DEFINITION

Classification: 16/321

Resiliently biased catch:

(under subclass 319) Hinge having means to secure the hinged

members* in a specific relative position about the hinge axis*, the means including two cooperating elements or portions, and elastically deformable means which acts to move or force one of the elements or portions relative to the other to hold the hinged members in the specific position.

(1) Note. A portion of the elastically deformable means (spring) may serve as a cooperating portion.

(2) Note. A resiliently biased friction pad by which the hinged members may be fixed at any position during their swing about the hinge axis is excluded.

SEE OR SEARCH THIS CLASS, SUBCLASS:

337+, for a hinge having a friction drag or a resiliently biased friction pad as specified in (2) Note above.
