First Claim
Patent Images
1. A hinge comprising:
- a first friction assembly configured to provide resistance to movement of the hinge across a first angle range; and
a second friction assembly configured to provide resistance to movement of the hinge across a second angle range;
a hinge frame including at least one ring guide;
an upper hinge ring slidably engaged with the at least one ring guide;
a lower hinge ring interlocked with the upper hinge ring and including a lower ring spring disposed on an inner surface of the lower hinge ring; and
a cam positioned at least in part between the upper hinge ring and the lower hinge ring such that when the hinge is positioned within the first angle range, the cam engages with the lower ring spring to form at least a part of the first friction assembly.

Abstract
A multistage friction hinge is described. In at least some embodiments, the described hinge enables a support component to be adjustably attached to an apparatus. According to various embodiments, a hinge includes different activity stages where movement of the hinge is based on different activity mechanisms. For instance, the hinge includes different sets of components that form different friction engines that provide resistance to rotational and/or pivoting movement of the hinge.

11. A hinge comprising:
-
a hinge frame; an upper hinge ring slidably engaged with the hinge frame; a lower hinge ring interlocked with the upper hinge ring; and a cam positioned at least in part between the upper hinge ring and the lower hinge ring, the cam including a spring biased locking tab such that when the cam transitions from a first angle range of the hinge to a second angle range of the hinge, the locking tab engages with the upper hinge ring and movement of the cam within the second angle range causes corresponding movement of the upper hinge ring and the lower hinge ring from the first angle range to the second angle range. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
