Abstract

The description relates to hinged devices. One example can include a spine defining inner and outer arced surfaces and a hinge arm positioned between the inner and outer arced surfaces and configured to arcuately move from a retracted position to a fully extended position. The example includes an anti-lock link captured between the spine and the hinge arm to move along an arc. Rotation of the hinge arm to the fully extended position is configured to rotate the anti-lock link along the arc and partially out of the spine until the anti-lock link contacts the spine and blocks further extension of the hinge arm. Reverse rotation of the hinge arm from the fully extended position toward the retracted position is configured to initially cause the hinge arm to contact the anti-lock link and not the outer arced surface.
