DEFINITION

Classification: 16/278

Including means to render spring ineffective through all or a portion of swing:

(under subclass 277) Hinge wherein either (a) selectively actuated means are provided to release the hinged member* to swing without bias from the elastically deformable element, or (b) the hinge member swings under bias from the elastically deformable element through a first arc about the hinge axis*, and then swings without bias from the elastically deformable element through a second adjacent arc, or vice versa.

(1) Note. The elastically deformable element must provide bias through a substantial arc during swinging movement of the hinged member* about the hinge axis*.

SEE OR SEARCH THIS CLASS, SUBCLASS:

255+, for a hinge having a resiliently biased catch by which a hinged member* "snaps" into open or closed position, but is not biased during the remainder of the swing.
