.~.~ Circumferentially divided engaging element type
DEFINITION
Classification: 157/1.42
(under subclass 1.35) Devices in which at least one of the rim-engaging elements consists of two or more circumferentially spaced rim contacting portions which are by appearance distinct, but which are in fact the terminal portions of integrally connected arms, thereby forming a single engaging element as defined for subclass 1.36 in (1) Note thereunder.
(1) Note. The integral connection between the arms is sufficient for this subclass if the arms are so mounted that relative movement circumferentially of the rim in either direction is precluded when the device is in extended condition ready for use.
SEE OR SEARCH THIS CLASS, SUBCLASS:
1.36, for devices having similar structure, but in which relative movement between the arms is permitted.
