  As shown in FIG. 19, when the hinge device 1 is attached to a folding mobile phone, the fixing plate 31 of the folding hinge portion 4 of the hinge device 1 is attached to the back case 132 of the main body portion 13 of the mobile phone. The hinge device 1 is supported by fixing to the three holes 80 using screws or the like, and the front case 134 is attached using screws or the like. The lid 12 of the mobile phone sandwiches the opening and closing hinges 2 and 3 between the outer case 136 and the inner case 138, and fixes them using screws or the like.

  Here, the basic operation of the hinge device 1 will be described. In the state where the cover 12 of the mobile phone is closed, the sphere 22 of the hole 57 of the first spacer 23 in the opening and closing hinges 2 and 3 is the first concave surface of the outer guide path 44 of the first disk 21. While engaging with the portion 46, the sphere 22 of the other hole portion 56 is engaged with the first concave surface portion 49 of the inner guide path 45. When the lid 12 is closed, the sphere 22 held by the first spacer 23 is formed to stop on the inclined surface in front of the center of the first concave portion 46 of the first disk 21. Thus, the urging force for closing the lid portion 12 is maintained so that the lid portion 12 does not rattle at the closed position.

  Further, in the bent hinge portion 4, since the large-diameter portion 77 of the cam member 27 is engaged with the locking body 36 at the position where the lid body portion 12 is closed, the locking body 36 is pushed downward. The 36 long legs 98 are plunged into the locking holes 79 of the fixing plate 31. For this reason, the second spacer 34 and the base body 15 are prevented from rotating, and the lid 12 is not bent in the left-right direction. At this time, the four spheres 33 provided on the second spacer 34 are respectively engaged with the concave surface portions 86 of the second disk 32.

  Further, the fixed cylinder 38 is always fixed, and the base body 15 rotates with this as a rotation axis. The second stopper 40 rotates integrally with the base 15, and at this time, the engaging convex portion 114 of the first stopper 39 rotates while engaging with the locking convex portion 119 of the second stopper 40, and further the first stopper 39. The engaging convex portion 114 of the stopper 39 engages with the protruding portion 108 of the fixed cylinder 38 and restricts the rotation of the base body 15.

  At the reference position in which the lid 12 is in the same direction as the main body 13, the locking projection 119 of the second stopper 40 is positioned above the protrusion 108 of the fixed cylinder 38. The counterclockwise rotation of the base body 15 (the lid body portion 12) causes the second stopper 40 to rotate integrally therewith to rotate the first stopper 39 in a free state. The rotation of the base 15 stops at a position where 114 engages with the protruding portion 108 of the fixed cylinder 38, that is, a position where the base 15 rotates 180 degrees counterclockwise.

  From this state, the base 15 is returned to the original reference position by rotating 180 ° clockwise. Further, when the base body 15 is rotated clockwise, the engaging convex portion 119 of the second stopper 40 is engaged with the engaging convex portion 114 of the first stopper 39 from the opposite side and is rotated. The rotation of the base 15 stops at a position where the portion 114 engages with the protruding portion 108 of the fixed cylinder 38, that is, a position where the base 15 rotates 180 ° clockwise. Accordingly, the base body 15 is rotated in the range of 180 ° to the left and right, and the first stopper 39 is rotated 90 ° to the left and right.

  Next, the opening / closing operation | movement of the cover part 12 of the mobile telephone using the said hinge apparatus is demonstrated. When the lid 12 is opened, the positions where the deployment of the lid 12 is fixed include a first deployment position and a second deployment position. As shown in FIG. 20, the first deployed position is a position where the opening angle is smaller than 180 ° (approximately 160 °), and the mobile phone can be operated at this position. Further, when the lid 12 is opened at about 180 °, the second deployment position shown in FIG. 19 is reached, where the deployment of the lid 12 is fixed, and this is stopped by a predetermined stop mechanism for the lid 12. The above development is not possible. At the second deployed position, the lid 12 can be bent left and right.

  In the cellular phone equipped with the hinge device, when the lid 12 is opened by hand, the opening and closing hinges 2 and 3 are operated. At this time, the first spacer 23 rotates together with the cam member 27 and the case 25, and each sphere 22 held by the first spacer 23 is engaged with the first concave portions 46 and 49 of the first disk 21. Get out. As the first spacer 23 rotates, each sphere 22 rolls on the guide paths 44 and 45 of the first disk 21 and moves in the direction of the second concave portions 47 and 50. Eventually, when the lid portion 12 reaches the first deployed position, the spheres 22 engage with the second concave surface portions 47 and 50 together with the click feeling, and are fixed at this position by the urging force of the coil spring 24. Is done.

  In addition, since the large-diameter portion 77 of the cam member 27 is engaged with the locking body 36 from the position where the lid 12 is closed to the first deployed position, the locking body 36 is pushed downward. The long leg portion 98 of the locking body 36 is plunged and locked into the locking hole 79 of the fixing plate 31. For this reason, the rotation of the second spacer 34 and the base body 15 is prevented, and the operation is stopped, and the lid portion 12 does not rotate in the bending direction.

  The operator usually operates and uses the cellular phone at the first deployed position. In the first unfolded position, the lid 12 is in a normal vertical state, and character information and the like are displayed in horizontal writing on the vertically long display screen 14 of the lid 12.

  Further, when the operator opens the lid 12, the spheres 22 of the first spacer 23 come out of the second concave portions 47 and 50 of the first disk 21, and the lid 12 is expanded in the second manner. When it reaches the position, it engages with the third recesses 48 and 51 and is fixed at this position together with the click feeling. At the same time, when the lid portion 12 reaches the second deployed position from the first deployed position, the large diameter portion 77 of the cam member 27 associated with the locking body 36 is switched to the small diameter portion 76. For this reason, the latching body 36 is pushed upward by the coil spring 37, and the long leg 98 of the latching body 36 is pulled out from the latching hole 79 of the fixing plate 31 to be unlocked, and the second spacer 34 and The rotation of the base body 15 is released from the operation stop state and becomes free.

  In this second deployed position, the hinge mechanism of the hinge device 1 switches from the open / close hinge portions 2 and 3 to the function of the folding hinge portion 4. When the operator bends the lid portion 12 counterclockwise, for example, from the bending reference position, the four spheres 33 provided on the second spacer 34 come out of the concave surface portion 86 of the second disk 32, respectively. Then, it rolls on the guide path 84 and moves.

  At this time, the distal end portion of the long leg portion 98 of the locking body 36 comes into contact with and slides on the surface of the fixing plate 31. For example, if the lid body portion 12 is operated in the closing direction, The abutting cam member 27 tries to move from the small-diameter portion 76 to the large-diameter portion 77, but the locking member 36 cannot move downward by the fixing plate 31, so the cam member does not turn and the closing direction operation of the lid 12 is prevented. Is done. Eventually, as shown in FIG. 21, when the lid 12 reaches the first bent position inclined by 90 °, the four spheres 33 engage with the other concave surfaces 86 together with the click feeling, and the coil spring It is fixed at this position by the urging force of 35.

  The operator can operate and use the mobile phone at the first bent position. At the first bent position, the lid portion 12 is in a sideways state, and the display screen 14 of the lid portion 12 is horizontally long when viewed from the operator. Therefore, in this state, it is possible to display characters or figures on the display screen 14 which is horizontally long for a long time. In particular, when a large amount of character information or the like is displayed, the horizontally long display form is easy for the operator to read. Also, when displaying character information or the like input by the operator, it can be displayed horizontally long, so that it is easy to read.

  Further, when the operator turns the lid body portion 12 counterclockwise, the engaging convex portion 119 of the second stopper 40 that rotates with the rotation of the base body 15 is engaged with the engaging convex portion 114 of the first stopper 39. Eventually, the engaging projection 114 of the first stopper 39 engages with the protruding portion 108 of the fixed cylinder 38 at the second bending position where the lid 12 is rotated 180 ° from the bending reference position. Therefore, the rotation stops and it cannot be bent at an angle larger than this. At the same time, when the second bent position is reached, the sphere 33 engages with each other concave surface portion 86 with a click feeling, and the lid portion 12 is fixed at this position by the urging force of the coil spring 35.

  In the second folding position, the lid body portion 12 rotated by 180 ° overlaps the main body portion 13, and the mobile phone is apparently folded in two. In this state, the display screen 14 of the lid 12 is face up and the mobile phone can be easily held and managed. Therefore, when waiting for some kind of incoming call, the incoming call information displayed on the display screen 14 can be immediately confirmed as it is, with the mobile phone kept compact, and is functional. Even in the second bent position, it is easy to see if characters or the like are displayed horizontally in the long side direction of the display screen 14 of the lid 12.

  When the folded lid body 12 is returned to the original position, an operation opposite to the above-described bending operation may be performed, and the operation of the cam mechanism of the second spacer 34 and the second disk 32 is also substantially bent. And no different. This time, the lid 12 is turned in the reverse direction, and the lid 12 is fixed again at a position rotated 90 °. Therefore, the mobile phone may be operated here. When the lid body portion 12 is further turned, the lid body portion 12 returns to the second deployed position before being bent.

  If the lid 12 is tilted forward from the second deployed position, the lid 12 returns to the first deployed position and is fixed here. At this time, the character information on the display screen 14 of the lid 12 is returned to the original short display along the short side of the display screen 14. If the lid 12 is closed as it is, the lid 12 is closed with a click feeling.

  Therefore, according to the mobile phone using the hinge device 1 according to the above embodiment, in addition to the unfolding operation before and after the lid body portion, the lid body portion can be bent in a 90 ° direction orthogonal to the main body portion. It is possible to display a vertically long display screen horizontally as viewed from the operator, and to display a long display in a direction along the long side of the screen so that display characters can be easily seen. effective. In addition, since the lid can be folded at 180 °, the lid overlaps with the main body to make it compact and easy to maintain and manage the mobile phone. Information can be confirmed and the functionality is excellent.
