    • A ring mechanism includes a chassis and a hinge blade coupled to the chassis. An actuator coupled to the chassis moves the hinge blade between a first position and a second position. A ring half coupled to the hinge blade is positioned in a closed position when the hinge blade is in the first position, and an open position when the hinge blade is in the second position. A dampening member is positioned at least partially between the inner surface of the chassis and the actuator to prevent at least a portion of the actuator from directly engaging the inner surface of the chassis during movement of the actuator between the first and second positions. A locked state indicator indicates to the user whether the ring mechanism is in a locked position or an unlocked position. The dampening member can function as the lock state indicator and vice versa.
    • 环形机构包括底盘和联接到底盘的铰链叶片。 联接到底盘的致动器使铰链叶片在第一位置和第二位置之间移动。 当铰链叶片处于第一位置时,耦合到铰链叶片的环形半部被定位在关闭位置,并且当铰链叶片处于第二位置时,环形部分处于打开位置。 阻尼构件至少部分地定位在底盘的内表面和致动器之间,以防止致动器的至少一部分在致动器在第一和第二位置之间移动期间直接接合底盘的内表面。 锁定状态指示器向用户指示环机构是处于锁定位置还是解锁位置。 阻尼构件可用作锁定状态指示器,反之亦然。
