Hinge device with a returning member for automatically closing an open door |
摘要 |
A hinge member includes a rotatable cam element with a first cam face and a slidable cam element with a second cam face associated with the first cam face in such a manner that the second cam face moves away from the first cam face when the slidable cam element is cammed by the rotatable cam element due to an applied external force. A biasing member is connected to the slidable cam element so as to accumulate a returning force when the second cam face moves away from the first cam face and so as to urge the second cam face to move toward the first cam face when the external force ceases to be applied on the rotatable cam element. |
