Sticking the open time moving the destal

摘要

PROBLEM TO BE SOLVED: To provide a hinge device automatically rotated by quick operation and rotated at low speed to a maximum open position and locked to rotate at the maximum open position.;SOLUTION: In this hinge device, when a first member 1 is rotated so as to be openable relative to a second member 2 by a rotatingly energizing mechanism 4 by releasing a closing holding mechanism 3 from the overlappingly closed state of the first member 1 and the second member 2, the hinge device is rotated at low speed by the damping of the energizing force of the rotating energizing mechanism 4 by an increase in opening angle, rotating resistance by a friction surface 12, or a change in gravity applied to the first member 1 until at least the first member 1 or the second member 2 are brought into the maximum open state from the raised state from the second member 2 or the first member 1. A friction resistance force by the friction surface 12 is set so that the first member 1 and the second member 2 can be rotated so as to be openable to the maximum open state that an engagement recessed part 7A and an engagement recessed part 8A are brought into an engaged state by the energizing force of the rotatingly energizing mechanism 4 or the gravity applied to the first member 1 while the hinge device is in a stat of being rotated at low speed.;COPYRIGHT: (C)2006,JPO&NCIPI
