Friction force application part 73 is it is pressed against the parts on the A cam body 71 to B cam body 72 application of forces.As friction force application part 73, be not particularly limited, for example be preferably the leaf spring 78 of ring-type etc.The number of leaf spring 78 is not particularly limited, and can be one, also can for example be preferably four for more than two.These leaf springs 78 are arranged to around the axle of hinge axis 2: contact with second of B cam body 72, this second is the face of the opposition side of the contact-making surface 72b that contacts with A cam body 71 of B cam body 72.On the hinge axis 2 of the face of the B of these leaf springs 78 cam body 72 opposition sides, promptly on the second end of hinge axis 2, be provided with packing ring 79.By to riveting, leaf spring 78 is installed on the hinge axis 2 from the second end of the outstanding hinge axis 2 of this packing ring 79.

On the contact-making surface 72b of the contact-making surface 71b of A cam body 71 and B cam body 72, for example be provided with A nose of cam 74 and B nose of cam 75, when rotational angle is in 45 °～180 ° the scope, thereby A nose of cam 74 and B nose of cam 75 make and produce above-mentioned friction form free halted state between hinge axis 2 and above-mentioned installing component 3.Described A nose of cam 74 and B nose of cam 75 form respectively that to be convex from the contact-making surface 72b of the contact-making surface 71b of A cam body 71 and B cam body 72 outstanding, when rotational angle is in 45 °～180 ° the scope, the front end face of A nose of cam 74 contacts with the mutual face of the front end face of B nose of cam 75, thereby has produced friction between hinge axis 2 and installing component 3.

As shown in figure 11, A nose of cam 74 is preferably by being the center with hinge axis 2 (through hole 71a), forming a circular-arc A nose of cam 74a and the 2nd A nose of cam 74b constitute on the contact-making surface 71b of A cam body 71.A described A nose of cam 74a and the 2nd A nose of cam 74b form different circular-arc of diameter, and front end face is plane, and highly roughly the same, and to be formed on hinge axis 2 (through hole 71a) be on the opposed locations at center.The diameter of the one A nose of cam 74a for example forms with the size less than the diameter of the 2nd A nose of cam 74b.The both ends of the circular arc direction of the both ends of the circular arc direction of the one A nose of cam 74a and the 2nd A nose of cam 74b are preferably respectively and are formed obliquely.

As shown in figure 12, B nose of cam 75 is preferably by being that the center forms a circular-arc B nose of cam 75a and the 2nd B nose of cam 75b and constitutes with hinge axis 2 (running through mating holes 72a) on the front end face of B nose of cam 75.A described B nose of cam 75a and the 2nd B nose of cam 75b form different circular-arc of diameter, and front end face is plane, and highly roughly the same, and they to be formed on hinge axis 2 (running through mating holes 72a) be on the opposed position, center.The diameter of the one B nose of cam 75a for example forms the diameter dimension of size less than the 2nd B nose of cam 75b, and is roughly the same with the diameter dimension of an A nose of cam 74a.The diameter of the 2nd B nose of cam 75b is with the size formation roughly the same with the diameter of the 2nd A nose of cam 74b.The both ends of the circular arc direction of the both ends of the circular arc direction of a described B nose of cam 75a and the 2nd B nose of cam 75b are preferably respectively and are formed obliquely.

Like this, when rotational angle is in 45 °～180 ° the scope, the front end face of the one A nose of cam 74a contacts with the front end face face of a B nose of cam 75a, and the front end face of the 2nd A nose of cam 74b contacts with the front end face face of the 2nd B nose of cam 75b, thereby constitute between hinge axis 2 and installing component 3, promptly between first housing 11 and second housing 12, produce the friction that can constitute free halted state.In addition, when rotational angle is in 0 °～45 ° the scope, the front end face of the one A nose of cam 74a and the front end face of the 2nd A nose of cam 74b and the contact-making surface 72b of B cam body 72 (except that the face a B nose of cam 75a and the 2nd B nose of cam 75b) face contacts, and the contact-making surface 71b of the front end face of a B nose of cam 75a and the 2nd B nose of cam 75b front end face and A cam body 71 (except the face an A nose of cam 74a and the 2nd A nose of cam 74b) face contacts, at this moment, constitute between hinge axis 2 and installing component 3 and do not produce the friction that can constitute free halted state.

The following describes the effect of hinge means 1 of the present invention and portable set 10.

Under the common state that portable set 10 is not used, first housing 11 and second housing 12 are in the closure state that overlaps.At this moment, as shown in Figure 5, the abutting part 55 of slide unit 52 contacts with an inclined-plane of nose of cam 54, and support component 4 is compressed spring 56 to the closing direction application of force with respect to installing component 3, so, the closure state that first housing 11 and 12 maintenances of second housing overlap.Like this, because first housing 11 and second housing 12 remain on closure state, therefore can not need to be used for a housing 11 and second housing 12 are locked as the blocking mechanism etc. of closure state.Its result is the latch-release action that needn't be used to unlock when opening first housing 11 and second housing 12.

When using this portable set 10, for example second housing 12 being applied active force, to make second housing 12 serve as that axle rotates with respect to first housing 11 with hinge axis 2.When rotational angle was 0 °～15 °, this power made second housing 12 rotate with respect to first housing 11, and the active force that makes slide unit 52 overcome compression spring 56 can move in installing component 3.As shown in Figure 6, when rotational angle is 15 ° and when surpassing 15 °, the abutting part 55 of slide unit 52 arrives another inclined-plane after slipping over leading section from an inclined-plane of nose of cam 54, so, by means of the active force of compression spring 56, it is 45 ° that second housing 12 rotates until rotational angle automatically with respect to first housing 11.

Then, as shown in Figure 7, rotational angle is reached 45 ° second housing 12 apply active force to make second housing 12 serve as the axle rotation with respect to first housing 11 with hinge axis 2.At this moment, overcome the active force of leaf spring 78, the one an A nose of cam 74a and a B nose of cam 75a bump against each other, the mutual face of front end face of the front end face of the one A nose of cam 74a and a B nose of cam 75a slides contiguously, and the 2nd A nose of cam 74b and the 2nd B nose of cam 75b bump against each other, and the mutual face of front end face of the front end face of the 2nd A nose of cam 74b and the 2nd B nose of cam 75b slides contiguously.This state carries out between 180 ° after rotational angle surpasses 45 °.

When surface contact state, when the active force by means of leaf spring 78 stops the rotation of second housing 12, because the front end face of an A nose of cam 74a contacts with the front end face face of a B nose of cam 75a, the front end face of the 2nd A nose of cam 74b contacts with the front end face face of the 2nd B nose of cam 75b, produced friction by above-mentioned two faces contact, so second housing 12 stops and remaining on this position.Like this, the keyboard of being located at upper surface of the display of second housing 12 and first housing 11 will expose, and carries out keyboard operation so can see display.Under the situation of the angle of wanting in rotational angle is 45 °～180 ° scope, to regulate display (second housing 12), second housing 12 is rotated so that it is when stopping on the desired position with respect to first housing 11, display will stop and remaining on this position, so, can be easily be desired angle with the angular adjustment of display.

After the use, when turning back to closure state, second housing 12 is rotated to closing direction with respect to first housing 11.At this moment, the mutual face of front end face of the front end face of the one A nose of cam 74a and a B nose of cam 75a slides contiguously, and the 2nd A nose of cam 74b and the mutual face of the 2nd B nose of cam 75b slide contiguously, when rotational angle reaches 45 °, an A nose of cam 74a and a B nose of cam 75a engage and the 2nd A nose of cam 74b is disengaged with the 2nd engaging respectively of B nose of cam 75b.When rotational angle was in 45 °～15 °, the active force that overcomes compression spring 56 made 12 rotations of second housing.When rotational angle during less than 15 °, the abutting part 55 of slide unit 52 arrives an aforesaid inclined-plane after slipping over leading section from another inclined-plane of nose of cam 54, so, active force by means of compression spring 56, second housing 12 rotates to rotational angle automatically with respect to first housing 11, and to be 0 ° be closure state, and first housing 11 and second housing 12 remain on the closure state that overlaps.

Therefore, hinge means 1 of the present invention and portable set 10 are when carrying out on-off action, have first housing 11 zones of rotation automatically, and when opening, do not need the latch-release action that is used to unlock, so can carry out on-off action with good operability.

In addition, the sucker mechanism 5 and the mechanism 6 of upspringing, especially upspring mechanism 6 by having the slide unit 52 that moves back and forth along rectilinear direction and as compression spring 56 to the force application part 53 of these slide unit 52 application of forces, make that the application of force direction of slide unit 52 is a rectilinear direction, so, even second housing 12 that notebook computer is heavier so also can make the rotation automatically fully of second housing 12 by the mechanism 6 of upspringing.In addition, owing to use formation sucker mechanism 5, upspring mechanism 6 and friction mechanisms 7 such as cam body 51, slide unit 52, compression spring 56, A cam body 71, B cam body 72 and leaf spring 78, so simple in structure, used unit quantity is few, can reduces cost and realize miniaturization.

As mentioned above, hinge means of the present invention and portable set are when opening first housing and second housing, has support component by the mechanism zone of rotation automatically of upspringing, and when closed first housing and second housing, has the zone that support component rotates automatically by sucker mechanism, and first housing and second housing are remained closure state by sucker mechanism, so can carry out opening and closing operations, therefore be specially adapted to notebook computer with good operability.
