Abstract
To create a torque difference in a tilting hinge, the tilting hinge includes a fixture consisting of a fixing plate portion to be fixed to the body of a portable computer and a bearing plate portion bent perpendicularly to the fixing plate portion; a rotating shaft consisting of a fixing portion to be fixed to a display screen of the portable computer, a large-diameter portion and a small-diameter portion, and born relatively rotatably in a bearing hole formed in the bearing plate portion of the fixture; a first friction washer having a through-hole formed in the center thereof and disposed between the large-diameter portion of the rotating shaft and one side of the bearing plate portion rotatably with the rotating shaft being inserted in the central through-hole or disposed in engagement with the bearing plate portion; a second friction washer having a through-hole formed in the center thereof and disposed fixed to the bearing plate portion with the rotating shaft being inserted at the small-diameter portion thereof in the central through-hole or rotatably with the rotating shaft; an elastic assembly of a spring washer or spring washers, a belleville spring or belleville springs, a wave washer or wave washers, etc. each having a through-hole formed in the center thereof, the assembly being disposed to abut on the second friction washer with the rotating shaft being inserted at the small-diameter portion thereon in the central through-hole; a set washer having a through-hole formed in the center thereof and disposed to abut on the elastic assembly rotatably with the rotating shaft being inserted at the small-diameter portion thereof in the central through-hole; the rotating shaft having a to-be-calked projection, from the set washer, of the small-diameter portion thereof; and a torque controlling means for generating, axially of the rotating shaft at either of the sides of the bearing plate portion, a torque varying depending upon the angle of rotation of the rotating shaft.
