Multistage friction hinge
First Claim
Patent Images
1. A device comprising:
- a support movably attached to a rear portion of the device; and
at least one multistage friction hinge that moveably attaches a portion of the support to the device, the hinge including;
a first angle range in which resistance to movement of the hinge is determined based on engagement of a first friction engine of the hinge; and
a second angle range in which resistance to movement of the hinge is determined based on engagement of a second friction engine of the hinge, the hinge further including;
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 attached to the support and 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 the first angle range to the second angle range, 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 to form at least a part of the second friction engine.

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.
