    Abstract: Self-closing pivot hinges and devices such as doors for closing off an opening between two rooms or in a building façade using such hinges include a spring that extends into a hinge housing along the longitudinal direction of the hinge housing, which lends a self-closing function, and a cam element and a ball that is pressed against the cam element by the spring. The cam element is shaped so that it creates support positions in which the ball rests.

    Abstract: A vehicle door opening and closing operation device includes a cover swing mechanism and a door opening and closing operation portion to be operated by a user. The cover swing mechanism has a cover member that moves between a closed position where an operation opening portion is closed and an open position where the operation opening portion is opened. The cover swing mechanism includes a swing link unit and a swing unit. The swing link unit is swingable and movably supports the cover member between the closed position and the opening position. The swing unit includes a cam member. The swing unit presses an engagement portion of the link unit by a protruding portion provided on the cam member and swings the link unit to move the cover member. At least a part of the engagement portion overlaps the cam member in a front view.

    Abstract: A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.
