Patent ID: 8196261

Claim:
A movable range switching tilt hinge comprising: a movable range fixed tilt hinge comprising a spindle extending in an axial direction, a movable bracket rotatably arranged around said spindle and having a projecting piece, a fixed bracket fixed to said spindle, a stopper fixed to said spindle and having first and second cam portions, said stopper restricting a moving range of said movable bracket within a first movable range by engaging the projecting piece with the first and the second cam portions, and a friction imparting arrangement having a friction built between said movable bracket and said fixed bracket; and a movable range switching member mounted on said movable bracket, said movable range switching member being able to switch the moving range of said movable bracket between the first movable range and a second movable range smaller than the first movable range, wherein said movable bracket comprises a movable plate extending in a direction orthogonal to the axial direction of said spindle, wherein said movable range switching member comprises: a shaft extending in parallel with the axial direction of said spindle, said shaft being movably mounted in the axial direction against said movable plate; and a movable metal sheet mounted to said shaft and having a protrusion piece, said movable metal sheet moving the protrusion piece, by moving in the axial direction, between a first position at which the protrusion piece is able to be engaged with said first cam portion and a second position at which the protrusion piece is unable to be engaged with said first cam portion, whereby said movable range switching tilt hinge switches the moving range of said movable bracket to the second movable range when the protrusion piece is moved to the first position.
