HINGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/009808
Kind Code:
A1
Abstract:
Provided is a hinge device that is capable of avoiding shock when a lid is closed. This hinge device 5 comprises a first hinge body 6 that is secured to a casing 2 (first object), a second hinge body 7 that is secured to a lid 3 (second object), and a shaft member 8 that links the two hinge bodies 6, 7. The hinge device 5 furthermore comprises a a one-way clutch 30, a frictional-resistance-generating mechanism 40, and a damper mechanism 50. The one-way clutch 30 does not generate frictional resistance when the lid 3 is opened, and generates frictional resistance only when the lid 3 is closed. The lid 3 is anchored at a discretionary position from an upright position to a prescribed angle by the frictional resistance. Torque produced by the weight of the lid 3 overcomes the frictional resistance within an angular range near a closed position, and the lid 3 rotates in a closing direction. When this occurs, a damper effect of the damper mechanism operates in addition to the frictional resistance, therefore making it possible to avoid shock when the lid 3 is suppressed from rotating and is closed.
