Abstract
The present invention relates to a hinge device comprising: a casing having a projection hole; a cam provided in the casing, the cam being rotatable with respect to a rotational axis, movable in the direction of the rotational axis, and undetachable from the casing, the cam having a projection projecting through the projection hole and a cam face surrounding the rotational axis; a flat spring for holding the cam face; a base movable in the direction of the rotational axis, the cam being rotatably attached to the base; and a pressing spring for urging the cam and the base toward the direction of the projection.
Claims19
A hinge device comprising:
- a casing having a projection hole;
- a cam provided in said casing, said cam being rotatable with respect to a rotational axis, moveable with respect to said casing in the direction of the rotational axis, and undetachable from said casing, said cam having a projection retractable projecting through said projection hole and a cam face surrounding the rotational axis;
- a flat spring for holding said cam face;
- a base moveable with respect to said casing in the direction of the rotational axis, said cam being rotatably attached to said base;
- and
- a compression spring for urging said cam and said base toward the direction of said projection.
A flip member, which is pivotally connected to a main body by means of a hinge device, said hinge device comprising:
- a casing having a projection hole;
- a cam provided in said casing, said cam being rotatable with respect to a rotational axis, movable with respect to said casing in the direction of the rotational axis, and undetachable from said casing, said cam having a projection retractable projecting through said projection hole and a cam face surrounding the rotational axis;
- a flat spring for holding said cam face;
- a base movable with respect to said casing in the direction of the rotational axis, said cam being rotatably attached to said base;
- and
- a compression spring for urging said cam and said base toward the direction of said projection.
An electronic device having two members, which are pivotally interconnected by means of a hinge device, said hinge device comprising:
- a casing having a projection hole;
- a cam provided in said casing, said cam being rotatable with respect to a rotational axis, movable with respect to said casing in the direction of the rotational axis, and undetachable from said casing, said cam having a projection retractably projecting through said projection hole and a cam face surrounding the rotational axis;
- a flat spring for holding said cam face;
- a base movable with respect to said casing in the direction of the rotational axis, said cam being rotatably attached to said base;
- and
- a compression spring for pressing said cam and said base toward the direction of said projection.
