Abstract
To provide a hinge assembly with a good operability for a portable equipment composed of a first case body and a second case body, such as a portable telephone and a portable video game machine, etc., the above-indicated first case body and second case body are structured, allowing a relative rotation from a closing condition, i.e. a superposition of the above-indicated case bodies in two directions, i.e. a longitudinal and right and left direction. Further a locking mechanism is used to prevent the above-described bodies from opening in either one direction, when they are opened in either other one of two of the above-indicated directions.
Claims12
A hinge device of a portable equipment for relatively opening and closing a first case body and a second case body of said portable equipment in either one of two directions, a longitudinal direction and a right and left direction, from a closing condition, where a first case body and a second case body are superimposed on each other, said hinge device comprising:
- a first shaft attached to either one of said first case body and said second case body;
- a second shaft attached to either other one of said first case body and said second case body;
- a base portion for supporting said first shaft and said second shaft so as to be each rotatable around a respective axis;
- a first cam mechanism for restricting the rotation of said first shaft with regard to the base portion;
- a second cam mechanism for restricting the rotation of said second shaft with regard to the base portion;
- a locking mechanism for allowing said first case body and said second case body, when said first case body and said second case body are in a closing condition, to be opened and closed in said two directions, and for locking said first case body and said second case body against closing/opening in either other direction when said first case body and said second case body are opened in either one direction of said two directions.
