Document Type and Number:
WIPO Patent Application WO/2020/208796
Kind Code:
A1
Abstract:
Provided is a hinge structure that can easily and safely open and close a lid (9) of a type with a low center of gravity (9c) using a spring force. The hinge structure is provided with a first member (1); a second member (2); a rotation shaft (3); and a link mechanism (4). The first member (1) is attached to a container (8) having an opening (81). The second member (2) is attached to the lid (9). The rotation shaft (3) rotatably connects the first member (1) and the second member (2) to each other. The link mechanism (4) connects the first member (1) and the second member (2) to each other at a spot different from the rotation shaft (3). A spring mechanism (7) included in the link mechanism (4) applies a torque to the second member (2) in a direction in which the lid (9) is opened. In a state in which the lid (9) closes the opening (81), a shaft center (3a) of the rotation shaft (3) is positioned above the center of gravity (9c) of the lid (9). The link mechanism (4) applies a torque to the second member (2) so as to cause the lid (9) to stand still in any posture thereof including a posture in which the opening (81) is closed.
