20090126156 | Pivot Pin with Gripper Feature - A swinging door hinge has a panel and a frame. The frame includes a horizontal portion, and the horizontal portion has an aperture therethrough. An elongated pivot pin is vertically disposed through the aperture. The pivot pin is coupled to the panel such that the pivot pin and the panel rotate about a longitudinal axis of the pivot pin relative to the horizontal portion of the frame. A gripper feature is located on a surface of the pivot pin. The gripper feature engages a corresponding surface on the panel such that when the panel is rotated, a resulting torsional force transferred to the pivot pin is spread over a contact area between the gripper feature and the surface of the panel. Because the torque is transferred over a greater area, stress concentrations in the panel are reduced and the panel is not deformed. | 05-21-2009 |
20090205168 | HINGE ASSEMBLY AND PORTABLE ELECTRONIC DEVICE USING THE SAME - A hinge assembly and a portable electronic device are provided. The portable electronic device includes a lid, a main body, and a hinge assembly. The hinge assembly pivotly connects the lid to the main body. The hinge assembly includes a pivot element, a torsion spring, and a hinge brace. The pivot element is formed on the lid and partially and rotatably received in the main body. The torsion spring is assembled between the lid and the main body. When the lid is in a closed position with respect to the main body, the torsion spring becomes constricted and accumulates potential energy. When the lid is opened from the main body, the potential energy of the torsion spring is released to drive the lid to rotate to an open position with respect to the main body. The hinge brace is attached to the main body for blocking an excessive rotation of the lid with respect to the main body. | 08-20-2009 |
