DEFINITION

Classification: 157/1.36

(under subclass 1.35) Devices having three or more rim-engaging elements.

(1) Note. In determining the number of elements, those which are rigidly connected together and those which engage on opposite edges or faces of the rim in substantially the same radial plane, as well as those combinations of members which constitute a unitary rim clamping structure are regarded as single elements.
