Friction hinge
First Claim
Patent Images
1. A device comprising:
- a support component movably attached to a rear portion of the device; and
at least one hinge that moveably attaches a portion of the support component to the device, the hinge including;
a hinge frame;
a pivot member pivotably engaged with the hinge frame, the pivot member attached to the support component;
a friction pin attached to the pivot member; and
a hinge band with a guide pin slidably engaged with a guide slot within the hinge frame, the friction pin rotatably engaged with the hinge band such that during pivoting of the pivot member relative to the hinge frame, the friction pin rotates relative to the hinge band and frictional resistance to rotation of the friction pin relative to the hinge band contributes to a torque profile of the hinge, the guide slot having variable slot angles relative to a longitudinal axis of the hinge frame.

9. A hinge comprising:
-
a hinge frame; a pivot member pivotably engaged with the hinge frame; a friction pin attached to the pivot member; and a hinge band with a guide pin slidably engaged with a guide slot within the hinge frame, the friction pin rotatably engaged with the hinge band such that during pivoting of the pivot member relative to the hinge frame, the friction pin rotates relative to the hinge band and frictional resistance to rotation of the friction pin relative to the hinge band contributes to a torque profile of the hinge, the guide slot having different action zones that have different respective slot angles relative to a longitudinal axis of the hinge frame. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus comprising:
-
a chassis; a moveable component moveably attached to the chassis; and a hinge that moveably attaches the moveable component to the chassis, the hinge including; a hinge frame; a pivot member pivotably engaged with the hinge frame, the pivot member attached to the moveable component; a friction pin attached to the pivot member; and a hinge band with a guide pin slidably engaged with a guide slot within the hinge frame, the friction pin rotatably engaged with the hinge band such that during pivoting of the pivot member relative to the hinge frame, the friction pin rotates relative to the hinge band and frictional resistance to rotation of the friction pin relative to the hinge band contributes to a torque profile of the hinge, the guide slot having different action zones that have different respective slot angles relative to the hinge frame. - View Dependent Claims (16, 17, 18, 19, 20)
