DEFINITION

Classification: 280/1.184

(under subclass 1.182) Vehicles in which there is present some means, in addition to the two relatively approaching and separating supports to engage the ground or surface over which the vehicle moves, either to stabilize the figure, assist in propelling it, or impart a different type of motion.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1.175, for progressing rocker type simulations having a similar ground engaging means.

1.188, for other velocipede type simulations convertible to have more than one kind of motion.

219, for nonsimulation vehicles propelled by means intermittently engaging the ground or floor.
