Description

  The present invention connects an opening / closing member such as a lid or a display to an apparatus main body such as a notebook personal computer so as to be freely opened and closed, and holds the opening / closing member in an arbitrary opened / closed state. The present invention relates to a hinge having a click stop means for stably maintaining the position.

  As a conventional hinge of this type, for example, the click stopping means rotates with a rotating shaft provided between the device main body and the opening / closing member, a ball engaged with the cam plate, and the ball Some of them are composed of elastic means for pressing the cam plate against the cam plate. (See Patent Document 1) Further, it is composed of a hinge shaft positioned on one of the fixed side and the movable side, and a U-shaped leaf spring positioned on the other side and rotatably attached to the hinge shaft. In addition, there is a hinge device configured such that a cam protrusion is formed on the leaf spring and a click feeling is obtained by relative rotation of the hinge shaft and the leaf spring. (For example, see Patent Document 2)

  However, since the conventional technique of Patent Document 1 is configured such that the ball is pressed against the cam plate by elastic means, if the elastic force is weak, the click stop (opening / closing member closed) state becomes unstable and elastic When the force is increased to increase the friction torque, not only the ball and the cam plate are easily worn, but also the opening / closing member has to be rotated with a strong force.

Further, the prior art disclosed in Patent Document 2 has a limit in stably maintaining the closed state of the opening / closing member by the leaf spring.
