatically closed. However, at this time, the inclined portions 21f of the rotary cam portion 21a and the outer cam portions 21e and 23d of the fixed cam portion 23a and the inclined portions 21h and 23g of the inner cam portions 21d and 23c. , 23f is press-contacted, and the auto-up torque for the second frame 3 is buffered by the hop-up mechanism 5, so that the second frame 3 makes a sound with respect to the first frame 2. It is not closed. In addition, since the elastic means 8 uses compression coil springs 8a and 8b having different diameters, the operation by the hop-up mechanism 5 can be made to feel soft.

[Example 2]

Fig. 14 shows another embodiment of the hinge device according to the present invention, and the hinge device B according to the second embodiment is the same as the hinge device A of the first embodiment except for the cam slider in terms of its constituent members. Therefore, the same members as those of the hinge device A of the first embodiment are denoted by the same reference numerals except for the hop-up cam member. Cam slider 32 of hinge device B of the second embodiment The cam slider 7 of the first embodiment differs in width from that of the government. The width of the step 32a of the cam slider 32 of the second embodiment is wider than the width n of the cam slider 7 of the first embodiment and has a relationship of n <n.

 Therefore, when the hinge device A of the first embodiment and the hinge device B of the second embodiment are used as the opening and closing device of the notebook 1, when the first frame 2 of the second frame 3 is opened, the hinge device A is first opened. The cam tip 10a of the hop-up cam member 10 is separated from the top 7a of the cam slider 7, and then the cam tip 31a of the hop-up cam member 31 of the hop-up mechanism 30 of the hinge device B. ) Falls from the front end 32a of the cam slider 32. For this reason, the hop-up operation to the second frame 3 by the hop-up mechanisms 5 and 30 of the hinge device A and the hinge device B is abrupt compared to that of the pair of the hinge devices A and A simultaneously. In addition, since it becomes soft, the operability at the opening and closing operation of the second frame 3 and the first frame 2 is improved.

Next, as another embodiment of changing the start time of the hop-up operation of the hinge device A and the hinge device B, the hop-up cam members 10 and 31 of the hinge device A and the hinge device B are mounted on the hinge shaft 9. The position of the circumferential direction may be changed. Even in this manner, the timings at which the cam recesses 10a and 31a of the hop-up cam members 10 and 31 fall from the tops 7a and 32a of the cam sliders 7 and 32 are changed. In this way, abrupt hop-up operation can be reduced, and operability can be improved.
