Abstract
A hinge mechanism 1 includes a rotation shaft 3 connected to a monitor and serving as rotating central axis X; a base 2 pivotally supporting the shaft 3 rotatably, and having click recesses 2b1, 2b2 and a housing position determining recess 2c on a circumference centering the axis X; a plate 5 attached at the end of the shaft 3; and a leaf spring 4 located between the base 2 and plate 5, fit-in by the rotation shaft 3, and having a click projection 4b that fits in the click recesses 2b1, 2b2 and recess 2c to hold the monitor in a predetermined rotation angle position. A sliding friction projection 4c sliding with pressed into contact with the base 2 is formed on the side opposite from the click projection 4b across the axis X, while a cutaway 2e entered by the projection 4c is formed in the base 2.
Claims10
A hinge mechanism including:
- a shaft that is connected with a rotating body and serves as an axis of rotation;
- a base that pivotally supports the shaft to be rotatable, and also has a click recess on a circumference centering the axis of rotation;
- a plate that is attached at an end portion of the shaft in such manner that the plate and the shaft are rotated integrally with each other;
- and
- a leaf spring that is located between the base and the plate, and into which is fitted the shaft in such manner that the leaf spring and the shaft are rotated integrally with each other,
- wherein the leaf spring has a click projection that engages with the click recess that is provided in the base to thus hold the rotating body in a predetermined rotation angle position,
- wherein the leaf spring has a sliding friction projection that slides when pressed into contact with the base, the sliding friction projection being on an opposite side of the axis of rotation with respect to the click projection, and
- wherein the plate includes a drawn recess that receives the sliding friction projection as the sliding friction projection is pressed into contact with a surface of the base.
