DEFINITION

Classification: 280/124.126

Steering pivot confined within boundary of wheel:

(under subclass 124.125) Subject matter wherein the suspension interconnects a steerable wheel to the vehicle body, chassis, or frame such that the connection points defining a turning axis of the wheel lie within the area defined by the perimeter and treadwidth of the wheel.

(1) Note. Excluded from this subclass is a telescopically mounted steerable or steered swivel truck wherein the pivot axis is vertically aligned with the wheel center plane but actually displaced above the rotational axis of the wheel.

SEE OR SEARCH THIS CLASS, SUBCLASS:

47.11, for an attendant steered vehicle having steering control means for other than a mere swinging axle.

47.34+, for a stable, handle-propelled vehicle which may or may not include a steerable wheel.

86+, for a nonsteerable swivel truck (i.e., caster wheel).

87.01+, for a coaster vehicle which may or may not include a steerable wheel.

124.117+, for a telescopically mounted steerable or steered swivel truck wherein the pivot axis is vertically aligned with the wheel center plane but actually displaced above the rotational axis of the wheel. 200+, appropriate subclasses for an occupant-propelled-type wheeled land vehicle including a steerable wheel. Additionally, in accordance with the (2) Note of subclass 200, motorcycle frames and running gear without features causing classification in Class 180, Motor Vehicles, are included in these subclasses.
