摘要:
A hinge assembly includes a first and a second set of friction elements engaged each other by an applied force perpendicular to the friction elements. The first and the second set of friction elements are capable of rotational movement about a cylindrical element that passes through each of the friction elements. Also, the first set of friction elements is capable of movement relative to the second set of friction elements. However, the first set friction elements can remain in a fixed position based upon the applied force, until an external force overcomes the applied. During rotation of the first set of friction elements about the cylindrical element, the frictional engagement that controls the position of the first set of friction elements is based primarily on engagement between the friction elements, as opposed to engagement, if any, between the friction elements and the cylindrical element.
