DEFINITION

Classification: 16/337

By friction:

(under subclass 319) Hinge including two opposing surfaces, each of which is formed on or connected to a respective hinged member* and wherein movement of the hinged members is prevented or retarded due to the frictional resistance to movement of one surface over the other.

SEE OR SEARCH THIS CLASS, SUBCLASS:

321+, for a resiliently biased catch which fixes the hinged members in a specific relative position by engaging cooperating structure at a specific point during the swinging movement of the hinged members.
