Abstract
A hinge device for a foldable apparatus includes first and second hinge sleeves () connected respectively to two parts of the foldable apparatus, a spring member () received in the first hinge sleeve, a first disk () fitted untreatably into the first sleeve, a second disk () fitted unrotatably into the second sleeve and abutting the first disk, a pin () sandwiched between the first and second disk, and a shaft () combining the first and second hinge sleeves together. The first disk defines a receiving recess () to receive the pin. The second disk defines two engaging recesses (). By opening and closing motions of the foldable apparatus, the second disk rotates relative to the first disk so that the pin received in the receiving recess switchably moves with rotation from one engaging recess to the other engaging recess.
