DEFINITION

Classification: 16/319

Including means to hold or retard hinged members against pivotal movement(e.g., catch):

(under subclass 221) Hinge including either means to secure the hinged members* to prevent any swinging or means for producing a drag and thereby preventing the members from swinging freely about the hinge axis*.

(1) Note. The members must be secured against swinging movement in both directions, i.e., an abutment stop, per se, is excluded.

SEE OR SEARCH THIS CLASS, SUBCLASS:

292, for a hinge biased by a transverse helical spring and having a catch.

297, for a spring hinge having a catch.

317, for a gravitating hinge having a catch.

374+, for a hinge having a stop or abutment.

84, for articulated members which are lockable at selected angles.
